Yes. You can tell the OS what kind of transition you want to have for your activity.
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().setWindowAnimations(ANIMATION);
...
}
Where ANIMATION is an integer referring to a built in animation in the OS.
You can use JavaScript to do this, with onClick method. This maybe helps CSS3 transition click event
Use overridePendingTransition
startActivity();
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
fadein.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="500" />
</set>
fadeout.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/anticipate_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="500" />
</set>
But you can't do it in the way you may immediately think, because you cant animate or create a transition around the properties you'd otherwise rely on (e.g. display
, or changing dimensions and setting to overflow:hidden
) in order to correctly hide the element and prevent it from taking up visible space.
Therefore, create an animation for the elements in question, and simply toggle visibility:hidden;
after 5 seconds, whilst also setting height and width to zero to prevent the element from still occupying space in the DOM flow.
CSS
html, body {
height:100%;
width:100%;
margin:0;
padding:0;
}
#hideMe {
-moz-animation: cssAnimation 0s ease-in 5s forwards;
/* Firefox */
-webkit-animation: cssAnimation 0s ease-in 5s forwards;
/* Safari and Chrome */
-o-animation: cssAnimation 0s ease-in 5s forwards;
/* Opera */

-webkit-animation-fill-mode: forwards;
animation-fill-mode: forwards;
}
@keyframes cssAnimation {

overflow:hidden;

<div id='hideMe'>Wait for it...</div>
It's not fading to "black transparent" or "white transparent". It's just showing whatever color is "behind" the image, which is not the image's background color - that color is completely hidden by the image.
If you want to fade to black(ish), you'll need a black container around the image. Something like:
.ctr {
margin: 0;
padding: 0;
background-color: black;
display: inline-block;
}
and
<div class="ctr"><img ... /></div>
document.getElementById("myform").submit();
This won't work as your form tag doesn't have an id.
Change it like this and it should work:

You can make it easier in your code (if you're doing this a lot anyway) by using an extension on the DataRow object, like:
static class Extensions
{
public static string GetColumn(this DataRow Row, int Ordinal)
{
return Row.Table.Columns[Ordinal].ColumnName;
}
}
Then call it using:
string MyColumnName = MyRow.GetColumn(5);
origin/xxx
branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).
What you need to do to update the remote is to force push your local changes to master:
git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master
arrayList.set(location,newValue); location= where u wnna insert, newValue= new element you are inserting.

I believe the proper way of adding pthread

is with the following
find_package (Threads REQUIRED)
target_link_libraries(helloworld
${CMAKE_THREAD_LIBS_INIT}
)
Take a look into NSColorWell class reference.
I just wrote this and it looks more clean to me:
const fs = require('fs');
const util = require('util');
const readdir = util.promisify(fs.readdir);
const readFile = util.promisify(fs.readFile);
const readFiles = async dirname => {
try {
const filenames = await readdir(dirname);
console.log({ filenames });
const files_promise = filenames.map(filename => {
return readFile(dirname + filename, 'utf-8');
});
const response = await Promise.all(files_promise);
//console.log({ response })
//return response
return filenames.reduce((accumlater, filename, currentIndex) => {
const content = response[currentIndex];
accumlater[filename] = {
content,
};
return accumlater;
}, {});
} catch (error) {
console.error(error);
}
};
const main = async () => {
const response = await readFiles(
'./folder-name',
);
console.log({ response });
};
_x000D_
You can modify the response
format according to your need.
The response
format from this code will look like:
{
"filename-01":{
"content":"This is the sample content of the file"
},
"filename-02":{
"content":"This is the sample content of the file"
}
}
Why hasn't anyone suggested Activator.CreateInstance
?

This would:
You can consider it equivalent to:
rm -f workdirectory/filename.txt; touch workdirectory/filename.txt
I don't like my switch
statements to fall through - it's far too error prone and hard to read. The only exception is when multiple case
statements all do exactly the same thing.
If there is some common code that multiple branches of a switch statement want to use, I extract that into a separate common function that can be called in any branch.
You can use keyboard short-cut for Description/ detailed information of Table in SQL Server 2008
.
It will show detailed information/ description of mentioned table as,
1) Table created date,
2) Columns Description,
3) Identity,
4) Indexes,
5) Constraints,
6) References etc. As shown Below [example]:
I've forked a CodePen demo that had the same problem with embedding inline SVG into CSS. A solution that works with SCSS is to build a simple url-encoding function.
A string replacement function can be created from the built-in str-slice, str-index functions (see css-tricks, thanks to Hugo Giraudel).
Then, just replace %
,<
,>
,"
,'
, with the
%xx
codes:
@function svg-inline($string){
$result: str-replace($string, "<svg", "<svg xmlns='http://www.w3.org/2000/svg'");
$result: str-replace($result, '%', '%25');
$result: str-replace($result, '"', '%22');
$result: str-replace($result, "'", '%27');
$result: str-replace($result, ' ', '%20');
$result: str-replace($result, '<', '%3C');
$result: str-replace($result, '>', '%3E');
@return "data:image/svg+xml;utf8," + $result;
}
$mySVG: svg-inline("<svg>...</svg>");
html {
height: 100vh;
background: url($mySVG) 50% no-repeat;
}
There is also a image-inline
helper function available in Compass, but since it is not supported in CodePen, this solution might probably be useful.
Demo on CodePen: http://codepen.io/terabaud/details/PZdaJo/
I had similar problem. I r?n npm cache clear
, closed android SDK manager(which was open before) and re-ran npm install -g cordova
and that was enough to solve the problem.
Fetch both the key and the value from the dictionary in the loop:
{% for key, value in mydict.items %}
{{ value }}
{% endfor %}
I find this easier to read and it avoids the need for special coding. I usually need the key and the value inside the loop anyway.
element.is('.class1, .class2')
works, but it's 35% slower than
element.hasClass('class1') || element.hasClass('class2')
If you doubt what i say, you can verify on jsperf.com.
Hope this help someone.

Here is a solution with an stdout redirection:
def elevate():
import ctypes, win32com.shell.shell, win32event, win32process
outpath = r'%s\%s.out' % (os.environ["TEMP"], os.path.basename(__file__))
if ctypes.windll.shell32.IsUserAnAdmin():
if os.path.isfile(outpath):
sys.stderr = sys.stdout = open(outpath, 'w', 0)
return
with open(outpath, 'w+', 0) as outfile:
hProc = win32com.shell.shell.ShellExecuteEx(lpFile=sys.executable, \
lpVerb='runas', lpParameters=' '.join(sys.argv), fMask=64, nShow=0)['hProcess']
while True:
hr = win32event.WaitForSingleObject(hProc, 40)
while True:
line = outfile.readline()
if not line: break
sys.stdout.write(line)
if hr != 0x102: break
os.remove(outpath)
sys.stderr = ''
sys.exit(win32process.GetExitCodeProcess(hProc))
if __name__ == '__main__':
elevate()
main()
Another gotcha for this kind of problem: avoid running pear within a Unix shell (e.g., Git Bash or Cygwin) on a Windows machine. I had the same problem and the path fix suggested above didn't help. Switched over to a Windows shell, and the pear command works as expected.
Log returns are simply the natural log of 1 plus the arithmetic return. So how about this?
df['pct_change'] = df.price.pct_change()
df['log_return'] = np.log(1 + df.pct_change)
Even more concise, utilizing Ximix's suggestion:
df['log_return'] = np.log1p(df.price.pct_change())
Please add try catch also in your code so that you can be sure that there in no exception.
try {
$hostname = "servername";
$dbname = "dbname";
$username = "username";
$pw = "password";
$pdo = new PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");
} catch (PDOException $e) {
echo "Failed to get DB handle: " . $e->getMessage() . "\n";
exit;
}
You should use a keyfile without passphrase for scripted ssh logins. This is obviously a security risk, take care that the keyfile itself is adequately secured.
Your Print method likely needs to wait for the continuation to finish (ContinueWith returns a task which you can wait on). Otherwise the second ReadAsStringAsync finishes, the method returns (before result is assigned in the continuation). Same problem exists in your send method. Both need to wait on the continuation to consistently get the results you want. Similar to below
private static string Send(int id)
{
Task<HttpResponseMessage> responseTask = client.GetAsync("aaaaa");
string result = string.Empty;
Task continuation = responseTask.ContinueWith(x => result = Print(x));
continuation.Wait();
return result;
}
private static string Print(Task<HttpResponseMessage> httpTask)
{
Task<string> task = httpTask.Result.Content.ReadAsStringAsync();
string result = string.Empty;
Task continuation = task.ContinueWith(t =>
{
Console.WriteLine("Result: " + t.Result);
result = t.Result;
});
continuation.Wait();
return result;
}
i think this is simple than other by using [Editable(false)] attribute
for example:
public class MyModel
{
[Editable(false)]
public string userName { get; set; }
}
You can use the Enum.TryParse method:
Age age;
if (Enum.TryParse<Age>("New_Born", out age))
{
// You now have the value in age
}
Use the JQuery Serialize function
http://docs.jquery.com/Ajax/serialize
Serialize is typically used to prepare user input data to be posted to a server. The serialized data is in a standard format that is compatible with almost all server side programming languages and frameworks.
First, gather optimiser stats on the table (if you haven't already):
begin
dbms_stats.gather_table_stats('MYSCHEMA','MYTABLE');
end;
/
WARNING: As Justin says in his answer, gathering optimiser stats affects query optimisation and should not be done without due care and consideration!
Then find the number of blocks occupied by the table from the generated stats:
select blocks, empty_blocks, num_freelist_blocks
from all_tables
where owner = 'MYSCHEMA'
and table_name = 'MYTABLE';
The total number of blocks allocated to the table is blocks + empty_blocks + num_freelist_blocks.
blocks is the number of blocks that actually contain data.
Multiply the number of blocks by the block size in use (usually 8KB) to get the space consumed - e.g. 17 blocks x 8KB = 136KB.
To do this for all tables in a schema at once:
begin
dbms_stats.gather_schema_stats ('MYSCHEMA');
end;
/
select table_name, blocks, empty_blocks, num_freelist_blocks
from user_tables;
Note: Changes made to the above after reading this AskTom thread
If you don't want to import csv
module for that, you can write a list of lists to a csv file using only Python built-ins
with open("output.csv", "w") as f:
for row in a:
f.write("%s\n" % ','.join(str(col) for col in row))
Oh, dear. A few little problems...
As pointed out by others, you need to quote to protect against empty/space-containing entries, and use the !delayed_expansion! facility.
Two other matters of which you should be aware:
First, set/p
will assign a user-input value to a variable. That's not news - but the gotcha is that pressing enter
in response will leave the variable UNCHANGED - it will not ASSIGN a zero-length string to the variable (hence deleting the variable from the environment.) The safe method is:
set "var="
set /p var=
That is, of course, if you don't WANT enter
to repeat the existing value.
Another useful form is
set "var=default"
set /p var=
or
set "var=default"
set /p "var=[%var%]"
(which prompts with the default value; !var!
if in a block statement with delayedexpansion)
Second issue is that on some Windows versions (although W7 appears to "fix" this issue) ANY label - including a :: comment
(which is a broken-label) will terminate any 'block' - that is, parenthesised compound statement)
I just did it the old way i know that its not right but its a quick fix.

