There are some nice answers on this question. I’ll try to add a more broad answer, namely about what these kinds of lines/headers/trailers are about in current practice. Not so much about the sign-off header in particular (it’s not the only one).
Headers or trailers (?1) like “sign-off” (?2) is, in current
practice in projects like Git and Linux, effectively structured metadata
for the commit. These are all appended to the end of the commit message,
after the “free form” (unstructured) part of the body of the message.
These are token–value (or key–value) pairs typically delimited by a
colon and a space (:?
).
Like I mentioned, “sign-off” is not the only trailer in current practice. See for example this commit, which has to do with “Dirty Cow”:
mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
This is an ancient bug that was actually attempted to be fixed once
(badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
get_user_pages() race for write access") but that was then undone due to
problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").
In the meantime, the s390 situation has long been fixed, and we can now
fix it by checking the pte_dirty() bit properly (and do it better). The
s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
software dirty bits") which made it into v3.9. Earlier kernels will
have to look at the page state itself.
Also, the VM has become more scalable, and what used a purely
theoretical race back then has become easier to trigger.
To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
we already did a COW" rather than play racy games with FOLL_WRITE that
is very fundamental, and then use the pte dirty flag to validate that
the FOLL_COW flag is still valid.

In addition to the “sign-off” trailer in the above, there is:
Other projects, like for example Gerrit, have their own headers and associated meaning for them.
See: https://git.wiki.kernel.org/index.php/CommitMessageConventions
It is my impression that, although the initial motivation for this particular metadata was some legal issues (judging by the other answers), the practice of such metadata has progressed beyond just dealing with the case of forming a chain of authorship.

[?2]: These are also sometimes called “s-o-b” (initials), it seems.
Just wanted to provide a different option for this. In my case, I usually work on my individual branches then merge to master, and the individual commits I do to my local are not that important.
Due to a git hook that checks for the appropriate ticket number on Jira but was case sensitive, I was prevented from pushing my code. Also, the commit was done long ago and I didn't want to count how many commits to go back on the rebase.
So what I did was to create a new branch from latest master and squash all commits from problem branch into a single commit on new branch. It was easier for me and I think it's good idea to have it here as future reference.
From latest master:
git checkout -b new-branch
Then
git merge --squash problem-branch
git commit -m "new message"
How do you 'mark' 'tag' or 'release' a particular set of revisions for a particular set of files so you can always pull that one later?
Using the git tag
command.
To simply "tag" the current revision, you would just run..
git tag -a thetagname
git tag -a 0.1
git tag -a 2.6.1-rc1 -m 'Released on 01/02/03'
To list the current tags, simply run git tag
with no arguments, or -l
(lower case L):
$ git tag -a thetagname # and enter a message, or use -m 'My tag annotation'
$ git tag -l
thetagname
To delete a tag, you use the -d
flag:
$ git tag -d thetagname
Deleted tag 'thetagname'
$ git tag
[no output]
To tag a specific (previous) commit, you simply do..
git tag [tag name] [revision SHA1 hash]
For example:
git tag 1.1.1 81b15a68c6c3e71f72e766931df4e6499990385b
Note: by default, git creates a "lightweight" tag (basically a reference to a specific revision). The "right" way is to use the -a
flag. This will launch your editor asking for a tag message (identical to asking for a commit message, you can also use the -m
flag to supply the tag message on the command line). Using an annotated tag creates an object with its own ID, date, tagger (author), and optionally a GPG signature (using the -s
tag).
For further information on this, see this post
git tag mytagwithmsg -a -m 'This is a tag, with message'
And to list the tags with annotations, use the -n1
flag to show 1 line of each tag message (-n245
to show the first 245 lines of each annotation, and so on):
$ git tag -l -n1
mytagwithmsg This is a tag, with message
For more information, see the git-tag(1) Manual Page
Just rain into the same problem -- and here's how I addressed it.
Assuming mysqld is running, then the problem might just be the mysql client not knowing where to look for the socket file.
The most straightforward way to address this consists in adding the following line to your user's profile .my.cnf file (on linux that's usually under /home/myusername):
socket=<path to the mysql socket file>
If you don't have a .my.cnf file there, then create one containing the following:
[mysql]
socket=<path to the mysql socket file>
In my case, since I moved the mysql default data folder (/var/lib/mysql) in a different location (/data/mysql), I added to .my.cnf the following:
[mysql]
socket=/data/mysql/mysql.sock
Hope this helps.
If you just want to add the same header to all the requests to the service, you can do it with out any coding!
Just add the headers node with required headers under the endpoint node in your client config file
<client>
<endpoint address="http://localhost/..." >
<headers>
<HeaderName>Value</HeaderName>
</headers>
</endpoint>
You can get the total number of rows containing a specific name using:
SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'
Given the count, you can now get the nth row using:
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1
Where 1 <= n <= COUNT(*) from the first query.
Example:
getting the 3rd row
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1
If you're instantiating an android.support.v4.app.Fragment
class, the you have to call getActivity().getSupportFragmentManager()
to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity()
prefix.
Steps to install Spark in local mode:
Install Java 7 or later.
To test java installation is complete, open command prompt type java
and hit enter.
If you receive a message 'Java' is not recognized as an internal or external command.
You need to configure your environment variables, JAVA_HOME
and PATH
to point to the path of jdk.
Set SCALA_HOME
in Control Panel\System and Security\System
goto "Adv System settings" and add %SCALA_HOME%\bin
in PATH variable in environment variables.
Install Python 2.6 or later from Python Download link.
Download SBT. Install it and set SBT_HOME
as an environment variable with value as <<SBT PATH>>
.
Download winutils.exe
from HortonWorks repo or git repo. Since we don't have a local Hadoop installation on Windows we have to download winutils.exe
and place it in a bin
directory under a created Hadoop
home directory.
Set HADOOP_HOME = <<Hadoop home directory>>
in environment variable.
We will be using a pre-built Spark package, so choose a Spark pre-built package for Hadoop Spark download. Download and extract it.
Set SPARK_HOME
and add %SPARK_HOME%\bin
in PATH variable in environment variables.
Run command: spark-shell
Open http://localhost:4040/
in a browser to see the SparkContext web UI.
You can get at the data values like this:
string json = @"
[
{ ""General"" : ""At this time we do not have any frequent support requests."" },
{ ""Support"" : ""For support inquires, please see our support page."" }
]";
JArray a = JArray.Parse(json);
foreach (JObject o in a.Children<JObject>())
{
foreach (JProperty p in o.Properties())
{
string name = p.Name;
string value = (string)p.Value;
Console.WriteLine(name + " -- " + value);
}
}

If you're on .NET 3.5 or up, you can use the new System.DirectoryServices.AccountManagement

Update: older MSDN magazine articles aren't online anymore, unfortunately - you'll need to download the CHM for the January 2008 MSDN magazine from Microsoft and read the article in there.
Basically, you need to have a "principal context" (typically your domain), a user principal, and then you get its groups very easily:
public List<GroupPrincipal> GetGroups(string userName)
{
List<GroupPrincipal> result = new List<GroupPrincipal>();
// establish domain context
PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain);
// find your user
UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, userName);
// if found - grab its groups
if(user != null)
{
PrincipalSearchResult<Principal> groups = user.GetAuthorizationGroups();
// iterate over all groups
foreach(Principal p in groups)
{
// make sure to add only group principals
if(p is GroupPrincipal)
{
result.Add((GroupPrincipal)p);
}
}
}
return result;
}
and that's all there is! You now have a result (a list) of authorization groups that user belongs to - iterate over them, print out their names or whatever you need to do.
Update: In order to access certain properties, which are not surfaced on the UserPrincipal
object, you need to dig into the underlying DirectoryEntry
:
public string GetDepartment(Principal principal)
{
string result = string.Empty;
DirectoryEntry de = (principal.GetUnderlyingObject() as DirectoryEntry);
if (de != null)
{
if (de.Properties.Contains("department"))
{
result = de.Properties["department"][0].ToString();
}
}
return result;
}
Update #2: seems shouldn't be too hard to put these two snippets of code together.... but ok - here it goes:
public string GetDepartment(string username)
{
string result = string.Empty;
// if you do repeated domain access, you might want to do this *once* outside this method,
// and pass it in as a second parameter!
PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain);
// find the user
UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, username);
// if user is found
if(user != null)
{
// get DirectoryEntry underlying it
DirectoryEntry de = (user.GetUnderlyingObject() as DirectoryEntry);
if (de != null)
{
if (de.Properties.Contains("department"))
{
result = de.Properties["department"][0].ToString();
}
}
}
return result;
}
I had this issue and tried both, but had to settle for removing crap like "pageEditState", but not removing user info lest I have to look it up again.
public static void RemoveEverythingButUserInfo()
{
foreach (String o in HttpContext.Current.Session.Keys)
{
if (o != "UserInfoIDontWantToAskForAgain")
keys.Add(o);
}
}
This doesn't work for me, I want to to like jquery slideUp / slideDown function, I tried this code, but it only move the content wich stay at the same place after animation end, the view should have a 0dp height at start of slideDown and the view height (with wrap_content) after the end of the animation.
Here's a variation on some of the above answers that supports multiple transforms (keyval, key, value):
import { Pipe, PipeTransform } from '@angular/core';
type Args = 'keyval'|'key'|'value';
@Pipe({
name: 'mapToIterable',
pure: false
})
export class MapToIterablePipe implements PipeTransform {
transform(obj: {}, arg: Args = 'keyval') {
return arg === 'keyval' ?
Object.keys(obj).map(key => ({key: key, value: obj[key]})) :
arg === 'key' ?
Object.keys(obj) :
arg === 'value' ?
Object.keys(obj).map(key => obj[key]) :
null;
}
}
Usage
map = {
'a': 'aee',
'b': 'bee',
'c': 'see'
}
<div *ngFor="let o of map | mapToIterable">{{o.key}}: {{o.value}}</div>
<div>a: aee</div>
<div>b: bee</div>
<div>c: see</div>
<div *ngFor="let o of map | mapToIterable:'keyval'">{{o.key}}: {{o.value}}</div>
<div>a: aee</div>
<div>b: bee</div>
<div>c: see</div>
<div *ngFor="let k of map | mapToIterable:'key'">{{k}}</div>
<div>a</div>
<div>b</div>
<div>c</div>
<div *ngFor="let v of map | mapToIterable:'value'">{{v}}</div>
<div>aee</div>
<div>bee</div>
<div>see</div>

The default API level in the Cordova Android platform has been upgraded. On an Android 9 device, clear text communication is now disabled by default.

As noted in the comments, if you have not defined the android
XML namespace previously, you will receive an error: unbound prefix

You may also want to check your $PYTHONPATH
. I had changed mine in ~/.bashrc
in order to get another package to work.
To check your path:
echo $PYTHONPATH
To change your path (I use nano but you could edit another way)
nano ~/.bashrc
Look for the line with export PYTHONPATH
...
After making changes, don't forget to
source ~/.bashrc
As Jake has mentioned, the problem might be because of copy/paste code. Check the main.xml under res/layout. If there is no id field in that then you have a problem. A typical example would be as below
<com.androidplot.xy.XYPlot
android:id="@+id/mySimpleXYPlot"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="10px"
android:layout_marginLeft="20px"
android:layout_marginRight="20px"
title="A Simple Example"

From my point of view this error "Error: Aesthetics must either be length one, or the same length as the data" refers to the argument aes(x,y) I tried the na.omit() and worked just fine to me.
If you don't want to use the libraries and want simple answer then the code is given below:
def swap_alpha(test_string):
new_string = ""
for i in test_string:
if i.upper() in test_string:
new_string += i.lower()
elif i.lower():
new_string += i.upper()
else:
return "invalid "
return new_string
user_string = input("enter the string:")
updated = swap_alpha(user_string)
print(updated)
Stream<Integer> stream = Stream.of(1, 2, 3, 4, 5, 6);

I normally use on
instead of click
. It allow me to add more events listeners to a specific function.

