A useful 2D vector operation is a cross product that returns a scalar. I use it to see if two successive edges in a polygon bend left or right.
From the Chipmunk2D source:
/// 2D vector cross product analog.
/// The cross product of 2D vectors results in a 3D vector with only a z component.
/// This function returns the magnitude of the z value.
static inline cpFloat cpvcross(const cpVect v1, const cpVect v2)
{
return v1.x*v2.y - v1.y*v2.x;
}

The scipy.stats.mode
function has been significantly optimized since this post, and would be the recommended method
Old answer
This is a tricky problem, since there is not much out there to calculate mode along an axis. The solution is straight forward for 1-D arrays, where numpy.bincount
is handy, along with numpy.unique
with the return_counts
arg as True
. The most common n-dimensional function I see is scipy.stats.mode, although it is prohibitively slow- especially for large arrays with many unique values. As a solution, I've developed this function, and use it heavily:
import numpy
def mode(ndarray, axis=0):
# Check inputs
ndarray = numpy.asarray(ndarray)
ndim = ndarray.ndim
if ndarray.size == 1:
return (ndarray[0], 1)
elif ndarray.size == 0:
raise Exception('Cannot compute mode on empty array')
try:
axis = range(ndarray.ndim)[axis]
except:
raise Exception('Axis "{}" incompatible with the {}-dimension array'.format(axis, ndim))
# If array is 1-D and numpy version is > 1.9 numpy.unique will suffice
if all([ndim == 1,
int(numpy.__version__.split('.')[0]) >= 1,
int(numpy.__version__.split('.')[1]) >= 9]):
modals, counts = numpy.unique(ndarray, return_counts=True)
index = numpy.argmax(counts)
return modals[index], counts[index]
# Sort array
sort = numpy.sort(ndarray, axis=axis)
# Create array to transpose along the axis and get padding shape
transpose = numpy.roll(numpy.arange(ndim)[::-1], axis)
shape = list(sort.shape)
shape[axis] = 1
# Create a boolean array along strides of unique values
strides = numpy.concatenate([numpy.zeros(shape=shape, dtype='bool'),
numpy.diff(sort, axis=axis) == 0,
numpy.zeros(shape=shape, dtype='bool')],
axis=axis).transpose(transpose).ravel()
# Count the stride lengths
counts = numpy.cumsum(strides)
counts[~strides] = numpy.concatenate([[0], numpy.diff(counts[~strides])])
counts[strides] = 0
# Get shape of padded counts and slice to return to the original shape
shape = numpy.array(sort.shape)
shape[axis] += 1
shape = shape[transpose]
slices = [slice(None)] * ndim
slices[axis] = slice(1, None)
# Reshape and compute final counts
counts = counts.reshape(shape).transpose(transpose)[slices] + 1
# Find maximum counts and return modals/counts
slices = [slice(None, i) for i in sort.shape]
del slices[axis]
index = numpy.ogrid[slices]
index.insert(axis, numpy.argmax(counts, axis=axis))
return sort[index], counts[index]

A SurfaceView
is a custom view in Android that can be used to drawn inside it.
The main difference between a View
and a SurfaceView
is that a View is drawn in the
UI Thread
, which is used for all the user interaction.
If you want to update the UI rapidly enough and render a good amount of information in
it, a SurfaceView is a better choice.
But there are a few technical insides to the SurfaceView
:
1. They are not hardware accelerated.
2. Normal views are rendered when you call the methods invalidate
or postInvalidate()
, but this does not mean the view will be
immediately updated (A VSYNC
will be sent, and the OS decides when
it gets updated. The SurfaceView
can be immediately updated.
3. A SurfaceView has an allocated surface buffer
, so it is more costly
No need to do so much of trouble! Its simple
This will create 2 * 3 matrix of string.
var array=[];
var x = 2, y = 3;
var s = 'abcdefg';
for(var i = 0; i<x; i++){
array[i]=new Array();
for(var j = 0; j<y; j++){
array[i].push(s.charAt(counter++));
}
}
If you do not care about predictable run time you could try by first splitting your polygons into unions of convex polygons and then pairwise computing the intersection between the sub-polygons.
This would give you a collection of convex polygons such that their union is exactly the intersection of your starting polygons.
I find a nice and tidy Wave game engine few days ago. It uses C# and have Windows Phone and Windows Store converters as well which makes it a great replacement of XNA for me
Real problem is when you need draw some tile/sprites intersecting/spanning two or more other tiles.
After 2 (hard) months of personal analisys of problem I finally found and implemented a "correct render drawing" for my new cocos2d-js game. Solution consists in mapping, for each tile (susceptible), which sprites are "front, back, top and behind". Once doing that you can draw them following a "recursive logic".
I was getting a very similar situation where the HttpWebRequest wasn't picking up the correct proxy details by default and setting the UseDefaultCredentials didn't work either. Forcing the settings in code however worked a treat:
IWebProxy proxy = myWebRequest.Proxy;
if (proxy != null) {
string proxyuri = proxy.GetProxy(myWebRequest.RequestUri).ToString();
myWebRequest.UseDefaultCredentials = true;
myWebRequest.Proxy = new WebProxy(proxyuri, false);
myWebRequest.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
}
and because this uses the default credentials it should not ask the user for their details.
Responsive Web design (RWD) is a Web design approach aimed at crafting sites to provide an optimal viewing experience
When you design your responsive website you should consider the size of the screen and not the device type. The media queries helps you do that.
If you want to style your site per device, you can use the user agent
value, but this is not recommended since you'll have to work hard to maintain your code for new devices, new browsers, browsers versions etc while when using the screen size, all of this does not matter.
You can see some standard resolutions in this link.
BUT, in my opinion, you should first design your website layout, and only then adjust it with media queries to fit possible screen sizes.
Why? As I said before, the screen resolutions variety is big and if you'll design a mobile version that is targeted to 320px your site won't be optimized to 350px screens or 400px screens.
TIPS
Example
I have a table with 5 columns. The data looks good when the screen size is bigger than 600px so I add a breakpoint at 600px and hides 1 less important column when the screen size is smaller. Devices with big screens such as desktops and tablets will display all the data, while mobile phones with small screens will display part of the data.
State of mind
Not directly related to the question but important aspect in responsive design. Responsive design also relate to the fact that the user have a different state of mind when using a mobile phone or a desktop. For example, when you open your bank's site in the evening and check your stocks you want as much data on the screen. When you open the same page in the your lunch break your probably want to see few important details and not all the graphs of last year.
I recommend always using a named range (as you have suggested you are doing) because if any columns or rows are added or deleted, the name reference will update, whereas if you hard code the cell reference (eg "H1" as suggested in one of the responses) in VBA, then it will not update and will point to the wrong cell.
So
Range("RefNo") = InputBox("....")
is safer than
Range("H1") = InputBox("....")
You can set the value of several cells, too.
Range("Results").Resize(10,3) = arrResults()
where arrResults is an array of at least 10 rows & 3 columns (and can be any type). If you use this, put this
Option Base 1
at the top of the VBA module, otherwise VBA will assume the array starts at 0 and put a blank first row and column in the sheet. This line makes all arrays start at 1 as a default (which may be abnormal in most languages but works well with spreadsheets).
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()

Prior to C++11, you cannot initialise an array using type[]. However the latest c++11 provides(unifies) the initialisation, so you can do it in this way:
string* pStr = new string[3] { "hi", "there"};

Actually the Read

In terms of bytecode, in
saves a LOAD_ATTR
and replaces a CALL_FUNCTION
with a COMPARE_OP
.

2 0 LOAD_GLOBAL 0 (name)
3 LOAD_GLOBAL 1 (d)
6 COMPARE_OP 6 (in)
9 POP_TOP
>>> dis.dis(haskey)
2 0 LOAD_GLOBAL 0 (d)
3 LOAD_ATTR 1 (haskey)
6 LOAD_GLOBAL 2 (name)
9 CALL_FUNCTION 1
12 POP_TOP
My feelings are that in
is much more readable and is to be preferred in every case that I can think of.
In terms of performance, the timing reflects the opcode
$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "'foo' in d"
10000000 loops, best of 3: 0.11 usec per loop
$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "d.has_key('foo')"
1000000 loops, best of 3: 0.205 usec per loop
in
is almost twice as fast.
Or you can use relative units, e.g.

According to this documentation, the find method will search down through the tree of elements until it finds the element in the selector parameters. So $(parentSelector).find(childSelector)
is the fastest and most efficient way to do this.

