That's because Chrome added support for source maps.

Go to the developer tools (F12 in the browser), then select the three dots in the upper right corner, and go to Settings.

Then, look for Sources, and disable the options: "Enable javascript source maps" "Enable CSS source maps"

If you do that, that would get rid of the warnings. It has nothing to do with your code. Check the developer tools in other pages and you will see the same warning.

What fixed it for me was plugging my iPhone and allowing it as a simulator destination. Doing so required my to register my iPhone in Apple Dev account and once that was done and I ran my project from Xcode on my iPhone everything fixed itself.

1. Connect your iPhone to your Mac
2. Xcode>Window>Devices & Simulators
3. Add new under Devices and make sure "show are run destination" is ticked
4. Build project and run it on your iPhone

this worked for me

// using Microsoft.AspNetCore.Authentication.Cookies;
// using Microsoft.AspNetCore.Http;

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
        options =>
        {
            options.LoginPath = new PathString("/auth/login");
            options.AccessDeniedPath = new PathString("/auth/denied");
        });

you can try to this , then you get a bitmap of selected image and then you can easily find it's native path from Device Default Gallery.

Bitmap roughBitmap= null;
    try {
    // Works with content://, file://, or android.resource:// URIs
    InputStream inputStream =
    getContentResolver().openInputStream(uri);
    roughBitmap= BitmapFactory.decodeStream(inputStream);

    // calc exact destination size
    Matrix m = new Matrix();
    RectF inRect = new RectF(0, 0, roughBitmap.Width, roughBitmap.Height);
    RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
    m.SetRectToRect(inRect, outRect, Matrix.ScaleToFit.Center);
    float[] values = new float[9];
    m.GetValues(values);


    // resize bitmap if needed
    Bitmap resizedBitmap = Bitmap.CreateScaledBitmap(roughBitmap, (int) (roughBitmap.Width * values[0]), (int) (roughBitmap.Height * values[4]), true);

    string name = "IMG_" + new Java.Text.SimpleDateFormat("yyyyMMdd_HHmmss").Format(new Java.Util.Date()) + ".png";
    var sdCardPath= Environment.GetExternalStoragePublicDirectory("DCIM").AbsolutePath;
    Java.IO.File file = new Java.IO.File(sdCardPath);
    if (!file.Exists())
    {
        file.Mkdir();
    }
    var filePath = System.IO.Path.Combine(sdCardPath, name);
    } catch (FileNotFoundException e) {
    // Inform the user that things have gone horribly wrong
    }

The path to the nginx.conf file which is the primary Configuration file for Nginx - which is also the file which shall INCLUDE the Path for other Nginx Config files as and when required is /etc/nginx/nginx.conf.

You may access and edit this file by typing this at the terminal

cd /etc/nginx

/etc/nginx$ sudo nano nginx.conf

Further in this file you may Include other files - which can have a SERVER directive as an independent SERVER BLOCK - which need not be within the HTTP or HTTPS blocks, as is clarified in the accepted answer above.

I repeat - if you need a SERVER BLOCK to be defined within the PRIMARY Config file itself than that SERVER BLOCK will have to be defined within an enclosing HTTP or HTTPS block in the /etc/nginx/nginx.conf file which is the primary Configuration file for Nginx.

Also note -its OK if you define , a SERVER BLOCK directly not enclosing it within a HTTP or HTTPS block , in a file located at path /etc/nginx/conf.d . Also to make this work you will need to include the path of this file in the PRIMARY Config file as seen below :-

http{
    include /etc/nginx/conf.d/*.conf; #includes all files of file type.conf
}

Further to this you may comment out from the PRIMARY Config file , the line

http{
    #include /etc/nginx/sites-available/some_file.conf; # Comment Out 
    include /etc/nginx/conf.d/*.conf; #includes all files of file type.conf
}

and need not keep any Config Files in /etc/nginx/sites-available/ and also no need to SYMBOLIC Link them to /etc/nginx/sites-enabled/ , kindly note this works for me - in case anyone think it doesnt for them or this kind of config is illegal etc etc , pls do leave a comment so that i may correct myself - thanks .

EDIT :- According to the latest version of the Official Nginx CookBook , we need not create any Configs within - /etc/nginx/sites-enabled/ , this was the older practice and is DEPRECIATED now .

Thus No need for the INCLUDE DIRECTIVE include /etc/nginx/sites-available/some_file.conf; .

Quote from Nginx CookBook page - 5 .

"In some package repositories, this folder is named sites-enabled, and configuration files are linked from a folder named site-available; this convention is depre- cated."

I tried the option: Tools > Preferences > Syntax coloring > dark spyder is not working.

You should rather use the path: Tools > Preferences > Syntax coloring > spyder then begin modifications as you want your editor to appear

See,

There are two ways to convert an RDD to DF in Spark.

toDF() and createDataFrame(rdd, schema)

I will show you how you can do that dynamically.

toDF()

The toDF() command gives you the way to convert an RDD[Row] to a Dataframe. The point is, the object Row() can receive a **kwargs argument. So, there is an easy way to do that.

from pyspark.sql.types import Row

#here you are going to create a function
def f(x):
    d = {}
    for i in range(len(x)):
        d[str(i)] = x[i]
    return d

#Now populate that
df = rdd.map(lambda x: Row(**f(x))).toDF()

This way you are going to be able to create a dataframe dynamically.

createDataFrame(rdd, schema)

Other way to do that is creating a dynamic schema. How?

This way:

from pyspark.sql.types import StructType
from pyspark.sql.types import StructField
from pyspark.sql.types import StringType

schema = StructType([StructField(str(i), StringType(), True) for i in range(32)])

df = sqlContext.createDataFrame(rdd, schema)

This second way is cleaner to do that...

So this is how you can create dataframes dynamically.

There is a solution to this if you really need a static access to the current context. In Startup.Configure(….)

app.Use(async (httpContext, next) =>
{
    CallContext.LogicalSetData("CurrentContextKey", httpContext);
    try
    {
        await next();
    }
    finally
    {
        CallContext.FreeNamedDataSlot("CurrentContextKey");
    }
});

And when you need it you can get it with :

HttpContext context = CallContext.LogicalGetData("CurrentContextKey") as HttpContext;

I hope that helps. Keep in mind this workaround is when you don’t have a choice. The best practice is to use de dependency injection.

In your particular example you'd do the following routerLink:

[routerLink]="['user', user.id, 'details']"

To do so in a controller, you can inject Router and use:

router.navigate(['user', user.id, 'details']);

More info in the Angular docs Link Parameters Array section of Routing & Navigation

OK, but you don`t want to open the whole realtime database! You need something like this.

{
  /* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */
  "rules": {
    ".read": "auth.uid !=null",
    ".write": "auth.uid !=null"
  }
}

or

{
  "rules": {
    "users": {
      "$uid": {
        ".write": "$uid === auth.uid"
      }
    }
  }
}

Original

This is how I got client certification working and checking that a specific Root CA had issued it as well as it being a specific certificate.

First I edited <src>\.vs\config\applicationhost.config and made this change: <section name="access" overrideModeDefault="Allow" />

This allows me to edit <system.webServer> in web.config and add the following lines which will require a client certification in IIS Express. Note: I edited this for development purposes, do not allow overrides in production.

For production follow a guide like this to set up the IIS:

https://medium.com/@hafizmohammedg/configuring-client-certificates-on-iis-95aef4174ddb

web.config:

<security>
  <access sslFlags="Ssl,SslNegotiateCert,SslRequireCert" />
</security>

API Controller:

[RequireSpecificCert]
public class ValuesController : ApiController
{
    // GET api/values
    public IHttpActionResult Get()
    {
        return Ok("It works!");
    }
}

Attribute:

public class RequireSpecificCertAttribute : AuthorizationFilterAttribute
{
    public override void OnAuthorization(HttpActionContext actionContext)
    {
        if (actionContext.Request.RequestUri.Scheme != Uri.UriSchemeHttps)
        {
            actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
            {
                ReasonPhrase = "HTTPS Required"
            };
        }
        else
        {
            X509Certificate2 cert = actionContext.Request.GetClientCertificate();
            if (cert == null)
            {
                actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
                {
                    ReasonPhrase = "Client Certificate Required"
                };

            }
            else
            {
                X509Chain chain = new X509Chain();

                //Needed because the error "The revocation function was unable to check revocation for the certificate" happened to me otherwise
                chain.ChainPolicy = new X509ChainPolicy()
                {
                    RevocationMode = X509RevocationMode.NoCheck,
                };
                try
                {
                    var chainBuilt = chain.Build(cert);
                    Debug.WriteLine(string.Format("Chain building status: {0}", chainBuilt));

                    var validCert = CheckCertificate(chain, cert);

                    if (chainBuilt == false || validCert == false)
                    {
                        actionContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.Forbidden)
                        {
                            ReasonPhrase = "Client Certificate not valid"
                        };
                        foreach (X509ChainStatus chainStatus in chain.ChainStatus)
                        {
                            Debug.WriteLine(string.Format("Chain error: {0} {1}", chainStatus.Status, chainStatus.StatusInformation));
                        }
                    }
                }
                catch (Exception ex)
                {
                    Debug.WriteLine(ex.ToString());
                }
            }

            base.OnAuthorization(actionContext);
        }
    }

    private bool CheckCertificate(X509Chain chain, X509Certificate2 cert)
    {
        var rootThumbprint = WebConfigurationManager.AppSettings["rootThumbprint"].ToUpper().Replace(" ", string.Empty);

        var clientThumbprint = WebConfigurationManager.AppSettings["clientThumbprint"].ToUpper().Replace(" ", string.Empty);

        //Check that the certificate have been issued by a specific Root Certificate
        var validRoot = chain.ChainElements.Cast<X509ChainElement>().Any(x => x.Certificate.Thumbprint.Equals(rootThumbprint, StringComparison.InvariantCultureIgnoreCase));

        //Check that the certificate thumbprint matches our expected thumbprint
        var validCert = cert.Thumbprint.Equals(clientThumbprint, StringComparison.InvariantCultureIgnoreCase);

        return validRoot && validCert;
    }
}

Can then call the API with client certification like this, tested from another web project.

[RoutePrefix("api/certificatetest")]
public class CertificateTestController : ApiController
{

    public IHttpActionResult Get()
    {
        var handler = new WebRequestHandler();
        handler.ClientCertificateOptions = ClientCertificateOption.Manual;
        handler.ClientCertificates.Add(GetClientCert());
        handler.UseProxy = false;
        var client = new HttpClient(handler);
        var result = client.GetAsync("https://localhost:44331/api/values").GetAwaiter().GetResult();
        var resultString = result.Content.ReadAsStringAsync().GetAwaiter().GetResult();
        return Ok(resultString);
    }

    private static X509Certificate GetClientCert()
    {
        X509Store store = null;
        try
        {
            store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
            store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadOnly);

            var certificateSerialNumber= "?81 c6 62 0a 73 c7 b1 aa 41 06 a3 ce 62 83 ae 25".ToUpper().Replace(" ", string.Empty);

            //Does not work for some reason, could be culture related
            //var certs = store.Certificates.Find(X509FindType.FindBySerialNumber, certificateSerialNumber, true);

            //if (certs.Count == 1)
            //{
            //    var cert = certs[0];
            //    return cert;
            //}

            var cert = store.Certificates.Cast<X509Certificate>().FirstOrDefault(x => x.GetSerialNumberString().Equals(certificateSerialNumber, StringComparison.InvariantCultureIgnoreCase));

            return cert;
        }
        finally
        {
            store?.Close();
        }
    }
}

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

Why "Accepted Answer" works... but it wasn't enough for me

This works in the specification. At least swagger-tools (version 0.10.1) validates it as a valid.

But if you are using other tools like swagger-codegen (version 2.1.6) you will find some difficulties, even if the client generated contains the Authentication definition, like this:

this.authentications = {
  'Bearer': {type: 'apiKey', 'in': 'header', name: 'Authorization'}
};

There is no way to pass the token into the header before method(endpoint) is called. Look into this function signature:

this.rootGet = function(callback) { ... }

This means that, I only pass the callback (in other cases query parameters, etc) without a token, which leads to a incorrect build of the request to server.

My alternative

Unfortunately, it's not "pretty" but it works until I get JWT Tokens support on Swagger.

Note: which is being discussed in

• security: add support for Authorization header with Bearer authentication scheme #583
• Extensibility of security definitions? #460

So, it's handle authentication like a standard header. On path object append an header paremeter:

swagger: '2.0'
info:
  version: 1.0.0
  title: Based on "Basic Auth Example"
  description: >
    An example for how to use Auth with Swagger.

host: localhost
schemes:
  - http
  - https
paths:
  /:
    get:
      parameters:
        - 
          name: authorization
          in: header
          type: string
          required: true
      responses:
        '200':
          description: 'Will send `Authenticated`'
        '403': 
          description: 'You do not have necessary permissions for the resource'

This will generate a client with a new parameter on method signature:

this.rootGet = function(authorization, callback) {
  // ...
  var headerParams = {
    'authorization': authorization
  };
  // ...
}

To use this method in the right way, just pass the "full string"

// 'token' and 'cb' comes from elsewhere
var header = 'Bearer ' + token;
sdk.rootGet(header, cb);

And works.

Referencing a channel within a conversation

To create a clickable reference to a channel in a Slack conversation, just type # followed by the channel name. For example: #general.

To grab a link to a channel through the Slack UI

To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:

The link would look like this:

https://yourteam.slack.com/messages/C69S1L3SS

Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.

To compose a URL for a channel based on channel name

https://yourteam.slack.com/channels/<channel_name>

Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.

To compose a URL for a direct message (DM) channel to a user

https://yourteam.slack.com/channels/<username>

It is important to note that there was a bug with jailbroken phones on 9.0.x which broke url schemes. If you're running a jailbroken device then make sure you update Patcyh in Cydia

For Spark 1.4.x "Pre built for Hadoop 2.6 and later":

I just copied needed S3, S3native packages from hadoop-aws-2.6.0.jar to spark-assembly-1.4.1-hadoop2.6.0.jar.

After that I restarted spark cluster and it works. Do not forget to check owner and mode of the assembly jar.

Method canOpenUrl is in iOS 9 (due to privacy) changed and is not free to use any more. Your banner provider checks for installed apps so that they do not show banners for an app that is already installed.

That gives all the log statements like

-canOpenURL: failed for URL: "kindle://home" - error: "This app is not allowed to query for scheme kindle"

The providers should update their logic for this.

If you need to query for installed apps/available schemes you need to add them to your info.plist file.

Add the key 'LSApplicationQueriesSchemes' to your plist as an array. Then add strings in that array like 'kindle'.

Of course this is not really an option for the banner ads (since those are dynamic), but you can still query that way for your own apps or specific other apps like Twitter and Facebook.

Documentation of the canOpenUrl: method canOpenUrl:

Documentation about the LSApplicationQueriesSchemes key

If you simply want a Uri for a method that has a route annotation, the following worked for me.

Steps

Get Relative URL

Noting the Route name of the target action, get the relative URL using the controller's URL property as follows:

var routeUrl = Url.RouteUrl("*Route Name Here*", new { *Route parameters here* });

Create an absolute URL

var absUrl = string.Format("{0}://{1}{2}", Request.Scheme,
            Request.Host, routeUrl);

Create a new Uri

var uri = new Uri(absUrl, UriKind.Absolute)

Example

[Produces("application/json")]
[Route("api/Children")]
public class ChildrenController : Controller
{
    private readonly ApplicationDbContext _context;

    public ChildrenController(ApplicationDbContext context)
    {
        _context = context;
    }

    // GET: api/Children
    [HttpGet]
    public IEnumerable<Child> GetChild()
    {
        return _context.Child;
    }

    [HttpGet("uris")]
    public IEnumerable<Uri> GetChildUris()
    {
        return from c in _context.Child
               select
                   new Uri(
                       $"{Request.Scheme}://{Request.Host}{Url.RouteUrl("GetChildRoute", new { id = c.ChildId })}",
                       UriKind.Absolute);
    }


    // GET: api/Children/5
    [HttpGet("{id}", Name = "GetChildRoute")]
    public IActionResult GetChild([FromRoute] int id)
    {
        if (!ModelState.IsValid)
        {
            return HttpBadRequest(ModelState);
        }

        Child child = _context.Child.Single(m => m.ChildId == id);

        if (child == null)
        {
            return HttpNotFound();
        }

        return Ok(child);
    }
}

Create a new style

<!-- Theme.AppCompat.Light.Dialog -->
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">

Java code:

The parent theme is the key here. Choose your colorAccent

DatePickerDialog = new DatePickerDialog(context,R.style.DialogTheme,this,now.get(Calendar.YEAR),now.get(Calendar.MONTH),now.get(Calendar.DAY_OF_MONTH);

Result:

For HttpClient-4.1 using TLSv1.2, code would go something like this:

        SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, new SecureRandom());
        SSLSocketFactory sf = new SSLSocketFactory(sslContext);
        Scheme httpsScheme = new Scheme("https", 443, sf);
        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(httpsScheme);
        ClientConnectionManager cm =  new        SingleClientConnManager(schemeRegistry);
        HttpClient client = new DefaultHttpClient(cm);

       // Use client to make the connection and get the results.

@T0xicCode's answer is correct, but I thought I would expand on the details since it actually took me about 20 hours to finally get a working solution implemented.

If you're looking to run Nginx in its own container and use it as a reverse proxy to load balance multiple applications on the same server instance then the steps you need to follow are as such:

Link Your Containers

When you docker run your containers, typically by inputting a shell script into User Data, you can declare links to any other running containers. This means that you need to start your containers up in order and only the latter containers can link to the former ones. Like so:

#!/bin/bash
sudo docker run -p 3000:3000 --name API mydockerhub/api
sudo docker run -p 3001:3001 --link API:API --name App mydockerhub/app
sudo docker run -p 80:80 -p 443:443 --link API:API --link App:App --name Nginx mydockerhub/nginx

So in this example, the API container isn't linked to any others, but the App container is linked to API and Nginx is linked to both API and App.

The result of this is changes to the env vars and the /etc/hosts files that reside within the API and App containers. The results look like so:

/etc/hosts

Running cat /etc/hosts within your Nginx container will produce the following:

172.17.0.5  0fd9a40ab5ec
127.0.0.1   localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.3  App
172.17.0.2  API

ENV Vars

Running env within your Nginx container will produce the following:

I've truncated many of the actual vars, but the above are the key values you need to proxy traffic to your containers.

To obtain a shell to run the above commands within a running container, use the following:

sudo docker exec -i -t Nginx bash

You can see that you now have both /etc/hosts file entries and env vars that contain the local IP address for any of the containers that were linked. So far as I can tell, this is all that happens when you run containers with link options declared. But you can now use this information to configure nginx within your Nginx container.

Configuring Nginx

This is where it gets a little tricky, and there's a couple of options. You can choose to configure your sites to point to an entry in the /etc/hosts file that docker created, or you can utilize the ENV vars and run a string replacement (I used sed) on your nginx.conf and any other conf files that may be in your /etc/nginx/sites-enabled folder to insert the IP values.

