I don't think we can compare them side by side like who is better. That won't be a fair comparison simply because they are solving two different problems. Their requirements are different. It will be like comparing apples to oranges. They are different.
HTTP is a request-response protocol. The client (browser) wants something, the server gives it. That is. If the data client wants is big, the server might send streaming data to void unwanted buffer problems. Here the main requirement or problem is how to make the request from clients and how to response the resources(hypertext) they request. That is where HTTP shine.
In HTTP, only client requests. The server only responds.
WebSocket is not a request-response protocol where only the client can request. It is a socket(very similar to TCP socket). Mean once the connection is open, either side can send data until the underlining TCP connection is closed. It is just like a normal socket. The only difference with TCP socket is WebSocket can be used on the web. On the web, we have many restrictions on a normal socket. Most firewalls will block other ports than 80 and 433 that HTTP used. Proxies and intermediaries will be problematic as well. So to make the protocol easier to deploy to existing infrastructures WebSocket use HTTP handshake to upgrade. That means when the first time connection is going to open, the client sent an HTTP request to tell the server saying "That is not HTTP request, please upgrade to WebSocket protocol".
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Key: x3JJHMbDL1EzLkh9GBhXDw==
Sec-WebSocket-Protocol: chat, superchat
Sec-WebSocket-Version: 13
Once the server understands the request and upgraded to WebSocket protocol, none of the HTTP protocols applied anymore.
So my answer is Neither one is better than each other. They are completely different.
Well, we can make everything under the name called HTTP as well. But shall we? If they are two different things, I will prefer two different names. So do Hickson and Michael Carter .
in my test.
close
will send fin packet and destroy fd immediately when socket is not shared with other processes
shutdown
SHUT_RD, process can still recv data from the socket, but recv
will return 0 if TCP buffer is empty.After peer send more data, recv
will return data again.
shutdown
SHUT_WR will send fin packet to indicate the Further sends are disallowed. the peer can recv data but it will recv 0 if its TCP buffer is empty
shutdown
SHUT_RDWR (equal to use both SHUT_RD and SHUT_WR) will send rst packet if peer send more data.
I think you're looking for this:
elements = [10, 11, 12, 13, 14, 15]
indices = (1,1,2,1,5)
result_list = [elements[i] for i in indices]
For strings, forget about using WHENCE: use f.seek(0) to position at beginning of file and f.seek(len(f)+1) to position at the end of file. Use open(file, "r+") to read/write anywhere in a file. If you use "a+" you'll only be able to write (append) at the end of the file regardless of where you position the cursor.
You can easily obtain Right() and Left() functions starting from the Rbase package:
right function
right = function (string, char) {
substr(string,nchar(string)-(char-1),nchar(string))
}
left function
left = function (string,char) {
substr(string,1,char)
}
you can use those two custom-functions exactly as left() and right() in excel. Hope you will find it useful
I found that there was a syntax error in the related module and it wasn't compiling - the compiler didn't tell me that though. Just gave me the error regarding the app.config stuff. VS2010. Once I had fixed the syntax error, all was good.
I had similar problem, when I was using public Wifi, which didn't have password. Switching the internet connection to a secure connection did solve the problem.
Here's an example of the ImageCodecInfo suggestion (in VB):
Imports System.Drawing.Imaging
...
Dim ofd as new OpenFileDialog()
ofd.Filter = ""
Dim codecs As ImageCodecInfo() = ImageCodecInfo.GetImageEncoders()
Dim sep As String = String.Empty
For Each c As ImageCodecInfo In codecs
Dim codecName As String = c.CodecName.Substring(8).Replace("Codec", "Files").Trim()
ofd.Filter = String.Format("{0}{1}{2} ({3})|{3}", ofd.Filter, sep, codecName, c.FilenameExtension)
sep = "|"
Next
ofd.Filter = String.Format("{0}{1}{2} ({3})|{3}", ofd.Filter, sep, "All Files", "*.*")
And it looks like this:
Apparently, org.json.simple.JSONArray
implements a raw Iterator. This means that each element is considered to be an Object
. You can try to cast:
for(Object o: arr){
if ( o instanceof JSONObject ) {
parse((JSONObject)o);
}
}
This is how things were done back in Java 1.4 and earlier.

Almost everything in EC2 is multi-tenant. What the network performance indicates is what priority you will have compared with other instances sharing the same infrastructure.
If you need a guaranteed level of bandwidth, then EC2 will likely not work well for you.
Yes, you can disable it using html.
Just add oncontextmenu="return false;"
on your body or element.
It is very simple and just uses valid HTML, no jQuery or JS.
What exactly are the rules for requesting retransmission of lost data?
The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.
Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ
are detailed in the RFC 3366.
At what time frequency are the retransmission requests performed?
The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)
The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.
Is there an upper bound on the number?
Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.
Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?
The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)
tl;dr;
mylist.clear() # Added in Python 3.3
del mylist[:]
are probably the best ways to do this. The rest of this answer tries to explain why some of your other efforts didn't work.
cpython at least works on reference counting to determine when objects will be deleted. Here you have multiple references to the same objects. a
refers to the same object that c[0]
references. When you loop over c
(for i in c:
), at some point i
also refers to that same object. the del
keyword removes a single reference, so:
for i in c:
del i
creates a reference to an object in c
and then deletes that reference -- but the object still has other references (one stored in c
for example) so it will persist.
In the same way:
def kill(self):
del self
only deletes a reference to the object in that method. One way to remove all the references from a list is to use slice assignment:
mylist = list(range(10000))
mylist[:] = []
print(mylist)
Apparently you can also delete the slice to remove objects in place:
del mylist[:] #This will implicitly call the `__delslice__` or `__delitem__` method.
This will remove all the references from mylist
and also remove the references from anything that refers to mylist
. Compared that to simply deleting the list -- e.g.
mylist = list(range(10000))
b = mylist
del mylist
#here we didn't get all the references to the objects we created ...
print(b) #[0, 1, 2, 3, 4, ...]
Finally, more recent python revisions have added a clear
method which does the same thing that del mylist[:]
does.
mylist = [1, 2, 3]
mylist.clear()
print(mylist)
That is called a shebang, it tells the shell what program to interpret the script with, when executed.
In your example, the script is to be interpreted and run by the bash shell.
Some other example shebangs are:
(From Wikipedia)
#!/bin/sh — Execute the file using sh, the Bourne shell, or a compatible shell
#!/bin/csh — Execute the file using csh, the C shell, or a compatible shell
#!/usr/bin/perl -T — Execute using Perl with the option for taint checks
#!/usr/bin/php — Execute the file using the PHP command line interpreter
#!/usr/bin/python -O — Execute using Python with optimizations to code
#!/usr/bin/ruby — Execute using Ruby
and a few additional ones I can think off the top of my head, such as:
#!/bin/ksh
#!/bin/awk
#!/bin/expect
In a script with the bash shebang, for example, you would write your code with bash syntax; whereas in a script with expect shebang, you would code it in expect syntax, and so on.
Response to updated portion:
It depends on what /bin/sh
actually points to on your system. Often it is just a symlink to /bin/bash
. Sometimes portable scripts are written with #!/bin/sh
just to signify that it's a shell script, but it uses whichever shell is referred to by /bin/sh
on that particular system (maybe it points to /bin/bash
, /bin/ksh
or /bin/zsh
)
The cause of errors such as "Invalid application of sizeof to incomplete type with a struct ... " is always lack of an include statement. Try to find the right library to include.
That's simple, in Java
your_component.setRotation(15);
or
your_component.setRotation(295.18f);
in XML
<Button android:rotation="15" />
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:MM");
simpleDateFormat.format(fajr_prayertime);
Most simple, without caring about delegates
if(textBox1.InvokeRequired == true)
textBox1.Invoke((MethodInvoker)delegate { textBox1.Text = "Invoke was needed";});
else
textBox1.Text = "Invoke was NOT needed";
The easiest solution to this is to use rgba
as the color: border-color: rgba(0,0,0,0);
That is fully transparent border color.
The answer, in a few words
In your example, itsProblem
is a local variable.
Your must use self
to set and get instance variables. You can set it in the __init__
method. Then your code would be:
class Example(object):
def __init__(self):
self.itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
But if you want a true class variable, then use the class name directly:
class Example(object):
itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
print (Example.itsProblem)
But be careful with this one, as theExample.itsProblem
is automatically set to be equal to Example.itsProblem
, but is not the same variable at all and can be changed independently.
Some explanations
In Python, variables can be created dynamically. Therefore, you can do the following:
class Example(object):
pass
Example.itsProblem = "problem"
e = Example()
e.itsSecondProblem = "problem"
print Example.itsProblem == e.itsSecondProblem
prints
True
Therefore, that's exactly what you do with the previous examples.
Indeed, in Python we use self
as this
, but it's a bit more than that. self
is the the first argument to any object method because the first argument is always the object reference. This is automatic, whether you call it self
or not.
Which means you can do:
class Example(object):
def __init__(self):
self.itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
or:
class Example(object):
def __init__(my_super_self):
my_super_self.itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
It's exactly the same. The first argument of ANY object method is the current object, we only call it self
as a convention. And you add just a variable to this object, the same way you would do it from outside.
Now, about the class variables.
When you do:
class Example(object):
itsProblem = "problem"
theExample = Example()
print(theExample.itsProblem)
You'll notice we first set a class variable, then we access an object (instance) variable. We never set this object variable but it works, how is that possible?
Well, Python tries to get first the object variable, but if it can't find it, will give you the class variable. Warning: the class variable is shared among instances, and the object variable is not.
As a conclusion, never use class variables to set default values to object variables. Use __init__
for that.
Eventually, you will learn that Python classes are instances and therefore objects themselves, which gives new insight to understanding the above. Come back and read this again later, once you realize that.
In Windows - for Fiddler say - using environment variables:
set http_proxy=http://127.0.0.1:8888
set https_proxy=http://127.0.0.1:8888
update: nowadays we have mobile and custom keyboards and we cannot continue trusting these arbitrary key codes such as 13 and 186. in other words, stop using event.which
/event.keyCode
and start using event.key
:
if (event.key === "Enter" || event.key === "ArrowUp" || event.key === "ArrowDown")
For my case, the culprit was the semicolon and double quotes in the password for prod DB. Our IT team use some tool to generate passwords, so it generated one with the semicolon and double quotes Connectionstring looks like
<add key="BusDatabaseConnectionString" value="Data Source=myserver;Initial Catalog=testdb;User Id=Listener;Password=BlaBla"';[]qrk/>
Got the password changed and it worked.
if you're doing a lot of this kind of thing you should consider using numpy
.
In [56]: import random, numpy
In [57]: lst = numpy.array([random.uniform(0, 5) for _ in range(1000)]) # example list
In [58]: a, b = 1, 3
In [59]: numpy.flatnonzero((lst > a) & (lst < b))[:10]
Out[59]: array([ 0, 12, 13, 15, 18, 19, 23, 24, 26, 29])
In response to Seanny123's question, I used this timing code:
import numpy, timeit, random
a, b = 1, 3
lst = numpy.array([random.uniform(0, 5) for _ in range(1000)])
def numpy_way():
numpy.flatnonzero((lst > 1) & (lst < 3))[:10]
def list_comprehension():
[e for e in lst if 1 < e < 3][:10]
print timeit.timeit(numpy_way)
print timeit.timeit(list_comprehension)
The numpy version is over 60 times faster.
Try this command:
git ls-files
This lists all of the files in the repository, including those that are only staged but not yet committed.

