The method join()
blocks the calling thread until the thread whose join() method is called is terminated.
The thread.get_ident()
function returns a long integer on Linux. It's not really a thread id.
I use this method to really get the thread id on Linux:
import ctypes
libc = ctypes.cdll.LoadLibrary('libc.so.6')
# System dependent, see e.g. /usr/include/x86_64-linux-gnu/asm/unistd_64.h
SYS_gettid = 186
def getThreadId():
"""Returns OS thread id - Specific to Linux"""
return libc.syscall(SYS_gettid)
Here is a POSIX version that combines many of the previous answers to deliver following features:
Here is the code and some test cases:
import threading

import os
import time

I recently had this case where I needed to append to a list continuously in one thread, loop through the items and check if the item was ready, it was an AsyncResult in my case and remove it from the list only if it was ready. I could not find any examples that demonstrated my problem clearly Here is an example demonstrating adding to list in one thread continuously and removing from the same list in another thread continuously The flawed version runs easily on smaller numbers but keep the numbers big enough and run a few times and you will see the error
The FLAWED version
import threading
import time
# Change this number as you please, bigger numbers will get the error quickly
count = 1000
l = []
def add():
for i in range(count):
l.append(i)
time.sleep(0.0001)
def remove():
for i in range(count):
l.remove(i)
time.sleep(0.0001)
t1 = threading.Thread(target=add)
t2 = threading.Thread(target=remove)
t1.start()
t2.start()
t1.join()
t2.join()
print(l)
Output when ERROR
Exception in thread Thread-63:

Conclusion
As mentioned in the earlier answers while the act of appending or popping elements from the list itself is thread safe, what is not thread safe is when you append in one thread and pop in another
import numpy as np
import threading
def threaded_process(items_chunk):
""" Your main process which runs in thread for each chunk"""
for item in items_chunk:
try:
api.my_operation(item)
except Exception:
print('error with item')
n_threads = 20
# Splitting the items into chunks equal to number of threads
array_chunk = np.array_split(input_image_list, n_threads)
thread_list = []
for thr in range(n_threads):
thread = threading.Thread(target=threaded_process, args=(array_chunk[thr]),)
thread_list.append(thread)
thread_list[thr].start()
for thread in thread_list:
thread.join()
Check this question. The correct answer has great explanation on how to terminate threads the right way: Is there any way to kill a Thread in Python?
To make the thread stop on Keyboard Interrupt signal (ctrl+c) you can catch the exception "KeyboardInterrupt" and cleanup before exiting. Like this:
try:
start_thread()
except (KeyboardInterrupt, SystemExit):
cleanup_stop_thread()
sys.exit()
This way you can control what to do whenever the program is abruptly terminated.
You can also use the built-in signal module that lets you setup signal handlers (in your specific case the SIGINT signal): http://docs.python.org/library/signal.html
Some threads do background tasks, like sending keepalive packets, or performing periodic garbage collection, or whatever. These are only useful when the main program is running, and it's okay to kill them off once the other, non-daemon, threads have exited.
Without daemon threads, you'd have to keep track of them, and tell them to exit, before your program can completely quit. By setting them as daemon threads, you can let them run and forget about them, and when your program quits, any daemon threads are killed automatically.
Most documentation and tutorials use Python's Threading
and Queue
module, and they could seem overwhelming for beginners.
Perhaps consider the concurrent.futures.ThreadPoolExecutor
module of Python 3.
Combined with with
clause and list comprehension it could be a real charm.
from concurrent.futures import ThreadPoolExecutor, as_completed
def get_url(url):
# Your actual program here. Using threading.Lock() if necessary
return ""
# List of URLs to fetch
urls = ["url1", "url2"]
with ThreadPoolExecutor(max_workers = 5) as executor:
# Create threads
futures = {executor.submit(get_url, url) for url in urls}
# as_completed() gives you the threads once finished
for f in as_completed(futures):
# Get the results
rs = f.result()
I did exactly what you're looking for in a very simple way. It is perfectly smooth in Google Chrome and Opera, and almost perfect in Firefox and Safari. Not tested in IE.
function newTab(url)
{
var tab=window.open("");
tab.document.write("<!DOCTYPE html><html>"+document.getElementsByTagName("html")[0].innerHTML+"</html>");
tab.document.close();
window.location.href=url;
}

Explanations:
Let's say there is windows A1 and B1 and websites A2 and B2.
Instead of opening B2 in B1 and then return to A1, I open B2 in A1 and re-open A2 in B1.
(Another thing that makes it work is that I don't make the user re-download A2, see line 4)
The only thing you may doesn't like is that the new tab opens before the main page.
I am not familiar with sox, but instead of making repeated calls to the program as a command line, is it possible to set it up as a service and connect to it for requests? You can take a look at the connection interface such as sqlite for inspiration.
Try this:
<?php
/*
Template Name: [contact us]
*/
get_header();
echo do_shortcode('[CONTACT-US-FORM]');
?>
All answers assume the starting array is unique. OP did not specify how to handle arrays with duplicate entries, which result in duplicate keys.
Let's look at:
a = ["item 1", "item 2", "item 3", "item 4", "item 1", "item 5"]
You will lose the item 1 => item 2
pair as it is overridden bij item 1 => item 5
:
Hash[*a]
=> {"item 1"=>"item 5", "item 3"=>"item 4"}
All of the methods, including the reduce(&:merge!)
result in the same removal.
It could be that this is exactly what you expect, though. But in other cases, you probably want to get a result with an Array
for value instead:
{"item 1"=>["item 2", "item 5"], "item 3"=>["item 4"]}
The naïve way would be to create a helper variable, a hash that has a default value, and then fill that in a loop:
result = Hash.new {|hash, k| hash[k] = [] } # Hash.new with block defines unique defaults.
a.each_slice(2) {|k,v| result[k] << v }
a
=> {"item 1"=>["item 2", "item 5"], "item 3"=>["item 4"]}
It might be possible to use assoc
and reduce
to do above in one line, but that becomes much harder to reason about and read.
A workaround (until Google fix this bug) is to use an EditText
with android:inputType="numberDecimal"
and android:digits="0123456789.,"
.
Then add a TextChangedListener to the EditText with the following afterTextChanged:
public void afterTextChanged(Editable s) {
double doubleValue = 0;
if (s != null) {
try {
doubleValue = Double.parseDouble(s.toString().replace(',', '.'));
} catch (NumberFormatException e) {
//Error
}
}
//Do something with doubleValue
}
This is straightforward if you have control over the client that is sending the communications. All you need to do is set the HttpProxy on the client-side service class.
I did this, for example, to trace a web service client running on a smartphone. I set the proxy on that client-side connection to the IP/port of Fiddler, which was running on a PC on the network. The smartphone app then sent all of its outgoing communication to the web service, through Fiddler.
This worked perfectly.
If your client is a WCF client, then see this Q&A for how to set the proxy.
Even if you don't have the ability to modify the code of the client-side app, you may be able to set the proxy administratively, depending on the webservices stack your client uses.
You aren't doing anything with the return value of replace
. You'll need to assign the result of the method, which is the new String
:
sentence = sentence.replace("and", " ");
A String
is immutable in java. Methods like replace
return a new String
.
Your contains
test is unnecessary: replace
will just no-op if there aren't instances of the text to replace.
Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json"
and format to .json
You can create a trigger which updates NoofUses
column in Coupon
table whenever
couponid
is used in CouponUse
table
query :
CREATE TRIGGER [dbo].[couponcount] ON [dbo].[couponuse]
FOR INSERT
AS
if EXISTS (SELECT 1 FROM Inserted)
BEGIN
UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)
end
I solved this on 12.10 by installing libssl-dev.
sudo apt-get install libssl-dev
In case of array like
result = [ '2015', '2014', '2013', '2011' ],
it gets tricky if you are using escape sequence like:
result = [ \'2015\', \'2014\', \'2013\', \'2011\' ].
Instead, good way to do it is to wrap the array with single quotes as follows:
result = "'"+result+"'";

Recent updates to ggplot (0.9.2+) have overhauled the syntax for themes. Most notably, opts()
is now deprecated, having been replaced by theme()
. Sandy's answer will still (as of Jan '12) generates a chart, but causes R to throw a bunch of warnings.
Here's updated code reflecting current ggplot syntax:
library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))
#base ggplot object
p <- ggplot(df, aes(x = a, y = b))
p +
#plots the points
geom_point() +
#theme with white background
theme_bw() +
#eliminates background, gridlines, and chart border
theme(
plot.background = element_blank(),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
panel.border = element_blank()
) +
#draws x and y axis line
theme(axis.line = element_line(color = 'black'))
generates:
I also ran into the same compiler error. Just a slight shorter variation of Sly_cardinal's approach.
var color: Color = Color[<string>colorId];
After some trial and error and observing the results (in other words, I hacked it), I got it to work.
Quotes ARE required to use a path name with spaces. The trick is there MUST be a space after the path names before the closing quote...like this...
robocopy "C:\Source Path " "C:\Destination Path " /option1 /option2...
This almost seems like a bug and certainly not very intuitive.

