If you just need this for debugging to see how the XML looks like, then instead of print(xml.etree.ElementTree.tostring(e))
you can use dump
like this:
xml.etree.ElementTree.dump(e)
And this works both with Element
and ElementTree
objects as e
, so there should be no need for getroot
.
The documentation of dump
says:
xml.etree.ElementTree.dump(elem)
Writes an element tree or element structure to
sys.stdout
. This function should be used for debugging only.The exact output format is implementation dependent. In this version, it’s written as an ordinary XML file.
elem
is an element tree or an individual element.Changed in version 3.8: The
dump()
function now preserves the attribute order specified by the user.
Similar answer to Gunnar, with more complete example: You can even transparently return the whole thing:
function dumpArguments(...args) {
for (var i = 0; i < args.length; i++)
console.log(args[i]);
return args;
}
dumpArguments("foo", "bar", true, 42, ["yes", "no"], { 'banana': true });
Output:
foo
bar
true
42
["yes","no"]
{"banana":true}
Both do one thing in common - that is serializing an Object. Serialization is used to transfer objects or to store them. But:
So Serialization is part of Marshalling.
CodeBase is information that tells the receiver of Object where the implementation of this object can be found. Any program that thinks it might ever pass an object to another program that may not have seen it before must set the codebase, so that the receiver can know where to download the code from, if it doesn't have the code available locally. The receiver will, upon deserializing the object, fetch the codebase from it and load the code from that location.
When you finish your code, you will turn it into a file with the extension .java, which can be run by double clicking it, but also throughout a console (terminal on a mac, cmd.exe on windows) which lets the user do many things. One thing is they can see console messages (System.out.print or System.out.println) which they can't see if they double click. Another thing they can do is specify parameters, so normally you would use the line
java -jar MyCode.jar
after navigating to the folder of the program with
cd C:My/Code/Location
on windows or
cd My/Code/Location
on Mac (notice that mac is less clunky) to run code, but to specify parameters you would use
java -jar MyCode.jar parameter1 parameter2
These parameters stored in the args array, which you can use in your program is you want to allow the user to control special parameters such as what file to use or how much memory the program can have. If you want to know how to use an array, you could probably find a topic on this site or just google it. Note that any number of parameters can be used.
You can do a few simple steps:
1) open terminal
2) sudo nano /.bash_profile
3) add your aliases, as example:
# some aliases
alias ll='ls -alF'
alias la='ls -A'
alias eb="sudo nano ~/.bash_profile && source ~/.bash_profile"
#docker aliases
alias d='docker'
alias dc='docker-compose'
alias dnax="docker rm $(docker ps -aq)"
#git aliases
alias g='git'
alias new="git checkout -b"
alias last="git log -2"
alias gg='git status'
alias lg="git log --pretty=format:'%h was %an, %ar, message: %s' --graph"
alias nah="git reset --hard && git clean -df"
alias squash="git rebase -i HEAD~2"
4) source /.bash_profile
Done. Use and enjoy!

jQuery's attr
method returns the value of the attribute:
The
.attr()
method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's.each()
or.map()
method.
All you need is:
$('html').attr('lang') == 'fr-FR'
However, you might want to do a case-insensitive match:
$('html').attr('lang').toLowerCase() === 'fr-fr'
jQuery's val
method returns the value of a form element.
The
.val()
method is primarily used to get the values of form elements such asinput
,select
andtextarea
. In the case of<select multiple="multiple">
elements, the.val()
method returns an array containing each selected option; if no option is selected, it returnsnull
.
You may be better off working out what value type your function or code accepts, and asking for that:
if (is.integer(aVariable))
{
do whatever
}
This may be an improvement over isnull, because it provides type checking. On the other hand, it may reduce the genericity of your code.
Alternatively, just make the function you want:
is.defined = function(x)!is.null(x)
>>> source_list = ('1','a'),('2','b'),('3','c'),('4','d')
>>> list1, list2 = zip(*source_list)
>>> list1
('1', '2', '3', '4')
>>> list2
('a', 'b', 'c', 'd')
Edit: Note that zip(*iterable)
is its own inverse:
>>> list(source_list) == zip(*zip(*source_list))
True
When unpacking into two lists, this becomes:
>>> list1, list2 = zip(*source_list)
>>> list(source_list) == zip(list1, list2)
True

Ant is already installed on some older versions of Mac OS X, so you should run ant -version
to test if it is installed before attempting to install it.
If it is not already installed, then your best bet is to install Homebrew (brew install ant
) or MacPorts (sudo port install apache-ant
), and use those tools to install Apache Ant.
Alternatively, though I would highly advise using Homebrew or MacPorts instead, you can install Apache Ant manually. To do so, you would need to:
The commands that you would need, assuming apache-ant-1.8.1-bin.tar.gz
(replace 1.8.1 with the actual version) were still in your Downloads directory, would be the following (explanatory comments included):
cd ~/Downloads # Let's get into your downloads folder.
tar -xvzf apache-ant-1.8.1-bin.tar.gz # Extract the folder
sudo mkdir -p /usr/local # Ensure that /usr/local exists
sudo cp -rf apache-ant-1.8.1-bin /usr/local/apache-ant # Copy it into /usr/local
# Add the new version of Ant to current terminal session
export PATH=/usr/local/apache-ant/bin:"$PATH"
# Add the new version of Ant to future terminal sessions
echo 'export PATH=/usr/local/apache-ant/bin:"$PATH"' >> ~/.profile
# Verify new version of ant
ant -version
I wanted to add an import path, for another project elsewhere in my workspace. MacOS Catalina 10.15.5 PyCharm Community 2020.1.1

At the bottom of that dialog, it shows 5 buttons: Plus, Minus, Pencil, Funnel, and Directory tree.
Click Directory tree. You can now use the Plus button in the new dialog to add your 'external library' search path.
If successful, you should now see the directory name in the "External Libraries" pane in the Project panel.
Many 3rd party libraries have their versions of Pair, but Java has never had such a class. The closest is the inner interface java.util.Map.Entry, which exposes an immutable key property and a possibly mutable value property.
The method is implicitly defined (i.e. generated by the compiler).
From the JLS:
In addition, if
E
is the name of anenum
type, then that type has the following implicitly declaredstatic
methods:/** * Returns an array containing the constants of this enum * type, in the order they're declared. This method may be * used to iterate over the constants as follows: * * for(E c : E.values()) * System.out.println(c); * * @return an array containing the constants of this enum * type, in the order they're declared */ public static E[] values(); /** * Returns the enum constant of this type with the specified * name. * The string must match exactly an identifier used to declare * an enum constant in this type. (Extraneous whitespace * characters are not permitted.) * * @return the enum constant with the specified name * @throws IllegalArgumentException if this enum type has no * constant with the specified name */ public static E valueOf(String name);
Why not just put an executable somewhere in my $PATH
~/.local/bin directory
is theoretically expected to be in your $PATH
.
According to these people it's a bug not adding it in the $PATH
when using systemd
.
This answer explains it more extensively.
But even if your distro includes the ~/.local/bin
directory to the $PATH
, it might be in the following form (inside ~/.profile
):
if [ -d "$HOME/.local/bin" ] ; then
PATH="$HOME/.local/bin:$PATH"
fi
which would require you to logout and login again, if the directory was not there before.
In a Form, Create a text box, with in text box properties select data tab
Default value =CurrentUser()
Current source "select table field name"
It will display current user log on name in text box / label as well as saves the user name in the table field
If you would want to change the logging level of all the loggers use the below method. This will enumerate over all the loggers and change the logging level to given level. Please make sure that you DO NOT have log4j.appender.loggerName.Threshold=DEBUG
property set in your log4j.properties
file.
public static void changeLogLevel(Level level) {
Enumeration<?> loggers = LogManager.getCurrentLoggers();
while(loggers.hasMoreElements()) {
Logger logger = (Logger) loggers.nextElement();
logger.setLevel(level);
}
}
In Other ways to get difference between date;

Here i am using angular js. In javascript you can use for loop to find.
if($scope.bechval>0 &&$scope.bechval!=undefined)
{
angular.forEach($scope.model.benhmarkghamlest, function (val, key) {
$scope.model.benhmarkghamlest[key].bechval = $scope.bechval;
});
}
else {
alert("Please sepecify Bechmark value");
}
Try this:
string.Equals(a, b, StringComparison.CurrentCultureIgnoreCase);
This is what I did for updating a Priority column value by 1 if it is >=1 in a table and in its WHERE clause using a subquery on same table to make sure that at least one row contains Priority=1 (because that was the condition to be checked while performing update) :
UPDATE My_Table
SET Priority=Priority + 1
WHERE Priority >= 1
AND (SELECT TRUE FROM (SELECT * FROM My_Table WHERE Priority=1 LIMIT 1) as t);
I know it's a bit ugly but it does works fine.
In my case, I was trying the same import in manage.py shell
. The shell was messed up with the updated db. I mean, I forgot to restart my shell after updating the DB.
To resolve the issue, I had to stop the shell by the following command:

then restart the shell by the following command:
$ python3 manage.py shell

A free and open source proxy tool that runs easily on a Mac is mitmproxy.
The website includes links to a Mac binary, as well as the source code on Github.
The docs contain a very helpful intro to loading a cert into your test device to view HTTPS traffic.
Not quite as GUI-tastic as Charles, but it does everything I need and its free and maintained. Good stuff, and pretty straightforward if you've used some command line tools before.
UPDATE: I just noticed on the website that mitmproxy is available as a homebrew install. Couldn't be easier.

