@Luch Filip's solution works well if you just want to rename the App package. In my case, I also want to rename the source package too, so as not to confuse things.
Only 2 steps are needed:
Click on your source folder e.g. com.company.example
> Shift + F6 (Refactor->Rename...) > Rename Package > enter your desired name.
Go to your AndroidManifest.xml, click on your package name > Shift + F6 (Refactor->Rename...) > enter same name as above.
Step 1 will automatically rename your R.java folder, and you can build straight away.
In your code, try enclosing password inside single quote. Alternatively, as per the documentation of mysql, following should work -
SET PASSWORD FOR 'jeffrey'@'localhost' = PASSWORD('cleartext password');
FLUSH PRIVILEGES;
The last line is important or else your password change won't take effect unfortunately.
EDIT:
I ran a test in my local and it worked -
mysql> set password for 'test' = PASSWORD('$w0rdf1sh');
Query OK, 0 rows affected (0.00 sec)
Mine is version 5. You can use following command to determine your version -
SHOW VARIABLES LIKE "%version%";
Building on @yunzen's great answer:
I'm guessing many people searching for this topic are trying use a large image as a "hero" background image, for example on a homepage. In this case, they would often want text to appear over the image and to have it scale down well on mobile devices.
Here is the perfect CSS for such a background image (use it on the <img>
tag):
/* Set left edge of inner element to 50% of the parent element */
margin-left: 50%;
/* Move to the left by 50% of own width */
transform: translateX(-50%);
/* Scale image...(101% - instead of 100% - avoids possible 1px white border on left of image due to rounding error */
width: 101%;
/* ...but don't scale it too small on mobile devices - adjust this as needed */
min-width: 1086px;
/* allow content below image to appear on top of image */
position: absolute;
z-index: -1;
/* OPTIONAL - try with/without based on your needs */
top: 0;
/* OPTIONAL - use if your outer element containing the img has "text-align: center" */
left: 0;
In Visual Studio 2017, "TestContext" doesn't show the Output link into Test Explorer.
However, Trace.Writeline() shows the Output link.
I was trying something like this using the $(...).val()
function, but the function did not exist. It turns out that you can manually set the value the same way you do it for an <input>
:
// Set value to Indonesia ("ID"):
$('#country').value = 'ID'
...and it get's automatically updated in the select. Works on Firefox at least; you might want to try it out in the others.
The @Qualifier
annotation is used to resolve the autowiring conflict, when there are multiple beans of same type.
The @Qualifier
annotation can be used on any class annotated with @Component
or on methods annotated with @Bean
. This annotation can also be applied on constructor arguments or method parameters.
Ex:-
public interface Vehicle {
public void start();
public void stop();
}
There are two beans, Car and Bike implements Vehicle interface
@Component(value="car")
public class Car implements Vehicle {
@Override
public void start() {
System.out.println("Car started");
}
@Override
public void stop() {
System.out.println("Car stopped");
}
}
@Component(value="bike")
public class Bike implements Vehicle {
@Override
public void start() {
System.out.println("Bike started");
}
@Override
public void stop() {
System.out.println("Bike stopped");
}
}
Injecting Bike bean in VehicleService using @Autowired
with @Qualifier
annotation. If you didn't use @Qualifier
, it will throw NoUniqueBeanDefinitionException.
@Component
public class VehicleService {
@Autowired
@Qualifier("bike")
private Vehicle vehicle;
public void service() {
vehicle.start();
vehicle.stop();
}
}
Reference:- @Qualifier annotation example
Install this package in Ubuntu
:
apt install sysv-rc-conf
its a substitute for chkconfig
cmd.
After install run this cmd:
sysv-rc-conf --list
It'll show all services in all the runlevels. You can also run this:
sysv-rc-conf --level (runlevel number ex:1 2 3 4 5 6 )
Now you can choose which service should be active in boot time.
The height is different depending on the browser's window size. It should be set dynamically depending on the size of the browser window

Check out setParseBigDecimal
in DecimalFormat. With this setter, parse
will return a BigDecimal for you.
You probably already know about $(document).ready(...). What you need is a preloading mechanism; something that fetches data (text or images or whatever) before showing it off. This can make a site feel much more professional.
Take a look at jQuery.Preload (there are others). jQuery.Preload has several ways of triggering preloading, and also provides callback functionality (when the image is preloaded, then show it). I have used it heavily, and it works great.
Here's how easy it is to get started with jQuery.Preload:
$(function() {
// First get the preload fetches under way
$.preload(["images/button-background.png", "images/button-highlight.png"]);
// Then do anything else that you would normally do here
doSomeStuff();
});
I had used the WebDeploy IIS Extension to import my websites from IIS6 to IIS7.5, so all of the IIS settings were exactly as they had been in the production environment. After trying all the solutions provided here, none of which worked for me, I simply had to change the App Pool setting for the website from Classic to Integrated.
This line is the problem:
int estimatedPopulation (int currentPopulation,
float growthRate (birthRate, deathRate))
Make it:
int estimatedPopulation (int currentPopulation, float birthRate, float deathRate)
instead and invoke the function with three arguments like
estimatePopulation( currentPopulation, birthRate, deathRate );
OR declare it with two arguments like:
int estimatedPopulation (int currentPopulation, float growthrt ) { ... }
and call it as
estimatedPopulation( currentPopulation, growthRate (birthRate, deathRate));
Probably more important here - C++ (and C) names have scope. You can have two things named the same but not at the same time. In your particular case your grouthRate
variable in the main()
hides the function with the same name. So within main()
you can only access grouthRate
as float
. On the other hand, outside of the main()
you can only access that name as a function, since that automatic variable is only visible within the scope of main()
.
Just hope I didn't confuse you further :)
Expanding from Andriy M, and yes you can do this from a file, even one with multiple lines
@echo off
setlocal EnableExtensions EnableDelayedExpansion
set "INTEXTFILE=test.txt"
set "OUTTEXTFILE=test_out.txt"
set "SEARCHTEXT=bath"
set "REPLACETEXT=hello"
for /f "delims=" %%A in ('type "%INTEXTFILE%"') do (
set "string=%%A"
set "modified=!string:%SEARCHTEXT%=%REPLACETEXT%!"
echo !modified!>>"%OUTTEXTFILE%"
)
del "%INTEXTFILE%"
rename "%OUTTEXTFILE%" "%INTEXTFILE%"
endlocal
EDIT
Thanks David Nelson, I have updated the script so it doesn't have the hard coded values anymore.
Just use notepad ++ with encoding UTF-8 without BOM.
Make sure Blog
has methods equals(Object)
and hashCode()
defined, and addAll(list)
then to a new HashSet()
, or new LinkedHashSet()
if the order is important.
Better yet, use a Set
instead of a List
from the start, since you obviously don't want duplicates, it's better that your data model reflects that rather than having to remove them after the fact.
using (FileStream fs = new FileStream("sample.pdf", FileMode.Open, FileAccess.Read))
{
byte[] bytes = new byte[fs.Length];
int numBytesToRead = (int)fs.Length;
int numBytesRead = 0;
while (numBytesToRead > 0)
{
// Read may return anything from 0 to numBytesToRead.
int n = fs.Read(bytes, numBytesRead, numBytesToRead);
// Break when the end of the file is reached.
if (n == 0)
{
break;
}
numBytesRead += n;
numBytesToRead -= n;
}
numBytesToRead = bytes.Length;
}
Using the below line
SELECT LEFT(subject , 10) FROM tbl
Add inputType to edittext and on enter it will go the next edittext
android:inputType="text"
android:inputType="textEmailAddress"
android:inputType="textPassword"
and many more.
inputType=textMultiLine does not go to the next edittext on enter
Change your crontab command to
* * * * * (cd /home/udi/foo/ || exit 1; ./bar.py)
The (...)
starts a sub-shell that your crond executes as a single command. The || exit 1
causes your cronjob to fail in case that the directory is unavailable.
Though the other solutions may be more elegant in the long run for your specific scripts, my example could still be useful in cases where you can't modify the program or command that you want to execute.
You could compile and link in one command:
gcc file1.c file2.c -o myprogram
And run with:
./myprogram
But to answer the question as asked, simply pass the object files to gcc
:
gcc file1.o file2.o -o myprogram
I was working on this today for a data.frame (really a data.table) with millions of observations and 35 columns. My goal was to return a list of data.frames (data.tables) each with a single row. That is, I wanted to split each row into a separate data.frame and store these in a list.
Here are two methods I came up with that were roughly 3 times faster than split(dat, seq_len(nrow(dat)))
for that data set. Below, I benchmark the three methods on a 7500 row, 5 column data set (iris repeated 50 times).
library(data.table)
library(microbenchmark)
microbenchmark(
split={dat1 <- split(dat, seq_len(nrow(dat)))},
setDF={dat2 <- lapply(seq_len(nrow(dat)),
function(i) setDF(lapply(dat, "[", i)))},
attrDT={dat3 <- lapply(seq_len(nrow(dat)),
function(i) {
tmp <- lapply(dat, "[", i)
attr(tmp, "class") <- c("data.table", "data.frame")
setDF(tmp)
})},
datList = {datL <- lapply(seq_len(nrow(dat)),
function(i) lapply(dat, "[", i))},
times=20
)
This returns
Unit: milliseconds
expr min lq mean median uq max neval
split 861.8126 889.1849 973.5294 943.2288 1041.7206 1250.6150 20
setDF 459.0577 466.3432 511.2656 482.1943 500.6958 750.6635 20
attrDT 399.1999 409.6316 461.6454 422.5436 490.5620 717.6355 20
datList 192.1175 201.9896 241.4726 208.4535 246.4299 411.2097 20
While the differences are not as large as in my previous test, the straight setDF
method is significantly faster at all levels of the distribution of runs with max(setDF) < min(split) and the attr
method is typically more than twice as fast.
A fourth method is the extreme champion, which is a simple nested lapply
, returning a nested list. This method exemplifies the cost of constructing a data.frame from a list. Moreover, all methods I tried with the data.frame
function were roughly an order of magnitude slower than the data.table
techniques.
data
dat <- vector("list", 50)
for(i in 1:50) dat[[i]] <- iris
dat <- setDF(rbindlist(dat))
If you have successfully deleted from workspace tab but still it is showing in drop down menu. Then also you can successfully remove that by following these steps:
user_name will be your username of your computer
There will be two tag
varName = "RecentlyUsedWorkspaces" remove the deleted workspace tag
A propertyList tag will be there with varName=deleted_workspace_name delete that tag.
from drop down menu workspace name will be deleted

Once you have your Context and know the name of the database, use:
context.deleteDatabase(DATABASE_NAME);
When this line gets run, the database should be deleted.
A good trick is to use inner box-shadow, and let it do all the fading for you rather than applying it to the image.