If you insert ng-click="$event.stopPropagation" on the parent element of your template, the stopPropogation will be caught as it bubbles up the tree, so you only have to write it once for your entire template.
dataGridView1.EnableHeadersVisualStyles = false;
dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;
If you want a simple program that will run with .net 4.6.1 or above on Windows, I wrote this for my own purposes after finding this question.
You simply cd to the directory above the folder you want to zip, then pass in the directory name and it will output mydir.zip. Add zipper to your path, I personally have a utils folder on C:\utils that have things like this in it.
cd C:\Users\SomeUser\Desktop\
zipper myfolder
Below is the source code and copy of the exe:
It not quite clear what exactly you are trying to do.
To reference a row in a data frame use df[row,]
To get the first position in a vector of something use match(item,vector)
, where the vector could be one of the columns of your data frame, eg df$cname
if the column name is cname.
Edit:
To combine these you would write:
df[match(item,df$cname),]
Note that the match gives you the first item in the list, so if you are not looking for a unique reference number, you may want to consider something else.
Although it's too late , But here is my experience .
Whenever you get your maven project from a source controller or just copying your project from one machine to another , you need to update the dependencies .
For this Right-click on Project on project explorer -> Maven -> Update Project.
Please consider checking the "Force update of snapshot/releases"
checkbox.
If you have not your dependencies in m2/repository then you need internet connection to get from the remote maven repository.
In case you have get from the source controller and you have not any unit test , It's probably your test folder does not include in the source controller in the first place , so you don't have those in the new repository.so you need to create those folders manually.
I have had both these cases .
After having tried some things on this page without success I had a look in the page-source and remarked that all quotes in the serialized string have been replaced by html-entities. Decoding these entities helps avoiding much headache:
$myVar = html_entity_decode($myVar);
The best solution that I've found for such case is
select column_name, data_type||
case
when data_precision is not null and nvl(data_scale,0)>0 then '('||data_precision||','||data_scale||')'
when data_precision is not null and nvl(data_scale,0)=0 then '('||data_precision||')'
when data_precision is null and data_scale is not null then '(*,'||data_scale||')'
when char_length>0 then '('||char_length|| case char_used
when 'B' then ' Byte'
when 'C' then ' Char'
else null
end||')'
end||decode(nullable, 'N', ' NOT NULL')
from user_tab_columns
where table_name = 'TABLE_NAME'
and column_name = 'COLUMN_NAME';
@Aaron Stainback, thank you for correction!
What it seems like to me is that by calling the keys method you're returning to python a dictionary object when it's looking for a list or a tuple. So try taking all of the keys in the dictionary, putting them into a list and then using the for loop.
While git clean
works well, I still find it useful to use my own script to clean the git repo, it has some advantages.
This shows a list of files to be cleaned, then interactively prompts to clean or not. This is nearly always what I want since interactively prompting per file gets tedious.
It also allows manual filtering of the list which comes in handy when there are file types you don't want to clean (and have reason not to commit).
git_clean.sh
#!/bin/bash
readarray -t -d '' FILES < <(
git ls-files -z --other --directory |
grep --null-data --null -v '.bin$\|Cargo.lock$'
)
if [ "$FILES" = "" ]; then
echo "Nothing to clean!"
exit 0
fi
echo "Dirty files:"
printf ' %s\n' "${FILES[@]}"
DO_REMOVE=0
while true; do
echo ""
read -p "Remove ${#FILES[@]} files? [y/n]: " choice
case "$choice" in
y|Y )
DO_REMOVE=1
break ;;
n|N )
echo "Exiting!"
break ;;
* ) echo "Invalid input, expected [Y/y/N/n]"
continue ;;

done
if [ "$DO_REMOVE" -eq 1 ];then

If you are using the Eloquent ORM you should consider using scopes. This would keep your logic in the model where it belongs.
So, in the model you would have:
public function scopeIdDescending($query)
{
return $query->orderBy('id','DESC');
}
And outside the model you would have:
$posts = Post::idDescending()->get();
The solution that worked for me: If you have Sqldeveloper with java incorporated, you can use the \sqldeveloper\bin\sqldeveloper.bat to launch sqldeveloper as told here.
This should work in Matlab:
set(gca, 'XAxisLocation', 'origin')
Options are: bottom, top, origin.
For Y.axis:
YAxisLocation; left, right, origin
The method I prefer assigns an array of data to the combobox. Click on the body of your userform and change the "Click" event to "Initialize". Now the combobox will fill upon the initializing of the userform. I hope this helps.
Sub UserForm_Initialize()
ComboBox1.List = Array("1001", "1002", "1003", "1004", "1005", "1006", "1007", "1008", "1009", "1010")
End Sub
This is slightly an edge case but I think it can add some value to the other answers.
If you add more details to the graph (say an annotation or a line) you'll soon discover that it is relevant when you call legend on the axis: if you call it at the bottom of the script it will capture different handles for the legend elements, messing everything.
For instance the following script:
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
ax = df.plot(kind='bar')
ax.hlines(23, -.5,.5, linestyles='dashed')
ax.annotate('average',(-0.4,23.5))
ax.legend(["AAA", "BBB"]); #quickfix: move this at the third line
Will give you this figure, which is wrong:
While this a toy example which can be easily fixed by changing the order of the commands, sometimes you'll need to modify the legend after several operations and hence the next method will give you more flexibility. Here for instance I've also changed the fontsize and position of the legend:
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
ax = df.plot(kind='bar')
ax.hlines(23, -.5,.5, linestyles='dashed')
ax.annotate('average',(-0.4,23.5))
ax.legend(["AAA", "BBB"]);
# do potentially more stuff here
h,l = ax.get_legend_handles_labels()
ax.legend(h[:2],["AAA", "BBB"], loc=3, fontsize=12)
This is what you'll get:
The pid of a backgrounded child process is stored in $!. You can store all child processes' pids into an array, e.g. PIDS[].
wait [-n] [jobspec or pid …]
Wait until the child process specified by each process ID pid or job specification jobspec exits and return the exit status of the last command waited for. If a job spec is given, all processes in the job are waited for. If no arguments are given, all currently active child processes are waited for, and the return status is zero. If the -n option is supplied, wait waits for any job to terminate and returns its exit status. If neither jobspec nor pid specifies an active child process of the shell, the return status is 127.
Use wait command you can wait for all child processes finish, meanwhile you can get exit status of each child processes via $? and store status into STATUS[]. Then you can do something depending by status.
I have tried the following 2 solutions and they run well. solution01 is more concise, while solution02 is a little complicated.
#!/bin/bash
# start 3 child processes concurrently, and store each pid into array PIDS[].
process=(a.sh b.sh c.sh)
for app in ${process[@]}; do
./${app} &
PIDS+=($!)
done
# wait for all processes to finish, and store each process's exit code into array STATUS[].
for pid in ${PIDS[@]}; do
echo "pid=${pid}"
wait ${pid}
STATUS+=($?)
done
# after all processed finish, check their exit codes in STATUS[].
i=0
for st in ${STATUS[@]}; do
if [[ ${st} -ne 0 ]]; then
echo "$i failed"
else
echo "$i finish"
fi
((i+=1))
done
#!/bin/bash
# start 3 child processes concurrently, and store each pid into array PIDS[].
i=0
process=(a.sh b.sh c.sh)
for app in ${process[@]}; do
./${app} &
pid=$!
PIDS[$i]=${pid}
((i+=1))
done
# wait for all processes to finish, and store each process's exit code into array STATUS[].
i=0
for pid in ${PIDS[@]}; do
echo "pid=${pid}"
wait ${pid}
STATUS[$i]=$?
((i+=1))
done
# after all processed finish, check their exit codes in STATUS[].
i=0
for st in ${STATUS[@]}; do
if [[ ${st} -ne 0 ]]; then
echo "$i failed"
else
echo "$i finish"
fi
((i+=1))
done

