It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:
[...] when looping through the
Iterable
value list, each Object instance is re-used, so it only keeps one instance around at a given time.
If you know how far back, you can try something like:
# Current branch vs. parent
git diff HEAD^ HEAD
# Current branch, diff between commits 2 and 3 times back
git diff HEAD~3 HEAD~2
Prior commits work something like this:
# Parent of HEAD
git show HEAD^1
# Grandparent
git show HEAD^2
There are a lot of ways you can specify commits:
# Great grandparent
git show HEAD~3
In my view, With Expire Header, server can tell the client when my data would be stale, while with Etag, server would check the etag value for client' each request.
After struggling a bit with some of the answers here, I found a library called backoff that worked better for my situation. A basic example:
import backoff
@backoff.on_exception(
backoff.expo,
requests.exceptions.RequestException,
max_tries=5,
giveup=lambda e: e.response is not None and e.response.status_code < 500
)
def publish(self, data):
r = requests.post(url, timeout=10, json=data)
r.raise_for_status()
I'd still recommend giving the library's native functionality a shot, but if you run into any problems or need broader control, backoff is an option.
Look at this: http://phpjs.org/functions/index and find for print_r or use console.log() with firebug.
Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.
The query with the LIKE
keyword showed a clustered index scan.
The CONTAINS
also had a clustered index scan with additional operators for the full text match and a merge join.
I got a solution after a long time in tutorials.
I followed the github tutorial on this link -> https://help.github.com/articles/error-permission-denied-publickey and I was able to connect in every step. But when I was trying to git push -u origin master I got this error:
Permission denied (publickey). fatal: Could not read from remote repository.
Please make sure you have the correct access rights
Thats how I`ve fixed it!! Go to the project directory using the Terminal and check it out
$git remote -v
You will get something like this:
origin ssh://[email protected]/yourGithubUserName/yourRepo.git (fetch)
origin ssh://[email protected]/yourGithubUserName/yourRepo.git (push)
If you are using anything different then [email protected], open the config file on git directory by typing the command:
vi .git/config
And configure the line
[remote "origin"]
url = ssh://[email protected]/yourGithubUserName/yourRepo.git
fetch = +refs/heads/*:refs/remotes/origin/
First, implement the MyData.equals(Object o)
and MyData.hashCode()
methods.
Once you implemented the equals
method, you can iterate over the lists as follows:
if(ListA == null && ListB == null)
return false;
if(ListA == null && ListB != null)
return true;
if(ListA != null && ListB == null)
return true;
int max = ListA.size() > ListB.size() ? ListA.size() : ListB.size();
for(int i = 0; i < max; i++) {
myData1 = ListA.get(i);
myData2 = ListB.get(i);
if(!myData1.equals(myData2)) {
return true;
}
}
return false;
I will use CXF also you can think of AXIS 2 .
The best way to do it may be using JAX RS Refer this example
Example:
wsimport -p stockquote http://stockquote.xyz/quote?wsdl
This will generate the Java artifacts and compile them by importing the http://stockquote.xyz/quote?wsdl.
I
Java's Double
class has members containing the Min and Max value for the type.
2^-1074 <= x <= (2-2^-52)·2^1023 // where x is the double.
Check out the Min_VALUE
and MAX_VALUE
static final members of Double
.
(some)People will suggest against using floating point types for things where accuracy and precision are critical because rounding errors can throw off calculations by measurable (small) amounts.
TRUNCATE can be rolled back if wrapped in a transaction.
Please see the two references below and test yourself:-
The TRUNCATE vs. DELETE is one of the infamous questions during SQL interviews. Just make sure you explain it properly to the Interviewer or it might cost you the job. The problem is that not many are aware so most likely they will consider the answer as wrong if you tell them that YES Truncate can be rolled back.
Extention for prior Java 8 solution
String result = String.join(",", name);
If you need prefix or/ and suffix for array values
StringJoiner joiner = new StringJoiner(",");
for (CharSequence cs: name) {
joiner.add("'" + cs + "'");
}
return joiner.toString();
Or simple method concept
public static String genInValues(String delimiter, String prefix, String suffix, String[] name) {
StringJoiner joiner = new StringJoiner(delimiter);
for (CharSequence cs: name) {
joiner.add(prefix + cs + suffix);
}
return joiner.toString();
}
For example
For Oracle i need "id in (1,2,3,4,5)"
then use genInValues(",", "", "", name);
But for Postgres i need "id in (values (1),(2),(3),(4),(5))"
then use genInValues(",", "(", ")", name);

I've been searching high and low for an end-to-end example of a complete maven-based ear-packaged application and finally stumbled upon this. The instructions say to select option 2 when running through the CLI but for your purposes, use option 1.

