Edit /etc/sudoers
file either manually or using the visudo application.
Remember: System reads /etc/sudoers
file from top to the bottom, so you could overwrite a particular setting by putting the next one below.
So to be on the safe side - define your access setting at the bottom.
Drive letters can be used in the target like
scp some_file user@host:/c/temp
where c
is the drive letter. It's treated like a directory.
Maybe this works on the source, too.
Set SSH up for Public Key Authentication, with no pasphrase on the Key. Loads of guides on the net. You won't need a password to login then. You can then limit connections for a key based on client hostname. Provides reasonable security and is great for automated logins.
Another way is to make your user a password-less sudo user
.
Type the following on command line:
sudo visudo
Then add the following and replace the <username>
with yours:
<username> ALL=(ALL) NOPASSWD: ALL
This will allow the user to execute sudo
command without having to ask for password (including application launched by the said user. This might be a security risk though
Ok this is my solution: in ~/.bash_aliases just add the following:
# ADDS MY PATH WHEN SET AS ROOT
if [ $(id -u) = "0" ]; then
export PATH=$PATH:/home/your_user/bin
fi
Voila! Now you can execute your own scripts with sudo or set as ROOT without having to do an export PATH=$PATH:/home/your_user/bin everytime.
Notice that I need to be explicit when adding my PATH since HOME for superuser is /root
How about writing a script?
Filename: myscript
#!/bin/sh
/bin/ls -lah /root > /root/test.out
# end script
Then use sudo to run the script:
sudo ./myscript
If you would like to handle quotes:
sudo -s -- <<EOF
id
pwd
echo "Done."
EOF
This is an annoying function a feature of sudo on many distributions.
To work around this "problem" on ubuntu I do the following in my ~/.bashrc
alias sudo='sudo env PATH=$PATH'
Note the above will work for commands that don't reset the $PATH themselves. However `su' resets it's $PATH so you must use -p to tell it not to. I.E.:
sudo su -p
File sutest
#!/bin/bash
echo "uid is ${UID}"
echo "user is ${USER}"
echo "username is ${USERNAME}"
run it: `./sutest' gives me
uid is 500
user is stephenp
username is stephenp
but using sudo: sudo ./sutest
gives
uid is 0
user is root
username is stephenp
So you retain the original user name in $USERNAME when running as sudo. This leads to a solution similar to what others posted:
#!/bin/bash
sudo -u ${USERNAME} normal_command_1
root_command_1
root_command_2
sudo -u ${USERNAME} normal_command_2
# etc.
Just sudo to invoke your script in the first place, it will prompt for the password once.
I originally wrote this answer on Linux, which does have some differences with OS X
OS X (I'm testing this on Mountain Lion 10.8.3) has an environment variable SUDO_USER
when you're running sudo, which can be used in place of USERNAME
above, or to be more cross-platform the script could check to see if SUDO_USER is set and use it if so, or use USERNAME if that's set.
Changing the original script for OS X, it becomes...
#!/bin/bash
sudo -u ${SUDO_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${SUDO_USER} normal_command_2
# etc.
A first stab at making it cross-platform could be...
#!/bin/bash
#
# set "THE_USER" to SUDO_USER if that's set,
# else set it to USERNAME if THAT is set,
# else set it to the string "unknown"
# should probably then test to see if it's "unknown"
#
THE_USER=${SUDO_USER:-${USERNAME:-unknown}}
sudo -u ${THE_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${THE_USER} normal_command_2
# etc.
Watch OUT!!! Watch OUT!!! Watch OUT!!!
chown or chmod is NOT the solution, because of security-risk.
Instead do this, do:
First check, where npm point to, if you call:
npm config get prefix
If /usr is returned, you can do the following:
mkdir ~/.npm-global
export NPM_CONFIG_PREFIX=~/.npm-global
export PATH=$PATH:~/.npm-global/bin
This create a npm-Directory in your Home-Directory and point npm
to it.
To got this changes permanent, you have to add the export-command to your .bashrc:
echo -e "export NPM_CONFIG_PREFIX=~/.npm-global\nexport PATH=\$PATH:~/.npm-global/bin" >> ~/.bashrc
As stated in an article by Slicehost:
User setup
So let's start by adding the main user to the Apache user group:
sudo usermod -a -G www-data demo
That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.
You will need to log out and log back in again to enable the group change.
Check the groups now:
groups ... # demo www-data
So now I am a member of two groups: My own (demo) and the Apache group (www-data).
Folder setup
Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).
Let's set that up:
sudo chgrp -R www-data /home/demo/public_html
As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.
If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.
Setgid
Good so far, but remember the command we just gave only affects existing folders. What about anything new?
We can set the ownership so anything new is also in the 'www-data' group.
The first command will change the permissions for the public_html directory to include the "setgid" bit:
sudo chmod 2750 /home/demo/public_html
That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.
If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:
sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads
The permissions only need to be set once as new files will automatically be assigned the correct ownership.
sudo
is a Unix/Linux command. It's not available in Windows.
If you altered your $PATH variable that could also cause the problem. If you think that might be the issue, check your ~/.bash_profile or ~/.bashrc
Or install syswin package, which includes a port of su for cygwin: http://sourceforge.net/p/manufacture/wiki/syswin-su/
I think your compiled coffee script is missing from the published npm package. Try writing a prepublish command.
Unlike accepted answer, I use usermod
instead.
Assume already logged-in as root in docker, and "fruit" is the new non-root username I want to add, simply run this commands:
apt update && apt install sudo
adduser fruit
usermod -aG sudo fruit
Remember to save image after update. Use docker ps
to get current running docker's <CONTAINER ID> and <IMAGE>, then run docker commit -m "added sudo user" <CONTAINER ID> <IMAGE>
to save docker image.
Then test with:
su fruit
sudo whoami
Or test by direct login(ensure save image first) as that non-root user when launch docker:
docker run -it --user fruit <IMAGE>
sudo whoami
You can use sudo -k
to reset password prompt timestamp:
sudo whoami # No password prompt
sudo -k # Invalidates the user's cached credentials
sudo whoami # This will prompt for password
A summary (and very minor improvement) on the most common answers that I found for this as at 2020.
Call with :w!!
or :W!!
.
After it expands, press enter
.
!!
after the w/W, it will not expand and might report: E492: Not an editor command: W!!
NOTE Use which tee
output to replace /usr/bin/tee
if it differs in your case.
Put these in your ~/.vimrc
file:
" Silent version of the super user edit, sudo tee trick.
cnoremap W!! execute 'silent! write !sudo /usr/bin/tee "%" >/dev/null' <bar> edit!
" Talkative version of the super user edit, sudo tee trick.
cmap w!! w !sudo /usr/bin/tee >/dev/null "%"
First, the linked answer below was about the only other that seemed to mitigate most known problems and differ in any significant way from the others. Worth reading: https://stackoverflow.com/a/12870763/2927555
My answer above was pulled together from multiple suggestions on the conventional sudo tee theme and thus very slightly improves on the most common answers I found. My version above:
Works with whitespace in file names
Mitigates path modification attacks by specifying the full path to tee.
Gives you two mappings, W!! for silent execution, and w!! for not silent, i.e Talkative :-)
The difference in using the non-silent version is that you get to choose between [O]k and [L]oad. If you don't care, use the silent version.
Information for the above was drawn from a bunch of other answers and comments on this, but notably:
Dr Beco's answer: https://stackoverflow.com/a/48237738/2927555
idbrii's comment to this: https://stackoverflow.com/a/25010815/2927555
Han Seoul-Oh's comment to this: How does the vim "write with sudo" trick work?
Bruno Bronosky comment to this: https://serverfault.com/a/22576/195239
This answer also explains why the apparently most simple approach is not such a good idea: https://serverfault.com/a/26334/195239
echo 'Hello World' | (sudo tee -a /etc/apt/sources.list)
I faced a problem,
user1@server1$ ssh -q user1@server2 sudo -u user2 rm -f /some/file/location.txt
Output:
sudo: no tty present and no askpass program specified
Then I tried with
#1
vim /etc/sudoers
Defaults:user1 !requiretty
didn't work
#2
user1 ALL=(user2) NOPASSWD: ALL
that worked properly!
Use sudo
instead
EDIT: As Douglas pointed out, you can not use cd
in sudo
since it is not an external command. You have to run the commands in a subshell to make the cd
work.
sudo -u $USERNAME -H sh -c "cd ~/$PROJECT; svn update"
sudo -u $USERNAME -H cd ~/$PROJECT
sudo -u $USERNAME svn update
You may be asked to input that user's password, but only once.
Call visudo
and add this:
user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh
The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh
from a user1
shell. Done.
Your original problem is that pip cannot write the logs to the folder.
IOError: [Errno 13] Permission denied: '/Users/markwalker/Library/Logs/pip.log'
You need to cd into a folder in which the process invoked can write like /tmp
so a cd /tmp
and re invoking the command will probably work but is not what you want.
BUT actually for this particular case (you not wanting to use sudo
for installing python packages) and no need for global package installs you can use the --user
flag like this :
pip install --user <packagename>
and it will work just fine.
I assume you have a one user python python installation and do not want to bother with reading about virtualenv (which is not very userfriendly) or pipenv.
As some people in the comments section have pointed out the next approach is not a very good idea unless you do not know what to do and got stuck:
Another approach for global packages like in your case you want to do something like :
chown -R $USER /Library/Python/2.7/site-packages/
or more generally
chown -R $USER <path to your global pip packages>
Usually all users will have write access to /tmp. Place the file to /tmp and then login to putty , then you can sudo and copy the file.
One option is to use the -A flag to sudo. This runs a program to ask for the password. Rather than ask, you could have a script that just spits out the password so the program can continue.
In a simple manner you can also try to just run a pre-packaged docker with intellij, I found the good job of @dlsniper : https://hub.docker.com/r/dlsniper/docker-intellij/
you just need to have docker installed and to run :
docker run -tdi \
--net="host" \
--privileged=true \
-e DISPLAY=${DISPLAY} \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-v ${HOME}/.IdeaIC2016.1_docker:/home/developer/.IdeaIC2016.1 \
-v ${GOPATH}:/home/developer/go \
dlsniper/docker-intellij
This might be super edge case, but if you are using Travis CI and taking advantage of caching, you might want to clear all cache and retry.
Fixed my issue when I was going from sudo to non sudo builds.
If you have the need to keep the environment variables in a script you can put your command in a here document like this. Especially if you have lots of variables to set things look tidy this way.
# prepare a script e.g. for running maven
runmaven=/tmp/runmaven$$
# create the script with a here document
cat << EOF > $runmaven
#!/bin/bash
# run the maven clean with environment variables set
export ANT_HOME=/usr/share/ant
export MAKEFLAGS=-j4
mvn clean install
EOF
# make the script executable
chmod +x $runmaven
# run it
sudo $runmaven
# remove it or comment out to keep
rm $runmaven
I faced this issue when working on an Ubuntu 20.04 server.
I was trying to run a sudo
command from a remote machine to deploy an app to the server. However when I run the command I get the error:
sudo: no tty present and no askpass program specified
The remote script failed with exit code 1
Here's how I fixed it:
The issue is caused by executing a sudo
command which tries to request for a password, but sudo
does not have access to a tty
to prompt the user for a passphrase. As it can’t find a tty
, sudo
falls back to an askpass
method but can’t find an askpass
command configured, so the sudo
command fails.
To fix this you need to be able to run sudo
for that specific user with no password requirements. The no password requirements is configured in the /etc/sudoers
file. To configure it run either of the commands below:
sudo nano /etc/sudoers
OR
sudo visudo
Note: This opens the /etc/sudoers
file using your default editor.
Next, Add the following line at the bottom of the file:
# Allow my_user to run all commands without password
my_user ALL=(ALL) NOPASSWD:ALL
Note: Replace my_user
with your actual user
If you want the user to run specific commands you can specify them
# Allow my_user to run specific commands without password
my_user ALL=(ALL) NOPASSWD:/bin/myCommand
OR
# Allow my_user to run specific commands without password
my_user ALL=(ALL) NOPASSWD: /bin/myCommand, /bin/myCommand, /bin/myCommand
Save the changes and exit the file.

