If you use MVC, tables, it works like this:
<td>@(((DateTime)detalle.fec).ToString("dd'/'MM'/'yyyy"))</td>
You can use this to send sms to any number:
public void sendsms(View view) {
String phoneNumber = "+880xxxxxxxxxx";
String message = "Welcome to sms";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + phoneNumber));
intent.putExtra("sms_body", message);
startActivity(intent);
}
WITH SensorTimes As (
SELECT sensorID, MAX(timestamp) "LastReading"
FROM sensorTable
GROUP BY sensorID
)
SELECT s.sensorID,s.timestamp,s.sensorField1,s.sensorField2
FROM sensorTable s
INNER JOIN SensorTimes t on s.sensorID = t.sensorID and s.timestamp = t.LastReading
There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.
Similarity::Similarity()
or Similarity::~Similarity()
are just missing and you have defined the others incorrectly,
void Similarity::readData(Scanner& inStream){
}
not
void readData(Scanner& inStream){
}
etc. etc.
The second one is a function called readData, only the first is the readData method of the Similarity class.
To be clear about this, in Similarity.h
void readData(Scanner& inStream);
but in Similarity.cpp
void Similarity::readData(Scanner& inStream){
}
Another solution might look like this,
char arr[] = "mom";
std::cout << "hi " << std::string(arr);
which avoids using an extra variable.
You can use like this for check password contain at-least 1 Uppercase, 1 Lowercase, 1 Numeric and 1 special character :
$this->validate($request, [
'name' => 'required|min:3|max:50',
'email' => 'email',
'password' => 'required|confirmed|min:6|regex:/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{6,}$/']);
It can be fixed by changing your theme in styles.xml from Theme.AppCompat.Light.DarkActionBar to Base.Theme.AppCompat.Light.DarkActionBar
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
to
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
and clean the project. It will surely help.
I had this same problem installing SQL Server 2014. Turns out it was due to a Windows Phone toolkit that I had installed back in 2010. If you run into this, make sure you uninstall any Windows phone stuff that isn't current.
I figured it out by looking at the log, which can be found by clicking "Detailed Report," which opens an HTML file. The file path is conveniently displayed within the HTML page. Open the directory that the file is in and look for "Detail.txt." Then search for the word "fail."
In my case there was a line showing WP_[something] as "Installed." I searched for the WP_ item and came across some blog posts about trouble uninstalling Windows Phone toolkits.
When I attempted to uninstall the windows phone I ran into more trouble. The uninstaller wanted to install three packages instead of uninstalling the toolkit. Eventually found this blog post: http://blogs.msdn.com/b/astebner/archive/2010/07/12/10037442.aspx linking to this XNA cleanup tool: http://blogs.msdn.com/b/astebner/archive/2009/04/10/9544320.aspx.
I ran the cleanup tool and finally SQL Server installer passed the check and allowed me to install. Hope this helps someone.
You need to convert the string to date using the to_date()
function
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');
This will work only if OrderDate
is stored in Date format
. If it is Varchar
you should apply to_date()
func on that column also like
SELECT * FROM OrderArchive
WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');
As of Jackson 1.6, you can use:
JsonNode node = mapper.valueToTree(map);
or
JsonNode node = mapper.convertValue(object, JsonNode.class);

Javascript is single-threaded, so by nature there should not be a sleep function because sleeping will block the thread. setTimeout
is a way to get around this by posting an event to the queue to be executed later without blocking the thread. But if you want a true sleep function, you can write something like this:
function sleep(miliseconds) {
var currentTime = new Date().getTime();
while (currentTime + miliseconds >= new Date().getTime()) {
}
}
Note: The above code is NOT recommended.

For small tables DELETE
is often faster and needs less aggressive locking (for heavy concurrent load):
DELETE FROM tbl;
With no WHERE
condition.
For medium or bigger tables, go with TRUNCATE tbl
, like @Greg posted.
You could use a :
@RequestParam(value="somvalue",required=false)
for optional params rather than a pathVariable
Word of warning: if you put config files in your WEB-INF/classes
folder, and your IDE, say Eclipse, does a clean/rebuild, it will nuke your conf files unless they were in the Java source directory. BalusC's great answer alludes to that in option 1 but I wanted to add emphasis.
I learned the hard way that if you "copy" a web project in Eclipse, it does a clean/rebuild from any source folders. In my case I had added a "linked source dir" from our POJO java library, it would compile to the WEB-INF/classes
folder. Doing a clean/rebuild in that project (not the web app project) caused the same problem.
I thought about putting my confs in the POJO src folder, but these confs are all for 3rd party libs (like Quartz or URLRewrite) that are in the WEB-INF/lib
folder, so that didn't make sense. I plan to test putting it in the web projects "src" folder when i get around to it, but that folder is currently empty and having conf files in it seems inelegant.
So I vote for putting conf files in WEB-INF/commonConfFolder/filename.properties
, next to the classes folder, which is Balus option 2.

A segementation fault is an internal error in php (or, less likely, apache). Oftentimes, the segmentation fault is caused by one of the newer and lesser-tested php modules such as imagemagick or subversion.
Try disabling all non-essential modules (in php.ini
), and then re-enabling them one-by-one until the error occurs. You may also want to update php and apache.
If that doesn't help, you should report a php bug.
The numpy and scipy libraries include the composite trapezoidal (numpy.trapz) and Simpson's (scipy.integrate.simps) rules.
Here's a simple example. In both trapz
and simps
, the argument dx=5
indicates that the spacing of the data along the x axis is 5 units.
from __future__ import print_function
import numpy as np
from scipy.integrate import simps
from numpy import trapz
# The y values. A numpy array is used here,
# but a python list could also be used.
y = np.array([5, 20, 4, 18, 19, 18, 7, 4])
# Compute the area using the composite trapezoidal rule.
area = trapz(y, dx=5)
print("area =", area)
# Compute the area using the composite Simpson's rule.
area = simps(y, dx=5)
print("area =", area)
Output:
area = 452.5
area = 460.0

ClassFinder is a program that's designed to solve this problem. It allows you to search recursively through directories and jar files to find all instances of a class matching a pattern. It is written in Java, not python. It has a nice GUI which makes it easy to use. And it runs fast. This release is precompiled in a runnable jar so you don't have to build it from source.
Download it here: ClassFinder 1.0

For printing log use this function, this will create log file in log
folder. Create log folder if its not exists .
logger("Your msg in log ", "Filename you want ", "Data to be log string or array or object");
function logger($logMsg="logger", $filename="logger", $logData=""){
$log = date("j.n.Y h:i:s")." || $logMsg : ".print_r($logData,1).PHP_EOL .
"-------------------------".PHP_EOL;
file_put_contents('./log/'.$filename.date("j.n.Y").'.log', $log, FILE_APPEND);
}
This is how I did it ... it's not as convenient perhaps as having an 'optional argument' against your defined parameter, but it gets the job done:
public void postUserMessage(String s,boolean wipeClean)
{
if(wipeClean)
{
userInformation.setText(s + "\n");
}
else
{
postUserMessage(s);
}
}
public void postUserMessage(String s)
{
userInformation.appendText(s + "\n");
}
Notice I can invoke the same method name with either just a string or I can invoke it with a string and a boolean value. In this case, setting wipeClean to true will replace all of the text in my TextArea with the provided string. Setting wipeClean to false or leaving it out all together simply appends the provided text to the TextArea.
Also notice I am not repeating code in the two methods, I am merely adding the functionality of being able to reset the TextArea by creating a new method with the same name only with the added boolean.
I actually think this is a little cleaner than if Java provided an 'optional argument' for our parameters since we would need to then code for default values etc. In this example, I don't need to worry about any of that. Yes, I have added yet another method to my class, but it's easier to read in the long run in my humble opinion.
I fixed the problem by defining the following attribute in <activity>
of AndroidManifest.xml
android:windowSoftInputMode="adjustResize"
You just need to do the code below. The first [0] is to access the HTML element and second [0] is to access the first file of the file upload (I included a validation in case that there is no file):
var filename = $('input[type=file]')[0].files.length ? ('input[type=file]')[0].files[0].name : "";
ArrayList<Integer>[] graph = new ArrayList[numCourses]
It works.

