With the YouTube video updated as of June 2020 it's very straight forward
You will get and .sbv file
After speaking with you in the comments, I believe that you can just do this using numpy/scipy. The ideas is to read the image in the numpy
3d-array and feed it into the variable.
from scipy import misc
import tensorflow as tf
img = misc.imread('01.png')
print img.shape # (32, 32, 3)
img_tf = tf.Variable(img)
print img_tf.get_shape().as_list() # [32, 32, 3]
Then you can run your graph:
init = tf.initialize_all_variables()
sess = tf.Session()
sess.run(init)
im = sess.run(img_tf)
and verify that it is the same:
import matplotlib.pyplot as plt
fig = plt.figure()
fig.add_subplot(1,2,1)
plt.imshow(im)
fig.add_subplot(1,2,2)
plt.imshow(img)
plt.show()
P.S. you mentioned: Since it's supposed to parallelize reading, it seems useful to know.
. To which I can say that rarely in data-analysis reading of the data is the bottleneck. Most of your time you will spend training your model.
Copy the local.properties to root folder and run again.
You're probably better off using an HtmlTextWriter
or an XMLWriter
than a plain StringWriter
. They will take care of escaping for you, as well as making sure the document is well-formed.
This page shows the basics of using the HtmlTextWriter
class, the gist of which being:
StringWriter stringWriter = new StringWriter();
using (HtmlTextWriter writer = new HtmlTextWriter(stringWriter))
{
writer.AddAttribute(HtmlTextWriterAttribute.Class, classValue);
writer.RenderBeginTag(HtmlTextWriterTag.Div); // Begin #1
writer.AddAttribute(HtmlTextWriterAttribute.Href, urlValue);
writer.RenderBeginTag(HtmlTextWriterTag.A); // Begin #2
writer.AddAttribute(HtmlTextWriterAttribute.Src, imageValue);
writer.AddAttribute(HtmlTextWriterAttribute.Width, "60");
writer.AddAttribute(HtmlTextWriterAttribute.Height, "60");
writer.AddAttribute(HtmlTextWriterAttribute.Alt, "");
writer.RenderBeginTag(HtmlTextWriterTag.Img); // Begin #3
writer.RenderEndTag(); // End #3
writer.Write(word);
writer.RenderEndTag(); // End #2
writer.RenderEndTag(); // End #1
}
// Return the result.
return stringWriter.ToString();
I just thought I'd share an alias that I'm using for this. It's based on non-interactive interactive rebase. To add it to your git, run this command (explanation given below):
git config --global alias.amend-to '!f() { SHA=`git rev-parse "$1"`; git commit --fixup "$SHA" && GIT_SEQUENCE_EDITOR=true git rebase --interactive --autosquash "$SHA^"; }; f'
Or, a version that can also handle unstaged files (by stashing and then un-stashing them):
git config --global alias.amend-to '!f() { SHA=`git rev-parse "$1"`; git stash -k && git commit --fixup "$SHA" && GIT_SEQUENCE_EDITOR=true git rebase --interactive --autosquash "$SHA^" && git stash pop; }; f'
The biggest advantage of this command is the fact that it's no-vim.
(1)given that there are no conflicts during rebase, of course
git amend-to <REV> # e.g.
git amend-to HEAD~1
git amend-to aaaa1111
The name amend-to
seems appropriate IMHO. Compare the flow with --amend
:
git add . && git commit --amend --no-edit
# vs
git add . && git amend-to <REV>
git config --global alias.<NAME> '!<COMMAND>'
- creates a global git alias named <NAME>
that will execute non-git command <COMMAND>
f() { <BODY> }; f
- an "anonymous" bash function.SHA=`git rev-parse "$1"`;
- converts the argument to git revision, and assigns the result to variable SHA
git commit --fixup "$SHA"
- fixup-commit for SHA
. See git-commit
docsGIT_SEQUENCE_EDITOR=true git rebase --interactive --autosquash "$SHA^"
git rebase --interactive "$SHA^"
part has been covered by other answers.--autosquash
is what's used in conjunction with git commit --fixup
, see git-rebase
docs for more infoGIT_SEQUENCE_EDITOR=true
is what makes the whole thing non-interactive. This hack I learned from this blog post.Definitely not the most correct way, but if you just need a quick solution to get the date without the time and you do not wish to use a third party library this should do
Date db = db.substring(0, 10) + db.substring(23,28);
I only needed the date for visual purposes and couldn't Joda so I substringed.
If you type "AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGG" this will produce:
AARRRRRRRRRRRRRRRRRRRR
RRGGGGGGGGGGGGGGGGGGGG
G
I have taken my example from a couple different websites on google. I have tested this on ff 5.0, IE 8.0, and Chrome 10. It works on all of them.
.wrapword {
white-space: -moz-pre-wrap !important; /* Mozilla, since 1999 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
white-space: pre-wrap; /* css-3 */
word-wrap: break-word; /* Internet Explorer 5.5+ */
white-space: -webkit-pre-wrap; /* Newer versions of Chrome/Safari*/
word-break: break-all;
white-space: normal;
}
<table style="table-layout:fixed; width:400px">
<tr>
<td class="wrapword"></td>
</tr>
</table>
You can get a NodeList to iterate through by using getElementsByTagName()
, like this:
var lis = document.getElementById("navbar").getElementsByTagName("li");
You can test it out here. This is a NodeList not an array, but it does have a .length
and you can iterate over it like an array.
The easiest way that I found to fix this is to uninstall everything then install a specific version of tensorflow-gpu:
pip uninstall tensorflow
pip uninstall tensorflow-gpu
pip install tensorflow-gpu==2.0.0
pip install tensorflow_hub
pip install tensorflow_datasets
You can check if this worked by adding the following code into a python file:
from __future__ import absolute_import, division, print_function, unicode_literals
import numpy as np
import tensorflow as tf
import tensorflow_hub as hub
import tensorflow_datasets as tfds
print("Version: ", tf.__version__)
print("Eager mode: ", tf.executing_eagerly())
print("Hub Version: ", hub.__version__)
print("GPU is", "available" if tf.config.experimental.list_physical_devices("GPU") else "NOT AVAILABLE")
Run the file and then the output should be something like this:
Version: 2.0.0
Eager mode: True
Hub Version: 0.7.0
GPU is available
Hope this helps
## list of columns

for i in l1:
for j in range(0, 8431): #rows = 8431
df[i][j] = int(df[i][j])
I recommend you to use this only with small data. This code has complexity of O(n^2).
I tried re-creating this, and .someclass.notip
was being generated for me but .someclass:not(.notip)
was not, for as long as I did not have the @mixin tip()
defined. Once I had that, it all worked.
http://sassmeister.com/gist/9775949
$dropdown-width: 100px;
$comp-tip: true;
@mixin tip($pos:right) {
}
@mixin dropdown-pos($pos:right) {
&:not(.notip) {
@if $comp-tip == true{
@if $pos == right {
top:$dropdown-width * -0.6;
background-color: #f00;
@include tip($pos:$pos);
}
}
}
&.notip {
@if $pos == right {
top: 0;
left:$dropdown-width * 0.8;
background-color: #00f;
}
}
}
.someclass { @include dropdown-pos(); }
EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'.
it what I get when I remove @mixin tip($pos:right) { }
Portability between Linux and Windows is a big headache, since Linux is a POSIX-conformant system with - generally - a proper, high quality toolchain for C, whereas Windows doesn't even provide a lot of functions in the C standard library.
However, if you want to stick to the standard, you can write something like this:
#include <stdio.h>
#include <stdlib.h>
FILE *f = fopen("textfile.txt", "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
fseek(f, 0, SEEK_SET); /* same as rewind(f); */
char *string = malloc(fsize + 1);
fread(string, 1, fsize, f);
fclose(f);
string[fsize] = 0;
Here string
will contain the contents of the text file as a properly 0-terminated C string. This code is just standard C, it's not POSIX-specific (although that it doesn't guarantee it will work/compile on Windows...)
for centos, just zlib didn't solve the problem.I did
sudo yum install zlib-devel.i686
if you are using any mobile suit like mobogenie or something that might also will make this issue. try killing that too from the task manager.
Note : i faced the same issue, tried the above solution. That didn't work, finally found out this solution.May useful for someone else!..
You should try SciPy. It has a bunch of useful scientific routines for example, "routines for computing integrals numerically, solving differential equations, optimization, and sparse matrices." It uses the superfast optimized NumPy for its number crunching. See here for installing.
Note that spatial.distance.cosine computes the distance, and not the similarity. So, you must subtract the value from 1 to get the similarity.
from scipy import spatial
dataSetI = [3, 45, 7, 2]
dataSetII = [2, 54, 13, 15]
result = 1 - spatial.distance.cosine(dataSetI, dataSetII)
df.to_html()
has a columns parameter.
Just pass the columns into the to_html()
method.
df.to_html(columns=['A','B','C','D','E','F','G'])
Here's how I do file upload in react using axios

this.onChange = this.onChange.bind(this)
this.fileUpload = this.fileUpload.bind(this)
}
onFormSubmit(e){
e.preventDefault() // Stop form submit
this.fileUpload(this.state.file).then((response)=>{
console.log(response.data);
})
}
onChange(e) {
this.setState({file:e.target.files[0]})
}
fileUpload(file){
const url = 'http://example.com/file-upload';
const formData = new FormData();
formData.append('file',file)
const config = {

<input type="file" onChange={this.onChange} />
<button type="submit">Upload</button>

)
}
}
export default SimpleReactFileUpload
Here's some code from Excel 2010 that may work. It has a couple specifics (like filtering bad-encode characters from titles) but it was designed to create multiple multi-series graphs from 4-dimensional data having both absolute and percentage-based data. Modify it how you like:

I tried with:

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/get_started"
android:src="@drawable/home_started"
style="?android:borderlessButtonStyle"
android:adjustViewBounds="true"
android:clickable="true"
android:elevation="5dp"
android:longClickable="true" />
and this worked. Please note on the line: style="?android:borderlessButtonStyle"
T
must be defined within the scope in which you are working. Therefore, what you have posted will work if your class is generic on T
:
public class MyClass<T>
{
private List<T> newList;
public List<T> NewList
{
get{return newList;}
set{newList = value;}
}
}
Otherwise, you have to use a defined type.
EDIT: Per @lKashef's request, following is how to have a List property:
private List<int> newList;
public List<int> NewList
{
get{return newList;}
set{newList = value;}
}
This can go within a non-generic class.
Edit 2: In response to your second question (in your edit), I would not recommend using a list for this type of data handling (if I am understanding you correctly). I would put the user settings in their own class (or struct, if you wish) and have a property of this type on your original class:
public class UserSettings
{
string FirstName { get; set; }
string LastName { get; set; }
// etc.
}
public class MyClass
{
string MyClassProperty1 { get; set; }
// etc.
UserSettings MySettings { get; set; }
}
This way, you have named properties that you can reference instead of an arbitrary index in a list. For example, you can reference MySettings.FirstName
as opposed to MySettingsList[0]
.
Let me know if you have any further questions.
EDIT 3: For the question in the comments, your property would be like this:
public class MyClass
{
public List<KeyValuePair<string, string>> MySettings { get; set; }
}
EDIT 4: Based on the question's edit 2, following is how I would use this:
public class MyClass
{
// note that this type of property declaration is called an "Automatic Property" and
// it means the same thing as you had written (the private backing variable is used behind the scenes, but you don't see it)
public List<KeyValuePair<string, string> MySettings { get; set; }
}
public class MyConsumingClass
{
public void MyMethod
{
MyClass myClass = new MyClass();
myClass.MySettings = new List<KeyValuePair<string, string>>();
myClass.MySettings.Add(new KeyValuePair<string, string>("SomeKeyValue", "SomeValue"));
// etc.
}
}
You mentioned that "the property still won't appear in the object's instance," and I am not sure what you mean. Does this property not appear in IntelliSense? Are you sure that you have created an instance of MyClass
(like myClass.MySettings
above), or are you trying to access it like a static property (like MyClass.MySettings
)?
Here is what worked for me (sugested by soulBit):
1) Restart using restart from the file menu
2) Once it started again, manually close and open it.
This is the simplest solution ever and it completely removes the annoying thing.
If you want a "Null, empty or white space" check, you can avoid unnecessary string manipulation with LTRIM
and RTRIM
like this.
IF COALESCE(PATINDEX('%[^ ]%', @parameter), 0) > 0
RAISERROR ...
I think, you need to check your proxy settings in "internet options". If you are using proxy/'hide ip' applications, this problem may be occurs.
You should use partial views. I use the following approach:
Use a view model so you're not passing your domain models to your views:
public class EditPersonViewModel
{
public int Id { get; set; } // this is only used to retrieve record from Db
public string Name { get; set; }
public string Age { get; set; }
}
In your PersonController:
[HttpGet] // this action result returns the partial containing the modal
public ActionResult EditPerson(int id)
{
var viewModel = new EditPersonViewModel();
viewModel.Id = id;
return PartialView("_EditPersonPartial", viewModel);
}
[HttpPost] // this action takes the viewModel from the modal
public ActionResult EditPerson(EditPersonViewModel viewModel)
{
if (ModelState.IsValid)
{
var toUpdate = personRepo.Find(viewModel.Id);
toUpdate.Name = viewModel.Name;
toUpdate.Age = viewModel.Age;
personRepo.InsertOrUpdate(toUpdate);
personRepo.Save();
return View("Index");
}
}
Next create a partial view called _EditPersonPartial
. This contains the modal header, body and footer. It also contains the Ajax form. It's strongly typed and takes in our view model.
@model Namespace.ViewModels.EditPersonViewModel
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Edit group member</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "list-of-people"
}))
{
@Html.ValidationSummary()
@Html.AntiForgeryToken()
<div class="modal-body">
@Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Name)
@Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Age)
</div>
<div class="modal-footer">
<button class="btn btn-inverse" type="submit">Save</button>
</div>
}
Now somewhere in your application, say another partial _peoplePartial.cshtml etc:
<div>
@foreach(var person in Model.People)
{
<button class="btn btn-primary edit-person" data-id="@person.PersonId">Edit</button>
}
</div>
// this is the modal definition
<div class="modal hide fade in" id="edit-person">
<div id="edit-person-container"></div>
</div>
<script type="text/javascript">
$(document).ready(function () {
$('.edit-person').click(function () {
var url = "/Person/EditPerson"; // the url to the controller
var id = $(this).attr('data-id'); // the id that's given to each button in the list
$.get(url + '/' + id, function (data) {
$('#edit-person-container').html(data);
$('#edit-person').modal('show');
});
});
});
</script>
Using jackson, you can do it as follows:
ObjectMapper mapper = new ObjectMapper();
String clientFilterJson = "";
try {
clientFilterJson = mapper.writeValueAsString(filterSaveModel);
} catch (IOException e) {
e.printStackTrace();
}
Alternative:
df.shape[1]
(df.shape[0]
is the number of rows)
private static final int TAKE_PICTURE = 1;
private Uri imageUri;
public void takePhoto(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, TAKE_PICTURE);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}
}
If you include the library System.Data.Entity
you can use an overload of the Include()
method which takes a lambda expression instead of a string. You can then Select()
over children with Linq expressions rather than string
paths.
return DatabaseContext.Applications
.Include(a => a.Children.Select(c => c.ChildRelationshipType));
None except @Akira Sendoh has answered how to actually get ALL docs. But even that solution crashes my ES 6.3 service without logs. The only thing that worked for me using the low-level elasticsearch-py
library was through scan helper that uses scroll()
api:
from elasticsearch.helpers import scan
doc_generator = scan(
es_obj,
query={"query": {"match_all": {}}},
index="my-index",
)
# use the generator to iterate, dont try to make a list or you will get out of RAM
for doc in doc_generator:
# use it somehow
However, the cleaner way nowadays seems to be through elasticsearch-dsl
library, that offers more abstract, cleaner calls, e.g: http://elasticsearch-dsl.readthedocs.io/en/latest/search_dsl.html#hits
Simple and better solution : %WINDIR%\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe MyProject.sln I make a bat file like this %WINDIR%\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe D:\GESTION-SOMECOPA\GestionCommercial\GestionCommercial.sln pause
Then I can see all errors and correct them. Because when you change the folder name (without spaces as seen above) you will have another problems. Visual Studio 2015 works fine after this.
Use compareWith
, A function to compare the option values with the selected values. see here: https://material.angular.io/components/select/api#MatSelect
For an object of the following structure:
listOfObjs = [{ name: 'john', id: '1'}, { name: 'jimmy', id: '2'},...]
Define markup like this:
<mat-form-field>
<mat-select
[compareWith]="compareObjects"
[(ngModel)]="obj">
<mat-option *ngFor="let obj of listOfObjs" [value]="obj">
{{ obj.name }}
</mat-option>
</mat-select>
</mat-form-field>
And define comparison function like this:
compareObjects(o1: any, o2: any): boolean {
return o1.name === o2.name && o1.id === o2.id;
}
To create user in MySQL/MariaDB 5.7.6 and higher, use CREATE USER
syntax:
CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'new_password';
then to grant all access to the database (e.g. my_db
), use GRANT
Syntax, e.g.
GRANT ALL ON my_db.* TO 'new_user'@'localhost';
Where ALL
(priv_type) can be replaced with specific privilege such as SELECT
, INSERT
, UPDATE
, ALTER
, etc.
Then to reload newly assigned permissions run:
FLUSH PRIVILEGES;
To run above commands, you need to run mysql
command and type them into prompt, then logout by quit
command or Ctrl-D.
To run from shell, use -e
parameter (replace SELECT 1
with one of above commands):
$ mysql -e "SELECT 1"
or print statement from the standard input:
$ echo "FOO STATEMENT" | mysql
If you've got Access denied with above, specify -u
(for user) and -p
(for password) parameters, or for long-term access set your credentials in ~/.my.cnf
, e.g.
[client]
user=root
password=root
For people not familiar with MySQL syntax, here are handy shell functions which are easy to remember and use (to use them, you need to load the shell functions included further down).
Here is example:
$ mysql-create-user admin mypass
| CREATE USER 'admin'@'localhost' IDENTIFIED BY 'mypass'
$ mysql-create-db foo
| CREATE DATABASE IF NOT EXISTS foo
$ mysql-grant-db admin foo
| GRANT ALL ON foo.* TO 'admin'@'localhost'
| FLUSH PRIVILEGES
$ mysql-show-grants admin
| SHOW GRANTS FOR 'admin'@'localhost'
| Grants for admin@localhost
| GRANT USAGE ON *.* TO 'admin'@'localhost' IDENTIFIED BY PASSWORD '*6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4' |
| GRANT ALL PRIVILEGES ON `foo`.* TO 'admin'@'localhost'
$ mysql-drop-user admin
| DROP USER 'admin'@'localhost'
$ mysql-drop-db foo
| DROP DATABASE IF EXISTS foo
To use above commands, you need to copy&paste the following functions into your rc file (e.g. .bash_profile
) and reload your shell or source the file. In this case just type source .bash_profile
:
# Create user in MySQL/MariaDB.

