Use JoinColumn
well i might be late on this but i would like to share something:
Given the input: System.out.println(isGreaterThanZero(-1));
public static boolean isGreaterThanZero(Integer value) {
return value == null?false:value.compareTo(0) > 0;
}
Returns false
public static boolean isGreaterThanZero(Integer value) {
return value == null?false:value.intValue() > 0;
}
Returns true So i think in yourcase 'compareTo' will be more accurate.
I got this working by installing the various plugins below.
Most of the time things just import by themselves as soon as I type the class name. Alternatively, a lightbulb appears that you can click on. Or you can push F1, and type "import..." and there are various options there too. I kinda use all of them. Also F1 Implement for implementing an interface is helpful, but doesn't always work.

The simpliest solution (in case you are using fastcgi+nignx) is what itgorilla commented:
Thank you for this great question. My fastcgi was not passing the REMOTE_ADDR meta key. I added the line below in the nginx.conf and fixed the problem: fastcgi_param REMOTE_ADDR $remote_addr; – itgorilla
Ps: I added this answer just to make his solution more visible.
If the body of the arrow function is wrapped in curly braces, it is not implicitly returned. Wrap the object in parentheses. It would look something like this.
p => ({ foo: 'bar' })
By wrapping the body in parens, the function will return { foo: 'bar }
.
Hopefully, that solves your problem. If not, I recently wrote an article about Arrow functions which covers it in more detail. I hope you find it useful. Javascript Arrow Functions
According to the Wordpress documentation, you should use wp_localize_script()
in your functions.php file. This will create a Javascript Object in the header, which will be available to your scripts at runtime.
See Codex
Example:
<?php wp_localize_script('mylib', 'WPURLS', array( 'siteurl' => get_option('siteurl') )); ?>
To access this variable within in Javascript, you would simply do:
<script type="text/javascript">
var url = WPURLS.siteurl;
</script>
I would suggest reading this url http://docs.angularjs.org/api/ngResource/service/$resource
and revaluate how you are calling your delete method of your resources.
ideally you would want to be calling the delete of the resource item itself and by not passing the id of the resource into a catch all delete method
however $http.delete accepts a config object that contains both url and data properties you could either craft the query string there or pass an object/string into the data
maybe something along these lines
$http.delete('/roles/'+roleid, {data: input});
You can set a default option for the column in the migration
....
add_column :status, :string, :default => "P"
....
OR
You can use a callback, before_save
class Task < ActiveRecord::Base
before_save :default_values
def default_values
self.status ||= 'P' # note self.status = 'P' if self.status.nil? might be safer (per @frontendbeauty)
end
end
That's Oracle specific notation for an OUTER JOIN, because the ANSI-89 format (using a comma in the FROM clause to separate table references) didn't standardize OUTER joins.
The query would be re-written in ANSI-92 syntax as:
SELECT ...
FROM a
LEFT JOIN b ON b.id = a.id
This link is pretty good at explaining the difference between JOINs.
It should also be noted that even though the (+)
works, Oracle recommends not using it:
Oracle recommends that you use the
FROM
clauseOUTER JOIN
syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator(+)
are subject to the following rules and restrictions, which do not apply to theFROM
clauseOUTER JOIN
syntax:
I don't know if the answer will be late, but I have used this form.

For those of you developing regular websites or PWAs (Progressive Web Apps) for mobile devices and/or laptops/monitors with touch screens, then you have landed here because you might be used to mouse events and are new to the sometimes painful experience of Touch events... yay!
There are just 3 rules:
mousemove
or touchmove

or touchstart
events.Needless to say, things are more complicated with touch
events because there can be more than one and they're more flexible (complicated) than mouse events. I'm only going to cover a single touch here. Yes, I'm being lazy, but it's the most common type of touch, so there.

To undo a github pull request with commits throughout that you do not want to delete, you have to run a:
git reset --hard --merge <commit hash>
with the commit hash being the commit PRIOR to merging the pull request. This will remove all commits from the pull request without influencing any commits within the history.
A good way to find this is to go to the now closed pull request and finding this field:
After you run the git reset
, run a:
git push origin --force <branch name>
This should revert the branch back before the pull request WITHOUT affecting any commits in the branch peppered into the commit history between commits from the pull request.
EDIT:
If you were to click the revert button on the pull request, this creates an additional commit on the branch. It DOES NOT uncommit or unmerge. This means that if you were to hit the revert button, you cannot open a new pull request to re-add all of this code.
Use the following to evaluate an expression (constant 0 evaluates to false).
#if 0
...
#endif
You should use the -m (mirror) flag, as that takes care to not mess with timestamps and to recurse indefinitely.
wget -m http://example.com/configs/.vim/
If you add the points mentioned by others in this thread, it would be:
wget -m -e robots=off --no-parent http://example.com/configs/.vim/
You need to add the original repository (the one that you forked) as a remote.
git remote add github (clone url for the orignal repository)
Then you need to bring in the changes to your local repository
git fetch github
Now you will have all the branches of the original repository in your local one. For example, the master branch will be github/master
. With these branches you can do what you will. Merge them into your branches etc
Ken, good question. I should be more explicit in the The Definitive Guide about the difference. "install" and "deploy" serve two different purposes in a build. "install" refers to the process of installing an artifact in your local repository. "deploy" refers to the process of deploying an artifact to a remote repository.
Example:
When I run a large multi-module project on a my machine, I'm going to usually run "mvn install". This is going to install all of the generated binary software artifacts (usually JARs) in my local repository. Then when I build individual modules in the build, Maven is going to retrieve the dependencies from the local repository.
When it comes time to deploy snapshots or releases, I'm going to run "mvn deploy". Running this is going to attempt to deploy the files to a remote repository or server. Usually I'm going to be deploying to a repository manager such as Nexus
It is true that running "deploy" is going to require some extra configuration, you are going to have to supply a distributionManagement section in your POM.
$('p:after').css('display','none');
Have a look at this for some common errors in setting the java heap. You've probably set the heap size to a larger value than your computer's physical memory.
You should avoid solving this problem by increasing the heap size. Instead, you should profile your application to see where you spend such a large amount of memory.
UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.
If your project uses Maven you can simply include UCanAccess via the following coordinates:
groupId: net.sf.ucanaccess
artifactId: ucanaccess
The following is an excerpt from pom.xml
, you may need to update the <version>
to get the most recent release:
<dependencies>
<dependency>
<groupId>net.sf.ucanaccess</groupId>
<artifactId>ucanaccess</artifactId>
<version>4.0.4</version>
</dependency>
</dependencies>
As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:
UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)
Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like
ucanaccess-4.0.1.jar
/lib/
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.1.6.jar
All you need to do is add all five (5) JARs to your project.
NOTE: Do not add
loader/ucanload.jar
to your build path if you are adding the other five (5) JAR files. TheUcanloadDriver
class is only used in special circumstances and requires a different setup. See the related answer here for details.
Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path...
. Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this
NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.
After adding all five (5) JAR files the "Libraries" folder should look something like this:
IntelliJ IDEA: Choose File > Project Structure...
from the main menu. In the "Libraries" pane click the "Add" (+
) button and add the five (5) JAR files. Once that is done the project should look something like this:
Now "U Can Access" data in .accdb and .mdb files using code like this
// assumes...
// import java.sql.*;
Connection conn=DriverManager.getConnection(
"jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
System.out.println(rs.getString(1));
}
At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.
\s
matches whitespace (spaces, tabs and new lines). \S
is negated \s
.
The options are the same as for the fopen function in the C standard library:
w
truncates the file, overwriting whatever was already there
a
appends to the file, adding onto whatever was already there
w+
opens for reading and writing, truncating the file but also allowing you to read back what's been written to the file
a+
opens for appending and reading, allowing you both to append to the file and also read its contents
You're using the ajax function incorrectly. Since it's synchronous it'll return the data inline like so:
var remote = $.ajax({
type: "GET",
url: remote_url,
async: false
}).responseText;
REPEAT
...
UNTIL cond
Is equivalent to
while True:
...
if cond:
break
getBadgeClasses() {
let classes = "badge m-2 ";
classes += (this.state.count === 0) ? "badge-warning" : "badge-primary";
return classes;
}
<span className={this.getBadgeClasses()}>Total Count</span>
Check out some of the answers to this question - I think it might apply to yours:
how to run click function after default behaviour of a element
I think you're running into an inconsistency in the browser implementation of the onclick
function. Some choose to toggle the checkbox before the event is fired and some after.
Below code might help you to copy the first level objects
let original = [{ a: 1 }, {b:1}]
const copy = [ ...original ].map(item=>({...item}))
so for below case, values remains intact
copy[0].a = 23
console.log(original[0].a) //logs 1 -- value didn't change voila :)
Fails for this case
let original = [{ a: {b:2} }, {b:1}]
const copy = [ ...original ].map(item=>({...item}))
copy[0].a.b = 23;
console.log(original[0].a) //logs 23 -- lost the original one :(
Final advice:
I would say go for lodash cloneDeep
API which helps you to copy the objects inside objects completely dereferencing from original one's. This can be installed as a separate module.
Refer documentation: https://github.com/lodash/lodash
Individual Package : https://www.npmjs.com/package/lodash.clonedeep
I modified indgar's solution to handle negative numbers and small numbers (including zero).
from math import log10, floor
def round_sig(x, sig=6, small_value=1.0e-9):
return round(x, sig - int(floor(log10(max(abs(x), abs(small_value))))) - 1)
You can try this:
/*iPad landscape oriented styles */
@media only screen and (device-width:768px)and (orientation:landscape){
.yourstyle{
}
}
/*iPad Portrait oriented styles */
@media only screen and (device-width:768px)and (orientation:portrait){
.yourstyle{
}
}
You can use the following "trick" to parse any valid URL. It takes advantage of the anchor element's special href-related property, hash
.
function getHashFromUrl(url){
return $("<a />").attr("href", url)[0].hash.replace(/^#/, "");
}
getHashFromUrl("www.example.com/task1/1.3.html#a_1"); // a_1
function getHashFromUrl(url){
var a = document.createElement("a");
a.href = url;
return a.hash.replace(/^#/, "");
};
getHashFromUrl("www.example.com/task1/1.3.html#a_1"); // a_1
This should do what you want:
sed 's/two.*/BLAH/'
$ echo " one two three five
> four two five five six
> six one two seven four" | sed 's/two.*/BLAH/'
one BLAH
four BLAH
six one BLAH
The $
is unnecessary because the .*
will finish at the end of the line anyways, and the g
at the end is unnecessary because your first match will be the first two
to the end of the line.
Here is something that might help. Use the root privileges. if you have .bin then simply add the execution permission to the bin file.
chmod a+x jdk*.bin
next step is to run the .bin file which is simply
./jdk*.bin in the location you want to install.
you are done.
You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder. You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.
Here is my technique I'd like to share. Works well so long as your clr property types are sql equivalent types eg. bool -> bit, long -> bigint, string -> nchar/char/varchar/nvarchar, decimal -> money

foreach (var prop in transaction.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))

The simple solution is to cast CLOB to BLOB and then request length of BLOB !
The problem is that Oracle doesn't have a function that cast CLOB to BLOB, but we can simply define a function to do that
create or replace
FUNCTION clob2blob (p_in clob) RETURN blob IS
v_blob blob;
v_desc_offset PLS_INTEGER := 1;
v_src_offset PLS_INTEGER := 1;
v_lang PLS_INTEGER := 0;
v_warning PLS_INTEGER := 0;
BEGIN
dbms_lob.createtemporary(v_blob,TRUE);
dbms_lob.converttoblob
( v_blob
, p_in
, dbms_lob.getlength(p_in)
, v_desc_offset
, v_src_offset
, dbms_lob.default_csid
, v_lang
, v_warning
);
RETURN v_blob;
END;
The SQL command to use to obtain number of bytes is
SELECT length(clob2blob(fieldname)) as nr_bytes
or
SELECT dbms_lob.getlength(clob2blob(fieldname)) as nr_bytes
I have tested this on Oracle 10g without using Unicode(UTF-8). But I think that this solution must be correct using Unicode(UTF-8) Oracle instance :-)
I want render thanks to Nashev that has posted a solution to convert clob to blob How convert CLOB to BLOB in Oracle? and to this post written in german (the code is in PL/SQL) 13ter.info.blog that give additionally a function to convert blob to clob !
Can somebody test the 2 commands in Unicode(UTF-8) CLOB so I'm sure that this works with Unicode ?

