This bug is really annoying..
The only thing that did the trick for me is deleting the project from the workspace, then deleting the .project and .classpath files and then re import it back to the workspace.
Hope it will help others.
Add this dependency in build.gradle
compile 'com.google.android.gms:play-services:6.5.87

Now this works

Take some base date which is the 31st of some month e.g. '20011231'. Then use the
following procedure (I have given 3 identical examples below, only the @dt value differs).
declare @dt datetime;
set @dt = '20140312'
SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');
set @dt = '20140208'
SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');
set @dt = '20140405'
SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');

In order to add support for old browser I highly recommend using strong and community supported solution from:
https://github.com/paulmillr/es6-shim
which is pure ES6 JS polyfills library.
Note that this lib require es5-shim, just follow README.md.
This suffices :
parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling || null);
since if the refnode
(second parameter) is null, a regular appendChild is performed. see here : http://reference.sitepoint.com/javascript/Node/insertBefore
Actually I doubt that the || null
is required, try it and see.
As I understand it, an np-hard problem is not "harder" than an np-complete problem. In fact, by definition, every np-complete problem is:

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:
@keyframes changewidth {
from {
transform: scaleX(1);
}
to {
transform: scaleX(2);
}
}
div {
animation-duration: 0.1s;
animation-name: changewidth;
animation-iteration-count: infinite;
animation-direction: alternate;
}
More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108
Use the backslash to escape a character. For example:
/\\d/
This will match \d instead of a numeric character
Separate these functions from controllers and put them into model file. Then include the model file in your controller.
Try this:
function generateInputs(form, input) {
x = input.value;
for (y = 0; x > y; y++) {
var element = document.createElement('input');
element.type = "text";
element.placeholder = "New Input";
form.appendChild(element);
}
}
_x000D_
input {
padding: 10px;
margin: 10px;
}
_x000D_
<div id="input-form">
<input type="number" placeholder="Desired number of inputs..." onchange="generateInputs(document.getElementById('input-form'), this)" required><br>
</div>
_x000D_
The code above, has a form with an input which accepts a number in it:
<form id="input-form">
<input type="number" placeholder="Desired number of inputs..." onchange="generateInputs(document.getElementById('input-form'), this)"><br>
</form>
The input runs a function onchange
, meaning that when the user has entered a number and clicked submit, it run a function. The user is required to fill out the input with a value before submitting. This value must be numerical. Once submitted the parent form and the input are passed to the function:
...
generateInputs(document.getElementById('input-form'), this)
...
The generate then loops according to the given value inside the input:
...
x = input.value;
for (y=0; x>y; y++) {
...
Then it generates an input inside the form, on each loop:
...
var element = document.createElement('input');
element.type = "text";
element.placeholder = "New Input";
form.appendChild(element);
...
I have also added in a few CSS
stylings to make the inputs
look nice, and some placeholders
as well.

All of this didn't solve it for me on my brand new Ubuntu 15.04.
I removed the LOCAL
and got this command:
LOAD DATA
INFILE A.txt
INTO DB
LINES TERMINATED BY '|';
but then I got:
MySQL said: File 'A.txt' not found (Errcode: 13 - Permission denied)
That led me to this answer from Nelson to another question on stackoverflow which solved the issue for me!
key($arr);
will return the key value for the current array element
You can use lineSpacingExtra
and lineSpacingMultiplier
in your XML file.
You can use strcpy
but remember to end the array with '\0'
char array[20]; char string[100];
array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9'; array[5]='\0';
strcpy(string, array);
printf("%s\n", string);
Here's the solution that worked for me:
var date1 = new Date("08/05/2015 23:41:20");
var date2 = new Date("08/06/2015 02:56:32");
var diff = date2.getTime() - date1.getTime();
var msec = diff;
var hh = Math.floor(msec / 1000 / 60 / 60);
msec -= hh * 1000 * 60 * 60;
var mm = Math.floor(msec / 1000 / 60);
msec -= mm * 1000 * 60;
var ss = Math.floor(msec / 1000);
msec -= ss * 1000;
alert(hh + ":" + mm + ":" + ss);
Should be:
SELECT registrationDate,
(SELECT CASE
WHEN COUNT(*)< 2 THEN 'Ama'
WHEN COUNT(*)< 5 THEN 'SemiAma'
WHEN COUNT(*)< 7 THEN 'Good'
WHEN COUNT(*)< 9 THEN 'Better'
WHEN COUNT(*)< 12 THEN 'Best'
ELSE 'Outstanding'
END as a FROM Articles
WHERE Articles.userId = Users.userId) as ranking,
(SELECT COUNT(*)
FROM Articles
WHERE userId = Users.userId) as articleNumber,
hobbies, etc...
FROM USERS
One thing you could do is sort the numbers using quick sort for instance. Then use a for loop to iterate through the sorted array from 1 to 100. In each iteration, you compare the number in the array with your for loop increment, if you find that the index increment is not the same as the array value, you have found your missing number as well as the missing index.
Sharing a few functions which I created for dates:
Please note that I wanted to get time for a particular location (not just UTC time). If you want UTC time, just remove loc variable and .In(loc) function call.
func GetTimeStamp() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
t := time.Now().In(loc)
return t.Format("20060102150405")
}
func GetTodaysDate() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
current_time := time.Now().In(loc)
return current_time.Format("2006-01-02")
}
func GetTodaysDateTime() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
current_time := time.Now().In(loc)
return current_time.Format("2006-01-02 15:04:05")
}
func GetTodaysDateTimeFormatted() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
current_time := time.Now().In(loc)
return current_time.Format("Jan 2, 2006 at 3:04 PM")
}
func GetTimeStampFromDate(dtformat string) string {
form := "Jan 2, 2006 at 3:04 PM"
t2, _ := time.Parse(form, dtformat)
return t2.Format("20060102150405")
}
Some conventions list all the public methods first, and then all the private ones - that means it's easy to separate the API from the implementation, even when there's no interface involved, if you see what I mean.
Another idea is to group related methods together - this makes it easier to spot seams where you could split your existing large class into several smaller, more targeted ones.
cout << "Enter amount of spaces you would like (integer)" << endl;
cin >> n;
//print n spaces
for (int i = 0; i < n; ++i)
{
cout << " " ;
}
cout <<endl;
js:
var array = fs.readFileSync('file.txt', 'utf8').split('\n');
ts:
var array = fs.readFileSync('file.txt', 'utf8').toString().split('\n');
Following command
docker-compose restart worker
will just STOP and START the container. i.e without loading any changes from the docker-compose.xml
STOP is similar to hibernating in PC . Hence stop/start will not look for any changes made in configuration file . To reload from the recipe of container (docker-compose.xml) we need to remove and create the container (Similar analogy to rebooting the PC )
So commands will be as following
docker-compose stop worker // go to hibernate
docker-compose rm worker // shutdown the PC
docker-compose create worker // create the container from image and put it in hibernate
docker-compose start worker //bring container to life from hibernation
This is what I would do if passed a string buffer to fill and I knew the buffer was big enough (ie at least 16 characters long):
sprintf(buffer, "%d.%d.%d.%d",
(ip >> 24) & 0xFF,
(ip >> 16) & 0xFF,
(ip >> 8) & 0xFF,
(ip ) & 0xFF);
This would be slightly faster than creating a byte array first, and I think it is more readable. I would normally use snprintf, but IP addresses can't be more than 16 characters long including the terminating null.
Alternatively if I was asked for a function returning a char*:
char* IPAddressToString(int ip)
{
char[] result = new char[16];
sprintf(result, "%d.%d.%d.%d",
(ip >> 24) & 0xFF,
(ip >> 16) & 0xFF,
(ip >> 8) & 0xFF,
(ip ) & 0xFF);
return result;
}
Python has nothing built-in to support this. Do you really need to optimize it so much as I don't think that appending will add that much overhead.
However, you can do something like l = [None] * 1000
.
Alternatively, you could use a generator.
This expression will search for non-ASCII values:
[^\x00-\x7F]+
Tick off 'Search Mode = Regular expression', and click Find Next.

