All of these schemes, except AES and Blowfish, have known vulnerabilities and should not be used.
However, Blowfish has been replaced by Twofish.
First answer is still valid, but the API has changed in the past. Since my edit there wasn't accepted I post it as separate answer.
The method authentication()
is only used to provide the authentication method (e.g. Basic) but not any credentials.
You also shouldn't use it since it's printing the credentials plain on failure!
This his how it should look like in your build.gradle
maven {
credentials {
username "$mavenUser"
password "$mavenPassword"
}
url 'https://maven.yourcorp.net/'
}
In gradle.properties
in your userhome dir put:
mavenUser=admin
mavenPassword=admin123
Also ensure that the GRADLE_USER_HOME
is set to ~/.gradle
otherwise the properties file there won't be resolved.

https://docs.gradle.org/current/userguide/build_environment.html
and
https://docs.gradle.org/current/userguide/dependency_management.html (23.6.4.1)
If X

.To turn the option ON/OFF, follow the steps below from menu bar:

Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
Here's how i'd do it:
FN=someletters_12345_moreleters.ext
[[ ${FN} =~ _([[:digit:]]{5})_ ]] && NUM=${BASH_REMATCH[1]}
Explanation:
Bash-specific:
[[ ]]
indicates a conditional expression=~
indicates the condition is a regular expression&&
chains the commands if the prior command was successfulRegular Expressions (RE): _([[:digit:]]{5})_
_
are literals to demarcate/anchor matching boundaries for the string being matched()
create a capture group[[:digit:]]
is a character class, i think it speaks for itself{5}
means exactly five of the prior character, class (as in this example), or group must matchIn english, you can think of it behaving like this: the FN
string is iterated character by character until we see an _
at which point the capture group is opened and we attempt to match five digits. If that matching is successful to this point, the capture group saves the five digits traversed. If the next character is an _
, the condition is successful, the capture group is made available in BASH_REMATCH
, and the next NUM=
statement can execute. If any part of the matching fails, saved details are disposed of and character by character processing continues after the _
. e.g. if FN
where _1 _12 _123 _1234 _12345_
, there would be four false starts before it found a match.

SQL Server by default uses the mdy
date format and so the below works:
SELECT convert(datetime, '07/23/2009', 111)
and this does not work:
SELECT convert(datetime, '23/07/2009', 111)
I myself have been struggling to come up with a single query that can handle both date formats: mdy
and dmy
.
However, you should be ok with the third date format - ymd
.

Here is a tidyverse
option that might work depending on the data, and some caveats on its usage:
library(tidyverse)
starting_df %>%
rownames_to_column() %>%
gather(variable, value, -rowname) %>%
spread(rowname, value)
rownames_to_column()
is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column()
and replace rowname
with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths
sample data would be:
smiths %>%
gather(variable, value, -subject) %>%
spread(subject, value)
Using the example starting_df
with the tidyverse
approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths
data will not give that warning because all columns except for subject
are doubles.
The earlier answer using as.data.frame(t())
will convert everything to a factor
if there are mixed column types unless stringsAsFactors = FALSE
is added,
whereas the tidyverse
option converts everything to a character by default if
there are mixed column types.
Git pull combines two actions -- fetching new commits from the remote repository in the tracked branches and then merging them into your current branch.
When you checked out a particular commit, you don't have a current branch, you only have HEAD pointing to the last commit you made. So git pull
doesn't have all its parameters specified. That's why it didn't work.
Based on your updated info, what you're trying to do is revert your remote repo. If you know the commit that introduced the bug, the easiest way to handle this is with git revert
which records a new commit which undoes the specified buggy commit:
$ git checkout master
$ git reflog #to find the SHA1 of buggy commit, say b12345
$ git revert b12345
$ git pull
$ git push
Since it's your server that you are wanting to change, I will assume that you don't need to rewrite history to hide the buggy commit.
If the bug was introduced in a merge commit, then this procedure will not work. See How-to-revert-a-faulty-merge.

In python you must always pass in at least one argument to class methods, the argument is self

I would say the csv
library is the only sensible option here, as it was built to cope with all csv use cases such as commas in a string, etc.
To output a list l
to a .csv file:
import csv
with open('some.csv', 'w', newline='') as f:
writer = csv.writer(f)
writer.writerow(l) # this will output l as a single row.
It is also possible to use writer.writerows(iterable)
to output multiple rows to csv.
This example is compatible with Python 3, as the other answer here used StringIO
which is Python 2.

To prevent problems with stale links (I have found MSDN blogs to disappear for no reason in the past), in essence for Windows 7 you need to download and install Remote Server Administration Tools (KB958830). After installing do the following steps:
Windows server editions should already be OK but if not you need to download and install the Active Directory Management Gateway Service. If any of these links should stop working, you should still be able search for the KB article or download names and find them.
The error Object expected
is raised because Jquery is not loaded. This happens because of browser security (usually IE) which does not allow you executing external javascript source code. You can correct this problem by:
OR
I prefer the first solution.
You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.
So if you want to use your code, you could do:
df = DataFrame(eval(data))
But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:
data = []
for row in result_set:
data.append({'value': row["tag_expression"], 'key': row["tag_name"]})
But probably even this is not needed, as depending on what is exactly in your result_set
you could probably:
DataFrame(result_set)

Two ways to run eclipse in clean mode.
1 ) In Eclipse.ini file
2 ) From Command prompt (cmd/command)
See Python's document on sharing global variables across modules:
The canonical way to share information across modules within a single program is to create a special module (often called config or cfg).
config.py:
x = 0 # Default value of the 'x' configuration setting
Import the config module in all modules of your application; the module then becomes available as a global name.
main.py:
import config print (config.x)
or
from config import x print (x)
In general, don’t use from modulename import *. Doing so clutters the importer’s namespace, and makes it much harder for linters to detect undefined names.
That would be the Enter key.
Probably the biggest problem of heap allocation versus stack allocation, is that heap allocation in the general case is an unbounded operation, and thus you can't use it where timing is an issue.
For other applications where timing isn't an issue, it may not matter as much, but if you heap allocate a lot, this will affect the execution speed. Always try to use the stack for short lived and often allocated memory (for instance in loops), and as long as possible - do heap allocation during application startup.
If you have a custom template and view you may exclude the field and use {{ modelform.instance.field }}
to get the value.
also you may prefer to use in the view:
form.fields['field_name'].widget = forms.HiddenInput()
but I'm not sure it will protect save method on post.
Hope it helps.
You can't do
LivingRoom.objects.create(user=instance)
because you have an __init__
method that does NOT take user
as argument.
You need something like
#signal function: if a user is created, add control livingroom to the user
def create_control_livingroom(sender, instance, created, **kwargs):
if created:
my_room = LivingRoom()
my_room.user = instance
Update
But, as bruno has already said it, Django's models.Model
subclass's initializer is best left alone, or should accept *args
and **kwargs
matching the model's meta fields.
So, following better principles, you should probably have something like
class LivingRoom(models.Model):
'''Living Room object'''
user = models.OneToOneField(User)
def __init__(self, *args, temp=65, **kwargs):
self.temp = temp
return super().__init__(*args, **kwargs)
Note - If you weren't using temp
as a keyword argument, e.g. LivingRoom(65)
, then you'll have to start doing that. LivingRoom(user=instance, temp=66)
or if you want the default (65), simply LivingRoom(user=instance)
would do.
cURL-less you can use in php5
$url = 'URL';
$data = array('field1' => 'value', 'field2' => 'value');
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
If you only need the first row from each group we can do with drop_duplicates
, Notice the function default method keep='first'
.
df.drop_duplicates('id')
Out[1027]:
id value
0 1 first
3 2 first
5 3 first
9 4 second
11 5 first
12 6 first
15 7 fourth
The very simple "catch all" solution is this:
System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
The solution from sebastian-castaldi is a bit more detailed.
I hope this helps someone. I use this bit of logic to verify if network shares are responsive before checking the individual paths. It should handle DNS names and IP addresses