In my opinion calling cls
with os
is a bad idea generally. Imagine if I manage to change the cls or clear command on your system, and you run your script as admin or root.
I got this working by installing the various plugins below.
Most of the time things just import by themselves as soon as I type the class name. Alternatively, a lightbulb appears that you can click on. Or you can push F1, and type "import..." and there are various options there too. I kinda use all of them. Also F1 Implement for implementing an interface is helpful, but doesn't always work.

"yearmon"
can be used alone as well:

[1] "Mar 2000"
Note:
"yearmon"
class objects sort in calendar order.
This will plot the monthly points at equally spaced intervals which is likely what is wanted; however, if it were desired to plot the points at unequally spaced intervals spaced in proportion to the number of days in each month then convert the index of z
to "Date"

Other answers to this question do not return what the OP needs, they will return a string like:
test1 test2 test3 test1 test3 test4
(notice that test1
and test3
are duplicated) while the OP wants to return this string:
test1 test2 test3 test4
the problem here is that the string "test1 test3"
is duplicated and is inserted only once, but all of the others are distinct to each other ("test1 test2 test3"
is distinct than "test1 test3"
, even if some tests contained in the whole string are duplicated).
What we need to do here is to split each string into different rows, and we first need to create a numbers table:
CREATE TABLE numbers (n INT);
INSERT INTO numbers VALUES
(1),(2),(3),(4),(5),(6),(7),(8),(9),(10);
then we can run this query:
SELECT
SUBSTRING_INDEX(
SUBSTRING_INDEX(tableName.categories, ' ', numbers.n),
' ',
-1) category
FROM
numbers INNER JOIN tableName
ON
LENGTH(tableName.categories)>=
LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1;
and we get a result like this:
test1
test4
test1
test1
test2
test3
test3
test3
and then we can apply GROUP_CONCAT aggregate function, using DISTINCT clause:
SELECT
GROUP_CONCAT(DISTINCT category ORDER BY category SEPARATOR ' ')
FROM (
SELECT
SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
FROM
numbers INNER JOIN tableName
ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
) s;
Please see fiddle here.
Add an ORDER BY ONE.ID ASC
at the end of your first query.
By default there is no ordering.
I tried above example but it was not showing more than 4000 characters then I modified it little bit and was able to get whole stored procedure definition. Please see the updated script below -

FROM SYSCOMMENTS AS C
INNER JOIN SYS.OBJECTS AS O ON C.ID = O.[OBJECT_ID]
INNER JOIN SYS.SCHEMAS AS S ON O.SCHEMA_ID = S.SCHEMA_ID
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%FOO%'
ORDER BY SCHEMA_NAME(O.SCHEMA_ID), O.NAME

Default rounding in python and numpy:
In: [round(i) for i in np.arange(10) + .5]
Out: [0, 2, 2, 4, 4, 6, 6, 8, 8, 10]
I used this to get integer rounding to be applied to a pandas series:
import decimal
and use this line to set the rounding to "half up" a.k.a rounding as taught in school:
decimal.getcontext().rounding = decimal.ROUND_HALF_UP
Finally I made this function to apply it to a pandas series object
def roundint(value):
return value.apply(lambda x: int(decimal.Decimal(x).to_integral_value()))
So now you can do roundint(df.columnname)
And for numbers:
In: [int(decimal.Decimal(i).to_integral_value()) for i in np.arange(10) + .5]
Out: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

It's also possible to do the same thing to support some older versions of IE (I think 6-8) using the ActiveX Object, I had some old code which does that too but its been a while so I'll have to dig it up I've found a solution similar to the one I used courtesy of Jacky Cui's blog and edited this answer (also cleaned up code a bit). Hope it helps.
Lastly, I just read some other answers that beat me to the draw, but as they suggest, you might be looking for code that lets you load a text file from the server (or device) where the JavaScript file is sitting. If that's the case then you want AJAX code to load the document dynamically which would be something as follows:
<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');
function loadFile() {
reader.open('get', 'test.txt', true);
reader.onreadystatechange = displayContents;
reader.send(null);
}
function displayContents() {
if(reader.readyState==4) {
var el = document.getElementById('main');
el.innerHTML = reader.responseText;
}
}
</script>
</head>
<body>
<div id="container">
<input type="button" value="test.txt" onclick="loadFile()" />
<div id="main">
</div>
</div>
</body>
</html>
Even though this is an older post, there is also another method to rendering for older versions of Internet Explorer. -webkit while being a CSS Vendor Prefix, you can also download a few JS applications and place them in the bottom of the HTML's HEAD.
Try using Modernizr, HTML5 Shiv and Respond.js. These are amazing IE compatible polyfill scripts that use polyfills, and other resources which will help better render HTML5 elements in IE9 and Below.
To use these polyfills, simply add HTML boolean logic to place them, IF the browser is less than the desire IE version. Example code is:
<head>_x000D_
<!-- HEAD Elements --> _x000D_
<script src="path/to/modernizr.js" type="text/javascript"></script>_x000D_
<!--[if lt IE 6]>_x000D_
<script src="path/to/HTMLSiv.js" type="text/javascript">_x000D_
</script>_x000D_
<script src="path/to/respond.js" type="text/javascript">_x000D_
</script>_x000D_
<![endif]-->_x000D_
</head>

@dhobbs's answer is great!
but simply change to easy get the level info
def print_list_dir(dir):
print("=" * 64)
print("[PRINT LIST DIR] %s" % dir)
print("=" * 64)
for root, dirs, files in os.walk(dir):
level = root.replace(dir, '').count(os.sep)
indent = '| ' * level
print('{}{} \\'.format(indent, os.path.basename(root)))
subindent = '| ' * (level + 1)
for f in files:
print('{}{}'.format(subindent, f))
print("=" * 64)
and the output like

