In case you need the [] syntax, useful for "edit forms" when you need to pass parameters like id with the route, you would do something like:

[routerLink]="['edit', business._id]"

As for an "about page" with no parameters like yours,

[routerLink]="/about"

or

[routerLink]=['about']

will do the trick.

I found a solution

File -> Virtual Media Manager -> Removed existing images (note, I removed them only from the registry).

I followed these steps.

http://www.webdesignblog.asia/software/virtualbox-moving-vdi-file-re-linking-guest/#sthash.1QOHeiw5.dpbs

After that I could update the path in the VM settings.

in my case just

const myReducers = combineReducers({
  user: UserReducer
});

const store: any = createStore(
  myReducers,
  applyMiddleware(thunk)
);

shallow(<Login />, { context: { store } });

I've had this issue, adding --recursive to the command will help.

At this point it doesn't quite make sense as you (like me) are only trying to copy a single file down, but it does the trick!

After a bit of trial and error... as mentioned in the possible answers, it turned out to require xfs_growfs rather than resize2fs.

CentOS 7,

fdisk /dev/xvda

Create new primary partition, set type as linux lvm.

n
p
3
t
8e
w

Create a new primary volume and extend the volume group to the new volume.

partprobe
pvcreate /dev/xvda3
vgextend /dev/centos /dev/xvda3

Check the physical volume for free space, extend the logical volume with the free space.

vgdisplay -v
lvextend -l+288 /dev/centos/root

Finally perform an online resize to resize the logical volume, then check the available space.

xfs_growfs /dev/centos/root
df -h

I would say you have an indentation problem, at least as you wrote it here:

while not os.path.exists(file + "_" + str(i) + extension):
   i+=1
   print "Already 2x exists..."
   print "Renaming"
   shutil.copy(path, file + "_" + str(i) + extension)

should be:

while os.path.exists(file + "_" + str(i) + extension):
    i+=1
print "Already 2x exists..."
print "Renaming"
shutil.copy(path, file + "_" + str(i) + extension)

Check this out, please!

Bash 4+ tested - This is the correct way to search for size 0:

find /path/to/dir -size 0 -type f -name "*.xml"

Search for multiple file extensions of size 0:

find /path/to/dir -size 0 -type f \( -iname \*.css -o -iname \*.js \)

Note: If you removed the \( ... \) the results would be all of the files that meet this requirement hence ignoring the size 0.

Just put quotes around the Environment variable (as you have done) :
if "%DevEnvDir%" == "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\"
but it's the way you put opening bracket without a space that is confusing it.

Works for me...

C:\if "%gtk_basepath%" == "C:\Program Files\GtkSharp\2.12\" (echo yes)
yes

Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.

import pickle

class MyUser(object):
    def __init__(self,name):
        self.name = name

user = MyUser('Peter')

print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'

with open(filename,'wb') as file_object:
    file_object.write(serialized)

with open(filename,'rb') as file_object:
    raw_data = file_object.read()

deserialized = pickle.loads(raw_data)


print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)
print("------------")

In my case the problem was that I had called $("#divDialog").removeData(); as part of resetting my forms data within the dialog.

This resulted in me wiping out a data structure named uiDialog which meant that the dialog had to reinitialize.

I replaced .removeData() with more specific deletes and everything started working again.

To check if the value is a double:

private void button1_Click(object sender, EventArgs e)
{

    if (!double.TryParse(textBox1.Text, out var x))
    {
        System.Console.WriteLine("it's not a double ");
        return;
    }
    System.Console.WriteLine("it's a double ");
}

Using EnumerateFiles to get files in nested directories. Use AllDirectories to recurse throught directories.

using System;
using System.IO;

class Program
{
    static void Main()
    {
    // Call EnumerateFiles in a foreach-loop.
    foreach (string file in Directory.EnumerateFiles(@"c:\files",
        "*.xml",
        SearchOption.AllDirectories))
    {
        // Display file path.
        Console.WriteLine(file);
    }
    }
}

I have added slashes before inserting into database so on the time of fetching i removed slashes again stripslashes() and it works for me. I am sharing the code which works for me.

How i inserted into mysql db (blob type)

$db = mysqli_connect("localhost","root","","dName"); 
$image = addslashes(file_get_contents($_FILES['images']['tmp_name']));
$query = "INSERT INTO student_img (id,image) VALUES('','$image')";  
$query = mysqli_query($db, $query);

Now to access the image

$sqlQuery = "SELECT * FROM student_img WHERE id = $stid";
$rs = $db->query($sqlQuery);
$result=mysqli_fetch_array($rs);
echo '<img src="data:image/jpeg;base64,'.base64_encode( stripslashes($result['image']) ).'"/>';

Hope it will help someone

Thanks.

I will suggest something totally different, we used it at work for many years ago on real computers and it worked perfect.

Boot both old and new machine on linux rescue Cd.

read the disk from one, and write it down to the other one, block by block, effectively copying the dist over the network.

You have to play around a little bit with the command line, but it worked so well that both machine complained about IP-conflict when they both booted :-) :-)

cat /dev/sda | ssh user@othermachine cat - > /dev/sda

select directory_path from dba_directories where upper(directory_name) = 'CSVDIR'

Well Facebook has undergone MANY many changes and it wasn't originally designed to be efficient. It was designed to do it's job. I have absolutely no idea what the code looks like and you probably won't find much info about it (for obvious security and copyright reasons), but just take a look at the API. Look at how often it changes and how much of it doesn't work properly, anymore, or at all.

I think the biggest ace up their sleeve is the Hiphop. http://developers.facebook.com/blog/post/358 You can use HipHop yourself: https://github.com/facebook/hiphop-php/wiki

But if you ask me it's a very ambitious and probably time wasting task. Hiphop only supports so much, it can't simply convert everything to C++. So what does this tell us? Well, it tells us that Facebook is NOT fully taking advantage of the PHP language. It's not using the latest 5.3 and I'm willing to bet there's still a lot that is PHP 4 compatible. Otherwise, they couldn't use HipHop. HipHop IS A GOOD IDEA and needs to grow and expand, but in it's current state it's not really useful for that many people who are building NEW PHP apps.

There's also PHP to JAVA via things like Resin/Quercus. Again, it doesn't support everything...

Another thing to note is that if you use any non-standard PHP module, you aren't going to be able to convert that code to C++ or Java either. However...Let's take a look at PHP modules. They are ARE compiled in C++. So if you can build PHP modules that do things (like parse XML, etc.) then you are basically (minus some interaction) working at the same speed. Of course you can't just make a PHP module for every possible need and your entire app because you would have to recompile and it would be much more difficult to code, etc.

However...There are some handy PHP modules that can help with speed concerns. Though at the end of the day, we have this awesome thing known as "the cloud" and with it, we can scale our applications (PHP included) so it doesn't matter as much anymore. Hardware is becoming cheaper and cheaper. Amazon just lowered it's prices (again) speaking of.

So as long as you code your PHP app around the idea that it will need to one day scale...Then I think you're fine and I'm not really sure I'd even look at Facebook and what they did because when they did it, it was a completely different world and now trying to hold up that infrastructure and maintain it...Well, you get things like HipHop.

Now how is HipHop going to help you? It won't. It can't. You're starting fresh, you can use PHP 5.3. I'd highly recommend looking into PHP 5.3 frameworks and all the new benefits that PHP 5.3 brings to the table along with the SPL libraries and also think about your database too. You're most likely serving up content from a database, so check out MongoDB and other types of databases that are schema-less and document-oriented. They are much much faster and better for the most "common" type of web site/app.

Look at NEW companies like Foursquare and Smugmug and some other companies that are utilizing NEW technology and HOW they are using it. For as successful as Facebook is, I honestly would not look at them for "how" to build an efficient web site/app. I'm not saying they don't have very (very) talented people that work there that are solving (their) problems creatively...I'm also not saying that Facebook isn't a great idea in general and that it's not successful and that you shouldn't get ideas from it....I'm just saying that if you could view their entire source code, you probably wouldn't benefit from it.

You should use Android NDK to develop performance-critical portions of your apps in native code. See Android NDK.

Anyway i don't think it is the right way to develop an entire application.

I see only one case that you would allow exposure to your internal members to another assembly and that is for testing purposes.

Saying that there is a way to allow "Friend" assemblies access to internals:

In the AssemblyInfo.cs file of the project you add a line for each assembly.

[assembly: InternalsVisibleTo("name of assembly here")]

this info is available here.

Hope this helps.

For me I had issues with history and location... As the accepted answer using window before history and location (i.e) window.history and window.location solved mine

For me after extensive debugging the fix was a simple missing throw; statement in the catch after the rollback. Without it this ugly error message is what you end up with.

begin catch
    if @@trancount > 0 rollback transaction;
    throw; --allows capture of useful info when an exception happens within the transaction
end catch

All relative URLs in the HTML page generated by the JSP file are relative to the current request URL (the URL as you see in the browser address bar) and not to the location of the JSP file in the server side as you seem to expect. It's namely the webbrowser who has to download those resources individually by URL, not the webserver who has to include them from disk somehow.

Apart from changing the relative URLs to make them relative to the URL of the servlet instead of the location of the JSP file, another way to fix this problem is to make them relative to the domain root (i.e. start with a /). This way you don't need to worry about changing the relative paths once again when you change the URL of the servlet.

<head>
    <link rel="stylesheet" href="/context/css/default.css" />
    <script src="/context/js/default.js"></script>
</head>
<body>
    <img src="/context/img/logo.png" />
    <a href="/context/page.jsp">link</a>
    <form action="/context/servlet"><input type="submit" /></form>
</body>

However, you would probably like not to hardcode the context path. Very reasonable. You can obtain the context path in EL by ${pageContext.request.contextPath}.

<head>
    <link rel="stylesheet" href="${pageContext.request.contextPath}/css/default.css" />
    <script src="${pageContext.request.contextPath}/js/default.js"></script>
</head>
<body>
    <img src="${pageContext.request.contextPath}/img/logo.png" />
    <a href="${pageContext.request.contextPath}/page.jsp">link</a>
    <form action="${pageContext.request.contextPath}/servlet"><input type="submit" /></form>
</body>

(which can easily be shortened by <c:set var="root" value="${pageContext.request.contextPath}" /> and used as ${root} elsewhere)

Or, if you don't fear unreadable XML and broken XML syntax highlighting, use JSTL <c:url>:

<head>
    <link rel="stylesheet" href="<c:url value="/css/default.css" />" />
    <script src="<c:url value="/js/default.js" />"></script>
</head>
<body>
    <img src="<c:url value="/img/logo.png" />" />
    <a href="<c:url value="/page.jsp" />">link</a>
    <form action="<c:url value="/servlet" />"><input type="submit" /></form>
</body>

Either way, this is in turn pretty cumbersome if you have a lot of relative URLs. For that you can use the <base> tag. All relative URL's will instantly become relative to it. It has however to start with the scheme (http://, https://, etc). There's no neat way to obtain the base context path in plain EL, so we need a little help of JSTL here.