You can do :
System.out.println(nir[0].length);
But be aware that there's no real two-dimensional array in Java. Each "first level" array contains another array. Each of these arrays can be of different sizes. nir[0].length
isn't necessarily the same size as nir[1].length
.
T_STRING
is a bit of a misnomer. It does not refer to a quoted "string"
. It means a raw identifier was encountered. This can range from bare
words to leftover CONSTANT
or function names, forgotten unquoted strings, or any plain text.
This syntax error is most common for misquoted string values however. Any unescaped and stray "
or '
quote will form an invalid expression:
? ?
echo "<a href="http://example.com">click here</a>";
Syntax highlighting will make such mistakes super obvious. It's important to remember to use backslashes for escaping \"
double quotes, or \'
single quotes - depending on which was used as string enclosure.
"
double quotes.echo
/print
lines instead of escaping in and out. Better yet consider a HEREDOC section.
Another example is using PHP entry inside HTML code generated with PHP:
$text = '<div>some text with <?php echo 'some php entry' ?></div>'
This happens if $text
is large with many lines and developer does not see the whole PHP variable value and focus on the piece of code forgetting about its source. Example is here
See also What is the difference between single-quoted and double-quoted strings in PHP?.
If you miss a closing "
then a syntax error typically materializes later. An unterminated string will often consume a bit of code until the next intended string value:
?
echo "Some text", $a_variable, "and some runaway string ;
success("finished");
?
It's not just literal T_STRING
s which the parser may protest then. Another frequent variation is an Unexpected '>'
for unquoted literal HTML.
If you copy and paste code from a blog or website, you sometimes end up with invalid code. Typographic quotes aren't what PHP expects:
$text = ’Something something..’ + ”these ain't quotes”;
Typographic/smart quotes are Unicode symbols. PHP treats them as part of adjoining alphanumeric text. For example ”these
is interpreted as a constant identifier. But any following text literal is then seen as a bareword/T_STRING by the parser.
If you have an unterminated expression in previous lines, then any following statement or language construct gets seen as raw identifier:
?
func1()
function2();
PHP just can't know if you meant to run two functions after another, or if you meant to multiply their results, add them, compare them, or only run one ||
or the other.
<?xml
headers in PHP scriptsThis is rather uncommon. But if short_open_tags are enabled, then you can't begin your PHP scripts with an XML declaration:
?
<?xml version="1.0"?>
PHP will see the <?
and reclaim it for itself. It won't understand what the stray xml
was meant for. It'll get interpreted as constant. But the version
will be seen as another literal/constant. And since the parser can't make sense of two subsequent literals/values without an expression operator in between, that'll be a parser failure.
A most hideous cause for syntax errors are Unicode symbols, such as the non-breaking space. PHP allows Unicode characters as identifier names. If you get a T_STRING parser complaint for wholly unsuspicious code like:
<?php
print 123;
You need to break out another text editor. Or an hexeditor even. What looks like plain spaces and newlines here, may contain invisible constants. Java-based IDEs are sometimes oblivious to an UTF-8 BOM mangled within, zero-width spaces, paragraph separators, etc. Try to reedit everything, remove whitespace and add normal spaces back in.
You can narrow it down with with adding redundant ;
statement separators at each line start:
<?php
;print 123;
The extra ;
semicolon here will convert the preceding invisible character into an undefined constant reference (expression as statement). Which in return makes PHP produce a helpful notice.
Variables in PHP are represented by a dollar sign followed by the name of the variable.
The dollar sign ($
) is a sigil that marks the identifier as a name of a variable. Without this sigil, the identifier could be a language keyword or a constant.
This is a common error when the PHP code was "translated" from code written in another language (C, Java, JavaScript, etc.). In such cases, a declaration of the variable type (when the original code was written in a language that uses typed variables) could also sneak out and produce this error.
If you use \
in a string, it has a special meaning. This is called an "Escape Character" and normally tells the parser to take the next character literally.
Example: echo 'Jim said \'Hello\'';
will print Jim said 'hello'
If you escape the closing quote of a string, the closing quote will be taken literally and not as intended, i.e. as a printable quote as part of the string and not close the string. This will show as a parse error commonly after you open the next string or at the end of the script.
Very common error when specifiying paths in Windows: "C:\xampp\htdocs\"
is wrong. You need "C:\\xampp\\htdocs\\"
.
You need PHP =7.4 to use property typing such as:
public stdClass $obj;
Python lists
translate to JSON arrays
. What it is giving you is a perfectly valid JSON string that could be used in a Javascript application. To get what you expected, you would need to use a dict
:
>>> json.dumps({'apple': 'cat', 'banana':'dog', 'pear':'fish'})
'{"pear": "fish", "apple": "cat", "banana": "dog"}'
To define a checked exception you create a subclass (or hierarchy of subclasses) of java.lang.Exception
. For example:
public class FooException extends Exception {
public FooException() { super(); }
public FooException(String message) { super(message); }
public FooException(String message, Throwable cause) { super(message, cause); }
public FooException(Throwable cause) { super(cause); }
}
Methods that can potentially throw or propagate this exception must declare it:
public void calculate(int i) throws FooException, IOException;
... and code calling this method must either handle or propagate this exception (or both):
try {
int i = 5;
myObject.calculate(5);
} catch(FooException ex) {
// Print error and terminate application.
ex.printStackTrace();
System.exit(1);
} catch(IOException ex) {
// Rethrow as FooException.
throw new FooException(ex);
}
You'll notice in the above example that IOException
is caught and rethrown as FooException
. This is a common technique used to encapsulate exceptions (typically when implementing an API).
Sometimes there will be situations where you don't want to force every method to declare your exception implementation in its throws clause. In this case you can create an unchecked exception. An unchecked exception is any exception that extends java.lang.RuntimeException
(which itself is a subclass of java.lang.Exception
):
public class FooRuntimeException extends RuntimeException {
...
}
Methods can throw or propagate FooRuntimeException
exception without declaring it; e.g.
public void calculate(int i) {
if (i < 0) {
throw new FooRuntimeException("i < 0: " + i);
}
}
Unchecked exceptions are typically used to denote a programmer error, for example passing an invalid argument to a method or attempting to breach an array index bounds.
The java.lang.Throwable
class is the root of all errors and exceptions that can be thrown within Java. java.lang.Exception
and java.lang.Error
are both subclasses of Throwable
. Anything that subclasses Throwable
may be thrown or caught. However, it is typically bad practice to catch or throw Error
as this is used to denote errors internal to the JVM that cannot usually be "handled" by the programmer (e.g. OutOfMemoryError
). Likewise you should avoid catching Throwable
, which could result in you catching Error
s in addition to Exception
s.
If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900
If your date is text and you need to convert it then DATEVALUE
will do this:
Use the following import statement to import java.util.List
:
<%@ page import="java.util.List" %>
BTW, to import more than one class, use the following format:
<%@ page import="package1.myClass1,package2.myClass2,....,packageN.myClassN" %>
No, IIRC there is no getopt() on Windows.
Boost, however, has the program_options library... which works okay. It will seem like overkill at first, but it isn't terrible, especially considering it can handle setting program options in configuration files and environment variables in addition to command line options.
There's a module for that: https://www.npmjs.com/package/string-to-stream
var str = require('string-to-stream')
str('hi there').pipe(process.stdout) // => 'hi there'
This is easy to do in xml. Set your top container to be a LinearLayout and set the orientation attribute as you wish. Then inside of that place two linearlayouts that both have "fill parent" on width and height. Finally, set the weigth attribute of those two linearlayouts to 1.
For large vectors:
y = as.POSIXlt(date1)$year + 1900 # x$year : years since 1900
m = as.POSIXlt(date1)$mon + 1 # x$mon : 0–11
var selected=[];
$('#multipleSelect :selected').each(function(){
selected[$(this).val()]=$(this).text();
});
console.log(selected);
Yet another approch to this problem. The selected array will have the indexes as the option values and the each array item will have the text as its value.
for example
<select id="multipleSelect" multiple="multiple">
<option value="abc">Text 1</option>
<option value="def">Text 2</option>
<option value="ghi">Text 3</option>
</select>
if say option 1 and 2 are selected.
the selected array will be :
selected['abc']=1;
selected['def']=2.
Use r.URL.Query()
when you appending to existing query, if you are building new set of params use the url.Values
struct like so
package main
import (
"fmt"
"log"
"net/http"
"net/url"
"os"
)
func main() {
req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
if err != nil {
log.Print(err)
os.Exit(1)
}
// if you appending to existing query this works fine
q := req.URL.Query()
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
// or you can create new url.Values struct and encode that like so
q := url.Values{}
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
req.URL.RawQuery = q.Encode()
fmt.Println(req.URL.String())
// Output:
// http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}
I had to do something slightly different for a project I was working on: find the relative site-packages directory relative to the base install prefix. If the site-packages folder was in /usr/lib/python2.7/site-packages
, I wanted the /lib/python2.7/site-packages
part. I have, in fact, encountered systems where site-packages
was in /usr/lib64
, and the accepted answer did NOT work on those systems.
Similar to cheater's answer, my solution peeks deep into the guts of Distutils, to find the path that actually gets passed around inside setup.py
. It was such a pain to figure out that I don't want anyone to ever have to figure this out again.
import sys
import os
from distutils.command.install import INSTALL_SCHEMES
if os.name == 'nt':
scheme_key = 'nt'
else:
scheme_key = 'unix_prefix'
print(INSTALL_SCHEMES[scheme_key]['purelib'].replace('$py_version_short', (str.split(sys.version))[0][0:3]).replace('$base', ''))
That should print something like /Lib/site-packages
or /lib/python3.6/site-packages
.
Regarding this part:
When I convert it to UTF-8 without bom and close file, the file is again ANSI when I reopen.
The easiest solution is to avoid the problem entirely by properly configuring Notepad++.
Try Settings
-> Preferences
-> New document
-> Encoding
-> choose UTF-8
without BOM, and check Apply to opened ANSI files
.
That way all the opened ANSI files will be treated as UTF-8 without BOM.
For explanation what's going on, read the comments below this answer.
To fully learn about Unicode and UTF-8, read this excellent article from Joel Spolsky.
This also does seem to work, although W3C specifies it is not intended "for an external (typically non-HTML) application or interactive content"

My solution:
let isEmpty = (val) => {
let typeOfVal = typeof val;
switch(typeOfVal){
case 'object':
return (val.length == 0) || !Object.keys(val).length;
break;
case 'string':
let str = val.trim();
return str == '' || str == undefined;
break;
case 'number':
return val == '';
break;
default:
return val == '' || val == undefined;
}
};
console.log(isEmpty([1,2,4,5])); // false
console.log(isEmpty({id: 1, name: "Trung",age: 29})); // false
console.log(isEmpty('TrunvNV')); // false
console.log(isEmpty(8)); // false
console.log(isEmpty('')); // true
console.log(isEmpty(' ')); // true
console.log(isEmpty([])); // true
console.log(isEmpty({})); // true
Here is an example of what I would do. I hope it's what you're looking for.
char_array = c("foo_bar","bar_foo","apple","beer")
a = data.frame("data"=char_array,"data2"=1:4)
a$data = substr(a$data,1,nchar(a$data)-3)
a should now contain:
data data2
1 foo_ 1
2 bar_ 2
3 ap 3
4 b 4
Be careful, although android:onClick
XML seems to be a convenient way to handle click, the setOnClickListener
implementation do something additional than adding the onClickListener
. Indeed, it put the view property clickable
to true.
While it's might not be a problem on most Android implementations, according to the phone constructor, button is always default to clickable = true but other constructors on some phone model might have a default clickable = false on non Button views.
So setting the XML is not enough, you have to think all the time to add android:clickable="true"
on non button, and if you have a device where the default is clickable = true and you forget even once to put this XML attribute, you won't notice the problem at runtime but will get the feedback on the market when it will be in the hands of your customers !
In addition, we can never be sure about how proguard will obfuscate and rename XML attributes and class method, so not 100% safe that they will never have a bug one day.
So if you never want to have trouble and never think about it, it's better to use setOnClickListener
or libraries like ButterKnife with annotation @OnClick(R.id.button)

