Also, you may want to check out this podcast on scripting languages.

bash does not abort the running execution in case something detects an error state (unless you set the -e flag). Programming languages which offer try/catch do this in order to inhibit a "bailing out" because of this special situation (hence typically called "exception").

In the bash, instead, only the command in question will exit with an exit code greater than 0, indicating that error state. You can check for that of course, but since there is no automatic bailing out of anything, a try/catch does not make sense. It is just lacking that context.

You can, however, simulate a bailing out by using sub shells which can terminate at a point you decide:

(
  echo "Do one thing"
  echo "Do another thing"
  if some_condition
  then
    exit 3  # <-- this is our simulated bailing out
  fi
  echo "Do yet another thing"
  echo "And do a last thing"
)   # <-- here we arrive after the simulated bailing out, and $? will be 3 (exit code)
if [ $? = 3 ]
then
  echo "Bail out detected"
fi

Instead of that some_condition with an if you also can just try a command, and in case it fails (has an exit code greater than 0), bail out:

(
  echo "Do one thing"
  echo "Do another thing"
  some_command || exit 3
  echo "Do yet another thing"
  echo "And do a last thing"
)
...

Unfortunately, using this technique you are restricted to 255 different exit codes (1..255) and no decent exception objects can be used.

If you need more information to pass along with your simulated exception, you can use the stdout of the subshells, but that is a bit complicated and maybe another question ;-)

Using the above mentioned -e flag to the shell you can even strip that explicit exit statement:

(
  set -e
  echo "Do one thing"
  echo "Do another thing"
  some_command
  echo "Do yet another thing"
  echo "And do a last thing"
)
...

With multiple joins, use something like this code:

$someId = 44;
Event::with(["owner", "participants" => function($q) use($someId){
    $q->where('participants.IdUser', '=', 1);
    //$q->where('some other field', $someId);
}])

I have a similar problem with references not being recognized in VS2010 and the answers herein were not able to correct it.

The problem in my solution was related to the extension of the path where the project referenced was located. As I am working with SVN, I made a branch of a repository to do some testing and that branch increased two levels in path structure, so the path became too long to be usable in windows. This did not throw any error but did not recognize the namespace of the project reference. When I correct the location of the project to have a smaller path everything went fine.

Another option

echo foo >>/dev/stderr

The reason you separate the login and non-login shell is because the .bashrc file is reloaded every time you start a new copy of Bash. The .profile file is loaded only when you either log in or use the appropriate flag to tell Bash to act as a login shell.

Personally,

• I put my PATH setup into a .profile file (because I sometimes use other shells);
• I put my Bash aliases and functions into my .bashrc file;

• I put this

  #!/bin/bash
  #
  # CRM .bash_profile Time-stamp: "2008-12-07 19:42"
  #
  # echo "Loading ${HOME}/.bash_profile"
  source ~/.profile # get my PATH setup
  source ~/.bashrc  # get my Bash aliases
  

  in my .bash_profile file.

Oh, and the reason you need to type bash again to get the new alias is that Bash loads your .bashrc file when it starts but it doesn't reload it unless you tell it to. You can reload the .bashrc file (and not need a second shell) by typing

source ~/.bashrc

which loads the .bashrc file as if you had typed the commands directly to Bash.

In phpMyAdmin, click the table, and then click the Import tab at the top of the page.

Browse and open the csv file. Leave the charset as-is. Uncheck partial import unless you have a HUGE dataset (or slow server). The format should already have selected “CSV” after selecting your file, if not then select it (not using LOAD DATA). If you want to clear the whole table before importing, check “Replace table data with file”. Optionally check “Ignore duplicate rows” if you think you have duplicates in the CSV file. Now the important part, set the next four fields to these values:

Fields terminated by: ,
Fields enclosed by: “
Fields escaped by: \
Lines terminated by: auto

Currently these match the defaults except for “Fields terminated by”, which defaults to a semicolon.

Now click the Go button, and it should run successfully.

Regarding your second question, generally you don't need to use pointers while programming, however there is one exception to this and that is when you make a public API.

The problem with C++ constructs that people generally use to replace pointers are very dependent on the toolset that you use which is fine when you have all the control you need over the source code, however if you compile a static library with visual studio 2008 for instance and try to use it in a visual studio 2010 you will get a ton of linker errors because the new project is linked with a newer version of STL which is not backwards compatible. Things get even nastier if you compile a DLL and give an import library that people use in a different toolset because in that case your program will crash sooner or later for no apparent reason.

So for the purpose of moving large data sets from one library to another you could consider giving a pointer to an array to the function that is supposed to copy the data if you don't want to force others to use the same tools that you use. The good part about this is that it doesn't even have to be a C-style array, you can use a std::vector and give the pointer by giving the address of the first element &vector[0] for instance, and use the std::vector to manage the array internally.

Another good reason to use pointers in C++ again relates to libraries, consider having a dll that cannot be loaded when your program runs, so if you use an import library then the dependency isn't satisfied and the program crashes. This is the case for instance when you give a public api in a dll alongside your application and you want to access it from other applications. In this case in order to use the API you need to load the dll from its' location (usually it's in a registry key) and then you need to use a function pointer to be able to call functions inside the DLL. Sometimes the people that make the API are nice enough to give you a .h file that contain helper functions to automate this process and give you all the function pointers that you need, but if not you can use LoadLibrary and GetProcAddress on windows and dlopen and dlsym on unix to get them (considering that you know the entire signature of the function).

CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(
    Convert.ToInt32(e.Row.Cells[7].Text.Substring(3,2))).Substring(0,3) 
    + "-" 
    + Convert.ToDateTime(e.Row.Cells[7].Text).ToString("yyyy");

A const (being determined at compile-time) can be used in cases where a readonly static can't, like in switch statements, or attribute constructors. This is because readonly fields are only resolved at run-time, and some code constructs require compile time assurance. A readonly static can be calculated in a constructor, which is often an essential and useful thing. The difference is functional, as should be their usage in my opinion.

In terms of memory allocation, at least with strings (being a reference type), there seems to be no difference in that both are interned and will reference the one interned instance.

Personally, my default is readonly static, as it makes more semantic and logical sense to me, especially since most values are not needed at compile time. And, by the way, public readonly statics are not unusual or uncommon at all as the marked answer states: for instance, System.String.Empty is one.

Although I agree completely with delnan's answer, it's not impossible:

loop = range(NUM_ITERATIONS+1)
while loop.pop():
    do_stuff()

Note, however, that this will not work for an arbitrary list: If the first value in the list (the last one popped) does not evaluate to False, you will get another iteration and an exception on the next pass: IndexError: pop from empty list. Also, your list (loop) will be empty after the loop.

Just for curiosity's sake. ;)

Without specifying the path you can do:

constructor(private route: ActivatedRoute, private router: Router) { }

reload() {
  this.router.routeReuseStrategy.shouldReuseRoute = () => false;
  this.router.onSameUrlNavigation = 'reload';
  this.router.navigate(['./'], { relativeTo: this.route });
}

And if you use query params you can do:

reload() {
  ...
  this.router.navigate(['./'], { relativeTo: this.route, queryParamsHandling: 'preserve' });
}

You can do this via

• a. Manually: copy of all the Javascript files into one, run a compressor on it (optional but recommended) and upload to the server and link to that file.
• b. Use PHP: Just create an array of all JS files and include them all and output into a <script> tag

You can have any length, but of course, there can be a memory issue on the computer if the String input is too long. The output is always 32 characters.

The browser is trying to convert chucknorris into hex colour code, because it’s not a valid value.

1. In chucknorris, everything except c is not a valid hex value.
2. So it gets converted to c00c00000000.
3. Which becomes #c00000, a shade of red.

This seems to be an issue primarily with Internet Explorer and Opera (12) as both Chrome (31) and Firefox (26) just ignore this.

P.S. The numbers in brackets are the browser versions I tested on.

On a lighter note

Chuck Norris doesn’t conform to web standards. Web standards conform to him. #BADA55

If you are using custom adapters than android:focusable="false" and android:focusableInTouchMode="false" are nessesury to make list items clickable while using checkbox.

<CheckBox
        android:id="@+id/checkbox_fav"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/checkbox_layout"/>

In drawable>checkbox_layout.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/uncked_checkbox"
        android:state_checked="false"/>
    <item android:drawable="@drawable/selected_checkbox"
        android:state_checked="true"/>
    <item android:drawable="@drawable/uncked_checkbox"/>
</selector>

You have used '/0' instead of '\0'. This is incorrect: the '\0' is a null character, while '/0' is a multicharacter literal.

Moreover, in C it is OK to skip a zero in your condition:

while (*(forward++)) {
    ...
}

is a valid way to check character, integer, pointer, etc. for being zero.

If you want to cut out the last or the first do this:

list = ["This", "is", "a", "list"]
listnolast = list[:-1]
listnofirst = list[1:]

If you change 1 to 2 the first 2 characters will be removed not the second. Hope this still helps!

The below code will give you list of all the rows:-

df[df['C'] != 'XYZ']

To store the values from the above code into a dataframe :-

newdf = df[df['C'] != 'XYZ']

There's a simple way to this in any C-like language. The style is not Pythonic but works with pure Python:

def remove_html_markup(s):
    tag = False
    quote = False
    out = ""

    for c in s:
            if c == '<' and not quote:
                tag = True
            elif c == '>' and not quote:
                tag = False
            elif (c == '"' or c == "'") and tag:
                quote = not quote
            elif not tag:
                out = out + c

    return out

The idea based in a simple finite-state machine and is detailed explained here: http://youtu.be/2tu9LTDujbw

You can see it working here: http://youtu.be/HPkNPcYed9M?t=35s

In case you'd like to paste windows path from other source (say, File Explorer) - you can do so via input() call in python console:

>>> input()
D:\EP\stuff\1111\this_is_a_long_path\you_dont_want\to_type\or_edit_by_hand
'D:\\EP\\stuff\\1111\\this_is_a_long_path\\you_dont_want\\to_type\\or_edit_by_hand'

Then just copy the result

I noticed that this question was not marked as answered after 2 years - I think the closest answer is Richards, but it can be simplified quite a lot to this:

list1.Concat(list2)
    .ToLookup(p => p.Name)
    .Select(g => g.Aggregate((p1, p2) => new Person 
    {
        Name = p1.Name,
        Value = p1.Value, 
        Change = p2.Value - p1.Value 
    }));

Although this won't error in the case where you have duplicate names in either set.

Some other answers have suggested using unioning - this is definitely not the way to go as it will only get you a distinct list, without doing the combining.

If its working when you are using a browser and then passing on your username and password for the first time - then this means that once authentication is done Request header of your browser is set with required authentication values, which is then passed on each time a request is made to hosting server.

So start with inspecting Request Header (this could be done using Web Developers tools), Once you established whats required in header then you could pass this within your HttpWebRequest Header.

