I'm late for the party but I hope that my response will help someone: You can do this in your Python script:
import sys, os
sys.path.append('/path/to/your/django/app')
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
from django.conf import settings
the rest of your stuff goes here ....
You can replace those in your Manifest application
tag:
<application
...
tools:replace="android:label, android:icon, android:theme"/>
and will work for you.
Explanation
Using such a dependency/library in your gradle
file which has those labels in its Manifest's application tag may produce this problem and replacing them in your Manifest
is the solution.
You can actually use C# generics for this to make it real easy:
var file = new List<string>(System.IO.File.ReadAllLines("C:\\path"));
file.RemoveAt(12);
File.WriteAllLines("C:\\path", file.ToArray());
You can find the aspnet_regiis in the following directory:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319
Go to the directory and run the command form there. I guess the path is missing in your PATH variable.
It is possible. Have a look at JSch.addIdentity(...)
This allows you to use key either as byte array or to read it from file.
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
public class UserAuthPubKey {
public static void main(String[] arg) {
try {
JSch jsch = new JSch();
String user = "tjill";
String host = "192.18.0.246";
int port = 10022;
String privateKey = ".ssh/id_rsa";
jsch.addIdentity(privateKey);
System.out.println("identity added ");
Session session = jsch.getSession(user, host, port);
System.out.println("session created.");
// disabling StrictHostKeyChecking may help to make connection but makes it insecure
// see http://stackoverflow.com/questions/30178936/jsch-sftp-security-with-session-setconfigstricthostkeychecking-no
//
// java.util.Properties config = new java.util.Properties();
// config.put("StrictHostKeyChecking", "no");
// session.setConfig(config);
session.connect();
System.out.println("session connected.....");
Channel channel = session.openChannel("sftp");
channel.setInputStream(System.in);
channel.setOutputStream(System.out);
channel.connect();
System.out.println("shell channel connected....");
ChannelSftp c = (ChannelSftp) channel;
String fileName = "test.txt";
c.put(fileName, "./in/");
c.exit();
System.out.println("done");
} catch (Exception e) {
System.err.println(e);
}
}
}

If you are on Ubuntu you don't need to write any other code except your Python file's code , Here are the Steps :-
Yes, from the moment on you establish a HTTPS connection everyting is secure. The query string (GET) as the POST is sent over SSL.
Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:
@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
val cacheFile = File(context.cacheDir, "splash_video")
try {
val inputStream = context.assets.open("splash_video")
val outputStream = FileOutputStream(cacheFile)
try {
inputStream.copyTo(outputStream)
} finally {
inputStream.close()
outputStream.close()
}
} catch (e: IOException) {
throw IOException("Could not open splash_video", e)
}
return cacheFile
}
Here is a situation where there is definitely a need for inheritance for static fields and methods:
abstract class Animal
{
protected static string[] legs;
static Animal() {
legs=new string[0];
}
public static void printLegs()
{
foreach (string leg in legs) {
print(leg);
}
}
}
class Human: Animal
{
static Human() {
legs=new string[] {"left leg", "right leg"};
}
}
class Dog: Animal
{
static Dog() {
legs=new string[] {"left foreleg", "right foreleg", "left hindleg", "right hindleg"};
}
}
public static void main() {
Dog.printLegs();
Human.printLegs();
}
//what is the output?
//does each subclass get its own copy of the array "legs"?

Other answers already pointed out that the representation of floating numbers is a thorny issue, to say the least.
Since you don't give enough context in your question, I cannot know if the decimal module can be useful for your needs:
http://docs.python.org/library/decimal.html
Among other things you can explicitly specify the precision that you wish to obtain (from the docs):
>>> getcontext().prec = 6
>>> Decimal('3.0')
Decimal('3.0')
>>> Decimal('3.1415926535')
Decimal('3.1415926535')
>>> Decimal('3.1415926535') + Decimal('2.7182818285')
Decimal('5.85987')
>>> getcontext().rounding = ROUND_UP
>>> Decimal('3.1415926535') + Decimal('2.7182818285')
Decimal('5.85988')
A simple example from my prompt (python 2.6):
>>> import decimal
>>> a = decimal.Decimal('10.000000001')
>>> a
Decimal('10.000000001')
>>> print a
10.000000001
>>> b = decimal.Decimal('10.00000000000000000000000000900000002')
>>> print b
10.00000000000000000000000000900000002
>>> print str(b)
10.00000000000000000000000000900000002
>>> len(str(b/decimal.Decimal('3.0')))
29
Maybe this can help? decimal is in python stdlib since 2.4, with additions in python 2.6.
Hope this helps, Francesco
A 'docker way' would be to use docker hub automated builds. The Repository Links feature will rebuild your container when an upstream container is rebuilt, and the Webhooks feature will send you a notification.
It looks like the webhooks are limited to HTTP POST calls. You'd need to set up a service to catch them, or maybe use one of the POST to email services out there.
I haven't looked into it, but the new Docker Universal Control Plane might have a feature for detecting updated containers and re-deploying.
function sample() {
alert("This is sample function");
}
$(function() {
$("#button").click(function() {
setTimeout(sample, 2000);
});
});
If you want to encapsulate sample()
there, wrap the whole thing in a self invoking function (function() { ... })()
.
Let's walk through a simple example: the factorial function implemented in C.
We start with the obvious recursive definition
unsigned fac(unsigned n)
{
if (n < 2) return 1;
return n * fac(n - 1);
}
A function ends with a tail call if the last operation before the function returns is another function call. If this call invokes the same function, it is tail-recursive.
Even though fac()
looks tail-recursive at first glance, it is not as what actually happens is
unsigned fac(unsigned n)
{
if (n < 2) return 1;
unsigned acc = fac(n - 1);
return n * acc;
}
ie the last operation is the multiplication and not the function call.
However, it's possible to rewrite fac()
to be tail-recursive by passing the accumulated value down the call chain as an additional argument and passing only the final result up again as the return value:
unsigned fac(unsigned n)
{
return fac_tailrec(1, n);
}
unsigned fac_tailrec(unsigned acc, unsigned n)
{
if (n < 2) return acc;
return fac_tailrec(n * acc, n - 1);
}
Now, why is this useful? Because we immediately return after the tail call, we can discard the previous stackframe before invoking the function in tail position, or, in case of recursive functions, reuse the stackframe as-is.
The tail-call optimization transforms our recursive code into
unsigned fac_tailrec(unsigned acc, unsigned n)
{
TOP:
if (n < 2) return acc;
acc = n * acc;
n = n - 1;
goto TOP;
}
This can be inlined into fac()
and we arrive at
unsigned fac(unsigned n)
{
unsigned acc = 1;
TOP:
if (n < 2) return acc;
acc = n * acc;
n = n - 1;
goto TOP;
}
which is equivalent to
unsigned fac(unsigned n)
{
unsigned acc = 1;
for (; n > 1; --n)
acc *= n;
return acc;
}
As we can see here, a sufficiently advanced optimizer can replace tail-recursion with iteration, which is far more efficient as you avoid function call overhead and only use a constant amount of stack space.
to change the object owner try the following
EXEC sp_changedbowner 'sa'
that however is not your problem, to see diagrams the Da Vinci Tools objects have to be created (you will see tables and procs that start with dt_) after that
It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.
First off you need to download and install ODP from this site http://www.oracle.com/technetwork/topics/dotnet/index-085163.html
After installation add a reference of the assembly Oracle.DataAccess.dll.
Your are good to go after this.
using System;
using Oracle.DataAccess.Client;
class OraTest
{
OracleConnection con;
void Connect()
{
con = new OracleConnection();
con.ConnectionString = "User Id=<username>;Password=<password>;Data Source=<datasource>";
con.Open();
Console.WriteLine("Connected to Oracle" + con.ServerVersion);
}
void Close()
{
con.Close();
con.Dispose();
}
static void Main()
{
OraTest ot= new OraTest();
ot.Connect();
ot.Close();
}
}
What you need is a date template filter.
e.g:
<td>Joined {{user.date_created|date:"F Y" }}<td>
This returns Joined December 2018
This answer is an update with a little more consideration for OOM and various other leaks.
Assumes you have a directory intended as the destination and a name String already defined.
File destination = new File(directory.getPath() + File.separatorChar + filename);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
source.compress(Bitmap.CompressFormat.PNG, 100, bytes);
FileOutputStream fo = null;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
} catch (IOException e) {
} finally {
try {
fo.close();
} catch (IOException e) {}
}
I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.
Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes
Yes:
>>> from collections import Counter
>>> x = Counter({'a':5, 'b':3, 'c':7})
Using the sorted keyword key and a lambda function:
>>> sorted(x.items(), key=lambda i: i[1])
[('b', 3), ('a', 5), ('c', 7)]
>>> sorted(x.items(), key=lambda i: i[1], reverse=True)
[('c', 7), ('a', 5), ('b', 3)]
This works for all dictionaries. However Counter
has a special function which already gives you the sorted items (from most frequent, to least frequent). It's called most_common()
:
>>> x.most_common()
[('c', 7), ('a', 5), ('b', 3)]
>>> list(reversed(x.most_common())) # in order of least to most
[('b', 3), ('a', 5), ('c', 7)]
You can also specify how many items you want to see:
>>> x.most_common(2) # specify number you want
[('c', 7), ('a', 5)]
Replacing forward(/) slash with backward(\) slash will do the job. The folder separator in Windows is \ not /
In Kotlin, you can use isDuplicateParentStateEnabled = true
before the View
is added to the ViewGroup
.
As documented in the setDuplicateParentStateEnabled
method, if the child view has additional states (like checked state for a checkbox), these won't be affected by the parent.
The xml analogue is android:duplicateParentState="true"
.
If you want to understand AutoResetEvent and ManualResetEvent you need to understand not threading but interrupts!
.NET wants to conjure up low-level programming the most distant possible.
An interrupts is something used in low-level programming which equals to a signal that from low became high (or viceversa). When this happens the program interrupt its normal execution and move the execution pointer to the function that handles this event.
The first thing to do when an interrupt happend is to reset its state, becosa the hardware works in this way:
This is the difference between ManualResetEvent and AutoResetEvent.
If a ManualResetEvent happen and I do not reset it, the next time it happens I will not be able to listen it.
After allocating DateFormatter
you need to give the formatted string
then you can convert as string like this way
var date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let myString = formatter.string(from: date)
let yourDate: Date? = formatter.date(from: myString)
formatter.dateFormat = "dd-MMM-yyyy"
let updatedString = formatter.string(from: yourDate!)
print(updatedString)
OutPut

