This is a way:
Using apktool
to decode:
$ apktool d -f {apkfile} -o {output folder}
Next, using JADX (at github.com/skylot/jadx)
$ jadx -d {output folder} {apkfile}
2 tools extract and decompiler to same output folder.
Playing with JavaScript in an HTA I had no luck with a driver={SQL Server};...
connection string, but a named DSN was OK :
I set up TestDSN and it tested OK, and then var strConn= "DSN=TestDSN";
worked, so I carried on experimenting for my in-house testing and learning purposes.
Our server has several instances running, e.g. server1\dev and server1\Test which made things slightly more tricky as I managed to waste some time forgetting to escape the \
as \\
:)
After some dead-ends with server=server1;instanceName=dev
in the connection strings, I eventually got this one to work :
var strConn= "Provider=SQLOLEDB;Data Source=server1\\dev;Trusted_Connection=Yes;Initial Catalog=MyDatabase;"
Using Windows credentials rather than supplying a user/pwd, I found an interesting diversion was discovering the subtleties of Integrated Security = true
v Integrated Security = SSPI
v Trusted_Connection=Yes
- see Difference between Integrated Security = True and Integrated Security = SSPI
Beware that RecordCount will come back as -1
if using the default adOpenForwardOnly type. If you're working with small result sets and/or don't mind the whole lot in memory at once, use rs.Open(strQuery, objConnection, 3);
(3=adOpenStatic) and this gives a valid rs.RecordCount
It is worth noting that sizeof
doesn't help when dealing with an array value that has decayed to a pointer: even though it points to the start of an array, to the compiler it is the same as a pointer to a single element of that array. A pointer does not "remember" anything else about the array that was used to initialize it.
int a[10];
int* p = a;
assert(sizeof(a) / sizeof(a[0]) == 10);
assert(sizeof(p) == sizeof(int*));
assert(sizeof(*p) == sizeof(int));
I know this is an old question but it does not yet appear to have an answer. I've duplicated this situation, but I'm writing the server app, so I've been able to establish what happens on the server side as well. The client sends the certificate when the server asks for it and if it has a reference to a real certificate in the s_client command line. My server application is set up to ask for a client certificate and to fail if one is not presented. Here is the command line I issue:
Yourhostname here -vvvvvvvvvv
s_client -connect <hostname>:443 -cert client.pem -key cckey.pem -CAfile rootcert.pem -cipher ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH -tls1 -state
When I leave out the "-cert client.pem" part of the command the handshake fails on the server side and the s_client command fails with an error reported. I still get the report "No client certificate CA names sent" but I think that has been answered here above.
The short answer then is that the server determines whether a certificate will be sent by the client under normal operating conditions (s_client is not normal) and the failure is due to the server not recognizing the CA in the certificate presented. I'm not familiar with many situations in which two-way authentication is done although it is required for my project.
You are clearly sending a certificate. The server is clearly rejecting it.
The missing information here is the exact manner in which the certs were created and the way in which the provider loaded the cert, but that is probably all wrapped up by now.
To Solve this Error just initialize that variable above that loop or statement. For Example var a =""
Item collection.
$_item->product_type;
$_item->getId()
Product :
$product->getTypeId();
$product->getId()
"N/A" is not a string it is an error, try this:
=if(ISNA(A1),C1)
you have to place this fomula in cell B1 so it will get the value of your formula
You can do this,
User.query.filter_by(id=123).delete()
or
User.query.filter(User.id == 123).delete()
Make sure to commit
for delete()
to take effect.
I use this simple playbook:
---
# vars.yml

# ansible-playbook vars.yml -e 'hosts=localhost'
#
- hosts: localhost
tasks:
- fail: "You must specify a value for `hosts` variable - e.g.: ansible-playbook vars.yml -e 'hosts=localhost'"
when: hosts is not defined
- hosts: "{{ hosts }}"
tasks:
- debug: var=vars
- debug: var=hostvars[inventory_hostname]
With Docker v1.9 you can use the ARG instruction to fetch arguments passed by command line to the image on build action. Simply use the --build-arg flag. So you can avoid to keep explicit password (or other sensible information) on the Dockerfile and pass them on the fly.
source: https://docs.docker.com/engine/reference/commandline/build/ http://docs.docker.com/engine/reference/builder/#arg
Example:
Dockerfile
FROM busybox
ARG user
RUN echo "user is $user"
build image command
docker build --build-arg user=capuccino -t test_arguments -f path/to/dockerfile .
during the build it print
$ docker build --build-arg user=capuccino -t test_arguments -f ./test_args.Dockerfile .

If you wish, you can also use the column names instead of column numbers.
For example, if you want to read data from DataGridView on the 4. row and the "Name" column. It provides me a better understanding for which variable I am dealing with.
dataGridView.Rows[4].Cells["Name"].Value.ToString();
Hope it helps.
this will give you result that has the minimum price on all records.
SELECT *
FROM pieces
WHERE price = ( SELECT MIN(price) FROM pieces )
You can subclass the UITabBarController
, and replace the one with it in the storyboard.
In your viewDidLoad
implementation of subclass call this:
[self.tabBar setTintColor:[UIColor greenColor]];
My MAC OS Crashed recently. I reinstalled macOS 10.7.4 and Xcode 4.5. But all provisioning profiles were showing the following message in organizer
.
Valid Signing identity not found
I struggled to find help for a couple of days. Later I realized that if you have migrated from one system to another(or formatted your system), you need to export your private key from your keychain from your old system to the new system (or new OS installed).
One can also export your developer profile/team developer profile in organizer.
Organizer > Teams > Developer Profile > Export

The Scanner class is bases on logic implemented in String next(Pattern)
method. The additional API method like nextDouble()
or nextFloat()
. Provide the pattern inside.
Then class description says:
A simple text scanner which can parse primitive types and strings using regular expressions.
A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. The resulting tokens may then be converted into values of different types using the various next methods.
From the description it can be sad that someone has forgot about char as it is a primitive type for sure.
But the concept of class is to find patterns, a char has no pattern is just next character. And this logic IMHO caused that nextChar has not been implemented.
If you need to read a filed char by char you can used more efficient class.
You can wrap the contents of the li
in another element such as a span
. Then, give the li
a larger font-size
, and set a normal font-size
back on the span
:
li {
font-size: 36px;
}
li span {
font-size: 18px;
}
<ul>
<li><span>Item 1</span></li>
<li><span>Item 2</span></li>
<li><span>Item 3</span></li>
</ul>
If you use Django, it has a built in @classproperty

To turn arbitrary extended object reference into SHA-1, use simply git-rev-parse, for example
git rev-parse HEAD
or
git rev-parse --verify HEAD
You can also retrieve the short version like this
git rev-parse --short HEAD
Sidenote: If you want to turn references (branches and tags) into SHA-1, there is git show-ref
and git for-each-ref
.
If you want to use the autobuilder at hub.docker.com, it has to be Dockerfile
. So there :)
The accepted answer is still good, just a few remarks on newer features. Since python 3.6, you can handle encoding directly in check_output
, see documentation. This returns a string object now:
import subprocess
out = subprocess.check_output(["ls", "-l"], encoding="utf-8")
In python 3.7, a parameter capture_output
was added to subprocess.run(), which does some of the Popen/PIPE handling for us, see the python docs :
import subprocess
p2 = subprocess.run(["ls", "-l"], capture_output=True, encoding="utf-8")
p2.stdout
For Kotlin you can Try this.
var builder = NotificationCompat.Builder(this,CHANNEL_ID)
.setVibrate(longArrayOf(1000, 1000, 1000, 1000, 1000))
.setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
Yes, you can define an abstract class without an abstract method. However, if there is no method inside you might better go with an interface
new Uri(Request.RequestUri, RequestContext.VirtualPathRoot)
If you just want to rearrange dates from oldest to newest in r etc. you can always do:
dataframe <- dataframe[nrow(dataframe):1,]
It's saved me exporting in and out from excel just for sort on Yahoo Finance data.
I might consider using a dict
and re.sub
for something like this:
import re
repldict = {'zero':'0', 'one':'1' ,'temp':'bob','garage':'nothing'}
def replfunc(match):
return repldict[match.group(0)]
regex = re.compile('|'.join(re.escape(x) for x in repldict))
with open('file.txt') as fin, open('fout.txt','w') as fout:
for line in fin:
fout.write(regex.sub(replfunc,line))
This has a slight advantage to replace
in that it is a bit more robust to overlapping matches.
Well in the way this is a single page application, the solution used was:
load the content with AJAX, like any other controller, and then call:
angular.bootstrap($('#your_div_loaded_in_ajax'),["myApp","other_module"]);
Big O is a means to represent the upper bounds of any function. We generally use it for expressing the upper bounds of a function that tells the running time of an Algorithm.
Ex : f(n) = 2(n^2) +3n be a function representing the running time of a hypothetical algorithm, Big-O notation essentially gives the upper limit for this function which is O(n^2)
This notation basically tells us that, for any input 'n' the running time won't be greater than the value expressed by Big-O notation.
Also, agree with all the above detailed answers. Hope this helps !!