To parse a Date from a String you can choose which format you would like it to have. For example:
public Date StringToDate(String s){
Date result = null;
try{
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
result = dateFormat.parse(s);
}
catch(ParseException e){
e.printStackTrace();
}
return result ;
}
If you would like to use this method now, you will have to use something like this
Date date = StringToDate("2015-12-06 17:03:00");
For more explanation you should check out http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
The first danger lies in reload(sys)
.
When you reload a module, you actually get two copies of the module in your runtime. The old module is a Python object like everything else, and stays alive as long as there are references to it. So, half of the objects will be pointing to the old module, and half to the new one. When you make some change, you will never see it coming when some random object doesn't see the change:
(This is IPython shell)
In [1]: import sys
In [2]: sys.stdout
Out[2]: <colorama.ansitowin32.StreamWrapper at 0x3a2aac8>
In [3]: reload(sys)
<module 'sys' (built-in)>
In [4]: sys.stdout
Out[4]: <open file '<stdout>', mode 'w' at 0x00000000022E20C0>
In [11]: import IPython.terminal
In [14]: IPython.terminal.interactiveshell.sys.stdout
Out[14]: <colorama.ansitowin32.StreamWrapper at 0x3a9aac8>
Now, sys.setdefaultencoding()
proper
All that it affects is implicit conversion str<->unicode
. Now, utf-8
is the sanest encoding on the planet (backward-compatible with ASCII and all), the conversion now "just works", what could possibly go wrong?
Well, anything. And that is the danger.
UnicodeError
being thrown for non-ASCII input, or does the transcoding with an error handler, which now produces an unexpected result. And since all code is tested with the default setting, you're strictly on "unsupported" territory here, and no-one gives you guarantees about how their code will behave.The app is stored in %LocalAppData%
in your %UserProfile%
. So the full path could be:
C:\Users\username\AppData\Local\GitHub
One more difference, which I've encountered in other languages for Constants is : can't initialise the constant(let) for later , should initialise as you're about to declare the constant.
For instance :
let constantValue : Int // Compile error - let declarations require an initialiser expression
Variable
var variableValue : Int // No issues
Unique Keys: The columns in which no two rows are similar
Primary Key: Collection of minimum number of columns which can uniquely identify every row in a table (i.e. no two rows are similar in all the columns constituting primary key). There can be more than one primary key in a table. If there exists a unique-key then it is primary key (not "the" primary key) in the table. If there does not exist a unique key then more than one column values will be required to identify a row like (first_name, last_name, father_name, mother_name) can in some tables constitute primary key.
Index: used to optimize the queries. If you are going to search or sort the results on basis of some column many times (eg. mostly people are going to search the students by name and not by their roll no.) then it can be optimized if the column values are all "indexed" for example with a binary tree algorithm.
well it's used to tell bootstrap how many columns are to be placed in a row depending on the screen size-
col-xs-2
would show only 2 columns in a row in extra small(xs) screen, in the same way as sm defines a small screen, md(medium sized), lg(large sized), but according to bootstrap smaller first rule, if you mention
xs-col-2 md-col-4
then 2 columns would be shown in every row for screen sizes from xs upto sm(included) and changes when it gets next size i.e. for md up to lg(included) for a better understanding of screen sizes try running them in various screen modes in chrome's developer mode(ctr+shift+i) and try various pixels or devices
Another option would be use a dictionary instead of an array:
Dim oNames As Object
Set oNames = CreateObject("Scripting.Dictionary")
'You could if need be create this automatically from an existing Array
'The 1 is just a dummy value, we just want the names as keys
oNames.Add "JOHN", 1
oNames.Add "BOB", 1
oNames.Add "JAMES", 1
oNames.Add "PHILIP", 1
As this would then get you a one-liner of
oNames.Exists("JOHN")
The advantage a dictionary provides is exact matching over partial matching from Filter
. Say if you have the original list of names in an Array, but were looking for "JO" or "PHIL" who were actually two new people in addition to the four we started with. In this case, Filter(oNAMES, "JO")
will match "JOHN" which may not be desired. With a dictionary, it won't.
Do I need to double the size of the .box div to 400px by 400px to match the new high res background image
No, but you do need to set the background-size
property to match the original dimensions:
@media (-webkit-min-device-pixel-ratio: 2),
(min-resolution: 192dpi) {
.box{
background:url('images/[email protected]') no-repeat top left;
background-size: 200px 200px;
}
}
EDIT
To add a little more to this answer, here is the retina detection query I tend to use:
@media
only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and ( min--moz-device-pixel-ratio: 2),
only screen and ( -o-min-device-pixel-ratio: 2/1),
only screen and ( min-device-pixel-ratio: 2),
only screen and ( min-resolution: 192dpi),
only screen and ( min-resolution: 2dppx) {
}
NB. This min--moz-device-pixel-ratio:
is not a typo. It is a well documented bug in certain versions of Firefox and should be written like this in order to support older versions (prior to Firefox 16).
- Source
As @LiamNewmarch mentioned in the comments below, you can include the background-size
in your shorthand background
declaration like so:
.box{
background:url('images/[email protected]') no-repeat top left / 200px 200px;
}
However, I personally would not advise using the shorthand form as it is not supported in iOS <= 6 or Android making it unreliable in most situations.

If you need just update your records in energydata
based on data in temp_energydata
, assuming that temp_enerydata
doesn't contain any new records, then try this:
UPDATE e SET e.kWh = t.kWh
FROM energydata e INNER JOIN
temp_energydata t ON e.webmeterID = t.webmeterID AND
e.DateTime = t.DateTime
Here is working sqlfiddle
But if temp_energydata
contains new records and you need to insert it to energydata
preferably with one statement then you should definitely go with the answer that Bacon Bits gave.
To get a pure hex value this might be useful. It's based on Joe's answer:
def gethex(decimal):
return hex(decimal)[2:]
I have found the following algorithm very clear and simple:
def get_powerset(some_list):
"""Returns all subsets of size 0 - len(some_list) for some_list"""
if len(some_list) == 0:
return [[]]
subsets = []
first_element = some_list[0]
remaining_list = some_list[1:]
# Strategy: get all the subsets of remaining_list. For each
# of those subsets, a full subset list will contain both
# the original subset as well as a version of the subset
# that contains first_element
for partial_subset in get_powerset(remaining_list):
subsets.append(partial_subset)
subsets.append(partial_subset[:] + [first_element])
return subsets
Another way one can generate the powerset is by generating all binary numbers that have n
bits. As a power set the amount of number with n
digits is 2 ^ n
. The principle of this algorithm is that an element could be present or not in a subset as a binary digit could be one or zero but not both.
def power_set(items):
N = len(items)
# enumerate the 2 ** N possible combinations
for i in range(2 ** N):
combo = []
for j in range(N):
# test bit jth of integer i
if (i >> j) % 2 == 1:
combo.append(items[j])
yield combo
I found both algorithms when I was taking MITx: 6.00.2x Introduction to Computational Thinking and Data Science, and I consider it is one of the easiest algorithms to understand I have seen.
Use ax.yaxis.tick_right()
for example:
from matplotlib import pyplot as plt
f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
plt.plot([2,3,4,5])
plt.show()
The files selected are stored in an array: [input].files
For example, you can access the items
// assuming there is a file input with the ID `my-input`...
var files = document.getElementById("my-input").files;
for (var i = 0; i < files.length; i++)
{
alert(files[i].name);
}
For jQuery-comfortable people, it's similarly easy
// assuming there is a file input with the ID `my-input`...
var files = $("#my-input")[0].files;
for (var i = 0; i < files.length; i++)
{
alert(files[i].name);
}
Theoretically you can't. Java memory model prevents it. However, because Java has to be implemented, there are some caveats you can use. Depends on what you can use:
If you can use native, you can allocate memory that you don not relinquish later.
If that is not available, there is a dirty little secret about java that not much people know. You can ask for a direct access array that is not managed by GC, and therefor can be easily used to make a memory leak. This is provided by DirectByteBuffer (http://download.oracle.com/javase/1.5.0/docs/api/java/nio/ByteBuffer.html#allocateDirect(int)).
If you can't use any of those, you still can make a memory leak by tricking the GC. The JVM is implemented using a Generational garbage collection. What this means is that the heap is divided into areas: young, adults and elders. An object when its created starts at the young area. As he is used more and more, he progresses into adults up to elders. An object that reaches the eldery area most likely will not be garbaged collected. You cannot be sure that an object is leaked and if you ask for a stop and clean GC it may clean it but for a long period of time he will be leaked. More info at (http://java.sun.com/docs/hotspot/gc1.4.2/faq.html)
Also, class objects are not required to be GC'ed. Might me a way to do it.
This can be a good option if you want python completion as well as other languages. https://github.com/Valloric/YouCompleteMe
The python completion is jedi based same as jedi-vim.
As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:
var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da
For Node.js v5.11.1 and below
Construct a new Buffer
and pass 'base64'
as the second argument:
var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da
If you want to be clean, you can check whether from
exists :
if (typeof Buffer.from === "function") {
// Node 5.10+
buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
// older Node versions, now deprecated
buf = new Buffer(b64string, 'base64'); // Ta-da
}
Use Range("A1").Text
instead of .Value
post comment edit:
Why?
Because the .Text
property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92
then <- Text
will return exactly what it in the cell including any formatting.
The .Value
and .Value2
properties return what's stored in the cell under the hood excluding formatting. Specially .Value2
for date types, it will return the decimal representation.
If you want to dig deeper into the meaning and performance, I just found this article
which seems like a good guide
another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage
now,
paste this code in a module

Cells(i, j).Text & vbTab & _
Cells(i, j).Value & vbTab & _
Cells(i, j).Value2

For the TL;DR, here are 2 cents and a simpler version for your questions:
WebSockets provides these benefits over HTTP:
WebSocket and HTTP protocol have been designed to solve different problems, I.E. WebSocket was designed to improve bi-directional communication whereas HTTP was designed to be stateless, distributed using a request/response model. Other than sharing the ports for legacy reasons (firewall/proxy penetration), there isn't much common ground to combine them into one protocol.
I am assuming what you are trying to achieve is to insert a line after the first few lines of of a textfile.
head -n10 file.txt >> newfile.txt
echo "your line >> newfile.txt
tail -n +10 file.txt >> newfile.txt
If you don't want to rest of the lines from the file, just skip the tail part.

