Use pyplot.suptitle
or Figure.suptitle
:
import matplotlib.pyplot as plt
import numpy as np
fig=plt.figure()
data=np.arange(900).reshape((30,30))
for i in range(1,5):
ax=fig.add_subplot(2,2,i)
ax.imshow(data)
fig.suptitle('Main title') # or plt.suptitle('Main title')
plt.show()
I would just use the request.remote_ip
that's simple and it works. Any reason you need another method?

Thought I'd share this code. It's fairly simple, but effective. It parses comma-separated files with parenthesis. You can easily modify it to suit your needs.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[])
{
//argv[1] path to csv file
//argv[2] number of lines to skip
//argv[3] length of longest value (in characters)
FILE *pfinput;
unsigned int nSkipLines, currentLine, lenLongestValue;
char *pTempValHolder;
int c;
unsigned int vcpm; //value character marker
int QuotationOnOff; //0 - off, 1 - on
nSkipLines = atoi(argv[2]);
lenLongestValue = atoi(argv[3]);
pTempValHolder = (char*)malloc(lenLongestValue);
if( pfinput = fopen(argv[1],"r") ) {
rewind(pfinput);
currentLine = 1;
vcpm = 0;
QuotationOnOff = 0;
//currentLine > nSkipLines condition skips ignores first argv[2] lines
while( (c = fgetc(pfinput)) != EOF)

switch(c)

I experienced a similar issue.
Here's how I solved it
Run the service command below to start ElasticSearch
sudo service elasticsearch start
OR
sudo systemctl start elasticsearch
If you still get the error
curl: (7) Failed to connect to localhost port 9200: Connection refused
Run the service command below to check the status of ElasticSearch
sudo service elasticsearch status
OR
sudo systemctl status elasticsearch
If you get a response (Active: active (running)) like the one below then you ElasticSearch is active and running
? elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled) Active: active (running) since Sat 2019-09-21 11:22:21 WAT; 3s ago
You can then test that your Elasticsearch node is running by sending an HTTP request to port 9200 on localhost using the command below:
curl http://localhost:9200
Else, if you get a response a different response, you may have to debug further to fix it, but the running the command below, will help you detect what caveats are holding ElasticSearch service from starting.
sudo service elasticsearch status
OR
sudo systemctl status elasticsearch
If you want to stop the ElasticSearch service, simply run the service command below;
sudo service elasticsearch stop
OR
sudo systemctl stop elasticsearch
N/B: You may have to run the command sudo service elasticsearch status
OR sudo systemctl status elasticsearch
each time you encounter the error, in order to tell the state of the ElasticSearch service.
This also applies for Kibana, run the command sudo service kibana status
OR sudo systemctl status kibana
each time you encounter the error, in order to tell the state of the Kibana service.
That's all.
I hope this helps.
Probably the easiest solution so far:
public static Bitmap cropCenter(Bitmap bmp) {
int dimension = Math.min(bmp.getWidth(), bmp.getHeight());
return ThumbnailUtils.extractThumbnail(bmp, dimension, dimension);
}
imports:
import android.media.ThumbnailUtils;
import java.lang.Math;
import android.graphics.Bitmap;
Ok...so first you need to import in your project the image
1)Select the picturebox in Form Design
2)Open PictureBox Tasks (it's the little arrow pinted to right on the edge on the picturebox)
3)Click on "Choose image..."
4)Select the second option "Project resource file:" (this option will create a folder called "Resources" which you can acces with Properties.Resources)
5)Click on import and select your image from your computer (now a copy of the image with the same name as the image will be sent in Resources folder created at step 4)
6)Click on ok
Now the image is in your project and you can use it with Properties command.Just type this code when you want to change the picture from picturebox:
pictureBox1.Image = Properties.Resources.myimage;
Note: myimage represent the name of the image...after typing the dot after Resources,in your options it will be your imported image file
I think your problem is that the match method is returning an array. The 0th item in the array is the original string, the 1st thru nth items correspond to the 1st through nth matched parenthesised items. Your "alert()" call is showing the entire array.
I want to point out that it has been my experience that if throwing an HttpResponseException instead of returning an HttpResponseMessage in a webapi 2 method, that if a call is made immediately to IIS Express it will timeout or return a 200 but with a html error in the response.
Easiest way to test this is to make $.ajax call to a method that throws a HttpResponseException and in the errorCallBack in ajax make an immediate call to another method or even a simple http page. You will notice the imediate call will fail. If you add a break point or a settimeout() in the error call back to delay the second call a second or two giving the server time to recover it works correctly. This makes no since but its almost like the throw HttpResponseException causes the server side listener thread to exit and restart causing a split second of no server accepting connections or something.
Update: The root cause of the wierd Ajax connection Timeout is if an ajax call is made quick enough the same tcp connection is used. I was raising a 401 error ether by returning a HttpResonseMessage or throwing a HTTPResponseException which was returned to the browser ajax call. But along with that call MS was returning a Object Not Found Error because in Startup.Auth.vb app.UserCookieAuthentication was enabled so it was trying to return intercept the response and add a redirect but it errored with Object not Instance of an Object. This Error was html but was appended to the response after the fact so only if the ajax call was made quick enough and the same tcp connection used did it get returned to the browser and then it got appended to the front of the next call. For some reason Chrome just timedout, fiddler pucked becasue of the mix of json and htm but firefox rturned the real error. So wierd but packet sniffer or firefox was the only way to track this one down.
Also it should be noted that if you are using Web API help to generate automatic help and you return HttpResponseMessage then you should add a
[System.Web.Http.Description.ResponseType(typeof(CustomReturnedType))]
attribute to the method so the help generates correctly. Then
return Request.CreateResponse<CustomReturnedType>(objCustomeReturnedType)
or on error
return Request.CreateErrorResponse( System.Net.HttpStatusCode.InternalServerError, new Exception("An Error Ocurred"));
Hope this helps someone else who may be getting random timeout or server not available immediately after throwing a HttpResponseException.
Also returning an HttpResponseException has the added benefit of not causing Visual Studio to break on an Un-handled exception usefull when the error being returned is the AuthToken needs to be refreshed in a single page app.
Update: I am retracting my statement about IIS Express timing out, this happened to be a mistake in my client side ajax call back it turns out since Ajax 1.8 returning $.ajax() and returning $.ajax.().then() both return promise but not the same chained promise then() returns a new promise which caused the order of execution to be wrong. So when the then() promise completed it was a script timeout. Weird gotcha but not an IIS express issue a problem between the Keyboard and chair.
Don't forget the option "-o", which lets you download anywhere you want, although you have to create "archives", "lock" and "partial" first (the command prints what's needed).

The Splatting Operator
To create an array, we create a variable and assign the array. Arrays are noted by the "@" symbol. Let's take the discussion above and use an array to connect to multiple remote computers:
$strComputers = @("Server1", "Server2", "Server3")<enter>
They are used for arrays and hashes.
if you want to get route name in your controller than you have to inject the request (instead of getting from container due to Symfony UPGRADE and than call get('_route').
public function indexAction(Request $request)
{
$routeName = $request->get('_route');
}
if you want to get route name in twig than you have to get it like
{{ app.request.attributes.get('_route') }}
The getElementById
method returns an Element object that you can use to interact with the element. If the element is not found, null
is returned. In case of an input element, the value
property of the object contains the string in the value attribute.
By using the fact that the &&
operator short circuits, and that both null
and the empty string are considered "falsey" in a boolean context, we can combine the checks for element existence and presence of value data as follows:
var myInput = document.getElementById("customx");
if (myInput && myInput.value) {
alert("My input has a value!");
}
You can also use extremely small numbers for your radius'.
<corners
android:bottomRightRadius="0.1dp" android:bottomLeftRadius="2dp"
android:topLeftRadius="2dp" android:topRightRadius="0.1dp" />
Unfortunately, (for practical and security reasons I guess), if you want to add/copy local content, it must be located under the same root path than the Dockerfile
.
From the documentation:
The <src> path must be inside the context of the build; you cannot ADD ../something/something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.
EDIT: There's now an option (-f
) to set the path of your Dockerfile ; it can be used to achieve what you want, see @Boedy 's response.
System.IO.MemoryStream mStream = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes( contents));
You need to set the g flag to replace globally:
date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')
Otherwise only the first occurrence will be replaced.
Have you copied classes12.jar in lib folder of your web application and set the classpath in eclipse.