@Ryan Cavanaugh's answer is totally ok and still valid. Still it worth to add that as of Fall'16 when we can claim that ES6 is supported by the majority of platforms it almost always better to stick to Map whenever you need associate some data with some key.
When we write let a: { [s: string]: string; }
we need to remember that after typescript compiled there's not such thing like type data, it's only used for compiling. And { [s: string]: string; } will compile to just {}.
That said, even if you'll write something like:
class TrickyKey {}
let dict: {[key:TrickyKey]: string} = {}
This just won't compile (even for target es6
, you'll get error TS1023: An index signature parameter type must be 'string' or 'number'.
So practically you are limited with string or number as potential key so there's not that much of a sense of enforcing type check here, especially keeping in mind that when js tries to access key by number it converts it to string.
So it is quite safe to assume that best practice is to use Map even if keys are string, so I'd stick with:
let staff: Map<string, string> = new Map();
How to import images into the gallery of an Android Virtual Device using Android Studio: I'm using Android Studio 1.4.1 and a API 15 virtual device.
Warning: This is manual intensive so it is not a good solution for a large number of images.
Putting the model dot property in strings worked for me: ModelState.AddModelError("Item1.Month", "This is not a valid date");
Using only base, I wrote the following function.
Note:
Fine-tune to suit your needs.
findWeekNo <- function(myDate){
# Find out the start day of week 1; that is the date of first Mon in the year
weekday <- switch(weekdays(as.Date(paste(format(as.Date(myDate),"%Y"),"01-01", sep = "-"))),
"Monday"={1},
"Tuesday"={2},
"Wednesday"={3},
"Thursday"={4},
"Friday"={5},
"Saturday"={6},
"Sunday"={7}
)
firstMon <- ifelse(weekday==1,1, 9 - weekday )
weekNo <- floor((as.POSIXlt(myDate)$yday - (firstMon-1))/7)+1
return(weekNo)
}
findWeekNo("2017-01-15") # 2
Empty
refers to a variable being at its default value. So if you check if a cell with a value of 0 = Empty
then it would return true.
IsEmpty
refers to no value being initialized.
In a nutshell, if you want to see if a cell is empty (as in nothing exists in its value) then use IsEmpty
. If you want to see if something is currently in its default value then use Empty
.

you need to do:
let fileUrl = URL(string: filePath)
or
let fileUrl = URL(fileURLWithPath: filePath)
depending on your needs. See URL docs
Before Swift 3, URL was called NSURL.
This isn't a direct answer, but rather a slightly different design direction:
Do not post the data as a form, but as a JSON object to be directly mapped to server-side object, or use REST style path variable
Now I know neither option might be suitable in your case since you're trying to pass a XSRF key. Mapping it into a path variable like this is a terrible design:
http://www.someexample.com/xsrf/{xsrfKey}
Because by nature you would want to pass xsrf key to other path too, /login
, /book-appointment
etc. and you don't want to mess your pretty URL
Interestingly adding it as an object field isn't appropriate either, because now on each of json object you pass to server you have to add the field
{
appointmentId : 23,
name : 'Joe Citizen',
xsrf : '...'
}
You certainly don't want to add another field on your server-side class which does not have a direct semantic association with the domain object.
In my opinion the best way to pass your xsrf key is via a HTTP header. Many xsrf protection server-side web framework library support this. For example in Java Spring, you can pass it using X-CSRF-TOKEN
header.
Angular's excellent capability of binding JS object to UI object means we can get rid of the practice of posting form all together, and post JSON instead. JSON can be easily de-serialized into server-side object and support complex data structures such as map, arrays, nested objects, etc.
How do you post array in a form payload? Maybe like this:
shopLocation=downtown&daysOpen=Monday&daysOpen=Tuesday&daysOpen=Wednesday
or this:
shopLocation=downtwon&daysOpen=Monday,Tuesday,Wednesday
Both are poor design..
>>> import subprocess
>>> subprocess.call('echo $HOME')
Traceback (most recent call last):
...
OSError: [Errno 2] No such file or directory
>>>
>>> subprocess.call('echo $HOME', shell=True)
/user/khong
0
Setting the shell argument to a true value causes subprocess to spawn an intermediate shell process, and tell it to run the command. In other words, using an intermediate shell means that variables, glob patterns, and other special shell features in the command string are processed before the command is run. Here, in the example, $HOME was processed before the echo command. Actually, this is the case of command with shell expansion while the command ls -l considered as a simple command.

cmdlet
Invoke-Sqlcmd -Query "SELECT GETDATE() AS TimeOfQuery;" -ServerInstance "MyComputer\MyInstance"
If you're looking for something more straight forward to implement (and it doesn't include pie/donut charts) then I recommend WilliamChart. Specially if motion takes an important role in your app design. In other hand if you want featured charts, then go for MPAndroidChart.
To create a "drop down menu" you can use OptionMenu
in tkinter
Example of a basic OptionMenu
:
from Tkinter import *
master = Tk()
variable = StringVar(master)
variable.set("one") # default value
w = OptionMenu(master, variable, "one", "two", "three")
w.pack()
mainloop()
More information (including the script above) can be found here.
Creating an OptionMenu
of the months from a list would be as simple as:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
mainloop()
In order to retrieve the value the user has selected you can simply use a .get()
on the variable that we assigned to the widget, in the below case this is variable
:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
def ok():
print ("value is:" + variable.get())
button = Button(master, text="OK", command=ok)
button.pack()
mainloop()
I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

While LIKE
is suitable for this case, a more general purpose solution is to use instr
, which doesn't require characters in the search string to be escaped. Note: instr
is available starting from Sqlite 3.7.15.
SELECT *
FROM TABLE
WHERE instr(column, 'cats') > 0;
Also, keep in mind that LIKE
is case-insensitive, whereas instr
is case-sensitive.
$_SERVER["PHP_SELF"];
will give you the current filename and its path, but basename(__FILE__)
should give you the filename that it is called from.
So
if(basename(__FILE__) == 'file_name.php') {
//Hide
} else {
//show
}
should do it.
It’s just HTML with Server Side Includes.
What about in one single line...
$('#txtSample').focus().val($('#txtSample').val());
This line works for me.
You could also use the extension model:
public enum MyEnum
{
[Description("String 1")]
V1= 1,
[Description("String 2")]
V2= 2
}
Your Extension Class
public static class MyEnumExtensions
{
public static string ToDescriptionString(this MyEnum val)
{
DescriptionAttribute[] attributes = (DescriptionAttribute[])val
.GetType()
.GetField(val.ToString())
.GetCustomAttributes(typeof(DescriptionAttribute), false);
return attributes.Length > 0 ? attributes[0].Description : string.Empty;
}
}
usage:
MyEnum myLocal = MyEnum.V1;
print(myLocal.ToDescriptionString());
This is an exact fix to your problem, but I would advise against initializing the matrix with a default value that represents '0' or 'undefined', as Arrays in javascript are just regular objects, so you wind up wasting effort. If you want to default the cells to some meaningful value, then this snippet will work well, but if you want an uninitialized matrix, don't use this version:
/**
* Generates a matrix (ie: 2-D Array) with:
* 'm' columns,
* 'n' rows,
* every cell defaulting to 'd';

If you would rather just create an uninitialized 2-D Array, then this will be more efficient than unnecessarily initializing every entry:
/**
* Generates a matrix (ie: 2-D Array) with:
* 'm' columns,
* 'n' rows,
* every cell remains 'undefined';
*/
function Matrix(m, n){
var mat = Array.apply(null, new Array(m)).map(
Array.prototype.valueOf,
new Array(n)

return mat;
}
Usage:
< Matrix(3,2);
> Array [ Array[2], Array[2], Array[2] ]
Use COALESCE()
instead:
SELECT COALESCE(Field,'Empty') from Table;
It functions much like ISNULL
, although provides more functionality. Coalesce will return the first non null value in the list. Thus:
SELECT COALESCE(null, null, 5);
returns 5, while
SELECT COALESCE(null, 2, 5);
returns 2
Coalesce will take a large number of arguments. There is no documented maximum. I tested it will 100 arguments and it succeeded. This should be plenty for the vast majority of situations.
Update Bootstrap 4
Bootstrap 4 has utility classes that make it easier to create a full screen carousel. For example, use the min-vh-100
class on the carousel-item
content...
<div class="carousel slide" data-ride="carousel">
<div class="carousel-inner bg-info" role="listbox">
<div class="carousel-item active">
<div class="d-flex align-items-center justify-content-center min-vh-100">
<h1 class="display-1">ONE</h1>
</div>
</div>
</div>
</div>
This works to make the carousel items full screen, but carousel items that contain images or videos that have a specific size & aspect ratio require further consideration.
Since the viewport h/w ratio is likely to be different than the image or video h/w ratio, usually background images or object-fit
are commonly used to size images and videos to "full screen". For videos, use the Bootstrap responsive embed classes as needed for the video ratio (21:9, 19:9, etc...).
Also see: https://stackoverflow.com/a/58765043/171456
Original answer (Bootstrap 3)
Make sure the img inside the carousel item is set to height and width 100%. You also have to make sure the carousel and any of the .item containers (html,body) are 100%...
html,body{height:100%;}
.carousel,.item,.active{height:100%;}
.carousel-inner{height:100%;}

It tells you what are the shortcuts you use/don't use and displays usage statistics. It will guide you to the unknown features.
If the scripts are loaded within the <head>
of the document, then it's possible use the defer
attribute in script tag.
Example:
<script src="demo_defer.js" defer></script>
From https://developer.mozilla.org:
defer
This Boolean attribute is set to indicate to a browser that the script is meant to be executed after the document has been parsed, but before firing DOMContentLoaded.
This attribute must not be used if the src attribute is absent (i.e. for inline scripts), in this case it would have no effect.
To achieve a similar effect for dynamically inserted scripts use async=false instead. Scripts with the defer attribute will execute in the order in which they appear in the document.
In my case I deployed via a YAML file like kubectl apply -f deployment.yaml
and the solution appears to be to delete via kubectl delete -f deployment.yaml
It seems all the answers assume high level languages and mainly C/C++.
But the question is tagged "assembly" and in all assemblers I know (for 8bit, 16bit, 32bit and 64bit CPUs), the definitions are much more clear:
byte = 8 bits
word = 2 bytes
dword = 4 bytes = 2Words (dword means "double word")
qword = 8 bytes = 2Dwords = 4Words ("quadruple word")
You are lucky that you didn't complete the rebase, so you can still do git rebase --abort
. If you had completed the rebase (it rewrites history), things would have been much more complex. Consider tagging the tips of branches before doing potentially damaging operations (particularly history rewriting), that way you can rewind if something blows up.
I had the same issue, and found a solution. Try this: %0D%0A
to add a line break.
If you want many inserts
from rope.base.codeanalyze import ChangeCollector
c = ChangeCollector(code)
c.add_change(5, 5, '<span style="background-color:#339999;">')
c.add_change(10, 10, '</span>')
rend_code = c.get_changed()
Just finish it up.