In the System Variables window, check if you have a variable named PYTHONPATH. If you have one already, check that it points to the right directories. If you don't have one already, click the New button and create it.
Alternatively, you can also do below your code:-
import sys
sys.path.append("/home/me/mypy")
FYI to anyone who runs into problems, there is a bug in CSV timestamp export that I just spent a few hours working around. Some fields I needed to export were of type timestamp. It appears the CSV export option even in the current version (3.0.04 as of this posting) fails to put the grouping symbols around timestamps. Very frustrating since spaces in the timestamps broke my import. The best workaround I found was to write my query with a TO_CHAR() on all my timestamps, which yields the correct output, albeit with a little more work. I hope this saves someone some time or gets Oracle on the ball with their next release.
String id = id.substring(0,id.length()-4)
Moving the Springbootapplication(application.java) file to another package resolved the issue for me. Keep it separate from the controllers and repositories.
The following page provides a relatively good guide that requires few corrections : https://cv-tricks.com/how-to/installation-of-opencv-4-1-0-in-windows-10-from-source/
On step 8, when you are choosing generator for the project (tool used for building), don't forget to specify x64 in the second field if you need it. If you don't, you will get LNK1112 error, which is a linker error caused if one module is created with the x64 compiler, and another module is created with the x86 compiler.
Next, when choosing flags in step 9, don't forget to tick the "OPENCV_ENABLE_NONFREE", and set the path for flag "OPENCV_EXTRA_MODULES_PATH" flag. The path must be set to "modules" folder in opencv-contrib-python.
So you need both opencv, and opencv-contrib-python in order to use SIFT and SURF.
do you want to write code for that or just use command-line feature 'command redirection' as follows:
app.exe >> output.txt
as demonstrated here: http://discomoose.org/2006/05/01/output-redirection-to-a-file-from-the-windows-command-line/ (Archived at archive.org)
EDIT: link dead, here's another example: http://pcsupport.about.com/od/commandlinereference/a/redirect-command-output-to-file.htm
Your problem seems to be a missing space between your two classes in the CSS:
.area1.item
{
color:red;
}
Should be
.area1 .item
{
color:red;
}
mysql -u <user> -p -e "select * from schema.table"
using this func
private static String strDuration(long duration) {
int ms, s, m, h, d;
double dec;
double time = duration * 1.0;
time = (time / 1000.0);
dec = time % 1;
time = time - dec;
ms = (int)(dec * 1000);
time = (time / 60.0);
dec = time % 1;
time = time - dec;
s = (int)(dec * 60);
time = (time / 60.0);
dec = time % 1;
time = time - dec;
m = (int)(dec * 60);
time = (time / 24.0);
dec = time % 1;
time = time - dec;
h = (int)(dec * 24);
d = (int)time;
return (String.format("%d d - %02d:%02d:%02d.%03d", d, h, m, s, ms));
}
I imagine that trygetvalue is doing something more like:
if(myDict.ReallyOptimisedVersionofContains(someKey))
{
someVal = myDict[someKey];
return true;
}
return false;
So hopefully no try/catch anywhere.
I think it is just a method of convenience really. I generally use it as it saves a line of code or two.
Assuming the type in your example, definitely prefer to initialize fields in the constructor. The exceptional cases are:
I always think of the field listing at the top of a class as the table of contents (what is contained herein, not how it is used), and the constructor as the introduction. Methods of course are chapters.
If you don't mind creating an extra date object, you could try:
var tempDate = new Date(parseInt(item.timestamp, 10));
var visitDate = new Date (tempDate.getUTCFullYear(), tempDate.getUTCMonth(), tempDate.getUTCDate());
I do something very similar to get a date of the current month without the time.
Another option, for those of you who still stumble upon this post like I did, is to use find -exec
:
find . -type f -name '*.txt' -exec cat {} + >> output.file
In my case, I needed a more robust option that would look through multiple subdirectories so I chose to use find
. Breaking it down:
find .
Look within the current working directory.
-type f
Only interested in files, not directories, etc.
-name '*.txt'
Whittle down the result set by name
-exec cat {} +
Execute the cat command for each result. "+" means only 1 instance of cat
is spawned (thx @gniourf_gniourf)
>> output.file
As explained in other answers, append the cat-ed contents to the end of an output file.
@Adam Rosenfield's solution, although correct, could be implemented with a more lightweight circular_buffer
structure that does not invlove count
and capacity
.
The structure could only hold the following 4 pointers:
buffer
: Points to the start of the buffer in memory.buffer_end
: Points to the end of the buffer in memory.head
: Points to the end of stored data.tail
: Points to the start of stored data.We could keep the sz
attribute to allow the parametrisation of the unit of storage.
Both the count
and the capacity
values should be derive-able using the above pointers.
capacity
is straight forward, as it can be derived by dividing the distance between the buffer_end
pointer and the buffer
pointer by the unit of storage sz
(snippet below is pseudocode):
capacity = (buffer_end - buffer) / sz
For count though, things get a bit more complicated. For example, there is no way to determine whether the buffer is empty or full, in the scenario of head
and tail
pointing to the same location.
To tackle that, the buffer should allocate memory for an additional element. For example, if the desired capacity of our circular buffer is 10 * sz
, then we need to allocate 11 * sz
.
Capacity formula will then become (snippet below is pseudocode):
capacity_bytes = buffer_end - buffer - sz
capacity = capacity_bytes / sz
This extra element semantic allows us to construct conditions that evaluate whether the buffer is empty or full.
In order for the buffer to be empty, the head
pointer points to the same location as the tail
pointer:
head == tail
If the above evaluates to true, the buffer is empty.
In order for the buffer to be full, the head
pointer should be 1 element behind the tail
pointer. Thus, the space needed to cover in order to jump from the head
location to the tail
location should be equal to 1 * sz
.
tail
is larger that head
:tail - head == sz
If the above evaluates to true, the buffer is full.
head
is larger that tail
:buffer_end - head
returns the space to jump from the head
to the end of the buffer.tail - buffer
returns the space needed to jump from the start of the buffer to the `tail.head
to the tail
1 * sz
(buffer_end - head) + (tail - buffer) == sz
=> buffer_end - buffer - head + tail == sz
=> buffer_end - buffer - sz == head - tail
=> head - tail == buffer_end - buffer - sz
=> head - tail == capacity_bytes
If the above evaluates to true, the buffer is full.
Modifying @Adam Rosenfield's to use the above circular_buffer
structure:
#include <string.h>
#define CB_SUCCESS 0 /* CB operation was successful */
#define CB_MEMORY_ERROR 1 /* Failed to allocate memory */
#define CB_OVERFLOW_ERROR 2 /* CB is full. Cannot push more items. */
#define CB_EMPTY_ERROR 3 /* CB is empty. Cannot pop more items. */
typedef struct circular_buffer {
void *buffer;
void *buffer_end;
size_t sz;
void *head;
void *tail;
} circular_buffer;
int cb_init(circular_buffer *cb, size_t capacity, size_t sz) {
const int incremented_capacity = capacity + 1; // Add extra element to evaluate count
cb->buffer = malloc(incremented_capacity * sz);
if (cb->buffer == NULL)
return CB_MEMORY_ERROR;
cb->buffer_end = (char *)cb->buffer + incremented_capacity * sz;
cb->sz = sz;
cb->head = cb->buffer;
cb->tail = cb->buffer;
return CB_SUCCESS;
}
int cb_free(circular_buffer *cb) {
free(cb->buffer);
return CB_SUCCESS;
}
const int _cb_length(circular_buffer *cb) {
return (char *)cb->buffer_end - (char *)cb->buffer;
}
int cb_push_back(circular_buffer *cb, const void *item) {
const int buffer_length = _cb_length(cb);
const int capacity_length = buffer_length - cb->sz;
if ((char *)cb->tail - (char *)cb->head == cb->sz ||
(char *)cb->head - (char *)cb->tail == capacity_length)
return CB_OVERFLOW_ERROR;
memcpy(cb->head, item, cb->sz);
cb->head = (char*)cb->head + cb->sz;
if(cb->head == cb->buffer_end)
cb->head = cb->buffer;
return CB_SUCCESS;
}
int cb_pop_front(circular_buffer *cb, void *item) {
if (cb->head == cb->tail)
return CB_EMPTY_ERROR;
memcpy(item, cb->tail, cb->sz);
cb->tail = (char*)cb->tail + cb->sz;
if(cb->tail == cb->buffer_end)
cb->tail = cb->buffer;
return CB_SUCCESS;
}
public View recentView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Create a relative layout and add a button
relativeLayout = new RelativeLayout(this);

btn.setId((int)System.currentTimeMillis());
recentView = btn;
btn.setText("Click me");
relativeLayout.addView(btn);
setContentView(relativeLayout);
btn.setOnClickListener(new View.OnClickListener() {
@Overr ide
public void onClick(View view) {
//Create a textView, set a random ID and position it below the most recently added view
textView = new TextView(ActivityName.this);
textView.setId((int)System.currentTimeMillis());
layoutParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
layoutParams.addRule(RelativeLayout.BELOW, recentView.getId());
textView.setText("Time: "+System.currentTimeMillis());

This can be modified to display each element of a String array in different TextViews.
At least as of iOS 6, you can override methods in your custom cell to prevent the blue highlight. No other interaction is disabled or affected. All three must be overridden.
- (void) setHighlighted:(BOOL)highlighted
{
}
- (void) setHighlighted:(BOOL)highlighted animated:(BOOL)animated
{
}
- (void) setSelected:(BOOL)selected animated:(BOOL)animated
{
}
$.get('http://www.your_domain.com/image.jpg', imgLoaded);
function imgLoaded(){
console.log(this, 'loaded');
}
AFAIK there is no property for that in the specs, but here is a trick I’ve been using:
set the container element ( the one with display:flex
) to justify-content:space-around
Then add an extra element between the first and second item and set it to flex-grow:10
(or some other value that works with your setup)
Edit: if the items are tightly aligned it's a good idea to add flex-shrink: 10;
to the extra element as well, so the layout will be properly responsive on smaller devices.
I was tying to figure out how to do this but i could not get any answers from google. I know this is an old thread but here was my solution:
Use the following class:
class ThreadWaiter
{
private int _numThreads = 0;
private int _spinTime;
public ThreadWaiter(int SpinTime)
{
this._spinTime = SpinTime;
}
public void AddThreads(int numThreads)
{
_numThreads += numThreads;
}
public void RemoveThread()
{
if (_numThreads > 0)
{
_numThreads--;
}
}
public void Wait()
{
while (_numThreads != 0)
{
System.Threading.Thread.Sleep(_spinTime);
}
}
}
Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).
It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).
But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.
A good example: here
And a good documentation from Mozilla: here
With /^[a-zA-Z]/
you only check the first character:
^
: Assert position at the beginning of the string[a-zA-Z]
: Match a single character present in the list below:
a-z
: A character in the range between "a" and "z"A-Z
: A character in the range between "A" and "Z"If you want to check if all characters are letters, use this instead:
/^[a-zA-Z]+$/.test(str);
^
: Assert position at the beginning of the string[a-zA-Z]
: Match a single character present in the list below:
+
: Between one and unlimited times, as many as possible, giving back as needed (greedy)a-z
: A character in the range between "a" and "z"A-Z
: A character in the range between "A" and "Z"$
: Assert position at the end of the string (or before the line break at the end of the string, if any)Or, using the case-insensitive flag i
, you could simplify it to
/^[a-z]+$/i.test(str);
Or, since you only want to test
, and not match
, you could check for the opposite, and negate it:
!/[^a-z]/i.test(str);

Firstly, I don't think spaces for an id is valid.
So i'd change the id to not include spaces.
<label year="2010" month="6" id="currentMonth"> June 2010</label>
then the jquery code is simple (keep in mind, its better to fetch the jquery object once and use over and over agian)
var label = $('#currentMonth');
var month = label.attr('month');
var year = label.attr('year');
var text = label.text();
I have successfully installed Composer (and Laravel) on my shared hosting with only FTP access:
Download and install PHPShell on a shared hosting
In PHPShell's config.php
add a user and an alias:
php = "php -d suhosin.executor.include.whitelist=phar"
Log in to PHPShell and type: curl -sS https://getcomposer.org/installer | php
When successfully installed, run Composer: php composer.phar
The problem is that the tab-completion is searching your path, but all commands are not in your path.
To find the commands in your path using bash you could do something like :
for x in echo $PATH | cut -d":" -f1
; do ls $x; done
As defined by the SQL-92 Standard, when comparing two strings of differing widths, the narrower value is right-padded with spaces to make it is same width as the wider value. Therefore, all string values that consist entirely of spaces (including zero spaces) will be deemed to be equal e.g.
'' = ' ' IS TRUE
'' = ' ' IS TRUE
' ' = ' ' IS TRUE
' ' = ' ' IS TRUE
etc
Therefore, this should work regardless of how many spaces make up the some_col
value:
SELECT *
FROM T
WHERE some_col IS NULL
OR some_col = ' ';
or more succinctly:
SELECT *
FROM T
WHERE NULLIF(some_col, ' ') IS NULL;

