I think the answers above are missing a simple approach that I've found very useful.
When I have a file that is too large to load in memory, I break up the file into multiple smaller files (either by row or cols)
Example: In case of 30 days worth of trading data of ~30GB size, I break it into a file per day of ~1GB size. I subsequently process each file separately and aggregate results at the end
One of the biggest advantages is that it allows parallel processing of the files (either multiple threads or processes)
The other advantage is that file manipulation (like adding/removing dates in the example) can be accomplished by regular shell commands, which is not be possible in more advanced/complicated file formats
This approach doesn't cover all scenarios, but is very useful in a lot of them
I got your problem , and here is my answer:
prices = [5, 12, 45]
list=['1','2','3']
for i in range(1,3):
vars()["prices"+list[0]]=prices[0]
print ("prices[i]=" +prices[i])
so while printing:
price1 = 5
price2 = 12
price3 = 45
If you want a native bash
solution
for file in /home/user/*; do
echo "${file##*/}"
done
The above uses Parameter Expansion which is native to the shell and does not require a call to an external binary such as basename
However, might I suggest just using find
find /home/user -type f -printf "%f\n"
sed '/^cdef$/r'<(
echo "line1"
echo "line2"
echo "line3"
echo "line4"
) -i -- input.txt
In Bootstrap 4, you can add mx-auto
class to your img
tag.
For instance, if your image has a width of 75%, it should look like this:
<img class="d-block w-75 mx-auto" src="image.jpg" alt="First slide">
Bootstrap will automatically translate mx-auto
to:
ml-auto, .mx-auto {
margin-left: auto !important;
}
.mr-auto, .mx-auto {
margin-right: auto !important;
}
Matplotlib uses a dictionary from its colors.py module.
To print the names use:
# python2:
import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
print(name, hex)
# python3:
import matplotlib
for name, hex in matplotlib.colors.cnames.items():
print(name, hex)
This is the complete dictionary:

You could plot them like this:
import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math
fig = plt.figure()
ax = fig.add_subplot(111)
ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count
for c in colors.cnames:
pos = (x / x_count, y / y_count)
ax.add_patch(patches.Rectangle(pos, w, h, color=c))
ax.annotate(c, xy=pos)
if y >= y_count-1:
x += 1
y = 0
else:
y += 1
plt.show()
Your class needs to extend from ActionBarActivity
, rather than a plain Activity
in order to use the getSupport*()
methods.
Update [2015/04/23]: With the release of Android Support Library 22.1, you should now extend AppCompatActivity.
Also, you no longer have to extend ActionBarActivity
or AppCompatActivity
, as you can now incorporate an AppCompatDelegate
instance in any activity.
You said Linux, so you luck out (at least it should be available, not sure when it was added):
diff --brief --recursive dir1/ dir2/ # GNU long options
diff -qr dir1/ dir2/ # common short options
Should do what you need.
If you also want to see differences for files that may not exist in either directory:
diff --brief --recursive --new-file dir1/ dir2/ # GNU long options
diff -qrN dir1/ dir2/ # common short options
Just use for True:
<li ng-if="area"></li>
and for False:
<li ng-if="area === false"></li>
The accepted answer works well. Just for completeness (and since I like it's shortness), I wanted to share how to to it with compass (SCSS/SASS):
body{
$colorStart: rgba(0,0,0,0);
$colorEnd: rgba(0,0,0,0.8);
@include background-image(linear-gradient(to bottom, $colorStart, $colorEnd), url("bg.jpg"));
}
A wildcard *
can be translated as .*
or .*?
regex pattern.
You might need to use a singleline mode to match newline symbols, and in this case, you can use (?s)
as part of the regex pattern.
You can set it for the whole or part of the pattern:
X* = > @"X(?s:.*)"
*X = > @"(?s:.*)X"
*X* = > @"(?s).*X.*"
*X*YZ* = > @"(?s).*X.*YZ.*"
X*YZ*P = > @"(?s:X.*YZ.*P)"
In case you are coming into this right now, I've just been through it today and can summarize where this stands. If you did not try this yet, some details here might help.
I think @Omid Ariyan's approach is the best way. Add the pre-commit and post-checkout scripts. DON'T forget to name them exactly the way Omid does and DON'T forget to make them executable. If you forget either of those, they have no effect and you run "git commit" over and over wondering why nothing happens :) Also, if you cut and paste out of the web browser, be careful that the quotation marks and ticks are not altered.
If you run the pre-commit script once (by running a git commit), then the file .permissions will be created. You can add it to the repository and I think it is unnecessary to add it over and over at the end of the pre-commit script. But it does not hurt, I think (hope).
There are a few little issues about the directory name and the existence of spaces in the file names in Omid's scripts. The spaces were a problem here and I had some trouble with the IFS fix. For the record, this pre-commit script did work correctly for me:
#!/bin/bash
SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions
# Clear the permissions database file
> $DATABASE
echo -n "Backing-up file permissions..."
IFSold=$IFS
IFS=$'\n'
for FILE in `git ls-files`
do
# Save the permissions of all the files in the index
echo $FILE";"`stat -c "%a;%U;%G" $FILE` >> $DATABASE
done
IFS=${IFSold}
# Add the permissions database file to the index
git add $DATABASE
echo "OK"
Now, what do we get out of this?
The .permissions file is in the top level of the git repo. It has one line per file, here is the top of my example:
$ cat .permissions
.gitignore;660;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.doc;664;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.pdf;664;pauljohn;pauljohn
As you can see, we have
filepath;perms;owner;group
In the comments about this approach, one of the posters complains that it only works with same username, and that is technically true, but it is very easy to fix it. Note the post-checkout script has 2 action pieces,
# Set the file permissions
chmod $PERMISSIONS $FILE
# Set the file owner and groups
chown $USER:$GROUP $FILE
So I am only keeping the first one, that's all I need. My user name on the Web server is indeed different, but more importantly you can't run chown unless you are root. Can run "chgrp", however. It is plain enough how to put that to use.
In the first answer in this post, the one that is most widely accepted, the suggestion is so use git-cache-meta, a script that is doing the same work that the pre/post hook scripts here are doing (parsing output from git ls-files
). These scripts are easier for me to understand, the git-cache-meta code is rather more elaborate. It is possible to keep git-cache-meta in the path and write pre-commit and post-checkout scripts that would use it.
Spaces in file names are a problem with both of Omid's scripts. In the post-checkout script, you'll know you have the spaces in file names if you see errors like this
$ git checkout -- upload.sh
Restoring file permissions...chmod: cannot access '04.StartingValuesInLISREL/Open': No such file or directory
chmod: cannot access 'Notebook.onetoc2': No such file or directory
chown: cannot access '04.StartingValuesInLISREL/Open': No such file or directory
chown: cannot access 'Notebook.onetoc2': No such file or directory
I'm checking on solutions for that. Here's something that seems to work, but I've only tested in one case
#!/bin/bash
SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions
echo -n "Restoring file permissions..."
IFSold=${IFS}
IFS=$
while read -r LINE || [[ -n "$LINE" ]];
do
FILE=`echo $LINE | cut -d ";" -f 1`
PERMISSIONS=`echo $LINE | cut -d ";" -f 2`
USER=`echo $LINE | cut -d ";" -f 3`
GROUP=`echo $LINE | cut -d ";" -f 4`
# Set the file permissions
chmod $PERMISSIONS $FILE
# Set the file owner and groups
chown $USER:$GROUP $FILE
done < $DATABASE
IFS=${IFSold}
echo "OK"
exit 0
Since the permissions information is one line at a time, I set IFS to $, so only line breaks are seen as new things.
I read that it is VERY IMPORTANT to set the IFS environment variable back the way it was! You can see why a shell session might go badly if you leave $ as the only separator.
jqPlot looks pretty good and it is open source.
Here's a link to the most impressive and up-to-date jqPlot examples.
You could add dataformatstring="{0:M-dd-yyyy}
" attribute to the bound field, like this:
<asp:BoundField DataField="Date" HeaderText="Date" DataFormatString="{0:dd-M-yyyy}" />
Applies to Bootstrap 3 only.
Ignoring the letters (xs, sm, md, lg) for now, I'll start with just the numbers...
col-*-6
spans 6 of 12 columns (half the width), col-*-12
spans 12 of 12 columns (the entire width), etcSo, if you want two equal columns to span a div, write
<div class="col-xs-6">Column 1</div>
<div class="col-xs-6">Column 2</div>
Or, if you want three unequal columns to span that same width, you could write:
<div class="col-xs-2">Column 1</div>
<div class="col-xs-6">Column 2</div>
<div class="col-xs-4">Column 3</div>
You'll notice the # of columns always add up to 12. It can be less than twelve, but beware if more than 12, as your offending divs will bump down to the next row (not .row
, which is another story altogether).
You can also nest columns within columns, (best with a .row
wrapper around them) such as:
<div class="col-xs-6">
<div class="row">
<div class="col-xs-4">Column 1-a</div>
<div class="col-xs-8">Column 1-b</div>
</div>
</div>
<div class="col-xs-6">
<div class="row">
<div class="col-xs-2">Column 2-a</div>
<div class="col-xs-10">Column 2-b</div>
</div>
</div>
Each set of nested divs also span up to 12 columns of their parent div. NOTE: Since each .col
class has 15px padding on either side, you should usually wrap nested columns in a .row
, which has -15px margins. This avoids duplicating the padding and keeps the content lined up between nested and non-nested col classes.
-- You didn't specifically ask about the xs, sm, md, lg
usage, but they go hand-in-hand so I can't help but touch on it...
In short, they are used to define at which screen size that class should apply:
Read the "Grid Options" chapter from the official Bootstrap documentation for more details.
You should usually classify a div using multiple column classes so it behaves differently depending on the screen size (this is the heart of what makes bootstrap responsive). eg: a div with classes col-xs-6
and col-sm-4
will span half the screen on the mobile phone (xs) and 1/3 of the screen on tablets(sm).
<div class="col-xs-6 col-sm-4">Column 1</div> <!-- 1/2 width on mobile, 1/3 screen on tablet) -->
<div class="col-xs-6 col-sm-8">Column 2</div> <!-- 1/2 width on mobile, 2/3 width on tablet -->
NOTE: as per comment below, grid classes for a given screen size apply to that screen size and larger unless another declaration overrides it (i.e. col-xs-6 col-md-4
spans 6 columns on xs
and sm
, and 4 columns on md
and lg
, even though sm
and lg
were never explicitly declared)
NOTE: if you don't define xs
, it will default to col-xs-12
(i.e. col-sm-6
is half the width on sm
, md
and lg
screens, but full-width on xs
screens).
NOTE: it's actually totally fine if your .row
includes more than 12 cols, as long as you are aware of how they will react. --This is a contentious issue, and not everyone agrees.
Any time you need to separate allocation from initialization, you'll need placement new and explicit calling of the destructor manually. Today, it's rarely necessary, since we have the standard containers, but if you have to implement some new sort of container, you'll need it.
In addition to gmaggio's answer if you need to dynamically REPLACE
and UPDATE
according to another column you can do for example:
UPDATE your_table t1
INNER JOIN other_table t2
ON t1.field_id = t2.field_id
SET t1.your_field = IF(LOCATE('articles/updates/', t1.your_field) > 0,
REPLACE(t1.your_field, 'articles/updates/', t2.new_folder), t1.your_field)
WHERE...
In my example the string articles/news/
is stored in other_table t2
and there is no need to use LIKE
in the WHERE
clause.
I have found that this is sometimes caused by running a MS Dos version of a file. If that's the case dos2ux should fix that.
dos2ux file1 > file2
Take a look at http://www.tingodb.com. I believe it does what you looking for. Additionally it fully compatible with MongoDB API. This reduces implementation risks and gives you option to switch to heavy solution as your app grows.
This got bumped to the top because of an edit ... The answers have gotten a bit stale, and not as useful today as another solution has been added to the standard.
There is now an "all" shorthand property.
#elementId select.funTimes {
all: initial;
}
This sets all css properties to their initial value ... note some of the initial values are inherit; Resulting in some formatting still taking place on the element.
Because of that pause required when reading the code or reviewing it in the future, don't use it unless you most as the review process is a point where errors/bugs can be made! when editing the page. But clearly if there are a large number of properties that need to be reset, then "all" is the way to go.
Standard is online here: https://drafts.csswg.org/css-cascade/#all-shorthand
In json strict mode, you'll have to keep the order:
{
"dt": {
"$gte": {
"$date": "2013-10-01T00:00:00.000Z"
}
}
}
Only thing which worked to define my search queries on mlab.com.
The command on OSX should be exactly the same as it is Unix under the pretty UI.
jQuery provides an each()
method, not forEach()
. You can break out of each
by returning false
. forEach()
is part of the ECMA-262 standard, and the only way to break out of that that I'm aware of is by throwing an exception.
function recurs(comment) {
try {
comment.comments.forEach(function(elem) {
recurs(elem);
if (...) throw "done";
});
} catch (e) { if (e != "done") throw e; }
}
Ugly, but does the job.