A stored function can be used within a query. You could then apply it to every row, or within a WHERE clause.
A procedure is executed using the CALL query.
I also underwent the same issue as Maven doesn't create the settings.xml
file under .m2
folder. What I did was the following and it works smoothly without any issues.
Go to the location where you maven was unzipped.
Direct to following path,
\apache-maven-3.0.4\conf\
and copy the settings.xml
file and paste it inside your .m2
folder.
Now create a maven project.
In Mathematica:
a = {1, 2, 3, 4, 5}
a[[ ? Length[a] Random[] ? ]]
Or, in recent versions, simply:
RandomChoice[a]
This received a down-vote, perhaps because it lacks explanation, so here one is:
Random[]
generates a pseudorandom float between 0 and 1. This is multiplied by the length of the list and then the ceiling function is used to round up to the next integer. This index is then extracted from a
.
Since hash table functionality is frequently done with rules in Mathematica, and rules are stored in lists, one might use:
a = {"Badger" -> 5, "Bird" -> 1, "Fox" -> 3, "Frog" -> 2, "Wolf" -> 4};
Use 51Degrees.com device detection solution to detect browser name, vendor and version.
First, follow the 4-step guide to incorporate device detector in to your project. When I say incorporate I mean download archive with PHP code and database file, extract them and include 2 files. That's all there is to do to incorporate.
Once that's done you can use the following properties to get browser information:
$_51d['BrowserName'] - Gives you the name of the browser (Safari, Molto, Motorola, MStarBrowser etc).
$_51d['BrowserVendor'] - Gives you the company who created browser.
$_51d['BrowserVersion'] - Version number of the browser
Error message looks like this
Error message => ORA-00001: unique constraint (schema.unique_constraint_name) violated
ORA-00001 occurs when: "a query tries to insert a "duplicate" row in a table". It makes an unique constraint to fail, consequently query fails and row is NOT added to the table."
Solution:
Find all columns used in unique_constraint, for instance column a, column b, column c, column d collectively creates unique_constraint and then find the record from source data which is duplicate, using following queries:
-- to find <<owner of the table>> and <<name of the table>> for unique_constraint
select *
from DBA_CONSTRAINTS
where CONSTRAINT_NAME = '<unique_constraint_name>';
Then use Justin Cave's query (pasted below) to find all columns used in unique_constraint:
SELECT column_name, position
FROM all_cons_columns
WHERE constraint_name = <<name of constraint from the error message>>
AND owner = <<owner of the table>>
AND table_name = <<name of the table>>
-- to find duplicates
select column a, column b, column c, column d
from table
group by column a, column b, column c, column d
having count (<any one column used in constraint > ) > 1;
you can either delete that duplicate record from your source data (which was a select query in my particular case, as I experienced it with "Insert into select") or modify to make it unique or change the constraint.
With dplyr 0.7.2
, you can use the very useful case_when
function :
x=read.table(
text="V1 V2 V3 V4
1 1 2 3 5
2 2 4 4 1
3 1 4 1 1
4 4 5 1 3
5 5 5 5 4")
x$V5 = case_when(x$V1==1 & x$V2!=4 ~ 1,
x$V2==4 & x$V3!=1 ~ 2,
TRUE ~ 0)
Expressed with dplyr::mutate
, it gives:
x = x %>% mutate(
V5 = case_when(
V1==1 & V2!=4 ~ 1,
V2==4 & V3!=1 ~ 2,
TRUE ~ 0
)
)
Please note that NA
are not treated specially, as it can be misleading. The function will return NA
only when no condition is matched. If you put a line with TRUE ~ ...
, like I did in my example, the return value will then never be NA
.
Therefore, you have to expressively tell case_when
to put NA
where it belongs by adding a statement like is.na(x$V1) | is.na(x$V3) ~ NA_integer_
. Hint: the dplyr::coalesce()
function can be really useful here sometimes!
Moreover, please note that NA
alone will usually not work, you have to put special NA
values : NA_integer_
, NA_character_
or NA_real_
.
Start observing 'input' event instead of 'change'.
jQuery('#some_text_box').on('input', function() {
// do your stuff
});
...which is nice and clean, but may be extended further to:
jQuery('#some_text_box').on('input propertychange paste', function() {
// do your stuff
});
In addition, for those looking to replace more than one character in a column, you can do it using regular expressions:
import re
chars_to_remove = ['.', '-', '(', ')', '']
regular_expression = '[' + re.escape (''. join (chars_to_remove)) + ']'
df['string_col'].str.replace(regular_expression, '', regex=True)
Your browser is sitting on top of TCP/IP, as the web is based on standards, usually port 80, what happens is when you enter an address, such as google.com, your computer where the browser is running on, creates packets of data, encapsulated at each layer accordingly to the OSI standards, (think of envelopes of different sizes, packed into each envelope of next size), OSI defines 7 layers, in one of the envelopes contains the source address and destination address(that is the website) encoded in binary.
As it reaches the 1st layer, in OSI terms, it gets transmitted across the media transmitter (such as cable, DSL).
If you are connected via ISP, the layered pack of envelopes gets transmitted to the ISP, the ISP's network system, peeks through the layered pack of envelopes by decoding in reverse order to find out the address, then the ISP checks their Domain Name System database to find out if they have a route to that address (cached in memory, if it does, it forwards it across the internet network - again layered pack of envelopes).
If it doesn't, the ISP interrogates the top level DNS server to say 'Hey, get me the route for the address as supplied by you, ie. the browser', the top level DNS server then passes the route to the ISP which is then stored in the ISP's server memory.
The layered pack of envelopes are transmitted and received by the website server after successful routing of the packets (think of routing as signposts for directions to get to the server), which in turn, unpacks the layered pack of envelopes, extracts the source address and says 'Aha, that is for me, right, I know the destination address (that is you, the browser), then the server packetizes the webpages into a packed layered envelopes and sends it back (usually in reverse route, but not always the case).
Your browser than receives the packetized envelopes and unpacks each of them. Then your computer descrambles the data and your browser renders the pages on the screen.
I hope this answer is sufficient enough for your understanding.
You can use:
function encodeHTML(str){
var aStr = str.split(''),
i = aStr.length,
aRet = [];
while (i--) {
var iC = aStr[i].charCodeAt();
if (iC < 65 || iC > 127 || (iC>90 && iC<97)) {
aRet.push('&#'+iC+';');
} else {
aRet.push(aStr[i]);
}
}
return aRet.reverse().join('');
}
This function HTMLEncodes everything that is not a-z/A-Z.
[Edit] A rather old answer. Let's add a simpler String extension to encode all extended characters:
String.prototype.encodeHTML = function () {
return this.replace(/[\u0080-\u024F]/g,
function (v) {return '&#'+v.charCodeAt()+';';}
);
}
// usage
log('Übergroße Äpfel mit Würmern'.encodeHTML());
//=> 'Übergroße Äpfel mit Würmern'
You can download the 10.7 Lion JDK from http://connect.apple.com.
Sign in and click the java
section on the right.
The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.
At the time of writing the JDK ended up here:
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Open up eclipse preferences and go to Java --> Installed JREs page
Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location
At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button
From the Add JRE wizard choose "MacOS X VM" for the JRE Type
For the JRE Definition Page we need to fill in the following:
The other fields will now auto fill, with the default JRE name being "Home". You can quickly correct this to something more meaningful:
Finish the wizard and return to the Installed JREs page
Choose "System JDK" from the list
You can now develop normally with:
The simplest option is to use a global variable. Then create a function that gets the current word.
current_word = ''
def oneFunction(lists):
global current_word
word=random.choice(lists[category])
current_word = word
def anotherFunction():
for letter in get_word():
print("_",end=" ")
def get_word():
return current_word
The advantage of this is that maybe your functions are in different modules and need to access the variable.
How about:
SELECT <column>, count(*)
FROM <table>
GROUP BY <column> HAVING COUNT(*) > 1;
To answer the example above, it would look like:
SELECT job_number, count(*)
FROM jobs
GROUP BY job_number HAVING COUNT(*) > 1;
How will the browser know when to run the code inside script tag? So, to make the code run after the window is loaded completely,
window.onload = doStuff;
function doStuff() {
var e = document.getElementById("db_info");
e.innerHTML='Found you';
}
The other alternative is to keep your <script...</script>
just before the closing </body>
tag.

To get last week's data in MySQL. This works for me even across the year boundries.
select * from orders_order where YEARWEEK(my_date_field)= YEARWEEK(DATE_SUB(CURRENT_DATE(), INTERVAL 1 WEEK));
To get current week's data
select * from orders_order where YEARWEEK(date_sold)= YEARWEEK(CURRENT_DATE());
This works well since all the inputs have to meet the condition of not null.
$(function () {
$('#submits').attr('disabled', true);
$('#input_5').change(function () {
if ($('#input_1').val() != '' && $('#input_2').val() != '' && $('#input_3').val() != '' && $('#input_4').val() != '' && $('#input_5').val() != '') {
$('#submit').attr('disabled', false);
} else {
$('#submit').attr('disabled', true);
}
});
});

unless Executor (thread pool) is used in which case, the value of 'maxThreads' from Executor will be used instead. For Non-blocking IO, it doesn't seem to be dependent on maxThreads
.
I don't have enough rep here to add this as a comment, but IMO it's good style to write your headers with #include guards anyway, which as noted by Paranaix a few hours ago would prevent a multiple-definition error. Unless you're already using a separate CPP file, it's not necessary to use one just to initialize static non-integral members.
#ifndef FOO_H
#define FOO_H
#include "bar.h"
class foo
{
private:
static bar i;
};
bar foo::i = VALUE;
#endif
I see no need to use a separate CPP file for this. Sure, you can, but there's no technical reason why you should have to.
Using Base64 string in JSON will be very heavy. The parser has to do a lot of heavy lifting. Currently, Fresco only supports base supports Base64. Better you put something on Amazon Cloud or Firebase Cloud. And get an image as a URL. So that you can use Picasso or Glide for caching.
It's quite unclear how you are computing the size ("the size in debug mode"?").
Use printf()
:
printf("the size of c is %u\n", (unsigned int) sizeof c);
Normally you'd print a size_t
value (which is the type sizeof
returns) with %zu
, but if you're using a pre-C99 compiler like Visual Studio that won't work.
You need to find the typedef
statements in your code that define the custom names like uint8
and so on; those are not standard so nobody here can know how they're defined in your code.
New C code should use <stdint.h>
which gives you uint8_t
and so on.
"1" + "2" + "3"
or
["1", "2", "3"].join("")
The join method concatenates the items of an array into a string, putting the specified delimiter between items. In this case, the "delimiter" is an empty string (""
).
parseInt("123")
Prior to ECMAScript 5, it was necessary to pass the radix for base 10: parseInt("123", 10)
123 + 100
(223).toString()
(parseInt("1" + "2" + "3") + 100).toString()
or
(parseInt(["1", "2", "3"].join("")) + 100).toString()
I started with this book: Relational Database Design Clearly Explained (The Morgan Kaufmann Series in Data Management Systems) (Paperback) by Jan L. Harrington and found it very clear and helpful
and as you get up to speed this one was good too Database Systems: A Practical Approach to Design, Implementation and Management (International Computer Science Series) (Paperback)
I think SQL and database design are different (but complementary) skills.
This is a little outdated, by Ryan Bigg does a great job explaining this here:
http://ryanbigg.com/2009/04/how-rails-works-2-mime-types-respond_to
In fact, it might be a bit more detail than you were looking for. As it turns out, there's a lot going on behind the scenes, including a need to understand how the MIME types get loaded.
Try:
h1 {
margin-top: 0;
}
You're seeing the effects of margin collapsing.
I came across System.Runtime.InteropServices.COMException
while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM
Methods. I ran Visual Studio as Administrator and the exception was gone.
if you want to add directly to input as attribute, use this
onclick="return false;"
<input id = "btnPlay" type="button" onclick="return false;" value="play" />
this will prevent form submit behaviour
The trunk is the main line of development in a SVN repository.
A branch is a side-line of development created to make larger, experimental or disrupting work without annoying users of the trunk version. Also, branches can be used to create development lines for multiple versions of the same product, like having a place to backport bugfixes into a stable release.
Finally, tags are markers to highlight notable revisions in the history of the repository, usually things like "this was released as 1.0".
See the HTML version of "Version Control with Subversion", especially Chapter 4: Branching and Merging or buy it in paper (e.g. from amazon) for an in-depth discussion of the technical details.
As others (e.g. Peter Neubauer below) the underlying implementation as /tags
/branches
and /trunk
directories is only conventional and not in any way enforced by the tools. Violating these conventions leads to confusion all around, as this breaks habits and expectations of others accessing the repository. Special care must be taken to avoid committing new changes into tags, which should be frozen.
I use TortoiseSVN but no Visual Studio integration. I keep the "Check for modifications" dialog open on the second monitor the whole time, so I can track which files I have touched. But see the "Best SVN Tools" question, for more recommendations.
My fix is more simple, create a factory, and implement as one variable. For example
angular.module('myApp', [])_x000D_
_x000D_
// This a searchCustom factory. Copy the factory and implement in the controller_x000D_
.factory("searchCustom", function($http,$log){ _x000D_