I also had an issue with this problem simply copy and pasting DATETIME fields from SQL Management Studio to Excel for manipulation. Excel has the correct value of the DATETIME (even if the formatting is applied after the paste), but by default doesn't have a built in format to show the SQL DATETIME. Here's the fix:
Right click the cell, and choose Format Cells. Choose Custom. In the Type: input field enter
yyyy-mm-dd hh:mm:ss.000

You're probably trying to to update the same row of the target table multiple times. I just encountered the very same problem in a merge statement I developed. Make sure your update does not touch the same record more than once in the execution of the merge.
I was designing a html email and had a similar problem. But having every cell with the fixed width is not what I want. I'd like to have the equal spacing between the contents of the columns, like the following
|---something---|---a very long thing---|---short---|
After a lot of trial and error, I came up with the following
<style>
.content {padding: 0 20px;}
</style>
table width="400"
tr
td
a.content something
td
a.content a very long thing
td
a.content short
Issues of concern:
Outlook 2007/2010/2013 don't support padding. Having the width of the table set will allow the widths of the columns to automatically set. This way, though the contents will not have equal spacing. They at least have some spacing between them.
Automatic width setting for table columns will not give equal spacing between the contents The padding added for the contents will force the equal spacing.
To get a more detailed description (which table/column references which table/column) you can run the following query:
SELECT uc.constraint_name||CHR(10)
|| '('||ucc1.TABLE_NAME||'.'||ucc1.column_name||')' constraint_source
, 'REFERENCES'||CHR(10)
|| '('||ucc2.TABLE_NAME||'.'||ucc2.column_name||')' references_column
FROM user_constraints uc ,
user_cons_columns ucc1 ,
user_cons_columns ucc2
WHERE uc.constraint_name = ucc1.constraint_name
AND uc.r_constraint_name = ucc2.constraint_name
AND ucc1.POSITION = ucc2.POSITION -- Correction for multiple column primary keys.
AND uc.constraint_type = 'R'
AND uc.constraint_name = 'SYS_C00381400'
ORDER BY ucc1.TABLE_NAME ,
uc.constraint_name;
From here.
You can use this:
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {

}
}, 10000);
For Stop the Handler, You can try this:
handler.removeCallbacksAndMessages(null);
I don't think they are reprinting paper books each year. The copyright of the year when the book was printed is valid in all next years.
The same principle should apply to web pages, too. However "the year when website was created" is a bit different. So, if you make changes to your web site - you are not done yet. Hence, when updating the site, you may want to update the copyright year.
If you are already doing databinding:
<asp:Calendar ID="Calendar1" runat="server" SelectedDate="<%# DateTime.Today %>" />
Will do it. This does require that somewhere you are doing a Page.DataBind() call (or a databind call on a parent control). If you are not doing that and you absolutely do not want any codebehind on the page, then you'll have to create a usercontrol that contains a calendar control and sets its selecteddate.
This error will also appear if you try to connect to an exposed port from within a Docker container, when nothing is actively serving the port.
On a host where nothing is listening/bound to that port you'd get a No connection could be made because the target machine actively refused it
error instead when making a request to a local URL that is not served, eg: localhost:5000
. However, if you start a container that binds to the port, but there is no server running inside of it actually serving the port, any requests to that port on localhost will result in:
[Errno 99] Cannot assign requested address
(if called from within the container), or[Errno 0] Error
(if called from outside of the container).You can reproduce this error and the behaviour described above as follows:
Start a dummy container (note: this will pull the python image if not found locally):
docker run --name serv1 -p 5000:5000 -dit python
Then for [Errno 0] Error
enter a Python console on host, while for [Errno 99] Cannot assign requested address
access a Python console on the container by calling:
docker exec -it -u 0 serv1 python
And then in either case call:
import urllib.request
urllib.request.urlopen('https://localhost:5000')
I concluded with treating either of these errors as equivalent to No connection could be made because the target machine actively refused it
rather than trying to fix their cause - although please advise if that's a bad idea.
I've spent over a day figuring this one out, given that all resources and answers I could find on the [Errno 99] Cannot assign requested address
point in the direction of binding to an occupied port, connecting to an invalid IP, sysctl
conflicts, docker network issues, TIME_WAIT
being incorrect, and many more things. Therefore I wanted to leave this answer here, despite not being a direct answer to the question at hand, given that it can be a common cause for the error described in this question.

I tried solutions from other threads. Adding M2 and M2_HOME at System variables, and even at User variables. Running cmd as admin. None of the methods worked.
But today I added entire path to maven bin to my System variables "PATH" (C:\Program Files (x86)\Apache Software Foundation\apache-maven-3.1.0\bin) besides other paths, and so far it's working good. Hopefully it'll stay that way.

If you aren't comfortable with using negative margins, check this out.
div {
position: fixed;
left: 50%;
bottom: 20px;
transform: translate(-50%, -50%);
margin: 0 auto;
}
<div>
Your Text
</div>
Especially useful when you don't know the width of the div.
align="center"
has no effect.
Since you have position:absolute
, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.
#manipulate {
position:absolute;
width:300px;
height:300px;
background:#063;
bottom:0px;
right:25%;
left:50%;
margin-left:-150px;
}
Add:
using System.Linq;
to the top of your file.
And then:
Car[] carList = ...
var carMake =
from item in carList
where item.Model == "bmw"
select item.Make;
or if you prefer the fluent syntax:
var carMake = carList
.Where(item => item.Model == "bmw")
.Select(item => item.Make);
Things to pay attention to:
item.Make
in the select
clause instead if s.Make
as in your code.item
and .Model
in your where
clause $deleted = $_POST['checkbox'];
$sql = "DELETE FROM $tbl_name WHERE id IN (".implode(",", $deleted ) . ")";
I know this is old, but maybe this will help someone else.
Do not log "new" values. Your existing table, GUESTS, has the new values. You'll have double entry of data, plus your DB size will grow way too fast that way.
I cleaned this up and minimized it for this example, but here is the tables you'd need for logging off changes:
CREATE TABLE GUESTS (
GuestID INT IDENTITY(1,1) PRIMARY KEY,
GuestName VARCHAR(50),
ModifiedBy INT,
ModifiedOn DATETIME
)
CREATE TABLE GUESTS_LOG (
GuestLogID INT IDENTITY(1,1) PRIMARY KEY,
GuestID INT,
GuestName VARCHAR(50),
ModifiedBy INT,
ModifiedOn DATETIME
)
When a value changes in the GUESTS table (ex: Guest name), simply log off that entire row of data, as-is, to your Log/Audit table using the Trigger. Your GUESTS table has current data, the Log/Audit table has the old data.
Then use a select statement to get data from both tables:
SELECT 0 AS 'GuestLogID', GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS] WHERE GuestID = 1
UNION
SELECT GuestLogID, GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS_LOG] WHERE GuestID = 1
ORDER BY ModifiedOn ASC
Your data will come out with what the table looked like, from Oldest to Newest, with the first row being what was created & the last row being the current data. You can see exactly what changed, who changed it, and when they changed it.
Optionally, I used to have a function that looped through the RecordSet (in Classic ASP), and only displayed what values had changed on the web page. It made for a GREAT audit trail so that users could see what had changed over time.
You can use compileall
in the terminal. The following command will go recursively into sub directories and make pyc files for all the python files it finds. The compileall module is part of the python standard library, so you don't need to install anything extra to use it. This works exactly the same way for python2 and python3.
python -m compileall .
I'm not familiar with postgresql, but in SQL Server or Oracle, using a subquery would work like below (in Oracle, the SELECT 0
would be SELECT 0 FROM DUAL
)
SELECT SUM(sub.value)
FROM
(
SELECT SUM(columnA) as value FROM my_table
WHERE columnB = 1
UNION
SELECT 0 as value
) sub
Maybe this would work for postgresql too?
If you happen to be using jQuery, you might want to give this a shot: http://api.jquery.com/category/deferred-object/
It allows you to defer the execution of your callback function until the ajax request (or any async operation) is completed. This can also be used to call a callback once several ajax requests have all completed.
Here is another simple solution using sed.
$ sed -i 's/all.*/& anotherthing/g' filename.txt
Explanation:
all.* means all lines started with 'all'.
& represent the match (ie the complete line that starts with 'all')
then sed replace the former with the later and appends the ' anotherthing' word
You must edit permission of data folder.
I use "Root Explorer" (see market) app on root mode.
On top select "Monunted as r/w"
then press over data folder (long click) and find Permission option
Have a somenthing like that
read write execute
User
Group
Others
Make sure that "Others" have a check for read
Then go Eclpse and try again.
Sorry about my english,I hope can help you.
//Code to Retrieve Text from the Dropdownlist
$('#selectOptions').change(function()
{
var selectOptions =$('#selectOptions option:selected');
if(selectOptions.length >0)
{
var resultString = "";
resultString = selectOptions.text();
}
});
I found a good way to do this with using a function and basic code. This is a code that accepts a string and counts the number of capital letters, lowercase letters and also 'other'. Other is classed as a space, punctuation mark or even Japanese and Chinese characters.
def check(count):
lowercase = 0
uppercase = 0
other = 0
low = 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'
upper = 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'
for n in count:
if n in low:
lowercase += 1
elif n in upper:
uppercase += 1
else:
other += 1
print("There are " + str(lowercase) + " lowercase letters.")
print("There are " + str(uppercase) + " uppercase letters.")
print("There are " + str(other) + " other elements to this sentence.")
Starting with git 2.10 (released 2016-09-03), it is not necessary to enumerate each text file separately. Git 2.10 fixed the behavior of text=auto together with eol=lf. Source.
.gitattributes
file in the root of your git repository:
* text=auto eol=lf
Add and commit it.
Afterwards, you can do following to steps and all files are normalized now:
git rm --cached -r . # Remove every file from git's index.
git reset --hard # Rewrite git's index to pick up all the new line endings.

