Just change the directory to another one and come back. Probably that one has been deleted or moved.
If you just want to execute the shell command in your c program, you could use,
#include <stdlib.h>
int system(const char *command);
In your case,
system("pwd");
The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.
What do you mean by this? You should be able to find the mentioned packages in /bin/
sudo find / -executable -name pwd
sudo find / -executable -name echo
There are actually a few ways this can be done:
1: Download
You can download the latest version of jQuery and then include it in your page with a standard HTML script tag. This can be done within the master or an individual page.
HTML5
<script src="/scripts/jquery-2.1.0.min.js"></script>
HTML4
<script src="/scripts/jquery-2.1.0.min.js" type="text/javascript"></script>
2: Content Delivery Network
You can include jQuery to your site using a CDN (Content Delivery Network) such as Google's. This should help reduce page load times if the user has already visited a site using the same version from the same CDN.
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
3: NuGet Package Manager
Lastly, (my preferred) use NuGet which is shipped with Visual Studio and Visual Studio Express. This is accessed from right-clicking on your project and clicking Manage NuGet Packages.
NuGet is an open source Library Package Manager that comes as a Visual Studio extension and that makes it very easy to add, remove, and update external libraries in your Visual Studio projects and websites. Beginning ASP.NET 4.5 in C# and VB.NET, WROX, 2013
Once installed, a new Folder group will appear in your Solution Explorer called Scripts
. Simply drag and drop the file you wish to include onto your page of choice.
This method is ideal for larger projects because if you choose to remove the files, or change versions later (though the package manager) if will automatically remove/update any reference to that file within your project.
The only downside to this approach is it does not use a CDN to host the file so page load time may be slightly slower the first time the user visits your site.
See the Locale.getLanguage()
, Locale.getCountry()
... Store this combination in the database instead of the "programatic name"
...
When you want to build the Locale back, use public Locale(String language, String country)
Here is a sample code :)
// May contain simple syntax error, I don't have java right now to test..
// but this is a bigger picture for your algo...
public String localeToString(Locale l) {
return l.getLanguage() + "," + l.getCountry();
}
public Locale stringToLocale(String s) {
StringTokenizer tempStringTokenizer = new StringTokenizer(s,",");
if(tempStringTokenizer.hasMoreTokens())
String l = tempStringTokenizer.nextElement();
if(tempStringTokenizer.hasMoreTokens())
String c = tempStringTokenizer.nextElement();
return new Locale(l,c);
}
this is the only way i can think of doing it.
//positive to minus
int a = 5; // starting with 5 to become -5
int b = int a * 2; // b = 10
int c = a - b; // c = - 5;
std::cout << c << endl;
//outputs - 5
//minus to positive
int a = -5; starting with -5 to become 5
int b = a * 2;
// b = -10
int c = a + b
// c = 5
std::cout << c << endl;
//outputs 5
Function examples
int b = 0;
int c = 0;
int positiveToNegative (int a) {
int b = a * 2;
int c = a - b;
return c;
}
int negativeToPositive (int a) {
int b = a * 2;
int c = a + b;
return c;
}
One of recent the TFS Rocks pocasts mentioned such an organisation, may have been number 16.
I had trouble using the above, and I needed the IP address from a controller. I used the following in the end:

Normally, When you copy a cell you will find the below statement written down in the status bar (in the bottom of your sheet)
"Select destination and Press Enter or Choose Paste"
Then you press whether Enter or choose paste to paste the value of the cell.
If you didn't press Esc afterwards you will be able to paste the value of the cell several times
Application.CutCopyMode = False does the same like the Esc button, if you removed it from your code you will find that you are able to paste the cell value several times again.
And if you closed the Excel without pressing Esc you will get the warning 'There is a large amount of information on the Clipboard....'
import("time")
layout := "2006-01-02T15:04:05.000Z"
str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(layout, str)
if err != nil {
fmt.Println(err)
}
fmt.Println(t)
gives:
>> 2014-11-12 11:45:26.371 +0000 UTC
To squabble about the performance of binary-trees is meaningless - they are not a data structure, but a family of data structures, all with different performance characteristics. While it is true that unbalanced binary trees perform much worse than self-balancing binary trees for searching, there are many binary trees (such as binary tries) for which "balancing" has no meaning.
map
and set
objects in many languages' libraries.The reason that binary trees are used more often than n-ary trees for searching is that n-ary trees are more complex, but usually provide no real speed advantage.
In a (balanced) binary tree with m
nodes, moving from one level to the next requires one comparison, and there are log_2(m)
levels, for a total of log_2(m)
comparisons.
In contrast, an n-ary tree will require log_2(n)
comparisons (using a binary search) to move to the next level. Since there are log_n(m)
total levels, the search will require log_2(n)*log_n(m)
= log_2(m)
comparisons total. So, though n-ary trees are more complex, they provide no advantage in terms of total comparisons necessary.
(However, n-ary trees are still useful in niche-situations. The examples that come immediately to mind are quad-trees and other space-partitioning trees, where divisioning space using only two nodes per level would make the logic unnecessarily complex; and B-trees used in many databases, where the limiting factor is not how many comparisons are done at each level but how many nodes can be loaded from the hard-drive at once)
Just put this in the first line of your script :
#!/usr/bin/env python
Make the file executable with
chmod +x myfile.py
Execute with
./myfile.py
Today I faced the same issue consistently, whenever I exit the eclipse. While trying the above solution provided by TS.xy, the below steps got rid of this issue for now.
Hope that this step may work for someone.
Here is an alternative.
var condition = true;
var props = {
value: 'foo',
...( condition && { disabled: true } )
};
var component = <div { ...props } />;
Or its inline version
var condition = true;
var component = (
<div
value="foo"
{ ...( condition && { disabled: true } ) } />
);
Here's a hint, you have a graph of nodes in the linked list, and you always keep a reference to head which is the first node in the linkedList.
next points to the next node in the linkedlist, so when next is null you are at the end of the list.
You can find documentation here.
Based on your requirement you can try according option.
to ellipsize, a neologism, means to shorten text using an ellipsis, i.e. three dots ...
or more commonly ligature …
, to stand in for the omitted bits.
Say original value pf text view is aaabbbccc and its fitting inside the view
start
's output will be : ...bccc
end
's output will be : aaab...
middle
's output will be : aa...cc
marquee
's output will be : aaabbbccc auto sliding from right to left
The equivalent of LIMIT
is SET ROWCOUNT
, but if you want generic pagination it's better to write a query like this:
;WITH Results_CTE AS
(
SELECT
Col1, Col2, ...,
ROW_NUMBER() OVER (ORDER BY SortCol1, SortCol2, ...) AS RowNum
FROM Table
WHERE <whatever>
)
SELECT *
FROM Results_CTE
WHERE RowNum >= @Offset
AND RowNum < @Offset + @Limit
The advantage here is the parameterization of the offset and limit in case you decide to change your paging options (or allow the user to do so).
Note: the @Offset
parameter should use one-based indexing for this rather than the normal zero-based indexing.

The suggested solutions could be optimized using commons.io, handling the error stream, and using Exceptions. I would suggest to wrap like this for use in Java 8 or later:
public static List<String> execute(final String command) throws ExecutionFailedException, InterruptedException, IOException {
try {
return execute(command, 0, null, false);
} catch (ExecutionTimeoutException e) { return null; } /* Impossible case! */
}
public static List<String> execute(final String command, final long timeout, final TimeUnit timeUnit) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException {
return execute(command, 0, null, true);
}
public static List<String> execute(final String command, final long timeout, final TimeUnit timeUnit, boolean destroyOnTimeout) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException {
Process process = new ProcessBuilder().command("bash", "-c", command).start();
if(timeUnit != null) {
if(process.waitFor(timeout, timeUnit)) {
if(process.exitValue() == 0) {
return IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8);
} else {
throw new ExecutionFailedException("Execution failed: " + command, process.exitValue(), IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8));
}
} else {
if(destroyOnTimeout) process.destroy();
throw new ExecutionTimeoutException("Execution timed out: " + command);
}
} else {
if(process.waitFor() == 0) {
return IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8);
} else {
throw new ExecutionFailedException("Execution failed: " + command, process.exitValue(), IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8));
}
}
}
public static class ExecutionFailedException extends Exception {

The best way for DateTime is use a Trigger:
/************ ROLE ************/
drop table if exists `role`;
create table `role` (
`id_role` bigint(20) unsigned not null auto_increment,
`date_created` datetime,
`date_deleted` datetime,
`name` varchar(35) not null,
`description` text,
primary key (`id_role`)
) comment='';
drop trigger if exists `role_date_created`;
create trigger `role_date_created` before insert
on `role`
for each row
set new.`date_created` = now();
You've got one truly marvelous answer from ray023, but your comment that it's probably overkill is apt. For a "lighter" version....
Block 1 is, IMHO, bad practice. As already pointed out by osknows, mixing error-handling with normal-path code is Not Good. For one thing, if a new error is thrown while there's an Error condition in effect you will not get an opportunity to handle it (unless you're calling from a routine that also has an error handler, where the execution will "bubble up").
Block 2 looks like an imitation of a Try/Catch block. It should be okay, but it's not The VBA Way. Block 3 is a variation on Block 2.
Block 4 is a bare-bones version of The VBA Way. I would strongly advise using it, or something like it, because it's what any other VBA programmer inherting the code will expect. Let me present a small expansion, though:
Private Sub DoSomething()
On Error GoTo ErrHandler
'Dim as required
'functional code that might throw errors
ExitSub:
'any always-execute (cleanup?) code goes here -- analagous to a Finally block.
'don't forget to do this -- you don't want to fall into error handling when there's no error
Exit Sub
ErrHandler:
'can Select Case on Err.Number if there are any you want to handle specially
'display to user
MsgBox "Something's wrong: " & vbCrLf & Err.Description
'or use a central DisplayErr routine, written Public in a Module
DisplayErr Err.Number, Err.Description
Resume ExitSub
Resume
End Sub
Note that second Resume
. This is a trick I learned recently: It will never execute in normal processing, since the Resume <label>
statement will send the execution elsewhere. It can be a godsend for debugging, though. When you get an error notification, choose Debug (or press Ctl-Break, then choose Debug when you get the "Execution was interrupted" message). The next (highlighted) statement will be either the MsgBox
or the following statement. Use "Set Next Statement" (Ctl-F9) to highlight the bare Resume
, then press F8. This will show you exactly where the error was thrown.
As to your objection to this format "jumping around", A) it's what VBA programmers expect, as stated previously, & B) your routines should be short enough that it's not far to jump.

