Check Screen Options (dropdown tab in the upper right hand corner of the page), and make sure there are sane settings for what to show on screen. All the column settings should be checked, and there should be a positive number of media items being shown on screen.
If that is ok, then check Settings ? Media and make sure that Uploading Files folder is set to wp-content/uploads
.
I believe these are the only settings that can be changed from the administrative screens.
All good answers. To put it in simple language [BCNF] No partial key can depend on a key.
i.e No partial subset ( i.e any non trivial subset except the full set ) of a candidate key can be functionally dependent on some candidate key.
To get the filenames, use:
var files = document.getElementById('inputElementID').files;
Using jQuery (since you already are) you can adapt this to the following:
$('input[type="file"][multiple]').change(
function(e){
var files = this.files;
for (i=0;i<files.length;i++){
console.log(files[i].fileName + ' (' + files[i].fileSize + ').');
}
return false;
});
Printing the STACK trace, logging it or send message to the user, are very bad ways to process the exceptions. Does any one can describe solutions to fix the exception in proper steps then can trying the broken instruction again?
Common Resource Grep (crgrep) will search for string matches in tables/columns by name or content and supports a number of DBs, including SQLServer, Oracle and others. Full wild-carding and other useful options.
It's opensource (I'm the author).
An extremely easy way to do this is by using vim-fugitive. Just open the file in vim, select the line(s) you're interested in using V
, then enter
:Glog
Now you can use :cnext
and :cprev
to see all the revisions of the file where that line is modified. At any point, enter :Gblame
to see the sha, author, and date info.
One more probable cause for the display of this error. The order in which I was creating tables was wrong. I was trying to reference a key from a table that was not yet created.
Why not use PHP! It's all server side:
<?php print file_get_contents("http://foo.com")?>
If you own both sites, you may need to ok this transaction with full declaration of headers at the server end. Works beautifully.
If you are using PHP Xdebug for debugging purpose, remove that file. It worked for me. The response time reduced from 950ms to 125ms.
I found another way to do the type.

I have use the same solution with @Patrick 's answer for years.
It has a small issue when the full path contains symbol-link.
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-builtin-macro-redefined -D'__FILE__=\"$(subst $(realpath ${CMAKE_SOURCE_DIR})/,,$(abspath $<))\"'")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-builtin-macro-redefined -D'__FILE__=\"$(subst $(realpath ${CMAKE_SOURCE_DIR})/,,$(abspath $<))\"'")
-Wno-builtin-macro-redefined
to mute the compiler warnings for redefining __FILE__
macro.
For those compilers do not support this, refer to the Robust way below.
Strip the project path from the file path is your real requirement. You won't like to waste the time to find out where is a header.h
file, src/foo/header.h
or src/bar/header.h
.
We should strip the __FILE__
macro in cmake
config file.
This macro is used in most exists codes. Simply redefine it can set you free.
Compilers like gcc
predefines this macro from the command line arguments. And the full path is written in makefile
s generated by cmake
.
Hard code in CMAKE_*_FLAGS
is required.
There is some commands to add compiler options or definitions in some more recently version, like add_definitions()
and add_compile_definitions()
. These commands will parse the make functions like subst
before apply to source files. That is not we want.
-Wno-builtin-macro-redefined
.include(CheckCCompilerFlag)
check_c_compiler_flag(-Wno-builtin-macro-redefined SUPPORT_C_WNO_BUILTIN_MACRO_REDEFINED)
if (SUPPORT_C_WNO_BUILTIN_MACRO_REDEFINED)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-builtin-macro-redefined")
endif (SUPPORT_C_WNO_BUILTIN_MACRO_REDEFINED)
include(CheckCXXCompilerFlag)
check_cxx_compiler_flag(-Wno-builtin-macro-redefined SUPPORT_CXX_WNO_BUILTIN_MACRO_REDEFINED)
if (SUPPORT_CXX_WNO_BUILTIN_MACRO_REDEFINED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-builtin-macro-redefined")
endif (SUPPORT_CXX_WNO_BUILTIN_MACRO_REDEFINED)
Remember to remove this compiler option from the
set(*_FLAGS ... -D__FILE__=...)
line.
For me, the next way looks pretty intuitive and simple.
zeros = np.zeros((2,1)) #2 is a number of rows in your array.
b = np.hstack((a, zeros))
Try using the data
option of the $.ajax
function. More info here.