My implement from scratch:
FILE *pFile = fopen(your_file_path, "r");
int nbytes = 1024;
char *line = (char *) malloc(nbytes);
char *buf = (char *) malloc(nbytes);
size_t bytes_read;
int linesize = 0;
while (fgets(buf, nbytes, pFile) != NULL) {
bytes_read = strlen(buf);
// if line length larger than size of line buffer
if (linesize + bytes_read > nbytes) {
char *tmp = line;
nbytes += nbytes / 2;
line = (char *) malloc(nbytes);
memcpy(line, tmp, linesize);
free(tmp);
}
memcpy(line + linesize, buf, bytes_read);
linesize += bytes_read;
if (feof(pFile) || buf[bytes_read-1] == '\n') {
handle_line(line);
linesize = 0;
memset(line, '\0', nbytes);
}
}
free(buf);
free(line);
Try this one
$('<div></div>').appendTo('body')
.html('<div><h6>Yes or No?</h6></div>')
.dialog({
modal: true, title: 'message', zIndex: 10000, autoOpen: true,
width: 'auto', resizable: false,
buttons: {
Yes: function () {
doFunctionForYes();
$(this).dialog("close");
},
No: function () {
doFunctionForNo();
$(this).dialog("close");
}
},
close: function (event, ui) {
$(this).remove();
}
});
I use format, Number, 2 decimal places & tick ' use 1000 separater ', then go to 'File', 'Options', 'Advanced', scroll down to 'When calculating this workbook' and tick 'set precision as displayed'. You get an error message about losing accuracy, that's good as it means it is rounding to 2 decimal places. So much better than bothering with adding a needless ROUND function.
Not exactly your problem but a similar one.
If you have more than one formatting in your string entry, you should not use "%s" multiple times.
DON'T :
<string name="entry">Planned time %s - %s (%s)</string>
DO :
<string name="entry">Planned time %1$s - %2$s (%3$s)</string>
if your field name is Roles and table name is table1 you can use following to search
DECLARE @Role varchar(50);
SELECT * FROM table1
WHERE Roles.exist ('/root/role = sql:variable("@Role")') = 1
@Combii I found a way to swap
CMD+1, CMD+2, CMD+3 with CTRL+1, CTRL+2, CTRL+3, ...
In macOS, go to:
Code > Preferences > Keyboard Shortcuts
On that page, click the button on the top right of the page...
and append the configuration below, then save.
[
{
"key": "cmd+0",
"command": "workbench.action.openLastEditorInGroup"
},
{
"key": "cmd+1",
"command": "workbench.action.openEditorAtIndex1"
},
{
"key": "cmd+2",
"command": "workbench.action.openEditorAtIndex2"
},
{
"key": "cmd+3",
"command": "workbench.action.openEditorAtIndex3"

You now can use CMD+[1-9] to switch between tabs and CTRL+[1-3] to focus editor groups! Hope this answer is helpful.
I know you asked to Rebase, but I'd Cherry-Pick the commits I wanted to move from Branch2 to Branch1 instead. That way, I wouldn't need to care about when which branch was created from master, and I'd have more control over the merging.
a -- b -- c <-- Master
\ \
\ d -- e -- f -- g <-- Branch1 (Cherry-Pick f & g)
\
f -- g <-- Branch2
I liked cocogza's answer except that calling base.IsValid resulted in a stack overflow exception as it would re-enter the IsValid method again and again. So I modified it to be for a specific type of validation, in my case it was for an e-mail address.
[AttributeUsage(AttributeTargets.Property)]
class ValidEmailAddressIfTrueAttribute : ValidationAttribute
{
private readonly string _nameOfBoolProp;
public ValidEmailAddressIfTrueAttribute(string nameOfBoolProp)
{
_nameOfBoolProp = nameOfBoolProp;
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (validationContext == null)
{
return null;
}
var property = validationContext.ObjectType.GetProperty(_nameOfBoolProp);
if (property == null)
{
return new ValidationResult($"{_nameOfBoolProp} not found");
}
var boolVal = property.GetValue(validationContext.ObjectInstance, null);
if (boolVal == null || boolVal.GetType() != typeof(bool))
{
return new ValidationResult($"{_nameOfBoolProp} not boolean");
}
if ((bool)boolVal)
{
var attribute = new EmailAddressAttribute {ErrorMessage = $"{value} is not a valid e-mail address."};
return attribute.GetValidationResult(value, validationContext);
}
return null;
}
}
This works much better! It doesn't crash and produces a nice error message. Hope this helps someone!
Copy your SDK folder and paste it in another folder without spaces (for example: "D: / Android / Sdk"), then open the SDK Manager, and change the Android SDK Location to the location of your new SDK folder
To add a little to @Bakuriu's answer:
If you already know where the warning is likely to occur then it's often cleaner to use the numpy.errstate
context manager, rather than numpy.seterr
which treats all subsequent warnings of the same type the same regardless of where they occur within your code:
import numpy as np
a = np.r_[1.]
with np.errstate(divide='raise'):
try:
a / 0 # this gets caught and handled as an exception
except FloatingPointError:
print('oh no!')
a / 0 # this prints a RuntimeWarning as usual
In my original example I had a = np.r_[0]
, but apparently there was a change in numpy's behaviour such that division-by-zero is handled differently in cases where the numerator is all-zeros. For example, in numpy 1.16.4:
all_zeros = np.array([0., 0.])
not_all_zeros = np.array([1., 0.])
with np.errstate(divide='raise'):
not_all_zeros / 0. # Raises FloatingPointError
with np.errstate(divide='raise'):
all_zeros / 0. # No exception raised
with np.errstate(invalid='raise'):
all_zeros / 0. # Raises FloatingPointError
The corresponding warning messages are also different: 1. / 0.
is logged as RuntimeWarning: divide by zero encountered in true_divide
, whereas 0. / 0.
is logged as RuntimeWarning: invalid value encountered in true_divide
. I'm not sure why exactly this change was made, but I suspect it has to do with the fact that the result of 0. / 0.
is not representable as a number (numpy returns a NaN in this case) whereas 1. / 0.
and -1. / 0.
return +Inf and -Inf respectively, per the IEE 754 standard.
If you want to catch both types of error you can always pass np.errstate(divide='raise', invalid='raise')
, or all='raise'
if you want to raise an exception on any kind of floating point error.
There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.
When you define your list as:
List myList = new ArrayList();
you can only call methods and reference members that are defined in the List interface. If you define it as:
ArrayList myList = new ArrayList();
you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.
Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).
That's called polymorphism. You can read up on it.
To maven, the build process is arranged as a set of artifacts. Artifacts include:
Artifacts live in repositories.
A couple other examples of declarative programming:
Declarative programming is nice because it can help simplify your mental model* of code, and because it might eventually be more scalable.
For example, let's say you have a function that does something to each element in an array or list. Traditional code would look like this:
foreach (object item in MyList)
{
DoSomething(item);
}
No big deal there. But what if you use the more-declarative syntax and instead define DoSomething() as an Action? Then you can say it this way:
MyList.ForEach(DoSometing);
This is, of course, more concise. But I'm sure you have more concerns than just saving two lines of code here and there. Performance, for example. The old way, processing had to be done in sequence. What if the .ForEach() method had a way for you to signal that it could handle the processing in parallel, automatically? Now all of a sudden you've made your code multi-threaded in a very safe way and only changed one line of code. And, in fact, there's a an extension for .Net that lets you do just that.
In my case AutoMapper works well.
AutoMapper can map to/from dynamic objects without any explicit configuration:
public class Foo {
public int Bar { get; set; }
public int Baz { get; set; }
}
dynamic foo = new MyDynamicObject();
foo.Bar = 5;
foo.Baz = 6;
Mapper.Initialize(cfg => {});
var result = Mapper.Map<Foo>(foo);
result.Bar.ShouldEqual(5);
result.Baz.ShouldEqual(6);
dynamic foo2 = Mapper.Map<MyDynamicObject>(result);
foo2.Bar.ShouldEqual(5);
foo2.Baz.ShouldEqual(6);
Similarly you can map straight from dictionaries to objects, AutoMapper will line up the keys with property names.

for WPF: (where lblInfo is a label, chkRun is a checkBox)
this.Topmost is just to keep my app on the top of other windows, you will also need to add a using statement " using Microsoft.Win32; ", StartupWithWindows is my application's name

this.Topmost = false;
}
// Check to see the current state (running at startup or not)
if (rkApp.GetValue("StartupWithWindows") == null)
{
// The value doesn't exist, the application is not set to run at startup, Check box
chkRun.IsChecked = false;
lblInfo.Content = "The application doesn't run at startup";

$("#grid_GridHeader:first")
works as well.
IMO the parameters should be better as query arguments. The url is used to identify the resource, while the added query parameters to specify which part of the resource you want, any state the resource should have, etc.
You can overwrite the classes in your own css using !important, e.g. if you want to get rid of the rounded corners.
.ui-corner-all
{
border-radius: 0px !important;
}
I always go with the generic css title with my setup. I'm just building analytics for my blog admin page. I don't need anything fancy. Here's some code...
let comps = g.selectAll('.myClass')
.data(data)
.enter()
.append('rect')
...styling...
...transitions...
...whatever...
g.selectAll('.myClass')
.append('svg:title')
.text((d, i) => d.name + '-' + i);
And a screenshot of chrome...