Use position:fixed
on the video, set it to 100% width/height, and put a negative z-index
on it so it appears behind everything.
If you look at VideoJS, the controls are just html elements sitting on top of the video, using z-index to make sure they're above.
HTML
<video id="video_background" src="video.mp4" autoplay>
(Add webm and ogg sources to support more browsers)
CSS
#video_background {
position: fixed;
top: 0;
left: 0;
bottom: 0;
right: 0;
z-index: -1000;
}
It'll work in most HTML5 browsers, but probably not iPhone/iPad, where the video needs to be activated, and doesn't like elements over it.
Looks like the Google USB drivers have been updated to support Glass out of the box, so as long as you use the latest drivers, you should be able to access Glass via ADB. In my particular situation, I had connected Glass to my machine sometime mid-2014 but did nothing with it. Now when I was trying to connect it, I would not see it show up in ADB despite showing up in Device Manager. After much trial and error, I found out that I had to:
I was then able to reinstall the driver via regular Windows update. This forced it to look for the newest driver. Not sure why it was not getting updated before, but I hope this will help someone out there still struggling with this.
The function fromJSON() in RJSONIO, rjson and jsonlite don't return a simple 2D data.frame for complex nested json objects.
To overcome this you can use tidyjson. It takes in a json and always returns a data.frame. It is currently not availble in CRAN, you can get it here: https://github.com/sailthru/tidyjson
Update: tidyjson is now available in cran, you can install it directly using install.packages("tidyjson")
Copied from the stacktrace:
BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()
By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib
has a constructor with a SessionFactory
argument. By adding the @Autowired
annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory
in your case, and provide it as a constructor argument, e.g.
@Autowired

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").
From the command line, you can type
python setup.py --help
...to get a list of commands. What you are looking to do is...
python setup.py install
You can specify a callback function:
$(selector).fadeOut('slow', function() {
// will be called when the element finishes fading out
// if selector matches multiple elements it will be called once for each
});
See the official documentation reference: https://docs.docker.com/engine/reference/builder/#expose
The EXPOSE
allow you to define private (container) and public (host) ports to expose at image build time for when the container is running if you run the container with -P
.
$ docker help run
...
-P, --publish-all Publish all exposed ports to random ports
...
The public port and protocol are optional, if not a public port is specified, a random port will be selected on host by docker to expose the specified container port on Dockerfile.
A good pratice is do not specify public port, because it limits only one container per host ( a second container will throw a port already in use ).
You can use -p
in docker run
to control what public port the exposed container ports will be connectable.
Anyway, If you do not use EXPOSE
(with -P
on docker run) nor -p
, no ports will be exposed.
If you always use -p
at docker run
you do not need EXPOSE
but if you use EXPOSE
your docker run
command may be more simple, EXPOSE
can be useful if you don't care what port will be expose on host, or if you are sure of only one container will be loaded.
It would appear as though this event has some clipboardData
property attached to it (it may be nested within the originalEvent
property). The clipboardData
contains an array of items and each one of those items has a getAsString()
function that you can call. This returns the string representation of what is in the item.
Those items also have a getAsFile()
function, as well as some others which are browser specific (e.g. in webkit browsers, there is a webkitGetAsEntry()
function).
For my purposes, I needed the string value of what is being pasted. So, I did something similar to this:
$(element).bind("paste", function (e) {
e.originalEvent.clipboardData.items[0].getAsString(function (pStringRepresentation) {
debugger;
// pStringRepresentation now contains the string representation of what was pasted.
// This does not include HTML or any markup. Essentially jQuery's $(element).text()
// function result.
});
});
You'll want to perform an iteration through the items, keeping a string concatenation result.
The fact that there is an array of items makes me think more work will need to be done, analyzing each item. You'll also want to do some null/value checks.
Change the content type to ms-excel in the html and browser shall open the html in the Excel as xls. If you want control over the transformation of HTML to excel use POI libraries to do so.

To use image in Flutter. Do these steps.
1. Create a Directory inside assets folder named images. As shown in figure below
2. Put your desired images to images folder.
3. Open pubpsec.yaml file . And add declare your images.Like:--
4. Use this images in your code as.
Card(

Talking about java Ide it is better to go for NetBeans.In My opinion it is better and provide great advantage over other ide but it has disadvantage over Eclipse that it grabs more more while working but do to its features and support i suggest Netbeans than any ide
I created a folder named a in /home/prasanth and copied your code to a file named A.java. I compiled from /home/prasanth as javac a/A.java

The following code worked for me:-
.nav-pills .nav-link.active, .nav-pills .show>.nav-link {

}
Note:- This worked for me using Bootstrap 4
$.ajax(), $.get(), $.post(), $.load()
functions of jQuery internally send XML HTTP
request.
among these the load()
is only dedicated for a particular DOM Element
. See jQuery Ajax Doc. A details Q.A. on these are Here .
You can use font face like this:
@font-face {
font-family:"Name-Of-Font";
src: url("yourfont.ttf") format("truetype");
}
From the documentation:
list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, soa.insert(0, x)
inserts at the front of the list, anda.insert(len(a),x)
is equivalent toa.append(x)
http://docs.python.org/2/tutorial/datastructures.html#more-on-lists
A little intro to dictionary
d={'a':'apple','b':'ball'}
d.keys() # displays all keys in list
['a','b']
d.values() # displays your values in list
['apple','ball']
d.items() # displays your pair tuple of key and value
[('a','apple'),('b','ball')
Print keys,values method one
for x in d.keys():
print x +" => " + d[x]
Another method
for key,value in d.items():
print key + " => " + value
You can get keys using iter
>>> list(iter(d))
['a', 'b']
You can get value of key of dictionary using get(key, [value])
:
d.get('a')
'apple'
If key is not present in dictionary,when default value given, will return value.
d.get('c', 'Cat')
'Cat'
A simple function to return a JSON response with the HTTP status code.
function json_response($data=null, $httpStatus=200)
{
header_remove();
header("Content-Type: application/json");
http_response_code($httpStatus);
echo json_encode($data);
exit();
}
Use an infinite loop:
while True:
print('Hello world!')
This certainly can apply to your start()
function as well; you can exit the loop with either break
, or use return
to exit the function altogether, which also terminates the loop:
def start():
print ("Welcome to the converter toolkit made by Alan.")
while True:
op = input ("Please input what operation you wish to perform. 1 for Fahrenheit to Celsius, 2 for meters to centimetres and 3 for megabytes to gigabytes")
if op == "1":
f1 = input ("Please enter your fahrenheit temperature: ")
f1 = int(f1)
a1 = (f1 - 32) / 1.8
a1 = str(a1)
print (a1+" celsius")
elif op == "2":
m1 = input ("Please input your the amount of meters you wish to convert: ")
m1 = int(m1)
m2 = (m1 * 100)
m2 = str(m2)
print (m2+" m")
if op == "3":
mb1 = input ("Please input the amount of megabytes you want to convert")
mb1 = int(mb1)
mb2 = (mb1 / 1024)
mb3 = (mb2 / 1024)
mb3 = str(mb3)
print (mb3+" GB")
else:
print ("Sorry, that was an invalid command!")
If you were to add an option to quit as well, that could be:
if op.lower() in {'q', 'quit', 'e', 'exit'}:
print("Goodbye!")
return
for example.

