Check the location whether it's the right location of the git project.
As long as you clearly reference the other commit from the empty commit it should be fine. Something like:
Commit message errata for [commit sha1]
[new commit message]
As others have pointed out, this is often preferable to force pushing a corrected commit.
It just reminds you the differences between the current branch and the branch which does the current track. Please provide more info, including what branch is printed in the message and where do you push/pull the current branch.
Alternatively:
git push origin +364705c23011b0fc6a7ca2d80c86cef4a7c4db7ac8^:master
Force the master branch of the origin remote repository to the parent of last commit
It's not a Git error message, it's the editor as git uses your default editor.
To solve this:
If you are using the Git GUI, you can amend the last commit which hasn't been pushed with:
Commit/Amend Last Commit
It is not very good to re-write the history. If we use git revert <commit_id>
, it creates a clean reverse-commit of the said commit id.
This way, the history is not re-written, instead, everyone knows that there has been a revert.
One of my first projects as a programmer was a gem called stagecoach that (among other things) allowed the automatic adding of a github issue number to every commit message on a branch, which is a part of the question that hasn't really been answered.
Essentially when creating a branch you'd use a custom command (something like stagecoach -b <branch_name> -g <issue_number>
), and the issue number would then be assigned to that branch in a yml file. There was then a commit hook that appended the issue number to the commit message automatically.
I wouldn't recommend it for production use as at the time I'd only been programming for a few months and I no longer maintain it, but it may be of interest to somebody.
For those very beginners
who has spend few hours for this commit (with comment
and no verify
) with no further issue
git commit -m "Some comments" --no-verify
That simple solution works fine for me:
git rm $(git ls-files --deleted)
Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.
It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.
I think you haven't messed up yet. Try:
git reset HEAD^
This will bring the dir to state before you've made the commit, HEAD^
means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).
If nothing worked use git rm filename to delete file from disk and add it back.
I searched for multiple options to get my git reset to specific commit, but most of them aren't so satisfactory.
I generally use this to reset the git to the specific commit in source tree.
select commit to reset on sourcetree.
In dropdowns select the active branch , first Parent Only
And right click on "Reset branch to this commit" and select hard reset option (soft, mixed and hard)
and then go to terminal git push -f
You should be all set!
I had the same issue because I had 2 .git
folders in the working directory.
Your problem may be caused by the same thing, so I recommend checking to see if you have multiple .git
folders, and, if so, deleting one of them.
That allowed me to upload the project successfully.
If you enter git commit
but omit to enter a comment using the –m
parameter, then Git will open up the default editor for you to edit your check-in note. By default that is Vim. Now you can do two things:
Alternative 1 – Exit Vim without entering any comment and repeat
A blank or unsaved comment will be counted as an aborted attempt to commit your changes and you can exit Vim by following these steps:
Press Esc to make sure you are not in edit mode (you can press Esc several times if you are uncertain)
Type :q!
enter
(that is, colon, letter q, exclamation mark, enter), this tells Vim to discard any changes and exit)
Git will then respond:
Aborting commit due to empty commit message
and you are once again free to commit using:
git commit –m "your comment here"
Alternative 2 – Use Vim to write a comment
Follow the following steps to use Vim for writing your comments
:wq

To extend on the accepted answer, you can also do:
git commit --amend --no-edit -a
to add the currently changed files.
Just delete the Github repo and create a new one. By far the fastest, easiest and safest approach. After all, what do you have to gain carrying out all those commands in the accepted solution when all you want is the master branch with a single commit?
I think you may also use the command line :
git add -p
This allows you to review all your uncommited files, one by one and choose if you want to commit them or not.
Then you have some options that will come up for each modification: I use the "y" for "yes I want to add this file" and the "n" for "no, I will commit this one later".
Stage this hunk [y,n,q,a,d,K,g,/,e,?]?
As for the other options which are ( q,a,d,K,g,/,e,? ), I'm not sure what they do, but I guess the "?" might help you out if you need to go deeper into details.
The great thing about this is that you can then push your work, and create a new branch after and all the uncommited work will follow you on that new branch. Very useful if you have coded many different things and that you actually want to reorganise your work on github before pushing it.
Hope this helps, I have not seen it said previously (if it was mentionned, my bad)
First you need to add all untracked files. Use this command line:
git add *
Then commit using this command line :
git commit -a
Instead of telling you how you could execute a certain command (Esc:wq), I can provide you two links that may help you with VIM:
However, the best way to learn Vim is not only using it for Git commits, but as a regular editor for your everyday work.
If you're not going to switch to Vim, it's nonsense to keep its commands in mind. In that case, go and set up your favourite editor to use with Git.
There are two commands which will work in this situation,
root>git reset --hard HEAD~1
root>git push -f
For more git commands refer this page
Use:
git reset HEAD filepath
For example:
git reset HEAD om211/src/META-INF/persistence.xml
The first thing you should do is to determine whether you want to keep the local changes before you delete the commit message.
Use git log
to show current commit messages, then find the commit_id
before the commit that you want to delete, not the commit you want to delete.
git reset --soft commit_id
git reset --hard commit_id
That's the difference of soft and hard
The advice you were given is flawed. Unconditionally setting GIT_AUTHOR_DATE in an --env-filter
would rewrite the date of every commit. Also, it would be unusual to use git commit inside --index-filter
.
You are dealing with multiple, independent problems here.
Each commit has two dates: the author date and the committer date. You can override each by supplying values through the environment variables GIT_AUTHOR_DATE and GIT_COMMITTER_DATE for any command that writes a new commit. See “Date Formats” in git-commit(1) or the below:
Git internal format = <unix timestamp> <time zone offset>, e.g. 1112926393 +0200
RFC 2822 = e.g. Thu, 07 Apr 2005 22:13:13 +0200
ISO 8601 = e.g. 2005-04-07T22:13:13
The only command that writes a new commit during normal use is git commit. It also has a --date
option that lets you directly specify the author date. Your anticipated usage includes git filter-branch --env-filter
also uses the environment variables mentioned above (these are part of the “env” after which the option is named; see “Options” in git-filter-branch(1) and the underlying “plumbing” command git-commit-tree(1).
If your repository is very simple (i.e. you only have a single branch, no tags), then you can probably use git rebase to do the work.
In the following commands, use the object name (SHA-1 hash) of the commit instead of “A”. Do not forget to use one of the “date override” methods when you run git commit.
---A---B---C---o---o---o master
git checkout master
git checkout A~0
git add path/to/file
git commit --date='whenever'
git tag ,new-commit -m'delete me later'
git checkout -
git rebase --onto ,new-commit A
git tag -d ,new-commit
---A---N (was ",new-commit", but we delete the tag)
\
B'---C'---o---o---o master
If you wanted to update A to include the new file (instead of creating a new commit where it was added), then use git commit --amend
instead of git commit
. The result would look like this:
---A'---B'---C'---o---o---o master
The above works as long as you can name the commit that should be the parent of your new commit. If you actually want your new file to be added via a new root commit (no parents), then you need something a bit different:
B---C---o---o---o master
git checkout master
git checkout --orphan new-root
git rm -rf .
git add path/to/file
GIT_AUTHOR_DATE='whenever' git commit
git checkout -
git rebase --root --onto new-root
git branch -d new-root
N (was new-root, but we deleted it)
\
B'---C'---o---o---o master
git checkout --orphan
is relatively new (Git 1.7.2), but there are other ways of doing the same thing that work on older versions of Git.
If your repository is more complex (i.e. it has more than one ref (branches, tags, etc.)), then you will probably need to use git filter-branch. Before using git filter-branch, you should make a backup copy of your entire repository. A simple tar archive of your entire working tree (including the .git directory) is sufficient. git filter-branch does make backup refs, but it is often easier to recover from a not-quite-right filtering by just deleting your .git
directory and restoring it from your backup.
Note: The examples below use the lower-level command git update-index --add
instead of git add
. You could use git add, but you would first need to copy the file from some external location to the expected path (--index-filter
runs its command in a temporary GIT_WORK_TREE that is empty).
If you want your new file to be added to every existing commit, then you can do this:
new_file=$(git hash-object -w path/to/file)
git filter-branch \
--index-filter \
'git update-index --add --cacheinfo 100644 '"$new_file"' path/to/file' \
--tag-name-filter cat \
-- --all
git reset --hard
I do not really see any reason to change the dates of the existing commits with --env-filter 'GIT_AUTHOR_DATE=…'
. If you did use it, you would have make it conditional so that it would rewrite the date for every commit.
If you want your new file to appear only in the commits after some existing commit (“A”), then you can do this:
file_path=path/to/file
before_commit=$(git rev-parse --verify A)
file_blob=$(git hash-object -w "$file_path")
git filter-branch \
--index-filter '
if x=$(git rev-list -1 "$GIT_COMMIT" --not '"$before_commit"') &&
test -n "$x"; then
git update-index --add --cacheinfo 100644 '"$file_blob $file_path"'
fi
' \
--tag-name-filter cat \
-- --all
git reset --hard
If you want the file to be added via a new commit that is to be inserted into the middle of your history, then you will need to generate the new commit prior to using git filter-branch and add --parent-filter
to git filter-branch:
file_path=path/to/file
before_commit=$(git rev-parse --verify A)
git checkout master
git checkout "$before_commit"
git add "$file_path"
git commit --date='whenever'
new_commit=$(git rev-parse --verify HEAD)
file_blob=$(git rev-parse --verify HEAD:"$file_path")
git checkout -
git filter-branch \
--parent-filter "sed -e s/$before_commit/$new_commit/g" \
--index-filter '
if x=$(git rev-list -1 "$GIT_COMMIT" --not '"$new_commit"') &&
test -n "$x"; then
git update-index --add --cacheinfo 100644 '"$file_blob $file_path"'
fi
' \
--tag-name-filter cat \
-- --all
git reset --hard
You could also arrange for the file to be first added in a new root commit: create your new root commit via the “orphan” method from the git rebase section (capture it in new_commit
), use the unconditional --index-filter
, and a --parent-filter
like "sed -e \"s/^$/-p $new_commit/\""
.
Intellij IDEA (and I guess all other products of the series) has built in support for partial commits since v2018.1
Stick with the present tense imperative because
I had the same problem.
As a Git-newbie, I thought it was complete FUBAR.
Solution: Somewhat like @bara suggested + created a local backup branch
# Rewind to commit just before the pushed-and-amended one.
# Replace <hash> with the needed hash.
# --soft means: leave all the changes there, so nothing is lost.
git reset --soft <hash>
# Create new branch, just for a backup, still having all changes in it.
# The branch was feature/1234, new one - feature/1234-gone-bad
git checkout -b feature/1234-gone-bad
# Commit all the changes (all the mess) not to lose it & not to carry around
git commit -a -m "feature/1234 backup"
# Switch back to the original branch
git checkout feature/1234
# Pull the from remote (named 'origin'), thus 'repairing' our main problem
git pull origin/feature/1234
# Now you have a clean-and-non-diverged branch and a backup of the local changes.
# Check the needed files from the backup branch
git checkout feature/1234-gone-bad -- the/path/to/file.php
Maybe it's not a fast and clean solution, and I lost my history (1 commit instead of 5), but it saved a day's work.
This is considered as features in Gitlab.
Maintainer / Owner
access is never able to force push again for default & protected branch, as stated in this docs
In these cases, the "reset" command is your best friend:
git reset --soft HEAD~1
Reset will rewind your current HEAD branch to the specified revision. In our example above, we'd like to return to the one before the current revision - effectively making our last commit undone.
Note the --soft flag: this makes sure that the changes in undone revisions are preserved. After running the command, you'll find the changes as uncommitted local modifications in your working copy.
If you don't want to keep these changes, simply use the --hard flag. Be sure to only do this when you're sure you don't need these changes anymore.
git reset --hard HEAD~1
There is also a lazy approach to this problem, especially if you have more than one commit that you want to change. In my case, I had a new branch with several commits with a wrong author, so what helped me:
Go to your original branch:
git checkout develop
Create new branch from it:
git checkout -b myFeature develop
Merge it without commit info as one commit:
git merge --no-commit --squash branchWrongAuthor
You might also want to stage changes:
git stage .
Change the name of the author and commit changes:
git commit --amend --author "New Author Name <New Author Email>" -m "new feature added"
And that's it, you can push the changes.
git push
You can delete the branch with a wrong author after that.
Had the same issue where I have changes in a local branch where I wanted to revert just one file. What worked for me was -
(feature/target_branch below is where I have all my changes including those I wanted to undo for a specific file)
(origin/feature/target_branch is the remote branch where I want to push my changes to)
(feature/staging is my temporary staging branch where I will be pushing from all my wanted changes excluding the change to that one file)
Create a local branch from my origin/feature/target_branch - called it feature/staging
Merged my working local branch feature/target_branch to the feature/staging branch
Checked out feature/staging then git reset --soft ORIG_HEAD (Now all changes from the feature/staging' will be staged but uncommitted.)
Unstaged the file which I have previously checked in with unnecessary changes
Changed the upstream branch for feature/staging to origin/feature/target_branch
Committed the rest of the staged changes and pushed upstream to my remote origin/feature/target_branch
If you already pushed your changes, you will need to force your next push after resetting the HEAD.
git reset --hard HEAD^
git merge COMMIT_SHA1
git push --force
Warning: a hard reset will undo any uncommitted modifications in your working copy, while a force push will completely overwrite the state of the remote branch with the current state of the local branch.
Just in case, on Windows (using the Windows command line, not Bash) it's actually four ^^^^
instead of one, so it's
git reset --hard HEAD^^^^
Well, basically git commit puts your changes into your local repo, while git push sends your changes to the remote location. Since git is a distributed version control system, the difference is that commit will commit changes to your local repository, whereas push will push changes up to a remote repo