I saw this when changing rsync versions. In the older version, it worked to say:
rsync -e 'ssh ...
when the rsync.exe
and ssh.exe
were in the same directory.
With the newer version, I had to specify the path:
rsync -e './ssh ...
and it worked.
A little extension to the above answers. The trailing >
directs the input into the file, overwriting existing content. However, one particularly convenient use is the double arrow >>
that appends, adding your new content to the end of the file, as in:
cat <<EOF >> /etc/fstab
data_server:/var/sharedServer/authority/cert /var/sharedFolder/sometin/authority/cert nfs
data_server:/var/sharedServer/cert /var/sharedFolder/sometin/vsdc/cert nfs
EOF
This extends your fstab
without you having to worry about accidentally modifying any of its contents.
Not sure what your asking!
However
SELECT GETDATE()
Will get you the current date and time
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
Will get you just the date with time set to 00:00:00
Here's a creative idea using box-shadow
:
#header {
background-image: url("apple.jpg");
box-shadow: inset 0 0 99999px rgba(0, 120, 255, 0.5);
}
The background
sets the background for your element.
The box-shadow
is the important bit. It basically sets a really big shadow on the inside of the element, on top of the background, that is semi-transparent
It's a bit late but I think your issue may be that you've created a zero-length array, rather than an array of length 1.
A string is a series of characters followed by a string terminator ('\0'
). An empty string (""
) consists of no characters followed by a single string terminator character - i.e. one character in total.
So I would try the following:
string[1] = ""
Note that this behaviour is not the emulated by strlen
, which does not count the terminator as part of the string length.
In general, that's not how systems use GET requests. So, it will be hard to get your libraries to play along. In fact, the spec says that "If the request method is a case-sensitive match for GET or HEAD act as if data is null." So, I think you are out of luck unless the browser you are using doesn't respect that part of the spec.
You can probably setup an endpoint on your own server for a POST ajax request, then redirect that in your server code to a GET request with a body.
If you aren't absolutely tied to GET requests with the body being the data, you have two options.
POST with data: This is probably what you want. If you are passing data along, that probably means you are modifying some model or performing some action on the server. These types of actions are typically done with POST requests.
GET with query string data: You can convert your data to query string parameters and pass them along to the server that way.
url: 'somesite.com/models/thing?ids=1,2,3'
or you could just write the power function, with recursion as a added bonus
int power(int x, int y){
if(y == 0)
return 1;
return (x * power(x,y-1) );
}
yes,yes i know this is less effecient space and time complexity but recursion is just more fun!!
As long as the value of width is auto, the element can have horizontal margin, padding and border without becoming wider than its container (unless of course the sum of margin-left + border-left-width + padding-left + padding-right + border-right-width + margin-right is larger than the container). The width of its content box will be whatever is left when the margin, padding and border have been subtracted from the container’s width.
On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.

@Primary annotation when used against a method like below works good if the two data sources are on the same db location/server.
@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
return DataSourceBuilder.create().build();
}
@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
return DataSourceBuilder.create().build();
}
If the data sources are on different servers its better to use @Component along with @Primary annotation. The following code snippet works well on two different data sources at different locations
database1.datasource.url = jdbc:mysql://127.0.0.1:3306/db1
database1.datasource.username = root
database1.datasource.password = mysql
database1.datasource.driver-class-name=com.mysql.jdbc.Driver
database2.datasource1.url = jdbc:mysql://192.168.113.51:3306/db2
database2.datasource1.username = root
database2.datasource1.password = mysql
database2.datasource1.driver-class-name=com.mysql.jdbc.Driver
@Configuration
@Primary
@Component
@ComponentScan("com.db1.bean")
class DBConfiguration1{
@Bean("db1Ds")
@ConfigurationProperties(prefix="database1.datasource")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
}
@Configuration
@Component
@ComponentScan("com.db2.bean")
class DBConfiguration2{
@Bean("db2Ds")
@ConfigurationProperties(prefix="database2.datasource1")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
}
Unfortunately, strptime()
can only handle the timezone configured by your OS, and then only as a time offset, really. From the documentation:
Support for the
%Z
directive is based on the values contained intzname
and whetherdaylight
is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones).
strftime()
doesn't officially support %z
.
You are stuck with python-dateutil
to support timezone parsing, I am afraid.
You just need to a add the path of your PHP
file. In case you are using wamp
or have not installed it on the C drive.
There is no way to create a file without opening it There is os.mknod("newfile.txt")
(but it requires root privileges on OSX). The system call to create a file is actually open()
with the O_CREAT
flag. So no matter how, you'll always open the file.
So the easiest way to simply create a file without truncating it in case it exists is this:
open(x, 'a').close()
Actually you could omit the .close()
since the refcounting GC of CPython will close it immediately after the open()
statement finished - but it's cleaner to do it explicitely and relying on CPython-specific behaviour is not good either.
In case you want touch
's behaviour (i.e. update the mtime in case the file exists):
import os
def touch(path):
with open(path, 'a'):
os.utime(path, None)
You could extend this to also create any directories in the path that do not exist:
basedir = os.path.dirname(path)
if not os.path.exists(basedir):
os.makedirs(basedir)
What worked for me on Windows:
tools
folder from the ZIP archive to C:\Program Files (x86)\Android SDK\

, etc. directories appeared alongside tools

directoryIndexing a list is done using double bracket, i.e. hypo_list[[1]]
(e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table
does not return a table but a dataframe (see value section in ?read.table
). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.
Note: In R, the index for the first entry is a 1
(not 0
like in some other languages).
Dataframes
l <- list(anscombe, iris) # put dfs in list
l[[1]] # returns anscombe dataframe
anscombe[1:2, 2] # access first two rows and second column of dataset
[1] 10 8
l[[1]][1:2, 2] # the same but selecting the dataframe from the list first
[1] 10 8
Table objects
tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2) # put tables in a list
tbl1[1:2] # access first two elements of table 1
Now with the list
l[[1]] # access first table from the list
1 2 3 4 5
9 11 12 9 9
l[[1]][1:2] # access first two elements in first table
1 2
9 11
You can make git replace the protocol for you
git config --global url."https://".insteadOf git://
See more at SO Bower install using only https?
The more general answer is
UPDATE mysql.user SET host = {newhost} WHERE user = {youruser}
try something like
background: url(bgimage.jpg) no-repeat;
background-size: 100%;
There are several other version managers to consider, see for a few examples and one that's not listed there that I'll be giving a try soon is ch-ruby. I tried rbenv but had too many problems with it. RVM is my mainstay, though it sometimes has the odd problem (hence my wish to try ch-ruby when I get a chance). I wouldn't touch the system Ruby, as other things may rely on it.
I should add I've also compiled my own Ruby several times, and using the Hivelogic article (as Dave Everitt has suggested) is a good idea if you take that route.
I'm using Visual Studio Code v1.24.0 on a Mac.
By default, the Panel will appear on the bottom (You can change the default as well. Please refer to @Forres' answer: Moving Panel in Visual Studio Code to right side)
Here's the bottom/right toggle button for VS Code Panel:
Once I click on this button, the Panel moves to the right.
Moving it back is a little tricky though. As you can see, some of the buttons are hidden. This is because the width of the panel when it's aligned right is too small. We need to expand the column to see all the buttons.
This is how it'll look upon expansion:
Now, if you want to move the Panel back to the bottom, click on the toggle bottom/top button again.

A string literal is delimited by quotation marks and is of type char* not char.
Example: "hello"
So when you compare a char to a char* you will get that same compiling error.
char c = 'c';
char *p = "hello";
if(c==p)//compiling error
{
}
To fix use a char literal which is delimited by single quotes.
Example: 'c'
I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:
$("#addComment").click(function() {
if(typeof TinyMCE === "undefined") {
$.ajax({
url: "tinymce.js",
dataType: "script",
cache: true,
success: function() {
TinyMCE.init();
}
});
}
});
The getScript()
function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:
http://www.yoursite.com/js/tinymce.js?_=1399055841840
If a user clicks the #addComment
link multiple times, tinymce.js
will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.
===
Alternatively, in the getScript()
documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript()
function as follows:
jQuery.cachedScript = function( url, options ) {
// Allow user to set any option except for dataType, cache, and url
options = $.extend( options || {}, {
dataType: "script",
cache: true,
url: url
});
// Use $.ajax() since it is more flexible than $.getScript
// Return the jqXHR object so we can chain callbacks
return jQuery.ajax( options );
};
// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
console.log( textStatus );
});
===
Or, if you want to disable caching globally, you can do so using ajaxSetup()
as follows:
$.ajaxSetup({
cache: true
});
For using FusedLocationProviderClient with Google Play Services 11 and higher:
see here: How to get current Location in GoogleMap using FusedLocationProviderClient
For using (now deprecated) FusedLocationProviderApi:
If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.
The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.
Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.
It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo).
In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true)
and also before requesting location updates.