$.each(data, function() {
$.each(this, function(key, val){

MinGW uses a fairly old version of GCC (3.4.5, I believe), and hasn't been updated in a while. If you're already comfortable with the GCC toolset and just looking to get your feet wet in Windows programming, this may be a good option for you. There are lots of great IDEs available that use this compiler.
Edit: Apparently I was wrong; that's what I get for talking about something I know very little about. Tauran points out that there is a project that aims to provide the MinGW toolkit with the current version of GCC. You can download it from their website.
However, I'm not sure that I can recommend it for serious Windows development. If you're not a idealistic fanboy who can't stomach the notion of ever using Microsoft software, I highly recommend investigating Visual Studio, which comes bundled with Microsoft's C/C++ compiler. The Express version (which includes the same compiler as all the paid-for editions) is absolutely free for download. In addition to the compiler, Visual Studio also provides a world-class IDE that makes developing Windows-specific applications much easier. Yes, detractors will ramble on about the fact that it's not fully standards-compliant, but such is the world of writing Windows applications. They're never going to be truly portable once you include windows.h
, so most of the idealistic dedication just ends up being a waste of time.
For folks like me looking at the accepted answer, and not understanding why it's not working, you need to add quotes around your sub directory, in the green checked example,
x_file = open(os.path.join(direct, "5_1.txt"), "r")
should actually be
x_file = open(os.path.join('direct', "5_1.txt"), "r")
You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.
Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.
You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.
You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.
Other answers are great! Few other things which Type
can do but Interface
can't
type Name = string | { FullName: string };
const myName = "Jon"; // works fine
const myFullName: Name = {
FullName: "Jon Doe", //also works fine
};
type Keys = "firstName" | "lastName";
type Name = {
[key in Keys]: string;
};
const myName: Name = {
firstName: "jon",
lastName: "doe",
};
extends
)type Name = {
firstName: string;
lastName: string;
};
type Address = {
city: string;
};
const person: Name & Address = {
firstName: "jon",
lastName: "doe",
city: "scranton",
};
Also not that type
was introduced later as compared to interface
and according to the latest release of TS type
can do *almost everything which interface
can and much more!
*except Declaration merging
(personal opinion: It's good that it's not supported in type as it may lead to inconsistency in code)

The Python dateutil
library is designed for this (and more). It will automatically convert this to a datetime
object for you and raise a ValueError
if it can't.
As an example:
>>> from dateutil.parser import parse
>>> parse("2003-09-25")
datetime.datetime(2003, 9, 25, 0, 0)
This raises a ValueError
if the date is not formatted correctly:
>>> parse("2003-09-251")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/jacinda/envs/dod-backend-dev/lib/python2.7/site-packages/dateutil/parser.py", line 720, in parse
return DEFAULTPARSER.parse(timestr, **kwargs)
File "/Users/jacinda/envs/dod-backend-dev/lib/python2.7/site-packages/dateutil/parser.py", line 317, in parse
ret = default.replace(**repl)
ValueError: day is out of range for month
dateutil
is also extremely useful if you start needing to parse other formats in the future, as it can handle most known formats intelligently and allows you to modify your specification: dateutil
parsing examples.
It also handles timezones if you need that.
Update based on comments: parse
also accepts the keyword argument dayfirst
which controls whether the day or month is expected to come first if a date is ambiguous. This defaults to False. E.g.
>>> parse('11/12/2001')
>>> datetime.datetime(2001, 11, 12, 0, 0) # Nov 12
>>> parse('11/12/2001', dayfirst=True)
>>> datetime.datetime(2001, 12, 11, 0, 0) # Dec 11
The dot "." is a special character in java regex engine, so you have to use "\\." to escape this character:

Hope it helps.
Got same error report.
Fixed with using HTTP instead. Since I don't want set "SSH keys" for a test PC.
Change URL to HTTP when clone:
git clone https://github.com/USERNAME/REPOSITORY.git
My problem is a little bit different: I have URL set when adding a existing local repo to remote, by using:
git remote add origin ssh://github.com/USERNAME/REPOSITORY.git
To fix it, reset URL to HTTP:
git remote set-url origin https://github.com/USERNAME/REPOSITORY.git
BTW, you may check your URL using command:
git remote -v
origin https://github.com/USERNAME/REPOSITORY.git (fetch)
origin https://github.com/USERNAME/REPOSITORY.git (push)
Hope this will help some one like me. :D

The easier and efficient approach is to remove the view from superView and re add as subview again. this causes all the subview constraints get removed automagically.
There is no cross-browser way of styling option elements, certainly not to the extent of your second screenshot. You might be able to make them bold, and set the font-size, but that will be about it...
Make use of Parameter Grouping (Laravel 4.2). For your example, it'd be something like this:
Model::where(function ($query) {
$query->where('a', '=', 1)
->orWhere('b', '=', 1);
})->where(function ($query) {
$query->where('c', '=', 1)
->orWhere('d', '=', 1);
});
To add to the above correct answer :-
For my case in shell, this code worked (working on sqoop

switch is very picky in the sense that the values in the switch must be a compile time constant. and also the value that's being compared must be a primitive (or string now). For this you should use an if statement.
The reason may go back to the way that C handles them in that it creates a jump table (because the values are compile time constants) and it tries to copy the same semantics by not allowing evaluated values in your cases.
Sometimes you need to include mysql db port id in the server like so.
$serverName = "127.0.0.1:3307";
The javadoc for DataSource you refer to is of the wrong package. You should look at javax.sql.DataSource. As you can see this is an interface. The host and port name configuration depends on the implementation, i.e. the JDBC driver you are using.
I have not checked the Derby javadocs but I suppose the code should compile like this:
ClientDataSource ds = org.apache.derby.jdbc.ClientDataSource()
ds.setHost etc....
I was having the same problem while importing the certificate in local keystore. Whenever i issue the keytool command i got the following error.
Certificate was added to keystore keytool error: java.io.FileNotFoundException: C:\Program Files\Java\jdk1.8.0_151\jre\lib\security (Access is denied)
Following solution work for me.
1) make sure you are running command prompt in Rus as Administrator mode
2) Change your current directory to %JAVA_HOME%\jre\lib\security
3) then Issue the below command
keytool -import -alias "mycertificatedemo" -file "C:\Users\name\Downloads\abc.crt" -keystore cacerts
3) give the password changeit
4) enter y
5) you will see the following message on successful "Certificate was added to keystore"
Make sure you are giving the "cacerts" only in -keystore param value , as i was giving the full path like "C**:\Program Files\Java\jdk1.8.0_151\jre\lib\security**".
Hope this will work

Here is a more complete example of an XML filter (the example above by itself will not work since it just shows a snippet and is missing the <FindBugsFilter>
begin and end tags):
<FindBugsFilter>
<Match>

<Method name="bar" />
<Bug pattern="NP_BOOLEAN_RETURN_NULL" />
</Match>
</FindBugsFilter>
If you are using the Android Studio FindBugs plugin, browse to your XML filter file using File->Other Settings->Default Settings->Other Settings->FindBugs-IDEA->Filter->Exclude filter files->Add.
If i remember correctly, you need to use the "Shapes" property of your sheet.
Each Shape object has a TopLeftCell and BottomRightCell attributes that tell you the position of the image.
Here's a piece of code i used a while ago, roughly adapted to your needs. I don't remember the specifics about all those ChartObjects and whatnot, but here it is:
For Each oShape In ActiveSheet.Shapes
strImageName = ActiveSheet.Cells(oShape.TopLeftCell.Row, 1).Value
oShape.Select
'Picture format initialization
Selection.ShapeRange.PictureFormat.Contrast = 0.5: Selection.ShapeRange.PictureFormat.Brightness = 0.5: Selection.ShapeRange.PictureFormat.ColorType = msoPictureAutomatic: Selection.ShapeRange.PictureFormat.TransparentBackground = msoFalse: Selection.ShapeRange.Fill.Visible = msoFalse: Selection.ShapeRange.Line.Visible = msoFalse: Selection.ShapeRange.Rotation = 0#: Selection.ShapeRange.PictureFormat.CropLeft = 0#: Selection.ShapeRange.PictureFormat.CropRight = 0#: Selection.ShapeRange.PictureFormat.CropTop = 0#: Selection.ShapeRange.PictureFormat.CropBottom = 0#: Selection.ShapeRange.ScaleHeight 1#, msoTrue, msoScaleFromTopLeft: Selection.ShapeRange.ScaleWidth 1#, msoTrue, msoScaleFromTopLeft