In my android project I had admob_keys.xml as separated xml file in app/src/main/res/values/ folder. To remove this sensitive file I used below script and worked perfectly.

You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else.
By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment
in order to find the action.
Checkout the files in https://github.com/PyCQA/pylint/tree/master/pylint/checkers. I haven't found a better way to obtain the error name from a message than either Ctrl + F-ing those files or using the GitHub search feature:
If the message is "No name ... in module ...", use the search:
No name %r in module %r repo:PyCQA/pylint/tree/master path:/pylint/checkers
Or, to get fewer results:
"No name %r in module %r" repo:PyCQA/pylint/tree/master path:/pylint/checkers
GitHub will show you:
"E0611": (
"No name %r in module %r",
"no-name-in-module",
"Used when a name cannot be found in a module.",
You can then do:
from collections import Sequence # pylint: disable=no-name-in-module
You should use contains not matches
if(nom.contains("."))
System.out.println("OK");
else
System.out.println("Bad");
Both do different things.
The first creates an object with automatic storage duration. It is created, used, and then goes out of scope when the current block ({ ... }
) ends. It's the simplest way to create an object, and is just the same as when you write int x = 0;
The second creates an object with dynamic storage duration and allows two things:
Fine control over the lifetime of the object, since it does not go out of scope automatically; you must destroy it explicitly using the keyword delete
;
Creating arrays with a size known only at runtime, since the object creation occurs at runtime. (I won't go into the specifics of allocating dynamic arrays here.)
Neither is preferred; it depends on what you're doing as to which is most appropriate.
Use the former unless you need to use the latter.
Your C++ book should cover this pretty well. If you don't have one, go no further until you have bought and read, several times, one of these.
Good luck.
Your original code is broken, as it delete
s a char
array that it did not new
. In fact, nothing new
d the C-style string; it came from a string literal. delete
ing that is an error (albeit one that will not generate a compilation error, but instead unpredictable behaviour at runtime).
Usually an object should not have the responsibility of delete
ing anything that it didn't itself new
. This behaviour should be well-documented. In this case, the rule is being completely broken.
You need to load the URL Helper in order to use base_url()
. In your controller, do:
$this->load->helper('url');
Then in your view you can do:
echo base_url();
This is a quick workaround (but not recommended) to add this in the plist:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
Which means (according to Apple's documentation):
NSAllowsArbitraryLoads
A Boolean value used to disable App Transport Security for any domains not listed in the NSExceptionDomains dictionary. Listed domains use the settings specified for that domain.The default value of NO requires the default App Transport Security behaviour for all connections.
I really recommend links:
which help me understand reasons and all the implications.
The XML (in file Info.plist) below will:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<false/>
<key>NSExceptionDomains</key>
<dict>
<key>PAGE_FOR_WHICH_SETTINGS_YOU_WANT_TO_OVERRIDE</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
</dict>
</dict>
</dict>
disallow arbitrary calls for all pages, but for PAGE_FOR_WHICH_SETTINGS_YOU_WANT_TO_OVERRIDE
will allow that connections use the HTTP protocol.
To the XML above you can add:
<key>NSIncludesSubdomains</key>
<true/>
if you want to allow insecure connections for the subdomains of the specified address.
The best approach is to block all arbitrary loads (set to false) and add exceptions to allow only addresses we know are fine.
2018 Update:
Apple is not recommending switching this off - more information can be found in 207 session WWDC 2018 with more things explained in regards to security

If you landed here just wondering how to limit to 2 decimal places I have a native javascript solution:
Javascript:
function limitDecimalPlaces(e, count) {
if (e.target.value.indexOf('.') == -1) { return; }
if ((e.target.value.length - e.target.value.indexOf('.')) > count) {
e.target.value = parseFloat(e.target.value).toFixed(count);
}
}
HTML:
<input type="number" oninput="limitDecimalPlaces(event, 2)" />
Note that this cannot AFAIK, defend against this chrome bug with the number input.
I had the same issue and I solved it by using:
display: inline-block;
on the div
in question.
Daniel's answer seems to work fine for now, but please note that generating absolute urls using twig's asset
function is now deprecated:
DEPRECATED - Generating absolute URLs with the Twig asset() function was deprecated in 2.7 and will be removed in 3.0. Please use absolute_url() instead.
Here's the official announcement: http://symfony.com/blog/new-in-symfony-2-7-the-new-asset-component#template-function-changes
You have to use the absolute_url
twig function:
{# Symfony 2.6 #}
{{ asset('logo.png', absolute = true) }}
{# Symfony 2.7 #}
{{ absolute_url(asset('logo.png')) }}
It is interesting to note that it also works with path
function:
{{ absolute_url(path('index')) }}
Since lua 5.3 there is a new math.tointeger
function for string to integer. Just for integer, no float.
For example:
print(math.tointeger("10.1")) -- nil
print(math.tointeger("10")) -- 10
If you want to convert integer and float, the tonumber
function is more appropriate.
Just to show it in a different format that I prefer to use for some reason: The first way returns your itemList as an System.Linq.IOrderedQueryable
using(var context = new ItemEntities())
{
var itemList = context.Items.Where(x => !x.Items && x.DeliverySelection)
.OrderByDescending(x => x.Delivery.SubmissionDate);
}
That approach is fine, but if you wanted it straight into a List Object:
var itemList = context.Items.Where(x => !x.Items && x.DeliverySelection)
.OrderByDescending(x => x.Delivery.SubmissionDate).ToList();
All you have to do is append a .ToList() call to the end of the Query.
Something to note, off the top of my head I can't recall if the !(not) expression is acceptable in the Where() call.
I was recently faced with this problem, and with no simple solution since my fields can be prepopulated, I wanted to share an elegant hack I came up with by setting password type in the ready event.
Don't declare your input field as type password when creating it, but add a ready event listener to add it for you:
function createSecretTextInput(name,parent){
var createInput = document.createElement("input");
createInput.setAttribute('name', name);
createInput.setAttribute('class', 'secretText');
createInput.setAttribute('id', name+'SecretText');
createInput.setAttribute('value', 'test1234');
if(parent==null)
document.body.appendChild(createInput);
else
document.getElementById(parent).appendChild(createInput);
$(function(){
document.getElementById(name+'SecretText').setAttribute('type', 'password');
});
};
createSecretTextInput('name', null);
Just wanted to add on to what @aioobe mentioned above...
In that approach you use HTML to color code your text. Though this is one of the most frequently used ways to color code the label text, but is not the most efficient way to do it.... considering that fact that each label will lead to HTML being parsed, rendering, etc. If you have large UI forms to be displayed, every millisecond counts to give a good user experience.
You may want to go through the below and give it a try....
Jide OSS (located at https://jide-oss.dev.java.net/) is a professional open source library with a really good amount of Swing components ready to use. They have a much improved version of JLabel named StyledLabel. That component solves your problem perfectly... See if their open source licensing applies to your product or not.
This component is very easy to use. If you want to see a demo of their Swing Components you can run their WebStart demo located at www.jidesoft.com (http://www.jidesoft.com/products/1.4/jide_demo.jnlp). All of their offerings are demo'd... and best part is that the StyledLabel is compared with JLabel (HTML and without) in terms of speed! :-)
A screenshot of the perf test can be seen at (http://img267.imageshack.us/img267/9113/styledlabelperformance.png)
Use the CSS white-space property instead of opening yourself up to XSS vulnerabilities!