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<c:set var="req" value="${pageContext.request}" />
<c:set var="uri" value="${req.requestURI}" />
<c:set var="url">${req.requestURL}</c:set>
...
<head>
    <base href="${fn:substring(url, 0, fn:length(url) - fn:length(uri))}${req.contextPath}/" />
    <link rel="stylesheet" href="css/default.css" />
    <script src="js/default.js"></script>
</head>
<body>
    <img src="img/logo.png" />
    <a href="page.jsp">link</a>
    <form action="servlet"><input type="submit" /></form>
</body>

This has in turn (again) some caveats. Anchors (the #identifier URL's) will become relative to the base path as well! You would like to make it relative to the request URL (URI) instead. So, change like

<a href="#identifier">jump</a>

to

<a href="${uri}#identifier">jump</a>

Each way has its own pros and cons. It's up to you which to choose. At least, you should now understand how this problem is caused and how to solve it :)

• Is it recommended to use the <base> html tag?

Assuming that your profile in ~/aws/config is using the region (instead of AZ as per your original question); the other cause is your client's inability to connect to s3.us-east-1.amazonaws.com. In my case, I was unable to resolve that DNS name due to an error in my network configuration. Fixing the DNS issue solved my problem.

You may find the HitchHiker's Guide to Packaging helpful, even though it is incomplete. I'd start with the Quick Start tutorial. Try also just browsing through Python packages on the Python Package Index. Just download the tarball, unpack it, and have a look at the setup.py file. Or even better, only bother looking through packages that list a public source code repository such as one hosted on GitHub or BitBucket. You're bound to run into one on the front page.

My final suggestion is to just go for it and try making one; don't be afraid to fail. I really didn't understand it until I started making them myself. It's trivial to create a new package on PyPI and just as easy to remove it. So, create a dummy package and play around.

I would point out that (functionally) there's a BIG difference between cycles and/or multiple paths in the SCHEMA and the DATA. While cycles and perhaps multipaths in the DATA could certainly complicated processing and cause performance problems (cost of "properly" handling), the cost of these characteristics in the schema should be close to zero.

Since most apparent cycles in RDBs occur in hierarchical structures (org chart, part, subpart, etc.) it is unfortunate that SQL Server assumes the worst; i.e., schema cycle == data cycle. In fact, if you're using RI constraints you can't actually build a cycle in the data!

I suspect the multipath problem is similar; i.e., multiple paths in the schema don't necessarily imply multiple paths in the data, but I have less experience with the multipath problem.

Of course if SQL Server did allow cycles it'd still be subject to a depth of 32, but that's probably adequate for most cases. (Too bad that's not a database setting however!)

"Instead of Delete" triggers don't work either. The second time a table is visited, the trigger is ignored. So, if you really want to simulate a cascade you'll have to use stored procedures in the presence of cycles. The Instead-of-Delete-Trigger would work for multipath cases however.

Celko suggests a "better" way to represent hierarchies that doesn't introduce cycles, but there are tradeoffs.

As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

You can use duplicated to do this very quickly.

test[!duplicated(test$id),]

Benchmarks, for the speed freaks:

ju <- function() test[!duplicated(test$id),]
gs1 <- function() do.call(rbind, lapply(split(test, test$id), head, 1))
gs2 <- function() do.call(rbind, lapply(split(test, test$id), `[`, 1, ))
jply <- function() ddply(test,.(id),function(x) head(x,1))
jdt <- function() {
  testd <- as.data.table(test)
  setkey(testd,id)
  # Initial solution (slow)
  # testd[,lapply(.SD,function(x) head(x,1)),by = key(testd)]
  # Faster options :
  testd[!duplicated(id)]               # (1)
  # testd[, .SD[1L], by=key(testd)]    # (2)
  # testd[J(unique(id)),mult="first"]  # (3)
  # testd[ testd[,.I[1L],by=id] ]      # (4) needs v1.8.3. Allows 2nd, 3rd etc
}

library(plyr)
library(data.table)
library(rbenchmark)

# sample data
set.seed(21)
test <- data.frame(id=sample(1e3, 1e5, TRUE), string=sample(LETTERS, 1e5, TRUE))
test <- test[order(test$id), ]

benchmark(ju(), gs1(), gs2(), jply(), jdt(),
    replications=5, order="relative")[,1:6]
#     test replications elapsed relative user.self sys.self
# 1   ju()            5    0.03    1.000      0.03     0.00
# 5  jdt()            5    0.03    1.000      0.03     0.00
# 3  gs2()            5    3.49  116.333      2.87     0.58
# 2  gs1()            5    3.58  119.333      3.00     0.58
# 4 jply()            5    3.69  123.000      3.11     0.51

Let's try that again, but with just the contenders from the first heat and with more data and more replications.

set.seed(21)
test <- data.frame(id=sample(1e4, 1e6, TRUE), string=sample(LETTERS, 1e6, TRUE))
test <- test[order(test$id), ]
benchmark(ju(), jdt(), order="relative")[,1:6]
#    test replications elapsed relative user.self sys.self
# 1  ju()          100    5.48    1.000      4.44     1.00
# 2 jdt()          100    6.92    1.263      5.70     1.15

You can use AWS API or console UI to create an AMI(Amazon Machine Image) of your running instance. You can specify to reboot the instance when create your AMI. Then you can use AWS API or console UI to launch more instances with the AMI you created.

If you are using CentOS or another Linux flavour then just do Ctrl+R at the prompt and type git.

If you keep hitting Ctrl+R this will do a reverse search through your history for commands that start with git

If you are accessing a plain HTML form, it has to be submitted to the server via a submit button (or via javascript post). This usually means that your form definition will look like this (I'm going off of memory, make sure you check the html elements are correct):

<form method="POST" action="page.aspx">

<input id="customerName" name="customerName" type="Text" />
<input id="customerPhone" name="customerPhone" type="Text" />
<input value="Save" type="Submit" />

</form>

You should be able to access the customerName and customerPhone data like this:

string n = String.Format("{0}", Request.Form["customerName"]);

If you have method="GET" in the form (not recommended, it messes up your URL space), you will have to access the form data like this:

string n = String.Format("{0}", Request.QueryString["customerName"]);

This of course will only work if the form was 'Posted', 'Submitted', or done via a 'Postback'. (i.e. somebody clicked the 'Save' button, or this was done programatically via javascript.)

Also, keep in mind that accessing these elements in this manner can only be done when you are not using server controls (i.e. runat="server"), with server controls the id and name are different.

Obligatory: This is a hack: CSS isn't the right place to do this, but in some situations - eg, you have a third party library in an iframe that can only be customized by CSS - this kind of hack is the only option.

You can replace text through CSS. Let's replace a green button that has the word 'hello' with a red button that has the word 'goodbye', using CSS.

Before:

After:

See http://jsfiddle.net/ZBj2m/274/ for a live demo:

Here's our green button:

<button>Hello</button>

button {
  background-color: green;
  color: black;
  padding: 5px;
}

Now let's hide the original element, but add another block element afterwards:

button {
  visibility: hidden;
}
button:after {
  content:'goodbye'; 
  visibility: visible;
  display: block;
  position: absolute;
  background-color: red;
  padding: 5px;
  top: 2px;
}

Note:

• We explicitly need to mark this as a block element, 'after' elements are inline by default
• We need to compensate for the original element by adjusting the pseudo-element's position.
• We must hide the original element and display the pseudo element using visibility. Note display: none on the original element doesn't work.

    $user->fill($data);
    $this->validate($user->toArray(), $id);
    $user->save();
    return $user;
}


public function validate($data, $id=null) {
    $rules = User::$rules;
    if ($id !== null) {
        $rules['username'] .= ",$id";
        $rules['email'] .= ",$id";
    }
    $validation = Validator::make($data, $rules);
    if ($validation->fails()) {
        throw new ValidationException($validation);
    }
    return true;
}

is what I did, based on the accepted answer above.

EDIT: With Form Requests, everything is made simpler:

<?php namespace App\Http\Requests;

class UpdateUserRequest extends Request
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name' => 'required|unique:users,username,'.$this->id,
            'email' => 'required|unique:users,email,'.$this->id,
        ];
    }
}

You just need to pass the UpdateUserRequest to your update method, and be sure to POST the model id.

It's because you're calling doGet() without actually implementing doGet(). It's the default implementation of doGet() that throws the error saying the method is not supported.

you need to put a dot between the class like

class="column.wrapper">

I had to use

powershell.AddCommand("Get-ADPermission");
powershell.AddParameter("Identity", "complete id path with OU in it");

to get past this error

Considering filter:expression is a Microsoft extension to CSS, so it will only work in Internet Explorer. If you want to grey it out, I would recommend that you set it's opacity to 50% using a bit of javascript.

http://lyxus.net/mv would be a good place to start, because it discusses an opacity script that works with Firefox, Safari, KHTML, Internet Explorer and CSS3 capable browsers.

You might also want to give it a grey border.

Before answering, let's add some background, explaining what this HEAD is.

First of all what is HEAD?

HEAD is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD at any given time (excluding git worktree).

The content of HEAD is stored inside .git/HEAD and it contains the 40 bytes SHA-1 of the current commit.

detached HEAD

If you are not on the latest commit - meaning that HEAD is pointing to a prior commit in history it's called detached HEAD.

On the command line, it will look like this - SHA-1 instead of the branch name since the HEAD is not pointing to the tip of the current branch:

A few options on how to recover from a detached HEAD:

git checkout

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits to go back

This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.

# Checkout a given commit.
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>

# Create a new branch forked to the given commit
git checkout -b <branch name>

git reflog

You can always use the reflog as well.
git reflog will display any change which updated the HEAD and checking out the desired reflog entry will set the HEAD back to this commit.

Every time the HEAD is modified there will be a new entry in the reflog

git reflog
git checkout HEAD@{...}

This will get you back to your desired commit

git reset --hard <commit_id>

"Move" your HEAD back to the desired commit.

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.

• Note: (Since Git 2.7) you can also use the git rebase --no-autostash as well.

git revert <sha-1>

"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.