Example with Digest Authentication:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
using System.Text.RegularExpressions;
using System.Net;
using System.IO;

namespace NUI
{
    public class DigestAuthFixer
    {
        private static string _host;
        private static string _user;
        private static string _password;
        private static string _realm;
        private static string _nonce;
        private static string _qop;
        private static string _cnonce;
        private static DateTime _cnonceDate;
        private static int _nc;

public DigestAuthFixer(string host, string user, string password)
{
    // TODO: Complete member initialization
    _host = host;
    _user = user;
    _password = password;
}

private string CalculateMd5Hash(
    string input)
{
    var inputBytes = Encoding.ASCII.GetBytes(input);
    var hash = MD5.Create().ComputeHash(inputBytes);
    var sb = new StringBuilder();
    foreach (var b in hash)
        sb.Append(b.ToString("x2"));
    return sb.ToString();
}

private string GrabHeaderVar(
    string varName,
    string header)
{
    var regHeader = new Regex(string.Format(@"{0}=""([^""]*)""", varName));
    var matchHeader = regHeader.Match(header);
    if (matchHeader.Success)
        return matchHeader.Groups[1].Value;
    throw new ApplicationException(string.Format("Header {0} not found", varName));
}

private string GetDigestHeader(
    string dir)
{
    _nc = _nc + 1;

    var ha1 = CalculateMd5Hash(string.Format("{0}:{1}:{2}", _user, _realm, _password));
    var ha2 = CalculateMd5Hash(string.Format("{0}:{1}", "GET", dir));
    var digestResponse =
        CalculateMd5Hash(string.Format("{0}:{1}:{2:00000000}:{3}:{4}:{5}", ha1, _nonce, _nc, _cnonce, _qop, ha2));

    return string.Format("Digest username=\"{0}\", realm=\"{1}\", nonce=\"{2}\", uri=\"{3}\", " +
        "algorithm=MD5, response=\"{4}\", qop={5}, nc={6:00000000}, cnonce=\"{7}\"",
        _user, _realm, _nonce, dir, digestResponse, _qop, _nc, _cnonce);
}

public string GrabResponse(
    string dir)
{
    var url = _host + dir;
    var uri = new Uri(url);

    var request = (HttpWebRequest)WebRequest.Create(uri);

    // If we've got a recent Auth header, re-use it!
    if (!string.IsNullOrEmpty(_cnonce) &&
        DateTime.Now.Subtract(_cnonceDate).TotalHours < 1.0)
    {
        request.Headers.Add("Authorization", GetDigestHeader(dir));
    }

    HttpWebResponse response;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (WebException ex)
    {
        // Try to fix a 401 exception by adding a Authorization header
        if (ex.Response == null || ((HttpWebResponse)ex.Response).StatusCode != HttpStatusCode.Unauthorized)
            throw;

        var wwwAuthenticateHeader = ex.Response.Headers["WWW-Authenticate"];
        _realm = GrabHeaderVar("realm", wwwAuthenticateHeader);
        _nonce = GrabHeaderVar("nonce", wwwAuthenticateHeader);
        _qop = GrabHeaderVar("qop", wwwAuthenticateHeader);

        _nc = 0;
        _cnonce = new Random().Next(123400, 9999999).ToString();
        _cnonceDate = DateTime.Now;

        var request2 = (HttpWebRequest)WebRequest.Create(uri);
        request2.Headers.Add("Authorization", GetDigestHeader(dir));
        response = (HttpWebResponse)request2.GetResponse();
    }
    var reader = new StreamReader(response.GetResponseStream());
    return reader.ReadToEnd();
}

}

Then you could call it:

DigestAuthFixer digest = new DigestAuthFixer(domain, username, password);
string strReturn = digest.GrabResponse(dir);

if Url is: http://xyz.rss.com/folder/rss then domain: http://xyz.rss.com (domain part) dir: /folder/rss (rest of the url)

you could also return it as stream and use XmlDocument Load() method.

git show <revhash>

Documentation here. Or if that doesn't work, try Google Code's GIT Documentation

If it's your root module just add it to PYTHONPATH (PyCharm usually does that)

export PYTHONPATH=$PYTHONPATH:<root module path>

for Docker:

ENV PYTHONPATH="${PYTHONPATH}:<root module path in container>"

I've used this:

RewriteEngine On

# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ http://example.com/folder/$1 [R=301,L]

# Redirect external .php requests to extensionless URL
RewriteCond %{THE_REQUEST} ^(.+)\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(.+)\.php$ http://example.com/folder/$1 [R=301,L]

# Resolve .php file for extensionless PHP URLs
RewriteRule ^([^/.]+)$ $1.php [L]

        {
            MessageBox.Show(dataGridView1.CurrentCell.Value.ToString());
        }

or

 // dataGrid1.Rows[yourRowIndex ].Cells[yourColumnIndex].Value.ToString()

 //Example1:yourRowIndex=dataGridView1.CurrentRow.Index (from selectedRow );
 dataGrid1.Rows[dataGridView1.CurrentRow.Index].Cells[2].Value.ToString()

 //Example2:yourRowIndex=3,yourColumnIndex=2 (select by programmatically )
  dataGrid1.Rows[3].Cells[2].Value.ToString()

You can also do this without using groupby or loc. By simply including the condition in code. Let the name of dataframe be df. Then you can try :

df[df['a']==1]['b'].sum()

or you can also try :

sum(df[df['a']==1]['b'])

Another way could be to use the numpy library of python :

import numpy as np
print(np.where(df['a']==1, df['b'],0).sum())

If you don't have this ipython_notebook_config.py file, you can create one by following the readme and typing

Felt compelled to answer this because of the other responses. Use empty() if you can because it covers more bases. Future you will thank me.

For example you will have to do things like isset() && strlen() where instead you could use empty(). Think of it like this empty is like !isset($var) || $var==false

Add border-collapse:collapse to the table.

This worked for me.

this is how I handle multiple onClick events inside a recyclerView:

Edit : Updated to include callbacks (as mentioned in other comments). I have used a WeakReference in the ViewHolder to eliminate a potential memory leak.

Define interface :

public interface ClickListener {

    void onPositionClicked(int position);
    
    void onLongClicked(int position);
}

Then the Adapter :

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
    
    private final ClickListener listener;
    private final List<MyItems> itemsList;

    public MyAdapter(List<MyItems> itemsList, ClickListener listener) {
        this.listener = listener;
        this.itemsList = itemsList;
    }

    @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new MyViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.my_row_layout), parent, false), listener);
    }

    @Override public void onBindViewHolder(MyViewHolder holder, int position) {
        // bind layout and data etc..
    }

    @Override public int getItemCount() {
        return itemsList.size();
    }

    public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {

        private ImageView iconImageView;
        private TextView iconTextView;
        private WeakReference<ClickListener> listenerRef;

        public MyViewHolder(final View itemView, ClickListener listener) {
            super(itemView);

            listenerRef = new WeakReference<>(listener);
            iconImageView = (ImageView) itemView.findViewById(R.id.myRecyclerImageView);
            iconTextView = (TextView) itemView.findViewById(R.id.myRecyclerTextView);

            itemView.setOnClickListener(this);
            iconTextView.setOnClickListener(this);
            iconImageView.setOnLongClickListener(this);
        }

        // onClick Listener for view
        @Override
        public void onClick(View v) {

            if (v.getId() == iconTextView.getId()) {
                Toast.makeText(v.getContext(), "ITEM PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(v.getContext(), "ROW PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
            }
            
            listenerRef.get().onPositionClicked(getAdapterPosition());
        }


        //onLongClickListener for view
        @Override
        public boolean onLongClick(View v) {

            final AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());
            builder.setTitle("Hello Dialog")
                    .setMessage("LONG CLICK DIALOG WINDOW FOR ICON " + String.valueOf(getAdapterPosition()))
                    .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                        }
                    });

            builder.create().show();
            listenerRef.get().onLongClicked(getAdapterPosition());
            return true;
        }
    }
}

Then in your activity/fragment - whatever you can implement : Clicklistener - or anonymous class if you wish like so :

MyAdapter adapter = new MyAdapter(myItems, new ClickListener() {
            @Override public void onPositionClicked(int position) {
                // callback performed on click
            }

            @Override public void onLongClicked(int position) {
                // callback performed on click
            }
        });

To get which item was clicked you match the view id i.e. v.getId() == whateverItem.getId()

Hope this approach helps!

There are indeed C# compilers for Android available. Even though I prefer developing Android Apps in Java, I can recommend MonoForAndroid. You find more information on http://xamarin.com/monoforandroid

to insert into DropDownList:

DropDownList.Items.Insert(0, new ListItem("-- Select item --", "0"));

and to remove item from DropDownList:

DropDownList.Items.Remove(new ListItem("-- Select item --", "0"));

if your list looks like this: [1,2,3] you can do:

lst = [1,2,3]
df = pd.DataFrame([lst])
df.columns =['col1','col2','col3']
df

to get this:

    col1    col2    col3
0   1       2       3

alternatively you can create a column as follows:

import numpy as np
df = pd.DataFrame(np.array([lst]).T)
df.columns =['col1']
df

to get this:

  col1
0   1
1   2
2   3

What exactly do you mean by "validation failure"? What are you validating? Are you referring to something like a syntax error (e.g. malformed XML)?

If that's the case, I'd say 400 Bad Request is probably the right thing, but without knowing what it is you're "validating", it's impossible to say.

Assuming you have HTML like this:

<div id='thediv'></div>

If you want to modify the style attribute of this div, you'd use

document.getElementById('thediv').style.[ATTRIBUTE] = '[VALUE]'

Replace [ATTRIBUTE] with the style attribute you want. Remember to remove '-' and make the following letter uppercase.

Examples

document.getElementById('thediv').style.display = 'none'; //changes the display
document.getElementById('thediv').style.paddingLeft = 'none'; //removes padding

If a website's directory does NOT have an "index...." file, AND .htaccess has NOT been used to block access to the directory itself, then Apache will create an "index of" page for that directory. You can save that page, and its icons, using "Save page as..." along with the "Web page, complete" option (Firefox example). If you own the website, temporarily rename any "index...." file, and reference the directory locally. Then restore your "index...." file.

As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)

Duration column = End - Start

1. Once done, plot your stacked bar chart using the entire data.
2. Mark start and end range to no fill.
3. Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))

JSX:

<select value={ this.state.foo } onChange={this.handleFooChange}>
    <option value="A">A</option>
    <option value="B">B</option>
</select>

TypeScript:

private handleFooChange = (event: React.FormEvent<HTMLSelectElement>) => {
    const element = event.target as HTMLSelectElement;
    this.setState({ foo: element.value });
}

With Java 8 it is a bit easier:

OptionalDouble average = marks
            .stream()
            .mapToDouble(a -> a)
            .average();

Thus your average value is average.getAsDouble()

return average.isPresent() ? average.getAsDouble() : 0; 

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }
]

Trying using :

imageview.setFitToScreen(true);
imageview.setScaleType(ScaleType.FIT_CENTER);

This will fit your imageview to the screen with the correct ratio.

Most programs will check the $EDITOR environment variable, so you can set that to the path of TextEdit in your bashrc. Git will use this as well.

How to do this:

• Add the following to your ~/.bashrc file:
  export EDITOR="/Applications/TextEdit.app/Contents/MacOS/TextEdit"
• or just type the following command into your Terminal:
  echo "export EDITOR=\"/Applications/TextEdit.app/Contents/MacOS/TextEdit\"" >> ~/.bashrc

If you are using zsh, use ~/.zshrc instead of ~/.bashrc.

I strongly suspect it's going to be easier to come up with a list of the characters that ARE allowed vs. the ones that aren't -- and once you have that list, the regex syntax becomes quite straightforward. So put me down as another vote for "whitelist".

Update

I also implemented the following solution in my Python script here on GitHub.

I also verified that damaged files (jpg) frequently are not 'broken' images i.e, a damaged picture file sometimes remains a legit picture file, the original image is lost or altered but you are still able to load it with no errors. But, file truncation cause always errors.

End Update

You can use Python Pillow(PIL) module, with most image formats, to check if a file is a valid and intact image file.

In the case you aim at detecting also broken images, @Nadia Alramli correctly suggests the im.verify() method, but this does not detect all the possible image defects, e.g., im.verify does not detect truncated images (that most viewers often load with a greyed area).

Pillow is able to detect these type of defects too, but you have to apply image manipulation or image decode/recode in or to trigger the check. Finally I suggest to use this code:

try:
  im = Image.load(filename)
  im.verify() #I perform also verify, don't know if he sees other types o defects
  im.close() #reload is necessary in my case
  im = Image.load(filename) 
  im.transpose(PIL.Image.FLIP_LEFT_RIGHT)
  im.close()
except: 
  #manage excetions here

In case of image defects this code will raise an exception. Please consider that im.verify is about 100 times faster than performing the image manipulation (and I think that flip is one of the cheaper transformations). With this code you are going to verify a set of images at about 10 MBytes/sec with standard Pillow or 40 MBytes/sec with Pillow-SIMD module (modern 2.5Ghz x86_64 CPU).

For the other formats psd,xcf,.. you can use Imagemagick wrapper Wand, the code is as follows:

im = wand.image.Image(filename=filename)
temp = im.flip;
im.close()

But, from my experiments Wand does not detect truncated images, I think it loads lacking parts as greyed area without prompting.

I red that Imagemagick has an external command identify that could make the job, but I have not found a way to invoke that function programmatically and I have not tested this route.

