ffmpeg logs to stderr, and can log to a file with a different log-level from stderr. The -report command-line option doesn't give you control of the log file name or the log level, so setting the environment variable is preferable.

(-v is a synonym for -loglevel. Run ffmpeg -v help to see the levels. Run ffmpeg -h full | less to see EVERYTHING. Or consult the online docs, or their wiki pages like the h.264 encode guide).

#!/bin/bash

of=out.mkv
FFREPORT="level=32:file=$of.log" ffmpeg -v verbose   -i src.mp4 -c:a copy -preset slower -c:v libx264 -crf 21 "$of"

That will trancode src.mp4 with x264, and set the log level for stderr to "verbose", and the log level for out.mkv.log to "status".

(AV_LOG_WARNING=24, AV_LOG_INFO=32, AV_LOG_VERBOSE=40, etc.). Support for this was added 2 years ago, so you need a non-ancient version of ffmpeg. (Always a good idea anyway, for security / bugfixes and speedups)

A few codecs, like -c:v libx265, write directly to stderr instead of using ffmpeg's logging infrastructure. So their log messages don't end up in the report file. I assume this is a bug / TODO-list item.

To log stderr, while still seeing it in a terminal, you can use tee(1).

If you use a log level that includes status line updates (the default -v info, or higher), they will be included in the log file, separated with ^M (carriage return aka \r). There's no log level that includes encoder stats (like SSIM) but not status-line updates, so the best option is probably to filter that stream.

If don't want to filter (e.g. so the fps / bitrate at each status-update interval is there in the file), you can use less -r to pass them through directly to your terminal so you can view the files cleanly. If you have .enc logs from several encodes that you want to flip through, less -r ++G *.enc works great. (++G means start at the end of the file, for all files). With single-key key bindings like . and , for next file and previous file, you can flip through some log files very nicely. (the default bindings are :n and :p).

If you do want to filter, sed 's/.*\r//' works perfectly for ffmpeg output. (In the general case, you need something like vt100.py, but not for just carriage returns). There are (at least) two ways to do this with tee + sed: tee to /dev/tty and pipe tee's output into sed, or use a process substitution to tee into a pipe to sed.

# pass stdout and stderr through to the terminal, 
## and log a filtered version to a file (with only the last status-line update).

of="$1-x265.mkv"
ffmpeg -v info -i "$1" -c:a copy -c:v libx265 ... "$of" |&    # pipe stdout and stderr
   tee /dev/tty | sed 's/.*\r//' >> "$of.enc"

## or with process substitution where tee's arg will be something like /dev/fd/123

ffmpeg -v info -i "$1" -c:a copy -c:v libx265 ... "$of" |&
  tee >(sed 's/.*\r//' >> "$of.enc")

For testing a few different encode parameters, you can make a function like this one that I used recently to test some stuff. I had it all on one line so I could easily up-arrow and edit it, but I'll un-obfuscate it here. (That's why there are ;s at the end of each line)

ffenc-testclip(){
  # v should be set by the caller, to a vertical resolution.  We scale to WxH, where W is a multiple of 8 (-vf scale=-8:$v)
  db=0;   # convenient to use shell vars to encode settings that you want to include in the filename and the ffmpeg cmdline
  [email protected].${v}p.x265$pre.mkv; 
  [[ -e "$of.enc" ]]&&echo "$of.enc exists"&&return;   # early-out if the file exists

  # encode 25 seconds starting at 21m15s (or the keyframe before that)
  nice -14 ffmpeg -ss $((21*60+15))  -i src.mp4 -t 25  -map 0 -metadata title= -color_primaries bt709 -color_trc bt709 -colorspace bt709 -sws_flags lanczos+print_info -c:a copy -c:v libx265 -b:v 1500k -vf scale=-8:$v  -preset $pre -ssim 1 -x265-params ssim=1:cu-stats=1:deblock=$db:aq-mode=1:lookahead-slices=0 "$of" |&
   tee /dev/tty | sed 's/.*\r//' >> "$of.enc";
}

# and use it with nested loops like this.
for pre in fast slow;  do for v in  360 480 648 792;do  ffenc-testclip ;done;done

less -r ++G *.enc       # -r is useful if you didn't use sed

Note that it tests for existence of the output video file to avoid spewing extra garbage into the log file if it already exists. Even so, I used and append (>>) redirect.

It would be "cleaner" to write a shell function that took args instead of looking at shell variables, but this was convenient and easy to write for my own use. That's also why I saved space by not properly quoting all my variable expansions. ($v instead of "$v")

A python string is a list of characters. You can iterate over it right now!

justdigits = ""
for char in string:
    if char.isdigit():
        justdigits += str(char)

Update 3: As other answers point out as well, the npm ci command got introduced in npm 5.7.0 as additional way to achieve fast and reproducible builds in the CI context. See the documentation and npm blog for further information.

Update 2: The issue to update and clarify the documentation is GitHub issue #18103.

Update 1: The behaviour that was described below got fixed in npm 5.4.2: the currently intended behaviour is outlined in GitHub issue #17979.

Original answer: The behaviour of package-lock.json was changed in npm 5.1.0 as discussed in issue #16866. The behaviour that you observe is apparently intended by npm as of version 5.1.0.

That means that package.json can override package-lock.json whenever a newer version is found for a dependency in package.json. If you want to pin your dependencies effectively, you now must specify the versions without a prefix, e.g., you need to write them as 1.2.0 instead of ~1.2.0 or ^1.2.0. Then the combination of package.json and package-lock.json will yield reproducible builds. To be clear: package-lock.json alone no longer locks the root level dependencies!

Whether this design decision was good or not is arguable, there is an ongoing discussion resulting from this confusion on GitHub in issue #17979. (In my eyes it is a questionable decision; at least the name lock doesn't hold true any longer.)

One more side note: there is also a restriction for registries that don’t support immutable packages, such as when you pull packages directly from GitHub instead of npmjs.org. See this documentation of package locks for further explanation.

What about this solution? It does not rely on knowledge of @staticmethod decorator implementation. Inner class StaticMethod plays as a container of static initialization functions.

class Klass(object):

    class StaticMethod:
        @staticmethod  # use as decorator
        def _stat_func():
            return 42

    _ANS = StaticMethod._stat_func()  # call the staticmethod

    def method(self):
        ret = self.StaticMethod._stat_func() + Klass._ANS
        return ret

If the error message is just

"Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.", then grant the login permission for 'NT AUTHORITY\NETWORK SERVICE'

by using

"sp_grantlogin 'NT AUTHORITY\NETWORK SERVICE'" 

else if the error message is like

"Cannot open database "Phaeton.mdf" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'."

try using

"EXEC sp_grantdbaccess 'NT AUTHORITY\NETWORK SERVICE'" 

under your "Phaeton" database.

In case you have multiple images and you want to loop though them and show them 1 by 1 along with titles - this is what you can do. No need to explicitly define ax1, ax2, etc.

1. The catch is you can define dynamic axes(ax) as in Line 1 of code and you can set its title inside a loop.
2. The rows of 2D array is length (len) of axis(ax)
3. Each row has 2 items i.e. It is list within a list (Point No.2)
4. set_title can be used to set title, once the proper axes(ax) or subplot is selected.

import matplotlib.pyplot as plt    
fig, ax = plt.subplots(2, 2, figsize=(6, 8))  
for i in range(len(ax)): 
    for j in range(len(ax[i])):
        ## ax[i,j].imshow(test_images_gr[0].reshape(28,28))
        ax[i,j].set_title('Title-' + str(i) + str(j))

The short answer is that setting grid-auto-rows: 1fr; on the grid container solves what was asked.

You're referencing a DOM element when doing something like $('#lastName'). That's an element with id attribute "lastName". Why do that? You want to reference the value stored in a local variable, completely unrelated. Try this (assuming the assignment to formObject is in the same scope as the variable declarations) -

var formObject = {
    formObject: [
        {
            firstName:firstName,  // no need to quote variable names
            lastName:lastName
        },
        {
            phoneNumber:phoneNumber,
            address:address
        }
    ]
};

This seems very odd though: you're creating an object "formObject" that contains a member called "formObject" that contains an array of objects.

to remove the height:

$('div#someDiv').css('height', '');
$('div#someDiv').css('height', null);

like John pointed out, set height to auto:

$('div#someDiv').css('height', 'auto');

I believe you need to create a file called __init__.py in the Models directory so that python treats it as a module.

Then you can do:

from Models.user import User

You can include code in the __init__.py (for instance initialization code that a few different classes need) or leave it blank. But it must be there.

This can be done using an attribute selector.

[class~='list']:last-of-type  {
    background: #000;
}

The class~ selects a specific whole word. This allows your list item to have multiple classes if need be, in various order. It'll still find the exact class "list" and apply the style to the last one.

See a working example here: http://codepen.io/chasebank/pen/ZYyeab

Here is a list of commercial vendors that provide off-the-shelf packages for facial recognition which run on Windows:

1. Cybula - Information on their Facial Recognition SDK. This is a company founded by a University Professor and as such their website looks unprofessional. There's no pricing information or demo that you can download. You'll need to contact them for pricing information.

2. NeuroTechnology - Information on their Facial Recognition SDK. This company has both up-front pricing information as well as an actual 30 day trial of their SDK.

3. Pittsburgh Pattern Recognition - (Acquired by Google) Information on their Facial Tracking and Recognition SDK. The demos that they provide help you evaluate their technology but not their SDSK. You'll need to contact them for pricing information.

4. Sensible Vision - Information on their SDK. Their site allows you to easily get a price quote and you can also order an evaluation kit that will help you evaluate their technology.

You want to do the check for undefined first. If you do it the other way round, it will generate an error if the array is undefined.

if (array === undefined || array.length == 0) {
    // array empty or does not exist
}

Update

This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null values, other types of objects with a length property, etc. It is also not very idiomatic JavaScript.

The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length property.

if (!Array.isArray(array) || !array.length) {
  // array does not exist, is not an array, or is empty
  // ? do not attempt to process array
}

To break it down:

1. Array.isArray(), unsurprisingly, checks whether its argument is an array. This weeds out values like null, undefined and anything else that is not an array.
   Note that this will also eliminate array-like objects, such as the arguments object and DOM NodeList objects. Depending on your situation, this might not be the behavior you're after.

2. The array.length condition checks whether the variable's length property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0 or array.length !== 0 are not required here.

The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.

In those cases, I tend to go for the following, more idiomatic JavaScript:

if (!array || !array.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or, more frequently, its inverse:

if (array && array.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:

if (!array?.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or the opposite:

if (array?.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

This solution is simple, elegant and works in all browsers:

var video = $("#playerid").attr("src");
$("#playerid").attr("src","");
$("#playerid").attr("src",video);

As an enhancement to @Corey Hart's answer, I've rewritten the parseCookies() using:

• RegExp.prototype.exec - use regex to parse "name=value" strings

Here's the working example:

let http = require('http');

function parseCookies(str) {
  let rx = /([^;=\s]*)=([^;]*)/g;
  let obj = { };
  for ( let m ; m = rx.exec(str) ; )
    obj[ m[1] ] = decodeURIComponent( m[2] );
  return obj;
}

function stringifyCookies(cookies) {
  return Object.entries( cookies )
    .map( ([k,v]) => k + '=' + encodeURIComponent(v) )
    .join( '; ');
}

http.createServer(function ( request, response ) {
  let cookies = parseCookies( request.headers.cookie );
  console.log( 'Input cookies: ', cookies );
  cookies.search = 'google';
  if ( cookies.counter )
    cookies.counter++;
  else
    cookies.counter = 1;
  console.log( 'Output cookies: ', cookies );
  response.writeHead( 200, {
    'Set-Cookie': stringifyCookies(cookies),
    'Content-Type': 'text/plain'
  } );
  response.end('Hello World\n');
} ).listen(1234);

I also note that the OP uses the http module. If the OP was using restify, he can make use of restify-cookies:

var CookieParser = require('restify-cookies');
var Restify = require('restify');
var server = Restify.createServer();
server.use(CookieParser.parse);
server.get('/', function(req, res, next){
  var cookies = req.cookies; // Gets read-only cookies from the request
  res.setCookie('my-new-cookie', 'Hi There'); // Adds a new cookie to the response
  res.send(JSON.stringify(cookies));
});
server.listen(8080);

std::map<Key, Value> ? SortedDictionary<TKey, TValue>

std::unordered_map<Key, Value> ? Dictionary<TKey, TValue>

If you're looking for a way to create a list by looping through a JSON array of your images and descriptions for example, this will work for you.