This solution appears better to me, regarding maintainability and design for change:
Create the logging property file embedding it in the resource project folder, to be included in the jar file:
# Logging
handlers = java.util.logging.ConsoleHandler
.level = ALL
# Console Logging
java.util.logging.ConsoleHandler.level = ALL
Load the property file from code:
public static java.net.URL retrieveURLOfJarResource(String resourceName) {
return Thread.currentThread().getContextClassLoader().getResource(resourceName);
}
public synchronized void initializeLogger() {
try (InputStream is = retrieveURLOfJarResource("logging.properties").openStream()) {
LogManager.getLogManager().readConfiguration(is);
} catch (IOException e) {
// ...
}
}
Note It takes as an input a US mobile number in any format and optionally accepts a second parameter - set true if you want the output mobile number formatted to look pretty. If the number provided is not a mobile number, it simple returns false. If a mobile number IS detected, it returns the entire sanitized number instead of true.
function isValidMobile(num,format) {
if (!format) format=false
var m1 = /^(\W|^)[(]{0,1}\d{3}[)]{0,1}[.]{0,1}[\s-]{0,1}\d{3}[\s-]{0,1}[\s.]{0,1}\d{4}(\W|$)/
if(!m1.test(num)) {
return false
}
num = num.replace(/ /g,'').replace(/\./g,'').replace(/-/g,'').replace(/\(/g,'').replace(/\)/g,'').replace(/\[/g,'').replace(/\]/g,'').replace(/\+/g,'').replace(/\~/g,'').replace(/\{/g,'').replace(/\*/g,'').replace(/\}/g,'')
if ((num.length < 10) || (num.length > 11) || (num.substring(0,1)=='0') || (num.substring(1,1)=='0') || ((num.length==10)&&(num.substring(0,1)=='1'))||((num.length==11)&&(num.substring(0,1)!='1'))) return false;
num = (num.length == 11) ? num : ('1' + num);
if ((num.length == 11) && (num.substring(0,1) == "1")) {
if (format===true) {
return '(' + num.substr(1,3) + ') ' + num.substr(4,3) + '-' + num.substr(7,4)
} else {
return num
}
} else {
return false;
}
}
Enough is said already on the topic, however to keep it simple, here's my take.
Sorted dictionary should be used when-
On the other side, Sorted List should be used when-
Hope this helps!!
This is more of an xpath question, but like this, assuming the context is the parent element:
<xsl:value-of select="name/@attribute1" />
With latest node.js (v0.3.8-pre): I checked the documentation, inspected the server instance returned by http.createServer(), and read the source code of server.listen()...
Sadly, the port is only stored temporarily as a local variable and ends up as an argument in a call to process.binding('net').bind() which is a native method. I did not look further.
It seems that there is no better way than keeping a reference to the port value that you provided to server.listen().
In my case, it's because a trigger is triggered before a insert cause, (actually it means to split a big table in several tables using timestamp), and then return null. So I met this problem when I used springboot jpa save() function.
In addition to change the trigger to SET NOCOUNT ON;
Mr. TA mentioned above, the solution can also be using native query.
insert into table values(nextval('table_id_seq'), value1)
This doesn't work because NaN
isn't equal to anything, including NaN
. Use pd.isnull(df.var2)
instead.
Starting Python 3.8
, and the introduction of assignment expressions (PEP 572) (:=
operator), which gives the possibility to name the result of an expression, we can use a list comprehension to replicate what other languages call fold/foldleft/reduce operations:
Given a list, a reducing function and an accumulator:
items = [1, 2, 3, 4, 5]
f = lambda acc, x: acc * x
accumulator = 1
we can fold items
with f
in order to obtain the resulting accumulation
:
[accumulator := f(accumulator, x) for x in items]
# accumulator = 120
or in a condensed formed:
acc = 1; [acc := acc * x for x in [1, 2, 3, 4, 5]]
# acc = 120
Note that this is actually also a "scanleft" operation as the result of the list comprehension represents the state of the accumulation at each step:
acc = 1
scanned = [acc := acc * x for x in [1, 2, 3, 4, 5]]
# scanned = [1, 2, 6, 24, 120]
# acc = 120
The ID you are trying is an serverside.
That is going to render in the browser differently.
try to get the ID by watching the html in the Browser.
var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;
this may works.
Or do that ClientID method. That also works but ultimately the browser will get the same thing what i had written.
Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error()
and curl_errno()
will contain further information in case of failure:
try {
$ch = curl_init();
// Check if initialization had gone wrong*
if ($ch === false) {
throw new Exception('failed to initialize');
}
curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt(/* ... */);
$content = curl_exec($ch);
// Check the return value of curl_exec(), too
if ($content === false) {
throw new Exception(curl_error($ch), curl_errno($ch));
}
/* Process $content here */
// Close curl handle
curl_close($ch);
} catch(Exception $e) {
trigger_error(sprintf(
'Curl failed with error #%d: %s',
$e->getCode(), $e->getMessage()),
E_USER_ERROR);
}
* The curl_init()
manual states:
Returns a cURL handle on success, FALSE on errors.
I've observed the function to return FALSE
when you're using its $url
parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE
. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.
One idea i can give is,
Call that function in controller itself and return value to view file. Like,
class Business extends CI_Controller {
public function index() {
$data['css'] = 'profile';
$data['cur_url'] = $this->getCurrURL(); // the function called and store val
$this->load->view("home_view",$data);
}
function getCurrURL() {
$currURL='http://'.$_SERVER['HTTP_HOST'].'/'.ltrim($_SERVER['REQUEST_URI'],'/').'';
return $currURL;
}
}
in view(home_view.php) use that variable. Like,
echo $cur_url;
In Solaris OS I used this command:

I had simillar issue with maven tests on x86 linux which i was using in terminal. I was logging in to linux by ssh. I started my java selenium tests by
mvn -DargLine="-Dbaseurl=http://http://127.0.0.1:8080/web/" install
Excepting my app, after running these tests I received error in logs:
unknown error: Chrome failed to start: exited abnormally
I was running these tests as root user. Before this error i received that ChromeDriver is nor present. I moved forward with this by installing ChromeDriver binary and adding it to PATH. But then i had to install google-chrome browser - ChromeDriver alone isn't enough to run tests. So the mistake is problem maybe with screen buffer in terminal window, but You can install Xvfb which is virtual screen buffer. What is important, that you should run your tests not as root, because you may receive another Chrome Browser error. So no as root i run:
export DISPLAY=:99
Xvfb :99 -ac -screen 0 1280x1024x24 &
What is important here, that in my case the number related to DISPLAY ought to be same as Xvfb :NN parameter. 99 in that case. I had another problem because i ran Xvfb with another DISPLAY value and I wanted it to stop. In order to restart Xvfb:
ps -aux | grep Xvfb
kill -9 PID
sudo rm /tmp/.X11-unix/X99
So find a process PID with grep. Kill Xvfb process. And then there is lock in /tmp/.X11-unix/XNN , so delete this lock and you can start server again. If You run not as root, set simillar displays, install google-chrome then with maven you can start selenium tests. My tests went fine with these rules and operations.
A major difference between them is that value-type variables store values, so specifying a value-type variable in a method call passes a copy of that variable's value to the method. Reference-type variables store references to objects, so specifying a reference-type variable as an argument passes the method a copy of the actual reference that refers to the object. Even though the reference itself is passed by value, the method can still use the reference it receives to interact with—and possibly modify—the original object. Similarly, when returning information from a method via a return statement, the method returns a copy of the value stored in a value-type variable or a copy of the reference stored in a reference-type variable. When a reference is returned, the calling method can use that reference to interact with the referenced object. So, in effect, objects are always passed by reference.
In c#, to pass a variable by reference so the called method can modify the variable's, C# provides keywords ref and out. Applying the ref keyword to a parameter declaration allows you to pass a variable to a method by reference—the called method will be able to modify the original variable in the caller. The ref keyword is used for variables that already have been initialized in the calling method. Normally, when a method call contains an uninitialized variable as an argument, the compiler generates an error. Preceding a parameter with keyword out creates an output parameter. This indicates to the compiler that the argument will be passed into the called method by reference and that the called method will assign a value to the original variable in the caller. If the method does not assign a value to the output parameter in every possible path of execution, the compiler generates an error. This also prevents the compiler from generating an error message for an uninitialized variable that is passed as an argument to a method. A method can return only one value to its caller via a return statement, but can return many values by specifying multiple output (ref and/or out) parameters.

Thanx @krd, I am using your error catch process, but had to update the print and except statements. I am using Python 2.7.6 on Linux Mint 17.2.
Also, it was unclear where the output string was coming from. My update:
import subprocess
# Output returned in error handler
try:
print("Ping stdout output on success:\n" +
subprocess.check_output(["ping", "-c", "2", "-w", "2", "1.1.1.1"]))
except subprocess.CalledProcessError as e:
print("Ping stdout output on error:\n" + e.output)
# Output returned normally
try:
print("Ping stdout output on success:\n" +
subprocess.check_output(["ping", "-c", "2", "-w", "2", "8.8.8.8"]))
except subprocess.CalledProcessError as e:
print("Ping stdout output on error:\n" + e.output)
I see an output like this:
Ping stdout output on error:

--- 1.1.1.1 ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1007ms

I would recommend you look at getting the anaconda package, it will install and configure Sklearn and its dependencies.
You can using the EventLog class, as explained on How to: Write to the Application Event Log (Visual C#):
var appLog = new EventLog("Application");
appLog.Source = "MySource";
appLog.WriteEntry("Test log message");
However, you'll need to configure this source "MySource" using administrative privileges:
Use WriteEvent and WriteEntry to write events to an event log. You must specify an event source to write events; you must create and configure the event source before writing the first entry with the source.
Those are different APIs to access a MySQL backend
So it depends on what kind of code you want to produce. If you prefer object-oriented layers or plain functions...
My advice would be
Also my feeling, the mysql API would probably being deleted in future releases of PHP

Dependency injection is one possible solution to what could generally be termed the "Dependency Obfuscation" requirement. Dependency Obfuscation is a method of taking the 'obvious' nature out of the process of providing a dependency to a class that requires it and therefore obfuscating, in some way, the provision of said dependency to said class. This is not necessarily a bad thing. In fact, by obfuscating the manner by which a dependency is provided to a class then something outside the class is responsible for creating the dependency which means, in various scenarios, a different implementation of the dependency can be supplied to the class without making any changes to the class. This is great for switching between production and testing modes (eg., using a 'mock' service dependency).
Unfortunately the bad part is that some people have assumed you need a specialized framework to do dependency obfuscation and that you are somehow a 'lesser' programmer if you choose not to use a particular framework to do it. Another, extremely disturbing myth, believed by many, is that dependency injection is the only way of achieving dependency obfuscation. This is demonstrably and historically and obviously 100% wrong but you will have trouble convincing some people that there are alternatives to dependency injection for your dependency obfuscation requirements.
Programmers have understood the dependency obfuscation requirement for years and many alternative solutions have evolved both before and after dependency injection was conceived. There are Factory patterns but there are also many options using ThreadLocal where no injection to a particular instance is needed - the dependency is effectively injected into the thread which has the benefit of making the object available (via convenience static getter methods) to any class that requires it without having to add annotations to the classes that require it and set up intricate XML 'glue' to make it happen. When your dependencies are required for persistence (JPA/JDO or whatever) it allows you to achieve 'tranaparent persistence' much easier and with domain model and business model classes made up purely of POJOs (i.e. no framework specific/locked in annotations).
==========Advise==========
@martin clayton Answer is correct, But this is an advise only.
Please avoid the use of ambiguous variable in the stored procedure.
Example :
SELECT Id, dateCreated
INTO id, datecreated
FROM products
WHERE pName = iName
The above example will cause an error (null value error)
Example give below is correct. I hope this make sense.
Example :
SELECT Id, dateCreated
INTO val_id, val_datecreated
FROM products
WHERE pName = iName
You can also make them unambiguous by referencing the table, like:
[ Credit : maganap ]
SELECT p.Id, p.dateCreated INTO id, datecreated FROM products p
WHERE pName = iName
A JavaScript function must first be made that holds what you want to be done:
function print() { console.log("Hello World!") }
and then that function must be called in the onClick method from inside an element:
<a onClick="print()"> ... </a>
You can learn more about modal interactions directly from the Bootstrap 3 documentation found here: http://getbootstrap.com/javascript/#modals
Your modal bind is also incorrect. It should be something like this, where "myModal" = ID of element:
$('#myModal').modal(options)
In other words, if you truly want to keep what you already have, put a "#" in front GSCCModal and see if that works.
It is also not very wise to have an onClick bound to a div element; something like a button would be more suitable.
Hope this helps!