The accepted answer has some gotchas. For example:
>>> a = [{}] * 3
>>> a
[{}, {}, {}]
>>> a[0]['hello'] = 5
>>> a
[{'hello': 5}, {'hello': 5}, {'hello': 5}]
>>>
So each dictionary refers to the same object. Same holds true if you initialize with arrays or objects.
You could do this instead:
>>> b = [{} for i in range(0, 3)]
>>> b
[{}, {}, {}]
>>> b[0]['hello'] = 6
>>> b
[{'hello': 6}, {}, {}]
>>>
Perhaps your subquery (SELECT ename FROM EMP WHERE empno = mgr)
thinks, give me the employee records that are their own managers! (i.e., where the empno of a row is the same as the mgr of the same row.)
have you considered perhaps rewriting this to use an inner (self) join? (I'm asking, becuase i'm not even sure if the following will work or not.)
SELECT t1.ename, t1.empno, t2.ename as MANAGER, t1.mgr
from emp as t1
inner join emp t2 ON t1.mgr = t2.empno
order by t1.empno;

Take a look at OPENROWSET
, and do something like:
SELECT * INTO #TEMPTABLE FROM OPENROWSET('SQLNCLI'
, 'Server=(local)\SQL2008;Trusted_Connection=yes;',
'SELECT * FROM ' + @tableName)
If the lists allow duplicate elements, you can use Counter from collections:
from collections import Counter
result = list((Counter(x)-Counter(y)).elements())
If you need to preserve the order of elements from x:
result = [ v for c in [Counter(y)] for v in x if not c[v] or c.subtract([v]) ]
I had this problem and just decided to rename one of the programs from python.exe to python2.7.exe. Now I can specify on command prompt which program to run easily without introducing any scripts or changing environmental paths. So i have two programs: python2.7 and python (the latter which is v.3.8 aka default).

timespec_get
from C11
Returns up to nanoseconds, rounded to the resolution of the implementation.
Looks like an ANSI ripoff from POSIX' clock_gettime
.
Example: a printf
is done every 100ms on Ubuntu 15.10:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
static long get_nanos(void) {
struct timespec ts;
timespec_get(&ts, TIME_UTC);
return (long)ts.tv_sec * 1000000000L + ts.tv_nsec;
}
int main(void) {
long nanos;
long last_nanos;
long start;
nanos = get_nanos();
last_nanos = nanos;
start = nanos;
while (1) {
nanos = get_nanos();
if (nanos - last_nanos > 100000000L) {
printf("current nanos: %ld\n", nanos - start);
last_nanos = nanos;
}
}
return EXIT_SUCCESS;
}
The C11 N1570 standard draft 7.27.2.5 "The timespec_get function says":
If base is TIME_UTC, the tv_sec member is set to the number of seconds since an implementation defined epoch, truncated to a whole value and the tv_nsec member is set to the integral number of nanoseconds, rounded to the resolution of the system clock. (321)
321) Although a struct timespec object describes times with nanosecond resolution, the available resolution is system dependent and may even be greater than 1 second.
C++11 also got std::chrono::high_resolution_clock
: C++ Cross-Platform High-Resolution Timer
glibc 2.21 implementation
Can be found under sysdeps/posix/timespec_get.c
as:
int
timespec_get (struct timespec *ts, int base)
{
switch (base)
{
case TIME_UTC:
if (__clock_gettime (CLOCK_REALTIME, ts) < 0)
return 0;
break;
default:
return 0;
}
return base;
}
so clearly:
only TIME_UTC
is currently supported
it forwards to __clock_gettime (CLOCK_REALTIME, ts)
, which is a POSIX API: http://pubs.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html
Linux x86-64 has a clock_gettime
system call.
Note that this is not a fail-proof micro-benchmarking method because:
man clock_gettime
says that this measure may have discontinuities if you change some system time setting while your program runs. This should be a rare event of course, and you might be able to ignore it.
this measures wall time, so if the scheduler decides to forget about your task, it will appear to run for longer.
For those reasons getrusage()
might be a better better POSIX benchmarking tool, despite it's lower microsecond maximum precision.
More information at: Measure time in Linux - time vs clock vs getrusage vs clock_gettime vs gettimeofday vs timespec_get?

Recently discovered that a third party library - Square Retrofit can do the job very well.
Defining REST endpoint
public interface GitHubService {
@GET("/users/{user}/repos")
List<Repo> listRepos(@Path("user") String user,Callback<List<User>> cb);
}
Getting the concrete service
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("https://api.github.com")
.build();
GitHubService service = restAdapter.create(GitHubService.class);
Calling the REST endpoint
List<Repo> repos = service.listRepos("octocat",new Callback<List<User>>() {
@Override
public void failure(final RetrofitError error) {
android.util.Log.i("example", "Error, body: " + error.getBody().toString());
}
@Override
public void success(List<User> users, Response response) {
// Do something with the List of Users object returned
// you may populate your adapter here
}
});
The library handles the json serialization and deserailization for you. You may customize the serialization and deserialization too.
Gson gson = new GsonBuilder()
.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
.registerTypeAdapter(Date.class, new DateTypeAdapter())
.create();
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("https://api.github.com")
.setConverter(new GsonConverter(gson))
.build();

You need to run
git remote update
or
git remote update <remote>
Then you can run git branch -r
to list the remote branches.
To track a (new) remote branch as a local branch:
git checkout -b <local branch> <remote>/<remote branch>
or (sometimes it doesn't work without the extra remotes/
):
git checkout -b <local branch> remotes/<remote>/<remote branch>

For an incoming request like /v1/location/1234
, as you can imagine it would be difficult for Web API to automatically figure out if the value of the segment corresponding to '1234' is related to appid
and not to deviceid
.
I think you should change your route template to be like
[Route("v1/location/{deviceOrAppid?}", Name = "AddNewLocation")]
and then parse the deiveOrAppid
to figure out the type of id.
Also you need to make the segments in the route template itself optional otherwise the segments are considered as required. Note the ?
character in this case.
For example:
[Route("v1/location/{deviceOrAppid?}", Name = "AddNewLocation")]
This would be the easier way to do it using aggregate
:
db.contest.aggregate([
{"$group" : {_id:"$province", count:{$sum:1}}}
])
$sth = mysqli_query($conn, "SELECT ...");
$rows = array();
while($r = mysqli_fetch_assoc($sth)) {
$rows[] = $r;
}
print json_encode($rows);
The function json_encode
needs PHP >= 5.2 and the php-json package - as mentioned here
NOTE: mysql
is deprecated as of PHP 5.5.0, use mysqli
extension instead http://php.net/manual/en/migration55.deprecated.php.
Difference between a Spy and a Mock
When Mockito creates a mock – it does so from the Class of a Type, not from an actual instance. The mock simply creates a bare-bones shell instance of the Class, entirely instrumented to track interactions with it. On the other hand, the spy will wrap an existing instance. It will still behave in the same way as the normal instance – the only difference is that it will also be instrumented to track all the interactions with it.
In the following example – we create a mock of the ArrayList class:
@Test
public void whenCreateMock_thenCreated() {
List mockedList = Mockito.mock(ArrayList.class);
mockedList.add("one");
Mockito.verify(mockedList).add("one");
assertEquals(0, mockedList.size());
}
As you can see – adding an element into the mocked list doesn’t actually add anything – it just calls the method with no other side-effect. A spy on the other hand will behave differently – it will actually call the real implementation of the add method and add the element to the underlying list:
@Test
public void whenCreateSpy_thenCreate() {
List spyList = Mockito.spy(new ArrayList());
spyList.add("one");
Mockito.verify(spyList).add("one");
assertEquals(1, spyList.size());
}
Here we can surely say that the real internal method of the object was called because when you call the size() method you get the size as 1, but this size() method isn’t been mocked! So where does 1 come from? The internal real size() method is called as size() isn’t mocked (or stubbed) and hence we can say that the entry was added to the real object.