OPTION A: Configure Nginx Using ENV Vars

This is the option that I went with because I couldn't get the /etc/hosts file option to work. I'll be trying Option B soon enough and update this post with any findings.

The key difference between this option and using the /etc/hosts file option is how you write your Dockerfile to use a shell script as the CMD argument, which in turn handles the string replacement to copy the IP values from ENV to your conf file(s).

Here's the set of configuration files I ended up with:

Nginx-Startup.sh

sed -i 's/APP_IP/'"$APP_PORT_3001_TCP_ADDR"'/g' /etc/nginx/sites-enabled/app.myapp.com

service nginx start

I'll leave it up to you to do your homework about most of the contents of nginx.conf and api.myapp.conf.

The magic happens in Nginx-Startup.sh where we use sed to do string replacement on the APP_IP placeholder that we've written into the upstream block of our api.myapp.conf and app.myapp.conf files.

This ask.ubuntu.com question explains it very nicely: Find and replace text within a file using commands

GOTCHA On OSX, sed handles options differently, the -i flag specifically. On Ubuntu, the -i flag will handle the replacement 'in place'; it will open the file, change the text, and then 'save over' the same file. On OSX, the -i flag requires the file extension you'd like the resulting file to have. If you're working with a file that has no extension you must input '' as the value for the -i flag.

GOTCHA To use ENV vars within the regex that sed uses to find the string you want to replace you need to wrap the var within double-quotes. So the correct, albeit wonky-looking, syntax is as above.

So docker has launched our container and triggered the Nginx-Startup.sh script to run, which has used sed to change the value APP_IP to the corresponding ENV variable we provided in the sed command. We now have conf files within our /etc/nginx/sites-enabled directory that have the IP addresses from the ENV vars that docker set when starting up the container. Within your api.myapp.conf file you'll see the upstream block has changed to this:

upstream api_upstream{
    server 172.0.0.2:3000;
}

The IP address you see may be different, but I've noticed that it's usually 172.0.0.x.

You should now have everything routing appropriately.

GOTCHA You cannot restart/rerun any containers once you've run the initial instance launch. Docker provides each container with a new IP upon launch and does not seem to re-use any that its used before. So api.myapp.com will get 172.0.0.2 the first time, but then get 172.0.0.4 the next time. But Nginx will have already set the first IP into its conf files, or in its /etc/hosts file, so it won't be able to determine the new IP for api.myapp.com. The solution to this is likely to use CoreOS and its etcd service which, in my limited understanding, acts like a shared ENV for all machines registered into the same CoreOS cluster. This is the next toy I'm going to play with setting up.

OPTION B: Use /etc/hosts File Entries

This should be the quicker, easier way of doing this, but I couldn't get it to work. Ostensibly you just input the value of the /etc/hosts entry into your api.myapp.conf and app.myapp.conf files, but I couldn't get this method to work.

UPDATE: See @Wes Tod's answer for instructions on how to make this method work.

Here's the attempt that I made in api.myapp.conf:

upstream api_upstream{
    server API:3000;
}

Considering that there's an entry in my /etc/hosts file like so: 172.0.0.2 API I figured it would just pull in the value, but it doesn't seem to be.

I also had a couple of ancillary issues with my Elastic Load Balancer sourcing from all AZ's so that may have been the issue when I tried this route. Instead I had to learn how to handle replacing strings in Linux, so that was fun. I'll give this a try in a while and see how it goes.

This issue is not happening in Firefox and Safari. Make sure you are using the latest version of xml2json.js. Because i faced the XML parser error in IE. In Chrome best way you should open it in server like Apache or XAMPP.

I had the same issue. Sublime3 no longer shows all of the installed packages when you choose Show Packages from the Preferences Menu.

To customise a colour scheme do the following (UNIX):

• Locate your SublimeText packages directory under the directory which SublimeText is installed in (in my setup this was /opt/sublime/Packages)
• Open "Color Scheme - Default.sublime-package"
• Choose the colour scheme which is closest to your requirements and copy it
• From Sublime Text choose Preferences - Browse Packages - User
• Paste the colour scheme you copied earlier here and rename it. It should now show up on your "Preferences - Color Scheme" menu under "User"
• Follow the instructions at the link you previously mentioned to make the changes you require (Sublime 2 -changing background color based on file type?)

--- EDIT ---

For Mac OS X the themes are stored in zipped files so although the preferences file shows them as being in Packages/Color Scheme - Default/ they don't appear in that directory unless you extract them.

• They can be extracted using the Package Resource Viewer (See this answer for how to install and use the Package Resource Viewer).
• Search for Color Scheme in the Package Extractor (should give options for Color Scheme Default and Color Scheme legacy)
• Extract the one you want. It will now be available at users/UserName/Library/Application Support/Sublime Text 3/Packages/Color Scheme - Default (or Legacy)
• Make a copy of the scheme you want to modify, edit as needed and save it
• Add or change the line in user preferences which points to the color scheme

for example

"color_scheme": "Packages/Color Scheme - Legacy/myTheme.tmTheme"

Swift 3.0 & iOS 10+

OK I found the problem, I was checking in the wrong place which is for the whole IDE's look and feel at File->Settings->Appearance

The correct place to change the editor appearance is through File->Settings->Editor->Colors &Fonts and then choose the scheme there. The imported settings appear there :)

Note: The theme site seems to have moved.

I had this issue occurring with mailto: and tel: links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.

Adding target="_blank", as suggested by this discussion of the issue fixed the problem for me.

From Tomcat documentation, For blocking I/O (BIO), the default value of maxConnections is the value of maxThreads unless Executor (thread pool) is used in which case, the value of 'maxThreads' from Executor will be used instead. For Non-blocking IO, it doesn't seem to be dependent on maxThreads.

You can place each image side-by-side by writing the markdown for each image on the same line.

![alt-text-1](image1.png "title-1") ![alt-text-2](image2.png "title-2")

As long as the images aren't too large, they will display inline as demonstrated by this screen shot of a README file from GitHub:

We ended up realising that our one server that was experiencing this had busted fpm config resulting in php errors/warnings/notices that'd normally be logged to disk were being sent over the FCGI socket. It looks like there's a parsing bug when part of the header gets split across the buffer chunks.

So setting php_admin_value[error_log] to something actually writeable and restarting php-fpm was enough to fix the problem.

We could reproduce the problem with a smaller script:

<?php
for ($i = 0; $i<$_GET['iterations']; $i++)
    error_log(str_pad("a", $_GET['size'], "a"));
echo "got here\n";

Raising the buffers made the 502s harder to hit but not impossible, e.g native:

bash-4.1# for it in {30..200..3}; do for size in {100..250..3}; do echo "size=$size iterations=$it $(curl -sv "http://localhost/debug.php?size=$size&iterations=$it" 2>&1 | egrep '^< HTTP')"; done; done | grep 502 | head
size=121 iterations=30 < HTTP/1.1 502 Bad Gateway
size=109 iterations=33 < HTTP/1.1 502 Bad Gateway
size=232 iterations=33 < HTTP/1.1 502 Bad Gateway
size=241 iterations=48 < HTTP/1.1 502 Bad Gateway
size=145 iterations=51 < HTTP/1.1 502 Bad Gateway
size=226 iterations=51 < HTTP/1.1 502 Bad Gateway
size=190 iterations=60 < HTTP/1.1 502 Bad Gateway
size=115 iterations=63 < HTTP/1.1 502 Bad Gateway
size=109 iterations=66 < HTTP/1.1 502 Bad Gateway
size=163 iterations=69 < HTTP/1.1 502 Bad Gateway
[... there would be more here, but I piped through head ...]

fastcgi_buffers 16 16k; fastcgi_buffer_size 32k;:

bash-4.1# for it in {30..200..3}; do for size in {100..250..3}; do echo "size=$size iterations=$it $(curl -sv "http://localhost/debug.php?size=$size&iterations=$it" 2>&1 | egrep '^< HTTP')"; done; done | grep 502 | head
size=223 iterations=69 < HTTP/1.1 502 Bad Gateway
size=184 iterations=165 < HTTP/1.1 502 Bad Gateway
size=151 iterations=198 < HTTP/1.1 502 Bad Gateway

So I believe the correct answer is: fix your fpm config so it logs errors to disk.

In python 3.6.3 with pandas 0.22.0 you can also use concat as long as you set as index the columns you want to use for the joining

pd.concat(
    (iDF.set_index('name') for iDF in [df1, df2, df3]),
    axis=1, join='inner'
).reset_index()

where df1, df2, and df3 are defined as in John Galt's answer

import pandas as pd
df1 = pd.DataFrame(np.array([
    ['a', 5, 9],
    ['b', 4, 61],
    ['c', 24, 9]]),
    columns=['name', 'attr11', 'attr12']
)
df2 = pd.DataFrame(np.array([
    ['a', 5, 19],
    ['b', 14, 16],
    ['c', 4, 9]]),
    columns=['name', 'attr21', 'attr22']
)
df3 = pd.DataFrame(np.array([
    ['a', 15, 49],
    ['b', 4, 36],
    ['c', 14, 9]]),
    columns=['name', 'attr31', 'attr32']
)

One thing i have noticed is that if the tables use different engine than the foreign key constraint does not work.

For example if one table uses:

$table->engine = 'InnoDB';

And the other uses

$table->engine = 'MyISAM';

would generate an error:

SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint

You can fix this by just adding InnoDB at the end of your table creation like so:

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->unsignedInteger('business_unit_id')->nullable();

        $table->string('name', 100);

        $table->foreign('business_unit_id')
                ->references('id')
                ->on('business_units')
                ->onDelete('cascade');

        $table->timestamps();
        $table->softDeletes();
        $table->engine = 'InnoDB'; # <=== see this line
    });
}

You can try using the ModernHttpClient Nuget Package: After downloading the package, you can implement it like this:

 var handler = new ModernHttpClient.NativeMessageHandler()
 {
     UseProxy = true,
 };


 handler.ClientCertificateOptions = ClientCertificateOption.Automatic;
 handler.PreAuthenticate = true;
 HttpClient client = new HttpClient(handler);

I was also facing the same error. The reason for this is that there is no smtp server on your environment. For creating a fake smtp server I used this fake-smtp.jar file for creating a virtual server and listening to all the requests. If you are facing the same error, I recommend you to use this jar and run it after extracting and then try to run your application.

You might get this because of Nginx policy (eg. "deny"), or you might get this because of Nginx misconfiguration, or you might get this because of filesystem restrictions.

You can determine if its the later (and possibly see evidence of a misconfiguration by using strace (except, the OP won't have access to that):

# pidof nginx
11853 11852

# strace -p 11853 -p 11852 -e trace=file -f
Process 11853 attached - interrupt to quit
Process 11852 attached - interrupt to quit
[pid 11853] stat("/var/www/html/kibanaindex.html", 0x7ffe04e93000) = -1 ENOENT (No such file or directory)
[pid 11853] stat("/var/www/html/kibana", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
^CProcess 11853 detached
Process 11852 detached

Here I'm inspecting the filesystem activity done by nginx while a ran a test (I had the same error as you).

Here's a selected part of my config at the time

    location /kibana/3/ {
        alias /var/www/html/kibana;
        index index.html;
    }

In my case, as strace quite clearly shows, the joining of in the "alias" to the "index" was not what I had expected, and it seems I need to get into the habit of always appending directory names with a /, so in my case, the following worked:

    location /kibana/3/ {
        alias /var/www/html/kibana/;
        index index.html;
    }

Using appendEncodePath() could save you multiple lines than appendPath(), the following code snippet builds up this url: http://api.openweathermap.org/data/2.5/forecast/daily?zip=94043

As you can see the old path was written in the compiled.php. So, to fix the problem. Simply run the same command AGAIN under the project folder in your new folder location.

php artisan optimize --force

Hope this helps.

I got the color range to be asymmetric simply by changing the symkey argument to FALSE

symm=F,symkey=F,symbreaks=T, scale="none"

Solved the color issue with colorRampPalette with the breaks argument to specify the range of each color, e.g.

colors = c(seq(-3,-2,length=100),seq(-2,0.5,length=100),seq(0.5,6,length=100))

my_palette <- colorRampPalette(c("red", "black", "green"))(n = 299)

Altogether

heatmap.2(as.matrix(SeqCountTable), col=my_palette, 
    breaks=colors, density.info="none", trace="none", 
        dendrogram=c("row"), symm=F,symkey=F,symbreaks=T, scale="none")

I had this error when I had the current build configuration in Visual Studio set to something other than Debug.

I also came across similar issue. Added core-site.xml and hdfs-site.xml as resources of conf (object)

Configuration conf = new Configuration(true);    
conf.addResource(new Path("<path to>/core-site.xml"));
conf.addResource(new Path("<path to>/hdfs-site.xml"));

Also edited version conflicts in pom.xml. (e.g. If configured version of hadoop is 2.8.1, but in pom.xml file, dependancies has version 2.7.1, then change that to 2.8.1) Run Maven install again.

This solved error for me.

This one worked for me

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

I had the same problem, to solve it set specific user from domain in iis -> action sidebar->Basic Settings -> Connect as... -> specific user

I'll add that arrays are very low-level constructs in C++ and you should try to stay away from them as much as possible when "learning the ropes" -- even Bjarne Stroustrup recommends this (he's the designer of C++).

Vectors come very close to the same performance as arrays, but with a great many conveniences and safety features. You'll probably start using arrays when interfacing with API's that deal with raw arrays, or when building your own collections.

On Linux man ascii says:

ASCII is the American Standard Code for Information Interchange. It is a 7-bit code.

I am using PHP for webservice and Android 4.x. device for connecting to the webservice. I had similar problem where, using 10.0.2.2 worked well with emulator but failed to connect from device. The solution that worked for me is: Find IP of your computer ... say 192.168.0.103 Find the port of your apache ... say 8080 Now open httpd.conf and locate following line Listen 127.0.0.1:8080 After this line add following Listen 192.168.0.103:8080 Thats it. Now if you use 192.168.0.103:8080 in your android code, it will connect!!

You can eliminate the client from the problem by using wftech, this is an old tool but I have found it useful in diagnosing authentication issues. wfetch allows you to specify NTLM, Negotiate and kerberos, this may well help you better understand your problem. As you are trying to call a service and wfetch knows nothing about WCF, I would suggest applying your endpoint binding (PROVIDERSSoapBinding) to the serviceMetadata then you can do an HTTP GET of the WSDL for the service with the same security settings.

Another option, which may be available to you is to force the server to use NTLM, you can do this by either editing the metabase (IIS 6) and removing the Negotiate setting, more details at http://support.microsoft.com/kb/215383.

If you are using IIS 7.x then the approach is slightly different, details of how to configure the authentication providers are here http://www.iis.net/configreference/system.webserver/security/authentication/windowsauthentication.

I notice that you have blocked out the server address with xxx.xx.xx.xxx, so I'm guessing that this is an IP address rather than a server name, this may cause issues with authentication, so if possible try targeting the machine name.

Sorry that I haven't given you the answer but rather pointers for getting closer to the issue, but I hope it helps.

I'll finish by saying that I have experienced this same issue and my only recourse was to use Kerberos rather than NTLM, don't forget you'll need to register an SPN for the service if you do go down this route.

Up to date answer

My fork of sql.js has now be merged into the original version, on kriken's repo.

The good documentation is also available on the original repo.

Original answer (outdated)

You should use the newer version of sql.js. It is a port of sqlite 3.8, has a good documentation and is actively maintained (by me). It supports prepared statements, and BLOB data type.

Set the following CSS properties to the image:

user-drag: none; 
user-select: none;
-moz-user-select: none;
-webkit-user-drag: none;
-webkit-user-select: none;
-ms-user-select: none;

the "file://" url protocol can only be used to locate files in the file system of the local machine. since this html code is interpreted by a browser, the "local machine" is the machine that is running the browser.

if you are getting file not found errors, i suspect it is because the file is not found. however, it could also be a security limitation of the browser. some browsers will not let you reference a filesystem file from a non-filesystem html page. you could try using the file path from the command line on the machine running the browser to confirm that this is a browser limitation and not a legitimate missing file.

The comment states

// Determines what character(s) are used to terminate each line in new files.
// Valid values are 'system' (whatever the OS uses), 'windows' (CRLF) and
// 'unix' (LF only).

You are setting

"default_line_ending": "LF",

You should set

"default_line_ending": "unix",

Have you tried DevDefined.OAuth?

I have used it to secure my WebApi with 2-Legged OAuth. I have also successfully tested it with PHP clients.

It's quite easy to add support for OAuth using this library. Here's how you can implement the provider for ASP.NET MVC Web API:

1) Get the source code of DevDefined.OAuth: https://github.com/bittercoder/DevDefined.OAuth - the newest version allows for OAuthContextBuilder extensibility.

2) Build the library and reference it in your Web API project.

3) Create a custom context builder to support building a context from HttpRequestMessage:

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Diagnostics.CodeAnalysis;
using System.Linq;
using System.Net.Http;
using System.Web;

using DevDefined.OAuth.Framework;

public class WebApiOAuthContextBuilder : OAuthContextBuilder
{
    public WebApiOAuthContextBuilder()
        : base(UriAdjuster)
    {
    }

    public IOAuthContext FromHttpRequest(HttpRequestMessage request)
    {
        var context = new OAuthContext
            {
                RawUri = this.CleanUri(request.RequestUri), 
                Cookies = this.CollectCookies(request), 
                Headers = ExtractHeaders(request), 
                RequestMethod = request.Method.ToString(), 
                QueryParameters = request.GetQueryNameValuePairs()
                    .ToNameValueCollection(), 
            };

        if (request.Content != null)
        {
            var contentResult = request.Content.ReadAsByteArrayAsync();
            context.RawContent = contentResult.Result;

            try
            {
                // the following line can result in a NullReferenceException
                var contentType = 
                    request.Content.Headers.ContentType.MediaType;
                context.RawContentType = contentType;

                if (contentType.ToLower()
                    .Contains("application/x-www-form-urlencoded"))
                {
                    var stringContentResult = request.Content
                        .ReadAsStringAsync();
                    context.FormEncodedParameters = 
                        HttpUtility.ParseQueryString(stringContentResult.Result);
                }
            }
            catch (NullReferenceException)
            {
            }
        }

        this.ParseAuthorizationHeader(context.Headers, context);

        return context;
    }

    protected static NameValueCollection ExtractHeaders(
        HttpRequestMessage request)
    {
        var result = new NameValueCollection();

        foreach (var header in request.Headers)
        {
            var values = header.Value.ToArray();
            var value = string.Empty;

            if (values.Length > 0)
            {
                value = values[0];
            }

            result.Add(header.Key, value);
        }

        return result;
    }

    protected NameValueCollection CollectCookies(
        HttpRequestMessage request)
    {
        IEnumerable<string> values;

        if (!request.Headers.TryGetValues("Set-Cookie", out values))
        {
            return new NameValueCollection();
        }

        var header = values.FirstOrDefault();

        return this.CollectCookiesFromHeaderString(header);
    }

    /// <summary>
    /// Adjust the URI to match the RFC specification (no query string!!).
    /// </summary>
    /// <param name="uri">
    /// The original URI. 
    /// </param>
    /// <returns>
    /// The adjusted URI. 
    /// </returns>
    private static Uri UriAdjuster(Uri uri)
    {
        return
            new Uri(
                string.Format(
                    "{0}://{1}{2}{3}", 
                    uri.Scheme, 
                    uri.Host, 
                    uri.IsDefaultPort ?
                        string.Empty :
                        string.Format(":{0}", uri.Port), 
                    uri.AbsolutePath));
    }
}

4) Use this tutorial for creating an OAuth provider: http://code.google.com/p/devdefined-tools/wiki/OAuthProvider. In the last step (Accessing Protected Resource Example) you can use this code in your AuthorizationFilterAttribute attribute:

public override void OnAuthorization(HttpActionContext actionContext)
{
    // the only change I made is use the custom context builder from step 3:
    OAuthContext context = 
        new WebApiOAuthContextBuilder().FromHttpRequest(actionContext.Request);

    try
    {
        provider.AccessProtectedResourceRequest(context);

        // do nothing here
    }
    catch (OAuthException authEx)
    {
        // the OAuthException's Report property is of the type "OAuthProblemReport", it's ToString()
        // implementation is overloaded to return a problem report string as per
        // the error reporting OAuth extension: http://wiki.oauth.net/ProblemReporting
        actionContext.Response = new HttpResponseMessage(HttpStatusCode.Unauthorized)
            {
               RequestMessage = request, ReasonPhrase = authEx.Report.ToString()
            };
    }
}

I have implemented my own provider so I haven't tested the above code (except of course the WebApiOAuthContextBuilder which I'm using in my provider) but it should work fine.