I suggest to always perform a preliminary check, check the filesize to not be zero (or very small), is a very cheap idea:

statfile = os.stat(filename)
filesize = statfile.st_size
if filesize == 0:
  #manage here the 'faulty image' case

The following adds elements to a list in a loop.

l<-c()
i=1

while(i<100) {

    b<-i
    l<-c(l,b)
    i=i+1
}

Had the same problem on another server, but realized that locales are messed.

export LC_ALL="en_US.UTF-8"

fixed the problem

;WITH tmp(SomeID, OtherID, DataItem, Data) as (
    SELECT SomeID, OtherID, LEFT(Data, CHARINDEX(',',Data+',')-1),
        STUFF(Data, 1, CHARINDEX(',',Data+','), '')
FROM Testdata
WHERE Data > ''
)
SELECT SomeID, OtherID, Data
FROM tmp
ORDER BY SomeID

with only tiny little modification to above query...

Please try Npcap: https://github.com/nmap/npcap, it is based on WinPcap and supports loopback traffic capturing on Windows. Npcap is a subproject of Nmap (http://nmap.org/), so please report any issues on Nmap's development list (http://seclists.org/nmap-dev/).

vuejs 2

v-el:el:uniquename has been replaced by ref="uniqueName". The element is then accessed through this.$refs.uniqueName.

I found this thread useful - so I thought I would add the answer to my own problem.

I wanted to edit a database configuration file (datastax cassandra) from a node application in javascript and for one of the settings in the file I needed to match on a string and then replace the line following it.

This was my solution.

dse_cassandra_yaml='/etc/dse/cassandra/cassandra.yaml'

// a) find the searchString and grab all text on the following line to it
// b) replace all next line text with a newString supplied to function
// note - leaves searchString text untouched
function replaceStringNextLine(file, searchString, newString) {
fs.readFile(file, 'utf-8', function(err, data){
if (err) throw err;
    // need to use double escape '\\' when putting regex in strings !
    var re = "\\s+(\\-\\s(.*)?)(?:\\s|$)";
    var myRegExp = new RegExp(searchString + re, "g");
    var match = myRegExp.exec(data);
    var replaceThis = match[1];
    var writeString = data.replace(replaceThis, newString);
    fs.writeFile(file, writeString, 'utf-8', function (err) {
    if (err) throw err;
        console.log(file + ' updated');
    });
});
}

searchString = "data_file_directories:"
newString = "- /mnt/cassandra/data"

replaceStringNextLine(dse_cassandra_yaml, searchString, newString );

After running, it will change the existing data directory setting to the new one:

config file before:

data_file_directories:  
   - /var/lib/cassandra/data

config file after:

data_file_directories:  
- /mnt/cassandra/data

The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory.

Please see the error below:

 Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

which points to username not getting populated.

Please recheck system properties

dataSource.setUsername(System.getProperty("root"));

some packages seems to be missing as well pointing to a dependency issue:

package org.gjt.mm.mysql does not exist

Please run a mvn dependency:tree command to check for dependencies

I recommend you just use the requests module.

It is much easier than the built in http clients: http://docs.python-requests.org/en/latest/index.html

Sample usage:

r = requests.get('http://www.thepage.com', proxies={"http":"http://myproxy:3129"})
thedata = r.content

This also would work:

export LD_LIBRARY_PATH=/usr/lib/hadoop/lib/native

Try this:

SELECT ProductName,NumberofProducts ,NumberofProductssold
   FROM table1 
     JOIN table2
     ON table1.ProductName = table2.ProductName

What do you want to do with this unique ID? Maybe you can do what you want without this ID.

The MAC address maybe is one option but this is not an trusted unique ID because the user can change the MAC address of a computer.

To get the motherboard or processor ID check on this link.

This page is a neat summary, but is not entirely accurate:

http://findmebyip.com/litmus#target-selector

Edit: This does not work cross domain unless the appropriate CORS header is set.

There are two different things here: the style of the iframe block and the style of the page embedded in the iframe. You can set the style of the iframe block the usual way:

<iframe name="iframe1" id="iframe1" src="empty.htm" 
        frameborder="0" border="0" cellspacing="0"
        style="border-style: none;width: 100%; height: 120px;"></iframe>

The style of the page embedded in the iframe must be either set by including it in the child page:

<link type="text/css" rel="Stylesheet" href="Style/simple.css" />

Or it can be loaded from the parent page with Javascript:

var cssLink = document.createElement("link");
cssLink.href = "style.css"; 
cssLink.rel = "stylesheet"; 
cssLink.type = "text/css"; 
frames['iframe1'].document.head.appendChild(cssLink);

Having a single exit point reduces Cyclomatic Complexity and therefore, in theory, reduces the probability that you will introduce bugs into your code when you change it. Practice however, tends to suggest that a more pragmatic approach is needed. I therefore tend to aim to have a single exit point, but allow my code to have several if that is more readable.

As a noobie I was confused by this until I realized that the so called "path" is the path relative to the MyClass.class file in the file system and not the MyClass.java file. My IDE copies the resources (like xx.jpg, xx.xml) to a directory local to the MyClass.class. For example, inside a pkg directory called "target/classes/pkg. The class-file location may be different for different IDE's and depending on how the build is structured for your application. You should first explore the file system and find the location of the MyClass.class file and the copied location of the associated resource you are seeking to extract. Then determine the path relative to the MyClass.class file and write that as a string value with "dots" and "slashes".

For example, here is how I make an app1.fxml file available to my javafx application where the relevant "MyClass.class" is implicitly "Main.class". The Main.java file is where this line of resource-calling code is contained. In my specific case the resources are copied to a location at the same level as the enclosing package folder. That is: /target/classes/pkg/Main.class and /target/classes/app1.fxml. So paraphrasing...the relative reference "../app1.fxml" is "start from Main.class, go up one directory level, now you can see the resource".

FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("../app1.fxml"));

Note that in this relative-path string "../app1.fxml", the first two dots reference the directory enclosing Main.class and the single "." indicates a file extension to follow. After these details become second nature, you will forget why it was confusing.

First thing first, button() is a jQuery ui function to create a button widget which has nothing to do with jQuery core, it just styles the button.
So if you want to use the widget add jQuery ui's javascript and CSS files or alternatively remove it, like this:

$("#filter").click(function(){
    alert('clicked!');
});

Another thing that might have caused you the problem is if you didn't wait for the input to be rendered and wrote the code before the input. jQuery has the ready function, or it's alias $(func) which execute the callback once the DOM is ready.
Usage:

$(function(){
    $("#filter").click(function(){
        alert('clicked!');
    });
});

So even if the order is this it will work:

$(function(){
    $("#filter").click(function(){
        alert('clicked!');
    });
});

<input type="button" id="filter" name="filter" value="Filter" />

git rm --cached will remove it from the commit set ("un-adding" it); that sounds like what you want.

For Blocks lover you can use ALActionBlocks to add action of gestures in block

__weak ALViewController *wSelf = self;
imageView.userInteractionEnabled = YES;
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithBlock:^(UITapGestureRecognizer *weakGR) {
    NSLog(@"pan %@", NSStringFromCGPoint([weakGR locationInView:wSelf.view]));
}];
[self.imageView addGestureRecognizer:gr];

When you set the Drawable of an ImageView by using the setBackgroundDrawable method, the image will always be scaled. Parameters as adjustViewBounds or different ScaleTypes will just be ignored. The only solution to keep the aspect ratio I found, is to resize the ImageView after loading your drawable. Here is the code snippet I used:

// bmp is your Bitmap object
int imgHeight = bmp.getHeight();
int imgWidth = bmp.getWidth();
int containerHeight = imageView.getHeight();
int containerWidth = imageView.getWidth();
boolean ch2cw = containerHeight > containerWidth;
float h2w = (float) imgHeight / (float) imgWidth;
float newContainerHeight, newContainerWidth;

if (h2w > 1) {
    // height is greater than width
    if (ch2cw) {
        newContainerWidth = (float) containerWidth;
        newContainerHeight = newContainerWidth * h2w;
    } else {
        newContainerHeight = (float) containerHeight;
        newContainerWidth = newContainerHeight / h2w;
    }
} else {
    // width is greater than height
    if (ch2cw) {
        newContainerWidth = (float) containerWidth;
        newContainerHeight = newContainerWidth / h2w; 
    } else {
        newContainerWidth = (float) containerHeight;
        newContainerHeight = newContainerWidth * h2w;       
    }
}
Bitmap copy = Bitmap.createScaledBitmap(bmp, (int) newContainerWidth, (int) newContainerHeight, false);
imageView.setBackgroundDrawable(new BitmapDrawable(copy));
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(params);
imageView.setMaxHeight((int) newContainerHeight);
imageView.setMaxWidth((int) newContainerWidth);

In the code snippet above is bmp the Bitmap object that is to be shown and imageView is the ImageView object

An important thing to note is the change of the layout parameters. This is necessary because setMaxHeight and setMaxWidth will only make a difference if the width and height are defined to wrap the content, not to fill the parent. Fill parent on the other hand is the desired setting at the beginning, because otherwise containerWidth and containerHeight will both have values equal to 0. So, in your layout file you will have something like this for your ImageView:

...
<ImageView android:id="@+id/my_image_view"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>
...

As described elsewhere, perhaps the best solution is to use the logging module directly:

import logging

logging.basicConfig(level=logging.DEBUG, filename='mylog.log')
logging.info('this should to write to the log file')

However, there are some (rare) occasions where you really want to redirect stdout. I had this situation when I was extending django's runserver command which uses print: I didn't want to hack the django source but needed the print statements to go to a file.

This is a way of redirecting stdout and stderr away from the shell using the logging module:

import logging, sys

class LogFile(object):
    """File-like object to log text using the `logging` module."""

    def __init__(self, name=None):
        self.logger = logging.getLogger(name)

    def write(self, msg, level=logging.INFO):
        self.logger.log(level, msg)

    def flush(self):
        for handler in self.logger.handlers:
            handler.flush()

logging.basicConfig(level=logging.DEBUG, filename='mylog.log')

# Redirect stdout and stderr
sys.stdout = LogFile('stdout')
sys.stderr = LogFile('stderr')

print 'this should to write to the log file'

You should only use this LogFile implementation if you really cannot use the logging module directly.

this is one good answer to figure out how sorting works from another user and I will add my notes to know how it is not fully correct and what is correct:

The effect on the formula after a sort is the same as copying. A sort does not move the row contents, it copies them. The formula may (or may not depending on the abs/relative references) use new data, just as a copied formula does.

My point is that if the formula can be copied from 1 row to another and the effects don't change, the sorting will not affect the formula results. If the formulas are so complex and so dependent on position that copying them changes the relative contents, then don't sort them.

And my note that I experienced in practice:

The above user is saying right but in fact It has some exception: parts of a columns formula containing sheet name (like sheet1!A1) are treated as absolute references (in spite of copying that changes the references if they are relative ) so that part of formula will be copied without changing references relative to changing the place of formula This includes current sheet cells addressed fully like : sheet1!A2 and will be treated as absolute references(for sorting only) I tested this of excel 2010 and I do not think this issue be solved in other versions. The solution is to copy and past special as value in another place and then use sorting.

java.exe is associated with the console, whereas javaw.exe doesn't have any such association. So, when java.exe is run, it automatically opens a command prompt window where output and error streams are shown.

If you want to fix quickly, Forward Engineer again and check "Generate DROP SCHEMA" option and proceed.

I assume the database doesn't contain data, so dropping it won't affect.

String.Format("{0:0}", 123.4567);      // "123"

If your initial value is a decimal into a string, you will need to convert

String.Format("{0:0}", double.Parse("3.5", CultureInfo.InvariantCulture))  //3.5

In this example, I choose Invariant culture but you could use the one you want.

I prefer using the Formatting function because you never know if the decimal may contain 2 or 3 leading number in the future.

Edit: You can also use Truncate to remove all after the , or .

Console.WriteLine(Decimal.Truncate(Convert.ToDecimal("3,5")));

User felixhummel got very good solution, but repository with utilite has changed.

In my opinion RecyclerView was made to address the problem with the recycle pattern used in listviews because it was making developer's life more difficult. All the other you could handle more or less. For instance I use the same adapter for ListView and GridView it doesn't matter in both views the getView, getItemCount, getTypeCount is used so it's the same. RecyclerView isn't needed if ListView with ListAdapter or GridView with grid adapters is already working for you. If you have implemented correctly the ViewHolder pattern in your listviews then you won't see any big improvement over RecycleView.