If every input asks the same question, you should use a for
loop and an array of inputs:
Scanner dd = new Scanner(System.in);
int[] vars = new int[3];
for(int i = 0; i < vars.length; i++) {
System.out.println("Enter next var: ");
vars[i] = dd.nextInt();
}
Or as Chip suggested, you can parse the input from one line:
Scanner in = new Scanner(System.in);
int[] vars = new int[3];
System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
vars[i] = in.nextInt();
You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.
If a function does not return anything, e.g.:
def test():
pass
it has an implicit return value of None
.
Thus, as your pick*
methods do not return anything, e.g.:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
the lines that call them, e.g.:
word = pickEasy()
set word
to None
, so wordInput
in getInput
is None
. This means that:
if guess in wordInput:
is the equivalent of:
if guess in None:
and None
is an instance of NoneType
which does not provide iterator/iteration functionality, so you get that type error.
The fix is to add the return type:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
Case 1: Don’t care about local changes
Solution 1: Get the latest code and reset the code
git fetch origin
git reset --hard origin/[tag/branch/commit-id usually: master]
Solution 2: Delete the folder and clone again :D
rm -rf [project_folder]
git clone [remote_repo]
Case 2: Care about local changes
Solution 1: no conflicts with new-online version
git fetch origin
git status
will report something like:
Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded.
Then get the latest version
git pull
Solution 2: conflicts with new-online version
git fetch origin
git status
will report something like:
error: Your local changes to the following files would be overwritten by merge:
file_name
Please, commit your changes or stash them before you can merge.
Aborting
Commit your local changes
git add .
git commit -m ‘Commit msg’
Try to get the changes (will fail)
git pull
will report something like:
Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>'
as appropriate to mark resolution, or use 'git commit -a'.
Open the conflict file and fix the conflict. Then:
git add .
git commit -m ‘Fix conflicts’
git pull
will report something like:
Already up-to-date.
More info: How do I use 'git reset --hard HEAD' to revert to a previous commit?
It will be bigger in base64.
Base64 uses 6 bits per byte to encode data, whereas binary uses 8 bits per byte. Also, there is a little padding overhead with Base64. Not all bits are used with Base64 because it was developed in the first place to encode binary data on systems that can only correctly process non-binary data.
That means that the encoded image will be around 33%-36% larger (33% from not using 2 of the bits per byte, plus possible padding accounting for the remaining 3%).
I started with johncarls solution, but needed to adjust it to get exactly what I needed. Mainly, I needed it to rotate clockwise when the angle increased. I also needed 0 degrees to point NORTH. His solution got me close, but I decided to post my solution as well in case it helps anyone else.
I've added some additional comments to help explain my understanding of the function in case you need to make simple modifications.
/**
* Calculates the angle from centerPt to targetPt in degrees.
* The return should range from [0,360), rotating CLOCKWISE,
* 0 and 360 degrees represents NORTH,
* 90 degrees represents EAST, etc...
*
* Assumes all points are in the same coordinate space. If they are not,
* you will need to call SwingUtilities.convertPointToScreen or equivalent
* on all arguments before passing them to this function.
*
* @param centerPt Point we are rotating around.
* @param targetPt Point we want to calcuate the angle to.
* @return angle in degrees. This is the angle from centerPt to targetPt.
*/
public static double calcRotationAngleInDegrees(Point centerPt, Point targetPt)
{
// calculate the angle theta from the deltaY and deltaX values
// (atan2 returns radians values from [-PI,PI])
// 0 currently points EAST.
// NOTE: By preserving Y and X param order to atan2, we are expecting
// a CLOCKWISE angle direction.
double theta = Math.atan2(targetPt.y - centerPt.y, targetPt.x - centerPt.x);
// rotate the theta angle clockwise by 90 degrees
// (this makes 0 point NORTH)
// NOTE: adding to an angle rotates it clockwise.
// subtracting would rotate it counter-clockwise
theta += Math.PI/2.0;
// convert from radians to degrees
// this will give you an angle from [0->270],[-180,0]
double angle = Math.toDegrees(theta);
// convert to positive range [0-360)
// since we want to prevent negative angles, adjust them now.
// we can assume that atan2 will not return a negative value
// greater than one partial rotation
if (angle < 0) {
angle += 360;
}
return angle;

Python 2.5 includes an uuid implementation which (in at least one version) needs the mac address. You can import the mac finding function into your own code easily:
from uuid import getnode as get_mac
mac = get_mac()
The return value is the mac address as 48 bit integer.
A lot of answers already, but unfortunately most of them are just tiny economies on a barely optimizable problem...
I worked on several projects where line count was the core function of the software, and working as fast as possible with a huge number of files was of paramount importance.
The main bottleneck with line count is I/O access, as you need to read each line in order to detect the line return character, there is simply no way around. The second potential bottleneck is memory management: the more you load at once, the faster you can process, but this bottleneck is negligible compared to the first.
Hence, there are 3 major ways to reduce the processing time of a line count function, apart from tiny optimizations such as disabling gc collection and other micro-managing tricks:
Hardware solution: the major and most obvious way is non-programmatic: buy a very fast SSD/flash hard drive. By far, this is how you can get the biggest speed boosts.
Data preparation solution: if you generate or can modify how the files you process are generated, or if it's acceptable that you can pre-process them, first convert the line return to unix style (\n
) as this will save 1 character compared to Windows or MacOS styles (not a big save but it's an easy gain), and secondly and most importantly, you can potentially write lines of fixed length. If you need variable length, you can always pad smaller lines. This way, you can calculate instantly the number of lines from the total filesize, which is much faster to access. Often, the best solution to a problem is to pre-process it so that it better fits your end purpose.
Parallelization + hardware solution: if you can buy multiple hard disks (and if possible SSD flash disks), then you can even go beyond the speed of one disk by leveraging parallelization, by storing your files in a balanced way (easiest is to balance by total size) among disks, and then read in parallel from all those disks. Then, you can expect to get a multiplier boost in proportion with the number of disks you have. If buying multiple disks is not an option for you, then parallelization likely won't help (except if your disk has multiple reading headers like some professional-grade disks, but even then the disk's internal cache memory and PCB circuitry will likely be a bottleneck and prevent you from fully using all heads in parallel, plus you have to devise a specific code for this hard drive you'll use because you need to know the exact cluster mapping so that you store your files on clusters under different heads, and so that you can read them with different heads after). Indeed, it's commonly known that sequential reading is almost always faster than random reading, and parallelization on a single disk will have a performance more similar to random reading than sequential reading (you can test your hard drive speed in both aspects using CrystalDiskMark for example).
If none of those are an option, then you can only rely on micro-managing tricks to improve by a few percents the speed of your line counting function, but don't expect anything really significant. Rather, you can expect the time you'll spend tweaking will be disproportionated compared to the returns in speed improvement you'll see.
You need to convert all the values in the column to date in order to sort by date.
Here is a simple solution to minimize changes to your code:
from datetime import datetime
import pytz
start_utc = datetime.utcnow()
print ("Time (UTC): %s" % start_utc.strftime("%d-%m-%Y %H:%M:%S"))
Time (UTC): 09-01-2021 03:49:03
tz = pytz.timezone('Africa/Cairo')
start_tz = datetime.now().astimezone(tz)
print ("Time (RSA): %s" % start_tz.strftime("%d-%m-%Y %H:%M:%S"))
Time (RSA): 09-01-2021 05:49:03

Here is a performance comparison with the Numpy's builtin indexing:

In [3]: timeit np.putmask(A, A>0.5, 5)
1000 loops, best of 3: 1.34 ms per loop
In [4]: timeit A[A > 0.5] = 5

I searched for the solution how I can insert a new row and How to set the individual values of the cells inside it like Excel. I solved with following code:
dataGridView1.ReadOnly = false; //Before modifying, it is required.
dataGridView1.Rows.Add(); //Inserting first row if yet there is no row, first row number is '0'
dataGridView1.Rows[0].Cells[0].Value = "Razib, this is 0,0!"; //Setting the leftmost and topmost cell's value (Not the column header row!)
dataGridView1[1, 0].Value = "This is 0,1!"; //Setting the Second cell of the first row!
Note:
Hope this might help you.
A quick way is to run a jQuery command in the developer console. On any browser hit F12 and try to access any of the element .

