Also worth to mention, that when partial function passed another function where we want to "hard code" some parameters, that should be rightmost parameter
def func(a,b):
return a*b
prt = partial(func, b=7)
print(prt(4))
#return 28
but if we do the same, but changing a parameter instead
def func(a,b):
return a*b
prt = partial(func, a=7)
print(prt(4))
it will throw error, "TypeError: func() got multiple values for argument 'a'"
Those are non-printing characters, relating to the concept of "new line". \n is linefeed. \r is carriage return. On different platforms they have different meanings, relative to a valid new line. In windows, a new line is \r\n. In linux, \n. In mac, \r.
In practice, you put them in any string, and it will have effect on the print-out of the string.
I had a similar issue where I also continuously got the same error. I tried many things like changing the listener port number, turning off the firewall etc. Finally I was able to resolve the issue by changing listener.ora file. I changed the following line:
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
to
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
I also added an entry in the /etc/hosts
file.
you can use Oracle net manager to change the above line in listener.ora file. See Oracle Net Services Administrator's Guide for more information on how to do it using net manager.
Also you can use the service name (database_name.domain_name
) instead of SID while making the connnection.
I Hope it helps.
mkoryak
is correct.
But, if events are bound to that DOM node using more modern methods (not using onclick
), then this method will fail.
If that is what you really want, check out this question, and its accepted answer.
Cheers!
I read your question again.
I'd like to tell you this: don't use onclick
, onkeypress
and the likes to bind events.
Using better methods like addEventListener()
will enable you to:
Instead of actually using addEventListener()
, you could use jQuery
wrappers like $('selector').click()
.
Cheers again!
To exclude system databases:
SELECT [name]
FROM master.dbo.sysdatabases
WHERE dbid > 6
Edited : 2:36 PM 2/5/2013
Updated with accurate database_id, It should be greater than 4, to skip listing system databases which are having database id between 1 and 4.
SELECT *
FROM sys.databases d
WHERE d.database_id > 4
Enter the following command to insert data into the testlog table with some condition:

I found a new way to do it that is Emit.
We can use Emit to add the IL to app and run it. But I dont think its a good way for I want to perfect this that I write my answer.
The Emit can see the official document and Guide
You should learn some IL to read the code. I will write the code that can copy the property in class.
public static class Clone
{
// ReSharper disable once InconsistentNaming
public static void CloneObjectWithIL<T>(T source, T los)
{
//see http://lindexi.oschina.io/lindexi/post/C-%E4%BD%BF%E7%94%A8Emit%E6%B7%B1%E5%85%8B%E9%9A%86/
if (CachedIl.ContainsKey(typeof(T)))
{
((Action<T, T>) CachedIl[typeof(T)])(source, los);
return;
}
var dynamicMethod = new DynamicMethod("Clone", null, new[] { typeof(T), typeof(T) });
ILGenerator generator = dynamicMethod.GetILGenerator();
foreach (var temp in typeof(T).GetProperties().Where(temp => temp.CanRead && temp.CanWrite))
{
//do not copy static that will except
if (temp.GetAccessors(true)[0].IsStatic)
{
continue;
}
generator.Emit(OpCodes.Ldarg_1);// los
generator.Emit(OpCodes.Ldarg_0);// s
generator.Emit(OpCodes.Callvirt, temp.GetMethod);
generator.Emit(OpCodes.Callvirt, temp.SetMethod);
}
generator.Emit(OpCodes.Ret);
var clone = (Action<T, T>) dynamicMethod.CreateDelegate(typeof(Action<T, T>));
CachedIl[typeof(T)] = clone;
clone(source, los);
}
private static Dictionary<Type, Delegate> CachedIl { set; get; } = new Dictionary<Type, Delegate>();
}
The code can be deep copy but it can copy the property. If you want to make it to deep copy that you can change it for the IL is too hard that I cant do it.
Enums in TypeScript 0.9 are string+number based. You should not need type assertion for simple conversions:
enum Color{
Red, Green
}
// To String
var green: string = Color[Color.Green];
// To Enum / number
var color : Color = Color[green];
I have documention about this and other Enum patterns in my OSS book : https://basarat.gitbook.io/typescript/type-system/enums
Many people have answered the mechanical details already, but it's worth noting: This is a poor design choice, by Java.
Java's asList
method is documented as "Returns a fixed-size list...". If you take its result and call (say) the .add
method, it throws an UnsupportedOperationException
. This is unintuitive behavior! If a method says it returns a List
, the standard expectation is that it returns an object which supports the methods of interface List
. A developer shouldn't have to memorize which of the umpteen util.List
methods create List
s that don't actually support all the List
methods.
If they had named the method asImmutableList
, it would make sense. Or if they just had the method return an actual List
(and copy the backing array), it would make sense. They decided to favor both runtime-performance and short names, at the expense of violating both the Principle of Least Surprise and the good-O.O. practice of avoiding UnsupportedOperationException
s.
(Also, the designers might have made a interface ImmutableList
, to avoid a plethora of UnsupportedOperationException
s.)
Microsoft .NET framework 3.5 can be installed on windows 10 without having installation media. The file you need is called microsoft-windows-netfx3-ondemand-package.cab
. Just google it and you will get the download links.
After downloading it, copy that file to C:\dotnet35
and run the following command.
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess
Tested and worked in Windows 10 without any issue.
pg_config is for compliation information, to help extensions and client programs compile and link against PostgreSQL. It knows nothing about the active PostgreSQL instance(s) on the machine, only the binaries.
pg_hba.conf can appear in many other places depending on how Pg was installed. The standard location is pg_hba.conf within the data_directory of the database (which could be in /home, /var/lib/pgsql, /var/lib/postgresql/[version]/, /opt/postgres/, etc etc etc) but users and packagers can put it wherever they like. Unfortunately.
The only valid ways find pg_hba.conf is to ask a running PostgreSQL instance where it's pg_hba.conf is, or ask the sysadmin where it is. You can't even rely on asking where the datadir is and parsing postgresql.conf because an init script might passed a param like -c hba_file=/some/other/path when starting Pg.
What you want to do is ask PostgreSQL:
SHOW hba_file;
This command must be run on a superuser session, so for shell scripting you might write something like:
psql -t -P format=unaligned -c 'show hba_file';
and set the environment variables PGUSER, PGDATABASE, etc to ensure that the connection is right.
Yes, this is somewhat of a chicken-and-egg problem, in that if the user can't connect (say, after screwing up editing pg_hba.conf) you can't find pg_hba.conf in order to fix it.
Another option is to look at the ps command's output and see if the postmaster data directory argument -D is visible there, e.g.
ps aux | grep 'postgres *-D'
since pg_hba.conf will be inside the data directory (unless you're on Debian/Ubuntu or some derivative and using their packages).
If you're targeting specifically Ubuntu systems with PostgreSQL installed from Debian/Ubuntu packages it gets a little easier. You don't have to deal with hand-compiled-from-source Pg that someone's initdb'd a datadir for in their home dir, or an EnterpriseDB Pg install in /opt, etc. You can ask pg_wrapper, the Debian/Ubuntu multi-version Pg manager, where PostgreSQL is using the pg_lsclusters command from pg_wrapper.
If you can't connect (Pg isn't running, or you need to edit pg_hba.conf to connect) you'll have to search the system for pg_hba.conf files. On Mac and Linux something like sudo find / -type f -name pg_hba.conf will do. Then check the PG_VERSION file in the same directory to make sure it's the right PostgreSQL version if you have more than one. (If pg_hba.conf is in /etc/, ignore this, it's the parent directory name instead). If you have more than one data directory for the same PostgreSQL version you'll have to look at database size, check the command line of the running postgres from ps to see if it's data directory -D argument matches where you're editing, etc. https://askubuntu.com/questions/256534/how-do-i-find-the-path-to-pg-hba-conf-from-the-shell/256711
Create = PUT with a new URI
POST to a base URI returning a newly created URI
Read = GET
Update = PUT with an existing URI
Delete = DELETE
PUT can map to both Create and Update depending on the existence of the URI used with the PUT.
POST maps to Create.
Correction: POST can also map to Update although it's typically used for Create. POST can also be a partial update so we don't need the proposed PATCH method.
Actually, it is worth noticing that git merge --abort
is only equivalent to git reset --merge
given that MERGE_HEAD
is present. This can be read in the git help for merge command.
git merge --abort # is equivalent to git reset --merge when MERGE_HEAD is present.
After a failed merge, when there is no MERGE_HEAD
, the failed merge can be undone with git reset --merge
but not necessarily with git merge --abort
, so they are not only old and new syntax for the same thing.
Personally I find git reset --merge
much more useful in everyday work.
The binary version of ABC123EFFF is actually 1010101111000001001000111110111111111111
For almost all applications you want the binary version to have a length that is a multiple of 4 with leading padding of 0s.
To get this in Python:
def hex_to_binary( hex_code ):
bin_code = bin( hex_code )[2:]
padding = (4-len(bin_code)%4)%4
return '0'*padding + bin_code
Example 1:
>>> hex_to_binary( 0xABC123EFFF )
'1010101111000001001000111110111111111111'
Example 2:
>>> hex_to_binary( 0x7123 )
'0111000100100011'
Note that this also works in Micropython :)
h2 { display: inline }
You can also achieve this by using following SQL with date and hour in same columns and proper date time format and ordered by date time
SELECT dateadd(hour, datediff(hour, 0, StartDate), 0) as 'ForDate',
COUNT(*) as 'Count'
FROM #Events
GROUP BY dateadd(hour, datediff(hour, 0, LogTime), 0)
ORDER BY ForDate
f-string formatting:
This was new in Python 3.6 - the string is placed in quotation marks as usual, prepended with f'...
in the same way you would r'...
for a raw string. Then you place whatever you want to put within your string, variables, numbers, inside braces f'some string text with a {variable} or {number} within that text'
- and Python evaluates as with previous string formatting methods, except that this method is much more readable.
>>> foobar = 3.141592
>>> print(f'My number is {foobar:.2f} - look at the nice rounding!')
My number is 3.14 - look at the nice rounding!
You can see in this example we format with decimal places in similar fashion to previous string formatting methods.
NB foobar
can be an number, variable, or even an expression eg f'{3*my_func(3.14):02f}'
.
Going forward, with new code I prefer f-strings over common %s or str.format() methods as f-strings can be far more readable, and are often much faster.
If you want to use straight PowerShell check out the below code.

