The following approach was inspired by this answer to a related (more general) question.
The approach is to read the MachineGuid
value in registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
. This value is generated during OS installation.
There are few ways around the uniqueness of the Hardware-ID per machine using this approach. One method is editing the registry value, but this would cause complications on the user's machine afterwards. Another method is to clone a drive image which would copy the MachineGuid
value.
However, no approach is hack-proof and this will certainly be good enough for normal users. On the plus side, this approach is quick performance-wise and simple to implement.
public string GetMachineGuid()
{
string location = @"SOFTWARE\Microsoft\Cryptography";
string name = "MachineGuid";
using (RegistryKey localMachineX64View =
RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
{
using (RegistryKey rk = localMachineX64View.OpenSubKey(location))
{
if (rk == null)
throw new KeyNotFoundException(
string.Format("Key Not Found: {0}", location));
object machineGuid = rk.GetValue(name);
if (machineGuid == null)
throw new IndexOutOfRangeException(
string.Format("Index Not Found: {0}", name));
return machineGuid.ToString();
}
}
}
Just ran into this. I'm getting over 6,000 records. Just decided I'd just do some paging. As in, I accept a page number in my MVC JsonResult endpoint, which is defaulted to 0 so it's not necessary, like so:
public JsonResult MyObjects(int pageNumber = 0)
Then instead of saying:
return Json(_repository.MyObjects.ToList(), JsonRequestBehavior.AllowGet);
I say:
return Json(_repository.MyObjects.OrderBy(obj => obj.ID).Skip(1000 * pageNumber).Take(1000).ToList(), JsonRequestBehavior.AllowGet);
It's very simple. Then, in JavaScript, instead of this:
function myAJAXCallback(items) {
// Do stuff here
}
I instead say:
var pageNumber = 0;
function myAJAXCallback(items) {
if(items.length == 1000)
// Call same endpoint but add this to the end: '?pageNumber=' + ++pageNumber
}
// Do stuff here
}
And append your records to whatever you were doing with them in the first place. Or just wait until all the calls finish and cobble the results together.
I updated BigGridDemo to support multiple sheets.

In my project I have Gradle task for integration test in sub-module:
task intTest(type: Test) {
...
system.properties System.properties
...
this is the main point to inject all your system params into test environment. So, now you can run gradle like this to pass param with ABC value and use its value by ${param} in your code
gradle :some-service:intTest -Dparam=ABC
You can use dateutil.parser.parse
(install with python -m pip install python-dateutil
) to parse strings into datetime objects.
dateutil.parser.parse
will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime
which you supply a format string to (see Brent Washburne's answer).
from dateutil.parser import parse
a = "2012-10-09T19:00:55Z"
b = parse(a)
print(b.weekday())
# 1 (equal to a Tuesday)
<html>
<head>
<script>
function updateTextarea(element)
{
document.getElementById(element).innerText = document.getElementById("ment").value;
}
</script>
</head>
<body>
<input type="text" value="Enter your text here." id = "ment" style = " border: 1px solid grey; margin-bottom: 4px;"
onKeyUp="updateTextarea('myDiv')" />
<br>
<textarea id="myDiv" ></textarea>

You should first pull
the changes from the develop
branch and only then merge them to your branch:
git checkout develop
git pull
git checkout branch-x
git rebase develop
Or, when on branch-x
:
git fetch && git rebase origin/develop
I have an alias that saves me a lot of time. Add to your ~/.gitconfig
:
[alias]
fr = "!f() { git fetch && git rebase origin/"$1"; }; f"
Now, all that you have to do is:
git fr develop
This isn't sufficient: the object returned by __iter__
must implement the iteration protocol (i.e. next
method). See the relevant section in the documentation.
In Python, a good practice is to "try and see" instead of "checking".
The repository is not down, it looks like they've changed how they host files (I guess they have restored some old code):
Now you have to add the /package-name/ before the -
Eg:
http://registry.npmjs.org/-/npm-1.1.48.tgz
http://registry.npmjs.org/npm/-/npm-1.1.48.tgz
There are 3 ways to solve it:
Use a public proxy:
--registry http://165.225.128.50:8000
Host a local proxy:
https://github.com/hughsk/npm-quickfix
git clone https://github.com/hughsk/npm-quickfix.git cd npm-quickfix npm set registry http://localhost:8080/ node index.js
I'd personally go with number 3 and revert to npm set registry http://registry.npmjs.org/
as soon as this get resolved.
Stay tuned here for more info: https://github.com/isaacs/npm/issues/2694
If you think about it, comparing numbers to logical statements doesn't make much sense. However, since 0 is often associated with "Off" or "False" and 1 with "On" or "True", R has decided to allow 1 == TRUE
and 0 == FALSE
to both be true. Any other numeric-to-boolean comparison should yield false, unless it's something like 3 - 2 == TRUE
.
Use:
AND oh.tran_date BETWEEN TRUNC(SYSDATE - 1) AND TRUNC(SYSDATE) - 1/86400
Reference: TRUNC
Calling a function on the tran_date
means the optimizer won't be able to use an index (assuming one exists) associated with it. Some databases, such as Oracle, support function based indexes which allow for performing functions on the data to minimize impact in such situations, but IME DBAs won't allow these. And I agree - they aren't really necessary in this instance.
Below Function converts the Excel sheet (XLSX format) data to JSON. you can add promise to the function.

var ExcelToJSON = function() {
this.parseExcel = function(file) {
var reader = new FileReader();
reader.onload = function(e) {
var data = e.target.result;
var workbook = XLSX.read(data, {
type: 'binary'
});
workbook.SheetNames.forEach(function(sheetName) {
// Here is your object
var XL_row_object = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
var json_object = JSON.stringify(XL_row_object);
console.log(json_object);
})
};
reader.onerror = function(ex) {
console.log(ex);
};
reader.readAsBinaryString(file);
};
};
</script>
Below post has the code for XLS format Excel to JSON javascript code?
Now I got it working (after removing the header
command). I think the problem was that the encoding of the php file was in ISO-8859-1. I set it to UTF-8 without BOM. I thought I already have done that, but perhaps I made an additional undo.
Furthermore, I used SET NAMES 'utf8'
for the database. Now it is also correct in the database.
If the array is multidimensional, this will work great:
//trims empty spaces in array elements (recursively trim multidimesional arrays)
function trimData($data){
if($data == null)
return null;
if(is_array($data)){
return array_map('trimData', $data);
}else return trim($data);
}
one sample test is like this:
$arr=[" aaa ", " b ", "m ", [" .e ", " 12 3", "9 0 0 0 "]];
print_r(trimData($arr));
//RESULT
//Array ( [0] => aaa [1] => b [2] => m [3] => Array ( [0] => .e [1] => 12 3 [2] => 9 0 0 0 ) )
Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...
So the solution was quite simple - I've just done this grant:
grant userB to userA;
That's all folks ;-)
Another requirement is that the object has to be owned by user userA before altering it...
It's usually best to handle the error locally rather than in a global signal event handler since locally you will have more context as to what's going on and what recourse to take.
I have a communication layer in one of my apps that allows my app to communicate with an external accessory. When a write error occurs I throw and exception in the communication layer and let it bubble up to a try catch block to handle it there.
The code to ignore a SIGPIPE signal so that you can handle it locally is:
// We expect write failures to occur but we want to handle them where
// the error occurs rather than in a SIGPIPE handler.
signal(SIGPIPE, SIG_IGN);
This code will prevent the SIGPIPE signal from being raised, but you will get a read / write error when trying to use the socket, so you will need to check for that.
in order to clean automatically .sock file, place these lines in file /etc/init.d/mysqld immediately after "start)" block of code
test -e /var/lib/mysql/mysql.sock
SOCKEXIST=$?
ps cax | grep mysqld_safe
NOPIDMYSQL=$?
echo NOPIDMYSQL $NOPIDMYSQL
echo SOCKEXIST $SOCKEXIST
if [ $NOPIDMYSQL -eq 1 ] && [ $SOCKEXIST -eq 0 ] ; then
echo "NOT CLEAN"
rm -f /var/lib/mysql/mysql.sock
echo "FILE SOCK REMOVED"
else
echo "CLEAN"
fi
it worked for me. I had to do this because I have not an UPS and often we have power supply failures.
regards.