To remove - Can't perform a React state update on an unmounted component warning, use componentDidMount method under a condition and make false that condition on componentWillUnmount method. For example : -
class Home extends Component {
_isMounted = false;
constructor(props) {
super(props);
this.state = {
news: [],
};
}
componentDidMount() {
this._isMounted = true;
ajaxVar
.get('https://domain')
.then(result => {
if (this._isMounted) {
this.setState({
news: result.data.hits,

}
});
}
componentWillUnmount() {
this._isMounted = false;
}
render() {

Inorder to take thread dump/heap dump from a child java process in windows, you need to identify the child process Id as first step.
By issuing the command: jps you will be able get all java process Ids that are running on your windows machine. From this list you need to select child process Id. Once you have child process Id, there are various options to capture thread dump and heap dumps.
Capturing Thread Dumps:
There are 8 options to capture thread dumps:
Details about each option can be found in this article. Once you have capture thread dumps, you can use tools like fastThread, Samuraito analyze thread dumps.
Capturing Heap Dumps:
There are 7 options to capture heap dumps:
jmap
-XX:+HeapDumpOnOutOfMemoryError
jcmd
JVisualVM
JMX
Programmatic Approach
Administrative consoles
Details about each option can be found in this article. Once you have captured heap dump, you may use tools like Eclipse Memory Analysis tool, HeapHero to analyze the captured heap dumps.
I also got same error, compiling with -D flag fixed it, Try this:
g++ -Dstd=c++11
Follow up any question like this with: "How could you improve this code so the developer who maintains it can figure out how it works easily?"
$("#registerSubmit").serialize() // returns all the data in your form
$.ajax({
type: "POST",
url: 'your url',
data: $("#registerSubmit").serialize(),
success: function() {
//success message mybe...
}
});
Well, you already have good answers, but they're most Lambda. A more LINQ approach would be like
var NotSentMessages =
from msg in MsgList
where !SentList.Any(x => x.MsgID == msg.MsgID)
select msg;
String text = "text";
text += new String(" ");
As Tim Williams suggested, using Application.VLookup
will not throw an error if the lookup value is not found (unlike Application.WorksheetFunction.VLookup
).
If you want the lookup to return a default value when it fails to find a match, and to avoid hard-coding the column number -- an equivalent of IFERROR(VLOOKUP(what, where, COLUMNS(where), FALSE), default)
in formulas, you could use the following function:
Private Function VLookupVBA(what As Variant, lookupRng As Range, defaultValue As Variant) As Variant
Dim rv As Variant: rv = Application.VLookup(what, lookupRng, lookupRng.Columns.Count, False)
If IsError(rv) Then
VLookupVBA = defaultValue
Else
VLookupVBA = rv
End If
End Function
Public Sub UsageExample()
MsgBox VLookupVBA("ValueToFind", ThisWorkbook.Sheets("ReferenceSheet").Range("A:D"), "Not found!")
End Sub
Actually you don't need "install" or "compile" anything before using Boost in your project. You can just download and extract the Boost library to any location on your machine, which is usually like /usr/local/
.
When you compile your code, you can just indicate the compiler where to find the libraries by -I
. For example, g++ -I /usr/local/boost_1_59_0 xxx.hpp
.
How about using a simple loop to count the occurrences of number of spaces!?
txt = "Just an example here move along" _x000D_
count = 1_x000D_
for i in txt:_x000D_
if i == " ":_x000D_
count += 1_x000D_
print(count)
_x000D_
The issue is simple, npm
doesn't know about ng
Just run npm link @angular/cli
and it should work seamlessly.
With Aspose.Cells library for .NET, you can easily export data of specific rows and columns from one Excel document to another. The following code sample shows how to do this in C# language.
// Open the source excel file.
Workbook srcWorkbook = new Workbook("Source_Workbook.xlsx");
// Create the destination excel file.
Workbook destWorkbook = new Workbook();
// Get the first worksheet of the source workbook.
Worksheet srcWorksheet = srcWorkbook.Worksheets[0];
// Get the first worksheet of the destination workbook.
Worksheet desWorksheet = destWorkbook.Worksheets[0];
// Copy the second row of the source Workbook to the first row of destination Workbook.
desWorksheet.Cells.CopyRow(srcWorksheet.Cells, 1, 0);
// Copy the fourth row of the source Workbook to the second row of destination Workbook.
desWorksheet.Cells.CopyRow(srcWorksheet.Cells, 3, 1);
// Save the destination excel file.
destWorkbook.Save("Destination_Workbook.xlsx");
The following blog post explains in detail how to export data from different sources to an Excel document.
https://blog.conholdate.com/2020/08/10/export-data-to-excel-in-csharp/
you can use toSource method like this
alert(product.toSource());
This is old, but someone else may stumble on it as I did. When you connect to the DataCast, you are talking to a daemon that can access the database. It was intended that a customer would write some code to access the database and store the results somewhere. It just happens that telnet works to access data manually. netcat should also work. ssh obviously will not.
You can grab the command line of any .Net application by accessing the Environment.CommandLine property. It will have the command line as a single string but parsing out the data you are looking for shouldn't be terribly difficult.
Having an empty Main method will not affect this property or the ability of another program to add a command line parameter.
"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
Reference: http://www.cyberciti.biz/faq/linux-unix-bash-for-loop-one-line-command/
You can avoid making a copy of the object using Wen's solution and inplace=True:
df.fillna({'a':0, 'b':0}, inplace=True)
print(df)
Which yields:
a b c
0 1.0 4.0 NaN
1 2.0 5.0 NaN
2 3.0 0.0 7.0
3 0.0 6.0 8.0
To replace anything that starts with "text" until the last character:
text.+(.*)$
Example
text hsjh sdjh sd jhsjhsdjhsdj hsd ^ last character
text.+(\ 123)
Example
text fuhfh283nfnd03no3 d90d3nd 3d 123 udauhdah au dauh ej2e ^ ^ From here To here
It depends. Switch evaluates once and only once. Upon a match, all subsequent case statements until 'break' fire no matter what the case says.

You must enable the library GD2.
Find your (proper) php.ini file
Find the line: ;extension=php_gd2.dll and remove the semicolon in the front.
The line should look like this:
extension=php_gd2.dll
Then restart apache and you should be good to go.
Use the display property
a{
display: block;
}
This will make the link to display in new line
If you want to remove list styling, use
li{
list-style: none;
}
It is, but requires a CSS2 capable browser (all major browsers, IE8+).
.OwnerJoe:before {
content: "Joe's Task:";
}
But I would rather recommend using Javascript for this. With jQuery:
$('.OwnerJoe').each(function() {
$(this).before($('<span>').text("Joe's Task: "));
});
I came across ParamUnittest the other day when looking at the source code for radon (example usage on the GitHub repository). It should work with other frameworks that extend TestCase (like Nose).
Here is an example:
import unittest
import paramunittest
@paramunittest.parametrized(
('1', '2'),
#(4, 3), <---- Uncomment to have a failing test
('2', '3'),
(('4', ), {'b': '5'}),
((), {'a': 5, 'b': 6}),
{'a': 5, 'b': 6},
)
class TestBar(TestCase):
def setParameters(self, a, b):
self.a = a
self.b = b
def testLess(self):
self.assertLess(self.a, self.b)
Select URColumnName From URTableName Where length(URColumnName ) IN
(Select max(length(URColumnName)) From URTableName);
This will give you the records in that particular column which has the maximum length.
use base_url()
echo $baseurl=base_url();
if you need to pass url to a function then use site_url()
echo site_url('controller/function');
if you need the root path then FCPATH
..
echo FCPATH;
See explanation here.
The Callable interface is similar to Runnable, in that both are designed for classes whose instances are potentially executed by another thread. A Runnable, however, does not return a result and cannot throw a checked exception.
ImageView img = (ImageView) findViewById(R.id.myImageId);
img.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// your code here
}
});
The new way to do this is a lot more simple and will save you some time! Just pass the event into the original click handler and call preventDefault();
.
clickHandler(e){
e.preventDefault();
//Your functionality here
}
I describe one solution for iOS 4.2+ here but the dismiss button fades in after the keyboard appears. It's not terrible, but not ideal either.
The solution described in the question linked above includes a more elegant illusion to dismiss the button, where I fade and vertically displace the button to provide the appearance that the keypad and the button are dismissing together.
setAutoSize method must come before setWidth:
$objPHPExcel->getActiveSheet()->getColumnDimensionByColumn('C')->setAutoSize(false);
$objPHPExcel->getActiveSheet()->getColumnDimensionByColumn('C')->setWidth('10');
Here is how to get the Guid's programmatically! You can then use these guids/filepaths with an above answer to add the reference!
Reference: http://www.vbaexpress.com/kb/getarticle.php?kb_id=278
Sub ListReferencePaths()
'Lists path and GUID (Globally Unique Identifier) for each referenced library.
'Select a reference in Tools > References, then run this code to get GUID etc.
Dim rw As Long, ref
With ThisWorkbook.Sheets(1)
.Cells.Clear
rw = 1
.Range("A" & rw & ":D" & rw) = Array("Reference","Version","GUID","Path")
For Each ref In ThisWorkbook.VBProject.References
rw = rw + 1
.Range("A" & rw & ":D" & rw) = Array(ref.Description, _
"v." & ref.Major & "." & ref.Minor, ref.GUID, ref.FullPath)
Next ref
.Range("A:D").Columns.AutoFit
End With
End Sub
Here is the same code but printing to the terminal if you don't want to dedicate a worksheet to the output.
Sub ListReferencePaths()
'Macro purpose: To determine full path and Globally Unique Identifier (GUID)