If you see the man page of logger:
$ man logger

NAME logger — a shell command interface to the syslog(3) system log module
SYNOPSIS logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]
DESCRIPTION Logger makes entries in the system log. It provides a shell command interface to the syslog(3) system log module.
It Clearly says that it will log to system log. If you want to log to file, you can use ">>" to redirect to log file.
Angular CLI: 8.3.1
when you have multiple module.ts
files inside a module, you need to specify for which module file you are generating component.
ng g c modulefolder/componentname --module=modulename.module
for e.g. i have shared module folder inside which i have shared.module.ts
and material.module.ts
like this
shared
> shared.module.ts
> material.module.ts
and i want to generate sidebar
component for shared.module.ts
then i will run following command
ng g c shared/sidebar --module=shared.module
if you want to export the component then run following command
ng g c shared/sidebar --module=shared.module --export
$("#container").delegate("span", "click", function (){
alert(11);
});
Here is the jQuery function I use:
function isExists(var elemId){
return jQuery('#'+elemId).length > 0;
}
This will return a boolean value. If element exists, it returns true.
If you want to select element by class name, just replace #
with .
You'll want to use os.walk
to collect filenames that match your criteria. For example:
import os
cfiles = []
for root, dirs, files in os.walk('src'):
for file in files:
if file.endswith('.c'):
cfiles.append(os.path.join(root, file))
A case where the dictionary values is a set. Like:
some_dict = {"1":{"a","b","c"},
"2":{"d","e","f"},
"3":{"g","h","i"}}
The inverse would like:
some_dict = {vi: k for k, v in some_dict.items() for vi in v}
The output is like this:
{'c': '1',
'b': '1',
'a': '1',
'f': '2',
'd': '2',
'e': '2',
'g': '3',
'h': '3',
'i': '3'}
EOF
is a constant in C. You are not checking the actual file for EOF. You need to do something like this
while(!feof(stdin))
Here is the documentation to feof. You can also check the return value of scanf. It returns the number of successfully converted items, or EOF
if it reaches the end of the file.
If you dont want to use any module for age calculation
var age = Math.floor((new Date() - new Date(date_of_birth)) / 1000 / 60 / 60 / 24 / 365.25)
Put it inside your <footer>
by all means, but the most fitting element is the small element.
The HTML5 spec for this says:
Small print typically features disclaimers, caveats, legal restrictions, or copyrights. Small print is also sometimes used for attribution, or for satisfying licensing requirements.
Do this with a file stream. When a std::ofstream
is closed, the file is created. I personally like the following code, because the OP only asks to create a file, not to write in it:
#include <fstream>
int main()
{
std::ofstream file { "Hello.txt" };
// Hello.txt has been created here
}
The temporary variable file
is destroyed right after its creation, so the stream is closed and thus the file is created.
I created a function to handle this situation, thought I would share it.
getDirectDecendent(elem, selector, all){
const tempID = randomString(10) //use your randomString function here.
elem.dataset.tempid = tempID;
let returnObj;
if(all)
returnObj = elem.parentElement.querySelectorAll(`[data-tempid="${tempID}"] > ${selector}`);
else
returnObj = elem.parentElement.querySelector(`[data-tempid="${tempID}"] > ${selector}`);
elem.dataset.tempid = '';
return returnObj;
}
In essence what you are doing is generating a random-string (randomString function here is an imported npm module, but you can make your own.) then using that random string to guarantee that you get the element you are expecting in the selector. Then you are free to use the >
after that.
The reason I am not using the id attribute is that the id attribute may already be used and I don't want to override that.
The trick is to add both max-height: 100%;
and max-width: 100%;
to .container img
. Example CSS:
.container {
width: 300px;
border: dashed blue 1px;
}
.container img {
max-height: 100%;
max-width: 100%;
}
In this way, you can vary the specified width of .container
in whatever way you want (200px or 10% for example), and the image will be no larger than its natural dimensions. (You could specify pixels instead of 100% if you didn't want to rely on the natural size of the image.)
Here's the whole fiddle: http://jsfiddle.net/KatieK/Su28P/1/
In Python 3 this is the default behavior, but if you aren't using that you can import division like so:
>>> from __future__ import division
>>> 144/314
0.4585987261146497
Alternatively you can cast one of the variables to a float when doing your division which will do the same thing

How about reversing the Collection backing the stream prior?
import java.util.Collections;
import java.util.List;
public void reverseTest(List<Integer> sampleCollection) {
Collections.reverse(sampleCollection); // remember this reverses the elements in the list, so if you want the original input collection to remain untouched clone it first.
sampleCollection.stream().forEach(item -> {
// you op here
});
}
If you are sending alphanumeric data try changing
'Content-Type': 'multipart/form-data'
to
'Content-Type': 'application/x-www-form-urlencoded'
If you are sending non-alphanumeric data try to remove 'Content-Type' at all.
If it still does not work, consider trying request-promise (at least to test whether it is really axios problem or not)
When your browser redirects the user to Google's oAuth page, are you passing as a parameter the redirect URI you want Google's server to return to with the token response? Setting a redirect URI in the console is not a way of telling Google where to go when a login attempt comes in, but rather it's a way of telling Google what the allowed redirect URIs are (so if someone else writes a web app with your client ID but a different redirect URI it will be disallowed); your web app should, when someone clicks the "login" button, send the browser to:
https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=http://localhost:8080/WEBAPP/youtube-callback.html&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload
(the callback URI passed as a parameter must be url-encoded, btw).
When Google's server gets authorization from the user, then, it'll redirect the browser to whatever you sent in as the redirect_uri
. It'll include in that request the token as a parameter, so your callback page can then validate the token, get an access token, and move on to the other parts of your app.
If you visit:
http://code.google.com/p/google-api-java-client/wiki/OAuth2#Authorization_Code_Flow
You can see better samples of the java client there, demonstrating that you have to override the getRedirectUri
method to specify your callback path so the default isn't used.
The redirect URIs are in the client_secrets.json
file for multiple reasons ... one big one is so that the oAuth flow can verify that the redirect your app specifies matches what your app allows.
If you visit https://developers.google.com/api-client-library/java/apis/youtube/v3 You can generate a sample application for yourself that's based directly off your app in the console, in which (again) the getRedirectUri method is overwritten to use your specific callbacks.
Local package is a annoying problem in go.
For some projects in our company we decide not use sub packages at all.
$ glide install
$ go get
$ go install
All work.
For some projects we use sub packages, and import local packages with full path:
import "xxxx.gitlab.xx/xxgroup/xxproject/xxsubpackage
But if we fork this project, then the subpackages still refer the original one.
There are a number of ways to look at a date difference, and more when comparing date/times. Here's what I use to get the difference between two dates formatted as "HH:MM:SS":
ElapsedTime AS
RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) / 3600 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 3600 / 60 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 60 AS VARCHAR(2)), 2)
I used this for a calculated column, but you could trivially rewrite it as a UDF or query calculation. Note that this logic rounds down fractional seconds; 00:00.00 to 00:00.999 is considered zero seconds, and displayed as "00:00:00".
If you anticipate that periods may be more than a few days long, this code switches to D:HH:MM:SS format when needed:
ElapsedTime AS
CASE WHEN DATEDIFF(S, StartDate, EndDate) >= 359999
THEN
CAST(DATEDIFF(S, StartDate, EndDate) / 86400 AS VARCHAR(7)) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 86400 / 3600 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 3600 / 60 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 60 AS VARCHAR(2)), 2)
ELSE
RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) / 3600 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 3600 / 60 AS VARCHAR(2)), 2) + ':'
+ RIGHT('0' + CAST(DATEDIFF(S, StartDate, EndDate) % 60 AS VARCHAR(2)), 2)
END
Another approach:
union IP {
unsigned int ip;
struct {
unsigned char d;
unsigned char c;
unsigned char b;
unsigned char a;
} ip2;
};
...
char ips[20];
IP ip;
ip.ip = 0xAABBCCDD;
sprintf(ips, "%x.%x.%x.%x", ip.ip2.a, ip.ip2.b, ip.ip2.c, ip.ip2.d);
printf("%s\n", ips);
Linux kernel 5.0 source comments
I knew that x86 specifics are under arch/x86
, and that syscall stuff goes under arch/x86/entry
. So a quick git grep rdi
in that directory leads me to arch/x86/entry/entry_64.S:
/*
* 64-bit SYSCALL instruction entry. Up to 6 arguments in registers.
*
* This is the only entry point used for 64-bit system calls. The
* hardware interface is reasonably well designed and the register to
* argument mapping Linux uses fits well with the registers that are
* available when SYSCALL is used.
*
* SYSCALL instructions can be found inlined in libc implementations as
* well as some other programs and libraries. There are also a handful
* of SYSCALL instructions in the vDSO used, for example, as a
* clock_gettimeofday fallback.
*
* 64-bit SYSCALL saves rip to rcx, clears rflags.RF, then saves rflags to r11,
* then loads new ss, cs, and rip from previously programmed MSRs.
* rflags gets masked by a value from another MSR (so CLD and CLAC
* are not needed). SYSCALL does not save anything on the stack
* and does not change rsp.
*
* Registers on entry:
* rax system call number
* rcx return address
* r11 saved rflags (note: r11 is callee-clobbered register in C ABI)
* rdi arg0
* rsi arg1
* rdx arg2
* r10 arg3 (needs to be moved to rcx to conform to C ABI)
* r8 arg4
* r9 arg5
* (note: r12-r15, rbp, rbx are callee-preserved in C ABI)
*
* Only called from user space.
*
* When user can change pt_regs->foo always force IRET. That is because
* it deals with uncanonical addresses better. SYSRET has trouble
* with them due to bugs in both AMD and Intel CPUs.
*/
and for 32-bit at arch/x86/entry/entry_32.S:
/*
* 32-bit SYSENTER entry.
*
* 32-bit system calls through the vDSO's __kernel_vsyscall enter here
* if X86_FEATURE_SEP is available. This is the preferred system call
* entry on 32-bit systems.
*
* The SYSENTER instruction, in principle, should *only* occur in the
* vDSO. In practice, a small number of Android devices were shipped
* with a copy of Bionic that inlined a SYSENTER instruction. This
* never happened in any of Google's Bionic versions -- it only happened
* in a narrow range of Intel-provided versions.
*
* SYSENTER loads SS, ESP, CS, and EIP from previously programmed MSRs.
* IF and VM in RFLAGS are cleared (IOW: interrupts are off).
* SYSENTER does not save anything on the stack,
* and does not save old EIP (!!!), ESP, or EFLAGS.
*
* To avoid losing track of EFLAGS.VM (and thus potentially corrupting
* user and/or vm86 state), we explicitly disable the SYSENTER
* instruction in vm86 mode by reprogramming the MSRs.