I noticed some caching issues with service calls when repeating the same service call (long polling). Adding metadata didn't help. One solution is to pass a timestamp
to ensure ie
thinks it's a different http
service request. That worked for me, so adding a server side scripting code snippet to automatically update this tag wouldn't hurt:
<meta http-equiv="expires" content="timestamp">
1. git remote add origin [email protected]:User/UserRepo.git
git init
.origin
is an alias/alternate name for your remote repository so that you don't have to type the entire path for remote every time and henceforth you are declaring that you will use this name(origin) to refer to your remote. This name could be anything.git remote -v
OR git remote get-url origin
2. git remote set-url origin [email protected]:User/UserRepo.git
This command means that if at any stage you wish to change the location of your repository(i.e if you made a mistake while adding the remote path using the git add
command) the first time, you can easily go back & "reset(update) your current remote repository path" by using the above command.
3. git push -u remote master
This command simply pushes your files to the remote repository.Git has a concept of something known as a "branch", so by default everything is pushed to the master branch unless explicitly specified an alternate branch.
To know about the list of all branches you have in your repository type :git branch
Without knowing more about the problem domain, it's hard to answer your question. Unless you are certain that you need to do something more, the pythonic way to initialize a list is:
verts = []
Are you actually seeing a performance problem? If so, what is the performance bottleneck? Don't try to solve a problem that you don't have. It's likely that performance cost to dynamically fill an array to 1000 elements is completely irrelevant to the program that you're really trying to write.
The array class is useful if the things in your list are always going to be a specific primitive fixed-length type (e.g. char, int, float). But, it doesn't require pre-initialization either.
As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined
keyword.
tasks:
- shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
when: foo is defined
- fail: msg="Bailing out. this play requires 'bar'"
when: bar is undefined
In HTML, SGML and XML, (1) attributes cannot be repeated, and should only be defined in an element once.
So your example:
<span style="color:blue" style="font-style:italic">Test</span>
is non-conformant to the HTML standard, and will result in undefined behaviour, which explains why different browsers are rendering it differently.
Since there is no defined way to interpret this, browsers can interpret it however they want and merge them, or ignore them as they wish.
(1): Every article I can find states that attributes are "key/value" pairs or "attribute-value" pairs, heavily implying the keys must be unique. The best source I can find states:
Attribute names (id and status in this example) are subject to the same restrictions as other names in XML; they need not be unique across the whole DTD, however, but only within the list of attributes for a given element. (Emphasis mine.)
The python error says that wordInput
is not an iterable -> it is of NoneType.
If you print wordInput
before the offending line, you will see that wordInput
is None
.
Since wordInput
is None
, that means that the argument passed to the function is also None
. In this case word
. You assign the result of pickEasy
to word
.
The problem is that your pickEasy
function does not return anything. In Python, a method that didn't return anything returns a NoneType.
I think you wanted to return a word
, so this will suffice:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
Note: This is not a duplicate, because the OP is aware that the image from cv2.imread
is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)
To illustrate, I've opened up this same color JPEG image:
once using the conversion
img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
and another by loading it in gray scale mode
img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)
Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom
I've summed up the diff too to see
import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image
I tried all cv2.imread()
modes
Among all the IMREAD_
modes for cv2.imread()
, only IMREAD_COLOR
and IMREAD_ANYCOLOR
can be converted using COLOR_BGR2GRAY
, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE
The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)
Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.
In brief, let's not mix the versions and types in the processing pipeline.
So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Here is how to implement this for the PowerShell folks
$IncommingPath = "F:\WebContent"
$Acl = Get-Acl $IncommingPath
$Ar = New-Object system.security.accesscontrol.filesystemaccessrule("IIS AppPool\DefaultAppPool","FullControl","ContainerInherit, ObjectInherit", "None", "Allow")
$Acl.SetAccessRule($Ar)
Set-Acl $IncommingPath $Acl
If you don't want anything to display before the redirect, then you will need to use some server side scripting to accomplish the task before the page is served. The page has already begun loading by the time your Javascript is executed on the client side.
If Javascript is your only option, your best best is to make your script the first .js file included in the <head>
of your document.
Instead of Javascript, I recommend setting up your redirect logic in your Apache or nginx server configuration.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageButton android:id="@+id/btnFindMe"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity = "center"
android:background="@drawable/findme">
</ImageButton>
</LinearLayout>
The above code will work.
In Angular 10, this is what works for me: In the HTML:
<mat-table [dataSource]="myArray">
In the component TS:
myArray: MyObject[] = [];
addObjectToTable(object:MyObject): void {
//TO PREVENT DUPLICATED OBJECTS
if (object&& !this.myArray.includes(object)) {
this.myArray.push(object);
// TO FORCE DATA-TABLE's DATASOURCE TO REFRESH
this.myArray= [...this.myArray];
}
}
A note - when using ExtendScript JavaScript (the Adobe Scripting language used in applications like Photoshop CS3+), the character to use is "\r". "\n" will be interpreted as a font character, and many fonts will thus have a block character instead.
For example (to select a layer named 'Note' and add line feeds after all periods):
var layerText = app.activeDocument.artLayers.getByName('Note').textItem.contents;
layerText = layerText.replace(/\. /g,".\r");
Since you're using JPA, use the Lob
annotation (and optionally the Column
annotation). Here is what the JPA specification says about it:
9.1.19 Lob Annotation
A
Lob
annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use theLob
annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with theBasic
annotation. A Lob may be either a binary or character type. The Lob type is inferred from the type of the persistent field or property, and except for string and character-based types defaults to Blob.
So declare something like this:
@Lob
@Column(name="CONTENT", length=512)
private String content;
Here is some LESS for you, in case you customize the navbar:
.navbar .divider-vertical {
height: floor(@navbar-height - @navbar-margin-bottom);
margin: floor(@navbar-margin-bottom / 2) 9px;
border-left: 1px solid #f2f2f2;
border-right: 1px solid #ffffff;
}
Here's how you convert numbers to strings, and join strings to other things (it's weird):
>> ['the number is ' num2str(15) '.']
ans =
the number is 15.
Select 'Other Users' from the and select your user(schema), under which you will be able to see your tables and views.
Here's the mysql reference for cursors. So I'm guessing it's something like this:
DECLARE done INT DEFAULT 0;
DECLARE products_id INT;
DECLARE result varchar(4000);
DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
OPEN cur1;
REPEAT
FETCH cur1 INTO products_id;
IF NOT done THEN
CALL generate_parameter_list(@product_id, @result);
SET param = param + "," + result; -- not sure on this syntax
END IF;
UNTIL done END REPEAT;
CLOSE cur1;
-- now trim off the trailing , if desired
This just means that the git clone copied the files down from github and placed them into a folder. If you try to do it again it will not let you because it can't clone into a folder that has files into it. So if you think the git clone did not complete properly, just delete the folder and do the git clone again. The clone creates a folder the same name as the git repo.
For laravel 5 and onwards using only DB::getQueryLog() , will not do. BY default in this the value of
protected $loggingQueries = false;
change it to
protected $loggingQueries = true;
in the below file for logging query.
/vendor/laravel/framework/src/illuminate/Database/Connection.php
And then we can use the DB::getQueryLog()
where you want to print the query.
Create a new Java project in Eclipse. This will create a src folder (to contain your source files).
Also create a lib folder (the name isn't that important, but it follows standard conventions).
Copy the ./com/*
folders into the /src
folder (you can just do this using the OS, no need to do any fancy importing or anything from the Eclipse GUI).
Copy any dependencies (jar
files that your project itself depends on) into /lib
(note that this should NOT include the TGGL jar
- thanks to commenter Mike Deck for pointing out my misinterpretation of the OPs post!)
Copy the other TGGL stuff into the root project folder (or some other folder dedicated to licenses that you need to distribute in your final app)
Back in Eclipse, select the project you created in step 1, then hit the F5 key (this refreshes Eclipse's view of the folder tree with the actual contents.
The content of the /src
folder will get compiled automatically (with class files placed in the /bin file that Eclipse generated for you when you created the project). If you have dependencies (which you don't in your current project, but I'll include this here for completeness), the compile will fail initially because you are missing the dependency jar files
from the project classpath.
Finally, open the /lib
folder in Eclipse, right click
on each required jar file
and choose Build Path->Add
to build path.
That will add that particular jar to the classpath for the project. Eclipse will detect the change and automatically compile the classes that failed earlier, and you should now have an Eclipse project with your app in it.

Just in case this helps anyone that may have made the same mistake I did.
My website has a SSL certificate by Certify the Web.
When I published, I deleted the _Well-Known folder and this error came up.
Had I not emptied my recycle bin 30 seconds before I figured this out on my virtual machine, I could have just restored the folder.
Instead, I re-requested my certificate, restarted that site and the issue was resolved.
Since CKEditor v4.1, you can do this in config.js of CKEditor:
CKEDITOR.editorConfig = function( config ) {
config.extraAllowedContent = '*[id](*)'; // remove '[id]', if you don't want IDs for HTML tags
}
You can refer to the official documentation for the detailed syntax of Allowed Content Rules

I was trying to do the exact same thing, open a text file (a CSV for Pandas actually). Don't want to make a copy of it, just want to open it. The form-WTF has a nice file browser, but then it opens the file and makes a temporary file, which it presents as a memory stream. With a little work under the hood,
form = UploadForm()
if form.validate_on_submit():
filename = secure_filename(form.fileContents.data.filename)
filestream = form.fileContents.data
filestream.seek(0)
ef = pd.read_csv( filestream )
sr = pd.DataFrame(ef)
return render_template('dataframe.html',tables=[sr.to_html(justify='center, classes='table table-bordered table-hover')],titles = [filename], form=form)
Just to add a couple of points:
Because the Validate()
method signature returns IEnumerable<>
, that yield return
can be used to lazily generate the results - this is beneficial if some of the validation checks are IO or CPU intensive.
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
if (this.Enable)
{
// ...
if (this.Prop1 > this.Prop2)
{
yield return new ValidationResult("Prop1 must be larger than Prop2");
}
Also, if you are using MVC ModelState
, you can convert the validation result failures to ModelState
entries as follows (this might be useful if you are doing the validation in a custom model binder):
var resultsGroupedByMembers = validationResults
.SelectMany(vr => vr.MemberNames
.Select(mn => new { MemberName = mn ?? "",
Error = vr.ErrorMessage }))
.GroupBy(x => x.MemberName);
foreach (var member in resultsGroupedByMembers)
{
ModelState.AddModelError(
member.Key,
string.Join(". ", member.Select(m => m.Error)));
}
Corrected a few things and added an alternative select - delete as appropriate.