Result:
Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):
Prompt the user for Location permission by calling ActivityCompat.requestPermissions()
:
Move camera to current location and place Marker when the Location permission is granted:

I tried to use the Cast Extension (see https://stackoverflow.com/users/247402/stacker) in a situation where the Target Type contains a Property that is not present in the Source Type. It did not work, I'm not sure why. I refactored to the following extension that did work for my situation:
public static T Casting<T>(this Object source)
{
Type sourceType = source.GetType();
Type targetType = typeof(T);
var target = Activator.CreateInstance(targetType, false);
var sourceMembers = sourceType.GetMembers()
.Where(x => x.MemberType == MemberTypes.Property)
.ToList();
var targetMembers = targetType.GetMembers()
.Where(x => x.MemberType == MemberTypes.Property)
.ToList();
var members = targetMembers
.Where(x => sourceMembers
.Select(y => y.Name)
.Contains(x.Name));
PropertyInfo propertyInfo;
object value;
foreach (var memberInfo in members)
{
propertyInfo = typeof(T).GetProperty(memberInfo.Name);
value = source.GetType().GetProperty(memberInfo.Name).GetValue(source, null);
propertyInfo.SetValue(target, value, null);
}
return (T)target;
}
Note that I changed the name of the extension as the Name Cast conflicts with results from Linq. Hat tip https://stackoverflow.com/users/2093880/usefulbee

I got here because I was concerned that cr-lfs that I specified in C# strings were not being shown in SQl Server Management Studio query responses.
It turns out, they are there, but are not being displayed.
To "see" the cr-lfs, use the print statement like:
declare @tmp varchar(500)
select @tmp = msgbody from emailssentlog where id=6769;
print @tmp
if status
is of type Status
enum, status.name()
will give you its defined name.
Manifest.MF contains information about the files contained in the JAR file.
Whenever a JAR file is created a default manifest.mf file is created inside META-INF folder and it contains the default entries like this:
Manifest-Version: 1.0
Created-By: 1.7.0_06 (Oracle Corporation)
These are entries as “header:value” pairs. The first one specifies the manifest version and second one specifies the JDK version with which the JAR file is created.
Main-Class header: When a JAR file is used to bundle an application in a package, we need to specify the class serving an entry point of the application. We provide this information using ‘Main-Class’ header of the manifest file,
Main-Class: {fully qualified classname}
The ‘Main-Class’ value here is the class having main method. After specifying this entry we can execute the JAR file to run the application.
Class-Path header: Most of the times we need to access the other JAR files from the classes packaged inside application’s JAR file. This can be done by providing their fully qualified paths in the manifest file using ‘Class-Path’ header,
Class-Path: {jar1-name jar2-name directory-name/jar3-name}
This header can be used to specify the external JAR files on the same local network and not inside the current JAR.
Package version related headers: When the JAR file is used for package versioning the following headers are used as specified by the Java language specification:
Headers in a manifest
Header | Definition
-------------------------------------------------------------------
Name | The name of the specification.
Specification-Title | The title of the specification.
Specification-Version | The version of the specification.
Specification-Vendor | The vendor of the specification.
Implementation-Title | The title of the implementation.
Implementation-Version | The build number of the implementation.
Implementation-Vendor | The vendor of the implementation.
Package sealing related headers:
We can also specify if any particular packages inside a JAR file should be sealed meaning all the classes defined in that package must be archived in the same JAR file. This can be specified with the help of ‘Sealed’ header,
Name: {package/some-package/} Sealed:true
Here, the package name must end with ‘/’.
Enhancing security with manifest files:
We can use manifest files entries to ensure the security of the web application or applet it packages with the different attributes as ‘Permissions’, ‘Codebae’, ‘Application-Name’, ‘Trusted-Only’ and many more.
META-INF folder:
This folder is where the manifest file resides. Also, it can contain more files containing meta data about the application. For example, in an EJB module JAR file, this folder contains the EJB deployment descriptor for the EJB module along with the manifest file for the JAR. Also, it contains the xml file containing mapping of an abstract EJB references to concrete container resources of the application server on which it will be run.
Reference:
https://docs.oracle.com/javase/tutorial/deployment/jar/manifestindex.html
First check to see if the string's length needs to be shortened, then add spaces until it is as long as the field length.
fieldLength = 15
string1 = string1[0:15] # If it needs to be shortened, shorten it
while len(string1) < fieldLength:

heap space errors generally occur due to either bringing too much data back to the driver or the executor. In your code it does not seem like you are bringing anything back to the driver, but instead you maybe overloading the executors that are mapping an input record/row to another using the threeDReconstruction() method. I am not sure what is in the method definition but that is definitely causing this overloading of the executor. Now you have 2 options,
I would advise being careful with the increase and use only as much as you need. Each job is unique in terms of its memory requirements, so I would advise empirically trying different values increasing every time by a power of 2 (256M,512M,1G .. and so on)
You will arrive at a value for the executor memory that will work. Try re-running the job with this value 3 or 5 times before settling for this configuration.

Right-click your project->Properties->Configuration Properties->C/C++ ->Preprocessor->Preprocessor Definitions.
You've almost done it. However setting flex: 0 0 <basis>
declaration to the columns would prevent them from growing/shrinking; And the <basis>
parameter would define the width of columns.
In addition, you could use CSS3 calc()
expression to specify the height
of columns with the respect to the height of the header.
#productShowcaseTitle {
flex: 0 0 100%; /* Let it fill the entire space horizontally */
height: 100px;
}
#productShowcaseDetail,
#productShowcaseThumbnailContainer {
height: calc(100% - 100px); /* excluding the height of the header */
}
#productShowcaseContainer {_x000D_
display: flex;_x000D_
flex-flow: row wrap;_x000D_
_x000D_
height: 600px;_x000D_

}_x000D_

_x000D_
#productShowcaseDetail {_x000D_

(Vendor prefixes omitted due to brevity)
Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div>
element, it would be achieved without using calc()
as follows:
<div class="contentContainer"> <!-- Added wrapper -->
<div id="productShowcaseDetail"></div>
<div id="productShowcaseThumbnailContainer"></div>
</div>
#productShowcaseContainer {
display: flex;
flex-direction: column;

}
.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }

Use a return statement!
return;
or
if (condition) return;
You don't need to (and can't) specify any values, if your method returns void
.
The best way to configure the standard headers for your project is by setting the compilerPath
property to the configurations in your c_cpp_properties.json
file. It is not recommended to add system include paths to the includePath
property.
Another option if you prefer not to use c_cpp_properties.json
is to set the C_Cpp.default.compilerPath
setting.
Different approach for creating columns string
create table #temp
(
date datetime,
category varchar(3),
amount money
)
insert into #temp values ('1/1/2012', 'ABC', 1000.00)
insert into #temp values ('2/1/2012', 'DEF', 500.00)
insert into #temp values ('2/1/2012', 'GHI', 800.00)
insert into #temp values ('2/10/2012', 'DEF', 700.00)
insert into #temp values ('3/1/2012', 'ABC', 1100.00)
DECLARE @cols AS NVARCHAR(MAX)='';
DECLARE @query AS NVARCHAR(MAX)='';
SELECT @cols = @cols + QUOTENAME(category) + ',' FROM (select distinct category from #temp ) as tmp
select @cols = substring(@cols, 0, len(@cols)) --trim "," at end
set @query =
'SELECT * from
(
select date, amount, category from #temp
) src
pivot
(
max(amount) for category in (' + @cols + ')
) piv'
execute(@query)
drop table #temp
Result
date ABC DEF GHI

For those who prefer a bit more practical learning, select the segue in dock, open the attribute inspector and switch between different kinds of segues (dropdown "Kind"). This will reveal options specific for each of them: for example you can see that "present modally" allows you to choose a transition type etc.
left:auto;
This will default the left
back to the browser default.
So if you have your Markup/CSS as:
<div class="myClass"></div>
.myClass
{
position:absolute;
left:0;
}
When setting RTL, you could change to:
<div class="myClass rtl"></div>
.myClass
{
position:absolute;
left:0;
}
.myClass.rtl
{
left:auto;
right:0;
}

Try this example and see if it fits your needs, there are three main aspects to it.
Line.Stretch is set to fill.
For horizontal lines the VerticalAlignment of the line is set Bottom, and for VerticalLines the HorizontalAlignment is set to Right.
We then need to tell the line how many rows or columns to span, this is done by binding to either RowDefinitions or ColumnDefintions count property.
<Style x:Key="horizontalLineStyle" TargetType="Line" BasedOn="{StaticResource lineStyle}">
<Setter Property="X2" Value="1" />
<Setter Property="VerticalAlignment" Value="Bottom" />
<Setter Property="Grid.ColumnSpan"

One Liner (pure Java)
list.toString().replace(", ", ",").replaceAll("[\\[.\\]]", "");
dd()
dumps the variable and ends the execution of the script (1), so surrounding it with <pre>
tags will leave it broken. Just use good ol' var_dump()
(or print_r()
if you know it's an array)
Route::get('/', function()
{
echo '<pre>';
var_dump(User::all());
echo '</pre>';
//exit; <--if you want
});
Update:
I think you could format down what's shown by having Laravel convert the model object to array:
Route::get('/', function()
{
echo '<pre>';
$user = User::where('person_id', '=', 1);
var_dump($user->toArray()); // <---- or toJson()
echo '</pre>';
//exit; <--if you want
});
(1) For the record, this is the implementation of dd():
function dd()
{
array_map(function($x) { var_dump($x); }, func_get_args()); die;
}
Before you run make oldconfig
, you need to copy a kernel configuration file from an older kernel into the root directory of the new kernel.
You can find a copy of the old kernel configuration file on a running system at /boot/config-3.11.0
. Alternatively, kernel source code has configs in linux-3.11.0/arch/x86/configs/{i386_defconfig / x86_64_defconfig}
If your kernel source is located at /usr/src/linux
:
cd /usr/src/linux
cp /boot/config-3.9.6-gentoo .config
make oldconfig
Reader's Digest: (Spark 2.x)
For Example, if you have 3 directories holding csv files:
dir1, dir2, dir3
You then define paths as a string of comma delimited list of paths as follows:
paths = "dir1/,dir2/,dir3/*"
Then use the following function and pass it this paths variable
def get_df_from_csv_paths(paths):
df = spark.read.format("csv").option("header", "false").\
schema(custom_schema).\
option('delimiter', '\t').\
option('mode', 'DROPMALFORMED').\
load(paths.split(','))
return df
By then running:
df = get_df_from_csv_paths(paths)
You will obtain in df a single spark dataframe containing the data from all the csvs found in these 3 directories.
===========================================================================
Full Version:
In case you want to ingest multiple CSVs from multiple directories you simply need to pass a list and use wildcards.
For Example:
if your data_path looks like this:
's3://bucket_name/subbucket_name/2016-09-*/184/*,
s3://bucket_name/subbucket_name/2016-10-*/184/*,
s3://bucket_name/subbucket_name/2016-11-*/184/*,
s3://bucket_name/subbucket_name/2016-12-*/184/*, ... '
you can use the above function to ingest all the csvs in all these directories and subdirectories at once:
This would ingest all directories in s3 bucket_name/subbucket_name/ according to the wildcard patterns specified. e.g. the first pattern would look in
bucket_name/subbucket_name/
for all directories with names starting with
2016-09-
and for each of those take only the directory named
184
and within that subdirectory look for all csv files.
And this would be executed for each of the patterns in the comma delimited list.
This works way better than union..
zIndex
is part of javaScript notation.(camelCase)
but jQuery.css uses same as CSS syntax.
so it is z-index
.
you forgot .css("attr","value"). use ' or " in both, attr and val. so,
.css("z-index","3000");
s = 'sdsd'
print (s.upper())
upper = raw_input('type in something lowercase.')
lower = raw_input('type in the same thing caps lock.')
print upper.upper()
print lower.lower()
Got this error, too, after installing php 7.3. I had it resolved upgrading just my old php's versions (5.6 and 7.0, not from the official repos).
The maintainers had compiled new php versions against the current icu4c.
In my case, PHP 7 got from 0.31 to 0.33, and the problem was solved.