According to PEP8, long lines should be placed in parentheses. When using parentheses, the lines can be broken up without using backslashes. You should also try to put the line break after boolean operators.

Further to this, if you're using a code style check such as pycodestyle, the next logical line needs to have different indentation to your code block.

For example:

if (abcdefghijklmnopqrstuvwxyz > some_other_long_identifier and
        here_is_another_long_identifier != and_finally_another_long_name):
    # ... your code here ...
    pass

You mentioned Ubuntu so I'm going to guess you installed the PostgreSQL packages from Ubuntu through apt.

If so, the postgres PostgreSQL user account already exists and is configured to be accessible via peer authentication for unix sockets in pg_hba.conf. You get to it by running commands as the postgres unix user, eg:

sudo -u postgres createuser owning_user
sudo -u postgres createdb -O owning_user dbname

This is all in the Ubuntu PostgreSQL documentation that's the first Google hit for "Ubuntu PostgreSQL" and is covered in numerous Stack Overflow questions.

(You've made this question a lot harder to answer by omitting details like the OS and version you're on, how you installed PostgreSQL, etc.)

I solved my problem with this code

public void setLocale(String lang) {

        myLocale = new Locale(lang);
        Resources res = getResources();
        DisplayMetrics dm = res.getDisplayMetrics();
        Configuration conf = res.getConfiguration();
        conf.locale = myLocale;
        res.updateConfiguration(conf, dm);

        onConfigurationChanged(conf);
    }



    @Override
    public void onConfigurationChanged(Configuration newConfig) 
    {
        iv.setImageDrawable(getResources().getDrawable(R.drawable.keyboard));
        greet.setText(R.string.greet);
        textView1.setText(R.string.langselection);

        super.onConfigurationChanged(newConfig);

    }

You can use + if you know all the values are strings. Jinja also provides the ~ operator, which will ensure all values are converted to string first.

{% set my_string = my_string ~ stuff ~ ', '%}

This query will help you:

select * 
from XXXX
where datepart(YYYY,create_date)>=2013 
and DATEPART(YYYY,create_date)<=2014

It has 2 purposes.

yentup has given the first one.

It's used for raising your own errors.

if something:
    raise Exception('My error!')

The second is to reraise the current exception in an exception handler, so that it can be handled further up the call stack.

try:
  generate_exception()
except SomeException as e:
  if not can_handle(e):
    raise
  handle_exception(e)

No, you need to wrap your TextBlock in a Border. Example:

<Border BorderThickness="1" BorderBrush="Black">
    <TextBlock ... />
</Border>

Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:

<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Black" />
</Style>

<Border Style="{StaticResource notCalledBorder}">
    <TextBlock ... />
</Border>

You need to set the text after the replace call:

$('.element span').each(function() {_x000D_
  console.log($(this).text());_x000D_
  var text = $(this).text().replace('N/A, ', '');_x000D_
  $(this).text(text);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div class="element">_x000D_
  <span>N/A, Category</span>_x000D_
</div>

Here's another cool way you can do it (hat tip @Felix King):

$(".element span").text(function(index, text) {
    return text.replace("N/A, ", "");
});

From your comments,

the tax amount rounded to the 4th decimal and the total price rounded to the 2nd decimal.

Using the example in the comments, I might foresee a case where you have 400 sales of $1.47. Sales-before-tax would be $588.00, and sales-after-tax would sum to $636.51 (accounting for $48.51 in taxes). However, the sales tax of $0.121275 * 400 would be $48.52.

This was one way, albeit contrived, to force a penny's difference.

I would note that there are payroll tax forms from the IRS where they do not care if an error is below a certain amount (if memory serves, $0.50).

Your big question is: does anybody care if certain reports are off by a penny? If the your specs say: yes, be accurate to the penny, then you should go through the effort to convert to DECIMAL.

I have worked at a bank where a one-penny error was reported as a software defect. I tried (in vain) to cite the software specifications, which did not require this degree of precision for this application. (It was performing many chained multiplications.) I also pointed to the user acceptance test. (The software was verified and accepted.)

Alas, sometimes you just have to make the conversion. But I would encourage you to A) make sure that it's important to someone and then B) write tests to show that your reports are accurate to the degree specified.

for the main question:

call sibling folder as module:

from .. import siblingfolder

call a_file.py from sibling folder as module:

from ..siblingfolder import a_file

call a_function inside a file in sibling folder as module:

from..siblingmodule.a_file import func_name_exists_in_a_file

The easiest way.

go to lib/site-packages folder.

if exists 'easy_install.pth' file, just edit it and add your directory that you have script that you want make it as module.

if not exists, just make it one...and put your folder that you want there

after you add it..., python will be automatically perceive that folder as similar like site-packages and you can call every script from that folder or subfolder as a module.

i wrote this by my phone, and hard to set it to make everyone comfortable to read.

There are two ways I usually do this, both use ssh:

scp -r sourcedir/ [email protected]:/dest/dir/

or, the more robust and faster (in terms of transfer speed) method:

rsync -auv -e ssh --progress sourcedir/ [email protected]:/dest/dir/

Read the man pages for each command if you want more details about how they work.

Updated 2018

For the original question based on Bootstrap 3, the solution was to use push-pull.

In Bootstrap 4 it's now possible to change the order, even when the columns are full-width stacked vertically, thanks to Bootstrap 4 flexbox. OFC, the push pull method will still work, but now there are other ways to change column order in Bootstrap 4, making it possible to re-order full-width columns.

Method 1 - Use flex-column-reverse for xs screens:

<div class="row flex-column-reverse flex-md-row">
    <div class="col-md-3">
        sidebar
    </div>
    <div class="col-md-9">
        main
    </div>
</div>

Method 2 - Use order-first for xs screens:

<div class="row">
    <div class="col-md-3">
        sidebar
    </div>
    <div class="col-md-9 order-first order-md-last">
        main

Bootstrap 4(alpha 6): http://www.codeply.com/go/bBMOsvtJhD
Bootstrap 4.1: https://www.codeply.com/go/e0v77yGtcr

Original 3.x Answer

For the original question based on Bootstrap 3, the solution was to use push-pull for the larger widths, and then the columns will show is their natural order on smaller (xs) widths. (A-B reverse to B-A).

<div class="container">
    <div class="row">
        <div class="col-md-9 col-md-push-3">
            main
        </div>
        <div class="col-md-3 col-md-pull-9">
            sidebar
        </div>
    </div>
</div>

Bootstrap 3: http://www.codeply.com/go/wgzJXs3gel

@emre stated, "You cannot change the order of columns in smaller screens but you can do that in large screens". However, this should be clarified to state: "You cannot change the order of full-width "stacked" columns.." in Bootstrap 3.

To select data in numerical range you can use BETWEEN which is inclusive.

SELECT JOB FROM MYTABLE WHERE ID BETWEEN 10 AND 15;

There's also the PHP UML tool available from pear.

PHP_UML:

• Can generate UML/XMI files in version 1.4, or in version 2.1 (logical, component, and deployment views)
• Can generate an API documentation in HTML format
• Can generate PHP code (code skeleton) from a given XMI file
• Can convert UML/XMI content from version 1.4 to version 2.1

Install it on the command line via:

$ pear install pear/php_uml

(This used to be $ pear install pear/php_uml-alpha but the package has since gone stable.)

Generate your xmi:

$ phpuml -o project.xmi

It's not quite what you asked for, but

git log --graph --simplify-by-decoration --pretty=format:'%d' --all

does a pretty good job. It shows tags and remote branches as well. This may not be desirable for everyone, but I find it useful. --simplifiy-by-decoration is the big trick here for limiting the refs shown.

I use a similar command to view my log. I've been able to completely replace my gitk usage with it:

git log --graph --oneline --decorate --all

I use it by including these aliases in my ~/.gitconfig file:

[alias]
    l = log --graph --oneline --decorate
    ll = log --graph --oneline --decorate --branches --tags
    lll = log --graph --oneline --decorate --all

Edit: Updated suggested log command/aliases to use simpler option flags.

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

That error usually occurs when you try to subtract an interval from DateTime.MinValue or you want to add something to DateTime.MaxValue (or you try to instantiate a date outside this min-max interval). Are you sure you're not assigning MinValue somewhere?

A cleaner format FQDN remotely

[System.Net.Dns]::GetHostByName('remotehost').HostName

If the server is running as the foreground process in a terminal, this can be done by pressing

Ctrl-C

Another way to cleanly shut down a running server is to use the shutdown command,

> use admin
> db.shutdownServer();

Otherwise, a command like kill can be used to send the signal. If mongod has 10014 as its PID, the command would be

kill -2 10014

This will work everywhere.

I have found a simple solution which worked for me.

String.Join(",",str.Split(','));

Thanks for all the Hints. Using Tomcat8 I also added a filter like @Jasper de Vries wrote. But in the newer Tomcats nowadays there is a filter already implemented that can be used resp just uncommented in the Tomcat web.xml:

<filter>
    <filter-name>setCharacterEncodingFilter</filter-name>
    <filter-class>org.apache.catalina.filters.SetCharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <async-supported>true</async-supported>
</filter>
...
<filter-mapping>
    <filter-name>setCharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

And like all others posted; I added the URIEncoding="UTF-8" to the Tomcat Connector in Apache. That also helped.

Important to say, that Eclipse (if you use this) has a copy of its web.xml and overwrites the Tomcat-Settings as it was explained here: Broken UTF-8 URI Encoding in JSPs

For me this error occurred because I had 2 web API actions that had the exact same signatures and both had the same verbs, HttpPost, what I did was change one of the verbs (the one used for updating) to PUT and the error was removed. The following in my catch statement helped in getting to the root of the problem:

catch (WebException webex)
{
                WebResponse errResp = webex.Response;
                using (Stream respStream = errResp.GetResponseStream())
                {
                    StreamReader reader = new StreamReader(respStream);
                    string text = reader.ReadToEnd();
                }
}

If you have questions about creating React App I encourage you to read its User Guide.
It answers this and many other questions you may have.

Specifically, to include a local image you have two options:

1. Use imports:

   // Assuming logo.png is in the same folder as JS file
   import logo from './logo.png';
   
   // ...later
   <img src={logo} alt="logo" />
   

This approach is great because all assets are handled by the build system and will get filenames with hashes in the production build. You’ll also get an error if the file is moved or deleted.

The downside is it can get cumbersome if you have hundreds of images because you can’t have arbitrary import paths.

2. Use the public folder:

   // Assuming logo.png is in public/ folder of your project
   <img src={process.env.PUBLIC_URL + '/logo.png'} alt="logo" />
   

This approach is generally not recommended, but it is great if you have hundreds of images and importing them one by one is too much hassle. The downside is that you have to think about cache busting and watch out for moved or deleted files yourself.

Hope this helps!

ES5 // Check Deeply Nested Variables

This simple piece of code can check for deeply nested variable / value existence without having to check each variable along the way...

var getValue = function( s, context ){
    return Function.call( context || null, 'return ' + s )();
}

Ex. - a deeply nested array of objects:

a = [ 
    {
      b : [
          {
             a : 1,
             b : [
                 {
                    c : 1,
                    d : 2   // we want to check for this
                 }
             ]
           }
      ]
    } 
]

Instead of :

if(a && a[0] && a[0].b && a[0].b[0] && a[0].b[0].b && a[0].b[0].b[0] && a[0].b[0].b[0].d && a[0].b[0].b[0].d == 2 )  // true

We can now :

if( getValue('a[0].b[0].b[0].d') == 2 ) // true

Cheers!

Note that setUserVisibleHint(false) is not called on activity / fragment stop. You'll still need to check start/stop to properly register/unregister any listeners/etc.

Also, you'll get setUserVisibleHint(false) if your fragment starts in a non-visible state; you don't want to unregister there since you've never registered before in that case.

@Override
public void onStart() {
    super.onStart();

    if (getUserVisibleHint()) {
        // register
    }
}

@Override
public void onStop() {
    if (getUserVisibleHint()) {
        // unregister
    }

    super.onStop();
}

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);

    if (isVisibleToUser && isResumed()) {
        // register

        if (!mHasBeenVisible) {
            mHasBeenVisible = true;
        }
    } else if (mHasBeenVisible){
        // unregister
    }
}

Kevlar is correct.