$('#btnSaveComments').click(function () {
var comments = $('#txtComments').val();
var selectedId = $('#hdnSelectedId').val();
$.ajax({
url: '<%: Url.Action("SaveComments")%>',
data: { 'id' : selectedId, 'comments' : comments },
type: "post",
cache: false,
success: function (savingStatus) {
$("#hdnOrigComments").val($('#txtComments').val());
$('#lblCommentsNotification').text(savingStatus);
},
error: function (xhr, ajaxOptions, thrownError) {
$('#lblCommentsNotification').text("Error encountered while saving the comments.");
}
});
});
Today (2.5 years after this answer) you can safely use Array.forEach
. As @ricosrealm suggests, decodeURIComponent
was used in this function.
function getJsonFromUrl(url) {
if(!url) url = location.search;
var query = url.substr(1);
var result = {};
query.split("&").forEach(function(part) {
var item = part.split("=");
result[item[0]] = decodeURIComponent(item[1]);
});
return result;
}
actually it's not that simple, see the peer-review in the comments, especially:
=
(@AndrewF)+
(added by me)For further details, see MDN article and RFC 3986.
Maybe this should go to codereview SE, but here is safer and regexp-free code:
function getJsonFromUrl(url) {
if(!url) url = location.href;
var question = url.indexOf("?");
var hash = url.indexOf("#");
if(hash==-1 && question==-1) return {};
if(hash==-1) hash = url.length;
var query = question==-1 || hash==question+1 ? url.substring(hash) :
url.substring(question+1,hash);
var result = {};
query.split("&").forEach(function(part) {
if(!part) return;
part = part.split("+").join(" "); // replace every + with space, regexp-free version
var eq = part.indexOf("=");
var key = eq>-1 ? part.substr(0,eq) : part;
var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
var from = key.indexOf("[");
if(from==-1) result[decodeURIComponent(key)] = val;
else {
var to = key.indexOf("]",from);
var index = decodeURIComponent(key.substring(from+1,to));
key = decodeURIComponent(key.substring(0,from));
if(!result[key]) result[key] = [];
if(!index) result[key].push(val);
else result[key][index] = val;
}
});
return result;
}
This function can parse even URLs like
var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a", "c", "[x]":"b"]}
var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
console.log(key,":",obj[key]);
}
/*
0 : a a
1 : c
[x] : b
*/
It means not to output the respective command. Compare the following two batch files:
@echo foo
and
echo foo
The former has only foo
as output while the latter prints
H:\Stuff>echo foo
foo
(here, at least). As can be seen the command that is run is visible, too.
echo off
will turn this off for the complete batch file. However, the echo off
call itself would still be visible. Which is why you see @echo off
in the beginning of batch files. Turn off command echoing and don't echo the command turning it off.
Removing that line (or commenting it out) is often a helpful debugging tool in more complex batch files as you can see what is run prior to an error message.

Here is a demo: http://jsfiddle.net/YjP4K/
You can do this locally as everyone mentioned using
git checkout -b <branch-name> <sha1-of-commit>
Alternatively, you can do this in github itself, follow the steps:
1- In the repository, click on the Commits
.
2- on the commit you want to branch from, click on <>
to browse the repository at this point in the history.
3- Click on the tree: xxxxxx
in the upper left. Just type in a new branch name there click Create branch xxx
as shown below.
Now you can fetch the changes from that branch locally and continue from there.
do this in two steps:
and use preg_replace
:
$stringWithoutNonLetterCharacters = preg_replace("/[\/\&%#\$]/", "_", $yourString);
$stringWithQuotesReplacedWithSpaces = preg_replace("/[\"\']/", " ", $stringWithoutNonLetterCharacters);
An easy solution to solve this problem is by just adding more seconds to the animation in a:hover
and taking advantage of the transitions in @keyframes
a:hover {
animation: hover 200s infinite alternate ease-in-out;
}
Just make the progression of @keyframes
go faster by using percentages.
@keyframes hover {
0% {
transform: scale(1, 1);
}
1% {
transform: scale(1.1, 1.1);
}
100% {
transform: scale(1.1, 1.1);
}
}
200 seconds or 300 seconds in the animation is more than enough to make sure the animation doesn't restart. A normal person won't last more than a few seconds hovering an image.
