No, you can't make the img stretch to fit the div and simultaneously achieve the inverse. You would have an infinite resizing loop. However, you could take some notes from other answers and implement some min and max dimensions but that wasn't the question.
You need to decide if your image will scale to fit its parent or if you want the div to expand to fit its child img.
Using this block tells me you want the image size to be variable so the parent div is the width an image scales to. height: auto
is going to keep your image aspect ratio in tact. if you want to stretch the height it needs to be 100%
like this fiddle.
img {
width: 100%;
height: auto;
}
Use the preprocessor #
operator:
#define CALL_DO_SOMETHING(VAR) do_something(#VAR, VAR);
The command to use is gdb attach pid
where pid is the process id of the process you want to attach to.
Warning. I used setAllowsRubberBanding: in my app, and Apple rejected it, stating that non-public API functions are not allowed (cite: 3.3.1)
You need to use backtick instead of single quotes:
Single quote - 'Business Name'
- Wrong
Backtick - `Business Name`
- Correct
If you have to do group by
using hibernate criteria use projections.groupPropery
like the following,
@Autowired
private SessionFactory sessionFactory;
Criteria crit = sessionFactory.getCurrentSession().createCriteria(studentModel.class);
crit.setProjection(Projections.projectionList()
.add(Projections.groupProperty("studentName").as("name"))
List result = crit.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP).list();
return result;
All of the answers here are great; but only one of them (the most voted one) relates to how your code works. Others are relating to generators in general, and how they work.
So I won't repeat what generators are or what yields do; I think these are covered by great existing answers. However, after spending few hours trying to understand a similar code to yours, I'll break it down how it works.
Your code traverse a binary tree structure. Let's take this tree for example:
5
/ \
3 6
/ \ \
1 4 8
And another simpler implementation of a binary-search tree traversal:
class Node(object):
..
def __iter__(self):
if self.has_left_child():
for child in self.left:
yield child
yield self.val
if self.has_right_child():
for child in self.right:
yield child
The execution code is on the Tree
object, which implements __iter__
as this:
def __iter__(self):
class EmptyIter():
def next(self):
raise StopIteration
if self.root:
return self.root.__iter__()
return EmptyIter()
The while candidates
statement can be replaced with for element in tree
; Python translate this to
it = iter(TreeObj) # returns iter(self.root) which calls self.root.__iter__()
for element in it:
.. process element ..
Because Node.__iter__
function is a generator, the code inside it is executed per iteration. So the execution would look like this:
for
iterate them (let's call it it1 because its the first iterator object)for
is executed. The for child in self.left
creates a new iterator from self.left
, which is a Node object itself (it2)iterator
is created (it3)it3
has no left childs so it continues and yield self.value
next(it3)
it raises StopIteration
and exists since it has no right childs (it reaches to the end of the function without yield anything)it1
and it2
are still active - they are not exhausted and calling next(it2)
would yield values, not raise StopIteration
it2
context, and call next(it2)
which continues where it stopped: right after the yield child
statement. Since it has no more left childs it continues and yields it's self.val
.The catch here is that every iteration creates sub-iterators to traverse the tree, and holds the state of the current iterator. Once it reaches the end it traverse back the stack, and values are returned in the correct order (smallest yields value first).
Your code example did something similar in a different technique: it populated a one-element list for every child, then on the next iteration it pops it and run the function code on the current object (hence the self
).
I hope this contributed a little to this legendary topic. I spent several good hours drawing this process to understand it.
With a few CSS overrides, I find the accordion / collapse plugin works well as a sidebar vertical menu. Here's a small sample of some overrides I use for a menu on a white background. The accordion is placed within a section container:
.accordion-group
{
margin-bottom: 1px;
-webkit-border-radius: 0px;
-moz-border-radius: 0px;
border-radius: 0px;
border-bottom: 1px solid #E5E5E5;
border-top: none;
border-left: none;
border-right: none;
}
.accordion-heading:hover
{
background-color: #FFFAD9;
}
try "configuration properties -> debugging -> environment" and set the PATH variable in run-time
Another alternative to do the same thing is to filter on type=checkbox attribute:
$('input[type="checkbox"]').removeAttr('checked');
or
$('input[type="checkbox"]').prop('checked' , false);
Remeber that The difference between attributes and properties can be important in specific situations. Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

The public static void keywords mean the Java virtual machine (JVM) interpreter can call the program's main method to start the program (public) without creating an instance of the class (static), and the program does not return data to the Java VM interpreter (void) when it ends.
From the man git-stash
page:
The modifications stashed away by this command can be listed with git stash list, inspected with git stash show
show [<stash>]
Show the changes recorded in the stash as a diff between the stashed state and
its original parent. When no <stash> is given, shows the latest one. By default,
the command shows the diffstat, but it will accept any format known to git diff
(e.g., git stash show -p stash@{1} to view the second most recent stash in patch
form).
To list the stashed modifications
git stash list
To show files changed in the last stash
git stash show
So, to view the content of the most recent stash, run
git stash show -p
To view the content of an arbitrary stash, run something like
git stash show -p stash@{1}

An extremely simple way to auto-compile upon save is to type the following into the terminal:
tsc main --watch
where main.ts
is your file name.
Note, this will only run as long as this terminal is open, but it's a very simple solution that can be run while you're editing a program.
class Program
{
static void Main(string[] args)
{
Type type = typeof(MyReflectionClass);
MethodInfo method = type.GetMethod("MyMethod");
MyReflectionClass c = new MyReflectionClass();
string result = (string)method.Invoke(c, null);
Console.WriteLine(result);
}
}
public class MyReflectionClass
{
public string MyMethod()
{
return DateTime.Now.ToString();
}
}
They are hint to the compiler to emit instructions that will cause branch prediction to favour the "likely" side of a jump instruction. This can be a big win, if the prediction is correct it means that the jump instruction is basically free and will take zero cycles. On the other hand if the prediction is wrong, then it means the processor pipeline needs to be flushed and it can cost several cycles. So long as the prediction is correct most of the time, this will tend to be good for performance.
Like all such performance optimisations you should only do it after extensive profiling to ensure the code really is in a bottleneck, and probably given the micro nature, that it is being run in a tight loop. Generally the Linux developers are pretty experienced so I would imagine they would have done that. They don't really care too much about portability as they only target gcc, and they have a very close idea of the assembly they want it to generate.
It's always worth grouping elements into sections that are relevant. In your case, a parent element that contains two columns;
HTML:
<div class='container2'>
<img src='http://ecx.images-amazon.com/images/I/21-leKb-zsL._SL500_AA300_.png' class='iconDetails' />
<div class="text">
<h4>Facebook</h4>
<p>
fine location, GPS, coarse location
<span>0 mins ago</span>
</p>
</div>
</div>
CSS:
* {
padding:0;
margin:0;
}
.iconDetails {
margin:0 2%;
float:left;
height:40px;
width:40px;
}
.container2 {
width:100%;
height:auto;
padding:1%;
}
.text {
float:left;
}
.text h4, .text p {
width:100%;
float:left;
font-size:0.6em;
}
.text p span {
color:#666;
}
Use DateTime::createFromFormat like this :
$date = DateTime::createFromFormat('m/d/Y H:i:s', $input_string.' 00:00:00');
$mysql_date_string = $date->format('Y-m-d H:i:s');
You can adapt this to any input format, whereas strtotime() will assume you're using the US date format if you use /, even if you're not.
The added 00:00:00 is because createFromFormat will use the current date to fill missing data, ie : it will take the current hour:min:sec and not 00:00:00 if you don't precise it.

After a long search, I discovered that a dependency was somehow corrupted on my machine in a maven project. The strange thing was that the dependency was still working correctly in the compiled java code. When I cleaned and rebuilt my maven dependency cache however, the problem went away and IntelliJ recognized the package. You can do this by running:
mvn dependency:purge-local-repository
Intrestingly, the source of my problem hence wasn't IntelliJ, but maven itself.
Since the OP asked about CPU usage AND memory usage (accepted answer only shows technique to get cpu usage), I'd like to recommend the ActivityManager class and specifically the accepted answer from this question: How to get current memory usage in android?
I encountered the same problem, probably when I uninstalled it and tried to install it again.
This happens because of the database file containing login details is still stored in the pc, and the new password will not match the older one.
So you can solve this by just uninstalling mysql, and then removing the left over folder from the C:
drive (or wherever you must have installed).
As for security issues, here is what a security consultant will tell you on the whole field issue (this is from an actual independent security audit):
HTML Autocomplete Enabled – Password fields in HTML forms have autocomplete enabled. Most browsers have a facility to remember user credentials entered into HTML forms.
Relative Risk: Low
Affected Systems/Devices: o https://*******/
I also agree this should cover any field that contains truly private data. I feel that it is alright to force a person to always type their credit card information, CVC code, passwords, usernames, etc whenever that site is going to access anything that should be kept secure [universally or by legal compliance requirements]. For example: purchase forms, bank/credit sites, tax sites, medical data, federal, nuclear, etc - not Sites like Stack Overflow or Facebook.
Other types of sites - e.g. TimeStar Online for clocking in and out of work - it's stupid, since I always use the same PC/account at work, that I can't save the credentials on that site - strangely enough I can on my Android but not on an iPad. Even shared PCs this wouldn't be too bad since clocking in/out for someone else really doesn't do anything but annoy your supervisor. (They have to go in and delete the erroneous punches - just choose not to save on public PCs).
I too faced this error while importing an 8GB sql database file. Checked my mysql installation drive. There was no space left in the drive. So got some space by removing unwanted items and re-ran my database import command. This time it was successful.
The given answer is far from complete. In fact, it is so far from complete that it tends to lead the reader to believe that this answer is OS dependent when it isn't. It also isn't something which is programming language dependent (as some commentators have suggested). I'm going to add more information in order to make this more clear. First, lets give the list of current new line variations (as in, what they've been since 1999):
\r\n
is only used on Windows Notepad, the DOS command line, most of the Windows API and in some (older) Windows apps.\n
is used for all other systems, applications and the Internet.You'll notice that I've put most Windows apps in the \n
group which may be slightly controversial but before you disagree with this statement, please grab a UNIX formatted text file and try it in 10 web friendly Windows applications of your choice (which aren't listed in my exceptions above). What percentage of them handled it just fine? You'll find that they (practically) all implement auto detection of line endings or just use \n
because, while Windows may use \r\n
, the Internet uses \n
. Therefore, it is best practice for applications to use \n
alone if you want your output to be Internet friendly.