Strangely enough,
package main
func main () {
var sessions = map[string] chan int{};
delete(sessions, "moo");
}
seems to work. This seems a poor use of resources though!
Another way is to check for existence and use the value itself:
package main
func main () {
var sessions = map[string] chan int{};
sessions["moo"] = make (chan int);
_, ok := sessions["moo"];
if ok {
delete(sessions, "moo");
}
}
I had troubles compiling all the most commonly mentioned cryptography libraries on my Windows 7 system and for Python 3.5.
This is the solution that finally worked for me.
from cryptography.fernet import Fernet
key = Fernet.generate_key() #this is your "password"
cipher_suite = Fernet(key)
encoded_text = cipher_suite.encrypt(b"Hello stackoverflow!")
decoded_text = cipher_suite.decrypt(encoded_text)
"Should I clone the list first?"
That will be the easiest solution, remove from the clone, and copy the clone back after removal.
An example from my rummikub game:
SuppressWarnings("unchecked")
public void removeStones() {
ArrayList<Stone> clone = (ArrayList<Stone>) stones.clone();
// remove the stones moved to the table
for (Stone stone : stones) {
if (stone.isOnTable()) {
clone.remove(stone);
}
}
stones = (ArrayList<Stone>) clone.clone();
sortStones();
}
In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("now:", now)
count := 10
then := now.Add(time.Duration(-count) * time.Minute)
// if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
// then := now.Add(-10 * time.Minute)
fmt.Println("10 minutes ago:", then)
}
Produces:
now: 2009-11-10 23:00:00 +0000 UTC
10 minutes ago: 2009-11-10 22:50:00 +0000 UTC
Not to mention, you can also use time.Hour
or time.Second
instead of time.Minute
as per your needs.

One interesting thing is multiple order by:
according to laravel docs:
DB::table('users')
->orderBy('priority', 'desc')
->orderBy('email', 'asc')
->get();
this means laravel will sort result based on priority
attribute. when it's done, it will order result with same priority
based on email
internally.
Upgrade your mysql-connector" lib package with your mysql version like below i am using 8.0.13 version and in pom I changed the version:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
<version>8.0.13</version>
</dependency>
My problem has resolved after this.
If you are using Spring boot and have this issue with the OffsetDateTime then need to use the registerModules as answered above by @greperror(answered May 28 '16 at 13:04) but note that there is one difference. The dependency mentioned doesn't need to be added as I am guessing that spring boot has it already. I was having this issue with Spring boot and it worked for me without adding this dependency.

A JIT compiler runs after the program has started and compiles the code (usually bytecode or some kind of VM instructions) on the fly (or just-in-time, as it's called) into a form that's usually faster, typically the host CPU's native instruction set. A JIT has access to dynamic runtime information whereas a standard compiler doesn't and can make better optimizations like inlining functions that are used frequently.
This is in contrast to a traditional compiler that compiles all the code to machine language before the program is first run.
To paraphrase, conventional compilers build the whole program as an EXE file BEFORE the first time you run it. For newer style programs, an assembly is generated with pseudocode (p-code). Only AFTER you execute the program on the OS (e.g., by double-clicking on its icon) will the (JIT) compiler kick in and generate machine code (m-code) that the Intel-based processor or whatever will understand.
+(BOOL)doesSystemVersionMeetRequirement:(NSString *)minRequirement{
// eg NSString *reqSysVer = @"4.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:minRequirement options:NSNumericSearch] != NSOrderedAscending)
{
return YES;
}else{
return NO;
}
}
You can change the color of the navigation icon programmatically like this:
mToolbar.setNavigationIcon(getColoredArrow());
private Drawable getColoredArrow() {
Drawable arrowDrawable = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
Drawable wrapped = DrawableCompat.wrap(arrowDrawable);
if (arrowDrawable != null && wrapped != null) {
// This should avoid tinting all the arrows
arrowDrawable.mutate();
DrawableCompat.setTintList(wrapped, ColorStateList.valueOf(this.getResources().getColor(R.color.your_color)));
}
}
return wrapped;
}
Try this:
private string GetJArrayValue(JObject yourJArray, string key)
{
foreach (KeyValuePair<string, JToken> keyValuePair in yourJArray)
{
if (key == keyValuePair.Key)
{
return keyValuePair.Value.ToString();
}
}
}
You might be able to workaround this by running initdb -U postgres -D /path/to/data

I know it a little late to answer but I think this short video will help you a lot.
http://www.xlninja.com/2012/07/25/excel-choose-function-explained/
Essentially it is using the choose function. He explains it very well in the video so I'll let do it instead of typing 20 pages.
Another video of his explains how to use data validation to populate a drop down which you can select from a limited range.
http://www.xlninja.com/2012/08/13/excel-data-validation-using-dependent-lists/
You could combine the two and use the value in the drop down as your index to the choose function. While he did not show how to combine them, I'm sure you could figure it out as his videos are good. If you have trouble, let me know and I'll update my answer to show you.
You can use text
.
text(x, y, s, fontsize=12)
text
coordinates can be given relative to the axis, so the position of your text will be independent of the size of the plot:
The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords (0,0 is lower-left and 1,1 is upper-right). The example below places text in the center of the axes::
text(0.5, 0.5,'matplotlib',
horizontalalignment='center',
verticalalignment='center',
transform = ax.transAxes)
To prevent the text to interfere with any point of your scatter is more difficult afaik. The easier method is to set y_axis (ymax in ylim((ymin,ymax))
) to a value a bit higher than the max y-coordinate of your points. In this way you will always have this free space for the text.
EDIT: here you have an example:
In [17]: from pylab import figure, text, scatter, show
In [18]: f = figure()
In [19]: ax = f.add_subplot(111)
In [20]: scatter([3,5,2,6,8],[5,3,2,1,5])
Out[20]: <matplotlib.collections.CircleCollection object at 0x0000000007439A90>
In [21]: text(0.1, 0.9,'matplotlib', ha='center', va='center', transform=ax.transAxes)
Out[21]: <matplotlib.text.Text object at 0x0000000007415B38>
In [22]:
The ha and va parameters set the alignment of your text relative to the insertion point. ie. ha='left' is a good set to prevent a long text to go out of the left axis when the frame is reduced (made narrower) manually.
I just tried out your build.gradle

I have a ListView
comprised of EditText
views. The scenario says that after editing text in one or more row(s) we should click on a button called "finish". I used onFocusChanged
on the EditText
view inside of listView
but after clicking on finish the data is not being saved. The problem was solved by adding
listView.clearFocus();
inside the onClickListener
for the "finish" button and the data was saved successfully.
Make sure your .NET version 4.5 or greater
Actually, to properly support sorting, filtering, etc. a CollectionViewSource should be used as a link between the DataGrid and the list, like this:
<Window.Resources>
<CollectionViewSource x:Key="ItemCollectionViewSource" CollectionViewType="ListCollectionView"/>
</Window.Resources>
The DataGrid line looks like this:
<DataGrid
DataContext="{StaticResource ItemCollectionViewSource}"
ItemsSource="{Binding}"
AutoGenerateColumns="False">
In the code behind, you link CollectionViewSource with your link.
CollectionViewSource itemCollectionViewSource;
itemCollectionViewSource = (CollectionViewSource)(FindResource("ItemCollectionViewSource"));
itemCollectionViewSource.Source = itemList;
For detailed example see my article on CoedProject: http://www.codeproject.com/Articles/683429/Guide-to-WPF-DataGrid-formatting-using-bindings

I whould choose swing just because it's "native" for java.
Plus, have a look at http://swingx.java.net/.
RFC6648 recommends that you assume that your custom header "might become standardized, public, commonly deployed, or usable across multiple implementations." Therefore, it recommends not to prefix it with "X-" or similar constructs.
However, there is an exception "when it is extremely unlikely that [your header] will ever be standardized." For such "implementation-specific and private-use" headers, the RFC says a namespace such as a vendor prefix is justified.
If you are using grep
or sed
the syntax will be a little different. Notice that the sequential [^a][^b]

Here's a complete example in the hope that it helps someone:
git revert -m 1 <commit-hash>
git push -u origin master
Where <commit-hash>
is the commit hash of the merge that you would like to revert, and as stated in the explanation of this answer, -m 1
indicates that you'd like to revert to the tree of the first parent prior to the merge.
The git revert ...
line essentially commits your changes while the second line makes your changes public by pushing them to the remote branch.
I think this example will definitely help you overlay a transparent image on top of another image. This is made possible by drawing both the images on canvas and returning a bitmap image.
Read more or download demo here
private Bitmap createSingleImageFromMultipleImages(Bitmap firstImage, Bitmap secondImage){
Bitmap result = Bitmap.createBitmap(firstImage.getWidth(), firstImage.getHeight(), firstImage.getConfig());
Canvas canvas = new Canvas(result);
canvas.drawBitmap(firstImage, 0f, 0f, null);
canvas.drawBitmap(secondImage, 10, 10, null);
return result;
}
and call the above function on button click and pass the two images to our function as shown below
public void buttonMerge(View view) {
Bitmap bigImage = BitmapFactory.decodeResource(getResources(), R.drawable.img1);
Bitmap smallImage = BitmapFactory.decodeResource(getResources(), R.drawable.img2);
Bitmap mergedImages = createSingleImageFromMultipleImages(bigImage, smallImage);
img.setImageBitmap(mergedImages);
}
For more than two images, you can follow this link, how to merge multiple images programmatically on android
For me just removed the OLE DB source from SSIS and added again. Worked!
Sometimes it doesnt fire when the script has some syntax error, make sure the script and javascript syntax is correct.
Simply supplying the HTML of elements you want to add to a jQuery constructor $()
will return a jQuery object from newly built HTML, suitable for being appended into the DOM using jQuery's append()
method.
For example:
var t = $("<table cellspacing='0' class='text'></table>");
$.append(t);
You could then populate this table programmatically, if you wished.
This gives you the ability to specify any arbitrary HTML you like, including class names or other attributes, which you might find more concise than using createElement
and then setting attributes like cellSpacing
and className
via JS.
You can use .loc
to select the specific columns with all rows and then pull that. An example is below:
pandas.merge(dataframe1, dataframe2.iloc[:, [0:5]], how='left', on='key')
In this example, you are merging dataframe1 and dataframe2. You have chosen to do an outer left join on 'key'. However, for dataframe2 you have specified .iloc
which allows you to specific the rows and columns you want in a numerical format. Using :
, your selecting all rows, but [0:5]
selects the first 5 columns. You could use .loc
to specify by name, but if your dealing with long column names, then .iloc
may be better.
EDIT: As pointed out by users, don't use MQ, use commit --amend
. This answer is mostly of historic interest now.
As others have mentioned the MQ extension is much more suited for this task, and you don't run the risk of destroying your work. To do this:
Enable the MQ extension, by adding something like this to your hgrc:

Update to the changeset you want to edit, typically tip:
hg up $rev
Import the current changeset into the queue:
hg qimport -r .
Refresh the patch, and edit the commit message:
hg qrefresh -e
Finish all applied patches (one, in this case) and store them as regular changesets:
hg qfinish -a
I'm not familiar with TortoiseHg, but the commands should be similar to those above. I also believe it's worth mentioning that editing history is risky; you should only do it if you're absolutely certain that the changeset hasn't been pushed to or pulled from anywhere else.
You can add #define uAppDelegate (AppDelegate *)[[UIApplication sharedApplication] delegate]

A portable way of reading memory and load numbers is the sysinfo
call
#include <sys/sysinfo.h>
int sysinfo(struct sysinfo *info);
Until Linux 2.3.16, sysinfo() used to return information in the
following structure:
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* swap space still available */
unsigned short procs; /* Number of current processes */
char _f[22]; /* Pads structure to 64 bytes */
};
and the sizes were given in bytes.
Since Linux 2.3.23 (i386), 2.3.48 (all architectures) the structure
is:
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* swap space still available */
unsigned short procs; /* Number of current processes */
unsigned long totalhigh; /* Total high memory size */
unsigned long freehigh; /* Available high memory size */
unsigned int mem_unit; /* Memory unit size in bytes */
char _f[20-2*sizeof(long)-sizeof(int)]; /* Padding to 64 bytes */
};
and the sizes are given as multiples of mem_unit bytes.
Prototype or Object.prototype is a property of an object literal. It represents the Object prototype object which you can override to add more properties or methods further along the prototype chain.
__proto__ is an accessor property (get and set function) that exposes the internal prototype of an object thru which it is accessed.