The source of this error on my Apache 2.4 instance (using a Comodo wildcard certificate) was an incomplete path to the SHA-1 signed root certificate. There were multiple chains in the issued certificate, and the chain leading to a SHA-1 root certificate was missing an intermediate certificate. Modern browsers know how to handle this, but Java 7 doesn't handle it by default (although there are some convoluted ways to accomplish this in code). The result is error messages that look identical to the case of self-signed certificates:
Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at sun.security.provider.certpath.SunCertPathBuilder.engineBuild(SunCertPathBuilder.java:196)
at java.security.cert.CertPathBuilder.build(CertPathBuilder.java:268)
at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:380)
... 22 more
In this case, the "unable to find valid certification path to requested target" message is being produced due to the missing intermediate certificate. You can check which certificate is missing using SSL Labs test against the server. Once you find the appropriate certificate, download it and (if the server is under your control) add it to the certificate bundle. Alternatively, you can import the missing certificate locally. Accommodating this issue on the server is a more general solution to the problem.
You can try to run the main function from the outline side bar of eclipse.
You can use this code:
// Create an array that matches any country to its id (as String):
String[][] countriesId = new String[NUMBER_OF_COUNTRIES_SUPPORTED][];
// Initialize the array, where the first column will be the country's name (in uppercase) and the second column will be its id (as String):
countriesId[0] = new String[] {"US", String.valueOf(R.drawable.us)};
countriesId[1] = new String[] {"FR", String.valueOf(R.drawable.fr)};
// and so on...
// And after you get the variable "countryCode":
int i;
for(i = 0; i<countriesId.length; i++) {
if(countriesId[i][0].equals(countryCode))
break;
}
// Now "i" is the index of the country
img.setImageResource(Integer.parseInt(countriesId[i][1]));
Some of these fall into the category of general NLog (or logging) tips rather than strictly configuration suggestions.
Here are some general logging links from here at SO (you might have seen some or all of these already):
What's the point of a logging facade?
Why do loggers recommend using a logger per class?
Use the common pattern of naming your logger based on the class Logger logger = LogManager.GetCurrentClassLogger()
. This gives you a high degree of granularity in your loggers and gives you great flexibility in the configuration of the loggers (control globally, by namespace, by specific logger name, etc).
Use non-classname-based loggers where appropriate. Maybe you have one function for which you really want to control the logging separately. Maybe you have some cross-cutting logging concerns (performance logging).
If you don't use classname-based logging, consider naming your loggers in some kind of hierarchical structure (maybe by functional area) so that you can maintain greater flexibility in your configuration. For example, you might have a "database" functional area, an "analysis" FA, and a "ui" FA. Each of these might have sub-areas. So, you might request loggers like this:
Logger logger = LogManager.GetLogger("Database.Connect");
Logger logger = LogManager.GetLogger("Database.Query");
Logger logger = LogManager.GetLogger("Database.SQL");
Logger logger = LogManager.GetLogger("Analysis.Financial");
Logger logger = LogManager.GetLogger("Analysis.Personnel");
Logger logger = LogManager.GetLogger("Analysis.Inventory");
And so on. With hierarchical loggers, you can configure logging globally (the "*" or root logger), by FA (Database, Analysis, UI), or by subarea (Database.Connect, etc).
Loggers have many configuration options:
<logger name="Name.Space.Class1" minlevel="Debug" writeTo="f1" />
<logger name="Name.Space.Class1" levels="Debug,Error" writeTo="f1" />
<logger name="Name.Space.*" writeTo="f3,f4" />
<logger name="Name.Space.*" minlevel="Debug" maxlevel="Error" final="true" />
See the NLog help for more info on exactly what each of the options means. Probably the most notable items here are the ability to wildcard logger rules, the concept that multiple logger rules can "execute" for a single logging statement, and that a logger rule can be marked as "final" so subsequent rules will not execute for a given logging statement.
Use the GlobalDiagnosticContext, MappedDiagnosticContext, and NestedDiagnosticContext to add additional context to your output.
Use "variable" in your config file to simplify. For example, you might define variables for your layouts and then reference the variable in the target configuration rather than specify the layout directly.
<variable name="brief" value="${longdate} | ${level} | ${logger} | ${message}"/>
<variable name="verbose" value="${longdate} | ${machinename} | ${processid} | ${processname} | ${level} | ${logger} | ${message}"/>
<targets>
<target name="file" xsi:type="File" layout="${verbose}" fileName="${basedir}/${shortdate}.log" />
<target name="console" xsi:type="ColoredConsole" layout="${brief}" />
</targets>
Or, you could create a "custom" set of properties to add to a layout.
<variable name="mycontext" value="${gdc:item=appname} , ${mdc:item=threadprop}"/>
<variable name="fmt1withcontext" value="${longdate} | ${level} | ${logger} | [${mycontext}] |${message}"/>
<variable name="fmt2withcontext" value="${shortdate} | ${level} | ${logger} | [${mycontext}] |${message}"/>
Or, you can do stuff like create "day" or "month" layout renderers strictly via configuration:
<variable name="day" value="${date:format=dddd}"/>
<variable name="month" value="${date:format=MMMM}"/>
<variable name="fmt" value="${longdate} | ${level} | ${logger} | ${day} | ${month} | ${message}"/>
<targets>
<target name="console" xsi:type="ColoredConsole" layout="${fmt}" />
</targets>
You can also use layout renders to define your filename:
<variable name="day" value="${date:format=dddd}"/>
<targets>
<target name="file" xsi:type="File" layout="${verbose}" fileName="${basedir}/${day}.log" />
</targets>
If you roll your file daily, each file could be named "Monday.log", "Tuesday.log", etc.
Don't be afraid to write your own layout renderer. It is easy and allows you to add your own context information to the log file via configuration. For example, here is a layout renderer (based on NLog 1.x, not 2.0) that can add the Trace.CorrelationManager.ActivityId to the log:
[LayoutRenderer("ActivityId")]
class ActivityIdLayoutRenderer : LayoutRenderer
{
int estimatedSize = Guid.Empty.ToString().Length;
protected override void Append(StringBuilder builder, LogEventInfo logEvent)
{
builder.Append(Trace.CorrelationManager.ActivityId);
}
protected override int GetEstimatedBufferSize(LogEventInfo logEvent)
{
return estimatedSize;
}
}
Tell NLog where your NLog extensions (what assembly) like this:
<extensions>
<add assembly="MyNLogExtensions"/>
</extensions>
Use the custom layout renderer like this:
<variable name="fmt" value="${longdate} | ${ActivityId} | ${message}"/>
Use async targets:
<nlog>
<targets async="true">
<!-- all targets in this section will automatically be asynchronous -->
</targets>
</nlog>
And default target wrappers:
<nlog>
<targets>
<default-wrapper xsi:type="BufferingWrapper" bufferSize="100"/>
<target name="f1" xsi:type="File" fileName="f1.txt"/>
<target name="f2" xsi:type="File" fileName="f2.txt"/>
</targets>
<targets>
<default-wrapper xsi:type="AsyncWrapper">
<wrapper xsi:type="RetryingWrapper"/>
</default-wrapper>
<target name="n1" xsi:type="Network" address="tcp://localhost:4001"/>
<target name="n2" xsi:type="Network" address="tcp://localhost:4002"/>
<target name="n3" xsi:type="Network" address="tcp://localhost:4003"/>
</targets>
</nlog>
where appropriate. See the NLog docs for more info on those.
Tell NLog to watch and automatically reload the configuration if it changes:
<nlog autoReload="true" />
There are several configuration options to help with troubleshooting NLog
<nlog throwExceptions="true" />
<nlog internalLogFile="file.txt" />
<nlog internalLogLevel="Trace|Debug|Info|Warn|Error|Fatal" />
<nlog internalLogToConsole="false|true" />
<nlog internalLogToConsoleError="false|true" />
See NLog Help for more info.
NLog 2.0 adds LayoutRenderer wrappers that allow additional processing to be performed on the output of a layout renderer (such as trimming whitespace, uppercasing, lowercasing, etc).
Don't be afraid to wrap the logger if you want insulate your code from a hard dependency on NLog, but wrap correctly. There are examples of how to wrap in the NLog's github repository. Another reason to wrap might be that you want to automatically add specific context information to each logged message (by putting it into LogEventInfo.Context).
There are pros and cons to wrapping (or abstracting) NLog (or any other logging framework for that matter). With a little effort, you can find plenty of info here on SO presenting both sides.
If you are considering wrapping, consider using Common.Logging. It works pretty well and allows you to easily switch to another logging framework if you desire to do so. Also if you are considering wrapping, think about how you will handle the context objects (GDC, MDC, NDC). Common.Logging does not currently support an abstraction for them, but it is supposedly in the queue of capabilities to add.

