My solution is as follows:
I didn't find a root folder under C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
.
Google told me that it might be a permission issue against current user, then I found I have a current Identity: IIS APPPOOL
in the malfunctioning server where the rest of the server has Current Identity: NT AUTHORITY\NETWORK SERVICE
.
Then I changed Current Identity from IIS APPPOOL
to NT AUTHORITY\NETWORK SERVICE
.
From here, I found that resetting the web app rebuilds the temporary ASP.NET cache, solving the issue.
I'm a day late and a dollar short on this one. If you want to view the folder structure of the GAC in Windows Explorer, you can do this by using the registry:
For a temporary view, you can substitute a drive for the folder path, which strips away the special directory properties.
As for why you'd want to do something like this, I've used this trick to compare GAC'd DLLs between different machines to make sure they're truly the same.
I deleted all DLLs from the branch which wasn't working, then I copied all DDls from my branch which was working to my branch wich wasn't. This solved the issue.
Product Version
may be preferred if you're using versioning via GitVersion or other versioning software.
To get this from within your class library you can call System.Diagnostics.FileVersionInfo.ProductVersion
:
using System.Diagnostics;
using System.Reflection;
//...
var assemblyLocation = Assembly.GetExecutingAssembly().Location;
var productVersion = FileVersionInfo.GetVersionInfo(assemblyLocation).ProductVersion
I Don't know why, but in my case, even if I remove bin folder from project, when I build project it copies old version of newtonsoft.json, I copied new version's dll from packages folder and It solves for now.
... Could not load file or assembly 'X' or one of its dependencies ...
Most likely it fails to load another dependency.
you could try to check the dependencies with a dependency walker.
I.e: https://www.dependencywalker.com/
Also check your build configuration (x86 / 64)
Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.
See here: Detected DLLs that are from the internet and "blocked" by CASPOL
As @CRice said you can use the below method to get a list of dependent assembly with publicKeyToken
public static int DependencyInfo(string args)
{
Console.WriteLine(Assembly.LoadFile(args).FullName);
Console.WriteLine(Assembly.LoadFile(args).GetCustomAttributes(typeof(System.Runtime.Versioning.TargetFrameworkAttribute), false).SingleOrDefault());
try {
var assemblies = Assembly.LoadFile(args).GetReferencedAssemblies();
if (assemblies.GetLength(0) > 0)
{
foreach (var assembly in assemblies)
{
Console.WriteLine(" - " + assembly.FullName + ", ProcessorArchitecture=" + assembly.ProcessorArchitecture);
}
return 0;
}
}
catch(Exception e) {
Console.WriteLine("An exception occurred: {0}", e.Message);
return 1;
}
finally{}
return 1;
}
i generally use it as a LinqPad script you can call it as
DependencyInfo("@c:\MyAssembly.dll");
from the code
Below is an extension method that will allow you to write code like this:
int id = request.QueryString.GetValue<int>("id");
DateTime date = request.QueryString.GetValue<DateTime>("date");
It makes use of TypeDescriptor
to perform the conversion. Based on your needs, you could add an overload which takes a default value instead of throwing an exception:
public static T GetValue<T>(this NameValueCollection collection, string key)
{
if(collection == null)
{
throw new ArgumentNullException("collection");
}
var value = collection[key];
if(value == null)
{
throw new ArgumentOutOfRangeException("key");
}
var converter = TypeDescriptor.GetConverter(typeof(T));
if(!converter.CanConvertFrom(typeof(string)))
{
throw new ArgumentException(String.Format("Cannot convert '{0}' to {1}", value, typeof(T)));
}
return (T) converter.ConvertFrom(value);
}
You could also do this:
#!/usr/bin/perl
use strict;
use warnings;
$^I = '.bak'; # create a backup copy
while (<>) {
s/<PREF>/ABCD/g; # do the replacement
print; # print to the modified file
}
Invoke the script with by
./script.pl input_file
You will get a file named input_file
, containing your changes, and a file named input_file.bak
, which is simply a copy of the original file.
I looked at these, I was getting it sorted, and then it broke the binding, as above. Came up with this solution, though simpler than most of yours, it appears to do what I want to,,,
public static ObservableCollection<string> OrderThoseGroups( ObservableCollection<string> orderThoseGroups)
{
ObservableCollection<string> temp;
temp = new ObservableCollection<string>(orderThoseGroups.OrderBy(p => p));
orderThoseGroups.Clear();
foreach (string j in temp) orderThoseGroups.Add(j);
return orderThoseGroups;
}
This is vary useful please try it and change as required.

In light of apparent dislike for how I've attempted to answer the OP's question. The literal answer is, a promise is something shared w/ other objects, while a deferred should be kept private. Primarily, a deferred (which generally extends Promise) can resolve itself, while a promise might not be able to do so.
If you're interested in the minutiae, then examine Promises/A+.
So far as I'm aware, the overarching purpose is to improve clarity and loosen coupling through a standardized interface. See suggested reading from @jfriend00:
Rather than directly passing callbacks to functions, something which can lead to tightly coupled interfaces, using promises allows one to separate concerns for code that is synchronous or asynchronous.
Personally, I've found deferred especially useful when dealing with e.g. templates that are populated by asynchronous requests, loading scripts that have networks of dependencies, and providing user feedback to form data in a non-blocking manner.
Indeed, compare the pure callback form of doing something after loading CodeMirror in JS mode asynchronously (apologies, I've not used jQuery in a while):
/* assume getScript has signature like: function (path, callback, context)
and listens to onload && onreadystatechange */
$(function () {
getScript('path/to/CodeMirror', getJSMode);
// onreadystate is not reliable for callback args.
function getJSMode() {
getScript('path/to/CodeMirror/mode/javascript/javascript.js',
ourAwesomeScript);
};
function ourAwesomeScript() {
console.log("CodeMirror is awesome, but I'm too impatient.");
};
});
To the promises formulated version (again, apologies, I'm not up to date on jQuery):
/* Assume getScript returns a promise object */
$(function () {
$.when(
getScript('path/to/CodeMirror'),
getScript('path/to/CodeMirror/mode/javascript/javascript.js')
).then(function () {
console.log("CodeMirror is awesome, but I'm too impatient.");
});
});
Apologies for the semi-pseudo code, but I hope it makes the core idea somewhat clear. Basically, by returning a standardized promise, you can pass the promise around, thus allowing for more clear grouping.
CHAR takes up less storage space than VARCHAR if all your data values in that field are the same length. Now perhaps in 2009 a 800GB database is the same for all intents and purposes as a 810GB if you converted the VARCHARs to CHARs, but for short strings (1 or 2 characters), CHAR is still a industry "best practice" I would say.
Now if you look at the wide variety of data types most databases provide even for integers alone (bit, tiny, int, bigint), there ARE reasons to choose one over the other. Simply choosing bigint every time is actually being a bit ignorant of the purposes and uses of the field. If a field simply represents a persons age in years, a bigint is overkill. Now it's not necessarily "wrong", but it's not efficient.
But its an interesting argument, and as databases improve over time, it could be argued CHAR vs VARCHAR does get less relevant.
It can also happen when your parameters are wrong in the request. In my case I was working with a API that sent me the message
"No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 401."
when I send wrong username or password with the POST request to login.
I'm way late, but check out Quandl. They have an API for stock prices and fundamentals.
Here's an example call, using Quandl-api download in csv
example:
https://www.quandl.com/api/v1/datasets/WIKI/AAPL.csv?column=4&sort_order=asc&collapse=quarterly&trim_start=2012-01-01&trim_end=2013-12-31
They support these languages. Their source data comes from Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE and more (see here).
A bug or security vulnerability in the server (either Apache or the PHP engine), or your own PHP code, might allow an attacker to obtain access to your code.
For instance if you have a PHP script to allow people to download files, and an attacker can trick this script into download some of your PHP files, then your code can be leaked.
Since it's impossible to eliminate all bugs from the software you're using, if someone really wants to steal your code, and they have enough resources, there's a reasonable chance they'll be able to.
However, as long as you keep your server up-to-date, someone with casual interest is not able to see the PHP source unless there are some obvious security vulnerabilities in your code.
Read the Security section of the PHP manual as a starting point to keeping your code safe.
How about this one-liner:
file_length = len(open('myfile.txt','r').read().split('\n'))
Takes 0.003 sec using this method to time it on a 3900 line file
def c():
import time
s = time.time()
file_length = len(open('myfile.txt','r').read().split('\n'))
print time.time() - s
From the PHP manual:
This is only called on reading/writing inaccessible properties. Your property however is public, which means it is accessible. Changing the access modifier to protected solves the issue.
I solve it running:
chmod 400 ~/.ssh/id_rsa
I hope to help. Good luck.
sudo chown -R yourname:www-data cake
then
sudo chmod -R g+s cake
First command changes owner and group.
Second command adds s attribute which will keep new files and directories within cake having the same group permissions.
If you want to change ng-view you'll have to use the '#'
$window.location.href= "#operation";
Briefly, the error means that you can't use a static library to be linked w/ a dynamic one.
The correct way is to have a libavcodec
compiled into a .so
instead of .a
, so the other .so
library you are trying to build will link well.
The shortest way to do so is to add --enable-shared
at ./configure
options. Or even you may try to disable shared (or static) libraries at all... you choose what is suitable for you!

Actually, the standard shell is Bourne shell (sh
). /bin/sh
on Linux is actually bash
, but if you're aiming for cross-platform scripts, you're better off sticking to features of the original Bourne shell or writing it in something like perl
.
SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.
You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...
From there wizard should be self-explanatory and easy to navigate. You choose your CSV as source, desired destination, configure columns and run the package.
If you need detailed guidance, there are plenty of guides online, here is a nice one: http://www.mssqltips.com/sqlservertutorial/203/simple-way-to-import-data-into-sql-server/
That's not what map does. You really want Array.filter
. Or if you really want to remove the elements from the original list, you're going to need to do it imperatively with a for loop.
Sometimes, we are want to get the picture but not need to download it to real files,
i.e., download the data and keep it on memory.
For example, If I use the machine learning method, train a model that can recognize an image with the number (bar code).
When I spider some websites and that have those images so I can use the model to recognize it,
and I don't want to save those pictures on my disk drive,
then you can try the below method to help you keep download data on memory.