It's really not that big of a deal. You could just make a script with the single command:
chmod a+x *.pl
And run the script after creating a perl file. Alternatively, you could open a file with a command like this:
touch filename.pl && chmod a+x filename.pl && vi filename.pl # choose your favorite editor
After you've run the Inspect by Name, select all the locations, and make use of the Apply quick fixes to all the problems drop-down, and use either (or both) of Delete unused parameter(s) and Safe Delete.
Don't forget to hit Do Refactor afterwards.
Then you'll need to run another analysis, as the refactored code will no doubt reveal more unused declarations.
Apache's Multi-Processing Modules (MPMs) are responsible for binding to network ports on the machine, accepting requests, and dispatching children to handle the requests (http://httpd.apache.org/docs/2.2/mpm.html).
They're like any other Apache module, except that just one and only one MPM must be loaded into the server at any time. MPMs are chosen during configuration and compiled into the server by using the argument --with-mpm=NAME
with the configure script where NAME
is the name of the desired MPM.
Apache will use a default MPM for each operating system unless a different one is choosen at compile-time (for instance on Windows mpm_winnt
is used by default). Here's the list of operating systems and their default MPMs:
beos
mpm_netware
mpmt_os2
prefork
(update for Apache version = 2.4: prefork
, worker
, or event
, depending on platform capabilities)mpm_winnt
To check what modules are compiled into the server use the command-line option -l
(here is the documentation). For instance on a Windows installation you might get something like:
> httpd -l
Compiled in modules:
core.c
mod_win32.c
mpm_winnt.c
http_core.c
mod_so.c
As of version 2.2 this is the list of available core features and MPM modules:
core
- Core Apache HTTP Server features that are always availablempm_common
- A collection of directives that are implemented by more than one multi-processing module (MPM)beos
- This Multi-Processing Module is optimized for BeOS.event
- An experimental variant of the standard worker MPMmpm_netware
Multi-Processing Module implementing an exclusively threaded web server optimized for Novell NetWarempmt_os2
Hybrid multi-process, multi-threaded MPM for OS/2prefork
Implements a non-threaded, pre-forking web servermpm_winnt
- This Multi-Processing Module is optimized for Windows NT.worker
- Multi-Processing Module implementing a hybrid multi-threaded multi-process web serverNow, to the difference between prefork
and worker
.
The prefork
MPM
implements a non-threaded, pre-forking web server that handles requests in a manner similar to Apache 1.3. It is appropriate for sites that need to avoid threading for compatibility with non-thread-safe libraries. It is also the best MPM for isolating each request, so that a problem with a single request will not affect any other.
The worker
MPM implements a hybrid multi-process multi-threaded server and gives better performance, hence it should be preferred unless one is using other modules that contain non-thread-safe libraries (see also this discussion or this on Serverfault).
You can do this replacing position:absolute;
by position:fixed;
.
I just went through the same problem. And found out once you have a syntax or any type of error in you javascript, the whole file don't get loaded so you cannot use any of the other functions at all.
Use the FOR command to echo a file line by line, and with the 'skip' option to miss a number of starting lines...
FOR /F "skip=1" %i in (file2.txt) do @echo %i
You could redirect the output of a batch file, containing something like...
FOR /F %%i in (file1.txt) do @echo %%i
FOR /F "skip=1" %%i in (file2.txt) do @echo %%i
Note the double % when a FOR variable is used within a batch file.
The instructions in @bsdnoobz answer are indeed helpful, but didn't get OpenCV to work on my system.
Apparently I needed to compile the library myself in order to get it to work, and not count on the pre-built binaries (which caused my programs to crash, probably due to incompatibility with my system).
I did get it to work, and wrote a comprehensive guide for compiling and installing OpenCV, and configuring Netbeans to work with it.
For completeness, it is also provided below.
When I first started using OpenCV, I encountered two major difficulties:
I read many tutorials and "how-to" articles, but none was really comprehensive and thorough. Eventually I succeeded in setting up the environment; and after a while of using this (great) library, I decided to write this small tutorial, which will hopefully help others.
The are three parts to this tutorial:
The environment I use is: Windows 7, OpenCV 2.4.0, Netbeans 7 and MinGW 3.20 (with compiler gcc 4.6.2).
Assumptions: You already have MinGW and Netbeans installed on your system.
When downloading OpenCV, the archive actually already contains pre-built binaries (compiled libraries and DLL's) in the 'build' folder. At first, I tried using those binaries, assuming somebody had already done the job of compiling for me. That didn't work.
Eventually I figured I have to compile the entire library on my own system in order for it to work properly.
Luckily, the compilation process is rather easy, thanks to CMake. CMake (stands for Cross-platform Make) is a tool which generates makefiles specific to your compiler and platform. We will use CMake in order to configure our building and compilation settings, generate a 'makefile', and then compile the library.
The steps are:
c:/opencv/
.c:/opencv/
.c:/opencv/release
.c:/opencv/release/
.mingw32-make
and press enter. This should start the compilation
process.C:/opencv/release/bin
to the system PATH. This will make sure our programs can find the
needed DLL's to run.Netbeans should be told where to find the header files and the compiled libraries (which were created in the previous section).
The header files are needed for two reasons: for compilation and for code completion. The compiled libraries are needed for the linking stage.
Note: In order for debugging to work, the OpenCV DLL's should be available, which is why we added the directory which contains them to the system PATH (previous section, step 5.4).
First, you should verify that Netbeans is configured correctly to work with
MinGW. Please see the screenshot below and verify your settings are correct
(considering paths changes according to your own installation). Also note
that the make
command should be from msys and not from Cygwin.
Next, for each new project you create in Netbeans, you should define the include path (the directory which contains the header files), the libraries path and the specific libraries you intend to use. Right-click the project name in the 'projects' pane, and choose 'properties'. Add the include path (modify the path according to your own installation):
Add the libraries path:
Add the specific libraries you intend to use. These libraries will be
dynamically linked to your program in the linking stage. Usually you will need
the core
library plus any other libraries according to the specific needs of
your program.
That's it, you are now ready to use OpenCV!
Here are the general steps you need to complete in order to install OpenCV and use it with Netbeans:
Here is a small example program which draws the text "Hello World : )" on a GUI window. You can use it to check that your installation works correctly. After compiling and running the program, you should see the following window:
#include "opencv2/opencv.hpp"

If you want to SELECT
based on the value of another SELECT
, then you probably want a "subselect":
http://beginner-sql-tutorial.com/sql-subquery.htm
For example, (from the link above):
You want the first and last names from table "student_details" ...
But you only want this information for those students in "science" class:
SELECT id, first_name
FROM student_details
WHERE first_name IN (SELECT first_name
FROM student_details
WHERE subject= 'Science');
Frankly, I'm not sure this is what you're looking for or not ... but I hope it helps ... at least a little...
IMHO...

There is are multiple ways to execute the commands or script in the multiple remote Linux machines.
One simple & easiest way is via pssh (parallel ssh program)
pssh: is a program for executing ssh in parallel on a number of hosts. It provides features such as sending input to all of the processes, passing a password to ssh, saving the output to files, and timing out.
Example & Usage:
Connect to host1 and host2, and print "hello, world" from each:
pssh -i -H "host1 host2" echo "hello, world"
Run commands via a script on multiple servers:
pssh -h hosts.txt -P -I<./commands.sh
Usage & run a command without checking or saving host keys:
pssh -h hostname_ip.txt -x '-q -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey -o PubkeyAuthentication=yes' -i 'uptime; hostname -f'
If the file hosts.txt has a large number of entries, say 100, then the parallelism option may also be set to 100 to ensure that the commands are run concurrently:
pssh -i -h hosts.txt -p 100 -t 0 sleep 10000
Options:
-I: Read input and sends to each ssh process.
-P: Tells pssh to display output as it arrives.
-h: Reads the host's file.
-H : [user@]host[:port] for single-host.
-i: Display standard output and standard error as each host completes
-x args: Passes extra SSH command-line arguments
-o option: Can be used to give options in the format used in the configuration file.(/etc/ssh/ssh_config) (~/.ssh/config)
-p parallelism: Use the given number as the maximum number of concurrent connections
-q Quiet mode: Causes most warning and diagnostic messages to be suppressed.
-t: Make connections time out after the given number of seconds. 0 means pssh will not timeout any connections
When ssh'ing to the remote machine, how to handle when it prompts for RSA fingerprint authentication.
Disable the StrictHostKeyChecking to handle the RSA authentication prompt.

I have jus implement this library:https://github.com/jose78/go-collection. This is an example about how to use the Foreach loop:
package main
import (
"fmt"
col "github.com/jose78/go-collection/collections"
)
type user struct {
name string
age int
id int
}
func main() {
newList := col.ListType{user{"Alvaro", 6, 1}, user{"Sofia", 3, 2}}
newList = append(newList, user{"Mon", 0, 3})
newList.Foreach(simpleLoop)
if err := newList.Foreach(simpleLoopWithError); err != nil{
fmt.Printf("This error >>> %v <<< was produced", err )
}
}
var simpleLoop col.FnForeachList = func(mapper interface{}, index int) {
fmt.Printf("%d.- item:%v\n", index, mapper)
}
var simpleLoopWithError col.FnForeachList = func(mapper interface{}, index int) {
if index > 1{
panic(fmt.Sprintf("Error produced with index == %d\n", index))
}
fmt.Printf("%d.- item:%v\n", index, mapper)
}
The result of this execution should be:
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}
2.- item:{Mon 0 3}
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}

Note: there is no guarantee this code will work in future versions of the .Net framework. Using private .Net framework internals as done here through reflection is probably not good overall. Use the interop solution mentioned at the bottom, as the Windows API is less likely to change.
If you are looking for a Folder picker that looks more like the Windows 7 dialog, with the ability to copy and paste from a textbox at the bottom and the navigation pane on the left with favorites and common locations, then you can get access to that in a very lightweight way.
The FolderBrowserDialog UI is very minimal:
But you can have this instead:
Here's a class that opens a Vista-style folder picker using the .Net private IFileDialog
interface, without directly using interop in the code (.Net takes care of that for you). It falls back to the pre-Vista dialog if not in a high enough Windows version. Should work in Windows 7, 8, 9, 10 and higher (theoretically).