1. Create a file (to hold our JSON database) e.g ProfilesDB.js:

const Profiles=[_x000D_
   {_x000D_
   "id" : "1",_x000D_
   "name" : "Peter Parker",_x000D_
   "src" : require('../images/user1.png'),_x000D_
   "age":"70",_x000D_
 },_x000D_
 {_x000D_
 "id" : "2",_x000D_
 "name" : "Barack Obama",_x000D_
 "src" : require('../images/user2.png'),_x000D_
 "age":"19",_x000D_
 },_x000D_
 {_x000D_
 "id" : "3",_x000D_
 "name" : "Hilary Clinton",_x000D_
 "src" : require('../images/user3.png'),_x000D_
 "age":"50",_x000D_
 }_x000D_
]_x000D_
export default Profiles;

2. Then import the data in our component and loop through the list using a FlatList:

import Profiles from './ProfilesDB.js';_x000D_
_x000D_
<FlatList_x000D_
  data={Profiles}_x000D_
  keyExtractor={(item, index) => item.id}_x000D_
  renderItem={({item}) => (_x000D_
    <View>_x000D_
      <Image source={item.src} />_x000D_
      <Text>{item.name}</Text>_x000D_
    </View>_x000D_
  )}_x000D_
/>

Good luck!

Get rid of the values keyword and the parens. You can see an example here.

This is basic INSERT syntax:

INSERT INTO "table_name" ("column1", "column2", ...)
VALUES ("value1", "value2", ...);

This is the INSERT SELECT syntax:

INSERT INTO "table1" ("column1", "column2", ...)
SELECT "column3", "column4", ...
FROM "table2";

The following is a proposed solution for the OP's specific problem (extracting the 2nd word of a string), but it should be noted that, as mc0e's answer states, actually extracting regex matches is not supported out-of-the-box in MySQL. If you really need this, then your choices are basically to 1) do it in post-processing on the client, or 2) install a MySQL extension to support it.

BenWells has it very almost correct. Working from his code, here's a slightly adjusted version:

SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
)

As a working example, I used:

SELECT SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
) as string
FROM (SELECT 'THIS IS A TEST' AS sentence) temp

This successfully extracts the word IS

In my opinion, to answer this question, you need to think in terms of project life cycle and version control. In other words, does the parent pom have its own life cycle i.e. can it be released separately of the other modules or not?

If the answer is yes (and this is the case of most projects that have been mentioned in the question or in comments), then the parent pom needs his own module from a VCS and from a Maven point of view and you'll end up with something like this at the VCS level:

root
|-- parent-pom
|   |-- branches
|   |-- tags
|   `-- trunk
|       `-- pom.xml
`-- projectA
    |-- branches
    |-- tags
    `-- trunk
        |-- module1
        |   `-- pom.xml
        |-- moduleN
        |   `-- pom.xml
        `-- pom.xml

This makes the checkout a bit painful and a common way to deal with that is to use svn:externals. For example, add a trunks directory:

root
|-- parent-pom
|   |-- branches
|   |-- tags
|   `-- trunk
|       `-- pom.xml
|-- projectA
|   |-- branches
|   |-- tags
|   `-- trunk
|       |-- module1
|       |   `-- pom.xml
|       |-- moduleN
|       |   `-- pom.xml
|       `-- pom.xml
`-- trunks

With the following externals definition:

parent-pom http://host/svn/parent-pom/trunk
projectA http://host/svn/projectA/trunk

A checkout of trunks would then result in the following local structure (pattern #2):

root/
  parent-pom/
    pom.xml
  projectA/

Optionally, you can even add a pom.xml in the trunks directory:

root
|-- parent-pom
|   |-- branches
|   |-- tags
|   `-- trunk
|       `-- pom.xml
|-- projectA
|   |-- branches
|   |-- tags
|   `-- trunk
|       |-- module1
|       |   `-- pom.xml
|       |-- moduleN
|       |   `-- pom.xml
|       `-- pom.xml
`-- trunks
    `-- pom.xml

This pom.xml is a kind of "fake" pom: it is never released, it doesn't contain a real version since this file is never released, it only contains a list of modules. With this file, a checkout would result in this structure (pattern #3):

root/
  parent-pom/
    pom.xml
  projectA/
  pom.xml

This "hack" allows to launch of a reactor build from the root after a checkout and make things even more handy. Actually, this is how I like to setup maven projects and a VCS repository for large builds: it just works, it scales well, it gives all the flexibility you may need.

If the answer is no (back to the initial question), then I think you can live with pattern #1 (do the simplest thing that could possibly work).

Now, about the bonus questions:

• Where is the best place to define the various shared configuration as in source control, deployment directories, common plugins etc. (I'm assuming the parent but I've often been bitten by this and they've ended up in each project rather than a common one).

Honestly, I don't know how to not give a general answer here (like "use the level at which you think it makes sense to mutualize things"). And anyway, child poms can always override inherited settings.

• How do the maven-release plugin, hudson and nexus deal with how you set up your multi-projects (possibly a giant question, it's more if anyone has been caught out when by how a multi-project build has been set up)?

The setup I use works well, nothing particular to mention.

Actually, I wonder how the maven-release-plugin deals with pattern #1 (especially with the <parent> section since you can't have SNAPSHOT dependencies at release time). This sounds like a chicken or egg problem but I just can't remember if it works and was too lazy to test it.

(This is already answered in comments, but since it lacks an actual answer, I'm writing this.)

This problem arises in newer versions of Visual C++ (the older versions usually just silently linked the program and it would crash and burn at run time.) It means that some of the libraries you are linking with your program (or even some of the source files inside your program itself) are using different versions of the CRT (the C RunTime library.)

To correct this error, you need to go into your Project Properties (and/or those of the libraries you are using,) then into C/C++, then Code Generation, and check the value of Runtime Library; this should be exactly the same for all the files and libraries you are linking together. (The rules are a little more relaxed for linking with DLLs, but I'm not going to go into the "why" and into more details here.)

There are currently four options for this setting:

1. Multithreaded Debug
2. Multithreaded Debug DLL
3. Multithreaded Release
4. Multithreaded Release DLL

Your particular problem seems to stem from you linking a library built with "Multithreaded Debug" (i.e. static multithreaded debug CRT) against a program that is being built using the "Multithreaded Debug DLL" setting (i.e. dynamic multithreaded debug CRT.) You should change this setting either in the library, or in your program. For now, I suggest changing this in your program.

Note that since Visual Studio projects use different sets of project settings for debug and release builds (and 32/64-bit builds) you should make sure the settings match in all of these project configurations.

For (some) more information, you can see these (linked from a comment above):

1. Linker Tools Warning LNK4098 on MSDN
2. /MD, /ML, /MT, /LD (Use Run-Time Library) on MSDN
3. Build errors with VC11 Beta - mixing MTd libs with MDd exes fail to link on Bugzilla@Mozilla

UPDATE: (This is in response to a comment that asks for the reason that this much care must be taken.)

If two pieces of code that we are linking together are themselves linking against and using the standard library, then the standard library must be the same for both of them, unless great care is taken about how our two code pieces interact and pass around data. Generally, I would say that for almost all situations just use the exact same version of the standard library runtime (regarding debug/release, threads, and obviously the version of Visual C++, among other things like iterator debugging, etc.)

The most important part of the problem is this: having the same idea about the size of objects on either side of a function call.

Consider for example that the above two pieces of code are called A and B. A is compiled against one version of the standard library, and B against another. In A's view, some random object that a standard function returns to it (e.g. a block of memory or an iterator or a FILE object or whatever) has some specific size and layout (remember that structure layout is determined and fixed at compile time in C/C++.) For any of several reasons, B's idea of the size/layout of the same objects is different (it can be because of additional debug information, natural evolution of data structures over time, etc.)

Now, if A calls the standard library and gets an object back, then passes that object to B, and B touches that object in any way, chances are that B will mess that object up (e.g. write the wrong field, or past the end of it, etc.)

The above isn't the only kind of problems that can happen. Internal global or static objects in the standard library can cause problems too. And there are more obscure classes of problems as well.

All this gets weirder in some aspects when using DLLs (dynamic runtime library) instead of libs (static runtime library.)

This situation can apply to any library used by two pieces of code that work together, but the standard library gets used by most (if not almost all) programs, and that increases the chances of clash.

What I've described is obviously a watered down and simplified version of the actual mess that awaits you if you mix library versions. I hope that it gives you an idea of why you shouldn't do it!

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

onDestroy() is meant for final cleanup - freeing up resources that you can on your own,closing open connections,readers,writers,etc. If you don't override it, the system does what it has to.

on the other hand, finish() just lets the system know that the programmer wants the current Activity to be finished. And hence, it calls up onDestroy() after that.

Something to note:

it isn't necessary that only a call to finish() triggers a call to onDestroy(). No. As we know, the android system is free to kill activities if it feels that there are resources needed by the current Activity that are needed to be freed.

From what I learned after several days of research, Here is the Guide for ASP .Net Core MVC 2.x Custom User Authentication

In Startup.cs :

Add below lines to ConfigureServices method :

public void ConfigureServices(IServiceCollection services)
{

services.AddAuthentication(
    CookieAuthenticationDefaults.AuthenticationScheme
).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
    options =>
    {
        options.LoginPath = "/Account/Login";
        options.LogoutPath = "/Account/Logout";
    });

    services.AddMvc();

    // authentication 
    services.AddAuthentication(options =>
    {
       options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    });

    services.AddTransient(
        m => new UserManager(
            Configuration
                .GetValue<string>(
                    DEFAULT_CONNECTIONSTRING //this is a string constant
                )
            )
        );
     services.AddDistributedMemoryCache();
}

keep in mind that in above code we said that if any unauthenticated user requests an action which is annotated with [Authorize] , they well force redirect to /Account/Login url.