PHP also defines a newline character called PHP_EOL
. This constant is set to the OS specific newline string for the machine PHP is running on (\r\n
for Windows and \n
for everything else). This constant is not very useful for webpages and should be avoided for HTML output or for writing most text to files. It becomes VERY useful when we move to command line output from PHP applications because it will allow your application to output to a terminal Window in a consistent manner across all supported OSes.
If you want your PHP applications to work from any server they are placed on, the two biggest things to remember are that you should always just use \n
unless it is terminal output (in which case you use PHP_EOL) and you should also ALWAYS use /
for your path separator (not \
).
The even longer explanation:
An application may choose to use whatever line endings it likes regardless of the default OS line ending style. If I want my text editor to print a newline every time it encounters a period that is no harder than using the \n
to represent a newline because I'm interpreting the text as I display it anyway. IOW, I'm fiddling around with measuring the width of each character so it knows where to display the next so it is very simple to add a statement saying that if the current char is a period then perform a newline action (or if it is a \n
then display a period).
Aside from the null terminator, no character code is sacred and when you write a text editor or viewer you are in charge of translating the bits in your file into glyphs (or carriage returns) on the screen. The only thing that distinguishes a control character such as the newline from other characters is that most font sets don't include them (meaning they don't have a visual representation available).
That being said, if you are working at a higher level of abstraction then you probably aren't making your own textbox controls. If this is the case then you're stuck with whatever line ending that control makes available to you. Even in this case it is a simple matter to automatically detect the line ending style of any string and make the conversion before you load your text into the control and then undo it when you read from that control. Meaning, that if you're a desktop application dev and your application doesn't recognize \n
as a newline then it isn't a very friendly application and you really have no excuse because it isn't hard to make it the right way. It also means that whomever wrote Notepad should be ashamed of himself because it really is very easy to do much better and so many people suffer through using it every day.
Just for completeness, there is also the LINQ/Lambda way:
myMoney.ForEach((theMoney) => Console.WriteLine("amount is {0}, and type is {1}", theMoney.amount, theMoney.type));
I highly recommend you use the tobytes
function of the Image
object. After some timing checks this is much more efficient.
def jpg_image_to_array(image_path):
"""
Loads JPEG image into 3D Numpy array of shape
(width, height, channels)
"""
with Image.open(image_path) as image:
im_arr = np.fromstring(image.tobytes(), dtype=np.uint8)
im_arr = im_arr.reshape((image.size[1], image.size[0], 3))
return im_arr
The timings I ran on my laptop show
In [76]: %timeit np.fromstring(im.tobytes(), dtype=np.uint8)
1000 loops, best of 3: 230 µs per loop
In [77]: %timeit np.array(im.getdata(), dtype=np.uint8)
10 loops, best of 3: 114 ms per loop
```

As you're passing true as the second parameter to json_decode
, in the above example you can retrieve data doing something similar to:
<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
var_dump(json_decode($json, true));
?>
Might be a little late with the answer but you need to supply the MIME type attribute in the video tag: type="application/x-mpegURL". The video tag I use for a 16:9 stream looks like this.
<video width="352" height="198" controls>
<source src="playlist.m3u8" type="application/x-mpegURL">

Maybe this small Typescript code example will help.
private getAccount(id: Id) : Account {
let account = Account.empty();
this.repository.get(id)
.then(res => account = res)
.catch(e => Notices.results(e));
return account;
}
Here the repository.get(id)
returns a Promise<Account>
. I assign it to the variable account
within the then
statement.
I know this is an older post, but I spent a long time trying to find a solution. I came across a decent one using only ReportLab and PyPDF so I thought I'd share:
PdfFileReader()
, we'll call this inputPdfFileReader()
, we'll call this textPdfFileWriter()
, we'll call this output.mergePage(*text*.getPage(0))
for each page you want the text added to, then use output.addPage()
to add the modified pages to a new documentThis works well for simple text additions. See PyPDF's sample for watermarking a document.
Here is some code to answer the question below:
packet = StringIO.StringIO()
can = canvas.Canvas(packet, pagesize=letter)
<do something with canvas>
can.save()
packet.seek(0)
input = PdfFileReader(packet)
From here you can merge the pages of the input file with another document.
If you are on Mac OS X you can write:
NSString* s = [[NSDate date] descriptionWithCalendarFormat:@"%Y_%m_%d_%H_%M_%S" timeZone:nil locale:nil];
However this is not available on iOS.
Well, all could be temporary hacks, but there is no way to get mobile number of a user. It is against ethical policy.
For eg, one of the answers above suggests getting all accounts and extracting from there. And it doesn't work anymore! All of these are hacks only.
Only way to get user's mobile number is going through operator. If you have a tie-up with mobile operators like Aitel, Vodafone, etc, you can get user's mobile number in header of request from mobile handset when connected via mobile network internet.
Not sure if any manufacturer tie ups to get specific permissions can help - not explored this area, but nothing documented atleast.

The ASPX code will look something like this:
<asp:RadioButtonList ID="rblist1" runat="server">

<asp:ListItem Text ="Item2" Value="2" />
<asp:ListItem Text ="Item3" Value="3" />
<asp:ListItem Text ="Item4" Value="4" />
</asp:RadioButtonList>
<asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="select value" />
And the code behind:
protected void Button1_Click(object sender, EventArgs e)
{
string selectedValue = rblist1.SelectedValue;
Response.Write(selectedValue);
}
Using =
causes the variable to be assigned a value. If the variable already had a value, it is replaced. This value will be expanded when it is used. For example:
HELLO = world
HELLO_WORLD = $(HELLO) world!
# This echoes "world world!"
echo $(HELLO_WORLD)
HELLO = hello
# This echoes "hello world!"
echo $(HELLO_WORLD)
Using :=
is similar to using =
. However, instead of the value being expanded when it is used, it is expanded during the assignment. For example:
HELLO = world
HELLO_WORLD := $(HELLO) world!
# This echoes "world world!"
echo $(HELLO_WORLD)
HELLO = hello
# Still echoes "world world!"
echo $(HELLO_WORLD)
HELLO_WORLD := $(HELLO) world!
# This echoes "hello world!"
echo $(HELLO_WORLD)
Using ?=
assigns the variable a value iff the variable was not previously assigned. If the variable was previously assigned a blank value (VAR=
), it is still considered set I think. Otherwise, functions exactly like =
.
Using +=
is like using =
, but instead of replacing the value, the value is appended to the current one, with a space in between. If the variable was previously set with :=
, it is expanded I think. The resulting value is expanded when it is used I think. For example:
HELLO_WORLD = hello
HELLO_WORLD += world!
# This echoes "hello world!"
echo $(HELLO_WORLD)
If something like HELLO_WORLD = $(HELLO_WORLD) world!
were used, recursion would result, which would most likely end the execution of your Makefile. If A := $(A) $(B)
were used, the result would not be the exact same as using +=
because B
is expanded with :=
whereas +=
would not cause B
to be expanded.

upstream
in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add
. Depending on what you select for this name, your git pull
usage will change. For example, if you use:
git remote add upstream git://github.com/somename/original-project.git
then you would use this to pull changes:
git pull upstream master
But, if you choose origin for the name of the remote repo, your commands would be:
To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git
And to pull: git pull origin master

virtualenv env_name --python="python3"
and run the following command
pip3 install opencv-python
This is how i have done it:
using (HttpClient httpClient = new HttpClient())
{
Dictionary<string, string> tokenDetails = null;
var messageDetails = new Message { Id = 4, Message1 = des };
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:3774/");
var login = new Dictionary<string, string>
{
{"grant_type", "password"},
{"username", "[email protected]"},
{"password", "lopzwsx@23"},
};
var response = client.PostAsync("Token", new FormUrlEncodedContent(login)).Result;
if (response.IsSuccessStatusCode)
{
tokenDetails = JsonConvert.DeserializeObject<Dictionary<string, string>>(response.Content.ReadAsStringAsync().Result);
if (tokenDetails != null && tokenDetails.Any())
{
var tokenNo = tokenDetails.FirstOrDefault().Value;
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + tokenNo);
client.PostAsJsonAsync("api/menu", messageDetails)
.ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());
}
}
}

I have executed the code in my machine its working for IE and FF also.
function closeSelf(){
// do something
if(condition satisfied){
alert("conditions satisfied, submiting the form.");
document.forms['certform'].submit();
window.close();
}else{
alert("conditions not satisfied, returning to form");
}
}

<div>Certificate 3: <input type="file" name="cert3"/></div>
// change the submit button to normal button
<div><input type="button" value="Upload" onclick="closeSelf();"/></div>

I was able to get what I needed using Martinho Fernandes' solution below. The code is:
var test = "My cow always gives milk";
var testRE = test.match("cow(.*)milk");
alert(testRE[1]);
You'll notice that I am alerting the testRE variable as an array. This is because testRE is returning as an array, for some reason. The output from:
My cow always gives milk
Changes into:
always gives
In SVG (contrasted with HTML), you will want to use <image>
instead of <img>
for elements.
Try changing your last block with:
var imgs = svg.selectAll("image").data([0]);
imgs.enter()
.append("svg:image")

Here is snippet that allowed me to log out programmatically from facebook. Let me know if you see anything that I might need to improve.
private void logout(){
// clear any user information
mApp.clearUserPrefs();
// find the active session which can only be facebook in my app
Session session = Session.getActiveSession();
// run the closeAndClearTokenInformation which does the following
// DOCS : Closes the local in-memory Session object and clears any persistent
// cache related to the Session.
session.closeAndClearTokenInformation();
// return the user to the login screen
startActivity(new Intent(getApplicationContext(), LoginActivity.class));
// make sure the user can not access the page after he/she is logged out
// clear the activity stack
finish();
}

For me there was a problem with the terminal encoding. Adding UTF-8 to .bashrc solved the problem:
export LC_CTYPE=en_US.UTF-8
Don't forget to reload .bashrc afterwards:
source ~/.bashrc
What you want is .empty
not .empty()
to fully mimics Ruby :
Object.defineProperty( Array.prototype, 'empty', {
get: function ( ) { return this.length===0 }
} );
then
[].empty //true
[3,2,8].empty //false
For any , see my answer here
The following code allows you Python 2/3 compatibility:
try:
reload
except NameError:
# Python 3
from imp import reload
The you can use it as reload()
in both versions which makes things simpler.
i've used the $templateCache to accomplish something similar. i put several ng-templates in a single html file, which i reference using the directive's templateUrl. that ensures the html is available to the template cache. then i can simply select by id to get the ng-template i want.
template.html:
<script type="text/ng-template" id=“foo”>
foo
</script>
<script type="text/ng-template" id=“bar”>
bar
</script>
directive:
myapp.directive(‘foobardirective’, ['$compile', '$templateCache', function ($compile, $templateCache) {
var getTemplate = function(data) {
// use data to determine which template to use
var templateid = 'foo';
var template = $templateCache.get(templateid);
return template;
}
return {
templateUrl: 'views/partials/template.html',
scope: {data: '='},
restrict: 'E',
link: function(scope, element) {
var template = getTemplate(scope.data);
element.html(template);
$compile(element.contents())(scope);
}
};
}]);
There's a problem with immediate asynchronous call of your function, because standard setTimeout/setInterval has a minimal timeout about several milliseconds even if you directly set it to 0. It caused by a browser specific work.