Select your database and ready to go.
Probably the "best" way to do this (quoted since "best" is a subjective term) is to keep a running (non-integral) tally of where you are, and round that value.
Then use that along with the history to work out what value should be used. For example, using the values you gave:
Value CumulValue CumulRounded PrevBaseline Need
--------- ---------- ------------ ------------ ----
0
13.626332 13.626332 14 0 14 ( 14 - 0)
47.989636 61.615968 62 14 48 ( 62 - 14)
9.596008 71.211976 71 62 9 ( 71 - 62)
28.788024 100.000000 100 71 29 (100 - 71)
---
100
At each stage, you don't round the number itself. Instead, you round the accumulated value and work out the best integer that reaches that value from the previous baseline - that baseline is the cumulative value (rounded) of the previous row.
This works because you're not losing information at each stage but rather using the information more intelligently. The 'correct' rounded values are in the final column and you can see that they sum to 100.
You can see the difference between this and blindly rounding each value, in the third value above. While 9.596008
would normally round up to 10
, the accumulated 71.211976
correctly rounds down to 71
- this means that only 9
is needed to add to the previous baseline of 62
.
This also works for "problematic" sequence like three roughly-1/3
values, where one of them should be rounded up:
Value CumulValue CumulRounded PrevBaseline Need
--------- ---------- ------------ ------------ ----
0
33.333333 33.333333 33 0 33 ( 33 - 0)
33.333333 66.666666 67 33 34 ( 67 - 33)
33.333333 99.999999 100 67 33 (100 - 67)
---
100
@Tim's answer only does half the work -- that gets it into a datetime.datetime object.
To get it into the string format you require, you use datetime.strftime:
print(datetime.strftime('%b %d,%Y'))
I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.
Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty()
.
Looking at your code what you need to do is add the functionality to close the window and update the page. In your "Yes" function you should write:
buttons: {
"Ja": function() {
$.post(a.href);
$(a). // code to remove the table row
$("#dialog").dialog("close");
},
"Nej": function() { $(this).dialog("close"); }
},
The code to remove the table row isn't fun to write so I'll let you deal with the nitty gritty details, but basically, you need to tell the dialog what to do after you post it. It may be a smart dialog but it needs some kind of direction.
In the HTML source provided, the element #tfl
has an inline style "display:block
". Inline style will always override stylesheets styles…
Then, you have some options (while as you said you can't modify the html code nor using javascript):
display:none
with !important
rule (not recommended)put the div offscreen with theses rules :
#tfl {
position: absolute;
left: -9999px;
}
There is obviously another process listening on the port. You might find out that process by using the following command:
$ lsof -i :8000
or change your tornado app's port. tornado's error info not Explicitly on this.
In theory, inverting if
could lead to better performance if it increases branch prediction hit rate. In practice, I think it is very hard to know exactly how branch prediction will behave, especially after compiling, so I would not do it in my day-to-day development, except if I am writing assembly code.
More on branch prediction here.
ID's must be unique (only be given to one element in the DOM at a time), whereas classes don't have to be. You've already discovered the CSS .
class and #
ID prefixes, so that's pretty much it.
It looks like you're building DOM elements from strings. You just need to add some quotes around result.name:
'<input type="button" onClick="gotoNode(\'' + result.name + '\')" />'
You should really be doing this with proper DOM methods though.
var inputElement = document.createElement('input');
inputElement.type = "button"
inputElement.addEventListener('click', function(){
gotoNode(result.name);
});
?document.body.appendChild(inputElement);?
Just be aware that if this is a loop or something, result
will change before the event fires and you'd need to create an additional scope bubble to shadow the changing variable.
There is another solution, if you have binary logs active on your server you can use mysqlbinlog
generate a sql file with it
mysqlbinlog binary_log_file > query_log.sql
then search for your missing rows. If you don't have it active, no other solution. Make backups next time.
This page provides great understanding about the constructor
and destructor
attribute implementation and the sections within within ELF that allow them to work. After digesting the information provided here, I compiled a bit of additional information and (borrowing the section example from Michael Ambrus above) created an example to illustrate the concepts and help my learning. Those results are provided below along with the example source.
As explained in this thread, the constructor
and destructor
attributes create entries in the .ctors
and .dtors
section of the object file. You can place references to functions in either section in one of three ways. (1) using either the section
attribute; (2) constructor
and destructor
attributes or (3) with an inline-assembly call (as referenced the link in Ambrus' answer).
The use of constructor
and destructor
attributes allow you to additionally assign a priority to the constructor/destructor to control its order of execution before main()
is called or after it returns. The lower the priority value given, the higher the execution priority (lower priorities execute before higher priorities before main() -- and subsequent to higher priorities after main() ). The priority values you give must be greater than100
as the compiler reserves priority values between 0-100 for implementation. Aconstructor
or destructor
specified with priority executes before a constructor
or destructor
specified without priority.
With the 'section' attribute or with inline-assembly, you can also place function references in the .init
and .fini
ELF code section that will execute before any constructor and after any destructor, respectively. Any functions called by the function reference placed in the .init
section, will execute before the function reference itself (as usual).
I have tried to illustrate each of those in the example below:
#include <stdio.h>
#include <stdlib.h>
/* test function utilizing attribute 'section' ".ctors"/".dtors"
to create constuctors/destructors without assigned priority.
(provided by Michael Ambrus in earlier answer)
*/
#define SECTION( S ) __attribute__ ((section ( S )))
void test (void) {
printf("\n\ttest() utilizing -- (.section .ctors/.dtors) w/o priority\n");
}
void (*funcptr1)(void) SECTION(".ctors") =test;
void (*funcptr2)(void) SECTION(".ctors") =test;
void (*funcptr3)(void) SECTION(".dtors") =test;
/* functions constructX, destructX use attributes 'constructor' and
'destructor' to create prioritized entries in the .ctors, .dtors
ELF sections, respectively.
NOTE: priorities 0-100 are reserved
*/
void construct1 () __attribute__ ((constructor (101)));
void construct2 () __attribute__ ((constructor (102)));
void destruct1 () __attribute__ ((destructor (101)));
void destruct2 () __attribute__ ((destructor (102)));
/* init_some_function() - called by elf_init()
*/
int init_some_function () {
printf ("\n init_some_function() called by elf_init()\n");
return 1;
}
/* elf_init uses inline-assembly to place itself in the ELF .init section.
*/
int elf_init (void)
{
__asm__ (".section .init \n call elf_init \n .section .text\n");
if(!init_some_function ())
{
exit (1);
}
printf ("\n elf_init() -- (.section .init)\n");
return 1;
}
/*
function definitions for constructX and destructX
*/
void construct1 () {
printf ("\n construct1() constructor -- (.section .ctors) priority 101\n");
}
void construct2 () {
printf ("\n construct2() constructor -- (.section .ctors) priority 102\n");
}
void destruct1 () {
printf ("\n destruct1() destructor -- (.section .dtors) priority 101\n\n");
}
void destruct2 () {
printf ("\n destruct2() destructor -- (.section .dtors) priority 102\n");
}
/* main makes no function call to any of the functions declared above
*/
int
main (int argc, char *argv[]) {
printf ("\n\t [ main body of program ]\n");
return 0;
}
output:
init_some_function() called by elf_init()
elf_init() -- (.section .init)
construct1() constructor -- (.section .ctors) priority 101
construct2() constructor -- (.section .ctors) priority 102
test() utilizing -- (.section .ctors/.dtors) w/o priority
test() utilizing -- (.section .ctors/.dtors) w/o priority
[ main body of program ]
test() utilizing -- (.section .ctors/.dtors) w/o priority
destruct2() destructor -- (.section .dtors) priority 102
destruct1() destructor -- (.section .dtors) priority 101
The example helped cement the constructor/destructor behavior, hopefully it will be useful to others as well.
I also get the same error in an ASP.NET application when I saved some unicode data (Hindi) in the Web.config file and saved it with "Unicode" encoding.
It fixed the error for me when I saved the Web.config file with "UTF-8" encoding.
Perhaps a more realistic example about not sorting a Map object but preparing the sorting up front before doing the Map. The syntax gets actually pretty compact if you do it like this. You can apply the sorting before the map function like this, with a sort function before map (Example from a React app I am working on using JSX syntax)
Mark that I here define a sorting function inside using an arrow function that returns -1 if it is smaller and 0 otherwise sorted on a property of the Javascript objects in the array I get from an API.
report.ProcedureCodes.sort((a, b) => a.NumericalOrder < b.NumericalOrder ? -1 : 0).map((item, i) =>
<TableRow key={i}>
<TableCell>{item.Code}</TableCell>
<TableCell>{item.Text}</TableCell>
{/* <TableCell>{item.NumericalOrder}</TableCell> */}
</TableRow>
)
You can declare columns/variables as varchar2(n CHAR) and varchar2(n byte).
n CHAR means the variable will hold n characters. In multi byte character sets you don't always know how many bytes you want to store, but you do want to garantee the storage of a certain amount of characters.
n bytes means simply the number of bytes you want to store.
varchar is deprecated. Do not use it. What is the difference between varchar and varchar2?
Starting on Psych 3.0 you can add the symbolize_names: option
Psych.load("---\n foo: bar")
# => {"foo"=>"bar"}
Psych.load("---\n foo: bar", symbolize_names: true)
# => {:foo=>"bar"}
Note: if you have a lower Psych version than 3.0 symbolize_names:
will be silently ignored.