In Windows 10 while installing Android SDK, by default latest SDK gets installed.
Platform List is part of Android SDK and the best way to find the location is to open SDK manager and get the path.
It will be available at:
Android SDK Location: C:\Users\<User Name>\AppData\Local\Android\sdk\platform-tools\
In SDK Manager, SDK path can be found by following the below
Appearance & Behaviour --> System Settings --> Android SDK
You can get the path where SDK is installed and can edit the location as well.
Yes, there is a way to emulate max-width
using a table, thus giving you both responsive and Outlook-friendly layout. What's more, this solution doesn't require conditional comments.
Suppose you want the equivalent of a centered div
with max-width
of 350px
. You create a table, set the width to 100%
. The table has three cells in a row. Set the width of the center TD
to 350
(using the HTML width
attribute, not CSS), and there you go.
If you want your content aligned left instead of centered, just leave out the first empty cell.
Example:
<table border="0" cellspacing="0" width="100%">
<tr>
<td></td>
<td width="350">The width of this cell should be a maximum of
350 pixels, but shrink to widths less than 350 pixels.
</td>
<td></td>
</tr>
</table>
In the jsfiddle I give the table a border so you can see what's going on, but obviously you wouldn't want one in real life:
If you are injecting something that needs the script tag, you may get an uncaught syntax error and say illegal token. To avoid this, be sure to escape the forward slashes in your closing script tag(s). ie;
var output += '<\/script>';
Same goes for any closing tags, such as a form tag.
A small change to what Sarfraz posted is:
$array = array(1, 2, 3, 4, 5);
$output = array_slice($array, 0, 1);
print_r ($output);
Function FileExists(fullFileName As String) As Boolean
FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End Function
Works very well, almost, at my site. If I call it with "" the empty string, Dir returns "connection.odc"!! Would be great if you guys could share your result.
Anyway, I do like this:
Function FileExists(fullFileName As String) As Boolean
If fullFileName = "" Then
FileExists = False
Else
FileExists = VBA.Len(VBA.Dir(fullFileName)) > 0
End If
End Function
Due to security issues (same origin policy), javascript access to local files is restricted if without user interaction.
According to https://developer.mozilla.org/en-US/docs/Same-origin_policy_for_file:_URIs:
A file can read another file only if the parent directory of the originating file is an ancestor directory of the target file.
Imagine a situation when javascript from a website tries to steal your files anywhere in your system without you being aware of. You have to deploy it to a web server. Or try to load it with a script tag. Like this:
<script type="text/javascript" language="javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript" language="javascript" src="priorities.json"></script>
<script type="text/javascript">
$(document).ready(function(e) {
alert(jsonObject.start.count);
});
</script>
Your priorities.json file:
var jsonObject = {
"start": {
"count": "5",
"title": "start",
"priorities": [
{
"txt": "Work"
},
{
"txt": "Time Sense"
},
{
"txt": "Dicipline"
},
{
"txt": "Confidence"
},
{
"txt": "CrossFunctional"
}
]
}
}
Or declare a callback function on your page and wrap it like jsonp technique:
<script type="text/javascript" language="javascript" src="jquery-1.8.2.min.js"> </script>
<script type="text/javascript">
$(document).ready(function(e) {
});
function jsonCallback(jsonObject){
alert(jsonObject.start.count);
}
</script>
<script type="text/javascript" language="javascript" src="priorities.json"></script>
Your priorities.json file:
jsonCallback({
"start": {
"count": "5",
"title": "start",
"priorities": [
{
"txt": "Work"
},
{
"txt": "Time Sense"
},
{
"txt": "Dicipline"
},
{
"txt": "Confidence"
},
{
"txt": "CrossFunctional"
}
]
}
})
Using script tag is a similar technique to JSONP, but with this approach it's not so flexible. I recommend deploying it on a web server.
With user interaction, javascript is allowed access to files. That's the case of File API. Using file api, javascript can access files selected by the user from <input type="file"/>
or dropped from the desktop to the browser.
Technically you can if you use something like OpenCL, but Nvidia's CUDA is much better and OpenCL requires other steps that may or may not work. I would recommend if you have an AMD gpu, use something like Google Colab where they provide a free Nvidia GPU you can use when coding.
I wondered the same myself. I found that under File(menu) there is an item "Project Settings". It opens a dialog box with 3 choices: "Default Location", "Project-relative Location", and "Custom location" "Project-relative" puts the build products in the project folder, like before. This is not in the Preferences menu and must be set every time a project is created. Hope this helps.
There could be following things in your settings.py:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': ["templates"],
'APP_DIRS': True,
'OPTIONS': {
# ... some options here ...
},
},
]
OR
STATIC_URL = '/static/'
OR
STATICFILES_DIRS = ( os.path.join(BASE_DIR, "static"), )
There are a plethora of ways in which this can be done. The problem is how to make R aware of the locations of the variables you wish to divide.
Assuming
d <- read.table(text = "263807.0 1582
196190.5 1016
586689.0 3479
")
names(d) <- c("min", "count2.freq")
> d
min count2.freq
1 263807.0 1582
2 196190.5 1016
3 586689.0 3479
To add the desired division as a third variable I would use transform()
> d <- transform(d, new = min / count2.freq)
> d
min count2.freq new
1 263807.0 1582 166.7554
2 196190.5 1016 193.1009
3 586689.0 3479 168.6373
If doing this in a function (i.e. you are programming) then best to avoid the sugar shown above and index. In that case any of these would do what you want
## 1. via `[` and character indexes
d[, "new"] <- d[, "min"] / d[, "count2.freq"]
## 2. via `[` with numeric indices
d[, 3] <- d[, 1] / d[, 2]
## 3. via `$`
d$new <- d$min / d$count2.freq
All of these can be used at the prompt too, but which is easier to read:
d <- transform(d, new = min / count2.freq)
or
d$new <- d$min / d$count2.freq ## or any of the above examples
Hopefully you think like I do and the first version is better ;-)
The reason we don't use the syntactic sugar of tranform()
et al when programming is because of how they do their evaluation (look for the named variables). At the top level (at the prompt, working interactively) transform()
et al work just fine. But buried in function calls or within a call to one of the apply()
family of functions they can and often do break.
Likewise, be careful using numeric indices (## 2.
above); if you change the ordering of your data, you will select the wrong variables.
If you are just wanting to do the division (rather than insert the result back into the data frame, then use with()
, which allows us to isolate the simple expression you wish to evaluate
> with(d, min / count2.freq)
[1] 166.7554 193.1009 168.6373
This is again much cleaner code than the equivalent
> d$min / d$count2.freq
[1] 166.7554 193.1009 168.6373
as it explicitly states that "using d
, execute the code min / count2.freq
. Your preference may be different to mine, so I have shown all options.
For the special case where you search for the n'th occurence of a character (i.e. substring of length 1), the following function works by building a list of all positions of occurences of the given character:
def find_char_nth(string, char, n):
"""Find the n'th occurence of a character within a string."""
return [i for i, c in enumerate(string) if c == char][n-1]
If there are fewer than n
occurences of the given character, it will give IndexError: list index out of range
.
This is derived from @Zv_oDD's answer and simplified for the case of a single character.
I use this which is standard for every time
import datetime
now = datetime.datetime.now()
print ("Current date and time : ")
print (now.strftime("%Y-%m-%d %H:%M:%S"))
If you mean "how can I get a reference to all markers on a given map" - then I think the answer is "Sorry, you have to do it yourself". I don't think there is any handy "maps.getMarkers()" type function: you have to keep your own references as the points are created:
var allMarkers = [];
....
// Create some markers
for(var i = 0; i < 10; i++) {
var marker = new google.maps.Marker({...});
allMarkers.push(marker);
}
...
Then you can loop over the allMarkers
array to and do whatever you need to do.
No you can't set them as single one for example if you have div{ border-top: 2px solid red; border-right: 2px solid red; border-bottom: 2px solid red; border-left: 2px solid red; } same properties for all fours then you can set them in single line
div{border:2px solid red;}
SELECT A.COLUMN_NAME, A.* FROM all_tab_columns a
WHERE table_name = 'Your Table Name'
AND A.COLUMN_NAME = 'COLUMN NAME' AND a.owner = 'Schema'
from IPython.utils.io import Tee
from contextlib import closing
print('This is not in the output file.')
with closing(Tee("outputfile.log", "w", channel="stdout")) as outputstream:
print('This is written to the output file and the console.')
# raise Exception('The file "outputfile.log" is closed anyway.')
print('This is not written to the output file.')
# Output on console:
# This is not in the output file.
# This is written to the output file and the console.
# This is not written to the output file.
# Content of file outputfile.txt:
# This is written to the output file and the console.
The Tee
class in IPython.utils.io
does what you want, but it lacks the __enter__
and __exit__
methods needed to call it in the with
-statement. Those are added by contextlib.closing
.
I alway do it like this:
$(document).ready(function(){
var maxChars = $("#sessionNum");
var max_length = maxChars.attr('maxlength');
if (max_length > 0) {
maxChars.on('keyup', function(e){
length = new Number(maxChars.val().length);
counter = max_length-length;
$("#sessionNum_counter").text(counter);
});
}
});
Input:
<input name="sessionNum" id="sessionNum" maxlength="5" type="text">
Number of chars: <span id="sessionNum_counter">5</span>
If you want to remove all control characters, including CR and LF, you can use this:
myString.replace(/[^\x20-\x7E]/gmi, "")
It will remove all non-printable characters. This are all characters NOT within the ASCII HEX space 0x20-0x7E
. Feel free to modify the HEX range as needed.
How about subtracting one and changing Sunday
IF(DAYOFWEEK() = 1, 7, DAYOFWEEK() - 1)
Of course you would have to do this for every query.
Find duplicate Records:
Suppose we have table : Student
student_id int
student_name varchar
Records:
+------------+---------------------+
| student_id | student_name |
+------------+---------------------+
| 101 | usman |
| 101 | usman |
| 101 | usman |
| 102 | usmanyaqoob |
| 103 | muhammadusmanyaqoob |
| 103 | muhammadusmanyaqoob |
+------------+---------------------+
Now we want to see duplicate records
Use this query:
select student_name,student_id ,count(*) c from student group by student_id,student_name having c>1;
+--------------------+------------+---+
| student_name | student_id | c |
+---------------------+------------+---+
| usman | 101 | 3 |
| muhammadusmanyaqoob | 103 | 2 |
+---------------------+------------+---+
A bit similar to @bpile answer, my case was a my.cnf entry setting collation-server = utf8_general_ci
. After I realized that (and after trying everything above), I forcefully switched my database to utf8_general_ci instead of utf8_unicode_ci and that was it:
ALTER DATABASE `db` CHARACTER SET utf8 COLLATE utf8_general_ci;
It failed because you used ajax="false"
. This fires a full synchronous request which in turn causes a full page reload, causing the oncomplete
to be never fired (note that all other ajax-related attributes like process
, onstart
, onsuccess
, onerror
and update
are also never fired).
That it worked when you removed actionListener
is also impossible. It should have failed the same way. Perhaps you also removed ajax="false"
along it without actually understanding what you were doing. Removing ajax="false"
should indeed achieve the desired requirement.
Also is it possible to execute actionlistener and oncomplete simultaneously?
No. The script can only be fired before or after the action listener. You can use onclick
to fire the script at the moment of the click. You can use onstart
to fire the script at the moment the ajax request is about to be sent. But they will never exactly simultaneously be fired. The sequence is as follows:
onclick
JavaScript code is executedprocess
and current HTML DOM treeonstart
JavaScript code is executedprocess
actionListener
JSF backing bean method is executedaction
JSF backing bean method is executedupdate
and current JSF component treeonsuccess
JavaScript code is executedonerror
JavaScript code is executedupdate
based on ajax response and current HTML DOM treeoncomplete
JavaScript code is executedNote that the update
is performed after actionListener
, so if you were using onclick
or onstart
to show the dialog, then it may still show old content instead of updated content, which is poor for user experience. You'd then better use oncomplete
instead to show the dialog. Also note that you'd better use action
instead of actionListener
when you intend to execute a business action.
The Tkinter library in the Python standard library is an interactive tool which you can import. Basically, you can create buttons and boxes and popups and stuff that appear as windows which you manipulate with code.
If you use Tkinter, do not use time.sleep()
, because it will muck up your program. This happened to me. Instead, use root.after()
and replace the values for however many seconds, with a milliseconds. For example, time.sleep(1)
is equivalent to root.after(1000)
in Tkinter.
Otherwise, time.sleep()
, which many answers have pointed out, which is the way to go.
I believe you want to use CHARINDEX
. You can read about it here.
I came across a case where I thought I wanted to pass the "address" of an object property as data to another function and populate the object (with AJAX), do lookup from address array, and display in that other function. I couldn't use dot notation without doing string acrobatics so I thought an array might be nice to pass instead. I ended-up doing something different anyway, but seemed related to this post.
Here's a sample of a language file object like the one I wanted data from:
const locs = {
"audioPlayer": {
"controls": {
"start": "start",
"stop": "stop"
},
"heading": "Use controls to start and stop audio."
}
}
I wanted to be able to pass an array such as: ["audioPlayer", "controls", "stop"] to access the language text, "stop" in this case.
I created this little function that looks-up the "least specific" (first) address parameter, and reassigns the returned object to itself. Then it is ready to look-up the next-most-specific address parameter if one exists.
function getText(selectionArray, obj) {
selectionArray.forEach(key => {
obj = obj[key];
});
return obj;
}
usage:
/* returns 'stop' */
console.log(getText(["audioPlayer", "controls", "stop"], locs));
/* returns 'use controls to start and stop audio.' */
console.log(getText(["audioPlayer", "heading"], locs));

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.
Here is an attempt at this with your data:
import matplotlib.pyplot as plt
# ... define 2D array hist as you did
plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case
You need to overload operator <<
for mystruct
class
Something like :-
friend ostream& operator << (ostream& os, const mystruct& m)
{
os << m.m_a <<" " << m.m_b << endl;
return os ;
}

I think the closest collection you'll get from the framework is the SortedMap
$query = DB::table('dms_stakeholder_permissions');
$query->select(DB::raw('group_concat(dms_stakeholder_permissions.fid) as fid'),'dms_stakeholder_permissions.rights');
$query->where('dms_stakeholder_permissions.stakeholder_id','4');
$query->orWhere(function($subquery) use ($stakeholderId){
$subquery->where('dms_stakeholder_permissions.stakeholder_id',$stakeholderId);
$subquery->whereIn('dms_stakeholder_permissions.rights',array('1','2','3'));
});
$result = $query->get();
return $result;
// OUTPUT @input $stakeholderId = 1
//select group_concat(dms_stakeholder_permissions.fid) as fid, dms_stakeholder_permissionss
.rights

Maybe this will help you:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
Try this:
$("#message span").text("hello world!");
See it in your code!
function Errormessage(txt) {
var m = $("#message");
// set text before displaying message
m.children("span").text(txt);
// bind close listener
m.children("a.close-notify").click(function(){
m.fadeOut("slow");
});
// display message
m.fadeIn("slow");
}
I will give a practical example in scraping web data using python, a lot of the times you will get keys with no values, in those cases you will get errors if you use dictionary['key'], whereas dictionary.get('key', 'return_otherwise') has no problems.
Similarly, I would use ''.join(list) as opposed to list[0] if you try to capture a single value from a list.
hope it helps.
[Edit] Here is a practical example:
Say, you are calling an API, which returns a JOSN file you need to parse. The first JSON looks like following:
{"bids":{"id":16210506,"submitdate":"2011-10-16 15:53:25","submitdate_f":"10\/16\/2011 at 21:53 CEST","submitdate_f2":"p\u0159ed 2 lety","submitdate_ts":1318794805,"users_id":"2674360","project_id":"1250499"}}
The second JOSN is like this:
{"bids":{"id":16210506,"submitdate":"2011-10-16 15:53:25","submitdate_f":"10\/16\/2011 at 21:53 CEST","submitdate_f2":"p\u0159ed 2 lety","users_id":"2674360","project_id":"1250499"}}
Note that the second JSON is missing the "submitdate_ts" key, which is pretty normal in any data structure.
So when you try to access the value of that key in a loop, can you call it with the following:
for item in API_call:
submitdate_ts = item["bids"]["submitdate_ts"]
You could, but it will give you a traceback error for the second JSON line, because the key simply doesn't exist.
The appropriate way of coding this, could be the following:
for item in API_call:
submitdate_ts = item.get("bids", {'x': None}).get("submitdate_ts")
{'x': None} is there to avoid the second level getting an error. Of course you can build in more fault tolerance into the code if you are doing scraping. Like first specifying a if condition
Make sure you don't have any firewalls blocking SMTP. The first time I tried to send an email, it was blocked both by Windows Firewall and McAfee - took forever to find them both.
the val
function called from the select
will return an array if its a multiple. $('select#my_multiselect').val()
will return an array of the values for the selected options - you dont need to loop through and get them yourself.
You can simply do this. In php, you can determine button click by use of
if(isset($_Post['button_tag_name']){
echo "Button Clicked";
}
Therefore you should modify you code as follows:
<?php
if(isset($_Post['select']){
echo "select button clicked and select method should be executed";
}
if(isset($_Post['insert']){
echo "insert button clicked and insert method should be executed";
}
?>