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

In WPF, TextBox element will not get opportunity to use "Enter" button for creating KeyUp Event until you will not set property: AcceptsReturn="True".
But, it would`t solve the problem with handling KeyUp Event in TextBox element. After pressing "ENTER" you will get a new text line in TextBox.
I had solved problem of using KeyUp Event of TextBox element by using Bubble event strategy. It's short and easy. You have to attach a KeyUp Event handler in some (any) parent element:
XAML:
<Window x:Class="TextBox_EnterButtomEvent.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:TextBox_EnterButtomEvent"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid KeyUp="Grid_KeyUp">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height ="0.3*"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="1" Grid.Column="1" Padding="0" TextWrapping="WrapWithOverflow">
Input text end press ENTER:
</TextBlock>
<TextBox Grid.Row="2" Grid.Column="1" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Row="4" Grid.Column="1" Padding="0" TextWrapping="WrapWithOverflow">
You have entered:
</TextBlock>
<TextBlock Name="txtBlock" Grid.Row="5" Grid.Column="1" HorizontalAlignment="Stretch"/>
</Grid></Window>
C# logical part (KeyUp Event handler is attached to a grid element):
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Grid_KeyUp(object sender, KeyEventArgs e)
{
if(e.Key == Key.Enter)
{
TextBox txtBox = e.Source as TextBox;
if(txtBox != null)
{
this.txtBlock.Text = txtBox.Text;
this.txtBlock.Background = new SolidColorBrush(Colors.LightGray);
}
}
}
}
Result:
Content types are included in HTTP responses because the same, byte for byte sequence of values in the content could be interpreted in more than one way.(*)
Remember that http can transport more than just HTML (js, css and images are obvious examples), and in some cases, the receiver will not know what type of object it's going to receive.
(*) the obvious one here is XHTML - which is XML. If it's served with a content type of application/xml
, the receiver ought to just treat it as XML. If it's served up as application/xhtml+xml
, then it ought to be treated as XHTML.
I had the same issue and solved by making sure that 1. when you make the style.css file, make sure you didn't just rename a text file as "style.css", make sure it's really the .css format (e.g, use visual studio code); 2. put that style.css file in the same folder with your .rmd file. Hopefully this works for you.
Use this:
static int RandomNumber(int min, int max)
{
Random random = new Random(); return random.Next(min, max);
}
This is example for you to modify and use in your application.
As far as I can remember, the first versions of C only allowed to return a value that could fit into a processor register, which means that you could only return a pointer to a struct. The same restriction applied to function arguments.
More recent versions allow to pass around larger data objects like structs. I think this feature was already common during the eighties or early nineties.
Arrays, however, can still be passed and returned only as pointers.

timespec_get
from C11
Returns up to nanoseconds, rounded to the resolution of the implementation.
Looks like an ANSI ripoff from POSIX' clock_gettime
.
Example: a printf
is done every 100ms on Ubuntu 15.10:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
static long get_nanos(void) {
struct timespec ts;
timespec_get(&ts, TIME_UTC);
return (long)ts.tv_sec * 1000000000L + ts.tv_nsec;
}
int main(void) {
long nanos;
long last_nanos;
long start;
nanos = get_nanos();
last_nanos = nanos;
start = nanos;
while (1) {
nanos = get_nanos();
if (nanos - last_nanos > 100000000L) {
printf("current nanos: %ld\n", nanos - start);
last_nanos = nanos;
}
}
return EXIT_SUCCESS;
}
The C11 N1570 standard draft 7.27.2.5 "The timespec_get function says":
If base is TIME_UTC, the tv_sec member is set to the number of seconds since an implementation defined epoch, truncated to a whole value and the tv_nsec member is set to the integral number of nanoseconds, rounded to the resolution of the system clock. (321)
321) Although a struct timespec object describes times with nanosecond resolution, the available resolution is system dependent and may even be greater than 1 second.
C++11 also got std::chrono::high_resolution_clock
: C++ Cross-Platform High-Resolution Timer
glibc 2.21 implementation
Can be found under sysdeps/posix/timespec_get.c
as:
int
timespec_get (struct timespec *ts, int base)
{
switch (base)
{
case TIME_UTC:
if (__clock_gettime (CLOCK_REALTIME, ts) < 0)
return 0;
break;
default:
return 0;
}
return base;
}
so clearly:
only TIME_UTC
is currently supported
it forwards to __clock_gettime (CLOCK_REALTIME, ts)
, which is a POSIX API: http://pubs.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html
Linux x86-64 has a clock_gettime
system call.
Note that this is not a fail-proof micro-benchmarking method because:
man clock_gettime
says that this measure may have discontinuities if you change some system time setting while your program runs. This should be a rare event of course, and you might be able to ignore it.
this measures wall time, so if the scheduler decides to forget about your task, it will appear to run for longer.
For those reasons getrusage()
might be a better better POSIX benchmarking tool, despite it's lower microsecond maximum precision.
More information at: Measure time in Linux - time vs clock vs getrusage vs clock_gettime vs gettimeofday vs timespec_get?
Your mistake is using the datetime
module instead of the date
module. You meant to do this:
from datetime import date
date = models.DateField(_("Date"), default=date.today)
If you only want to capture the current date the proper way to handle this is to use the auto_now_add
parameter:
date = models.DateField(_("Date"), auto_now_add=True)
However, the modelfield docs clearly state that auto_now_add
and auto_now
will always use the current date and are not a default value that you can override.
x.each_with_index { |v, i| puts "current index...#{i}" }

Alternatively, you can directly use javascript's window.onresize
As example, my code (using scriptaculos) is :
window.onresize = function (){
var w = $("form").getWidth() + "px";
$('gfx').setStyle( { width : w } );
}
Where form is an html form on my webpage and gfx the highchart graphics.
You could use an instance of the csv
module's Sniffer
class to deduce the format of a CSV file and detect whether a header row is present along with the built-in next()
function to skip over the first row only when necessary:
import csv
with open('all16.csv', 'r', newline='') as file:
has_header = csv.Sniffer().has_header(file.read(1024))
file.seek(0) # Rewind.
reader = csv.reader(file)
if has_header:
next(reader) # Skip header row.
column = 1
datatype = float
data = (datatype(row[column]) for row in reader)
least_value = min(data)
print(least_value)
Since datatype
and column
are hardcoded in your example, it would be slightly faster to process the row
like this:
data = (float(row[1]) for row in reader)
Note: the code above is for Python 3.x. For Python 2.x use the following line to open the file instead of what is shown:
with open('all16.csv', 'rb') as file:
By default, git will update execute file permissions if you change them. It will not change or track any other permissions.
If you don't see any changes when modifying execute permission, you probably have a configuration in git which ignore file mode.
Look into your project, in the .git
folder for the config
file and you should see something like this:
[core]
filemode = false
You can either change it to true
in your favorite text editor, or run:
git config core.filemode true
Then, you should be able to commit normally your files. It will only commit the permission changes.
Divide and Conquer involves three steps at each level of recursion:
Dynamic Programming involves the following four steps:
1. Characterise the structure of optimal solutions.
2. Recursively define the values of optimal solutions.
3. Compute the value of optimal solutions.
4. Construct an Optimal Solution from computed information.
For easier understanding, lets see divide and conquer as a brute force solution and its optimisation as dynamic programming.
N.B. divide and conquer algorithms with overlapping subproblems can only be optimised with dp.
I wanted to address something none of the answers have so far:
From what I've read so far, it appears that I can use Vehicles.RemoveAll() to delete an item with a particular VehicleID. As an[sic] supplementary question, is a Generic list the best repository for these objects?
Assuming VehicleID
is unique as the name suggests, a list is a terribly inefficient way to store them when you get a lot of vehicles, as removal(and other methods like Find
) is still O(n). Have a look at a HashSet<Vehicle>
instead, it has O(1) removal(and other methods) using:
int GetHashCode(Vehicle vehicle){return vehicle.VehicleID;}
int Equals(Vehicle v1, Vehicle v2){return v1.VehicleID == v2.VehicleID;}
Removing all vehicles with a specific EnquiryID still requires iterating over all elements this way, so you could consider a GetHashCode
that returns the EnquiryID
instead, depending on which operation you do more often. This has the downside of a lot of collisions if a lot of Vehicles share the same EnquiryID though.
In this case, a better alternative is to make a Dictionary<int, List<Vehicle>>
that maps EnquiryIDs to Vehicles and keep that up to date when adding/removing vehicles. Removing these vehicles from a HashSet is then an O(m) operation, where m is the number of vehicles with a specific EnquiryID.
If you want refresh the page you could use like this, but refreshing the page is usually not the best method, it better to try just update the content that you need to be updated.

