The main thing is that if you don't store in onSaveInstanceState()
then onRestoreInstanceState()
will not be called. This is the main difference between restoreInstanceState()
and onCreate()
. Make sure you really store something. Most likely this is your problem.
Yes, tasks waiting for IO are blocked, and other tasks get executed. Selecting the next task is done by the Linux scheduler.
It bewilders me that we encourage one-off custom methods whenever a perfectly good, well used library like Apache Commons has solved the problem already. Though the solution is trivial if not absurd, it is irresponsible to encourage such a behavior due to long term maintenance and accessibility.
Just go with Apache Commons
While working with MVC and having lots of if
statements where i only care about either true
or false
, and printing null
, or string.Empty
in the other case, I came up with:
public static TResult WhenTrue<TResult>(this Boolean value, Func<TResult> expression)
{
return value ? expression() : default(TResult);
}
public static TResult WhenTrue<TResult>(this Boolean value, TResult content)
{
return value ? content : default(TResult);
}
public static TResult WhenFalse<TResult>(this Boolean value, Func<TResult> expression)
{
return !value ? expression() : default(TResult);
}
public static TResult WhenFalse<TResult>(this Boolean value, TResult content)
{
return !value ? content : default(TResult);
}
It allows me to change <%= (someBool) ? "print y" : string.Empty %>
into <%= someBool.WhenTrue("print y") %>
.
I only use it in my Views where I mix code and HTML, in code files writing the "longer" version is more clear IMHO.
CREATE OR REPLACE FUNCTION HASTANE.getXXXXX(p_rowid in rowid) return VARCHAR2
as
l_data long;
begin
select XXXXXX into l_data from XXXXX where rowid = p_rowid;
return substr( l_data, 1, 4000);
end getlabrapor1;
Much shorter:
search
scans through the whole string.
match
scans only the beginning of the string.
Following Ex says it:
>>> a = "123abc"
>>> re.match("[a-z]+",a)
None
>>> re.search("[a-z]+",a)
abc
There are two approaches that I know of. The first is to tell the browser not to cache the page. Setting the Response to no cache takes care of that, however as you suspect the browser will often ignore this directive. The other approach is to set the date time of your response to a point in the future. I believe all browsers will correct this to the current time when they add the page to the cache, but it will show the page as newer when the comparison is made. I believe there may be some cases where a comparison is not made. I am not sure of the details and they change with each new browser release. Final note I have had better luck with pages that "refresh" themselves (another response directive). The refresh seems less likely to come from the cache.
Hope that helps.

unittest comes with the standard library, but I would recomend you nosetests.
"nose extends unittest to make testing easier."
I would also recomend you pylint
"analyzes Python source code looking for bugs and signs of poor quality."
I have not found suitable answer, so here goes my take, which builds upon @toszter answer, but does not use system Python (and you may know, it is not always good idea to install setuptools and virtualenv at system level when dealing with many Python configurations):
#!/bin/sh
mkdir python_ve
cd python_ve
MYROOT=`pwd`
mkdir env pyenv dep
cd ${MYROOT}/dep
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-15.2.tar.gz#md5=a9028a9794fc7ae02320d32e2d7e12ee
wget https://raw.github.com/pypa/virtualenv/master/virtualenv.py
wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
xz -d Python-2.7.9.tar.xz
cd ${MYROOT}/pyenv
tar xf ../dep/Python-2.7.9.tar
cd Python-2.7.9
./configure --prefix=${MYROOT}/pyenv && make -j 4 && make install
cd ${MYROOT}/pyenv
tar xzf ../dep/setuptools-15.2.tar.gz
cd ${MYROOT}
pyenv/bin/python dep/virtualenv.py --no-setuptools --python=${MYROOT}/pyenv/bin/python --verbose env
env/bin/python pyenv/setuptools-15.2/setup.py install
env/bin/easy_install pip
echo "virtualenv in ${MYROOT}/env"
The trick of breaking chicken-egg problem here is to make virtualenv without setuptools first, because it otherwise fails (pip can not be found). It may be possible to install pip / wheel directly, but somehow easy_install was the first thing which came to my mind. Also, the script can be improved by factoring out concrete versions.
NB. Using xz in the script.
In C, there's no (real, distinct type of) strings. Every C "string" is an array of chars, zero terminated.
Therefore, to extract a character c at index i from string your_string, just use
char c = your_string[i];
Index is base 0 (first character is your_string[0], second is your_string[1]...).
For an ArrayAdapter
, notifyDataSetChanged
only works if you use the add()
, insert()
, remove()
, and clear()
on the Adapter.
When an ArrayAdapter
is constructed, it holds the reference for the List
that was passed in. If you were to pass in a List
that was a member of an Activity, and change that Activity member later, the ArrayAdapter
is still holding a reference to the original List
. The Adapter does not know you changed the List
in the Activity.
Your choices are:
ArrayAdapter
to modify the underlying List (add()
, insert()
, remove()
, clear()
, etc.)ArrayAdapter
with the new List
data. (Uses a lot of resources and garbage collection.)BaseAdapter
and ListAdapter
that allows changing of the underlying List
data structure.notifyDataSetChanged()
every time the list is updated. To call it on the UI-Thread, use the runOnUiThread()
of Activity
.
Then, notifyDataSetChanged()
will work.If you are using webjars. You need to add this in your configure
method:
http.authorizeRequests().antMatchers("/webjars/**").permitAll();
Make sure this is the first statement. For example:
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/webjars/**").permitAll();
http.authorizeRequests().anyRequest().authenticated();
http.formLogin()
.loginPage("/login")
.failureUrl("/login?error")
.usernameParameter("email")
.permitAll()
.and()
.logout()
.logoutUrl("/logout")
.deleteCookies("remember-me")
.logoutSuccessUrl("/")
.permitAll()
.and()
.rememberMe();
}
You will also need to have this in order to have webjars enabled:
@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
...
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
...
}
git rm --cached file
will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file
will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.
To use a pipe with the subprocess
module, you have to pass shell=True
.
However, this isn't really advisable for various reasons, not least of which is security. Instead, create the ps
and grep
processes separately, and pipe the output from one into the other, like so:
ps = subprocess.Popen(('ps', '-A'), stdout=subprocess.PIPE)
output = subprocess.check_output(('grep', 'process_name'), stdin=ps.stdout)
ps.wait()
In your particular case, however, the simple solution is to call subprocess.check_output(('ps', '-A'))
and then str.find
on the output.
For files encoding...
public class FRomUtf8ToIso {
static File input = new File("C:/Users/admin/Desktop/pippo.txt");
static File output = new File("C:/Users/admin/Desktop/ciccio.txt");
public static void main(String[] args) throws IOException {
BufferedReader br = null;
FileWriter fileWriter = new FileWriter(output);
try {
String sCurrentLine;
br = new BufferedReader(new FileReader( input ));
int i= 0;
while ((sCurrentLine = br.readLine()) != null) {
byte[] isoB = encode( sCurrentLine.getBytes() );
fileWriter.write(new String(isoB, Charset.forName("ISO-8859-15") ) );
fileWriter.write("\n");
System.out.println( i++ );
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
fileWriter.flush();
fileWriter.close();
if (br != null)br.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
static byte[] encode(byte[] arr){
Charset utf8charset = Charset.forName("UTF-8");
Charset iso88591charset = Charset.forName("ISO-8859-15");
ByteBuffer inputBuffer = ByteBuffer.wrap( arr );
// decode UTF-8
CharBuffer data = utf8charset.decode(inputBuffer);
// encode ISO-8559-1
ByteBuffer outputBuffer = iso88591charset.encode(data);
byte[] outputData = outputBuffer.array();
return outputData;
}
}
You need to make sure the IIS Management Console is installed.
Simply add these to your ggplot:
+ scale_x_continuous(expand = c(0, 0), limits = c(0, NA)) +
scale_y_continuous(expand = c(0, 0), limits = c(0, NA))
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0), limits = c(0,NA)) +
scale_y_continuous(expand = c(0, 0), limits = c(0, NA))
Lastly, take great care not to unintentionally exclude data off your chart. For example, a position = 'dodge'
could cause a bar to get left off the chart entirely (e.g. if its value is zero and you start the axis at zero), so you may not see it and may not even know it's there. I recommend plotting data in full first, inspect, then use the above tip to improve the plot's aesthetics.
Two ways.
i. You can put it in ApplicationController and add the filters in the controller
class ApplicationController < ActionController::Base def filter_method end end class FirstController < ApplicationController before_filter :filter_method end class SecondController < ApplicationController before_filter :filter_method end
But the problem here is that this method will be added to all the controllers since all of them extend from application controller
ii. Create a parent controller and define it there
class ParentController < ApplicationController def filter_method end end class FirstController < ParentController before_filter :filter_method end class SecondController < ParentController before_filter :filter_method end
I have named it as parent controller but you can come up with a name that fits your situation properly.
You can also define the filter method in a module and include it in the controllers where you need the filter

2009: JavaDecompiler can do a good job with a jar: since 0.2.5, All files, in JAR files, are displayed.
See also the question "How do I “decompile” Java class files?".
The JD-Eclipse doesn't seem to have changed since late 2009 though (see Changes).
So its integration with latest Eclipse (3.8, 4.2+) might be problematic.
JD-Core is actively maintained.
Both are the result of the fantastic work of (SO user) Emmanuel Dupuy.