That's all.

The best secure method is to use the crontab. ie Save all your commands in a database say, mysql table and create a cronjob to read these mysql entreis and execute via exec() or shell_exec(). Please read this link for more detailed information.
A handle is a pointer or index with no visible type attached to it. Usually you see something like:
typedef void* HANDLE;
HANDLE myHandleToSomething = CreateSomething();
So in your code you just pass HANDLE around as an opaque value.
In the code that uses the object, it casts the pointer to a real structure type and uses it:
int doSomething(HANDLE s, int a, int b) {
Something* something = reinterpret_cast<Something*>(s);
return something->doit(a, b);
}
Or it uses it as an index to an array/vector:
int doSomething(HANDLE s, int a, int b) {
int index = (int)s;
try {
Something& something = vecSomething[index];
return something.doit(a, b);
} catch (boundscheck& e) {
throw SomethingException(INVALID_HANDLE);
}
}
Did you try it without the WSGIDaemonProcess option?
I had no trouble setting up mod_wsgi at home, but did it without the daemon option. You mentioned solving by moving around virtual hosts files and I note this caveat in the docs for WSGIDaemonProcess:
Also note that the name of the daemon process group must be unique for the whole server. That is, it is not possible to use the same daemon process group name in different virtual hosts.
Don't know if that's coincidence.

I wrote a very simple function that uses jQuery to iterate the elements wrapping each keyword with a .highlight class.
function highlight_words(word, element) {
if(word) {
var textNodes;
word = word.replace(/\W/g, '');
var str = word.split(" ");
$(str).each(function() {
var term = this;
var textNodes = $(element).contents().filter(function() { return this.nodeType === 3 });
textNodes.each(function() {
var content = $(this).text();
var regex = new RegExp(term, "gi");
content = content.replace(regex, '<span class="highlight">' + term + '</span>');
$(this).replaceWith(content);
});
});
}
}
More info:
Alternate Solution :
reduce(lambda x,y : filter(lambda z: z!=y,x) ,[2,3,5,8],[1,2,6,8])
This solution also avoids hasOwnProperty()
as Object.keys returns an array of a given object's own enumerable properties.
Object.keys(obj).forEach(function (key) {
if(typeof obj[key] === 'undefined'){
delete obj[key];
}
});
and you can add this as null
or ''
for stricter cleaning.
You have to log the responseText:
$.ajax({

.done(

}
)
.fail(function (data) {
console.log( "Ajax failed: " + data['responseText'] );
})

If you have a Unicode string, and you want to write this to a file, or other serialised form, you must first encode it into a particular representation that can be stored. There are several common Unicode encodings, such as UTF-16 (uses two bytes for most Unicode characters) or UTF-8 (1-4 bytes / codepoint depending on the character), etc. To convert that string into a particular encoding, you can use:
>>> s= u'£10'
>>> s.encode('utf8')
'\xc2\x9c10'
>>> s.encode('utf16')
'\xff\xfe\x9c\x001\x000\x00'
This raw string of bytes can be written to a file. However, note that when reading it back, you must know what encoding it is in and decode it using that same encoding.
When writing to files, you can get rid of this manual encode/decode process by using the codecs module. So, to open a file that encodes all Unicode strings into UTF-8, use:
import codecs
f = codecs.open('path/to/file.txt','w','utf8')
f.write(my_unicode_string) # Stored on disk as UTF-8
Do note that anything else that is using these files must understand what encoding the file is in if they want to read them. If you are the only one doing the reading/writing this isn't a problem, otherwise make sure that you write in a form understandable by whatever else uses the files.
In Python 3, this form of file access is the default, and the built-in open
function will take an encoding parameter and always translate to/from Unicode strings (the default string object in Python 3) for files opened in text mode.
This is the correct answer. It will refresh the previous page.

tempDF = pd.DataFrame(rows,columns=['id','min_date'])
InfoDF = pd.concat([InfoDF,tempDF])
The Java runtime you try to execute your program with is an earlier version than Java 7 which was the target you compile your program for.
For Ubuntu use
apt-get install openjdk-7-jdk
to get Java 7 as default. You may have to uninstall openjdk-6 first.
As @AlexanderN pointed out, you can now delete App IDs.
You can just use the View.setId(integer)
for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views
you add programmatically.
According to
View
documentationThe identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.
So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

A simple comparison against string works:
<c:when test="${someModel.status == 'OLD'}">
It may be faster if you create a materialized view (with schema binding). Non-materialized views execute just like the regular query.

Another way to do it (if you use Node.js):
var input = '32343630';
const output = Buffer.from(input, 'hex');
log(input + " -> " + output); // Result: 32343630 -> 2460
For example:
you can use:
df %>% filter(!is.na(a))
to remove the NA in column a.
To select and element where you know only the attribute value you can use the below jQuery script
var src = $('.conversation_img[alt="example"]').attr('src');
Please refer the jQuery Documentation for attribute equals selectors
Please also refer to the example in Demo
Following is the code incase you are not able to access the demo..
HTML
<div>
<img alt="example" src="\images\show.jpg" />
<img alt="exampleAll" src="\images\showAll.jpg" />
</div>
SCRIPT JQUERY
var src = $('img[alt="example"]').attr('src');
alert("source of image with alternate text = example - " + src);
var srcAll = $('img[alt="exampleAll"]').attr('src');
alert("source of image with alternate text = exampleAll - " + srcAll );
Output will be
Two Alert messages each having values
updateValue(data){
// retriving index from array
let indexValue = this.items.indexOf(data);
// changing specific element in array
this.items[indexValue].isShow = !this.items[indexValue].isShow;
}
I find the following code to be much simpler than anything else:
function setCookie(name,value,days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + (value || "") + expires + "; path=/";
}
function getCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}

On some systems, the hostname is set in the environment. If that is the case for you, the os module can pull it out of the environment via os.getenv. For example, if HOSTNAME is the environment variable containing what you want, the following will get it:
import os
system_name = os.getenv('HOSTNAME')
Update: As noted in the comments, this doesn't always work, as not everyone's environment is set up this way. I believe that at the time I initially answered this I was using this solution as it was the first thing I'd found in a web search and it worked for me at the time. Due to the lack of portability I probably wouldn't use this now. However, I am leaving this answer for reference purposes. FWIW, it does eliminate the need for other imports if your environment has the system name and you are already importing the os module. Test it - if it doesn't work in all the environments in which you expect your program to operate, use one of the other solutions provided.
That's as easy as
IsNull(FieldName, 0)
Or more completely:
SELECT iar.Description,
ISNULL(iai.Quantity,0) as Quantity,
ISNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail',
iar.Compliance
FROM InventoryAdjustmentReason iar
LEFT OUTER JOIN InventoryAdjustmentItem iai on (iar.Id = iai.InventoryAdjustmentReasonId)
LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'
this is the code of your button
<a href="AddNewUserAdmin"

in the controller just add this function.
var app = angular.module('userAPP', []);