Trying to run cleanup while your files are open gave me problems. as soon as I closed my application (Visual studio) I ran clean up and it was successful
This should do it
replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
with open('path/to/input/file') as infile, open('path/to/output/file', 'w') as outfile:
for line in infile:
for src, target in replacements.iteritems():
line = line.replace(src, target)
outfile.write(line)
EDIT: To address Eildosa's comment, if you wanted to do this without writing to another file, then you'll end up having to read your entire source file into memory:
lines = []
with open('path/to/input/file') as infile:
for line in infile:
for src, target in replacements.iteritems():
line = line.replace(src, target)
lines.append(line)
with open('path/to/input/file', 'w') as outfile:
for line in lines:
outfile.write(line)
Edit: If you are using Python 3.x, use replacements.items()
instead of replacements.iteritems()
Though you can't add a key pair to a running EC2 instance directly, you can create a linux user and create a new key pair for him, then use it like you would with the original user's key pair.
In your case, you can ask the instance owner (who created it) to do the following. Thus, the instance owner doesn't have to share his own keys with you, but you would still be able to ssh into these instances. These steps were originally posted by Utkarsh Sengar (aka. @zengr) at http://utkarshsengar.com/2011/01/manage-multiple-accounts-on-1-amazon-ec2-instance/. I've made only a few small changes.
Step 1: login by default “ubuntu” user:
$ ssh -i my_orig_key.pem [email protected]
Step 2: create a new user, we will call our new user “john”:
[ubuntu@ip-11-111-111-111 ~]$ sudo adduser john
Set password for “john” by:
[ubuntu@ip-11-111-111-111 ~]$ sudo su -
[root@ip-11-111-111-111 ubuntu]# passwd john
Add “john” to sudoer’s list by:
[root@ip-11-111-111-111 ubuntu]# visudo
.. and add the following to the end of the file:
john ALL = (ALL) ALL
Alright! We have our new user created, now you need to generate the key file which will be needed to login, like we have my_orin_key.pem in Step 1.
Now, exit and go back to ubuntu, out of root.
[root@ip-11-111-111-111 ubuntu]# exit
[ubuntu@ip-11-111-111-111 ~]$
Step 3: creating the public and private keys:
[ubuntu@ip-11-111-111-111 ~]$ su john
Enter the password you created for “john” in Step 2. Then create a key pair. Remember that the passphrase for key pair should be at least 4 characters.
[john@ip-11-111-111-111 ubuntu]$ cd /home/john/
[john@ip-11-111-111-111 ~]$ ssh-keygen -b 1024 -f john -t dsa
[john@ip-11-111-111-111 ~]$ mkdir .ssh
[john@ip-11-111-111-111 ~]$ chmod 700 .ssh
[john@ip-11-111-111-111 ~]$ cat john.pub > .ssh/authorized_keys
[john@ip-11-111-111-111 ~]$ chmod 600 .ssh/authorized_keys
[john@ip-11-111-111-111 ~]$ sudo chown john:ubuntu .ssh
In the above step, john is the user we created and ubuntu is the default user group.
[john@ip-11-111-111-111 ~]$ sudo chown john:ubuntu .ssh/authorized_keys
Step 4: now you just need to download the key called “john”. I use scp to download/upload files from EC2, here is how you can do it.
You will still need to copy the file using ubuntu user, since you only have the key for that user name. So, you will need to move the key to ubuntu folder and chmod it to 777.
[john@ip-11-111-111-111 ~]$ sudo cp john /home/ubuntu/
[john@ip-11-111-111-111 ~]$ sudo chmod 777 /home/ubuntu/john
Now come to local machine’s terminal, where you have my_orig_key.pem file and do this:
$ cd ~/.ssh
$ scp -i my_orig_key.pem [email protected]:/home/ubuntu/john john
The above command will copy the key “john” to the present working directory on your local machine. Once you have copied the key to your local machine, you should delete “/home/ubuntu/john”, since it’s a private key.
Now, one your local machine chmod john to 600.
$ chmod 600 john
Step 5: time to test your key:
$ ssh -i john [email protected]
So, in this manner, you can setup multiple users to use one EC2 instance!!
This is also a possible workaround, but you will have to go through your css and add a .no-touch
class before your hover styles.
Javascript:
if (!("ontouchstart" in document.documentElement)) {
document.documentElement.className += " no-touch";
}
CSS Example:
<style>
p span {
display: none;
}
.no-touch p:hover span {
display: inline;
}
</style>
<p><a href="/">Tap me</a><span>You tapped!</span></p>
P.s. But we should remember, there are coming more and more touch-devices to the market, which are also supporting mouse input at the same time.
Note that there is an unrelated issue in your code but that could bite you later: you should return res.json()
or you will not catch any error occurring in JSON parsing or your own function processing data.
Back to your error: You cannot have a TypeError: failed to fetch
with a successful request. You probably have another request (check your "network" panel to see all of them) that breaks and causes this error to be logged. Also, maybe check "Preserve log" to be sure the panel is not cleared by any indelicate redirection. Sometimes I happen to have a persistent "console" panel, and a cleared "network" panel that leads me to have error in console which is actually unrelated to the visible requests. You should check that.
Or you (but that would be vicious) actually have a hardcoded console.log('TypeError: failed to fetch')
in your final .catch
;) and the error is in reality in your .then()
but it's hard to believe.

read
reads until it finds a newline character or the end of file, and returns a non-zero exit code if it encounters an end-of-file. So it's quite possible for it to both read a line and return a non-zero exit code.
Consequently, the following code is not safe if the input might not be terminated by a newline:
while read LINE; do
# do something with LINE
done
because the body of the while
won't be executed on the last line.
Technically speaking, a file not terminated with a newline is not a text file, and text tools may fail in odd ways on such a file. However, I'm always reluctant to fall back on that explanation.
One way to solve the problem is to test if what was read is non-empty (-n
):
while read -r LINE || [[ -n $LINE ]]; do
# do something with LINE
done
Other solutions include using mapfile
to read the file into an array, piping the file through some utility which is guaranteed to terminate the last line properly (grep .
, for example, if you don't want to deal with blank lines), or doing the iterative processing with a tool like awk
(which is usually my preference).
Note that -r
is almost certainly needed in the read
builtin; it causes read
to not reinterpret \
-sequences in the input.
Yes, session doesn't go hand in hand with Rest API and also we should avoid this practices. But as per requirements we need to maintain session somehow such that in every request client server can exchange or maintain state or data. So, the best way to achieve this without breaking the REST protocols is communicate through token like JWT.
Try this code :)
Its an fully transparent hex code - "#00000000"
You will need to get a DateTime
object from your TimeSpan
and then you can format it easily.
One possible solution is adding the timespan to any date with zero time value.
var timespan = new TimeSpan(3, 0, 0);
var output = new DateTime().Add(timespan).ToString("hh:mm tt");
The output value will be "03:00 AM"
(for english locale).

Looks like the path you gave doesn't have any bootstrap files in them.

Make sure the files exist over there , else point the files to the correct path, which should be in your case

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -
, like script.ps1 -server http://devserver
Then you handle them in param
section in the beginning of the file.
You can also assign default values to your params, read them from console if not available or stop script execution:
param (
[string]$server = "http://defaultserver",
[Parameter(Mandatory=$true)][string]$username,
[string]$password = $( Read-Host "Input password, please" )
)
Inside the script you can simply
write-output $server
since all parameters become variables available in script scope.
In this example, the $server
gets a default value if the script is called without it, script stops if you omit the -username
parameter and asks for terminal input if -password
is omitted.
Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.
The keyword for that is [switch]
parameter type:
param (
[string]$server = "http://defaultserver",
[string]$password = $( Read-Host "Input password, please" ),
[switch]$force = $false
)
Inside the script then you would work with it like this:
if ($force) {
//deletes a file or does something "bad"
}
Now, when calling the script you'd set the switch/flag parameter like this:
.\yourscript.ps1 -server "http://otherserver" -force
If you explicitly want to state that the flag is not set, there is a special syntax for that
.\yourscript.ps1 -server "http://otherserver" -force:$false
Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):
I don't know why
cfg_name_unique NOT LIKE '%categories%'
still returns those two values, but maybe exclude them explicit:
SELECT *
FROM developer_configurations_cms
WHERE developer_configurations_cms.cat_id = '1'
AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%'
AND developer_configurations_cms.cfg_name_unique NOT IN ('categories_posts', 'categories_news')
Quite simply:
A procedure can't return a table as such. However you can select from a table in a procedure and direct it into a table (or table variable) like this:
create procedure p_x
as
begin
declare @t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert @t values('a', 1,1,1)
insert @t values('b', 2,2,2)
select * from @t
end
go
declare @t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert @t
exec p_x
select * from @t
I'm didn't totally follow, but to add an action listener, you just call addActionListener (from Abstract Button). If this doesn't totally answer your question, can you provide some more details?
The Revert command in the context menu ignores your edits and returns the working copy to its previous state. You may also select the desired revision other than the "Head" when you "CheckOut" from the repository.
A web application is a website in the same way that a square is a rectangle.
The application part is the model-controller combo. The web part (the view) is why it qualifies as a website.
Something that is only a website and not a web application is simply missing the dynamic aspect.
Of course, it can be difficult to decide on how much server-side processing is required to qualify it as a web application. Probably when it has a data store.
Thus, you have the primary role of webapps confused. A website's primary role is to inform. A web app's primary role is to inform using dynamic content (the do something part).
Are they just saying don't use session/application level data store???
No. They aren't saying that in a trivial way.
They're saying do not define a "session". Don't login. Don't logout. Provide credentials with the request. Each request stands alone.
You still have data stores. You still have authentication and authorization. You just don't waste time establishing sessions and maintaining session state.
The point is that each request (a) stands completely alone and (b) can be trivially farmed out to a giant parallel server farm without any actual work. Apache or Squid can pass RESTful requests around blindly and successfully.
What if I had a queue of messages, and my user wanted to read the messages, but as he read them, wanted to block certain senders messages coming through for the duration of his session?
If the user wants a filter, then simply provide the filter on each request.
Wouldn't it make sense to ... have the server only send messages (or message ID's) that were not blocked by the user?
Yes. Provide the filter in the RESTful URI request.
Do I really have to send the entire list of message senders to block each time I request the new message list?
Yes. How big can this "list of message senders to block" be? A short list of PK's?
A GET request can be very large. If necessary, you can try a POST request even though it sounds like a kind of query.
Switch in itself isn't that bad, but if you have lots of "switch" or "if/else" on objects in your methods it may be a sign that your design is a bit "procedural" and that your objects are just value buckets. Move the logic to your objects, invoke a method on your objects and let them decide how to respond instead.
What do you want to fade? The background
or color
attribute?
Currently you're changing the background color, but telling it to transition the color property. You can use all
to transition all properties.
.clicker {
-moz-transition: all .2s ease-in;
-o-transition: all .2s ease-in;
-webkit-transition: all .2s ease-in;
transition: all .2s ease-in;
background: #f5f5f5;
padding: 20px;
}
.clicker:hover {