I developed this as a cleaned up version of .NET Win 7-style folder select dialog by Bill Seddon of lyquidity.com (I have no affiliation). I wrote my own because his solution requires an additional Reflection class that isn't needed for this focused purpose, uses exception-based flow control, doesn't cache the results of its reflection calls. Note that the nested static VistaDialog
class is so that its static reflection variables don't try to get populated if the Show
method is never called.
It is used like so in a Windows Form:
var dialog = new FolderSelectDialog {
InitialDirectory = musicFolderTextBox.Text,
Title = "Select a folder to import music from"
};
if (dialog.Show(Handle)) {
musicFolderTextBox.Text = dialog.FileName;
}
You can of course play around with its options and what properties it exposes. For example, it allows multiselect in the Vista-style dialog.
Also, please note that Simon Mourier gave an answer that shows how to do the exact same job using interop against the Windows API directly, though his version would have to be supplemented to use the older style dialog if in an older version of Windows. Unfortunately, I hadn't found his post yet when I worked up my solution. Name your poison!
In Windows, capitalization in paths doesn't matter. In Linux it does.
When you autoload, use "Foo" not "foo".
I believe that will do the trick.
I think it works when you take it out of autoloading because codeigniter is smart enough to figure out the capitalization in the path and classes are case independent in php.
Ideally I would avoid generating links in you code behind altogether as your code will need recompiling every time you want to make a change to the 'markup' of each of those links. If you have to do it I would not embed your javascript 'calls' inside your HTML, it's a bad practice altogether, your markup should describe your document not what it does, thats the job of your javascript.
Use an approach where you have a specific id for each element (or class if its common functionality) and then use Progressive Enhancement to add the event handler(s), something like:
[c# example only probably not the way you're writing out your js]
Response.Write("<a href=\"/link/for/javascriptDisabled/Browsers.aspx\" id=\"uxAncMyLink\">My Link</a>");
[Javascript]
document.getElementById('uxAncMyLink').onclick = function(e){
// do some stuff here
return false;
}
That way your code won't break for users with JS disabled and it will have a clear seperation of concerns.
Hope that is of use.
To get the Unix time (seconds since January 1, 1970):

It looks like the answer is at least 12 million if you have a beefy server, your server software is optimized for it, you have enough clients. If you test from one client to one server, the number of port numbers on the client will be one of the obvious resource limits (Each TCP connection is defined by the unique combination of IP and port number at the source and destination).
(You need to run multiple clients as otherwise you hit the 64K limit on port numbers first)
When it comes down to it, this is a classic example of the witticism that "the difference between theory and practise is much larger in practise than in theory" - in practise achieving the higher numbers seems to be a cycle of a. propose specific configuration/architecture/code changes, b. test it till you hit a limit, c. Have I finished? If not then d. work out what was the limiting factor, e. go back to step a (rinse and repeat).
Here is an example with 2 million TCP connections onto a beefy box (128GB RAM and 40 cores) running Phoenix http://www.phoenixframework.org/blog/the-road-to-2-million-websocket-connections - they ended up needing 50 or so reasonably significant servers just to provide the client load (their initial smaller clients maxed out to early, eg "maxed our 4core/15gb box @ 450k clients").
Here is another reference for go this time at 10 million: http://goroutines.com/10m.
This appears to be java based and 12 million connections: https://mrotaru.wordpress.com/2013/06/20/12-million-concurrent-connections-with-migratorydata-websocket-server/
basically set.seed() function will help to reuse the same set of random variables , which we may need in future to again evaluate particular task again with same random varibales
we just need to declare it before using any random numbers generating function.
This could also be an issue of port 80 being used by "Web Deployment Agent Service". you can stop it from administrative tools->services and free up that port. as shown here
As others indicated you can use dynamic_cast. But generally using dynamic_cast for finding out the type of the derived class you are working upon indicates the bad design. If you are overriding a function that takes pointer of A as the parameter then it should be able to work with the methods/data of class A itself and should not depend on the the data of class B. In your case instead of overriding if you are sure that the method you are writing will work with only class B, then you should write a new method in class B.
The simplest solution (without depending on any third-party library or platform) is to create a URL instance pointing to the web page / link you want to download, and read the content using streams.
For example:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class DownloadPage {
public static void main(String[] args) throws IOException {
// Make a URL to the web page
URL url = new URL("http://stackoverflow.com/questions/6159118/using-java-to-pull-data-from-a-webpage");
// Get the input stream through URL Connection
URLConnection con = url.openConnection();
InputStream is =con.getInputStream();
// Once you have the Input Stream, it's just plain old Java IO stuff.
// For this case, since you are interested in getting plain-text web page
// I'll use a reader and output the text content to System.out.
// For binary content, it's better to directly read the bytes from stream and write
// to the target file.
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line = null;
// read each line and write to System.out
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
Hope this helps.
I encounter a strange condition.
self.viewControllers.first
is not root viewController always.
Generally, self.viewControllers.first
is root viewController indeed. But sometimes it's not.
class MyCustomMainNavigationController: UINavigationController {
function configureForView(_ v: UIViewController, animated: Bool) {
let root = self.viewControllers.first
let isRoot = (v == root)
// Update UI based on isRoot
// ....
}
}
extension MyCustomMainNavigationController: UINavigationControllerDelegate {
func navigationController(_ navigationController: UINavigationController,
willShow viewController: UIViewController,
animated: Bool) {
self.configureForView(viewController, animated: animated)
}
}
Generally, self.viewControllers.first
is root
viewController.
But, when I call popToRootViewController(animated:)
, and then it triggers navigationController(_:willShow:animated:)
. At this moment, self.viewControllers.first
is NOT root viewController, it's the last viewController which will disappear.
self.viewControllers.first
is not always root
viewController. Sometime, it will be the last viewController.So, I suggest to keep rootViewController
by property when self.viewControllers
have ONLY one viewController. I get root viewController in viewDidLoad()
of custom UINavigationController.
class MyCustomMainNavigationController: UINavigationController {
fileprivate var myRoot: UIViewController!
override func viewDidLoad() {
super.viewDidLoad()
// My UINavigationController is defined in storyboard.
// So at this moment,
// I can get root viewController by `self.topViewController!`
let v = self.topViewController!
self.myRoot = v
}
}

You can use fstat() to get the file's inode by struct stat. Then, using readdir() you can compare the inode you found with those that exist (struct dirent) in a directory (assuming that you know the directory, otherwise you'll have to search the whole filesystem) and find the corresponding file name. Nasty?
It is worth noting that despite the fact that you can SELECT INTO
global variables like:
SELECT ... INTO @XYZ ...
You can NOT use FETCH INTO
global variables like:
FETCH ... INTO @XYZ
Looks like it's not a bug. I hope it will be helpful to someone...
Instead of using HTML entities like
and  
(as others have suggested), you can use the Unicode em space (8195 in UTF-8) directly. Try copy-pasting the following into your README.md
. The spaces at the start of the lines are em spaces.
The action of every agent <br />

Ok, this should be really easy:
$ sudo vi /etc/subversion/servers
Edit the file:
[Global]
http-proxy-host=my.proxy.com
http-proxy-port=3128
Save it, run svn
again and it will work.
Use mysqli_fetch_row()
. Try this,
$query = "SELECT ssfullname, ssemail FROM userss WHERE user_id = ".$user_id;
$result = mysqli_query($conn, $query);
$row = mysqli_fetch_row($result);
$ssfullname = $row['ssfullname'];
$ssemail = $row['ssemail'];
You can do it this way. It needs to go in the maven format:
repositories {
maven { url uri('folderName')}
}
And then your AAR needs to go in a folder structure for a group id "com.example":
folderName/
com/
example/
verion/
myaar-version.aar
Then reference as a dependency:
compile 'com.example:myaar:version@aar'
Where version
is the version of your aar file (ie, 3.0, etc)
Important: Use the
( )
parentheses in your search string
While the previous answer is correct there is an important thing to emphasize! All the matched segments in your search string that you want to use in your replacement string must be enclosed by ( )
parentheses, otherwise these matched segments won't be accessible to defined variables such as $1
, $2
or \1
, \2
etc.
For example we want to replace 'em' with 'px' but preserve the digit values:
margin: 10em; /* Expected: margin: 10px */
margin: 2em; /* Expected: margin: 2px */
margin: $1px
or margin: \1px
margin: ([0-9]*)em
// with parenthesesmargin: [0-9]*em
CORRECT CASE EXAMPLE: Using margin: ([0-9]*)em
search string (with parentheses). Enclose the desired matched segment (e.g. $1
or \1
) by ( )
parentheses as following:
margin: ([0-9]*)em
(with parentheses)margin: $1px
or margin: \1px
margin: 10px;
margin: 2px;
INCORRECT CASE EXAMPLE: Using margin: [0-9]*em
search string (without parentheses). The following regex pattern will match the desired lines but matched segments will not be available in replaced string as variables such as $1
or \1
:
margin: [0-9]*em
(without parentheses)margin: $1px
or margin: \1px
margin: px; /* `$1` is undefined */
margin: px; /* `$1` is undefined */
You need to set the password for root@localhost
to be blank. There are two ways:
The MySQL SET PASSWORD
command:
SET PASSWORD FOR root@localhost=PASSWORD('');
Using the command-line mysqladmin
tool:
mysqladmin -u root -pCURRENTPASSWORD password ''
>>> a = '&#'
>>> print a.replace('&', r'\&')
\&#
>>> print a.replace('#', r'\#')
&\#
>>>
You want to use a 'raw' string (denoted by the 'r' prefixing the replacement string), since raw strings to not treat the backslash specially.
I had the same problem. My solution was to make all vectors numeric.
you have to use the To_Date() function to convert the string to date ! http://www.techonthenet.com/oracle/functions/to_date.php
You can try with Directory.GetFiles and fix your pattern
string[] files = Directory.GetFiles(@"c:\", "*.txt");
foreach (string file in files)
{
File.Copy(file, "....");
}
Or Move
foreach (string file in files)
{
File.Move(file, "....");
}
You don't have access to the right image as far my knowledge, unless you override the onTouch
event. I suggest to use a RelativeLayout
, with one editText
and one imageView
, and set OnClickListener
over the image view as below:
<RelativeLayout
android:id="@+id/rlSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:drawable/edit_text"
android:padding="5dip" >
<EditText
android:id="@+id/txtSearch"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="@+id/imgSearch"
android:background="#00000000"
android:ems="10"/>
<ImageView
android:id="@+id/imgSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="@drawable/btnsearch" />
</RelativeLayout>
In addition to running
php -m
to get the list of installed php modules, you will probably find it helpful to get the list of the currently installed php packages in Ubuntu:
sudo dpkg --get-selections | grep -v deinstall | grep php
This is helpful since Ubuntu makes php modules available via packages.
You can then install the needed modules by selecting from the available Ubuntu php packages, which you can view by running:
sudo apt-cache search php | grep "^php5-"
Or, for Ubuntu 16.04 and higher:
sudo apt-cache search php | grep "^php7"
As you have mentioned, there is plenty of information available on the actual installation of the packages that you might require, so I won't go into detail about that here.
It is possible that an installed module has been disabled. In that case, it won't show up when running php -m
, but it will show up in the list of installed Ubuntu packages.
Modules can be enabled/disabled via the php5enmod
tool (phpenmod
on later distros) which is part of the php-common
package.
Ubuntu 12.04:
Enabled modules are symlinked in /etc/php5/conf.d
Ubuntu 12.04: (with PHP 5.4+)
To enable an installed module:
php5enmod <modulename>
To disable an installed module:
php5dismod <modulename>
Ubuntu 16.04 (php7) and higher:
To enable an installed module:
phpenmod <modulename>
To disable an installed module:
phpdismod <modulename>
Reload Apache
Remember to reload Apache2 after enabling/disabling:
service apache2 reload
var x = y !== undefined ? y : 1;
Note that var x = y || 1;
would assign 1
for any case where y
is falsy (e.g. false
, 0
, ""
), which may be why it "didn't work" for you. Also, if y
is a global variable, if it's truly not defined you may run into an error unless you access it as window.y
.
As vol7ron suggests in the comments, you can also use typeof
to avoid the need to refer to global vars as window.<name>
:
var x = typeof y != "undefined" ? y : 1;
viewport
meta tag on mobile browser,
The initial-scale property controls the zoom level when the page is first loaded. The maximum-scale, minimum-scale, and user-scalable properties control how users are allowed to zoom the page in or out.
The primary difference is, @Autowired
is a spring annotation. Whereas @Resource
is specified by the JSR-250, as you pointed out yourself. So the latter is part of Java whereas the former is Spring specific.
Hence, you are right in suggesting that, in a sense. I found folks use @Autowired
with @Qualifier
because it is more powerful. Moving from some framework to some other is considered very unlikely, if not myth, especially in the case of Spring.