For CSS inline style, this worked best for me.
This works perfectly:
$number = 13246;
echo sprintf( '%08d', $number );
There are many ways you can change the title, the main two, are like so:
Put a title tag in the HTML (e.g. <title>Hello</title>
), then in javascript:
let title_el = document.querySelector("title");
if(title_el)
title_el.innerHTML = "World";
The simplest of all is to actually use the method provided by the Document Object Model (DOM)
document.title = "Hello World";
The former method is generally what you would do to alter tags found in the body of the document. Using this method to modify meta-data tags like those found in the head (like title
) is questionable practice at best, is not idiomatic, not very good style to begin with, and might not even be portable. One thing you can be sure of, though, is that it will annoy other developers if they see title.innerHTML = ...
in code they are maintaining.
What you want to go with is the latter method. This property is provided in the DOM Specification specifically for the purpose of, as the name suggests, changing the title.
Note also that if you are working with XUL, you may want to check that the document has loaded before attempting to set or get the title, as otherwise you are invoking undefined behavior
(here be dragons), which is a scary concept in its own right. This may or may not happen via JavaScript, as the docs on the DOM do not necessarily pertain to JavaScript. But XUL is a whole 'nother beast, so I digress.
.innerHTML
Some good advice to keep in mind would be that using .innerHTML
is generally sloppy. Use appendChild
instead.
Although two cases where I still find .innerHTML
to be useful include inserting plain text into a small element...
label.innerHTML = "Hello World";
// as opposed to...
label.appendChild(document.createTextNode("Hello World"));
// example:
el.appendChild(function(){
let el = document.createElement("span");
el.className = "label";
el.innerHTML = label_text;
return el;
}());
...and clearing out a container...
container.innerHTML = "";
// as opposed to... umm... okay, I guess I'm rolling my own
[...container.childNodes].forEach(function(child){
container.removeChild(child);
});
Give the submit buttons for both forms different names and use PHP to check which button has submitted data.
Form one button - btn1 Form two button -btn2
PHP Code:
if($_POST['btn1']){
//Login
}elseif($_POST['btn2']){
//Register
}
As the Visual C# Program Manager linked above says, there are limited situations where the With statement is more efficient, the example he gives when it is being used as a shorthand to repeatedly access a complex expression.
Using an extension method and generics you can create something that is vaguely equivalent to a With statement, by adding something like this:
public static T With<T>(this T item, Action<T> action)
{
action(item);
return item;
}
Taking a simple example of how it could be used, using lambda syntax you can then use it to change something like this:
updateRoleFamily.RoleFamilyDescription = roleFamilyDescription;
updateRoleFamily.RoleFamilyCode = roleFamilyCode;
To this:
updateRoleFamily.With(rf =>
{
rf.RoleFamilyDescription = roleFamilyDescription;
rf.RoleFamilyCode = roleFamilyCode;
});
On an example like this, the only advantage is perhaps a nicer layout, but with a more complex reference and more properties, it could well give you more readable code.
IntelliJ IDEA seems to have reorganized the configurations panel. Now one should go to Editor -> Color Scheme and click on the gears icon to import the theme they want from external .jar

Is there a way to unmarshal the nested bar property and assign it directly to a struct property without creating a nested struct?
No, encoding/json cannot do the trick with ">some>deep>childnode" like encoding/xml can do. Nested structs is the way to go.

Recordsets have two important properties when looping through data, EOF (End-Of-File) and BOF (Beginning-Of-File). Recordsets are like tables and when you loop through one, you are literally moving from record to record in sequence. As you move through the records the EOF property is set to false but after you try and go past the last record, the EOF property becomes true. This works the same in reverse for the BOF property.
These properties let us know when we have reached the limits of a recordset.

This error message may also happen when the data contains NA
s.
In this case, the behaviour depends on the defaults (see documentation), and maybe all cases with NA
's in the columns mentioned in the variables are silently dropped. So it may be that a factor does indeed have several outcomes, but the factor only has one outcome when restricting to the cases without NA
's.
In this case, to fix the error, either change the model (remove the problematic factor from the formula), or change the data (i.e. complete the cases).
How about this, it will read each line to a variable and that can be used subsequently ! say myscript output is redirected to a file called myscript_output
awk '{while ( (getline var < "myscript_output") >0){print var;} close ("myscript_output");}'
This is a quick and simple add of a named tab to the current worksheet:
Sheets.Add.Name = "Tempo"
The AS
in this case is an optional keyword defined in ANSI SQL 92 to define a <<correlation name>
,commonly known as alias for a table.
<table reference> ::= <table name> [ [ AS ] <correlation name> [ <left paren> <derived column list> <right paren> ] ] | <derived table> [ AS ] <correlation name> [ <left paren> <derived column list> <right paren> ] | <joined table> <derived table> ::= <table subquery> <derived column list> ::= <column name list> <column name list> ::= <column name> [ { <comma> <column name> }... ] Syntax Rules 1) A <correlation name> immediately contained in a <table refer- ence> TR is exposed by TR. A <table name> immediately contained in a <table reference> TR is exposed by TR if and only if TR does not specify a <correlation name>.
It seems a best practice NOT to use the AS
keyword for table aliases as it is not supported by a number of commonly used databases.
Django-model-values (disclosure: author) provides an implementation of the NotEqual lookup, as in this answer. It also provides syntactic support for it:
from model_values import F
Model.objects.exclude(F.x != 5, a=True)
var timeArr = moment().format('x');
returns the Unix Millisecond Timestamp as per the format() documentation.
The answers here already are great, but don't necessarily work for custom ViewGroups. To get all custom Views to retain their state, you must override onSaveInstanceState()
and onRestoreInstanceState(Parcelable state)
in each class.
You also need to ensure they all have unique ids, whether they're inflated from xml or added programmatically.
What I came up with was remarkably like Kobor42's answer, but the error remained because I was adding the Views to a custom ViewGroup programmatically and not assigning unique ids.
The link shared by mato will work, but it means none of the individual Views manage their own state - the entire state is saved in the ViewGroup methods.
The problem is that when multiple of these ViewGroups are added to a layout, the ids of their elements from the xml are no longer unique (if its defined in xml). At runtime, you can call the static method View.generateViewId()
to get a unique id for a View. This is only available from API 17.
Here is my code from the ViewGroup (it is abstract, and mOriginalValue is a type variable):
public abstract class DetailRow<E> extends LinearLayout {
private static final String SUPER_INSTANCE_STATE = "saved_instance_state_parcelable";
private static final String STATE_VIEW_IDS = "state_view_ids";
private static final String STATE_ORIGINAL_VALUE = "state_original_value";
private E mOriginalValue;
private int[] mViewIds;
// ...
@Override
protected Parcelable onSaveInstanceState() {
// Create a bundle to put super parcelable in
Bundle bundle = new Bundle();
bundle.putParcelable(SUPER_INSTANCE_STATE, super.onSaveInstanceState());
// Use abstract method to put mOriginalValue in the bundle;
putValueInTheBundle(mOriginalValue, bundle, STATE_ORIGINAL_VALUE);
// Store mViewIds in the bundle - initialize if necessary.
if (mViewIds == null) {
// We need as many ids as child views
mViewIds = new int[getChildCount()];
for (int i = 0; i < mViewIds.length; i++) {
// generate a unique id for each view
mViewIds[i] = View.generateViewId();
// assign the id to the view at the same index
getChildAt(i).setId(mViewIds[i]);
}
}
bundle.putIntArray(STATE_VIEW_IDS, mViewIds);
// return the bundle
return bundle;
}
@Override
protected void onRestoreInstanceState(Parcelable state) {
// We know state is a Bundle:
Bundle bundle = (Bundle) state;
// Get mViewIds out of the bundle
mViewIds = bundle.getIntArray(STATE_VIEW_IDS);
// For each id, assign to the view of same index
if (mViewIds != null) {
for (int i = 0; i < mViewIds.length; i++) {
getChildAt(i).setId(mViewIds[i]);
}
}
// Get mOriginalValue out of the bundle
mOriginalValue = getValueBackOutOfTheBundle(bundle, STATE_ORIGINAL_VALUE);
// get super parcelable back out of the bundle and pass it to
// super.onRestoreInstanceState(Parcelable)
state = bundle.getParcelable(SUPER_INSTANCE_STATE);
super.onRestoreInstanceState(state);
}
}

In my case, when laravel generated the .env configuration file, laravel also generated two uncommented "DB_HOST" lines at line 11 and 12, delete the one that says "mysql" and uncomment (if yours it's commented) the other one (the one with the localhost ip 127.0.0.1) and it worked. (In my case).

A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =
:
HOME=c
An environment variable is a regular variable that has been marked for export to the environment.
export HOME
HOME=c
You can combine the assignment with the export
statement.

Arrays.fill works with single dimensional array, so to fill two dimensional array we can do below
for (int i = 0, len = arr.length; i < len; i++)
Arrays.fill(arr[i], 0);
I haven't seen this anywhere, either, but my instinct would be that this means that the IF
prevented the whole statement from executing.
Try to run the statement with a database where the IF
passes.
Also check if there are any triggers involved which might change the result.
[EDIT] When the standard says that this function should never return -1
, that doesn't enforce this. Java doesn't have pre and post conditions. A JDBC driver could return a random number and there was no way to stop it.
If it's important to know why this happens, run the statement against different database until you have tried all execution paths (i.e. one where the IF
returns false
and one where it returns true
).
If it's not that important, mark it off as a "clever trick" by a Microsoft engineer and remember how much you liked it when you feel like being clever yourself next time.

For those still having issues with Renderscript support library on x86 chipsets, please have a look at this post by the creator of the library.