Try this please. I checked it and it's working:
SELECT *
FROM Table
WHERE ARIDNR IN (
SELECT ARIDNR
FROM Table
GROUP BY ARIDNR
HAVING COUNT(distinct LIEFNR) > 1
)
This post contains a brilliant trick to detect where the cascade problem is:
Try to replace on Cascade at the time with Cascade.None()
until you do not get the error and then you have detected the cascade causing the problem.
Then solve the problem either by changing the original cascade to something else or using Tom Anderson answer.
string[] result = new string[table.Columns.Count];
DataRow dr = table.Rows[0];
for (int i = 0; i < dr.ItemArray.Length; i++)
{
result[i] = dr[i].ToString();
}
foreach (string str in result)
Console.WriteLine(str);
First of all, you need to check that the IIS is installed in your machine, for that you can go to:
Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'
If not, check it, and Press Accept to install it.
Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).
Edit: You should have something like this:
Suppose I create a new file, newFile.txt
:
Suppose I add the file accidentally, git add newFile.txt
:
Now I want to undo this add, before commit, git reset newFile.txt
:
list.clear()
is going to keep the same ArrayList but the same memory allocation. list = new ArrayList<int>();
is going to allocate new memory for your ArrayList.
The big difference is that ArrayLists will expand dynamically as you need more space. Therefore, if you call list.clear()
you will still, potentially, have a large amount of memory allocated for an ArrayList that might not be needed.
That said list.clear()
will be faster but if memory maters you might want to allocate a new ArrayList.
jQuery datepicker
is good option
An example using built in TimeUnit
.
long uptime = System.currentTimeMillis();
long days = TimeUnit.MILLISECONDS
.toDays(uptime);
uptime -= TimeUnit.DAYS.toMillis(days);
long hours = TimeUnit.MILLISECONDS
.toHours(uptime);
uptime -= TimeUnit.HOURS.toMillis(hours);
long minutes = TimeUnit.MILLISECONDS
.toMinutes(uptime);
uptime -= TimeUnit.MINUTES.toMillis(minutes);
long seconds = TimeUnit.MILLISECONDS
.toSeconds(uptime);
What is happening here is that database route does not accept any url methods.
I would try putting the url methods in the app route just like you have in the entry_page function:
@app.route('/entry', methods=['GET', 'POST'])
def entry_page():
if request.method == 'POST':
date = request.form['date']
title = request.form['blog_title']
post = request.form['blog_main']
post_entry = models.BlogPost(date = date, title = title, post = post)
db.session.add(post_entry)
db.session.commit()
return redirect(url_for('database'))
else:
return render_template('entry.html')
@app.route('/database', methods=['GET', 'POST'])
def database():
query = []
for i in session.query(models.BlogPost):
query.append((i.title, i.post, i.date))
return render_template('database.html', query = query)
Inspired by DanSalmo's comment, here is a solution that is concise, elegant, and at the same time is one of the fastest solutions.
good, bad = [], []
for item in my_list:
good.append(item) if item in set(goodvals) else bad.append(item)
Tip: Turning goodval
into a set gives us an easy 40% speed boost.
If you have the need for maximum speed, we take the fastest answer and turbocharge it by turning good_list into a set. That gives us a 45% speed boost, and we end up with a solution that is more than 5.5x as fast as the slowest solution, even while it remains readable.
good_list_set = set(good_list) # 45% faster than a tuple.
good, bad = [], []
for item in my_origin_list:
if item in good_list_set:
good.append(item)
else:
bad.append(item)
A little shorter:
good_list_set = set(good_list) # 45% faster than a tuple.
good, bad = [], []
for item in my_origin_list:
out = good if item in good_list_set else bad
out.append(item)
Elegance can be somewhat subjective, but some of the Rube Goldberg style solutions that are cute and ingenious are quite concerning and should not be used in production code in any language, let alone python which is elegant at heart.

Another Really simple Solution is using the library Newtonsoft.Json:
User user = JsonConvert.DeserializeObject<User>(jsonString);
If at least one of the remote IPs is already known, static and dedicated to talk only to one of your apps, you may use iptables rule (table nat, chain PREROUTING) to redirect incomming traffic from this address to "shared" local port to any other port where the appropriate application actually listen.
Another way is using CTE
:
;WITH cte
AS (SELECT *
FROM workrecord2 w
WHERE EXISTS (SELECT 1
FROM employee e
WHERE employeerun = employeeno
AND company = '1'
AND date = '2013-05-06'))
DELETE FROM cte
Note: We cannot use JOIN
inside CTE
when you want to delete

That 2GB
limit you see is the total memory of the VM in which docker runs.
If you are using docker-for-windows or docker-for-mac you can easily increase it from the Whale icon in the task bar, then go to Preferences -> Advanced:
But if you are using VirtualBox behind, open VirtualBox, Select and configure the docker-machine assigned memory.
See this for Mac:
https://docs.docker.com/docker-for-mac/#memory
MEMORY By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. You can increase the RAM on the app to get faster performance by setting this number higher (for example to 3) or lower (to 1) if you want Docker for Mac to use less memory.

As far as the Python languages is concerned, _

or _f_o_o_
.
Any special meaning of _

A dummy name when a variable is not intended to be used, but a name is required by syntax/semantics.

sum(1 for _ in some_iterable)
# unpacking disregarding specific elements
head, *_ = values
# function disregarding its argument

Many REPLs/shells store the result of the last top-level expression to builtins._

The special identifier
_
is used in the interactive interpreter to store the result of the last evaluation; it is stored in thebuiltins
module. When not in interactive mode,_

If you are using EF, adorn the property with Data Annotation [Timestamp], then go to the overrided OnModelCreating, inside your context class, and add this Fluent API code:
modelBuilder.Entity<YourEntity>()
.Property(b => b.Timestamp)
.ValueGeneratedOnAddOrUpdate()
.IsConcurrencyToken()
.ForSqliteHasDefaultValueSql("CURRENT_TIMESTAMP");
It will make a default value to every data that will be insert into this table.
pip install --ignore-installed --upgrade --user tensorflow==2.0.1
Here 2.0.1 is the version of tensorflow.
you can also write the code below.
Array lbl_array = Array.CreateInstance(typeof(string), i, j);
where 'i' is the number of rows and 'j' is the number of columns. using the 'typeof(..)' method you can choose the type of your array i.e. int, string, double
Its simple If you are passing String X from A to B.
A--> B
In Activity A
1) Create Intent
2) Put data in intent using putExtra method of intent
3) Start activity
Intent i = new Intent(A.this, B.class);
i.putExtra("MY_kEY",X);
In Activity B
inside onCreate method
1) Get intent object
2) Get stored value using key(MY_KEY)
Intent intent = getIntent();
String result = intent.getStringExtra("MY_KEY");
This is the standard way to send data from A to B. you can send any data type, it could be int, boolean, ArrayList, String[]. Based on the datatype you stored in Activity as key, value pair retrieving method might differ like if you are passing int value then you will call
intent.getIntExtra("KEY");
You can even send Class objects too but for that, you have to make your class object implement the Serializable or Parceable interface.
How much data you can send across size. If data exceeds a certain amount in size then you might get TransactionTooLargeException. Suppose you are trying to send bitmap across the activity and if the size exceeds certain data size then you might see this exception.
Change the content type to ms-excel in the html and browser shall open the html in the Excel as xls. If you want control over the transformation of HTML to excel use POI libraries to do so.
Here is one case that worked for me if we need to convert .cer to .crt, though both of them are contextually same
openssl pkcs12 -in identity.p12 -nokeys -out mycertificate.crt
where we should have a valid private key (identity.p12) PKCS 12 format, this one i generated from keystore (.jks file) provided by CA (Certification Authority) who created my certificate.
Typically, I store a TimeSpan as a bigint populated with ticks from the TimeSpan.Ticks property as previously suggested. You can also store a TimeSpan as a varchar(26) populated with the output of TimeSpan.ToString(). The four scalar functions (ConvertFromTimeSpanString, ConvertToTimeSpanString, DateAddTicks, DateDiffTicks) that I wrote are helpful for handling TimeSpan on the SQL side and avoid the hacks that would produce artificially bounded ranges. If you can store the interval in a .NET TimeSpan at all it should work with these functions also. Additionally, the functions allow you to work with TimeSpans and 100-nanosecond ticks even when using technologies that don't include the .NET Framework.

