Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:
What is Anonymous FTP?
Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".
…
Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.
These are general recommendations, though. Each FTP server may have its own guidelines.
For sample use of the ftp
command on anonymous FTP access, see appendix A:

You could use the jQuery $each method to loop through all the elements with class testimonial. i => is the index of the element in collection and val gives you the object of that particular element and you can use "val" to further access the properties of your element and check your condition.
$.each($('.testimonal'), function(i, val) {
if(your condition){
//your action
}
});
The reason why your full-width-div doesn't stretch 100% to your screen it's because of its parent "container" which occupies only about 80% of the screen.
If you want to make it stretch 100% to the screen either you make the "full-width-div" position fixed or use the "container-fluid" class instead of "container".

Your simple example from the question simply prints out these values with 2 digits - appending leading 0 if necessary.
You don't need to run Xcode 10.2 for iOS 12.2 support. You just need access to the appropriate folder in DeviceSupport.
A possible solution is
/Applications
. It's possible to have multiple Xcode versions in the same directory.Create a symbolic link in Terminal.app to have access to the 12.2 device support folder in Xcode 10.2
ln -s /Applications/Xcode102.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/12.2\ \(16E226\) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
You can move Xcode 10.2 to somewhere else but then you have to adjust the path.
Now Xcode 10.1 supports devices running iOS 12.2
In the windows when we open jupyter notebook in command prompt we can see the instructions in first 10 lines in that there is one instruction- "to open notebook, open this file in browser file://C:/Users/{username}/appdata/roaming/jupyetr/runtime/nbserver-xywz-open.html " , open this html with browser of your choice.
Basically you just have to map the procedure to the entity using Stored Procedure Mapping.
Once mapped, you use the regular method for adding an item in EF, and it will use your stored procedure instead.
Please see: This Link for a walkthrough. The result will be adding an entity like so (which will actually use your stored procedure)
using (var ctx = new SchoolDBEntities())
{
Student stud = new Student();
stud.StudentName = "New sp student";
stud.StandardId = 262;
ctx.Students.Add(stud);
ctx.SaveChanges();
}
dict((k, v) for k, v in points.items() if all(x < 5 for x in v))
You could choose to call .iteritems()
instead of .items()
if you're in Python 2 and points
may have a lot of entries.
all(x < 5 for x in v)
may be overkill if you know for sure each point will always be 2D only (in that case you might express the same constraint with an and
) but it will work fine;-).
It's a simple Mistake while adding a new file you just have to make sure that \
is added to the file before and the new file remain as it is
eg.
Check Out what to do if i want to add a new file named customer.cc
Example:
$test = "chees";
"${test}y";
It will output:
cheesy
It is exactly what you are looking for.
server.session.timeout=1200
server.servlet.session.timeout=10m
Just use x["error_msg"]
. If the property doesn't exist, it returns null
.
This is actually pretty easy to do. All you have to do is change the css.
Here's a fiddle with a very simple fade animation: http://jsfiddle.net/elthrasher/sNpjH/
To make it into a sliding animation, I first had to put my element in a box (that's the slide-container), then I added another element to replace the one that was leaving, just because I thought it would look nice. Take it out and the example will still work.
I changed the animation css from 'fade' to 'slide' but please note that these are the names I gave it. I could have written slide animation css named 'fade' or anything else for that matter.
The important part is what's in the css. Here's the original 'fade' css:
.fade-hide, .fade-show {
-webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
}
.fade-hide {
opacity:1;
}
.fade-hide.fade-hide-active {
opacity:0;
}
.fade-show {
opacity:0;
}
.fade-show.fade-show-active {
opacity:1;
}
This code changes the opacity of the element from 0 (completely transparent) to 1 (completely opaque) and back again. The solution is to leave opacity alone and instead change the top (or left, if you want to move left-right).
.slide-hide, .slide-show {
-webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
-moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
-o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
}
.slide-hide {
position: relative;
top: 0;
}
.slide-hide.slide-hide-active {
position: absolute;
top: -100px;
}
.slide-show {
position: absolute;
top: 100px;
}
.slide-show.slide-show-active {
position: relative;
top: 0px;
}
I'm also changing from relative to absolute positioning so only one of the elements takes up space in the container at a time.
Here's the finished product: http://jsfiddle.net/elthrasher/Uz2Dk/. Hope this helps!
For the sake of anyone also using visual studio from a windows environment:
I realized that I could see my module installed when i ran pip install
py pip install [moduleName]
py pip list
However debugging in visual studio was getting "module not found". Oddly, i was successfully running import [moduleName]
when i ran the interpreter in powershell.
Reason:
visual studio was using the wrong interpreter at:
C:\Users\[username]\AppData\Local\Programs\Python\Python37\
What I REALLY wanted was visual studio to use the virtualenv that i setup for my project. To do this, right click Python Environments in "solution explorer", select Add Virtual Environment..., and then select the folder where you created your virtual environment. Then, under project settings, under the General tab, select your virtual environment in the dropdown.
Now visual studio should be using the same interpreter and everything should play nice!
I've done exactly this on Windows. I have a local .html page that I use as a "dashboard" for all my current work. In addition to the usual links, I've been able to add clickable links that open MS-Word documents, Excel spreadsheets, open my IDE, ssh to servers, etc. It is a little involved but here's how I did it ...
First, update the Windows registry. Your browser handles usual protocols like http, https, ftp. You can define your own protocol and a handler to be invoked when a link of that protocol-type is clicked. Here's the config (run with regedit
)
[HKEY_CLASSES_ROOT\mydb]
@="URL:MyDB Document"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\mydb\shell]
@="open"
[HKEY_CLASSES_ROOT\mydb\shell\open]
[HKEY_CLASSES_ROOT\mydb\shell\open\command]
@="wscript C:\_opt\Dashboard\Dashboard.vbs \"%1\""
With this, when I have a link like <a href="mydb:open:ProjectX.docx">ProjectX</a>
, clicking it will invoke C:\_opt\Dashboard\Dashboard.vbs
passing it the command line parameter open:ProjectX.docx
. My VBS code looks at this parameter and does the necessary thing (in this case, because it ends in .docx, it invokes MS-Word with ProjectX.docx
as the parameter to it.
Now, I've written my handler in VBS only because it is very old code (like 15+ years). I haven't tried it, but you might be able to write a Python handler, Dashboard.py
, instead. I'll leave it up to you to write your own handler. For your scripts, your link could be href="mydb:runpy:whatever.py"
(the runpy:
prefix tells your handle to run with Python).
XCode 11.3.1:
When I want to use an Swift inner class in a objc code, it does not compile for ther error "undefined symbol"(for bother inner class and outer class), I checked the generated "-swift.h" header and both classes are there.
After trying for hours I convert the inner class to a normal class and it compiles.
I clean the project, delete the DerivedData folder and it compiles.
This is what I tried for a right outer join [as per my requirement]:
m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink,
by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"),
by.y=c("company_permalink"), all.y=TRUE)
This worked.
=arrayformula(if(isblank(B2:B),iferror(1/0),mmult(sign(B2:B=TRANSPOSE(A2:A)),A2:A)))
I got this from a good tutorial - can't remember the title - probably about using MMult
Since Python 2.6.X you might want to use:
"my {0} string: {1}".format("cool", "Hello there!")
Here is my version of the same task::
import os, glob, shutil
def make_dir(path):
if not os.path.isdir(path):
os.mkdir(path)
def copy_dir(source_item, destination_item):
if os.path.isdir(source_item):
make_dir(destination_item)
sub_items = glob.glob(source_item + '/*')
for sub_item in sub_items:
copy_dir(sub_item, destination_item + '/' + sub_item.split('/')[-1])
else:
shutil.copy(source_item, destination_item)