Set oChartArea = oDia.Chart
oDia.Activate

Use nohup mypythonprog &
, and you can close the terminal window without disrupting the process. You can also run exit
if you are running in the cloud and don't want to leave a hanging shell process.
Save the program with a .pyw
extension and now it will open with pythonw.exe
. No shell window.
For example, if you have foo.py
, you need to rename it to foo.pyw
.
You could also write your own Control for this, in case you want to use this more often. Assuming you have multiple TextBoxes in a Grid, it would look something like this:
public class AdvanceOnEnterTextBox : UserControl
{
TextBox _TextBox;
public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(String), typeof(AdvanceOnEnterTextBox), null);
public static readonly DependencyProperty InputScopeProperty = DependencyProperty.Register("InputScope", typeof(InputScope), typeof(AdvanceOnEnterTextBox), null);
public AdvanceOnEnterTextBox()
{
_TextBox = new TextBox();
_TextBox.KeyDown += customKeyDown;
Content = _TextBox;
}
/// <summary>
/// Text for the TextBox
/// </summary>
public String Text
{
get { return _TextBox.Text; }
set { _TextBox.Text = value; }
}
/// <summary>
/// Inputscope for the Custom Textbox
/// </summary>
public InputScope InputScope
{
get { return _TextBox.InputScope; }
set { _TextBox.InputScope = value; }
}
void customKeyDown(object sender, KeyEventArgs e)
{
if (!e.Key.Equals(Key.Enter)) return;
var element = ((TextBox)sender).Parent as AdvanceOnEnterTextBox;
if (element != null)
{
int currentElementPosition = ((Grid)element.Parent).Children.IndexOf(element);
try
{
// Jump to the next AdvanceOnEnterTextBox (assuming, that Labels are inbetween).
((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition + 2)).Focus();
}
catch (Exception)
{
// Close Keypad if this was the last AdvanceOnEnterTextBox
((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition)).IsEnabled = false;
((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition)).IsEnabled = true;
}
}
}
}
In Swift, using xcode 7 (and later), you can add the following to your AppDelegate.swift file:
UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)
This is the what the complete method looks like:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// I added this line
UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)
return true
}
In the example above my item will be white. The "/255.0" is needed because it expects a value from 0 to 1. For white, I could have just used 1. But for other color you'll probably be using RGB values.
The Visual Studio Build tools are a different download than the IDE. They appear to be a pretty small subset, and they're called Build Tools for Visual Studio 2019 (download).
You can use the GUI to do the installation, or you can script the installation of msbuild:
vs_buildtools.exe --add Microsoft.VisualStudio.Workload.MSBuildTools --quiet
Microsoft.VisualStudio.Workload.MSBuildTools is a "wrapper" ID for the three subcomponents you need:
You can find documentation about the other available CLI switches here.
The build tools installation is much quicker than the full IDE. In my test, it took 5-10 seconds. With --quiet
there is no progress indicator other than a brief cursor change. If the installation was successful, you should be able to see the build tools in %programfiles(x86)%\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin
.
If you don't see them there, try running without --quiet
to see any error messages that may occur during installation.
I found a tool called ttyplot
in homebrew. It's good. https://github.com/tenox7/ttyplot
What about using __proto__
for static methods?
function Foo(name){
this.name = name
Foo.__proto__.collection.push(this)
Foo.__proto__.count++
}
Foo.__proto__.count=0
Foo.__proto__.collection=[]
var bar = new Foo('bar')
var baz = new Foo('baz')
Foo.count;//2
Foo.collection // [{...}, {...}]
bar.count // undefined
NOTE: This will only remove a device configuration from the Xcode devices list. To remove the simulator files from your hard drive see the previous answer.
For Xcode 7 just use Window \ Devices menu in Xcode:
Then select emulator to delete in the list on the left side and right click on it. Here is Delete option:
That's all.
According to the subprocess.check_output()
docs, the exception raised on error has an output
attribute that you can use to access the error details:
try:
subprocess.check_output(...)
except subprocess.CalledProcessError as e:
print(e.output)
You should then be able to analyse this string and parse the error details with the json
module:
if e.output.startswith('error: {'):
error = json.loads(e.output[7:]) # Skip "error: "
print(error['code'])
print(error['message'])
Try this test:
any(substring in string for substring in substring_list)
It will return True
if any of the substrings in substring_list
is contained in string
.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map
directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.
Most of the answers here want you to create a copy of the list. I had a use case where the list was quite long (110K items) and it was smarter to keep reducing the list instead.
First of all you'll need to replace foreach loop with while loop,
i = 0
while i < len(somelist):
if determine(somelist[i]):
del somelist[i]
else:
i += 1
The value of i
is not changed in the if block because you'll want to get value of the new item FROM THE SAME INDEX, once the old item is deleted.
Honestly, I've always been happy with emacs. Then again, I started out using emacs, so I've no doubt that it colours my perceptions. Still, it gives syntax highlighting and formatting, and can easily be configured to build the LaTeX. Check out the TeX mode.
string fileAndPath = @"c:\webserver\public\myCompany\configs\promo.xml";

Add the string you're searching for (CTR
) to the regex like this:
^CTR
Example: regex
That should be enough!
However, if you need to get the text from the whole line in your language of choice, add a "match anything" pattern .*
:
^CTR.*
Example: more regex
If you want to get crazy, use the end of line matcher
$
Add that to the growing regex pattern:
^CTR.*$
Example: lets get crazy
Note: Depending on how and where you're using regex, you might have to use a multi-line modifier to get it to match multiple lines. There could be a whole discussion on the best strategy for picking lines out of a file to process them, and some of the strategies would require this:
Multi-line flag m
(this is specified in various ways in various languages/contexts)
/^CTR.*/gm
Example: we had to use m on regex101
1) You can put your favicon where you want and add this tag to your page head
<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon" />
although some browsers will try to get the favicon from /favicon.ico by default, so you should use the IgnoreRoute.
2) If a browser makes a request for the favicon in another directory it will get a 404 error wich is fine and if you have the link tag in answer 1 in your master page the browser will get the favicon you want.
The user
parameter of your callback is an array with find
. Use findOne
instead of find
when querying for a single instance.
User.findOne({username: oldUsername}, function (err, user) {
user.username = newUser.username;
user.password = newUser.password;
user.rights = newUser.rights;
user.save(function (err) {
if(err) {
console.error('ERROR!');
}
});
});
To convert 2016-02-29 12:24:26 into a date, use this date formatter:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
Edit: To get the output Feb 29, 2016 use this date formatter:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MMM dd, yyyy"
You can try : Yolk
For install yolk, try:
easy_install yolk
Yolk is a Python tool for obtaining information about installed Python packages and querying packages avilable on PyPI (Python Package Index).
You can see which packages are active, non-active or in development mode and show you which have newer versions available by querying PyPI.
Handle should do the trick.
Ever wondered which program has a particular file or directory open? Now you can find out. Handle is a utility that displays information about open handles for any process in the system. You can use it to see the programs that have a file open, or to see the object types and names of all the handles of a program.
I thought I was not stupid enough to mix up the versions - however, I didn't realize that on my new server, a SQL Server 2005 instance was already installed from birth named SQLEXPRESS
. When trying to restore my SQL Server 2008 R2 backed up database in SSMS 2012 to the SQLEXPRESS
instance, the list of backup sets was empty.
Eventually I realized that the SQLEXPRESS
instance on the server was not a 2012 instance, but a 2005. I disconnected and connected to the actual 2012 instance (in my case named SQLEXPRESS2012
), and it (obviously) worked.
I've developed an almost flawless try & catch implementation in bash, that allows you to write code like:
try
echo 'Hello'
false
echo 'This will not be displayed'
catch
echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"
You can even nest the try-catch blocks inside themselves!
try {
echo 'Hello'
try {
echo 'Nested Hello'
false
echo 'This will not execute'
} catch {
echo "Nested Caught (@ $__EXCEPTION_LINE__)"
}
false
echo 'This will not execute too'
} catch {
echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"
}
The code is a part of my bash boilerplate/framework. It further extends the idea of try & catch with things like error handling with backtrace and exceptions (plus some other nice features).
Here's the code that's responsible just for try & catch:
set -o pipefail
shopt -s expand_aliases
declare -ig __oo__insideTryCatch=0
# if try-catch is nested, then set +e before so the parent handler doesn't catch us
alias try="[[ \$__oo__insideTryCatch -gt 0 ]] && set +e;
__oo__insideTryCatch+=1; ( set -e;
trap \"Exception.Capture \${LINENO}; \" ERR;"
alias catch=" ); Exception.Extract \$? || "
Exception.Capture() {
local script="${BASH_SOURCE[1]#./}"
if [[ ! -f /tmp/stored_exception_source ]]; then
echo "$script" > /tmp/stored_exception_source
fi
if [[ ! -f /tmp/stored_exception_line ]]; then
echo "$1" > /tmp/stored_exception_line
fi
return 0
}
Exception.Extract() {
if [[ $__oo__insideTryCatch -gt 1 ]]
then
set -e
fi
__oo__insideTryCatch+=-1
__EXCEPTION_CATCH__=( $(Exception.GetLastException) )
local retVal=$1
if [[ $retVal -gt 0 ]]
then
# BACKWARDS COMPATIBILE WAY:
# export __EXCEPTION_SOURCE__="${__EXCEPTION_CATCH__[(${#__EXCEPTION_CATCH__[@]}-1)]}"
# export __EXCEPTION_LINE__="${__EXCEPTION_CATCH__[(${#__EXCEPTION_CATCH__[@]}-2)]}"
export __EXCEPTION_SOURCE__="${__EXCEPTION_CATCH__[-1]}"
export __EXCEPTION_LINE__="${__EXCEPTION_CATCH__[-2]}"
export __EXCEPTION__="${__EXCEPTION_CATCH__[@]:0:(${#__EXCEPTION_CATCH__[@]} - 2)}"
return 1 # so that we may continue with a "catch"
fi
}
Exception.GetLastException() {
if [[ -f /tmp/stored_exception ]] && [[ -f /tmp/stored_exception_line ]] && [[ -f /tmp/stored_exception_source ]]
then
cat /tmp/stored_exception
cat /tmp/stored_exception_line
cat /tmp/stored_exception_source
else
echo -e " \n${BASH_LINENO[1]}\n${BASH_SOURCE[2]#./}"
fi
rm -f /tmp/stored_exception /tmp/stored_exception_line /tmp/stored_exception_source
return 0
}

One is a column (aka Series), while the other is a DataFrame:
In [1]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])
In [2]: df
Out[2]:
a b
0 1 2
1 3 4
The column 'b' (aka Series):
In [3]: df['b']
Out[3]:
0 2
1 4
Name: b, dtype: int64
The subdataframe with columns (position) in [1]:
In [4]: df[[1]]
Out[4]:
b
0 2
1 4
Note: it's preferable (and less ambiguous) to specify whether you're talking about the column name e.g. ['b'] or the integer location, since sometimes you can have columns named as integers:
In [5]: df.iloc[:, [1]]
Out[5]:
b
0 2
1 4
In [6]: df.loc[:, ['b']]
Out[6]:
b
0 2
1 4
In [7]: df.loc[:, 'b']
Out[7]:
0 2
1 4
Name: b, dtype: int64
You can simply use Query Builder rather than Eloquent, this code directly update your data in the database :) This is a sample:
DB::table('post')
->where('id', 3)
->update(['title' => "Updated Title"]);
You can check the documentation here for more information: http://laravel.com/docs/5.0/queries#updates
If you want to apply it as a commit, use git am.
If you are interested in understand performance, the best answer is to use a profiler.
Otherwise, System.Diagnostics.StopWatch provides a high resolution timer.
You need to use ListBox.ItemContainerStyle.
ListBox.ItemTemplate specifies how the content of an item should be displayed. But WPF still wraps each item in a ListBoxItem control, which by default gets its Background set to the system highlight colour if it is selected. You can't stop WPF creating the ListBoxItem controls, but you can style them -- in your case, to set the Background to always be Transparent or Black or whatever -- and to do so, you use ItemContainerStyle.
juFo's answer shows one possible implementation, by "hijacking" the system background brush resource within the context of the item style; another, perhaps more idiomatic technique is to use a Setter
for the Background property.

