I wasted a few frustrating hours on this problem too. We had to update our version of the .NET Framework, and started getting multiple “Could not load file or assembly or one of its dependencies” for several DLLs that had not been changed for years. Strangely, the versions being searched for in the error messages were all extremely old. For example, it was searching for Newtonsoft.Json version 6.0.0 while we had been using 8.0.1 for years.

Reverting to these ancient versions was not an option, and anyway there were a bunch of bindingRedirect elements in our web.config file that were supposed to redirect calls to old DLLs to the new ones. Rolling back the .NET version made the errors go away, but we needed the new version. What is going on?

The <runtime> element in our web.config file contained the element:

<assemblyBinding appliesTo="v2.0.50727"
    xmlns="urn:schemas-microsoft-com:asm.v1">

The dependentAssembly elements that seemed to be ignored were contained in that.

The culprit was the appliesTo attribute. It meant the bindingRedirect applies only to .NET version 2.0.50727. When we updated the .NET Framework version, all our bindingRedirect elements were ignored.

The solution in our case was to remove the appliesTo attribute entirely.

You could also use:

request.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials; 

After a lot of trial and error, followed by a stagnant period while I waited for an opportunity to speak with our server guys, I finally had a chance to discuss the problem with them and asked them if they wouldn't mind switching our Sharepoint authentication over to Kerberos.

To my surprise, they said this wouldn't be a problem and was in fact easy to do. They enabled Kerberos and I modified my app.config as follows:

<security mode="Transport">
    <transport clientCredentialType="Windows" />
</security>

For reference, my full serviceModel entry in my app.config looks like this:

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="TestServerReference" closeTimeout="00:01:00" openTimeout="00:01:00"
             receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
             bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
             maxBufferSize="2000000" maxBufferPoolSize="2000000" maxReceivedMessageSize="2000000"
             messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
             useDefaultWebProxy="true">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                 maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <security mode="Transport">
                    <transport clientCredentialType="Windows" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="https://path/to/site/_vti_bin/Lists.asmx"
         binding="basicHttpBinding" bindingConfiguration="TestServerReference"
         contract="TestServerReference.ListsSoap" name="TestServerReference" />
    </client>
</system.serviceModel>

After this, everything worked like a charm. I can now (finally!) utilize Sharepoint Web Services. So, if anyone else out there can't get their Sharepoint Web Services to work with NTLM, see if you can convince the sysadmins to switch over to Kerberos.

What worked for me is moving my project as it was on the desktop (C:\Users\lachezar.l\Desktop\MyFolder) to (C:\0\MyFolder) which as you can see uses shorter path and reducing it solved the problem.

Try this, pick or create one column and make that value required so that it's always populated such as title. A field that doesn't hold the name of the folder. Then in your filter put the filter you wanted that will select only the files you want. Then add an or to your filter, select your "required" field then set it equal to and leave the filter blank. Since all folders will have a blank in this required field your folders will show up with your files.

You can try U2U Query Builder http://www.u2u.net/res/Tools/CamlQueryBuilder.aspx you can use their API U2U.SharePoint.CAML.Server.dll and U2U.SharePoint.CAML.Client.dll

I didn't use them but I'm sure it will help you achieving your task.

To get current user info:

jQuery.ajax({
    url: _spPageContextInfo.webServerRelativeUrl + "/_api/web/currentuser",
    type: "GET",
    headers: { "Accept": "application/json;odata=verbose" }
}).done(function( data ){
    console.log( data );
    console.log( data.d.Title );
}).fail(function(){
    console.log( failed );
});

Make sure that the table you are returning has a schema. If not, then create a default schema (i.e. add a column in that table).

Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?

Something like request.Credentials = new NetworkCredential("UserName", "PassWord");

Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;

To further expand on Simon Johnsons post - Ideally you want a solution that will simulate the conditions you will see in production and modifying your code won't do that and could be dangerous if you forget to take the code out before you deploy it.

You will need a self-signed certificate of some sort. If you're using IIS Express you will have one of these already, you'll just have to find it. Open Firefox or whatever browser you like and go to your dev website. You should be able to view the certificate information from the URL bar and depending on your browser you should be able to export the certificate to a file.

Next, open MMC.exe, and add the Certificate snap-in. Import your certificate file into the Trusted Root Certificate Authorities store and that's all you should need. It's important to make sure it goes into that store and not some other store like 'Personal'. If you're unfamiliar with MMC or certificates, there are numerous websites with information how to do this.

Now, your computer as a whole will implicitly trust any certificates that it has generated itself and you won't need to add code to handle this specially. When you move to production it will continue to work provided you have a proper valid certificate installed there. Don't do this on a production server - that would be bad and it won't work for any other clients other than those on the server itself.

Installing the Chrome extension IE Tab did the job for me.

It has the ability to auto-detect URLs so whenever I browse to our SharePoint it emulates Internet Explorer. Finally I can open Office documents directly from Chrome.

You can install IETab for FireFox too.

As for second question - you can use Fiddler filters to set response X-Frame-Options header manually to something like ALLOW-FROM *. But, of course, this trick will work only for you - other users still won't be able to see iframe content(if they not do the same).

Best way to solve this until a fix is available (if a fix comes) is to force IE compatibility mode on the user.

Use <META http-equiv="X-UA-Compatible" content="IE=9"> ideally in the masterpage so all pages in your site get the workaround.

I messed around with this problem for a bit, and found a very simple, 2-line solution, simply replacing the 'http' and all the forward slashes like this:

myFilePath = replace(myFilePath, "/", "\")
myFilePath = replace(myFilePath, "http:", "")

It might not work for everybody, but it worked for me

If you are using a secure site (or wish to cater for both) you may wish to add the following line:

myFilePath = replace(myFilePath, "https:", "")

So I am not sure I can really think of why you would actually need a "site collection unique" id, so maybe you can comment and let us know what is actually trying to be accomplished here...

Either way, all items have a UniqueID property that is a GUID if you really need it: http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.splistitem.uniqueid.aspx

I encountered similar issue when uploading a file returned 409.

Besides issues mentioned above it can also happen due to file size restrictions for POST on the server side. For example, tomcat (java web server) have POST size limit of 2MB by default.

I think this need to be run from the Management Shell rather than the console, it sounds like the module isn't being imported into the Powershell console. You can add the module by running:

Add-PSSnapin Microsoft.Sharepoint.Powershell

in the Powershell console.

File: logdate.aspx

<%@ Page Language="c#" %>
<%@ Import namespace="System.IO"%>
<%

StreamWriter tsw = File.AppendText(@Server.MapPath("./test.txt"));
tsw.WriteLine("--------------------------------");
tsw.WriteLine(DateTime.Now.ToString());

tsw.Close();
%>

Done

Go to view all content of the site (http://yourdmain.sharepoint/sitename/_layouts/viewlsts.aspx). Select the document library "Pages" (the "Pages" library are named based on the language you created the site in. I.E. in norwegian the library is named "Sider"). Download the default.aspx to you computer and fix it (remove the web part and the <%Register tag). Save it and upload it back to the library (remember to check in the file).

EDIT:

ahh.. you are not using a publishing site template. Go to site action -> site settings. Under "site administration" select the menu "content and structure" you should now see your default.aspx page. But you cant do much with it...(delete, copy or move)

workaround: Enable publishing feature to the root web. Add the fixed default.aspx file to the Pages library and change the welcome page to this. Disable the publishing feature (this will delete all other list create from this feature but not the Pages library since one page is in use.). You will now have a new default.aspx page for the root web but the url is changed from sitename/default.aspx to sitename/Pages/default.aspx.

workaround II Use a feature to change the default.aspx file. The solution is explained here: http://wssguy.com/blogs/dan/archive/2008/10/29/how-to-change-the-default-page-of-a-sharepoint-site-using-a-feature.aspx

As an alternative to the webservices, you can use the put document call from the FrontPage RPC API. This has the additional benefit of enabling you to provide meta-data (columns) in the same request as the file data. The obvious drawback is that the protocol is a bit more obscure (compared to the very well documented webservices).

For a reference application that explains the use of Frontpage RPC, see the SharePad project on CodePlex.

This is how it was on the Microsoft site, with me just tweaking the SPSite and SPWeb since these might vary from environment to environment and it helps not to have to hard-code these:

using (SPSite oSiteCollection = new SPSite(SPContext.Current.Site.Url))
{
    using (SPWeb oWeb = oSiteCollection.OpenWeb(SPContext.Current.Web))
    {
        SPList oList = oWeb.Lists["Announcements"];
        // You may also use 
        // SPList oList = oWeb.GetList("/Lists/Announcements");
        // to avoid querying all of the sites' lists
        SPListItem oListItem = oList.Items.Add();
        oListItem["Title"] = "My Item";
        oListItem["Created"] = new DateTime(2004, 1, 23);
        oListItem["Modified"] = new DateTime(2005, 10, 1);
        oListItem["Author"] = 3;
        oListItem["Editor"] = 3;
        oListItem.Update();
    }
}

i couldn't change the permissions on the sharepoint i'm using but got a round it by uploading .url files with the drag and drop multiple files uploader.

Using the normal upload didn't work because they are intepreted by the file open dialog when you try to open them singly so it just tries to open the target not the .url file.

.url files can be made by saving a favourite with internet exploiter.

The same instance for SP2010; the Links List webpart will not automatically open in a new window, rather user must manually rt click Link object and select Open in New Window.

The add/ insert Link option withkin SP2010 will allow a user to manually configure the link to open in a new window.

Maybe SP2012 release will adrress this...

Pass Today as value as mentioned below in $viewQuery property :

$web = Get-SPWeb "http://sitename"
$list = $web.Lists.TryGetList($listtitle)
write-host "Exporting '$($list.Title)' data from '$($web.Title)' site.."
$viewTitle = "Program Events" #Title property
#Add the column names from the ViewField property to a string collection
$viewFields = New-Object System.Collections.Specialized.StringCollection
$viewFields.Add("Event Date") > $null
$viewFields.Add("Title") > $null
#Query property
$viewQuery = "<Where><Geq><FieldRef Name='EventDate' /><Value IncludeTimeValue='TRUE' Type='DateTime'><Today/></Value></Geq></Where><OrderBy><FieldRef Name='EventDate' Ascending='True' /></OrderBy>"
#RowLimit property
$viewRowLimit = 30
#Paged property
$viewPaged = $true
#DefaultView property
$viewDefaultView = $false
#Create the view in the destination list
$newview = $list.Views.Add($viewTitle, $viewFields, $viewQuery, $viewRowLimit, $viewPaged, $viewDefaultView)
Write-Host ("View '" + $newview.Title + "' created in list '" + $list.Title + "' on site " + $web.Url)
$web.Dispose()

Yes you can. I've used it with Word and PowerPoint. You will need Office 2010 client apps and SharePoint 2010 foundation at least. You must also allow editing without checking out on the document library.

It's quite cool, you can mark regions as 'locked' so no-one can change them and you can see what other people have changed every time you save your changes to the server. You also get to see who's working on the document from the Office app. The merging happens on SharePoint 2010.

Note that one difference between git remote --prune and git fetch --prune is being fixed, with commit 10a6cc8, by Tom Miller (tmiller) (for git 1.9/2.0, Q1 2014):

When we have a remote-tracking branch named "frotz/nitfol" from a previous fetch, and the upstream now has a branch named "**frotz"**, fetch would fail to remove "frotz/nitfol" with a "git fetch --prune" from the upstream.
git would inform the user to use "git remote prune" to fix the problem.

So: when a upstream repo has a branch ("frotz") with the same name as a branch hierarchy ("frotz/xxx", a possible branch naming convention), git remote --prune was succeeding (in cleaning up the remote tracking branch from your repo), but git fetch --prune was failing.

Not anymore:

Change the way "fetch --prune" works by moving the pruning operation before the fetching operation.
This way, instead of warning the user of a conflict, it automatically fixes it.

Probably the browser first downloaded the validade script and then jQuery. If the validade script be downloaded before loading jQuery you'll get an error. You can see this using a tool like firebug.

Try this:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script>
    function LoadValidade() {
        var a = false;
        try {
            var teste = $('*');
            if(teste == null)
                throw 1;
        } catch (e) { 
            a = true; 
        }

        if (a){ 
            setTimeout(LoadValidade, 300);
            return;
        }

        var validadeScript = document.createElement("script");
        validadeScript.src = "../common/jquery.validate.js";
        $('head')[0].appendChild(validadeScript);
    } 
    setTimeout(LoadValidade, 300);
</script>

I've had a similar problem for the last few days. For me the cause was a combination of systemd, docker and my hosting provider. I'm running up-to-date CentOS (7.7.1908).

My hosting provider automatically generates a config file for systemd-networkd. Starting with systemd 219 which is the current version for CentOS 7, systemd-networkd took control of network-related sysctl parameters. Docker seems to be incompatible with this version and will reset the IP-Forwarding flags everytime a container is launched.

My solution was to add IPForward=true in the [Network]-section of my provider-generated config file. This file might be in several places, most likely in /etc/systemd/network.

The process is also described in the official docker docs: https://docs.docker.com/v17.09/engine/installation/linux/linux-postinstall/#ip-forwarding-problems

In windows, type rmdir .git or rmdir /s .git if the .git folder has subfolders.