I don't recommend doing DOM manipulations inside a loop -- that can get expensive in large datasets. Instead, I would do something like this:
var elMainSelect = document.getElementById('mainSelect');
function selectOptionsCreate() {
var frag = document.createDocumentFragment(),
elOption;
for (var i=12; i<101; ++i) {
elOption = frag.appendChild(document.createElement('option'));
elOption.text = i;
}
elMainSelect.appendChild(frag);
}
You can read more about DocumentFragment on MDN, but here's the gist of it:
It is used as a light-weight version of Document to store a segment of a document structure comprised of nodes just like a standard document. The key difference is that because the document fragment isn't part of the actual DOM's structure, changes made to the fragment don't affect the document, cause reflow, or incur any performance impact that can occur when changes are made.
There are some predefined formats in date_d.php
to use with format
like:
define ('DATE_ATOM', "Y-m-d\TH:i:sP");
define ('DATE_COOKIE', "l, d-M-y H:i:s T");
define ('DATE_ISO8601', "Y-m-d\TH:i:sO");
define ('DATE_RFC822', "D, d M y H:i:s O");
define ('DATE_RFC850', "l, d-M-y H:i:s T");
define ('DATE_RFC1036', "D, d M y H:i:s O");
define ('DATE_RFC1123', "D, d M Y H:i:s O");
define ('DATE_RFC2822', "D, d M Y H:i:s O");
define ('DATE_RFC3339', "Y-m-d\TH:i:sP");
define ('DATE_RSS', "D, d M Y H:i:s O");
define ('DATE_W3C', "Y-m-d\TH:i:sP");
Use like this:
$date = new \DateTime();
$string = $date->format(DATE_RFC2822);
To change color of UINavigationBar
title the correct way use this code:
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];
UITextAttributeTextColor
is deprecated in lastest ios 7 version. Use NSForegroundColorAttributeName
instead.
I would first create a DataTable
with the columns that you require, then populate it via Linq-to-XML.
You could use a Select query to create an object that represents each row, then use the standard approach for creating DataRows for each item ...
class Quest
{
public string Answer1;
public string Answer2;
public string Answer3;
public string Answer4;
}
public static void Main()
{
var doc = XDocument.Load("filename.xml");
var rows = doc.Descendants("QuestId").Select(el => new Quest
{
Answer1 = el.Element("Answer1").Value,
Answer2 = el.Element("Answer2").Value,
Answer3 = el.Element("Answer3").Value,
Answer4 = el.Element("Answer4").Value,
});
// iterate over the rows and add to DataTable ...
}
select A, B, 'c' as C
from MyTable
dim mydate = from cv in mydata.t1s
select cv.date1 asc
datetime mindata = mydate[0];
To load other file(css ,js) and folder(images) , in codeigniter project
we have to follow two simple step:
1.create folder public (can give any name) in your codeigniters folder put your bootstrap files css and js folder in side public folder. https://i.stack.imgur.com/O2gr6.jpg
2.now we have to use two line of code 1.load->helper('url'); ?> 2.
go to your view file
put first line to load base URL
<?php $this->load->helper('url'); ?>
secondly in your html head tag put this
<link rel="stylesheet" type="text/css" href="<?php echo base_url(); ?>/public/css/bootstrap.css">
now you can enjoy the bootstrap in your codeigniter
I'm not fully sure that this is what you're looking for, but if your question is how to read an integer using <stdio.h>
, then the proper syntax is
int myInt;
scanf("%d", &myInt);
You'll need to do a lot of error-handling to ensure that this works correctly, of course, but this should be a good start. In particular, you'll need to handle the cases where
stdin
file is closed or broken, so you get nothing at all.To check for this, you can capture the return code from scanf
like this:
int result = scanf("%d", &myInt);
If stdin
encounters an error while reading, result
will be EOF
, and you can check for errors like this:
int myInt;
int result = scanf("%d", &myInt);
if (result == EOF) {
/* ... you're not going to get any input ... */
}
If, on the other hand, the user enters something invalid, like a garbage text string, then you need to read characters out of stdin
until you consume all the offending input. You can do this as follows, using the fact that scanf
returns 0 if nothing was read:
int myInt;
int result = scanf("%d", &myInt);
if (result == EOF) {
/* ... you're not going to get any input ... */
}
if (result == 0) {
while (fgetc(stdin) != '\n') // Read until a newline is found
;
}
Hope this helps!
EDIT: In response to the more detailed question, here's a more appropriate answer. :-)
The problem with this code is that when you write
printf("got the number: %d", scanf("%d", &x));
This is printing the return code from scanf
, which is EOF
on a stream error, 0
if nothing was read, and 1
otherwise. This means that, in particular, if you enter an integer, this will always print 1
because you're printing the status code from scanf
, not the number you read.
To fix this, change this to
int x;
scanf("%d", &x);
/* ... error checking as above ... */
printf("got the number: %d", x);
Hope this helps!
Anwer here is simple i.e run the loop 'n' times.
n=int(input())
count=0
i=2
while count<n:
flag=0
j=2
while j<=int(i**0.5):
if i%j==0:
flag+=1
j+=1
if flag==0:
print(i,end=" ")
count+=1
i+=1
Go here :
C:\Program Files (x86)\Windows Kits\10
and do whatever you were supposed to go in the given directory for VS 13.
in the lib folder, you will find some versions, I copied the 32-bit glut.lib files in amd and x86 and 64-bit glut.lib in arm64 and x64 directories in um
folder for every version that I could find.
That worked for me.
EDIT : I tried this in windows 10, maybe you need to go to C:\Program Files (x86)\Windows Kits\8.1
folder for windows 8/8.1.
I didn't really like any of these answers as a whole. If you have a class (say printableArea) and have that as an immediate child of body, then you can do something like this in your print CSS:
body > *:not(.printableArea) {
display: none;
}
//Not needed if already showing
body > .printableArea {
display: block;
}
For those looking for printableArea in another place, you would need to make sure the parents of printableArea are shown:
body > *:not(.parentDiv),
.parentDiv > *:not(.printableArea) {
display: none;
}
//Not needed if already showing
body > .printableArea {
display: block;
}
Using the visibility can cause a lot of spacing issues and blank pages. This is because the visibility maintains the elements space, just makes it hidden, where as display removes it and allows other elements to take up its space.
The reason why this solution works is that you are not grabbing all elements, just the immediate children of body and hiding them. The other solutions below with display css, hide all the elements, which effects everything inside of printableArea content.
I wouldn't suggest javascript as you would need to have a print button that the user clicks and the standard browser print buttons wouldn't have the same effect. If you really need to do that, what I would do is store the html of body, remove all unwanted elements, print, then add the html back. As mentioned though, I would avoid this if you can and use a CSS option like above.
NOTE: You can add whatever CSS into the print CSS using inline styles:
<style type="text/css">
@media print {
//styles here
}
</style>
Or like I usually use is a link tag:
<link rel="stylesheet" type="text/css" media="print" href="print.css" />

Unless you have some really compelling reason not to, I suggest ditching the MS JDBC driver.
Instead, use the jtds jdbc driver. Read the README.SSO file in the jtds distribution on how to configure for single-sign-on (native authentication) and where to put the native DLL to ensure it can be loaded by the JVM.
If there are up to 10 strings then you should use a list in order to iterate through all values.
{% set list1 = variable1.split(';') %}
{% for list in list1 %}
<p>{{ list }}</p>

This is what css is for... HTML doesn't allow for unequal padding. When you say that you don't want to use style sheets, does this mean you're OK with inline css?
<table>
<tr>
<td style="padding: 5px 10px 5px 5px;">Content</td>
<td style="padding: 5px 10px 5px 5px;">Content</td>
</tr>
</table>
You could also use JS to do this if you're desperate not to use stylesheets for some reason.
I think adding try/catch for every SaveChanges()
operation is not a good practice, it's better to centralize this :
Add this class to the main DbContext
class :
public override int SaveChanges()
{
try
{
return base.SaveChanges();
}
catch (DbEntityValidationException ex)
{
string errorMessages = string.Join("; ", ex.EntityValidationErrors.SelectMany(x => x.ValidationErrors).Select(x => x.ErrorMessage));
throw new DbEntityValidationException(errorMessages);
}
}
This will overwrite your context's SaveChanges()
method and you'll get a comma separated list containing all the entity validation errors.
this also can improved, to log errors in production env, instead of just throwing an error.
hope this is helpful.
The issue is with this line
xlo.Worksheets(1).Cells(2, 2) = TextBox1.Text
You have the textbox defined at some other location which you are not using here. Excel is unable to find the textbox object in the current sheet while this textbox was defined in xlw.
Hence replace this with
xlo.Worksheets(1).Cells(2, 2) = worksheets("xlw").TextBox1.Text

You should drop the old table type and create a new one. However if it has any dependencies (any stored procedures using it) you won't be able to drop it. I've posted another answer on how to automate the process of temporary dropping all stored procedures, modifying the table table and then restoring the stored procedures.
You can use the ui
object provided to the events, specifically you want the stop
event, the ui.item
property and .index()
, like this:
$("#sortable").sortable({
stop: function(event, ui) {
alert("New position: " + ui.item.index());
}
});
You can see a working demo here, remember the .index()
value is zero-based, so you may want to +1 for display purposes.
Chrome needs a user interaction for the video to be autoplayed or played via js (video.play()). But the interaction can be of any kind, in any moment. If you just click random on the page, the video will autoplay. I resolved then, adding a button (only on chrome browsers) that says "enable video autoplay". The button does nothing, but just clicking it, is the required user interaction for any further video.