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.
main.c has a main wrapper like this:
#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
// the true main() routine.
}
spi.c, serial.c and usb.c have main wrappers for their respective test code like this:
#ifdef TEST_USB
int main(int argc, char *argv[]) {
// the main() routine for testing the usb code.
}
config.h Which is included by all the c files has an entry like this:
// Uncomment below to test the serial
//#define TEST_SERIAL
// Uncomment below to test the spi code
//#define TEST_SPI
// Uncomment below to test the usb code
#define TEST_USB
Summarized: Oracle under Windows has problems with usernames containing non-English letters or special characters:
If your machine is fresh installed, first look here. All the network related or 32 vs. 64 related issues may be not significant for you:
As others already pointed out partly, this error is highly related to the name of the TEMP dir. It occurred to me when installing Oracle 11g first time on a totally fresh Windows (e.g. Server 2008 R2 or Win 7, not important).
As I found out, on my machine the problem was, that the username contained a German special character ("ö"). Moreover Oracle cannot handle any special character, I assume, the TEMP path is limited to letters. Other colleagues here have reported problems with underscore and chinese characters.
Explanation: In Windows the TEMP dir (environment variable %TEMP%) is by default in the user directory, for example:
C:\Users\ThisUser\AppData\Local\Temp
If "ThisUser" contains special or non-ASCII characters, then in this case this affects the TEMP path, and that is where Oracle is gettings problems.
Setting the TEMP dir to different directory is of course another possibility instead of installing with another username.
Moreover, Oracle is not a fully native Windows citizen which everybody will recognize, if he opens the Oracle install logfile with notepad ;-) Obviously, this is not programmed cleanly and portable, e.g. with using "std::endl" instead of "\n" . (Yes, Notepad++ and other editors do the job.)
Overall, my impression is, if the database were of the same quality as it's installer, Oracle would not be so successful ..
Last remark: Yes, after failed install because of the special characters you see only one Oracle service named OracleRemExecService, but there is no reason to stop this manually as recommended in other solutions, if you are able to install again a fresh OS..
I've stumbled upon the same problem. Program was running great from Eclipse via "Run" button, but NOT from runnable JAR which I'd exported before. My solution was:
1) Move Main class to default package
2) Set other path for Eclipse, and other while running from the JAR file (paste this into Main.java)
public static final String sourcePath = isProgramRunnedFromJar() ? "src/" : "";
public static boolean isProgramRunnedFromJar() {
File x = getCurrentJarFileLocation();
if(x.getAbsolutePath().contains("target"+File.separator+"classes")){
return false;
} else {
return true;
}
}
public static File getCurrentJarFileLocation() {
try {
return new File(Main.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
} catch(URISyntaxException e){
e.printStackTrace();
return null;
}
}
And after that in start method you have to load files like this:
FXMLLoader loader = new FXMLLoader(getClass().getResource(sourcePath +"MainScene.fxml"));
It works for me in Eclipse Mars with e(fx)clipse plugin.
You have two ways:
First go to the particular path of Android SDK:
1) Open your command prompt and traverse to the platform-tools directory through it such as
$ cd Frameworks\Android-Sdk\platform-tools
2) Run your adb commands now such as to know that your adb is working properly :
$ adb devices OR adb logcat OR simply adb
Second way is :
1) Right click on your My Computer.
2) Open Environment variables.
3) Add new variable to your System PATH variable(Add if not exist otherwise no need to add new variable if already exist).
4) Add path of platform-tools directory to as value of this variable such as C:\Program Files\android-sdk\platform-tools.
5) Restart your computer once.
6) Now run the above adb commands such adb devices or other adb commands from anywhere in command prompt.
Also on you can fire a command on terminal setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools"
In plain JS add { passive: false }
as third argument
document.addEventListener('wheel', function(e) {
e.preventDefault();
doStuff(e);
}, { passive: false });
You can use a separate class to represent the JSON object and use @SerializedName
annotations to specify the field name to grab for each data member:
public class Response {
@SerializedName("data")
private Data data;
private static class Data {
@SerializedName("translations")
public Translation[] translations;
}
private static class Translation {
@SerializedName("translatedText")
public String translatedText;
}
public String getTranslatedText() {
return data.translations[0].translatedText;
}
}
Then you can do the parsing in your parse() method using a Gson
object:
Gson gson = new Gson();
Response response = gson.fromJson(jsonLine, Response.class);
System.out.println("Translated text: " + response.getTranslatedText());
With this approach, you can reuse the Response
class to add any other additional fields to pick up other data members you might want to extract from JSON -- in case you want to make changes to get results for, say, multiple translations in one call, or to get an additional string for the detected source language.
First, you have to create your own inline TS-Class, since the FormData Class is not well supported at the moment:
var data : {
name: string;
file: File;
} = {
name: "Name",
file: inputValue.files[0]
};
Then you send it to the Server with JSON.stringify(data)
let opts: RequestOptions = new RequestOptions();
opts.method = RequestMethods.Post;
opts.headers = headers;
this.http.post(url,JSON.stringify(data),opts);
Effort Experience Feedback here
After a lot of reading I have been using Effort in my tests: during the tests the Context is built by a factory that returns a in memory version, which lets me test against a blank slate each time. Outside of the tests, the factory is resolved to one that returns the whole Context.
However i have a feeling that testing against a full featured mock of the database tends to drag the tests down; you realize you have to take care of setting up a whole bunch of dependencies in order to test one part of the system. You also tend to drift towards organizing together tests that may not be related, just because there is only one huge object that handles everything. If you don't pay attention, you may find yourself doing integration testing instead of unit testing
I would have prefered testing against something more abstract rather than a huge DBContext but i couldn't find the sweet spot between meaningful tests and bare-bone tests. Chalk it up to my inexperience.
So i find Effort interesting; if you need to hit the ground running it is a good tool to quickly get started and get results. However i think that something a bit more elegant and abstract should be the next step and that is what I am going to investigate next. Favoriting this post to see where it goes next :)
Edit to add: Effort do take some time to warm up, so you're looking at approx. 5 seconds at test start up. This may be a problem for you if you need your test suite to be very efficient.
Edited for clarification:
I used Effort to test a webservice app. Each message M that enters is routed to a IHandlerOf<M>
via Windsor. Castle.Windsor resolves the IHandlerOf<M>
which resovles the dependencies of the component. One of these dependencies is the DataContextFactory
, which lets the handler ask for the factory
In my tests I instantiate the IHandlerOf component directly, mock all the sub-components of the SUT and handles the Effort-wrapped DataContextFactory
to the handler.
It means that I don't unit test in a strict sense, since the DB is hit by my tests. However as I said above it let me hit the ground running and I could quickly test some points in the application
A lazy way of doing this if there are alot of tables to be deleted.
Get table using the below
Copy and paste the table names from the result set and paste it after the DROP command.
I've found an issue happen to be with the Firewall. So, make sure your IP is whitelisted and the firewall does not block your connection. You can check connectivity with:
tsql -H somehost.com -p 1433
In my case, the output was:
Error 20009 (severity 9):
Unable to connect: Adaptive Server is unavailable or does not exist
OS error 111, "Connection refused"
There was a problem connecting to the server
This is an old question, but you can now write using statements without needing to block each one. They will be disposed of in reverse order when the containing block is finished.
using var responseStream = response.GetResponseStream();
using var reader = new StreamReader(responseStream);
using var writer = new StreamWriter(filename);
int chunkSize = 1024;
while (!reader.EndOfStream)
{
char[] buffer = new char[chunkSize];
int count = reader.Read(buffer, 0, chunkSize);
if (count != 0)
{
writer.Write(buffer, 0, count);
}
}

That's definitely the best way for any array whose length is a signed integral type. For arrays whose lengths are an unsigned integral type (e.g. an std::vector
in C++), then you need to modify the end condition slightly:
for(size_t i = myArray.size() - 1; i != (size_t)-1; i--)
// blah
If you just said i >= 0
, this is always true for an unsigned integer, so the loop will be an infinite loop.
I had the same problem for a long time. I solved it by running these two commands, first is to install second is to activate the env:
python3 -m pip install virtualenv
python3 -m virtualenv yourenvname
Note that I'm using python3
, you can change it to just python
if python3
fails.
Thanks.
As a heads up to others, I've oberserved that at least as manifested by TypeScript compiled by WebPack for Angular 2, you quietly get overWRITTEN instead of overLOADED methods.
myComponent {
method(): { console.info("no args"); },
method(arg): { console.info("with arg"); }
}
Calling:
myComponent.method()
seems to execute the method with arguments, silently ignoring the no-arg version, with output:
with arg
To send a file from windows to linux system
scp path-to-file user@ipaddress:/path-to-destination
Example:
scp C:/Users/adarsh/Desktop/Document.txt [email protected]:/tmp
keep in mind that there need to use forward slash(/) inplace of backward slash(\) in for the file in windows path else it will show an error
C:UsersadarshDesktopDocument.txt: No such file or directory
. After executing scp command you will ask for password of root user in linux machine. There you GO...
To send a file from linux to windows system
scp -r user@ipaddress:/path-to-file path-to-destination
Example:
scp -r [email protected]:/tmp/Document.txt C:/Users/adarsh/Desktop/
and provide your linux password. only one you have to add in this command is -r. Thanks.
For EXAMPLE
Your Path = /home/serverID_name/www/your_route_Dir/

A Soultion that WORKS:
$url = dirname(\__FILE__);
$array = explode('\\\',$url);
$count = count($array);
echo $array[$count-1];
There is a slightly better way to access attached files. You could use template reference variable to get an instance of the input element.
Here is an example based on the first answer:
@Component({
selector: 'my-app',
template: `
<div>
<input type="file" #file (change)="onChange(file.files)"/>
</div>
`,
providers: [ UploadService ]
})
export class AppComponent {
onChange(files) {
console.log(files);
}
}
Here is an example app to demonstrate this in action.
Template reference variables might be useful, e.g. you could access them via @ViewChild directly in the controller.
The layouts in /res/layout are applied to both portrait and landscape, unless you specify otherwise. Let’s assume we have /res/layout/home.xml for our homepage and we want it to look differently in the 2 layout types.
A Callback function is a method that is passed into a routine, and called at some point by the routine to which it is passed.
This is very useful for making reusable software. For example, many operating system APIs (such as the Windows API) use callbacks heavily.
For example, if you wanted to work with files in a folder - you can call an API function, with your own routine, and your routine gets run once per file in the specified folder. This allows the API to be very flexible.
The syntax for creating a new table is
CREATE TABLE new_table
AS
SELECT *
FROM old_table
This will create a new table named new_table
with whatever columns are in old_table
and copy the data over. It will not replicate the constraints on the table, it won't replicate the storage attributes, and it won't replicate any triggers defined on the table.
SELECT INTO
is used in PL/SQL when you want to fetch data from a table into a local variable in your PL/SQL block.
I also tried to work with an SQL-IN-like thing - querying against an Entity Data Model. My approach is a string builder to compose a big OR-expression. That's terribly ugly, but I'm afraid it's the only way to go right now.
Now well, that looks like this:
Queue<Guid> productIds = new Queue<Guid>(Products.Select(p => p.Key));
if(productIds.Count > 0)
{
StringBuilder sb = new StringBuilder();
sb.AppendFormat("{0}.ProductId = Guid\'{1}\'", entities.Products.Name, productIds.Dequeue());
while(productIds.Count > 0)
{
sb.AppendFormat(" OR {0}.ProductId = Guid\'{1}\'",
entities.Products.Name, productIds.Dequeue());
}
}
Working with GUIDs in this context: As you can see above, there is always the word "GUID" before the GUID ifself in the query string fragments. If you don't add this, ObjectQuery<T>.Where
throws the following exception:
The argument types 'Edm.Guid' and 'Edm.String' are incompatible for this operation., near equals expression, line 6, column 14.
Found this in MSDN Forums, might be helpful to have in mind.