If your git shell isn't setup with proper administrative rights (i.e. it denies you when you try to rmdir), you can open a command prompt (possibly as administrator--hit the windows key, type 'cmd', right click 'command prompt' and select 'run as administrator) and try the same commands.

rd is an alternative form of the rmdir command. http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/rmdir.mspx?mfr=true

@Golmaal really answered this, I'm just being a bit more verbose.

<style type="text/css">
    #warning-message { display: none; }
    @media only screen and (orientation:portrait){
        #wrapper { display:none; }
        #warning-message { display:block; }
    }
    @media only screen and (orientation:landscape){
        #warning-message { display:none; }
    }
</style>

....

<div id="wrapper">
    <!-- your html for your website -->
</div>
<div id="warning-message">
    this website is only viewable in landscape mode
</div>

You have no control over the user moving the orientation however you can at least message them. This example will hide the wrapper if in portrait mode and show the warning message and then hide the warning message in landscape mode and show the portrait.

I don't think this answer is any better than @Golmaal , only a compliment to it. If you like this answer, make sure to give @Golmaal the credit.

Update

I've been working with Cordova a lot recently and it turns out you CAN control it when you have access to the native features.

Another Update

So after releasing Cordova it is really terrible in the end. It is better to use something like React Native if you want JavaScript. It is really amazing and I know it isn't pure web but the pure web experience on mobile kind of failed.

I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false} property for window.addEventListener, which is recommended as the only working solution, for example here.

In the end, after many tries, I found a way that works for me in both Firefox and Chrome:

window.addEventListener('keydown', (e) => {
    if (e.target.localName != 'input') {   // if you need to filter <input> elements
        switch (e.keyCode) {
            case 37: // left
            case 39: // right
                e.preventDefault();
                break;
            case 38: // up
            case 40: // down
                e.preventDefault();
                break;
            default:
                break;
        }
    }
}, {
    capture: true,   // this disables arrow key scrolling in modern Chrome
    passive: false   // this is optional, my code works without it
});

Quote for EventTarget.addEventListener() from MDN

options Optional
   An options object specifies characteristics about the event listener. The available options are:

capture
   A Boolean indicating that events of this type will be dispatched to the registered listener before being dispatched to any EventTarget beneath it in the DOM tree.
once
   ...
passive
   A Boolean that, if true, indicates that the function specified by listener will never call preventDefault(). If a passive listener does call preventDefault(), the user agent will do nothing other than generate a console warning. ...

You can better achieve it by using the DrawableCompat like this:

Drawable backgroundDrawable = view.getBackground();             
DrawableCompat.setTint(backgroundDrawable, newColor);

Using requests and json makes it simple.

1. Call the API
2. Assuming the API returns a JSON, parse the JSON object into a Python dict using json.loads function
3. Loop through the dict to extract information.

Requests module provides you useful function to loop for success and failure.

if(Response.ok): will help help you determine if your API call is successful (Response code - 200)

Response.raise_for_status() will help you fetch the http code that is returned from the API.

Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.

#Python 2.7.6
#RestfulClient.py

import requests
from requests.auth import HTTPDigestAuth
import json

# Replace with the correct URL
url = "http://api_url"

# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)

# For successful API call, response code will be 200 (OK)
if(myResponse.ok):

    # Loading the response data into a dict variable
    # json.loads takes in only binary or string variables so using content to fetch binary content
    # Loads (Load String) takes a Json file and converts into python data structure (dict or list, depending on JSON)
    jData = json.loads(myResponse.content)

    print("The response contains {0} properties".format(len(jData)))
    print("\n")
    for key in jData:
        print key + " : " + jData[key]
else:
  # If response code is not ok (200), print the resulting http error code with description
    myResponse.raise_for_status()

You could create Util class:

public final class CollectionHelpers {
    public static <T> boolean addNullSafe(List<T> list, T element) {
        if (list == null || element == null) {
            return false;
        }

        return list.add(element);
    }
}

And then use it:

Element element = getElementFromSomeWhere(someParameter);
List<Element> arrayList = new ArrayList<>();
CollectionHelpers.addNullSafe(list, element);

The deprecated low_memory option

The low_memory option is not properly deprecated, but it should be, since it does not actually do anything differently[source]

The reason you get this low_memory warning is because guessing dtypes for each column is very memory demanding. Pandas tries to determine what dtype to set by analyzing the data in each column.

Dtype Guessing (very bad)

Pandas can only determine what dtype a column should have once the whole file is read. This means nothing can really be parsed before the whole file is read unless you risk having to change the dtype of that column when you read the last value.

Consider the example of one file which has a column called user_id. It contains 10 million rows where the user_id is always numbers. Since pandas cannot know it is only numbers, it will probably keep it as the original strings until it has read the whole file.

Specifying dtypes (should always be done)

adding

dtype={'user_id': int}

to the pd.read_csv() call will make pandas know when it starts reading the file, that this is only integers.

Also worth noting is that if the last line in the file would have "foobar" written in the user_id column, the loading would crash if the above dtype was specified.

Example of broken data that breaks when dtypes are defined

import pandas as pd
try:
    from StringIO import StringIO
except ImportError:
    from io import StringIO


csvdata = """user_id,username
1,Alice
3,Bob
foobar,Caesar"""
sio = StringIO(csvdata)
pd.read_csv(sio, dtype={"user_id": int, "username": "string"})

ValueError: invalid literal for long() with base 10: 'foobar'

dtypes are typically a numpy thing, read more about them here: http://docs.scipy.org/doc/numpy/reference/generated/numpy.dtype.html

What dtypes exists?

We have access to numpy dtypes: float, int, bool, timedelta64[ns] and datetime64[ns]. Note that the numpy date/time dtypes are not time zone aware.

Pandas extends this set of dtypes with its own:

'datetime64[ns, ]' Which is a time zone aware timestamp.

'category' which is essentially an enum (strings represented by integer keys to save

'period[]' Not to be confused with a timedelta, these objects are actually anchored to specific time periods

'Sparse', 'Sparse[int]', 'Sparse[float]' is for sparse data or 'Data that has a lot of holes in it' Instead of saving the NaN or None in the dataframe it omits the objects, saving space.

'Interval' is a topic of its own but its main use is for indexing. See more here

'Int8', 'Int16', 'Int32', 'Int64', 'UInt8', 'UInt16', 'UInt32', 'UInt64' are all pandas specific integers that are nullable, unlike the numpy variant.

'string' is a specific dtype for working with string data and gives access to the .str attribute on the series.

'boolean' is like the numpy 'bool' but it also supports missing data.

Read the complete reference here:

Pandas dtype reference

Gotchas, caveats, notes

Setting dtype=object will silence the above warning, but will not make it more memory efficient, only process efficient if anything.

Setting dtype=unicode will not do anything, since to numpy, a unicode is represented as object.

Usage of converters

@sparrow correctly points out the usage of converters to avoid pandas blowing up when encountering 'foobar' in a column specified as int. I would like to add that converters are really heavy and inefficient to use in pandas and should be used as a last resort. This is because the read_csv process is a single process.

CSV files can be processed line by line and thus can be processed by multiple converters in parallel more efficiently by simply cutting the file into segments and running multiple processes, something that pandas does not support. But this is a different story.

This should be working too using JPA 2.0 @MapsId annotation instead of Hibernate's GenericGenerator:

@Entity
public class Person {

    @Id
    @GeneratedValue
    public int id;

    @OneToOne
    @PrimaryKeyJoinColumn
    public OtherInfo otherInfo;

    rest of attributes ...
}

@Entity
public class OtherInfo {

    @Id
    public int id;

    @MapsId
    @OneToOne
    @JoinColumn(name="id")
    public Person person;

    rest of attributes ...
}

More details on this in Hibernate 4.1 documentation under section 5.1.2.2.7.

I think not only is the question not clear but most people also are not cognizant of the difference. Examine the following saying,

POSIX thread IDs are not the same as the thread IDs returned by the Linux specific gettid() system call. POSIX thread IDs are assigned and maintained by the threading implementation. The thread ID returned by gettid() is a number (similar to a process ID) that is assigned by the kernel. Although each POSIX thread has a unique kernel thread ID in the Linux NPTL threading implementation, an application generally doesn’t need to know about the kernel IDs (and won’t be portable if it depends on knowing them).

Excerpted from: The Linux Programming Interface: A Linux and UNIX System Programming Handbook, Michael Kerrisk

IMHO, there is only one portable way that pass a structure in which define a variable holding numbers in an ascending manner e.g. 1,2,3... to per thread. By doing this, threads' id can be kept track. Nonetheless, int pthread_equal(tid1, tid2) function should be used.

if (pthread_equal(tid1, tid2)) printf("Thread 2 is same as thread 1.\n");
else printf("Thread 2 is NOT same as thread 1.\n");

And what about:

if ($('#dataTable[data-timer]').length > 0) {
    // logic here
}

If you are using http://, as eyze suggested, you will only be able to read the ouput of the PHP script. You can only read the PHP script itself if it is on the same server as your running script. You could then use something like

$Vdata = file_get_contents('/path/to/your/file.php");

Try this out:

sudo ldconfig

sudo nano /etc/ld.so.conf.d/opencv.conf

and add this following line in the opencv.conf not in the command window

/usr/local/lib

Then:

sudo ldconfig

sudo nano /etc/bash.bashrc

and add this two lines in the bash.bashrc not in the command window

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig       
export PKG_CONFIG_PATH

at last reboot your Pi sudo reboot now

and try import cv2

<div id="calendar"></div>
<script>
$(document).ready(function() {
    var days = [];

    $('#calendar').datepicker({
        dateFormat: 'yymmdd',
        showWeek: true, showOtherMonths: false, selectOtherMonths: false,
        navigationAsDateFormat: true, prevText: 'MM', nextText: 'MM',
        onSelect: function(d) {
            var i = $.inArray(d, days);

            if (i == -1)
                days.push(d);
            else
                days.splice(i, 1);
        },
        beforeShowDay: function(d) {
            return ([true, $.inArray($.datepicker.formatDate('yymmdd', d), days) == -1 ? 'ui-state-free' : 'ui-state-busy']);
        }
    });
});
</script>

NOTE: You can prefill days with a list of dates like '20190101' with a piece of code in PHP.

Add 2 lines to your CSS:

#calendar .ui-state-busy a {background:#e6e6e6 !important;}
#calendar .ui-state-free a {background:none !important;}

To get the list of days selected by the calendar in a <form>:

<div id="calendar"></div>
<form method="post">
<input type="submit" name="calendar_get" id="calendar_get" value="Validate" />
</form>

Add this to the <script>:

    $('#calendar_get').click(function() {
        $(this).append('<input type="hidden" name="calendar_days" value="' + days.join(',') + '" />');
    });

Apply implode on the string in $_POST['calendar_days'] and map strtotime to all the formatted dates.

I found a not-very-intuitive way to do this by using DUMP()

SELECT DUMP(A.NAME), 
       DUMP(A.surname), 
       DUMP(B.ordernum) 
FROM   customer A 
       JOIN orders B 
         ON A.id = B.id

It will return something like:

'Typ=1 Len=2: 0,48' for each column.

Type=1 means VARCHAR2/NVARCHAR2
Type=2 means NUMBER/FLOAT
Type=12 means DATE, etc.

You can refer to this oracle doc for information Datatype Code
or this for a simple mapping Oracle Type Code Mappings

$('#google').attr('onclick') + ""

However, Firebug shows that this returns a function 'onclick'. You can call the function later on using the following approach:

(new Function ($('#google').attr('onclick') + ';onclick();'))()

... or use a RegEx to strip the function and get only the statements within it.

You don't, see below

I find this 'feature' rather annoying since I'm not trying to launch rockets to the moon, just push my damn branch. You probably do too or else you wouldn't be here!

Here is the fix: if you want it to implicitly push for the current branch regardless of if that branch exists on origin just issue this command once and you will never have to again anywhere:

git config --global push.default current

So if you make branches like this:

git checkout -b my-new-branch

and then make some commits and then do a

git push -u

to get them out to origin (being on that branch) and it will create said branch for you if it doesn't exist.

Note the -u bit makes sure they are linked if you were to pull later on from said branch. If you have no plans to pull the branch later (or are okay with another one liner if you do) -u is not necessary.

try appending sudo before whatever command you are trying.

like this : sudo npm install

Using sudo with a command in Linux/UNIX generally elevates your permissions to superuser levels. In Windows, the superuser account is usually called 'Administrator.' In Linux/Unix the superuser account is generally named 'root'.

The root user has permission to access, modify or delete almost any file on your computer. Normal user accounts can access, modify or delete many fewer files. The restrictions on a normal account protect your computer from unauthorized or harmful programs or users. Some processes require you to perform actions on files or folders you don't normally have permissions to access. Installing a program that everyone can access is one of these actions.

In your case, running the installation command with sudo gives you the permissions of the superuser, and allows you to modify files that your normal user doesn't have permission to modify.

This answer is an update with a little more consideration for OOM and various other leaks.

Assumes you have a directory intended as the destination and a name String already defined.