Generally speaking, float
is a relative positioning statement, since it specifies the position of the element relative to its parent container (floating to the right or left). This means it's incompatible with the position:absolute
property, because position:absolute
is an absolute positioning statement. You can either float an element and allow the browser to position it relative to its parent container, or you can specify an absolute position and force the element to appear in a certain position regardless of its parent. If you want an absolutely-positioned element to appear on the right side of the screen, you can use position: absolute; right: 0;
, but this will cause the element to always appear on the right edge of the screen regardless of how wide its parent div
is (so it won't be "at the right of its parent div").
You probably need to use a TableModel
(Oracle's tutorial here)
How implements your own TableModel
public class FootballClubTableModel extends AbstractTableModel {
private List<FootballClub> clubs ;
private String[] columns ;
public FootBallClubTableModel(List<FootballClub> aClubList){
super();
clubs = aClubList ;
columns = new String[]{"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};
}
// Number of column of your table
public int getColumnCount() {
return columns.length ;
}
// Number of row of your table
public int getRowsCount() {
return clubs.size();
}
// The object to render in a cell
public Object getValueAt(int row, int col) {
FootballClub club = clubs.get(row);
switch(col) {
case 0: return club.getPosition();
// to complete here...
default: return null;
}
}
// Optional, the name of your column
public String getColumnName(int col) {
return columns[col] ;
}
}
You maybe need to override anothers methods of TableModel
, depends on what you want to do, but here is the essential methods to understand and implements :)
Use it like this
List<FootballClub> clubs = getFootballClub();
TableModel model = new FootballClubTableModel(clubs);
JTable table = new JTable(model);
Hope it help !
When using permitAll
it means every authenticated user, however you disabled anonymous access so that won't work.
What you want is to ignore certain URLs for this override the configure
method that takes WebSecurity
object and ignore
the pattern.
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/api/v1/signup");
}
And remove that line from the HttpSecurity
part. This will tell Spring Security to ignore this URL and don't apply any filters to them.
I was having the same problem too. In my case was caused when trying to reproduce videos with a poor codification (demanded too much memory). This helped me to catch the error and request another version of the same video. https://stackoverflow.com/a/11986400/2508527
There is a plugin called show functions which lists all the function definitions in a file. It also allows you to sort the function so can search them easily.
try this
public static void main(String[] args) {
int[] series = {4,2};
series = addElement(series, 3);
series = addElement(series, 1);
}
static int[] addElement(int[] a, int e) {
a = Arrays.copyOf(a, a.length + 1);
a[a.length - 1] = e;
return a;
}
I have an answer for you Yes, It is possible.
Go to
SQL Server Management Studio > select Database > click on attach
Then select and add .mdf and .ldf file. Click on OK.
It is a string formatting syntax (which it borrows from C).
Please see "PyFormat":
Python supports formatting values into strings. Although this can include very complicated expressions, the most basic usage is to insert values into a string with the
%s
placeholder.
Edit: Here is a really simple example:
#Python2
name = raw_input("who are you? ")
print "hello %s" % (name,)
#Python3+
name = input("who are you? ")
print("hello %s" % (name,))
The %s
token allows me to insert (and potentially format) a string. Notice that the %s
token is replaced by whatever I pass to the string after the %
symbol. Notice also that I am using a tuple here as well (when you only have one string using a tuple is optional) to illustrate that multiple strings can be inserted and formatted in one statement.
I tried to push to my own hosted bonobo-git server, and did not realise, that the http.postbuffer meant the project directory ...
so just for other confused ones:
why? In my case, I had large zip files with assets and some PSDs pushed as well - to big for the buffer I guess.
How to do this http.postbuffer: execute that command within your project src directory, next to the .git folder, not on the server.
be aware, large temp (chunk) files will be created of that buffer size.
Note: Just check your largest files, then set the buffer.
I think the Vim documentation should've explained the meaning behind the naming of these commands. Just telling you what they do doesn't help you remember the names.
map
is the "root" of all recursive mapping commands. The root form applies to "normal", "visual+select", and "operator-pending" modes. (I'm using the term "root" as in linguistics.)
noremap
is the "root" of all non-recursive mapping commands. The root form applies to the same modes as map
. (Think of the nore
prefix to mean "non-recursive".)
(Note that there are also the !
modes like map!
that apply to insert & command-line.)
See below for what "recursive" means in this context.
Prepending a mode letter like n
modify the modes the mapping works in. It can choose a subset of the list of applicable modes (e.g. only "visual"), or choose other modes that map
wouldn't apply to (e.g. "insert").
Use help map-modes
will show you a few tables that explain how to control which modes the mapping applies to.
Mode letters:
n
: normal onlyv
: visual and selecto
: operator-pendingx
: visual onlys
: select onlyi
: insertc
: command-linel
: insert, command-line, regexp-search (and others. Collectively called "Lang-Arg" pseudo-mode)"Recursive" means that the mapping is expanded to a result, then the result is expanded to another result, and so on.
The expansion stops when one of these is true:
At that point, Vim's default "meaning" of the final result is applied/executed.
"Non-recursive" means the mapping is only expanded once, and that result is applied/executed.
Example:
nmap K H
nnoremap H G
nnoremap G gg
The above causes K
to expand to H
, then H
to expand to G
and stop. It stops because of the nnoremap
, which expands and stops immediately. The meaning of G
will be executed (i.e. "jump to last line"). At most one non-recursive mapping will ever be applied in an expansion chain (it would be the last expansion to happen).
The mapping of G
to gg
only applies if you press G
, but not if you press K
. This mapping doesn't affect pressing K
regardless of whether G
was mapped recursively or not, since it's line 2 that causes the expansion of K
to stop, so line 3 wouldn't be used.
In my case, Oracle TNS Service was using port 8080, found that using running the command "netstat - anob" as an administrator. Simply used Shutdown Database from the Windows start menu to stop that service and was able to start the SpringBoot app without any issue.
Also if you cannot find out which app is using the 8080 port and just want to run the SprintBoot app, you can click on Run As... and in the VM arguments enter: -Dserver.port=0 (this will pick any random available port) or you can be specific like: -Dserver.port=8081
Hope it helps.
With this query you can execute any stored procedure(With or Without output parameter):
DECLARE @temp varchar(100)
EXEC my_sp
@parameter1 = 1,
@parameter2 = 2,
@parameter3 = @temp output,
@parameter4 = 3,
@parameter5 = 4
PRINT @temp
Here datatype of @temp should be same as @parameter3 within SP.
Hope this helps..
Give Safe User Permission To Use Port 80
Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/
Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port
- where port number > 1024.
A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``
Now, when you tell a Node application that you want it to run on port 80, it will not complain.

@bku_drytt's solution didn't do it for me.
I solved it by additionally changing every occurence of 14.0
to 12.0
and v140
to v120
manually in the .vcxproj files.
Then it compiled!
@vomako 's solution almost solved my problem but I had to take another couple of steps.
I refer to the following...
In Xcode 6.1.1, I went to Preferences --> Accounts --> View Details
After upgrading to Xcode 6.1.1, the main issue for me that the >View Details button was greyed out.
I had to delete my account, restart Xcode, then add my developer account back in.
After this step, I could yet again view details and refresh my provisioning profiles.
Descending order using underscore can be done by multiplying the return value by -1.
//Ascending Order:
_.sortBy([2, 3, 1], function(num){
return num;
}); // [1, 2, 3]
//Descending Order:
_.sortBy([2, 3, 1], function(num){
return num * -1;
}); // [3, 2, 1]
If you're sorting by strings not numbers, you can use the charCodeAt() method to get the unicode value.
//Descending Order Strings:
_.sortBy(['a', 'b', 'c'], function(s){
return s.charCodeAt() * -1;
});

This solution mostly relies on TimestampType implementation with adding additional behaviour through anonymous class of type JdbcTimestampTypeDescriptor.
Try this simple function to add an dictionary item if it does not exist or update when it exists:
public void AddOrUpdateDictionaryEntry(string key, int value)
{
if (dict.ContainsKey(key))
{
dict[key] = value;
}
else
{
dict.Add(key, value);
}
}
This is the same as dict[key] = value.
Be aware that the new version (5) of font awesome uses "fas"
or "fab"
instead of "fa"
prefix.
Quoted from their website:
The fa prefix has been deprecated in version 5. The new default is the fas solid style and the fab style for brands.
This is why my fonts were showing blank squares. Now fixed.
Example code:
<a class="nav-link" href="//www.facebook.com/xxx" target="_blank"><i class="fab fa-facebook-f"></i></a>
Its a very old thread, but I don't see that the solution is here or the this thread is marked as solved. I have also stuck into the same problem I solved it like this
$path = public_path('../storage/YOUR_FOLDER_NAME/YOUR_FILE_NAME');
if (!File::exists($path))
{
File::delete(public_path('storage/YOUR_FOLDER_NAME/YOUR_FILE_NAME'));
}
The key is that you need to remove '..' from the delete method. Keep in mind that this goes true if you are using Storage as well, whether you are using Storage of File don't for get to use them like
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use File; // For File
use Storage; // For Storage
Hope that it will help someone.
A Swift 3 solution using an extension. Ideal if you have several numeric UITextField
objects in your app as it gives the flexibility to decide, for each UITextField
, whether to perform a custom action when Done or Cancel is tapped.
//
// UITextField+DoneCancelToolbar.swift
//
import UIKit
extension UITextField {
func addDoneCancelToolbar(onDone: (target: Any, action: Selector)? = nil, onCancel: (target: Any, action: Selector)? = nil) {
let onCancel = onCancel ?? (target: self, action: #selector(cancelButtonTapped))
let onDone = onDone ?? (target: self, action: #selector(doneButtonTapped))
let toolbar: UIToolbar = UIToolbar()
toolbar.barStyle = .default
toolbar.items = [
UIBarButtonItem(title: "Cancel", style: .plain, target: onCancel.target, action: onCancel.action),
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: self, action: nil),
UIBarButtonItem(title: "Done", style: .done, target: onDone.target, action: onDone.action)
]
toolbar.sizeToFit()
self.inputAccessoryView = toolbar
}
// Default actions:
func doneButtonTapped() { self.resignFirstResponder() }
func cancelButtonTapped() { self.resignFirstResponder() }
}
Example of usage using the default actions:
//
// MyViewController.swift
//
@IBOutlet weak var myNumericTextField: UITextField! {
didSet { myNumericTextField?.addDoneCancelToolbar() }
}
Example of usage using a custom Done action:
//
// MyViewController.swift
//
@IBOutlet weak var myNumericTextField: UITextField! {
didSet {
myNumericTextField?.addDoneCancelToolbar(onDone: (target: self, action: #selector(doneButtonTappedForMyNumericTextField)))
}
}
func doneButtonTappedForMyNumericTextField() {
print("Done");
myNumericTextField.resignFirstResponder()
}
You should use Root
to refer to the root element:
xmlFile.Root.Elements("Band")
If you want to find elements anywhere in the document use Descendants
instead:
xmlFile.Descendants("Band")
To avoid a global install, add Nodemon as a dependency, then...
package.json
"scripts": {
"start": "node ./bin/www",
"start-dev": "./node_modules/nodemon/bin/nodemon.js ./bin/www"
},
you can use the below command for reset of single file
git checkout HEAD -- path_to_file/file_name
List all changed files to get path_to_file/filename
with below command
git status
private void Fetching_Record_Grid_MouseDoubleClick_1(object sender, MouseButtonEventArgs e)
{
IInputElement element = e.MouseDevice.DirectlyOver;
if (element != null && element is FrameworkElement)
{
if (((FrameworkElement)element).Parent is DataGridCell)
{
var grid = sender as DataGrid;
if (grid != null && grid.SelectedItems != null && grid.SelectedItems.Count == 1)
{
//var rowView = grid.SelectedItem as DataRowView;
try
{
Station station = (Station)grid.SelectedItem;
id_txt.Text = station.StationID.Trim() ;
description_txt.Text = station.Description.Trim();
}
catch
{
}
}
}
}
}
If this helps you,
<input type="checkbox" (ngModelChange)="mychange($event)" [ngModel]="mymodel">
mychange(val)
{
console.log(val); // updated value
}
If your question about <input type="date">
field, here is script for getting filed value=""
attribute:
(new Date()).toISOString().split('T')[0]
You can use the Intl object (ecma-402) to get data-date-pattern=""
:
(new Intl.DateTimeFormat()).resolved.pattern // "M/d/y" for "en-US" in Google Chrome
And finnaly, to format date in current l10n, data-date=""
:
(new Intl.DateTimeFormat()).format(new Date());

int max = 50;
int min = 1;
double random = Math.random() * 49 + 1;
or
int random = (int )(Math.random() * 50 + 1);
This will give you value from 1 to 50 in case of int or 1.0 (inclusive) to 50.0 (exclusive) in case of double
Why?
random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches.
Random rand = new Random();
int value = rand.nextInt(50);
This will give value from 0 to 49.
For 1 to 50: rand.nextInt((max - min) + 1) + min;