To load your data in WebView. Call loadData() method of WebView
wv.loadData(yourData, "text/html", "UTF-8");

To get a JSONObject or JSONArray from a String I've created this class:
public static class JSON {
public Object obj = null;
public boolean isJsonArray = false;
JSON(Object obj, boolean isJsonArray){
this.obj = obj;
this.isJsonArray = isJsonArray;
}
}
Here to get the JSON:
public static JSON fromStringToJSON(String jsonString){
boolean isJsonArray = false;
Object obj = null;
try {
JSONArray jsonArray = new JSONArray(jsonString);
Log.d("JSON", jsonArray.toString());
obj = jsonArray;
isJsonArray = true;
}
catch (Throwable t) {
Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
}
if (object == null) {
try {
JSONObject jsonObject = new JSONObject(jsonString);
Log.d("JSON", jsonObject.toString());
obj = jsonObject;
isJsonArray = false;
} catch (Throwable t) {
Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
}
}
return new JSON(obj, isJsonArray);
}
Example:
JSON json = fromStringToJSON("{\"message\":\"ciao\"}");
if (json.obj != null) {
// If the String is a JSON array
if (json.isJsonArray) {
JSONArray jsonArray = (JSONArray) json.obj;
}
// If it's a JSON object
else {
JSONObject jsonObject = (JSONObject) json.obj;
}
}
If you don't prefix with
?android:
your app will crash.
You should use "?android:attr/selectableItemBackground"
or "?android:attr/selectableItemBackgroundBorderless"
, based on your preference. I prefer Borderless
.
You can put it either in android:background
or android:foreground
to keep existing properties.
The element must have android:clickable="true"
and android:focusable="true"
in order for this to work, but many elements, such as buttons, have them true
by default.
<Button
...
android:background="@color/white"
android:foreground="?android:attr/selectableItemBackgroundBorderless"
/>
<TextView
...
android:background="?android:attr/selectableItemBackgroundBorderless"
android:clickable="true"
android:focusable="true"
/>
TypedValue value = new TypedValue();
context.getTheme().resolveAttribute(android.R.attr.selectableItemBackground, value, true);
myView.setBackgroundResource(value.resourceId);
myView.setFocusable(true); // If needed for view type
val value = TypedValue()
context.theme.resolveAttribute(android.R.attr.selectableItemBackground, value, true)
myView.setBackgroundResource(value.resourceId)
myView.setFocusable(true) // If needed for view type
myView.ripple()
fun View.ripple(): View {
val value = TypedValue()
context.theme.resolveAttribute(android.R.attr.selectableItemBackground, value, true)
setBackgroundResource(value.resourceId)
isFocusable = true // Required for some view types
return this
}
In postman, set method type to POST.
Then select Body -> form-data -> Enter your parameter name (file according to your code)
and on right side next to value column, there will be dropdown "text, file", select File. choose your image file and post it.
For rest of "text" based parameters, you can post it like normally you do with postman. Just enter parameter name and select "text" from that right side dropdown menu and enter any value for it, hit send button. Your controller method should get called.
Although TripleDESCryptoServiceProvider is a safe and good method but it's too slow. If you want to refer to MSDN you will get that advise you to use AES rather TripleDES. Please check below link: http://msdn.microsoft.com/en-us/library/system.security.cryptography.tripledescryptoserviceprovider.aspx you will see this attention in the remark section:
Note A newer symmetric encryption algorithm, Advanced Encryption Standard (AES), is available. Consider using the AesCryptoServiceProvider class instead of the TripleDESCryptoServiceProvider class. Use TripleDESCryptoServiceProvider only for compatibility with legacy applications and data.
Good luck
Extracting data from PDF is bound to be fraught with problems. Are the documents created through some kind of automatic process? If so, you might consider converting the PDFs to uncompressed PostScript (try pdf2ps) and seeing if the PostScript contains some sort of regular pattern which you can exploit.
another thing you could try is to rename your old jdk folder, lets say its:
C:\Program Files\Java\jdk1.7.0_04
change it to saomething like:
C:\Program Files\Java\xxxjdk1.7.0_04
Now, you should once again asked to set your jdk folder location on Oracle SqlDeveloper launch, and you can chose the right path.
Not the most elegant solution, but it worked for me.

I implemented this in the following way after receiving a NullPointerException
from the accepted answer.
In my FXML:
<Button onMouseClicked="#onMouseClickedCancelBtn" text="Cancel">

@FXML public void onMouseClickedCancelBtn(InputEvent e) {
final Node source = (Node) e.getSource();
final Stage stage = (Stage) source.getScene().getWindow();
stage.close();

If it's specifically zero length integers, then you want something like
is.integer0 <- function(x)
{
is.integer(x) && length(x) == 0L
}
Check it with:
is.integer0(integer(0)) #TRUE
is.integer0(0L) #FALSE
is.integer0(numeric(0)) #FALSE
You can also use assertive
for this.
library(assertive)
x <- integer(0)
assert_is_integer(x)
assert_is_empty(x)
x <- 0L
assert_is_integer(x)
assert_is_empty(x)
## Error: is_empty : x has length 1, not 0.
x <- numeric(0)
assert_is_integer(x)
assert_is_empty(x)
## Error: is_integer : x is not of class 'integer'; it has class 'numeric'.
Assuming that your original dataset is similar to the one you created (i.e. with NA
as character
. You could specify na.strings
while reading the data using read.table
. But, I guess NAs would be detected automatically.
The price
column is factor
which needs to be converted to numeric
class. When you use as.numeric
, all the non-numeric elements (i.e. "NA"
, FALSE) gets coerced to NA
) with a warning.
library(dplyr)
df %>%
mutate(price=as.numeric(as.character(price))) %>%
group_by(company, year, product) %>%
summarise(total.count=n(),
count=sum(is.na(price)),
avg.price=mean(price,na.rm=TRUE),
max.price=max(price, na.rm=TRUE))
I am using the same dataset
(except the ...
row) that was showed.
df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
"Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
"7.12", "12.99", "10.99", "NA",FALSE)))
"I am actually going to change the colors of these images based on what color scheme the user has chosen for my site." - Jordan 10 hours ago
I suggest you to use PHP for this. There's really no better way to do this without icon fonts, and if you resist using them, you could try this:
<?php
header('Content-Type: image/svg+xml');
echo '<?xml version="1.0" encoding="utf-8"?>';
$color = $_GET['color'];
?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 56.69 56.69">
<g>
<path fill="<?php echo $color; ?>" d="M28.44..."/>
</g>
</svg>
And later you could use this file as filename.php?color=#ffffff
to get the svg file in the desired color.

You're looking for the onclose event.