I know it's been said already, but I'd highly recommend the requests
Python package.
If you've used languages other than python, you're probably thinking urllib
and urllib2
are easy to use, not much code, and highly capable, that's how I used to think. But the requests
package is so unbelievably useful and short that everyone should be using it.
First, it supports a fully restful API, and is as easy as:
import requests
resp = requests.get('http://www.mywebsite.com/user')
resp = requests.post('http://www.mywebsite.com/user')
resp = requests.put('http://www.mywebsite.com/user/put')
resp = requests.delete('http://www.mywebsite.com/user/delete')
Regardless of whether GET / POST, you never have to encode parameters again, it simply takes a dictionary as an argument and is good to go:
userdata = {"firstname": "John", "lastname": "Doe", "password": "jdoe123"}
resp = requests.post('http://www.mywebsite.com/user', data=userdata)
Plus it even has a built in JSON decoder (again, I know json.loads()
isn't a lot more to write, but this sure is convenient):
resp.json()
Or if your response data is just text, use:
resp.text
This is just the tip of the iceberg. This is the list of features from the requests site:
// New date object from millis
Date date = new Date(millis);
// formattter
SimpleDateFormat formatter= new SimpleDateFormat("HH:mm:ss.SSS");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
// Pass date object
String formatted = formatter.format(date );
See runnable example using input of 1200 ms.
You want to feed the create.sql
into sqlite3
from the shell, not from inside SQLite itself:
$ sqlite3 auction.db < create.sql
SQLite's version of SQL doesn't understand <
for files, your shell does.
The lightweight MooTools framework has one: http://demos.mootools.net/Slider

One way is to leave a raw_input() at the end so the script waits for you to press enter before it terminates.
The advantage of using raw_input() instead of msvcrt.* stuff is that the former is a part of standard Python (i.e. absolutely cross-platform). This also means that the script window will be alive after double-clicking on the script file icon, without the need to do
cmd /K python <script>
I asked this a while back. The answer is basically that it doesn't work. :(
Try this code in jquery
$(document).ready(function(){
$("a").click(function(){
var id=$(this).attr('href');
var value=$(id).text();
$(".target").text(value);
});
});
For powershell in Windows, you can add relative path + filename to --output
flag:
curl -L http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip
here build_firefox is relative folder.
It's an old question, but I found this can be done easily with Spacy. Once the document is read, a simple api similarity
can be used to find the cosine similarity between the document vectors.
import spacy
nlp = spacy.load('en')
doc1 = nlp(u'Hello hi there!')
doc2 = nlp(u'Hello hi there!')
doc3 = nlp(u'Hey whatsup?')
print doc1.similarity(doc2) # 0.999999954642
print doc2.similarity(doc3) # 0.699032527716
print doc1.similarity(doc3) # 0.699032527716
Instead of:
var host = req.get('host');
var origin = req.get('origin');
you can also use:
var host = req.headers.host;
var origin = req.headers.origin;
DO
$do$
BEGIN
IF EXISTS (SELECT FROM orders) THEN
DELETE FROM orders;
ELSE
INSERT INTO orders VALUES (1,2,3);
END IF;
END
$do$
There are no procedural elements in standard SQL. The IF
statement is part of the default procedural language PL/pgSQL. You need to create a function or execute an ad-hoc statement with the DO
command.
You need a semicolon (;
) at the end of each statement in plpgsql (except for the final END
).
You need END IF;
at the end of the IF
statement.
A sub-select must be surrounded by parentheses:
IF (SELECT count(*) FROM orders) > 0 ...
Or:
IF (SELECT count(*) > 0 FROM orders) ...
This is equivalent and much faster, though:
IF EXISTS (SELECT FROM orders) ...
The additional SELECT
is not needed. This does the same, faster:
DO
$do$
BEGIN
DELETE FROM orders;
IF NOT FOUND THEN
INSERT INTO orders VALUES (1,2,3);
END IF;
END
$do$
Though unlikely, concurrent transactions writing to the same table may interfere. To be absolutely sure, write-lock the table in the same transaction before proceeding as demonstrated.
In a generic Markdown document, use:
<style>body {text-align: right}</style>
or
<style>body {text-align: justify}</style>
Does not seem to work with Jupyter though.
It wasn't working for me. I run crontab with sudo, so I switched to root, did the above suggestions, and crontab would open in vim, but it still wouldn't from my user account. Finally I ran sudo select-editor
from the user account and that did the trick.
This example will help you to understand the React Life Cycle Hooks.
You can setState
in getDerivedStateFromProps
method i.e. static
and trigger the method after props change in componentDidUpdate
.
In componentDidUpdate
you will get 3rd param which returns from getSnapshotBeforeUpdate
.

This is how i do it.
$("input[name='title']").on({
"change keyup": function(e) {
var slug = $(this).val().split(" ").join("-").toLowerCase();
$("input[name='slug']").val(slug);
},
});
The relevant build.gradle file will then update automatically.
Open your build.gradle file and add a new build rule to the dependencies closure. For example, if you wanted to add Google Play Services, your project's dependencies section would look something like this:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:6.5.+'
}
In the Project panel, Control + click the module you want to add the dependency to and select Open Module Settings.
Select the Dependencies tab, followed by the + button in the bottom-left corner. You can choose from the following list of options:
You can then enter more information about the dependency you want to add to your project. For example, if you choose Library Dependency, Android Studio displays a list of libraries for you to choose from.
Once you've added your dependency, check your module-level build.gradle file. It should have automatically updated to include the new dependency.
"Not equals" can be expressed with the "not" operator !
and the standard .equals
.
if (a.equals(b)) // a equals b
if (!a.equals(b)) // a not equal to b
If your system is using dpkg and apt (debian, ubuntu, etc), try running the following commands in that order (be careful with the sudo rm
commands):
sudo apt-get -f install
sudo dpkg -P phpmyadmin
sudo rm -vf /etc/apache2/conf.d/phpmyadmin.conf
sudo rm -vfR /usr/share/phpmyadmin
sudo service apache2 restart
This question is quite older. The Questioner might have been turned into an experienced Java Developer by this time. Yet I want to add some opinion here which would help beginners.
For JDK 7 users, Here using
Objects.requireNotNull(object[, optionalMessage]);
is not safe. This function throws NullPointerException
if it finds null
object and which is a RunTimeException
.
That will terminate the whole program!!. So better check null
using ==
or !=
.
Also, use List
instead of Array
. Although access speed is same, yet using Collections
over Array
has some advantages like if you ever decide to change the underlying implementation later on, you can do it flexibly. For example, if you need synchronized access, you can change the implementation to a Vector
without rewriting all your code.
public static double calculateInventoryTotal(List<Book> books) {
if (books == null || books.isEmpty()) {
return 0;
}
double total = 0;
for (Book book : books) {
if (book != null) {
total += book.getPrice();
}
}
return total;
}
Also, I would like to upvote @1ac0 answer. We should understand and consider the purpose of the method too while writing. Calling method could have further logics to implement based on the called method's returned data.
Also if you are coding with JDK 8, It has introduced a new way to handle null check and protect the code from NullPointerException
. It defined a new class called Optional
. Have a look at this for detail
Finally, Pardon my bad English.
Consider using a subquery:
from p in context.ParentTable
let cCount =
(
from c in context.ChildTable
where p.ParentId == c.ChildParentId
select c
).Count()
select new { ParentId = p.Key, Count = cCount } ;
If the query types are connected by an association, this simplifies to:
from p in context.ParentTable
let cCount = p.Children.Count()
select new { ParentId = p.Key, Count = cCount } ;
For me, the issue was some plugin in my Visual Studio started forcing my application into x64 64bit mode, so the Oracle driver wasn't being found as I had Oracle 32bit installed.
So if you are having this issue, try running Visual Studio in safemode (devenv /safemode). I could find that it was looking in SYSWOW64 for the ic.dll file by using the ProcMon app by SysInternals/Microsoft.
Update: For me it was the Telerik JustTrace product that was causing the issue, it was probably hooking in and affecting the runtime version somehow to do tracing.
Update2: It's not just JustTrace causing an issue, JustMock is causing the same processor mode issue. JustMock is easier to fix though: Click JustMock-> Disable Profiler and then my web app's oracle driver runs in the correct CPU mode. This might be fixed by Telerik in the future.
Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
For self-hiding you can use getCmdPID.bat and windowMode.bat:
@echo off
echo --- self hiding bat ----
pause
call getCmdPid.bat
set PID=%errorlevel%
call windowMode.bat -pid %PID% -mode hidden
Here's my collection of ways to achieve that - and even more - where it was possible I've tried to return also the PID of the started process (all linked scripts can be downloaded and saved with whatever name you find convenient):
Example usage:
call IEXPhidden.bat "cmd /c myBat.bat" "argument"
Example usage:
call SCHPhidden.bat "cmd /c myBat.bat" "argument"
Example usage (for more info print the help with '-h'):
call ShellRunJS.bat "notepad.exe" -style 0 -wait no
Example usage (for more info print the help with '-h'):
call win32process.bat "notepad" -arguments "/A openFile.txt" -showWindows 0 -title "notepad"
Example usage (for more info print the help with '-h'):
call ProcessStartJS.bat "notepad" -arguments "/A openFile.txt" -style Hidden -directory "." -title "notepad" -priority Normal
function ready(fn){var d=document;(d.readyState=='loading')?d.addEventListener('DOMContentLoaded',fn):fn();}
Use like
ready(function(){
//some code
});
(function(fn){var d=document;(d.readyState=='loading')?d.addEventListener('DOMContentLoaded',fn):fn();})(function(){
//Some Code here
//DOM is avaliable
//var h1s = document.querySelector("h1");
});