As basZero mentioned, X-Forwarded-For should be checked for comma. (Look at : http://en.wikipedia.org/wiki/X-Forwarded-For). The general format of the field is: X-Forwarded-For: clientIP, proxy1, proxy2... and so on. So we will be seeing something like this : X-FORWARDED-FOR: 129.77.168.62, 129.77.63.62.
Normally a jdk installation has javac in the environment path variables ... so if you check for javac in the path, that's pretty much a good indicator that you have a jdk installed.
I have to add an important comment. Everyone is mentioning that NOLOCK
reads only dirty data. This is not precise. It is also possible that you'll get same row twice or whole row is skipped during your read. Reason is that you could ask for some data in same time when SQL Server is re-balancing b-tree.
Check another threads
https://stackoverflow.com/a/5469238/2108874
http://www.sqlmag.com/article/sql-server/quaere-verum-clustered-index-scans-part-iii.aspx)
With the NOLOCK hint (or setting the isolation level of the session to READ UNCOMMITTED) you tell SQL Server that you don't expect consistency, so there are no guarantees. Bear in mind though that "inconsistent data" does not only mean that you might see uncommitted changes that were later rolled back, or data changes in an intermediate state of the transaction. It also means that in a simple query that scans all table/index data SQL Server may lose the scan position, or you might end up getting the same row twice.

<a href="http://yahoo.com">This will only display if $condition is true</a>
<?php elseif($anotherCondition) : ?>

It's that simple.
The HTML will only be displayed if the condition is satisfied.

localhost and 127.0.0.1 are both ways of saying 'the current machine'. So localhost on your PC is the PC and localhost on the android is the phone. Since your phone isn't running a webserver of course it will refuse the connection.
You need to get the IP address of your machine (use ipconfig on windows to find out) and use that instead of 127.0.0.1. This may still not working depending on how your network/firewalls are set up. But that is a completely different topic.
The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr)
instead of 1fr
as your track size.
Just select from the Visual Studio menu View- > ToolBox .
You can also define an environment variable (new feature in 2010 - i.e. python 2.7)
export PYTHONWARNINGS="ignore"
Test like this: Default
$ export PYTHONWARNINGS="default"
$ python
>>> import warnings
>>> warnings.warn('my warning')
__main__:1: UserWarning: my warning
>>>
Ignore warnings
$ export PYTHONWARNINGS="ignore"
$ python
>>> import warnings
>>> warnings.warn('my warning')

For deprecation warnings have a look at how-to-ignore-deprecation-warnings-in-python
Copied here...
From documentation of the warnings
module:
#!/usr/bin/env python -W ignore::DeprecationWarning
If you're on Windows: pass -W ignore::DeprecationWarning
as an argument to Python. Better though to resolve the issue, by casting to int.
(Note that in Python 3.2, deprecation warnings are ignored by default.)
Or:
import warnings
with warnings.catch_warnings():
warnings.filterwarnings("ignore", category=DeprecationWarning)
import md5, sha
yourcode()
Now you still get all the other DeprecationWarning
s, but not the ones caused by:
import md5, sha
Always prefer to use the language features over some additional tools like preprocessor.
ES.31: Don't use macros for constants or "functions"
Macros are a major source of bugs. Macros don't obey the usual scope and type rules. Macros don't obey the usual rules for argument passing. Macros ensure that the human reader sees something different from what the compiler sees. Macros complicate tool building.
From C++ Core Guidelines
if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):
count before dedupe:
df.count()
do the de-dupe (convert the column you are de-duping to string type):
from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))
df.drop_duplicates(subset=['colName']).count()
can use a sorted groupby to check to see that duplicates have been removed:
df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)
I had the same problem when my plugin was depending on another project, which exported some packages in its manifest file. Instead of changing access rules, I have managed to solve the problem by adding the required packages into its Export-Package section. This makes the packages legally visible. Eclipse actually provides this fix on the "Access restriction" error marker.
In Jest you have to pass a function into expect(function).toThrow(<blank or type of error>)
.
Example:
test("Test description", () => {
const t = () => {
throw new TypeError();
};
expect(t).toThrow(TypeError);
});
Or if you also want to check for error message:
test("Test description", () => {
const t = () => {
throw new TypeError("UNKNOWN ERROR");
};
expect(t).toThrow(TypeError);
expect(t).toThrow("UNKNOWN ERROR");
});
If you need to test an existing function whether it throws with a set of arguments, you have to wrap it inside an anonymous function in expect()
.
Example:
test("Test description", () => {
expect(() => {http.get(yourUrl, yourCallbackFn)}).toThrow(TypeError);
});
When not told otherwise commands take over the foreground. You only have one "foreground" process running in a single shell session. The & symbol instructs commands to run in a background process and immediately returns to the command line for additional commands.
sh my_script.sh &
A background process will not stay alive after the shell session is closed. SIGHUP terminates all running processes. By default anyway. If your command is long-running or runs indefinitely (ie: microservice) you need to pr-pend it with nohup so it remains running after you disconnect from the session:
nohup sh my_script.sh &
EDIT: There does appear to be a gray area regarding the closing of background processes when & is used. Just be aware that the shell may close your process depending on your OS and local configurations (particularly on CENTOS/RHEL): https://serverfault.com/a/117157.
You can use the MAX aggregate, it would still work. MAX of one value = that value..
In this case, you could also self join 5 times on customerid, filter by dbColumnName per table reference. It may work out better.
After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.
It's incorrect to use zeros in date or in datetime, just put null instead of zeros.
Thanks @BIJAY_JHA and @Manaus. I used the Kotlin version to call my signIn() method that lives in the Activity and that I'm calling from a Fragment. I'm using Navigation Architecture in Android so the Listener interface pattern isn't in the Fragment:

sys.path
is only searched for Python modules. For dynamic linked libraries, the paths searched must be in LD_LIBRARY_PATH
. Check if your LD_LIBRARY_PATH
includes /usr/local/lib
, and if it doesn't, add it and try again.
Some more information (source):
In Linux, the environment variable LD_LIBRARY_PATH is a colon-separated set of directories where libraries should be searched for first, before the standard set of directories; this is useful when debugging a new library or using a nonstandard library for special purposes. The environment variable LD_PRELOAD lists shared libraries with functions that override the standard set, just as /etc/ld.so.preload does. These are implemented by the loader /lib/ld-linux.so. I should note that, while LD_LIBRARY_PATH works on many Unix-like systems, it doesn't work on all; for example, this functionality is available on HP-UX but as the environment variable SHLIB_PATH, and on AIX this functionality is through the variable LIBPATH (with the same syntax, a colon-separated list).
Update: to set LD_LIBRARY_PATH
, use one of the following, ideally in your ~/.bashrc
or equivalent file:
export LD_LIBRARY_PATH=/usr/local/lib
or
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
Use the first form if it's empty (equivalent to the empty string, or not present at all), and the second form if it isn't. Note the use of export.
For the less specific case (not just the code in the question - since this is one of the first results in Google for this generic error message. This error also occurs when running certain os command with None argument.
For example:
os.path.exists(arg)
os.stat(arg)
Will raise this exception when arg is None.
Try -
var monthNames = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
var newDate = new Date(form.startDate.value);
var formattedDate = monthNames[newDate.getMonth()] + ' ' + newDate.getFullYear();
You're offsetting the shadow, so to get it to uniformly surround the box, don't offset it:

Solution for Android Q:

To get the current router instance or current location you have to create a Higher order component with withRouter
from react-router-dom
. otherwise, when you are trying to access this.props.location
it will return undefined
Example
import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';
class className extends Component {
render(){
return(
....
)
}
}
export default withRouter(className)
If you really want to use single quotes in the outermost layer, remember that you can glue both kinds of quotation. Example:
alias rxvt='urxvt -fg '"'"'#111111'"'"' -bg '"'"'#111111'"'"
# ^^^^^ ^^^^^ ^^^^^ ^^^^
# 12345 12345 12345 1234
Explanation of how '"'"'
is interpreted as just '
:
'
End first quotation which uses single quotes."
Start second quotation, using double-quotes.'
Quoted character."
End second quotation, using double-quotes.'
Start third quotation, using single quotes.If you do not place any whitespaces between (1) and (2), or between (4) and (5), the shell will interpret that string as a one long word.
This is not "auto-completion", this is automation. One common tool for these things is called Expect.
You might also get away with just piping input from yes
.
For people just stumbling upon this now, I resolved an error of this type that was thrown with all the references and using statements placed properly. There's evidently some confusion with substituting in a function that returns DataTable instead of calling it on a declared DataTable. For example:
This worked for me:
DataTable dt = SomeObject.ReturnsDataTable();
List<string> ls = dt.AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();
But this didn't:
List<string> ls = SomeObject.ReturnsDataTable().AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();
I'm still not 100% sure why, but if anyone is frustrated by an error of this type, give this a try.
You can use readAllLines and the join
method to get whole file content in one line:
String str = String.join("\n",Files.readAllLines(Paths.get("e:\\text.txt")));
It uses UTF-8 encoding by default, which reads ASCII data correctly.
Also you can use readAllBytes:
String str = new String(Files.readAllBytes(Paths.get("e:\\text.txt")), StandardCharsets.UTF_8);
I think readAllBytes is faster and more precise, because it does not replace new line with \n
and also new line may be \r\n
. It is depending on your needs which one is suitable.
In general, it's not safe, though for some collections it may be. The obvious alternative is to use some kind of for loop. But you didn't say what collection you're using, so that may or may not be possible.
BinaryFormatter
may produce invalid output in some specific cases. For example it will omit unpaired surrogate characters. It may also have problems with values of interface types. Read this documentation page including community content.
If you find your error to be persistent you may want to consider using XML serializer like DataContractSerializer
or XmlSerializer
.
git checkout filename
git reset --hard
might do the trick as well

With EF or LINQ to SQL:
var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();
With LINQ to Objects I suggest to use morelinq extension MaxBy
(get morelinq from nuget):
var item = items.MaxBy(i => i.Value);
If you get 'Access violation at address 00000000.', you are calling a function pointer that hasn't been assigned - possibly an event handler or a callback function.
for example
type
TTest = class(TForm);
protected
procedure DoCustomEvent;
public
property OnCustomEvent : TNotifyEvent read FOnCustomEvent write FOnCustomEvent;
end;
procedure TTest.DoCustomEvent;
begin
FOnCustomEvent(Self);
end;
Instead of
procedure TTest.DoCustomEvent;
begin
if Assigned(FOnCustomEvent) then // need to check event handler is assigned!
FOnCustomEvent(Self);
end;
If the error is in a third party component, and you can track the offending code down, use an empty event handler to prevent the AV.