Okay I fixed this thing. Had to first convert the projects to Maven Projects, then remove them from the Eclipse workspace, and then re-import them.
I took every possibilities I had in mind to do it with pure ruby code, here they are :
capitalize and gsub
'app_user'.capitalize.gsub(/_(\w)/){$1.upcase}
split and map using &
shorthand (thanks to user3869936’s answer)
'app_user'.split('_').map(&:capitalize).join
split and map (thanks to Mr. Black’s answer)
'app_user'.split('_').map{|e| e.capitalize}.join
And here is the Benchmark for all of these, we can see that gsub is quite bad for this. I used 126 080 words.
user system total real
capitalize and gsub : 0.360000 0.000000 0.360000 ( 0.357472)
split and map, with &: 0.190000 0.000000 0.190000 ( 0.189493)
split and map : 0.170000 0.000000 0.170000 ( 0.171859)
The easy solution is to write something like that,
px-lg-1
mb-lg-5
By adding lg, the class will be applied only on large screens
Starting with MySQL 8 you no longer can (implicitly) create a user using the GRANT
command. Use CREATE USER instead, followed by the GRANT statement:
mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'root';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
Caution about the security risks about WITH GRANT OPTION
, see:
SELECT MONTHNAME(t.summaryDateTime) as month, YEAR(t.summaryDateTime) as year
FROM trading_summary t
GROUP BY YEAR(t.summaryDateTime) DESC, MONTH(t.summaryDateTime) DESC
Should use DESC for both YEAR and Month to get correct order.
Most people use docker compose with networks. The documentation states:
The Docker network feature supports creating networks without the need to expose ports within the network, for detailed information see the overview of this feature).
Which means that if you use networks for communication between containers you don't need to worry about exposing ports.
nsenter
does that. However I also needed to enter a container in a simple way and nsenter didn't suffice for my needs. It was buggy in some occasions (black screen plus -wd flag not working). Furthermore I wanted to login as a specific user and in a specific directory.
I ended up making my own tool to enter containers. You can find it at: https://github.com/Pithikos/docker-enter
Its usage is as easy as
./docker-enter [-u <user>] [-d <directory>] <container ID>
At first, you must specify your path, the path that your *.csv
files are in there
path = 'f:\project\dataset'
You can change it based on your system.
then,
use dir
function :
files = dir (strcat(path,'\*.csv'))
L = length (files);
for i=1:L
image{i}=csvread(strcat(path,'\',file(i).name));
% process the image in here
end
pwd
also can be used.
Simply add the disabled class to the button instead of the disabled attribute to make it visibly disabled instead.
<button class="btn disabled" rel="tooltip" data-title="Dieser Link führt zu Google">button disabled</button>
Note: this button only appears to be disabled, but it still triggers events, and you just have to be mindful of that.
Some code that allows you to use CI instance inside the helper:
function yourHelperFunction(){
$ci=& get_instance();
$ci->load->database();
$sql = "select * from table";
$query = $ci->db->query($sql);
$row = $query->result();
}
If you want to search for these invisible characters in your editor and make them visible, you can use a Regular Expression searching for non-ascii characters.
Try searching for [^\x00-\x7F]

window.location.hash = 'something';
That is just plain JavaScript.
Your comment...
Hi, what I really need is to add only the hash... something like this:
window.location.hash = '#';
but in this way nothing is added.
Try this...
window.location = '#';
Also, don't forget about the window.location.replace()
method.
Although this is not exactly what OP meant as this is not super simple, however, when running scripts from Notepad++ the os.getcwd()
method doesn't work as expected. This is what I would do:
import os
# get real current directory (determined by the file location)
curDir, _ = os.path.split(os.path.abspath(__file__))
print(curDir) # print current directory
Define a function like this:
def dir_up(path,n): # here 'path' is your path, 'n' is number of dirs up you want to go
for _ in range(n):
path = dir_up(path.rpartition("\\")[0], 0) # second argument equal '0' ensures that
# the function iterates proper number of times
return(path)
The use of this function is fairly simple - all you need is your path and number of directories up.
print(dir_up(curDir,3)) # print 3 directories above the current one
The only minus is that it doesn't stop on drive letter, it just will show you empty string.
If you want to get unique elements from a list and keep their original order, then you may employ OrderedDict
data structure from Python's standard library:
from collections import OrderedDict
def keep_unique(elements):
return list(OrderedDict.fromkeys(elements).keys())
elements = [2, 1, 4, 2, 1, 1, 5, 3, 1, 1]
required_output = [2, 1, 4, 5, 3]
assert keep_unique(elements) == required_output
In fact, if you are using Python = 3.6, you can use plain dict
for that:
def keep_unique(elements):
return list(dict.fromkeys(elements).keys())
It's become possible after the introduction of "compact" representation of dicts. Check it out here. Though this "considered an implementation detail and should not be relied upon".
You can also clear the field before sending it keys.
element.clear()
element.sendKeys("Some text here")
You can use the parseInt() function to convert the string to a number, e.g:
parseInt($('#elem').css('top'));
Update: (as suggested by Ben): You should give the radix too:
parseInt($('#elem').css('top'), 10);
Forces it to be parsed as a decimal number, otherwise strings beginning with '0' might be parsed as an octal number (might depend on the browser used).
It means it's a decimal literal, as others have said. However, the origins are probably not those suggested elsewhere in this answer. From the C# Annotated Standard (the ECMA version, not the MS version):
The
decimal
suffix is M/m since D/d was already taken bydouble
. Although it has been suggested that M stands for money, Peter Golde recalls that M was chosen simply as the next best letter indecimal
.
A similar annotation mentions that early versions of C# included "Y" and "S" for byte
and short
literals respectively. They were dropped on the grounds of not being useful very often.
Stored procedure is the best way to do it. Because Meherzad's solution would work only if the data follows the same order.
If we have a table structure like this
col1 | col2 | col3
-----+------+------
3 | k | 7
5 | d | 3
1 | a | 5
6 | o | 2
2 | 0 | 8
It wont work. SQL Fiddle Demo

Wikibooks has a fairly good summary of jump instructions. Basically, there's actually two stages:
cmp_instruction op1, op2
Which sets various flags based on the result, and
jmp_conditional_instruction address
which will execute the jump based on the results of those flags.
Compare (cmp
) will basically compute the subtraction op1-op2
, however, this is not stored; instead only flag results are set. So if you did cmp eax, ebx
that's the same as saying eax-ebx
- then deciding based on whether that is positive, negative or zero which flags to set.

To delete a cookie I set it again with an empty value and expiring in 1 second. In details, I always use one of the following flavours (I tend to prefer the second one):
1.
function setCookie(key, value, expireDays, expireHours, expireMinutes, expireSeconds) {
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = key +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie(name, "", null , null , null, 1);
}
Usage:
setCookie("reminder", "buyCoffee", null, null, 20);
deleteCookie("reminder");
2
function setCookie(params) {
var name = params.name,
value = params.value,
expireDays = params.days,
expireHours = params.hours,
expireMinutes = params.minutes,
expireSeconds = params.seconds;
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = name +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie({name: name, value: "", seconds: 1});
}
Usage:
setCookie({name: "reminder", value: "buyCoffee", minutes: 20});
deleteCookie("reminder");
The only need to use the this.

There are several representations of newlines, see http://en.wikipedia.org/wiki/Newline#Representations
Just to be really clear, this has nothing to do with enumerate
and everything to do with list comprehension syntax.
This list comprehension returns a list of tuples:
[(i,j) for i in range(3) for j in 'abc']
this a list of dicts:
[{i:j} for i in range(3) for j in 'abc']
a list of lists:
[[i,j] for i in range(3) for j in 'abc']
a syntax error:
[i,j for i in range(3) for j in 'abc']
Which is inconsistent (IMHO) and confusing with dictionary comprehensions syntax:
>>> {i:j for i,j in enumerate('abcdef')}
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f'}
And a set of tuples:
>>> {(i,j) for i,j in enumerate('abcdef')}
set([(0, 'a'), (4, 'e'), (1, 'b'), (2, 'c'), (5, 'f'), (3, 'd')])
As Óscar López stated, you can just pass the enumerate tuple directly:
>>> [t for t in enumerate('abcdef') ]
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f')]
Try using the COLUMN command with the FORMAT option for that:

The Oracle JDeveloper 11g built-in viewer is in my view superior to the one available for Eclipse (which, in addition to other unfavourable comparison points I could only get to install for Indigo but not for Juno).

Not really sure why a simple answer, that delivers the desired results, gets me a negative mark.
In JavaScript, \w and \d are ASCII, while \s is Unicode. Don't ask me why. JavaScript does support \p with Unicode categories, which you can use to emulate a Unicode-aware \w and \d.
For \d use \p{N} (numbers)
For \w use [\p{L}\p{N}\p{Pc}\p{M}] (letters, numbers, underscores, marks)
Update: Unfortunately, I was wrong about this. JavaScript does does not officially support \p either, though some implementations may still support this. The only Unicode support in JavaScript regexes is matching specific code points with \uFFFF. You can use those in ranges in character classes.