Static method is inherited in subclass but it is not polymorphism. When you writing the implementation of static method, the parent's class method is over hidden, not overridden. Think, if it is not inherited then how you can be able to access without classname.staticMethodname();
?
Suppose a 9800GT GPU:

A block cannot have more active threads than 512 therefore __syncthreads
can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:
func1();
__syncthreads();
func2();
__syncthreads();
then the kernel must run twice and the order of execution will be:
Note:
The main point is __syncthreads
is a block-wide operation and it does not synchronize all threads.
I'm not sure about the exact number of threads that __syncthreads
can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.
Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads
.
I would greatly appreciate if someone test this again for a more accurate piece of information.
If anyone like me likes chainable data manipulation using the pandas dot notation (like piping), then the following may be useful:
df3 = df3.query('~index.duplicated()')
This enables chaining statements like this:
df3.assign(C=2).query('~index.duplicated()').mean()

You shouldn't use CascadeType.ALL
on @ManyToOne
since entity state transitions should propagate from parent entities to child ones, not the other way around.
The @ManyToOne
side is always the Child association since it maps the underlying Foreign Key column.
Therefore, you should move the CascadeType.ALL
from the @ManyToOne
association to the @OneToMany
side, which should also use the mappedBy
attribute since it's the most efficient one-to-many table relationship mapping.
Try this:
CREATE TABLE IF NOT EXISTS app_user (
username varchar(45) NOT NULL,
password varchar(450) NOT NULL,
enabled integer NOT NULL DEFAULT '1',
PRIMARY KEY (username)
)
legacy system support. If you have a system that is using the data and it is expected to be a certain length then the database is a good place to enforce the length. This is not ideal but legacy systems are sometime not ideal. =P
I'm new to both Python and PyQt5. I tried to use pip, but I was having problems with it using a Windows machine. If you have a version of Python 3.4 or above, pip is installed and ready to use like so:
python -m pip install pyqt5
That's of course assuming that the path for Python executable is in your PATH environment variable. Otherwise include the full path to Python executable (you can type where python
to the Command Window to find it) like:
C:\users\userName\AppData\Local\Programs\Python\Python34\python.exe -m pip install pyqt5

What you are trying to do is not possible. The reason for this is that in a POSIX system (Linux, OSX, etc), a child process cannot modify the environment of a parent process. This includes modifying the parent process's working directory and environment variables.
When you are on the commandline and you go to execute your Node script, your current process (bash
, zsh
, whatever) spawns a new process which has it's own environment, typically a copy of your current environment (it is possible to change this via system calls; but that's beyond the scope of this reply), allowing that process to do whatever it needs to do in complete isolation. When the subprocess exits, control is handed back to your shell's process, where the environment hasn't been affected.
There are a lot of reasons for this, but for one, imagine that you executed a script in the background (via ./foo.js &
) and as it ran, it started changing your working directory or overriding your PATH
. That would be a nightmare.
If you need to perform some actions that require changing your working directory of your shell, you'll need to write a function in your shell. For example, if you're running Bash, you could put this in your ~/.bash_profile
:
do_cool_thing() {
cd "/Users"
echo "Hey, I'm in $PWD"
}
and then this cool thing is doable:
$ pwd
/Users/spike
$ do_cool_thing
Hey, I'm in /Users
$ pwd
/Users
If you need to do more complex things in addition, you could always call out to your nodejs script from that function.
This is the only way you can accomplish what you're trying to do.
Check the location whether it's the right location of the git project.
There isn't currently a built-in PowerShell method for doing the SFTP part. You'll have to use something like psftp.exe or a PowerShell module like Posh-SSH.
Here is an example using Posh-SSH:
# Set the credentials
$Password = ConvertTo-SecureString 'Password1' -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ('root', $Password)
# Set local file path, SFTP path, and the backup location path which I assume is an SMB path
$FilePath = "C:\FileDump\test.txt"
$SftpPath = '/Outbox'
$SmbPath = '\\filer01\Backup'
# Set the IP of the SFTP server
$SftpIp = '10.209.26.105'
# Load the Posh-SSH module
Import-Module C:\Temp\Posh-SSH
# Establish the SFTP connection
$ThisSession = New-SFTPSession -ComputerName $SftpIp -Credential $Credential
# Upload the file to the SFTP path
Set-SFTPFile -SessionId ($ThisSession).SessionId -LocalFile $FilePath -RemotePath $SftpPath
#Disconnect all SFTP Sessions
Get-SFTPSession | % { Remove-SFTPSession -SessionId ($_.SessionId) }
# Copy the file to the SMB location
Copy-Item -Path $FilePath -Destination $SmbPath
Some additional notes:
That should give you a decent starting point.
I won't refer too your example as it is quite simple for a general answer (for example it doesn't contain templated functions ,which force you to implement them on the header) , what I follow as a rule of thumb is the pimpl idiom
It has quite some benefits as you get faster compilation times and the syntactic sugar :
class->member
instead of class.member
The only drawback is the extra pointer you pay.
My previous version of this answer had links, that kept becoming dead.

The easiest way to do that would be to use the Params plugin, introduced in beta5. It has utility methods to make it easy to access different types of parameters. As always, reading the tests can prove valuable to understand how something is supposed to be used.
To get the value of a named parameter in a controller, you will need to select the appropriate method for the type of parameter you are looking for and pass in the name.
$this->params()->fromPost('paramname'); // From POST
$this->params()->fromQuery('paramname'); // From GET
$this->params()->fromRoute('paramname'); // From RouteMatch
$this->params()->fromHeader('paramname'); // From header
$this->params()->fromFiles('paramname'); // From file being uploaded
All of these methods also support default values that will be returned if no parameter with the given name is found.
$orderBy = $this->params()->fromQuery('orderby', 'name');
When visiting http://example.com/?orderby=birthdate,
$orderBy will have the value birthdate.
When visiting http://example.com/,
$orderBy will have the default value name.
To get all parameters of one type, just don't pass in anything and the Params plugin will return an array of values with their names as keys.
$allGetValues = $this->params()->fromQuery(); // empty method call
When visiting http://example.com/?orderby=birthdate&filter=hasphone $allGetValues will be an array like
array(
'orderby' => 'birthdate',
'filter' => 'hasphone',
);
If you check the source code for the Params plugin, you will see that it's just a thin wrapper around other controllers to allow for more consistent parameter retrieval. If you for some reason want/need to access them directly, you can see in the source code how it's done.
$this->getRequest()->getRequest('name', 'default');
$this->getEvent()->getRouteMatch()->getParam('name', 'default');
NOTE: You could have used the superglobals $_GET, $_POST etc., but that is discouraged.

# open a public URL, in this case, the webbrowser docs

you can use any other browser by changing the parameter 'using' as given in a link
Whilst this an old question, I ran into this problem myself recently and some of the answers here are now deprecated (as the comments point out). So for the benefit of others who may have stumbled here:
A term
query can be used to find the exact term specified in the reverse index:
{
"query": {
"term" : { "tags" : "a" }
}
From the documenation https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html
Alternatively you can use a terms
query, which will match all documents with any of the items specified in the given array:
{
"query": {
"terms" : { "tags" : ["a", "c"]}
}
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html
One gotcha to be aware of (which caught me out) - how you define the document also makes a difference. If the field you're searching in has been indexed as a text
type then Elasticsearch will perform a full text search (i.e using an analyzed
string).
If you've indexed the field as a keyword
then a keyword search using a 'non-analyzed' string is performed. This can have a massive practical impact as Analyzed strings are pre-processed (lowercased, punctuation dropped etc.) See (https://www.elastic.co/guide/en/elasticsearch/guide/master/term-vs-full-text.html)
To avoid these issues, the string field has split into two new types: text, which should be used for full-text search, and keyword, which should be used for keyword search. (https://www.elastic.co/blog/strings-are-dead-long-live-strings)
>>> "+7".lstrip("-+").isdigit()
True
>>> "-7".lstrip("-+").isdigit()
True
>>> "7".lstrip("-+").isdigit()
True
>>> "13.4".lstrip("-+").isdigit()
False
So your function would be:
def is_int(val):
return val.lstrip("-+").isdigit()

