For those that are on Mac OSX, perhaps the easiest way to work around this is to use ditto (only on the mac, AFAIK, though). It will create the directory structure that is missing in the destination.
For instance, I did this
ditto 6.3.2/6.3.2/macosx/bin/mybinary ~/work/binaries/macosx/6.3.2/
where ~/work
did not contain the binaries directory before I ran the command.
I thought rsync should work similarly, but it seems it only works for one level of missing directories. That is,
rsync 6.3.3/6.3.3/macosx/bin/mybinary ~/work/binaries/macosx/6.3.3/
worked, because ~/work/binaries/macosx existed but not ~/work/binaries/macosx/6.3.2/
The answer above is now obsolete with Unity 5 or newer. Use this instead!
GetComponent<Rigidbody2D>().AddForce(new Vector2(0,10), ForceMode2D.Impulse);
I also want to add that this leaves the jump height super private and only editable in the script, so this is what I did...
public float playerSpeed; //allows us to be able to change speed in Unity
public Vector2 jumpHeight;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update ()
{
transform.Translate(playerSpeed * Time.deltaTime, 0f, 0f); //makes player run
if (Input.GetMouseButtonDown(0) || Input.GetKeyDown(KeyCode.Space)) //makes player jump
{
GetComponent<Rigidbody2D>().AddForce(jumpHeight, ForceMode2D.Impulse);
This makes it to where you can edit the jump height in Unity itself without having to go back to the script.
Side note - I wanted to comment on the answer above, but I can't because I'm new here. :)
Since not all datetime.datetime
instances have a microsecond component (i.e. when it is zero), you can partition the string on a "." and take only the first item, which will always work:
unicode(datetime.datetime.now()).partition('.')[0]

If you want to do this, you need to save it in a variable first. So you don't need to use id to query this element every time.
var el = $("#page_navigation1");
$("#add").click(function(){
el.attr("id","page_navigation1");
});
$("#remove").click(function(){
el.removeAttr("id");
});
If you are in the fragment itself, you need to call this. Your fragment needs to be the fragment that is being called. Enter code:
getFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();
or if you are using supportLib
, then you need to call:
getSupportFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();
Port 465: IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.
However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer ISP articles that suggest port 465 as the recommended setup. Hopefully this ends soon! It is not RFC compliant.
Port 587: This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.
Everyone should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.
Port 25: This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.
In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn't use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.
Make sure your escaping the HTML characters
E.g.
// Always check an input variable is set before you use it
if (isset($_POST['contact_list'])) {
// Escape any html characters
echo htmlentities($_POST['contact_list']);
}
This would occur because of the angle brackets and the browser thinking they are tags.
Building on Chaz's answer, in .NET 5 there is a breaking change, so two modifications are required in the project file, i.e. changing OutputType
and adding DisableWinExeOutputInference
. Example:
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net5.0-windows10.0.17763.0</TargetFramework>
<UseWindowsForms>true</UseWindowsForms>
<DisableWinExeOutputInference>true</DisableWinExeOutputInference>
<Platforms>AnyCPU;x64;x86</Platforms>
</PropertyGroup>

I use
set "VAR_NAME=<String With Spaces>"
when updating path:
set "PATH=%UTIL_DIR%;%PATH%"
This works in latest Chrome, FireFox and Edge, but not IE11:
document.evaluate('//option[text()="Yahoo"]', document).iterateNext().selected = 'selected';
And if you want to ignore spaces around the title:
document.evaluate('//option[normalize-space(text())="Yahoo"]', document).iterateNext().selected = 'selected'
As an alternative answer, there's a command line to invoke directly the Control Panel, which is javaws -viewer

System: Windows 7, Android Studio.
This error occurred when I ran adb devices
from Windows Commandline.
The root cause was that the adb I was running from commandline was not the same adb running from Android Studio.
Solution:
First kill all running adb processes on the machine.
taskkill /F /IM adb.exe
Run your app from Android Studio.
Locate the exact File Location of adb.exe either from Windows Task Manager, OR by running the command below
wmic process where "name='adb.exe'" get ProcessID, ExecutablePath
On Windows Command prompt, run where adb
to locate the adb that runs from command prompt. This path would be different from the one in Step 3 above.
Edit Windows system variable PATH. Delete the base path found in Step 4 from it.
After you have edited PATH, you can see the current contents of this variable by typing below command in a NEW command prompt (don't use old prompt.)
echo %PATH%
Now, run adb from command prompt. It should NOT show any "server out of date error"!
Why myList[1] is considered a 'str' object?
Because it is a string. What else is 'from form'
, if not a string? (Actually, strings are sequences too, i.e. they can be indexed, sliced, iterated, etc. as well - but that's part of the str
class and doesn't make it a list or something).
mList[1]
returns the first item in the list'from form'
If you mean that myList
is 'from form'
, no it's not!!! The second (indexing starts at 0) element is 'from form'
. That's a BIG difference. It's the difference between a house and a person.
Also, myList
doesn't have to be a list
from your short code sample - it could be anything that accepts 1
as index - a dict with 1 as index, a list, a tuple, most other sequences, etc. But that's irrelevant.
but I cannot append to item 1 in the list
myList
Of course not, because it's a string and you can't append to string. String are immutable. You can concatenate (as in, "there's a new object that consists of these two") strings. But you cannot append
(as in, "this specific object now has this at the end") to them.
There is a constant that you can check against:
someBigDecimal.compareTo(BigDecimal.ZERO) == 0
I agree with Charles Duffy that a proper XML parser is the right way to go.
But as to what's wrong with your sed
command (or did you do it on purpose?).
$data
was not quoted, so $data
is subject to shell's word splitting, filename expansion among other things. One of the consequences being that the spacing in the XML snippet is not preserved.So given your specific XML structure, this modified sed
command should work
title=$(sed -ne '/title/{s/.*<title>\(.*\)<\/title>.*/\1/p;q;}' <<< "$data")
Basically for the line that contains title
, extract the text between the tags, then quit (so you don't extract the 2nd <title>
)
Use the code
x = seq(0,100,5) #this means (starting number, ending number, interval)
the output will be
[1] 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75
[17] 80 85 90 95 100

.then(function scb(response) {_x000D_
var dataResponse = response.data;_x000D_
//if response.data for example is : localhost/export/data.csv_x000D_
_x000D_
//the following will download the file without changing the current page location_x000D_
window.location = 'http://'+ response.data_x000D_
}, function(response) {_x000D_
showWarningNotification($filter('translate')("global.errorGetDataServer"));_x000D_

java.util.Date date = ...