An example of code with a REAL zero delay wich works in Chrome, Safari, Opera
function setZeroTimeout(callback) {
var channel = new MessageChannel();
channel.port1.onmessage = callback;
channel.port2.postMessage('');
}
You can find more information here
And after the first manual call you can create an interval with your function.
If you want your application to open the link in a web browser you need to add a HyperLink with the RequestNavigate event set to a function that programmatically opens a web-browser with the address as a parameter.
<TextBlock>
<Hyperlink NavigateUri="http://www.google.com" RequestNavigate="Hyperlink_RequestNavigate">
Click here
</Hyperlink>
</TextBlock>
In the code-behind you would need to add something similar to this to handle the RequestNavigate event:
private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
// for .NET Core you need to add UseShellExecute = true
// see https://docs.microsoft.com/dotnet/api/system.diagnostics.processstartinfo.useshellexecute#property-value
Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
e.Handled = true;
}
In addition you will also need the following imports:
using System.Diagnostics;
using System.Windows.Navigation;
It will look like this in your application:
None of the current solutions worked for me with git bash 2.26.2. This should work in any case if you are using the windows credential manager.
One issue is the windows credential manager runs for the logged user. In my case for example, I run git bash with right click, run as admin. Therefore, my stored credentials are in a credentials manager which I can't access with the windows GUI if I don't login to windows as admin.
To fix this:
cmdkey /list
. Your old credentials should appear here, with a part that reads ...target:xxx...cmdkey /delete:xxx
, where xxx is the target from the previous lineIt should confirm you that your credentials have been removed. Next time you do any operation in git bash that requires authentication, a popup will ask for your credentials.
I think this may be what you are looking for: ON CONFLICT clause.
If you define your table like this:
CREATE TABLE table1(
id INTEGER PRIMARY KEY ON CONFLICT REPLACE,
field1 TEXT
);
Now, if you do an INSERT with an id that already exists, SQLite automagically does UPDATE instead of INSERT.

(alias: gc
) is your usual option for reading a text file. You can then filter further:
gc log.txt | select -first 10 # head
gc -TotalCount 10 log.txt # also head
gc log.txt | select -last 10 # tail
gc -Tail 10 log.txt # also tail (since PSv3), also much faster than above option
gc log.txt | more # or less if you have it installed
gc log.txt | %{ $_ -replace '\d+', '($0)' } # sed
This works well enough for small files, larger ones (more than a few MiB) are probably a bit slow.
The PowerShell Community Extensions include some cmdlets for specialised file stuff (e.g. Get-FileTail).
Roman's answer worked fine for me - or at least, it gave me what I was expecting. Opening the video in the phone's native application is exactly the same as what the iPhone does.
It's probably worth adjusting your viewpoint and expect video to be played fullscreen in its own application, and coding for that. It's frustrating that clicking the video isn't sufficient to get it playing in the same way as the iPhone does, but seeing as it only takes an onclick attribute to launch it, it's not the end of the world.
My advice, FWIW, is to use a poster image, and make it obvious that it will play the video. I'm working on a project at the moment that does precisely that, and the clients are happy with it - and also that they're getting the Android version of a web app for free, of course, because the contract was only for an iPhone web app.
Just for illustration, a working Android video tag is below. Nice and simple.
<video src="video/placeholder.m4v" poster="video/placeholder.jpg" onclick="this.play();"/>
Do you want to delete a variable, don't you?
ok, I think I've got a best alternative idea to @bnaul's answer:
You can delete individual names with del
:
del x
or you can remove them from the globals()
object:
for name in dir():
if not name.startswith('_'):
del globals()[name]
This is just an example loop; it defensively only deletes names that do not start with an underscore, making a (not unreasoned) assumption that you only used names without an underscore at the start in your interpreter. You could use a hard-coded list of names to keep instead (whitelisting) if you really wanted to be thorough. There is no built-in function to do the clearing for you, other than just exit and restart the interpreter.
Modules you've imported (like import os
) are going to remain imported because they are referenced by sys.modules
; subsequent imports will reuse the already imported module object. You just won't have a reference to them in your current global namespace.
You can set a layout manager like BorderLayout and then define more specifically, where your panel should go:
MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new BorderLayout());
mainFrame.add(mainPanel, BorderLayout.CENTER);
mainFrame.pack();
mainFrame.setVisible(true);
This puts the panel into the center area of the frame and lets it grow automatically when resizing the frame.
This is a simple and maybe not the best solution, but it works.
On the line above the line you get your error, paste this:
// eslint-disable-next-line no-restricted-globals
System.Uri.EscapeUriString()
can be problematic with certain characters, for me it was a number / pound '#' sign in the string.
If that is an issue for you, try:
System.Uri.EscapeDataString() //Works excellent with individual values
Here is a SO question answer that explains the difference:
What's the difference between EscapeUriString and EscapeDataString?
and recommends to use Uri.EscapeDataString()
in any aspect.
While Shannon's answer is technically correct, it looks like overkill.
The simple solution is that you need to put your summation outside of the case
statement.
This should do the trick:
sum(CASE WHEN col1 > col2 THEN col3*col4 ELSE 0 END) AS some_product
Basically, your old code tells SQL to execute the sum(X*Y)
for each line individually (leaving each line with its own answer that can't be grouped).
The code line I have written takes the sum product, which is what you want.
By encode, do you mean: Convert all applicable characters to HTML entities?
htmlspecialchars
or
htmlentities
You can also use strip_tags if you want to remove all HTML tags :
Note: this will NOT stop all XSS attacks
In static class, if you are getting information from xml or reg, class tries to initialize all properties. therefore, you should control if the config variable is there otherwise properties will not initialize so the class.
Check xml referance variable is there, Check reg referance variable is is there, Make sure you handle if they are not there.
You shouldn't use float unless you have to. In 99% of cases, double is a better choice.
int x = 1111111111;
int y = 10000;
float f = (float) x / y;
double d = (double) x / y;
System.out.println("f= "+f);
System.out.println("d= "+d);
prints
f= 111111.12
d= 111111.1111
Following @Matt's comment.
float has very little precision (6-7 digits) and shows significant rounding error fairly easily. double has another 9 digits of accuracy. The cost of using double instead of float is notional in 99% of cases however the cost of a subtle bug due to rounding error is much higher. For this reason, many developers recommend not using floating point at all and strongly recommend BigDecimal.
However I find that double can be used in most cases provided sensible rounding is used.
In this case, int x has 32-bit precision whereas float has a 24-bit precision, even dividing by 1 could have a rounding error. double on the other hand has 53-bit of precision which is more than enough to get a reasonably accurate result.
If you are using Windows, the virtual machine should have it's own process that is visible in task manager. Use sysinternals Process Explorer to find the right one and then kill it from there.
If you are searching by the fieldname1
value, try this:
var r = exitDictionary
.Select(i => i.Value).Cast<Dictionary<string, object>>()
.Where(d => d.ContainsKey("fieldname1"))
.Select(d => d["fieldname1"]).Cast<List<Dictionary<string, string>>>()
.SelectMany(d1 =>
d1
.Where(d => d.ContainsKey("valueTitle"))
.Select(d => d["valueTitle"])
.Where(v => v != null)).ToList();
If you are looking by the type of the value in the subDictionary
(Dictionary<string, object>
explicitly), you may do this:
var r = exitDictionary
.Select(i => i.Value).Cast<Dictionary<string, object>>()
.SelectMany(d=>d.Values)
.OfType<List<Dictionary<string, string>>>()
.SelectMany(d1 =>
d1
.Where(d => d.ContainsKey("valueTitle"))
.Select(d => d["valueTitle"])
.Where(v => v != null)).ToList();
Both alternatives will return:
title1
title2
title3
title1
title2
title3

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray()
According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.
This will work for you:
$phpExcel = new PHPExcel();
$styleArray = array(
'font' => array(
'bold' => true,
'color' => array('rgb' => 'FF0000'),
'size' => 15,
'name' => 'Verdana'
));
$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);
To apply font style to complete excel document:
$styleArray = array(
'font' => array(
'bold' => true,
'color' => array('rgb' => 'FF0000'),
'size' => 15,
'name' => 'Verdana'
));
$phpExcel->getDefaultStyle()
->applyFromArray($styleArray);

In Chrome (possible Safari too) you can inspect an element, then right click on the tag you want to get the xpath for, then you can copy the xpath to select that element.
Since C++11 you can use std::chrono
:
std::chrono::system_clock::now()
.time_since_epoch()
duration_cast<milliseconds>(d)
std::chrono::milliseconds
to integer (uint64_t
to avoid overflow)#include <chrono>
#include <cstdint>
#include <iostream>
uint64_t timeSinceEpochMillisec() {
using namespace std::chrono;
return duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();
}
int main() {
std::cout << timeSinceEpochMillisec() << std::endl;
return 0;
}
For completeness, guava also has a handy utility for this
ByteStreams.copy(input, output);
The easiest way is probably with VLOOKUP()
. This will require the 2nd worksheet to have the employee number column sorted though. In newer versions of Excel, apparently sorting is no longer required.
For example, if you had a "Sheet2" with two columns - A = the employee number, B = the employee's name, and your current worksheet had employee numbers in column D and you want to fill in column E, in cell E2, you would have:
=VLOOKUP($D2, Sheet2!$A$2:$B$65535, 2, FALSE)
Then simply fill this formula down the rest of column D.