It is just a hint for the Service Provider on what to expect from the NameID returned by the Identity Provider. It can be:
unspecified
emailAddress
– e.g. [email protected]
X509SubjectName
– e.g. CN=john,O=Company Ltd.,C=US
WindowsDomainQualifiedName
– e.g. CompanyDomain\John
kerberos
– e.g. john@realm
entity
– this one in used to identify entities that provide SAML-based services and looks like a URIpersistent
– this is an opaque service-specific identifier which must include a pseudo-random value and must not be traceable to the actual user, so this is a privacy feature.transient
– opaque identifier which should be treated as temporary.In Intellij 13, it looks it's slightly different again. Here are the instructions for Intellij 13:
Classes
(even if it's properties), press OK and OK againIn general, if you have your coins COIN[] and your "change range" 1..MAX, the following should find the maximum number of coins.
Initialise array CHANGEVAL[MAX] to -1
For each element coin in COIN:
set CHANGEVAL[coin] to 1
Until there are no more -1 in CHANGEVAL:
For each index I over CHANGEVAL:
if CHANGEVAL[I] != -1:
let coincount = CHANGEVAL[I]
For each element coin in COIN:
let sum = coin + I
if (COINS[sum]=-1) OR ((coincount+1)<COINS[sum]):
COINS[sum]=coincount+1
I don't know if the check for coin-minimality in the inner conditional is, strictly speaking, necessary. I would think that the minimal chain of coin-additions would end up being correct, but better safe than sorry.
jQuery.fn
is defined shorthand for jQuery.prototype
. From the source code:
jQuery.fn = jQuery.prototype = {
// ...
}
That means jQuery.fn.jquery
is an alias for jQuery.prototype.jquery
, which returns the current jQuery version. Again from the source code:
// The current version of jQuery being used
jquery: "@VERSION",
To split a string with a delimiter with GNU sed you say:
sed 's/delimiter/\n/g' # GNU sed
For example, to split using :
as a delimiter:
$ sed 's/:/\n/g' <<< "he:llo:you"
he
llo
you
Or with a non-GNU sed:
$ sed $'s/:/\\\n/g' <<< "he:llo:you"
he
llo
you
In this particular case, you missed the g
after the substitution. Hence, it is just done once. See:
$ echo "string1:string2:string3:string4:string5" | sed s/:/\\n/g
string1
string2
string3
string4
string5
g
stands for g
lobal and means that the substitution has to be done globally, that is, for any occurrence. See that the default is 1 and if you put for example 2, it is done 2 times, etc.
All together, in your case you would need to use:
sed 's/:/\\n/g' ~/Desktop/myfile.txt
Note that you can directly use the sed ... file
syntax, instead of unnecessary piping: cat file | sed
.

I'm still going suggest the 2 map solution, but with a tweest
Map<K2, K1> m2;
Map<K1, V> m1;
This scheme lets you have an arbitrary number of key "aliases".
It also lets you update the value through any key without the maps getting out of sync.
You could add in your code a call system with the new definition:
sprintf(newdef,"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:%s:%s",ld1,ld2);
system(newdef);
But, I don't know it that is the rigth solution but it works.

The shared pointer manages both the object itself, and a small object containing the reference count and other housekeeping data. make_shared
can allocate a single block of memory to hold both of these; constructing a shared pointer from a pointer to an already-allocated object will need to allocate a second block to store the reference count.
As well as this efficiency, using make_shared
means that you don't need to deal with new
and raw pointers at all, giving better exception safety - there is no possibility of throwing an exception after allocating the object but before assigning it to the smart pointer.
Just a simplification of the Tim's answer. The groovy way to do it is using a map, as already suggested, but then let's put the mandatory parameters also in the map. This will look like this:
def someMethod(def args) {
println "MANDATORY1=${args.mandatory1}"
println "MANDATORY2=${args.mandatory2}"
println "OPTIONAL1=${args?.optional1}"
println "OPTIONAL2=${args?.optional2}"
}
someMethod mandatory1:1, mandatory2:2, optional1:3
with the output:
MANDATORY1=1
MANDATORY2=2
OPTIONAL1=3
OPTIONAL2=null
This looks nicer and the advantage of this is that you can change the order of the parameters as you like.
Overloading is the concept in which you have same signatures or methods with same name but different parameters and overriding, we have same name methods with different parameters also have inheritance is known as overriding.

The github project JavaScript-Load-Image provides a complete solution to the EXIF orientation problem, correctly rotating/mirroring images for all 8 exif orientations. See the online demo of javascript exif orientation
The image is drawn onto an HTML5 canvas. Its correct rendering is implemented in js/load-image-orientation.js through canvas operations.
Hope this saves somebody else some time, and teaches the search engines about this open source gem :)
This is going to be largely dependent on the RDBMS you're using, and whether a .NET option even exists for that RDBMS.
If you're using SQL Server, use the SqlBulkCopy class.
For other database vendors, try googling for them specifically. For example a search for ".NET Bulk insert into Oracle" turned up some interesting results, including this link back to Stack Overflow: Bulk Insert to Oracle using .NET.
Here is what I discovery since my Mac OS doesn't use all the easy answers. I used the jot command to generate a number since the $RANDOM variable solutions seems not to be very random in my test. When testing my solution I had a wide variance in the solutions provided in the output.
RANDOM1=`jot -r 1 1 235886`
#range of jot ( 1 235886 ) found from earlier wc -w /usr/share/dict/web2
echo $RANDOM1
head -n $RANDOM1 /usr/share/dict/web2 | tail -n 1
The echo of the variable is to get a visual of the generated random number.

IE=edge
means IE should use the latest (edge) version of its rendering enginechrome=1

As noticed by Lynda (see comments), the Compatibility changes in IE11 recommends Edge mode:
Starting with IE11, edge mode is the preferred document mode; it represents the highest support for modern standards available to the browser.
But the position of Microsoft was not clear. Another MSDN page did not recommend Edge mode:
Because Edge mode forces all pages to be opened in standards mode, regardless of the version of Internet Explorer, you might be tempted to use this for all pages viewed with Internet Explorer. Don't do this, as the
X-UA-Compatible
header is only supported starting with Windows Internet Explorer 8.
Instead, Microsoft recommended using <!DOCTYPE html>
:
If you want all supported versions of Internet Explorer to open your pages in standards mode, use the HTML5 document type declaration [...]
As Ricardo explains (in the comments below) any DOCTYPE (HTML4, XHTML1...) can be used to trigger Standards Mode, not only HTML5's DOCTYPE. The important thing is to always have a DOCTYPE in the page.
Clara Onager has even noticed in an older version of Specifying legacy document modes:
Edge mode is intended for testing purposes only; do not use it in a production environment.
It is so confusing that Usman Y thought Clara Onager was speaking about:
The [...] example is provided for illustrative purposes only; don't use it in a production environment.
<meta http-equiv="X-UA-Compatible" content="IE=7,9,10" >
Well... In the rest of this answer I give more explanations why using content="IE=edge,chrome=1"
is a good practice in production.
For many years (2000 to 2008), IE market share was more than 80%. And IE v6 was considered as a de facto standard (80% to 97% market share in 2003, 2004, 2005 and 2006 for IE6 only, more market share with all IE versions).
As IE6 was not respecting Web standards, developers had to test their website using IE6. That situation was great for Microsoft (MS) as web developers had to buy MS products (e.g. IE cannot be used without buying Windows), and it was more profit-making to stay non-compliant (i.e. Microsoft wanted to become the standard excluding other companies).
Therefore many many sites were IE6 compliant only, and as IE was not compliant with web standard, all these web sites was not well rendered on standards compliant browsers. Even worse, many sites required only IE.
However, at this time, Mozilla started Firefox development respecting as much as possible all the web standards (other browser were implemented to render pages as done by IE6). As more and more web developers wanted to use the new web standards features, more and more websites were more supported by Firefox than IE.
When IE market sharing was decreasing, MS realized staying standard incompatible was not a good idea. Therefore MS started to release new IE version (IE8/IE9/IE10) respecting more and more the web standards.
But the issue is all the websites designed for IE6: Microsoft could not release new IE versions incompatible with these old IE6-designed websites. Instead of deducing the IE version a website has been designed, MS requested developers to add extra data (X-UA-Compatible
) in their pages.
Nowadays, IE6 is still used (0.7% in 2016) (4.5% in January 2014), and some internet websites are still IE6-only-compliant. Some intranet website/applications are tested using IE6. Some intranet website are 100% functional only on IE6. These companies/departments prefer to postpone the migration cost: other priorities, nobody no longer knows how the website/application has been implemented, the owner of the legacy website/application went bankrupt...
China represents 50% of IE6 usage in 2013, but it may change in the next years as Chinese Linux distribution is being broadcast.
If you (try to) respect web standard, you can simply always use http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"
. To keep compatibility with old browsers, just avoid using latest web features: use the subset supported by the oldest browser you want to support. Or If you want to go further, you may adopt concepts as Graceful degradation, Progressive enhancement and Unobtrusive JavaScript. (You may also be pleased to read What should a web developer consider?.)
Do do not care about the best IE version rendering: this is not your job as browsers have to be compliant with web standards. If your site is standard compliant and use moderately latest features, therefore browsers have to be compliant with your website.
Moreover, as there are many campaigns to kill IE6 (IE6 no more, MS campaign), nowadays you may avoid wasting time with IE testing!
In 2009-2012, I worked for a company using IE6 as the official single browser allowed. I had to implement an intranet website for IE6 only. I decided to respect web standard but using the IE6-capable subset (HTML/CSS/JS).
It was hard, but when the company switched to IE8, the website was still well rendered because I had used Firefox and firebug to check the web-standard compatibility ;)
Our issue was simply the port number on the endpoint was incorrectly set to 8080. Changed it to 8443 and it worked.