You can use text
.
text(x, y, s, fontsize=12)
text
coordinates can be given relative to the axis, so the position of your text will be independent of the size of the plot:
The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords (0,0 is lower-left and 1,1 is upper-right). The example below places text in the center of the axes::
text(0.5, 0.5,'matplotlib',
horizontalalignment='center',
verticalalignment='center',
transform = ax.transAxes)
To prevent the text to interfere with any point of your scatter is more difficult afaik. The easier method is to set y_axis (ymax in ylim((ymin,ymax))
) to a value a bit higher than the max y-coordinate of your points. In this way you will always have this free space for the text.
EDIT: here you have an example:
In [17]: from pylab import figure, text, scatter, show
In [18]: f = figure()
In [19]: ax = f.add_subplot(111)
In [20]: scatter([3,5,2,6,8],[5,3,2,1,5])
Out[20]: <matplotlib.collections.CircleCollection object at 0x0000000007439A90>
In [21]: text(0.1, 0.9,'matplotlib', ha='center', va='center', transform=ax.transAxes)
Out[21]: <matplotlib.text.Text object at 0x0000000007415B38>
In [22]:
The ha and va parameters set the alignment of your text relative to the insertion point. ie. ha='left' is a good set to prevent a long text to go out of the left axis when the frame is reduced (made narrower) manually.

I think JSONQuery is a superset of JSONPath and thus replaces it in dojo. Then there's also RQL.
From Dojo documentation:
JSONQuery is an extended version of JSONPath with additional features for security, ease of use, and a comprehensive set of data querying tools including filtering, recursive search, sorting, mapping, range selection, and flexible expressions with wildcard string comparisons and various operators.
JSONselect has another point of view on the question (CSS selector-like, rather than XPath) and has a JavaScript implementation.
Just add throw
where needed, and try
block to the caller that handles the error. By convention you should only throw things that derive from std::exception
, so include <stdexcept>
first.
int compare(int a, int b) {
if (a < 0 || b < 0) {
throw std::invalid_argument("a or b negative");
}
}
void foo() {
try {
compare(-1, 0);
} catch (const std::invalid_argument& e) {
// ...
}
}
Also, look into Boost.Exception.
If the caption box is gray then you can try wrapping the image and the caption in a div with the same background color of gray---so a "div" tag before the "tr" tag...This will mask the gap because instead of being white, it will be gray and look like part of the gray caption.
I don't know Mathematica . . . too bad. But I like the answer above, for the most part.
Still there is a major flaw in relying on the stripes alone to glean the answer (I personally don't have a problem with one manual adjustment). There is an example (listed by Brett Champion, here) presented which shows that they, at times, break up the shirt pattern. So then it becomes a more complex pattern.
I would try an approach of shape id and colors, along with spacial relations. Much like face recognition, you could look for geometric patterns at certain ratios from each other. The caveat is that usually one or more of those shapes is occluded.
Get a white balance on the image, and red a red balance from the image. I believe Waldo is always the same value/hue, but the image may be from a scan, or a bad copy. Then always refer to an array of the colors that Waldo actually is: red, white, dark brown, blue, peach, {shoe color}.
There is a shirt pattern, and also the pants, glasses, hair, face, shoes and hat that define Waldo. Also, relative to other people in the image, Waldo is on the skinny side.
So, find random people to obtain an the height of people in this pic. Measure the average height of a bunch of things at random points in the image (a simple outline will produce quite a few individual people). If each thing is not within some standard deviation from each other, they are ignored for now. Compare the average of heights to the image's height. If the ratio is too great (e.g., 1:2, 1:4, or similarly close), then try again. Run it 10(?) of times to make sure that the samples are all pretty close together, excluding any average that is outside some standard deviation. Possible in Mathematica?
This is your Waldo size. Walso is skinny, so you are looking for something 5:1 or 6:1 (or whatever) ht:wd. However, this is not sufficient. If Waldo is partially hidden, the height could change. So, you are looking for a block of red-white that ~2:1. But there has to be more indicators.
Any of those could apply. These are also negative checks against similar people in the pic -- e.g., #2 negates wearing a red-white apron (too close to shoes), #5 eliminates light colored hair. Also, shape is only one indicator for each of these tests . . . color alone within the specified distance can give good results.
This will narrow down the areas to process.
Storing these results will produce a set of areas that should have Waldo in it. Exclude all other areas (e.g., for each area, select a circle twice as big as the average person size), and then run the process that @Heike laid out with removing all but red, and so on.
Any thoughts on how to code this?
Edit:
Thoughts on how to code this . . . exclude all areas but Waldo red, skeletonize the red areas, and prune them down to a single point. Do the same for Waldo hair brown, Waldo pants blue, Waldo shoe color. For Waldo skin color, exclude, then find the outline.