Explanation:
$D2
specifies the value to search for.Sheet2!$A$2:$B$65535
specifies the range of cells to search in. Excel will search for the value in the first column of this range (in this case Sheet2!A2:A65535
). Note I am assuming you have a header cell in row 1.2
specifies a 1-based index of the column to return from within the searched range. The value of 2
will return the second column in the range Sheet2!$A$2:$B$65535
, namely the value of the B
column.FALSE
says to only return exact matches.I'm not sure precisely what you're looking for, but this program:

new Building () { Name = "one", Status = Building.StatusType.open },
new Building () { Name = "two", Status = Building.StatusType.closed },
new Building () { Name = "three", Status = Building.StatusType.weird },
new Building () { Name = "four", Status = Building.StatusType.open },
new Building () { Name = "five", Status = Building.StatusType.closed },
new Building () { Name = "six", Status = Building.StatusType.weird },
};
static void Main (string [] args)
{
var statusList = new List<Building.StatusType> () { Building.StatusType.open, Building.StatusType.closed };
var q = from building in buildingList
where statusList.Contains (building.Status)
select building;
foreach ( var b in q )
Console.WriteLine ("{0}: {1}", b.Name, b.Status);
}
produces the expected output:
one: open
two: closed
four: open
five: closed
This program compares a string representation of the enum and produces the same output:
public class Building
{
public enum StatusType
{
open,
closed,
weird,
};
public string Name { get; set; }
public string Status { get; set; }
}
public static List <Building> buildingList = new List<Building> ()
{
new Building () { Name = "one", Status = "open" },
new Building () { Name = "two", Status = "closed" },
new Building () { Name = "three", Status = "weird" },
new Building () { Name = "four", Status = "open" },
new Building () { Name = "five", Status = "closed" },
new Building () { Name = "six", Status = "weird" },
};
static void Main (string [] args)
{
var statusList = new List<Building.StatusType> () { Building.StatusType.open, Building.StatusType.closed };
var statusStringList = statusList.ConvertAll <string> (st => st.ToString ());
var q = from building in buildingList
where statusStringList.Contains (building.Status)
select building;
foreach ( var b in q )
Console.WriteLine ("{0}: {1}", b.Name, b.Status);
Console.ReadKey ();
}
I created this extension method to convert one IEnumerable to another, but I'm not sure how efficient it is; it may just create a list behind the scenes.
public static IEnumerable <TResult> ConvertEach (IEnumerable <TSource> sources, Func <TSource,TResult> convert)
{
foreach ( TSource source in sources )
yield return convert (source);
}
Then you can change the where clause to:
where statusList.ConvertEach <string> (status => status.GetCharValue()).
Contains (v.Status)
and skip creating the List<string>
with ConvertAll ()
at the beginning.
printf("%02X:%02X:%02X:%02X", buf[0], buf[1], buf[2], buf[3]);
for a more generic way:
int i;
for (i = 0; i < x; i++)
{
if (i > 0) printf(":");
printf("%02X", buf[i]);
}
printf("\n");
to concatenate to a string, there are a few ways you can do this... i'd probably keep a pointer to the end of the string and use sprintf. you should also keep track of the size of the array to make sure it doesnt get larger than the space allocated:
int i;
char* buf2 = stringbuf;
char* endofbuf = stringbuf + sizeof(stringbuf);
for (i = 0; i < x; i++)
{
/* i use 5 here since we are going to add at most
3 chars, need a space for the end '\n' and need
a null terminator */
if (buf2 + 5 < endofbuf)
{
if (i > 0)
{
buf2 += sprintf(buf2, ":");
}
buf2 += sprintf(buf2, "%02X", buf[i]);
}
}
buf2 += sprintf(buf2, "\n");
As reported in https://github.com/angular/angular.js/issues/4765, switching from ng-click to ng-change seems to fix this (I am using Angular 1.2.14)
Clip.exe is an executable in Windows to set the clipboard. Note that this does not work for other operating systems other than Windows, which still sucks.
/// <summary>
/// Sets clipboard to value.
/// </summary>
/// <param name="value">String to set the clipboard to.</param>
public static void SetClipboard(string value)
{
if (value == null)
throw new ArgumentNullException("Attempt to set clipboard with null");
Process clipboardExecutable = new Process();
clipboardExecutable.StartInfo = new ProcessStartInfo // Creates the process
{
RedirectStandardInput = true,
FileName = @"clip",
};
clipboardExecutable.Start();
clipboardExecutable.StandardInput.Write(value); // CLIP uses STDIN as input.
// When we are done writing all the string, close it so clip doesn't wait and get stuck
clipboardExecutable.StandardInput.Close();
return;
}
Try this,
1. If you want to skip a particular iteration, use continue.
2. If you want to break out of the immediate loop use break
3 If there are 2 loop, outer and inner.... and you want to break out of both the loop from
the inner loop, use break with label.
eg:
continue
for(int i=0 ; i<5 ; i++){
if (i==2){
continue;
}
}
eg:
break
for(int i=0 ; i<5 ; i++){
if (i==2){
break;
}
}
eg:
break with label
lab1: for(int j=0 ; j<5 ; j++){
for(int i=0 ; i<5 ; i++){
if (i==2){
break lab1;
}
}
}
let $timeoutPromise = null;
$timeout.cancel($timeoutPromise);
$timeoutPromise = $timeout(() => {
$scope.$digest();
}, 0, false);
Here is good solution to avoid this error and avoid $apply
you can combine this with debounce(0) if calling based on external event. Above is the 'debounce' we are using, and full example of code
.factory('debounce', [
'$timeout',
function ($timeout) {
return function (func, wait, apply) {
// apply default is true for $timeout
if (apply !== false) {
apply = true;
}
var promise;
return function () {
var cntx = this,
args = arguments;
$timeout.cancel(promise);
promise = $timeout(function () {
return func.apply(cntx, args);
}, wait, apply);
return promise;
};
};
}
])
and the code itself to listen some event and call $digest only on $scope you need
let $timeoutPromise = null;
let $update = debounce(function () {
$timeout.cancel($timeoutPromise);
$timeoutPromise = $timeout(() => {
$scope.$digest();
}, 0, false);
}, 0, false);
let $unwatchModelChanges = $scope.$root.$on('updatePropertiesInspector', function () {
$update();
});
$scope.$on('$destroy', () => {
$timeout.cancel($update);
$timeout.cancel($timeoutPromise);
$unwatchModelChanges();
});
If you try to decrypt PKCS5-padded data with the wrong key, and then unpad it (which is done by the Cipher class automatically), you most likely will get the BadPaddingException (with probably of slightly less than 255/256, around 99.61%), because the padding has a special structure which is validated during unpad and very few keys would produce a valid padding.
So, if you get this exception, catch it and treat it as "wrong key".
This also can happen when you provide a wrong password, which then is used to get the key from a keystore, or which is converted into a key using a key generation function.
Of course, bad padding can also happen if your data is corrupted in transport.
That said, there are some security remarks about your scheme:
For password-based encryption, you should use a SecretKeyFactory and PBEKeySpec instead of using a SecureRandom with KeyGenerator. The reason is that the SecureRandom could be a different algorithm on each Java implementation, giving you a different key. The SecretKeyFactory does the key derivation in a defined manner (and a manner which is deemed secure, if you select the right algorithm).
Don't use ECB-mode. It encrypts each block independently, which means that identical plain text blocks also give always identical ciphertext blocks.
Preferably use a secure mode of operation, like CBC (Cipher block chaining) or CTR (Counter). Alternatively, use a mode which also includes authentication, like GCM (Galois-Counter mode) or CCM (Counter with CBC-MAC), see next point.
You normally don't want only confidentiality, but also authentication, which makes sure the message is not tampered with. (This also prevents chosen-ciphertext attacks on your cipher, i.e. helps for confidentiality.) So, add a MAC (message authentication code) to your message, or use a cipher mode which includes authentication (see previous point).
DES has an effective key size of only 56 bits. This key space is quite small, it can be brute-forced in some hours by a dedicated attacker. If you generate your key by a password, this will get even faster. Also, DES has a block size of only 64 bits, which adds some more weaknesses in chaining modes. Use a modern algorithm like AES instead, which has a block size of 128 bits, and a key size of 128 bits (for the standard variant).

As a parameter you can pass an exit code, which will be returned to OS. Default is 0.
title
attributeHow the text in the title
attribute is displayed is defined by the browser and varies from browser to browser. It's not possible for a webpage to apply any style to the tooltip that the browser displays based on the title
attribute.
However, you can create something very similar using other attributes.
data-title
)For this, I'd use a data-title
attribute. data-*
attributes are a method to store custom data in DOM elements/HTML. There are multiple ways of accessing them. Importantly, they can be selected by CSS.
Given that you can use CSS to select elements with data-title
attributes, you can then use CSS to create :after
(or :before
) content
that contains the value of the attribute using attr()
.

Unlike a real title
tooltip, the tooltip produced by the above CSS is not, necessarily, guaranteed to be visible on the page (i.e. it might be outside the visible area). On the other hand, it is guaranteed to be within the current window, which is not the case for an actual tooltip.
In addition, the pseudo-tooltip is positioned relative to the element that has the pseudo-tooltip rather than relative to where the mouse is on that element. You may want to fine-tune where the pseudo-tooltip is displayed. Having it appear in a known location relative to the element can be a benefit or a drawback, depending on the situation.
:before
or :after
on elements which are not containersThere's a good explanation in this answer to "Can I use a :before or :after pseudo-element on an input field?"
Effectively, this means that you can't use this method directly on elements like <input type="text"/>
, <textarea/>
, <img>
, etc. The easy solution is to wrap the element that's not a container in a <span>
or <div>
and have the pseudo-tooltip on the container.
Examples of using a pseudo-tooltip on a <span>
wrapping a non-container element:
[data-title]:hover:after {_x000D_

transition: all 0.1s ease 0.5s;_x000D_

From the code on the blog post linked above (which I first saw in an answer here that plagiarized it), it appeared obvious to me to use a data-*
attribute instead of the title
attribute. Doing so was also suggested in a comment by snostorm on that (now deleted) answer.
Try this:
Use back-ticks for NAME
CREATE TABLE `teachers` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(50) NOT NULL,
`addr` varchar(255) NOT NULL,
`phone` int(10) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
For memory usage, the following will work,
long total = Runtime.getRuntime().totalMemory();
long used = Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory();
For CPU usage, you'll need to use an external application to measure it.
If you use the following instead:
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
The TRUE returns an array instead of an object.