Because we have two NumPy installations in the system. One is installed by Homebrew and the second is installed by pip. So in order to solve the problem, we need to delete one and use the default NumPy install by OpenCV.
Check the path,
import numpy
print numpy.__path__
and manually delete it using rm
.
Here’s another algorithm for ensuring the numbers are unique:
Compared to the method of generating random numbers until you get a unique one, this method uses more memory, but it has a more stable running time – the results are guaranteed to be found in finite time. This method works better if the upper limit is relatively low or if the amount to take is relatively high.
My answer uses the Lodash library for simplicity, but you could also implement the algorithm described above without that library.
// assuming _ is the Lodash library
// generates `amount` numbers from 0 to `upperLimit` inclusive
function uniqueRandomInts(upperLimit, amount) {
var possibleNumbers = _.range(upperLimit + 1);
var shuffled = _.shuffle(possibleNumbers);
return shuffled.slice(0, amount);
}
The easier way to accept all accents is this:
[A-zÀ-ú] // accepts lowercase and uppercase characters
[A-zÀ-ÿ] // as above but including letters with an umlaut (includes [ ] ^ \ × ÷)
[A-Za-zÀ-ÿ] // as above but not including [ ] ^ \
[A-Za-zÀ-ÖØ-öø-ÿ] // as above but not including [ ] ^ \ × ÷
See https://unicode-table.com/en/ for characters listed in numeric order.
Suppose you have a hidden input, named XXX, if you want to assign a value to the following
<script type="text/javascript">
$(document).ready(function(){
$('#XXX').val('any value');
})
</script>
This design was not mentioned yet:
Though it has limitations, if you can bear them, it's very simple and very efficient. Features:
Here follows an example - taxonomic tree of birds so the hierarchy is Class/Order/Family/Genus/Species - species is the lowest level, 1 row = 1 taxon (which corresponds to species in the case of the leaf nodes):
CREATE TABLE `taxons` (
`TaxonId` smallint(6) NOT NULL default '0',
`ClassId` smallint(6) default NULL,
`OrderId` smallint(6) default NULL,
`FamilyId` smallint(6) default NULL,
`GenusId` smallint(6) default NULL,
`Name` varchar(150) NOT NULL default ''
);
and the example of the data:
+---------+---------+---------+----------+---------+-------------------------------+
| TaxonId | ClassId | OrderId | FamilyId | GenusId | Name |
+---------+---------+---------+----------+---------+-------------------------------+
| 254 | 0 | 0 | 0 | 0 | Aves |
| 255 | 254 | 0 | 0 | 0 | Gaviiformes |
| 256 | 254 | 255 | 0 | 0 | Gaviidae |
| 257 | 254 | 255 | 256 | 0 | Gavia |
| 258 | 254 | 255 | 256 | 257 | Gavia stellata |
| 259 | 254 | 255 | 256 | 257 | Gavia arctica |

| 263 | 254 | 262 | 0 | 0 | Podicipedidae |
| 264 | 254 | 262 | 263 | 0 | Tachybaptus |
This is great because this way you accomplish all the needed operations in a very easy way, as long as the internal categories don't change their level in the tree.
You're right, see 3.1.3. Unicode Strings.
It's been the syntax since Python 2.0.
Python 3 made them redundant, as the default string type is Unicode. Versions 3.0 through 3.2 removed them, but they were re-added in 3.3+ for compatibility with Python 2 to aide the 2 to 3 transition.
In pretty much all modern languages, null logically refers to pointers (or references) not having a value, or a variable that is not initialized. 0 is the integer value of zero, and false is the boolean value of, well, false. To make things complicated, in C, for example, null, 0, and false are all represented the exact same way. I don't know how it works in PHP.
Then, to complicate things more, databases have a concept of null, which means missing or not applicable, and most languages don't have a direct way to map a DBNull to their null. Until recently, for example, there was no distinction between an int being null and being zero, but that was changed with nullable ints.
Sorry to make this sound complicated. It's just that this has been a harry sticking point in languages for years, and up until recently, it hasn't had any clear resolution anywhere. People used to just kludge things together or make blank or 0 represent nulls in the database, which doesn't always work too well.
I was able to achieve this result using the Jenkins Dynamic Parameter Plug-in. I used the Dynamic Choice Parameter option and, for the choices script, I used the following:
proc1 = ['/bin/bash', '-c', "/usr/bin/git ls-remote -h ssh://[email protected]/path/to/repo.git"].execute()
proc2 = ['/bin/bash', '-c', "awk '{print \$2}'"].execute()
proc3 = ['/bin/bash', '-c', "sed s%^refs/heads%origin%"].execute()
all = proc1 | proc2 | proc3
String result = all.text
String filename = "/tmp/branches.txt"
boolean success = new File(filename).write(result)
def multiline = "cat /tmp/branches.txt".execute().text
def list = multiline.readLines()
You can add function to:

I know that question is a bit old but

Use a Spannable String
String s= "Hello Everyone";
SpannableString ss1= new SpannableString(s);
ss1.setSpan(new RelativeSizeSpan(2f), 0,5, 0); // set size
ss1.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);// set color
TextView tv= (TextView) findViewById(R.id.textview);
tv.setText(ss1);

You can split string using space and add span to the string you require.
String s= "Hello Everyone";
String[] each = s.split(" ");
Now apply span
to the string
and add the same to textview
.
If your cron job is running on Mac OS X only, you may want to use launchd instead.
From Scheduling Timed Jobs (official Apple docs):
Note: Although it is still supported, cron is not a recommended solution. It has been deprecated in favor of launchd.
You can find additional information (such as the launchd Wikipedia page) with a simple web search.
Instead of using sed
to filter out the certificate, you can also pipe the openssl s_client
output through openssl x509 -out certfile.txt
, for example:
echo "" | openssl s_client -connect my.server.com:443 -showcerts 2>/dev/null | openssl x509 -out certfile.txt
Use facebook feed dialog instead of share dialog.
Example:
Benjamin Bannier's answer yields a pass-through when the median of distances from the median is 0, so I found this modified version a bit more helpful for cases as given in the example below.
def reject_outliers_2(data, m=2.):
d = np.abs(data - np.median(data))
mdev = np.median(d)
s = d / (mdev if mdev else 1.)
return data[s < m]
Example:
data_points = np.array([10, 10, 10, 17, 10, 10])
print(reject_outliers(data_points))
print(reject_outliers_2(data_points))
Gives:
[[10, 10, 10, 17, 10, 10]] # 17 is not filtered
[10, 10, 10, 10, 10] # 17 is filtered (it's distance, 7, is greater than m)

You can't truly do it in "standard" C, because the size of an int and of a char aren't fixed. Let's say you are using a compiler under Windows or Linux on an intel PC...
int i = 5; char a = ((char*)&i)[0]; char b = ((char*)&i)[1];
Remember of endianness of your machine! And that int are "normally" 32 bits, so 4 chars!
But you probably meant "i want to stringify a number", so ignore this response :-)
This is the fastest way:
if ($coll->isEmpty()) {...}
Other solutions like count
do a bit more than you need which costs slightly more time.
Plus, the isEmpty()
name quite precisely describes what you want to check there so your code will be more readable.
Let yet add up to the answer from @Drew Noakes:
"C:\Program Files\Git\git-bash.exe" --cd=C:\GitRepo
The cd
param should be one of the options how to specify the working directory.
Also notice, that I have not any --login
param there: Instead, I use another extra app, dedicated just for SSH keys: Pageant (PuTTY authentication agent).
C:\GitRepo
The same possible way, as @Drew Noakes mentioned/shown here sooner, I use it too.
Ctrl + Alt + B
Such shortcuts are another less known feature in Windows. But there is a restriction: To let the shortcut take effect, it must be placed somewhere on the User's subdirectory: The Desktop is fine.
If you do not want it visible, yet still activatable, place this .lnk

For HttpClient, we can do this :
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], new TrustManager[] {new DefaultTrustManager()}, new SecureRandom());
SSLContext.setDefault(ctx);
String uri = new StringBuilder("url").toString();
HostnameVerifier hostnameVerifier = new HostnameVerifier() {
@Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
};
HttpClient client = HttpClientBuilder.create().setSSLContext(ctx)
.setSSLHostnameVerifier(hostnameVerifier).build()
Take a look at numpy.reshape .
>>> arr = numpy.zeros((50,100,25))
>>> arr.shape
# (50, 100, 25)
>>> new_arr = arr.reshape(5000,25)
>>> new_arr.shape
# (5000, 25)
# One shape dimension can be -1.
# In this case, the value is inferred from
# the length of the array and remaining dimensions.
>>> another_arr = arr.reshape(-1, arr.shape[-1])
>>> another_arr.shape
# (5000, 25)
While a few of these answers will get you in the ballpark, you cannot do what you're trying to do with arbitrary dates for SqlServer 2005 and earlier because of daylight savings time. Using the difference between the current local and current UTC will give me the offset as it exists today. I have not found a way to determine what the offset would have been for the date in question.
That said, I know that SqlServer 2008 provides some new date functions that may address that issue, but folks using an earlier version need to be aware of the limitations.
Our approach is to persist UTC and perform the conversion on the client side where we have more control over the conversion's accuracy.
The simplest, and best long-term solution
Go to the main menu on top of Eclipse and locate Window next to Run and expand it.
Window->Reset Perspective... to restore all views to their defaults
It will reset the default setting.
The easiest way i tired in xcode 4.52 was to create an additional view and connect them by using segue modal(control drag the button from view one to the second view, chose Modal). Then drag in a button to second view or the modal view that you created. Control and drag this button to the header file and use action connection. This will create an IBaction in your controller.m file. Find your button action type in the code.