Your regexp seems to validate both the file name and the extension. Is that what you need? I'll assume it's just the extension and would use a regexp like this:
\.(jpg|gif|doc|pdf)$
And set the matching to be case insensitive.
There are so many ways you can accomplish this. Here's some I did:
Generates six random hex digits (0-F)
function randColor() {
for (var i=0, col=''; i<6; i++) {
col += (Math.random()*16|0).toString(16);
}
return '#'+col;
}
Extremely short one-liner
'#'+(Math.random().toString(16)+'00000').slice(2,8)
Generates individual HEX components (00-FF)
function randColor2() {
var r = ('0'+(Math.random()*256|0).toString(16)).slice(-2),
g = ('0'+(Math.random()*256|0).toString(16)).slice(-2),
b = ('0'+(Math.random()*256|0).toString(16)).slice(-2);
return '#' +r+g+b;
}
Over-engineered hex string (XORs 3 outputs together to form color)
function randColor3() {
var str = Math.random().toString(16) + Math.random().toString(16),
sg = str.replace(/0./g,'').match(/.{1,6}/g),
col = parseInt(sg[0], 16) ^
parseInt(sg[1], 16) ^
parseInt(sg[2], 16);
return '#' + ("000000" + col.toString(16)).slice(-6);
}
You can use the spool
command (SQL*Plus documentation, but one of many such commands SQL Developer also supports) to write results straight to disk. Each spool
can change the file that's being written to, so you can have several queries writing to different files just by putting spool
commands between them:
spool "\path\to\spool1.txt"
select /*csv*/ * from employees;
spool "\path\to\spool2.txt"
select /*csv*/ * from locations;
spool off;
You'd need to run this as a script (F5, or the second button on the command bar above the SQL Worksheet). You might also want to explore some of the formatting options and the set
command, though some of those do not translate to SQL Developer.
Since you mentioned CSV in the title I've included a SQL Developer-specific hint that does that formatting for you.
A downside though is that SQL Developer includes the query in the spool file, which you can avoid by having the commands and queries in a script file that you then run as a script.
I used fontWithSize
for a label with light system font, but it changes back to normal system font.
If you want to keep the font's traits, better to include the descriptors.
label.font = UIFont(descriptor: label.font.fontDescriptor(), size: 16.0)
In this case you are restarting your node.js server often because it's in active development and you are making changes all the time. There is a great hot reload script that will handle this for you by watching all your .js files and restarting your node.js server if any of those files have changed. Just the ticket for rapid development and test.
The script and explanation on how to use it are at here at Draco Blue.
You can use the Build Class to get the device information.
For example:
String myDeviceModel = android.os.Build.MODEL;
You can get free Virtual Machine and many more things online for 3 months provided by Microsoft Azure. I guess you need VPN for learning purpose. For that it would suffice.
I found one way to access the shared folder without giving the username and password.
We need to change the share folder protect settings in the machine where the folder has been shared.
Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.
By doing the above settings we can access the shared folder without any username/password.
You can't use shorthand notation to set configuration values outside of PHP.ini. I assume it's falling back to 2MB as the compiled default when confronted with a bad value.
On the other hand, I don't think upload_max_filesize
could be set using ini_set()
. The "official" list states that it is PHP_INI_PERDIR
.
Plenty of responses already, but you can use this:
Sub runQry(qDefName)
Dim db As DAO.Database, qd As QueryDef, par As Parameter
Set db = CurrentDb
Set qd = db.QueryDefs(qDefName)
On Error Resume Next
For Each par In qd.Parameters
Err.Clear
par.Value = Eval(par.Name) 'try evaluating param
If Err.Number <> 0 Then 'failed ?
par.Value = InputBox(par.Name) 'ask for value
End If
Next par
On Error GoTo 0
qd.Execute dbFailOnError
End Sub
Sub runQry_test()
runQry "test" 'qryDef name
End Sub
This solution meets the following criteria
As far as I'm aware, this criteria cannot be met without Javascript (unfortunately).
This solution uses jQuery, but could also be easily converted to vanilla JS:
function fixedHeader(){_x000D_
$(this).width($("#wrapper").width());_x000D_
$("#header-filler").height($("#header-fixed").outerHeight());_x000D_

var twitterObject = JToken.Parse(jsonString);
var trendsArray = twitterObject.Children<JProperty>().FirstOrDefault(x => x.Name == "trends").Value;
foreach (var item in trendsArray.Children())

So call Children on your JArray to get each JObject in JArray. Call Children on each JObject to access the objects properties.
foreach(var item in yourJArray.Children())
{
var itemProperties = item.Children<JProperty>();
//you could do a foreach or a linq here depending on what you need to do exactly with the value

Since Bootstrap 3 you have to use checkbox-inline and radio-inline classes on the label.
This takes care of vertical alignment.
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
prods.Remove(prods.Find(x => x.ID == 1));
Below is how I got this working.
The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.
[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]
[HttpPost]
public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)
{
var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
}
The JQuery script used to call this action method:
var requestData = {
InvoiceNumber: $.trim(this.value),
SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
};
$.ajax({
url: '/en/myController/GetDataForInvoiceNumber',
type: 'POST',
data: JSON.stringify(requestData),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
CheckIfInvoiceFound(result);
},
async: true,
processData: false
});

I generally first try .inspect
, if that doesn't give me what I want, I'll switch to .to_yaml
.
class User
attr_accessor :name, :age
end
user = User.new
user.name = "John Smith"
user.age = 30
puts user.inspect
#=> #<User:0x423270c @name="John Smith", @age=30>
puts user.to_yaml
#=> --- !ruby/object:User
#=> age: 30
#=> name: John Smith
Hope that helps.
Use nssm.exe but remember to set the AppDirectory or any required libraries or resources will not be accessible. By default nssm set the current working directory to the that of the application, java.exe, not the jar. So do this to create a batch script:
pushd <path-to-jar>
nssm.exe install "<service-name>" "<path-to-java.exe>" "-jar <name-of-jar>"
nssm.exe set "<service-name>" AppDirectory "<path-to-jar>"
This should fix the service paused issue.
There's a very simple answer to this: Profile the performance of your web server to see what the performance penalty is for your particular situation. There are several tools out there to compare the performance of an HTTP vs HTTPS server (JMeter and Visual Studio come to mind) and they are quite easy to use.
No one can give you a meaningful answer without some information about the nature of your web site, hardware, software, and network configuration.
As others have said, there will be some level of overhead due to encryption, but it is highly dependent on:
In my experience, servers that are heavy on dynamic content tend to be impacted less by HTTPS because the time spent encrypting (SSL-overhead) is insignificant compared to content generation time.
Servers that are heavy on serving a fairly small set of static pages that can easily be cached in memory suffer from a much higher overhead (in one case, throughput was havled on an "intranet").
Edit: One point that has been brought up by several others is that SSL handshaking is the major cost of HTTPS. That is correct, which is why "typical session length" and "caching behavior of clients" are important.
Many, very short sessions means that handshaking time will overwhelm any other performance factors. Longer sessions will mean the handshaking cost will be incurred at the start of the session, but subsequent requests will have relatively low overhead.
Client caching can be done at several steps, anywhere from a large-scale proxy server down to the individual browser cache. Generally HTTPS content will not be cached in a shared cache (though a few proxy servers can exploit a man-in-the-middle type behavior to achieve this). Many browsers cache HTTPS content for the current session and often times across sessions. The impact the not-caching or less caching means clients will retrieve the same content more frequently. This results in more requests and bandwidth to service the same number of users.
In the specific case of x68 to x68_64, the 64 bit program will be about the same size, if not slightly smaller, use a bit more memory, and run faster. Mostly this is because x86_64 doesn't just have 64 bit registers, it also has twice as many. x86 does not have enough registers to make compiled languages as efficient as they could be, so x86 code spends a lot of instructions and memory bandwidth shifting data back and forth between registers and memory. x86_64 has much less of that, and so it takes a little less space and runs faster. Floating point and bit-twiddling vector instructions are also much more efficient in x86_64.
In general, though, 64 bit code is not necessarily any faster, and is usually larger, both for code and memory usage at runtime.
If the string is at the beginning of the name, you can do this
$ compgen -f .bash
.bashrc
.bash_profile
.bash_prompt
Actually the easiest way to change (only) port in development Django server is just like:
python manage.py runserver 7000
that should run development server on http://127.0.0.1:7000/
This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row)
and check how many indexes there exists.
You should know that it is not possible to directly run a DDL statement like you do for DML from a PL/SQL block because PL/SQL does not support late binding directly it only support compile time binding which is fine for DML. hence to overcome this type of problem oracle has provided a dynamic SQL approach which can be used to execute the DDL statements.The dynamic sql approach is about parsing and binding of sql string at the runtime. Also you should rememder that DDL statements are by default auto commit hence you should be careful about any of the DDL statement using the dynamic SQL approach incase if you have some DML (which needs to be commited explicitly using TCL) before executing the DDL in the stored proc/function.
You can use any of the following dynamic sql approach to execute a DDL statement from a pl/sql block.
1) Execute immediate
2) DBMS_SQL package
3) DBMS_UTILITY.EXEC_DDL_STATEMENT (parse_string IN VARCHAR2);
Hope this answers your question with explanation.
Fetch vs Pull
Git fetch just updates your repo data, but a git pull will basically perform a fetch and then merge the branch pulled
What is the difference between 'git pull' and 'git fetch'?
Merge vs Rebase
from Atlassian SourceTree Blog, Merge or Rebase:
Merging brings two lines of development together while preserving the ancestry of each commit history.
In contrast, rebasing unifies the lines of development by re-writing changes from the source branch so that they appear as children of the destination branch – effectively pretending that those commits were written on top of the destination branch all along.
Also, check out Learn Git Branching, which is a nice game that has just been posted to HackerNews (link to post) and teaches a lot of branching and merging tricks. I believe it will be very helpful in this matter.
This is a biased answer, but I wrote a library that may simplify the usage of Android Services, if they run locally in the same process as the app: https://github.com/germnix/acacia
Basically you define an interface annotated with @Service and its implementing class, and the library creates and binds the service, handles the connection and the background worker thread:
@Service(ServiceImpl.class)
public interface MyService {
void doProcessing(Foo aComplexParam);
}
public class ServiceImpl implements MyService {
// your implementation
}
MyService service = Acacia.createService(context, MyService.class);
service.doProcessing(foo);
<application
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme">
...
<service android:name="com.gmr.acacia.AcaciaService"/>
...
</application>
You can get an instance of the associated android.app.Service to hide/show persistent notifications, use your own android.app.Service and manually handle threading if you wish.