One way to achieve this is to wrap the API call into a promise and then use await
to wait for the result.
// let's say this is the API function with two callbacks,
// one for success and the other for error
function apiFunction(query, successCallback, errorCallback) {
if (query == "bad query") {
errorCallback("problem with the query");
}
successCallback("Your query was <" + query + ">");
}
// myFunction wraps the above API call into a Promise
// and handles the callbacks with resolve and reject
function apiFunctionWrapper(query) {
return new Promise((resolve, reject) => {
apiFunction(query,(successResponse) => {
resolve(successResponse);
}, (errorResponse) => {
reject(errorResponse);
});
});
}
// now you can use await to get the result from the wrapped api function
// and you can use standard try-catch to handle the errors
async function businessLogic() {
try {
const result = await apiFunctionWrapper("query all users");
console.log(result);
// the next line will fail
const result2 = await apiFunctionWrapper("bad query");
} catch(error) {
console.error("ERROR:" + error);
}
}
// call the main function
businessLogic();
Output:
Your query was <query all users>
ERROR:problem with the query
When you use the java
command to run a Java application from the command line, e.g.,
java some.AppName arg1 arg2 ...
the command loads the class that you nominated and then looks for the entry point method called main
. More specifically, it is looking for a method that is declared as follows:
package some;
public class AppName {
...
public static void main(final String[] args) {
// body of main method follows
...
}
}
The specific requirements for the entry point method are:
public
.static
2.void
.String[]
3. (The argument may be declared using varargs
syntax; e.g. String... args
. See this question for more information. The String[]
argument is used to pass the arguments from the command line, and is required even if your application takes no command-line arguments.)
If anyone of the above requirements is not satisfied, the java
command will fail with some variant of the message:
Error: Main method not found in class MyClass, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
Or, if you are running an extremely old version of Java:
java.lang.NoSuchMethodError: main
Exception in thread "main"
If you encounter this error, check that you have a main
method and that it satisfies all of the six requirements listed above.
1 - One really obscure variation of this is when one or more of the characters in "main" is NOT a LATIN-1 character … but a Unicode character that looks like the corresponding LATIN-1 character when displayed.
2 - Here is an explanation of why the method is required to be static.
3 - String
must correspond to java.lang.String
and not to a custom class named String
hiding it.
You're not getting an "invalid date" error. Rather, the value of temp is "Invalid Date".
Is your date string in a valid format? If you're using Firefox, check Date.parse
In Firefox javascript console:
>>> Date.parse("2010-08-17 12:09:36");
NaN
>>> Date.parse("Aug 9, 1995")
807944400000
I would try a different date string format.
Zebi, are you using Internet Explorer?
If you're using Java 9, there's an easy way with less number of lines without needing to initialize or add
method.
List<String> list = List.of("first", "second", "third");
Although MSDN says that "s" and "o" formats reflect the standard, they seem to be able to parse only a limited subset of it. Especially it is a problem if the string contains time zone specification. (Neither it does for basic ISO8601 formats, or reduced precision formats - however this is not exactly your case.) That is why I make use of custom format strings when it comes to parsing ISO8601. Currently my preferred snippet is:
static readonly string[] formats = {
// Basic formats
"yyyyMMddTHHmmsszzz",
"yyyyMMddTHHmmsszz",
"yyyyMMddTHHmmssZ",
// Extended formats
"yyyy-MM-ddTHH:mm:sszzz",
"yyyy-MM-ddTHH:mm:sszz",
"yyyy-MM-ddTHH:mm:ssZ",
// All of the above with reduced accuracy
"yyyyMMddTHHmmzzz",
"yyyyMMddTHHmmzz",
"yyyyMMddTHHmmZ",
"yyyy-MM-ddTHH:mmzzz",
"yyyy-MM-ddTHH:mmzz",
"yyyy-MM-ddTHH:mmZ",
// Accuracy reduced to hours
"yyyyMMddTHHzzz",
"yyyyMMddTHHzz",
"yyyyMMddTHHZ",
"yyyy-MM-ddTHHzzz",
"yyyy-MM-ddTHHzz",
"yyyy-MM-ddTHHZ"
};
public static DateTime ParseISO8601String ( string str )
{
return DateTime.ParseExact ( str, formats,
CultureInfo.InvariantCulture, DateTimeStyles.None );
}
If you don't mind parsing TZ-less strings (I do), you can add an "s" line to greatly extend the number of covered format alterations.
I fixed it reinstalling the jdk. In my case it was necessary to do:
java -version
sudo apt-get purge openjdk*
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
java -version
javac -version

AlphaAnimation animation1 = new AlphaAnimation(0.2f, 1.0f);
animation1.setDuration(1000);
animation1.setStartOffset(5000);
animation1.setFillAfter(true);
iv.startAnimation(animation1);
No, they don't exist.
I know that the C# team was considering them at one point (or at least Eric Lippert was) - along with extension constructors and operators (those may take a while to get your head around, but are cool...) However, I haven't seen any evidence that they'll be part of C# 4.
EDIT: They didn't appear in C# 5, and as of July 2014 it doesn't look like it's going to be in C# 6 either.
Eric Lippert, the Principal Developer on the C# compiler team at Microsoft thru November 2012, blogged about this in October of 2009:
The most easiest way is to convert it into an integer. For example #bce6eb. You would add 0xff and you would then remove the hashtag making it
0xffbce6eb
Then lets say you were to implement it by doing
backgroundColor: Color(0xffbce6eb)
If you can only use a hexadecimal then I suggest using the Hexcolor package https://pub.dev/packages/hexcolor
INSERT INTO vendors (
name,
phone,

The 2019 optimal solution for this is HTTP/2 Server Push.
You do not need any hacky javascript solutions or inline styles. However, you do need a server that supports HTTP 2.0 (any modern server version will), which itself requires your server to run SSL. However, with Let's Encrypt there's no reason not to be using SSL anyway.
My site https://r.je/ has a 100/100 score for both mobile and desktop.
The reason for these errors is that the browser gets the HTML, then has to wait for the CSS to be downloaded before the page can be rendered. Using HTTP2 you can send both the HTML and the CSS at the same time.
You can use HTTP/2 push by setting the Link header.
Apache example (.htaccess):
Header add Link "</style.css>; as=style; rel=preload, </font.css>; as=style; rel=preload"
For NGINX you can add the header to your location tag in the server configuration:
location = / {
add_header Link "</style.css>; as=style; rel=preload, </font.css>; as=style; rel=preload";
}
With this header set, the browser receives the HTML and CSS at the same time which stops the CSS from blocking rendering.
You will want to tweak it so that the CSS is only sent on the first request, but the Link header is the most complete and least hacky solution to "Eliminate Render Blocking Javascript and CSS"
For a detailed discussion, take a look at my post here: Eliminate Render Blocking CSS using HTTP/2 Push
unique_ptr doesn't have the traditional copy constructor. Instead it has a "move constructor" that uses rvalue references:
unique_ptr::unique_ptr(unique_ptr && src);
An rvalue reference (the double ampersand) will only bind to an rvalue. That's why you get an error when you try to pass an lvalue unique_ptr to a function. On the other hand, a value that is returned from a function is treated as an rvalue, so the move constructor is called automatically.
By the way, this will work correctly:
bar(unique_ptr<int>(new int(44));
The temporary unique_ptr here is an rvalue.
The simplest way is to use the following pattern:
http://[server]/[site]/[ListName]/[Folder]/[SubFolder]
To place a shortcut to a document library:
timer.cancel(); //Terminates this timer,discarding any currently scheduled tasks.
timer.purge(); // Removes all cancelled tasks from this timer's task queue.
A very simple way to read an external script into an sqlite database in python is using executescript()
:
import sqlite3
conn = sqlite3.connect('csc455_HW3.db')
with open('ZooDatabase.sql', 'r') as sql_file:
conn.executescript(sql_file.read())
conn.close()
sudo
command not found
to check whether the sudo package is installed on your system, type sudo
, and press Enter . If you have sudo
installed the system will display a short help message, otherwise you will see something like sudo: command not found
To install sudo, run one of the following commands using root account:
apt-get install sudo
# If your system based on apt package manager

Do you want to do this?
SELECT id, parent_id, name,
(select Name from tbl where id = t.parent_id) parent_name
FROM tbl t start with id = 1 CONNECT BY PRIOR id = parent_id
Edit Another option based on OMG's one (but I think that will perform equally):
select
t1.id,
t1.parent_id,
t1.name,
t2.name AS parent_name,
t2.id AS parent_id
from
(select id, parent_id, name
from tbl
start with id = 1
connect by prior id = parent_id) t1
left join
tbl t2 on t2.id = t1.parent_id
For limited set of values matplotlib is fine. But when you have lots of values the tooltip starts to overlap over other data points. But with limited space you can't ignore the values. Hence it's better to zoom out or zoom in.
Using plotly
import plotly.express as px
df = px.data.tips()
df = px.data.gapminder().query("year==2007 and continent=='Americas'")
fig = px.scatter(df, x="gdpPercap", y="lifeExp", text="country", log_x=True, size_max=100, color="lifeExp")
fig.update_traces(textposition='top center')
fig.update_layout(title_text='Life Expectency', title_x=0.5)