I happened to be working in localhost , in windows 10, using WAMP, as it turns out, Wamp has a really accessible configuration interface to change the MySQL configuration. You just need to go to the Wamp panel, then to MySQL, then to settings and change the mode to sql-mode: none.(essentially disabling the strict mode) The following picture illustrates this.
Label without an onclick will behave as you would expect. It changes the input. What you relly want is to execute selectAll()
when you click on a label, right?
Then only add select all to the label onclick. Or wrap the input into the the label and assign onclick only for the label
<label for="check_all_1" onclick="selectAll(document.wizard_form, this);">
<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All">
Select All
</label>

If you're not too worried in accuracy after days, you can simply do the maths
function timeSince(when) { // this ignores months
var obj = {};
obj._milliseconds = (new Date()).valueOf() - when.valueOf();
obj.milliseconds = obj._milliseconds % 1000;
obj._seconds = (obj._milliseconds - obj.milliseconds) / 1000;
obj.seconds = obj._seconds % 60;
obj._minutes = (obj._seconds - obj.seconds) / 60;
obj.minutes = obj._minutes % 60;
obj._hours = (obj._minutes - obj.minutes) / 60;
obj.hours = obj._hours % 24;
obj._days = (obj._hours - obj.hours) / 24;
obj.days = obj._days % 365;
// finally
obj.years = (obj._days - obj.days) / 365;
return obj;
}
then timeSince(pastDate);
and use the properties as you like.
Otherwise you can use .getUTC*
to calculate it, but note it may be slightly slower to calculate
function timeSince(then) {
var now = new Date(), obj = {};
obj.milliseconds = now.getUTCMilliseconds() - then.getUTCMilliseconds();
obj.seconds = now.getUTCSeconds() - then.getUTCSeconds();
obj.minutes = now.getUTCMinutes() - then.getUTCMinutes();
obj.hours = now.getUTCHours() - then.getUTCHours();
obj.days = now.getUTCDate() - then.getUTCDate();
obj.months = now.getUTCMonth() - then.getUTCMonth();
obj.years = now.getUTCFullYear() - then.getUTCFullYear();
// fix negatives
if (obj.milliseconds < 0) --obj.seconds, obj.milliseconds = (obj.milliseconds + 1000) % 1000;
if (obj.seconds < 0) --obj.minutes, obj.seconds = (obj.seconds + 60) % 60;
if (obj.minutes < 0) --obj.hours, obj.minutes = (obj.minutes + 60) % 60;
if (obj.hours < 0) --obj.days, obj.hours = (obj.hours + 24) % 24;
if (obj.days < 0) { // months have different lengths
--obj.months;
now.setUTCMonth(now.getUTCMonth() + 1);
now.setUTCDate(0);
obj.days = (obj.days + now.getUTCDate()) % now.getUTCDate();
}
if (obj.months < 0) --obj.years, obj.months = (obj.months + 12) % 12;
return obj;
}
This is an alternative solution, but one could argue it doesn't add enough value to make it worth it:
import com.google.common.collect.Iterables;
...
Iterator<String> iter = Iterables.cycle(list).iterator();
if(iter.hasNext()) {
str = iter.next();
}
Calling hasNext() will reset the iterator cursor to the beginning if it's a the end.
You can run the SQL Profiler, and filter by CPU or Duration so that you're excluding all the "small stuff". Then it should be a lot easier to determine if you have a problem like a specific stored proc that is running much longer than it should (could be a missing index or something).
Two caveats:
But normally I start with the Activity Monitor or sp_who2.
In a maven project create a file src/main/resources/application.yml
with the following content:
spring.profiles: integration
# use local or embedded mongodb at localhost:27017
---
spring.profiles: production
spring.data.mongodb.uri: mongodb://<user>:<passwd>@<host>:<port>/<dbname>
Spring Boot will automatically use this file to configure your application. Then you can start your spring boot application either with the integration profile (and use your local MongoDB)
java -jar -Dspring.profiles.active=integration your-app.jar
or with the production profile (and use your production MongoDB)
java -jar -Dspring.profiles.active=production your-app.jar
In your example parts of your passed-in URL are not URL encoded (for example the colon should be %3A, the forward slashes should be %2F). It looks like you have encoded the parameters to your parameter URL, but not the parameter URL itself. Try encoding it as well. You can use encodeURIComponent
.
You might want to start with scapy.
This is not my prefered way to do this, cause of massive CPU consumption.
If that is actually your working code, then just keep it like that. Checking a boolean once a second causes NO measurable CPU load. None whatsoever.
The real problem is that the thread that checks the value may not see a change that has happened for an arbitrarily long time due to caching. To ensure that the value is always synchronized between threads, you need to put the volatile keyword in the variable definition, i.e.
private volatile boolean value;
Note that putting the access in a synchronized
block, such as when using the notification-based solution described in other answers, will have the same effect.
Yes, it is a non-type parameter. You can have several kinds of template parameters
What you have there is of the last kind. It's a compile time constant (so-called constant expression) and is of type integer or enumeration. After looking it up in the standard, i had to move class templates up into the types section - even though templates are not types. But they are called type-parameters for the purpose of describing those kinds nonetheless. You can have pointers (and also member pointers) and references to objects/functions that have external linkage (those that can be linked to from other object files and whose address is unique in the entire program). Examples:
Template type parameter:
template<typename T>
struct Container {
T t;
};
// pass type "long" as argument.
Container<long> test;
Template integer parameter:
template<unsigned int S>
struct Vector {
unsigned char bytes[S];
};
// pass 3 as argument.
Vector<3> test;
Template pointer parameter (passing a pointer to a function)
template<void (*F)()>
struct FunctionWrapper {
static void call_it() { F(); }
};
// pass address of function do_it as argument.
void do_it() { }
FunctionWrapper<&do_it> test;
Template reference parameter (passing an integer)
template<int &A>
struct SillyExample {
static void do_it() { A = 10; }
};
// pass flag as argument
int flag;
SillyExample<flag> test;
Template template parameter.
template<template<typename T> class AllocatePolicy>
struct Pool {
void allocate(size_t n) {
int *p = AllocatePolicy<int>::allocate(n);
}
};
// pass the template "allocator" as argument.
template<typename T>
struct allocator { static T * allocate(size_t n) { return 0; } };
Pool<allocator> test;
A template without any parameters is not possible. But a template without any explicit argument is possible - it has default arguments:
template<unsigned int SIZE = 3>
struct Vector {
unsigned char buffer[SIZE];
};
Vector<> test;
Syntactically, template<>
is reserved to mark an explicit template specialization, instead of a template without parameters:
template<>
struct Vector<3> {
// alternative definition for SIZE == 3
};
I like google gson library.
When you don't know structure of json. You can use
JsonElement root = new JsonParser().parse(jsonString);
and then you can work with json. e.g. how to get "value1" from your gson:
String value1 = root.getAsJsonObject().get("data").getAsJsonObject().get("field1").getAsString();
In Preferences, select Python Interpreter
Under Python Interpreter, change from "Default" to "Use the following Python interpreter"
The path there should be the default Python executable. Find your Python 2.7 executable and use that.
Here you go, create a .bat file with the following in it :
@echo off
REM Creating a Newline variable (the two blank lines are required!)
set NLM=^
set NL=^^^%NLM%%NLM%^%NLM%%NLM%
REM Example Usage:
echo There should be a newline%NL%inserted here.
echo.
pause
You should see output like the following:
There should be a newline
inserted here.
Press any key to continue . . .
You only need the code between the REM statements, obviously.
If you don't want to use apache, you can use Java8:
byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw==");
System.out.println(new String(decodedBytes) + "\n");
To delete a job which has not yet run, you need the atrm
command. You can use atq
command to get its number in the at list.
To kill a job which has already started to run, you'll need to grep for it using:
ps -eaf | grep <command name>
and then use kill
to stop it.
A quicker way to do this on most systems is:
pkill <command name>
You can truncate the date
SELECT *
FROM Table1
WHERE trunc(field1) = to_Date('2012-01-01','YYY-MM-DD')
Look at the SQL Fiddle for more examples.
My code worked fine on all machines but only on this one started giving problem (which used to work find I guess). Used echo "document_root" path to debug and also looked closely at the error, found this
Warning: include(D:/MyProjects/testproject//functions/connections.php): failed to open stream:
You can easily see where the problems are. The problems are // before functions
$document_root = $_SERVER['DOCUMENT_ROOT'];
echo "root: $document_root";
include($document_root.'/functions/connections.php');
So simply remove the lading / from include and it should work fine. What is interesting is this behaviors is different on different versions. I run the same code on Laptop, Macbook Pro and this PC, all worked fine untill. Hope this helps someone.
Running ALTER COLUMN
without mentioning attribute NOT NULL
will result in the column being changed to nullable, if it is already not. Therefore, you need to first check if the column is nullable and if not, specify attribute NOT NULL
. Alternatively, you can use the following statement which checks the nullability of column beforehand and runs the command with the right attribute.
IF COLUMNPROPERTY(OBJECT_ID('Employee', 'U'), 'Salary', 'AllowsNull')=0
ALTER TABLE [Employee]
ALTER COLUMN [Salary] NUMERIC(22,5) NOT NULL
ELSE
ALTER TABLE [Employee]
ALTER COLUMN [Salary] NUMERIC(22,5) NULL
What a pity I did not see the question before - I've wrote library shell-framework which contains among others the maps(Associative arrays). The last version of it can be found here.
Example:
#!/bin/bash
#include map library
shF_PATH_TO_LIB="/usr/lib/shell-framework"
source "${shF_PATH_TO_LIB}/map"
#simple example get/put
putMapValue "mapName" "mapKey1" "map Value 2"
echo "mapName[mapKey1]: $(getMapValue "mapName" "mapKey1")"
#redefine old value to new
putMapValue "mapName" "mapKey1" "map Value 1"
echo "after change mapName[mapKey1]: $(getMapValue "mapName" "mapKey1")"
#add two new pairs key/values and print all keys
putMapValue "mapName" "mapKey2" "map Value 2"
putMapValue "mapName" "mapKey3" "map Value 3"
echo -e "mapName keys are \n$(getMapKeys "mapName")"
#create new map
putMapValue "subMapName" "subMapKey1" "sub map Value 1"
putMapValue "subMapName" "subMapKey2" "sub map Value 2"
#and put it in mapName under key "mapKey4"
putMapValue "mapName" "mapKey4" "subMapName"
#check if under two key were placed maps
echo "is map mapName[mapKey3]? - $(if isMap "$(getMapValue "mapName" "mapKey3")" ; then echo Yes; else echo No; fi)"
echo "is map mapName[mapKey4]? - $(if isMap "$(getMapValue "mapName" "mapKey4")" ; then echo Yes; else echo No; fi)"
#print map with sub maps
printf "%s\n" "$(mapToString "mapName")"
You could also group functions in one main file together with the main function looking like this:
function [varargout] = main( subfun, varargin )
[varargout{1:nargout}] = feval( subfun, varargin{:} );
% paste your subfunctions below ....
function str=subfun1
str='hello'
Then calling subfun1 would look like this: str=main('subfun1')
Easy.(Using Vanilla JS)
let days=30;
this.maxDateTime = new Date(Date.now() - days * 24 * 60 * 60 * 1000);
ISOFormat ?
let days=30;
this.maxDateTime = new Date(Date.now() - days * 24 * 60 * 60 * 1000).toISOString();
Perhaps what you're looking for is the SVG element's pointer-events property, which you can read about at the SVG w3C working group docs.
You can use CSS to set what happens to the SVG element when it is clicked, etc.
You just make div
s like this:
<div style="width:100px; height: 100px; border:1px solid; overflow:hidden; ">
<br/>
<div style="position:inherit; width: 200px; height:200px; background:yellow;">
<br/>
<div style="position:absolute; width: 500px; height:50px; background:Pink; z-index: 99;">
<br/>
</div>
</div>
</div>
I hope this code will help you :)
Try this:
keys=pygame.key.get_pressed()
if keys[K_LEFT]:
if count == 10:
location-=1
count=0
else:
count +=1
if location==-1:
location=0
if keys[K_RIGHT]:
if count == 10:
location+=1
count=0
else:
count +=1
if location==5:
location=4
This will mean you only move 1/10 of the time. If it still moves to fast you could try increasing the value you set "count" too.
If you are using MAMP Pro on Mac OS X it's done via the MAMP client by unchecking Activate Xdebug under the PHP tab:
You cannot add style to an SVG <g>
element. Its only purpose is to group children. That means, too, that style attributes you give to it are given down to its children, so a fill="green"
on the <g>
means an automatic fill="green"
on its child <rect>
(as long as it has no own fill
specification).
Your only option is to add a new <rect>
to the SVG and place it accordingly to match the <g>
children's dimensions.
The uuid module provides immutable UUID objects (the UUID class) and the functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122.
If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer’s network address. uuid4() creates a random UUID.