For a new path to be added to PATH environment variable in MacOS just create a new file under /etc/paths.d
directory and add write path to be set in the file. Restart the terminal. You can check with echo $PATH
at the prompt to confirm if the path was added to the environment variable.
For example: to add a new path /usr/local/sbin
to the PATH
variable:
cd /etc/paths.d
sudo vi newfile
Add the path to the newfile
and save it.
Restart the terminal and type echo $PATH
to confirm
I have to offer this as a better approach - you don't always have the luxury of an identity field:
UPDATE m
SET [status]=10
FROM (
Select TOP (10) *
FROM messages
WHERE [status]=0
ORDER BY [priority] DESC
) m
You can also make the sub-query as complicated as you want - joining multiple tables, etc...
Why is this better? It does not rely on the presence of an identity field (or any other unique column) in the messages
table. It can be used to update the top N rows from any table, even if that table has no unique key at all.
For make a list, simply do that
colors=(red orange white "light gray")

Now it is possible
But you will need to have your device rom run on java 1.8 and enable "jackOptions" to run it. Jack is the name for the new Android compiler that runs Java 8
https://developer.android.com/guide/platform/j8-jack.html
add these lines to build_gradle
android {
...
defaultConfig {
...
jackOptions {
enabled true
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
Java 8 seem to be the running java engine of Android studio 2.0, But it still does not accept the syntax of java 8 after I checked, and you cannot chose a compiler from android studio now. However, you can use the scala plugin if you need functional programming mechanism in your android client.
You can use JQuery .load() method:
$( "#content" ).load( "ajax/test.html div#content" );

{
var configBuilder = new ConfigurationBuilder();
var path = Path.Combine(Directory.GetCurrentDirectory(), "appsettings.json");
configBuilder.AddJsonFile(path, false);
var root = configBuilder.Build();
var appSetting = root.GetSection("ConnectionStrings:DefaultConnection");
sqlConnectionString = appSetting.Value;
}
public string sqlConnectionString { get; set; }
}
DbContext class:
public class DatabaseContext : DbContext
{
public class OptionsBuild
{
public OptionsBuild()
{
setting = new AppConfiguration();
opsBuilder = new DbContextOptionsBuilder<DatabaseContext>();
opsBuilder.UseSqlServer(setting.sqlConnectionString);
dbOptions = opsBuilder.Options;
}
public DbContextOptionsBuilder<DatabaseContext> opsBuilder { get; set; }
public DbContextOptions<DatabaseContext> dbOptions { get; set; }
private AppConfiguration setting { get; set; }
}
public static OptionsBuild ops = new OptionsBuild();
public DatabaseContext(DbContextOptions<DatabaseContext> options) : base(options)
{
//disable initializer
// Database.SetInitializer<DatabaseContext>(null);
}
public DbSet<Account> Account { get; set; }
}
This code should be in your data access layer:
List<Account> accounts = new List<Account>();
var context = new DatabaseContext(DatabaseContext.ops.dbOptions);
accounts = await context.Account.ToListAsync(); //direct select from a table
var param = new SqlParameter("@FirstName", "Bill");
accounts = await context.Account.FromSqlRaw<Account>("exec Proc_Account_Select",
param).ToListAsync(); //procedure call with parameter
accounts = context.Account.FromSqlRaw("SELECT * FROM dbo.Account").ToList(); //raw query

Type 1 : not implemented. collision are possible if the uuid is generated at the same moment. impl can be artificially a-synchronize in order to bypass this problem.
Type 2 : never see a implementation.
Type 3 : md5 hash : collision possible (128 bits-2 technical bytes)
Type 4 : random : collision possible (as lottery). note that the jdk6 impl dont use a "true" secure random because the PRNG algorithm is not choose by developer and you can force system to use a "poor" PRNG algo. So your UUID is predictable.
Type 5 : sha1 hash : not implemented : collision possible (160 bit-2 technical bytes)

var duplicates = lst.GroupBy(s => s)
.SelectMany(grp => grp.Skip(1));
Note that this will return all duplicates, so if you only want to know which items are duplicated in the source list, you could apply Distinct
to the resulting sequence or use the solution given by Mark Byers.
Try perl -MCPAN -e "upgrade /(.\*)/"
. It works fine for me.
For inserting at a particular position k
, you need to traverse the list till the position k-1
and then do the insert.
[You need not create a new node to traverse to that position as you did in your code] You should traverse from the head node.
Try this:
Dim dataView As New DataView(table)
dataView.Sort = " AutoID DESC, Name DESC"
Dim dataTable AS DataTable = dataView.ToTable()
To Find the problem label(s) in a large storyboard, follow my steps below.
Next, reveal your storyboard as source file.
Search. You should be able to tell what label it is from here quite easily by looking at the content.
Once you find the label the solution that worked for me was to set the "preferred width" to 0.
BTW, you can always quickly get the id of an interface item by selecting the item and looking under the identify inspector. Very handy.
You should add parse_dates=True
, or parse_dates=['column name']
when reading, thats usually enough to magically parse it. But there are always weird formats which need to be defined manually. In such a case you can also add a date parser function, which is the most flexible way possible.
Suppose you have a column 'datetime' with your string, then:
from datetime import datetime
dateparse = lambda x: datetime.strptime(x, '%Y-%m-%d %H:%M:%S')
df = pd.read_csv(infile, parse_dates=['datetime'], date_parser=dateparse)
This way you can even combine multiple columns into a single datetime column, this merges a 'date' and a 'time' column into a single 'datetime' column:
dateparse = lambda x: datetime.strptime(x, '%Y-%m-%d %H:%M:%S')
df = pd.read_csv(infile, parse_dates={'datetime': ['date', 'time']}, date_parser=dateparse)
You can find directives (i.e. the letters to be used for different formats) for strptime
and strftime
in this page.
In your head element add
<script type="text/javascript" src="myscript.js"></script>

Off the top of other people's heads:
width
that is not auto
2Note that all of these conditions must be true of the element being centered for it to work.
1 There is one exception to this: if your fixed or absolutely positioned element has left: 0; right: 0
, it will center with auto margins.
2 Technically, margin: 0 auto
does work with an auto width, but the auto width takes precedence over the auto margins, and the auto margins are zeroed out as a result, making it seem as though they "don't work".
mode: 'no-cors'
won’t magically make things work. In fact it makes things worse, because one effect it has is to tell browsers, “Block my frontend JavaScript code from looking at contents of the response body and headers under all circumstances.” Of course you almost never want that.
What happens with cross-origin requests from frontend JavaScript is that browsers by default block frontend code from accessing resources cross-origin. If Access-Control-Allow-Origin
is in a response, then browsers will relax that blocking and allow your code to access the response.
But if a site sends no Access-Control-Allow-Origin
in its responses, your frontend code can’t directly access responses from that site. In particular, you can’t fix it by specifying mode: 'no-cors'
(in fact that’ll ensure your frontend code can’t access the response contents).
However, one thing that will work: if you send your request through a CORS proxy.
You can also easily deploy your own proxy to Heroku in literally just 2-3 minutes, with 5 commands:
git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master
After running those commands, you’ll end up with your own CORS Anywhere server running at, for example, https://cryptic-headland-94862.herokuapp.com/
.
Prefix your request URL with your proxy URL; for example:
https://cryptic-headland-94862.herokuapp.com/https://example.com
Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:
https://example.com
.https://example.com
.Access-Control-Allow-Origin
header to the response.The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin
response header is what the browser sees.
This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS
request, because in that case, the proxy also sends back the Access-Control-Allow-Headers
and Access-Control-Allow-Methods
headers needed to make the preflight successful.
I can hit this endpoint,
http://catfacts-api.appspot.com/api/facts?number=99
via Postman
https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS explains why it is that even though you can access the response with Postman, browsers won’t let you access the response cross-origin from frontend JavaScript code running in a web app unless the response includes an Access-Control-Allow-Origin
response header.
http://catfacts-api.appspot.com/api/facts?number=99 has no Access-Control-Allow-Origin
response header, so there’s no way your frontend code can access the response cross-origin.
Your browser can get the response fine and you can see it in Postman and even in browser devtools—but that doesn’t mean browsers will expose it to your code. They won’t, because it has no Access-Control-Allow-Origin
response header. So you must instead use a proxy to get it.
The proxy makes the request to that site, gets the response, adds the Access-Control-Allow-Origin
response header and any other CORS headers needed, then passes that back to your requesting code. And that response with the Access-Control-Allow-Origin
header added is what the browser sees, so the browser lets your frontend code actually access the response.
So I am trying to pass in an object, to my Fetch which will disable CORS
You don’t want to do that. To be clear, when you say you want to “disable CORS” it seems you actually mean you want to disable the same-origin policy. CORS itself is actually a way to do that — CORS is a way to loosen the same-origin policy, not a way to restrict it.
But anyway, it’s true you can — in just your local environment — do things like give your browser runtime flags to disable security and run insecurely, or you can install a browser extension locally to get around the same-origin policy, but all that does is change the situation just for you locally.
No matter what you change locally, anybody else trying to use your app is still going to run into the same-origin policy, and there’s no way you can disable that for other users of your app.
You most likely never want to use mode: 'no-cors'
in practice except in a few limited cases, and even then only if you know exactly what you’re doing and what the effects are. That’s because what setting mode: 'no-cors'
actually says to the browser is, “Block my frontend JavaScript code from looking into the contents of the response body and headers under all circumstances.” In most cases that’s obviously really not what you want.
As far as the cases when you would want to consider using mode: 'no-cors'
, see the answer at What limitations apply to opaque responses? for the details. The gist of it is that the cases are:
In the limited case when you’re using JavaScript to put content from another origin into a <script>
, <link rel=stylesheet>
, <img>
, <video>
, <audio>
, <object>
, <embed>
, or <iframe>
element (which works because embedding of resources cross-origin is allowed for those) — but for some reason you don’t want to or can’t do that just by having the markup of the document use the resource URL as the href
or src
attribute for the element.
When the only thing you want to do with a resource is to cache it. As alluded to in the answer What limitations apply to opaque responses?, in practice the scenario that applies to is when you’re using Service Workers, in which case the API that’s relevant is the Cache Storage API.
But even in those limited cases, there are some important gotchas to be aware of; see the answer at What limitations apply to opaque responses? for the details.
I have also tried to pass in the object
{ mode: 'opaque'}
There is no mode: 'opaque'
request mode — opaque
is instead just a property of the response, and browsers set that opaque property on responses from requests sent with the no-cors
mode.
But incidentally the word opaque is a pretty explicit signal about the nature of the response you end up with: “opaque” means you can’t see it.
This can be done in a much simpler manner now.
$tmpName = $_FILES['csv']['tmp_name'];
$csvAsArray = array_map('str_getcsv', file($tmpName));
This will return you a parsed array of your CSV data. Then you can just loop through it using a foreach statement.
Using ClipRRect
you need to hardcode BorderRadius
, so if you need complete circular stuff, use ClipOval
instead.
ClipOval(