Below are the complete changes I needed to make to run my x64 bit IIS application using IIS Express, so that it was accessible to a remote host:
iisexpress /config:"C:\Users\test-user\Documents\IISExpress\config\applicationhost.config" /site:MyWebSite
Starting IIS Express ...
Successfully registered URL "http://192.168.2.133:8080/" for site "MyWebSite" application "/"
Registration completed for site "MyWebSite"
IIS Express is running.
Enter 'Q' to stop IIS Express
The configuration file (applicationhost.config) had a section added as follows:
<sites>
<site name="MyWebsite" id="2">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\build\trunk\MyWebsite" />
</application>
<bindings>
<binding protocol="http" bindingInformation=":8080:192.168.2.133" />
</bindings>
</site>
The 64 bit version of the .NET framework can be enabled as follows:
<globalModules>
<!--
<add name="ManagedEngine" image="%windir%\Microsoft.NET\Framework\v2.0.50727\webengine.dll" preCondition="integratedMode,runtimeVersionv2.0,bitness32" />

You can use d6tstack which creates the table for you and is faster than pd.to_sql() because it uses native DB import commands. It supports Postgres as well as MYSQL and MS SQL.
import pandas as pd
df = pd.read_csv('table.csv')
uri_psql = 'postgresql+psycopg2://usr:pwd@localhost/db'
d6tstack.utils.pd_to_psql(df, uri_psql, 'table')
It is also useful for importing multiple CSVs, solving data schema changes and/or preprocess with pandas (eg for dates) before writing to db, see further down in examples notebook
d6tstack.combine_csv.CombinerCSV(glob.glob('*.csv'),
apply_after_read=apply_fun).to_psql_combine(uri_psql, 'table')
May do simple for loop with checking types:
with open("jsondontdoit.json", 'w') as fp:
for key in bests.keys():
if type(bests[key]) == np.ndarray:
bests[key] = bests[key].tolist()
continue
for idx in bests[key]:
if type(bests[key][idx]) == np.ndarray:
bests[key][idx] = bests[key][idx].tolist()
json.dump(bests, fp)
fp.close()
Regex is not on the list of search features, and it was on (more or less, as Better message search functionality (i.e. Wildcard and partial word search)) the list of pre-canned feature requests, so the answer is "you cannot do this via the Gmail web UI" :-(
There are no current Labs features which offer this. SIEVE filters would be another way to do this, that too was not supported, there seems to no longer be any definitive statement on SIEVE support in the Gmail help.
Updated for link rot The pre-canned list of feature requests was, er canned, the original is on archive.org dated 2012, now you just get redirected to a dumbed down page telling you how to give feedback. Lack of SIEVE support was covered in answer 78761 Does Gmail support all IMAP features?, since some time in 2015 that answer silently redirects to the answer about IMAP client configuration, archive.org has a copy dated 2014.
With the current search facility brackets of any form () {} []
are used for grouping, they have no observable effect if there's just one term within. Using (aaa|bbb)
and [aaa|bbb]
are equivalent and will both find words aaa
or bbb
. Most other punctuation characters, including \
, are treated as a space or a word-separator, +
-
:
and "
do have special meaning though, see the help.
As of 2016, only the form "{term1 term2}
" is documented for this, and is equivalent to the search "term1 OR term2
".
You can do regex searches on your mailbox (within limits) programmatically via Google docs: http://www.labnol.org/internet/advanced-gmail-search/21623/ has source showing how it can be done (copy the document, then Tools > Script Editor
to get the complete source).
You could also do this via IMAP as described here: Python IMAP search for partial subject and script something to move messages to different folder. The IMAP SEARCH verb only supports substrings, not regex (Gmail search is further limited to complete words, not substrings), further processing of the matches to apply a regex would be needed.
For completeness, one last workaround is: Gmail supports plus addressing, if you can change the destination address to [email protected]
it will still be sent to your mailbox where you can filter by recipient address. Make sure to filter using the full email address to:[email protected]
. This is of course more or less the same thing as setting up a dedicated Gmail address for this purpose :-)
Try
\d \w |\d
or add a positive lookahead if you don't want to include the trailing space in the match
\d \w(?= )|\d
When you have two alternatives where one is an extension of the other, put the longer one first, otherwise it will have no opportunity to be matched.
Try removing "package-lock.json" and running "npm install && npm update", it'll install the latest version and clear all errors.
Dump extensions:
code --list-extensions > extensions.txt
Install extensions with Bash (Linux, OS X and WSL):
cat extensions.txt | xargs code --list-extensions {}
Install extensions on Windows with PowerShell:
cat extensions.txt |% { code --install-extension $_}
You cannot use <li href="#"
since it belongs to <a href="#"
that's why it wasn't working, change it and it's all good.
Here is working JSFiddle which shows you how to create bootstrap popover.
Relevant parts of the code is below:
HTML:
<!--
Note: Popover content is read from "data-content" and "title" tags.
-->
<a tabindex="0"
class="btn btn-lg btn-primary"
role="button"
data-html="true"
data-toggle="popover"
data-trigger="focus"
title="<b>Example popover</b> - title"
data-content="<div><b>Example popover</b> - content</div>">Example popover</a>
JavaScript:
$(function(){
// Enables popover
$("[data-toggle=popover]").popover();
});
And by the way, you always need at least $("[data-toggle=popover]").popover();
to enable the popover. But in place of data-toggle="popover"
you can also use id="my-popover"
or class="my-popover"
. Just remember to enable them using e.g: $("#my-popover").popover();
in those cases.
Here is the link to the complete spec: Bootstrap Popover
Bonus:
If for some reason you don't like or cannot read content of a popup from the data-content
and title
tags. You can also use e.g. hidden divs and a bit more JavaScript. Here is an example about that.
First off, RangeToHTML
. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.
On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.
For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

MsgBox "The selection is not a range or the sheet is protected. " & _
vbNewLine & "Please correct and try again.", vbOKOnly
Exit Sub
End If