You should use var keyword unless you intend to have the variable attached to window object in browser. Here's a link that explains scoping and difference between glocal scoping and local scoping with and wihtout var keyword.
When variables get defined without the use of var keyword, what it looks like is a simple “assignment” operation.
When the value is assigned to a variable in javascript, the interpreter first tries to find the “variable declaration” in the same context/scope as that of assignment. When the interpreter executes dummyVariable = 20
, it looks up for the declaration of dummyVariable at beginning of the function.
(Since all Variable declarations are moved to the beginning of the context by javascript interpreter and this is called hoisting)
You may also want to look at hoisting in javascript
I've always considered throwing checked exceptions in the constructor to be bad practice, or at least something that should be avoided.
The reason for this is that you cannot do this :
private SomeObject foo = new SomeObject();
Instead you must do this :
private SomeObject foo;
public MyObject() {
try {
foo = new SomeObject()
} Catch(PointlessCheckedException e) {
throw new RuntimeException("ahhg",e);
}
}
At the point when I'm constructing SomeObject I know what it's parameters are so why should I be expected to wrap it in a try catch? Ahh you say but if I'm constructing an object from dynamic parameters I don't know if they're valid or not. Well, you could... validate the parameters before passing them to the constructor. That would be good practice. And if all you're concerned about is whether the parameters are valid then you can use IllegalArgumentException.
So instead of throwing checked exceptions just do
public SomeObject(final String param) {
if (param==null) throw new NullPointerException("please stop");
if (param.length()==0) throw new IllegalArgumentException("no really, please stop");
}
Of course there are cases where it might just be reasonable to throw a checked exception
public SomeObject() {
if (todayIsWednesday) throw new YouKnowYouCannotDoThisOnAWednesday();
}
But how often is that likely?
data d is in row 0 and column 3 for value d :
DataTable table;
String d = (String)table.Rows[0][3];
From the documentation:
contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')
Type: String
When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.
and:
dataType (default: Intelligent Guess (xml, json, script, or html))
Type: String
The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).
They're essentially the opposite of what you thought they were.
Try obj2fd => https://www.npmjs.com/package/obj2fd
import obj2fd from 'obj2fd'
let data = {a:1, b:2, c:{ca:1}};
let dataWithFormData = obj2fd(data);
//result => [a=>1, b=>2, c=>[ca=>1]]
I couldn't get it to work using dmyung's solution, it gave me an exception when getting either the message id or thread id.
In the end, I've used the following method to get the thread id:
private long getThreadId(Context context) {
long threadId = 0;
String SMS_READ_COLUMN = "read";
String WHERE_CONDITION = SMS_READ_COLUMN + " = 0";
String SORT_ORDER = "date DESC";
int count = 0;
Cursor cursor = context.getContentResolver().query(
SMS_INBOX_CONTENT_URI,
new String[] { "_id", "thread_id", "address", "person", "date", "body" },
WHERE_CONDITION,
null,
SORT_ORDER);
if (cursor != null) {
try {
count = cursor.getCount();
if (count > 0) {
cursor.moveToFirst();
threadId = cursor.getLong(1);
}
} finally {
cursor.close();
}
}
return threadId;
}
Then I could delete it. However, as Doug said, the notification is still there, even the message is displayed when opening the notification panel. Only when tapping the message I could actually see that it's empty.
So I guess the only way this would work would be to actually somehow intercept the SMS before it's delivered to the system, before it even reaches the inbox. However, I highly doubt this is doable. Please correct me if I'm wrong.
You can init a Git directory in an directory containing other files. After that you can add files to the repository and commit there.
Create a project with some code:
$ mkdir my_project
$ cd my_project
$ echo "foobar" > some_file
Then, while inside the project's folder, do an initial commit:
$ git init
$ git add some_file
$ git commit -m "Initial commit"
Then for using Bitbucket or such you add a remote
and push up:
$ git remote add some_name user@host:repo
$ git push some_name
You also might then want to configure tracking branches, etc. See git remote set-branches
and related commands for that.
I created my markup to insert as a string since it's less code and easier to read than working with the fancy dom stuff.
Then I made it innerHTML of a temporary element just so I could take the one and only child of that element and attach to the body.
var html = '<div>';
html += 'Hello div!';
html += '</div>';
var tempElement = document.createElement('div');
tempElement.innerHTML = html;
document.getElementsByTagName('body')[0].appendChild(tempElement.firstChild);
You can achieve this with MAVEN_OPTS, for example
MAVEN_OPTS=-Dorg.slf4j.simpleLogger.defaultLogLevel=warn mvn clean
Rather than putting the system property directly on the command line. (At least for maven 3.3.1.)
Consider using ~/.mavenrc
for setting MAVEN_OPTS
if you would like logging changed for your login across all maven invocations.
Here's a solution that:
Partial<...>
)OnlyData<...>
solution)The only drawback is that it looks more complicated at first.
// Define all fields here
interface PersonParams {
id: string
name?: string
coolCallback: () => string
}
// extend the params interface with an interface that has
// the same class name as the target class
// (if you omit the Params interface, you will have to redeclare
// all variables in the Person class)
interface Person extends PersonParams { }
// merge the Person interface with Person class (no need to repeat params)
// person will have all fields of PersonParams
// (yes, this is valid TS)
class Person {
constructor(params: PersonParams) {
// could also do Object.assign(this, params);
this.id = params.id;
this.name = params.name;
// intellisence will expect params
// to have `coolCallback` but not `sayHello`
this.coolCallback = params.coolCallback;
}
// compatible with functions
sayHello() {
console.log(`Hi ${this.name}!`);
}
}
// you can only export on another line (not `export default class...`)
export default Person;
Here is a special case that might be good enough:
[ (1.0/divStep)*x for x in range(start*divStep, stop*divStep)]
In your case this would be:
#for(float x = 0; x < 10; x += 0.5f) { /* ... */ } ==>
start = 0
stop = 10
divstep = 1/.5 = 2 #This needs to be int, thats why I said 'special case'
and so:

I found the OpenSSL answer given above didn't work for me, but the following did, working with a CRT file sourced from windows.
openssl x509 -inform DER -in yourdownloaded.crt -out outcert.pem -text
To answer your question. I would say it's fairly common for applications to replace spaces in values that will be used in URLs. The reason for this is ussually to avoid the more difficult to read percent (URI) encoding that occurs.
Check out this wikipedia article about Percent-encoding.
This post has already a very good answer by "Community wiki" and I also recommend to look at Rick Strahl's Web Blog, there are many good posts about WCF Rest like this.
I used both to get this kind of MyService-service... Then I can use the REST-interface from jQuery or SOAP from Java.
This is from my Web.Config:
<system.serviceModel>
<services>
<service name="MyService" behaviorConfiguration="MyServiceBehavior">
<endpoint name="rest" address="" binding="webHttpBinding" contract="MyService" behaviorConfiguration="restBehavior"/>
<endpoint name="mex" address="mex" binding="mexHttpBinding" contract="MyService"/>
<endpoint name="soap" address="soap" binding="basicHttpBinding" contract="MyService"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="restBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
And this is my service-class (.svc-codebehind, no interfaces required):
/// <summary> MyService documentation here ;) </summary>
[ServiceContract(Name = "MyService", Namespace = "http://myservice/", SessionMode = SessionMode.NotAllowed)]
//[ServiceKnownType(typeof (IList<MyDataContractTypes>))]
[ServiceBehavior(Name = "MyService", Namespace = "http://myservice/")]
public class MyService
{
[OperationContract(Name = "MyResource1")]
[WebGet(ResponseFormat = WebMessageFormat.Xml, UriTemplate = "MyXmlResource/{key}")]
public string MyResource1(string key)
{
return "Test: " + key;
}
[OperationContract(Name = "MyResource2")]
[WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource/{key}")]
public string MyResource2(string key)
{
return "Test: " + key;
}
}
Actually I use only Json or Xml but those both are here for a demo purpose. Those are GET-requests to get data. To insert data I would use method with attributes:
[OperationContract(Name = "MyResourceSave")]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource")]
public string MyResourceSave(string thing){
//...
Assuming that you already downloaded chromeDriver, this error is also occurs when already multiple chrome tabs are open.
If you close all tabs and run again, the error should clear up.
Here's a general procedure for producing a random number in a specified range:
int randInRange(int min, int max)
{
return min + (int) (rand() / (double) (RAND_MAX + 1) * (max - min + 1));
}
Depending on the PRNG algorithm being used, the %
operator may result in a very non-random sequence of numbers.
this question shows up pretty high on a Google search and worked for the most part! I did find that Salman Zaidi's answer was partially correct for iOS 7.
You need to make a modification to the "reverting" code. I found that the following for reverting worked perfectly:
textField.layer.cornerRadius = 0.0f;
textField.layer.masksToBounds = YES;
textField.layer.borderColor = [[UIColor blackColor] CGColor];
textField.layer.borderWidth = 0.0f;
I understand that this is most likely due to changes in iOS 7.
According to the W3C File API specification, the File constructor requires 2 (or 3) parameters.
So to create a empty file do:
var f = new File([""], "filename");
The third argument looks like:
var f = new File([""], "filename.txt", {type: "text/plain", lastModified: date})
It works in FireFox, Chrome and Opera, but not in Safari or IE/Edge.
for ($s=65; $s<=90; $s++) {
//echo chr($s);
$objPHPExcel->getActiveSheet()->getColumnDimension(chr($s))->setAutoSize(true);
}
In your form are you passing in any other attributes, via mass assignment that don't belong to your user model, or any of the nested models?
If so, I believe the ActiveRecord::UnknownAttributeError is triggered in this instance.
Otherwise, I think you can just create your own controller, by generating something like this:
# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
def new
super
end
def create
# add custom create logic here
end
def update
super
end
end
And then tell devise to use that controller instead of the default with:
# app/config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}
This can be achieved assigning weight
to every button added inside the container, very important to define horizontal orientation :
int buttons = 5;
RadioGroup rgp = (RadioGroup) findViewById(R.id.radio_group);
rgp.setOrientation(LinearLayout.HORIZONTAL);
for (int i = 1; i <= buttons; i++) {
RadioButton rbn = new RadioButton(this);
rbn.setId(1 + 1000);
rbn.setText("RadioButton" + i);
//Adding weight
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 1f);
rbn.setLayoutParams(params);
rgp.addView(rbn);
}
so we can get this in our device as a result:
even if we rotate our device the weight
defined in each button can distribuite the elemenents uniformally along the container:
There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple
To shorten it up a little:
geocoder = new google.maps.Geocoder();
function codeAddress() {
//In this case it gets the address from an element on the page, but obviously you could just pass it to the method instead
var address = document.getElementById( 'address' ).value;
geocoder.geocode( { 'address' : address }, function( results, status ) {
if( status == google.maps.GeocoderStatus.OK ) {
//In this case it creates a marker, but you can get the lat and lng from the location.LatLng
map.setCenter( results[0].geometry.location );
var marker = new google.maps.Marker( {
map : map,
position: results[0].geometry.location
} );
} else {
alert( 'Geocode was not successful for the following reason: ' + status );
}
} );
}
You can't resize an array in Java. You'd need to either:
Create a new array of the desired size, and copy the contents from the original array to the new array, using java.lang.System.arraycopy(...);
Use the java.util.ArrayList<T>
class, which does this for you when you need to make the array bigger. It nicely encapsulates what you describe in your question.
Use java.util.Arrays.copyOf(...)
methods which returns a bigger array, with the contents of the original array.
I know this is old but here's a one liner list comprehension:
data = ['word1, 23, 12','word2, 10, 19','word3, 11, 15']
[[int(item) if item.isdigit() else item for item in items.split(', ')] for items in data]
or
[int(item) if item.isdigit() else item for items in data for item in items.split(', ')]