fit: BoxFit.cover,
),

Dan Abramov's answer is right about redux-thunk
but I will talk a bit more about redux-saga that is quite similar but more powerful.
redux-thunk
is imperative / redux-saga
is declarativeWhen you have a thunk in your hands, like an IO monad or a promise, you can't easily know what it will do once you execute. The only way to test a thunk is to execute it, and mock the dispatcher (or the whole outside world if it interacts with more stuff...).
If you are using mocks, then you are not doing functional programming.
Seen through the lens of side-effects, mocks are a flag that your code is impure, and in the functional programmer's eye, proof that something is wrong. Instead of downloading a library to help us check the iceberg is intact, we should be sailing around it. A hardcore TDD/Java guy once asked me how you do mocking in Clojure. The answer is, we usually don't. We usually see it as a sign we need to refactor our code.
The sagas (as they got implemented in redux-saga
) are declarative and like the Free monad or React components, they are much easier to test without any mock.
See also this article:
in modern FP, we shouldn’t write programs — we should write descriptions of programs, which we can then introspect, transform, and interpret at will.
(Actually, Redux-saga is like a hybrid: the flow is imperative but the effects are declarative)
There is a lot of confusion in the frontend world on how some backend concepts like CQRS / EventSourcing and Flux / Redux may be related, mostly because in Flux we use the term "action" which can sometimes represent both imperative code (LOAD_USER
) and events (USER_LOADED
). I believe that like event-sourcing, you should only dispatch events.
Imagine an app with a link to a user profile. The idiomatic way to handle this with each middleware would be:
redux-thunk
<div onClick={e => dispatch(actions.loadUserProfile(123)}>Robert</div>
function loadUserProfile(userId) {
return dispatch => fetch(`http://data.com/${userId}`)
.then(res => res.json())
.then(
data => dispatch({ type: 'USER_PROFILE_LOADED', data }),
err => dispatch({ type: 'USER_PROFILE_LOAD_FAILED', err })
);
}
redux-saga
<div onClick={e => dispatch({ type: 'USER_NAME_CLICKED', payload: 123 })}>Robert</div>
function* loadUserProfileOnNameClick() {
yield* takeLatest("USER_NAME_CLICKED", fetchUser);
}
function* fetchUser(action) {
try {
const userProfile = yield fetch(`http://data.com/${action.payload.userId }`)
yield put({ type: 'USER_PROFILE_LOADED', userProfile })
}
catch(err) {
yield put({ type: 'USER_PROFILE_LOAD_FAILED', err })
}
}
This saga translates to:
every time a username gets clicked, fetch the user profile and then dispatch an event with the loaded profile.
As you can see, there are some advantages of redux-saga
.
The usage of takeLatest
permits to express that you are only interested to get the data of the last username clicked (handle concurrency problems in case the user click very fast on a lot of usernames). This kind of stuff is hard with thunks. You could have used takeEvery
if you don't want this behavior.
You keep action creators pure. Note it's still useful to keep actionCreators (in sagas put
and components dispatch
), as it might help you to add action validation (assertions/flow/typescript) in the future.
Your code becomes much more testable as the effects are declarative
You don't need anymore to trigger rpc-like calls like actions.loadUser()
. Your UI just needs to dispatch what HAS HAPPENED. We only fire events (always in the past tense!) and not actions anymore. This means that you can create decoupled "ducks" or Bounded Contexts and that the saga can act as the coupling point between these modular components.
This means that your views are more easy to manage because they don't need anymore to contain that translation layer between what has happened and what should happen as an effect
For example imagine an infinite scroll view. CONTAINER_SCROLLED
can lead to NEXT_PAGE_LOADED
, but is it really the responsibility of the scrollable container to decide whether or not we should load another page? Then he has to be aware of more complicated stuff like whether or not the last page was loaded successfully or if there is already a page that tries to load, or if there is no more items left to load? I don't think so: for maximum reusability the scrollable container should just describe that it has been scrolled. The loading of a page is a "business effect" of that scroll
Some might argue that generators can inherently hide state outside of redux store with local variables, but if you start to orchestrate complex things inside thunks by starting timers etc you would have the same problem anyway. And there's a select
effect that now permits to get some state from your Redux store.
Sagas can be time-traveled and also enables complex flow logging and dev-tools that are currently being worked on. Here is some simple async flow logging that is already implemented:
Sagas are not only replacing redux thunks. They come from backend / distributed systems / event-sourcing.
It is a very common misconception that sagas are just here to replace your redux thunks with better testability. Actually this is just an implementation detail of redux-saga. Using declarative effects is better than thunks for testability, but the saga pattern can be implemented on top of imperative or declarative code.
In the first place, the saga is a piece of software that permits to coordinate long running transactions (eventual consistency), and transactions across different bounded contexts (domain driven design jargon).
To simplify this for frontend world, imagine there is widget1 and widget2. When some button on widget1 is clicked, then it should have an effect on widget2. Instead of coupling the 2 widgets together (ie widget1 dispatch an action that targets widget2), widget1 only dispatch that its button was clicked. Then the saga listen for this button click and then update widget2 by dispaching a new event that widget2 is aware of.
This adds a level of indirection that is unnecessary for simple apps, but make it more easy to scale complex applications. You can now publish widget1 and widget2 to different npm repositories so that they never have to know about each others, without having them to share a global registry of actions. The 2 widgets are now bounded contexts that can live separately. They do not need each others to be consistent and can be reused in other apps as well. The saga is the coupling point between the two widgets that coordinate them in a meaningful way for your business.
Some nice articles on how to structure your Redux app, on which you can use Redux-saga for decoupling reasons:
I want my components to be able to trigger the display of in-app notifications. But I don't want my components to be highly coupled to the notification system that has its own business rules (max 3 notifications displayed at the same time, notification queueing, 4 seconds display-time etc...).
I don't want my JSX components to decide when a notification will show/hide. I just give it the ability to request a notification, and leave the complex rules inside the saga. This kind of stuff is quite hard to implement with thunks or promises.
I've described here how this can be done with saga
The term saga comes from the backend world. I initially introduced Yassine (the author of Redux-saga) to that term in a long discussion.
Initially, that term was introduced with a paper, the saga pattern was supposed to be used to handle eventual consistency in distributed transactions, but its usage has been extended to a broader definition by backend developers so that it now also covers the "process manager" pattern (somehow the original saga pattern is a specialized form of process manager).
Today, the term "saga" is confusing as it can describe 2 different things. As it is used in redux-saga, it does not describe a way to handle distributed transactions but rather a way to coordinate actions in your app. redux-saga
could also have been called redux-process-manager
.
See also:
If you don't like the idea of using generators but you are interested by the saga pattern and its decoupling properties, you can also achieve the same with redux-observable which uses the name epic
to describe the exact same pattern, but with RxJS. If you're already familiar with Rx, you'll feel right at home.
const loadUserProfileOnNameClickEpic = action$ =>
action$.ofType('USER_NAME_CLICKED')
.switchMap(action =>
Observable.ajax(`http://data.com/${action.payload.userId}`)
.map(userProfile => ({
type: 'USER_PROFILE_LOADED',
userProfile
}))
.catch(err => Observable.of({
type: 'USER_PROFILE_LOAD_FAILED',
err
}))
);
yield put(someActionThunk)
if it makes sense.If you are frightened of using Redux-saga (or Redux-observable) but just need the decoupling pattern, check redux-dispatch-subscribe: it permits to listen to dispatches and trigger new dispatches in listener.
const unsubscribe = store.addDispatchListener(action => {
if (action.type === 'ping') {
store.dispatch({ type: 'pong' });
}
});
Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.
Knowing this thread is marked as solved, it shows up early on Google Search for the given term. So I thought it might be useful to mention another reason that can lead to this error.