@Cris sorry .This is quote MSDN Microsoft
Methodology
In this experiment, two classes will be compared. The StreamReader
and the FileStream
class will be directed to read two files of 10K and 200K in their entirety from the application directory.
StreamReader (VB.NET)
sr = New StreamReader(strFileName)
Do
line = sr.ReadLine()
Loop Until line Is Nothing
sr.Close()
FileStream (VB.NET)
Dim fs As FileStream
Dim temp As UTF8Encoding = New UTF8Encoding(True)
Dim b(1024) As Byte
fs = File.OpenRead(strFileName)
Do While fs.Read(b, 0, b.Length) > 0
temp.GetString(b, 0, b.Length)
Loop
fs.Close()
Result
FileStream
is obviously faster in this test. It takes an additional 50% more time for StreamReader
to read the small file. For the large file, it took an additional 27% of the time.
StreamReader
is specifically looking for line breaks while FileStream
does not. This will account for some of the extra time.
Recommendations
Depending on what the application needs to do with a section of data, there may be additional parsing that will require additional processing time. Consider a scenario where a file has columns of data and the rows are CR/LF
delimited. The StreamReader
would work down the line of text looking for the CR/LF
, and then the application would do additional parsing looking for a specific location of data. (Did you think String. SubString comes without a price?)
On the other hand, the FileStream
reads the data in chunks and a proactive developer could write a little more logic to use the stream to his benefit. If the needed data is in specific positions in the file, this is certainly the way to go as it keeps the memory usage down.
FileStream
is the better mechanism for speed but will take more logic.
The problem is that your REGX pattern will only match the input "0-9".
To meet your requirement (0-9999999), you should rewrite your regx pattern:
ng-pattern="/^[0-9]{1,7}$/"
My example:
HTML:
<div ng-app ng-controller="formCtrl">
<form name="myForm" ng-submit="onSubmit()">
<input type="number" ng-model="price" name="price_field"
ng-pattern="/^[0-9]{1,7}$/" required>
<span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
<span ng-show="myForm.price_field.$error.required">This field is required!</span>
<input type="submit" value="submit"/>
</form>
</div>
JS:
function formCtrl($scope){
$scope.onSubmit = function(){
alert("form submitted");
}
}
Here is a jsFiddle demo.
If you are using JavaScript to render then use escape_JavaScript("<%=render partial: partial_name, locals=>{@newval=>@oldval}%>");

using System.DirectoryServices.AccountManagement;

public Domain_Authentication(string Username, string Password, string SDomain)
{
Credentials.Username = Username;
Credentials.Password = Password;
Domain = SDomain;
}
public bool IsValid()
{
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, Domain))
{
// validate the credentials
return pc.ValidateCredentials(Credentials.Username, Credentials.Password);
}
}
}
I had a similar problem. I had installed JDK7 update 1 but couldn't use it (probably because I found a JRE6 that I deleted after installing JDK7). Uninstalling JDK7 was impossible. The solution was to add the JRE registry entries by hand.
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
"CurrentVersion"="1.7"
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7.0_01]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"
You'll have to adjust the above to your own directories and version.
If this doesn't help, there's still JavaRa http://raproducts.org/wordpress/ .
Apple recommends doing so on an actual device and has a guide on how to do this using QuickTime and iMovie on iOS and OS X: https://developer.apple.com/app-store/app-previews/imovie/Creating-App-Previews-with-iMovie.pdf
Summary:
Capture Screen Recordings with QuickTime Player
Create an App Preview with iMovie
Import Screen Recordings
Next you import the screen recording files that you captured with QuickTime Player into iMovie. In iMovie:
Create an App Preview Project
To start a new app preview project, choose File > New App Preview. A timeline appears where you can add and arrange clips to create your preview.
Removing all the events on document
:
One liner:
for (key in getEventListeners(document)) { getEventListeners(document)[key].forEach(function(c) { c.remove() }) }
Pretty version:
for (key in getEventListeners(document)) {
getEventListeners(document)[key].forEach(function(c) {
c.remove()
})
}
Thanks to Hallgrim, here is the code I ended up with:
ScreenCapture = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
bmp.GetHbitmap(),
IntPtr.Zero,
System.Windows.Int32Rect.Empty,
BitmapSizeOptions.FromWidthAndHeight(width, height));
I also ended up binding to a BitmapSource instead of a BitmapImage as in my original question
__future__
is a pseudo-module which programmers can use to enable new language features which are not compatible with the current interpreter. For example, the expression 11/4
currently evaluates to 2
. If the module in which it is executed had enabled true division by executing:
from __future__ import division
the expression 11/4
would evaluate to 2.75
. By importing the __future__
module and evaluating its variables, you can see when a new feature was first added to the language and when it will become the default:
>>> import __future__
>>> __future__.division
_Feature((2, 2, 0, 'alpha', 2), (3, 0, 0, 'alpha', 0), 8192)
that value is contained in the variable $#

thank you
routerLink
directive as used like this:
<a [routerLink]="/inbox/33/messages/44">Open Message 44</a>
is just a wrapper around imperative navigation using router
and its navigateByUrl method:
router.navigateByUrl('/inbox/33/messages/44')
as can be seen from the sources:
export class RouterLink {
...
@HostListener('click')
onClick(): boolean {
...
this.router.navigateByUrl(this.urlTree, extras);
return true;
}
So wherever you need to navigate a user to another route, just inject the router
and use navigateByUrl
method:
class MyComponent {
constructor(router: Router) {
this.router.navigateByUrl(...);
}
}
There's another method on the router that you can use - navigate:
router.navigate(['/inbox/33/messages/44'])
Using
router.navigateByUrl
is similar to changing the location bar directly–we are providing the “whole” new URL. Whereasrouter.navigate
creates a new URL by applying an array of passed-in commands, a patch, to the current URL.To see the difference clearly, imagine that the current URL is
'/inbox/11/messages/22(popup:compose)'
.With this URL, calling
router.navigateByUrl('/inbox/33/messages/44')
will result in'/inbox/33/messages/44'
. But calling it withrouter.navigate(['/inbox/33/messages/44'])
will result in'/inbox/33/messages/44(popup:compose)'
.
Read more in the official docs.
PS: This is not an answer but just a supplement to the above answers.
Just for the future reference, I have included a good example that might help us to clear our doubt:
Try the following. In this example I shall create a file selector which can be used to select a file and then I shall try to retrieve the name of the file that I selected: The HTML code is below:
<html>
<body>
<form action="#" method="post">
<input id ="myfile" type="file"/>
</form>
<script type="text/javascript" src="jquery.js"> </script>
<script type="text/javascript" src="code.js"> </script>
</body>
</html>
The code.js file contains the following jQuery code. Try to use both of the jQuery code snippets one by one and see the output.
jQuery code with attr('value'):
$('#myfile').change(function(){
alert($(this).attr('value'));
$('#mybutton').removeAttr('disabled');
});
jQuery code with val():
$('#myfile').change(function(){
alert($(this).val());
$('#mybutton').removeAttr('disabled');
});
Output:
The output of jQuery code with attr('value') will be 'undefined'. The output of jQuery code with val() will the file name that you selected.
Explanation: Now you may understand easily what the top answers wanted to convey. The output of jQuery code with attr('value') will be 'undefined' because initially there was no file selected so the value is undefined. It is better to use val() because it gets the current value.
In order to see why the undefined value is returned try this code in your HTML and you'll see that now the attr.('value') returns 'test' always, because the value is 'test' and previously it was undefined.
<input id ="myfile" type="file" value='test'/>
I hope it was useful to you.
I have streamlined the answer of @Quirliom above into functions that can be used:
private static boolean hasLength(CharSequence data) {
if (String.valueOf(data).length() >= 8) return true;
else return false;
}
private static boolean hasSymbol(CharSequence data) {
String password = String.valueOf(data);
boolean hasSpecial = !password.matches("[A-Za-z0-9 ]*");
return hasSpecial;
}
private static boolean hasUpperCase(CharSequence data) {
String password = String.valueOf(data);
boolean hasUppercase = !password.equals(password.toLowerCase());
return hasUppercase;
}
private static boolean hasLowerCase(CharSequence data) {
String password = String.valueOf(data);
boolean hasLowercase = !password.equals(password.toUpperCase());
return hasLowercase;
}
Just an update to the 'no exceptions on resources' problem as pointed to by @jarmod (do please feel free to update your answer if below seems applicable)
I have tested the below code and it runs fine. It uses 'resources' for doing things, but catches the client.exceptions
- although it 'looks' somewhat wrong... it tests good, the exception classes are showing and matching when looked into using debugger at exception time...
It may not be applicable to all resources and clients, but works for data folders (aka s3 buckets).
lab_session = boto3.Session()
c = lab_session.client('s3') #this client is only for exception catching
try:
b = s3.Bucket(bucket)
b.delete()
except c.exceptions.NoSuchBucket as e:
#ignoring no such bucket exceptions
logger.debug("Failed deleting bucket. Continuing. {}".format(e))
except Exception as e:
#logging all the others as warning
logger.warning("Failed deleting bucket. Continuing. {}".format(e))
Hope this helps...

In addition if one uses static keyword on a variable like this example:

Add labels to each argument in your plot call corresponding to the series it is graphing, i.e. label = "series 1"
Then simply add Pyplot.legend()
to the bottom of your script and the legend will display these labels.
Depending on the boost version libboost-system comes with the -mt suffix which should indicate the libraries multithreading capability.
So if -lboost_system
cannot be found by the linker try -lboost_system-mt

It's really not an 'either/or' situation. AJAX stands for Asynchronous JavaScript and XML, and JQuery is a JavaScript library that takes the pain out of writing common JavaScript routines.
It's the difference between a thing (jQuery) and a process (AJAX). To compare them would be to compare apples and oranges.
After you installed docker, created 'docker' group and added user to it, edit docker service unit file:
sudo nano /usr/lib/systemd/system/docker.service
Add two lines into the section [Service]:
SupplementaryGroups=docker

Save the file (Ctrl-X, y, Enter)
Run and enable the Docker service:
sudo systemctl daemon-reload

Or
input {

}
Hope this helps you.
Parse the string into an integer using parseInt

Agree with neubert about the DECLARE statements, this will fix syntax error. But I would suggest you to avoid using openning cursors, they may be slow.
For your task: use INSERT...SELECT statement which will help you to copy data from one table to another using only one query.

I used @LiorH's example and expanded it to:
@XmlRootElement(name="List")
public class JaxbList<T>{
protected List<T> list;
public JaxbList(){}
public JaxbList(List<T> list){
this.list=list;
}
@XmlElement(name="Item")
public List<T> getList(){
return list;
}
}
Note, that it uses generics so you can use it with other classes than String. Now, the application code is simply:
@GET
@Path("/test2")
public JaxbList test2(){
List list=new Vector();
list.add("a");
list.add("b");
return new JaxbList(list);
}
Why doesn't this simple class exist in the JAXB package? Anyone see anything like it elsewhere?
PyInstaller will create a single .exe file with no dependencies; use the --onefile
option. It does this by packing all the needed shared libs into the executable, and unpacking them before it runs, just as you describe (EDIT: py2exe also has this feature, see minty's answer)
I use the version of PyInstaller from svn, since the latest release (1.3) is somewhat outdated. It's been working really well for an app which depends on PyQt, PyQwt, numpy, scipy and a few more.