Add below lines to Configure method :

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler(ERROR_URL);
    }
     app.UseStaticFiles();
     app.UseAuthentication();
     app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: DEFAULT_ROUTING);
    });
}

Create your UserManager class that will also manage login and logout. it should look like below snippet (note that i'm using dapper):

public class UserManager
{
    string _connectionString;

    public UserManager(string connectionString)
    {
        _connectionString = connectionString;
    }

    public async void SignIn(HttpContext httpContext, UserDbModel user, bool isPersistent = false)
    {
        using (var con = new SqlConnection(_connectionString))
        {
            var queryString = "sp_user_login";
            var dbUserData = con.Query<UserDbModel>(
                queryString,
                new
                {
                    UserEmail = user.UserEmail,
                    UserPassword = user.UserPassword,
                    UserCellphone = user.UserCellphone
                },
                commandType: CommandType.StoredProcedure
            ).FirstOrDefault();

            ClaimsIdentity identity = new ClaimsIdentity(this.GetUserClaims(dbUserData), CookieAuthenticationDefaults.AuthenticationScheme);
            ClaimsPrincipal principal = new ClaimsPrincipal(identity);

            await httpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
        }
    }

    public async void SignOut(HttpContext httpContext)
    {
        await httpContext.SignOutAsync();
    }

    private IEnumerable<Claim> GetUserClaims(UserDbModel user)
    {
        List<Claim> claims = new List<Claim>();

        claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
        claims.Add(new Claim(ClaimTypes.Name, user.UserFirstName));
        claims.Add(new Claim(ClaimTypes.Email, user.UserEmail));
        claims.AddRange(this.GetUserRoleClaims(user));
        return claims;
    }

    private IEnumerable<Claim> GetUserRoleClaims(UserDbModel user)
    {
        List<Claim> claims = new List<Claim>();

        claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
        claims.Add(new Claim(ClaimTypes.Role, user.UserPermissionType.ToString()));
        return claims;
    }
}

Then maybe you have an AccountController which has a Login Action that should look like below :

public class AccountController : Controller
{
    UserManager _userManager;

    public AccountController(UserManager userManager)
    {
        _userManager = userManager;
    }

    [HttpPost]
    public IActionResult LogIn(LogInViewModel form)
    {
        if (!ModelState.IsValid)
            return View(form);
         try
        {
            //authenticate
            var user = new UserDbModel()
            {
                UserEmail = form.Email,
                UserCellphone = form.Cellphone,
                UserPassword = form.Password
            };
            _userManager.SignIn(this.HttpContext, user);
             return RedirectToAction("Search", "Home", null);
         }
         catch (Exception ex)
         {
            ModelState.AddModelError("summary", ex.Message);
            return View(form);
         }
    }
}

Now you are able to use [Authorize] annotation on any Action or Controller.

Feel free to comment any questions or bug's.

Old thread I know.......

Problem with the answer of @ryuutatsuo is that it blocks also any input or other element that has to react on 'clicks' (for example inputs), so i wrote this solution. This solution made it possible to use any existing drag and drop library that is based upon mousedown, mousemove and mouseup events on any touch device (or cumputer). This is also a cross-browser solution.

I have tested in on several devices and it works fast (in combination with the drag and drop feature of ThreeDubMedia (see also http://threedubmedia.com/code/event/drag)). It is a jQuery solution so you can use it only with jQuery libs. I have used jQuery 1.5.1 for it because some newer functions don't work properly with IE9 and above (not tested with newer versions of jQuery).

Before you add any drag or drop operation to an event you have to call this function first:

simulateTouchEvents(<object>);

You can also block all components/children for input or to speed up event handling by using the following syntax:

simulateTouchEvents(<object>, true); // ignore events on childs

Here is the code i wrote. I used some nice tricks to speed up evaluating things (see code).

function simulateTouchEvents(oo,bIgnoreChilds)
{
 if( !$(oo)[0] )
  { return false; }

 if( !window.__touchTypes )
 {
   window.__touchTypes  = {touchstart:'mousedown',touchmove:'mousemove',touchend:'mouseup'};
   window.__touchInputs = {INPUT:1,TEXTAREA:1,SELECT:1,OPTION:1,'input':1,'textarea':1,'select':1,'option':1};
 }

$(oo).bind('touchstart touchmove touchend', function(ev)
{
    var bSame = (ev.target == this);
    if( bIgnoreChilds && !bSame )
     { return; }

    var b = (!bSame && ev.target.__ajqmeclk), // Get if object is already tested or input type
        e = ev.originalEvent;
    if( b === true || !e.touches || e.touches.length > 1 || !window.__touchTypes[e.type]  )
     { return; } //allow multi-touch gestures to work

    var oEv = ( !bSame && typeof b != 'boolean')?$(ev.target).data('events'):false,
        b = (!bSame)?(ev.target.__ajqmeclk = oEv?(oEv['click'] || oEv['mousedown'] || oEv['mouseup'] || oEv['mousemove']):false ):false;

    if( b || window.__touchInputs[ev.target.tagName] )
     { return; } //allow default clicks to work (and on inputs)

    // https://developer.mozilla.org/en/DOM/event.initMouseEvent for API
    var touch = e.changedTouches[0], newEvent = document.createEvent("MouseEvent");
    newEvent.initMouseEvent(window.__touchTypes[e.type], true, true, window, 1,
            touch.screenX, touch.screenY,
            touch.clientX, touch.clientY, false,
            false, false, false, 0, null);

    touch.target.dispatchEvent(newEvent);
    e.preventDefault();
    ev.stopImmediatePropagation();
    ev.stopPropagation();
    ev.preventDefault();
});
 return true;
}; 

What it does: At first, it translates single touch events into mouse events. It checks if an event is caused by an element on/in the element that must be dragged around. If it is an input element like input, textarea etc, it skips the translation, or if a standard mouse event is attached to it it will also skip a translation.

Result: Every element on a draggable element is still working.

Happy coding, greetz, Erwin Haantjes

QUICK HELP 1: To add a certificate in the simple PEM or DER file formats to the list of CAs trusted on the system:

• add it as a new file to directory /etc/pki/ca-trust/source/anchors/

• run update-ca-trust extract

QUICK HELP 2: If your certificate is in the extended BEGIN TRUSTED file format (which may contain distrust/blacklist trust flags, or trust flags for usages other than TLS) then:

• add it as a new file to directory /etc/pki/ca-trust/source/
• run update-ca-trust extract

Changing the sdk location in Project Settings will solve the problem partially. When Android Studio is used to download a new SDK, it will place the new SDK in the internal SDK folder (inside Android Studio).

Existing android developers will already have a large sdks folder (hereinafter referred to as external SDK folder) containing all the SDKs downloaded before Android Studio came around.

For Mac/Linux users though there is a good way out. Soft links!

Exit Android Studio and perform the following steps:

cp -r <Android Studio>/sdk/ <external SDK folder>/
cd <Android Studio>/
mv <Android Studio>/sdk/ mv <Android Studio>/sdk.orig
ln -s <external SDK folder>/ sdk

And we're good to go. Launch SDK Manager after starting Android Studio, watch as it discovers all your existing SDKs like a charm :).

The immediate problem is you have is with quoting: by using double quotes ("..."), your variable references are instantly expanded, which is probably not what you want.

Use single quotes instead - strings inside single quotes are not expanded or interpreted in any way by the shell.

(If you want selective expansion inside a string - i.e., expand some variable references, but not others - do use double quotes, but prefix the $ of references you do not want expanded with \; e.g., \$var).

However, you're better off using a single here-doc[ument], which allows you to create multi-line stdin input on the spot, bracketed by two instances of a self-chosen delimiter, the opening one prefixed by <<, and the closing one on a line by itself - starting at the very first column; search for Here Documents in man bash or at http://www.gnu.org/software/bash/manual/html_node/Redirections.html.

If you quote the here-doc delimiter (EOF in the code below), variable references are also not expanded. As @chepner points out, you're free to choose the method of quoting in this case: enclose the delimiter in single quotes or double quotes, or even simply arbitrarily escape one character in the delimiter with \:

echo "creating new script file."

cat <<'EOF'  > "$servfile"
#!/bin/bash
read -p "Please enter a service: " ser
servicetest=`getsebool -a | grep ${ser}` 
if [ $servicetest > /dev/null ]; then 
  echo "we are now going to work with ${ser}"
else
  exit 1
fi
EOF

As @BruceK notes, you can prefix your here-doc delimiter with - (applied to this example: <<-"EOF") in order to have leading tabs stripped, allowing for indentation that makes the actual content of the here-doc easier to discern. Note, however, that this only works with actual tab characters, not leading spaces.

Employing this technique combined with the afterthoughts regarding the script's content below, we get (again, note that actual tab chars. must be used to lead each here-doc content line for them to get stripped):

cat <<-'EOF' > "$servfile"
    #!/bin/bash
    read -p "Please enter a service name: " ser
    if [[ -n $(getsebool -a | grep "${ser}") ]]; then 
      echo "We are now going to work with ${ser}."
    else
      exit 1
    fi
EOF

Finally, note that in bash even normal single- or double-quoted strings can span multiple lines, but you won't get the benefits of tab-stripping or line-block scoping, as everything inside the quotes becomes part of the string.

Thus, note how in the following #!/bin/bash has to follow the opening ' immediately in order to become the first line of output:

echo '#!/bin/bash
read -p "Please enter a service: " ser
servicetest=$(getsebool -a | grep "${ser}")
if [[ -n $servicetest ]]; then 
  echo "we are now going to work with ${ser}"
else
  exit 1
fi' > "$servfile"

Afterthoughts regarding the contents of your script:

• The syntax $(...) is preferred over `...` for command substitution nowadays.
• You should double-quote ${ser} in the grep command, as the command will likely break if the value contains embedded spaces (alternatively, make sure that the valued read contains no spaces or other shell metacharacters).
• Use [[ -n $servicetest ]] to test whether $servicetest is empty (or perform the command substitution directly inside the conditional) - [[ ... ]] - the preferred form in bash - protects you from breaking the conditional if the $servicetest happens to have embedded spaces; there's NEVER a need to suppress stdout output inside a conditional (whether [ ... ] or [[ ... ]], as no stdout output is passed through; thus, the > /dev/null is redundant (that said, with a command substitution inside a conditional, stderr output IS passed through).

With rails >= 3.0, you can simply use the placeholder option.

f.text_field :attr, placeholder: "placeholder text"

To achieve the 360 degree rotation, here is the Working Solution.

The HTML:

<img class="image" src="your-image.png">

The CSS:

.image {
    overflow: hidden;
    transition-duration: 0.8s;
    transition-property: transform;
}
.image:hover {
    transform: rotate(360deg);
    -webkit-transform: rotate(360deg);
}

You have to hover on the image and you will get the 360 degree rotation effect.

PS: Add a -webkit- extension for it to work on chrome and other webkit browers. You can check the updated fiddle for webkit HERE

You could always do $('input[name="somename"]')

You can try with:

{% if theList.object_list.count > 0 %}
    blah, blah...
{% else %}
    blah, blah....
{% endif %} 

.html() only takes a string OR a function as an argument, not both. Try this:

 $("#showDiv").click(function () {
     $('#theDiv').show(1000, function () {
         setTimeout(function () {
             $('#theDiv').html(function () {
                 setTimeout(function () {
                     $('#theDiv').html('Here is some replacement text');
                 }, 0);
                 setTimeout(function () {
                     $('#theDiv').html('More replacement text goes here');
                 }, 2500);
             });
         }, 2500);
     });
 }); //click function ends

How to debug SQL queries when you stuck

Print you query and run it directly in mysql or phpMyAdmin

$date = "2012-08-06";
$query= "INSERT INTO data_table (title, date_of_event) 
             VALUES('". $_POST['post_title'] ."',
                    '". $date ."')";
echo $query;
mysql_query($query) or die(mysql_error()); 

that way you can make sure that the problem is not in your PHP-script, but in your SQL-query

According to Flexbugs:

In IE 10-11, min-height declarations on flex containers work to size the containers themselves, but their flex item children do not seem to know the size of their parents. They act as if no height has been set at all.