Streams are EventEmitter
s so you can listen to certain events. As you said there is a finish
event for request (previously end
).
var stream = request(...).pipe(...);
stream.on('finish', function () { ... });
For more information about which events are available you can check the stream documentation page.
Try Like this.
For Inserting into DB
$db = mysqli_connect("localhost","root","","DbName"); //keep your db name
$image = addslashes(file_get_contents($_FILES['images']['tmp_name']));
//you keep your column name setting for insertion. I keep image type Blob.
$query = "INSERT INTO products (id,image) VALUES('','$image')";
$qry = mysqli_query($db, $query);
For Accessing image From Blob
$db = mysqli_connect("localhost","root","","DbName"); //keep your db name
$sql = "SELECT * FROM products WHERE id = $id";
$sth = $db->query($sql);
$result=mysqli_fetch_array($sth);
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result['image'] ).'"/>';
Hope It will help you.
Thanks.
(Angular 2 - Angular 7)
Component can be declared in a single module only. In order to use a component from another module, you need to do two simple tasks:
1st Module:
Have a component (lets call it: "ImportantCopmonent"), we want to re-use in the 2nd Module's page.
@NgModule({
declarations: [
FirstPage,
ImportantCopmonent // <-- Enable using the component html tag in current module
],
imports: [
IonicPageModule.forChild(NotImportantPage),
TranslateModule.forChild(),
],
exports: [
FirstPage,
ImportantCopmonent // <--- Enable using the component in other modules
]
})
export class FirstPageModule { }
2nd Module:
Reuses the "ImportantCopmonent", by importing the FirstPageModule
@NgModule({
declarations: [
SecondPage,
Example2ndComponent,
Example3rdComponent
],
imports: [
IonicPageModule.forChild(SecondPage),
TranslateModule.forChild(),
FirstPageModule // <--- this Imports the source module, with its exports
],
exports: [
SecondPage,
]
})
export class SecondPageModule { }
One addendum to the excellent answers above, on a point that confused me even after I had read Stroustrup and thought I understood the rvalue/lvalue distinction. When you see
int&& a = 3
,
it's very tempting to read the int&&
as a type and conclude that a
is an rvalue. It's not:
int&& a = 3;
int&& c = a; //error: cannot bind 'int' lvalue to 'int&&'
int& b = a; //compiles
a
has a name and is ipso facto an lvalue. Don't think of the &&
as part of the type of a
; it's just something telling you what a
is allowed to bind to.
This matters particularly for T&&
type arguments in constructors. If you write
Foo::Foo(T&& _t) : t{_t} {}
you will copy _t
into t
. You need
Foo::Foo(T&& _t) : t{std::move(_t)} {}
if you want to move. Would that my compiler warned me when I left out the move
!
Is the recommendation to include CSS before JavaScript invalid?
Not if you treat it as simply a recommendation. But if your treat it as a hard and fast rule?, yes, it is invalid.
From https://developer.mozilla.org/en-US/docs/Web/Reference/Events/DOMContentLoaded
Stylesheet loads block script execution, so if you have a
<script>
after a<link rel="stylesheet" ...>
the page will not finish parsing - and DOMContentLoaded will not fire - until the stylesheet is loaded.
It appears that you need to know what each script relies on and make sure that execution of the script is delayed until after the right completion event. If the script relies only on the DOM, it can resume in ondomready/domcontentloaded, if it relies on images to be loaded or stylesheets to be applied, then if I read the above reference correctly, that code must be deferred until the onload event.
I don't think that one sock size fits all, even though that is the way they are sold and I know that one shoe size does not fit all. I don't think that there is a definitive answer to which to load first, styles or script. It is more a case by case decision of what must be loaded in what order and what can be deferred until later as not being on the "critical path".
To speak to the observer that commented that it is better to delay the users ability to interact until the sheet is pretty. There are many of you out there and you annoy your counterparts that feel the opposite. They came to a site to accomplish a purpose and delays to their ability to interact with a site while waiting for things that don't matter to finish loading are very frustrating. I am not saying that you are wrong, only that you should be aware that there is another faction that exists that does not share your priority.
This question particularly applies to all of the ads being placed on web sites. I would love it if site authors rendered just placeholder divs for the ad content and made sure that their site was loaded and interactive before injecting the ads in an onload event. Even then I would like to see the ads loaded serially instead of all at once because they impact my ability to even scroll the site content while the bloated ads are loading. But that is just one persons point of view.
I think that what you are stating as the "difference" is actually a consequence of the real difference.
The actual difference is the target of the code written. Who is going to run this code.
A scripting language is used to write code that is going to target a software system. It's going to automate operations on that software system. The script is going to be a sequence of instructions to the target software system.
A programming language targets the computing system, which can be a real or virtual machine. The instructions are executed by the machine.
Of course, a real machine understands only binary code so you need to compile the code of a programming language. But this is a consequence of targeting a machine instead of a program.
In the other hand, the target software system of an script may compile the code or interpret it. Is up to the software system.
If we say that the real difference is whether it is compiled or not, then we have a problem because when Javascript runs in V8 is compiled and when it runs in Rhino is not.
It gets more confusing since scripting languages have evolved to become very powerful. So they are not limited to create small scripts to automate operations on another software system, you can create any rich applications with them.
Python code targets an interpreter so we can say that it "scripts" operations on that interpreter. But when you write Python code you don't see it as scripting an interpreter, you see it as creating an application. The interpreter is just there to code at a higher level among other things. So for me Python is more a programming language than an scripting language.
This is what I went with. For those of you who want to optimize, check out https://stackoverflow.com/a/624379/991863.

If you intend to read the data only from the client-side, you can use the local storage. It's deleted only when the browser's cache is cleared.
if you want to kill a specific node process , you can go to command line route and type:
ps aux | grep node
to get a list of all node process ids. now you can get your process id(pid), then do:
kill -9 PID
and if you want to kill all node processes then do:
killall -9 node
-9 switch is like end task on windows. it will force the process to end. you can do:
kill -l
to see all switches of kill command and their comments.
Taking the answer from @Petr Stastny a step further by adding a password variable. I'd prefer if it actually took it in like a regular password rather than as an argument, but it's working for what I needed.
#!/bin/bash
# mycollate.sh <database> <password> [<charset> <collation>]
# changes MySQL/MariaDB charset and collation for one database - all tables and
# all columns in all tables
DB="$1"
PW="$2"
CHARSET="$3"
COLL="$4"
[ -n "$DB" ] || exit 1
[ -n "$PW" ]
[ -n "$CHARSET" ] || CHARSET="utf8mb4"
[ -n "$COLL" ] || COLL="utf8mb4_bin"
PW="--password=""$PW"
echo $DB
echo "ALTER DATABASE $DB CHARACTER SET $CHARSET COLLATE $COLL;" | mysql -u root "$PW"
echo "USE $DB; SHOW TABLES;" | mysql -s "$PW" | (
while read TABLE; do
echo $DB.$TABLE
echo "ALTER TABLE $TABLE CONVERT TO CHARACTER SET $CHARSET COLLATE $COLL;" | mysql "$PW" $DB
done
)
PW="pleaseEmptyMeNow"
Both of the following code will work fine for removing highchart.com from the chart:-
credits: false
or
credits:{
enabled:false,
}
You can use for loop to find your element and update it:
updateItem(newItem){
for (let i = 0; i < this.itemsArray.length; i++) {
if(this.itemsArray[i].id == newItem.id){
this.users[i] = newItem;
}
}
}
To cover the entire viewport, you can use:
<iframe src="mypage.html" style="position:fixed; top:0; left:0; bottom:0; right:0; width:100%; height:100%; border:none; margin:0; padding:0; overflow:hidden; z-index:999999;">
Your browser doesn't support iframes
</iframe>
And be sure to set the framed page's margins to 0, e.g., - Actually, this is not necessary with this solution.body { margin: 0; }
.
I am using this successfully, with an additional display:none
and JS to show it when the user clicks the appropriate control.
Note: To fill the parent's view area instead of the entire viewport, change position:fixed
to position:absolute
.
You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:
In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file"
field, ostensibly for backward compatibility reasons.
So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.
public static int convBool(boolean b)
{
int convBool = 0;
if(b) convBool = 1;
return convBool;
}
Then use :
convBool(aBool);
Anytime you're changing the headers of an HttpWebRequest
, you need to use the appropriate properties on the object itself, if they exist. If you have a plain WebRequest
, be sure to cast it to an HttpWebRequest
first. Then Referrer
in your case can be accessed via ((HttpWebRequest)request).Referrer
, so you don't need to modify the header directly - just set the property to the right value. ContentLength
, ContentType
, UserAgent
, etc, all need to be set this way.
IMHO, this is a shortcoming on MS part...setting the headers via Headers.Add()
should automatically call the appropriate property behind the scenes, if that's what they want to do.

Hello year 2010 question.
The OP.'s requirement is preserve keys (keep keys) and not overlap (I think overwrite). In some case such as numeric keys it is possible but if string keys it seems to be not possible.
If you use array_merge()
the numeric keys will always re-index or renumbered.
If you use array_replace()
, array_replace_recursive()
it will be overlap or overwrite from the right to the left. The value with the same key on first array will be replaced with second array.
If you use $array1 + $array2
as the comment was mentioned, if the keys are same then it will keep the value from first array but drop the second array.
Here is my function that I just wrote to work on the same requirements. You are free to use for any purpose.
/**
* Array custom merge. Preserve indexed array key (numbers) but overwrite string key (same as PHP's `array_merge()` function).
*
* If the another array key is string, it will be overwrite the first array.<br>
* If the another array key is integer, it will be add to first array depend on duplicated key or not.
* If it is not duplicate key with the first, the key will be preserve and add to the first array.
* If it is duplicated then it will be re-index the number append to the first array.
*
* @param array $array1 The first array is main array.
* @param array ...$arrays The another arrays to merge with the first.
* @return array Return merged array.

$array1[$key] = $item;
} elseif (is_int($key) && !array_key_exists($key, $array1)) {
// if key is number. this should be indexed array.
// and if array 1 is not already has this key.
// add this array with the key preserved to array 1.
$array1[$key] = $item;
} else {
// if anything else...
// get all keys from array 1 (numbers only).
$array1Keys = array_filter(array_keys($array1), 'is_int');
// next key index = get max array key number + 1.
$nextKeyIndex = (intval(max($array1Keys)) + 1);
unset($array1Keys);

If the base class is Base
, and a derived class is Der
, you can have a Base *p
pointer which actually points to an instance of Der
. When you call p->foo();
, if foo
is not virtual, then Base
's version of it executes, ignoring the fact that p
actually points to a Der
. If foo is virtual, p->foo()
executes the "leafmost" override of foo
, fully taking into account the actual class of the pointed-to item. So the difference between virtual and non-virtual is actually pretty crucial: the former allows runtime polymorphism, the core concept of OO programming, while the latter does not.
Yes. For that ensure that you declare the worksheet
For example
Previous Code
Sub Sample()
Dim ws As Worksheet
Set ws = Sheets("Sheet3")
Debug.Print ws.Cells(23, 4).Value
End Sub
New Code
Sub Sample()
Dim ws As Worksheet
Set ws = Sheets("Sheet4")
Debug.Print ws.Cells(23, 4).Value

