Another workaround would be to spoof your IP using some sort of Public VPN or Tor network. This would be assuming the rate-limiting on the server at IP level.
There is a brief blog post demonstrating a way to use tor along with urllib2:
Use money-rails gem. It nicely handles money and currencies in your model and also has a bunch of helpers to format your prices.

I have been trying to do the same myself. What I found was that the "Export Ant Buildfile" gets kicked off in the org.eclipse.ant.internal.ui.datatransfer.AntBuildfileExportPage.java file. This resides in the org.eclipse.ant.ui plugin.
To view the source, use the Plug-in Development perspective and open the Plug-ins view. Then right-click on the org.eclipse.ant.ui plugin and select import as > source project.
My plan is to create a Java program to programmatically kick off the ant buildfile generation and call this in an Ant file every time I build by adding the ant file to the builders of my projects (Right-click preferences on a projet, under the builders tab).
You have writer.close();
in your code. So bash receives EOF on its stdin
and exits. Then you get Broken pipe
when trying to read from the stdout
of the defunct bash.
Sometimes, 0 might not be appropriate, but sometimes 1 is also not appropriate. Sometimes a jump from 0 to 100,000,000 described as 1 or 100-percent change might also be misleading. 100,000,000 percent might be appropriate in that scenario. It depends on what kind of conclusions you intend to draw based on the percentages or ratios.
For example, a very small-selling item moving from 2-4 sold and a very large-selling item changing from 1,000,000 to 2,000,000 sold might mean very different things to an analyst or to management, but would both come through as 100% or 1 change.
It might be easier to isolate NULL values than to scour over a bunch of 0% or 100% rows mixed with legitimate data. Often, a 0 in the denominator can indicate an error or missing value, and you might not want to just fill in an arbitrary value just to make your dataset look tidy.

You can do it in following ways;
You can go to control panel/cpanel and add host % It means now the database server can be accessed from your local machine. Now you can install and use MySQL Administrator or Navicat to import and export database with out using PHP-Myadmin, I used it several times to upload 200 MB to 500 MB of data with no issues
Use gzip, bzip2 compressions for exporting and importing. I am using PEA ZIP software (free) in Windows. Try to avoid Winrar and Winzip
Use MySQL Splitter that splits up the sql file into several parts. In my personal suggestion, Not recommended
Using PHP INI setting (dynamically change the max upload and max execution time) as already mentioned by other friends is fruitful but not always.
netifaces is a good module to use for getting the mac address (and other addresses). It's crossplatform and makes a bit more sense than using socket or uuid.
>>> import netifaces
>>> netifaces.interfaces()
['lo', 'eth0', 'tun2']
>>> netifaces.ifaddresses('eth0')[netifaces.AF_LINK]
[{'addr': '08:00:27:50:f2:51', 'broadcast': 'ff:ff:ff:ff:ff:ff'}]
Put quotes around the <?php echo $cname; ?>
to make sure Javascript accepts it as a string, also consider escaping.
If one or both of the files you wish to compare isn't in an Eclipse project:

I'm sure all of these algorithms are great, but you cannot verify that a card number is valid just by running an algorithm on it.
Algorithms make sure the format is correct and its checksums are valid. However, they do not guarantee the bank will accept the card... For that, you need to actually pass the card number to your bank for approval.
innerHTML
sets the text (including html elements) inside an element. Normally we use it for elements like div, span etc to insert other html elements inside it.
For your case you want to set the value of an input element. So you should use the value
attribute.
Change innerHTML
to value
document.getElementById('add').value = sum;
While this particular example is for a multiple file upload, it gives the general information one needs:

As far as acting upon a file upon /download/ this is not a Javascript question -- but rather a server configuration. If a user does not have something installed to open PDF or XLS files, their only choice will be to download them.
As pointed by Larcho, starting from API level 10, you can use BitmapRegionDecoder
to load specific regions from an image and with that, you can accomplish to show a large image in high resolution by allocating in memory just the needed regions. I've recently developed a lib that provides the visualisation of large images with touch gesture handling. The source code and samples are available here.
You can also use Scanner :
Scanner s = new Scanner(MyString);
s.nextInt();
Use phpMyAdmin in this way:
Database View => Check All (tables) => Empty
If you want to ignore foreign key checks, you can uncheck the box that says:
[ ] Enable foreign key checks
You'll need to be running atleast version 4.5.0 or higher to get this checkbox.
Its not MySQL CLI-fu, but hey, it works!
without changing your index mappings you could do a simple prefix query that will do partial searches like you are hoping for
ie.

"query": {
"prefix" : { "name" : "Doe" }
}

The Global Assembly Cache (GAC) is a folder in Windows directory to store the .NET assemblies that are specifically designated to be shared by all applications executed on a system. Assemblies can be shared among multiple applications on the machine by registering them in global Assembly cache(GAC). GAC is a machine wide a local cache of assemblies maintained by the .NET Framework.

Put your CSS in your bundle's Resource/public/css
directory, and your images in say Resource/public/img
.
Change assetic paths to the form 'bundles/mybundle/css/*.css'
, in your layout.
In config.yml
, add rule css_rewrite
to assetic:
assetic:
filters:
cssrewrite:
apply_to: "\.css$"
Now install assets and compile with assetic:
$ rm -r app/cache/* # just in case
$ php app/console assets:install --symlink
$ php app/console assetic:dump --env=prod
This is good enough for the development box, and --symlink
is useful, so you don't have to reinstall your assets (for example, you add a new image) when you enter through app_dev.php
.
For the production server, I just removed the '--symlink' option (in my deployment script), and added this command at the end:
$ rm -r web/bundles/*/css web/bundles/*/js # all this is already compiled, we don't need the originals
All is done. With this, you can use paths like this in your .css files: ../img/picture.jpeg
A slightly simpler method:
>>> t = ((1, 'a'),(2, 'b'))
>>> dict(map(reversed, t))
{'a': 1, 'b': 2}
Shallow copies duplicate as little as possible. A shallow copy of a collection is a copy of the collection structure, not the elements. With a shallow copy, two collections now share the individual elements.
Deep copies duplicate everything. A deep copy of a collection is two collections with all of the elements in the original collection duplicated.
There are several ways you can achieve this. One would be something like:
for filepath in /path/to/dir/*
do
filename=$(basename $filepath)
... whatever you want to do with the file here
done
You can use VBA - something like
Range("A1:A6").Interior.Color = RGB(127,187,199)
Just pass in the cell value.
public static byte[] readResoureStream(String resourcePath) throws IOException {
ByteArrayOutputStream byteArray = new ByteArrayOutputStream();
InputStream in = CreateBffFile.class.getResourceAsStream(resourcePath);
//Create buffer
byte[] buffer = new byte[4096];
for (;;) {
int nread = in.read(buffer);
if (nread <= 0) {
break;
}
byteArray.write(buffer, 0, nread);
}
return byteArray.toByteArray();
}
Charset charset = StandardCharsets.UTF_8;
String content = new String(FileReader.readResoureStream("/resource/...*.txt"), charset);
String lines[] = content.split("\\n");
If you're using ASP.NET 2.0 or greater, you can turn it on in the Web.config file. In the <system.web> section, add the following line:
<httpCookies httpOnlyCookies="true"/>
You need to edit your ~/.ssh/config file. Add something like the following:
Host example.com
Port 1234

To try to improve this Rashid's good answer I'm adding some comments:
The trick is done over the wrapper of the image to be swapped (an 'a' tag this time but maybe another) so the 'hover_image' class has been put there.
Advantages:
Keeping both images url together in the same place helps if they need to be changed.
Seems to work with old navigators too (CSS2 standard).
It's self explanatory.
The hover image is preloaded (no delay after hovering).
You don't need --header "Content-Length: $LENGTH".
curl --request POST --data-binary "@template_entry.xml" $URL
Note that GET request does not support content body widely.
Also remember that POST request have 2 different coding schema. This is first form:
$ nc -l -p 6666 & $ curl --request POST --data-binary "@README" http://localhost:6666 POST / HTTP/1.1 User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6 Host: localhost:6666 Accept: */* Content-Length: 9309 Content-Type: application/x-www-form-urlencoded Expect: 100-continue .. -*- mode: rst; coding: cp1251; fill-column: 80 -*- .. rst2html.py README README.html .. contents::
You probably request this:
-F/--form name=content (HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content- Type multipart/form-data according to RFC2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.
In Android Studio v1.2, it tells you how to fix it:
In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.
When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.
When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).
A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.