I'm not really sure if this adds anything but,
Caller saved means that the caller has to save the registers because they will be clobbered in the call and have no choice but to be left in a clobbered state after the call returns (for instance, the return value being in eax
for cdecl. It makes no sense for the return value to be restored to the value before the call by the callee, because it is a return value).
Callee saved means that the callee has to save the registers and then restore them at the end of the call because they have the guarantee to the caller of containing the same values after the function returns, and it is possible to restore them, even if they are clobbered at some point during the call.
The issue with the above definition though is that for instance on Wikipedia cdecl, it says eax
, ecx
and edx
are caller saved and rest are callee saved, this suggests that the caller must save all 3 of these registers, when it might not if none of these registers were used by the caller in the first place. In which case caller 'saved' becomes a misnomer, but 'call clobbered' still correctly applies. This is the same with 'the rest' being called callee saved. It implies that all other x86 registers will be saved and restored by the callee when this is not the case if some of the registers are never used in the call anyway. With cdecl, eax:edx
may be used to return a 64 bit value. I'm not sure why ecx
is also caller saved if needed, but it is.
This answer from here helped me:
You should take a look at the build path of your project to check whether the referenced libraries are still there. So right-click on your project, then "Properties -> Java Build Path -> Libraries" and check whether you still have the spring library JARs in the place that is mentioned there. If not, just re-add them to your classpath within this dialog.
Each node is named uniquely and knows who it is connected to. The List of connections allows for a Node to be connected to an arbitrary number of other nodes.
public class Node {
public String name;
public List<Edge> connections;
}
Each connection is directed, has a start and an end, and is weighted.
public class Edge {
public Node start;
public Node end;
public double weight;
}
A graph is just your collection of nodes. Instead of List<Node>
consider Map<String, Node>
for fast lookup by name.
public class Graph {
List<Node> nodes;
}
That can happen if for some reason a x86 resource is loaded from a x64 machine. To avoid that explicitly, add this preprocessor directive to stdafx.h (of course, in my example the problematic resource is Windows Common Controls DLL.
#if defined(_WIN64)
#pragma comment(linker, "\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df'\"")

To assign value to a single Form control/individually, I propose to use setValue in the following way:
this.editqueForm.get('user').setValue(this.question.user);
this.editqueForm.get('questioning').setValue(this.question.questioning);
That particular phrasing is by James Iry, from his highly entertaining Brief, Incomplete and Mostly Wrong History of Programming Languages, in which he fictionally attributes it to Philip Wadler.
The original quote is from Saunders Mac Lane in Categories for the Working Mathematician, one of the foundational texts of Category Theory. Here it is in context, which is probably the best place to learn exactly what it means.
But, I'll take a stab. The original sentence is this:
All told, a monad in X is just a monoid in the category of endofunctors of X, with product × replaced by composition of endofunctors and unit set by the identity endofunctor.
X here is a category. Endofunctors are functors from a category to itself (which is usually all Functor
s as far as functional programmers are concerned, since they're mostly dealing with just one category; the category of types - but I digress). But you could imagine another category which is the category of "endofunctors on X". This is a category in which the objects are endofunctors and the morphisms are natural transformations.
And of those endofunctors, some of them might be monads. Which ones are monads? Exactly the ones which are monoidal in a particular sense. Instead of spelling out the exact mapping from monads to monoids (since Mac Lane does that far better than I could hope to), I'll just put their respective definitions side by side and let you compare:
* -> *
with a Functor
instance)join
in Haskell)return
in Haskell)With a bit of squinting you might be able to see that both of these definitions are instances of the same abstract concept.
It's hard to know without a benchmark, but if you have lots of items in your ArrayList and the average size is lower, it might be faster to make a new ArrayList.
http://www.docjar.com/html/api/java/util/ArrayList.java.html
public void clear() {
modCount++;
// Let gc do its work
for (int i = 0; i < size; i++)
elementData[i] = null;
size = 0;
}
What I do is create a view that performs the same select as the table variable and link that view into the second view. So a view can select from another view. This achieves the same result
I came into the same situation. As a workaround, I just created a view
(If you have privileges) and described it and dropped it later. :)
Try This Simple and Effective
.home > span + .red{
border:1px solid red;
}
Here's a simple one, single for loop:
#define FOREACH(type, array, size) do { \
type it = array[0]; \
for(int i = 0; i < size; i++, it = array[i])
#define ENDFOR } while(0);
int array[] = { 1, 2, 3, 4, 5 };
FOREACH(int, array, 5)
{
printf("element: %d. index: %d\n", it, i);
}
ENDFOR
Gives you access to the index should you want it (i
) and the current item we're iterating over (it
). Note you might have naming issues when nesting loops, you can make the item and index names be parameters to the macro.
Edit: Here's a modified version of the accepted answer foreach
. Lets you specify the start
index, the size
so that it works on decayed arrays (pointers), no need for int*
and changed count != size
to i < size
just in case the user accidentally modifies 'i' to be bigger than size
and get stuck in an infinite loop.
#define FOREACH(item, array, start, size)\
for(int i = start, keep = 1;\
keep && i < size;\
keep = !keep, i++)\
for (item = array[i]; keep; keep = !keep)
int array[] = { 1, 2, 3, 4, 5 };
FOREACH(int x, array, 2, 5)
printf("index: %d. element: %d\n", i, x);
Output:
index: 2. element: 3
index: 3. element: 4
index: 4. element: 5
The head
command can get the first n
lines. Variations are:
head -7 file
head -n 7 file
head -7l file
which will get the first 7 lines of the file called "file"
. The command to use depends on your version of head
. Linux will work with the first one.
To append lines to the end of the same file, use:
echo 'first line to add' >>file
echo 'second line to add' >>file
echo 'third line to add' >>file
or:
echo 'first line to add
second line to add
third line to add' >>file
to do it in one hit.
So, tying these two ideas together, if you wanted to get the first 10 lines of the input.txt
file to output.txt
and append a line with five "="
characters, you could use something like:
( head -10 input.txt ; echo '=====' ) > output.txt
In this case, we do both operations in a sub-shell so as to consolidate the output streams into one, which is then used to create or overwrite the output file.
Use the standard XPath function contains().
Function: boolean contains(string, string)
The contains function returns true if the first argument string contains the second argument string, and otherwise returns false
The query either returned no rows or is erroneus, thus FALSE
is returned. Change it to
if (!$dbc || mysqli_num_rows($dbc) == 0)
mysqli_num_rows
:
Return Values
Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.
When you use angle brackets, the compiler searches for the file in the include path list. When you use double quotes, it first searches the current directory (i.e. the directory where the module being compiled is) and only then it'll search the include path list.
So, by convention, you use the angle brackets for standard includes and the double quotes for everything else. This ensures that in the (not recommended) case in which you have a local header with the same name as a standard header, the right one will be chosen in each case.
For python 2.7 I had the same issue Just use "from __future__ import print_function" without quotes to resolve this issue.This Ensures Python 2.6 and later Python 2.x can use Python 3.x print function.
As pointed out in the other answers, C++ can support finally
-like functionality. The implementation of this functionality that is probably closest to being part of the standard language is the one accompanying the C++ Core Guidelines, a set of best practices for using C++ edited by Bjarne Stoustrup and Herb Sutter. An implementation of finally
is part of the Guidelines Support Library (GSL). Throughout the Guidelines, use of finally
is recommended when dealing with old-style interfaces, and it also has a guideline of its own, titled Use a final_action object to express cleanup if no suitable resource handle is available.
So, not only does C++ support finally
, it is actually recommended to use it in a lot of common use-cases.
An example use of the GSL implementation would look like:
#include <gsl/gsl_util.h>
void example()
{
int handle = get_some_resource();
auto handle_clean = gsl::finally([&handle] { clean_that_resource(handle); });
// Do a lot of stuff, return early and throw exceptions.
// clean_that_resource will always get called.
}
The GSL implementation and usage is very similar to the one in Paolo.Bolzoni's answer. One difference is that the object created by gsl::finally()
lacks the disable()
call. If you need that functionality (say, to return the resource once it's assembled and no exceptions are bound to happen), you might prefer Paolo's implementation. Otherwise, using GSL is as close to using standardized features as you will get.
New Updates for iOS Device Support file. Don't need to update Xcode.
You just need to add support file to Xcode's DeviceSupport folder.
iOS 12.3.1 Developer Disk Image
Extract the zip and then copy folder.
Paste this folder in this path
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Quit the Xcode and restart, it will work.
For me the problem was a configuration file that was missing an Element.