Personally, I got around this in a slightly different way - I had a pivot table querying an SQL server source and I was using the timeline slicer to restrict the results to a date range - I then wanted to summarise the pivot results in another table.
I selected the 'source' pivot table and created a named range called 'SourcePivotData'.
Create your summary pivot tables using the named range as a source.
In the worksheet events for the source pivot table, I put the following code:
Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
'Update the address of the named range
ThisWorkbook.Names("SourcePivotData").RefersTo = "='" & Target.TableRange1.Worksheet.Name & "'!" & Target.TableRange1.AddressLocal
'Refresh any pivot tables that use this as a source
Dim pt As PivotTable
Application.DisplayAlerts = False
For Each pt In Sheet2.PivotTables
pt.PivotCache.Refresh
Next pt
Application.DisplayAlerts = True
End Sub
Works nicely for me! :)
It might help the solution given in another forum, Basically is: i.e.
Cols <- paste("A", 1:5, sep="")
DF <- read.table(textConnection(""), col.names = Cols,colClasses = "character")
> str(DF)
'data.frame': 0 obs. of 5 variables:
$ A1: chr
$ A2: chr
$ A3: chr
$ A4: chr
$ A5: chr
You can change the colClasses to fit your needs.

ConcurrentLinkedQueue is lock-free, LinkedBlockingQueue is not. Every time you invoke LinkedBlockingQueue.put() or LinkedBlockingQueue.take(), you need acquire the lock first. In other word, LinkedBlockingQueue has poor concurrency. If you care performance, try ConcurrentLinkedQueue + LockSupport.

Why not just use, toggleClass on click?
js:
$(this).toggleClass("up");
css:
button.up {
-webkit-transform: rotate(180deg);
-moz-transform: rotate(180deg);
-ms-transform: rotate(180deg);
-o-transform: rotate(180deg);
transform: rotate(180deg);
/* IE6–IE9 */
filter: progid:DXImageTransform.Microsoft.Matrix(M11=0.9914448613738104, M12=-0.13052619222005157,M21=0.13052619222005157, M22=0.9914448613738104, sizingMethod='auto expand');
zoom: 1;
}
you can also add this to the css:
button{
-webkit-transition: all 500ms ease-in-out;
-moz-transition: all 500ms ease-in-out;
-o-transition: all 500ms ease-in-out;
-ms-transition: all 500ms ease-in-out;
}
which will add the animation.
PS...
to answer your original question:
you said that it rotates but never stops. When using set timeout you need to make sure you have a condition that will not call settimeout or else it will run forever. So for your code:
<script type="text/javascript">
$(function() {
var $elie = $("#bkgimg");
rotate(0);
function rotate(degree) {
// For webkit browsers: e.g. Chrome
$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
// For Mozilla browser: e.g. Firefox
$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
/* add a condition here for the extremity */
if(degree < 180){
// Animate rotation with a recursive call
setTimeout(function() { rotate(++degree); },65);
}
}
});
</script>
With approach explained by EdChum above, the values in the list are shown as rows. To show the values of lists as columns in DataFrame instead, simply use transpose() as following:
table = [[1 , 2], [3, 4]]
df = pd.DataFrame(table)
df = df.transpose()
df.columns = ['Heading1', 'Heading2']
The output then is:
Heading1 Heading2
0 1 3
1 2 4
I wanted 2 way conversion, and I wanted to use Python 3 format() support to be most pythonic. Maybe try datasize library module? https://pypi.org/project/datasize/
$ pip install -qqq datasize
$ python
...
>>> from datasize import DataSize
>>> 'My new {:GB} SSD really only stores {:.2GiB} of data.'.format(DataSize('750GB'),DataSize(DataSize('750GB') * 0.8))
'My new 750GB SSD really only stores 558.79GiB of data.'

There's an automatic refresh-on-change tool for IE. It's called ReloadIt, and is available at http://reloadit.codeplex.com . Free.
You choose a URL that you'd like to auto-reload, and specify one or more directory paths to monitor for changes. Press F12 to start monitoring.
After you set it, minimize it. Then edit your content files. When you save any change, the page gets reloaded. like this:

How about this one?
"my test string \t\t with crazy stuff is cool ".replace(/\s{2,9999}|\t/g, ' ')
outputs "my test string with crazy stuff is cool "
This one gets rid of any tabs as well

As written in PEP8:
Comparisons to singletons like None should always be done with 'is' or 'is not', never the equality operators.
Also, beware of writing "if x" when you really mean "if x is not None" -- e.g. when testing whether a variable or argument that defaults to None was set to some other value. The other value might have a type (such as a container) that could be false in a boolean context!
You can access your array keys like so:
foreach ($array as $key => $value)
You can build it with list comprehension like this:
>>> dict((i, range(int(i), int(i) + 2)) for i in ['1', '2'])
{'1': [1, 2], '2': [2, 3]}
And for the second part of your question use defaultdict
>>> from collections import defaultdict
>>> s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
>>> d = defaultdict(list)
>>> for k, v in s:
d[k].append(v)
>>> d.items()
[('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])]
From http://docs.python-requests.org/en/latest/user/quickstart/
url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}
r = requests.post(url, data=json.dumps(payload), headers=headers)
You just need to create a dict with your headers (key: value pairs where the key is the name of the header and the value is, well, the value of the pair) and pass that dict to the headers parameter on the .get
or .post
method.
So more specific to your question:
headers = {'foobar': 'raboof'}
requests.get('http://himom.com', headers=headers)

It can be done very easily in one step. You don't have to touch AndroidManifest. Instead do the following:
Might be useful to some, simple one line to clear all local branches except master and develop
git branch | grep -v "master" | grep -v "develop" | xargs git branch -D

If you want to update Spyder in the root environment, then conda update spyder
works for me.
If you want to update Spyder for a virtual environment you have created (e.g., for a different version of Python), then conda update -n $ENV_NAME spyder
where $ENV_NAME
is your environment name.
EDIT: In case conda update spyder
isn't working, this post indicates you might need to run conda update anaconda
before updating spyder. Also note that you can specify an exact spyder version if you want.
the rdl file content:
<Visibility><Hidden>=Parameters!casetype.Value=300</Hidden></Visibility>
so the text box will hidden, if your expression is true.
I suspect you can adjust your approach a little and use something along the lines of the example here:
https://www.typescriptlang.org/docs/handbook/advanced-types.html#user-defined-type-guards
function isFish(pet: Fish | Bird): pet is Fish {
return (pet as Fish).swim !== undefined;
}
Sorry for necrobumping, but none of the provided answers did what I intuitively understood as "flattening a multidimensional array". Namely this case:
[
'a' => [
'b' => 'value',
]
]
all of the provided solutions would flatten it into just ['value']
, but that loses information about the key and the depth, plus if you have another 'b' key somewhere else, it will overwrite them.
I wanted to get a result like this:
[
'a_b' => 'value',
]
array_walk_recursive
doesn't pass the information about the key it's currently recursing, so I did it with just plain recursion:
function flatten($array, $prefix = '') {
$return = [];
foreach ($array as $key => $value) {
if (is_array($value)) {
$return = array_merge($return, flatten($value, $prefix . $key . '_'));
} else {
$return[$prefix . $key] = $value;
}
}
return $return;
}
Modify the $prefix and '_' separator to your liking.

You can fill it from XAML or from .cs. There are few ways to fill controls with data. It would be best for You to read more about WPF technology, it allows to do many things in many ways, depending on Your needs. It's more important to choose method based on Your project needs. You can start here. It's an easy article about creating combobox, and filling it with some data.
The easiest way, is to use function not alias. you can still call a function at any time from the cli. In bash, you can just add function name() { command } it loads the same as an alias.
function mkcd() { mkdir $1; cd $1 ;}
Not sure about other shells
To generate a shared library you need first to compile your C code with the -fPIC
(position independent code) flag.
gcc -c -fPIC hello.c -o hello.o
This will generate an object file (.o), now you take it and create the .so file:
gcc hello.o -shared -o libhello.so
EDIT: Suggestions from the comments:
You can use
gcc -shared -o libhello.so -fPIC hello.c
to do it in one step. – Jonathan Leffler
I also suggest to add -Wall
to get all warnings, and -g
to get debugging information, to your gcc
commands. – Basile Starynkevitch