We can convert ServerZone DateTime
to UTC and UTC to ServerZone DateTime
Simply run the following scripts to understand the conversion then modify as what you need
--Get Server's TimeZone
DECLARE @ServerTimeZone VARCHAR(50)
EXEC MASTER.dbo.xp_regread 'HKEY_LOCAL_MACHINE',
'SYSTEM\CurrentControlSet\Control\TimeZoneInformation',
'TimeZoneKeyName',@ServerTimeZone OUT
-- ServerZone to UTC DATETIME
DECLARE @CurrentServerZoneDateTime DATETIME = GETDATE()
DECLARE @UTCDateTime DATETIME = @CurrentServerZoneDateTime AT TIME ZONE @ServerTimeZone AT TIME ZONE 'UTC'
--(OR)
--DECLARE @UTCDateTime DATETIME = GETUTCDATE()
SELECT @CurrentServerZoneDateTime AS CURRENTZONEDATE,@UTCDateTime AS UTCDATE
-- UTC to ServerZone DATETIME
SET @CurrentServerZoneDateTime = @UTCDateTime AT TIME ZONE 'UTC' AT TIME ZONE @ServerTimeZone
SELECT @UTCDateTime AS UTCDATE,@CurrentServerZoneDateTime AS CURRENTZONEDATE
Note: This(AT TIME ZONE
) working on only SQL Server 2016+ and this advantage is automatically considering Daylight while converting to particular Time zone

If you are looking for performance then probably best results you'll get with bitwise right shift "10">>0
. Also multiply ("10" * 1
) or not not (~~"10"
). All of them are much faster of Number
and parseInt
.
They even have "feature" returning 0 for not number argument.
Here are Performance tests.
Note that another approach is to keep with the 4.0 validation behaviour, but to define your own class that derives from RequestValidator
and set:
<httpRuntime requestValidationType="YourNamespace.YourValidator" />
(where YourNamespace.YourValidator
is well, you should be able to guess...)
This way you keep the advantages of 4.0s behaviour (specifically, that the validation happens earlier in the processing), while also allowing the requests you need to let through, through.
You can add "_CRT_SECURE_NO_WARNINGS" in Preprocessor Definitions.
Right-click your project->Properties->Configuration Properties->C/C++ ->Preprocessor->Preprocessor Definitions.
I stumbled onto this question while trying to understand how to remove every occurrence of an element from an Array. Here's a comparison of splice
and delete
for removing every 'c'
from the items
Array.
var items = ['a', 'b', 'c', 'd', 'a', 'b', 'c', 'd'];
while (items.indexOf('c') !== -1) {
items.splice(items.indexOf('c'), 1);
}
console.log(items); // ["a", "b", "d", "a", "b", "d"]
items = ['a', 'b', 'c', 'd', 'a', 'b', 'c', 'd'];
while (items.indexOf('c') !== -1) {
delete items[items.indexOf('c')];
}
console.log(items); // ["a", "b", undefined, "d", "a", "b", undefined, "d"]

If you want to install a npm module globally, make sure to use the new -g
flag, for example:
npm install forever -g
The general recommendations concerning npm module installation since 1.0rc (taken from blog.nodejs.org):
- If you’re installing something that you want to use in your program, using require('whatever'), then install it locally, at the root of your project.
- If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your PATH environment variable.
I just recently used this recommendations and it went down pretty smoothly. I installed forever globally (since it is a command line tool) and all my application modules locally.
However, if you want to use some modules globally (i.e. express or mongodb), take this advice (also taken from blog.nodejs.org):
Of course, there are some cases where you want to do both. Coffee-script and Express both are good examples of apps that have a command line interface, as well as a library. In those cases, you can do one of the following:
- Install it in both places. Seriously, are you that short on disk space? It’s fine, really. They’re tiny JavaScript programs.
- Install it globally, and then npm link coffee-script or npm link express (if you’re on a platform that supports symbolic links.) Then you only need to update the global copy to update all the symlinks as well.
The first option is the best in my opinion. Simple, clear, explicit. The second is really handy if you are going to re-use the same library in a bunch of different projects. (More on npm link in a future installment.)
I did not test one of those variations, but they seem to be pretty straightforward.
Build on stangls's answer, I put this script in my PATH (even on Windows) as git-bh:
That allows me to look for all commits where a word was involved:
git bh path/to/myfile myWord
Script:
#!/bin/bash
f=$1
shift
csha=""
{ git log --pretty=format:%H -- "$f"; echo; } | {
while read hash; do
res=$(git blame -L"/$1/",+1 $hash -- "$f" 2>/dev/null | sed 's/^/ /')
sha=${res%% (*}
if [[ "${res}" != "" && "${csha}" != "${sha}" ]]; then
echo "--- ${hash}"
echo "${res}"
csha="${sha}"
fi
done
}
With itertools
you will obtain another generator object so in most of the cases you will need another step the take the first N elements (N
). There are at least two simpler solutions (a little bit less efficient in terms of performance but very handy) to get the elements ready to use from a generator
:
Using list comprehension:
first_N_element=[generator.next() for i in range(N)]
Otherwise:
first_N_element=list(generator)[:N]
Where N
is the number of elements you want to take (e.g. N=5 for the first five elements).

or you can give specific offsets to make button position where you want simply with bootstrap grid system,
<div class="col-md-offset-4 col-md-2 col-md-offset-5">
<input type="submit" class="btn btn-block" value="submit"/>
this way, also let you specify button size if you set btn-block. sure, this will only work md size range, if you want to set other sizes too, use xs,sm,lg.
they're not really ordered, but you can do:
var first;
for (var i in obj) {
if (obj.hasOwnProperty(i) && typeof(i) !== 'function') {
first = obj[i];
break;
}
}
the .hasOwnProperty()
is important to ignore prototyped objects.

Here is how to create a DataFrame where each series is a row.
For a single Series (resulting in a single-row DataFrame):
series = pd.Series([1,2], index=['a','b'])
df = pd.DataFrame([series])
For multiple series with identical indices:
cols = ['a','b']
list_of_series = [pd.Series([1,2],index=cols), pd.Series([3,4],index=cols)]
df = pd.DataFrame(list_of_series, columns=cols)
For multiple series with possibly different indices:
list_of_series = [pd.Series([1,2],index=['a','b']), pd.Series([3,4],index=['a','c'])]
df = pd.concat(list_of_series, axis=1).transpose()
To create a DataFrame where each series is a column, see the answers by others. Alternatively, one can create a DataFrame where each series is a row, as above, and then use df.transpose()
. However, the latter approach is inefficient if the columns have different data types.

If you just want to make sure a certain file exists (f.ex. because it shoud be created in a different way than via ansible) and fail if it doesn't, then you can do this:

check_mode: no # always run
changed_when: false # doesn't change anything
This is a matplotlib question, and you can get around this by using a backend that doesn't display to the user, e.g. 'Agg':
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.savefig('/tmp/test.png')
EDIT: If you don't want to lose the ability to display plots, turn off Interactive Mode, and only call plt.show()
when you are ready to display the plots:
import matplotlib.pyplot as plt
# Turn interactive plotting off
plt.ioff()
# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('/tmp/test0.png')
plt.close(fig)
# Create a new figure, plot into it, then don't close it so it does get displayed
plt.figure()
plt.plot([1,3,2])
plt.savefig('/tmp/test1.png')
# Display all "open" (non-closed) figures
plt.show()

As far as I know Angular-cli file can't be created via a command like Package-lock file, If you want to create it, you have to do it manually.
You can type ng new to create a new angular project
Locate its .angular-cli.json file
Copy all its content
Create a folder in your original project, and name it .angular-cli.json
Paste what copied from new project in newly created angular cli file of original project.
Locate this line in angular cli file you created, and change the name field to original project's name. You can find the project name in package.json file
project": { "name": "<name of the project>" },
However, in newer angular version now it uses angular.json instead of angular-cli.json.
You can use the information schema views:
SELECT DISTINCT TABLE_SCHEMA, TABLE_NAME
FROM Information_Schema.Columns
WHERE COLUMN_NAME = 'ID'
Here's the MSDN reference for the "Columns" view: http://msdn.microsoft.com/en-us/library/ms188348.aspx
I ran into the same issue with CLion 1.2.1 (at the time of writing this answer) after updating Windows 10. It was working fine before I had updated my OS. My OS is installed in C:\ drive and CLion 1.2.1 and Cygwin (64-bit) are installed in D:\ drive.
The issue seems to be with CMake. I am using Cygwin. Below is the short answer with steps I used to fix the issue.
SHORT ANSWER (should be similar for MinGW too but I haven't tried it):
LONG ANSWER:
Below are the detailed steps that solved this issue for me:
Uninstall/delete the previous version of Cygwin (MinGW in your case)
Make sure that CLion is up-to-date
Run Cygwin setup (x64 for my 64-bit OS)
Install at least the following packages for Cygwin:
gcc
g++
make
Cmake
gdb
Make sure you are installing the correct versions of the above packages that CLion requires. You can find the required version numbers at CLion's Quick Start section (I cannot post more than 2 links until I have more reputation points).
Next, you need to add Cygwin (or MinGW) to your Windows Environment Variable called 'Path'. You can Google how to find environment variables for your version of Windows
[On Win 10, right-click on 'This PC' and select Properties -> Advanced system settings -> Environment variables... -> under 'System Variables' -> find 'Path' -> click 'Edit']
Add the 'bin' folder to the Path variable. For Cygwin, I added:
D:\cygwin64\bin
Start CLion and go to 'Settings' either from the 'Welcome Screen' or from File -> Settings
Select 'Build, Execution, Deployment' and then click on 'Toolchains'
Your 'Environment' should show the correct path to your Cygwin installation directory (or MinGW)
For 'CMake executable', select 'Use bundled CMake x.x.x' (3.3.2 in my case at the time of writing this answer)
'Debugger' shown to me says 'Cygwin GDB GNU gdb (GDB) 7.8' [too many gdb's in that line ;-)]
Below that it should show a checkmark for all the categories and should also show the correct path to 'make', 'C compiler' and 'C++ compiler'
See screenshot: Check all paths to the compiler, make and gdb
See screenshot: Check the configuration to run the project
There should be no errors in the console window. You will see that the 'Run' -> 'Build' option is now active
Build your project and then run the project. You should see the output in the terminal window
Hope this helps! Good luck and enjoy CLion.