    File destination = new File(directory.getPath() + File.separatorChar + filename);

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    source.compress(Bitmap.CompressFormat.PNG, 100, bytes);

    FileOutputStream fo = null;
    try {
        destination.createNewFile();

        fo = new FileOutputStream(destination);
        fo.write(bytes.toByteArray());
    } catch (IOException e) {

    } finally {
        try {
            fo.close();
        } catch (IOException e) {}
    }

Assuming that your current primary key constraint is called pk_history, you can replace the following lines:

ALTER TABLE history ADD PRIMARY KEY (id)

ALTER TABLE history
DROP CONSTRAINT userId
DROP CONSTRAINT name

with these:

ALTER TABLE history DROP CONSTRAINT pk_history

ALTER TABLE history ADD CONSTRAINT pk_history PRIMARY KEY (id)

If you don't know what the name of the PK is, you can find it with the following query:

SELECT * 
  FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
 WHERE TABLE_NAME = 'history'

You are trying to execute the number in the ENDTIME as a command. You should also see an error like 1370306857: command not found. Instead use the arithmetic expansion:

echo "It takes $(($ENDTIME - $STARTTIME)) seconds to complete this task..."

You could also save the commands in a separate script, commands.sh, and use time command:

time commands.sh

I ran into this issue after updating the Java JDK, but had not yet restarted my command prompt. After restarting the command prompt, everything worked fine. Presumably, because the PATH variable need to be reset after the JDK update.

Neither Project/Properties/Javadoc Location nor Project/Properties/Java Build Path/Libraries had not helped me until I picked and moved up in "Order and Export" tab of "Java Build Path" "Android Dependencies" and added-in-library.jar. I hope it will be useful.

I found a better solution on the Chrome product forums by a user called Gary. The original thread is here.

Navigate to C:\Windows\System32\GroupPolicy

Open each subdirectory there and change the *.pol files to *.sav, E.g. registry.pol becomes registry.sav.

Hit Windows-Key + R, type the following in the box and hit enter

reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Google\Chrome

In the command promt window that opens type: Yes and press Enter.

Restart Google Chrome and check whether you can change the search engine.

iframe is also vulnerable to Cross Frame Scripting:

• https://www.owasp.org/index.php/Cross_Frame_Scripting

use textstyle property as bold

android:textStyle = "bold";

In Swift 3.0

extension String
{   
    func trim() -> String
   {
    return self.trimmingCharacters(in: CharacterSet.whitespaces)
   }
}

And you can call

let result = " Hello World ".trim()  /* result = "Hello World" */

The short answer is there's no great way to do this given the design you have. Here's a related question on the topic: Sum values of a single row?

If you normalized your schema and created a separate table called "Marks" which had a subject_id and a mark column this would allow you to take advantage of the SUM function as intended by a relational model.

Then your query would be

SELECT subject, SUM(mark) total 
FROM Subjects s 
  INNER JOIN Marks m ON m.subject_id = s.id
GROUP BY s.id

Like this

class CustomDictOne(dict):
   def __init__(self,*arg,**kw):
      super(CustomDictOne, self).__init__(*arg, **kw)

Now you can use the built-in functions, like dict.get() as self.get().

You do not need to wrap a hidden self._dict. Your class already is a dict.

In Ruby, the Windows version anyways, I just checked and __FILE__ does not contain the full path to the file. Instead it contains the path to the file relative to where it's being executed from.

In PHP __FILE__ is the full path (which in my opinion is preferable). This is why, in order to make your paths portable in Ruby, you really need to use this:

File.expand_path(File.dirname(__FILE__) + "relative/path/to/file")

I should note that in Ruby 1.9.1 __FILE__ contains the full path to the file, the above description was for when I used Ruby 1.8.7.

In order to be compatible with both Ruby 1.8.7 and 1.9.1 (not sure about 1.9) you should require files by using the construct I showed above.

You want to specify a custom tooltip template in your chart options, like this :

 // String - Template string for single tooltips
 tooltipTemplate: "<%if (label){%><%=label %>: <%}%><%= value + ' %' %>",
 // String - Template string for multiple tooltips
 multiTooltipTemplate: "<%= value + ' %' %>",

This way you can add a '%' sign after your values if that's what you want.

Here's a jsfiddle to illustrate this.

Note that tooltipTemplate applies if you only have one dataset, multiTooltipTemplate applies if you have several datasets.

This options are mentioned in the global chart configuration section of the documentation. Do have a look, it's worth checking for all the other options that can be customized in there.

Note that Your datasets should only contain numeric values. (No % signs or other stuff there).

1) Yes, a select with NOLOCK will complete faster than a normal select.

2) Yes, a select with NOLOCK will allow other queries against the effected table to complete faster than a normal select.

Why would this be?

NOLOCK typically (depending on your DB engine) means give me your data, and I don't care what state it is in, and don't bother holding it still while you read from it. It is all at once faster, less resource-intensive, and very very dangerous.

You should be warned to never do an update from or perform anything system critical, or where absolute correctness is required using data that originated from a NOLOCK read. It is absolutely possible that this data contains rows that were deleted during the query's run or that have been deleted in other sessions that have yet to be finalized. It is possible that this data includes rows that have been partially updated. It is possible that this data contains records that violate foreign key constraints. It is possible that this data excludes rows that have been added to the table but have yet to be committed.

You really have no way to know what the state of the data is.

If you're trying to get things like a Row Count or other summary data where some margin of error is acceptable, then NOLOCK is a good way to boost performance for these queries and avoid having them negatively impact database performance.

Always use the NOLOCK hint with great caution and treat any data it returns suspiciously.

I just found this built into Oracle 10g if that is what you're using. I had to strip all the special characters out for a phone number compare.

regexp_replace(c.phone, '[^0-9]', '')

You don't have a field named user_email in the members table ... as for why, I'm not sure as the code "looks" like it should try to join on different fields

Does the Auth::attempt method perform a join of the schema? Run grep -Rl 'class Auth' /path/to/framework and find where the attempt method is and what it does.

Can also see here on how to turn on MSDTC from the Control Panel's services.msc.

On the server where the trigger resides, you need to turn the MSDTC service on. You can this by clicking START > SETTINGS > CONTROL PANEL > ADMINISTRATIVE TOOLS > SERVICES. Find the service called 'Distributed Transaction Coordinator' and RIGHT CLICK (on it and select) > Start.

Declare your path:

PATH='/home/artemb'     
cd ${PATH}

You can use map. Here is an example implementation:

case 'SOME_ACTION':
   return { 
       ...state, 
       contents: state.contents.map(
           (content, i) => i === 1 ? {...content, text: action.payload}
                                   : content
       )
    }

You can pipe the output of type into find inside the in(…) clause of a for /f loop:

for /f %%A in ('
    type "%~dpf1" ^| find /c /v ""
') do set "lineCount=%%A"

But the pipe starts a subshell, which slows things down.

Or, you could redirect input from the file into find like so:

for /f %%A in ('
    find /c /v "" ^< "%~dpf1"
') do set "lineCount=%%A"

But this approach will give you an answer 1 less than the actual number of lines if the file ends with one or more blank lines, as teased out by the late foxidrive in counting lines in a file.

And then again, you could always try:

find /c /v "" example.txt

The trouble is, the output from the above command looks like this:

---------- EXAMPLE.TXT: 511

You could split the string on the colon to get the count, but there might be more than one colon if the filename had a full path.

Here’s my take on that problem:

for /f "delims=" %%A in ('
    find /c /v "" "%~1"
') do for %%B in (%%A) do set "lineCount=%%B"

This will always store the count in the variable.

Just one last little problem… find treats null characters as newlines. So if sneaky nulls crept into your text file, or if you want to count the lines in a Unicode file, this answer isn’t for you.

Node.js is an open source command line tool built for the server side JavaScript code.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

The basic philosophy of node.js is:

Non-blocking I/O - every I/O call must take a callback, whether it is to retrieve information from disk, network or another process. Built-in support for the most important protocols (HTTP, DNS, TLS) Low-level. Do not remove functionality present at the POSIX layer. For example, support half-closed TCP connections. Stream everything; never force the buffering of data.

The pyplot functions you are calling, axhline() and axvline() draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin or ymin use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.

Instead, use plt.plot((x1, x2), (y1, y2), 'k-') to draw a line from the point (x1, y1) to the point (x2, y2) in color k. See pyplot.plot.

Can i suggest http://www.jqueryscript.net/form/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest.html, works more like the twitter post suggestion where it gives you a list of users or topics based on @ or # tags,

view demo here: http://www.jqueryscript.net/demo/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest/

in this one you can easily change the @ and # to anything you want

There's another, simpler way to do this:

1. npm install Node@8 (saves Node 8 as dependency in package.json)
2. Your app will run using Node 8 for anyone - even Yarn users!

This works because node is just a package that ships node as its package binary. It just includes as node_module/.bin which means it only makes node available to package scripts. Not main shell.

With version 1.7 of the official 10gen driver, this is the current (non-obsolete) API:

const string uri = "mongodb://localhost/mydb";
var client = new MongoClient(uri);
var db = client.GetServer().GetDatabase(new MongoUrl(uri).DatabaseName);
var collection = db.GetCollection("mycollection");

This one worked the best for me:

    display: flex;
    justify-content: center;
    align-items: center;
    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;

While it is true that an object cannot be "empty/null" in C++, in C++17, we got std::optional to express that intent.

Example use:

std::optional<int> v1;      // "empty" int
std::optional<int> v2(3);   // Not empty, "contains a 3"

You can then check if the optional contains a value with

v1.has_value(); // false

or

if(v2) {
    // You get here if v2 is not empty
}

A plain int (or any type), however, can never be "null" or "empty" (by your definition of those words) in any useful sense. Think of std::optional as a container in this regard.

If you don't have a C++17 compliant compiler at hand, you can use boost.optional instead. Some pre-C++17 compilers also offer std::experimental::optional, which will behave at least close to the actual std::optional afaik. Check your compiler's manual for details.

Do you mean Delegate.Invoke/BeginInvoke or Control.Invoke/BeginInvoke?

• Delegate.Invoke: Executes synchronously, on the same thread.
• Delegate.BeginInvoke: Executes asynchronously, on a threadpool thread.
• Control.Invoke: Executes on the UI thread, but calling thread waits for completion before continuing.
• Control.BeginInvoke: Executes on the UI thread, and calling thread doesn't wait for completion.

Tim's answer mentions when you might want to use BeginInvoke - although it was mostly geared towards Delegate.BeginInvoke, I suspect.

For Windows Forms apps, I would suggest that you should usually use BeginInvoke. That way you don't need to worry about deadlock, for example - but you need to understand that the UI may not have been updated by the time you next look at it! In particular, you shouldn't modify data which the UI thread might be about to use for display purposes. For example, if you have a Person with FirstName and LastName properties, and you did:

person.FirstName = "Kevin"; // person is a shared reference
person.LastName = "Spacey";
control.BeginInvoke(UpdateName);
person.FirstName = "Keyser";
person.LastName = "Soze";

Then the UI may well end up displaying "Keyser Spacey". (There's an outside chance it could display "Kevin Soze" but only through the weirdness of the memory model.)

Unless you have this sort of issue, however, Control.BeginInvoke is easier to get right, and will avoid your background thread from having to wait for no good reason. Note that the Windows Forms team has guaranteed that you can use Control.BeginInvoke in a "fire and forget" manner - i.e. without ever calling EndInvoke. This is not true of async calls in general: normally every BeginXXX should have a corresponding EndXXX call, usually in the callback.

The standard function atoi() will likely do what you want.

A simple example using "atoi":

#include <unistd.h>

int main(int argc, char *argv[])
{
    int useconds = atoi(argv[1]); 
    usleep(useconds);
}

Alternatively you could just use a document.write:

<script type="text\javascript">
var loc = "http://";
document.write('<a href="' + loc + '">Link text</a>');
</script>

You can get to the parent node and then query all the nodes with the class that is being searched. then we get the size

var parent = document.getElementById("parentId");_x000D_
var nodesSameClass = parent.getElementsByClassName("test");_x000D_
console.log(nodesSameClass.length);

<div id="parentId">_x000D_
  <p class="prueba">hello word1</p>_x000D_
  <p class="test">hello word2</p>_x000D_
  <p class="test">hello word3</p>_x000D_
  <p class="test">hello word4</p>_x000D_
</div>

ffmpeg -i movie.mp4 -ss 00:00:03 -t 00:00:08 -async 1 -c copy cut.mp4 

Use -c copy for make in instantly. In that case ffmpeg will not re-encode video, just will cut to according size.

You could implement a onActivityResult in Class B as well and launch Class C using startActivityForResult. Once you get the result in Class B then set the result there (for Class A) based on the result from Class C. I haven't tried this out but I think this should work.

Another thing to look out for is that Activity A should not be a singleInstance activity. For startActivityForResult to work your Class B needs to be a sub activity to Activity A and that is not possible in a single instance activity, the new Activity (Class B) starts in a new task.

I have solved this problem by adding a UIControl to the navigationBar on the left side .