You could also use the whitelist method -
var str = $('#Search').val();
var regex = /[^\w\s]/gi;
if(regex.test(str) == true) {
alert('Your search string contains illegal characters.');
}
The regex in this example is digits, word characters, underscores (\w) and whitespace (\s). The caret (^) indicates that we are to look for everything that is not in our regex, so look for things that are not word characters, underscores, digits and whitespace.
Return is how you exit out of a function body. You are using the correct approach.
I suppose, depending on how your application is structured, you could also use throw. That would typically require that your calls to your function are wrapped in a try / catch block.
Here a shortened version of shasan's code, calculating the 95% confidence interval of the mean of array a
:
import numpy as np, scipy.stats as st
st.t.interval(0.95, len(a)-1, loc=np.mean(a), scale=st.sem(a))
But using StatsModels' tconfint_mean
is arguably even nicer:
import statsmodels.stats.api as sms
sms.DescrStatsW(a).tconfint_mean()
The underlying assumptions for both are that the sample (array a
) was drawn independently from a normal distribution with unknown standard deviation (see MathWorld or Wikipedia).
For large sample size n, the sample mean is normally distributed, and one can calculate its confidence interval using st.norm.interval()
(as suggested in Jaime's comment). But the above solutions are correct also for small n, where st.norm.interval()
gives confidence intervals that are too narrow (i.e., "fake confidence"). See my answer to a similar question for more details (and one of Russ's comments here).
Here an example where the correct options give (essentially) identical confidence intervals:
In [9]: a = range(10,14)
In [10]: mean_confidence_interval(a)
Out[10]: (11.5, 9.4457397432391215, 13.554260256760879)
In [11]: st.t.interval(0.95, len(a)-1, loc=np.mean(a), scale=st.sem(a))
Out[11]: (9.4457397432391215, 13.554260256760879)
In [12]: sms.DescrStatsW(a).tconfint_mean()
Out[12]: (9.4457397432391197, 13.55426025676088)
And finally, the incorrect result using st.norm.interval()
:
In [13]: st.norm.interval(0.95, loc=np.mean(a), scale=st.sem(a))
Out[13]: (10.23484868811834, 12.76515131188166)

You just need to convert your dates to UNIX_TIMESTAMP
. You can write your query like this:
SELECT *
FROM eventList
WHERE
date BETWEEN
UNIX_TIMESTAMP('2013/03/26')
AND
UNIX_TIMESTAMP('2013/03/27 23:59:59');
When you don't specify the time, MySQL will assume 00:00:00
as the time for the given date.
Encoding an image to base64 will make it about 30% bigger.
See the details in the wikipedia article about the Data URI scheme, where it states:
Base64-encoded data URIs are 1/3 larger in size than their binary equivalent. (However, this overhead is reduced to 2-3% if the HTTP server compresses the response using gzip)
Early versions of unix measured system time in 1/60 s intervals. This meant that a 32-bit unsigned integer could only represent a span of time less than 829 days. For this reason, the time represented by the number 0
(called the epoch) had to be set in the very recent past. As this was in the early 1970s, the epoch was set to 1971-1-1.
Later, the system time was changed to increment every second, which increased the span of time that could be represented by a 32-bit unsigned integer to around 136 years. As it was no longer so important to squeeze every second out of the counter, the epoch was rounded down to the nearest decade, thus becoming 1970-1-1. One must assume that this was considered a bit neater than 1971-1-1.
Note that a 32-bit signed integer using 1970-1-1 as its epoch can represent dates up to 2038-1-19, on which date it will wrap around to 1901-12-13.

You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.
In the Controller, you can use the javax.json to convert and manipulate this.
Download and add the .jar to the project libs and import the JsonObject.
To create an json object, you can use
JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();
To read it from String, you can use
JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();
Converting both strings to lower-case is usually not a big deal but it would be slow if some of the strings is long. And if you do this in a loop then it would be really bad. For this reason, I would recommend indexOfIgnoreCase
.
I just read in the MySQL documentation that SHOW FULL PROCESSLIST
by default only lists the threads from your current user connection.
Quote from the MySQL SHOW FULL PROCESSLIST documentation:
If you have the PROCESS privilege, you can see all threads.
So you can enable the Process_priv
column in your mysql.user
table. Remember to execute FLUSH PRIVILEGES
afterwards :)
For anyone looking at this now, on systemd systems (in my case, specifically Ubuntu 16.04) there is another limit enforced by the cgroup pids.max parameter.
This is set to 12,288 by default, and can be overriden in /etc/systemd/logind.conf
Other advice still applies including pids_max, threads-max, max_maps_count, ulimits, etc.
You can use conda remove --force
.
The documentation says:
--force Forces removal of a package without removing packages
that depend on it. Using this option will usually
leave your environment in a broken and inconsistent
state

I'm sticking to the shared local data solution mentioned in the question using
localStorage
. It seems to be the best solution in terms of reliability, performance, and browser compatibility.
localStorage
is implemented in all modern browsers.The
storage
event fires when other tabs makes changes tolocalStorage
. This is quite handy for communication purposes.Reference:

you can also connect to database as "normal" user (not postgres):
postgres=# \connect opensim Opensim_Tester localhost;
Password for user Opensim_Tester:
You are now connected to database "opensim" as user "Opensim_Tester" on host "localhost" at port "5432"
If I get you correctly, you want to know when a tab/window is effectively closed. Well, AFAIK the only way in Javascript
to detect that kind of stuffs are onunload
& onbeforeunload
events.
Unfortunately (or fortunately?), those events are also fired when you leave a site over a link
or your browsers back button. So this is the best answer I can give, I don't think you can natively detect a pure close
in Javascript. Correct me if I'm wrong here.
This is sufficient...
xpath xhtmlfile.xhtml '/html/head/title/text()' > titleOfXHTMLPage.txt
For quick and simple solution Try:
set extra data to a boolean value.
extraData={this.state.refresh}
Toggle the value of boolean state when you want to re-render/refresh list
this.setState({
refresh: !this.state.refresh
})
instead of using add() we can use addall()
{ seeAlso.addall(groupDn); }
add adds a single item, while addAll adds each item from the collection one by one. In the end, both methods return true if the collection has been modified. In case of ArrayList this is trivial, because the collection is always modified, but other collections, such as Set, may return false if items being added are already there.