Next, exclude non-red, dilate (a lot) all the red areas, then skeletonize and prune. This part will give a list of possible Waldo center points. This will be the marker to compare all other Waldo color sections to.
From here, using the skeletonized red areas (not the dilated ones), count the lines in each area. If there is the correct number (four, right?), this is certainly a possible area. If not, I guess just exclude it (as being a Waldo center . . . it may still be his hat).
Then check if there is a face shape above, a hair point above, pants point below, shoe points below, and so on.

which git &> /dev/null || { echo >&2 "I require git but it's not installed. Aborting."; exit 1; }
echo "Git is installed."
That will echo "Git is installed" if it is, otherwise, it'll echo an error message. You can use this for scripts that use git
It's also customizable, so you can change "which git" to "which java" or something, and change the error message.

To clarify some points:
As jro has mentioned, the right way is to use subprocess.communicate
.
Yet, when feeding the stdin
using subprocess.communicate
with input
, you need to initiate the subprocess with stdin=subprocess.PIPE
according to the docs.
Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.
Also qed has mentioned in the comments that for Python 3.4 you need to encode the string, meaning you need to pass Bytes to the input
rather than a string
. This is not entirely true. According to the docs, if the streams were opened in text mode, the input should be a string (source is the same page).
If streams were opened in text mode, input must be a string. Otherwise, it must be bytes.
So, if the streams were not opened explicitly in text mode, then something like below should work:
import subprocess
command = ['myapp', '--arg1', 'value_for_arg1']
p = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
output = p.communicate(input='some data'.encode())[0]
I've left the stderr
value above deliberately as STDOUT
as an example.
That being said, sometimes you might want the output of another process rather than building it up from scratch. Let's say you want to run the equivalent of echo -n 'CATCH\nme' | grep -i catch | wc -m
. This should normally return the number characters in 'CATCH' plus a newline character, which results in 6. The point of the echo here is to feed the CATCH\nme
data to grep. So we can feed the data to grep with stdin in the Python subprocess chain as a variable, and then pass the stdout as a PIPE to the wc
process' stdin (in the meantime, get rid of the extra newline character):
import subprocess
what_to_catch = 'catch'
what_to_feed = 'CATCH\nme'
# We create the first subprocess, note that we need stdin=PIPE and stdout=PIPE
p1 = subprocess.Popen(['grep', '-i', what_to_catch], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
# We immediately run the first subprocess and get the result
# Note that we encode the data, otherwise we'd get a TypeError
p1_out = p1.communicate(input=what_to_feed.encode())[0]
# Well the result includes an '\n' at the end,
# if we want to get rid of it in a VERY hacky way
p1_out = p1_out.decode().strip().encode()
# We create the second subprocess, note that we need stdin=PIPE
p2 = subprocess.Popen(['wc', '-m'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
# We run the second subprocess feeding it with the first subprocess' output.
# We decode the output to convert to a string
# We still have a '\n', so we strip that out
output = p2.communicate(input=p1_out)[0].decode().strip()
This is somewhat different than the response here, where you pipe two processes directly without adding data directly in Python.
Hope that helps someone out.
Have a look at the ReadAsset.java from API samples that come with the SDK.
try {
InputStream is = getAssets().open("read_asset.txt");
// We guarantee that the available method returns the total
// size of the asset... of course, this does mean that a single
// asset can't be more than 2 gigs.
int size = is.available();
// Read the entire asset into a local byte buffer.
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
// Convert the buffer into a string.
String text = new String(buffer);
// Finally stick the string into the text view.
TextView tv = (TextView)findViewById(R.id.text);
tv.setText(text);
} catch (IOException e) {
// Should never happen!
throw new RuntimeException(e);

Orabig is correct.
You can bind 10.0.2.15 in Ubuntu (VirtualBox) then do a port forwarding from host to guest Ubuntu.
in /etc/redis/redis.conf
bind 10.0.2.15
then, restart redis:
sudo systemctl restart redis
It shall work!
A more optimized way in mysql for this purpose*:
SELECT columnName DIV 1 AS columnName, moreColumns, etc
FROM myTable
WHERE ...