As an alternative to rendering a raster image, you can embed a SVG file:

<a><img src="http://dump.thecybershadow.net/6c736bfd11ded8cdc5e2bda009a6694a/colortext.svg"/></a>

You can then add color text to the SVG file as usual:

<?xml version="1.0" encoding="utf-8"?>
<svg version="1.1" 
     xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     width="100" height="50"
>
  <text font-size="16" x="10" y="20">
    <tspan fill="red">Hello</tspan>,
    <tspan fill="green">world</tspan>!
  </text>
</svg>

Unfortunately, even though you can select and copy text when you open the .svg file, the text is not selectable when the SVG image is embedded.

Xcode 4.6 will prompt you to reinstall any older versions of the iOS Simulator if you just delete the SDK. To avoid that, you must also delete the Xcode cache. Then you won't be forced to reinstall the older SDK on launch.

To remove the iOS 5.0 simulator, delete these and then restart Xcode:

1. /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/PhoneSimulator5.0.sdk
2. ~/Library/Caches/com.apple.dt.Xcode

For example, after doing a clean install of Xcode, I installed the iOS 5.0 simulator from Xcode preferences. Later, I decided that 5.1 was enough but couldn't remove the 5.0 version. Xcode kept forcing me to reinstall it on launch. After removing both the cache file and the SDK, it no longer asked.

here's the best of both worlds.

I also "like" underscores, besides all your positive points about them, there is also a certain old-school style to them.

So what I do is use underscores and simply add a small rewrite rule to your Apache's .htaccess file to re-write all underscores to hyphens.

https://yoast.com/apache-rewrite-dash-underscore/

First make sure you have installed Nginx with the HTTP rewrite module. To install this we need to have pcre-library

How to install pcre library

If the above mentioned are done or if you already have them, then just add the below code in your nginx server block

  if ($host !~* ^www\.) {
    rewrite ^(.*)$ http://www.$host$1 permanent;
  }

To remove www from every request you can use

  if ($host = 'www.your_domain.com' ) {
   rewrite  ^/(.*)$  http://your_domain.com/$1  permanent;
  }

so your server block will look like

  server {
            listen       80;
            server_name  test.com;
            if ($host !~* ^www\.) {
                    rewrite ^(.*)$ http://www.$host$1 permanent;
            }
            client_max_body_size   10M;
            client_body_buffer_size   128k;

            root       /home/test/test/public;
            passenger_enabled on;
            rails_env production;

            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                    root   html;
            }
    }

Simple Answer: NO. You cannot help ad hoc queries on a 238 column table with a 50% Fill Factor on the Clustered Index.

Detailed Answer:

As I have stated in other answers on this topic, Index design is both Art and Science and there are so many factors to consider that there are few, if any, hard and fast rules. You need to consider: the volume of DML operations vs SELECTs, disk subsystem, other indexes / triggers on the table, distribution of data within the table, are queries using SARGable WHERE conditions, and several other things that I can't even remember right now.

I can say that no help can be given for questions on this topic without an understanding of the Table itself, its indexes, triggers, etc. Now that you have posted the table definition (still waiting on the Indexes but the Table definition alone points to 99% of the issue) I can offer some suggestions.

First, if the table definition is accurate (238 columns, 50% Fill Factor) then you can pretty much ignore the rest of the answers / advice here ;-). Sorry to be less-than-political here, but seriously, it's a wild goose chase without knowing the specifics. And now that we see the table definition it becomes quite a bit clearer as to why a simple query would take so long, even when the test queries (Update #1) ran so quickly.

The main problem here (and in many poor-performance situations) is bad data modeling. 238 columns is not prohibited just like having 999 indexes is not prohibited, but it is also generally not very wise.

Recommendations:

1. First, this table really needs to be remodeled. If this is a data warehouse table then maybe, but if not then these fields really need to be broken up into several tables which can all have the same PK. You would have a master record table and the child tables are just dependent info based on commonly associated attributes and the PK of those tables is the same as the PK of the master table and hence also FK to the master table. There will be a 1-to-1 relationship between master and all child tables.
2. The use of ANSI_PADDING OFF is disturbing, not to mention inconsistent within the table due to the various column additions over time. Not sure if you can fix that now, but ideally you would always have ANSI_PADDING ON, or at the very least have the same setting across all ALTER TABLE statements.
3. Consider creating 2 additional File Groups: Tables and Indexes. It is best not to put your stuff in PRIMARY as that is where SQL SERVER stores all of its data and meta-data about your objects. You create your Table and Clustered Index (as that is the data for the table) on [Tables] and all Non-Clustered indexes on [Indexes]
4. Increase the Fill Factor from 50%. This low number is likely why your index space is larger than your data space. Doing an Index Rebuild will recreate the data pages with a max of 4k (out of the total 8k page size) used for your data so your table is spread out over a wide area.
5. If most or all queries have "ER101_ORG_CODE" in the WHERE condition, then consider moving that to the leading column of the clustered index. Assuming that it is used more often than "ER101_ORD_NBR". If "ER101_ORD_NBR" is used more often then keep it. It just seems, assuming that the field names mean "OrganizationCode" and "OrderNumber", that "OrgCode" is a better grouping that might have multiple "OrderNumbers" within it.
6. Minor point, but if "ER101_ORG_CODE" is always 2 characters, then use CHAR(2) instead of VARCHAR(2) as it will save a byte in the row header which tracks variable width sizes and adds up over millions of rows.
7. As others here have mentioned, using SELECT * will hurt performance. Not only due to it requiring SQL Server to return all columns and hence be more likely to do a Clustered Index Scan regardless of your other indexes, but it also takes SQL Server time to go to the table definition and translate * into all of the column names. It should be slightly faster to specify all 238 column names in the SELECT list though that won't help the Scan issue. But do you ever really need all 238 columns at the same time anyway?

Good luck!

UPDATE
For the sake of completeness to the question "how to improve performance on a large table for ad-hoc queries", it should be noted that while it will not help for this specific case, IF someone is using SQL Server 2012 (or newer when that time comes) and IF the table is not being updated, then using Columnstore Indexes is an option. For more details on that new feature, look here: http://msdn.microsoft.com/en-us/library/gg492088.aspx (I believe these were made to be updateable starting in SQL Server 2014).

UPDATE 2
Additional considerations are:

• Enable compression on the Clustered Index. This option became available in SQL Server 2008, but as an Enterprise Edition-only feature. However, as of SQL Server 2016 SP1, Data Compression was made available in all editions! Please see the MSDN page for Data Compression for details on Row and Page Compression.
• If you cannot use Data Compression, or if it won't provide much benefit for a particular table, then IF you have a column of a fixed-length type (INT, BIGINT, TINYINT, SMALLINT, CHAR, NCHAR, BINARY, DATETIME, SMALLDATETIME, MONEY, etc) and well over 50% of the rows are NULL, then consider enabling the SPARSE option which became available in SQL Server 2008. Please see the MSDN page for Use Sparse Columns for details.

Change

<serviceMetadata httpsGetEnabled="true"/>

to

<serviceMetadata httpsGetEnabled="false"/>

You're telling WCF to use https for the metadata endpoint and I see that your'e exposing your service on http, and then you get the error in the title.

You also have to set <security mode="None" /> if you want to use HTTP as your URL suggests.

This error is because your server doesn't have a valid SSL certificate. Hence we need to tell the client to use a different TrustManager. Here is a sample code:

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {

    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));

client = new DefaultHttpClient(ccm, base.getParams());

In my case i had some problem with opacity transition so this one fix it:

#dropdown {
    transition:.6s opacity;
}
#dropdown.ns {
    opacity:0;
    transition:.6s all;
}
#dropdown.fade {
    opacity:1;
}

Mouse Enter

$('#dropdown').removeClass('ns').addClass('fade');

Mouse Leave

$('#dropdown').addClass('ns').removeClass('fade');

There's a library called Zeta Long Paths that provides a .NET API to work with long paths.

Here's a good article that covers this issue for both .NET and PowerShell: ".NET, PowerShell Path too Long Exception and a .NET PowerShell Robocopy Clone"

Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.

To get the string representation using at least 4 digits:

int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

As of iOS10 you can use

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root")!) 

to open general settings.

also you can add known urls(you can see them in the most upvoted answer) to it to open specific settings. For example the below one opens touchID and passcode.

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=TOUCHID_PASSCODE")!)

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

You can see the list of color schemes under /usr/share/vim/vimNN/colors (with NN being the version, e.g. vim74 for vim 7.4).

This is explained here.

On the linux servers I use via ssh, TAB prints ^I and CTRLd prints ^D.

I've just run into this problem and solved it.

The source of the problem is that you have both XmlAccessType.FIELD and pairs of getters and setters. The solution is to remove setters and add a default constructor and a constructor that takes all fields.

The answer is -flto. You have to pass it to both your compilation and link steps, otherwise it doesn't do anything.

It actually works very well - reduced the size of a microcontroller program I wrote to less than 50% of its previous size!

Unfortunately it did seem a bit buggy - I had instances of things not being built correctly. It may have been due to the build system I'm using (QBS; it's very new), but in any case I'd recommend you only enable it for your final build if possible, and test that build thoroughly.

We can define the so-called foreign key in MongoDB. However, we need to maintain the data integrity BY OURSELVES. For example,

student
{ 
  _id: ObjectId(...),
  name: 'Jane',
  courses: ['bio101', 'bio102']   // <= ids of the courses
}

course
{
  _id: 'bio101',
  name: 'Biology 101',
  description: 'Introduction to biology'
}

The courses field contains _ids of courses. It is easy to define a one-to-many relationship. However, if we want to retrieve the course names of student Jane, we need to perform another operation to retrieve the course document via _id.

If the course bio101 is removed, we need to perform another operation to update the courses field in the student document.

More: MongoDB Schema Design

The document-typed nature of MongoDB supports flexible ways to define relationships. To define a one-to-many relationship:

Embedded document

1. Suitable for one-to-few.
2. Advantage: no need to perform additional queries to another document.
3. Disadvantage: cannot manage the entity of embedded documents individually.

Example:

student
{
  name: 'Kate Monster',
  addresses : [
     { street: '123 Sesame St', city: 'Anytown', cc: 'USA' },
     { street: '123 Avenue Q', city: 'New York', cc: 'USA' }
  ]
}

Child referencing

Like the student/course example above.

Parent referencing

Suitable for one-to-squillions, such as log messages.

host
{
    _id : ObjectID('AAAB'),
    name : 'goofy.example.com',
    ipaddr : '127.66.66.66'
}

logmsg
{
    time : ISODate("2014-03-28T09:42:41.382Z"),
    message : 'cpu is on fire!',
    host: ObjectID('AAAB')       // Reference to the Host document
}

Virtually, a host is the parent of a logmsg. Referencing to the host id saves much space given that the log messages are squillions.

You need to make your regex pattern 'non-greedy' by adding a '?' after the '.+'

By default, '*' and '+' are greedy in that they will match as long a string of chars as possible, ignoring any matches that might occur within the string.

Non-greedy makes the pattern only match the shortest possible match.

See Watch Out for The Greediness! for a better explanation.

Or alternately, change your regex to

\(([^\)]+)\)

which will match any grouping of parens that do not, themselves, contain parens.

This depend on how you want to incorporate it. The scenario 1. click on a link 2. explorer window popped up

<a href="\\server\folder\path" target="_blank">click</a>

If there is a need in a fancy UI - then it will barely serve as a solution.

I put together this test app to reproduce the issue using the HTTP testing framework from the Apache HttpClient package:

ClassLoader cl = HCTest.class.getClassLoader();
URL url = cl.getResource("test.keystore");
KeyStore keystore  = KeyStore.getInstance("jks");
char[] pwd = "nopassword".toCharArray();
keystore.load(url.openStream(), pwd);

TrustManagerFactory tmf = TrustManagerFactory.getInstance(
        TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keystore);
TrustManager[] tm = tmf.getTrustManagers();

KeyManagerFactory kmfactory = KeyManagerFactory.getInstance(
        KeyManagerFactory.getDefaultAlgorithm());
kmfactory.init(keystore, pwd);
KeyManager[] km = kmfactory.getKeyManagers();

SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(km, tm, null);

LocalTestServer localServer = new LocalTestServer(sslcontext);
localServer.registerDefaultHandlers();

localServer.start();
try {

    DefaultHttpClient httpclient = new DefaultHttpClient();
    TrustStrategy trustStrategy = new TrustStrategy() {

        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            for (X509Certificate cert: chain) {
                System.err.println(cert);
            }
            return false;
        }

    };

    SSLSocketFactory sslsf = new SSLSocketFactory("TLS", null, null, keystore, null,
            trustStrategy, new AllowAllHostnameVerifier());
    Scheme https = new Scheme("https", 443, sslsf);
    httpclient.getConnectionManager().getSchemeRegistry().register(https);

    InetSocketAddress address = localServer.getServiceAddress();
    HttpHost target1 = new HttpHost(address.getHostName(), address.getPort(), "https");
    HttpGet httpget1 = new HttpGet("/random/100");
    HttpResponse response1 = httpclient.execute(target1, httpget1);
    System.err.println(response1.getStatusLine());
    HttpEntity entity1 = response1.getEntity();
    EntityUtils.consume(entity1);
    HttpHost target2 = new HttpHost("www.verisign.com", 443, "https");
    HttpGet httpget2 = new HttpGet("/");
    HttpResponse response2 = httpclient.execute(target2, httpget2);
    System.err.println(response2.getStatusLine());
    HttpEntity entity2 = response2.getEntity();
    EntityUtils.consume(entity2);
} finally {
    localServer.stop();
}

Even though, Sun's JSSE implementation appears to always read the trust material from the default trust store for some reason, it does not seem to get added to the SSL context and to impact the process of trust verification during the SSL handshake.

Here's the output of the test app. As you can see, the first request succeeds whereas the second fails as the connection to www.verisign.com is rejected as untrusted.

nginx log format taken from here: http://nginx.org/en/docs/http/ngx_http_log_module.html

no need to install anything extra

worked for me for GET and POST requests:

upstream my_upstream {
   server upstream_ip:upstream_port;
}

location / {
    log_format postdata '$remote_addr - $remote_user [$time_local] '
                       '"$request" $status $bytes_sent '

    access_log /path/to/nginx_access.log postdata;
    proxy_set_header Host $http_host;
    proxy_pass http://my_upstream;
    }
}

just change upstream_ip and upstream_port

1) I had to do the following with my configuration: (Add BackConnectionHostNames or Disable Loopback Check) http://support.microsoft.com/kb/896861

2) I was working off a dev system on an isolated dev network. I had gotten it working using the dev system's computer name in the URL to the web service, but when I modified the URL to the URL that would be used in production (rather than the computer name), I started getting the NTLM error.

3) I noticed the security log showed that the service account failing to login with an error similar to the one in the MSDN article.

4) Adding the BackConnectionHostNames made it so I could log into the server via a browser running on the server, but the service account still had NTLM errors when trying to authenticate for the web services. I wound up disabling the loop back check and that fixed it for me.

I implemented in this form in webview using fragment- inside oncreate:

 webView.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView viewx, String urlx)
                {
     if(Uri.parse(urlx).getHost().endsWith("facebook.com")) {
                        {
                            goToFacebook();
                        }
                        return false;
                    }
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlx));
                    viewx.getContext().startActivity(intent);
                    return true;
                }

});

and outside onCreateView :

 private void goToFacebook() {
        try {
            String facebookUrl = getFacebookPageURL();
            Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
            facebookIntent.setData(Uri.parse(facebookUrl));
            startActivity(facebookIntent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    //facebook url load
    private String getFacebookPageURL() {
        String FACEBOOK_URL = "https://www.facebook.com/pg/XXpagenameXX/";
        String facebookurl = null;

        try {
            PackageManager packageManager = getActivity().getPackageManager();

            if (packageManager != null) {
                Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");

                if (activated != null) {
                    int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;

I like ZenBurn theme, I think it is very mild and appealing for the eye. I had here my own theme's settings JAR file, but I stopped updating it. I still think that theme is very good so I updated this post to a suitable theme with similar colors which is already available on @Yarg's web site

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

Encoding binary data in XML

Suppose you want to embed a couple images within an XML document. The images are binary data, while the XML document is text. But XML cannot handle embedded binary data. So how do you do it?

One option is to encode the images in base64, turning the binary data into text that XML can handle.

Instead of:

<images>
  <image name="Sally">{binary gibberish that breaks XML parsers}</image>
  <image name="Bobby">{binary gibberish that breaks XML parsers}</image>
</images>

you do:

<images>
  <image name="Sally" encoding="base64">j23894uaiAJSD3234kljasjkSD...</image>
  <image name="Bobby" encoding="base64">Ja3k23JKasil3452AsdfjlksKsasKD...</image>
</images>

And the XML parser will be able to parse the XML document correctly and extract the image data.

Found it somewhere long time ago and it works perfectly!

let payload = {
  key: "val",
  key2: "val2"
};

let url = "path/to/api.php";
let form = $('<form>', {'method': 'POST', 'action': url}).hide();
$.each(payload, (k, v) => form.append($('<input>', {'type': 'hidden', 'name': k, 'value': v})) );
$('body').append(form);
form.submit();
form.remove();

Just want to open the app through browser? You can achieve it using below code:

HTML:

<a href="intent:#Intent;action=packageName;category=android.intent.category.DEFAULT;category=android.intent.category.BROWSABLE;end">Click here</a>

Manifest:

<intent-filter>
      <action android:name="packageName" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

This intent filter should be in Launcher Activity.