I've seen it used as a slight performance hack for a "dynamic type" pointer (in the section "Under the Hood"):
But here is the tricky trick I used to get fast performance for small types: if the value being held can fit inside of a void*, I don't actually bother allocating a new object, I force it into the pointer itself using placement new.
A good solution that uses generics:
template <typename T,unsigned S>
inline unsigned arraysize(const T (&v)[S]) { return S; }
Then simply call arraysize(_Array);
to get the length of the array.
Sometimes the problem may be if you import
that like this:
const Vue = window.vue;
this may overwrite the original Vue
reference.
I recommend setting the display options inside a context manager so that it only affects a single output. I usually prefer "pretty" html-output, and define a function force_show_all(df)
for displaying the DataFrame df
:
from IPython.core.display import display, HTML
def force_show_all(df):
with pd.option_context('display.max_rows', None, 'display.max_columns', None, 'display.width', None):
display(HTML(df.to_html()))
# ... now when you're ready to fully display df:
force_show_all(df)
As others have mentioned, please be cautious to only call this on a reasonably-sized dataframe.
As mentioned before you can use --extra-vars (-e) , but instead of specifying the pwd on the commandline so it doesn't end up in the history files you can save it to an environment variable. This way it also goes away when you close the session.
read -s PASS
ansible windows -i hosts -m win_ping -e "ansible_password=$PASS"
Or use Series.tolist
or Series.any
:
>>> s = pd.Series(list('abc'))
>>> s
0 a
1 b
2 c
dtype: object
>>> 'a' in s.tolist()
True
>>> (s=='a').any()
True
Series.tolist
makes a list about of a Series
, and the other one i am just getting a boolean Series
from a regular Series
, then checking if there are any True
s in the boolean Series
.
No. There is no way of knowing which object it came from.
s
and obj.subObj
both simply have references to the same object.
You could also do:
var obj = { subObj: {foo: 'hello world'} };
var obj2 = {};
obj2.subObj = obj.subObj;
var s = obj.subObj;
You now have three references, obj.subObj
, obj2.subObj
, and s
, to the same object. None of them is special.
The answers above are great. If you are in need of parsing all numbers out of a string that are nonconsecutive then the following may be of some help:
string input = "1-205-330-2342";
string result = Regex.Replace(input, @"[^\d]", "");
Console.WriteLine(result); // >> 12053302342
2018 now. You don't need any extensions for auto-imports in Javascript (as long as you have checkjs: true
in your jsconfig.json
file) and TypeScript.
There are two types of auto imports: the add missing import quick fix which shows up as a lightbulb on errors:
And the auto import suggestions. These show up a suggestion items as you type. Accepting an auto import suggestion automatically adds the import at the top of the file
Both should work out of the box with JavaScript and TypeScript. If auto imports still do not work for you, please open an issue
Like others, I've found that the plugin can be made (via JS) to shrink when the container shrinks, but afterwards will not grow when it expands.
The issue is that the original FB.XFBML.parse()
creates a set of child nodes with fixed styles in the document tree, and later invocations will not properly clean out the old nodes. If you do it yourself in your code, all is well.
Facebook HTML (I merely added ID elements to what Facebook provided, to avoid any selector accidents):
<div id="divFacebookFeed" class="fb-page" data-href="..." ...>
<blockquote id="bqNoFeed" cite="(your URL)" class="fb-xfbml-parse-ignore">
<a href="(your URL)">Your Site</a>
</blockquote>
</div>
...JQuery code to resize the widget to 500px and preserve the inner fallback element:
var bq = $('#bqNoFeed').detach();
var fbdiv = $('#divFacebookFeed');
fbdiv.attr('data-width', 500);
fbdiv.empty();
fbdiv.append(bq);
FB.XFBML.parse();
Try this
var fd = new FormData();
fd.append('fname', 'test.wav');
fd.append('data', soundBlob);
$.ajax({
type: 'POST',
url: '/upload.php',
data: fd,
processData: false,
contentType: false
}).done(function(data) {
console.log(data);
});
You need to use the FormData API and set the jQuery.ajax
's processData
and contentType
to false
.
The solution given didn't work for me on the desktop, it just showed both divs, although the mobile only showed the mobile div. So I did a little search and found the min-width option. I updated my code to the following and it works fine now :)
CSS:
@media all and (min-width: 480px) {
.deskContent {display:block;}
.phoneContent {display:none;}
}
@media all and (max-width: 479px) {
.deskContent {display:none;}
.phoneContent {display:block;}
}
HTML:
<div class="deskContent">Content for desktop</div>
<div class="phoneContent">Content for mobile</div>
By using NULL
without any quotes.
UPDATE `tablename` SET `fieldName` = NULL;
With Chrome, Firefox, Safari, Edge, and Webview you can natively use the fetch API which makes this a lot easier, and much more terse.
If you need support for IE or older browsers, you can also use the fetch polyfill.
let url = 'https://example.com';
fetch(url)
.then(res => res.json())
.then((out) => {
console.log('Checkout this JSON! ', out);
})
.catch(err => { throw err });
Even though Node.js does not have this method built-in, you can use node-fetch which allows for the exact same implementation.
The easiest way might be to get it from NuGet:
http://www.nuget.org/packages/System.Windows.Interactivity.WPF/
Make a state machine that operates on one basic principle: is the current character a number.
Optimizations are possible.
Use display: inline-block
, though you need to wrap it inside a DIV to keep it from actually displaying inline. Tested in Safari.

