Even I am using Java 7, maven 2.2.1 and was getting the same error, I removed <scope>tests</scope>
from my pom and used
mvn clean -DskipTests=true install
to successfully build my projects, without upgrading my maven version.
ISO 8601 format (2018-12-23T12:34:56
) is more readable than UNIX timestamp. However on some OSs you cannot have :
in the filenames. Therefore I recommend using something like this instead:
2018-12-23_12-34-56
You can use the following command to get the timestamp in this format:
TIMESTAMP=`date +%Y-%m-%d_%H-%M-%S`
This is the format I have seen many applications use. Another nice thing about this is that if your file names start with this, you can sort them alphabetically and they would be sorted by date.

hope this help others !!
If you cannot change the class under test, then the only option I can suggest is using MS Fakes https://msdn.microsoft.com/en-us/library/hh549175.aspx. However, MS Fakes works only in a few editions of Visual Studio.

I should like to contribute the modern answer. This involves using java.time
, the modern Java date and time API, and not the old Date
nor Calendar
except where there’s no way to avoid it.
Your issue is very likely really a timezone issue. When it is Tue Aug 09 00:00:00 IST 2011, in time zones west of IST midnight has not yet been reached. It is still Aug 8. If for example your API for putting the date into Excel expects UTC, the date will be the day before the one you intended. I believe the real and good solution is to produce a date-time of 00:00 UTC (or whatever time zone or offset is expected and used at the other end).
LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
ZonedDateTime utcDateDime = yourDate.atStartOfDay(ZoneOffset.UTC);
System.out.println(utcDateDime);
This prints
2018-02-27T00:00Z
Z
means UTC (think of it as offset zero from UTC or Zulu time zone). Better still, of course, if you could pass the LocalDate
from the first code line to Excel. It doesn’t include time-of-day, so there is no confusion possible. On the other hand, if you need an old-fashioned Date
object for that, convert just before handing the Date
on:
Date oldfashionedDate = Date.from(utcDateDime.toInstant());
System.out.println(oldfashionedDate);
On my computer this prints
Tue Feb 27 01:00:00 CET 2018
Don’t be fooled, it is correct. My time zone (Central European Time) is at offset +01:00 from UTC in February (standard time), so 01:00:00 here is equal to 00:00:00 UTC. It’s just Date.toString()
grabbing the JVMs time zone and using it for producing the string.
How can I set it to something like 5:30 pm?
To answer your direct question directly, if you have a ZonedDateTime
, OffsetDateTime
or LocalDateTime
, in all of these cases the following will accomplish what you asked for:
yourDateTime = yourDateTime.with(LocalTime.of(17, 30));
If yourDateTime
was a LocalDateTime
of 2018-02-27T00:00
, it will now be 2018-02-27T17:30
. Similarly for the other types, only they include offset and time zone too as appropriate.
If you only had a date, as in the first snippet above, you can also add time-of-day information to it:
LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
LocalDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30));
For most purposes you should prefer to add the time-of-day in a specific time zone, though, for example
ZonedDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30))
.atZone(ZoneId.of("Asia/Kolkata"));
This yields 2018-02-27T17:30+05:30[Asia/Kolkata]
.
Date
and Calendar
vs java.time
The Date
class that you use as well as Calendar
and SimpleDateFormat
used in the other answers are long outdated, and SimpleDateFormat
in particular has proven troublesome. In all cases the modern Java date and time API is so much nicer to work with. Which is why I wanted to provide this answer to an old question that is still being visited.
Link: Oracle Tutorial Date Time, explaining how to use java.time
.
Something like that happened to me when I made copies of structures to temporary tables, so I removed the not null.
DECLARE
CURSOR cur_temp_not_null IS
SELECT table_name, constraint_name FROM all_constraints WHERE table_name LIKE 'TEMP_%' AND owner='myUSUARIO';
V_sql VARCHAR2(200);
BEGIN
FOR c_not_null IN cur_temp_not_null
LOOP
v_sql :='ALTER TABLE ' || c_not_null.table_name || ' DROP CONSTRAINT '|| c_not_null.constraint_name;
EXECUTE IMMEDIATE v_sql;
END LOOP;
END;
when you use camera.open; and you finish using the camera write this commend camera.release(); this will stop the camera so you can use it again
If you need a progmatic solution this should work in jQuery:
$(".abc.xyz").css("width", 200);
Cast the integers to varchar first!
I had been debugging this problem forever - 3 hours 17 mins. What particularly annoyed me was that I already had sql installed on my system through prior uni work but pip/pip3 wasn't recognising it. These threads above and many other I scoured the internet for were helpful in eluminating the problem but didn't actually solve things.
ANSWER
Pip is looking for mysql binaries in the Homebrew Directory which is located relative to Macintosh HD @
/usr/local/Cellar/
so I found that this requires you making a few changes
step 1: Download MySql if not already done so https://dev.mysql.com/downloads/
Step 2: Locate it relative to Macintosh HD and cd
/usr/local/mysql/bin
Step 3: Once there open terminal and use a text editor of choice - I'm a neovim guy myself so I typed (doesn't automatically come with Mac... another story for another day)
nvim mysql_config
Step 4: You will see at approx line 112
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
Change to
# Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
*you'll notice that this file has read-only access so if your using vim or neovim
:w !sudo tee %
Step 5: Head to the home directory and edit the .bash_profile file
cd ~
Then
nvim .bash_profile
and add
export PATH="/usr/local/mysql/bin:$PATH"
to the file then save
Step 6: relative to Macintosh HD locate paths and add to it
cd /private/etc/
then
nvim paths
and add
/usr/local/mysql/bin
*you'll again notice that this file has read-only access so if your using vim or neovim
:w !sudo tee %
then
cd ~
then refresh the terminal with your changes by running
source .bash_profile
Finally
pip3 install mysqlclient
And Viola. Remember it's a vibe.
Here is my way to solve this problem at ubuntu 12.04:
sudo apt-get install build-essential libncursesw5-dev libssl-dev libgdbm-dev libc6-dev libsqlite3-dev tk-dev
Then install the python3 from source code:
wget https://www.python.org/ftp/python/3.4.0/Python-3.4.0.tar.xz
tar xvf Python-3.4.0.tar.xz
cd Python-3.4.0
./configure
make
make test
sudo make install
When you finished installing all of them, pip3 will get installed automatically.
When i use relative path "dir/file.php" with in the header() function in works for me. I think that the session is not saved for some reason when you redirect using the full url...
//Does retain the session info for some reason
header("Location: dir");
//Does not retain the session for some reason
header("Location: https://mywebz.com/dir")

Try to configure the setting of your projects, it is usually due to x86/x64 architecture problems:
Go and set your choice as shown:
Yes.
It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.
The following example will show you the use of multiple classes.
The first class makes the text color
red.
The second class makes the background-color
blue.
See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.
Result: multiple CSS statements in different classes will stack up.
You can read more about CSS Specificity.
.class1 {
color:red;
}
.class2 {
background-color:blue;
}
<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>
if you are getting id from url try
$id = (isset($_GET['id']) ? $_GET['id'] : '');
if getting from form you need to use POST
method cause your form has method="post"
$id = (isset($_POST['id']) ? $_POST['id'] : '');
For php notices use isset()
or empty()
to check values exist or not or initialize variable first with blank or a value
$id= '';
Recursively update Windows 7 until it shows no more updates, using Windows Update check option in Windows 7.
Then download and install Visual C++ Redistributable vc_redist.x64.exe from the Windows website.
Then try to run Apache server.
As mentioned by others there's no cross platform way to do this, but on Windows you can do it like this:
The Code below checks if the key 'A' is down.
if(GetKeyState('A') & 0x8000/*Check if high-order bit is set (1 << 15)*/)
{
// Do stuff
}
In case of shift or similar you will need to pass one of these: https://msdn.microsoft.com/de-de/library/windows/desktop/dd375731(v=vs.85).aspx
if(GetKeyState(VK_SHIFT) & 0x8000)
{
// Shift down
}
The low-order bit indicates if key is toggled.
SHORT keyState = GetKeyState(VK_CAPITAL/*(caps lock)*/);
bool isToggled = keyState & 1;
bool isDown = keyState & 0x8000;
Oh and also don't forget to
#include <Windows.h>
When numbers, dates and times are formatted into strings or parsed from strings a culture is used to determine how it is done. E.g. in the dominant en-US
culture you have these string representations:
In my culture (da-DK
) the values have this string representation:
In the Windows operating system the user may even customize how numbers and date/times are formatted and may also choose another culture than the culture of his operating system. The formatting used is the choice of the user which is how it should be.
So when you format a value to be displayed to the user using for instance ToString
or String.Format
or parsed from a string using DateTime.Parse
or Decimal.Parse
the default is to use the CultureInfo.CurrentCulture
. This allows the user to control the formatting.
However, a lot of string formatting and parsing is actually not strings exchanged between the application and the user but between the application and some data format (e.g. an XML or CSV file). In that case you don't want to use CultureInfo.CurrentCulture
because if formatting and parsing is done with different cultures it can break. In that case you want to use CultureInfo.InvariantCulture
(which is based on the en-US
culture). This ensures that the values can roundtrip without problems.
The reason that ReSharper gives you the warning is that some application writers are unaware of this distinction which may lead to unintended results but they never discover this because their CultureInfo.CurrentCulture
is en-US
which has the same behavior as CultureInfo.InvariantCulture
. However, as soon as the application is used in another culture where there is a chance of using one culture for formatting and another for parsing the application may break.
So to sum it up:
CultureInfo.CurrentCulture
(the default) if you are formatting or parsing a user string.CultureInfo.InvariantCulture
if you are formatting or parsing a string that should be parseable by a piece of software.you are missing fields.iteritems()
in your code.
You could also do it other way, where you get values using keys in the dictionary.
for key in fields:
value = fields[key]
$(this).attr("name")
means the name of the select tag not option name.
To get option name
$("#band_type_choices option:selected").attr('name');