The following codes can be used:
@app.route('/api/add_message/<uuid>', methods=['GET', 'POST'])
def add_message(uuid):
content = request.json['text']
print content
return uuid
Here is a screenshot of me getting the json data:
You can see that what is returned is a dictionary type of data.
The solutions so far are all quite complicated. The idiomatic solution should doubtless be:
String.Join(",", x.Cast(Of String)().ToArray())
There's no need for fancy acrobatics in new framework versions. Supposing a not-so-modern version, the following would be easiest:
Console.WriteLine(String.Join(",", CType(x.ToArray(GetType(String)), String())))
mspmsp's second solution is a nice approach as well but it's not working because it misses the AddressOf
keyword. Also, Convert.ToString
is rather inefficient (lots of unnecessary internal evaluations) and the Convert
class is generally not very cleanly designed. I tend to avoid it, especially since it's completely redundant.
function Person(firstname, lastname) {
this.firstname = firstname;
this.lastname = lastname;
this.getfullname = function () {
return `${this.firstname} ${this.lastname}`;
};
let that = this;
this.sayHi = function() {
console.log(`i am this , ${this.firstname}`);
console.log(`i am that , ${that.firstname}`);
};
}
let thisss = new Person('thatbetty', 'thatzhao');
let thatt = {firstname: 'thisbetty', lastname: 'thiszhao'};
thisss.sayHi.call(thatt);
The answer to this question has changed over the years. The current answer is here at the top, followed by the various answers over the years in chronological order:
You can use fs.existsSync()
:
const fs = require("fs"); // Or `import fs from "fs";` with ESM
if (fs.existsSync(path)) {
// Do something
}
It was deprecated for several years, but no longer is. From the docs:
Note that
fs.exists()
is deprecated, butfs.existsSync()
is not. (The callback parameter tofs.exists()
accepts parameters that are inconsistent with other Node.js callbacks.fs.existsSync()
does not use a callback.)
You've specifically asked for a synchronous check, but if you can use an asynchronous check instead (usually best with I/O), use fs.promises.access
if you're using async
functions or fs.access
(since exists
is deprecated) if not:
In an async
function:
try {
await fs.promises.access("somefile");
// The check succeeded
} catch (error) {
// The check failed
}
Or with a callback:
fs.access("somefile", error => {
if (!error) {
// The check succeeded
} else {
// The check failed
}
});
Here are the historical answers in chronological order:
stat
/statSync
or lstat
/lstatSync
)exists
/existsSync
)exists
/existsSync
, so we're probably back to stat
/statSync
or lstat
/lstatSync
)fs.access(path, fs.F_OK, function(){})
/ fs.accessSync(path, fs.F_OK)
, but note that if the file/directory doesn't exist, it's an error; docs for fs.stat
recommend using fs.access
if you need to check for existence without opening)fs.exists()
is still deprecated but fs.existsSync()
is no longer deprecated. So you can safely use it now.You can use statSync
or lstatSync
(docs link), which give you an fs.Stats
object. In general, if a synchronous version of a function is available, it will have the same name as the async version with Sync
at the end. So statSync
is the synchronous version of stat
; lstatSync
is the synchronous version of lstat
, etc.
lstatSync
tells you both whether something exists, and if so, whether it's a file or a directory (or in some file systems, a symbolic link, block device, character device, etc.), e.g. if you need to know if it exists and is a directory:
var fs = require('fs');
try {
// Query the entry
stats = fs.lstatSync('/the/path');
// Is it a directory?
if (stats.isDirectory()) {
// Yes it is
}
}
catch (e) {
// ...
}
...and similarly, if it's a file, there's isFile
; if it's a block device, there's isBlockDevice
, etc., etc. Note the try/catch
; it throws an error if the entry doesn't exist at all.
If you don't care what the entry is and only want to know whether it exists, you can use path.existsSync
(or with latest, fs.existsSync
) as noted by user618408:
var path = require('path');
if (path.existsSync("/the/path")) { // or fs.existsSync
// ...
}
It doesn't require a try/catch
but gives you no information about what the thing is, just that it's there. path.existsSync
was deprecated long ago.
Side note: You've expressly asked how to check synchronously, so I've used the xyzSync
versions of the functions above. But wherever possible, with I/O, it really is best to avoid synchronous calls. Calls into the I/O subsystem take significant time from a CPU's point of view. Note how easy it is to call lstat
rather than lstatSync
:
// Is it a directory?
lstat('/the/path', function(err, stats) {
if (!err && stats.isDirectory()) {
// Yes it is
}
});
But if you need the synchronous version, it's there.
The below answer from a couple of years ago is now a bit out of date. The current way is to use fs.existsSync
to do a synchronous check for file/directory existence (or of course fs.exists
for an asynchronous check), rather than the path
versions below.
Example:
var fs = require('fs');
if (fs.existsSync(path)) {
// Do something
}
// Or
fs.exists(path, function(exists) {
if (exists) {
// Do something
}
});
And here we are in 2015 and the Node docs now say that fs.existsSync
(and fs.exists
) "will be deprecated". (Because the Node folks think it's dumb to check whether something exists before opening it, which it is; but that's not the only reason for checking whether something exists!)
So we're probably back to the various stat
methods... Until/unless this changes yet again, of course.
Don't know how long it's been there, but there's also fs.access(path, fs.F_OK, ...)
/ fs.accessSync(path, fs.F_OK)
. And at least as of October 2016, the fs.stat
documentation recommends using fs.access
to do existence checks ("To check if a file exists without manipulating it afterwards, fs.access()
is recommended."). But note that the access not being available is considered an error, so this would probably be best if you're expecting the file to be accessible:
var fs = require('fs');
try {
fs.accessSync(path, fs.F_OK);
// Do something
} catch (e) {
// It isn't accessible
}
// Or
fs.access(path, fs.F_OK, function(err) {
if (!err) {
// Do something
} else {
// It isn't accessible
}
});
You can use fs.existsSync()
:
if (fs.existsSync(path)) {
// Do something
}
It was deprecated for several years, but no longer is. From the docs:
Note that
fs.exists()
is deprecated, butfs.existsSync()
is not. (The callback parameter tofs.exists()
accepts parameters that are inconsistent with other Node.js callbacks.fs.existsSync()
does not use a callback.)

Its also possible to use dynamic SQL and execute it with the exec command:
declare @sql nvarchar(200), @count int
set @count = 10
set @sql = N'select top ' + cast(@count as nvarchar(4)) + ' * from table'
exec (@sql)
//An example of implementation :
// we set the score of one player to a value
[Game getCurrent].scorePlayer1 = [NSNumber numberWithInteger:1];
// We copy the value in a NSNumber
NSNumber *aNumber = [Game getCurrent].scorePlayer1;
// Conversion of the NSNumber aNumber to a String with stringValue
NSString *StringScorePlayer1 = [aNumber stringValue];
If you want to be able to have a SELECT without problems of the parent id having to be lower than child id, a function could be used. It supports also multiple children (as a tree should do) and the tree can have multiple heads. It also ensure to break if a loop exists in the data.
I wanted to use dynamic SQL to be able to pass the table/columns names, but functions in MySQL don't support this.

If you don't have FTP access or too lazy to edit files,
You can use Increase Maximum Upload File Size plugin to increase the maximum upload file size.
You can simply return
if you want to skip the current iteration.
Since you're in a function, if you return
before doing anything else, then you have effectively skipped execution of the code below the return
statement.
inelegant (but effective) way: use percentages
#horizontal-style {
width: 100%;
}
li {
width: 20%;
}
This only works with the 5 <li>
example. For more or less, modify your percentage accordingly. If you have other <li>
s on your page, you can always assign these particular ones a class of "menu-li" so that only they are affected.

I know this is 3 years too late, but Matt's (accepted) answer is incomplete and will eventually get you into trouble. The key here is that, if you choose to use multipart/form-data
, the boundary must not appear in the file data that the server eventually receives.
This is not a problem for application/x-www-form-urlencoded
, because there is no boundary. x-www-form-urlencoded
can also always handle binary data, by the simple expedient of turning one arbitrary byte into three 7BIT
bytes. Inefficient, but it works (and note that the comment about not being able to send filenames as well as binary data is incorrect; you just send it as another key/value pair).
The problem with multipart/form-data
is that the boundary separator must not be present in the file data (see RFC 2388; section 5.2 also includes a rather lame excuse for not having a proper aggregate MIME type that avoids this problem).
So, at first sight, multipart/form-data
is of no value whatsoever in any file upload, binary or otherwise. If you don't choose your boundary correctly, then you will eventually have a problem, whether you're sending plain text or raw binary - the server will find a boundary in the wrong place, and your file will be truncated, or the POST will fail.
The key is to choose an encoding and a boundary such that your selected boundary characters cannot appear in the encoded output. One simple solution is to use base64
(do not use raw binary). In base64 3 arbitrary bytes are encoded into four 7-bit characters, where the output character set is [A-Za-z0-9+/=]
(i.e. alphanumerics, '+', '/' or '='). =
is a special case, and may only appear at the end of the encoded output, as a single =
or a double ==
. Now, choose your boundary as a 7-bit ASCII string which cannot appear in base64
output. Many choices you see on the net fail this test - the MDN forms docs, for example, use "blob" as a boundary when sending binary data - not good. However, something like "!blob!" will never appear in base64
output.
You probably want to use a regex like the one described here to check the format. When the form's submitted, run the following test on each field:
var userinput = $(this).val();
var pattern = /^\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b$/i
if(!pattern.test(userinput))
{
alert('not a valid e-mail address');
}?
What is the difference between them?
Image: the generic Linux kernel binary image file.
zImage: a compressed version of the Linux kernel image that is self-extracting.
uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.
Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:
Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.
(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)
Which type of kernel image do I have to use?
You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.
ADDENDUM
I know that u-boot needs a kernel in uImage format.
That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.
If your method is void and you want to check for an exception, you could use expected

https://weblogs.java.net/blog/johnsmart/archive/2009/09/27/testing-exceptions-junit-47
nameContent
only exists within the first()
function, as you defined it within the first()
function.
To make its scope broader, define it outside of the functions:
var nameContent;
function first(){
nameContent=document.getElementById('full_name').value;
}
function second() {
first();
y=nameContent; alert(y);
}
second();
A slightly better approach would be to return
the value, as global variables get messy very quickly:
function getFullName() {
return document.getElementById('full_name').value;
}
function doStuff() {
var name = getFullName();
alert(name);

all the major javascript libraries like jscript, prototype, YUI have support for loading script files. For example, in YUI, after loading the core you can do the following to load the calendar control
var loader = new YAHOO.util.YUILoader({
require: ['calendar'], // what components?
base: '../../build/',//where do they live?
//filter: "DEBUG", //use debug versions (or apply some
//some other filter?
//loadOptional: true, //load all optional dependencies?
//onSuccess is the function that YUI Loader
//should call when all components are successfully loaded.
onSuccess: function() {
//Once the YUI Calendar Control and dependencies are on
//the page, we'll verify that our target container is
//available in the DOM and then instantiate a default
//calendar into it:
YAHOO.util.Event.onAvailable("calendar_container", function() {
var myCal = new YAHOO.widget.Calendar("mycal_id", "calendar_container");
myCal.render();
})
},
// should a failure occur, the onFailure function will be executed
onFailure: function(o) {
alert("error: " + YAHOO.lang.dump(o));
}
});
// Calculate the dependency and insert the required scripts and css resources
// into the document
loader.insert();
You might consider Joda Time or Java 8, which has a type called LocalTime
specifically for a time of day without a date component.
Example code in Joda-Time 2.7/Java 8.
LocalTime t = LocalTime.parse( "17:40" ) ;
This answer comes a little late, but it completes the response.
In order to avoid a field from an entity to be persisted in DB one can use one of the two mechanisms:
@Transient - the JPA annotation marking a field as not persistable
transient keyword in java. Beware - using this keyword, will prevent the field to be used with any serialization mechanism from java. So, if the field must be serialized you'd better use just the @Transient annotation.
I don't think there's anything built in that you can use however I did find lots of examples of people rolling their own.
this.requestWindowFeature(getWindow().FEATURE_NO_TITLE);
You would usually do something like this:
while ( resultSet.next() ) {
// Read the next item
resultSet.getString("columnName");
}
If you want to report an empty set, add a variable counting the items read. If you only need to read a single item, then your code is adequate.
If you’re concerned about your code breaking, you should commit the composer.lock
to your version control system to ensure all your project collaborators are using the same version of the code. Without a lock file, you will get new third-party code being pulled down each time.
The exception is when you use a meta apps, libraries where the dependencies should be updated on install (like the Zend Framework 2 Skeleton App). So the aim is to grab the latest dependencies each time when you want to start developing.

