More cleaner way using LINQ
var lines = dictionary.Select(kvp => kvp.Key + ": " + kvp.Value.ToString());
textBox3.Text = string.Join(Environment.NewLine, lines);
Retrieving the day of the week's number is dramatically simplified in Swift 3 because DateComponents
is no longer optional. Here it is as an extension:
extension Date {
func dayNumberOfWeek() -> Int? {
return Calendar.current.dateComponents([.weekday], from: self).weekday
}
}
// returns an integer from 1 - 7, with 1 being Sunday and 7 being Saturday
print(Date().dayNumberOfWeek()!) // 4
If you were looking for the written, localized version of the day of week:
extension Date {
func dayOfWeek() -> String? {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE"
return dateFormatter.string(from: self).capitalized
// or use capitalized(with: locale) if you want
}
}
print(Date().dayOfWeek()!) // Wednesday
One line Swift 5.2
let date = String(DateFormatter.localizedString(from: NSDate() as Date, dateStyle: .medium, timeStyle: .short))
Using SelectionRange
you will get the Start
and End
date.
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
var startDate = monthCalendar1.SelectionRange.Start.ToString("dd MMM yyyy");
var endDate = monthCalendar1.SelectionRange.End.ToString("dd MMM yyyy");
}
If you want to update the maximum number of days that can be selected, then set MaxSelectionCount
property. The default is 7.
// Only allow 21 days to be selected at the same time.
monthCalendar1.MaxSelectionCount = 21;
Also, I've noticed at different places and at different times the asterisk (
*
) is located either right after the timeNSDate* now
or right before the variableNSDate *now
. What is the difference in the two and why would you use one versus the other?
The compiler doesn't care, but putting the asterisk before the space can be misleading. Here's my example:
int* a, b;
What is the type of b
?
If you guessed int *
, you're wrong. It's just int
.
The other way makes this slightly clearer by keeping the * next to the variable it belongs to:
int *a, b;
Of course, there are two ways that are even clearer than that:
int b, *a;
int *a;
int b;
This should be equivalent to your current code, only a lot faster:
output <- matrix(unlist(z), ncol = 10, byrow = TRUE)
Beside all this, There is also a scenario where this error occures-
When you or your library project define custom attribute int attr.xml, And you use these attributes in your layout file without defining namespace .
Generally we use this namespace definition in header of our layout file.
xmlns:android="http://schemas.android.com/apk/res/android"
Then make sure all attributes in your file shoud start with
android:ATTRIBUTE-NAME
You need to identfy if some of your attirbute is not starting with something other than android:ATTRIBUTE-NAME like
temp:ATTRIBUTE-NAME
In this case you have this "temp" also as namespace, generally by including-
xmlns:temp="http://schemas.android.com/apk/res-auto"
The following should work and is my recommendation (parameterized query):
DateTime dateTimeVariable = //some DateTime value, e.g. DateTime.Now;
SqlCommand cmd = new SqlCommand("INSERT INTO <table> (<column>) VALUES (@value)", connection);
cmd.Parameters.AddWithValue("@value", dateTimeVariable);
cmd.ExecuteNonQuery();
#FFFFEEE
is not a correct color code. Try with #FFFFEE
instead.
I just release my latest library for Google Maps Direction API on Android https://github.com/akexorcist/Android-GoogleDirectionLibrary
For the convenience of usage, I sum up the note of striping punctuation from a string in both Python 2 and Python 3. Please refer to other answers for the detailed description.
Python 2
import string
s = "string. With. Punctuation?"
table = string.maketrans("","")
new_s = s.translate(table, string.punctuation) # Output: string without punctuation
Python 3
import string
s = "string. With. Punctuation?"
table = str.maketrans(dict.fromkeys(string.punctuation)) # OR {key: None for key in string.punctuation}
new_s = s.translate(table) # Output: string without punctuation
As others have pointed out, you can combine find
and basename
, but by default the basename
program will only operate on one path at a time, so the executable will have to be launched once for each path (using either find ... -exec
or find ... | xargs -n 1
), which may potentially be slow.
If you use the -a
option on basename
, then it can accept multiple filenames in a single invocation, which means that you can then use xargs
without the -n 1
, to group the paths together into a far smaller number of invocations of basename
, which should be more efficient.
Example:
find /dir1 -type f -print0 | xargs -0 basename -a
Here I've included the -print0
and -0
(which should be used together), in order to cope with any whitespace inside the names of files and directories.
Here is a timing comparison, between the xargs basename -a
and xargs -n1 basename
versions. (For sake of a like-with-like comparison, the timings reported here are after an initial dummy run, so that they are both done after the file metadata has already been copied to I/O cache.) I have piped the output to cksum
in both cases, just to demonstrate that the output is independent of the method used.
$ time sh -c 'find /usr/lib -type f -print0 | xargs -0 basename -a | cksum'
2532163462 546663
real 0m0.063s
user 0m0.058s
sys 0m0.040s
$ time sh -c 'find /usr/lib -type f -print0 | xargs -0 -n 1 basename | cksum'
2532163462 546663
real 0m14.504s
user 0m12.474s
sys 0m3.109s
As you can see, it really is substantially faster to avoid launching basename
every time.
On a Windows PC, use an older version of Chrome and the command will work for all you guys. I downgraded my Chrome to 26 version and it worked.
Just like this:
string s="AbcdEf";
if(s.ToLower().Contains("def"))
{
Console.WriteLine("yes");
}
For *Unix based systems, you can check the ports used by a particular application by issueing the following command in the terminal
[~/.]$ netstat -tuplen
You will get the list of all the ports that are being currently held and used by their respective process ID's
$.each(result, function(key, value) {
console.log(key+ ':' + value);
});
Here is the code to convert one zone DateTime
to another zone DateTime
DECLARE @UTCDateTime DATETIME = GETUTCDATE();
DECLARE @ConvertedZoneDateTime DATETIME;
-- 'UTC' to 'India Standard Time' DATETIME
SET @ConvertedZoneDateTime = @UTCDateTime AT TIME ZONE 'UTC' AT TIME ZONE 'India Standard Time'
SELECT @UTCDateTime AS UTCDATE,@ConvertedZoneDateTime AS IndiaStandardTime
-- 'India Standard Time' to 'UTC' DATETIME
SET @UTCDateTime = @ConvertedZoneDateTime AT TIME ZONE 'India Standard Time' AT TIME ZONE 'UTC'
SELECT @ConvertedZoneDateTime AS IndiaStandardTime,@UTCDateTime AS UTCDATE
Note: AT TIME ZONE
works only on SQL Server 2016+ and the advantage is that it automatically considers Daylight when converting to a particular Time zone
For Mac, run the below command in a terminal window:
echo export "PATH=$HOME/Library/Python/2.7/bin:$PATH"
This worked for me when I got the same error message...
mvn install deploy
There simply is no console listening by default. Running in debug mode there is a console attached, but in a production environment it is as you suspected, the message just doesn't go anywhere because nothing is listening.
You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:
public class ProgramViwer : Form{
public ProgramViwer()
{
InitializeComponent();
Load += new EventHandler(ProgramViwer_Load);
}
private void ProgramViwer_Load(object sender, System.EventArgs e)
{
formPanel.Controls.Clear();
formPanel.Controls.Add(wel);
}
}
You had several issues with your code.
1) Missing a closing brace, }
, within your rules
.
2) In this case, there is no reason to use a function for the required
rule. By default, the plugin can handle checkbox
and radio
inputs just fine, so using true
is enough. However, this will simply do the same logic as in your original function and verify that at least one is checked.
3) If you also want only a maximum of two to be checked, then you'll need to apply the maxlength
rule.
4) The messages
option was missing the rule specification. It will work, but the one custom message would apply to all rules on the same field.
5) If a name
attribute contains brackets, you must enclose it within quotes.
DEMO: http://jsfiddle.net/K6Wvk/
$(document).ready(function () {
$('#formid').validate({ // initialize the plugin
rules: {
'test[]': {
required: true,
maxlength: 2
}
},
messages: {
'test[]': {
required: "You must check at least 1 box",
maxlength: "Check no more than {0} boxes"
}
}
});
});
Well, technically '\0'
is a character while "\0"
is a string, so if you're checking for the null termination character the former is correct. However, as Chris Lutz points out in his answer, your comparison won't work in it's current form.