If you want to take out the mail from a long string or file Then try this.
([^@|\s]+@[^@]+\.[^@|\s]+)
Note, this will work when you have a space before and after your email-address. if you don't have space or have some special chars then you may try modifying it.
Working example:
string="Hello ABCD, here is my mail id [email protected] "
res = re.search("([^@|\s]+@[^@]+\.[^@|\s]+)",string,re.I)
res.group(1)
This will take out [email protected]
from this string.
Also, note this may not be the right answer... But I have posted it here to help someone who has specific requirement like me
Multi-dimension arrays are (n-1)-dimension matrices.
So int[,] square = new int[2,2]
is square matrix 2x2, int[,,] cube = new int [3,3,3]
is a cube - square matrix 3x3. Proportionality is not required.
Jagged arrays are just array of arrays - an array where each cell contains an array.
So MDA are proportional, JD may be not! Each cell can contains an array of arbitrary length!
The selected answer didn't quite work for me as I had to tap the EditText box once, and then tap it again before the OnClickListener would fire. I was able to fix this by replacing OnClickListener with OnTouchListener, just in case anyone has run into a similar issue here is what my code looks like:
Calendar myCalendar = Calendar.getInstance();
DatePickerDialog.OnDateSetListener date = new
DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
edittext.setOnTouchListener(new View.OnTouchListener() {
@Override
public void onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
new DatePickerDialog(classname.this, date, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
}
});

if you do not want to create a custom class loader. You can read the jar file stream. And transfer it to a File object. Then you can get the url of the File. Send it to the URLClassLoader, you can load the jar file as you want. sample:
InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("example"+ ".jar");
final File tempFile = File.createTempFile("temp", ".jar");
tempFile.deleteOnExit(); // you can delete the temp file or not
try (FileOutputStream out = new FileOutputStream(tempFile)) {
IOUtils.copy(resourceAsStream, out);
}

It depends on the database to which you're trying to connect, the method by which you created the connection, and the version of Excel that you're using. (Also, most probably, the version of the relevant ODBC driver on your computer.)
The following examples are using SQL Server 2008 and Excel 2007, both on my local machine.
When I used the Data Connection Wizard (on the Data tab of the ribbon, in the Get External Data section, under From Other Sources), I saw the same thing that you did: the Parameters button was disabled, and adding a parameter to the query, something like select field from table where field2 = ?
, caused Excel to complain that the value for the parameter had not been specified, and the changes were not saved.
When I used Microsoft Query (same place as the Data Connection Wizard), I was able to create parameters, specify a display name for them, and enter values each time the query was run. Bringing up the Connection Properties for that connection, the Parameters... button is enabled, and the parameters can be modified and used as I think you want.
I was also able to do this with an Access database. It seems reasonable that Microsoft Query could be used to create parameterized queries hitting other types of databases, but I can't easily test that right now.
I've always known it as kebab-case
.
On a funny note, I've heard people call it a SCREAM-KEBAB
when all the letters are capitalized.
I've always liked kebab-case
as it seems the most readable when you need whitespace. However, some programs interpret the dash as a minus sign, and it can cause problems as what you think is a name turns into a subtraction operation.
first-second // first minus second?
ten-2 // ten minus two?
Also, some frameworks parse dashes in kebab cased property. For example, GitHub Pages uses Jekyll, and Jekyll parses any dashes it finds in an md file. For example, a file named 2020-1-2-homepage.md
on GitHub Pages gets put into a folder structured as \2020\1\2\homepage.html
when the site is compiled.
A safer alternative to kebab-case
is snake_case
, or SCREAMING_SNAKE_CAS
E, as underscores cause less confusion when compared to a minus sign.
Firstly remove duplicates:
arrayList1.removeAll(arrayList2);
Then merge two arrayList:
arrayList1.addAll(arrayList2);
Lastly, sort your arrayList if you wish:
collections.sort(arrayList1);
In case you don't want to make any changes on the existing list, first create their backup lists:
arrayList1Backup = new ArrayList(arrayList1);
Looks like it varies depending on what compiler you're using (blech):
%zu
(or %zx
, or %zd
but that displays it as though it were signed, etc.)%Iu
(or %Ix
, or %Id
but again that's signed, etc.) — but as of cl v19 (in Visual Studio 2015), Microsoft supports %zu
(see this reply to this comment)...and of course, if you're using C++, you can use cout
instead as suggested by AraK.
This is found in the documentation. With a library like moment, I urge you to read the entirety of the documentation. It's really important.
Assuming the input text is entered in terms of the users's local time:
var expires = moment(date).valueOf();
If the user is instructed actually enter a UTC date/time, then:
var expires = moment.utc(date).valueOf();
The most easiest way would be to use unfactor
function from package varhandle which can accept a factor vector or even a dataframe:
unfactor(your_factor_variable)
This example can be a quick start:
x <- rep(c("a", "b", "c"), 20)
y <- rep(c(1, 1, 0), 20)
class(x) # -> "character"
class(y) # -> "numeric"
x <- factor(x)
y <- factor(y)
class(x) # -> "factor"
class(y) # -> "factor"
library(varhandle)
x <- unfactor(x)
y <- unfactor(y)
class(x) # -> "character"
class(y) # -> "numeric"
You can also use it on a dataframe. For example the iris
dataset:
sapply(iris, class)
Sepal.Length Sepal.Width Petal.Length Petal.Width Species "numeric" "numeric" "numeric" "numeric" "factor"
# load the package
library("varhandle")
# pass the iris to unfactor
tmp_iris <- unfactor(iris)
# check the classes of the columns
sapply(tmp_iris, class)
Sepal.Length Sepal.Width Petal.Length Petal.Width Species "numeric" "numeric" "numeric" "numeric" "character"
# check if the last column is correctly converted
tmp_iris$Species
[1] "setosa" "setosa" "setosa" "setosa" "setosa" [6] "setosa" "setosa" "setosa" "setosa" "setosa" [11] "setosa" "setosa" "setosa" "setosa" "setosa" [16] "setosa" "setosa" "setosa" "setosa" "setosa" [21] "setosa" "setosa" "setosa" "setosa" "setosa" [26] "setosa" "setosa" "setosa" "setosa" "setosa" [31] "setosa" "setosa" "setosa" "setosa" "setosa" [36] "setosa" "setosa" "setosa" "setosa" "setosa" [41] "setosa" "setosa" "setosa" "setosa" "setosa" [46] "setosa" "setosa" "setosa" "setosa" "setosa" [51] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [56] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [61] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [66] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [71] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [76] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [81] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [86] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [91] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [96] "versicolor" "versicolor" "versicolor" "versicolor" "versicolor" [101] "virginica" "virginica" "virginica" "virginica" "virginica" [106] "virginica" "virginica" "virginica" "virginica" "virginica" [111] "virginica" "virginica" "virginica" "virginica" "virginica" [116] "virginica" "virginica" "virginica" "virginica" "virginica" [121] "virginica" "virginica" "virginica" "virginica" "virginica" [126] "virginica" "virginica" "virginica" "virginica" "virginica" [131] "virginica" "virginica" "virginica" "virginica" "virginica" [136] "virginica" "virginica" "virginica" "virginica" "virginica" [141] "virginica" "virginica" "virginica" "virginica" "virginica" [146] "virginica" "virginica" "virginica" "virginica" "virginica"

How about sys.exit()
from the module sys
.
If sys.exit()
is executed from within a thread it will close that thread only.
This answer here talks about that: Why does sys.exit() not exit when called inside a thread in Python?

The Entry created and returned by the Collection might not match the Entry POSTed by the client. A server MAY change the values of various elements in the Entry, such as the atom:id, atom:updated, and atom:author values, and MAY choose to remove or add other elements and attributes, or change element content and attribute values.
Say your variable is myNode

This is great to use but remember that it comes in as a string and will need iterated through.
Looks like you called it 'ant build..xml'. ant automatically choose a file build.xml in the current directory, so it is enough to call 'ant' (if a default-target is defined) or 'ant target' (the target named target will be called).
With the call 'ant -p' you get a list of targets defined in your build.xml.
Edit: In the comment is shown the call 'ant -verbose build.xml'. To be correct, this has to be called as 'ant -verbose'. The file build.xml in the current directory will be used automatically. If it is needed to explicitly specify the buildfile (because it's name isn't build.xml for example), you have to specify the buildfile with the '-f'-option: 'ant -verbose -f build.xml'. I hope this helps.

java.sql.SQLException: No suitable driver found for jdbc:derby://localhost:1527/
This exception has two causes:
In your case, I'd expect to see a database name at the end of the connection string. For example (use create=true
if you want the database to be created if it doesn't exist):
jdbc:derby://localhost:1527/dbname;create=true
Databases are created by default in the directory where the Network Server was started up. But you can also specify an absolute path to the database location:
jdbc:derby://localhost:1527//home/pascal/derbyDBs/dbname;create=true
And just in case, check that derbyclient.jar is on the class path and that you are loading the appropriate driver org.apache.derby.jdbc.ClientDriver
when working in server mode.
It is simple.