You have to remember your computer can have more than one IP (actually it always does) - so which one are you after.
Similar answers already exist above, I added this one to explain how the following line of code works exactly:
ptr += sprintf(ptr, "%02X", buf[i])
It's quiet tricky and not easy to understand, I put the explanation in the comments below:
uint8 buf[] = {0, 1, 10, 11};
/* Allocate twice the number of bytes in the "buf" array because each byte would
* be converted to two hex characters, also add an extra space for the terminating
* null byte.
* [size] is the size of the buf array */
char output[(size * 2) + 1];
/* pointer to the first item (0 index) of the output array */
char *ptr = &output[0];
int i;
for (i = 0; i < size; i++) {
/* "sprintf" converts each byte in the "buf" array into a 2 hex string
* characters appended with a null byte, for example 10 => "0A\0".
*
* This string would then be added to the output array starting from the
* position pointed at by "ptr". For example if "ptr" is pointing at the 0
* index then "0A\0" would be written as output[0] = '0', output[1] = 'A' and
* output[2] = '\0'.
*
* "sprintf" returns the number of chars in its output excluding the null
* byte, in our case this would be 2. So we move the "ptr" location two
* steps ahead so that the next hex string would be written at the new
* location, overriding the null byte from the previous hex string.
*
* We don't need to add a terminating null byte because it's been already
* added for us from the last hex string. */
ptr += sprintf(ptr, "%02X", buf[i]);
}
printf("%s\n", output);
You can load HTML page partial, in your case is everything inside div#mytable.
setTimeout(function(){
$( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds
more information read this http://api.jquery.com/load/
<button id="refresh-btn">Refresh Table</button>
<script>
$(document).ready(function() {
function RefreshTable() {
$( "#mytable" ).load( "your-current-page.html #mytable" );
}
$("#refresh-btn").on("click", RefreshTable);
// OR CAN THIS WAY
//
// $("#refresh-btn").on("click", function() {
// $( "#mytable" ).load( "your-current-page.html #mytable" );
// });
});
</script>
I had the same issue. And I solved it by changing the remote branch's path from https://github.com/YourName/RepoName
to [email protected]:YourName/RepoName.git
in the repo's settings of the client app.
My issue was with different version of DevExpress.
Deleting all contents from bin and obj folders made my website run again...
Reference: https://www.devexpress.com/Support/Center/Question/Details/KA18674
You can quote the entire path as in windows or you can escape the spaces like in:
/foo\ folder\ with\ space/foo.sh -help
Both ways will work!
Here a 2.7-compatible version derived from the 3.0 version by @Vadim-Zin4uk:
Python 2
import time
for i in range(101): # for 0 to 100
s = str(i) + '%' # string for output
print '{0}\r'.format(s), # just print and flush
time.sleep(0.2)
For that matter, the 3.0 solution provided looks a little bloated. For example, the backspace method doesn't make use of the integer argument and could probably be done away with altogether.
Python 3
import time
for i in range(101): # for 0 to 100
s = str(i) + '%' # string for output
print('{0}\r'.format(s), end='') # just print and flush
time.sleep(0.2) # sleep for 200ms
Both have been tested and work.
You can solve this issue be adding max-width
:
#element {
width: 100vw;
height: 100vw;
max-width: 100%;
}
When you using CSS to make the wrapper full width using the code width: 100vw;
then you will notice a horizontal scroll in the page, and that happened because the padding
and margin
of html
and body
tags added to the wrapper size, so the solution is to add max-width: 100%
While it's ok to use inline styles, your purposes may better be served by including an external CSS file on the page. This way you could define a class of image (i.e. 'Thumbnail', 'Photo', 'Large', etc) and assign it a constant size. This will help when you end up with images requiring the same placement across multiple pages.
Like this:
In your header: <link type="text/css" rel="stylesheet" href="css/style.css" /> Your HTML: <img class="thumbnail" src="images/academia_vs_business.png" alt="" /> In css/style.css: img.thumbnail { width: 75px; height: 75px; }
If you'd like to use inline styles though, it's probably best to set the width and height using the style attribute for the sake of readability.
Give headercss position fixed.
.headercss {
width: 100%;
height: 320px;
background-color: #000000;
position: fixed;
top:0
}
Then give the content container a 320px padding-top, so it doesn't get behind the header.
Most fastest and easy way:
$('#myCheckbox').change(function(){
alert(this.checked);
});
$el[0].checked;
$el - is jquery element of selection.
Enjoy!
I got the same trouble, in mobile device with Microsoft's Edge browser. I can solve the problem with: aria-haspopup="true"
. It need to add to the div and the :hover
, :active
, :focus
for the other mobile browsers.
Example html:
<div class="left_bar" aria-haspopup="true">
CSS:
.left_bar:hover, .left_bar:focus, .left_bar:active{
left: 0%;
}

STACK:
QUEUE:
Visiting this thread after some period of inactivity, but given that I don't see a thorough answer, here's my two cents.
Breadth-first search will always find the shortest path in an unweighted graph. The graph may be cyclic or acyclic.
See below for pseudocode. This pseudocode assumes that you are using a queue to implement BFS. It also assumes you can mark vertices as visited, and that each vertex stores a distance parameter, which is initialized as infinity.
mark all vertices as unvisited
set the distance value of all vertices to infinity
set the distance value of the start vertex to 0
if the start vertex is the end vertex, return 0
push the start vertex on the queue
while(queue is not empty)
dequeue one vertex (we’ll call it x) off of the queue
if x is not marked as visited:
mark it as visited
for all of the unmarked children of x:
set their distance values to be the distance of x + 1
if the value of x is the value of the end vertex:
return the distance of x
otherwise enqueue it to the queue
if here: there is no path connecting the vertices
Note that this approach doesn't work for weighted graphs - for that, see Dijkstra's algorithm.
Thanks Kip, for those who may be looking to achieve the same using $(this) whilst iterating or associating within a function:
$("label[for="+$(this).attr("id")+"]").addClass( "orienSel" );
I looked for a while whilst working this project but couldn't find a good example so I hope this helps others who may be looking to resolve the same issue.
In the example above, my objective was to hide the radio inputs and style the labels to provide a slicker user experience (changing the orientation of the flowchart).
You can see an example here
If you like the example, here is the css:
.orientation { position: absolute; top: -9999px; left: -9999px;}
.orienlabel{background:#1a97d4 url('http://www.ifreight.solutions/process.html/images/icons/flowChart.png') no-repeat 2px 5px; background-size: 40px auto;color:#fff; width:50px;height:50px;display:inline-block; border-radius:50%;color:transparent;cursor:pointer;}
.orR{ background-position: 9px -57px;}
.orT{ background-position: 2px -120px;}
.orB{ background-position: 6px -177px;}
.orienSel {background-color:#323232;}
and the relevant part of the JavaScript:
function changeHandler() {
$(".orienSel").removeClass( "orienSel" );
if(this.checked) {
$("label[for="+$(this).attr("id")+"]").addClass( "orienSel" );
}
};
An alternate root to the original question, given the label follows the input, you could go with a pure css solution and avoid using JavaScript altogether...:
input[type=checkbox]:checked+label {}
I'd suggest doing something similar to:
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = parent.getElementsByClassName('sub');
if (sub[0].style.display == 'inline'){
sub[0].style.display = 'none';
}
else {
sub[0].style.display = 'inline';
}
}
}
document.getElementById('cat').onclick = function(){
show_sub(this.id);
};????
Though the above relies on the use of a class
rather than a name
attribute equal to sub
.
As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:
Uncaught TypeError: Object # has no method 'getElementsByName'.
One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName()
, albeit crudely:
function eBCN(elem,classN){
if (!elem || !classN){
return false;
}
else {
var children = elem.childNodes;
for (var i=0,len=children.length;i<len;i++){
if (children[i].nodeType == 1
&&
children[i].className == classN){
var sub = children[i];
}
}
return sub;
}
}
function show_sub(cat) {
if (!cat) {
return false;
}
else if (document.getElementById(cat)) {
var parent = document.getElementById(cat),
sub = eBCN(parent,'sub');
if (sub.style.display == 'inline'){
sub.style.display = 'none';
}
else {
sub.style.display = 'inline';
}
}
}
var D = document,
listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
listElems[i].onclick = function(){
show_sub(this.id);
};
}?

What's FAT?
FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.
The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.
What About VFAT?
Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.
When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.
An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.
You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.
FAT32
FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.
The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.
This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.
Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.
Note: This section of the quote/ article (1999) is out of date. Updated info quote below.
As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.
The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.
Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.
Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):
I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.
The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.
The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.
to load a KeyStore, you'll need to tell it the type of keystore it is (probably jceks), provide an inputstream, and a password. then, you can load it like so:
KeyStore ks = KeyStore.getInstance(TYPE_OF_KEYSTORE);
ks.load(new FileInputStream(PATH_TO_KEYSTORE), PASSWORD);
this can throw a KeyStoreException, so you can surround in a try block if you like, or re-throw. Keep in mind a keystore can contain multiple keys, so you'll need to look up your key with an alias, here's an example with a symmetric key:
SecretKeyEntry entry = (KeyStore.SecretKeyEntry)ks.getEntry(SOME_ALIAS,new KeyStore.PasswordProtection(SOME_PASSWORD));
SecretKey someKey = entry.getSecretKey();
LocationManager is a class that provides in-build methods to get last know location
STEP 1 :Create a LocationManager Object as below
LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
STEP 2 : Add Criteria
*Criteria is use for setting accuracy*
Criteria criteria = new Criteria();
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (currentapiVersion >= android.os.Build.VERSION_CODES.HONEYCOMB) {
criteria.setSpeedAccuracy(Criteria.ACCURACY_HIGH);
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(true);
criteria.setBearingRequired(true);
criteria.setSpeedRequired(true);
}
STEP 3 :GET Avaliable Provider
Threre are two types of provider GPS and network
String provider = locationManager.getBestProvider(criteria, true);
STEP 4: Get Last Know Location
Location location = locationManager.getLastKnownLocation(provider);
STEP 5: Get Latitude and Longitude
If location object is null then dont try to call below methods
getLatitude and getLongitude is methods which returns double values