Try looking here: Best way to get application folder path
To quote from there:
System.IO.Directory.GetCurrentDirectory()
returns the current directory, which may or may not be the folder where the application is located. The same goes for Environment.CurrentDirectory. In case you are using this in a DLL file, it will return the path of where the process is running (this is especially true in ASP.NET).
This is default database :
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'mydatabase',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
Add another database at the bottom of database.php file
$db['second'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'mysecond',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
In autoload.php config file
$autoload['libraries'] = array('database', 'email', 'session');
The default database is worked fine by autoload the database library but second database load and connect by using constructor in model and controller...
<?php
class Seconddb_model extends CI_Model {
function __construct(){
parent::__construct();
//load our second db and put in $db2
$this->db2 = $this->load->database('second', TRUE);
}
public function getsecondUsers(){
$query = $this->db2->get('members');
return $query->result();
}
}
?>
I think there is an unwritten rule (something like a convention) that says to use 'alias' just for registering a method-name alias, means if you like to give the user of your code one method with more than one name:
class Engine
def start
#code goes here
end
alias run start
end
If you need to extend your code, use the ruby meta alternative.
class Engine
def start
puts "start me"
end
end
Engine.new.start() # => start me
Engine.class_eval do
unless method_defined?(:run)
alias_method :run, :start
define_method(:start) do
puts "'before' extension"
run()
puts "'after' extension"
end
end
end
Engine.new.start
# => 'before' extension
# => start me
# => 'after' extension
Engine.new.run # => start me
If you specify @GET("foobar?a=5")
, then any @Query("b")
must be appended using &
, producing something like foobar?a=5&b=7
.
If you specify @GET("foobar")
, then the first @Query
must be appended using ?
, producing something like foobar?b=7
.
That's how Retrofit works.
When you specify @GET("foobar?")
, Retrofit thinks you already gave some query parameter, and appends more query parameters using &
.
Remove the ?
, and you will get the desired result.
I had a very similar issue with the same error message. "Changes not staged for commit", yet when I do a diff it shows differences. I finally figured out that a while back I had changed a directories case. ex. "PostgeSQL" to "postgresql". As I remember now sometimes git will leave a file or two behind in the old case directory. Then you will commit a new version to the new case.
Thus git doesn't know which one to rely on. So to resolve it, I had to go onto the github's website. Then you're able to view both cases. And you must delete all the files in the incorrect cased directory. Be sure that you have the correct version saved off or in the correct cased directory.
Once you have deleted all the files in the old case directory, that whole directory will disappear. Then do a commit.
At this point you should be able to do a Pull on your local computer and not see the conflicts any more. Thus being able to commit again. :)
You can use Javascript URLSearchParams.
var url = new URL(window.location.href);
url.searchParams.set('single','');
window.location.href = url.href;
[UPDATE]: If IE support is a need, check this thread:
SCRIPT5009: 'URLSearchParams' is undefined in IE 11
Thanks @john-m to talk about the IE support
For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.
Do NOT do this:
git branch -t newbranch
git reset --hard HEAD~3
git checkout newbranch
As the next time you run git rebase
(or git pull --rebase
) those 3 commits would be silently discarded from newbranch
! (see explanation below)
Instead do this:
git reset --keep HEAD~3
git checkout -t -b newbranch
git cherry-pick ..HEAD@{2}
--keep
is like --hard
, but safer, as fails rather than throw away uncommitted changes).newbranch
.newbranch
. Since they're no longer referenced by a branch, it does that by using git's reflog: HEAD@{2}
is the commit that HEAD
used to refer to 2 operations ago, i.e. before we 1. checked out newbranch
and 2. used git reset
to discard the 3 commits.Warning: the reflog is enabled by default, but if you've manually disabled it (e.g. by using a "bare" git repository), you won't be able to get the 3 commits back after running git reset --keep HEAD~3
.
An alternative that doesn't rely on the reflog is:
# newbranch will omit the 3 most recent commits.
git checkout -b newbranch HEAD~3
git branch --set-upstream-to=oldbranch
# Cherry-picks the extra commits from oldbranch.
git cherry-pick ..oldbranch
# Discards the 3 most recent commits from oldbranch.
git branch --force oldbranch oldbranch~3
(if you prefer you can write @{-1}
- the previously checked out branch - instead of oldbranch
).
Why would git rebase
discard the 3 commits after the first example? It's because git rebase
with no arguments enables the --fork-point
option by default, which uses the local reflog to try to be robust against the upstream branch being force-pushed.
Suppose you branched off origin/master when it contained commits M1, M2, M3, then made three commits yourself:
M1--M2--M3 <-- origin/master
\
T1--T2--T3 <-- topic
but then someone rewrites history by force-pushing origin/master to remove M2:
M1--M3' <-- origin/master
\
M2--M3--T1--T2--T3 <-- topic
Using your local reflog, git rebase
can see that you forked from an earlier incarnation of the origin/master branch, and hence that the M2 and M3 commits are not really part of your topic branch. Hence it reasonably assumes that since M2 was removed from the upstream branch, you no longer want it in your topic branch either once the topic branch is rebased:
M1--M3' <-- origin/master
\
T1'--T2'--T3' <-- topic (rebased)
This behavior makes sense, and is generally the right thing to do when rebasing.
So the reason that the following commands fail:
git branch -t newbranch
git reset --hard HEAD~3
git checkout newbranch
is because they leave the reflog in the wrong state. Git sees newbranch
as having forked off the upstream branch at a revision that includes the 3 commits, then the reset --hard
rewrites the upstream's history to remove the commits, and so next time you run git rebase
it discards them like any other commit that has been removed from the upstream.
But in this particular case we want those 3 commits to be considered as part of the topic branch. To achieve that, we need to fork off the upstream at the earlier revision that doesn't include the 3 commits. That's what my suggested solutions do, hence they both leave the reflog in the correct state.
For more details, see the definition of --fork-point
in the git rebase and git merge-base docs.
Path.GetFullPath(@"c:\windows\temp\..\system32")?
For at DataFrame one can simply type
head(data, num=10L)
to get the first 10 for example.
For a data.frame one can simply type
head(data, 10)
to get the first 10.
I want to give a more generalized answer. One that will handle any case when you want to select only the first item in a LEFT JOIN.
You can use a subquery that GROUP_CONCATS what you want (sorted, too!), then just split the GROUP_CONCAT'd result and take only its first item, like so...
LEFT JOIN Person ON Person.id = (
SELECT SUBSTRING_INDEX(
GROUP_CONCAT(FirstName ORDER BY FirstName DESC SEPARATOR "_" ), '_', 1)
) FROM Person
);
Since we have DESC as our ORDER BY option, this will return a Person id for someone like "Zack". If we wanted someone with the name like "Andy", we would change ORDER BY FirstName DESC to ORDER BY FirstName ASC.
This is nimble, as this places the power of ordering totally within your hands. But, after much testing, it will not scale well in a situation with lots of users and lots of data.
It is, however, useful in running data-intensive reports for admin.
there should has a concurrent implemention of List interface supporting such operation.
try java.util.concurrent.CopyOnWriteArrayList.class
You should use Array.prototype.reduce to do this. I did do a little JS perf test to verify that this is more performant than doing a .filter
+ .map
.
$scope.appIds = $scope.applicationsHere.reduce(function(ids, obj){
if(obj.selected === true){
ids.push(obj.id);
}
return ids;
}, []);
Just for the sake of clarity, here's the sample .reduce
I used in the JSPerf test:
var things = [_x000D_
{id: 1, selected: true},_x000D_
{id: 2, selected: true},_x000D_
{id: 3, selected: true},_x000D_
{id: 4, selected: true},_x000D_
{id: 5, selected: false},_x000D_
{id: 6, selected: true},_x000D_
{id: 7, selected: false},_x000D_
{id: 8, selected: true},_x000D_
{id: 9, selected: false},_x000D_
{id: 10, selected: true},_x000D_
];_x000D_
_x000D_
_x000D_
var ids = things.reduce((ids, thing) => {_x000D_
if (thing.selected) {_x000D_
ids.push(thing.id);_x000D_
}_x000D_
return ids;_x000D_
}, []);_x000D_
_x000D_
console.log(ids)
_x000D_
EDIT 1
Note, As of 2/2018 Reduce + Push is fastest in Chrome and Edge, but slower than Filter + Map in Firefox
In jQuery you can do like this.

I use javadoc packaged by Allimant since I was in college.

The javadoc is in the CHM format (standard windows help format), so it's the best viewed when you're using windows.
It means that a Lambda expression of type TDelegate

Simplify your query. The one you provided can be rewritten as the following and will compile:
Arr[] myArray = objects.Select(o => new Obj()
{
Var1 = o.someVar,
Var2 = o.var2
} ).ToArray();
You now can do this with Flexbox justify-content: flex-end
now:
div {_x000D_
display: flex;_x000D_
justify-content: flex-end;_x000D_
align-items: flex-end;_x000D_
width: 150px;_x000D_
height: 150px;_x000D_
border: solid 1px red;_x000D_
}_x000D_
_x000D_
<div>_x000D_
Something to align_x000D_
</div>
_x000D_
Consult your Caniuse to see if Flexbox is right for you.
Initialization error occurred. There is not enough memory or disk space, or you entered an invalid drive name or invalid syntax on the command line.
So basically it could be just about anything haha...try running the command one at a time from the command prompt to figure out which part of which command is giving you trouble.
This means the port is used somewhere else. so, you need to try another one or stop using the old port.