This somehow did the trick for me:
The error tells you that there is an error but you don´t catch it. This is how you can catch it:
getAllPosts().then(response => {
console.log(response);
}).catch(e => {
console.log(e);
});
You can also just put a console.log(reponse)
at the beginning of your API callback function, there is definitely an error message from the Graph API in it.
More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch
Or with async/await:
//some async function
try {
let response = await getAllPosts();
} catch(e) {
console.log(e);
}
I did the following steps to resolve the issue. On the branch which was giving me the error:
git pull origin [branch-name]<current branch>
Thanks all, it was of great help. Just to add more [from MS page]:
Warning
Top-level wildcard bindings (

After looking more, the root element has to be associated with a schema-namespace as Blaise is noting. Yet, I didnt have a package-info java. So without using the @XMLSchema annotation, I was able to correct this issue by using

@XmlType(name = "ns0", namespace = XMLCodeTable.NS1)
@XmlAccessorType(XmlAccessType.NONE)
public class RetrieveMultipleSetsResponse {//...}

This Code also works fine as it just extend the list all the way. Although it is much similar but only have one for loop. So It have less complexity than adding 2 for loops.
Here in my sample I find out the solution of this, because I had the same problem with updates and subquerys:
UPDATE

SET
A.ValueToChange = B.NewValue
FROM

Where
A.Id = B.Id
There are a couple of ways you can do this. Terminal to execute the script:
#!/bin/bash
SCRIPT_PATH="/path/to/script.sh"
# Here you execute your script
"$SCRIPT_PATH"
# or
. "$SCRIPT_PATH"
# or
source "$SCRIPT_PATH"
# or
bash "$SCRIPT_PATH"
# or
eval '"$SCRIPT_PATH"'
# or
OUTPUT=$("$SCRIPT_PATH")
echo $OUTPUT
# or
OUTPUT=`"$SCRIPT_PATH"`
echo $OUTPUT
# or
("$SCRIPT_PATH")
# or
(exec "$SCRIPT_PATH")
All this is correct for the path with spaces!!!
The termination of an array of characters with a null character is just a convention that is specifically for strings in C. You are dealing with something completely different -- an array of character pointers -- so it really has no relation to the convention for C strings. Sure, you could choose to terminate it with a null pointer; that perhaps could be your convention for arrays of pointers. There are other ways to do it. You can't ask people how it "should" work, because you're assuming some convention that isn't there.
you can git fetch nameofremoterepo
, then git log
and personally, I alias gitlog
to git log --graph --oneline --pretty --decorate --all
. try out and see if it fits you
'^(part1|part2|part1,part2)$'
does it work?

The solution is actually a lot easier than any of the other suggestions:
std::wstring stemp = std::wstring(s.begin(), s.end());
LPCWSTR sw = stemp.c_str();
Best of all, it's platform independent.
You need to use the overflow option, but with the following parameters:
.nav {
max-height:300px;
overflow-y:auto;
}
Use overflow-y:auto; so the scrollbar only appears when the content exceeds the maximum height.
If you use overflow-y:scroll, the scrollbar will always be visible - on all .nav - regardless if the content exceeds the maximum heigh or not.
Presumably you want something that adapts itself to the content rather then the the opposite.
Hope it may helpful

const finalData1 = json1.concat(json2).reduce(function (index, obj) {
index[obj.id] = Object.assign({}, obj, index[obj.id]);
return index;
}, []).filter(function (res, obj) {

let hashData = new Map();
json1.concat(json2).forEach(function (obj) {

const finalData2 = Array.from(hashData.values());
I recommend second example , it is faster.
Nto sure which RDBMS you are using, but if it is SQL Server you could look at rather using a CASE statement
Evaluates a list of conditions and returns one of multiple possible result expressions.
The CASE expression has two formats:
The simple CASE expression compares an expression to a set of simple expressions to determine the result.
The searched CASE expression evaluates a set of Boolean expressions to determine the result.
Both formats support an optional ELSE argument.
Fake a request abortion using CURL
setting a low CURLOPT_TIMEOUT_MS
set ignore_user_abort(true)
to keep processing after the connection closed.
With this method no need to implement connection handling via headers and buffer too dependent on OS, Browser and PHP version
Master process
function async_curl($background_process=''){
//-------------get curl contents----------------
$ch = curl_init($background_process);
curl_setopt_array($ch, array(
CURLOPT_HEADER => 0,
CURLOPT_RETURNTRANSFER =>true,
CURLOPT_NOSIGNAL => 1, //to timeout immediately if the value is < 1000 ms
CURLOPT_TIMEOUT_MS => 50, //The maximum number of mseconds to allow cURL functions to execute
CURLOPT_VERBOSE => 1,
CURLOPT_HEADER => 1
));
$out = curl_exec($ch);
//-------------parse curl contents----------------
//$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
//$header = substr($out, 0, $header_size);
//$body = substr($out, $header_size);
curl_close($ch);
return true;
}
async_curl('http://example.com/background_process_1.php');
Background process
ignore_user_abort(true);
//do something...
NB
If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/"feature" on "Unix-like systems" that causes libcurl to timeout immediately if the value is < 1000 ms with the error "cURL Error (28): Timeout was reached". The explanation for this behavior is:
[...]
The solution is to disable signals using CURLOPT_NOSIGNAL

I found best example on Dzone.com which is really helpfull to understand the real different between IOC and DI
“IoC is when you have someone else create objects for you.” So instead of writing "new " keyword (For example, MyCode c=new MyCode())in your code, the object is created by someone else. This ‘someone else’ is normally referred to as an IoC container. It means we handover the rrsponsibility (control )to the container to get instance of object is called Inversion of Control., means instead of you are creating object using new operator, let the container do that for you.
DI(Dependency Injection): Way of injecting properties to an object is
called
Dependency injection.
We have three types of Dependency injection
1) Constructor Injection
2) Setter/Getter Injection
3) Interface Injection
Spring will support only Constructor Injection and Setter/Getter Injection.
If you are sure that you don't have 2FA enabled, you have permission to access the repo, and the repo exists, it's possible that your [email protected] is logged in with another account.
to check that you can do
ssh -T [email protected]
If it shows another account, to resolve this issue:
ssh-add -D
ssh-add ~/.ssh/your_rsa
ssh -T [email protected]
git clone [email protected]:<owner_name>/<repo_name>.git
You can try something like this
IFNULL(NULLIF(X, '' ), 0)
Attribute X is assumed to be empty if it is an empty String, so after that you can declare as a zero instead of last value. In another case, it would remain its original value.
Anyway, just to give another way to do that.
Legacy. List was originally defined to be functional-languages-looking:
1 :: 2 :: Nil // a list
list1 ::: list2 // concatenation of two lists
list match {
case head :: tail => "non-empty"
case Nil => "empty"
}
Of course, Scala evolved other collections, in an ad-hoc manner. When 2.8 came out, the collections were redesigned for maximum code reuse and consistent API, so that you can use ++
to concatenate any two collections -- and even iterators. List, however, got to keep its original operators, aside from one or two which got deprecated.
Here is a simple example of how it works, best practice to put a try\catch into it but for basic use this should do the trick. For this you have a string and file path and apply thus to the FileWriter and the BufferedWriter. This will write "Hello World"(Data variable) and then make a new line. each time this is run it will add the Data variable to the next line.
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
String Data = "Hello World";
File file = new File("C:/Users/stuff.txt");
FileWriter fw = new FileWriter(file,true);
BufferedWriter bw = new BufferedWriter(fw);
bw.write(Data);
bw.newLine();
bw.close();
Just Javascript (as requested)
Add this function somewhere on your page (preferably in the <head>
)
function clearBox(elementID)
{
document.getElementById(elementID).innerHTML = "";
}
Then add the button on click event:
<button onclick="clearBox('cart_item')" />
In JQuery (for reference)
If you prefer JQuery you could do:
$("#cart_item").html("");
In my case I could not load one out of 5 projects in my solution.
It helped to close Visual Studio and I had to delete Microsoft.Net.Compilers.1.3.2
nuget folder under packages
folder.
Afterwards, open your solution again and the project loaded as expected
Just to be sure, close all instances of VS before you delete the folder.
Keeping it simple is the key.
Try Below.
var values = new int[5,7,3];
values = values.OrderBy(p => p).ToList();

definition for mysql_db_container

<= That indicates that mysql will be accessible via port 3307 to the localhost workstation and via port 3306 within the docker net
Run the following to see your container names:
$ dc config --services
mysql_db_container
web
In this case, we have two containers.
If you connect to mysql_db_container
from your localhost workstation and try to access the mysql console there, you'll get that error:
docker-compose run mysql_db_container bash
root@8880ffe47962:/# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
root@8880ffe47962:/# exit
Also, if you try to connect from your local workstation, you'll also get that error:
$ mysql -u root -p -P 3307
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Just add the --protocol=tcp
parameter (otherwise mysql assumes you want to connect via the mysql socket):
$ mysql --protocol=tcp -u root -p -P 3307