I'm having the same problem with Wampserver. It’s worked for me:

You must change this file: "C:\wamp\bin\mysql[mysql_version]\my.ini" For example: "C:\wamp\bin\mysql[mysql5.6.12]\my.ini"

And change default port 3306 to 80. (Lines 20 & 27, in both)

port = 3306 To port = 80

I hope this is helpful.

In ASP.NET Core 2.2 and later we can inject IConfiguration anywhere in our application like in your case, you can inject IConfiguration in HomeController and use like this to get the array.

string[] array = _config.GetSection("MyArray").Get<string[]>();

for i in `cat Hostlist`
do  
  ping -c1 -w2 $i | grep "PING" | awk '{print $2,$3}'
done

Based on @epegzz suggestion for the regex.

( url ) => {
  return url.match('^[^?]*')[0].split('/').slice(1)
}

returns an array with paths.

This is an old question, but I stumbled onto this when looking for the answer so I wanted to give the update to the answer for reference.

The methods save and update are deprecated.

save(to_save, manipulate=True, check_keys=True, **kwargs)¶ Save a document in this collection.

DEPRECATED - Use insert_one() or replace_one() instead.

Changed in version 3.0: Removed the safe parameter. Pass w=0 for unacknowledged write operations.

update(spec, document, upsert=False, manipulate=False, multi=False, check_keys=True, **kwargs) Update a document(s) in this collection.

DEPRECATED - Use replace_one(), update_one(), or update_many() instead.

Changed in version 3.0: Removed the safe parameter. Pass w=0 for unacknowledged write operations.

in the OPs particular case, it's better to use replace_one.

SQL Server requires subqueries that you SELECT FROM or JOIN to have an alias.

Add an alias to your subquery (in this case x):

select COUNT(*) from
(
select m.Company_id
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5)  x

What's the problem , in fact ?

If you really need or want 10 a, b, c, d, e, f, g, h, i, j , there will be no other possibility, at a time or another, to write a and write b and write c.....

If the values are all different, you will be obliged to write for exemple

a = 12
b= 'sun'
c = A() #(where A is a class)
d = range(1,102,5)
e = (line in filehandler if line.rstrip())
f = 0,12358
g = True
h = random.choice
i = re.compile('^(!=  ab).+?<span>')
j = [78,89,90,0]

that is to say defining the "variables" individually.

Or , using another writing, no need to use _ :

a,b,c,d,e,f,g,h,i,j =\
12,'sun',A(),range(1,102,5),\
(line for line in filehandler if line.rstrip()),\
0.12358,True,random.choice,\
re.compile('^(!=  ab).+?<span>'),[78,89,90,0]

or

a,b,c,d,e,f,g,h,i,j =\
(12,'sun',A(),range(1,102,5),
 (line for line in filehandler if line.rstrip()),
 0.12358,True,random.choice,
 re.compile('^(!=  ab).+?<span>'),[78,89,90,0])

.

If some of them must have the same value, is the problem that it's too long to write

a, b, c, d, e, f, g, h, i, j = True, True, True, True, True, False, True ,True , True, True 

?

Then you can write:

a=b=c=d=e=g=h=i=k=j=True
f = False

.

I don't understand what is exactly your problem. If you want to write a code, you're obliged to use the characters required by the writing of the instructions and definitions. What else ?

I wonder if your question isn't the sign that you misunderstand something.

When one writes a = 10 , one don't create a variable in the sense of "chunk of memory whose value can change". This instruction:

• either triggers the creation of an object of type integer and value 10 and the binding of a name 'a' with this object in the current namespace

• or re-assign the name 'a' in the namespace to the object 10 (because 'a' was precedently binded to another object)

I say that because I don't see the utility to define 10 identifiers a,b,c... pointing to False or True. If these values don't change during the execution, why 10 identifiers ? And if they change, why defining the identifiers first ?, they will be created when needed if not priorly defined

Your question appears weird to me

Schleis' variant does not work for me (Ubuntu 12.04), so let me propose my (clear and shiny :) variants:

Variant 1 (I would prefer this option):

git for-each-ref --format='%(refname:short) %(upstream)' refs/heads/ | awk '$2 !~/^refs\/remotes/' | xargs git branch -D 

Variant 2:

a. Dry-run:

comm -23 <( git branch | grep -v "/" | grep -v "*" | sort ) <( git br -r | awk -F '/' '{print $2}' | sort ) | awk '{print "git branch -D " $1}'

b. Remove branches:

comm -23 <( git branch | grep -v "/" | grep -v "*" | sort ) <( git br -r | awk -F '/' '{print $2}' | sort ) | xargs git branch -D

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100, say, and your current client IDs are in Sheet1 in Column A.

What you would do is:

1. Select the whole data table you want conditionally formatted in Sheet1
2. Click Conditional Formatting > New Rule > Use a Formula to determine which cells to format
3. In the formula bar, type in =ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0)) and select how you want those rows formatted

And that should do the trick.

Here is the sample worked in Python: This sample returns the results inline.

from pymongo import MongoClient
from bson.code import Code

mapper = Code("""
    function() {
                  for (var key in this) { emit(key, null); }
               }
""")
reducer = Code("""
    function(key, stuff) { return null; }
""")

distinctThingFields = db.things.map_reduce(mapper, reducer
    , out = {'inline' : 1}
    , full_response = True)
## do something with distinctThingFields['results']

In my case I had two version of "android-support-v4.jar" references in the project. After resolving this (removed additional/incorrect reference) solved the issue.

Careful! Watch the accessibility of your classes. Public and protected classes and methods are by default accessible for everyone.

Also, Microsoft isn't very explicit in showing access modifiers (public, protected, etc.. keywords) when new classes in Visual Studio are created. So, take good care and think about the accessibility of your class because it's the door to your implementation internals.

In this case, why not use new File("prefix/dir1/dir2/dir3/dir4") and go from there?

Check out SQL For Smarties. I thought I was pretty good with SQL too, until I read that book... Goes into tons of depth, talks about things I've not seen elsewhere (I.E. difference between 3'rd and 4'th normal form, Boyce Codd Normal Form, etc)...

Make sure to double the entry with an additional "www"-prefix. If you don't addresses like "www.acme.com" will not work!

If you want to have access to the id attribute of the button you can leverage the srcElement property of the event:

import {Component} from 'angular2/core';

@Component({
  selector: 'my-app',
  template: `
    <button (click)="onClick($event)" id="test">Click</button>
  `
})
export class AppComponent {
  onClick(event) {
    var target = event.target || event.srcElement || event.currentTarget;
    var idAttr = target.attributes.id;
    var value = idAttr.nodeValue;
  }
}

See this plunkr: https://plnkr.co/edit/QGdou4?p=preview.

See this question:

• How can I make event.srcElement work in Firefox and what does it mean?

>>> for line in s.splitlines():
...     line = line.strip()
...     if not line:continue
...     ary.append(line.split(":"))
...

]]
>>> dict(ary)
{'Home': ' Anytown USA', 'Misc': ' Data with spaces', 'Name': ' John Smith'}

For those who just need to save some int value in the resources, you can do the following.

integers.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer name="default_value">100</integer>
</resources> 

Code

int defaultValue = getResources().getInteger(R.integer.default_value);

Look at the yesno helper

Eg:

{{ myValue|yesno:"itwasTrue,itWasFalse,itWasNone" }}

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

Here you have used native and assigning value to the primary key, in native primary key is auto generated.

Hence the issue is coming.

def listToStringWithoutBrackets(list1):
    return str(list1).replace('[','').replace(']','')

Why not so?:

set host=%COMPUTERNAME%
echo %host%

Just for fun:

#!/bin/bash

FILE=$1

if [[ -z $FILE ]]; then
   echo "You must pass a filename -- exiting" >&2
   exit 1
fi

if [[ ! -f $FILE ]]; then
   echo "There is not file '$FILE' here -- exiting" >&2
   exit 1
fi

BEFORE=`wc -c "$FILE" | cut --delimiter=' ' --fields=1`

# >>>>>>>>>>
sed -i.bak -e's/[ \t]*$//' "$FILE"
# <<<<<<<<<<

AFTER=`wc -c "$FILE" | cut --delimiter=' ' --fields=1`

if [[ $? != 0 ]]; then
   echo "Some error occurred" >&2
else
   echo "Filtered '$FILE' from $BEFORE characters to $AFTER characters"
fi

The correct answer, is to use a class and put the value inside the class, this lets you pass by reference exactly as you desire.

class Thing:
  def __init__(self,a):
    self.a = a
def dosomething(ref)
  ref.a += 1

t = Thing(3)
dosomething(t)
print("T is now",t.a)

I recompiled the package specification, even though the change was only in the package body. This resolved my issue

For me it was really silly I had created a ModelClass file without the .php extension. So calling that was giving model not found. So check the extension has .php

Here is the best way I found for Python 2:

def inplace_change(file,old,new):
        fin = open(file, "rt")
        data = fin.read()
        data = data.replace(old, new)
        fin.close()

        fin = open(file, "wt")
        fin.write(data)
        fin.close()

An example:

inplace_change('/var/www/html/info.txt','youtub','youtube')

HTMLInputElement.setSelectionRange( selectionStart, selectionEnd );

// References
var e = document.getElementById( "helloworldinput" );

// Move caret to beginning on focus
e.addEventListener( "focus", function( event )
{
    // References
    var e = event.target;

    // Action
    e.setSelectionRange( 0, 0 );            // Doesn’t work for focus event
    
    window.setTimeout( function()
    {
        e.setSelectionRange( 0, 0 );        // Works
        //e.setSelectionRange( 1, 1 );      // Move caret to second position
        //e.setSelectionRange( 1, 2 );      // Select second character

    }, 0 );

}, false );

Verify if your packageName is correct. You have to refer for the root package of your Android application.

private String getStringResourceByName(String aString) {
      String packageName = getPackageName();
      int resId = getResources().getIdentifier(aString, "string", packageName);
      return getString(resId);
    }

<TextView android:alpha="0.3" ..., for example.

You can simplify things quite a bit by creating a class that derives from WebClient, overriding its GetWebRequest method and setting a CookieContainer object on it. If you always set the same CookieContainer instance, then cookie management will be handled automatically for you.

But the only way to get at the HttpWebRequest before it is sent is to inherit from WebClient and override that method.

public class CookieAwareWebClient : WebClient
{
    private CookieContainer cookie = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = cookie;
        }
        return request;
    }
}

var client = new CookieAwareWebClient();
client.BaseAddress = @"https://www.site.com/any/base/url/";
var loginData = new NameValueCollection();
loginData.Add("login", "YourLogin");
loginData.Add("password", "YourPassword");
client.UploadValues("login.php", "POST", loginData);

//Now you are logged in and can request pages    
string htmlSource = client.DownloadString("index.php");

In my case, I was getting error connecting to AWS Gov Postgres RDS. There is a separate link for GOV RDS CA certs- https://s3.us-gov-west-1.amazonaws.com/rds-downloads/rds-combined-ca-us-gov-bundle.pem

Add this pem certs to cacerts of java. You can use below script.

------WINDOWDS STEPS-------

1. Use VSCODE editor and install openssl, keytool plugins
2. create a dir in C:/rds-ca
3. place 'cacerts' file and below script file - 'addCerts.sh' inside dir 'rd-ca'
4. run from vscode: 4.1 cd /c/rds-ca/ 4.2 ./addCerts.sh
5. Copy cacerts to ${JAVA_HOME}/jre/lib/security

Script code:

#!/usr/bin/env sh

OLDDIR="$PWD"

CACERTS_FILE=cacerts

cd /c/rds-ca

echo "Downloading RDS certificates..."

curl  https://s3.us-gov-west-1.amazonaws.com/rds-downloads/rds-combined-ca-us-gov-bundle.pem > rds-combined-ca-bundle.pem

csplit -sk rds-combined-ca-bundle.pem "/-BEGIN CERTIFICATE-/" "{$(grep -c 'BEGIN CERTIFICATE' rds-combined-ca-bundle.pem | awk '{print $1 - 2}')}"

for CERT in xx*; do
    # extract a human-readable alias from the cert
    ALIAS=$(openssl x509 -noout -text -in $CERT |
                   perl -ne 'next unless /Subject:/; s/.*CN=//; print')
    echo "importing $ALIAS"
    
    keytool -import \
            -keystore  $CACERTS_FILE \
            -storepass changeit -noprompt \
            -alias "$ALIAS" -file $CERT
done

cd "$OLDDIR"
echo "$NEWDIR"

You can use following script to get the path without trailing "\"

for %%i in ("%~dp0.") do SET "mypath=%%~fi"

This is an old question, but this may help Mac users.