There are many options how to write a regex pattern for that
^(?:(?!0)\d{1,2}|100)$
^(?:[1-9]\d?|100)$
^(?!0)(?=100$|..$|.$)\d+$
The following creates a generic function, taking an array of any size and of any type by reference:
template<typename T, std::size_t S>
void my_func(T (&arr)[S]) {
// do stuff
}
As you can see, the import command did work but is showing errors because it tried to locate the resources in vendor.css and couldn't find them
You should also upload your project structure and ensure that there aren't any path issues. Also, you could include the css file in the index.html or the Component template and webpack loader would extract it when built
The packages you installed introduced dependencies to version 5.2.3.0 dll's as user Bracher showed above. Microsoft.AspNet.WebApi.Cors is an example package. The path I take is to update the MVC project proir to any package installs:
Install-Package Microsoft.AspNet.Mvc -Version 5.2.3
You can use font awesome utf cheatsheet

I think that this is valid :)
In addition to the above, for others having the following issue:
"If the props value is not required and thus not always returned, the passed data would return undefined
(instead of empty)". Which could mess <select>
default value, I solved it by checking if the value is set in beforeMount()
(and set it if not) as follows:
JS:
export default {
name: 'user_register',
data: () => ({
oldDobMonthMutated: this.oldDobMonth,
}),
props: [
'oldDobMonth',
'dobMonths', //Used for the select loop
],
beforeMount() {
if (!this.oldDobMonth) {
this.oldDobMonthMutated = '';
} else {
this.oldDobMonthMutated = this.oldDobMonth
}
}
}
Html:
<select v-model="oldDobMonthMutated" id="dob_months" name="dob_month">
<option selected="selected" disabled="disabled" hidden="hidden" value="">
Select Month
</option>
<option v-for="dobMonth in dobMonths"
:key="dobMonth.dob_month_slug"
:value="dobMonth.dob_month_slug">
{{ dobMonth.dob_month_name }}
</option>
</select>
Check your JAVA_HOME path. As systems looks for a java.policy file which is located in JAVA_HOME/jre/lib/security
. Your JAVA_HOME should always be ../JAVA/JDK
.
Another option is to put all of the fields that you want on a single line within a single form-group
.
<form class="form-horizontal">
<div class="form-group">
<label for="name" class="col-xs-2 control-label">Name</label>
<div class="col-xs-10">
<input type="text" class="form-control col-sm-10" name="name" placeholder="name"/>
</div>
</div>
<div class="form-group">
<label for="birthday" class="col-xs-3 col-sm-2 control-label">Birthday</label>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder="year"/>
</div>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder="month"/>
</div>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder="day"/>
</div>
</div>
</form>
I had the same issue and came up with the following that uses underscore's _.filter method. Once I discovered that removeClass takes a function and provides you with a list of classnames, it was easy to turn that into an array and filter out the classname to return back to the removeClass method.
// Wildcard removeClass on 'color-*'
$('[class^="color-"]').removeClass (function (index, classes) {
var
classesArray = classes.split(' '),
removeClass = _.filter(classesArray, function(className){ return className.indexOf('color-') === 0; }).toString();
return removeClass;
});
Use the following lines of codes and you will find the solution...
pictureBox1.ImageLocation = @"C:\Users\Desktop\mypicture.jpg";
pictureBox1.SizeMode =PictureBoxSizeMode.StretchImage;
I think using NOW()
function is incorrect for getting time difference. Because by NOW()
function every time your are calculating the past 24 hours.
You must use CURDATE()
instead.
function your_function($time, $your_date) {
if ($time == 'today') {
$timeSQL = ' Date($your_date)= CURDATE()';
}
if ($time == 'week') {
$timeSQL = ' YEARWEEK($your_date)= YEARWEEK(CURDATE())';
}
if ($time == 'month') {
$timeSQL = ' Year($your_date)=Year(CURDATE()) AND Month(`your_date`)= Month(CURDATE())';
}
$Sql = "SELECT * FROM jokes WHERE ".$timeSQL
return $Result = $this->db->query($Sql)->result_array();
}
Your rows
object holds an Item
attribute where you can find the values for each of your columns. You can not expect the columns to concatenate themselves when you do a .ToString()
on the row.
You should access each column from the row separately, use a for
or a foreach
to walk the array of columns.
Here, take a look at the class:
http://msdn.microsoft.com/en-us/library/system.data.datarow.aspx
same from above example - if you are just looking for json (not an array of object) just use
function getJsonDetails() {
item = {}
item ["token1"] = token1val;
item ["token2"] = token1val;
return item;
}
console.log(JSON.stringify(getJsonDetails()))
this output ll print as (a valid json)
{
"token1":"samplevalue1",
"token2":"samplevalue2"
}
Not sure if Access supports it, but in most engines (including SQL Server
) this is called a correlated subquery and works fine:
SELECT TypesAndBread.Type, TypesAndBread.TBName,
(
SELECT Count(Sandwiches.[SandwichID]) As SandwichCount
FROM Sandwiches
WHERE (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
) As SandwichCount
FROM TypesAndBread
This can be made more efficient by indexing Type
and Bread
and distributing the subqueries over the UNION
:
SELECT [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
(
SELECT COUNT(*) As SandwichCount
FROM Sandwiches
WHERE Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
)
FROM [Sandwiches Types]
UNION ALL
SELECT [Breads].[Bread] As TBName, "Bread" As Type,
(
SELECT COUNT(*) As SandwichCount
FROM Sandwiches
WHERE Sandwiches.Bread = [Breads].[Bread]
)
FROM [Breads]
To fetch even records
select *

where mod(r,2)=1;
Be sure that android:debuggable="true"
is set in the application

In my case, it happened when one table is InnoB and other is MyISAM. Changing engine of one table, through MySQL Workbench, solves for me.

It works in the edu version for me. It was not necessary for me to specify a -s option in the interpreter options.
Adding "/usr/bin/git" >> Path to Git executable, didn't work for me. Then I deleted the contents of $JENKINS_HOME/fingerprints and restarted Jenkins. The problem goes away.
I Suggest you to use both Input Submit / Button instead of anchor and put this line of code onClick="javascript:location.href = 'http://stackoverflow.com';"
in that Input Submit / Button which you want to work as link.
Submit Example
<input type="submit" value="Submit" onClick="javascript:location.href = 'some_url';" />
Button Example
<button type="button" onClick="javascript:location.href = 'some_url';" />Submit</button>
There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.
If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.
Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.
Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.
Although all the answers given are correct, in fact they do not completely answer the question which was about using the [] construct and more generally filling the array with objects.
A more relevant answer can be found in how to build arrays of objects in PHP without specifying an index number? which clearly shows how to solve the problem.
Some facts about POSIX that are not so bright.
POSIX is also the system call interface or API, and it is nearly 30 years old.
It was designed for serialized data access to local storage, using single computers with single CPUs.
Security was not a major concern in POSIX by design, leading to numerous race condition attacks over the years and forcing programmers to work around these limitations.
Serious bugs are still being discovered, bugs that could have been averted with a more secure POSIX API design.
POSIX expects users to issue one synchronous call at a time and wait for its results before issuing the next. Today's programmers expect to issue many asynchronous requests at a time to improve overall throughput.
This synchronous API is particularly bad for accessing remote and cloud objects, where high latency matters.
Easy way with a touch of javascript
$("#myButton").click(function(event) {
var cont = confirm('Continue?');
if(cont) {
// do stuff here if OK was clicked
return true;
}
// If cancel was clicked button execution will be halted.
event.preventDefault();
}
Try the following:
adb kill-server
adb start-server
Try putting your code inside a main function in testMain.py
import parallelTestModule
if __name__ == '__main__':
extractor = parallelTestModule.ParallelExtractor()
extractor.runInParallel(numProcesses=2, numThreads=4)
See the docs:
"For an explanation of why (on Windows) the if __name__ == '__main__'
part is necessary, see Programming guidelines."
which say
"Make sure that the main module can be safely imported by a new Python interpreter without causing unintended side effects (such a starting a new process)."
... by using if __name__ == '__main__'
To get the root view defined in your xml file, without action bar, you can use this:
View root = ((ViewGroup) findViewById(android.R.id.content)).getChildAt(0);
So, to change color to white:
root.setBackgroundResource(Color.WHITE);
It is possible the other branch you try to pull from is out of synch; so before adding and removing remote try to (if you are trying to pull from master)
git pull origin master
for me that simple call solved those error messages:
You should introduce a cast inside the click
event handler
MouseEventArgs me = (MouseEventArgs) e;
If you're doing this in Drupal and use the Form API to change the #type from text to 'hidden' in hook_form_alter (for example), be advised that the output HTML will have different (or omitted) DIV wrappers, IDs and class names.
In Eclipse,
Go to your class,
Right click->source->Generate toString()
;
It will override the toString()
method and will print the object of that class.
Yes, Json.Net is what you need. You basically want to deserialize a Json string into an array of objects
.
See their examples:
string myJsonString = @"{
"Name": "Apple",
"Expiry": "\/Date(1230375600000+1300)\/",
"Price": 3.99,
"Sizes": [
"Small",
"Medium",
"Large"
]
}";
// Deserializes the string into a Product object
Product myProduct = JsonConvert.DeserializeObject<Product>(myJsonString);
In rails, I've previously done something like this:
class ApplicationController < ActionController::Base
# ...
private def bool_from(value)
!!ActiveRecord::Type::Boolean.new.type_cast_from_database(value)
end
helper_method :bool_from
# ...
end
Which is nice if you're trying to match your boolean strings comparisons in the same manner as rails would for your database.
As per this the default is 2 MB for your <Connector>
.
maxPostSize = The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).
Edit Tomcat's server.xml. In the <Connector>
element, add an attribute maxPostSize
and set a larger value (in bytes) to increase the limit.
Having said that, if this is the issue, you should have got an exception on the lines of
Post data too big
in tomcat
Java has a assert
statement, the JVM disables assertion validation by default. They must be explicitly enabled using command line argument -enableassertions
(or its shorthand -ea
),
while JavaScript supports console.assert()
, it's just a logging method and won't interrupt current procedure if assertion failed.
To bring things together and satisfy various needs, here is a tiny js assertion lib.
globalThis.assert = (()=> {
class AssertionError extends Error {
constructor(message) {
super(message);
this.name = 'AssertionError';
}
}
let config = {
async: true,
silent: false
};
function assert(condition, message = undefined) {
if (!condition) {
if (config.silent) {
//NOOP
} else if (config.async) {
console.assert(condition, message || 'assert');
} else {
throw new AssertionError(message || 'assertion failed');
}
}
}
assert.config = config;
return assert;
})();
/* global assert */
Object.assign(assert.config, {
// silent: true, // to disable assertion validation
async: false, // to validate assertion synchronously (will interrupt if assertion failed, like Java's)
});
let items = [
{id: 1},
{id: 2},
{id: 3}
];
function deleteItem(item) {
let index = items.findIndex((e)=> e.id === item.id);
assert(index > -1, `index should be >=0, the item(id=${item.id}) to be deleted doesn't exist, or was already deleted`);
items.splice(index, 1);
}
console.log('begin');
deleteItem({id: 1});
deleteItem({id: 1});
console.log('end');