I had it when I did so :
function foo() (...) export default foo
correctly:
export default () =>(...);
or
const foo = ...
export default foo
Inspired by Nelson's and Chris' comments, I've found a way to workaround the same origin policy with a div
and an iframe
:
HTML:
<div id='div_iframe'><iframe id='frame' src='...'></iframe></div>
CSS:
#div_iframe {
border-style: inset;
border-color: grey;
overflow: scroll;
height: 500px;
width: 90%
}
#frame {
width: 100%;
height: 1000%; /* 10x the div height to embrace the whole page */
}
Now suppose I want to skip the first 438 (vertical) pixels of the iframe page, by scrolling to that position.
JS solution:
document.getElementById('div_iframe').scrollTop = 438
JQuery solution:
$('#div_iframe').scrollTop(438)
CSS solution:
#frame { margin-top: -438px }
(Each solution alone is enough, and the effect of the CSS one is a little different since you can't scroll up to see the top of the iframed page.)
You could give the target parent an id or class (e.g. myParent) and reference is with $('#element').parents(".myParent")
However, will it automatically remove these committed files from the repository?
No.
The 'best' recipe to do this is using git filter-branch
as written about here:
The man page for git-filter-branch contains comprehensive examples.
Note You'll be re-writing history. If you had published any revisions containing the accidentally added files, this could create trouble for users of those public branches. Inform them, or perhaps think about how badly you need to remove the files.
Note In the presence of tags, always use the --tag-name-filter cat
option to git filter-branch
. It never hurts and will save you the head-ache when you realize later taht you needed it
You're accessing the latitude and longitude incorrectly.
Try
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder = new google.maps.Geocoder();
var address = "new york";
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
alert(latitude);
}
});
</script>
In order to insert the text from activity2 to activity1, you first need to create a visit function in activity2.
public void visitactivity1()
{
Intent i = new Intent(this, activity1.class);
i.putExtra("key", message);
startActivity(i);
}
After creating this function, you need to call it from your onCreate() function of activity2:
visitactivity1();
Next, go on to the activity1 Java file. In its onCreate() function, create a Bundle object, fetch the earlier message via its key through this object, and store it in a String.
Bundle b = getIntent().getExtras();
String message = b.getString("key", ""); // the blank String in the second parameter is the default value of this variable. In case the value from previous activity fails to be obtained, the app won't crash: instead, it'll go with the default value of an empty string
Now put this element in a TextView or EditText, or whichever layout element you prefer using the setText() function.
All of these answers appear to be incomplete and/or kludges. Looking at the RestTemplate interface, it sure looks like it is intended to have a ClientHttpRequestFactory
injected into it, and then that requestFactory will be used to create the request, including any customizations of headers, body, and request params.
You either need a universal ClientHttpRequestFactory
to inject into a single shared RestTemplate
or else you need to get a new template instance via new RestTemplate(myHttpRequestFactory)
.
Unfortunately, it looks somewhat non-trivial to create such a factory, even when you just want to set a single Authorization header, which is pretty frustrating considering what a common requirement that likely is, but at least it allows easy use if, for example, your Authorization header can be created from data contained in a Spring-Security Authorization
object, then you can create a factory that sets the outgoing AuthorizationHeader on every request by doing SecurityContextHolder.getContext().getAuthorization()
and then populating the header, with null checks as appropriate. Now all outbound rest calls made with that RestTemplate will have the correct Authorization header.
Without more emphasis placed on the HttpClientFactory mechanism, providing simple-to-overload base classes for common cases like adding a single header to requests, most of the nice convenience methods of RestTemplate
end up being a waste of time, since they can only rarely be used.
I'd like to see something simple like this made available
@Configuration
public class MyConfig {
@Bean
public RestTemplate getRestTemplate() {
return new RestTemplate(new AbstractHeaderRewritingHttpClientFactory() {
@Override
public HttpHeaders modifyHeaders(HttpHeaders headers) {
headers.addHeader("Authorization", computeAuthString());
return headers;
}
public String computeAuthString() {
// do something better than this, but you get the idea
return SecurityContextHolder.getContext().getAuthorization().getCredential();
}
});
}
}
At the moment, the interface of the available ClientHttpRequestFactory's are harder to interact with than that. Even better would be an abstract wrapper for existing factory implementations which makes them look like a simpler object like AbstractHeaderRewritingRequestFactory for the purposes of replacing just that one piece of functionality. Right now, they are very general purpose such that even writing those wrappers is a complex piece of research.
What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut
or via an instance e.g. shape.lolwut
but be careful while setting it as it will set an instance level attribute not class attribute
class Shape(object):
lolwut = 1
shape = Shape()
print Shape.lolwut, # 1
print shape.lolwut, # 1
# setting shape.lolwut would not change class attribute lolwut
# but will create it in the instance
shape.lolwut = 2
print Shape.lolwut, # 1
print shape.lolwut, # 2
# to change class attribute access it via class
Shape.lolwut = 3
print Shape.lolwut, # 3
print shape.lolwut # 2
output:
1 1 1 2 3 2
Somebody may expect output to be 1 1 2 2 3 3
but it would be incorrect
In object oriented programming, a type includes a collection of member fields. These fields may be stored either by value or by reference (i.e., a pointer to a value).
In a shallow copy, a new instance of the type is created and the values are copied into the new instance. The reference pointers are also copied just like the values. Therefore, the references are pointing to the original objects. Any changes to the members that are stored by reference appear in both the original and the copy, since no copy was made of the referenced object.
In a deep copy, the fields that are stored by value are copied as before, but the pointers to objects stored by reference are not copied. Instead, a deep copy is made of the referenced object, and a pointer to the new object is stored. Any changes that are made to those referenced objects will not affect other copies of the object.
Yes. Try:
class USBDevice : GenericDevice, IOurDevice
Note: The base class should come before the list of interface names.
Of course, you'll still need to implement all the members that the interfaces define. However, if the base class contains a member that matches an interface member, the base class member can work as the implementation of the interface member and you are not required to manually implement it again.
We can also use ReentrantLock to achieve the synchronization for static variables.
public class Test {
private static int count = 0;
private static final ReentrantLock reentrantLock = new ReentrantLock();
public void foo() {
reentrantLock.lock();
count = count + 1;
reentrantLock.unlock();
}
}
file = open("path/of/file/(optional)/filename.txt", "w") #a=append,w=write,r=read
any_string = "Hello\nWorld"
file.write(any_string)
file.close()
Some good answers here. Especially the one by @torek. I thought I'd add this work-around with a little explanation for those in a rush.
To summarize, what happens is that when you move a tag locally, it changes the tag from a non-Null commit value to a different value. However, because git (as a default behavior) doesn't allow changing non-Null remote tags, you can't push the change.
The work-around is to delete the tag (and tick remove all remotes). Then create the same tag and push.

As SeanC points out, this must be a 1-D array.
The following example call demonstrates that the IsInArray()
function cannot be called only for 1-dim arrays,
but also for "flat" 2-dim arrays:
Sub TestIsInArray()
Const SearchItem As String = "ghi"
Debug.Print "SearchItem = '" & SearchItem & "'"
'----
'a) Test 1-dim array
Dim Arr As Variant
Arr = Split("abc,def,ghi,jkl", ",")
Debug.Print "a) 1-dim array " & vbNewLine & " " & Join(Arr, "|") & " ~~> " & IsInArray(SearchItem, Arr)
'----
'//quick tool to create a 2-dim 1-based array
Dim v As Variant, vals As Variant
v = Array(Array("abc", "def", "dummy", "jkl", 5), _
Array("mno", "pqr", "stu", "ghi", "vwx"))
v = Application.Index(v, 0, 0) ' create 2-dim array (2 rows, 5 cols)
'b) Test "flat" 2-dim arrays
Debug.Print "b) ""flat"" 2-dim arrays "
Dim i As Long
For i = LBound(v) To UBound(v)
'slice "flat" 2-dim arrays of one row each
vals = Application.Index(v, i, 0)
'check for findings
Debug.Print Format(i, " 0"), Join(vals, "|") & " ~~> " & IsInArray(SearchItem, vals)
Next i
End Sub
Function IsInArray(stringToBeFound As String, Arr As Variant) As Boolean