You need to install it in a directory in your home folder, and somehow manipulate the PYTHONPATH so that directory is included.
The best and easiest is to use virtualenv. But that requires installation, causing a catch 22. :) But check if virtualenv is installed. If it is installed you can do this:
$ cd /tmp
$ virtualenv foo
$ cd foo
$ ./bin/python
Then you can just run the installation as usual, with /tmp/foo/python setup.py install. (Obviously you need to make the virtual environment in your a folder in your home directory, not in /tmp/foo. ;) )
If there is no virtualenv, you can install your own local Python. But that may not be allowed either. Then you can install the package in a local directory for packages:
$ wget http://pypi.python.org/packages/source/s/six/six-1.0b1.tar.gz#md5=cbfcc64af1f27162a6a6b5510e262c9d
$ tar xvf six-1.0b1.tar.gz
$ cd six-1.0b1/
$ pythonX.X setup.py install --install-dir=/tmp/frotz
Now you need to add /tmp/frotz/pythonX.X/site-packages
to your PYTHONPATH, and you should be up and running!
Comparable is used to compare instances of your class. We can compare instances from many ways that is why we need to implement a method compareTo
in order to know how (attributes) we want to compare instances.

Here is a good example how to use comparable in Java:
http://www.onjava.com/pub/a/onjava/2003/03/12/java_comp.html?page=2
see this code what i am used in my application
String data="{'foo':'bar','coolness':2.0, 'altitude':39000, 'pilot':{'firstName':'Buzz','lastName':'Aldrin'}, 'mission':'apollo 11'}";
I retrieved like this
JSONObject json = (JSONObject) JSONSerializer.toJSON(data);
double coolness = json.getDouble( "coolness" );
int altitude = json.getInt( "altitude" );
JSONObject pilot = json.getJSONObject("pilot");
String firstName = pilot.getString("firstName");
String lastName = pilot.getString("lastName");
System.out.println( "Coolness: " + coolness );
System.out.println( "Altitude: " + altitude );
System.out.println( "Pilot: " + lastName );
Here is a quasi-oneliner that does it:
String[] prependedArray = new ArrayList<String>() {
{
add("newElement");
addAll(Arrays.asList(originalArray));
}
}.toArray(new String[0]);
Yes you can put the break-point on client side page in Visual studio
First Put the debugger in java-script code and run the page in browser
debugger
After that open your page in browser and view the inspect element you see the following view
You can call the method like pump.getPumps()
. By adding @classmethod
decorator on the method. A class method receives the class as the implicit first argument, just like an instance method receives the instance.
class Pump:
def __init__(self):
print ("init") # never prints
@classmethod
def getPumps(cls):
# Open database connection
# some stuff here that never gets executed because of error
So, simply call Pump.getPumps()
.
In java, it is termed as static
method.
The cursor: pointer;
rule has been restored, so buttons will now by default have the cursor on hover:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">_x000D_
<button type="button" class="btn btn-success">Sample Button</button>
_x000D_
No, there isn't. You need to make some custom CSS for this.
If you just need a link that looks like a button (with pointer), use this:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">_x000D_
<a class="btn btn-success" href="#" role="button">Sample Button</a>

Along the lines of what I mentioned in this post. I recommend you use the SIGAR API. I use the SIGAR API in one of my own applications and it is great. You'll find it is stable, well supported, and full of useful examples. It is open-source with a GPL 2 Apache 2.0 license. Check it out. I have a feeling it will meet your needs.
Using Java and the Sigar API you can get Memory, CPU, Disk, Load-Average, Network Interface info and metrics, Process Table information, Route info, etc.
For Windows and Python 3.x, my two cents contribution about renaming the file on download :
pip install wget
import wget
wget.download('Url', 'C:\\PathToMyDownloadFolder\\NewFileName.extension')
Truely working command line example :
python -c "import wget; wget.download(""https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.2.tar.xz"", ""C:\\Users\\TestName.TestExtension"")"
Note : 'C:\\PathToMyDownloadFolder\\NewFileName.extension' is not mandatory. By default, the file is not renamed, and the download folder is your local path.
Use JavaScript by adding an onChange
attribute to your input tags
<input onChange="this.form.submit()" ... />
For large files, what I did was read the file line by line and read each line into an array. Then, once the array reached a certain size, append it to a new file.
for line in open("file.txt", "r"):
list.append(line)
if len(list) == 1000000:
output.writelines(list)
del list[:]

The redis SET command stores a string, not arbitrary data. You could try using the redis HSET command to store the dict as a redis hash with something like
for k,v in my_dict.iteritems():
r.hset('my_dict', k, v)
but the redis datatypes and python datatypes don't quite line up. Python dicts can be arbitrarily nested, but a redis hash is going to require that your value is a string. Another approach you can take is to convert your python data to string and store that in redis, something like
r.set('this_dict', str(my_dict))
and then when you get the string out you will need to parse it to recreate the python object.
In Angular 6, you can do this:
In your service file:
function_name(data) {
const url = `the_URL`;
let input = new FormData();
input.append('url', data); // "url" as the key and "data" as value
return this.http.post(url, input).pipe(map((resp: any) => resp));
}
In component.ts file: in any function say xyz,
xyz(){
this.Your_service_alias.function_name(data).subscribe(d => { // "data" can be your file or image in base64 or other encoding
console.log(d);
});
}
Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

Previous answer can be shortened and be more readable.
$('#commentForm').submit(function () {
$(this).append($.map(params, function (param) {

})
}))
});

This is an alternative:
- name: Install this only for local dev machine
pip: name=pyramid
delegate_to: localhost
.NET has an easy function to do that in the String
class.
Just use:
.ToString().PadLeft(4, '0') // that will fill your number with 0 on the left, up to 4 length
int i = 1;
i.toString().PadLeft(4,'0') // will return "0001"
Same as the other answers (disabled isn't sent to the server, readonly is) but some browsers prevent highlighting of a disabled form, while read-only can still be highlighted (and copied).
http://www.w3schools.com/tags/att_input_disabled.asp
http://www.w3schools.com/tags/att_input_readonly.asp
A read-only field cannot be modified. However, a user can tab to it, highlight it, and copy the text from it.
Use vertical-align:top; for the element you want at the top, as I have demonstrated on your jsfiddle.
You can try these. 1. stringify your JSON Object before calling the server action via ajax 2. deserialize the string in the action then use the data as a dictionary.
Javascript sample below (sending the JSON Object
$.ajax(
{
type: 'POST',
url: 'TheAction',
data: { 'data': JSON.stringify(theJSONObject)
}
})
Action (C#) sample below
[HttpPost]
public JsonResult TheAction(string data) {
string _jsonObject = data.Replace(@"\", string.Empty);
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
Dictionary<string, string> jsonObject = serializer.Deserialize<Dictionary<string, string>>(_jsonObject);
return Json(new object{status = true});
}
You have to include one more jar.
xmlbeans-2.3.0.jar
Add this and try.
Note: It is required for the files with .xlsx formats only, not for just .xls formats.
=A1/(24*60*60) + DATE(1970;1;1)
should work with seconds.
=(A1/86400/1000)+25569
if your time is in milliseconds, so dividing by 1000 gives use the correct date
Don't forget to set the type to Date
on your output cell. I tried it with this date: 1504865618099
which is equal to 8-09-17 10:13
.
border:0;
outline:none;
box-shadow:none;
This should do the trick.

No, there is no built-in MySQL command for that. There are various tools and scripts that support it, you can kill some connections manually or restart the server (but that will be slower).
Use SHOW PROCESSLIST
to view all connections, and KILL
the process ID's you want to kill.
You could edit the timeout setting to have the MySQL daemon kill the inactive processes itself, or raise the connection count. You can even limit the amount of connections per username, so that if the process keeps misbehaving, the only affected process is the process itself and no other clients on your database get locked out.
If you can't connect yourself anymore to the server, you should know that MySQL always reserves 1 extra connection for a user with the SUPER
privilege. Unless your offending process is for some reason using a username with that privilege...
Then after you can access your database again, you should fix the process (website) that's spawning that many connections.
here is an example i did on change i get children of the first select in second select
jQuery(document).ready(function($) {
$('.your_select').change(function() {
$.ajaxSetup({
headers:{'X-CSRF-TOKEN': $("meta[name='csrf-token']").attr('content')}
});
$.ajax({
type:'POST',
url: 'Link',
data:{
'id': $(this).val()
},
success:function(r){
$.each(r, function(res) {
console.log(r[res].Nom);
$('.select_to_populate').append($("<option />").val(r[res].id).text(r[res].Nom));
});
},error:function(r) {
alert('Error');
}
});
});
});enter code here
Just find the top position of the element you've already determined https://www.w3schools.com/Jsref/prop_element_offsettop.asp then scroll to this position via scrollTo
method https://www.w3schools.com/Jsref/met_win_scrollto.asp
Something like this should work:
handleScrollToElement(event) {
const tesNode = ReactDOM.findDOMNode(this.refs.test)
if (some_logic){
window.scrollTo(0, tesNode.offsetTop);
}
}
render() {
return (
<div>
<div ref="test"></div>
</div>)
}
UPDATE:
since React v16.3 the React.createRef()
is preferred
constructor(props) {
super(props);
this.myRef = React.createRef();
}
handleScrollToElement(event) {
if (<some_logic>){
window.scrollTo(0, this.myRef.current.offsetTop);
}
}
render() {
return (
<div>
<div ref={this.myRef}></div>
</div>)
}
If you're checking for explicit types, why are you declaring those variables as T
's?
T HowToCast<T>(T t)
{
if (typeof(T) == typeof(string))
{
var newT1 = "some text";
var newT2 = t; //this builds but I'm not sure what it does under the hood.
var newT3 = t.ToString(); //for sure the string you want.
}
return t;
}
I had this problem in windows. Most of the answers are not as recommended by anaconda, you should not add the path to the environment variables as it can break other things. Instead you should use anaconda prompt as mentioned in the top answer.
However, this may also break. In this case right click on the shortcut, go to shortcut tab, and the target value should read something like:
%windir%\System32\cmd.exe "/K" C:\Users\myUser\Anaconda3\Scripts\activate.bat C:\Users\myUser\Anaconda3
In JBoss Developer 4.0 and above (Eclipse-based), this is a tad easier. Just right-click on your file or folder that contains xml-based files, choose "Exclude Validation", then click "Yes" to confirm. Then right-click the same files/folder again and click on "Validate", which will remove the errors with a confirmation.
One issue I found with all the existing answers is that the margins aren't preserved. This is because they all override the android:windowBackground
attribute, which is responsible for margins, with a solid color. However, I did some digging in the Android SDK and found the default window background drawable, and modified it a bit to allow transparent dialogs.
First, copy /platforms/android-22/data/res/drawable/dialog_background_material.xml to your project. Or, just copy these lines into a new file:
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:inset="16dp">
<shape android:shape="rectangle">
<corners android:radius="2dp" />
<solid android:color="?attr/colorBackground" />
</shape>
</inset>
Notice that android:color
is set to ?attr/colorBackground
. This is the default solid grey/white you see. To allow the color defined in android:background
in your custom style to be transparent and show the transparency, all we have to do is change ?attr/colorBackground
to @android:color/transparent
. Now it will look like this:
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:inset="16dp">
<shape android:shape="rectangle">
<corners android:radius="2dp" />
<solid android:color="@android:color/transparent" />
</shape>
</inset>
After that, go to your theme and add this:
<style name="MyTransparentDialog" parent="@android:style/Theme.Material.Dialog">
<item name="android:windowBackground">@drawable/newly_created_background_name</item>
<item name="android:background">@color/some_transparent_color</item>
</style>
Make sure to replace newly_created_background_name
with the actual name of the drawable file you just created, and replace some_transparent_color
with the desired transparent background.
After that all we need to do is set the theme. Use this when creating the AlertDialog.Builder
:
AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.MyTransparentDialog);
Then just build, create, and show the dialog as usual!
As a complement of the answers above, here is a sum up about Redirections:
EDIT: This graphic is not entirely correct.
The first example does not use stdin at all, it's passing "hello" as an argument to the echo command.
The graphic also says 2>&1 has the same effect as &> however
ls Documents ABC > dirlist 2>&1
#does not give the same output as
ls Documents ABC > dirlist &>
This is because &> requires a file to redirect to, and 2>&1 is simply sending stderr into stdout
On my Centos Linux system I did the following:
1) Started the Python interpreter (I'm using 2.6.6)
2) Ran the following code:
import platform
print(platform.architecture())
and it gave me
(64bit, 'ELF')
if you can use HTML5 you can do <input type="number" />
If not you will have to either do it through javascript as you said it doesnt get submited to do it from codebehind.
<input id="numbersOnly" onkeypress='validate()' />
function validate(){
var returnString;
var text = document.getElementByID('numbersOnly').value;
var regex = /[0-9]|\./;
var anArray = text.split('');
for(var i=0; i<anArray.length; i++){
if(!regex.test(anArray[i]))
{
anArray[i] = '';
}
}
for(var i=0; i<anArray.length; i++) {
returnString += anArray[i];
}
document.getElementByID('numbersOnly').value = returnString;
}
P.S didnt test the code but it should be more or less correct if not check for typos :D You might wanna add a few more things like what to do if the string is null or empty etc. Also you could make this quicker :D
Usual way is to go with PHP and ajax. But for your requirement, below will work fine.