Here are a couple of workarounds:

1. Always fill the viewport + scrollable <aside> and <section>:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1;

Add another div or img to your main div and blur that instead. jsfiddle

.blur {
    background:url('http://i0.kym-cdn.com/photos/images/original/000/051/726/17-i-lol.jpg?1318992465') no-repeat center;

If you want to do an ajax call or a simple javascript function, don't forget to close your function with the return false

like this:

function DoAction(id, name) 
{ 
    // your code
    return false;
}

1. Find the right version of your anaconda

2. Put it to ~/.zshrc via command vim ~/.zshrc

   • Anaconda 2 export PATH="/User/<your-username>/anaconda2/bin:$PATH"
   • Anaconda 3 export PATH="/User/<your-username>/anaconda3/bin:$PATH"
   • Or if you install Anaconda in root directory:
   • Anaconda 2 export PATH="/anaconda2/bin:$PATH"
   • Anaconda 3 export PATH="/anaconda3/bin:$PATH"

3. Restart the zsh source ~/.zshrc

Here is the simple solution for it assuming the data type is varchar

select * from calender where year > 0

It will return true if the year is numeric else false

Codecs proper:

ffmpeg -codecs

Formats:

ffmpeg -formats

Simply use this function and pass the count of number you want to generate

Code:

function randomFix($length)
{
    $random= "";

srand((double)microtime()*1000000);

$data = "AbcDE123IJKLMN67QRSTUVWXYZ";
$data .= "aBCdefghijklmn123opq45rs67tuv89wxyz";
$data .= "0FGH45OP89";

for($i = 0; $i < $length; $i++)
{
    $random .= substr($data, (rand()%(strlen($data))), 1);
}
return $random;}

TL;DR: Specify key file in group variable file, since 'tag_Name_server1' is a group.

Note: I'm assuming you're using the EC2 external inventory script. If you're using some other dynamic inventory approach, you might need to tweak this solution.

This is an issue I've been struggling with, on and off, for months, and I've finally found a solution, thanks to Brian Coca's suggestion here. The trick is to use Ansible's group variable mechanisms to automatically pass along the correct SSH key file for the machine you're working with.

The EC2 inventory script automatically sets up various groups that you can use to refer to hosts. You're using this in your playbook: in the first play, you're telling Ansible to apply 'role1' to the entire 'tag_Name_server1' group. We want to direct Ansible to use a specific SSH key for any host in the 'tag_Name_server1' group, which is where group variable files come in.

Assuming that your playbook is located in the 'my-playbooks' directory, create files for each group under the 'group_vars' directory:

my-playbooks
|-- test.yml
+-- group_vars
     |-- tag_Name_server1.yml
     +-- tag_Name_server2.yml

Now, any time you refer to these groups in a playbook, Ansible will check the appropriate files, and load any variables you've defined there.

Within each group var file, we can specify the key file to use for connecting to hosts in the group:

# tag_Name_server1.yml
# --------------------
# 
# Variables for EC2 instances named "server1"
---
ansible_ssh_private_key_file: /path/to/ssh/key/server1.pem

Now, when you run your playbook, it should automatically pick up the right keys!

Using environment vars for portability

I often run playbooks on many different servers (local, remote build server, etc.), so I like to parameterize things. Rather than using a fixed path, I have an environment variable called SSH_KEYDIR that points to the directory where the SSH keys are stored.

In this case, my group vars files look like this, instead:

# tag_Name_server1.yml
# --------------------
# 
# Variables for EC2 instances named "server1"
---
ansible_ssh_private_key_file: "{{ lookup('env','SSH_KEYDIR') }}/server1.pem"

Further Improvements

There's probably a bunch of neat ways this could be improved. For one thing, you still need to manually specify which key to use for each group. Since the EC2 inventory script includes details about the keypair used for each server, there's probably a way to get the key name directly from the script itself. In that case, you could supply the directory the keys are located in (as above), and have it choose the correct keys based on the inventory data.

Attributes and methods marked as protected are -- unlike private ones -- still visible in subclasses.

Unless you don't want to use or provide the possibility to override the method in possible subclasses, I'd make them private.

just use frame.setVisible(false); frame.setVisible(true); I've had this problem with JLabels with images, and this solved it

You need to define something in the interface, such as:

public interface ITest
{
    string Name { get; }
}

Implement ITest in your classes:

public class MyClass1 : ITest
{
    public string Name { get { return "Test1"; } }
}

public class MyClass2 : ITest
{
    public string Name { get { return "Test2"; } }
}

Then restrict your generic Print function, to ITest:

public void Print<T>(T test) where T : ITest
{
}

The servlet container loads the servlet during startup or when the first request is made. The loading of the servlet depends on the attribute "load-on-startup" in "web.xml" file. If the attribute has a positive integer(0 to 128) then the servlet is load with the loading of the container otherwise it loads when the first request comes for service.

When the servlet is loaded once it gets request then it is called "Lazy loading".

If you have sklearn isntalled, a simple alternative is to use sklearn.metrics.auc

This computes the area under the curve using the trapezoidal rule given arbitrary x, and y array

import numpy as np
from sklearn.metrics import auc

dx = 5
xx = np.arange(1,100,dx)
yy = np.arange(1,100,dx)

print('computed AUC using sklearn.metrics.auc: {}'.format(auc(xx,yy)))
print('computed AUC using np.trapz: {}'.format(np.trapz(yy, dx = dx)))

both output the same area: 4607.5

the advantage of sklearn.metrics.auc is that it can accept arbitrarily-spaced 'x' array, just make sure it is ascending otherwise the results will be incorrect

This should do the trick just using the OS module to list and then remove!

import os
DIR = os.list('Folder')
for i in range(len(DIR)):
    os.remove('Folder'+chr(92)+i)

Worked for me, any problems let me know!

Also you will need to zoom and center the map due to your country restrictions!

Just use zoom and center parameters! ;)

function initialize() {
  var myOptions = {
    zoom: countries['us'].zoom,
    center: countries['us'].center,
    mapTypeControl: false,
    panControl: false,
    zoomControl: false,
    streetViewControl: false
  };

  ... all other code ...

}

For a single file you can use -O instead of -o filename to use the last segment of the URL path as the filename. Example:

curl http://example.com/folder/big-file.iso -O

will save the results to a new file named big-file.iso in the current folder. In this way it works similar to wget but allows you to specify other curl options that are not available when using wget.

For Eloquent you can just do:

$result->getQuery()->toSql();

But you need to remove the "->get()" part from your query.

I also encountered this problem. I found after changing the table storage engine from MyISAM to Innodb, problem solved .

I was facing the same issues recently and found a solution which worked for me and reduced the memory consumption level upto a great extent.

Solution:

First of all find the application which is causing heavy memory usage.

You can find this in the Details section of the Task Manager.

Next.

1. Open the IIS manager.
2. Click on Application Pools. You'll find many application pools which your system is using.
3. Now from the task manager you've found which application is causing the heavy memory consumption. There would be multiple options for that and you need to select the one which is having '1' in it's Application column of your web application.
4. When you click on the application pool on the right hand side you'll see an option Advance settings under Edit Application pools. Go to Advanced Settings. 5.Now under General category set the Enable 32-bit Applications to True
5. Restart the IIS server or you can see the consumption goes down in performance section of your Task Manager.

If this solution works for you please add a comment so that I can know.

Google has a serious liking for goats and goat based Easter eggs. There has even been previous Stack Overflow posts about it.

As has been mentioned in previous posts, it also exists within the Chrome task manager (it first appeared in the wild in 2009):

<message name="IDS_TASK_MANAGER_GOATS_TELEPORTED_COLUMN" desc="The goats teleported column">
    Goats Teleported
</message>

And then in Windows, Linux and Mac versions of Chrome early 2010). The number of "Goats Teleported" is in fact random:

 int TaskManagerModel::GetGoatsTeleported(int index) const {
     int seed = goat_salt_ * (index + 1);
     return (seed >> 16) & 255;
 }

Other Google references to goats include:

• Mowing with goats
• The goats are baaaahk

The earliest correlation of goats and Google belongs in the original "Mowing with goats" blog post, as far as I can tell.

We can safely assume that it's merely an Easter egg and has no real-world use, except for returning false.

It is a way to simplify error checking and avoid deep nested if's. For example:

do {
  // do something
  if (error) {
    break;
  }
  // do something else
  if (error) {
    break;
  }
  // etc..
} while (0);

Short ONELINER:

<input onkeypress="return /[a-z]/i.test(event.key)" >

For all unicode letters try this regexp: /\p{L}/u (but ... this) - and here is working example :)

At 99% the Could not load file or assembly or one of its dependencies problem is caused by dependencies! I suggest you follow this steps:

1. Download Dependency Walker from http://www.dependencywalker.com/

2. Launch Dependency Walker and open the dll (in my case NativeInterfaces.dll)

3. You can see one or more dll with the error in red Error opening file...

4. It means that this dll is missing in your system; in my case the dll name is MSVCR71.DLL

5. You can download missings dll from google and copy in right path (in my case c:\windows\system32)

6. At this point, you must register the new dll in the GAC (Global Assembly Cache): open a DOS terminal and write:

    cd \Windows\System32
    regsvr32 /i msvcr71.dll
   

7. Restart your application

You can use push and apply function to append two arrays.

var array1 = [11, 32, 75];_x000D_
var array2 = [99, 67, 34];_x000D_
_x000D_
Array.prototype.push.apply(array1, array2);_x000D_
console.log(array1);

It will append array2 to array1. Now array1 contains [11, 32, 75, 99, 67, 34]. This code is much simpler than writing for loops to copy each and every items in the array.

Starting Java 8, there is support for unsigned long (unsigned 64 bits). The way you can use it is:

Long l1 = Long.parseUnsignedLong("17916881237904312345");

To print it, you can not simply print l1, but you have to first:

String l1Str = Long.toUnsignedString(l1)

Then

System.out.println(l1Str);

The example from MySQL documentation http://dev.mysql.com/doc/refman/5.1/en/problems-with-float.html (i shrink it, documentation for this section is the same for 5.5)

mysql> create table t1 (i int, d1 double, d2 double);

mysql> insert into t1 values (2, 0.00  , 0.00),
                             (2, -13.20, 0.00),
                             (2, 59.60 , 46.40),
                             (2, 30.40 , 30.40);

mysql> select
         i,
         sum(d1) as a,
         sum(d2) as b
       from
         t1
       group by
         i
       having a <> b; -- a != b

+------+-------------------+------+
| i    | a                 | b    |
+------+-------------------+------+
|    2 | 76.80000000000001 | 76.8 |
+------+-------------------+------+
1 row in set (0.00 sec)

Basically if you sum a you get 0-13.2+59.6+30.4 = 76.8. If we sum up b we get 0+0+46.4+30.4=76.8. The sum of a and b is the same but MySQL documentation says:

A floating-point value as written in an SQL statement may not be the same as the value represented internally.

If we repeat the same with decimal:

mysql> create table t2 (i int, d1 decimal(60,30), d2 decimal(60,30));
Query OK, 0 rows  affected (0.09 sec)

mysql> insert into t2 values (2, 0.00  , 0.00),
                             (2, -13.20, 0.00),
                             (2, 59.60 , 46.40),
                             (2, 30.40 , 30.40);
Query OK, 4 rows affected (0.07 sec)
Records: 4  Duplicates: 0  Warnings: 0

mysql> select
         i,
         sum(d1) as a,
         sum(d2) as b
       from
         t2
       group by
         i
       having a <> b;

Empty set (0.00 sec)

The result as expected is empty set.

So as long you do not perform any SQL arithemetic operations you can use DOUBLE, but I would still prefer DECIMAL.

Another thing to note about DECIMAL is rounding if fractional part is too large. Example:

mysql> create table t3 (d decimal(5,2));
Query OK, 0 rows affected (0.07 sec)

mysql> insert into t3 (d) values(34.432);
Query OK, 1 row affected, 1 warning (0.10 sec)

mysql> show warnings;
+-------+------+----------------------------------------+
| Level | Code | Message                                |
+-------+------+----------------------------------------+
| Note  | 1265 | Data truncated for column 'd' at row 1 |
+-------+------+----------------------------------------+
1 row in set (0.00 sec)

mysql> select * from t3;
+-------+
| d     |
+-------+
| 34.43 |
+-------+
1 row in set (0.00 sec)

This is the solution which can avoid using function:

alias addone='{ num=$(cat -); echo "input: $num"; echo "result:$(($num+1))"; }<<<'

test result

addone 200
input: 200
result:201

You first mention this code:

throw new Error('sample')

and then in your first example you write:

throw new Error({'hehe':'haha'}) 

The first Error object would actually be useful, because it is expecting a string value, in this case 'sample'. The second would not because you are trying to pass an object in, and it is expecting a string, and would not display a helpful error.