This one did it for me:
var input = $("<input>")
.attr("type", "hidden")
.attr("name", "mydata").val("bla");
$('#form1').append(input);
is based on the Daff's answer, but added the NAME attribute to let it show in the form collection and changed VALUE to VAL Also checked the ID of the FORM (form1 in my case)
used the Firefox firebug to check whether the element was inserted.
Hidden elements do get posted back in the form collection, only read-only fields are discarded.

First Record should be add
"_id" = 1 in your db
$database = "demo";
$collections ="democollaction";
echo getnextid($database,$collections);
function getnextid($database,$collections){
$m = new MongoClient();
$db = $m->selectDB($database);
$cursor = $collection->find()->sort(array("_id" => -1))->limit(1);
$array = iterator_to_array($cursor);
foreach($array as $value){
return $value["_id"] + 1;
}
}
Note that a select list is posted as null, hence your error complains that the viewdata property cannot be found.
Always reinitialize your select list within a POST action.
For further explanation: Persist SelectList in model on Post
You should read the XML file using specific XML modules. That way you can edit the XML document in memory and rewrite your changed XML document into the file.
Here is a quick start: http://docs.python.org/library/xml.dom.minidom.html
There are a lot of other XML utilities, which one is best depends on the nature of your XML file and in which way you want to edit it.

My solution was to use global session helper: session()
Its functionality is a little bit harder than $request->session().
writing:
session(['key'=>'value']);
pushing:
session()->push('key', $notification);
retrieving:
session('key');
You can easily import your model and run this:
from models import User
# User is the name of table that has a column name
users = User.query.all()
for user in users:
print user.name
Depending on your regex variant, you might be able to do simply this:
([\w-]+)
Also, you probably don't need the parentheses unless this is part of a larger expression.
You can just use the global object.
var X = ['a', 'b', 'c'];
global.x = X;
console.log(x);
//['a', 'b', 'c']
In the first case, there are two objects created.
In the second case, it's just one.
Although both ways str
is referring to "abc"
.
git pull
is really just a shorthand for git pull <remote> <branchname>
, in most cases it's equivalent to git pull origin master
. You will need to add another remote and pull explicitly from it. This page describes it in detail:
You can specify config file location with VM argument -Dlog4j.configuration="file:/C:/workspace3/local/log4j.properties"
Use this pattern "^\d*(\.\d{2}$)?"
There are several tools for converting Matlab to Python code.
The only one that's seen recent activity (last commit from June 2018) is Small Matlab to Python compiler (also developed here: SMOP@chiselapp).
Other options include:
Also, for those interested in an interface between the two languages and not conversion:
pymatlab
: communicate from Python by sending data to the MATLAB workspace, operating on them with scripts and pulling back the resulting data.pymat2
: continuation of the seemingly abandoned PyMat.mlabwrap
, mlabwrap-purepy: make Matlab look like Python library (based on PyMat).oct2py
: run GNU Octave commands from within Python.pymex
: Embeds the Python Interpreter in Matlab, also on File Exchange.matpy
: Access MATLAB in various ways: create variables, access .mat files, direct interface to MATLAB engine (requires MATLAB be installed).Btw might be helpful to look here for other migration tips:
On a different note, though I'm not a fortran
fan at all, for people who might find it useful there is:
You can effectively remove scientific notation in printing with this code:

All solutions based on array_keys don't work for mixed arrays. Solution is simple:
echo array_search($needle,array_keys($haystack), true);
From php.net: If the third parameter strict is set to TRUE then the array_search() function will search for identical elements in the haystack. This means it will also perform a strict type comparison of the needle in the haystack, and objects must be the same instance.
I tried following this, and got the error
TypeError: ufunc 'true_divide' output (typecode 'd') could not be coerced to provided output parameter (typecode 'l') according to the casting rule ''same_kind''
The numpy
array I was trying to normalize was an integer
array. It seems they deprecated type casting in versions > 1.10
, and you have to use numpy.true_divide()
to resolve that.
arr = np.array(img)
arr = np.true_divide(arr,[255.0],out=None)
img
was an PIL.Image
object.
I'm just starting some string manipulations and found this question. I was probably trying to do something like the OP, "usual me". The previous answers did not clear up my confusion, but after thinking a little about it I finally "got it".
As long as a
, b
, c
, d
, and e
have the same value, they reference to the same place. Memory is saved. As soon as the variable start to have different values, they get start to have different references. My learning experience came from this code:
import copy
a = 'hello'
b = str(a)
c = a[:]
d = a + ''
e = copy.copy(a)
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e
e = a + 'something'
a = 'goodbye'
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e
The printed output is:
[4538504992, 4538504992, 4538504992, 4538504992, 4538504992]
hello hello hello hello hello
[6113502048, 4538504992, 4538504992, 4538504992, 5570935808]

The static
keyword modifies the lifecycle of a method or variable within a class. A static
method or variable is created at the time a class is loaded. A method or variable that is not declared as static
is created only when the class is instantiated as an object for example by using the new
operator.
The lifecycle of a class, in broad terms, is:
new
operator using the class to make an instance of the class as an actual object and then when done with the object In order to have an initial entry point for an application, Java has adopted the convention that the Java program must have a class that contains a method with an agreed upon or special name. This special method is called main()
. Since the method must exist whether the class containing the main method has been instantiated or not, the main()
method must be declared with the static
modifier so that as soon as the class is loaded, the main()
method is available.
The result is that when you start your Java application by a command line such as java helloworld
a series of actions happen. First of all a Java Virtual Machine is started up and initialized. Next the helloworld.class file containing the compiled Java code is loaded into the Java Virtual Machine. Then the Java Virtual Machine looks for a method in the helloworld
class that is called main(String [] args)
. this method must be static
so that it will exist even though the class has not actually been instantiated as an object. The Java Virtual Machine does not create an instance of the class by creating an object from the class. It just loads the class and starts execution at the main()
method.
So you need to create an instance of your class as an object and then you can access the methods and variables of the class that have not been declared with the static
modifier. Once your Java program has started with the main()
function you can then use any variables or methods that have the modifier of static
since they exist as part of the class being loaded.
However, those variables and methods of the class which are outside of the main()
method which do not have the static
modifier can not be used until an instance of the class has been created as an object within the main()
method. After creating the object you can then use the variables and methods of the object. An attempt to use the variables and methods of the class which do not have the static
modifier without going through an object of the class is caught by the Java compiler at compile time and flagged as an error.
import java.io.*;
class HelloWorld {
int myInt; // this is a class variable that is unique to each object
static int myInt2; // this is a class variable shared by all objects of this class
static void main (String [] args) {
// this is the main entry point for this Java application
System.out.println ("Hello, World\n");
myInt2 = 14; // able to access the static int
HelloWorld myWorld = new HelloWorld();
myWorld.myInt = 32; // able to access non-static through an object
}
}
You can try this it will help for you.You can't get path from WhatsApp directly.If you need an file path first copy file and send new file path. Using the code below
public static String getFilePathFromURI(Context context, Uri contentUri) {
String fileName = getFileName(contentUri);
if (!TextUtils.isEmpty(fileName)) {
File copyFile = new File(TEMP_DIR_PATH + fileName+".jpg");
copy(context, contentUri, copyFile);
return copyFile.getAbsolutePath();
}
return null;
}
public static String getFileName(Uri uri) {
if (uri == null) return null;
String fileName = null;
String path = uri.getPath();
int cut = path.lastIndexOf('/');
if (cut != -1) {
fileName = path.substring(cut + 1);
}
return fileName;
}
public static void copy(Context context, Uri srcUri, File dstFile) {
try {
InputStream inputStream = context.getContentResolver().openInputStream(srcUri);
if (inputStream == null) return;
OutputStream outputStream = new FileOutputStream(dstFile);
IOUtils.copy(inputStream, outputStream);
inputStream.close();
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
Then IOUtils class is like below
public class IOUtils {
private static final int BUFFER_SIZE = 1024 * 2;
private IOUtils() {
// Utility class.
}
public static int copy(InputStream input, OutputStream output) throws Exception, IOException {
byte[] buffer = new byte[BUFFER_SIZE];
BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);
BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);
int count = 0, n = 0;
try {
while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {
out.write(buffer, 0, n);
count += n;
}
out.flush();
} finally {
try {
out.close();
} catch (IOException e) {
Log.e(e.getMessage(), e.toString());
}
try {
in.close();
} catch (IOException e) {
Log.e(e.getMessage(), e.toString());
}
}
return count;
}
}