Why don't you go for null handling functions through application programs, it is better alternative.
Synchronize the data/object that you have saved into NSUserDefaults
-(void)saveCustomObject:(Player *)object
{
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSData *myEncodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
[prefs setObject:myEncodedObject forKey:@"testing"];
[prefs synchronize];
}
Hope this will help you. Thanks
If you do not need to add a border on columns, you can also simply add a transparent border on them:
[class*="col-"] {
background-clip: padding-box;
border: 10px solid transparent;
}
Try this one, it will broadcast about a new image created, so your image visible. inside a gallery. photoFile replace with actual file path of the newly created image
private void galleryAddPicBroadCast() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(photoFile);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
By default require()
is not a valid function in client side javascript. I recommend you look into require.js as this does extend the client side to provide you with that function.
Necromancing.
I assume when somebody lands here, he needs a foreign key to column in a table that contains non-unique keys.
The problem is, that if you have that problem, the database-schema is denormalized.
You're for example keeping rooms in a table, with a room-uid primary key, a DateFrom and a DateTo field, and another uid, here RM_ApertureID to keep track of the same room, and a soft-delete field, like RM_Status, where 99 means 'deleted', and <> 99 means 'active'.
So when you create the first room, you insert RM_UID and RM_ApertureID as the same value as RM_UID. Then, when you terminate the room to a date, and re-establish it with a new date range, RM_UID is newid(), and the RM_ApertureID from the previous entry becomes the new RM_ApertureID.
So, if that's the case, RM_ApertureID is a non-unique field, and so you can't set a foreign-key in another table.
And there is no way to set a foreign key to a non-unique column/index, e.g. in T_ZO_REM_AP_Raum_Reinigung (WHERE RM_UID is actually RM_ApertureID).
But to prohibit invalid values, you need to set a foreign key, otherwise, data-garbage is the result sooner rather than later...
Now what you can do in this case (short of rewritting the entire application) is inserting a CHECK-constraint, with a scalar function checking the presence of the key:
IF EXISTS (SELECT * FROM sys.check_constraints WHERE object_id = OBJECT_ID(N'[dbo].[Check_RM_ApertureIDisValid_T_ZO_REM_AP_Raum_Reinigung]') AND parent_object_id = OBJECT_ID(N'[dbo].[T_ZO_REM_AP_Raum_Reinigung]'))

The first answer is almost correct, but what is needed is to change getter method, NOT field -- field is private (and not auto-detected); further, getters have precedence over fields if both are visible.(There are ways to make private fields visible, too, but if you want to have getter there's not much point)
So getter should either be named getWrapper()
, or annotated with:
@JsonProperty("wrapper")
If you prefer getter method name as is.
For practically all date and time matters I prefer to simplify things, very, very simple... Down to seconds stored in integers.
Integers will always be supported as integers in databases, flat files, etc. You do a little math and cast it into another type and you can format the date anyway you want.
Doing it this way, you don't have to worry when [insert current favorite database here] is replaced with [future favorite database] which coincidentally didn't use the date format you chose today.
It's just a little math overhead (eg. methods--takes two seconds, I'll post a gist if necessary) and simplifies things for a lot of operations regarding date/time later.
You can also export the database and then use a program like notepad++ to replace words and then inmport aigain.
the thing that work for me was to set /etc/hosts to point the hostname to the ip and not to the loopback interface and than restart my application.
cat /etc/hosts
127.0.0.1 localhost.localdomain localhost

First argument in update
method is SyntheticEvent
object that contains common properties and methods to any event
, it is not reference to React component where there is property props
.
if you need pass argument to update method you can do it like this
onClick={ (e) => this.props.onClick(e, 'home', 'Home') }
and get these arguments inside update
method
update(e, space, txt){
console.log(e.target, space, txt);
}
event.target
gives you the native DOMNode
, then you need to use the regular DOM APIs to access attributes. For instance getAttribute
or dataset
<button
data-space="home"
className="home"
data-txt="Home"
onClick={ this.props.onClick }
/>
Button
</button>
onClick(e) {
console.log(e.target.dataset.txt, e.target.dataset.space);
}
If your query consists only of the $where
operator, you can pass in just the JavaScript expression:
db.T.find("this.Grade1 > this.Grade2");
For greater performance, run an aggregate operation that has a $redact
pipeline to filter the documents which satisfy the given condition.
The $redact
pipeline incorporates the functionality of $project
and $match
to implement field level redaction where it will return all documents matching the condition using $$KEEP
and removes from the pipeline results those that don't match using the $$PRUNE
variable.
Running the following aggregate operation filter the documents more efficiently than using $where
for large collections as this uses a single pipeline and native MongoDB operators, rather than JavaScript evaluations with $where
, which can slow down the query:
db.T.aggregate([
{
"$redact": {
"$cond": [
{ "$gt": [ "$Grade1", "$Grade2" ] },
"$$KEEP",
"$$PRUNE"
]
}
}
])
which is a more simplified version of incorporating the two pipelines $project
and $match
:
db.T.aggregate([
{
"$project": {
"isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] },
"Grade1": 1,
"Grade2": 1,
"OtherFields": 1,
...
}
},
{ "$match": { "isGrade1Greater": 1 } }
])
With MongoDB 3.4 and newer:
db.T.aggregate([
{
"$addFields": {
"isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] }
}
},
{ "$match": { "isGrade1Greater": 1 } }
])
Bash 4 natively supports this feature. Make sure your script's hashbang is #!/usr/bin/env bash
or #!/bin/bash
so you don't end up using sh
. Make sure you're either executing your script directly, or execute script
with bash script
. (Not actually executing a Bash script with Bash does happen, and will be really confusing!)
You declare an associative array by doing:
declare -A animals
You can fill it up with elements using the normal array assignment operator. For example, if you want to have a map of animal[sound(key)] = animal(value)
:
animals=( ["moo"]="cow" ["woof"]="dog")
Or merge them:
declare -A animals=( ["moo"]="cow" ["woof"]="dog")
Then use them just like normal arrays. Use
animals['key']='value'
to set value
"${animals[@]}"
to expand the values
"${!animals[@]}"
(notice the !
) to expand the keys
Don't forget to quote them:
echo "${animals[moo]}"
for sound in "${!animals[@]}"; do echo "$sound - ${animals[$sound]}"; done
Before bash 4, you don't have associative arrays. Do not use eval
to emulate them. Avoid eval
like the plague, because it is the plague of shell scripting. The most important reason is that eval
treats your data as executable code (there are many other reasons too).
First and foremost: Consider upgrading to bash 4. This will make the whole process much easier for you.
If there's a reason you can't upgrade, declare
is a far safer option. It does not evaluate data as bash code like eval
does, and as such does not allow arbitrary code injection quite so easily.
Let's prepare the answer by introducing the concepts:
First, indirection.
$ animals_moo=cow; sound=moo; i="animals_$sound"; echo "${!i}"
cow
Secondly, declare
:
$ sound=moo; animal=cow; declare "animals_$sound=$animal"; echo "$animals_moo"
cow
Bring them together:
# Set a value:
declare "array_$index=$value"
# Get a value:
arrayGet() {
local array=$1 index=$2
local i="${array}_$index"
printf '%s' "${!i}"
}
Let's use it:
$ sound=moo
$ animal=cow
$ declare "animals_$sound=$animal"
$ arrayGet animals "$sound"
cow
Note: declare
cannot be put in a function. Any use of declare
inside a bash function turns the variable it creates local to the scope of that function, meaning we can't access or modify global arrays with it. (In bash 4 you can use declare -g to declare global variables - but in bash 4, you can use associative arrays in the first place, avoiding this workaround.)
Summary:
declare -A
for associative arrays.declare
option if you can't upgrade.awk
instead and avoid the issue altogether.You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.
Because you do not provide any context or code for your question it is not possible to give a direct answer.
I suggest you study how unicode and character encoding is done in Python:
Valentin Rocher's method works if you've extended your view, but if you're using an event listener, use this:
view.setOnTouchListener(new OnTouchListener()
{
public boolean onTouch(View v, MotionEvent event)
{
Toast toast = Toast.makeText(
getApplicationContext(),
"View touched",
Toast.LENGTH_LONG
);
toast.show();
return true;
}
});
// Obtain MotionEvent object
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis() + 100;
float x = 0.0f;
float y = 0.0f;
// List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
int metaState = 0;
MotionEvent motionEvent = MotionEvent.obtain(
downTime,
eventTime,
MotionEvent.ACTION_UP,
x,
y,
metaState
);
// Dispatch touch event to view
view.dispatchTouchEvent(motionEvent);
For more on obtaining a MotionEvent object, here is an excellent answer: Android: How to create a MotionEvent?

You just need to use single quotes:
$ echo "$TEST"
test
$ echo '$TEST'
$TEST
Inside single quotes special characters are not special any more, they are just normal characters.
Almost every to-ISO method on the web drops the timezone information by applying a convert to "Z"ulu time (UTC) before outputting the string. Browser's native .toISOString() also drops timezone information.
This discards valuable information, as the server, or recipient, can always convert a full ISO date to Zulu time or whichever timezone it requires, while still getting the timezone information of the sender.
The best solution I've come across is to use the Moment.js javascript library and use the following code:
To get the current ISO time with timezone information and milliseconds
now = moment().format("YYYY-MM-DDTHH:mm:ss.SSSZZ")
// "2013-03-08T20:11:11.234+0100"
now = moment().utc().format("YYYY-MM-DDTHH:mm:ss.SSSZZ")
// "2013-03-08T19:11:11.234+0000"
now = moment().utc().format("YYYY-MM-DDTHH:mm:ss") + "Z"
// "2013-03-08T19:11:11Z" <- better use the native .toISOString()
To get the ISO time of a native JavaScript Date object with timezone information but without milliseconds
var current_time = Date.now();
moment(current_time).format("YYYY-MM-DDTHH:mm:ssZZ")
This can be combined with Date.js to get functions like Date.today() whose result can then be passed to moment.
A date string formatted like this is JSON compilant, and lends itself well to get stored into a database. Python and C# seem to like it.
Markus has one way to avoid using the word for

Here is how you would add query string parameters using HttpClient 4.2 and later:
URIBuilder builder = new URIBuilder("http://example.com/");
builder.setParameter("parts", "all").setParameter("action", "finish");
HttpPost post = new HttpPost(builder.build());
The resulting URI would look like:
http://example.com/?parts=all&action=finish
If by "cursor speed", you mean the repeat rate when holding down a key - then have a look here: http://hints.macworld.com/article.php?story=20090823193018149
To summarize, open up a Terminal window and type the following command:
defaults write NSGlobalDomain KeyRepeat -int 0
More detail from the article:
Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:
defaults write NSGlobalDomain KeyRepeat -int 0
Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.
You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.
this is how I implement it .