A slightly updated answer (since I ran into this problem in different circumstances.)
When you connect to a server using SSL, the first thing the server does is present a certificate which says "I am api.dropbox.com." The certificate has a "subject" and the subject has a "CN" (short for "common name".) The certificate may also have one or more "subjectAltNames". When node.js connects to a server, node.js fetches this certificate, and then verifies that the domain name it thinks it's connecting to (api.dropbox.com) matches either the subject's CN or one of the altnames. Note that, in node 0.10.x, if you connect using an IP, the IP address has to be in the altnames - node.js will not try to verify the IP against the CN.
Setting the rejectUnauthorized
flag to false will get around this check, but first of all if the server is giving you different credentials than you are expecting, something fishy is going on, and second this will also bypass other checks - it's not a good idea if you're connecting over the Internet.
If you are using node >= 0.11.x, you can also specify a checkServerIdentity: function(host, cert)
function to the tls module, which should return undefined
if you want to allow the connection and throw an exception otherwise (although I don't know if request
will proxy this flag through to tls for you.) It can be handy to declare such a function and console.log(host, cert);
to figure out what the heck is going on.
By calling method
public class a
{
void sum(int i,int k)
{
System.out.println("THe sum of the number="+(i+k));
}
}
class b
{
public static void main(String[] args)
{
a vc=new a();
vc.sum(10 , 20);
}
}
If at all you going to check with double equal "==" then check null with object ref like
if(null == obj)
instead of
if(obj == null)
because if you mistype single equal if(obj = null) it will return true (assigning object returns success (which is 'true' in value).
This works:

Just want to add since it might be of interest to someone, that you may think about the problem the other way as well. I am not sure if that is of interest here, but I find it relevant.
What I mean by the other way is to say "strip anything that aren't what I am looking for, i.e. if you only want the 'ding' you could say:
var strippedText = ("1 ding ?").replace(/[^a-zA-Z]/g, '');
Which basically mean "remove anything which is nog a,b,c,d....Z (any letter).
For me the problem was in that I had not yet ran composer update
for this new project/fork. The command failed silently, nothing happened.
After running composer update
it worked.
What are CN, OU, DC?
From RFC2253 (UTF-8 String Representation of Distinguished Names):
String X.500 AttributeType ------------------------------ CN commonName L localityName ST stateOrProvinceName O organizationName OU organizationalUnitName C countryName STREET streetAddress DC domainComponent UID userid
What does the string from that query mean?
The string ("CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
) is a path from an hierarchical structure (DIT = Directory Information Tree) and should be read from right (root) to left (leaf).
It is a DN (Distinguished Name) (a series of comma-separated key/value pairs used to identify entries uniquely in the directory hierarchy). The DN is actually the entry's fully qualified name.
Here you can see an example where I added some more possible entries.
The actual path is represented using green.
The following paths represent DNs (and their value depends on what you want to get after the query is run):
"DC=gp,DC=gl,DC=google,DC=com"
"OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
"OU=People,DC=gp,DC=gl,DC=google,DC=com"
"OU=Groups,DC=gp,DC=gl,DC=google,DC=com"
"CN=QA-Romania,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
"CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com"
"CN=Diana Anton,OU=People,DC=gp,DC=gl,DC=google,DC=com"
Try using the Worksheet.Protect

Dim ws As Worksheet
Set ws = ActiveSheet
ws.Protect DrawingObjects:=True, Contents:=True, _

You should, however, be concerned about including the password in your VBA code. You don't necessarily need a password if you're only trying to put up a simple barrier that keeps a user from making small mistakes like deleting formulas, etc.
Also, if you want to see how to do certain things in VBA in Excel, try recording a Macro and looking at the code it generates. That's a good way to get started in VBA.
overflow: auto;
overflow-y: hidden;
For IE8: -ms-overflow-y: hidden;

To hide Y:

My solution is to use FontAwesome and then add library images as text! You just need the Unicodes and they are found here: FontAwesome Reference File forUnicodes
Here is an example state filter:
<select name='state' style='height: 45px; font-family:Arial, FontAwesome;'>
<option value=''> All States</option>

new File(".").getAbsolutePath()
Yes. But as the variable is concerned it is overwrite (Giving new value to variable. Giving new definition to the function is Override). Just don't declare the variable but initialize (change) in the constructor or static block.
The value will get reflected when using in the blocks of parent class
if the variable is static then change the value during initialization itself with static block,
class Son extends Dad {
static {
me = "son";
}
}
or else change in constructor.
You can also change the value later in any blocks. It will get reflected in super class
There is no equivalent of C# async/await in Java at the language level. A concept known as Fibers aka cooperative threads aka lightweight threads could be an interesting alternative. You can find Java libraries providing support for fibers.
Java libraries implementing Fibers
You can read this article (from Quasar) for a nice introduction to fibers. It covers what threads are, how fibers can be implemented on the JVM and has some Quasar specific code.
select * from xxx where dates between '2012-10-10' and '2012-10-12'
I always use YYYY-MM-DD
in my views and never had any issue. Plus, it is readable and non equivocal.
You should be aware that using BETWEEN
might not return what you expect with a DATETIME
field, since it would eliminate records dated '2012-10-12 08:00'
for example.
I would rather use where dates >= '2012-10-10' and dates < '2012-10-13'
(lower than next day)
So, After taking a while I figured out that the old push certificate generating service also exists.
You get two options:
Those who want to achieve the old style .p12 certificate can get it from second option. I have not used the first option yet as most of the third-party push notification service providers still need the .p12 format certificate.
Use:
#include<iostream>
#include<string>
std::string intToString(int num);
int main()
{
int integer = 4782151;
std::string integerAsStr = intToString(integer);
std::cout << "integer = " << integer << std::endl;
std::cout << "integerAsStr = " << integerAsStr << std::endl;
return 0;
}
std::string intToString(int num)
{
std::string numAsStr;
bool isNegative = num < 0;
if(isNegative) num*=-1;
do
{
char toInsert = (num % 10) + 48;
numAsStr.insert(0, 1, toInsert);
num /= 10;
}while (num);
return isNegative? numAsStr.insert(0, 1, '-') : numAsStr;
}
This happened to me on Ubuntu 18.04.2 after I tried to install Python3.7 from the deadsnakes repo.
Solution was this
1) cd /usr/lib/python3/dist-packages/
2) sudo ln -s apt_pkg.cpython-36m-x86_64-linux-gnu.so apt_pkg.so
I liked the way how $rootscope.emit
was used to achieve intercommunication. I suggest the clean and performance effective solution without polluting global space.