Put in other words, this error is telling you that SQL Server does not know which B
to select from the group.
Either you want to select one specific value (e.g. the MIN
, SUM
, or AVG
) in which case you would use the appropriate aggregate function, or you want to select every value as a new row (i.e. including B
in the GROUP BY
field list).
Consider the following data:
ID A B 1 1 13 1 1 79 1 2 13 1 2 13 1 2 42
The query
SELECT A, COUNT(B) AS T1
FROM T2
GROUP BY A
would return:
A T1 1 2 2 3
which is all well and good.
However consider the following (illegal) query, which would produce this error:
SELECT A, COUNT(B) AS T1, B
FROM T2
GROUP BY A
And its returned data set illustrating the problem:
A T1 B 1 2 13? 79? Both 13 and 79 as separate rows? (13+79=92)? ...? 2 3 13? 42? ...?
However, the following two queries make this clear, and will not cause the error:
Using an aggregate
SELECT A, COUNT(B) AS T1, SUM(B) AS B
FROM T2
GROUP BY A
would return:
A T1 B 1 2 92 2 3 68
Adding the column to the GROUP BY
list
SELECT A, COUNT(B) AS T1, B
FROM T2
GROUP BY A, B
would return:
A T1 B 1 1 13 1 1 79 2 2 13 2 1 42

Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", "10.101.3.229");
And if you have a port associated, then set this as well.
properties.setProperty("mail.smtp.port", "8080");

I agree with @Richard Morgan ... what you are doing should be working, so more information may be needed.
Microsoft has some suggestions on options to protect your Excel 2003 worksheets.
Here is a little more info ...
From help files (Protect Method):
expression.Protect(Password, Structure, Windows)
expression Required. An expression that returns a Workbook object.
Password Optional Variant. A string that specifies a case-sensitive password for the worksheet or workbook. If this argument is omitted, you can unprotect the worksheet or workbook without using a password. Otherwise, you must specify the password to unprotect the worksheet or workbook. If you forget the password, you cannot unprotect the worksheet or workbook. It's a good idea to keep a list of your passwords and their corresponding document names in a safe place.
Structure Optional Variant. True to protect the structure of the workbook (the relative position of the sheets). The default value is False.
Windows Optional Variant. True to protect the workbook windows. If this argument is omitted, the windows aren’t protected.
ActiveWorkbook.Protect Password:="password", Structure:=True, Windows:=True
If you want to work at the worksheet level, I used something similar years ago when I needed to protect/unprotect:
Sub ProtectSheet()
ActiveSheet.Protect "password", True, True
End Sub
Sub UnProtectSheet()
ActiveSheet.Unprotect "password"
End Sub
Sub protectAll()
Dim myCount
Dim i
myCount = Application.Sheets.Count
Sheets(1).Select
For i = 1 To myCount
ActiveSheet.Protect "password", true, true
If i = myCount Then
End
End If
ActiveSheet.Next.Select
Next i
End Sub
I asked myself the very same questions. When I looked into it I found the choices overwhelming.

To use arrow functions with function.prototype.call
, I made a helper function on the object prototype:
// Using
// @func = function() {use this here} or This => {use This here}
using(func) {
return func.call(this, this);
}
usage
var obj = {f:3, a:2}
.using(This => This.f + This.a) // 5
Edit
You don't NEED a helper. You could do:
var obj = {f:3, a:2}
(This => This.f + This.a).call(undefined, obj); // 5
clearfix
is the same as overflow:hidden
. Both clear floated children of the parent, but clearfix
will not cut off the element which overflow to it's parent
.
It also works in IE8 & above.
There is no need to define "."
in content & .clearfix. Just write like this:
.clr:after {
clear: both;
content: "";
display: block;
}
HTML
<div class="parent clr"></div>

you can simply use varialbles and one file to check for running your program. when open the file contain a value and when program closes changes this value to another one.
It works fine. I am trying it here with functions as list objects:
from random import shuffle
def foo1():
print "foo1",
def foo2():
print "foo2",
def foo3():
print "foo3",
A=[foo1,foo2,foo3]
for x in A:
x()
print "\r"
shuffle(A)
for y in A:
y()
It prints out: foo1 foo2 foo3 foo2 foo3 foo1 (the foos in the last row have a random order)
Try this
function submitRequest(buttonId) {
if (document.getElementById(buttonId) == null
|| document.getElementById(buttonId) == undefined) {

if (document.getElementById(buttonId).dispatchEvent) {
var e = document.createEvent("MouseEvents");
e.initEvent("click", true, true);
document.getElementById(buttonId).dispatchEvent(e);
} else {
document.getElementById(buttonId).click();
}
}
and you can use it like
submitRequest("target-element-id");

kinda weird that apple only supports 2 objects to be send and didnt make it more generic.
Select * from table where name like search_criteria
if you are expecting the user to add their own wildcards...
Instead of adding "ws." before every Range, as suggested above, you can add "ws.activate" before Call instead.
This will get you into the worksheet you want to work on.
Try This
SELECT DISTINCT so.name
FROM syscomments sc
INNER JOIN sysobjects so ON sc.id=so.id
WHERE sc.TEXT LIKE '%your table name%'
It's more standard to use the format yyyy-mm-dd hh:mm:ss (IE: 2009-06-23 19:30:20)
Using that you won't have to worry about the format of the date (MM/DD/YYYY or DD/MM/YYYY). It will work with all of them.
If you want the second highest number you can use
=LARGE(E4:E9;2)
although that doesn't account for duplicates so you could get the same result as the Max
If you want the largest number that is smaller than the maximum number you can use this version
=LARGE(E4:E9;COUNTIF(E4:E9;MAX(E4:E9))+1)
You can use this to continue using the type Date and a more legible code, if you preffer:
import org.apache.commons.lang.time.DateUtils;
...
Date yourDate = DateUtils.addDays(new Date(), *days here*);
To schedule the update to be automatic you should:
If you cannot find the Schedule settings, look under: Properties, Edit, Triggers.
If you have both versions you can create a merge replication from new to old. Create a merge publication on your newer sql server and a subscription on the older version. After initializing the subscription you can create a backup of the database with the same structure and the same content but in an older version and restore it on your old target server. You can use this method also with sql server 2016 to target 2014, 2012 or 2008.

functional requirements are the main things that the user expects from the software for example if the application is a banking application that application should be able to create a new account, update the account, delete an account, etc. functional requirements are detailed and are specified in the system design
Non-functional requirement are not straight forward the requirement of the system rather it is related to usability( in some way ) for example for a banking application a major non-functional requirement will be available the application should be available 24/7 with no downtime if possible.

To address the --rebase
vs. --merge
option:
Let's say you have super repository A and submodule B and want to do some work in submodule B. You've done your homework and know that after calling
git submodule update
you are in a HEAD-less state, so any commits you do at this point are hard to get back to. So, you've started work on a new branch in submodule B
cd B
git checkout -b bestIdeaForBEver
<do work>
Meanwhile, someone else in project A has decided that the latest and greatest version of B is really what A deserves. You, out of habit, merge the most recent changes down and update your submodules.
<in A>
git merge develop
git submodule update
Oh noes! You're back in a headless state again, probably because B is now pointing to the SHA associated with B's new tip, or some other commit. If only you had:
git merge develop
git submodule update --rebase
Fast-forwarded bestIdeaForBEver to b798edfdsf1191f8b140ea325685c4da19a9d437.
Submodule path 'B': rebased into 'b798ecsdf71191f8b140ea325685c4da19a9d437'
Now that best idea ever for B has been rebased onto the new commit, and more importantly, you are still on your development branch for B, not in a headless state!
(The --merge
will merge changes from beforeUpdateSHA to afterUpdateSHA into your working branch, as opposed to rebasing your changes onto afterUpdateSHA.)

For completeness' sake, I thought it would be worthwhile summarizing the various possible outcomes and supplying references for the exact behaviour of each:
__file__
is the currently executing file, as detailed in the official documentation:
__file__
is the pathname of the file from which the module was loaded, if it was loaded from a file. The__file__
attribute may be missing for certain types of modules, such as C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.
From Python3.4 onwards, per issue 18416, __file__
is always an absolute path, unless the currently executing file is a script that has been executed directly (not via the interpreter with the -m
command line option) using a relative path.
__main__.__file__
(requires importing __main__
) simply accesses the aforementioned __file__
attribute of the main module, e.g. of the script that was invoked from the command line.
From Python3.9 onwards, per issue 20443, the __file__
attribute of the __main__
module became an absolute path, rather than a relative path.
sys.argv[0]
(requires importing sys
) is the script name that was invoked from the command line, and might be an absolute path, as detailed in the official documentation:
argv[0]
is the script name (it is operating system dependent whether this is a full pathname or not). If the command was executed using the-c
command line option to the interpreter,argv[0]
is set to the string'-c'
. If no script name was passed to the Python interpreter,argv[0]
is the empty string.
As mentioned in another answer to this question, Python scripts that were converted into stand-alone executable programs via tools such as py2exe or PyInstaller might not display the desired result when using this approach (i.e. sys.argv[0]
would hold the name of the executable rather than the name of the main Python file within that executable).
If none of the aforementioned options seem to work, probably due to an atypical execution process or an irregular import operation, the inspect module might prove useful. In particular, invoking inspect.stack()[-1][1]
should work, although it would raise an exception when running in an implementation without Python stack frame.
From Python3.6 onwards, and as detailed in another answer to this question, it's possible to install an external open source library, lib_programname, which is tailored to provide a complete solution to this problem.
This library iterates through all of the approaches listed above until a valid path is returned. If all of them fail, it raises an exception. It also tries to address various pitfalls, such as invocations via the pytest framework or the pydoc module.
import lib_programname
# this returns the fully resolved path to the launched python program
path_to_program = lib_programname.get_path_executed_script() # type: pathlib.Path
When dealing with an approach that happens to return a relative path, it might be tempting to invoke various path manipulation functions, such as os.path.abspath(...)
or os.path.realpath(...)
in order to extract the full or real path.
However, these methods rely on the current path in order to derive the full path. Thus, if a program first changes the current working directory, for example via os.chdir(...)
, and only then invokes these methods, they would return an incorrect path.
If the current script is a symbolic link, then all of the above would return the path of the symbolic link rather than the path of the real file and os.path.realpath(...)
should be invoked in order to extract the latter.
os.path.basename(...)
may be invoked on any of the above in order to extract the actual file name and os.path.splitext(...)
may be invoked on the actual file name in order to truncate its suffix, as in os.path.splitext(os.path.basename(...))
.
From Python 3.4 onwards, per PEP 428, the PurePath
class of the pathlib
module may be used as well on any of the above. Specifically, pathlib.PurePath(...).name
extracts the actual file name and pathlib.PurePath(...).stem
extracts the actual file name without its suffix.
you have to reason in terms of hased password:
store the password as md5('bob123');
when bob is register to your app
$query = "INSERT INTO users (username,password) VALUES('bob','".md5('bob123')."');
then, when bob is logging-in:
$query = "SELECT * FROM users WHERE username = 'bob' AND password = '".md5('bob123')."';
obvioulsy use variables for username and password, these queries are generated by php and then you can execute them on mysql
This worked for me
var dateToFormat = "2018-05-16 12:57:13"; //TIMESTAMP
moment(dateToFormat).format("DD/MM/YYYY"); // you get "16/05/2018"