Chris Fulstow's solution will work (+1), however, it may not be efficient, especially if your collection is very large. Non-rooted regular expressions (those not beginning with ^
, which anchors the regular expression to the start of the string), and those using the i
flag for case insensitivity will not use indexes, even if they exist.
An alternative option you might consider is to denormalize your data to store a lower-case version of the name
field, for instance as name_lower
. You can then query that efficiently (especially if it is indexed) for case-insensitive exact matches like:
db.collection.find({"name_lower": thename.toLowerCase()})
Or with a prefix match (a rooted regular expression) as:
db.collection.find( {"name_lower":
{ $regex: new RegExp("^" + thename.toLowerCase(), "i") } }
);
Both of these queries will use an index on name_lower
.
Definitely avoid using eval
to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.
For example, if you were to use the eval
solutions proposed here, a nefarious user could send a link to their victim that looked like this:
http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}
And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.
So, make sure you never eval
untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:
// set up the possible functions:
var myFuncs = {
func1: function () { alert('Function 1'); },
func2: function () { alert('Function 2'); },
func3: function () { alert('Function 3'); },
func4: function () { alert('Function 4'); },
func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();
This will fail if the funcToRun
variable doesn't point to anything in the myFuncs
object, but it won't execute any code.
Or, you can clip the select. Something along the lines of:
select { width:200px; position:absolute; clip:rect(0, 170px, 50px, 0); }
This should clip 30px of the right side of select box, stripping away the arrow. Now supply a 170px background image and voila, styled select
This can be easily solved with the the utility make_axes_locatable
. I provide a minimal example that shows how this works and should be readily adaptable:
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np
m1 = np.random.rand(3, 3)
m2 = np.arange(0, 3*3, 1).reshape((3, 3))
fig = plt.figure(figsize=(16, 12))
ax1 = fig.add_subplot(121)
im1 = ax1.imshow(m1, interpolation='None')
divider = make_axes_locatable(ax1)
cax = divider.append_axes('right', size='5%', pad=0.05)
fig.colorbar(im1, cax=cax, orientation='vertical')
ax2 = fig.add_subplot(122)
im2 = ax2.imshow(m2, interpolation='None')
divider = make_axes_locatable(ax2)
cax = divider.append_axes('right', size='5%', pad=0.05)
fig.colorbar(im2, cax=cax, orientation='vertical');
The number of results can (theoretically) be greater than the range of an integer. I would refactor the code and work with the returned long value instead.
For windows set the default browser to open html files to Chrome. Configuration > Default Apps > Default Apps by File Type. Worked for me.
Use an NSDateFormatter to convert string1
into an NSDate
, then get the required NSDateComponents:
Obj-C:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"<your date format goes here"];
NSDate *date = [dateFormatter dateFromString:string1];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];
NSInteger hour = [components hour];
NSInteger minute = [components minute];
Swift 1 and 2:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "Your date Format"
let date = dateFormatter.dateFromString(string1)
let calendar = NSCalendar.currentCalendar()
let comp = calendar.components([.Hour, .Minute], fromDate: date)
let hour = comp.hour
let minute = comp.minute
Swift 3:
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "Your date Format"
let date = dateFormatter.date(from: string1)
let calendar = Calendar.current
let comp = calendar.dateComponents([.hour, .minute], from: date)
let hour = comp.hour
let minute = comp.minute
More about the dateformat is on the official unicode site
Why can't it be the onResume() is invoked after onRestart() and onCreate() methods just excluding onStart()? What is its purpose?
OK, as my first answer was pretty long I won't extend it further so let's try this...
public DriveToWorkActivity extends Activity
implements onReachedGroceryStoreListener {
}
public GroceryStoreActivity extends Activity {}
PLEASE NOTE: I've deliberately left out the calls to things like super.onCreate(...)
etc. This is pseudo-code so give me some artistic licence here. ;)
The methods for DriveToWorkActivity
follow...
protected void onCreate(...) {
openGarageDoor();
unlockCarAndGetIn();
closeCarDoorAndPutOnSeatBelt();
putKeyInIgnition();
}
protected void onStart() {
startEngine();
changeRadioStation();
switchOnLightsIfNeeded();
switchOnWipersIfNeeded();
}
protected void onResume() {
applyFootbrake();
releaseHandbrake();
putCarInGear();
drive();
}
protected void onPause() {
putCarInNeutral();
applyHandbrake();
}
protected void onStop() {
switchEveryThingOff();
turnOffEngine();
removeSeatBeltAndGetOutOfCar();
lockCar();
}
protected void onDestroy() {
enterOfficeBuilding();
}
protected void onReachedGroceryStore(...) {
Intent i = new Intent(ACTION_GET_GROCERIES, ..., this, GroceryStoreActivity.class);
}
protected void onRestart() {
unlockCarAndGetIn();
closeDoorAndPutOnSeatBelt();
putKeyInIgnition();
}
OK, so it's another long one (sorry folks). But here's my explanation...
onResume()
is when I start driving and onPause()
is when I come to a temporary stop. So I drive then reach a red light so I pause...the light goes green and I resume. Another red light and I pause, then green so I resume. The onPause() -> onResume() -> onPause() -> onResume()
loop is a tight one and occurs many times through my journey.
The loop from being stopped back through a restart (preparing to carry on my journey) to starting again is perhaps less common. In one case, I spot the Grocery Store and the GroceryStoreActivity
is started (forcing my DriveToWorkActivity
to the point of onStop()
). When I return from the store, I go through onRestart()
and onStart()
then resume my journey.
I could put the code that's in onStart()
into both onCreate()
and onRestart()
and not bother to override onStart()
at all but the more that needs to be done between onCreate() -> onResume()
and onRestart() -> onResume()
, the more I'm duplicating things.
So, to requote once more...
Why can't it be the onResume() is invoked after onRestart() and onCreate() methods just excluding onStart()?
If you don't override onStart()
then this is effectively what happens. Although the onStart()
method of Activity
will be called implicitly, the effect in your code is effectively onCreate() -> onResume()
or onRestart() -> onResume()
.
git reset --hard CommitId
git push -f origin master
1st command will rest your head to commitid and 2nd command will delete all commit after that commit id on master branch.
Note: Don't forget to add -f in push otherwise it will be rejected.
Declarations of public functions go in header files, yes, but definitions are absolutely valid in headers as well! You may declare the definition as static (only 1 copy allowed for the entire program) if you are defining things in a header for utility functions that you don't want to have to define again in each c file. I.E. defining an enum and a static function to translate the enum to a string. Then you won't have to rewrite the enum to string translator for each .c file that includes the header. :)

Some of the "getResourceAsStream()" options in this answer didn't work for me, but this one did:
SomeClassWithinYourSourceDir.class.getClassLoader().getResourceAsStream("yourResource");
Instead of bar
use self.bar
or Foo.bar
. Assigning to Foo.bar
will create a static variable, and assigning to self.bar
will create an instance variable.
Here is an example in C:
char hello[] = "hello";
char *p = hello;
while (*p)
{
*p += 1; // increase the character by one
p += 1; // move to the next spot
}
printf(hello);
prints
ifmmp
because it takes the value for each character and increments it by one.
If you just need the name of the current directory, you could do something like this:

I'm writing this answer w.r.t. to python 3, as I've initially got the same problem.
I was supposed to get data from arduino using PySerial
, and write them in a .csv file. Each reading in my case ended with '\r\n'
, so newline was always separating each line.
In my case, newline=''
option didn't work. Because it showed some error like :
with open('op.csv', 'a',newline=' ') as csv_file:
ValueError: illegal newline value: ''
So it seemed that they don't accept omission of newline here.
Seeing one of the answers here only, I mentioned line terminator in the writer object, like,
writer = csv.writer(csv_file, delimiter=' ',lineterminator='\r')
and that worked for me for skipping the extra newlines.
How about
when( method-call ).thenReturn( value1, value2, value3 );
You can put as many arguments as you like in the brackets of thenReturn, provided they're all the correct type. The first value will be returned the first time the method is called, then the second answer, and so on. The last value will be returned repeatedly once all the other values are used up.
The code generates a compilation error because your instance type is an Animal:
Animal animal=new Animal();
Downcasting is not allowed in Java for several reasons. See here for details.
Followed Mark's advise and did this to set the default number formatting to text in the whole workbook:
$objPHPExcel = new PHPExcel();

And it works flawlessly. Thank you, Mark Baker.

Login to virtual machine use below command to check ip address. (anyone will work)
If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1
If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine
If you want to show those number values as a time then change the format of the cell to Time.