* edx arg3
* esi arg4

glibc 2.29 Linux x86_64 system call implementation
Now let's cheat by looking at a major libc implementations and see what they are doing.
What could be better than looking into glibc that I'm using right now as I write this answer? :-)
glibc 2.29 defines x86_64 syscalls at sysdeps/unix/sysv/linux/x86_64/sysdep.h
and that contains some interesting code, e.g.:
/* The Linux/x86-64 kernel expects the system call parameters in
registers according to the following table:
syscall number rax
arg 1 rdi
arg 2 rsi
arg 3 rdx
arg 4 r10
arg 5 r8
arg 6 r9
The Linux kernel uses and destroys internally these registers:
return address from
syscall rcx
eflags from syscall r11
Normal function call, including calls to the system call stub
functions in the libc, get the first six parameters passed in
registers and the seventh parameter and later on the stack. The
register use is as follows:
system call number in the DO_CALL macro
arg 1 rdi
arg 2 rsi
arg 3 rdx
arg 4 rcx
arg 5 r8
arg 6 r9
We have to take care that the stack is aligned to 16 bytes. When
called the stack is not aligned since the return address has just
been pushed.
Syscalls of more than 6 arguments are not supported. */
and:
/* Registers clobbered by syscall. */
# define REGISTERS_CLOBBERED_BY_SYSCALL "cc", "r11", "cx"
#undef internal_syscall6
#define internal_syscall6(number, err, arg1, arg2, arg3, arg4, arg5, arg6) \
({ \
unsigned long int resultvar; \
TYPEFY (arg6, __arg6) = ARGIFY (arg6); \
TYPEFY (arg5, __arg5) = ARGIFY (arg5); \
TYPEFY (arg4, __arg4) = ARGIFY (arg4); \
TYPEFY (arg3, __arg3) = ARGIFY (arg3); \
TYPEFY (arg2, __arg2) = ARGIFY (arg2); \
TYPEFY (arg1, __arg1) = ARGIFY (arg1); \
register TYPEFY (arg6, _a6) asm ("r9") = __arg6; \
register TYPEFY (arg5, _a5) asm ("r8") = __arg5; \
register TYPEFY (arg4, _a4) asm ("r10") = __arg4; \
register TYPEFY (arg3, _a3) asm ("rdx") = __arg3; \
register TYPEFY (arg2, _a2) asm ("rsi") = __arg2; \
register TYPEFY (arg1, _a1) asm ("rdi") = __arg1; \
asm volatile ( \
"syscall\n\t" \
: "=a" (resultvar) \
: "0" (number), "r" (_a1), "r" (_a2), "r" (_a3), "r" (_a4), \
"r" (_a5), "r" (_a6) \
: "memory", REGISTERS_CLOBBERED_BY_SYSCALL); \
(long int) resultvar; \
})
which I feel are pretty self explanatory. Note how this seems to have been designed to exactly match the calling convention of regular System V AMD64 ABI functions: https://en.wikipedia.org/wiki/X86_calling_conventions#List_of_x86_calling_conventions

Here's an example with register constraints: How to invoke a system call via syscall or sysenter in inline assembly?
aarch64
I've shown a minimal runnable userland example at: https://reverseengineering.stackexchange.com/questions/16917/arm64-syscalls-table/18834#18834 TODO grep kernel code here, should be easy.
Try this
HttpServletResponse response;
response.sendRedirect(".../webpage.xhtml");
I don't think we had this class back when you asked the question, but today there is an easy answer.
What you want to do is use the DataFormatter class. You pass this a cell, and it does its best to return you a string containing what Excel would show you for that cell. If you pass it a string cell, you'll get the string back. If you pass it a numeric cell with formatting rules applied, it will format the number based on them and give you the string back.
For your case, I'd assume that the numeric cells have an integer formatting rule applied to them. If you ask DataFormatter to format those cells, it'll give you back a string with the integer string in it.
Also, note that lots of people suggest doing cell.setCellType(Cell.CELL_TYPE_STRING)
, but the Apache POI JavaDocs quite clearly state that you shouldn't do this! Doing the setCellType
call will loose formatting, as the javadocs explain the only way to convert to a String with formatting remaining is to use the DataFormatter class.
To get the content of a directory you can use
$files = Get-ChildItem "C:\Users\gerhardl\Documents\My Received Files\"
Then you can loop over this variable as well:
for ($i=0; $i -lt $files.Count; $i++) {
$outfile = $files[$i].FullName + "out"
Get-Content $files[$i].FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}
An even easier way to put this is the foreach
loop (thanks to @Soapy and @MarkSchultheiss):
foreach ($f in $files){
$outfile = $f.FullName + "out"
Get-Content $f.FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}
Actually I believe de-normalising the tags table might be a better way forward, depending on scale.
This way, the tags table simply has tagid, itemid, tagname.
You'll get duplicate tagnames, but it makes adding/removing/editing tags for specific items MUCH more simple. You don't have to create a new tag, remove the allocation of the old one and re-allocate a new one, you just edit the tagname.
For displaying a list of tags, you simply use DISTINCT or GROUP BY, and of course you can count how many times a tag is used easily, too.
>>> a="Hello\u2026"
>>> print a.decode('unicode-escape')
Hello…
Run this:
init = tf.global_variables_initializer()
sess.run(init)
Or (depending on the version of TF that you have):
init = tf.initialize_all_variables()
sess.run(init)
There's a much easier way of doing this. You can assign a Name to your Window or UserControl, and then binding by ElementName.
Window1.xaml
<Window x:Class="QuizBee.Host.Window1"
x:Name="Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ListView ItemsSource="{Binding ElementName=Window1, Path=myDictionary}" />
</Window>
Window1.xaml.cs
public partial class Window1:Window
{
// the property must be public, and it must have a getter & setter
public Dictionary<string, myClass> myDictionary { get; set; }
public Window1()
{
// define the dictionary items in the constructor
// do the defining BEFORE the InitializeComponent();
myDictionary = new Dictionary<string, myClass>()
{
{"item 1", new myClass(1)},
{"item 2", new myClass(2)},
{"item 3", new myClass(3)},
{"item 4", new myClass(4)},
{"item 5", new myClass(5)},
};
InitializeComponent();
}
}
You can create a extension method:
public static IEnumerable<T> Do<T>(this IEnumerable<T> self, Action<T> action) {
foreach(var item in self) {
action(item);
yield return item;
}
}
And then use it in code:
listofCompany.Do(d=>d.Id = 1);
listofCompany.Where(d=>d.Name.Contains("Inc")).Do(d=>d.Id = 1);
I found two main problems with that implementation. First, when you import the vue.js
script you use type="JavaScript"
as content-type
which is wrong. You should remove this type
parameter because by default script
tags have text/javascript
as default content-type
. Or, just replace the type
parameter with the correct content-type
which is type="text/javascript"
.
The second problem is that your script is embedded in the same HTML file means that it may be triggered first and probably the vue.js
file was not loaded yet. You can fix this using a jQuery snippet $(function(){ /* ... */ });
or adding a javascript function as shown in this example:
// Verifies if the document is ready_x000D_
function ready(f) {_x000D_
/in/.test(document.readyState) ? setTimeout('ready(' + f + ')', 9) : f();_x000D_
}_x000D_
_x000D_
ready(function() {_x000D_
var demo = new Vue({_x000D_
el: '#demo',_x000D_
data: {_x000D_
message: 'Hello Vue.js!'_x000D_
}_x000D_
})_x000D_
});

I'll interpret your question as two questions: 1) why ->
even exists, and 2) why .
does not automatically dereference the pointer. Answers to both questions have historical roots.
Why does ->
even exist?
In one of the very first versions of C language (which I will refer as CRM for "C Reference Manual", which came with 6th Edition Unix in May 1975), operator ->
had very exclusive meaning, not synonymous with *
and .
combination
The C language described by CRM was very different from the modern C in many respects. In CRM struct members implemented the global concept of byte offset, which could be added to any address value with no type restrictions. I.e. all names of all struct members had independent global meaning (and, therefore, had to be unique). For example you could declare
struct S {
int a;
int b;
};
and name a
would stand for offset 0, while name b
would stand for offset 2 (assuming int
type of size 2 and no padding). The language required all members of all structs in the translation unit either have unique names or stand for the same offset value. E.g. in the same translation unit you could additionally declare
struct X {
int a;
int x;
};
and that would be OK, since the name a
would consistently stand for offset 0. But this additional declaration
struct Y {
int b;
int a;
};
would be formally invalid, since it attempted to "redefine" a
as offset 2 and b
as offset 0.
And this is where the ->
operator comes in. Since every struct member name had its own self-sufficient global meaning, the language supported expressions like these
int i = 5;
i->b = 42; /* Write 42 into `int` at address 7 */
100->a = 0; /* Write 0 into `int` at address 100 */
The first assignment was interpreted by the compiler as "take address 5
, add offset 2
to it and assign 42
to the int
value at the resultant address". I.e. the above would assign 42
to int
value at address 7
. Note that this use of ->
did not care about the type of the expression on the left-hand side. The left hand side was interpreted as an rvalue numerical address (be it a pointer or an integer).
This sort of trickery was not possible with *
and .
combination. You could not do
(*i).b = 42;
since *i
is already an invalid expression. The *
operator, since it is separate from .
, imposes more strict type requirements on its operand. To provide a capability to work around this limitation CRM introduced the ->
operator, which is independent from the type of the left-hand operand.
As Keith noted in the comments, this difference between ->
and *
+.
combination is what CRM is referring to as "relaxation of the requirement" in 7.1.8: Except for the relaxation of the requirement that E1
be of pointer type, the expression E1->MOS
is exactly equivalent to (*E1).MOS
Later, in K&R C many features originally described in CRM were significantly reworked. The idea of "struct member as global offset identifier" was completely removed. And the functionality of ->
operator became fully identical to the functionality of *
and .
combination.
Why can't .
dereference the pointer automatically?
Again, in CRM version of the language the left operand of the .
operator was required to be an lvalue. That was the only requirement imposed on that operand (and that's what made it different from ->
, as explained above). Note that CRM did not require the left operand of .
to have a struct type. It just required it to be an lvalue, any lvalue. This means that in CRM version of C you could write code like this
struct S { int a, b; };
struct T { float x, y, z; };
struct T c;
c.b = 55;
In this case the compiler would write 55
into an int
value positioned at byte-offset 2 in the continuous memory block known as c
, even though type struct T
had no field named b
. The compiler would not care about the actual type of c
at all. All it cared about is that c
was an lvalue: some sort of writable memory block.
Now note that if you did this
S *s;
...
s.b = 42;
the code would be considered valid (since s
is also an lvalue) and the compiler would simply attempt to write data into the pointer s
itself, at byte-offset 2. Needless to say, things like this could easily result in memory overrun, but the language did not concern itself with such matters.
I.e. in that version of the language your proposed idea about overloading operator .
for pointer types would not work: operator .
already had very specific meaning when used with pointers (with lvalue pointers or with any lvalues at all). It was very weird functionality, no doubt. But it was there at the time.
Of course, this weird functionality is not a very strong reason against introducing overloaded .
operator for pointers (as you suggested) in the reworked version of C - K&R C. But it hasn't been done. Maybe at that time there was some legacy code written in CRM version of C that had to be supported.
(The URL for the 1975 C Reference Manual may not be stable. Another copy, possibly with some subtle differences, is here.)
All above code have their own worth but with my personal experience just give a try with Picasso.
Picasso is a library specifically for this purpose, in-fact it will manage cache and all other network operations automatically.You will have to add library in your project and just write a single line of code to load image from remote URL.