!== is the strict not equal operator and only returns a value of true if both the operands are not equal and/or not of the same type. The following examples return a Boolean true:
a !== b
a !== "2"

In regards to your error and what's missing in your code. m
is a name which is not defined for getmd5()
function.
No offence, I know you are a beginner, but your code is all over the place. Let's look at your issues one by one :)
First, you are not using hashlib.md5.hexdigest()
method correctly. Please refer explanation on hashlib functions in Python Doc Library. The correct way to return MD5 for provided string is to do something like this:
>>> import hashlib
>>> hashlib.md5("filename.exe").hexdigest()
'2a53375ff139d9837e93a38a279d63e5'
However, you have a bigger problem here. You are calculating MD5 on a file name string, where in reality MD5 is calculated based on file contents. You will need to basically read file contents and pipe it though MD5. My next example is not very efficient, but something like this:
>>> import hashlib
>>> hashlib.md5(open('filename.exe','rb').read()).hexdigest()
'd41d8cd98f00b204e9800998ecf8427e'
As you can clearly see second MD5 hash is totally different from the first one. The reason for that is that we are pushing contents of the file through, not just file name.
A simple solution could be something like that:
# Import hashlib library (md5 method is part of it)
import hashlib
# File to check
file_name = 'filename.exe'
# Correct original md5 goes here
original_md5 = '5d41402abc4b2a76b9719d911017c592'
# Open,close, read file and calculate MD5 on its contents
with open(file_name) as file_to_check:
# read contents of the file
data = file_to_check.read()
# pipe contents of the file through
md5_returned = hashlib.md5(data).hexdigest()
# Finally compare original MD5 with freshly calculated
if original_md5 == md5_returned:
print "MD5 verified."
else:
print "MD5 verification failed!."
Please look at the post Python: Generating a MD5 checksum of a file. It explains in detail a couple of ways how it can be achieved efficiently.
Best of luck.

undefined index means in an array you requested for unavailable array index for example
<?php
$newArray[] = {1,2,3,4,5};
print_r($newArray[5]);
?>
undefined variable means you have used completely not existing variable or which is not defined or initialized by that name for example
<?php print_r($myvar); ?>
undefined offset means in array you have asked for non existing key. And the solution for this is to check before use
php> echo array_key_exists(1, $myarray);
Quick review,
From x86 assembly tutorial,
The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.
Your num is 1 byte. Try declaring it with DD
so that it becomes 4 bytes and matches with pop
semantics.

Your submission will cancel the redirect or vice versa.
I do not see the reason for the redirect in the first place since why do you have an order form that does nothing.
That said, here is how to do it. Firstly NEVER put code on the submit button but do it in the onsubmit, secondly return false to stop the submission
NOTE This code will IGNORE the action and ONLY execute the script due to the return false/preventDefault
function redirect() {
window.location.replace("login.php");
return false;
}
using
<form name="form1" id="form1" method="post" onsubmit="return redirect()">
<input type="submit" class="button4" name="order" id="order" value="Place Order" >
</form>
Or unobtrusively:
window.onload=function() {
document.getElementById("form1").onsubmit=function() {
window.location.replace("login.php");
return false;
}
}
using
<form id="form1" method="post">
<input type="submit" class="button4" value="Place Order" >
</form>
jQuery:
$("#form1").on("submit",function(e) {
e.preventDefault(); // cancel submission
window.location.replace("login.php");
});
Example:
$("#form1").on("submit", function(e) {_x000D_
e.preventDefault(); // cancel submission_x000D_
alert("this could redirect to login.php"); _x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<form id="form1" method="post" action="javascript:alert('Action!!!')">_x000D_
<input type="submit" class="button4" value="Place Order">_x000D_
</form>
_x000D_

List<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia)); //copy
In this case, list1
is of type ArrayList
.
List<Integer> list2 = Arrays.asList(ia);
Here, the list is returned as a List
view, meaning it has only the methods attached to that interface. Hence why some methods are not allowed on list2
.
ArrayList<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia));
Here, you ARE creating a new ArrayList
. You're simply passing it a value in the constructor. This is not an example of casting. In casting, it might look more like this:
ArrayList list1 = (ArrayList)Arrays.asList(ia);

Here you can also find more examples for values that data-toggle
can have assigned. Just visit the page and then CTRL+F
to search for data-toggle
.
For example, if you want an array of int
pointers it will be int* a[10]
. It means that variable a
is a collection of 10 int*
s.
EDIT
I guess this is what you want to do:
class Bar
{
};
class Foo
{
public:
//Takes number of bar elements in the pointer array
Foo(int size_in);
~Foo();
void add(Bar& bar);
private:
//Pointer to bar array
Bar** m_pBarArr;
//Current fee bar index
int m_index;
};
Foo::Foo(int size_in) : m_index(0)
{
//Allocate memory for the array of bar pointers
m_pBarArr = new Bar*[size_in];
}
Foo::~Foo()
{
//Notice delete[] and not delete
delete[] m_pBarArr;
m_pBarArr = NULL;
}
void Foo::add(Bar &bar)
{
//Store the pointer into the array.
//This is dangerous, you are assuming that bar object
//is valid even when you try to use it
m_pBarArr[m_index++] = &bar;
}
Chris Nielsen's solution is simple and will work well. A slightly shorter option would be...
ws.Rows(Rand).Delete
...note there is no need to specify a Shift when deleting a row as, by definition, it's not possible to shift left
Incidentally, my preferred method for deleting rows is to use...
ws.Rows(Rand) = ""
...in the initial loop. I then use a Sort function to push these rows to the bottom of the data. The main reason for this is because deleting single rows can be a very slow procedure (if you are deleting >100). It also ensures nothing gets missed as per Robert Ilbrink's comment
You can learn the code for sorting by recording a macro and reducing the code as demonstrated in this expert Excel video. I have a suspicion that the neatest method (Range("A1:Z10").Sort Key1:=Range("A1"), Order1:=xlSortAscending/Descending, Header:=xlYes/No) can only be discovered on pre-2007 versions of Excel...but you can always reduce the 2007/2010 equivalent code
Couple more points...if your list is not already sorted by a column and you wish to retain the order, you can stick the row number 'Rand' in a spare column to the right of each row as you loop through. You would then sort by that comment and eliminate it
If your data rows contain formatting, you may wish to find the end of the new data range and delete the rows that you cleared earlier. That's to keep the file size down. Note that a single large delete at the end of the procedure will not impair your code's performance in the same way that deleting single rows does
Following is the list of conversion characters that you may use in the printf:
%d – for signed decimal integer
%f – for the floating point
%o – octal number
%c – for a character
%s – a string
%i – use for integer base 10
%u – for unsigned decimal number
%x – hexadecimal number
%% – for writing % (percentage)
%n – for new line = \n
To remove cached .idea/ directory.
e.g. git rm -r --cached .idea
http.get(options).on('response', function (response) {
var body = '';
var i = 0;
response.on('data', function (chunk) {
i++;
body += chunk;
console.log('BODY Part: ' + i);
});
response.on('end', function () {
console.log(body);
console.log('Finished');
});
});
Changes to this, which works. Any comments?
Ubuntu has a very simple way to manage a service. For python the difference is that ALL the dependencies (packages) have to be in the same directory, where the main file is run from.
I just manage to create such a service to provide weather info to my clients. Steps:
Create your python application project as you normally do.
Install all dependencies locally like: sudo pip3 install package_name -t .
Create your command line variables and handle them in code (if you need any)
Create the service file. Something (minimalist) like:
[Unit]
Description=1Droid Weather meddleware provider
[Service]
Restart=always
User=root
WorkingDirectory=/home/ubuntu/weather
ExecStart=/usr/bin/python3 /home/ubuntu/weather/main.py httpport=9570 provider=OWMap
[Install]
WantedBy=multi-user.target
Save the file as myweather.service (for example)
Make sure that your app runs if started in the current directory
python3 main.py httpport=9570 provider=OWMap
The service file produced above and named myweather.service (important to have the extension .service) will be treated by the system as the name of your service. That is the name that you will use to interact with your service.
Copy the service file:
sudo cp myweather.service /lib/systemd/system/myweather.service
Refresh demon registry:
sudo systemctl daemon-reload
Stop the service (if it was running)
sudo service myweatherr stop
Start the service:
sudo service myweather start
Check the status (log file with where your print statements go):
tail -f /var/log/syslog
Or check the status with:
sudo service myweather status
Back to the start with another iteration if needed
This service is now running and even if you log out it will not be affected. And YES if the host is shutdown and restarted this service will be restarted...information for my mobile android app...
Just as Jake Wilson said: You can set the connection to a variable then disconnect it when you are done:
let db;
mongoose.connect('mongodb://localhost:27017/somedb').then((dbConnection)=>{
db = dbConnection;
afterwards();
});
function afterwards(){
//do stuff
db.disconnect();
}
or if inside Async function:
(async ()=>{
const db = await mongoose.connect('mongodb://localhost:27017/somedb', { useMongoClient:
true })
//do stuff
db.disconnect()
})
otherwise when i was checking it in my environment it has an error.
Use Where-Object
, like:
Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") |
Where-Object { $_.CreationTime -gt "03/01/2013" -and $_.CreationTime -lt "03/31/2013" }
Select-Object FullName, CreationTime, @{Name="Mbytes";Expression={$_.Length/1Kb}}, @{Name="Age";Expression={(((Get-Date) - $_.CreationTime).Days)}} |
Export-Csv 'PATH\scans.csv'
MSSQL Query

where datetable.Date between '2014-01-20' and '2014-01-24'
order by datetable.Date DESC
Output