Here's a compact way to do something different in all four cases:
if(empty($youtube)) {
if(empty($link)) {
# both empty
} else {
# only $youtube not empty
}
} else {
if(empty($link)) {
# only $link empty
} else {
# both not empty
}
}
If you want to use an expression instead, you can use ?:
instead:
echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
: ( empty($link) ? 'only $link empty' : 'both not empty' );
If you are 100% sure $message contain ISO-8859-1 you can use utf8_encode as David says. Otherwise use mb_detect_encoding and mb_convert_encoding on $message.
Also take note that
$mail -> charSet = "UTF-8";
Should be replaced by:
$mail->CharSet = 'UTF-8';
And placed after the instantiation of the class (after the new
). The properties are case sensitive! See the PHPMailer doc fot the list & exact spelling.
Also the default encoding of PHPMailer is 8bit
which can be problematic with UTF-8 data. To fix this you can do:
$mail->Encoding = 'base64';
Take note that 'quoted-printable'
would probably work too in these cases (and maybe even 'binary'
). For more details you can read RFC1341 - Content-Transfer-Encoding Header Field.
I assume I have import datetime
before running each of the lines of code below
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
prints "01/25/13"
.
If you can't live with the leading zero, try this:
dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)
This prints "1/25/13"
.
EDIT: This may not work on every platform:
datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')
You do not need a Javascript code for that...
I think you mean the placeholder attribute. Here is the code:
<input type="text" placeholder="Your descriptive text goes here...">
The default text will be grey-ish and when clicked, it will dissapear!
Here is what worked for me
Set editable to false
<EditText android:id="@+id/dob"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Date of Birth"
android:inputType="none"
android:editable="false"
/>
Then add an event listener for OnFocusChange
private View.OnFocusChangeListener onFocusChangeDOB= new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus){
showDialog(DATE_DIALOG_ID);
}
}
};
A MonkeyPatch is a piece of Python code which extends or modifies other code at runtime (typically at startup).
A simple example looks like this:
from SomeOtherProduct.SomeModule import SomeClass
def speak(self):
return "ook ook eee eee eee!"
SomeClass.speak = speak
Source: MonkeyPatch page on Zope wiki.
Try this query it ll change the records ends with .com
UPDATE tablename SET email = replace(email, '.com', '.org') WHERE email LIKE '%.com';
for fish shell user
set --universal fish_user_paths $fish_user_paths ~/.rbenv/shims/
You Need to take same height and width
and simply use the border-radius:360px;
just use a subquery right there like:
INSERT INTO table1 VALUES ("A string", 5, (SELECT ...)).
The problem is described (among other) in this article.
#box
is relatively positioned, which makes it part of the "flow" of the page. Your other divs are absolutely positioned, so they are removed from the page's "flow".
Page flow means that the positioning of an element effects other elements in the flow.
In other words, as #box
now sees the dom, .a and .b are no longer "inside" #box
.
To fix this, you would want to make everything relative, or everything absolute.
One way would be:
.a {
position:relative;
margin-top:10px;
margin-left:10px;
background-color:red;
width:210px;
padding: 5px;
}
You can use a separate class to represent the JSON object and use @SerializedName
annotations to specify the field name to grab for each data member:
public class Response {
@SerializedName("data")
private Data data;
private static class Data {
@SerializedName("translations")
public Translation[] translations;
}
private static class Translation {
@SerializedName("translatedText")
public String translatedText;
}
public String getTranslatedText() {
return data.translations[0].translatedText;
}
}
Then you can do the parsing in your parse() method using a Gson
object:
Gson gson = new Gson();
Response response = gson.fromJson(jsonLine, Response.class);
System.out.println("Translated text: " + response.getTranslatedText());
With this approach, you can reuse the Response
class to add any other additional fields to pick up other data members you might want to extract from JSON -- in case you want to make changes to get results for, say, multiple translations in one call, or to get an additional string for the detected source language.
The key here is to get the first day of the month. For that, there are several options. In terms of performance, our tests show that there isn't a significant difference between them - we wrote a whole blog article on the topic. Our findings show that what really matters is whether you need the result to be VARCHAR, DATETIME, or DATE.
The fastest solution to the real problem of getting the first day of the month returns VARCHAR:
SELECT CONCAT(LEFT(CURRENT_DATE, 7), '-01') AS first_day_of_month;
The second fastest solution gives a DATETIME result - this runs about 3x slower than the previous:
SELECT TIMESTAMP(CONCAT(LEFT(CURRENT_DATE, 7), '-01')) AS first_day_of_month;
The slowest solutions return DATE objects. Don't believe me? Run this SQL Fiddle and see for yourself
In your case, since you need to compare the value with other DATE values in your table, it doesn't really matter what methodology you use because MySQL will do the conversion implicitly even if your formula doesn't return a DATE object.
So really, take your pick. Which is most readable for you? I'd pick the first since it's the shortest and arguably the simplest:
SELECT * FROM table_name
WHERE date BETWEEN CONCAT(LEFT(CURRENT_DATE, 7), '-01') AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN DATE(CONCAT(LEFT(CURRENT_DATE, 7), '-01')) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN (LAST_DAY(CURRENT_DATE) + INTERVAL 1 DAY - INTERVAL 1 MONTH) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN (DATE(CURRENT_DATE) - INTERVAL (DAYOFMONTH(CURRENT_DATE) - 1) DAY) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN (DATE(CURRENT_DATE) - INTERVAL (DAYOFMONTH(CURRENT_DATE)) DAY + INTERVAL 1 DAY) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN DATE_FORMAT(CURRENT_DATE,'%Y-%m-01') AND CURDATE;
SQLite doesn't have dedicated datetime types, but does have a few datetime functions. Follow the string representation formats (actually only formats 1-10) understood by those functions (storing the value as a string) and then you can use them, plus lexicographical comparison on the strings will match datetime comparison (as long as you don't try to compare dates to times or datetimes to times, which doesn't make a whole lot of sense anyway).
Depending on which language you use, you can even get automatic conversion. (Which doesn't apply to comparisons in SQL statements like the example, but will make your life easier.)
Don't know if it's worth adding another answer, but just in case...
I had to hunt this down in a couple places but finally got this version of the code to work.
strings.xml:
<string name="name1"><a href="http://www.google.com">link text1</a></string>
<string name="name2"><a href="http://www.google.com">link text2</a></string>
myactivity.xml:
<TextView
android:id="@+id/textview1"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginTop="5dp" />
<TextView
android:id="@+id/textview2"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginTop="5dp" />
myactivty.java (in onCreate()):
TextView tv1 = (TextView)findViewById(R.id.textview1);
TextView tv2 = (TextView)findViewById(R.id.textview2);
tv1.setText(Html.fromHtml(getResources().getString(R.string.name1)));
tv2.setText(Html.fromHtml(getResources().getString(R.string.name2)));
tv1.setMovementMethod(LinkMovementMethod.getInstance());
tv2.setMovementMethod(LinkMovementMethod.getInstance());
This will create two clickable hyperlinks with the text link text1
and link text2
which redirect the user to google.
If your column data type is 'text' then you will get an error message as
Msg 8116, Level 16, State 1, Line 2 Argument data type text is invalid for argument 1 of replace function.
In this case you need to cast the text as nvarchar and then replace
SELECT REPLACE(REPLACE(cast(@str as nvarchar(max)), CHAR(13), ''), CHAR(10), '')
Here is what I'm using:
if (mySQLConnection.State != ConnectionState.Open)
{
mySQLConnection.Close();
mySQLConnection.Open();
}
The reason I'm not simply using:
if (mySQLConnection.State == ConnectionState.Closed)
{
mySQLConnection.Open();
}
Is because the ConnectionState can also be:
Broken, Connnecting, Executing, Fetching
In addition to
Open, Closed
Additionally Microsoft states that Closing, and then Re-opening the connection "will refresh the value of State." See here http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.state(v=vs.110).aspx
You may create a new list with an input of a previous list like so:
List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);
This will allow you to modify the order or what elemtents are contained independent of the first list.
Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.
example:
MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"
Edit
To avoid this you need a deep copy of each element in the list like so:
List<Torero> one = new ArrayList<Torero>();
//add elements
List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
Torero copy = deepCopy(t);
two.add(copy);
}
with copy like the following:
public Torero deepCopy(Torero input){
Torero copy = new Torero();
copy.setValue(input.getValue());//.. copy primitives, deep copy objects again
return copy;
}

You may also return to the previous state of the local repo in another way:
git add
. git reset --hard
.I think the best way I've seen it done is multiplying by 10 to the power of the number of digits, then doing a Math.round, then finally dividing by 10 to the power of digits. Here is a simple function I use in typescript:
function roundToXDigits(value: number, digits: number) {
value = value * Math.pow(10, digits);
value = Math.round(value);
value = value / Math.pow(10, digits);
return value;
}
Or plain javascript:
function roundToXDigits(value, digits) {
if(!digits){
digits = 2;
}
value = value * Math.pow(10, digits);
value = Math.round(value);
value = value / Math.pow(10, digits);
return value;
}
d = {1:2, 3:4, 5:6, 7:8}
l = (1,5)
{key: d[key] for key in l}
In addition to Marty's excellent Answer, the SystemVerilog specification offers the byte
data type. The following declares a 4x8-bit variable (4 bytes), assigns each byte a value, then displays all values:
module tb;
byte b [4];
initial begin
foreach (b[i]) b[i] = 1 << i;
foreach (b[i]) $display("Address = %0d, Data = %b", i, b[i]);
$finish;
end
endmodule
This prints out:
Address = 0, Data = 00000001
Address = 1, Data = 00000010
Address = 2, Data = 00000100
Address = 3, Data = 00001000
This is similar in concept to Marty's reg [7:0] a [0:3];
. However, byte
is a 2-state data type (0 and 1), but reg
is 4-state (01xz). Using byte
also requires your tool chain (simulator, synthesizer, etc.) to support this SystemVerilog syntax. Note also the more compact foreach (b[i])
loop syntax.
The SystemVerilog specification supports a wide variety of multi-dimensional array types. The LRM can explain them better than I can; refer to IEEE Std 1800-2005, chapter 5.
This is another solution:
if os.path.isfile(os.path.join(path, filename)):
os.remove(os.path.join(path, filename))
Since someone mentioned efficiency, I've benchmarked the functions given so far out of curiosity:
function startsWith1($str, $char) {
return strpos($str, $char) === 0;
}
function startsWith2($str, $char) {
return stripos($str, $char) === 0;
}
function startsWith3($str, $char) {
return substr($str, 0, 1) === $char;
}
function startsWith4($str, $char){
return $str[0] === $char;
}
function startsWith5($str, $char){
return (bool) preg_match('/^' . $char . '/', $str);
}
function startsWith6($str, $char) {
if (is_null($encoding)) $encoding = mb_internal_encoding();
return mb_substr($str, 0, mb_strlen($char, $encoding), $encoding) === $char;
}
Here are the results on my average DualCore machine with 100.000 runs each

As you can see, treating the haystack as array to find out the char at the first position is always the fastest solution. It is also always performing at equal speed, regardless of string length. Using strpos
is faster than substr
for short strings but slower for long strings, when the string does not start with the prefix. The difference is irrelevant though. stripos
is incredibly slow with long strings. preg_match
performs mostly the same regardless of string length, but is only mediocre in speed. The mb_substr
solution performs worst, while probably being more reliable though.
Given that these numbers are for 100.000 runs, it should be obvious that we are talking about 0.0000x seconds per call. Picking one over the other for efficiency is a worthless micro-optimization, unless your app is doing startsWith
checking for a living.

Here is a C# version of the answer given by nirg, which comes from this RPI professor. Note that use of the code from that RPI source requires attribution.
A bounding box check has been added at the top. However, as James Brown points out, the main code is almost as fast as the bounding box check itself, so the bounding box check can actually slow the overall operation, in the case that most of the points you are checking are inside the bounding box. So you could leave the bounding box check out, or an alternative would be to precompute the bounding boxes of your polygons if they don't change shape too often.
public bool IsPointInPolygon( Point p, Point[] polygon )
{
double minX = polygon[ 0 ].X;
double maxX = polygon[ 0 ].X;
double minY = polygon[ 0 ].Y;
double maxY = polygon[ 0 ].Y;
for ( int i = 1 ; i < polygon.Length ; i++ )
{
Point q = polygon[ i ];
minX = Math.Min( q.X, minX );
maxX = Math.Max( q.X, maxX );
minY = Math.Min( q.Y, minY );
maxY = Math.Max( q.Y, maxY );
}
if ( p.X < minX || p.X > maxX || p.Y < minY || p.Y > maxY )
{
return false;
}
// https://wrf.ecse.rpi.edu/Research/Short_Notes/pnpoly.html
bool inside = false;
for ( int i = 0, j = polygon.Length - 1 ; i < polygon.Length ; j = i++ )
{
if ( ( polygon[ i ].Y > p.Y ) != ( polygon[ j ].Y > p.Y ) &&
p.X < ( polygon[ j ].X - polygon[ i ].X ) * ( p.Y - polygon[ i ].Y ) / ( polygon[ j ].Y - polygon[ i ].Y ) + polygon[ i ].X )
{
inside = !inside;
}
}
return inside;