I believe some of the respondents of this question have missed the broader implication of the fold
function as an abstract tool. Yes, sum
can do the same thing for a list of integers, but this is a trivial case. fold
is more generic. It is useful when you have a sequence of data structures of varying shape and want to cleanly express an aggregation. So instead of having to build up a for
loop with an aggregate variable and manually recompute it each time, a fold
function (or the Python version, which reduce
appears to correspond to) allows the programmer to express the intent of the aggregation much more plainly by simply providing two things:
Here a single line Solution:
((LinearLayout.LayoutParams) yourLinearLayout.getLayoutParams()).marginToAdd = ((int)(Resources.getSystem().getDisplayMetrics().density * yourDPValue));
No plugins or mappings required. Try the built-in "norm" command, which literally executes anything you want on every selected line.
Add # Comments
1. shift V to visually select lines
2. :norm i#
Remove # Comments
1. visually select region as before
2. :norm x
Or if your comments are indented you can do :norm ^x
Notice that these are just ordinary vim commands being preceded by ":norm" to execute them on each line.
More detailed answer for using "norm" command in one of the answers here
Xamarin port of Felix's answer
In your MainActivity
, add this (docs: Android.App.IntentFilterAttribute Class):
....
[IntentFilter(new[] {
Intent.ActionView },
Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
DataScheme = "my.special.scheme")
]
public class MainActivity : Activity
{
....
Xamarin will add following in the AndroidManifest.xml
for you:
<activity
android:label="Something"
android:screenOrientation="portrait"
android:theme="@style/MyTheme"
android:name="blah.MainActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="my.special.scheme" />
</intent-filter>
</activity>
And in order to get params (I tested in OnCreate of MainActivity):
var data = Intent.Data;
if (data != null)
{
var scheme = data.Scheme;
var host = data.Host;
var args = data.PathSegments;
if (args.Count > 0)
{
var first = args[0];
var second = args[1];
...
}
}
As far as I know, above can be added in any activity, not only MainActivity
Notes:
OnCreate
event of app's MainLauncher Activity
will be fired again.<a href="my.special.scheme://host/arg1/arg2">
, in above last code snippet values will be:scheme: my.special.scheme
host: host
args: ["arg1", "arg2"]
first: arg1
second: arg2
Update: if android creates new instance of your app, you should add android:launchMode="singleTask"
too.
simple is the best and works in every version.
if a>10:
value="b"
else:
value="c"
Note, you can use {{.}}
to render the current context item.
{{#avatar}}{{.}}{{/avatar}}
{{^avatar}}missing{{/avatar}}
I don't think converting to a tuple is the right answer. You need go and look at where you are calling the function and make sure that c
is a list of list of strings, or whatever you designed this function to work with
For example you might get this error if you passed [c]
to the function instead of c
use the full-featured .ajax
jQuery function.
compare with https://stackoverflow.com/a/3543713/1689451 for an example.
without testing, just merging your code with the referenced SO question:
target = $(this).attr('data-target');
$.ajax({
url: $(this).attr('href'),
type: "GET",
timeout: 2000,
success: function(response) { $(target).modal({
show: true
}); },
error: function(x, t, m) {
if(t==="timeout") {
alert("got timeout");
} else {
alert(t);
}
}
});?
The compiler only knows that the type of "a" is Animal
; this happens at compile time, because of which it is called static binding (Method overloading). But if it is dynamic binding then it would call the Dog
class method. Here is an example of dynamic binding.
public class DynamicBindingTest {
public static void main(String args[]) {
Animal a= new Dog(); //here Type is Animal but object will be Dog
a.eat(); //Dog's eat called because eat() is overridden method
}
}
class Animal {
public void eat() {
System.out.println("Inside eat method of Animal");
}
}
class Dog extends Animal {
@Override
public void eat() {
System.out.println("Inside eat method of Dog");
}
}
Output: Inside eat method of Dog
Like this:
keys = ['a', 'b', 'c']
values = [1, 2, 3]
dictionary = dict(zip(keys, values))
print(dictionary) # {'a': 1, 'b': 2, 'c': 3}
Voila :-) The pairwise dict
constructor and zip
function are awesomely useful.
Having said, I'd rather see developers build kick-ass apps that are well-designed and follow separation of concerns, than see them waste time arguing about MV* nonsense. And for this reason, I hereby declare AngularJS to be MVW framework - Model-View-Whatever. Where Whatever stands for "whatever works for you".

You need to provide a candidate for autowire. That means that an instance of PasswordHint must be known to spring in a way that it can guess that it must reference it.
Please provide the class head of PasswordHint and/or the spring bean definition of that class for further assistance.
Try changing the name of
PasswordHintAction action;
to
PasswordHintAction passwordHintAction;
so that it matches the bean definition.

You can read about the keyword unsigned in the C++ Reference.
There are two different types in this matter, signed and un-signed. The default for integers is signed which means that they can have negative values.
On a 32-bit system an integer is 32 Bit which means it can contain a value of ~4 billion.
And when it is signed, this means you need to split it, leaving -2 billion to +2 billion.
When it is unsigned however the value cannot contain any negative numbers, so for integers this would mean 0 to +4 billion.
There is a bit more informationa bout this on Wikipedia.
Dark magic function incantation for those who want the find ... xargs ... head ...
solution above, but in easy to use function form so you don't have to think:
#define the function
find_newest_file_matching_pattern_under_directory(){
echo $(find $1 -name $2 -print0 | xargs -0 ls -1 -t | head -1)
}
#setup:
#mkdir /tmp/files_to_move
#cd /tmp/files_to_move
#touch file1.txt
#touch file2.txt
#invoke the function:
newest_file=$( find_newest_file_matching_pattern_under_directory /tmp/files_to_move/ bc* )
echo $newest_file
Prints:
file2.txt
Which is:
The filename with the oldest modified timestamp of the file under the given directory matching the given pattern.
Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.
For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