The error object would have the "message" property, which would be 'sample'.

Let me present to you a glorious but terrifying hack:

import types

def _obj():
  return lambda: None

def LET(bindings, body, env=None):
  '''Introduce local bindings.
  ex: LET(('a', 1,
           'b', 2),
          lambda o: [o.a, o.b])
  gives: [1, 2]

  Bindings down the chain can depend on
  the ones above them through a lambda.
  ex: LET(('a', 1,
           'b', lambda o: o.a + 1),
          lambda o: o.b)
  gives: 2
  '''
  if len(bindings) == 0:
    return body(env)

  env = env or _obj()
  k, v = bindings[:2]
  if isinstance(v, types.FunctionType):
    v = v(env)

  setattr(env, k, v)
  return LET(bindings[2:], body, env)

You can now use this LET form as such:

map(lambda x: LET(('_', x.sort()),
                  lambda _: x[1]),
    lst)

which gives: [345, 465, 333]

You can try and do a simple GET on the page, if you get a 200 back it means the page exists. Try this (using jQuery), the function is the success callback function on a successful page load. Note this will only work on sites within your domain to prevent XSS. Other domains will have to be handled server side

$.get(
   yourURL,
   function(data, textStatus, jqXHR) {
      //load the iframe here...
   }
);

Check first your class loader.

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

if (classLoader == null) {
    classLoader = Class.class.getClassLoader();
}

classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");

// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml

Seeing as Guava gets a mention, I thought I would also suggest Eclipse Collections (formerly known as GS Collections).

The following examples all return a List with a single item.

Lists.mutable.of("Just one item");
Lists.mutable.with("Or use with");
Lists.immutable.of("Maybe it must be immutable?");
Lists.immutable.with("And use with if you want");

There are similar methods for other collections.

dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;

If this is something you are only going to need to do once, have you considered downloading a demo version of Crystal? There's a 30-day trial version available here: http://www.developers.net/businessobjectsshowcase/view/3154

Of course, if you need to edit these files after the 30 day period is over, you would be better off buying Crystal.

Alternatively, if all you need to do is replace a few static literal words, have you tried doing a search and replace in a text editor? (Don't forget to save the original files somewhere safe first!)

This is what I used to copy some resource files: the copy-files is an empty target to ignore errors

 add_custom_target(copy-files ALL
    COMMAND ${CMAKE_COMMAND} -E copy_directory
    ${CMAKE_BINARY_DIR}/SOURCEDIRECTORY
    ${CMAKE_BINARY_DIR}/DESTINATIONDIRECTORY
    )

To update this, in Swift it can be done easily with:

array.reverse()

It can be used for a simple table, for example in an insert-only audit table, where there is no update to existing row, and no fk to other table. The insert is a simple insert, which has no or little chance of rollback.

for kotlin users, here my extension to check and validate permissions without override onRequestPermissionResult

 * @param permissionToValidate (request and check currently permission)
 *
 * @return recursive boolean validation callback (no need OnRequestPermissionResult)
 *
 * */
internal fun Activity.validatePermission(
    permissionToValidate: String,
    recursiveCall: (() -> Boolean) = { false }
): Boolean {
    val permission = ContextCompat.checkSelfPermission(
        this,
        permissionToValidate
    )

    if (permission != PackageManager.PERMISSION_GRANTED) {
        if (recursiveCall()) {
            return false
        }

        ActivityCompat.requestPermissions(
            this,
            arrayOf(permissionToValidate),
            110
        )
        return this.validatePermission(permissionToValidate) { true }
    }

    return true

}

we can use this type of snippet also we generally use this kind of code for testing and validating data for DB to API fields

class Db
{
    private readonly static string ConnectionString =
            ConfigurationManager.ConnectionStrings
                        ["DbConnectionString"].ConnectionString;
    public static List<string> GetValuesFromDB(string LocationCode)
    {
        List<string> ValuesFromDB = new List<string>();
        string LocationqueryString = "select BELocationCode,CityLocation,CityLocationDescription,CountryCode,CountryDescription " +
            $"from [CustomerLocations] where LocationCode='{LocationCode}';";
        using (SqlConnection Locationconnection =
                                 new SqlConnection(ConnectionString))
        {
            SqlCommand command = new SqlCommand(LocationqueryString, Locationconnection);
            try
            {
                Locationconnection.Open();
                SqlDataReader Locationreader = command.ExecuteReader();
                while (Locationreader.Read())
                {
                    for (int i = 0; i <= Locationreader.FieldCount - 1; i++)
                    {
                        ValuesFromDB.Add(Locationreader[i].ToString());
                    }
                }
                Locationreader.Close();
                return ValuesFromDB;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                throw;
            }
        }

    }

}

hope this might helpful

Note: you guys need connection string (in our case "DbConnectionString")

Use strtotime() function:

  $time = strtotime("-1 year", time());
  $date = date("Y-m-d", $time);

Out of curiosity, why don't you just use the url for the said folder?

http://www.mysite.com/images

Assuming that the folder never changes location, that would be the easiest way to do it.

Assuming you’ve literally got two date objects, you can subtract one from the other and query the resulting timedelta object for the number of days:

>>> from datetime import date
>>> a = date(2011,11,24)
>>> b = date(2011,11,17)
>>> a-b
datetime.timedelta(7)
>>> (a-b).days
7

And it works with datetimes too — I think it rounds down to the nearest day:

>>> from datetime import datetime
>>> a = datetime(2011,11,24,0,0,0)
>>> b = datetime(2011,11,17,23,59,59)
>>> a-b
datetime.timedelta(6, 1)
>>> (a-b).days
6

Although it is not a good solution but may solve your problem. You need to use position absolute in #yellow element!

#yellow {height: 100%; background: yellow; position: absolute; top: 0px; left: 0px;}_x000D_
.container-fluid {position: static !important;}

Here's how you do it for SQL Server. Someone else can translate it to MySQL. Parsing CSV Values Into Multiple Rows.

SELECT Author, 
NullIf(SubString(',' + Phrase + ',' , ID , CharIndex(',' , ',' + Phrase + ',' , ID) - ID) , '') AS Word 
FROM Tally, Quotes 
WHERE ID <= Len(',' + Phrase + ',') AND SubString(',' + Phrase + ',' , ID - 1, 1) = ',' 
AND CharIndex(',' , ',' + Phrase + ',' , ID) - ID > 0

The idea is to cross join to a predefined table Tally which contains integer 1 through 8000 (or whatever big enough number) and run SubString to find the right ,word, position.

As far as I know, QPixmap is used for displaying images and QImage for reading them. There are QPixmap::convertFromImage() and QPixmap::fromImage() functions to convert from QImage.

Swift 4.0 possible solution using UIButton

     phoneButton = UIButton(frame: CGRect(x: view.frame.width * 0, y: view.frame.height * 0.1, width: view.frame.width * 1, height: view.frame.height * 0.05))
     phoneButton.setTitle("333-333-3333", for: .normal )
     phoneButton.setTitleColor(UIColor(red: 0 / 255, green: 0 / 255, blue: 238 / 255, alpha: 1.0), for: .normal)
     phoneButton.addTarget(self, action: #selector(self.callPhone), for: .touchUpInside )

     @objc func callPhone(){

         UIApplication.shared.open(URL(string:"tel://3333333333")!, options: [:] , completionHandler: nil)


    }

if b > 0:
    int mod = (mod = a % b) < 0 ? a + b : a;

Doesn't use the % operator twice.

declare @store table (store_id varchar(300))
insert into @store 
values ('aa'),('bb'),('cc')
declare @str varchar (4000)
select @str = concat(@str+',',store_id) from @store
select @str

to get the number of days in a time range (just a count of all days)

(start_date..end_date).count
(start_date..end_date).to_a.size
#=> 32

to get the number of days between 2 dates

(start_date...end_date).count
(start_date...end_date).to_a.size
#=> 31

This is an old post, but I thought I should provide an illustrated answer anyway.

Use javascript's object notation. Like so:

states_dictionary={ 
     "CT":["alex","harry"], 
     "AK":["liza","alex"], 
     "TX":["fred", "harry"]
};

And to access the values:

states_dictionary.AK[0] //which is liza

or you can use javascript literal object notation, whereby the keys not require to be in quotes:

states_dictionary={ 
     CT:["alex","harry"], 
     AK:["liza","alex"], 
     TX:["fred", "harry"]
};

There is a file you have to read with:

cat /etc/sudoers.d/README

Placing a file with mode 0440 in /etc/sudoers.d/myuser with following content:

myuser  ALL=(ALL) NOPASSWD: ALL

Should fix the issue.

Do not forget to:

chmod 0440 /etc/sudoers.d/myuser

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

You could try argmax like this:

dataframe['name'].value_counts().argmax() Out[13]: 'alex'

The value_counts will return a count object of pandas.core.series.Series and argmax could be used to achieve the key of max values.

In my case (sam problem, but other packages) there was no version dependency. A sequence of pip uninstall and pip insstall did help.

It's the quickest way I've found without doing any subclasses:

UIView *spacerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10., 10.)];
[textField setLeftViewMode:UITextFieldViewModeAlways];
[textField setLeftView:spacerView];

In Swift:

let spacerView = UIView(frame:CGRect(x:0, y:0, width:10, height:10))
textField.leftViewMode = UITextFieldViewMode.Always
textField.leftView = spacerView

You have to create an object. Assign the values to the object. Then push it into the array:

var nietos = [];
var obj = {};
obj["01"] = nieto.label;
obj["02"] = nieto.value;
nietos.push(obj);

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

If you really must output every values including the NULL ones:

select IFNULL(prereq,"") from test

You can get a view for a particular position on a recyclerview using the following

int position = 2;
RecyclerView.ViewHolder viewHolder = recyclerview.findViewHolderForItemId(position);
View view = viewHolder.itemView;
ImageView imageView = (ImageView)view.findViewById(R.id.imageView);

Do your databinding and then add the following:

Dim liFirst As New ListItem("", "")
drpList.Items.Insert(0, liFirst)

Beware of using vars as the target directory name for WORKDIR - doing that appears to result in a "cannot normalize nothing" fatal error. IMO, it's also worth pointing out that WORKDIR behaves in the same way as mkdir -p <path> i.e. all elements of the path are created if they don't exist already.

UPDATE: I encountered the variable related problem (mentioned above) whilst running a multi-stage build - it now appears that using a variable is fine - if it (the variable) is "in scope" e.g. in the following, the 2nd WORKDIR reference fails ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
WORKDIR $varname

whereas, it succeeds in this ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
ENV varname varval
WORKDIR $varname

.oO(Maybe it's in the docs & I've missed it)

this is your first Activity1.

public class Activity1 extends Activity{
private int mRequestCode = 100;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = new Intent(this, Activity2.class);
    startActivityForResult(intent, mRequestCode);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == mRequestCode && resultCode == RESULT_OK){
        String editTextString = data.getStringExtra("editText");
    }
}
}

From here you are starting your Activity2.class by using startActivityForResult(mRequestCode, Activity2.class);

Now this is your second Activity, name is Activity2

public class Activity2 extends Activity {
private EditText mEditText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //mEditText = (EditText)findViewById(R.id.edit_text);

    Intent intent = new Intent();
    intent.putExtra("editText", mEditText.getText().toString());
    setResult(RESULT_OK, intent);
}

}

Now when you done with your second Activity then you call setResult() method, from onBackPress() or from any button click when your Activity2 will destroy then your Activity1's call back method onActivityResult() will call from there you can get your data from intent..