Since Marco's answer is deprecated, you must use the following syntax (according jasonlfunk's comment) :
$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'http://www.example.com/user/create', [
'form_params' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
]
]);
$response = $client->request('POST', 'http://www.example.com/files/post', [
'multipart' => [
[
'name' => 'file_name',
'contents' => fopen('/path/to/file', 'r')
],
[
'name' => 'csv_header',
'contents' => 'First Name, Last Name, Username',
'filename' => 'csv_header.csv'
]
]
]);
// PUT
$client->put('http://www.example.com/user/4', [
'body' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
],
'timeout' => 5
]);
// DELETE
$client->delete('http://www.example.com/user');
Usefull for long server operations.
$client = new \GuzzleHttp\Client();
$promise = $client->requestAsync('POST', 'http://www.example.com/user/create', [
'form_params' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
]
]);
$promise->then(
function (ResponseInterface $res) {
echo $res->getStatusCode() . "\n";
},
function (RequestException $e) {
echo $e->getMessage() . "\n";
echo $e->getRequest()->getMethod();
}
);
According to documentation, you can set headers :
// Set various headers on a request
$client->request('GET', '/get', [
'headers' => [
'User-Agent' => 'testing/1.0',
'Accept' => 'application/json',
'X-Foo' => ['Bar', 'Baz']
]
]);
If you want more details information, you can use debug
option like this :
$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'http://www.example.com/user/create', [
'form_params' => [
'email' => '[email protected]',
'name' => 'Test user',
'password' => 'testpassword',
],
// If you want more informations during request
'debug' => true
]);
Documentation is more explicits about new possibilities.
Mozilla has a simple way for drawing SVG on canvas called "Drawing DOM objects into a canvas"
<xs:element name="price" type="decimal">
<xs:attribute name="currency" type="xs:string" value="(euros|pounds|dollars)" />

This would eliminate the need for enumeration completely. You could change type to double if required.
mbstring is a "non-default" extension, that is not enabled by default ; see this page of the manual :
Installation
mbstring is a non-default extension. This means it is not enabled by default. You must explicitly enable the module with the configure option. See the Install section for details
So, you might have to enable that extension, modifying the php.ini file (and restarting Apache, so your modification is taken into account)
I don't use CentOS, but you may have to install the extension first, using something like this (see this page, for instance, which seems to give a solution) :
yum install php-mbstring
(The package name might be a bit different ; so, use yum search to get it :-) )
One of my colleague suggested BFG Repo-Cleaner which I think powerful. It is not only delete unwanted data but also clean your repository from any related commit information.

Looks like your file.next() line in the while loop is throwing the NoSuchElementException since the scanner reached the end of file. Read the next() java API here
Also you should not call next() in the loop and also in the while condition. In the while condition you should check if next token is available and inside the while loop check if its equal to treasure.
git checkout -f
must work, if your previous state is clean.

What you posted has a syntax error, but it makes no difference as you cannot pass HTTP headers via $.post()
.
Provided you're on jQuery version >= 1.5, switch to $.ajax()
and pass the headers
(docs) option. (If you're on an older version of jQuery, I will show you how to do it via the beforeSend
option.)
$.ajax({
url: 'https://url.com',
type: 'post',
data: {
access_token: 'XXXXXXXXXXXXXXXXXXX'
},
headers: {
Header_Name_One: 'Header Value One', //If your header name has spaces or any other char not appropriate
"Header Name Two": 'Header Value Two' //for object property name, use quoted notation shown in second
},
dataType: 'json',
success: function (data) {
console.info(data);
}
});
If you want to replace multiple values in a data frame, looping through all columns might help.
Say you want to replace ""
and 100
:
na_codes <- c(100, "")
for (i in seq_along(df)) {
df[[i]][df[[i]] %in% na_codes] <- NA
}
width: '100%'
and alignSelf: 'stretch'
didn't work for me. Dimensions
didn't suite my task cause I needed to operate on a deeply nested view. Here's what worked for me, if I rewrite your code. I just added some more View
s and used flex
properties to achieve the needed layout:
{/* a column */}
<View style={styles.container}>
{/* some rows here */}
<Text style={styles.welcome}>
Welcome to React Natives
</Text>
{/* this row should take all available width */}
<View style={{ flexDirection: 'row' }}>
{/* flex 1 makes the view take all available width */}
<View style={{ flex: 1 }}>
<Text style={styles.line1}>
line1
</Text>
</View>
{/* I also had a button here, to the right of the text */}
</View>
{/* the rest of the rows */}
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
Yes, you can do

if you want to select column with specific name then just do
A=mtcars[,which(conames(mtcars)==cols[1])]
#and then
colnames(mtcars)[A]=cols[1]
you can run it in loop as well reverse way to add dynamic name eg if A is data frame and xyz is column to be named as x then I do like this
A$tmp=xyz
colnames(A)[colnames(A)=="tmp"]=x
again this can also be added in loop
One of the Related posts gave me the (simple) answer.
Apparently the auto
value on the grid-template-rows
property does exactly what I was looking for.
.grid {
display:grid;
grid-template-columns: 1fr 1.5fr 1fr;
grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
grid-gap:10px;
height: calc(100vh - 10px);
}
I got the same error in this case:
var result = Db.SystemLog
.Where(log =>
eventTypeValues.Contains(log.EventType)
&& (
search.Contains(log.Id.ToString())
|| log.Message.Contains(search)
|| log.PayLoad.Contains(search)
|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
)
)
.OrderByDescending(log => log.Id)
.Select(r => r);
After spending way too much time debugging, I figured out that error appeared in the logic expression.
The first line search.Contains(log.Id.ToString())
does work fine, but the last line that deals with a DateTime object made it fail miserably:
|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
Remove the problematic line and problem solved.
I do not fully understand why, but it seems as ToString() is a LINQ expression for strings, but not for Entities. LINQ for Entities deals with database queries like SQL, and SQL has no notion of ToString(). As such, we can not throw ToString() into a .Where() clause.
But how then does the first line work? Instead of ToString(), SQL have CAST
and CONVERT
, so my best guess so far is that linq for entities uses that in some simple cases. DateTime objects are not always found to be so simple...

By the way. whenever my forms call the formclosed or form closing event I close the applciation with a this.Hide() function. Does that affect how my application is behaving now?
In short, yes. The entire application will end when the main form (the form started via Application.Run
in the Main
method) is closed (not hidden).
If your entire application should always fully terminate whenever your main form is closed then you should just remove that form closed handler. By not canceling that event and just letting them form close when the user closes it you will get your desired behavior. As for all of the other forms, if you don't intend to show that same instance of the form again you just just let them close, rather than preventing closure and hiding them. If you are showing them again, then hiding them may be fine.
If you want to be able to have the user click the "x" for your main form, but have another form stay open and, in effect, become the "new" main form, then it's a bit more complicated. In such a case you will need to just hide your main form rather than closing it, but you'll need to add in some sort of mechanism that will actually close the main form when you really do want your app to end. If this is the situation that you're in then you'll need to add more details to your question describing what types of applications should and should not actually end the program.
This was not working for me in Firefox.
We added a conditional based on whether the code places the overflow at the html level. See Animate scrollTop not working in firefox.
var $header = $("#header #menu-wrap-left"),
$clone = $header.before($header.clone().addClass("clone"));
$(window).on("scroll", function() {
var fromTop = Array();
fromTop["body"] = $("body").scrollTop();
fromTop["html"] = $("body,html").scrollTop();
if (fromTop["body"])
$('body').toggleClass("down", (fromTop["body"] > 650));
if (fromTop["html"])
$('body,html').toggleClass("down", (fromTop["html"] > 650));
});

Functions are easy to call inside a select loop, but they don't let you run inserts, updates, deletes, etc. They are only useful for query operations. You need a stored procedure to manipulate the data.
So, the real answer to this question is that you must iterate through the results of a select statement via a "cursor" and call the procedure from within that loop. Here's an example:
DECLARE @myId int;
DECLARE @myName nvarchar(60);
DECLARE myCursor CURSOR FORWARD_ONLY FOR
SELECT Id, Name FROM SomeTable;
OPEN myCursor;
FETCH NEXT FROM myCursor INTO @myId, @myName;
WHILE @@FETCH_STATUS = 0 BEGIN
EXECUTE dbo.myCustomProcedure @myId, @myName;
FETCH NEXT FROM myCursor INTO @myId, @myName;
END;
CLOSE myCursor;
DEALLOCATE myCursor;
Note that @@FETCH_STATUS
is a standard variable which gets updated for you. The rest of the object names here are custom.
I tried all the methods I can find online and failed. Then I read this post and get some ideas from @Alex answer. Then I search about ""credsStore": "osxkeychain"" which is used in my config.json.