The short answer is no: MySQL does not allow you to add a WHERE
clause to the TRUNCATE
statement. Here's MySQL's documentation about the TRUNCATE
statement.
But the good news is that you can (somewhat) work around this limitation.
Simple, safe, clean but slow solution using DELETE
First of all, if the table is small enough, simply use the DELETE
statement (it had to be mentioned):
1. LOCK TABLE my_table WRITE;
2. DELETE FROM my_table WHERE my_date<DATE_SUB(NOW(), INTERVAL 1 MONTH);
3. UNLOCK TABLES;
The LOCK
and UNLOCK
statements are not compulsory, but they will speed things up and avoid potential deadlocks.
Unfortunately, this will be very slow if your table is large... and since you are considering using the TRUNCATE
statement, I suppose it's because your table is large.
So here's one way to solve your problem using the TRUNCATE
statement:
Simple, fast, but unsafe solution using TRUNCATE
1. CREATE TABLE my_table_backup AS
SELECT * FROM my_table WHERE my_date>=DATE_SUB(NOW(), INTERVAL 1 MONTH);
2. TRUNCATE my_table;
3. LOCK TABLE my_table WRITE, my_table_backup WRITE;
4. INSERT INTO my_table SELECT * FROM my_table_backup;
5. UNLOCK TABLES;
6. DROP TABLE my_table_backup;
Unfortunately, this solution is a bit unsafe if other processes are inserting records in the table at the same time:
TRUNCATE
statement resets the AUTO-INCREMENT
counter to zero. So any record inserted between steps 2 and 3 will have an ID that will be lower than older IDs and that might even conflict with IDs inserted at step 4 (note that the AUTO-INCREMENT
counter will be back to it's proper value after step 4).Unfortunately, it is not possible to lock the table and truncate it. But we can (somehow) work around that limitation using RENAME
.
Half-simple, fast, safe but noisy solution using TRUNCATE
1. RENAME TABLE my_table TO my_table_work;
2. CREATE TABLE my_table_backup AS
SELECT * FROM my_table_work WHERE my_date>DATE_SUB(NOW(), INTERVAL 1 MONTH);
3. TRUNCATE my_table_work;
4. LOCK TABLE my_table_work WRITE, my_table_backup WRITE;
5. INSERT INTO my_table_work SELECT * FROM my_table_backup;
6. UNLOCK TABLES;
7. RENAME TABLE my_table_work TO my_table;
8. DROP TABLE my_table_backup;
This should be completely safe and quite fast. The only problem is that other processes will see table my_table
disappear for a few seconds. This might lead to errors being displayed in logs everywhere. So it's a safe solution, but it's "noisy".
Disclaimer: I am not a MySQL expert, so these solutions might actually be crappy. The only guarantee I can offer is that they work fine for me. If some expert can comment on these solutions, I would be grateful.
You can use the following code to add column to Datatable at postion 0:
DataColumn Col = datatable.Columns.Add("Column Name", System.Type.GetType("System.Boolean"));
Col.SetOrdinal(0);// to put the column in position 0;
@Bryce, really nice answer.
VB.NET version:
Public Shared Iterator Function FindVisualChildren(Of T As DependencyObject)(depObj As DependencyObject) As IEnumerable(Of T)
If depObj IsNot Nothing Then
For i As Integer = 0 To VisualTreeHelper.GetChildrenCount(depObj) - 1
Dim child As DependencyObject = VisualTreeHelper.GetChild(depObj, i)
If child IsNot Nothing AndAlso TypeOf child Is T Then
Yield DirectCast(child, T)
End If
For Each childOfChild As T In FindVisualChildren(Of T)(child)
Yield childOfChild
Next
Next
End If
End Function
Usage (this disables all TextBoxes in a window):
For Each tb As TextBox In FindVisualChildren(Of TextBox)(Me)
tb.IsEnabled = False
Next
There is a new open-source effort to develop a Java library for push notifications on Android, using the Meteor comet server as a backend. You can check it out at the Deacon Project Blog. We need developers, so please spread the word!
You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).
See http://api.jquery.com/on/#direct-and-delegated-events
Change your code to
$(document.body).on('click', '.update' ,function(){
The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live
, the jQuery set elements must exist when you execute the code.
As this answers receives a lot of attention, here are two supplementary advises :
1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.
That is, if you're adding an element of class b
to an existing element of id a
, then don't use
$(document.body).on('click', '#a .b', function(){
but use
$('#a').on('click', '.b', function(){
2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c"
would retrieve only one element with this id.
First of all we will need serializeObject();
$.fn.serializeObject = function () {
var o = {};
var a = this.serializeArray();
$.each(a, function () {
if (o[this.name]) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
then you make a basic post and get response
$.post("/Education/StudentSave", $("#frmNewStudent").serializeObject(), function (data) {
if(data){
//do true
}
else
{
//do false
}
});
Ctrl + F12 did not work for me, nor did Home, PageUp etc.
So here's what finally came up with:
NUMLOCK
;also using http://php.net/error_get_last will not help you out, because mail() does not emmit its errors into this function.
Only way seems to be using a proper mailer, like already suggested above.
When I ran taskkill to stop the javaw.exe process it would say it had terminated but remained running. The jqs process (java qucikstart) needs to be stopped also. Running this batch file took care of the issue.
taskkill /f /im jqs.exe

taskkill /f /im java.exe
Try this one with array_reverse()
.
$arr = array(
'first' => 01,
'second' => 10,
'third' => 20,
);
$key = key(array_reverse($arr));
var_dump($key);
this seems to work as wel ->
@Override
public List<SomeObject> findAllForThisSpecificThing(String thing) {
final Query query = entityManager.createQuery(
"from " + getDomain().getSimpleName() + " t where t.thing = " + ((thing == null) ? " null" : " :thing"));
if (thing != null) {
query.setParameter("thing", thing);
}
return query.getResultList();
}
Btw, I'm pretty new at this, so if for any reason this isn't a good idea, let me know. Thanks.
if anyone has a problem on Mac, can try this

This is what helped me. My navigation bar is in the body tag. Entire code for navigation bar is in nav.html
file (without any html or body tag, only the code for navigation bar). In the target page, this goes in the head
tag:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Then in the body tag, a container is made with an unique id and a javascript block to load the nav.html
into the container, as follows:
<!--Navigation bar-->
<div id="nav-placeholder">
</div>
<script>
$(function(){
$("#nav-placeholder").load("nav.html");
});
</script>
<!--end of Navigation bar-->
That's no problem.
@Html.Partial("../Controller/View", model)
or
@Html.Partial("~/Views/Controller/View.cshtml", model)
Should do the trick.
If you want to pass through the (other) controller, you can use:
@Html.Action("action", "controller", parameters)
or any of the other overloads
If is a package then you can get the source for that with:
select text from all_source where name = 'PADCAMPAIGN'
and type = 'PACKAGE BODY'
order by line;
Oracle doesn't store the source for a sub-program separately, so you need to look through the package source for it.
Note: I've assumed you didn't use double-quotes when creating that package, but if you did , then use
select text from all_source where name = 'pAdCampaign'
and type = 'PACKAGE BODY'
order by line;
@Nicolai is correct about casting and why the condition is false for any data. i guess you prefer the first form because you want to avoid date manipulation on the input string, correct? you don't need to be afraid:
SELECT *
FROM table
WHERE update_date >= '2013-05-03'::date
AND update_date < ('2013-05-03'::date + '1 day'::interval);
If you need more control (perhaps you need to state the table name) you can also do the following:
Model.joins(:another_model_table_name)
.where('another_model_table_name.id IN (?)', your_id_array)
Certainly not the only way - you could prototype a method (against Object here but I certainly wouldn't suggest using Object for live code) to replicate C#/Java style comparison methods.
Edit, since a general example seems to be expected:
Object.prototype.equals = function(x)
{
for(p in this)
{
switch(typeof(this[p]))
{
case 'object':
if (!this[p].equals(x[p])) { return false }; break;
case 'function':
if (typeof(x[p])=='undefined' || (p != 'equals' && this[p].toString() != x[p].toString())) { return false; }; break;
default:
if (this[p] != x[p]) { return false; }
}
}
for(p in x)
{
if(typeof(this[p])=='undefined') {return false;}
}
return true;
}
Note that testing methods with toString() is absolutely not good enough but a method which would be acceptable is very hard because of the problem of whitespace having meaning or not, never mind synonym methods and methods producing the same result with different implementations. And the problems of prototyping against Object in general.
As you can see from the error message the paths, that you specified, are wrong. Try it like this:
activate ..\..\temp\venv\test
However, when I needed to install Anaconda, I downloaded it from here and installed it to the default paths (C:\Anaconda
), than I put this path to the environment variables, so now Anacondas interpreter is used as default. If you are using PyCharm, for example, you can specify the interpreter there directly.

Starting from a byte array you can use the binary package to do the conversions.
For example if you want to read ints :
buf := bytes.NewBuffer(b) // b is []byte
myfirstint, err := binary.ReadVarint(buf)
anotherint, err := binary.ReadVarint(buf)
The same package allows the reading of unsigned int or floats, with the desired byte orders, using the general Read function.
An example of Python's way of doing "ternary" expressions:
i = 5 if a > 7 else 0
translates into
if a > 7:
i = 5
else:
i = 0
This actually comes in handy when using list comprehensions, or sometimes in return statements, otherwise I'm not sure it helps that much in creating readable code.
The readability issue was discussed at length in this recent SO question better way than using if-else statement in python.
It also contains various other clever (and somewhat obfuscated) ways to accomplish the same task. It's worth a read just based on those posts.
To convert it to a single dictionary with some decided keys value, you can use the code below.
data = ListOfDict.copy()
PrecedingText = "Obs_"
ListOfDictAsDict = {}
for i in range(len(data)):
ListOfDictAsDict[PrecedingText + str(i)] = data[i]

With modern versions of curl, you can simply override which ip-address to connect to, using --resolve or --connect-to (curl newer than version 7.49). This works even with SSL/SNI. All details are in the man page.
For example, to override DNS and connect to www.example.com with ssl using a particular ip address: (This will also override ipv6)
curl --resolve www.example.com:443:192.168.42.2 https://www.example.com/
Another example, to connect to a particular backend server named backend1 on port 8080
curl --connect-to www.example.com:80:backend1.example.com:8080 http://www.example.com/
Remember to add the host header if the server needs that to answer correctly:
-H 'Host:www.example.com'