# Add a new commit with the undo of the original one.
# The <sha-1> can be any commit(s) or commit range
git revert <sha-1>

This schema illustrates which command does what.
As you can see there, reset && checkout modify the HEAD.

long d1Ms=asa.getTime();   
long d2Ms=asa2.getTime();   
long minute = Math.abs((d1Ms-d2Ms)/60000);   
int Hours = (int)minute/60;     
int Minutes = (int)minute%60;     
stUr.setText(Hours+":"+Minutes); 

I could "automate" it with a call to:

def __fix_io_encoding(last_resort_default='UTF-8'):
  import sys
  if [x for x in (sys.stdin,sys.stdout,sys.stderr) if x.encoding is None] :
      import os
      defEnc = None
      if defEnc is None :
        try:
          import locale
          defEnc = locale.getpreferredencoding()
        except: pass
      if defEnc is None :
        try: defEnc = sys.getfilesystemencoding()
        except: pass
      if defEnc is None :
        try: defEnc = sys.stdin.encoding
        except: pass
      if defEnc is None :
        defEnc = last_resort_default
      os.environ['PYTHONIOENCODING'] = os.environ.get("PYTHONIOENCODING",defEnc)
      os.execvpe(sys.argv[0],sys.argv,os.environ)
__fix_io_encoding() ; del __fix_io_encoding

Yes, it's possible to get an infinite loop here if this "setenv" fails.

Open your build.gradle file and make sure you have versionCode and versionName inside defaultConfig element. If not, add them. Refer to this link for more details.

The '\r' stands for "Carriage Return" - it's a holdover from the days of typewriters and really old printers. The best example is in Windows and other DOSsy OSes, where a newline is given as "\r\n". These are the instructions sent to an old printer to start a new line: first move the print head back to the beginning, then go down one.

Different OSes will use other newline sequences. Linux and OSX just use '\n'. Older Mac OSes just use '\r'. Wikipedia has a more complete list, but those are the important ones.

Hope this helps!

PS: As for why you get that weird output... Perhaps the console is moving the "cursor" back to the beginning of the line, and then overwriting the first bit with spaces or summat.

I've seen this error in a similar situation to mentioned in Joe's answer:

description: Too high 5xx responses rate: {{ .Value }} > 0.05

We have a colon in description value. So, the problem is in missing quotes around description value. It can be resolved by adding quotes:

description: 'Too high 5xx responses rate: {{ .Value }} > 0.05'

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

It's ugly, but I achieved a semblance of this like so:

Dockerfile:

FROM foo
COPY ./m2/ /root/.m2
RUN stuff

imageBuild.sh:

docker build . -t barImage
container="$(docker run -d barImage)"
rm -rf ./m2
docker cp "$container:/root/.m2" ./m2
docker rm -f "$container"

I have a java build that downloads the universe into /root/.m2, and did so every single time. imageBuild.sh copies the contents of that folder onto the host after the build, and Dockerfile copies them back into the image for the next build.

This is something like how a volume would work (i.e. it persists between builds).

I have found that %CD% gives the path the script was called from and not the path of the script, however, %~dp0 will give the path of the script itself.

If someone looking for a way to display decimal places even if it ends with ".00", use this:

String.Format("{0:n1}", value)

I had the same problem and it was due to the end of line. I had copied from another document. I put everythng on the same line, then split them again and it worked.

Here is the tutorial :- http://javatechig.com/android/installing-android-studio and http://codearetoy.wordpress.com/2010/12/23/jdk-not-found-on-installing-android-sdk/

Adding a system variable JDK_HOME with value c:\Program Files\Java\jdk1.7.0_21\ worked for me. The latest Java release can be downloaded here. Additionally, make sure the variable JAVA_HOME is also set with the above location.

Please note that the above location is my java location. Please post your location in the path

Use a script like the following to execute the rest or part of the script under another user:

#!/bin/sh

id

exec sudo -u transmission /bin/sh - << eof

id

eof

spans are by default displayed inline, which means they don't have a height and width.

Try adding a display: block to your span.

AFAIK it's not possible with plain CSS,
but you can do a pretty expensive jQuery operation like:

jsBin demo

$('*').css('fontSize', function(i, fs){
  if(parseInt(fs, 10) < 12 ) return this.style.fontSize = "12px";
});

_{Instead of using the Global Selector * I'd suggest you (if possible) to be more specific with your selectors.}

On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7

Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)

If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:

tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install        <-- sudo is required.

This might take a while

you can disable or set date and time for log setting.

This error message can also be caused by SELinux. Check if SELinux is enabled with getenforce

You need to adjust SELinux to use your port and restart.

I.E.

Bubble Sort is not online (it cannot sort a stream of inputs without knowing how many items there will be) because it does not really keep track of a global maximum of the sorted elements. When an item is inserted you will need to start the bubbling from the very beginning

Here is a work around but not always a great one, depending on how much you scale it. Explanation can be found here: https://www.geekgoddess.com/how-to-resize-the-google-nocaptcha-recaptcha/

.g-recaptcha {
    transform:scale(0.77);

UPDATE: Google has added support for a smaller size via a parameter. Have a look at the docs - https://developers.google.com/recaptcha/docs/display#render_param

I know it's not exactly what you are looking for, but maybe it'll help you.

You can try use a jQuery selector :contains(), add a class and then do a normal style for a class.

Nc is a link to nmap-ncat.

It would be nice to use nmap-ncat in your puppet, because NC is a virtual name of nmap-ncat.

Puppet cannot understand the links/virtualnames

your puppet should be:

package {
  'nmap-ncat':
    ensure => installed;
}

Here is the example i have tried and it is working for me:

Create the XML file SoapRequestFile.xml

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
       <soapenv:Header/>
       <soapenv:Body>

          </tem:GetConversionRate>
       </soapenv:Body>
    </soapenv:Envelope>

        }

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

Here's a practical example (build a dataset from your current location):

$ds = new-object System.Data.DataSet
$ds.Tables.Add("tblTest")
[void]$ds.Tables["tblTest"].Columns.Add("Name",[string])
[void]$ds.Tables["tblTest"].Columns.Add("Path",[string])

dir | foreach {
    $dr = $ds.Tables["tblTest"].NewRow()
    $dr["Name"] = $_.name
    $dr["Path"] = $_.fullname
    $ds.Tables["tblTest"].Rows.Add($dr)
}


$ds.Tables["tblTest"]

$ds.Tables["tblTest"] is an object that you can manipulate just like any other Powershell object:

$ds.Tables["tblTest"] | foreach {
    write-host 'Name value is : $_.name
    write-host 'Path value is : $_.path
}

You can also set a default value for the variable, so you don't need to use two "[", which amounts to two processes ("[" is actually a program) instead of one.

It goes by this syntax: ${VARIABLE:-default}.

The whole thing has to be thought in such a way that this "default" value is something distinct from a "valid" value/content.

If that's not possible for some reason you probably need to add a step like checking if there's a value at all, along the lines of "if [ -z $VARIABLE ] ; then echo "the variable needs to be filled"", or "if [ ! -z $VARIABLE ] ; then #everything is fine, proceed with the rest of the script".

You are just missing something in your method:

public void PrinterSetup(string printer)
{
   if (printer == "jupiter") 
   {
      Process.Start("BLAH BLAH CODE TO ADD PRINTER VIA WINDOWS EXEC"");
   }
}

Just add string and you'll be fine.

Two things to keep in mind Content-Type and the Encoding

1) What if the file is css

if (/.(css)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'text/css'}); 
  res.write(data, 'utf8');
} 

2) What if the file is jpg/png

if (/.(jpg)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'image/jpg'});
  res.end(data,'Base64');
}

Above one is just a sample code to explain the answer and not the exact code pattern.

There are a number of workarounds for this issue which involve word-spacing or font size but this article suggests removing the margin with a right margin of -4px;

http://designshack.net/articles/css/whats-the-deal-with-display-inline-block/

You can simply use raw html tags like

foo <font color='red'>bar</font> foo

Be aware that this will not survive a conversion of the notebook to latex.

As there are some complaints about the deprecation of the proposed solution. They are totally valid and Scott has already answered the question with a more recent, i.e. CSS based approach. Nevertheless, this answer shows some general approach to use html tags within IPython to style markdown cell content beyond the available pure markdown capabilities.

Fixed positioning is supposed to define everything in relation to the viewport, so position:fixed is always going to do that. Try using position:relative on the child div instead. (I realize you might need the fixed positioning for other reasons, but if so - you can't really make the width match it's parent with out JS without inherit)

we can write the UTF-8 encoded file with java using use PrintWriter to write UTF-8 encoded xml

Or Click here

PrintWriter out1 = new PrintWriter(new File("C:\\abc.xml"), "UTF-8");

With moment you can parse the date string you have:

var dt = moment(myDate.date, "YYYY-MM-DD HH:mm:ss")

That's for UTC, you'll have to convert the time zone from that point if you so desire.

Then you can get the day of the week:

dt.format('dddd');

This can be achieved using dplyr package, which is available in CRAN. The simple way to achieve this:

1. Install dplyr package.
2. Run the below code

library(dplyr) 

df<- select(filter(dat,name=='tom'| name=='Lynn'), c('days','name))

Explanation:

So, once we’ve downloaded dplyr, we create a new data frame by using two different functions from this package:

filter: the first argument is the data frame; the second argument is the condition by which we want it subsetted. The result is the entire data frame with only the rows we wanted. select: the first argument is the data frame; the second argument is the names of the columns we want selected from it. We don’t have to use the names() function, and we don’t even have to use quotation marks. We simply list the column names as objects.

Create mysql connection with following parameter. "'raise_on_warnings': False". It will ignore the warning. e.g.

config = {'user': 'user','password': 'passwd','host': 'localhost','database': 'db',   'raise_on_warnings': False,}
cnx = mysql.connector.connect(**config)

Try this:

new Date().toLocaleFormat("%x");

All formats for this function can be found here: http://pubs.opengroup.org/onlinepubs/007908799/xsh/strftime.html

Your code alerts the current value of the dropdown for me, showing that it has properly pushed into the array.

Are you wanting to keep old values and append? You're recreating the array each time, meaning that the old value gets clobbered.

Here's some updated code:

var myarray = [];
$("#test").click(function() {
    myarray.push($("#drop").val());
    alert(myarray);
});

jsFiddle

the easiest and safest way is to use something like this:

var waitForJQuery = setInterval(function () {
    if (typeof $ != 'undefined') {

        // place your code here.

        clearInterval(waitForJQuery);
    }
}, 10);

And you can combine same events/functions in this way:

$("table.planning_grid").on({
    mouseenter: function() {
        // Handle mouseenter...
    },
    mouseleave: function() {
        // Handle mouseleave...
    },
    'click blur paste' : function() {
        // Handle click...
    }
}, "input");

It could also be done without a visual client with the following small script.

$ cat ~/bin/pdel

#!/bin/sh

#Todo: add error handling

( p4 -c $1 client -o | perl -pne 's/\blocked\s//' | p4 -c $1  client -i ) && p4 client -d $1

you can use

empty($result) 

to check if the main array is empty or not.