Users of Stack Overflow can earn reputation points and \"badges\"; for example, a person is awarded 10 reputation points for receiving an \"up\" vote on an answer given to a question, and can receive badges for their valued contributions, which represents a kind of gamification of the traditional Q&A site or forum. All user-generated content is licensed under a Creative Commons Attribute-ShareAlike license. Questions are closed in order to allow low quality questions to improve. Jeff Atwood stated in 2010 that duplicate questions are not seen as a problem but rather they constitute an advantage if such additional questions drive extra traffic to the site by multiplying relevant keyword hits in search engines.\nAs of April 2014, Stack Overflow has over 2,700,000 registered users and more than 7,100,000 questions. Based on the type of tags assigned to questions, the top eight most discussed topics on the site are: Java, JavaScript, C#, PHP, Android, jQuery, Python and HTML."

I know it been asked a long time ago, but I thought a concrete example might help.
The problem, as the Traceback says, comes from the line x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] )
. Let's replace it in its context:
i + 1 >= len(x)
<=> i >= 0
, the element x[i+1]
doesn't exist. Here, this element doesn't exist since the beginning of the for loop.To solve this, you must replace x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] )
by x.append(x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ))
.
This for sure is an old topic but I want to add up to the voices to crop maybe new ideas. To address the WARNING issue under discussions, all you need to do is to set one of your table columns to a PRIMARY KEY constraint.
For anybody who's still searching:
inherit your own style for Holo buttonbars:
<style name="yourStyle" parent="@android:style/Holo.ButtonBar">
...
</style>
or Holo Light:
<style name="yourStyle" parent="@android:style/Holo.Light.ButtonBar">
...
</style>
and for borderless Holo buttons:
<style name="yourStyle" parent="@android:style/Widget.Holo.Button.Borderless.Small">
...
</style>
or Holo Light:
<style name="yourStyle" parent="@android:style/Widget.Holo.Light.Button.Borderless.Small">
...
</style>
Make a backup!
Then you need to set the default char sets on the database. This does not convert existing tables, it only sets the default for newly created tables.
ALTER DATABASE dbname CHARACTER SET utf8 COLLATE utf8_general_ci;
Then, you will need to convert the char set on all existing tables and their columns. This assumes that your current data is actually in the current char set. If your columns are set to one char set but your data is really stored in another then you will need to check the MySQL manual on how to handle this.
ALTER TABLE tbl_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
As JGuo and CorySimmons mentioned, you can use the clickable behaviour of a stylable label, hiding the less flexible file input element.

When i try create another package
under the Java folder
this error will happen
But When i moved this special package under the main package

I'm testing on real android device .(Sumsung J2)
You can go to method of same controller..using this line , and if you want to pass some parameters to that action it can be done by writing inside ( new { } ).. Note:- you can add as many parameter as required.
@Html.ActionLink("MethodName", new { parameter = Model.parameter })
Your understanding is correct.
You would do this in many cases. One example is in a relationship like OrderHeader
and OrderDetail
. The PK in OrderHeader
might be OrderNumber
. The PK in OrderDetail
might be OrderNumber
AND LineNumber
. If it was either of those two, it would not be unique, but the combination of the two is guaranteed unique.
The alternative is to use a generated (non-intelligent) primary key, for example in this case OrderDetailId
. But then you would not always see the relationship as easily. Some folks prefer one way; some prefer the other way.
For Xamarin Android this was the only solution that worked for me: another stack overflow post
If you are using AndroidClientHandler
, you need to supply a SSLSocketFactory
and a custom implementation of HostnameVerifier
with all checks disabled. To do this, you’ll need to subclass AndroidClientHandler
and override the appropriate methods.
internal class BypassHostnameVerifier : Java.Lang.Object, IHostnameVerifier
{
public bool Verify(string hostname, ISSLSession session)
{
return true;
}
}
internal class InsecureAndroidClientHandler : AndroidClientHandler
{
protected override SSLSocketFactory ConfigureCustomSSLSocketFactory(HttpsURLConnection connection)
{
return SSLCertificateSocketFactory.GetInsecure(1000, null);
}
protected override IHostnameVerifier GetSSLHostnameVerifier(HttpsURLConnection connection)
{
return new BypassHostnameVerifier();
}
}
And then
var httpClient = new System.Net.Http.HttpClient(new InsecureAndroidClientHandler());
ntd's anwser didn't solve my problem. For those in same situation, here is how I finally handled this error: Just utf8_encode each of your results.
while($row = mysql_fetch_assoc($result)){
$rows[] = array_map('utf8_encode', $row);
}
Hope it helps!
Set the CSS position: relative;
on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:
position: absolute;
bottom: 0;
right: 0;
If you need to space the text farther away from the edge, you could change 0
to 2px
or similar.
So you're trying to get the search term and category into the URL?
I would advise against this as you'll have to deal with multi-word search terms etc, and could end up with all manner of unpleasantness with disallowed characters.
I would suggest POSTing the data, sanitising it and then returning a results page.
Laravel routing is not designed to accept GET requests from forms, it is designed to use URL segments as get parameters, and built around that idea.
Based on the following plunk, consider the following HTML markup:
<body>
<div log='some-div'></div>
</body>
With the following directive declaration:
myApp.directive('log', function() {
return {
controller: function( $scope, $element, $attrs, $transclude ) {
console.log( $attrs.log + ' (controller)' );
},
compile: function compile( tElement, tAttributes ) {
console.log( tAttributes.log + ' (compile)' );
return {
pre: function preLink( scope, element, attributes ) {
console.log( attributes.log + ' (pre-link)' );
},
post: function postLink( scope, element, attributes ) {
console.log( attributes.log + ' (post-link)' );
}
};
}
};
});
The console output will be:
some-div (compile)
some-div (controller)
some-div (pre-link)
some-div (post-link)
We can see that compile
is executed first, then controller
, then pre-link
and last is post-link
.
Note: The following does not apply to directives that render their children in their link function. Quite a few Angular directives do so (like ngIf, ngRepeat, or any directive with
transclude
). These directives will natively have theirlink
function called before their child directivescompile
is called.
The original HTML markup is often made of nested elements, each with its own directive. Like in the following markup (see plunk):
<body>
<div log='parent'>
<div log='..first-child'></div>
<div log='..second-child'></div>
</div>
</body>
The console output will look like this:
// The compile phase
parent (compile)
..first-child (compile)
..second-child (compile)
// The link phase
parent (controller)
parent (pre-link)
..first-child (controller)
..first-child (pre-link)
..first-child (post-link)
..second-child (controller)
..second-child (pre-link)
..second-child (post-link)
parent (post-link)
We can distinguish two phases here - the compile phase and the link phase.
When the DOM is loaded Angular starts the compile phase, where it traverses the markup top-down, and calls compile
on all directives. Graphically, we could express it like so:
It is perhaps important to mention that at this stage, the templates the compile function gets are the source templates (not instance template).
DOM instances are often simply the result of a source template being rendered to the DOM, but they may be created by ng-repeat
, or introduced on the fly.
Whenever a new instance of an element with a directive is rendered to the DOM, the link phase starts.
In this phase, Angular calls controller
, pre-link
, iterates children, and call post-link
on all directives, like so:
Another way is configuring ~/.curlrc
like this
-w "\n\n==== cURL measurements stats ====\ntotal: %{time_total} seconds \nsize: %{size_download} bytes \ndnslookup: %{time_namelookup} seconds \nconnect: %{time_connect} seconds \nappconnect: %{time_appconnect} seconds \nredirect: %{time_redirect} seconds \npretransfer: %{time_pretransfer} seconds \nstarttransfer: %{time_starttransfer} seconds \ndownloadspeed: %{speed_download} byte/sec \nuploadspeed: %{speed_upload} byte/sec \n\n"