I found an example online which seems to work well:
First you create a new ICertificatePolicy
using System.Security.Cryptography.X509Certificates;
using System.Net;
public class MyPolicy : ICertificatePolicy
{
public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request,
int certificateProblem)
{
//Return True to force the certificate to be accepted.
return true;
}
}
Then just use this prior to sending your http request like so:
System.Net.ServicePointManager.CertificatePolicy = new MyPolicy();

Have you tried using the MD5 implementation in hashlib? Note that hashing algorithms typically act on binary data rather than text data, so you may want to be careful about which character encoding is used to convert from text to binary data before hashing.
The result of a hash is also binary data - it looks like Flickr's example has then been converted into text using hex encoding. Use the hexdigest
function in hashlib to get this.
What I did to remove marker was this create a button who allow me do it
Hope i can help someone :)
//Button who active deleteBool
const button = document.getElementById('btn')
//Boolean who let me delete marker
let deleteBool = false
//Button function to enable boolean
button.addEventListener('click',()=>{

// Function to delete marker
const deleteMarker = (e) => {
if (deleteBool) {
e.target.removeFrom(map)

}
}
//Initiate map
var map = L.map('map').setView([51.505, -0.09], 13);
//Create one marker
let marker = L.marker([51.5, -0.09]).addTo(map)

A Bin file is a pure binary file with no memory fix-ups or relocations, more than likely it has explicit instructions to be loaded at a specific memory address. Whereas....
ELF files are Executable Linkable Format which consists of a symbol look-ups and relocatable table, that is, it can be loaded at any memory address by the kernel and automatically, all symbols used, are adjusted to the offset from that memory address where it was loaded into. Usually ELF files have a number of sections, such as 'data', 'text', 'bss', to name but a few...it is within those sections where the run-time can calculate where to adjust the symbol's memory references dynamically at run-time.
If I am not mistaken, it will be onunload event.

The code in question you're asking about comes from my answer given here. It was intended to solve the problem of comparing multiple bit arrays - i.e. collections of 1
and 0
.
any
and all
are useful when you can rely on the "truthiness" of values - i.e. their value in a boolean context. 1 is True
and 0 is False
, a convenience which that answer leveraged. 5 happens to also be True
, so when you mix that into your possible inputs... well. Doesn't work.
You could instead do something like this:
[len(set(x)) > 1 for x in zip(*d['Drd2'])]
It lacks the aesthetics of the previous answer (I really liked the look of any(x) and not all(x)
), but it gets the job done.
In Firebird, you can do this:
select "Hello world" from RDB$DATABASE;
RDB$DATABASE is a special table that always has one row.
Mysql 5.7.24 get root first login
step 1: get password from log
grep root@localhost /var/log/mysqld.log
Output
2019-01-17T09:58:34.459520Z 1 [Note] A temporary password is generated for root@localhost: wHkJHUxeR4)w
step 2: login with him to mysql
mysql -uroot -p'wHkJHUxeR4)w'
step 3: you put new root password
SET PASSWORD = PASSWORD('xxxxx');
you get ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
how fix it?
run this SET GLOBAL validate_password_policy=LOW;
Try Again SET PASSWORD = PASSWORD('xxxxx');
I would create a user control which holds a Label and a Text Box in it and simply create instances of that user control 'n' times. If you want to know a better way to do it and use properties to get access to the values of Label and Text Box from the user control, please let me know.
Simple way to do it would be:
int n = 4; // Or whatever value - n has to be global so that the event handler can access it
private void btnDisplay_Click(object sender, EventArgs e)
{
TextBox[] textBoxes = new TextBox[n];
Label[] labels = new Label[n];
for (int i = 0; i < n; i++)
{
textBoxes[i] = new TextBox();
// Here you can modify the value of the textbox which is at textBoxes[i]
labels[i] = new Label();
// Here you can modify the value of the label which is at labels[i]
}
// This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
for (int i = 0; i < n; i++)
{
this.Controls.Add(textBoxes[i]);
this.Controls.Add(labels[i]);
}
}
The code above assumes that you have a button btnDisplay
and it has a onClick
event assigned to btnDisplay_Click
event handler. You also need to know the value of n and need a way of figuring out where to place all controls. Controls should have a width and height specified as well.
To do it using a User Control simply do this.
Okay, first of all go and create a new user control and put a text box and label in it.
Lets say they are called txtSomeTextBox
and lblSomeLabel
. In the code behind add this code:
public string GetTextBoxValue()
{
return this.txtSomeTextBox.Text;
}
public string GetLabelValue()
{
return this.lblSomeLabel.Text;
}
public void SetTextBoxValue(string newText)
{
this.txtSomeTextBox.Text = newText;
}
public void SetLabelValue(string newText)
{
this.lblSomeLabel.Text = newText;
}
Now the code to generate the user control will look like this (MyUserControl is the name you have give to your user control):
private void btnDisplay_Click(object sender, EventArgs e)
{
MyUserControl[] controls = new MyUserControl[n];
for (int i = 0; i < n; i++)
{
controls[i] = new MyUserControl();
controls[i].setTextBoxValue("some value to display in text");
controls[i].setLabelValue("some value to display in label");
// Now if you write controls[i].getTextBoxValue() it will return "some value to display in text" and controls[i].getLabelValue() will return "some value to display in label". These value will also be displayed in the user control.
}
// This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
for (int i = 0; i < n; i++)
{
this.Controls.Add(controls[i]);
}
}
Of course you can create more methods in the usercontrol to access properties and set them. Or simply if you have to access a lot, just put in these two variables and you can access the textbox and label directly:
public TextBox myTextBox;
public Label myLabel;
In the constructor of the user control do this:
myTextBox = this.txtSomeTextBox;
myLabel = this.lblSomeLabel;
Then in your program if you want to modify the text value of either just do this.
control[i].myTextBox.Text = "some random text"; // Same applies to myLabel
Hope it helped :)
Converting int64
:
n := int64(32)
str := strconv.FormatInt(n, 10)
fmt.Println(str)
// Prints "32"
I wrote this function that extracts what you are looking for based on the address_components
returned from the gmaps API. This is the city (for example).
export const getAddressCity = (address, length) => {
const findType = type => type.types[0] === "locality"
const location = address.map(obj => obj)
const rr = location.filter(findType)[0]
return (
length === 'short'
? rr.short_name
: rr.long_name
)
}
Change locality
to administrative_area_level_1
for the State etc.
In my js code I am using like so:
const location =`${getAddressCity(address_components, 'short')}, ${getAddressState(address_components, 'short')}`
Will return: Waltham, MA
I've found a better way how to manage JS packages in my project with NPM Gulp/Grunt task runners. I don't like the idea to have a NPM with another layer of javascript library to handle the "automation", and my number one requirement is to simple run the npm update without any other worries about to if I need to run gulp stuff, if it successfully copied everything and vice versa.
The NPM way:
- The JS minifier is already bundled in the ASP.net core, look for bundleconfig.json so this is not an issue for me (not compiling something custom)
- The good thing about NPM is that is have a good file structure so I can always find the pre-compiled/minified versions of the dependencies under the node_modules/module/dist
- I'm using an NPM node_modules/.hooks/{eventname} script which is handling the copy/update/delete of the Project/wwwroot/lib/module/dist/.js files, you can find the documentation here https://docs.npmjs.com/misc/scripts (I'll update the script that I'm using to git once it'll be more polished) I don't need additional task runners (.js tools which I don't like) what keeps my project clean and simple.
The python way:
https://pypi.python.org/pyp... but in this case you need to maintain the sources manually
xlim
and ylim
don't cut it here. You need to use expand_limits
, scale_x_continuous
, and scale_y_continuous
. Try:
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0)) + scale_y_continuous(expand = c(0, 0))
You may need to adjust things a little to make sure points are not getting cut off (see, for example, the point at x = 5
and y = 5
.
This worked for me on Ubuntu 12.04.
pip install --index-url=https://pypi.python.org/simple/ -U scikit-learn
no need to do a replacement. the regex will give you what u wanted directly:

You're looking for the toggle_comment
command. (Edit > Comment > Toggle Comment)
By default, this command is mapped to:
This command also takes a block
argument, which allows you to use block comments instead of single lines (e.g. /* ... */
as opposed to // ...
in JavaScript). By default, the following key combinations are mapped to toggle block comments:
I had been facing the same issue,
For Chrome and Firefox but everything was working how it should in internet explorer. I found that making the CSS file UTF-8 made it work for chrome.
Also make sure the Rewrite Engline is turned on after editing the .htaccess file
sudo a2enmod rewrite
If the plugin you want to install is not listed in the Plugins Admin, you may still install it manually. The plugin (in the DLL form) should be placed in the plugins subfolder of the Notepad++ Install Folder, under the subfolder with the same name of plugin binary name without file extension.
For example, if the plugin you want to install named myAwesomePlugin.dll, you should install it with the following path:
%PROGRAMFILES(x86)%\Notepad++\plugins\myAwesomePlugin\myAwesomePlugin.dll
or
%PROGRAMFILES%\Notepad++\plugins\myAwesomePlugin\myAwesomePlugin.dll
Once you installed the plugin, you can use (and you may configure) it via the menu “Plugins”.
Restart the Notepad++ after putting the plugin
Just an update:
You should use ::ng-deep
instead of /deep/
which seems to be deprecated.
Per documentation:
The shadow-piercing descendant combinator is deprecated and support is being removed from major browsers and tools. As such we plan to drop support in Angular (for all 3 of /deep/, >>> and ::ng-deep). Until then ::ng-deep should be preferred for a broader compatibility with the tools.