But since you have a SimpleXMLElement object, you need to query the object if it is empty or not. See http://www.php.net/manual/en/simplexmlelement.count.php

ex:

if (empty($result) || !isset($result['Tags'])) {
    return false;
}
if ( !($result['Tags'] instanceof SimpleXMLElement)) {
    return false;
}
return ($result['Tags']->count());

Very Late Answer but I will highlight some point as I had to deal with it years ago setting up my IIS site across network

1. Both your machines should be connected to the same network (same wireless network is fine)
2. Access your remote machine via IP 168.192.x.x or via http://his-pc-name (do not forget the http part)
3. This will server the default IIS page on the remote machine (same that is served through localhost). If you want to server another site, [you have to make that default] first1.

Make sure your IIS is working fine on remote machine by checking localhost which should served the default site. Also make sure your firewall is configured to allow connection via port 80 or you can just disable firewall for the time being for testing purposes.

In Swift 3 and 4

var array = ["a", "b", "c", "d", "e", "f"]

for (index, element) in array.enumerated().reversed() {
    array.remove(at: index)
}

From Swift 4.2 you can use more advanced approach(faster and memory efficient)

array.removeAll(where: { $0 == "c" })

instead of

array = array.filter { !$0.hasPrefix("c") }

Here's a simple wrapper for steven's answer. This function doesn't do repeated runs/averaging, just saves you from having to repeat the timing code everywhere :)

'''function which prints the wall time it takes to execute the given command'''
def time_func(func, *args): #*args can take 0 or more 
  import time
  start_time = time.time()
  func(*args)
  end_time = time.time()
  print("it took this long to run: {}".format(end_time-start_time))

To replace all spaces :

UPDATE `table` SET `col_name` = REPLACE(`col_name`, ' ', '')

To remove all tabs characters :

UPDATE `table` SET `col_name` = REPLACE(`col_name`, '\t', '' )

To remove all new line characters :

UPDATE `table` SET `col_name` = REPLACE(`col_name`, '\n', '')

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace

To remove first and last space(s) of column :

var iframe = $('iframe'); // or some other selector to get the iframe
$('[tokenid=' + token + ']', iframe.contents()).addClass('border');

Also note that if the src of this iframe is pointing to a different domain, due to security reasons, you will not be able to access the contents of this iframe in javascript.

You can get the DOM element and set disabled attribute to true/false.

If you use vue framework,here is a very easy demo.

  let vm = new Vue({
        el: "#app",
        data() {
            return { flag: true }
        },
        computed: {
            btnText() {
                return this.flag ? "Enable" : "Disable";
            }
        }
    })

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">
    <input type="text" value="something" :disabled="flag" />
    <input type="button" :value="btnText" @click="flag=!flag">

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

The most recent and in my opinion preferred approach is the f-string:

''.join(f'{i:02x}' for i in [1, 15, 255])

Format options

The old format style was the %-syntax:

['%02x'%i for i in [1, 15, 255]]

The more modern approach is the .format method:

 ['{:02x}'.format(i) for i in [1, 15, 255]]

More recently, from python 3.6 upwards we were treated to the f-string syntax:

[f'{i:02x}' for i in [1, 15, 255]]

Format syntax

Note that the f'{i:02x}' works as follows.

• The first part before : is the input or variable to format.
• The x indicates that the string should be hex. f'{100:02x}' is '64' and f'{100:02d}' is '1001'.
• The 02 indicates that the string should be left-filled with 0's to length 2. f'{100:02x}' is '64' and f'{100:30x}' is ' 64'.

This is an example of "if else" with actions.

>>> def fun(num):
    print 'This is %d' % num
>>> fun(10) if 10 > 0 else fun(2)
this is 10
OR
>>> fun(10) if 10 < 0 else 1
1

In Python you can iterate over the list itself:

for item in my_list:
   #do something with item

or to use indices you can use xrange():

for i in xrange(1,len(my_list)):    #as indexes start at zero so you 
                                    #may have to use xrange(len(my_list))
    #do something here my_list[i]

There's another built-in function called enumerate(), which returns both item and index:

for index,item in enumerate(my_list):
    # do something here

examples:

In [117]: my_lis=list('foobar')

In [118]: my_lis
Out[118]: ['f', 'o', 'o', 'b', 'a', 'r']

In [119]: for item in my_lis:
    print item
   .....:     
f
o
o
b
a
r

In [120]: for i in xrange(len(my_lis)):
    print my_lis[i]
   .....:     
f
o
o
b
a
r

In [122]: for index,item in enumerate(my_lis):
    print index,'-->',item
   .....:     
0 --> f
1 --> o
2 --> o
3 --> b
4 --> a
5 --> r

To check array is null:

int arr[] = null;
if (arr == null) {
 System.out.println("array is null");
}

To check array is empty:

arr = new int[0];
if (arr.length == 0) {
 System.out.println("array is empty");
}

I'm just going to provide this answer as an alternative @IHeartAndroid's recursive algorithm for discovering all child Views in a view hierarchy. Note that at the time of this writing, the recursive solution is flawed in that it will contains duplicates in its result.

For those who have trouble wrapping their head around recursion, here's a non-recursive alternative. You get bonus points for realizing this is also a breadth-first search alternative to the depth-first approach of the recursive solution.

private List<View> getAllChildrenBFS(View v) {
    List<View> visited = new ArrayList<View>();
    List<View> unvisited = new ArrayList<View>();
    unvisited.add(v);

    while (!unvisited.isEmpty()) {
        View child = unvisited.remove(0);
        visited.add(child);
        if (!(child instanceof ViewGroup)) continue;
        ViewGroup group = (ViewGroup) child;
        final int childCount = group.getChildCount();
        for (int i=0; i<childCount; i++) unvisited.add(group.getChildAt(i));
    }

    return visited;
}

A couple of quick tests (nothing formal) suggest this alternative is also faster, although that has most likely to do with the number of new ArrayList instances the other answer creates. Also, results may vary based on how vertical/horizontal the view hierarchy is.

This is working Current Location with zoom for Google Map V2

 double lat= location.getLatitude();
 double lng = location.getLongitude();
 LatLng ll = new LatLng(lat, lng);
 googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(ll, 20));

Usually not with grep, but rather with sed -i 's/string_to_find/another_string/g' or perl -i.bak -pe 's/string_to_find/another_string/g'.

SELECT CAST(CONVERT(datetime,'2009-06-15 23:01:00') as float)

I tested all the answers about this topic. And nothing worked here… but I found another solution.

Go to pom -> overview and add these to your properties:

Name: “maven.compiler.target” Value: “1.8”

and

Name: “maven.compiler.source” Value: “1.8”

Now do a maven update.

Based off this answer from Lucas Cerro I calculated the dimensions using the ratios in the Android docs, using the baseline in the answer. I hope this helps someone else coming to this post!

• xxxlarge (xxxhdpi): 1280x1920 (4.0x)
• xxlarge (xxhdpi): 960x1440 (3.0x)
• xlarge (xhdpi): 640x960 (2.0x)
• large (hdpi): 480x800 (1.5x)
• medium (mdpi): 320x480 (1.0x baseline)
• small (ldpi): 240x320 (0.75x) 

No you don't need to call the base destructor, a base destructor is always called for you by the derived destructor. Please see my related answer here for order of destruction.

To understand why you want a virtual destructor in the base class, please see the code below:

class B
{
public:
    virtual ~B()
    {
        cout<<"B destructor"<<endl;
    }
};


class D : public B
{
public:
    virtual ~D()
    {
        cout<<"D destructor"<<endl;
    }
};

When you do:

B *pD = new D();
delete pD;

Then if you did not have a virtual destructor in B, only ~B() would be called. But since you have a virtual destructor, first ~D() will be called, then ~B().

ExcelMapper is an open source tool (http://code.google.com/p/excelmapper/) that can be used to read Excel worksheets as Strongly Typed Objects. It supports both xls and xlsx formats.

You can even use this one. worked well for me

$("#registerform").attr("action", "register.php?btnsubmit=Save") 
$('#registerform').submit();

this will submit btnsubmit =Save as GET value to register.php form.

To make it work:

Add jstl and standard jar files to your library.

Hope it helps.. :)

No need to stash.

git checkout -b new_branch_name

does not touch your local changes. It just creates the branch from the current HEAD and sets the HEAD there. So I guess that's what you want.

--- Edit to explain the result of checkout master ---

Are you confused because checkout master does not discard your changes?

Since the changes are only local, git does not want you to lose them too easily. Upon changing branch, git does not overwrite your local changes. The result of your checkout master is:

M   testing

, which means that your working files are not clean. git did change the HEAD, but did not overwrite your local files. That is why your last status still show your local changes, although you are on master.

If you really want to discard the local changes, you have to force the checkout with -f.

git checkout master -f

Since your changes were never committed, you'd lose them.

Try to get back to your branch, commit your changes, then checkout the master again.

git checkout new_branch
git commit -a -m"edited"
git checkout master
git status

You should get a M message after the first checkout, but then not anymore after the checkout master, and git status should show no modified files.

--- Edit to clear up confusion about working directory (local files)---

In answer to your first comment, local changes are just... well, local. Git does not save them automatically, you must tell it to save them for later. If you make changes and do not explicitly commit or stash them, git will not version them. If you change HEAD (checkout master), the local changes are not overwritten since unsaved.

here is a solution without a loop:

public static int countOccurrences(String haystack, char needle, int i){
    return ((i=haystack.indexOf(needle, i)) == -1)?0:1+countOccurrences(haystack, needle, i+1);}


System.out.println("num of dots is "+countOccurrences("a.b.c.d",'.',0));

well, there is a loop, but it is invisible :-)

Read the Apple Human Interaction Guidelines for iPhone. I believe this is not approved behavior in an app.

You can execute it same as SQL query. first, build your command/Expression and store in a variable and execute/invoke.

$command =  ".\yourExternalScriptFile.ps1" + " -param1 '$paramValue'"

It is pretty forward, I don't think it needs explanations. So all set to execute your command now,

Invoke-Expression $command

I would recommend catching the exception here

You can also set language at runtime

sqldeveloper.exe --AddVMOption=-Duser.language=en

to avoid editing sqldeveloper.conf every time you install new version.

I try this with jquery; use this and have fun :D

    jQuery.printInExcel = function (DivID) 
{ 
var ExcelApp = new ActiveXObject("Excel.Application"); 
ExcelApp.Workbooks.Add; 
ExcelApp.visible = true; 
var str = ""; 
var tblcount = 0; 
var trcount = 0;
 $("#" + DivID + " table").each(function () 
{ $(this).find("tr").each(function () 
{ var tdcount = 0; $(this).find("td").each(function () 
{ str = str + $(this).text(); ExcelApp.Cells(trcount + 1, tdcount + 1).Value = str; 
str = ""; tdcount++ 
}); 
trcount++ 
}); tblcount++ 
}); 
};

use this in your class and call it with $.printInExcel(your var);

Added some formats in one place. Hope someone get help.

I faced the same issue in PostMan and Advance REST Client both. I checked through fiddler and found that my request payload is not converted into JSON format.