I tried the first answer: git stash
with the highest score but the error message still popped up, and then I found this article to commit the changes instead of stash 'Reluctant Commit'
and the error message disappeared finally:
1: git add .
2: git commit -m "this is an additional commit"
3: git checkout the-other-file-name
then it worked. hope this answer helps.:)
'' encloses single char
, while "" encloses a String

Create the index.blade.php file in the views folder, that should be all
You have a few options:
Using Enumerable.Where:
list.Where(i => i.Property == value).FirstOrDefault(); // C# 3.0+
Using List.Find:
list.Find(i => i.Property == value); // C# 3.0+
list.Find(delegate(Item i) { return i.Property == value; }); // C# 2.0+
Both of these options return default(T)
(null
for reference types) if no match is found.
As mentioned in the comments below, you should use the appropriate form of comparison for your scenario:
==
for simple value types or where use of operator overloads are desiredobject.Equals(a,b)
for most scenarios where the type is unknown or comparison has potentially been overriddenstring.Equals(a,b,StringComparison)
for comparing stringsobject.ReferenceEquals(a,b)
for identity comparisons, which are usually the fastestTwo simple examples to capture output the pwd
command:
$ b=$(pwd)
$ echo $b
/home/user1
or
$ a=`pwd`
$ echo $a
/home/user1
The first way is preferred. Note that there can't be any spaces after the =
for this to work.
Example using a short script:
#!/bin/bash
echo "hi there"
then:
$ ./so.sh
hi there
$ a=$(so.sh)
$ echo $a
hi there
In general a more flexible approach would be to return an exit value from the command and use it for further processing, though sometimes we just may want to capture the simple output from a command.
If you want to add a scroll bar using jquery the following will work. If your div had a id of 'mydiv' you could us the following jquery id selector with css property:
jQuery('#mydiv').css("overflow-y", "scroll");
Set return type to Void
instead of void
and return null
// Modify existing method
public static Void displayInt(Integer i) {
System.out.println(i);

dynamic_cast
is known to be inefficient. It traverses up the inheritance hierarchy, and it is the only solution if you have multiple levels of inheritance, and need to check if an object is an instance of any one of the types in its type hierarchy.
But if a more limited form of instanceof
that only checks if an object is exactly the type you specify, suffices for your needs, the function below would be a lot more efficient:
template<typename T, typename K>
inline bool isType(const K &k) {
return typeid(T).hash_code() == typeid(k).hash_code();
}
Here's an example of how you'd invoke the function above:
DerivedA k;
Base *p = &k;
cout << boolalpha << isType<DerivedA>(*p) << endl; // true
cout << boolalpha << isType<DerivedB>(*p) << endl; // false
You'd specify template type A
(as the type you're checking for), and pass in the object you want to test as the argument (from which template type K
would be inferred).
In my case neither M
or G
helped, so I have converted allocated memory to bytes using: https://www.gbmb.org/mb-to-bytes
4096M = 4294967296
php.ini:
memory_limit = 4294967296
Since you're dealing with values that are just supposed to be boolean anyway, just use ==
and convert the logical response to as.integer
:
df <- data.frame(col = c("true", "true", "false"))
df
# col
# 1 true
# 2 true
# 3 false
df$col <- as.integer(df$col == "true")
df
# col
# 1 1
# 2 1
# 3 0
The best thing is probably to create a variable that holds your binaries:
binaries=code1 code2
Then use that in the all
-target, to avoid repeating:
all: clean $(binaries)
Now, you can use this with the clean
-target, too, and just add some globs to catch object files and stuff:
.PHONY: clean
clean:
rm -f $(binaries) *.o
Note use of the .PHONY
to make clean
a pseudo-target. This is a GNU make feature, so if you need to be portable to other make implementations, don't use it.
The simplest solution (without depending on any third-party library or platform) is to create a URL instance pointing to the web page / link you want to download, and read the content using streams.
For example:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class DownloadPage {
public static void main(String[] args) throws IOException {
// Make a URL to the web page
URL url = new URL("http://stackoverflow.com/questions/6159118/using-java-to-pull-data-from-a-webpage");
// Get the input stream through URL Connection
URLConnection con = url.openConnection();
InputStream is =con.getInputStream();
// Once you have the Input Stream, it's just plain old Java IO stuff.
// For this case, since you are interested in getting plain-text web page
// I'll use a reader and output the text content to System.out.
// For binary content, it's better to directly read the bytes from stream and write
// to the target file.
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line = null;
// read each line and write to System.out
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
Hope this helps.
It IS possible, using something like the below example that I put together with the help of work from (https://gist.github.com/bitinn/1700068a276fb29740a7) that didn't quite work on iOS 11:

If you would like to stay in spring boot space just set the pom packaging to jar
<packaging>jar</packaging>
and add the spring-boot-maven-plugin to you build properties in the pom.xml file:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
then a simple mvn package command will create a complete executable jar file.

fit()
method mentioned by @Saullo Castro provides maximum likelihood estimates (MLE). The best distribution for your data is the one give you the highest can be determined by several different ways: such as
1, the one that gives you the highest log likelihood.
2, the one that gives you the smallest AIC, BIC or BICc values (see wiki: http://en.wikipedia.org/wiki/Akaike_information_criterion, basically can be viewed as log likelihood adjusted for number of parameters, as distribution with more parameters are expected to fit better)
3, the one that maximize the Bayesian posterior probability. (see wiki: http://en.wikipedia.org/wiki/Posterior_probability)
Of course, if you already have a distribution that should describe you data (based on the theories in your particular field) and want to stick to that, you will skip the step of identifying the best fit distribution.
scipy
does not come with a function to calculate log likelihood (although MLE method is provided), but hard code one is easy: see Is the build-in probability density functions of `scipy.stat.distributions` slower than a user provided one?

<script>
function getSummary(id)
{
$.ajax({
type: "GET",
url: 'Your URL',
data: "id=" + id, // appears as $_GET['id'] @ your backend side
success: function(data) {
// data is ur summary
$('#summary').html(data);
}
});
}
</script>
And add onclick
event in your lists
<a onclick="getSummary('1')">View Text</a>
<div id="#summary">This text will be replaced when the onclick event (link is clicked) is triggered.</div>
I believe you can do this:
gem "foo", path: "/path/to/foo"
If you select the input by the id and then add the input[readonly="readonly"]
tag in the css, something like:
#inputID input[readonly="readonly"] {
background-color: #000000;
}
That will not work. You have to select a parent class or id an then the input. Something like:
.parentClass, #parentID input[readonly="readonly"] {
background-color: #000000;
}
My 2 cents while waiting for new tickets at work :D
/**
* @Route("/category/{id}", name="_category")
* @Route("/category/{id}/{active}", name="_be_activatecategory")

May works.
Use this:

, but it didn't work.
Requires PHP 5.3 to work ("first day of" is introduced in PHP 5.3). Otherwise the example above is the only way to do it:
<?php
// First day of this month
$d = new DateTime('first day of this month');
echo $d->format('jS, F Y');
// First day of a specific month
$d = new DateTime('2010-01-19');
$d->modify('first day of this month');
echo $d->format('jS, F Y');
// alternatively...
echo date_create('2010-01-19')
->modify('first day of this month')
->format('jS, F Y');
In PHP 5.4+ you can do this:
<?php
// First day of this month
echo (new DateTime('first day of this month'))->format('jS, F Y');
echo (new DateTime('2010-01-19'))
->modify('first day of this month')
->format('jS, F Y');
If you prefer a concise way to do this, and already have the year and month in numerical values, you can use date()
:
<?php
echo date('Y-m-01'); // first day of this month
echo date("$year-$month-01"); // first day of a month chosen by you
Two possible approaches.
If you have a foreign key, declare it as on-delete-cascade and delete the parent rows older than 30 days. All the child rows will be deleted automatically.
Based on your description, it looks like you know the parent rows that you want to delete and need to delete the corresponding child rows. Have you tried SQL like this?
delete from child_table
where parent_id in (
select parent_id from parent_table
where updd_tms != (sysdate-30)
-- now delete the parent table records
delete from parent_table
where updd_tms != (sysdate-30);
---- Based on your requirement, it looks like you might have to use PL/SQL. I'll see if someone can post a pure SQL solution to this (in which case that would definitely be the way to go).
declare
v_sqlcode number;
PRAGMA EXCEPTION_INIT(foreign_key_violated, -02291);
begin
for v_rec in (select parent_id, child id from child_table
where updd_tms != (sysdate-30) ) loop
-- delete the children
delete from child_table where child_id = v_rec.child_id;
-- delete the parent. If we get foreign key violation,
-- stop this step and continue the loop
begin
delete from parent_table
where parent_id = v_rec.parent_id;
exception
when foreign_key_violated
then null;
end;
end loop;
end;

you can think of the if
and else
as a pair, that satisfies two actions
for one given condition
.
ex: if
it rains, take an umbrella else
go without an umbrella.
there are two actions
and both the two actions are bound to one condition, i.e
is it raining?
now, consider a scenario where there are multiple conditions and actions, bound together.
ex: if
you are hungry and
you are not broke, enjoy your meal at kfc, else if
you are hungry but
you are broke, try to compromise, else if
you are not hungry, but you just want to hangout in a cafe, try startbucks, else
do anything, just don't ask me about hunger or food. i have got bigger things to worry.
the else if
statement to to string together all the actions that falls in between the if
and the else
conditions.
The appropriate regex would be the ' char followed by any number of any chars [including zero chars] ending with an end of string/line token:
'.*$
And if you wanted to capture everything after the ' char but not include it in the output, you would use:
(?<=').*$
This basically says give me all characters that follow the ' char until the end of the line.
Edit: It has been noted that $ is implicit when using .* and therefore not strictly required, therefore the pattern:
'.*
is technically correct, however it is clearer to be specific and avoid confusion for later code maintenance, hence my use of the $. It is my belief that it is always better to declare explicit behaviour than rely on implicit behaviour in situations where clarity could be questioned.
I believe you want to use confirm()
<script type="text/javascript">
function clicked() {
if (confirm('Do you want to submit?')) {
yourformelement.submit();
} else {
return false;
}
}
</script>
As mentioned by few users, below code can help find all the fields in a given class.
TestClass testObject= new TestClass().getClass();
Method[] methods = testObject.getMethods();
for (Method method:methods)
{
String name=method.getName();
if(name.startsWith("get"))
{
System.out.println(name.substring(3));
}else if(name.startsWith("is"))
{
System.out.println(name.substring(2));
}
}
However a more interesting approach is below:
With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)
TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();
Map<String,Object> props = m.convertValue(testObject, Map.class);
for(Map.Entry<String, Object> entry : props.entrySet()){
if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
System.out.println(entry.getKey() + "-->" + entry.getValue());
}
}

i got the same problem so tried so many things but finally this is the solution.

If session.cookie_lifetime
is 0, the session cookie lives until the browser is quit.
EDIT: Others have mentioned the session.gc_maxlifetime
setting. When session garbage collection occurs, the garbage collector will delete any session data that has not been accessed in longer than session.gc_maxlifetime
seconds. To set the time-to-live for the session cookie, call session_set_cookie_params()
or define the session.cookie_lifetime
PHP setting. If this setting is greater than session.gc_maxlifetime
, you should increase session.gc_maxlifetime
to a value greater than or equal to the cookie lifetime to ensure that your sessions won't expire.
It looks much like a list of Django ORM model instances.
Why not sort them on query like this:
ut = Tag.objects.order_by('-count')
In your onCreate()
, write the following
LinearLayout myRoot = (LinearLayout) findViewById(R.id.my_root);
LinearLayout a = new LinearLayout(this);
a.setOrientation(LinearLayout.HORIZONTAL);
a.addView(view1);
a.addView(view2);
a.addView(view3);
myRoot.addView(a);
view1
, view2
and view3
are your TextView
s. They're easily created programmatically.
I use this as part of my utils. With this we can not only set shadow but also can get a rounded corner for any UIView
. Also you could set what color shadow you prefer. Normally black is preferred but sometimes, when the background is non-white you might want something else. Here's what I use -
in utils.m
+ (void)roundedLayer:(CALayer *)viewLayer
radius:(float)r
shadow:(BOOL)s
{
[viewLayer setMasksToBounds:YES];
[viewLayer setCornerRadius:r];
[viewLayer setBorderColor:[RGB(180, 180, 180) CGColor]];
[viewLayer setBorderWidth:1.0f];
if(s)
{
[viewLayer setShadowColor:[RGB(0, 0, 0) CGColor]];
[viewLayer setShadowOffset:CGSizeMake(0, 0)];
[viewLayer setShadowOpacity:1];
[viewLayer setShadowRadius:2.0];
}
return;
}
To use this we need to call this - [utils roundedLayer:yourview.layer radius:5.0f shadow:YES];
you can add method in LoginController add line use App\User;
on Top, after this add method, it is work for me wkwkwkwkw , but you must add {{ csrf_field() }}
on view admin and user
protected function authenticated(Request $request, $user){
$user=User::where('email',$request->input('email'))->pluck('jabatan');
$c=" ".$user." ";
$a=strcmp($c,' ["admin"] ');
if ($a==0) {
return redirect('admin');
}else{
return redirect('user');
}}
A common trick is to check like this:
trim(TextBox1.Value & vbnullstring) = vbnullstring
this will work for spaces, empty strings, and genuine null values
In Eclipse:
Right click on your build.xml
click "Run As", click on "External Tool Configurations..."
Select tab JRE. Select the JRE you are using.
Re-run the task, it should be fine now.
I had a column that did not allow nulls and I was inserting a null value.
if you are getting id from url try
$id = (isset($_GET['id']) ? $_GET['id'] : '');
if getting from form you need to use POST
method cause your form has method="post"
$id = (isset($_POST['id']) ? $_POST['id'] : '');
For php notices use isset()
or empty()
to check values exist or not or initialize variable first with blank or a value
$id= '';

Check that the connection string is in your Web.Config. I removed that node and put it in my Web.Debug.config and this is the error I received. Moved it back to the Web.config and worked great.
For some reason
if (strictBounds.contains(map.getCenter())) return;
didnt work for me (maybe a southern hemisphere issue). I had to change it to:
function checkBounds() {
var c = map.getCenter(),
x = c.lng(),
y = c.lat(),
maxX = strictBounds.getNorthEast().lng(),
maxY = strictBounds.getNorthEast().lat(),
minX = strictBounds.getSouthWest().lng(),
minY = strictBounds.getSouthWest().lat();
if(x < minX || x > maxX || y < minY || y > maxY) {
if (x < minX) x = minX;
if (x > maxX) x = maxX;
if (y < minY) y = minY;
if (y > maxY) y = maxY;
map.setCenter(new google.maps.LatLng(y, x));
}
}
Hope it will help someone.