You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.
If you give your TD a height of 1px, then the child div would have a heighted parent to calculate it's % from. Because your contents would be larger then 1px, the td would automatically grow, as would the div. Kinda a garbage hack, but I bet it would work.
If you are using python 2.7 or later, the easiest way to do this is to use the subprocess.check_output()
command. Here is an example:
output = subprocess.check_output('ls')
To also redirect stderr you can use the following:
output = subprocess.check_output('ls', stderr=subprocess.STDOUT)
In the case that you want to pass parameters to the command, you can either use a list or use invoke a shell and use a single string.
output = subprocess.check_output(['ls', '-a'])
output = subprocess.check_output('ls -a', shell=True)

The folder containing your Anaconda installation contains a subfolder called conda-meta
with json files for all installed packages, including one for Anaconda itself. Look for anaconda-<version>-<build>.json
.
My file is called anaconda-5.0.1-py27hdb50712_1.json
, and at the bottom is more info about the version:
"installed_by": "Anaconda2-5.0.1-Windows-x86_64.exe",
"link": { "source": "C:\\ProgramData\\Anaconda2\\pkgs\\anaconda-5.0.1-py27hdb50712_1" },

"version": "5.0.1"
(Slightly edited for brevity.)
The output from conda -V
is the conda version.
You can use the RANK function in Excel without necessarily sorting the data. Type =RANK(C2,$C$2:$C$7). Excel will find the relative position of the data in C2 and display the answer. Copy the formula through to C7 by dragging the small node at the right end of the cell cursor.
you can create addHeaderView and use
adapter.addHeaderView(View)
.
This code build the addHeaderView
for more then one header.
the headers should have:
android:layout_height="wrap_content"
public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int TYPE_ITEM = -1;
public class MyViewSHolder extends RecyclerView.ViewHolder {
public MyViewSHolder (View view) {
super(view);
}
// put you code. for example:
View mView;
...

public class ViewHeader extends RecyclerView.ViewHolder {
public ViewHeader(View view) {
super(view);
}
}

public void addHeaderView(View headerView) {

With Pandas version =1.0.0, I would use DataFrame.replace
or Series.replace

df.replace(old_val, pd.NA, inplace=True)
This is better for two reasons:
pd.NA
instead of None
or np.nan
.select 'test', (select name from employee where id=1) as name, (select name from address where id=2) as address ;

return false;
}
or for one:
$.isNumeric($("txtBox").val());
Available with jQuery 1.7.
#php -i | grep php.ini
also will work too!
You could use a list comprehension or a generator expression instead:
', '.join([str(x) for x in list]) # list comprehension
', '.join(str(x) for x in list) # generator expression
Use the preprocessor #
operator:
#define CALL_DO_SOMETHING(VAR) do_something(#VAR, VAR);
If you don't have formatting or formulas you want to keep, you can try saving your file as a tab delimited text file, closing it, and reopening it with excel. This worked for me.
I just give other option for this question - you need to use '.dt' in your code:
import pandas as pd_x000D_
_x000D_
df.index = pd.to_datetime(df.index)_x000D_
_x000D_
#for get year_x000D_
df.index.dt.year_x000D_
_x000D_
#for get month_x000D_
df.index.dt.month_x000D_
_x000D_
#for get day_x000D_
df.index.dt.day_x000D_
_x000D_
#for get hour_x000D_
df.index.dt.hour_x000D_
_x000D_
#for get minute_x000D_
df.index.dt.minute
_x000D_
You've an number of options, depending on how you want to play it:
isNaN(val)
Returns true if val is not a number, false if it is. In your case, this is probably what you need.
isFinite(val)
Returns true if val, when cast to a String, is a number and it is not equal to +/- Infinity
/^\d+$/.test(val)
Returns true if val, when cast to a String, has only digits (probably not what you need).
You are looking for serialize(). Here is an example:
$array = array('foo', 'bar');
//Array to String
$string = serialize($array);
//String to array
$array = unserialize($string);
ul.nav li a, ul.nav li a:visited {
color: #anycolor !important;
}
ul.nav li a:hover, ul.nav li a:active {
color: #anycolor !important;
}
ul.nav li.active a {
color: #anycolor !important;
}
Change the styles as you wish.
Yes you can do it with simple JavaScript snippet:
document.addEventListener('mouseup', event => {
if(window.getSelection().toString().length){
let exactText = window.getSelection().toString();
}
}
Try to use
table {
table-layout: auto;
}
If you use Bootstrap, class table
has table-layout: fixed;
by default.
It was happening to me in ZF2. I was trying to load the Modal content but I forgot to disable the layout before.
So:
$viewModel = new ViewModel();
$viewModel->setTerminal(true);
return $viewModel;
If you want a css only solution you can use active
.crossRotate:active {
transform: rotate(45deg);
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
}
But the transformation will not persist when the activity moves. For that you need javascript (jquery click and css is the cleanest IMO).
$( ".crossRotate" ).click(function() {
if ( $( this ).css( "transform" ) == 'none' ){
$(this).css("transform","rotate(45deg)");
} else {
$(this).css("transform","" );
}
});
Wrapping can be done in various ways. I'll mention 2 of them:
1.) text wrapping - using white-space property http://www.w3schools.com/cssref/pr_text_white-space.asp
2.) word wrapping - using word-wrap property http://webdesignerwall.com/tutorials/word-wrap-force-text-to-wrap
By the way, in order to work using these 2 approaches, I believe you need to set the "display" property to block of the corresponding span element.
However, as Kirill already mentioned, it's a good idea to think about it for a moment. You're talking about forcing the text into a paragraph. PARAGRAPH. That should ring some bells in your head, shouldn't it? ;)
Just to propose a sed
alternative. :) To skip first one million lines, try |sed '1,1000000d'
.
Example:
$ perl -wle 'print for (1..1_000_005)'|sed '1,1000000d'
1000001
1000002
1000003
1000004
1000005
run
runs an imagestart
starts a container.The docker run
doc does mention:
The
docker run
command first creates a writeable container layer over the specified image, and then starts it using the specified command.That is, docker run is equivalent to the API
/containers/create
then/containers/(id)/start
.
You do not run an existing container, you docker exec to it (since docker 1.3).
You can restart an exited container.
def get_pair(line):
key, sep, value = line.strip().partition(" ")
return int(key), value
with open("file.txt") as fd:
d = dict(get_pair(line) for line in fd)
I have actually done this using a bit of sleight of hand: a single lookup table with 16 entries will suffice and all you have to do is break the binary rep into nibbles (4-bit tuples). The complexity is in fact O(1) and I wrote a C++ template which was specialized on the size of the integer you wanted (in # bits)… makes it a constant expression instead of indetermined.
fwiw you can use the fact that (i & -i) will return you the LS one-bit and simply loop, stripping off the lsbit each time, until the integer is zero — but that’s an old parity trick.
JSON in any HTML tag except <script>
tag would be a mere text. Thus it's like you add a story to your HTML page.
However, about formatting, that's another matter. I guess you should change the title of your question.
Here is a small example for those who want to peruse quickly
object ApplyExample01 extends App {
class Greeter1(var message: String) {
println("A greeter-1 is being instantiated with message " + message)
}
class Greeter2 {
def apply(message: String) = {
println("A greeter-2 is being instantiated with message " + message)
}
}
val g1: Greeter1 = new Greeter1("hello")
val g2: Greeter2 = new Greeter2()
g2("world")
}
output
A greeter-1 is being instantiated with message hello
A greeter-2 is being instantiated with message world
For the sake def plot_pca(data):
will work, it is necessary to replace the lines
data_resc, data_orig = PCA(data)
ax1.plot(data_resc[:, 0], data_resc[:, 1], '.', mfc=clr1, mec=clr1)
with lines
newData, data_resc, data_orig = PCA(data)
ax1.plot(newData[:, 0], newData[:, 1], '.', mfc=clr1, mec=clr1)