Update: since the time I answered this there has been a lot of work on this look at Apache Arrow for a better read and write of parquet. Also: http://wesmckinney.com/blog/python-parquet-multithreading/
There is a python parquet reader that works relatively well: https://github.com/jcrobak/parquet-python
It will create python objects and then you will have to move them to a Pandas DataFrame so the process will be slower than pd.read_csv
for example.
You can also use numpy.subtract
It has the advantage over the difference operator, -
, that you do not have to transform the sequences (list or tuples) into a numpy arrays — you save the two commands:
array1 = np.array([1.1, 2.2, 3.3])
array2 = np.array([1, 2, 3])
Example: (Python 3.5)
import numpy as np
result = np.subtract([1.1, 2.2, 3.3], [1, 2, 3])
print ('the difference =', result)
which gives you
the difference = [ 0.1 0.2 0.3]
Remember, however, that if you try to subtract sequences (lists or tuples) with the -
operator you will get an error. In this case, you need the above commands to transform the sequences in numpy arrays
Wrong Code:
print([1.1, 2.2, 3.3] - [1, 2, 3])
'SELECT * FROM Employ where number = ' + parseInt(val, 10) + ';'
For example, if val
is "10"
then this will end up building the string:
"SELECT * FROM Employ where number = 10;"
Sending a docker image to a remote server can be done in 3 simple steps:
docker save -o <path for created tar file> <image name>
Locally, use scp to transfer .tar to remote
On remote server, load image into docker:
docker load -i <path to docker image tar file>

Try setting the height of the html element to 100% as well.
html,
body {
height: 100%;
}
Body looks to its parent (HTML) for how to scale the dynamic property, so the HTML element needs to have its height set as well.
However the content of body will probably need to change dynamically. Setting min-height to 100% will accomplish this goal.
html {
height: 100%;
}
body {
min-height: 100%;
}
You can set this at boot by adding the "elevator" parameter to the kernel cmdline (such as in grub.cfg)
Example:
elevator=deadline
This will make "deadline" the default I/O scheduler for all block devices.
If you'd like to query or change the scheduler after the system has booted, or would like to use a different scheduler for a specific block device, I recommend installing and use the tool ioschedset to make this easy.
https://github.com/kata198/ioschedset
If you're on Archlinux it's available in aur:
https://aur.archlinux.org/packages/ioschedset
Some example usage:
# Get i/o scheduler for all block devices
[username@hostname ~]$ io-get-sched
sda: bfq
sr0: bfq
# Query available I/O schedulers
[username@hostname ~]$ io-set-sched --list
mq-deadline kyber bfq none
# Set sda to use "kyber"
[username@hostname ~]$ io-set-sched kyber /dev/sda
Must be root to set IO Scheduler. Rerunning under sudo...
[sudo] password for username:
+ Successfully set sda to 'kyber'!
# Get i/o scheduler for all block devices to assert change
[username@hostname ~]$ io-get-sched
sda: kyber
sr0: bfq
# Set all block devices to use 'deadline' i/o scheduler
[username@hostname ~]$ io-set-sched deadline
Must be root to set IO Scheduler. Rerunning under sudo...
+ Successfully set sda to 'deadline'!
+ Successfully set sr0 to 'deadline'!
# Get the current block scheduler just for sda
[username@hostname ~]$ io-get-sched sda
sda: mq-deadline
Usage should be self-explanatory. The tools are standalone and only require bash.
Hope this helps!
EDIT: Disclaimer, these are scripts I wrote.
A more Git based approach would be to make the changes to your local copy using cd
or copy and pasting and then pushing these changes from local to remote repository.
If you try checking status of your local repo, it may show "untracked changes" which are actually the relocated files. To push these changes forcefully, you need to stage these files/directories by using
$ git add -A
#And commiting them
$ git commit -m "Relocating image demo files"
#And finally, push
$ git push -u local_repo -f HEAD:master
Hope it helps.
For anything with requests to URLs you might want to check out requests. For JSON in particular:

One simple rewrite of the command in the question is:
grep "word1" logs | grep "word2"
The first grep
finds lines with 'word1' from the file 'logs' and then feeds those into the second grep
which looks for lines containing 'word2'.
However, it isn't necessary to use two commands like that. You could use extended grep
(grep -E
or egrep
):
grep -E 'word1.*word2|word2.*word1' logs
If you know that 'word1' will precede 'word2' on the line, you don't even need the alternatives and regular grep
would do:
grep 'word1.*word2' logs
The 'one command' variants have the advantage that there is only one process running, and so the lines containing 'word1' do not have to be passed via a pipe to the second process. How much this matters depends on how big the data file is and how many lines match 'word1'. If the file is small, performance isn't likely to be an issue and running two commands is fine. If the file is big but only a few lines contain 'word1', there isn't going to be much data passed on the pipe and using two command is fine. However, if the file is huge and 'word1' occurs frequently, then you may be passing significant data down the pipe where a single command avoids that overhead. Against that, the regex is more complex; you might need to benchmark it to find out what's best — but only if performance really matters. If you run two commands, you should aim to select the less frequently occurring word in the first grep
to minimize the amount of data processed by the second.
The initial script is:
grep -c "word1" | grep -r "word2" logs
This is an odd command sequence. The first grep
is going to count the number of occurrences of 'word1' on its standard input, and print that number on its standard output. Until you indicate EOF (e.g. by typing Control-D), it will sit there, waiting for you to type something. The second grep
does a recursive search for 'word2' in the files underneath directory logs
(or, if it is a file, in the file logs
). Or, in my case, it will fail since there's neither a file nor a directory called logs
where I'm running the pipeline. Note that the second grep
doesn't read its standard input at all, so the pipe is superfluous.
With Bash, the parent shell waits until all the processes in the pipeline have exited, so it sits around waiting for the grep -c
to finish, which it won't do until you indicate EOF. Hence, your code seems to get stuck. With Heirloom Shell, the second grep
completes and exits, and the shell prompts again. Now you have two processes running, the first grep
and the shell, and they are both trying to read from the keyboard, and it is not determinate which one gets any given line of input (or any given EOF indication).
Note that even if you typed data as input to the first grep
, you would only get any lines that contain 'word2' shown on the output.
Footnote:
At one time, the answer used:
grep -E 'word1.*word2|word2.*word1' "$@"
grep 'word1.*word2' "$@"
This triggered the comments below.
I think that this is the correct way:
class Game extends Eloquent {
// many more stuff here
// relation without any constraints ...works fine
public function videos() {
return $this->hasMany('Video');
}
// results in a "problem", se examples below
public function available_videos() {
return $this->videos()->where('available','=', 1);
}
}
And then you'll have to
$game = Game::find(1);
var_dump( $game->available_videos()->get() );
This seems like an old thread, but I'll add my experience here. I tried to install a cert as well and got that error. I then opened the cer file with a txt editor, and noticed that there is an extra space (character) at the end of each line. Removing those lines allowed me to import the cert.
Hope this is worth something to someone else.

I think StyleCop is the reason of the this issue. So,
The pip's proxy parameter is, according to pip --help
, in the form scheme://[user:passwd@]proxy.server:port
You should use the following:
pip install --proxy http://user:password@proxyserver:port TwitterApi
Also, the HTTP_PROXY
env var should be respected.
Note that in earlier versions (couldn't track down the change in the code, sorry, but the doc was updated here), you had to leave the scheme://
part out for it to work, i.e. pip install --proxy user:password@proxyserver:port

Use:

/// Cut End. "12".SubstringFromEnd(1) -> "1"
/// </summary>
public static string SubstringFromEnd(this string value, int startindex)
{

return value.Substring(0, value.Length - startindex);
}
}
I prefer an extension method here for two reasons:

put this inside your Manifest like this in No fullscreen Mode
android:windowSoftInputMode="stateVisible|adjustPan"
in your manifest
<activity
android:windowSoftInputMode="stateVisible|adjustPan"
android:name="com.example.patronusgps.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I put this:

|| ([self respondsToSelector:@selector(length)]
&& [(NSData *)self length] == 0)
|| ([self respondsToSelector:@selector(count)]
&& [(NSArray *)self count] == 0));
};
@end
The problem is that if self is nil, this function is never called. It'll return false, which is desired.
If you are seeing an error something like

I would recommend using Wireshark, which has a "Follow TCP Stream" option that makes it very easy to see the full requests and responses for a particular TCP connection. If you would prefer to use the command line, you can try tcpflow, a tool dedicated to capturing and reconstructing the contents of TCP streams.
Other options would be using an HTTP debugging proxy, like Charles or Fiddler as EricLaw suggests. These have the advantage of having specific support for HTTP to make it easier to deal with various sorts of encodings, and other features like saving requests to replay them or editing requests.
You could also use a tool like Firebug (Firefox), Web Inspector (Safari, Chrome, and other WebKit-based browsers), or Opera Dragonfly, all of which provide some ability to view the request and response headers and bodies (though most of them don't allow you to see the exact byte stream, but instead how the browsers parsed the requests).
And finally, you can always construct requests by hand, using something like telnet, netcat, or socat to connect to port 80 and type the request in manually, or a tool like htty to help easily construct a request and inspect the response.
You have written like
@Html.RadioButtonFor(model => model.gender, "Male", new { @checked = true }) and
@Html.RadioButtonFor(model => model.gender, "Female", new { @checked = true })
Here you have taken gender as a Enum
type and you have written the value for the radio button as a string
type- change "Male" to 0 and "Female" to 1.
With Spring Boot simply add: spring.jpa.show-sql=true to application.properties. This will show the query but without the actual parameters (you will see ? instead of each parameter).
The loc
parameter specifies in which corner of the bounding box the legend is placed. The default for loc
is loc="best"
which gives unpredictable results when the bbox_to_anchor
argument is used.
Therefore, when specifying bbox_to_anchor
, always specify loc
as well.
The default for bbox_to_anchor
is (0,0,1,1)
, which is a bounding box over the complete axes. If a different bounding box is specified, is is usually sufficient to use the first two values, which give (x0, y0) of the bounding box.
Below is an example where the bounding box is set to position (0.6,0.5)
(green dot) and different loc
parameters are tested. Because the legend extents outside the bounding box, the loc
parameter may be interpreted as "which corner of the legend shall be placed at position given by the 2-tuple bbox_to_anchor argument".
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = 6, 3
fig, axes = plt.subplots(ncols=3)
locs = ["upper left", "lower left", "center right"]
for l, ax in zip(locs, axes.flatten()):
ax.set_title(l)
ax.plot([1,2,3],[2,3,1], "b-", label="blue")
ax.plot([1,2,3],[1,2,1], "r-", label="red")
ax.legend(loc=l, bbox_to_anchor=(0.6,0.5))
ax.scatter((0.6),(0.5), s=81, c="limegreen", transform=ax.transAxes)
plt.tight_layout()
plt.show()
See especially this answer for a detailed explanation and the question What does a 4-element tuple argument for 'bbox_to_anchor' mean in matplotlib? .
bbox_transform
argument. If may make sense to use figure coordinates
ax.legend(bbox_to_anchor=(1,0), loc="lower right", bbox_transform=fig.transFigure)
It may not make too much sense to use data coordinates, but since you asked for it this would be done via bbox_transform=ax.transData
.
You really should have multiple input, e.g. one for firstname, middle names, lastname and another one for age. If you want to have some fun though you could try:
>>> input_given="join smith 25"
>>> chars="".join([i for i in input_given if not i.isdigit()])
>>> age=input_given.translate(None,chars)
>>> age
'25'
>>> name=input_given.replace(age,"").strip()
>>> name
'join smith'
This would of course fail if there is multiple numbers in the input. a quick check would be:
assert(age in input_given)
and also:
assert(len(name)<len(input_given))