Nowadays, if you use a HTML5 form with type=email
then you're already by 80% safe since browser engines have their own validator. To complement it, add this regex to your preg_match_all()
and negate it:
if (!preg_match_all("/(?![[:alnum:]]|@|-|_|\.)./",$email)) { .. }
Find the regex used by HTML5 forms for validation

These also include stuff you may have set in your profile startup script.
Note if you have so many tabs open that Google Chrome is only showing the favicons then Google Chrome won't show the favicon for the selected tab, so if you keep reloading the tab with your page loaded in order to see your new favicon you will only see the text of your page's title.
You will need to reload your page, and then select a different tab in order to see your favicon.
The options for popen
can be used in call
args,
bufsize=0,
executable=None,
stdin=None,
stdout=None,
stderr=None,
preexec_fn=None,
close_fds=False,
shell=False,
cwd=None,
env=None,
universal_newlines=False,
startupinfo=None,
creationflags=0
So...
subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], stdout=myoutput)
Then you can do what you want with myoutput
(which would need to be a file btw).
Also, you can do something closer to a piped output like this.
dmesg | grep hda
would be:
p1 = Popen(["dmesg"], stdout=PIPE)
p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]
There's plenty of lovely, useful info on the python manual page.
Others ways to do the same is:
el = L[0][0]
m=len(L)
print L == [[el]*m]*m
Or:
first_el = L[0][0]
print all(el == first_el for inner_list in L for el in inner_list)
Please use below function if you don't want to round off.
function ConvertToDecimal(num) {
num = num.toString(); //If it's not already a String
num = num.slice(0, (num.indexOf(".")) + 3); //With 3 exposing the hundredths place
alert('M : ' + Number(num)); //If you need it back as a Number
}
This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''
Assuming the first parameter is an empty variable here is a simple example:
Wrong
nvl( ,0)
Fix
nvl('' ,0)
Put your query into your database software and check it for that error. Generally this is an easy fix
For those of you using pytest with mocker here is how I mocked datetime.datetime.now()
which is very similar to the original question.
test_get_now(mocker):
datetime_mock = mocker.patch("blackline_accounts_import.datetime",)
datetime_mock.datetime.now.return_value=datetime.datetime(2019,3,11,6,2,0,0)
now == function_being_tested() # run function
assert now == datetime.datetime(2019,3,11,6,2,0,0)
Essentially the mock has to be set to return the specified date. You aren't able to patch over datetime's object directly.
Another variation. This one
NotSupportedException
if the type can not be converted from string
. For instance, a custom struct without a type converter.(T?)null
if the string fails to parse. No need to check for null or whitespace. using System.ComponentModel;
public static Nullable<T> ToNullable<T>(this string s) where T : struct
{
var ret = new Nullable<T>();
var conv = TypeDescriptor.GetConverter(typeof(T));
if (!conv.CanConvertFrom(typeof(string)))
{
throw new NotSupportedException();
}
if (conv.IsValid(s))
{
ret = (T)conv.ConvertFrom(s);
}
return ret;
}

You can use send

i = 0
while i < length:
val = (yield i)
if val == 'length':
yield length
i += 1
it = counter()
print(it.next())
#0
print(it.next())
#1
print(it.send('length'))
#10
print(it.next())
#2
print(it.next())

Could you not have simply added:
align-items:center;
to a new class in your row div. Essentially:
<div class="row align_center">
.align_center { align-items:center; }
The error message says that getComputedStyle
requires the parameter to be Element
type. You receive it because the parameter has an incorrect type.
The most common case is that you try to pass an element that doesn't exist as an argument:
my_element = document.querySelector(#non_existing_id);
Now that element is null
, this will result in mentioned error:
my_style = window.getComputedStyle(my_element);
If it's not possible to always get element correctly, you can, for example, use the following to end function if querySelector
didn't find any match:
if (my_element === null) return;

It sounds like you might just need to use a view. A view allows a query to be represented as a table so it, the view, can be queried.
The Void class is an uninstantiable placeholder class to hold a reference to the Class object representing the Java keyword void.
So any of the following would suffice:
Object
and returning new Object()
or null
Void
and returning null
NullObject
of yoursYou can't make this method void
, and anything else returns something. Since that something is ignored, you can return anything.
The argument to remove()
is a filter document, so passing in an empty document means 'remove all':
db.user.remove({})
However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove()
call vs the drop()
call.
More details in the docs.
Of course slideDown
and slideUp
don't do what you want, you said you want it to be left/right, not top/down.
If your edit to your question adding the jquery-ui
tag means you're using jQuery UI, I'd go with nnnnnn's solution, using jQuery UI's slide
effect.
If not:
Assuming the menu starts out visible (edit: oops, I see that isn't a valid assumption; see note below), if you want it to slide out to the left and then later slide back in from the left, you could do this: Live Example | Live Source
$(document).ready(function() {
// Hide menu once we know its width
$('#showmenu').click(function() {
var $menu = $('.menu');
if ($menu.is(':visible')) {
// Slide away
$menu.animate({left: -($menu.outerWidth() + 10)}, function() {
$menu.hide();
});
}
else {
// Slide in
$menu.show().animate({left: 0});
}
});
});
You'll need to put position: relative
on the menu element.
Note that I replaced your toggle
with click
, because that form of toggle
was removed from jQuery.
If you want the menu to start out hidden, you can adjust the above. You want to know the element's width, basically, when putting it off-page.
This version doesn't care whether the menu is initially-visible or not: Live Copy | Live Source

if ($menu.is(':visible')) {

$menu.animate({left: -($menu.outerWidth() + 10)}, function() {
$menu.hide();
});
}

// Slide in
$menu.show().css("left", -($menu.outerWidth() + 10)).animate({left: 0});
}
});
});