... looking forward for the next version of .NET and Entity Framework, when everything get's better. :)
You state that you want to encrypt/decrypt a password. I'm not sure exactly of what your specific use case is but, generally, passwords are not stored in a form where they can be decrypted. General practice is to salt the password and use suitably powerful one-way hash (such as PBKDF2).
Take a look at the following link for more information.
Here is an easy way to fetch data from a MySQL database using PDO.
define("DB_HOST", "localhost"); // Using Constants
define("DB_USER", "YourUsername");
define("DB_PASS", "YourPassword");
define("DB_NAME", "Yourdbname");
$dbc = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME.";charset-utf8mb4", DB_USER, DB_PASS);
$print = ""; // assign an empty string
$stmt = $dbc->query("SELECT * FROM tableName"); // fetch data
$stmt->setFetchMode(PDO::FETCH_OBJ);
$print .= '<table border="1px">';
$print .= '<tr><th>First name</th>';
$print .= '<th>Last name</th></tr>';
while ($names = $stmt->fetch()) { // loop and display data
$print .= '<tr>';
$print .= "<td>{$names->firstname}</td>";
$print .= "<td>{$names->lastname}</td>";
$print .= '</tr>';
}
$print .= "</table>";
echo $print;
git reset --soft
is just for that: it is like git reset --hard
, but doesn't touch the files.
Try to get using:
var count = $("ul > li").size();
alert(count);
You can use:
width: -webkit-fit-content;
height: -webkit-fit-content;
width: -moz-fit-content;
height: -moz-fit-content;
EDIT: No. see http://red-team-design.com/horizontal-centering-using-css-fit-content-value/
Make an /login url, than accept "user" and "password" parameters via GET and don't require basic auth. Here, use php, node, java, whatever and parse your passwd file and match parameters (user/pass) against it. If there is a match then redirect to http://user:[email protected]/ (this will set credential on your browser) if not, send 401 response (without WWW-Authenticate header).
In case somebody needs to append the output and not overriding, it is possible to use "-a" or "--append" option of "tee" command :
ls 2>&1 | tee -a /tmp/ls.txt
ls 2>&1 | tee --append /tmp/ls.txt
Check you have the correct startup project selected. I had a web api project as startup. That generated this error.
Something like this?

I guess you should start with the basics from w3
https://www.w3schools.com/cssref/css3_pr_text-overflow.asp
div {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
Here's something else I found interesting. If your source is a DataTable, you can use dynamic sorting without using Dynamic Linq
DataTable orders = dataSet.Tables["SalesOrderHeader"];
EnumerableRowCollection<DataRow> query = from order in orders.AsEnumerable()
orderby order.Field<DateTime>("OrderDate")
select order;
DataView view = query.AsDataView();
bindingSource1.DataSource = view;
reference: http://msdn.microsoft.com/en-us/library/bb669083.aspx (Using DataSetExtensions)
Here is one more way to do it by converting it to a DataView:
DataTable contacts = dataSet.Tables["Contact"];
DataView view = contacts.AsDataView();
view.Sort = "LastName desc, FirstName asc";
bindingSource1.DataSource = view;
dataGridView1.AutoResizeColumns();
Typical code is to create an explicit method to add to the list, and create the ArrayList on the fly when adding. Note the synchronization so the list only gets created once!
@Override
public synchronized boolean addToList(String key, Item item) {
Collection<Item> list = theMap.get(key);
if (list == null) {
list = new ArrayList<Item>(); // or, if you prefer, some other List, a Set, etc...
theMap.put(key, list );
}
return list.add(item);
}
Bootstrap 2.3.x and later supports the dropdown-submenu

For dnf users just use dnf install *.rpm
, localinstall
is no longer needed.
you can also use vbscript
Set objFS = CreateObject("Scripting.FileSystemObject")
strFolder = "c:\test"
strDestination = "c:\tmp\"
Set objFolder = objFS.GetFolder(strFolder)
Go(objFolder)
Sub Go(objDIR)
If objDIR <> "\System Volume Information" Then
For Each eFolder in objDIR.SubFolders
Go eFolder
Next
For Each strFile In objDIR.Files
strFileName = strFile.Name
strExtension = objFS.GetExtensionName(strFile)
If strExtension = "doc" Then
objFS.CopyFile strFile , strDestination & strFileName
End If
Next
End If
End Sub
save as mycopy.vbs and on command line
c:\test> cscript /nologo mycopy.vbs
When you create a new File
, you are supposed to provide the file name, not only the directory you want to put your file in.
Try with something like
File file = new File("D:/Data/" + item.getFileName());
Do you want to adjust the images themselves, or just the way they display? If the former, you want something on the server side. If the latter, you just need to change image.height and image.width.
git rm --cached *.FileExtension
This must ignore all files from this extension
If you prefer (I need to apply this) group by two columns at same time, I just saw this point:
SELECT CONCAT (col1, '_', col2) AS Group1 ... GROUP BY Group1
Your class JSON_result
does not match your JSON string. Note how the object JSON_result
is going to represent is wrapped in another property named "Venue"
.
So either create a class for that, e.g.:
Public Class Container
Public Venue As JSON_result
End Class
Public Class JSON_result
Public ID As Integer
Public Name As String
Public NameWithTown As String
Public NameWithDestination As String
Public ListingType As String
End Class
Dim obj = JsonConvert.DeserializeObject(Of Container)(...your_json...)
or change your JSON string to
{
"ID": 3145,
"Name": "Big Venue, Clapton",
"NameWithTown": "Big Venue, Clapton, London",
"NameWithDestination": "Big Venue, Clapton, London",
"ListingType": "A",
"Address": {
"Address1": "Clapton Raod",
"Address2": "",
"Town": "Clapton",
"County": "Greater London",
"Postcode": "PO1 1ST",
"Country": "United Kingdom",
"Region": "Europe"
},
"ResponseStatus": {
"ErrorCode": "200",
"Message": "OK"
}
}
or use e.g. a ContractResolver
to parse the JSON string.
Answering the question "Undo a Git merge that hasn't been pushed yet"
You can use
git reset --hard HEAD~1
Consider the following situation where there are 2 branches master and feature-1:
$ git log --graph --oneline --all
Do Git merge
$ git merge feature-1
$ git log --graph --oneline --all
Undo Git merge
$ git reset --hard HEAD~1
$ git log --graph --oneline --all
But it would be possible if one were used in place of the variable in @html.Hidden field. As in this example.
@Html.Hidden("myVar", 0);
set the field per script:
<script>
function setMyValue(value) {
$('#myVar').val(value);
}
</script>
I hope I can at least offer no small Workaround.
Sub
don't return values and function
s don't have side effects.
Sometimes you want both side effect and return value.
This is easy to be done once you know that VBA passes arguments by default by reference so you can write your code in this way:
Sub getValue(retValue as Long)
...
retValue = 42
End SUb
Sub Main()
Dim retValue As Long
getValue retValue
...
End SUb
If you want to build DOM you can use jsdom.
There's also cheerio, it has the jQuery interface and it's a lot faster than older versions of jsdom, although these days they are similar in performance.
You might wanna have a look at htmlparser2, which is a streaming parser, and according to its benchmark, it seems to be faster than others, and no DOM by default. It can also produce a DOM, as it is also bundled with a handler that creates a DOM. This is the parser that is used by cheerio.
parse5 also looks like a good solution. It's fairly active (11 days since the last commit as of this update), WHATWG-compliant, and is used in jsdom, Angular, and Polymer.
And if you want to parse HTML for web scraping, you can use YQL1. There is a node module for it. YQL I think would be the best solution if your HTML is from a static website, since you are relying on a service, not your own code and processing power. Though note that it won't work if the page is disallowed by the robot.txt of the website, YQL won't work with it.
If the website you're trying to scrape is dynamic then you should be using a headless browser like phantomjs. Also have a look at casperjs, if you're considering phantomjs. And you can control casperjs from node with SpookyJS.
Beside phantomjs there's zombiejs. Unlike phantomjs that cannot be embedded in nodejs, zombiejs is just a node module.
There's a nettuts+ toturial for the latter solutions.
1 Since Aug. 2014, YUI library, which is a requirement for YQL, is no longer actively maintained, source
You can use from bellow code for date and time :
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
//get current date time with Calendar()
Calendar cal = Calendar.getInstance();
System.out.println("Current Date Time : " + dateFormat.format(cal.getTime()));
cal.add(Calendar.DATE, 1);
System.out.println("Add one day to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MONTH, 1);
System.out.println("Add one month to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.YEAR, 1);
System.out.println("Add one year to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.HOUR, 1);
System.out.println("Add one hour to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MINUTE, 1);
System.out.println("Add one minute to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 1);
System.out.println("Add one second to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
System.out.println("Subtract one day from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MONTH, -1);
System.out.println("Subtract one month from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.YEAR, -1);
System.out.println("Subtract one year from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.HOUR, -1);
System.out.println("Subtract one hour from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MINUTE, -1);
System.out.println("Subtract one minute from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.SECOND, -1);
System.out.println("Subtract one second from current date : " + dateFormat.format(cal.getTime()));
Output :

'123004'
Another option would be to set a flag variable as a Boolean
and then change that value based on your criteria.
Dim count as Integer
Dim flag as Boolean
flag = True
While flag
count = count + 1
If count = 10 Then
'Set the flag to false '
flag = false

I think the best and fastest way to do it is:
$first_key=key(array_slice($array, 0, 1, TRUE))
In InnoDB you have START TRANSACTION;
, which in this engine is the officialy recommended way to do transactions, instead of SET AUTOCOMMIT = 0;
(don't use SET AUTOCOMMIT = 0;
for transactions in InnoDB unless it is for optimizing read only transactions). Commit with COMMIT;
.
You might want to use SET AUTOCOMMIT = 0;
in InnoDB for testing purposes, and not precisely for transactions.
In MyISAM you do not have START TRANSACTION;
. In this engine, use SET AUTOCOMMIT = 0;
for transactions. Commit with COMMIT;
or SET AUTOCOMMIT = 1;
(Difference explained in MyISAM example commentary below). You can do transactions this way in InnoDB too.
Source: http://dev.mysql.com/doc/refman/5.6/en/glossary.html#glos_autocommit
Examples of general use transactions:
/* InnoDB */
START TRANSACTION;
INSERT INTO table_name (table_field) VALUES ('foo');
INSERT INTO table_name (table_field) VALUES ('bar');
COMMIT; /* SET AUTOCOMMIT = 1 might not set AUTOCOMMIT to its previous state */
/* MyISAM */
SET AUTOCOMMIT = 0;
INSERT INTO table_name (table_field) VALUES ('foo');
INSERT INTO table_name (table_field) VALUES ('bar');
SET AUTOCOMMIT = 1; /* COMMIT statement instead would not restore AUTOCOMMIT to 1 */