UIControl *leftBarItemControl = [[UIControl alloc] initWithFrame:CGRectMake(0, 0, 90, 44)];
[leftBarItemControl addTarget:self action:@selector(onLeftItemClick:) forControlEvents:UIControlEventTouchUpInside];
self.leftItemControl = leftBarItemControl;
[self.navigationController.navigationBar addSubview:leftBarItemControl];
[self.navigationController.navigationBar bringSubviewToFront:leftBarItemControl];

And you need to remember to remove it when view will disappear:

- (void) viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    if (self.leftItemControl) {
        [self.leftItemControl removeFromSuperview];
    }    
}

That's all!

Best to use ResultSet.next() along with the do {...} while() syntax for this.

The "check for any results" call ResultSet.next() moves the cursor to the first row, so use the do {...} while() syntax to process that row while continuing to process remaining rows returned by the loop.

This way you get to check for any results, while at the same time also processing any results returned.

if(resultSet.next()) { // Checks for any results and moves cursor to first row,
    do { // Use 'do...while' to process the first row, while continuing to process remaining rows

    } while (resultSet.next());
}

There are a couple issues here. First, you need to make sure to bind your JSON object back to the model in the controller. This is done by changing

data: JSON.stringify(usersRoles),

to

data: { model: JSON.stringify(usersRoles) },

Secondly, you aren't binding types correctly with your jquery call. If you remove

contentType: "application/json; charset=utf-8",

it will inherently bind back to a string.

All together, use the first ActionResult method and the following jquery ajax call:

    jQuery.ajax({
        type: "POST",
        url: "@Url.Action("AddUser")",
        dataType: "json",
        data: { model: JSON.stringify(usersRoles) },
        success: function (data) { alert(data); },
        failure: function (errMsg) {
        alert(errMsg);
        }
   });

Like this:

from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key

Or, using the method syntax:

Company
    .GroupBy(c => c.Name)
    .Where(grp => grp.Count() > 1)
    .Select(grp => grp.Key);

Take input from user:

input = int(input("enter a n value:"))

dict = {}

for i in range(input):

    name = input() 

    values = int(input()) 

    dict[name] = values
print(dict)

For a couple of years I was a supporter of using a specific .gitignore for IntelliJ with this suggested configuration.

Not anymore.

IntelliJ is updated quite frequently, internal config file specs change more often than I would like and JetBrains flagship excels at auto-configuring itself based on maven/gradle/etc build files.

So my suggestion would be to leave all editor config files out of project and have users configure editor to their liking. Things like code styling can and should be configured at build level; say using Google Code Style or CheckStyle directly on Maven/Gradle/sbt/etc.

This ensures consistency and leaves editor files out of source code that, in my personal opinion, is where they should be.

Try something like gem uninstall rjb --version 1.3.4.

All you need to give the name attribute to the each button. And you need to address each button press from the PHP script. But be careful to give each button a unique name. Because the PHP script only take care of the name most of the time

<input type="submit" name="Submit_this" id="This" />

You'll want something like this:

$("#next").click(function(){
      var currentElement = currentElement.next();
      $('html, body').animate({scrollLeft: $(currentElement).offset().left}, 800);
      return false;
   });

}

fields() and fieldNames() both were not working for me. And I had to spend quite sometime to find a way to iterate over the keys. There are two ways by which it can be done.

One is by converting it into a map (takes up more space):

ObjectMapper mapper = new ObjectMapper();
Map<String, Object> result = mapper.convertValue(jsonNode, Map.class);
for (String key : result.keySet())
{
    if(key.equals(foo))
    {
        //code here
    }
}

Another, by using a String iterator:

Iterator<String> it = jsonNode.getFieldNames();
while (it.hasNext())
{
    String key = it.next();
    if (key.equals(foo))
    {
         //code here
    }
}

If you are using LINUX, you can use pyALSAAUDIO. For windows, we have PyAudio and there is also a library called SoundAnalyse.

I found an example for Linux here:

#!/usr/bin/python
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm for sound capture. Set
## various attributes of the capture, and reads in a loop,
## Then prints the volume.
##
## To test it out, run it and shout at your microphone:

import alsaaudio, time, audioop

# Open the device in nonblocking capture mode. The last argument could
# just as well have been zero for blocking mode. Then we could have
# left out the sleep call in the bottom of the loop
inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)

# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
inp.setchannels(1)
inp.setrate(8000)
inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)

# The period size controls the internal number of frames per period.
# The significance of this parameter is documented in the ALSA api.
# For our purposes, it is suficcient to know that reads from the device
# will return this many frames. Each frame being 2 bytes long.
# This means that the reads below will return either 320 bytes of data
# or 0 bytes of data. The latter is possible because we are in nonblocking
# mode.
inp.setperiodsize(160)

while True:
    # Read data from device
    l,data = inp.read()
    if l:
        # Return the maximum of the absolute value of all samples in a fragment.
        print audioop.max(data, 2)
    time.sleep(.001)

I am reading a book (Effective Python) by Brett Slatkin and he shows another way to iterate over a list and also know the index of the current item in the list but he suggests that it is better not to use it and to use enumerate instead. I know you asked what enumerate means, but when I understood the following, I also understood how enumerate makes iterating over a list while knowing the index of the current item easier (and more readable).

list_of_letters = ['a', 'b', 'c']
for i in range(len(list_of_letters)):
    letter = list_of_letters[i]
    print (i, letter)

The output is:

0 a
1 b
2 c

I also used to do something, even sillier before I read about the enumerate function.

i = 0
for n in list_of_letters:
    print (i, n)
    i += 1

It produces the same output.

But with enumerate I just have to write:

list_of_letters = ['a', 'b', 'c']
for i, letter in enumerate(list_of_letters):
    print (i, letter)

foreach (DataGridViewRow row in datagrid.Rows)
                        row.HeaderCell.Value = String.Format("{0}", row.Index + 1);

Just add this in the .htaccess file:

DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]

Java Character class has an isLetterOrDigit method since version 1.0.2

there's another one not mentioned here - nice thin - if you need that kind of look for your project: ╳

╳ or decimal: ╳

If you're doing a lot of bit twiddling you might want to use masks which will make the whole thing quicker. The following functions are very fast and are still flexible (they allow bit twiddling in bit maps of any size).

const unsigned char TQuickByteMask[8] =
{
   0x01, 0x02, 0x04, 0x08,
   0x10, 0x20, 0x40, 0x80,
};


/** Set bit in any sized bit mask.
 *
 * @return    none
 *
 * @param     bit    - Bit number.
 * @param     bitmap - Pointer to bitmap.
 */
void TSetBit( short bit, unsigned char *bitmap)
{
    short n, x;

    x = bit / 8;        // Index to byte.
    n = bit % 8;        // Specific bit in byte.

    bitmap[x] |= TQuickByteMask[n];        // Set bit.
}


/** Reset bit in any sized mask.
 *
 * @return  None
 *
 * @param   bit    - Bit number.
 * @param   bitmap - Pointer to bitmap.
 */
void TResetBit( short bit, unsigned char *bitmap)
{
    short n, x;

    x = bit / 8;        // Index to byte.
    n = bit % 8;        // Specific bit in byte.

    bitmap[x] &= (~TQuickByteMask[n]);    // Reset bit.
}


/** Toggle bit in any sized bit mask.
 *
 * @return   none
 *
 * @param   bit    - Bit number.
 * @param   bitmap - Pointer to bitmap.
 */
void TToggleBit( short bit, unsigned char *bitmap)
{
    short n, x;

    x = bit / 8;        // Index to byte.
    n = bit % 8;        // Specific bit in byte.

    bitmap[x] ^= TQuickByteMask[n];        // Toggle bit.
}


/** Checks specified bit.
 *
 * @return  1 if bit set else 0.
 *
 * @param   bit    - Bit number.
 * @param   bitmap - Pointer to bitmap.
 */
short TIsBitSet( short bit, const unsigned char *bitmap)
{
    short n, x;

    x = bit / 8;    // Index to byte.
    n = bit % 8;    // Specific bit in byte.

    // Test bit (logigal AND).
    if (bitmap[x] & TQuickByteMask[n])
        return 1;

    return 0;
}


/** Checks specified bit.
 *
 * @return  1 if bit reset else 0.
 *
 * @param   bit    - Bit number.
 * @param   bitmap - Pointer to bitmap.
 */
short TIsBitReset( short bit, const unsigned char *bitmap)
{
    return TIsBitSet(bit, bitmap) ^ 1;
}


/** Count number of bits set in a bitmap.
 *

 * @param    size   - Bitmap size (in bits).
 *
 * @note    Not very efficient in terms of execution speed. If you are doing
 *        some computationally intense stuff you may need a more complex
 *        implementation which would be faster (especially for big bitmaps).
 *        See (http://graphics.stanford.edu/~seander/bithacks.html).
 */
int TCountBits( const unsigned char *bitmap, int size)
{
    int i, count = 0;

    for (i=0; i<size; i++)
        if (TIsBitSet(i, bitmap))
            count++;

    return count;
}

Note, to set bit 'n' in a 16 bit integer you do the following:

TSetBit( n, &my_int);

It's up to you to ensure that the bit number is within the range of the bit map that you pass. Note that for little endian processors that bytes, words, dwords, qwords, etc., map correctly to each other in memory (main reason that little endian processors are 'better' than big-endian processors, ah, I feel a flame war coming on...).

You neglected to say which version of C you are concerned about. Let's assume it's this one:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

As you can see by reading the specification, the standard definitions of true and false are 1 and 0, yes.

If your question is about a different version of C, or about non-standard definitions for true and false, then ask a more specific question.

document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';

You can use ComboBox, then point your mouse to the upper arrow facing right, it will unfold a box called ComboBox Tasks and in there you can go ahead and edit your items or fill in the items / strings one per line. This should be the easiest.

For what it's worth, with iOS7 dropping support for datetime you need to use datetime-local which doesn't accept timezone portion (which makes sense).

Doesn't work (iOS anyway):

 <input type="datetime-local" value="2000-01-01T00:00:00+05:00" />

Works:

<input type="datetime-local" value="2000-01-01T00:00:00" />

PHP for value (windows safe):

strftime('%Y-%m-%dT%H:%M:%S', strtotime($my_datetime_input))

Omit the parenthesis:

ALTER TABLE User 
    ADD CONSTRAINT userProperties
    FOREIGN KEY(properties)
    REFERENCES Properties(ID)

From office 2010, we won't be able to use the common dialog box control, so it's nice to use the Application object to get the desired results.

Here I got a text box and Command button - paste the following code under the command button click event, which will open the file dialog box and add the File name to the Text box.

Dim sFileName  As String

sFileName = Application.GetOpenFilename("MS Excel (*.xlsx), *.xls")

TextBox1.Text = sFileName

If your code needs to be compatible with both Python 2 and Python 3, you can't directly use things like isinstance(s,bytes) or isinstance(s,unicode) without wrapping them in either try/except or a python version test, because bytes is undefined in Python 2 and unicode is undefined in Python 3.

There are some ugly workarounds. An extremely ugly one is to compare the name of the type, instead of comparing the type itself. Here's an example:

# convert bytes (python 3) or unicode (python 2) to str
if str(type(s)) == "<class 'bytes'>":
    # only possible in Python 3
    s = s.decode('ascii')  # or  s = str(s)[2:-1]
elif str(type(s)) == "<type 'unicode'>":
    # only possible in Python 2
    s = str(s)

An arguably slightly less ugly workaround is to check the Python version number, e.g.:

if sys.version_info >= (3,0,0):
    # for Python 3
    if isinstance(s, bytes):
        s = s.decode('ascii')  # or  s = str(s)[2:-1]
else:
    # for Python 2
    if isinstance(s, unicode):
        s = str(s)

Those are both unpythonic, and most of the time there's probably a better way.

See my comment above asking for clarification on what you really want. Hopefully this is it:

System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.Diagnostics.FileVersionInfo fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);
string version = fvi.FileVersion;

What size this image should be depends on where it is to be used.

It is up to applications, eg WhatsApp, Facebook Messenger, Reddit, etc etc to decide what to do with the image. Some use it as a square image, some as a 1:19.1 rectangle, and some use different sizes when the display environment is of different sizes even for the same application. There are no rules, and there is no way to control what applications do with the image.

So you should test out the image on your intended target application(s) and find a compromise. That applications tend to cache the image makes it a pain on the trial and error approach.

Objects, which are also called instances, are self-contained elements of a program with related features and data. For the most part, you use the class merely to create instances and then work with those instances.

-Definition taken from the book "Sams Teach Yourself Java in 21 days".

Say you have 2 Classes, public class MainClass and public class Class_2 and you want to make an instance of Class_2 in MainClass.

This is a very simple and basic way to do it:

public MainClass()      /*******this is the constructor of MainClass*******/

{

 Class_2 nameyouwant = new Class_2();

}

I hope this helps!

This may do the trick:

\b\p{L}*Id\b

Where \p{L} matches any (Unicode) letter and \b matches a word boundary.

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

I also met the case to use both python2 and python3 on my Windows machine. Here's how i resolved it:

1. download python2x and python3x, installed them.
2. add C:\Python35;C:\Python35\Scripts;C:\Python27;C:\Python27\Scripts to environment variable PATH.
3. Go to C:\Python35 to rename python.exe to python3.exe, also to C:\Python27, rename python.exe to python2.exe.
4. restart your command window.
5. type python2 scriptname.py, or python3 scriptname.py in command line to switch the version you like.