Ruby has no pre/post increment/decrement operator. For instance,
x++
orx--
will fail to parse. More importantly,++x
or--x
will do nothing! In fact, they behave as multiple unary prefix operators:-x == ---x == -----x == ......
To increment a number, simply writex += 1
.
Taken from "Things That Newcomers to Ruby Should Know " (archive, mirror)
That explains it better than I ever could.
EDIT: and the reason from the language author himself (source):
- ++ and -- are NOT reserved operator in Ruby.
- C's increment/decrement operators are in fact hidden assignment. They affect variables, not objects. You cannot accomplish assignment via method. Ruby uses +=/-= operator instead.
- self cannot be a target of assignment. In addition, altering the value of integer 1 might cause severe confusion throughout the program.
Old question, but I'd like to add something: when calling doPostBack()
you can use the server handler method for the action.
For an example:
__doPostBack('<%= btn.UniqueID%>', 'my args');
Will fire, on server:
protected void btn_Click(object sender, EventArgs e)
I didn't find a better way to get the argument, so I'm still using Request["__EVENTARGUMENT"]
.
Most simplest way is to use a IF(). Yes Mysql allows you to do conditional logic. IF function takes 3 params CONDITION, TRUE OUTCOME, FALSE OUTCOME.
So Logic is
if report.type = 'p'
amount = amount
else
amount = -1*amount
SQL
SELECT
id, IF(report.type = 'P', abs(amount), -1*abs(amount)) as amount
FROM report
You may skip abs() if all no's are +ve only
Try this
function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/);
return pattern.test(emailAddress);
};
int rows, cols , i, j;
printf("Enter number of rows and cols for the matrix: \n");
scanf("%d %d",&rows, &cols);
int mat[rows][cols];
printf("enter the matrix:");
for(i = 0; i < rows ; i++)
for(j = 0; j < cols; j++)
scanf("%d", &mat[i][j]);
printf("\nThe Matrix is:\n");
for(i = 0; i < rows ; i++)
{
for(j = 0; j < cols; j++)
{
printf("%d",mat[i][j]);
printf("\t");
}
printf("\n");
}
}
Each Entry object represents key-value pair. Field next refers to other Entry object if a bucket has more than 1 Entry.
Sometimes it might happen that hashCodes for 2 different objects are the same. In this case 2 objects will be saved in one bucket and will be presented as LinkedList. The entry point is more recently added object. This object refers to other object with next field and so one. Last entry refers to null. When you create HashMap with default constructor
Array is gets created with size 16 and default 0.75 load balance.
UPDATE table SET column=0 WHERE column IS NULL
NSString* myNewString = [NSString stringWithFormat:@"%d", myInt];
You can use the PUT method and pass data that will be included in the body of the request:
let data = {"key":"value"}
$.ajax({
type: 'PUT',
url: 'http://example.com/api',
contentType: 'application/json',
data: JSON.stringify(data), // access in body
}).done(function () {
console.log('SUCCESS');
}).fail(function (msg) {
console.log('FAIL');
}).always(function (msg) {
console.log('ALWAYS');
});
Here's how I handle that:
$this->response_body = @file_get_contents($this->url, false, $context);
if ($this->response_body === false) {
$error = error_get_last();
$error = explode(': ', $error['message']);
$error = trim($error[2]) . PHP_EOL;
fprintf(STDERR, 'Error: '. $error);
die();
}
Because the answer is no longer valid with a more stable version of angular, I am posting a newer solution.
PHP Page: session.php
if (!isset($_SESSION))
{
session_start();
}
$_SESSION['variable'] = "hello world";
$sessions = array();
$sessions['variable'] = $_SESSION['variable'];
header('Content-Type: application/json');
echo json_encode($sessions);
Send back only the session variables you want in Angular not all of them don't want to expose more than what is needed.
JS All Together
var app = angular.module('StarterApp', []);
app.controller("AppCtrl", ['$rootScope', 'Session', function($rootScope, Session) {
Session.then(function(response){
$rootScope.session = response;
});
}]);
app.factory('Session', function($http) {
return $http.get('/session.php').then(function(result) {
return result.data;
});
});
HTML
Inside your html you can reference your session
<html ng-app="StarterApp">
<body ng-controller="AppCtrl">
{{ session.variable }}
</body>
Is there something special with that directory or are you really just asking how to copy directories?
Copy recursively via CLI:
cp -R <sourcedir> <destdir>
If you're only seeing the files under the sourcedir
being copied (instead of sourcedir
as well), that's happening because you kept the trailing slash for sourcedir
:
cp -R <sourcedir>/ <destdir>
The above only copies the files and their directories inside of sourcedir
. Typically, you want to include the directory you're copying, so drop the trailing slash:
cp -R <sourcedir> <destdir>
As of jQuery 1.4.1, the hover event works with live()
. It basically just binds to the mouseenter and mouseleave events, which you can do with versions prior to 1.4.1 just as well:
$("table tr")
.mouseenter(function() {
// Hover starts
})
.mouseleave(function() {
// Hover ends
});
This requires two binds but works just as well.
I had this same issue when trying to handle popping alerts and fading them. I searched around various places and found this to be my solution. Adding and removing the 'in' class fixed my issue.
window.setTimeout(function() { // hide alert message
$("#alert_message").removeClass('in');
}, 5000);
When using .remove() and similarly the .alert('close') solution I seemed to hit an issue with the alert being removed from the document, so if I wanted to use the same alert div again I was unable to. This solution means the alert is reusable without refreshing the page. (I was using aJax to submit a form and present feedback to the user)
$('#Some_Button_Or_Event_Here').click(function () { // Show alert message
$('#alert_message').addClass('in');
});
When Atom installs it automatically creates a symlink in your /usr/local/bin. However in case it hasn't, you can create it yourself on your Mac
ln -s /Applications/Atom.app/Contents/Resources/app/atom.sh /usr/local/bin/atom
Now you can use atom folder_name
to open a folder and atom file_name
to open a file.
Please look at this document
http://www.socialsecurity.gov/employer/randomization.html
The SSA is instituting a new policy the where all previously unused sequences are will be available for use.
Goes into affect June 25, 2011.
Taken from the new FAQ:
What changes will result from randomization?
The SSA will eliminate the geographical significance of the first three digits of the SSN, currently referred to as the area number, by no longer allocating the area numbers for assignment to individuals in specific states. The significance of the highest group number (the fourth and fifth digits of the SSN) for validation purposes will be eliminated. Randomization will also introduce previously unassigned area numbers for assignment excluding area numbers 000, 666 and 900-999. Top
Will SSN randomization assign group number (the fourth and fifth digits of the SSN) 00 or serial number (the last four digits of the SSN) 0000?
SSN randomization will not assign group number 00 or serial number 0000. SSNs containing group number 00 or serial number 0000 will continue to be invalid.
There are following three built-in build lifecycles:
Lifecycle default -> [validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy]
Lifecycle clean -> [pre-clean, clean, post-clean]
Lifecycle site -> [pre-site, site, post-site, site-deploy]
The flow is sequential, for example, for default lifecycle, it starts with validate, then initialize and so on...
You can check the lifecycle by enabling debug mode of mvn
i.e., mvn -X <your_goal>
Basically if you have a destructor (not the default destructor) it means that the class that you defined has some memory allocation. Suppose that the class is used outside by some client code or by you.
MyClass x(a, b);
MyClass y(c, d);
x = y; // This is a shallow copy if assignment operator is not provided
If MyClass has only some primitive typed members a default assignment operator would work but if it has some pointer members and objects that do not have assignment operators the result would be unpredictable. Therefore we can say that if there is something to delete in destructor of a class, we might need a deep copy operator which means we should provide a copy constructor and assignment operator.
Add android:hardwareAccelerated="true" in your manifests file like below it works for me
<activity
android:name=".activity.MyCardViewActivity"
android:hardwareAccelerated="true"></activity>
int cores = Runtime.getRuntime().availableProcessors();
If cores
is less than one, either your processor is about to die, or your JVM has a serious bug in it, or the universe is about to blow up.
This is all generally covered by Section 23.3.2 of SystemVerilog IEEE Std 1800-2012.
The simplest way is to instantiate in the main section of top, creating a named instance and wiring the ports up in order:
module top(
input clk,
input rst_n,
input enable,
input [9:0] data_rx_1,
input [9:0] data_rx_2,
output [9:0] data_tx_2
);
subcomponent subcomponent_instance_name (
clk, rst_n, data_rx_1, data_tx );
endmodule
This is described in Section 23.3.2.1 of SystemVerilog IEEE Std 1800-2012.
This has a few draw backs especially regarding the port order of the subcomponent code. simple refactoring here can break connectivity or change behaviour. for example if some one else fixs a bug and reorders the ports for some reason, switching the clk and reset order. There will be no connectivity issue from your compiler but will not work as intended.
module subcomponent(
input rst_n,
input clk,
...
It is therefore recommended to connect using named ports, this also helps tracing connectivity of wires in the code.
module top(
input clk,
input rst_n,
input enable,
input [9:0] data_rx_1,
input [9:0] data_rx_2,
output [9:0] data_tx_2
);
subcomponent subcomponent_instance_name (
.clk(clk), .rst_n(rst_n), .data_rx(data_rx_1), .data_tx(data_tx) );
endmodule
This is described in Section 23.3.2.2 of SystemVerilog IEEE Std 1800-2012.
Giving each port its own line and indenting correctly adds to the readability and code quality.
subcomponent subcomponent_instance_name (
.clk ( clk ), // input
.rst_n ( rst_n ), // input
.data_rx ( data_rx_1 ), // input [9:0]
.data_tx ( data_tx ) // output [9:0]
);
So far all the connections that have been made have reused inputs and output to the sub module and no connectivity wires have been created. What happens if we are to take outputs from one component to another:
clk_gen(
.clk ( clk_sub ), // output
.en ( enable ) // input
subcomponent subcomponent_instance_name (
.clk ( clk_sub ), // input
.rst_n ( rst_n ), // input
.data_rx ( data_rx_1 ), // input [9:0]
.data_tx ( data_tx ) // output [9:0]
);
This nominally works as a wire for clk_sub is automatically created, there is a danger to relying on this. it will only ever create a 1 bit wire by default. An example where this is a problem would be for the data:
Note that the instance name for the second component has been changed
subcomponent subcomponent_instance_name (
.clk ( clk_sub ), // input
.rst_n ( rst_n ), // input
.data_rx ( data_rx_1 ), // input [9:0]
.data_tx ( data_temp ) // output [9:0]
);
subcomponent subcomponent_instance_name2 (
.clk ( clk_sub ), // input
.rst_n ( rst_n ), // input
.data_rx ( data_temp ), // input [9:0]
.data_tx ( data_tx ) // output [9:0]
);
The issue with the above code is that data_temp is only 1 bit wide, there would be a compile warning about port width mismatch. The connectivity wire needs to be created and a width specified. I would recommend that all connectivity wires be explicitly written out.
wire [9:0] data_temp
subcomponent subcomponent_instance_name (
.clk ( clk_sub ), // input
.rst_n ( rst_n ), // input
.data_rx ( data_rx_1 ), // input [9:0]
.data_tx ( data_temp ) // output [9:0]
);
subcomponent subcomponent_instance_name2 (
.clk ( clk_sub ), // input
.rst_n ( rst_n ), // input
.data_rx ( data_temp ), // input [9:0]
.data_tx ( data_tx ) // output [9:0]
);
Moving to SystemVerilog there are a few tricks available that save typing a handful of characters. I believe that they hinder the code readability and can make it harder to find bugs.
Use .port
with no brackets to connect to a wire/reg of the same name. This can look neat especially with lots of clk and resets but at some levels you may generate different clocks or resets or you actually do not want to connect to the signal of the same name but a modified one and this can lead to wiring bugs that are not obvious to the eye.
module top(
input clk,
input rst_n,
input enable,
input [9:0] data_rx_1,
input [9:0] data_rx_2,
output [9:0] data_tx_2
);
subcomponent subcomponent_instance_name (
.clk, // input **Auto connect**
.rst_n, // input **Auto connect**
.data_rx ( data_rx_1 ), // input [9:0]
.data_tx ( data_tx ) // output [9:0]
);
endmodule
This is described in Section 23.3.2.3 of SystemVerilog IEEE Std 1800-2012.
Another trick that I think is even worse than the one above is .*
which connects unmentioned ports to signals of the same wire. I consider this to be quite dangerous in production code. It is not obvious when new ports have been added and are missing or that they might accidentally get connected if the new port name had a counter part in the instancing level, they get auto connected and no warning would be generated.
subcomponent subcomponent_instance_name (
.*, // **Auto connect**
.data_rx ( data_rx_1 ), // input [9:0]
.data_tx ( data_tx ) // output [9:0]
);
This is described in Section 23.3.2.4 of SystemVerilog IEEE Std 1800-2012.
You simply can't use View as a Header of ListView.
Because the view which is being passed in has to be inflated.
Look at my answer at Android ListView addHeaderView() nullPointerException for predefined Views for more info.
EDIT:
Look at this tutorial Android ListView and ListActivity - Tutorial .
EDIT 2: This link is broken Android ListActivity with a header or footer
Depending if you only need a couple attributes to be styled inline you can do something like this solution (and saves you from having to install a special package or create an extra element):
https://stackoverflow.com/a/42000085
<span class="something" datacustomattribute="">
Hello
</span>
.something::before {
content: attr(datascustomattribute);
position: absolute;
}
Note that the datacustomattribute
must start with data
and be all lowercase to satisfy React.
You can use this:
Range("MyTable[#Data]").Rows.Count
You have to distinguish between a table which has either one row of data or no data, as the previous code will return "1" for both cases. Use this to test for an empty table:
If WorksheetFunction.CountA(Range("MyTable[#Data]"))
I had a problem, and the method Mike advised worked partly, I had an error Dublicate Column name = '0', and changed the syntax of your query as this`
$tQ = "INSERT INTO names (name_id, surname_id, sum, sum2, sum3,sum4,sum5)
SELECT '$name', '$surname', '$sum', '$sum2', '$sum3','$sum4','$sum5'
FROM DUAL
WHERE NOT EXISTS (
SELECT sum FROM names WHERE name_id = '$name'
AND surname_id = '$surname') LIMIT 1;";
The problem was with column names. sum3 was equal to sum4 and mysql throwed dublicate column names, and I wrote the code in this syntax and it worked perfectly,
The best solution is to create singleton controller for your LED which will queue all commands and execute them with specified delay:
function LedController(timeout) {
this.timeout = timeout || 100;
this.queue = [];
this.ready = true;
}
LedController.prototype.send = function(cmd, callback) {
sendCmdToLed(cmd);
if (callback) callback();
// or simply `sendCmdToLed(cmd, callback)` if sendCmdToLed is async
};
LedController.prototype.exec = function() {
this.queue.push(arguments);
this.process();
};
LedController.prototype.process = function() {
if (this.queue.length === 0) return;
if (!this.ready) return;
var self = this;
this.ready = false;
this.send.apply(this, this.queue.shift());
setTimeout(function () {
self.ready = true;
self.process();
}, this.timeout);
};
var Led = new LedController();
Now you can call Led.exec
and it'll handle all delays for you:
Led.exec(cmd, function() {
console.log('Command sent');
});
Just took a look over the mustache docs and they support "inverted sections" in which they state
they (inverted sections) will be rendered if the key doesn't exist, is false, or is an empty list
http://mustache.github.io/mustache.5.html#Inverted-Sections
{{#value}}
value is true
{{/value}}
{{^value}}
value is false
{{/value}}
Here :name
is the symbol which point to the method name
of tag object.
When we pass &:name
to map
, it will treat name
as a proc object.
For short, tags.map(&:name)
acts as:
tags.map do |tag|
tag.name
end
You can use .val() to select the value, like the following:
function select_option(i) {
$("#span_id select").val(i);
}