It seems to me that the answer to this question is (at least now) clearly documented on the Safari HTML5 docs:
User Control of Downloads Over Cellular Networks
In Safari on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and autoplay are disabled. No data is loaded until the user initiates it. This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not.
This plays the movie: <input type="button" value="Play" onClick="document.myMovie.play()">
This does nothing on iOS: <body onLoad="document.myMovie.play()">
mysqld --help --verbose is dangerous. You can easily overwrite pidfile for running instance! use it with --pid-file=XYZ

Really good article about it:
I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:
.ui-helper-center {
text-align: center;
}
And then add the ui-helper-center
class to the table cells for which you wish to control the alignment:
<td class="ui-helper-center">Content</td>
EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.
See Gabe's answer for how to include the CSS rule into your page.
Yes. You know that you can put any Object
into the Object
parameter of most JOptionPane.showXXX methods
, and often that Object
happens to be a JPanel
.
In your situation, perhaps you could use a JPanel
that has several JTextFields
in it:
import javax.swing.*;
public class JOptionPaneMultiInput {
public static void main(String[] args) {
JTextField xField = new JTextField(5);
JTextField yField = new JTextField(5);
JPanel myPanel = new JPanel();

what about using "window.screen.width" ?
if (window.screen.width < 800) {
// do something
}
or
if($(window).width() < 800) {
//do something
}
I guess this is the best way because there is a new mobile device every day !
(although I think it's not that supported in old browsers, but give it a try :) )
Good answers, however don't forget about filter()
from dplyr:
patterns <- c("A1", "A9", "A6")
>your_df
FirstName Letter
1 Alex A1
2 Alex A6
3 Alex A7
4 Bob A1
5 Chris A9
6 Chris A6
result <- filter(your_df, grepl(paste(patterns, collapse="|"), Letter))
>result
FirstName Letter
1 Alex A1
2 Alex A6
3 Bob A1
4 Chris A9
5 Chris A6
Starting from freemarker 2.3.7, you can use this syntax :
${(object.attribute)!}
or, if you want display a default text when the attribute is null
:
${(object.attribute)!"default text"}
I also underwent the same issue as Maven doesn't create the settings.xml
file under .m2
folder. What I did was the following and it works smoothly without any issues.
Go to the location where you maven was unzipped.
Direct to following path,
\apache-maven-3.0.4\conf\
and copy the settings.xml
file and paste it inside your .m2
folder.
Now create a maven project.
In case you are working with seaborn plots, instead of Matplotlib, you can save a .png image like this:
Let's suppose you have a matrix
object (either Pandas or NumPy), and you want to take a heatmap:
import seaborn as sb
image = sb.heatmap(matrix) # This gets you the heatmap
image.figure.savefig("C:/Your/Path/ ... /your_image.png") # This saves it
This code is compatible with the latest version of Seaborn. Other code around Stack Overflow worked only for previous versions.
Another way I like is this. I set the size of the next image as follows:
plt.subplots(figsize=(15,15))
And then later I plot the output in the console, from which I can copy-paste it where I want. (Since Seaborn is built on top of Matplotlib, there will not be any problem.)
Most of the answers were good and right for your problem of
so i want to find the difference between date in number of days, how do i find difference in days?
I suggest this very simple and straightforward approach that is guaranteed to give you the correct difference in any time zone:
int difference=
((int)((startDate.getTime()/(24*60*60*1000))
-(int)(endDate.getTime()/(24*60*60*1000))));
And that's it!
One simple solution:
cond1 <- df$sub == 1 & df$day == 2
cond2 <- df$sub == 3 & df$day == 4
df <- df[!(cond1 | cond2),]
Guess this is reallllly late for this. But adding the below config to the app.module imports does the job:
RouterModule.forRoot(routes, { useHash: false })
Referring to the bible:
In Tomcat 6, the CLASSPATH in your environment is ignored. In setclasspath.bat you'll see
set CLASSPATH=%JAVA_HOME%\lib\tools.jar
then in catalina.bat, it's used like so
%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS%
-Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%"
-Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%"
-Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION%
I don't see any other vars that are included, so I think you're stuck with editing setclasspath.bat and changing how CLASSPATH is built. For Tomcat 6.0.20, this change was on like 74 of setclasspath.bat
set CLASSPATH=C:\app_config\java_app;%JAVA_HOME%\lib\tools.jar
> grepl("^[^_]+_1",s)
[1] FALSE
> grepl("^[^_]+_2",s)
[1] TRUE
basically, look for everything at the beginning except _
, and then the _2
.
+1 to @Ananda_Mahto for suggesting grepl
instead of grep

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:
struct { 11
char a; 012345678901
short b; ------------
char c; axbbcxxxdddd
int d;
};
This structure will occupy 12 bytes of memory (x being pad bytes).
Python works similarly (see the struct documentation):
>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12
Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:
>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'
Beware of letting struct handle padding. In C, these structures:
struct A { struct B {
short a; int a;
char b; char b;
}; };
are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:
>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'
Swift 5:
1) If you use Date type:
let firstDate = Date()
let secondDate = Date()
print(firstDate > secondDate)
print(firstDate < secondDate)
print(firstDate == secondDate)
2) If you use String type:
let firstStringDate = "2019-05-22T09:56:00.1111111"
let secondStringDate = "2019-05-22T09:56:00.2222222"
print(firstStringDate > secondStringDate) // false
print(firstStringDate < secondStringDate) // true
print(firstStringDate == secondStringDate) // false
I'm not sure or the second option works at 100%. But how much would I not change the values of firstStringDate and secondStringDate the result was correct.
Since PostgreSQL 10
CREATE TABLE test_new (

An example of copy row from dataGridView and added a new row in The same dataGridView:
DataTable Dt = new DataTable();
Dt.Columns.Add("Column1");
Dt.Columns.Add("Column2");
DataRow dr = Dt.NewRow();
DataGridViewRow dgvR = (DataGridViewRow)dataGridView1.CurrentRow;
dr[0] = dgvR.Cells[0].Value;
dr[1] = dgvR.Cells[1].Value;
Dt.Rows.Add(dR);
dataGridView1.DataSource = Dt;
modern shells already support arrays( and even associative arrays). So please do use them, and use less of eval.
var1="this is the real value"
array=("$var1")
# or array[0]="$var1"
then when you want to call it , echo ${array[0]}
A 'fun' way to learn socket.io is to play BrowserQuest by mozilla and look at its source code :-)
Using the base
package:
df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))
# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]
# One line
df[df$name %in% c("Tom", "Lynn"), ]
Output:
days name
1 88 Lynn
2 11 Tom
6 1 Tom
7 222 Lynn
8 2 Lynn
Using sqldf
:
library(sqldf)
# Two alternatives:
sqldf('SELECT *
FROM df
WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
FROM df
WHERE name IN ("Tom", "Lynn")')
To add to @abevieiramota's excellent answer, you can get the euqivalent of tight_layout with constrained_layout. You will still get large horizontal gaps if you use imshow
instead of pcolormesh
because of the 1:1 aspect ratio imposed by imshow
.
import numpy as np
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=2, ncols=2, constrained_layout=True)
for ax in axes.flat:
im = ax.pcolormesh(np.random.random((10,10)), vmin=0, vmax=1)
fig.colorbar(im, ax=axes.flat)
plt.show()
For Mac OS X, using TextEdit or the natural environmental editor for text:

The XP Support Tools (which can be installed from your XP CD) come with a program called setx.exe
:
C:\Program Files\Support Tools>setx /?
SETX: This program is used to set values in the environment
of the machine or currently logged on user using one of three modes.
1) Command Line Mode: setx variable value [-m]
Optional Switches:
-m Set value in the Machine environment. Default is User.
...
For more information and example use: SETX -i
I think Windows 7 actually comes with setx
as part of a standard install.
read the documentation: matplotlib.pyplot.subplots
pyplot.subplots()
returns a tuple fig, ax
which is unpacked in two variables using the notation
fig, axes = plt.subplots(nrows=2, ncols=2)
the code
fig = plt.figure()
axes = fig.subplots(nrows=2, ncols=2)
does not work because subplots()
is a function in pyplot
not a member of the object Figure
.
All previous answers which I checked would list the files to be committed, too.
Here is a simple and easy solution that only lists files which are not yet in the
repo and not subject to .gitignore
.
git status --porcelain | awk '/^\?\?/ { print $2; }'
or
git status --porcelain | grep -v '\?\?'
Docs recommends to solve most of the needs for static functions with package-level functions. They are simply declared outside a class in a source code file. The package of a file can be specified at the beginning of a file with the package keyword.
Declaration
package foo
fun bar() = {}
Usage
import foo.bar
Alternatively
import foo.*
You can now call the function with:
bar()
or if you do not use the import keyword:
foo.bar()
If you do not specify the package the function will be accessible from the root.
If you only have experience with java, this might seem a little strange. The reason is that kotlin is not a strictly object-oriented language. You could say it supports methods outside of classes.
Edit: They have edited the documentation to no longer include the sentence about recommending package level functions. This is the original that was referred to above.
Drop in the image in /res/drawable folder. Then in Eclipse Menu, do ->Project -> Clean. This will do a clean build if set to build automatically.

I don't know if this will help anyone or not but as I was facing the same issue I thought of sharing how I got the solution.
You can use track by attribute in your ng-options
.
Assume that you have:
variants:[{'id':0, name:'set of 6 traits'}, {'id':1, name:'5 complete sets'}]
You can mention your ng-options
as:
ng-options="v.name for v in variants track by v.id"
Hope this helps someone in future.
If you are dealing with older versions of .NET Framework, then support for TLS 1.2 is available in our SecureBlackbox product in both client and server components. SecureBlackbox contains its own implementation of all algorithms, so it doesn't matter which version of .NET-based framework you use (including .NET CF) - you'll have TLS 1.2 with the latest additions in all cases.
Please note that SecureBlackbox wont magically add TLS 1.2 to framework classes - instead you need to use SecureBlackbox classes and components explicitly.
Building on an earlier answer, I am doing this in an Angular5 project.
Started with:
// el.scrollIntoView(true);
el.scrollIntoView({
behavior: 'smooth',
block: 'start'
});
window.scrollBy(0, -10);
But this gave some problems and needed to setTimeout for the scrollBy() like this:
//window.scrollBy(0,-10);
setTimeout(() => {
window.scrollBy(0,-10)
}, 500);
And it works perfectly in MSIE11 and Chrome 68+. I have not tested in FF. 500ms was the shortest delay I would venture. Going lower sometimes failed as the smooth scroll had not yet completed. Adjust as required for your own project.
+1 to Fred727 for this simple but effective solution.
IrishChieftain didn't really address the question, so here's my take:
eval() is supposed to be used for data that is not known at run time. Whether that be user input (dangerous) or other sources.
Use vim. ^-^ (gVim, to be precise)
You'll have it all (with some plugins).
Btw, snippetsEmu is a nice tool for coding with useful snippets (like in TextMate). You can use (or modify) a pre-made package or make your own.
this works with most types of elements:
$('selector').on('click',function(e){
log(e.currentTarget.id);
});
Well, if you're willing/ready to switch to Python 3 (which you may not be due to the backwards incompatibility with some Python 2 code), you don't have to do any converting; all text in Python 3 is represented with Unicode strings, which also means that there's no more usage of the u'<text>'
syntax. You also have what are, in effect, strings of bytes, which are used to represent data (which may be an encoded string).
http://docs.python.org/3.1/whatsnew/3.0.html#text-vs-data-instead-of-unicode-vs-8-bit
(Of course, if you're currently using Python 3, then the problem is likely something to do with how you're attempting to save the text to a file.)
From the HashSet<T>
page on MSDN:
The HashSet(Of T) class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order.

I have the same issue with windows10, apache 2.2.25, php 5.2 Im trying to add GD to a working PHP.
how I turn around and change between forward and backward slash, plus trailing or not, I get some variant of ;
PHP Warning: PHP Startup: Unable to load dynamic library 'C:/php\php_gd2.dll' - Det g\xe5r inte att hitta den angivna modulen.\r\n in Unknown on line 0
(swedish translated: 'It is not possible to find the module' )
in this perticular case, the php.ini was: extension_dir = "C:/php"
the dll is put in two places C:\php and C:\php\ext
IS it possible that there is and "error" in the error log entry ? I.e. that the .dll IS found (as a file) but not of the right format, or something like that ??

There are various methods available in Rust to concatenate strings
concat!()
):fn main() {
println!("{}", concat!("a", "b"))
}
The output of the above code is :
ab
push_str()
and +
operator):fn main() {
let mut _a = "a".to_string();
let _b = "b".to_string();
let _c = "c".to_string();
_a.push_str(&_b);
println!("{}", _a);
println!("{}", _a + &_c);
}
The output of the above code is:
ab
abc
Using format!()
):fn main() {
let mut _a = "a".to_string();
let _b = "b".to_string();
let _c = format!("{}{}", _a, _b);
println!("{}", _c);
}
The output of the above code is :

How about you store it like this? Maybe in username:password format, so
sebastion:password123
anotheruser:password321
Then you can use list($username,$password) = explode(':',file_get_contents('users.txt'));
to parse the data on your end.
The answer of Pardeep Jain can be useful for static data, but what if we have an array in JSON?
For example, we have i values and get the value of id field
alert(obj[i].id); //works!
But what if we need key with spaces?
In this case, the following construction can help (without point between [] blocks):
alert(obj[i]["No. of interfaces"]); //works too!
Compile the Release version as .exe file, then just copy onto a machine with a suitable version of .NET Framework installed and run it there. The .exe file is located in the bin\Release subfolder of the project folder.
Off hand, setting the http.agent
system property to ""
might do the trick (I don't have the code in front of me).
You might get away with:
System.setProperty("http.agent", "");
but that might require a race between you and initialisation of the URL protocol handler, if it caches the value at startup (actually, I don't think it does).
The property can also be set through JNLP files (available to applets from 6u10) and on the command line:
-Dhttp.agent=
Or for wrapper commands:
-J-Dhttp.agent=
You can do that using the descendant selectors:
$("#a #b")
However, id values are supposed to be unique on a page.
Yes you can pass variable no. of arguments to a function. You can use apply
to achieve this.
E.g.:
var arr = ["Hi","How","are","you"];
function applyTest(){
var arg = arguments.length;
console.log(arg);
}
applyTest.apply(null,arr);
gdb disassemble has a /m to include source code alongside the instructions. This is equivalent of objdump -S, with the extra benefit of confining to just the one function (or address-range) of interest.
function fetch_comments($ticket_id){
$this->db->select('tbl_tickets_replies.comments,
tbl_users.username,tbl_roles.role_name');
$this->db->where('tbl_tickets_replies.ticket_id',$ticket_id);
$this->db->join('tbl_users','tbl_users.id = tbl_tickets_replies.user_id');
$this->db->join('tbl_roles','tbl_roles.role_id=tbl_tickets_replies.role_id');
return $this->db->get('tbl_tickets_replies');
}
Multiple functions, but this will give you what you need (tested on SQL Server 2008)
Edit: The following works not only for a time
type, but for a datetime
as well.