I got the same question here. If the document is huge, it is not a good idea to use XmlDocument. The fact is that the first element is the root element, based on which XmlReader can be used to get the root element. Using XmlReader will be much more efficient than using XmlDocument as it doesn't require load the whole document into memory.
using (XmlReader reader = XmlReader.Create(<your_xml_file>)) {
while (reader.Read()) {
// first element is the root element
if (reader.NodeType == XmlNodeType.Element) {
System.Console.WriteLine(reader.Name);
break;
}
}
}
The solutions that search a file for a substring can also search a string, eg. find
or findstr
.
In your case, the easy solution would be to pipe a string into the command instead of supplying a filename eg.
case-sensitive string:
echo "abcdefg" | find "bcd"
ignore case of string:
echo "abcdefg" | find /I "bcd"
IF no match found, you will get a blank line response on CMD and %ERRORLEVEL% set to 1
(I don't have enough reputation to comment on toscho's answer.)
I have no experience with screen readers and I'm sure your points are valid.
However as far as using a keyboard to manipulate selects, it is trivial to select any option by using the keyboard:
TAB to the control
SPACE to open the select list
UP or DOWN arrows to scroll to the desired list item
ENTER to select the desired item
Only on ENTER does the onchange or (JQuery .change()) event fire.
While I personally would not use a form control for simple menus, there are many web applications that use form controls to change the presentation of the page (eg., sort order.) These can be implemented either by AJAX to load new content into the page, or, in older implementations, by triggering new page loads, which is essentially a page link.
IMHO these are valid uses of a form control.

You can use switch like this:
XML Layout
<RadioGroup
android:id="@+id/RG"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="@+id/R1"
android:layout_width="wrap_contnet"
android:layout_height="wrap_content"
android:text="R1" />
<RadioButton
android:id="@+id/R2"
android:layout_width="wrap_contnet"
android:layout_height="wrap_content"
android:text="R2" />
</RadioGroup>
And JAVA Activity
switch (RG.getCheckedRadioButtonId()) {
case R.id.R1:
regAuxiliar = ultimoRegistro;
case R.id.R2:
regAuxiliar = objRegistro;
default:
regAuxiliar = null; // none selected
}
You will also need to implement an onClick function with button or setOnCheckedChangeListener function to get required functionality.
A great Spring MVC quickstart archetype is available on GitHub, courtesy of kolorobot. Good instructions are provided on how to install it to your local Maven repo and use it to create a new Spring MVC project. He’s even helpfully included the Tomcat 7 Maven plugin in the archetypical project so that the newly created Spring MVC can be run from the command line without having to manually deploy it to an application server.
Kolorobot’s example application includes the following:
I find both YAML and JSON to be very effective. The only two things that really dictate when one is used over the other for me is one, what the language is used most popularly with. For example, if I'm using Java, Javascript, I'll use JSON. For Java, I'll use their own objects, which are pretty much JSON but lacking in some features, and convert it to JSON if I need to or make it in JSON in the first place. I do that because that's a common thing in Java and makes it easier for other Java developers to modify my code. The second thing is whether I'm using it for the program to remember attributes, or if the program is receiving instructions in the form of a config file, in this case I'll use YAML, because it's very easily human read, has nice looking syntax, and is very easy to modify, even if you have no idea how YAML works. Then, the program will read it and convert it to JSON, or whatever is preferred for that language.
In the end, it honestly doesn't matter. Both JSON and YAML are easily read by any experienced programmer.
<?php
header("Location: index.html");
?>
Just make sure nothing is actually written to the page prior to this code, or it won't work.
I don't believe there is a way to ignore a file in the repository. We often run into this with web.config and other configuration files.
Although not perfect, the solution I most often see and use is to have .default file and an nant task to create local copies.
For example, in the repo is a file called web.config.default
that has default values. Then create a nant task that will rename all the web.config.default
files to web.config
that can then be customized to local values. This task should be called when a new working copy is retrieved or a build is run.
You'll also need to ignore the web.config
file that is created so that it isn't committed to the repository.
You could use the Microsoft-specific function _getch:
#include <iostream>
#include <conio.h>
// ...
// ...
// ...
cout << "Press any key to continue..." << endl;
_getch();
cout << "Something" << endl;
It's far from pretty, but you could create a script or an alias that does something like this:
for c in $(git for-each-ref refs/tags/ --format='%(refname)'); do echo $c; git show --quiet "$c"; echo; done
If you want to add a row into the tbody
, get a reference to it and call its insertRow
method.
var tbodyRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
// Insert a row at the end of table
var newRow = tbodyRef.insertRow();
// Insert a cell at the end of the row
var newCell = newRow.insertCell();
// Append a text node to the cell
var newText = document.createTextNode('new row');
newCell.appendChild(newText);

This will give you a list of a single group, and the members of each group.

You can find all img element of parent div like below
$(this).find('img') or $(this).children('img')
If you want specific img element you can write like this
$(this).children('img:nth(n)')
// where n is the child place in parent list start from 0 onwards
Your div contain only one img element. So for this below is right
$(this).find("img").attr("alt")
OR
$(this).children("img").attr("alt")
But if your div contain more img element like below
<div class="mydiv">
<img src="test.png" alt="3">
<img src="test.png" alt="4">
</div>
then you can't use upper code to find alt value of second img element. So you can try this:
$(this).find("img:last-child").attr("alt")
OR
$(this).children("img:last-child").attr("alt")
This example shows a general idea that how you can find actual object within parent object. You can use classes to differentiate your child object. That is easy and fun. i.e.
<div class="mydiv">
<img class='first' src="test.png" alt="3">
<img class='second' src="test.png" alt="4">
</div>
You can do this as below :
$(this).find(".first").attr("alt")
and more specific as:
$(this).find("img.first").attr("alt")
You can use find or children as above code. For more visit Children http://api.jquery.com/children/ and Find http://api.jquery.com/find/. See example http://jsfiddle.net/lalitjs/Nx8a6/
Your best bet is going to be using your back-end language's tools for this. What language are you using? For Ruby, try json_printer.
The answer in "peculiarity" is correct and directly answers the question. As TimF answered, since the first parameter is in quotes, it is treated as a window title.
Also note that the Virtual PC options are being treated as options to the 'start' command itself, and are not valid for 'start'. This is true for all versions of Windows that have the 'start' command.
This problem with 'start' treating the quoted parameter as a title is even more annoying that just the posted problem. If you run this:
start "some valid command with spaces"
You get a new command prompt window, with the obvious result for a window title. Even more annoying, this new window doesn't inherit customized font, colors or window size, it's just the default for cmd.exe.
Obligatory .map
example:
var checkedVals = $('.theClass:checkbox:checked').map(function() {
return this.value;
}).get();
alert(checkedVals.join(","));
While most people will tell you to just use multiple repositories, I feel it's worth mentioning there are other solutions.
A single repository can contain multiple independent branches, called orphan branches. Orphan branches are completely separate from each other; they do not share histories.
git checkout --orphan BRANCHNAME
This creates a new branch, unrelated to your current branch. Each project should be in its own orphaned branch.
Now for whatever reason, git needs a bit of cleanup after an orphan checkout.
rm .git/index
rm -r *
Make sure everything is committed before deleting
Once the orphan branch is clean, you can use it normally.
Avoid all the hassle of orphan branches. Create two independent repositories, and push them to the same remote. Just use different branch names for each repo.
# repo 1
git push origin master:master-1
# repo 2
git push origin master:master-2
Tip : To make Auto size work , the call to sheet.autoSizeColumn(columnNumber)
should be made after populating the data into the excel.
Calling the method before populating the data, will have no effect.
Use LoadPatientRecords()
after a successful insertion.
Try the below code
private void btnSubmit_Click(object sender, EventArgs e)
{
if (btnSubmit.Text == "Clear")
{
btnSubmit.Text = "Submit";
txtpFirstName.Focus();
}
else
{
btnSubmit.Text = "Clear";
int result = AddPatientRecord();
if (result > 0)
{
MessageBox.Show("Insert Successful");
LoadPatientRecords();
}
else
MessageBox.Show("Insert Fail");
}
}
This kind of code perhaps should work for You