Just finished understanding Peek and Keep and had same confusion initially. The confusion arises becauses TempData behaves differently under different condition. You can watch this video which explains the Keep and Peek with demonstration https://www.facebook.com/video.php?v=689393794478113
Tempdata helps to preserve values for a single request and CAN ALSO preserve values for the next request depending on 4 conditions”.
If we understand these 4 points you would see more clarity.Below is a diagram with all 4 conditions, read the third and fourth point which talks about Peek and Keep.
Condition 1 (Not read):- If you set a “TempData” inside your action and if you do not read it in your view then “TempData” will be persisted for the next request.
Condition 2 ( Normal Read) :- If you read the “TempData” normally like the below code it will not persist for the next request.
string str = TempData["MyData"];
Even if you are displaying it’s a normal read like the code below.
@TempData["MyData"];
Condition 3 (Read and Keep) :- If you read the “TempData” and call the “Keep” method it will be persisted.
@TempData["MyData"];
TempData.Keep("MyData");
Condition 4 ( Peek and Read) :- If you read “TempData” by using the “Peek” method it will persist for the next request.
string str = TempData.Peek("Td").ToString();
Reference :- http://www.codeproject.com/Articles/818493/MVC-Tempdata-Peek-and-Keep-confusion

Here is a solution for a recently opened question marked as a duplicate of this question. The <img>
tag was exceeding the max-height of the parent <div>
.
Broken: Fiddle
Working: Fiddle
In this case, adding display:flex
to the 2 parent <div>
tags was the answer
Use the rowid
pseudocolumn.
DELETE FROM your_table
WHERE rowid not in
(SELECT MIN(rowid)
FROM your_table
GROUP BY column1, column2, column3);
Where column1
, column2
, and column3
make up the identifying key for each record. You might list all your columns.
You can also use "smart-ip" service:
$.getJSON("http://smart-ip.net/geoip-json?callback=?",
function (data) {
alert(data.countryName);
alert(data.city);
}
);
You can do the same with build.gradle
sonarqube {
properties {
property "sonar.exclusions", "**/src/java/test/**/*.java"
}
}
And if you want to exclude more files/directories then:
sonarqube {
properties {
property "sonar.exclusions", "**/src/java/test/**/*.java, **/src/java/main/**/*.java"
}
}
You can use like this
public static string ReadFileAndFetchStringInSingleLine(string file)
{
StringBuilder sb;
try
{
sb = new StringBuilder();
using (FileStream fs = File.Open(file, FileMode.Open))
{
using (BufferedStream bs = new BufferedStream(fs))
{
using (StreamReader sr = new StreamReader(bs))
{
string str;
while ((str = sr.ReadLine()) != null)
{
sb.Append(str);
}
}
}
}
return sb.ToString();
}
catch (Exception ex)
{
return "";
}
}
Hope this will help you.
The very same. A C string is nothing but an array of characters, so a pointer to a string is a pointer to an array of characters. And a pointer to an array is the very same as a pointer to its first element.
Yes, you must open php.ini
and remove the semicolon to:
;extension=php_openssl.dll
If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext
) and add this to php.ini
in the "Dynamic Extensions" section:
extension=php_openssl.dll
Things have changed for PHP > 7. This is what i had to do for PHP 7.2.
Step: 1: Uncomment extension=openssl
Step: 2: Uncomment extension_dir = "ext"
Step: 3: Restart xampp.
Done.
Explanation: ( From php.ini )
If you wish to have an extension loaded automatically, use the following syntax:
extension=modulename
Note : The syntax used in previous PHP versions (extension=<ext>.so
and extension='php_<ext>.dll
) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>
) syntax.
Special Note: Be sure to appropriately set the extension_dir
directive.
You are pretty confused my friend. There are no LOOPS in SQL, only in PL/SQL. Here's a few examples based on existing Oracle table - copy/paste to see results:
-- Numeric FOR loop --
set serveroutput on -->> do not use in TOAD --
DECLARE
k NUMBER:= 0;
BEGIN
FOR i IN 1..10 LOOP
k:= k+1;
dbms_output.put_line(i||' '||k);
END LOOP;
END;
/
-- Cursor FOR loop --
set serveroutput on
DECLARE
CURSOR c1 IS SELECT * FROM scott.emp;
i NUMBER:= 0;
BEGIN
FOR e_rec IN c1 LOOP
i:= i+1;
dbms_output.put_line(i||chr(9)||e_rec.empno||chr(9)||e_rec.ename);
END LOOP;
END;
/
-- SQL example to generate 10 rows --
SELECT 1 + LEVEL-1 idx
FROM dual
CONNECT BY LEVEL <= 10

You should put android:inputType="textCapCharacters"
with Edittext in xml file.
There is a huge difference.
As most of the answers have already pointed out the theory, I would like to point out an easy example:
int x = 1;
//would print 1 as first statement will x = x and then x will increase
int x = x++;
System.out.println(x);
Now let's see ++x
:
int x = 1;
//would print 2 as first statement will increment x and then x will be stored
int x = ++x;
System.out.println(x);
Another option is to search the XML as a string by converting it to a string and then using LIKE. However as a computed column can't be part of a WHERE clause you need to wrap it in another SELECT like this:
SELECT * FROM
(SELECT *, CONVERT(varchar(MAX), [COLUMNA]) as [XMLDataString] FROM TABLE) x
WHERE [XMLDataString] like '%Test%'
Yes by using spring-boot with hibernate configuration files we can persist the data to the database. keep hibernating .cfg.xml in your src/main/resources folder for reading the configurations related to database.
List<Class1> list = new List<Class1>();
int index = list.FindIndex(item => item.Number == textBox6.Text);
Class1 newItem = new Class1();
newItem.Prob1 = "SomeValue";
list[index] = newItem;
If you are generally doing updates I would ..
If you are generally doing inserts I would
This way you avoid the select and you are transactionally sound on Sqlite.

Probably the simplest way to do it is to create a delegate and then BeginInvoke
, followed by a wait at some time in the future, and an EndInvoke
.
public bool Foo(){
Thread.Sleep(100000); // Do work
return true;
}
public SomeMethod()
{
var fooCaller = new Func<bool>(Foo);
// Call the method asynchronously
var asyncResult = fooCaller.BeginInvoke(null, null);
// Potentially do other work while the asynchronous method is executing.
// Finally, wait for result
asyncResult.AsyncWaitHandle.WaitOne();
bool fooResult = fooCaller.EndInvoke(asyncResult);
Console.WriteLine("Foo returned {0}", fooResult);
}
If you are using JAX-WS on JDK6, use the following properties:
com.sun.xml.internal.ws.connect.timeout

This makes it so if before there was a scrollbar then it makes it so the scrollbar has a display of none so you can't see it anymore. You can replace html to body or a class or ID. Hope it works for you :)
html::-webkit-scrollbar {
display: none;
}
Every answer seems to suggest that you need to use secure hashes to do the job but all of these are tuned to be slow to force a bruteforce attacker to have lots of computing power and depending on your needs this may not be the best solution.
There are algorithms specifically designed to hash files as fast as possible to check integrity and comparison (murmur
, XXhash
...). Obviously these are not designed for security as they don't meet the requirements of a secure hash algorithm (i.e. randomness) but have low collision rates for large messages. This features make them ideal if you are not looking for security but speed.
Examples of this algorithms and comparison can be found in this excellent answer: Which hashing algorithm is best for uniqueness and speed?.
As an example, we at our Q&A site use murmur3
to hash the images uploaded by the users so we only store them once even if users upload the same image in several answers.
use enumerate:
>>> l = ['a', 'b', 'c', 'd']
>>> for index, val in enumerate(l):
... print "%d: %s" % (index, val)
...
0: a
1: b
2: c
3: d