you can only make circle from square using border-radius.
border-radius doesn't increase or reduce heights nor widths.
Your request is to use only image tag , it is basicly not possible if tag is not a square.
If you want to use a blank image and set another in bg, it is going to be painfull , one background for each image to set.
Cropping can only be done if a wrapper is there to do so. inthat case , you have many ways to do it
Using Node.js
sync mode:
var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")
async mode:
var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
var textByLine = text.split("\n")
});
UPDATE
As of at least Node 6, readFileSync
returns a Buffer
, so it must first be converted to a string in order for split
to work:
var text = fs.readFileSync("./mytext.txt").toString('utf-8');
Or
var text = fs.readFileSync("./mytext.txt", "utf-8");
You shouldn't really do this but insert in a new record instead and update it that way.
But, if you really need to, you can do the following:
ALTER TABLE foo WITH NOCHECK CONSTRAINT ALL
)Python shouldn't crash when you call getdata(). The image might be corrupted or there is something wrong with your PIL installation. Try it with another image or post the image you are using.
This should break down the image the way you want:
from PIL import Image
im = Image.open('um_000000.png')
pixels = list(im.getdata())
width, height = im.size
pixels = [pixels[i * width:(i + 1) * width] for i in xrange(height)]
Try to use anyMatch
of Lambda Expression. It is much better approach.
boolean idExists = tabPane.getTabs().stream()
.anyMatch(t -> t.getId().equals(idToCheck));
A static method can NOT access a Non-static method or variable.
public static void main(String[] args)
is a static method, so can NOT access the Non-static public static int fxn(int y)
method.
Try it this way...
static int fxn(int y)
public class Two {
public static void main(String[] args) {
int x = 0;
System.out.println("x = " + x);
x = fxn(x);
System.out.println("x = " + x);
}
static int fxn(int y) {
y = 5;
return y;
}
}
When an object in a TempDataDictionary
is read, it will be marked for deletion at the end of that request.
That means if you put something on TempData like
TempData["value"] = "someValueForNextRequest";
And on another request you access it, the value will be there but as soon as you read it, the value will be marked for deletion:
//second request, read value and is marked for deletion
object value = TempData["value"];
//third request, value is not there as it was deleted at the end of the second request
TempData["value"] == null
The Peek
and Keep
methods allow you to read the value without marking it for deletion. Say we get back to the first request where the value was saved to TempData.
With Peek
you get the value without marking it for deletion with a single call, see msdn:
//second request, PEEK value so it is not deleted at the end of the request
object value = TempData.Peek("value");
//third request, read value and mark it for deletion
object value = TempData["value"];
With Keep
you specify a key that was marked for deletion that you want to keep. Retrieving the object and later on saving it from deletion are 2 different calls. See msdn
//second request, get value marking it from deletion
object value = TempData["value"];
//later on decide to keep it
TempData.Keep("value");
//third request, read value and mark it for deletion
object value = TempData["value"];
You can use Peek
when you always want to retain the value for another request. Use Keep
when retaining the value depends on additional logic.
You have 2 good questions about how TempData works here and here
Hope it helps!
First make sure s1
and s2
are of the same length. Then check to see if s2
is a substring of s1
concatenated with s1
:
algorithm checkRotation(string s1, string s2)
if( len(s1) != len(s2))
return false
if( substring(s2,concat(s1,s1))
return true
return false
end
In Java:
boolean isRotation(String s1,String s2) {
return (s1.length() == s2.length()) && ((s1+s1).indexOf(s2) != -1);
}

Remove every file from Git's index.
git rm --cached -r .
Rewrite the Git index to pick up all the new line endings.
git reset --hard
Note that step 2 may remove your local changes. Solution was part of steps described on git site https://help.github.com/articles/dealing-with-line-endings/
Something like this could be it?
<div class="random">
SOMETHING
</div>
body{
text-align: center;
}
.random{
width: 60%;
margin: auto;
background-color: yellow;
display:block;
}
DEMO: http://jsfiddle.net/t5Pp2/2/
Edit: adding display:block
doesn't ruin the thing, so...
You can also set the margin to: margin: 0 auto 0 auto;
just to be sure it centers only this way not from the top too.
select count(*)
from table_emp
where DATEPART(YEAR, ARR_DATE) = '2012' AND DATEPART(MONTH, ARR_DATE) = '01'
Objective-C:
[label setFont: [label.font fontWithSize: sizeYouWant]];
Swift:
label.font = label.font.fontWithSize(sizeYouWant)
just changes font size of a UILabel.
As Fred mentioned, there is no way to natively style radio buttons in regards to color, size, etcc. But you can use CSS Pseudo elements to setup an impostor of any given radio button, and style it. Touching on what JamieD said, on how we can use the :after Pseudo element, you can use both :before and :after to achieve a desirable look.
Benefits of this approach:

A short demo to see it in action
In conclusion, no JavaScript, images or batteries required. Pure CSS.
You can do that using at. You can try out the following simple example:
const size_t N = 20;
std::vector<int> vec(N);
try {
vec.at(N - 1) = 7;
} catch (std::out_of_range ex) {
std::cout << ex.what() << std::endl;
}
assert(vec.at(N - 1) == 7);
Notice that method at
returns an allocator_type::reference
, which is that case is a int&
. Using at
is equivalent to assigning values like vec[i]=...
.
There is a difference between at
and insert as it can be understood with the following example:
const size_t N = 8;
std::vector<int> vec(N);
for (size_t i = 0; i<5; i++){
vec[i] = i + 1;
}
vec.insert(vec.begin()+2, 10);
If we now print out vec
we will get:
1 2 10 3 4 5 0 0 0
If, instead, we did vec.at(2) = 10
, or vec[2]=10
, we would get
1 2 10 4 5 0 0 0
Well, after researching and fighting with the problem for hours, I found out that there are two ways to accomplish this, depending on the structure of your table and if you have foreign keys restrictions activated to maintain integrity. I'd like to share this in a clean format to save some time to the people that may be in my situation.
In other words, you don't have foreign key, or if you have them, your SQLite engine is configured so that there no are integrity exceptions. The way to go is INSERT OR REPLACE. If you are trying to insert/update a player whose ID already exists, the SQLite engine will delete that row and insert the data you are providing. Now the question comes: what to do to keep the old ID associated?
Let's say we want to UPSERT with the data user_name='steven' and age=32.
Look at this code:
INSERT INTO players (id, name, age)
VALUES (
coalesce((select id from players where user_name='steven'),
(select max(id) from drawings) + 1),
32)
The trick is in coalesce. It returns the id of the user 'steven' if any, and otherwise, it returns a new fresh id.
After monkeying around with the previous solution, I realized that in my case that could end up destroying data, since this ID works as a foreign key for other table. Besides, I created the table with the clause ON DELETE CASCADE, which would mean that it'd delete data silently. Dangerous.
So, I first thought of a IF clause, but SQLite only has CASE. And this CASE can't be used (or at least I did not manage it) to perform one UPDATE query if EXISTS(select id from players where user_name='steven'), and INSERT if it didn't. No go.
And then, finally I used the brute force, with success. The logic is, for each UPSERT that you want to perform, first execute a INSERT OR IGNORE to make sure there is a row with our user, and then execute an UPDATE query with exactly the same data you tried to insert.
Same data as before: user_name='steven' and age=32.
-- make sure it exists
INSERT OR IGNORE INTO players (user_name, age) VALUES ('steven', 32);
-- make sure it has the right data
UPDATE players SET user_name='steven', age=32 WHERE user_name='steven';
And that's all!
As Andy has commented, trying to insert first and then update may lead to firing triggers more often than expected. This is not in my opinion a data safety issue, but it is true that firing unnecessary events makes little sense. Therefore, a improved solution would be:
-- Try to update any existing row
UPDATE players SET age=32 WHERE user_name='steven';
-- Make sure it exists
INSERT OR IGNORE INTO players (user_name, age) VALUES ('steven', 32);
Like this:
{% if age > 18 %}
{% with patient as p %}
<my html here>
{% endwith %}
{% else %}
{% with patient.parent as p %}
<my html here>
{% endwith %}
{% endif %}
If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:
p = (age > 18 && patient) or patient.parent
and then just use {{ p }} in the template.
You can absolutely position pseudo elements
relative to their parent element.
This gives you two extra layers to play with for every element - so positioning one image on top of another becomes easy - with minimal and semantic markup (no empty divs etc).
markup:
<div class="overlap"></div>
css:
.overlap
{
width: 100px;
height: 100px;
position: relative;
background-color: blue;
}
.overlap:after
{
content: '';
position: absolute;
width: 20px;
height: 20px;
top: 5px;
left: 5px;
background-color: red;
}
Here's a LIVE DEMO
If a credit card is already added to a PayPal account then it won't let you use that card to process directly with Payments Advanced. The system expects buyers to login to PayPal and just choose that credit card as their funding source if they want to pay with it.
As for testing on the sandbox, I've always used old, expired credit cards I have laying around and they seem to work fine for me.
You could always try the ones starting on page 87 of the PayFlow documentation, too. They should work.
You make a bog standard HTTP GET Request. You get a bog standard HTTP Response with an application/json content type and a JSON document as the body. You then parse this.
Since you have tagged this 'JavaScript' (I assume you mean "from a web page in a browser"), and I assume this is a third party service, you're stuck. You can't fetch data from remote URI in JavaScript unless explicit workarounds (such as JSONP) are put in place.
Oh wait, reading the documentation you linked to - JSONP is available, but you must say 'js' not 'json' and specify a callback: format=js&callback=foo
Then you can just define the callback function:
function foo(myData) {
// do stuff with myData
}
And then load the data:
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = theUrlForTheApi;
document.body.appendChild(script);
Say your variable is myNode
, you can do myNode.value
to retrieve the value of input elements.
Firebug has a "DOM" tab which shows useful DOM attributes.
Also see the mozilla page for a reference: https://developer.mozilla.org/en-US/docs/DOM/HTMLInputElement
.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])
Python uses key,direction. You can use the above way.
So in your case you can do this
for post in db.posts.find().sort('entities.user_mentions.screen_name',pymongo.ASCENDING):
print post
You can use date function to format it by using the code below:
echo date("g:i a", strtotime("13:30:30 UTC"));
output: 1:30 pm
Modify the definition of the function check_me as::
function check_me(ev) {
Now you can access the methods and parameters of the event, in your case:
ev.preventDefault();
Then, you have to pass the parameter on the onclick in the inline call::
<button type="button" onclick="check_me(event);">Click Me!</button>
A useful link to understand this.
<!DOCTYPE html>
<html lang="en">
<head>
<script type="text/javascript">
function check_me(ev) {
ev.preventDefault();
alert("Hello World!")
}
</script>
</head>
<body>
<button type="button" onclick="check_me(event);">Click Me!</button>
</body>
</html>
Although the above is the direct answer to the question (passing an event object to an inline event), there are other ways of handling events that keep the logic separated from the presentation
addEventListener
:<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<button id='my_button' type="button">Click Me!</button>
<!-- put the javascript at the end to guarantee that the DOM is ready to use-->
<script type="text/javascript">
function check_me(ev) {
ev.preventDefault();
alert("Hello World!")
}
<!-- add the event to the button identified #my_button -->
document.getElementById("my_button").addEventListener("click", check_me);
</script>
</body>
</html>
Both of the above solutions are fine for a small project, or a hackish quick and dirty solution, but for bigger projects, it is better to keep the HTML separated from the Javascript.
Just put this two files in the same folder:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<button id='my_button' type="button">Click Me!</button>
<!-- put the javascript at the end to guarantee that the DOM is ready to use-->
<script type="text/javascript" src="example.js"></script>
</body>
</html>
function check_me(ev) {
ev.preventDefault();
alert("Hello World!")
}
document.getElementById("my_button").addEventListener("click", check_me);
This code should do it:
manifest.json
{
"name": "Alert 'hello world!' on page opening",
"version": "1.0",
"manifest_version": 2,
"content_scripts": [
{
"matches": [
"<all_urls>"
],
"js": ["content.js"]
}
]
}
content.js
alert('Hello world!')
If your computer has python, you can try this from the shell:
python -c "print len(open('test.txt').read().split('\n'))"
This uses python -c
to pass in a command, which is basically reading the file, and splitting by the "newline", to get the count of newlines, or the overall length of the file.
bash-3.2$ sed -n '$=' test.txt
519
Using the above:
bash-3.2$ python -c "print len(open('test.txt').read().split('\n'))"
519
I've got the following in my .emacs
:
(defun fontify-frame (frame)
(set-frame-parameter frame 'font "Monospace-11"))
;; Fontify current frame
(fontify-frame nil)
;; Fontify any future frames
(push 'fontify-frame after-make-frame-functions)
You can subsitute any font of your choosing for "Monospace-11"
. The set of available options is highly system-dependent. Using M-x set-default-font
and looking at the tab-completions will give you some ideas. On my system, with Emacs 23 and anti-aliasing enabled, can choose system fonts by name, e.g., Monospace
, Sans Serif
, etc.
try this code I think it is more optimal.
HeaderRow is used to repeat the header of the table for each new page automatically
BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);
PdfPTable table = new PdfPTable(10) { HorizontalAlignment = Element.ALIGN_CENTER, WidthPercentage = 100, HeaderRows = 2 };
table.SetWidths(new float[] { 2f, 6f, 6f, 3f, 5f, 8f, 5f, 5f, 5f, 5f });