Why use int
at all?
Apple uses int
because for a loop control variable (which is only used to control the loop iterations) int
datatype is fine, both in datatype size and in the values it can hold for your loop. No need for platform dependent datatype here. For a loop control variable even a 16-bit int
will do most of the time.
Apple uses NSInteger
for a function return value or for a function argument because in this case datatype [size] matters, because what you are doing with a function is communicating/passing data with other programs or with other pieces of code; see the answer to When should I be using NSInteger vs int? in your question itself...
they [Apple] use NSInteger (or NSUInteger) when passing a value as an argument to a function or returning a value from a function.
Another option would be to use the chromestorage API. This allows storage of user data with optional syncing across sessions.
One downside is that it is asynchronous.
You can control the <br>
height if you put it inside a height limited div. Try:
<div style="height:2px;"><br></div>
React Native buttons are very limited in the option they provide.You can use TouchableHighlight or TouchableOpacity by styling these element and wrapping your buttons with it like this
<TouchableHighlight
style ={{
height: 40,
width:160,
borderRadius:10,
backgroundColor : "yellow",
marginLeft :50,
marginRight:50,
marginTop :20
}}>
<Button onPress={this._onPressButton}
title="SAVE"
accessibilityLabel="Learn more about this button"
/>
</TouchableHighlight>
You can also use react library for customised button .One nice library is react-native-button (https://www.npmjs.com/package/react-native-button)
The easiest way (requires Glide 4.x.x)
Glide.with(context).load(uri).apply(RequestOptions().circleCrop()).into(imageView)
To get an image from a URL we can use the following code:
ImageIcon imgThisImg = new ImageIcon(PicURL));
jLabel2.setIcon(imgThisImg);
It totally works for me. The PicUrl is a string variable which strores the url of the picture.
You can implement non-blocking locks using compareAndSwap (CAS) on atomic integers or longs. The "Tl2" Software Transactional Memory paper describes this:
We associate a special versioned write-lock with every transacted memory location. In its simplest form, the versioned write-lock is a single word spinlock that uses a CAS operation to acquire the lock and a store to release it. Since one only needs a single bit to indicate that the lock is taken, we use the rest of the lock word to hold a version number.
What it is describing is first read the atomic integer. Split this up into an ignored lock-bit and the version number. Attempt to CAS write it as the lock-bit cleared with the current version number to the lock-bit set and the next version number. Loop until you succeed and your are the thread which owns the lock. Unlock by setting the current version number with the lock-bit cleared. The paper describes using the version numbers in the locks to coordinate that threads have a consistent set of reads when they write.
This article describes that processors have hardware support for compare and swap operations making the very efficient. It also claims:
non-blocking CAS-based counters using atomic variables have better performance than lock-based counters in low to moderate contention
You can also do this to set a header for all future gets for the Session object, where x-test will be in all s.get() calls:
s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})
# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})
from: http://docs.python-requests.org/en/latest/user/advanced/#session-objects
There is not a way to directly get the version out, but there are two work-arounds that could be done.
The version could be stored in a resource string, and placed into the manifest by:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.somepackage"
android:versionName="@string/version" android:versionCode="20">
One could create a custom view, and place it into the XML. The view would use this to assign the name:
context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version
or something like that.
In Rails 3, I don't know anything fancier. However, I'm not sure if you're aware, your not equal condition does not match for (user_id) NULL values. If you want that, you'll have to do something like this:
GroupUser.where("user_id != ? OR user_id IS NULL", me)
Here the simples
a = [x for x in 'abcdefgh'] #['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
It's a weird design, but the TableLayoutPanel.RowCount
property doesn't reflect the count of the RowStyles
collection, and similarly for the ColumnCount
property and the ColumnStyles
collection.
What I've found I needed in my code was to manually update RowCount
/ColumnCount
after making changes to RowStyles
/ColumnStyles
.
Here's an example of code I've used:
/// <summary>
/// Add a new row to our grid.
/// </summary>
/// The row should autosize to match whatever is placed within.
/// <returns>Index of new row.</returns>
public int AddAutoSizeRow()
{
Panel.RowStyles.Add(new RowStyle(SizeType.AutoSize));
Panel.RowCount = Panel.RowStyles.Count;
mCurrentRow = Panel.RowCount - 1;
return mCurrentRow;
}
Other thoughts
I've never used DockStyle.Fill
to make a control fill a cell in the Grid; I've done this by setting the Anchors
property of the control.
If you're adding a lot of controls, make sure you call SuspendLayout
and ResumeLayout
around the process, else things will run slow as the entire form is relaid after each control is added.
Just to add an answer as per my latest experience and working on VueJs. I found below piece of code ad best, which does not impact your application in anyways.
const el = this.$el.getElementsByClassName('your_element_class')[0];
if (el) {
scrollIntoView(el,
{
block: 'nearest',
inline: 'start',
behavior: 'smooth',
boundary: document.getElementsByClassName('main_app_class')[0]
});
}
main_app_class
is the root class
your_element_class
is the element/view where you can to scroll into
And for browser which does not support ScrollIntoView() just use below library its awesome https://www.npmjs.com/package/scroll-into-view-if-needed
Above answers are in python2. So for python 3 users I am giving this answer. You can use the bellow code:
import pandas as pd
fields = ['star_name', 'ra']
df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print(df.keys())
# See content in 'star_name'
print(df.star_name)
If you are not wanting to use async
you can add .Result
to force the code to execute synchronously:
private string GetResponseString(string text)
{
var httpClient = new HttpClient();
var parameters = new Dictionary<string, string>();
parameters["text"] = text;
var response = httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters)).Result;
var contents = response.Content.ReadAsStringAsync().Result;
return contents;
}
It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.
Solve all your compilation errors first.
Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.
You can check the long-running queries details like % completed and remaining time using the below query:
SELECT SID, SERIAL#, OPNAME, CONTEXT, SOFAR,
TOTALWORK,ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETE"
FROM V$SESSION_LONGOPS
WHERE OPNAME NOT LIKE '%aggregate%'
AND TOTALWORK != 0
AND SOFAR <> TOTALWORK;
For the complete list of troubleshooting steps, you can check here:Troubleshooting long running sessions
You didn't declare it before you used it.
You need something like
char *do_something(char *, const char *);
before the printf.
Example:
#include <stdio.h>
char *do_something(char *, const char *);
char dest[5];
char src[5] = "test";
int main ()
{
printf("String: %s\n", do_something(dest, src));
return 0;
}
char *do_something(char *dest, const char *src)
{
return dest;
}
Alternatively, you can put the whole do_something
function before the printf.
Use Like below format code
$('#title').keypress(function(event){
//get envent value
var inputValue = event.which;
// check whitespaces only.
if(inputValue == 32){
return true;
}
// check number only.
if(inputValue == 48 || inputValue == 49 || inputValue == 50 || inputValue == 51 || inputValue == 52 || inputValue == 53 || inputValue == 54 || inputValue == 55 || inputValue == 56 || inputValue == 57){
return true;
}
// check special char.
if(!(inputValue >= 65 && inputValue <= 120) && (inputValue != 32 && inputValue != 0)) {
event.preventDefault();
}
})
Often i reach for the abbreviation html tag in this situation.
<abbr title="Hover">Text</abbr>
Some of the system headers provide a forward declaration of std::stringstream
without the definition. This makes it an 'incomplete type'. To fix that you need to include the definition, which is provided in the <sstream>
header:
#include <sstream>
This will get you to an answer for your simple case, but can you expand on how you'll know which columns will need to be compared (B and C in this case) and what the initial range (A1:D5
in this case) will be? Then I can try to provide a more complete answer.
Sub setCondFormat()
Range("B3").Select
With Range("B3:H63")
.FormatConditions.Add Type:=xlExpression, Formula1:= _
"=IF($D3="""",FALSE,IF($F3>=$E3,TRUE,FALSE))"
With .FormatConditions(.FormatConditions.Count)
.SetFirstPriority
With .Interior
.PatternColorIndex = xlAutomatic
.Color = 5287936
.TintAndShade = 0
End With
End With
End With
End Sub
Note: this is tested in Excel 2010.
Edit: Updated code based on comments.
First, I'd make sure that this really is a performance bottleneck, otherwise I'd go with the solution that is cleanest and most expressive.
If it IS a performance bottleneck, just try the different strategies and see what's the quickest. My bet is on creating a new ArrayList and puting the desired objects in that one, discarding the old ArrayList.
Below script works perfectly:
sqlcmd -s Server_name -d Database_name -E -i c:\Temp\Recovery_script.sql -x
Symptoms:
When executing a recovery script with sqlcmd utility, the ‘Sqlcmd: Error: Syntax error at line XYZ near command ‘X’ in file ‘file_name.sql’.’ error is encountered.
Cause:
This is a sqlcmd utility limitation. If the SQL script contains dollar sign ($) in any form, the utility is unable to properly execute the script, since it is substituting all variables automatically by default.
Resolution:
In order to execute script that has a dollar ($) sign in any form, it is necessary to add “-x” parameter to the command line.
e.g.
Original: sqlcmd -s Server_name -d Database_name -E -i c:\Temp\Recovery_script.sql
Fixed: sqlcmd -s Server_name -d Database_name -E -i c:\Temp\Recovery_script.sql -x
The Java Native Access library is typically used for calling native shared libraries from Java. Within this library there exist methods for determining the size of Java objects:
The getNativeSize(Class cls)
method and its overloads will provide the size for most classes.
Alternatively, if your classes inherit from JNA's Structure class the calculateSize(boolean force)
method will be available.
I do not know why you are defining the parameter outside the script. That is unnecessary. Your callback function will be called with the return data as a parameter automatically. It is very possible to define your callback outside the sucess:
i.e.
function getData() {
$.ajax({
url : 'example.com',
type: 'GET',
success : handleData
})
}
function handleData(data) {
alert(data);
//do some stuff
}
the handleData function will be called and the parameter passed to it by the ajax function.
That error message usually means that either the password we are using doesn't match what MySQL thinks the password should be for the user we're connecting as, or a matching MySQL user doesn't exist (hasn't been created).
In MySQL, a user is identified by both a username ("test2") and a host ("localhost").
The error message identifies the user ("test2") and the host ("localhost") values...
'test2'@'localhost'
We can check to see if the user exists, using this query from a client we can connect from:
SELECT user, host FROM mysql.user
We're looking for a row that has "test2" for user, and "localhost" for host.
user host
------- -----------
test2 127.0.0.1 cleanup
test2 ::1
test2 localhost
If that row doesn't exist, then the host may be set to wildcard value of %
, to match any other host that isn't a match.
If the row exists, then the password may not match. We can change the password (if we're connected as a user with sufficient privileges, e.g. root
SET PASSWORD FOR 'test2'@'localhost' = PASSWORD('mysecretcleartextpassword')
We can also verify that the user has privileges on objects in the database.
GRANT SELECT ON jobs.* TO 'test2'@'localhost'
EDIT
If we make changes to mysql privilege tables with DML operations (INSERT,UPDATE,DELETE), those changes will not take effect until MySQL re-reads the tables. We can make changes effective by forcing a re-read with a FLUSH PRIVILEGES
statement, executed by a privileged user.
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.
Interfaces specify behavior of an object.
Static methods do not specify a behavior of an object, but behavior that affects an object in some way.
Try -
Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2)
As for the reason, this from MSDN via this question - What does the Call keyword do in VB6?
You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.
You should definitely give a more detailed explanation in the response headers and/or body (e.g. with a custom header - X-Status-Reason: Validation failed
).
If an Immutable/Singleton collections refers to the one which having only one object and which is not further gets modified, then the same functionality can be achieved by making a collection "UnmodifiableCollection" having only one object. Since the same functionality can be achieved by Unmodifiable Collection with one object, then what special purpose the Singleton Collection serves for?
To install Redis on Windows system follow the below steps:
https://github.com/MSOpenTech/redis/releases (recommended) https://github.com/rgl/redis/downloads
Now open your Terminal (command prompt) and run redis-cli
Well I am getting some error to open redis-server
(It was working fine till now but not sure what's wrong so figuring out and will update this answer)
This is how I do it:
with open(txtfile, 'r') as infile, open(csvfile, 'w') as outfile:
stripped = (line.strip() for line in infile)
lines = (line.split(",") for line in stripped if line)
writer = csv.writer(outfile)
writer.writerows(lines)
Hope it helps!