Guava 15 has now added a set of straightforward URL escapers.
This gets asked a lot. Basically, no there isn't, not for .NET 4.0. You have to do it manually at the start of each new thread (or ThreadPool
function). You could perhaps store the culture name (or just the culture object) in a static field to save having to hit the DB, but that's about it.
All of the Func delegates take at least one parameter
That's not true. They all take at least one type argument, but that argument determines the return type.
So Func<T>
accepts no parameters and returns a value. Use Action
or Action<T>
when you don't want to return a value.
I wrote some classes for parsing HTML tags in C#. They are nice and simple if they meet your particular needs.
You can read an article about them and download the source code at http://www.blackbeltcoder.com/Articles/strings/parsing-html-tags-in-c.
There's also an article about a generic parsing helper class at http://www.blackbeltcoder.com/Articles/strings/a-text-parsing-helper-class.
Check df -h if you are under centOS system
You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question. The print statement is probably the most crucial piece of information. The second most crucial piece of information is the error, which you also did not include. Next time, include both of those.
print $ids
should be a fairly hard statement to mess up, but it is possible. Possible reasons:
$ids
is undefined. Gives the warning undefined value in print
$ids
is out of scope. With use
strict
, gives fatal warning Global
variable $ids needs explicit package
name
, and otherwise the undefined
warning from above.print $ids $nIds
,
in which case perl thinks that $ids
is supposed to be a filehandle, and
you get an error such as print to
unopened filehandle
.Explanations
1: Should not happen. It might happen if you do something like this (assuming you are not using strict
):
my $var;
while (<>) {
$Var .= $_;
}
print $var;
Gives the warning for undefined value, because $Var
and $var
are two different variables.
2: Might happen, if you do something like this:
if ($something) {
my $var = "something happened!";
}
print $var;
my
declares the variable inside the current block. Outside the block, it is out of scope.
3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings
.
4: Also a common mistake. There are a number of ways to correctly print two variables in the same print
statement:
print "$var1 $var2"; # concatenation inside a double quoted string
print $var1 . $var2; # concatenation
print $var1, $var2; # supplying print with a list of args
Lastly, some perl magic tips for you:
use strict;
use warnings;
# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;
# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;
my $ids = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";
Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.
Variations:
print "@file"
is equivalent to
$ids = join(' ',@file); print $ids;
$#file
will return the last index
in @file
. Since arrays usually start at 0,
$#file + 1
is equivalent to scalar @file
. You can also do:
my $ids;
do {
local $/;
$ids = <$fh>;
}
By temporarily "turning off" $/
, the input record separator, i.e. newline, you will make <$fh>
return the entire file. What <$fh>
really does is read until it finds $/
, then return that string. Note that this will preserve the newlines in $ids
.
Line-by-line solution:
open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
chomp;
$ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.
You might find it very useful to sample Redis keys and group them by type. Salvatore has written a tool called redis-sampler that issues about 10000 RANDOMKEY
commands followed by a TYPE
on retrieved keys. In a matter of seconds, or minutes, you should get a fairly accurate view of the distribution of key types.
I've written an extension (unfortunately not anywhere open-source because it's work related), that adds a bit of introspection of key names via regexs that give you an idea of what kinds of application keys (according to whatever naming structure you're using), are stored in Redis. Combined with the more general output of redis-sampler, this should give you an extremely good idea of what's going on.
One annoying aspect with LISTAGG
is that if the total length of concatenated string exceeds 4000 characters( limit for VARCHAR2
in SQL ), the below error is thrown, which is difficult to manage in Oracle versions upto 12.1
ORA-01489: result of string concatenation is too long
A new feature added in 12cR2 is the ON OVERFLOW
clause of LISTAGG
.
The query including this clause would look like:
SELECT pid, LISTAGG(Desc, ' ' on overflow truncate) WITHIN GROUP (ORDER BY seq) AS desc
FROM B GROUP BY pid;
The above will restrict the output to 4000 characters but will not throw the ORA-01489
error.
These are some of the additional options of ON OVERFLOW
clause:
ON OVERFLOW TRUNCATE 'Contd..'
: This will display 'Contd..'
at
the end of string (Default is ...
)ON OVERFLOW TRUNCATE ''
: This will display the 4000 characters
without any terminating string.ON OVERFLOW TRUNCATE WITH COUNT
: This will display the total
number of characters at the end after the terminating characters.
Eg:- '...(5512)
'ON OVERFLOW ERROR
: If you expect the LISTAGG
to fail with the
ORA-01489
error ( Which is default anyway ).Use JpaRepository
or CrudRepository
as repository interface:
@Repository
public interface CustomerRepository extends JpaRepository<Customer, Integer> {
@Query("SELECT t from Customer t where LOWER(t.name) LIKE %:name%")
public List<Customer> findByName(@Param("name") String name);
}
@Service(value="customerService")
public class CustomerServiceImpl implements CustomerService {
private CustomerRepository customerRepository;
//...
@Override
public List<Customer> pattern(String text) throws Exception {
return customerRepository.findByName(text.toLowerCase());
}
}
There's a nice article with code on this topic on MSDN. I'm assuming that setting the Style property to ProgressBarStyle.Marquee is not appropriate (or is that what you are trying to control?? -- I don't think it is possible to stop/start this animation although you can control the speed as @Paul indicates).
I have not used pyserial but based on the API documentation at https://pyserial.readthedocs.io/en/latest/shortintro.html it seems like a very nice interface. It might be worth double-checking the specification for AT commands of the device/radio/whatever you are dealing with.
Specifically, some require some period of silence before and/or after the AT command for it to enter into command mode. I have encountered some which do not like reads of the response without some delay first.
You can simply use std::bind
with a your destroy function.
std::unique_ptr<Bar, std::function<void(Bar*)>> bar(create(), std::bind(&destroy,
std::placeholders::_1));
But of course you can also use a lambda.
std::unique_ptr<Bar, std::function<void(Bar*)>> ptr(create(), [](Bar* b){ destroy(b);});

You can use the Range object in VBA to set the value of a named cell, just like any other cell.
Range("C1").Value = Inputbox("Which job number would you like to add to the list?)
Where "C1" is the name of the cell you want to update.
My Excel VBA is a little bit old and crusty, so there may be a better way to do this in newer versions of Excel.
Yet another
public static string ReplaceAtPosition(this string self, int position, string newValue)
{
return self.Remove(position, newValue.Length).Insert(position, newValue);
}
Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup
$("#div").html($("#input").val());
If speed is critical, you might want to look for the Aho-Corasick algorithm for sets of patterns.
It's a trie with failure links, that is, complexity is O(n+m+k), where n is the length of the input text, m the cumulative length of the patterns and k the number of matches. You just have to modify the algorithm to terminate after the first match is found.

You can use it like this:
thread_pool pool(2);
pool.enqueue([] {
std::cout << "Hello from Task 1\n";
});
pool.enqueue([] {
std::cout << "Hello from Task 2\n";
});
Keep in mind that reinventing an efficient asynchronous queuing mechanism is not trivial.
Boost::asio::io_service is a very efficient implementation, or actually is a collection of platform-specific wrappers (e.g. it wraps I/O completion ports on Windows).
You're looking for itertools.compress

Don't use filter
as a variable name, it is a built-in function.
I've generalized this into a Jquery plugin which takes a regex as an argument.
Coffee:
$.fn.removeClassRegex = (regex) ->
$(@).removeClass (index, classes) ->
classes.split(/\s+/).filter (c) ->
regex.test c
.join ' '
Javascript:
$.fn.removeClassRegex = function(regex) {
return $(this).removeClass(function(index, classes) {
return classes.split(/\s+/).filter(function(c) {
return regex.test(c);
}).join(' ');
});
};
So, for this case, usage would be (both Coffee and Javascript):
$('#hello').removeClassRegex(/^color-/)
Note that I'm using the Array.filter
function which doesn't exist in IE<9. You could use Underscore's filter function instead or Google for a polyfill like this WTFPL one.