If you are using bash, you might as well write
echo -n "hello" >/dev/udp/localhost/8000
and avoid all the idiosyncrasies and incompatibilities of netcat.
This also works sending to other hosts, ex:
echo -n "hello" >/dev/udp/remotehost/8000
These are not "real" devices on the file system, but bash "special" aliases. There is additional information in the Bash Manual.
Let a
be a string and b
the string you look for. Use a.substr
to get the last n characters of a
and compare them to b (where n is the length of b
)
Or use std::equal
(include <algorithm>
)
Ex:
bool EndsWith(const string& a, const string& b) {
if (b.size() > a.size()) return false;
return std::equal(a.begin() + a.size() - b.size(), a.end(), b.begin());
}
If you want a query to use currently selected database. simply copy paste this query. (No modification required)
SELECT table_name ,
round(((data_length + index_length) / 1024 / 1024), 2) as SIZE_MB
FROM information_schema.TABLES
WHERE table_schema = DATABASE() ORDER BY SIZE_MB DESC;
answer to your question is simple order is not a object make it an array. var order = new Array(); order.push(/item to push/); when ever this error appears just check the left of which property the error is in this case it is push which is order[] so it is undefined.

Although, the question is fairly old, I'm adding info not present in other answers.
The OP is using stop() to stop the current animation as soon as the event completes. However, using the right mix of parameters with the function should help. eg. stop(true,true) or stop(true,false) as this affects the queued animations well.
The following link illustrates a demo that shows the different parameters available with stop() and how they differ from finish().
Although the OP had no issues using JqueryUI, this is for other users who may come across similar scenarios but cannot use JqueryUI/need to support IE7 and 8 too.
Using npm
Latest version while still respecting the semver in your package.json: npm update <package-name>
.
So, if your package.json says "react": "^15.0.0"
and you run npm update react
your package.json will now say "react": "^15.6.2"
(the currently latest version of react 15).
But since you want to go from react 15 to react 16, that won't do.
Latest version regardless of your semver: npm install --save react@latest
.
If you want a specific version, you run npm install --save react@<version>
e.g. npm install --save [email protected]
.

Using yarn
Latest version while still respecting the semver in your package.json: yarn upgrade react

As explained in Django docs, initial
is not default
.
The initial value of a field is intended to be displayed in an HTML . But if the user delete this value, and finally send back a blank value for this field, the initial
value is lost. So you do not obtain what is expected by a default behaviour.
The default behaviour is : the value that validation process will take if data
argument do not contain any value for the field.
To implement that, a straightforward way is to combine initial
and clean_<field>()
:
class JournalForm(ModelForm):
tank = forms.IntegerField(widget=forms.HiddenInput(), initial=123)
(...)
def clean_tank(self):
if not self['tank'].html_name in self.data:
return self.fields['tank'].initial
return self.cleaned_data['tank']
Ok, solved my problem, if anyone is passing by here is the answer:
Just had to add left: 0,
and top: 0,
to the styles, and yes, I'm tired.
position: 'absolute',
left: 0,
top: 0,
You can also do it using netrw
The explore command opens up netrw in the directory of the open file
:E
Move the cursor over the file you want to rename:
R
Type in the new name, press enter, press y.
Instead of "returning true", you can also use the "noop" or null utility (as referred in the POSIX specs) :
and just "do nothing". You'll save a few letters. :)

I don't think you can. You may need to use an Iframe instead.
Aside from getting decode
and encode
backwards, I think part of the answer here is actually don't use the ascii
encoding. It's probably not what you want.
To begin with, think of str
like you would a plain text file. It's just a bunch of bytes with no encoding actually attached to it. How it's interpreted is up to whatever piece of code is reading it. If you don't know what this paragraph is talking about, go read Joel's The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets right now before you go any further.
Naturally, we're all aware of the mess that created. The answer is to, at least within memory, have a standard encoding for all strings. That's where unicode
comes in. I'm having trouble tracking down exactly what encoding Python uses internally for sure, but it doesn't really matter just for this. The point is that you know it's a sequence of bytes that are interpreted a certain way. So you only need to think about the characters themselves, and not the bytes.
The problem is that in practice, you run into both. Some libraries give you a str
, and some expect a str
. Certainly that makes sense whenever you're streaming a series of bytes (such as to or from disk or over a web request). So you need to be able to translate back and forth.
Enter codecs
: it's the translation library between these two data types. You use encode
to generate a sequence of bytes (str
) from a text string (unicode
), and you use decode
to get a text string (unicode
) from a sequence of bytes (str
).
For example:
>>> s = "I look like a string, but I'm actually a sequence of bytes. \xe2\x9d\xa4"
>>> codecs.decode(s, 'utf-8')
u"I look like a string, but I'm actually a sequence of bytes. \u2764"
What happened here? I gave Python a sequence of bytes, and then I told it, "Give me the unicode
version of this, given that this sequence of bytes is in 'utf-8'
." It did as I asked, and those bytes (a heart character) are now treated as a whole, represented by their Unicode codepoint.
Let's go the other way around:
>>> u = u"I'm a string! Really! \u2764"
>>> codecs.encode(u, 'utf-8')
"I'm a string! Really! \xe2\x9d\xa4"
I gave Python a Unicode string, and I asked it to translate the string into a sequence of bytes using the 'utf-8'
encoding. So it did, and now the heart is just a bunch of bytes it can't print as ASCII; so it shows me the hexadecimal instead.
We can work with other encodings, too, of course:
>>> s = "I have a section \xa7"
>>> codecs.decode(s, 'latin1')
u'I have a section \xa7'
>>> codecs.decode(s, 'latin1')[-1] == u'\u00A7'
True
>>> u = u"I have a section \u00a7"
>>> u
u'I have a section \xa7'
>>> codecs.encode(u, 'latin1')
'I have a section \xa7'
('\xa7'
is the section character, in both
Unicode and Latin-1.)
So for your question, you first need to figure out what encoding your str
is in.
Did it come from a file? From a web request? From your database? Then the source determines the encoding. Find out the encoding of the source and use that to translate it into a unicode
.
s = [get from external source]
u = codecs.decode(s, 'utf-8') # Replace utf-8 with the actual input encoding
Or maybe you're trying to write it out somewhere. What encoding does the destination expect? Use that to translate it into a str
. UTF-8 is a good choice for plain text documents; most things can read it.
u = u'My string'
s = codecs.encode(u, 'utf-8') # Replace utf-8 with the actual output encoding
[Write s out somewhere]
Are you just translating back and forth in memory for interoperability or something? Then just pick an encoding and stick with it; 'utf-8'
is probably the best choice for that:
u = u'My string'
s = codecs.encode(u, 'utf-8')
newu = codecs.decode(s, 'utf-8')
In modern programming, you probably never want to use the 'ascii'
encoding for any of this. It's an extremely small subset of all possible characters, and no system I know of uses it by default or anything.
Python 3 does its best to make this immensely clearer simply by changing the names. In Python 3, str
was replaced with bytes
, and unicode
was replaced with str
.

As iEamin said in his answer, HTML 5 does now support this. The link he gave, http://www.html5rocks.com/en/tutorials/file/dndfiles/ , is excellent. Here is a minimal sample based on the samples at that site, but see that site for more thorough examples.
Add an onchange
event listener to your HTML:
<input type="file" onchange="onFileSelected(event)">
Make an image tag with an id (I'm specifying height=200
to make sure the image isn't too huge onscreen):
<img id="myimage" height="200">
Here is the JavaScript of the onchange
event listener. It takes the File
object that was passed as event.target.files[0]
, constructs a FileReader
to read its contents, and sets up a new event listener to assign the resulting data:
URL to the img
tag:
function onFileSelected(event) {
var selectedFile = event.target.files[0];
var reader = new FileReader();
var imgtag = document.getElementById("myimage");
imgtag.title = selectedFile.name;
reader.onload = function(event) {
imgtag.src = event.target.result;
};
reader.readAsDataURL(selectedFile);
}
$('.toggle img').each(function(index) {
if($(this).attr('data-id') == '4')
{
$(this).attr('data-block', 'something');
$(this).attr('src', 'something.jpg');
}
});
or
$('.toggle img[data-id="4"]').attr('data-block', 'something');
$('.toggle img[data-id="4"]').attr('src', 'something.jpg');
Difference Between ClassNotFoundException Vs NoClassDefFoundError
Out of the box, the == operator only works for primitives. To get your code to work, you need to overload the == operator for your struct.
Well I always use the same easy way and it works for me. In your HTML keep the type as text (like this):
<input type="text" class="textfield" value="" id="onlyNumbers" name="onlyNumbers" onkeypress="return isNumber(event)" onpaste="return false;"/>
After this you only need to add a method on javascript
<script type="text/javascript">
function isNumber(evt) {
evt = (evt) ? evt : window.event;
var charCode = (evt.which) ? evt.which : evt.keyCode;
if ( (charCode > 31 && charCode < 48) || charCode > 57) {
return false;
}
return true;
}
</script>
With this easy validation you will only get positive numbers as you wanted. You can modify the charCodes to add more valid keys to your method.
Here´s the code working: Only numbers validation

You need to make sure the standalone ChromeDriver binary (which is different than the Chrome browser binary) is either in your path or available in the webdriver.chrome.driver environment variable.