The best solution is toString
(as stated above):
function getRealObjectType(obj: {}): string {
return Object.prototype.toString.call(obj).match(/\[\w+ (\w+)\]/)[1].toLowerCase();
}
FAIR WARNING: toString
considers NaN
a number
so you must manually safeguard later with Number.isNaN(value)
.
The other solution suggested, using Object.getPrototypeOf
fails with null
and undefined
public static void main(final String[] argv)
{
String str;
str = "hello\r\n\tjava\r\nbook";
str = str.replaceAll("(\\r|\\n|\\t)", "");
System.out.println(str);
}
It would be useful to add the tabulation in regex too.
Using Base64 string in JSON will be very heavy. The parser has to do a lot of heavy lifting. Currently, Fresco only supports base supports Base64. Better you put something on Amazon Cloud or Firebase Cloud. And get an image as a URL. So that you can use Picasso or Glide for caching.
moment startOf() and endOf() is the answer you are searching for.. For Example:-
moment().startOf('year'); // set to January 1st, 12:00 am this year
moment().startOf('month'); // set to the first of this month, 12:00 am
moment().startOf('week'); // set to the first day of this week, 12:00 am
moment().startOf('day'); // set to 12:00 am today
Simple! Create a dummy database (say abc)
Copy all these .myd, .myi, .frm files to mysql\data\abc wherein mysql\data\ is the place where .myd, .myi, .frm for all databases are stored.
Then go to phpMyadmin, go to db abc and you find your database.
Given that the accepted answer is outdated and I see nothing in the other answers regarding this I am creating a new one. In .Net 2, and earlier, you had to manually close the stream before closing the connection. That bug is fixed in all later versions of TcpClient
in C# and as stated in the doc of the Close method a call to the method Close
closes both the connection and the stream
EDIT according to Microsoft Docs
The Close method marks the instance as disposed and requests that the associated Socket close the TCP connection. Based on the LingerState property, the TCP connection may stay open for some time after the Close method is called when data remains to be sent. There is no notification provided when the underlying connection has completed closing.
Calling this method will eventually result in the close of the associated Socket and will also close the associated NetworkStream that is used to send and receive data if one was created.
In Python 3 the dict.values()
method returns a dictionary view object, not a list like it does in Python 2. Dictionary views have a length, can be iterated, and support membership testing, but don't support indexing.
To make your code work in both versions, you could use either of these:
{names[i]:value for i,value in enumerate(d.values())}
or
values = list(d.values())
{name:values[i] for i,name in enumerate(names)}
By far the simplest, fastest way to do the same thing in either version would be:
dict(zip(names, d.values()))
Note however, that all of these methods will give you results that will vary depending on the actual contents of d
. To overcome that, you may be able use an OrderedDict instead, which remembers the order that keys were first inserted into it, so you can count on the order of what is returned by the values()
method.
If you want to compact/repair an external mdb file (not the one you are working in just now):
Application.compactRepair sourecFile, destinationFile
If you want to compact the database you are working with:
Application.SetOption "Auto compact", True
In this last case, your app will be compacted when closing the file.
My opinion: writting a few lines of code in an extra MDB "compacter" file that you can call when you want to compact/repair an mdb file is very usefull: in most situations the file that needs to be compacted cannot be opened normally anymore, so you need to call the method from outside the file.
Otherwise, the autocompact shall by default be set to true in each main module of an Access app.
In case of a disaster, create a new mdb file and import all objects from the buggy file. You will usually find a faulty object (form, module, etc) that you will not be able to import.
Objects does not support push property, but you can save it as well using the index as key,
var tempData = {};_x000D_
for ( var index in data ) {_x000D_
if ( data[index].Status == "Valid" ) { _x000D_
tempData[index] = data; _x000D_
} _x000D_
}_x000D_
data = tempData;
_x000D_
I think this is easier if remove the object if its status is invalid, by doing.
for(var index in data){_x000D_
if(data[index].Status == "Invalid"){ _x000D_
delete data[index]; _x000D_
} _x000D_
}
_x000D_
And finally you don't need to create a var temp –
There is obviously another process listening on the port. You might find out that process by using the following command:
$ lsof -i :8000
or change your tornado app's port. tornado's error info not Explicitly on this.
Here are several benefits of IHttpActionResult
over HttpResponseMessage
mentioned in Microsoft ASP.Net Documentation:
- Simplifies unit testing your controllers.
- Moves common logic for creating HTTP responses into separate classes.
- Makes the intent of the controller action clearer, by hiding the low-level details of constructing the response.
But here are some other advantages of using IHttpActionResult
worth mentioning:
Ok
NotFound
Exception
Unauthorized
BadRequest
Conflict
Redirect
InvalidModelState
(link to full list)ExecuteAsync
method.ResponseMessageResult ResponseMessage(HttpResponseMessage response)
to convert HttpResponseMessage to IHttpActionResult.WebDriver driver=new FirefoxDriver();
driver.get("http://www.java-examples.com/java-string-examples");
Thread.sleep(3000);
//Switch to nested frame
driver.switchTo().frame("aswift_2").switchTo().frame("google_ads_frame3");
You don't have the namespace the Login class is in as a reference.
Add the following to the form that uses the Login
class:
using FootballLeagueSystem;
When you want to use a class in another namespace, you have to tell the compiler where to find it. In this case, Login
is inside the FootballLeagueSystem
namespace, or : FootballLeagueSystem.Login
is the fully qualified namespace.
As a commenter pointed out, you declare the Login class inside the FootballLeagueSystem
namespace, but you're using it in the FootballLeague
namespace.
Typing the following in the terminal will erase your history (meaning using up arrow will get you nothing), but it will not clear the screen:

You can just do a regular postback to refresh the page if you don't want to redirect. Posting back from any control will run the page lifecycle and refresh the page.
To do it from javascript, you can just call the __doPostBack() function.
A work-around is to use @tvanfosson's answer (the selected answer) and use JQuery (or Javascript) to set the option's value to 0:
$(document).ready(function () {
$('#DropDownListId option:first').val('0');
});
Hope this helps.
In Clean Code, Robert C. Martin devoted four pages to the subject. Here's the gist:
The ideal number of arguments for a function is zero (niladic). Next comes one (monadic), followed closely by two (dyadic). Three arguments (triadic) should be avoided where possible. More than three (polyadic) requires very special justification -- and then shouldn't be used anyway.
You can use margin for .wrap container instead of padding for .wrapper:
body{ height:20000px }
#wrapper { padding: 0%; }
#wrap{
float: left;
position: relative;
margin: 10%;
width: 40%;
background:#ccc;
}
#fixed{
position:fixed;
width:inherit;
padding:0px;
height:10px;
background-color:#333;
}
After having the same issue, I got confused with all the answers here and the comments over the repository of sass in github.
I just want to point out that as December 2014, this issue has been resolved. It is now possible to import css
files directly into your sass file. The following PR in github solves the issue.
The syntax is the same as now - @import "your/path/to/the/file"
, without an extension after the file name. This will import your file directly. If you append *.css
at the end, it will translate into the css
rule @import url(...)
.
In case you are using some of the "fancy" new module bundlers such as webpack, you will probably need to use use ~
in the beginning of the path. So, if you want to import the following path node_modules/bootstrap/src/core.scss
you would write something like @import "~bootstrap/src/core"
.
NOTE:
It appears this isn't working for everybody. If your interpreter is based on libsass
it should be working fine (checkout this). I've tested using @import
on node-sass and it's working fine. Unfortunately this works and doesn't work on some ruby instances.
Client-side validation was not being executed at all on my web form and I had no idea why. It turns out the problem was the name of the javascript function was the same as the server control ID.
So you can't do this...
<script>
function vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="vld" />
But this works:
<script>
function validate_vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="validate_vld" />
I'm guessing it conflicts with internal .NET Javascript?
In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}
, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.
This is helpful when your equals method call throws some exception e.g. NullPointerException
;
boolean isMatch = false;
try{
isMatch = email1.equals (email2);
}catch(NullPointerException npe){
.....
}
System.out.print("Match=="+isMatch);
if(isMatch){
......
}
Expanding upon Melu's answer you can do this to functionalize the code and handle negative amounts.
Sample Output:
$5.23
-$5.23
function formatCurrency(total) {
var neg = false;
if(total < 0) {
neg = true;
total = Math.abs(total);
}
return (neg ? "-$" : '$') + parseFloat(total, 10).toFixed(2).replace(/(\d)(?=(\d{3})+\.)/g, "$1,").toString();
}
When submitting a form, you tell your browser to send, via the HTTP protocol, a message on the network, properly enveloped in a TCP/IP protocol message structure. An HTML page has a way to send data to the server: by using <form>
s.
When a form is submitted, an HTTP Request is created and sent to the server, the message will contain the field names in the form and the values filled in by the user. This transmission can happen with POST
or GET
HTTP methods.
POST
tells your browser to build an HTTP message and put all content in the body of the message (a very useful way of doing things, more safe and also flexible).GET
will submit the form data in the querystring. It has some constraints about data representation and length.Attribute enctype
has sense only when using POST
method. When specified, it instructs the browser to send the form by encoding its content in a specific way. From MDN - Form enctype:
When the value of the method attribute is post, enctype is the MIME type of content that is used to submit the form to the server.
application/x-www-form-urlencoded
: This is the default. When the form is sent, all names and values are collected and URL Encoding is performed on the final string.multipart/form-data
: Characters are NOT encoded. This is important when the form has a file upload control. You want to send the file binary and this ensures that bitstream is not altered.text/plain
: Spaces get converted, but no more encoding is performed.When submitting forms, some security concerns can arise as stated in RFC 7578 Section 7: Multipart form data - Security considerations:
All form-processing software should treat user supplied form-data
with sensitivity, as it often contains confidential or personally
identifying information. There is widespread use of form "auto-fill" features in web browsers; these might be used to trick users to
unknowingly send confidential information when completing otherwise
innocuous tasks. multipart/form-data does not supply any features
for checking integrity, ensuring confidentiality, avoiding user
confusion, or other security features; those concerns must be
addressed by the form-filling and form-data-interpreting applications.Applications that receive forms and process them must be careful not to supply data back to the requesting form-processing site that was not intended to be sent.
It is important when interpreting the filename of the Content-
Disposition header field to not inadvertently overwrite files in the
recipient's file space.
This concerns you if you are a developer and your server will process forms submitted by users which might end up containing sensitive information.
def window(seq, size, step=1):
# initialize iterators
iters = [iter(seq) for i in range(size)]
# stagger iterators (without yielding)
[next(iters[i]) for j in range(size) for i in range(-1, -j-1, -1)]
while(True):
yield [next(i) for i in iters]
# next line does nothing for step = 1 (skips iterations for step > 1)
[next(i) for i in iters for j in range(step-1)]
next(it)
raises StopIteration
when the sequence is finished, and for some cool reason that's beyond me, the yield statement here excepts it and the function returns, ignoring the leftover values that don't form a full window.
Anyway, this is the least-lines solution yet whose only requirement is that seq
implement either __iter__
or __getitem__
and doesn't rely on itertools
or collections
besides @dansalmo's solution :)
If you are running puppet it may set /proc/sys/kernel/modules_disabled
to 1, inhibiting further module loading.
When the machine is reboot, it gets set back to 0, allowing for changes, such as loading the iptables modules. After a certain amount of time puppet will set it back to 1 to protect the system from kernel root kits.
Therefore, whatever modules that we are going to need should be loaded during or shortly after boot time.
Note that ord()
doesn't give you the ASCII value per se; it gives you the numeric value of the character in whatever encoding it's in. Therefore the result of ord('ä')
can be 228 if you're using Latin-1, or it can raise a TypeError
if you're using UTF-8. It can even return the Unicode codepoint instead if you pass it a unicode:
>>> ord(u'?')