You are not returning a response object from your view my_form_post
. The function ends with implicit return None
, which Flask does not like.
Make the function my_form_post
return an explicit response, for example
return 'OK'
at the end of the function.
I know it's an old question, but if someone is looking here again... see https://python-sounddevice.readthedocs.io/en/0.4.1/index.html .
It has a nice example "Input to Ouput Pass-Through" here https://python-sounddevice.readthedocs.io/en/0.4.1/examples.html#input-to-output-pass-through .
... and a lot of other examples as well ...
If you just want some values, you can just use the @ARGV array. But if you are looking for something more powerful in order to do some command line options processing, you should use Getopt::Long.
or even a very classic old fashion method
IEnumerable<string> collection = new List<string>() { "a", "b", "c" };
for(int i = 0; i < collection.Count(); i++)
{
string str1 = collection.ElementAt(i);
// do your stuff
}
maybe you would like this method also :-)
Add:
using System.Linq;
to the top of your file.
And then:
Car[] carList = ...
var carMake =
from item in carList
where item.Model == "bmw"
select item.Make;
or if you prefer the fluent syntax:
var carMake = carList
.Where(item => item.Model == "bmw")
.Select(item => item.Make);
Things to pay attention to:
item.Make
in the select
clause instead if s.Make
as in your code.item
and .Model
in your where
clauseTo be able to build with C# 6 syntax use this in path:
C:\Program Files (x86)\MSBuild\14.0\Bin
First install setuptools
sudo pip install setuptools
Then install mysql-connector
sudo pip install mysql-connector
If using Python3, then replace pip by pip3
I should add that the keeping your tests in the same package but in a parallel directory to the source being tested eliminates the bloat of the code once your ready to deploy it without having to do a bunch of exclude patterns.
I personally like the best practices described in "JUnit Pocket Guide" ... it's hard to beat a book written by the co-author of JUnit!
All the existing (working) answers have one of two problems:
1. Ignored Indices:
For the most part, when a column being searched has a function called on it (including implicitly, like for CAST
), the optimizer must ignore indices on the column and search through every record. Here's a quick example:
We're dealing with timestamps, and most RDBMSs tend to store this information as an increasing value of some sort, usually a long
or BIGINTEGER
count of milli-/nanoseconds. The current time thus looks/is stored like this:
1402401635000000 -- 2014-06-10 12:00:35.000000 GMT
You don't see the 'Year' value ('2014'
) in there, do you? In fact, there's a fair bit of complicated math to translate back and forth. So if you call any of the extraction/date part functions on the searched column, the server has to perform all that math just to figure out if you can include it in the results. On small tables this isn't an issue, but as the percentage of rows selected decreases this becomes a larger and larger drain. Then in this case, you're doing it a second time for asking about MONTH
... well, you get the picture.
2. Unintended data:
Depending on the particular version of SQL Server, and column datatypes, using BETWEEN
(or similar inclusive upper-bound ranges: <=
) can result in the wrong data being selected. Essentially, you potentially end up including data from midnight of the "next" day, or excluding some portion of the "current" day's records.
What you should be doing:
So we need a way that's safe for our data, and will use indices (if viable). The correct way is then of the form:
WHERE date_created >= @startOfPreviousMonth AND date_created < @startOfCurrentMonth
Given that there's only one month, @startOfPreviousMonth
can be easily substituted for/derived by:
DATEADD(month, -1, @startOCurrentfMonth)
If you need to derive the start-of-current-month in the server, you can do it via the following:
DATEADD(month, DATEDIFF(month, 0, CURRENT_TIMESTAMP), 0)
A quick word of explanation here. The initial DATEDIFF(...)
will get the difference between the start of the current era (0001-01-01
- AD, CE, whatever), essentially returning a large integer. This is the count of months to the start of the current month. We then add this number to the start of the era, which is at the start of the given month.
So your full script could/should look similar to the following:
DECLARE @startOfCurrentMonth DATETIME
SET @startOfCurrentMonth = DATEADD(month, DATEDIFF(month, 0, CURRENT_TIMESTAMP), 0)
SELECT *
FROM Member
WHERE date_created >= DATEADD(month, -1, @startOfCurrentMonth) -- this was originally misspelled
AND date_created < @startOfCurrentMonth
All date operations are thus only performed once, on one value; the optimizer is free to use indices, and no incorrect data will be included.
I had a similar issue, which made me write my own plugin for this. Have a look at jquery-quickfit (which is quite similar to Robert Koritnik's solution, which I really like).
In order to prevent the headline to span multiple lines, just add a css style of:
white-space:nowrap;
to the element.
After including jquery and quickfit in the header. You can trigger quickfit with:
$('h1').quickfit();
It meassures and calculates a size invariant meassure for each letter of the text to fit and uses this to calculate the next best font-size which fits the text into the container.
The calculations are cached, which makes it very fast when dealing having to fit multiple text or having to fit a text multiple times, like e.g., on window resize (there is almost no performance penalty on resize).
Demo for a similar situation as yours
Further documentation, examples and source code are on the project page.
If you right click on any result of "Edit Top 200 Rows" query in SSMS you will see the option "Pane -> SQL". It then shows the SQL Query that was run, which you can edit as you wish.
In SMSS 2012 and 2008, you can use Ctrl+3 to quickly get there.
UPDATE:
Upon learning flex recently, there is a cleaner way (no tables and less css). Set the wrapper as display: flex;
and to center it's children give it the properties align-items: center;
for (vertical) and justify-content: center;
(horizontal) centering.
See this updated JS Fiddle
Strange that nobody suggested this before.. I always use tables to do this.
Simply make a wrapper have display: table
and center stuff inside it with text-align: center
for horizontal and vertical-align: middle
for vertical alignment.
<div class='wrapper'>
<i class='icon fa fa-bars'></i>
</div>
and some sass like this
.wrapper{
display: table;
i{
display: table-cell;
vertical-align: middle;
text-align: center;
}
}
or see this JS Fiddle
Every class or interface can be used as a type in TypeScript.
const date = new Date();
will already know about the date
type definition as Date
is an internal TypeScript object referenced by the DateConstructor interface.
And for the constructor you used, it is defined as:
interface DateConstructor {
new(): Date;
...
}
To make it more explicit, you can use:
const date: Date = new Date();
You might be missing the type definitions though, the Date
is coming for my example from the ES6 lib, and in my tsconfig.json
I have defined:
"compilerOptions": {
"target": "ES6",
"lib": [
"es6",
"dom"
],

Quick guide:
Download Google USB Driver
Connect your device with Android Debugging enabled to your PC
Open Device Manager of Windows from System Properties.
Your device should appear under Other devices
listed as something like
Android ADB Interface
or 'Android Phone' or similar. Right-click that and
click on Update Driver Software...
Select Browse my computer for driver software
Select Let me pick from a list of device drivers on my computer
Double-click Show all devices
Press the Have disk
button
Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf
Select Android ADB Interface
from the list of device types.
Press the Yes
button
Press the Install
button
Press the Close
button
Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.
Are you using a shared hosting provider? It could be master settings overriding anything you're trying to change. Have you tried adding those into your .htaccess?