Implementing Google translate html code is very easy. Use this code on your project, hope it will help you.
<div id="google_translate_element"></div>
<script>
function googleTranslateElementInit() {
new google.translate.TranslateElement({
pageLanguage: 'en'
}, 'google_translate_element');
}
</script>
<script src="http://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
If it's just a test installation of Docker (ie not production) and you don't care about doing a nuclear clean, you can:
clean all containers:
docker ps -a | sed '1 d' | awk '{print $1}' | xargs -L1 docker rm
clean all images:
docker images -a | sed '1 d' | awk '{print $3}' | xargs -L1 docker rmi -f
Again, I use this in my ec2 instances when developing Docker, not in any serious QA or Production path. The great thing is that if you have your Dockerfile(s), it's easy to rebuild and or docker pull
.
ul>li
selects all li
that are a direct child of ul
whereas ul li
selects all li
that are anywhere within (descending as deep as you like) a ul
For HTML:
<ul>
<li><span><a href='#'>Something</a></span></li>
<li><a href='#'>or Other</a></li>
</ul>
And CSS:
li a{ color: green; }
li>a{ color: red; }
The colour of Something
will remain green but or Other
will be red
Part 2, you should write the rule to be appropriate to the situation, I think the speed difference would be incredibly small, and probably overshadowed by the extra characters involved in writing more code, and definitely overshadowed by the time taken by the developer to think about it.
However, as a rule of thumb, the more specific you are with your rules, the faster the CSS engines can locate the DOM elements you want to apply it to, so I expect li>a
is faster than li a
as the DOM search can be cut short earlier. It also means that nested anchors are not styled with that rule, is that what you want? <~~ much more pertinent question.
Interesting to note. Tried:
alert("Some \
string \
wrapped \
across \
mutliples lines.")
And this worked. However, on accident!, there was a space character following the final backslash (all other backslashes were at the end of the line). And this caused an error in the javascript! Removing this space fixed the error, though.
This is in ADT for Android using Cordova.
Ancient question, but 3Dave's answer supplied the easiest approach. I needed a little helper method to generate a Sql script to decode an enum value in the database for debugging. It worked great:
public static string EnumToCheater<T>() {
var sql = "";
foreach (var enumValue in Enum.GetValues(typeof(T)))
sql += $@"when {(int) enumValue} then '{enumValue}' ";
return $@"case ?? {sql}else '??' end,";
}
I have it in a static method, so usage is:
var cheater = MyStaticClass.EnumToCheater<MyEnum>()
There is a builtin function all
:
all (x > limit for x in my_list)
Being limit the value greater than which all numbers must be.
Just throwing this in in case it helps, I had this issue and the reason for me was because when I bundled my Angular stuff I referenced the main app file as "AngularWebApp" instead of "AngularWebApp.js", hope this helps.
This seems to work:
def sanitize_utf8(string)
return nil if string.nil?
return string if string.valid_encoding?
string.chars.select { |c| c.valid_encoding? }.join
end
With typescript 2.8, you can use the new built-in Exclude
type. The 2.8 release notes actually mention this in the section "Predefined conditional types":
Note: The Exclude type is a proper implementation of the Diff type suggested here. [...] We did not include the Omit type because it is trivially written as
Pick<T, Exclude<keyof T, K>>
.
Applying this to your example, type XY could be defined as:
type XY = Pick<XYZ, Exclude<keyof XYZ, "z">>
You can save the whole jstl object as a Javascript object by converting the whole object to json. It is possible by Jackson in java.
import com.fasterxml.jackson.databind.ObjectMapper;
public class JsonUtil{
public static String toJsonString(Object obj){
ObjectMapper objectMapper = ...; // jackson object mapper
return objectMapper.writeValueAsString(obj);
}

You may have a look at these slides from the last italian pycon (pdf): The author listed most of the library for doing scraping and autoted browsing in python. so you may have a look at it.
I like very much twill (which has already been suggested), which has been developed by one of the authors of nose and it is specifically aimed at testing web sites.
This will get selected value from multi-value select boxes: $("#id option:selected").val()
There's no reliable way to detect first run, as the shared preferences way is not always safe, the user can delete the shared preferences data from the settings! a better way is to use the answers here Is there a unique Android device ID? to get the device's unique ID and store it somewhere in your server, so whenever the user launches the app you request the server and check if it's there in your database or it is new.
The shortcut is: CTRL+_

If you pushed to GitHub, force pushing is not enough, delete the repository or contact support
Even if you force push one second afterwards, it is not enough as explained below.
The only valid courses of action are:
is what leaked a changeable credential like a password?
yes: modify your passwords immediately, and consider using more OAuth and API keys!
no (naked pics):
do you care if all issues in the repository get nuked?
no: delete the repository
yes:
Force pushing a second later is not enough because:
GitHub keeps dangling commits for a long time.
GitHub staff does have the power to delete such dangling commits if you contact them however.
I experienced this first hand when I uploaded all GitHub commit emails to a repo they asked me to take it down, so I did, and they did a gc
. Pull requests that contain the data have to be deleted however: that repo data remained accessible up to one year after initial takedown due to this.
Dangling commits can be seen either through:
One convenient way to get the source at that commit then is to use the download zip method, which can accept any reference, e.g.: https://github.com/cirosantilli/myrepo/archive/SHA.zip
It is possible to fetch the missing SHAs either by:
type": "PushEvent"
. E.g. mine: https://api.github.com/users/cirosantilli/events/public (Wayback machine)There are scrappers like http://ghtorrent.org/ and https://www.githubarchive.org/ that regularly pool GitHub data and store it elsewhere.
I could not find if they scrape the actual commit diff, and that is unlikely because there would be too much data, but it is technically possible, and the NSA and friends likely have filters to archive only stuff linked to people or commits of interest.
If you delete the repository instead of just force pushing however, commits do disappear even from the API immediately and give 404, e.g. https://api.github.com/repos/cirosantilli/test-dangling-delete/commits/8c08448b5fbf0f891696819f3b2b2d653f7a3824 This works even if you recreate another repository with the same name.
To test this out, I have created a repo: https://github.com/cirosantilli/test-dangling and did:
git init
git remote add origin [email protected]:cirosantilli/test-dangling.git
touch a
git add .
git commit -m 0
git push
touch b
git add .
git commit -m 1
git push
touch c
git rm b
git add .
git commit --amend --no-edit
git push -f

git filter-repo
is now officially recommended over git filter-branch
This is mentioned in the manpage of git filter-branch
in Git 2.5 itself.
With git filter repo, you could either remove certain files with: Remove folder and its contents from git/GitHub's history
pip install git-filter-repo
git filter-repo --path path/to/remove1 --path path/to/remove2 --invert-paths
This automatically removes empty commits.
Or you can replace certain strings with: How to replace a string in a whole Git history?
git filter-repo --replace-text <(echo 'my_password==>xxxxxxxx')
overflow-x: scroll;
overflow-y: hidden;

It works for me:

</div>
This approach avoids the warnings while preserving the array-oriented evaluation.

This will do it:
wc -c filename
If you want only the count without the filename being repeated in the output:
wc -c < filename
Edit:
Use -m
to count character instead of bytes (as shown in Sébastien's answer).
Otherwise use seaborn data sets which are actual pandas data frames:
import seaborn
iris = seaborn.load_dataset("iris")
type(iris)
# <class 'pandas.core.frame.DataFrame'>
Compare with scikit learn data sets:
from sklearn import datasets
iris = datasets.load_iris()
type(iris)
# <class 'sklearn.utils.Bunch'>
dir(iris)
# ['DESCR', 'data', 'feature_names', 'filename', 'target', 'target_names']
React.createRef
(class components)class ClassApp extends React.Component {
inputRef = React.createRef<HTMLInputElement>();
render() {
return <input type="text" ref={this.inputRef} />
}
}
Note: Omitting the old String Refs legacy API here...
React.useRef
(Hooks / function components)const FunctionApp = () => {
const inputRef = React.useRef<HTMLInputElement>(null) // note the passed in `null` arg
return <input type="text" ref={inputRef} />
}
Mutable refs for arbitrary stored values:
const FunctionApp = () => {
const renderCountRef = useRef(0)
useEffect(() => {
renderCountRef.current += 1
})
// ... other render code
}
Note: Don't initialize useRef
with null
in this case. It would make the renderCountRef
type readonly
(see example). If you need to provide null
as initial value, do this:
const renderCountRef = useRef<number | null>(null)
// Function component example
const FunctionApp = () => {
const handleDomNodeChange = (domNode: HTMLInputElement | null) => {
// ... do something with changed dom node.
}
return <input type="text" ref={handleDomNodeChange} />
}
This is what I was looking for and I did for sorting an Array of Arrays based on another Array:

if(el == arr1[i]){_x000D_
a.push(el);_x000D_
} _x000D_

return a;_x000D_

const arr = [['fname', 'city', 'name'],_x000D_

console.log(sortArray(arr,arr1));

I'm using Sublime Text 3.2.1, a 4k display and a Mac. Tab titles and the sidebar are difficult to read with default ST3 settings. I used the menus Sublime Text -> Preferences -> Settings which opens two files: Preferences.sublime-settings--Default and Preferences.sublime-settings--User.
You can only edit the User file. The Default file is useful for showing what variables you can set. Around line 350 of the Default file are two variables as shown below:
// Magnifies the entire user interface. Sublime Text must be restarted for
// this to take effect.
"ui_scale": 1.0,
// Linux only. Sets the app DPI scale - a decimal number such as 1.0, 1.5,
// 2.0, etc. A value of 0 auto-detects the DPI scale. Sublime Text must be
// restarted for this to take effect.
"dpi_scale": 0,
"dpi_scale": 3.0
did nothing on my Mac "ui_scale": 1.5
worked well. The following is my User file.
{
"dictionary": "Packages/Language - English/en_US.dic",
"font_size": 17,
"ignored_packages":
[
"Vintage"
],
"theme": "Default.sublime-theme",
"ui_scale": 1.5
}
In your template
template <void (*T)(int &)>
void doOperation()
The parameter T
is a non-type template parameter. This means that the behaviour of the template function changes with the value of the parameter (which must be fixed at compile time, which function pointer constants are).
If you want somthing that works with both function objects and function parameters you need a typed template. When you do this, though, you also need to provide an object instance (either function object instance or a function pointer) to the function at run time.
template <class T>
void doOperation(T t)
{
int temp=0;
t(temp);
std::cout << "Result is " << temp << std::endl;
}
There are some minor performance considerations. This new version may be less efficient with function pointer arguments as the particular function pointer is only derefenced and called at run time whereas your function pointer template can be optimized (possibly the function call inlined) based on the particular function pointer used. Function objects can often be very efficiently expanded with the typed template, though as the particular operator()
is completely determined by the type of the function object.
TLDR : check if packaging
element inside the pom.xml file is set to jar
.
Like this - <packaging>jar</packaging>
. If it set to pom
your target folder will not be created even after you Clean and Build your project and Maven executable won't be able to find .class
files (because they don't exist), after which you get Error: Could not find or load main class your.package.name.MainClass
After creating a Maven POM project in Netbeans 8.2, the content of the default pom.xml
file are as follows -
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany</groupId>
<artifactId>myproject</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
</project>
Here packaging
element is set to pom
. Hence the target
directory is not created as we are not enabling maven to package our application as a jar
file. Change it to jar
then Clean and Build your project, you should see target directory created at root location. Now you should be able to run that java file with main method.
When no packaging is declared, Maven assumes the packaging as jar
. Other core packaging values are pom
, war
, maven-plugin
, ejb
, ear
, rar
. These define the goals that execute on each corresponsding build life-cycle phase of that package. See more here
If it's inside a closure, i'm pretty sure you can't.
Otherwise you just do functionName();
and hit return.
You need to add this as the last line...
HttpContext.Current.Response.Cookies.Add(userid);
When you need to read the value of the cookie, you'd use a method similar to this:
string cookieUserID= String.Empty;
try
{
if (HttpContext.Current.Request.Cookies["userid"] != null)
{
cookieUserID = HttpContext.Current.Request.Cookies["userid"];
}
}
catch (Exception ex)
{
//handle error
}
return cookieUserID;
In javascript, it is not possible but yes with the help of “Web Clips” we can create a "add to home screen" icon or shortcut in iPhone( by the code file of .mobileconfig)
http://appdistro.cttapp.com/webclip/
after create a mobileconfig file we can pass this url in iphone safari browser install certificate and after done it check your iphone home screen there is a shortcut icon of your Web page or webapp..
I checked how .NET determines the main window.
My finding showed that it also uses EnumWindows()
.
This code should do it similarly to the .NET way:
struct handle_data {
unsigned long process_id;
HWND window_handle;
};
HWND find_main_window(unsigned long process_id)
{
handle_data data;
data.process_id = process_id;
data.window_handle = 0;
EnumWindows(enum_windows_callback, (LPARAM)&data);
return data.window_handle;
}
BOOL CALLBACK enum_windows_callback(HWND handle, LPARAM lParam)
{
handle_data& data = *(handle_data*)lParam;
unsigned long process_id = 0;
GetWindowThreadProcessId(handle, &process_id);
if (data.process_id != process_id || !is_main_window(handle))
return TRUE;
data.window_handle = handle;
return FALSE;
}
BOOL is_main_window(HWND handle)
{