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.
location / {
proxy_pass http://example.com;
proxy_set_header Host example.com;
proxy_set_header HTTP_Country-Code $geoip_country_code;
proxy_pass_request_headers on;
}
And now it's passed to the proxy backend.
You can do this:

Yup, BOOL is a typedef for a signed char according to objc.h.
I don't know about bool, though. That's a C++ thing, right? If it's defined as a signed char where 1 is YES/true and 0 is NO/false, then I imagine it doesn't matter which one you use.
Since BOOL is part of Objective-C, though, it probably makes more sense to use a BOOL for clarity (other Objective-C developers might be puzzled if they see a bool in use).

Since dob
is DATE
data type, you need to convert the literal to DATE
using TO_DATE
and the proper format model. The syntax is:
TO_DATE('<date_literal>', '<format_model>')
For example,
SQL> CREATE TABLE t(dob DATE);
Table created.
SQL> INSERT INTO t(dob) VALUES(TO_DATE('17/12/2015', 'DD/MM/YYYY'));
1 row created.
SQL> COMMIT;
Commit complete.
SQL> SELECT * FROM t;
DOB
----------
17/12/2015
A DATE
data type contains both date and time elements. If you are not concerned about the time portion, then you could also use the ANSI Date literal which uses a fixed format 'YYYY-MM-DD'
and is NLS independent.
For example,
SQL> INSERT INTO t(dob) VALUES(DATE '2015-12-17');
1 row created.

In a discussion, Simon clearly mentioned that:
While the datatype used for storing the list of handles may be ordered by insertion, the order in which the WebDriver implementation iterates over the window handles to insert them has no requirement to be stable. The ordering is arbitrary.
Using Selenium v3.x opening a website in a New Tab through Python is much easier now. We have to induce an WebDriverWait for number_of_windows_to_be(2)
and then collect the window handles every time we open a new tab/window and finally iterate through the window handles and switchTo().window(newly_opened)
as required. Here is a solution where you can open http://www.google.co.in
in the initial TAB and https://www.yahoo.com
in the adjacent TAB:
Code Block:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait

git stash apply
Just check out the branch you want your changes on, and then git stash apply
. Then use git diff
to see the result.
After you're all done with your changes—the apply
looks good and you're sure you don't need the stash any more—then use git stash drop
to get rid of it.
I always suggest using git stash apply
rather than git stash pop
. The difference is that apply
leaves the stash around for easy re-try of the apply
, or for looking at, etc. If pop
is able to extract the stash, it will immediately also drop
it, and if you the suddenly realize that you wanted to extract it somewhere else (in a different branch), or with --index
, or some such, that's not so easy. If you apply
, you get to choose when to drop
.
It's all pretty minor one way or the other though, and for a newbie to git, it should be about the same. (And you can skip all the rest of this!)
There are at least three or four different "ways to use git stash", as it were. The above is for "way 1", the "easy way":
You started with a clean branch, were working on some changes, and then realized you were doing them in the wrong branch. You just want to take the changes you have now and "move" them to another branch.
This is the easy case, described above. Run git stash save
(or plain git stash
, same thing). Check out the other branch and use git stash apply
. This gets git to merge in your earlier changes, using git's rather powerful merge mechanism. Inspect the results carefully (with git diff
) to see if you like them, and if you do, use git stash drop
to drop the stash. You're done!
You started some changes and stashed them. Then you switched to another branch and started more changes, forgetting that you had the stashed ones.
Now you want to keep, or even move, these changes, and apply your stash too.
You can in fact git stash save
again, as git stash
makes a "stack" of changes. If you do that you have two stashes, one just called stash
—but you can also write stash@{0}
—and one spelled stash@{1}
. Use git stash list
(at any time) to see them all. The newest is always the lowest-numbered. When you git stash drop
, it drops the newest, and the one that was stash@{1}
moves to the top of the stack. If you had even more, the one that was stash@{2}
becomes stash@{1}
, and so on.
You can apply
and then drop
a specific stash, too: git stash apply stash@{2}
, and so on. Dropping a specific stash, renumbers only the higher-numbered ones. Again, the one without a number is also stash@{0}
.
If you pile up a lot of stashes, it can get fairly messy (was the stash I wanted stash@{7}
or was it stash@{4}
? Wait, I just pushed another, now they're 8 and 5?). I personally prefer to transfer these changes to a new branch, because branches have names, and cleanup-attempt-in-December
means a lot more to me than stash@{12}
. (The git stash
command takes an optional save-message, and those can help, but somehow, all my stashes just wind up named WIP on branch
.)
(Extra-advanced) You've used git stash save -p
, or carefully git add
-ed and/or git rm
-ed specific bits of your code before running git stash save
. You had one version in the stashed index/staging area, and another (different) version in the working tree. You want to preserve all this. So now you use git stash apply --index
, and that sometimes fails with:
Conflicts in index. Try without --index.
You're using git stash save --keep-index
in order to test "what will be committed". This one is beyond the scope of this answer; see this other StackOverflow answer instead.
For complicated cases, I recommend starting in a "clean" working directory first, by committing any changes you have now (on a new branch if you like). That way the "somewhere" that you are applying them, has nothing else in it, and you'll just be trying the stashed changes:
git status # see if there's anything you need to commit
# uh oh, there is - let's put it on a new temp branch
git checkout -b temp # create new temp branch to save stuff
git add ... # add (and/or remove) stuff as needed
git commit # save first set of changes
Now you're on a "clean" starting point. Or maybe it goes more like this:
git status # see if there's anything you need to commit
# status says "nothing to commit"
git checkout -b temp # optional: create new branch for "apply"
git stash apply # apply stashed changes; see below about --index
The main thing to remember is that the "stash" is a commit, it's just a slightly "funny/weird" commit that's not "on a branch". The apply
operation looks at what the commit changed, and tries to repeat it wherever you are now. The stash will still be there (apply
keeps it around), so you can look at it more, or decide this was the wrong place to apply
it and try again differently, or whatever.
Any time you have a stash, you can use git stash show -p
to see a simplified version of what's in the stash. (This simplified version looks only at the "final work tree" changes, not the saved index changes that --index
restores separately.) The command git stash apply
, without --index
, just tries to make those same changes in your work-directory now.
This is true even if you already have some changes. The apply
command is happy to apply a stash to a modified working directory (or at least, to try to apply it). You can, for instance, do this:
git stash apply stash # apply top of stash stack
git stash apply stash@{1} # and mix in next stash stack entry too
You can choose the "apply" order here, picking out particular stashes to apply in a particular sequence. Note, however, that each time you're basically doing a "git merge", and as the merge documentation warns:
Running git merge with non-trivial uncommitted changes is discouraged: while possible, it may leave you in a state that is hard to back out of in the case of a conflict.
If you start with a clean directory and are just doing several git apply
operations, it's easy to back out: use git reset --hard
to get back to the clean state, and change your apply
operations. (That's why I recommend starting in a clean working directory first, for these complicated cases.)
Let's say you're doing Lots Of Advanced Git Stuff, and you've made a stash, and want to git stash apply --index
, but it's no longer possible to apply the saved stash with --index
, because the branch has diverged too much since the time you saved it.
This is what git stash branch
is for.
If you:
stash
, thengit stash apply --index
the attempt to re-create the changes definitely will work. This is what git stash branch newbranch
does. (And it then drops the stash since it was successfully applied.)
--index
(what the heck is it?)What the --index
does is simple to explain, but a bit complicated internally:
git add
(or "stage") them before commit
ing.git stash
, you might have edited both files foo
and zorg
, but only staged one of those.git add
s the add
ed things and does not git add
the non-added things. That is, if you add
ed foo
but not zorg
back before you did the stash
, it might be nice to have that exact same setup. What was staged, should again be staged; what was modified but not staged, should again be modified but not staged.The --index
flag to apply
tries to set things up this way. If your work-tree is clean, this usually just works. If your work-tree already has stuff add
ed, though, you can see how there might be some problems here. If you leave out --index
, the apply
operation does not attempt to preserve the whole staged/unstaged setup. Instead, it just invokes git's merge machinery, using the work-tree commit in the "stash bag". If you don't care about preserving staged/unstaged, leaving out --index
makes it a lot easier for git stash apply
to do its thing.
Download the code from github into the node_modules directory
var moduleName = require("<name of directory>")
that should do it.
if the module has dependancies and has a package.json, open the module and enter npm install.
Hope this helps
var a = 10;
myFunction();
function myFunction(){
a = 20;
}
alert("Value of 'a' outside the function " + a); //outputs 20
You can find details here To Quickly Format XML using Pretty Print (libXML)
Installing the XML Tools
If you run Notepad++ and look in the Plugins menu, you’ll see that the XML Tools aren’t there:
Download the XML tools from here.
Unzip the file and copy the XMLTools.dll to the Notepad++ plugins folder (in the example above: C:\Program Files (x86)\Notepad++\plugins):
Re-start Notepad++ and you should now see the XMLTools appear in the Plugins menu.
Unzip the ext_libs.zip file and then copy the unzipped DLLs to the Notepad++ installation directory (in the example above: C:\Program Files (x86)\Notepad++).
Re-start Notepad++ and you should finally see the proper XML Tools menu.
The feature I use the most is “Pretty print (XML only – with line breaks)”. This will format any piece of XML with all the proper line spacing.