Why not this:
rsq <- function(x, y) summary(lm(y~x))$r.squared
rsq(obs, mod)
#[1] 0.8560185
Older MySQL versions this is enough:
SELECT
`userName`,
`carPrice`
FROM `users`
LEFT JOIN (SELECT * FROM `cars` ORDER BY `carPrice`) as `cars`
ON cars.belongsToUser=users.id
WHERE `id`='4'
Nowdays, if you use MariaDB the subquery should be limited.
SELECT
`userName`,
`carPrice`
FROM `users`
LEFT JOIN (SELECT * FROM `cars` ORDER BY `carPrice` LIMIT 18446744073709551615) as `cars`
ON cars.belongsToUser=users.id
WHERE `id`='4'
You can use the storage_path();
function to get storage folder path.
storage_path(); // Return path like: laravel_app\storage
Suppose you want to save your logfile mylog.log
inside Log folder of storage folder. You have to write something like
storage_path() . '/LogFolder/mylog.log'
I faced the same error, but only with files cloned from git that were assigned to a proprietary plugin. I realized that even after cloning the files from git, I needed to create a new project or import a project in eclipse and this resolved the error.
You could use the RedirectMatch directive in Apache to do something similar you want.
It's pretty simple.
RedirectMatch / http://222.222.222.222/
Anyway, I can't see any reason to do that thing. Aren't you trying to intercept traffic? There are better ways. For Linux boxes as a router: iptables -j REDIRECT + Squid or Apache. For Cisco routers, you can use WCCP to a Cache or Web Server...
(Under Linux), I wanted to use the posts here suggesting the ls-files --ignored --exclude-standard | xargs git rm -r --cached
approach. However, (some of) the files to be removed had an embedded newline/LF/\n
in their names. Neither of the solutions:
git ls-files --ignored --exclude-standard | xargs -d"\n" git rm --cached
git ls-files --ignored --exclude-standard | sed 's/.*/"&"/' | xargs git rm -r --cached
cope with this situation (get errors about files not found).
git ls-files -z --ignored --exclude-standard | xargs -0 git rm -r --cached
git commit -am "Remove ignored files"
This uses the -z
argument to ls-files, and the -0
argument to xargs to cater safely/correctly for "nasty" characters in filenames.
In the manual page git-ls-files(1), it states:
When -z option is not used, TAB, LF, and backslash characters in pathnames are represented as \t, \n, and \\, respectively.
so I think my solution is needed if filenames have any of these characters in them.
UIButton with constraints in iOS 9.1/Xcode 7.1.1/Swift 2.1
:
import UIKit
import MapKit
class MapViewController: UIViewController {
override func loadView() {
mapView = MKMapView() //Create a view...
view = mapView //assign it to the ViewController's (inherited) view property.
//Equivalent to self.view = mapView
myButton = UIButton(type: .RoundedRect) //RoundedRect is an alias for System (tested by printing out their rawValue's)
//myButton.frame = CGRect(x:50, y:500, width:70, height:50) //Doesn't seem to be necessary when using constraints.
myButton.setTitle("Current\nLocation", forState: .Normal)
myButton.titleLabel?.lineBreakMode = .ByWordWrapping //If newline in title, split title onto multiple lines
myButton.titleLabel?.textAlignment = .Center
myButton.setTitleColor(UIColor.whiteColor(), forState: .Normal)
myButton.layer.cornerRadius = 6 //For some reason, a button with type RoundedRect has square corners
myButton.backgroundColor = UIColor.redColor().colorWithAlphaComponent(0.5) //Make the color partially transparent
//Attempt to add padding around text. Shrunk the frame when I tried it. Negative values had no effect.
//myButton.titleEdgeInsets = UIEdgeInsetsMake(-10,-10,-10,-10)
myButton.contentEdgeInsets = UIEdgeInsetsMake(5,5,5,5) //Add padding around text.
myButton.addTarget(self, action: "getCurrentLocation:", forControlEvents: .TouchUpInside)
mapView.addSubview(myButton)
//Button Constraints:
myButton.translatesAutoresizingMaskIntoConstraints = false //***
//bottomLayoutGuide(for tab bar) and topLayoutGuide(for status bar) are properties of the ViewController
//To anchor above the tab bar on the bottom of the screen:
let bottomButtonConstraint = myButton.bottomAnchor.constraintEqualToAnchor(bottomLayoutGuide.topAnchor, constant: -20) //Implied call of self.bottomLayoutGuide. Anchor 20 points **above** the top of the tab bar.
//To anchor to the blue guide line that is inset from the left
//edge of the screen in InterfaceBuilder:
let margins = view.layoutMarginsGuide //Now the guide is a property of the View.
let leadingButtonConstraint = myButton.leadingAnchor.constraintEqualToAnchor(margins.leadingAnchor)
bottomButtonConstraint.active = true
leadingButtonConstraint.active = true
}
func getCurrentLocation(sender: UIButton) {
print("Current Location button clicked!")
}
The button is anchored to the bottom left corner, above the tab bar.
Some thing like this should also work

I did a little research through trial and error method. Found out that all the values that are available in keyboard are eligible to be a file or directory except '/' in *nux machine.
I used touch command to create file for following characters and it created a file.
(Comma separated values below)
'!', '@', '#', '$', "'", '%', '^', '&', '*', '(', ')', ' ', '"', '\', '-', ',', '[', ']', '{', '}', '`', '~', '>', '<', '=', '+', ';', ':', '|'
It failed only when I tried creating '/' (because it's root directory) and filename container /
because it file separator.
And it changed the modified time of current dir .
when I did touch .
. However, file.log is possible.
And of course, a-z
, A-Z
, 0-9
, -
(hypen), _
(underscore) should work.
So, by the above reasoning we know that a file name or directory name can contain anything except /
forward slash. So, our regex will be derived by what will not be present in the file name/directory name.
/(?:(?P<dir>(?:[/]?)(?:[^\/]+/)+)(?P<filename>[^/]+))/
root
directoryA directory can start with /
when it is absolute path and directory name when it's relative. Hence, look for /
with zero or one occurrence.
/(?P<filepath>(?P<root>[/]?)(?P<rest_of_the_path>.+))/
Next, a directory and its child is always separated by /
. And a directory name can be anything except /
. Let's match /var/ first then.
/(?P<filepath>(?P<first_directory>(?P<root>[/]?)[^\/]+/)(?P<rest_of_the_path>.+))/
Next, let's match all directories
/(?P<filepath>(?P<dir>(?P<root>[/]?)(?P<single_dir>[^\/]+/)+)(?P<rest_of_the_path>.+))/
Here, single_dir is yz/
because, first it matched var/
, then it found next occurrence of same pattern i.e. log/
, then it found the next occurrence of same pattern yz/
. So, it showed the last occurrence of pattern.
Now, we know that we're never going to use the groups like single_dir, filepath, root. Hence let's clean that up.
Let's keep them as groups however don't capture those groups.
And rest_of_the_path is just the filename! So, rename it. And a file will not have /
in its name, so it's better to keep [^/]
/(?:(?P<dir>(?:[/]?)(?:[^\/]+/)+)(?P<filename>[^/]+))/
This brings us to the final result. Of course, there are several other ways you can do it. I am just mentioning one of the ways here.
^
means string starts with
(?P<dir>pattern)
means capture group by group name. We have two groups with group name dir
and file
(?:pattern)
means don't consider this group or non-capturing group.
?
means match zero or one.
+
means match one or more
[^\/]
means matches any char except forward slash (/
)
[/]?
means if it is absolute path then it can start with / otherwise it won't. So, match zero or one occurrence of /
.
[^\/]+/
means one or more characters which aren't forward slash (/
) which is followed by a forward slash (/
). This will match var/
or xyz/
. One directory at a time.
I've found you can use a very non verbose and straightforward approach to checking for the existence various SQL Server objects this way:
IF OBJECTPROPERTY (object_id('schemaname.scalarfuncname'), 'IsScalarFunction') = 1
IF OBJECTPROPERTY (object_id('schemaname.tablefuncname'), 'IsTableFunction') = 1
IF OBJECTPROPERTY (object_id('schemaname.procname'), 'IsProcedure') = 1
This is based on the OBJECTPROPERTY function which is available in SQL 2005+. The MSDN article can be found here.
The OBJECTPROPERTY function uses the following signature:
OBJECTPROPERTY ( id , property )
You pass a literal value into the property parameter, designating the type of object you are looking for. There's a massive list of values you can supply.
Arrays must have zero based integer indexes in JavaScript. So:
var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);
Or maybe you want to use objects (which are associative arrays):
var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);
which is equivalent to:
var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);
It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.
I needed a variation on this, which I expect will be useful to others:
function diffs() {
diff "${@:3}" <(sort "$1") <(sort "$2")
}
The "${@:3}"
part means all the members of the array starting at 3. So this function implements a sorted diff by passing the first two arguments to diff through sort and then passing all other arguments to diff, so you can call it similarly to diff:
diffs file1 file2 [other diff args, e.g. -y]
What about something like this:
First resample the data frame into 1D intervals. This takes the mean of the values for all duplicate days. Use the fill_method
option to fill in missing date values. Next, pass the resampled frame into pd.rolling_mean
with a window of 3 and min_periods=1 :
pd.rolling_mean(df.resample("1D", fill_method="ffill"), window=3, min_periods=1)
favorable unfavorable other

UPDATE: As Ben points out in the comments, with pandas 0.18.0 the syntax has changed. With the new syntax this would be:
df.resample("1d").sum().fillna(0).rolling(window=3, min_periods=1).mean()
If you want to interpret $replace
, you should not use single quotes since they prevent variable substitution.
Try:
echo $LINE | sed -e "s/12345678/${replace}/g"
Transcript:
pax> export replace=987654321
pax> echo X123456789X | sed "s/123456789/${replace}/"
X987654321X
pax> _
Just be careful to ensure that ${replace}
doesn't have any characters of significance to sed
(like /
for instance) since it will cause confusion unless escaped. But if, as you say, you're replacing one number with another, that shouldn't be a problem.
If you have integers in your file fscanf returns 1 until integer occurs. For example:
FILE *in = fopen("./task.in", "r");
int length = 0;
int counter;
int sequence;
for ( int i = 0; i < 10; i++ ) {
counter = fscanf(in, "%d", &sequence);
if ( counter == 1 ) {
length += 1;
}
}
To find out the end of the file with symbols you can use EOF. For example:
char symbol;
FILE *in = fopen("./task.in", "r");
for ( ; fscanf(in, "%c", &symbol) != EOF; ) {
printf("%c", symbol);
}
I added the spring folder to the build path and, after clean&build, it worked.