The JVM abstracts from the concrete platform. Your program relies only upon the JVM and since the JVM is available for different platforms like Windows and Linux, your program is platform independent (but jvm depended).
See the MSDN reference table for maximum numbers/sizes.
Bytes per varchar(max), varbinary(max), xml, text, or image column: 2^31-1
There's a two-byte overhead for the column, so the actual data is 2^31-3 max bytes in length. Assuming you're using a single-byte character encoding, that's 2^31-3 characters total. (If you're using a character encoding that uses more than one byte per character, divide by the total number of bytes per character. If you're using a variable-length character encoding, all bets are off.)
If every element in b has different lengths, then you need to do something like:
int totalLength = 0;
for_every_element_in_b {
totalLength += length_of_this_b_in_bytes;
}
return (char **)malloc(totalLength);
this is one:
ls -l . | egrep -c '^-'
Note:
ls -1 | wc -l
Which means:
ls
: list files in dir
-1
: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too
|
: pipe output onto...
wc
: "wordcount"
-l
: count l
ines.
"Sleep" state connections are most often created by code that maintains persistent connections to the database.
This could include either connection pools created by application frameworks, or client-side database administration tools.
As mentioned above in the comments, there is really no reason to worry about these connections... unless of course you have no idea where the connection is coming from.
(CAVEAT: If you had a long list of these kinds of connections, there might be a danger of running out of simultaneous connections.)
You should change the query to:
SELECT time_col, COUNT(time_col) As Count
FROM time_table
WHERE activity_col = 3
GROUP BY time_col
This vl works correctly.
First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).
If your data is not large, you can do
SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'
using OR
if you have multiple keywords.
implementation 'com.android.support:appcompat-v7:28.0'

All to add
Here is the simplest solution
select m_id,v_id,max(timestamp) from table group by m_id;
Group by m_id but get max of timestamp for each m_id.
You can rename the file using FSO by moving it: MoveFile Method.
Dim Fso
Set Fso = WScript.CreateObject("Scripting.FileSystemObject")
Fso.MoveFile "A.txt", "B.txt"
If you are already connected, simply type this in the javascript console:
FB.getAuthResponse()['accessToken']
You can also use tidy, which may need to be installed first (e.g. on Ubuntu: sudo apt-get install tidy
).
For this, you would issue something like following:
tidy -xml -i your-file.xml > output.xml
Note: has many additional readability flags, but word-wrap behavior is a bit annoying to untangle (http://tidy.sourceforge.net/docs/quickref.html).
You can get the results with a simple:
@app.route('your route', methods=['GET'])
def yourMethod(params):
response = flask.jsonify({'some': 'data'})
response.headers.add('Access-Control-Allow-Origin', '*')
return response
I have used this:
mongorestore -d databasename -c file.bson fullpath/file.bson
1.copy the file path and file name from properties (try to put all bson files in different folder), 2.use this again and again with changing file name only.
If it's not a big/long array just mirror it:
for( int i = 0; i < arr.length/2; ++i )
{
temp = arr[i];
arr[i] = arr[arr.length - i - 1];
arr[arr.length - i - 1] = temp;
}
Since I find myself rather regularly looking for this exact problem (in the hopes I missed something before...), I finally decided to take the time and write up a small gist to export MySQL queries as CSV files, kinda like https://stackoverflow.com/a/28168869 but based on PHP and with a couple of more options. This was important for my use case, because I need to be able to fine-tune the CSV parameters (delimiter, NULL value handling) AND the files need to be actually valid CSV, so that a simple CONCAT
is not sufficient since it doesn't generate valid CSV files if the values contain line breaks or the CSV delimiter.
Caution: Requires PHP to be installed on the server!
(Can be checked via php -v
)
"Install" mysql2csv
via
wget https://gist.githubusercontent.com/paslandau/37bf787eab1b84fc7ae679d1823cf401/raw/29a48bb0a43f6750858e1ddec054d3552f3cbc45/mysql2csv -O mysql2csv -q && (sha256sum mysql2csv | cmp <(echo "b109535b29733bd596ecc8608e008732e617e97906f119c66dd7cf6ab2865a65 mysql2csv") || (echo "ERROR comparing hash, Found:" ;sha256sum mysql2csv) ) && chmod +x mysql2csv
(download content of the gist, check checksum and make it executable)
Usage example
./mysql2csv --file="/tmp/result.csv" --query='SELECT 1 as foo, 2 as bar;' --user="username" --password="password"
generates file /tmp/result.csv
with content
foo,bar
1,2
help for reference
./mysql2csv --help
Helper command to export data for an arbitrary mysql query into a CSV file.
Especially helpful if the use of "SELECT ... INTO OUTFILE" is not an option, e.g.
because the mysql server is running on a remote host.
Usage example:
./mysql2csv --file="/tmp/result.csv" --query='SELECT 1 as foo, 2 as bar;' --user="username" --password="password"
cat /tmp/result.csv
Options:
-q,--query=name [required]
The query string to extract data from mysql.
-h,--host=name
(Default: 127.0.0.1) The hostname of the mysql server.
-D,--database=name
The default database.
-P,--port=name
(Default: 3306) The port of the mysql server.
-u,--user=name
The username to connect to the mysql server.
-p,--password=name
The password to connect to the mysql server.
-F,--file=name
(Default: php://stdout) The filename to export the query result to ('php://stdout' prints to console).
-L,--delimiter=name
(Default: ,) The CSV delimiter.
-C,--enclosure=name
(Default: ") The CSV enclosure (that is used to enclose values that contain special characters).
-E,--escape=name
(Default: \) The CSV escape character.
-N,--null=name
(Default: \N) The value that is used to replace NULL values in the CSV file.
-H,--header=name
(Default: 1) If '0', the resulting CSV file does not contain headers.
--help
Prints the help for this command.
From android API Level 19, when I want to instance JSONArray object I put JSONObject directly as parameter like below:
JSONArray jsonArray=new JSONArray(jsonObject);
JSONArray has constructor to accept object.
public static boolean compareList(List ls1, List ls2){
return ls1.containsAll(ls2) && ls1.size() == ls2.size() ? true :false;
}
public static void main(String[] args) {
ArrayList<String> one = new ArrayList<String>();
one.add("one");
one.add("two");
one.add("six");
ArrayList<String> two = new ArrayList<String>();
two.add("one");
two.add("six");
two.add("two");
System.out.println("Output1 :: " + compareList(one, two));
two.add("ten");
System.out.println("Output2 :: " + compareList(one, two));
}
How is 0.2999999999999998 an acceptable answer? If I were the asker I would want an answer of .3. What we have here is false precision, and my experiments with floor, %, etc indicate that Javascript is fond of false precision for these operations. So I think the answers that are using conversion to string are on the right track.
I would do this:
var decPart = (n+"").split(".")[1];
Specifically, I was using 100233.1 and I wanted the answer ".1".
Go to the "Server" view, then double-click the Tomcat server you're running. The access log files are stored relative to the path in the "Server path" field, which itself is relative to the workspace path.
Your syntax error is caused by a missing "table" in the query
ALTER TABLE mytable MODIFY mycolumn varchar(255) null;
I think that I got a solution for this. You don't have to start monitor but you can use DDMS instead almost like in Eclipse.
Start Android Studio-> pick breakpoint-> Run-> Debug-> Go to %sdk\tools in Terminal window and run ddms.bat to run DDMS without Monitor running (since it won't let you run ADB). You can now start profiling or debug step-by-step.
Hope this helps you.