You can use something like this:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


public class testHashes {

public static void main(String args[]){
    Map<String,String> myMap1 = new HashMap<String, String>();

    List<Map<String , String>> myMap  = new ArrayList<Map<String,String>>();

    myMap1.put("URL", "Val0");
    myMap1.put("CRC", "Vla1");
    myMap1.put("SIZE", "Val2");
    myMap1.put("PROGRESS", "Val3");

    myMap.add(0,myMap1);
    myMap.add(1,myMap1);

    for (Map<String, String> map : myMap) {
        System.out.println(map.get("URL"));
        System.out.println(map.get("CRC"));
        System.out.println(map.get("SIZE"));
        System.out.println(map.get("PROGRESS"));
    }

    //System.out.println(myMap);

}


}

Example: to view the Windows User Name on Cell C5, you can use this script :

Range("C5").Value = ": " & Environ("USERNAME").

Unlike a list or a dictionary, a generator can be infinite. Doing this wouldn't work:

def gen():
    x = 0
    while True:
        yield x
        x += 1
g1 = gen()
list(g1)   # never ends

Also, reading a generator changes it, so there's not a perfect way to view it. To see a sample of the generator's output, you could do

g1 = gen()
[g1.next() for i in range(10)]

Even after this my code is working fine , so i just removed all warning messages with this statement at line 1 .

<?php error_reporting(E_ERROR); ?>

>>> s = pd.Series([1,2,3,4,np.NaN,5,np.NaN])
>>> s[~s.isnull()]
0    1
1    2
2    3
3    4
5    5

update or even better approach as @DSM suggested in comments, using pandas.Series.dropna():

>>> s.dropna()
0    1
1    2
2    3
3    4
5    5

scrollIntoView works well:

document.getElementById("divFirst").scrollIntoView();

full reference in the MDN docs:
https://developer.mozilla.org/en-US/docs/Web/API/Element.scrollIntoView

The Array and List<T> classes already have ForEach methods, though only this specific implementation. (Note that the former is static, by the way).

Not sure it really offers a great advantage over a foreach statement, but you could write an extension method to do the job for all IEnumerable<T> objects.

public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)
{
    foreach (var item in source)
        action(item);
}

This would allow the exact code you posted in your question to work just as you want.

This seems considerably easier than what anyone else has suggested

select sysdate-to_date('30-jul-1977') from dual; 

foreach($equipxml as $equip) {
    $current_device = $equip->xpath("name");
    if ( $current_device[0] == $device ) {
        // found a match in the file            
        $nodeid = $equip->id;
        break;
    }
}

Simply use break. That will do it.

You can create a Date object, and call getTime on it:

new Date(2010, 6, 26).getTime() / 1000

Using OKIO

public static String readJsonFromAssets(Context context, String filePath) {
    
        try {
            InputStream input = context.getAssets().open(filePath);
            BufferedSource source = Okio.buffer(Okio.source(input));
            return source.readByteString().string(Charset.forName("utf-8"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    
        return null;
}

and then...

String data = readJsonFromAssets(context, "json/some.json"); //here is my file inside the folder assets/json/some.json

Type reviewType = new TypeToken<List<Object>>() {}.getType();

if (data != null) {
    Object object = new Gson().fromJson(data, reviewType);
}

Guess you just missed the find method in the docs:

my_array.find {|e| e.satisfies_condition? }

if you have added a new line, Make sure you have added next line syntax in previous line. typically if "\" is missing in your previous line of changes, you will get this error.

Try a list comprehension:

l = [x * 2 for x in l]

This goes through l, multiplying each element by two.

Of course, there's more than one way to do it. If you're into lambda functions and map, you can even do

l = map(lambda x: x * 2, l)

to apply the function lambda x: x * 2 to each element in l. This is equivalent to:

def timesTwo(x):
    return x * 2

l = map(timesTwo, l)

Note that map() returns a map object, not a list, so if you really need a list afterwards you can use the list() function afterwards, for instance:

l = list(map(timesTwo, l))

Thanks to Minyc510 in the comments for this clarification.

Maybe it sounds stupid but it worked for me when I had the same problem: delete the created avd and create one again through AVD Manager with a sd card of, for example, 512MB.

Check that both have the correct permissions and if not, try to change them with chmod.

And if everything still fails, repeat the process but creating both avd and sd card manually via terminal:

android create avd -n my_avd -t 7
mksdcard -l e 512M mysdcard.img
emulator -avd my_avd -sdcard mysdcard.img

Hope that helps!

If you try to decrypt PKCS5-padded data with the wrong key, and then unpad it (which is done by the Cipher class automatically), you most likely will get the BadPaddingException (with probably of slightly less than 255/256, around 99.61%), because the padding has a special structure which is validated during unpad and very few keys would produce a valid padding.

So, if you get this exception, catch it and treat it as "wrong key".

This also can happen when you provide a wrong password, which then is used to get the key from a keystore, or which is converted into a key using a key generation function.

Of course, bad padding can also happen if your data is corrupted in transport.

That said, there are some security remarks about your scheme:

• For password-based encryption, you should use a SecretKeyFactory and PBEKeySpec instead of using a SecureRandom with KeyGenerator. The reason is that the SecureRandom could be a different algorithm on each Java implementation, giving you a different key. The SecretKeyFactory does the key derivation in a defined manner (and a manner which is deemed secure, if you select the right algorithm).

• Don't use ECB-mode. It encrypts each block independently, which means that identical plain text blocks also give always identical ciphertext blocks.

  Preferably use a secure mode of operation, like CBC (Cipher block chaining) or CTR (Counter). Alternatively, use a mode which also includes authentication, like GCM (Galois-Counter mode) or CCM (Counter with CBC-MAC), see next point.

• You normally don't want only confidentiality, but also authentication, which makes sure the message is not tampered with. (This also prevents chosen-ciphertext attacks on your cipher, i.e. helps for confidentiality.) So, add a MAC (message authentication code) to your message, or use a cipher mode which includes authentication (see previous point).

• DES has an effective key size of only 56 bits. This key space is quite small, it can be brute-forced in some hours by a dedicated attacker. If you generate your key by a password, this will get even faster. Also, DES has a block size of only 64 bits, which adds some more weaknesses in chaining modes. Use a modern algorithm like AES instead, which has a block size of 128 bits, and a key size of 128 bits (for the standard variant).

Add:

• DELIMITER at the beginning and end of the SP.
• DROP PROCEDURE IF EXISTS validar_egreso; at the beginning
• When calling the SP, use @variableName.

This works for me. (I modified some part of your script so ANYONE can run it with out having your tables).

DROP PROCEDURE IF EXISTS `validar_egreso`;

DELIMITER $$

CREATE DEFINER='root'@'localhost' PROCEDURE `validar_egreso` (
    IN codigo_producto VARCHAR(100),
    IN cantidad INT,
    OUT valido INT(11)
)
BEGIN

    DECLARE resta INT;
    SET resta = 0;

    SELECT (codigo_producto - cantidad) INTO resta;

    IF(resta > 1) THEN
       SET valido = 1;
    ELSE
       SET valido = -1;
    END IF;

    SELECT valido;
END $$

DELIMITER ;

-- execute the stored procedure
CALL validar_egreso(4, 1, @val);

-- display the result
select @val;

You can just do:

@some_var.class == Hash

or also something like:

@some_var.is_a?(Hash)

It's worth noting that the "is_a?" method is true if the class is anywhere in the objects ancestry tree. for instance:

@some_var.is_a?(Object)  # => true

the above is true if @some_var is an instance of a hash or other class that stems from Object. So, if you want a strict match on the class type, using the == or instance_of? method is probably what you're looking for.

More than one line can be drawn on the same chart by using the lines()function

# Create the data for the chart.
v <- c(7,12,28,3,41)
t <- c(14,7,6,19,3)

# Give the chart file a name.
png(file = "line_chart_2_lines.jpg")

# Plot the bar chart.
plot(v,type = "o",col = "red", xlab = "Month", ylab = "Rain fall", 
   main = "Rain fall chart")

lines(t, type = "o", col = "blue")

# Save the file.
dev.off()

OUTPUT

For those using Select2 4.x, you can disable an individual option by doing:

$('select option:selected').prop('disabled', true);

For those using Select2 4.x, you can disable the entire dropdown with:

$('select').prop('disabled', true);

for those having problems after adding active and focus give a class or id name to your button and add this to css

for example

//html code

<button id="aboutus">ABOUT US</button>

//css code

#aboutus{background-color: white;border:none;outline-style: none;}

Java 8 solution for produce string like "key1: value1,key2: value2"

private static String hashMapToString(HashMap<String, String> hashMap) {

    return hashMap.keySet().stream()
            .map((key) -> key + ": " + hashMap.get(key))
            .collect(Collectors.joining(","));

}

and produce a list simple collect as list

private static List<String> hashMapToList(HashMap<String, String> hashMap) {

    return hashMap.keySet().stream()
            .map((key) -> key + ": " + hashMap.get(key))
            .collect(Collectors.toList());

}

and(re.search("bla_bla_pattern", str_item, re.IGNORECASE) == None)

is working.

A hash_map is an older, unstandardized version of what for standardization purposes is called an unordered_map (originally in TR1, and included in the standard since C++11). As the name implies, it's different from std::map primarily in being unordered -- if, for example, you iterate through a map from begin() to end(), you get items in order by key¹, but if you iterate through an unordered_map from begin() to end(), you get items in a more or less arbitrary order.

An unordered_map is normally expected to have constant complexity. That is, an insertion, lookup, etc., typically takes essentially a fixed amount of time, regardless of how many items are in the table. An std::map has complexity that's logarithmic on the number of items being stored -- which means the time to insert or retrieve an item grows, but quite slowly, as the map grows larger. For example, if it takes 1 microsecond to lookup one of 1 million items, then you can expect it to take around 2 microseconds to lookup one of 2 million items, 3 microseconds for one of 4 million items, 4 microseconds for one of 8 million items, etc.

From a practical viewpoint, that's not really the whole story though. By nature, a simple hash table has a fixed size. Adapting it to the variable-size requirements for a general purpose container is somewhat non-trivial. As a result, operations that (potentially) grow the table (e.g., insertion) are potentially relatively slow (that is, most are fairly fast, but periodically one will be much slower). Lookups, which cannot change the size of the table, are generally much faster. As a result, most hash-based tables tend to be at their best when you do a lot of lookups compared to the number of insertions. For situations where you insert a lot of data, then iterate through the table once to retrieve results (e.g., counting the number of unique words in a file) chances are that an std::map will be just as fast, and quite possibly even faster (but, again, the computational complexity is different, so that can also depend on the number of unique words in the file).

^{1 Where the order is defined by the third template parameter when you create the map, std::less<T> by default.}

I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???

1. Add dependencies inside your build.gradle file:

   dependencies {
       compile 'com.android.support:design:23.1.1'
   }
   

2. Add TabLayout inside your layout

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:orientation="vertical">
   
       <android.support.v7.widget.Toolbar
           android:id="@+id/toolbar"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:background="?attr/colorPrimary"/>
   
       <android.support.design.widget.TabLayout
           android:id="@+id/tab_layout"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"/>
   
       <android.support.v4.view.ViewPager
           android:id="@+id/pager"
           android:layout_width="match_parent"
           android:layout_height="match_parent"/>
   
   </LinearLayout>
   

3. Setup your Activity like this:

   import android.os.Bundle;
   import android.support.design.widget.TabLayout;
   import android.support.v4.app.Fragment;
   import android.support.v4.app.FragmentManager;
   import android.support.v4.app.FragmentPagerAdapter;
   import android.support.v4.view.ViewPager;
   import android.support.v7.app.AppCompatActivity;
   import android.support.v7.widget.Toolbar;
   
   public class TabLayoutActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_pull_to_refresh);
   
           Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
           TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
           ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
   
           if (toolbar != null) {
               setSupportActionBar(toolbar);
           }
   
           viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
           tabLayout.setupWithViewPager(viewPager);
       }
   
       public class SectionPagerAdapter extends FragmentPagerAdapter {
   
           public SectionPagerAdapter(FragmentManager fm) {
               super(fm);
           }
   
           @Override
           public Fragment getItem(int position) {
               switch (position) {
                   case 0:
                       return new FirstTabFragment();
                   case 1:
                   default:
                       return new SecondTabFragment();
               }
           }
   
           @Override
           public int getCount() {
               return 2;
           }
   
           @Override
           public CharSequence getPageTitle(int position) {
               switch (position) {
                   case 0:
                       return "First Tab";
                   case 1:
                   default:
                       return "Second Tab";
               }
           }
       }
   
   }
   

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

This is how Apple does it for classes like NSString:

In the header file:

enum {
    PlayerStateOff,
    PlayerStatePlaying,
    PlayerStatePaused
};

typedef NSInteger PlayerState;

Refer to Coding Guidelines at http://developer.apple.com/

You can use JVM args

java -Duser.country=ES -Duser.language=es -Duser.variant=Traditional_WIN

vim -c 'execute "silent !echo " . &fileencoding | q' {filename}

aliased somewhere in my bash configuration as

alias vic="vim -c 'execute \"silent \!echo \" . &fileencoding | q'"

so I just type

vic {filename}

On my vanilla OSX Yosemite, it yields more precise results than "file -I":

$ file -I pdfs/udocument0.pdf
pdfs/udocument0.pdf: application/pdf; charset=binary
$ vic pdfs/udocument0.pdf
latin1
$
$ file -I pdfs/t0.pdf
pdfs/t0.pdf: application/pdf; charset=us-ascii
$ vic pdfs/t0.pdf
utf-8

jQuery ui 1.9 is going to take care of this for you. Heres a demo of the pre:

https://dl.dropbox.com/u/3872624/lab/touch/index.html

Just grab the jquery.mouse.ui.js out, stick it under the jQuery ui file you're loading, and that's all you should have to do! Works for sortable as well.