.EnableEvents = False
.ScreenUpdating = False

You can use custom validation:
[CustomValidation(typeof(ValidationMethods), "ValidateGreaterOrEqualToZero")]
public int IntValue { get; set; }
[CustomValidation(typeof(ValidationMethods), "ValidateGreaterOrEqualToZero")]
public decimal DecValue { get; set; }
Validation methods type:
public class ValidationMethods
{
public static ValidationResult ValidateGreaterOrEqualToZero(decimal value, ValidationContext context)
{
bool isValid = true;
if (value < decimal.Zero)
{
isValid = false;
}
if (isValid)
{
return ValidationResult.Success;
}
else
{
return new ValidationResult(
string.Format("The field {0} must be greater than or equal to 0.", context.MemberName),
new List<string>() { context.MemberName });
}
}
}
A Scala version based on Zaz's answer.
case class DocumentEx(document: Document) {
def toXmlString(pretty: Boolean = false):Try[String] = {
getStringFromDocument(document, pretty)
}
}
implicit def documentToDocumentEx(document: Document):DocumentEx = {
DocumentEx(document)
}
def getStringFromDocument(doc: Document, pretty:Boolean): Try[String] = {
try
{
val domSource= new DOMSource(doc)
val writer = new StringWriter()
val result = new StreamResult(writer)
val tf = TransformerFactory.newInstance()
val transformer = tf.newTransformer()
if (pretty)
transformer.setOutputProperty(OutputKeys.INDENT, "yes")
transformer.transform(domSource, result)
Success(writer.toString);
}
catch {
case ex: TransformerException =>
Failure(ex)
}
}
With that, you can do either doc.toXmlString()
or call the getStringFromDocument(doc)
function.
Forgot to relate to the first code snippet. I wouldn't use forEach
at all. Since you are collecting the elements of the Stream
into a List
, it would make more sense to end the Stream
processing with collect
. Then you would need peek
in order to set the ID.
List<Entry> updatedEntries =
entryList.stream()
.peek(e -> e.setTempId(tempId))
.collect (Collectors.toList());
For the second snippet, forEach
can execute multiple expressions, just like any lambda expression can :
entryList.forEach(entry -> {
if(entry.getA() == null){
printA();
}
if(entry.getB() == null){
printB();
}
if(entry.getC() == null){
printC();
}
});
However (looking at your commented attempt), you can't use filter in this scenario, since you will only process some of the entries (for example, the entries for which entry.getA() == null
) if you do.
More methods in java 8:
EnumSet
with forEach
EnumSet.allOf(Direction.class).forEach(...);
Arrays.asList
with forEach
Arrays.asList(Direction.values()).forEach(...);
sc queryex <service name>
taskkill /F /PID <Service PID>
eg
Locate where your keytool.exe inside java installation folder
mine is
C:\Program Files\Java\jre1.8.0_181\bin
open cmd anywhere and run
SET PATH=%PATH%;C:\Program Files\Java\jre1.8.0_181\bin;
change the path to the path you located your keytool.exe
Since youre using JSON, I would Base64 Encode it before sending it across the wire.
If the files are large, try to look at BSON, or some other format that is better with binary transfers.
You could also zip the files, if they compress well, before base64 encoding them.
Here's a one-liner for using React Router to redirect to an external link:
<Route path='/privacy-policy' component={() => {
window.location.href = 'https://example.com/1234';
return null;
}}/>
It uses React pure component concept to reduce the component's code to a single function that, instead of rendering anything, redirects browser to an external URL.
Works both on React Router 3 and 4.
The request body is available as byte stream by HttpServletRequest#getInputStream()
:
InputStream body = request.getInputStream();
// ...
Or as character stream by HttpServletRequest#getReader()
:
Reader body = request.getReader();
// ...
Note that you can read it only once. The client ain't going to resend the same request multiple times. Calling getParameter()
and so on will implicitly also read it. If you need to break down parameters later on, you've got to store the body somewhere and process yourself.
I think a bit of code will help illustrate what setters and getters are:
public class Foo
{
private string bar;
public string GetBar()
{
return bar;
}
public void SetBar(string value)
{
bar = value;
}
}
In this example we have a private member of the class that is called bar. The GetBar and SetBar methods do exactly what they are named - one retrieves the bar member, and the other sets its value.
In c# 1.1 + you have properties. The basic functionality is also the same:
public class Foo
{
private string bar;
public string Bar
{
get { return bar; }
set { bar = value; }
}
}
The private member bar is not accessible outside the class. However the public "Bar" is, and it has two accessors - get, which just as the example above "GetBar()" returns the private member, and also a set - which corresponds to the SetBar(string value) method in the forementioned example.
Starting with C# 3.0 and above the compiler became optimized to the point where such properties do not need to have the private member as their source. The compiler automatically generates a private member of that type and uses it as a source of a property.
public class Foo
{
public string Bar { get; set; }
}
what the code shows is an automatic property that has a private member generated by the compiler. You don't see the private member but it is there. This also introduced a couple of other issues - mainly with access control. In C# 1.1, and 2.0 you could omit the get or set portion of a property:
public class Foo
{
private string bar;
public string Bar
{
get{ return bar; }
}
}
Giving you the chance to restrict how other objects interact with the "Bar" property of the Foo class. Starting with C# 3.0 and above - if you chose to use automatic properties you would have to specify the access to the property as follows:
public class Foo
{
public string Bar { get; private set; }
}
What that means is that only the class itself can set Bar to some value, however anyone could read the value in Bar.
I have a test application set up using JPA/Hibernate & Spring, and my configuration mirrors yours with the exception that I create a datasource and inject it into the EntityManagerFactory, and moved the datasource specific properties out of the persistenceUnit and into the datasource. With these two small changes, my EM gets injected properly.
You can find the info here: http://www.php.net/manual/en/language.operators.comparison.php
It's scarce because it wasn't added until PHP4. What you have is fine though, if you know there may be a type difference then it's a much better comparison, since it's testing value and type in the comparison, not just value.
You can use join
with pop
+ tolist
. Performance is comparable to concat
with drop
+ tolist
, but some may find this syntax cleaner:
res = df.join(pd.DataFrame(df.pop('b').tolist()))
Benchmarking with other methods:
df = pd.DataFrame({'a':[1,2,3], 'b':[{'c':1}, {'d':3}, {'c':5, 'd':6}]})
def joris1(df):
return pd.concat([df.drop('b', axis=1), df['b'].apply(pd.Series)], axis=1)
def joris2(df):
return pd.concat([df.drop('b', axis=1), pd.DataFrame(df['b'].tolist())], axis=1)
def jpp(df):
return df.join(pd.DataFrame(df.pop('b').tolist()))
df = pd.concat([df]*1000, ignore_index=True)
%timeit joris1(df.copy()) # 1.33 s per loop
%timeit joris2(df.copy()) # 7.42 ms per loop
%timeit jpp(df.copy()) # 7.68 ms per loop
git push --dry-run
git diff --stat HEAD remote/branch
var data = [
{"Id": 10004, "PageName": "club"},
{"Id": 10040, "PageName": "qaz"},
{"Id": 10059, "PageName": "jjjjjjj"}
];
$.each(data, function(i, item) {
alert(data[i].PageName);
});
$.each(data, function(i, item) {
alert(item.PageName);
});
these two options work well, unless you have something like:
var data.result = [
{"Id": 10004, "PageName": "club"},
{"Id": 10040, "PageName": "qaz"},
{"Id": 10059, "PageName": "jjjjjjj"}
];
$.each(data.result, function(i, item) {
alert(data.result[i].PageName);
});
EDIT:
try with this and describes what the result
$.get('/Cms/GetPages/123', function(data) {
alert(data);
});
FOR EDIT 3:
this corrects the problem, but not the idea to use "eval", you should see how are the response in '/Cms/GetPages/123'.
$.get('/Cms/GetPages/123', function(data) {
$.each(eval(data.replace(/[\r\n]/, "")), function(i, item) {
alert(item.PageName);
});
});
If none of the above works try this. This is what I did in MYSQL and yes, you need to write the column name (document_id) twice.
ALTER TABLE document
CHANGE COLUMN document_id document_id INT(11) NOT NULL AUTO_INCREMENT ;
select 'one'||'&'||'two' from dual
I was having the same problem. None of the above solutions worked for me. The key challenge was that I didn't have the root access. So, I first download the source of libffi. Then I compiled it with usual commands:
./configure --prefix=desired_installation_path_to_libffi
make
Then I recompiled python using
./configure --prefix=/home/user123/Softwares/Python/installation3/ LDFLAGS='-L/home/user123/Softwares/library/libffi/installation/lib64'
make
make install
In my case, 'home/user123/Softwares/library/libffi/installation/lib64' is path to LIBFFI installation directory where libffi.so is located. And, /home/user123/Softwares/Python/installation3/ is path to Python installation directory. Modify them as per your case.

I suspect you are running Android 6.0 Marshmallow (API 23) or later. If this is the case, you must implement runtime permissions before you try to read/write external storage.
Try
#include <inttypes.h>
...
printf("i [ %zu ] k [ %"PRIu32" ]\n", i, k);
The z
represents an integer of length same as size_t
, and the PRIu32
macro, defined in the C99 header inttypes.h
, represents an unsigned 32-bit integer.
This code may be helpful for you.

It is good practice when you start creating website to reset all the margins and paddings. So I recommend on start just to simple do:
* { margin: 0, padding: 0 }
This will make margins and paddings of all elements to be 0, and then you can style them as you wish, because each browser has a different default margin and padding of the elements.
@Senthil and @Arend answer (https://stackoverflow.com/a/5711150/2268559) mentioned ProcessBuilder
. Here is the example using ProcessBuilder
with specifying environment variables and working folder for the command:
ProcessBuilder pb = new ProcessBuilder("ls", "-a", "-l");
Map<String, String> env = pb.environment();
// If you want clean environment, call env.clear() first
//env.clear();
env.put("VAR1", "myValue");
env.remove("OTHERVAR");
env.put("VAR2", env.get("VAR1") + "suffix");
File workingFolder = new File("/home/user");
pb.directory(workingFolder);
Process proc = pb.start();
BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));
// Read the output from the command:
System.out.println("Here is the standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null)
System.out.println(s);
// Read any errors from the attempted command:
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null)
System.out.println(s);
Change the access modifier of
counter
topublic volatile
As other people have mentioned, this on its own isn't actually safe at all. The point of volatile
is that multiple threads running on multiple CPUs can and will cache data and re-order instructions.
If it is not volatile
, and CPU A increments a value, then CPU B may not actually see that incremented value until some time later, which may cause problems.
If it is volatile
, this just ensures the two CPUs see the same data at the same time. It doesn't stop them at all from interleaving their reads and write operations which is the problem you are trying to avoid.
lock(this.locker) this.counter++
;
This is safe to do (provided you remember to lock
everywhere else that you access this.counter
). It prevents any other threads from executing any other code which is guarded by locker
.
Using locks also, prevents the multi-CPU reordering problems as above, which is great.
The problem is, locking is slow, and if you re-use the locker
in some other place which is not really related then you can end up blocking your other threads for no reason.
Interlocked.Increment(ref this.counter);
This is safe, as it effectively does the read, increment, and write in 'one hit' which can't be interrupted. Because of this, it won't affect any other code, and you don't need to remember to lock elsewhere either. It's also very fast (as MSDN says, on modern CPUs, this is often literally a single CPU instruction).
I'm not entirely sure however if it gets around other CPUs reordering things, or if you also need to combine volatile with the increment.
InterlockedNotes:
As volatile
doesn't prevent these kinds of multithreading issues, what's it for? A good example is saying you have two threads, one which always writes to a variable (say queueLength
), and one which always reads from that same variable.
If queueLength
is not volatile, thread A may write five times, but thread B may see those writes as being delayed (or even potentially in the wrong order).
A solution would be to lock, but you could also use volatile in this situation. This would ensure that thread B will always see the most up-to-date thing that thread A has written. Note however that this logic only works if you have writers who never read, and readers who never write, and if the thing you're writing is an atomic value. As soon as you do a single read-modify-write, you need to go to Interlocked operations or use a Lock.
If anyone is interested, you can have the the offset information for all the consumer groups with the following command:
kafka-consumer-groups --bootstrap-server localhost:9092 --all-groups --describe
The parameter --all-groups is available from Kafka 2.4.0