This question has many, many duplicates, including questions not mentioning the Chai assertion library. Here are the basics collected together:
The assertion must call the function, instead of it evaluating immediately.
assert.throws(x.y.z);
// FAIL. x.y.z throws an exception, which immediately exits the
// enclosing block, so assert.throw() not called.
assert.throws(()=>x.y.z);
// assert.throw() is called with a function, which only throws
// when assert.throw executes the function.
assert.throws(function () { x.y.z });
// if you cannot use ES6 at work
function badReference() { x.y.z }; assert.throws(badReference);
// for the verbose
assert.throws(()=>model.get(z));
// the specific example given.
homegrownAssertThrows(model.get, z);
// a style common in Python, but not in JavaScript
You can check for specific errors using any assertion library:
assert.throws(() => x.y.z);
assert.throws(() => x.y.z, ReferenceError);
assert.throws(() => x.y.z, ReferenceError, /is not defined/);
assert.throws(() => x.y.z, /is not defined/);
assert.doesNotThrow(() => 42);
assert.throws(() => x.y.z, Error);
assert.throws(() => model.get.z, /Property does not exist in model schema./)
should.throws(() => x.y.z);
should.throws(() => x.y.z, ReferenceError);
should.throws(() => x.y.z, ReferenceError, /is not defined/);
should.throws(() => x.y.z, /is not defined/);
should.doesNotThrow(() => 42);
should.throws(() => x.y.z, Error);
should.throws(() => model.get.z, /Property does not exist in model schema./)
expect(() => x.y.z).to.throw();
expect(() => x.y.z).to.throw(ReferenceError);
expect(() => x.y.z).to.throw(ReferenceError, /is not defined/);
expect(() => x.y.z).to.throw(/is not defined/);
expect(() => 42).not.to.throw();
expect(() => x.y.z).to.throw(Error);
expect(() => model.get.z).to.throw(/Property does not exist in model schema./);
You must handle exceptions that 'escape' the test
it('should handle escaped errors', function () {
try {
expect(() => x.y.z).not.to.throw(RangeError);
} catch (err) {
expect(err).to.be.a(ReferenceError);
}
});
This can look confusing at first. Like riding a bike, it just 'clicks' forever once it clicks.
With most .net unit testing frameworks you can put an [ExpectedException] attribute on the test method. However this can't tell you that the exception happened at the point you expected it to. That's where xunit.net can help.
With xunit you have Assert.Throws, so you can do things like this:
[Fact]
public void CantDecrementBasketLineQuantityBelowZero()
{
var o = new Basket();
var p = new Product {Id = 1, NetPrice = 23.45m};
o.AddProduct(p, 1);
Assert.Throws<BusinessException>(() => o.SetProductQuantity(p, -3));
}
[Fact] is the xunit equivalent of [TestMethod]
a.hover:hover
Here is one more reason why this can happen. Perhaps this can help someone else. Notice the difference, Members vs Member. They must be the same...
export default mongoose.models.Members || mongoose.model('Member', FamilySchema)
Change to:
export default mongoose.models.Member || mongoose.model('Member', FamilySchema)
The main reason you use the default queue over the main queue is to run tasks in the background.
For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
//Background Thread
dispatch_async(dispatch_get_main_queue(), ^(void){
//Run UI Updates
});
});
The stopPropagation()
method stops the bubbling of an event to parent elements, preventing any parent handlers from being notified of the event.
You can use the method event.isPropagationStopped()
to know whether this method was ever called (on that event object).
Syntax:
Here is the simple syntax to use this method:
event.stopPropagation()
Example:
$("div").click(function(event) {
alert("This is : " + $(this).prop('id'));
// Comment the following to see the difference
event.stopPropagation();
});?
I just posted a slight variation on some of the examples above on another thread (Finding perfect squares) and thought I'd include a slight variation of what I posted there here (using nsqrt as a temporary variable), in case it's of interest / use:
import math
def is_square(n):
if not (isinstance(n, int) and (n >= 0)):
return False
else:
nsqrt = math.sqrt(n)
return nsqrt == math.trunc(nsqrt)
It is incorrect for a large non-square such as 152415789666209426002111556165263283035677490.
Here is an example
import numpy as np
import matplotlib.pyplot as plt
x = np.random.rand(100)
y = np.random.rand(100)
t = np.arange(100)
plt.scatter(x, y, c=t)
plt.show()
Here you are setting the color based on the index, t
, which is just an array of [1, 2, ..., 100]
.
Perhaps an easier-to-understand example is the slightly simpler
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(100)
y = x
t = x
plt.scatter(x, y, c=t)
plt.show()
Note that the array you pass as c
doesn't need to have any particular order or type, i.e. it doesn't need to be sorted or integers as in these examples. The plotting routine will scale the colormap such that the minimum/maximum values in c
correspond to the bottom/top of the colormap.
You can change the colormap by adding
import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.cmap_name)
Importing matplotlib.cm
is optional as you can call colormaps as cmap="cmap_name"
just as well. There is a reference page of colormaps showing what each looks like. Also know that you can reverse a colormap by simply calling it as cmap_name_r
. So either
plt.scatter(x, y, c=t, cmap=cm.cmap_name_r)
# or
plt.scatter(x, y, c=t, cmap="cmap_name_r")
will work. Examples are "jet_r"
or cm.plasma_r
. Here's an example with the new 1.5 colormap viridis:
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(100)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')
plt.show()
You can add a colorbar by using
plt.scatter(x, y, c=t, cmap='viridis')
plt.colorbar()
plt.show()
Note that if you are using figures and subplots explicitly (e.g. fig, ax = plt.subplots()
or ax = fig.add_subplot(111)
), adding a colorbar can be a bit more involved. Good examples can be found here for a single subplot colorbar and here for 2 subplots 1 colorbar.
The problem of most of the answers, that they are good for unique items in list. If items are not unique and you still want to know whether there is an intersection, you should count items:
from collections import Counter as count
def listContains(l1, l2):
list1 = count(l1)
list2 = count(l2)
return list1&list2 == list1
print( listContains([1,1,2,5], [1,2,3,5,1,2,1]) ) # Returns True
print( listContains([1,1,2,8], [1,2,3,5,1,2,1]) ) # Returns False
You can also return the intersection by using ''.join(list1&list2)
You need to make the object first, then use []
to set it.
var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);
UPDATE 2018:
If you're able to use ES6 and Babel, you can use this new feature:
{
[yourKeyVariable]: someValueArray,
}
You don't need those imports. The only thing you need in your urls.py (to start) is:
from django.conf.urls.defaults import *
# This two if you want to enable the Django Admin: (recommended)
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
# ... your url patterns
)
NOTE: This solution was intended for Django <1.6. This was actually the code generated by Django itself. For newer version, see Jacob Hume's answer.
Use jline3:
Example:
Terminal terminal = TerminalBuilder.builder()
.jna(true)
.system(true)
.build();
// raw mode means we get keypresses rather than line buffered input
terminal.enterRawMode();
reader = terminal .reader();
...
int read = reader.read();
....
reader.close();
terminal.close();
Use :
<EditText
..
android:drawableStart="@drawable/icon" />
>>> import socket
>>> socket.gethostbyaddr("69.59.196.211")
('stackoverflow.com', ['211.196.59.69.in-addr.arpa'], ['69.59.196.211'])
For implementing the timeout on the function, this stackoverflow thread has answers on that.
It isn't possible as far as I can tell, since a link needs HTML, and mailto links don't create an HTML email.
This is probably for security as you could add javascript or iframes to this link and the email client might open up the end user for vulnerabilities.
Replaced the reader declaration with this one and now it works!
Dim reader As New StreamReader(filetoimport.Text, Encoding.Default)
Encoding.Default represents the ANSI code page that is set under Windows Control Panel.
To add a button programatically to your controller's view, use the following:
-(void)viewDidLoad
{
UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(0, 0, 100, 50);
[btn setTitle:@"Hello, world!" forState:UIControlStateNormal];
[self.view addSubview:btn];
}
To add three of these, rinse and repeat.
Each WebDriver has a .save_screenshot(filename)
method. So for Firefox, it can be used like this:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')
Confusingly, a .get_screenshot_as_file(filename)
method also exists that does the same thing.
There are also methods for: .get_screenshot_as_base64()
(for embedding in HTML) and .get_screenshot_as_png()
(for retrieving binary data).
And note that WebElements have a .screenshot()
method that works similarly, but only captures the selected element.