I am passing my data in Body as x-www-form-urlencoded

You can fix it by using Content-Type as application/x-www-form-urlencoded in request header.

You can use this method:

String.prototype.jsonToDate = function(){
    try{
        var date;
        eval(("date = new " + this).replace(/\//g,''));
        return date;
    } 
    catch(e){
        return new Date(0);
    }
};

The best way for me was to put it in a hidden div in php blade

<div hidden id="token">{{$token}}</div>

then call it in javascript as a constant to avoid undefined var errors

const token = document.querySelector('div[id=token]').textContent

// console.log(token)

Got this error after installing mysql via home brew.

So first remove the installation. Then Reinstall via Homebrew

brew update
brew doctor
brew install mysql

Then restart mysql service

 mysql.server restart

Then run this command to set your new root password.

 mysql_secure_installation

Finally it will ask to reload the privileges. Say yes. Then login to mysql again. And use the new password you have set.

mysql -u root -p

For those looking for an answer and the others haven't worked, this might:

If you're using a component within a component (e.g. something like this in the Vue DOM):

App
  MyComponent
   ADifferentComponent
     MyComponent

Here the issue is that MyComponent is both the parent and child of itself. This throws Vue into a loop, with each component depending on the other.

There's a few solutions to this:

 1. Globally register MyComponent

vue.component("MyComponent", MyComponent)

2. Using beforeCreate

beforeCreate: function () {
  this.$options.components.MyComponent = require('./MyComponent.vue').default
}

3. Move the import into a lambda function within the components object

components: {
  MyComponent: () => import('./MyComponent.vue')
}

My preference is the third option, it's the simplest tweak and fixes the issue in my case.

More info: Vue.js Official Docs — Handling Edge Cases: Circular References Between Components

Note: if you choose method's 2 or 3, in my instance I had to use this method in both the parent and child components to stop this issue arising.

This will delete the dataframe and will release the RAM/memory

del [[df_1,df_2]]
gc.collect()
df_1=pd.DataFrame()
df_2=pd.DataFrame()

the data-frame will be explicitly set to null

in the above statements

Firstly, the self reference of the dataframe is deleted meaning the dataframe is no longer available to python there after all the references of the dataframe is collected by garbage collector (gc.collect()) and then explicitly set all the references to empty dataframe.

more on the working of garbage collector is well explained in https://stackify.com/python-garbage-collection/

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

if the meta tag is:

<meta name="url" content="www.google.com" />

JQuery will be:

const url = $('meta[name="url"]').attr('content'); // url = 'www.google.com'

JavaScript will be: (It will return whole HTML)

const metaHtml = document.getElementsByTagName('meta').url // metaHtml = '<meta name="url" content="www.google.com" />'

This generally means that the remote side closed the connection (usually by sending a TCP/IP RST packet). If you're working with a third-party application, the likely causes are:

• You are sending malformed data to the application (which could include sending an HTTPS request to an HTTP server)
• The network link between the client and server is going down for some reason
• You have triggered a bug in the third-party application that caused it to crash
• The third-party application has exhausted system resources

It's likely that the first case is what's happening.

You can fire up Wireshark to see exactly what is happening on the wire to narrow down the problem.

Without more specific information, it's unlikely that anyone here can really help you much.

Here is a simple way to filter any request/response params from the logs using HttpLoggingInterceptor :

// Request patterns to filter
private static final String[] REQUEST_PATTERNS = {
    "Content-Type",
};
// Response patterns to filter
private static final String[] RESPONSE_PATTERNS = {"Server", "server", "X-Powered-By", "Set-Cookie", "Expires", "Cache-Control", "Pragma", "Content-Length", "access-control-allow-origin"};

// Log requests and response
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
    @Override
    public void log(String message) {

        // Blacklist the elements not required
        for (String pattern: REQUEST_PATTERNS) {
            if (message.startsWith(pattern)) {
                return;
            }
        }
        // Any response patterns as well...
        for (String pattern: RESPONSE_PATTERNS) {
            if (message.startsWith(pattern)) {
                return;
            }
        }
        Log.d("RETROFIT", message);
    }
});
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

The problem might be in the rest of the html, the part that you didn't post.

With this example (I just closed the open tags):

<a class="item" ng-href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026" href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026">
<div class="col-lg-2 col-sm-3 col-xs-4 item-list-image">
<img ng-src="csa/images/library/Service_Design.png" src="csa/images/library/Service_Design.png">
</div>
<div class="col-lg-8 col-sm-9 col-xs-8">
<div class="col-xs-12">
    <p>
    <strong class="ng-binding">Smoke Sequential</strong>
    </p>
    </div>
</div>
</a>

I was able to find the element without trouble with:

driver.findElement(By.linkText("Smoke Sequential")).click();

If there is more text inside the element, you could try a find by partial link text:

driver.findElement(By.partialLinkText("Sequential")).click();

if you are using gridview then you can show only the time with DataFormatString="{0:t}" example:

    By bind the value:-
<asp:Label ID="lblreg" runat="server" Text='<%#Eval("Registration_Time ", "{0:t}") %>'></asp:Label>

By bound filed:-
<asp:BoundField DataField=" Registration_Time" HeaderText="Brithday" SortExpression=" Registration Time " DataFormatString="{0:t}"/>

psxls gave a great answer but I think my Notepad++ version is slightly different so the $ (dollar sign) capturing did not work.

I have Notepad++ v.5.9.3 and here's how you can accomplish your task:

Search for the pattern: value=\"([0-9]*)\" And replace with: \1 (whatever you want to do around that capturing group)

Ex. Surround with square brackets

[\1] --> will produce value="[4]"

In a function, use as

render: function (args) {
    if (args.value != 0)
        return (parseFloat(args.value).toFixed(2));


},

For those running Postgres.app:

1. Add the following code to your .bash_profile:

   export PATH=/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH
   

2. Restart terminal.

The answers and the documentation provided by MSDN is the best, but I would like to add one typical case that I use a lot which requires the use of #pragma comment to send a command to the linker at link time for example

#pragma comment(linker,"/ENTRY:Entry")

tell the linker to change the entry point form WinMain() to Entry() after that the CRTStartup going to transfer controll to Entry()

Swift 4 and above

@IBAction func submitAction(sender: UIButton) {

    //declare parameter as a dictionary which contains string as key and value combination. considering inputs are valid

    let parameters = ["id": 13, "name": "jack"]

    //create the url with URL
    let url = URL(string: "www.thisismylink.com/postName.php")! //change the url

    //create the session object
    let session = URLSession.shared

    //now create the URLRequest object using the url object
    var request = URLRequest(url: url)
    request.httpMethod = "POST" //set http method as POST

    do {
        request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body
    } catch let error {
        print(error.localizedDescription)
    }

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    //create dataTask using the session object to send data to the server
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in

        guard error == nil else {
            return
        }

        guard let data = data else {
            return
        }

        do {
            //create json object from data
            if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
                print(json)
                // handle json...
            }
        } catch let error {
            print(error.localizedDescription)
        }
    })
    task.resume()
}

Using the constructor

Translates the decimal String representation of a BigInteger into a BigInteger.

Javadoc

While working with spark in EMR I was having the same problem and setting maximizeResourceAllocation=true did the trick; hope it helps someone. You have to set it when you create the cluster. From the EMR docs:

aws emr create-cluster --release-label emr-5.4.0 --applications Name=Spark \
--instance-type m3.xlarge --instance-count 2 --service-role EMR_DefaultRole --ec2-attributes InstanceProfile=EMR_EC2_DefaultRole --configurations https://s3.amazonaws.com/mybucket/myfolder/myConfig.json

Where myConfig.json should say:

[
  {
    "Classification": "spark",
    "Properties": {
      "maximizeResourceAllocation": "true"
    }
  }
]

users.toList().RemoveAll(user => <your condition>)

This depends. If you are concerned that your variable could end up as something that resolves to TRUE. Then hard checking is a must. Otherwise it is up to you. However, I doubt that the syntax whatever == TRUE would ever confuse anyone who knew what they were doing.

From Python 2.5 onwards you can do:

value = b if a > 10 else c

Previously you would have to do something like the following, although the semantics isn't identical as the short circuiting effect is lost:

value = [c, b][a > 10]

There's also another hack using 'and ... or' but it's best to not use it as it has an undesirable behaviour in some situations that can lead to a hard to find bug. I won't even write the hack here as I think it's best not to use it, but you can read about it on Wikipedia if you want.

How the synchronized Java keyword works

When you add the synchronized keyword to a static method, the method can only be called by a single thread at a time.

In your case, every method call will:

• create a new SessionFactory
• create a new Session
• fetch the entity
• return the entity back to the caller

However, these were your requirements:

• I want this to prevent access to info to the same DB instance.
• preventing getObjectById being called for all classes when it is called by a particular class

So, even if the getObjectById method is thread-safe, the implementation is wrong.

SessionFactory best practices

The SessionFactory is thread-safe, and it's a very expensive object to create as it needs to parse the entity classes and build the internal entity metamodel representation.

So, you shouldn't create the SessionFactory on every getObjectById method call.

Instead, you should create a singleton instance for it.

private static final SessionFactory sessionFactory = new Configuration()
    .configure()
    .buildSessionFactory();

The Session should always be closed

You didn't close the Session in a finally block, and this can leak database resources if an exception is thrown when loading the entity.

According to the Session.load method JavaDoc might throw a HibernateException if the entity cannot be found in the database.

You should not use this method to determine if an instance exists (use get() instead). Use this only to retrieve an instance that you assume exists, where non-existence would be an actual error.

That's why you need to use a finally block to close the Session, like this:

public static synchronized Object getObjectById (Class objclass, Long id) {    
     Session session = null;
     try {
         session = sessionFactory.openSession();
         return session.load(objclass, id);
     } finally {
         if(session != null) {
             session.close(); 
         }
     }
 }

Preventing multi-thread access

In your case, you wanted to make sure only one thread gets access to that particular entity.

But the synchronized keyword only prevents two threads from calling the getObjectById concurrently. If the two threads call this method one after the other, you will still have two threads using this entity.

So, if you want to lock a given database object so no other thread can modify it, then you need to use database locks.

The synchronized keyword only works in a single JVM. If you have multiple web nodes, this will not prevent multi-thread access across multiple JVMs.

What you need to do is use LockModeType.PESSIMISTIC_READ or LockModeType.PESSIMISTIC_WRITE while applying the changes to the DB, like this:

Session session = null;
EntityTransaction tx = null;

try {
    session = sessionFactory.openSession();
    
    tx = session.getTransaction();
    tx.begin();

    Post post = session.find(
        Post.class, 
        id, 
        LockModeType.LockModeType.PESSIMISTIC_READ
    );

    post.setTitle("High-Performance Java Perisstence");

    tx.commit();
} catch(Exception e) {
    LOGGER.error("Post entity could not be changed", e);
    if(tx != null) {
        tx.rollback(); 
    }
} finally {
    if(session != null) {
        session.close(); 
    }
}

So, this is what I did:

• I created a new EntityTransaction and started a new database transaction
• I loaded the Post entity while holding a lock on the associated database record
• I changed the Post entity and committed the transaction
• In the case of an Exception being thrown, I rolled back the transaction

Try this:

num = input("Please input your number: ")

num = float("%0.2f" % (num))

print(num)

I believe this is a lot simpler. For 1 decimal place use %0.1f. For 2 decimal places use %0.2f and so on.