The Maximally Standards Compliant way to do it is to create a text node containing the text you want and append it to the span (removing any currently extant text nodes).
The way I would actually do it is to use jQuery's .text()

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
If you're geting [object object]
then use JSON.stringify

var _t = new Date();
if you want UTC format simply
_t.toLocaleString('indian', { timeZone: 'UTC' }).replace(/(\w+)\/(\w+)\/(\w+), (\w+)/, '$3-$2-$1 $4');
or
_t.toISOString().slice(0, 19).replace('T', ' ');
and if want in specific timezone then
_t.toLocaleString('indian', { timeZone: 'asia/kolkata' }).replace(/(\w+)\/(\w+)\/(\w+), (\w+)/, '$3-$2-$1 $4');
When you import lib
, you're importing the package. The only file to get evaluated and run in this case is the 0 byte __init__.py
in the lib directory.
If you want access to your function, you can do something like this from lib.mod1 import mod1
and then run the mod12
function like so mod1.mod12()
.
If you want to be able to access mod1
when you import lib
, you need to put an import mod1
inside the __init__.py
file inside the lib
directory.

The previous posts about forming POST
requests are largely correct (add the parameters to the body, not the URL). But if there is any chance of the input data containing any reserved characters (e.g. spaces, ampersand, plus sign), then you will want to handle these reserved characters. Namely, you should percent-escape the input.
//create body of the request
NSString *userid = ...
NSString *encodedUserid = [self percentEscapeString:userid];
NSString *postString = [NSString stringWithFormat:@"userid=%@", encodedUserid];
NSData *postBody = [postString dataUsingEncoding:NSUTF8StringEncoding];
//initialize a request from url
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPBody:postBody];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
//initialize a connection from request, any way you want to, e.g.
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
Where the precentEscapeString
method is defined as follows:
- (NSString *)percentEscapeString:(NSString *)string
{
NSString *result = CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,
(CFStringRef)string,
(CFStringRef)@" ",
(CFStringRef)@":/?@!$&'()*+,;=",
kCFStringEncodingUTF8));
return [result stringByReplacingOccurrencesOfString:@" " withString:@"+"];
}
Note, there was a promising NSString
method, stringByAddingPercentEscapesUsingEncoding
(now deprecated), that does something very similar, but resist the temptation to use that. It handles some characters (e.g. the space character), but not some of the others (e.g. the +
or &
characters).
The contemporary equivalent is stringByAddingPercentEncodingWithAllowedCharacters
, but, again, don't be tempted to use URLQueryAllowedCharacterSet
, as that also allows +
and &
pass unescaped. Those two characters are permitted within the broader "query", but if those characters appear within a value within a query, they must escaped. Technically, you can either use URLQueryAllowedCharacterSet
to build a mutable character set and remove a few of the characters that they've included in there, or build your own character set from scratch.
For example, if you look at Alamofire's parameter encoding, they take URLQueryAllowedCharacterSet
and then remove generalDelimitersToEncode
(which includes the characters #
, [
, ]
, and @
, but because of a historical bug in some old web servers, neither ?
nor /
) and subDelimitersToEncode
(i.e. !
, $
, &
, '
, (
, )
, *
, +
, ,
, ;
, and =
). This is correct implementation (though you could debate the removal of ?
and /
), though pretty convoluted. Perhaps CFURLCreateStringByAddingPercentEscapes
is more direct/efficient.

To search the whole computer:
gdr -PSProvider 'FileSystem' | %{ ls -r $.root} 2>$null | where { $.name -eq "httpd.exe" }
I am pretty sure this is a much less efficient command, for MANY reasons, but the simplest is your piping everything to your where-object command, when you could still use -filter "httpd.exe" and save a ton of cycles.
Also, on a lot of computers the get-psdrive is gonna grab shared drives, and I am pretty sure you wanted that to get a complete search. Most shares can be IMMENSE with regard to the sheer number of files and folders, so at the very least I would sort my drives by size, and add a check after each search to exit the loop if we locate the file. That is if you are looking for a single instance, if not the only way to save yourself the IMMENSE time sink of searching a 10TB share or two, is to comment the command and highly suggest any user who were to need to use it should limit their search as much as they can. For instance our User Profile share is 10TB, at least the one I am on is, and I can limit my search to the directory $sharedrive\users\myname and search my 116GB directory rather than the 10TB one. Too many unknowns with shares for this type of script, which is already super inefficient with regard to resources and speed.
If I was seriously considering using something like this, I would add a call to a 3rd party package and leverage a DB.
When you specify position:absolute it positions itself to the next-highest element with position:relative. In this case, that's the .project div.
If you give the image's immediate parent div a style of position:relative, the overlay will key to that instead of the div which includes the text. For example: http://jsfiddle.net/7gYUU/1/
<div class="parent">
<img src="http://placehold.it/500x500" class="img-responsive"/>
<div class="fa fa-plus project-overlay"></div>
</div>
.parent {
position: relative;

In the interest of actually putting a working solution to this question:

Obviously, you could change the NOW() function to any date or variable you want.
Since you're already using numpy
, it makes sense to store your data in a numpy
array rather than a list. Once you do this, you get things like element-wise products for free:
In [1]: import numpy as np

In [3]: b = np.array([2,3,4,5])
In [4]: a * b
Out[4]: array([ 2, 6, 12, 20])

Why am I not returning a "Toyota" value? Because the "Toyota" choice in the Selection Box would have already returned "2", which, would indicate that the selected Manufacturer in the Selection Box would be Toyota.
How would the user know if the value is equal to the Toyota selection in the Selection Box? In between my example code's brackets, you would put $maker = "Toyota"
then echo $maker
, or create a new string, like so: $maketwo = "Toyota"
then you can echo $makertwo
(I much prefer creating a new string, rather than overwriting $maker
's original value.)
If the user selects "Nissan", will the example code take care of that as well..? Yes, and no. While "Toyota" would return value "2", "Nissan" would instead return value "3". The current set value that the example code is looking for is "2", which means that if the user selects "Nissan", which represents value "3", then presses "Search", the example code would not be executed. You can easily change the code to check for value "3", or value "1", which represents "--Any--".
What if the user clicks "Search" while the Selection Box is set to "Select Manufacturer"? How can I prevent them from doing so? To prevent them from proceeding any further, change the set value of the example code to "0", and in between the brackets, you may place your code, then after that, add return;
, which terminates all execution of any further code within the function / statement.
You can use phpseclib pollyfill package. You can not use open ssl or libsodium for encrypt/decrypt with rijndael 256. Another issue, you don't need replacement any code.
You can install this Jenkins Console log plugin to write the log in your workspace as a post build step.
You have to build the plugin yourself and install the plugin manually.
Next, you can add a post build step like that:
With an additional post build step (shell script), you will be able to grep your log.
I hope it helped :)
Append Length
A 64-bit representation of b (the length of the message before the padding bits were added) is appended to the result of the previous step. In the unlikely event that b is greater than 2^64, then only the low-order 64 bits of b are used.