Please do not ignore nor filter the message, because it is helpfull for people using alternative input methods because of their disability (Like TalkBack, Tecla Access Shield etc etc).
You mus use nvarchar text too. that's mean you have to simply had a "N" before your massive string and that's it! no limitation anymore

Undefined means a variable has been declared but has no value:
var var1;
alert(var1); //undefined

If your project has Roslyn references and you are deploying it on an IIS server, you might get unwanted errors on the website as many hosting providers still have not upgraded their servers and hence do not support Roslyn.
To resolve this issue, you will need to remove the Roslyn compiler from the project template. Removing Roslyn shouldn't affect your code's functionality. It worked fine for me and some other projects (C# 4.5.2) on which I worked.
Do the following steps:
Remove from following Nuget Packages using command line shown below (or you can use GUI of Nuget Package manager by Right Clicking on Root Project Solution and removing them).
PM> Uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform
PM> Uninstall-package Microsoft.Net.Compilers
Remove the following code from your Web.Config file and restart IIS. (Use this method only if step 1 doesn't solve your problem.)
<system.codedom>
<compilers>
<compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
<compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\"Web\" /optionInfer+" />
</compilers>
If you change the classes and load the content within the same function you should be fine.
$(document).ready(function(){
$('.nav li').click(function(event){
//remove all pre-existing active classes
$('.active').removeClass('active');
//add the active class to the link we clicked
$(this).addClass('active');
//Load the content
//e.g.
//load the page that the link was pointing to
//$('#content').load($(this).find(a).attr('href'));
event.preventDefault();
});
});
For each conflicted file you get, you can specify
git checkout --ours -- <paths>
# or
git checkout --theirs -- <paths>
From the git checkout
docs
git checkout [-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...
--ours
--theirs
When checking out paths from the index, check out stage #2 (ours
) or #3 (theirs
) for unmerged paths.The index may contain unmerged entries because of a previous failed merge. By default, if you try to check out such an entry from the index, the checkout operation will fail and nothing will be checked out. Using
-f
will ignore these unmerged entries. The contents from a specific side of the merge can be checked out of the index by using--ours
or--theirs
. With-m
, changes made to the working tree file can be discarded to re-create the original conflicted merge result.
According to the latest Apple Human Interface Guidelines:
In portrait orientation, tab bar icons appear above tab titles. In landscape orientation, the icons and titles appear side-by-side. Depending on the device and orientation, the system displays either a regular or compact tab bar. Your app should include custom tab bar icons for both sizes.
I suggest you to use the above link to understand the full concept. Because apple update it's document in regular interval
Have you tried os.mkdir?
You might also try this little code snippet:
mypath = ...
if not os.path.isdir(mypath):
os.makedirs(mypath)
makedirs creates multiple levels of directories, if needed.
Maven absolutely was designed for this type of dependency.
mvn package
won't install anything in your local repository it just packages the project and leaves it in the target folder.
Do mvn install
in parent project (A), with this all the sub-modules will be installed in your computer's Maven repository, if there are no changes you just need to compile/package the sub-module (B) and Maven will take the already packaged and installed dependencies just right.
You just need to a mvn install
in the parent project if you updated some portion of the code.
change import cv
to import cv2.cv as cv

I am also developing a serial port testing tool using WPF, and I'd like to share some experience of mine.
I think you should refactor your source code according to MVVM design pattern.
At the beginning, I met the same problem as you met, and I solved it using this code:
new Thread(() =>
{
while (...)
{
SomeTextBox.Dispatcher.BeginInvoke((Action)(() => SomeTextBox.Text = ...));
}
}).Start();
This works, but is too ugly. I have no idea how to refactor it, until I saw this: http://www.codeproject.com/Articles/165368/WPF-MVVM-Quick-Start-Tutorial
This is a very kindly step-by-step MVVM tutorial for beginners. No shiny UI, no complex logic, only the basic of MVVM.
newlist = oldlist[::10]
This picks out every 10th element of the list.
I had this issue, jquery URL was valid, everything looked good and validation still worked. After a hard refresh CTL+F5 the error went away in Chrome.
Here is an example
private void doOpenFile() {
int result = myFileChooser.showOpenDialog(this);
if (result == JFileChooser.APPROVE_OPTION) {
Path path = myFileChooser.getSelectedFile().toPath();
try {
String contentString = "";
for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
contentString += s;
}
jText.setText(contentString);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private void doSaveFile() {
int result = myFileChooser.showSaveDialog(this);
if (result == JFileChooser.APPROVE_OPTION) {
// We'll be making a mytmp.txt file, write in there, then move it to
// the selected
// file. This takes care of clearing that file, should there be
// content in it.
File targetFile = myFileChooser.getSelectedFile();
try {
if (!targetFile.exists()) {
targetFile.createNewFile();
}
FileWriter fw = new FileWriter(targetFile);
fw.write(jText.getText());
fw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Workaround I ended up using to avoid all the complexity:
var outputFile = Path.GetTempFileName();
info = new System.Diagnostics.ProcessStartInfo("TheProgram.exe", String.Join(" ", args) + " > " + outputFile + " 2>&1");
info.CreateNoWindow = true;
info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
info.UseShellExecute = false;
System.Diagnostics.Process p = System.Diagnostics.Process.Start(info);
p.WaitForExit();
Console.WriteLine(File.ReadAllText(outputFile)); //need the StandardOutput contents
So I create a temp file, redirect both the output and error to it by using > outputfile > 2>&1
and then just read the file after the process has finished.
The other solutions are fine for scenarios where you want to do other stuff with the output, but for simple stuff this avoids a lot of complexity.
Improved code, using return value of Set#add
instead of comparing the size of list and set.
public static <T> boolean hasDuplicate(Iterable<T> all) {
Set<T> set = new HashSet<T>();
// Set#add returns false if the set does not change, which
// indicates that a duplicate element has been added.
for (T each: all) if (!set.add(each)) return true;
return false;
}
Swift doesn't have its own Date type, but you to use the existing Cocoa NSDate
type, e.g:
class Date {
class func from(year: Int, month: Int, day: Int) -> Date {
let gregorianCalendar = NSCalendar(calendarIdentifier: .gregorian)!
var dateComponents = DateComponents()
dateComponents.year = year
dateComponents.month = month
dateComponents.day = day
let date = gregorianCalendar.date(from: dateComponents)!
return date
}
class func parse(_ string: String, format: String = "yyyy-MM-dd") -> Date {
let dateFormatter = DateFormatter()
dateFormatter.timeZone = NSTimeZone.default
dateFormatter.dateFormat = format
let date = dateFormatter.date(from: string)!
return date
}
}
Which you can use like:
var date = Date.parse("2014-05-20")
var date = Date.from(year: 2014, month: 05, day: 20)
Setting permission to 777 is definitely terrible idea!
... but
If you are getting permission error connected with "storage" folder that's what worked for me:
1) Set "storage" and its subfolders permission to 777 with
sudo chmod -R 777 storage/
2) In browser go to laravel home page laravel/public/ (laravel will create necessary initial storage files)
3) Return safe 775 permission to storage and its subfolders
sudo chmod -R 775 storage/
Regarding this part:
When I convert it to UTF-8 without bom and close file, the file is again ANSI when I reopen.
The easiest solution is to avoid the problem entirely by properly configuring Notepad++.
Try Settings
-> Preferences
-> New document
-> Encoding
-> choose UTF-8
without BOM, and check Apply to opened ANSI files
.
That way all the opened ANSI files will be treated as UTF-8 without BOM.
For explanation what's going on, read the comments below this answer.
To fully learn about Unicode and UTF-8, read this excellent article from Joel Spolsky.
hbn's answer won't work out of the box if the file to load is in a subdirectory or is named with dashes.
In such a case you may consider this alternative :
exec open(myconfig.py).read()
Or the simpler but deprecated in python3 :
execfile(myconfig.py)
I guess Stephan202's warning applies to both options, though, and maybe the loop on lines is safer.
There are 2 possibilities. In either case PyGame has to be initialized by pygame.init
.
import pygame
pygame.init()
Use either the pygame.font
module and create a pygame.font.SysFont
or pygame.font.Font
object. render()
a pygame.Surface
with the text and blit
the Surface to the screen:
my_font = pygame.font.SysFont(None, 50)
text_surface = myfont.render("Hello world!", True, (255, 0, 0))
screen.blit(text_surface, (10, 10))
Or use the pygame.freetype
module. Create a pygame.freetype.SysFont()
or pygame.freetype.Font
object. render()
a pygame.Surface
with the text or directly render_to()
the text to the screen:
my_ft_font = pygame.freetype.SysFont('Times New Roman', 50)
my_ft_font.render_to(screen, (10, 10), "Hello world!", (255, 0, 0))
See also Text and font
Minimal pygame.font
example: repl.it/@Rabbid76/PyGame-Text
import pygame
pygame.init()
window = pygame.display.set_mode((500, 150))
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 100)
text = font.render('Hello World', True, (255, 0, 0))
background = pygame.Surface(window.get_size())
ts, w, h, c1, c2 = 50, *window.get_size(), (128, 128, 128), (64, 64, 64)

for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
window.blit(background, (0, 0))
window.blit(text, text.get_rect(center = window.get_rect().center))
pygame.display.flip()