I came across same old issue and found below code more understandable which is in a way per above solutions.
std::set<int*>::iterator beginIt = listOfInts.begin();
while(beginIt != listOfInts.end())
{
// Use your member
std::cout<<(*beginIt)<<std::endl;
// delete the object
delete (*beginIt);
// erase item from vector
listOfInts.erase(beginIt );
// re-calculate the begin
beginIt = listOfInts.begin();
}
You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.
perhaps a:
i=2
while i < n:
if something:
do something
i += 1
else:
do something else
i = 2 #restart the loop
we can simply use:
public void animStart(View view) {
if(count==0){
Log.d("count", String.valueOf(count));
i1.animate().alpha(0f).setDuration(2000);
i2.animate().alpha(1f).setDuration(2000);
count =1;
}
else if(count==1){
Log.d("count", String.valueOf(count));
count =0;
i2.animate().alpha(0f).setDuration(2000);
i1.animate().alpha(1f).setDuration(2000);
}
}
where i1 and i2 are defined in the onCreateView() as:
i1 = (ImageView)findViewById(R.id.firstImage);
i2 = (ImageView)findViewById(R.id.secondImage);
count is a class variable initilaized to 0.

To remotely capture http or https traffic with charles you will need to do the following:
HOST - Machine running Charles and hosting the proxy CLIENT – User’s machine generating the traffic you will capture
Host Machine
Client Machine:
When I tested this out I picked up two lines of a Facebook HTTPS chat (one was a line TO someone, and the other FROM)
you can also capture android emulator traffic this way if you start the emulator with:
emulator -avd <avd name> -http-proxy http://local_ip:8888/
Where LOCAL_IP is the IP address of your computer, not 127.0.0.1 as that is the IP address of the emulated phone.

The equivalence would be
for i in (0...array.size)
end
or
(0...array.size).each do |i|
end
or
i = 0
while i < array.size do
array[i]
i = i + 1 # where you may freely set i to any value
end
As answered before, there are many ways of dealing with exceptions in JUnit. But with Java 8 there is another one: using Lambda Expressions. With Lambda Expressions we can achieve a syntax like this:
@Test
public void verifiesTypeAndMessage() {
assertThrown(new DummyService()::someMethod)
.isInstanceOf(RuntimeException.class)
.hasMessage("Runtime exception occurred")
.hasMessageStartingWith("Runtime")
.hasMessageEndingWith("occurred")
.hasMessageContaining("exception")
.hasNoCause();
}
assertThrown accepts a functional interface, whose instances can be created with lambda expressions, method references, or constructor references. assertThrown accepting that interface will expect and be ready to handle an exception.
This is relatively simple yet powerful technique.
Have a look at this blog post describing this technique: http://blog.codeleak.pl/2014/07/junit-testing-exception-with-java-8-and-lambda-expressions.html
The source code can be found here: https://github.com/kolorobot/unit-testing-demo/tree/master/src/test/java/com/github/kolorobot/exceptions/java8
Disclosure: I am the author of the blog and the project.
I hope you are aware about System and User environmental variables. The user ones are preferred over system. If you have set your JAVA_HOME in system variables and if there is an entry for the same in user variables, then you will get the latter one only.
Right click on My computer, Go to properties, Select Advanced tab and click on Environmental variables to see the list of user and system environment variables.
T = [L[i] for i in Idx]
You can do this with simple javascript...
<select multiple="multiple" size="return this.length();">
...or limit height until number-of-records...
<select multiple="multiple" size="return this.length() > 10 ? this.length(): 10;">
You can directly use the S3 path. I am using Pandas 0.24.1
In [1]: import pandas as pd
In [2]: df = pd.DataFrame( [ [1, 1, 1], [2, 2, 2] ], columns=['a', 'b', 'c'])
In [3]: df
Out[3]:
a b c
0 1 1 1
1 2 2 2
In [4]: df.to_csv('s3://experimental/playground/temp_csv/dummy.csv', index=False)
In [5]: pd.__version__
Out[5]: '0.24.1'
In [6]: new_df = pd.read_csv('s3://experimental/playground/temp_csv/dummy.csv')
In [7]: new_df
Out[7]:
a b c
0 1 1 1
1 2 2 2
S3 File Handling
pandas now uses s3fs for handling S3 connections. This shouldn’t break any code. However, since s3fs is not a required dependency, you will need to install it separately, like boto in prior versions of pandas. GH11915.
Add padding. Padding the element will increase the space between its content and its border. However, note that a box-shadow will begin outside the border, not the content, meaning you can't put space between the shadow and the box. Alternatively you could use :before or :after pseudo selectors on the element to create a slightly bigger box that you place the shadow on, like so: http://jsbin.com/aqemew/edit#source
I think you are asking for something like the code below:
public interface A
{
void foo()
throws AException;
}
public class B
implements A
{
@Overrides
public void foo()
throws AException,
BException
{
}
}
This will not work unless BException is a subclass of AException. When you override a method you must conform to the signature that the parent provides, and exceptions are part of the signature.
The solution is to declare the the interface also throws a BException.
The reason for this is you do not want code like:
public class Main
{
public static void main(final String[] argv)
{
A a;
a = new B();
try
{
a.foo();
}
catch(final AException ex)
{
}
// compiler will not let you write a catch BException if the A interface
// doesn't say that it is thrown.
}
}
What would happen if B::foo threw a BException? The program would have to exit as there could be no catch for it. To avoid situations like this child classes cannot alter the types of exceptions thrown (except that they can remove exceptions from the list).
Your question is asking to display two decimal places. Using the following String.format will help:
String.Format("{0:.##}", Debitvalue)
this will display then number with up to two decimal places(e.g. 2.10 would be shown as 2.1 ).
Use "{0:.00}", if you want always show two decimal places(e.g. 2.10 would be shown as 2.10 )
Or if you want the currency symbol displayed use the following:
String.Format("{0:C}", Debitvalue)
I have changed a little bit previous answer and compose WPF version of the MessageBoxEx. This code works for me great. Feel free to notify about issues of the code.
Please note:
I use GeneralObjects.MainWindowInstance
at ctor to initialize class with my main window, but actually I use it for any window due to some kind of cache for last parent window. Therefore you can simple remove out everything from ctor.

You need to put the font file name / path in quotes.
Eg.
url("../fonts/Gotham-Medium.ttf")
or
url('../fonts/Gotham-Medium.ttf')
and not
url(../fonts/Gotham-Medium.ttf)
Also @FONT-FACE
only works with some font files. :o(
All the sites where you can download fonts, never say which fonts work and which ones don't.
None of the above was suitable, without calling session_start() in all php files that depend on $Session variables they will not be included. The Notice is so annoying and quickly fill up the Error_log. The only solution that I can find that works is this....
error_reporting(E_ALL ^ E_NOTICE);
session_start();
A Bad fix , but it works.
If you are using Java 6 or higher you can use wildcards of this form:
java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp
If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:
java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp
There is nothing like lib\*\*
or lib\**
wildcard for the kind of job you want to be done.
This one works for me:
<tr style="height: 15px;"/>
On Ubuntu, after installing ZSH, and prevously on the bash
terminal installed Node or other packages,
First open:
nano .zshrc
And uncomment the second line:
export PATH=$HOME/bin:/usr/local/bin:$PATH
This works for me, and without writting any line, and I think this option is available on Mac too.
Run it on a single command line like so:
powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile
-WindowStyle Hidden -Command "Get-AppLockerFileInformation -Directory <folderpath>
-Recurse -FileType <type>"
To Increase request time out add this to web.config
<system.web>
<httpRuntime executionTimeout="180" />
</system.web>
and for a specific page add this
<location path="somefile.aspx">
<system.web>
<httpRuntime executionTimeout="180"/>
</system.web>
</location>
The default is 90 seconds for .NET 1.x.
The default 110 seconds for .NET 2.0 and later.
It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:
Access-Control-Allow-Origin:*
or
Access-Control-Allow-Origin:your domain
In Apache config files, the code is like this:
Header set Access-Control-Allow-Origin "*"
In nodejs,the code is like this:
res.setHeader('Access-Control-Allow-Origin','*');
If you are on Linux you may not have docker-machine
installed since it is only installed by default on Windows and Mac computers.
If so you will need to got to: https://docs.docker.com/machine/install-machine/ to find instructions for how to install it on your version of Linux.
After installing, retry running docker-compose up
before trying anything listed above.
Hope this helps someone. This worked for my devilbox installation in Fedora 25.
Simply saying top down approach uses recursion for calling Sub problems again and again
where as bottom up approach use the single without calling any one and hence it is more efficient.
If you really need to, you could serialize an enum as a String, using name()
and valueOf(String)
, as follows:
class Example implements Parcelable {
public enum Foo { BAR, BAZ }
public Foo fooValue;
public void writeToParcel(Parcel dest, int flags) {
parcel.writeString(fooValue == null ? null : fooValue.name());
}
public static final Creator<Example> CREATOR = new Creator<Example>() {
public Example createFromParcel(Parcel source) {
Example e = new Example();
String s = source.readString();
if (s != null) e.fooValue = Foo.valueOf(s);
return e;
}
}
}
This obviously doesn't work if your enums have mutable state (which they shouldn't, really).
I'm not familiar with tortoise, but with subversion to linux i would type
svn status
Some googling tells me that tortoise also supports commandline commandos, try svn status in the folder that contains the svn repository.
Consider using System.Windows.Forms.Timer
instead of System.Threading.Timer
for a GUI application, for timers that are based on the Windows message queue instead of on dedicated threads or the thread pool.
In your scenario, for the purpose of periodic updates of UI, it seems particularly appropriate since you don't really have a background work or long calculation to perform. You just want to do periodic small tasks that have to happen on the UI thread anyway.
This will also work:
<Hyperlink Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},
Path=DataContext.AllowItemCommand}" />
ListView
will inherit its DataContext
from Window
, so it's available at this point, too.
And since ListView
, just like similar controls (e. g. Gridview
, ListBox
, etc.), is a subclass of ItemsControl
, the Binding
for such controls will work perfectly.
var1="\t\t Test String trimming "
echo $var1
Var2=$(echo "${var1}" | sed 's/^[[:space:]]*//;s/[[:space:]]*$//')
echo $Var2
The docs are pretty clear that you pass in a second parameter to specify granularity.
If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.
moment('2010-10-20').isAfter('2010-01-01', 'year'); // false moment('2010-10-20').isAfter('2009-12-31', 'year'); // true
As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day.
For your case you would pass 'day'
as the second parameter.
This here works very good, maybe it could help anybody:

This one didn't work for me as I'm using Django 2.1.3:
import sys
sys.path.append("..") # Adds higher directory to python modules path.
I opted for a custom solution where I added a command to the server startup script to copy my shared script into the django 'app' that needed the shared python script. It's not ideal but as I'm only developing a personal website, it fit the bill for me. I will post here again if I can find the django way of sharing code between Django Apps within a single website.
I needed to rotate an object but have a call back function. Inspired by John Kern's answer I created this.
function animateRotate (object,fromDeg,toDeg,duration,callback){
var dummy = $('<span style="margin-left:'+fromDeg+'px;">')
$(dummy).animate({
"margin-left":toDeg+"px"
},
{
duration:duration,
step: function(now,fx){
$(object).css('transform','rotate(' + now + 'deg)');
if(now == toDeg){
if(typeof callback == "function"){
callback();
}
}
}
}
)};
Doing this you can simply call the rotate on the object like so... (in my case I'm doing it on a disclosure triangle icon that has already been rotated by default to 270 degress and I'm rotating it another 90 degrees to 360 degrees at 1000 milliseconds. The final argument is the callback after the animation has finished.
animateRotate($(".disclosure_icon"),270,360,1000,function(){
alert('finished rotate');
});

To update entries other than appsettings
, simply use XmlDocument
.
public static void UpdateAppConfig(string tagName, string attributeName, string value)
{
var doc = new XmlDocument();
doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
var tags = doc.GetElementsByTagName(tagName);
foreach (XmlNode item in tags)
{
var attribute = item.Attributes[attributeName];
if (!ReferenceEquals(null, attribute))
attribute.Value = value;
}
doc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
}
This is how you call it:
Utility.UpdateAppConfig("endpoint", "address", "http://localhost:19092/NotificationSvc/Notification.svc");
Utility.UpdateAppConfig("network", "host", "abc.com.au");
This method can be improved to cater for appSettings values as well.
Try this:
$arr = (array) null;
var_dump($arr);
// will print
// array(0) { }
I use the following technique. It makes it easy to keep the column names in sync with the content:
var cursor = db.getCollection('Employees.Details').find({})
var header = []
var rows = []
var firstRow = true
cursor.forEach((doc) =>
{
var cells = []
if (firstRow) header.push("employee_number")
cells.push(doc.EmpNum.valueOf())
if (firstRow) header.push("name")
cells.push(doc.FullName.valueOf())
if (firstRow) header.push("dob")
cells.push(doc.DateOfBirth.valueOf())
row = cells.join(',')
rows.push(row)
firstRow = false
})
print(header.join(','))
print(rows.join('\n'))

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>your.company</groupId>
<artifactId>company-parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<distributionManagement>
<repository>
<id>nexus-site</id>
<url>http://central_nexus/server</url>
</repository>
</distributionManagement>
</project>
This can be built, released, and deployed to your local nexus so everyone has access to its artifact.
Now for all projects which you wish to use it, simply include this section:
<parent>
<groupId>your.company</groupId>
<artifactId>company-parent</artifactId>
<version>1.0.0</version>
</parent>
This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.
If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.
I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.
- pom.xml (aggregator)
- project-parent
- project-module1
- project-module2
What you do with this structure is include your parent module in the aggregator and build everything with a mvn install
from the root directory.
We use this exact solution at my organization and it has stood the test of time and worked quite well for us.
To add a small bit to Sydius' answer, smart pointers will often provide a more stable solution by catching many easy to make errors. Raw pointers will have some perfromance advantages and can be more flexible in certain circumstances. You may also be forced to use raw pointers when linking into certain 3rd party libraries.
FLAG_ACTIVITY_REORDER_TO_FRONT: If set in an Intent passed to Context.startActivity(), this flag will cause the launched activity to be brought to the front of its task's history stack if it is already running.
Intent i = new Intent(context, AActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(i);
Something that sometimes crops up you may/maynot be aware of
Won't always be picked up by by $_POST['delete'] when using IE. Firefox and chrome should work fine though. I use a seperate isntead which solves the problem for IE
As for your not deleting in your code above you appear to be echoing out 2x sets of check boxes both pulling the same data? Is this just a copy + paste mistake or is this actually how your code is?
If its how your code is that'll be the problem as the user could be ticking one checkbox array item but the other one will be unchecked so the php code for delete is getting confused. Either rename the 2nd check box or delete that block of html surely you don't need to display the same list twice ?
You could just set the width to auto. Then the width of the div will equal 0 if it has no content.
width:auto;
It's possible by accessing the key as index
for example:
Dictionary<string, int> dictionary = new Dictionary<string, int>();
dictionary["test"] = 1;
dictionary["test"] += 1;
Console.WriteLine (dictionary["test"]); // will print 2
Unfortunately, AFAIK you cannot run multiple SQL statements under one named query in Access in the traditional sense.
You can make several queries, then string them together with VBA (DoCmd.OpenQuery
if memory serves).
You can also string a bunch of things together with UNION if you wish.
Using ToString("HH:mm")
certainly gives you what you want as a string.
If you want the current hour/minute as numbers, string manipulation isn't necessary; you can use the TimeOfDay
property:
TimeSpan timeOfDay = fechaHora.TimeOfDay;
int hour = timeOfDay.Hours;
int minute = timeOfDay.Minutes;
I like Consolas
a lot. This top-10 list is a good resource for others. It includes examples and descriptions.