note that not all browsers support this (for example firefox 2)
The c++ inline
keyword is misleading, it doesn't mean "inline this function". If a function is defined as inline, it simply means that it can be defined multiple times as long as all definitions are equal. It's perfectly legal for a function marked inline
to be a real function that is called instead of getting code inlined at the point where it's called.
Defining a function in a header file is needed for templates, since e.g. a templated class isn't really a class, it's a template for a class which you can make multiple variations of. In order for the compiler to be able to e.g. make a Foo<int>::bar()
function when you use the Foo template to create a Foo class, the actual definition of Foo<T>::bar()
must be visible.
TLDR; technically space sorts before exclamation mar, and can be used by preceding it with ' or - (which will be ignored in sorting), but exclamation mark follows right after space, and is easier to use.
On windows 7 at least, a minus sign (-) and (') seem to be ignored in a name except for one quirk: in a name that is otherwise identical, the ' will be sorted before -, for example: (a'a) will sort above (a-a)
Empty string will sort above everything else, which means for example aa will sort above aaa because the 'empty string' after two a letters will sort before the third 'a'.
This also means that aa will be sorted above a'a because the 'empty string' between two a letters will sort above the ' mark.
What follows then is, ' alone will sort first, because technically it's an empty string. However adding for example letters behind it will sort the name as if the ' didn't exist.
Since the first 'unignored' character (as far as I know) is space, in case you want to sort 'real names' above others, the best way to go would be ' followed by space, and then the name you want to actually use. For example: (' first)
You can of course top that by using more than one space in the strong, such as (' firster) and (' firstest) with two and three blanks before the f.
While minus sign sorts below ' in otherwise similar name, there's no other difference in sorting (that I know of), and I find minus sign visually clearer, so if I want to put something on top of list, I'd use minus followed by space, then the 'actual name', for example: (- first file -)
If you are worried about using space on the filename, then exclamation mark (!) is the next best thing - and since it can appear as first character on a string, it's easier to use.
Change:
RANK() OVER (PARTITION BY ContenderNum ORDER BY totals ASC) AS xRank
to:
RANK() OVER (ORDER BY totals DESC) AS xRank
Have a look at this example:
You might also want to have a look at the difference between RANK (Transact-SQL) and DENSE_RANK (Transact-SQL):
RANK (Transact-SQL)
If two or more rows tie for a rank, each tied rows receives the same rank. For example, if the two top salespeople have the same SalesYTD value, they are both ranked one. The salesperson with the next highest SalesYTD is ranked number three, because there are two rows that are ranked higher. Therefore, the RANK function does not always return consecutive integers.
DENSE_RANK (Transact-SQL)
Returns the rank of rows within the partition of a result set, without any gaps in the ranking. The rank of a row is one plus the number of distinct ranks that come before the row in question.
It's not possible to use an array like that in PDO.
You need to build a string with a parameter (or use ?) for each value, for instance:
:an_array_0, :an_array_1, :an_array_2, :an_array_3, :an_array_4, :an_array_5
Here's an example:
<?php
$ids = array(1,2,3,7,8,9);
$sqlAnArray = join(
', ',
array_map(
function($index) {
return ":an_array_$index";
},
array_keys($ids)
)
);
$db = new PDO(
'mysql:dbname=mydb;host=localhost',
'user',
'passwd'
);
$stmt = $db->prepare(
'SELECT *
FROM table
WHERE id IN('.$sqlAnArray.')'
);
foreach ($ids as $index => $id) {
$stmt->bindValue("an_array_$index", $id);
}
If you want to keep using bindParam
, you may do this instead:
foreach ($ids as $index => $id) {
$stmt->bindParam("an_array_$index", $ids[$id]);
}
If you want to use ?
placeholders, you may do it like this:
<?php
$ids = array(1,2,3,7,8,9);
$sqlAnArray = '?' . str_repeat(', ?', count($ids)-1);
$db = new PDO(
'mysql:dbname=dbname;host=localhost',
'user',
'passwd'
);
$stmt = $db->prepare(
'SELECT *
FROM phone_number_lookup
WHERE country_code IN('.$sqlAnArray.')'
);
$stmt->execute($ids);
If you don't know if $ids
is empty, you should test it and handle that case accordingly (return an empty array, or return a Null Object, or throw an exception, ...).
It is hard to get pip working on El Capitan for several reasons:
/System/Library/
. El Capitan blocks this, which is the error you are running into. /System/Library/
. pip often wants to upgrade these but cannot on El Capitan. /System/Library/
higher in the python search order than /Library/Python/2.7/site-packages
(the system-wide python package location), so even if you manage to install newer versions of some packages, the old ones still get loaded, breaking some dependencies.There are workarounds for all of these at https://apple.stackexchange.com/a/223163/143849 . But you may be best off installing your own version of Python via the standard Python installer, Homebrew or Anaconda.
Using the so called f strings:
answer = True
myvar = f"the answer is {answer}"
Then if I do
print(myvar)
I will get:
the answer is True
I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.
The compiler replaces null comparisons with a call to HasValue
, so there is no real difference. Just do whichever is more readable/makes more sense to you and your colleagues.
You are making it complicated. string
is already nullable. You don't need to make it more nullable. Take out the ?
on the property type.
Spinlock and Mutex synchronization mechanisms are very common today to be seen.
Let's think about Spinlock first.
Basically it is a busy waiting action, which means that we have to wait for a specified lock is released before we can proceed with the next action. Conceptually very simple, while implementing it is not on the case. For example: If the lock has not been released then the thread was swap-out and get into the sleep state, should do we deal with it? How to deal with synchronization locks when two threads simultaneously request access ?
Generally, the most intuitive idea is dealing with synchronization via a variable to protect the critical section. The concept of Mutex is similar, but they are still different. Focus on: CPU utilization. Spinlock consumes CPU time to wait for do the action, and therefore, we can sum up the difference between the two:
In homogeneous multi-core environments, if the time spend on critical section is small than use Spinlock, because we can reduce the context switch time. (Single-core comparison is not important, because some systems implementation Spinlock in the middle of the switch)
In Windows, using Spinlock will upgrade the thread to DISPATCH_LEVEL, which in some cases may be not allowed, so this time we had to use a Mutex (APC_LEVEL).
If you take a look at:
you will notice that there are two variables used in the docker-entrypoint.sh
:
You can use them to setup root user. For example you can use following docker-compose.yml
file:
mongo-container:
image: mongo:3.4.2
environment:
# provide your credentials here
- MONGO_INITDB_ROOT_USERNAME=root
- MONGO_INITDB_ROOT_PASSWORD=rootPassXXX
ports:
- "27017:27017"
volumes:
# if you wish to setup additional user accounts specific per DB or with different roles you can use following entry point
- "$PWD/mongo-entrypoint/:/docker-entrypoint-initdb.d/"
# no --auth is needed here as presence of username and password add this option automatically
command: mongod
Now when starting the container by docker-compose up
you should notice following entries:
...
I CONTROL [initandlisten] options: { net: { bindIp: "127.0.0.1" }, processManagement: { fork: true }, security: { authorization: "enabled" }, systemLog: { destination: "file", path: "/proc/1/fd/1" } }
...
I ACCESS [conn1] note: no users configured in admin.system.users, allowing localhost access
...
Successfully added user: {
"user" : "root",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}
To add custom users apart of root use the entrypoint exectuable script (placed under $PWD/mongo-entrypoint dir as it is mounted in docker-compose
to entrypoint):
#!/usr/bin/env bash
echo "Creating mongo users..."
mongo admin --host localhost -u USER_PREVIOUSLY_DEFINED -p PASS_YOU_PREVIOUSLY_DEFINED --eval "db.createUser({user: 'ANOTHER_USER', pwd: 'PASS', roles: [{role: 'readWrite', db: 'xxx'}]}); db.createUser({user: 'admin', pwd: 'PASS', roles: [{role: 'userAdminAnyDatabase', db: 'admin'}]});"
echo "Mongo users created."
Entrypoint script will be executed and additional users will be created.
Could it be as simple as enclosing your asset in " " and whatever needs quotes on the inside with ' '?
<link rel="stylesheet" media="screen" href="@routes.Assets.at("stylesheets/main.css")">

That could be causing some problems with parsing
Take a look at the JavaDoc for RestTemplate.
There is the corresponding getForObject
methods that are the HTTP GET equivalents of postForObject
, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.
Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange
methods allow you to provide an HttpEntity
object representing the details of the request (including headers). The execute
methods allow you to specify a RequestCallback
from which you can add the headers upon its invocation.
Here an alternative using SUBSTRING
SELECT
SUBSTRING([Field], LEN([Field]) - 2, 3) [Right3],
SUBSTRING([Field], 0, LEN([Field]) - 2) [TheRest]
FROM
[Fields]
If you're talking about PL/SQL, you should put it in an anonymous block.
DECLARE
v_text VARCHAR2(10); -- declare
BEGIN
v_text := 'Hello'; --assign
dbms_output.Put_line(v_text); --display
END;
First, you should note that mixins only exist in multiple-inheritance languages. You can't do a mixin in Java or C#.
Basically, a mixin is a stand-alone base type that provides limited functionality and polymorphic resonance for a child class. If you're thinking in C#, think of an interface that you don't have to actually implement because it's already implemented; you just inherit from it and benefit from its functionality.
Mixins are typically narrow in scope and not meant to be extended.
[edit -- as to why:]
I suppose I should address why, since you asked. The big benefit is that you don't have to do it yourself over and over again. In C#, the biggest place where a mixin could benefit might be from the Disposal pattern. Whenever you implement IDisposable, you almost always want to follow the same pattern, but you end up writing and re-writing the same basic code with minor variations. If there were an extendable Disposal mixin, you could save yourself a lot of extra typing.
[edit 2 -- to answer your other questions]
What separates a mixin from multiple inheritance? Is it just a matter of semantics?
Yes. The difference between a mixin and standard multiple inheritance is just a matter of semantics; a class that has multiple inheritance might utilize a mixin as part of that multiple inheritance.
The point of a mixin is to create a type that can be "mixed in" to any other type via inheritance without affecting the inheriting type while still offering some beneficial functionality for that type.
Again, think of an interface that is already implemented.
I personally don't use mixins since I develop primarily in a language that doesn't support them, so I'm having a really difficult time coming up with a decent example that will just supply that "ahah!" moment for you. But I'll try again. I'm going to use an example that's contrived -- most languages already provide the feature in some way or another -- but that will, hopefully, explain how mixins are supposed to be created and used. Here goes:
Suppose you have a type that you want to be able to serialize to and from XML. You want the type to provide a "ToXML" method that returns a string containing an XML fragment with the data values of the type, and a "FromXML" that allows the type to reconstruct its data values from an XML fragment in a string. Again, this is a contrived example, so perhaps you use a file stream, or an XML Writer class from your language's runtime library... whatever. The point is that you want to serialize your object to XML and get a new object back from XML.
The other important point in this example is that you want to do this in a generic way. You don't want to have to implement a "ToXML" and "FromXML" method for every type that you want to serialize, you want some generic means of ensuring that your type will do this and it just works. You want code reuse.
If your language supported it, you could create the XmlSerializable mixin to do your work for you. This type would implement the ToXML and the FromXML methods. It would, using some mechanism that's not important to the example, be capable of gathering all the necessary data from any type that it's mixed in with to build the XML fragment returned by ToXML and it would be equally capable of restoring that data when FromXML is called.
And.. that's it. To use it, you would have any type that needs to be serialized to XML inherit from XmlSerializable. Whenever you needed to serialize or deserialize that type, you would simply call ToXML or FromXML. In fact, since XmlSerializable is a fully-fledged type and polymorphic, you could conceivably build a document serializer that doesn't know anything about your original type, accepting only, say, an array of XmlSerializable types.
Now imagine using this scenario for other things, like creating a mixin that ensures that every class that mixes it in logs every method call, or a mixin that provides transactionality to the type that mixes it in. The list can go on and on.
If you just think of a mixin as a small base type designed to add a small amount of functionality to a type without otherwise affecting that type, then you're golden.
Hopefully. :)
If you are using Windows, follow this:
The desired result can be obtained using IGrouping, which represents a collection of objects that have a common key in this case a GroupID
var newCustomerList = CustomerList.GroupBy(u => u.GroupID)
.Select(group => new { GroupID = group.Key, Customers = group.ToList() })
.ToList();
Here is all the information you need in order to format clickable hyperlinks in LaTeX:
http://en.wikibooks.org/wiki/LaTeX/Hyperlinks
Essentially, you use the hyperref
package and use the \url
or \href
tag depending on what you're trying to achieve.
What others have posted about running the function repeatedly in a loop is correct.
For Linux (and BSD) you want to use clock_gettime().
#include <sys/time.h>
int main()
{
timespec ts;
// clock_gettime(CLOCK_MONOTONIC, &ts); // Works on FreeBSD
clock_gettime(CLOCK_REALTIME, &ts); // Works on Linux
}
For windows you want to use the QueryPerformanceCounter. And here is more on QPC
Apparently there is a known issue with QPC on some chipsets, so you may want to make sure you do not have those chipset. Additionally some dual core AMDs may also cause a problem. See the second post by sebbbi, where he states:
QueryPerformanceCounter() and QueryPerformanceFrequency() offer a bit better resolution, but have different issues. For example in Windows XP, all AMD Athlon X2 dual core CPUs return the PC of either of the cores "randomly" (the PC sometimes jumps a bit backwards), unless you specially install AMD dual core driver package to fix the issue. We haven't noticed any other dual+ core CPUs having similar issues (p4 dual, p4 ht, core2 dual, core2 quad, phenom quad).
EDIT 2013/07/16:
It looks like there is some controversy on the efficacy of QPC under certain circumstances as stated in http://msdn.microsoft.com/en-us/library/windows/desktop/ee417693(v=vs.85).aspx
...While QueryPerformanceCounter and QueryPerformanceFrequency typically adjust for multiple processors, bugs in the BIOS or drivers may result in these routines returning different values as the thread moves from one processor to another...
However this StackOverflow answer https://stackoverflow.com/a/4588605/34329 states that QPC should work fine on any MS OS after Win XP service pack 2.
This article shows that Windows 7 can determine if the processor(s) have an invariant TSC and falls back to an external timer if they don't. http://performancebydesign.blogspot.com/2012/03/high-resolution-clocks-and-timers-for.html Synchronizing across processors is still an issue.
Other fine reading related to timers:
See the comments for more details.
You could store that const value in the enum like so. But why even use the const? Are you persisting the enum's?
public class SO3990319 {
public static enum PAGE {
SIGN_CREATE(1);
private final int constValue;
private PAGE(int constValue) {
this.constValue = constValue;
}
public int constValue() {
return constValue;
}
}
public static void main(String[] args) {
System.out.println("Name: " + PAGE.SIGN_CREATE.name());
System.out.println("Ordinal: " + PAGE.SIGN_CREATE.ordinal());
System.out.println("Const: " + PAGE.SIGN_CREATE.constValue());
System.out.println("Enum: " + PAGE.valueOf("SIGN_CREATE"));
}
}
Edit:
It depends on what you're using the int's for whether to use EnumMap or instance field.