Integer
refers to wrapper type in Java whereas int
is a primitive type. Everything except primitive data types in Java is implemented just as objects that implies Java is a highly qualified pure object-oriented programming language. If you need, all primitives types are also available as wrapper types in Java. You can have some performance benefit with primitive types, and hence wrapper types should be used only when it is necessary.
In your example as below.
Integer n = 9;
the constant 9
is being auto-boxed (auto-boxing
and unboxing
occurs automatically from java 5
onwards) to Integer
and therefore you can use the statement like that and also Integer n = new Integer(9)
. This is actually achieved through the statement Integer.valueOf(9).intValue();

Well According to a comment on the shuf answer he shuffed 78 000 000 000 lines in under a minute.
Challenge accepted...
EDIT: I beat my own record
$ time ./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null
./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null 0.02s user 0.01s system 80% cpu 0.047 total
The reason it is so fast, well I don't read the whole file and just move the file pointer 10 times and print the line after the pointer.
First I needed a file of 78.000.000.000 lines:
seq 1 78 | xargs -n 1 -P 16 -I% seq 1 1000 | xargs -n 1 -P 16 -I% echo "" > lines_78000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000.txt > lines_78000000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000000.txt > lines_78000000000.txt
This gives me a a file with 78 Billion newlines ;-)
Now for the shuf part:
$ time shuf -n 10 lines_78000000000.txt
shuf -n 10 lines_78000000000.txt 2171.20s user 22.17s system 99% cpu 36:35.80 total
The bottleneck was CPU and not using multiple threads, it pinned 1 core at 100% the other 15 were not used.
Python is what I regularly use so that's what I'll use to make this faster:
#!/bin/python3
import random
f = open("lines_78000000000.txt", "rt")
count = 0
while 1:
buffer = f.read(65536)
if not buffer: break
count += buffer.count('\n')
for i in range(10):
f.readline(random.randint(1, count))
This got me just under a minute:
$ time ./shuf.py
./shuf.py 42.57s user 16.19s system 98% cpu 59.752 total
I did this on a Lenovo X1 extreme 2nd gen with the i9 and Samsung NVMe which gives me plenty read and write speed.
I know it can get faster but I'll leave some room to give others a try.

With ES6: This is now part of the language:
function myFunc(a, b = 0) {
// function body
}
Please keep in mind that ES6 checks the values against undefined
and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).
With ES5:
function myFunc(a,b) {
b = b || 0;
// b will be set either to b or to 0.
}
This works as long as all values you explicitly pass in are truthy.
Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''
It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.
If you are on a mac you can install haxm
using homebrew via cask which is a built-in extension (as of 2015) which allows installing non-open-source and desktop apps (i.e. chrome, firefox, eclipse, etc.):
brew cask install intel-haxm
If you are using Android Studio then you can achieve the same result from the menu Tools ? SDK Manager, and then on the SDK Tools tab, select the checkbox for Intel x86 Emulator Accelerator (HAXM installer), and click Ok.

Maybe this could be useful:
def Retriever(bar):
return (list(globals().keys()))[list(map(lambda x: id(x), list(globals().values()))).index(id(bar))]
The function goes through the list of IDs of values from the global scope (the namespace could be edited), finds the index of the wanted/required var or function based on its ID, and then returns the name from the list of global names based on the acquired index.
There's a much simpler way to achieve this
.inner{color: red; text-shadow: 0 -1px 0 #666;} // #666 is the color of the inner shadow

If you are able to use NOW() this would be simplest form:
SELECT * FROM `fab_scheduler` WHERE eventdate>=(NOW() - INTERVAL 1 DAY)) AND eventdate<NOW() ORDER BY eventdate DESC;
With MySQL 5.6+ query abowe should do. Depending on sql server, You may be required to use CURRDATE()
instead of NOW()
- which is alias for DATE(NOW())
and will return only date part of datetime

for (i = 0, i < status.options.length, ++i) {
if (options[i].selected ) {
jsObj = { uniqueIDofSelect: status.id, optionValue: options[i].value };
break;
}
}
If you want an array of all such objects (not just the selected one), use michael's code but swap out status.options[i].text
for status.id
.
If you want a string that contains a JSON representation of the selected object, use this instead:
var jsonStr = "";
var status = document.getElementsByName("status")[0];
for (i = 0, i < status.options.length, ++i) {
if (options[i].selected ) {
jsonStr = '{ '
+ '"uniqueIDofSelect" : '
+ '"' + status.id + '"'
+ ", "
+ '"optionValue" : '
+ '"'+ options[i].value + '"'
+ ' }';
break;
}
}
The reason for this error is very simple. Your AJAX is trying to call over HTTP whereas your server is running over HTTPS, so your server is denying calling your AJAX. This can be fixed by adding the following line inside the head tag of your main HTML file:
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
The FOR loop worked well, I modified it a tiny bit:
#include<iostream>
using namespace std;
int main ()
{
int sum = 0;
int number;
int numberitems;
cout << "Enter number of items: \n";
cin >> numberitems;
for(int i=0;i<numberitems;i++)
{
cout << "Enter number: \n";
cin >> number;
sum=sum+number;
}
cout<<"sum is: "<< sum<<endl;
}
HOWEVER, the WHILE loop has got some errors on line 11 (Count was not declared in this scope). What could be the issue? Also, if you would have a solution using DO,WHILE loop it would be wonderful. Thanks
This does not work if you modify a pickled attribute of the model. Pickled attributes should be replaced in order to trigger updates:
from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy
from pprint import pprint
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqllite:////tmp/users.db'
db = SQLAlchemy(app)
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80), unique=True)
data = db.Column(db.PickleType())
def __init__(self, name, data):
self.name = name
self.data = data
def __repr__(self):
return '<User %r>' % self.username
db.create_all()
# Create a user.
bob = User('Bob', {})
db.session.add(bob)
db.session.commit()
# Retrieve the row by its name.
bob = User.query.filter_by(name='Bob').first()
pprint(bob.data) # {}
# Modifying data is ignored.
bob.data['foo'] = 123
db.session.commit()
bob = User.query.filter_by(name='Bob').first()
pprint(bob.data) # {}
# Replacing data is respected.
bob.data = {'bar': 321}
db.session.commit()
bob = User.query.filter_by(name='Bob').first()
pprint(bob.data) # {'bar': 321}
# Modifying data is ignored.
bob.data['moo'] = 789
db.session.commit()
bob = User.query.filter_by(name='Bob').first()
pprint(bob.data) # {'bar': 321}
I used this method to load a script file dynamically (inside a controller).
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "https://maps.googleapis.com/maps/api/js";
document.body.appendChild(script);
I found this helpful
<?php if (strpos($_SERVER['HTTP_USER_AGENT'], 'Trident/7.0; rv:11.0') !== false) { ?>
<script>
$(function(){
$('html').addClass('ie11');
});
</script>
<?php } ?>
Add this under your <head>
document
Try with padding
and line-height
-
input[type="text"]{ padding: 20px 10px; line-height: 28px; }
In English:
It's a
List
of some type that extends the classHasWord
, includingHasWord
In general the ?
in generics means any class. And the extends SomeClass
specifies that that object must extend SomeClass
(or be that class).
You're missing your database name:
$sql = "SELECT ID, ListStID, ListEmail, Title FROM ".$entry_database." WHERE ID = ". $ReqBookID .";
And make sure that $entry_database isn't null or empty:
var_dump($entry_database);
Also notice that you don't need to have $ReqBookID in '' as if it's an Int.
For those coming from Google (etc.) such as myself:
convert_objects
has been deprecated since 0.17 - if you use it, you get a warning like this one:
FutureWarning: convert_objects is deprecated. Use the data-type specific converters
pd.to_datetime, pd.to_timedelta and pd.to_numeric.
You should do something like the following:
df =
df.astype(np.float)
df["A"] =
pd.to_numeric(df["A"])
This worked for me:
curl -v --cookie "USER_TOKEN=Yes" http://127.0.0.1:5000/
I could see the value in backend using
print request.cookies
We had the same problem and this is the solution:
To force entity framework to use a column as a primary key, use ISNULL.
To force entity framework not to use a column as a primary key, use NULLIF.
An easy way to apply this is to wrap the select statement of your view in another select.
Example:
SELECT
ISNULL(MyPrimaryID,-999) MyPrimaryID,
NULLIF(AnotherProperty,'') AnotherProperty
FROM ( ... ) AS temp
minDate property for current date works on for both -> minDate:"yy-mm-dd" or minDate:0
To change status bar color use setStatusBarColor(int color). According the javadoc, we also need set some flags on the window.
Working snippet of code:
Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.setStatusBarColor(ContextCompat.getColor(activity, R.color.example_color));
Keep in mind according Material Design guidelines status bar color and action bar color should be different:
Look at the screenshot below:
.close-image {
cursor: pointer;
display: block;
float: right;
position: relative;
top: 22px;
z-index: 1;
}
I think this might be what you are looking for.
I find it very useful to append both stdout and stderr to a log file. I was glad to see a solution by alfonx with exec > >(tee -a)
, because I was wondering how to accomplish this using exec
. I came across a creative solution using here-doc syntax and .
: https://unix.stackexchange.com/questions/80707/how-to-output-text-to-both-screen-and-file-inside-a-shell-script
I discovered that in zsh, the here-doc solution can be modified using the "multios" construct to copy output to both stdout/stderr and the log file:
#!/bin/zsh
LOG=$0.log
# 8 is an arbitrary number;
# multiple redirects for the same file descriptor
# triggers "multios"
. 8<<\EOF /dev/fd/8 2>&2 >&1 2>>$LOG >>$LOG
# some commands
date >&2
set -x
echo hi
echo bye
EOF
echo not logged
It is not as readable as the exec
solution but it has the advantage of allowing you to log just part of the script. Of course, if you omit the EOF then the whole script is executed with logging. I'm not sure how zsh
implements multios, but it may have less overhead than tee
. Unfortunately it seems that one cannot use multios with exec
.
To store the third line into a variable, use below syntax:
variable=`echo "$1" | sed '3q;d' urfile`
To store the changed line into a variable, use below syntax:
variable=echo 'overflow' | sed -e "s/over/"OVER"/g"
output:OVERflow
Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this
String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");
and now you have a String which can be parsed back to java.lang.Number
, for example,
long veryLongNumber = Long.parseLong(intStr);
Or you can use the java 8 streams, if you hate regex,
String strOfInts = Arrays
.stream(intArray)
.mapToObj(String::valueOf)
.reduce((a, b) -> a.concat(",").concat(b))
.get();
You can use XDocument.Parse
for this.
With Docmosis or JODReports you could feed your HTML and Javascript to the document render process which could produce PDF or doc or other formats. The conversion underneath is performed by OpenOffice so results will be dependent on the OpenOffice import filters. You can try manually by saving your web page to a file, then loading with OpenOffice - if that looks good enough, then these tools will be able to give you the same result as a PDF.
I would like to add this, I used this in laravel to just index my table:
My Code:
@foreach($resultsPerCountry->first()->studies as $result)
<tr>
<td>{{ ++$loop->index}}</td>
</tr>
@endforeach
git add -u
git reset -- main/dontcheckmein.txt
You need to create a new Font
mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);
For me this was the solution.
The problem was that the SVN server was behind a reverse-proxy (pound). And the reverse proxy had to be told to allow OPTIONS