I'm not sure how they're functionally different. My current batch of OS X browsers don't show any difference.
I would assume they are all functionally the same due to legacy HTML attribute handling. Back in the day, any flag (Boolean) attribute need only be present, sans value, eg
<input readonly>
<option selected>
When XHTML came along, this syntax wasn't valid and values were required. Whilst the W3 specified using the attribute name as the value, I'm guessing most browser vendors decided to simply check for attribute existence.
If you want work on currencies, you have to use BigDecimal class. The problem is, there's no way to store some float numbers in memory (eg. you can store 5.3456, but not 5.3455), which can effects in bad calculations.
There's an nice article how to cooperate with BigDecimal and currencies:
http://www.javaworld.com/javaworld/jw-06-2001/jw-0601-cents.html
Yes, if bar is not None
is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar:
will execute if bar
is any kind of zero or empty container, or False
.
Many people do use not bar
where they really do mean bar is not None
.
It is much better to use
$value = mb_convert_encode($value,'HTML-ENTITIES','UTF-8');
Specially when you are using AJAX call for submitting 'ISO-8859-1' characters. It works for Chinese, Japanese, Czech, German and many more languages.

You won't be able to restore from 2012
to 2008
. You will be able to use a tool like red-gate SQL compare
to copy the schema etc (provided nothing 2012 specific is used). If you have data to copy across too, you can use their Data Compare
tool, and I think you get a 14 day free trial.
when you want to permit multiple array fields you will have to list array fields at last while permitting ,as given -
params.require(:questions).permit(:question, :user_id, answers: [], selected_answer: [] )

This seems as good a place as any to document another possible reason for the infamous PKIX error message. After spending far too long looking at the keystore and truststore contents and various java installation configs I realised that my issue was down to... a typo.
The typo meant that I was also using the keystore as the truststore. As my companies Root CA was not defined as a standalone cert in the keystore but only as part of a cert chain, and was not defined anywhere else (i.e. cacerts) I kept getting the PKIX error.
After a failed release (this is prod config, it was ok elsewhere) and two days of head scratching I finally saw the typo, and now all is good.
Hope this helps someone.
Solved in my case, i look at

For those who have the following error:
Error Code: 1290. The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
You can simply run this command to see which folder can load files from:
SHOW VARIABLES LIKE "secure_file_priv";
After that, you have to copy the files in that folder and run the query with LOAD DATA LOCAL INFILE
instead of LOAD DATA INFILE
.
PNG supports alphachannel transparency.
TIFF can have extended options I.e. Geo referencing for GIS applications.
I recommend only ever using JPEG for photographs, never for images like clip art, logos, text, diagrams, line art.
Favor PNG.
Doing it programmatically seems to work for me everytime. I have a build with the following line uncommented:
[[UIApplication sharedApplication] unregisterForRemoteNotifications];
I run it every time I want to unregister from PN. You might have to end the app explicitly from the recents list and play around with the Notification Center in Settings app to get it right.
Also, the UI prompt asking the user to register for PN may not show up. Not sure if has been disabled in any of the recent iOS versions.
In Stored procedure, you return the values using OUT
parameter ONLY. As you have defined two variables in your example:
outstaticip OUT VARCHAR2, outcount OUT NUMBER
Just assign the return values to the out parameters i.e. outstaticip
and outcount
and access them back from calling location. What I mean here is: when you call the stored procedure, you will be passing those two variables as well. After the stored procedure call, the variables will be populated with return values.
If you want to have RETURN value
as return from the PL/SQL call, then use FUNCTION
. Please note that in case, you would be able to return only one variable as return variable.
I suggest to use jQuery:
$('#mydiv')
.css('cursor', 'pointer')
.click(
function(){
alert('Click event is fired');
}
)
.hover(
function(){
$(this).css('background', '#ff00ff');
},
function(){
$(this).css('background', '');
}
);
This seems to be an efficient way to list vars with column number:
cbind(names(df))
Output:
[,1]
[1,] "A"
[2,] "B"
[3,] "C"
Sometimes I like to copy variables with position into my code so I use this function:
varnums<- function(x) {w=as.data.frame(c(1:length(colnames(x))),
paste0('# ',colnames(x)))
names(w)= c("# Var/Pos")
w}
varnums(df)
Output:
# Var/Pos
# A 1
# B 2
# C 3
We had a similar challenge to solve yesterday, and we solved it using a Google Apps Script!
The solution takes 5 mins to implement and I've documented with step-by-step instructions: https://github.com/nelsonic/html-form-send-email-via-google-script-without-server
Deploy the sample script as a Google Spreadsheet APP Script: google-script-just-email.js
remember to set the
TO_ADDRESS
in the script to where ever you want the emails to be sent.
and copy the APP URL so you can use it in the next step when you publish the script.
action
to the App URLUsing the sample html
file:
index.html
create a basic form.
remember to paste your APP URL into the form
action
in the HTML form.
Open the HTML Form in your Browser, Input some data & submit it!
Submit the form. You should see a confirmation that it was sent:
Open the inbox for the email address you set (above)
Everything about this is customisable, you can easily style/theme the form with your favourite CSS Library and Store the submitted data in a Google Spreadsheet for quick analysis.
The complete instructions are available on GitHub:
https://github.com/nelsonic/html-form-send-email-via-google-script-without-server
You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.
You should use this request:
curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod
TestClass.instance_methods
or without all the inherited methods
TestClass.instance_methods - Object.methods
(Was 'TestClass.methods - Object.methods')
Change
for(j = 0; j<=90; j+3)
to
for(j = 0; j<=90; j=j+3)
In my case I had to start a list of exclude extensions from the second line because xcopy ignored the first line.
If you do not mind recursive functions, here is a solution. I have also taken the liberty to include an exclusion-parameter in case there are one or more values you wish to maintain.
Code:
def flatten_dict(dictionary, exclude = [], delimiter ='_'):
flat_dict = dict()
for key, value in dictionary.items():
if isinstance(value, dict) and key not in exclude:
flatten_value_dict = flatten_dict(value, exclude, delimiter)
for k, v in flatten_value_dict.items():
flat_dict[f"{key}{delimiter}{k}"] = v
else:
flat_dict[key] = value
return flat_dict
Usage:
d = {'a':1, 'b':[1, 2], 'c':3, 'd':{'a':4, 'b':{'a':7, 'b':8}, 'c':6}, 'e':{'a':1,'b':2}}
flat_d = flatten_dict(dictionary=d, exclude=['e'], delimiter='.')
print(flat_d)
Output:
{'a': 1, 'b': [1, 2], 'c': 3, 'd.a': 4, 'd.b.a': 7, 'd.b.b': 8, 'd.c': 6, 'e': {'a': 1, 'b': 2}}
Assuming you have a form like this:
<form id="myForm" action="foo.php" method="post">
<input type="text" value="" />
<input type="submit" value="submit form" />
</form>
You can attach a onsubmit
-event with jQuery like this:
$('#myForm').submit(function() {
alert('Handler for .submit() called.');
return false;
});
If you return false
the form won't be submitted after the function, if you return true or nothing it will submit as usual.
See the jQuery documentation for more info.
This can be also thought of as a simple map reduce operation if you would like to think of it from a functional programming perspective.
import os
folders = [("home",".vim"),("home","zathura")]
[reduce(lambda x,y: os.path.join(x,y), each, "") for each in folders]
reduce
is builtin in Python 2.x. In Python 3.x it has been moved to itertools
However the accepted the answer is better.
This has been answered below but answering if you have a list of items that needs to be joined.
The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.
Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.
* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).
You can also get through it by the code below:
file=open(completefilepath,'r',encoding='utf8',errors="ignore")
file.read()
It should respond to ActionListeners, like this:
combo.addActionListener (new ActionListener () {
public void actionPerformed(ActionEvent e) {
doSomething();
}
});
@John Calsbeek rightly points out that addItemListener()
will work, too. You may get 2 ItemEvents
, though, one for the deselection of the previously selected item, and another for the selection of the new item. Just don't use both event types!
best solution: from jQuery v1.6 you can use prop() to add a property
$('#someid').prop('disabled', true);
to remove it, use removeProp()
$('#someid').removeProp('disabled');
Also note that the .removeProp() method should not be used to set these properties to false. Once a native property is removed, it cannot be added again. See .removeProp() for more information.
Executing the command iisreset
(cmd with elevated rights) fixed this issue for me.
It is stretching because align-self

I have been using the 3 dots, instead of 2. Three dots gives you a range that is open at the beginning and closed at the end, so if you do 2 queries for subsequent ranges, you can't get the same row back in both.