2.From the Recovery Partition, click Utilities from the menu bar, and then select Terminal.
3.Enter the following command into Terminal and press Enter to execute it: csrutil disable
4.Once the command has executed, exit the Terminal and reboot the Mac. When you log back into OS X, SIP will be disabled.
Answer given is almost correct just missing some pointers which i'll be taking care of in my solution
First make sure your user have a sudo access if not you can use the below command to add your user as sudo user :-
sudo adduser <username> sudo
The change will take effect the next time the user logs in.
i) Now go to sudo vim /etc/postgresql/<your_postgres_version>/main/pg_hba.conf
file and look for line that says :
local all postgres md5 #peer
and comment that. Just below that line there must be a commented line that says:
local all postgres peer
or for older versions it'll be :-
local all postgres ident
Uncomment that line.
ii) Now restart the postgres by using any of these commands :-
sudo /etc/init.d/postgresql restart
OR
sudo service postgresql restart
iii) Now you can simply log into postgres using the following command :
sudo -u postgres psql
iv) once you're in you can create any operation you want to in my case i wanted to create a new database you can do the same using below command :
CREATE DATABASE airflow_replica;
Found the port esp32 was connected to by -
ls /dev/*
You would get a long list and you can find the port you need
I know its too late now. However even today if you are having trouble accessing cross thread controls? This is the shortest answer till date :P
Invoke(new Action(() =>
{
label1.Text = "WooHoo!!!";
}));
This is how i access any form control from a thread.
The exception is thrown if
InvocationTargetException - if the underlying method throws an exception.
So if the method, that has been invoked with reflection API, throws an exception (runtime exception for example), the reflection API will wrap the exception into an InvocationTargetException
.
The split
method will create an array. So you need to access the third element in your case..
(arrays are 0-indexed) You need to access result[2]
to get the url
var result = $(row).text().split('|');
alert( result[2] );
You do not give us enough information to know what row
is, exactly.. So depending on how you acquire the variable row
you might need to do one of the following.
row
is a string then row.split('|');
$(row).text().split('|');
input
element then $(row).val().split('|');
You can use
set define off
Using this it won't prompt for the input
The -Xmx
argument defines the max memory size that the heap can reach for the JVM. You must know your program well and see how it performs under load and set this parameter accordingly. A low value can cause OutOfMemoryExceptions or a very poor performance if your program's heap memory is reaching the maximum heap size. If your program is running in dedicated server you can set this parameter higher because it wont affect other programs.
The -Xms
argument sets the initial heap memory size for the JVM. This means that when you start your program the JVM will allocate this amount of memory instantly. This is useful if your program will consume a large amount of heap memory right from the start. This avoids the JVM to be constantly increasing the heap and can gain some performance there. If you don't know if this parameter is going to help you, don't use it.
In summary, this is a compromise that you have to decide based only in the memory behavior of your program.
You have 2 options delete
and truncate
:
delete from mytable
This will delete all the content of the table, not reseting the autoincremental id, this process is very slow. If you want to delete specific records append a where clause at the end.
truncate myTable
This will reset the table i.e. all the auto incremental fields will be reset. Its a DDL and its very fast. You cannot delete any specific record through truncate
.
By checking other answers, I used object-fit in CSS:
video {
object-fit: fill;
}
From MDN (https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit):
The object-fit CSS property specifies how the contents of a replaced element should be fitted to the box established by its used height and width.
Value: fill
The replaced content is sized to fill the element’s content box: the object’s concrete object size is the element’s used width and height.
jQuery can handle JSONP, just pass an url formatted with the callback=? parameter to the $.getJSON
method, for example:
$.getJSON("https://api.ipify.org/?format=json", function(e) {_x000D_
console.log(e.ip);_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
_x000D_
This example is of a really simple JSONP service implemented on with api.ipify.org
.
If you aren't looking for a cross-domain solution the script can be simplified even more, since you don't need the callback parameter, and you return pure JSON.
Simply call the ordinal()
method on an enum value, to retrieve its corresponding number. There's no need to declare an addition attribute with its value, each enumerated value gets its own number by default, assigned starting from zero, incrementing by one for each value in the same order they were declared.
You shouldn't depend on the int
value of an enum
, only on its actual value. Enums in Java are a different kind of monster and are not like enums in C, where you depend on their integer code.
Regarding the example you provided in the question, Font.PLAIN
works because that's just an integer constant of the Font class. If you absolutely need a (possibly changing) numeric code, then an enum
is not the right tool for the job, better stick to numeric constants.
You would do that when the responsibility of creating/updating the referenced column isn't in the current entity, but in another entity.
Create a concrete class that inherits the abstract class and then test the functions the concrete class inherits from the abstract class.
How about: hasattr(a, "__iter__")
?
It tells if the object returned can be iterated over as a generator. By default, tuples and lists can, but not the string types.
I use cx_Freeze. Works with Python 2 and 3, and I have tested it to work on Windows, Mac, and Linux.
cx_Freeze: http://cx-freeze.sourceforge.net/
Try this one:
private String toDate() {
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
// Create a calendar object with today date. Calendar is in java.util pakage.
Calendar calendar = Calendar.getInstance();
// Move calendar to yesterday
calendar.add(Calendar.DATE, -1);
// Get current date of calendar which point to the yesterday now
Date yesterday = calendar.getTime();
return dateFormat.format(yesterday).toString();
}
I see you are using jQuery for the form initialization.
When I try @KyungHun Jeon's answer, it doesn't work for me that use jQuery too.
So, I tried appending the form to the body by using the jQuery way:
$(document.body).append(form);
And it worked!
Apparently, document.addEventListener()
is unreliable, and hence, my error. Use window.addEventListener()
with the same parameters, instead.
Option #1
Instead of picking the binary/raw data into a variable and then writing, you can use CURLOPT_FILE
option to directly show a file to the curl for the downloading.
Here is the function:
// takes URL of image and Path for the image as parameter
function download_image1($image_url, $image_file){
$fp = fopen ($image_file, 'w+'); // open file handle
$ch = curl_init($image_url);
// curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
curl_setopt($ch, CURLOPT_FILE, $fp); // output to file
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 1000); // some large value to allow curl to run for a long time
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
// curl_setopt($ch, CURLOPT_VERBOSE, true); // Enable this line to see debug prints
curl_exec($ch);
curl_close($ch); // closing curl handle
fclose($fp); // closing file handle
}
And here is how you should call it:
// test the download function
download_image1("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2", "local_image1.jpg");
Option #2
Now, If you want to download a very large file, that case above function may not become handy. You can use the below function this time for handling a big file. Also, you can print progress(in %
or in any other format) if you want. Below function is implemented using a callback
function that writes a chunk of data in to the file in to the progress of downloading.
// takes URL of image and Path for the image as parameter
function download_image2($image_url){
$ch = curl_init($image_url);
// curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 1000); // some large value to allow curl to run for a long time
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
curl_setopt($ch, CURLOPT_WRITEFUNCTION, "curl_callback");
// curl_setopt($ch, CURLOPT_VERBOSE, true); // Enable this line to see debug prints
curl_exec($ch);
curl_close($ch); // closing curl handle
}
/** callback function for curl */
function curl_callback($ch, $bytes){
global $fp;
$len = fwrite($fp, $bytes);
// if you want, you can use any progress printing here
return $len;
}
And here is how to call this function:
// test the download function
$image_file = "local_image2.jpg";
$fp = fopen ($image_file, 'w+'); // open file handle
download_image2("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2");
fclose($fp); // closing file handle
x//1
The //
operator returns the floor of the division. Since dividing by 1 doesn't change your number, this is equivalent to floor but no import is needed.
Notes:
result = []
# Make a set of your "types":
input_set = set([tpl[1] for tpl in input])
>>> set(['ETH', 'KAT', 'NOT'])
# Iterate over the input_set
for type_ in input_set:
# a dict to gather things:
D = {}
# filter all tuples from your input with the same type as type_
tuples = filter(lambda tpl: tpl[1] == type_, input)
# write them in the D:
D["type"] = type_
D["itmes"] = [tpl[0] for tpl in tuples]
# append D to results:
result.append(D)
result
>>> [{'itmes': ['9085267', '11788544'], 'type': 'NOT'}, {'itmes': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}, {'itmes': ['11013331', '9843236'], 'type': 'KAT'}]
You can use git stash
. You have to specify --include-untracked
, otherwise you'll end up with the original problem.
git stash --include-untracked
Then just drop the last entry in the stash
git stash drop
You can make a handy-dandy alias for that, and call it git discard
for example:
git config --global alias.discard "! git stash -q --include-untracked && git stash drop -q"
Vertical alignment only works with inline or inline-block elements, and it's only relative to other inline[-block] elements. Because you float the label, it becomes a block element.
The simplest solution in your case is to set the label to display: inline-block
and add vertical-align: middle
to the labels and the inputs. (You might find that the height of the text is such that vertical align won't make any difference anyway.)
getColor() is depreceted
So try this way:
tv_title.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.sf_white));
BrixenDK is right.
.ajaxStop()
callback executed when all ajax call completed. This is a best place to put your handler.
$(document).ajaxStop(function(){
window.location.reload();
});
If you have installed the Portable version of Chrome, or have it installed in a custom directory - the extensions won't be available in directory referenced in above answers.
Try right-clicking on Chrome's shortcut & Check the "Target" directory. From there, navigate to one directory above and you should be able to see the User Data
folder and then can use the answers mentioned above
We used to do this with ANSI terminal codes. Not sure if they still work, but you could try them.
I assume this is running on a server where the zip application is in the search path. Should be true for all unix-based and I guess most windows-based servers.
exec('zip -r archive.zip "My folder"');
unlink('My\ folder/index.html');
unlink('My\ folder/picture.jpg');
The archive will reside in archive.zip afterwards. Keep in mind that blanks in file or folder names are a common cause of errors and should be avoided where possible.
For others having the same problem, try running
git add .
which will add all files of the current directory to track (including untracked) and then use
git commit -a
to commit all tracked files.
As suggested by @Pacerier, one liner that does the same thing is
git add -A
I use char 'f', 'm' and 'u' because I surmise the gender from name, voice and conversation, and sometimes don't know the gender. The final determination is their opinion.
It really depends how well you know the person and whether your criteria is physical form or personal identity. A psychologist might need additional options - cross to female, cross to male, trans to female, trans to male, hermaphrodite and undecided. With 9 options, not clearly defined by a single character, I might go with Hugo's advice of tiny integer.
Try delete
:
models.User.query.delete()
From the docs: Returns the number of rows deleted, excluding any cascades.
Ibrahim's comment on the other answer is the correct way to alter an existing user's home directory.
usermod -d /newhome/username username
usermod
is the command to edit an existing user.
-d
(abbreviation for --home
) will change the user's home directory.
usermod -m -d /newhome/username username
-m
(abbreviation for --move-home
) will move the content from the user's current directory to the new directory.
The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:
A data frame of four rows:
df = pd.DataFrame({'A': [1,2,3,4]})
Now trying to assign a list/array of two elements to it:
df['B'] = [3,4] # or df['B'] = np.array([3,4])
Both errors out:
ValueError: Length of values does not match length of index
Because the data frame has four rows but the list and array has only two elements.
Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:
df['B'] = pd.Series([3,4])
df
# A B
#0 1 3.0
#1 2 4.0
#2 3 NaN # NaN because the value at index 2 and 3 doesn't exist in the Series
#3 4 NaN
For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:
df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))
# A B
#0 1 1.0
#1 2 5.0
#2 7 9.0
#3 8 NaN
One approach is to combine the search strings into a regex pattern as in this answer.
For some databases, you can just explicitly insert a NULL
into the auto_increment
column:
INSERT INTO table_name VALUES (NULL, 'my name', 'my group')