I too got the same error and struggled a lot in fixing this issue. Spent quiet a bit time in searching Google and found the following solution and my issue got resolved.
the issue was due to, missing Struts2 Libraries in the deployment path. Most of the folks may put the libraries for compilation and tend to forget to attach required libraries for run-time. So I added the same libraries in the web deployment assembly, and the issue was OFF.
Works for me: IntelliJ IDEA 13.1.1, JUnit4, Java 6
I changed the file in project path: [PROJECT_NAME].iml
Replaced:
<library>
<CLASSES>
<root url="jar://$APPLICATION_HOME_DIR$/lib/junit-4.11.jar!/" />
</CLASSES>
<JAVADOC />
<SOURCES />
</library>
By:
<library name="JUnit4">
<CLASSES>
<root url="jar://$APPLICATION_HOME_DIR$/lib/junit-4.11.jar!/" />
<root url="jar://$APPLICATION_HOME_DIR$/lib/hamcrest-core-1.3.jar!/" />
<root url="jar://$APPLICATION_HOME_DIR$/lib/hamcrest-library-1.3.jar!/" />
</CLASSES>
<JAVADOC />
<SOURCES />
</library>
So the final .iml file is:
<?xml version="1.0" encoding="UTF-8"?>
<module type="JAVA_MODULE" version="4">
<component name="NewModuleRootManager" inherit-compiler-output="true">
<exclude-output />
<content url="file://$MODULE_DIR$">

<sourceFolder url="file://$MODULE_DIR$/tests" isTestSource="true" />
</content>
<orderEntry type="inheritedJdk" />
<orderEntry type="sourceFolder" forTests="false" />
<orderEntry type="module-library">

</CLASSES>
<JAVADOC />
<SOURCES />
</library>
</orderEntry>
</component>
</module>
P.S.: save the file and don't let to IntelliJ Idea reload it. Just once.
I solved the problem adding this code:
String confString = HttpContext.Current.Request.ApplicationPath.ToString();
Configuration conf = WebConfigurationManager.OpenWebConfiguration(confString);
ScriptingJsonSerializationSection section = (ScriptingJsonSerializationSection)conf.GetSection("system.web.extensions/scripting/webServices/jsonSerialization");
section.MaxJsonLength = 6553600;
conf.Save();
Since your JPA repository name is UserBoardRepository, your custom Interface name should be UserBoardRepositoryCustom (it should end with 'Custom') and your implementation class name should be UserBoardRepositoryImpl (should end with Impl; you can set it with a different postfix using the repository-impl-postfix property)
There are multiple ways to get the last inserted ID after insert command.
@@IDENTITY
: It returns the last Identity value generated on a Connection in current session, regardless of Table and the scope of statement that produced the valueSCOPE_IDENTITY()
: It returns the last identity value generated by the insert statement in the current scope in the current connection regardless of the table.IDENT_CURRENT(‘TABLENAME’)
: It returns the last identity value generated on the specified table regardless of Any connection, session or scope. IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. Now it seems more difficult to decide which one will be exact match for my requirement.
I mostly prefer SCOPE_IDENTITY().
If you use select SCOPE_IDENTITY() along with TableName in insert statement, you will get the exact result as per your expectation.

Try the following -
mylist = [1, 2, 3, 4]
def add(mylist):
total = 0
for i in mylist:
total += i
return total
result = add(mylist)
print("sum = ", result)
iif has always been available in VB, even in VB6.
Dim foo as String = iif(bar = buz, cat, dog)
It is not a true operator, as such, but a function in the Microsoft.VisualBasic namespace.
Clearly you need a factory pattern!
KeyFactory keyFactory = new KeyFactory();
KeyObj keyObj = keyFactory.getKeyObj(wParam);
keyObj.doStuff();
class VK_F11 extends KeyObj {
boolean val;
public void doStuff() {
val = !val;
}
}
class VK_F12 extends KeyObj {
boolean val;
public void doStuff() {
val = !val;
}
}
class KeyFactory {
public KeyObj getKeyObj(int param) {
switch(param) {
case VK_F11:
return new VK_F11();
case VK_F12:
return new VK_F12();
}
throw new KeyNotFoundException("Key " + param + " was not found!");
}
}
:D

Just an extension on the previous answers here. Two parts to ensure, Make sure that you add in extraData and that your keyExtractor is unique. If your keyExtractor is constant a rerender will not be triggered.
<FlatList
data={this.state.AllArray}
extraData={this.state.refresh}
renderItem={({ item,index })=>this.renderPhoto(item,index)}
keyExtractor={item => item.id}
>
</FlatList>
Try using the QueryDefs. Create the query with parameters. Then use something like this:
Dim dbs As DAO.Database
Dim qdf As DAO.QueryDef
Set dbs = CurrentDb
Set qdf = dbs.QueryDefs("Your Query Name")
qdf.Parameters("Parameter 1").Value = "Parameter Value"
qdf.Parameters("Parameter 2").Value = "Parameter Value"
qdf.Execute
qdf.Close
Set qdf = Nothing
Set dbs = Nothing
using jQuery UI you can use the dialog that offers. More information at http://docs.jquery.com/UI/Dialog
With Go 1.5 they seem to have improved the cross compilation process, meaning it is built in now. No ./make.bash
-ing or brew
-ing required. The process is described here but for the TLDR-ers (like me) out there: you just set the GOOS
and the GOARCH
environment variables and run the go build.
For the even lazier copy-pasters (like me) out there, do something like this if you're on a *nix system:
env GOOS=linux GOARCH=arm go build -v github.com/path/to/your/app
You even learned the env
trick, which let you set environment variables for that command only, completely free of charge.
I would achieve it in a one-liner as shown below:
using System;
using System.Collections;
namespace stackoverflowQuestions
{
class Program
{
static void Main(string[] args)
{
//get bit Array for number 20
var myBitArray = new BitArray(BitConverter.GetBytes(20));
}
}
}
Please note that every element of a BitArray
is stored as bool as shown in below snapshot:
So below code works:
if (myBitArray[0] == false)
{
//this code block will execute
}
but below code doesn't compile at all:
if (myBitArray[0] == 0)
{
//some code
}
Selecting a checkbox is similar to clicking a button.
driver.findElement(By.id("idOfTheElement")).click();
will do.
However, you can also see whether the checkbox is already checked. The following snippet checks whether the checkbox is selected or not. If it is not selected, then it selects.
if ( !driver.findElement(By.id("idOfTheElement")).isSelected() )
{
driver.findElement(By.id("idOfTheElement")).click();
}
Maybe less Professional but simpler solution could be make a DateTime parameter at consumer method.For example instead of make method like SampleMethod , make SampleMethod1 with parameter.Testing of SampleMethod1 is easier
public void SampleMethod()
{
DateTime anotherDateTime = DateTime.Today.AddDays(-10);
if ((DateTime.Now-anotherDateTime).TotalDays>10)
{
}
}
public void SampleMethod1(DateTime dateTimeNow)
{
DateTime anotherDateTime = DateTime.Today.AddDays(-10);
if ((dateTimeNow - anotherDateTime).TotalDays > 10)
{
}
}
Ok, I know this was answered a long time ago... but, here's some new info:
Say the Contact class in question already has a defined natural ordering via implementing Comparable, but you want to override that ordering, say by name. Here's the modern way to do it:
List<Contact> contacts = ...;
contacts.sort(Comparator.comparing(Contact::getName).reversed().thenComparing(Comparator.naturalOrder());
This way it will sort by name first (in reverse order), and then for name collisions it will fall back to the 'natural' ordering implemented by the Contact class itself.
Try using SMTP to send email:-
$mail->IsSMTP();
$mail->Host = "smtp.example.com";
// optional
// used only when SMTP requires authentication
$mail->SMTPAuth = true;
$mail->Username = 'smtp_username';
$mail->Password = 'smtp_password';
Keep in mind that most of the techniques here are valid presuming that round-off error due to prior calculations is not a factor. E.g. you could use roundf
, like this:
float z = 1.0f;
if (roundf(z) == z) {
printf("integer\n");
} else {
printf("fraction\n");
}
The problem with this and other similar techniques (such as ceilf
, casting to long
, etc.) is that, while they work great for whole number constants, they will fail if the number is a result of a calculation that was subject to floating-point round-off error. For example:
float z = powf(powf(3.0f, 0.05f), 20.0f);
if (roundf(z) == z) {
printf("integer\n");
} else {
printf("fraction\n");
}
Prints "fraction", even though (31/20)20 should equal 3, because the actual calculation result ended up being 2.9999992847442626953125.
Any similar method, be it fmodf
or whatever, is subject to this. In applications that perform complex or rounding-prone calculations, usually what you want to do is define some "tolerance" value for what constitutes a "whole number" (this goes for floating-point equality comparisons in general). We often call this tolerance epsilon. For example, lets say that we'll forgive the computer for up to +/- 0.00001 rounding error. Then, if we are testing z
, we can choose an epsilon of 0.00001 and do:
if (fabsf(roundf(z) - z) <= 0.00001f) {
printf("integer\n");
} else {
printf("fraction\n");
}
You don't really want to use ceilf
here because e.g. ceilf(1.0000001)
is 2 not 1, and ceilf(-1.99999999)
is -1 not -2.
You could use rintf
in place of roundf
if you prefer.
Choose a tolerance value that is appropriate for your application (and yes, sometimes zero tolerance is appropriate). For more information, check out this article on comparing floating-point numbers.
The common way of calculating the similarity between two strings in a 0%-100% fashion, as used in many libraries, is to measure how much (in %) you'd have to change the longer string to turn it into the shorter:
/**
* Calculates the similarity (a number within 0 and 1) between two strings.
*/
public static double similarity(String s1, String s2) {
String longer = s1, shorter = s2;
if (s1.length() < s2.length()) { // longer should always have greater length
longer = s2; shorter = s1;
}
int longerLength = longer.length();
if (longerLength == 0) { return 1.0; /* both strings are zero length */ }
return (longerLength - editDistance(longer, shorter)) / (double) longerLength;
}
// you can use StringUtils.getLevenshteinDistance() as the editDistance() function
// full copy-paste working code is below
editDistance()
:The editDistance()
function above is expected to calculate the edit distance between the two strings. There are several implementations to this step, each may suit a specific scenario better. The most common is the Levenshtein distance algorithm and we'll use it in our example below (for very large strings, other algorithms are likely to perform better).
Here's two options to calculate the edit distance:
apply(CharSequence left, CharSequence rightt)
public class StringSimilarity {
/**
* Calculates the similarity (a number within 0 and 1) between two strings.
*/
public static double similarity(String s1, String s2) {
String longer = s1, shorter = s2;
if (s1.length() < s2.length()) { // longer should always have greater length
longer = s2; shorter = s1;
}
int longerLength = longer.length();
if (longerLength == 0) { return 1.0; /* both strings are zero length */ }
/* // If you have Apache Commons Text, you can use it to calculate the edit distance:
LevenshteinDistance levenshteinDistance = new LevenshteinDistance();
return (longerLength - levenshteinDistance.apply(longer, shorter)) / (double) longerLength; */
return (longerLength - editDistance(longer, shorter)) / (double) longerLength;
}
// Example implementation of the Levenshtein Edit Distance
// See http://rosettacode.org/wiki/Levenshtein_distance#Java
public static int editDistance(String s1, String s2) {
s1 = s1.toLowerCase();
s2 = s2.toLowerCase();
int[] costs = new int[s2.length() + 1];
for (int i = 0; i <= s1.length(); i++) {
int lastValue = i;
for (int j = 0; j <= s2.length(); j++) {
if (i == 0)
costs[j] = j;
else {
if (j > 0) {
int newValue = costs[j - 1];
if (s1.charAt(i - 1) != s2.charAt(j - 1))
newValue = Math.min(Math.min(newValue, lastValue),
costs[j]) + 1;
costs[j - 1] = lastValue;
lastValue = newValue;
}
}
}
if (i > 0)
costs[s2.length()] = lastValue;
}
return costs[s2.length()];
}
public static void printSimilarity(String s, String t) {
System.out.println(String.format(
"%.3f is the similarity between \"%s\" and \"%s\"", similarity(s, t), s, t));
}
public static void main(String[] args) {
printSimilarity("", "");
printSimilarity("1234567890", "1");
printSimilarity("1234567890", "123");
printSimilarity("1234567890", "1234567");
printSimilarity("1234567890", "1234567890");
printSimilarity("1234567890", "1234567980");
printSimilarity("47/2010", "472010");
printSimilarity("47/2010", "472011");
printSimilarity("47/2010", "AB.CDEF");
printSimilarity("47/2010", "4B.CDEFG");
printSimilarity("47/2010", "AB.CDEFG");
printSimilarity("The quick fox jumped", "The fox jumped");
printSimilarity("The quick fox jumped", "The fox");
printSimilarity("kitten", "sitting");
}
}
Output:
1.000 is the similarity between "" and ""
0.100 is the similarity between "1234567890" and "1"
0.300 is the similarity between "1234567890" and "123"