the question is a little confused. timestamps are not UTC - they're a Unix thing. the date might be UTC? assuming it is, and if you're using Python 3.2+, simple-date makes this trivial:
>>> SimpleDate(date(2011,1,1), tz='utc').timestamp
1293840000.0
if you actually have the year, month and day you don't need to create the date
:
>>> SimpleDate(2011,1,1, tz='utc').timestamp
1293840000.0
and if the date is in some other timezone (this matters because we're assuming midnight without an associated time):
>>> SimpleDate(date(2011,1,1), tz='America/New_York').timestamp
1293858000.0
[the idea behind simple-date is to collect all python's date and time stuff in one consistent class, so you can do any conversion. so, for example, it will also go the other way:
>>> SimpleDate(1293858000, tz='utc').date
datetime.date(2011, 1, 1)

For a bandpass filter, ws is a tuple containing the lower and upper corner frequencies. These represent the digital frequency where the filter response is 3 dB less than the passband.
wp is a tuple containing the stop band digital frequencies. They represent the location where the maximum attenuation begins.
gpass is the maximum attenutation in the passband in dB while gstop is the attentuation in the stopbands.
Say, for example, you wanted to design a filter for a sampling rate of 8000 samples/sec having corner frequencies of 300 and 3100 Hz. The Nyquist frequency is the sample rate divided by two, or in this example, 4000 Hz. The equivalent digital frequency is 1.0. The two corner frequencies are then 300/4000 and 3100/4000.
Now lets say you wanted the stopbands to be down 30 dB +/- 100 Hz from the corner frequencies. Thus, your stopbands would start at 200 and 3200 Hz resulting in the digital frequencies of 200/4000 and 3200/4000.
To create your filter, you'd call buttord as
fs = 8000.0
fso2 = fs/2
N,wn = scipy.signal.buttord(ws=[300/fso2,3100/fso2], wp=[200/fs02,3200/fs02],
gpass=0.0, gstop=30.0)
The length of the resulting filter will be dependent upon the depth of the stop bands and the steepness of the response curve which is determined by the difference between the corner frequency and stopband frequency.
http://caniuse.com/#search=::after
::after

are better to use as they're supported in every major browser other than Internet Explorer at least 5 versions back. Internet Explorer has complete support in version 9+ and partial support in version 8.
Is this what you're looking for?
.Modal::after{
content:url('blackCarrot.png'); /* with class ModalCarrot ??*/
position:relative; /*or absolute*/
z-index:100000; /*a number that's more than the modal box*/

top:10px;
}
.ModalCarrot{
position:absolute;
left:50%;
margin-left:-8px;
top:-16px;

If not, can you explain a little better?
or you could use jQuery, like Joshua said:

Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.
The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback)
function from fs
module:
var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
if (err) {
// append failed
} else {
// done
}
})
But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options])
function instead:
var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
flags: 'a' // 'a' means appending (old data will be preserved)
})
logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again
Node will keep appending new data to your file every time you'll call .write
, until your application will be closed, or until you'll manually close the stream calling .end
:
logger.end() // close string
Talking in terms of performance :
TL;DR
Use isInstance or instanceof which have similar performance. isAssignableFrom is slightly slower.
Sorted by performance:
Based on a benchmark of 2000 iterations on JAVA 8 Windows x64, with 20 warmup iterations.
In theory
Using a soft like bytecode viewer we can translate each operator into bytecode.
In the context of:
package foo;
public class Benchmark
{
public static final Object a = new A();
public static final Object b = new B();
...
}
JAVA:
b instanceof A;
Bytecode:
getstatic foo/Benchmark.b:java.lang.Object
instanceof foo/A
JAVA:
A.class.isInstance(b);
Bytecode:
ldc Lfoo/A; (org.objectweb.asm.Type)
getstatic foo/Benchmark.b:java.lang.Object
invokevirtual java/lang/Class isInstance((Ljava/lang/Object;)Z);
JAVA:
A.class.isAssignableFrom(b.getClass());
Bytecode:
ldc Lfoo/A; (org.objectweb.asm.Type)
getstatic foo/Benchmark.b:java.lang.Object
invokevirtual java/lang/Object getClass(()Ljava/lang/Class;);
invokevirtual java/lang/Class isAssignableFrom((Ljava/lang/Class;)Z);
Measuring how many bytecode instructions are used by each operator, we could expect instanceof and isInstance to be faster than isAssignableFrom. However, the actual performance is NOT determined by the bytecode but by the machine code (which is platform dependent). Let's do a micro benchmark for each of the operators.
The benchmark
Credit: As advised by @aleksandr-dubinsky, and thanks to @yura for providing the base code, here is a JMH benchmark (see this tuning guide):
class A {}
class B extends A {}
public class Benchmark {
public static final Object a = new A();
public static final Object b = new B();
@Benchmark
@BenchmarkMode(Mode.Throughput)
@OutputTimeUnit(TimeUnit.MICROSECONDS)
public boolean testInstanceOf()
{
return b instanceof A;
}
@Benchmark
@BenchmarkMode(Mode.Throughput)
@OutputTimeUnit(TimeUnit.MICROSECONDS)
public boolean testIsInstance()
{
return A.class.isInstance(b);
}
@Benchmark
@BenchmarkMode(Mode.Throughput)
@OutputTimeUnit(TimeUnit.MICROSECONDS)
public boolean testIsAssignableFrom()
{
return A.class.isAssignableFrom(b.getClass());
}
public static void main(String[] args) throws RunnerException {
Options opt = new OptionsBuilder()
.include(TestPerf2.class.getSimpleName())
.warmupIterations(20)
.measurementIterations(2000)
.forks(1)
.build();
new Runner(opt).run();
}
}
Gave the following results (score is a number of operations in a time unit, so the higher the score the better):
Benchmark Mode Cnt Score Error Units
Benchmark.testIsInstance thrpt 2000 373,061 ± 0,115 ops/us
Benchmark.testInstanceOf thrpt 2000 371,047 ± 0,131 ops/us
Benchmark.testIsAssignableFrom thrpt 2000 363,648 ± 0,289 ops/us
Warning
instanceof
in the context of your code might get optimized more easily than an isInstance
for example... To give you an example, take the following loop:
class A{}
class B extends A{}
A b = new B();
boolean execute(){
return A.class.isAssignableFrom(b.getClass());
// return A.class.isInstance(b);
// return b instanceof A;
}
// Warmup the code
for (int i = 0; i < 100; ++i)
execute();
// Time it
int count = 100000;
final long start = System.nanoTime();
for(int i=0; i<count; i++){
execute();
}
final long elapsed = System.nanoTime() - start;
Thanks to the JIT, the code is optimized at some point and we get:
Note
Originally this post was doing its own benchmark using a for loop in raw JAVA, which gave unreliable results as some optimization like Just In Time can eliminate the loop. So it was mostly measuring how long did the JIT compiler take to optimize the loop: see Performance test independent of the number of iterations for more details