@Mircea: It is very much easy to set the multiple styles for an element in a single statement. It doesn't effect the existing properties and avoids the complexity of going for loops or plugins.
document.getElementById("demo").setAttribute(
"style", "font-size: 100px; font-style: italic; color:#ff0000;");
BE CAREFUL: If, later on, you use this method to add or alter style properties, the previous properties set using 'setAttribute' will be erased.
If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.
Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.
This is the same question as Failed to connect to mailserver at "localhost" port 25
also check this php mail function not working
I like the namespace better for this kind of purpose.
Option 1 :
#ifndef MYLIB_CONSTANTS_H
#define MYLIB_CONSTANTS_H
// File Name : LibConstants.hpp Purpose : Global Constants for Lib Utils
namespace LibConstants
{
const int CurlTimeOut = 0xFF; // Just some example
...
}
#endif
// source.cpp
#include <LibConstants.hpp>
int value = LibConstants::CurlTimeOut;
Option 2 :
#ifndef MYLIB_CONSTANTS_H
#define MYLIB_CONSTANTS_H
// File Name : LibConstants.hpp Purpose : Global Constants for Lib Utils
namespace CurlConstants
{
const int CurlTimeOut = 0xFF; // Just some example
...
}
namespace MySQLConstants
{
const int DBPoolSize = 0xFF; // Just some example
...
}
#endif
// source.cpp
#include <LibConstants.hpp>
int value = CurlConstants::CurlTimeOut;
int val2 = MySQLConstants::DBPoolSize;
And I would never use a Class to hold this type of HardCoded Const variables.
Below applies to all tags with the following two classes
.abc.xyz {
width: 200px !important;
}
applies to div tags with the following two classes
div.abc.xyz {
width: 200px !important;
}
If you wanted to modify this using jQuery
$(document).ready(function() {
$("div.abc.xyz").width("200px");
});

Very simple way in codeigniter to call a method of one controller to other controller
1. Controller A
class A extends CI_Controller {
public function __construct()

}
}
2. Controller B
class B extends CI_Controller {
public function __construct()
{
parent::__construct();

require_once(APPPATH.'controllers/a.php'); //include controller
$aObj = new a(); //create object
$aObj->custom_a(); //call function
}
}
to_dict() Convert a SON document to a normal Python dictionary instance.
This is trickier than just dict(...) because it needs to be recursive.
You can try something like this. Special Characters range for alphabets starts from 192, so you can avoid such characters in the result.
String name = "A função";
StringBuilder result = new StringBuilder();
for(char val : name.toCharArray()) {
if(val < 192) result.append(val);
}
System.out.println("Result "+result.toString());
DateTime.Ticks will account for the time. Use .Ticks on the DateTime to convert your dates into longs. Then just use a simple if stmt to see if your target date falls between.
// Assuming you know d2 > d1
if (targetDt.Ticks > d1.Ticks && targetDt.Ticks < d2.Ticks)
{
// targetDt is in between d1 and d2
}
Thank you for your answers! They definitely led me on the right track. But none of them completely got me everything I wanted, so here's what I actually ended up doing.
The key piece of information I was missing was that I needed to put the data together in one big block, but I could still leave empty cells in it. Something like this:
Date Actual remaining Desired remaining
7/13/2009 7350 7350
7/15/2009 7100
7/21/2009 7150
7/23/2009 6600
7/27/2009 6550
8/8/2009 6525
8/16/2009 6200
11/3/2009 0
Now I have something Excel is a little better at charting. So long as I set the chart options to "Show empty cells as: Connect data points with line," it ends up looking pretty nice. Using the above test data:
Then I just needed my update macro to insert new rows above the last one to fill in new data whenever I want. My macro looks something like this:
' Find the last cell on the left going down. This will be the last cell
' in the "Date" column
Dim left As Range
Set left = Range("A1").End(xlDown)
' Move two columns to the right and select so we have the 3 final cells,
' including "Date", "Actual remaining", and "Desired remaining"
Dim bottom As Range
Set bottom = Range(left.Cells(1), left.Offset(0, 2))
' Insert a new blank row, and then move up to account for it
bottom.Insert (xlShiftDown)
Set bottom = bottom.Offset(-1)
' We are now sitting on some blank cells very close to the end of the data,
' and are ready to paste in new values for the date and new pages remaining
' (I do this by grabbing some other cells and doing a PasteSpecial into bottom)
Improvement suggestions on that macro are welcome. I just fiddled with it until it worked.
Now I have a pretty chart and I can nerd out all I want with my nerdy books for nerds.
Any number of files in a directory are a single package; symbols declared in one file are available to the others without any import
s or qualifiers. All of the files do need the same package foo
declaration at the top (or you'll get an error from go build
).
You do need GOPATH
set to the directory where your pkg
, src
, and bin
directories reside. This is just a matter of preference, but it's common to have a single workspace for all your apps (sometimes $HOME
), not one per app.
Normally a Github path would be github.com/username/reponame
(not just github.com/xxxx
). So if you want to have main
and another package, you may end up doing something under workspace/src
like
github.com/
username/
reponame/
main.go // package main, importing "github.com/username/reponame/b"
b/
b.go // package b
Note you always import with the full github.com/...
path: relative imports aren't allowed in a workspace. If you get tired of typing paths, use goimports
. If you were getting by with go run
, it's time to switch to go build
: run
deals poorly with multiple-file main
s and I didn't bother to test but heard (from Dave Cheney here) go run
doesn't rebuild dirty dependencies.
Sounds like you've at least tried to set GOPATH to the right thing, so if you're still stuck, maybe include exactly how you set the environment variable (the command, etc.) and what command you ran and what error happened. Here are instructions on how to set it (and make the setting persistent) under Linux/UNIX and here is the Go team's advice on workspace setup. Maybe neither helps, but take a look and at least point to which part confuses you if you're confused.
They are equivalent, from the standard (emphasis mine) (7.1.3.2):
A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.
In my opinion you should use Wix#, which nicely hides most of the complexity of building an MSI installation pacakge.
It allows you to perform all possible kinds of customization using a more easier language compared to WiX.
amount = list()
for col in df.columns:
val = list(df[col])
for v in val:
amount.append(v)
Removing Language="c#" in global.asax file resolved the issue for me.
I'm a fan of the !$
, !^
and !*
expandos, returning, from the most recent submitted command line: the last item, first non-command item, and all non-command items. To wit (Note that the shell prints out the command first):
$ echo foo bar baz
foo bar baz
$ echo bang-dollar: !$ bang-hat: !^ bang-star: !*
echo bang-dollar: baz bang-hat: foo bang-star: foo bar baz
bang-dollar: baz bang-hat: foo bang-star: foo bar baz
This comes in handy when you, say ls filea fileb
, and want to edit one of them: vi !$
or both of them: vimdiff !*
. It can also be generalized to "the n
th argument" like so:
$ echo foo bar baz
$ echo !:2
echo bar
bar
Finally, with pathnames, you can get at parts of the path by appending :h
and :t
to any of the above expandos:
$ ls /usr/bin/id
/usr/bin/id
$ echo Head: !$:h Tail: !$:t
echo Head: /usr/bin Tail: id
Head: /usr/bin Tail: id
I'd like to add to the other answers this pretty new solution:
If you don't want the element to become inline-block, you can do this:
.parent{
width: min-content;
}
The support is increasing fast, so when edge decides to implement it, it will be really great: http://caniuse.com/#search=intrinsic
Seems like this is ought to be the approved answer...
Intl.NumberFormat('en-US').format(count)
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat
I had the same problem but none of the answers above worked. The solution for me was to restore the Manager web application that is bundled with Tomcat.
I had a ./Views/Web.Config
file but this error happened after publishing the site. Turns out the build action property on the file was set to None
instead of Content
. Changing this to Content
allowed publishing to work correctly.
With this method Integer.toHexString, you can have an Unknown color exception for some colors when using Color.parseColor.
And with this method String.format("#%06X", (0xFFFFFF & intColor)), you'll lose alpha value.
So I recommend this method:
public static String ColorToHex(int color) {
int alpha = android.graphics.Color.alpha(color);
int blue = android.graphics.Color.blue(color);
int green = android.graphics.Color.green(color);
int red = android.graphics.Color.red(color);
String alphaHex = To00Hex(alpha);
String blueHex = To00Hex(blue);
String greenHex = To00Hex(green);
String redHex = To00Hex(red);
// hexBinary value: aabbggrr
StringBuilder str = new StringBuilder("#");
str.append(alphaHex);
str.append(blueHex);
str.append(greenHex);
str.append(redHex );
return str.toString();
}
private static String To00Hex(int value) {
String hex = "00".concat(Integer.toHexString(value));
return hex.substring(hex.length()-2, hex.length());
}
Actually I tried creating empty stdClass and compared the speed to empty class.
class emp{}
then proceeded creating 1000 stdClasses and emps... empty classes were done in around 1100 microseconds while stdClasses took over 1700 microseconds. So I guess its better to create your own dummy class for storing data if you want to use objects for that so badly (arrays are a lot faster for both writing and reading).
If you want to refer to calculated column on the "same query level" then you could use CROSS APPLY
(Oracle 12c):
--Sample data:
CREATE TABLE tab(ColumnA NUMBER(10,2),ColumnB NUMBER(10,2),ColumnC NUMBER(10,2));
INSERT INTO tab(ColumnA, ColumnB, ColumnC) VALUES (2, 10, 2);
INSERT INTO tab(ColumnA, ColumnB, ColumnC) VALUES (3, 15, 6);
INSERT INTO tab(ColumnA, ColumnB, ColumnC) VALUES (7, 14, 3);
COMMIT;
Query:
SELECT
ColumnA,
ColumnB,
sub.calccolumn1,
sub.calccolumn1 / ColumnC AS calccolumn2
FROM tab t
CROSS APPLY (SELECT t.ColumnA + t.ColumnB AS calccolumn1 FROM dual) sub;
Please note that expression from CROSS APPLY/OUTER APPLY
is available in other clauses too:
SELECT
ColumnA,
ColumnB,
sub.calccolumn1,
sub.calccolumn1 / ColumnC AS calccolumn2
FROM tab t
CROSS APPLY (SELECT t.ColumnA + t.ColumnB AS calccolumn1 FROM dual) sub
WHERE sub.calccolumn1 = 12;
-- GROUP BY ...
-- ORDER BY ...;
This approach allows to avoid wrapping entire query with outerquery or copy/paste same expression in multiple places(with complex one it could be hard to maintain).