Create a file inside /etc/nginx/sites-available
and call it whatever you want, I'll call it django
since it's a djanog server
sudo touch /etc/nginx/sites-available/django
Then create a symlink that points to it
sudo ln -s /etc/nginx/sites-available/django /etc/nginx/sites-enabled
Then edit that file with whatever file editor you use, vim
or nano
or whatever and create the server inside it
server {
# hostname or ip or multiple separated by spaces
server_name localhost example.com 192.168.1.1; #change to your setting
location / {
root /home/techcee/scrapbook/local/lib/python2.7/site-packages/django/__init__.pyc/;
}
}
Restart or reload nginx settings
sudo service nginx reload
Note I believe that your configuration like this probably won't work yet because you need to pass it to a fastcgi server or something, but at least this is how you could create a valid server
This is all awkward and not local settings independent. Do it like this:
%CYGWIN_DIR%\bin\date +%%Y%%m%%d_%%H%%M% > date.txt
for /f "delims=" %%a in ('type "date.txt" 2^>NUL') do set datetime=%%a
echo %datetime%
del date.txt
Yes, use Cygwin date and all your problems are gone!
If using a StackTraceElement, use:
String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);
System.out.println(simpleClassName);
function removeParam(parameter)
{
var url=document.location.href;
var urlparts= url.split('?');
if (urlparts.length>=2)
{
var urlBase=urlparts.shift();
var queryString=urlparts.join("?");
var prefix = encodeURIComponent(parameter)+'=';
var pars = queryString.split(/[&;]/g);
for (var i= pars.length; i-->0;)
if (pars[i].lastIndexOf(prefix, 0)!==-1)
pars.splice(i, 1);
url = urlBase+'?'+pars.join('&');
window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .
}
return url;
}
This will resolve your problem
From the man page:
-i When a script is passed as first argument or the -c option is used, enter interactive mode after executing the script or the command. It does not read the $PYTHONSTARTUP file. This can be useful to inspect global variables or a stack trace when a script raises an exception.
So this should do what you want:
python -i file.py
I can't understand why this JAXB IllegalAnnotationException is thrown
I also was getting the ### counts of IllegalAnnotationExceptions
exception and it seemed to be due to an improper dependency hierarchy in my Spring wiring.
I figured it out by putting a breakpoint in the JAXB code when it does the throw. For me this was at com.sun.xml.bind.v2.runtime.IllegalAnnotationsException$Builder.check()
. Then I dumped the list
variable which gives something like:
[org.mortbay.jetty.Handler is an interface, and JAXB can't handle interfaces.
this problem is related to the following location:
at org.mortbay.jetty.Handler
at public org.mortbay.jetty.Handler[] org.mortbay.jetty.handler.HandlerCollection.getHandlers()
at org.mortbay.jetty.handler.HandlerCollection
at org.mortbay.jetty.handler.ContextHandlerCollection
at com.mprew.ec2.commons.server.LocalContextHandlerCollection
at private com.mprew.ec2.commons.server.LocalContextHandlerCollection com.mprew.ec2.commons.services.jaxws_asm.SetLocalContextHandlerCollection.arg0
at com.mprew.ec2.commons.services.jaxws_asm.SetLocalContextHandlerCollection,
org.mortbay.jetty.Handler does not have a no-arg default constructor.]
....
The does not have a no-arg default constructor
seemed to me to be misleading. Maybe I wasn't understanding what the exception was saying. But it did indicate that there was a problem with my LocalContextHandlerCollection
. I removed a dependency loop and the error cleared.
Hopefully this will be helpful to others.
Here I present an alternative way to detect a browser, based on feature availability.
To detect only IE, you can use this:
if(/*@cc_on!@*/false || typeof ScriptEngineMajorVersion === "function")
{
//You are using IE>=4 (unreliable for IE11)
}
else
{
//You are using other browser
}
To detect the most popular browsers:
if(/*@cc_on!@*/false || typeof ScriptEngineMajorVersion === "function")
{
//You are using IE >= 4 (unreliable for IE11!!!)
}
else if(window.chrome)
{
//You are using Chrome or Chromium
}
else if(window.opera)
{
//You are using Opera >= 9.2
}
else if('MozBoxSizing' in document.body.style)
{
//You are using Firefox or Firefox based >= 3.2
}
else if({}.toString.call(window.HTMLElement).indexOf('Constructor')+1)
{
//You are using Safari >= 3.1
}
else
{
//Unknown
}
This answer was updated because IE11 no longer supports conditional compilation (the /*@cc_on!@*/false
trick).
You can check Did IE11 remove javascript conditional compilation? for more informations regarding this topic.
I've used the suggestion they presented there.
Alternatively, you can use typeof document.body.style.msTransform == "string"
or document.body.style.msTransform !== window.undefined
or even 'msTransform' in document.body.style
.
How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it?
I posted a gist that solves this question/problem with a decorator and a threading.Timer
. Here it is with a breakdown.
It was tested with Python 2 and 3. It should also work under Unix/Linux and Windows.
First the imports. These attempt to keep the code consistent regardless of the Python version:
from __future__ import print_function
import sys
import threading
from time import sleep
try:
import thread
except ImportError:
import _thread as thread
Use version independent code:
try:
range, _print = xrange, print
def print(*args, **kwargs):
flush = kwargs.pop('flush', False)
_print(*args, **kwargs)
if flush:
kwargs.get('file', sys.stdout).flush()
except NameError:
pass
Now we have imported our functionality from the standard library.
exit_after
decoratorNext we need a function to terminate the main()
from the child thread:
def quit_function(fn_name):
# print to stderr, unbuffered in Python 2.
print('{0} took too long'.format(fn_name), file=sys.stderr)
sys.stderr.flush() # Python 3 stderr is likely buffered.
thread.interrupt_main() # raises KeyboardInterrupt
And here is the decorator itself:
def exit_after(s):
'''
use as decorator to exit process if
function takes longer than s seconds
'''
def outer(fn):
def inner(*args, **kwargs):
timer = threading.Timer(s, quit_function, args=[fn.__name__])
timer.start()
try:
result = fn(*args, **kwargs)
finally:
timer.cancel()
return result
return inner
return outer
And here's the usage that directly answers your question about exiting after 5 seconds!:
@exit_after(5)
def countdown(n):
print('countdown started', flush=True)
for i in range(n, -1, -1):
print(i, end=', ', flush=True)
sleep(1)
print('countdown finished')
Demo:
>>> countdown(3)
countdown started
3, 2, 1, 0, countdown finished
>>> countdown(10)
countdown started
10, 9, 8, 7, 6, countdown took too long
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 11, in inner
File "<stdin>", line 6, in countdown
KeyboardInterrupt
The second function call will not finish, instead the process should exit with a traceback!
KeyboardInterrupt
does not always stop a sleeping threadNote that sleep will not always be interrupted by a keyboard interrupt, on Python 2 on Windows, e.g.:
@exit_after(1)
def sleep10():
sleep(10)
print('slept 10 seconds')
>>> sleep10()
sleep10 took too long # Note that it hangs here about 9 more seconds
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 11, in inner
File "<stdin>", line 3, in sleep10
KeyboardInterrupt
nor is it likely to interrupt code running in extensions unless it explicitly checks for PyErr_CheckSignals()
, see Cython, Python and KeyboardInterrupt ignored
I would avoid sleeping a thread more than a second, in any case - that's an eon in processor time.
How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it and does something else?
To catch it and do something else, you can catch the KeyboardInterrupt.
>>> try:
... countdown(10)
... except KeyboardInterrupt:
... print('do something else')
...
countdown started
10, 9, 8, 7, 6, countdown took too long
do something else
Did you try format?
@font-face {
font-family: 'The name of the Font Family Here';
src: URL('font.ttf') format('truetype');
}
Read this article: http://css-tricks.com/snippets/css/using-font-face/
Also, might depend on browser as well.
The recommended way is to use a Mutex. You can check out a sample here : http://www.codeproject.com/KB/cs/singleinstance.aspx
In specific the code:
///
/// check if given exe alread running or not
///
/// returns true if already running
private static bool IsAlreadyRunning()
{
string strLoc = Assembly.GetExecutingAssembly().Location;
FileSystemInfo fileInfo = new FileInfo(strLoc);
string sExeName = fileInfo.Name;
bool bCreatedNew;
Mutex mutex = new Mutex(true, "Global\\"+sExeName, out bCreatedNew);
if (bCreatedNew)
mutex.ReleaseMutex();
return !bCreatedNew;
}
StringBuilder s = new StringBuilder(token.length());
CharacterIterator it = new StringCharacterIterator(token);
for (char ch = it.first(); ch != CharacterIterator.DONE; ch = it.next()) {
switch (ch) {
case '&':
s.append("&");
break;
case '<':
s.append("<");
break;
case '>':
s.append(">");
break;
default:
s.append(ch);
break;
}
}
token = s.toString();
The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to enable a layer to show yourself, there is a simple call to the GoogleMaps instance you created with your map.
The actual documentation that Google provides gives you your answer. You just need to
// map is a GoogleMap object
map.isMyLocationEnabled = true
// map is a GoogleMap object
map.setMyLocationEnabled(true);
and watch the magic happen.
Just make sure that you have location permission and requested it at runtime on API Level 23 (M) or above
A recent project has a similar requirement. I wrote this decimal extension method, which uses the currency ("C") Format Specifier. In addition to removing zeros, it also has options for decimal digits precision, currency symbol, separator and culture.
public static DecimalExtension{
public static string ToCurrency(this decimal val,
int precision = 2,
bool currencySymbol = false,
bool separator = false,
CultureInfo culture = null)
{
if(culture == null) culture = new CultureInfo("en-US");
NumberFormatInfo nfi = culture.NumberFormat;
nfi.CurrencyDecimalDigits = precision;
string zeros = new String('0', precision);
//Remove zeros
var result = val.ToString("C",fi).Replace(nfi.CurrencyDecimalSeparator + zeros,"");
if(!separator) result = result.Replace(nfi.CurrencyGroupSeparator,"");
return currencySymbol? result: result.Replace(nfi.CurrencySymbol,"");
}
}
Examples:
decimal Total = 123.00M;
Console.WriteLine(Total.ToCurrency());
//output: 123
decimal Total = 1123.12M;
Console.WriteLine(Total.ToCurrency());
//Output: 1123.12
Console.WriteLine(Total.ToCurrency(4));
//Output: 1123.1200
Console.WriteLine(Total.ToCurrency(2,true,true));
//output: $1,123.12
CultureInfo culture = new CultureInfo("pt-BR") //Brazil
Console.WriteLine(Total.ToCurrency(2,true,true, culture));
//output: R$ 1.123,12
I just figured out that for a case where the path involves the use of white space characters, for example, when I need to access the app xyz
which location is :
C:\Program Files\ab cd\xyz.exe
To run this from windows cmd prompt, you need to use
C:\"Program Files"\"ab cd"\xyz.exe
or
"C:\Program Files\ab cd\xyz.exe"
It seems like what you want is http://msdn.microsoft.com/en-us/library/ms186323.aspx.
In your example it would be (starts with):
set @isExpress = (CharIndex('Express Edition', @edition) = 1)
Or contains
set @isExpress = (CharIndex('Express Edition', @edition) >= 1)
I use Inconsolata with UltraEdit on Windows. With TextMate (on the Mac) I prefer Monaco (it's the default font).
You can get the actual height of called layout with this code:
public int getLayoutSize() {
// Get the layout id
final LinearLayout root = (LinearLayout) findViewById(R.id.mainroot);
final AtomicInteger layoutHeight = new AtomicInteger();
root.post(new Runnable() {
public void run() {
Rect rect = new Rect();
Window win = getWindow(); // Get the Window
win.getDecorView().getWindowVisibleDisplayFrame(rect);
// Get the height of Status Bar
int statusBarHeight = rect.top;
// Get the height occupied by the decoration contents
int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
// Calculate titleBarHeight by deducting statusBarHeight from contentViewTop
int titleBarHeight = contentViewTop - statusBarHeight;
Log.i("MY", "titleHeight = " + titleBarHeight + " statusHeight = " + statusBarHeight + " contentViewTop = " + contentViewTop);
// By now we got the height of titleBar & statusBar
// Now lets get the screen size
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenHeight = metrics.heightPixels;
int screenWidth = metrics.widthPixels;
Log.i("MY", "Actual Screen Height = " + screenHeight + " Width = " + screenWidth);
// Now calculate the height that our layout can be set
// If you know that your application doesn't have statusBar added, then don't add here also. Same applies to application bar also
layoutHeight.set(screenHeight - (titleBarHeight + statusBarHeight));
Log.i("MY", "Layout Height = " + layoutHeight);
// Lastly, set the height of the layout
FrameLayout.LayoutParams rootParams = (FrameLayout.LayoutParams)root.getLayoutParams();
rootParams.height = layoutHeight.get();
root.setLayoutParams(rootParams);
}
});
return layoutHeight.get();
}
You can also reference a local gem with git if you happen to be working on it.
gem 'foo',
:git => '/Path/to/local/git/repo',
:branch => 'my-feature-branch'
Then, if it changes I run
bundle exec gem uninstall foo
bundle update foo
But I am not sure everyone needs to run these two steps.
I found the approach given by cimmanon and Kurt Mueller almost worked, but that I needed a parent reference (i.e., I need to add the '&' prefix to each vendor prefix); like this:
@mixin placeholder {
&::-webkit-input-placeholder {@content}
&:-moz-placeholder {@content}
&::-moz-placeholder {@content}
&:-ms-input-placeholder {@content}
}
I use the mixin like this:
input {
@include placeholder {
font-family: $base-font-family;
color: red;
}
}
With the parent reference in place, then correct css gets generated, e.g.:
input::-webkit-input-placeholder {
font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Liberation Serif", Georgia, serif;
color: red;
}
Without the parent reference (&), then a space is inserted before the vendor prefix and the CSS processor ignores the declaration; that looks like this:
input::-webkit-input-placeholder {
font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Liberation Serif", Georgia, serif;
color: red;
}
The fastest...
var removeChilds = function (node) {
var last;
while (last = node.lastChild) node.removeChild(last);
};
Thanks to Andrey Lushnikov for his link to jsperf.com (cool site!).
EDIT: to be clear, there is no performance difference in Chrome between firstChild and lastChild. The top answer shows a good solution for performance.
It means you haven't assigned a provisioning profile to the configuration.
Usually it's because "Any iOS SDK" must have a profile and cannot be set to "Don't sign".
All this and more is answered in the TN2250 Tech Note about Code Signing and Troubleshooting.
a bit more smart (python 3) way:
def printvars():
tmp = globals().copy()
[print(k,' : ',v,' type:' , type(v)) for k,v in tmp.items() if not k.startswith('_') and k!='tmp' and k!='In' and k!='Out' and not hasattr(v, '__call__')]
dictionary's setdefault is a good way to update an existing dict entry if it's there, or create a new one if it's not all in one go:
Looping style:
# This is our sample data
data = [("Milter", "Miller", 4), ("Milter", "Miler", 4), ("Milter", "Malter", 2)]
# dictionary we want for the result
dictionary = {}
# loop that makes it work
for realName, falseName, position in data:
dictionary.setdefault(realName, {})[falseName] = position
dictionary now equals:
{'Milter': {'Malter': 2, 'Miler': 4, 'Miller': 4}}
Server configuration is not a solution for an SPA is what even I think. You dont want to reload an angular SPA again if a wrong route comes in, do you? So I will not depend on a server route and redirect to other route but yes I will let index.html handle all the requests for angular routes of the angular app path.
Try this instead of otherwise or wrong routes. It works for me, not sure but seems like work in progress. Stumbled this myself when facing an issue.
@RouteConfig([
{ path: '/**', redirectTo: ['MycmpnameCmp'] },
...
}
])
https://github.com/angular/angular/issues/4055
However remember to configure your server folders and access right in case you have HTML or web scripts which are not SPA. Else you will face issues. For me when facing issue like you it was a mix of server configuration and above.
In order to find chart data using the financial data API of Google, one must simply go to Google as if looking for a search term, type finance into the search engine, and a link to Google finance will appear. Once at the Google finance search engine, type the ticker name into the financial data API engine and the result will be displayed. However, it should be noted that all Google finance charts are delayed by 15 minutes, and at most can be used for a better understanding of the ticker's past history, rather than current price.
A solution to the delayed chart information is to obtain a real-time financial data API. An example of one would be the barchartondemand interface that has real-time quote information, along with other detailed features that make it simpler to find the exact chart you're looking for. With fully customizable features, and specific programming tools for the precise trading information you need, barchartondemand's tools outdo Google finance by a wide margin.
In addition to being able to add a number of days to a date, you can use interval data types assuming you are on Oracle 9i