As already answered, you can simply use the trace command:
console.trace("I am here");
However, if you came to this question searching about how to log the stack trace of an exception, you can simply log the Exception object.
try {
// if something unexpected
throw new Error("Something unexpected has occurred.");
} catch (e) {
console.error(e);
}
It will log:
Error: Something unexpected has occurred.
at main (c:\Users\Me\Documents\MyApp\app.js:9:15)
at Object. (c:\Users\Me\Documents\MyApp\app.js:17:1)
at Module._compile (module.js:460:26)
at Object.Module._extensions..js (module.js:478:10)
at Module.load (module.js:355:32)
at Function.Module._load (module.js:310:12)
at Function.Module.runMain (module.js:501:10)
at startup (node.js:129:16)
at node.js:814:3
If your Node.js version is < than 6.0.0, logging the Exception object will not be enough. In this case, it will print only:
[Error: Something unexpected has occurred.]
For Node version < 6, use console.error(e.stack)
instead of console.error(e)
to print the error message plus the full stack, like the current Node version does.
Note: if the exception is created as a string like throw "myException"
, it's not possible to retrieve the stack trace and logging e.stack
yields undefined.
To be safe, you can use
console.error(e.stack || e);
and it will work for old and new Node.js versions.
It would be better if you would describe the reason why you need garbage collection. If you are using SWT, you can dispose resources such as Image
and Font
to free memory. For instance:
Image img = new Image(Display.getDefault(), 16, 16);
img.dispose();
There are also tools to determine undisposed resources.
Does
git add -A && git commit -m "Your Message"
count as a "single command"?
To have it as a git alias
, use:
git config --global alias.coa "!git add -A && git commit -m"
and commit all files, including new files, with a message with:
git coa "A bunch of horrible changes"
From git add
documentation:
-A, --all, --no-ignore-removal
Update the index not only where the working tree has a file matching but also where the index already has an entry. This adds, modifies, and removes index entries to match the working tree.
If no
<pathspec>
is given when -A option is used, all files in the entire working tree are updated (old versions of Git used to limit the update to the current directory and its subdirectories).

I found this code works for me:
public String Translate(String word)
{
var toLanguage = "en";//English
var fromLanguage = "de";//Deutsch
var url = $"https://translate.googleapis.com/translate_a/single?client=gtx&sl={fromLanguage}&tl={toLanguage}&dt=t&q={HttpUtility.UrlEncode(word)}";
var webClient = new WebClient
{
Encoding = System.Text.Encoding.UTF8
};
var result = webClient.DownloadString(url);
try
{
result = result.Substring(4, result.IndexOf("\"", 4, StringComparison.Ordinal) - 4);
return result;
}
catch
{
return "Error";
}
}
The primitive data types prefixed with "u" are unsigned versions with the same bit sizes. Effectively, this means they cannot store negative numbers, but on the other hand they can store positive numbers twice as large as their signed counterparts. The signed counterparts do not have "u" prefixed.
The limits for int (32 bit) are:
int: –2147483648 to 2147483647
uint: 0 to 4294967295
And for long (64 bit):
long: -9223372036854775808 to 9223372036854775807
ulong: 0 to 18446744073709551615
Try running this code in your script.
document.getElementById("dummy").remove();
And it will hopefully remove the element/button.
It's a Bash feature called "tilde expansion". It's a function of the shell, not the OS. You'll get different behavior with csh, for example.
To answer your question about where the information comes from: your home directory comes from the variable $HOME
(no matter what you store there), while other user's homes are retrieved real-time using getpwent()
. This function is usually controlled by NSS; so by default values are pulled out of /etc/passwd
, though it can be configured to retrieve the information using any source desired, such as NIS, LDAP or an SQL database.
Tilde expansion is more than home directory lookup. Here's a summary:
~ $HOME
~fred (freds home dir)
~+ $PWD (your current working directory)
~- $OLDPWD (your previous directory)
~1 `dirs +1`
~2 `dirs +2`
~-1 `dirs -1`
dirs
and ~1
, ~-1
, etc., are used in conjunction with pushd
and popd
.
With recent version of Pandas, you can do

Just like with the solutions above, the axes will be different for each subplot. I have not solved that one yet.
There's no need to start idle transactions on the master. In postgresql-9.1 the most direct way to solve this problem is by setting
hot_standby_feedback = on
This will make the master aware of long-running queries. From the docs:
The first option is to set the parameter hot_standby_feedback, which prevents VACUUM from removing recently-dead rows and so cleanup conflicts do not occur.
Why isn't this the default? This parameter was added after the initial implementation and it's the only way that a standby can affect a master.
The following converts all files in a folder.
Create backup folder of original files.

Convert all files in US ASCII encoding to UTF-8 (single line command)
for f in $(file -i * .sql | grep us-ascii | cut -d ':' -f 1); do iconv -f us-ascii -t utf-8 $f -o $ f.utf-8 && mv $f backup / && mv "$f.utf-8" $f; done
Convert all files in encoding ISO 8859-1 to UTF-8 (single line command)
for f $(file -i * .sql | grep iso-8859-1 | cut -d ':' -f 1); do iconv -f iso-8859-1 -t utf-8 $f -o $f.utf-8 && mv $f backup / && mv "$f.utf-8" $f; done
To add ANDROID_HOME value permanently,
gedit ~/.bashrc
and add the following lines
export ANDROID_HOME=/root/Android/Sdk
PATH=$PATH:$ANDROID_HOME/tools
Save the file and you need not update ANDROID_HOME value everytime.
The accepted solution doesn't cover edge cases. I found the way to do this with 4KB script. Handle your input and convert a data.
Examples:
00:00:00 -> 00:00:00
12:01 -> 12:01:00
12 -> 12:00:00
25 -> 00:00:00
12:60:60 -> 12:00:00
1dg46 -> 14:06
You got the idea... Check it https://github.com/alekspetrov/time-input-js
Another alternative would be JasperReports: JasperReports Library. It uses iText itself and is more than a PDF library you asked for, but if it fits your needs I'd go for it.
Simply put, it allows you to design reports that can be filled during runtime. If you use a custom datasource, you might be able to integrate JasperReports easily into the existing system. It would save you the whole layouting troubles, e.g. when invoices span over more sites where each side should have a footer and so on.
To well understand the behaviour, you can run this code:
#include <iostream>
class MyClass
{
public:
MyClass() { std::cout << "run constructor MyClass::MyClass()" << std::endl; }
~MyClass() { std::cout << "run destructor MyClass::~MyClass()" << std::endl; }
MyClass(const MyClass& x) { std::cout << "run copy constructor MyClass::MyClass(const MyClass&)" << std::endl; }
MyClass& operator = (const MyClass& x) { std::cout << "run assignation MyClass::operator=(const MyClass&)" << std::endl; }
};
MyClass my_function()
{
std::cout << "run my_function()" << std::endl;
MyClass a;
std::cout << "my_function is going to return a..." << std::endl;
return a;
}
int main(int argc, char** argv)
{
MyClass b = my_function();
MyClass c;
c = my_function();
return 0;
}
The output is the following:
run my_function()
run constructor MyClass::MyClass()
my_function is going to return a...
run constructor MyClass::MyClass()
run my_function()
run constructor MyClass::MyClass()
my_function is going to return a...
run assignation MyClass::operator=(const MyClass&)
run destructor MyClass::~MyClass()
run destructor MyClass::~MyClass()
run destructor MyClass::~MyClass()
Note that this example was provided in C++03 context, it could be improved for C++ >= 11
This is an example of a good one and also an example of why you would never want to write one. It is a Fowler / Noll / Vo (FNV) Hash which is equal parts computer science genius and pure voodoo:
unsigned fnv_hash_1a_32 ( void *key, int len ) {
unsigned char *p = key;
unsigned h = 0x811c9dc5;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x01000193;
return h;
}
unsigned long long fnv_hash_1a_64 ( void *key, int len ) {
unsigned char *p = key;
unsigned long long h = 0xcbf29ce484222325ULL;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x100000001b3ULL;
return h;
}
Edit:
It's called the carriage return, or \r
Use
print i/len(some_list)*100," percent complete \r",
The comma prevents print from adding a newline. (and the spaces will keep the line clear from prior output)
Also, don't forget to terminate with a print ""
to get at least a finalizing newline!
Use below code to populate selected option from your model.
<select id="roomForListing" ng-model="selectedRoom.roomName" >

</select>
As far as I know you can't do this with string.Format ... you would have to handle this yourself. You could just strip out all non-numeric characters and then do something like:
string.Format("({0}) {1}-{2}",
phoneNumber.Substring(0, 3),
phoneNumber.Substring(3, 3),
phoneNumber.Substring(6));
This assumes the data has been entered correctly, which you could use regular expressions to validate.
You can use arguments with default values.
def someMethod(def mandatory,def optional=null){}
if argument "optional" not exist, it turns to "null".