Edit:
Right, seems to be a bug in the Python bindings wrt reading the chromedriver binary from the path or the environment variable. Seems if chromedriver is not in your path you have to pass it in as an argument to the constructor.
import os
from selenium import webdriver
chromedriver = "/Users/adam/Downloads/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)
driver.get("http://stackoverflow.com")
driver.quit()
I had the same "TypeError: an integer is required" error message when attempting to write. Thanks, the .encode() solved it for me. I'm running python 3.4 on a Dell D530 running 32 bit Windows XP Pro.
I'm omitting the com port settings here:
>>>import serial
>>>ser = serial.Serial(5)
>>>ser.close()
>>>ser.open()
>>>ser.write("1".encode())
1

Note:
* This answer probably goes deeper than the use case warrants, and find 2>/dev/null
may be good enough in many situations. It may still be of interest for a cross-platform perspective and for its discussion of some advanced shell techniques in the interest of finding a solution that is as robust as possible, even though the cases guarded against may be largely hypothetical.
* If your system is configured to show localized error messages, prefix the find
calls below with LC_ALL=C
(LC_ALL=C find ...
) to ensure that English messages are reported, so that grep -v 'Permission denied'
works as intended. Invariably, however, any error messages that do get displayed will then be in English as well.
If your shell is bash
or zsh
, there's a solution that is robust while being reasonably simple, using only POSIX-compliant find
features; while bash
itself is not part of POSIX, most modern Unix platforms come with it, making this solution widely portable:
find . > files_and_folders 2> >(grep -v 'Permission denied' >&2)
Note: There's a small chance that some of grep
's output may arrive after find
completes, because the overall command doesn't wait for the command inside >(...)
to finish. In bash
, you can prevent this by appending | cat
to the command.
>(...)
is a (rarely used) output process substitution that allows redirecting output (in this case, stderr output (2>
) to the stdin of the command inside >(...)
.
In addition to bash
and zsh
, ksh
supports them as well in principle, but trying to combine them with redirection from stderr, as is done here (2> >(...)
), appears to be silently ignored (in ksh 93u+
).
grep -v 'Permission denied'
filters out (-v
) all lines (from the find
command's stderr stream) that contain the phrase Permission denied
and outputs the remaining lines to stderr (>&2
).This approach is:
robust: grep
is only applied to error messages (and not to a combination of file paths and error messages, potentially leading to false positives), and error messages other than permission-denied ones are passed through, to stderr.
side-effect free: find
's exit code is preserved: the inability to access at least one of the filesystem items encountered results in exit code 1
(although that won't tell you whether errors other than permission-denied ones occurred (too)).
Fully POSIX-compliant solutions either have limitations or require additional work.
If find
's output is to be captured in a file anyway (or suppressed altogether), then the pipeline-based solution from Jonathan Leffler's answer is simple, robust, and POSIX-compliant:
find . 2>&1 >files_and_folders | grep -v 'Permission denied' >&2
Note that the order of the redirections matters: 2>&1
must come first.
Capturing stdout output in a file up front allows 2>&1
to send only error messages through the pipeline, which grep
can then unambiguously operate on.
The only downside is that the overall exit code will be the grep
command's, not find
's, which in this case means: if there are no errors at all or only permission-denied errors, the exit code will be 1
(signaling failure), otherwise (errors other than permission-denied ones) 0
- which is the opposite of the intent.
That said, find
's exit code is rarely used anyway, as it often conveys little information beyond fundamental failure such as passing a non-existent path.
However, the specific case of even only some of the input paths being inaccessible due to lack of permissions is reflected in find
's exit code (in both GNU and BSD find
): if a permissions-denied error occurs for any of the files processed, the exit code is set to 1
.
The following variation addresses that:
find . 2>&1 >files_and_folders | { grep -v 'Permission denied' >&2; [ $? -eq 1 ]; }
Now, the exit code indicates whether any errors other than Permission denied
occurred: 1
if so, 0
otherwise.
In other words: the exit code now reflects the true intent of the command: success (0
) is reported, if no errors at all or only permission-denied errors occurred.
This is arguably even better than just passing find
's exit code through, as in the solution at the top.
gniourf_gniourf in the comments proposes a (still POSIX-compliant) generalization of this solution using sophisticated redirections, which works even with the default behavior of printing the file paths to stdout:
{ find . 3>&2 2>&1 1>&3 | grep -v 'Permission denied' >&3; } 3>&2 2>&1
In short: Custom file descriptor 3
is used to temporarily swap stdout (1
) and stderr (2
), so that error messages alone can be piped to grep
via stdout.
Without these redirections, both data (file paths) and error messages would be piped to grep
via stdout, and grep
would then not be able to distinguish between error message Permission denied
and a (hypothetical) file whose name happens to contain the phrase Permission denied
.
As in the first solution, however, the the exit code reported will be grep
's, not find
's, but the same fix as above can be applied.
There are several points to note about Michael Brux's answer, find . ! -readable -prune -o -print
:
It requires GNU find
; notably, it won't work on macOS. Of course, if you only ever need the command to work with GNU find
, this won't be a problem for you.
Some Permission denied
errors may still surface: find ! -readable -prune
reports such errors for the child items of directories for which the current user does have r
permission, but lacks x
(executable) permission. The reason is that because the directory itself is readable, -prune
is not executed, and the attempt to descend into that directory then triggers the error messages. That said, the typical case is for the r
permission to be missing.
Note: The following point is a matter of philosophy and/or specific use case, and you may decide it is not relevant to you and that the command fits your needs well, especially if simply printing the paths is all you do:
find
command, then the opposite approach of proactively preventing permission-denied errors requires introducing "noise" into the find
command, which also introduces complexity and logical pitfalls.-name
filter, as follows:find . ! -readable -prune -o -name '*.txt'
-print
action is required (an explanation can be found in this answer). Such subtleties can introduce bugs.The first solution in Jonathan Leffler's answer, find . 2>/dev/null > files_and_folders
, as he himself states, blindly silences all error messages (and the workaround is cumbersome and not fully robust, as he also explains). Pragmatically speaking, however, it is the simplest solution, as you may be content to assume that any and all errors would be permission-related.
mist's answer, sudo find . > files_and_folders
, is concise and pragmatic, but ill-advised for anything other than merely printing filenames, for security reasons: because you're running as the root user, "you risk having your whole system being messed up by a bug in find or a malicious version, or an incorrect invocation which writes something unexpectedly, which could not happen if you ran this with normal privileges" (from a comment on mist's answer by tripleee).
The 2nd solution in viraptor's answer, find . 2>&1 | grep -v 'Permission denied' > some_file
runs the risk of false positives (due to sending a mix of stdout and stderr through the pipeline), and, potentially, instead of reporting non-permission-denied errors via stderr, captures them alongside the output paths in the output file.
Just pass your regression model into the following function:
plot_coeffs <- function(mlr_model) {
coeffs <- coefficients(mlr_model)
mp <- barplot(coeffs, col="#3F97D0", xaxt='n', main="Regression Coefficients")
lablist <- names(coeffs)
text(mp, par("usr")[3], labels = lablist, srt = 45, adj = c(1.1,1.1), xpd = TRUE, cex=0.6)
}
Use as follows:
model <- lm(Petal.Width ~ ., data = iris)
plot_coeffs(model)
Generically, you can use a custom font using @font-face
in your CSS. Here's a very basic example:
@font-face {
font-family: 'YourFontName'; /*a name to be used later*/
src: url('http://domain.com/fonts/font.ttf'); /*URL to font*/
}
Then, trivially, to use the font on a specific element:
.classname {
font-family: 'YourFontName';
}
(.classname
is your selector).
Note that certain font-formats don't work on all browsers; you can use fontsquirrel.com's generator to avoid too much effort converting.
You can find a nice set of free web-fonts provided by Google Fonts (also has auto-generated CSS @font-face
rules, so you don't have to write your own).
while also preventing people from having free access to download the font, if possible
Nope, it isn't possible to style your text with a custom font embedded via CSS, while preventing people from downloading it. You need to use images, Flash, or the HTML5 Canvas, all of which aren't very practical.
I hope that helped!
There's a couple of ways to accomplish this decently efficiently.
First -
If possible, you can do some sort of bulk insert to a temporary table. This depends somewhat on your RDBMS/host language, but at worst this can be accomplished with a simple dynamic SQL (using a VALUES()
clause), and then a standard update-from-another-table. Most systems provide utilities for bulk load, though
Second -
And this is somewhat RDBMS dependent as well, you could construct a dynamic update statement. In this case, where the VALUES(...)
clause inside the CTE has been created on-the-fly:
WITH Tmp(id, px, py) AS (VALUES(id1, newsPosX1, newPosY1),
(id2, newsPosX2, newPosY2),
......................... ,
(idN, newsPosXN, newPosYN))
UPDATE TableToUpdate SET posX = (SELECT px
FROM Tmp
WHERE TableToUpdate.id = Tmp.id),
posY = (SELECT py
FROM Tmp
WHERE TableToUpdate.id = Tmp.id)
WHERE id IN (SELECT id
FROM Tmp)
(According to the documentation, this should be valid SQLite syntax, but I can't get it to work in a fiddle)
Sometimes the port which you are trying to access, gets occupied and won't be released. Try some tools to find whether the port is in use or not. I also faced the same issue. I tried giving different port numbers but unfortunately it didn't work. I tried restarting the system (not the application server), and it worked :)
As I needed to check if there are items from a list in a (long) string, I ended up with this one:
listOfStrings.Any(x => myString.ToUpper().Contains(x.ToUpper()));
Or in vb.net:
listOfStrings.Any(Function(x) myString.ToUpper().Contains(x.ToUpper()))
In Centos
sudo yum install php-xml
and restart apache
sudo service httpd restart

clearfix
should contain the floating elements but in your html you have added clearfix
only after floating right that is your pull-right
so you should do like this:
<div class="clearfix">
<div id="sidebar">
<ul>
<li>A</li>
<li>A</li>
<li>C</li>
<li>D</li>
<li>E</li>
<li>F</li>
<li>...</li>
<li>Z</li>
</ul>
</div>
<div id="main">
<div>
<div class="pull-right">
<a>RIGHT</a>
</div>
</div>
<div>MOVED BELOW Z</div>
</div>
Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden;
as you have done in your main.
How about something like the code below to tell if your app was signed with the debug key? it's not detecting the emulator but it might work for your purpose?
public void onCreate Bundle b ) {
super.onCreate(savedInstanceState);
if ( signedWithDebugKey(this,this.getClass()) ) {
blah blah blah
}
blah
blah
blah
}
static final String DEBUGKEY =
"get the debug key from logcat after calling the function below once from the emulator";
public static boolean signedWithDebugKey(Context context, Class<?> cls)
{
boolean result = false;
try {
ComponentName comp = new ComponentName(context, cls);
PackageInfo pinfo = context.getPackageManager().getPackageInfo(comp.getPackageName(),PackageManager.GET_SIGNATURES);
Signature sigs[] = pinfo.signatures;
for ( int i = 0; i < sigs.length;i++)
Log.d(TAG,sigs[i].toCharsString());
if (DEBUGKEY.equals(sigs[0].toCharsString())) {
result = true;
Log.d(TAG,"package has been signed with the debug key");
} else {
Log.d(TAG,"package signed with a key other than the debug key");
}
} catch (android.content.pm.PackageManager.NameNotFoundException e) {
return false;
}
return result;
}
Step-by-step:
1) Open the page with old NDK versions:
https://developer.android.com/ndk/downloads/older_releases
2) Agree the Terms:
3) Download the older version of NDK
(for example 16b):
4) Open your toolchains
directory.
5) Transfer files that you need from toolchains
folder of downloaded zip-file to your toolchains
folder:
6) Rebuild the Project:
UPD 30 Sep 2018:
I used Android NDK Revision r16b for fix this error in my own case. So I present the example with this version.
But it's better to use the Android NDK, Revision r17c (June 2018). It is the last one, supporting mips (reasonable reccomendation from Weekend's comment).