In order to have this result:
{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}
that holds the same data as:
{
"aoColumnDefs": [
{ "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
{ "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
{ "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
]
}
you could use this code:
JSONObject jo = new JSONObject();
Collection<JSONObject> items = new ArrayList<JSONObject>();
JSONObject item1 = new JSONObject();
item1.put("aDataSort", new JSONArray(0, 1));
item1.put("aTargets", new JSONArray(0));

items.add(item2);

For elementwise multiplication of matrix
objects, you can use numpy.multiply
:
import numpy as np
a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])
np.multiply(a,b)
Result
array([[ 5, 12],
[21, 32]])
However, you should really use array
instead of matrix
. matrix
objects have all sorts of horrible incompatibilities with regular ndarrays. With ndarrays, you can just use *
for elementwise multiplication:
a * b
If you're on Python 3.5+, you don't even lose the ability to perform matrix multiplication with an operator, because @
does matrix multiplication now:
a @ b # matrix multiplication

Use this one:
Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")
With rng.Validation
.Delete 'delete previous validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Formula1:="='" & ws.Name & "'!" & range1.Address
End With
Note that when you're using Dim range1, rng As range
, only rng
has type of Range
, but range1
is Variant
. That's why I'm using Dim range1 As Range, rng As Range
.
About meaning of parameters you can read is MSDN, but in short:
Type:=xlValidateList
means validation type, in that case you should select value from listAlertStyle:=xlValidAlertStop
specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.Operator:= xlBetween
is odd. It can be used only if two formulas are provided for validation.Formula1:="='" & ws.Name & "'!" & range1.Address
for list data validation provides address of list with values (in format =Sheet!A1:A5
)Depends on what the while loop is doing. If there is a chance that it will block for a long time, use TimerTask
to schedule a task to set a stopExecution
flag, and also .interrupt()

With just a time condition in the loop, it could sit there forever waiting for input or a lock (then again, may not be a problem for you).
The proper way of using NSLog, as the warning tries to explain, is the use of a formatter, instead of passing in a literal:
Instead of:
NSString *digit = [[sender titlelabel] text];
NSLog(digit);
Use:
NSString *digit = [[sender titlelabel] text];
NSLog(@"%@",digit);
It will still work doing that first way, but doing it this way will get rid of the warning.
If you want to set the same value on a collection of rows, you can use the update() method combined with any query term to update all rows in one query:
some_list = ModelClass.objects.filter(some condition).values('id')
ModelClass.objects.filter(pk__in=some_list).update(foo=bar)
If you want to update a collection of rows with different values depending on some condition, you can in best case batch the updates according to values. Let's say you have 1000 rows where you want to set a column to one of X values, then you could prepare the batches beforehand and then only run X update-queries (each essentially having the form of the first example above) + the initial SELECT-query.
If every row requires a unique value there is no way to avoid one query per update. Perhaps look into other architectures like CQRS/Event sourcing if you need performance in this latter case.

If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python
is interpreted as a variable, which you have not defined.