And run it via Excel macro menu like suggested from "user3616725" from accepted answer:
Back in Excel, go Tools>Macro>Macros and select the macro called "CopyCellContents" and then choose Options from the dialog. Here you can assign the macro to a shortcut key (eg like Ctrl+c for normal copy) - I used Ctrl+q.
Then, when you want to copy a single cell over to Notepad/wherever, just do Ctrl+q (or whatever you chose) and then do a Ctrl+v or Edit>Paste in your chosen destination.
Edit (21st of November in 2015):
@ comment from "dotctor":
No, this seriously is no new question! In my opinion it is a good addition for the accepted answer as my answer addresses problems that you can face when using the code from the accepted answer. If I would have more reputation, I would have created a comment.
@ comment from "Teepeemm":
Yes, you are right, answers beginning with title "Problem:" are misleading. Changed to: "Possible problem in relation to answer from "user3616725":". As a comment I certainly would have written much more compact.
<pre>
<input type="text" #titleInput>
<button type="submit" (click) = 'addTodo(titleInput.value)'>Add</button>

If you want to use glyph icons with bootstrap 2.3.2, Add the font files from bootstrap 3 to your project folder then copy this to your css file
@font-face {
font-family: 'Glyphicons Halflings';
src: url('../fonts/glyphicons-halflings-regular.eot');
src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
Several ways to accomplish that but be aware that your DB date_format option & date_order option settings could affect the incoming format:
Select
cast('2008-09-16' as date)
convert(date,'16/09/2008',103)
date('2008-09-16')
from dummy;
You can use a separate class to represent the JSON object and use @SerializedName
annotations to specify the field name to grab for each data member:
public class Response {
@SerializedName("data")
private Data data;
private static class Data {
@SerializedName("translations")
public Translation[] translations;
}
private static class Translation {
@SerializedName("translatedText")
public String translatedText;
}
public String getTranslatedText() {
return data.translations[0].translatedText;
}
}
Then you can do the parsing in your parse() method using a Gson
object:
Gson gson = new Gson();
Response response = gson.fromJson(jsonLine, Response.class);
System.out.println("Translated text: " + response.getTranslatedText());
With this approach, you can reuse the Response
class to add any other additional fields to pick up other data members you might want to extract from JSON -- in case you want to make changes to get results for, say, multiple translations in one call, or to get an additional string for the detected source language.
Not sure about older versions, but in 2016.2 removing the .key
file(s) didn't work for me.

You'll have to do 2 things to make a Bootstrap label (or anything really) adjust sizes based on screen size:
.label { font-size: 75% }
. So any extra selector on your CSS rule will make it more specific.Here's an example CSS listing to accomplish what you are asking, using the default 4 sizes in Bootstrap:
@media (max-width: 767) {
/* your custom css class on a parent will increase specificity */
/* so this rule will override Bootstrap's font size setting */
.autosized .label { font-size: 14px; }
}
@media (min-width: 768px) and (max-width: 991px) {
.autosized .label { font-size: 16px; }
}
@media (min-width: 992px) and (max-width: 1199px) {
.autosized .label { font-size: 18px; }
}
@media (min-width: 1200px) {
.autosized .label { font-size: 20px; }
}
Here is how it could be used in the HTML:
<!-- any ancestor could be set to autosized -->
<div class="autosized">
...
...
<span class="label label-primary">Label 1</span>
</div>
In your example propertyInfo.GetValue(this, null)
should work. Consider altering GetNamesAndTypesAndValues()
as follows:
public void GetNamesAndTypesAndValues()
{
foreach (PropertyInfo propertyInfo in allClassProperties)
{
Console.WriteLine("{0} [type = {1}] [value = {2}]",
propertyInfo.Name,
propertyInfo.PropertyType,
propertyInfo.GetValue(this, null));
}
}
To "fwd declare a typedef" you need to fwd declare a class or a struct and then you can typedef declared type. Multiple identical typedefs are acceptable by compiler.

To create a new branch by branching off from an existing branch
git checkout -b <new_branch>
and then push this new branch to repository using
git push -u origin <new_branch>
This creates and pushes all local commits to a newly created remote branch origin/<new_branch>
For windows 8.1 & python 2.7 , I fixed the problem by following below steps
1 . Download and install graphviz-2.38.msi https://graphviz.gitlab.io/_pages/Download/Download_windows.html
2 . Set the path variable
Control Panel > System and Security > System > Advanced System Settings > Environment Variables > Path > Edit add 'C:\Program Files (x86)\Graphviz2.38\bin'
instanceof
in Javascript can be flaky - I believe major frameworks try to avoid its use. Different windows is one of the ways in which it can break - I believe class hierarchies can confuse it as well.
There are better ways for testing whether an object is a certain built-in type (which is usually what you want). Create utility functions and use them:
function isFunction(obj) {
return typeof(obj) == "function";
}
function isArray(obj) {
return typeof(obj) == "object"
&& typeof(obj.length) == "number"
&& isFunction(obj.push);
}
And so on.
You don't need pip
for installing Beautiful Soup - you can just download it and run python setup.py install
from the directory that you have unzipped BeautifulSoup in (assuming that you have added Python to your system PATH
- if you haven't and you don't want to you can run C:\Path\To\Python27\python "C:\Path\To\BeautifulSoup\setup.py" install
)
However, you really should install pip
- see How to install pip on Windows for how to do that best (via @MartijnPieters comment)
From PHP 7.1 you can do this (Accepted rfc for negative string offsets):
<?php
$silly = 'Mary had a little lamb';
echo $silly[-20];
echo $silly{-6};
echo $silly[-3];
echo $silly[-15];
echo $silly[-13];
echo $silly[-1];
echo $silly[-4];
echo $silly{-10};
echo $silly[-4];
echo $silly[-8];
echo $silly{3}; // <-- this will be deprecated in PHP 7.4
die();
I'll let you guess the output.
Also, I added this to xenonite's performance code with these results:
substr() took 7.0334868431091seconds
array access took 2.3111131191254seconds
Direct string access (negative string offsets) took 1.7971360683441seconds
The delegates:
function displayMessage(message, f)
{
f(message); // execute function "f" with variable "message"
}
function alerter(message)
{
alert(message);
}
function writer(message)
{
document.write(message);
}
Running the displayMessage function:
function runDelegate()
{
displayMessage("Hello World!", alerter); // alert message
displayMessage("Hello World!", writer); // write message to DOM
}
This worked for me
<Text>{`Hi~\nthis is a test message.`}</Text>