I too get this error sometimes when I dismiss dialog and finish activity from onPostExecute method. I guess sometimes activity gets finished before dialog successfully dismisses.
Simple, yet effective solution that works for me
@Override
protected void onPostExecute(MyResult result) {
try {
if ((this.mDialog != null) && this.mDialog.isShowing()) {
this.mDialog.dismiss();
}
} catch (final IllegalArgumentException e) {
// Handle or log or ignore
} catch (final Exception e) {
// Handle or log or ignore
} finally {
this.mDialog = null;
}
}
Basically, you just have to remove that constraint from the associated view. For instance, if is the height constraint giving warning, just remove it from your view; it will not affect the view.
[Update April 2016] This answer is now outdated, custom naked domain mapping is supported, see Lawrence Mok's answer.
I have figured it out!
First off: it is impossible to link something like mydomain.com
with your appspot app. This is considered a naked domain, which is not supported by Google App Engine (anymore). Strictly speaking, the answer to my question has to be "impossible". Read on...
All you can do is add subdomains pointing to your app, e.g myappid.mydomain.com
. The key to get your top level domain linked to your app is to realize that www
is a subdomain like any other!
myappid.mydomain.com
is treated exactly the same as www.mydomain.com
!
Here are the steps:
www
and click Addwww
for your domain and point to ghs.googlehosted.com
Now you have www.mydomain.com
linked to your app.
I wished this would have been more obvious in the documentation...Good luck!
I disagree!
Why would you ignore the built-in functionality of a for loop to make your own? You do not need to reinvent the wheel.
I think it makes more sense to have your checks at the top of your for loop like so
for(int i = 0; i < myCollection.Length && myCollection[i].SomeValue != "Break Condition"; i++)
{
//loop body
}
or if you need to process the row first
for(int i = 0; i < myCollection.Length && (i == 0 ? true : myCollection[i-1].SomeValue != "Break Condition"); i++)
{
//loop body
}
This way you can write a function to perform everything and make much cleaner code.
for(int i = 0; i < myCollection.Length && (i == 0 ? true : myCollection[i-1].SomeValue != "Break Condition"); i++)
{
DoAllThatCrazyStuff(myCollection[i]);
}
Or if your condition is complicated you can move that code out too!
for(int i = 0; i < myCollection.Length && BreakFunctionCheck(i, myCollection); i++)
{
DoAllThatCrazyStuff(myCollection[i]);
}
"Professional Code" that is riddled with breaks doesn't really sound like professional code to me. It sounds like lazy coding ;)
No, these defines are compiler dependent. What you can do, use your own set of defines, and set them on the Makefile. See this thread for more info.

(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:
GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \
git clone myuser@myGitRemoteServer:/my/remote/git_repo/path
This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).
Make sure you have run the MongoDB's Service before you want to connect the console.
run and start the server:

TCP establishes a connection before the actual data transmission takes place, UDP does not. In this way, UDP can provide faster delivery. Applications like DNS, time server access, therefore, use UDP.
Unlike UDP, TCP uses congestion control. It responses to the network load. Unlike UDP, it slows down when network congestion is imminent. So, applications like multimedia preferring constant throughput might go for UDP.
Besides, UDP is unreliable, it doesn't react on packet losses. So loss sensitive applications like multimedia transmission prefer UDP. However, TCP is a reliable protocol, so, applications that require reliability such as web transfer, email, file download prefer TCP.
Besides, in today's internet UDP is not as welcoming as TCP due to middle boxes. Some applications like skype fall down to TCP when UDP connection is assumed to be blocked.
You have to read the API carefully for this methods. Sometimes you can get confused very easily.
It is either:
if (B.class.isInstance(view))
API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)
or:
if (B.class.isAssignableFrom(view.getClass()))
API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter
or (without reflection and the recommended one):
if (view instanceof B)

You should use the equals
method since this is implemented to perform the comparison you want. toString()
itself uses an iterator just like equals
but it is a more inefficient approach. Additionally, as @Teepeemm pointed out, toString
is affected by order of elements (basically iterator return order) hence is not guaranteed to provide the same output for 2 different maps (especially if we compare two different maps).
Note/Warning: Your question and my answer assume that classes implementing the map interface respect expected toString
and equals
behavior. The default java classes do so, but a custom map class needs to be examined to verify expected behavior.
See: http://docs.oracle.com/javase/7/docs/api/java/util/Map.html
boolean equals(Object o)
Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.
Additionally, java itself takes care of iterating through all elements and making the comparison so you don't have to. Have a look at the implementation of AbstractMap
which is used by classes such as HashMap
:
// Comparison and hashing
/**
* Compares the specified object with this map for equality. Returns
* <tt>true</tt> if the given object is also a map and the two maps
* represent the same mappings. More formally, two maps <tt>m1</tt> and
* <tt>m2</tt> represent the same mappings if
* <tt>m1.entrySet().equals(m2.entrySet())</tt>. This ensures that the
* <tt>equals</tt> method works properly across different implementations
* of the <tt>Map</tt> interface.
*
* <p>This implementation first checks if the specified object is this map;
* if so it returns <tt>true</tt>. Then, it checks if the specified
* object is a map whose size is identical to the size of this map; if
* not, it returns <tt>false</tt>. If so, it iterates over this map's
* <tt>entrySet</tt> collection, and checks that the specified map
* contains each mapping that this map contains. If the specified map
* fails to contain such a mapping, <tt>false</tt> is returned. If the
* iteration completes, <tt>true</tt> is returned.
*
* @param o object to be compared for equality with this map
* @return <tt>true</tt> if the specified object is equal to this map
*/
public boolean equals(Object o) {
if (o == this)
return true;
if (!(o instanceof Map))
return false;
Map<K,V> m = (Map<K,V>) o;
if (m.size() != size())
return false;
try {
Iterator<Entry<K,V>> i = entrySet().iterator();
while (i.hasNext()) {
Entry<K,V> e = i.next();
K key = e.getKey();
V value = e.getValue();
if (value == null) {
if (!(m.get(key)==null && m.containsKey(key)))
return false;
} else {
if (!value.equals(m.get(key)))
return false;
}
}
} catch (ClassCastException unused) {
return false;
} catch (NullPointerException unused) {
return false;
}
return true;
}
toString
fails miserably when comparing a TreeMap
and HashMap
though equals
does compare contents correctly.
Code:
public static void main(String args[]) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("2", "whatever2");
map.put("1", "whatever1");
TreeMap<String, Object> map2 = new TreeMap<String, Object>();
map2.put("2", "whatever2");
map2.put("1", "whatever1");
System.out.println("Are maps equal (using equals):" + map.equals(map2));
System.out.println("Are maps equal (using toString().equals()):"
+ map.toString().equals(map2.toString()));
System.out.println("Map1:"+map.toString());
System.out.println("Map2:"+map2.toString());
}
Output:
Are maps equal (using equals):true
Are maps equal (using toString().equals()):false
Map1:{2=whatever2, 1=whatever1}
Map2:{1=whatever1, 2=whatever2}
Simple:
go in the root folder of the project when this happens and run:
gem install shutup
shutup
This will find the process currently running, kill it and clean up the pid file
NOTE: if you are using rvm install the gem globally
rvm @global do gem install shutup
You can try:
top -bn1 | grep "Cpu(s)" | \
sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | \
awk '{print 100 - $1"%"}'
If you want to run a script to a database:
mysql -u user -p data_base_name_here < db.sql
for me the only thing that works is:
CREATE FUNCTION IsNumeric (SIN VARCHAR(1024)) RETURNS TINYINT
RETURN SIN REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$';

You can use SHOW
:
SHOW max_connections;
This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf
as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf
in your current session:
RESET max_connections;
However, not applicable to this particular setting. The manual:
This parameter can only be set at server start.
To see all settings:
SHOW ALL;
There is also pg_settings
:
The view
pg_settings
provides access to run-time parameters of the server. It is essentially an alternative interface to theSHOW
andSET
commands. It also provides access to some facts about each parameter that are not directly available fromSHOW
, such as minimum and maximum values.
For your original request:
SELECT *
FROM pg_settings
WHERE name = 'max_connections';
Finally, there is current_setting()
, which can be nested in DML statements:
SELECT current_setting('max_connections');

Only providing .ttf file for webfont won't be good enough for cross-browser support. The best possible combination at present is using the combination as :
@font-face {

src: url('webfont.eot'); /* IE9 Compat Modes */
src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */

url('webfont.ttf') format('truetype'), /* Safari, Android, iOS */
url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}
This code assumes you have .eot , .woff , .ttf and svg format for you webfont. To automate all this process , you can use : Transfonter.org.
Also , modern browsers are shifting towards .woff font , so you can probably do this too : :
@font-face {