0.857 is the similarity between "47/2010" and "472010"
0.714 is the similarity between "47/2010" and "472011"

0.571 is the similarity between "kitten" and "sitting"
You can use a lambda:
Collectors.toMap(p -> p.getLast(), Function.identity())
or, more concisely, you can use a method reference using ::
:
Collectors.toMap(Person::getLast, Function.identity())
and instead of Function.identity
, you can simply use the equivalent lambda:
Collectors.toMap(Person::getLast, p -> p)
If you use Netbeans you should get hints whenever an anonymous class can be replaced by a lambda.
Configuring Identity to your existing project is not hard thing. You must install some NuGet package and do some small configuration.
First install these NuGet packages with Package Manager Console:
PM> Install-Package Microsoft.AspNet.Identity.Owin
PM> Install-Package Microsoft.AspNet.Identity.EntityFramework
PM> Install-Package Microsoft.Owin.Host.SystemWeb
Add a user class and with IdentityUser
inheritance:
public class AppUser : IdentityUser
{
//add your custom properties which have not included in IdentityUser before
public string MyExtraProperty { get; set; }
}
Do same thing for role:
public class AppRole : IdentityRole
{
public AppRole() : base() { }
public AppRole(string name) : base(name) { }
// extra properties here
}
Change your DbContext
parent from DbContext
to IdentityDbContext<AppUser>
like this:
public class MyDbContext : IdentityDbContext<AppUser>
{
// Other part of codes still same
// You don't need to add AppUser and AppRole
// since automatically added by inheriting form IdentityDbContext<AppUser>
}
If you use the same connection string and enabled migration, EF will create necessary tables for you.
Optionally, you could extend UserManager
to add your desired configuration and customization:
public class AppUserManager : UserManager<AppUser>
{
public AppUserManager(IUserStore<AppUser> store)
: base(store)
{
}
// this method is called by Owin therefore this is the best place to configure your User Manager
public static AppUserManager Create(
IdentityFactoryOptions<AppUserManager> options, IOwinContext context)
{
var manager = new AppUserManager(
new UserStore<AppUser>(context.Get<MyDbContext>()));
// optionally configure your manager
// ...
return manager;
}
}
Since Identity is based on OWIN you need to configure OWIN too:
Add a class to App_Start
folder (or anywhere else if you want). This class is used by OWIN. This will be your startup class.
namespace MyAppNamespace
{
public class IdentityConfig
{
public void Configuration(IAppBuilder app)
{
app.CreatePerOwinContext(() => new MyDbContext());
app.CreatePerOwinContext<AppUserManager>(AppUserManager.Create);
app.CreatePerOwinContext<RoleManager<AppRole>>((options, context) =>
new RoleManager<AppRole>(
new RoleStore<AppRole>(context.Get<MyDbContext>())));
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Home/Login"),
});
}
}
}
Almost done just add this line of code to your web.config
file so OWIN could find your startup class.
<appSettings>
<!-- other setting here -->
<add key="owin:AppStartup" value="MyAppNamespace.IdentityConfig" />
</appSettings>
Now in entire project you could use Identity just like any new project had already installed by VS. Consider login action for example
[HttpPost]
public ActionResult Login(LoginViewModel login)
{
if (ModelState.IsValid)
{
var userManager = HttpContext.GetOwinContext().GetUserManager<AppUserManager>();
var authManager = HttpContext.GetOwinContext().Authentication;
AppUser user = userManager.Find(login.UserName, login.Password);
if (user != null)
{
var ident = userManager.CreateIdentity(user,
DefaultAuthenticationTypes.ApplicationCookie);
//use the instance that has been created.
authManager.SignIn(
new AuthenticationProperties { IsPersistent = false }, ident);
return Redirect(login.ReturnUrl ?? Url.Action("Index", "Home"));
}
}
ModelState.AddModelError("", "Invalid username or password");
return View(login);
}
You could make roles and add to your users:
public ActionResult CreateRole(string roleName)
{
var roleManager=HttpContext.GetOwinContext().GetUserManager<RoleManager<AppRole>>();
if (!roleManager.RoleExists(roleName))
roleManager.Create(new AppRole(roleName));
// rest of code
}
You could also add a role to a user, like this:
UserManager.AddToRole(UserManager.FindByName("username").Id, "roleName");
By using Authorize
you could guard your actions or controllers:
[Authorize]
public ActionResult MySecretAction() {}
or
[Authorize(Roles = "Admin")]]
public ActionResult MySecretAction() {}
You can also install additional packages and configure them to meet your requirement like Microsoft.Owin.Security.Facebook
or whichever you want.
Note: Don't forget to add relevant namespaces to your files:
using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;
You could also see my other answers like this and this for advanced use of Identity.
Sure, the syntax is exactly the same as C - NewObj* pNew = (NewObj*)oldObj;
In this situation you may wish to consider supplying this list as a parameter to the constructor, something like:
// SelectionListViewController
-(id) initWith:(SomeListClass*)anItemList
{
self = [super init];
if ( self ) {
[self setList: anItemList];
}
return self;
}
Then use it like this:
myEditController = [[SelectionListViewController alloc] initWith: listOfItems];
If each user has its own SQL Server login you could try this
select
so.name, su.name, so.crdate
from
sysobjects so
join
sysusers su on so.uid = su.uid
order by
so.crdate
public static void main(String[] args) {
@SuppressWarnings("serial")
List<Object> lst = new ArrayList<Object>() {
@Override
public boolean add(Object e) {
if(!contains(e))
return super.add(e);
else
return false;
}
};
lst.add("ABC");
lst.add("ABC");
lst.add("ABCD");
lst.add("ABCD");
lst.add("ABCE");
System.out.println(lst);
}
This is the better way
This is and old question, but answering may help others.
Default path where Android saves databases can not be accesed on non-rooted devices. So, the easiest way to access to database file (only for debugging environments) is to modify the constructor of the class:
public class MySQLiteOpenHelper extends SQLiteOpenHelper {
MySQLiteOpenHelper(Context context) {
super(context, "/mnt/sdcard/database_name.db", null, 0);
}
}
Remember to change for production environments with these lines:
public class MySQLiteOpenHelper extends SQLiteOpenHelper {
MySQLiteOpenHelper(Context context) {
super(context, "database_name.db", null, 0);
}
}
A logging script that I have written some time ago might be of help, although it is not exactly what you want. It acts in a way like a System.out.println but with much more information about StackTrace etc. It also provides Clickable text for Eclipse:
private static final SimpleDateFormat extended = new SimpleDateFormat( "dd MMM yyyy (HH:mm:ss) zz" );
public static java.util.logging.Logger initLogger(final String name) {
final java.util.logging.Logger logger = java.util.logging.Logger.getLogger( name );
try {
Handler ch = new ConsoleHandler();
logger.addHandler( ch );
logger.setLevel( Level.ALL ); // Level selbst setzen
logger.setUseParentHandlers( false );
final java.util.logging.SimpleFormatter formatter = new SimpleFormatter() {
@Override
public synchronized String format(final LogRecord record) {
StackTraceElement[] trace = new Throwable().getStackTrace();
String clickable = "(" + trace[ 7 ].getFileName() + ":" + trace[ 7 ].getLineNumber() + ") ";
/* Clickable text in Console. */
for( int i = 8; i < trace.length; i++ ) {
/* 0 - 6 is the logging trace, 7 - x is the trace until log method was called */
if( trace[ i ].getFileName() == null )
continue;
clickable = "(" + trace[ i ].getFileName() + ":" + trace[ i ].getLineNumber() + ") -> " + clickable;
}
final String time = "<" + extended.format( new Date( record.getMillis() ) ) + "> ";
StringBuilder level = new StringBuilder("[" + record.getLevel() + "] ");
while( level.length() < 15 ) /* extend for tabby display */
level.append(" ");
StringBuilder name = new StringBuilder(record.getLoggerName()).append(": ");
while( name.length() < 15 ) /* extend for tabby display */
name.append(" ");
String thread = Thread.currentThread().getName();
if( thread.length() > 18 ) /* trim if too long */
thread = thread.substring( 0, 16 ) + "...";
else {
StringBuilder sb = new StringBuilder(thread);
while( sb.length() < 18 ) /* extend for tabby display */
sb.append(" ");
thread = sb.insert( 0, "Thread " ).toString();
}
final String message = "\"" + record.getMessage() + "\" ";
return level + time + thread + name + clickable + message + "\n";
}
};
ch.setFormatter( formatter );
ch.setLevel( Level.ALL );
} catch( final SecurityException e ) {
e.printStackTrace();
}
return logger;
}
Notice this outputs to the console, you can change that, see http://docs.oracle.com/javase/1.4.2/docs/api/java/util/logging/Logger.html for more information on that.
Now, the following will probably do what you want. It will go through all causes of a Throwable and save it in a String. Note that this does not use StringBuilder
, so you can optimize by changing it.
Throwable e = ...
String detail = e.getClass().getName() + ": " + e.getMessage();
for( final StackTraceElement s : e.getStackTrace() )
detail += "\n\t" + s.toString();
while( ( e = e.getCause() ) != null ) {
detail += "\nCaused by: ";
for( final StackTraceElement s : e.getStackTrace() )
detail += "\n\t" + s.toString();
}