You can do this using Mockito to have the mock return the correct params, verify they were indeed called (optionally specify number of times), write the 'result' and verify it's correct.
import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import java.io.*;
import javax.servlet.http.*;
import org.apache.commons.io.FileUtils;
import org.junit.Test;
public class TestMyServlet extends Mockito{
@Test
public void testServlet() throws Exception {
HttpServletRequest request = mock(HttpServletRequest.class);
HttpServletResponse response = mock(HttpServletResponse.class);
when(request.getParameter("username")).thenReturn("me");
when(request.getParameter("password")).thenReturn("secret");
StringWriter stringWriter = new StringWriter();
PrintWriter writer = new PrintWriter(stringWriter);
when(response.getWriter()).thenReturn(writer);
new MyServlet().doPost(request, response);
verify(request, atLeast(1)).getParameter("username"); // only if you want to verify username was called...
writer.flush(); // it may not have been flushed yet...
assertTrue(stringWriter.toString().contains("My expected string"));
}
}
Just add the following rules to the parent element:
display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */
Here's a sample demo (Resize window to see the image align)
Browser support for Flexbox nowadays is quite good.
For cross-browser compatibility for display: flex
and align-items
, you can add the older flexbox syntax as well:
display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;
No matter what $action is, it will always either not be "add" OR not be "delete", which is why the if condition always passes. What you want is to use && instead of ||:
(!isset($action)) || ($action !="add" && $action !="delete"))
I think you want to open
the ZipFile, which returns a file-like object, rather than read
:
In [11]: crime2013 = pd.read_csv(z.open('crime_incidents_2013_CSV.csv'))
In [12]: crime2013
Out[12]:
<class 'pandas.core.frame.DataFrame'>

The most upVoted answer seems working but become hectic for developers to see their minor changes after couple of minutes. I solved this issue by following these steps: 1- Push my code to bitbucket/github repo ( to view the changes later ) 2- cut paste android folder to any safe location for recovery 3- delete the android folder from my project 4- run react-native upgrade 5- Now, I see all the changes between the previous and the lastest build (using VsCode) 6- I found the issue in build.gradle file in these lines of code.
ext {
buildToolsVersion = "28.0.2"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 27
supportLibVersion = "28.0.0"
}
7- I copied these lines ( generated by react-native upgrade script and delete the android folder again. 8- Then I cut paste android folder back in my project folder which I Cut Pasted in step 2. 9 - Replace build.gradle files lines with the copied ones. 10- Now It works as normal.
Hope this will help you.
I use WinForms and my way to use File.Exists(string path) is the next one:
public bool FileExists(string fileName)
{
var workingDirectory = Environment.CurrentDirectory;
var file = $"{workingDirectory}\{fileName}";
return File.Exists(file);
}
fileName must include the extension like myfile.txt
I think there's an even easier way now. This enables basic caching for all $http requests (which $resource inherits):
var app = angular.module('myApp',[])
.config(['$httpProvider', function ($httpProvider) {
// enable http caching
$httpProvider.defaults.cache = true;
}])
Though they operate the same way, however, the mouseenter
event only triggers when the mouse pointer enters the selected element. The mouseover
event is triggered if a mouse pointer enters any child elements as well.
Attach
ing an entity will set its tracking state to Unchanged
. To update an existing entity, all you need to do is set the tracking state to Modified
. According to the EF6 docs:
If you have an entity that you know already exists in the database but to which changes may have been made then you can tell the context to attach the entity and set its state to Modified. For example:
var existingBlog = new Blog { BlogId = 1, Name = "ADO.NET Blog" }; using (var context = new BloggingContext()) { context.Entry(existingBlog).State = EntityState.Modified; // Do some more work... context.SaveChanges(); }
For macOS I use two commands together to show information about the processes listening on the machine and process connecting to remote servers. In other words, to check the listening ports and the current (TCP) connections on a host you could use the two following commands together
1. netstat -p tcp -p udp
2. lsof -n -i4TCP -i4UDP
Thought I would add my input, hopefully it can end up helping someone.
Let's imagine that you want to go fishing:
Without dependency injection, you need to take care of everything yourself. You need to find a boat, to buy a fishing rod, to look for bait, etc. It's possible, of course, but it puts a lot of responsibility on you. In software terms, it means that you have to perform a lookup for all these things.
With dependency injection, someone else takes care of all the preparation and makes the required equipment available to you. You will receive ("be injected") the boat, the fishing rod and the bait - all ready to use.
Try this:
-- http://lua-users.org/wiki/FileInputOutput
-- see if the file exists
function file_exists(file)
local f = io.open(file, "rb")
if f then f:close() end
return f ~= nil
end
-- get all lines from a file, returns an empty
-- list/table if the file does not exist
function lines_from(file)
if not file_exists(file) then return {} end
lines = {}
for line in io.lines(file) do
lines[#lines + 1] = line
end
return lines
end
-- tests the functions above
local file = 'test.lua'
local lines = lines_from(file)
-- print all line numbers and their contents
for k,v in pairs(lines) do
print('line[' .. k .. ']', v)
end
It's currently working, I've just changed the operator >
in order to work in the snippet, take a look:
window.onload = function() {_x000D_
_x000D_
if (window.location.href.indexOf("test") <= -1) {_x000D_
var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
search_span[0].style.color = "blue";_x000D_
search_span[0].style.fontWeight = "bold";_x000D_

You cannot add default values for function parameters. But you can do this:
function tester(paramA, paramB){
if (typeof paramA == "undefined"){
paramA = defaultValue;
}
if (typeof paramB == "undefined"){
paramB = defaultValue;
}
}
In contrast to Matt J his answer, I use a simple object. This gives me the possibily to parse this handler to all the threads that needs to be stopped securlery.
class SIGINT_handler():
def __init__(self):
self.SIGINT = False
def signal_handler(self, signal, frame):
print('You pressed Ctrl+C!')
self.SIGINT = True
handler = SIGINT_handler()
signal.signal(signal.SIGINT, handler.signal_handler)
Elsewhere
while True:
# task
if handler.SIGINT:
break
This is an error of type database trigger policies. A trigger is code and can add some intelligences or conditions to a Cascade relation like Cascade Deletion. You may need to specialize the related tables options around this like Turning off CascadeOnDelete:
protected override void OnModelCreating( DbModelBuilder modelBuilder )
{
modelBuilder.Entity<TableName>().HasMany(i => i.Member).WithRequired().WillCascadeOnDelete(false);
}
Or Turn off this feature completely:
modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
Can a constructor be private? How is a private constructor useful?
Yes it can. I consider this another example of it being useful:
//... ErrorType.java
public enum ErrorType {
X,
Y,
Z
}
//... ErrorTypeException.java
import java.util.*;
import java.lang.*;
import java.io.*;
//Translates ErrorTypes only
abstract public class ErrorTypeException extends Exception {
private ErrorTypeException(){}
//I don't want to expose thse
static private class Xx extends ErrorTypeException {}
static private class Yx extends ErrorTypeException {}
static private class Zx extends ErrorTypeException {}
// Want translation without exposing underlying type
public static Exception from(ErrorType errorType) {
switch (errorType) {
case X:
return new Xx();
case Y:
return new Yx();
default:
return new Zx();
}
}
// Want to get hold of class without exposing underlying type
public static Class<? extends ErrorTypeException> toExceptionClass(ErrorType errorType) {
switch (errorType) {
case X:
return Xx.class;
case Y:
return Yx.class;
default:
return Zx.class;
}
}
}
In the case here above, it prevents the abstract class from being instantiated by any derived class other than it's static inner classes. Abstract classes cannot be final, but in this case the private constructor makes it effectively final to all classes that aren't inner classes
run-sequence is the most clear way (at least until Gulp 4.0 is released)
With run-sequence, your task will look like this:
var sequence = require('run-sequence');
/* ... */
gulp.task('develop', function (done) {
sequence('clean', 'coffee', done);
});
But if you (for some reason) prefer not using it, gulp.start
method will help:
gulp.task('develop', ['clean'], function (done) {
gulp.on('task_stop', function (event) {
if (event.task === 'coffee') {
done();
}
});
gulp.start('coffee');
});
Note: If you only start task without listening to result, develop
task will finish earlier than coffee
, and that may be confusing.
You may also remove event listener when not needed
gulp.task('develop', ['clean'], function (done) {
function onFinish(event) {
if (event.task === 'coffee') {
gulp.removeListener('task_stop', onFinish);
done();
}
}
gulp.on('task_stop', onFinish);
gulp.start('coffee');
});
Consider there is also task_err
event you may want to listen to.
task_stop
is triggered on successful finish, while task_err
appears when there is some error.
You may also wonder why there is no official documentation for gulp.start()
. This answer from gulp member explains the things:
gulp.start
is undocumented on purpose because it can lead to complicated build files and we don't want people using it
(source: https://github.com/gulpjs/gulp/issues/426#issuecomment-41208007)
There is no REVOKE ALL PRIVILEGES ON ALL VIEWS
, so I ended with:
do $$
DECLARE r record;
begin
for r in select * from pg_views where schemaname = 'myschem'
loop
execute 'revoke all on ' || quote_ident(r.schemaname) ||'.'|| quote_ident(r.viewname) || ' from "XUSER"';
end loop;
end $$;
and usual:
REVOKE ALL PRIVILEGES ON DATABASE mydb FROM "XUSER";
REVOKE ALL PRIVILEGES ON SCHEMA myschem FROM "XUSER";
REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA myschem FROM "XUSER";
REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA myschem FROM "XUSER";
REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA myschem FROM "XUSER";
for the following to succeed:
drop role "XUSER";

Since Git 2.5.0 this configuration variable can be enabled on the server, here the GitHub feature request and the GitHub commit enabling this feature.
Bitbucket Server enabled it since version 5.5+.
Usage:
# Make remote with 4 commits, and local with just one.
mkdir server
cd server
git init
touch 1
git add 1
git commit -m 1
git clone ./ ../local
for i in {2..4}; do
touch "$i"
git add "$i"
git commit -m "$i"
done
# Before last commit.
SHA3="$(git log --format='%H' --skip=1 -n1)"
# Last commit.
SHA4="$(git log --format='%H' -n1)"
# Failing control without feature.
cd ../local
# Does not give an error, but does not fetch either.
git fetch origin "$SHA3"
# Error.
git checkout "$SHA3"
# Enable the feature.
cd ../server
git config uploadpack.allowReachableSHA1InWant true
# Now it works.
cd ../local
git fetch origin "$SHA3"
git checkout "$SHA3"
# Error.
git checkout "$SHA4"
Are you looking at something like this, below is tested in SQL Server 2005
SELECT * FROM sys.check_constraints WHERE
object_id = OBJECT_ID(N'[dbo].[CK_accounts]') AND
parent_object_id = OBJECT_ID(N'[dbo]. [accounts]')
I think you maybe want ts_create as datetime (so rename -> dt_create) and only ts_update as timestamp? This will ensure it remains unchanging once set.
My understanding is that datetime is for manually-controlled values, and timestamp's a bit "special" in that MySQL will maintain it for you. In this case, datetime is therefore a good choice for ts_create.
If you want absolute urls, you have the third parameter.
$product_url = $this->generateUrl('product_detail',
array(
'slug' => 'slug'
),
UrlGeneratorInterface::ABSOLUTE_URL
);
Remember to include UrlGeneratorInterface.
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
This has been driving me crazy for literally weeks. I found a solution that will work for me that includes:
...but there are a couple of caveats:
The vertical scrollbar is not visible until you scroll all the way to the right. Given that most people have scroll wheels, this was an acceptable sacrifice.
The width of the scrollbar must be known. On my website I set the scrollbar widths (I'm not overly concerned with older, incompatible browsers), so I can then calculate div
and table
widths that adjust based on the scrollbar.
Instead of posting my code here, I'll post a link to the jsFiddle.