And, yes, always nice to use a scope!
for (int i = 0; i < clbIncludes.Items.Count; i++)
if (clbIncludes.GetItemChecked(i))
// Do selected stuff
else
// Do unselected stuff
If the the check is in indeterminate state, this will still return true. You may want to replace
if (clbIncludes.GetItemChecked(i))
with
if (clbIncludes.GetItemCheckState(i) == CheckState.Checked)
if you want to only include actually checked items.
In objective c you can use CGRectContainsPoint(yourview.frame, touchpoint)
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
UITouch* touch = [touches anyObject];
CGPoint touchpoint = [touch locationInView:self.view];
if( CGRectContainsPoint(yourview.frame, touchpoint) ) {
}else{
}}
In swift 3 yourview.frame.contains(touchpoint)
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let touch:UITouch = touches.first!
let touchpoint:CGPoint = touch.location(in: self.view)
if wheel.frame.contains(touchpoint) {
}else{
}
}
Another possible cause is that the clock of your machine is not synced (e.g. on Raspberry Pi). Check the current date/time using:
$ date
If the date and/or time is incorrect, try to update using:
$ sudo ntpdate -u time.nist.gov
Here's a simple way to accomplish this with jQuery that limits it to the appropriate input elements:
//prevent submission of forms when pressing Enter key in a text input
$(document).on('keypress', ':input:not(textarea):not([type=submit])', function (e) {
if (e.which == 13) e.preventDefault();
});

There some kind of old school 'Marxismic' way to the cast int -> bool without C4800 warnings of Microsoft's cl compiler - is to use negation of negation.
int i = 0;
bool bi = !!i;
int j = 1;
bool bj = !!j;
If you don't feel like using Math.Abs * -1 you can you this simple if statement :P
if (x > 0) {
x = -x;
}
Of course you could make this a function like this
function makeNegative(number) {
if (number > 0) {
number = -number;
}
}
makeNegative(-3) => -3 makeNegative(5) => -5
Hope this helps! Math.abs will likely work for you but if it doesn't this little

Check this answer for C++11. Basically, if you pass an lvalue the rvalue reference
From this article:
void f1(String s) {
vector<String> v;
v.push_back(std::move(s));
}
void f2(const String &s) {
vector<String> v;
v.push_back(s);
}
"For lvalue argument, ‘f1’ has one extra copy to pass the argument because it is by-value, while ‘f2’ has one extra copy to call push_back. So no difference; for rvalue argument, the compiler has to create a temporary ‘String(L“”)’ and pass the temporary to ‘f1’ or ‘f2’ anyway. Because ‘f2’ can take advantage of move ctor when the argument is a temporary (which is an rvalue), the costs to pass the argument are the same now for ‘f1’ and ‘f2’."
Continuing: " This means in C++11 we can get better performance by using pass-by-value approach when:
"
OTOH, for C++98 it is best to pass by reference - less data gets copied around. Passing const or non const depend of whether you need to change the argument or not.

It sounds like you'd be happer with a single table. The five having the same schema, and sometimes needing to be presented as if they came from one table point to putting it all in one table.
Add a new column which can be used to distinguish among the five languages (I'm assuming it's language that is different among the tables since you said it was for localization). Don't worry about having 4.5 million records. Any real database can handle that size no problem. Add the correct indexes, and you'll have no trouble dealing with them as a single table.
Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
Another easiest solution is to use Key.RETUEN
Click here for solution in detail
driver.findElement(By.name("q")).sendKeys("Selenium Tutorial", Key.RETURN);
Run this command :
sudo chown -R yourUser /home/yourUser/.composer
& :: comment
color C & :: set red font color
echo IMPORTANT INFORMATION
color & :: reset the color to default
Explanation:
&
separates two commands, so in this case color C
is the first command and :: set red font color
is the second one.
This statement with comment looks intuitively correct:
goto error1 :: handling the error
but it is not a valid use of the comment. It works only because goto
ignores all arguments past the first one. The proof is easy, this goto
will not fail either:
goto error1 handling the error
But similar attempt
color 17 :: grey on blue
fails executing the command due to 4 arguments unknown to the color
command: ::
, grey
, on
, blue
.
It will only work as:
color 17 & :: grey on blue
So the ampersand is inevitable.
Modify catalina.bat to add
set JPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"
and
CATALINA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
Optional: Add below line to run the debug mode by default when you run startup.bat
call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%
Eclipse or STS select debug configuration right click -> new
connection type -> Standard socket Attach
Port -> 8000 (as given in the CATALINA_OPTS)
Host -> localhost or IP address
If you are using AngularJS, you can use a custom directive for easy access:
define(['angular'], function () {
angular.module("selectionHelper", [])
.directive('selectOnClick', function () {
return {
restrict: 'A',
link: function (scope, element, attrs) {
element.on('click', function () {
this.select();
});
}
};
});
});
Now one can just use it like this:
<input type="text" select-on-click ... />
The sample is with requirejs - so the first and the last line can be skipped if using something else.
I know this question is old but I ran across it and I know other people might have the same problem. All these answers are okay but do not give proper detail or actual TRUE advice.
When wanting to style a specific section of a paragraph use the span tag.
<p><span style="font-weight:900">Andy Warhol</span> (August 6, 1928 - February 22, 1987)
was an American artist who was a leading figure in the visual art movement known as pop
art.</p>
Andy Warhol (August 6, 1928 - February 22, 1987) was an American artist who was a leading figure in the visual art movement known as pop art.
As the code shows, the span tag styles on the specified words: "Andy Warhol". You can further style a word using any CSS font styling codes.
{font-weight; font-size; text-decoration; font-family; margin; color}, etc.
Any of these and more can be used to style a word, group of words, or even specified paragraphs without having to add a class to the CSS Style Sheet Doc. I hope this helps someone!

I like to do something similar to this (though it is still very similar to using a cursor)
[code]
-- Table variable to hold list of things that need looping
DECLARE @holdStuff TABLE (
id INT IDENTITY(1,1) ,
isIterated BIT DEFAULT 0 ,
someInt INT ,
someBool BIT ,
otherStuff VARCHAR(200)
)
-- Populate your @holdStuff with... stuff
INSERT INTO @holdStuff (
someInt ,
someBool ,
otherStuff
)
SELECT
1 , -- someInt - int
1 , -- someBool - bit
'I like turtles' -- otherStuff - varchar(200)
UNION ALL
SELECT
42 , -- someInt - int
0 , -- someBool - bit
'something profound' -- otherStuff - varchar(200)
-- Loop tracking variables
DECLARE @tableCount INT
SET @tableCount = (SELECT COUNT(1) FROM [@holdStuff])
DECLARE @loopCount INT
SET @loopCount = 1
-- While loop variables
DECLARE @id INT
DECLARE @someInt INT
DECLARE @someBool BIT
DECLARE @otherStuff VARCHAR(200)
-- Loop through item in @holdStuff
WHILE (@loopCount <= @tableCount)
BEGIN
-- Increment the loopCount variable
SET @loopCount = @loopCount + 1
-- Grab the top unprocessed record
SELECT TOP 1
@id = id ,
@someInt = someInt ,
@someBool = someBool ,
@otherStuff = otherStuff
FROM @holdStuff
WHERE isIterated = 0
-- Update the grabbed record to be iterated
UPDATE @holdAccounts
SET isIterated = 1
WHERE id = @id
-- Execute your stored procedure
EXEC someRandomSp @someInt, @someBool, @otherStuff
END
[/code]
Note that you don't need the identity or the isIterated column on your temp/variable table, i just prefer to do it this way so i don't have to delete the top record from the collection as i iterate through the loop.
When this happens, look in the Errors window and the Output window to see if there are any error messages. If that doesn't help, try running svcutil.exe
manually, and see if there are any error messages.

I did answer at Can you use JavaScript to detect whether a user has closed a browser tab? closed a browser? or has left a browser?
Breadth-first search traverses a graph and in fact finds all paths from a starting node. Usually, BFS doesn't keep all paths, however. Instead, it updates a prededecessor function p to save the shortest path. You can easily modify the algorithm so that p(n)
doesn't only store one predecessor but a list of possible predecessors.
Then all possible paths are encoded in this function, and by traversing p recursively you get all possible path combinations.
One good pseudocode which uses this notation can be found in Introduction to Algorithms by Cormen et al. and has subsequently been used in many University scripts on the subject. A Google search for “BFS pseudocode predecessor p” uproots this hit on Stack Exchange.
What is the newline character in the C language: \r or \n?
The new-line may be thought of a some char
and it has the value of '\n'
. C11 5.2.1
This C new-line comes up in 3 places: C source code, as a single char
and as an end-of-line in file I/O when in text mode.
Many compilers will treat source text as ASCII. In that case, codes 10, sometimes 13, and sometimes paired 13,10 as new-line for source code. Had the source code been in another character set, different codes may be used. This new-line typically marks the end of a line of source code (actually a bit more complicated here), // comment, and # directives.
In source code, the 2 characters \
and n
represent the char
new-line as \n
. If ASCII is used, this char
would have the value of 10.
In file I/O, in text mode, upon reading the bytes of the input file (and stdin), depending on the environment, when bytes with the value(s) of 10 (Unix), 13,10, (*1) (Windows), 13 (Old Mac??) and other variations are translated in to a '\n'. Upon writing a file (or stdout), the reverse translation occurs.
Note: File I/O in binary mode makes no translation.
The '\r'
in source code is the carriage return char
.
(*1) A lone 13 and/or 10 may also translate into \n
.