CSS Styles are key-value pairs, not just "tags". By default, each element has a full set of CSS styles assigned to it, most of them is implicitly using the browser defaults and some of them is explicitly redefined in CSS stylesheets.
To get the value assigned to a particular CSS entry of an element and compare it:
if ($('#yourElement').css('position') == 'absolute')
{
// true
}
If you didn't redefine the style, you will get the browser default for that particular element.
The second one is a classic example of the Arrow Anti-pattern So I'd avoid it...
If your conditions are too long extract them into methods/properties.
T-SQL
declare @thirtydaysago datetime
declare @now datetime
set @now = getdate()
set @thirtydaysago = dateadd(day,-30,@now)

Add a method to your page class like this:
public string YesNo(bool active)
{
return active ? "Yes" : "No";
}
And then in your TemplateField
you Bind
using this method:
<%# YesNo(Active) %>
May use this-
#if defined CONDITION1 || defined CONDITION2
//your code here
#endif
This also does the same-
#if defined(CONDITION1) || defined(CONDITION2)
//your code here
#endif
Further-
#if defined CONDITION1 && defined CONDITION2
#if defined CONDITION1 ^ defined CONDITION2
#if defined CONDITION1 && !defined CONDITION2
Let's me give a more detail example. As to the below struct:
struct Count{
uint32_t c;
Count(uint32_t i=0):c(i){}
uint32_t getCount(){
return c;
}
uint32_t add(const Count& count){
uint32_t total = c + count.getCount();
return total;
}
};
As you see the above, the IDE(CLion), will give tips Non-const function 'getCount' is called on the const object
. In the method add
count
is declared as const object, but the method getCount
is not const method, so count.getCount()
may change the members in count
.
Compile error as below(core message in my compiler):
error: passing 'const xy_stl::Count' as 'this' argument discards qualifiers [-fpermissive]
To solve the above problem, you can:
uint32_t getCount(){...}
to uint32_t getCount() const {...}
. So count.getCount()
won't change the members in count
.or
uint32_t add(const Count& count){...}
to uint32_t add(Count& count){...}
. So count
don't care about changing members in it.As to you problem, objects in the std::set are stored as const StudentT, but the method getId
and getName
are not const, so you give the above error.
You can also see this question Meaning of 'const' last in a function declaration of a class? for more detail.
1 to 10:
[0-9]{1,10}
In .NET (and not only, see the comment below) also valid (with a stipulation) this:
\d{1,10}
C#:
var regex = new Regex("^[0-9]{1,10}$", RegexOptions.Compiled);
regex.IsMatch("1"); // true
regex.IsMatch("12"); // true
..
regex.IsMatch("1234567890"); // true
regex.IsMatch(""); // false
regex.IsMatch(" "); // true
regex.IsMatch("a"); // false
P.S. Here's a very useful sandbox.
Provide appropriate permissions with this command
sudo chmod 777 -R /dev/kvm
A REGEXP_LIKE
will do a case-insensitive regexp search.
select * from Users where Regexp_Like (User_Name, 'karl|anders|leif','i')
This will be executed as a full table scan - just as the LIKE or
solution, so the performance will be really bad if the table is not small. If it's not used often at all, it might be ok.
If you need some kind of performance, you will need Oracle Text (or some external indexer).
To get substring indexing with Oracle Text you will need a CONTEXT index. It's a bit involved as it's made for indexing large documents and text using a lot of smarts. If you have particular needs, such as substring searches in numbers and all words (including "the" "an" "a", spaces, etc) , you need to create custom lexers to remove some of the smart stuff...
If you insert a lot of data, Oracle Text will not make things faster, especially if you need the index to be updated within the transactions and not periodically.
Update! New & improved! Find plugin @ GitHub!
On another note, while that method is simple, I've created a jQuery plug (found at this jsFiddle, just copy and past code between comment lines) that makes changing the cursor on any element as simple as $("element").cursor("pointer")
.
But that's not all! Act now and you'll get the hand functions position
& ishover
for no extra charge! That's right, 2 very handy cursor functions ... FREE!
They work as simple as seen in the demo:
$("h3").cursor("isHover"); // if hovering over an h3 element, will return true,
// else false
// also handy as
$("h2, h3").cursor("isHover"); // unless your h3 is inside an h2, this will be
// false as it checks to see if cursor is hovered over both elements, not just the last!
// And to make this deal even sweeter - use the following to get a jQuery object
// of ALL elements the cursor is currently hovered over on demand!
$.cursor("isHover");
Also:
$.cursor("position"); // will return the current cursor position as { x: i, y: i }
// at anytime you call it!
Supplies are limited, so Act Now!
you can write a generic method as (its too late but below code will help you/others)
public static FileInputStream getFile(File fileImport) throws IOException {
FileInputStream fileStream = null;
try {
PrintWriter writer = new PrintWriter(fileImport);
writer.print(StringUtils.EMPTY);
fileStream = new FileInputStream(fileImport);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
writer.close();
}
return fileStream;
}
Let me put state my case since it was different from all the above solutions. I had an html tag that wasn't closed correctly. the element was not required
, but it was embedded in a hidden
div
the problem in my case was with the type="datetime-local"
, which was -for some reason- being validated at form submission.
i changed this
<input type="datetime-local" />
into that
<input type="text" />
check this fiddle , and if you want to move the overlapped div you set its position to absolute
then change it's top
and left
values
Use UITextView
instead of UILabel
and it has a property to convert your text to hyperlink.
yourTextView.editable = NO;
yourTextView.dataDetectorTypes = UIDataDetectorTypeAll;
yourTextView.editable = false;
yourTextView.dataDetectorTypes = UIDataDetectorTypes.All;
This will detect links automatically.
See the documentation for details.
In our Business Objects we have 2 main Get methods:
To keep things simple in the context or you question they would be:
// Returns null if user does not exist
public UserEntity GetUserById(Guid userId)
{
}
// Returns a New User if user does not exist
public UserEntity GetNewOrExistingUserById(Guid userId)
{
}
The first method is used when getting specific entities, the second method is used specifically when adding or editing entities on web pages.
This enables us to have the best of both worlds in the context where they are used.
Tim Storer wrote a more flexible and nicer looking timeline.sty
(Internet Archive Wayback Machine link, as original is gone). In addition, the line is horizontal rather than vertical. So for instance:
\begin{timeline}{2008}{2010}{50}{250}
\MonthAndYearEvent{4}{2008}{First Podcast}
\MonthAndYearEvent{7}{2008}{Private Beta}
\MonthAndYearEvent{9}{2008}{Public Beta}
\YearEvent{2009}{IPO?}
\end{timeline}
produces a timeline that looks like this:
2008 2010
· · April, 2008 First Podcast ·
· July, 2008 Private Beta
· September, 2008 Public Beta
· 2009 IPO?
Personally, I find this a more pleasing solution than the other answers. But I also find myself modifying the code to get something closer to what I think a timeline should look like. So there's not definitive solution in my opinion.
It's the same origin policy, you have to use a JSON-P interface or a proxy running on the same host.
The bookmarks extension mentioned in the accepted answer conflicts with toggling breakpoints via the margin.
You could do the same with breakpoints and select the debug tab on the left to see them listed. Better yet, use File, Preferences, Keyboard Shortcuts and set (Shift+)Ctrl+F9 to navigate between them, even across files:
If your XML goes quite deep, you might want to consider using XPath, which comes with your JRE, so you can access the contents far more easily using:
String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
document.getDocumentElement());
Full example:
import static org.junit.Assert.assertEquals;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;
import org.junit.Before;
import org.junit.Test;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;
public class XPathTest {
private Document document;
@Before
public void setup() throws Exception {
String xml = "<add job=\"351\"><tag>foobar</tag><tag>foobar2</tag></add>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
document = db.parse(new InputSource(new StringReader(xml)));
}
@Test
public void testXPath() throws Exception {
XPathFactory xpf = XPathFactory.newInstance();
XPath xp = xpf.newXPath();
String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
document.getDocumentElement());
assertEquals("foobar", text);
}

It's better to use the string in the strings file, as such:
<string name="some_text">
<![CDATA[

</string>
Usage:
textView.text=HtmlCompat.fromHtml(getString(R.string.some_text), HtmlCompat.FROM_HTML_MODE_LEGACY)
If you want to hide overflow on fixed-position elements, the simplest approach I've found is to place the element inside a container element, and apply position:fixed
and overflow:hidden
to that element instead of the contained element (you must remove position:fixed
from the contained element for this to work). The content of the fixed container should then be clipped as expected.
In my case I was having trouble with using object-fit:cover
on a fixed-position element (it was spilling outside the bounds of the page body, regardless of overflow:hidden
). Placing it inside a fixed container with overflow:hidden
on the container fixed the issue.

Hopefully this is helpful to others.
In Word, it is possible to paste code that uses color to differentiate comments from code using "Paste Keep Source Formatting." However, if you use the pasted code to create a new style, Word automatically strips the color coded text and changes them to be black (or whatever the auto default color is). Since applying a style is the best way to ensure compliance with document format requirements, Word is not very useful for documenting software programs. Unfortunately, I don't recall Open Office being any better. The best work-around is to use the default simple text box.
SELECT distinct
group,
max_date = MAX(date) OVER (PARTITION BY group), checks

Should work.
You can use jQuery's .eq()
method to get the element with a certain index.
$('ul li').eq(index).css({'background-color':'#343434'});
As Hogan notes above, use an AND
instead of &
. See this tutorial for more info.
In code level also, you could add your lib to the project using the compiler directives #pragma.
example:
#pragma comment( lib, "yourLibrary.lib" )
You installed Python and added it to PATH. You've checked it too(like 64-bit etc). Everything should work but it is not.
what you didn't do is a
terminal/cmd restart
restart your terminal and everything would work like a charm.
I Hope, it helped/might help others.
The best way to solve this problem would be by starting with customizing Bootstrap using their customization tools.

Go down to @headings-color and change it from "inherit" to something that you would like your headers to be across the site (if you like the default just change it to #333).
Note that this will keep all your headings the same color, as you requested.
Now in order to accomplish what you want that after you make this change you can now overwrite them specifically in your own CSS to apply your own color to them. The "inherit" keyword I always have found to be a pain in frameworks.
printf("%.<number>f", myFloat) //where <number> - digit after comma
A dialect is a form of the language that is spoken by a particular group of people.
Here, in context of hibernate framework, When hibernate wants to talk(using queries) with the database it uses dialects.
The SQL dialect's are derived from the Structured Query Language which uses human-readable expressions to define query statements.
A hibernate dialect gives information to the framework of how to convert hibernate queries(HQL) into native SQL queries.
The dialect of hibernate can be configured using below property:
hibernate.dialect
Here, is a complete list of hibernate dialects.
Note: The dialect property of hibernate is not mandatory.
You can execute any shell command using the shelljs module