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.
If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%
. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE
echo %WORKSPACE%
If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!
. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion
to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &
, &&
, or ||
are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.
setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
set WORKSPACE=AFTER
echo Normal Expansion = %WORKSPACE%
echo Delayed Expansion = !WORKSPACE!
)
The output of the above is
Normal Expansion = BEFORE
Delayed Expansion = AFTER
Use HELP SET
or SET /?
from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.
For testing, a quick-dirty way including setting log level:
org.apache.log4j.BasicConfigurator.configure();
org.apache.log4j.Logger.getRootLogger().setLevel(org.apache.log4j.Level.WARN);
// set to Level.DEBUG for full, or Level.OFF..
If Source Date format isn't consistent there is some problem
with substr
function, e.g.:
1/1/2017 or 1/11/2017 or 11/11/2017 or 1/1/17 etc.
So I followed a different apporach using a temporary table. This snippet outputs 'YYYY-MM-DD' + time if exists.
Note that this version accepts Day/Month/Year format. If you want Month/Day/Year
swap the first two variables DayPart
and MonthPart
. Also, two year dates '44-'99 assumes 1944-1999 whereas '00-'43 assumes 2000-2043.
BEGIN;
CREATE TEMP TABLE [DateconvertionTable] (Id TEXT PRIMARY KEY, OriginalDate TEXT , SepA INTEGER, DayPart TEXT,Rest1 TEXT, SepB INTEGER, MonthPart TEXT, Rest2 TEXT, SepC INTEGER, YearPart TEXT, Rest3 TEXT, NewDate TEXT);
INSERT INTO [DateconvertionTable] (Id,OriginalDate) SELECT SourceIdColumn, SourceDateColumn From [SourceTable];
--day Part (If day is first)
UPDATE [DateconvertionTable] SET SepA=instr(OriginalDate ,'/');
UPDATE [DateconvertionTable] SET DayPart=substr(OriginalDate,1,SepA-1) ;
UPDATE [DateconvertionTable] SET Rest1=substr(OriginalDate,SepA+1);
--Month Part (If Month is second)
UPDATE [DateconvertionTable] SET SepB=instr(Rest1,'/');
UPDATE [DateconvertionTable] SET MonthPart=substr(Rest1, 1,SepB-1);
UPDATE [DateconvertionTable] SET Rest2=substr(Rest1,SepB+1);
--Year Part (3d)
UPDATE [DateconvertionTable] SET SepC=instr(Rest2,' ');
--Use Cases In case of time string included
UPDATE [DateconvertionTable] SET YearPart= CASE WHEN SepC=0 THEN Rest2 ELSE substr(Rest2,1,SepC-1) END;
--The Rest considered time
UPDATE [DateconvertionTable] SET Rest3= CASE WHEN SepC=0 THEN '' ELSE substr(Rest2,SepC+1) END;
-- Convert 1 digit day and month to 2 digit
UPDATE [DateconvertionTable] SET DayPart=0||DayPart WHERE CAST(DayPart AS INTEGER)<10;
UPDATE [DateconvertionTable] SET MonthPart=0||MonthPart WHERE CAST(MonthPart AS INTEGER)<10;
--If there is a need to convert 2 digit year to 4 digit year, make some assumptions...
UPDATE [DateconvertionTable] SET YearPart=19||YearPart WHERE CAST(YearPart AS INTEGER)>=44 AND CAST(YearPart AS INTEGER)<100;
UPDATE [DateconvertionTable] SET YearPart=20||YearPart WHERE CAST(YearPart AS INTEGER)<44 AND CAST(YearPart AS INTEGER)<100;
UPDATE [DateconvertionTable] SET NewDate = YearPart || '-' || MonthPart || '-' || DayPart || ' ' || Rest3;
UPDATE [SourceTable] SET SourceDateColumn=(Select NewDate FROM DateconvertionTable WHERE [DateconvertionTable].id=SourceIdColumn);

You use ttk.Frame
, bg
option does not work for it. You should create style and apply it to the frame.
from tkinter import *
from tkinter.ttk import *
root = Tk()
s = Style()
s.configure('My.TFrame', background='red')
mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()
This will do what you want. Fixed sides with 50px-width, and the content fills the remaining area.
<div style="width:100%;">
<div style="width: 50px; float: left;">Left Side</div>
<div style="width: 50px; float: right;">Right Side</div>
<div style="margin-left: 50px; margin-right: 50px;">Content Goes Here</div>
</div>
Why are you doing a group by on an update statement? Are you sure that's not the part that's causing the query to fail? Try this:
update
MasterTbl
set
TotalX = Sum(DetailTbl.X),
TotalY = Sum(DetailTbl.Y),
TotalZ = Sum(DetailTbl.Z)
from
DetailTbl
where
DetailTbl.MasterID = MasterID

I suggest using Vladimir Keleshev's pep257 Python program to check your docstrings against PEP-257 and the Numpy Docstring Standard for describing parameters, returns, etc.
pep257 will report divergence you make from the standard and is called like pylint and pep8.
Since 2011a, the recommended way is:
booleanIndex = strcmp('KU', strs)
If you want to get the integer index (which you often don't need), you can use:
integerIndex = find(booleanIndex);
strfind
is deprecated, so try not to use it.
Install cscope
. It works very much like ctags
but more powerful. To go to definition, instead of Ctrl + ], do Ctrl + \ + g. Of course you may use both concurrently. But with a big project (say Linux kernel), cscope is miles ahead.
textView.setTypeface(null, Typeface.BOLD_ITALIC);
textView.setTypeface(null, Typeface.BOLD);
textView.setTypeface(null, Typeface.ITALIC);
textView.setTypeface(null, Typeface.NORMAL);
To keep the previous typeface
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC)
Reasons of ignoring these argument is permanent generation has been removed in HotSpot for JDK8 because of following drawbacks
The Permanent Generation (PermGen) space has completely been removed and is kind of replaced by a new space called Metaspace. The consequences of the PermGen removal is that obviously the PermSize and MaxPermSize JVM arguments are ignored and you will never get a java.lang.OutOfMemoryError: PermGen error.
Advantages of MetaSpace
Metaspace Tuning
The maximum metaspace size can be set using the -XX:MaxMetaspaceSize flag, and the default is unlimited, which means that only your system memory is the limit. The -XX:MetaspaceSize tuning flag defines the initial size of metaspace If you don’t specify this flag, the Metaspace will dynamically re-size depending of the application demand at runtime.
Change enables other optimizations and features in the future
There is improved GC performace also.
A slightly more efficient version of the bytes2String method is
private static final char[] hex = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
private static String byteArray2Hex(byte[] bytes) {
StringBuilder sb = new StringBuilder(bytes.length * 2);
for (final byte b : bytes) {
sb.append(hex[(b & 0xF0) >> 4]);
sb.append(hex[b & 0x0F]);
}
return sb.toString();
}
Another option is to use \dfrac instead of \frac, which makes the whole fraction larger and hence more readable.
And no, I don't know if there is an option to get something in between \frac and \dfrac, sorry.
Just to add an example with parameters:
class B(A):
def __init__(self, x, y, z):
A.__init__(self, x, y)
Given a derived class B that requires the variables x, y, z to be defined, and a superclass A that requires x, y to be defined, you can call the static method init of the superclass A with a reference to the current subclass instance (self) and then the list of expected arguments.
It only comes when your list or dictionary not available in the local function.
In addition to what was said by Howard
You have to keep in mind that Google encodes spaces as +
To avoid this, the ulr must be encoded in RFC 3986, which means spaces encoded at %20
, for example:
https://example.com/My Folder/image 1.jpg
tohttps://example.com/My%20Folder/image%201.jpg
Or, alternatively, you could use Operator module. More detailed information is here Python docs
import operator
import numpy as np
import pandas as pd
np.random.seed(0)
df = pd.DataFrame(np.random.randn(5,3), columns=list('ABC'))
df.loc[operator.or_(df.C > 0.25, df.C < -0.25)]
A B C

In modern browsers, you might want to check out the Intersection Observer API which provides the following benefits:
Intersection Observer is on its way to being a full-fledged standard and is already supported in Chrome 51+, Edge 15+ and Firefox 55+ and is under development for Safari. There's also a polyfill available.
There are some issues with the answer provided by Dan that might make it an unsuitable approach for some situations. Some of these issues are pointed out in his answer near the bottom, that his code will give false positives for elements that are:
clip
propertyThese limitations are demonstrated in the following results of a simple test:
isElementVisible()
Here's a solution to those problems, with the test result below and an explanation of some parts of the code.
function isElementVisible(el) {
var rect = el.getBoundingClientRect(),
vWidth = window.innerWidth || document.documentElement.clientWidth,
vHeight = window.innerHeight || document.documentElement.clientHeight,
efp = function (x, y) { return document.elementFromPoint(x, y) };
// Return false if it's not in the viewport
if (rect.right < 0 || rect.bottom < 0
|| rect.left > vWidth || rect.top > vHeight)
return false;
// Return true if any of its four corners are visible
return (
el.contains(efp(rect.left, rect.top))
|| el.contains(efp(rect.right, rect.top))
|| el.contains(efp(rect.right, rect.bottom))
|| el.contains(efp(rect.left, rect.bottom))
);
}
Passing test: http://jsfiddle.net/AndyE/cAY8c/
And the result:
This method is not without its own limitations, however. For instance, an element being tested with a lower z-index than another element at the same location would be identified as hidden even if the element in front doesn't actually hide any part of it. Still, this method has its uses in some cases that Dan's solution doesn't cover.
Both element.getBoundingClientRect()
and document.elementFromPoint()
are part of the CSSOM Working Draft specification and are supported in at least IE 6 and later and most desktop browsers for a long time (albeit, not perfectly). See Quirksmode on these functions for more information.
contains()
is used to see if the element returned by document.elementFromPoint()
is a child node of the element we're testing for visibility. It also returns true if the element returned is the same element. This just makes the check more robust. It's supported in all major browsers, Firefox 9.0 being the last of them to add it. For older Firefox support, check this answer's history.
If you want to test more points around the element for visibility-ie, to make sure the element isn't covered by more than, say, 50%-it wouldn't take much to adjust the last part of the answer. However, be aware that it would probably be very slow if you checked every pixel to make sure it was 100% visible.
The javascript built-in reduce for Arrays is not a standard, but you can use underscore.js:
var data = _.range(10);
var sum = _(data).reduce(function(memo, i) {return memo + i});
which becomes
var sumMyData = _(myData).reduce(function(memo, i) {return memo + i[1]}, 0);
for your case. Have a look at this fiddle also.
For HttpEntity
, the below answer works
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");
HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);
ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );
For reference: How to POST form data with Spring RestTemplate?
Swift
let indexpath = IndexPath(row: 0, section: 0)
if let cell = tableView.cellForRow(at: indexPath) as? <UITableViewCell or CustomCell> {
cell.backgroundColor = UIColor.red
}
Set<String> stringSet= new HashSet<>();
String[] s = (String[])stringSet.toArray();
Specify the ax
argument to matplotlib.pyplot.colorbar()
, e.g.
import numpy as np
import matplotlib.pyplot as plt
fig, ax = plt.subplots(2, 2)
for i in range(2):
for j in range(2):
data = np.array([[i, j], [i+0.5, j+0.5]])
im = ax[i, j].imshow(data)
plt.colorbar(im, ax=ax[i, j])
plt.show()
As per the documentation, you need to specify true
as the second argument if you want an associative array instead of an object from json_decode
. This would be the code:
$result = json_decode($jsondata, true);
If you want integer
keys instead of whatever the property names are:
$result = array_values(json_decode($jsondata, true));
However, with your current decode you just access it as an object:
print_r($obj->Result);
I had to write a simple script for a carousel to detect swipe left or right.
I utilised Pointer Events instead of Touch Events.
I hope this is useful to individuals and I welcome any insights to improve my code; I feel rather sheepish to join this thread with significantly superior JS developers.
function getSwipeX({elementId}) {
this.e = document.getElementsByClassName(elementId)[0];
this.initialPosition = 0;
this.lastPosition = 0;
this.threshold = 200;
this.diffInPosition = null;
this.diffVsThreshold = null;
this.gestureState = 0;
this.getTouchStart = (event) => {
event.preventDefault();
if (window.PointerEvent) {
this.e.setPointerCapture(event.pointerId);
}
return this.initalTouchPos = this.getGesturePoint(event);
}
this.getTouchMove = (event) => {
event.preventDefault();
return this.lastPosition = this.getGesturePoint(event);
}
this.getTouchEnd = (event) => {
event.preventDefault();
if (window.PointerEvent) {
this.e.releasePointerCapture(event.pointerId);
}
this.doSomething();
this.initialPosition = 0;
}
this.getGesturePoint = (event) => {
this.point = event.pageX
return this.point;
}
this.whatGestureDirection = (event) => {
this.diffInPosition = this.initalTouchPos - this.lastPosition;
this.diffVsThreshold = Math.abs(this.diffInPosition) > this.threshold;
(Math.sign(this.diffInPosition) > 0) ? this.gestureState = 'L' : (Math.sign(this.diffInPosition) < 0) ? this.gestureState = 'R' : this.gestureState = 'N';
return [this.diffInPosition, this.diffVsThreshold, this.gestureState];
}
this.doSomething = (event) => {
let [gestureDelta,gestureThreshold,gestureDirection] = this.whatGestureDirection();
// USE THIS TO DEBUG
console.log(gestureDelta,gestureThreshold,gestureDirection);
if (gestureThreshold) {
(gestureDirection == 'L') ? // LEFT ACTION : // RIGHT ACTION
}
}
if (window.PointerEvent) {
this.e.addEventListener('pointerdown', this.getTouchStart, true);
this.e.addEventListener('pointermove', this.getTouchMove, true);
this.e.addEventListener('pointerup', this.getTouchEnd, true);
this.e.addEventListener('pointercancel', this.getTouchEnd, true);
}
}
You can call the function using new.
window.addEventListener('load', () => {
let test = new getSwipeX({
elementId: 'your_div_here'
});
})
If you convert a Bash script into a function, you typically replace exit N
with return N
. The code that calls the function will treat the return value the same as it would an exit code from a subprocess.
Using exit
inside the function will force the entire script to end.
In Swift 2 you can do it in this way:
var dictionary: NSDictionary = ...
/* NSDictionary to NSData */
let data = NSKeyedArchiver.archivedDataWithRootObject(dictionary)
/* NSData to NSDictionary */
let unarchivedDictionary = NSKeyedUnarchiver.unarchiveObjectWithData(data!) as! NSDictionary
In Swift 3:
/* NSDictionary to NSData */
let data = NSKeyedArchiver.archivedData(withRootObject: dictionary)
/* NSData to NSDictionary */
let unarchivedDictionary = NSKeyedUnarchiver.unarchiveObject(with: data)