Based on some of the above answers I created a MoneyTextWatcher which you'd use as follows:
priceEditText.addTextChangedListener(new MoneyTextWatcher(priceEditText));
and here's the class:
public class MoneyTextWatcher implements TextWatcher {
private final WeakReference<EditText> editTextWeakReference;
public MoneyTextWatcher(EditText editText) {
editTextWeakReference = new WeakReference<EditText>(editText);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable editable) {
EditText editText = editTextWeakReference.get();
if (editText == null) return;
String s = editable.toString();
if (s.isEmpty()) return;
editText.removeTextChangedListener(this);
String cleanString = s.replaceAll("[$,.]", "");
BigDecimal parsed = new BigDecimal(cleanString).setScale(2, BigDecimal.ROUND_FLOOR).divide(new BigDecimal(100), BigDecimal.ROUND_FLOOR);
String formatted = NumberFormat.getCurrencyInstance().format(parsed);
editText.setText(formatted);
editText.setSelection(formatted.length());
editText.addTextChangedListener(this);
}
}
Use These two lines to your EditText
android:imeActionLabel="Done"
android:singleLine="true"
or you can achieve it Programmatically by this line.
editText.setImeOptions(EditorInfo.IME_ACTION_DONE);
Just specifying HTTPS in the URI should do the trick.
httpClient.BaseAddress = new Uri("https://foobar.com/");
If the request works with HTTP but fails with HTTPS then this is most certainly a certificate issue. Make sure the caller trusts the certificate issuer and that the certificate is not expired. A quick and easy way to check that is to try making the query in a browser.
You also may want to check on the server (if it's yours and / or if you can) that it is set to serve HTTPS requests properly.
Ah, got it myselfs.
The quirks and quarks of LINQ-2-entities.
This looks most understandable:
var query2 = (
from users in Repo.T_Benutzer
from mappings in Repo.T_Benutzer_Benutzergruppen
.Where(mapping => mapping.BEBG_BE == users.BE_ID).DefaultIfEmpty()
from groups in Repo.T_Benutzergruppen
.Where(gruppe => gruppe.ID == mappings.BEBG_BG).DefaultIfEmpty()
//where users.BE_Name.Contains(keyword)
// //|| mappings.BEBG_BE.Equals(666)
//|| mappings.BEBG_BE == 666
//|| groups.Name.Contains(keyword)
select new
{
UserId = users.BE_ID
,UserName = users.BE_User
,UserGroupId = mappings.BEBG_BG
,GroupName = groups.Name
}
);
var xy = (query2).ToList();
Remove the .DefaultIfEmpty()
, and you get an inner join.
That was what I was looking for.
There is a difference between signed and unsigned APK files. Most likely you had an unsigned on there previously. You just need to delete the unsigned before you install the signed version. How this can be accomplished varies on the exact version, but in general, go on the emulator to settings-> application, long click your app, and delete/remove/uninstall it.
You have to get the files length to append in JS and then send it via AJAX request as below
//JavaScript
var ins = document.getElementById('fileToUpload').files.length;
for (var x = 0; x < ins; x++) {
fd.append("fileToUpload[]", document.getElementById('fileToUpload').files[x]);
}
//PHP
$count = count($_FILES['fileToUpload']['name']);
for ($i = 0; $i < $count; $i++) {
echo 'Name: '.$_FILES['fileToUpload']['name'][$i].'<br/>';
}
Don’t need to specify a type
value of “text/css”
Every time you link to a CSS file:
<link rel="stylesheet" type="text/css" href="file.css">
You can simply write:
<link rel="stylesheet" href="file.css">
I try dismis progress on method onPageFinished(), but not good too much, it has time delay to render webview.
try with onPageCommitVisible() better:
val progressBar = ProgressDialog(context)
progressBar.setCancelable(false)
progressBar.show()
val url = "your url here"
web_container.settings.javaScriptEnabled = true
web_container.loadUrl(url)
web_container.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
view.loadUrl(url)
progressBar.show()
return true
}
override fun onPageFinished(view: WebView?, url: String?) {
super.onPageFinished(view, url)
}
override fun onPageCommitVisible(view: WebView?, url: String?) {
super.onPageCommitVisible(view, url)
progressBar.dismiss()
}
}
web_container.setOnKeyListener(View.OnKeyListener { _, keyCode, event ->
if (keyCode == KEYCODE_BACK && event.action == MotionEvent.ACTION_UP
&& web_container.canGoBack()) {
web_container.goBack()
return@OnKeyListener true
}
return@OnKeyListener false
})
Try this
<script type="text/javascript">
function AddItem()
{
// Create an Option object
var opt = document.createElement("option");
// Assign text and value to Option object
opt.text = "New Value";
opt.value = "New Value";
// Add an Option object to Drop Down List Box
document.getElementById('<%=DropDownList.ClientID%>').options.add(opt);
}
<script />
The Value will append to the drop down list.
if you are on Windows
sqlplus / as sysdba
Now you are logged with SYS user and you can do anything you want (query DBA_USERS to find out your username, or change any user password). You can not see the old password, you can only change it.
Problems only surface when I am I trying to give the first loaded content an active state
Does this mean that you want to add a class to the first button?
$('.o-links').click(function(e) { // ... }).first().addClass('O_Nav_Current');
instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:
CSS:
.image-area { width: 100%; height: auto; display: none; } .image-area:first-of-type { display: block; }
JavaScript:
var $slides = $('.image-area'), $btns = $('a.o-links'); $btns.on('click', function (e) { var i = $btns.removeClass('O_Nav_Current').index(this); $(this).addClass('O_Nav_Current'); $slides.filter(':visible').fadeOut(1000, function () { $slides.eq(i).fadeIn(1000); }); e.preventDefault(); }).first().addClass('O_Nav_Current');
In my case I was running under a different user than the one I was expecting.
I had 'DRIVER={SQL Server};SERVER=...;DATABASE=...;Trusted_Connection=false;User Id=XXX;Password=YYY'
as the connection string I passed to pypyodbc.connect()
, but the connection was still using the credentials of the Windows user that ran the script (I verified this using the SQL Server Profiler and by trying an invalid uid/password combination - which didn't result in an expected error).
I decided not to dig into this further, since switching to this better way of connecting fixed the issue:
conn = pypyodbc.connect(driver='{SQL Server}', server='servername', database='dbname', uid='userName', pwd='Password')
This bash script is for N parallel threads. Each argument is a command.
trap
will kill all subprocesses when SIGINT is catched.
wait $PID_LIST
is waiting each process to complete.
When all processes have completed, the program exits.
#!/bin/bash
for cmd in "$@"; do {
echo "Process \"$cmd\" started";
$cmd & pid=$!
PID_LIST+=" $pid";
} done
trap "kill $PID_LIST" SIGINT
echo "Parallel processes have started";
wait $PID_LIST
echo
echo "All processes have completed";
Save this script as parallel_commands
and make it executable.
This is how to use this script:
parallel_commands "cmd arg0 arg1 arg2" "other_cmd arg0 arg2 arg3"
Example:
parallel_commands "sleep 1" "sleep 2" "sleep 3" "sleep 4"
Start 4 parallel sleep and waits until "sleep 4" finishes.
var b bytes.Buffer