Surprisingly such conversions are solutions to many problems in MySQL.
In case that you're using a directive like me this is how it works when you need the two data way binding for example after updating an attribute in any model or collection:
angular.module('yourApp').directive('setSurveyInEditionMode', setSurveyInEditionMode)
function setSurveyInEditionMode() {
return {
restrict: 'A',
link: function(scope, element, $attributes) {
element.on('click', function(event){
event.stopPropagation();
// In order to work with stopPropagation and two data way binding
// if you don't use scope.$apply in my case the model is not updated in the view when I click on the element that has my directive
scope.$apply(function () {
scope.mySurvey.inEditionMode = true;
console.log('inside the directive')
});
});
}
}
}
Now, you can easily use it in any button, link, div, etc. like so:
<button set-survey-in-edition-mode >Edit survey</button>

You may have to add the following in your web.config as well
<system.web>
<httpRuntime maxQueryStringLength="32768" maxUrlLength="65536"/>

The ssh daemon (sshd), which runs server-side, closes the connection from the server-side if the client goes silent (i.e., does not send information). To prevent connection loss, instruct the ssh client to send a sign-of-life signal to the server once in a while.
The configuration for this is in the file $HOME/.ssh/config
, create the file if it does not exist (the config file must not be world-readable, so run chmod 600 ~/.ssh/config
after creating the file). To send the signal every e.g. four minutes (240 seconds) to the remote host, put the following in that configuration file:
Host remotehost
HostName remotehost.com
ServerAliveInterval 240
To enable sending a keep-alive signal for all hosts, place the following contents in the configuration file:
Host *
ServerAliveInterval 240
There is another case where the path to the workspace may not exist, e.g., if you have imported preferences from another workspace, then some imported workspace addresses may appear in your "open workspace" dialog; then if you didn't pay attention to those addresses, you would get the exact same error once you tried to open them.