On Yosemite, if the pid file is blocking Postgres from starting and you have a launchctl
daemon trying (and failing) to load the database daemons, then you'll need to unload the plist file:
$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Then remove the pid file
$ rm /usr/local/var/postgres/postmaster.pid
Then reload the launchctl
daemon
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
There is a simple way to solve this: you can execute php file by cron every 1 minute, and inside php executable file make "if" statement to execute when time "now" like this
<?/** suppose we have 1 hour and 1 minute inteval 01:01 */
$interval_source = "01:01";
$time_now = strtotime( "now" ) / 60;
$interval = substr($interval_source,0,2) * 60 + substr($interval_source,3,2);
if( $time_now % $interval == 0){
/** do cronjob */
}
This should be faster than iterating and will work regardless of shape.
numpy.isnan(myarray).any()
Edit: 30x faster:
import timeit
s = 'import numpy;a = numpy.arange(10000.).reshape((100,100));a[10,10]=numpy.nan'
ms = [
'numpy.isnan(a).any()',
'any(numpy.isnan(x) for x in a.flatten())']
for m in ms:
print " %.2f s" % timeit.Timer(m, s).timeit(1000), m
Results:
0.11 s numpy.isnan(a).any()
3.75 s any(numpy.isnan(x) for x in a.flatten())
Bonus: it works fine for non-array NumPy types:
>>> a = numpy.float64(42.)
>>> numpy.isnan(a).any()
False
>>> a = numpy.float64(numpy.nan)
>>> numpy.isnan(a).any()
True
Python allows for private class members with the double underscore prefix. This technique doesn't work at a module level so I am thinking this is a mistake in Dive Into Python.
Here is an example of private class functions:
class foo():
def bar(self): pass
def __bar(self): pass
f = foo()
f.bar() # this call succeeds
f.__bar() # this call fails
DIV is a generic block level container that can contain any other block or inline elements, including other DIV elements, whereas P is to wrap paragraphs (text).
The solutions above do not work on Linux.
Using .NET Core, attempting to execute new Uri("/home/foo/README.md")
results in an exception:
Unhandled Exception: System.UriFormatException: Invalid URI: The format of the URI could not be determined.
at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
at System.Uri..ctor(String uriString)
...
You need to give the CLR some hints about what sort of URL you have.
This works:
Uri fileUri = new Uri(new Uri("file://"), "home/foo/README.md");
...and the string returned by fileUri.ToString()
is "file:///home/foo/README.md"
This works on Windows, too.
new Uri(new Uri("file://"), @"C:\Users\foo\README.md").ToString()
...emits "file:///C:/Users/foo/README.md"
SQLDeveloper can do this.
You should get the awaiter (GetAwaiter()
) and end the wait for the completion of the asynchronous task (GetResult()
).
string code = GenerateCodeAsync().GetAwaiter().GetResult();
Change your second style to this:
input, select, textarea{
color: #ff0000;
}
At the moment, you are telling the form to change the text to black
once the focus is off. The above remedies that.
Also, it is a good idea to place the normal state styles ahead of the :focus
and :hover
styles in your stylesheet. That helps prevent this problem. So
input, select, textarea{
color: #ff0000;
}
textarea:focus, input:focus {
color: #ff0000;
}
.Scroll {
height:600px;
overflow-y: scroll;
}

Both if (one.length() > 0) {}

If there's any chance you can use the Expression Language to handle the parameter, you could
access it with empty param.foo
in an expression.

I used BBEdit for years, but recently converted to Panic's Coda.
I love Coda. It does everything that I need and now that I've begun programming plug-ins for it, it's become a far more rich tool. The support team are responsive and the community that is growing around it is fantastic. There is still a lot of room for improvement, but that's the cool thing about being part of the kind of community that surrounds it; you have a say in what that improvement is.
The java.util.logging.Level documentation does a good job of defining when to use a log level and the target audience of that log level.
Most of the confusion with java.util.logging
is in the tracing methods. It should be in the class level documentation but instead the Level.FINE
field provides a good overview:
FINE is a message level providing tracing information. All of FINE, FINER, and FINEST are intended for relatively detailed tracing. The exact meaning of the three levels will vary between subsystems, but in general, FINEST should be used for the most voluminous detailed output, FINER for somewhat less detailed output, and FINE for the lowest volume (and most important) messages. In general the FINE level should be used for information that will be broadly interesting to developers who do not have a specialized interest in the specific subsystem. FINE messages might include things like minor (recoverable) failures. Issues indicating potential performance problems are also worth logging as FINE.
One important thing to understand which is not mentioned in the level documentation is that call-site tracing information is logged at FINER
.
If you log a message as FINE
you will be able to configure logging system to see the log output with or without tracing log records surrounding the log message. So use FINE
only when tracing log records are not required as context to understand the log message.
FINER indicates a fairly detailed tracing message. By default logging calls for entering, returning, or throwing an exception are traced at this level.
In general, most use of FINER
should be left to call of entering, exiting, and throwing. That will for the most part reserve FINER
for call-site tracing when verbose logging is turned on.
When swallowing an expected exception it makes sense to use FINER
in some cases as the alternative to calling trace throwing
method since the exception is not actually thrown. This makes it look like a trace when it isn't a throw or an actual error that would be logged at a higher level.
FINEST indicates a highly detailed tracing message.
Use FINEST
when the tracing log message you are about to write requires context information about program control flow. You should also use FINEST for tracing messages that produce large amounts of output data.
CONFIG messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations. For example, CONFIG message might include the CPU type, the graphics depth, the GUI look-and-feel, etc.
The CONFIG
works well for assisting system admins with the items listed above.
Typically INFO messages will be written to the console or its equivalent. So the INFO level should only be used for reasonably significant messages that will make sense to end users and system administrators.
Examples of this are tracing program startup and shutdown.
In general WARNING messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.
An example use case could be exceptions thrown from AutoCloseable.close implementations.
In general SEVERE messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.
For example, if you have transaction in your program where if any one of the steps fail then all of the steps voided then SEVERE would be appropriate to use as the log level.
You can do:
import matplotlib.pyplot as plt
x = [1,2,3,4,5]
y = [2,1,3,6,7]
plt.plot(x, y, style='.-')
plt.show()
This will return a graph with the data points marked with a dot
The <p>
tag is a p
aragraph, and as such, it is a block element (as is, for instance, h1
and div
), whereas span
is an inline element (as, for instance, b
and a
)
Block elements by default create some whitespace above and below themselves, and nothing can be aligned next to them, unless you set a float
attribute to them.
Inline elements deal with spans of text inside a paragraph. They typically have no margins, and as such, you cannot, for instance, set a width
to it.
I have never done so, but it seems like
MATCH (head, head, body) AGAINST ('some words' IN BOOLEAN MODE)
Should give a double weight to matches found in the head.
Just read this comment on the docs page, Thought it might be of value to you:

It should be noted in the documentation that IN BOOLEAN MODE will almost always return a relevance of 1.0. In order to get a relevance that is meaningful, you'll need to:
SELECT MATCH('Content') AGAINST ('keyword1 keyword2') as Relevance
FROM table
WHERE MATCH ('Content') AGAINST('+keyword1+keyword2' IN BOOLEAN MODE)
HAVING Relevance > 0.2
ORDER BY Relevance DESC
Notice that you are doing a regular relevance query to obtain relevance factors combined with a WHERE clause that uses BOOLEAN MODE. The BOOLEAN MODE gives you the subset that fulfills the requirements of the BOOLEAN search, the relevance query fulfills the relevance factor, and the HAVING clause (in this case) ensures that the document is relevant to the search (i.e. documents that score less than 0.2 are considered irrelevant). This also allows you to order by relevance.
This may or may not be a bug in the way that IN BOOLEAN MODE operates, although the comments I've read on the mailing list suggest that IN BOOLEAN MODE's relevance ranking is not very complicated, thus lending itself poorly for actually providing relevant documents. BTW - I didn't notice a performance loss for doing this, since it appears MySQL only performs the FULLTEXT search once, even though the two MATCH clauses are different. Use EXPLAIN to prove this.
So it would seem you may not need to worry about calling the fulltext search twice, though you still should "use EXPLAIN to prove this"
In Xcode 4 and possibly before, in the run script build phase there is an option "Show enviroment variables in build phase". If selected this will show then on a olive green background in the build log.
This was still happening to me on version 6.3.9 on OSX. I downloaded 6.1.7 again to actually see the result grid again.
What a pain in the butt!
A slightly modified version of Sophie's answer which allows to output the *.d files to a different folder (I will only paste the interesting part that generates the dependency files):
$(OBJDIR)/%.o: %.cpp
# Generate dependency file
mkdir -p $(@D:$(OBJDIR)%=$(DEPDIR)%)
$(CXX) $(CXXFLAGS) $(CPPFLAGS) -MM -MT $@ $< -MF $(@:$(OBJDIR)/%.o=$(DEPDIR)/%.d)
# Generate object file
mkdir -p $(@D)
$(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $< -o $@
Note that the parameter
-MT $@
is used to ensure that the targets (i.e. the object file names) in the generated *.d files contain the full path to the *.o files and not just the file name.
I don't know why this parameter is NOT needed when using -MMD in combination with -c (as in Sophie's version). In this combination it seems to write the full path of the *.o files into the *.d files. Without this combination, -MMD also writes only the pure file names without any directory components into the *.d files. Maybe somebody knows why -MMD writes the full path when combined with -c. I have not found any hint in the g++ man page.
kubectl rollout restart deployment myapp
This is the current way to trigger a rolling update and leave the old replica sets in place for other operations provided by kubectl rollout
like rollbacks.