I urge you to read this blog post that directly addresses your problem.
Using custom model binders isn't really wise as Phil Haack pointed out (his blog post is linked in the upper blog post as well).
Basically you have three options:
Write a JsonValueProviderFactory
and use a client side library like json2.js
to communicate wit JSON directly.
Write a JQueryValueProviderFactory
that understands the jQuery JSON object transformation that happens in $.ajax
or
Use the very simple and quick jQuery plugin outlined in the blog post, that prepares any JSON object (even arrays that will be bound to IList<T>
and dates that will correctly parse on the server side as DateTime
instances) that will be understood by Asp.net MVC default model binder.
Of all three, the last one is the simplest and doesn't interfere with Asp.net MVC inner workings thus lowering possible bug surface. Using this technique outlined in the blog post will correctly data bind your strong type action parameters and validate them as well. So it is basically a win win situation.
As you're using C++ you could use std::string
.
Use $dirty
flag to show the error only after user interacted with the input:
<div>
<input type="email" name="email" ng-model="user.email" required />
<span ng-show="form.email.$dirty && form.email.$error.required">Email is required</span>
</div>
If you want to trigger the errors only after the user has submitted the form than you may use a separate flag variable as in:
<form ng-submit="submit()" name="form" ng-controller="MyCtrl">
<div>
<input type="email" name="email" ng-model="user.email" required />
<span ng-show="(form.email.$dirty || submitted) && form.email.$error.required">
Email is required
</span>
</div>
<div>
<button type="submit">Submit</button>
</div>
</form>
function MyCtrl($scope){
$scope.submit = function(){
// Set the 'submitted' flag to true
$scope.submitted = true;
// Send the form to server
// $http.post ...
}
};
Then, if all that JS inside ng-show
expression looks too much for you, you can abstract it into a separate method:
function MyCtrl($scope){
$scope.submit = function(){
// Set the 'submitted' flag to true
$scope.submitted = true;
// Send the form to server
// $http.post ...
}
$scope.hasError = function(field, validation){
if(validation){
return ($scope.form[field].$dirty && $scope.form[field].$error[validation]) || ($scope.submitted && $scope.form[field].$error[validation]);
}
return ($scope.form[field].$dirty && $scope.form[field].$invalid) || ($scope.submitted && $scope.form[field].$invalid);
};
};
<form ng-submit="submit()" name="form">
<div>
<input type="email" name="email" ng-model="user.email" required />
<span ng-show="hasError('email', 'required')">required</span>
</div>
<div>
<button type="submit">Submit</button>
</div>
</form>
For 1. topic (Target Unreachable, identifier 'bean' resolved to null);
I checked valuable answers the @BalusC and the other sharers but I exceed the this problem like this on my scenario. After the creating a new xhtml with different name and creating bean class with different name then I wrote (not copy-paste) the codes step by step to the new bean class and new xhtml file.
You will need to use semicolon as delimiter while specifying the jar and class file path in windows. This solved the issue.
Assuming the class file is under C:.
java -cp ".;C:\testng.jar" org.testng.TestNG testing.xml
Definitely compact
is the best approach for solving this task. However, we can achieve the same result just with a simple subtraction:
[1, nil, 3, nil, nil] - [nil]
=> [1, 3]
Usually this happens if something is wrong with the byte array.
File.WriteAllBytes("filename.PDF", Byte[]);
This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.
Asynchronous implementation of this is also available.
public static System.Threading.Tasks.Task WriteAllBytesAsync
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);
Use nolock when you are okay with the "dirty" data. Which means nolock can also read data which is in the process of being modified and/or uncommitted data.
It's generally not a good idea to use it in high transaction environment and that is why it is not a default option on query.
Lets take an example where you want to print numbers from 0 to n in the same line. You can do this with the help of following code.
n=int(raw_input())
i=0
while(i<n):
print i,
i = i+1
At input, n = 5
Output : 0 1 2 3 4
You can also solve this problem via Apache configuration using mod_remoteip, by adding the following to a conf.d file:
RemoteIPHeader X-Forwarded-For
RemoteIPInternalProxy 172.16.0.0/12
LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
Have a look at PHP's available XML extensions.
The main difference between XML Parser and SimpleXML is that the latter is not a pull parser. SimpleXML is built on top of the DOM extensions and will load the entire XML file into memory. XML Parser like XMLReader will only load the current node into memory. You define handlers for specific nodes which will get triggered when the Parser encounters it. That is faster and saves on memory. You pay for that with not being able to use XPath.
Personally, I find SimpleXml quite limiting (hence simple) in what it offers over DOM. You can switch between DOM and SimpleXml easily though, but I usually dont bother and go the DOM route directly. DOM is an implementation of the W3C DOM API, so you might be familiar with it from other languages, for instance JavaScript.
Here is an alternative way:
select * from tbl where col like 'ABC%'
union
select * from tbl where col like 'XYZ%'
union
select * from tbl where col like 'PQR%';
Here is the test code to verify:
create table tbl (col varchar(255));
insert into tbl (col) values ('ABCDEFG'), ('HIJKLMNO'), ('PQRSTUVW'), ('XYZ');
select * from tbl where col like 'ABC%'
union
select * from tbl where col like 'XYZ%'
union
select * from tbl where col like 'PQR%';
+----------+
| col |
+----------+
| ABCDEFG |
| XYZ |
| PQRSTUVW |
+----------+
3 rows in set (0.00 sec)
Well if you using Java 8 or older version Here is the Best solution.
Collections.sort(studentList, Comparator.comparing(Student::getCgpa).reversed().thenComparing(Student:: getFname).thenComparing(Student::getId));
In this case, it will first sort with 'getCgpa' first and for the second part it will sort with getFname and getId. Which is field into the pojo class.
Maybe git mv
has changed since these answers were posted, so I will update briefly. In my view, git mv
is not accurately described as short hand for:
# not accurate: #
mv oldname newname
git add newname
git rm oldname
I use git mv frequently for two reasons that have not been described in previous answers:
Moving large directory structures, where I have mixed content of both tracked and untracked files. Both tracked and untracked files will move, and retain their tracking/untracking status
Moving files and directories that are large, I have always assumed that git mv
will reduce the size of the repository DB history size. This is because moving/renaming a file is indexation/reference delta. I have not verified this assumption, but it seems logical.
var apps = [{id:34,name:'My App',another:'thing'},{id:37,name:'My New App',another:'things'}];
// get index of object with id:37
var removeIndex = apps.map(function(item) { return item.id; }).indexOf(37);
// remove object
apps.splice(removeIndex, 1);
You should not create an instance of the activity class. It is wrong. Activity has ui and lifecycle and activity is started by startActivity(intent)
You can use startActivityForResult
or you can pass the values from one activity to another using intents and do what is required. But it depends on what you intend to do in the method.
A simple and flexible offline recognition on Android is implemented by CMUSphinx, an open source speech recognition toolkit. It works purely offline, fast and configurable It can listen continuously for keyword, for example.
You can find latest code and tutorial here.
Update in 2019: Time goes fast, CMUSphinx is not that accurate anymore. I recommend to try Kaldi toolkit instead. The demo is here.
You should generally prefer a return value over an out param. Out params are a necessary evil if you find yourself writing code that needs to do 2 things. A good example of this is the Try pattern (such as Int32.TryParse).
Let's consider what the caller of your two methods would have to do. For the first example I can write this...
int foo = GetValue();
Notice that I can declare a variable and assign it via your method in one line. FOr the 2nd example it looks like this...
int foo;
GetValue(out foo);
I'm now forced to declare my variable up front and write my code over two lines.
update
A good place to look when asking these types of question is the .NET Framework Design Guidelines. If you have the book version then you can see the annotations by Anders Hejlsberg and others on this subject (page 184-185) but the online version is here...
http://msdn.microsoft.com/en-us/library/ms182131(VS.80).aspx
If you find yourself needing to return two things from an API then wrapping them up in a struct/class would be better than an out param.
UPD. Check the comment before. It isn't exactly what was asked.
If you are using apache.commons
you may copy streams using IOUtils
.
You can use following code:
InputStream = IOUtils.toBufferedInputStream(toCopy);
Here is the full example suitable for your situation:
public void cloneStream() throws IOException{
InputStream toCopy=IOUtils.toInputStream("aaa");
InputStream dest= null;
dest=IOUtils.toBufferedInputStream(toCopy);
toCopy.close();
String result = new String(IOUtils.toByteArray(dest));
System.out.println(result);
}
This code requires some dependencies:
MAVEN
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
GRADLE
'commons-io:commons-io:2.4'
Here is the DOC reference for this method:
Fetches entire contents of an InputStream and represent same data as result InputStream. This method is useful where,
Source InputStream is slow. It has network resources associated, so we cannot keep it open for long time. It has network timeout associated.
You can find more about IOUtils
here:
http://commons.apache.org/proper/commons-io/javadocs/api-2.4/org/apache/commons/io/IOUtils.html#toBufferedInputStream(java.io.InputStream)
There's a simple solution, that at least for me, is the only feasible solution.
The problem is that all the answers I see being tossed around - using Joda, or Calendar, or Date, or whatever - only take the amount of milliseconds into consideration. They end up counting the number of 24-hour cycles between two dates, rather than the actual number of days. So something from Jan 1st 11pm to Jan 2nd 1am will return 0 days.
To count the actual number of days between startDate
and endDate
, simply do:
// Find the sequential day from a date, essentially resetting time to start of the day
long startDay = startDate.getTime() / 1000 / 60 / 60 / 24;
long endDay = endDate.getTime() / 1000 / 60 / 60 / 24;
// Find the difference, duh
long daysBetween = endDay - startDay;
This will return "1" between Jan 2nd and Jan 1st. If you need to count the end day, just add 1 to daysBetween
(I needed to do that in my code since I wanted to count the total number of days in the range).
This is somewhat similar to what Daniel has suggested but smaller code I suppose.
That depends on what type your list is, for ArrayList
use:
list.get(0);
for LinkedList
use:
list.getFirst();
if you like the array
approach:
list.toArray()[0];
When you first render your component, this.state.name
isn't set, so it evaluates to undefined
or null
, and you end up passing value={undefined}
or value={null}
to your input
.
When ReactDOM checks to see if a field is controlled, it checks to see if value != null
(note that it's !=
, not !==
), and since undefined == null
in JavaScript, it decides that it's uncontrolled.
So, when onFieldChange()
is called, this.state.name
is set to a string value, your input goes from being uncontrolled to being controlled.
If you do this.state = {name: ''}
in your constructor, because '' != null
, your input will have a value the whole time, and that message will go away.

jQuery Feeds is a nice option, it has a built-in templating system and uses the Google Feed API, so it has cross-domain support.
Have a look into the start

the tutorial of how to build NodeJS for Android https://github.com/dna2github/dna2oslab/tree/master/android/build
there are several versions v0.12, v4, v6, v7
It is easy to run compiled binary on Android; for example run compiled Nginx: https://github.com/dna2github/dna2mtgol/tree/master/fileShare
You just need to modify code to replace Nginx to NodeJS; it is better if using Android Service to run node js server on the backend.
OffsetDateTime.parse ( "2010-01-01T12:00:00+01:00" )
The new java.time package in Java 8 and later was inspired by Joda-Time.
The OffsetDateTime
class represents a moment on the timeline with an offset-from-UTC but not a time zone.
OffsetDateTime odt = OffsetDateTime.parse ( "2010-01-01T12:00:00+01:00" );
Calling toString
generates a string in standard ISO 8601 format:
2010-01-01T12:00+01:00
To see the same value through the lens of UTC, extract an Instant
or adjust the offset from +01:00
to 00:00
.
Instant instant = odt.toInstant();
…or…
OffsetDateTime odtUtc = odt.withOffsetSameInstant( ZoneOffset.UTC );
Adjust into a time zone if desired. A time zone is a history of offset-from-UTC values for a region, with a set of rules for handling anomalies such as Daylight Saving Time (DST). So apply a time zone rather than a mere offset whenever possible.
ZonedDateTime zonedDateTimeMontréal = odt.atZoneSameInstant( ZoneId.of( "America/Montreal" ) );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek

First of all you have to include your font in your website (or your CSS, to be more specific) using an appropriate @font-face
rule.
From here on there are multiple ways to proceed. One thing I would not do is to edit the bootstrap.css directly - since once you get a newer version your changes will be lost. You do however have the possibility to customize your bootstrap files (there's a customize page on their website). Just enter the name of your font with all the fallback names into the corresponding typography textbox. Of course you will have to do this whenever you get a new or updated version of your bootstrap files.
Another chance you have is to overwrite the bootstrap rules within a different stylesheet. If you do this you just have to use selectors that are as specific as (or more specific than) the bootstrap selectors.
Side note: If you care about browser support a single EOT version of your font might not be sufficient. See http://caniuse.com/eot for a support table.
A ready function based on top rated answer:
/**
* Check if date exists and is valid.
*
* @param {String} dateString Date in YYYY-mm-dd format.
*/
function isValidDate(dateString) {
var isValid = false;
var date;
date =
new Date(
dateString);
if (
Object.prototype.toString.call(
date) === "[object Date]") {
if (isNaN(date.getTime())) {
// Date is unreal.
} else {
// Date is real if month and day match each other in date and string (otherwise may be shifted):
isValid =
date.getUTCMonth() + 1 === dateString.split("-")[1] * 1 &&
date.getUTCDate() === dateString.split("-")[2] * 1;
}
} else {
// It's not a date.
}
return isValid;
}
In your giant elif
chain, you skipped 13. You might want to throw an error if you hit the end of the chain without returning anything, to catch numbers you missed and incorrect calls of the function:
...
elif x == 90:
return 6
else:
raise ValueError(x)
A Bin file is a pure binary file with no memory fix-ups or relocations, more than likely it has explicit instructions to be loaded at a specific memory address. Whereas....
ELF files are Executable Linkable Format which consists of a symbol look-ups and relocatable table, that is, it can be loaded at any memory address by the kernel and automatically, all symbols used, are adjusted to the offset from that memory address where it was loaded into. Usually ELF files have a number of sections, such as 'data', 'text', 'bss', to name but a few...it is within those sections where the run-time can calculate where to adjust the symbol's memory references dynamically at run-time.
Though the environment variable JAVA_HOME
set correctly, the ant
may use the configured JRE within the each build.xml or any build files.
To check what version of the JRE the ant is using, right click on the build file -> select the build ant which displays the details about the tasks to choose etc, select the JRE which you want to use.
Its advisable to use the project level settings or just at the workspace level.
Another great implementation is balupton's jQuery History which will use the native onhashchange event if it is supported by the browser, if not it will use an iframe or interval appropriately for the browser to ensure all the expected functionality is successfully emulated. It also provides a nice interface to bind to certain states.
Another project worth noting as well is jQuery Ajaxy which is pretty much an extension for jQuery History to add ajax to the mix. As when you start using ajax with hashes it get's quite complicated!
To reduce memory consumption and to speed up the search you may use -ReadCount option of Get-Content cmdlet (https://technet.microsoft.com/ru-ru/library/hh849787.aspx).
This may save hours when you working with large files.
Here is an example:
$n = 60699010
$src = 'hugefile.csv'
$batch = 100
$timer = [Diagnostics.Stopwatch]::StartNew()
$count = 0
Get-Content $src -ReadCount $batch -TotalCount $n | % {
$count += $_.Length
if ($count -ge $n ) {
$_[($n - $count + $_.Length - 1)]
}
}
$timer.Stop()
$timer.Elapsed
This prints $n'th line and elapsed time.
That is allowed by default on MySQL.
What is disabled by default is remote root
access. If you want to enable that, run this SQL command locally:
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
And then find the following line and comment it out in your my.cnf
file, which usually lives on /etc/mysql/my.cnf
on Unix/OSX systems. In some cases the location for the file is /etc/mysql/mysql.conf.d/mysqld.cnf).
If it's a Windows system, you can find it in the MySQL installation directory, usually something like C:\Program Files\MySQL\MySQL Server 5.5\
and the filename will be my.ini
.
Change line
bind-address = 127.0.0.1
to
#bind-address = 127.0.0.1
And restart the MySQL server (Unix/OSX, and Windows) for the changes to take effect.
It may not be quite what you want, since it's not a standard command on anyone's systems, but since my program should work fine on POSIX systems (if compiled), I'll mention it anyway. If you have the ability to compile or add programs on the machine in question, it should work.
I've used it without issue for about a year now, but it could be that it won't handle some edge cases. Most specifically, I have no idea what it would do with newlines in strings; a case for \\n
might need to be added. This list of characters is not authoritative, but I believe it covers everything else.
I wrote this specifically as a 'helper' program so I could make a wrapper for things like scp
commands.
It can likely be implemented as a shell function as well
I therefore present escapify.c
. I use it like so:
scp user@host:"$(escapify "/this/path/needs to be escaped/file.c")" destination_file.c
PLEASE NOTE: I made this program for my own personal use. It also will (probably wrongly) assume that if it is given more than one argument that it should just print an unescaped space and continue on. This means that it can be used to pass multiple escaped arguments correctly, but could be seen as unwanted behavior by some.
#include <stdio.h>
#include <string.h>

if(argc < 2)
{
return 0;
}
while(j<argc)

c=argv[j][i];