Hope it will help to you...:)

You can also import the data via the "Import Dataset" tab in RStudio, under "global environment." Use the text data option in the drop down list and select your .RData file from the folder. Once the import is complete, it will display the data in the console. Hope this helps.

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

EXCEPTION
      WHEN DUP_VAL_ON_INDEX
      THEN
         UPDATE

why not

def pairwise(iterable):
    "s -> (s0,s1), (s1,s2), (s2, s3), ..."
    a, b = tee(iterable)
    next(b, None)
    return zip(a, b)

It is documented in Python doc . You can easily extend it to wider window.

Use finish like this:

Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish();  //Kill the activity from which you will go to next activity 
startActivity(i);

FLAG_ACTIVITY_NO_HISTORY you can use in case for the activity you want to finish. For exampe you are going from A-->B--C. You want to finish activity B when you go from B-->C so when you go from A-->B you can use this flag. When you go to some other activity this activity will be automatically finished.

To learn more on using Intent.FLAG_ACTIVITY_NO_HISTORY read: http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NO_HISTORY

The HTML spec here is really broken. It should allow nested optgroups and recommend user agents render them as nested menus. Instead, only one optgroup level is allowed. However, they do have to say the following on the subject:

Note. Implementors are advised that future versions of HTML may extend the grouping mechanism to allow for nested groups (i.e., OPTGROUP elements may nest). This will allow authors to represent a richer hierarchy of choices.

And user agents could start using submenus to render optgoups instead of displaying titles before the first option element in an optgroup as they do now.

By default . (any character) does not match newline characters.

This means you can simply match zero or more of any character then append the end tag.

Find: <li><a href="#">.* Replace: $0</a>

The accepted answer doesn't work if some package vendors it's own copy of urllib3, in which case this will still work:

import warnings

warnings.filterwarnings('ignore', message='Unverified HTTPS request')

Without using any extra plugins,

var myOptions = {
    val1 : 'text1',
    val2 : 'text2'
};
var mySelect = $('#mySelect');
$.each(myOptions, function(val, text) {
    mySelect.append(
        $('<option></option>').val(val).html(text)
    );
});

If you had lots of options, or this code needed to be run very frequently, then you should look into using a DocumentFragment instead of modifying the DOM many times unnecessarily. For only a handful of options, I'd say it's not worth it though.

------------------------------- Added --------------------------------

DocumentFragment is good option for speed enhancement, but we cannot create option element using document.createElement('option') since IE6 and IE7 are not supporting it.

What we can do is, create a new select element and then append all options. Once loop is finished, append it to actual DOM object.

var myOptions = {
    val1 : 'text1',
    val2 : 'text2'
};
var _select = $('<select>');
$.each(myOptions, function(val, text) {
    _select.append(
            $('<option></option>').val(val).html(text)
        );
});
$('#mySelect').append(_select.html());

This way we'll modify DOM for only one time!

JavaScript has an eval function that evaluates a string and executes it as code:

eval(settings.functionName + '(' + t.parentNode.id + ')');

To test that all words start with an upper case use this:

print all(word[0].isupper() for word in words)

Just typing this single line would give you a json array ,

echo json_encode($array);

Normally you use json_encode to read data from an ios or android app. so make sure you do not echo anything else other than the accurate json array.

Comment.find(:all, :conditions =>["date(created_at) BETWEEN ? AND ? ", '2011-11-01','2011-11-15'])

This has been driving me crazy all day (since indeed you can't control the Excel column types before opening the CSV file), and this worked for me, using VB.NET and Excel Interop:

        'Convert .csv file to .txt file.
        FileName = ConvertToText(FileName)

        Dim ColumnTypes(,) As Integer = New Integer(,) {{1, xlTextFormat}, _
                                                        {2, xlTextFormat}, _
                                                        {3, xlGeneralFormat}, _
                                                        {4, xlGeneralFormat}, _
                                                        {5, xlGeneralFormat}, _
                                                        {6, xlGeneralFormat}}

        mxlWorkBook = mxlApp.ActiveWorkbook
        mxlWorkSheet = CType(mxlApp.ActiveSheet, Excel.Worksheet)


Private Function ConvertToText(ByVal FileName As String) As String
    'Convert the .csv file to a .txt file.

        Dim MyWriter As New StreamWriter(NewFileName, False)
        Dim strLine As String

        Do While Not MyReader.EndOfStream

The patch is here: https://code.ros.org/trac/opencv/attachment/ticket/862/OpenCV-2.2-nov4l1.patch

By adding #ifdef HAVE_CAMV4L around

#include <linux/videodev.h>

in OpenCV-2.2.0/modules/highgui/src/cap_v4l.cpp and removing || defined (HAVE_CAMV4L2) from line 174 allowed me to compile.

Short version :

run iptables on the host before to run it in the virtual server (I'm pretty sure this is some sort of LXC or OpenVZ container here).

Long version :

The problem is due to the fact that the ip_table module is loaded on demand. So, after a reboot, on any machine that does not have any iptables rules loaded at boot time, the ip_tables module is not loaded (no demand for the modules == the module is not loaded). Consequently, the LXC or OpenVZ containers cannot use iptables (since they share the host kernel but cannot modify which modules are loaded) until the host has somehow loaded the ip_tables module.

If you using the node-mysql module, just remove the .connect and .end. Just solved the problem myself. Apparently they pushed in unnecessary code in their last iteration that is also bugged. You don't need to connect if you have already ran the createConnection call

You can use the DevExpress PdfDocumentProcessor.Print(PdfPrinterSettings) Method.

public void Print(string pdfFilePath)
{
      if (!File.Exists(pdfFilePath))
          throw new FileNotFoundException("No such file exists!", pdfFilePath);

      // Create a Pdf Document Processor instance and load a PDF into it.
      PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor();
      documentProcessor.LoadDocument(pdfFilePath);

      if (documentProcessor != null)
      {
          PrinterSettings settings = new PrinterSettings();

          //var paperSizes = settings.PaperSizes.Cast<PaperSize>().ToList();
          //PaperSize sizeCustom = paperSizes.FirstOrDefault<PaperSize>(size => size.Kind == PaperKind.Custom); // finding paper size

          settings.DefaultPageSettings.PaperSize = new PaperSize("Label", 400, 600);

          // Print pdf
          documentProcessor.Print(settings);
      }
}

You get the value of the textarea, use it :

$('.type').keyup(function() {
    var v = $('.type').val(); // you'd better use this.value here
    if (v.indexOf('> <')!=-1) {
       console.log('contains > <');        
    }
});

Another solution if you want to be certain that this is cross-browser capable is to remove() the tag and then append() or prepend() or in some other way re-add a new instance of the input tag with the same attributes.

<form method="POST" enctype="multipart/form-data">
<label for="fileinput">
 <input type="file" name="fileinput" id="fileinput" />
</label>
</form>

$("#fileinput").remove();
$("<input>")
  .attr({
    type: 'file',
    id: 'fileinput',
    name: 'fileinput'
    })
  .appendTo($("label[for='fileinput']"));

you can try this when you write the recpient emails on a text file

from email.mime.text import MIMEText
from email.header import Header
import smtplib

f =  open('emails.txt', 'r').readlines()
for n in f:
     emails = n.rstrip()
server = smtplib.SMTP('smtp.uk.xensource.com')
server.ehlo()
server.starttls()
body = "Test Email"
subject = "Test"
from = "[email protected]"
to = emails
msg = MIMEText(body,'plain','utf-8')
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] =  Header(from, 'utf-8')
msg['To'] = Header(to, 'utf-8')
text = msg.as_string()
try:
   server.send(from, emails, text)
   print('Message Sent Succesfully')
except:
   print('There Was An Error While Sending The Message')

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

I would consider using java.util.concurrent.PriorityBlockingQueue, with priority determined by a "numberOfUses" counter in each element. I would be very, very careful to get all my synchronisation correct, as the "numberOfUses" counter implies that the element can't be immutable.

The element object would be a wrapper for the objects in the cache:

class CacheElement {
    private final Object obj;
    private int numberOfUsers = 0;

    CacheElement(Object obj) {
        this.obj = obj;
    }

    ... etc.
}

What is that BasePagerAdapter? You should use one of the standard pager adapters -- either FragmentPagerAdapter or FragmentStatePagerAdapter, depending on whether you want Fragments that are no longer needed by the ViewPager to either be kept around (the former) or have their state saved (the latter) and re-created if needed again.

Sample code for using ViewPager can be found here

It is true that the management of fragments in a view pager across activity instances is a little complicated, because the FragmentManager in the framework takes care of saving the state and restoring any active fragments that the pager has made. All this really means is that the adapter when initializing needs to make sure it re-connects with whatever restored fragments there are. You can look at the code for FragmentPagerAdapter or FragmentStatePagerAdapter to see how this is done.

There are multiple right answers here. I don't see the VIM version of it so here it is. Open your file in VIM, check the bottom status line for example, execute set ff=dos (for CRLF) or set ff=unix (for LF).

Oracle database to display the names of all tables using below query

SELECT owner, table_name FROM dba_tables;

SELECT owner, table_name FROM all_tables;

SELECT table_name FROM user_tables;

I derived from This answer by sclarke81. I like his answer and I'm using the derivative but sclarke81's has a bug. I don't have reputation so I can't comment. The problem seems small enough that it didn't warrant another answer and I could edit it. So I did. It got rejected. So now we have another answer.

sclarke81 I hope you see this (in finally):

Marshal.Copy(new byte[length], 0, insecureStringPointer, length);

should be:

Marshal.Copy(new byte[length * 2], 0, insecureStringPointer, length * 2);

And the full answer with the bug fix:

Like this.

function printMousePos(event) {_x000D_
  document.body.textContent =_x000D_
    "clientX: " + event.clientX +_x000D_
    " - clientY: " + event.clientY;_x000D_
}_x000D_
_x000D_
document.addEventListener("click", printMousePos);

MouseEvent - MDN

MouseEvent.clientX Read only
The X coordinate of the mouse pointer in local (DOM content) coordinates.

MouseEvent.clientY Read only
The Y coordinate of the mouse pointer in local (DOM content) coordinates.

RaeLehman's solution works if you only want to generate the dialog's content once (or only modify it using javascript). If you actually want to regenerate the dialog each time (e.g., using a view model class and Razor), then you can close all dialogs with $(".ui-dialog-titlebar-close").click(); and leave autoOpen set to its default value of true.

BrenBarn's solution is ideal (and pythonic, I might add). Here is another (fp) solution, however:

from operator import itemgetter
dict(filter(itemgetter(1), metadata.items()))

INNER JOIN: Returns all rows when there is at least one match in BOTH tables

LEFT JOIN: Return all rows from the left table, and the matched rows from the right table

RIGHT JOIN: Return all rows from the right table, and the matched rows from the left table

FULL JOIN: Return all rows when there is a match in ONE of the tables

This is the complete way to omit unneeded redirects, too ;)

These rules are intended to be used in .htaccess files, as a RewriteRule in a *:80 VirtualHost entry needs no Conditions.

RewriteEngine on
RewriteCond %{HTTPS} off [OR] 
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

Eplanations:

RewriteEngine on

==> enable the engine at all

RewriteCond %{HTTPS} off [OR]

==> match on non-https connections, or (not setting [OR] would cause an implicit AND !)

RewriteCond %{HTTP:X-Forwarded-Proto} !https

==> match on forwarded connections (proxy, loadbalancer, etc.) without https

RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

==> if one of both Conditions match, do the rewrite of the whole URL, sending a 301 to have this 'learned' by the client (some do, some don't) and the L for the last rule.