See this link, following is quoted from there:
A BufferedReader is a simple class meant to efficiently read from the underling stream. Generally, each read request made of a Reader like a FileReader causes a corresponding read request to be made to underlying stream. Each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient. Efficiency is improved appreciably if a Reader is warped in a BufferedReader.
BufferedReader is synchronized, so read operations on a BufferedReader can safely be done from multiple threads.
A scanner on the other hand has a lot more cheese built into it; it can do all that a BufferedReader can do and at the same level of efficiency as well. However, in addition a Scanner can parse the underlying stream for primitive types and strings using regular expressions. It can also tokenize the underlying stream with the delimiter of your choice. It can also do forward scanning of the underlying stream disregarding the delimiter!
A scanner however is not thread safe, it has to be externally synchronized.
The choice of using a BufferedReader or a Scanner depends on the code you are writing, if you are writing a simple log reader Buffered reader is adequate. However if you are writing an XML parser Scanner is the more natural choice.
Even while reading the input, if want to accept user input line by line and say just add it to a file, a BufferedReader is good enough. On the other hand if you want to accept user input as a command with multiple options, and then intend to perform different operations based on the command and options specified, a Scanner will suit better.
Just wondering why you are using 2 directives?
It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.
Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).
It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.
Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.
I am not sure will this be useful for anyone, since I had to provide other users of the system to schedule the jobs, without giving them access to the actual server(windows) Task Scheduler, I created this reusable app.
Please note users have access to one shared folder on server where they can create required command/task/.bat file. This task then can be scheduled using this app.
App name is Django_Windows_Scheduler
If you have simple floats that you control the range of, you can also have an integer in the resources and divide by the number of decimal places you need straight in code.
So something like this
<integer name="strokeWidth">356</integer>
is used with 2 decimal places
this.strokeWidthFromResources = resources_.getInteger(R.integer.strokeWidth);
circleOptions.strokeWidth((float) strokeWidthFromResources/ 100);
and that makes it 3.56f
Not saying this is the most elegant solution but for simple projects, it's convenient.
This answer is not just for C++ since everything mentioned is about the data structures themselves, regardless of language. And, my answer is assuming that you know the basic structure of adjacency lists and matrices.
If memory is your primary concern you can follow this formula for a simple graph that allows loops:
An adjacency matrix occupies n2/8 byte space (one bit per entry).
An adjacency list occupies 8e space, where e is the number of edges (32bit computer).
If we define the density of the graph as d = e/n2 (number of edges divided by the maximum number of edges), we can find the "breakpoint" where a list takes up more memory than a matrix:
8e > n2/8 when d > 1/64
So with these numbers (still 32-bit specific) the breakpoint lands at 1/64. If the density (e/n2) is bigger than 1/64, then a matrix is preferable if you want to save memory.
You can read about this at wikipedia (article on adjacency matrices) and a lot of other sites.
Side note: One can improve the space-efficiency of the adjacency matrix by using a hash table where the keys are pairs of vertices (undirected only).
Adjacency lists are a compact way of representing only existing edges. However, this comes at the cost of possibly slow lookup of specific edges. Since each list is as long as the degree of a vertex the worst case lookup time of checking for a specific edge can become O(n), if the list is unordered. However, looking up the neighbours of a vertex becomes trivial, and for a sparse or small graph the cost of iterating through the adjacency lists might be negligible.
Adjacency matrices on the other hand use more space in order to provide constant lookup time. Since every possible entry exists you can check for the existence of an edge in constant time using indexes. However, neighbour lookup takes O(n) since you need to check all possible neighbours. The obvious space drawback is that for sparse graphs a lot of padding is added. See the memory discussion above for more information on this.
If you're still unsure what to use: Most real-world problems produce sparse and/or large graphs, which are better suited for adjacency list representations. They might seem harder to implement but I assure you they aren't, and when you write a BFS or DFS and want to fetch all neighbours of a node they're just one line of code away. However, note that I'm not promoting adjacency lists in general.
I had a similar issue. In my case, I had to uninstall and then reinstall pip3:
sudo apt-get remove python3-pip
sudo apt-get install python3-pip
You are trying to get width and height of an elements, that weren't drawn yet.
If you use debug and stop at some point, you'll see, that your device screen is still empty, that's because your elements weren't drawn yet, so you can't get width and height of something, that doesn't yet exist.
And, I might be wrong, but setWidth()
is not always respected, Layout
lays out it's children and decides how to measure them (calling child.measure()
), so If you set setWidth()
, you are not guaranteed to get this width after element will be drawn.
What you need, is to use getMeasuredWidth()
(the most recent measure of your View) somewhere after the view was actually drawn.
Look into Activity
lifecycle for finding the best moment.
http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
I believe a good practice is to use OnGlobalLayoutListener
like this:
yourView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
if (!mMeasured) {
// Here your view is already layed out and measured for the first time
mMeasured = true; // Some optional flag to mark, that we already got the sizes
}
}
});
You can place this code directly in onCreate()
, and it will be invoked when views will be laid out.
If you pass the -v
flag to the ansible-playbook command, then ansible will show the output on your terminal.
For your use case, you may want to try using the fetch module to copy the public key from the server to your local machine. That way, it will only show a "changed" status when the file changes.
If you only need the dictionary keys 1
, 2
, and 3
use: your_dict.keys()
.
If you only need the dictionary values -0.3246
, -0.9185
, and -3985
use: your_dict.values()
.
If you want both keys and values use: your_dict.items()
which returns a list of tuples [(key1, value1), (key2, value2), ...]
.
It's simple: give the parent div this:
display: table;
and give the child div(s) this:
display: table-cell;
vertical-align: middle;
That's it!

display: table;_x000D_
}_x000D_
.child{_x000D_
display: table-cell;_x000D_

Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.
After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.
I would prefer using "&&" -operator on inline if-statement. In my opinnion it gives cleaner codebase this way.
Generally you could be doing something like this
render(){
return(
<div>
<button className={this.state.active && 'active'}
onClick={ () => this.setState({active: !this.state.active}) }>Click me</button>
</div>
)
}
Just keep in mind arrow function is ES6 feature and remember to set 'this.state.active' value in class constructor(){}
this.state = { active: false }
or if you want to inject css in JSX you are able to do it this way
<button style={this.state.active && style.button} >button</button>
and you can declare style json variable
const style = { button: { background:'red' } }
remember using camelCase on JSX stylesheets.
The Mono project dropped Windows XP support and "forgot" to mention it. Although they still claim Windows XP SP2 is the minimum supported version, it is actually Windows Vista.
The last version of Mono to support Windows XP was 3.2.3.
My solution to your problem would be to either:
1 - use int instead of enums: Declare your ints in an anonymous namespace in your CPP file (not in the header):
namespace
{
const int FUNCTIONALITY_NORMAL = 0 ;
const int FUNCTIONALITY_RESTRICTED = 1 ;
const int FUNCTIONALITY_FOR_PROJECT_X = 2 ;
}
As your methods are private, no one will mess with the data. You could even go further to test if someone sends you an invalid data:
namespace
{
const int FUNCTIONALITY_begin = 0 ;
const int FUNCTIONALITY_NORMAL = 0 ;
const int FUNCTIONALITY_RESTRICTED = 1 ;
const int FUNCTIONALITY_FOR_PROJECT_X = 2 ;
const int FUNCTIONALITY_end = 3 ;
bool isFunctionalityCorrect(int i)
{
return (i >= FUNCTIONALITY_begin) && (i < FUNCTIONALITY_end) ;
}
}
2 : create a full class with limited const instantiations, like done in Java. Forward declare the class, and then define it in the CPP file, and instanciate only the enum-like values. I did something like that in C++, and the result was not as satisfying as desired, as it needed some code to simulate an enum (copy construction, operator =, etc.).
3 : As proposed before, use the privately declared enum. Despite the fact an user will see its full definition, it won't be able to use it, nor use the private methods. So you'll usually be able to modify the enum and the content of the existing methods without needing recompiling of code using your class.
My guess would be either the solution 3 or 1.
The website you linked doesn't changes the image's width but it actually cuts it off. For that it needs to be set as a background-image.
For more info about background-image
look it at http://www.w3schools.com/cssref/pr_background-image.asp
Usage:
#divID {
background-image:url(image_url);
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
I have studied a number of Go projects and there is a fair bit of variation. You can kind of tell who is coming from C and who is coming from Java, as the former dump just about everything in the projects root directory in a main
package, and the latter tend to put everything in a src
directory. Neither is optimal however. Each have consequences because they affect import paths and how others can reuse them.
To get the best results I have worked out the following approach.
myproj/
main/
mypack.go
mypack.go
Where mypack.go
is package mypack
and main/mypack.go
is (obviously) package main
.
If you need additional support files you have two choices. Either keep them all in the root directory, or put private support files in a lib
subdirectory. E.g.
myproj/
main/
mypack.go
myextras/
someextra.go
mypack.go
mysupport.go
Or
myproj.org/
lib/
mysupport.go
myextras/
someextra.go
main/
mypack.go
mypage.go
Only put the files in a lib
directory if they are not intended to be imported by another project. In other words, if they are private support files. That's the idea behind having lib
--to separate public from private interfaces.
Doing things this way will give you a nice import path, myproj.org/mypack
to reuse the code in other projects. If you use lib
then internal support files will have an import path that is indicative of that, myproj.org/lib/mysupport
.
When building the project, use main/mypack
, e.g. go build main/mypack
. If you have more than one executable you can also separate those under main
without having to create separate projects. e.g. main/myfoo/myfoo.go
and main/mybar/mybar.go
.

If you have separated files for angular app\resources\directives and other stuff then you can just disable minification of your angular app bundle like this (use new Bundle() instead of ScriptBundle() in your bundle config file):
bundles.Add(
new Bundle("~/bundles/angular/SomeBundleName").Include(
"~/Content/js/angular/Pages/Web/MainPage/angularApi.js",
"~/Content/js/angular/Pages/Web/MainPage/angularApp.js",
"~/Content/js/angular/Pages/Web/MainPage/angularCtrl.js"));
And angular app would appear in bundle unmodified.
unicode_escape
doesn't work in generalIt turns out that the string_escape
or unicode_escape
solution does not work in general -- particularly, it doesn't work in the presence of actual Unicode.
If you can be sure that every non-ASCII character will be escaped (and remember, anything beyond the first 128 characters is non-ASCII), unicode_escape
will do the right thing for you. But if there are any literal non-ASCII characters already in your string, things will go wrong.
unicode_escape
is fundamentally designed to convert bytes into Unicode text. But in many places -- for example, Python source code -- the source data is already Unicode text.
The only way this can work correctly is if you encode the text into bytes first. UTF-8 is the sensible encoding for all text, so that should work, right?
The following examples are in Python 3, so that the string literals are cleaner, but the same problem exists with slightly different manifestations on both Python 2 and 3.
>>> s = 'naïve \\t test'
>>> print(s.encode('utf-8').decode('unicode_escape'))
naïve test
Well, that's wrong.
The new recommended way to use codecs that decode text into text is to call codecs.decode
directly. Does that help?
>>> import codecs
>>> print(codecs.decode(s, 'unicode_escape'))
naïve test
Not at all. (Also, the above is a UnicodeError on Python 2.)
The unicode_escape
codec, despite its name, turns out to assume that all non-ASCII bytes are in the Latin-1 (ISO-8859-1) encoding. So you would have to do it like this:
>>> print(s.encode('latin-1').decode('unicode_escape'))
naïve test
But that's terrible. This limits you to the 256 Latin-1 characters, as if Unicode had never been invented at all!
>>> print('Erno \\t Rubik'.encode('latin-1').decode('unicode_escape'))
UnicodeEncodeError: 'latin-1' codec can't encode character '\u0151'
in position 3: ordinal not in range(256)
(Surprisingly, we do not now have two problems.)
What we need to do is only apply the unicode_escape
decoder to things that we are certain to be ASCII text. In particular, we can make sure only to apply it to valid Python escape sequences, which are guaranteed to be ASCII text.
The plan is, we'll find escape sequences using a regular expression, and use a function as the argument to re.sub
to replace them with their unescaped value.
import re
import codecs
ESCAPE_SEQUENCE_RE = re.compile(r'''
( \\U........ # 8-digit hex escapes
| \\u.... # 4-digit hex escapes
| \\x.. # 2-digit hex escapes
| \\[0-7]{1,3} # Octal escapes
| \\N\{[^}]+\} # Unicode characters by name
| \\[\\'"abfnrtv] # Single-character escapes
)''', re.UNICODE | re.VERBOSE)
def decode_escapes(s):
def decode_match(match):
return codecs.decode(match.group(0), 'unicode-escape')
return ESCAPE_SEQUENCE_RE.sub(decode_match, s)
And with that:
>>> print(decode_escapes('Erno \\t Rubik'))
Erno Rubik
Assuming you've checked the file is actually present on the server, this could also be caused by your web server restricting which file types are served:
While Loop example in T-SQL which list current month's beginning to end date.
DECLARE @Today DATE= GETDATE() ,
@StartOfMonth DATE ,
@EndOfMonth DATE;
DECLARE @DateList TABLE ( DateLabel VARCHAR(10) );
SET @EndOfMonth = EOMONTH(GETDATE());
SET @StartOfMonth = DATEFROMPARTS(YEAR(@Today), MONTH(@Today), 1);
WHILE @StartOfMonth <= @EndOfMonth
BEGIN
INSERT INTO @DateList
VALUES ( @StartOfMonth );
SET @StartOfMonth = DATEADD(DAY, 1, @StartOfMonth);
END;
SELECT DateLabel
FROM @DateList;
sys.argv[0]
is not the first argument but the filename of the python program you are currently executing. I think you want sys.argv[1]