This seems to be the supported native method in OS X:
cd /Applications/eclipse/
open -n Eclipse.app
Be sure to specify the ".app" version (directory); in OS X Mountain Lion erroneously using the symbolic link such as open -n eclipse
, might get one GateKeeper stopping access:
"eclipse" can't be opened because it is from an unidentified developer.
Your security preferences allow installation of only apps from the Mac App Store and identified developers.
Even removing the extended attribute com.apple.quarantine
does not fix that. Instead, simply using the ".app" version will rely on your previous consent, or prompt you once:
"Eclipse" is an application downloaded from the Internet. Are you sure you want to open it?
With the help of ProgrammersBlock posts I came up with this. My needs were slightly different. I needed to take a string and return it as a LocalDate object. I was handed code that was using the older Calendar and SimpleDateFormat. I wanted to make it a little more current. This is what I came up with.
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
void ExampleFormatDate() {
LocalDate formattedDate = null; //Declare LocalDate variable to receive the formatted date.
DateTimeFormatter dateTimeFormatter; //Declare date formatter
String rawDate = "2000-01-01"; //Test string that holds a date to format and parse.
dateTimeFormatter = DateTimeFormatter.ISO_LOCAL_DATE;
//formattedDate.parse(String string) wraps the String.format(String string, DateTimeFormatter format) method.
//First, the rawDate string is formatted according to DateTimeFormatter. Second, that formatted string is parsed into
//the LocalDate formattedDate object.
formattedDate = formattedDate.parse(String.format(rawDate, dateTimeFormatter));
}
Hopefully this will help someone, if anyone sees a better way of doing this task please add your input.
Use
ls | % {(get-date) - $_.LastWriteTime }
It can work to retrieve the diff. You can replace ls
with a single file.
You could also look with a
netstat -abn
It gives the ports with the corresponding application that keeps them open.
Edit: or TCPView.
You should use Array.reduce
for this.
var options = [_x000D_
{ name: 'One', assigned: true }, _x000D_
{ name: 'Two', assigned: false }, _x000D_
{ name: 'Three', assigned: true }, _x000D_
];_x000D_
_x000D_
var reduced = options.reduce(function(filtered, option) {_x000D_
if (option.assigned) {_x000D_
var someNewValue = { name: option.name, newProperty: 'Foo' }_x000D_
filtered.push(someNewValue);_x000D_
}_x000D_
return filtered;_x000D_
}, []);_x000D_
_x000D_
document.getElementById('output').innerHTML = JSON.stringify(reduced);
_x000D_
<h1>Only assigned options</h1>_x000D_
<pre id="output"> </pre>
_x000D_
Alternatively, the reducer can be a pure function, like this
var reduced = options.reduce(function(result, option) {
if (option.assigned) {
return result.concat({
name: option.name,
newProperty: 'Foo'
});
}
return result;
}, []);
It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?
Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:
UPDATE INVOICE
SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
, INV_TOTAL = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)
WHERE INV_ID = I_INV_ID;
Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.
class enum.Enum
is a class that solves all your enumeration needs, so you just need to inherit from it, and add your own fields. Then from then on, all you need to do is to just call it's attributes: name
& value
:
from enum import Enum
class Letter(Enum):
A = 1
B = 2
C = 3
print({i.name: i.value for i in Letter})
# prints {'A': 1, 'B': 2, 'C': 3}
$('#form').keydown(function(e){
if (e.keyCode === 13) { // If Enter key pressed
$(this).trigger('submit');
}
});
I would just do
int pnSize = primeNumber.size();
for (int i = 0; i < pnSize; i++)
cout << primeNumber[i] << ' ';
function isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
The (A==B).all()
solution is very neat, but there are some built-in functions for this task. Namely array_equal
, allclose
and array_equiv
.
(Although, some quick testing with timeit
seems to indicate that the (A==B).all()
method is the fastest, which is a little peculiar, given it has to allocate a whole new array.)
This works:
myWindow = window.open('http://www.yahoo.com','myWindow', "width=200, height=200");
Try [attr.style]="changeBackground()"
If it's not a big/long array just mirror it:
for( int i = 0; i < arr.length/2; ++i )
{
temp = arr[i];
arr[i] = arr[arr.length - i - 1];
arr[arr.length - i - 1] = temp;
}
I wrote a module that can do this, called BFJ. Specifically, the method bfj.match
can be used to break up a large stream into discrete chunks of JSON:
const bfj = require('bfj');
const fs = require('fs');
const stream = fs.createReadStream(filePath);
bfj.match(stream, (key, value, depth) => depth === 0, { ndjson: true })
.on('data', object => {
// do whatever you need to do with object
})
.on('dataError', error => {
// a syntax error was found in the JSON
})
.on('error', error => {
// some kind of operational error occurred
})
.on('end', error => {
// finished processing the stream
});
Here, bfj.match
returns a readable, object-mode stream that will receive the parsed data items, and is passed 3 arguments:
A readable stream containing the input JSON.
A predicate that indicates which items from the parsed JSON will be pushed to the result stream.
An options object indicating that the input is newline-delimited JSON (this is to process format B from the question, it's not required for format A).
Upon being called, bfj.match
will parse JSON from the input stream depth-first, calling the predicate with each value to determine whether or not to push that item to the result stream. The predicate is passed three arguments:
The property key or array index (this will be undefined
for top-level items).
The value itself.
The depth of the item in the JSON structure (zero for top-level items).
Of course a more complex predicate can also be used as necessary according to requirements. You can also pass a string or a regular expression instead of a predicate function, if you want to perform simple matches against property keys.
You have no need to do your User
class being IDisposable
since the class doesn't acquire any non-managed resources (file, database connection, etc.). Usually, we mark classes as
IDisposable
if they have at least one IDisposable
field or/and property.
When implementing IDisposable
, better put it according Microsoft typical scheme:
public class User: IDisposable {
...
protected virtual void Dispose(Boolean disposing) {
if (disposing) {
// There's no need to set zero empty values to fields
// id = 0;
// name = String.Empty;
// pass = String.Empty;
//TODO: free your true resources here (usually IDisposable fields)
}
}
public void Dispose() {
Dispose(true);
GC.SuppressFinalize(this);
}
}
JSONArray jsonArray = new JSONArray();
for (loop) {
JSONObject jsonObj= new JSONObject();
jsonObj.put("srcOfPhoto", srcOfPhoto);
jsonObj.put("username", "name"+count);
jsonObj.put("userid", "userid"+count);
jsonArray.put(jsonObj.valueToString());
}
JSONObject parameters = new JSONObject();
parameters.put("action", "remove");
parameters.put("datatable", jsonArray );
parameters.put(Constant.MSG_TYPE , Constant.SUCCESS);
Why were you using an Hashmap if what you wanted was to put it into a JSONObject?
EDIT: As per http://www.json.org/javadoc/org/json/JSONArray.html
EDIT2: On the JSONObject method used, I'm following the code available at: https://github.com/stleary/JSON-java/blob/master/JSONObject.java#L2327 , that method is not deprecated.
We're storing a string representation of the JSONObject, not the JSONObject itself
Yes, there is one here: http://en.wikipedia.org/wiki/Byte_order_mark#Representations_of_byte_order_marks_by_encoding.
I solved this by looking at this comment on JBIDE-11655 : deleting all .project, .settings and .classpath in my projects folder.
Netflix also implements this feature
(function() {
try {
var $_console$$ = console;
Object.defineProperty(window, "console", {
get: function() {
if ($_console$$._commandLineAPI)
throw "Sorry, for security reasons, the script console is deactivated on netflix.com";
return $_console$$
},
set: function($val$$) {
$_console$$ = $val$$
}
})
} catch ($ignore$$) {
}
})();
They just override console._commandLineAPI
to throw security error.
"Why do i get that error?" - probably, you don't have "using System.Collections;
" at the top of the file - only "using System.Collections.Generic;
" - however, generics are probably safer - see below:
static bool ArraysEqual<T>(T[] a1, T[] a2)
{
if (ReferenceEquals(a1,a2))
return true;
if (a1 == null || a2 == null)
return false;
if (a1.Length != a2.Length)
return false;
EqualityComparer<T> comparer = EqualityComparer<T>.Default;
for (int i = 0; i < a1.Length; i++)
{
if (!comparer.Equals(a1[i], a2[i])) return false;
}
return true;
}
As stated in Android's Support Library Overview, it is considered good practice to include the support library by default because of the large diversity of devices and the fragmentation that exists between the different versions of Android (and thus, of the provided APIs).
This is the reason why Android code templates tools included in Eclipse through the Android Development Tools (ADT)
integrate them by default.
I noted that you target API 15
in your sample, but the miminum required SDK for your package is API 10
, for which the compatibility libraries can provide a tremendous amount of backward compatible APIs. An example would be the ability of using the Fragment API
which appeard on API 11
(Android 3.0 Honeycomb) on a device that runs an older version of this system.
It is also to be noted that you can deactivate automatic inclusion of the Support Library by default.
public static string AppRootDirectory()
{
string _BaseDirectory = AppDomain.CurrentDomain.BaseDirectory;
return Path.GetFullPath(Path.Combine(_BaseDirectory, @"..\..\"));
}
You can assign it to a hidden field, and retrieve it using
var value= Request.Form["value"]
If you have a huge data-set, then you can use an easy but faster(execution time) way of doing this using swifter:
import pandas as pd
import swifter
def fnc(m,x,c):
return m*x+c
df = pd.DataFrame({"m": [1,2,3,4,5,6], "c": [1,1,1,1,1,1], "x":[5,3,6,2,6,1]})
df["y"] = df.swifter.apply(lambda x: fnc(x.m, x.x, x.c), axis=1)
Switch to Branch2
git checkout Branch2
Apply the current (Branch2) changes on top of the Branch1 changes, staying in Branch2:
git rebase Branch1
Which would leave you with the desired result in Branch2:
a -- b -- c <-- Master
\
d -- e <-- Branch1
\
d -- e -- f' -- g' <-- Branch2
You can delete Branch1.
You need to have org/name
dirs at /usr/share/stuff
and place your org.name
package sources at this dir.
In this part of your SP:
IF @DateFirst <> '' and @DateLast <> ''
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + @DateFirst
+ ' and convert (Date,DateLog) <=''' + @DateLast
you are trying to concatenate strings and datetimes.
As the datetime
type has higher priority than varchar
/nvarchar
, the +
operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= '''
and others) to datetime or numeric values. And fails.
That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.
To amend the situation, you need to add explicit casting of your datetime variables to strings:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst)
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)
You'll also need to add closing single quotes:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst) + ''''
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''
this is a good method:
git tag -l | xargs git tag -d && git fetch -t

Example groupBy and sum of a column using Lodash 4.17.4
var data = [{
"name": "jim",
"color": "blue",
"amount": 22
}, {
"name": "Sam",
"color": "blue",
"amount": 33
}, {
"name": "eddie",
"color": "green",
"amount": 77
}];
var result = _(data)
.groupBy(x => x.color)
.map((value, key) =>
({color: key,
totalamount: _.sumBy(value,'amount'),
users: value})).value();
console.log(result);
Say you have a list such as:
a = [9,8,7]
The following two methods are pretty compact ways to get a tuple with the minimum element and its index. Both take a similar time to process. I better like the zip method, but that is my taste.
element, index = min(list(zip(a, range(len(a)))))
min(list(zip(a, range(len(a)))))
(7, 2)
timeit min(list(zip(a, range(len(a)))))
1.36 µs ± 107 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
index, element = min(list(enumerate(a)), key=lambda x:x[1])
min(list(enumerate(a)), key=lambda x:x[1])
(2, 7)
timeit min(list(enumerate(a)), key=lambda x:x[1])
1.45 µs ± 78.1 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
You can do it with a pivot
query, like this:
select * from (
select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
from my_table t
)
pivot
(
MIN(DOCUMENT_ID)
for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.
It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.
Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart
and touchmove
handlers, which may prevent the scroll entirely by calling preventDefault()
on the event.
Solution: {passive: true}
By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault
to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user
.
document.addEventListener("touchstart", function(e) {
console.log(e.defaultPrevented); // will be false
e.preventDefault(); // does nothing since the listener is passive
console.log(e.defaultPrevented); // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);
For others who are experiencing with the same problem, here is the description of the bug in php + patch https://bugs.php.net/bug.php?id=44522
Swift 3
When you make the @IBAction:
@IBAction func btnAction(_ sender: UIButton) {
sender.setTitle("string goes here", for: .normal)
}
This sets the sender as UIButton (instead of Any) so it targets the btnAction as a UIButton
MVC, MVP, MVVM
MVC (old one)
MVP (more modular because of its low-coupling. Presenter is a mediator between the View and Model)
MVVM (You already have two-way binding between VM and UI component, so it is more automated than MVP)
To allow a nullable Amount
field, just use the null coalescing operator to convert nulls to 0.
var creditsSum = (from u in context.User
join ch in context.CreditHistory on u.ID equals ch.UserID
where u.ID == userID
select ch.Amount ?? 0).Sum();
UPDATE dummy SET myfield=1 WHERE id>1;

and to insert data use the following
$sql = "INSERT INTO Table-Name (Column-Name)