The Base Pointer points to the offset address of the extra segment. The Instruction Pointer points to the offset address of the code segment. Now, about the segments...they are small 64KB divisions of the processors memory area.....This process is known as Memory Segmentation. I hope this post was helpful.

Virtual classes are not the same as virtual inheritance. Virtual classes you cannot instantiate, virtual inheritance is something else entirely.

What is the difference between them?
Image: the generic Linux kernel binary image file.
zImage: a compressed version of the Linux kernel image that is self-extracting.
uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.
Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:
Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.
(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)
Which type of kernel image do I have to use?
You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.
ADDENDUM
I know that u-boot needs a kernel in uImage format.
That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.
If you use the HtmlUnitDriver
, you can set request headers by modifying the WebClient
, like so:
final case class Header(name: String, value: String)
final class HtmlUnitDriverWithHeaders(headers: Seq[Header]) extends HtmlUnitDriver {
super.modifyWebClient {
val client = super.getWebClient
headers.foreach(h => client.addRequestHeader(h.name, h.value))
client
}
}
The headers will then be on all requests made by the web browser.
Is there a System.Web.WebPages.Razor.dll in the bin folder of your web app? What is its version? (Explorer right click, properties) I'm guessing it's not 3.0.0.0. Just get the nuget packages for v3.0.0.0, perhaps by copying the packages folder from your colleague. Or install it manually: http://www.nuget.org/packages/Microsoft.AspNet.Mvc/3.0.20105.1
EDIT: if you copy stuff from your colleague, also copy the relevant version numbers into packages.config. This is what tells nuget which versions to put into the packages folder.
The style attribute in React expect the value to be an object, ie Key value pair.
style = {}
will have another object inside it like {float:'right'}
to make it work.
<span style={{float:'right'}}>{'Download Audit'}</span>
Hope this solves the problem
you can also skip creating dictionary altogether. i used below approach to same problem .
mappedItems: {};
items.forEach(item => {
if (mappedItems[item.key]) {
mappedItems[item.key].push({productId : item.productId , price : item.price , discount : item.discount});
} else {
mappedItems[item.key] = [];
mappedItems[item.key].push({productId : item.productId , price : item.price , discount : item.discount}));
}
});

url: "{controller}/{action}/{id}",
defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });
}
IF still not working then do below steps
Second Way : You simple follow below steps,
1) Right click on your Project
2) Select Properties
3) Select Web option and then Select Specific Page (Controller/View) and then set your login page
Here, Account is my controller and Login is my action method (saved in Account Controller)

count_missings(spark_df)
# | Col_A | 10 |
# | Col_C | 2 |
# | Col_B | 1 |
If you don't want ordering and see them as a single row:
count_missings(spark_df, False)
# | Col_A | Col_B | Col_C |

A ListView
is basically like a ListBox
(and inherits from it), but it also has a View
property. This property allows you to specify a predefined way of displaying the items. The only predefined view in the BCL (Base Class Library) is GridView
, but you can easily create your own.
Another difference is the default selection mode: it's Single
for a ListBox
, but Extended
for a ListView