The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND
command on another connection, but it apparently was "not opening [it] up in sync with the client side".
Well, the main reason would be there was no synchronisation whatsoever. Calling:
cs.send("SEND " + FILE)
cs.close()
would just place the data into a OS buffer; close
would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep
after close
might mitigate the problem, but this is not synchronisation.
The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK
, or better PORT 36250
to indicate where to connect). This would make sure the server is already listening.
The other thing is you must check the return values of send
to make sure how many bytes was taken from your buffer. Or use sendall
.
(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)
Your E
class doesn't have a member of type struct X
, you've just defined a nested struct X
in there (i.e. you've defined a new type).
Try:
#include <iostream>
class E
{
public:
struct X { int v; };
X x; // an instance of `struct X`
};
int main(){
E object;
object.x.v = 1;
return 0;
}
with()
is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.
Example:
User > hasMany > Post
$users = User::with('posts')->get();
foreach($users as $user){
$users->posts; // posts is already loaded and no additional DB query is run
}
has()
is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation')
that means you only want to get the models that have at least one related model in this relation.
Example:
User > hasMany > Post
$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection
whereHas()
works basically the same as has()
but allows you to specify additional filters for the related model to check.
Example:
User > hasMany > Post
$users = User::whereHas('posts', function($q){
$q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned
None of the listed solutions worked for me. Problem was some sort of conflicting state in local applicationhost.config file. Fix is easy, just delete one in your solution. For VS2015 it should be located in <path_to_your_solution>\Solution\.vs\config\
. When you launch Debug, VS will recreate that file based on settings in your project file.
I don't think any of these answers are quite right/optimal. NameValueCollection not only doesn't distinguish between null values and missing values, it's also case-insensitive with regards to it's keys. Thus, I think a full solution would be:
public static bool ContainsKey(this NameValueCollection @this, string key)
{
return @this.Get(key) != null
// I'm using Keys instead of AllKeys because AllKeys, being a mutable array,
// can get out-of-sync if mutated (it weirdly re-syncs when you modify the collection).
// I'm also not 100% sure that OrdinalIgnoreCase is the right comparer to use here.
// The MSDN docs only say that the "default" case-insensitive comparer is used
// but it could be current culture or invariant culture
|| @this.Keys.Cast<string>().Contains(key, StringComparer.OrdinalIgnoreCase);
}

InputStream in = u.openStream();
Then use it as any plain old input stream
What would be useful here would be a LIKE ANY
predicate as is available in PostgreSQL
SELECT *
FROM tbl
WHERE my_col LIKE ANY (ARRAY['%val1%', '%val2%', '%val3%', ...])
Unfortunately, that syntax is not available in Oracle. You can expand the quantified comparison predicate using OR
, however:
SELECT *
FROM tbl
WHERE my_col LIKE '%val1%' OR my_col LIKE '%val2%' OR my_col LIKE '%val3%', ...
Or alternatively, create a semi join using an EXISTS
predicate and an auxiliary array data structure (see this question for details):
SELECT *
FROM tbl t
WHERE EXISTS (
SELECT 1
-- Alternatively, store those values in a temp table:
FROM TABLE (sys.ora_mining_varchar2_nt('%val1%', '%val2%', '%val3%'/*, ...*/))
WHERE t.my_col LIKE column_value
)
For true full-text search, you might want to look at Oracle Text: http://www.oracle.com/technetwork/database/enterprise-edition/index-098492.html
To be short, use:
write-output "your text" | out-file -append -encoding utf8 "filename"
i had the same problem, my solution was apply the required attribute to all elements
<input type="checkbox" name="checkin_days[]" required="required" value="0" /><span class="w">S</span>
<input type="checkbox" name="checkin_days[]" required="required" value="1" /><span class="w">M</span>
<input type="checkbox" name="checkin_days[]" required="required" value="2" /><span class="w">T</span>
<input type="checkbox" name="checkin_days[]" required="required" value="3" /><span class="w">W</span>
<input type="checkbox" name="checkin_days[]" required="required" value="4" /><span class="w">T</span>
<input type="checkbox" name="checkin_days[]" required="required" value="5" /><span class="w">F</span>
<input type="checkbox" name="checkin_days[]" required="required" value="6" /><span class="w">S</span>
when the user check one of the elements i remove the required attribute from all elements:
var $checkedCheckboxes = $('#recurrent_checkin :checkbox[name="checkin_days[]"]:checked'),
$checkboxes = $('#recurrent_checkin :checkbox[name="checkin_days[]"]');
$checkboxes.click(function() {
if($checkedCheckboxes.length) {
$checkboxes.removeAttr('required');
} else {
$checkboxes.attr('required', 'required');
}
});
Correct ways in jQuery are -
$('#test').prop('scrollHeight')
OR$('#test')[0].scrollHeight
OR$('#test').get(0).scrollHeight
You may use the already-existing delegate Action
:
private void UpdateMethod()
{
if (InvokeRequired)
{
Invoke(new Action(UpdateMethod));
}
}
decoration: InputDecoration(
border:OutLineInputBorder(
borderSide:BorderSide.none
bordeRadius: BordeRadius.circular(20.0)
)
)
In my case I don't use the Android studio (I am using eclipse). I did the following step: Solved just by running the command
android-sdks/tools/bin$ ./sdkmanager --update
Which created a licenses
directory and added a file called android-sdk-license
inside it.
Then you can run (licenses
option is not available unless you did the step above)
android-sdks/tools/bin$ ./sdkmanager --licenses
and accept the license (however, in my case I didn't need to do that)
You have to create a derived table for the distinct columns and then query the count from that table:
SELECT COUNT(*)
FROM (SELECT DISTINCT column1,column2
FROM tablename
WHERE condition ) as dt
Here dt
is a derived table.
There are many methods to this, here are some of them:
Using the predefined str
method islower()
:
>>> c = 'a'
>>> c.islower()
True
Using the ord()
function to check whether the ASCII code of the letter is in the range of the ASCII codes of the lowercase characters:
>>> c = 'a'
>>> ord(c) in range(97, 123)
True
Checking if the letter is equal to it's lowercase form:
>>> c = 'a'
>>> c.lower() == c
True
Checking if the letter is in the list ascii_lowercase
of the string
module:
>>> from string import ascii_lowercase
>>> c = 'a'
>>> c in ascii_lowercase
True
But that may not be all, you can find your own ways if you don't like these ones: D.
Finally, let's start detecting:
d = str(input('enter a string : '))
lowers = [c for c in d if c.islower()]
# here i used islower() because it's the shortest and most-reliable
# one (being a predefined function), using this list comprehension
# is (probably) the most efficient way of doing this
is it possible to extend query results with literals like this?
Yes.

It's the same as adding any other external script or stylesheet. All you have to do is focus on giving the correct path and rel and type.
Note: When my favicon image was in the assets folder, it was not displaying the favicon. So I copied the image to the same folder as of my index.html and it worked perfectly as it should.
<head>
<link rel="shortcut icon" type="image/png/ico" href="/favicon.png" />
<title>SITE NAME</title>
</head>
It worked for me. Hope it works for you too.
Config is written to .npmrc
files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list
will allways list the active config.

The Dir function will return only the file portion of the full path. Currentdb.Name is used here, but it could be any full path string.

One more example:
If you have Column from A to D, and need to highlight the whole line (e.g. from A to D) if B is "Complete", then you can do it following:
"Custom formula is": =$B:$B="Completed"
Background Color: red
Range: A:D
Of course, you can change Range to A:T if you have more columns.
If B contains "Complete", use search as following:
"Custom formula is": =search("Completed",$B:$B)
Background Color: red
Range: A:D
Given the original example:
var objs = [
{ first_nom: 'Lazslo', last_nom: 'Jamf' },
{ first_nom: 'Pig', last_nom: 'Bodine' },
{ first_nom: 'Pirate', last_nom: 'Prentice' }
];
Sort by multiple fields:
objs.sort(function(left, right) {
var last_nom_order = left.last_nom.localeCompare(right.last_nom);
var first_nom_order = left.first_nom.localeCompare(right.first_nom);
return last_nom_order || first_nom_order;
});
Notes
a.localeCompare(b)
is universally supported and returns -1,0,1 if a<b
,a==b
,a>b
respectively.||
in the last line gives last_nom
priority over first_nom
.var age_order = left.age - right.age;
return -last_nom_order || -first_nom_order || -age_order;
You are correct, this is indeed a way to initialize member variables. I'm not sure that there's much benefit to this, other than clearly expressing that it's an initialization. Having a "bar=num" inside the code could get moved around, deleted, or misinterpreted much more easily.
You can also use common table expressions to store temporary datasets. They are more elegant and adhoc friendly:
WITH userData (name, oldlocation)
AS
(
SELECT name, location
FROM myTable INNER JOIN
otherTable ON ...
WHERE age>30
)
SELECT *
FROM userData -- you can also reuse the recordset in subqueries and joins
Older MySQL versions this is enough:
SELECT
`userName`,
`carPrice`
FROM `users`
LEFT JOIN (SELECT * FROM `cars` ORDER BY `carPrice`) as `cars`
ON cars.belongsToUser=users.id
WHERE `id`='4'
Nowdays, if you use MariaDB the subquery should be limited.
SELECT
`userName`,
`carPrice`
FROM `users`
LEFT JOIN (SELECT * FROM `cars` ORDER BY `carPrice` LIMIT 18446744073709551615) as `cars`
ON cars.belongsToUser=users.id
WHERE `id`='4'