I took it from here: https://www.drupal.org/node/1129120
Single line complete removal on hide ( ES6 )
$("#myModal").on('hidden.bs.modal', (e)=>e.currentTarget.remove());
Another design pattern that I have seen involves using blocks, which is especially useful when a method is being run asynchronously.
Say we have the following error codes defined:
typedef NS_ENUM(NSInteger, MyErrorCodes) {
MyErrorCodesEmptyString = 500,
MyErrorCodesInvalidURL,
MyErrorCodesUnableToReachHost,
};
You would define your method that can raise an error like so:
- (void)getContentsOfURL:(NSString *)path success:(void(^)(NSString *html))success failure:(void(^)(NSError *error))failure {
if (path.length == 0) {
if (failure) {
failure([NSError errorWithDomain:@"com.example" code:MyErrorCodesEmptyString userInfo:nil]);
}
return;
}
NSString *htmlContents = @"";
// Exercise for the reader: get the contents at that URL or raise another error.
if (success) {
success(htmlContents);
}
}
And then when you call it, you don't need to worry about declaring the NSError object (code completion will do it for you), or checking the returning value. You can just supply two blocks: one that will get called when there is an exception, and one that gets called when it succeeds:
[self getContentsOfURL:@"http://google.com" success:^(NSString *html) {
NSLog(@"Contents: %@", html);
} failure:^(NSError *error) {
NSLog(@"Failed to get contents: %@", error);
if (error.code == MyErrorCodesEmptyString) { // make sure to check the domain too
NSLog(@"You must provide a non-empty string");
}
}];
/<b>(.*?)<\/b>/g
Add g
(global) flag after:
/<b>(.*?)<\/b>/g.exec(str)
//^-----here it is
However if you want to get all matched elements, then you need something like this:
var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";
var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
return val.replace(/<\/?b>/g,'');

If an element has attributes, regexp will be:
/<b [^>]+>(.*?)<\/b>/g.exec(str)
Further to @T.J. Crowder 's answer, I've added a recursive outer loop that allows one to iterate through all the scripts in an array and then execute a function once all the scripts are loaded:
loadList([array of scripts], 0, function(){// do your post-scriptload stuff})
function loadList(list, i, callback)
{
{
loadScript(list[i], function()
{
if(i < list.length-1)
{
loadList(list, i+1, callback);
}
else
{
callback();
}
})
}
}
Of course you can make a wrapper to get rid of the '0' if you like:
function prettyLoadList(list, callback)
{
loadList(list, 0, callback);
}
Nice work @T.J. Crowder - I was cringing at the 'just add a couple seconds delay before running the callback' I saw in other threads.
setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").
From the command line, you can type
python setup.py --help
...to get a list of commands. What you are looking to do is...
python setup.py install
As of SLF4J 1.6.0, in the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will presume that the user wants the last argument to be treated as an exception and not a simple parameter. See also the relevant FAQ entry.
So, writing (in SLF4J version 1.7.x and later)
logger.error("one two three: {} {} {}", "a", "b",
"c", new Exception("something went wrong"));
or writing (in SLF4J version 1.6.x)
logger.error("one two three: {} {} {}", new Object[] {"a", "b",
"c", new Exception("something went wrong")});
will yield
one two three: a b c
java.lang.Exception: something went wrong
at Example.main(Example.java:13)
at java.lang.reflect.Method.invoke(Method.java:597)
at ...
The exact output will depend on the underlying framework (e.g. logback, log4j, etc) as well on how the underlying framework is configured. However, if the last parameter is an exception it will be interpreted as such regardless of the underlying framework.
My recommendation is to solve problems that you're interested in, writing code that might be useful to you.
Java is a huge box. It's got a lot of computer science inside: graphics, scientific computing, relational databases, user interfaces for desktop and web, messaging and queuing, multi-threading, security, and more. Each area has their own "beginner problem". Which one do you mean?
How do you define "beginner problem"? Maybe you're having trouble because you aren't narrowing your search enough.
If your imagination is lacking, your best bet is to Google something like "java beginner practice problems" and investigate what you get back.
Or start with Sun's on-line Java tutorial and work you way all the way through it. You'll know a fair amount about Java when you're done.
I found a shorter and very straightforward solution which works seamlessly, and with authentication as well, using express-http-proxy
:
const url = require('url');
const proxy = require('express-http-proxy');
// New hostname+path as specified by question:
const apiProxy = proxy('other_domain.com:3000/BLABLA', {
proxyReqPathResolver: req => url.parse(req.baseUrl).path
});
And then simply:
app.use('/api/*', apiProxy);
Note: as mentioned by @MaxPRafferty, use req.originalUrl
in place of baseUrl
to preserve the querystring:
forwardPath: req => url.parse(req.baseUrl).path
Update: As mentioned by Andrew (thank you!), there's a ready-made solution using the same principle:
npm i --save http-proxy-middleware
And then:
const proxy = require('http-proxy-middleware')
var apiProxy = proxy('/api', {target: 'http://www.example.org/api'});
app.use(apiProxy)
Documentation: http-proxy-middleware on Github
I know I'm late to join this party, but I hope this helps someone.
Maybe something like this:
First some test data:
DECLARE @tbl TABLE(Column1 VARCHAR(100))
INSERT INTO @tbl
SELECT '1/1' UNION ALL
SELECT '1/20' UNION ALL
SELECT '1/2'
Then like this:
SELECT
SUBSTRING(tbl.Column1,CHARINDEX('/',tbl.Column1)+1,LEN(tbl.Column1))
FROM
@tbl AS tbl
What is the portable way to annotate a byte[] property?
It depends on what you want. JPA can persist a non annotated byte[]
. From the JPA 2.0 spec:
11.1.6 Basic Annotation
The
Basic
annotation is the simplest type of mapping to a database column. TheBasic
annotation can be applied to a persistent property or instance variable of any of the following types: Java primitive, types, wrappers of the primitive types,java.lang.String
,java.math.BigInteger
,java.math.BigDecimal
,java.util.Date
,java.util.Calendar
,java.sql.Date
,java.sql.Time
,java.sql.Timestamp
,byte[]
,Byte[]
,char[]
,Character[]
, enums, and any other type that implementsSerializable
. As described in Section 2.8, the use of theBasic
annotation is optional for persistent fields and properties of these types. If the Basic annotation is not specified for such a field or property, the default values of the Basic annotation will apply.
And Hibernate will map a it "by default" to a SQL VARBINARY
(or a SQL LONGVARBINARY
depending on the Column
size?) that PostgreSQL handles with a bytea
.
But if you want the byte[]
to be stored in a Large Object, you should use a @Lob
. From the spec:
11.1.24 Lob Annotation
A
Lob
annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use theLob
annotation when mapping to a databaseLob
type. TheLob
annotation may be used in conjunction with the Basic annotation or with theElementCollection
annotation when the element collection value is of basic type. ALob
may be either a binary or character type. TheLob
type is inferred from the type of the persistent field or property and, except for string and character types, defaults to Blob.
And Hibernate will map it to a SQL BLOB
that PostgreSQL handles with a oid
.
Is this fixed in some recent version of hibernate?
Well, the problem is that I don't know what the problem is exactly. But I can at least say that nothing has changed since 3.5.0-Beta-2 (which is where a changed has been introduced)in the 3.5.x branch.
But my understanding of issues like HHH-4876, HHH-4617 and of PostgreSQL and BLOBs (mentioned in the javadoc of the PostgreSQLDialect
) is that you are supposed to set the following property
hibernate.jdbc.use_streams_for_binary=false
if you want to use oid
i.e. byte[]
with @Lob
(which is my understanding since VARBINARY
is not what you want with Oracle). Did you try this?
As an alternative, HHH-4876 suggests using the deprecated PrimitiveByteArrayBlobType
to get the old behavior (pre Hibernate 3.5).

You can achieve what you want, but with a different syntax. You can use a "finally" block after the try/except. Doing this way, python will execute the block of code regardless the exception was thrown, or not.
Like this:
try:
do_smth1()
except:
pass
finally:
do_smth2()
But, if you want to execute do_smth2() only if the exception was not thrown, use a "else" block:
try:
do_smth1()
except:
pass
else:
do_smth2()
You can mix them too, in a try/except/else/finally clause. Have fun!
This counts the rows of the inner query:
select count(*) from (
select count(SID)
from Test
where Date = '2012-12-10'
group by SID
) t
However, in this case the effect of that is the same as this:
select count(distinct SID) from Test where Date = '2012-12-10'

This is my take at it. Combined from the answers and MSDN
public static TEnum ParseToEnum<TEnum>(this string text) where TEnum : struct, IConvertible, IComparable, IFormattable
{
if (string.IsNullOrEmpty(text) || !typeof(TEnum).IsEnum)
throw new ArgumentException("TEnum must be an Enum type");
try
{
var enumValue = (TEnum)Enum.Parse(typeof(TEnum), text.Trim(), true);
return enumValue;
}
catch (Exception)
{
throw new ArgumentException(string.Format("{0} is not a member of the {1} enumeration.", text, typeof(TEnum).Name));
}
}
Messing around with the same answers:
$ git config --global alias.find '!git log --color -p -S '
Now you can do
$ git find <whatever>
or
$ git find <whatever> --all
$ git find <whatever> master develop
IIRC, something like:
set tabstop=2 shiftwidth=2 expandtab
should do the trick. If you already have tabs, then follow it up with a nice global RE to replace them with double spaces.
If you already have tabs you want to replace,
:retab
There is a new way using transforms. Apply this to the element to centre. It nudges down by half the container height and then 'corrects' by half the element height.
position: relative;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
It works most of the time. I did have a problem where a div
was in a div
in a li
. The list item had a height set and the outer div
s made up 3 columns (Foundation). The 2nd and 3rd column divs contained images, and they centered just fine with this technique, however the heading in the first column needed a wrapping div with an explicit height set.
Now, does anyone know if the CSS people are working on a way to align stuff, like, easily? Seeing that its 2014 and even some of my friends are regularly using the internet, I wondered if anyone had considered that centering would be a useful styling feature yet. Just us then?
please try to do
make clean
(instead of make
), then
make
again.
You can write extention method:
public static async Task<Tout> ReadAsAsync<Tout>(this System.Net.Http.HttpContent content) {
return Newtonsoft.Json.JsonConvert.DeserializeObject<Tout>(await content.ReadAsStringAsync());
}
<a class="btn btn-large btn-success" id="fire" href="http://twitter.github.io/bootstrap/examples/marketing-narrow.html#">Send Email</a>