Suppose if I have GetAllEmployees.cshtml
<h2>GetAllEmployees</h2>
<p>
<a asp-action="Create">Create New</a>
</p>
<table class="table">
<thead>
// do something ...
</thead>
<tbody>
// do something ...
</tbody>
</table>
//Added my custom scripts in the scripts sections
@section Scripts
{
<script src="~/js/customScripts.js"></script>
}
And another view "GetEmployeeDetails.cshtml" with no scripts
<h2>GetEmployeeByDetails</h2>
@Model.PageTitle
<p>
<a asp-action="Create">Create New</a>
</p>
<table class="table">
<thead>
// do something ...
</thead>
<tbody>
// do something ...
</tbody>
</table>
And my layout page "_layout.cshtml"
@RenderSection("Scripts", required: true)
So, when I navigate to GetEmployeeDetails.cshtml. I get the error that there is no section scripts to be rendered in GetEmployeeDetails.cshtml.
If I change the flag in @RenderSection()
from required : true
to ``required : false`. It means render the scripts defined in the @section scripts of the views if present.Else, do nothing.
And the refined approach would be in _layout.cshtml
@if (IsSectionDefined("Scripts"))
{
@RenderSection("Scripts", required: true)
}
You can use the target
argument in the Thread
constructor to directly pass in a function that gets called instead of run
.
Just click on the "Build" node in the Build Output
From some reason the "Compilation failed" node just started being automatically selected and for that the description window is very unhelpful.
Spaces are used for separating Arguments. In your case C:\Program becomes argument. If your file path contains spaces then add Double quotation marks. Then cmd will recognize it as single argument.
you may try the following code:
mainWindow = new BrowserWindow({
webPreferences: {
nodeIntegration:false,
}
});
node = { 'parent':0, 'left':0, 'right':0 }
import copy
root = copy.deepcopy(node)
root['parent'] = -1
left = copy
just to show another thought on implementation if you stick to the "OOP"
class Node:
def __init__(self,data):
self.data = data
self.child = {}
def append(self, title, child):
self.child[title] = child
CEO = Node( ('ceo', 1000) )
CTO = ('cto',100)
CFO = ('cfo', 10)
CEO.append('left child', CTO)
CEO.append('right child', CFO)
print CEO.data
print ' ', CEO.child['left child']
print ' ', CEO.child['right child']
You could do something like this:
Convert.ToDate(month + " 01, 1900").Month
Here is a version with a timeout so that after an amount of time the loop ends with an error:
# After 60 seconds the loop will exit
timeout=60
while [ ! -f /tmp/list.txt ];
do
# When the timeout is equal to zero, show an error and leave the loop.
if [ "$timeout" == 0 ]; then
echo "ERROR: Timeout while waiting for the file /tmp/list.txt."
exit 1
fi
sleep 1
# Decrease the timeout of one
((timeout--))
done
In Java 8 that parameter is commonly used to print a warning message like this one:
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0
The reason why you get this message in Java 8 is because Permgen has been replaced by Metaspace to address some of PermGen's drawbacks (as you were able to see for yourself, one of those drawbacks is that it had a fixed size).
FYI: an article on Metaspace: http://java-latte.blogspot.in/2014/03/metaspace-in-java-8.html
So, let's say you have this table:
CREATE TABLE YourTable(Col1 VARCHAR(10))
And you want to change Col1
to VARCHAR(20)
. What you need to do is this:
ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)
That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5)
, then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE
will fail.
I followed around five different answers as well as all the blog posts in the previous answers and still had problems. I was trying to add a listener to some existing code that was tracing using the TraceSource.TraceEvent(TraceEventType, Int32, String)
method where the TraceSource
object was initialised with a string making it a 'named source'.
For me the issue was not creating a valid combination of source and switch elements to target this source. Here is an example that will log to a file called tracelog.txt
. For the following code:
TraceSource source = new TraceSource("sourceName");
source.TraceEvent(TraceEventType.Verbose, 1, "Trace message");
I successfully managed to log with the following diagnostics configuration:
<system.diagnostics>
<sources>
<source name="sourceName" switchName="switchName">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="tracelog.txt" />
</listeners>
</source>
</sources>
<switches>
<add name="switchName" value="Verbose" />
</switches>
</system.diagnostics>
Have you looked at this page?
http://www.mongodb.org/display/DOCS/Aggregation#Aggregation-Distinct
That might save you some time?
eg db.addresses.distinct("zip-code");
CORRELATED SUBQUERIES: Is evaluated for each row processed by the Main query. Execute the Inner query based on the value fetched by the Outer query. Continues till all the values returned by the main query are matched. The INNER Query is driven by the OUTER Query
Ex:
SELECT empno,fname,sal,deptid FROM emp e WHERE sal=(SELECT AVG(sal) FROM emp WHERE deptid=e.deptid)
The Correlated subquery specifically computes the AVG(sal)
for each department.
SUBQUERY: Runs first,executed once,returns values to be used by the MAIN Query. The OUTER Query is driven by the INNER QUERY
As of Excel 2019 you could do this. The "Error" at the end is the default.
SWITCH(LEFT(A1,1), "A", "Pick Up", "B", "Collect", "C", "Prepaid", "Error")
C or C++ itself do not define those identifiers. They are compiler extensions and stand for certain calling conventions. That determines where to put arguments, in what order, where the called function will find the return address, and so on. For example, __fastcall means that arguments of functions are passed over registers.
The Wikipedia Article provides an overview of the different calling conventions found out there.
Did you mean len(list1)-1
?
If you're searching for other method, you can try list1.index(list1[-1])
, but I don't recommend this one. You will have to be sure, that the list contains NO duplicates.
all of that is nasty....
ls | grep *.txt | while read file; do cat $file >> ./output.txt; done;

Regarding the differences between json
and jsonb
datatypes, it worth mentioning the official explanation:
PostgreSQL offers two types for storing JSON data:
json
andjsonb
. To implement efficient query mechanisms for these data types, PostgreSQL also provides the jsonpath data type described in Section 8.14.6.The
json
andjsonb
data types accept almost identical sets of values as input. The major practical difference is one of efficiency. Thejson
data type stores an exact copy of the input text, which processing functions must reparse on each execution; whilejsonb
data is stored in a decomposed binary format that makes it slightly slower to input due to added conversion overhead, but significantly faster to process, since no reparsing is needed.jsonb
also supports indexing, which can be a significant advantage.Because the
json
type stores an exact copy of the input text, it will preserve semantically-insignificant white space between tokens, as well as the order of keys within JSON objects. Also, if a JSON object within the value contains the same key more than once, all the key/value pairs are kept. (The processing functions consider the last value as the operative one.) By contrast,jsonb
does not preserve white space, does not preserve the order of object keys, and does not keep duplicate object keys. If duplicate keys are specified in the input, only the last value is kept.In general, most applications should prefer to store JSON data as
jsonb
, unless there are quite specialized needs, such as legacy assumptions about ordering of object keys.PostgreSQL allows only one character set encoding per database. It is therefore not possible for the JSON types to conform rigidly to the JSON specification unless the database encoding is UTF8. Attempts to directly include characters that cannot be represented in the database encoding will fail; conversely, characters that can be represented in the database encoding but not in UTF8 will be allowed.

This is a very simple recursive method to get all files from a given root.
It uses the Java 7 NIO Path class.
private List<String> getFileNames(List<String> fileNames, Path dir) {
try(DirectoryStream<Path> stream = Files.newDirectoryStream(dir)) {
for (Path path : stream) {
if(path.toFile().isDirectory()) {
getFileNames(fileNames, path);
} else {
fileNames.add(path.toAbsolutePath().toString());
System.out.println(path.getFileName());
}
}
} catch(IOException e) {
e.printStackTrace();
}
return fileNames;
}
You can Start the android Service by this command.
adb shell am startservice -n packageName/.ServiceClass
Sure you can. Eg.
<?php
$newsXML = new SimpleXMLElement("<news></news>");
$newsXML->addAttribute('newsPagePrefix', 'value goes here');
$newsIntro = $newsXML->addChild('content');
$newsIntro->addAttribute('type', 'latest');
Header('Content-type: text/xml');
echo $newsXML->asXML();
?>
Output
<?xml version="1.0"?>
<news newsPagePrefix="value goes here">
<content type="latest"/>
</news>
Have fun.
It will run all goals of all configured plugins associated with any phase of the default lifecycle up to the "install" phase:
https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html#Lifecycle_Reference
To get rid of the if/else awkwardness you could use a using block:
@{
var count = 0;
foreach (var item in Model)
{
using(Html.TableRow(new { @class = (count++ % 2 == 0) ? "alt-row" : "" }))
{
<td>
@Html.DisplayFor(modelItem => item.Title)
</td>
<td>
@Html.Truncate(item.Details, 75)
</td>
<td>
<img src="@Url.Content("~/Content/Images/Projects/")@item.Images.Where(i => i.IsMain == true).Select(i => i.Name).Single()"
alt="@item.Images.Where(i => i.IsMain == true).Select(i => i.AltText).Single()" class="thumb" />
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=item.ProjectId }) |
@Html.ActionLink("Details", "Details", new { id = item.ProjectId }) |
@Html.ActionLink("Delete", "Delete", new { id=item.ProjectId })
</td>
}
}
}
Reusable element that make it easier to add attributes:
//Block is take from http://www.codeducky.org/razor-trick-using-block/
public class TableRow : Block
{
private object _htmlAttributes;
private TagBuilder _tr;
public TableRow(HtmlHelper htmlHelper, object htmlAttributes) : base(htmlHelper)
{
_htmlAttributes = htmlAttributes;
}
public override void BeginBlock()
{
_tr = new TagBuilder("tr");
_tr.MergeAttributes(HtmlHelper.AnonymousObjectToHtmlAttributes(_htmlAttributes));
this.HtmlHelper.ViewContext.Writer.Write(_tr.ToString(TagRenderMode.StartTag));
}
protected override void EndBlock()
{
this.HtmlHelper.ViewContext.Writer.Write(_tr.ToString(TagRenderMode.EndTag));
}
}
Helper method to make razor syntax clearer:
public static TableRow TableRow(this HtmlHelper self, object htmlAttributes)
{
var tableRow = new TableRow(self, htmlAttributes);
tableRow.BeginBlock();
return tableRow;
}
Use localhost
instead of your IP address.
e.g,
$myServer = "localhost";
And also double check your mysql username and password.