Selector Context By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function. For example, to do a search within an event handler, the search can be restricted like so:
$( "div.foo" ).click(function() {
$( "span", this ).addClass( "bar" );
});
When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.
So for your example I would suggest something like:
$("div", ".container").each(function(){
//do whatever
});
It is also possible to symlink the datadir. At least in macOS, dev environment.
(homebrew) e. g.
# make sure you're not overwriting anything important, backup existing data
mv /usr/local/var/mysql [your preferred data directory]
ln -s [your preferred data directory] /usr/local/var/mysql
Restart mysql.
I commonly like to use a slight variant on the standard for loop. I often use this to run a command on a series of remote hosts. I take advantage of bash's brace expansion to create for loops that allow me to create non-numerical for-loops.
Example:
I want to run the uptime command on frontend hosts 1-5 and backend hosts 1-3:
% for host in {frontend{1..5},backend{1..3}}.mycompany.com
do ssh $host "echo -n $host; uptime"
done
I typically run this as a single-line command with semicolons on the ends of the lines instead of the more readable version above. The key usage consideration are that braces allow you to specify multiple values to be inserted into a string (e.g. pre{foo,bar}post results in prefoopost, prebarpost) and allow counting/sequences by using the double periods (you can use a..z etc.). However, the double period syntax is a new feature of bash 3.0; earlier versions will not support this.
If Subversion is already installed ,there's no need to reinstall it with the command line client tools.
Simply Goto
Start(Rightclick) ->App and Feature ->TortoiseSvn->Modify->Install command line client tools.
Yet another method is using the LOOP instruction:
mov cx, 3
myloop:
; Your loop content
loop myloop
The loop instruction automatically decrements cx, and only jumps if cx != 0. There are also LOOPE, and LOOPNE variants, if you want to do some additional check for your loop to break out early.
If you want to modify cx during your loop, make sure to push it onto the stack before the loop content, and pop it off after:
mov cx, 3
myloop:
push cx
; Your loop content
pop cx
loop myloop
It sounds like more of an architectual issue, and any timeout/disconnect you can do would be more or less a band-aid. This has to be solved on SQL server side, by the way of read-only replica, transaction log shipping (to give you a read-only server to connect to), replication and such. Basically you give the DMZ sql server that heavy read can go to without killing stuff. This is very common. A well-designed SQL system won't be taken down by DDoS - that'd be like a car that dies if you step on the gas.
That said, if you are at the liberty to change the code, you could guesstimate if the query is too heavy and you could either reject or return only X rows in your stored procedure. If you are mated to some reporting tool and such and can't control the SELECT it generates, you could point it to a view and then do the safety valve in the view.
Also, if up-to-the-minute freshness isn't critical and you could compromise on that, like monthly sales data, then compiling a physical table of complex joins by job to avoid complex joins might do the trick - that way everything would be sub-second per query.
It entirely depends on what you are doing, but there is always a solution. Sometimes it takes extra coding to optimize it, sometimes it takes extra money to get you the secondary read-only DB, sometimes it needs time and attention in index tuning.
So it entirely depends, but I'd start with "what can I compromise? what can I change?" and go from there.

You can install ANT through macports or homebrew.
But if you want to do without 3rd party package managers, the problem can simply be fixed by downloading the binary release from the apache ANT web site and adding the binary to your system PATH.
For example, on Mountain Lion, in ~/.bash_profile
and ~/.bashrc
my path was setup like this:
export ANT_HOME="/usr/share/ant"
export PATH=$PATH:$ANT_HOME/bin
So after uncompressing apache-ant-1.9.2-bin.tar.bz2
I moved the resulting directory to /usr/share/
and renamed it ant
.
Simple as that, the issue is fixed.
Note Don't forget to sudo chown -R root:wheel /usr/share/ant
Using REQUIRES_NEW
is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED
- it will create a new transaction.
That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional
, it will create a new transaction.
So, with that in mind, if using REQUIRES_NEW
makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.
On rollback - using REQUIRES_NEW
will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations.
Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.
The difference seems to be the amount of control you need over the animation.
The CATransition
approach gives you more control and therefore more things to set up, eg. the timing function. Being an object, you can store it for later, refactor to point all your animations at it to reduce duplicated code, etc.
The UIView
class methods are convenience methods for common animations, but are more limited than CATransition
. For example, there are only four possible transition types (flip left, flip right, curl up, curl down). If you wanted to do a fade in, you'd have to either dig down to CATransition's
fade transition, or set up an explicit animation of your UIView
's alpha.
Note that CATransition
on Mac OS X will let you specify an arbitrary CoreImage
filter to use as a transition, but as it stands now you can't do this on the iPhone, which lacks CoreImage
.
What about this?
return ((num + "").charAt(0) == '-');
You can just add style="min-height:100vh" to your page content conteiner and place footer in another conteiner
This approach will work on all API level device.
Use Base Activity for attachBaseContext to set the locale language and extend this activity for all activities
open class BaseAppCompactActivity() : AppCompatActivity() {
override fun attachBaseContext(newBase: Context) {
super.attachBaseContext(LocaleHelper.onAttach(newBase))
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
}
}
Use Application attachBaseContext and onConfigurationChanged
to set the locale language
public class MyApplication extends Application {
private static MyApplication application;
@Override
public void onCreate() {
super.onCreate();
}
public static MyApplication getApplication() {
return application;
}
/**
* overide to change local sothat language can be chnaged from android device nogaut and above
*/
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(LocaleHelper.INSTANCE.onAttach(base));
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
setLanguageFromNewConfig(newConfig);
super.onConfigurationChanged(newConfig);
}
/*** also handle chnage language if device language chnaged **/
private void setLanguageFromNewConfig(Configuration newConfig){
Prefs.putSaveLocaleLanguage(this, selectedLocaleLanguage );
LocaleHelper.INSTANCE.onAttach(this);
}
Use Locale Helper for handling language changes, this approach work on all device
object LocaleHelper {
private var defaultLanguage :String = KycUtility.KYC_LANGUAGE.ENGLISH.languageCode
fun onAttach(context: Context, defaultLanguage: String): Context {
return setLocale(context, defaultLanguage)
}
fun setLocale(context: Context, language: String): Context {
return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
updateResources(context, language)
} else updateResourcesLegacy(context, language)
}
@TargetApi(Build.VERSION_CODES.N)
private fun updateResources(context: Context, language: String): Context {
val locale = Locale(language)
Locale.setDefault(locale)
val configuration = context.getResources().getConfiguration()
configuration.setLocale(locale)
configuration.setLayoutDirection(locale)
return context.createConfigurationContext(configuration)
}
private fun updateResourcesLegacy(context: Context, language: String): Context {
val locale = Locale(language)
Locale.setDefault(locale)
val resources = context.getResources()
val configuration = resources.getConfiguration()
configuration.locale = locale

I believe there is a maximum number of concurrent http requests that browsers will make to the same domain, which is in the order of 4-8 requests depending on the user's settings and browser.
You could set up your requests to go to different domains, which may or may not be feasible. The Yahoo guys did a lot of research in this area, which you can read about (here). Remember that every new domain you add also requires a DNS lookup. The YSlow guys recommend between 2 and 4 domains to achieve a good compromise between parallel requests and DNS lookups, although this is focusing on the page's loading time, not subsequent AJAX requests.
Can I ask why you want to make so many requests? There is good reasons for the browsers limiting the number of requests to the same domain. You will be better off bundling requests if possible.
You can also try using apply
with get
method of dictionary
, seems to be little faster than replace
:
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)
Testing with timeit
:
%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)
Result:
The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop
Using apply
:
%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)
Result:
The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop
Note: apply
with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.
Instead of using a dot, like: 1.2, try to input like this: 1,2.
You need to verify that the SQL Server service is running. You can do this by going to Start > Control Panel > Administrative Tools > Services
, and checking that the service SQL Server (SQLEXPRESS
) is running. If not, start it.
While you're in the services applet, also make sure that the service SQL Browser is started. If not, start it.
You need to make sure that SQL Server is allowed to use TCP/IP or named pipes. You can turn these on by opening the SQL Server Configuration Manager in Start > Programs > Microsoft SQL Server 2012 > Configuration Tools
(or SQL Server Configuration Manager
), and make sure that TCP/IP and Named Pipes are enabled. If you don't find the SQL Server Configuration Manager in the Start Menu you can launch the MMC snap-in manually. Check SQL Server Configuration Manager for the path to the snap-in according to your version.
Verify your SQL Server connection authentication mode matches your connection string:
If you're connecting using a username and password, you need to configure SQL Server to accept "SQL Server Authentication Mode":
-- YOU MUST RESTART YOUR SQL SERVER AFTER RUNNING THIS!
USE [master]
GO
DECLARE @SqlServerAndWindowsAuthenticationMode INT = 2;
EXEC xp_instance_regwrite
N'HKEY_LOCAL_MACHINE',
N'Software\Microsoft\MSSQLServer\MSSQLServer',
N'LoginMode',
REG_DWORD,
@SqlServerAndWindowsAuthenticationMode;
GO
otherwise, run Start -> Run -> Services.msc
If so, is it running?
If it's not running then
It sounds like you didn't get everything installed. Launch the install file and chose the option "New installation or add features to an existing installation". From there you should be able to make sure the database engine service gets installed.

1) check if service declaration in manifest is nested in application tag
<application>
<service android:name="" />

2) check if your service.java

You can use these commands: git remote update, git fetch, git checkout -b branch_nameA origin:branch_nameB
I think maybe it's because of your local branch can not track remote branch
It's because you have included a leading /
in your file path. The /
makes it start at the top of your filesystem. Note: filesystem path, not Web site path (you're not accessing it over HTTP). You can use a relative path with include_once
(one that doesn't start with a leading /
).
You can change it to this:
include_once 'headerSite.php';
That will look first in the same directory as the file that's including it (i.e. C:\xampp\htdocs\PoliticalForum\
in your example.
Using a char when the variable is a string won't work. Using
switch (hello.charAt(0))
you will extract the first character of the hello variable instead of trying to use the variable as it is, in string form. You also need to get rid of your space inside

I was having this issue and nothing worked. I ran xcode-select --install
and also installed /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
.
BACKGROUND
Since I was having issues with App Store on a new laptop, I was forced to download the Xcode Beta installer from the Apple website to install Xcode outside App Store. So I only had Xcode Beta installed.
SOLUTION
This, (I think), was making clang
to not find the SDKROOT
directory /Applications/Xcode.app/....
, because there is no Beta
in the path, or maybe Xcode Beta simply doesn't install it (I don't know).
To fix the issue, I had to remove Xcode Beta and resolve the App Store issue to install the release version.
tldr;
If you have Xcode Beta, try cleaning up everything and installing the release version before trying out the solutions that are working for other people.