The name
property is marked as protected
. This was added in TypeScript 1.3 and is now firmly established.
The makeSound
method is marked as abstract
, as is the class. You cannot directly instantiate an Animal
now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.
abstract class Animal {
constructor(protected name: string) { }
abstract makeSound(input : string) : string;
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name: string) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:
class Animal {
constructor(public name) { }
makeSound(input : string) : string {
throw new Error('This method is abstract');
}
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
Some people seem to turn autoescape off which carries security risks to manipulate the string display.
If you only want to insert some linebreaks into a string and convert the linebreaks into <br />
, then you could take a jinja macro like:
{% macro linebreaks_for_string( the_string ) -%}
{% if the_string %}
{% for line in the_string.split('\n') %}
<br />
{{ line }}
{% endfor %}
{% else %}
{{ the_string }}
{% endif %}
{%- endmacro %}
and in your template just call this with
{{ linebreaks_for_string( my_string_in_a_variable ) }}
Uninstall then run the setup program again but this time as Administrator. Make sure the VB bridge driver is selected during installation.
for me this works

Just noting that I've just changed my config.xml to look like Sebastian's example.
Something that's also helpful in debugging all this especially if you don't do local builds... is to download the XAP/IPA/APK files as built from PhoneGap cloud and create folders for each. Rename each file with a .ZIP extension and extract the contents of each to their respective folders. So basically, you can now see what's in the package that will be shipped to the phone.
Doing this, I can see that for the Microsoft Phone platform it's largely ignoring all my attempts at replacing the icon or splash screen. If you then replace the ApplicationIcon.png and SplashScreenImage.jpg, then re-zip the folderset and rename it again as a .XAP file you can then deploy it to your phone and it will work perfectly. Somehow, there's a way of just getting the PhoneGap build to turn your icon.png and icon.jpg into those two files. Perhaps Masood's suggestion is a possibility here and utilize a hook script.
Doing the same for the .IPA file (iOS) results in several files like icon-something.png at the parent level above www. They all appear to be blank.
Doing the same for the .APK file (Android) results in a res/drawable-something set of folders and it appears to have my icon.png in each one. It's the closest to a success I can claim at the moment.
This worked for me too. Later, I ended-up switching to the maven-antrun-plugin
to avoid warnings in Eclipse. And I prefer using default plugins when possible. Example:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>get-the-hostname</id>
<phase>package</phase>
<configuration>
<target>
<exec executable="bash">
<arg value="-c"/>
<arg value="hostname"/>
</exec>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>

You are missing the required <form>
element. Here is how your code should be like:
function IsEmpty() {
if (document.forms['frm'].question.value === "") {
alert("empty");
return false;
}
return true;
}
_x000D_
<form name="frm">
Question: <input name="question" /> <br />
<input id="insert" onclick="return IsEmpty();" type="submit" value="Add Question" />
</form>
_x000D_
Using sup on the letter "o" and a capital "C"
<sup>o</sup>C
_x000D_
Should work in all browsers and IE6+
So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.
protected void onCreate(Bundle savedInstanceState) { setContentView(R.layout.my_layout); Bitmap bitmap = getIntent().getParcelableExtra("image"); ImageView imageView = (ImageView) findViewById(R.id.imageview); imageView.setImageBitmap(bitmap); }

My solution, in case you have a TextView as each row of the spinner:
// TODO: add a fake item as the last one of "items"
final ArrayAdapter<String> adapter=new ArrayAdapter<String>(..,..,items)
{
@Override
public View getDropDownView(final int position,final View convertView,final ViewGroup parent)
{
final View dropDownView=super.getDropDownView(position,convertView,parent);
((TextView)dropDownView.findViewById(android.R.id.text1)).setHeight(position==getCount()-1?0:getDimensionFromAttribute(..,R.attr.dropdownListPreferredItemHeight));
dropDownView.getLayoutParams().height=position==getCount()-1?0:LayoutParams.MATCH_PARENT;
return dropDownView;
}
}
...
spinner.setAdapter(adapter);
_actionModeSpinnerView.setSelection(dataAdapter.getCount()-1,false);

return 0;
}

Be careful using the answer provide by @DevNG. Arrays.asList() returns internal implementation of ArrayList that doesn't implement some useful methods like add(), delete(), etc. If you call them an UnsupportedOperationException will be thrown. In order to get real ArrayList instance you need to write something like this:
List<Video> = new ArrayList<>(Arrays.asList(videoArray));
You could try something like this (copied from the jQuery Ajax examples)
var request = $.ajax({
url: "script.php",
type: "POST",
data: {id : menuId},
dataType: "html"
});
request.done(function(msg) {
console.log( msg );
});
request.fail(function(jqXHR, textStatus) {
console.log( "Request failed: " + textStatus );
});
The problem with your original code is that the error argument you pass into your on function isn't actually coming from anywhere. JQuery on doesn't return a second argument, and even if it did, it would relate to the click event not the Ajax call.
apply
takes a function to apply to each value, not the series, and accepts kwargs.
So, the values do not have the .size()
method.
Perhaps this would work:
from pandas import *
d = {"my_label": Series(['A','B','A','C','D','D','E'])}
df = DataFrame(d)
def as_perc(value, total):
return value/float(total)
def get_count(values):
return len(values)
grouped_count = df.groupby("my_label").my_label.agg(get_count)
data = grouped_count.apply(as_perc, total=df.my_label.count())
The .agg()
method here takes a function that is applied to all values of the groupby object.
I had a similar case for the default groovy compiler plugin
The solution was to install ME2 provided by Springsource according to this answer
Plugin execution not covered by lifecycle configuration maven error
This immediately solved the "Plugin execution not covered by lifecycle configuration" problem in Eclispe Juno.
I had the same problem and could not find a solution. Mark90 is right there are a lot info.plist files and you should edit the correct. Go to Project, under TARGETS select the project (not the tests), in the tab bar select Info and add the permission under "Custom iOS Target Properties".
Using a data attribute on an HTML element avoids having to use inline scripting, which in turn means you can use stricter CSP rules for increased security.
Specify a data attribute like so:
<div id="mydiv" data-geocode='{{ geocode|tojson }}'>...</div>
Then access it in a static JavaScript file like so:
// Raw JavaScript
var geocode = JSON.parse(document.getElementById("mydiv").dataset.geocode);
// jQuery
var geocode = JSON.parse($("#mydiv").data("geocode"));
These are automatic variables, like $null
, $true
, $false
etc.
about_Automatic_Variables
, see https://technet.microsoft.com/en-us/library/hh847768.aspx?f=255&MSPPError=-2147217396
$NULL
$null
is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.Windows PowerShell treats
$null
as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.For example, when
$null
is included in a collection, it is counted as one of the objects.C:\PS> $a = ".dir", $null, ".pdf" C:\PS> $a.count 3
If you pipe the
$null
variable to theForEach-Object
cmdlet, it generates a value for$null
, just as it does for the other objects.PS C:\ps-test> ".dir", $null, ".pdf" | Foreach {"Hello"} Hello Hello Hello
As a result, you cannot use
$null
to mean "no parameter value." A parameter value of$null
overrides the default parameter value.However, because Windows PowerShell treats the
$null
variable as a placeholder, you can use it scripts like the following one, which would not work if$null
were ignored.$calendar = @($null, $null, “Meeting”, $null, $null, “Team Lunch”, $null) $days = Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday" $currentDay = 0 foreach($day in $calendar) { if($day –ne $null) { "Appointment on $($days[$currentDay]): $day" } $currentDay++ }
output:
Appointment on Tuesday: Meeting Appointment on Friday: Team lunch

Most of the time your background color is different from the background of your table. Since there are spaces between the cells, those spaces will create the illusion of lines with the color of the background behind the table.
The solution is to get rid of those spaces.
Inside the table tag write:

In my case, I was using mb_split
, which uses regex. Therefore I also had to manually make sure the regex encoding was utf-8 by doing mb_regex_encoding('UTF-8');
As a side note, I also discovered by running mb_internal_encoding()
that the internal encoding wasn't utf-8, and I changed that by running mb_internal_encoding("UTF-8");

This executes the myfile.js script in mongo shell connecting to mydb database with port 27017 in localhost.
For loading external js you can write
load("/data/db/scripts/myloadjs.js")
Suppose we have two js file myFileOne.js and myFileTwo.js
myFileOne.js
print('From file 1');
load('myFileTwo.js'); // Load other js file .
myFileTwo.js
print('From file 2');

Good luck!
DTO
is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.
DTO
should only contain private fields for your data, getters, setters, and constructors.DTO
is not recommended to add business logic methods to such classes, but it is OK to add some util methods.DAO
is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).
Here is an example of how the DAO and DTO interfaces would look like:
interface PersonDTO {
String getName();
void setName(String name);
//.....
}
interface PersonDAO {
PersonDTO findById(long id);
void save(PersonDTO person);
//.....
}
The MVC
is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.
As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.
IF EXISTS(SELECT 1 FROM sys.columns
WHERE Name = N'columnName'
AND Object_ID = Object_ID(N'schemaName.tableName'))
This should be the fairly easier way and straight forward solution to this problem. I have used this multiple times for similar scenarios. It works like a charm, no doubts on that.
I had this issue after restoring a hard drive from a backup.
My problem: I could check & see my remote (using git remote -v), but when I executed git push origin master, it returned : Permission denied (publickey). fatal: Could not read from remote repository.
I already had an SSH folder and SSH keys, and adding them via Terminal (ssh-add /path/to/my-ssh-folder/id_rsa
) successfully added my identity, but I still couldn't push and still got the same error. Generating a new key was a bad idea for me, because it was tied to other very secure permissions on AWS.
It turned out the link between the key and my Github profile had broken.
Solution: Re-adding the key to Github in Profile > Settings > SSH and GPG keys resolved the issue.
Also: My account had 2-factor authentication set up. When this is the case, if Terminal requests credentials, use your username - but NOT your Github password. For 2-factor authentication, you need to use your authentication code (for me, this was generated by Authy on my phone, and I had to copy it into Terminal for the pw).
I believe its just a property as you access it as a property.
String[] s = new String[]{"abc","def","ghi"}
System.out.println(s.length)
returns 3
if it was a method then you would call s.length()