If you are adding integers, as you say in your question, this will add 50 (from 1 to 50):
for (int x = 1; x <= 50; x++)
{
list.Items.Add(x);
}
You do not need to set DisplayMember and ValueMember unless you are adding objects that have specific properties that you want to display to the user. In your example:
listbox1.Items.Add(new { clan = "Foo", sifOsoba = 1234 });
Well, you could call BigDecimal.intValue()
:
Converts this BigDecimal to an int. This conversion is analogous to a narrowing primitive conversion from double to short as defined in the Java Language Specification: any fractional part of this BigDecimal will be discarded, and if the resulting "BigInteger" is too big to fit in an int, only the low-order 32 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of this BigDecimal value as well as return a result with the opposite sign.
You can then either explicitly call Integer.valueOf(int)
or let auto-boxing do it for you if you're using a sufficiently recent version of Java.

Markup declarations can affect the content of the document, as passed from an XML processor to an application; examples are attribute defaults and entity declarations. The standalone document declaration, which may appear as a component of the XML declaration, signals whether or not there are such declarations which appear external to the document entity or in parameter entities. [Definition: An external markup declaration is defined as a markup declaration occurring in the external subset or in a parameter entity (external or internal, the latter being included because non-validating processors are not required to read them).]
In vim
:%s/<option value='.\{1,}' >//
or
:%s/<option value='.\+' >//
In vim regular expressions you have to escape the one-or-more symbol, capturing parentheses, the bounded number curly braces and some others.
See :help /magic
to see which special characters need to be escaped (and how to change that).
ABoolean (with a uppercase 'B') is a Boolean object, which if not assigned a value, will default to null. boolean (with a lowercase 'b') is a boolean primitive, which if not assigned a value, will default to false.
Boolean objectBoolean;
boolean primitiveBoolean;
System.out.println(objectBoolean); // will print 'null'
System.out.println(primitiveBoolean); // will print 'false'
so in your code because boolean with small 'b' is declared it will set to false hence
boolean turnedOn;
if(turnedOn) **meaning true**
{
//do stuff when the condition is false or true?
}
else
{
//do else of if ** itwill do this part bechae it is false
}
the if(turnedon) tests a value if true, you didnt assign a value for turned on making it false, making it do the else statement :)
Several problems arise in this question.
Problem #1 - css Specificity (how to override important rule).
According to specification - to override this selector your selector should be 'stronger' which mean it should be!important and have at least 1 id, 1 class and something else - according to you creating this selector is impossible(as you can't alter page content). So the only possible option is to put something into element style which (could be done with js). Note: style rule should also have !important to override.
Problem #2 - background is not a single property - it is a set of properties (see specification)
So you really need to know what are exact names of properties you want to change (in your case it would be background-image)
Problem #3 - How to remove rule already applied (to get previous value)?
Unfortunately css have no mechanism to dismiss rule which qualify for an element - only to override with "stronger" rule. So you won't be able to solve this task with just setting value to something like 'inherit' or 'default' cause value you want to see is neither inherit from parent nor default. To solve this problem you have couple of options.
1) You may already know what is the value you want to apply. For example you can find out this value based on selector used. So in this case you may know that for selector ".image-list li" you need background-image: url("http://placekitten.com/150/50"). If so - just you this script:
jQuery(".image-list li").attr('style', 'background-image: url("http://placekitten.com/150/50") !important; ');
2) If you don't know the value then you can try to alter page content in such a way, that rule you want to dismiss is no longer qualify for element, whereas rule you want to be shown - still qualify. In this case you may temporary remove id from container element. Here is the code:
jQuery("#an-element").attr('id', '');
var backgroundImage = jQuery(".image-list li").css('background-image');
jQuery("#an-element").attr('id', 'an-element');
jQuery(".image-list li").attr('style', 'background-image: ' + backgroundImage + ' !important; ');
Here is link to fiddle http://jsfiddle.net/o3jn9mzo/
3) As third solution - you may generate element which will qualify for desired selection to find out property value - something like this:
var backgroundImage = jQuery("<div class='image-list'><li></li></div>").find('li').css('background-image');
jQuery(".image-list li").attr('style', 'background-image: ' + backgroundImage + ' !important; ');
P.S.: Sorry for really late response.

Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.
However it means that if you are currently using APC to store other data (through the apc_store()
function) you will not be able to do that if you decide to use OPCache.
You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.
Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.
The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:
; Sets how much memory to use
opcache.memory_consumption=128
;Sets how much memory should be used by OPcache for storing internal strings
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8
; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000
;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60
;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1
;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1
If you use any library or code that uses code annotations you must enable save comments:
opcache.save_comments=1
If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)
The Chr
function in VB.NET converts the integer back to the character:
Dim i As Integer = Asc("x") ' Convert to ASCII integer.
Dim x As Char = Chr(i) ' Convert ASCII integer to char.
Even if your compareTo is holds transitivity in theory, sometimes subtle bugs mess things up... such as floating point arithmetic error. It happened to me. this was my code:
public int compareTo(tfidfContainer compareTfidf) {
//descending order
if (this.tfidf > compareTfidf.tfidf)
return -1;
else if (this.tfidf < compareTfidf.tfidf)
return 1;
else
return 0;
}
The transitive property clearly holds, but for some reason I was getting the IllegalArgumentException. And it turns out that due to tiny errors in floating point arithmetic, the round-off errors where causing the transitive property to break where they shouldn't! So I rewrote the code to consider really tiny differences 0, and it worked:
public int compareTo(tfidfContainer compareTfidf) {
//descending order
if ((this.tfidf - compareTfidf.tfidf) < .000000001)
return 0;
if (this.tfidf > compareTfidf.tfidf)
return -1;
else if (this.tfidf < compareTfidf.tfidf)
return 1;
return 0;
}
The major difference in those factories is when what you want to do with the factories and when you want to use it.
Sometimes, when you are doing IOC (inversion of control e.g. constructor injection), you know that you can create solid objects. As mentioned in the example above of fruits, if you are ready to create objects of fruits, you can use simple factory pattern.
But many times, you do not want to create solid objects, they will come later in the program flow. But the configuration tells you the what kind of factory you want to use at start, instead of creating objects, you can pass on factories which are derived from a common factory class to the constructor in IOC.
So, I think its also about the object lifetime and creation.
Turgut gave the right solution. Just for clarity, you need to add close after writing.
function openWin()
{
myWindow=window.open('','','width=200,height=100');
myWindow.document.write("<p>This is 'myWindow'</p>");
myWindow.document.close(); //missing code
myWindow.focus();
myWindow.print();
}
One common use is for template-typedef workaround classes like following:
template <class TObj>
class MyLibrariesSmartPointer
{
MyLibrariesSmartPointer();
public:
typedef smart_ptr<TObj> type;
};
Obviously a public non-implemented constructor would work aswell, but a private construtor raises a compile time error instead of a link time error, if anyone tries to instatiate MyLibrariesSmartPointer<SomeType>
instead of MyLibrariesSmartPointer<SomeType>::type
, which is desireable.
Although this answer is very late but might help other developer so I'm posting it here.
Answers above showing only how to set transparent background of TextView. We can achieve transparent Textview backcgorund in two way:
Second approach is better because it gives flexibility to set background with different color and then setting setting opacity to widget using android:alpha="0.2"
Example
<TextView
android:id="@+id/tv_name"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/black"
android:alpha="0.3"
android:textColor="@color/white"
android:textStyle="bold"/>
You can either have the newly inserted ID being output to the SSMS console like this:
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar()
(instead of .ExecuteNonQuery()
) to read the resulting ID
back.
Or if you need to capture the newly inserted ID
inside T-SQL (e.g. for later further processing), you need to create a table variable:
DECLARE @OutputTbl TABLE (ID INT)
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
This way, you can put multiple values into @OutputTbl
and do further processing on those. You could also use a "regular" temporary table (#temp
) or even a "real" persistent table as your "output target" here.
Create a role add this role to users, and then you can grant execute to all the routines in one shot to this role.
CREATE ROLE <abc>
GRANT EXECUTE TO <abc>

in php is not a function, it is an Array. To access data in arrays you use square braces ('[' and ']') which symbolize which index to get the data from. So by doing $_COOKIE['test']
you are basically saying: "Give me the data from the index 'test'.
Now, in your case, you have two possibilities: (1) either you want to see if it is false--by looking inside the cookie or (2) see if it is not even there.
For this, you use the isset function which basically checks if the variable is set or not.
Example
if ( isset($_COOKIE['test'] ) )
And if you want to check if the value is false and it is set you can do the following:
if ( isset($_COOKIE['test']) && $_COOKIE['test'] == "false" )
One thing that you can keep in mind is that if the first test fails, it wont even bother checking the next statement if it is AND ( &&
).
And to explain why you actually get the error "Function must be a string", look at this page. It's about basic creation of functions in PHP, what you must remember is that a function in PHP can only contain certain types of characters, where $
is not one of these. Since in PHP $
represents a variable.
A function could look like this: _myFunction _myFunction123 myFunction
and in many other patterns as well, but mixing it with characters like $ and % will not work.
Just to close this
foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
//textBox3.Text += ("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
Changes to this
foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
//textBox3.Text += ("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
textBox3.Text += string.Format("Key = {0}, Value = {1}", kvp.Key, kvp.Value);