I was facing an issue where Slick carousel wasn't refreshing on new data, it was appending new slides to previous ones, I found an answer which solved my problem, it's very simple.
try unslick, then assign your new data which is being rendered inside slick carousel, and then initialize slick again. these were the steps for me:
jQuery('.class-or-#id').slick('unslick');
myData = my-new-data;
jQuery('.class-or-#id').slick({slick options});
Note: check slick website for syntax just in case. also make sure you are not using unslick before slick is even initialized, what that means is simply initialize (like this jquery('.my-class').slick({options}
); the first ajax call and once it is initialized then follow above steps, you may wanna use if else
json_decode($data, true); // Returns data in array format
json_decode($data); // Returns collections
So, If want an array than you can pass the second argument as 'true' in json_decode
function.
docker volume create pgdata
or you can set it to the compose file
version: "3"
services:
db:
image: postgres
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgress
- POSTGRES_DB=postgres
ports:
- "5433:5432"
volumes:
- pgdata:/var/lib/postgresql/data
networks:
- suruse
volumes:
pgdata:
It will create volume name pgdata and mount this volume to container's path.
docker volume inspect pgdata
// output will be
[
{
"Driver": "local",
"Labels": {},
"Mountpoint": "/var/lib/docker/volumes/pgdata/_data",
"Name": "pgdata",
"Options": {},
"Scope": "local"
}
]
I hope this is helpful to you.
Please try this code,
@Html.DropDownListFor(model => model.Items, new List<SelectListItem>
{ new SelectListItem{Text="Deactive", Value="False"},
new SelectListItem{Text="Active", Value="True", Selected = true},
})
You can use std::to_string in C++11
double d = 3.0;
std::string str = std::to_string(d);
I had to call a function once my dataService was initialized, instead, I called it inside the constructor, that worked for me.
\App::call('App\Http\Controllers\MyController@getFoo')
When you print it with this print 'I\nwould\nexpect\nmultiple\nlines'
you would get:
I
would
expect
multiple
lines
The \n
is a new line character specially used for marking END-OF-TEXT. It signifies the end of the line or text. This characteristics is shared by many languages like C, C++ etc.
jQuery might be missing.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
Just add the attribute disabled
to the element (or use jQuery to do it for you). Disabled prevents the input from being focused or selected at all.
Even simpler is to use:
(?P<project_id>\w+|)
The "(a|b)" means a or b, so in your case it would be one or more word characters (\w+) or nothing.
So it would look like:
url(
r'^project_config/(?P<product>\w+)/(?P<project_id>\w+|)/$',
'tool.views.ProjectConfig',
name='project_config'
),
This error message is displayed if the path you pass to Bitmap.Save()
is invalid (folder doesn't exist etc).
Using an escaped string (a.k.a. escaped value):
width: ~"calc(100% - 200px)";
Also, in case you need to mix Less math with escaped strings:
width: calc(~"100% - 15rem +" (10px+5px) ~"+ 2em");
Compiles to:
width: calc(100% - 15rem + 15px + 2em);
This works as Less concatenates values (the escaped strings and math result) with a space by default.
Not sure if this is a good practice, but I noticed I can also get just the value by casting the series as float
.
e.g.
rate
3 0.042679
Name: Unemployment_rate, dtype: float64
float(rate)
0.0426789
What worked for me was:
.git/logs/refs/remotes/origin/branch

git gc --prune=now
I actually think it may retain cached information when you close out the UIWebView
. I've tried removing a UIWebView
from my UIViewController
, releasing it, then creating a new one. The new one remembered exactly where I was at when I went back to an address without having to reload everything (it remembered my previous UIWebView
was logged in).
So a couple of suggestions:
[[NSURLCache sharedURLCache] removeCachedResponseForRequest:NSURLRequest];
This would remove a cached response for a specific request. There is also a call that will remove all cached responses for all requests ran on the UIWebView
:
[[NSURLCache sharedURLCache] removeAllCachedResponses];
After that, you can try deleting any associated cookies with the UIWebView
:
for(NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {
if([[cookie domain] isEqualToString:someNSStringUrlDomain]) {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
}
}
Swift 3:
// Remove all cache
URLCache.shared.removeAllCachedResponses()
// Delete any associated cookies
if let cookies = HTTPCookieStorage.shared.cookies {
for cookie in cookies {
HTTPCookieStorage.shared.deleteCookie(cookie)
}
}
#reading out the file at once in a list and then printing one-by-one

The plus sign is the historic encoding for a space character in URL parameters, as documented in the help for the urlencode()
function.
That same page contains the answer you need - use rawurlencode()
instead to get RFC 3986 compatible encoding.
var Line = textBox1.Text + "," + textBox2.Text;
File.AppendAllText(@"C:\Documents\m2.txt", Line + Environment.NewLine);
With quotes around the date:

I think it's important to mention little difference between 'self' and 'static' in PHP as 'best answer' uses 'static' which can give confusing result to some people.
<?php
class X {
function getStatic() {
// gets THIS class of instance of object
// that extends class in which is definied function
return static::class;
}
function getSelf() {
// gets THIS class of class in which function is declared
return self::class;
}
}
class Y extends X {
}
class Z extends Y {
}
$x = new X();
$y = new Y();
$z = new Z();
echo 'X:' . $x->getStatic() . ', ' . $x->getSelf() .
', Y: ' . $y->getStatic() . ', ' . $y->getSelf() .
', Z: ' . $z->getStatic() . ', ' . $z->getSelf();
Results:
X: X, X
Y: Y, X
Z: Z, X
The view-source url prefix trick didn't work for me using chrome on an iphone. There are apps I could have installed to do this I guess but for whatever reason I just preferred to do it myself rather than install 'yet another app'.
I found this nice quick tutorial for how to setup a bookmark on mobile safari that will automatically open the view source of a page: https://appletoolbox.com/2014/03/how-to-view-webpage-html-source-codes-on-ipad-iphone-no-app-required/
It worked flawlessly for me and now I have it set as a permanent bookmark any time I want, with no app installed.
Edit: There are basically 6 steps which should work for either Chrome or Safari. Instructions for Safari are:
javascript:(function(){var a=window.open('about:blank').document;a.write('<!DOCTYPE html><html><head><title>Source of '+location.href+'</title><meta name="viewport" content="width=device-width" /></head><body></body></html>');a.close();var b=a.body.appendChild(a.createElement('pre'));b.style.overflow='auto';b.style.whiteSpace='pre-wrap';b.appendChild(a.createTextNode(document.documentElement.innerHTML))})();
I think, you could also do something like...
setTimeout(function(){
$(".message-class").trigger("click");
}, 5000);
and do your animated effects on the event-click...
$(".message-class").click(function() {
//your event-code
});
Greetings,
The thing you can do is create a .bat that will execute the .jar file created, checking if there is a JRE present.
From Mitch useful link (source)
java -classpath myprogram.jar de.vogella.eclipse.ide.first.MyFirstClass
This can be used into your batch...
In case of one request parameter it is simplier to use mediainfo and its output formatting like this (for duration; answer in milliseconds)

According to Html5 specs you should use -- element.options[e.selectedIndex].text
e.g. if you have select box like below :
<select id="selectbox1">
<option value="1">First</option>
<option value="2" selected="selected">Second</option>
<option value="3">Third</option>
</select>
<br/>
<button onClick="GetItemValue('selectbox1');">Get Item</button>
you can get value using following script :
<script>
function GetItemValue(q) {
var e = document.getElementById(q);
var selValue = e.options[e.selectedIndex].text ;
alert("Selected Value: "+selValue);
}
</script>
Tried and tested.
I've a snippet that shows, how to get the spacings of elements with jQuery:
/* messing vertical spaces of block level elements with jQuery in pixels */
console.clear();
var jObj = $('selector');
for(var i = 0, l = jObj.length; i < l; i++) {
//jObj.eq(i).css('display', 'block');
console.log('jQuery object:', jObj.eq(i));
console.log('plain element:', jObj[i]);
console.log('without spacings - jObj.eq(i).height(): ', jObj.eq(i).height());
console.log('with padding - jObj[i].clientHeight: ', jObj[i].clientHeight);
console.log('with padding and border - jObj.eq(i).outerHeight(): ', jObj.eq(i).outerHeight());
console.log('with padding, border and margin - jObj.eq(i).outerHeight(true):', jObj.eq(i).outerHeight(true));
console.log('total vertical spacing: ', jObj.eq(i).outerHeight(true) - jObj.eq(i).height());
}
You can use like below
-(void)myMethod
{
NSString* htmlStr = @"<some>html</string>";
NSString* strWithoutFormatting = [self stringByStrippingHTML:htmlStr];
}
-(NSString *)stringByStrippingHTML:(NSString*)str
{
NSRange r;
while ((r = [str rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
{
str = [str stringByReplacingCharactersInRange:r withString:@""];
}
return str;
}
For me it was import issue, hope it helps. default import by WebStorm was wrong.
replace
import connect from "react-redux/lib/connect/connect";
with
import {connect} from "react-redux";
The key idea is you form a set of the rows you want to remove, and keep the complement of that set.
In R, the complement of a set is given by the '-' operator.
So, assuming the data.frame
is called myData
:
myData[-c(2, 4, 6), ] # notice the -
Of course, don't forget to "reassign" myData
if you wanted to drop those rows entirely---otherwise, R just prints the results.
myData <- myData[-c(2, 4, 6), ]
Try this:
If [ $a -lt 4 ] || [ $a -gt 64 ] ; then \n
Something something \n
elif [ $a -gt 4 ] || [ $a -lt 64 ] ; then \n
Something something \n
else \n
Yes it works for me :) \n
Perhaps the best choice to avoid linking containers issues are the docker networking features
But to make this work, docker creates entries in the /etc/hosts for each container from assigned names to each container.
with docker-compose --x-networking -up is something like [docker_compose_folder]-[service]-[incremental_number]
To not depend on unexpected changes in these names you should use the parameter
container_name
in your docker-compose.yml as follows:
php:
container_name: waapi_php_1
build: config/docker/php
ports:
- "42022:22"
volumes:
- .:/var/www/html
env_file: config/docker/php/.env.development
Making sure that it is the same name assigned in your configuration file for this service. I'm pretty sure there are better ways to do this, but it is a good approach to start.
IntelliJ's built-in SSH client seems to hash its known_hosts
, but the one I had had its host names in clear text.
When I deleted the file and let IntelliJ create a new one, with only my (hashed) GitLab server and nothing else, it worked.
It's also not possible to mix it - keep some unhashed entries together with hashed entries for IntelliJ. So, you have to configure your other SSH clients to use hashed hosts.
I love jQuery's method chaining. Simply do...
var value = $("#text").val().replace('.',':');
//Or if you want to return the value:
return $("#text").val().replace('.',':');
Use the following methods
1: Method one
var count = 123;
var message = $"Rows count is: {count}";
2: Method two
var count = 123;
var message = "Rows count is:" + count;
3: Method three
var count = 123;
var message = string.Format("Rows count is:{0}", count);
4: Method four
var count = 123;
var message = @"Rows
count
is:{0}" + count;
5: Method five
var count = 123;
var message = $@"Rows
count
is: {count}";
SELECT @variable1 = col1, @variable2 = col2
FROM table1
Turn on Client Statistics by doing one of the following:
Then you get a new tab which records the timings, IO data and rowcounts etc for (up to) the last 10 exections (plus averages!):
Your best option here, is to use the Query String to 'send' the value.