Also, when you uninstall the package, the first item listed is the directory to the executable.
Just that i want to show how to do what do said @JafarKhQ in Kotlin for those who use kotlin that might help them and save theme time too:
so you have to create a companion objet to create new newInstance function
you can set the paremter of the function whatever you want. using
val args = Bundle()
you can set your args.
You can now use args.putSomthing
to add you args which u give as a prameter in your newInstance function.
putString(key:String,str:String)
to add string for example and so on
Now to get the argument you can use
arguments.getSomthing(Key:String)
=> like arguments.getString("1")
here is a full example
class IntervModifFragment : DialogFragment(), ModContract.View
{
companion object {
fun newInstance( plom:String,type:String,position: Int):IntervModifFragment {
val fragment =IntervModifFragment()
val args = Bundle()
args.putString( "1",plom)
args.putString("2",type)
args.putInt("3",position)
fragment.arguments = args
return fragment
}
}
...
override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
fillSpinerPlom(view,arguments.getString("1"))
fillSpinerType(view, arguments.getString("2"))
confirmer_virme.setOnClickListener({on_confirmClick( arguments.getInt("3"))})
val dateSetListener = object : DatePickerDialog.OnDateSetListener {
override fun onDateSet(view: DatePicker, year: Int, monthOfYear: Int,
dayOfMonth: Int) {
val datep= DateT(year,monthOfYear,dayOfMonth)
updateDateInView(datep.date)
}
}
}
...
}
Now how to create your dialog you can do somthing like this in another class
val dialog = IntervModifFragment.newInstance(ListInter.list[position].plom,ListInter.list[position].type,position)
like this for example
class InterListAdapter(private val context: Context, linkedList: LinkedList<InterItem> ) : RecyclerView.Adapter<InterListAdapter.ViewHolder>()
{
...
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
...
holder.btn_update!!.setOnClickListener {
val dialog = IntervModifFragment.newInstance(ListInter.list[position].plom,ListInter.list[position].type,position)
val ft = (context as AppCompatActivity).supportFragmentManager.beginTransaction()
dialog.show(ft, ContentValues.TAG)
}
...
}
..
}
For C, at least, per C11 6.7.5:
A declaration specifies the interpretation and attributes of a set of identifiers. A definition of an identifier is a declaration for that identifier that:
for an object, causes storage to be reserved for that object;
for a function, includes the function body;
for an enumeration constant, is the (only) declaration of the identifier;
for a typedef name, is the first (or only) declaration of the identifier.
Per C11 6.7.9.8-10:
An initializer specifies the initial value stored in an object ... if an object that has automatic storage is not initialized explicitly, its value is indeterminate.
So, broadly speaking, a declaration introduces an identifier and provides information about it. For a variable, a definition is a declaration which allocates storage for that variable.
Initialization is the specification of the initial value to be stored in an object, which is not necessarily the same as the first time you explicitly assign a value to it. A variable has a value when you define it, whether or not you explicitly give it a value. If you don't explicitly give it a value, and the variable has automatic storage, it will have an initial value, but that value will be indeterminate. If it has static storage, it will be initialized implicitly depending on the type (e.g. pointer types get initialized to null pointers, arithmetic types get initialized to zero, and so on).
So, if you define an automatic variable without specifying an initial value for it, such as:
int myfunc(void) {
int myvar;
...
You are defining it (and therefore also declaring it, since definitions are declarations), but not initializing it. Therefore, definition does not equal declaration plus initialization.
Use jQuery's noConflict
. It did wonders for me
var example=jQuery.noConflict();
example(function(){
example('div#rift_connect').click(function(){
example('span#resultado').text("Hello, dude!");
});
});
That is, assuming you included jQuery on your HTML
<script language="javascript" type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
Execute the following command to check whether a web site is up, and what status message the web server is showing:
curl -Is http://www.google.com | head -1 HTTP/1.1 200 OK
Status code ‘200 OK’ means that the request has succeeded and a website is reachable.
Try this:
...(to_date('2011/04/22 08:30:00', 'yyyy/mm/dd hh24:mi:ss'));
Can you do the string conversion while the List(of object) is being built? This would be the only way to avoid enumerating the whole list after the List(of object) was created.
foreach (DataTable table in dataSet.Tables)
{
foreach (DataRow row in table.Rows)
{
foreach (object item in row.ItemArray)
{
// read item
}
}
}
Or, if you need the column info:
foreach (DataTable table in dataSet.Tables)
{
foreach (DataRow row in table.Rows)
{
foreach (DataColumn column in table.Columns)
{
object item = row[column];
// read column and item
}
}
}
var iframe = document.getElementById('iframe');
$(iframe).contents().find("html").html();
Create a sub-class User with an id field and screen_name field, like this:
public class User
{
public string id { get; set; }
public string screen_name { get; set; }
}
public class Response {
public string id { get; set; }
public string text { get; set; }
public string url { get; set; }
public string width { get; set; }
public string height { get; set; }
public string size { get; set; }
public string type { get; set; }
public string timestamp { get; set; }
public User user { get; set; }
}
Why does it need to be done with any JavaScript at all?
<form>
<!-- snip -->
<input type="reset" value="Reset"/>
</form>
http://www.w3.org/TR/html5/the-input-element.html#attr-input-type-keywords
Tried that one first, it won't clear fields with default values.
Here's a way to do it with jQuery, then:
$('.reset').on('click', function() {
$(this).closest('form').find('input[type=text], textarea').val('');
});
As far as this being a "bug" with relation to the spec; it isn't. As the author of the post questions, the behaviour for this would be "undefined" since this behaviour in IE only happens on form controls, as per spec:
CSS 2.1 does not define which properties apply to form controls and frames, or how CSS can be used to style them. User agents may apply CSS properties to these elements. Authors are recommended to treat such support as experimental.