Yes, you can store images in the database, but it's not advisable in my opinion, and it's not general practice.
A general practice is to store images in directories on the file system and store references to the images in the database. e.g. path to the image,the image name, etc.. Or alternatively, you may even store images on a content delivery network (CDN) or numerous hosts across some great expanse of physical territory, and store references to access those resources in the database.
Images can get quite large, greater than 1MB. And so storing images in a database can potentially put unnecessary load on your database and the network between your database and your web server if they're on different hosts.
I've worked at startups, mid-size companies and large technology companies with 400K+ employees. In my 13 years of professional experience, I've never seen anyone store images in a database. I say this to support the statement it is an uncommon practice.
%d
is for integers use %f
instead, it works for both float
and double
types:
double d = 1.2;
float f = 1.2f;
System.out.printf("%f %f",d,f); // prints 1.200000 1.200000

Just want to warn, be carefull using advice of "Andres Jaan Tack", if you dont want to lose your git hsitory.
Do you really need to do that programmatically?
Just considering the title: You could use a ShapeDrawable as android:background…
For example, let's define res/drawable/my_custom_background.xml
as:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="2dp"
android:topRightRadius="0dp"
android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp" />
<stroke
android:width="1dp"
android:color="@android:color/white" />
</shape>
and define android:background="@drawable/my_custom_background".
I've not tested but it should work.
Update:
I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/border"
android:padding="10dip" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
[... more TextView ...]
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
</LinearLayout>
and a res/drawable/border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="5dip"
android:color="@android:color/white" />
</shape>
Reported to work on a gingerbread device. Note that you'll need to relate android:padding
of the LinearLayout to the android:width
shape/stroke's value. Please, do not use @android:color/white
in your final application but rather a project defined color.
You could apply android:background="@drawable/border" android:padding="10dip"
to each of the LinearLayout from your provided sample.
As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…
Your problem resides clearly in the use of getBorder.set{Width,Height}(100);
. Why do you do that in an onClick method?
I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.
To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…
I got the same exception as you got. Reason for this is not having up and running smpt server in your machine(since your host is localhost). If you use windows 7 it does not have SMTP server . so you will have to download, install and configure with domain and creating accounts.I used hmailserver as smtp server installed and configure in my local machine. https://www.hmailserver.com/download
I think you should avoid camel caps. The norm is to use lower case letters. I would also avoid underscores and use dashes instead
So your URL should look like this (ignoring the design issues as you requested :-))
api.service.com/hello-world/user-id/x
<img>
is a replaced element; it has a display value of inline by default, but its default dimensions are defined by the embedded image's intrinsic values, like it were inline-block. You can set properties like border/border-radius, padding/margin, width, height, etc. on an image.
Replaced elements : They're elements whose contents are not affected by the current document's styles. The position of the replaced element can be affected using CSS, but not the contents of the replaced element itself.

I just realized that the hist
documentation is explicit about what to do when you already have an np.histogram
counts, bins = np.histogram(data)
plt.hist(bins[:-1], bins, weights=counts)
The important part here is that your counts are simply the weights. If you do it like that, you don't need the bar function anymore
In case this help out anyone else, in my case, I was using a CMK (it worked fine using the default aws/s3 key)

If you are only interested in the packages installed globally without the full TREE then:

Disabling the alert message is not a way to solve the problem. Despite the PHP core is continue to work it makes a dangerous assumptions and actions.

If the class organized as a singleton you can always use function getInstance() and then use getData()
Likse:
$classObj = MyClass::getInstance();
$classObj->getData();
If the class is not a singleton, use
$classObj = new MyClass();
$classObj->getData();
If you're using more than one argument it has to be in a tuple (note the extra parentheses):
'%s in %s' % (unicode(self.author), unicode(self.publication))
As EOL points out, the unicode()
function usually assumes ascii encoding as a default, so if you have non-ASCII characters, it's safer to explicitly pass the encoding:
'%s in %s' % (unicode(self.author,'utf-8'), unicode(self.publication('utf-8')))
And as of Python 3.0, it's preferred to use the str.format()
syntax instead:
'{0} in {1}'.format(unicode(self.author,'utf-8'),unicode(self.publication,'utf-8'))

There is no easy way to remove the "outdated" stuff from an existing workspace. Using the "clean" parameter will not really help, as many of the files you refer to are "free form data", only known to the plugins that are no longer available.
Your best bet is to optimize the re-import, where I would like to point out the following:
${old_workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings
folder from the old to the new workspace. This is surely the fastest way, but it may lead to weird behaviour, because some of your plugins may depend on these settings and on some of the mentioned "free form data" stored elsewhere. (There are even people symlinking these folders over multiple workspaces, but this really requires to use the same plugins on all workspaces.)Sun Tzu, an ancient Chinese strategist, general, and philosopher, said:
It is said that if you know your enemies and know yourself, you can win a hundred battles without a single loss. If you only know yourself, but not your opponent, you may win or may lose. If you know neither yourself nor your enemy, you will always endanger yourself.
In this case your enemy is HTML and you are either yourself or regex. You might even be Perl with irregular regex. Know HTML. Know yourself.

I had the same message in two phones:
- Sony Xperia E
- Samsung Galaxy Core 2
both Android 4.4.2, and i solved it with these two steps:

You can check your adb version by typing
adb version
2.- Once the phone is plugged in USB Debugging mode, A message appears asking you to authorize this computer for debugging. You have to mark "Always allow this computer", and click on Allow.

If your code can sensibly be written as a case statement, this is pretty decent:

Here's one way in XSLT 2
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"','''')"/> </xsl:template> </xsl:stylesheet>
Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:variable name="apos">'</xsl:variable> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"',$apos)"/> </xsl:template> </xsl:stylesheet>

<% using (Html.BeginForm("CustomerSearchResults", "Customer"))

It will submit the Data to Customer Controller and CustomerSearchResults Action.
Because of the condition in while
, the loop might never break:
while (entry != null) {
// If entry never becomes null here, loop will never break.
}
Instead of the null
check there, you can try this:
ZipEntry entry = null;
while ((entry = zip.getNextEntry()) != null) {
// Rest of your code
}
As of Go1.1 release, there is a bufio.Scanner API that can easily read lines from a file. Consider the following example from above, rewritten with Scanner:
package main
import (
"bufio"
"fmt"
"log"
"os"
)
// readLines reads a whole file into memory
// and returns a slice of its lines.
func readLines(path string) ([]string, error) {
file, err := os.Open(path)
if err != nil {
return nil, err
}
defer file.Close()
var lines []string
scanner := bufio.NewScanner(file)
for scanner.Scan() {
lines = append(lines, scanner.Text())
}
return lines, scanner.Err()
}
// writeLines writes the lines to the given file.
func writeLines(lines []string, path string) error {
file, err := os.Create(path)
if err != nil {
return err
}
defer file.Close()
w := bufio.NewWriter(file)
for _, line := range lines {
fmt.Fprintln(w, line)
}
return w.Flush()
}
func main() {
lines, err := readLines("foo.in.txt")
if err != nil {
log.Fatalf("readLines: %s", err)
}
for i, line := range lines {
fmt.Println(i, line)
}
if err := writeLines(lines, "foo.out.txt"); err != nil {
log.Fatalf("writeLines: %s", err)
}
}

This query used to fetch the last record in your table.
The content of the Manifest file in a JAR file created with version 1.0 of the Java Development Kit is the following.
Manifest-Version: 1.0
All the entries are as name-value pairs. The name of a header is separated from its value by a colon. The default manifest shows that it conforms to version 1.0 of the manifest specification. The manifest can also contain information about the other files that are packaged in the archive. Exactly what file information is recorded in the manifest will depend on the intended use for the JAR file. The default manifest file makes no assumptions about what information it should record about other files, so its single line contains data only about itself. Special-Purpose Manifest Headers
Depending on the intended role of the JAR file, the default manifest may have to be modified. If the JAR file is created only for the purpose of archival, then the MANIFEST.MF file is of no purpose. Most uses of JAR files go beyond simple archiving and compression and require special information to be in the manifest file. Summarized below are brief descriptions of the headers that are required for some special-purpose JAR-file functions
Applications Bundled as JAR Files: If an application is bundled in a JAR file, the Java Virtual Machine needs to be told what the entry point to the application is. An entry point is any class with a public static void main(String[] args) method. This information is provided in the Main-Class header, which has the general form:
Main-Class: classname
The value classname is to be replaced with the application's entry point.
Download Extensions: Download extensions are JAR files that are referenced by the manifest files of other JAR files. In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an extension for the purposes of that applet. Extensions may reference each other in the same way. Download extensions are specified in the Class-Path header field in the manifest file of an applet, application, or another extension. A Class-Path header might look like this, for example:
Class-Path: servlet.jar infobus.jar acme/beans.jar
With this header, the classes in the files servlet.jar, infobus.jar, and acme/beans.jar will serve as extensions for purposes of the applet or application. The URLs in the Class-Path header are given relative to the URL of the JAR file of the applet or application.
Package Sealing: A package within a JAR file can be optionally sealed, which means that all classes defined in that package must be archived in the same JAR file. A package might be sealed to ensure version consistency among the classes in your software or as a security measure. To seal a package, a Name header needs to be added for the package, followed by a Sealed header, similar to this:
Name: myCompany/myPackage/
Sealed: true
The Name header's value is the package's relative pathname. Note that it ends with a '/' to distinguish it from a filename. Any headers following a Name header, without any intervening blank lines, apply to the file or package specified in the Name header. In the above example, because the Sealed header occurs after the Name: myCompany/myPackage header, with no blank lines between, the Sealed header will be interpreted as applying (only) to the package myCompany/myPackage.
Package Versioning: The Package Versioning specification defines several manifest headers to hold versioning information. One set of such headers can be assigned to each package. The versioning headers should appear directly beneath the Name header for the package. This example shows all the versioning headers:
Name: java/util/
Specification-Title: "Java Utility Classes"
Specification-Version: "1.2"
Specification-Vendor: "Sun Microsystems, Inc.".
Implementation-Title: "java.util"
Implementation-Version: "build57"
Implementation-Vendor: "Sun Microsystems, Inc."
Regards to your question... counting one Field? I decided to make it a question, but I hope it helps...
Say I have the following DataFrame
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.normal(0, 1, (5, 2)), columns=["A", "B"])
You could count a single column by
df.A.count()
#or
df['A'].count()
both evaluate to 5.
The cool thing (or one of many w.r.t. pandas
) is that if you have NA
values, count takes that into consideration.
So if I did
df['A'][1::2] = np.NAN
df.count()
The result would be
A 3
B 5
Yes, you can always do this as 'IF' condition evaluates only when the condition inside it goes true. C does not have a boolean return type and thus returns a non-zero value when the condition is true while returns 0 whenever the condition in 'IF' turns out to be false. The non zero value returned by default is 1. Thus, both ways of writing the code are correct while I will always prefer the second one.
Here's my solution when working with hex integers and not hex strings:
def convert_hex_to_ascii(h):
chars_in_reverse = []
while h != 0x0:
chars_in_reverse.append(chr(h & 0xFF))
h = h >> 8
chars_in_reverse.reverse()
return ''.join(chars_in_reverse)
print convert_hex_to_ascii(0x7061756c)
GCC comes with a compiler runtime library (libgcc) which it uses for (among other things) providing a low-level OS abstraction for multithreading related functionality in the languages it supports. The most relevant example is libstdc++'s C++11 <thread>
, <mutex>
, and <future>
, which do not have a complete implementation when GCC is built with its internal Win32 threading model. MinGW-w64 provides a winpthreads (a pthreads implementation on top of the Win32 multithreading API) which GCC can then link in to enable all the fancy features.
I must stress this option does not forbid you to write any code you want (it has absolutely NO influence on what API you can call in your code). It only reflects what GCC's runtime libraries (libgcc/libstdc++/...) use for their functionality. The caveat quoted by @James has nothing to do with GCC's internal threading model, but rather with Microsoft's CRT implementation.
To summarize:
posix
: enable C++11/C11 multithreading features. Makes libgcc depend on libwinpthreads, so that even if you don't directly call pthreads API, you'll be distributing the winpthreads DLL. There's nothing wrong with distributing one more DLL with your application.win32
: No C++11 multithreading features.Neither have influence on any user code calling Win32 APIs or pthreads APIs. You can always use both.