For anyone who wants to ignore files locally in a submodule:
Edit my-parent-repo/.git/modules/my-submodule/info/exclude

file.
You can use max-height
in an inline style
attribute, as below:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
To use scrolling with content that overflows a given max-height
, you can alternatively try the following:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>
To restrict the height to a fixed value you can use something like this.
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
Specify the same value for both max-height
and min-height
(either in pixels or in points – as long as it’s consistent).
You can also put the same styles in css class in a stylesheet (or a style
tag as shown below) and then include the same in your tag. See below:
Style Code:
.fixed-panel {
min-height: 10;
max-height: 10;
overflow-y: scroll;
}
Apply Style :
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>
Hope this helps with your need.
.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])
Python uses key,direction. You can use the above way.
So in your case you can do this
for post in db.posts.find().sort('entities.user_mentions.screen_name',pymongo.ASCENDING):
print post
From git-blame:
Annotates each line in the given file with information from the revision which last modified the line. Optionally, start annotating from the given revision.
When specified one or more times, -L restricts annotation to the requested lines.
Example:
[email protected]:~# git blame .htaccess
...
^e1fb2d7 (John Doe 2015-07-03 06:30:25 -0300 4) allow from all
^72fgsdl (Arthur King 2015-07-03 06:34:12 -0300 5)
^e1fb2d7 (John Doe 2015-07-03 06:30:25 -0300 6) <IfModule mod_rewrite.c>
^72fgsdl (Arthur King 2015-07-03 06:34:12 -0300 7) RewriteEngine On
...
Please note that git blame
does not show the per-line modifications history in the chronological sense.
It only shows who was the last person to have changed a line in a document up to the last commit in HEAD
.
That is to say that in order to see the full history/log of a document line, you would need to run a git blame path/to/file
for each commit in your git log
.
If you don't want to wait for .NET 4.0, you could implement your own Zip
method. The following works with .NET 2.0. You can adjust the implementation depending on how you want to handle the case where the two enumerations (or lists) have different lengths; this one continues to the end of the longer enumeration, returning the default values for missing items from the shorter enumeration.
static IEnumerable<KeyValuePair<T, U>> Zip<T, U>(IEnumerable<T> first, IEnumerable<U> second)
{
IEnumerator<T> firstEnumerator = first.GetEnumerator();
IEnumerator<U> secondEnumerator = second.GetEnumerator();
while (firstEnumerator.MoveNext())
{
if (secondEnumerator.MoveNext())
{
yield return new KeyValuePair<T, U>(firstEnumerator.Current, secondEnumerator.Current);
}
else
{
yield return new KeyValuePair<T, U>(firstEnumerator.Current, default(U));
}
}
while (secondEnumerator.MoveNext())
{
yield return new KeyValuePair<T, U>(default(T), secondEnumerator.Current);
}
}
static void Test()
{
IList<string> names = new string[] { "one", "two", "three" };
IList<int> ids = new int[] { 1, 2, 3, 4 };
foreach (KeyValuePair<string, int> keyValuePair in ParallelEnumerate(names, ids))
{
Console.WriteLine(keyValuePair.Key ?? "<null>" + " - " + keyValuePair.Value.ToString());
}
}
Not 100% sure about the relationship between these two entities but here goes:
IList<Splitting> res = (from s in [data source]
where s.Customer.CompanyID == [companyID] &&
s.CustomerID == [customerID]
select s).ToList();
IList<Splitting> res = [data source].Splittings.Where(
x => x.Customer.CompanyID == [companyID] &&
x.CustomerID == [customerID]).ToList();
As @Eiríkr Útlendi noted, the accepted solution only considers two white space characters: the horizontal tab (U+0009), and a breaking space (U+0020). It does not consider other whitespace characters such as non-breaking spaces (which happen to be in the text I am trying to deal with). A more complete whitespace character listing is included on Wikipedia and also referenced in the linked Perl answer. A simple C# solution that accounts for these other characters can be built using character class subtraction
[\s-[\r\n]]
or, including Eiríkr Útlendi's solution, you get
[\s\u3000-[\r\n]]
Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.
You've got:
//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]
Which translates into:
Get me all the elements that have an ID
that contains ctl00_btnAircraftMapCell
. Out of these elements, get any child elements that have a title
that contains Select Seat
.
What you actually want is:
//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]
Which translates into:
Get me all the anchor elements that have both: an id
that contains ctl00_btnAircraftMapCell
and a title
that contains Select Seat
.
Use stat
to get the creation time. You can compare the time in the format YYYY-MM-DD HH:MM:SS
lexicographically.
This work on Linux with modification time, creation time is not supported. On AIX, the -c
option might not be supported, but you should be able to get the information anyway, using grep
if nothing else works.

I had a similar problem. I had to schedule bunch of tasks that should be executed during a day using ScheduledExecutorService
.
This was solved by one task starting at 3:30 AM scheduling all other tasks relatively to his current time. And rescheduling himself for the next day at 3:30 AM.
With this scenario daylight savings are not an issue anymore.

After looking into many answers (most of them are correct for their scenarios) and none of them fix my problem I realized that my case is a bit different:
In my weird scenario my component was being rendered inside the state and therefore couldn't be updated. Below is a simple example:
constructor() {
this.myMethod = this.myMethod.bind(this);
this.changeTitle = this.changeTitle.bind(this);
this.myMethod();
}
changeTitle() {
this.setState({title: 'I will never get updated!!'});
}
myMethod() {
this.setState({body: <div>{this.state.title}</div>});
}
render() {
return <>
{this.state.body}
<Button onclick={() => this.changeTitle()}>Change Title!</Button>
</>
}
After refactoring the code to not render the body from state it worked fine :)
In my case an unexpected error notice in the source code stopped the facebook crawler from parsing the (correctly set) og-meta tags.
I was using the HTTP_ACCEPT_LANGUAGE
header, which worked fine for regular browser requests but not for the crawler, as it obviously won't use/set it.
Therefore, it was crucial for me to use the facebook's debugger feature See exactly what our scraper sees for your URL
, as the error notice only could only be seen there (but not through the regular 'view source code'-browser feature).
Sonatype Nexus and Apache Maven are two pieces of software that often work together but they do very different parts of the job. Nexus provides a repository while Maven uses a repository to build software.
Here's a quote from "What is Nexus?":
Nexus manages software "artifacts" required for development. If you develop software, your builds can download dependencies from Nexus and can publish artifacts to Nexus creating a new way to share artifacts within an organization. While Central repository has always served as a great convenience for developers you shouldn't be hitting it directly. You should be proxying Central with Nexus and maintaining your own repositories to ensure stability within your organization. With Nexus you can completely control access to, and deployment of, every artifact in your organization from a single location.
And here is a quote from "Maven and Nexus Pro, Made for Each Other" explaining how Maven uses repositories:
Maven leverages the concept of a repository by retrieving the artifacts necessary to build an application and deploying the result of the build process into a repository. Maven uses the concept of structured repositories so components can be retrieved to support the build. These components or dependencies include libraries, frameworks, containers, etc. Maven can identify components in repositories, understand their dependencies, retrieve all that are needed for a successful build, and deploy its output back to repositories when the build is complete.
So, when you want to use both you will have a repository managed by Nexus and Maven will access this repository.
On macOS, you can use DTrace instead. The "Instruments" app is a nice GUI for that, it comes with XCode afaik.
Another approach is to use new conditional annotations. Since plain Spring 4 you can use @Conditional annotation:
@Component("foo")
@Conditional(FooCondition.class)
class Foo {
...
}
and define conditional logic for registering Foo component:
public class FooCondition implements Condition{
@Override
public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
// return [your conditional logic]
}
}
Conditional logic can be based on context, because you have access to bean factory. For Example when "Bar" component is not registered as bean:
return !context.getBeanFactory().containsBean(Bar.class.getSimpleName());
With Spring Boot (should be used for EVERY new Spring project), you can use these conditional annotations:
@ConditionalOnBean
@ConditionalOnClass
@ConditionalOnExpression
@ConditionalOnJava
@ConditionalOnMissingBean
@ConditionalOnMissingClass
@ConditionalOnNotWebApplication
@ConditionalOnProperty
@ConditionalOnResource
@ConditionalOnWebApplication
You can avoid Condition class creation this way. Refer to Spring Boot docs for more detail.
on Mac:
select all matches: Command + Shift + L
but if you just want to select another match up coming next: Command + D
To make a inline-block element align center horizontally in its parent, add text-align:center
to its parent.

. You can now pick a new encoding for that file.
Alternatively, you can change the setting globally in Workspace/User settings using the setting "files.encoding": "utf8"
. If using the graphical settings page in VSCode, simply search for encoding
. Do note however that this only applies to newly created files.
Try this ,
<img src= "@Url.Content(Model.ImagePath)" alt="Sample Image" style="height:50px;width:100px;"/>
(or)
<img src="~/Content/img/@Url.Content(model =>model.ImagePath)" style="height:50px;width:100px;"/>
Try this:
myfile %>% mutate(V5 = (V1 == 1 & V2 != 4) + 2 * (V2 == 4 & V3 != 1))
giving:
V1 V2 V3 V4 V5
1 1 2 3 5 1
2 2 4 4 1 2
3 1 4 1 1 0
4 4 5 1 3 0
5 5 5 5 4 0
or this:
myfile %>% mutate(V5 = ifelse(V1 == 1 & V2 != 4, 1, ifelse(V2 == 4 & V3 != 1, 2, 0)))
giving:
V1 V2 V3 V4 V5
1 1 2 3 5 1
2 2 4 4 1 2
3 1 4 1 1 0
4 4 5 1 3 0
5 5 5 5 4 0
Suggest you get a better name for your data frame. myfile makes it seem as if it holds a file name.
Above used this input:
myfile <-
structure(list(V1 = c(1L, 2L, 1L, 4L, 5L), V2 = c(2L, 4L, 4L,
5L, 5L), V3 = c(3L, 4L, 1L, 1L, 5L), V4 = c(5L, 1L, 1L, 3L, 4L
)), .Names = c("V1", "V2", "V3", "V4"), class = "data.frame", row.names = c("1",
"2", "3", "4", "5"))
Update 1 Since originally posted dplyr has changed %.%
to %>%
so have modified answer accordingly.
Update 2 dplyr now has case_when
which provides another solution:
myfile %>%
mutate(V5 = case_when(V1 == 1 & V2 != 4 ~ 1,
V2 == 4 & V3 != 1 ~ 2,
TRUE ~ 0))
Here is a really easy way of doing it:https://github.com/JagCesar/iOS-blur
Just copy the layer of UIToolbar and you're done, AMBlurView does it for you. Okay, it's not as blurry as control center, but is's blurry enough.
Remember that iOS7 is under NDA.
this solution from this link helped me a lot. you can check it out.
The curl.php file with those line of instruction can work.
<?php
// Server key from Firebase Console define( 'API_ACCESS_KEY', 'AAAA----FE6F' );
$data = array("to" => "cNf2---6Vs9", "notification" => array( "title" => "Shareurcodes.com", "body" => "A Code Sharing Blog!","icon" => "icon.png", "click_action" => "http://shareurcodes.com"));
$data_string = json_encode($data);
echo "The Json Data : ".$data_string;
$headers = array ( 'Authorization: key=' . API_ACCESS_KEY, 'Content-Type: application/json' );
$ch = curl_init(); curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_POSTFIELDS, $data_string);
$result = curl_exec($ch);
curl_close ($ch);
echo "<p> </p>";
echo "The Result : ".$result;
Remember you need to execute curl.php file using another browser ie not from the browser that is used to get the user token. You can see notification only if you are browsing another website.
Git is a revision control system, a tool to manage your source code history.
GitHub is a hosting service for Git repositories.
So they are not the same thing: Git is the tool, GitHub is the service for projects that use Git.
To get your code to GitHub, have a look here.
This is an example of dynamically added field. Here form data will store by input name key using React useState hook.