You can specify git log
options to show only the last commit, -1
, and a format that includes only the commit ID, like this:
git log -1 --format=%H
If you prefer the shortened commit ID:
git log -1 --format=%h
I use msysgit to install gcc on Windows, it has a nice installer which installs most everything that you might need. Most devs will need more than just the compiler, e.g. the shell, shell tools, make, git, svn, etc. msysgit comes with all of that. https://msysgit.github.io/
edit: I am now using msys2. Msys2 uses pacman
from Arch Linux to install packages, and includes three environments, for building msys2 apps, 32-bit native apps, and 64-bit native apps. (You probably want to build 32-bit native apps.)
You could also go full-monty and install code::blocks or some other gui editor that comes with a compiler. I prefer to use vim and make.
My favourite has always been gnuplot. It's very extensive, so it might be a bit too complex for your needs though. It is cross-platform and there is a C++ API.
The problem is actually that you need to double-escape backslashes in the replacement string. You see, "\\/"
(as I'm sure you know) means the replacement string is \/
, and (as you probably don't know) the replacement string \/
actually just inserts /
, because Java is weird, and gives \
a special meaning in the replacement string. (It's supposedly so that \$
will be a literal dollar sign, but I think the real reason is that they wanted to mess with people. Other languages don't do it this way.) So you have to write either:
"Hello/You/There".replaceAll("/", "\\\\/");
or:
"Hello/You/There".replaceAll("/", Matcher.quoteReplacement("\\/"));
def func(a, b, c, d):
return a + b * c % d
map(lambda x: func(*x), [[1,2,3,4], [5,6,7,8]])
By wrapping the function call with a lambda and using the star unpack, you can do map with arbitrary number of arguments.
Create your repository in git hub
Allow to track your project by GIT
If you get another error message, read carefully what it says. Is it saying git isn't installed on your computer by saying that the word 'git' is not recognized? Is it saying that you're already in a folder or sub-folder where git is initialized? Google your error and/or output to understand it, and to figure out how to fix it.
now run following command
#echo "your git hub repository name" >> README.md git init git add README.md git commit -m "first commit" git remote add origin https:// #
above block you will get when first time you are opening your repository
If error occurs or nothing happens after last command run"git push -u origin master" dont worry
go to folder where code is available and through git extention push it to git [URL], branch
Option 1 is the only good solution.
Option 2 does the same but you repeat the column name lots of times; additionally the SQL engine doesn't immediately know that you want to check if the value is one of the values in a fixed list. However, a good SQL engine could optimize it to have equal performance like with IN
. There's still the readability issue though...
Option 3 is simply horrible performance-wise. It sends a query every loop and hammers the database with small queries. It also prevents it from using any optimizations for "value is one of those in a given list"
You have to read
database column
here. You could have a look on following code snippet
string connectionString = ConfigurationManager.ConnectionStrings["NameOfYourSqlConnectionString"].ConnectionString;
using (var _connection = new SqlConnection(connectionString))
{
_connection.Open();
using (SqlCommand command = new SqlCommand("SELECT SomeColumnName FROM TableName", _connection))
{
SqlDataReader sqlDataReader = command.ExecuteReader();
if (sqlDataReader.HasRows)
{
while (sqlDataReader.Read())
{
string YourFirstDataBaseTableColumn = sqlDataReader["SomeColumn"].ToString(); // Remember Type Casting is required here it has to be according to database column data type
string YourSecondDataBaseTableColumn = sqlDataReader["SomeColumn"].ToString();
string YourThridDataBaseTableColumn = sqlDataReader["SomeColumn"].ToString();
}
}
sqlDataReader.Close();
}
_connection.Close();
If Perl is an option, you can try this:
perl -ne 'printf "%s,$_" , $.-1' file
$_
is the line
$.
is the line number
Here's a simple example of how to load JSON data into an Angular model.
I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.
http://www.iNorthwind.com/Service1.svc/getAllCustomers
It returns some JSON data which looks like this:
{
"GetAllCustomersResult" :
[
{
"CompanyName": "Alfreds Futterkiste",
"CustomerID": "ALFKI"
},
{
"CompanyName": "Ana Trujillo Emparedados y helados",
"CustomerID": "ANATR"
},
{
"CompanyName": "Antonio Moreno Taquería",
"CustomerID": "ANTON"
}
]
}
..and I want to populate a drop down list with this data, to look like this...
I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.
How would I do it ?
My Angular controller would look like this:
function MikesAngularController($scope, $http) {
$scope.listOfCustomers = null;
$http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
.success(function (data) {
$scope.listOfCustomers = data.GetAllCustomersResult;
})
.error(function (data, status, headers, config) {
// Do some error handling here
});
}
... which fills a "listOfCustomers" variable with this set of JSON data.
Then, in my HTML page, I'd use this:
<div ng-controller='MikesAngularController'>
<span>Please select a customer:</span>
<select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>
And that's it. We can now see a list of our JSON data on a web page, ready to be used.
The key to this is in the "ng-options" tag:
customer.CustomerID as customer.CompanyName for customer in listOfCustomers
It's a strange syntax to get your head around !
When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.
The full script for this example can be found here:

I use SourceTree git client, and I see that their initial commit/push command is:
git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags --set-upstream origin master:master
Or you can just use this library to get all errors, even from deep and dynamic forms.
npm i @naologic/forms
If you want to use the static function on your own forms
import {NaoFormStatic} from '@naologic/forms';
...
const errorsFlat = NaoFormStatic.getAllErrorsFlat(fg);
console.log(errorsFlat);
If you want to use NaoFromGroup
you can import and use it
import {NaoFormGroup, NaoFormControl, NaoValidators} from '@naologic/forms';
...
this.naoFormGroup = new NaoFormGroup({
firstName: new NaoFormControl('John'),
lastName: new NaoFormControl('Doe'),
ssn: new NaoFormControl('000 00 0000', NaoValidators.isSSN()),
});
const getFormErrors = this.naoFormGroup.getAllErrors();
console.log(getFormErrors);
// --> {first: {ok: false, isSSN: false, actualValue: "000 00 0000"}}