If I uninstall the 64-bit anaconda and install the 32-bit, it works fine. I had a 64-bit version of openssl for windows installed, version 1.1.0 something. I uninstalled that and installed the latest I could find from here: https://slproweb.com/products/Win32OpenSSL.html -- there is a 64-bit version of 1.1.1 on there that worked. Now I can install packages via pip and conda successfully. Hope this helps.
Use
fmt.Println(t.Format("20060102150405"))
as Go uses following constants to format date,refer here
const (
stdLongMonth = "January"
stdMonth = "Jan"
stdNumMonth = "1"
stdZeroMonth = "01"
stdLongWeekDay = "Monday"
stdWeekDay = "Mon"
stdDay = "2"
stdUnderDay = "_2"
stdZeroDay = "02"
stdHour = "15"
stdHour12 = "3"
stdZeroHour12 = "03"
stdMinute = "4"

You can use the Java Geodesy Library for GPS, it uses the Vincenty's formulae which takes account of the earths surface curvature.
Implementation goes like this:
import org.gavaghan.geodesy.*;
...
GeodeticCalculator geoCalc = new GeodeticCalculator();
Ellipsoid reference = Ellipsoid.WGS84;
GlobalPosition pointA = new GlobalPosition(latitude, longitude, 0.0); // Point A
GlobalPosition userPos = new GlobalPosition(userLat, userLon, 0.0); // Point B
double distance = geoCalc.calculateGeodeticCurve(reference, userPos, pointA).getEllipsoidalDistance(); // Distance between Point A and Point B
The resulting distance is in meters.
Edit:
In 2.7 / 3.2 there is a new writeheader()
method. Also, John Machin's answer provides a simpler method of writing the header row.
Simple example of using the writeheader()
method now available in 2.7 / 3.2:
from collections import OrderedDict
ordered_fieldnames = OrderedDict([('field1',None),('field2',None)])
with open(outfile,'wb') as fou:
dw = csv.DictWriter(fou, delimiter='\t', fieldnames=ordered_fieldnames)
dw.writeheader()
# continue on to write data
Instantiating DictWriter requires a fieldnames argument.
From the documentation:
The fieldnames parameter identifies the order in which values in the dictionary passed to the writerow() method are written to the csvfile.
Put another way: The Fieldnames argument is required because Python dicts are inherently unordered.
Below is an example of how you'd write the header and data to a file.
Note: with
statement was added in 2.6. If using 2.5: from __future__ import with_statement
with open(infile,'rb') as fin:
dr = csv.DictReader(fin, delimiter='\t')
# dr.fieldnames contains values from first row of `f`.
with open(outfile,'wb') as fou:
dw = csv.DictWriter(fou, delimiter='\t', fieldnames=dr.fieldnames)
headers = {}
for n in dw.fieldnames:
headers[n] = n
dw.writerow(headers)
for row in dr:
dw.writerow(row)
As @FM mentions in a comment, you can condense header-writing to a one-liner, e.g.:
with open(outfile,'wb') as fou:
dw = csv.DictWriter(fou, delimiter='\t', fieldnames=dr.fieldnames)
dw.writerow(dict((fn,fn) for fn in dr.fieldnames))
for row in dr:
dw.writerow(row)
The duplicate values in any column can be deleted with a simple for loop.
Sub remove()
Dim a As Long
For a = Cells(Rows.Count, 1).End(xlUp).Row To 1 Step -1
If WorksheetFunction.CountIf(Range("A1:A" & a), Cells(a, 1)) > 1 Then Rows(a).Delete
Next
End Sub
You could try using df['column'].str.
and then use any string function. Pandas documentation includes those like split
View-Page
<h:selectOneMenu id="selectOneCB" value="#{page.selectedName}">
<f:selectItems value="#{page.names}"/>
</h:selectOneMenu>
Backing-Bean
List<SelectItem> names = new ArrayList<SelectItem>();
//-- Populate list from database
names.add(new SelectItem(valueObject,"label"));
//-- setter/getter accessor methods for list
To display particular selected record, it must be one of the values in the list.

I had the same error. The problem was in the export and import of the modules.
Example of my solution:
Controller (File: posts.js)
exports.getPosts = (req, res) => {
res.json({
posts: [
{ tittle: 'First posts' },
{ tittle: 'Second posts' },
]
});
};
Router (File: posts.js)
const express = require('express');
const { getPosts } = require('../controllers/posts');
const routerPosts = express.Router();
routerPosts.get('/', getPosts);
exports.routerPosts = routerPosts;
Main (File: app.js)
const express = require('express');
const morgan = require('morgan');
const dotenv = require('dotenv');
const { routerPosts } = require('./routes/posts');
const app = express();
const port = process.env.PORT || 3000;
dotenv.config();
// Middleware
app.use(morgan('dev'));
app.use('/', routerPosts);
app.listen(port, () => {
console.log(`A NodeJS API is listining on port: ${port}`);
});

That's the way I use it:
global.ts
export var server: string = 'http://localhost:4200/';
export var var2: number = 2;
export var var3: string = 'var3';
to use it just import like that:
import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Rx';
import * as glob from '../shared/global'; //<== HERE
@Injectable()
export class AuthService {
private AuhtorizationServer = glob.server
}

if you have a regexp with groups:
str="A 54mpl3 string w1th 7 numbers scatter3r ar0und"
re=/(\d+)[m-t]/
you can use String's scan
method to find matching groups:
str.scan re
#> [["54"], ["1"], ["3"]]
To find the matching pattern:
str.to_enum(:scan,re).map {$&}
#> ["54m", "1t", "3r"]
If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:
Dictionary<string, ArrayList> result = target.GetComponents()
.ToDictionary(x => x.Key, x => x.Value);
There's no such thing as an IEnumerable<T1, T2>
but a KeyValuePair<TKey, TValue>
is fine.
First you need to make sure if both of your files are in the same working directory. Next, you can import the whole file. For example,
import myClass
or you can import the entire class and entire functions from the file. For example,
from myClass import
Finally, you need to create an instance of the class from the original file and call the instance objects.
If you have jQuery enabled you can use an escapeXml function and not have to worry about escaping arrows or special characters.
<pre>
${fn:escapeXml('

')};

You can use JavaScript like... Just give the proper path of your json file...
<!doctype html>
<html>
<head>
<script type="text/javascript" src="abc.json"></script>
<script type="text/javascript" >
function load() {
var mydata = JSON.parse(data);
alert(mydata.length);
var div = document.getElementById('data');
for(var i = 0;i < mydata.length; i++)
{
div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
}
}
</script>
</head>
<body onload="load()">
<div id="data">
</div>
</body>
</html>
Simply getting the data and appending it to a div... Initially printing the length in alert.
Here is my Json file: abc.json
data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';
Add the following CSS;

Most of the programs that convert java applications to .exe files are just wrappers around the program, and the end user will still need the JRE installed to run it. As far as I know there aren't any converters that will make it a native executable from bytecode (There have been attempts, but if any turned out successful you would hear of them by now).
As for wrappers, the best ones i've used (as previously suggested) are:

is a vector with standardized scores.