what about changing the position: relative on your #content #text div to position: absolute
#content #text {
position:absolute;
width:950px;
height:215px;
color:red;
}
then you can use the css properties left and top to position within the #content div
SVG would be easier for you, since selection and moving it around is already built in. SVG objects are DOM objects, so they have "click" handlers, etc.
DIVs are okay but clunky and have awful performance loading at large numbers.
Canvas has the best performance hands-down, but you have to implement all concepts of managed state (object selection, etc) yourself, or use a library.
HTML5 Canvas is simply a drawing surface for a bit-map. You set up to draw (Say with a color and line thickness), draw that thing, and then the Canvas has no knowledge of that thing: It doesn't know where it is or what it is that you've just drawn, it's just pixels. If you want to draw rectangles and have them move around or be selectable then you have to code all of that from scratch, including the code to remember that you drew them.
SVG on the other hand must maintain references to each object that it renders. Every SVG/VML element you create is a real element in the DOM. By default this allows you to keep much better track of the elements you create and makes dealing with things like mouse events easier by default, but it slows down significantly when there are a large number of objects
Those SVG DOM references mean that some of the footwork of dealing with the things you draw is done for you. And SVG is faster when rendering really large objects, but slower when rendering many objects.
A game would probably be faster in Canvas. A huge map program would probably be faster in SVG. If you do want to use Canvas, I have some tutorials on getting movable objects up and running here.
Canvas would be better for faster things and heavy bitmap manipulation (like animation), but will take more code if you want lots of interactivity.
I've run a bunch of numbers on HTML DIV-made drawing versus Canvas-made drawing. I could make a huge post about the benefits of each, but I will give some of the relevant results of my tests to consider for your specific application:
I made Canvas and HTML DIV test pages, both had movable "nodes." Canvas nodes were objects I created and kept track of in Javascript. HTML nodes were movable Divs.
I added 100,000 nodes to each of my two tests. They performed quite differently:
The HTML test tab took forever to load (timed at slightly under 5 minutes, chrome asked to kill the page the first time). Chrome's task manager says that tab is taking up 168MB. It takes up 12-13% CPU time when I am looking at it, 0% when I am not looking.
The Canvas tab loaded in one second and takes up 30MB. It also takes up 13% of CPU time all of the time, regardless of whether or not one is looking at it. (2013 edit: They've mostly fixed that)
Dragging on the HTML page is smoother, which is expected by the design, since the current setup is to redraw EVERYTHING every 30 milliseconds in the Canvas test. There are plenty of optimizations to be had for Canvas for this. (canvas invalidation being the easiest, also clipping regions, selective redrawing, etc.. just depends on how much you feel like implementing)
There is no doubt you could get Canvas to be faster at object manipulation as the divs in that simple test, and of course far faster in the load time. Drawing/loading is faster in Canvas and has far more room for optimizations, too (ie, excluding things that are off-screen is very easy).
Maybe something like this:
import matplotlib.pyplot
import pylab
x = [1,2,3,4]
y = [3,4,8,6]
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
EDIT:
Let me see if I understand you correctly now:
You have:
test1 | test2 | test3
test3 | 1 | 0 | 1
test4 | 0 | 1 | 0
test5 | 1 | 1 | 0
Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.
Let's say you results are stored in a 2-D list:
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
We want to transform them into two variables so we are able to plot them.
And I believe this code will give you what you are looking for:
import matplotlib
import pylab
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
x = []
y = []
for ind_1, sublist in enumerate(results):
for ind_2, ele in enumerate(sublist):
if ele == 1:
x.append(ind_1)
y.append(ind_2)
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
Notice that I do need to import pylab
, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.
I am using eclipse kepler 4.3, PyDev 3.9.2 and on my ubuntu 14.04 I encountered with the same problem. I tried and spent hours, with all the above most of the options but in vain. Then I tried the following which was great:
And I was using Python 2.7 as an interpreter, although it doesn’t effect, I think.
I also have the situation that I have a set of documents to be crawled. I start with an initial "seed" document which should be processed, that document contains links to other documents which should also be processed, and so on.
In my main program, I just want to write something like the following, where Crawler
controls a bunch of threads.
Crawler c = new Crawler();
c.schedule(seedDocument);
c.waitUntilCompletion()
The same situation would happen if I wanted to navigate a tree; i would pop in the root node, the processor for each node would add children to the queue as necessary, and a bunch of threads would process all the nodes in the tree, until there were no more.
I couldn't find anything in the JVM which I thought was a bit surprising. So I wrote a class ThreadPool
which one can either use directly or subclass to add methods suitable for the domain, e.g. schedule(Document)
. Hope it helps!
If your reason for iterating trough the Map
, is to do an operation on the value and write to a resulting Map
. I recommend using the transform
-methods in the Google Guava Maps
class.
import com.google.common.collect.Maps;
After you have added the Maps
to your imports, you can use Maps.transformValues
and Maps.transformEntries
on your maps, like this:
public void transformMap(){
Map<String, Integer> map = new HashMap<>();
map.put("a", 2);
map.put("b", 4);
Map<String, Integer> result = Maps.transformValues(map, num -> num * 2);
result.forEach((key, val) -> print(key, Integer.toString(val)));
// key=a,value=4
// key=b,value=8
Map<String, String> result2 = Maps.transformEntries(map, (key, value) -> value + "[" + key + "]");
result2.forEach(this::print);
// key=a,value=2[a]
// key=b,value=4[b]
}
private void print(String key, String val){
System.out.println("key=" + key + ",value=" + val);
}
.val()
always works with textarea
elements.
.text()
works sometimes and fails other times! It's not reliable (tested in Chrome 33)
What's best is that .val()
works seamlessly with other form elements too (like input
) whereas .text()
fails.
The server sends the following in its response header to set a cookie field.
Set-Cookie:
name=
value
If there is a cookie set, then the browser sends the following in its request header.
Cookie:
name=
value
See the HTTP Cookie article at Wikipedia for more information.
Why don't you simply try
System.out.println(1500/1000.0);
System.out.println(500/1000.0);
This happened to me when I pulled down my repo after moving it to a new location. The solution was to unload and then reload each project that was showing this error.
I tried a few other options but nothing worked for me. Also in this situation my config files were set to use languageversion 6, so setting them to default did not fix the issue.
You don't apply a binary mask to an image. You (optionally) use a binary mask in a processing function call to tell the function which pixels of the image you want to process. If I'm completely misinterpreting your question, you should add more detail to clarify.
Since most of the autocomplete
suggestions, including the accepted answer, don't work in today's web browsers (i.e. web browser password managers ignore autocomplete
), a more novel solution is to swap between password
and text
types and make the background color match the text color when the field is a plain text field, which continues to hide the password while being a real password field when the user (or a program like KeePass) is entering a password. Browsers don't ask to save passwords that are stored in plain text fields.
The advantage of this approach is that it allows for progressive enhancement and therefore doesn't require Javascript for a field to function as a normal password field (you could also start with a plain text field instead and apply the same approach but that's not really HIPAA PHI/PII-compliant). Nor does this approach depend on hidden forms/fields which might not necessarily be sent to the server (because they are hidden) and some of those tricks also don't work either in several modern browsers.
jQuery plugin:
Relevant source code from the above link:
(function($) {
$.fn.StopPasswordManager = function() {
return this.each(function() {
var $this = $(this);
$this.addClass('no-print');
$this.attr('data-background-color', $this.css('background-color'));
$this.css('background-color', $this.css('color'));
$this.attr('type', 'text');
$this.attr('autocomplete', 'off');
$this.focus(function() {
$this.attr('type', 'password');
$this.css('background-color', $this.attr('data-background-color'));
});
$this.blur(function() {
$this.css('background-color', $this.css('color'));
$this.attr('type', 'text');
$this[0].selectionStart = $this[0].selectionEnd;
});
$this.on('keydown', function(e) {
if (e.keyCode == 13)
{
$this.css('background-color', $this.css('color'));
$this.attr('type', 'text');
$this[0].selectionStart = $this[0].selectionEnd;
}
});
});
}
}(jQuery));

Click "Add Entry" in the menu and then scroll to the bottom of the page to "Module: Stop Password Manager".
Disclaimer: While this approach works for sighted individuals, there might be issues with screen reader software. For example, a screen reader might read the user's password out loud because it sees a plain text field. There might also be other unforeseen consequences of using the above plugin. Altering built-in web browser functionality should be done sparingly with testing a wide variety of conditions and edge cases.
All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)
Based on this related answer, you are looking at a list that looks like: A-Z
, a-z
, 0-9
, -
, .
, _
, ~
, :
, /
, ?
, #
, [
, ]
, @
, !
, $
, &
, '
, (
, )
, *
, +
, ,
, ;
, %
, and =
. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. %
can only be used in conjunction with url encoding as in %20
), the RFC has all of these specifics.
You could do $stmt->queryString
to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.
Get rid of the this statements too
var img = document.createElement("img");
img.src = "img/eqp/"+this.apparel+"/"+this.facing+"_idle.png";
src = document.getElementById("gamediv");
src.appendChild(this.img)
I tried the suggestion to remove and re-add the project, but then fixing up dependencies can be a pain.
I use this approach:
I've tried everything but nothing worked, but this did. If you can debug on local IIS instead of Express, change the configurations as shown in the image below. Do not forget to click on "Create virtual directory"
We are also getting the same error while we are trying to access a same resource with in milliseconds. Like if i try to POST
some data to www.abc.com/blog
and with in milliseconds an other request will also go for the same resource i.e. www.abc.com/blog
from the same user. So it'll give the 409
error.