To reset the timer, you would need to set and clear out the timer variable
$time_out_handle = 0;
window.clearTimeout($time_out_handle);
$time_out_handle = window.setTimeout( function(){---}, 60000 );
This was the shortest way I could find to sort a DataTable without having to create any new variables.
DataTable.DefaultView.Sort = "ColumnName ASC"
DataTable = DataTable.DefaultView.ToTable
Where:
ASC - Ascending
DESC - Descending
ColumnName - The column you want to sort by
DataTable - The table you want to sort

The default for matrix
is to have 1 column. To explicitly have 0 columns, you need to write
matrix(, nrow = 15, ncol = 0)
A better way would be to preallocate the entire matrix and then fill it in

for(column in 1:n.columns){
mat[, column] <- vector
}
Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC 2010 session #209, which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related.
You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force.
Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups.
I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.
Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly (knowing the password, of course) without the need to even undersand its algorithm. It's not that easy anymore, unfortunately.
I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested.
In theory, Apple's algos should be designed in a way that makes the data still safe (i.e. practically unbreakable by brute force methods) to any attacker knowing the exact encryption method. And in WWDC session 209 they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions. After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help.
Good luck!

If you want to rotate a vector you should construct what is known as a rotation matrix.
Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are
x' = x cos ? - y sin ?
y' = x sin ? + y cos ?
To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider
Unit vector along X axis = <1, 0>
x' = 1 cos 90 - 0 sin 90 = 0
y' = 1 sin 90 + 0 cos 90 = 1
New coordinates of the vector, <x', y'> = <0, 1> ? Y-axis
When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is
|cos ? -sin ?| |x| = |x cos ? - y sin ?| = |x'|
|sin ? cos ?| |y| |x sin ? + y cos ?| |y'|
That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be
|cos ? -sin ? 0| |x| |x cos ? - y sin ?| |x'|
|sin ? cos ? 0| |y| = |x sin ? + y cos ?| = |y'|
| 0 0 1| |z| | z | |z'|
around the Y-axis would be
| cos ? 0 sin ?| |x| | x cos ? + z sin ?| |x'|
| 0 1 0| |y| = | y | = |y'|
|-sin ? 0 cos ?| |z| |-x sin ? + z cos ?| |z'|
around the X-axis would be
|1 0 0| |x| | x | |x'|
|0 cos ? -sin ?| |y| = |y cos ? - z sin ?| = |y'|
|0 sin ? cos ?| |z| |y sin ? + z cos ?| |z'|
Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.
Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.
I hope this clarifies basic rotation.
The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.
I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).
A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.
An alternative is to normalize the data. Below are three sets of data with widely varying ranges. In the top chart you can see the variation in one series clearly, in another not so clearly, and the third not at all.
In the second range, I have adjusted the series names to include the data range, using this formula in cell C15 and copying it to D15:E15
=C2&" ("&MIN(C3:C9)&" to "&MAX(C3:C9)&")"
I have normalized the values in the data range using this formula in C15 and copying it to the entire range C16:E22
=100*(C3-MIN(C$3:C$9))/(MAX(C$3:C$9)-MIN(C$3:C$9))
In the second chart, you can see a pattern: all series have a low in January, rising to a high in March, and dropping to medium-low value in June or July.
You can modify the normalizing formula however you need:
=100*C3/MAX(C$3:C$9)
=C3/MAX(C$3:C$9)
=(C3-AVERAGE(C$3:C$9))/STDEV(C$3:C$9)
etc.
A few key changes to Daniel Galasko's answer fixed all my problems. Unfortunately, I don't have enough reputation to comment directly (yet).
In step 1, when using Auto Layout, simply add a single parent UIView to the cell. EVERYTHING inside the cell must be a subview of the parent. That answered all of my problems. While Xcode adds this for UITableViewCells automatically, it doesn't (but it should) for UICollectionViewCells. According to the docs:
To configure the appearance of your cell, add the views needed to present the data item’s content as subviews to the view in the contentView property. Do not directly add subviews to the cell itself.
Then skip step 3 entirely. It isn't needed.

This is an old, answered, question, but @Alexandre asked "Why would anyone want to do this?", and I thought that I might provide an example usage that I am considering this afternoon.
Legacy code. Uses naked pointers Obj*obj with a delete obj at the end.
Unfortunately I need sometimes, not often, to keep the object alive longer.
I am considering making it a reference counted smart pointer. But there would be lots of code to change, if I was to use ref_cnt_ptr<Obj>
everywhere. And if you mix naked Obj* and ref_cnt_ptr, you can get the object implicitly deleted when the last ref_cnt_ptr goes away, even though there are Obj* still alive.
So I am thinking about creating an explicit_delete_ref_cnt_ptr. I.e. a reference counted pointer where the delete is only done in an explicit delete routine. Using it in the one place where the existing code knows the lifetime of the object, as well as in my new code that keeps the object alive longer.
Incrementing and decrementing the reference count as explicit_delete_ref_cnt_ptr get manipulated.
But NOT freeing when the reference count is seen to be zero in the explicit_delete_ref_cnt_ptr destructor.
Only freeing when the reference count is seen to be zero in an explicit delete-like operation. E.g. in something like:
template<typename T> class explicit_delete_ref_cnt_ptr {
private:
T* ptr;
int rc;
...
public:
void delete_if_rc0() {
if( this->ptr ) {
this->rc--;
if( this->rc == 0 ) {
delete this->ptr;
}
this->ptr = 0;
}
}
};
OK, something like that. It's a bit unusual to have a reference counted pointer type not automatically delete the object pointed to in the rc'ed ptr destructor. But it seems like this might make mixing naked pointers and rc'ed pointers a bit safer.
But so far no need for delete this.
But then it occurred to me: if the object pointed to, the pointee, knows that it is being reference counted, e.g. if the count is inside the object (or in some other table), then the routine delete_if_rc0 could be a method of the pointee object, not the (smart) pointer.
class Pointee {
private:
int rc;
...
public:
void delete_if_rc0() {
this->rc--;
if( this->rc == 0 ) {
delete this;
}
}
}
};
Actually, it doesn't need to be a member method at all, but could be a free function:
map<void*,int> keepalive_map;
template<typename T>
void delete_if_rc0(T*ptr) {
void* tptr = (void*)ptr;
if( keepalive_map[tptr] == 1 ) {
delete ptr;
}
};
(BTW, I know the code is not quite right - it becomes less readable if I add all the details, so I am leaving it like this.)

rectangles.add(new Rectangle(length,width));
//This passes the length and width values to the rectangle constructor,
which will create a new Rectangle and add it to the ArrayList.
}
If you have a new database and you make a fresh clean import, the problem may come from inserting data that contains a '0' incrementation and this would transform to '1' with AUTO_INCREMENT
and cause this error.
My solution was to use in the sql import file.
SET SESSION sql_mode='NO_AUTO_VALUE_ON_ZERO';
note - Lepl is no longer maintained or supported.
RFC 3696 defines "best practices" for URL validation - http://www.faqs.org/rfcs/rfc3696.html
The latest release of Lepl (a Python parser library) includes an implementation of RFC 3696. You would use it something like:
from lepl.apps.rfc3696 import Email, HttpUrl
# compile the validators (do once at start of program)
valid_email = Email()
valid_http_url = HttpUrl()
# use the validators (as often as you like)
if valid_email(some_email):
# email is ok
else:
# email is bad
if valid_http_url(some_url):
# url is ok
else:
# url is bad
Although the validators are defined in Lepl, which is a recursive descent parser, they are largely compiled internally to regular expressions. That combines the best of both worlds - a (relatively) easy to read definition that can be checked against RFC 3696 and an efficient implementation. There's a post on my blog showing how this simplifies the parser - http://www.acooke.org/cute/LEPLOptimi0.html
Lepl is available at http://www.acooke.org/lepl and the RFC 3696 module is documented at http://www.acooke.org/lepl/rfc3696.html
This is completely new in this release, so may contain bugs. Please contact me if you have any problems and I will fix them ASAP. Thanks.