You can use this option provided by dataTable itself using buttons.
dom: 'Bfrtip',
buttons: [
'selectAll',
'selectNone'
]'
Here is a sample code
var tableFaculty = $('#tableFaculty').DataTable({
"columns": [
{
data: function (row, type, set) {
return '';
}
},
{data: "NAME"}
],
"columnDefs": [
{
orderable: false,
className: 'select-checkbox',
targets: 0
}
],
select: {
style: 'multi',
selector: 'td:first-child'
},
dom: 'Bfrtip',
buttons: [
'selectAll',
'selectNone'
],
"order": [[0, 'desc']]
});
After speaking with an LDAP expert, it's not possible this way. One query can't search more than one DC or OU.
Your options are:
- Run more then 1 query and parse the result.
- Use a filter to find the desired users/objects based off a different attribute like an AD group or by name.
split_part()
does what you want in one step:
SELECT split_part(col, ',', 1) AS col1
, split_part(col, ',', 2) AS col2
, split_part(col, ',', 3) AS col3
, split_part(col, ',', 4) AS col4
FROM tbl;
Add as many lines as you have items in col
(the possible maximum). Columns exceeding data items will be empty strings (''
).
Like this. Make sure you drop the temp table (at the end of the code block, after you're done with it) or it will error on subsequent runs.
SELECT
tblMEP_Sites.Name AS SiteName,
convert(varchar(10),BillingMonth ,101) AS BillingMonth,

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
For Java Developers:
As @Niels said you have to place in values-v21/styles.xml:
<item name="android:statusBarColor">@color/black</item>
But add tools:targetApi="lollipop"
if you want single styles.xml, like:
<item name="android:statusBarColor" tools:targetApi="lollipop">@color/black</item>
For Kotlin Developers:
window.statusBarColor = ContextCompat.getColor(this, R.color.color_name)
setState is asynchronous. You can use callback method to get updated state.
changeHandler(event) {
this.setState({ yourName: event.target.value }, () =>
console.log(this.state.yourName));
}
I was readying this solutions and this example may help.
My database have two tables (email and credit_card) with primary keys for their IDs. Another table (client) refers to this tables IDs as foreign keys. I have a reason to have the email apart from the client data.
First I insert the row data for the referenced tables (email, credit_card) then you get the ID for each, those IDs are needed in the third table (client).
If you don't insert first the rows in the referenced tables, MySQL wont be able to make the correspondences when you insert a new row in the third table that reference the foreign keys.
If you first insert the referenced rows for the referenced tables, then the row that refers to foreign keys, no error occurs.
Hope this helps.
If this is your dataArray
:
var dataArray = [{"id":28,"class":"Sweden"}, {"id":56,"class":"USA"}, {"id":89,"class":"England"}];
then:
$(jQuery.parseJSON(JSON.stringify(dataArray))).each(function() {
var ID = this.id;
var CLASS = this.class;
});
You can use method reference like this:
user.ifPresent(ClassNameWhereMethodIs::doSomethingWithUser);
Method ifPresent()
get Consumer
object as a paremeter and (from JavaDoc): "If a value is present, invoke the specified consumer with the value." Value it is your variable user
.
Or if this method doSomethingWithUser
is in the User
class and it is not static
, you can use method reference like this:
user.ifPresent(this::doSomethingWithUser);
Both setInterval
and requestAnimationFrame
don't work when tab is inactive or work but not at the right periods. A solution is to use another source for time events. For example web sockets or web workers are two event sources that work fine while tab is inactive. So no need to move all of your code to a web worker, just use worker as a time event source:
// worker.js
setInterval(function() {
postMessage('');
}, 1000 / 50);
.
var worker = new Worker('worker.js');

I suppose that
std::to_string(i)
could do the job, it's an overloaded function, it could be any numeric type such as int, double or float
C++ compilers process their input once. Each class you use must have been defined first. You use MyMessageBox
before you define it. In this case, you can simply swap the two class definitions.
In Clean Code, Robert C. Martin devoted four pages to the subject. Here's the gist:
The ideal number of arguments for a function is zero (niladic). Next comes one (monadic), followed closely by two (dyadic). Three arguments (triadic) should be avoided where possible. More than three (polyadic) requires very special justification -- and then shouldn't be used anyway.
var cumulativeOffset = function(element) {
var top = 0, left = 0;
do {
top += element.offsetTop || 0;
left += element.offsetLeft || 0;
element = element.offsetParent;
} while(element);
return {
top: top,
left: left
};
};

They are synonyms, no difference at all.Decimal and Numeric data types are numeric data types with fixed precision and scale.
-- Initialize a variable, give it a data type and an initial value
declare @myvar as decimal(18,8) or numeric(18,8)----- 9 bytes needed
-- Increse that the vaue by 1
set @myvar = 123456.7
--Retrieve that value
select @myvar as myVariable

Generic types is a compile time abstraction. At runtime all maps will have the same type Map<Object, Object>
. So if you are sure that values are strings, you can cheat on java compiler:
Map<String, Object> m1 = new HashMap<String, Object>();
Map<String, String> m2 = (Map) m1;
Copying keys and values from one collection to another is redundant. But this approach is still not good, because it violates generics type safety. May be you should reconsider your code to avoid such things.
There is a code here that does it.
The trick is at this line:
title.setVisibility(View.GONE);

The best way to create internal links (related with sections) is create list but instead of link, put #section
or #section-title
if the header includes spaces.
Markdown
Go to section
* [Hello](#hello)
* [Hello World](#hello-world)
* [Another section](#new-section) <-- it's called 'Another section' in this list but refers to 'New section'
## Hello
### Hello World
## New section
List preview
Go to section
Hello <-- [Hello](#hello) -- go to `Hello` section
Hello World <-- [Hello World](#hello world) -- go to `Hello World` section
Another section <-- [Another section](#new-section) -- go to `New section`
HTML
<p>Go to section</p>
<ul>
<li><a href="#hello">Hello</a></li>
<li><a href="#hello-world">Hello World</a></li>
<li><a href="#new-section">Another section</a> <– it’s called ‘Another section’ in this list but refers to ‘New section’</li>
</ul>
<h2 id="hello">Hello</h2>
<h3 id="hello-world">Hello World</h3>
<h2 id="new-section">New section</h2>
It doesn't matter whether it's h1
, h2
, h3
, etc. header, you always refer to it using just one #
.
All references in section list should be converted to lowercase text as it is shown in the example above.
The link to the section should be lowercase. It won't work otherwise. This technique works very well for all Markdown variants, also MultiMarkdown.
Currently I'm using the Pandoc to convert documents format. It's much better than MultiMarkdown.
Test Pandoc here
int w =0 , l =0, d=0, i=0;