If you are copying files from Time Machine manually, instead of restoring them through Time Machine, it'll add ACLs to everything, which can mess up your permissions.

For example, the section in this article that says "How to Fix Mac OS X File Permissions" shows that "everyone" has custom permissions, which messes it all up:

You need to remove the ACLs from those directories/files. This Super User answer goes into it, but here's the command:

sudo chmod -RN .

Then you can make sure your directories and files have the proper permissions. I use 750 for directories and 644 for files.

If the checkbox is checked you will get a value for it in your $_POST array. If it isn't the element will be omitted from the array altogether.

The easiest way to test it is like this:

if (isset($_POST['myCheckbox'])) {
  $checkBoxValue = "yes";
} else {
  $checkBoxValue = "no";
}

For your code, add it immediately below the other preprocessing:

$name = $_POST['name']; 
$email_address = $_POST['email']; 
$message = $_POST['tel']; 

if (isset($_POST['newsletter'])) {
  $newsletter = "yes";
} else {
  $newsletter = "no";
}

You'll also need to change the HTML slightly. Change this line:

<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up for newsletter<br>

to this:

<input type="checkbox" name="newsletter" value="newsletter" checked>i want to sign up   for newsletter<br>
                                      ^^^ remove square brackets here.

If you can use project configurations in all your environments, that would make defining a 64- and 32-bit symbol easy. So you'd have project configurations like this:

32-bit Debug
32-bit Release
64-bit Debug
64-bit Release

EDIT: These are generic configurations, not targetted configurations. Call them whatever you want.

If you can't do that, I like Jared's idea.

I see my problem is a little bit different from yours, but I'll post this answer in case it helps someone else. I was using MB as shorthand instead of M when defining my memory_limit, and php was silently ignoring it. I changed it to an integer (in bytes) and the problem was solved.

My php.ini changed as follows: memory_limit = 512MB to memory_limit = 536870912. This fixed my problem. Hope it helps with someone else's! You can read up on php's shorthand here.

Good luck!

Edit

As Yaodong points out, you can just as easily use the correct shorthand, "M", instead of using byte values. I changed mine to byte values for debugging purposes and then didn't bother to change it back.

Unless you let eval() a dynamic content (through cgi or input), it is as safe and solid as all other JavaScript in your page.

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

You can use this command to quit an app in iOS Simulator

xcrun simctl terminate booted com.apple.mobilesafari

You will need to know the bundle id of the app you have installed in the simulator. You can refer to this link

To get the current directory, you can use this:

CD > tmpFile
SET /p myvar= < tmpFile
DEL tmpFile
echo test: %myvar%

It's using a temp-file though, so it's not the most pretty, but it certainly works! 'CD' puts the current directory in 'tmpFile', 'SET' loads the content of tmpFile.

Here is a solution for multiple lines with "array's":

@echo off

rem ---------
rem Obtain line numbers from the file
rem ---------

rem This is the file that is being read: You can replace this with %1 for dynamic behaviour or replace it with some command like the first example i gave with the 'CD' command.
set _readfile=test.txt

for /f "usebackq tokens=2 delims=:" %%a in (`find /c /v "" %_readfile%`) do set _max=%%a
set /a _max+=1
set _i=0
set _filename=temp.dat

rem ---------
rem Make the list
rem ---------

:makeList
find /n /v "" %_readfile% >%_filename%

rem ---------
rem Read the list
rem ---------

:readList
if %_i%==%_max% goto printList

rem ---------
rem Read the lines into the array
rem ---------
for /f "usebackq delims=] tokens=2" %%a in (`findstr /r "\[%_i%]" %_filename%`) do set _data%_i%=%%a
set /a _i+=1
goto readList

:printList
del %_filename%
set _i=1
:printMore
if %_i%==%_max% goto finished
set _data%_i%
set /a _i+=1
goto printMore

:finished

But you might want to consider moving to another more powerful shell or create an application for this stuff. It's stretching the possibilities of the batch files quite a bit.

str = "Tue, 10 Aug 2010 01:20:19 -0400 (EDT)"

Use random.uniform(a, b):

>>> random.uniform(1.5, 1.9)
1.8733202628557872

There are plenty of clients actually. One of them is Pest - check this out. And keep in mind that these REST calls are simple http request with various methods: GET, POST, PUT and DELETE.

just vars(obj) , it will state the whole values of the object

>>> obj_attrs = vars(obj)
>>> obj_attrs
 {'_file_data_cache': <FileData: Data>,
  '_state': <django.db.models.base.ModelState at 0x7f5c6733bad0>,
  'aggregator_id': 24,
  'amount': 5.0,
  'biller_id': 23,
  'datetime': datetime.datetime(2018, 1, 31, 18, 43, 58, 933277, tzinfo=<UTC>),
  'file_data_id': 797719,
 }

You can add this also

>>> keys = obj_attrs.keys()
>>> temp = [obj_attrs.pop(key) if key.startswith('_') else None for key in keys]
>>> del temp
>>> obj_attrs
   {
    'aggregator_id': 24,
    'amount': 5.0,
    'biller_id': 23,
    'datetime': datetime.datetime(2018, 1, 31, 18, 43, 58, 933277, tzinfo=<UTC>),
    'file_data_id': 797719,
   }

I came across this when I started using three.js as well. It's actually a javascript issue. You currently have:

renderer.setClearColorHex( 0x000000, 1 );

in your threejs init function. Change it to:

renderer.setClearColorHex( 0xffffff, 1 );

Update: Thanks to HdN8 for the updated solution:

renderer.setClearColor( 0xffffff, 0);

Update #2: As pointed out by WestLangley in another, similar question - you must now use the below code when creating a new WebGLRenderer instance in conjunction with the setClearColor() function:

var renderer = new THREE.WebGLRenderer({ alpha: true });

Update #3: Mr.doob points out that since r78 you can alternatively use the code below to set your scene's background colour:

var scene = new THREE.Scene(); // initialising the scene
scene.background = new THREE.Color( 0xff0000 );

    <select>
         <option value="" disabled="disabled" selected="selected">Please select a 
              developer position</option>
          <option value="1">Beginner</option>
          <option value="2">Expert</option>
     </select>

You can use the csv module to parse tab seperated value files easily.

import csv

with open("tab-separated-values") as tsv:
    for line in csv.reader(tsv, dialect="excel-tab"): #You can also use delimiter="\t" rather than giving a dialect.
        ... 

Where line is a list of the values on the current row for each iteration.

Edit: As suggested below, if you want to read by column, and not by row, then the best thing to do is use the zip() builtin:

with open("tab-separated-values") as tsv:
    for column in zip(*[line for line in csv.reader(tsv, dialect="excel-tab")]):
        ...

My solution to this issue in my spring boot application was to open the spring application context and adding the class for the missing autowired bean manually!

(access via Project Structure menu or spring tool window... edit "Spring Application Context")

So instead of SpringApplicationContext just containing my ExampleApplication spring configuration it also contains the missing Bean:

SpringApplicationContext:

• ExampleApplication.java
• MissingBeanClass.java

et voilà: The error message disappeared!

It's useful to work with Deferred Object in this case, and return promise:

function readImage(inputElement) {
    var deferred = $.Deferred();

    var files = inputElement.get(0).files;
    if (files && files[0]) {
        var fr= new FileReader();
        fr.onload = function(e) {
            deferred.resolve(e.target.result);
        };
        fr.readAsDataURL( files[0] );
    } else {
        deferred.resolve(undefined);
    }

    return deferred.promise();
}

And above function could be used in this way:

var inputElement = $("input[name=file]");
readImage(inputElement).done(function(base64Data){
    alert(base64Data);
});

Or in your case:

$(input).on('change',function(){
  readImage($(this)).done(function(base64Data){ alert(base64Data); });
});

we starting from conversion [ JSONArray -> List < JSONObject > ]

public static List<JSONObject> getJSONObjectListFromJSONArray(JSONArray array) 
        throws JSONException {
  ArrayList<JSONObject> jsonObjects = new ArrayList<>();
  for (int i = 0; 
           i < (array != null ? array.length() : 0);           
           jsonObjects.add(array.getJSONObject(i++)) 
       );
  return jsonObjects;
}

next create generic version replacing array.getJSONObject(i++) with POJO

example :

public <T> static List<T> getJSONObjectListFromJSONArray(Class<T> forClass, JSONArray array) 
        throws JSONException {
  ArrayList<Tt> tObjects = new ArrayList<>();
  for (int i = 0; 
           i < (array != null ? array.length() : 0);           
           tObjects.add( (T) createT(forClass, array.getJSONObject(i++))) 
       );
  return tObjects;
}

private static T createT(Class<T> forCLass, JSONObject jObject) {
   // instantiate via reflection / use constructor or whatsoever 
   T tObject = forClass.newInstance(); 
   // if not using constuctor args  fill up 
   // 
   // return new pojo filled object 
   return tObject;
}

I always just use sc.exe (see http://support.microsoft.com/kb/251192). It should be installed on XP from SP1, and if it's not in your flavor of Vista, you can download load it with the Vista resource kit.

I haven't done anything too complicated with Java, but using either a fully qualified command line argument (x:\java.exe ....) or creating a script with Ant to include depencies and set parameters works fine for me.

The full list of readyState values is:

State  Description
0      The request is not initialized
1      The request has been set up
2      The request has been sent
3      The request is in process
4      The request is complete

(from https://www.w3schools.com/js/js_ajax_http_response.asp)

In practice you almost never use any of them except for 4.

Some XMLHttpRequest implementations may let you see partially received responses in responseText when readyState==3, but this isn't universally supported and shouldn't be relied upon.

The error message is telling you.

Try just

"C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe" /t "$pdf"

When you enclose the string in single-quotes, this makes everything inside a valid string, including the " chars. By removing the single-quotes, the shell will process the dbl-quotes as string "wrappers".

I would also wrap the filename variable in dbl-quotes so you can easily process files with spaces in their names, i.e.

"C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe" /t "$pdf"

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

tl;dr: JavaScript doesn't support associative arrays, therefore neither does JSON.

After all, it's JSON, not JSAAN. :)

So PHP has to convert your array into an object in order to encode into JSON.

ArrayList does increases the size on load factor on following cases:

• Initial Capacity: 10
• Load Factor: 1 (i.e. when the list is full)
• Growth Rate: current_size + current_size/2

Context : JDK 7

While adding an element into the ArrayList, the following public ensureCapacityInternal calls and the other private method calls happen internally to increase the size. This is what dynamically increase the size of ArrayList. while viewing the code you can understand the logic by naming conventions, because of this reason I am not adding explicit description

public boolean add(E paramE) {
        ensureCapacityInternal(this.size + 1);
        this.elementData[(this.size++)] = paramE;
        return true;
    }

private void ensureCapacityInternal(int paramInt) {
        if (this.elementData == EMPTY_ELEMENTDATA)
            paramInt = Math.max(10, paramInt);
        ensureExplicitCapacity(paramInt);
    }
private void ensureExplicitCapacity(int paramInt) {
        this.modCount += 1;
        if (paramInt - this.elementData.length <= 0)
            return;
        grow(paramInt);
    }

private void grow(int paramInt) {
    int i = this.elementData.length;
    int j = i + (i >> 1);
    if (j - paramInt < 0)
        j = paramInt;
    if (j - 2147483639 > 0)
        j = hugeCapacity(paramInt);
    this.elementData = Arrays.copyOf(this.elementData, j);
}

You need formulas to convert latitude and longitude to rectangular coordinates. There are a great number to choose from and each will distort the map in a different way. Wolfram MathWorld has a good collection:

Follow the "See Also" links.