I usually do something similar to the approach given by How to Use JavaScript to Print a PDF (eHow.com), using an iframe
.
function printTrigger(elementId) {
var getMyFrame = document.getElementById(elementId);
getMyFrame.focus();
getMyFrame.contentWindow.print();
}
(an onClick
on an a
or button
or input
or whatever you wish)
<input type="button" value="Print" onclick="printTrigger('iFramePdf');" />
<iframe id="iFramePdf" src="myPdfUrl.pdf" style="display:none;"></iframe>
Bonus Idea #1 - Create the iframe
and add it to your page within the printTrigger();
so that the PDF isn't loaded until the user clicks your "Print" button, then the javascript can attack! the iframe and trigger the print dialog.
Bonus Idea #2 - Extra credit if you disable your "Print" button and give the user a little loading spinner or something after they click it, so that they know something's in process instead of clicking it repeatedly!
In case of plotting time series, the command ts.plot
requires a different argument than xaxt="n"
require(graphics)
ts.plot(ldeaths, mdeaths, xlab="year", ylab="deaths", lty=c(1:2), gpars=list(xaxt="n"))
axis(1, at = seq(1974, 1980, by = 2))
[Just leaving this here for my own reference.]
My bundle script called git-backup
looks like this
#!/usr/bin/env ruby
if __FILE__ == $0
bundle_name = ARGV[0] if (ARGV[0])
bundle_name = `pwd`.split('/').last.chomp if bundle_name.nil?
bundle_name += ".git.bundle"
puts "Backing up to bundle #{bundle_name}"
`git bundle create /data/Dropbox/backup/git-repos/#{bundle_name} --all`
end
Sometimes I use git backup
and sometimes I use git backup different-name
which gives me most of the possibilities I need.
There have been a few good comments about adding the shebang line to the beginning of the script. I'd like to add a recommendation to use the env command as well, for additional portability.
While #!/bin/bash
may be the correct location on your system, that's not universal. Additionally, that may not be the user's preferred bash. #!/usr/bin/env bash
will select the first bash found in the path.
node v6.6.0
If you just use in development. You can do this:
npm i babel-cli babel-plugin-transform-async-to-generator babel-polyfill --save-dev
the package.json
would be like this:
"devDependencies": {
"babel-cli": "^6.18.0",
"babel-plugin-transform-async-to-generator": "^6.16.0",
"babel-polyfill": "^6.20.0"
}
create .babelrc
file and write this:
{
"plugins": ["transform-async-to-generator"]
}
and then, run your async/await
script like this:
./node_modules/.bin/babel-node script.js
The following code will replace all non ASCII characters with question marks.
"".join([x if ord(x) < 128 else '?' for x in s])
Not with the HTML file control, no. A flash file uploader can do that for you though. You could use some client-side code to check for the PDF extension after they select, but you cannot directly control what they can select.
I think you don't have your permissions set up correctly for /var/www Change the ownership of the folder.

I have aggregated with Qty wise data and store to dataframe
almo_grp_data = pd.DataFrame({'Qty_cnt' :
almo_slt_models_data.groupby( ['orderDate','Item','State Abv']
)['Qty'].sum()}).reset_index()
You can also use Rsync
and find
. For find
:
find $FOLDER -type f | cut -d/ -f2- | sort > /tmp/file_list_$FOLDER
But files with the same names and in the same subfolders, but with different content, will not be shown in the lists.
If you are a fan of GUI, you may check Meld that @Alexander mentioned. It works fine in both windows and linux.
In powershell 5.1 you can actually use install-package, but it can't take extra msi arguments.
install-package .\file.msi
Otherwise with start-process and waiting:
start -wait file.msi ALLUSERS=1,INSTALLDIR=C:\FILE
DO
$do$
BEGIN
IF EXISTS (SELECT FROM orders) THEN
DELETE FROM orders;
ELSE
INSERT INTO orders VALUES (1,2,3);
END IF;
END
$do$
There are no procedural elements in standard SQL. The IF
statement is part of the default procedural language PL/pgSQL. You need to create a function or execute an ad-hoc statement with the DO
command.
You need a semicolon (;
) at the end of each statement in plpgsql (except for the final END
).
You need END IF;
at the end of the IF
statement.
A sub-select must be surrounded by parentheses:
IF (SELECT count(*) FROM orders) > 0 ...
Or:
IF (SELECT count(*) > 0 FROM orders) ...
This is equivalent and much faster, though:
IF EXISTS (SELECT FROM orders) ...
The additional SELECT
is not needed. This does the same, faster:
DO
$do$
BEGIN
DELETE FROM orders;
IF NOT FOUND THEN
INSERT INTO orders VALUES (1,2,3);
END IF;
END
$do$
Though unlikely, concurrent transactions writing to the same table may interfere. To be absolutely sure, write-lock the table in the same transaction before proceeding as demonstrated.

For people still looking for this answer, since configuration.locale
was deprecated from API 24, you can now use:
configuration.setLocale(locale);
Take in consideration that the minSkdVersion for this method is API 17.
Full example code:
@SuppressWarnings("deprecation")
private void setLocale(Locale locale){
SharedPrefUtils.saveLocale(locale); // optional - Helper method to save the selected language to SharedPreferences in case you might need to attach to activity context (you will need to code this)
Resources resources = getResources();
Configuration configuration = resources.getConfiguration();
DisplayMetrics displayMetrics = resources.getDisplayMetrics();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1){
configuration.setLocale(locale);
} else{
configuration.locale=locale;
}
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.N){
getApplicationContext().createConfigurationContext(configuration);
} else {
resources.updateConfiguration(configuration,displayMetrics);
}
}
Don't forget that, if you change the locale with a running Activity, you will need to restart it for the changes to take effect.
EDIT 11th MAY 2018
As from @CookieMonster's post, you might have problems keeping the locale change in higher API versions. If so, add the following code to your Base Activity so that you update the context locale on every Activity creation:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(updateBaseContextLocale(base));
}
private Context updateBaseContextLocale(Context context) {
String language = SharedPrefUtils.getSavedLanguage(); // Helper method to get saved language from SharedPreferences
Locale locale = new Locale(language);
Locale.setDefault(locale);
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.N) {
return updateResourcesLocale(context, locale);
}
return updateResourcesLocaleLegacy(context, locale);
}
@TargetApi(Build.VERSION_CODES.N_MR1)
private Context updateResourcesLocale(Context context, Locale locale) {
Configuration configuration = new Configuration(context.getResources().getConfiguration())
configuration.setLocale(locale);
return context.createConfigurationContext(configuration);

EDIT 7th APRIL 2020
You might be experiencing issues in Android 6 and 7, and this happens due to an issue in the androidx libraries while handling the night mode. For this you will also need to override applyOverrideConfiguration
in your base activity and update the configuration's locale in case a fresh new locale one is created.
Sample code:
@Override
public void applyOverrideConfiguration(Configuration overrideConfiguration) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && Build.VERSION.SDK_INT <= Build.VERSION_CODES.N_MR1) {
// update overrideConfiguration with your locale
setLocale(overrideConfiguration) // you will need to implement this
}
super.applyOverrideConfiguration(overrideConfiguration);
}
I'm sticking with DbVisualizer Free until something better comes along.

The options already listed are very good, however here a few more on this topic that I've researched and came across.
1) http://perfectionkills.com/exploring-canvas-drawing-techniques/
2) http://mcc.id.au/2010/signature.html
3) https://zipso.net/a-simple-touchscreen-sketchpad-using-javascript-and-html5/
And as always you may want to save the canvas to image:

good luck and happy signing
NoClassDefFoundError doesn't give much of a clue as to what went wrong inside the static block. It is good practice to always have a block like this inside of static { ... } initialization code:
static {
try {
... your init code here
} catch (Throwable t) {
LOG.error("Failure during static initialization", t);
throw t;
}
}
Number (1): The IP was incorrect - is the correct answer. The /etc/hosts file (a.k.a. C:\Windows\system32\drivers\etc\hosts ) had an incorrect entry for the local machine name. Corrected the 'hosts' file and Camel runs very well. Thanks for the pointer.
Some tools expect this. For example, wc
expects this:
$ echo -n "Line not ending in a new line" | wc -l
0
$ echo "Line ending with a new line" | wc -l
1
Turns out that to copy a complete directory structure gulp
needs to be provided with a base for your gulp.src()
method.
So gulp.src( [ files ], { "base" : "." })
can be used in the structure above to copy all the directories recursively.
If, like me, you may forget this then try:
gulp.copy=function(src,dest){
return gulp.src(src, {base:"."})
.pipe(gulp.dest(dest));
};
Use the download attribute.
var link = document.createElement('a');
link.href = url;
link.download = 'file.pdf';
link.dispatchEvent(new MouseEvent('click'));
Here's something based on accepted answer. I removed the try/catch to make sure all the exceptions are not swallowed and not dealt with. Also made sure that the return variable (in accepted answer) is never initialized twice for nothing.
public static Nullable<T> ToNullable<T>(this string s) where T: struct
{
if (!string.IsNullOrWhiteSpace(s))
{
TypeConverter conv = TypeDescriptor.GetConverter(typeof(T));
return (T)conv.ConvertFrom(s);
}
return default(Nullable<T>);
}
Other posters gave some examples for situations in which you'd use daemon threads. My recommendation, however, is never to use them.
It's not because they're not useful, but because there are some bad side effects you can experience if you use them. Daemon threads can still execute after the Python runtime starts tearing down things in the main thread, causing some pretty bizarre exceptions.
More info here:
https://joeshaw.org/python-daemon-threads-considered-harmful/