My guess is that your video is incompatible with Android. Try it with a different video. This one definitely works used to work with Android (but does not on newer devices, for some reason). If that video works, and yours does not, then your video is not compatible with Android.
As others have indicated, please test this on a device. Video playback on the emulator requires too much power.

Without FileReader
, we can use URL.createObjectURL
method to get the DOMString that represents the object ( our image file ).
Don't forget to validate image extension.
<input type="file" id="files" multiple />
<div class="image-preview"></div>
let file_input = document.querySelector('#files');
let image_preview = document.querySelector('.image-preview');
const handle_file_preview = (e) => {
let files = e.target.files;
let length = files.length;
for(let i = 0; i < length; i++) {
let image = document.createElement('img');
// use the DOMstring for source
image.src = window.URL.createObjectURL(files[i]);
image_preview.appendChild(image);
}
}

CSV is a standard format, outlined in RFC 4180 (in 2005), so there IS no lack of a standard. https://www.ietf.org/rfc/rfc4180.txt
And even before that, the C in CSV has always stood for Comma, not for semiColon :(
It's a pity Microsoft keeps ignoring that and is still sticking to the monstrosity they turned it into decades ago (yes, I admit, that was before the RFC was created).
Only if text is enclosed in double quotation marks, such quotations marks in the text escaped by doubling. These examples represent the same three fields:
1,"this text contains ""quotation marks""",3
1,this text contains "quotation marks",3
The standard does not cover date and time values, personally I try to stick to ISO 8601 format to avoid day/month/year -- month/day/year confusion.
Quick fix that works for me. Navigate to the root directory of your folder from command line (cmd). then once you are on your root directory, type:
code .
Then, press enter. Note the ".", don't forget it. Now try to debug and see if you get the same error.
The syntax has changed in that print
is now a function. This means that the %
formatting needs to be done inside the parenthesis:1
print("%d. %s appears %d times." % (i, key, wordBank[key]))
However, since you are using Python 3.x., you should actually be using the newer str.format
method:
print("{}. {} appears {} times.".format(i, key, wordBank[key]))
Though %
formatting is not officially deprecated (yet), it is discouraged in favor of str.format
and will most likely be removed from the language in a coming version (Python 4 maybe?).
1Just a minor note: %d
is the format specifier for integers, not %s
.
You can also enable multiple GPU cores, like so:

for more advanced python editing consider installing the simplefold vim plugin. it allows you do advanced code folding using regular expressions. i use it to fold my class and method definitions for faster editing.
The Easiest way to do it is to have good site structure and write it as a constant.
DEFINE("BACK_ROOT","/var/www/");
The number of results can (theoretically) be greater than the range of an integer. I would refactor the code and work with the returned long value instead.
On a related note, if you only have the filename or relative path, dirname
on its own won't help. For me, the answer ended up being readlink
.
fname='txtfile'
echo $(dirname "$fname") # output: .
echo $(readlink -f "$fname") # output: /home/me/work/txtfile
You can then combine the two to get just the directory.
echo $(dirname $(readlink -f "$fname")) # output: /home/me/work

I submit that it is better to leave your data stacked as it is:
df = pandas.DataFrame(data, columns=['R_Number', 'C_Number', 'Avg', 'Std'])
# Possibly also this if these can always be the indexes:
# df = df.set_index(['R_Number', 'C_Number'])
Then it's a bit more intuitive to say
df.set_index(['R_Number', 'C_Number']).Avg.unstack(level=1)
This way it is implicit that you're seeking to reshape the averages, or the standard deviations. Whereas, just using pivot
, it's purely based on column convention as to what semantic entity it is that you are reshaping.

With C++17, you can use std::from_chars
, which is a lighter weight faster alternative to std::stof
and std::stod
. It doesn't involve any memory allocation or look at the locale, and it is non-throwing.
The std::from_chars
function returns a value of type from_chars_result
, which is basically a struct with two fields:
struct from_chars_result {
const char* ptr;
std::errc ec;
};
By inspecting ec
we can tell if the conversion was successful:
#include <iostream>
#include <charconv>
int main()
{
const std::string str { "12345678901234.123456" };
double value = 0.0;
auto [p, ec] = std::from_chars(str.data(), str.data() + str.size(), value);
if (ec != std::errc()) {
std::cout << "Couldn't convert value";
}
return 0;
}

In Windows 7, right-click on Computer -> Properties -> Advanced system settings; then in the Advanced tab, click Environment Variables... -> System variables -> New....
Give the new system variable the name JAVA_HOME
and the value C:\Program Files\Java\jdk1.7.0_79
(depending on your JDK installation path it varies).
Then select the Path
system variable and click Edit.... Keep the variable name as Path
, and append C:\Program Files\Java\jdk1.7.0_79\bin;
or %JAVA_HOME%\bin;
(both mean the same) to the variable value.
Once you are done with above changes, try below steps. If you don't see similar results, restart the computer and try again. If it still doesn't work you may need to reinstall JDK.
Open a Windows command prompt (Windows key + R -> enter cmd
-> OK), and check the following:
java -version
You will see something like this:
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
Then check the following:

would work: i.e. return the count of complete months between two dates, ignoring any partial months. Because it's based on DateTime.AddMonths()
it respects different month lengths and returns what a human would understand as a period of months.
(Unfortunately you can't implement it as an extension method on TimeSpan because that doesn't retain knowledge of the actual dates used, and for months they're important.)
The code and tests are both available on GitHub. The code is very simple:
public static int GetTotalMonthsFrom(this DateTime dt1, DateTime dt2)
{
DateTime earlyDate = (dt1 > dt2) ? dt2.Date : dt1.Date;
DateTime lateDate = (dt1 > dt2) ? dt1.Date : dt2.Date;
// Start with 1 month's difference and keep incrementing
// until we overshoot the late date
int monthsDiff = 1;
while (earlyDate.AddMonths(monthsDiff) <= lateDate)
{
monthsDiff++;
}
return monthsDiff - 1;
}
And it passes all these unit test cases:
// Simple comparison
Assert.AreEqual(1, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 2, 1)));
// Just under 1 month's diff
Assert.AreEqual(0, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 1, 31)));
// Just over 1 month's diff
Assert.AreEqual(1, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 2, 2)));
// 31 Jan to 28 Feb
Assert.AreEqual(1, new DateTime(2014, 1, 31).GetTotalMonthsFrom(new DateTime(2014, 2, 28)));
// Leap year 29 Feb to 29 Mar
Assert.AreEqual(1, new DateTime(2012, 2, 29).GetTotalMonthsFrom(new DateTime(2012, 3, 29)));
// Whole year minus a day
Assert.AreEqual(11, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2012, 12, 31)));
// Whole year
Assert.AreEqual(12, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2013, 1, 1)));
// 29 Feb (leap) to 28 Feb (non-leap)
Assert.AreEqual(12, new DateTime(2012, 2, 29).GetTotalMonthsFrom(new DateTime(2013, 2, 28)));
// 100 years
Assert.AreEqual(1200, new DateTime(2000, 1, 1).GetTotalMonthsFrom(new DateTime(2100, 1, 1)));
// Same date
Assert.AreEqual(0, new DateTime(2014, 8, 5).GetTotalMonthsFrom(new DateTime(2014, 8, 5)));
// Past date
Assert.AreEqual(6, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2011, 6, 10)));
Where on earth did you find this syntax? Java Enums are very simple, you just specify the values.
public enum Gender {
MALE,
FEMALE
}
If you want them to be more complex, you can add values to them like this.
public enum Gender {
MALE("Male", 0),
FEMALE("Female", 1);
private String stringValue;
private int intValue;
private Gender(String toString, int value) {
stringValue = toString;
intValue = value;
}
@Override
public String toString() {
return stringValue;
}
}
Then to use the enum, you would do something like this:
Gender me = Gender.MALE
The "adjustment" in adjusted R-squared is related to the number of variables and the number of observations.
If you keep adding variables (predictors) to your model, R-squared will improve - that is, the predictors will appear to explain the variance - but some of that improvement may be due to chance alone. So adjusted R-squared tries to correct for this, by taking into account the ratio (N-1)/(N-k-1) where N = number of observations and k = number of variables (predictors).
It's probably not a concern in your case, since you have a single variate.
Some references:
You can also do this using DOM Level 2 CSS interfaces (MDN):
var sheet = window.document.styleSheets[0];
sheet.insertRule('strong { color: red; }', sheet.cssRules.length);
...on all but (naturally) IE8 and prior, which uses its own marginally-different wording:
sheet.addRule('strong', 'color: red;', -1);
There is a theoretical advantage in this compared to the createElement-set-innerHTML method, in that you don't have to worry about putting special HTML characters in the innerHTML, but in practice style elements are CDATA in legacy HTML, and ‘<’ and ‘&’ are rarely used in stylesheets anyway.
You do need a stylesheet in place before you can started appending to it like this. That can be any existing active stylesheet: external, embedded or empty, it doesn't matter. If there isn't one, the only standard way to create it at the moment is with createElement.
You can't increase the array's length if it is not declared in heap memory (see below code which first array input is asked by user and then it asks how much you want to increase array and also copy previous array elements):
#include<stdio.h>
#include<stdlib.h>
int * increasesize(int * p,int * q,int x)
{
int i;
for(i=0;i<x;i++)
{
q[i]=p[i];
}
free(p);
p=q;
return p;
}
void display(int * q,int x)
{
int i;
for(i=0;i<x;i++)
{
printf("%d \n",q[i]);
}
}
int main()
{
int x,i;
printf("enter no of element to create array");
scanf("%d",&x);
int * p=(int *)malloc(x*sizeof(int));
printf("\n enter number in the array\n");
for(i=0;i<x;i++)
{
scanf("%d",&p[i]);
}
int y;
printf("\nenter the new size to create new size of array");
scanf("%d",&y);
int * q=(int *)malloc(y*sizeof(int));
display(increasesize(p,q,x),y);
free(q);
}
The problem is that you can't use a list
as the key in a dict
, since dict
keys need to be immutable. Use a tuple instead.
This is a list:
[x, y]
This is a tuple:
(x, y)
Note that in most cases, the (
and )
are optional, since ,
is what actually defines a tuple (as long as it's not surrounded by []
or {}
, or used as a function argument).
You might find the section on tuples in the Python tutorial useful:
Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.
And in the section on dictionaries:
Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().
In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.
This error can happen if you are instantiating a fragment that somehow can't be instantiated:
Fragment myFragment = MyFragment.NewInstance();
public classs MyFragment extends Fragment {
public void onCreate() {
// Some error here, or anywhere inside the class is preventing it from being instantiated
}
}
In my case, i have met this when i tried to use:
private String loading = getString(R.string.loading);
If you need special memory alignment on the object controlled by shared_ptr, you cannot rely on make_shared, but I think it's the only one good reason about not using it.
Changing the NPM repo URL to HTTP works as a quick-fix, but I wanted to use HTTPS.
In my case, the proxy at my employer (ZScaler) was causing issues (as it acts as a MITM, causing certification verification issues)
I forgot I found a script that helps with this and Git (for cloning GitHub repos via HTTPS had the same issue) and forked it for my use
Basically, it does the following for git:
git config --global http.proxy http://gateway.zscaler.net:80/
git config --system http.proxy http://gateway.zscaler.net:80/
and for Node, it adds proxy=http://gateway.zscaler.net:80/
to the end of c:\Users\$USERNAME\npm\.npmrc
That solved the issue for me.
You could just set the width to auto. Then the width of the div will equal 0 if it has no content.
width:auto;
You can also hide spinner with following trick :
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
opacity:0;
pointer-events:none;
}
I do not know whether this is the general opinion, but I've always differentiated the two by what they are used for. An emulator is used if you actually want to use the emulated machine for its output. A simulator, on the other hand, is for when you want to study the simulated machine or test its behaviour.
For example, if you want to write some state machine logic in your application (which is running on a general purpose CPU), you write a small state machine emulator. If you want to study the efficiency or viability of a state machine for a particular problem, you write a simulator.
If you want to display an image file on the phone, you can do this:
private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);
mImageView.setImageBitmap(BitmapFactory.decodeFile("pathToImageFile"));
If you want to display an image from your drawable resources, do this:
private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);
mImageView.setImageResource(R.drawable.imageFileId);
You'll find the drawable
folder(s) in the project res
folder. You can put your image files there.
Say:
sed "s|\$ROOT|${HOME}|" abc.sh
Note:
/
since the replacement contains /
$
in the pattern since you don't want to expand it.EDIT: In order to replace all occurrences of $ROOT
, say
sed "s|\$ROOT|${HOME}|g" abc.sh
For custom color to TitleText
at NavigationBar
, here a simple and short code for Swift 3:
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white]
or
navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName :UIColor.white]
DESCRIBE DATABASE NAME; you need to specify the name of the database and the results will include the data type of each attribute.
For a colloquial name there is "splatting".
For arguments (list type) you use single *
and for keyword arguments (dictionary type) you use double **
.
Both *
and **
is sometimes referred to as "splatting".
See for reference of this name being used: https://stackoverflow.com/a/47875892/14305096
In iOS7, if your navigation controller is contained in tab bar, splitview or some other container, then for globally changing navigationbar appearance use following method ::
[[UINavigationBar appearanceWhenContainedIn:[UITabBarController class],nil] setBarTintColor:[UIColor blueColor]];
I had the same problem and only this solution worked for me (it runs a function after a complete DOM has been loaded). I use this for scroll to anchor after page has been loaded:
angular.element(window.document.body).ready(function () {
// Your function that runs after all DOM is loaded
});
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
[object blockToExecute:^{
// ... your code to execute
dispatch_semaphore_signal(sema);
}];
while (dispatch_semaphore_wait(semaphore, DISPATCH_TIME_NOW)) {
[[NSRunLoop currentRunLoop]
runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0]];
}
This did it for me.
Just be aware that on Unix/Linux your username/password can be seen by anyone that can run "ps -ef" command if you place it directly on the command line . Could be a big security issue (or turn into a big security issue).
I usually recommend creating a file or using here document so you can protect the username/password from being viewed with "ps -ef" command in Unix/Linux. If the username/password is contained in a script file or sql file you can protect using appropriate user/group read permissions. Then you can keep the user/pass inside the file like this in a shell script:
sqlplus -s /nolog <<EOF
connect user/pass
select blah;
quit
EOF
This sounds like an output formatting issue? If using SQL Plus, use the COLUMN command like this (assuming you want a maximum display width of 20 chars for each):
column a format a20
column b format a20
select a, b from mytable;
A couple of notes first: when you use Data/data1.txt
as an argument, should it really be /Data/data1.txt
(with a leading slash)? Also, should the outer loop scan only for .txt files, or all files in /Data? Here's an answer, assuming /Data/data1.txt
and .txt files only:
#!/bin/bash
for filename in /Data/*.txt; do
for ((i=0; i<=3; i++)); do
./MyProgram.exe "$filename" "Logs/$(basename "$filename" .txt)_Log$i.txt"
done
done
Notes:
/Data/*.txt
expands to the paths of the text files in /Data (including the /Data/ part)$( ... )
runs a shell command and inserts its output at that point in the command linebasename somepath .txt
outputs the base part of somepath, with .txt removed from the end (e.g. /Data/file.txt
-> file
)If you needed to run MyProgram with Data/file.txt
instead of /Data/file.txt
, use "${filename#/}"
to remove the leading slash. On the other hand, if it's really Data
not /Data
you want to scan, just use for filename in Data/*.txt
.
Solution is to wrap your padded div, with fixed width outer div
HTML
<div class="outer">
<div class="inner">
<!-- your content -->
</div><!-- end .inner -->
</div><!-- end .outer -->
CSS
.outer, .inner {
display: block;
}
.outer {
/* specify fixed width */
width: 300px;
padding: 0;
}
.inner {
/* specify padding, can be changed while remaining fixed width of .outer */
padding: 5px;
}
I followed below steps to install mcrypt for PHP7.2 using PECL.
apt-get install php-pecl
apt-get install libmcrypt-dev libreadline-dev
pecl install mcrypt-1.0.1
You should add "extension=mcrypt.so" to php.ini
Please comment below if you need any assistance. :-)
IMPORTANT !
According to php.net reference many (all) mcrypt functions have been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.
DataGridView.Refresh
and And DataGridView.Update
are methods that are inherited from Control. They have to do with redrawing the control which is why new rows don't appear.
My guess is the data retrieval is on the Form_Load. If you want your Button on Form B to retrieve the latest data from the database then that's what you have to do whatever Form_Load is doing.
A nice way to do that is to separate your data retrieval calls into a separate function and call it from both the From Load and Button Click events.
You can write a PL/SQL function to return that cursor (or you could put that function in a package if you have more code related to this):
CREATE OR REPLACE FUNCTION get_allitems
RETURN SYS_REFCURSOR
AS
my_cursor SYS_REFCURSOR;
BEGIN
OPEN my_cursor FOR SELECT * FROM allitems;
RETURN my_cursor;
END get_allitems;
This will return the cursor.
Make sure not to put your SELECT
-String into quotes in PL/SQL when possible. Putting it in strings means that it can not be checked at compile time, and that it has to be parsed whenever you use it.
If you really need to use dynamic SQL you can put your query in single quotes:
OPEN my_cursor FOR 'SELECT * FROM allitems';
This string has to be parsed whenever the function is called, which will usually be slower and hides errors in your query until runtime.
Make sure to use bind-variables where possible to avoid hard parses:
OPEN my_cursor FOR 'SELECT * FROM allitems WHERE id = :id' USING my_id;
You can find a solution on SuperUser :
Chrome cookies folder in Windows 7:-
C:\Users\your_username\AppData\Local\Google\Chrome\User Data\Default\
You'll need a program like SQLite Database Browser to read it.
For Mac OS X, the file is located at :-

Use setItem
and getItem
if you want to write simple strings to localStorage. Also you should be using text()
if it's the text you're after as you say, else you will get the full HTML as a string.
// get the text
var text = $('#test').text();
// set the item in localStorage
localStorage.setItem('test', text);
// alert the value to check if we got it
alert(localStorage.getItem('test'));
JSFiddle: https://jsfiddle.net/f3zLa3zc/
// get html
var html = $('#test')[0].outerHTML;
// set localstorage
localStorage.setItem('htmltest', html);
// test if it works
alert(localStorage.getItem('htmltest'));
JSFiddle:
https://jsfiddle.net/psfL82q3/1/
A user want to update the localStorage when the div's content changes. Since it's unclear how the div contents changes (ajax, other method?) contenteditable
and blur()
is used to change the contents of the div and overwrite the old localStorage
entry.
// get the text
var text = $('#test').text();
// set the item in localStorage
localStorage.setItem('test', text);
// bind text to 'blur' event for div
$('#test').on('blur', function() {
// check the new text
var newText = $(this).text();
// overwrite the old text
localStorage.setItem('test', newText);
// test if it works
alert(localStorage.getItem('test'));
});
If we were using ajax we would instead trigger the function it via the function responsible for updating the contents.