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.
Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.
As a guess, I would try using this:
Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate
If you negate an array, the lowest elements become the highest elements and vice-versa. Therefore, the indices of the n
highest elements are:
(-avgDists).argsort()[:n]
Another way to reason about this, as mentioned in the comments, is to observe that the big elements are coming last in the argsort. So, you can read from the tail of the argsort to find the n
highest elements:
avgDists.argsort()[::-1][:n]
Both methods are O(n log n) in time complexity, because the argsort
call is the dominant term here. But the second approach has a nice advantage: it replaces an O(n) negation of the array with an O(1) slice. If you're working with small arrays inside loops then you may get some performance gains from avoiding that negation, and if you're working with huge arrays then you can save on memory usage because the negation creates a copy of the entire array.
Note that these methods do not always give equivalent results: if a stable sort implementation is requested to argsort
, e.g. by passing the keyword argument kind='mergesort'
, then the first strategy will preserve the sorting stability, but the second strategy will break stability (i.e. the positions of equal items will get reversed).
Example timings:
Using a small array of 100 floats and a length 30 tail, the view method was about 15% faster
>>> avgDists = np.random.rand(100)
>>> n = 30
>>> timeit (-avgDists).argsort()[:n]
1.93 µs ± 6.68 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
>>> timeit avgDists.argsort()[::-1][:n]
1.64 µs ± 3.39 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
>>> timeit avgDists.argsort()[-n:][::-1]
1.64 µs ± 3.66 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
For larger arrays, the argsort is dominant and there is no significant timing difference
>>> avgDists = np.random.rand(1000)
>>> n = 300
>>> timeit (-avgDists).argsort()[:n]
21.9 µs ± 51.2 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
>>> timeit avgDists.argsort()[::-1][:n]
21.7 µs ± 33.3 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
>>> timeit avgDists.argsort()[-n:][::-1]
21.9 µs ± 37.1 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
Please note that the comment from nedim below is incorrect. Whether to truncate before or after reversing makes no difference in efficiency, since both of these operations are only striding a view of the array differently and not actually copying data.
Simply remove the line that rotates it one degree at a time and calls the script forever.
// Animate rotation with a recursive call
setTimeout(function() { rotate(++degree); },65);
Then pass the desired value into the function... in this example 45
for 45 degrees.
$(function() {
var $elie = $("#bkgimg");
rotate(45);
function rotate(degree) {
// For webkit browsers: e.g. Chrome
$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
// For Mozilla browser: e.g. Firefox
$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
}
});
Change .css()
to .animate()
in order to animate the rotation with jQuery. We also need to add a duration for the animation, 5000 for 5 seconds. And updating your original function to remove some redundancy and support more browsers...
$(function() {
var $elie = $("#bkgimg");
rotate(45);
function rotate(degree) {
$elie.animate({
'-webkit-transform': 'rotate(' + degree + 'deg)',
'-moz-transform': 'rotate(' + degree + 'deg)',
'-ms-transform': 'rotate(' + degree + 'deg)',
'-o-transform': 'rotate(' + degree + 'deg)',
'transform': 'rotate(' + degree + 'deg)',
'zoom': 1
}, 5000);
}
});
EDIT: The standard jQuery CSS animation code above is not working because apparently, jQuery .animate()
does not yet support the CSS3 transforms
.
This jQuery plugin is supposed to animate the rotation:
You can do it without having to create a real Hibernate mapping. Try this:
SELECT * FROM Employee e, Team t WHERE e.Id_team=t.Id_team
The field nbytes will give you the size in bytes of all the elements of the array in a numpy.array
:
size_in_bytes = my_numpy_array.nbytes
Notice that this does not measures "non-element attributes of the array object" so the actual size in bytes can be a few bytes larger than this.
JavaScript is a client-side language and your MySQL database is going to be running on a server.
So you have to rename your file to index.php
for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.
(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)
So after you renamed your file, go to the very top, before <html>
or <!DOCTYPE html>
and type:
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {
/*Creating variables*/
$name = $_POST["name"];
$address = $_POST["address"];
$age = $_POST["age"];
$dbhost = "localhost"; /*most of the time it's localhost*/
$username = "yourusername";
$password = "yourpassword";
$dbname = "mydatabase";
$mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
$query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
mysqli_query($mysql, $query);
}
?>
<!DOCTYPE html>
<html>
<head>.......
....
<form method="post">
<input name="name" type="text"/>
<input name="address" type="text"/>
<input name="age" type="text"/>
</form>

I've just had an email from a github.com admin stating the following: "We normally advise people to use the HTTPS URL unless they have a specific reason to be using the SSH protocol. HTTPS is secure and easier to set up, so we default to that when a new repository is created."
The password prompt does indeed accept the normal github.com login details. A tutorial on how to set up password caching can be found here. I followed the steps in the tutorial, and it worked for me.
The input in the markup is missing "type"
, the input (text I assume) has the attribute name="name"
and ID="cname"
, the provided code by Ayo calls the input named "cname"* where it should be "name".