You haven't really said much about what sort of random string you need. But in any case, you should look into the random
module.
A very simple solution is pasted below.
import random
def randstring(length=10):
valid_letters='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
return ''.join((random.choice(valid_letters) for i in xrange(length)))
print randstring()
print randstring(20)
Based on some of the answers here, I have written a CustomConstructorResolver
for use in a current project, and I thought it might help somebody else.
It supports the following resolution mechanisms, all configurable:
Newtonsoft.Json.JsonConstructorAttribute
.public class CustomConstructorResolver : DefaultContractResolver
{
public string ConstructorAttributeName { get; set; } = "JsonConstructorAttribute";
public bool IgnoreAttributeConstructor { get; set; } = false;
public bool IgnoreSinglePrivateConstructor { get; set; } = false;
public bool IgnoreMostSpecificConstructor { get; set; } = false;
protected override JsonObjectContract CreateObjectContract(Type objectType)
{
var contract = base.CreateObjectContract(objectType);
// Use default contract for non-object types.
if (objectType.IsPrimitive || objectType.IsEnum) return contract;
// Look for constructor with attribute first, then single private, then most specific.
var overrideConstructor =
(this.IgnoreAttributeConstructor ? null : GetAttributeConstructor(objectType))
?? (this.IgnoreSinglePrivateConstructor ? null : GetSinglePrivateConstructor(objectType))
?? (this.IgnoreMostSpecificConstructor ? null : GetMostSpecificConstructor(objectType));
// Set override constructor if found, otherwise use default contract.
if (overrideConstructor != null)
{
SetOverrideCreator(contract, overrideConstructor);
}
return contract;
}
private void SetOverrideCreator(JsonObjectContract contract, ConstructorInfo attributeConstructor)
{
contract.OverrideCreator = CreateParameterizedConstructor(attributeConstructor);
contract.CreatorParameters.Clear();
foreach (var constructorParameter in base.CreateConstructorParameters(attributeConstructor, contract.Properties))
{
contract.CreatorParameters.Add(constructorParameter);
}
}
private ObjectConstructor<object> CreateParameterizedConstructor(MethodBase method)
{
var c = method as ConstructorInfo;
if (c != null)
return a => c.Invoke(a);
return a => method.Invoke(null, a);
}
protected virtual ConstructorInfo GetAttributeConstructor(Type objectType)
{
var constructors = objectType
.GetConstructors(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
.Where(c => c.GetCustomAttributes().Any(a => a.GetType().Name == this.ConstructorAttributeName)).ToList();
if (constructors.Count == 1) return constructors[0];
if (constructors.Count > 1)
throw new JsonException($"Multiple constructors with a {this.ConstructorAttributeName}.");
return null;
}
protected virtual ConstructorInfo GetSinglePrivateConstructor(Type objectType)
{
var constructors = objectType
.GetConstructors(BindingFlags.Instance | BindingFlags.NonPublic);
return constructors.Length == 1 ? constructors[0] : null;
}
protected virtual ConstructorInfo GetMostSpecificConstructor(Type objectType)
{
var constructors = objectType
.GetConstructors(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
.OrderBy(e => e.GetParameters().Length);
var mostSpecific = constructors.LastOrDefault();
return mostSpecific;
}
}

Feedback appreciated.
The same problem. If these methods not work. you can try to delete the lib from local maven repository, and reimport to pom .
Finally it' fine for me.
You could just use normal Python argument passing syntax to specify your crontab. For example, suppose we define an Event class as below:
from datetime import datetime, timedelta
import time
# Some utility classes / functions first
class AllMatch(set):
"""Universal set - match everything"""
def __contains__(self, item): return True
allMatch = AllMatch()
def conv_to_set(obj): # Allow single integer to be provided
if isinstance(obj, (int,long)):
return set([obj]) # Single item
if not isinstance(obj, set):
obj = set(obj)
return obj
# The actual Event class
class Event(object):
def __init__(self, action, min=allMatch, hour=allMatch,
day=allMatch, month=allMatch, dow=allMatch,
args=(), kwargs={}):
self.mins = conv_to_set(min)
self.hours= conv_to_set(hour)
self.days = conv_to_set(day)
self.months = conv_to_set(month)
self.dow = conv_to_set(dow)
self.action = action
self.args = args
self.kwargs = kwargs
def matchtime(self, t):
"""Return True if this event should trigger at the specified datetime"""
return ((t.minute in self.mins) and
(t.hour in self.hours) and
(t.day in self.days) and
(t.month in self.months) and
(t.weekday() in self.dow))
def check(self, t):
if self.matchtime(t):
self.action(*self.args, **self.kwargs)
(Note: Not thoroughly tested)
Then your CronTab can be specified in normal python syntax as:
c = CronTab(
Event(perform_backup, 0, 2, dow=6 ),
Event(purge_temps, 0, range(9,18,2), dow=range(0,5))
)
This way you get the full power of Python's argument mechanics (mixing positional and keyword args, and can use symbolic names for names of weeks and months)
The CronTab class would be defined as simply sleeping in minute increments, and calling check() on each event. (There are probably some subtleties with daylight savings time / timezones to be wary of though). Here's a quick implementation:
class CronTab(object):
def __init__(self, *events):
self.events = events
def run(self):
t=datetime(*datetime.now().timetuple()[:5])
while 1:
for e in self.events:
e.check(t)
t += timedelta(minutes=1)
while datetime.now() < t:
time.sleep((t - datetime.now()).seconds)
A few things to note: Python's weekdays / months are zero indexed (unlike cron), and that range excludes the last element, hence syntax like "1-5" becomes range(0,5) - ie [0,1,2,3,4]. If you prefer cron syntax, parsing it shouldn't be too difficult however.
try this, applies only to iPhone and iPod so you're not making everything turn blue on chrome or firefox mobile;
/iP/i.test(navigator.userAgent) && $('*').css('cursor', 'pointer');
basically, on iOS, things aren't "clickable" by default -- they're "touchable" (pfffff) so you make them "clickable" by giving them a pointer cursor. makes total sense, right??
The above postings helped in resolving my problem. In addition to the above I had to make the following changes to make it work :
Modified Maven's JRE net settings(\jre\lib\net.properties) to use system proxy setting.
https.proxyHost=proxy DNS
https.proxyPort=proxy port
Included proxy server settings in settings.xml. I did not provide username and password settings as to use NTLM authentication.
<context:property-placeholder ... />
is the XML equivalent to the PropertyPlaceholderConfigurer. So, prefer that. The <util:properties/>
simply factories a java.util.Properties instance that you can inject.
In Spring 3.1 (not 3.0...) you can do something like this:
@Configuration
@PropertySource("/foo/bar/services.properties")
public class ServiceConfiguration {
@Autowired Environment environment;
@Bean public javax.sql.DataSource dataSource( ){
String user = this.environment.getProperty("ds.user");
...
}
}
In Spring 3.0, you can "access" properties defined using the PropertyPlaceHolderConfigurer mechanism using the SpEl annotations:
@Value("${ds.user}") private String user;
If you want to remove the XML all together, simply register the PropertyPlaceholderConfigurer manually using Java configuration. I prefer the 3.1 approach. But, if youre using the Spring 3.0 approach (since 3.1's not GA yet...), you can now define the above XML like this:
@Configuration
public class MySpring3Configuration {
@Bean
public static PropertyPlaceholderConfigurer configurer() {
PropertyPlaceholderConfigurer ppc = ...
ppc.setLocations(...);
return ppc;
}
@Bean
public class DataSource dataSource(
@Value("${ds.user}") String user,
@Value("${ds.pw}") String pw,
...) {
DataSource ds = ...
ds.setUser(user);
ds.setPassword(pw);
...
return ds;
}
}
Note that the PPC is defined using a static
bean definition method. This is required to make sure the bean is registered early, because the PPC is a BeanFactoryPostProcessor
- it can influence the registration of the beans themselves in the context, so it necessarily has to be registered before everything else.
I have python 2.73 and windows 7 .The solution that worked for me was:
C:\programs\mingw\bin;
Created distutils.cfg located at C:\Python27\Lib\distutils\distutils.cfg
containing:
[build]
compiler=mingw32
To deal with MinGW not recognizing the -mno-cygwin flag anymore, remove the flag in C:\Python27\Lib\distutils\cygwincompiler.py line 322 to 326, so it looks like this:
self.set_executables(compiler='gcc -O -Wall',
compiler_so='gcc -mdll -O -Wall',
compiler_cxx='g++ -O -Wall',
linker_exe='gcc',
linker_so='%s %s %s'
% (self.linker_dll, shared_option,
entry_point))
Go to the page from where you want to access the App_code class, and then add the namespace of the app_code class. You need to provide a using
statement, as follows:
using WebApplication3.App_Code;
After that, you will need to go to the app_code class property and set the 'Build Action' to 'Compile'.
For Azure Functions we use this simple extension to Microsoft.Extensions.Logging.ILogger
public static class LoggerExtensions
{
public static void Error(this ILogger logger, string message, Exception exception)
{
if (exception is DbEntityValidationException dbException)
{
message += "\nValidation Errors: ";
foreach (var error in dbException.EntityValidationErrors.SelectMany(entity => entity.ValidationErrors))
{
message += $"\n * Field name: {error.PropertyName}, Error message: {error.ErrorMessage}";
}
}
logger.LogError(default(EventId), exception, message);
}
}
and example usage:
try
{
do something with request and EF
}
catch (Exception e)
{
log.Error($"Failed to create customer due to an exception: {e.Message}", e);
return await StringResponseUtil.CreateResponse(HttpStatusCode.InternalServerError, e.Message);
}
Use Calendar.
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
cal.set(Calendar.HOUR, cal.get(Calendar.HOUR) - 1);