The best approach to embed a SWF into an HTML page is to use SWFObject.
It is a simple open-source JavaScript library that is easy-to-use and standards-friendly method to embed Flash content.
It also offers Flash player version detection. If the user does not have the version of Flash required or has JavaScript disabled, they will see an alternate content. You can also use this library to trigger a Flash player upgrade. Once the user has upgraded, they will be redirected back to the page.
An example from the documentation:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title>SWFObject dynamic embed - step 3</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF("myContent.swf", "myContent", "300", "120", "9.0.0");
</script>
</head>
<body>
<div id="myContent">
<p>Alternative content</p>
</div>
</body>
</html>
A good tool to use along with this is the SWFObject HTML and JavaScript generator. It basically generates the HTML and JavaScript you need to embed the Flash using SWFObject. Comes with a very simple UI for you to input your parameters.
It Is highly recommended and very simple to use.
The way to dynamically add elements to DOM, as explained on Angular 2 doc, is by using ViewContainerRef class from @Angular/core.
What you have to do is to declare a directive that will implement ViewContainerRef and act like a placeholder on your DOM.
Directive
import { Directive, ViewContainerRef } from '@angular/core';
@Directive({
selector: '[appInject]'
})
export class InjectDirective {
constructor(public viewContainerRef: ViewContainerRef) { }
}
Then, in the template where you want to inject the component:
HTML
<div class="where_you_want_to_inject">
<ng-template appInject></ng-template>
</div>
Then, from the injected component code, you will inject the component containing the HTML you want:
import { Component, OnInit, ViewChild, ComponentFactoryResolver } from '@angular/core';
import { InjectDirective } from '../inject.directive';
import { InjectedComponent } from '../injected/injected.component';
@Component({
selector: 'app-parent',
templateUrl: './parent.component.html',
styleUrls: ['./parent.component.css']
})
export class ParentComponent implements OnInit {
@ViewChild(InjectDirective) injectComp: InjectDirective;
constructor(private _componentFactoryResolver: ComponentFactoryResolver) {
}
ngOnInit() {
}
public addComp() {
const componentFactory = this._componentFactoryResolver.resolveComponentFactory(InjectedComponent);
const viewContainerRef = this.injectComp.viewContainerRef;
const componentRef = viewContainerRef.createComponent(componentFactory);
}
public removeComp() {
const componentFactory = this._componentFactoryResolver.resolveComponentFactory(InjectedComponent);
const viewContainerRef = this.injectComp.viewContainerRef;
const componentRef = viewContainerRef.remove();
}
}
I added a fully working demo app on Angular 2 dynamically add component to DOM demo
You can use assertThrows()
, But with assertThrows
your assertion will pass even if the thrown exception is of child type.
This is because, JUnit 5 checks exception type by calling Class.isIntance(..)
, Class.isInstance(..)
will return true even if the exception thrown is of the child types.
The workaround for this is to assert on Class:
Throwable throwable = assertThrows(Throwable.class, () -> {
service.readFile("sampleFile.txt");
});
assertEquals(FileNotFoundException.class, throwable.getClass());
As of year 2020, JetBrains suggests to commit the .idea
folder.
The JetBrains IDEs (webstorm, intellij, android studio, pycharm, clion, etc.) automatically add that folder to your git repository (if there's one).
Inside the folder .idea
, has been already created a .gitignore
, updated by the IDE itself to avoid to commit user related settings that may contains privacy/password data.
It is safe (and usually useful) to commit the .idea
folder.
Asterisk symbol (*) is used to check values in the array, not the array itself.
$validator = Validator::make($request->all(), [
"names" => "required|array|min:3",
"names.*" => "required|string|distinct|min:3",
]);
In the example above:
EDIT: Since Laravel 5.5 you can call validate() method directly on Request object like so:
$data = $request->validate([
"name" => "required|array|min:3",
"name.*" => "required|string|distinct|min:3",
]);

This linked answer describes a cleaner, simpler way of doing the same thing with C# syntax.

This is Microsoft's recommended way to handle WCF client calls:
For more detail see: Expected Exceptions
try
{
...
double result = client.Add(value1, value2);
...
client.Close();
}
catch (TimeoutException exception)
{
Console.WriteLine("Got {0}", exception.GetType());
client.Abort();
}
catch (CommunicationException exception)
{
Console.WriteLine("Got {0}", exception.GetType());
client.Abort();
}
Additional information
So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:
c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client
Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.
You can try :
@media print {
.table td,
.table th {
background-color: transparent !important;
-webkit-print-color-adjust: exact !important;
}

There are several ways to prevent line breaks in content. Using
is one way, and works fine between words, but using it between an empty element and some text does not have a well-defined effect. The same would apply to the more logical and more accessible approach where you use an image for an icon.
The most robust alternative is to use nobr
markup, which is nonstandard but universally supported and works even when CSS is disabled:
<td><nobr><i class="flag-bfh-ES"></i> +34 666 66 66 66</nobr></td>
(You can, but need not, use
instead of spaces in this case.)
Another way is the nowrap
attribute (deprecated/obsolete, but still working fine, except for some rare quirks):
<td nowrap><i class="flag-bfh-ES"></i> +34 666 66 66 66</td>
Then there’s the CSS way, which works in CSS enabled browsers and needs a bit more code:
<style>
.nobr { white-space: nowrap }
</style>
...
<td class=nobr><i class="flag-bfh-ES"></i> +34 666 66 66 66</td>
In following code, we don't need to hard code the credentials.

You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.

If you want to use AngularJs Directive with dynamic template, you can use those answers,But here is more professional and legal syntax of it.You can use templateUrl not only with single value.You can use it as a function,which returns a value as url.That function has some arguments,which you can use.
In client application (application is not web application, e.g may be swing app)
private static ApplicationContext context = new ClassPathXmlApplicationContext("test-client.xml");
context.getBean(name);
No need of web.xml. ApplicationContext as container for getting bean service. No need for web server container. In test-client.xml there can be Simple bean with no remoting, bean with remoting.
Conclusion: In Scenario 1 applicationContext and DispatcherServlet
are not related.
In a server application (application deployed in server e.g Tomcat). Accessed service via remoting from client program (e.g Swing app)
Define listener in web.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
At server startup ContextLoaderListener
instantiates beans defined in applicationContext.xml.
Assuming you have defined the following in applicationContext.xml:
<import resource="test1.xml" />
<import resource="test2.xml" />
<import resource="test3.xml" />
<import resource="test4.xml" />
The beans are instantiated from all four configuration files test1.xml, test2.xml, test3.xml, test4.xml.
Conclusion: In Scenario 2 applicationContext and DispatcherServlet
are not related.
In a web application with spring MVC.
In web.xml define:
<servlet>
<servlet-name>springweb</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springweb</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
When Tomcat starts, beans defined in springweb-servlet.xml are instantiated.
DispatcherServlet
extends FrameworkServlet
. In FrameworkServlet
bean instantiation takes place for springweb . In our case springweb is FrameworkServlet.
Conclusion: In Scenario 3 applicationContext and DispatcherServlet
are not related.
In web application with spring MVC. springweb-servlet.xml for servlet and applicationContext.xml for accessing the business service within the server program or for accessing DB service in another server program.
In web.xml the following are defined:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springweb</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springweb</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
At server startup, ContextLoaderListener
instantiates beans defined in applicationContext.xml; assuming you have declared herein:
<import resource="test1.xml" />
<import resource="test2.xml" />
<import resource="test3.xml" />
<import resource="test4.xml" />
The beans are all instantiated from all four test1.xml, test2.xml, test3.xml, test4.xml. After the completion of bean instantiation defined in applicationContext.xml, beans defined in springweb-servlet.xml are instantiated.
So the instantiation order is: the root (application context), then FrameworkServlet.
Now it should be clear why they are important in which scenario.
You can use the following solution to accomplish your goal:
struct student
{
char name[20];
char country[20];
};
void main()
{
struct student S={"Wolverine","America"};
struct student X;
X=S;
printf("%s%s",X.name,X.country);
}
this will do it with just javascript - you can also put the function in a .js file and call it with onclick
//button
<div onclick="
document.forms['name_of_the_form']['name_of_the_input'].value += 'text you want to add to it'"
>button</div>
What you probably need to do is redirect the user after the POST / Form Handler script has been ran.
In PHP this is done like so...
<?php
// ... Handle $_POST data, maybe insert it into a database.
// Ok, $_POST data has been handled, redirect the user
header('Location:success.php');
die();
?>
... this should allow you to refresh the page without getting that "Send Data Again" warning.
You can even redirect to the same page (if that's what you're posting to) as the POST variables will not be sent in the headers (and thus not be there to re-POST on refresh)
Yes, the upload element is protected from direct manipulation in different browsers. However, you could erase the element from the DOM tree and then insert a new one in its place via JavaScript. That would give you the same result.
Something along the lines of:
$('#container-element').html('<input id="upload-file" type="file"/>');
In order to downgrade, i had to recompile from source (MacOS Mojave)
$ wget https://ssl.icu-project.org/files/icu4c/62.1/icu4c-62_1-src.tgz
$ tar xvfz icu4c-62_1-src.tgz
$ cd icu/sources
$ ./configure
$ make
$ make install
MDN suggests that there's a much cleaner way of doing this in modern browsers:
// Assuming we're listening for e.g. a 'change' event on `element`
// Create a new 'change' event
var event = new Event('change');
// Dispatch it.
element.dispatchEvent(event);

The term business logic is in my opinion not a precise definition. Evans talks in his book, Domain Driven Design, about two types of business logic:
This separation is in my opinion a lot clearer. And with the realization that there are different types of business rules also comes the realization that they don't all necessarily go the same place.
Domain logic is logic that corresponds to the actual domain. So if you are creating an accounting application, then domain rules would be rules regarding accounts, postings, taxation, etc. In an agile software planning tool, the rules would be stuff like calculating release dates based on velocity and story points in the backlog, etc.
For both these types of application, CSV import/export could be relevant, but the rules of CSV import/export has nothing to do with the actual domain. This kind of logic is application logic.
Domain logic most certainly goes into the model layer. The model would also correspond to the domain layer in DDD.
Application logic however does not necessarily have to be placed in the model layer. That could be placed in the controllers directly, or you could create a separate application layer hosting those rules. What is most logical in this case would depend on the actual application.
You can accomplish this by playing with the opacity of the image and setting the background color of the image to black. By making the image transparent, it will appear darker.
<div class="image">
<img src="http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg" alt="" />
</div>
CSS:
.image { position: relative; border: 1px solid black; width: 200px; height: 200px; background: black; }
.image img { max-width: 100%; max-height: 100%; }
.image img:hover { opacity: .5 }
You might need to set the browser-specific opacity too to make this work in other browsers too.
Update the 'apache-tomcat-8.5.5\conf\tomcat-users.xml file. uncomment the roles and add/replace the following line.and restart server
tomcat-users.xml file
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="standard,manager,admin,manager-gui,manager-script"/>
You can also do it if you use the exit()
function in your code. More ideally, you can do sys.exit()
. sys.exit()
which might terminate Python even if you are running things in parallel through the multiprocessing
package.
Note: In order to use the sys.exit()
, you must import it: import sys
PDFJet offers an open-source version of their library that should be able to handle any basic PDF generation task. It's a purely Java-based solution and it is stated to be compatible with Android. There is a commercial version with some additional features that does not appear to be too expensive.
What you're doing is creating a temporary. That temporary exists in a scope determined by the compiler, such that it's long enough to satisfy the requirements of where it's going.
As soon as the statement const char* cstr2 = ss.str().c_str();
is complete, the compiler sees no reason to keep the temporary string around, and it's destroyed, and thus your const char *
is pointing to free'd memory.
Your statement string str(ss.str());
means that the temporary is used in the constructor for the string
variable str
that you've put on the local stack, and that stays around as long as you'd expect: until the end of the block, or function you've written. Therefore the const char *
within is still good memory when you try the cout
.
You are likely to use in the code a variable named model
.
Almost there! The escape sequence for a brace is {{
or }}
so for your example you would use:
string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);
Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:
str = str.replace(/[^-a-z0-9]+/g, "");
Also, if you need to match upper-case letters along with lower case, you should use:
str = str.replace(/[^-a-zA-Z0-9]+/g, "");
{{ (ability.id in company_abilities) ? 'selected' : '' }}
The ternary operator is documented under 'other operators'
It's because, even in "raw" strings (=strings with an r
before the starting quote(s)), an unescaped escape character cannot be the last character in the string. This should work instead:
'\\ '[0]

That character is the BOM or "Byte Order Mark". It is usually received as the first few bytes of a file, telling you how to interpret the encoding of the rest of the data. You can simply remove the character to continue. Although, since the error says you were trying to convert to 'ascii', you should probably pick another encoding for whatever you were trying to do.