None of the above fixes worked for me.
What worked for me was changing
<item name="android:textColorSecondary">#FFFFFF</item>
to
<item name="android:textColorSecondary">@color/colorWhite</item>
You obviously need to add colorWhite to your colors.xml
Is there any good example to give the difference between a 'struct' and a 'union'?
An imaginary communications protocol
struct packetheader {
int sourceaddress;
int destaddress;
int messagetype;
union request {
char fourcc[4];
int requestnumber;
};
};
In this imaginary protocol, it has been sepecified that, based on the "message type", the following location in the header will either be a request number, or a four character code, but not both. In short, unions allow for the same storage location to represent more than one data type, where it is guaranteed that you will only want to store one of the types of data at any one time.
Unions are largely a low-level detail based in C's heritage as a system programming language, where "overlapping" storage locations are sometimes used in this way. You can sometimes use unions to save memory where you have a data structure where only one of several types will be saved at one time.
In general, the OS doesn't care or know about structs and unions -- they are both simply blocks of memory to it. A struct is a block of memory that stores several data objects, where those objects don't overlap. A union is a block of memory that stores several data objects, but has only storage for the largest of these, and thus can only store one of the data objects at any one time.
You can set a JavaScript variable in your WepPage that gets set once it's been loaded. You could put it anywhere, but if you're using jQuery, $(document).onReady
isn't a bad place to start. If not, then you can put it in a <script>
tag at the bottom of the page.
The advantage of this method as opposed to checking for element visibility is that you know the exact state of the page after the wait
statement executes.
... All my page content ...
<script> window.TestReady = true; </script></body></html>
And in your test (C# example):
// The timespan determines how long to wait for any 'condition' to return a value
// If it is exceeded an exception is thrown.
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5.0));
// Set the 'condition' as an anonymous function returning a boolean
wait.Until<Boolean>(delegate(IWebDriver d)
{
// Check if our global variable is initialized by running a little JS
return (Boolean)((IJavaScriptExecutor)d).ExecuteScript("return typeof(window.TestReady) !== 'undefined' && window.TestReady === true");
});
Try JSONP.
most JS libraries make it just as easy as other AJAX calls, but internally use an iframe to do the query.
if you're not using JSON for your payload, then you'll have to roll your own mechanism around the iframe.
personally, i'd just redirect form the http:// page to the https:// one
You can apply only to certain attribute by doing:
input[type="checkbox"] {...}
It explains it here.
Yes.
Yes it is.
Vanilla JS is always more efficient.
My problem is a bit different as I wanted to collect both stdout and stderr from a running process, but ultimately the same since I wanted to render the output in a widget as its generated.
I did not want to resort to many of the proposed workarounds using Queues or additional Threads as they should not be necessary to perform such a common task as running another script and collecting its output.
After reading the proposed solutions and python docs I resolved my issue with the implementation below. Yes it only works for POSIX as I'm using the select
function call.
I agree that the docs are confusing and the implementation is awkward for such a common scripting task. I believe that older versions of python have different defaults for Popen
and different explanations so that created a lot of confusion. This seems to work well for both Python 2.7.12 and 3.5.2.
The key was to set bufsize=1
for line buffering and then universal_newlines=True
to process as a text file instead of a binary which seems to become the default when setting bufsize=1
.
class workerThread(QThread):
def __init__(self, cmd):
QThread.__init__(self)
self.cmd = cmd
self.result = None ## return code
self.error = None ## flag indicates an error
self.errorstr = "" ## info message about the error
def __del__(self):
self.wait()
DEBUG("Thread removed")
def run(self):
cmd_list = self.cmd.split(" ")
try:
cmd = subprocess.Popen(cmd_list, bufsize=1, stdin=None
, universal_newlines=True
, stderr=subprocess.PIPE
, stdout=subprocess.PIPE)
except OSError:
self.error = 1
self.errorstr = "Failed to execute " + self.cmd
ERROR(self.errorstr)
finally:
VERBOSE("task started...")
import select
while True:
try:
r,w,x = select.select([cmd.stdout, cmd.stderr],[],[])
if cmd.stderr in r:
line = cmd.stderr.readline()
if line != "":
line = line.strip()
self.emit(SIGNAL("update_error(QString)"), line)
if cmd.stdout in r:
line = cmd.stdout.readline()
if line == "":
break
line = line.strip()
self.emit(SIGNAL("update_output(QString)"), line)
except IOError:
pass
cmd.wait()
self.result = cmd.returncode
if self.result < 0:
self.error = 1
self.errorstr = "Task terminated by signal " + str(self.result)
ERROR(self.errorstr)
return
if self.result:
self.error = 1
self.errorstr = "exit code " + str(self.result)
ERROR(self.errorstr)
return
return
ERROR, DEBUG and VERBOSE are simply macros that print output to the terminal.
This solution is IMHO 99.99% effective as it still uses the blocking readline
function, so we assume the sub process is nice and outputs complete lines.
I welcome feedback to improve the solution as I am still new to Python.
Use "git checkout -- ..." to discard changes in working directory
git checkout -- app/views/posts/index.html.erb
or
git checkout -- *
removes all changes made to unstaged files in git status eg
modified: app/controllers/posts.rb
modified: app/views/posts/index.html.erb
The answer is to place the root dir to the location directives:
root /srv/www/ducklington.org/public_html;
Being old-fashioned I've always used the 'document.myform.myvar' syntax but I recently found it failed in Chrome (OK in Firefox and IE). It was an Ajax page (i.e. loaded into the innerHTML property of a div). Maybe Chrome didn't recognise the form as an element of the main document. I used getElementById (without referencing the form) instead and it worked OK.
Once an instance has been started, there is no way to change the keypair associated with the instance at a meta data level, but you can change what ssh key you use to connect to the instance.