Using DIV 1 is a huge speed improvement over FLOOR, not to mention string based functions like FORMAT
mysql> SELECT BENCHMARK(10000000,1234567 DIV 7) ;
+-----------------------------------+
| BENCHMARK(10000000,1234567 DIV 7) |
+-----------------------------------+
| 0 |
+-----------------------------------+
1 row in set (0.83 sec)
mysql> SELECT BENCHMARK(10000000,1234567 / 7) ;
+---------------------------------+
| BENCHMARK(10000000,1234567 / 7) |
+---------------------------------+
| 0 |
+---------------------------------+
1 row in set (7.26 sec)
mysql> SELECT BENCHMARK(10000000,FLOOR(1234567 / 7)) ;

| BENCHMARK(10000000,FLOOR(1234567 / 7)) |
+----------------------------------------+
| 0 |
+----------------------------------------+
1 row in set (8.80 sec)
(*) NOTE: As pointed by Grbts, be aware of the behaviour of DIV 1 when used with non unsigned/positive values.
Append a \r\n
to the string to put the text on a new line.
textBox1.Text += ("brown\r\n");
textBox1.Text += ("brwn");
This will produce the two entries on separate lines.
You can define a a click function and then set the onclick
attribute for the element.
function imageClick(url) {
window.location = url;
}
<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" onclick="imageClick('../images/bottle.html')" />
This approach lets you get rid of the surrounding <a>
element. If you want to keep it, then define the onclick
attribute on <a>
instead of on <img>
.

To return None
if there is no such element:
next((x for x in seq if predicate(x)), None)
Or:
next(filter(predicate, seq), None)
As Character is a class deriving from Object, you can assign null as "instance":
Character myChar = null;
Problem solved ;)
Regarding apply
vs map
:
pool.apply(f, args)
: f
is only executed in ONE of the workers of the pool. So ONE of the processes in the pool will run f(args)
.
pool.map(f, iterable)
: This method chops the iterable into a number of chunks which it submits to the process pool as separate tasks. So you take advantage of all the processes in the pool.
Try this command:
git ls-files
This lists all of the files in the repository, including those that are only staged but not yet committed.

This is a "roundabout" solution but you could use ipython
Start ipython notebook from terminal:
$ ipython notebook
It will open in a browser where you can run the javascript
You can use use findFragmentById
in FragmentManager
.
Since you are using the Support library (you are extending FragmentActivity) you can use:
getSupportFragmentManager().findFragmentById(R.id.pageview)
If you are not using the support library (so you are on Honeycomb+ and you don't want to use the support library):
getFragmentManager().findFragmentById(R.id.pageview)
Please consider that using the support library is recommended even on Honeycomb+.
You can also use defaultdict to address this situation. It goes something like this:
from collections import defaultdict
#initialises the dictionary with values as list
aTargetDictionary = defaultdict(list)
for aKey in aSourceDictionary:
aTargetDictionary[aKey].append(aSourceDictionary[aKey])
You are not evaluating a condition for the IF. I am guessing you want to not copy if you find stringToCheck in fileToCheck. You need to do something like (code untested but you get the idea):
CD C:\MyFolder
findstr /c:"stringToCheck" fileToCheck.bat
IF NOT ERRORLEVEL 0 XCOPY "C:\OtherFolder\fileToCheck.bat" "C:\MyFolder" /s /y
EDIT by dbenham
The above test is WRONG, it always evaluates to FALSE.
The correct test is IF ERRORLEVEL 1 XCOPY ...
Update: I can't test the code, but I am not sure what return value findstr actually returns if it doesn't find anything. You might have to do something like:
CD C:\MyFolder
findstr /c:"stringToCheck" fileToCheck.bat > tempfindoutput.txt
set /p FINDOUTPUT= < tempfindoutput.txt
IF "%FINDOUTPUT%"=="" XCOPY "C:\OtherFolder\fileToCheck.bat" "C:\MyFolder" /s /y
del tempfindoutput.txt
A void* can point to anything (it's a raw pointer without any type info).
There is a way:
$value = json_decode(json_encode($value, JSON_NUMERIC_CHECK|JSON_PRESERVE_ZERO_FRACTION|JSON_UNESCAPED_SLASHES), true);
Using is_*
won't work, since the variable
is a: string
.
Using the combination of json_encode()
and then json_decode()
it's converted to it's "true" form. If it's a true string
then it would output wrong.
$num = "Me";
$int = (int)$num;
$float = (float)$num;
var_dump($num, $int, $float);
Will output: string(2) "Me" int(0) float(0)
I would Use Hostname -L
to get just the IP to use as a variable in a script.