Strictly speaking you never need them, it just makes implementation easier in some cases.
First off, if you're using savefig
, be aware that it will override the figure's background color when saving unless you specify otherwise (e.g. fig.savefig('blah.png', transparent=True)
).
However, to remove the axes' and figure's background on-screen, you'll need to set both ax.patch
and fig.patch
to be invisible.
E.g.
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.plot(range(10))
for item in [fig, ax]:
item.patch.set_visible(False)
with open('test.png', 'w') as outfile:
fig.canvas.print_png(outfile)
(Of course, you can't tell the difference on SO's white background, but everything is transparent...)
If you don't want to show anything other than the line, turn the axis off as well using ax.axis('off')
:
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.plot(range(10))
fig.patch.set_visible(False)
ax.axis('off')
with open('test.png', 'w') as outfile:
fig.canvas.print_png(outfile)
In that case, though, you may want to make the axes take up the full figure. If you manually specify the location of the axes, you can tell it to take up the full figure (alternately, you can use subplots_adjust
, but this is simpler for the case of a single axes).
import matplotlib.pyplot as plt
fig = plt.figure(frameon=False)
ax = fig.add_axes([0, 0, 1, 1])
ax.axis('off')
ax.plot(range(10))
with open('test.png', 'w') as outfile:
fig.canvas.print_png(outfile)
Just adding the #include <math.h>
in c source file and -lm in Makefile at the end will work for me.
gcc -pthread -o p3 p3.c -lm
DateTime
doesn't have a default key as an input. The default key should be an input to the Column
function. Try this:
import datetime
from sqlalchemy import Column, Integer, DateTime
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
class Test(Base):
__tablename__ = 'test'
id = Column(Integer, primary_key=True)
created_date = Column(DateTime, default=datetime.datetime.utcnow)
I'm sorry to disagree, but according to the rules for parsing a legacy color value posted by @Yuhong Bao, chucknorris
DOES NOT equate to #CC0000
, but rather to #C00000
, a very similar but slightly different hue of red. I used the Firefox ColorZilla add-on to verify this.
The rules state:
chucknorris0
chuc knor ris0
ch kn ri
C0 00 00
I was able to use these rules to correctly interpret the following strings:
LuckyCharms
Luck
LuckBeALady
LuckBeALadyTonight
GangnamStyle
UPDATE: The original answerers who said the color was #CC0000
have since edited their answers to include the correction.
Assuming your dataframe is mydf:
mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))
Also, you can use -o
or --offline
in the mvn command line which will put maven in "offline mode" so it won't check for updates. You'll get some warning about not being able to get dependencies not already in your local repo, but no big deal.

Follow the steps mentioned for using support ActionBar in Android Studio(0.4.2) :
Download the Android Support Repository from Android SDK Manager, SDK Manager icon will be available on Android Studio tool bar (or Tools -> Android -> SDK Manager
).
After download you will find your Support repository here
$SDK_DIR\extras\android\m2repository\com\android\support\appcompat-v7
Open your main module's build.gradle file and add following dependency for using action bar in lower API level
dependencies {
compile 'com.android.support:appcompat-v7:+'
}
Sync your project with gradle using the tiny Gradle icon available in toolbar (or Tools -> Android -> Sync Project With Gradle Files
).
There is some issue going on with Android Studio 0.4.2 so check this as well if you face any issue while importing classes in code.
Import Google Play Services library in Android Studio
If Required follow the steps as well :
This is bug in Android Studio 0.4.2 and fixed for Android Studio 0.4.3 release.
I wanted to support a self signed certificate in a Tomcat App but the following snippet failed to work
import java.io.DataOutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class HTTPSPlayground {
public static void main(String[] args) throws Exception {
URL url = new URL("https:// ... .com");
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
httpURLConnection.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());
String serializedMessage = "{}";
wr.writeBytes(serializedMessage);
wr.flush();
wr.close();
int responseCode = httpURLConnection.getResponseCode();
System.out.println(responseCode);
}
}
this is what solved my issue:
.crt
fileecho -n | openssl s_client -connect <your domain>:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/<your domain>.crt
<your domain>
with your domain (e.g. jossef.com
).crt
file in Java's cacerts
certificate storekeytool -import -v -trustcacerts -alias <your domain> -file ~/<your domain>.crt -keystore <JAVA HOME>/jre/lib/security/cacerts -keypass changeit -storepass changeit
<your domain>
with your domain (e.g. jossef.com
)<JAVA HOME>
with your java home directoryEven though iv'e installed my certificate in Java
's default certificate stores, Tomcat ignores that (seems like it's not configured to use Java's default certificate stores).
To hack this, add the following somewhere in your code:
String certificatesTrustStorePath = "<JAVA HOME>/jre/lib/security/cacerts";
System.setProperty("javax.net.ssl.trustStore", certificatesTrustStorePath);
// ...
IMHO it is considered as malformed header data.
You actually want to send those name value pairs as the request content (this is the way POST works) and not as headers.
The second way is true.
I got recently this error and i used the solution which is proposed by @SirPaul. But the error was existing on the other configuration pages of the WordPress like update-core.php
.
The solution that i have found, which resolved all the permission problems, was to deactivate iThemes Security plugin
and update it and reactivate it.
Quick and dirty:
#!/usr/bin/perl -w
use strict;
open(FILE, "</tmp/yourfile.txt") || die "File not found";
my @lines = <FILE>;
close(FILE);
foreach(@lines) {
$_ =~ s/<PREF>/ABCD/g;
}
open(FILE, ">/tmp/yourfile.txt") || die "File not found";
print FILE @lines;
close(FILE);
Perhaps it i a good idea not to write the result back to your original file; instead write it to a copy and check the result first.
Add an :order parameter to the query