From Microsoft's Website:
.NET Core refers to several technologies including .NET Core, ASP.NET Core and Entity Framework Core.
These technologies are different than native .NET in that they run using CoreCLR runtime (used in the Universal Windows Platform).
As you mentioned in your question, .NET Core is not only open-source, but portable as well [runs on MacOS, Windows, and Linux]
The internals of .NET Core are also optimised to not use different modules from its core library unless it is required by the application.
The simple solution would be:
while True:
age = int(input("Please enter your age: "))
if (age<=0) or (age>120):
print('Sorry, I did not understand that.Please try again')
continue
else:
if age>=18:
print("You are able to vote in the United States!")
else:
print("You are not able to vote in the United States.")
break
Explanation of above code: In order for a valid age,it should be positive and should not be more than normal physical age,say for example maximum age is 120.
Then we can ask user for age and if age input is negative or more than 120,we consider it invalid input and ask the user to try again.
Once the valid input is entered, we perform a check (using nested if-else statement) whether the age is >=18 or vice versa and print a message whether the user is eligible to vote
If you download Java Development Kit(JDK) then there is a difference as it contains native libraries which differ for different architectures:
In addition you can use 32-bit JDK(x86) on 64-bit OS. But you can not use 64-bit JDK on 32-bit OS.
At the same time you can run compiled Java classes on any JVM. It does not matter whether it 32 or 64-bit.
You can also get a direct link to a view within a folder by using "TreeValue", "TreeField" and "RootFolder".
Example:
http://sharepoint/Docs/YourLibrary/Forms/YourView.aspx?RootFolder=MyFolder&TreeField=Folders&TreeValue=MyFolder
To further explain: I have a SharePoint site, with a docs library called YourLibrary. I have a folder called MyFolder. I created a view that can be used at any level of that Library structure with a URL path of YourView.aspx Using that link, it will take me to the view I created, with all the filters and styles, but only show the results that would occur in the contents of that folder in RootFolder and TreeValue.
In my case, the C:\Users\{user}\AppData\local\npm
files were hidden, so I was not able to find & delete the trouble directory. Took me DAYS to realize this!
So double check to un-hide any folders so you don't miss them! Here's a link to do this if you don't know how.
In the case that you not only want to exclude a list of special characters, but to exclude all characters that are not letters or numbers, I would suggest that you use a char type comparison approach.
For each character in the String, I would check if the unicode character is between "A" and "Z", between "a" and "z" or between "0" and "9". This is the vba code:
Function cleanString(text As String) As String
Dim output As String
Dim c 'since char type does not exist in vba, we have to use variant type.
For i = 1 To Len(text)
c = Mid(text, i, 1) 'Select the character at the i position
If (c >= "a" And c <= "z") Or (c >= "0" And c <= "9") Or (c >= "A" And c <= "Z") Then
output = output & c 'add the character to your output.
Else
output = output & " " 'add the replacement character (space) to your output
End If
Next
cleanString = output
End Function
The Wikipedia list of Unicode characers is a good quick-start if you want to customize this function a little more.
This solution has the advantage to be functionnal even if the user finds a way to introduce new special characters. It also faster than comparing two lists together.
Changing the above options form Help menu didn't work for me. You have edit idea.properties file and change to some large no.

Try to assign the image that way instead:

I'm not really too clear what you are asking, but using the -f
command line option just specifies a file - it doesn't tell make to change directories. If you want to do the work in another directory, you need to cd
to the directory:
clean:
cd gtest-1.4.0 && $(MAKE) clean
Note that each line in Makefile
runs in a separate shell, so there is no need to change the directory back.
This is the best thing I've found so far - shows you the symlinks in the current directory, recursively, but without following them, displayed with full paths and other information:
find ./ -type l -print0 | xargs -0 ls -plah
outputs looks about like this:
lrwxrwxrwx 1 apache develop 99 Dec 5 12:49 ./dir/dir2/symlink1 -> /dir3/symlinkTarget
lrwxrwxrwx 1 apache develop 81 Jan 10 14:02 ./dir1/dir2/dir4/symlink2 -> /dir5/whatever/symlink2Target
etc...
I prefer to solve this in the classic way, creating a new array of my desired data type:
List<MyNewType> newArray = new ArrayList<>();
myOldArray.forEach(info -> newArray.add(objectMapper.convertValue(info, MyNewType.class)));
As of Python 3.2 unittest.TestCase.assertItemsEqual
(doc) has been replaced by unittest.TestCase.assertCountEqual
(doc) which does exactly what you are looking for, as you can read from the python standard library documentation. The method is somewhat misleadingly named but it does exactly what you are looking for.
a and b have the same elements in the same number, regardless of their order
Here a simple example which compares two lists having the same elements but in a different order.
assertCountEqual
the test will succeedassertListEqual
the test will fail due to the order difference of the two listsHere a little example script.
import unittest
class TestListElements(unittest.TestCase):
def setUp(self):
self.expected = ['foo', 'bar', 'baz']
self.result = ['baz', 'foo', 'bar']
def test_count_eq(self):
"""Will succeed"""
self.assertCountEqual(self.result, self.expected)
def test_list_eq(self):
"""Will fail"""
self.assertListEqual(self.result, self.expected)
if __name__ == "__main__":
unittest.main()
Side Note : Please make sure that the elements in the lists you are comparing are sortable.
Here is a solution using observables.
waitForElementToAppear(elementId) {
return Observable.create(function(observer) {
var el_ref;
var f = () => {
el_ref = document.getElementById(elementId);
if (el_ref) {
observer.next(el_ref);
observer.complete();
return;
}
window.requestAnimationFrame(f);
};
f();
});
}
Now you can write
waitForElementToAppear(elementId).subscribe(el_ref => doSomethingWith(el_ref);
Any other places you use TimerEventProcessor or Counter?
Anyway, you can not rely on the Event being exactly delivered one per second. The time may vary, and the system will not make sure the average time is correct.
So instead of _Counter, you should use:
// when starting the timer:
DateTime _started = DateTime.UtcNow;
// in TimerEventProcessor:
seconds = (DateTime.UtcNow-started).TotalSeconds;
Label.Text = seconds.ToString();
Note: this does not solve the Problem of TimerEventProcessor being called to often, or _Counter incremented to often. it merely masks it, but it is also the right way to do it.
More elegant approach:
echo "Memory usage for PID <>:"; for mem in {Private,Rss,Shared,Swap,Pss};do grep $mem /proc/<pid>/smaps | awk -v mem_type="$mem" '{i=i+$2} END {print mem_type,"memory usage:"i}' ;done
In English:
It's a
List
of some type that extends the classHasWord
, includingHasWord
In general the ?
in generics means any class. And the extends SomeClass
specifies that that object must extend SomeClass
(or be that class).
I found a very weird thing in Java today, so it goes like -
If you are inputting more than 1 thing from the user, say
Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
double d = sc.nextDouble();
String s = sc.nextLine();
System.out.println(i);
System.out.println(d);
System.out.println(s);
So, it might look like if we run this program, it will ask for these 3 inputs and say our input values are 10, 2.5, "Welcome to java" The program should print these 3 values as it is, as we have used nextLine() so it shouldn't ignore the text after spaces that we have entered in our variable s
But, the output that you will get is -
10
2.5
And that's it, it doesn't even prompt for the String input. Now I was reading about it and to be very honest there are still some gaps in my understanding, all I could figure out was after taking the int input and then the double input when we press enter, it considers that as the prompt and ignores the nextLine().
So changing my code to something like this -
Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
double d = sc.nextDouble();
sc.nextLine();
String s = sc.nextLine();
System.out.println(i);
System.out.println(d);
System.out.println(s);
does the job perfectly, so it is related to something like "\n" being stored in the keyboard buffer in the previous example which we can bypass using this.
Please if anybody knows help me with an explanation for this.
Old question, and the posted answers work great. I'll chime in with another option though.

I went the way of jQuery's .parseXML()
however found that the XML path syntax of 'Page[Name="test"] > controls > test'
wouldn't work (if anyone knows why please shout out!).
Instead I chained together the individual .find()
results into something that looked like this:
$xmlDoc.find('Page[Name="test"]')
.find('contols')
.find('test')
The result achieves the same as what I would expect the one shot find.
Look at the installation instructions for node-gyp - you can't just npm install node-gyp
. I see you've installed Visual C++, but there's more to it.
What version of windows do you have? If I knew that I might be able to tell you which part of the node-gyp instructions you didn't do, but check them out and you should be able to figure it out. I've gone through a bit of pain for this stuff too.
Check the response data-body, whether actual data is present and a data-dump appears to be well-formatted.
In most cases your json.loads
- JSONDecodeError: Expecting value: line 1 column 1 (char 0)
error is due to :
Ultimately the error tells you that at the very first position the string already doesn't conform to JSON.
As such, if parsing fails despite having a data-body that looks JSON like at first glance, try replacing the quotes of the data-body:
import sys, json
struct = {}
try:
try: #try parsing to dict
dataform = str(response_json).strip("'<>() ").replace('\'', '\"')
struct = json.loads(dataform)
except:
print repr(resonse_json)
print sys.exc_info()
Note: Quotes within the data must be properly escaped
FirebaseInstanceIdService is now deprecated. you should get the Token in the onNewToken method in the FirebaseMessagingService.
I believe that is is a move operator. operator=
is the assignment operator, say vector x = vector y
. The clear()
function call sounds like as if it is deleting the contents of the vector to prevent a memory leak. The operator returns a pointer to the new vector.
This way,
std::vector<int> a(100, 10);
std::vector<int> b = a;
for(unsigned int i = 0; i < b.size(); i++)
{
std::cout << b[i] << ' ';
}
Even though we gave vector a values, vector b has the values. It's the magic of the operator=()
!
Consider the following simple Python script:
import time
import sys
for i in range(5):
print(i),
#sys.stdout.flush()
time.sleep(1)
This is designed to print one number every second for five seconds, but if you run it as it is now (depending on your default system buffering) you may not see any output until the script completes, and then all at once you will see 0 1 2 3 4
printed to the screen.
This is because the output is being buffered, and unless you flush sys.stdout
after each print
you won't see the output immediately. Remove the comment from the sys.stdout.flush()
line to see the difference.