We were able to solve a similar issue here using Oracle LISTAGG. There was a point where what we were grouping on exceeded the 4K limit but this was easily solved by having the first dataset take the first 15 items to aggregate, each of which have a 256K limit.
More info: We have projects, which have change orders, which in turn have explanations. Why the database is set up to take change text in chunks of 256K limits is not known but its one of the design constraints. So the application that feeds change explanations into the table stops at 254K and inserts, then gets the next set of text and if > 254K generates another row, etc. So we have a project to a change order, a 1:1. Then we have these as 1:n for explanations. LISTAGG concatenates all these. We have RMRKS_SN values, 1 for each remark and/or for each 254K of characters.
The largest RMRKS_SN was found to be 31, so I did the first dataset pulling SN 0 to 15, the 2nd dataset 16 to 30 and the last dataset 31 to 45 -- hey, let's plan on someone adding a LOT of explanation to some change orders!
In the SQL report, the Tablix ties to the first dataset. To get the other data, here's the expression:
=First(Fields!NON_STD_TXT.Value, "DataSet_EXPLAN") & First(Fields!NON_STD_TXT.Value, "ds_EXPLAN_SN_16_TO_30") & First(Fields!NON_STD_TXT.Value, "ds_EXPLAN_SN_31_TO_45")
For us, we have to have DB Group create functions, etc. because of security constraints. So with a bit of creativity, we didn't have to do a User Aggregate or a UDF.
If your application has some sort of SN to aggregate by, this method should work. I don't know what the equivalent TSQL is -- we're fortunate to be dealing with Oracle for this report, for which LISTAGG is a Godsend.
The code is:
SELECT
LT.C_O_NBR AS LT_CO_NUM,
RT.C_O_NBR AS RT_CO_NUM,
LT.STD_LN_ITM_NBR,
RT.NON_STD_LN_ITM_NBR,
RT.NON_STD_PRJ_NBR,
LT.STD_PRJ_NBR,
NVL(LT.PRPSL_LN_NBR, RT.PRPSL_LN_NBR) AS PRPSL_LN_NBR,
LT.STD_CO_EXPL_TXT AS STD_TXT,
LT.STD_CO_EXPLN_T,
LT.STD_CO_EXPL_SN,
RT.NON_STD_CO_EXPLN_T,
LISTAGG(RT.RMRKS_TXT_FLD, '')
WITHIN GROUP(ORDER BY RT.RMRKS_SN) AS NON_STD_TXT
FROM ...
WHERE RT.RMRKS_SN BETWEEN 0 AND 15
GROUP BY
LT.C_O_NBR,
RT.C_O_NBR,
...
And in the other 2 datasets just select the LISTAGG only for the subqueries in the FROM:
SELECT
LISTAGG(RT.RMRKS_TXT_FLD, '')
WITHIN GROUP(ORDER BY RT.RMRKS_SN) AS NON_STD_TXT
FROM ...
WHERE RT.RMRKS_SN BETWEEN 31 AND 45
...
... and so on.
where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS')
should work.
if you have CRUD (index) and you need set default sorting your controller for GridView, or ListView, or more... Example
public function actionIndex()
{
$searchModel = new NewsSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
// set default sorting
$dataProvider->sort->defaultOrder = ['id' => SORT_DESC];
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
you need add
$dataProvider->sort->defaultOrder = ['id' => SORT_DESC];
If you deal with .xlsm
file instead of .xls
you can use the old method. I was trying to modify vbaProject.bin
in .xlsm
several times using DBP->DBx
method by it didn't work, also changing value of DBP
didn't. So I was very suprised that following worked :
1. Save .xlsm
as .xls
.
2. Use DBP->DBx
method on .xls
.
3. Unfortunately some erros may occur when using modified .xls
file, I had to save .xls
as .xlsx
and add modules, then save as .xlsm
.
1) Update Devise so that it can handle Rails 4.0 by adding this line to your application's Gemfile:
gem 'devise', '3.0.0.rc'
Then execute:
$ bundle
2) Add the old functionality of attr_accessible
again to rails 4.0
Try to use attr_accessible
and don't comment this out.
Add this line to your application's Gemfile:
gem 'protected_attributes'
Then execute:
$ bundle
How about below:
FileReader fileReader = new FileReader(new File("test.txt"));
BufferedReader br = new BufferedReader(fileReader);
String line = null;
// if no more lines the readLine() returns null
while ((line = br.readLine()) != null) {
// reading lines until the end of the file
}

You could define a message to throw when a certain error occurs:
throw std::invalid_argument( "received negative value" );
or you could define it like this:
std::runtime_error greatScott("Great Scott!");
double getEnergySync(int year) {
if (year == 1955 || year == 1885) throw greatScott;
return 1.21e9;
}
Typically, you would have a try ... catch
block like this:
try {
// do something that causes an exception
}catch (std::exception& e){ std::cerr << "exception: " << e.what() << std::endl; }
You don't need to downgrade you can:
Either disable undefined symbol diagnostics in the settings -- "intelephense.diagnostics.undefinedSymbols": false .

const data = filenames.map(async function(filename, i) {
if (filename.includes(".")) {
var storedFile = promisify(fs.readFile)(directory + `\\${filename}`, {

})
ob[filename.replace(".js", "")] = await storedFile
socket.emit("init", { data: ob })
}
return ob
})
}
emitData(directory)
} catch (err) {
console.log(err)
}
Who wants to try with generators?
Python is a pure pass-by-value language if you think about it the right way. A python variable stores the location of an object in memory. The Python variable does not store the object itself. When you pass a variable to a function, you are passing a copy of the address of the object being pointed to by the variable.
Contrasst these two functions
def foo(x):
x[0] = 5
def goo(x):
x = []
Now, when you type into the shell
>>> cow = [3,4,5]
>>> foo(cow)
>>> cow
[5,4,5]
Compare this to goo.
>>> cow = [3,4,5]
>>> goo(cow)
>>> goo
[3,4,5]
In the first case, we pass a copy the address of cow to foo and foo modified the state of the object residing there. The object gets modified.
In the second case you pass a copy of the address of cow to goo. Then goo proceeds to change that copy. Effect: none.
I call this the pink house principle. If you make a copy of your address and tell a painter to paint the house at that address pink, you will wind up with a pink house. If you give the painter a copy of your address and tell him to change it to a new address, the address of your house does not change.
The explanation eliminates a lot of confusion. Python passes the addresses variables store by value.
You have to define public String toString()
method in your Student
class. For example:
public String toString() {
return "Student: " + studentName + ", " + studentNo;
}
Broadcast receivers receive events of a certain type. I don't think you can invoke them by class name.
First, your IntentFilter must contain an event.
static final String SOME_ACTION = "com.yourcompany.yourapp.SOME_ACTION";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);
Second, when you send a broadcast, use this same action:
Intent i = new Intent(SOME_ACTION);
sendBroadcast(i);
Third, do you really need MyIntentService to be inline? Static? [EDIT] I discovered that MyIntentSerivce MUST be static if it is inline.
Fourth, is your service declared in the AndroidManifest.xml?
echo "$string" | tr xyz _
would replace each occurrence of x
, y
, or z
with _
, giving A__BC___DEF__LMN
in your example.
echo "$string" | sed -r 's/[xyz]+/_/g'
would replace repeating occurrences of x
, y
, or z
with a single _
, giving A_BC_DEF_LMN
in your example.
Quick and dirty - Turn it off:
USE_TZ = False
in your settings.py
Make
can tell you what it knows and what it will do.
Suppose you have an "install" target, which executes commands like:
cp <filelist> <destdir>/
In your generic rules, add:
uninstall :; MAKEFLAGS= ${MAKE} -j1 -spinf $(word 1,${MAKEFILE_LIST}) install \
| awk '/^cp /{dest=$NF; for (i=NF; --i>0;) {print dest"/"$i}}' \
| xargs rm -f
A similar trick can do a generic make clean
.
From man diff
, you can use -y
to do side-by-side.
-y, --side-by-side
output in two columns
Hence, say:
diff -y /tmp/test1 /tmp/test2
$ cat a $ cat b
hello hello
my name my name
is me is you
Let's compare them:
$ diff -y a b
hello hello
my name my name
is me | is you
Everybody struggles initially while installing opencv. Opencv requires lot of dependencies in back-end. The best way to start with opencv is, install it in virtual environment. I suggest you to first install python anaconda distribution and create virtual environment using it. Then inside virtual environment using conda install command you can easily install opencv. I feel this is the most safe and easy approach to install opencv. The following command work for me, you can try the same.
conda install -c menpo opencv3
This is also possible:
a {
all: unset;
}
unset: This keyword indicates to change all the properties applying to the element or the element's parent to their parent value if they are inheritable or to their initial value if not. unicode-bidi and direction values are not affected.

I realize this question is ancient and there is an accepted and an alternate answer. I also realize that my answer will only answer half of the question, but for anyone wanting to round to the nearest minute and still have a datetime compatible value using only a single function:
CAST(YourValueHere as smalldatetime);
For hours or seconds, use Jeff Ogata's answer (the accepted answer) above.
I built this little function to automatically format anything into a nice currency format.
function formatDollars($dollars)
{
return "$".number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)),2);
}
Edit
It was pointed out that this does not show negative values. I broke it into two lines so it's easier to edit the formatting. Wrap it in parenthesis if it's a negative value:
function formatDollars($dollars)
{
$formatted = "$" . number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)), 2);
return $dollars < 0 ? "({$formatted})" : "{$formatted}";
}
As I answered here, you can remove spines from all your plots through style settings (style sheet or rcParams):
import matplotlib as mpl
mpl.rcParams['axes.spines.left'] = False
mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False
mpl.rcParams['axes.spines.bottom'] = False
Rather than kludging it so you can continue, why not back up and wonder why you're running into a NaN in the first place?
If any of the numeric inputs to an operation is NaN, the output will also be NaN. That's the way the current IEEE Floating Point standard works (it's not just Javascript). That behavior is for a good reason: the underlying intention is to keep you from using a bogus result without realizing it's bogus.
The way NaN works is if something goes wrong way down in some sub-sub-sub-operation (producing a NaN at that lower level), the final result will also be NaN, which you'll immediately recognize as an error even if your error handling logic (throw/catch maybe?) isn't yet complete.
NaN as the result of an arithmetic calculation always indicates something has gone awry in the details of the arithmetic. It's a way for the computer to say "debugging needed here". Rather than finding some way to continue anyway with some number that's hardly ever right (is 0 really what you want?), why not find the problem and fix it.
A common problem in Javascript is that both parseInt(...)
and parseFloat(...)
will return NaN if given a nonsensical argument (null
, ''
, etc). Fix the issue at the lowest level possible rather than at a higher level. Then the result of the overall calculation has a good chance of making sense, and you're not substituting some magic number (0 or 1 or whatever) for the result of the entire calculation. (The trick of (parseInt(foo.value) || 0) works only for sums, not products - for products you want the default value to be 1 rather than 0, but not if the specified value really is 0.)
Perhaps for ease of coding you want a function to retrieve a value from the user, clean it up, and provide a default value if necessary, like this:
function getFoobarFromUser(elementid) {
var foobar = parseFloat(document.getElementById(elementid).innerHTML)
if (isNaN(foobar)) foobar = 3.21; // default value
return(foobar.toFixed(2));
}
-w
is the GCC-wide option to disable warning messages.
get
is a function that is called when you try to read the value player.health
, like in:
console.log(player.health);
It's effectively not much different than:
player.getHealth = function(){
return 10 + this.level*15;
}
console.log(player.getHealth());
The opposite of get is set, which would be used when you assign to the value. Since there is no setter, it seems that assigning to the player's health is not intended:
player.health = 5; // Doesn't do anything, since there is no set function defined
A very simple example:
var player = {_x000D_
level: 5_x000D_
};_x000D_

The webpack2 documentation explains this in a much cleaner way: https://webpack.js.org/guides/public-path/#use-cases
webpack has a highly useful configuration that let you specify the base path for all the assets on your application. It's called publicPath.
Set-ExecutionPolicy Unrestricted -Scope CurrentUser
This will set the execution policy for the current user (stored in HKEY_CURRENT_USER) rather than the local machine (HKEY_LOCAL_MACHINE). This is useful if you don't have administrative control over the computer.