Run the application in Emulator after you insert some data, just close the application.
Now open the DDMS or Android Monitor and select your emulator, on the right side you can see the File Explorer, look for Data folder in it and look for your application package that you have created, in that you can find the shared preference file open it , you can see the XML file, click it and click the pull a file from the device button in the top right corner.
The XML file will be saved in your desired location, then you can open it using any editor like notepad++ and can view the data you have entered.
EditText dummy = ...
// android.view.View.OnFocusChangeListener
dummy.setOnFocusChangeListener(new OnFocusChangeListener(){
public void onFocusChange(View v, boolean hasFocus){

}
});
Definition:
public static string ConvertByteToString(this byte[] source)
{
return source != null ? System.Text.Encoding.UTF8.GetString(source) : null;
}
Using:
string result = input.ConvertByteToString();
Arrays can't be passed as function parameters by value in C.
You can put the array in a struct:
typedef struct type24 {
char byte[3];
} type24;
and then pass that by value, but of course then it's less convenient to use: x.byte[0]
instead of x[0]
.
Your function type24_to_int32(char value[3])
actually passes by pointer, not by value. It's exactly equivalent to type24_to_int32(char *value)
, and the 3
is ignored.
If you're happy passing by pointer, you could stick with the array and do:
type24_to_int32(const type24 *value);
This will pass a pointer-to-array, not pointer-to-first-element, so you use it as:
(*value)[0]
I'm not sure that's really a gain, since if you accidentally write value[1]
then something stupid happens.
This should work:
cat "$API" >> "$CONFIG"
You need to use the >>
operator to append to a file. Redirecting with >
causes the file to be overwritten. (truncated).
In swift4 I have always used string.count
till today I have found that
string.endIndex.encodedOffset
is the better substitution because it is faster - for 50 000 characters string is about 6 time faster than .count
. The .count
depends on the string length but .endIndex.encodedOffset
doesn't.
But there is one NO. It is not good for strings with emojis, it will give wrong result, so only .count
is correct.
ord()
will not work because your end string is two characters long.
Returns the ASCII value of the first character of string.
From my testing, you need to check that the end
string doesn't get "stepped over". The perl-style character incrementation is a cool method, but it is a single-stepping method. For this reason, an inner loop helps it along when necessary. This is actually not a bother, in fact, it is useful because we need to check if the loop(s) should be broken on each single step.
Code: (Demo)
function excelCols($letter,$end,$step=1){ // function doesn't check that $end is "later" than $letter
if($step==0)return []; // prevent infinite loop
do{
$letters[]=$letter; // store letter
for($x=0; $x<$step; ++$x){ // increment in accordance with $step declaration
if($letter===$end)break(2); // break if end is "stepped on"
++$letter;
}
}while(true);
return $letters;
}
echo implode(' ',excelCols('A','JJ',4));
echo "\n --- \n";
echo implode(' ',excelCols('A','BB',3));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',1));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',3));

Ruby is slower than C++ at a number of easily measurable tasks (e.g., doing code that is heavily dependent on floating point). This is not very surprising, but enough justification for some people to say that “Ruby is Slow” without qualification. They don't count the fact that it is far easier and safer to write Ruby code than C++.
The best fix is to use targeted modules written in another language (e.g., C, C++, Fortran) in your Ruby code. Those can do the heavy lifting and your scripts can focus on higher level coordination issues.

You need to add the "global" flag to your regex:
s.replace(new RegExp("[0-9]", "g"), "X")
or, perhaps prettier, using the built-in literal regexp syntax:
.replace(/[0-9]/g, "X")
This might not be an ethical and preferred solution but it helps in environments where you can't access the console to kill the job using yarn application command.
Steps are
Go to application master page of spark job. Click on the jobs section. Click on the active job's active stage. You will see "kill" button right next to the active stage.
This works if the succeeding stages are dependent on the currently running stage. Though it marks job as " Killed By User"
You can try this:
$scope.child = {} //declare it in parent controller (scope)
then in child controller (scope) add:
var parentScope = $scope.$parent;
parentScope.child = $scope;
Now the parent has access to the child's scope.
In your TS Definition file, e.g. typings.d.ts`, you can add this line:
declare module "*.json" {
const value: any;
export default value;
}
Then add this in your typescript(.ts) file:-
import * as data from './colors.json';
const word = (<any>data).name;
Curiously enough, the accepted answer does not actually answer the question directly. The question asks about using sed to replace a string, but the answer seems to presuppose knowledge of how to convert an arbitrary string into a regex.
Many programming language libraries have a function to perform such a transformation, e.g.
python: re.escape(STRING)
ruby: Regexp.escape(STRING)
java: Pattern.quote(STRING)
But how to do it on the command line?
Since this is a sed-oriented question, one approach would be to use sed itself:
sed 's/\([\[/({.*+^$?]\)/\\\1/g'
So given an arbitrary string $STRING we could write something like:
re=$(sed 's/\([\[({.*+^$?]\)/\\\1/g' <<< "$STRING")
sed "/$re/d" FILE
or as a one-liner:
sed "/$(sed 's/\([\[/({.*+^$?]\)/\\\1/g' <<< "$STRING")/d"
with variations as described elsewhere on this page.
I used simply string baseDir = Environment.CurrentDirectory;
and its work for me.
Good Luck
Edit:
I used to delete this type of mistake but i prefer to edit it because i think the minus point on this answer help people to know about wrong way. :) I understood the above solution is not useful and i changed it to string appBaseDir = System.AppDomain.CurrentDomain.BaseDirectory;
Other ways to get it are:
1. string baseDir =
System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
2. String exePath = System.Environment.GetCommandLineArgs()[0];
3. string appBaseDir = System.IO.Path.GetDirectoryName
(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
Good Luck
This is a follow-up to user106826's link to Namespace.js. It seems the project moved to GitHub. It is now smith/namespacedotjs.
I have been using this simple JavaScript helper for my tiny project and so far it seems to be light yet versatile enough to handle namespacing and loading modules/classes. It would be great if it would allow me to import a package into a namespace of my choice, not just the global namespace... sigh, but that's besides the point.
It allows you to declare the namespace then define objects/modules in that namespace:
Namespace('my.awesome.package');
my.awesome.package.WildClass = {};
Another option is to declare the namespace and its contents at once:
Namespace('my.awesome.package', {
SuperDuperClass: {
saveTheDay: function() {
alert('You are welcome.');
}
}
});
For more usage examples, look at the example.js file in the source.

To match the title of this question, the value of the id
attribute is:
var myId = $(this).attr('id');
alert( myId );
BUT, of course, the element must already have the id element defined, as:
<option id="opt7" class='select_continent' value='7'>Antarctica</option>
In the OP post, this was not the case.
Note that plain js is faster (in this case):
var myId = this.id
alert( myId );

1) The function returns a cell for a table view yes? So, the returned object is of type UITableViewCell
. These are the objects that you see in the table's rows. This function basically returns a cell, for a table view.
But you might ask, how the function would know what cell to return for what row, which is answered in the 2nd question
2)NSIndexPath
is essentially two things-
Because your table might be divided to many sections and each with its own rows, this NSIndexPath
will help you identify precisely which section and which row. They are both integers. If you're a beginner, I would say try with just one section.

class. I strongly recommend this because it Apple has some code written for you to easily implement the functions that can describe a table. Anyway, if you choose to implement this protocol yourself, you need to create a UITableViewCell
object and return it for whatever row. Have a look at its class reference to understand re-usablity because the cells that are displayed in the table view are reused again and again(this is a very efficient design btw).
As for when you have two table views, look at the method. The table view is passed to it, so you should not have a problem with respect to that.
right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.
This is the best answer to solve the problem
Thanks all for your help! Finally I used JQuery/AJAX as you suggested, passing the parameter using model.
So, in JS:
$('#divPoints').load('/Schedule/UpdatePoints', UpdatePointsAction);
var points= $('#newpoints').val();
$element.find('PointsDiv').html("You have" + points+ " points");
In Controller:
var model = _newPoints;
return PartialView(model);
In View
<div id="divPoints"></div>
@Html.Hidden("newpoints", Model)
Using the "Developer Command Prompt for Visual Studio 20XX" instead of "cmd" will set the path for msbuild automatically without having to add it to your environment variables.
You need to use a "struct" in situations where you want to explicitly specify memory layout using the StructLayoutAttribute - typically for PInvoke.
Edit: Comment points out that you can use class or struct with StructLayoutAttribute and that is certainly true. In practice, you would typically use a struct - it is allocated on the stack vs the heap which makes sense if you are just passing an argument to an unmanaged method call.
Seems user has declined the permission and app tries to write to external disk, causing error.

Also, if you want to rotate an ImageView by 180 degrees vertically or horizontally, you can use scaleY
or scaleX
properties and set them to -1f
. Here is a Kotlin example:
imageView.scaleY = -1f
imageView.scaleX = -1f
1f
value is used to return an ImageView to its normal state:
imageView.scaleY = 1f
imageView.scaleX = 1f
const is not supported by ECMAScript. So after you specify strict mode, you get syntax error. You need to use var instead of const if you want your code to be compatible with all browsers. I know, not the ideal solution, but it is what it is. There are ways to create read-only properties in JavaScript (see Can Read-Only Properties be Implemented in Pure JavaScript?) but I think it might be overkill depending on your scenario.
Below is browser compatibility note from MDN:
Browser compatibility
The current implementation of const is a Mozilla-specific extension and is not part of ECMAScript 5. It is supported in Firefox & Chrome (V8). As of Safari 5.1.7 and Opera 12.00, if you define a variable with const in these browsers, you can still change its value later. It is not supported in Internet Explorer 6-10, but is included in Internet Explorer 11. The const keyword currently declares the constant in the function scope (like variables declared with var).
Firefox, at least since version 13, throws a TypeError if you redeclare a constant. None of the major browsers produce any notices or errors if you assign another value to a constant. The return value of such an operation is that of the new value assigned, but the reassignment is unsuccessful only in Firefox and Chrome (at least since version 20).
const is going to be defined by ECMAScript 6, but with different semantics. Similar to variables declared with the let statement, constants declared with const will be block-scoped.
Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)
The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.
@if (@CodeSection == @Batch) @then
@echo off
rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"
rem Start the other program in the same Window
start "" /B cmd
%SendKeys% "echo off{ENTER}"
set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"
set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"
set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"
%SendKeys% "exit{ENTER}"
goto :EOF
@end
// JScript section
var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));
For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx
For example:
LEFT ARROW {LEFT}
RIGHT ARROW {RIGHT}