Here is a jQuery handler that can be used to stop enter submits, and also stop backspace key -> back. The (keyCode: selectorString) pairs in the "keyStop" object are used to match nodes that shouldn't fire their default action.
Remember that the web should be an accessible place, and this is breaking keyboard users' expectations. That said, in my case the web application I am working on doesn't like the back button anyway, so disabling its key shortcut is OK. The "should enter -> submit" discussion is important, but not related to the actual question asked.
Here is the code, up to you to think about accessibility and why you would actually want to do this!
$(function(){
var keyStop = {
8: ":not(input:text, textarea, input:file, input:password)", // stop backspace = back
13: "input:text, input:password", // stop enter = submit
end: null
};
$(document).bind("keydown", function(event){
var selector = keyStop[event.which];
if(selector !== undefined && $(event.target).is(selector)) {
event.preventDefault(); //stop event
}
return true;
});
});
to me stopping the application and issuing ng serve fixed the problem
Here's my answer - where the 'pop' is inefficient. Seems that all algorithms that come immediately to mind have N complexity, where N is the size of the list: whether you choose to do work on the 'pop' or do work on the 'push'
The algorithm where lists are traded back and fourth may be better, as a size calculation is not needed, although you still need to loop and compare with empty.
you can prove this algorithm cannot be written faster than N by noting that the information about the last element in a queue is only available through knowing the size of the queue, and that you must destroy data to get to that element, hence the 2nd queue.
The only way to make this faster is to not to use queues in the first place.
from data_structures import queue
class stack(object):
def __init__(self):
q1= queue
q2= queue #only contains one item at most. a temp var. (bad?)
def push(self, item):
q1.enque(item) #just stick it in the first queue.
#Pop is inefficient
def pop(self):
#'spin' the queues until q1 is ready to pop the right value.
for N 0 to self.size-1
q2.enqueue(q1.dequeue)
q1.enqueue(q2.dequeue)
return q1.dequeue()
@property
def size(self):
return q1.size + q2.size
@property
def isempty(self):
if self.size > 0:
return True
else
return False
You'll find the answer to your question in the help page for ?axis
.
Here is one of the help page examples, modified with your data:
Option 1: use xaxp
to define the axis labels
plot(x,y, xaxt="n")
axis(1, xaxp=c(10, 200, 19), las=2)
Option 2: Use at
and seq()
to define the labels:
plot(x,y, xaxt="n")
axis(1, at = seq(10, 200, by = 10), las=2)
Both these options yield the same graphic:
PS. Since you have a large number of labels, you'll have to use additional arguments to get the text to fit in the plot. I use las
to rotate the labels.
Try to add next define at start of your .c file:

move.CompleteMove()
does not return a value (perhaps it just prints something). Any method that does not return a value returns None
, and you have assigned None
to self.values
.
Here is an example of this:
>>> def hello(x):
... print x*2
...
>>> hello('world')
worldworld
>>> y = hello('world')
worldworld
>>> y
>>>
You'll note y
doesn't print anything, because its None
(the only value that doesn't print anything on the interactive prompt).
You have to use a Class
instance because of the generic type erasure during compilation.
public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
try {
return clazz.cast(o);
} catch(ClassCastException e) {
return null;
}
}
The declaration of that method is:
public T cast(Object o)
This can also be used for array types. It would look like this:
final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);
Note that when someObject
is passed to convertToInstanceOfObject
it has the compile time type Object
.

sometimes when data grow bigger mysql WHERE IN's could be pretty slow because of query optimization. Try using STRAIGHT_JOIN to tell mysql to execute query as is, e.g.

its super easy.
You'll need each machine to have it's own copy of ElasticSearch (simply copy the one you have now) -- the reason is that each machine / node whatever is going to keep it's own files that are sharded accross the cluster.
The only thing you really need to do is edit the config file to include the name of the cluster.
If all machines have the same cluster name elasticsearch will do the rest automatically (as long as the machines are all on the same network)
Read here to get you started: https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html
When you create indexes (where the data goes) you define at that time how many replicas you want (they'll be distributed around the cluster)
Use a dot or a pipe as the field separator:
awk -v FS='[.|]' '{
printf "%s%s %s.%s\n", toupper(substr($4,1,1)), substr($4,2), $1, $2
}' << END

The time and space complexities are not related to each other. They are used to describe how much space/time your algorithm takes based on the input.
For example when the algorithm has space complexity of:
O(1)
- constant - the algorithm uses a fixed (small) amount of space which doesn't depend on the input. For every size of the input the algorithm will take the same (constant) amount of space. This is the case in your example as the input is not taken into account and what matters is the time/space of the print
command.O(n)
, O(n^2)
, O(log(n))
... - these indicate that you create additional objects based on the length of your input. For example creating a copy of each object of v
storing it in an array and printing it after that takes O(n)
space as you create n
additional objects.In contrast the time complexity describes how much time your algorithm consumes based on the length of the input. Again:
O(1)
- no matter how big is the input it always takes a constant time - for example only one instruction. Like
function(list l) {
print("i got a list");
}
O(n)
, O(n^2)
, O(log(n))
- again it's based on the length of the input. For example
function(list l) {
for (node in l) {
print(node);
}
}
Note that both last examples take O(1)
space as you don't create anything. Compare them to
function(list l) {
list c;
for (node in l) {
c.add(node);
}
}
which takes O(n)
space because you create a new list whose size depends on the size of the input in linear way.
Your example shows that time and space complexity might be different. It takes v.length * print.time
to print all the elements. But the space is always the same - O(1)
because you don't create additional objects. So, yes, it is possible that an algorithm has different time and space complexity, as they are not dependent on each other.

Just don't set the height property in HighCharts and it will handle it dynamically for you so long as you set a height on the chart's containing element. It can be a fixed number or a even a percent if position is absolute.
By default the height is calculated from the offset height of the containing element
Example: http://jsfiddle.net/wkkAd/149/
#container {
height:100%;
width:100%;
position:absolute;
}
FATAL: could not load server certificate file "/etc/ssl/certs/ssl-cert-snakeoil.pem": No such file or directory

In my opinion, some of the node.js examples are quite contrived.
You might expect to see something more like this in the real world
// square.js
function Square(width) {
if (!(this instanceof Square)) {
return new Square(width);
}
this.width = width;
};
Square.prototype.area = function area() {
return Math.pow(this.width, 2);
};
module.exports = Square;
Usage
var Square = require("./square");
// you can use `new` keyword
var s = new Square(5);
s.area(); // 25
// or you can skip it!
var s2 = Square(10);
s2.area(); // 100
For the ES6 people
class Square {
constructor(width) {
this.width = width;
}
area() {
return Math.pow(this.width, 2);
}
}
export default Square;
Using it in ES6
import Square from "./square";
// ...
When using a class, you must use the new
keyword to instatiate it. Everything else stays the same.
I noticed that you can also get errors if you don't specify the angles correctly, even when using glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z))
you still might run into problems. The fix I found for this was specifying the type as glm::rotate(Model, (glm::mediump_float)90, glm::vec3(x, y, z))
instead of just saying glm::rotate(Model, 90, glm::vec3(x, y, z))
Or just write the second argument, the angle in radians (previously in degrees), as a float with no cast needed such as in:
glm::mat4 rotationMatrix = glm::rotate(glm::mat4(1.0f), 3.14f, glm::vec3(1.0));
You can add glm::radians() if you want to keep using degrees. And add the includes:
#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"
Since inline events are executed as functions you can simply use arguments.
<p id="p" onclick="doSomething.apply(this, arguments)">
and
function doSomething(e) {
if (!e) e = window.event;
// 'e' is the event.
// 'this' is the P element
}
The 'event' that is mentioned in the accepted answer is actually the name of the argument passed to the function. It has nothing to do with the global event.
The following class will make a full-screen modal in Bootstrap:
.full-screen {
width: 100%;
height: 100%;
margin: 0;
top: 0;
left: 0;
}
I'm not sure how the inner content of your modal is structured, this may have an effect on the overall height depending on the CSS that is associated with it.
You don't add links to style sheets. They are for describing the style of the page. You would change your mark-up or add JavaScript to navigate when the image is clicked.
Based only on your style you would have:

I fixed this issue by reinstalling it in Program Files, it originally tried to install it in c:/Users/.../AppData/Android/...
.
Mine was caused by a user permission issue that running as admin didn't seem to fix (perhaps because they call batch files?).
I use Butterknife with switch-case to handle this kind of cases:
@OnClick({R.id.button_bireysel, R.id.button_kurumsal})
public void onViewClicked(View view) {
switch (view.getId()) {
case R.id.button_bireysel:
//Do something
break;
case R.id.button_kurumsal:
//Do something
break;
}
}
But the thing is there is no default case and switch statement falls through
When starting your call, it looks fine.
There is a difference between android 11+ and down in bringing your app to the front though.
Android 10 or less you need to start a new intent, android 11+ you simply use BringTaskToFront
In the call state IDLE:
if (Build.VERSION.SDK_INT >= 11) {
ActivityManager am = (ActivityManager) activity.getSystemService(Activity.ACTIVITY_SERVICE);
am.moveTaskToFront(MyActivity.MyActivityTaskId, ActivityManager.MOVE_TASK_WITH_HOME);
} else {
Intent intent = new Intent(activity, MyActivity.class);
activity.startActivity(intent);
}
I set the MyActivity.MyActivityTaskId
when making the call on my activity like so, it this doesnt work, set this variable on the parent activity page of the page you want to get back to.
MyActivity.MyActivityTaskId = this.getTaskId();
MyActivityTaskId
is a static variable on my activity class
public static int MyActivityTaskId = 0;
I hope this will work for you. I use the above code a bit differently, I open my app as soon as the call is answered sothat the user can see the details of the caller.
I have set some stuff in the AndroidManifest.xml
as well:
/*Dont really know if this makes a difference*/
<activity android:name="MyActivity" android:taskAffinity="" android:launchMode="singleTask" />
and permissions:
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.REORDER_TASKS" />
Please ask questions if or when you get stuck.