7.2.1.1 The assert macro
Synopsis
1.
#include <assert.h> void assert(scalar expression);
Description
2 The assert macro puts diagnostic tests into programs; it expands to a void expression. When it is executed, if expression (which shall have a scalar type) is false (that is, compares equal to 0), the assert macro writes information about the particular call that failed (including the text of the argument, the name of the source file, the source line number, and the name of the enclosing function — the latter are respectively the values of the preprocessing macros
__FILE__
and__LINE__
and of the identifier__func__
) on the standard error stream in an implementation-defined format. 165) It then calls the abort function.Returns
3 The assert macro returns no value.

Edit 2018: This answer is pretty old and it uses checks for old browsers that are not necessary anymore, as the clientX
and clientY
properties work in all current browsers. You might want to check out Patriques Answer for a simpler, more recent solution.
Original Answer:
As described in an article i found back then but exists no longer:
var x;
var y;
if (e.pageX || e.pageY) {
x = e.pageX;
y = e.pageY;
}
else {
x = e.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
y = e.clientY + document.body.scrollTop + document.documentElement.scrollTop;
}
x -= gCanvasElement.offsetLeft;
y -= gCanvasElement.offsetTop;
Worked perfectly fine for me.
The Visual Studio Build tools are a different download than the IDE. They appear to be a pretty small subset, and they're called Build Tools for Visual Studio 2019 (download).
You can use the GUI to do the installation, or you can script the installation of msbuild:
vs_buildtools.exe --add Microsoft.VisualStudio.Workload.MSBuildTools --quiet
Microsoft.VisualStudio.Workload.MSBuildTools is a "wrapper" ID for the three subcomponents you need:
You can find documentation about the other available CLI switches here.
The build tools installation is much quicker than the full IDE. In my test, it took 5-10 seconds. With --quiet
there is no progress indicator other than a brief cursor change. If the installation was successful, you should be able to see the build tools in %programfiles(x86)%\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin
.
If you don't see them there, try running without --quiet
to see any error messages that may occur during installation.
Array object iteration, using jQuery, (use the second parameter to print the string).
$.each(array, function(index, item) {
console.log(index, item);
});
You can use SQLite's function creation routines (PHP manual):
$db_obj->sqliteCreateFunction('Encrypt', 'MyEncryptFunction', 2);
$db_obj->sqliteCreateFunction('Decrypt', 'MyDecryptFunction', 2);
When inserting data, you can use the encryption function directly and INSERT the encrypted data or you can use the custom function and pass unencrypted data:
$insert_obj = $db_obj->prepare('INSERT INTO table (Clear, Encrypted) ' .
'VALUES (:clear, Encrypt(:data, "' . $passwordhash_str . '"))');
When retrieving data, you can also use SQL search functionality:
$select_obj = $db_obj->prepare('SELECT Clear, ' .
'Decrypt(Encrypted, "' . $passwordhash_str . '") AS PlainText FROM table ' .
'WHERE PlainText LIKE :searchterm');
There are also some properties you can set to force a control to fill its available space when it would otherwise not do so. For example, you can say:
HorizontalContentAlignment="Stretch"
... to force the contents of a control to stretch horizontally. Or you can say:
HorizontalAlignment="Stretch"
... to force the control itself to stretch horizontally to fill its parent.
You could use a std::stringstream. You can stream anything into it:
std::stringstream stream;
stream << 5.7;
stream << foo.bar;
std::string s = stream.str();
That should be a quite general approach. (Works only for C++, but you asked the question for this language too.)
apt-get install python-dev
...solved the problem for me.
I also like using qdapTools::lookup
or shorthand binary operator %l%
. It works identically to an Excel vlookup, but it accepts name arguments opposed to column numbers
## Replicate Ben's data:
hous <- structure(list(HouseType = c("Semi", "Single", "Row", "Single",
"Apartment", "Apartment", "Row"), HouseTypeNo = c(1L, 2L, 3L,
2L, 4L, 4L, 3L)), .Names = c("HouseType", "HouseTypeNo"),
class = "data.frame", row.names = c(NA, -7L))
largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType),
1000, replace = TRUE)), stringsAsFactors = FALSE)
## It's this simple:
library(qdapTools)
largetable[, 1] %l% hous
You don't need to use sed
to do a substitution when in actual fact, you just want to insert a tab in front of the line. Substitution for this case is an expensive operation as compared to just printing it out, especially when you are working with big files. Its easier to read too as its not regex.
eg using awk
awk '{print "\t"$0}' $filename > temp && mv temp $filename
Regex.Replace
does not modify its first argument (recall that strings are immutable in .NET) so the call
Regex.Replace(LastName, @"\s+", "");
leaves the LastName
string unchanged. You need to call it like this:
LastName = Regex.Replace(LastName, @"\s+", "");
All three of your regular expressions would have worked. However, the first regex would remove all plus characters as well, which I imagine would be unintentional.
AngularJs has "Services" and "Factories" just for problems like yours.These are used to have something global between Controllers, Directives, Other Services or any other angularjs components..You can defined functions, store data, make calculate functions or whatever you want inside Services and use them in AngularJs Components as Global.like
angular.module('MyModule', [...])
.service('MyService', ['$http', function($http){
return {
users: [...],
getUserFriends: function(userId){
return $http({
method: 'GET',
url: '/api/user/friends/' + userId
});
}
....
}
}])

Whilst agreeing with Douwe Maan and Erik's answers, there are a couple of other things here that you may find useful.
Firstly, within your head tags, you can reference a separate JavaScript file, which is then reusable:
<script language="JavaScript" src="/common/common.js"></script>
where common.js is your reusable function file in a top-level directory called common.
Secondly, you can delay the operation of a script using setTimeout, e.g.:
setTimeout(someFunction, 5000);
The second argument is in milliseconds. I mention this, because you appear to be trying to delay something in your original code snippet.
Looks like the path you gave doesn't have any bootstrap files in them.

This program counts the number of all substrings even if they are overlapped without the use of regex. But this is a naive implementation and for better results in worst case it is advised to go through either Suffix Tree, KMP and other string matching data structures and algorithms.
$Group

.
Change $Group.StartsWith("S_G_")
to $Group.samaccountname.StartsWith("S_G_")
.
read
does not export the variable (which is a good thing most of the time). Here's an alternative which can be exported in one command, can preserve or discard linefeeds, and allows mixing of quoting-styles as needed. Works for bash and zsh.
oneLine=$(printf %s \
a \
" b " \
$'\tc\t' \
'd ' \
)
multiLine=$(printf '%s\n' \
a \
" b " \
$'\tc\t' \
'd ' \
)
I admit the need for quoting makes this ugly for SQL, but it answers the (more generally expressed) question in the title.
I use it like this
export LS_COLORS=$(printf %s \
':*rc=36:*.ini=36:*.inf=36:*.cfg=36:*~=33:*.bak=33:*$=33' \

From managed code you have access to instances of the Thread
type for each managed thread. Thread
encapsulates the concept of an OS thread and as of the current CLR there's a one-to-one correspondance with managed threads and OS threads. However, this is an implementation detail, that may change in the future.
The ID displayed by Visual Studio is actually the OS thread ID. This is not the same as the managed thread ID as suggested by several replies.
The Thread
type does include a private IntPtr member field called DONT_USE_InternalThread
, which points to the underlying OS structure. However, as this is really an implementation detail it is not advisable to pursue this IMO. And the name sort of indicates that you shouldn't rely on this.
Swift 3:

<item name="android:windowBackground">@android:color/black</item>
</style>
</resources>
You could transform this dict a little to ensure that (as dicts aren't kept sorted internally), e.g.
pprint([(key, mydict[key]) for key in sorted(mydict.keys())])
@dev-nish Your code works with little tweaks in them. make the
const navigationExtras: NavigationExtras = {
state: {
transd: 'TRANS001',
workQueue: false,
services: 10,