A callback function is one that should be called when a certain condition is met. Instead of being called immediately, the callback function is called at a certain point in the future.
Typically it is used when a task is being started that will finish asynchronously (ie will finish some time after the calling function has returned).
For example, a function to request a webpage might require its caller to provide a callback function that will be called when the webpage has finished downloading.
What really helped me to change the type of the object in MondoDB was just this simple line, perhaps mentioned before here...:
db.Users.find({age: {$exists: true}}).forEach(function(obj) {
obj.age = new NumberInt(obj.age);
db.Users.save(obj);
});
Users are my collection and age is the object which had a string instead of an integer (int32).
Java 8 now supports BASE64 Encoding and Decoding. You can use the following classes:
java.util.Base64
, java.util.Base64.Encoder
and java.util.Base64.Decoder
.
Example usage:
// encode with padding
String encoded = Base64.getEncoder().encodeToString(someByteArray);
// encode without padding
String encoded = Base64.getEncoder().withoutPadding().encodeToString(someByteArray);
// decode a String
byte [] barr = Base64.getDecoder().decode(encoded);
According to the Android Development Guide:
px = dp * (dpi / 160)
But often you'll want do perform this the other way around when you receive a design that's stated in pixels. So:
dp = px / (dpi / 160)
If you're on a 240dpi device this ratio is 1.5 (like stated before), so this means that a 60px icon equals 40dp in the application.
Take a look at Numeral.js. It can format numbers, currency, percentages and has support for localization.
Have a look at CGI in Wikipedia. CGI is a protocol between the web server and a external program or a script that handles the input and generates output that is sent to the browser.
CGI is a simply a way for web server and a program to communicate, nothing more, nothing less. Here the server manages the network connection and HTTP protocol and the program handles input and generates output that is sent to the browser. CGI script can be basically any program that can be executed by the webserver and follows the CGI protocol. Thus a CGI program can be implemented, for example, in C. However that is extremely rare, since C is not very well suited for the task.
/cgi-bin/*.cgi
is a simply a path where people commonly put their CGI script. Web server are commonly configured by default to fetch CGI scripts from that path.
a CGI script can be implemented also in PHP, but all PHP programs are not CGI scripts. If webserver has embedded PHP interpreter (e.g. mod_php in Apache), then the CGI phase is skipped by more efficient direct protocol between the web server and the interpreter.
Whether you have implemented a CGI script or not depends on how your script is being executed by the web server.
The first case will fail when JS is off. It's also a little bit slower since JS must be parsed first (DOM must be loaded). However JS is safer since the destination doesn't know the referer and your redirect might be tracked (referers aren't reliable in general yet this is something).
You can also use meta refresh tag. It also requires DOM to be loaded.
A Task can be seen as a convenient and easy way to execute something asynchronously and in parallel.
Normally a Task is all you need, I cannot remember if I have ever used a thread for something else than experimentation.
You can accomplish the same with a thread (with lots of effort) as you can with a task.
Thread
int result = 0;
Thread thread = new System.Threading.Thread(() => {
result = 1;
});
thread.Start();
thread.Join();
Console.WriteLine(result); //is 1
Task
int result = await Task.Run(() => {
return 1;
});
Console.WriteLine(result); //is 1
A task will by default use the Threadpool, which saves resources as creating threads can be expensive. You can see a Task as a higher level abstraction upon threads.
As this article points out, task provides following powerful features over thread.
Tasks are tuned for leveraging multicores processors.
If system has multiple tasks then it make use of the CLR thread pool internally, and so do not have the overhead associated with creating a dedicated thread using the Thread. Also reduce the context switching time among multiple threads.
Wait on a set of tasks, without a signaling construct.
We can chain tasks together to execute one after the other.
Establish a parent/child relationship when one task is started from another task.
Child task exception can propagate to parent task.
Task support cancellation through the use of cancellation tokens.
Asynchronous implementation is easy in task, using’ async’ and ‘await’ keywords.
I had the same problem with property Enabled
and I discovered a first chance exception
raised because of it is not thread-safe.
I found solution about "How to update the GUI from another thread in C#?" here https://stackoverflow.com/a/661706/1529139 And it works !
Solution from EvilRygy didn't worked for me. In Postgres you can do another workaround:
$ids = array(1,2,3,7,8,9);
$db = new PDO(...);
$stmt = $db->prepare(
'SELECT *
FROM table
WHERE id = ANY (string_to_array(:an_array, ','))'
);
$stmt->bindParam(':an_array', implode(',', $ids));
$stmt->execute();
Try this. You can pass either unix timestamp, or datetime string
public static function convertToTimezone($timestamp, $fromTimezone, $toTimezone, $format='Y-m-d H:i:s')
{
$datetime = is_numeric($timestamp) ?
DateTime::createFromFormat ('U' , $timestamp, new DateTimeZone($fromTimezone)) :
new DateTime($timestamp, new DateTimeZone($fromTimezone));
$datetime->setTimezone(new DateTimeZone($toTimezone));
return $datetime->format($format);
}
Documented couple of design issues with this in a comment above. Short story, in Oracle, you need to limit the results manually when you have large tables and/or tables with same column names (and you don't want to explicit type them all out and rename them all). Easy solution is to figure out your breakpoint and limit that in your query. Or you could also do this in the inner query if you don't have the conflicting column names constraint. E.g.
WHERE m_api_log.created_date BETWEEN TO_DATE('10/23/2015 05:00', 'MM/DD/YYYY HH24:MI')
AND TO_DATE('10/30/2015 23:59', 'MM/DD/YYYY HH24:MI')
will cut down the results substantially. Then you can ORDER BY or even do the outer query to limit rows.
Also, I think TOAD has a feature to limit rows; but, not sure that does limiting within the actual query on Oracle. Not sure.
You can loop throw the rows and columns, checking for nulls, keeping track of whether there's a null with a bool, then check it after looping through the table and handle it.
//your DataTable, replace with table get code
DataTable table = new DataTable();
bool tableHasNull = false;
foreach (DataRow row in table.Rows)
{
foreach (DataColumn col in table.Columns)
{
//test for null here
if (row[col] == DBNull.Value)
{
tableHasNull = true;
}
}
}
if (tableHasNull)
{
//handle null in table
}
You can also come out of the foreach loop with a break statement e.g.
//test for null here
if (row[col] == DBNull.Value)
{
tableHasNull = true;
break;
}
To save looping through the rest of the table.
I resolved this by adding @Transactional
to the base/generic Hibernate DAO implementation class (the parent class which implements the saveOrUpdate() method inherited by the DAO I use in the main program), i.e. the @Transactional
needs to be specified on the actual class which implements the method. My assumption was instead that if I declared @Transactional
on the child class then it included all of the methods that were inherited by the child class. However it seems that the @Transactional
annotation only applies to methods implemented within a class and not to methods inherited by a class.