In unbuffered Input/Output(FileWriter, FileReader) read or write request is handled directly by the underlying OS. https://hajsoftutorial.com/java/wp-content/uploads/2018/04/Unbuffered.gif
This can make a program much less efficient, since each such request often triggers disk access, network activity, or some other operation that is relatively expensive. To reduce this kind of overhead, the Java platform implements buffered I/O streams. The BufferedReader and BufferedWriter classes provide internal character buffers. Text that’s written to a buffered writer is stored in the internal buffer and only written to the underlying writer when the buffer fills up or is flushed. https://hajsoftutorial.com/java/wp-content/uploads/2018/04/bufferedoutput.gif
In most cases, List<T>
is more useful. LinkedList<T>
will have less cost when adding/removing items in the middle of the list, whereas List<T>
can only cheaply add/remove at the end of the list.
LinkedList<T>
is only at it's most efficient if you are accessing sequential data (either forwards or backwards) - random access is relatively expensive since it must walk the chain each time (hence why it doesn't have an indexer). However, because a List<T>
is essentially just an array (with a wrapper) random access is fine.
List<T>
also offers a lot of support methods - Find
, ToArray
, etc; however, these are also available for LinkedList<T>
with .NET 3.5/C# 3.0 via extension methods - so that is less of a factor.
Scope Identity
: Identity of last record added within the stored procedure being executed.
@@Identity
: Identity of last record added within the query batch, or as a result of the query e.g. a procedure that performs an insert, the then fires a trigger that then inserts a record will return the identity of the inserted record from the trigger.
IdentCurrent
: The last identity allocated for the table.
The same way how an int
can be positive or negative. There is no difference. Actually on many platforms unqualified char
is signed.
Keep in mind that with pointers to struct you'd have to dereference the variable and not compare it with a pointer to empty struct:
session := &Session{}
if (Session{}) == *session {
fmt.Println("session is empty")
}
Check this playground.
Also here you can see that a struct holding a property which is a slice of pointers cannot be compared the same way...
use min-height
instead of height
You can use the instanceof
operator for this. From MDN:
The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototype chain of an object.
If you don't know what prototypes and prototype chains are I highly recommend looking it up. Also here is a JS (TS works similar in this respect) example which might clarify the concept:
class Animal {_x000D_
name;_x000D_
_x000D_
constructor(name) {_x000D_
this.name = name;_x000D_
}_x000D_
}_x000D_
_x000D_
const animal = new Animal('fluffy');_x000D_
_x000D_
// true because Animal in on the prototype chain of animal_x000D_
console.log(animal instanceof Animal); // true_x000D_
// Proof that Animal is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(animal) === Animal.prototype); // true_x000D_
_x000D_
// true because Object in on the prototype chain of animal_x000D_
console.log(animal instanceof Object); _x000D_
// Proof that Object is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(Animal.prototype) === Object.prototype); // true_x000D_
_x000D_
console.log(animal instanceof Function); // false, Function not on prototype chain_x000D_
_x000D_
_x000D_
The prototype chain in this example is:
animal > Animal.prototype > Object.prototype
As said in documentation here
Raised buttons have a minimum size of 88.0 by 36.0 which can be overidden with ButtonTheme.
You can do it like that
ButtonTheme(
minWidth: 200.0,
height: 100.0,
child: RaisedButton(
onPressed: () {},
child: Text("test"),
),
);
Here's some code that uses ctypes (only tested on Linux):
from ctypes import *
libc = CDLL("libc.so.6")
# struct timespec {
# time_t tv_sec; /* seconds */
# long tv_nsec; /* nanoseconds */
# };
# int futimens(int fd, const struct timespec times[2]);
class c_timespec(Structure):
_fields_ = [('tv_sec', c_long), ('tv_nsec', c_long)]
class c_utimbuf(Structure):
_fields_ = [('atime', c_timespec), ('mtime', c_timespec)]
utimens = CFUNCTYPE(c_int, c_char_p, POINTER(c_utimbuf))
futimens = CFUNCTYPE(c_int, c_char_p, POINTER(c_utimbuf))
# from /usr/include/i386-linux-gnu/bits/stat.h
UTIME_NOW = ((1l << 30) - 1l)
UTIME_OMIT = ((1l << 30) - 2l)
now = c_timespec(0,UTIME_NOW)
omit = c_timespec(0,UTIME_OMIT)
# wrappers
def update_atime(fileno):
assert(isinstance(fileno, int))
libc.futimens(fileno, byref(c_utimbuf(now, omit)))
def update_mtime(fileno):
assert(isinstance(fileno, int))
libc.futimens(fileno, byref(c_utimbuf(omit, now)))
# usage example:
#
# f = open("/tmp/test")
# update_mtime(f.fileno())
By the way. whenever my forms call the formclosed or form closing event I close the applciation with a this.Hide() function. Does that affect how my application is behaving now?
In short, yes. The entire application will end when the main form (the form started via Application.Run
in the Main
method) is closed (not hidden).
If your entire application should always fully terminate whenever your main form is closed then you should just remove that form closed handler. By not canceling that event and just letting them form close when the user closes it you will get your desired behavior. As for all of the other forms, if you don't intend to show that same instance of the form again you just just let them close, rather than preventing closure and hiding them. If you are showing them again, then hiding them may be fine.
If you want to be able to have the user click the "x" for your main form, but have another form stay open and, in effect, become the "new" main form, then it's a bit more complicated. In such a case you will need to just hide your main form rather than closing it, but you'll need to add in some sort of mechanism that will actually close the main form when you really do want your app to end. If this is the situation that you're in then you'll need to add more details to your question describing what types of applications should and should not actually end the program.
Old question, but if you want to do locale-aware sorting without setting locale.LC_ALL
you can do so by using the PyICU library as suggested by this answer:
import icu # PyICU
def sorted_strings(strings, locale=None):
if locale is None:
return sorted(strings)
collator = icu.Collator.createInstance(icu.Locale(locale))
return sorted(strings, key=collator.getSortKey)
Then call with e.g.:
new_list = sorted_strings(list_of_strings, "de_DE.utf8")
This worked for me without installing any locales or changing other system settings.
(This was already suggested in a comment above, but I wanted to give it more prominence, because I missed it myself at first.)
You would write a comparator class, for example:
struct CompareAge {
bool operator()(Person const & p1, Person const & p2) {
// return "true" if "p1" is ordered before "p2", for example:
return p1.age < p2.age;
}
};
and use that as the comparator argument:
priority_queue<Person, vector<Person>, CompareAge>
Using greater
gives the opposite ordering to the default less
, meaning that the queue will give you the lowest value rather than the highest.
Have created a small .swf
which redirects. If the browser is flash enabled it will redirect.
package com.play48.modules.standalone.util;

}
}
First, I try without a space, rtrim($arraynama, ",");
and get an error result.
Then I add a space and get a good result:
$newarraynama = rtrim($arraynama, ", ");
you can use str.isdigit() method or str.isnumeric() method
If you define words as "sequences of characters delimited by space"... Use strrpos()
to find the last space in the string, shorten to that position, trim the result.
From Charles' instructions, after testing my proposed understanding would be as follows:
# For the next commit
$ git add . # Add only files created/modified to the index and not those deleted
$ git add -u # Add only files deleted/modified to the index and not those created
$ git add -A # Do both operations at once, add to all files to the index
This blog post might also be helpful to understand in what situation those commands may be applied: Removing Deleted Files from your Git Working Directory.
Another idea:
Place all your parameters in a properties file (one parameter = one property in this file), then in your main method, load this file (using Properties.load(*fileInputStream*)
).
So if you want to modify one argument, you will just need to edit your args.properties file, and launch your application without more steps to do...
Of course, this is only for development purposes, but can be really helpfull if you have to change your arguments often...
More of an addendum. I did repro the experiment using the latest Java 8 JVM from IBM:
java version "1.8.0_191"
Java(TM) 2 Runtime Environment, Standard Edition (IBM build 1.8.0_191-b12 26_Oct_2018_18_45 Mac OS X x64(SR5 FP25))
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
And this shows very similar results:
0.374653912 s
n = 119860736
0.447778698 s
n = 119860736
(second results using 2 * i * i).
Interestingly enough, when running on the same machine, but using Oracle Java:
Java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
results are on average a bit slower:
0.414331815 s
n = 119860736
0.491430656 s
n = 119860736
Long story short: even the minor version number of HotSpot matter here, as subtle differences within the JIT implementation can have notable effects.
The author appears to have taken a freemium approach to the font library and provides Black Tie to give different weights to the Font-Awesome library.
The code snippet:
spyOn(myOtherService, "makeRemoteCallReturningPromise").and.callFake(function() {
var deferred = $q.defer();
deferred.resolve('Remote call result');
return deferred.promise;
});
Can be written in a more concise form:
spyOn(myOtherService, "makeRemoteCallReturningPromise").and.returnValue(function() {
return $q.resolve('Remote call result');
});
You could use a PowerShell command. Stick this in your batch script and it'll create a shortcut to %~f0
in %userprofile%\Start Menu\Programs\Startup
:
powershell "$s=(New-Object -COM WScript.Shell).CreateShortcut('%userprofile%\Start Menu\Programs\Startup\%~n0.lnk');$s.TargetPath='%~f0';$s.Save()"
If you prefer not to use PowerShell, you could use mklink
to make a symbolic link. Syntax:
mklink saveShortcutAs targetOfShortcut
See mklink /?
in a console window for full syntax, and this web page for further information.
In your batch script, do:
mklink "%userprofile%\Start Menu\Programs\Startup\%~nx0" "%~f0"
The shortcut created isn't a traditional .lnk file, but it should work the same nevertheless. Be advised that this will only work if the .bat file is run from the same drive as your startup folder. Also, apparently admin rights are required to create symbolic links.
If you have downloaded the latest Version 4.3.4 then just follow these steps.