As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:
<?php
$world = _("World");
$str = <<<EOF
<p>Hello</p>
<p>$world</p>
EOF;
echo $str;
?>
a workaround idea that comes to mind is building a class with a magic getter method.
You would declare a class like this:
class Translator
{
public function __get($name) {
return _($name); // Does the gettext lookup
}
}
Initialize an object of the class at some point:
$translate = new Translator();
You can then use the following syntax to do a gettext lookup inside a HEREDOC block:
$str = <<<EOF
<p>Hello</p>
<p>{$translate->World}</p>
EOF;
echo $str;
?>
$translate->World
will automatically be translated to the gettext lookup thanks to the magic getter method.
To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!
, you will have to use the following notation:
$translate->{"Hello World!!!!!!"}
This is all untested but should work.
Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.
I use Jenkins and ran into this problem when trying to perform a release (which requires a git commit). To fix the issues, I needed to add a Custom user name/e-mail address (see picture) This ensured that when the code was checked out it used my build user's name/email address when performing the release. Note, this configuration is available from the Jenkins Multibranch Pipeline project configuration.
If you want to update matching rows in t1 with data from t2 then:
update t1
set (c1, c2, c3) =
(select c1, c2, c3 from t2
where t2.user_id = t1.user_id)
where exists
(select * from t2
where t2.user_id = t1.user_id)
The "where exists" part it to prevent updating the t1 columns to null where no match exists.

People are saying that the symbol doesn't mean addition. This is true, but doesn't explain why a plus-like symbol is used for something that isn't addition.
The answer is that for modulo addition of 1-bit values, 0+0 == 1+1 == 0, and 0+1 == 1+0 == 1. Those are the same values as XOR.
So, plus in a circle in this context means "bitwise addition modulo-2". Which is, as everyone says, XOR for integers. It's common in mathematics to use plus in a circle for an operation which is a sort of addition, but isn't regular integer addition.

The given answer is far from complete. In fact, it is so far from complete that it tends to lead the reader to believe that this answer is OS dependent when it isn't. It also isn't something which is programming language dependent (as some commentators have suggested). I'm going to add more information in order to make this more clear. First, lets give the list of current new line variations (as in, what they've been since 1999):
\r\n
is only used on Windows Notepad, the DOS command line, most of the Windows API and in some (older) Windows apps.\n
is used for all other systems, applications and the Internet.You'll notice that I've put most Windows apps in the \n
group which may be slightly controversial but before you disagree with this statement, please grab a UNIX formatted text file and try it in 10 web friendly Windows applications of your choice (which aren't listed in my exceptions above). What percentage of them handled it just fine? You'll find that they (practically) all implement auto detection of line endings or just use \n
because, while Windows may use \r\n
, the Internet uses \n
. Therefore, it is best practice for applications to use \n
alone if you want your output to be Internet friendly.
PHP also defines a newline character called PHP_EOL
. This constant is set to the OS specific newline string for the machine PHP is running on (\r\n
for Windows and \n
for everything else). This constant is not very useful for webpages and should be avoided for HTML output or for writing most text to files. It becomes VERY useful when we move to command line output from PHP applications because it will allow your application to output to a terminal Window in a consistent manner across all supported OSes.
If you want your PHP applications to work from any server they are placed on, the two biggest things to remember are that you should always just use \n
unless it is terminal output (in which case you use PHP_EOL) and you should also ALWAYS use /
for your path separator (not \
).
The even longer explanation:
An application may choose to use whatever line endings it likes regardless of the default OS line ending style. If I want my text editor to print a newline every time it encounters a period that is no harder than using the \n
to represent a newline because I'm interpreting the text as I display it anyway. IOW, I'm fiddling around with measuring the width of each character so it knows where to display the next so it is very simple to add a statement saying that if the current char is a period then perform a newline action (or if it is a \n
then display a period).
Aside from the null terminator, no character code is sacred and when you write a text editor or viewer you are in charge of translating the bits in your file into glyphs (or carriage returns) on the screen. The only thing that distinguishes a control character such as the newline from other characters is that most font sets don't include them (meaning they don't have a visual representation available).
That being said, if you are working at a higher level of abstraction then you probably aren't making your own textbox controls. If this is the case then you're stuck with whatever line ending that control makes available to you. Even in this case it is a simple matter to automatically detect the line ending style of any string and make the conversion before you load your text into the control and then undo it when you read from that control. Meaning, that if you're a desktop application dev and your application doesn't recognize \n
as a newline then it isn't a very friendly application and you really have no excuse because it isn't hard to make it the right way. It also means that whomever wrote Notepad should be ashamed of himself because it really is very easy to do much better and so many people suffer through using it every day.
If you want to change Status Bar Style from the launch screen, You should take this way.
Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:
CSS
#container {
display: table;
width: 300px; /* not required, just for example */
height: 400px; /* not required, just for example */
}
#update {
display: table-cell;
vertical-align: middle;
text-align: center;
}
HTML
<div id="container">
<a id="update" href="#">
<i class="icon-refresh"></i>
</a>
</div>
Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell
display property works.
Take a look at Traverse. It will recursively walk an object tree for you and at every node you have a number of different objects you can access - key of current node, value of current node, parent of current node, full key path of current node, etc. https://github.com/substack/js-traverse. I've used it to good effect on objects that I wanted to scrub circular references to and when I need to do a deep clone while transforming various data bits. Here's some code pulled form their samples to give you a flavor of what it can do.
var id = 54;
var callbacks = {};
var obj = { moo : function () {}, foo : [2,3,4, function () {}] };
var scrubbed = traverse(obj).map(function (x) {
if (typeof x === 'function') {
callbacks[id] = { id : id, f : x, path : this.path };
this.update('[Function]');
id++;
}
});
console.dir(scrubbed);
console.dir(callbacks);
This is roughly how I'd do it: the line is created by setting a border-bottom
on the containing h2
then giving the h2
a smaller line-height
. The text is then put in a nested span
with a non-transparent background.
h2 {_x000D_
width: 100%; _x000D_
text-align: center; _x000D_
border-bottom: 1px solid #000; _x000D_
line-height: 0.1em;_x000D_
margin: 10px 0 20px; _x000D_
} _x000D_
_x000D_
h2 span { _x000D_
background:#fff; _x000D_
padding:0 10px; _x000D_
}
_x000D_
<h2><span>THIS IS A TEST</span></h2>_x000D_
<p>this is some content other</p>

"foreach" is not the name for bash. It is simply "for". You can do things in one line only like:
for fn in `cat filenames.txt`; do cat "$fn"; done

Python eggs are a way of bundling additional information with a Python project, that allows the project's dependencies to be checked and satisfied at runtime, as well as allowing projects to provide plugins for other projects. There are several binary formats that embody eggs, but the most common is '.egg' zipfile format, because it's a convenient one for distributing projects. All of the formats support including package-specific data, project-wide metadata, C extensions, and Python code.
The easiest way to install and use Python eggs is to use the "Easy Install" Python package manager, which will find, download, build, and install eggs for you; all you do is tell it the name (and optionally, version) of the Python project(s) you want to use.
Python eggs can be used with Python 2.3 and up, and can be built using the setuptools package (see the Python Subversion sandbox for source code, or the EasyInstall page for current installation instructions).
The primary benefits of Python Eggs are:
They enable tools like the "Easy Install" Python package manager
.egg files are a "zero installation" format for a Python package; no build or install step is required, just put them on PYTHONPATH or sys.path and use them (may require the runtime installed if C extensions or data files are used)
They can include package metadata, such as the other eggs they depend on
They allow "namespace packages" (packages that just contain other packages) to be split into separate distributions (e.g. zope., twisted., peak.* packages can be distributed as separate eggs, unlike normal packages which must always be placed under the same parent directory. This allows what are now huge monolithic packages to be distributed as separate components.)
They allow applications or libraries to specify the needed version of a library, so that you can e.g. require("Twisted-Internet>=2.0") before doing an import twisted.internet.
They're a great format for distributing extensions or plugins to extensible applications and frameworks (such as Trac, which uses eggs for plugins as of 0.9b1), because the egg runtime provides simple APIs to locate eggs and find their advertised entry points (similar to Eclipse's "extension point" concept).
There are also other benefits that may come from having a standardized format, similar to the benefits of Java's "jar" format.
With introduction of Java 1.8, streams are very useful in solving this kind of problems:
Comparator <DateTime> myComparator = (arg1, arg2)
-> {
if(arg1.lt(arg2))
return -1;
else if (arg1.lteq(arg2))
return 0;
else
return 1;
};
ArrayList<DateTime> sortedList = myList
.stream()
.sorted(myComparator)
.collect(Collectors.toCollection(ArrayList::new));
For Angular 4
Url:
http://example.com/company/100
Router Path :
const routes: Routes = [
{ path: 'company/:companyId', component: CompanyDetailsComponent},
]
Component:
@Component({
selector: 'company-details',
templateUrl: './company.details.component.html',
styleUrls: ['./company.component.css']
})
export class CompanyDetailsComponent{
companyId: string;
constructor(private router: Router, private route: ActivatedRoute) {
this.route.params.subscribe(params => {
this.companyId = params.companyId;
console.log('companyId :'+this.companyId);
});
}
}
Console Output:
companyId : 100
Actually what you are searching is: Optional.map. Your code would then look like:
object.map(o -> "result" /* or your function */)
.orElseThrow(MyCustomException::new);
I would rather omit passing the Optional
if you can. In the end you gain nothing using an Optional
here. A slightly other variant:
public String getString(Object yourObject) {
if (Objects.isNull(yourObject)) { // or use requireNonNull instead if NullPointerException suffices
throw new MyCustomException();
}
String result = ...
// your string mapping function
return result;
}
If you already have the Optional
-object due to another call, I would still recommend you to use the map
-method, instead of isPresent
, etc. for the single reason, that I find it more readable (clearly a subjective decision ;-)).