Typically, a cache should keep objects around some time and shall expose of them some time later. What is a good time to hold an object depends on the use case. I wanted this thing to be simple, no threads or schedulers. This approach works for me. Unlike SoftReference
s, objects are guaranteed to be available some minimum amount of time. However, the do not stay around in memory until the sun turns into a red giant.
As useage example think of a slowly responding system that shall be able to check if a request has been done quite recently, and in that case not to perform the requested action twice, even if a hectic user hits the button several times. But, if the same action is requested some time later, it shall be performed again.
class Cache<T> {
long avg, count, created, max, min;
Map<T, Long> map = new HashMap<T, Long>();
/**
* @param min minimal time [ns] to hold an object
* @param max maximal time [ns] to hold an object
*/
Cache(long min, long max) {
created = System.nanoTime();
this.min = min;
this.max = max;
avg = (min + max) / 2;
}
boolean add(T e) {
boolean result = map.put(e, Long.valueOf(System.nanoTime())) != null;
onAccess();
return result;
}
boolean contains(Object o) {
boolean result = map.containsKey(o);
onAccess();
return result;
}
private void onAccess() {
count++;
long now = System.nanoTime();
for (Iterator<Entry<T, Long>> it = map.entrySet().iterator(); it.hasNext();) {
long t = it.next().getValue();
if (now > t + min && (now > t + max || now + (now - created) / count > t + avg)) {
it.remove();
}
}
}
}
It sounds like you want a sparse array. A normal array would have 24 items in it, but a sparse array would have 3. In Perl we emulate sparse arrays with hashes:
#!/usr/bin/perl
use strict;
use warnings;
my %sparse;
@sparse{0, 5, 23} = (1 .. 3);
print "there are ", scalar keys %sparse, " items in the sparse array\n",
map { "\t$sparse{$_}\n" } sort { $a <=> $b } keys %sparse;
The keys
function in scalar context will return the number of items in the sparse array. The only downside to using a hash to emulate a sparse array is that you must sort the keys before iterating over them if their order is important.
You must also remember to use the delete
function to remove items from the sparse array (just setting their value to undef is not enough).
Another way of doing this is that first you remove the class modal-open, which closes the modal. Then you remove the class modal-backdrop that removes the grayish cover of the modal.
Following code can be used:
$('body').removeClass('modal-open')
$('.modal-backdrop').remove()
Try this:
jQuery('#main').css('opacity', '0.6');
or
jQuery('#main').css({'filter':'alpha(opacity=60)', 'zoom':'1', 'opacity':'0.6'});
if you want to support IE7, IE8 and so on.
Paramiko supports SFTP. I've used it, and I've used Twisted. Both have their place, but you might find it easier to start with Paramiko.
Use if-let block with Data to prevent app crash & safe execution of code, as function UIImagePNGRepresentation returns an optional value.
if let img = UIImage(named: "TestImage.png") {
if let data:Data = UIImagePNGRepresentation(img) {
// Handle operations with data here...
}
}
Note: Data is Swift 3 class. Use Data instead of NSData with Swift 3
Generic image operations (like png & jpg both):
if let img = UIImage(named: "TestImage.png") { //UIImage(named: "TestImage.jpg")
if let data:Data = UIImagePNGRepresentation(img) {
handleOperationWithData(data: data)
} else if let data:Data = UIImageJPEGRepresentation(img, 1.0) {
handleOperationWithData(data: data)
}
}
*******
func handleOperationWithData(data: Data) {
// Handle operations with data here...
if let image = UIImage(data: data) {
// Use image...
}
}
By using extension:
extension UIImage {
var pngRepresentationData: Data? {
return UIImagePNGRepresentation(img)
}
var jpegRepresentationData: Data? {
return UIImageJPEGRepresentation(self, 1.0)
}
}
*******
if let img = UIImage(named: "TestImage.png") { //UIImage(named: "TestImage.jpg")
if let data = img.pngRepresentationData {
handleOperationWithData(data: data)
} else if let data = img.jpegRepresentationData {
handleOperationWithData(data: data)
}
}
*******
func handleOperationWithData(data: Data) {
// Handle operations with data here...
if let image = UIImage(data: data) {
// Use image...
}
}
Text files in Windows don't have a format. There's an unofficial convention that if the file starts with the BOM codepoint in UTF-8 format that it's UTF-8, but that convention isn't universally supported. That would be the 3 byte sequence "\xef\xbf\xbe"
, i.e. ￾
in the Latin-1 character set.
To include an optional minus sign and to disallow numbers like 015
(which can be mistaken for octal numbers) write:
-?(0|([1-9]\d*))(\.\d+)?
Actually the last one is not weird. Code is setting the timezone for working instead of working2.
SimpleDateFormat working2 = new SimpleDateFormat("hh:mm:ss");
working.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
kk goes from 1 to 24, HH from 0 to 23 and hh from 1 to 12 (AM/PM).
Fixing this error gives:
24:00:00
00:00:00
01:00:00
No difference as such.

Its best practice to have TOP 1 1
always.
What if I use SELECT 1
-> If condition matches more than one record then your query will fetch all the columns records and returns 1.
What if I use SELECT TOP 1 1
-> If condition matches more than one record also, it will just fetch the existence of any row (with a self 1-valued column) and returns 1.
IF EXISTS (SELECT TOP 1 1 FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx')
BEGIN
SELECT 1

ELSE
BEGIN
SELECT 2
END
A note of personal experience in addition to both Stefan Gehrig's answer and Dave None's answer (and mmmshuddup's reply):
I was having validation problems using both \n and PHP_EOL when I used the ICS validator at http://severinghaus.org/projects/icv/
I learned I had to use \r\n in order to get it to validate properly, so this was my solution:
function dateToCal($timestamp) {
return date('Ymd\Tgis\Z', $timestamp);
}
function escapeString($string) {
return preg_replace('/([\,;])/','\\\$1', $string);
}
$eol = "\r\n";
$load = "BEGIN:VCALENDAR" . $eol .
"VERSION:2.0" . $eol .
"PRODID:-//project/author//NONSGML v1.0//EN" . $eol .
"CALSCALE:GREGORIAN" . $eol .
"BEGIN:VEVENT" . $eol .
"DTEND:" . dateToCal($end) . $eol .
"UID:" . $id . $eol .
"DTSTAMP:" . dateToCal(time()) . $eol .
"DESCRIPTION:" . htmlspecialchars($title) . $eol .
"URL;VALUE=URI:" . htmlspecialchars($url) . $eol .
"SUMMARY:" . htmlspecialchars($description) . $eol .
"DTSTART:" . dateToCal($start) . $eol .
"END:VEVENT" . $eol .
"END:VCALENDAR";
$filename="Event-".$id;
// Set the headers
header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: attachment; filename=' . $filename);
// Dump load
echo $load;
That stopped my parse errors and made my ICS files validate properly.
Collection Initializer inside Object Initializer:
MailMessage mail = new MailMessage {
To = { new MailAddress("[email protected]"), new MailAddress("[email protected]") },
Subject = "Password Recovery"
};
You can initialize a whole tree in a single expression.
The syntax is
EXEC mySchema.myPackage.myProcedure@myRemoteDB( 'someParameter' );
I found that if the value passed is a string type, it must be followed by 'px' (i.e. 90px), where if the value is an integer, it will append the px automatically. the width and height properties are more forgiving (either type works).
var x = "90";
var y = "120"
$(selector).css( { left: x, top: y } ) //doesn't work
$(selector).css( { left: x + "px", top: y + "px" } ) //does work
x = 90;
y = 120;
$(selector).css( { left: x, top: y } ) //does work

The classic gotcha in this scenario is what to do with people born on the 29th day of February. Example: you need to be aged 18 to vote, drive a car, buy alcohol, etc ... if you are born on 2004-02-29, what is the first day that you are permitted to do such things: 2022-02-28, or 2022-03-01? AFAICT, mostly the first, but a few killjoys might say the latter.
Here's code that caters for the 0.068% (approx) of the population born on that day:

There are multiple ways to achieve this. Here, I have explained the two most common approaches.
1. You can use axios interceptors to intercept any requests and add authorization headers.
// Add a request interceptor
axios.interceptors.request.use(function (config) {
const token = store.getState().session.token;
config.headers.Authorization = token;
return config;
});
2. From the documentation of axios
you can see there is a mechanism available which allows you to set default header which will be sent with every request you make.
axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
So in your case:
axios.defaults.headers.common['Authorization'] = store.getState().session.token;
If you want, you can create a self-executable function which will set authorization header itself when the token is present in the store.
(function() {
String token = store.getState().session.token;
if (token) {
axios.defaults.headers.common['Authorization'] = token;
} else {
axios.defaults.headers.common['Authorization'] = null;
/*if setting null does not remove `Authorization` header then try
delete axios.defaults.headers.common['Authorization'];
*/
}
})();
Now you no longer need to attach token manually to every request. You can place the above function in the file which is guaranteed to be executed every time (e.g: File which contains the routes).
Hope it helps :)
SELECT * FROM table WHERE col >= '2010-10-01' AND col <= '2010-10-31'
You can add custom colors using bootstrap theming in your config file for example variables.scss
and make sure you import that file before bootstrap when compiling.
$theme-colors: (
"whatever": #900
);
Now you can do .btn-whatever
There are plenty of answers here explaining what you could do (I use the different field name one) but the simple (and as-yet unstated) answer to your question is 'no' - you can't have a different text and value using just HTML.

and the database specified in the URL does not yet exist, a new (empty) database is created."—H2 Database.
Addendum: @Thomas Mueller shows how to Execute SQL on Connection, but I sometimes just create and populate in the code, as suggested below.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
/** @see http://stackoverflow.com/questions/5225700 */
public class H2MemTest {
public static void main(String[] args) throws Exception {
Connection conn = DriverManager.getConnection("jdbc:h2:mem:", "sa", "");
Statement st = conn.createStatement();
st.execute("create table customer(id integer, name varchar(10))");
st.execute("insert into customer values (1, 'Thomas')");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select name from customer");
while (rset.next()) {
String name = rset.getString(1);
System.out.println(name);
}
}
}
If you guys still interested, here is my workaround based on Guzzle middleware feature:
Create JsonAwaraResponse
that will decode JSON response by Content-Type
HTTP header, if not - it will act as standard Guzzle Response:
<?php
namespace GuzzleHttp\Psr7;
class JsonAwareResponse extends Response
{
/**
* Cache for performance
* @var array
*/
private $json;
public function getBody()
{
if ($this->json) {
return $this->json;
}
// get parent Body stream
$body = parent::getBody();
// if JSON HTTP header detected - then decode
if (false !== strpos($this->getHeaderLine('Content-Type'), 'application/json')) {
return $this->json = \json_decode($body, true);
}
return $body;
}
}
Create Middleware which going to replace Guzzle PSR-7 responses with above Response implementation:
<?php
$client = new \GuzzleHttp\Client();
/** @var HandlerStack $handler */
$handler = $client->getConfig('handler');
$handler->push(\GuzzleHttp\Middleware::mapResponse(function (\Psr\Http\Message\ResponseInterface $response) {
return new \GuzzleHttp\Psr7\JsonAwareResponse(
$response->getStatusCode(),
$response->getHeaders(),
$response->getBody(),
$response->getProtocolVersion(),
$response->getReasonPhrase()
);
}), 'json_decode_middleware');
After this to retrieve JSON as PHP native array use Guzzle as always:
$jsonArray = $client->get('http://httpbin.org/headers')->getBody();
Tested with guzzlehttp/guzzle 6.3.3
The -m
switch of PuTTY takes a path to a script file as an argument, not a command.
Reference: https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-m
So you have to save your command (command_run
) to a plain text file (e.g. c:\path\command.txt
) and pass that to PuTTY:
putty.exe -ssh user@host -pw password -m c:\path\command.txt
Though note that you should use Plink (a command-line connection tool from PuTTY suite). It's a console application, so you can redirect its output to a file (what you cannot do with PuTTY).
A command-line syntax is identical, an output redirection added:
plink.exe -ssh user@host -pw password -m c:\path\command.txt > output.txt
See Using the command-line connection tool Plink.
And with Plink, you can actually provide the command directly on its command-line:
plink.exe -ssh user@host -pw password command > output.txt
Similar questions:

You can also use String.valueOf((Object) nullableString)
like
switch (String.valueOf((Object) nullableString)) {
case "someCase"
//...
break;
...
case "null": // or default:
//...
break;
}
See interesting SO Q/A: Why does String.valueOf(null) throw a NullPointerException
It is normally provided by the browser and hard to change, so the only way around it will be a CSS/JavaScript hack,

Django employs a slightly modified kind of MVC. There's no concept of a "controller" in Django. The closest proxy is a "view", which tends to cause confusion with MVC converts because in MVC a view is more like Django's "template".
In Django, a "model" is not merely a database abstraction. In some respects, it shares duty with the Django's "view" as the controller of MVC. It holds the entirety of behavior associated with an instance. If that instance needs to interact with an external API as part of it's behavior, then that's still model code. In fact, models aren't required to interact with the database at all, so you could conceivable have models that entirely exist as an interactive layer to an external API. It's a much more free concept of a "model".

li = d.Items[i];
if (li.Value == val)

Token Based (Security / Authentication)
means that In order for us to prove that we’ve access we first have to receive the token. In a real life scenario, the token could be an access card to building, it could be the key to the lock to your house. In order for you to retrieve a key card for your office or the key to your home, you first need to prove who you are, and that you in fact do have access to that token. It could be something as simple as showing someone your ID or giving them a secret password. So imagine I need to get access to my office. I go down to the security office, I show them my ID, and they give me this token, which lets me into the building. Now I have unrestricted access to do whatever I want inside the building, as long as I have my token with me.
What’s the benefit of token based security?
If we think back on the insecure API, what we had to do in that case was that we had to provide our password for everything that we wanted to do.
Imagine that every time we enter a door in our office, we have to give everyone sitting next to the door our password. Now that would be pretty bad, because that means that anyone inside our office could take our password and impersonate us, and that’s pretty bad. Instead, what we do is that we retrieve the token, of course together with password, but we retrieve that from one person. And then we can use this token wherever we want inside the building. Of course if we lose the token, we have the same problem as if someone else knew our password, but that leads us into things like how do we make sure that if we lose the token, we can revoke the access, and maybe the token shouldn’t live for longer than 24hours, so the next day that we come to the office, we need to show our ID again. But still, there’s just one person that we show the ID to, and that’s the security guard sitting where we retrieve the tokens.
I was getting the same error and the problem was solved by updating my numpy installation from 1.7.1 to 1.12.1
pip install -U numpy
The followings were my cmd sequence when the error was occurred, slightly different from the above:

Here I found a solution by comparing buttons in a button-group element. The simple solution is to get the one with the largest width and set the width to the other buttons. So they can have a equal width.
function EqualizeButtons(parentElementId) {
var longest = 0;
var element = $(parentElementId);
element.find(".btn:not(.button-controlled)").each(function () {
$(this).addClass('button-controlled');
var width = $(this).width();
if (longest < width) longest = width;
}).promise().done(function () {
$('.button-controlled').width(longest);
});
}
It worked like a charm.
You can implement your OTF
font using @font-face like:
@font-face {
font-family: GraublauWeb;
src: url("path/GraublauWeb.otf") format("opentype");
}
@font-face {
font-family: GraublauWeb;
font-weight: bold;
src: url("path/GraublauWebBold.otf") format("opentype");
}
// Edit: OTF now works in most browsers, see comments
However if you want to support a wide variety of browsers i would recommend you to switch to WOFF
and TTF
font types. WOFF
type is implemented by every major desktop browser, while the TTF
type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.
@font-face {
font-family: GraublauWeb;
src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf") format("truetype");
}
If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:
@font-face {
font-family: GraublauWeb;
src: url("webfont.eot"); /* IE9 Compat Modes */
src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
url("webfont.woff") format("woff"), /* Modern Browsers */
url("webfont.ttf") format("truetype"), /* Safari, Android, iOS */
url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}
You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:
hope this helps
Sql Server 2012 has a function that will create the date based on the parts (DATEFROMPARTS). For the rest of us, here is a db function I created that will determine the date from the parts (thanks @Charles)...
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id(N'[dbo].[func_DateFromParts]'))
DROP FUNCTION [dbo].[func_DateFromParts]
GO
CREATE FUNCTION [dbo].[func_DateFromParts]
(
@Year INT,
@Month INT,
@DayOfMonth INT,
@Hour INT = 0, -- based on 24 hour clock (add 12 for PM :)
@Min INT = 0,
@Sec INT = 0
)
RETURNS DATETIME
AS
BEGIN
RETURN DATEADD(second, @Sec,
DATEADD(minute, @Min,
DATEADD(hour, @Hour,
DATEADD(day, @DayOfMonth - 1,
DATEADD(month, @Month - 1,
DATEADD(Year, @Year-1900, 0))))))
END
GO
You can call it like this...
SELECT dbo.func_DateFromParts(2013, 10, 4, 15, 50, DEFAULT)
Returns...
2013-10-04 15:50:00.000
I had a problem to read/parse the object from S3 because of .get()
using Python 2.7 inside an AWS Lambda.
I added json to the example to show it became parsable :)
import boto3
import json
s3 = boto3.client('s3')
obj = s3.get_object(Bucket=bucket, Key=key)
j = json.loads(obj['Body'].read())
NOTE (for python 2.7): My object is all ascii, so I don't need .decode('utf-8')
NOTE (for python 3.6+): We moved to python 3.6 and discovered that read()
now returns bytes
so if you want to get a string out of it, you must use:
j = json.loads(obj['Body'].read().decode('utf-8'))
In command prompt:
SET PATH = "%PATH%;%SystemRoot%\Microsoft.NET\Framework\v2.0.50727"
As hinted at in yatima2975's answer, there is an additional difference:
substr()
accepts a negative starting position as an offset from the end of the string. substring()
does not.
From MDN:
If start is negative, substr() uses it as a character index from the end of the string.
So to sum up the functional differences:
substring(begin-offset, end-offset-exclusive)
where begin-offset is 0
or greater
substr(begin-offset, length)
where begin-offset may also be negative
Here you go
col-lg-2 : if the screen is large (lg) then this component will take space of 2 elements considering entire row can fit 12 elements ( so you will see that on large screen this component takes 16% space of a row)
col-lg-6 : if the screen is large (lg) then this component will take space of 6 elements considering entire row can fit 12 elements -- when applied you will see that the component has taken half the available space in the row.
Above rule is only applied when the screen is large. when the screen is small this rule is discarded and only one component per row is shown.
Below image shows various screen size widths :
This worked for me --
$("#dialog-confirm").html('Do you want to permanently delete this?');
$( "#dialog-confirm" ).dialog({
resizable: false,
title:'Confirm',
modal: true,
buttons: {
Cancel: function() {
$( this ).dialog( "close" );
},
OK:function(){
$('#loading').show();
$.ajax({
type:'post',
url:'ajax.php',
cache:false,
data:{action:'do_something'},
async:true,
success:function(data){
var resp = JSON.parse(data);
$("#loading").hide();
$("#dialog-confirm").html(resp.msg);
$( "#dialog-confirm" ).dialog({
resizable: false,
title:'Confirm',
modal: true,
buttons: {
Close: function() {
$( this ).dialog( "close" );
}
}
});
}
});
}
}
});
Another option is to add another tag with flex: auto
style in between your tags that you want to fill in the remaining space.
https://jsfiddle.net/tsey5qu4/
The HTML:
<div class="parent">
<div class="left">Left</div>
<div class="fill-remaining-space"></div>
<div class="right">Right</div>
</div>
The CSS:
.fill-remaining-space {
flex: auto;
}
This is equivalent to flex: 1 1 auto, which absorbs any extra space along the main axis.
Check the path
import numpy
print numpy.__path__
For me this was /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy So I moved it to a temporary place
sudo mv /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy \
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy_old
and then the next time I imported numpy the path was /Library/Python/2.7/site-packages/numpy/init.pyc and all was well.
MutableList
or ArrayList
.Let's see how the methods of
MutableList
work:
var listNumbers: MutableList<Int> = mutableListOf(10, 15, 20)
// Result: 10, 15, 20
listNumbers.add(1000)
// Result: 10, 15, 20, 1000
listNumbers.add(1, 250)
// Result: 10, 250, 15, 20, 1000
listNumbers.removeAt(0)
// Result: 250, 15, 20, 1000
listNumbers.remove(20)
// Result: 250, 15, 1000
for (i in listNumbers) {
println(i)
}
Let's see how the methods of
ArrayList
work:
var arrayNumbers: ArrayList<Int> = arrayListOf(1, 2, 3, 4, 5)
// Result: 1, 2, 3, 4, 5
arrayNumbers.add(20)
// Result: 1, 2, 3, 4, 5, 20
arrayNumbers.remove(1)
// Result: 2, 3, 4, 5, 20
arrayNumbers.clear()
// Result: Empty
for (j in arrayNumbers) {
println(j)
}
2017 update
The original answer below assumes that the OP wants to include non-empty text node and other node types as well as elements. It doesn't seem clear to me now from the question whether this is a valid assumption.
Assuming instead you just want the element index, previousElementSibling
is now well-supported (which was not the case in 2012) and is the obvious choice now. The following (which is the same as some other answers here) will work in everything major except IE <= 8.
function getElementIndex(node) {
var index = 0;
while ( (node = node.previousElementSibling) ) {
index++;
}
return index;
}
Original answer
Just use previousSibling
until you hit null
. I'm assuming you want to ignore white space-only text nodes; if you want to filter other nodes then adjust accordingly.
function getNodeIndex(node) {
var index = 0;
while ( (node = node.previousSibling) ) {
if (node.nodeType != 3 || !/^\s*$/.test(node.data)) {
index++;
}
}
return index;
}
It's actually much easier with jQuery's promise API:
$.ajax(
type: "GET",
url: requestURL,
).then((success) =>
console.dir(success)
).failure((failureResponse) =>
console.dir(failureResponse)
)
Alternatively, you can pass in of bind
functions to each result callback; the order of parameters is: (success, failure)
. So long as you specify a function with at least 1 parameter, you get access to the response. So, for example, if you wanted to check the response text, you could simply do:
$.ajax(
type: "GET",
url: @get("url") + "logout",
beforeSend: (xhr) -> xhr.setRequestHeader("token", currentToken)
).failure((response) -> console.log "Request was unauthorized" if response.status is 401
expr(1)
has a substr subcommand:
expr substr <string> <start-index> <length>
This may be useful if you don't have bash (perhaps embedded Linux) and you don't want the extra "echo" process you need to use cut(1).
For me it was a permission problem.
enter:
mysqld --verbose --help | grep -A 1 "Default options"
[Warning] World-writable config file '/etc/mysql/my.cnf' is ignored.
So try to execute the following, and then restart the server
chmod 644 '/etc/mysql/my.cnf'
It will give mysql access to read and write to the file.
For more information about .scrollHeight
property refer to the docs:
The Element.scrollHeight read-only attribute is a measurement of the height of an element's content, including content not visible on the screen due to overflow. The scrollHeight value is equal to the minimum clientHeight the element would require in order to fit all the content in the viewpoint without using a vertical scrollbar. It includes the element padding but not its margin.
I realize this is an old question and has been answered but this could help someone.