I ran into the same problem. I had a PNG file in a Java package and it wasn't exported in the final JAR along with the sources, which caused the app to crash upon start (file not found).
None of the answers above solved my problem but I found the solution on the Gradle forums. I added the following to my build.gradle
file :
sourceSets.main.resources.srcDirs = [ "src/" ]
sourceSets.main.resources.includes = [ "**/*.png" ]
It tells Gradle to look for resources in the src
folder, and ask it to include only PNG files.
EDIT: Beware that if you're using Eclipse, this will break your run configurations and you'll get a main class not found
error when trying to run your program. To fix that, the only solution I've found is to move the image(s) to another directory, res/
for example, and to set it as srcDirs
instead of src/
.
git checkout
has the --ours
option to check out the version of the file that you had locally (as opposed to --theirs
, which is the version that you pulled in). You can pass .
to git checkout
to tell it to check out everything in the tree. Then you need to mark the conflicts as resolved, which you can do with git add
, and commit your work once done:
git checkout --ours . # checkout our local version of all files
git add -u # mark all conflicted files as merged
git commit # commit the merge
Note the .
in the git checkout
command. That's very important, and easy to miss. git checkout
has two modes; one in which it switches branches, and one in which it checks files out of the index into the working copy (sometimes pulling them into the index from another revision first). The way it distinguishes is by whether you've passed a filename in; if you haven't passed in a filename, it tries switching branches (though if you don't pass in a branch either, it will just try checking out the current branch again), but it refuses to do so if there are modified files that that would effect. So, if you want a behavior that will overwrite existing files, you need to pass in .
or a filename in order to get the second behavior from git checkout
.
It's also a good habit to have, when passing in a filename, to offset it with --
, such as git checkout --ours -- <filename>
. If you don't do this, and the filename happens to match the name of a branch or tag, Git will think that you want to check that revision out, instead of checking that filename out, and so use the first form of the checkout
command.
I'll expand a bit on how conflicts and merging work in Git. When you merge in someone else's code (which also happens during a pull; a pull is essentially a fetch followed by a merge), there are few possible situations.
The simplest is that you're on the same revision. In this case, you're "already up to date", and nothing happens.
Another possibility is that their revision is simply a descendent of yours, in which case you will by default have a "fast-forward merge", in which your HEAD
is just updated to their commit, with no merging happening (this can be disabled if you really want to record a merge, using --no-ff
).
Then you get into the situations in which you actually need to merge two revisions. In this case, there are two possible outcomes. One is that the merge happens cleanly; all of the changes are in different files, or are in the same files but far enough apart that both sets of changes can be applied without problems. By default, when a clean merge happens, it is automatically committed, though you can disable this with --no-commit
if you need to edit it beforehand (for instance, if you rename function foo
to bar
, and someone else adds new code that calls foo
, it will merge cleanly, but produce a broken tree, so you may want to clean that up as part of the merge commit in order to avoid having any broken commits).
The final possibility is that there's a real merge, and there are conflicts. In this case, Git will do as much of the merge as it can, and produce files with conflict markers (<<<<<<<
, =======
, and >>>>>>>
) in your working copy. In the index (also known as the "staging area"; the place where files are stored by git add
before committing them), you will have 3 versions of each file with conflicts; there is the original version of the file from the ancestor of the two branches you are merging, the version from HEAD
(your side of the merge), and the version from the remote branch.
In order to resolve the conflict, you can either edit the file that is in your working copy, removing the conflict markers and fixing the code up so that it works. Or, you can check out the version from one or the other sides of the merge, using git checkout --ours
or git checkout --theirs
. Once you have put the file into the state you want it, you indicate that you are done merging the file and it is ready to commit using git add
, and then you can commit the merge with git commit
.
This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)
There have been a slew of recent changes in this arena, so I thought a fresh answer would be helpful.

I know this is a really old question.. and it appears it was answered.. But I got here with the same question but a different reason for the question, and so a slightly different answer worked for me. I have a nice reusable generic datagridview that takes the datasource supplied to it and just displays the columns in their default order. I put aliases and column order and selection at the dataset's tableadapter level in designer. However changing the select query order of columns doesn't seem to impact the columns returned through the dataset. I have found the only way to do this in the designer, is to remove all the columns selected within the tableadapter, adding them back in the order you want them selected.
In my personal experience, it's difficult to enable shared folders in VirtualBox but it Is posible. I have a debian Buster guest virtual machine installed in my Windows 10 host.
I don't recognize exactly what did it, but I remember I went to Windows defender, my antivirus to see if they recognize VirtualBox as a program and not as a virus. After that, I press right click on the document file and allowed to share the folder and I gave click to some buttons there and accepted to share with groups and with muy user in Windows 10.
Also, I found a webpage of Windows about something like virtual machines that I don't remember well, but it took me to a panel and I had to change three things double clicking so when I update Windows, it recognizes my virtual machine. Also, in muy debian, in the terminal, using some command lines, muy VirtualBox recognized my user giving permissions, I based on some info in the Ubuntu forums. I put all what I remember.
Close the IDE and open it again. This works if you did not use any code coverage tools and have just clicked the basic "Coverage" icon in the IDE.
if you have the BluetoothDevice object you can create bond(pair) from api 19 onwards with bluetoothDevice.createBond()
method.
Edit
for callback, if the request was accepted or denied you will have to create a BroadcastReceiver with BluetoothDevice.ACTION_BOND_STATE_CHANGED

The problem was that my array was in type u3 i changed it to float and it worked for me . I had a dataframe with Image column having the image/pic data.Reshaping part depends to person to person and image they deal with mine had 9126 size hence it was 96*96.
a = np.array(df_train.iloc[0].Image.split(),dtype='float')
a = a.reshape(96,96)

For case sensitive renaming, git mv somefolder someFolder
has worked for me before but didn't today for some reason. So as a workaround I created a new folder temp
, moved all the contents of somefolder
into temp
, deleted somefolder
, committed the temp
, then created someFolder
, moved all the contents of temp
into someFolder
, deleted temp
, committed and pushed someFolder
and it worked! Shows up as someFolder

throw
will terminate the further execution & expose message string on catch the error.
try {
throw "I'm Evil"
console.log("You'll never reach to me", 123465)
} catch (e) {
console.log(e); // I'm Evil
}
_x000D_
Console after throw will never be reached cause of termination.
throw new Error
exposes an error event with two params name & message. It also terminate further execution
try {
throw new Error("I'm Evil")
console.log("You'll never reach to me", 123465)
} catch (e) {
console.log(e.name, e.message); // Error I'm Evil
}
_x000D_
And just for completeness, this works also, though is not technically the correct way to do it -
try {
throw Error("I'm Evil")
console.log("You'll never reach to me", 123465)
} catch (e) {
console.log(e.name, e.message); // Error I'm Evil
}
console.log(typeof(new Error("hello"))) // object
console.log(typeof(Error)) // function
_x000D_

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:
cursor.execute('INSERT INTO images VALUES(?)', (img,))
Without the comma, (img)
is just a grouped expression, not a tuple, and thus the img
string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.
>>> len(img)
74
>>> len((img,))
1
If you find it easier to read, you can also use a list literal:
cursor.execute('INSERT INTO images VALUES(?)', [img])
You are missing 'json' dataType in the $.post()