If you want to pass the data on click of browser link, just refer this link.

1. Install the Visual Studio Color Theme Editor extension:
2. Make your own color scheme or try: The Dark Expression Blend Color Theme (preview below)
3. Once you have that, you'll want schemes for the text editor as well. This site has several, including the VS2012 "dark" theme implemented for VS2010.

You can try too to put this into your ~/.vimrc file:

colorscheme Solarized

There a many answers above but I wasn't able to get any of them working correctly (with my limited time), so for anyone else in the same situation you can try the code below which worked perfectly for my java testing purposes:

    public static HttpClient wrapClient(HttpClient base) {
    try {
        SSLContext ctx = SSLContext.getInstance("TLS");
        X509TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }

            public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };
        ctx.init(null, new TrustManager[]{tm}, null);
        SSLSocketFactory ssf = new SSLSocketFactory(ctx);
        ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        ClientConnectionManager ccm = base.getConnectionManager();
        SchemeRegistry sr = ccm.getSchemeRegistry();
        sr.register(new Scheme("https", ssf, 443));
        return new DefaultHttpClient(ccm, base.getParams());
    } catch (Exception ex) {
        return null;
    }
}

and call like:

DefaultHttpClient baseClient = new DefaultHttpClient();
HttpClient httpClient = wrapClient(baseClient );

If I recall correctly, there are some issues with adding SharePoint web services as a VS2K8 "Service Reference". You need to add it as an old-style "Web Reference" to work properly.

Another alternate approach to Diego's is to use a library:

https://github.com/airbnb/DeepLinkDispatch

You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:

@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
  ...
}

As a plus, the query parameters will also be passed along to the Activity as well.

Adding this as an answer, just since you can't do much fancy formatting in comments.
I had the same issue, except I was creating and binding my web service client entirely in code.
Reason is the DLL was being uploaded into a system, which prohibited the use of config files.

Here is the code as it needed to be updated to communicate over SSL...

Public Function GetWebserviceClient() As WebWorker.workerSoapClient
    Dim binding = New BasicHttpBinding()
    binding.Name = "WebWorkerSoap"
    binding.CloseTimeout = TimeSpan.FromMinutes(1)
    binding.OpenTimeout = TimeSpan.FromMinutes(1)
    binding.ReceiveTimeout = TimeSpan.FromMinutes(10)
    binding.SendTimeout = TimeSpan.FromMinutes(1)

    '// HERE'S THE IMPORTANT BIT FOR SSL
    binding.Security.Mode = BasicHttpSecurityMode.Transport

    Dim endpoint = New EndpointAddress("https://myurl/worker.asmx")

    Return New WebWorker.workerSoapClient(binding, endpoint)
End Function

My Dark Color scheme for QtCreator is at:

Hope it is useful for someone.

encodeURI()/decodeURI and encodeURIComponent()/decodeURIComponent are utility functions to handle this. Read more here https://stackabuse.com/javascripts-encodeuri-function/

My own experience has been that it's best to stick to one of two kinds of assembly references:

• A 'local' assembly in the current build directory
• An assembly in the GAC

I've found (much like you've described) other methods to either be too easily broken or have annoying maintenance requirements.

Any assembly I don't want to GAC, has to live in the execution directory. Any assembly that isn't or can't be in the execution directory I GAC (managed by automatic build events).

This hasn't given me any problems so far. While I'm sure there's a situation where it won't work, the usual answer to any problem has been "oh, just GAC it!". 8 D

Hope that helps!

Yeeeaaahhh.... you can now use var() function in CSS.....

The good news is you can change it using JavaScript access, which will change globally as well...

But how to declare them...

It's quite simple:

For example, you wanna assign a #ff0000 to a var(), just simply assign it in :root, also pay attention to --:

:root {
    --red: #ff0000;

The good things are the browser support is not bad, also don't need to be compiled to be used in the browser like LESS or SASS...

Also, here is a simple JavaScript script, which changes the red value to blue:

const rootEl = document.querySelector(':root');
root.style.setProperty('--red', 'blue');

you can do these line on your mysql query browser or something

SET old_passwords = 0;
UPDATE mysql.user SET Password = PASSWORD('testpass') WHERE User = 'testuser' limit 1;
SELECT LENGTH(Password) FROM mysql.user WHERE User = 'testuser';
FLUSH PRIVILEGES;

note:your username and password

after that it should able to work. I just solved mine too

I would recommend Ulrich Drepper's SHA-256/SHA-512 based crypt implementation.

We ported these algorithms to Java, and you can find a freely licensed version of them at ftp://ftp.arlut.utexas.edu/java_hashes/.

Note that most modern (L)Unices support Drepper's algorithm in their /etc/shadow files.

Security researchers Jean-Baptiste Bédrune and Jean Sigwald presented how to do this at Hack-in-the-box Amsterdam 2011.

Since then, Apple has released an iOS Security Whitepaper with more details about keys and algorithms, and Charlie Miller et al. have released the iOS Hacker’s Handbook, which covers some of the same ground in a how-to fashion. When iOS 10 first came out there were changes to the backup format which Apple did not publicize at first, but various people reverse-engineered the format changes.

Encrypted backups are great

The great thing about encrypted iPhone backups is that they contain things like WiFi passwords that aren’t in regular unencrypted backups. As discussed in the iOS Security Whitepaper, encrypted backups are considered more “secure,” so Apple considers it ok to include more sensitive information in them.

An important warning: obviously, decrypting your iOS device’s backup removes its encryption. To protect your privacy and security, you should only run these scripts on a machine with full-disk encryption. While it is possible for a security expert to write software that protects keys in memory, e.g. by using functions like VirtualLock() and SecureZeroMemory() among many other things, these Python scripts will store your encryption keys and passwords in strings to be garbage-collected by Python. This means your secret keys and passwords will live in RAM for a while, from whence they will leak into your swap file and onto your disk, where an adversary can recover them. This completely defeats the point of having an encrypted backup.

How to decrypt backups: in theory

The iOS Security Whitepaper explains the fundamental concepts of per-file keys, protection classes, protection class keys, and keybags better than I can. If you’re not already familiar with these, take a few minutes to read the relevant parts.

Now you know that every file in iOS is encrypted with its own random per-file encryption key, belongs to a protection class, and the per-file encryption keys are stored in the filesystem metadata, wrapped in the protection class key.

To decrypt:

1. Decode the keybag stored in the BackupKeyBag entry of Manifest.plist. A high-level overview of this structure is given in the whitepaper. The iPhone Wiki describes the binary format: a 4-byte string type field, a 4-byte big-endian length field, and then the value itself.

   The important values are the PBKDF2 ITERations and SALT, the double protection salt DPSL and iteration count DPIC, and then for each protection CLS, the WPKY wrapped key.

2. Using the backup password derive a 32-byte key using the correct PBKDF2 salt and number of iterations. First use a SHA256 round with DPSL and DPIC, then a SHA1 round with ITER and SALT.

   Unwrap each wrapped key according to RFC 3394.

3. Decrypt the manifest database by pulling the 4-byte protection class and longer key from the ManifestKey in Manifest.plist, and unwrapping it. You now have a SQLite database with all file metadata.

4. For each file of interest, get the class-encrypted per-file encryption key and protection class code by looking in the Files.file database column for a binary plist containing EncryptionKey and ProtectionClass entries. Strip the initial four-byte length tag from EncryptionKey before using.

   Then, derive the final decryption key by unwrapping it with the class key that was unwrapped with the backup password. Then decrypt the file using AES in CBC mode with a zero IV.

How to decrypt backups: in practice

First you’ll need some library dependencies. If you’re on a mac using a homebrew-installed Python 2.7 or 3.7, you can install the dependencies with:

CFLAGS="-I$(brew --prefix)/opt/openssl/include" \
LDFLAGS="-L$(brew --prefix)/opt/openssl/lib" \    
    pip install biplist fastpbkdf2 pycrypto

In runnable source code form, here is how to decrypt a single preferences file from an encrypted iPhone backup:

The iphone-dataprotection code posted by Bédrune and Sigwald can decrypt the keychain from a backup, including fun things like saved wifi and website passwords:

$ python iphone-dataprotection/python_scripts/keychain_tool.py ...

That code no longer works on backups from phones using the latest iOS, but there are some golang ports that have been kept up to date allowing access to the keychain.

You could use a regular expression such as the following:

/([-a-z0-9]+)\s*\((.*?)\)\s*(\*)?/

So for example:

$s = "abc-456-hu5t10 (High priority) *";
$s =~ /([-a-z0-9]+)\s*\((.*?)\)\s*(\*)?/;
print "$1\n$2\n$3\n";

prints

abc-456-hu5t10
High priority
*

To format all the code in NetBeans, press Alt + Shift + F. If you want to indent lines, select the lines and press Alt + Shift + right arrow key, and to unindent, press Alt + Shift + left arrow key.

I used tel: for my project.

It worked in Chrome, Firefox, IE9&8, Chrome mobile and the mobile Browser on my Sony Ericsson smartphone.

But callto: did not work in the mobile Browsers.

You can't, as far as I know, make the entire OS understand an http:+domain URL. You can only register new schemes (I use x-darkslide: in my app). If the app is installed, Mobile Safari will launch the app correctly.

However, you would have to handle the case where the app isn't installed with a "Still here? Click this link to download the app from iTunes." in your web page.

I see this isn't answered yet, this is an exact quote from here:

WSHttpBinding will try and perform an internal negotiate at the SSP layer. In order for this to be successful, you will need to allow anonymous in IIS for the VDir. WCF will then by default perfrom an SPNEGO for window credentials. Allowing anonymous at IIS layer is not allowing anyone in, it is deferring to the WCF stack.

I found this via: http://fczaja.blogspot.com/2009/10/http-request-is-unauthorized-with.html

After googling: http://www.google.tt/#hl=en&source=hp&q=+The+HTTP+request+is+unauthorized+with+client+authentication+scheme+%27Anonymous

use encodeURIComponent function to fix url, it works on Browser and node.js

res.redirect("/signin?email="+encodeURIComponent("[email protected]"));

The 320 implementations are so much better - here is a patch to get consistent start/ends of the scroll.

-(void)scrollViewDidScroll:(UIScrollView *)sender 
{   
[NSObject cancelPreviousPerformRequestsWithTarget:self];
    //ensure that the end of scroll is fired.
    [self performSelector:@selector(scrollViewDidEndScrollingAnimation:) withObject:sender afterDelay:0.3]; 

...
}

-(void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView
{
    [NSObject cancelPreviousPerformRequestsWithTarget:self];
...
}

Note that increasing a browser's max connections per server to an excessive number (as some sites suggest) can and does lock other users out of small sites with hosting plans that limit the total simultaneous connections on the server.

The worst language? BancStar, hands down.

3,000 predefined variables, all numbered, all global. No variable declaration, no initialization. Half of them, scattered over the range, reserved for system use, but you can use them at your peril. A hundred or so are automatically filled in as a result of various operations, and no list of which ones those are. They all fit in 38k bytes, and there is no protection whatsoever for buffer overflow. The system will cheerfully let users put 20 bytes in a ten byte field if you declared the length of an input field incorrectly. The effects are unpredictable, to say the least.

This is a language that will let you declare a calculated gosub or goto; due to its limitations, this is frequently necessary. Conditionals can be declared forward or reverse. Picture an "If" statement that terminates 20 lines before it begins.

The return stack is very shallow, (20 Gosubs or so) and since a user's press of any function key kicks off a different subroutine, you can overrun the stack easily. The designers thoughtfully included a "Clear Gosubs" command to nuke the stack completely in order to fix that problem and to make sure you would never know exactly what the program would do next.

There is much more. Tens of thousands of lines of this Lovecraftian horror.

IRIs do not replace URIs, because only URIs (effectively, ASCII) are permissible in some contexts -- including HTTP.

Instead, you specify an IRI and it gets transformed into a URI when going out on the wire.

Here's a flow chart that illustrates a for loop:

The equivalent C code would be

for(i = 2; i <= 6; i = i + 2) {
    printf("%d\t", i + 1);
}

I found this and several other examples on one of Tenouk's C Laboratory practice worksheets.

Only the first base address in the list will be taken over (coming from IIS). You can't have multiple base addresses per scheme prior to .NET4.

I think your co-worker is smart and you are also correct.

The useful things I found that putting everything into the headers is that:

1. No need for writing & sync headers and sources.

2. The structure is plain and no circular dependencies force the coder to make a "better" structure.

3. Portable, easy to embedded to a new project.

I do agree with the compiling time problem, but I think we should notice that:

1. The change of source file are very likely to change the header files which leads to the whole project be recompiled again.

2. Compiling speed is much faster than before. And if you have a project to be built with a long time and high frequency, it may indicates that your project design has flaws. Seperate the tasks into different projects and module can avoid this problem.

Lastly I just wanna support your co-worker, just in my personal view.

And in my case it was simple: I used 'Add WCF Service' wizard in Visual Studio, which automatically created corresponding sections in app.config. Then I went on reading How to: Host a WCF Service in a Managed Application. The problem was: I didn't need to specify the url to run the web service.

Replace:

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))

With:

using (ServiceHost host = new ServiceHost(typeof(HelloWorldService))

And the error is gone.

Generic idea: if you provide base address as a param and specify it in config, you get this error. Most probably, that's not the only way to get the error, thou.

In SQL Server 2000, objects created were linked to that particular user, like if a user, say Sam creates an object, say, Employees, that table would appear like: Sam.Employees. What about if Sam is leaving the compnay or moves to so other business area. As soon you delete the user Sam, what would happen to Sam.Employees table? Probably, you would have to change the ownership first from Sam.Employees to dbo.Employess. Schema provides a solution to overcome this problem. Sam can create all his object within a schemam such as Emp_Schema. Now, if he creates an object Employees within Emp_Schema then the object would be referred to as Emp_Schema.Employees. Even if the user account Sam needs to be deleted, the schema would not be affected.

To produce the same results:

MessageDigest sha1 = MessageDigest.getInstance("SHA1", BOUNCY_CASTLE_PROVIDER);
byte[] digest = sha1.digest(content);
DERObjectIdentifier sha1oid_ = new DERObjectIdentifier("1.3.14.3.2.26");

AlgorithmIdentifier sha1aid_ = new AlgorithmIdentifier(sha1oid_, null);
DigestInfo di = new DigestInfo(sha1aid_, digest);

byte[] plainSig = di.getDEREncoded();
Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding", BOUNCY_CASTLE_PROVIDER);
cipher.init(Cipher.ENCRYPT_MODE, privateKey);
byte[] signature = cipher.doFinal(plainSig);

Or you could use the known solution to this problem and use SSL. Self-signed certs are free and its a personal project right?

This worked for me perfectly using only APP ID:

 NSString *urlString = [NSString stringWithFormat:@"http://itunes.apple.com/app/id%@",YOUR_APP_ID];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

The number of redirects is ZERO.

I was using webHttpBinding and forgot to dicate the security mode of "Transport" on the binding configuration which caused the error:

  <webHttpBinding>
    <binding name="MyWCFServiceEndpoint">
      <security mode="Transport" />
    </binding>
  </webHttpBinding>

Adding this in configuration fixed the problem.

You can try grabbing the cssText and className.

var css1 = table.rows[1].style.cssText;
var css2 = table.rows[2].style.cssText;
var class1 = table.rows[1].className;
var class2 = table.rows[2].className;

// sort

// loop
    if (i%2==0) {
        table.rows[i].style.cssText = css1;
        table.rows[i].className = class1;
    } else {
        table.rows[i].style.cssText = css2;
        table.rows[i].className = class2;
    }

Not entirely sure about browser compatibility with cssText, though.

First of all, I assume you want linked lists. In practice, you can use collections.deque, whose current CPython implementation is a doubly linked list of blocks (each block contains an array of 62 cargo objects). It subsumes linked list's functionality. You can also search for a C extension called llist on pypi. If you want a pure-Python and easy-to-follow implementation of the linked list ADT, you can take a look at my following minimal implementation.

class Node (object):
    """ Node for a linked list. """
    def __init__ (self, value, next=None):
        self.value = value
        self.next = next

class LinkedList (object):
    """ Linked list ADT implementation using class. 
        A linked list is a wrapper of a head pointer
        that references either None, or a node that contains 
        a reference to a linked list.
    """
    def __init__ (self, iterable=()):
        self.head = None
        for x in iterable:
            self.head = Node(x, self.head)

    def __iter__ (self):
        p = self.head
        while p is not None:
            yield p.value
            p = p.next

    def prepend (self, x):  # 'appendleft'
        self.head = Node(x, self.head)

    def reverse (self):
        """ In-place reversal. """
        p = self.head
        self.head = None
        while p is not None:
            p0, p = p, p.next
            p0.next = self.head
            self.head = p0

if __name__ == '__main__':
    ll = LinkedList([6,5,4])
    ll.prepend(3); ll.prepend(2)
    print list(ll)
    ll.reverse()
    print list(ll)

Swift 5.2 Xcode 11.4

The Apple Symbol chevron.left now allows a more elegant solution to make a custom button. I have matched the size and spacing as close as possible.

import UIKit

class CustomBackButton: UIBarButtonItem {

    convenience init(target: Any, selector: Selector) {

        // Create UIButton
        let button = UIButton(frame: .zero)

        // Customise Title
        button.setTitle("Back", for: .normal)
        button.setTitleColor(.systemBlue, for: .normal)
        button.titleLabel?.font = UIFont.systemFont(ofSize: 17)

        // Customise Image
        let config = UIImage.SymbolConfiguration(pointSize: 19.0, weight: .semibold, scale: .large)
        let image = UIImage(systemName: "chevron.left", withConfiguration: config)
        button.setImage(image, for: .normal)

        // Add Target
        button.addTarget(target, action: selector, for: .touchUpInside)

        // Customise Spacing to match system Back button
        button.imageEdgeInsets = UIEdgeInsets(top: 0.0, left: -18.0, bottom: 0.0, right: 0.0)
        button.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -12.0, bottom: 0.0, right: 0.0)

        self.init(customView: button)
    }
}

This can be implemented either as a UIToolbarItem, or a UINavigationItem

override func viewDidLoad() {
    super.viewDidLoad()

    // UIToolbar Item
    let barBackButton = CustomBackButton(target: self, selector: #selector(backButtonTapped))
    let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
    navigationController?.setToolbarHidden(false, animated: false)
    toolbarItems = [barBackButton, flexSpace]

    // Navigation Item
    let navBackButton = CustomBackButton(target: self, selector: #selector(backButtonTapped))
    navigationItem.leftBarButtonItem = navBackButton
}

@objc func backButtonTapped() {
    print("Back tapped")
}

If you want to flip the button and have the arrow pointing to the Right:

Use Apple Symbol named "chevron.right"

Add the following code to the CustomBackButton class:

    // Put the image of the right side of the button
    button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
    button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
    button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)

If you aren't referencing your FK's that often and using MySQL (and InnoDB) then you can just let MySQL name the FK for you.

At a later time you can find the FK name you need by running a query.