Eager Execution is enabled by default, so just call .numpy()
on the Tensor object.
import tensorflow as tf
a = tf.constant([[1, 2], [3, 4]])
b = tf.add(a, 1)
a.numpy()
# array([[1, 2],
# [3, 4]], dtype=int32)
b.numpy()
# array([[2, 3],
# [4, 5]], dtype=int32)
tf.multiply(a, b).numpy()
# array([[ 2, 6],
# [12, 20]], dtype=int32)
See NumPy Compatibility for more. It is worth noting (from the docs),
Numpy array may share memory with the Tensor object. Any changes to one may be reflected in the other.
Bold emphasis mine. A copy may or may not be returned, and this is an implementation detail based on whether the data is in CPU or GPU (in the latter case, a copy has to be made from GPU to host memory).
But why am I getting AttributeError: 'Tensor' object has no attribute 'numpy'
?.
A lot of folks have commented about this issue, there are a couple of possible reasons:
tf.compat.v1.enable_eager_execution()
to enable it, or see below.If Eager Execution is disabled, you can build a graph and then run it through tf.compat.v1.Session
:
a = tf.constant([[1, 2], [3, 4]])
b = tf.add(a, 1)
out = tf.multiply(a, b)
out.eval(session=tf.compat.v1.Session())
# array([[ 2, 6],
# [12, 20]], dtype=int32)
See also TF 2.0 Symbols Map for a mapping of the old API to the new one.
Sometimes, the plt.tight_layout()
doesn't give me the best view or the view I want. Then why don't plot with arbitrary margin first and do fixing the margin after plot?
Since we got nice WYSIWYG from there.
import matplotlib.pyplot as plt
fig,ax = plt.subplots(figsize=(8,8))
plt.plot([2,5,7,8,5,3,5,7,])
plt.show()
Then paste settings into margin function to make it permanent:
fig,ax = plt.subplots(figsize=(8,8))
plt.plot([2,5,7,8,5,3,5,7,])
fig.subplots_adjust(
top=0.981,
bottom=0.049,
left=0.042,
right=0.981,
hspace=0.2,
wspace=0.2
)
plt.show()
another one:
if(this.checkValidity() == false) {
$(this).addClass('was-validated');
e.preventDefault();
e.stopPropagation();
e.stopImmediatePropagation();
return false;
}

You can use PowerShell to run b.bat as administrator from a.bat
:
set mydir=%~dp0
Powershell -Command "& { Start-Process \"%mydir%b.bat\" -verb RunAs}"
It will prompt the user with a confirmation dialog. The user chooses YES
, and then b.bat
will be run as administrator.

If you want to use 'lengthMenu' together with buttons(copy, export), you have to use this option dom: 'lBfrtip'. Here https://datatables.net/reference/option/dom you can find meaning of each symbol. For example, if you will use like this 'Bfrtip', lengthMenu will not appears.
This is how I solved it when I had a similar need:
# Some function that takes a long time to process
longprocess() {
# Sleep up to 14 seconds
sleep $((RANDOM % 15))
# Randomly exit with 0 or 1
exit $((RANDOM % 2))
}
pids=""
# Run five concurrent processes
for i in {1..5}; do
( longprocess ) &
# store PID of process
pids+=" $!"
done
# Wait for all processes to finish, will take max 14s
# as it waits in order of launch, not order of finishing
for p in $pids; do
if wait $p; then
echo "Process $p success"
else
echo "Process $p fail"
fi
done
Do this :
$(document).ready(function(){
$("#frm1").submit();
});
It works like this:

</ScrollViewer>
TextBox tb = new TextBox();
tb.TextChanged += new TextChangedEventHandler(TextBox_TextChanged);
stackPanel1.Children.Add(tb);
(1..4).each { |i|
a = 9 if i==3
puts a
}
#nil

for i in 1..4
a = 9 if i==3
puts a

In 'for' loop, local variable is still lives after each loop. In 'each' loop, local variable refreshes after each loop.
You can also add 0, use shift operators or xor:
val + 0;
val ^ 0;
val >> 0;
val >>> 0;
val << 0;
These have similar speeds as those from the others answers.
There are two primary components to PostgreSQL: the database server and a client.
There is an included client via the CLI, or like me, you might be used to tools like phpMyAdmin, so it requires a separate GUI client.
For example, on macOS: install Postgres.app
which is ~65 MB from: https://postgresapp.com/
Then follow these instructions:
$PATH
using terminal: sudo mkdir -p /etc/paths.d && echo /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee /etc/paths.d/postgresapp
pgAdmin
GUI which is about ~100 MB from: https://www.pgadmin.org/download/pgadmin-4-macos/There are two problems with this question:
Assuming you have a gray scale bitmap, you have two factors to consider:
Answer those questions, and then you might be able to find your original answer.
You have to add this permission in Info.plist for iOS 10.

Thanks to cryo for improved version that I based my tested code below:

Quoting from CrazyPenguin's reply
"For those, like me, who found that even on the new Eclipse it wasn't scaled, see here: swt-autoscale-tweaks Basically I added -Dswt.autoScale=quarter to my eclipse.ini file."
2017 Update:
Stackdriver Logging is now available for Google Apps Script. From the menu bar in the script editor, goto:
View > Stackdriver Logging
to view or stream the logs.
console.log() will write DEBUG
level messages
Example onEdit()
logging:
function onEdit (e) {
var debug_e = {
authMode: e.authMode,
range: e.range.getA1Notation(),
source: e.source.getId(),
user: e.user,
value: e.value,
oldValue: e. oldValue
}
console.log({message: 'onEdit() Event Object', eventObject: debug_e});
}
Then check the logs in the Stackdriver UI labeled onEdit() Event Object
to see the output
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
You can create an ExtensionMethod to do that!
public static class StringExtension
{
public static string Repeat(this string str, int count)
{
string ret = "";
for (var x = 0; x < count; x++)
{
ret += str;
}
return ret;
}
}
Or using @Dan Tao solution:
public static class StringExtension
{
public static string Repeat(this string str, int count)
{
if (count == 0)
return "";
return string.Concat(Enumerable.Repeat(indent, N))
}
}
If you trust the data source, you can use eval
to convert your string into a dictionary:
eval(your_json_format_string)
Example:
>>> x = "{'a' : 1, 'b' : True, 'c' : 'C'}"
>>> y = eval(x)
>>> print x
{'a' : 1, 'b' : True, 'c' : 'C'}
>>> print y
{'a': 1, 'c': 'C', 'b': True}
>>> print type(x), type(y)
<type 'str'> <type 'dict'>
>>> print y['a'], type(y['a'])
1 <type 'int'>
>>> print y['a'], type(y['b'])
1 <type 'bool'>
>>> print y['a'], type(y['c'])
1 <type 'str'>
You could use SysInternal's PsExec.
I'll add another - lists can act as purely functional data structures.
For instance, you can have completely different lists sharing the same end section
a = (1 2 3 4, ....)
b = (4 3 2 1 1 2 3 4 ...)
c = (3 4 ...)
i.e.:
b = 4 -> 3 -> 2 -> 1 -> a
c = a.next.next
without having to copy the data being pointed to by a
into b
and c
.
This is why they are so popular in functional languages, which use immutable variables - prepend
and tail
operations can occur freely without having to copy the original data - very important features when you're treating data as immutable.
It is up to the browser but they behave in similar ways.
I have tested FF, IE7, Opera and Chrome.
F5 usually updates the page only if it is modified. The browser usually tries to use all types of cache as much as possible and adds an "If-modified-since" header to the request. Opera differs by sending a "Cache-Control: no-cache".
CTRL-F5 is used to force an update, disregarding any cache. IE7 adds an "Cache-Control: no-cache", as does FF, which also adds "Pragma: no-cache". Chrome does a normal "If-modified-since" and Opera ignores the key.
If I remember correctly it was Netscape which was the first browser to add support for cache-control by adding "Pragma: No-cache" when you pressed CTRL-F5.
Edit: Updated table
The table below is updated with information on what will happen when the browser's refresh-button is clicked (after a request by Joel Coehoorn), and the "max-age=0" Cache-control-header.