Datanewolf's code is ALMOST right. I had to reverse both the winding and the normals to make it work properly with the fixed pipeline. The below works correctly with cull on or off for me:

std::vector<GLfloat> vertices;
std::vector<GLfloat> normals;
std::vector<GLfloat> texcoords;
std::vector<GLushort> indices;

float const R = 1./(float)(rings-1);
float const S = 1./(float)(sectors-1);
int r, s;

vertices.resize(rings * sectors * 3);
normals.resize(rings * sectors * 3);
texcoords.resize(rings * sectors * 2);
std::vector<GLfloat>::iterator v = vertices.begin();
std::vector<GLfloat>::iterator n = normals.begin();
std::vector<GLfloat>::iterator t = texcoords.begin();
for(r = 0; r < rings; r++) for(s = 0; s < sectors; s++) {
    float const y = sin( -M_PI_2 + M_PI * r * R );
    float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
    float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

    *t++ = s*S;
    *t++ = r*R;

    *v++ = x * radius;
    *v++ = y * radius;
    *v++ = z * radius;

    *n++ = -x;
    *n++ = -y;
    *n++ = -z;
}

indices.resize(rings * sectors * 4);
std::vector<GLushort>::iterator i = indices.begin();
for(r = 0; r < rings-1; r++)
    for(s = 0; s < sectors-1; s++) {
       /* 
        *i++ = r * sectors + s;
        *i++ = r * sectors + (s+1);
        *i++ = (r+1) * sectors + (s+1);
        *i++ = (r+1) * sectors + s;
        */
         *i++ = (r+1) * sectors + s;
         *i++ = (r+1) * sectors + (s+1);
        *i++ = r * sectors + (s+1);
         *i++ = r * sectors + s;

}

Edit: There was a question on how to draw this... in my code I encapsulate these values in a G3DModel class. This is my code to setup the frame, draw the model, and end it:

void GraphicsProvider3DPriv::BeginFrame()const{
        int win_width;
        int win_height;// framework of choice here
        glfwGetWindowSize(window, &win_width, &win_height); // retrieve window
        float const win_aspect = (float)win_width / (float)win_height;
        // set lighting
        glEnable(GL_LIGHTING);
        glEnable(GL_LIGHT0);
        glEnable(GL_DEPTH_TEST);
        GLfloat lightpos[] = {0, 0.0, 0, 0.};
        glLightfv(GL_LIGHT0, GL_POSITION, lightpos);
        GLfloat lmodel_ambient[] = { 0.2, 0.2, 0.2, 1.0 };
        glLightModelfv(GL_LIGHT_MODEL_AMBIENT, lmodel_ambient);
        glLightModeli(GL_LIGHT_MODEL_TWO_SIDE, GL_TRUE);
        // set up world transform
        glClearColor(0.f, 0.f, 0.f, 1.f);
        glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT|GL_ACCUM_BUFFER_BIT);
        glMatrixMode(GL_PROJECTION);
        glLoadIdentity();

        gluPerspective(45, win_aspect, 1, 10);

        glMatrixMode(GL_MODELVIEW);

    }


    void GraphicsProvider3DPriv::DrawModel(const G3DModel* model, const Transform3D transform)const{
        G3DModelPriv* privModel = (G3DModelPriv *)model;
        glPushMatrix();
        glLoadMatrixf(transform.GetOGLData());

        glEnableClientState(GL_VERTEX_ARRAY);
        glEnableClientState(GL_NORMAL_ARRAY);
        glEnableClientState(GL_TEXTURE_COORD_ARRAY);

        glVertexPointer(3, GL_FLOAT, 0, &privModel->vertices[0]);
        glNormalPointer(GL_FLOAT, 0, &privModel->normals[0]);
        glTexCoordPointer(2, GL_FLOAT, 0, &privModel->texcoords[0]);

        glEnable(GL_TEXTURE_2D);
        //glFrontFace(GL_CCW);
        glEnable(GL_CULL_FACE);
        glActiveTexture(GL_TEXTURE0);
        glBindTexture(GL_TEXTURE_2D, privModel->texname);

        glDrawElements(GL_QUADS, privModel->indices.size(), GL_UNSIGNED_SHORT, &privModel->indices[0]);
        glPopMatrix();
        glDisable(GL_TEXTURE_2D);

    }

    void GraphicsProvider3DPriv::EndFrame()const{
        /* Swap front and back buffers */
        glDisable(GL_LIGHTING);
        glDisable(GL_LIGHT0);
        glDisable(GL_CULL_FACE);
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

querySelector is of w3c Selector API

getElementBy is of w3c DOM API

IMO the most notable difference is that the return type of querySelectorAll is a static node list and for getElementsBy it's a live node list. Therefore the looping in demo 2 never ends because lis is live and updates itself during each iteration.

// Demo 1 correct
var ul = document.querySelectorAll('ul')[0],
    lis = ul.querySelectorAll("li");
for(var i = 0; i < lis.length ; i++){
    ul.appendChild(document.createElement("li"));
}

// Demo 2 wrong
var ul = document.getElementsByTagName('ul')[0], 
    lis = ul.getElementsByTagName("li"); 
for(var i = 0; i < lis.length ; i++){
    ul.appendChild(document.createElement("li")); 
}

If you want your TextBox uneditable you should make it ReadOnly.

While this is one of the most voted feature requests, there is one plugin available, by Victor Kropp, that adds support to makefiles:

Makefile support plugin for IntelliJ IDEA

Install

You can install directly from the official repository:

Settings > Plugins > search for makefile > Search in repositories > Install > Restart

Use

There are at least three different ways to run:

1. Right click on a makefile and select Run
2. Have the makefile open in the editor, put the cursor over one target (anywhere on the line), hit alt + enter, then select make target
3. Hit ctrl/cmd + shift + F10 on a target (although this one didn't work for me on a mac).

It opens a pane named Run target with the output.

See the javadoc

of List

list.get(0);

or Set

set.iterator().next();

and check the size before using the above methods by invoking isEmpty()

!list_or_set.isEmpty()

Tuple classes allow developers to be 'quick and lazy' by not defining a specific class for a specific use.

The property names are Item1, Item2, Item3 ..., which may not be meaningful in some cases or without documentation.

Tuple classes have strongly typed generic parameters. Still users of the Tuple classes may infer from the type of generic parameters.

@alvas's answer does the job but it can be done way faster. Assuming that you have documents: a list of strings.

from nltk.corpus import stopwords
from nltk.tokenize import wordpunct_tokenize

stop_words = set(stopwords.words('english'))
stop_words.update(['.', ',', '"', "'", '?', '!', ':', ';', '(', ')', '[', ']', '{', '}']) # remove it if you need punctuation 

for doc in documents:
    list_of_words = [i.lower() for i in wordpunct_tokenize(doc) if i.lower() not in stop_words]

Notice that due to the fact that here you are searching in a set (not in a list) the speed would be theoretically len(stop_words)/2 times faster, which is significant if you need to operate through many documents.

For 5000 documents of approximately 300 words each the difference is between 1.8 seconds for my example and 20 seconds for @alvas's.

P.S. in most of the cases you need to divide the text into words to perform some other classification tasks for which tf-idf is used. So most probably it would be better to use stemmer as well:

from nltk.stem.porter import PorterStemmer
porter = PorterStemmer()

and to use [porter.stem(i.lower()) for i in wordpunct_tokenize(doc) if i.lower() not in stop_words] inside of a loop.

Every answer seems to suggest that you need to use secure hashes to do the job but all of these are tuned to be slow to force a bruteforce attacker to have lots of computing power and depending on your needs this may not be the best solution.

There are algorithms specifically designed to hash files as fast as possible to check integrity and comparison (murmur, XXhash...). Obviously these are not designed for security as they don't meet the requirements of a secure hash algorithm (i.e. randomness) but have low collision rates for large messages. This features make them ideal if you are not looking for security but speed.

Examples of this algorithms and comparison can be found in this excellent answer: Which hashing algorithm is best for uniqueness and speed?.

As an example, we at our Q&A site use murmur3 to hash the images uploaded by the users so we only store them once even if users upload the same image in several answers.

It is because there is no default ROOT web application. When you create some web app and deploy it to Tomcat using Eclipse, then you will be able to access it with the URL in the form of

http://localhost:8080/YourWebAppName

where YourWebAppName is some name you give to your web app (the so called application context path).

Quote from Jetty Documentation Wiki (emphasis mine):

The context path is the prefix of a URL path that is used to select the web application to which an incoming request is routed. Typically a URL in a Java servlet server is of the format http://hostname.com/contextPath/servletPath/pathInfo, where each of the path elements may be zero or more / separated elements. If there is no context path, the context is referred to as the root context.

If you still want the default app which is accessed with the URL of the form

http://localhost:8080

or if you change the default 8080 port to 80, then just

http://localhost

i.e. without application context path read the following (quote from Tutorial: Installing Tomcat 7 and Using it with Eclipse, emphasis mine):

Copy the ROOT (default) Web app into Eclipse. Eclipse forgets to copy the default apps (ROOT, examples, docs, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.34\webapps and copy the ROOT folder. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like C:\your-eclipse-workspace-location\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or .../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.

<input type="text" id="input_id" />    

$('#input_id').keydown(function (event) {
    if (event.keyCode == 13) { 
         // Call your function here or add code here
    }
});

How about make clicking the a tag, to click on the file button?

There is more browser support for this, but I use ES6, so if you really want to make it work in older and any browser, try to transpile it using babel, or just simply use ES5:

const aTag = document.getElementById("open-file-uploader");_x000D_
const fileInput = document.getElementById("input-button");_x000D_
aTag.addEventListener("click", () => fileInput.click());

#input-button {_x000D_
  position: abosulte;_x000D_
  width: 1px;_x000D_
  height: 1px;_x000D_
  clip: rect(1px 1px 1px 1px);_x000D_
  clip: rect(1px, 1px, 1px, 1px);_x000D_
}

<a href="#" id="open-file-uploader">Open file uploader</a>_x000D_
<input type="file" id="input-button" />

That's a fun one. If you know ahead of time the height of the container of the text, you can use line-height equal to that height, and it should center the text vertically.

In Eclipse Ganymede (3.4.0):

1. Select the library and click "Edit" (left side of the window)
2. Click "User Libraries"
3. Select the library again and click "Add JARs"

Because constants in Ruby aren't meant to be changed, Ruby discourages you from assigning to them in parts of code which might get executed more than once, such as inside methods.

Under normal circumstances, you should define the constant inside the class itself:

class MyClass
  MY_CONSTANT = "foo"
end

MyClass::MY_CONSTANT #=> "foo"

If for some reason though you really do need to define a constant inside a method (perhaps for some type of metaprogramming), you can use const_set:

class MyClass
  def my_method
    self.class.const_set(:MY_CONSTANT, "foo")
  end
end

MyClass::MY_CONSTANT
#=> NameError: uninitialized constant MyClass::MY_CONSTANT

MyClass.new.my_method
MyClass::MY_CONSTANT #=> "foo"

Again though, const_set isn't something you should really have to resort to under normal circumstances. If you're not sure whether you really want to be assigning to constants this way, you may want to consider one of the following alternatives:

Class variables

Class variables behave like constants in many ways. They are properties on a class, and they are accessible in subclasses of the class they are defined on.

The difference is that class variables are meant to be modifiable, and can therefore be assigned to inside methods with no issue.

class MyClass
  def self.my_class_variable
    @@my_class_variable
  end
  def my_method
    @@my_class_variable = "foo"
  end
end
class SubClass < MyClass
end

MyClass.my_class_variable
#=> NameError: uninitialized class variable @@my_class_variable in MyClass
SubClass.my_class_variable
#=> NameError: uninitialized class variable @@my_class_variable in MyClass

MyClass.new.my_method
MyClass.my_class_variable #=> "foo"
SubClass.my_class_variable #=> "foo"

Class attributes

Class attributes are a sort of "instance variable on a class". They behave a bit like class variables, except that their values are not shared with subclasses.

class MyClass
  class << self
    attr_accessor :my_class_attribute
  end
  def my_method
    self.class.my_class_attribute = "blah"
  end
end
class SubClass < MyClass
end

MyClass.my_class_attribute #=> nil
SubClass.my_class_attribute #=> nil

MyClass.new.my_method
MyClass.my_class_attribute #=> "blah"
SubClass.my_class_attribute #=> nil

SubClass.new.my_method
SubClass.my_class_attribute #=> "blah"

Instance variables

And just for completeness I should probably mention: if you need to assign a value which can only be determined after your class has been instantiated, there's a good chance you might actually be looking for a plain old instance variable.

class MyClass
  attr_accessor :instance_variable
  def my_method
    @instance_variable = "blah"
  end
end

my_object = MyClass.new
my_object.instance_variable #=> nil
my_object.my_method
my_object.instance_variable #=> "blah"

MyClass.new.instance_variable #=> nil

For others having the same problem, try running

git add . which will add all files of the current directory to track (including untracked) and then use

git commit -a to commit all tracked files.