This code is working great for me, but if your getting errors, an updated version of jquery.mouse.ui.js can be found here:

Jquery-ui sortable doesn't work on touch devices based on Android or IOS

You can create a temp file, then rename it back to original file:

Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:\test\file.txt"
strTemp = "c:\test\temp.txt"
Set objFile = objFS.GetFile(strFile)
Set objOutFile = objFS.CreateTextFile(strTemp,True)
Set ts = objFile.OpenAsTextStream(1,-2)
Do Until ts.AtEndOfStream
    strLine = ts.ReadLine
    ' do something with strLine 
    objOutFile.Write(strLine)
Loop
objOutFile.Close
ts.Close
objFS.DeleteFile(strFile)
objFS.MoveFile strTemp,strFile 

Usage is almost the same using OpenTextFile:

Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:\test\file.txt"
strTemp = "c:\test\temp.txt"
Set objFile = objFS.OpenTextFile(strFile)
Set objOutFile = objFS.CreateTextFile(strTemp,True)    
Do Until objFile.AtEndOfStream
    strLine = objFile.ReadLine
    ' do something with strLine 
    objOutFile.Write(strLine & "kndfffffff")
Loop
objOutFile.Close
objFile.Close
objFS.DeleteFile(strFile)
objFS.MoveFile strTemp,strFile 

Not a definite answer but too much to fit in comments:

I hypothesize they gave you a cert that either has a wrong issuer (although their server could use a more specific alert code for that) or a wrong subject. We know the cert matches your privatekey -- because both curl and openssl client paired them without complaining about a mismatch; but we don't actually know it matches their desired CA(s) -- because your curl uses openssl and openssl SSL client does NOT enforce that a configured client cert matches certreq.CAs.

Do openssl x509 <clientcert.pem -noout -subject -issuer and the same on the cert from the test P12 that works. Do openssl s_client (or check the one you did) and look under Acceptable client certificate CA names; the name there or one of them should match (exactly!) the issuer(s) of your certs. If not, that's most likely your problem and you need to check with them you submitted your CSR to the correct place and in the correct way. Perhaps they have different regimes in different regions, or business lines, or test vs prod, or active vs pending, etc.

If the issuer of your cert does match desiredCAs, compare its subject to the working (test-P12) one: are they in similar format? are there any components in the working one not present in yours? If they allow it, try generating and submitting a new CSR with a subject name exactly the same as the test-P12 one, or as close as you can get, and see if that produces a cert that works better. (You don't have to generate a new key to do this, but if you choose to, keep track of which certs match which keys so you don't get them mixed up.) If that doesn't help look at the certificate extensions with openssl x509 <cert -noout -text for any difference(s) that might reasonably be related to subject authorization, like KeyUsage, ExtendedKeyUsage, maybe Policy, maybe Constraints, maybe even something nonstandard.

If all else fails, ask the server operator(s) what their logs say about the problem, or if you have access look at the logs yourself.

You can do this by using a content provider. Each data item used in the application remains private to the application. If an application want to share data accross applications, there is only technique to achieve this, using a content provider, which provides interface to access that private data.

string source;
// source gets initialized
string dest;
if (source.Length > 0)
{
    dest = source.Substring(0, source.Length - 1);
}

if you have zsh installed you can also update ~/.zprofile with

if [[ -z "$LC_ALL" ]]; then
  export LC_ALL='en_US.UTF-8'
fi

and check the output using the locale cmd as show above

? locale                                                                                                                                           
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

The default way to detach from an interactive container is Ctrl+P Ctrl+Q, but you can override it when running a new container or attaching to existing container using the --detach-keys flag.

If anyone is interested in a sortable list with a changing index per listitem (1st, 2nd, 3th etc...:

http://jsfiddle.net/aph0c1rL/1/

$(".sortable").sortable(
{
  handle:         '.handle'
, placeholder:    'sort-placeholder'
, forcePlaceholderSize: true

}
, change: function( e, ui )
  {
      var seq
      , startPos = ui.item.data( 'start-pos' )
      , $index
      , correction
      ;

      // if startPos < placeholder pos, we go from top to bottom
      // else startPos > placeholder pos, we go from bottom to top and we need to correct the index with +1
      //
      correction = startPos <= ui.placeholder.index() ? 0 : 1;

      ui.item.parent().find( 'li.prize').each( function( idx, el )

  var suffix = '';

  if ( number / 10 % 10 === 1 )
  {
    suffix = "th";
  }
  else if ( number > 0 )

    switch( number % 10 )
    {
      case 1:

Your markup can look like this:

<ul class="sortable ">

    <div>
        <span class="ordinal-position">1st</span>
         A header

Type-safety should not be confused with static / dynamic typing or strong / weak typing.

A type-safe language is one where the only operations that one can execute on data are the ones that are condoned by the data's type. That is, if your data is of type X and X doesn't support operation y, then the language will not allow you to to execute y(X).

This definition doesn't set rules on when this is checked. It can be at compile time (static typing) or at runtime (dynamic typing), typically through exceptions. It can be a bit of both: some statically typed languages allow you to cast data from one type to another, and the validity of casts must be checked at runtime (imagine that you're trying to cast an Object to a Consumer - the compiler has no way of knowing whether it's acceptable or not).

Type-safety does not necessarily mean strongly typed, either - some languages are notoriously weakly typed, but still arguably type safe. Take Javascript, for example: its type system is as weak as they come, but still strictly defined. It allows automatic casting of data (say, strings to ints), but within well defined rules. There is to my knowledge no case where a Javascript program will behave in an undefined fashion, and if you're clever enough (I'm not), you should be able to predict what will happen when reading Javascript code.

An example of a type-unsafe programming language is C: reading / writing an array value outside of the array's bounds has an undefined behaviour by specification. It's impossible to predict what will happen. C is a language that has a type system, but is not type safe.

At each point in these instructions, check to see if the problem is fixed. If so, great! Otherwise, continue.

1. Get to Services. (I was able to right click the Apache launch icon to get there.)
2. Scroll down to MySQL. Click to start. This will get rid of the #2002 error. Now you'll have a new error:

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

1. Edit the C:\wamp\apps\phpmyadmin3.5.1\config.inc.php file, changing $cfg['Servers'][$i]['extension'] = 'mysqli'; to instead be= 'mysql'
2. Open Services again and Stop MySQL
3. While in Services, Start wampmysqld

This is convoluted, I know, but that's what worked for me. Some posts may say you need a password in the config file, but you don't. Mine is still ""

Hope this helps.

While it is not possible (as others have illustrated), you could use an annotation to carry over the parameter name, and obtain that though reflection.

Not the cleanest solution, but it gets the job done. Some webservices actually do this to keep parameter names (ie: deploying WSs with glassfish).

If you need the exact functionality of the back button in your custom button, why not just call yourActivity.onBackPressed() that way if you override the functionality of the backbutton your custom button will behave the same.

You don't need an IoC container.

But if you're rigorously following a DI pattern, you'll find that having one will remove a ton of redundant, boring code.

That's often the best time to use a library/framework, anyway - when you understand what it's doing and could do it without the library.

Not sure if this answers this question. But I was looking for something else. Highly recommend see this 2 minute video. If you wanted to get into more details then see docs - Handling Parameters and this link

And then if you have something like blue ocean, the choices would look something like this:

You define and access your variables like this:

pipeline {
    agent any

    parameters {
    string(defaultValue: "TEST", description: 'What environment?', name: 'userFlag')
    choice(choices: ['TESTING', 'STAGING', 'PRODUCTION'], description: 'Select field for target environment', name: 'DEPLOY_ENV')
    }

    stages {
        stage("foo") {
            steps {
                echo "flag: ${params.userFlag}"
                echo "flag: ${params.DEPLOY_ENV}"
            }
        }
    }
}

Automated builds will pick up the default params. But if you do it manually then you get the option to choose.

And then assign values like this:

The way I am trying to do this in my question actually works!

# environment/development.rb

ENV['admin_password'] = "secret" 

I just had to restart the server. I thought running reload! in rails console would be enough but I also had to restart the web server.

I am picking my own answer because I feel this is a better place to put and set the ENV variables

str_replace(PHP_EOL, null, $str);

the simplest solution

I wanted a very quick way to convert my set to List and return it, so in one line I did

 return new ArrayList<Long>(mySetVariable);

The value of hjust and vjust are only defined between 0 and 1:

• 0 means left-justified
• 1 means right-justified

Source: ggplot2, Hadley Wickham, page 196

(Yes, I know that in most cases you can use it beyond this range, but don't expect it to behave in any specific way. This is outside spec.)

hjust controls horizontal justification and vjust controls vertical justification.

An example should make this clear:

td <- expand.grid(
    hjust=c(0, 0.5, 1),
    vjust=c(0, 0.5, 1),
    angle=c(0, 45, 90),
    text="text"
)

ggplot(td, aes(x=hjust, y=vjust)) + 
    geom_point() +
    geom_text(aes(label=text, angle=angle, hjust=hjust, vjust=vjust)) + 
    facet_grid(~angle) +
    scale_x_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2)) +
    scale_y_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2))

To understand what happens when you change the hjust in axis text, you need to understand that the horizontal alignment for axis text is defined in relation not to the x-axis, but to the entire plot (where this includes the y-axis text). (This is, in my view, unfortunate. It would be much more useful to have the alignment relative to the axis.)

DF <- data.frame(x=LETTERS[1:3],y=1:3)
p <- ggplot(DF, aes(x,y)) + geom_point() + 
    ylab("Very long label for y") +
    theme(axis.title.y=element_text(angle=0))


p1 <- p + theme(axis.title.x=element_text(hjust=0)) + xlab("X-axis at hjust=0")
p2 <- p + theme(axis.title.x=element_text(hjust=0.5)) + xlab("X-axis at hjust=0.5")
p3 <- p + theme(axis.title.x=element_text(hjust=1)) + xlab("X-axis at hjust=1")

library(ggExtra)
align.plots(p1, p2, p3)

To explore what happens with vjust aligment of axis labels:

DF <- data.frame(x=c("a\na","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p1 <- p + theme(axis.text.x=element_text(vjust=0, colour="red")) + 
        xlab("X-axis labels aligned with vjust=0")
p2 <- p + theme(axis.text.x=element_text(vjust=0.5, colour="red")) + 
        xlab("X-axis labels aligned with vjust=0.5")
p3 <- p + theme(axis.text.x=element_text(vjust=1, colour="red")) + 
        xlab("X-axis labels aligned with vjust=1")


library(ggExtra)
align.plots(p1, p2, p3)

This Code Is for Vertical Middle and Horizontal Center Align without specify fixed height:

.parent-class-name {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
.className {_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  left: 0;_x000D_
  right: 0;_x000D_
  margin: 0 auto;_x000D_
  transform: translateY(-50%);_x000D_
  -moz-transform: translateY(-50%);_x000D_
  -webkit-transform: translateY(-50%);_x000D_
}

Boxing is required, when we have a function that needs object as a parameter, but we have different value types that need to be passed, in that case we need to first convert value types to object data types before passing it to the function.

I don't think that is true, try this instead:

class Program
    {
        static void Main(string[] args)
        {
            int x = 4;
            test(x);
        }

        static void test(object o)
        {
            Console.WriteLine(o.ToString());
        }
    }

That runs just fine, I didn't use boxing/unboxing. (Unless the compiler does that behind the scenes?)

Well, the shortest way I know of, is following:

psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}

database_name: Which database should you insert your file data in.

file_path: Absolute path to the file through which you want to perform the importing.

host_name: The name of the host. For development purposes, it is mostly localhost.

Upon entering this command in console, you will be prompted to enter your password.

Do the right thing; do the thing right!

Clear to previous mark: Command + L

Clear to previous bookmark: Option + Command + L

Clear to start: Command + K

f'{float(f"{i:.1g}"):g}'
# Or with Python <3.6,
'{:g}'.format(float('{:.1g}'.format(i)))

This solution is different from all of the others because:

1. it exactly solves the OP question
2. it does not need any extra package
3. it does not need any user-defined auxiliary function or mathematical operation

For an arbitrary number n of significant figures, you can use:

print('{:g}'.format(float('{:.{p}g}'.format(i, p=n))))

Test:

a = [1234, 0.12, 0.012, 0.062, 6253, 1999, -3.14, 0., -48.01, 0.75]
b = ['{:g}'.format(float('{:.1g}'.format(i))) for i in a]
# b == ['1000', '0.1', '0.01', '0.06', '6000', '2000', '-3', '0', '-50', '0.8']

Note: with this solution, it is not possible to adapt the number of significant figures dynamically from the input because there is no standard way to distinguish numbers with different numbers of trailing zeros (3.14 == 3.1400). If you need to do so, then non-standard functions like the ones provided in the to-precision package are needed.