I was able to resolve this error which said "158 duplicate symbols for architecture armv7, 158 duplicate symbols for architecture arm64" --- If this is what you are getting too, then it means you are trying to compile a file which is importing or inheriting a framework or static library having references to C++ code or files. An easy way to handle this would be to change the extension of your .m file to .mm. This is how it gets handled if you are using Objective C, not sure on Swift though.
Also in your build settings - you can update the "other linker flags" to -lc++
as long as "lots of stuff" isn't doing something asynchronous this is absolutely unneccessary - the event will call every handler on his way in sequence, so if theres a onklick-event on a parent-element this will fire after the onclik-event of the child has processed completely. javascript doesn't do some kind of "multithreading" here that makes "stopping" the event processing neccessary. conclusion: "pausing" an event just to resume it in the same handler doesn't make any sense.
if "lots of stuff" is something asynchronous this also doesn't make sense as it prevents the asynchonous things to do what they should do (asynchonous stuff) and make them bahave like everything is in sequence (where we come back to my first paragraph)
You do not need to activate the sheet (you'll take a huge performance hit for doing so, actually). Since you are declaring an object for the sheet, when you call the method starting with "wb." you are selecting that object. For example, you can jump in between workbooks without activating anything like here:
Sub Test()
Dim wb1 As Excel.Workbook
Set wb1 = Workbooks.Open("C:\Documents and Settings\xxxx\Desktop\test1.xls")
Dim wb2 As Excel.Workbook
Set wb2 = Workbooks.Open("C:\Documents and Settings\xxxx\Desktop\test2.xls")
wb1.Sheets("Sheet1").Cells(1, 1).Value = 24
wb2.Sheets("Sheet1").Cells(1, 1).Value = 24
wb1.Sheets("Sheet1").Cells(2, 1).Value = 54
End Sub
The result of floating point number is not exact, which makes them unsuitable for any financial calculation which requires exact result and not approximation. float and double are designed for engineering and scientific calculation and many times doesn’t produce exact result also result of floating point calculation may vary from JVM to JVM. Look at below example of BigDecimal and double primitive which is used to represent money value, its quite clear that floating point calculation may not be exact and one should use BigDecimal for financial calculations.
// floating point calculation
final double amount1 = 2.0;
final double amount2 = 1.1;
System.out.println("difference between 2.0 and 1.1 using double is: " + (amount1 - amount2));
// Use BigDecimal for financial calculation
final BigDecimal amount3 = new BigDecimal("2.0");
final BigDecimal amount4 = new BigDecimal("1.1");
System.out.println("difference between 2.0 and 1.1 using BigDecimal is: " + (amount3.subtract(amount4)));
Output:
difference between 2.0 and 1.1 using double is: 0.8999999999999999
difference between 2.0 and 1.1 using BigDecimal is: 0.9

There is too much problem of setting up environmental variables. It worked for me.
Hope this helps.

Don't know why, my Neon Eclipse still having this issue, it doesn't seem to be fixed in Mars version as many people said.
I found that using command is too troublesome, I delete the plugin away via the Eclipse Installation Manager.
Just select the plugin "Dali Java Persistence Tools -JPA Support" and click "uninstall" will do. Please take note my screen below doesn't have that because I already uninstalled.
Use android:background property for that edittext. Pass your drawable folder image to it. For example,
android:background="@drawable/abc.png"
As an addition to Darin Dimitrov's answer:
If you only want this particular line to use a certain (different from standard) format, you can use in MVC5:
@Html.EditorFor(model => model.Property, new {htmlAttributes = new {@Value = @Model.Property.ToString("yyyy-MM-dd"), @class = "customclass" } })
You could try this
let count = s.length - s.replace(/is/g, "").length;
Tried all of the above and nothing worked so I used npm i react-scripts
and it worked
Instead of parsing day, month and year you can specify date formats directly using datepicker's formatDate function. In my example I am using "yy-mm-dd", but you can use any format of your choice.
$("#datepicker").datepicker({
dateFormat: 'yy-mm-dd',
inline: true,
minDate: new Date(2010, 1 - 1, 1),
maxDate: new Date(2010, 12 - 1, 31),
altField: '#datepicker_value',
onSelect: function(){
var fullDate = $.datepicker.formatDate("yy-mm-dd", $(this).datepicker('getDate'));
var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
$('#page_output').html(str_output);
}
});
I'm getting an error in the IF conditional. What am I doing wrong?
There reason that you get a SyntaxError
is that there is no &&
operator in Python. Likewise ||
and !
are not valid Python operators.
Some of the operators you may know from other languages have a different name in Python.
The logical operators &&
and ||
are actually called and
and or
.
Likewise the logical negation operator !
is called not
.
So you could just write:
if len(a) % 2 == 0 and len(b) % 2 == 0:
or even:
if not (len(a) % 2 or len(b) % 2):
I summarized the operator "equivalents" in this table:
+------------------------------+---------------------+
| Operator (other languages) | Operator (Python) |
+==============================+=====================+
| && | and |
+------------------------------+---------------------+
| || | or |
+------------------------------+---------------------+
| ! | not |
+------------------------------+---------------------+
See also Python documentation: 6.11. Boolean operations.
Besides the logical operators Python also has bitwise/binary operators:
+--------------------+--------------------+
| Logical operator | Bitwise operator |
+====================+====================+
| and | & |
+--------------------+--------------------+
| or | | |
+--------------------+--------------------+
There is no bitwise negation in Python (just the bitwise inverse operator ~
- but that is not equivalent to not
).
See also 6.6. Unary arithmetic and bitwise/binary operations and 6.7. Binary arithmetic operations.
The logical operators (like in many other languages) have the advantage that these are short-circuited. That means if the first operand already defines the result, then the second operator isn't evaluated at all.
To show this I use a function that simply takes a value, prints it and returns it again. This is handy to see what is actually evaluated because of the print statements:
>>> def print_and_return(value):
... print(value)
... return value
>>> res = print_and_return(False) and print_and_return(True)
False
As you can see only one print statement is executed, so Python really didn't even look at the right operand.
This is not the case for the binary operators. Those always evaluate both operands:
>>> res = print_and_return(False) & print_and_return(True);
False
True
But if the first operand isn't enough then, of course, the second operator is evaluated:
>>> res = print_and_return(True) and print_and_return(False);
True
False
To summarize this here is another Table:
+-----------------+-------------------------+
| Expression | Right side evaluated? |
+=================+=========================+
| `True` and ... | Yes |
+-----------------+-------------------------+
| `False` and ... | No |
+-----------------+-------------------------+
| `True` or ... | No |
+-----------------+-------------------------+
| `False` or ... | Yes |
+-----------------+-------------------------+
The True
and False
represent what bool(left-hand-side)
returns, they don't have to be True
or False
, they just need to return True
or False
when bool
is called on them (1).
So in Pseudo-Code(!) the and
and or
functions work like these:
def and(expr1, expr2):
left = evaluate(expr1)
if bool(left):
return evaluate(expr2)
else:
return left
def or(expr1, expr2):
left = evaluate(expr1)
if bool(left):
return left
else:
return evaluate(expr2)
Note that this is pseudo-code not Python code. In Python you cannot create functions called and
or or
because these are keywords.
Also you should never use "evaluate" or if bool(...)
.
This implicit bool
call can be used to customize how your classes behave with and
, or
and not
.
To show how this can be customized I use this class which again print
s something to track what is happening:
class Test(object):
def __init__(self, value):
self.value = value
def __bool__(self):
print('__bool__ called on {!r}'.format(self))
return bool(self.value)
__nonzero__ = __bool__ # Python 2 compatibility
def __repr__(self):
return "{self.__class__.__name__}({self.value})".format(self=self)
So let's see what happens with that class in combination with these operators:
>>> if Test(True) and Test(False):
... pass
__bool__ called on Test(True)
__bool__ called on Test(False)
>>> if Test(False) or Test(False):
... pass
__bool__ called on Test(False)
__bool__ called on Test(False)
>>> if not Test(True):
... pass
__bool__ called on Test(True)
If you don't have a __bool__
method then Python also checks if the object has a __len__
method and if it returns a value greater than zero.
That might be useful to know in case you create a sequence container.
See also 4.1. Truth Value Testing.
Probably a bit beyond the scope of the original question but in case you're dealing with NumPy arrays or subclasses (like Pandas Series or DataFrames) then the implicit bool
call
will raise the dreaded ValueError
:
>>> import numpy as np
>>> arr = np.array([1,2,3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> arr and arr
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> import pandas as pd
>>> s = pd.Series([1,2,3])
>>> bool(s)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> s and s
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
In these cases you can use the logical and function from NumPy which performs an element-wise and
(or or
):
>>> np.logical_and(np.array([False,False,True,True]), np.array([True, False, True, False]))
array([False, False, True, False])
>>> np.logical_or(np.array([False,False,True,True]), np.array([True, False, True, False]))
array([ True, False, True, True])
If you're dealing just with boolean arrays you could also use the binary operators with NumPy, these do perform element-wise (but also binary) comparisons:
>>> np.array([False,False,True,True]) & np.array([True, False, True, False])
array([False, False, True, False])
>>> np.array([False,False,True,True]) | np.array([True, False, True, False])
array([ True, False, True, True])
(1)
That the bool
call on the operands has to return True
or False
isn't completely correct. It's just the first operand that needs to return a boolean in it's __bool__
method:
class Test(object):
def __init__(self, value):
self.value = value
def __bool__(self):
return self.value
__nonzero__ = __bool__ # Python 2 compatibility
def __repr__(self):
return "{self.__class__.__name__}({self.value})".format(self=self)
>>> x = Test(10) and Test(10)
TypeError: __bool__ should return bool, returned int
>>> x1 = Test(True) and Test(10)
>>> x2 = Test(False) and Test(10)
That's because and
actually returns the first operand if the first operand evaluates to False
and if it evaluates to True
then it returns the second operand:
>>> x1
Test(10)
>>> x2
Test(False)
Similarly for or
but just the other way around:
>>> Test(True) or Test(10)
Test(True)
>>> Test(False) or Test(10)
Test(10)
However if you use them in an if
statement the if
will also implicitly call bool
on the result. So these finer points may not be relevant for you.
Has anyone mentioned std::call_once
and std::once_flag
?
Most other approaches - including double checked locking - are broken.
One major problem in singleton pattern implementation is safe initialization. The only safe way is to guard the initialization sequence with synchronizing barriers. But those barriers themselves need to be safely initiated. std::once_flag
is the mechanism to get guaranteed safe initialization.
You need to add the "global" flag to your regex:
s.replace(new RegExp("[0-9]", "g"), "X")
or, perhaps prettier, using the built-in literal regexp syntax:
.replace(/[0-9]/g, "X")
Total Commander also has a binary compare option:
go to: File \\Compare by content
ps. I guess some people may alredy be using this tool and may not be aware of the built-in feature.
genrsa
has been replaced by genpkey
& when run manually in a terminal it will prompt for a password:
openssl genpkey -aes-256-cbc -algorithm RSA -out /etc/ssl/private/key.pem -pkeyopt rsa_keygen_bits:4096
However when run from a script the command will not ask for a password so to avoid the password being viewable as a process use a function in a shell
script:
get_passwd() {
local passwd=
echo -ne "Enter passwd for private key: ? "; read -s passwd
openssl genpkey -aes-256-cbc -pass pass:$passwd -algorithm RSA -out $PRIV_KEY -pkeyopt rsa_keygen_bits:$PRIV_KEYSIZE
}
If you want to use C++ streams rather than C functions, you can do the following:
int ar[] = { 20, 30, 40, 50, 60, 70, 80, 90 };
const int siz_ar = sizeof(ar) / sizeof(int);
for (int i = 0; i < siz_ar; ++i)
cout << ar[i] << " ";
cout << endl;
for (int i = 0; i < siz_ar; ++i)
cout << hex << setfill('0') << setw(2) << ar[i] << " ";
cout << endl;
Very simple.
Output:
20 30 40 50 60 70 80 90
14 1e 28 32 3c 46 50 5a