Or, if you want to reduce it all to 2 lines:

num = float("%0.2f" % (float(input("Please input your number: "))))
print(num)

I needed a solution for this issue as well and I used the answers in this thread to come up with the following:

.directive('tpReport', ['$parse', '$http', '$compile', '$templateCache', function($parse, $http, $compile, $templateCache)
    {
        var getTemplateUrl = function(type)
        {
            var templateUrl = '';

            switch (type)
            {
                case 1: // Table
                    templateUrl = 'modules/tpReport/directives/table-report.tpl.html';
                    break;
                case 0:
                    templateUrl = 'modules/tpReport/directives/default.tpl.html';
                    break;
                default:
                    templateUrl = '';
                    console.log("Type not defined for tpReport");
                    break;
            }

            return templateUrl;
        };

        var linker = function (scope, element, attrs)
        {

            scope.$watch('data', function(){
                var templateUrl = getTemplateUrl(scope.data[0].typeID);
                var data = $templateCache.get(templateUrl);
                element.html(data);
                $compile(element.contents())(scope);

            });



        };

        return {
            controller: 'tpReportCtrl',
            template: '<div>{{data}}</div>',
            // Remove all existing content of the directive.
            transclude: true,
            restrict: "E",

Include in your html:

<tp-report data='data'></tp-report>

This directive is used for dynamically loading report templates based on the dataset retrieved from the server.

It sets a watch on the scope.data property and whenever this gets updated (when the users requests a new dataset from the server) it loads the corresponding directive to show the data.

I have fixed the same issue with below steps

1. Open project directory Using Terminal (which you are using i.e. mintty )
2. Now install composer within this directory as per given directions on https://getcomposer.org/download/

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

php -r "if (hash_file('SHA384', 'composer-setup.php') === 'the-provided-hash-code') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php php -r "unlink('composer-setup.php');"

3. Now run your command.

Everything is working fine now because the composer.phar file is available within the current project directory.

1. Open notepad as administrator(right click on it then click run as administrator)
2. Open the following document from Netbeans directory via Notepad file->open. Make sure where it was installed.

C:\Program Files\NetBeans 8.2\etc\netbeans.conf

3. Add the following path;

netbeans_jdkhome="C:\Program Files\Java\jdk1.8.0_171"

4. Save it as netbeans.conf in the same place.
5. Now open the Netbeans.. Everything will work properly but you will be notified regarding jdk path in the beginning..

Ok, here's a basic join query that gets the correct records:

   int[] selectedRolesArr = GetSelectedRoles();
    if( selectedRolesArr != null && selectedRolesArr.Length > 0 ) 
    {

    //this join version requires the use of distinct to prevent muliple records
        //being returned for users with more than one company role.
    IQueryable retVal = (from u in context.Users
                        join c in context.CompanyRolesToUsers
                          on u.Id equals c.UserId
                        where u.LastName.Contains( "fra" ) &&
                            selectedRolesArr.Contains( c.CompanyRoleId )
                        select  u).Distinct();
}

But here's the code that most easily integrates with the algorithm that we already had in place:

int[] selectedRolesArr = GetSelectedRoles(); 
if ( useAnd ) 
       { 
          predicateAnd = predicateAnd.And( u => (from c in context.CompanyRolesToUsers 
                       where selectedRolesArr.Contains(c.CompanyRoleId) 
                       select c.UserId).Contains(u.Id)); 
        } 
        else 
        { 
           predicateOr = predicateOr.Or( u => (from c in context.CompanyRolesToUsers 
                          where selectedRolesArr.Contains(c.CompanyRoleId) 
                         select c.UserId).Contains(u.Id) ); 
        } 

which is thanks to a poster at the LINQtoSQL forum

Setting width to 'resolve' didn't work for me. Instead, i added "width:100%" to my select, and modified the css like this :

.select2-offscreen {position: fixed !important;}

This was the only solution that worked for me (my version is 2.2.1) Your select will take all the available place, it is better than using

class="input-medium"

from bootstrap, because the select is always staying in the container, even after resizing the window (responsive)

It turns out this is actually possible, but not using the genuine Docker CE or EE version.

You can either use Red Hat's fork of docker with the '--add-registry' flag or you can build docker from source yourself with registry/config.go modified to use your own hard-coded default registry namespace/index.

Polynomial time.

A polynomial is a sum of terms that look like Constant * x^k Exponential means something like Constant * k^x

(in both cases, k is a constant and x is a variable).

The execution time of exponential algorithms grows much faster than that of polynomial ones.

I know this is an older post, but I just got hit with a similar issue and was able to resolve it, so I thought I'd share.

(Update: As noted in the comments below, this answer was before the inclusion of the "git stash" feature to eGit.)

What I did was:

1. Copy out the local copy of the conflicting file that may or may not have any changes from the version on the upstream.
2. Within Eclipse, "Revert" the file to the version right before the conflict.
3. Run a "Pull" from the remote repository, allowing all changes to be synced to the local work directory. This should clear the updates coming down to your filesystem, leaving only what you have left to push.
4. Check the current version of the conflicting file in your work directory with the copy you copied out. If there are any differences, do a proper merge of the files and commit that version of the file in the work directory.
5. Now "Push" your changes up.

Hope that helps.

So what about having:

$data['cat']='wagon';

This works great for large tables.

SELECT NUM_ROWS FROM ALL_TABLES WHERE TABLE_NAME = 'TABLE_NAME_IN_UPPERCASE';

For small to medium size tables, following will be ok.

SELECT COUNT(Primary_Key) FROM table_name;

Cheers,

Updated eclipse.ini file with key value property -Dosgi.requiredJavaVersion=1.7 (or) 1.8 whichever applicable. - it works for me.

This is my solution:

public static bool OverlappingPeriods(DateTime aStart, DateTime aEnd,
                                      DateTime bStart, DateTime bEnd)
{
    if (aStart > aEnd)
        throw new ArgumentException("A start can not be after its end.");

    if(bStart > bEnd)
        throw new ArgumentException("B start can not be after its end.");

    return !((aEnd < bStart && aStart < bStart) ||
                (bEnd < aStart && bStart < aStart));
}

I unit tested it with 100% coverage.

Something to keep in mind when creating formatters is to try to reuse the same instance if you can, as formatters are fairly computationally expensive to create. The following is a pattern I frequently use for apps where I can share the same formatter app-wide, adapted from NSHipster.

extension DateFormatter {

    static var sharedDateFormatter: DateFormatter = {
        let dateFormatter = DateFormatter()   
        // Add your formatter configuration here     
        dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
        return dateFormatter
    }()
}

Usage:

let dateString = DateFormatter.sharedDateFormatter.string(from: Date())

The answers here are not actually completely correct. Close, but there's an edge case.

The difference is that $('body') actually selects the element by the tag name, whereas document.body references the direct object on the document.

That means if you (or a rogue script) overwrites the document.body element (shame!) $('body') will still work, but $(document.body) will not. So by definition they're not equivalent.

I'd venture to guess there are other edge cases (such as globally id'ed elements in IE) that would also trigger what amounts to an overwritten body element on the document object, and the same situation would apply.

With Underscore.js, to merge an array of objects do:

var arrayOfObjects = [ {a:1}, {b:2, c:3}, {d:4} ];
_(arrayOfObjects).reduce(function(memo, o) { return _(memo).extend(o); });

It results in:

Object {a: 1, b: 2, c: 3, d: 4}

Strings in Java are immutable. That means whenever you try to change/modify the string you get a new instance. You cannot change the original string. This has been done so that these string instances can be cached. A typical program contains a lot of string references and caching these instances can decrease the memory footprint and increase the performance of the program.

When using == operator for string comparison you are not comparing the contents of the string, but are actually comparing the memory address. If they are both equal it will return true and false otherwise. Whereas equals in string compares the string contents.

So the question is if all the strings are cached in the system, how come == returns false whereas equals return true? Well, this is possible. If you make a new string like String str = new String("Testing") you end up creating a new string in the cache even if the cache already contains a string having the same content. In short "MyString" == new String("MyString") will always return false.

Java also talks about the function intern() that can be used on a string to make it part of the cache so "MyString" == new String("MyString").intern() will return true.

Note: == operator is much faster than equals just because you are comparing two memory addresses, but you need to be sure that the code isn't creating new String instances in the code. Otherwise you will encounter bugs.

You could try:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.ToArray());

Not sure if .ToArray() is available for the collection. If you do use the code you posted, make sure you initialize the List with the number of existing elements:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.Count);  // or .Length

You could also do something like this:

df = df[['x', 'y', 'a', 'b']]

You can get the list of columns with:

cols = list(df.columns.values)

The output will produce something like this:

['a', 'b', 'x', 'y']

...which is then easy to rearrange manually before dropping it into the first function

If you are using Angular 2 (apparently it also works for Angular 4 too), you can use the following to round to two decimal places{{ exampleNumber | number : '1.2-2' }}, as in:

<ion-input value="{{ exampleNumber | number : '1.2-2' }}"></ion-input>

BREAKDOWN

'1.2-2' means {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}:

• A minimum of 1 digit will be shown before decimal point
• It will show at least 2 digits after decimal point
• But not more than 2 digits

It is implementation dependent.

For example, under Windows they are the same, but for example on Alpha systems a long was 64 bits whereas an int was 32 bits. This article covers the rules for the Intel C++ compiler on variable platforms. To summarize:

  OS           arch           size
Windows       IA-32        4 bytes
Windows       Intel 64     4 bytes
Windows       IA-64        4 bytes
Linux         IA-32        4 bytes
Linux         Intel 64     8 bytes
Linux         IA-64        8 bytes
Mac OS X      IA-32        4 bytes
Mac OS X      Intel 64     8 bytes  

It's basically 2 step process:

First, you need to stringify like this:

var JSON_VAR = JSON.stringify(OBJECT_NAME, null, 2); 

After that, you need to convert the string to Object:

var obj = JSON.parse(JSON_VAR);

SQLite is created in your python directory where you installed the python.