Changing all my queries because Studio changed version isn't an option. Tried the preferences mentioned above to no effect. It didn't put the quotes in when there was a CR-LF. Perhaps it only triggers when a comma happens.
Copy-paste to Excel is a mainstay of SQL server. Mircosoft either needs a checkbox to revert back to 2008 behavior or they need to enhance the clipboard transfer to Excel such that ONE ROW EQUALS ONE ROW.
For Constants, Enum is a better choice IMHO. Here is an example
public class myClass {
public enum myEnum {
Option1("String1", 2),
Option2("String2", 2)
;
String str;
int i;
myEnum(String str1, int i1) { this.str = str1 ; this.i1 = i }
}
There's another, simpler way to do this:
npm install Node@8
(saves Node 8 as dependency in package.json)This works because node
is just a package that ships node as its package binary. It just includes as node_module/.bin which means it only makes node available to package scripts. Not main shell.

You should use parameters in your query to prevent attacks, like if someone entered '); drop table ArticlesTBL;--'
as one of the values.
string query = "INSERT INTO ArticlesTBL (ArticleTitle, ArticleContent, ArticleType, ArticleImg, ArticleBrief, ArticleDateTime, ArticleAuthor, ArticlePublished, ArticleHomeDisplay, ArticleViews)";
query += " VALUES (@ArticleTitle, @ArticleContent, @ArticleType, @ArticleImg, @ArticleBrief, @ArticleDateTime, @ArticleAuthor, @ArticlePublished, @ArticleHomeDisplay, @ArticleViews)";
SqlCommand myCommand = new SqlCommand(query, myConnection);
myCommand.Parameters.AddWithValue("@ArticleTitle", ArticleTitleTextBox.Text);
myCommand.Parameters.AddWithValue("@ArticleContent", ArticleContentTextBox.Text);
// ... other parameters
myCommand.ExecuteNonQuery();
$instance->find()
returns a reference to a variable.
You get the report when you are trying to use this reference as an argument to a function, without storing it in a variable first.
This helps preventing memory leaks and will probably become an error in the next PHP versions.
Your second code block would throw an error if it wrote like (note the &
in the function signature):
function &get_arr(){
return array(1, 2);
}
$el = array_shift(get_arr());
So a quick (and not so nice) fix would be:
$el = array_shift($tmp = $instance->find(..));
Basically, you do an assignment to a temporary variable first and send the variable as an argument.
Putting an encoded json inside the cookie is my favorite method, to get properly formated data out of a cookie. Try that:
$expiry = time() + 12345;
$data = (object) array( "value1" => "just for fun", "value2" => "i'll save whatever I want here" );
$cookieData = (object) array( "data" => $data, "expiry" => $expiry );
setcookie( "cookiename", json_encode( $cookieData ), $expiry );
then when you get your cookie next time:
$cookie = json_decode( $_COOKIE[ "cookiename" ] );
you can simply extract the expiry time, which was inserted as data inside the cookie itself..
$expiry = $cookie->expiry;
and additionally the data which will come out as a usable object :)
$data = $cookie->data;
$value1 = $cookie->data->value1;
etc. I find that to be a much neater way to use cookies, because you can nest as many small objects within other objects as you wish!
There this PHP/Java bridge. This is basically running PHP via FastCGI. I have not used it myself.
Turned out there was some extra code in the AppModel that was messing things up:
in beforeFind
and afterFind
:
App::Import("Session");
$session = new CakeSession();
$sim_id = $session->read("Simulation.id");
I don't know why, but that was what the problem was. Removing those lines fixed the issue I was having.
Make sure that your initial call to $.modal()
to apply the modal behavior is not passing in more elements than you intended. If this happens, it will end up creating a modal instance, complete with backdrop element, for EACH element in the collection. Consequently, it might look like the backdrop has been left behind, when actually you're looking at one of the duplicates.
In my case, I was attempting to create the modal content on-the-fly with some code like this:
myModal = $('<div class="modal">...lots of HTML content here...</div><!-- end modal -->');
$('body').append(myModal);
myModal.modal();
Here, the HTML comment after the closing </div>
tag meant that myModal was actually a jQuery collection of two elements - the div, and the comment. Both of them were dutifully turned into modals, each with its own backdrop element. Of course, the modal made out of the comment was invisible apart from the backdrop, so when I closed the real modal (the div) it looked like the background was left behind.
I had the same problem when I upgraded jquery UI to 1.8.1 without upgrading the corresponding theme. Only is needed to upgrade the theme too and "auto" works again.
alternative commands that does same job
tr -d ",$" < infile
awk 'gsub(",$","")' infile
This is how I do it.. I create the hash and store it using the ProtectedData
api:
public static string GenerateKeyHash(string Password)
{
if (string.IsNullOrEmpty(Password)) return null;
if (Password.Length < 1) return null;
byte[] salt = new byte[20];
byte[] key = new byte[20];
byte[] ret = new byte[40];
try
{
using (RNGCryptoServiceProvider randomBytes = new RNGCryptoServiceProvider())
{
randomBytes.GetBytes(salt);
using (var hashBytes = new Rfc2898DeriveBytes(Password, salt, 10000))
{
key = hashBytes.GetBytes(20);
Buffer.BlockCopy(salt, 0, ret, 0, 20);
Buffer.BlockCopy(key, 0, ret, 20, 20);
}
}
// returns salt/key pair
return Convert.ToBase64String(ret);
}
finally
{
if (salt != null)
Array.Clear(salt, 0, salt.Length);
if (key != null)
Array.Clear(key, 0, key.Length);
if (ret != null)
Array.Clear(ret, 0, ret.Length);
}
}
public static bool ComparePasswords(string PasswordHash, string Password)
{
if (string.IsNullOrEmpty(PasswordHash) || string.IsNullOrEmpty(Password)) return false;
if (PasswordHash.Length < 40 || Password.Length < 1) return false;
byte[] salt = new byte[20];
byte[] key = new byte[20];
byte[] hash = Convert.FromBase64String(PasswordHash);
try
{
Buffer.BlockCopy(hash, 0, salt, 0, 20);
Buffer.BlockCopy(hash, 20, key, 0, 20);
using (var hashBytes = new Rfc2898DeriveBytes(Password, salt, 10000))
{
byte[] newKey = hashBytes.GetBytes(20);
if (newKey != null)
if (newKey.SequenceEqual(key))
return true;
}
return false;
}
finally
{
if (salt != null)
Array.Clear(salt, 0, salt.Length);
if (key != null)
Array.Clear(key, 0, key.Length);
if (hash != null)
Array.Clear(hash, 0, hash.Length);
}
}
public static byte[] DecryptData(string Data, byte[] Salt)
{
if (string.IsNullOrEmpty(Data)) return null;
byte[] btData = Convert.FromBase64String(Data);
try
{
return ProtectedData.Unprotect(btData, Salt, DataProtectionScope.CurrentUser);
}
finally
{
if (btData != null)
Array.Clear(btData, 0, btData.Length);
}
}
public static string EncryptData(byte[] Data, byte[] Salt)
{
if (Data == null) return null;
if (Data.Length < 1) return null;
byte[] buffer = new byte[Data.Length];
try
{
Buffer.BlockCopy(Data, 0, buffer, 0, Data.Length);
return System.Convert.ToBase64String(ProtectedData.Protect(buffer, Salt, DataProtectionScope.CurrentUser));
}
finally
{
if (buffer != null)
Array.Clear(buffer, 0, buffer.Length);
}
}
For me gradle clean fixed it when I was having issue on Android
cd android
./gradlew clean
If you simply call interrupt()
, the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted()
is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is
Thread.currentThread().stop();
Method is deprecated, however.
Calling return
only returns from the current method. This only terminates the thread if you're at its top level.
Nevertheless, you should work with interrupt()
and build your code around it.
You can call qApp.exit();
. I always use that and never had a problem with it.
If you application is a command line application, you might indeed want to return an exit code. It's completely up to you what the code is.
The problem is your plugin. To solve this is to only enter this address:
chrome://flags/#enable-NPAPI
Click activate NPAPI, and finally restart at the bottom of the page.
A scalar always holds a single element. Whatever is in a scalar variable is always a scalar. A reference is a scalar value.
If you want to know if it is a reference, you can use ref
. If you want to know the reference type,
you can use the reftype
routine from Scalar::Util.
If you want to know if it is an object, you can use the blessed
routine from Scalar::Util. You should never care what the blessed package is, though. UNIVERSAL
has some methods to tell you about an object: if you want to check that it has the method you want to call, use can
; if you want to see that it inherits from something, use isa
; and if you want to see it the object handles a role, use DOES
.
If you want to know if that scalar is actually just acting like a scalar but tied to a class, try tied
. If you get an object, continue your checks.
If you want to know if it looks like a number, you can use looks_like_number
from Scalar::Util. If it doesn't look like a number and it's not a reference, it's a string. However, all simple values can be strings.
If you need to do something more fancy, you can use a module such as Params::Validate.