I had an issue somebody made a revert to master to my branch, but I was needed to be able to merge it again but the problem is that the revert included all my commit. Lets look at that case we created our feature branch from M1 we merge our feature branch in M3 and revert on it in RM3
M1 -> M2 -> M3 -> M4- > RM3 -> M5
\. /
F1->F2 -
How to make the F2 able to merge to M5?
git checkout master
git checkout -b brach-before-revert
git reset --hard M4
git checkout master
git checkout -b new-feature-branch
git reset --hard M1
git merge --squash brach-before-revert
You need one project per language. I'm quite confident I saw a tool that merged assemblies, if you find that tool you should be good to go. If you need to use both languages in the same class, you should be able to write half of it in say VB.net and then write the rest in C# by inheriting the VB.net class.

I had this problem before and to fix this, Just make sure :
My problem (before) :
I had class : Core, Router, Permissions and Render
Core include's the Router class, Router then calls Permissions class, then Router __destruct calls the Render class and the error "Cannot declare class because the name is already in use" appeared.
Solution :
I added __destruct on Permission class and the __destruct was empty and it's fixed...
Eclipse is suggesting you to define generic type
so that you can have type safety
. You can write
Map m = new HashMap();
which does not ensure type safety but following will ensure type safety
Map<Object,Object> = new HashMap<Object,Object>();
The Object
can be any type such as String
, Integer
etc.
You can use the getchar routine.
From the above link:
/* getchar example : typewriter */
#include <stdio.h>
int main ()
{
char c;
puts ("Enter text. Include a dot ('.') in a sentence to exit:");
do {
c=getchar();
putchar (c);
} while (c != '.');
return 0;
}
You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet
of Note
s, where you need to pass in a single Note
.
You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note
@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

When attempting to write to the destination image using any of these answers above and you get the following error:
ValueError: assignment destination is read-only
A quick potential fix is to set the WRITEABLE flag to true.
img.setflags(write=1)
If you have this:
A - B <- mybranch
Where you have committed some content in commit B:
/modules/a/file1
/modules/a/file2
/modules/b/file3
/modules/b/file4
But you want to split B into C - D, and get this result:
A - C - D <-mybranch
You can divide the content like this for example (content from different directories in different commits)...
Reset the branch back to the commit before the one to split:
git checkout mybranch
git reset --hard A
Create first commit (C):
git checkout B /modules/a
git add -u
git commit -m "content of /modules/a"
Create second commit (D):
git checkout B /modules/b
git add -u
git commit -m "content of /modules/b"
Adding this answer as I had to lookup multiple places to achieve my use case. I had a script that runs on startup. This script runs process as a specific (passwordless) user and is running on multiple linux flavors. Here are options on different flavors: (I have taken java as target process for example)
1. RHEL / CentOS 6:
source /etc/rc.d/init.d/functions
daemon --user=myUser $JAVA_HOME/bin/java
2. RHEL 7 / SUSE12 / other linux flavors where systemd is used:
In your systemd unit file add:
User=myUser
3. Suse 11:
/sbin/startproc -u myUser $JAVA_HOME/bin/java
One thing that needs to be mentioned. You have to use the x86 version of Python 2.7. OpenCV doesn't support Python x64. I banged my head on this for a bit until I figured that out.
That said, follow the steps in Abid Rahman K's answer. And as Antimony said, you'll need to do a 'from cv2 import cv'
When converting an ASP.Net webform prototype to a MVC site I got these errors:
TypeError: $(...).accordion is not a function
$("#accordion").accordion(
$('#dialog').dialog({
TypeError: $(...).dialog is not a function
It worked fine in the webforms. The problem/solution was this line in the _Layout.cshtml
@Scripts.Render("~/bundles/jquery")
Comment it out to see if the errors go away. Then fix it in the BundlesConfig:
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
On my AIX system, I tried
nohup -p processid>
This worked well. It continued to run my process even after closing terminal windows. We have ksh as default shell so the bg
and disown
commands didn't work.
If you prefer splitting a CSV list in SQL, there's a different way to do it using Common Table Expressions (CTEs). See Efficient way to string split using CTE.
I know this question is old, but the way I found the executable file for a similar application was to first open the application, then open Windows Task Manager, and in the "Processes" list right-click on it and choose "Open File Location".
I couldn't seem to find the location in the application reference file in my case...
Repo full name:
git config --get remote.origin.url | grep -Po "(?<=git@github\.com:)(.*?)(?=.git)"
I have also come across this issue whilst upgrading from Java 1.6_29 to 1.7.
Alarmingly, my customer has discovered a setting in the Java control panel which resolves this.
In the Advanced Tab you can check 'Use SSL 2.0 compatible ClientHello format'.
This seems to resolve the issue.
We are using Java applets in an Internet Explorer browser.
Hope this helps.
If you get the the text inside the element use
$(".element-classname").text();
In your code:
$('.HOEnZb').text();
if you want get all the data including html Tags use:
$(".element-classname").html();
In your code:
$('.HOEnZb').html();
Hope it helps:)
I encountered another problem that returns the same error.
I used a json string with single quotes :
{
'property': 1
}
But json.loads
accepts only double quotes for json properties :
{
"property": 1
}
json.loads
doesn't accept a final comma:
{
"property": "text",
"property2": "text2",
}
ast
to solve single quote and final comma issuesYou can use ast
(part of standard library for both Python 2 and 3) for this processing. Here is an example :
import ast
# ast.literal_eval() return a dict object, we must use json.dumps to get JSON string
import json
# Single quote to double with ast.literal_eval()
json_data = "{'property': 'text'}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}
# ast.literal_eval() with double quotes
json_data = '{"property": "text"}'
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}
# ast.literal_eval() with final coma
json_data = "{'property': 'text', 'property2': 'text2',}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property2": "text2", "property": "text"}
Using ast
will prevent you from single quote and final comma issues by interpet the JSON like Python dictionnary (so you must follow the Python dictionnary syntax). It's a pretty good and safely alternative of eval()
function for literal structures.
Python documentation warned us of using large/complex string :
Warning It is possible to crash the Python interpreter with a sufficiently large/complex string due to stack depth limitations in Python’s AST compiler.
To use json.dumps
with single quotes easily you can use this code:
import ast
import json
data = json.dumps(ast.literal_eval(json_data_single_quote))
ast
documentationIf you frequently edit JSON, you may use CodeBeautify. It helps you to fix syntax error and minify/beautify JSON.
I hope it helps.

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.