Pyhton3: Most of the solutions listed previously work. However, there are instances when row_number of the dataframe is not required and the each row (record) has to be written individually.
The following method is useful in that case.
import csv
my file= 'C:\Users\John\Desktop\export_dataframe.csv'
records_to_save = data2 #used as in the thread.
colnames = list[records_to_save[0].keys()]
# remember colnames is a list of all keys. All values are written corresponding
# to the keys and "None" is specified in case of missing value
with open(myfile, 'w', newline="",encoding="utf-8") as f:
writer = csv.writer(f)
writer.writerow(colnames)
for d in records_to_save:
writer.writerow([d.get(r, "None") for r in colnames])
If you don't want anything to display before the redirect, then you will need to use some server side scripting to accomplish the task before the page is served. The page has already begun loading by the time your Javascript is executed on the client side.
If Javascript is your only option, your best best is to make your script the first .js file included in the <head>
of your document.
Instead of Javascript, I recommend setting up your redirect logic in your Apache or nginx server configuration.
Here's an example from AndroidManifest.xml. You need to specify the MAIN and LAUNCHER in the intent filter for the activity you want to start on launch
<application android:label="@string/app_name" android:icon="@drawable/icon">
<activity android:name="ExampleActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
import types
import yourmodule
print([getattr(yourmodule, a) for a in dir(yourmodule)
if isinstance(getattr(yourmodule, a), types.FunctionType)])
in laravel 5 first we need to create migration and then run the migration
Step 1.
php artisan make:migration create_users_table --create=users
Step 2.
php artisan migrate
I would use compileall. It works nicely both from scripts and from the command line. It's a bit higher level module/tool than the already mentioned py_compile that it also uses internally.
ALTER TABLE tablename add newcolumn int
update tablename set newcolumn=existingcolumnname
ALTER TABLE tablename DROP COLUMN existingcolumnname;
EXEC sp_RENAME 'tablename.oldcolumn' , 'newcolumnname', 'COLUMN'
update tablename set newcolumnname=value where condition
However above code works only if there is no primary-foreign key relation
Are you missing a using directive for System.Linq

That would be an HTML Encoded Line Feed character (using the hexadecimal value).

std::unique_ptr has no copy constructor. You create an instance and then ask the std::vector to copy that instance during initialisation.
error: deleted function 'std::unique_ptr<_Tp, _Tp_Deleter>::uniqu
e_ptr(const std::unique_ptr<_Tp, _Tp_Deleter>&) [with _Tp = int, _Tp_D
eleter = std::default_delete<int>, std::unique_ptr<_Tp, _Tp_Deleter> =
std::unique_ptr<int>]'
The class satisfies the requirements of MoveConstructible and MoveAssignable, but not the requirements of either CopyConstructible or CopyAssignable.
The following works with the new emplace calls.
std::vector< std::unique_ptr< int > > vec;
vec.emplace_back( new int( 1984 ) );
See using unique_ptr with standard library containers for further reading.
The string
class's Replace
method can also be used to remove multiple characters from a string:
Dim newstring As String
newstring = oldstring.Replace(",", "").Replace(";", "")
Assuming that you have a DHCP server running at your router I would use:
# /etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
After changing the file issue (as root):
/etc/init.d/networking restart
Along with the already suggested methods of using a foreach
loop, I thought I'd also mention that any object that implements IEnumerable
also provides an IEnumerator
interface via the GetEnumerator
method. Although this method is usually not necessary, this can be used for manually iterating over collections, and is particularly useful when writing your own extension methods for collections.
IEnumerable<T> mySequence;
using (var sequenceEnum = mySequence.GetEnumerator())
{
while (sequenceEnum.MoveNext())
{
// Do something with sequenceEnum.Current.
}
}
A prime example is when you want to iterate over two sequences concurrently, which is not possible with a foreach
loop.
Just use this line
svn update -r yourOldRevesion
You can know your current revision by using:
svn info
i have just added (overflow:scroll;) in (div3) with fixed height.
see the fiddle:- http://jsfiddle.net/fMs67/10/
if you are in a activity, assume there is only one root view,you can get it like this.
ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this
.findViewById(android.R.id.content)).getChildAt(0);
you can then cast it to your real class
or you could using
getWindow().getDecorView();
notice this will include the actionbar view, your view is below the actionbar view
Im not very familiar with the Android sdk, but it seems that the android-sdk
comes with the BouncyCastle
provider already added to the security.
What you will have to do in the PC environment is just add it manually,
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
if you have access to the policy
file, just add an entry like:
security.provider.5=org.bouncycastle.jce.provider.BouncyCastleProvider
Notice the .5
it is equal to a sequential number of the already added providers.
If you have downloaded the latest Version 4.3.4 then just follow these steps.
Load the mentioned js file
<script type="text/javascript" src="/ckeditor/ckeditor.js"></script> <textarea class="ckeditor" name="editor"></textarea>
Other answers to this question do not return what the OP needs, they will return a string like:
test1 test2 test3 test1 test3 test4
(notice that test1
and test3
are duplicated) while the OP wants to return this string:
test1 test2 test3 test4
the problem here is that the string "test1 test3"
is duplicated and is inserted only once, but all of the others are distinct to each other ("test1 test2 test3"
is distinct than "test1 test3"
, even if some tests contained in the whole string are duplicated).
What we need to do here is to split each string into different rows, and we first need to create a numbers table:
CREATE TABLE numbers (n INT);
INSERT INTO numbers VALUES
(1),(2),(3),(4),(5),(6),(7),(8),(9),(10);
then we can run this query:
SELECT
SUBSTRING_INDEX(
SUBSTRING_INDEX(tableName.categories, ' ', numbers.n),
' ',
-1) category
FROM
numbers INNER JOIN tableName
ON
LENGTH(tableName.categories)>=
LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1;
and we get a result like this:
test1
test4
test1
test1
test2
test3
test3
test3
and then we can apply GROUP_CONCAT aggregate function, using DISTINCT clause:
SELECT
GROUP_CONCAT(DISTINCT category ORDER BY category SEPARATOR ' ')
FROM (
SELECT
SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
FROM
numbers INNER JOIN tableName
ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
) s;
Please see fiddle here.
Keep the h2 at the top, then pull-left on the p and pull-right on the login-box
<div class='container'>
<div class='hero-unit'>
<h2>Welcome</h2>
<div class="pull-left">
<p>Please log in</p>
</div>
<div id='login-box' class='pull-right control-group'>
<div class='clearfix'>
<input type='text' placeholder='Username' />
</div>
<div class='clearfix'>
<input type='password' placeholder='Password' />
</div>
<button type='button' class='btn btn-primary'>Log in</button>
</div>
<div class="clearfix"></div>
</div>
</div>
the default vertical-align on floated boxes is baseline, so the "Please log in" exactly lines up with the "Username" (check by changing the pull-right to pull-left).

Typically you need to do 5 things to include a library in your project:
1) Add #include statements necessary files with declarations/interfaces, e.g.:
#include "library.h"
2) Add an include directory for the compiler to look into
-> Configuration Properties/VC++ Directories/Include Directories (click and edit, add a new entry)
3) Add a library directory for *.lib files:
-> project(on top bar)/properties/Configuration Properties/VC++ Directories/Library Directories (click and edit, add a new entry)
4) Link the lib's *.lib files
-> Configuration Properties/Linker/Input/Additional Dependencies (e.g.: library.lib;
5) Place *.dll files either:
-> in the directory you'll be opening your final executable from or into Windows/system32
curl probably does have some options for showing more information but for things like this I always use openssl s_client
With the -debug
option this gives lots of useful information
Maybe I should add that this also works with non HTTP connections. So if you are doing "https", try the curl commands suggested below. If you aren't or want a second option openssl s_client
might be good

I was having this issue on OS X and it seemed to be caused by a version mismatch between my globally installed webpack

. Updating both to the latest version got rid of the issue.
Sometimes a lot of troubles with it. In attribute value of datapicker data is 28-06-2014, but datepicker is show or today or nothing. I decided it in a such way:
<input type="text" class="form-control datepicker" data-value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" />
I added to the input of datapicker attribute data-value, because if call jQuery(this).val() OR jQuery(this).attr('value') - nothing works. I decided init in cycle each datapicker and take its value from attribute data-value:
$("form .datepicker").each(function() {
var time = jQuery(this).data('value');
time = time.split('-');
$(this).datepicker('setDate', new Date(time[2], time[1], time[0], 0, 0, 0));
});
and it is works fine =)
You can add a launch screen file that appears to work for multiple screen sizes. I just added the MainStoryboard as a launch screen file and that stopped the app from scaling. I think I will need to add a permanent launch screen later, but that got the native resolution up and working quickly. In Xcode, go to your target, general and add the launch screen file there.
Yes, it's possible. for example checkout:
<div class="singleMatch" ng-if="match.date | date:'ddMMyyyy' === main.date && match.team1.code === main.team1code && match.team2.code === main.team2code">
//Do something here
</div>
For Visual Studio Code (Not Visual Studio) do Ctrl+Shift+P
Type Debugger for Chrome in the search bar, install it and enable it.
In your launch.json
file add this config :
{
"version": "0.1.0",
"configurations": [
{
"name": "Launch localhost with sourcemaps",
"type": "chrome",
"request": "launch",
"url": "http://localhost/mypage.html",
"webRoot": "${workspaceRoot}/app/files",
"sourceMaps": true
},
{
"name": "Launch index.html (without sourcemaps)",
"type": "chrome",
"request": "launch",
"file": "${workspaceRoot}/index.html"
},
]
}
You must launch Chrome with remote debugging enabled in order for the extension to attach to it.
Right click the Chrome shortcut, and select properties In the "target" field, append --remote-debugging-port=9222 Or in a command prompt, execute /chrome.exe --remote-debugging-port=9222
In a terminal, execute /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222
In a terminal, launch google-chrome --remote-debugging-port=9222
The best way to do that is Html without substring your text and fully dynamique For example :
public static String getTextSize(String text,int size) {
return "<span style=\"size:"+size+"\" >"+text+"</span>";
}
and you can use color attribut etc... if the other hand :
size.setText(Html.fromHtml(getTextSize(ls.numProducts,100) + " " + mContext.getString(R.string.products));
Read about the super keyword (Scroll down the Subclass Constructors). If I understand your question, you probably want to call a superclass constructor?
It is worth noting that the Java compiler will automatically put in a no-arg constructor call to the superclass if you do not explicitly invoke a superclass constructor.
https://github.com/robertleeplummerjr/wiretap.js
new Wiretap({
add: function() {
//fire when an event is bound to element
},
before: function() {
//fire just before an event executes, arguments are automatic
},
after: function() {
//fire just after an event executes, arguments are automatic
}
});
you can try:
services:

container_name: hi_my
build: .
image: hi_my_nameis:v1.0.0
1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib
Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.I solved this error "Compilation failed to see the compiler error output for details"
The solution is very Simple: Add in a Gradle below a line of code
implementation 'com.google.android.gms:play-services-ads:15.0.0'
You can get entire post body into a POJO. Following is something similar
@RequestMapping(
value = { "/api/pojo/edit" },
method = RequestMethod.POST,
produces = "application/json",
consumes = ["application/json"])
@ResponseBody
public Boolean editWinner( @RequestBody Pojo pojo) {
Where each field in Pojo (Including getter/setters) should match the Json request object that the controller receives..
Based on (dangerouslySetInnerHTML).
It's a prop that does exactly what you want. However they name it to convey that it should be use with caution
You can use the beforeSend
callback to set additional parameters (The XMLHTTPRequest
object is passed to it as its only parameter).
Just so you know, this type of cross-domain request will not work in a normal site scenario and not with any other browser. I don't even know what security limitations FF 3.5 imposes as well, just so you don't beat your head against the wall for nothing:
$.ajax({
url: 'http://bar.other',
data: { whatever:'cool' },
type: 'GET',
beforeSend: function(xhr){
xhr.withCredentials = true;
}
});
One more thing to beware of, is that jQuery is setup to normalize browser differences. You may find that further limitations are imposed by the jQuery library that prohibit this type of functionality.
Like "VB's On Error Resume Next?" That sounds kind of scary. First recommendation is don't do it. Second recommendation is don't do it and don't think about it. You need to isolate your faults better. As to how to approach this problem, it depends on how you're code is structured. If you are using a pattern like MVC or the like then this shouldn't be too difficult and would definitely not require a global exception swallower. Secondly, look for a good logging library like log4net or use tracing. We'd need to know more details like what kinds of exceptions you're talking about and what parts of your application may result in exceptions being thrown.
Jenkins uses Cron format on scheduling. You can refer this link for more detailhttps://en.wikipedia.org/wiki/Cron. One more thing, Jenkins provide us a very useful preview. Please take a look on the screenshot.
I hope this help. Thanks
I prefer this way so I don't need to remember any rare parameters.
git merge branch_name
It will then say your branch is ahead by "#
" commits, you can now pop these commits off and put them into the working changes with the following:
git reset @~#
For example if after the merge it is 1 commit ahead, use:
git reset @~1
Note: On Windows, quotes are needed. (As Josh noted in comments) eg:
git reset "@~1"
When I got an error saying "archive for required library could not be read," I solved it by removing the JARS in question from the Build Path of the project, and then using "Add External Jars" to add them back in again (navigating to the same folder that they were in). Using the "Add Jars" button wouldn't work, and the error would still be there. But using "Add External Jars" worked.
To add my own brick to the wall.
So I usually go like this:
// myproject/src/example.cpp
#include "myproject/example.h"
#include <algorithm>
#include <set>
#include <vector>
#include <3rdparty/foo.h>
#include <3rdparty/bar.h>
#include "myproject/another.h"
#include "myproject/specific/bla.h"
#include "detail/impl.h"
Each group separated by a blank line from the next one:
Also note that, apart from system headers, each file is in a folder with the name of its namespace, just because it's easier to track them down this way.
i have been working on a dropdown replacement jquery plugin to combat this problem. As of this post, it is almost indistinguishable from a native dropdown in terms of look and functionality.
here is a demo (also a link to downloads): http://programmingdrunk.com/current-projects/dropdownReplacement/
here is the project page of the plugin:
http://plugins.jquery.com/project/dropdownreplacement
(update:) the jquery plugin page seems to no longer work. I will probably not put my plugin on their new site when they get it working, so feel free to use the programmingdrunk.com link for demo/download
import re
re.sub(' ','','strip my spaces')
In Java just use the instanceof operator. This will also take care of subclasses.
ArrayList<Object> listOfObjects = new ArrayList<Object>();
for(Object obj: listOfObjects){
if(obj instanceof String){
}else if(obj instanceof Integer){
}etc...
}
You can loop through the columns collection of the datatable.
VB
Dim dt As New DataTable()
For Each column As DataColumn In dt.Columns
Console.WriteLine(column.ColumnName)
Next
C#
DataTable dt = new DataTable();
foreach (DataColumn column in dt.Columns)
{
Console.WriteLine(column.ColumnName);
}
Hope this helps!
After facing so many troubles, here is the solution that I found.
open that file in any text editor and find your missing file ItemGroup.
<ItemGroup>
<None Include="..." />
</ItemGroup>
remove that ItemGroup and open once again your project and build
SWIFT 5, Xcode 11.0
Pass your (date in string) in "dateString" and in "dateFormat" pass format you want. To choose format, use NDateFormatter website.
func getDateFrom(dateString: String, dateFormat: String) -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = dateFormat
dateFormatter.locale = Locale(identifier: "en_US")
guard let date = dateFormatter.date(from: dateString) else {return nil}
return date
}
You can also try change_column_default
in your migrations (tested in Rails 3.2.8):
class SetDefault < ActiveRecord::Migration
def up
# Set default value
change_column_default :people, :last_name, "Smith"
end
def down
# Remove default
change_column_default :people, :last_name, nil
end
end
Use -50%
instead of +50%
They will be aligned to left..
I think you have to draw the listitems yourself to achieve this.
Here's a post with the same kind of question.
Try this
$("[id*='type']").click(
function () {
var isCheckboxChecked = this.checked;
$("[id*='type']").attr('checked', false);
this.checked = isCheckboxChecked;
});
To make it even more generic you can also find checkboxes by the common class implemented on them.

What about this recursive method?
private static int length = 0;
public static int length(int n) {
length++;
if((n / 10) < 10) {
length++;
} else {
length(n / 10);
}
return length;
}
There are many ways, one is to use a counter:
$i = 0;
foreach ($arr as $k => $v) {
/* Do stuff */
if (++$i == 2) break;
}
Other way would be to slice the first 2 elements, this isn't as efficient though:
foreach (array_slice($arr, 0, 2) as $k => $v) {
/* Do stuff */
}
You could also do something like this (basically the same as the first foreach, but with for):
for ($i = 0, reset($arr); list($k,$v) = each($arr) && $i < 2; $i++) {
}
I had the same problem, but it turned out to be a chrome extension called hola (or Proxy SwitchySharp), that messed with the proxy settings. Removing Hola fixed the problem
This question has been out here a long time, but I wanted to contribute how I usually iterate through a JSON object. In the example below, I've shown a hard-coded string that contains the JSON, but the JSON string could just as easily have come from a web service or a file.
import json
def main():
# create a simple JSON array
jsonString = '{"key1":"value1","key2":"value2","key3":"value3"}'
# change the JSON string into a JSON object
jsonObject = json.loads(jsonString)
# print the keys and values
for key in jsonObject:
value = jsonObject[key]
print("The key and value are ({}) = ({})".format(key, value))
pass
if __name__ == '__main__':
main()
It is true that there aren't "before triggers" in MSSQL. However, you could still track the changes that were made on the table, by using the "inserted" and "deleted" tables together. When an update causes the trigger to fire, the "inserted" table stores the new values and the "deleted" table stores the old values. Once having this info, you could relatively easy simulate the "before trigger" behaviour.
You're looking for the onclose event.
see: https://developer.mozilla.org/en/DOM/window.onclose
note that not all browsers support this (for example firefox 2)
I am also faced same problem.
If you're adding a new field then it gives the error as no column found.
Then you apply make migration
command and after that migrate
command
Then still same error..
EX...
path=models.FilePathField()
Add default value for field
path=models.FilePathField(default='')
and than apply command
python manage.py makemigrations
python manage.py migrate
It may help you
The top-rated answer with NVL is totally valid. If you have any interest in making your SQL code more portable, you might want to use CASE, which is supported with the same syntax in both Oracle and SQL Server:

then 0
else regular
end
+
case when overtime is null
then 0
else overtime
end

If you're in charge (or have any control over the web service), get them to add a unique root element!
If you can't change that at all, then you can do a bit of regex or string-splitting to parse each and pass each element to your XML Reader.
Alternatively, you could manually add a junk root element, by prefixing an opening tag and suffixing a closing tag.
[Edit] After reviewing the Mongoose documentation, it looks like you can send each query result as a separate chunk; the web server uses chunked transfer encoding by default so all you have to do is wrap an array around the items to make it a valid JSON object.
Roughly (untested):
app.get('/users/:email/messages/unread', function(req, res, next) {
var firstItem=true, query=MessageInfo.find(/*...*/);
res.writeHead(200, {'Content-Type': 'application/json'});
query.each(function(docs) {
// Start the JSON array or separate the next element.
res.write(firstItem ? (firstItem=false,'[') : ',');
res.write(JSON.stringify({ msgId: msg.fileName }));
});
res.end(']'); // End the JSON array and response.
});
Alternatively, as you mention, you can simply send the array contents as-is. In this case the response body will be buffered and sent immediately, which may consume a large amount of additional memory (above what is required to store the results themselves) for large result sets. For example:
// ...
var query = MessageInfo.find(/*...*/);
res.writeHead(200, {'Content-Type': 'application/json'});
res.end(JSON.stringify(query.map(function(x){ return x.fileName })));
You can actually use a JavaScriptConverter to accomplish this with the built-in JavaScriptSerializer. By converting your enum to a Uri you can encode it as a string.
I've described how to do this for dates but it can be used for enums as well. Custom DateTime JSON Format for .NET JavaScriptSerializer.
I was already using Pillow
and got the same error.
Tried installing libjpeg
or libjpeg-dev
as suggested by others but was told that a (newer) version was already installed.
In the end all it took was reinstalling Pillow
:
sudo pip uninstall Pillow
sudo pip install Pillow
When I now just use the command: mysql
I get: Command 'mysql' not found, but can be installed with:
sudo apt install mysql-client-core-8.0 # version 8.0.22-0ubuntu0.20.04.2, or sudo apt install mariadb-client-core-10.3 # version 1:10.3.25-0ubuntu0.20.04.1
Very helpfull.
In windows, if Python is installed into the default directory (For me it is):
cd C:\Python27
You then proceed to type
"python.exe "[FULLPATH]\[name].py"
to run your Python script in Command Prompt
For an associative array you can just use merge.
$arr = array('item2', 'item3', 'item4');
$arr = array_merge(array('item1'), $arr)
I just spent some serious time figuring some things out with React and scrolling events / positions - so for those still looking, here's what I found:
The viewport height can be found by using window.innerHeight or by using document.documentElement.clientHeight. (Current viewport height)
The height of the entire document (body) can be found using window.document.body.offsetHeight.
If you're attempting to find the height of the document and know when you've hit the bottom - here's what I came up with:
if (window.pageYOffset >= this.myRefII.current.clientHeight && Math.round((document.documentElement.scrollTop + window.innerHeight)) < document.documentElement.scrollHeight - 72) {
this.setState({
trueOrNot: true
});
} else {
this.setState({
trueOrNot: false
});
}
}
(My navbar was 72px in fixed position, thus the -72 to get a better scroll-event trigger)
Lastly, here are a number of scroll commands to console.log(), which helped me figure out my math actively.
console.log('window inner height: ', window.innerHeight);
console.log('document Element client hieght: ', document.documentElement.clientHeight);
console.log('document Element scroll hieght: ', document.documentElement.scrollHeight);
console.log('document Element offset height: ', document.documentElement.offsetHeight);
console.log('document element scrolltop: ', document.documentElement.scrollTop);
console.log('window page Y Offset: ', window.pageYOffset);
console.log('window document body offsetheight: ', window.document.body.offsetHeight);
Whew! Hope it helps someone!