I realize this is an old post, but I ran into the same problem and don't see the correct answer so I will give it a try

Python Error:

_csv.Error: new-line character seen in unquoted field

Caused by trying to read Macintosh (pre OS X formatted) CSV files. These are text files that use CR for end of line. If using MS Office make sure you select either plain CSV format or CSV (MS-DOS). Do not use CSV (Macintosh) as save-as type.

My preferred EOL version would be LF (Unix/Linux/Apple), but I don't think MS Office provides the option to save in this format.

I tried to use awk to print lines between two patterns while pattern2 also match pattern1. And the pattern1 line should also be printed.

e.g. source

package AAA
aaa
bbb
ccc
package BBB
ddd
eee
package CCC
fff
ggg
hhh
iii
package DDD
jjj

should has an ouput of

package BBB
ddd
eee

Where pattern1 is package BBB, pattern2 is package \w*. Note that CCC isn't a known value so can't be literally matched.

In this case, neither @scai 's awk '/abc/{a=1}/mno/{print;a=0}a' file nor @fedorqui 's awk '/abc/{a=1} a; /mno/{a=0}' file works for me.

Finally, I managed to solve it by awk '/package BBB/{flag=1;print;next}/package \w*/{flag=0}flag' file, haha

A little more effort result in awk '/package BBB/{flag=1;print;next}flag;/package \w*/{flag=0}' file, to print pattern2 line also, that is,

package BBB
ddd
eee
package CCC

Try this:

String.prototype.replaceAll = function (sfind, sreplace) {
    var str = this;

    while (str.indexOf(sfind) > -1) {
        str = str.replace(sfind, sreplace);
    }

    return str;
};

Here are three different checkmark styles you can use:

ul:first-child  li:before { content:"\2713\0020"; }  /* OR */_x000D_
ul:nth-child(2) li:before { content:"\2714\0020"; }  /* OR */_x000D_
ul:last-child   li:before { content:"\2611\0020"; }_x000D_
ul { list-style-type: none; }

<ul>_x000D_

In addition to the other answers, there is also the TimeUnit class which allows you to convert one time duration to another. For example, to find out how many milliseconds make up one day:

TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS); //gives 86400000

Note that this method takes a long, so if you have a fraction of a day, you will have to multiply it by the number of milliseconds in one day.

Why all people want to use '==' instead of simple '=' ? It is bad habit! It used only in [[ ]] expression. And in (( )) too. But you may use just = too! It work well in any case. If you use numbers, not strings use not parcing to strings and then compare like strings but compare numbers. like that

let -i i=5 # garantee that i is nubmber
test $i -eq 5 && echo "$i is equal 5" || echo "$i not equal 5"

It's match better and quicker. I'm expert in C/C++, Java, JavaScript. But if I use bash i never use '==' instead '='. Why you do so?

Please Use map() python function.

Input: In case of list of values

index = [u'CARBO1004' u'CARBO1006' u'CARBO1008' u'CARBO1009' u'CARBO1020']

encoded_string = map(str, index)

Output: ['CARBO1004', 'CARBO1006', 'CARBO1008', 'CARBO1009', 'CARBO1020']

For a Single string input:

index = u'CARBO1004'
# Use Any one of the encoding scheme.
index.encode("utf-8")  # To utf-8 encoding scheme
index.encode('ascii', 'ignore')  # To Ignore Encoding Errors and set to default scheme

Output: 'CARBO1004'

Adding something after # sets the focus of page to the element with that ID. Simplest solution is to use #/ even if you are using jQuery. However if you are handling the event in jQuery, event.preventDefault() is the way to go.

Based on Gunther's answer, it seems like in code_editor.xml they're planning to enable a dark mode at some point down the road. What was once fore-color has now been split into fore-color-light and fore-color-dark. Likewise with back-color.

Here's how to get a dark editor (not whole application theme) based on the Monokai colours provided graciously by elMestre:

If you and I each walk into the bank, each open a brand new account, and each deposit $100, then...

1. myAccount.equals(yourAccount) is true because they have the same value, but
2. myAccount == yourAccount is false because they are not the same account.

(Assuming appropriate definitions of the Account class, of course. ;-)

I like Aptana Studio and Redcar for rails programming.

You can do:

setContentPane(new JLabel(new ImageIcon("resources/taverna.jpg")));

At first line of the Jframe class constructor, that works fine for me

This functions should help you...

bool isThereSpace(String s){
    return s.Contains(" ");
}

I really think your going about this in the wrong manner. Trying to download and parse a +3Mb text file is complete insanity. Why not parse the file on the server side, storing the results viva an ORM to a database(your choice, SQL is good but it also depends on the content key-value data works better on something like CouchDB) then use ajax to parse data on the client end.

Plus, an even better idea would to skip the text file entirely for even better performance if at all possible.

Try this:

sed -i 's/\s*$//' youfile.txt

Another way to do this:

first_value = df['Btime'].values[0]

This way seems to be faster than using .iloc:

In [1]: %timeit -n 1000 df['Btime'].values[20]
5.82 µs ± 142 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [2]: %timeit -n 1000 df['Btime'].iloc[20]
29.2 µs ± 1.28 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Try out this probably it will work

input{
outline-color: #fff //your color
outline-style: none // it depend on you 
}

Just a quick comment: sometimes Maven does not copy the jstl-.jar to the WEB-INF folder even if the pom.xml has the entry for it.

I had to manually copy the JSTL jar to /WEB-INF/lib on the file system. That resolved the problem. The issue may be related to Maven war packaging plugin.

I fully agree with the Key error comments. You could also use the dictionary's get() method as well to avoid the exceptions. This could also be used to give a default path rather than None as shown below.

>>> d = {"a":1, "b":2}
>>> x = d.get("A",None)
>>> print x
None

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

• When I got the error, I tried to Google out the meaning of the expression and I found, this issue occurs when a server changes their HTTPS SSL certificate, and our older version of java doesn’t recognize the root certificate authority (CA).

• If you can access the HTTPS URL in your browser then it is possible to update Java to recognize the root CA.

• In your browser, go to the HTTPS URL that Java could not access. Click on the HTTPS certificate chain (there is lock icon in the Internet Explorer), click on the lock to view the certificate.

• Go to “Details” of the certificate and “Copy to file”. Copy it in Base64 (.cer) format. It will be saved on your Desktop.

• Install the certificate ignoring all the alerts.

• This is how I gathered the certificate information of the URL that I was trying to access.

Now I had to make my java version to know about the certificate so that further it doesn’t refuse to recognize the URL. In this respect I must mention that I googled out that root certificate information stays by default in JDK’s \jre\lib\security location, and the default password to access is: changeit.

To view the cacerts information the following are the procedures to follow:

• Click on Start Button-->Run

• Type cmd. The command prompt opens (you may need to open it as administrator).

• Go to your Java/jreX/bin directory

• Type the following

keytool -list -keystore D:\Java\jdk1.5.0_12\jre\lib\security\cacerts

It gives the list of the current certificates contained within the keystore. It looks something like this:

C:\Documents and Settings\NeelanjanaG>keytool -list -keystore D:\Java\jdk1.5.0_12\jre\lib\security\cacerts

Enter keystore password: changeit

Keystore type: jks

Keystore provider: SUN

Your keystore contains 44 entries

• Now I had to include the previously installed certificate into the cacerts.

• For this the following is the procedure:

keytool –import –noprompt –trustcacerts –alias ALIASNAME -file FILENAME_OF_THE_INSTALLED_CERTIFICATE -keystore PATH_TO_CACERTS_FILE -storepass PASSWORD

If you are using Java 7:

keytool –importcert –trustcacerts –alias ALIASNAME -file PATH_TO_FILENAME_OF_THE_INSTALLED_CERTIFICATE -keystore PATH_TO_CACERTS_FILE -storepass changeit

• It will then add the certificate information into the cacert file.

It is the solution I found for the Exception mentioned above!!

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

Include "B.h" in "A.h". That brings in the declaration of 'B' for the compiler while compiling 'A'.

The first bullet holds in the case of OP.

$3.4.1/7 -

"A name used in the definition of a class X outside of a member function body or nested class definition27) shall be declared in one of the following ways:

— before its use in class X or be a member of a base class of X (10.2), or

— if X is a nested class of class Y (9.7), before the definition of X in Y, or shall be a member of a base class of Y (this lookup applies in turn to Y’s enclosing classes, starting with the innermost enclosing class),28) or

— if X is a local class (9.8) or is a nested class of a local class, before the definition of class X in a block enclosing the definition of class X, or

— if X is a member of namespace N, or is a nested class of a class that is a member of N, or is a local class or a nested class within a local class of a function that is a member of N, before the definition of class X in namespace N or in one of N’s enclosing namespaces."

The solution is already answered here above (long ago).

But the implicit question "why does it work in FF and IE but not in Chrome and Safari" is found in the error text "Not allowed to load local resource": Chrome and Safari seem to use a more strict implementation of sandboxing (for security reasons) than the other two (at this time 2011).

This applies for local access. In a (normal) server environment (apache ...) the file would simply not have been found.

COUNTIF works well for quick difference-checking. And it's easier to remember and simpler to work with than VLOOKUP.

=COUNTIF([Book1]Sheet1!$A:$A, A1) 

will give you a column showing 1 if there's match and zero if there's no match (with the bonus of showing >1 for duplicates within the list itself).

In iOS 6.0 and above, things have changed with the new dequeueReusableHeaderFooterViewWithIdentifier API.

I have written a guide (tested on iOS 9), which can be summarised as such:

1. Subclass UITableViewHeaderFooterView
2. Create Nib with the subclass view, and add 1 container view which contains all other views in the header/footer
3. Register the Nib in viewDidLoad
4. Implement viewForHeaderInSection and use dequeueReusableHeaderFooterViewWithIdentifier to get back the header/footer

As several people here have pointed out, passing the result of Math.random() directly to .string(36) has several problems.

It has poor randomness. The number of characters generated varies, and on average depends on the tricky details of how floating-point numbers work in Javascript. It seems to work if I am trying to generate 11 characters or fewer, but not with more than 11. And it is not flexible. There is no easy way to allow or prohibit certain characters.

I have a compact solution, which doesn't have these problems, for anyone using lodash:

_.range(11).map(i => _.sample("abcdefghijklmnopqrstuvwxyz0123456789")).join('')

If you want to allow certain characters (such as uppercase letters) or prohibit certain characters (like ambiguous characters such as l and 1), modify the string above.

You can use the % character to 'escape' characters that aren't allowed in URLs. See [RFC 1738].

A table of ASCII values on http://www.asciitable.com/.

You can see & is 26 in hexadecimal - so you need M%26M.

If you can't update configuration files but control the code that handles file uploads use HttpContext.Current.Request.GetBufferlessInputStream(true).

The true value for disableMaxRequestLength parameter tells the framework to ignore configured request limits.

Snarky comment: Yes, you can also do it with JQuery. :-)

When you use an async function like

async () => {
    try {
        const response = await fetch(`https://www.reddit.com/r/${subreddit}.json`);
        const json = await response.json();
        setPosts(json.data.children.map(it => it.data));
    } catch (e) {
        console.error(e);
    }
}

it returns a promise and useEffect doesn't expect the callback function to return Promise, rather it expects that nothing is returned or a function is returned.