A new library called ts-optchain provides this functionality, and unlike lodash' solution, it also keeps your types safe, here is a sample of how it is used (taken from the readme):
import { oc } from 'ts-optchain';
interface I {
a?: string;
b?: {
d?: string;
};
c?: Array<{
u?: {
v?: number;
};
}>;
e?: {
f?: string;
g?: () => string;
};
}
const x: I = {
a: 'hello',
b: {
d: 'world',
},
c: [{ u: { v: -100 } }, { u: { v: 200 } }, {}, { u: { v: -300 } }],
};
// Here are a few examples of deep object traversal using (a) optional chaining vs
// (b) logic expressions. Each of the following pairs are equivalent in
// result. Note how the benefits of optional chaining accrue with
// the depth and complexity of the traversal.
oc(x).a(); // 'hello'
x.a;
oc(x).b.d(); // 'world'
x.b && x.b.d;
oc(x).c[0].u.v(); // -100
x.c && x.c[0] && x.c[0].u && x.c[0].u.v;
oc(x).c[100].u.v(); // undefined
x.c && x.c[100] && x.c[100].u && x.c[100].u.v;
oc(x).c[100].u.v(1234); // 1234
(x.c && x.c[100] && x.c[100].u && x.c[100].u.v) || 1234;
oc(x).e.f(); // undefined
x.e && x.e.f;
oc(x).e.f('optional default value'); // 'optional default value'
(x.e && x.e.f) || 'optional default value';
// NOTE: working with function value types can be risky. Additional run-time
// checks to verify that object types are functions before invocation are advised!
oc(x).e.g(() => 'Yo Yo')(); // 'Yo Yo'
((x.e && x.e.g) || (() => 'Yo Yo'))();
As Diodeus stated, IE doesn't allow anything but the default border for <select>
elements. However, I know of two hacks to achieve a similar effect :
Use a DIV that is placed absolutely at the same position as the dropdown and set it's borders. It will appear that the dropdown has a border.
Use a Javascript solution, for instance, the one provided here.
It may however prove to be too much effort, so you should evaluate if you really require the border.
declare @p varbinary(max)
set @p = 0x
declare @local table (col text)
SELECT @p = @p + 0x3B + CONVERT(varbinary(100), Email)
FROM tbCarsList
where email <> ''
group by email
order by email
set @p = substring(@p, 2, 100000)
insert @local values(cast(@p as varchar(max)))
select DATALENGTH(col) as collen, col from @local
result collen > 8000, length col value is more than 8000 chars
There is an open-source javascript plugin that does just that, but for any browser - debugout.js
Debugout.js records and save console.logs so your application can access them. Full disclosure, I wrote it. It formats different types appropriately, can handle nested objects and arrays, and can optionally put a timestamp next to each log. You can also toggle live-logging in one place, and without having to remove all your logging statements.

However you should be filtering your query. At the moment your query is all()
Todo's.
todos = Todo.all().filter('author = ', users.get_current_user().nickname())
or
todos = Todo.all().filter('author = ', users.get_current_user())
depending on what you are defining author as in the Todo model. A StringProperty
or UserProperty
.
Note nickname
is a method. You are passing the method and not the result in template values.
Try with this code:
from PIL import Image
Image.fromarray(image).show()
It also can be used for creating scopes for Example:
class LoggerScope:IDisposable {
static ThreadLocal<LoggerScope> threadScope =
new ThreadLocal<LoggerScope>();
private LoggerScope previous;
public static LoggerScope Current=> threadScope.Value;
public bool WithTime{get;}
public LoggerScope(bool withTime){
previous = threadScope.Value;
threadScope.Value = this;
WithTime=withTime;
}
public void Dispose(){
threadScope.Value = previous;
}
}
class Program {
public static void Main(params string[] args){
new Program().Run();
}
public void Run(){
log("something happend!");
using(new LoggerScope(false)){
log("the quick brown fox jumps over the lazy dog!");
using(new LoggerScope(true)){
log("nested scope!");
}
}
}
void log(string message){
if(LoggerScope.Current!=null){
Console.WriteLine(message);
if(LoggerScope.Current.WithTime){
Console.WriteLine(DateTime.Now);
}
}
}
}
you can use PATTERN:
<input class="form-control" minlength="1" pattern="[0-9]*" [(ngModel)]="value" #name="ngModel">
<div *ngIf="name.invalid && (name.dirty || name.touched)" class="text-danger">
<div *ngIf="name.errors?.pattern">Is not a number</div>
</div>
select sum([rows])
from sys.partitions
where object_id=object_id('tablename')
and index_id in (0,1)
is very fast but very rarely inaccurate.
Pseudo code, something like:
CASE
When CHARINDEX('lactulose', dbo.Table.Column) > 0 Then 'BP Medication'
ELSE ''
END AS 'Medication Type'
This does not care where the keyword is found in the list and avoids depending on formatting of spaces and commas.
\df+

Just assigning the value and committing them will work for all the data types but JSON and Pickled attributes. Since pickled type is explained above I'll note down a slightly different but easy way to update JSONs.
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80), unique=True)
data = db.Column(db.JSON)
def __init__(self, name, data):
self.name = name
self.data = data
Let's say the model is like above.
user = User("Jon Dove", {"country":"Sri Lanka"})
db.session.add(user)
db.session.flush()
db.session.commit()
This will add the user into the MySQL database with data {"country":"Sri Lanka"}
Modifying data will be ignored. My code that didn't work is as follows.
user = User.query().filter(User.name=='Jon Dove')
data = user.data
data["province"] = "south"
user.data = data
db.session.merge(user)
db.session.flush()
db.session.commit()
Instead of going through the painful work of copying the JSON to a new dict (not assigning it to a new variable as above), which should have worked I found a simple way to do that. There is a way to flag the system that JSONs have changed.
Following is the working code.
from sqlalchemy.orm.attributes import flag_modified
user = User.query().filter(User.name=='Jon Dove')
data = user.data
data["province"] = "south"
user.data = data
flag_modified(user, "data")
db.session.merge(user)
db.session.flush()
db.session.commit()
This worked like a charm. There is another method proposed along with this method here Hope I've helped some one.
I could be wrong but I thought it used IE's proxy settings.
If it sees that you need to login it opens a dialog and asks you to do so (login that is).

Note that in my Android Studio 1.4, Auto Import now under General
(Android Studio --> Preferences --> Editors --> General --> Auto Import)
public class StringReverse1 {
public static void main(String[] args) {
String name = "Vaquar khan";
char array[] = name.toCharArray();
System.out.println(name);
System.out.println(reverseString(array));
}
private static String reverseString(char[] array) {
String reverse = "";
///
for (int i = array.length - 1; i >= 0; i--) {
//System.out.println(array[i]);
//
reverse += array[i];
}
return reverse;
}
}
Results :

If you have integers in your file fscanf returns 1 until integer occurs. For example:
FILE *in = fopen("./task.in", "r");
int length = 0;
int counter;
int sequence;
for ( int i = 0; i < 10; i++ ) {
counter = fscanf(in, "%d", &sequence);
if ( counter == 1 ) {
length += 1;
}
}
To find out the end of the file with symbols you can use EOF. For example:
char symbol;
FILE *in = fopen("./task.in", "r");
for ( ; fscanf(in, "%c", &symbol) != EOF; ) {
printf("%c", symbol);
}
You could put it as a startup item... Startup items don't show off a prompt to run as an administrator at all.

You haven't specified how would you like to see these details.
For the first sight I would suggest to check Server Management Studio.
You can see the jobs and current statuses in the SQL Server Agent part, under Jobs. If you pick a job, the Property page shows a link to the Job History, where you can see the start and end time, if there any errors, which step caused the error, and so on.
You can specify alerts and notifications to email you or to page you when the job finished successfully or failed.
There is a Job Activity Monitor, but actually I never used it. You can have a try.
If you want to check it via T-SQL, then I don't know how you can do that.
I have used enum FragmentTags
to define all my fragment classes.
TAG_FOR_FRAGMENT_A(A.class),
TAG_FOR_FRAGMENT_B(B.class),
TAG_FOR_FRAGMENT_C(C.class)
pass FragmentTags.TAG_FOR_FRAGMENT_A.name()
as fragment tag.
and now on
@Override
public void onBackPressed(){
FragmentManager fragmentManager = getFragmentManager();
Fragment current
= fragmentManager.findFragmentById(R.id.fragment_container);
FragmentTags fragmentTag = FragmentTags.valueOf(current.getTag());
switch(fragmentTag){
case TAG_FOR_FRAGMENT_A:
finish();
break;
case TAG_FOR_FRAGMENT_B:
fragmentManager.popBackStack();
break;
case default:
break;
}
In SQL Server 2012 it is very very easy
SELECT col1, col2, ...
FROM ...
WHERE ...
ORDER BY -- this is a MUST there must be ORDER BY statement
-- the paging comes here
OFFSET 10 ROWS -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows
If we want to skip ORDER BY we can use
SELECT col1, col2, ...
...
ORDER BY CURRENT_TIMESTAMP
OFFSET 10 ROWS -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows
(I'd rather mark that as a hack - but it's used, e.g. by NHibernate. To use a wisely picked up column as ORDER BY is preferred way)
to answer the question:
--SQL SERVER 2012
SELECT PostId FROM
( SELECT PostId, MAX (Datemade) as LastDate
from dbForumEntry
group by PostId
) SubQueryAlias
order by LastDate desc
OFFSET 10 ROWS -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows
New key words offset
and fetch next
(just following SQL standards) were introduced.
But I guess, that you are not using SQL Server 2012, right? In previous version it is a bit (little bit) difficult. Here is comparison and examples for all SQL server versions: here
So, this could work in SQL Server 2008:
-- SQL SERVER 2008
DECLARE @Start INT
DECLARE @End INT
SELECT @Start = 10,@End = 20;
;WITH PostCTE AS
( SELECT PostId, MAX (Datemade) as LastDate
,ROW_NUMBER() OVER (ORDER BY PostId) AS RowNumber
from dbForumEntry
group by PostId
)
SELECT PostId, LastDate
FROM PostCTE
WHERE RowNumber > @Start AND RowNumber <= @End
ORDER BY PostId
../
takes you one folder up the directory tree. Then, select the appropriate folder and its contents.

If you can use Guava library, since version 21, you can use
Streams.stream(iterable)
In web.config add this under system.webserver tag as below,
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Replace">
<remove statusCode="404"/>
<remove statusCode="500"/>
<error statusCode="404" responseMode="ExecuteURL" path="/Error/NotFound"/>
<error statusCode="500" responseMode="ExecuteURL"path="/Error/ErrorPage"/>
</httpErrors>
and add a controller as,
public class ErrorController : Controller
{
//
// GET: /Error/
[GET("/Error/NotFound")]
public ActionResult NotFound()
{
Response.StatusCode = 404;
return View();
}
[GET("/Error/ErrorPage")]
public ActionResult ErrorPage()
{
Response.StatusCode = 500;
return View();
}
}
and add their respected views, this will work definitely I guess for all.