Checkout this thread, it has some useful information about exiting and tracebacks.
If you are more interested in just killing the program, try something like this (this will take the legs out from under the cleanup code as well):
if __name__ == '__main__':
try:
main()
except KeyboardInterrupt:
print('Interrupted')
try:
sys.exit(0)
except SystemExit:
os._exit(0)
As noted by Riedsio, the session variables do not change after connecting unless you specifically set them; setting the global variable only changes the session value of your next connection.
For example, if you have 100 connections and you lower the global wait_timeout
then it will not affect the existing connections, only new ones after the variable was changed.
Specifically for the wait_timeout
variable though, there is a twist.
If you are using the mysql
client in the interactive mode, or the connector with CLIENT_INTERACTIVE
set via mysql_real_connect()
then you will see the interactive_timeout
set for @@session.wait_timeout
Here you can see this demonstrated:
> ./bin/mysql -Bsse 'select @@session.wait_timeout, @@session.interactive_timeout, @@global.wait_timeout, @@global.interactive_timeout'
70 60 70 60
> ./bin/mysql -Bsse 'select @@wait_timeout'
70
> ./bin/mysql

From a linguistic point of view empty has a meaning of without value. Like the others said you'll have to use isset()
in order to check if a variable has been defined, which is what you do.
Many of the answers here are wrong. It seems people figure out what was causing status==0 in their particular case and then generalize that as the answer.
Practically speaking, status==0 for a failed XmlHttpRequest should be considered an undefined error.
The actual W3C spec defines the conditions for which zero is returned here: https://fetch.spec.whatwg.org/#concept-network-error
As you can see from the spec (fetch or XmlHttpRequest) this code could be the result of an error that happened even before the server is contacted.
Some of the common situations that produce this status code are reflected in the other answers but it could be any or none of these problems:
What would be helpful would be for browsers to provide detailed error reporting for more of these status==0 scenarios. Indeed, sometimes status==0 will accompany a helpful console message, but in others there is no other information.
Here is code not using the percentage in the keyframes. Because you used percentages the animation does nothing a long time.
How does this example work:

When using Bash, the first of ~/.bash_profile
, ~/.bash_login
and ~/.profile
will be run for an interactive login shell. I believe ~/.profile
is generally run by Unix shells besides Bash. Bash will run ~/.bashrc
for a non-login interactive shell.
I typically put everything I want to always set in .bashrc
and then run it from .bash_profile
, where I also set up a few things that should run only when I'm logging in, such as setting up ssh-agent
or running screen
.
Alert will block the program flow so you can just write the following.
echo ("<script LANGUAGE='JavaScript'>
window.alert('Succesfully Updated');
window.location.href='http://someplace.com';
</script>");
With your question edit, I see your problem. Let's say the current directory is /home/yourname
... in this case, your command below:
sed 's/xxx/'$PWD'/'
will be expanded to
sed `s/xxx//home/yourname//
which is not valid. You need to put a \
character in front of each /
in your $PWD if you want to do this.
I think you can open the setup.py, locate the package name, and then ask pip to uninstall it.
Assuming the name is available in a 'METADATA' variable:
pip uninstall $(python -c "from setup import METADATA; print METADATA['name']")
If you need to conditionally apply inline styles (apply all or nothing) then this notation also works:
style={ someCondition ? { textAlign:'center', paddingTop: '50%'} : {}}
In case 'someCondition' not fulfilled then you pass empty object.
I wrote a bash script that should automate the process written by Yakov Fain below. It can be called like ./removeComponent myComponentName This has only been tested with Angular 6
#!/bin/bash
if [ "$#" -ne 1 ]; then
echo "Input a component to delete"
exit 1
fi
# finds folder with component name and deletes
find . -type d -name $1 | xargs rm -rf
# removes lines referencing the component from app.module.ts
grep -v $1 app.module.ts > temp
mv temp app.module.ts
componentName=$1
componentName+="Component"
grep -v -i $componentName app.module.ts > temp
mv temp app.module.ts
For me, I open the projectname.xcworkspace file and it all works.

http://vim.wikia.com/wiki/Search_and_replace
Try this search and replace:
:%s/foo/bar/gc
Change each 'foo' to 'bar', but ask for confirmation first.
Press y or n to change or keep your text.
If you have a fixed height in your container, you can set line-height to be the same as height, and it will center vertically. Then just add text-align to center horizontally.
Here's an example: http://jsfiddle.net/Cthulhu/QHEnL/1/
EDIT
Your code should look like this:
.img_thumb {
float: left;
height: 120px;
margin-bottom: 5px;
margin-left: 9px;
position: relative;
width: 147px;
background-color: rgba(0, 0, 0, 0.5);
border-radius: 3px;
line-height:120px;
text-align:center;
}
.img_thumb img {
vertical-align: middle;
}
The images will always be centered horizontally and vertically, no matter what their size is. Here's 2 more examples with images with different dimensions:
http://jsfiddle.net/Cthulhu/QHEnL/6/
http://jsfiddle.net/Cthulhu/QHEnL/7/
UPDATE
It's now 2016 (the future!) and looks like a few things are changing (finally!!).
Back in 2014, Microsoft announced that it will stop supporting IE8 in all versions of Windows and will encourage all users to update to IE11 or Edge. Well, this is supposed to happen next Tuesday (12th January).
Why does this matter? With the announced death of IE8, we can finally start using CSS3 magic.
With that being said, here's an updated way of aligning elements, both horizontally and vertically:
.container {
position: relative;
}
.container .element {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
Using this transform: translate();
method, you don't even need to have a fixed height in your container, it's fully dynamic. Your element has fixed height or width? Your container as well? No? It doesn't matter, it will always be centered because all centering properties are fixed on the child, it's independent from the parent. Thank you CSS3.
If you only need to center in one dimension, you can use translateY
or translateX
. Just try it for a while and you'll see how it works. Also, try to change the values of the translate
, you will find it useful for a bunch of different situations.
Here, have a new fiddle: https://jsfiddle.net/Cthulhu/1xjbhsr4/
For more information on transform
, here's a good resource.
Happy coding.
First thing you do is serialize, then you can do deserialize.
so when you do serialize, you should use @JsonTypeInfo
to let jackson write class information into your json data. What you can do is like this:
Class Data <T> {
int found;
@JsonTypeInfo(use=JsonTypeInfo.Id.CLASS, include=JsonTypeInfo.As.PROPERTY, property="@class")
Class<T> hits
}
Then when you deserialize, you will find jackson has deserialize your data into a class which your variable hits actually is at runtime.
Simply replace it;
SELECT REPLACE(fld_or_variable, ' ', '')
Edit:
Just to clarify; its a global replace, there is no need to trim()
or worry about multiple spaces for either char
or varchar
:
create table #t (
c char(8),
v varchar(8))
insert #t (c, v) values
('a a' , 'a a' ),
('a a ' , 'a a ' ),
(' a a' , ' a a' ),
(' a a ', ' a a ')
select
'"' + c + '"' [IN], '"' + replace(c, ' ', '') + '"' [OUT]
from #t
union all select
'"' + v + '"', '"' + replace(v, ' ', '') + '"'
from #t
Result
IN OUT
===================
"a a " "aa"
"a a " "aa"
" a a " "aa"
" a a " "aa"
"a a" "aa"
"a a " "aa"
" a a" "aa"
" a a " "aa"
Assuming Customer
has a setter for email - myList.get(3).setEmail("[email protected]")
I know this is an old question. But i couldnt get the jquery $(this).change() event to fire correctly onSelect. So i went with the following approach to fire the change event via vanilla js.
$('.date').datepicker({
showOn: 'focus',
dateFormat: 'mm-dd-yy',
changeMonth: true,
changeYear: true,
onSelect: function() {
var event;
if(typeof window.Event == "function"){
event = new Event('change');
this.dispatchEvent(event);
} else {
event = document.createEvent('HTMLEvents');
event.initEvent('change', false, false);
this.dispatchEvent(event);
}
}
});
You can try with this, it worked for me
WebView wb_previewSurvey=new WebView(this);
wb_previewSurvey.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
//Required functionality here
return super.onJsAlert(view, url, message, result);
}
});
Works with single ax or with matrix of ax (subplots)
from matplotlib import pyplot as plt
import numpy as np
def show_values_on_bars(axs):
def _show_on_single_plot(ax):
for p in ax.patches:
_x = p.get_x() + p.get_width() / 2
_y = p.get_y() + p.get_height()
value = '{:.2f}'.format(p.get_height())
ax.text(_x, _y, value, ha="center")
if isinstance(axs, np.ndarray):
for idx, ax in np.ndenumerate(axs):
_show_on_single_plot(ax)
else:
_show_on_single_plot(axs)
fig, ax = plt.subplots(1, 2)
show_values_on_bars(ax)
Give the div a class or id and do something like this:
$("#example").get().innerHTML;
That works at the DOM level.
There are two ways for writing a proper media queries in css. If you are writing media queries for larger device first, then the correct way of writing will be:
@media only screen
and (min-width : 415px){
/* Styles */
}
@media only screen
and (min-width : 769px){
/* Styles */
}
@media only screen
and (min-width : 992px){
/* Styles */
}
But if you are writing media queries for smaller device first, then it would be something like:
@media only screen
and (max-width : 991px){
/* Styles */
}
@media only screen
and (max-width : 768px){
/* Styles */
}
@media only screen
and (max-width : 414px){
/* Styles */
}
Why not just the good ol' javascript?