Simple answer: give these two tds a style field.
<tr>
<td>One</td>
<td style="padding-right: 10px">Two</td>
<td>Three</td>
<td>Four</td>
</tr>
Tidy one: use class name
<tr>
<td>One</td>
<td class="more-padding-on-right">Two</td>
<td>Three</td>
<td>Four</td>
</tr>
.more-padding-on-right {
padding-right: 10px;
}
Complex one: using nth-child selector in CSS and specify special padding values for these two, which works in modern browsers.
tr td:nth-child(2) {
padding-right: 10px;
}?

This code above is the side effect of the solving Javascript's asynchronous callback hell problem. This is also the reason I think that makes Javascript a useful language in the backend. Actually this is the most exciting improvement introduced to modern Javascript in my opinion. To fully understand how it works, how generator works needs to be fully understood. The function
keyword followed by a *
is called a generator function in modern Javascript. The npm package co
provided a runner function to run a generator.
Essentially generator function provided a way to pause the execution of a function with yield
keyword, at the same time, yield
in a generator function made it possible to exchange information between inside the generator and the caller. This provided a mechanism for the caller to extract data from a promise
from an asynchronous call and to pass the resolved data back to the generator. Effectively, it makes an asynchronous call synchronous.
You can do it like this,
<input type="text" name="name" value="<?php echo $name;?>" />
But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.
<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />
<form>
<label for="company">
<span>Company Name</span>
<input type="text" id="company" />
</label>
<label for="contact">
<span>Contact Name</span>
<input type="text" id="contact" />
</label>
</form>
label { width: 200px; float: left; margin: 0 20px 0 0; }
span { display: block; margin: 0 0 3px; font-size: 1.2em; font-weight: bold; }
input { width: 200px; border: 1px solid #000; padding: 5px; }

Javascript always passes by value. However, if you pass an object to a function, the "value" is really a reference to that object, so the function can modify that object's properties but not cause the variable outside the function to point to some other object.
An example:
function changeParam(x, y, z) {
x = 3;
y = "new string";
z["key2"] = "new";
z["key3"] = "newer";
z = {"new" : "object"};
}
var a = 1,
b = "something",
c = {"key1" : "whatever", "key2" : "original value"};
changeParam(a, b, c);
// at this point a is still 1
// b is still "something"
// c still points to the same object but its properties have been updated
// so it is now {"key1" : "whatever", "key2" : "new", "key3" : "newer"}
// c definitely doesn't point to the new object created as the last line
// of the function with z = ...
row=list(map(int,input().split())) #input no. of row and column
b=[]
for i in range(0,row[0]):
print('value of i: ',i)
a=list(map(int,input().split()))
print(a)
b.append(a)
print(b)
print(row)
Output:
2 3
value of i:0
1 2 4 5
[1, 2, 4, 5]
value of i: 1
2 4 5 6
[2, 4, 5, 6]
[[1, 2, 4, 5], [2, 4, 5, 6]]
[2, 3]
Note: this code in case of control.it only control no. Of rows but we can enter any number of column we want i.e row[0]=2
so be careful. This is not the code where you can control no of columns.

Option 1 : Without hiding the console window, passing arguments and without getting the outputs
using System;
using System.Diagnostics;
namespace ConsoleApplication
{
class Program
{
static void Main(string[] args)
{
System.Diagnostics.Process.Start(@"c:\batchfilename.bat", "\"1st\" \"2nd\"");
}
}
}
Option 2 : Hiding the console window, passing arguments and taking outputs
using System;
using System.Diagnostics;
namespace ConsoleApplication
{
class Program
{
static void Main(string[] args)
{
var process = new Process();
var startinfo = new ProcessStartInfo(@"c:\batchfilename.bat", "\"1st_arg\" \"2nd_arg\" \"3rd_arg\"");
startinfo.RedirectStandardOutput = true;
startinfo.UseShellExecute = false;
process.StartInfo = startinfo;
process.OutputDataReceived += (sender, argsx) => Console.WriteLine(argsx.Data); // do whatever processing you need to do in this handler
process.Start();
process.BeginOutputReadLine();
process.WaitForExit();
}

This solution works if you have access to the mail server or you can request something to the mail server
Administrator:
1) Create a group in the mail server
: Sales Department
2) Assign to the group
the accounts you need to be in the group
3) Assign an internet address to the group: [email protected]
4) Create your PHP script using the mail function:
$to = "[email protected]";
mail($to, $subject, $message, $headers);
It worked for me and all the accounts included in the group receive the mail.
The best of the lucks.
It's pretty domain-specific, but half-edge data structure is pretty neat. It provides a way to iterate over polygon meshes (faces and edges) which is very useful in computer graphics and computational geometry.

Odd to say I remember it because it is the opposite of the typewriter I used.
Well if it was normal I had no need to remember it... :-)
In the typewriter when you finish to digit the line you use the carriage return lever, that before makes roll the drum, the newline, and after allow you to manually operate the carriage return.
You can listen from this record from freesound.org the sound of the paper feeding in the beginning, and at around -1:03 seconds from the end, after the bell warning for the end of the line sound of the drum that rolls and after the one of the carriage return.

where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.
This basically means that the following XML element
<foo>hello
wor
ld</foo>
could be represented like this in a denormalized node:
Element foo
Text node: ""
Text node: "Hello "
Text node: "wor"
Text node: "ld"
When normalized, the node will look like this
Element foo
Text node: "Hello world"
And the same goes for attributes: <foo bar="Hello world"/>
, comments, etc.
Your layout in xml probably already has a layout_margin(Left|Right|etc) attribute in it, which means you need to access the object generated by that xml and modify it.
I found this solution to be very simple:
ViewGroup.MarginLayoutParams mlp = (ViewGroup.MarginLayoutParams) mTextView
.getLayoutParams();
mlp.setMargins(adjustmentPxs, 0, 0, 0);
break;
Get the LayoutParams instance of your textview, downcast it to MarginLayoutParams, and use the setMargins method to set the margins.
setBounds
is used to define the bounding rectangle of a component. This includes it's position and size.
The is used in a number of places within the framework.
For the most part, you should never call it. Instead, you should use appropriate layout managers and let them determine the best way to provide information to this method.
Slightly different approach:
MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("HeaderName", "value");
headers.add("Content-Type", "application/json");
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
HttpEntity<ObjectToPass> request = new HttpEntity<ObjectToPass>(objectToPass, headers);
restTemplate.postForObject(url, request, ClassWhateverYourControllerReturns.class);
import java.text.DecimalFormat;
public class RoundTest {
public static void main(String[] args) {
double i = 2;
DecimalFormat twoDForm = new DecimalFormat("#.00");
System.out.println(twoDForm.format(i));
double j=3.1;
System.out.println(twoDForm.format(j));
double k=4.144456;
System.out.println(twoDForm.format(k));
}
}
Simply use FIND_IN_SET like that:
mysql> SELECT FIND_IN_SET('b','a,b,c,d');
-> 2
so you can do:
select * from Fruits where FIND_IN_SET(fruit, fruitArray) > 0
You can change the tint, quite easily in code via:
imageView.setColorFilter(Color.argb(255, 255, 255, 255));
// White Tint
If you want color tint then
imageView.setColorFilter(ContextCompat.getColor(context, R.color.COLOR_YOUR_COLOR), android.graphics.PorterDuff.Mode.MULTIPLY);
For Vector Drawable
imageView.setColorFilter(ContextCompat.getColor(context, R.color.COLOR_YOUR_COLOR), android.graphics.PorterDuff.Mode.SRC_IN);
UPDATE:
@ADev has newer solution in his answer here, but his solution requires newer support library - 25.4.0 or above.
You need to try one of the following:
They offer many more features and will be easier to get what you are looking for.
The simplest way to extract a number from a string is to use regular expressions and findall
.
>>> import re
>>> s = '300 gm'
>>> re.findall('\d+', s)
['300']
>>> s = '300 gm 200 kgm some more stuff a number: 439843'
>>> re.findall('\d+', s)
['300', '200', '439843']
It might be that you need something more complex, but this is a good first step.
Note that you'll still have to call int
on the result to get a proper numeric type (rather than another string):
>>> map(int, re.findall('\d+', s))
[300, 200, 439843]
In Ipython
shell:
In [8]: import subprocess
In [9]: s=subprocess.check_output(["echo", "Hello World!"])
In [10]: s
Out[10]: 'Hello World!\n'