NSLog(@"%@", decodedString); // foo

I had the same problem with bootstrap datetimepicker extension. Including moment.js before datetimepicker.js was the solution.
The issue that lead me here turned out to be a basic user error - I wasn't including the @
sign in the path of the file and so curl was posting the path/name of the file rather than the contents. The Content-Length
value was therefore 8 rather than the 479 I expected to see given the legnth of my test file.
The Content-Length
header will be automatically calculated when curl reads and posts the file.
curl -i -H "Content-Type: application/xml" --data "@test.xml" -v -X POST https://<url>/<uri/
... < Content-Length: 479 ...
Posting this here to assist other newbies in future.
To get last inserted id in codeigniter
After executing insert query just use one function called insert_id()
on database, it will return last inserted id
Ex:
$this->db->insert('mytable',$data);
echo $this->db->insert_id(); //returns last inserted id
in one line
echo $this->db->insert('mytable',$data)->insert_id();
You use the datetime.datetime.date()
method:
datetime.datetime.now().date()
Obviously, the expression above can (and should IMHO :) be written as:
datetime.date.today()
in may case setting SMTPAuth to true fixed it. Of-course you need to set permissions for "Less secure apps" to Enabled.
$mail->SMTPAuth = true;
Look into twitter cards.
The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook
sharing.
Example:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="http://placekitten.com/250/250">
<meta name="twitter:domain" content="YourDomain.com">
I can show you with an example:
function fullName(first, last) {_x000D_
let fullName = first + " " + last;_x000D_
return fullName;_x000D_
}_x000D_
_x000D_
function fullNameStringInterpolation(first, last) {_x000D_
let fullName = `${first} ${last}`;_x000D_
return fullName;_x000D_
}_x000D_
_x000D_
console.log('Old School: ' + fullName('Carlos', 'Gutierrez'));_x000D_
_x000D_
console.log('New School: ' + fullNameStringInterpolation('Carlos', 'Gutierrez'));
_x000D_
Take a look at algorithms
package, especially the algorithm
environment.
Use this code to ensure the user doesn't just enter spaces but a valid name:
pattern="[a-zA-Z][a-zA-Z0-9\s]*"
When you encounter exceptions like this, the most useful information is generally at the bottom of the stacktrace:
Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
...
at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:246)
The problem is that Tomcat can't find com.mysql.jdbc.Driver
. This is usually caused by the JAR containing the MySQL driver not being where Tomcat expects to find it (namely in the webapps/<yourwebapp>/WEB-INF/lib
directory).

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).
WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.
For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:
ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.
Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.
In the scenarios listed below you should go for WCF:
WEB API is a framework for developing RESTful/HTTP services.
There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.
HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.
s = 'sdsd'
print (s.upper())
upper = raw_input('type in something lowercase.')
lower = raw_input('type in the same thing caps lock.')
print upper.upper()
print lower.lower()
I was able to take from user atilkan's approach and modify it a bit:
For Typescript users;
require.context('@/folder/with/modules', false, /\.ts$/).keys().forEach((fileName => {
import('@/folder/with/modules' + fileName).then((mod) => {
(window as any)[fileName] = mod[fileName];
const module = new (window as any)[fileName]();
// use module
});
}));
A simple readable version is
def find(lst, key, value):
for i, dic in enumerate(lst):
if dic[key] == value:
return i
return -1
This question is not exactly young, but there have come up some alternatives:
Use TRY_CONVERT which is an SQL alternative to TryParse in .NET. IsNumeric() isn’t aware that empty strings are counted as (integer)zero, and that some perfectly valid money symbols, by themselves, are not converted to (money)zero. reference
SELECT @MY_VAR = CASE WHEN TRY_CONVERT(INT,MY_FIELD) IS NOT NULL THEN MY_FIELD
ELSE 0
END
FROM MY_TABLE
WHERE MY_OTHER_FIELD = 'MY_FILTER'
It is no use putting the .fn, it will reffers to the prototype.
What you need to do is $.fancybox.close();
The thing is that you are maybe experiencing another error from js.
There are any errors on screen?
Is your fancybox and jquery the latest releases?
jquery is currently in 1.4.1 and fb in 1.3 something
Experiment putting a link inside the fancybox and put that function in it.
You probably had read that, but in any case, http://fancybox.net/api
One thing that you probably might need to do is isolate each part in order to realize what it is.
Use static_cast<int>
:
int num = static_cast<int>(letter); // if letter='a', num=97
Edit: You probably should try to avoid to use (int)
int num = (int) letter;
check out Why use static_cast<int>(x) instead of (int)x? for more info.
simply multiplying by -1 works in both ways ...
>>> -10 * -1
10
>>> 10 * -1