If you want to use 32-bit references, your heap is limited to 32 GB.

However, if you are willing to use 64-bit references, the size is likely to be limited by your OS, just as it is with 32-bit JVM. e.g. on Windows 32-bit this is 1.2 to 1.5 GB.

Note: you will want your JVM heap to fit into main memory, ideally inside one NUMA region. That's about 1 TB on the bigger machines. If your JVM spans NUMA regions the memory access and the GC in particular will take much longer. If your JVM heap start swapping it might take hours to GC, or even make your machine unusable as it thrashes the swap drive.

Note: You can access large direct memory and memory mapped sizes even if you use 32-bit references in your heap. i.e. use well above 32 GB.

Compressed oops in the Hotspot JVM

Compressed oops represent managed pointers (in many but not all places in the JVM) as 32-bit values which must be scaled by a factor of 8 and added to a 64-bit base address to find the object they refer to. This allows applications to address up to four billion objects (not bytes), or a heap size of up to about 32Gb. At the same time, data structure compactness is competitive with ILP32 mode.

If you'd like your script to install missing packages and continue, you could do something like this (on example of 'krbV' module in 'python-krbV' package):

import pip
import sys

for m, pkg in [('krbV', 'python-krbV')]:
    try:
        setattr(sys.modules[__name__], m, __import__(m))
    except ImportError:
        pip.main(['install', pkg])
        setattr(sys.modules[__name__], m, __import__(m))

Angular UI Bootstrap - Pagination Directive

Check out UI Bootstrap's pagination directive. I ended up using it rather than what is posted here as it has enough features for my current use and has a thorough test spec to accompany it.

View

<!-- table here -->

<pagination 
  ng-model="currentPage"
  total-items="todos.length"
  max-size="maxSize"  
  boundary-links="true">
</pagination>

<!-- items/page select here if you like -->

Controller

todos.controller("TodoController", function($scope) {
   $scope.filteredTodos = []
  ,$scope.currentPage = 1
  ,$scope.numPerPage = 10
  ,$scope.maxSize = 5;

  $scope.makeTodos = function() {
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
      $scope.todos.push({ text:"todo "+i, done:false});
    }
  };
  $scope.makeTodos(); 

  $scope.$watch("currentPage + numPerPage", function() {
    var begin = (($scope.currentPage - 1) * $scope.numPerPage)
    , end = begin + $scope.numPerPage;

    $scope.filteredTodos = $scope.todos.slice(begin, end);
  });
});

I have made a working plunker for reference.

Legacy Version:

View

<!-- table here -->

<div data-pagination="" data-num-pages="numPages()" 
  data-current-page="currentPage" data-max-size="maxSize"  
  data-boundary-links="true"></div>

<!-- items/page select here if you like -->

Controller

todos.controller("TodoController", function($scope) {
   $scope.filteredTodos = []
  ,$scope.currentPage = 1
  ,$scope.numPerPage = 10
  ,$scope.maxSize = 5;

  $scope.makeTodos = function() {
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
      $scope.todos.push({ text:"todo "+i, done:false});
    }
  };
  $scope.makeTodos(); 

  $scope.numPages = function () {
    return Math.ceil($scope.todos.length / $scope.numPerPage);
  };

  $scope.$watch("currentPage + numPerPage", function() {
    var begin = (($scope.currentPage - 1) * $scope.numPerPage)
    , end = begin + $scope.numPerPage;

    $scope.filteredTodos = $scope.todos.slice(begin, end);
  });
});

Try this, perhaps it works ;)

.factory('authInterceptor', function($location, $q, $window) {


return {
    request: function(config) {
      config.headers = config.headers || {};

      config.headers.Authorization = 'xxxx-xxxx';

      return config;
    }
  };
})

.config(function($httpProvider) {
  $httpProvider.interceptors.push('authInterceptor');
})

And make sure your back end works too, try this. I'm using RESTful CodeIgniter.

class App extends REST_Controller {
    var $authorization = null;

    public function __construct()
    {
        parent::__construct();
        header('Access-Control-Allow-Origin: *');
        header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method, Authorization");
        header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
        if ( "OPTIONS" === $_SERVER['REQUEST_METHOD'] ) {
            die();
        }

        if(!$this->input->get_request_header('Authorization')){
            $this->response(null, 400);    
        }

        $this->authorization = $this->input->get_request_header('Authorization');
    }

}

I was playing with this and came up with an alternative.

$ VAR=/home/me/mydir/file.c

$ DIR=`echo $VAR |xargs dirname`

$ echo $DIR
/home/me/mydir

The part I liked is it was easy to extend backup the tree:

$ DIR=`echo $VAR |xargs dirname |xargs dirname |xargs dirname`

$ echo $DIR
/home

Inheritance creates a strong relationship between a subclass and super class; subclass must be aware of super class'es implementation details. Creating the super class is much harder, when you have to think about how it can be extended. You have to document class invariants carefully, and state what other methods overridable methods use internally.

Inheritance is sometimes useful, if the hierarchy really represents a is-a-relationship. It relates to Open-Closed Principle, which states that classes should be closed for modification but open to extension. That way you can have polymorphism; to have a generic method that deals with super type and its methods, but via dynamic dispatch the method of subclass is invoked. This is flexible, and helps to create indirection, which is essential in software (to know less about implementation details).

Inheritance is easily overused, though, and creates additional complexity, with hard dependencies between classes. Also understanding what happens during execution of a program gets pretty hard due to layers and dynamic selection of method calls.

I would suggest using composing as the default. It is more modular, and gives the benefit of late binding (you can change the component dynamically). Also it's easier to test the things separately. And if you need to use a method from a class, you are not forced to be of certain form (Liskov Substitution Principle).

I've made an alternative to the other good answers on here that uses PowerShell, but mine also saves the list to a file. Will share it here in case anyone else needs wants something like that.

Warning: Code overwrites "longfilepath.txt" in the current working directory. I know it's unlikely you'd have one already, but just in case!

Purposely wanted it in a single line:

Out-File longfilepath.txt ; cmd /c "dir /b /s /a" | ForEach-Object { if ($_.length -gt 250) {$_ | Out-File -append longfilepath.txt}}

Detailed instructions:

1. Run PowerShell
2. Traverse to the directory you want to check for filepath lengths (C: works)
3. Copy and paste the code [Right click to paste in PowerShell, or Alt + Space > E > P]
4. Wait until it's done and then view the file: cat longfilepath.txt | sort

Explanation:

Out-File longfilepath.txt ; – Create (or overwrite) a blank file titled 'longfilepath.txt'. Semi-colon to separate commands.

cmd /c "dir /b /s /a" | – Run dir command on PowerShell, /a to show all files including hidden files. | to pipe.

ForEach-Object { if ($_.length -gt 250) {$_ | Out-File -append longfilepath.txt}} – For each line (denoted as $_), if the length is greater than 250, append that line to the file.

Fetch vs Pull

Git fetch just updates your repo data, but a git pull will basically perform a fetch and then merge the branch pulled

What is the difference between 'git pull' and 'git fetch'?

Merge vs Rebase

from Atlassian SourceTree Blog, Merge or Rebase:

Merging brings two lines of development together while preserving the ancestry of each commit history.

In contrast, rebasing unifies the lines of development by re-writing changes from the source branch so that they appear as children of the destination branch – effectively pretending that those commits were written on top of the destination branch all along.

Also, check out Learn Git Branching, which is a nice game that has just been posted to HackerNews (link to post) and teaches a lot of branching and merging tricks. I believe it will be very helpful in this matter.

It's not possible with ES3 as the properties have an internal DontEnum attribute which prevents us from enumerating these properties. ES5, on the other hand, provides property descriptors for controlling the enumeration capabilities of properties so user-defined and native properties can use the same interface and enjoy the same capabilities, which includes being able to see non-enumerable properties programmatically.

The getOwnPropertyNames function can be used to enumerate over all properties of the passed in object, including those that are non-enumerable. Then a simple typeof check can be employed to filter out non-functions. Unfortunately, Chrome is the only browser that it works on currently.

?function getAllMethods(object) {
    return Object.getOwnPropertyNames(object).filter(function(property) {
        return typeof object[property] == 'function';
    });
}

console.log(getAllMethods(Math));

logs ["cos", "pow", "log", "tan", "sqrt", "ceil", "asin", "abs", "max", "exp", "atan2", "random", "round", "floor", "acos", "atan", "min", "sin"] in no particular order.

If the project came with a Visual Studio project file, then that should already be configured to find the headers for you. If not, you'll have to add the include file directory to the project settings by right-clicking the project and selecting Properties, clicking on "C/C++", and adding the directory containing the include files to the "Additional Include Directories" edit box.

The focus only works if the window is focused.

Use ((JavascriptExecutor)webDriver).executeScript("window.focus();"); to be sure.

Sometimes when you change/update @NgModule in your project, projects get compiled but changes doesn't get reflect. So, restart once to get expected results if you not get it. ng serve

Depsite the year old topic, this one seems to have the most of the answers for this problem. Just ren into it. Tried everything, starting from "cleans", ending with total ".metadata" and another server setup, and nothing worked.

Than i remembered that a while ago i'w decided to clean up some of the "pom" warnings, and there were some suggestions on "apply to the project data". Then i started to browse the folder project, where i found the source of my headache - a file called ".tomcatplugin". After deleting it(it was the third hour of my attempts of resolving the problem) everything worked like a charm.

This is off the cuff, but isn't that what Grasshopper was for?

You can also use scipy.signal.welch to estimate the power spectral density using Welch’s method. Here is an comparison between np.fft.fft and scipy.signal.welch:

from scipy import signal
import numpy as np
import matplotlib.pyplot as plt

fs = 10e3
N = 1e5
amp = 2*np.sqrt(2)
freq = 1234.0
noise_power = 0.001 * fs / 2
time = np.arange(N) / fs
x = amp*np.sin(2*np.pi*freq*time)
x += np.random.normal(scale=np.sqrt(noise_power), size=time.shape)

# np.fft.fft
freqs = np.fft.fftfreq(time.size, 1/fs)
idx = np.argsort(freqs)
ps = np.abs(np.fft.fft(x))**2
plt.figure()
plt.plot(freqs[idx], ps[idx])
plt.title('Power spectrum (np.fft.fft)')

# signal.welch
f, Pxx_spec = signal.welch(x, fs, 'flattop', 1024, scaling='spectrum')
plt.figure()
plt.semilogy(f, np.sqrt(Pxx_spec))
plt.xlabel('frequency [Hz]')
plt.ylabel('Linear spectrum [V RMS]')
plt.title('Power spectrum (scipy.signal.welch)')
plt.show()

As docs say you have to call setTheme before any view output. It seems that super.onCreate() takes part in view processing.

So, to switch between themes dynamically you simply need to call setTheme before super.onCreate like this:

public void onCreate(Bundle savedInstanceState) {
    setTheme(android.R.style.Theme);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
}

If the user successful login into your Node app, I'm thinking that you are using Express, isn't ? Well you can redirect easy by using res.redirect. Like:

app.post('/auth', function(req, res) {
  // Your logic and then redirect
  res.redirect('/user_profile');
});

This error means that, while linking, compiler is not able to find the definition of main() function anywhere.

In your makefile, the main rule will expand to something like this.

main: producer.o consumer.o AddRemove.o
   gcc -pthread -Wall -o producer.o consumer.o AddRemove.o

As per the gcc manual page, the use of -o switch is as below

-o file     Place output in file file. This applies regardless to whatever sort of output is being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code. If -o is not specified, the default is to put an executable file in a.out.

It means, gcc will put the output in the filename provided immediate next to -o switch. So, here instead of linking all the .o files together and creating the binary [main, in your case], its creating the binary as producer.o, linking the other .o files. Please correct that.

I don't have Python 2.7 installed, but in Python 3.3 calling Popen with stdout set to sys.stdout worked just fine. Not before I had escaped the backslashes in the path, though.

>>> import sys
>>> p = subprocess.Popen(['powershell.exe', 'C:\\Temp\\test.ps1'], stdout=sys.stdout)
>>> Hello World

I am using git in eclipse and I was having the same problem.

Eventually I found that the "Rebase ..." menu entry was temporarily transformed into a sub-menu.

Team-> Rebase -> Abort

It worked for me.

I had a similar problem with a request to a non-SSL service.

This blog suggested vaguely to try URI encoding the URL that is passed to 'get': http://www.loudthinking.org/2010/02/ruby-eoferror-end-of-file-reached.html

I took a shot at it, based on desperation, and in my limiting testing this seems to have fixed it for me. My new code is:

@http = Net::HTTP.new('domain.com')  
@http = @http.start    
url = 'http://domain.com/requested_url?blah=blah&etc=1'
req = Net::HTTP::Get.new(URI.encode(url))
req.basic_auth USERNAME, API_KEY
res = @http.request(req) 

Note that I use @http.start as I want to maintain the HTTP session over multiple requests. Other than that, you might like to try the most relevant part which is: URI.encode(url) inside the get call

DISCLAIMER: this answer is from Jul 2015 and uses Retrofit and OkHttp from that time.
Check this link for more info on Retrofit v2 and this one for the current OkHttp methods.