Easiest way: change the Windows Display Properties main window background color. I went to Appearance tab, changed to Silver scheme, clicked Advanced, clicked on "Active Window" and changed Color 1 to a light gray. All Eclipse views softened.

Since Luna (4.4) there seems to be a full Dark them in

Window -> Preferences -> General -> Appearance -> Theme -> Dark

Given the following function

function person(name, age){

    var name = name;
    var age = age;

    function introduce(){
        alert("My name is "+name+", and I'm "+age);
    }

    return introduce;
}

var a = person("Jack",12);
var b = person("Matt",14);

Everytime the function person is called a new closure is created. While variables a and b have the same introduce function, it is linked to different closures. And that closure will still exist even after the function person finishes execution.

a(); //My name is Jack, and I'm 12
b(); //My name is Matt, and I'm 14

An abstract closures could be represented to something like this:

closure a = {
    name: "Jack",
    age: 12,
    call: function introduce(){
        alert("My name is "+name+", and I'm "+age);
    }
}

closure b = {
    name: "Matt",
    age: 14,
    call: function introduce(){
        alert("My name is "+name+", and I'm "+age);
    }
}

Assuming you know how a class in another language work, I will make an analogy.

Think like

• JavaScript function as a constructor
• local variables as instance properties
• these properties are private
• inner functions as instance methods

Everytime a function is called

• A new object containing all local variables will be created.
• Methods of this object have access to "properties" of that instance object.

The following document linked from the draft RFC mentioned by Jim in his answer further addresses the question and definitely worth a direct note here:

Test Cases for HTTP Content-Disposition header and RFC 2231/2047 Encoding

For Java EE 5 there's a separate tutorial JEE tutorial. That's useful, as people often ask about persistence and xml binding in java.

It does it:

myString.substr(-1);

This returns a substring of myString starting at one character from the end: the last character.

This also works:

myString.charAt(myString.length-1);

And this too:

myString.slice(-1);

You need to return a view which has a friendly error message to the user

catch (Exception ex)
{
   // to do :log error
   return View("Error");
}

You should not be showing the internal details of your exception(like exception stacktrace etc) to the user. You should be logging the relevant information to your error log so that you can go through it and fix the issue.

If your request is an ajax request, You may return a JSON response with a proper status flag which client can evaluate and do further actions

[HttpPost]
public ActionResult Create(CustomerVM model)
{
  try
  {
   //save customer
    return Json(new { status="success",message="customer created"});
  }
  catch(Exception ex)
  {
    //to do: log error
   return Json(new { status="error",message="error creating customer"});
  }
} 

If you want to show the error in the form user submitted, You may use ModelState.AddModelError method along with the Html helper methods like Html.ValidationSummary etc to show the error to the user in the form he submitted.

As string data types have variable length, it is by default stored as object type. I faced this problem after treating missing values too. Converting all those columns to type 'category' before label encoding worked in my case.

df[cat]=df[cat].astype('category')

And then check df.dtypes and perform label encoding.

You could also just put the first SELECT in a subquery. Since most optimizers will fold it into a constant anyway, there should not be a performance hit on this.

Incidentally, since you are using a predicate like this:

CONVERT(...) = CONVERT(...)

that predicate expression cannot be optimized properly or use indexes on the columns reference by the CONVERT() function.

Here is one way to make the original query somewhat better:

DECLARE @ooDate datetime
SELECT @ooDate = OO.Date FROM OLAP.OutageHours AS OO where OO.OutageID = 1

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  FF.FaultDate >= @ooDate AND
  FF.FaultDate < DATEADD(day, 1, @ooDate) AND
  OFIO.OutageID = 1

This version could leverage in index that involved FaultDate, and achieves the same goal.

Here it is, rewritten to use a subquery to avoid the variable declaration and subsequent SELECT.

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  CONVERT(varchar(10), FF.FaultDate, 126) = (SELECT CONVERT(varchar(10), OO.Date, 126) FROM OLAP.OutageHours AS OO where OO.OutageID = 1) AND
  OFIO.OutageID = 1

Note that this approach has the same index usage issue as the original, because of the use of CONVERT() on FF.FaultDate. This could be remedied by adding the subquery twice, but you would be better served with the variable approach in this case. This last version is only for demonstration.

Regards.

Calendar has a set() method that can set the year, month, and day-of-month in one call:

myCal.set( theYear, theMonth, theDay );

I would check the DDL for the sequence in the schema. JPA Implementation is responsible only creation of the sequence with the correct allocation size. Therefore, if the allocation size is 50 then your sequence must have the increment of 50 in its DDL.

This case may typically occur with the creation of a sequence with allocation size 1 then later configured to allocation size 50 (or default) but the sequence DDL is not updated.

I think you are looking for this

git reset --soft HEAD~1

It undoes the most recent commit whilst keeping the changes made in that commit to staging.

Dialog Fragment is the simplest way of creating a custom Alert Dialog.Follow the above code to create a custom view for your dialog and then implement it using Dialog Fragment. Add the following code to your layout file:

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold" />


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

Iv'e noticed this recently with all new macs here at my office. Atom will be installed via an image for the developers but we found the Atom is never in the Application folder.

When doing a ls on the /usr/local/bin folder the path for atom will show something like "/private/var/folders/cs" . To resolve this, we just located atom.app and copied it into the application folder, then ran the system link commands provided by nwinkler which resoled the issue. Developers can now open atom from the command line with "atom" or open the current projects from their working director with "atom ."

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

When you want one element placed at the bottom other element you use this code in CSS. It is used for floats.

If you float content you can float left or right... so in a common layout you might have a left nav, a content div and a footer.

To ensure the footer stays below both of these floats (if you have floated left and right) then you put the footer as clear: both.

This way it will stay below both floats.

(If you are only clearing left then you only really need to clear: left;.)

Go through this tutorial:

You can add the following in your .bashrc

if [ "$TERM" = xterm ]; then TERM=xterm-256color; fi

I've quickly resolved this issue by upgrading gradle (Android Studio seems to use old version).

1) Download latest version (https://gradle.org/gradle-download/) and unpack somewhere.
2) Update path in Android Studio: File > Settings > Build, Ex../Gradle

Try:

colnames(x)[2] <- 'newname2'

:set list to enable.

:set nolist to disable.

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

From Database.
Blob blob = resultSet.getBlob("pictureBlob");               
byte [] data = blob.getBytes( 1, ( int ) blob.length() );
BufferedImage img = null;
try {
img = ImageIO.read(new ByteArrayInputStream(data));
} catch (IOException e) {
    e.printStackTrace();
}
drawPicture(img);  //  void drawPicture(Image img);

These examples are fine, I wanted to point out that you can achieve the same result using an Intent. The intent opens the Contacts app with the fields you provide already filled in.

It's up to the user to save the newly created contact.

You can read about it here: https://developer.android.com/training/contacts-provider/modify-data.html

Intent contactIntent = new Intent(ContactsContract.Intents.Insert.ACTION);
contactIntent.setType(ContactsContract.RawContacts.CONTENT_TYPE);

contactIntent
        .putExtra(ContactsContract.Intents.Insert.NAME, "Contact Name")
        .putExtra(ContactsContract.Intents.Insert.PHONE, "5555555555");

startActivityForResult(contactIntent, 1);

startActivityForResult() gives you the opportunity to see the result.

I've noticed the resultCode works on >5.0 devices,

but I have an older Samsung (<5) that always returns RESULT_CANCELLED (0).

Which I understand is the default return if an activity doesn't expect to return anything.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == 1)
    {
        if (resultCode == Activity.RESULT_OK) {
            Toast.makeText(this, "Added Contact", Toast.LENGTH_SHORT).show();
        }
        if (resultCode == Activity.RESULT_CANCELED) {
            Toast.makeText(this, "Cancelled Added Contact", Toast.LENGTH_SHORT).show();
        }
    }
}

I created my own solution for converting int to Hex string and back before I found this answer. Not surprisingly, it's considerably faster than the .net solution since there's less code overhead.

        /// <summary>
        /// Convert an integer to a string of hexidecimal numbers.
        /// </summary>
        /// <param name="n">The int to convert to Hex representation</param>
        /// <param name="len">number of digits in the hex string. Pads with leading zeros.</param>
        /// <returns></returns>
        private static String IntToHexString(int n, int len)
        {
            char[] ch = new char[len--];
            for (int i = len; i >= 0; i--)
            {
                ch[len - i] = ByteToHexChar((byte)((uint)(n >> 4 * i) & 15));
            }
            return new String(ch);
        }

        /// <summary>
        /// Convert a byte to a hexidecimal char
        /// </summary>
        /// <param name="b"></param>
        /// <returns></returns>
        private static char ByteToHexChar(byte b)
        {
            if (b < 0 || b > 15)
                throw new Exception("IntToHexChar: input out of range for Hex value");
            return b < 10 ? (char)(b + 48) : (char)(b + 55);
        }

        /// <summary>

        private static int HexStringToInt(String str)
        {
            int value = 0;
            for (int i = 0; i < str.Length; i++)
            {
                value += HexCharToInt(str[i]) << ((str.Length - 1 - i) * 4);
            }
            return value;
        }

        /// <summary>

        /// </summary>
        /// <param name="ch"></param>
        /// <returns></returns>
        private static int HexCharToInt(char ch)
        {
            if (ch < 48 || (ch > 57 && ch < 65) || ch > 70)
                throw new Exception("HexCharToInt: input out of range for Hex value");
            return (ch < 58) ? ch - 48 : ch - 55;
        }

Timing code:

        {
            int num = 3500;
            long start = System.Diagnostics.Stopwatch.GetTimestamp();
            for (int i = 0; i < 2000000; i++)
                if (num != HexStringToInt(IntToHexString(num, 3)))
                    Console.WriteLine(num + " = " + HexStringToInt(IntToHexString(num, 3)));
            long end = System.Diagnostics.Stopwatch.GetTimestamp();
            Console.WriteLine(((double)end - (double)start)/(double)System.Diagnostics.Stopwatch.Frequency);

            for (int i = 0; i < 2000000; i++)
                if (num != Convert.ToInt32(num.ToString("X3"), 16))
                    Console.WriteLine(i);
            end = System.Diagnostics.Stopwatch.GetTimestamp();
            Console.WriteLine(((double)end - (double)start)/(double)System.Diagnostics.Stopwatch.Frequency);

The method array.toString() actually calls array.join() which result in a string concatenated by commas. ref

var array = ['a','b','c','d','e','f'];_x000D_
document.write(array.toString()); // "a,b,c,d,e,f"

Also, you can implicitly call Array.toString() by making javascript coerce the Array to an string, like:

//will implicitly call array.toString()
str = ""+array;
str = `${array}`;

Array.prototype.join()

The join() method joins all elements of an array into a string.

Arguments:

It accepts a separator as argument, but the default is already a comma ,

str = arr.join([separator = ','])

Examples:

var array = ['A', 'B', 'C'];
var myVar1 = array.join();      // 'A,B,C'
var myVar2 = array.join(', ');  // 'A, B, C'
var myVar3 = array.join(' + '); // 'A + B + C'
var myVar4 = array.join('');    // 'ABC'

Note:

If any element of the array is undefined or null , it is treated as an empty string.

Browser support:

It is available pretty much everywhere today, since IE 5.5 (1999~2000).

As a general rule (i.e. in vanilla kernels), fork/clone failures with ENOMEM occur specifically because of either an honest to God out-of-memory condition (dup_mm, dup_task_struct, alloc_pid, mpol_dup, mm_init etc. croak), or because security_vm_enough_memory_mm failed you while enforcing the overcommit policy.

Start by checking the vmsize of the process that failed to fork, at the time of the fork attempt, and then compare to the amount of free memory (physical and swap) as it relates to the overcommit policy (plug the numbers in.)

In your particular case, note that Virtuozzo has additional checks in overcommit enforcement. Moreover, I'm not sure how much control you truly have, from within your container, over swap and overcommit configuration (in order to influence the outcome of the enforcement.)

Now, in order to actually move forward I'd say you're left with two options:

• switch to a larger instance, or
• put some coding effort into more effectively controlling your script's memory footprint

NOTE that the coding effort may be all for naught if it turns out that it's not you, but some other guy collocated in a different instance on the same server as you running amock.

Memory-wise, we already know that subprocess.Popen uses fork/clone under the hood, meaning that every time you call it you're requesting once more as much memory as Python is already eating up, i.e. in the hundreds of additional MB, all in order to then exec a puny 10kB executable such as free or ps. In the case of an unfavourable overcommit policy, you'll soon see ENOMEM.

Alternatives to fork that do not have this parent page tables etc. copy problem are vfork and posix_spawn. But if you do not feel like rewriting chunks of subprocess.Popen in terms of vfork/posix_spawn, consider using suprocess.Popen only once, at the beginning of your script (when Python's memory footprint is minimal), to spawn a shell script that then runs free/ps/sleep and whatever else in a loop parallel to your script; poll the script's output or read it synchronously, possibly from a separate thread if you have other stuff to take care of asynchronously -- do your data crunching in Python but leave the forking to the subordinate process.

HOWEVER, in your particular case you can skip invoking ps and free altogether; that information is readily available to you in Python directly from procfs, whether you choose to access it yourself or via existing libraries and/or packages. If ps and free were the only utilities you were running, then you can do away with subprocess.Popen completely.

Finally, whatever you do as far as subprocess.Popen is concerned, if your script leaks memory you will still hit the wall eventually. Keep an eye on it, and check for memory leaks.

while using Header array

String auth = Base64.getEncoder().encodeToString(("test1:test1").getBytes());
Header[] headers = {
    new BasicHeader(HTTP.CONTENT_TYPE, ContentType.APPLICATION_JSON.toString()),

Laravel [5.4]

My solution was to use global session helper: session()

Its functionality is a little bit harder than $request->session().

writing:

session(['key'=>'value']);

pushing:

session()->push('key', $notification);

retrieving:

session('key');

Looks like moment.js is the most popular and with active development:

moment("2010-01-01T05:06:07", moment.ISO_8601);

number = parseInt(number);

That should do the trick.

Try this: (For Preview)

<script type="text/javascript">
    function readURL(input) {
        if (input.files && input.files[0]) {
            var reader = new FileReader();

            reader.onload = function (e) {
                $('#blah').attr('src', e.target.result);
            }

            reader.readAsDataURL(input.files[0]);
        }
    }
</script>

<body>
    <form id="form1" runat="server">
        <input type="file" onchange="readURL(this);" />
        <img id="blah" src="#" alt="your image" />
    </form>
</body>

Working Demo here>

See if this helps:

[Serializable()]
[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)]
public class Cars
{
    [XmlArrayItem(typeof(Car))]
    public Car[] Car { get; set; }
}

.

[Serializable()]
public class Car
{
    [System.Xml.Serialization.XmlElement()]
    public string StockNumber{ get; set; }

    [System.Xml.Serialization.XmlElement()]
    public string Make{ get; set; }

    [System.Xml.Serialization.XmlElement()]
    public string Model{ get; set; }
}

And failing that use the xsd.exe program that comes with visual studio to create a schema document based on that xml file, and then use it again to create a class based on the schema document.

If all of that did not work try this.

with open("hello.txt") as f:
with open("copy.txt", "w") as f1:
    for line in f:
        f1.write(line)

select 1 would work in sql server, not sure about the others.

Use standard ansi sql to create a table and then query from that table.

The problem of using Application.Restart() is, that it starts a new process but the "old" one is still remaining. Therefor I decided to Kill the old process by using the following code snippet:

            if(Condition){
            Application.Restart();
            Process.GetCurrentProcess().Kill();
            }

And it works proper good. In my case MATLAB and a C# Application are sharing the same SQLite database. If MATLAB is using the database, the Form-App should restart (+Countdown) again, until MATLAB reset its busy bit in the database. (Just for side information)

For the sake of completeness, first make sure you have the correct import so you can use the addRow function:

import javax.swing.table.*;

Assuming your jTable is already created, you can proceed and create your own add row method which will accept the parameters that you need:

public void yourAddRow(String str1, String str2, String str3){
  DefaultTableModel yourModel = (DefaultTableModel) yourJTable.getModel();
  yourModel.addRow(new Object[]{str1, str2, str3});
}

Simple fundamentals, Elastic community has exposed indexing, searching, deleting operation as rest web service. You can interact elastic using curl or sense(chrome plugin) or any rest client like postman.

If you are just testing few commands, I would recommend can use of sense chrome plugin which has simple UI and pretty mature plugin now.

$('input').on('ifChanged', function(event) {
             if($(".checkbox").is(":checked")) {
                $value = $(this).val();
             }

             else if($(".checkbox").is(":not(:checked)")) {
                $value= $(this).val();
             }
        });

In addition to the example given in the Advanced Bash Scripting Guide referenced by Jefromi, these examples show how pipes create subshells:

$ echo $$ $BASHPID | cat -
11656 31528
$ echo $$ $BASHPID
11656 11656
$ echo $$ | while read line; do echo $line $$ $BASHPID; done
11656 11656 31497
$ while read line; do echo $line $$ $BASHPID; done <<< $$
11656 11656 11656

If you know the items you are mapping through, you can accomplish this by doing one row at a time. I know it's a workaround, but it works.

For me I had 4 items per row, so I broke it up into two rows of 4 with each row height: 50%, get rid of flex-grow, have <RowOne /> and <RowTwo /> in a <div> with flex-column. This will do the trick

<div class='flexbox flex-column height-100-percent'>
   <RowOne class='flex height-50-percent' />
   <RowTwo class='flex height-50-percent' />
</div>

Since only one version of the run-time can be loaded into a process (although, as others have alluded, backwards loading - 4.0 loading 2.0 - is okay), you have a few options:

• Upgrade the .Net 2.0 project
• Wrap the .Net 2.0 project (if the source is not yours)
• Downgrade the .Net 4.0 project
• Load the .Net 4.0 project into it's own process (I believe this can work - but will take a bit of effort, IMO)

Simple and best code:

def max_occ(lst,x):
    count=0
    for i in lst:
        if (i==x):
            count=count+1
    return count

lst=[1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67]
x=max(lst,key=lst.count)
print(x,"occurs ",max_occ(lst,x),"times")

Output: 4 occurs 6 times

None of the above answers are actually correct, because they do not follow the semantics when there are duplicated values.

For a query such as (from this duplicate):

SELECT * FROM t1 FULL OUTER JOIN t2 ON t1.Name = t2.Name;

The correct equivalent is:

SELECT t1.*, t2.*
FROM (SELECT name FROM t1 UNION  -- This is intentionally UNION to remove duplicates
      SELECT name FROM t2
     ) n LEFT JOIN
     t1
     ON t1.name = n.name LEFT JOIN
     t2
     ON t2.name = n.name;

If you need for this to work with NULL values (which may also be necessary), then use the NULL-safe comparison operator, <=> rather than =.