Since the currently proposed implementations which do implement a sorted list by breaking the Collection API, have an own implementation of a tree or something similar, I was curios how an implementation based on the TreeMap would perform. (Especialy since the TreeSet does base on TreeMap, too)
If someone is interested in that, too, he or she can feel free to look into it:
Its part of the core library, you can add it via Maven dependency of course. (Apache License)
Currently the implementation seems to compare quite well on the same level than the guava SortedMultiSet and to the TreeList of the Apache Commons library.
But I would be happy if more than only me would test the implementation to be sure I did not miss something important.
Best regards!
WordPress overrides PHP's memory limit to 256M, with the assumption that whatever it was set to before is going to be too low to render the dashboard. You can override this by defining WP_MAX_MEMORY_LIMIT
in wp-config.php
:
define( 'WP_MAX_MEMORY_LIMIT' , '512M' );
I agree with DanFromGermany, 256M is really a lot of memory for rendering a dashboard page. Changing the memory limit is really putting a bandage on the problem.
This implementation uses awk
and has the following advantages:
;
Formatted version:
awk -F '=' '/^\s*database_version\s*=/ {
sub(/^ +/, "", $2);
sub(/ +$/, "", $2);
print $2;
exit;
}' parameters.ini
One-liner:
awk -F '=' '/^\s*database_version\s*=/ { sub(/^ +/, "", $2); sub(/ +$/, "", $2); print $2; exit; }' parameters.ini
Note also that "key" does not necessarily mean primary key. Something like this will work:
CREATE TABLE book (
isbn BIGINT NOT NULL PRIMARY KEY,
id INT NOT NULL AUTO_INCREMENT,
accepted_terms BIT(1) NOT NULL,
accepted_privacy BIT(1) NOT NULL,
INDEX(id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
This is a contrived example and probably not the best idea, but it can be very useful in certain cases.
public static void main(String[] args) {

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();

System.out.println("File saved!");
} catch (ParserConfigurationException pce) {
pce.printStackTrace();

The values in you XML is Hard coded.
I think much confusion is generated by not communicating what is meant by passed by reference. When some people say pass by reference they usually mean not the argument itself, but rather the object being referenced. Some other say that pass by reference means that the object can't be changed in the callee. Example:
struct Object {
int i;
};
void sample(Object* o) { // 1
o->i++;
}
void sample(Object const& o) { // 2
// nothing useful here :)
}
void sample(Object & o) { // 3
o.i++;
}
void sample1(Object o) { // 4
o.i++;
}
int main() {
Object obj = { 10 };
Object const obj_c = { 10 };
sample(&obj); // calls 1
sample(obj) // calls 3
sample(obj_c); // calls 2
sample1(obj); // calls 4
}
Some people would claim that 1 and 3 are pass by reference, while 2 would be pass by value. Another group of people say all but the last is pass by reference, because the object itself is not copied.
I would like to draw a definition of that here what i claim to be pass by reference. A general overview over it can be found here: Difference between pass by reference and pass by value. The first and last are pass by value, and the middle two are pass by reference:
sample(&obj);
// yields a `Object*`. Passes a *pointer* to the object by value.
// The caller can change the pointer (the parameter), but that
// won't change the temporary pointer created on the call side (the argument).
sample(obj)
// passes the object by *reference*. It denotes the object itself. The callee
// has got a reference parameter.
sample(obj_c);
// also passes *by reference*. the reference parameter references the
// same object like the argument expression.
sample1(obj);
// pass by value. The parameter object denotes a different object than the
// one passed in.
I vote for the following definition:
An argument (1.3.1) is passed by reference if and only if the corresponding parameter of the function that's called has reference type and the reference parameter binds directly to the argument expression (8.5.3/4). In all other cases, we have to do with pass by value.
That means that the following is pass by value:
void f1(Object const& o);
f1(Object()); // 1
void f2(int const& i);
f2(42); // 2
void f3(Object o);
f3(Object()); // 3
Object o1; f3(o1); // 4
void f4(Object *o);
Object o1; f4(&o1); // 5
1
is pass by value, because it's not directly bound. The implementation may copy the temporary and then bind that temporary to the reference. 2
is pass by value, because the implementation initializes a temporary of the literal and then binds to the reference. 3
is pass by value, because the parameter has not reference type. 4
is pass by value for the same reason. 5
is pass by value because the parameter has not got reference type. The following cases are pass by reference (by the rules of 8.5.3/4 and others):
void f1(Object *& op);
Object a; Object *op1 = &a; f1(op1); // 1
void f2(Object const& op);
Object b; f2(b); // 2
struct A { };
struct B { operator A&() { static A a; return a; } };
void f3(A &);
B b; f3(b); // passes the static a by reference
Here is a way to get an InputStream
for a file in the assets
folder without a Context
, Activity
, Fragment
or Application
. How you get the data from that InputStream
is up to you. There are plenty of suggestions for that in other answers here.
Kotlin
val inputStream = ClassLoader::class.java.classLoader?.getResourceAsStream("assets/your_file.ext")
Java
InputStream inputStream = ClassLoader.class.getClassLoader().getResourceAsStream("assets/your_file.ext");
All bets are off if a custom ClassLoader
is in play.

The data you are encoding is a keyless array, so JSON encodes it with [] brackets. See www.json.org for more information about that. The curly braces are used for lists with key/value pairs.
From www.json.org:
JSON is built on two structures:
A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.
An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma).
An array is an ordered collection of values. An array begins with [ (left bracket) and ends with ] (right bracket). Values are separated by , (comma).
You need to implement the equals() method in your MyClass
.
The reason that ==
didn't work is this is checking that they refer to the same instance. Since you did new
for each, each one is a different instance.
The reason that equals()
didn't work is because you didn't implement it yourself yet. I believe it's default behavior is the same thing as ==
.
Note that you should also implement hashcode()
if you're going to implement equals()
because a lot of java.util Collections expect that.
I'd like to propose
np.min(np.append(np.where(aa>5)[0],np.inf))
This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where
returns an empty array).
Here's what I've been doing to cope with the situation.
I use global imports on a new test class.
import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;
When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:
import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;
This allows you to code away without getting 'stuck' trying to find the correct package to import.
Try this to switch to php4:
AddHandler application/x-httpd-php4 .php
Upd. Looks like I didn't understand your question correctly. This will not help if you have only php 4 on your server.
In most cases, when you find yourself using forEach
on a Stream, you should rethink whether you are using the right tool for your job or whether you are using it the right way.
Generally, you should look for an appropriate terminal operation doing what you want to achieve or for an appropriate Collector. Now, there are Collectors for producing Map
s and List
s, but no out of-the-box collector for combining two different collectors, based on a predicate.
Now, this answer contains a collector for combining two collectors. Using this collector, you can achieve the task as
Pair<Map<KeyType, Animal>, List<KeyType>> pair = animalMap.entrySet().stream()
.collect(conditional(entry -> entry.getValue() != null,
Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue),
Collectors.mapping(Map.Entry::getKey, Collectors.toList()) ));
Map<KeyType,Animal> myMap = pair.a;
List<KeyType> myList = pair.b;
But maybe, you can solve this specific task in a simpler way. One of you results matches the input type; it’s the same map just stripped off the entries which map to null
. If your original map is mutable and you don’t need it afterwards, you can just collect the list and remove these keys from the original map as they are mutually exclusive:
List<KeyType> myList=animalMap.entrySet().stream()
.filter(pair -> pair.getValue() == null)
.map(Map.Entry::getKey)
.collect(Collectors.toList());
animalMap.keySet().removeAll(myList);
Note that you can remove mappings to null
even without having the list of the other keys:
animalMap.values().removeIf(Objects::isNull);
or
animalMap.values().removeAll(Collections.singleton(null));
If you can’t (or don’t want to) modify the original map, there is still a solution without a custom collector. As hinted in Alexis C.’s answer, partitioningBy
is going into the right direction, but you may simplify it:
Map<Boolean,Map<KeyType,Animal>> tmp = animalMap.entrySet().stream()
.collect(Collectors.partitioningBy(pair -> pair.getValue() != null,
Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue)));
Map<KeyType,Animal> myMap = tmp.get(true);
List<KeyType> myList = new ArrayList<>(tmp.get(false).keySet());
The bottom line is, don’t forget about ordinary Collection operations, you don’t have to do everything with the new Stream API.
One way,
Solution Explorer > Your Project > Properties > Settings.Settings. Click on this file and add define your settings from the IDE.
Access them by
Properties.Settings.Default.MySetting = "hello world";
FYI this kind of code works (you can find it ugly, it is your right :) ) :
def list = null
list.each { println it }
soSomething()
In other words, this code has null/empty checks both useless:
if (members && !members.empty) {
members.each { doAnotherThing it }
}
def doAnotherThing(def member) {
// Some work
}
This is an example of using sleep
with sidekiq
require 'sidekiq'
class PlainOldRuby
include Sidekiq::Worker
def perform(how_hard="super hard", how_long=10)
sleep how_long
puts "Workin' #{how_hard}"
end
end
sleep for 10 seconds and print out "Working super hard"
.

Okay, as all posts say, if you want to make it search engine-friendly then bots can scrape for sure.
But you can still do a few things, and it may be affective for 60-70 % scraping bots.
Make a checker script like below.
If a particular IP address is visiting very fast then after a few visits (5-10) put its IP address + browser information in a file or database.
(This would be a background process and running all time or scheduled after a few minutes.) Make one another script that will keep on checking those suspicious IP addresses.
Case 1. If the user Agent is of a known search engine like Google, Bing, Yahoo (you can find more information on user agents by googling it). Then you must see http://www.iplists.com/. This list and try to match patterns. And if it seems like a faked user-agent then ask to fill in a CAPTCHA on the next visit. (You need to research a bit more on bots IP addresses. I know this is achievable and also try whois of the IP address. It can be helpful.)
Case 2. No user agent of a search bot: Simply ask to fill in a CAPTCHA on the next visit.
That's called a closure. It basically seals the code inside the function so that other libraries don't interfere with it. It's similar to creating a namespace in compiled languages.
Example. Suppose I write:
(function() {
var x = 2;
// do stuff with x
})();
Now other libraries cannot access the variable x
I created to use in my library.
var array = [];
//length array now = 0
array[array.length] = 'hello';
//length array now = 1
// 0
//array = ['hello'];//length = 1
If performance is important, and the list usually already is sorted quite well.
Bubble sort should be one of the slowest ways of sorting, but I have seen cases where the best performance was a simple bi-directional bubble sort.
So this may be one of the few cases where you can benefit from coding it yourself. But you really need to do it right (make sure at least somebody else confirms your code, make a proof that it works etc.)