does your proxy require you to authenticate? because if it does, you might want you configure your proxy like this.
placeholder names. username is a placeholder for your actual username. password is a placeholder for your actual password. proxy.company.com is a placeholder for your actualy proxy *port" is your actualy port the proxy goes through. its usualy 8080
npm config set proxy "http://username:[email protected]:port"
npm config set https-proxy "http://username:[email protected]:port"
In addition to the still very relevant answer of jujule, I find it quite important to also be aware of the implications of order_by()
on distinct("field_name")
queries. This is, however, a Postgres only feature!
If you are using Postgres and if you define a field name that the query should be distinct for, then order_by()
needs to begin with the same field name (or field names) in the same sequence (there may be more fields afterward).
Note
When you specify field names, you must provide an order_by() in the QuerySet, and the fields in order_by() must start with the fields in distinct(), in the same order.
For example, SELECT DISTINCT ON (a) gives you the first row for each value in column a. If you don’t specify an order, you’ll get some arbitrary row.
If you want to e-g- extract a list of cities that you know shops in , the example of jujule would have to be adapted to this:
# returns an iterable Queryset of cities.
models.Shop.objects.order_by('city').values_list('city', flat=True).distinct('city')
Adding additional information to emboss's answer.
To put it simply, there is an incorrect cert in your certificate chain.
For example, your certificate authority will have most likely given you 3 files.
You most likely combined all of these files into one bundle.
-----BEGIN CERTIFICATE-----
(Your Primary SSL certificate: your_domain_name.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Intermediate certificate: DigiCertCA.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Root certificate: TrustedRoot.crt)
-----END CERTIFICATE-----
If you create the bundle, but use an old, or an incorrect version of your Intermediate Cert (DigiCertCA.crt in my example), you will get the exact symptoms you are describing.
Redownload all certs from your certificate authority and make a fresh bundle.
You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).
See http://api.jquery.com/on/#direct-and-delegated-events
Change your code to
$(document.body).on('click', '.update' ,function(){
The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live
, the jQuery set elements must exist when you execute the code.
As this answers receives a lot of attention, here are two supplementary advises :
1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.
That is, if you're adding an element of class b
to an existing element of id a
, then don't use
$(document.body).on('click', '#a .b', function(){
but use
$('#a').on('click', '.b', function(){
2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c"
would retrieve only one element with this id.
Old post, but I have a solution that could be usefull for next people. Why not just use file length to know what is the progression? Of course, lines has to be almost the same size, but it works very well for big files:
public static void main(String[] args) throws IOException {
File file = new File("yourfilehere");
double fileSize = file.length();
System.out.println("=======> File size = " + fileSize);
InputStream inputStream = new FileInputStream(file);
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "iso-8859-1");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
int totalRead = 0;
try {
while (bufferedReader.ready()) {
String line = bufferedReader.readLine();
// LINE PROCESSING HERE
totalRead += line.length() + 1; // we add +1 byte for the newline char.
System.out.println("Progress ===> " + ((totalRead / fileSize) * 100) + " %");
}
} finally {
bufferedReader.close();
}
}
It allows to see the progression without doing any full read on the file. I know it depends on lot of elements, but I hope it will be usefull :).
[Edition] Here is a version with estimated time. I put some SYSO to show progress and estimation. I see that you have a good time estimation errors after you have treated enough line (I try with 10M lines, and after 1% of the treatment, the time estimation was exact at 95%). I know, some values has to be set in variable. This code is quickly written but has be usefull for me. Hope it will be for you too :).
long startProcessLine = System.currentTimeMillis();
int totalRead = 0;
long progressTime = 0;
double percent = 0;
int i = 0;
int j = 0;
int fullEstimation = 0;
try {
while (bufferedReader.ready()) {
String line = bufferedReader.readLine();
totalRead += line.length() + 1;
progressTime = System.currentTimeMillis() - startProcessLine;
percent = (double) totalRead / fileSize * 100;
if ((percent > 1) && i % 10000 == 0) {
int estimation = (int) ((progressTime / percent) * (100 - percent));
fullEstimation += progressTime + estimation;
j++;
System.out.print("Progress ===> " + percent + " %");
System.out.print(" - current progress : " + (progressTime) + " milliseconds");
System.out.print(" - Will be finished in ===> " + estimation + " milliseconds");
System.out.println(" - estimated full time => " + (progressTime + estimation));
}
i++;
}
} finally {
bufferedReader.close();
}
System.out.println("Ended in " + (progressTime) + " seconds");
System.out.println("Estimative average ===> " + (fullEstimation / j));
System.out.println("Difference: " + ((((double) 100 / (double) progressTime)) * (progressTime - (fullEstimation / j))) + "%");
Feel free to improve this code if you think it's a good solution.
So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:
>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

Three years later, I ran into the same issue. Setting the path in user settings & PATH environment variable didn't help. I updated VSCode and that solved it.
Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:
open(filename, 'w').close()
"No such file or directory" is coming from Linux, and I've seen the following causes:
First cause is not actually having the file inside your container. Some people try to run a command from the host without adding it to their image. Some people shadow their command by mounting a volume on top of the command they wanted to run. If you run the same container, but with a shell instead of your normal entrypoint/cmd value, and run an ls /path/to/cmd
you'll see if this exists.
The next cause is running the wrong command. This often appears with json/exec formatting of the command to run that doesn't parse correctly. If you see a command trying to run ["app",
or something similar, the json string wasn't parsed by Docker and Linux is trying to use a shell to parse the command as a string. This can also happen if you misorder the args, e.g. trying to run -it
is a sign you tried to place flags after the image name when they must be placed before the image name.
With shell scripts, this error appears if the first line with the #!
points to a command that doesn't exist inside the container. For some, this is trying to run bash
in an image that only has /bin/sh
. And in your case, this can be from Windows linefeeds in the script. Switching to Linux/Unix linefeeds in your editor will correct that.
With binaries, this error appears if a linked library is missing. I've seen this often when Go commands that are compiled with libc
, but run on alpine with musl
or scratch without any libraries at all. You need to either include all the missing libraries or statically compile your command. To see these library links, use ldd /your/app
on your binary.
Just use plain objects:
var map = { key1: "value1", key2: "value2" }
function get(k){
return map[k];
}
I know it's a bit old but since I recently looked into it :
let l = UILabel()
l.numberOfLines = 0
l.lineBreakMode = .ByWordWrapping
l.text = "BLAH BLAH BLAH BLAH BLAH"
l.frame.size.width = 300
l.sizeToFit()
First set the numberOfLines property to 0 so that the device understands you don't care how many lines it needs. Then specify your favorite BreakMode Then the width needs to be set before sizeToFit() method. Then the label knows it must fit in the specified width
It looks like you're getting back an array. If it's always going to consist of just one element, you could do this (yes, it's pretty much the same thing as Tomalak's answer):
$.each(result[0], function(key, value){
console.log(key, value);
});
If you might have more than one element and you'd like to iterate over them all, you could nest $.each()
:
$.each(result, function(key, value){
$.each(value, function(key, value){
console.log(key, value);
});
});
I had the same problem, I spent a lot of time searching!
I had the idea to use Eclipse to import the project from GitLab.
Once the project is imported correctly, I made the comparison between the configuration of :
Surprise: The remote does not have the same in both cases. I handed the same as that in eclipse and everything works.
You shouldn't need to configure the consumes or produces attribute at all. Spring will automatically serve JSON based on the following factors.
You should also follow Wim's suggestion and define your controller with the @RestController annotation. This will save you from annotating each request method with @ResponseBody
Another benefit of this approach would be if a client wants XML instead of JSON, they would get it. They would just need to specify xml in the accepts header.
string message = null;

}

You're right that the JetBrains help page isn't very clear. On OS X, you'll want to use the launcher at:
/Applications/PyCharm.app/Contents/MacOS/pycharm
Or, for community edition:
/Applications/PyCharm\ CE.app/Contents/MacOS/pycharm
Unfortunately, adding a symlink to this binary wouldn't work for me (the launcher would crash). Setting an alias worked, though. Add this in your .bash_profile
(or whatever shell you use):
alias pycharm="/Applications/PyCharm CE.app/Contents/MacOS/pycharm"
Then, you can run commands with simply pycharm
.
With this you can do things like open a project:
pycharm ~/repos/my-project
Or open a specific line of a file in a project:
pycharm ~/repos/my-project --line 42 ~/repos/my-project/script.py
Or view the diff of two files (they don't need to be part of a project):
pycharm ~/some_file.txt ~/Downloads/some_other_file.txt
Note that I needed to pass absolute paths to those files or PyCharm couldn't find them..
Also, according to some of the O'Really javascript books....(quoted)
Another reason for using literals as opposed to the Object constructor is that there is no scope resolution. Because it’s possible that you have created a local constructor with the same name, the interpreter needs to look up the scope chain from the place you are calling Object() all the way up until it finds the global Object constructor.
One approach is to strip object and functions from main object. And stringify the simpler form
function simpleStringify (object){
var simpleObject = {};
for (var prop in object ){
if (!object.hasOwnProperty(prop)){
continue;
}
if (typeof(object[prop]) == 'object'){
continue;
}
if (typeof(object[prop]) == 'function'){
continue;
}
simpleObject[prop] = object[prop];
}
return JSON.stringify(simpleObject); // returns cleaned up JSON
};
You can't, you'll have to do something like
<script type="text/javascript">
var php_var = "<?php echo $php_var; ?>";
</script>
You can also load it with AJAX
rhino is right, the snippet lacks of a type for the sake of brevity.
Also, note that if $php_var
has quotes, it will break your script. You shall use addslashes, htmlentities or a custom function.