For the sake of over-explicit brainlessness, after following marc_s' instructions to here...
In SSMS in the Object Explorer, right click on the database right-click and pick "Tasks" and then "Generate Scripts".
... I then see a wizard screen with "Introduction, Choose Objects, Set Scripting Options, Summary, and Save or Publish Scripts" with prev, next, finish, cancel buttons at the bottom.
On the Set Scripting Options step, you have to click "Advanced" to get the page with the options. Then, as Ghlouw has mentioned, you now select "Types of data to script" and profit.
It is the $sce
service that blocks URLs with external domains, it is a service that provides Strict Contextual Escaping services to AngularJS, to prevent security vulnerabilities such as XSS, clickjacking, etc. it's enabled by default in Angular 1.2.
You can disable it completely, but it's not recommended
angular.module('myAppWithSceDisabledmyApp', [])
.config(function($sceProvider) {
$sceProvider.enabled(false);
});

First argument in update
method is SyntheticEvent
object that contains common properties and methods to any event
, it is not reference to React component where there is property props
.
if you need pass argument to update method you can do it like this
onClick={ (e) => this.props.onClick(e, 'home', 'Home') }
and get these arguments inside update
method
update(e, space, txt){
console.log(e.target, space, txt);
}
event.target
gives you the native DOMNode
, then you need to use the regular DOM APIs to access attributes. For instance getAttribute
or dataset
<button
data-space="home"
className="home"
data-txt="Home"
onClick={ this.props.onClick }
/>
Button
</button>
onClick(e) {
console.log(e.target.dataset.txt, e.target.dataset.space);
}
I know it's maybe a little late to answer this question but, more data is not going to kill someone. Here's a very fast function :
function format_filesize($B, $D=2){
$S = 'BkMGTPEZY';
$F = floor((strlen($B) - 1) / 3);
return sprintf("%.{$D}f", $B/pow(1024, $F)).' '.@$S[$F].'B';
}
EDIT: I updated my post to include the fix proposed by camomileCase:
function format_filesize($B, $D=2){
$S = 'kMGTPEZY';
$F = floor((strlen($B) - 1) / 3);
return sprintf("%.{$D}f", $B/pow(1024, $F)).' '.@$S[$F-1].'B';
}
You must declare the prototype it before using it:
class User;
class MyMessageBox
{
public:
void sendMessage(Message *msg, User *recvr);
Message receiveMessage();
vector<Message> *dataMessageList;
};
class User
{
public:
MyMessageBox dataMsgBox;
};
edit: Swapped the types
Do you see what the DatabaseUtils.queryNumEntries() does? It's awful! I use this.
public int getRowNumberByArgs(Object... args) {
String where = compileWhere(args);
String raw = String.format("SELECT count(*) FROM %s WHERE %s;", TABLE_NAME, where);
Cursor c = getWriteableDatabase().rawQuery(raw, null);
try {
return (c.moveToFirst()) ? c.getInt(0) : 0;
} finally {
c.close();
}
}

Just elaborating what Paul added in comment. The page mentioned above is dead after 2010, so read with a pinch of salt. Lot of stuff has been been changed in 3 years.
Both these will give you the first child node:
console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);
If you need the first child that is an element node then use:
console.log(parentElement.children[0]);
Edit
Ah, I see your problem now; parentElement
is an array.
If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0]
to dearray (yes, I made that word up) the element:
var parentElement = document.getElementsByClassName("uniqueClassName")[0];
You can use binding expressions:
private void ComboBox_Loaded(object sender, RoutedEventArgs e)
{
((ComboBox)sender).GetBindingExpression(ComboBox.ItemsSourceProperty)
.UpdateTarget();
}
But as Blindmeis noted you can also fire change notifications, further if your collection implements INotifyCollectionChanged
(for example implemented in the ObservableCollection<T>
) it will synchronize so you do not need to do any of this.
I want to add a point that you can also (and should if what you are writing is complex) add a test variable to rollback if you are in test mode. Then you can execute the whole thing at once. Often I also add code to see the before and after results of various operations especially if it is a complex script.
Example below:
USE AdventureWorks;
GO
DECLARE @TEST INT = 1--1 is test mode, use zero when you are ready to execute
BEGIN TRANSACTION;
BEGIN TRY
IF @TEST= 1
BEGIN
SELECT *FROM Production.Product
WHERE ProductID = 980;
END
-- Generate a constraint violation error.
DELETE FROM Production.Product
WHERE ProductID = 980;
IF @TEST= 1
BEGIN
SELECT *FROM Production.Product
WHERE ProductID = 980;
IF @@TRANCOUNT > 0
ROLLBACK TRANSACTION;
END
END TRY
BEGIN CATCH
SELECT
ERROR_NUMBER() AS ErrorNumber
,ERROR_SEVERITY() AS ErrorSeverity
,ERROR_STATE() AS ErrorState
,ERROR_PROCEDURE() AS ErrorProcedure
,ERROR_LINE() AS ErrorLine
,ERROR_MESSAGE() AS ErrorMessage;
IF @@TRANCOUNT > 0
ROLLBACK TRANSACTION;
END CATCH;
IF @@TRANCOUNT > 0 AND @TEST = 0
COMMIT TRANSACTION;
GO
Assuming you are dealing with a JSON-string in the input, you can parse it using the json
package, see the documentation.
In the specific example you posted you would need
x = json.loads("""{
"accountWide": true,
"criteria": [
{
"description": "some description",
"id": 7553,
"max": 1,
"orderIndex": 0
}
]
}""")
description = x['criteria'][0]['description']
id = x['criteria'][0]['id']
max = x['criteria'][0]['max']
You can also turn on WCF logging for more information about the original error. This helped me solve this problem.
Add the following to your web.config, it saves the log to C:\log\Traces.svclog

If you have tsocks or proxychains installed and configured, you can
$ tsocks git clone <you_repository>
or
$ proxychains git clone <you_repository>
to make it shorter, I created a symbol link /usr/bin/p
for proxychains
, so I can use it like this
p git clone <you_repository>
and I can use it to proxy any command,
p <cmd-need-be-proxied>
by the way, proxychains is not updated for a long time, you may wanna try proxychians-ng
Be aware that the in
operator tests not only equality (==
) but also identity (is
), the in
logic for list
s is roughly equivalent to the following (it's actually written in C and not Python though, at least in CPython):
for element in s: if element is target: # fast check for identity implies equality return True if element == target: # slower check for actual equality return True return False
In most circumstances this detail is irrelevant, but in some circumstances it might leave a Python novice surprised, for example, numpy.NAN
has the unusual property of being not being equal to itself:
>>> import numpy
>>> numpy.NAN == numpy.NAN
False
>>> numpy.NAN is numpy.NAN
True
>>> numpy.NAN in [numpy.NAN]
True
To distinguish between these unusual cases you could use any()
like:
>>> lst = [numpy.NAN, 1 , 2]
>>> any(element == numpy.NAN for element in lst)
False
>>> any(element is numpy.NAN for element in lst)
True
Note the in
logic for list
s with any()
would be:
any(element is target or element == target for element in lst)
However, I should emphasize that this is an edge case, and for the vast majority of cases the in
operator is highly optimised and exactly what you want of course (either with a list
or with a set
).
There is no option to downgrade XAMPP. XAMPP is hardcoded with specific PHP version to make sure all the modules are compatible and working properly. However if your project needs PHP 5.6, you can just install a older version of XAMPP with PHP 5.6 packaged into it.
You can always use the 'pre' tag inside the label, and just enter the blank spaces in it, So you can always add the same or different number of spaces you require
<form>
<label>First Name :<pre>Here just enter number of spaces you want to use(I mean using spacebar to enter blank spaces)</pre>
<input type="text"></label>
<label>Last Name :<pre>Now Enter enter number of spaces to match above number of
spaces</pre>
<input type="text"></label>
</form>

Simply use list property count\
i = ['apple','red','apple','red','red','pear']
d = {x:i.count(x) for x in i}
print d
output :
{'pear': 1, 'apple': 2, 'red': 3}
The next()
moves the cursor froward one row from its current position in the resultset
. so its evident that if(rs.next())
means that if the next row is not null
(means if it exist), Go Ahead.
Now w.r.t your problem,
ResultSet rs = stmt.executeQuery(sql); //This is wrong
^
note that executeQuery(String) is used in case you use a sql-query as string.
Whereas when you use a PreparedStatement, use executeQuery() which executes the SQL query in this PreparedStatement
object and returns the ResultSet
object generated by the query.
Solution :
Use : ResultSet rs = stmt.executeQuery();
There might be another way, but this should work:

and year(Submission_date)=year(now)
Have read the documentation you've linked. That's totally silly! xclip
is just a clipboard. You'll find other ways to copy paste the key... (I'm sure)
If you aren't working from inside a graphical X session you need to pass the $DISPLAY
environment var to the command. Run it like this:
DISPLAY=:0 xclip -sel clip < ~/.ssh/id_rsa.pub
Of course :0
depends on the display you are using. If you have a typical desktop machine it is likely that it is :0
If you want to merge the filters (eg. CSV and Excel files), use this formula:
OpenFileDialog of = new OpenFileDialog();
of.Filter = "CSV files (*.csv)|*.csv|Excel Files|*.xls;*.xlsx";
Or if you want to see XML or PDF files in one time use this:
of.Filter = @" XML or PDF |*.xml;*.pdf";
I've used this method successfully:
System.Reflection.Assembly.GetExecutingAssembly().CreateInstance(string className)
You'll need to cast the returned object to your desired object type.
How about this?
WAITFOR DELAY '00:00:02';
If you have "00:02" it's interpreting that as Hours:Minutes.
preg_replace('#[^\w()/.%\-&]#',"",$string);
I was downloading video files. Apache's FTPClient fumbled, it downloaded the video reasonably fast. but when I tried to play the video back, it lost chunks out of the middle of the video. ftp4j would download the whole video with no loss.