Since hours are always positive, and always 2 digits, you can set a 1 in front of it and subtract 100:

echo $((1$hour+1-100))

which is equivalent to

echo $((1$hour-99))

Be sure to comment such gymnastics. :)

Another option is to use JS:

<img src='LibraryTransparent.png' onmouseover="this.src='LibraryHoverTrans.png';" onmouseout="this.src='LibraryTransparent.png';" />

I'm using the Hadoop Mincemeat module. I think this is a great example to take a note of:

import mincemeat

def mapfn(k,v):
    for w in v:
        yield 'sum',w
        #yield 'count',1


def reducefn(k,v): 
    r1=sum(v)
    r2=len(v)
    print r2
    m=r1/r2
    std=0
    for i in range(r2):
       std+=pow(abs(v[i]-m),2)  
    res=pow((std/r2),0.5)
    return r1,r2,res

Here the generator gets numbers out of a text file (as big as 15GB) and applies simple math on those numbers using Hadoop's map-reduce. If I had not used the yield function, but instead a list comprehension, it would have taken a much longer time calculating the sums and average (not to mention the space complexity).

Hadoop is a great example for using all the advantages of Generators.

Rather than the command "python", consider launching Python via the py launcher, as described in sg7's answer, which by runs your latest version of Python (or lets you select a specific version). The py launcher is enabled via a check box during installation (default: "on").

Nevertheless, you can still put the "python" command in your PATH, either at "first installation" or by "modifying" an existing installation.

First Installation:

Checking the "[x] Add Python x.y to PATH" box on the very first dialog. Here's how it looks in version 3.8:

This has the effect of adding the following to the PATH variable:

C:\Users\...\AppData\Local\Programs\Python\Python38-32\Scripts\
C:\Users\...\AppData\Local\Programs\Python\Python38-32\

Modifying an Existing Installation:

Re-run your installer (e.g. in Downloads, python-3.8.4.exe) and Select "Modify". Check all the optional features you want (likely no changes), then click [Next]. Check [x] "Add Python to environment variables", and [Install].

The safe way to do this is:

pkill -f amarok

I see that no good desciption for using numpy.nditer() is here. So, I am gonna go with one. According to NumPy v1.21 dev0 manual, The iterator object nditer, introduced in NumPy 1.6, provides many flexible ways to visit all the elements of one or more arrays in a systematic fashion.

I have to calculate mean_squared_error and I have already calculate y_predicted and I have y_actual from the boston dataset, available with sklearn.

def cal_mse(y_actual, y_predicted):
    """ this function will return mean squared error
       args:
           y_actual (ndarray): np array containing target variable
           y_predicted (ndarray): np array containing predictions from DecisionTreeRegressor
       returns:
           mse (integer)
    """
    sq_error = 0
    for i in np.nditer(np.arange(y_pred.shape[0])):
        sq_error += (y_actual[i] - y_predicted[i])**2
    mse = 1/y_actual.shape[0] * sq_error
    
    return mse

Hope this helps :). for further explaination visit

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")

Of course, you should modify this sample script based on your own application.

To color each cell based on its current integer value, the following should work, if you have a recent version of Excel. (Older versions don't handle rgb as well)

Sub Colourise()
'
' Colourise Macro
'
' Colours all selected cells, based on their current integer rgb value
' For e.g. (it's a bit backward from what you might expect)
' 255 = #ff0000 = red
' 256*255 = #00ff00 = green
' 256*256*255 #0000ff = blue
' 255 + 256*256*255 #ff00ff = magenta
' and so on...
'
' Keyboard Shortcut: Ctrl+Shift+C (or whatever you want to set it to)
'
  For Each cell In Selection
    If WorksheetFunction.IsNumber(cell) Then
      cell.Interior.Color = cell.Value
    End If
  Next cell
End Sub

If instead of a number you have a string then you can split the string into three numbers and combine them using rgb().

You can check iOS Version and simply set the tint color of Navigation bar.

if (SYSTEM_VERSION_LESS_THAN(@"7.0")) {
    self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
}else{

    self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
    self.navigationItem.leftBarButtonItem.tintColor = [UIColor whiteColor];
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}

Is your webservice configured correctly in IIS? The pool its using, the version of ASP.NET (2.0) is set? Can you browse the .asmx?

Talking about exceptions, try to put an try-catch block in the line that access your webservice. Put and catch(System.Web.Services.Protocolos.SoapException).

Also, you can set a Timeout for your webservice object.

Beware of using string interpolation for SQL queries, since it won't escape the input parameters correctly and will leave your application open to SQL injection vulnerabilities. The difference might seem trivial, but in reality it's huge.

Incorrect (with security issues)

c.execute("SELECT * FROM foo WHERE bar = %s AND baz = %s" % (param1, param2))

Correct (with escaping)

c.execute("SELECT * FROM foo WHERE bar = %s AND baz = %s", (param1, param2))

It adds to the confusion that the modifiers used to bind parameters in a SQL statement varies between different DB API implementations and that the mysql client library uses printf style syntax instead of the more commonly accepted '?' marker (used by eg. python-sqlite).

You don't say what shell you are using, but they generally don't support regular expressions that way, although there are common *nix CLI tools (grep, sed, etc) that do.

What shells like bash do support is globbing, which uses some similiar characters (eg, *) but is not the same thing.

Newer versions of bash do have a regular expression operator, =~:

for x in `ls`; do 
    if [[ $x =~ .+\..* ]]; then 
        echo $x; 
    fi; 
done

Try this, but you can adjust frame size with bounds and edit title.

package co.form.Try;

import javax.swing.JFrame;

public class Form {

    public static void main(String[] args) {
        JFrame obj =new JFrame();
        obj.setBounds(10,10,700,600); 
        obj.setTitle("Application Form");
        obj.setResizable(false);                
        obj.setVisible(true);       
        obj.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

}

You misspelled permission

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

In Main try changing the call to GetList to:

Task.Run(() => bs.GetList());

You cannot cast an int to a char* to get a string. Try this:

std::ostringstream sstream;
sstream << "select logged from login where id = " << ClientID;
std::string query = sstream.str();

In my case there was missing <RestorePackages>true</RestorePackages> in *.csproj file. It was not necessary to delete snippets of code I see in previous answers.

function abc() {
    var color = document.getElementById("test").style.color;
    color = (color=="red") ? "black" : "red" ;
    document.getElementById("test").style.color= color;
}

No, the methods don't need to be synchronized, and you don't need to define any methods; they are already in ConcurrentLinkedQueue, just use them. ConcurrentLinkedQueue does all the locking and other operations you need internally; your producer(s) adds data into the queue, and your consumers poll for it.

First, create your queue:

Queue<YourObject> queue = new ConcurrentLinkedQueue<YourObject>();

Now, wherever you are creating your producer/consumer objects, pass in the queue so they have somewhere to put their objects (you could use a setter for this, instead, but I prefer to do this kind of thing in a constructor):

YourProducer producer = new YourProducer(queue);

and:

YourConsumer consumer = new YourConsumer(queue);

and add stuff to it in your producer:

queue.offer(myObject);

and take stuff out in your consumer (if the queue is empty, poll() will return null, so check it):

YourObject myObject = queue.poll();

For more info see the Javadoc

EDIT:

If you need to block waiting for the queue to not be empty, you probably want to use a LinkedBlockingQueue, and use the take() method. However, LinkedBlockingQueue has a maximum capacity (defaults to Integer.MAX_VALUE, which is over two billion) and thus may or may not be appropriate depending on your circumstances.

If you only have one thread putting stuff into the queue, and another thread taking stuff out of the queue, ConcurrentLinkedQueue is probably overkill. It's more for when you may have hundreds or even thousands of threads accessing the queue at the same time. Your needs will probably be met by using:

Queue<YourObject> queue = Collections.synchronizedList(new LinkedList<YourObject>());

A plus of this is that it locks on the instance (queue), so you can synchronize on queue to ensure atomicity of composite operations (as explained by Jared). You CANNOT do this with a ConcurrentLinkedQueue, as all operations are done WITHOUT locking on the instance (using java.util.concurrent.atomic variables). You will NOT need to do this if you want to block while the queue is empty, because poll() will simply return null while the queue is empty, and poll() is atomic. Check to see if poll() returns null. If it does, wait(), then try again. No need to lock.

Finally:

Honestly, I'd just use a LinkedBlockingQueue. It is still overkill for your application, but odds are it will work fine. If it isn't performant enough (PROFILE!), you can always try something else, and it means you don't have to deal with ANY synchronized stuff:

BlockingQueue<YourObject> queue = new LinkedBlockingQueue<YourObject>();

queue.put(myObject); // Blocks until queue isn't full.

YourObject myObject = queue.take(); // Blocks until queue isn't empty.

Everything else is the same. Put probably won't block, because you aren't likely to put two billion objects into the queue.

A UIImage has a property imageOrientation, which instructs the UIImageView and other UIImage consumers to rotate the raw image data. There's a good chance that this flag is being saved to the exif data in the uploaded jpeg image, but the program you use to view it is not honoring that flag.

To rotate the UIImage to display properly when uploaded, you can use a category like this:

UIImage+fixOrientation.h

@interface UIImage (fixOrientation)

- (UIImage *)fixOrientation;

@end

UIImage+fixOrientation.m

@implementation UIImage (fixOrientation)

- (UIImage *)fixOrientation {

    // No-op if the orientation is already correct
    if (self.imageOrientation == UIImageOrientationUp) return self;

    // We need to calculate the proper transformation to make the image upright.
    // We do it in 2 steps: Rotate if Left/Right/Down, and then flip if Mirrored.
    CGAffineTransform transform = CGAffineTransformIdentity;

    switch (self.imageOrientation) {
        case UIImageOrientationDown:
        case UIImageOrientationDownMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.width, self.size.height);
            transform = CGAffineTransformRotate(transform, M_PI);
            break;

        case UIImageOrientationLeft:
        case UIImageOrientationLeftMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.width, 0);
            transform = CGAffineTransformRotate(transform, M_PI_2);
            break;

        case UIImageOrientationRight:
        case UIImageOrientationRightMirrored:
            transform = CGAffineTransformTranslate(transform, 0, self.size.height);
            transform = CGAffineTransformRotate(transform, -M_PI_2);
            break;
        case UIImageOrientationUp:
        case UIImageOrientationUpMirrored:
            break;
    }

    switch (self.imageOrientation) {
        case UIImageOrientationUpMirrored:
        case UIImageOrientationDownMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.width, 0);
            transform = CGAffineTransformScale(transform, -1, 1);
            break;

        case UIImageOrientationLeftMirrored:
        case UIImageOrientationRightMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.height, 0);
            transform = CGAffineTransformScale(transform, -1, 1);
            break;
        case UIImageOrientationUp:
        case UIImageOrientationDown:
        case UIImageOrientationLeft:
        case UIImageOrientationRight:
            break;
    }

    // Now we draw the underlying CGImage into a new context, applying the transform
    // calculated above.
    CGContextRef ctx = CGBitmapContextCreate(NULL, self.size.width, self.size.height,
                                             CGImageGetBitsPerComponent(self.CGImage), 0,
                                             CGImageGetColorSpace(self.CGImage),
                                             CGImageGetBitmapInfo(self.CGImage));
    CGContextConcatCTM(ctx, transform);
    switch (self.imageOrientation) {
        case UIImageOrientationLeft:
        case UIImageOrientationLeftMirrored:
        case UIImageOrientationRight:
        case UIImageOrientationRightMirrored:
            // Grr...
            CGContextDrawImage(ctx, CGRectMake(0,0,self.size.height,self.size.width), self.CGImage);
            break;

        default:
            CGContextDrawImage(ctx, CGRectMake(0,0,self.size.width,self.size.height), self.CGImage);
            break;
    }

    // And now we just create a new UIImage from the drawing context
    CGImageRef cgimg = CGBitmapContextCreateImage(ctx);
    UIImage *img = [UIImage imageWithCGImage:cgimg];
    CGContextRelease(ctx);
    CGImageRelease(cgimg);
    return img;
}

@end

TRUE and FALSE are keywords, and should not be quoted as strings:

INSERT INTO first VALUES (NULL, 'G22', TRUE);
INSERT INTO first VALUES (NULL, 'G23', FALSE);

By quoting them as strings, MySQL will then cast them to their integer equivalent (since booleans are really just a one-byte INT in MySQL), which translates into zero for any non-numeric string. Thus, you get 0 for both values in your table.

Non-numeric strings cast to zero:

mysql> SELECT CAST('TRUE' AS SIGNED), CAST('FALSE' AS SIGNED), CAST('12345' AS SIGNED);
+------------------------+-------------------------+-------------------------+
| CAST('TRUE' AS SIGNED) | CAST('FALSE' AS SIGNED) | CAST('12345' AS SIGNED) |
+------------------------+-------------------------+-------------------------+
|                      0 |                       0 |                   12345 |
+------------------------+-------------------------+-------------------------+

But the keywords return their corresponding INT representation:

mysql> SELECT TRUE, FALSE;
+------+-------+
| TRUE | FALSE |
+------+-------+
|    1 |     0 |
+------+-------+

Note also, that I have replaced your double-quotes with single quotes as are more standard SQL string enclosures. Finally, I have replaced your empty strings for id with NULL. The empty string may issue a warning.

In angular only one page is requested from server, that is index.html. And index.html and assets folder are on same directory. while putting image in any component give src value like assets\image.png. This will work fine because browser will make request to server for that image and webpack will be able serve that image.

This is the way:

/usr/bin/php -q /home/username/public_html/yourfilename.php >/dev/null

It might be possible to delete the Zone Record entirely, then recreate it exactly as you want it. Perhaps this will force a full propagation. If I'm wrong, somebody tell me and I'll delete this suggestion. Also, I don't know how to save a Zone Record and recreate it using WHM or any other tool.

I do know that when I deleted a hosting account today and recreated it, the original Zone Record seemed to be propagated instantly to a DNS resolver up the line from my computer. That is good evidence it works.

This is the natural javascript option

var myArray = ['1','2',3,4]_x000D_
_x000D_
myArray.forEach(function(value){_x000D_
  console.log(value);_x000D_
});

However it won't work if you're using await inside the forEach loop because forEach is not asynchronous. you'll be forced to use the second answer or some other equivalent:

let myArray = ["a","b","c","d"];_x000D_
for (let item of myArray) {_x000D_
  console.log(item);_x000D_
}

Or you could create an asyncForEach explained here:

https://codeburst.io/javascript-async-await-with-foreach-b6ba62bbf404

fmt.Println("%+v", structure variable)

A better way to do this would be to create a global constant for the string "%+v" in a package called "commons"(maybe) and use it everywhere in your code

//In commons package
const STRUCTURE_DATA_FMT = "%+v"

//In your code everywhere
fmt.Println(commons.STRUCTURE_DATA_FMT, structure variable)

Add: now you can use lambda to simplify your syntax. Requirement: Java 8+

public class A {
    public static void main(String[] arg)
    {
        Thread th = new Thread(() -> {System.out.println("blah");});
        th.start();
    }
}

Both getsize() and stat() will throw an exception if the file does not exist. This function will return True/False without throwing (simpler but less robust):

import os
def is_non_zero_file(fpath):  
    return os.path.isfile(fpath) and os.path.getsize(fpath) > 0

Listed are the steps that could rectify the error:

1. Press Windows+R
2. Type services.msc and strike Enter
3. Find all services
4. Starting with ora start these services and wait!!
5. When your server specific service is initialized (in my case it was orcl)
6. Now run mysql or whatever you are using and start coding.P

May be it's obvious for expert users of MYSQL but I wasted some time while trying to figure out default value would not export functions. So I thought to mention here that --routines param needs to be set to true to make it work.

mysqldump --routines=true -u <user> my_database > my_database.sql

You can consider using memory-mapped files, via FileChannels .

Generally a lot faster for large files. There are performance trade-offs that could make it slower, so YMMV.

It is not listed as a function in dplyr (yet): http://cran.rstudio.org/web/packages/dplyr/dplyr.pdf

For Access (or any SQL language)

1. Create one table that has 2 fields, we'll call this table tempRunDates:
   --Fields fromDate and toDate
   --Then insert only 1 record, that has the start date and the end date.

2. Create another table: Time_Day_Ref
   --Import a list of dates (make list in excel is easy) into this table.
   --The field name in my case is Greg_Dt, for Gregorian Date
   --I made my list from jan 1 2009 through jan 1 2020.

3. Run the query:

   SELECT Time_Day_Ref.GREG_DT
   FROM tempRunDates, Time_Day_Ref
   WHERE Time_Day_Ref.greg_dt>=tempRunDates.fromDate And greg_dt<=tempRunDates.toDate;
   

Easy!

With Java 8 it is so simple so it doesn't even need separate method anymore:

List<Integer> range = IntStream.rangeClosed(start, end)
    .boxed().collect(Collectors.toList());

Try this:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

zzz is the timezone offset.

A subscript and referring to a stored value...

a <- 10
plot(c(0,1), c(0,1), type = 'n', ann = FALSE, xaxt = 'n', yaxt = 'n')
text(0.2, 0.6, cex = 1.5, bquote(paste('S'['f']*' = ', .(a))))

This works in the note-taking Joplin:

<span style="color:red">text in red</span>

Seems to work

$(".selector").change(function() {

    var $value = $(this).val();

    var $title = $(this).children('option[value='+$value+']').html();

    $('#bacon').val($title);

});

Just check with your firebug. And don't put css on hidden input.

Yes, it's possible, from @Fábio Zangirolami answer

audio::-webkit-media-controls-panel, video::-webkit-media-controls-panel {
                background-color: red;
}

Android Support Library now handles WRAP_CONTENT property as well. Just import this in your gradle.

compile 'com.android.support:recyclerview-v7:23.2.0'

And done!

You don't need git to accomplish this. Creative use of a bash function will do the trick just fine. If you don't care about messages, just set a default one and forget it.

function gitcom() {
  git commit -m "my default commit message"
}

If you were feeling really adventurous you could add, commit and push with one command

function gitzap() {
  git add . && git commit -m "whatevs" && git push $1 $2
}

Which you would then run as

gitzap origin master

You could even get deeper and use parse_git_branch to save yourself some keystrokes there, or set a common default of "origin" and "master".

If both columns can contain NULL, but you still want to merge them to a single string, the easiest solution is to use CONCAT_WS():

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT_WS('', ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

This way you won't have to check for NULL-ness of each column separately.

Alternatively, if both columns are actually defined as NOT NULL, CONCAT() will be quite enough:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

As for COALESCE, it's a bit different beast: given the list of arguments, it returns the first that's not NULL.

One graph can replace many words:

Enjoy! :-)

# I have updated the correct image...

Lodash has a chunk method built-in now which I personally use: https://lodash.com/docs#chunk

Based on this, controller code might look like the following:

$scope.groupedUsers = _.chunk( $scope.users, 3 )

View code:

<div class="row" ng-repeat="rows in groupedUsers">
  <div class="span4" ng-repeat="item in rows">{{item}}</div>
</div>

I have just compile it and it compiles fine without the implicit import, probably you're seeing a stale cache or something of your IDE.

Have you tried compiling from the command line?

I have the exact same version:

Probably you're thinking the warning is an error.