}
};
into
let navigationExtras: NavigationExtras = {
state: {
transd: '',

then if you want to specifically sent a type of data, for example, JSON as a result of a form fill you can send the data in the same way as explained before.
function prettyJSON(obj) {
console.log(JSON.stringify(obj, null, 2));
}
// obj -> value to convert to a JSON string
// null -> (do nothing)
// 2 -> 2 spaces per indent level
Yeah, it's pretty simple:
input[type="submit"]{
background: #fff;
border: 1px solid #000;
text-shadow: 1px 1px 1px #000;
}
I recommend giving it an ID or a class so that you can target it more easily.
You should add the path where ng.cmd located. By default, it should be located on C:\Users\user\AppData\Roaming\npm

For some reason John Rees' answer sometimes did not work in my case. But it led me in the following direction. First I try to delete the directory recursively with the buggy -recurse option. Afterwards I descend into every subdir that's left and delete all files.
function Remove-Tree($Path)
{
Remove-Item $Path -force -Recurse -ErrorAction silentlycontinue
if (Test-Path "$Path\" -ErrorAction silentlycontinue)
{
$folders = Get-ChildItem -Path $Path –Directory -Force
ForEach ($folder in $folders)
{
Remove-Tree $folder.FullName
}
$files = Get-ChildItem -Path $Path -File -Force
ForEach ($file in $files)
{
Remove-Item $file.FullName -force
}
if (Test-Path "$Path\" -ErrorAction silentlycontinue)
{
Remove-Item $Path -force
}
}
}
If you want a management option, try the envs npm package. It returns environment values if they are set. Otherwise, you can specify a default value that is stored in a global defaults object variable if it is not in your environment.
Using .env ("dot ee-en-vee") or environment files is good for many reasons. Individuals may manage their own configs. You can deploy different environments (dev, stage, prod) to cloud services with their own environment settings. And you can set sensible defaults.
Inside your .env
file each line is an entry, like this example:
NODE_ENV=development
API_URL=http://api.domain.com
TRANSLATION_API_URL=/translations/
GA_UA=987654321-0
NEW_RELIC_KEY=hi-mom
SOME_TOKEN=asdfasdfasdf
SOME_OTHER_TOKEN=zxcvzxcvzxcv
You should not include the .env
in your version control repository (add it to your .gitignore
file).
To get variables from the .env
file into your environment, you can use a bash script to do the equivalent of export NODE_ENV=development
right before you start your application.
#!/bin/bash
while read line; do export "$line";
done <source .env
Then this goes in your application javascript:
var envs = require('envs');
// If NODE_ENV is not set,
// then this application will assume it's prod by default.
app.set('environment', envs('NODE_ENV', 'production'));
// Usage examples:
app.set('ga_account', envs('GA_UA'));
app.set('nr_browser_key', envs('NEW_RELIC_BROWSER_KEY'));
app.set('other', envs('SOME_OTHER_TOKEN));
You need to add a name
attribute to your dropdown list, then you need to add a required
attribute, and then you can reference the error using myForm.[input name].$error.required
:
HTML:
<form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
<input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
<select name="service_id" class="Sitedropdown" style="width: 220px;"
ng-model="ServiceID"
ng-options="service.ServiceID as service.ServiceName for service in services"
required>
<option value="">Select Service</option>
</select>
<span ng-show="myForm.service_id.$error.required">Select service</span>
</form>
Controller:
function Ctrl($scope) {
$scope.services = [
{ServiceID: 1, ServiceName: 'Service1'},
{ServiceID: 2, ServiceName: 'Service2'},
{ServiceID: 3, ServiceName: 'Service3'}
];
$scope.save = function(myForm) {
console.log('Selected Value: '+ myForm.service_id.$modelValue);
alert('Data Saved! without validate');
};
}
Here's a working plunker.
You don't even need doubles for this. Just multiply by 100 first and then divide. Otherwise the result would be less than 1 and get truncated to zero, as you saw.
edit: or if overflow is likely, if it would overflow (ie the dividend is bigger than 922337203685477581), divide the divisor by 100 first.
This is the current solution (Dec 2014) and works quite well. It features

This makes me wonder, when is it advisable to use the EntityManager.getReference() method instead of the EntityManager.find() method?
EntityManager.getReference()
is really an error prone method and there is really very few cases where a client code needs to use it.
Personally, I never needed to use it.
I disagree with the accepted answer and particularly :
If i call find method, JPA provider, behind the scenes, will call
SELECT NAME, AGE FROM PERSON WHERE PERSON_ID = ? UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?
If i call getReference method, JPA provider, behind the scenes, will call
UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?
It is not the behavior that I get with Hibernate 5 and the javadoc of getReference()
doesn't say such a thing :
Get an instance, whose state may be lazily fetched. If the requested instance does not exist in the database, the EntityNotFoundException is thrown when the instance state is first accessed. (The persistence provider runtime is permitted to throw the EntityNotFoundException when getReference is called.) The application should not expect that the instance state will be available upon detachment, unless it was accessed by the application while the entity manager was open.
EntityManager.getReference()
spares a query to retrieve the entity in two cases :
1) if the entity is stored in the Persistence context, that is
the first level cache.
And this behavior is not specific to EntityManager.getReference()
,
EntityManager.find()
will also spare a query to retrieve the entity if the entity is stored in the Persistence context.
You can check the first point with any example.
You can also rely on the actual Hibernate implementation.
Indeed, EntityManager.getReference()
relies on the createProxyIfNecessary()
method of the org.hibernate.event.internal.DefaultLoadEventListener
class to load the entity.
Here is its implementation :
private Object createProxyIfNecessary(
final LoadEvent event,
final EntityPersister persister,
final EntityKey keyToLoad,
final LoadEventListener.LoadType options,
final PersistenceContext persistenceContext) {
Object existing = persistenceContext.getEntity( keyToLoad );
if ( existing != null ) {
// return existing object or initialized proxy (unless deleted)
if ( traceEnabled ) {
LOG.trace( "Entity found in session cache" );
}
if ( options.isCheckDeleted() ) {
EntityEntry entry = persistenceContext.getEntry( existing );
Status status = entry.getStatus();
if ( status == Status.DELETED || status == Status.GONE ) {
return null;
}
}
return existing;
}
if ( traceEnabled ) {
LOG.trace( "Creating new proxy for entity" );
}
// return new uninitialized proxy
Object proxy = persister.createProxy( event.getEntityId(), event.getSession() );
persistenceContext.getBatchFetchQueue().addBatchLoadableEntityKey( keyToLoad );
persistenceContext.addProxy( keyToLoad, proxy );
return proxy;
}
The interesting part is :
Object existing = persistenceContext.getEntity( keyToLoad );
2) If we don't effectively manipulate the entity, echoing to the lazily fetched of the javadoc.
Indeed, to ensure the effective loading of the entity, invoking a method on it is required.
So the gain would be related to a scenario where we want to load a entity without having the need to use it ? In the frame of applications, this need is really uncommon and in addition the getReference()
behavior is also very misleading if you read the next part.
In terms of overhead, getReference()
is not better than find()
as discussed in the previous point.
So why use the one or the other ?
Invoking getReference()
may return a lazily fetched entity.
Here, the lazy fetching doesn't refer to relationships of the entity but the entity itself.
It means that if we invoke getReference()
and then the Persistence context is closed, the entity may be never loaded and so the result is really unpredictable. For example if the proxy object is serialized, you could get a null
reference as serialized result or if a method is invoked on the proxy object, an exception such as LazyInitializationException
is thrown.
It means that the throw of EntityNotFoundException
that is the main reason to use getReference()
to handle an instance that does not exist in the database as an error situation may be never performed while the entity is not existing.
EntityManager.find()
doesn't have the ambition of throwing EntityNotFoundException
if the entity is not found. Its behavior is both simple and clear. You will never have surprise as it returns always a loaded entity or null
(if the entity is not found) but never an entity under the shape of a proxy that may not be effectively loaded.
So EntityManager.find()
should be favored in the very most of cases.