Markus raised a great point. I decided to look up the autocomplete
attribute and got the following:
The only downside to using this attribute is that it is not standard (it works in IE and Mozilla browsers), and would cause XHTML validation to fail. I think this is a case where it's reasonable to break validation however. (source)
So I would have to say that although it doesn't work 100% across the board it is handled in the major browsers so its a great solution.
You can also group multiple commands in the one liner
[ -f "filename" ] || ( echo test1 && echo test2 && echo test3 )
or
[ -f "filename" ] || { echo test1 && echo test2 && echo test3 ;}
If filename doesn't exit, the output will be
test1
test2
test3

you need a tiny bit of Javascript.
<script type="text/javascript">

alert("Hi there");
}

This is only slightly different from Adam's answer. The effective difference is that this one alerts when the browser considers the page fully loaded, while Adam's alerts when the browser scans part the <script>
tag in the text. The difference is with, for example, images, which may continue loading in parallel for a while.
You shouldn't change the npm registry using .bat

Instead try to use modify the .npmrc

You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:
public class ProgramViwer : Form{
public ProgramViwer()
{
InitializeComponent();
Load += new EventHandler(ProgramViwer_Load);
}
private void ProgramViwer_Load(object sender, System.EventArgs e)
{
formPanel.Controls.Clear();
formPanel.Controls.Add(wel);
}
}
You have two options:
1. Share via ?Boot
function in App\Providers\AppServiceProvider
:
public function boot()
{
view()->share('key', 'value');
}
And access $key
variable in any view file.
Note
: Remember that you can't access current Session
, Auth
, Route
data here. This option is good only if you want to share static data. Suppose you want to share some data based on the current user , route, or any custom session variable you won't be able to do with this.
2. Use of a helper class:
Create a helper class anywhere in your application and register it in Alias array in app.php
file in config
folder.
'aliases' => [
...,
'Helper' => App\HelperClass\Helper::class,
],
and create Helper.php
in HelperClass folder within App folder:
namespace App\HelperClass;
class Helper
{
public static function Sample()
{
//Your Code Here
}
}
and access it anywhere like Helper::Sample()
.
You will not be restricted
here to use Auth
, Route
, Session
, or any other classes.

You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".
You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server
and this is the function I'm using to write cross domain headers:
func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
// Cross domain headers
if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
w.Header().Set("Access-Control-Allow-Headers", acrh[0])
}
w.Header().Set("Access-Control-Allow-Credentials", "True")
if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
w.Header().Set("Access-Control-Allow-Origin", acao[0])
} else {
if _, oko := req.Header["Origin"]; oko {
w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
} else {
w.Header().Set("Access-Control-Allow-Origin", "*")
}
}
w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
w.Header().Set("Connection", "Close")
}
Actually, I've seen this sort of thing used in BIRT reports. The query passed to the BIRT runtime is of the form:
select a,b,c from t where a = ?
and the '?' is replaced at runtime by an actual parameter value selected from a drop-down box. The choices in the drop-down are given by:
select distinct a from t
union all
select '*' from sysibm.sysdummy1
so that you get all possible values plus "*
". If the user selects "*
" from the drop down box (meaning all values of a should be selected), the query has to be modified (by Javascript) before being run.
Since the "?" is a positional parameter and MUST remain there for other things to work, the Javascript modifies the query to be:
select a,b,c from t where ((a = ?) or (1==1))
That basically removes the effect of the where clause while still leaving the positional parameter in place.
I've also seen the AND case used by lazy coders whilst dynamically creating an SQL query.
Say you have to dynamically create a query that starts with select * from t
and checks:
some people would add the first with a WHERE and subsequent ones with an AND thus:
select * from t where name = 'Bob' and salary > 20000
Lazy programmers (and that's not necessarily a bad trait) wouldn't distinguish between the added conditions, they'd start with select * from t where 1=1
and just add AND clauses after that.
select * from t where 1=1 and name = 'Bob' and salary > 20000
You cannot add style to an SVG <g>
element. Its only purpose is to group children. That means, too, that style attributes you give to it are given down to its children, so a fill="green"
on the <g>
means an automatic fill="green"
on its child <rect>
(as long as it has no own fill
specification).
Your only option is to add a new <rect>
to the SVG and place it accordingly to match the <g>
children's dimensions.
If you want a way to iterate the item pairs of a dictionary that works with both Python 2 and 3, try something like this:
DICT_ITER_ITEMS = (lambda d: d.iteritems()) if hasattr(dict, 'iteritems') else (lambda d: iter(d.items()))
Use it like this:
for key, value in DICT_ITER_ITEMS(myDict):
# Do something with 'key' and/or 'value'.
You can use the standard HTTP_PROXY
environment var. Simply set it to the URL of your proxy. Many operating systems already set this variable for you.
Just export the variable, then you don't have to type it all the time.
export HTTP_PROXY="http://johndoeproxy.cu:8080"
Then you can do composer update
normally.
You have multiple options:
background-size: 100% 100%;
- image gets stretched (aspect ratio may be preserved, depending on browser)background-size: contain;
- image is stretched without cutting it while preserving aspect ratiobackground-size: cover;
- image is completely covering the element while preserving aspect ratio (image can be cut off)/edit: And now, there is even more: https://alligator.io/css/cropping-images-object-fit
Here are screenshots for some browsers to show their differences.
background-size: 100% 100%;
produces the least predictable result.Note that if you're not doing math, there's nothing wrong with asserting exact floating point values. For instance:
public interface Foo {
double getDefaultValue();
}
public class FooImpl implements Foo {
public double getDefaultValue() { return Double.MIN_VALUE; }
}
In this case, you want to make sure it's really MIN_VALUE
, not zero or -MIN_VALUE
or MIN_NORMAL
or some other very small value. You can say
double defaultValue = new FooImpl().getDefaultValue();
assertEquals(Double.MIN_VALUE, defaultValue);
but this will get you a deprecation warning. To avoid that, you can call assertEquals(Object, Object)
instead:
// really you just need one cast because of autoboxing, but let's be clear
assertEquals((Object)Double.MIN_VALUE, (Object)defaultValue);
And, if you really want to look clever:
assertEquals(
Double.doubleToLongBits(Double.MIN_VALUE),
Double.doubleToLongBits(defaultValue)
);
Or you can just use Hamcrest fluent-style assertions:
// equivalent to assertEquals((Object)Double.MIN_VALUE, (Object)defaultValue);
assertThat(defaultValue, is(Double.MIN_VALUE));
If the value you're checking does come from doing some math, though, use the epsilon.

Selector Context By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function. For example, to do a search within an event handler, the search can be restricted like so:
$( "div.foo" ).click(function() {
$( "span", this ).addClass( "bar" );
});
When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.
So for your example I would suggest something like:
$("div", ".container").each(function(){
//do whatever
});
stock an increment in the .data ()
of element scrolled, you will then be able to test number of times the scroll reached top.
Found this thread when I couldn't load a json-file
with ES6 TypeScript 2.6

Like you say, os.path.join
joins paths based on the current os. posixpath
is the underlying module that is used on posix systems under the namespace os.path
:
>>> os.path.join is posixpath.join
True
>>> posixpath.join('/media/', 'js/foo.js')
'/media/js/foo.js'
So you can just import and use posixpath.join
instead for urls, which is available and will work on any platform.
Edit: @Pete's suggestion is a good one, you can alias the import for increased readability
from posixpath import join as urljoin
Edit: I think this is made clearer, or at least helped me understand, if you look into the source of os.py
(the code here is from Python 2.7.11, plus I've trimmed some bits). There's conditional imports in os.py
that picks which path module to use in the namespace os.path
. All the underlying modules (posixpath
, ntpath
, os2emxpath
, riscospath
) that may be imported in os.py
, aliased as path
, are there and exist to be used on all systems. os.py
is just picking one of the modules to use in the namespace os.path
at run time based on the current OS.