Firstly, add path of visual studio common tools (c:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools
) into the system path. To learn how to add a path into system path, please check this website:
http://www.computerhope.com/issues/ch000549.htm. You just need to this once.
After that, whenever you need, open a command line and execute vsvars32.bat
to add all required visual studio tools' paths into the system path.
Then, you can call nmake -f makefile.mak
PS: Path of visual studio common tools might be different in your system. Please change it accordingly.
The technically correct way to store IPv4 is binary(4), since that is what it actually is (no, not even an INT32/INT(4), the numeric textual form that we all know and love (255.255.255.255) being just the display conversion of its binary content).
If you do it this way, you will want functions to convert to and from the textual-display format:
Here's how to convert the textual display form to binary:
CREATE FUNCTION dbo.fnBinaryIPv4(@ip AS VARCHAR(15)) RETURNS BINARY(4)
AS
BEGIN
DECLARE @bin AS BINARY(4)
SELECT @bin = CAST( CAST( PARSENAME( @ip, 4 ) AS INTEGER) AS BINARY(1))
+ CAST( CAST( PARSENAME( @ip, 3 ) AS INTEGER) AS BINARY(1))
+ CAST( CAST( PARSENAME( @ip, 2 ) AS INTEGER) AS BINARY(1))
+ CAST( CAST( PARSENAME( @ip, 1 ) AS INTEGER) AS BINARY(1))
RETURN @bin
END
go
And here's how to convert the binary back to the textual display form:
CREATE FUNCTION dbo.fnDisplayIPv4(@ip AS BINARY(4)) RETURNS VARCHAR(15)
AS
BEGIN
DECLARE @str AS VARCHAR(15)
SELECT @str = CAST( CAST( SUBSTRING( @ip, 1, 1) AS INTEGER) AS VARCHAR(3) ) + '.'
+ CAST( CAST( SUBSTRING( @ip, 2, 1) AS INTEGER) AS VARCHAR(3) ) + '.'
+ CAST( CAST( SUBSTRING( @ip, 3, 1) AS INTEGER) AS VARCHAR(3) ) + '.'
+ CAST( CAST( SUBSTRING( @ip, 4, 1) AS INTEGER) AS VARCHAR(3) );
RETURN @str
END;
go
Here's a demo of how to use them:
SELECT dbo.fnBinaryIPv4('192.65.68.201')
--should return 0xC04144C9
go
SELECT dbo.fnDisplayIPv4( 0xC04144C9 )
-- should return '192.65.68.201'
go
Finally, when doing lookups and compares, always use the binary form if you want to be able to leverage your indexes.
UPDATE:
I wanted to add that one way to address the inherent performance problems of scalar UDFs in SQL Server, but still retain the code-reuse of a function is to use an iTVF (inline table-valued function) instead. Here's how the first function above (string to binary) can be re-written as an iTVF:
CREATE FUNCTION dbo.itvfBinaryIPv4(@ip AS VARCHAR(15)) RETURNS TABLE
AS RETURN (
SELECT CAST(
CAST( CAST( PARSENAME( @ip, 4 ) AS INTEGER) AS BINARY(1))
+ CAST( CAST( PARSENAME( @ip, 3 ) AS INTEGER) AS BINARY(1))
+ CAST( CAST( PARSENAME( @ip, 2 ) AS INTEGER) AS BINARY(1))
+ CAST( CAST( PARSENAME( @ip, 1 ) AS INTEGER) AS BINARY(1))
AS BINARY(4)) As bin
)
go
Here's it in the example:
SELECT bin FROM dbo.fnBinaryIPv4('192.65.68.201')
--should return 0xC04144C9
go
And here's how you would use it in an INSERT
INSERT INTo myIpTable
SELECT {other_column_values,...},
(SELECT bin FROM dbo.itvfBinaryIPv4('192.65.68.201'))
The top answer here was a work around from an Angular problem which no longer exists (at least in versions >1.2.16 and "probably earlier") as @zumalifeguard has mentioned. But I'm left reading all these answers without an actual solution.
It seems to me that the answer now should be
$broadcast
from the $rootScope
$on
from the local $scope
that needs to know about the eventSo to publish
// EXAMPLE PUBLISHER
angular.module('test').controller('CtrlPublish', ['$rootScope', '$scope',
function ($rootScope, $scope) {
$rootScope.$broadcast('topic', 'message');
}]);
And subscribe
// EXAMPLE SUBSCRIBER
angular.module('test').controller('ctrlSubscribe', ['$scope',
function ($scope) {
$scope.$on('topic', function (event, arg) {
$scope.receiver = 'got your ' + arg;
});
}]);
Plunkers
Controller As
syntaxIf you register the listener on the local $scope
, it will be destroyed automatically by $destroy
itself when the associated controller is removed.
If you are inserting using PHP, and you have followed the various ALTER database and ALTER table options above, make sure your php connection's charset is utf8mb4.
Example of connection string:
$this->pdo = new PDO("mysql:host=$ip;port=$port;dbname=$db;charset=utf8mb4", etc etc
Notice the "charset" is utf8mb4, not just utf8!
Consider using the bootstrap-modal plugin found here - https://github.com/jschr/bootstrap-modal
The plugin will center all of your modals
.outside {
width: 200px;
height: 200px;
background-color: #EEE; /*to make it visible*/
}
Needs to be
.outside {
position: relative;
width: 200px;
height: 200px;
background-color: #EEE; /*to make it visible*/
}
Absolute positioning looks for the nearest relatively positioned parent within the DOM, if one isn't defined it will use the body.
The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr)
instead of 1fr
as your track size.
Everything is dangerous if you don't know what you are doing
Even high-precision decimal types can't save the day:
declare @num1 numeric(38,22)
declare @num2 numeric(38,22)
set @num1 = .0000006
set @num2 = 1.0
select @num1 * @num2 * 1000000
1.000000 <- Should be 0.6000000
The money
types are integers
The text representations of smallmoney
and decimal(10,4)
may look alike, but that doesn't make them interchangeable. Do you cringe when you see dates stored as varchar(10)
? This is the same thing.
Behind the scenes, money
/smallmoney
are just a bigint
/int
The decimal point in the text representation of money
is visual fluff, just like the dashes in a yyyy-mm-dd date. SQL doesn't actually store those internally.
Regarding decimal
vs money
, pick whatever is appropriate for your needs. The money
types exist because storing accounting values as integer multiples of 1/10000th of unit is very common. Also, if you are dealing with actual money and calculations beyond simple addition and subtraction, you shouldn't be doing that at the database level! Do it at the application level with a library that supports Banker's Rounding (IEEE 754)
I had a similar situation with this issue. In this case it would have looked like this
Sub Test()
MsqBox ("Hello world")
End Sub
The problem was, that I had a lot more code there and couldn't recognize, that there was a misspelling in "MsqBox" (q instead of g) and therefore I had an error, it was really misleading, but since you can get on this error like that, maybe someone else will notice that it was cause by a misspelling like this...
A 'button' is just that, a button, to which you can add additional functionality using Javascript. A 'submit' input type has the default functionality of submitting the form it's placed in (though, of course, you can still add additional functionality using Javascript).
//set vars
$user = $_POST['user'];
$pass = md5($_POST['pass']);
if ($user&&$pass)
{
//connect to db
$connect = mysql_connect("$server","$username","$password") or die("not connecting");
mysql_select_db("users") or die("no db :'(");
$query = mysql_query("SELECT * FROM $tablename WHERE username='$user'");
$numrows = mysql_num_rows($query);
if ($numrows!=0)
{
//while loop
while ($row = mysql_fetch_assoc($query))
{
$dbusername = $row['username'];
$dbpassword = $row['password'];
}
else
die("incorrect username/password!");
}
else
echo "user does not exist!";
}
else
die("please enter a username and password!");
When you change your passwords in the security tab, there are two sections, one above and one below. I think the common mistake here is that others try to log-in with the account they have set "below" the one used for htaccess, whereas they should log in to the password they set on the above section. That's how I fixed mine.
If you want to model at diagram level and also have a clean metamodel the new Omondo build allows live synchronization between MOF and UML Diagrams. Just amazing to see my diagram and the xmi live synchronized each time I change something in my diagram and the model is changed. What is most incredible is that the model is also the metamodel and the MOF because everything is lived synchronized. Very powerful new concept for my point of view.
I also like Java code annotation and JPA support in the class diagram and in the model. I don't know any other tool having these 2 incredible features !!
file:///
is a URI (Uniform Resource Identifier) that simply distinguishes from the standard URI that we all know of too well - http://
.
It does imply an absolute path name pointing to the root directory in any environment, but in the context of Android, it's a convention to tell the Android run-time to say "Here, the directory www
has a file called index.html
located in the assets
folder in the root of the project".
That is how assets are loaded at runtime, for example, a WebView
widget would know exactly where to load the embedded resource file by specifying the file:///
URI.
Consider the code example:
WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/www/index.html");
A very easy mistake to make here is this, some would infer it to as file:///android_assets
, notice the plural of assets in the URI and wonder why the embedded resource is not working!
Trying to make this as short and simple as possible. Creates directory if it doesn't exist, and then returns the desired file:
/** Creates parent directories if necessary. Then returns file */
private static File fileWithDirectoryAssurance(String directory, String filename) {
File dir = new File(directory);
if (!dir.exists()) dir.mkdirs();
return new File(directory + "/" + filename);
}
This does not answer the question fully, but for anyone who is able to calculate the number of days by which they would like to offset an initial date then the following method will work:
myDate.setUTCDate(myDate.getUTCDate() + offsetDays);
offsetDays can be positive or negative and the result will be correct for any given initial date with any given offset.

Thanks Yannis, your solution worked for me and here I'm sharing same solution for multiple keywords with order and limit.
Check android studio event log as it could be low storage issue.
emulator: ERROR: Not enough disk space to run AVD 'Nexus_5_API_21'. Exiting...
When the user starts making changes to the form, a boolean flag will be set. If the user then tries to navigate away from the page, you check that flag in the window.onunload event. If the flag is set, you show the message by returning it as a string. Returning the message as a string will popup a confirmation dialog containing your message.
If you are using ajax to commit the changes, you can set the flag to false
after the changes have been committed (i.e. in the ajax success event).
Yes, use DialogFragment
and in onCreateDialog
you can simply use an AlertDialog builder anyway to create a simple AlertDialog
with Yes/No confirmation buttons. Not very much code at all.
With regards handling events in your fragment there would be various ways of doing it but I simply define a message Handler
in my Fragment
, pass it into the DialogFragment
via its constructor and then pass messages back to my fragment's handler as approprirate on the various click events. Again various ways of doing that but the following works for me.
In the dialog hold a message and instantiate it in the constructor:
private Message okMessage;
...
okMessage = handler.obtainMessage(MY_MSG_WHAT, MY_MSG_OK);
Implement the onClickListener
in your dialog and then call the handler as appropriate:
public void onClick(.....
if (which == DialogInterface.BUTTON_POSITIVE) {
final Message toSend = Message.obtain(okMessage);
toSend.sendToTarget();
}
}
Edit
And as Message
is parcelable you can save it out in onSaveInstanceState
and restore it
outState.putParcelable("okMessage", okMessage);
Then in onCreate
if (savedInstanceState != null) {
okMessage = savedInstanceState.getParcelable("okMessage");
}
Ultimately you want to review the datetime documentation and become familiar with the formatting variables, but here are some examples to get you started:
import datetime
print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Date now: %s' % datetime.datetime.now())
print('Date today: %s' % datetime.date.today())
today = datetime.date.today()
print("Today's date is {:%b, %d %Y}".format(today))
schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'
schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'
print('Maintenance: %s' % schedule)
print('Maintenance: %s' % schedule2)
The output:
Timestamp: 2014-10-18 21:31:12
Timestamp: 2014-Oct-18 21:31:12
Date now: 2014-10-18 21:31:12.318340
Date today: 2014-10-18
Today's date is Oct, 18 2014
Maintenance: Oct, 18 2014 - 6 PM to 10 PM Pacific
Maintenance: October, 18 2014 - 1 PM to 6 PM Central