Just write simple template:
template<typename T>
const char* getClassName(T) {
return typeid(T).name();
}
struct A {} a;
void main() {
std::cout << getClassName(a);
}
Let me try to make it simple, suppose URL of the site is http://example.com/ and let's suppose you need to sign up by filling username and password, so we go to the login page say http://example.com/login.php now and view it's source code and search for the action URL it will be in form tag something like
<form name="loginform" method="post" action="userinfo.php">
now take userinfo.php to make absolute URL which will be 'http://example.com/userinfo.php', now run a simple python script
import requests
url = 'http://example.com/userinfo.php'
values = {'username': 'user',
'password': 'pass'}
r = requests.post(url, data=values)
print r.content
I Hope that this helps someone somewhere someday.
Beware the Authenticity Token mechanism can result in race conditions if you have multiple, concurrent requests from the same client. In this situation your server can generate multiple authenticity tokens when there should only be one, and the client receiving the earlier token in a form will fail on it's next request because the session cookie token has been overwritten. There is a write up on this problem and a not entirely trivial solution here: http://www.paulbutcher.com/2007/05/race-conditions-in-rails-sessions-and-how-to-fix-them/
I Use this query:
select floor(RAND() * (SELECT MAX(key) FROM table)) from table limit 10
query time:0.016s
What I did to solve the problem was:
git pull origin [branch]
git push origin [branch]
Also make sure that you are pointing to the right branch by running:
git remote set-url origin [url]
Inspired by Steve answer, I wrote simple function that toggles between vertical and horizontal splits for all windows in current tab. You can bind it to mapping like in the last line below.
function! ToggleWindowHorizontalVerticalSplit()
if !exists('t:splitType')
let t:splitType = 'vertical'
endif
if t:splitType == 'vertical' " is vertical switch to horizontal
windo wincmd K
let t:splitType = 'horizontal'
else " is horizontal switch to vertical
windo wincmd H
let t:splitType = 'vertical'
endif
endfunction
nnoremap <silent> <leader>wt :call ToggleWindowHorizontalVerticalSplit()<cr>
It will work when adding space between id and class identifier
$("#countery .save")...
For synchronous approach
const fs = require('fs')
fs.writeFileSync('file.json', JSON.stringify(jsonVariable));
It sounds like probability density estimation problem to me.
from scipy.stats import gaussian_kde
occurences = [0,0,0,0,..,1,1,1,1,...,2,2,2,2,...,47]
values = range(0,48)
kde = gaussian_kde(map(float, occurences))
p = kde(values)
p = p/sum(p)
print "P(x>=1) = %f" % sum(p[1:])
Also see http://jpktd.blogspot.com/2009/03/using-gaussian-kernel-density.html.
That's simply not the way you use prepared statements.
It is perfectly okay to insert one row per query because you can execute one prepared statement multiple times with different parameters. In fact that is one of the greatest advantages as it allows you to insert you a great number of rows in an efficient, secure and comfortable manner.
So it maybe possible to implement the scheme you proposing, at least for a fixed number of rows, but it is almost guaranteed that this is not really what you want.
I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.
The Error is here
lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1
wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this
lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1
Similarly
wsPOR.Range("A2:G" & lastrow).Select
should be
wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select
There are at least five different ways to rename specific columns in pandas, and I have listed them below along with links to the original answers. I also timed these methods and found them to perform about the same (though YMMV depending on your data set and scenario). The test case below is to rename columns A
M
N
Z
to A2
M2
N2
Z2
in a dataframe with columns A
to Z
containing a million rows.
# Import required modules
import numpy as np
import pandas as pd
import timeit
# Create sample data
df = pd.DataFrame(np.random.randint(0,9999,size=(1000000, 26)), columns=list('ABCDEFGHIJKLMNOPQRSTUVWXYZ'))
# Standard way - https://stackoverflow.com/a/19758398/452587
def method_1():
df_renamed = df.rename(columns={'A': 'A2', 'M': 'M2', 'N': 'N2', 'Z': 'Z2'})
# Lambda function - https://stackoverflow.com/a/16770353/452587
def method_2():
df_renamed = df.rename(columns=lambda x: x + '2' if x in ['A', 'M', 'N', 'Z'] else x)
# Mapping function - https://stackoverflow.com/a/19758398/452587
def rename_some(x):
if x=='A' or x=='M' or x=='N' or x=='Z':
return x + '2'
return x
def method_3():
df_renamed = df.rename(columns=rename_some)
# Dictionary comprehension - https://stackoverflow.com/a/58143182/452587
def method_4():
df_renamed = df.rename(columns={col: col + '2' for col in df.columns[
np.asarray([i for i, col in enumerate(df.columns) if 'A' in col or 'M' in col or 'N' in col or 'Z' in col])
]})
# Dictionary comprehension - https://stackoverflow.com/a/38101084/452587
def method_5():
df_renamed = df.rename(columns=dict(zip(df[['A', 'M', 'N', 'Z']], ['A2', 'M2', 'N2', 'Z2'])))
print('Method 1:', timeit.timeit(method_1, number=10))
print('Method 2:', timeit.timeit(method_2, number=10))
print('Method 3:', timeit.timeit(method_3, number=10))
print('Method 4:', timeit.timeit(method_4, number=10))
print('Method 5:', timeit.timeit(method_5, number=10))
Output:

Use the method that is most intuitive to you and easiest for you to implement in your application.
// wrap it in jQuery, now it's a collection
var $elements = $(someHTML);
// append to the DOM
$("#myDiv").append($elements);
// do stuff, using the initial reference
$elements.effects("highlight", {}, 2000);
Backup a single table with its data from a database in sql server 2008

This works without any quotations.
You first must install python. Mac comes with python 2.7 installed to install Python 3 you can follow this tutorial: http://docs.python-guide.org/en/latest/starting/install3/osx/.
To run the program you can then copy and paste in this code:
python /Users/luca/Documents/python/gameover.py
Or you can go to the directory of the file with cd
followed by the folder. When you are in the folder you can then python YourFile.py
.
The rates that were quoted above are what you would expect to pay US developers; however, I do know some people who have been able to get their apps built for as little as $4,000 by using offshore developers.
Here is a blog post from a group that did this: http://www.lolerapps.com/why-outsourcing-iphone-apps-was-a-no-brainer-for-us
Also, Carla White wrote a fantastic eBook about the process she used to outsource her app called "Inside Secrets to an iPhone App". She talks about how she got a great deal because she was willing to work with a team that was still learning iPhone app development.
So, there are alternatives to the higher price developers discussed above.
If your console (like your standard ubuntu console) understands ANSI color codes, you can use those.
Here an example:

The shortest answer would probably be "definition is execution", therefore the whole argument makes no strict sense. As a more contrived example, you may cite this:
def a(): return []
def b(x=a()):
print x
Hopefully it's enough to show that not executing the default argument expressions at the execution time of the def
statement isn't easy or doesn't make sense, or both.
I agree it's a gotcha when you try to use default constructors, though.
You need to add this in your web.config
<system.net>
<defaultProxy>
<proxy bypassonlocal="False" usesystemdefault="True" proxyaddress="http://127.0.0.1:8888" />
</defaultProxy>
</system.net>
That's all, but don't forget to remove the web.config lines after closing the fiddler, because if you don't it will make an error.

If someone is still facing the issue on their local machine(Ubuntu) then try below command:

Notepad++ has a powerful regex engine, capable to search and replace patterns at will.
In your scenario:
Click the menu item Search\Replace...
Fill the 'Find what' field with the search pattern:
^(\d{4})\s+(\w{3})\s+(\w{3})$
Fill the replace pattern:
Insert into tbl (\1, \2) where clm = \3
Click the Replace All
button.
And that's it.
As a supplement to the question and above answers there is also an important difference between plt.subplots()
and plt.subplot()
, notice the missing 's'
at the end.
One can use plt.subplots()
to make all their subplots at once and it returns the figure and axes (plural of axis) of the subplots as a tuple. A figure can be understood as a canvas where you paint your sketch.
# create a subplot with 2 rows and 1 columns
fig, ax = plt.subplots(2,1)
Whereas, you can use plt.subplot()
if you want to add the subplots separately. It returns only the axis of one subplot.
fig = plt.figure() # create the canvas for plotting
ax1 = plt.subplot(2,1,1)
# (2,1,1) indicates total number of rows, columns, and figure number respectively
ax2 = plt.subplot(2,1,2)
However, plt.subplots()
is preferred because it gives you easier options to directly customize your whole figure
# for example, sharing x-axis, y-axis for all subplots can be specified at once
fig, ax = plt.subplots(2,2, sharex=True, sharey=True)
whereas, with plt.subplot()
, one will have to specify individually for each axis which can become cumbersome.
INSERT INTO Table2 SELECT DISTINCT ID,Data = STUFF((SELECT ', ' + AA.Data FROM Table1 AS AA WHERE AA.ID = BB.ID FOR XML PATH(''), TYPE).value('.','nvarchar(max)'), 1, 2, '') FROM Table1 AS BB
GROUP BY ID,Data
ORDER BY ID;
I'm not sure if this would be a common mistake, but if you do something like:
$var = 'value' .= 'value2';
this will also produce the same error
Can't use method return value in write context
You can't have an =
and a .=
in the same statement. You can use one or the other, but not both.
Note, I understand this is unrelated to the actual code in the question, however this question is the top result when searching for the error message, so I wanted to post it here for completeness.
another language meta tag is og:locale and you can define og:locale meta tag for social media

This is unrelated to UTF-8/16 (in general, although it does convert to UTF16 and the BE/LE part can be set w/ a single line), yet below is the fastest way to convert String to byte[]. For instance: good exactly for the case provided (hash code). String.getBytes(enc) is relatively slow.
static byte[] toBytes(String s){
byte[] b=new byte[s.length()*2];
ByteBuffer.wrap(b).asCharBuffer().put(s);
return b;
}
As of Java 8, some local variable name information is available through reflection. See the "Update" section below.
Complete information is often stored in class files. One compile-time optimization is to remove it, saving space (and providing some obsfuscation). However, when it is is present, each method has a local variable table attribute that lists the type and name of local variables, and the range of instructions where they are in scope.
Perhaps a byte-code engineering library like ASM would allow you to inspect this information at runtime. The only reasonable place I can think of for needing this information is in a development tool, and so byte-code engineering is likely to be useful for other purposes too.
Update: Limited support for this was added to Java 8. Parameter (a special class of local variable) names are now available via reflection. Among other purposes, this can help to replace @ParameterName
annotations used by dependency injection containers.
You need:
#include <string.h> /* memset */
#include <unistd.h> /* close */
in your code.

Found the solution myself in the end. The problem was not with the LinearLayout
, but with the ScrollView
(seems weird, considering the fact that the ScrollView
was expanding, while the LinearLayout
wasn't).
The solution was to use android:fillViewport="true"
on the ScrollView
.