GCD
is a low-level C-based API that enables very simple use of a task-based concurrency model. NSOperation
and NSOperationQueue
are Objective-C classes that do a similar thing. NSOperation
was introduced first, but as of 10.5 and iOS 2, NSOperationQueue
and friends are internally implemented using GCD
.
In general, you should use the highest level of abstraction that suits your needs. This means that you should usually use NSOperationQueue
instead of GCD
, unless you need to do something that NSOperationQueue
doesn't support.
Note that NSOperationQueue
isn't a "dumbed-down" version of GCD; in fact, there are many things that you can do very simply with NSOperationQueue
that take a lot of work with pure GCD
. (Examples: bandwidth-constrained queues that only run N operations at a time; establishing dependencies between operations. Both very simple with NSOperation
, very difficult with GCD
.) Apple's done the hard work of leveraging GCD to create a very nice object-friendly API with NSOperation
. Take advantage of their work unless you have a reason not to.
Caveat:
On the other hand, if you really just need to send off a block, and don't need any of the additional functionality that NSOperationQueue
provides, there's nothing wrong with using GCD. Just be sure it's the right tool for the job.
Ok - my case was not strictly related to this question, but I ended up on this page when Googling for the same exception; I queried an SQL database with LINQ when I got this exception.
private Table<SubscriptionModel> m_subscriptionsSql;
var query = from SubscriptionModel subscription in m_subscriptionsSql ...
Turned out I forgot to initialize my Table instance variable, that I used in the LINQ query.
m_subscriptionsSql = GetTable<SubscriptionModel>();
module.exports = (function () {
'use strict';
var foo = function () {
return {
public_method: function () {}
};
};
var bar = function () {
return {
public_method: function () {}
};
};
return {
module_a: foo,
module_b: bar
};
}());

I also issued this problem, and the server admins solved it by following the same solution as indu_teja proposed in http://www.sqlservercentral.com/Forums/Topic546566-146-1.aspx
The solution proposed by indu_teja says :
If you get this "SSPI Context Error". The issues we face are:
- We will not be able to connect to SQL Server remotely.
- However we will be able to connect to server with local account.
CAUSE: The issue might be becasue of no proper sync happenign fro the SPNs in Active directory.
RESOLUTION:
- You need to reset SPN. Use the synytax "SET SPN". You can check the syntax in net once.
- Change your sql server service account from domain account to Local account, recycle sql, and then reset again with your domain account and recycle sql server.
JavaScript only has a Number type that stores floating point values.
There is no int.
Edit:
If you want to format the number as a string with two digits after the decimal point use:
(4).toFixed(2)
Swift 2.0 Compability
func listWithFilter () {
let fileManager = NSFileManager.defaultManager()
// We need just to get the documents folder url
let documentsUrl = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL
do {
// if you want to filter the directory contents you can do like this:
if let directoryUrls = try? NSFileManager.defaultManager().contentsOfDirectoryAtURL(documentsUrl, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsSubdirectoryDescendants) {
print(directoryUrls)

OR
func listFiles() -> [String] {
var theError = NSErrorPointer()
let dirs = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true) as? [String]
if dirs != nil {
let dir = dirs![0]

let fileList = try NSFileManager.defaultManager().contentsOfDirectoryAtPath(dir)

My synopsis of rfc2397 is:
Once you've got your base64 encoded image data put it inside the <Image></Image> tags prefixed with "data:{mimetype};base64,
" this is similar to the prefixing done in the parenthesis of url()
definition in CSS or in the quoted value of the src
attribute of the img
tag in [X]HTML. You can test the data url in firefox by putting the data:image/...
line into the URL field and pressing enter, it should show your image.
For actually encoding I think we need to go over all your options, not just PHP, because there's so many ways to base64 encode something.
base64
command line tool. It's part of the GNU coreutils (v6+) and pretty much default in any Cygwin, Linux, GnuWin32 install, but not the BSDs I tried. Issue: $ base64 imagefile.ico > imagefile.base64.txt
A note on mime-types:
I would prefer you use one of image/png
image/jpeg
or image/gif
as I can't find the popular image/x-icon
. Should that be image/vnd.microsoft.icon
?
Also the other formats are much shorter.
compare 265 bytes vs 1150 bytes:

There's a new plugin which provides full theming for Eclipse:
http://brainwy.github.io/liclipse/
It's integrated with Eclipse Color Theme so that when a new theme is selected in preferences > general > appearance > color theme, the proper background is also applied to other parts of the IDE (theming everything or just views which are previously registered according to a combo in that same page).
And besides theming it provides a bunch of other things :)
$http.get(url).success(successCallback).error(errorCallback);
Replace successCallback and errorCallback with your functions.
Edit: Laurent's answer is more correct considering he is using then
. Yet I'm leaving this here as an alternative for the folks who will visit this question.
The answer to your question is yes and no, depending on what you mean by "inline function". If you're using the term like it's used in C++ development then the answer is no, you can't do that - even a lambda expression is a function call. While it's true that you can define inline lambda expressions to replace function declarations in C#, the compiler still ends up creating an anonymous function.
Here's some really simple code I used to test this (VS2015):
static void Main(string[] args)
{
Func<int, int> incr = a => a + 1;
Console.WriteLine($"P1 = {incr(5)}");
}
What does the compiler generate? I used a nifty tool called ILSpy that shows the actual IL assembly generated. Have a look (I've omitted a lot of class setup stuff)
This is the Main function:
IL_001f: stloc.0
IL_0020: ldstr "P1 = {0}"
IL_0025: ldloc.0
IL_0026: ldc.i4.5
IL_0027: callvirt instance !1 class [mscorlib]System.Func`2<int32, int32>::Invoke(!0)
IL_002c: box [mscorlib]System.Int32
IL_0031: call string [mscorlib]System.String::Format(string, object)
IL_0036: call void [mscorlib]System.Console::WriteLine(string)
IL_003b: ret
See those lines IL_0026 and IL_0027? Those two instructions load the number 5 and call a function. Then IL_0031 and IL_0036 format and print the result.
And here's the function called:
.method assembly hidebysig
instance int32 '<Main>b__0_0' (
int32 a
) cil managed
{
// Method begins at RVA 0x20ac
// Code size 4 (0x4)
.maxstack 8
IL_0000: ldarg.1
IL_0001: ldc.i4.1
IL_0002: add
IL_0003: ret
} // end of method '<>c'::'<Main>b__0_0'
It's a really short function, but it is a function.
Is this worth any effort to optimize? Nah. Maybe if you're calling it thousands of times a second, but if performance is that important then you should consider calling native code written in C/C++ to do the work.
In my experience readability and maintainability are almost always more important than optimizing for a few microseconds gain in speed. Use functions to make your code readable and to control variable scoping and don't worry about performance.