There are precious few immutable collections in the current framework. I can think of one relatively pain-free option in .NET 3.5:
Use Enumerable.ToLookup()
- the Lookup<,>
class is immutable (but multi-valued on the rhs); you can do this from a Dictionary<,>
quite easily:
Dictionary<string, int> ids = new Dictionary<string, int> {
{"abc",1}, {"def",2}, {"ghi",3}
};
ILookup<string, int> lookup = ids.ToLookup(x => x.Key, x => x.Value);
int i = lookup["def"].Single();

I know this is old. I just wanted to dump this here for anyone that was looking for an answer to getting a domain name. This is in coordination with Peter's answer. There "is" a bug as stated by Rich. But, you can always make a simple workaround for that. The way I can tell if they are still on the domain or not is by pinging the domain name. If it responds, continue on with whatever it was that I needed the domain for. If it fails, I drop out and go into "offline" mode. Simple string method.
string GetDomainName()
{
string _domain = IPGlobalProperties.GetIPGlobalProperties().DomainName;
Ping ping = new Ping();
try
{
PingReply reply = ping.Send(_domain);
if (reply.Status == IPStatus.Success)
{
return _domain;
}
else
{
return reply.Status.ToString();
}
}
catch (PingException pExp)
{
if (pExp.InnerException.ToString() == "No such host is known")
{
return "Network not detected!";
}
return "Ping Exception";
}
}
Recently,I'm learning Wordpress,it provide a class WP_QUERY to operate the database. You can insert array or object to the database.I feel it is amazing,so I go to see how to achieve it.Maybe,some ideas you can get from it.The main function is: apply_filters.
apply_filters( $tag, $value, $key);
you can ignore the first parameter ,treat the second parameter as array,what the function do is sanitizing the array into string.
after inserting into the database,you can see this :
key s:12:"focal_length";s:3:"190";s:3:"iso";s:3:"400";s:13:"shutter_speed";s:6:"0.0004";s:5:"title";s:0:"";}}
I had a similar issue where the tests where not being discovered. I had the correct version of NUnit, versions matched up between NUnit and adapter, and the tests where tagged correctly. I was running VS 2017 Enterprise not as an administrator. After starting VS as administrator the tests appeared.
You can group your specific layout under the correct folder structure as follows.
layout-land-target_version
ie
layout-land-19 // target KitKat
likewise you can create your layouts.
Hope this will help you
You can print a native linebreak using the standard os
library
import os
with open('test.txt','w') as f:
f.write(os.linesep)
It's a reference to the current object, it's most commonly used in object oriented code.
Example:
<?php
class Person {
public $name;
function __construct( $name ) {
$this->name = $name;
}
};
$jack = new Person('Jack');
echo $jack->name;
This stores the 'Jack' string as a property of the object created.
The Lazy way (which will cause future designers to curse your name and murder you in your sleep):
#myelement

Disclaimer: I do not advocate this approach, but it certainly is the lazy way.

Suppose we want to pass three values(u1,u2,u3) from say 'show.jsp' to another page say 'display.jsp' Make three hidden text boxes and a button that is click automatically(using javascript). //Code to written in 'show.jsp'
<body>
<form action="display.jsp" method="post">
<input type="hidden" name="u1" value="<%=u1%>"/>
<input type="hidden" name="u2" value="<%=u2%>" />
<input type="hidden" name="u3" value="<%=u3%>" />
<button type="hidden" id="qq" value="Login" style="display: none;"></button>
</form>
<script type="text/javascript">
document.getElementById("qq").click();
</script>
</body>
// Code to be written in 'display.jsp'
<% String u1 = request.getParameter("u1").toString();
String u2 = request.getParameter("u2").toString();
String u3 = request.getParameter("u3").toString();
%>
If you want to use these variables of servlets in javascript then simply write
<script type="text/javascript">
var a=<%=u1%>;
</script>
Hope it helps :)
The user "geoand" is right in pointing out the reasons here and giving a solution. But a better approach is to encapsulate your configuration into a separate class, say SystemContiguration java class and then inject this class into what ever services you want to use those fields.
Your current way(@grahamrb) of reading config values directly into services is error prone and would cause refactoring headaches if config setting name is changed.
You generally want to ignore the SIGPIPE
and handle the error directly in your code. This is because signal handlers in C have many restrictions on what they can do.
The most portable way to do this is to set the SIGPIPE
handler to SIG_IGN
. This will prevent any socket or pipe write from causing a SIGPIPE
signal.
To ignore the SIGPIPE
signal, use the following code:
signal(SIGPIPE, SIG_IGN);
If you're using the send()
call, another option is to use the MSG_NOSIGNAL
option, which will turn the SIGPIPE
behavior off on a per call basis. Note that not all operating systems support the MSG_NOSIGNAL
flag.
Lastly, you may also want to consider the SO_SIGNOPIPE
socket flag that can be set with setsockopt()
on some operating systems. This will prevent SIGPIPE
from being caused by writes just to the sockets it is set on.
Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000
or Access-Control-Allow-Origin: *
on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true
on the POST response as well.
Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept
to match the requested header.
I think you should use mvn install:install-file
to populate your local repository with the library jars then you should change the scope from system to compile.
If you are starting with maven I suggest to use maven directly not IDE plugins as it adds an extra layer of complexity.
As for the error, do you put the required jars on your classpath? If you are using types from the library, you need to have access to it in the runtime as well. This has nothing to do with maven itself.
I don't understand why you want to put the library to source control - it is for sources code not binary jars.
Please let me know if it is not easy:

Bitmap is Parcelable so you can add using [putExtra(String,Parcelable)][2] method, But not sure it is a best practice, If it is large size data it is better to store in a single place and use from both activities.

Use the builtin function zip()
:
In Python 3:
z = list(zip(x,y))
In Python 2:
z = zip(x,y)
This page on string::string
gives two potential constructors that would do what you want:
string ( const char * s, size_t n );
string ( const string& str, size_t pos, size_t n = npos );
Example:
#include<cstdlib>
#include<cstring>
#include<string>
#include<iostream>
using namespace std;
int main(){
char* p= (char*)calloc(30, sizeof(char));
strcpy(p, "Hello world");
string s(p, 15);
cout << s.size() << ":[" << s << "]" << endl;
string t(p, 0, 15);
cout << t.size() << ":[" << t << "]" << endl;
free(p);
return 0;
}
Output:
15:[Hello world]
11:[Hello world]
The first form considers p
to be a simple array, and so will create (in our case) a string of length 15, which however prints as a 11-character null-terminated string with cout << ...
. Probably not what you're looking for.
The second form will implicitly convert the char*
to a string, and then keep the maximum between its length and the n
you specify. I think this is the simplest solution, in terms of what you have to write.
Update user table in mysql DB. And set some password where it is blank, i was using root user so i set password for root user.
update mysql.user set password = PASSWORD('123456') where password = '';
flush privileges;
And then again tried from ATG CIM by providing password and it worked fine.

- indicates that a trigger starts a task when a user logs on.
-AtStartup
- indicates that a trigger starts a task when the system is started.
-WindowStyle Hidden
- don't show PowerShell window at startup. Remove if not required.
-RunLevel Highest
- run PowerShell as administrator. Remove if not required.
P.S.
If necessary execute PowerShell command below to enable PowerShell scripts execution.
Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy Unrestricted -Force;
Bypass
- nothing is blocked and there are no warnings or prompts.
Unrestricted
- loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the internet, you're prompted for permission before it runs.
I'm not sure if you can turn it off, but you can change the colors of it :)
myDiv::selection,
myDiv::-moz-selection,
myDiv::-webkit-selection {
background:#000;
color:#fff;
}
Then just match the colors to your "darky" design and see what happens :)
You can also use CopyTo:
var ms = new MemoryStream();
yourStreamReader.BaseStream.CopyTo(ms); // blocking call till the end of the stream
ms.GetBuffer().CopyTo(yourArray, ms.Length);
or
var ms = new MemoryStream();
var ct = yourStreamReader.BaseStream.CopyToAsync(ms);
await ct;
ms.GetBuffer().CopyTo(yourArray, ms.Length);
Subscribing what basil said in a comment to the question itself, if method = RequestMethod.GET
you can use @RequestParam List<String> groupVal

Double parenthesis (( ... ))
is used for arithmetic operations.
Double square brackets [[ ... ]]
can be used to compare and examine numbers (only integers are supported), with the following operators:
· NUM1 -eq NUM2 returns true if NUM1 and NUM2 are numerically equal.
· NUM1 -ne NUM2 returns true if NUM1 and NUM2 are not numerically equal.
· NUM1 -gt NUM2 returns true if NUM1 is greater than NUM2.
· NUM1 -ge NUM2 returns true if NUM1 is greater than or equal to NUM2.
· NUM1 -lt NUM2 returns true if NUM1 is less than NUM2.
· NUM1 -le NUM2 returns true if NUM1 is less than or equal to NUM2.
For example
if [[ $age > 21 ]] # bad, > is a string comparison operator
if [ $age > 21 ] # bad, > is a redirection operator
if [[ $age -gt 21 ]] # okay, but fails if $age is not numeric
if (( $age > 21 )) # best, $ on age is optional

BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
System.out.println(line);

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload
instruction was immediately evaluated, and then the $
usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).
So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.
var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
console.log("script loaded :)");
onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);
For my needs, it works fine now. Hope this can help others :)
One more way to do this is:
git config remote.origin.url https://github.com/abc/abc.git
To see the existing URL just do:
git config remote.origin.url
Not need to change all config in file /opt/lampp/etc/extra/httpd-xampp.conf.
The only thing you need to change is the Require local
It's kinda obvious what Require local means so just change to Require all granted
Require all granted
Solution
from Require local
to Require all granted
There is no if-else, just if.