As a workaround for the warning you can use a self invoking async function.

useEffect(() => {
    (async function() {
        try {
            const response = await fetch(
                `https://www.reddit.com/r/${subreddit}.json`
            );
            const json = await response.json();
            setPosts(json.data.children.map(it => it.data));
        } catch (e) {
            console.error(e);
        }
    })();
}, []);

or to make it more cleaner you could define a function and then call it

useEffect(() => {
    async function fetchData() {
        try {
            const response = await fetch(
                `https://www.reddit.com/r/${subreddit}.json`
            );
            const json = await response.json();
            setPosts(json.data.children.map(it => it.data));
        } catch (e) {
            console.error(e);
        }
    };
    fetchData();
}, []);

the second solution will make it easier to read and will help you write code to cancel previous requests if a new one is fired or save the latest request response in state

I have just made bypass this error by just changing the values of the "length" in the original database to the total of around "1000" by changing its structure, and then exporting the same, to the server. :)

You have to "revert the revert". Depending on you how did the original revert, it may not be as easy as it sounds. Look at the official document on this topic.

---o---o---o---M---x---x---W---x---Y
              /
      ---A---B-------------------C---D

to allow:

---o---o---o---M---x---x-------x-------*
              /                       /
      ---A---B-------------------C---D

But does it all work? Sure it does. You can revert a merge, and from a purely technical angle, git did it very naturally and had no real troubles.
It just considered it a change from "state before merge" to "state after merge", and that was it.
Nothing complicated, nothing odd, nothing really dangerous. Git will do it without even thinking about it.

So from a technical angle, there's nothing wrong with reverting a merge, but from a workflow angle it's something that you generally should try to avoid.

If at all possible, for example, if you find a problem that got merged into the main tree, rather than revert the merge, try really hard to:

• bisect the problem down into the branch you merged, and just fix it,
• or try to revert the individual commit that caused it.

Yes, it's more complex, and no, it's not always going to work (sometimes the answer is: "oops, I really shouldn't have merged it, because it wasn't ready yet, and I really need to undo all of the merge"). So then you really should revert the merge, but when you want to re-do the merge, you now need to do it by reverting the revert.

The answer above is correct. Please be sure that you have a string data in base64 in the data variable without any prefix or stuff like that just raw data.

Here's what I did on the server side (asp.net mvc core):

string path = Path.Combine(folder, fileName);
Byte[] bytes = System.IO.File.ReadAllBytes(path);
string base64 = Convert.ToBase64String(bytes);

On the client side, I did the following code:

const xhr = new XMLHttpRequest();

xhr.open("GET", url);
xhr.setRequestHeader("Content-Type", "text/plain");

xhr.onload = () => {
    var bin = atob(xhr.response);
    var ab = s2ab(bin); // from example above
    var blob = new Blob([ab], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' });

    var link = document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    link.download = 'demo.xlsx';

    document.body.appendChild(link);

    link.click();

    document.body.removeChild(link);
};

xhr.send();

And it works perfectly for me.

Though I wouldn't consider this as a valid answer to OP's question, I'd still emphasize that the best way to deploy Jenkins (and likely most if not all libraries/packages/software) on Ubuntu is to leverage aptitude (or apt-get) management system.

It is documented here: https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu (notice that if you want to use the LTS build, hit on this repo http://pkg.jenkins-ci.org/debian-stable/)

So if by any chance you actually did use this approach, you'd simply do a apt-get upgrade jenkins

If in case trigger("chosen:updated"); doesn't works for you. You can try $('#ddl').trigger('change'); as in my case its work for me.

I had same problem. I just solved it with declaring adapter public before onCreate of class.

PostAdapter postAdapter;

after that

postAdapter = new PostAdapter(getActivity(), posts);
recList.setAdapter(postAdapter);

at last I have called:

@Override
protected void onPostExecute(Void aVoid) {
    super.onPostExecute(aVoid);
    // Display the size of your ArrayList
    Log.i("TAG", "Size : " + posts.size());
    progressBar.setVisibility(View.GONE);
    postAdapter.notifyDataSetChanged();
}

May this will helps you.

In your current window xaml.cs file, call the below code:

var curWnd = Window.GetWindow(this); // passing current window context
curWnd?.Close();

This should do the thing.
It worked for me, hope will do the same for you )

javac only compiles the code. You need to use java command to run the code. The error is because your classpath doesn't contain the class Subclass iwhen you tried to compile it. you need to add them with the -cp variable in javac command

java -cp classpath-entries mainjava arg1 arg2 should run your code with 2 arguments

private void buttonNextForm(object sender, EventArgs e)
{
    NextForm nf = new NextForm();//Object of the form that you want to open
    this.hide();//Hide cirrent form.
    nf.ShowModel();//Display the next form window
    this.Close();//While closing the NextForm, control will come again and will close this form as well
}

That is the timeout to create the connection, NOT a timeout for commands executed over that connection.

See for instance http://www.connectionstrings.com/all-sql-server-connection-string-keywords/ (note that the property is "Connect Timeout" (or "Connection Timeout"), not just "Timeout")

From the comments:

It is not possible to set the command timeout through the connection string. However, the SqlCommand has a CommandTimeout property (derived from DbCommand) where you can set a timeout (in seconds) per command.

Do note that when you loop over query results with Read(), the timeout is reset on every read. The timeout is for each network request, not for the total connection.

they are some needs i can't see to dome thing like Keith or Marcos Placona did instead of just doing

using System;
using System.Windows.Forms;

namespace WFsimulateMouseClick
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            button1_Click(button1, new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 1, 1, 1, 1));

            //by the way
            //button1.PerformClick();
            // and
            //button1_Click(button1, new EventArgs());
            // are the same
        }

        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("clicked");
        }
    }
}

You must define the class before creating an instance of the class. Move the invocation of Something to the end of the script.

You can try to put the cart before the horse and invoke procedures before they are defined, but it will be an ugly hack and you will have to roll your own as defined here:

Make function definition in a python file order independent

You can loop on the chars of string and check using the Char Method IsLetter but you can also do a trick using String method IndexOfAny to search other charaters that are not suppose to be in the string.

As stated before it shouldn't be done using client side Javascript but there's a framework for implementing what you want more securely.

Nodejs is a framework that allows you to code server connections in javascript so have a look into Nodejs and you'll probably learn a bit more about communicating with databases and grabbing data you need.

Remember, if you are inside of private red with some proxy, you must be logout and relogin with an external WIFI for example.

Just to add up on Victor's answer.

I would recommend to add a check to see, if the variable (in his case the long midnight) is higher than 1440. If it is, I would omit the .plusDays(1), otherwise the task will only run the day after tomorrow.

I did it simply like this:

Long time;

final Long tempTime = LocalDateTime.now().until(LocalDate.now().plusDays(1).atTime(7, 0), ChronoUnit.MINUTES);
if (tempTime > 1440) {
    time = LocalDateTime.now().until(LocalDate.now().atTime(7, 0), ChronoUnit.MINUTES);
} else {
    time = tempTime;
}

Use Capture list

Defining a Capture List

Each item in a capture list is a pairing of the weak or unowned keyword with a reference to a class instance (such as self) or a variable initialized with some value (such as delegate = self.delegate!). These pairings are written within a pair of square braces, separated by commas.

Place the capture list before a closure’s parameter list and return type if they are provided:

lazy var someClosure: (Int, String) -> String = {
    [unowned self, weak delegate = self.delegate!] (index: Int, stringToProcess: String) -> String in
    // closure body goes here 
} 

If a closure does not specify a parameter list or return type because they can be inferred from context, place the capture list at the very start of the closure, followed by the in keyword:

lazy var someClosure: Void -> String = {
    [unowned self, weak delegate = self.delegate!] in
    // closure body goes here
}

additional explanations

I set width as max-content and it worked for me.

width: max-content;

The short answer is that --ignore-times does more than its name implies. It ignores both the time and size. In contrast, --size-only does exactly what it says.

The long answer is that rsync has three ways to decide if a file is outdated:

1. Compare the size of source and destination.
2. Compare the timestamp of source and destination.
3. Compare the static checksum of source and destination.

These checks are performed before transferring data. Notably, this means the static checksum is distinct from the stream checksum - the later is computed while transferring data.

By default, rsync uses only 1 and 2. Both 1 and 2 can be acquired together by a single stat, whereas 3 requires reading the entire file (this is independent from reading the file for transfer). Assuming only one modifier is specified, that means the following:

• By using --size-only, only 1 is performed - timestamps and checksum are ignored. A file is copied unless its size is identical on both ends.

• By using --ignore-times, neither of 1, 2 or 3 is performed. A file is always copied.

• By using --checksum, 3 is used in addition to 1, but 2 is not performed. A file is copied unless size and checksum match. The checksum is only computed if size matches.

You can set this at boot by adding the "elevator" parameter to the kernel cmdline (such as in grub.cfg)

Example:

elevator=deadline

This will make "deadline" the default I/O scheduler for all block devices.

If you'd like to query or change the scheduler after the system has booted, or would like to use a different scheduler for a specific block device, I recommend installing and use the tool ioschedset to make this easy.

https://github.com/kata198/ioschedset

If you're on Archlinux it's available in aur:

https://aur.archlinux.org/packages/ioschedset

Some example usage:

# Get i/o scheduler for all block devices
[username@hostname ~]$ io-get-sched
sda:    bfq
sr0:    bfq

# Query available I/O schedulers
[username@hostname ~]$ io-set-sched --list
mq-deadline kyber bfq none

# Set sda to use "kyber"
[username@hostname ~]$ io-set-sched kyber /dev/sda
Must be root to set IO Scheduler. Rerunning under sudo...

[sudo] password for username:
+ Successfully set sda to 'kyber'!

# Get i/o scheduler for all block devices to assert change
[username@hostname ~]$ io-get-sched
sda:    kyber
sr0:    bfq

# Set all block devices to use 'deadline' i/o scheduler
[username@hostname ~]$ io-set-sched deadline
Must be root to set IO Scheduler. Rerunning under sudo...

+ Successfully set sda to 'deadline'!
+ Successfully set sr0 to 'deadline'!

# Get the current block scheduler just for sda
[username@hostname ~]$ io-get-sched sda
sda:    mq-deadline

Usage should be self-explanatory. The tools are standalone and only require bash.

Hope this helps!

EDIT: Disclaimer, these are scripts I wrote.

Consider the below definition in web.xml

<servlet>
    <servlet-name>HelloWorld</servlet-name>
    <servlet-class>TestServlet</servlet-class>
    <init-param>
        <param-name>myprop</param-name>
        <param-value>value</param-value>
    </init-param>
</servlet>

You can see that init-param is defined inside a servlet element. This means it is only available to the servlet under declaration and not to other parts of the web application. If you want this parameter to be available to other parts of the application say a JSP this needs to be explicitly passed to the JSP. For instance passed as request.setAttribute(). This is highly inefficient and difficult to code.

So if you want to get access to global values from anywhere within the application without explicitly passing those values, you need to use Context Init parameters.

Consider the following definition in web.xml

 <web-app>
      <context-param>
           <param-name>myprop</param-name>
           <param-value>value</param-value>
      </context-param>
 </web-app>

This context param is available to all parts of the web application and it can be retrieved from the Context object. For instance, getServletContext().getInitParameter(“dbname”);

From a JSP you can access the context parameter using the application implicit object. For example, application.getAttribute(“dbname”);

You can override ggplots default scales by modifying scale_x_continuous and/or scale_y_continuous. For example:

library(ggplot2)
dat <- data.frame(x = rnorm(100), y = rnorm(100))

ggplot(dat, aes(x,y)) +
  geom_point()

Gives you this:

And overriding the scales can give you something like this:

ggplot(dat, aes(x,y)) +
  geom_point() +
  scale_x_continuous(breaks = round(seq(min(dat$x), max(dat$x), by = 0.5),1)) +
  scale_y_continuous(breaks = round(seq(min(dat$y), max(dat$y), by = 0.5),1))

If you want to simply "zoom" in on a specific part of a plot, look at xlim() and ylim() respectively. Good insight can also be found here to understand the other arguments as well.