you can use PHP's end()
$array = array('a' => 1,'b' => 2,'c' => 3);
$lastElement = end($array);
foreach($array as $k => $v) {
echo $v . '<br/>';
if($v == $lastElement) {
// 'you can do something here as this condition states it just entered last element of an array';
}
}
Update1
as pointed out by @Mijoja the above could will have problem if you have same value multiple times in array. below is the fix for it.
$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
//point to end of the array
end($array);
//fetch key of the last element of the array.
$lastElementKey = key($array);
//iterate the array
foreach($array as $k => $v) {
if($k == $lastElementKey) {
//during array iteration this condition states the last element.
}
}
Update2
I found solution by @onteria_ to be better then what i have answered since it does not modify arrays internal pointer, i am updating the answer to match his answer.
$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
// Get array keys
$arrayKeys = array_keys($array);
// Fetch last array key
$lastArrayKey = array_pop($arrayKeys);
//iterate array
foreach($array as $k => $v) {
if($k == $lastArrayKey) {
//during array iteration this condition states the last element.
}
}
Thank you @onteria_
Update3
As pointed by @CGundlach PHP 7.3 introduced array_key_last
which seems much better option if you are using PHP >= 7.3
$array = array('a' => 1,'b' => 2,'c' => 3);
$lastKey = array_key_last($array);
foreach($array as $k => $v) {
echo $v . '<br/>';
if($k == $lastKey) {
// 'you can do something here as this condition states it just entered last element of an array';
}
}
Everytime I install node.js it needs a reboot and then the path is recognized.
As Ponies says in a comment, you cannot mix OLAP functions with aggregate functions.
Perhaps it's easier to get the last completion date for each employee, and join that to a dataset containing the last completion date for each of the three targeted courses.
This is an untested idea that should hopefully put you down the right path:
SELECT employee_number,
course_code,
MAX(course_completion_date) AS max_date,
lcc.LAST_COURSE_COMPLETED
FROM employee_course_completion ecc
LEFT JOIN (
SELECT employee_number,
MAX(course_completion_date) AS LAST_COURSE_COMPLETED
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
) lcc
ON lcc.employee_number = ecc.employee_number
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code, lcc.LAST_COURSE_COMPLETED
The character 0x0C is be invalid in XML 1.0 but would be a valid character in XML 1.1. So unless the xml file specifies the version as 1.1 in the prolog it is simply invalid and you should complain to the producer of this file.
The escape code "
can also be used instead of "
.
var list = arr.Select(i => Int32.Parse(i));
Simple nltk.download() will not solve this issue. I tried the below and it worked for me:
in the nltk folder create a tokenizers folder and copy your punkt folder into tokenizers folder.
This will work.! the folder structure needs to be as shown in the picture
SharePoint lists V: Techniques for managing large lists :
Tutorial By Microsoft
Level: Advanced
Length: 40 - 50 minutes
When a SharePoint list gets large, you might see warnings such as, “This list exceeds the list view threshold,” or “Displaying the newest results below.” Find out why these warnings occur, and learn ways to configure your large list so that it still provides useful information.
After completing this course you will be able to:
try this:
struct Pos{
int x;
int y;
inline Pos& operator=(const Pos& other){
x=other.x;
y=other.y;
return *this;
}
inline Pos operator+(const Pos& other) const {
Pos res {x+other.x,y+other.y};
return res;
}
const inline bool operator==(const Pos& other) const {
return (x==other.x and y == other.y);
}
};
The onunload event is not called in all browsers. Worse, you cannot check the return value of onbeforeunload event. That prevents us from actually preforming a logout function.
However, you can hack around this.
Call logout first thing in the onbeforeunload event. then prompt the user. If the user cancels their logout, automatically login them back in, by using the onfocus event. Kinda backwards, but I think it should work.
'use strict';
var reconnect = false;
window.onfocus = function () {
if (reconnect) {
reconnect = false;
alert("Perform an auto-login here!");
}
};
window.onbeforeunload = function () {
//logout();
var msg = "Are you sure you want to leave?";
reconnect = true;
return msg;
};
The difference is that the post-increment operator i++
returns i
as it was before incrementing, and the pre-increment operator ++i
returns i
as it is after incrementing. If you're asking about a typical for
loop:
for (i = 0; i < 10; i++)
or
for (i = 0; i < 10; ++i)
They're exactly the same, since you're not using i++
or ++i
as a part of a larger expression.
I'm somewhat surprised that no one has mentioned that the original poster might have liked rational numbers to result. Should you be interested in this, the Python-based program Sage has your back. (Currently still based on Python 2.x, though 3.x is under way.)
sage: (20-10) / (100-10)
1/9
This isn't a solution for everyone, because it does do some preparsing so these numbers aren't int
s, but Sage Integer
class elements. Still, worth mentioning as a part of the Python ecosystem.
You could use check constraint with a user defined function to make the check. It is more reliable than a trigger. It can be disabled and reenabled when necessary same as foreign keys and rechecked after a database2 restore.
CREATE FUNCTION dbo.fn_db2_schema2_tb_A
(@column1 INT)
RETURNS BIT
AS
BEGIN
DECLARE @exists bit = 0
IF EXISTS (
SELECT TOP 1 1 FROM DB2.SCHEMA2.tb_A
WHERE COLUMN_KEY_1 = @COLUMN1
) BEGIN
SET @exists = 1
END;
RETURN @exists
END
GO
ALTER TABLE db1.schema1.tb_S
ADD CONSTRAINT CHK_S_key_col1_in_db2_schema2_tb_A
CHECK(dbo.fn_db2_schema2_tb_A(key_col1) = 1)
You can initialize the array by specifying the dimensions. For example
Dim myArray(10) As Integer
Dim myArray(1 to 10) As Integer
If you are working with arrays and if this is your first time then I would recommend visiting Chip Pearson's WEBSITE.
What does this initialize to? For example, what if I want to initialize the entire array to 13?
When you want to initailize the array of 13 elements then you can do it in two ways
Dim myArray(12) As Integer
Dim myArray(1 to 13) As Integer
In the first the lower bound of the array would start with 0
so you can store 13 elements in array. For example
myArray(0) = 1
myArray(1) = 2
'
'
'
myArray(12) = 13
In the second example you have specified the lower bounds as 1
so your array starts with 1
and can again store 13 values
myArray(1) = 1
myArray(2) = 2
'
'
'
myArray(13) = 13
Wnen you initialize an array using any of the above methods, the value of each element in the array is equal to 0
. To check that try this code.
Sub Sample()
Dim myArray(12) As Integer
Dim i As Integer
For i = LBound(myArray) To UBound(myArray)
Debug.Print myArray(i)
Next i
End Sub
or
Sub Sample()
Dim myArray(1 to 13) As Integer
Dim i As Integer
For i = LBound(myArray) To UBound(myArray)
Debug.Print myArray(i)
Next i
End Sub

So, in this example every value would be 13. So if I had an array Dim myArray(300) As Integer, all 300 elements would hold the value 13
Like I mentioned, AFAIK, there is no direct way of achieving what you want. Having said that here is one way which uses worksheet function Rept
to create a repetitive string of 13's. Once we have that string, we can use SPLIT
using ","
as a delimiter. But note this creates a variant array but can be used in calculations.
Note also, that in the following examples myArray
will actually hold 301 values of which the last one is empty - you would have to account for that by additionally initializing this value or removing the last "," from sNum
before the Split
operation.
Sub Sample()
Dim sNum As String
Dim i As Integer
Dim myArray
'~~> Create a string with 13 three hundred times separated by comma
'~~> 13,13,13,13...13,13 (300 times)
sNum = WorksheetFunction.Rept("13,", 300)
sNum = Left(sNum, Len(sNum) - 1)
myArray = Split(sNum, ",")
For i = LBound(myArray) To UBound(myArray)
Debug.Print myArray(i)
Next i
End Sub
Using the variant array in calculations
Sub Sample()
Dim sNum As String
Dim i As Integer
Dim myArray
'~~> Create a string with 13 three hundred times separated by comma
sNum = WorksheetFunction.Rept("13,", 300)
sNum = Left(sNum, Len(sNum) - 1)
myArray = Split(sNum, ",")
For i = LBound(myArray) To UBound(myArray)
Debug.Print Val(myArray(i)) + Val(myArray(i))
Next i
End Sub
Try something like this:
<div id="LoadingImage" style="display: none">
<img src="" />
</div>
<script>
function ajaxCall(){
$("#LoadingImage").show();
$.ajax({
type: "GET",
url: surl,
dataType: "jsonp",
cache : false,
jsonp : "onJSONPLoad",
jsonpCallback: "newarticlescallback",
crossDomain: "true",
success: function(response) {
$("#LoadingImage").hide();
alert("Success");
},
error: function (xhr, status) {
$("#LoadingImage").hide();
alert('Unknown error ' + status);
}
});
}
</script>
For the odd positions, you probably want:
>>>> list_ = list(range(10))
>>>> print list_[1::2]
[1, 3, 5, 7, 9]
>>>>
I face the same issue. I am using docker version:17.09.0-ce
.
I follow below steps:
$ sudo docker build -t ubuntu-test:latest .
It resolved issue and image created successsfully.
Note: build command depend on docker version as well as which build option we are using. :)

Dump in Excel to run:D
You can do this with the "rebase" command. Let's call the branches "main" and "feature":
git checkout feature
git rebase main
The rebase command will replay all of the commits on "feature" as one commit with a parent equal to "main".
You might want to run git merge main
before git rebase main
if "main" has changed since "feature" was created (or since the most recent merge). That way, you still have your full history in case you had a merge conflict.
After the rebase, you can merge your branch to main, which should result in a fast-forward merge:
git checkout main
git merge feature
See the rebase page of Understanding Git Conceptually for a good overview
If you know what column the text/pattern you're looking for (e.g. "yyy") is in, you can just check that specific column to see if it matches, and print it.
For example, given a file with the following contents, (called asdf.txt)
xxx yyy zzz
to only print the second column if it matches the pattern "yyy", you could do something like this:
awk '$2 ~ /yyy/ {print $2}' asdf.txt
Note that this will also match basically any line where the second column has a "yyy" in it, like these:
xxx yyyz zzz
xxx zyyyz
You can just do a cast
int val1 = 1;
float val2 = (float)val1;
or
decimal val3 = 3;
float val4 = (float)val3;
Location is a struct. If there aren't any convenience members, you'll need to reassign the entire Location:
this.balancePanel.Location = new Point(
this.optionsPanel.Location.X,
this.balancePanel.Location.Y);
Most structs are also immutable, but in the rare (and confusing) case that it is mutable, you can also copy-out, edit, copy-in;
var loc = this.balancePanel.Location;
loc.X = this.optionsPanel.Location.X;
this.balancePanel.Location = loc;
Although I don't recommend the above, since structs should ideally be immutable.
Line magics are only supported by the IPython command line. They cannot simply be used inside a script, because %something
is not correct Python syntax.
If you want to do this from a script you have to get access to the IPython API and then call the run_line_magic
function.
Instead of %matplotlib inline
, you will have to do something like this in your script:
from IPython import get_ipython
get_ipython().run_line_magic('matplotlib', 'inline')
A similar approach is described in this answer, but it uses the deprecated magic
function.
Note that the script still needs to run in IPython. Under vanilla Python the get_ipython
function returns None
and get_ipython().run_line_magic
will raise an AttributeError
.
The trick is to add both max-height: 100%;
and max-width: 100%;
to .container img
. Example CSS:
.container {
width: 300px;
border: dashed blue 1px;
}
.container img {
max-height: 100%;
max-width: 100%;
}
In this way, you can vary the specified width of .container
in whatever way you want (200px or 10% for example), and the image will be no larger than its natural dimensions. (You could specify pixels instead of 100% if you didn't want to rely on the natural size of the image.)