When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested
This can be achieved using column-count css property on parent div,
like
column-count:2;
check this out for more details.
I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:
GET approach with JSON result
curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool
POST approach with JSON result
curl -X POST -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool
I like @Omry Yadan's solution but I think it can be improved upon to use a loop in case you want to continue traversing up the directory tree until you find where wp-config.php
actually lives. Of course, if you don't find it and end up in the server's root then all is lost and we return a sane value (false
).
function wp_get_web_root() {
$base = dirname(__FILE__);
$path = false;
while(!$path && '/' != $base) {
if(@file_exists(dirname($base)).'/wp-config.php') {
$path = dirname($base);
} else {
$base = dirname($base);
}
}
return $path;
}
If you're encoding a string to put in a URL component (a querystring parameter), you should call encodeURIComponent
.
If you're encoding an existing URL, call encodeURI
.
IN completion to above answers, you can also customize your fallbacks for each async call you do, so that each call to the generic ASYNC method will populate different data, depending on the onTaskDone stuff you put there.
Main.FragmentCallback FC= new Main.FragmentCallback(){
@Override
public void onTaskDone(String results) {
localText.setText(results); //example TextView
}
};
new API_CALL(this.getApplicationContext(), "GET",FC).execute("&Books=" + Main.Books + "&args=" + profile_id);
Remind: I used interface on the main activity thats where "Main" comes, like this:
public interface FragmentCallback {
public void onTaskDone(String results);
}
My API post execute looks like this:
@Override
protected void onPostExecute(String results) {
Log.i("TASK Result", results);
mFragmentCallback.onTaskDone(results);
}
The API constructor looks like this:
class API_CALL extends AsyncTask<String,Void,String> {
private Main.FragmentCallback mFragmentCallback;
private Context act;
private String method;
public API_CALL(Context ctx, String api_method,Main.FragmentCallback fragmentCallback) {
act=ctx;
method=api_method;
mFragmentCallback = fragmentCallback;
}
Very easy:
Here is what you want:
import os.path as path
two_up = path.abspath(path.join(__file__ ,"../.."))
In C language, character literal is not a char
type. C considers character literal as integer. So, there is no difference between sizeof('a')
and sizeof(1)
.
So, the sizeof character literal is equal to sizeof integer in C.
In C++ language, character literal is type of char
. The cppreference say's:
1) narrow character literal or ordinary character literal, e.g.
'a'
or'\n'
or'\13'
. Such literal has typechar
and the value equal to the representation of c-char in the execution character set. If c-char is not representable as a single byte in the execution character set, the literal has type int and implementation-defined value.
So, in C++ character literal is a type of char
. so, size of character literal in C++ is one byte.
Alos, In your programs, you have used wrong format specifier for sizeof
operator.
C11 §7.21.6.1 (P9) :
If a conversion specification is invalid, the behavior is undefined.275) If any argument is not the correct type for the corresponding conversion specification, the behavior is undefined.
So, you should use %zu
format specifier instead of %d
, otherwise it is undefined behaviour in C.
Saving to Hive is just a matter of using write()
method of your SQLContext:
df.write.saveAsTable(tableName)
From Spark 2.2: use DataSet instead DataFrame.
Why so complicated?
I solved my problem this way simply:
<pre>{{existingCategory+thisCategory}}</pre>
It will make <br />
automatically if the string contains '\n' that contain when I was saving data from textarea.
Visibility : Hidden Vs Collapsed
Consider following code which only shows three Labels
and has second Label
visibility
as Collapsed
:
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center">
<StackPanel.Resources>
<Style TargetType="Label">
<Setter Property="Height" Value="30" />
<Setter Property="Margin" Value="0"/>
<Setter Property="BorderBrush" Value="Black"/>
<Setter Property="BorderThickness" Value="1" />
</Style>
</StackPanel.Resources>
<Label Width="50" Content="First"/>
<Label Width="50" Content="Second" Visibility="Collapsed"/>
<Label Width="50" Content="Third"/>
</StackPanel>
Output Collapsed:
Now change the second Label
visibility
to Hiddden
.
<Label Width="50" Content="Second" Visibility="Hidden"/>
Output Hidden:
As simple as that.
Another example to illustrate the __declspec keyword:
When you are writing a Windows Kernel Driver, sometimes you want to write your own prolog/epilog code sequences using inline assembler code, so you could declare your function with the naked attribute.
__declspec( naked ) int func( formal_parameters ) {}
Or
#define Naked __declspec( naked )
Naked int func( formal_parameters ) {}
Please refer to naked (C++)
Add line break to ::after
or ::before
pseudo-element content
.yourclass:before {
content: 'text here first \A text here second';
white-space: pre;
}
From a comment:
I want to sort each set.
That's easy. For any set s
(or anything else iterable), sorted(s)
returns a list of the elements of s
in sorted order:
>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']
Note that sorted
is giving you a list
, not a set
. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2}
and {2, 1}
are the same set.
You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).
The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key
function:
>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']
For more information, see the Sorting HOWTO in the official docs.

Its really helped me to dynamically generate ids of showDetailItem
for the below code.
<af:forEach id="fe1" items="#{viewScope.bean.tranTypeList}" var="ttf" varStatus="ttfVs" >
<af:showDetailItem id ="divIDNo${ttfVs.count}" text="#{ttf.trandef}"......>
if you execute this line <af:outputText value="#{ttfVs}"/>
prints the below:
{index=3, count=4, last=false, first=false, end=8, step=1, begin=0}
In my case on macOS I solved it with:
brew link libtool
I like to use:
git diff HEAD^
Or if I only want to diff a specific file:
git diff HEAD^ -- /foo/bar/baz.txt
Run the following command, replacing PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA
with the path to the file you want to remove, not just its filename. These arguments will:
git filter-branch --force --index-filter "git rm --cached --ignore-unmatch PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA" --prune-empty --tag-name-filter cat -- --all
This will forcefully remove all references to the files from the active history of the repo.
Next step, to perform a GC cycle to force all references to the file to be expired and purged from the pack file. Nothing needs to be replaced in these commands.
git update-ref -d refs/original/refs/remotes/origin/master
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --aggressive --prune=now
.exe - the 'normal' executable
.vshost.exe - a special version of the executable to aid debuging; see MSDN for details
.pdb - the Program Data Base with debug symbols
.vshost.exe.manifest - a kind of configuration file containing mostly dependencies on libraries
I'm doing it this way:
function f(data,d){
console.log(d);
console.log(data);
}
$.ajax({
url:u,
success:function(data){ f(data,d); }
});
TreeSet sortedset = new TreeSet();
sortedset.addAll(originalset);
list.addAll(sortedset);
where originalset = unsorted set and list = the list to be returned
What moves origin/HEAD "organically"?
git clone
sets it once to the spot where HEAD is on origin
git clone
What does HEAD on origin represent?
git clone
uses it in such a wayWhat sets origin/HEAD?
git clone
fetches and sets itgit fetch
updates it like any other reference, but it doesn’tgit remote set-head origin -a
fetches and sets it
Trivia
origin/HEAD
can also be set to any other value without contacting the remote: git remote set-head origin <branch>
Using Windows 10 Home edition. I was unable to get my event viewer to capture events 4800 and 4801, even after installing the Windows Group Policy Editor, enabling auditing on all the relevant events, and restarting the computer. However, I was able to discover other events that are tied to locking and unlocking that you can use as accurate and reliable indicators of when the PC was locked. See configurations below - the first is for PC Locked (the event connected to displaying C:\Windows\System32\LogonUI.exe) - and the second is for PC Unlocked (the event for successful logon).
The first line would consist of 3 <div>
s. One outer that contains two inner <div>
s. The first inner <div>
would have float:left
which would make sure it stays to the left, the second would have float:right
, which would stick it to the right.
<div style="width:500;height:50"><br>
<div style="float:left" >stuff </div><br>
<div style="float:right" >stuff </div>
... obviously the inline-styling isn't the best idea - but you get the point.
2,3, and 4 would be single <div>
s.
5 would work like 1.
script for multiedit command
multiedit [-n PATTERN] OLDSTRING NEWSTRING
From Kaspar's answer I made a bash script to accept command line arguments and optionally limit the filenames matching a pattern. Save in your $PATH and make executable, then just use the command above.
Here's the script:
#!/bin/bash
_help="\n
Replace OLDSTRING with NEWSTRING recursively starting from current directory\n
multiedit [-n PATTERN] OLDSTRING NEWSTRING\n
[-n PATTERN] option limits to filenames matching PATTERN\n
Note: backslash escape special characters\n
Note: enclose STRINGS with spaces in double quotes\n
Example to limit the edit to python files:\n
multiedit -n \*.py \"OLD STRING\" NEWSTRING\n"
# ensure correct number of arguments, otherwise display help...
if [ $# -lt 2 ] || [ $# -gt 4 ]; then echo -e $_help ; exit ; fi
if [ $1 == "-n" ]; then # if -n option is given:
# replace OLDSTRING with NEWSTRING recursively in files matching PATTERN
find ./ -type f -name "$2" -exec sed -i "s/$3/$4/g" {} \;
else
# replace OLDSTRING with NEWSTRING recursively in all files
find ./ -type f -exec sed -i "s/$1/$2/" {} \;
fi
I believe that it has to do with time-zone adjustment. The date you've created is in GMT and the default time is midnight, but your timezone is EDT, so it subtracts 4 hours. Try this to verify:
var doo = new Date("2011-09-25 EDT");
As @Agent_9191 and @partick mentioned you should use
$('tbody :visible').highlight(myArray[i]); // works for all children of tbody that are visible
or
$('tbody:visible').highlight(myArray[i]); // works for all visible tbodys
Additionally, since you seem to be applying a class to the highlighted words, instead of using jquery to alter the background for all matched highlights, just create a css rule with the background color you need and it gets applied directly once you assign the class.
.highlight { background-color: #FFFF88; }