Go to Menu Tool -> SQL Output, Run the PL/SQL statement, the output will show on SQL Output panel.
Here's a better option:
git remote set-head -a origin
From the documentation:
With -a, the remote is queried to determine its HEAD, then $GIT_DIR/remotes//HEAD is set to the same branch. e.g., if the remote HEAD is pointed at next, "git remote set-head origin -a" will set $GIT_DIR/refs/remotes/origin/HEAD to refs/remotes/origin/next. This will only work if refs/remotes/origin/next already exists; if not it must be fetched first.
This has actually been around quite a while (since v1.6.3); not sure how I missed it!
The example code below demonstrates this in detail.
<%@page import="java.sql.*, java.io.*,listresult"%> //import the required library
<%
String label = request.getParameter("label"); // retrieving a variable from a previous page
Connection dbc = null; //Make connection to the database
Class.forName("com.mysql.jdbc.Driver");
dbc = DriverManager.getConnection("jdbc:mysql://localhost:3306/works", "root", "root");
if (dbc != null)
{
System.out.println("Connection successful");
}
ResultSet rs = listresult.dbresult.func(dbc, label); //This function is in the end. The function is defined in another package- listresult
%>
<form name="demo form" method="post">
<table>
<tr>
<td>
Label Name:
</td>
<td>
<input type="text" name="label" value="<%=rs.getString("labelname")%>">
</td>
<td>
<select name="label">
<option value="">SELECT</option>
<% while (rs.next()) {%>
<option value="<%=rs.getString("lname")%>"><%=rs.getString("lname")%>
</option>
<%}%>
</select>
</td>
</tr>
</table>
</form>
//The function:
public static ResultSet func(Connection dbc, String x)
{
ResultSet rs = null;
String sql;
PreparedStatement pst;
try
{
sql = "select lname from demo where label like '" + x + "'";
pst = dbc.prepareStatement(sql);
rs = pst.executeQuery();
}
catch (Exception e)
{
e.printStackTrace();
String sqlMessage = e.getMessage();
}
return rs;
}
I have tried to make this example as detailed as possible. Do ask if you have any queries.
You can use a for-loop to address a field with $i:
ls -l | awk '{for(i=3 ; i<8 ; i++) {printf("%s\t", $i)} print ""}'
Error message suggests that the client has closed the connection while the server is still trying to write out a response.
Refer to this link for more details:
Note that %in%
returns a logical vector of TRUE
and FALSE
. To negate it, you can use !
in front of the logical statement:
SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean,
!where_case_travelled_1 %in%
c('Outside Canada','Outside province/territory of residence but within Canada'))
Regarding your original approach with -c(...)
, -
is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")
). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -
.
for counting:
$('.yourClass').length;
should work fine.
storing in a variable is as easy as:
var count = $('.yourClass').length;
select2
has the placeholder
parameter. Use that one
$("#state").select2({
placeholder: "Choose a Country"
});
So what is the URL that Yii::app()->params['pdfUrl']
gives? You say it should be https, but the log shows it's connecting on port 80... which almost no server is setup to accept https connections on. cURL is smart enough to know https should be on port 443... which would suggest that your URL has something wonky in it like: https://196.41.139.168:80/serve/?r=pdf/generatePdf
That's going to cause the connection to be terminated, when the Apache at the other end cannot do https communication with you on that port.
You realize your first $body
definition gets replaced when you set $body
to an array two lines later? {Probably just an artifact of you trying to solve the problem} You're also not encoding the client_url
and client_id
values (the former quite possibly containing characters that need escaping!) Oh and you're appending to $body_str
without first initializing it.
From your verbose output we can see cURL is adding a content-length
header, but... is it correct? I can see some comments out on the internets of that number being wrong (especially with older versions)... if that number was to small (for example) you'd get a connection-reset before all the data is sent. You can manually insert the header:
curl_setopt ($c, CURLOPT_HTTPHEADER,
array("Content-Length: ". strlen($body_str)));
Oh and there's a handy function http_build_query
that'll convert an array of name/value pairs into a URL encoded string for you.
All this rolls up into the final code:
$post=http_build_query(array(
"client_url"=>Yii::app()->params['pdfClientURL'],
"client_id"=>Yii::app()->params['pdfClientID'],
"title"=>$title,
"content"=>$content));
//Open to URL
$c=curl_init(Yii::app()->params['pdfUrl']);
//Send post
curl_setopt ($c, CURLOPT_POST, true);
//Optional: [try with/without]
curl_setopt ($c, CURLOPT_HTTPHEADER, array("Content-Length: ".strlen($post)));
curl_setopt ($c, CURLOPT_POSTFIELDS, $post);
curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($c, CURLOPT_CONNECTTIMEOUT , 0);
curl_setopt ($c, CURLOPT_TIMEOUT , 20);
//Collect result
$pdf = curl_exec ($c);
$curlInfo = curl_getinfo($c);
curl_close($c);
I know this is an old question but I needed a formula for workdays excluding the start date since I have several items and need the days to accumulate correctly.
None of the non-iterative answers worked for me.
I used a defintion like
Number of times midnight to monday, tuesday, wednesday, thursday and friday is passed
(others might count midnight to saturday instead of monday)
I ended up with this formula
SELECT DATEDIFF(day, @StartDate, @EndDate) /* all midnights passed */
- DATEDIFF(week, @StartDate, @EndDate) /* remove sunday midnights */
- DATEDIFF(week, DATEADD(day, 1, @StartDate), DATEADD(day, 1, @EndDate)) /* remove saturday midnights */
After some research and testing, I found that I had some misunderstandings about the lifetime of Docker containers. Simply restarting a container doesn't make Docker use a new image, when the image was rebuilt in the meantime. Instead, Docker is fetching the image only before creating the container. So the state after running a container is persistent.
Therefore, rebuilding and restarting isn't enough. I thought containers works like a service: Stopping the service, do your changes, restart it and they would apply. That was my biggest mistake.
Because containers are permanent, you have to remove them using docker rm <ContainerName>
first. After a container is removed, you can't simply start it by docker start
. This has to be done using docker run
, which itself uses the latest image for creating a new container-instance.
With this knowledge, it's comprehensible why storing data in containers is qualified as bad practice and Docker recommends data volumes/mounting host directorys instead: Since a container has to be destroyed to update applications, the stored data inside would be lost too. This cause extra work to shutdown services, backup data and so on.
So it's a smart solution to exclude those data completely from the container: We don't have to worry about our data, when its stored safely on the host and the container only holds the application itself.
-rf
may not really help youThe docker run
command, has a Clean up switch called -rf
. It will stop the behavior of keeping docker containers permanently. Using -rf
, Docker will destroy the container after it has been exited. But this switch has two problems:
-d
switchWhile the -rf
switch is a good option to save work during development for quick tests, it's less suitable in production. Especially because of the missing option to run a container in the background, which would mostly be required.
We can bypass those limitations by simply removing the container:
docker rm --force <ContainerName>
The --force
(or -f
) switch which use SIGKILL on running containers. Instead, you could also stop the container before:
docker stop <ContainerName>
docker rm <ContainerName>
Both are equal. docker stop
is also using SIGTERM. But using --force
switch will shorten your script, especially when using CI servers: docker stop
throws an error if the container is not running. This would cause Jenkins and many other CI servers to consider the build wrongly as failed. To fix this, you have to check first if the container is running as I did in the question (see containerRunning
variable).
According to this new knowledge, I fixed my script in the following way:
#!/bin/bash
imageName=xx:my-image
containerName=my-container
docker build -t $imageName -f Dockerfile .
echo Delete old container...
docker rm -f $containerName
echo Run new container...
docker run -d -p 5000:5000 --name $containerName $imageName
This works perfectly :)
You can remove the "bullets" by setting the "list-style-type: none;" Like

Here's a hint, you have a graph of nodes in the linked list, and you always keep a reference to head which is the first node in the linkedList.
next points to the next node in the linkedlist, so when next is null you are at the end of the list.
Try this:
ServersTable.Columns.Clear();
ServersTable.DataSource = SBind;
If you don't want to clear all the existing columns, you have to set DataPropertyName
for each existing column like this:
for (int i = 0; i < ServersTable.ColumnCount; ++i) {
DTable.Columns.Add(new DataColumn(ServersTable.Columns[i].Name));
ServersTable.Columns[i].DataPropertyName = ServersTable.Columns[i].Name;
}
For
@Url.Action
<a href="@Url.Action("Action", "Controller")" target="_blank">Link Text</a>
Well, here is one solution I ended up with, but I hope there's a more elegant one...
StringBuilder result = new StringBuilder();
for(int i=0; i<name.length(); i++) {
char tmpChar = name.charAt( i );
if (Character.isLetterOrDigit( tmpChar) || tmpChar == '_' ) {
result.append( tmpChar );
}
}
result
ends up with the desired result...
If you don't want the event to be continuous (if you want the user to have to release the key each time), change onkeydown
to onkeyup
window.onkeydown = function (e) {
var code = e.keyCode ? e.keyCode : e.which;
if (code === 38) { //up key
alert('up');
} else if (code === 40) { //down key
alert('down');
}
};
This is your config :
log4j.appender.FILE.File=logs/${file.name}
And this error happened :
java.io.FileNotFoundException: logs (Access is denied)
So it seems that the variable file.name
is not set, and java tries to write to the directory logs
.
You can force the value of your variable ${file.name}
calling maven with this option -D :
mvn clean test -Dfile.name=logfile.log
<select name="foo" id="foo">
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
</select>
<input type="button" id="button" value="Button" />
});
<script> ("#foo").val() </script>
which returns 1 if you have selected a and so on..
With SemaphoreSlim
you can achieve parallelism control.
var bag = new ConcurrentBag<object>();
var maxParallel = 20;
var throttler = new SemaphoreSlim(initialCount: maxParallel);
var tasks = myCollection.Select(async item =>
{
try
{
await throttler.WaitAsync();
var response = await GetData(item);
bag.Add(response);
}
finally
{
throttler.Release();
}
});
await Task.WhenAll(tasks);
var count = bag.Count;
That cannot be done in excel 2007. The list must be in the same sheet as your data. It might work in later versions though.
I had a similar problem in .NET
app in Internet Explorer.
I solved the problem adding the certificate (VeriSign Class 3 certificate in my case) to trusted editors certificates.
Go to Internet Options-> Content -> Publishers and import it
You can get the certificate if you export it from:
Internet Options-> Content -> Certificates -> Intermediate Certification Authorities -> VeriSign Class 3 Public Primary Certification Authority - G5

From Dockerfile reference:
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.The
ENV
instruction sets the environment variable<key>
to the value<value>
.
The environment variables set usingENV
will persist when a container is run from the resulting image.
So if you need build-time customization, ARG
is your best choice.
If you need run-time customization (to run the same image with different settings), ENV
is well-suited.
If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable
Given the number of combinations involved, using ENV
to set those features at runtime is best here.
But you can combine both by:
ARG
ARG
as an ENV
That is, with a Dockerfile including:
ARG var
ENV var=${var}
You can then either build an image with a specific var
value at build-time (docker build --build-arg var=xxx
), or run a container with a specific runtime value (docker run -e var=yyy
)
We can accomplish the task in two simple way one is using Json.NET dll and another is by using StringBuilder class.
Using Newtonsoft Json.NET
string JSONresult;

Suppose you want to install Laravel Collective. It's currently at version 6.x but you want version 5.8. You can run the following command:
composer require "laravelcollective/html":"^5.8.0"
A good example is shown here in the documentation: https://laravelcollective.com/docs/5.5/html
staticmethod
objects apparently have a __func__
attribute storing the original raw function (makes sense that they had to). So this will work:
class Klass(object):
@staticmethod # use as decorator
def stat_func():
return 42
_ANS = stat_func.__func__() # call the staticmethod
def method(self):
ret = Klass.stat_func()
return ret
As an aside, though I suspected that a staticmethod object had some sort of attribute storing the original function, I had no idea of the specifics. In the spirit of teaching someone to fish rather than giving them a fish, this is what I did to investigate and find that out (a C&P from my Python session):
>>> class Foo(object):
... @staticmethod
... def foo():
... return 3
... global z
... z = foo
>>> z
<staticmethod object at 0x0000000002E40558>
>>> Foo.foo
<function foo at 0x0000000002E3CBA8>
>>> dir(z)
['__class__', '__delattr__', '__doc__', '__format__', '__func__', '__get__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
>>> z.__func__
<function foo at 0x0000000002E3CBA8>
Similar sorts of digging in an interactive session (dir
is very helpful) can often solve these sorts of question very quickly.
I had this line in my AndroidManifest.xml
<activity
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
android:label="@string/app_name" android:name="Project Name"
android:theme="@android:style/Theme.Black.NoTitleBar">
Which I changed to (just added android:screenOrientation="portrait"
)
<activity
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
android:label="@string/app_name" android:name="Project Name"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.Black.NoTitleBar">
This fixed things for me.
I've come across it several different times and every time it was always some error with either duplicating a tab name or in this current case it just occurred because I simply had a typo in the get_Range
where I tried to get a Cell by number and number instead of the letter and number.
Drove me crazy because the error pointed me to a few lines down but I had commented out all of the creation of the other sheets above the "error line" and the ones in the line and below were created with no issue.
Happened to scan up a few lines above and saw that I put 6 + lastword, C + lastrow
in my get_Range
statement and of course you can't have a cell starting with a number it's always letter than number.
Apache Camel is a Java framework for Enterprise integration. Eg:- if you are building a web application which interacts with many vendor API's we can use the camel as the External integration tool. We can do more with it based on the use case. Camel in Action from Manning publications is a great book for learning Camel. The integrations can be defined as below.
Java DSL
from("jetty://0.0.0.0:8080/searchProduct").routeId("searchProduct.products").threads()
.log(LoggingLevel.INFO, "searchProducts request Received with body: ${body}")
.bean(Processor.class, "createSearchProductsRequest").removeHeaders("CamelHttp*")
.setHeader(Exchange.HTTP_METHOD, constant(org.apache.camel.component.http4.HttpMethods.POST))
.to("http4://" + preLiveBaseAPI + searchProductsUrl + "?apiKey=" + ApiKey
+ "&bridgeEndpoint=true")
.bean(Processor.class, "buildResponse").log(LoggingLevel.INFO, "Search products finished");
This is to just create a REST API endpoint which in turn calls an external API and sends the request back
Spring DSL
<route id="GROUPS-SHOW">