// b.String()
I had this problem when trying to delete a certain group of records (using MS Access 2007 with an ODBC connection to MySQL on a web server). Typically I would delete certain records from MySQL then replace with updated records (cascade delete several related records, this streamlines deleting all related records for a single record deletion).
I tried to run through the operations available in phpMyAdmin for the table (optimize,flush, etc), but I was getting a need permission to RELOAD error when I tried to flush. Since my database is on a web server, I couldn't restart the database. Restoring from a backup was not an option.
I tried running delete query for this group of records on the cPanel mySQL access on the web. Got same error message.
My solution: I used Sun's (Oracle's) free MySQL Query Browser (that I previously installed on my computer) and ran the delete query there. It worked right away, Problem solved. I was then able to once again perform the function using the Access script using the ODBC Access to MySQL connection.
It looks like you can add it to your ~/.my.cnf, but it needs to be added as an argument to the init-command flag in your [client] section, like so:
[client]
init-command='set autocommit=0'
Some receivers expect EOL sequence, which is typically two characters \r\n
, so try in your code replace the line
unsigned char cmd[] = {'I', 'N', 'I', 'T', ' ', '\r', '\0'};
with
unsigned char cmd[] = "INIT\r\n";
BTW, the above way is probably more efficient. There is no need to quote every character.
This is the job for style
property:
document.getElementById("remember").style.visibility = "visible";
Finally after several hours of investigation I think I have another solution for everyone having issues with AVD Manager "Unable to locate adb".
I know we have the setting for the SDK in File -> Settings -> Appearance & Behavior -> System Settings -> Android SDK. This it seems is not enough! It appears that Android Studio (at least the new version 4) does not give projects a default SDK, despite the above setting.
So, you also (for each project) need to go to File -> Project Structure -> Project Settings -> Project, and select the Project SDK, which is set to [No SDK] by default.
If there's nothing in the drop-down box, then select New, select Android SDK, and navigate to your Android SDK location (normally C:\Users[username]\AppData\Local\Android\Sdk on Windows). You will then be able to select the Android API xx Platform. You now should not get this annoying adb error.

A better way would be to use Stopwatch, instead of DateTime
differences.
Stopwatch Class - Microsoft Docs
Provides a set of methods and properties that you can use to accurately measure elapsed time.
Stopwatch stopwatch = Stopwatch.StartNew(); //creates and start the instance of Stopwatch
//your sample code
System.Threading.Thread.Sleep(500);
stopwatch.Stop();
Console.WriteLine(stopwatch.ElapsedMilliseconds);
You say you want to sort by value, but you don't have that in your code. Pass a lambda (or method reference) to sorted
to tell it how you want to sort.
And you want to get the keys; use map
to transform entries to keys.
List<Type> types = countByType.entrySet().stream()
.sorted(Comparator.comparing(Map.Entry::getValue))
.map(Map.Entry::getKey)
.collect(Collectors.toList());
What you also should consider, is keeping a reference to the created element, then you can easily remove it specificly:
var newUL = $('<ul><li>test</li></ul>');
$(this).append(newUL);
// Later ...
newUL.remove();
By default, Log4j
logs to standard output and that means you should be able to see log messages on your Eclipse's console view. To log to a file you need to use a FileAppender
explicitly by defining it in a log4j.properties
file in your classpath.
Create the following log4j.properties
file in your classpath. This allows you to log your message to both a file as well as your console.
log4j.rootLogger=debug, stdout, file
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=example.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%p %t %c - %m%n
Note: The above creates an example.log in your current working directory (i.e. Eclipse's project directory) so that the same log4j.properties could work with different projects without overwriting each other's logs.

Apache log4j 1.2 - Short introduction to log4j
Quick solution, relies on the -webkit-mask-image
property. -webkit-mask-image
sets a mask image for an element.
There are a few gotchas with this method:
:after
psuedo-element (IMG
tags can't have :before
/:after
pseudo elements, grr)attr(…)
CSS function to get the IMG
tag URL, so it's hard-coded into the CSS separately.If you can look past those issues, this might be a possible solution. SVG filters will be even more flexible, and Canvas solutions will be even more flexible and have a wider range of support (SVG doesn't have Android 2.x support).
VBA subs are no macros. A VBA sub can be a macro, but it is not a must.
The term "macro" is only used for recorded user actions. from these actions a code is generated and stored in a sub. This code is simple and do not provide powerful structures like loops, for example Do .. until, for .. next, while.. do, and others.
The more elegant way is, to design and write your own VBA code without using the macro features!
VBA is a object based and event oriented language. Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.
If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx.exe".
In VBA you have nothing like this, but you have a XLSM file wich is started by Excel. You can attach some code to the Workbook_Open event. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets.
It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.
In the object based model you have objects, that have events and methods. methods are action you can do with a object. events are things that can happen to an object. An objects can contain another objects, and so on. You can create new objects, like sheets or charts.
Although other answers prove the requirement, they don't explain why the requirement exists.
The JLS mentions why in §15.27.2:
The restriction to effectively final variables prohibits access to dynamically-changing local variables, whose capture would likely introduce concurrency problems.
To lower risk of bugs, they decided to ensure captured variables are never mutated.
The variable pCv is of type VARCHAR2 so when you concat the insert you aren't putting it inside single quotes:
EXECUTE IMMEDIATE 'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('''||pCv||''', '||pSup||', '||pIdM||')';
Additionally the error ORA-06512 raise when you are trying to insert a value too large in a column. Check the definiton of the table M_pNum_GR and the parameters that you are sending. Just for clarify if you try to insert the value 100 on a NUMERIC(2) field the error will raise.
For folks who ended up here and are using CYGWIN
, install following packages in cygwin and re-run:
In shell you assign to a variable without the dollar-sign:
TEST=`pwd`
echo $TEST
that's better (and can be nested) but is not as portable as the backtics:
TEST=$(pwd)
echo $TEST
Always remember: the dollar-sign is only used when reading a variable.
Code:
if(preg_match('/[^a-z_\-0-9]/i', $string))
{
echo "not valid string";
}
Explanation:
The 'i' modifier at the end of the regex is for 'case-insensitive' if you don't put that you will need to add the upper case characters in the code before by doing A-Z
If you want to use the catch()
of the Observable
you need to use Observable.throw()
method before delegating the error response to a method

worked for me
how about
echo $list | grep -w -q $x
you could either check the output or $?
of above line to make the decision.
grep -w
checks on whole word patterns. Adding -q
prevents echoing the list.
You can if your processor is 64-bit and Virtualization Technology (VT) extension is enabled (it can be switched off in BIOS). You can't do it on 32-bit processor.
To check this under Linux you just need to look into /proc/cpuinfo file. Just look for the appropriate flag (vmx for Intel processor or svm for AMD processor)
egrep '(vmx|svm)' /proc/cpuinfo
To check this under Windows you need to use a program like CPU-Z which will display your processor architecture and supported extensions.
Try this
.nav.navbar-nav.navbar-right li a span{
color: blue;
}
If it doesn't work try this
.nav.navbar-nav.navbar-right li a {
color: blue;
}
I have 2 accounts on my windows machine and I was experiencing this problem with one of them. I did not want to use the sa
account, I wanted to use Windows login. It was not immediately obvious to me that I needed to simply sign into the other account that I used to install SQL Server, and add the permissions for the new account from there
(SSMS > Security > Logins > Add a login there)
Easy way to get the full domain name you need to add there open cmd echo each one.
echo %userdomain%\%username%
Add a login for that user and give it all the permissons for master db and other databases you want. When I say "all permissions" make sure NOT to check of any of the "deny" permissions since that will do the opposite.
Type this in your terminal
xcode-select --install
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -license accept
You can just specify the python version when running a program:
for python 2:
python filename.py
for python 3:

From Laravel 6, Now It's working with the following command:
composer create-project --prefer-dist laravel/laravel:^7.0 blog
This is the proper one, select2 will clear the selected value and show the placeholder back .
$remote.select2('data', null)
I'd suggest that the -i
means it does match "ABC", but the difference is in the output. -i
doesn't manipulate the input, so it won't change "ABC" to "abc" because you specified "abc" as the pattern. -o
says it only shows the part of the output that matches the pattern specified, it doesn't say about matching input.
The output of echo "ABC" | grep -i abc
is ABC
, the -o
shows output matching "abc" so nothing shows:
Naos:~ mattlacey$ echo "ABC" | grep -i abc | grep -o abc
Naos:~ mattlacey$ echo "ABC" | grep -i abc | grep -o ABC
ABC
Sometimes that problem occurs if you already have a branch with the base name.
I tried this:
git checkout -b features/aName origin/features/aName
Unfortunately, I already had a branch named features
, and I got the exception of the question asker.
Removing the branch features
resolved the problem, the above command worked.
I totally missed the export button at the bottom of each visualization. As for read only access...Shield from Elasticsearch might be worth exploring.

Per the current docs, https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html:
If you’re providing text file input to curl, you must use the --data-binary flag instead of plain -d. The latter doesn’t preserve newlines.
Example:
$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests
converting object id to string(using toString() method) will do the job.