First things first, hover the mouse over the grey area below. Not part of the answer, but absolutely has to be said:
If you have a shell script that does "checkout, build, deploy" all by itself, then why are you using Jenkins? You are foregoing all the features of Jenkins that make it what it is. You might as well have a cron or an SVN post-commit hook call the script directly. Jenkins performing the SVN checkout itself is crucial. It allows the builds to be triggered only when there are changes (or on timer, or manual, if you prefer). It keeps track of changes between builds. It shows those changes, so you can see which build was for which set of changes. It emails committers when their changes caused successful or failed build (again, as configured as you prefer). It will email committers when their fixes fixed the failing build. And more and more. Jenkins archiving the artifacts also makes them available, per build, straight off Jenkins. While not as crucial as the SVN checkout, this is once again an integral part of what makes it Jenkins. Same with deploying. Unless you have a single environment, deployment usually happens to multiple environments. Jenkins can keep track of which environment a specific build (with specific set of SVN changes) is deployed it, through the use of Promotions. You are foregoing all of this. It sounds like you are told "you have to use Jenkins" but you don't really want to, and you are doing it just to get your bosses off your back, just to put a checkmark "yes, I've used Jenkins"
The short answer is: the exit code of last command of the Jenkin's Execute Shell build step is what determines the success/failure of the Build Step. 0
- success, anything else
- failure.
Note, this is determining the success/failure of the build step, not the whole job run. The success/failure of the whole job run can further be affected by multiple build steps, and post-build actions and plugins.
You've mentioned Build step 'Execute shell' marked build as failure
, so we will focus just on a single build step. If your Execute shell build step only has a single line that calls your shell script, then the exit code of your shell script will determine the success/failure of the build step. If you have more lines, after your shell script execution, then carefully review them, as they are the ones that could be causing failure.
Finally, have a read here Jenkins Build Script exits after Google Test execution. It is not directly related to your question, but note that part about Jenkins launching the Execute Shell build step, as a shell script with /bin/sh -xe
The -e
means that the shell script will exit with failure, even if just 1 command fails, even if you do error checking for that command (because the script exits before it gets to your error checking). This is contrary to normal execution of shell scripts, which usually print the error message for the failed command (or redirect it to null and handle it by other means), and continue.
To circumvent this, add set +e
to the top of your shell script.
Since you say your script does all it is supposed to do, chances are the failing command is somewhere at the end of the script. Maybe a final echo? Or copy of artifacts somewhere? Without seeing the full console output, we are just guessing.
Please post the job run's console output, and preferably the shell script itself too, and then we could tell you exactly which line is failing.
If you want to have your arguments C style (array of arguments + number of arguments) you can use $@
and $#
.
$#
gives you the number of arguments.
$@
gives you all arguments. You can turn this into an array by args=("$@")
.
So for example:
args=("$@")
echo $# arguments passed
echo ${args[0]} ${args[1]} ${args[2]}
Note that here ${args[0]}
actually is the 1st argument and not the name of your script.
This page may give you some hints - http://www.zanthan.com/itymbi/archives/000337.html
There may be a subtle bug in the body of that method that javac fails to spot. Difficult to diagnose unless you post the whole method here.
You could start by declaring as many variables as possible as final... that would have caught the bug mentioned on the zanthan site, and is often a good practice anyways.
you can also use this code...
datePicker = (DatePicker) findViewById(R.id.schedule_datePicker);
int day = datePicker.getDayOfMonth();
int month = datePicker.getMonth() + 1;
int year = datePicker.getYear();
SimpleDateFormat dateFormatter = new SimpleDateFormat("MM-dd-yyyy");
Date d = new Date(year, month, day);
String strDate = dateFormatter.format(d);
Casting to an int
truncates the value. Adding 0.5
causes it to do proper rounding.
int y = (int)(x + 0.5);
The basic setup of decorators is like this:
InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);
The key issue in this snippet is the value of encoding
. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.
For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.
Most network protocols use a header or other metadata to explicitly note the character encoding.
In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.
Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!
Remember that Constructor of an object is called immediately after the memory is allocated for that object and whereas the destructor is called just before deallocating the memory of that object.
From James Gosling in "The Java Programming Language":

>>> a = 'ZENOVW'
>>> b = sorted(a)
>>> print b
['E', 'N', 'O', 'V', 'W', 'Z']
sorted

>>> c = ''.join(b)
which joins the items of b
together with an empty string ''
in between each item.
>>> print c

Although the previous answers are all valid answers - it might be advisable to append all these to a documentFragmnet first, then append that document fragment as an element after...
See John Resig's thoughts on the matter...
Something along the lines of:
var frag = document.createDocumentFragment();
for(item in data.Events)
{
var option = document.createElement("option");
option.setAttribute("value", data.Events[item].Key);
option.innerText = data.Events[item].Value;
frag.appendChild(option);
}
eventDrop.empty();
eventDrop.append(frag);
I could find this solution and is working fine:
cd /Applications/Python\ 3.7/
./Install\ Certificates.command
this may help
Response.Write("<script>");
Response.Write("window.open('../Inventory/pages/printableads.pdf', '_newtab');");
Response.Write("</script>");
When you created the WebForm, did you select the Master page it is attached to in the "Add New Item" dialog itself ? Or did you attach it manually using the MasterPageFile
attribute of the @Page
directive ? If it was the latter, it might explain the error message you receive.
VS automatically inserts certain markup in each kind of page. If you select the MasterPage at the time of page creation itself, it does not generate any markup except the @Page
declaration and the top level Content control.
The heredoc solutions are certainly the most common way to do this. Other common solutions are:
echo 'line 1, '"${kernel}"' line 2, line 3, '"${distro}"' line 4' > /etc/myconfig.conf
and
exec 3>&1 # Save current stdout exec > /etc/myconfig.conf echo line 1, ${kernel} echo line 2, echo line 3, ${distro} ... exec 1>&3 # Restore stdout
You could use svcutil.exe to generate client code. This would include the definition of the service contract and any data contracts and fault contracts required.
Then, simply delete the client code: classes that implement the service contracts. You'll then need to implement them yourself, in your service.
Looking at http.Request you can find the following member variables:
// HTTP defines that header names are case-insensitive.
// The request parser implements this by canonicalizing the
// name, making the first character and any characters
// following a hyphen uppercase and the rest lowercase.
//
// For client requests certain headers are automatically
// added and may override values in Header.
//
// See the documentation for the Request.Write method.
Header Header
// RemoteAddr allows HTTP servers and other software to record
// the network address that sent the request, usually for
// logging. This field is not filled in by ReadRequest and
// has no defined format. The HTTP server in this package
// sets RemoteAddr to an "IP:port" address before invoking a
// handler.
// This field is ignored by the HTTP client.
RemoteAddr string
You can use RemoteAddr
to get the remote client's IP address and port (the format is "IP:port"), which is the address of the original requestor or the last proxy (for example a load balancer which lives in front of your server).
This is all you have for sure.
Then you can investigate the headers, which are case-insensitive (per documentation above), meaning all of your examples will work and yield the same result:
req.Header.Get("X-Forwarded-For") // capitalisation
req.Header.Get("x-forwarded-for") // doesn't
req.Header.Get("X-FORWARDED-FOR") // matter
This is because internally http.Header.Get
will normalise the key for you. (If you want to access header map directly, and not through Get
, you would need to use http.CanonicalHeaderKey first.)
Finally, "X-Forwarded-For"
is probably the field you want to take a look at in order to grab more information about client's IP. This greatly depends on the HTTP software used on the remote side though, as client can put anything in there if it wishes to. Also, note the expected format of this field is the comma+space separated list of IP addresses. You will need to parse it a little bit to get a single IP of your choice (probably the first one in the list), for example:
// Assuming format is as expected
ips := strings.Split("10.0.0.1, 10.0.0.2, 10.0.0.3", ", ")
for _, ip := range ips {
fmt.Println(ip)
}
will produce:
10.0.0.1
10.0.0.2
10.0.0.3
I had several inconveniences with all the solutions because I needed the type of Instant variable and the Time Zone always interfered changing everything, then combining solutions I saw that this is a good option.
LocalDate today = LocalDate.now();
Instant startDate = Instant.parse(today.toString()+"T00:00:00Z");
Instant endDate = Instant.parse(today.toString()+"T23:59:59Z");
and we have as a result
startDate = 2020-01-30T00:00:00Z
endDate = 2020-01-30T23:59:59Z
I hope it helps you
you cannot set this in javascript, you have to do this with html/css:
<style type="text/css" media="print">
@page { size: landscape; }
</style>
EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?
Function file_name_only(file_path As String) As String Dim temp As Variant temp = Split(file_path, Application.PathSeparator) file_name_only = temp(UBound(temp)) End Function
Hope this will be helpful.
Using ~*
can improve greatly on performance, with functionality of INSTR.
SELECT id FROM groups WHERE name ~* 'adm'
return rows with name that contains OR equals to 'adm'.
Sometimes, you have to send message from another Thread
to UI thread. This type of scenario occurs when you can't execute Network/IO operations on UI thread.
Below example handles that scenario.
Runnable
on UI thread. So post your Runnable
to handler on HandlerThread
Runnable
and send it back to UI thread and show a Toast
message.Solution:
HandlerThread
:requestHandler
responseHandler
and override handleMessage
methodpost
a Runnable
task on requestHandler
Runnable
task, call sendMessage
on responseHandler
sendMessage
result invocation of handleMessage
in responseHandler
.Message
and process it, update UISample code:
/* Handler thread */
HandlerThread handlerThread = new HandlerThread("HandlerThread");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());
final Handler responseHandler = new Handler(Looper.getMainLooper()) {
@Override
public void handleMessage(Message msg) {
//txtView.setText((String) msg.obj);
Toast.makeText(MainActivity.this,
"Runnable on HandlerThread is completed and got result:"+(String)msg.obj,
Toast.LENGTH_LONG)
.show();
}
};
for ( int i=0; i<5; i++) {
Runnable myRunnable = new Runnable() {
@Override
public void run() {
try {
/* Add your business logic here and construct the
Messgae which should be handled in UI thread. For
example sake, just sending a simple Text here*/
String text = "" + (++rId);
Message msg = new Message();
msg.obj = text.toString();
responseHandler.sendMessage(msg);
System.out.println(text.toString());
} catch (Exception err) {
err.printStackTrace();
}
}
};
requestHandler.post(myRunnable);
}

Does 0 count as a possible first digit? If so, then you need random.randint(0,10**n-1)
. If not, random.randint(10**(n-1),10**n-1)
. And if zero is never allowed, then you'll have to explicitly reject numbers with a zero in them, or draw n
random.randint(1,9)
numbers.
Aside: it is interesting that randint(a,b)
uses somewhat non-pythonic "indexing" to get a random number a <= n <= b
. One might have expected it to work like range
, and produce a random number a <= n < b
. (Note the closed upper interval.)
Given the responses in the comments about randrange
, note that these can be replaced with the cleaner random.randrange(0,10**n)
, random.randrange(10**(n-1),10**n)
and random.randrange(1,10)
.
if you want to add new text before or after the selected colum:
Convert to array of chars ? Sort ? Convert back to String:
String s = "edcba";
char[] c = s.toCharArray(); // convert to array of chars
java.util.Arrays.sort(c); // sort
String newString = new String(c); // convert back to String
System.out.println(newString); // "abcde"
Socks4 is a very simple protocol to implement. You listen for the initial connection, connect to the host/port that was requested by the client, send the success code to the client then forward the outgoing and incoming streams across sockets.
If you go with HTTP you'll have to read and possibly set/remove some HTTP headers so that's a little more work.
If I remember correctly, SSL will work across HTTP and Socks proxies. For a HTTP proxy you implement the CONNECT verb, which works much like the socks4 as described above, then the client opens the SSL connection across the proxied tcp stream.
You need to explicitly ask for the content type.
Add this line:
request.ContentType = "application/json; charset=utf-8";