UPDATE

It looks like you have a Arrays.class file in the directory where you're trying to compile ( probably created before ). That's why the explicit import solves the problem. Try copying your source code to a clean new directory and try again. You'll see there is no error this time. Or, clean up your working directory and remove the Arrays.class

given the sorted content of your array, there is an even faster method: searchsorted.

import time
N = 10000
aa = np.arange(-N,N)
%timeit np.searchsorted(aa, N/2)+1
%timeit np.argmax(aa>N/2)
%timeit np.where(aa>N/2)[0][0]
%timeit np.nonzero(aa>N/2)[0][0]

# Output

Double click your button and use the following code :-

protected void button_click(object sender,EventArgs e)
{
 int parsedValue;
 if(int.TryParse(!txt.Text,out parsedValue))
 {
 Label.Text = "Please specify a number only !!"; //Will put a text in a label so make     
    //sure                
  //you have a label
 }
 else
  {
    // do what you want to  
  }

Is this any help?

#include <stdio.h>

#define MAX 10

int main()
{
    char grid[MAX][MAX];
    int i,j,row,col;

    printf("Please enter your grid size: ");
    scanf("%d %d", &row, &col);


    for (i = 0; i < row; i++) {
        for (j = 0; j < col; j++) {
            grid[i][j] = '.';
            printf("%c ", grid[i][j]);
        }
        printf("\n");
    }

    return 0;
}

The dict.pop(key[, default]) method allows you to remove items when you know the key. It returns the value at the key if it removes the item otherwise it returns what is passed as default. See the docs.'

Example:

>>> dic = {'a':1, 'b':2}
>>> dic
{'a': 1, 'b': 2}
>>> dic.pop('c', 0)
0
>>> dic.pop('a', 0)
1
>>> dic
{'b': 2}

- Each time you append or do any modification with it, it creates a new String object.

- So use append() method of StringBuilder(If thread safety is not important), else use StringBuffer(If thread safety is important.), that will be efficient way to do it.

For anyone reading this who is using EclipseLink for JPA 2.0, here are the two annotations I had to use to get JPA to persist data, where "MySequenceGenerator" is whatever name you want to give the generator, "myschema" is the name of the schema in your database that contains the sequence object, and "mysequence" is the name of the sequence object in the database.

@GeneratedValue(strategy= GenerationType.SEQUENCE, generator="MySequenceGenerator")
@SequenceGenerator(allocationSize=1, schema="myschema",  name="MySequenceGenerator", sequenceName = "mysequence")

For those using EclipseLink (and possibly other JPA providers), it is CRITICAL that you set the allocationSize attribute to match the INCREMENT value defined for your sequence in the database. If you don't, you'll get a generic persistence failure, and waste a good deal of time trying to track it down, like I did. Here is the reference page that helped me overcome this challenge:

http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey#Using_Sequence_Objects

Also, to give context, here is what we're using:

Java 7 Glassfish 3.1 PostgreSQL 9.1 PrimeFaces 3.2/JSF 2.1

Also, for laziness' sake, I built this in Netbeans with the wizards for generating Entities from DB, Controllers from Entities, and JSF from Entities, and the wizards (obviously) do not know how to deal with sequence-based ID columns, so you'll have to manually add these annotations.

Logically OLAP functions are calculated after GROUP BY/HAVING, so you can only access columns in GROUP BY or columns with an aggregate function. Following looks strange, but is Standard SQL:

SELECT employee_number,
       MAX(MAX(course_completion_date)) 
           OVER (PARTITION BY course_code) AS max_course_date,
       MAX(course_completion_date) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

And as Teradata allows re-using an alias this also works:

SELECT employee_number,
       MAX(max_date) 
           OVER (PARTITION BY course_code) AS max_course_date,
       MAX(course_completion_date) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

Here is a way to remove a specific commit id knowing only the commit id you would like to remove.

git rebase --onto commit-id^ commit-id

Note that this actually removes the change that was introduced by the commit.

You can simply show your actual image directory(less secure). By just 2 line of code.

 $dir = base_url()."photos/";

echo"<a href=".$dir.">Photo Directory</a>";

I'm assuming that you're trying to deal with Ajax navigation and not trying to prevent your users from using the back button, which violates just about every tenet of UI development ever.

Here's some possible solutions: JQuery History Salajax A Better Ajax Back Button

JSONArray may be what you want.

String message;
JSONObject json = new JSONObject();
json.put("name", "student");

JSONArray array = new JSONArray();
JSONObject item = new JSONObject();
item.put("information", "test");
item.put("id", 3);
item.put("name", "course1");
array.put(item);

json.put("course", array);

message = json.toString();

// message
// {"course":[{"id":3,"information":"test","name":"course1"}],"name":"student"}

My case of working code is:

var request = new XMLHttpRequest();
request.open("GET", "<path_to_file>", false);
request.overrideMimeType("application/json");
request.send(null);
var jsonData = JSON.parse(request.responseText);
console.log(jsonData);

You would use off() to remove an event like so:

$("#saveBtn").off("click");

but this will remove all click events bound to this element. If the function with SaveQuestion is the only event bound then the above will do it. If not do the following:

$("#saveBtn").off("click").click(function() { saveQuestion(id); });

I've just succeeded!

1. Copy the mylib-0.1.aar file into the libs/ folder

2. Add these lines to the bottom of build.gradle (should be app, not project):

   repositories {
      flatDir {
          dirs 'libs'
      }
   }
   dependencies {
       compile 'com.example.lib:mylib:0.1@aar'
   }
   

3. So far so good. Here comes the most important point:

Gradle needs to access the network for dependencies unless offline mode is enabled.

Make sure that you have enabled Offline work via the checkbox in Project Structures/Gradle

-- OR --

Configure the proxy settings in order to access the network.

To configure the proxy settings you have to modify the project's gradle.properties file, configuring http and https separately as below:

systemProp.http.proxyHost=proxy.example.com
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=user
systemProp.http.proxyPassword=pass
systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=example <for NT auth>

systemProp.https.proxyHost=proxy.example.com
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=user
systemProp.https.proxyPassword=pass
systemProp.https.nonProxyHosts=localhost
systemProp.https.auth.ntlm.domain=example <for NT auth>

Hope this works.

You can use case in update and SWAP as many as you want

update Table SET column=(case when is_row_1 then value_2 else value_1 end) where rule_to_match_swap_columns

The compiler wants to know the function before it can use it

just declare the function before you call it

#include <stdio.h>

int Fibonacci(int number); //now the compiler knows, what the signature looks like. this is all it needs for now

int main(int argc, const char * argv[])
{
    int input;
    printf("Please give me a number : ");
    scanf("%d", &input);
    getchar();
    printf("The fibonacci number of %d is : %d", input, Fibonacci(input)); //!!!

}/* main */

int Fibonacci(int number)
{
//…

These solutions will work:

<body onload="script();">

or

document.onload = function ...

or even

window.onload = function ...

Note that the last option is a better way to go since it is unobstrusive and is considered more standard.

See this related thread. Basically, os.environ is found on import, and os.getenv is a wrapper to os.environ.get, at least in CPython.

EDIT: To respond to a comment, in CPython, os.getenv is basically a shortcut to os.environ.get ; since os.environ is loaded at import of os, and only then, the same holds for os.getenv.

foreach (GridViewRow gvr in gvMyGridView.Rows)
{
    string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}

You can use this code while doing an iteration with foreach or for any GridView event like OnRowDataBound.

Here you can input multiple values for DataKeyNames by separating with comma ,. For example, DataKeyNames="ProductID,ItemID,OrderID".

You can now access each of DataKeys by providing its index like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();

You can also use Key Name instead of its index to get the values from DataKeyNames collection like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();

$(document).ready(function(){
$("#HoursEntry").change(function(){
var HoursEntry = $(#HoursEntry option:selected).val();
if(HoursEntry == "")
{
$("#HoursEntry").html("Please select");
return false;
}
});
});

int main(){
    int i=0;
    int a=0;
    for(i;i<5;i++,a++){
        printf("%d %d\n",a,i);
    } 
}

F1 → open Keyboard Shortcuts → search for 'Indent Line', and change keybinding to Tab.

Right click > "Change when expression" to editorHasSelection && editorTextFocus && !editorReadonly

It will allow you to indent line when something in that line is selected (multiple lines still work).

This sometimes happens with Excel when you've recently used "Text to Columns."

Try exiting out of excel, reopening, and pasting again. That usually works for me, but I've heard you sometimes have to restart your computer altogether.

function converToLocalTime(serverDate) {

    var dt = new Date(Date.parse(serverDate));
    var localDate = dt;
    
    var gmt = localDate;
        var min = gmt.getTime() / 1000 / 60; // convert gmt date to minutes
        var localNow = new Date().getTimezoneOffset(); // get the timezone
        // offset in minutes
        var localTime = min - localNow; // get the local time

    var dateStr = new Date(localTime * 1000 * 60);
    // dateStr = dateStr.toISOString("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"); // this will return as just the server date format i.e., yyyy-MM-dd'T'HH:mm:ss.SSS'Z'
    dateStr = dateStr.toString("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
    return dateStr;
}

The Ruby File class will give you the ins and outs of ::new and ::open but its parent, the IO class, gets into the depth of #read and #write.

Here is the syntax to create a trigger:

CREATE TRIGGER trigger_name
ON { table | view }
[ WITH ENCRYPTION ]
{
    { { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] }
        [ WITH APPEND ]
        [ NOT FOR REPLICATION ]
        AS
        [ { IF UPDATE ( column )
            [ { AND | OR } UPDATE ( column ) ]
                [ ...n ]
        | IF ( COLUMNS_UPDATED ( ) { bitwise_operator } updated_bitmask )
                { comparison_operator } column_bitmask [ ...n ]
        } ]
        sql_statement [ ...n ]
    }
} 

If you want to use On Update you only can do it with the IF UPDATE ( column ) section. That's not possible to do what you are asking.

Please see the following Python shell scripting execution in sequence, it will give the solution from creation of class to extracting the field names of instances.

So the answers I read here are mostly lengthy. The shortest answer by Alex works good, but not so clean.

Best part is that unlike others', it works fast.

I came up with my own one-liner:

FOR /F "usebackq tokens=3,4,5" %i IN (`REG query "hklm\software\microsoft\windows NT\CurrentVersion" /v ProductName`) DO echo %i %j %k

Above is for command prompt. To make it work in batch file, replace all % with %% to make it look like:

FOR /F "usebackq tokens=3,4,5" %%i IN (`REG query "hklm\software\microsoft\windows NT\CurrentVersion" /v ProductName`) DO echo %%i %%j %%k

In my computer, it simply produces Windows 10 Pro

$(window).scroll(function () {

        var ControlDivTop = $('#cs_controlDivFix');

        $(window).scroll(function () {
            if ($(this).scrollTop() > 50) {
               ControlDivTop.stop().animate({ 'top': ($(this).scrollTop() - 62) + "px" }, 600);
            } else {
              ControlDivTop.stop().animate({ 'top': ($(this).scrollTop()) + "px" },600);
            }
        });
    });

Just got it. As regan pointed out, I had to add the user to the sudoers group. But the main reason was I'd forgotten to update the repositories cache, so apt-get couldn't find the sudo package. It's working now. Here's the completed code:

FROM ubuntu:12.04

RUN apt-get update && \
      apt-get -y install sudo

RUN useradd -m docker && echo "docker:docker" | chpasswd && adduser docker sudo

USER docker
CMD /bin/bash

This is not an answer to the original question "What are the differences between .gitignore and .gitkeep?" but posting here to help people to keep track of empty dir in a simple fashion. To track empty directory and knowling that .gitkeep is not official part of git,

just add a empty (with no content) .gitignore file in it.

So for e.g. if you have /project/content/posts and sometimes posts directory might be empty then create empty file /project/content/posts/.gitignore with no content to track that directory and its future files in git.

You can do like this :

count = 0
cnxn = pyodbc.connect("Driver={SQL Server Native Client 11.0};"
                      "Server=serverName;"
                      "Trusted_Connection=yes;")
cursor = cnxn.cursor()
cursor.execute(SQL query)
for row in cursor:
    count = 1
    if true condition:
        print("True")
    else:
        print("False")
if count == 0:
    print("No Result")

Thanks :)

jQlite (angular's "jQuery" port) doesn't support lookup by classes.

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

We use the first item in the element array, which is the HTML element. element.eq(0) would yield the same.

FIDDLE

Use and empty() whit negation (for test if not empty)

if(!empty($_GET['id'])) {
    // if get id is not empty
}

Something like this would resemble a button:

a.LinkButton {
  border-style: solid;
  border-width : 1px 1px 1px 1px;
  text-decoration : none;
  padding : 4px;
  border-color : #000000
}

See http://jsfiddle.net/r7v5c/1/ for an example.

I prefer to use sub query list:

rm -r `ls | grep -v "textfile.txt\|backup.tar.gz\|script.php\|database.sql\|info.txt"`

-v, --invert-match select non-matching lines

\| Separator

I got this error message when sending data from a html form (Post method). All I had to do was change the encoding in the form from "text/plain" to "application/x-www-form-urlencoded" or "multipart/form-data". The error message was very misleading.

Without itertools in Python 3 you could do something like this:

def combinations(arr, carry):
    for i in range(len(arr)):
        yield carry + arr[i]
        yield from combinations(arr[i + 1:], carry + arr[i])

where initially carry = "".

I think that the best approach is to just create a new instance of a class and than assign the object. Here's what I would do:

public function ($someVO) {

     $someCastVO = new SomeVO();
     $someCastVO = $someVO;
     $someCastVO->SomePropertyInVO = "123";

}

Doing this will give you code hinting in most IDEs and help ensure you are using the correct properties.

You can remove the restriction by seting it to zero by adding this line at the top of your script:

<?php ini_set('max_execution_time', '0'); ?>

java.io.File class contains four static separator variables. For better understanding, Let's understand with the help of some code

1. separator: Platform dependent default name-separator character as String. For windows, it’s ‘\’ and for unix it’s ‘/’
2. separatorChar: Same as separator but it’s char
3. pathSeparator: Platform dependent variable for path-separator. For example PATH or CLASSPATH variable list of paths separated by ‘:’ in Unix systems and ‘;’ in Windows system
4. pathSeparatorChar: Same as pathSeparator but it’s char

Note that all of these are final variables and system dependent.

Here is the java program to print these separator variables. FileSeparator.java

import java.io.File;

public class FileSeparator {

    public static void main(String[] args) {
        System.out.println("File.separator = "+File.separator);
        System.out.println("File.separatorChar = "+File.separatorChar);
        System.out.println("File.pathSeparator = "+File.pathSeparator);
        System.out.println("File.pathSeparatorChar = "+File.pathSeparatorChar);
    }

}

Output of above program on Unix system:

File.separator = /
File.separatorChar = /
File.pathSeparator = :
File.pathSeparatorChar = :

Output of the program on Windows system:

File.separator = \
File.separatorChar = \
File.pathSeparator = ;
File.pathSeparatorChar = ;

To make our program platform independent, we should always use these separators to create file path or read any system variables like PATH, CLASSPATH.

Here is the code snippet showing how to use separators correctly.

//no platform independence, good for Unix systems
File fileUnsafe = new File("tmp/abc.txt");
//platform independent and safe to use across Unix and Windows
File fileSafe = new File("tmp"+File.separator+"abc.txt");

I usually use a plain old VARCHAR filtering for an IPAddress works fine.

If you want to filter on ranges of IP address I'd break it into four integers.

On Windows7 all the databases are referred by a number in the file named pg_database under C:\Program Files (x86)\PostgreSQL\8.2\data\global. Then you should search for the folder name by that number under C:\Program Files (x86)\PostgreSQL\8.2\data\base. That is the content of the database.

I know it really late for another answer but I just wanted to share what helped me at the end. It will also load resources/files from the absolute path of the file system (not only the classpath's).

public class ResourceLoader {

    public static URL getResource(String resource) {
        final List<ClassLoader> classLoaders = new ArrayList<ClassLoader>();
        classLoaders.add(Thread.currentThread().getContextClassLoader());
        classLoaders.add(ResourceLoader.class.getClassLoader());

        for (ClassLoader classLoader : classLoaders) {
            final URL url = getResourceWith(classLoader, resource);
            if (url != null) {
                return url;
            }
        }

        final URL systemResource = ClassLoader.getSystemResource(resource);
        if (systemResource != null) {
            return systemResource;
        } else {
            try {
                return new File(resource).toURI().toURL();
            } catch (MalformedURLException e) {
                return null;
            }
        }
    }

    private static URL getResourceWith(ClassLoader classLoader, String resource) {
        if (classLoader != null) {
            return classLoader.getResource(resource);
        }
        return null;
    }

}

myvariable=$(mysql database -u $user -p$password | SELECT A, B, C FROM table_a)

without the blank space after -p. Its trivial, but without don't work.

If the starting cell of the range and of the key is static, the solution can be very simple:

Range("A3").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Sort key1:=Range("B3", Range("B3").End(xlDown)), _
order1:=xlAscending, Header:=xlNo

you can test if have exactly some values, by example:

for(MyBoolean b : MyBoolean.values()) {
    switch(b) {
    case TRUE:
        break;
    case FALSE:
        break;
    default:
        throw new IllegalArgumentException(b.toString());
}

for(String s : new String[]{"TRUE", "FALSE" }) {
    MyBoolean.valueOf(s);
}

If someone removes or adds a value, some of test fails.

I want to extend MattMitchell's answer by saying you can create an extension method for this functionality:

public static IsEmptyOrWhitespace(this string value) {
    return String.IsEmptyOrWhitespace(value);
}

This makes it possible to call:

string strValue;
if (strValue.IsEmptyOrWhitespace())
     // do stuff

To me this is a lot cleaner than calling the static String function, while still being NullReference safe!

Too bad that Sharon's solution cannot be used anymore. I've added Josh O'Brien's solution with asieira's modification to my .Rprofile file:

read.text = function(pathname)
{
    return (paste(readLines(pathname), collapse="\n"))
}

and use it like this: txt = read.text('path/to/my/file.txt'). I couldn't replicate bumpkin's (28 oct. 14) finding, and writeLines(txt) showed the contents of file.txt. Also, after write(txt, '/tmp/out') the command diff /tmp/out path/to/my/file.txt reported no differences.

Future.delayed(Duration(seconds: 3) , your_function)

well, i had a similar problem, so when i entered, lets say: localhost/test.php I would got Object not found warning! I solved my problem when i realized that windows changed my test.php into this test.php.txt. I changed my extension and voila! problem solved I could finaly acceses localhost/test.php.

The parameters to main represent the command line parameters provided to the program when it was started. The argc parameter represents the number of command line arguments, and char *argv[] is an array of strings (character pointers) representing the individual arguments provided on the command line.

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

Use strlen to get the length of a null-terminated string.

sizeof returns the length of the array not the string. If it's a pointer (char *s), not an array (char s[]), it won't work, since it will return the size of the pointer (usually 4 bytes on 32-bit systems). I believe an array will be passed or returned as a pointer, so you'd lose the ability to use sizeof to check the size of the array.