Okay, I got it working using Android Developers guide.

Just as OP, I'm trying to use Retrofit and OkHttp to connect to a self-signed SSL-enabled server.

Here's the code that got things working (I've removed the try/catch blocks):

public static RestAdapter createAdapter(Context context) {
  // loading CAs from an InputStream
  CertificateFactory cf = CertificateFactory.getInstance("X.509");
  InputStream cert = context.getResources().openRawResource(R.raw.my_cert);
  Certificate ca;
  try {
    ca = cf.generateCertificate(cert);
  } finally { cert.close(); }

  // creating a KeyStore containing our trusted CAs
  String keyStoreType = KeyStore.getDefaultType();
  KeyStore keyStore = KeyStore.getInstance(keyStoreType);
  keyStore.load(null, null);
  keyStore.setCertificateEntry("ca", ca);

  // creating a TrustManager that trusts the CAs in our KeyStore
  String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
  TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
  tmf.init(keyStore);

  // creating an SSLSocketFactory that uses our TrustManager
  SSLContext sslContext = SSLContext.getInstance("TLS");
  sslContext.init(null, tmf.getTrustManagers(), null);

  // creating an OkHttpClient that uses our SSLSocketFactory
  OkHttpClient okHttpClient = new OkHttpClient();
  okHttpClient.setSslSocketFactory(sslContext.getSocketFactory());

  // creating a RestAdapter that uses this custom client
  return new RestAdapter.Builder()
              .setEndpoint(UrlRepository.API_BASE)
              .setClient(new OkClient(okHttpClient))
              .build();
}

To help in debugging, I also added .setLogLevel(RestAdapter.LogLevel.FULL) to my RestAdapter creation commands and I could see it connecting and getting the response from the server.

All it took was my original .crt file saved in main/res/raw. The .crt file, aka the certificate, is one of the two files created when you create a certificate using openssl. Generally, it is a .crt or .cert file, while the other is a .key file.

Afaik, the .crt file is your public key and the .key file is your private key.

As I can see, you already have a .cert file, which is the same, so try to use it.

PS: For those that read it in the future and only have a .pem file, according to this answer, you only need this to convert one to the other:

openssl x509 -outform der -in your-cert.pem -out your-cert.crt

PS²: For those that don't have any file at all, you can use the following command (bash) to extract the public key (aka certificate) from any server:

echo -n | openssl s_client -connect your.server.com:443 | \
  sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/my_cert.crt

Just replace the your.server.com and the port (if it is not standard HTTPS) and choose a valid path for your output file to be created.

Apply 100% width and height to your image:

<div style="height:42px;width:42px">
  <img src="http://someimage.jpg" style="width:100%; height:100%">
</div>

This way it will same size of its parent.

Both are valid but I normally choose interfaces. A class (abstract or not) is not needed if there is no implementations.

As an advise, try to choose the location of your constants wisely, they are part of your external contract. Do not put every single constant in one file.

For example, if a group of constants is only used in one class or one method put them in that class, the extended class or the implemented interfaces. If you do not take care you could end up with a big dependency mess.

Sometimes an enumeration is a good alternative to constants (Java 5), take look at: http://docs.oracle.com/javase/1.5.0/docs/guide/language/enums.html

CI Session Class track information about each user while they browse site.Ci Session class generates its own session data, offering more flexibility for developers.

Initializing a Session

To initialize the Session class manually in our controller constructor use following code.

Adding Custom Session Data

We can add our custom data in session array.To add our data to the session array involves passing an array containing your new data to this function.

$this->session->set_userdata($newarray);

Where $newarray is an associative array containing our new data.

$newarray = array( 'name' => 'manish', 'email' => '[email protected]'); $this->session->set_userdata($newarray); 

Retrieving Session

$session_id = $this->session->userdata('session_id');

Above function returns FALSE (boolean) if the session array does not exist.

Retrieving All Session Data

$this->session->all_userdata()

I have taken reference from http://www.tutsway.com/codeigniter-session.php.

I will add that one of the important things about shared_ptr's is to only ever construct them with the following syntax:

shared_ptr<Type>(new Type(...));

This way, the "real" pointer to Type is anonymous to your scope, and held only by the shared pointer. Thus it will be impossible for you to accidentally use this "real" pointer. In other words, never do this:

Type* t_ptr = new Type(...);
shared_ptr<Type> t_sptr ptrT(t_ptr);
//t_ptr is still hanging around!  Don't use it!

Although this will work, you now have a Type* pointer (t_ptr) in your function which lives outside the shared pointer. It's dangerous to use t_ptr anywhere, because you never know when the shared pointer which holds it may destruct it, and you'll segfault.

Same goes for pointers returned to you by other classes. If a class you didn't write hands you a pointer, it's generally not safe to just put it in a shared_ptr. Not unless you're sure that the class is no longer using that object. Because if you do put it in a shared_ptr, and it falls out of scope, the object will get freed when the class may still need it.

Here is a solution in Scala:

def subsets[T](s : Set[T]) : Set[Set[T]] = 
  if (s.size == 0) Set(Set()) else { 
    val tailSubsets = subsets(s.tail); 
    tailSubsets ++ tailSubsets.map(_ + s.head) 
} 

I never understood why this makes a difference for the compiler, but this is sufficient.

public static class ControlExtensions
{
    public static void Invoke(this Control control, Action action)
    {
        control.Invoke(action);
    }
}

Bonus: add some error handling, because it is likely that, if you are using Control.Invoke from a background thread you are updating the text / progress / enabled state of a control and don't care if the control is already disposed.

public static class ControlExtensions
{
    public static void Invoke(this Control control, Action action)
    {
        try
        {
            if (!control.IsDisposed) control.Invoke(action);
        }
        catch (ObjectDisposedException) { }
    }
}

The following is a complete Blade (the templating engine Laravel uses) solution:

{!! link_to(URL::previous(), 'Cancel', ['class' => 'btn btn-default']) !!}

The options array with the class is optional, in this case it specifies the styling for a Bootstrap 3 button.

Add**/.DS_Store into .gitignore for the sub directory

find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch

To ignore them in all repository: (sometimes it named ._.DS_Store)

echo ".DS_Store" >> ~/.gitignore_global
echo "._.DS_Store" >> ~/.gitignore_global
echo "**/.DS_Store" >> ~/.gitignore_global
echo "**/._.DS_Store" >> ~/.gitignore_global
git config --global core.excludesfile ~/.gitignore_global

Setup a watcher on the $route in your component like this:

watch:{
    $route (to, from){
        this.show = false;
    }
} 

This observes for route changes and when changed ,sets show to false

public static float roundFloat(float in) {
    return ((int)((in*100f)+0.5f))/100f;
}

Should be ok for most cases. You can still changes types if you want to be compliant with doubles for instance.

After the configure step you probably have a makefile. Inside this makefile look for CFLAGS (or similar). puf -fPIC at the end and run make again. In other words -fPIC is a compiler option that has to be passed to the compiler somewhere.

Here is a working example: http://jsfiddle.net/rVBzt/ (using jQuery)

<img id="tiger" src="https://twimg0-a.akamaihd.net/profile_images/2642324404/46d743534606515238a9a12cfb4b264a.jpeg">

<a id="toggle">click to toggle</a>

img {display: none;}

a {cursor: pointer; color: blue;}

$('#toggle').click(function() {
    $('#tiger').toggle();
});

This might be an old question, but here's what I did:

In a .conf file loaded by apache:

<VirtualHost *:80>
  ServerName something.com
  ProxyPass / http://localhost:8080/
</VirtualHost>

Explanation: Listen on all requests to the local machine's port 80. If I requested "http://something.com/somethingorother", forward that request to "http://localhost:8080/somethingorother". This should work for an external visitor because, according to the docs, it maps the remote request to the local server's space.

I'm running Apache 2.4.6-2ubuntu2.2, so I'm not sure how the "-2ubuntu2.2" affects the wider applicability of this answer.

After you make these changes, add the needed modules and restart apache

sudo a2enmod proxy && sudo a2enmod proxy_http && sudo service apache2 restart

Why not use this simple but powerful command?

git filter-branch --tree-filter 'rm -f DVD-rip' HEAD

The --tree-filter option runs the specified command after each checkout of the project and then recommits the results. In this case, you remove a file called DVD-rip from every snapshot, whether it exists or not.

If you know which commit introduced the huge file (say 35dsa2), you can replace HEAD with 35dsa2..HEAD to avoid rewriting too much history, thus avoiding diverging commits if you haven't pushed yet. This comment courtesy of @alpha_989 seems too important to leave out here.

See this link.

Try mkdir -p:

mkdir -p foo

Note that this will also create any intermediate directories that don't exist; for instance,

mkdir -p foo/bar/baz

will create directories foo, foo/bar, and foo/bar/baz if they don't exist.

Some implementation like GNU mkdir include mkdir --parents as a more readable alias, but this is not specified in POSIX/Single Unix Specification and not available on many common platforms like macOS, various BSDs, and various commercial Unixes, so it should be avoided.

If you want an error when parent directories don't exist, and want to create the directory if it doesn't exist, then you can test for the existence of the directory first:

[ -d foo ] || mkdir foo

use:

var parsedobj = jQuery.parseJSON( jsonObj);

This will only be useful if you don't need the format to stay in string. otherwise you'd have to convert this back to JSON using the JSON library.

In my case, this error was caused by an identical server instance already running background.

The weird thing is when I started my server without notice there's one running already, the console didn't show anything like 'something is using port xxx'. I could even upload something to the server. So, it took me quite long to locate this problem.

What's more, after closing all the applications I can imagine, I still could not find the process which is using this port in my Mac's activity monitor. I have to use lsof to trace. The culprit was not surprising - it's a node process. However, with the PID shown in the terminal, I found the port number in the monitor is different from the one used by my server.

All in all, kill all the node processes may solve this problem directly.

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

DECLARE
   tmp NUMBER(3,1);
BEGIN
  SELECT COUNT(content_id) INTO tmp FROM contents WHERE (condition);
  if tmp != 0 then
    INSERT INTO contents VALUES (...);
  else
    INSERT INTO contents VALUES (...);
  end if;
END;

I used the code above. It is long, but, simple and worked for me. Similar, to Micheal's code.

I was also getting same issue as i tried using value 0 in non-based indexing,i.e starting with 1, not with zero

After fetching a zillion times still added remotes didn't show up, although the blobs were in the pool. Turns out the --tags option shouldn't be given to git remote add for whatever reason. You can manually remove it from the .git/config to make git fetch create the refs.

var TableRowItem = React.createClass({
  render: function() {

    var td = function() {
        return this.props.columns.map(function(c, i) {
          return <td key={i}>{this.props.data[c]}</td>;
        }, this);
      }.bind(this);

    return (
      <tr>{ td(this.props.item) }</tr>
    )
  }
});

This will sove the problem.

You can use

if("/quit".equals(s))
   ...

or

if("/quit".compareTo(s) == 0) 
    ...

The latter makes a lexicographic comparison, and will return 0 if the two strings are the same.

pyspark.sql.functions.split() is the right approach here - you simply need to flatten the nested ArrayType column into multiple top-level columns. In this case, where each array only contains 2 items, it's very easy. You simply use Column.getItem() to retrieve each part of the array as a column itself:

split_col = pyspark.sql.functions.split(df['my_str_col'], '-')
df = df.withColumn('NAME1', split_col.getItem(0))
df = df.withColumn('NAME2', split_col.getItem(1))

The result will be:

col1 | my_str_col | NAME1 | NAME2
-----+------------+-------+------
  18 |  856-yygrm |   856 | yygrm
 201 |  777-psgdg |   777 | psgdg

I am not sure how I would solve this in a general case where the nested arrays were not the same size from Row to Row.

You can also just use the @{ } block to create functions:

@{
    async Task<string> MyAsyncString(string input)
    {
        return Task.FromResult(input);
    }
}

Then later in your razor page:

   <div>@(await MyAsyncString("weee").ConfigureAwait(false))</div>

I use this quite often in hard realtime systems that have fairly insane update rates (50kilosamples/sec) As a result I typically precompute the scalars.

To compute a moving average of N samples: scalar1 = 1/N; scalar2 = 1 - scalar1; // or (1 - 1/N) then:

Average = currentSample*scalar1 + Average*scalar2;

Example: Sliding average of 10 elements

double scalar1 = 1.0/10.0;  // 0.1
double scalar2 = 1.0 - scalar1; // 0.9
bool first_sample = true;
double average=0.0;
while(someCondition)
{
   double newSample = getSample();
   if(first_sample)
   {
    // everybody forgets the initial condition *sigh*
      average = newSample;
      first_sample = false;
   }
   else
   {
      average = (sample*scalar1) + (average*scalar2);
   }
 }

Note: this is just a practical implementation of the answer given by steveha above. Sometimes it's easier to understand a concrete example.