Let's say you have a tar file and you want to uncompress it after placing it in your container, remove it, you can use the COPY command to do this. Butt he various commands would be 1) Copy the tar file to the destination, 2). Uncompress it, 3) Remove the tar file. If you did this in 3 steps then there will be a new image created after each step. You can do this in one step using & but it becomes a hassle.
But you used ADD, then Docker will take care of everything for you and only one intermediate image will be created.
First you need to activate your environment .
pip install ipykernel
Next you can add your virtual environment to Jupyter by typing:
python -m ipykernel install --name = my_env
Could you add z-index style to the two sections so that the one you want appears on top?
I think the most efficient way is to preallocate and then emplace elements:
template <typename T>
std::vector<T> VectorFromSet(const std::set<T>& from)
{
std::vector<T> to;
to.reserve(from.size());
for (auto const& value : from)
to.emplace_back(value);
return to;
}
That way we will only invoke copy constructor for every element as opposed to calling default constructor first and then copy assignment operator for other solutions listed above. More clarifications below.
back_inserter may be used but it will invoke push_back() on the vector (https://en.cppreference.com/w/cpp/iterator/back_insert_iterator). emplace_back() is more efficient because it avoids creating a temporary when using push_back(). It is not a problem with trivially constructed types but will be a performance implication for non-trivially constructed types (e.g. std::string).
We need to avoid constructing a vector with the size argument which causes all elements default constructed (for nothing). Like with solution using std::copy(), for instance.
And, finally, vector::assign() method or the constructor taking the iterator range are not good options because they will invoke std::distance() (to know number of elements) on set iterators. This will cause unwanted additional iteration through the all set elements because the set is Binary Search Tree data structure and it does not implement random access iterators.
Hope that helps.
As others have said, it's a habit learned from C to avoid typos - although even in C I'd expect decent compilers at high enough warning levels to give a warning. As Chandru says, comparing against null in Java in this way would only cause problems if you were using a variable of type Boolean
(which you're not in the sample code). I'd say that's a pretty rare situation, and not one for which it's worth changing the way you write code everywhere else. (I wouldn't bother reversing the operands even in this case; if I'm thinking clearly enough to consider reversing them, I'm sure I can count the equals signs.)
What hasn't been mentioned is that many people (myself certainly included) find the if (variable == constant)
form to be more readable - it's a more natural way of expressing yourself. This is a reason not to blindly copy a convention from C. You should always question practices (as you're doing here :) before assuming that what may be useful in one environment is useful in another.
File names are case sensitive - please check your file name. it should be in same case in view folder
wc -c < filename
(short for word count, -c
prints the byte count) is a portable, POSIX solution. Only the output format might not be uniform across platforms as some spaces may be prepended (which is the case for Solaris).
Do not omit the input redirection. When the file is passed as an argument, the file name is printed after the byte count.
I was worried it wouldn't work for binary files, but it works OK on both Linux and Solaris. You can try it with wc -c < /usr/bin/wc
. Moreover, POSIX utilities are guaranteed to handle binary files, unless specified otherwise explicitly.
As I felt similarly confused with .transform
operation vs. .apply
I found a few answers shedding some light on the issue. This answer for example was very helpful.
My takeout so far is that .transform
will work (or deal) with Series
(columns) in isolation from each other. What this means is that in your last two calls:
df.groupby('A').transform(lambda x: (x['C'] - x['D']))
df.groupby('A').transform(lambda x: (x['C'] - x['D']).mean())
You asked .transform
to take values from two columns and 'it' actually does not 'see' both of them at the same time (so to speak). transform
will look at the dataframe columns one by one and return back a series (or group of series) 'made' of scalars which are repeated len(input_column)
times.
So this scalar, that should be used by .transform
to make the Series
is a result of some reduction function applied on an input Series
(and only on ONE series/column at a time).
Consider this example (on your dataframe):
zscore = lambda x: (x - x.mean()) / x.std() # Note that it does not reference anything outside of 'x' and for transform 'x' is one column.
df.groupby('A').transform(zscore)
will yield:
C D
0 0.989 0.128
1 -0.478 0.489
2 0.889 -0.589
3 -0.671 -1.150
4 0.034 -0.285
5 1.149 0.662
6 -1.404 -0.907
7 -0.509 1.653
Which is exactly the same as if you would use it on only on one column at a time:
df.groupby('A')['C'].transform(zscore)
yielding:
0 0.989
1 -0.478
2 0.889
3 -0.671
4 0.034
5 1.149
6 -1.404
7 -0.509
Note that .apply
in the last example (df.groupby('A')['C'].apply(zscore)
) would work in exactly the same way, but it would fail if you tried using it on a dataframe:
df.groupby('A').apply(zscore)
gives error:
ValueError: operands could not be broadcast together with shapes (6,) (2,)
So where else is .transform
useful? The simplest case is trying to assign results of reduction function back to original dataframe.
df['sum_C'] = df.groupby('A')['C'].transform(sum)
df.sort('A') # to clearly see the scalar ('sum') applies to the whole column of the group
yielding:
A B C D sum_C
1 bar one 1.998 0.593 3.973
3 bar three 1.287 -0.639 3.973
5 bar two 0.687 -1.027 3.973
4 foo two 0.205 1.274 4.373
2 foo two 0.128 0.924 4.373
6 foo one 2.113 -0.516 4.373
7 foo three 0.657 -1.179 4.373
0 foo one 1.270 0.201 4.373
Trying the same with .apply
would give NaNs
in sum_C
.
Because .apply
would return a reduced Series
, which it does not know how to broadcast back:
df.groupby('A')['C'].apply(sum)
giving:
A
bar 3.973
foo 4.373
There are also cases when .transform
is used to filter the data:
df[df.groupby(['B'])['D'].transform(sum) < -1]
A B C D
3 bar three 1.287 -0.639
7 foo three 0.657 -1.179
I hope this adds a bit more clarity.
I am not 100% sure what is meant by "running times of my algorithms written in python", so I thought I might try to offer a broader look at some of the potential answers.
Algorithms don't have running times; implementations can be timed, but an algorithm is an abstract approach to doing something. The most common and often the most valuable part of optimizing a program is analyzing the algorithm, usually using asymptotic analysis and computing the big O complexity in time, space, disk use and so forth.
A computer cannot really do this step for you. This requires doing the math to figure out how something works. Optimizing this side of things is the main component to having scalable performance.
You can time your specific implementation. The nicest way to do this in Python is to use timeit. The way it seems most to want to be used is to make a module with a function encapsulating what you want to call and call it from the command line with python -m timeit ...
.
Using timeit to compare multiple snippets when doing microoptimization, but often isn't the correct tool you want for comparing two different algorithms. It is common that what you want is asymptotic analysis, but it's possible you want more complicated types of analysis.
You have to know what to time. Most snippets aren't worth improving. You need to make changes where they actually count, especially when you're doing micro-optimisation and not improving the asymptotic complexity of your algorithm.
If you quadruple the speed of a function in which your code spends 1% of the time, that's not a real speedup. If you make a 20% speed increase on a function in which your program spends 50% of the time, you have a real gain.
To determine the time spent by a real Python program, use the stdlib profiling utilities. This will tell you where in an example program your code is spending its time.
on macOS (/ OS X), if someone else is having trouble with the OS apparently leaking memory:
google.maps.event.trigger($("#div_ID")[0], 'resize');
If you don't have variable map available, it should be the first element (unless you did something stupid) in the div
that contains GMAP.
Check the following example:
// First get your image
$imgPath = 'path-to-your-picture/image.jpg';
$img = base64_encode(file_get_contents($imgPath));
echo '<img width="100" height="100" src="data:image/jpg;base64,'. $img .'" />'
I had the same problem. I solve it when I convert string to factor. In your case, check the class of variable and check if they are numeric and 'train and test' should be factor.
In simple terms, inside a then
handler function:
A) When x
is a value (number, string, etc):
return x
is equivalent to return Promise.resolve(x)
throw x
is equivalent to return Promise.reject(x)
B) When x
is a Promise that is already settled (not pending anymore):
return x
is equivalent to return Promise.resolve(x)
, if the Promise was already resolved.return x
is equivalent to return Promise.reject(x)
, if the Promise was already rejected.C) When x
is a Promise that is pending:
return x
will return a pending Promise, and it will be evaluated on the subsequent then
. Read more on this topic on the Promise.prototype.then() docs.
This worked for me.
int i = 14;
int j = 26;
int k = Integer.valueOf(String.valueOf(i) + String.valueOf(j));
System.out.println(k);
It turned out as 1426
Maybe an old version of the service was not uninstalled from windows
sc delete wampapache
Reinstall the service from wamp:
Wamp Tray Icon -> Apache -> Service -> Install Service
It works for me, enjoy!
I had to do following:
2.Go to App releases -> Manage production -> Create release
3.Click continue on Google Play App Signing
4.Create upload certificate by running "keytool -genkey -v -keystore c:\path\to\cert.keystore -alias uploadKey -keyalg RSA -keysize 2048 -validity 10000"
5.Sign your apk with generated certificate (c:\path\to\cert.keystore)
6.Upload signed apk in App releases -> Manage production -> Edit release
7.By uploading apk, certificate generated in step 4 has been added to App Signing certificates and became your signing cert for all future builds.
I had the same problem but then realized the arrangement of my icon graphic within the square allowed (512 x 512 in my case) was not maximized. So I rotated the image and was able to scale it up to fill the corners better. Then I right clicked on my res
folder in my project in Android Studio, then choose New
then Image Asset
, it took me through a wizard where I got to select my image file to use. Then if you check the box that says "Trim surrounding blank space", it makes sure all edges, that are able, touch the sides of your square. These steps got it much bigger than the original.
There is nothing out there that is going to do this for you; the only way you're going to accomplish this is to iterate all the rows/columns and compare them to each other.
You need to add a 640x1136 pixels PNG image ([email protected]
) as a 4 inch default splash image of your project, and it will use extra spaces (without efforts on simple table based applications, games will require more efforts).
I've created a small UIDevice category in order to deal with all screen resolutions. You can get it here, but the code is as follows:
enum {
UIDeviceResolution_Unknown = 0,
UIDeviceResolution_iPhoneStandard = 1, // iPhone 1,3,3GS Standard Display (320x480px)
UIDeviceResolution_iPhoneRetina4 = 2, // iPhone 4,4S Retina Display 3.5" (640x960px)
UIDeviceResolution_iPhoneRetina5 = 3, // iPhone 5 Retina Display 4" (640x1136px)
UIDeviceResolution_iPadStandard = 4, // iPad 1,2,mini Standard Display (1024x768px)
UIDeviceResolution_iPadRetina = 5 // iPad 3 Retina Display (2048x1536px)
}; typedef NSUInteger UIDeviceResolution;
@interface UIDevice (Resolutions)
- (UIDeviceResolution)resolution;
NSString *NSStringFromResolution(UIDeviceResolution resolution);
@end
#import "UIDevice+Resolutions.h"
@implementation UIDevice (Resolutions)
- (UIDeviceResolution)resolution
{
UIDeviceResolution resolution = UIDeviceResolution_Unknown;
UIScreen *mainScreen = [UIScreen mainScreen];
CGFloat scale = ([mainScreen respondsToSelector:@selector(scale)] ? mainScreen.scale : 1.0f);
CGFloat pixelHeight = (CGRectGetHeight(mainScreen.bounds) * scale);
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
if (scale == 2.0f) {
if (pixelHeight == 960.0f)
resolution = UIDeviceResolution_iPhoneRetina4;
else if (pixelHeight == 1136.0f)
resolution = UIDeviceResolution_iPhoneRetina5;
} else if (scale == 1.0f && pixelHeight == 480.0f)
resolution = UIDeviceResolution_iPhoneStandard;
} else {
if (scale == 2.0f && pixelHeight == 2048.0f) {
resolution = UIDeviceResolution_iPadRetina;
} else if (scale == 1.0f && pixelHeight == 1024.0f) {
resolution = UIDeviceResolution_iPadStandard;
}
}
return resolution;
}
@end
This is how you need to use this code.
1) Add the above UIDevice+Resolutions.h & UIDevice+Resolutions.m files to your project
2) Add the line #import "UIDevice+Resolutions.h" to your ViewController.m
3) Add this code to check what versions of device you are dealing with
int valueDevice = [[UIDevice currentDevice] resolution];
NSLog(@"valueDevice: %d ...", valueDevice);
if (valueDevice == 0)
{
//unknow device - you got me!
}
else if (valueDevice == 1)
{
//standard iphone 3GS and lower
}
else if (valueDevice == 2)
{
//iphone 4 & 4S
}
else if (valueDevice == 3)
{
//iphone 5
}
else if (valueDevice == 4)
{
//ipad 2
}
else if (valueDevice == 5)
{
//ipad 3 - retina display
}
You could do this
<div style="text-align:center;">
<div style="border:1px solid #000; display:inline-block;">Div 1</div>
<div style="border:1px solid red; display:inline-block;">Div 2</div>
</div>
http://jsfiddle.net/jasongennaro/MZrym/
div
with text-align:center;
div
s a display:inline-block;
instead of a float
Best also to put that css in a stylesheet.
I've managed to bind a custom model to an element at runtime. The code is here: http://jsfiddle.net/ZiglioNZ/tzD4T/457/
The interesting bit is that I apply the data-bind attribute to an element I didn't define:
var handle = slider.slider().find(".ui-slider-handle").first();
$(handle).attr("data-bind", "tooltip: viewModel.value");
ko.applyBindings(viewModel.value, $(handle)[0]);
Given a list:
var list = new List<Child>()
{
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};
The query would look like:
var newList = list
.GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
.Select(y => new ConsolidatedChild()
{
FavoriteColor = y.Key.FavoriteColor,
Friend = y.Key.Friend,
School = y.Key.School,
Children = y.ToList()
}
);
Test code:
foreach(var item in newList)
{
Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
foreach(var child in item.Children)
{
Console.WriteLine("\t Name: {0}", child.Name);
}
}
Result:
School: School1 FavouriteColor: blue Friend: Bob
Name: John
Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
Name: Bob
There are lots of great solutions here already. However, to provide a more streamlined solution and one more in keeping with the idea of a querySelector behavior and syntax, I opted for a solution that extends Object with a couple prototype functions. Both of these functions use regular expressions for matching text, however, a string can be provided as a loose search parameter.
Simply implement the following functions:
// find all elements with inner text matching a given regular expression
// args:
// selector: string query selector to use for identifying elements on which we
// should check innerText
// regex: A regular expression for matching innerText; if a string is provided,
// a case-insensitive search is performed for any element containing the string.
Object.prototype.queryInnerTextAll = function(selector, regex) {
if (typeof(regex) === 'string') regex = new RegExp(regex, 'i');
const elements = [...this.querySelectorAll(selector)];
const rtn = elements.filter((e)=>{
return e.innerText.match(regex);
});
return rtn.length === 0 ? null : rtn
}
// find the first element with inner text matching a given regular expression
// args:
// selector: string query selector to use for identifying elements on which we
// should check innerText
// regex: A regular expression for matching innerText; if a string is provided,
// a case-insensitive search is performed for any element containing the string.
Object.prototype.queryInnerText = function(selector, text){
return this.queryInnerTextAll(selector, text)[0];
}
With these functions implemented, you can now make calls as follows:
document.queryInnerTextAll('div.link', 'go');
document.queryInnerText('div.link', 'go');
document.queryInnerTextAll('a', /^Next$/);
document.queryInnerText('a', /next/i);
e = document.querySelector('#page');
e.queryInnerText('button', /Continue/);
Here is the simplest solution:
<Grid>
<Label Content="Placeholder text" VerticalAlignment="Center" Margin="10">
<Label.Style>
<Style TargetType="Label">
<Setter Property="Foreground" Value="Transparent"/>
<Style.Triggers>
<DataTrigger Binding="{Binding Expression}" Value="">
<Setter Property="Foreground" Value="Gray"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Label.Style>
</Label>
<TextBox HorizontalAlignment="Stretch" Margin="5" Background="Transparent"
Text="{Binding Expression, UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Center" Padding="5">
</TextBox>
</Grid>
This is a textbox with transparent backgound overlaying a label. The label's gray text is turned transparent by a data trigger that fires whenever the bound text is something other than empty string.
I didnt see this question answered:
How should I setup a default Area when the application starts?
So, here is how you can set up a default Area:
var route = routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
).DataTokens = new RouteValueDictionary(new { area = "MyArea" });
This error would suggest that User::where('email', '=', $userEmail)->first()
is returning null, rather than a problem with updating your model.
Check that you actually have a User before attempting to change properties on it, or use the firstOrFail()
method.
$UpdateDetails = User::where('email', $userEmail)->first();
if (is_null($UpdateDetails)) {
return false;
}
or using the firstOrFail()
method, theres no need to check if the user is null because this throws an exception (ModelNotFoundException
) when a model is not found, which you can catch using App::error()
http://laravel.com/docs/4.2/errors#handling-errors
$UpdateDetails = User::where('email', $userEmail)->firstOrFail();