So, only if the string spans the entire array (e.g. char s[] = "stuff"), would using sizeof for a statically defined array return what you want (and be faster as it wouldn't need to loop through to find the null-terminator) (if the last character is a null-terminator, you will need to subtract 1). If it doesn't span the entire array, it won't return what you want.

An alternative to all this is actually storing the size of the string.

If your user account has spaces in it and you have tried all the above but none worked,

I recommended you create a new windows user account and give it an administrative privilege, not standard.

Log out of your old account and log into this new account and try installing again. It worked well.

This code snippet shows how to insert into table when identity Primary Key column is ON.

SET IDENTITY_INSERT [dbo].[Roles] ON
GO
insert into Roles (Id,Name) values(1,'Admin')
GO
insert into Roles (Id,Name) values(2,'User')
GO
SET IDENTITY_INSERT [dbo].[Roles] OFF
GO

Included below is a simple working JS/HTML implementation which updates the remaining characters properly when the input has been deleted.

Bootstrap and JQuery are required for the layout and functionality to match. (Tested on JQuery 2.1.1 as per the included code snippet).

Make sure you include the JS code such that it is loaded after the HTML. Message me if you have any questions.

Pretty basic but works:

function dynamicHeight() {
    var height = jQuery('').height();
    jQuery('.edito-wrapper').css('height', editoHeight);
}
editoHeightSize();

jQuery(window).resize(function () {
    editoHeightSize();
});

The view's window property is non-nil if a view is currently visible, so check the main view in the view controller:

Invoking the view method causes the view to load (if it is not loaded) which is unnecessary and may be undesirable. It would be better to check first to see if it is already loaded. I've added the call to isViewLoaded to avoid this problem.

if (viewController.isViewLoaded && viewController.view.window) {
    // viewController is visible
}

Since iOS9 it has became easier:

if viewController.viewIfLoaded?.window != nil {
    // viewController is visible
}

Or if you have a UINavigationController managing the view controllers, you could check its visibleViewController property instead.

Just like any other click event, you can use jQuery to register an element, set an id to the element and listen to events like so:

$('#myButton').on('click', function(event) {
  event.preventDefault(); // To prevent following the link (optional)
  ...
});

You can also use inline javascript in the onclick attribute:

<a ... onclick="myFunc();">..</a>

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

See a live demo.

For the sake of keeping things simple, I haven't written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.

$('div#someDiv').css('height', '');

You should be able to set these via the attr() or prop() functions in jQuery as shown below:

jQuery (< 1.7):

// This will disable just the div
$("#dcacl").attr('disabled','disabled');

or

// This will disable everything contained in the div
$("#dcacl").children().attr("disabled","disabled");

jQuery (>= 1.7):

// This will disable just the div
$("#dcacl").prop('disabled',true);

or

// This will disable everything contained in the div
$("#dcacl").children().prop('disabled',true);

or

//  disable ALL descendants of the DIV
$("#dcacl *").prop('disabled',true);

Javascript:

// This will disable just the div
document.getElementById("dcalc").disabled = true;

or

// This will disable all the children of the div
var nodes = document.getElementById("dcalc").getElementsByTagName('*');
for(var i = 0; i < nodes.length; i++){
     nodes[i].disabled = true;
}

No need to do execute batch command. With the current version, just run BLUESTACKS before ANDROID STUDIO

The Google Plugin for Eclipse depends on other specific Eclipse components, such as WST. Your installation of Eclipse may not yet include all of them, but they can be easily installed by following these instructions. Eclipse 3.7 (Indigo)

 Select Help > Install New Software...

Click the link for Available Software Sites.
Ensure there is an update site named Indigo. 

If this is not present, click Add... and 
enter http://download.eclipse.org/releases/indigo for the Location.

Now go through the installation steps; Eclipse should download and install 
the plugin's dependencies.

The syntax for using an alias in an update statement on SQL Server is as follows:

UPDATE Q
SET Q.TITLE = 'TEST'
FROM HOLD_TABLE Q
WHERE Q.ID = 101;

The alias should not be necessary here though.

The correct format for url can be one of the following formats:

jdbc:oracle:thin:@<hostName>:<portNumber>:<sid>;  (if you have sid)
jdbc:oracle:thin:@//<hostName>:<portNumber>/serviceName; (if you have oracle service name)

And don't put any space there. Try to use 1521 as port number. sid (database name) must be the same as the one which is in environment variables (if you are using windows).

In your build.gradle(Module:app), add android-gif-drawable as a dependency by adding the following code:

allprojects {
    repositories {
       mavenCentral()
    }
}

dependencies {
    compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
}

dependencies {
    implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
}

Then sync your project. When synchronization ends, go to your layout file and add the following code:

<pl.droidsonroids.gif.GifImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/gif_file"
/>

And that's it, you can manage it with a simple ImageView.

I suppose you have figured it out by now. The answer is hidden in your first mail itself.

The make command by default looks for makefile, Makefile, and GNUMakefile as the input file and you are having Makefile.txt in your folder. Just remove the file extension (.txt) and it should work.

from app import SQLAlchemyDB as db

Chance.query.filter(Chance.repo_id==repo_id, 
                    Chance.status=="1", 
                    db.func.date(Chance.apply_time)<=end, 
                    db.func.date(Chance.apply_time)>=start).count()

it is equal to:

select
   count(id)
from
   Chance
where
   repo_id=:repo_id 
   and status='1'
   and date(apple_time) <= end
   and date(apple_time) >= start

wish can help you.

Install Babun instead -> https://babun.github.io/index.html It contains Cygwin ;)

Piggybacking on what the other answers say, since you don't know how to do them at all, here's an example of how you might do it in JavaScript:

var charactersOnly = "This contains only characters";
var nonCharacters = "This has _@#*($()*@#$(*@%^_(#@!$ non-characters";

if (charactersOnly.search(/[^a-zA-Z]+/) === -1) {
  alert("Only characters");
}

if (nonCharacters.search(/[^a-zA-Z]+/)) {
  alert("There are non characters.");
}

The / starting and ending the regular expression signify that it's a regular expression. The search function takes both strings and regexes, so the / are necessary to specify a regex.

From the MDN Docs, the function returns -1 if there is no match.

Also note: that this works for only a-z, A-Z. If there are spaces, it will fail.

If updating cURL doesn't fix it, updating NSS should do the trick.

I have only tested with EditText but you can use the method

public void setBackgroundResource (int resid)

to apply a style defined in an XML file.

Sine this method belongs to View I believe it will work with any UI element.

regards.

You could use a Bat to Exe converter from here:

http://www.f2ko.de/en/b2e.php

This will convert your batch file to an executable, then you can set the icon for the converted file.

I had to:

Delete node_modules
Uninstall/reinstall node
npm install [email protected]

worked fine after forcing it to the right sass version, according to the version said to be working with the right node.

NodeJS  Minimum node-sass version   Node Module
Node 12 4.12+   72
Node 11 4.10+   67
Node 10 4.9+    64
Node 8  4.5.3+  57

There was lots of other errors that seemed to be caused by the wrong sass version defined.

For those who will need to remove product key from Visual Studio 2015:

1. remove registry key HKCR\Licenses\4D8CFBCB-2F6A-4AD2-BABF-10E28F6F2C8F
2. repair Visual Studio installation

That's it, now you can change the product key if necessary.

Just to expand on juanchopanza's answer a bit...

for (int i=0; i=((Main.size())-1); i++) {
    cout << Main[i] << '\n';
}

does this:

1. Create i and set it to 0.
2. Set i to Main.size() - 1. Since Main is empty, Main.size() is 0, and i gets set to -1.
3. Main[-1] is an out-of-bounds access. Kaboom.

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

Why not do it for the entire page. At page load detect all images and continuously rotate all of them.

Some options to overlap rotations, borders are also added

MySQL can index the first x characters of a column,but a TEXT type is of variable length so mysql cant assure the uniqueness of the column.If you still want text column,use VARCHAR.

Given a p12 file with both the certificate and the private key (generated by openssl, for example), the following code will use that for a specific HttpsURLConnection:

    KeyStore keyStore = KeyStore.getInstance("pkcs12");
    keyStore.load(new FileInputStream(keyStorePath), keystorePassword.toCharArray());
    KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kmf.init(keyStore, keystorePassword.toCharArray());
    SSLContext ctx = SSLContext.getInstance("TLS");
    ctx.init(kmf.getKeyManagers(), null, null);
    SSLSocketFactory sslSocketFactory = ctx.getSocketFactory();

    HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
    connection.setSSLSocketFactory(sslSocketFactory);

The SSLContext takes some time to initialize, so you might want to cache it.

To update each submodule, you could invoke the following command (at the root of the repository):

git submodule -q foreach git pull -q origin master

You can remove the -q option to follow the whole process.

Change database to single user mode as shown in the other answers

Sometimes, even after converting to single user mode, the only connection allowed to the database may be in use.

To close a connection even after converting to single user mode try:

select * from master.sys.sysprocesses
where spid>50 -- don't want system sessions
  and dbid = DB_ID('BOSEVIKRAM')

Look at the results and see the ID of the connection to the database in question.

Then use the command below to close this connection (there should only be one since the database is now in single user mode)

KILL connection_ID

Replace connection_id with the ID in the results of the 1st query

This theme required awhile to find results and reasons:

using MaiaDB 5.4. via SuSE-LINUX tumblweed

1. some files in the appointed directory havn't been necessary in any direct relation with mariadb. I.e: I placed some hints, a text-file, some bakup-copys somewhere in the same appointed directory for mysql mariadb and this caused endless error-messages and blocking the server from starting. Mariadb appears to be very sensible and hostile with the presence of other files not beeing database files(comments,backups,experimantal files etc) .

2. using libreoffice as client then there already this generated much problems with the creation and working on a database and caused some crashes.The crashes eventually produced bad tables.

3. May be because of that or may be because of the presence of not yet deleted but unusable tables !! the mysql mariadb server crashed and didn't want to do it' job not even start.

Error message always same : "Table 'some.table' doesn't exist in engine"

But when it started then tables appeared as normal, but it was unpossible to work on them.

So what to do without a more precise Error Message ?? The unusable tables showed up with: "CHECK TABLE" or on the command line of the system with "mysqlcheck " So I deleted by filemanager or on the system-level as root or as allowed user all the questionable files and then problem was solved.

Proposal: the Error Message could be a bit more precisely for example: "corrupted tables" (which can be found by CHECK TABLE, but only if the server is running) or by mysqlcheck even whe server is not running - but here are other disturbing files like hints/bakups a.s.o not visible.

ANYWAY it helped a lot to have backup-copies of the original database-files on a backup volume. This helped to check out and test it again and again until solution was found.

Good luck all - Herbert

In my somewhat checkered experience, applying -O3 to an entire program almost always makes it slower (relative to -O2), because it turns on aggressive loop unrolling and inlining that make the program no longer fit in the instruction cache. For larger programs, this can also be true for -O2 relative to -Os!

The intended use pattern for -O3 is, after profiling your program, you manually apply it to a small handful of files containing critical inner loops that actually benefit from these aggressive space-for-speed tradeoffs. Newer versions of GCC have a profile-guided optimization mode that can (IIUC) selectively apply the -O3 optimizations to hot functions -- effectively automating this process.

if you need the batch file to schedule the backup, the SQL management tools have scheduled tasks built in...

DateTime.remove({}, callback) The empty object will match all of them.

None of the existing answers here has provided a complete example of how to do this from within a script (not a one-liner). Here is what I did:

rename($file, $file.'.bak');
open(IN, '<'.$file.'.bak') or die $!;
open(OUT, '>'.$file) or die $!;
while(<IN>)
{
    $_ =~ s/blue/red/g;
    print OUT $_;
}
close(IN);
close(OUT);

in case you do not only need to undo your last query (although your question actually only points on that, I know) and therefore if a transaction might not help you out, you need to implement a workaround for this:

copy the original data before commiting your query and write it back on demand based on the unique id that must be the same in both tables; your rollback-table (with the copies of the unchanged data) and your actual table (containing the data that should be "undone" than). for databases having many tables, one single "rollback-table" containing structured dumps/copies of the original data would be better to use then one for each actual table. it would contain the name of the actual table, the unique id of the row, and in a third field the content in any desired format that represents the data structure and values clearly (e.g. XML). based on the first two fields this third one would be parsed and written back to the actual table. a fourth field with a timestamp would help cleaning up this rollback-table.

since there is no real undo in SQL-dialects despite "rollback" in a transaction (please correct me if I'm wrong - maybe there now is one), this is the only way, I guess, and you have to write the code for it on your own.

Ruby automatically converts integers to a large integer class when they overflow, so there's (practically) no limit to how big they can be.

If you are looking for the machine's size, i.e. 64- or 32-bit, I found this trick at ruby-forum.com:

machine_bytes = ['foo'].pack('p').size
machine_bits = machine_bytes * 8
machine_max_signed = 2**(machine_bits-1) - 1
machine_max_unsigned = 2**machine_bits - 1

If you are looking for the size of Fixnum objects (integers small enough to store in a single machine word), you can call 0.size to get the number of bytes. I would guess it should be 4 on 32-bit builds, but I can't test that right now. Also, the largest Fixnum is apparently 2**30 - 1 (or 2**62 - 1), because one bit is used to mark it as an integer instead of an object reference.

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

PostgreSql is very advanced when related to logging techniques

Logs are stored in Installationfolder/data/pg_log folder. While log settings are placed in postgresql.conf file.

Log format is usually set as stderr. But CSV log format is recommended. In order to enable CSV format change in

log_destination = 'stderr,csvlog'   
logging_collector = on

In order to log all queries, very usefull for new installations, set min. execution time for a query

log_min_duration_statement = 0

In order to view active Queries on your database, use

SELECT * FROM pg_stat_activity

To log specific queries set query type

log_statement = 'all'           # none, ddl, mod, all

For more information on Logging queries see PostgreSql Log.

I spent more time on this than I should have, and haven't tested in IE for obvious reasons. That being said, it's pretty much identical.

http://jsfiddle.net/adzFe/14/

a.boxclose{
    float:right;
    margin-top:-30px;
    margin-right:-30px;
    cursor:pointer;
    color: #fff;
    border: 1px solid #AEAEAE;
    border-radius: 30px;
    background: #605F61;
    font-size: 31px;
    font-weight: bold;
    display: inline-block;
    line-height: 0px;
    padding: 11px 3px;       
}

.boxclose:before {
    content: "×";
}

Here the query:

Same Table:

UPDATE table_name 
SET column1 = column2

Different Table:

UPDATE table_name1 
    SET column1 = (
        SELECT column2
        FROM table_name2
        WHERE table_name1.id = table_name2.id
    );

Use this code:

internal void SomeFunction() {
    Dictionary<string, string> formField = new Dictionary<string, string>();
    
    formField.Add("Name", "Henry");
    formField.Add("Age", "21");
    
    string body = GetBodyStringFromDictionary(formField);
    // output : Name=Henry&Age=21
}

internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
    string body = string.Empty;
    foreach (var pair in formField)
    {
        body += $"{pair.Key}={pair.Value}&";   
    }

    // delete last "&"
    body = body.Substring(0, body.Length - 1);

    return body;
}

Java 10 did get local variable type inference, so now it has var which is pretty much equivalent to the C# one (so far as I am aware).

It can also infer non-denotable types (types which couldn't be named in that place by the programmer; though which types are non-denotable is different). See e.g. Tricks with var and anonymous classes (that you should never use at work).

The one difference I could find is that in C#,

If a type named var is in scope, then the var keyword will resolve to that type name and will not be treated as part of an implicitly typed local variable declaration.

In Java 10 var is not a legal type name.

We can achieve thread safety by using ConcurrentHashMap and synchronisedHashmap and Hashtable. But there is a lot of difference if you look at their architecture.

1. synchronisedHashmap and Hashtable

Both will maintain the lock at the object level. So if you want to perform any operation like put/get then you have to acquire the lock first. At the same time, other threads are not allowed to perform any operation. So at a time, only one thread can operate on this. So the waiting time will increase here. We can say that performance is relatively low when you comparing with ConcurrentHashMap.

2. ConcurrentHashMap

It will maintain the lock at segment level. It has 16 segments and maintains the concurrency level as 16 by default. So at a time, 16 threads can be able to operate on ConcurrentHashMap. Moreover, read operation doesn't require a lock. So any number of threads can perform a get operation on it.

If thread1 wants to perform put operation in segment 2 and thread2 wants to perform put operation on segment 4 then it is allowed here. Means, 16 threads can perform update(put/delete) operation on ConcurrentHashMap at a time.

So that the waiting time will be less here. Hence the performance is relatively better than synchronisedHashmap and Hashtable.

I wrote a PowerShell module that has native wrappers for MKLINK. https://gist.github.com/2891103

Includes functions for:

• New-Symlink
• New-HardLink
• New-Junction

Captures the MKLINK output and throws proper PowerShell errors when necessary.

You can do like this

SELECT something
FROM
    (a LEFT JOIN b ON a.a_id = b.b_id) LEFT JOIN c on a.a_aid = c.c_id
WHERE a.parent_id = 'rootID'

Note that if you're using Sublime as your commit editor, you need the -n -w flags, otherwise git keeps thinking your commit message is empty and aborting.

try this for your button:

<input type="button" class="my_button" name="buttonName" value="buttonValue" />

To do it without using a JavaScript library such as jQuery, you'd do it like this:

var span = document.getElementById("myspan"),
    text = document.createTextNode(''+intValue);
span.innerHTML = ''; // clear existing
span.appendChild(text);

If you do want to use jQuery, it's just this:

$("#myspan").text(''+intValue);

If you have several threads executing the methods m1 and m2 in the code below:

class SomeClass {
    private int i = 0;

    public void m1() { i = 5; }
    public int m2() { return i; }
}

you have the guarantee that any thread calling m2 will either read 0 or 5.

On the other hand, with this code (where i is a long):

class SomeClass {
    private long i = 0;

    public void m1() { i = 1234567890L; }
    public long m2() { return i; }
}

a thread calling m2 could read 0, 1234567890L, or some other random value because the statement i = 1234567890L is not guaranteed to be atomic for a long (a JVM could write the first 32 bits and the last 32 bits in two operations and a thread might observe i in between).

Here's what I had (file is already assigned to the path to the file with the source code in both examples):

execfile(file)

Here's what I replaced it with:

exec(compile(open(file).read(), file, 'exec'))

My favorite part: the second version works just fine in both Python 2 and 3, meaning it's not necessary to add in version dependent logic.

This should help:

if(screen.width<1026){//get the screen width
   //get element form document
   elem.style.display == 'none'//toggle visibility
}

768 px should be enough as well

I have in this moment install the bs4 with python 3.6.3 on Windows.

C:\yourfolderx\yourfoldery>python.exe -m pip install bs4

with the syntax like the user post below:

I just successfully installed a package for excel. After installing the python 3.6, you have to download the desired package, then install. For eg,

python.exe -m pip download openpyxl==2.1.4

python.exe -m pip install openpyxl==2.1.4

Try this

typeof(IFoo).IsAssignableFrom(typeof(BarClass));

This will tell you whether BarClass(Derived) implements IFoo(SomeType) or not