At first you need to add semi colon (;) after quantity INT NOT NULL)
then remove ** from ,genre,quantity)**
.
to insert a value with numeric data type like int, decimal, float, etc you don't need to add single quote.
Stored procedures in SQL Server can accept input parameters and return multiple values of output parameters; in SQL Server, stored procedures program statements to perform operations in the database and return a status value to a calling procedure or batch.
The benefits of using stored procedures in SQL Server
They allow modular programming. They allow faster execution. They can reduce network traffic. They can be used as a security mechanism.
Here is an example of a stored procedure that takes a parameter, executes a query and return a result. Specifically, the stored procedure accepts the BusinessEntityID as a parameter and uses this to match the primary key of the HumanResources.Employee table to return the requested employee.
> create procedure HumanResources.uspFindEmployee `*<<<---Store procedure name`*
@businessEntityID `<<<----parameter`
as
begin
SET NOCOUNT ON;
Select businessEntityId, <<<----select statement to return one employee row
NationalIdNumber,
LoginID,
JobTitle,
HireData,
From HumanResources.Employee
where businessEntityId =@businessEntityId <<<---parameter used as criteria
end
I learned this from essential.com...it is very useful.
Yes. But you can't redefine built-in types. You have to subclass them:
class MyTuple(tuple): def __add__(self, other): if len(self) != len(other): raise ValueError("tuple lengths don't match") return MyTuple(x + y for (x, y) in zip(self, other))
$('#btn1, #btn2').click(function() {
let clickedButton = $(this).attr('id');
console.log(clickedButton);
});
Use the display property
a{
display: block;
}
This will make the link to display in new line
If you want to remove list styling, use
li{
list-style: none;
}
This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):
SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC
This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.
Simply go to your root folder and run this command:
chmod a+rw .git/FETCH_HEAD
A version of Otto Nascarella's solution that works in strict mode is:
button.addEventListener('click', function handler() {
///this will execute only once
alert('only once!');
this.removeEventListener('click', handler);
});
Place your third party libraries in a separate repository and use submodules to associate them with the main project. Here is a walk-through:
http://git-scm.com/book/en/Git-Tools-Submodules
In deciding how to segment a repo I would usually decide based on how often I would modify them. If it is a third-party library and only changes you are making to it is upgrading to a newer version then you should definitely separate it from the main project.
In App.js
add the below code and try
window.location.pathname
that's just a shorthand notation in most languages.which means that
x=x+1;
we can do the same operation for x-=1,x*=1,x/=1; which means
Here's something based on Jerub's "naive approach" (naive being his words, not mine!):
import string
ALLOWED = frozenset(string.ascii_letters + string.digits + '_' + '-')
def check(mystring):
return all(c in ALLOWED for c in mystring)
If ALLOWED
was a string then I think c in ALLOWED
would involve iterating over each character in the string until it found a match or reached the end. Which, to quote Joel Spolsky, is something of a Shlemiel the Painter algorithm.
But testing for existence in a set should be more efficient, or at least less dependent on the number of allowed characters. Certainly this approach is a little bit faster on my machine. It's clear and I think it performs plenty well enough for most cases (on my slow machine I can validate tens of thousands of short-ish strings in a fraction of a second). I like it.
ACTUALLY on my machine a regexp works out several times faster, and is just as simple as this (arguably simpler). So that probably is the best way forward.

Using the BCNF definition
If and only if for every one of its dependencies X ? Y, at least one of the following conditions hold:
and the 3NF definition
If and only if, for each of its functional dependencies X ? A, at least one of the following conditions holds:
whereas
Where
That is, no partial subset (any non trivial subset except the full set) of a candidate key can be functionally dependent on anything other than a superkey.
A table/relation not in BCNF is subject to anomalies such as the update anomalies mentioned in the pizza example by another user. Unfortunately,
An example of the difference can currently be found at "3NF table not meeting BCNF (Boyce–Codd normal form)" on Wikipedia, where the following table meets 3NF but not BCNF because "Tennis Court" (a partial key/prime attribute) depends on "Rate Type" (a partial key/prime attribute that is not a superkey), which is a dependency we could determine by asking the clients of the database, the tennis club:
Today's Tennis Court Bookings (3NF, not BCNF)
Court Start Time End Time Rate Type
------- ---------- -------- ---------
1 09:30 10:30 SAVER
1 11:00 12:00 SAVER
1 14:00 15:30 STANDARD
2 10:00 11:30 PREMIUM-B
2 11:30 13:30 PREMIUM-B
2 15:00 16:30 PREMIUM-A
The table's superkeys are:
S1 = {Court, Start Time}
S2 = {Court, End Time}
S3 = {Rate Type, Start Time}
S4 = {Rate Type, End Time}
S5 = {Court, Start Time, End Time}
S6 = {Rate Type, Start Time, End Time}
S7 = {Court, Rate Type, Start Time}
S8 = {Court, Rate Type, End Time}
ST = {Court, Rate Type, Start Time, End Time}, the trivial superkey
The 3NF problem: The partial key/prime attribute "Court" is dependent on something other than a superkey. Instead, it is dependent on the partial key/prime attribute "Rate Type". This means that the user must manually change the rate type if we upgrade a court, or manually change the court if wanting to apply a rate change.
(In technical terms, we cannot guarantee that the "Rate Type" -> "Court" functional dependency will not be violated.)
The BCNF solution: If we want to place the above table in BCNF we can decompose the given relation/table into the following two relations/tables (assuming we know that the rate type is dependent on only the court and membership status, which we could discover by asking the clients of our database, the owners of the tennis club):
Rate Types (BCNF and the weaker 3NF, which is implied by BCNF)
Rate Type Court Member Flag
--------- ----- -----------
SAVER 1 Yes
STANDARD 1 No
PREMIUM-A 2 Yes
PREMIUM-B 2 No
Today's Tennis Court Bookings (BCNF and the weaker 3NF, which is implied by BCNF)
Member Flag Court Start Time End Time
----------- ----- ---------- --------
Yes 1 09:30 10:30
Yes 1 11:00 12:00
No 1 14:00 15:30
No 2 10:00 11:30
No 2 11:30 13:30
Yes 2 15:00 16:30
Problem Solved: Now if we upgrade the court we can guarantee the rate type will reflect this change, and we cannot charge the wrong price for a court.
(In technical terms, we can guarantee that the functional dependency "Rate Type" -> "Court" will not be violated.)
DiffUtil can the best choice for updating the data in the RecyclerView Adapter which you can find in the android framework. DiffUtil is a utility class that can calculate the difference between two lists and output a list of update operations that converts the first list into the second one.
Most of the time our list changes completely and we set new list to RecyclerView Adapter. And we call notifyDataSetChanged to update adapter. NotifyDataSetChanged is costly. DiffUtil class solves that problem now. It does its job perfectly!
Yes, gcc can also compile assembly source code. Alternatively, you can invoke as
, which is the assembler. (gcc is just a "driver" program that uses heuristics to call C compiler, C++ compiler, assembler, linker, etc..)
In my case was Promise with no reject neither resolve, because my Promise function threw an exception. This mistake cause UnhandledPromiseRejectionWarning message.
I use varargs frequently for constructors that can take some sort of filter object. For example, a large part of our system based on Hadoop is based on a Mapper that handles serialization and deserialization of items to JSON, and applies a number of processors that each take an item of content and either modify and return it, or return null to reject.
Another recommended exersice for understanding lists and indexes:
L = ['a', 'b', 'c']
for index, item in enumerate(L):
print index + '\n' + item
0
a
1
b
2
c
You can use the extension method AsEnumerable in Assembly System.Core and System.Linq namespace :
List<Book> list = new List<Book>();
return list.AsEnumerable();
This will, as said on this MSDN link change the type of the List in compile-time. This will give you the benefits also to only enumerate your collection we needed (see MSDN example for this).
Or you can use Stream API for 1 character or a String starting in Java 1.8:
public class ASCIIConversion {
public static void main(String[] args) {
String text = "adskjfhqewrilfgherqifvehwqfjklsdbnf";
text.chars()
.forEach(System.out::println);
}
}
I am running XAMPP 5.6.3-0 for OS X Yosemite 10.10.2 and ran into the same issue twice, the first time was with Mavericks. With a bunch of different solutions to the issue with MySQL Database not starting using Manager App I wanted to confirm what had worked for me. The workaround that always worked and forced MySQL to start was by opening Terminal and using: sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start I had the Manager App open and started ProFTPD and Apache and then ran the sudo command.
The other suggestion by wishap that worked was to locate /Applications/XAMPP/xamppfiles/etc/my.cnf file and change the permissions for "everyone" to Read only.
The other problem I had that seems to be another issue with many solutions is the problem after everything is started then entering localhost which brings me to the xampp splash screen and then nothing. The only thing that worked for me, to at the very least, to access the phpMyAdmin page is by entering localhost/phpmyadmin
I hope this helps others reading through a bunch of threads for an answer.

We have solved the same error by following the below steps.
linux command for this type of error occurred then, first of all, check your php.ini file
If your php.ini file exists then in configuration file simply uncomment the extension:
;extension=php_pdo_mysql.dll
Else follow below steps
step1:php -v
step2: Install php mysql extension
php 7.0 sudo apt-get install php7.0-mysql
php 7.1 sudo apt-get install php7.1-mysql
php 7.2 sudo apt-get install php7.2-mysql
php 7.3 sudo apt-get install php7.3-mysql
step3: service apache2 restart
step4: php artisan migrate
I also got the same error message of 'Unsupported major.minor version 52.0' when running ./gradlew makeJar to create a jar library by Android Studio 2.2.3.
After moving down the version of gradle plugin in build.gradle from 2.2.2 to 2.1.3, the error message disappeared and all worked well. classpath 'com.android.tools.build:gradle:2.1.3'
I don't know how the higer version of gradle plugin caused the error, but this did the trick for me. please let me know how this worked if you know the answer, thanks
Strange behaviour which I was experienced also. So for me "return false" did the trick.
$( '#selector' ).on( 'click', function() {

return false;
});
The Date
documentation states that :
The JavaScript date is based on a time value that is milliseconds since midnight January 1, 1970, UTC
Click on start button then on end button. It will show you the number of seconds between the 2 clicks.
The milliseconds diff is in variable timeDiff
. Play with it to find seconds/minutes/hours/ or what you need
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = new Date();_x000D_
};_x000D_

function end() {_x000D_
endTime = new Date();_x000D_
var timeDiff = endTime - startTime; //in ms_x000D_
// strip the ms_x000D_
timeDiff /= 1000;_x000D_

OR another way of doing it for modern browser
Using performance.now()
which returns a value representing the time elapsed since the time origin. This value is a double with microseconds in the fractional.
The time origin is a standard time which is considered to be the beginning of the current document's lifetime.