1- Just open https://developer.android.com/studio/index.html
2- scroll down to the bottom of that page
3- download last version of tools for your OS (for example tools_r25.2.3-windows.zip)
4- Unzip it
5- Delete folder tools from previous Android Sdk folder
6- Copy new folder tools to Android SDK Folder like this image:
You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:
render: function() {
return (
<span>
// This will go through all the elements in arrayFromJson and
// render each one as a <SomeComponent /> with data from the object
{this.state.arrayFromJson.map(function(object) {
return (
<SomeComponent key={object.id} data={object} />
);
})}
</span>
);
}
if using homebrew you can update sim links using

This is for Bootstrap 4.0, you only need to enter selected on the first line, it acts as a placeholder. The values are not necessary, but if you want to add value 0-... that is up to you. Much simpler than you may think:
<select class="custom-select">
<option selected>Open This</option>
<option value="">1st Choice</option>
<option value="">2nd Choice</option>
</select>
Just go to Publish -> Application File -> And change the effected dll publish status from prerequisite to include! This worked for me!
To view console while debugging your chrome extension, you should use the chrome.extension.getBackgroundPage();
API, after that you can use console.log()
as usual:
chrome.extension.getBackgroundPage().console.log('Testing');
This is good when you use multiple time, so for that you create custom function:
const console = {
log: (info) => chrome.extension.getBackgroundPage().console.log(info),
};
console.log("foo");
you only use console.log('learnin')
everywhere
Register asp.net again....will solve the issue.
Go to Visual Studio Command Prompt,
And register asp.net as windows\microsoft.net\Framework[.Net version num]\aspnet_regiis.exe -i
For problems where it seems to be an error on a line you think is correct, you can often remove/comment the line where the error appears to be and, if the error moves to the next line, there are two possibilities.
Either both lines have a problem or the previous line has a problem which is being carried forward. The most likely case is the second option (even more so if you remove another line and it moves again).
For example, the following Python program twisty_passages.py
:
xyzzy = (1 +
plugh = 7
generates the error:
File "twisty_passages.py", line 2
plugh = 7
^
SyntaxError: invalid syntax
despite the problem clearly being on line 1.
In your particular case, that is the problem. The parentheses in the line before your error line is unmatched, as per the following snippet:
# open parentheses: 1 2 3
# v v v
fi2=0.460*scipy.sqrt(1-(Tr-0.566)**2/(0.434**2)+0.494
# ^ ^
# close parentheses: 1 2
Depending on what you're trying to achieve, the solution may be as simple as just adding another closing parenthesis at the end, to close off the sqrt
function.
I can't say for certain since I don't recognise the expression off the top of my head. Hardly surprising if (assuming PSAT is the enzyme, and the use of the typeMolecule
identifier) it's to do with molecular biology - I seem to recall failing Biology consistently in my youth :-)
Assuming that create_time contains the time the order was created, and you want the 100 clients with the latest orders, you can:
create_time desc
ROWNUM
Query:
SELECT * FROM (
SELECT * FROM (
SELECT
id,
client_id,
create_time,
ROW_NUMBER() OVER(PARTITION BY client_id ORDER BY create_time DESC) rn
FROM order
)
WHERE rn=1
ORDER BY create_time desc
) WHERE rownum <= 100
UPDATE for Oracle 12c
With release 12.1, Oracle introduced "real" Top-N queries. Using the new FETCH FIRST...
syntax, you can also use:
SELECT * FROM (
SELECT
id,
client_id,
create_time,
ROW_NUMBER() OVER(PARTITION BY client_id ORDER BY create_time DESC) rn
FROM order
)
WHERE rn = 1
ORDER BY create_time desc
FETCH FIRST 100 ROWS ONLY)
According to the StyleCop Rules Documentation the ordering is as follows.
Within a class, struct or interface: (SA1201 and SA1203)
Within each of these groups order by access: (SA1202)
Within each of the access groups, order by static, then non-static: (SA1204)
Within each of the static/non-static groups of fields, order by readonly, then non-readonly : (SA1214 and SA1215)
An unrolled list is 130 lines long, so I won't unroll it here. The methods part unrolled is:
The documentation notes that if the prescribed order isn't suitable - say, multiple interfaces are being implemented, and the interface methods and properties should be grouped together - then use a partial class to group the related methods and properties together.

iUsedRows = wksCur.UsedRange.Row + wksCur.UsedRange.Rows.Count - 1
iUsedCols = wksCur.UsedRange.Column + wksCur.UsedRange.Columns.Count - 1
If iUsedRows > iFirstRow And iUsedCols > iFirstCol Then

Invoke mysql with the -N
(the alias for -N
is --skip-column-names
) option:
mysql -N ...
use testdb;
select * from names;
+------+-------+
| 1 | pete |
| 2 | john |
| 3 | mike |
+------+-------+
3 rows in set (0.00 sec)
Credit to ErichBSchulz for pointing out the -N alias.
To remove the grid (the vertical and horizontal lines) around the results use -s
(--silent
). Columns are separated with a TAB
character.
mysql -s ...
use testdb;
select * from names;
id name
1 pete
2 john
3 mike
To output the data with no headers and no grid just use both -s
and -N
.
mysql -sN ...
With bash 4.2 and newer you can use something like this to strip the trailing CR, which only uses bash built-ins:
if [[ "${str: -1}" == $'\r' ]]; then
str="${str:: -1}"
fi
The right answer is:
android {
....
....
sourceSets {
main.java.srcDirs += 'src/main/<YOUR DIRECTORY>'
}
}
Furthermore, if your external source directory is not under src/main
, you could use a relative path like this:
sourceSets {
main.java.srcDirs += 'src/main/../../../<YOUR DIRECTORY>'
}
We can add additional columns to DataFrame directly with below steps:
from pyspark.sql.functions import when
df = spark.createDataFrame([["amit", 30], ["rohit", 45], ["sameer", 50]], ["name", "age"])
df = df.withColumn("profile", when(df.age >= 40, "Senior").otherwise("Executive"))
df.show()
In case of one request parameter it is simplier to use mediainfo and its output formatting like this (for duration; answer in milliseconds)
mediainfo --Output="General;%Duration%" ~/work/files/testfiles/+h263_aac.avi
outputs
24840
You must be separate those classes which you want to remove by white space$('selector').removeClass('class1 class2');
Here's how I addressed this (using a MEAN derivative)
My variables:
{
NODE_ENV : development,
...
ui_varables {
var1: one,
var2: two
}
}
First I had to make sure that the necessary config variables were being passed. MEAN uses the node nconf package, and by default is set up to limit which variables get passed from the environment. I had to remedy that:
config/config.js:
original:
nconf.argv()
.env(['PORT', 'NODE_ENV', 'FORCE_DB_SYNC'] ) // Load only these environment variables
.defaults({
store: {
NODE_ENV: 'development'
}
});
after modifications:
nconf.argv()
.env('__') // Load ALL environment variables
// double-underscore replaces : as a way to denote hierarchy
.defaults({
store: {
NODE_ENV: 'development'
}
});
Now I can set my variables like this:
export ui_varables__var1=first-value
export ui_varables__var2=second-value
Note: I reset the "heirarchy indicator" to "__" (double underscore) because its default was ":", which makes variables more difficult to set from bash. See another post on this thread.
Now the jade part: Next the values need to be rendered, so that javascript can pick them up on the client side. A straightforward way to write these values to the index file. Because this is a one-page app (angular), this page is always loaded first. I think ideally this should be a javascript include file (just to keep things clean), but this is good for a demo.
app/controllers/index.js:
'use strict';
var config = require('../../config/config');
exports.render = function(req, res) {
res.render('index', {
user: req.user ? JSON.stringify(req.user) : "null",
//new lines follow:
config_defaults : {
ui_defaults: JSON.stringify(config.configwriter_ui).replace(/<\//g, '<\\/') //NOTE: the replace is xss prevention
}
});
};
app/views/index.jade:
extends layouts/default
block content
section(ui-view)
script(type="text/javascript").
window.user = !{user};
//new line here
defaults = !{config_defaults.ui_defaults};
In my rendered html, this gives me a nice little script:
<script type="text/javascript">
window.user = null;
defaults = {"var1":"first-value","var2:"second-value"};
</script>
From this point it's easy for angular to utilize the code.
I took what you had, and added another X-Testing

"X-Testing" : "testing"

};
$http.get("/test", config);

For me worked the following:
sudo gitlab-ctl stop
sudo gitlab-ctl start gitaly
sudo gitlab-rake gitlab:setup [type yes and let it finish]
sudo gitlab-ctl start
I am using:
gitlab_edition: "gitlab-ce"
gitlab_version: '12.4.0-ce.0.el7'
If you want to resize the text as opposed to the button, you can use ...
button.titleLabel.adjustsFontSizeToFitWidth = YES;
button.titleLabel.minimumScaleFactor = .5;
// The .5 value means that I will let it go down to half the original font size
// before the texts gets truncated
// note, if using anything pre ios6, you would use I think
button.titleLabel.minimumFontSize = 8;
This is sample and best way for showing badge on notification launcher icon.

==> MyGcmListenerService.java Use BadgeUtils class when notification comes.
public class MyGcmListenerService extends GcmListenerService {
private static final String TAG = "MyGcmListenerService";
@Override
public void onMessageReceived(String from, Bundle data) {
String message = data.getString("Msg");
String Type = data.getString("Type");
Intent intent = new Intent(this, SplashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.BigTextStyle bigTextStyle= new NotificationCompat.BigTextStyle();
bigTextStyle .setBigContentTitle(getString(R.string.app_name))
.bigText(message);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(getNotificationIcon())
.setContentTitle(getString(R.string.app_name))
.setContentText(message)
.setStyle(bigTextStyle)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
int color = getResources().getColor(R.color.appColor);
notificationBuilder.setColor(color);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
int unOpenCount=AppUtill.getPreferenceInt("NOTICOUNT",this);
unOpenCount=unOpenCount+1;
AppUtill.savePreferenceLong("NOTICOUNT",unOpenCount,this);
notificationManager.notify(unOpenCount /* ID of notification */, notificationBuilder.build());
// This is for bladge on home icon
BadgeUtils.setBadge(MyGcmListenerService.this,(int)unOpenCount);
}
private int getNotificationIcon() {
boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP);
return useWhiteIcon ? R.drawable.notification_small_icon : R.drawable.icon_launcher;
}
}
And clear notification from preference and also with badge count
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
AppUtill.savePreferenceLong("NOTICOUNT",0,this);
BadgeUtils.clearBadge(this);
}
}