Deleting Elements in an Array if Element is a Certain value VBA

to delete elements in an Array wih certain condition, you can code like this

For i = LBound(ArrValue, 2) To UBound(ArrValue, 2)
    If [Certain condition] Then
        ArrValue(1, i) = "-----------------------"
    End If
Next i

StrTransfer = Replace(Replace(Replace(join(Application.Index(ArrValue(), 1, 0), ","), ",-----------------------,", ",", , , vbBinaryCompare), "-----------------------,", "", , , vbBinaryCompare), ",-----------------------", "", , , vbBinaryCompare)
ResultArray = join( Strtransfer, ",")

I often manipulate 1D-Array with Join/Split but if you have to delete certain value in Multi Dimension I suggest you to change those Array into 1D-Array like this

strTransfer = Replace(Replace(Replace(Replace(Names.Add("A", MultiDimensionArray), Chr(34), ""), "={", ""), "}", ""), ";", ",")
'somecode to edit Array like 1st code on top of this comment
'then loop through this strTransfer to get right value in right dimension
'with split function.

Apart from having a Path variable, the directory C:\data\db is mandatory.

Create this and the error shall be solved.

Given you have installed node on your system, install Express locally for your project using the following for Windows:

npm install express

or

npm install express --save

You might give it global access by using:

npm install -g express --save

An add-on to the previous answers since I came across this concern:

If you really want to insert something like 24-May-2005 to your DATE column, you could do something like this:

INSERT INTO someTable(Empid,Date_Joined)
VALUES
    ('S710',STR_TO_DATE('24-May-2005', '%d-%M-%Y'));

In the above query please note that if it's May(ie: the month in letters) the format should be %M.

NOTE: I tried this with the latest MySQL version 8.0 and it works!

I believe pwdencrypt is using a hash so you cannot really reverse the hashed string - the algorithm is designed so it's impossible.

If you are verifying the password that a user entered the usual technique is to hash it and then compare it to the hashed version in the database.

This is how you could verify a usered entered table

SELECT password_field FROM mytable WHERE password_field=pwdencrypt(userEnteredValue)

Replace userEnteredValue with (big surprise) the value that the user entered :)

        def jsonFile = new File('File Path');

        String json = JsonOutput.toJson(parseJson)
        def prettyJson = JsonOutput.prettyPrint(json)
        println(prettyJson)

If on your system User Control Account is Off then you can run the XAMPP as Administrator and check the boxes for run as service.

And if on your system User Control Account is On then it may not work. You have go to Configuration files and manually install as a service or run apache_installservice.bat for Apache and mysql_installservice.bat for MySQL at the path

1. C:\xampp\apache
2. C:\xampp\mysql

if path is the default path.

You can import the whole module as follows:

Yes, it’s frustrating—sometimes type and other programs print gibberish, and sometimes they do not.

First of all, Unicode characters will only display if the current console font contains the characters. So use a TrueType font like Lucida Console instead of the default Raster Font.

But if the console font doesn’t contain the character you’re trying to display, you’ll see question marks instead of gibberish. When you get gibberish, there’s more going on than just font settings.

When programs use standard C-library I/O functions like printf, the program’s output encoding must match the console’s output encoding, or you will get gibberish. chcp shows and sets the current codepage. All output using standard C-library I/O functions is treated as if it is in the codepage displayed by chcp.

Matching the program’s output encoding with the console’s output encoding can be accomplished in two different ways:

• A program can get the console’s current codepage using chcp or GetConsoleOutputCP, and configure itself to output in that encoding, or

• You or a program can set the console’s current codepage using chcp or SetConsoleOutputCP to match the default output encoding of the program.

However, programs that use Win32 APIs can write UTF-16LE strings directly to the console with WriteConsoleW. This is the only way to get correct output without setting codepages. And even when using that function, if a string is not in the UTF-16LE encoding to begin with, a Win32 program must pass the correct codepage to MultiByteToWideChar. Also, WriteConsoleW will not work if the program’s output is redirected; more fiddling is needed in that case.

type works some of the time because it checks the start of each file for a UTF-16LE Byte Order Mark (BOM), i.e. the bytes 0xFF 0xFE. If it finds such a mark, it displays the Unicode characters in the file using WriteConsoleW regardless of the current codepage. But when typeing any file without a UTF-16LE BOM, or for using non-ASCII characters with any command that doesn’t call WriteConsoleW—you will need to set the console codepage and program output encoding to match each other.

How can we find this out?

Here’s a test file containing Unicode characters:

ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

Here’s a Java program to print out the test file in a bunch of different Unicode encodings. It could be in any programming language; it only prints ASCII characters or encoded bytes to stdout.

import java.io.*;

public class Foo {

    private static final String BOM = "\ufeff";
    private static final String TEST_STRING
        = "ASCII     abcde xyz\n"
        + "German    äöü ÄÖÜ ß\n"
        + "Polish    aezznl\n"
        + "Russian   ??????? ???\n"
        + "CJK       ??\n";

    public static void main(String[] args)
        throws Exception
    {
        String[] encodings = new String[] {
            "UTF-8", "UTF-16LE", "UTF-16BE", "UTF-32LE", "UTF-32BE" };

        for (String encoding: encodings) {
            System.out.println("== " + encoding);

            for (boolean writeBom: new Boolean[] {false, true}) {
                System.out.println(writeBom ? "= bom" : "= no bom");

                String output = (writeBom ? BOM : "") + TEST_STRING;
                byte[] bytes = output.getBytes(encoding);
                System.out.write(bytes);
                FileOutputStream out = new FileOutputStream("uc-test-"
                    + encoding + (writeBom ? "-bom.txt" : "-nobom.txt"));
                out.write(bytes);
                out.close();
            }
        }
    }
}

The output in the default codepage? Total garbage!

However, what if we type the files that got saved? They contain the exact same bytes that were printed to the console.

The only thing that works is UTF-16LE file, with a BOM, printed to the console via type.

If we use anything other than type to print the file, we get garbage:

Z:\andrew\projects\sx\1259084>copy uc-test-UTF-16LE-bom.txt CON
 ¦A S C I I           a b c d e   x y z
 G e r m a n         õ ÷ ³   - Í _   ¯

 C J K               `O}Y
         1 file(s) copied.

From the fact that copy CON does not display Unicode correctly, we can conclude that the type command has logic to detect a UTF-16LE BOM at the start of the file, and use special Windows APIs to print it.

We can see this by opening cmd.exe in a debugger when it goes to type out a file:

After type opens a file, it checks for a BOM of 0xFEFF—i.e., the bytes 0xFF 0xFE in little-endian—and if there is such a BOM, type sets an internal fOutputUnicode flag. This flag is checked later to decide whether to call WriteConsoleW.

But that’s the only way to get type to output Unicode, and only for files that have BOMs and are in UTF-16LE. For all other files, and for programs that don’t have special code to handle console output, your files will be interpreted according to the current codepage, and will likely show up as gibberish.

You can emulate how type outputs Unicode to the console in your own programs like so:

#include <stdio.h>
#define UNICODE
#include <windows.h>

static LPCSTR lpcsTest =
    "ASCII     abcde xyz\n"
    "German    äöü ÄÖÜ ß\n"
    "Polish    aezznl\n"
    "Russian   ??????? ???\n"
    "CJK       ??\n";

int main() {
    int n;
    wchar_t buf[1024];

    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    n = MultiByteToWideChar(CP_UTF8, 0,
            lpcsTest, strlen(lpcsTest),
            buf, sizeof(buf));

    WriteConsole(hConsole, buf, n, &n, NULL);

    return 0;
}

This program works for printing Unicode on the Windows console using the default codepage.

For the sample Java program, we can get a little bit of correct output by setting the codepage manually, though the output gets messed up in weird ways:

Z:\andrew\projects\sx\1259084>chcp 65001
Active code page: 65001

Z:\andrew\projects\sx\1259084>java Foo
== UTF-8
= no bom
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

CJK       ??
  ??
?
?
== UTF-16LE
= no bom
A S C I I           a b c d e   x y z
…

However, a C program that sets a Unicode UTF-8 codepage:

#include <stdio.h>
#include <windows.h>

int main() {
    int c, n;
    UINT oldCodePage;
    char buf[1024];

    oldCodePage = GetConsoleOutputCP();
    if (!SetConsoleOutputCP(65001)) {
        printf("error\n");
    }

    freopen("uc-test-UTF-8-nobom.txt", "rb", stdin);
    n = fread(buf, sizeof(buf[0]), sizeof(buf), stdin);
    fwrite(buf, sizeof(buf[0]), n, stdout);

    SetConsoleOutputCP(oldCodePage);

    return 0;
}

does have correct output:

Z:\andrew\projects\sx\1259084>.\test
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

The moral of the story?

• type can print UTF-16LE files with a BOM regardless of your current codepage
• Win32 programs can be programmed to output Unicode to the console, using WriteConsoleW.
• Other programs which set the codepage and adjust their output encoding accordingly can print Unicode on the console regardless of what the codepage was when the program started
• For everything else you will have to mess around with chcp, and will probably still get weird output.

Try this.

Single:

SELECT *  FROM (VALUES ('Hello world')) t1 (col1) WHERE 1 = 1

Multi:

SELECT *  FROM (VALUES ('Hello world'),('Hello world'),('Hello world')) t1 (col1) WHERE 1 = 1

I had the same issue:

raise SSLError(e)
requests.exceptions.SSLError: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol

I had fiddler running, I stopped fiddler capture and did not see this error. Could be because of fiddler.

It is possible to do (in the deployed repository)

git fetch
git checkout origin/master -- path/to/file

The fetch will download all the recent changes, but it will not put it in your current checked out code (working area).

The checkout will update the working tree with the particular file from the downloaded changes (origin/master).

At least this works for me for those little small typo fixes, where it feels weird to create a branch etc just to change one word in a file.

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles

.modal {
    display: block;
}
.modal-body:before,
.modal-body:after {
    display: table;
    content: " ";
}
.modal-header:before,
.modal-header:after {
    display: table;
    content: " ";
}

(The last ones are necessary if you use custom directives) and encapsulate the html with

<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <h4 class="modal-title">Modal title</h4>
    </div>
    <div class="modal-body">
      ...
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      <button type="button" class="btn btn-primary">Save changes</button>
    </div>
  </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

For anyone finding this. Your better off using the jQuery UI version because it works on all browsers. The color plugin has issues with Safari and Chrome. It only works sometimes.

onClick="javascript:this.form.submit();">

this in div onclick don't have attribute form, you may try this.parentNode.submit() or document.forms[0].submit() will do

Also, onClick, should be onclick, some browsers don't work with onClick

You can't remove anything from an array - they're always fixed length. Once you've created an array of length 3, that array will always have length 3.

You'd be better off with a List<String>, e.g. an ArrayList<String>:

List<String> list = new ArrayList<String>();
list.add("google");
list.add("microsoft");
list.add("apple");
System.out.println(list.size()); // 3

list.remove("apple");
System.out.println(list.size()); // 2

Collections like this are generally much more flexible than working with arrays directly.