The git blame
command annotates lines with information from the revision which last modified the line, and... with Git 2.22 (Q2 2019), will do so faster, because of a performance fix around "git blame

blame.c
: don't drop origin blobs as eagerlyWhen a parent blob already has chunks queued up for blaming, dropping the blob at the end of one blame step will cause it to get reloaded right away, doubling the amount of I/O and unpacking when processing a linear history.
Keeping such parent blobs in memory seems like a reasonable optimization that should incur additional memory pressure mostly when processing the merges from old branches.
If the two hex strings are the same length and you want a hex string output then you might try this.
def hexxor(a, b): # xor two hex strings of the same length return "".join(["%x" % (int(x,16) ^ int(y,16)) for (x, y) in zip(a, b)])
There is also th:classappend
.
<a href="" class="baseclass" th:classappend="${isAdmin} ? adminclass : userclass"></a>
If isAdmin
is true
, then this will result in:
<a href="" class="baseclass adminclass"></a>
You're looking for an ellipsoid formula.
The best place I've found to start coding is based on the Geo::Ellipsoid library from CPAN. It gives you a baseline to create your tests off of and to compare your results with its results. I used it as the basis for a similar library for PHP at my previous employer.
Take a look at the location
method. Call it twice and you've got your bbox.
You didn't post what language you were using. There may already be a geocoding library available for you.
Oh, and if you haven't figured it out by now, Google maps uses the WGS84 ellipsoid.
/* Adding the script tag to the head as suggested before */
var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "http://code.jquery.com/jquery-2.2.1.min.js";
// Then bind the event to the callback function.
// There are several events for cross browser compatibility.
script.onreadystatechange = handler;
script.onload = handler;
// Fire the loading
head.appendChild(script);
function handler(){
console.log('jquery added :)');

I unplugged my cable and saw this. After it reached the end I was able to run it no problems.
You don't have to unplug to see this; just hit cancel and you will see its progress.
You may need read this https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape
and below there is a Note.
Note Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.
I write below code to remove the blank value in the array string.
string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();
Date d1 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
getParameter(date1));
Date d2 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
getParameter(date2));
long diff = d2.getTime() - d1.getTime();
System.out.println("Difference between " + d1 + " and "+ d2+" is "
+ (diff / (1000 * 60 * 60 * 24)) + " days.");
From the man git-stash
page:
The modifications stashed away by this command can be listed with git stash list, inspected with git stash show
show [<stash>]
Show the changes recorded in the stash as a diff between the stashed state and
its original parent. When no <stash> is given, shows the latest one. By default,
the command shows the diffstat, but it will accept any format known to git diff
(e.g., git stash show -p stash@{1} to view the second most recent stash in patch
form).
To list the stashed modifications
git stash list
To show files changed in the last stash
git stash show
So, to view the content of the most recent stash, run
git stash show -p
To view the content of an arbitrary stash, run something like
git stash show -p stash@{1}
You have a string representing a JSON serialized JavaScript object. You need to deserialize it back to a JavaScript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.
var resultJSON = '{"FirstName":"John","LastName":"Doe","Email":"[email protected]","Phone":"123 dead drive"}';
var result = $.parseJSON(resultJSON);
$.each(result, function(k, v) {
//display the key and value pair
alert(k + ' is ' + v);
});
Ctrl + A and then Ctrl+D. Doing this will detach you from the screen
session which you can later resume by doing screen -r
.
You can also do: Ctrl+A then type :. This will put you in screen command mode. Type the command detach
to be detached from the running screen session.
There are two problems with your original solution. Firstly, your example text:
<option value value='1' >A
has two occurences of the "value" word. Your regex does not. Also, you need to escape the opening brace in the quantifier of your regex or Vim will interpret it as a literal brace. This regex works:
:%s/<option value value='.\{1,}' >//g

I was able to log on to the mysql server after running the command @robregonm suggested:
mysql_upgrade -u root -p --force
A MySQL server restart is required.
Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html
plt.subplots
is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:
import numpy as np
import matplotlib.pyplot as plt
x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)
fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()
I was looking for something and I found this post. I post this code that managed many-to-many relationships in case someone needs it.
var UserInRole = db.UsersInRoles.Include(u => u.UserProfile).Include(u => u.Roles)
.Select (m => new
{
UserName = u.UserProfile.UserName,
RoleName = u.Roles.RoleName
});
You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.
SELECT * FROM <table_name> WHERE id = 1
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';
If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':
hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')
jQuery provides you with:
$(".news").hide();
$(".news").show();
You can then easily show and hide the element(s).

Summarize disk space used for each FILE and/or directory.
Disk space is printed in units of 1024 bytes.
Options:
-a Show sizes of files in addition to directories
-H Follow symbolic links that are FILE command line args
-L Follow all symbolic links encountered
-d N Limit output to directories (and files with -a) of depth < N
-c Output a grand total
-l Count sizes many times if hard linked
-s Display only a total for each argument
-x Skip directories on different filesystems
-h Print sizes in human readable format (e.g., 1K 243M 2G )
-m Print sizes in megabytes
-k Print sizes in kilobytes(default)
I did not know that even with the "Allow Installation of non-Marked application", I still needed to sign the application.
I self-signed my application, following this link self-sign and release application, It only took 5 minutes, then I emailed the signed-APK file to myself and downloaded it to SD-card and then installed it without any problem.

InnoDB works slightly different that MyISAM and they both are viable options. You should use what you think it fits the project.
Some keypoints will be:
Notes:
Notes2: - I am reading this book "High performance MySQL", the author says "InnoDB loads data and creates indexes slower than MyISAM", this could also be a very important factor when deciding what to use.
UPDATE : 2020
Instead of using Redirect, Simply add multiple route in the path
Example:
<Route exact path={["/","/defaultPath"]} component={searchDashboard} />
Use for on refresh event
window.onbeforeunload = function(e) {
return 'Dialog text here.';
};
And
$(window).unload(function() {
alert('Handler for .unload() called.');
});
Running ionic info
on your project directory give all the info you need the npm version, cli, app script and some more
I made the following filter:
angular.module('app').filter('ifEmpty', function() {
return function(input, defaultValue) {
if (angular.isUndefined(input) || input === null || input === '') {
return defaultValue;
}
return input;
}
});
To be used like this:
<span>{{aPrice | currency | ifEmpty:'N/A'}}</span>
<span>{{aNum | number:3 | ifEmpty:0}}</span>

You can't. If you want to change it, you need to use a list instead of a tuple.
Note that you could instead make a new tuple that has the new value as its first element.

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln
).
At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename
) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*
. Updated above code to reflect this.
Also as pointed out in the comments (by Charles Brandt), /filename
must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.
Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts
As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.
According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering
", in which case you have to pass sequence and runlevel configuration through command line arguments.
The equivalent argument set for the above example is
sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

To delete a cookie I set it again with an empty value and expiring in 1 second. In details, I always use one of the following flavours (I tend to prefer the second one):
1.
function setCookie(key, value, expireDays, expireHours, expireMinutes, expireSeconds) {
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = key +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie(name, "", null , null , null, 1);
}
Usage:
setCookie("reminder", "buyCoffee", null, null, 20);
deleteCookie("reminder");
2
function setCookie(params) {
var name = params.name,
value = params.value,
expireDays = params.days,
expireHours = params.hours,
expireMinutes = params.minutes,
expireSeconds = params.seconds;
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = name +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie({name: name, value: "", seconds: 1});
}
Usage:
setCookie({name: "reminder", value: "buyCoffee", minutes: 20});
deleteCookie("reminder");