Versions tested:
Notes:
Version 3.0.6 sends I and C, but 3.1.6 opens the page in a new tab, making a normal request with only "I".
Version 10.62 does nothing. 9.61 might do C unless it was a typo in my old table.
Note about Chrome 6.0.472: If you do a forced reload (like CTRL-F5) it behaves like the url is internally marked to always do a forced reload. The flag is cleared if you go to the address bar and press enter.
This seems like a very simple solution:
import numpy as np
def shuffle_in_unison(a,b):
assert len(a)==len(b)
c = np.arange(len(a))
np.random.shuffle(c)
return a[c],b[c]
a = np.asarray([[1, 1], [2, 2], [3, 3]])
b = np.asarray([11, 22, 33])
shuffle_in_unison(a,b)
Out[94]:
(array([[3, 3],
[2, 2],
[1, 1]]),
array([33, 22, 11]))
The package can be uninstalled using the same uninstall or rm command that can be used for removing installed packages. The only thing to keep in mind is that the link needs to be uninstalled globally - the --global
flag needs to be provided.
In order to uninstall the globally linked foo
package, the following command can be used (using sudo
if necessary, depending on your setup and permissions)
sudo npm rm --global foo
This will uninstall the package.
To check whether a package is installed, the npm ls
command can be used:
npm ls --global foo

I recommend you to read the following post: AngularJS: "Controller as" or "$scope"?
It describes very well the advantages of using "Controller as" to expose variables over "$scope".
I know you asked specifically about methods and not variables, but I think that it's better to stick to one technique and be consistent with it.
So for my opinion, because of the variables issue discussed in the post, it's better to just use the "Controller as" technique and also apply it to the methods.
If you are interested ONLY on relative paths like: /dashboard
, /about
etc, See other answers.
If you want to open an absolute path like: https://www.google.com
to a new tab, you have to know that Vue Router is NOT meant to handle those.
However, they seems to consider that as a feature-request. #1280. But until they do that,
Here is a little trick you can do to handle external links with vue-router.
router.js
) and add this code:/* Vue Router is not meant to handle absolute urls. */
/* So whenever we want to deal with those, we can use this.$router.absUrl(url) */
Router.prototype.absUrl = function(url, newTab = true) {
const link = document.createElement('a')
link.href = url
link.target = newTab ? '_blank' : ''
if (newTab) link.rel = 'noopener noreferrer' // IMPORTANT to add this
link.click()
}
Now, whenever we deal with absolute URLs we have a solution. For example to open google to a new tab
this.$router.absUrl('https://www.google.com)
Remember that whenever we open another page to a new tab we MUST use noopener noreferrer
.
On my 64 bit system I noticed that the following directory existed:
/usr/include/c++/4.4/x86_64-linux-gnu/32/bits
It would then make sense that on my 32 bit system that had been setup for 64bit cross compiling there should be a corresponding directory like:
/usr/include/c++/4.4/i686-linux-gnu/64/bits
I double checked and this directory did not exist. Running g++
with the verbose parameter showed that the compiler was actually looking for something in this location:

compilation terminated.
The error regarding the ignoring nonexistent directory
was the clue. Unfortunately, I still don't know what package I need to install to have this directory show up so I just copied the /usr/include/c++/4.4/x86_64-linux-gnu/bits
directory from my 64 bit machine to /usr/include/c++/4.4/i686-linux-gnu/64/bits
on my 32 machine.
Now compiling with just the -m64
works correctly. The major drawback is that this is still not the correct way to do things and I am guessing the next time Update Manager installs and update to g++ things may break.
Make sure you have the right selector, and then wait until the page is ready and that the element exists until you run the function.
$(function(){
$('#searchBar').val('hi')
});
As Derek points out, the ID is wrong as well.
Change to $('#main_search')
Here are some classes I use for long-polling in C#. There are basically 6 classes (see below).
For windows users, this can also be caused by filesystem corruption.
If all steps above do not correct the error:
chkdsk /f
on the drive your app is stored.idea
folderThis is very easy to understand if you track class and instance dictionaries.
class C:
one = 42
def __init__(self,val):
self.two=val
ci=C(50)
print(ci.__dict__)
print(C.__dict__)
The result will be like this:
{'two': 50}
{'__module__': '__main__', 'one': 42, '__init__': <function C.__init__ at 0x00000213069BF6A8>, '__dict__': <attribute '__dict__' of 'C' objects>, '__weakref__': <attribute '__weakref__' of 'C' objects>, '__doc__': None}
Note I set the full results in here but what is important that the instance ci
dict will be just {'two': 50}
, and class dictionary will have the 'one': 42
key value pair inside.
This is all you should know about that specific variables.
Change column position:
ALTER TABLE Employees
CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;
If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:
ALTER TABLE UserOrder
CHANGE order_id order_id INT(11) NOT NULL FIRST;
there is few things that you can do
SELECT GROUP_CONCAT(CAST(name AS CHAR))
FROM product
WHERE id IN (12345,12346,12347)
If you want to order by the query you can order by cast as well like below
SELECT GROUP_CONCAT(name ORDER BY name))
FROM product
WHERE id IN (12345,12346,12347)
as it says on this blog
Strings are mutable because .NET use string pool behind the scene. It means :
string name = "My Country";
string name2 = "My Country";
Both name and name2 are referring to same memory location from string pool. Now suppose you want to change name2 to :
name2 = "My Loving Country";
It will look in to string pool for the string "My Loving Country", if found you will get the reference of it other wise new string "My Loving Country" will be created in string pool and name2 will get reference of it. But it this whole process "My Country" was not changed because other variable like name is still using it. And that is the reason why string are IMMUTABLE.
StringBuilder works in different manner and don't use string pool. When we create any instance of StringBuilder :
var address = new StringBuilder(500);
It allocate memory chunk of size 500 bytes for this instance and all operation just modify this memory location and this memory not shared with any other object. And that is the reason why StringBuilder is MUTABLE.
I hope it will help.
You can try this:
NSLog(@"%@", NSStringFromCGPoint(cgPoint));
There are a number of functions provided by UIKit that convert the various CG structs into NSString
s. The reason it doesn't work is because %@
signifies an object. A CGPoint
is a C struct (and so are CGRect
s and CGSize
s).
In order to make examples from here work with Python 3.5.2, you can rewrite as follows :
import io
data =io.BytesIO(b"1, 2, 3\n4, 5, 6")
import numpy
numpy.genfromtxt(data, delimiter=",")
The reason for the change may be that the content of a file is in data (bytes) which do not make text until being decoded somehow. genfrombytes
may be a better name than genfromtxt
.
As the Jquery replaceWith() code was too bulky, tricky and complicated, here's my own solution. =)
The best way is to use outerHTML property, but it is not crossbrowsered yet, so I did some trick, weird enough, but simple.
Here is the code
var str = '<a href="http://www.com">item to replace</a>'; //it can be anything
var Obj = document.getElementById('TargetObject'); //any element to be fully replaced
if(Obj.outerHTML) { //if outerHTML is supported
Obj.outerHTML=str; ///it's simple replacement of whole element with contents of str var
}
else { //if outerHTML is not supported, there is a weird but crossbrowsered trick
var tmpObj=document.createElement("div");
tmpObj.innerHTML='<!--THIS DATA SHOULD BE REPLACED-->';
ObjParent=Obj.parentNode; //Okey, element should be parented
ObjParent.replaceChild(tmpObj,Obj); //here we placing our temporary data instead of our target, so we can find it then and replace it into whatever we want to replace to
ObjParent.innerHTML=ObjParent.innerHTML.replace('<div><!--THIS DATA SHOULD BE REPLACED--></div>',str);
}
That's all
There's Bash regular expressions. Or there's 'expr':
if expr "$link" : '/.*' > /dev/null; then
PRG="$link"
else
PRG=`dirname "$PRG"`/"$link"
fi
This can be accomplished by Unmarshaling into a map[string]json.RawMessage
.
var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)
To further parse sendMsg
, you could then do something like:
var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)
For say
, you can do the same thing and unmarshal into a string:
var str string
err = json.Unmarshal(objmap["say"], &str)
EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:
type sendMsg struct {
User string
Msg string
}
My problem was that a Cloud Access Security Broker, NetSkope, was installed on my work laptop through a software update. This was altering the certificate chain and I was still not able to connect to the server through my java client after importing the entire chain to my cacerts keystore. I disabled NetSkope and was able to successfully connect.
A very simple way is to provide some fields like <textarea style="display:none;" name="input"></textarea>
and discard all replies that have this filled in.
Another approach is to generate the whole form (or just the field names) using Javascript; few bots can run it.
Anyway, you won't do much against live "bots" from Taiwan or India, that are paid $0.03 per one posted link, and make their living that way.

You can use Collections
for to sort data:
import java.util.Collections;
import java.util.ArrayList;
import java.util.List;
public class tes
{
public static void main(String args[])
{
List<Integer> lList = new ArrayList<Integer>();
lList.add(4);
lList.add(1);
lList.add(7);
lList.add(2);
lList.add(9);
lList.add(1);
lList.add(5);
Collections.sort(lList);
for(int i=0; i<lList.size();i++ )
{
System.out.println(lList.get(i));
}
}
}
function validate()
{
var a=documents.forms["yourformname"]["yourpasswordfieldname"].value;
var b=documents.forms["yourformname"]["yourconfirmpasswordfieldname"].value;
if(!(a==b))
{
alert("both passwords are not matching");
return false;
}
return true;
}
Here is a ruby class for performing this: https://gist.github.com/4080793
Example usage:
$ gem install aws-sdk
$ irb -r ./bucket_sync_service.rb
> from_creds = {aws_access_key_id:"XXX",
aws_secret_access_key:"YYY",
bucket:"first-bucket"}
> to_creds = {aws_access_key_id:"ZZZ",
aws_secret_access_key:"AAA",
bucket:"first-bucket"}
> syncer = BucketSyncService.new(from_creds, to_creds)
> syncer.debug = true # log each object
> syncer.perform
Using Jure's script I made this, to easily "click" as many elements as you want.
I just used it Google Reader on 1600+ items and it worked perfectly (in Firefox)!
var e = document.createEvent('MouseEvents');
e.initEvent( 'click', true, true );
$(selector).each(function(){this.dispatchEvent(e);});
Tested and working!