I've used DBDesigner before. It is an open source tool. You might check that out. Not sure if it fits your needs.
Best of luck!
In your trigger, you have two pseudo-tables available, Inserted
and Deleted
, which contain those values.
In the case of an UPDATE, the Deleted
table will contain the old values, while the Inserted
table contains the new values.
So if you want to log the ID, OldValue, NewValue
in your trigger, you'd need to write something like:
CREATE TRIGGER trgEmployeeUpdate
ON dbo.Employees AFTER UPDATE
AS
INSERT INTO dbo.LogTable(ID, OldValue, NewValue)
SELECT i.ID, d.Name, i.Name
FROM Inserted i
INNER JOIN Deleted d ON i.ID = d.ID
Basically, you join the Inserted
and Deleted
pseudo-tables, grab the ID (which is the same, I presume, in both cases), the old value from the Deleted
table, the new value from the Inserted
table, and you store everything in the LogTable
This should be your answer

Building on Allison and Deepak's answer, I started using logrus and really like it:
var log = logrus.New()
func init() {
// log to console and file
f, err := os.OpenFile("crawler.log", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)
if err != nil {
log.Fatalf("error opening file: %v", err)
}
wrt := io.MultiWriter(os.Stdout, f)
log.SetOutput(wrt)
}
I have a defer f.Close() in the main function
python manage.py migrate --fake APPNAME zero
This will make your migration to fake. Now you can run the migrate script
python manage.py migrate APPNAME
Tables will be created and you solved your problem.. Cheers!!!
I've seen a few different approaches to this, but I use a generic utility method as such:
public static T DeepClone<T>(this T obj)
{
using (var ms = new MemoryStream())
{
var formatter = new BinaryFormatter();
formatter.Serialize(ms, obj);
ms.Position = 0;
return (T) formatter.Deserialize(ms);
}
}
Notes:
[Serializable]
for this to work. Your source file must include the following code:
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
Note that this behaves the same on IIS 6 and 7.x, and .NET 2, 3, and 4.x.
Also note that when app_offline.htm is present, IIS will return this http status code:
HTTP/1.1 503 Service Unavailable
This is all by design. This allows your load balancer (or whatever) to see that the server is off line.
One is a static import (<%=@ include...>"), the other is a dynamic one (jsp:include). It will affect for example the path you gonna have to specify for your included file. A little research on Google will tell you more.
Yes, it is possible.
There is a perfect open-source Python (.PYC) decompiler, called Decompyle++ https://github.com/zrax/pycdc/
Decompyle++ aims to translate compiled Python byte-code back into valid and human-readable Python source code. While other projects have achieved this with varied success, Decompyle++ is unique in that it seeks to support byte-code from any version of Python.
First, install Python 3 pip using:
sudo apt-get install python3-pip
Then, to use Python 3 pip
use:
pip3 install <module-name>
For Python 2 pip
use:
pip install <module-name>
Select the labels above the bar. Format Data Labels. Instead of selecting "VALUE" (unclick). SELECT Value from cells. Select the value. Use the following statement: if(cellvalue="","",cellvalue) where cellvalue is what ever the calculation is in the cell.
The source code for ASP.NET AJAX is available for your reference, so you can pick through it and include the parts you want to continue using into a separate JS file. Or, you can port them to jQuery.
Here is the format function...
String.format = function() {
var s = arguments[0];
for (var i = 0; i < arguments.length - 1; i++) {
var reg = new RegExp("\\{" + i + "\\}", "gm");
s = s.replace(reg, arguments[i + 1]);
}
return s;
}
And here are the endsWith and startsWith prototype functions...
String.prototype.endsWith = function (suffix) {
return (this.substr(this.length - suffix.length) === suffix);
}
String.prototype.startsWith = function(prefix) {
return (this.substr(0, prefix.length) === prefix);
}
I don't believe this is possible, easily. The only way I believe to get around this is to make your own back button arrow image to place up there. It was frustrating for me at first but I see why, for consistency's sake, it was left out.
You can get close (without the arrow) by creating a regular button and hiding the default back button:
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Servers" style:UIBarButtonItemStyleDone target:nil action:nil] autorelease];
self.navigationItem.hidesBackButton = YES;
This solution works for me
var DELAY = 250, clicks = 0, timer = null;
$(".fc-event").click(function(e) {
if (timer == null) {
timer = setTimeout(function() {
clicks = 0;
timer = null;
// single click code
}, DELAY);
}
if(clicks === 1) {
clearTimeout(timer);
timer = null;
clicks = -1;
// double click code
}
clicks++;
});
Took some tooling around but this is what I ended up with.

To quickly find a meaningful error message by inspecting the error during debugging:
Add a quick watch for:
((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors
Drill down into EntityValidationErrors like this:
(collection item e.g. [0]) > ValidationErrors > (collection item e.g. [0]) > ErrorMessage
You should be able to do something like this in your respond_to
block:
respond_to do |format|
format.json
render :partial => "users/show.json"
end
which will render the template in app/views/users/_show.json.erb

The maximum result which will return by elasticSearch is 10000 by providing the size
curl -XGET 'localhost:9200/index/type/_search?scroll=1m' -d '
{
"size":10000,
"query" : {
"match_all" : {}
}
}'
After that, you have to use Scroll API for getting the result and get the _scroll_id value and put this value in scroll_id
curl -XGET 'localhost:9200/_search/scroll' -d'
{
"scroll" : "1m",
"scroll_id" : ""
}'
It specifies the size of the log file to trigger rotation. For example size 50M
will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M
for megabytes, k
for kilobytes, and G
for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size
, maxsize
, and minsize
. According to manpage:
minsize size
Log files are rotated when they grow bigger than size bytes,
but not before the additionally specified time interval (daily,
weekly, monthly, or yearly). The related size option is simi-
lar except that it is mutually exclusive with the time interval
options, and it causes log files to be rotated without regard
for the last rotation time. When minsize is used, both the
size and timestamp of a log file are considered.
size size
Log files are rotated only if they grow bigger then size bytes.
If size is followed by k, the size is assumed to be in kilo-
bytes. If the M is used, the size is in megabytes, and if G is
used, the size is in gigabytes. So size 100, size 100k, size
100M and size 100G are all valid.
maxsize size
Log files are rotated when they grow bigger than size bytes even before
the additionally specified time interval (daily, weekly, monthly,
or yearly). The related size option is similar except that it
is mutually exclusive with the time interval options, and it causes
log files to be rotated without regard for the last rotation time.
When maxsize is used, both the size and timestamp of a log file are
considered.
Here is an example:
"/var/log/httpd/access.log" /var/log/httpd/error.log {
rotate 5
mail [email protected]
size 100k
sharedscripts
postrotate
/usr/bin/killall -HUP httpd
endscript
}
Here is an explanation for both files /var/log/httpd/access.log
and /var/log/httpd/error.log
. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected]
after going through 5 rotations, rather than being removed. The sharedscripts
means that the postrotate
script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,
, and \
characters supported.
When onMeasure
is called the view gets its measured width/height. After this, you can call layout.getMeasuredHeight()
.
var count=0;
let myArray = '{"1":"a","2":"b","3":"c","4":"d"}'
var data = JSON.parse(myArray);
for (let key in data) {
let value = data[key]; // get the value by key
console.log("key: , value:", key, value);
count = count + 1;
}
console.log("size:",count);
The program is closing as soon as it's execution is complete. In this case when you return 0;
. This is expected functionality. If you want to see the output then either run it in a terminal manually or set a wait at the end of the program so that it will stay open for a few seconds ( using the threading library ).

With this, the console auto-complete fails silently while statements typed in console will fail to execute (the exception will be logged).

Just replace from bottom and add this
tv.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
before
llview.addView(tv);
node js and express 4 use this sequences
express = require('express');
var router = express.Router();
module.exports = router;
last line returns this type of error
// Edit: Tool was already mentioned in another answer, so give all credits to Kuryaki.
Just found SupoSE which is a java based command line tool which scans a repository to create an index and afterwards is able to answer certain kinds of queries. We're still evaluating the tool but it looks promising. It's worth to mention that it makes a full index of all revisions including source code files and common office formats.
There are multiple function to do this work that wrote in bottom based on priority.
Set one or more CSS properties for the set of matched elements.
$("div").css("display", "block")
// Or add multiple CSS properties
$("div").css({
display: "block",
color: "red",
...
})
Display the matched elements and is roughly equivalent to calling .css("display", "block")
You can display element using .show()
instead
$("div").show()
Set one or more attributes for the set of matched elements.
If target element hasn't style
attribute, you can use this method to add inline style to element.
$("div").attr("style", "display:block")
// Or add multiple CSS properties
$("div").attr("style", "display:block; color:red")
You can add specific CSS property to element using pure javascript, if you don't want to use jQuery.
var div = document.querySelector("div");
// One property
div.style.display = "block";
// Multiple properties
div.style.cssText = "display:block; color:red";
// Multiple properties
div.setAttribute("style", "display:block; color:red");
The answer to the question was already posted by the @latemail in the comments above. You can use regular expressions for the second and subsequent arguments of filter
like this:
dplyr::filter(df, !grepl("RTB",TrackingPixel))
Since you have not provided the original data, I will add a toy example using the mtcars
data set. Imagine you are only interested in cars produced by Mazda or Toyota.
mtcars$type <- rownames(mtcars)
dplyr::filter(mtcars, grepl('Toyota|Mazda', type))
mpg cyl disp hp drat wt qsec vs am gear carb type
1 21.0 6 160.0 110 3.90 2.620 16.46 0 1 4 4 Mazda RX4
2 21.0 6 160.0 110 3.90 2.875 17.02 0 1 4 4 Mazda RX4 Wag
3 33.9 4 71.1 65 4.22 1.835 19.90 1 1 4 1 Toyota Corolla
4 21.5 4 120.1 97 3.70 2.465 20.01 1 0 3 1 Toyota Corona
If you would like to do it the other way round, namely excluding Toyota and Mazda cars, the filter
command looks like this:
dplyr::filter(mtcars, !grepl('Toyota|Mazda', type))
when you need to send files through a specific SSH port:
rsync -azP -e "ssh -p PORT_NUMBER" source destination
example
rsync -azP -e "ssh -p 2121" /path/to/files/source user@remoteip:/path/to/files/destination
freqs = {}
for word in words:
freqs[word] = freqs.get(word, 0) + 1 # fetch and increment OR initialize
I think this results to the same as Triptych's solution, but without importing collections. Also a bit like Selinap's solution, but more readable imho. Almost identical to Thomas Weigel's solution, but without using Exceptions.
This could be slower than using defaultdict() from the collections library however. Since the value is fetched, incremented and then assigned again. Instead of just incremented. However using += might do just the same internally.
Wrap the code within $(document).ready(function(){...........});
handler , also remove the ;
after if
$(document).ready(function(){
$('#purpose').on('change', function() {
if ( this.value == '1')
//.....................^.......
{
$("#business").show();
}
else
{
$("#business").hide();
}
});
});
Answers from this thread with the highest upvotes didn't work for me as their hashing functions give different results on different machines due to PYTHOPYTHONHASHSEED
.
I adjusted all the hints from this thread and came up with a solution that works for me.
import collections
import hashlib
import json
def simplify_object(o):
if isinstance(o, dict):
ordered_dict = collections.OrderedDict(sorted(o.items()))
for k, v in ordered_dict.items():
v = simplify_object(v)
ordered_dict[str(k)] = v
o = ordered_dict
elif isinstance(o, (list, tuple, set)):
o = [simplify_object(el) for el in o]
else:
o = str(o).strip()
return o
def make_hash(o):
o = simplify_object(o)
bytes_val = json.dumps(o, sort_keys=True, ensure_ascii=True, default=str)
hash_val = hashlib.sha1(bytes_val.encode()).hexdigest()
return hash_val