As suggested by @Pacerier, one liner that does the same thing is

git add -A

Never, ever try to write the R class yourself!

Have you imported the right R class in your files?

Doing

import android.R;

instead of

import com.example.R;

seems to be the problem for a lot of people. After cleaning and building, my classes sometimes import the wrong one.

Unfortunately, it seems that pm2 doesn't support the exact functionality you requested https://github.com/Unitech/PM2/issues/1317.

The alternative proposed is to use a ecosystem.json file Getting started with deployment which could include setups for production and dev environments. However, this is still using npm start to bootstrap your app.

Many of the answers here are out of date for 2015 (although the initially accepted one from Daniel Roseman is not). Here's the current state of things:

• Binary packages are now distributed as wheels (.whl files)—not just on PyPI, but in third-party repositories like Christoph Gohlke's Extension Packages for Windows. pip can handle wheels; easy_install cannot.
• Virtual environments (which come built-in with 3.4, or can be added to 2.6+/3.1+ with virtualenv) have become a very important and prominent tool (and recommended in the official docs); they include pip out of the box, but don't even work properly with easy_install.
• The distribute package that included easy_install is no longer maintained. Its improvements over setuptools got merged back into setuptools. Trying to install distribute will just install setuptools instead.
• easy_install itself is only quasi-maintained.
• All of the cases where pip used to be inferior to easy_install—installing from an unpacked source tree, from a DVCS repo, etc.—are long-gone; you can pip install ., pip install git+https://.
• pip comes with the official Python 2.7 and 3.4+ packages from python.org, and a pip bootstrap is included by default if you build from source.
• The various incomplete bits of documentation on installing, using, and building packages have been replaced by the Python Packaging User Guide. Python's own documentation on Installing Python Modules now defers to this user guide, and explicitly calls out pip as "the preferred installer program".
• Other new features have been added to pip over the years that will never be in easy_install. For example, pip makes it easy to clone your site-packages by building a requirements file and then installing it with a single command on each side. Or to convert your requirements file to a local repo to use for in-house development. And so on.

The only good reason that I know of to use easy_install in 2015 is the special case of using Apple's pre-installed Python versions with OS X 10.5-10.8. Since 10.5, Apple has included easy_install, but as of 10.10 they still don't include pip. With 10.9+, you should still just use get-pip.py, but for 10.5-10.8, this has some problems, so it's easier to sudo easy_install pip. (In general, easy_install pip is a bad idea; it's only for OS X 10.5-10.8 that you want to do this.) Also, 10.5-10.8 include readline in a way that easy_install knows how to kludge around but pip doesn't, so you also want to sudo easy_install readline if you want to upgrade that.

Below settings are worked well for me,

"editor.insertSpaces": false,
"editor.formatOnSave": true, // only if you want auto fomattting on saving the file
"editor.detectIndentation": false

Above settings will reflect and applied to every files. You don't need to indent/format every file manually.

An easy way without using collections

public void findHighestNoInArray() {
        int[] a = {1,2,6,8,9};
        int large = a[0];
            for(int num : a) {
                if(large < num) {
                    large = num;
                }
            }
            System.out.println("Large number is "+large+"");
        }

Kate, the KDE Advanced Text Editor is quite good. It has syntax highlighting, block selection mode, terminal/console, sessions, window splitting both horizontal and vertical etc.

Does this do what you want?

print range(0, (m+1)*n, n)[1:]

For m=5, n=20

[20, 40, 60, 80, 100]

Or better yet,

>>> print range(n, (m+1)*n, n)
[20, 40, 60, 80, 100] 

For Python3+

>>> print(list(range(n, (m+1)*n, n)))
[20, 40, 60, 80, 100] 

Instead of the modulo operator, which has slightly different semantics, for non-negative integers, you can use the remainder operator %. For your exact example:

if ((a % 2) == 0)
{
    isEven = true;
}
else
{
    isEven = false;
}

This can be simplified to a one-liner:

isEven = (a % 2) == 0;

You could use

Calendar cal = Calendar.getInstance();
cal.setTime(beginupd);
long millis = cal.getTimeInMillis();

It's very simple to define a function inside razor.

@functions {

    public static HtmlString OrderedList(IEnumerable<string> items)
    { }
}

So you can call a the function anywhere. Like

@Functions.OrderedList(new[] { "Blue", "Red", "Green" })

However, this same work can be done through helper too. As an example

@helper OrderedList(IEnumerable<string> items){
    <ol>
        @foreach(var item in items){
            <li>@item</li>
        }
    </ol>
}

So what is the difference?? According to this previous post both @helpers and @functions do share one thing in common - they make code reuse a possibility within Web Pages. They also share another thing in common - they look the same at first glance, which is what might cause a bit of confusion about their roles. However, they are not the same. In essence, a helper is a reusable snippet of Razor sytnax exposed as a method, and is intended for rendering HTML to the browser, whereas a function is static utility method that can be called from anywhere within your Web Pages application. The return type for a helper is always HelperResult, whereas the return type for a function is whatever you want it to be.

Below line will randomly select n number of rows out of the total existing row numbers from the dataframe df without replacement.

df=df.take(np.random.permutation(len(df))[:n])

Be careful with dimensions.

Let

x  # initial numpy array
I = np.argsort(x) or I = x.argsort() 
y = np.sort(x)    or y = x.sort()
z  # reverse sorted array

Full Reverse

z = x[I[::-1]]
z = -np.sort(-x)
z = np.flip(y)

• flip changed in 1.15, previous versions 1.14 required axis. Solution: pip install --upgrade numpy.

First Dimension Reversed

z = y[::-1]
z = np.flipud(y)
z = np.flip(y, axis=0)

Second Dimension Reversed

z = y[::-1, :]
z = np.fliplr(y)
z = np.flip(y, axis=1)

Testing

Testing on a 100×10×10 array 1000 times.

Method       | Time (ms)
-------------+----------
y[::-1]      | 0.126659  # only in first dimension
-np.sort(-x) | 0.133152
np.flip(y)   | 0.121711
x[I[::-1]]   | 4.611778

x.sort()     | 0.024961
x.argsort()  | 0.041830
np.flip(x)   | 0.002026

This is mainly due to reindexing rather than argsort.

# Timing code
import time
import numpy as np


def timeit(fun, xs):
    t = time.time()
    for i in range(len(xs)):  # inline and map gave much worse results for x[-I], 5*t
        fun(xs[i])
    t = time.time() - t
    print(np.round(t,6))

I, N = 1000, (100, 10, 10)
xs = np.random.rand(I,*N)
timeit(lambda x: np.sort(x)[::-1], xs)
timeit(lambda x: -np.sort(-x), xs)
timeit(lambda x: np.flip(x.sort()), xs)

curl's -w option and the sub variable url_effective is what you are looking for.

Something like

curl -Ls -o /dev/null -w %{url_effective} http://google.com

More info

-L         Follow redirects
-s         Silent mode. Don't output anything
-o FILE    Write output to <file> instead of stdout
-w FORMAT  What to output after completion

You might want to add -I (that is an uppercase i) as well, which will make the command not download any "body", but it then also uses the HEAD method, which is not what the question included and risk changing what the server does. Sometimes servers don't respond well to HEAD even when they respond fine to GET.

The :: operator is called the scope-resolution operator and does just that, it resolves scope. So, by prefixing a type-name with this, it tells your compiler to look in the global namespace for the type.

Example:

int count = 0;

int main(void) {
  int count = 0;
  ::count = 1;  // set global count to 1
  count = 2;    // set local count to 2
  return 0;
}

VBScript's While loops don't support early exit. Use the Do loop for that:

num = 0
do while (num < 10)
  if (status = "Fail") then exit do
  num = num + 1
loop

 LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.text_entry, null);

final EditText input2 = (EditText) textEntryView.findViewById(R.id.EditText2);             
input1.setText("DefaultValue", TextView.BufferType.EDITABLE);
input2.setText("DefaultValue", TextView.BufferType.EDITABLE);

         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int whichButton) {

Overriding navigationBar(_ navigationBar:shouldPop): This is not a good idea, even if it works. for me it generated random crashes on navigating back. I advise you to just override the back button by removing the default backButton from navigationItem and creating a custom back button like below:

override func viewDidLoad(){
   super.viewDidLoad()
   
   navigationItem.leftBarButton = .init(title: "Go Back", ... , action: #selector(myCutsomBackAction) 

   ...
 
}

========================================

Building on previous responses with UIAlert in Swift5 in a Asynchronous way

protocol NavigationControllerBackButtonDelegate {
    func shouldPopOnBackButtonPress(_ completion: @escaping (Bool) -> ())
}

extension UINavigationController: UINavigationBarDelegate {
    public func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
      
        if viewControllers.count < navigationBar.items!.count {
            return true
        }
        
        // Check if we have a view controller that wants to respond to being popped
        
        if let viewController = topViewController as? NavigationControllerBackButtonDelegate {
            
            viewController.shouldPopOnBackButtonPress { shouldPop in
                if (shouldPop) {
                    /// on confirm => pop
                    DispatchQueue.main.async {
                        self.popViewController(animated: true)
                    }
                } else {
                    /// on cancel => do nothing
                }
            }
            /// return false => so navigator will cancel the popBack
            /// until user confirm or cancel
            return false
        }else{
            DispatchQueue.main.async {
                self.popViewController(animated: true)
            }
        }
        return true
    }
}

On your controller

extension MyController: NavigationControllerBackButtonDelegate {
    
    func shouldPopOnBackButtonPress(_ completion: @escaping (Bool) -> ()) {
    
        let msg = "message"
        
        /// show UIAlert
        alertAttention(msg: msg, actions: [
            
            .init(title: "Continuer", style: .destructive, handler: { _ in
                completion(true)
            }),
            .init(title: "Annuler", style: .cancel, handler: { _ in
                completion(false)
            })
            ])
   
    }

}

Try this:

var keys = [];
for (var key in dictionary) {
  if (dictionary.hasOwnProperty(key)) {
    keys.push(key);
  }
}

hasOwnProperty is needed because it's possible to insert keys into the prototype object of dictionary. But you typically don't want those keys included in your list.

For example, if you do this:

Object.prototype.c = 3;
var dictionary = {a: 1, b: 2};

and then do a for...in loop over dictionary, you'll get a and b, but you'll also get c.

String y = "hello";

would work (note the double quotes).

char y = 'h'; this will work for chars (note the single quotes)

but the type is the key: '' (single quotes) for one char, "" (double quotes) for string.

You must use the column names and then set the values to insert (both ? marks):

//insert 1st row            
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();

Sounds like a homework problem. scanf() is the wrong function to use for the problem. I'd recommend getchar() or getch().

Note: I'm purposefully not solving the problem since this seems like homework, instead just pointing you in the right direction.

A short solution using map and an arrow function

var data = [{_x000D_
  "id": "1",_x000D_
  "msg": "hi",_x000D_
  "tid": "2013-05-05 23:35",_x000D_
  "fromWho": "[email protected]"_x000D_
}, {_x000D_
  "id": "2",_x000D_
  "msg": "there",_x000D_
  "tid": "2013-05-05 23:45",_x000D_
  "fromWho": "[email protected]"_x000D_
}];_x000D_
data.map((item, i) => console.log('Index:', i, 'Id:', item.id));

And to cover the cases when the property "id" is not present use filter:

var data = [{_x000D_
  "id": "1",_x000D_
  "msg": "hi",_x000D_
  "tid": "2013-05-05 23:35",_x000D_
  "fromWho": "[email protected]"_x000D_
}, {_x000D_
  "id": "2",_x000D_
  "msg": "there",_x000D_
  "tid": "2013-05-05 23:45",_x000D_
  "fromWho": "[email protected]"_x000D_
}, {_x000D_
  "msg": "abcde",_x000D_
  "tid": "2013-06-06 23:46",_x000D_
  "fromWho": "[email protected]"_x000D_
}];_x000D_
_x000D_
data.filter(item=>item.hasOwnProperty('id'))_x000D_
                .map((item, i) => console.log('Index:', i, 'Id:', item.id));