The major difference between Page_Load
and Page_PreRender
is that in the Page_Load method not all of your page controls are completely initialized (loaded), because individual controls Load()
methods has not been called yet. This means that tree is not ready for rendering yet. In Page_PreRender
you guaranteed that all page controls are loaded and ready for rendering. Technically Page_PreRender
is your last chance to tweak the page before it turns into HTML stream.
It would be the former. Go by extensions as well instead of folder structure.

Update
I thought I'd provide an update from the comments below. Although not directly answering the OP's question, see the following for more examples of .gitignore
syntax.
Community wiki (constantly being updated):
.gitignore for Visual Studio Projects and Solutions
More examples with specific language use can be found here (thanks to Chris McKnight's comment):
Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.
try this:
@echo off 2>Nul 3>Nul 4>Nul
ben ali
mubarak
gadeffi
..next ?
echo hello Tunisia
pause
You can also use binding
<TextBlock Text="{Binding MyText}"/>
And set MyText like this:
Public string MyText
{
get{return string.Format("My Text \n Your Text");}
}
Not true for the OP, but this error can be caused by using single quotation marks ('
) instead of double ("
) for strings.
The JSON spec requires double quotation marks for strings.
E.g:
JSON.parse(`{"myparam": 'myString'}`)
gives the error, whereas
JSON.parse(`{"myparam": "myString"}`)
does not. Note the quotation marks around myString
.
This might work?
Comparator mycomparator =
Collections.reverseOrder(Collections.reverseOrder());
You could use a label and a goto
, but this is a bad hack. You should consider moving some of the stuff in your if statement to separate methods.
Use the aggregate MAX(signin)
grouped by id. This will list the most recent signin
for each id
.
SELECT
id,
MAX(signin) AS most_recent_signin
FROM tbl
GROUP BY id
To get the whole single record, perform an INNER JOIN
against a subquery which returns only the MAX(signin)
per id.
SELECT
tbl.id,
signin,
signout
FROM tbl
INNER JOIN (
SELECT id, MAX(signin) AS maxsign FROM tbl GROUP BY id
) ms ON tbl.id = ms.id AND signin = maxsign
WHERE tbl.id=1
Well, if you have a number like 0.123456
that is the result of a division to give a percentage, multiply it by 100 and then either round it or use toFixed
like in your example.
Math.round(0.123456 * 100) //12
Here is a jQuery plugin to do that:
jQuery.extend({
percentage: function(a, b) {
return Math.round((a / b) * 100);
}
});
Usage:
alert($.percentage(6, 10));
Empty
refers to a variable being at its default value. So if you check if a cell with a value of 0 = Empty
then it would return true.
IsEmpty
refers to no value being initialized.
In a nutshell, if you want to see if a cell is empty (as in nothing exists in its value) then use IsEmpty
. If you want to see if something is currently in its default value then use Empty
.
Margin="1,2,3,4"
It is also possible to specify just two sizes like this:
Margin="1,2"
Finally you can specify a single size:
Margin="1"
The order is the same as in WinForms.
You can find a recent servlet-api.jar in Tomcat 6 or 7 lib directory. If you don't have Tomcat on your machine, download the binary distribution of version 6 or 7 from http://tomcat.apache.org/download-70.cgi
More clarified version of above answers:
IEnumerable<IGrouping<int, ClassA>> groups = list.GroupBy(x => x.PropertyIntOfClassA);
foreach (var groupingByClassA in groups)
{
int propertyIntOfClassA = groupingByClassA.Key;
//iterating through values
foreach (var classA in groupingByClassA)
{
int key = classA.PropertyIntOfClassA;
}
}
If you want to remove multiple objects that are matching to the property try this.
I have used following code to remove element from object array it helped me.
In general an object can be removed in two ways from an ArrayList
(or generally any List), by index
(remove(int)) and by object
(remove(Object)).
some time for you arrayList.remove(index)
or arrayList.remove(obj.get(index))
using these lines may not work try to use following code.
for (Iterator<DetailInbox> iter = detailInboxArray.iterator(); iter.hasNext(); ) {
DetailInbox element = iter.next();
if (element.isSelected()) {
iter.remove();
}
}
The boost
filesystem
library is also available as the experimental/filesystem
library and was merged into ISO C++ for C++17. You can use it like this:
#include <iostream>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;
int main () {
std::cout << fs::path("/foo/bar.txt").filename() << '\n'
}
Output:
"bar.txt"
It also works for std::string
objects.
Try SuperPuTTY. It is similar to puttycm.
only variable/object declaration statement are written outside of method
public class details{
public static void main(String arg[]){
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);
}
}
here is example try to learn java book and see the syntax then try to develop the program
Copy the ROOT (Default) Web App into Eclipse.
Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace.
To me, the issue was due to wrong imports. In fact, one need to update the imports after adding the v7 support library.
It can be fixed by doing as follows, for each class of your project:
import android.[*]
, in each classandroid.support.[*]
(and not android.[*]
).You can add values to the HttpWebRequest.Headers collection.
According to MSDN, it should be supported in windows phone: http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.headers%28v=vs.95%29.aspx
Or you can use the function below for removing non-ascii character from the string. You will get know internal working.
private static String removeNonASCIIChar(String str) {
StringBuffer buff = new StringBuffer();
char chars[] = str.toCharArray();
for (int i = 0; i < chars.length; i++) {
if (0 < chars[i] && chars[i] < 127) {
buff.append(chars[i]);
}
}
return buff.toString();
}
(cd dir && ls)
will only output filenames in dir. Use ls -1
if you want one per line.
(Changed ; to && as per Sactiw's comment).
I haven't tested this - but it should give you a general idea of the direction you need to take.
For this to work, I'm going to assume a few things about the text of the TextView
:
TextView
consists of lines delimited with "\n"
.TextView
which will all include one operator and one number.Char
of a line.First we get the text:
String input = tv1.getText().toString();
Then we split it up for each line:
String[] lines = input.split( "\n" );
Now we need to calculate the total value:
int total = Integer.parseInt( lines[0].trim() ); //We know this is a number.
for( int i = 1; i < lines.length(); i++ ) {
total = calculate( lines[i].trim(), total );
}
The method calculate should look like this, assuming that we know the first Char
of a line is the operator:
private int calculate( String input, int total ) {
switch( input.charAt( 0 ) )
case '+':
return total + Integer.parseInt( input.substring( 1, input.length() );
case '-':
return total - Integer.parseInt( input.substring( 1, input.length() );
case '*':
return total * Integer.parseInt( input.substring( 1, input.length() );
case '/':
return total / Integer.parseInt( input.substring( 1, input.length() );
}
EDIT
So the above as stated in the comment below does "left-to-right" calculation, ignoring the normal order ( + and / before + and -).
The following does the calculation the right way:
String input = tv1.getText().toString();
input = input.replace( "\n", "" );
input = input.replace( " ", "" );
int total = getValue( input );
The method getValue
is a recursive method and it should look like this:
private int getValue( String line ) {
int value = 0;
if( line.contains( "+" ) ) {
String[] lines = line.split( "\\+" );
value += getValue( lines[0] );
for( int i = 1; i < lines.length; i++ )
value += getValue( lines[i] );
return value;
}
if( line.contains( "-" ) ) {
String[] lines = line.split( "\\-" );
value += getValue( lines[0] );
for( int i = 1; i < lines.length; i++ )
value -= getValue( lines[i] );
return value;
}
if( line.contains( "*" ) ) {
String[] lines = line.split( "\\*" );
value += getValue( lines[0] );
for( int i = 1; i < lines.length; i++ )
value *= getValue( lines[i] );
return value;
}
if( line.contains( "/" ) ) {
String[] lines = line.split( "\\/" );
value += getValue( lines[0] );
for( int i = 1; i < lines.length; i++ )
value /= getValue( lines[i] );
return value;
}
return Integer.parseInt( line );
}
Special cases that the recursive method does not handle:
Also the fact the we're using Integers
might give some "odd" results in some cases as e.g. 5/3 = 1.
You can use CSS to set the opacity, and than use javascript to apply the styles to a certain element in the DOM.
.opClass {
opacity:0.4;
filter:alpha(opacity=40); /* For IE8 and earlier */
}
Than use (for example) jQuery to change the style:
$('#element_id').addClass('opClass');
Or with plain javascript, like this:
document.getElementById("element_id").className = "opClass";
I have created this easy to use library that does exactly what you are looking for: ss-search
import { search } from "ss-search"
const data = [
{
"foo" : "bar",
"bar" : "sit"
},
{
"foo" : "lorem",
"bar" : "ipsum"
},
{
"foo" : "dolor",
"bar" : "amet"
}
]
const searchKeys = ["foor", "bar"]
const searchText = "dolor"
const results = search(data, keys, searchText)
// results: [{ "foo": "dolor", "bar": "amet" }]
Use JSON.stringify(<data>)
.
Change your code: data: sendInfo
to data: JSON.stringify(sendInfo)
.
Hope this can help you.