SELECT CONVERT(DATETIME, CONVERT(varchar(10), GETDATE(), 101))
also, I had this problem but the bib file wouldn't recompile. I removed the problem, which was an underscore in the note field, and compiled the tex file again, but kept getting the same errors. In the end I del'd the compiled bib file (.bbl I think) and it worked fine. I had to escape the _ using a backslash.
I had the same problem. I solve it when I convert string to factor. In your case, check the class of variable and check if they are numeric and 'train and test' should be factor.
Weirdly, I found that REMOVING &characterEncoding=UTF-8
from the JDBC url
did the trick for me with similar issues.
Based on my properties,
jdbc_url=jdbc:mysql://localhost:3306/dbName?useUnicode=true
I think this supports what @Esailija has said above, i.e. my MySQL, which is indeed 5.5, is figuring out its own favorite flavor of UTF-8 encoding.
(Note, I'm also specifying the InputStream
I'm reading from as UTF-8
in the java code, which probably doesn't hurt)...
this work for me, thanks. I want change text size only not change font name.
var fontSizeButtonBig:Int = 30
btnMenu9.titleLabel?.font = .systemFont(ofSize: CGFloat(fontSizeButtonBig))
You can write your native or non-native query the way you want, and you can wrap JPQL query results with instances of custom result classes. Create a DTO with the same names of columns returned in query and create an all argument constructor with same sequence and names as returned by the query. Then use following way to query the database.
@Query("SELECT NEW example.CountryAndCapital(c.name, c.capital.name) FROM Country AS c")
Create DTO:
package example;
public class CountryAndCapital {
public String countryName;
public String capitalName;
public CountryAndCapital(String countryName, String capitalName) {
this.countryName = countryName;
this.capitalName = capitalName;
}
}
What you need to do is to call pthread_mutex_lock to secure a mutex, like this:
pthread_mutex_lock(&mutex);
Once you do this, any other calls to pthread_mutex_lock(mutex)
will not return until you call pthread_mutex_unlock
in this thread. So if you try to call pthread_create, you will be able to create a new thread, and that thread will be able to (incorrectly) use the shared resource. You should call pthread_mutex_lock
from within your fooAPI
function, and that will cause the function to wait until the shared resource is available.
So you would have something like this:
#include <pthread.h>
#include <stdio.h>
int sharedResource = 0;
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;
void* fooAPI(void* param)
{
pthread_mutex_lock(&mutex);
printf("Changing the shared resource now.\n");
sharedResource = 42;
pthread_mutex_unlock(&mutex);
return 0;
}
int main()
{
pthread_t thread;
// Really not locking for any reason other than to make the point.
pthread_mutex_lock(&mutex);
pthread_create(&thread, NULL, fooAPI, NULL);
sleep(1);
pthread_mutex_unlock(&mutex);
// Now we need to lock to use the shared resource.
pthread_mutex_lock(&mutex);
printf("%d\n", sharedResource);
pthread_mutex_unlock(&mutex);
}
Edit: Using resources across processes follows this same basic approach, but you need to map the memory into your other process. Here's an example using shmem:
#include <stdio.h>
#include <unistd.h>
#include <sys/file.h>
#include <sys/mman.h>
#include <sys/wait.h>
struct shared {
pthread_mutex_t mutex;
int sharedResource;
};
int main()
{
int fd = shm_open("/foo", O_CREAT | O_TRUNC | O_RDWR, 0600);
ftruncate(fd, sizeof(struct shared));
struct shared *p = (struct shared*)mmap(0, sizeof(struct shared),
PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
p->sharedResource = 0;
// Make sure it can be shared across processes
pthread_mutexattr_t shared;
pthread_mutexattr_init(&shared);
pthread_mutexattr_setpshared(&shared, PTHREAD_PROCESS_SHARED);
pthread_mutex_init(&(p->mutex), &shared);
int i;
for (i = 0; i < 100; i++) {
pthread_mutex_lock(&(p->mutex));
printf("%d\n", p->sharedResource);
pthread_mutex_unlock(&(p->mutex));
sleep(1);
}
munmap(p, sizeof(struct shared*));
shm_unlink("/foo");
}
Writing the program to make changes to p->sharedResource is left as an exercise for the reader. :-)
Forgot to note, by the way, that the mutex has to have the PTHREAD_PROCESS_SHARED attribute set, so that pthreads will work across processes.
For this case you can also sort using LINQ:
week = week.OrderBy(w => DateTime.Parse(w.date)).ToList();
It maybe solve your problem, check your files access level
$ sudo chmod -R 777 /"your files location"
I'd simply import the moment module, then use a computed function to handle my moment() logic and return a value that's referenced in the template.
While I have not used this and thus can not speak on it's effectiveness, I did find https://github.com/brockpetrie/vue-moment for an alternate consideration
Also good to check is telephony supported on device
private boolean isTelephonyEnabled(){
TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
return tm != null && tm.getSimState()==TelephonyManager.SIM_STATE_READY
}
UPDATE: I've since changed my mind on this solution. After more development and time spent working on this, I believe a better solution to this problem is to do the following:
<a ng-click="myFunction()">Click Here</a>
And then update your css
to have an extra rule:
a[ng-click]{
cursor: pointer;
}
Its much more simple and provides the exact same functionality and is much more efficient. Hope that might be helpful to anyone else looking up this solution in the future.
The following is my previous solution, which I am leaving here just for legacy purposes:
If you are having this problem a lot, a simple directive that would fix this issue is the following:
app.directive('a', function() {
return {
restrict: 'E',
link: function(scope, elem, attrs) {
if(attrs.ngClick || attrs.href === '' || attrs.href === '#'){
elem.on('click', function(e){
e.preventDefault();
});
}
}
};
});
It checks all anchor tags (<a></a>
) to see if their href
attribute is either an empty string (""
) or a hash ('#'
) or there is an ng-click
assignment. If it finds any of these conditions, it catches the event and prevents the default behavior.
The only down side is that it runs this directive for all anchor tags. So if you have a lot of anchor tags on the page and you only want to prevent the default behavior for a small number of them, then this directive isn't very efficient. However, I almost always want to preventDefault
, so I use this directive all over in my AngularJS apps.
Try following int git bash
1.git add -u :/
2.git commit -m "your commit message"
git push -u origin master
Note:if you have not initialized your repo.
First of all
git init
and follow above mentioned steps in order. This worked for me
You can also provide a negative number as an argument to the round
method to round to the nearest multiple of 10, 100 and so on.
# Round to the nearest multiple of 10.
12.3453.round(-1) # Output: 10
# Round to the nearest multiple of 100.
124.3453.round(-2) # Output: 100
File modification:
ls -t
Inode change:
ls -tc
File access:
ls -tu
"Newest" one at the bottom:
ls -tr
None of this is a creation time. Most Unix filesystems don't support creation timestamps.
With an Android-powered device, you can develop and debug your Android applications just as you would on the emulator.
1. Declare your application as "debuggable" in AndroidManifest.xml
.
<application
android:debuggable="true"
... >
...
</application>
2. On your handset, navigate to Settings > Security and check Unknown sources
3. Go to Settings > Developer Options and check USB debugging
Note that if Developer Options
is invisible you will need to navigate to Settings > About Phone and tap on Build number
several times until you are notified that it has been unlocked.
4. Set up your system to detect your device.
Follow the instructions below for your OS:
Install the Google USB Driver from the ADT SDK Manager
(Support for: ADP1, ADP2, Verizon Droid, Nexus One, Nexus S).
For devices not listed above, install an OEM driver for your device
Your device should automatically work; Go to the next step
Add a udev
rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, click here. To set up device detection on Ubuntu Linux:
/etc/udev/rules.d/51-android.rules
.SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
chmod a+r /etc/udev/rules.d/51-android.rules
Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules.
5. Run the project with your connected device.
With Eclipse/ADT: run or debug your application as usual. You will be presented with a Device Chooser dialog that lists the available emulator(s) and connected device(s).
With ADB: issue commands with the -d flag to target your connected device.

You can validate group checkbox and radio button without extra js code, see below example.
Your JS should be look like:
$("#formid").validate();
You can play with HTML tag and attributes: eg. group checkbox [minlength=2 and maxlength=4]
<fieldset class="col-md-12">
<legend>Days</legend>
<div class="form-row">
<div class="col-12 col-md-12 form-group">
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="1" required="required" data-msg-required="This value is required." minlength="2" maxlength="4" data-msg-maxlength="Max should be 4">Monday
</label>
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="2">Tuesday
</label>
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="3">Wednesday
</label>
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="4">Thursday
</label>
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="5">Friday
</label>
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="6">Saturday
</label>
<label class="checkbox-inline">
<input type="checkbox" name="daysgroup[]" value="7">Sunday
</label>
<label for="daysgroup[]" class="error">Your error message will be display here.</label>
</div>
</div>
</fieldset>
You can see here first or any one input should have required, minlength="2" and maxlength="4" attributes. minlength/maxlength as per your requirement.
eg. group radio button:
<fieldset class="col-md-12">
<legend>Gender</legend>
<div class="form-row">
<div class="col-12 col-md-12 form-group">
<label class="form-check-inline">
<input type="radio" name="gendergroup[]" value="m" required="required" data-msg-required="This value is required.">man
</label>
<label class="form-check-inline">
<input type="radio" name="gendergroup[]" value="w">woman
</label>
<label class="form-check-inline">
<input type="radio" name="gendergroup[]" value="o">other
</label>
<label for="gendergroup[]" class="error">Your error message will be display here.</label>
</div>
</div>
</fieldset>
You can check working example here.
use this and it works on both the static arrays and dynamically generated arrays.
var array = [12,2,23,324,23,123,4,23,132,23];
var getMaxValue = Math.max.apply(Math, array );
I had the issue when I use trying to find max value from code below
$('#myTabs').find('li.active').prevAll().andSelf().each(function () {
newGetWidthOfEachTab.push(parseInt($(this).outerWidth()));
});
for (var i = 0; i < newGetWidthOfEachTab.length; i++) {
newWidthOfEachTabTotal += newGetWidthOfEachTab[i];
newGetWidthOfEachTabArr.push(parseInt(newWidthOfEachTabTotal));
}
getMaxValue = Math.max.apply(Math, array);
I was getting 'NAN'
when I use
var max_value = Math.max(12, 21, 23, 2323, 23);
with my code
process.mainModule
is deprecated since v 14.0.0. When referring to the answer, please userequire.main
, the rest still holds.
process.mainModule.paths
.filter(p => !p.includes('node_modules'))
.shift()
Get all paths in main modules and filter out those with "node_modules",
then get the first of remaining path list. Unexpected behavior will not throw error, just an undefined
.
Works well for me, even when calling ie $ mocha
.
Create an object literal:
const Modes = {
DRAGGING: 'drag',
SCALING: 'scale',
CLICKED: 'click'
};