found interesting cmd in Sed-Onliners - Delete last 3 lines - fnd it perfect for another way to skin the cat (okay not) but idea:
#!/bin/bash
# sed cmd chng #2 to value file wish to retain
cd /opt/depot
ls -1 MyMintFiles*.zip > BigList
sed -n -e :a -e '1,2!{P;N;D;};N;ba' BigList > DeList
for i in `cat DeList`
do
echo "Deleted $i"
rm -f $i
#echo "File(s) gonzo "
#read junk
done
exit 0
REVOKE CONNECT
will not prevent the connections from the db owner or superuser. So if you don't want anyone to connect the db, follow command may be useful.
alter database pilot allow_connections = off;
Then use:
SELECT pg_terminate_backend(pid)
FROM pg_stat_activity
WHERE datname = 'pilot';
$data['title'] = $this->layout->title = 'The Home Page';
$this->layout->content = View::make('home', $data);
I've done this so far because I needed in both the view and master file. It seems if you don't use $this->layout->title it won't be available in the master layout. Improvements welcome!
xcopy "C:\SomeFolderName" "D:\SomeFolderName" /h /i /c /k /e /r /y
Use the above command. It will definitely work.
In this command data will be copied from c:\ to D:\, even folders and system files as well. Here's what the flags do:
/h
copies hidden and system files also/i
if destination does not exist and copying more than one file, assume that destination must be a directory/c
continue copying even if error occurs/k
copies attributes/e
copies directories and subdirectories, including empty ones/r
overwrites read-only files/y
suppress prompting to confirm whether you want to overwrite a fileThe question didn't ask which is fastest, but to add to the sed answer, -n '1p' is badly performing as the pattern space is still scanned on large files. Out of curiosity I found that 'head' wins over sed narrowly:
# best:
head -n1 $bigfile >/dev/null
# a bit slower than head (I saw about 10% difference):
sed '1q' $bigfile >/dev/null
# VERY slow:
sed -n '1p' $bigfile >/dev/null
The hexadecimal value you are looking for is %2B
To get it automatically in PHP run your string through urlencode($stringVal)
. And then run it rhough urldecode($stringVal)
to get it back.
If you want the JavaScript to handle it, use escape( str )
Edit
After @bobince's comment I did more reading and he is correct.
Use encodeURIComponent(str)
and decodeURIComponent(str)
. Escape will not convert the characters, only escape them with \
's
Before doing
git clone https://example.com/root/test.git
make sure that you have added ssh key in your system. Follow this : https://gitlab.com/profile/keys .
Once added run the above command. It will prompt for your gitlab username and password and on authentication, it will be cloned.
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.
the actual index is available as a property of the select element.
var sel = document.getElementById('CCards');
alert(sel.selectedIndex);
you can use the index to get to the selection option, where you can pull the text and value.
var opt = sel.options[sel.selectedIndex];
alert(opt.text);
alert(opt.value);
There isn't a method call, if that's what you're asking for. With a little research, I suppose you could write your own. A particular instance has a fixed sized derived from the number of references and primitive values plus instance bookkeeping data. You would simply walk the object graph. The less varied the row types, the easier.
If that's too slow or just more trouble than it's worth, there's always good old-fashioned row counting rule-of-thumbs.
cmd
Tunnel all your internet traffic through a socks proxy:
netsh winhttp set proxy proxy-server="socks=localhost:9090" bypass-list="localhost"
View the current proxy settings:
netsh winhttp show proxy
Clear all proxy settings:
netsh winhttp reset proxy
In ST2 there's a package you can install called Default FileType which does just that.

I have been working on an open source project that allows you to hot replace classes over and above what hot swap allows: https://github.com/fakereplace/fakereplace
It may or may not work for you, but any feedback is appreciated
This can be done as follows :
select CONVERT(VARCHAR(10), GETDATE(), 103) + ' ' + convert(VARCHAR(8), GETDATE(), 14)
Hope it helps
If you just want to check if the file uploaded is an image you can just try to load it into <img>
tag an check for any error callback.
Example:
var input = document.getElementsByTagName('input')[0];
var reader = new FileReader();
reader.onload = function (e) {
imageExists(e.target.result, function(exists){
if (exists) {
// Do something with the image file..
} else {
// different file format
}
});
};
reader.readAsDataURL(input.files[0]);
function imageExists(url, callback) {
var img = new Image();
img.onload = function() { callback(true); };
img.onerror = function() { callback(false); };
img.src = url;
}
It is mentioned in the .data()
documentation
The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)
This was also covered on Why don't changes to jQuery $.fn.data() update the corresponding html 5 data-* attributes?
The demo on my original answer below doesn't seem to work any more.
Updated answer
Again, from the .data()
documentation
The treatment of attributes with embedded dashes was changed in jQuery 1.6 to conform to the W3C HTML5 specification.
So for <div data-role="page"></div>
the following is true $('div').data('role') === 'page'
I'm fairly sure that $('div').data('data-role')
worked in the past but that doesn't seem to be the case any more. I've created a better showcase which logs to HTML rather than having to open up the Console and added an additional example of the multi-hyphen to camelCase data- attributes conversion.
Also see jQuery Data vs Attr?
HTML
<div id="changeMe" data-key="luke" data-another-key="vader"></div>
<a href="#" id="changeData"></a>
<table id="log">
<tr><th>Setter</th><th>Getter</th><th>Result of calling getter</th><th>Notes</th></tr>
</table>
JavaScript (jQuery 1.6.2+)
var $changeMe = $('#changeMe');
var $log = $('#log');
var logger;
(logger = function(setter, getter, note) {
note = note || '';
eval('$changeMe' + setter);
var result = eval('$changeMe' + getter);
$log.append('<tr><td><code>' + setter + '</code></td><td><code>' + getter + '</code></td><td>' + result + '</td><td>' + note + '</td></tr>');
})('', ".data('key')", "Initial value");
$('#changeData').click(function() {
// set data-key to new value
logger(".data('key', 'leia')", ".data('key')", "expect leia on jQuery node object but DOM stays as luke");
// try and set data-key via .attr and get via some methods
logger(".attr('data-key', 'yoda')", ".data('key')", "expect leia (still) on jQuery object but DOM now yoda");
logger("", ".attr('key')", "expect undefined (no attr <code>key</code>)");
logger("", ".attr('data-key')", "expect yoda in DOM and on jQuery object");
// bonus points
logger('', ".data('data-key')", "expect undefined (cannot get via this method)");
logger(".data('anotherKey')", ".data('anotherKey')", "jQuery 1.6+ get multi hyphen <code>data-another-key</code>");
logger(".data('another-key')", ".data('another-key')", "jQuery < 1.6 get multi hyphen <code>data-another-key</code> (also supported in jQuery 1.6+)");
return false;
});
$('#changeData').click();
Original answer
For this HTML:
<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>
and this JavaScript (with jQuery 1.6.2)
console.log($('#foo').data('helptext'));
$('#changeData').click(function() {
$('#foo').data('helptext', 'Testing 123');
// $('#foo').attr('data-helptext', 'Testing 123');
console.log($('#foo').data('data-helptext'));
return false;
});
Using the Chrome DevTools Console to inspect the DOM, the $('#foo').data('helptext', 'Testing 123');
does not update the value as seen in the Console but $('#foo').attr('data-helptext', 'Testing 123');
does.
You can use:
<asp:textbox id="textBox1" style="text-align:center"></asp:textbox>
Or this:
textbox.Style["text-align"] = "center"; //right, left
FOR the best performance, use specific column name instead of * - for example:
SELECT TOP 1 <columnName>
FROM <tableName>
This is optimal because, instead of returning the whole list of columns, it is returning just one. That can save some time.
Also, returning just first row if there are any values, makes it even faster. Actually you got just one value as the result - if there are any rows, or no value if there is no rows.
If you use the table in distributed manner, which is most probably the case, than transporting just one value from the server to the client is much faster.
You also should choose wisely among all the columns to get data from a column which can take as less resource as possible.
For Web Applications ( ASP.NET MVC and WebForm )
/// <summary>
/// Get current user ip address.
/// </summary>
/// <returns>The IP Address</returns>
public static string GetUserIPAddress()
{
var context = System.Web.HttpContext.Current;
string ip = String.Empty;
if (context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
ip = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
else if (!String.IsNullOrWhiteSpace(context.Request.UserHostAddress))
ip = context.Request.UserHostAddress;
if (ip == "::1")
ip = "127.0.0.1";
return ip;
}
For Windows Applications ( Windows Form, Console, Windows Service , ... )
static void Main(string[] args)
{
HTTPGet req = new HTTPGet();
req.Request("http://checkip.dyndns.org");
string[] a = req.ResponseBody.Split(':');
string a2 = a[1].Substring(1);
string[] a3=a2.Split('<');
string a4 = a3[0];
Console.WriteLine(a4);
Console.ReadLine();
}
Above Spring 4, there is no need to configure MappingJacksonHttpMessageConverter
if you only intend to configure ObjectMapper
.
(configure MappingJacksonHttpMessageConverter
will cause you to lose other MessageConverter)
You just need to do:
public class MyObjectMapper extends ObjectMapper {
private static final long serialVersionUID = 4219938065516862637L;
public MyObjectMapper() {
super();
enable(SerializationFeature.INDENT_OUTPUT);
}
}
And in your Spring configuration, create this bean:
@Bean
public MyObjectMapper myObjectMapper() {
return new MyObjectMapper();
}
For a developer who understands the reason it exists but needs to access an API that doesn't handle OPTIONS calls without auth, I need a temporary answer so I can develop locally until the API owner adds proper SPA CORS support or I get a proxy API up and running.
I found you can disable CORS in Safari and Chrome on a Mac.
Disable same origin policy in Chrome
Chrome: Quit Chrome, open an terminal and paste this command: open /Applications/Google\ Chrome.app --args --disable-web-security --user-data-dir
Safari: Disabling same-origin policy in Safari
If you want to disable the same-origin policy on Safari (I have 9.1.1), then you only need to enable the developer menu, and select "Disable Cross-Origin Restrictions" from the develop menu.
If additional table doesn't fit, you can write your own function for translation.
The plus of sql function over case is, that you can use it in various places, and keep translation logic in one place.
JAVA_HOME needs to point to a JDK home if you're trying to compile code. Check to see if '/usr/tomcat/jre/bin/javac' exists. I doubt it does.
If you don't have a JDK, then you can work around it by getting the ECJ (eclipse compiler) library, dropping it into '~/.ant/lib' and adding a system property to the command-line to use that compiler - check the Ant manual for details.