Requirements files use an expanded pip format, which is only useful if you need to complement your setup.py
with stronger constraints, for example specifying the exact urls some of the dependencies must come from, or the output of pip freeze
to freeze the entire package set to known-working versions. If you don't need the extra constraints, use only a setup.py
. If you feel like you really need to ship a requirements.txt
anyway, you can make it a single line:
.
It will be valid and refer exactly to the contents of the setup.py
that is in the same directory.
For better explain Dave Morrissey's answer I have made these steps for wrap with Console Output class in a laravel facade.
1) Create a Facade in your prefer folder (in my case app\Facades):
class ConsoleOutput extends Facade {
protected static function getFacadeAccessor() {
return 'consoleOutput';
}
}
2) Register a new Service Provider in app\Providers as follow:
class ConsoleOutputServiceProvider extends ServiceProvider
{
public function register(){
App::bind('consoleOutput', function(){
return new \Symfony\Component\Console\Output\ConsoleOutput();
});
}
}
3) Add all this stuffs in config\app.php file, registering the provider and alias.
'providers' => [
//other providers
App\Providers\ConsoleOutputServiceProvider::class
],
'aliases' => [
//other aliases
'ConsoleOutput' => App\Facades\ConsoleOutput::class,
],
That's it, now in any place of your Laravel application, just call your method in this way:
ConsoleOutput::writeln('hello');
Hope this help you.
Seems like you can't iterate through JSONArray
with a for each
. You can loop through your JSONArray
like this:
for (int i=0; i < arr.length(); i++) {
arr.getJSONObject(i);
}
Since it wasn't stated clearly, I just add this:
I was looking for a way to create a table which holds the number of occurrences of all the data types.
Say we have a data.frame
with two numeric and one logical column
dta <- data.frame(a = c(1,2,3),
b = c(4,5,6),
c = c(TRUE, FALSE, TRUE))
You can summarize the number of columns of each data type with that
table(unlist(lapply(dta, class)))
# logical numeric
# 1 2
This comes extremely handy, if you have a lot of columns and want to get a quick overview.

A good and simple way of drawing anti-aliased lines on a non anti-aliased render target is to draw rectangles of 4 pixel width with an 1x4 texture, with alpha channel values of {0.,1.,1.,0.}, and use linear filtering with mip-mapping off. This will make the lines 2 pixels thick, but you can change the texture for different thicknesses. This is faster and easier than barymetric calculations.
If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw
always interrupt the execution flow of the current method. a try
/catch
block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.
Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/
It can also be as simple as this.
@media (orientation: landscape) {
}
You can achieve that by using a FlatButton
that contains a Column
(for showing a text below the icon) or a Row
(for text next to the icon), and then having an Icon
Widget and a Text
widget as children.
Here's an example:
class MyPage extends StatelessWidget {
@override
Widget build(BuildContext context) =>
Scaffold(
appBar: AppBar(
title: Text("Hello world"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
FlatButton(
onPressed: () => {},
color: Colors.orange,
padding: EdgeInsets.all(10.0),
child: Column( // Replace with a Row for horizontal icon + text
children: <Widget>[
Icon(Icons.add),
Text("Add")
],
),
),

This will produce the following:
It's same as vikasdumca's steps, but thought to share the link.
run the following command
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
then
sudo apt-get install oracle-java8-installer
this would install oracle java 8 on ubuntu properly.

Like the other answers, it's impossible. Here is the comment about breaker in underscore underscore issue #21
Simpler way to solve is as
s = '1dfss3sw235fsf7s'
count = 0
temp = list(s)
for item in temp:
if(item.isdigit()):
count = count + 1
else:
pass
print count
If you are using anaconda to go into python environment you should have build up different environment for different python version
The following scripts may help you build up a new environment(running in anaconda prompt)
conda create -n py27 python=2.7 #for version 2.7
activate py27
conda create -n py36 python=3.6 #for version 3.6
activate py36
you may leave the environment back to your global env by typing
deactivate py27
or
deactivate py36
and then you can either switch to different environment using your anaconda UI with @Francisco Camargo 's answer
or you can stick to anaconda prompt using @Dan 's answer
If you are triggering the change with JS, let's say on click, there is a nice workaround.
You see, the problem happens because the animation is ignored on display:none
element but browser applies all the changes at once and the element is never display:block
while not animated at the same time.
The trick is to ask the browser to render the frame after changing the visibility but before triggering the animation.
Here is a JQuery example:
$('.child').css({"display":"block"});
//now ask the browser what is the value of the display property
$('.child').css("display"); //this will trigger the browser to apply the change. this costs one frame render
//now a change to opacity will trigger the animation
$('.child').css("opacity":100);
Apparently, _JAVA_OPTIONS
works on Linux, too:
$ export _JAVA_OPTIONS="-Xmx1g"
$ java -jar jconsole.jar &
Picked up _JAVA_OPTIONS: -Xmx1g
By trial and error, I've determined the following is required to set font size:
cex
doesn't work in hist()
. Use cex.axis
for the numbers on the axes, cex.lab
for the labels.cex
doesn't work in axis()
either. Use cex.axis
for the numbers on the axes.hist()
, you can set them using mtext()
. You can set the font size using cex
, but using a value of 1 actually sets the font to 1.5 times the default!!! You need to use cex=2/3
to get the default font size. At the very least, this is the case under R 3.0.2 for Mac OS X, using PDF output.pointsize
in pdf()
.I suppose it would be far too logical to expect R to (a) actually do what its documentation says it should do, (b) behave in an expected fashion.
REPEAT
...
UNTIL cond
Is equivalent to
while True:
...
if cond:
break
The accepted answer works for most cases, but it doesn't work well when your div
can vary greatly in height — the animation speed is not dependent on the actual height of the content, and it can look choppy.
You can still perform the actual animation with CSS, but you need to use JavaScript to compute the height of the items, instead of trying to use auto
. No jQuery is required, although you may have to modify this a bit if you want compatibility (works in the latest version of Chrome :)).
window.toggleExpand = function(element) {_x000D_
if (!element.style.height || element.style.height == '0px') { _x000D_

For application/msword and application/vnd.ms-excel, when I deleted the size restriction:
($_FILES["file"]["size"] < 20000)
...it worked ok.
using (MemoryStream mem = new MemoryStream())
{
SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(mem, SpreadsheetDocumentType.Workbook);
// Add a WorkbookPart to the document.
WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
// Add a WorksheetPart to the WorkbookPart.
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData());
// Add Sheets to the Workbook.
Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
// Add a row to the cell table.
Row row;
row = new Row() { RowIndex = 1 };
sheetData.Append(row);
// In the new row, find the column location to insert a cell in A1.
Cell refCell = null;
foreach (Cell cell in row.Elements<Cell>())
{
if (string.Compare(cell.CellReference.Value, "A1", true) > 0)
{
refCell = cell;
break;
}
}
// Add the cell to the cell table at A1.
Cell newCell = new Cell() { CellReference = "A1" };
row.InsertBefore(newCell, refCell);
// Set the cell value to be a numeric value of 100.
newCell.CellValue = new CellValue("100");
newCell.DataType = new EnumValue<CellValues>(CellValues.Number);
// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet()
{
Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart),
SheetId = 1,
Name = "mySheet"
};
sheets.Append(sheet);
workbookpart.Workbook.Save();
spreadsheetDocument.Close();
return File(mem.ToArray(), System.Net.Mime.MediaTypeNames.Application.Octet, "text.xlsx");

You can perform a simple each
loop on the range from 1 to `x´:
(1..x).each do |i|
#...
end

I've also used this in the past when I wanted to add an indeterminate number of filters to a sql statement. Sloppy I know, but it worked. :P
A better solution is not to make your page dependable on zoom settings. If you set limits like the one you are proposing, you are limiting accessibility. If someone cannot read your text well, they just won't be able to change that. I would use proper CSS to make it look nice in any zoom.
If your really insist, take a look at this question on how to detect zoom level using JavaScript (nightmare!): How to detect page zoom level in all modern browsers?
Check if the scrollable element is already scrolled to the top when trying to scroll up or to the bottom when trying to scroll down and then preventing the default action to stop the entire page from moving.
var touchStartEvent;
$('.scrollable').on({
touchstart: function(e) {
touchStartEvent = e;
},
touchmove: function(e) {
if ((e.originalEvent.pageY > touchStartEvent.originalEvent.pageY && this.scrollTop == 0) ||
(e.originalEvent.pageY < touchStartEvent.originalEvent.pageY && this.scrollTop + this.offsetHeight >= this.scrollHeight))
e.preventDefault();
}
});
Step by step localize Info.plist:
Save As
field write InfoPlist ONLY ("I" capital and "P" capital)"NSLocationAlwaysAndWhenInUseUsageDescription"="blabla";
"NSLocationAlwaysUsageDescription"="blabla2";
That's all work and you have localize your info.plist file!
Given below is a simple way to find exactly where in the list the item is.
for i in range (0,len(a)):
sublist=a[i]
for i in range(0,len(sublist)):
if search==sublist[i]:
print "found in sublist "+ "a"+str(i)