Oracle SQL Developer doesn't support connections to PostgreSQL. Use pgAdmin to connect to PostgreSQL instead, you can get it from the following URL http://www.pgadmin.org/download/windows.php
Much simpler using only SimpleDateFormat, without passing all the parameters individual:
String FORMATER = "yyyy-MM-dd'T'HH:mm:ss'Z'";
DateFormat format = new SimpleDateFormat(FORMATER);
Date date = new Date();
XMLGregorianCalendar gDateFormatted =
DatatypeFactory.newInstance().newXMLGregorianCalendar(format.format(date));
Full example here.
Note: This is working only to remove the last 2 fields: milliseconds and timezone or to remove the entire time component using formatter yyyy-MM-dd
.
That's called SQL INJECTION. The '
tries to open/close a string in your mysql query. You should always escape any string that gets into your queries.
for example,
instead of this:
"VALUES ('$sender_id') "
do this:
"VALUES ('". mysql_real_escape_string($sender_id) ."') "
(or equivalent, of course)
However, it's better to automate this, using PDO, named parameters, prepared statements or many other ways. Research about this and SQL Injection (here you have some techniques).
Hope it helps. Cheers
The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.
To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".
To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".
Explanation:
From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):
4.3.8 ‘Local echo’
With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)
Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.
4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.
If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.
Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)
Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.
Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.
Here's the function from Naveed Rafi's answer converted to Swift if anyone else is looking for it:
func isSameDate(#date1: NSDate, date2: NSDate) -> Bool {
let calendar = NSCalendar()
let date1comp = calendar.components(.YearCalendarUnit | .MonthCalendarUnit | .DayCalendarUnit, fromDate: date1)
let date2comp = calendar.components(.YearCalendarUnit | .MonthCalendarUnit | .DayCalendarUnit, fromDate: date2)
return (date1comp.year == date2comp.year) && (date1comp.month == date2comp.month) && (date1comp.day == date2comp.day)
}
I needed this as well, and with the help of Bombe's answer + some fiddling around, I got it working. Here's the recipe:
1. cd /path/to/git/localrepo
2. svn mkdir --parents protocol:///path/to/repo/PROJECT/trunk -m "Importing git repo"
3. git svn init protocol:///path/to/repo/PROJECT -s
4. git svn fetch
5. git rebase origin/trunk
5.1. git status
5.2. git add (conflicted-files)
5.3. git rebase --continue
5.4. (repeat 5.1.)
6. git svn dcommit
After #3 you'll get a cryptic message like this:
Using higher level of URL:
protocol:///path/to/repo/PROJECT => protocol:///path/to/repo
Just ignore that.
When you run #5, you might get conflicts. Resolve these by adding files with state "unmerged" and resuming rebase. Eventually, you'll be done; then sync back to the SVN repository, using dcommit
. That's all.
You can now synchronise from SVN to Git, using the following commands:
git svn fetch
git rebase trunk
And to synchronise from Git to SVN, use:
git svn dcommit
You might want to try this out on a local copy, before applying to a live repository. You can make a copy of your Git repository to a temporary place; simply use cp -r
, as all data is in the repository itself. You can then set up a file-based testing repository, using:
svnadmin create /home/name/tmp/test-repo
And check a working copy out, using:
svn co file:///home/name/tmp/test-repo svn-working-copy
That'll allow you to play around with things before making any lasting changes.
git svn init
If you accidentally run git svn init
with the wrong URL, and you weren't smart enough to take a backup of your work (don't ask ...), you can't just run the same command again. You can however undo the changes by issuing:
rm -rf .git/svn
edit .git/config
And remove the section [svn-remote "svn"]
section.
You can then run git svn init
anew.
It looks like not.
Put a breakpoint, when it stops switch to the console, try to set the variable. It does not error when you assign it a different value, but if you read it after the assignment, it's unmodified. :-/
For me creating a python file named template_filters.py
in my App with below content did the job
# coding=utf-8
from django.template.base import Library
register = Library()
@register.filter
def get_item(dictionary, key):
return dictionary.get(key)
usage is like what culebrón said :
{{ mydict|get_item:item.NAME }}
You actually do not want to get the path to your main class. According to your example you want to get the current working directory, i.e. directory where your program started. In this case you can just say new File(".").getAbsolutePath()
You want to add the IN()
clause to your WHERE
SELECT *
FROM `Buses`
WHERE `BusID` IN (Id1, ID2, ID3,.... put your ids here)
If you have a list of Ids stored in a table you can also do this:
SELECT *
FROM `Buses`
WHERE `BusID` IN (SELECT Id FROM table)
You may have a try for https://github.com/cls1991/pef. It will remove package with its all dependencies.
Just use IDA PRO (https://www.hex-rays.com/products/ida/index.shtml) to disassemble the file, and search for some known command line option (using Search...Text) - in that section you will then typically see all the command line options - for the program (LIB2NIST.exe) in the screenshot below, for example, it shows a documented command line option (/COM2TAG) but also some undocumented ones, like /L. Hope this helps?
STRING=(one two three four)

Here is how to build a function that returns a result set that can be queried as if it were a table:
SQL> create type emp_obj is object (empno number, ename varchar2(10));
2 /
Type created.
SQL> create type emp_tab is table of emp_obj;
2 /
Type created.
SQL> create or replace function all_emps return emp_tab
2 is
3 l_emp_tab emp_tab := emp_tab();
4 n integer := 0;
5 begin
6 for r in (select empno, ename from emp)
7 loop
8 l_emp_tab.extend;
9 n := n + 1;
10 l_emp_tab(n) := emp_obj(r.empno, r.ename);
11 end loop;
12 return l_emp_tab;
13 end;
14 /
Function created.
SQL> select * from table (all_emps);
EMPNO ENAME

I would use:
<img src="picture.jpg?20130910043254">
where "20130910043254" is the modification time of the file.
When uploading an image, its filename is not kept in the database. It is renamed as Image.jpg (to simply things out when using it). When replacing the existing image with a new one, the name doesn't change either. Just the content of the image file changes.
I think there are two types of simple solutions: 1) those which come to mind first (straightforward solutions, because they are easy to come up with), 2) those which you end up with after thinking things over (because they are easy to use). Apparently, you won't always benefit if you chose to think things over. But the second options is rather underestimated, I believe. Just think why php
is so popular ;)
For someone who needs quick reference of C# Escape Sequences that can be used in string
literals:
\t Horizontal tab (ASCII code value: 9)
\n Line feed (ASCII code value: 10)
\r Carriage return (ASCII code value: 13)
\' Single quotation mark
\" Double quotation mark
\\ Backslash
\? Literal question mark
\x12 ASCII character in hexadecimal notation (e.g. for 0x12)
\x1234 Unicode character in hexadecimal notation (e.g. for 0x1234)
It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline
which gets adjusted to current OS settings. With .Net Core it gets really important.
Try this piece of code, rather than ObjectInputStream
.
BufferedReader in = new BufferedReader (new InputStreamReader (socket.getInputStream ()));
while (true)
{
String cominginText = "";
try
{
cominginText = in.readLine ();
System.out.println (cominginText);
}
catch (IOException e)
{
//error ("System: " + "Connection to server lost!");
System.exit (1);
break;
}
}
If you specify API >= 16, Activity#finishAffinity() meets your needs.
One way is to use the Grid's select()
and dataItem()
methods.
In single selection case, select()
will return a single row which can be passed to dataItem()
var entityGrid = $("#EntitesGrid").data("kendoGrid");
var selectedItem = entityGrid.dataItem(entityGrid.select());
// selectedItem has EntityVersionId and the rest of your model
For multiple row selection select()
will return an array of rows. You can then iterate through the array and the individual rows can be passed into the grid's dataItem()
.
var entityGrid = $("#EntitesGrid").data("kendoGrid");
var rows = entityGrid.select();
rows.each(function(index, row) {
var selectedItem = entityGrid.dataItem(row);
// selectedItem has EntityVersionId and the rest of your model
});
tr:hover td {background-color:#000;}
You can do it even without the HTTP_PROXY environment variable. Try this sample:
import urllib2
proxy_support = urllib2.ProxyHandler({"http":"http://61.233.25.166:80"})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
html = urllib2.urlopen("http://www.google.com").read()
print html
In your case it really seems that the proxy server is refusing the connection.
Something more to try:
import urllib2
#proxy = "61.233.25.166:80"
proxy = "YOUR_PROXY_GOES_HERE"
proxies = {"http":"http://%s" % proxy}
url = "http://www.google.com/search?q=test"
headers={'User-agent' : 'Mozilla/5.0'}
proxy_support = urllib2.ProxyHandler(proxies)
opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler(debuglevel=1))
urllib2.install_opener(opener)
req = urllib2.Request(url, None, headers)
html = urllib2.urlopen(req).read()
print html
Edit 2014:
This seems to be a popular question / answer. However today I would use third party requests
module instead.
For one request just do:
import requests
r = requests.get("http://www.google.com",
proxies={"http": "http://61.233.25.166:80"})
print(r.text)
For multiple requests use Session
object so you do not have to add proxies
parameter in all your requests:
import requests
s = requests.Session()
s.proxies = {"http": "http://61.233.25.166:80"}
r = s.get("http://www.google.com")
print(r.text)
Try:
var myMappings = {
"Name": "10%",
"Phone": "10%",
"Address": "50%",
"Zip": "10%",
"Comments": "20%"
}
// Access is like this
myMappings["Name"] // Returns "10%"
myMappings.Name // The same thing as above
// To loop through...
for(var title in myMappings) {
// Do whatever with myMappings[title]
}