As somebody else pointed out, it may be even better to start with a sorted array, and keep it sorted while you change the contents. That may perform even better.
This is how I handle this case:
On the machine where I have access to Internet:
mkdir keystone-deps
pip download python-keystoneclient -d "/home/aviuser/keystone-deps"
tar cvfz keystone-deps.tgz keystone-deps
Then move the tar file to the destination machine that does not have Internet access and perform the following:
tar xvfz keystone-deps.tgz
cd keystone-deps
pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index
You may need to add --no-deps to the command as follows:
pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index --no-deps
There are few named constructors in GridView

If you want your GridView items to be dynamic according to the content, you can few lines to do that but the simplest way to use StaggeredGridView
package. I have provided an answer with example here.
Below is an example for a GridView.count
:
import 'package:flutter/material.dart';
void main() => runApp(
MaterialApp(
home: ExampleGrid(),
),
);
class ExampleGrid extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: GridView.count(
crossAxisCount: 4,
children: List.generate(40, (index) {
return Card(
child: Image.network("https://robohash.org/$index"),
); //robohash.org api provide you different images for any number you are giving
}),
),
);
}
}
Screenshot for above snippet:
Example for a SliverGridView
:
import 'package:flutter/material.dart';
void main() => runApp(
MaterialApp(
home: ExampleGrid(),
),
);
class ExampleGrid extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: CustomScrollView(
primary: false,
slivers: <Widget>[
SliverPadding(
padding: const EdgeInsets.all(20.0),
sliver: SliverGrid.count(
crossAxisSpacing: 10.0,
crossAxisCount: 2,
children: List.generate(20, (index) {
return Card(child: Image.network("https://robohash.org/$index"));
}),
),
),
],
)
);
}
}
The result of Modulo operation depends on the sign of numerator, and thus you're getting -2 for y and z
Here's the reference
http://www.chemie.fu-berlin.de/chemnet/use/info/libc/libc_14.html
Integer Division
This section describes functions for performing integer division. These functions are redundant in the GNU C library, since in GNU C the '/' operator always rounds towards zero. But in other C implementations, '/' may round differently with negative arguments. div and ldiv are useful because they specify how to round the quotient: towards zero. The remainder has the same sign as the numerator.
I also had issues with this part of the tutorial (used tutorial for version 1.7).
My mistake was that I only edited the 'Django administration' string, and did not pay enough attention to the manual.
This is the line from django/contrib/admin/templates/admin/base_site.html:
<h1 id="site-name"><a href="{% url 'admin:index' %}">{{ site_header|default:_('Django administration') }}</a></h1>
But after some time and frustration it became clear that there was the 'site_header or default:_' statement, which should be removed. So after removing the statement (like the example in the manual everything worked like expected).
Example manual:
<h1 id="site-name"><a href="{% url 'admin:index' %}">Polls Administration</a></h1>
Adding the following to my .bash_profile worked for me:

WARNING: Necromancing
Still Darin Dimitrov's answer + System.Security.SecurityElement.Escape(string s) isn't complete.
In XML 1.1, the simplest and safest way is to just encode EVERYTHING.
Like 	
for \t.
It isn't supported at all in XML 1.0.
For XML 1.0, one possible workaround is to base-64 encode the text containing the character(s).
//string EncodedXml = SpecialXmlEscape("?????? ???");
//Console.WriteLine(EncodedXml);
//string DecodedXml = XmlUnescape(EncodedXml);
//Console.WriteLine(DecodedXml);
public static string SpecialXmlEscape(string input)
{
//string content = System.Xml.XmlConvert.EncodeName("\t");
//string content = System.Security.SecurityElement.Escape("\t");
//string strDelimiter = System.Web.HttpUtility.HtmlEncode("\t"); // XmlEscape("\t"); //XmlDecode("	");
//strDelimiter = XmlUnescape(";");
//Console.WriteLine(strDelimiter);
//Console.WriteLine(string.Format("&#{0};", (int)';'));
//Console.WriteLine(System.Text.Encoding.ASCII.HeaderName);
//Console.WriteLine(System.Text.Encoding.UTF8.HeaderName);
string strXmlText = "";
if (string.IsNullOrEmpty(input))
return input;
System.Text.StringBuilder sb = new StringBuilder();
for (int i = 0; i < input.Length; ++i)
{
sb.AppendFormat("&#{0};", (int)input[i]);
}
strXmlText = sb.ToString();
sb.Clear();
sb = null;
return strXmlText;
} // End Function SpecialXmlEscape
XML 1.0:
public static string Base64Encode(string plainText)
{
var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
return System.Convert.ToBase64String(plainTextBytes);
}
public static string Base64Decode(string base64EncodedData)
{
var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
Check whether title has any value or not. If not, then retrive the value using Id.
<form>
Title : <input type="text" id="title" size="40" name="title" value = ''/>
<input type="button" onclick="headingSearch(this.form)" value="Submit"/><br /><br />
</form>
<script type="text/javascript">
function headingSearch(f)
{
var title=jQuery('#title').val();
$.ajax({
type: "POST",
url: "edit.php",
data: {title:title} ,
success: function(data) {
$('.center').html(data);
}
});
}
</script>
Try this code.
In php code, use echo instead of return. Only then, javascript data will have its value.
https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/
Keep icon corners square. The system applies a mask that rounds icon corners automatically.
Keep the background simple and avoid transparency. Make sure your icon is opaque, and don’t clutter the background. Give it a simple background so it doesn’t overpower other app icons nearby. You don’t need to fill the entire icon with content.
I usually use this workaround:
try:
from .mymodule import myclass
except Exception: #ImportError
from mymodule import myclass
Which means your IDE should pick up the right code location and the python interpreter will manage to run your code.
See the locale module.
This does currency (and date) formatting.
>>> import locale
>>> locale.setlocale( locale.LC_ALL, '' )
'English_United States.1252'
>>> locale.currency( 188518982.18 )
'$188518982.18'
>>> locale.currency( 188518982.18, grouping=True )
'$188,518,982.18'
As other noted you have several options. If you want only mathematical functions. You can import only Darwin.
import Darwin
If you want mathematical functions and other standard classes and functions. You can import Foundation.
import Foundation
If you want everything and also classes for user interface, it depends if your playground is for OS X or iOS.
For OS X, you need import Cocoa.
import Cocoa
For iOS, you need import UIKit.
import UIKit
You can easily discover your playground platform by opening File Inspector (??1).
Swift version:
myLabel.layer.borderWidth = 0.5
myLabel.layer.borderColor = UIColor.greenColor().CGColor
For Swift 3:
myLabel.layer.borderWidth = 0.5
myLabel.layer.borderColor = UIColor.green.cgColor
@Jason S:
You can use slice! You just have to make sure you know how to use it. Positive #s are relative to the beginning, negative numbers are relative to the end.
js>"12345.00".slice(0,-1) 12345.0
Sorry for my graphomany but post was tagged 'jquery' earlier. So, you can't use slice() inside jQuery because slice() is jQuery method for operations with DOM elements, not substrings ... In other words answer @Jon Erickson suggest really perfect solution.
However, your method will works out of jQuery function, inside simple Javascript. Need to say due to last discussion in comments, that jQuery is very much more often renewable extension of JS than his own parent most known ECMAScript.
Here also exist two methods:
as our:
string.substring(from,to)
as plus if 'to' index nulled returns the rest of string. so:
string.substring(from)
positive or negative ...
and some other - substr() - which provide range of substring and 'length' can be positive only:
string.substr(start,length)
Also some maintainers suggest that last method string.substr(start,length)
do not works or work with error for MSIE.
I think the following class code will help you. It supports multithreading but you can do some improvement like remove sync block and and sync to getRandomId() method.
public class RandomNumberGenerator {
private static final Set<String> generatedNumbers = new HashSet<String>();
public RandomNumberGenerator() {
}
public static void main(String[] args) {
final int maxLength = 7;
final int maxTry = 10;
for (int i = 0; i < 10; i++) {
System.out.println(i + ". studentId=" + RandomNumberGenerator.getRandomId(maxLength, maxTry));
}
}
public static String getRandomId(final int maxLength, final int maxTry) {
final Random random = new Random(System.nanoTime());
final int max = (int) Math.pow(10, maxLength);
final int maxMin = (int) Math.pow(10, maxLength-1);
int i = 0;
boolean unique = false;
int randomId = -1;
while (i < maxTry) {

If your input rows are lists rather than dictionaries, then the following is a simple solution:
import pandas as pd
list_of_lists = []
list_of_lists.append([1,2,3])
list_of_lists.append([4,5,6])
pd.DataFrame(list_of_lists, columns=['A', 'B', 'C'])
# A B C
# 0 1 2 3
# 1 4 5 6
There's some sort of bogus character at the end of that source. Try deleting the last line and adding it back.
I can't figure out exactly what's there, yet ...
edit — I think it's a zero-width space, Unicode 200B. Seems pretty weird and I can't be sure of course that it's not a Stackoverflow artifact, but when I copy/paste that last function including the complete last line into the Chrome console, I get your error.
A notorious source of such characters are websites like jsfiddle. I'm not saying that there's anything wrong with them — it's just a side-effect of something, maybe the use of content-editable input widgets.
If you suspect you've got a case of this ailment, and you're on MacOS or Linux/Unix, the od
command line tool can show you (albeit in a fairly ugly way) the numeric values in the characters of the source code file. Some IDEs and editors can show "funny" characters as well. Note that such characters aren't always a problem. It's perfectly OK (in most reasonable programming languages, anyway) for there to be embedded Unicode characters in string constants, for example. The problems start happening when the language parser encounters the characters when it doesn't expect them.
Typically, your help output should include:
[options]
to indicate where the options goarg_name
for a required, singular arg[arg_name]
for an optional, singular argarg_name...
for a required arg of which there can be many (this is rare)[arg_name...]
for an arg for which any number can be suppliedarg_name
should be a descriptive, short name, in lower, snake case-l
) or a long form (e.g. --list
), include them together on the same line, as their descriptions will be the sameGREP_OPTS
Note further that it's good form to accept both -h
and --help
to trigger this message and that you should show this message if the user messes up the command-line syntax, e.g. omits a required argument.
Follow these steps:
git stash save
git checkout branch
git stash pop
I have been toying with this as well. I initially had it in my documents folder, but decided that didn't make 'philosophical' sense. I decided to create an Android directory in my home folder and place Eclipse and the Android SKK in there.