Three years late, but my Googling brought me here so hopefully my answer will be useful for someone else.
I just created a second option (which I hid with CSS) and used Javascript to move the s backwards and forwards between them.
<select multiple id="sel1">
<option class="set1">Blah</option>
</select>
<select multiple id="sel2" style="display:none">
<option class="set2">Bleh</option>
</select>
Something like that, and then something like this will move an item onto the list (i.e., make it visible). Obviously adapt the code as needed for your purpose.
$('#sel2 .set2').appendTo($('#sel1'))
URL url = new URL(yourUrl, "/api/v1/status.xml");
According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:
URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Use this to list Grantee too and remove (PG_monitor and Public) for Postgres PaaS Azure.
SELECT grantee,table_catalog, table_schema, table_name, privilege_type
FROM information_schema.table_privileges
WHERE grantee not in ('pg_monitor','PUBLIC');
You can query the all_tab_columns
view in the database.
SELECT table_name, column_name, data_type, data_length FROM all_tab_columns where table_name = 'CUSTOMER'
You could use something like this to give your button a value:
<?php
if (isset($_POST['submit'])) {
$aSubmitVal = array_keys($_POST['submit'])[0];
echo 'The button value is: ' . $aSubmitVal;
}
?>
<form action="/" method="post">
<input id="someId" type="submit" name="submit[SomeValue]" value="Button name">
</form>
This will give you the string "SomeValue" as a result
The simplest approach is to use a multitouch JavaScript library like Hammer.js. Then you can write code like:
canvas
.hammer({prevent_default: true})
.bind('doubletap', function(e) { // And double click
// Zoom-in
})
.bind('dragstart', function(e) { // And mousedown
// Get ready to drag
})
.bind('drag', function(e) { // And mousemove when mousedown
// Pan the image
})
.bind('dragend', function(e) { // And mouseup
// Finish the drag
});
And you can keep going. It supports tap, double tap, swipe, hold, transform (i.e., pinch) and drag. The touch events also fire when equivalent mouse actions happen, so you don't need to write two sets of event handlers. Oh, and you need the jQuery plugin if you want to be able to write in the jQueryish way as I did.
Instead of adding the line breaks with nl2br() and then removing the line breaks with explode(), try using the line break character '\r' or '\n' or '\r\n'.
<?php $options= file_get_contents("employees.txt"); $options=explode("\n",$options); // try \r as well. foreach ($options as $singleOption){ echo "<option value='".$singleOption."'>".$singleOption."</option>"; } ?>
This could also fix the issue if the problem was due to Google Spreadsheets reading the line breaks.
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 1);
cal.set(Calendar.MONTH, 1);
cal.set(Calendar.YEAR, 2012);
cal.add(Calendar.DAY_OF_MONTH, 5);
You can also substract days like Calendar.add(Calendar.DAY_OF_MONTH, -5);
In general, methods that end in !
indicate that the method will modify the object it's called on. Ruby calls these as "dangerous methods" because they change state that someone else might have a reference to. Here's a simple example for strings:
foo = "A STRING" # a string called foo
foo.downcase! # modifies foo itself
puts foo # prints modified foo
This will output:
a string
In the standard libraries, there are a lot of places you'll see pairs of similarly named methods, one with the !
and one without. The ones without are called "safe methods", and they return a copy of the original with changes applied to the copy, with the callee unchanged. Here's the same example without the !
:
foo = "A STRING" # a string called foo
bar = foo.downcase # doesn't modify foo; returns a modified string
puts foo # prints unchanged foo
puts bar # prints newly created bar
This outputs:
A STRING
a string
Keep in mind this is just a convention, but a lot of Ruby classes follow it. It also helps you keep track of what's getting modified in your code.
you can install the script ;
pip3 install --user advance-touch
After installed, you can use ad command

There are many questions about REST auth patterns here on SO. These are the most relevant for your question:
Basically you need to choose between using API keys (least secure as the key may be discovered by an unauthorized user), an app key and token combo (medium), or a full OAuth implementation (most secure).
This isn't an answer. I just want to show that IF NOT EXISTS(...) INSERT
method isn't safe. You have to execute first Session #1
and then Session #2
. After v #2
you will see that without an UNIQUE
index you could get duplicate pairs (SoftwareName,SoftwareSystemType)
. Delay from session #1 is used to give you enough time to execute the second script (session #2). You could reduce this delay.

null
is not an object, it is a primitive value. For example, you cannot add properties to it. Sometimes people wrongly assume that it is an object, because typeof null
returns "object"
. But that is actually a bug (that might even be fixed in ECMAScript 6).
The difference between null
and undefined
is as follows:
undefined
: used by JavaScript and means “no value”. Uninitialized variables, missing parameters and unknown variables have that value.
> var noValueYet;
> console.log(noValueYet);
undefined
> function foo(x) { console.log(x) }
> foo()
undefined
> var obj = {};
> console.log(obj.unknownProperty)
undefined
Accessing unknown variables, however, produces an exception:
> unknownVariable
ReferenceError: unknownVariable is not defined
null
: used by programmers to indicate “no value”, e.g. as a parameter to a function.
Examining a variable:
console.log(typeof unknownVariable === "undefined"); // true
var foo;
console.log(typeof foo === "undefined"); // true
console.log(foo === undefined); // true
var bar = null;
console.log(bar === null); // true
As a general rule, you should always use === and never == in JavaScript (== performs all kinds of conversions that can produce unexpected results). The check x == null
is an edge case, because it works for both null
and undefined
:
> null == null
true
> undefined == null
true
A common way of checking whether a variable has a value is to convert it to boolean and see whether it is true
. That conversion is performed by the if
statement and the boolean operator ! (“not”).
function foo(param) {
if (param) {
// ...
}
}
function foo(param) {
if (! param) param = "abc";
}
function foo(param) {
// || returns first operand that can't be converted to false
param = param || "abc";
}
Drawback of this approach: All of the following values evaluate to false
, so you have to be careful (e.g., the above checks can’t distinguish between undefined
and 0
).
undefined
, null
false
+0
, -0
, NaN
""
You can test the conversion to boolean by using Boolean
as a function (normally it is a constructor, to be used with new
):
> Boolean(null)
false
> Boolean("")
false
> Boolean(3-3)
false
> Boolean({})
true
> Boolean([])
true

For example: https://jsfiddle.net/lesac4/jg9f4c5r/8/
in visual studio you can also do like that to pass simply or avoiding from comandline argument
static void Main(string[] args)
{
if (args == null)
{
Console.WriteLine("args is null"); // Check for null array
}
else
{
args=new string[2];
args[0] = "welcome in";
args[1] = "www.overflow.com";
Console.Write("args length is ");
Console.WriteLine(args.Length); // Write array length
for (int i = 0; i < args.Length; i++) // Loop through array
{
string argument = args[i];
Console.Write("args index ");
Console.Write(i); // Write index
Console.Write(" is [");
Console.Write(argument); // Write string
Console.WriteLine("]");
}
}
By example:
# select distinct code from Platform where id in ( select platform__id from Build where product=p)
pl_ids = Build.objects.values('platform__id').filter(product=p)
platforms = Platform.objects.values_list('code', flat=True).filter(id__in=pl_ids).distinct('code')
platforms = list(platforms) if platforms else []

When you go to a website, your browser sends a request to the web server including a lot of information. This information might look something like this:
GET /questions/18070154/get-operating-system-info-with-php HTTP/1.1
Host: stackoverflow.com
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate,sdch
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Connection: keep-alive
Cookie: <cookie data removed>
Pragma: no-cache
Cache-Control: no-cache
These information are all used by the web server to determine how to handle the request; the preferred language and whether compression is allowed.
In PHP, all this information is stored in the $_SERVER
array. To see what you're sending to a web server, create a new PHP file and print out everything from the array.
<pre><?php print_r($_SERVER); ?></pre>
This will give you a nice representation of everything that's being sent to the server, from where you can extract the desired information, e.g. $_SERVER['HTTP_USER_AGENT']
to get the operating system and browser.
I had this problem with my datasource in WildFly and Tomcat, connecting to a Oracle 10g.
I found that under certain conditions the statement wasn't closed even when the statement.close() was invoked. The problem was with the Oracle Driver we were using: ojdbc7.jar. This driver is intended for Oracle 12c and 11g, and it seems has some issues when is used with Oracle 10g, so I downgrade to ojdbc5.jar and now everything is running fine.
If on another occasion you're synchronising a Collection rather than a String, perhaps you're be iterating over the collection and are worried about it mutating, Java 5 offers:
Just a simple folder drill down.
sub sample()
Dim FileSystem As Object
Dim HostFolder As String
HostFolder = "C:\"
Set FileSystem = CreateObject("Scripting.FileSystemObject")
DoFolder FileSystem.GetFolder(HostFolder)
end sub
Sub DoFolder(Folder)
Dim SubFolder
For Each SubFolder In Folder.SubFolders
DoFolder SubFolder
Next
Dim File
For Each File In Folder.Files
' Operate on each file
Next
End Sub
Use:
select convert(nvarchar(10), CREATED_TS, 101)
or
select format(cast(CREATED_TS as date), 'MM/dd/yyyy') -- MySQL 3.23 and above
There may not be anything 'Python specific', but the KDE and GNOME desktops offer text-to-speech as a part of their accessibility support, and also offer python library bindings. It may be possible to use the python bindings to control the desktop libraries for text to speech.
If using the Jython implementation of Python on the JVM, the FreeTTS system may be usable.
Finally, OSX and Windows have native APIs for text to speech. It may be possible to use these from python via ctypes or other mechanisms such as COM.