The entire confusion is caused since Google chose non-intuivitive names instead of something as follows:
onCreateAndPrepareToDisplay() [instead of onCreate() ]
onPrepareToDisplay() [instead of onRestart() ]
onVisible() [instead of onStart() ]
onBeginInteraction() [instead of onResume() ]
onPauseInteraction() [instead of onPause() ]
onInvisible() [instead of onStop]
onDestroy() [no change]
The Activity Diagram can be interpreted as:
Some ideas:
Use git mergetool
to split the merge files into original and new parts. Hopefully one of those is the file with your non-stash changes in it.
Apply the diff of the stash in reverse, to undo just those changes. You'll probably have to manually split out the files with the merge conflicts (which hopefully the above trick will work for).
I didn't test either of these, so I don't know for sure of they will work.
Not sure if this is what you're referring to, but this is the list of HTML entities you can use:
List of XML and HTML character entity references
Using the content within the 'Name' column you can just wrap these in an &
and ;
E.g.
,  
, etc.
In Python3, csv.reader
expects, that passed iterable returns strings, not bytes. Here is one more solution to this problem, that uses codecs
module:
import csv
import codecs
ifile = open('sample.csv', "rb")
read = csv.reader(codecs.iterdecode(ifile, 'utf-8'))
for row in read :
print (row)
/dev/tty
is a synonym for the controlling terminal (if any) of the current process. As jtl999 says, it's a character special file; that's what the c
in the ls -l
output means.
man 4 tty
or man -s 4 tty
should give you more information, or you can read the man page online here.
Incidentally, pwd > /dev/tty
doesn't necessarily print to the shell's stdout (though it is the pwd
command's standard output). If the shell's standard output has been redirected to something other than the terminal, /dev/tty
still refers to the terminal.
You can also read from /dev/tty
, which will normally read from the keyboard.
In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.
def change change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13 change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13 end
It because every time
void pthread_exit(void *ret);
will be called from thread function so which ever you want to return simply its pointer pass with pthread_exit().
Now at
int pthread_join(pthread_t tid, void **ret);
will be always called from where thread is created so here to accept that returned pointer you need double pointer ..
i think this code will help you to understand this
#include <stdio.h>
#include <string.h>
#include <pthread.h>
#include <stdlib.h>
void* thread_function(void *ignoredInThisExample)
{
char *a = malloc(10);
strcpy(a,"hello world");
pthread_exit((void*)a);
}
int main()
{
pthread_t thread_id;
char *b;
pthread_create (&thread_id, NULL,&thread_function, NULL);
pthread_join(thread_id,(void**)&b); //here we are reciving one pointer
value so to use that we need double pointer
printf("b is %s\n",b);
free(b); // lets free the memory
}
find
already looks recursively by default:
[15:21:53 ~]$ mkdir foo
[15:22:28 ~]$ cd foo
[15:22:31 ~/foo]$ mkdir bar
[15:22:35 ~/foo]$ cd bar
[15:22:36 ~/foo/bar]$ ln -s ../foo abc
[15:22:40 ~/foo/bar]$ cd ..
[15:22:47 ~/foo]$ ln -s foo abc
[15:22:52 ~/foo]$ find ./ -type l
.//abc
.//bar/abc
[15:22:57 ~/foo]$
Use this JsonKnownTypes, it's very similar way to use, it just add discriminator to json:
[JsonConverter(typeof(JsonKnownTypeConverter<BaseClass>))]
[JsonKnownType(typeof(Base), "base")]
[JsonKnownType(typeof(Derived), "derived")]
public class Base
{
public string Name;
}
public class Derived : Base
{
public string Something;
}
Now when you serialize object in json will be add "$type"
with "base"
and "derived"
value and it will be use for deserialize
Serialized list example:
[
{"Name":"some name", "$type":"base"},
{"Name":"some name", "Something":"something", "$type":"derived"}
]
I was bored and playing around JSPerf trying to beat the currently selected answer prepending a zero no matter what and using slice(-2)
. It's a clever approach but the performance gets a lot worse as the string gets longer.
For numbers zero to ten (one and two character strings) I was able to beat by about ten percent, and the fastest approach was much better when dealing with longer strings by using charAt
so it doesn't have to traverse the whole string.
This follow is not quit as simple as slice(-2)
but is 86%-89% faster when used across mostly 3 digit numbers (3 character strings).
var prepended = ( 1 === string.length && string.charAt( 0 ) !== "0" ) ? '0' + string : string;