EDIT: For removal:

void removeRandomElement(List<?> list, Random random)
{
    int index = random.nextInt(list.size());
    list.remove(index);
}

if (f <= LONG_MIN || f >= LONG_MAX || f == (long)f) /* it's an integer */

You can use offsetWidth. Refer to this post and question for more.

console.log("width:" + document.getElementsByTagName("div")[0].offsetWidth + "px");

div {border: 1px solid #F00;}

<div style="width: 100%; height: 10px;"></div>

@section is for defining a content are override from a shared view. Basically, it is a way for you to adjust your shared view (similar to a Master Page in Web Forms).

You might find Scott Gu's write up on this very interesting.

Edit: Based on additional question clarification

The @RenderSection syntax goes into the Shared View, such as:

<div id="sidebar">
    @RenderSection("Sidebar", required: false)
</div>

This would then be placed in your view with @Section syntax:

@section Sidebar{
    <!-- Content Here -->
}

In MVC3+ you can either define the Layout file to be used for the view directly or you can have a default view for all views.

Common view settings can be set in _ViewStart.cshtml which defines the default layout view similar to this:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

You can also set the Shared View to use directly in the file, such as index.cshtml directly as shown in this snippet.

@{
    ViewBag.Title = "Corporate Homepage";
    ViewBag.BodyID = "page-home";
    Layout = "~/Views/Shared/_Layout2.cshtml";
}

There are a variety of ways you can adjust this setting with a few more mentioned in this SO answer.

I recommend you to use the open-source package guzzle that is fully unit tested and uses the latest coding practices.

Go to the command line in your project folder and type in the following command (assuming you already have the package manager composer installed). If you need help how to install Composer, you should have a look here.

php composer.phar require guzzlehttp/guzzle

Using Guzzle to send a POST request

The usage of Guzzle is very straight forward as it uses a light-weight object-oriented API:

// Initialize Guzzle client
$client = new GuzzleHttp\Client();

// Create a POST request
$response = $client->request(
    'POST',
    'http://example.org/',
    [
        'form_params' => [
            'key1' => 'value1',
            'key2' => 'value2'
        ]
    ]
);

// Parse the response object, e.g. read the headers, body, etc.
$headers = $response->getHeaders();
$body = $response->getBody();

// Output headers and body for debugging purposes
var_dump($headers, $body);

According to the official documentation, a click on any link in WebView launches an application that handles URLs, which by default is a browser. You need to override the default behavior like this

    myWebView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }
    });

if (str.toLowerCase().indexOf("yes") >= 0)

Or,

if (/yes/i.test(str))

I posted this in another question, but I find using tables with iTextSharp offers a great level of precision.

document.Add(BlankLineDoc(16));

public static PdfPTable BlankLineDoc(int height)
{
    var table = new PdfPTable(1) {WidthPercentage = 100};
    table = BlankLineTable(table, height);
    return table;
}

public static PdfPTable BlankLineTable(PdfPTable table, int height, int border = Rectangle.NO_BORDER)
{
    var cell = new PdfPCell(new Phrase(" "))
    {
        Border = border,
        Colspan = table.NumberOfColumns,
        FixedHeight = height
    };
    table.AddCell(cell);
    return table;
}

BlankLineTable can be used directly when working with tables

As much as I prefer this approach:-

    api.com/users?id=id1,id2,id3,id4,id5

The correct way is

    api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5

or

    api.com/users?ids=id1&ids=id2&ids=id3&ids=id4&ids=id5

This is how rack does it. This is how php does it. This is how node does it as well...

Note that if strings has spaces then quotation marks are needed at definition and must be chopped while concatenating:

rem The retail files set
set FILES_SET="(*.exe *.dll"

rem The debug extras files set
set DEBUG_EXTRA=" *.pdb"

rem Build the DEBUG set without any
set FILES_SET=%FILES_SET:~1,-1%%DEBUG_EXTRA:~1,-1%

rem Append the closing bracket
set FILES_SET=%FILES_SET%)

echo %FILES_SET%

Put a checkmark on Microsoft.VisualBasic.

Hit OK.

That link is for Visual Studio 2013, you can use the "Other versions" dropdown for different versions of visual studio.

In all cases you need to add a reference to the .NET assembly "Microsoft.VisualBasic".

At the top of your c# file you neeed:

using Microsoft.VisualBasic;

Then you can look at writing the code.

The code would be something like:

   private void btnOK_Click(object sender, EventArgs e)
   {
      if ( Information.IsNumeric(startingbudget) )
      {
         MessageBox.Show("This is a number.");
      }
   }

This can be done by using SUMPRODUCT as well. Update the ranges as you see fit

=SUMPRODUCT(($A$2:$A$7=A2)*($B$2:$B$7=B2)*$C$2:$C$7)

A2:A7 = First name range

B2:B7 = Last Name Range

C2:C7 = Numbers Range

This will find all the names with the same first and last name and sum the numbers in your numbers column

Now I solved this issue in this way,

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.io.OutputStream;
// Create a trust manager that does not validate certificate chains like the 
default TrustManager[] trustAllCerts = new TrustManager[] {
    new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }
        public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
            //No need to implement. 
        }
        public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
            //No need to implement. 
        }
    }
};
// Install the all-trusting trust manager
try {
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
    System.out.println(e);
}

You can use a list comprehension:

>>> s = 'hi'
>>> [ord(c) for c in s]
[104, 105]

For reading "plain" CSV files in Java, there is a library called OpenCSV, available here: http://opencsv.sourceforge.net/

Import JSON/CSV file in MongoDB

• wait wait
• first check mongoimport.exe file in your bin folder(C:\Program Files\MongoDB\Server\4.4\bin) if it is not then download mongodb database tools(https://www.mongodb.com/try/download/database-tools)
• copy extracted(unzip) files(inside unzipped bin) to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
• copy your json file to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
• Now open your commond prompt change its directory to bin

cd "C:\Program Files\MongoDB\Server\4.4\bin"

• Now copy this on your commnad prompt

mongoimport -d tymongo -c test --type json --file restaurants.json

• where d- database(tymongo-database name), c-collection(test-collection name)

FOR CSV FILE

 mongoimport -d tymongo -c test --type csv --file database2.csv --headerline

I imagine that trygetvalue is doing something more like:

if(myDict.ReallyOptimisedVersionofContains(someKey))
{ 
  someVal = myDict[someKey];
  return true;
}
return false;

So hopefully no try/catch anywhere.

I think it is just a method of convenience really. I generally use it as it saves a line of code or two.

Vaulstein answer helped me.

I did not find the pip.ini file anywhere on my pc. So did the following.

1. Went to the the AppData folder. You can get the appdata folder by opening up the command prompt and type echo %AppData%

Or simply type %AppData% in windows explorer.

2. Create a folder called pip inside of that appdata folder.

3. In that pip folder that you just created, create a simple textfile called pip.ini

4. Past the following config settings in that file using a simple editor of your choice.

pip.ini file:

[list]
format=columns

[global]
trusted-host = pypi.python.org pypi.org

You should now be good to go.

You have at least two options:

• str.zfill: lambda n, cnt=2: str(n).zfill(cnt)
• % formatting: lambda n, cnt=2: "%0*d" % (cnt, n)

If on Python >2.5, see a third option in clorz's answer.

The .pde file extension is the one used by the Processing, Wiring, and the Arduino IDE.

Processing is not C-based but rather Java-based and with a syntax derived from Java. It is a Java framework that can be used as a Java library. It includes a default IDE that uses .pde extension. Just wanted to rectify @kersny's answer.

Wiring is a microcontroller that uses the same IDE. Arduino uses a modified version, but also with .pde. The OpenProcessing page where you found it is a website to exhibit some Processing work.

If you know Java, it should be fairly easy to convert the Processing code to Java AWT.

In C#, float is an alias for System.Single (a bit like intis an alias for System.Int32).

In my opinion, a dynamic PL/SQL block is somewhat obscure. While is very flexible, is also hard to tune, hard to debug and hard to figure out what's up. My vote goes to your first option,

EXECUTE IMMEDIATE v_query_str INTO v_num_of_employees USING p_job;

Both uses bind variables, but first, for me, is more redeable and tuneable than @jonearles option.

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

Simply use break. That will do it.

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

As of JavaScript 1.8.5 you can use Object.keys(obj) to get an Array of properties defined on the object itself (the ones that return true for obj.hasOwnProperty(key)).

Object.keys(obj).forEach(function(key,index) {
    // key: the name of the object key
    // index: the ordinal position of the key within the object 
});

This is better (and more readable) than using a for-in loop.

Its supported on these browsers:

• Firefox (Gecko): 4 (2.0)
• Chrome: 5
• Internet Explorer: 9

See the Mozilla Developer Network Object.keys()'s reference for futher information.

I had the same problem. Make sure your script didnt have

#!/bin/sh 

at the top of your script. Instead, you should add

#!/bin/bash

Message box is only defaultly available for windows form application.If you want to use the message box resource the you would have to use 'using system.windows.forms' to enable the message box for web forms mode.

With map (not as good, but another approach to the problem):

list(map(lambda x: x*5,[5, 10, 15, 20, 25]))

also, if you happen to be using numpy or numpy arrays, you could use this:

import numpy as np
list(np.array(x) * 5)

@glglgl already explained why what you were trying to do was not working. Actually, if you are really aiming at defining a variable in a header, you can trick using some preprocessor directives:

file1.c:

#include <stdio.h>

#define DEFINE_I
#include "global.h"

int main()
{
    printf("%d\n",i);
    foo();
    return 0;
}

file2.c:

#include <stdio.h>
#include "global.h"

void foo()
{
    i = 54;
    printf("%d\n",i);
}

global.h:

#ifdef DEFINE_I
int i = 42;
#else
extern int i;
#endif

void foo();

In this situation, i is only defined in the compilation unit where you defined DEFINE_I and is declared everywhere else. The linker does not complain.

I have seen this a couple of times before where an enum was declared in a header, and just below was a definition of a char** containing the corresponding labels. I do understand why the author preferred to have that definition in the header instead of putting it into a specific source file, but I am not sure whether the implementation is so elegant.

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

Source: is there a way to serialize pojo's directly to treemodel?

You can do that with list comprehension too:

A=[[x*100, x][x % 2 != 0] for x in range(1,11)]
print A

Ruby is slower than C++ at a number of easily measurable tasks (e.g., doing code that is heavily dependent on floating point). This is not very surprising, but enough justification for some people to say that “Ruby is Slow” without qualification. They don't count the fact that it is far easier and safer to write Ruby code than C++.

The best fix is to use targeted modules written in another language (e.g., C, C++, Fortran) in your Ruby code. Those can do the heavy lifting and your scripts can focus on higher level coordination issues.

You want the non-locale-aware floatval function:

float floatval ( mixed $var ) - Gets the float value of a string.

Example:

$string = '122.34343The';
$float  = floatval($string);
echo $float; // 122.34343