It's the resources required to set up an operation. It might seem unrelated, but necessary.
It's like when you need to go somewhere, you might need a car. But, it would be a lot of overhead to get a car to drive down the street, so you might want to walk. However, the overhead would be worth it if you were going across the country.
In computer science, sometimes we use cars to go down the street because we don't have a better way, or it's not worth our time to "learn how to walk".
As of now the best way is to use android:fadeScrollbars="false"
in xml which is equivalent to ScrollView.setScrollbarFadingEnabled(false);
in java code.
It is called the extended call syntax. From the documentation:
If the syntax *expression appears in the function call, expression must evaluate to a sequence. Elements from this sequence are treated as if they were additional positional arguments; if there are positional arguments x1,..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.
and:
If the syntax **expression appears in the function call, expression must evaluate to a mapping, the contents of which are treated as additional keyword arguments. In the case of a keyword appearing in both expression and as an explicit keyword argument, a TypeError exception is raised.
In order to take a picture you have to determine a path where you would like the image saved and pass that as an extra in the intent, for example:
private void capture(){
String directoryPath = Environment.getExternalStorageDirectory() + "/" + IMAGE_DIRECTORY + "/";
String filePath = directoryPath+Long.toHexString(System.currentTimeMillis())+".jpg";
File directory = new File(directoryPath);
if (!directory.exists()) {
directory.mkdirs();
}
this.capturePath = filePath; // you will process the image from this path if the capture goes well
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra( MediaStore.EXTRA_OUTPUT, Uri.fromFile( new File(filePath) ) );
startActivityForResult(intent, REQUEST_CAPTURE);
}
I just copied the above portion from another answer I gave.
However to warn you there are a lot of inconsitencies with image capture behavior between devices that you should look out for.
Here is an issue I ran into on some HTC devices, where it would save in the location I passed and in it's default location resulting in duplicate images on the device: Deleting a gallery image after camera intent photo taken
Make sure that there is no project Deploy in server. If so ,please right click on server ,select add and remove ,Then remove all project. After this you can double click on server and the option will be enabled for you.
You can use the grid
feature for the second unused axis x2
, which is the most natural way of drawing a set of regular spaced lines.
set grid x2tics
set x2tics 10 format "" scale 0
In general, the grid is drawn at the same position as the tics on the axis. In case the position of the lines does not correspond to the tics position, gnuplot provides an additional set of tics, called x2tics
. format ""
and scale 0
hides the x2tics so you only see the grid lines.
You can style the lines as usual with linewith
, linecolor
.
Here's some code I use with sys.version_info
to check the Python installation:
def check_installation(rv):
current_version = sys.version_info
if current_version[0] == rv[0] and current_version[1] >= rv[1]:
pass
else:
sys.stderr.write( "[%s] - Error: Your Python interpreter must be %d.%d or greater (within major version %d)\n" % (sys.argv[0], rv[0], rv[1], rv[0]) )
sys.exit(-1)
return 0
...
# Calling the 'check_installation' function checks if Python is >= 2.7 and < 3
required_version = (2,7)
check_installation(required_version)
You can return the state this way:
$state.go($state.$current.parent.self.name, $state.params);
An example:
(function() {
'use strict'
angular.module('app')
.run(Run);
/* @ngInject */
function Run($rootScope, $state) {
$rootScope.back = function() {
$state.go($state.$current.parent.self.name, $state.params);
};
};
})();
Is it possible to add onclick to a div and have it occur if any area of the div is clicked.
Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work
If yes then why is the onclick method not going through to my div.
You are assigning a string where a function is expected.
divTag.onclick = printWorking;
There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.
That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener
1, 2, 3 ,... are invalid identifiers in python because first of all they are integer objects and secondly in python a variable name can't start with a number.
>>> 1 = 12 #you can't assign to an integer
File "<ipython-input-177-30a62b7248f1>", line 1
SyntaxError: can't assign to literal
>>> 1a = 12 #1a is an invalid variable name
File "<ipython-input-176-f818ca46b7dc>", line 1
1a = 12
^
SyntaxError: invalid syntax
Valid identifier definition:
identifier ::= (letter|"_") (letter | digit | "_")*
letter ::= lowercase | uppercase
lowercase ::= "a"..."z"
uppercase ::= "A"..."Z"
digit ::= "0"..."9"
Case C) is the fastest. Having this as an extension:
Public Module MyExtensions
<Extension()> _
Public Sub Add(Of T)(ByRef arr As T(), item As T)
Array.Resize(arr, arr.Length + 1)
arr(arr.Length - 1) = item
End Sub
End Module
Usage:
Dim arr As Integer() = {1, 2, 3}
Dim newItem As Integer = 4
arr.Add(newItem)
' --> duration for adding 100.000 items: 1 msec
' --> duration for adding 100.000.000 items: 1168 msec
Pressing Ctrl+K+C or Ctrl+E+C After selecting the lines you want to comment will not give space after slashes. you can use multiline select to provide space as suggested by Habib
Perhaps, you can use /* before the lines you want to comment and after */ in that case you might not need to provide spaces.
/*
First Line to Comment
Second Line to Comment
Third Line to Comment

To follow up on that the new command from @jimbojw to create a shortcut with the new Xcode (installing through preferences) is:
ln -s /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app /Applications/iPhone\ Simulator.app

You can also use below code which helps me:
select convert(numeric(10,2), column_name) as Total from TABLE_NAME
where Total
is alias of the field you want.
This is the perfect kind of field to define as CHAR 36, by the way, not VARCHAR 36, since each value will have the exact same length. And you'll use less storage space, since you don't need to store the data length for each value, just the value.
I believe this would work for any kind of application:
AppDomain.CurrentDomain.RelativeSearchPath ?? AppDomain.CurrentDomain.BaseDirectory
You can use .empty()
, like this:
$("#foo").empty();
Remove all child nodes of the set of matched elements from the DOM.
Go to enterprise manager, design table, click on your field.
Make a decimal column
In the properties at the bottom there is a precision property
This sentence gets it:
In general, the way to get the best of both worlds is to rebase local changes you’ve made, but haven’t shared yet, before you push them in order to clean up your story, but never rebase anything you’ve pushed somewhere.
For this type error: UnexpectedTypeException ERROR: We are trying to use incorrect Hibernate validator annotation on any bean property. For this same issue for my Springboot project( validating type 'java.lang.Integer')
The solution that worked for me is using @NotNull
for Integer.
Try this?
encodeURIComponent('space word').replace(/%20/g,'+')
Does the following code work for your problem? I've used a foreach with a bit of linq inside to do the combining of lists and assumed that people are equal if their names match, and it seems to print the expected values out when run. Resharper doesn't offer any suggestions to convert the foreach into linq so this is probably as good as it'll get doing it this way.
public class Person
{
public string Name { get; set; }
public int Value { get; set; }
public int Change { get; set; }
public Person(string name, int value)
{
Name = name;
Value = value;
Change = 0;
}
}
class Program
{
static void Main(string[] args)
{
List<Person> list1 = new List<Person>
{
new Person("a", 1),
new Person("b", 2),
new Person("c", 3),
new Person("d", 4)
};
List<Person> list2 = new List<Person>
{
new Person("a", 4),
new Person("b", 5),
new Person("e", 6),
new Person("f", 7)
};
List<Person> list3 = list2.ToList();
foreach (var person in list1)
{
var existingPerson = list3.FirstOrDefault(x => x.Name == person.Name);
if (existingPerson != null)
{
existingPerson.Change = existingPerson.Value - person.Value;
}
else
{
list3.Add(person);
}
}
foreach (var person in list3)
{
Console.WriteLine("{0} {1} {2} ", person.Name,person.Value,person.Change);
}
Console.Read();
}
}
A refinement on the answer by JSmyth:
console.logCopy = console.log.bind(console);
console.log = function()
{
if (arguments.length)
{
var timestamp = new Date().toJSON(); // The easiest way I found to get milliseconds in the timestamp
var args = arguments;
args[0] = timestamp + ' > ' + arguments[0];
this.logCopy.apply(this, args);
}
};
This:
.log
EDIT: Official setuptools dox page:
If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setuptools, but will need to upgrade to the latest version:
On Linux or OS X:
pip install -U pip setuptools
On Windows:
python -m pip install -U pip setuptools
Therefore the rest of this post is probably obsolete (e.g. some links don't work).
Distribute - is a setuptools fork which "offers Python 3 support". Installation instructions for distribute(setuptools) + pip:
curl -O http://python-distribute.org/distribute_setup.py
python distribute_setup.py
easy_install pip
Similar issue here.
UPDATE: Distribute seems to be obsolete, i.e. merged into Setuptools: Distribute is a deprecated fork of the Setuptools project. Since the Setuptools 0.7 release, Setuptools and Distribute have merged and Distribute is no longer being maintained. All ongoing effort should reference the Setuptools project and the Setuptools documentation.
You may try with instructions found on setuptools pypi page (I haven't tested this, sorry :( ):
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python

I went kind of a different route all together, I decided to "De-Nest" them. Maybe someone will find this handy...
var $m1 = $('#Modal1');
var $innermodal = $m1.find(".modal"); //get reference to nested modal
$m1.after($innermodal); // snatch it out of inner modal and put it after.
The classpath in this context is exactly what it is in the general context: anywhere the VM knows it can find classes to be loaded, and resources as well (such as output.vm in your case).
I'd understand Velocity expects to find a file named output.vm anywhere in "no package". This can be a JAR, regular folder, ... The root of any of the locations in the application's classpath.
If the question isn't just "how to access an integer form of the timedelta?" but "how to convert the timedelta column in the dataframe to an int?" the answer might be a little different. In addition to the .dt.days
accessor you need either df.astype
or pd.to_numeric
Either of these options should help:
df['tdColumn'] = pd.to_numeric(df['tdColumn'].dt.days, downcast='integer')
or
df['tdColumn'] = df['tdColumn'].dt.days.astype('int16')