I don't believe Windows (as opposed to .NET) provides a direct way to get that.
The only way I know of is to enumerate all the top level windows with EnumWindows()
and then find what process each belongs to GetWindowThreadProcessID()
. This sounds indirect and inefficient, but it's not as bad as you might expect -- in a typical case, you might have a dozen top level windows to walk through...
I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:
$(".bgHeaderH2").text();
The best and most accurate way to think of pass
is as a way to explicitly tell the interpreter to do nothing. In the same way the following code:
def foo(x,y):
return x+y
means "if I call the function foo(x, y), sum the two numbers the labels x and y represent and hand back the result",
def bar():
pass
means "If I call the function bar(), do absolutely nothing."
The other answers are quite correct, but it's also useful for a few things that don't involve place-holding.
For example, in a bit of code I worked on just recently, it was necessary to divide two variables, and it was possible for the divisor to be zero.
c = a / b
will, obviously, produce a ZeroDivisionError if b is zero. In this particular situation, leaving c as zero was the desired behavior in the case that b was zero, so I used the following code:
try:
c = a / b
except ZeroDivisionError:
pass
Another, less standard usage is as a handy place to put a breakpoint for your debugger. For example, I wanted a bit of code to break into the debugger on the 20th iteration of a for... in statement. So:
for t in range(25):
do_a_thing(t)
if t == 20:
pass
with the breakpoint on pass.
Ive had the same error just come up which aligned suspiciously with the latest round of Microsoft updates (09/02/2016). I found that SSMS connected without issue while my ASP.NET application returned the "timeout period elapsed while attempting to consume the pre-login handshake acknowledgement" error
The solution for me was to add a connection timeout of 30 seconds into the connection string eg:
ConnectionString="Data Source=xyz;Initial Catalog=xyz;Integrated Security=True;Connection Timeout=30;"
In my situation the only affected connection was one that was using integrated Security and I was impersonating a user before connecting, other connections to the same server using SQL Authentication worked fine!
2 test systems (separate clients and Sql servers) were affected at the same time leading me to suspect a microsoft update!
In my case, it was due to an IP address that Apache is listening to. Previously I have set it to 192.168.10.6 and recently Apache service is not running. I noticed that due to My laptop wifi changed recently and new IP is different. After fixing the wifi IP to laptop previous IP, Apache service is running again without any error.
Also if you don't want to change wifi IP then remove/comment that hardcode IP in httpd.conf file to resolve conflict.
Another solution is to use a shortcut file to cmd.exe instead of a batch file.
Edit the shortcut's start in property to %~dp0.
You achieve the same thing, except it has the Cmd icon (and you can change this).
Some people don't like clicking on batch files without knowing what's in them, and some corporate network drives have a ban on .bat files...
If you are doing it in eclipse, there are a few quick notes that if you are hovering your mouse over a class in your script, it will show a focus dialogue that says hit f2 for focus.
for computer apps, use ImageIcon. and for the path say,
ImageIcon thisImage = new ImageIcon("images/youpic.png");
specify the folder( images) then seperate with / and add the name of the pic file.
I hope this is helpful. If someone else posted it, I didn't read through. So...yea.. thought reinforcement.
I had this problem when trying to initialize log4net. I decided to just make a static constructor for the Global.asax

}
This worked for me. Go to Project->Propertied->Target Frawork->Change frame work like 3.5 to 4.0
I want to share an example which made a lot sense to me when I was learning:
This is just an example which does not include the virtual method or the base class. Just to give a hint regarding the main idea.
Let's say there is a Vehicle washing machine and it has a function called as "Wash" and accepts Car as a type.
Gets the Car input and washes the Car.
public void Wash(Car anyCar){
//wash the car
}
Let's overload Wash() function
Overloading:
public void Wash(Truck anyTruck){
//wash the Truck
}
Wash function was only washing a Car before, but now its overloaded to wash a Truck as well.
Let's override Wash() function
Overriding:
public override void Wash(Car anyCar){
//check if the car has already cleaned
if(anyCar.Clean){
//wax the car
}
else{
//wash the car
//dry the car
//wax the car
}
}
Wash function now has a condition to check if the Car is already clean and not need to be washed again.
If the Car is clean, then just wax it.
If not clean, then first wash the car, then dry it and then wax it
.
So the functionality has been overridden by adding a new functionality or do something totally different.

You can move your proxy authentication and ssl staff to soap handler

It use UrlConnection, you can use any library you want in handler. Have fun!
To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100
in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application.
If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.
jQuery.fn
is defined shorthand for jQuery.prototype
. From the source code:
jQuery.fn = jQuery.prototype = {
// ...
}
That means jQuery.fn.jquery
is an alias for jQuery.prototype.jquery
, which returns the current jQuery version. Again from the source code:
// The current version of jQuery being used
jquery: "@VERSION",
This is how I did it.

There are two options here. First, you can store the path unquoted and just quote it later:
set MyPath=C:\Program Files\Foo
"%MyPath%\foo with spaces.exe" something
Another option you could use is a subroutine which alles for un-quoting strings (but in this case it's actually not a very good idea since you're adding quotes, stripping them away and re-adding them again without benefit):
set MyPath="C:\Program Files\Foo"
call :foo %MyPath%
goto :eof
:foo
"%~1\foo.exe"
goto :eof
The %~1
removes quotation marks around the argument. This comes in handy when passing folder names around quoted but, as said before, in this particular case it's not the best idea :-)
I don't think that they are standardised macros. There are standardised functions for floating point already, fmax
and fmin
(and fmaxf
for floats, and fmaxl
for long doubles).
You can implement them as macros as long as you are aware of the issues of side-effects/double-evaluation.
#define MAX(a,b) ((a) > (b) ? a : b)
#define MIN(a,b) ((a) < (b) ? a : b)
In most cases, you can leave it to the compiler to determine what you're trying to do and optimise it as best it can. While this causes problems when used like MAX(i++, j++)
, I doubt there is ever much need in checking the maximum of incremented values in one go. Increment first, then check.

This is easier:
location.href = 'http://address.com';
Or
location.replace('http://address.com'); // <-- No history saved.
Where are you allocating memory for your buffer
? The line where you invoke bzero
invokes undefined behavior since buffer does not point to any valid region of memory.
char *buffer = new char[ BUFFER_SIZE ];
// do processing
// don't forget to release
delete[] buffer;
imports
are used to import supporting modules like FormsModule, RouterModule, CommonModule, or any other custom-made feature module.
declarations
are used to declare components, directives, pipes that belong to the current module. Everyone inside declarations knows each other. For example, if we have a component, say UsernameComponent, which displays a list of the usernames and we also have a pipe, say toupperPipe, which transforms a string to an uppercase letter string. Now If we want to show usernames in uppercase letters in our UsernameComponent then we can use the toupperPipe which we had created before but the question is how UsernameComponent knows that the toupperPipe exists and how it can access and use that. Here come the declarations, we can declare UsernameComponent and toupperPipe.
Providers
are used for injecting the services required by components, directives, pipes in the module.
I figured out what the issue was : missing quotes in the testEcho() parameter. This is how I got the call to work:
myWebView.loadUrl("javascript:testEcho('Hello World!')");
For this purpose, you can create your own function. For example:
$ echo 'mkfile() { mkdir -p "$(dirname "$1")" && touch "$1" ; }' >> ~/.bashrc
$ source ~/.bashrc
$ mkfile ./fldr1/fldr2/file.txt
Explanation:
~/.bashrc
file using the echo
command-p
flag is for creating the nested folders, such as fldr2
~/.bashrc
file with the source
commandmkfile
function to create the file