I would like to add a word of warning when you are dealing with C++11-style allocator-aware containers. Swapping and assignment have subtly different semantics.
For concreteness, let us consider a container std::vector<T, A>
, where A
is some stateful allocator type, and we'll compare the following functions:
void fs(std::vector<T, A> & a, std::vector<T, A> & b)
{
a.swap(b);
b.clear(); // not important what you do with b
}
void fm(std::vector<T, A> & a, std::vector<T, A> & b)
{
a = std::move(b);
}
The purpose of both functions fs
and fm
is to give a
the state that b
had initially. However, there is a hidden question: What happens if a.get_allocator() != b.get_allocator()
? The answer is: It depends. Let's write AT = std::allocator_traits<A>
.
If AT::propagate_on_container_move_assignment
is std::true_type
, then fm
reassigns the allocator of a
with the value of b.get_allocator()
, otherwise it does not, and a
continues to use its original allocator. In that case, the data elements need to be swapped individually, since the storage of a
and b
is not compatible.
If AT::propagate_on_container_swap
is std::true_type
, then fs
swaps both data and allocators in the expected fashion.
If AT::propagate_on_container_swap
is std::false_type
, then we need a dynamic check.
a.get_allocator() == b.get_allocator()
, then the two containers use compatible storage, and swapping proceeds in the usual fashion.a.get_allocator() != b.get_allocator()
, the program has undefined behaviour (cf. [container.requirements.general/8].The upshot is that swapping has become a non-trivial operation in C++11 as soon as your container starts supporting stateful allocators. That's a somewhat "advanced use case", but it's not entirely unlikely, since move optimizations usually only become interesting once your class manages a resource, and memory is one of the most popular resources.
preg_replace('/[^a-zA-Z0-9\s]/', '',$string)
this is using for removing special character only rather than space between the strings.
On compileSdkVersoin 25, you could do this:
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:textColorSecondary">@color/your_color</item>
</style>
Besides the previous post instructions, I had to install the package Microsoft.jQuery.Unobtrusive.Ajax and add to the view the following line
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
Perl-style regular expressions (which the Java regex engine is more or less based upon) treat the following characters as special characters:
.^$|*+?()[{\
have special meaning outside of character classes,
]^-\
have special meaning inside of character classes ([...]
).
So you need to escape those (and only those) symbols depending on context (or, in the case of character classes, place them in positions where they can't be misinterpreted).
Needlessly escaping other characters may work, but some regex engines will treat this as syntax errors, for example \_
will cause an error in .NET.
Some others will lead to false results, for example \<
is interpreted as a literal <
in Perl, but in egrep
it means "word boundary".
So write -?\d+\.\d+\$
to match 1.50$
, -2.00$
etc. and [(){}[\]]
for a character class that matches all kinds of brackets/braces/parentheses.
If you need to transform a user input string into a regex-safe form, use java.util.regex.Pattern.quote
.
Further reading: Jan Goyvaert's blog RegexGuru on escaping metacharacters
instead of using
session.delete(object)
use
getHibernateTemplate().delete(object)
In both place for select
query and also for delete
use getHibernateTemplate()
In select
query you have to use DetachedCriteria
or Criteria
Example for select query
List<foo> fooList = new ArrayList<foo>();
DetachedCriteria queryCriteria = DetachedCriteria.forClass(foo.class);
queryCriteria.add(Restrictions.eq("Column_name",restriction));
fooList = getHibernateTemplate().findByCriteria(queryCriteria);
In hibernate avoid use of session,here I am not sure but problem occurs just because of session use
On unix and linux there is the file
command to guess file types. There's even a windows port.
From the man page:
File tests each argument in an attempt to classify it. There are three sets of tests, performed in this order: filesystem tests, magic number tests, and language tests. The first test that succeeds causes the file type to be printed.
You would need to run the file
command with the subprocess
module and then parse the results to figure out an extension.

You may want to mention which version of .NET you are using and your memory size.
You will be stuck to a 2G, for your application, limit though, so it depends on what is in your array.
If we're going to mention regular expressions, we might as well mention the switch

Note that the ceil(num * 100) / 100
trick will crash on some degenerate inputs, like 1e308. This may not come up often but I can tell you it just cost me a couple of days. To avoid this, "it would be nice if" ceil()
and floor()
took a decimal places argument, like round()
does... Meanwhile, anyone know a clean alternative that won't crash on inputs like this? I had some hopes for the decimal
package but it seems to die too:
>>> from math import ceil
>>> from decimal import Decimal, ROUND_DOWN, ROUND_UP
>>> num = 0.1111111111000
>>> ceil(num * 100) / 100
0.12
>>> float(Decimal(num).quantize(Decimal('.01'), rounding=ROUND_UP))
0.12
>>> num = 1e308
>>> ceil(num * 100) / 100
Traceback (most recent call last):
File "<string>", line 301, in runcode
File "<interactive input>", line 1, in <module>
OverflowError: cannot convert float infinity to integer
>>> float(Decimal(num).quantize(Decimal('.01'), rounding=ROUND_UP))
Traceback (most recent call last):
File "<string>", line 301, in runcode
File "<interactive input>", line 1, in <module>
decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>]
Of course one might say that crashing is the only sane behavior on such inputs, but I would argue that it's not the rounding but the multiplication that's causing the problem (that's why, eg, 1e306 doesn't crash), and a cleaner implementation of the round-up-nth-place fn would avoid the multiplication hack.
if you have a list a and then following statements
list<int>::iterator it; // declare an iterator
list<int>::const_iterator cit; // declare an const iterator
it=a.begin();
cit=a.begin();
you can change the contents of the element in the list using “it” but not “cit”, that is you can use “cit” for reading the contents not for updating the elements.
*it=*it+1;//returns no error
*cit=*cit+1;//this will return error
I know this post is ancient but, I found it useful.
It didn't resolve my issue of returning the record with a non empty text field so I thought I would add my solution.
This is the where clause that worked for me.
WHERE xyz LIKE CAST('% %' as text)
Using numpy, you can define the following:
import numpy as np
def cart2pol(x, y):
rho = np.sqrt(x**2 + y**2)
phi = np.arctan2(y, x)
return(rho, phi)
def pol2cart(rho, phi):
x = rho * np.cos(phi)
y = rho * np.sin(phi)
return(x, y)
In MSDN, Assembly.GetExecutingAssembly Method, is remark about method "getexecutingassembly", that for performance reasons, you should call this method only when you do not know at design time what assembly is currently executing.
The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly
property of a type found in the assembly.
The following example illustrates:
using System;
using System.Reflection;
public class Example
{
public static void Main()
{
Console.WriteLine("The version of the currently executing assembly is: {0}",
typeof(Example).Assembly.GetName().Version);
}
}
/* This example produces output similar to the following:
The version of the currently executing assembly is: 1.1.0.0
Of course this is very similar to the answer with helper class "public static class CoreAssembly", but, if you know at least one type of executing assembly, it isn't mandatory to create a helper class, and it saves your time.

You can simply use the SASS mixin to change the number of cards across in each breakpoint / grid tier.
.card-columns {
@include media-breakpoint-only(xl) {
column-count: 5;
}
@include media-breakpoint-only(lg) {
column-count: 4;
}
@include media-breakpoint-only(md) {
column-count: 3;
}
@include media-breakpoint-only(sm) {
column-count: 2;
}
}

Or, CSS only like this...
@media (min-width: 576px) {
.card-columns {
column-count: 2;
}
}
@media (min-width: 768px) {
.card-columns {
column-count: 3;
}
}
@media (min-width: 992px) {
.card-columns {
column-count: 4;
}
}
@media (min-width: 1200px) {
.card-columns {
column-count: 5;
}
}

The output of ps aux
looks like you did not start docker through systemd/systemctl.
It looks like you started it with:
sudo dockerd -H gridsim1103:2376
When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.
The correct way to start docker is to use systemd/systemctl:
systemctl enable docker
systemctl start docker
After this, docker should start on system start.
EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.
This seems a far easier method than those suggested elsewhere in this thread.
May also want to use "documentElement":
var elem = document.createElement("div");
elem.style = "width:100px;height:100px;position:relative;background:#FF0000;";
document.documentElement.appendChild(elem);
Using regex for string replacement is significantly slower than using a string replace.
As demonstrated on JSPerf, you can have different levels of efficiency for creating a regex, but all of them are significantly slower than a simple string replace. The regex is slower because:
Fixed-string matches don't have backtracking, compilation steps, ranges, character classes, or a host of other features that slow down the regular expression engine. There are certainly ways to optimize regex matches, but I think it's unlikely to beat indexing into a string in the common case.
For a simple test run on the JS perf page, I've documented some of the results:
<script>_x000D_
// Setup_x000D_
var startString = "xxxxxxxxxabcxxxxxxabcxx";_x000D_
var endStringRegEx = undefined;_x000D_
var endStringString = undefined;_x000D_
var endStringRegExNewStr = undefined;_x000D_
var endStringRegExNew = undefined;_x000D_
var endStringStoredRegEx = undefined; _x000D_
var re = new RegExp("abc", "g");_x000D_
</script>_x000D_

endStringRegEx = startString.replace(/abc/g, "def") // Regex_x000D_
endStringString = startString.replace("abc", "def", "g") // String_x000D_
endStringRegExNewStr = startString.replace(new RegExp("abc", "g"), "def"); // New Regex String_x000D_
endStringRegExNew = startString.replace(new RegExp(/abc/g), "def"); // New Regexp_x000D_
endStringStoredRegEx = startString.replace(re, "def") // saved regex_x000D_

The results for Chrome 68 are as follows:
String replace: 9,936,093 operations/sec
Saved regex: 5,725,506 operations/sec
Regex: 5,529,504 operations/sec
New Regex String: 3,571,180 operations/sec
New Regex: 3,224,919 operations/sec
From the sake of completeness of this answer (borrowing from the comments), it's worth mentioning that .replace
only replaces the first instance of the matched character. Its only possible to replace all instances with //g
. The performance trade off and code elegance could be argued to be worse if replacing multiple instances name.replace(' ', '_').replace(' ', '_').replace(' ', '_');
or worse while (name.includes(' ')) { name = name.replace(' ', '_') }
Following command will list down all the files having exact name "pattern" (for example) in current and its sub folders.
find ./ -name "pattern"
Use !=
or <>
. Both stands for not equal.
The comparison operators <>
and !=
are alternate spellings of the same operator. !=
is the preferred spelling; <>
is obsolescent. [Reference: Python language reference]