The most important thing here is wich user is using nginx then do you need specify it as well
in your nginx.conf
user www-data;
worker_processes 1;
location / {
root /usr/home/user/public_html;
index index.php index.html index.htm;
}
location ~ [^/]\.php(/|$) {

include fastcgi_params;
}
in your www.conf
listen.owner = www-data
listen.group = www-data
;listen.mode = 0660
in your case the user and group is "www" so just replace it.
It is possible using sun.misc.Unsafe
: see this great answer from @Peter Lawrey -> Is there a way to get a reference address?
Using its code for printAddresses() :
public static void printAddresses(String label, Object... objects) {
System.out.print(label + ": 0x");
long last = 0;
int offset = unsafe.arrayBaseOffset(objects.getClass());
int scale = unsafe.arrayIndexScale(objects.getClass());
switch (scale) {
case 4:
long factor = is64bit ? 8 : 1;
final long i1 = (unsafe.getInt(objects, offset) & 0xFFFFFFFFL) * factor;
System.out.print(Long.toHexString(i1));
last = i1;
for (int i = 1; i < objects.length; i++) {
final long i2 = (unsafe.getInt(objects, offset + i * 4) & 0xFFFFFFFFL) * factor;
if (i2 > last)
System.out.print(", +" + Long.toHexString(i2 - last));
else
System.out.print(", -" + Long.toHexString( last - i2));
last = i2;
}
break;
case 8:
throw new AssertionError("Not supported");
}
System.out.println();
}
I set up this test :
//hashcode
System.out.println("Hashcode : "+myObject.hashCode());
System.out.println("Hashcode : "+System.identityHashCode(myObject));
System.out.println("Hashcode (HEX) : "+Integer.toHexString(myObject.hashCode()));
//toString
System.out.println("toString : "+String.valueOf(myObject));
printAddresses("Address", myObject);
Here is the output :

MySettings settings = MySettings.Load();
Console.WriteLine("Current value of 'myInteger': " + settings.myInteger);
Console.WriteLine("Incrementing 'myInteger'...");
settings.myInteger++;
Console.WriteLine("Saving settings...");
settings.Save();
Console.WriteLine("Done.");
Console.ReadKey();
}
class MySettings : AppSettings<MySettings>
{
public string myString = "Hello World";
public int myInteger = 1;
}
}
public class AppSettings<T> where T : new()
{
private const string DEFAULT_FILENAME = "settings.json";
public void Save(string fileName = DEFAULT_FILENAME)
{
File.WriteAllText(fileName, (new JavaScriptSerializer()).Serialize(this));
}
public static void Save(T pSettings, string fileName = DEFAULT_FILENAME)
{
File.WriteAllText(fileName, (new JavaScriptSerializer()).Serialize(pSettings));
}
public static T Load(string fileName = DEFAULT_FILENAME)
{
T t = new T();
if(File.Exists(fileName))
t = (new JavaScriptSerializer()).Deserialize<T>(File.ReadAllText(fileName));
return t;
}
}

In my case it was due to wrong import of the @Test annotation
Make sure you are using the following import
import org.junit.jupiter.api.Test;
By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.
In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.
The client code must set the withCredentials
property on the XMLHttpRequest
to true
in order to give permission.
However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials
header. Responding with this header to true
means that the server allows cookies (or other user credentials) to be included on cross-origin requests.
You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.
Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).
static
means different things in different contexts.
You can declare a static variable in a C function. This variable is only visible in the function however it behaves like a global in that it is only initialized once and it retains its value. In this example, everytime you call foo()
it will print an increasing number. The static variable is initialized only once.
void foo ()
{
static int i = 0;
printf("%d", i); i++
}
Another use of static is when you implement a function or global variable in a .c file but don't want its symbol to be visible outside of the .obj
generated by the file. e.g.
static void foo() { ... }
Try this as a shortcut, not as a definitive solution (see comments):
<script type="text/javascript">
var ip = location.host;
alert(ip);
</script>
This solution cannot work in some scenarios but it can help for quick testing. Regards
This means the version of android of your avd is older than the version being used to compile the code
The other answers indicating using IsNumeric in the where clause are correct, as far as they go, but it's important to remember that it returns 1 if the value can be converted to any numeric type. As such, oddities such as "1d3" will make it through the filter.
If you need only values composed of digits, search for that explicitly:
SELECT column1 FROM table WHERE column1 not like '%[^0-9]%'
The above is filtering to reject any column which contains a non-digit character
Note that in any case, you're going to incur a table scan, indexes are useless for this sort of query.
Or add this part
<script type="text/javascript">
var mySpan = document.createElement("span");
mySpan.innerHTML = "This is my span!";
mySpan.style.color = "red";
document.body.appendChild(mySpan);
alert("Why does the span change after this alert? Not before?");
</script>
after the HTML, like:
<html>
<head>...</head>
<body>...</body>
<script type="text/javascript">
var mySpan = document.createElement("span");
mySpan.innerHTML = "This is my span!";
mySpan.style.color = "red";
document.body.appendChild(mySpan);
alert("Why does the span change after this alert? Not before?");
</script>
</html>
There are a few ways you can define constants in Kotlin,
Using companion object
companion object {
const val ITEM1 = "item1"
const val ITEM2 = "item2"
}
you can use above companion object block inside any class and define all your fields inside this block itself. But there is a problem with this approach, the documentation says,
even though the members of companion objects look like static members in other languages, at runtime those are still instance members of real objects, and can, for example, implement interfaces.
When you create your constants using companion object, and see the decompiled bytecode, you'll something like below,
ClassName.Companion Companion = ClassName.Companion.$$INSTANCE;
@NotNull
String ITEM1 = "item1";
@NotNull
String ITEM2 = "item2";
public static final class Companion {
@NotNull
private static final String ITEM1 = "item1";
@NotNull
public static final String ITEM2 = "item2";
// $FF: synthetic field
static final ClassName.Companion $$INSTANCE;
private Companion() {
}
static {
ClassName.Companion var0 = new ClassName.Companion();
$$INSTANCE = var0;
}
}
From here you can easily see what the documentation said, even though the members of companion objects look like static members in other languages, at runtime those are still instance members of real objects It's doing extra work than required.
Now comes another way, where we don't need to use companion object like below,
object ApiConstants {
val ITEM1: String = "item1"
}
Again if you see the decompiled version of the byte code of above snippet, you'll find something like this,
public final class ApiConstants {
private static final String ITEM1 = "item1";
public static final ApiConstants INSTANCE;
public final String getITEM1() {
return ITEM1;
}
private ApiConstants() {
}
static {
ApiConstants var0 = new ApiConstants();
INSTANCE = var0;
CONNECT_TIMEOUT = "item1";
}
}
Now if you see the above decompiled code, it's creating get method for each variable. This get method is not required at all.
To get rid of these get methods, you should use const before val like below,
object ApiConstants {
const val ITEM1: String = "item1"
}
Now if you see the decompiled code of above snippet, you'll find it easier to read as it does the least background conversion for your code.
public final class ApiConstants {
public static final String ITEM1 = "item1";
public static final ApiConstants INSTANCE;
private ApiConstants() {
}
static {
ApiConstants var0 = new ApiConstants();
INSTANCE = var0;
}
}
So this is the best way to create constants.
The format defined in RFC2617 is credentials = auth-scheme #auth-param
. So, in agreeing with fumanchu, I think the corrected authorization scheme would look like
Authorization: FIRE-TOKEN apikey="0PN5J17HBGZHT7JJ3X82", hash="frJIUN8DYpKDtOLCwo//yllqDzg="
Where FIRE-TOKEN
is the scheme and the two key-value pairs are the auth parameters. Though I believe the quotes are optional (from Apendix B of p7-auth-19)...
auth-param = token BWS "=" BWS ( token / quoted-string )
I believe this fits the latest standards, is already in use (see below), and provides a key-value format for simple extension (if you need additional parameters).
Some examples of this auth-param syntax can be seen here...

I'm using Version 4.0.2.15 with Build 15.21
For me I needed this:
UPDATE table_name SET column_name = REPLACE(column_name,"search str","replace str");
Putting t.column_name
in the first argument of replace
did not work.
I will show you some example
First I extract the text data from the data frame (twitter_df
) to process further as following
from nltk.tokenize import word_tokenize
tweetText = twitter_df['text']
Then to tokenize I use the following method
from nltk.tokenize import word_tokenize
tweetText = tweetText.apply(word_tokenize)
Then, to remove stop words,
from nltk.corpus import stopwords
nltk.download('stopwords')
stop_words = set(stopwords.words('english'))
tweetText = tweetText.apply(lambda x:[word for word in x if word not in stop_words])
tweetText.head()
I Think this will help you
I use this:
Math.round(Date.now() / 1000)
No need for new object creation (see doc Date.now())
class EnumStringToInt // to search for a string in enum
{
enum Numbers{one,two,hree};
static void Main()
{
Numbers num = Numbers.one; // converting enum to string
string str = num.ToString();
//Console.WriteLine(str);
string str1 = "four";
string[] getnames = (string[])Enum.GetNames(typeof(Numbers));
int[] getnum = (int[])Enum.GetValues(typeof(Numbers));
try
{
for (int i = 0; i <= getnum.Length; i++)
{
if (str1.Equals(getnames[i]))
{
Numbers num1 = (Numbers)Enum.Parse(typeof(Numbers), str1);
Console.WriteLine("string found:{0}", num1);
}
}
}
catch (Exception ex)
{
Console.WriteLine("Value not found!", ex);
}
}
}