You can do the following with Unnamed Columns:
file.csv
,A,B,C
0,1,2,3
1,4,5,6
2,7,8,9
#read file
df = pd.read_csv('file.csv')
Method 1: Delete Unnamed Columns
# delete one by one like column is 'Unnamed: 0' so use it's name
df.drop('Unnamed: 0', axis=1, inplace=True)
#delete all Unnamed Columns in a single code of line using regex
df.drop(df.filter(regex="Unnamed"),axis=1, inplace=True)
Method 2: Rename Unnamed Columns
df.rename(columns = {'Unnamed: 0':'Name'}, inplace = True)
If you want to write out with a blank header as in the input file, just choose 'Name' above to be ''.
Subscribing what basil said in a comment to the question itself, if method = RequestMethod.GET
you can use @RequestParam List<String> groupVal
.
Then calling the service with the list of params is as simple as:
API_URL?groupVal=kkk,ccc,mmm
Using simple html,
<div>
<object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
</object>
</div>
Or jquery,
<script>
$("#mydiv")
.html('<object data="http://your-website-domain"/>');
</script>
You should not try to do this directly. Design your tasks to work with a CancellationToken, and cancel them this way.
In addition, I would recommend changing your main thread to function via a CancellationToken as well. Calling Thread.Abort()
is a bad idea - it can lead to various problems that are very difficult to diagnose. Instead, that thread can use the same Cancellation that your tasks use - and the same CancellationTokenSource
can be used to trigger the cancellation of all of your tasks and your main thread.
This will lead to a far simpler, and safer, design.
Better way, you can also use EditText onFocusChange listener to check whether user has done editing: (Need not rely on user pressing the Done or Enter button on Soft keyboard)
((EditText)findViewById(R.id.youredittext)).setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
// When focus is lost check that the text field has valid values.
if (!hasFocus) { {
// Validate youredittext
}
}
});
Note : For more than one EditText, you can also let your class implement View.OnFocusChangeListener
then set the listeners to each of you EditText and validate them as below
((EditText)findViewById(R.id.edittext1)).setOnFocusChangeListener(this);
((EditText)findViewById(R.id.edittext2)).setOnFocusChangeListener(this);
@Override
public void onFocusChange(View v, boolean hasFocus) {
// When focus is lost check that the text field has valid values.
if (!hasFocus) {
switch (view.getId()) {
case R.id.edittext1:
// Validate EditText1
break;
case R.id.edittext2:
// Validate EditText2
break;
}
}
}
You're obviously not closing your file descriptors before opening new ones. Are you on windows or linux?
The solution that worked for me. Delete this folder:
workspace/.metadata/.plugins/org.eclipse.e4.workbench
In swift 3, Xcode 8.2:- checking battery state level
//Add observer
NotificationCenter.default.addObserver(self, selector: #selector(batteryStateDidChange), name: NSNotification.Name.UIDeviceBatteryStateDidChange, object: nil)
//Fired when battery level changes
func batteryStateDidChange(notification: NSNotification){
//perform manipulation here
}
I tested all the cases in the latest Chrome, Firefox, Safari in 2019.

I found a solution on Stack Overflow for Java program run configurations which also works for JUnit run configurations.
You can get the full command executed by your configuration on the Debug tab, or more specifically the Debug view.
- Run your application
- Go to your Debug perspective
- There should be an entry in there (in the Debug View) for the app you've just executed
- Right-click the node which references java.exe or javaw.exe and select Properties In the dialog that pops up you'll see the Command Line which includes all jars, parameters, etc
No. The HTML 5 spec mentions:
The method and formmethod content attributes are enumerated attributes with the following keywords and states:
The keyword get, mapping to the state GET, indicating the HTTP GET method. The GET method should only request and retrieve data and should have no other effect.
The keyword post, mapping to the state POST, indicating the HTTP POST method. The POST method requests that the server accept the submitted form's data to be processed, which may result in an item being added to a database, the creation of a new web page resource, the updating of the existing page, or all of the mentioned outcomes.
The keyword dialog, mapping to the state dialog, indicating that submitting the form is intended to close the dialog box in which the form finds itself, if any, and otherwise not submit.
The invalid value default for these attributes is the GET state
I.e. HTML forms only support GET and POST as HTTP request methods. A workaround for this is to tunnel other methods through POST by using a hidden form field which is read by the server and the request dispatched accordingly.
However, GET, POST, PUT and DELETE are supported by the implementations of XMLHttpRequest (i.e. AJAX calls) in all the major web browsers (IE, Firefox, Safari, Chrome, Opera).
I have joined the answer from Lucas and "ASP.NET MVC Helpers, Merging two object htmlAttributes together" and plus controllerName to following code:

"~/Content/Images/Image.bmp",
new { width=108, height=129, alt="Edit" })

using System.Reflection;
using System.Web.Mvc;
namespace MVC.Extensions
{
public static class MvcHtmlStringExt
{
// Extension method
public static MvcHtmlString ActionImage(
this HtmlHelper html,
string action,

object htmlAttributes)
{
//https://stackoverflow.com/questions/4896439/action-image-mvc3-razor
var url = new UrlHelper(html.ViewContext.RequestContext);

var imgBuilder = new TagBuilder("img");
imgBuilder.MergeAttribute("src", url.Content(imagePath));
var dictAttributes = htmlAttributes.ToDictionary();
if (dictAttributes != null)
{
foreach (var attribute in dictAttributes)
{
imgBuilder.MergeAttribute(attribute.Key, attribute.Value.ToString(), true);

}
string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);
// build the <a> tag

Be careful, when you register by
LocalBroadcastManager.getInstance(this).registerReceiver()
you can't unregister by
unregisterReceiver()
you must use
LocalBroadcastManager.getInstance(this).unregisterReceiver()
or app will crash, log as follow:

I know this question was asked a while ago, but in case useful, the here
package is really helpful for not having to reference specific file paths and making code more portable. It will automatically define your working directory as the one that your .Rproj
file resides in, so the following will often suffice without having to define the file path to your working directory:
library(here)
if (!dir.exists(here(outputDir))) {dir.create(here(outputDir))}
I tried the other answers here as well as a few others. I even stopped and restarted the SQL services. Nothing worked.
However, restarting my computer did work.

I am much late to the party but today I faced the same error and how I resolved was simple. My scenario was similar to this given code I was making DB transactions inside of nested for-each loops.
The problem is as a Single DB transaction takes a little bit time longer than for-each loop so once the earlier transaction is not complete then the new traction throws an exception, so the solution is to create a new object in the for-each loop where you are making a db transaction.
For the above mentioned scenarios the solution will be like this:
foreach (RivWorks.Model.Negotiation.AutoNegotiationDetails companyFeedDetail in companyFeedDetailList)
{
private RivWorks.Model.Negotiation.RIV_Entities _dbRiv = RivWorks.Model.Stores.RivEntities(AppSettings.RivWorkEntities_connString);
if (companyFeedDetail.FeedSourceTable.ToUpper() == "AUTO")
{
var company = (from a in _dbRiv.Company.Include("Product") where a.CompanyId == companyFeedDetail.CompanyId select a).First();
foreach (RivWorks.Model.NegotiationAutos.Auto sourceProduct in client.Auto)
{
foreach (RivWorks.Model.Negotiation.Product targetProduct in company.Product)
{
if (targetProduct.alternateProductID == sourceProduct.AutoID)
{
found = true;
break;
}
}
if (!found)
{
var newProduct = new RivWorks.Model.Negotiation.Product();
newProduct.alternateProductID = sourceProduct.AutoID;
newProduct.isFromFeed = true;
newProduct.isDeleted = false;
newProduct.SKU = sourceProduct.StockNumber;
company.Product.Add(newProduct);
}
}
_dbRiv.SaveChanges(); // ### THIS BREAKS ### //
}
}
Either in SQL or in report code (as per adolf garlic's function suggestion)
At this moment in time, I'd do it in the report. I have very few reports against a busy OLTP server and an underwhelmed report server. If I had a different mix I'd do it in SQL.
Either way is acceptable...
If you are using Minikube, there is a magic command!
$ minikube tunnel
Hopefully someone can save a few minutes with this.
Reference link https://minikube.sigs.k8s.io/docs/handbook/accessing/#using-minikube-tunnel
For Spring 2
val hostName = InetAddress.getLocalHost().hostName
var webServerPort: Int = 0
@Configuration
class ApplicationListenerWebServerInitialized : ApplicationListener<WebServerInitializedEvent> {
override fun onApplicationEvent(event: WebServerInitializedEvent) {
webServerPort = event.webServer.port
}
}
then you can use also webServerPort
from anywhere...
Technically possible. You would probably reference employees_ce in deductions and employees_sn. But why don't you merge employees_sn and employees_ce? I see no reason why you have two table. No one to many relationship. And (not in this example) many columns.
If you do two references for one column, an employee must have an entry in both tables.
This error is shown when your Xcode installation is too old and the related device you are using is updated to latest version.
There are multiple ways to solve this issues.
1. Update your Xcode installation.
This is by far the simplest method. Just update your Xcode installation to the latest stable version and things would start working again.
Note: Please update your OS as well if Xcode doesn't support your current OS. Which brings us to...
2. Manually copying Device Disk Image. No update needed.
This is the clever way around. You don't have to update your Xcode installation or your OS for this.
First open the XCode.dmg and select Show Package Contents.
Phase 1: Getting the downloaded Xcode ready.
Steps:
Now, a new finder window opens. Follow the instructions below to copy the disk image.
Phase 2: Copying the Developer Disk Image.
Steps:
Note: For step 6, You can copy the disk image you want to copy as well, i.e. copy the latest only. It's the last folder in the hierarchy here.
This ends the Phase 2, Copying the disk image. Now in the next phase, we will update the developer disk image of our Xcode installed on our device.
Phase 3: Upadting the Xcode's developer disk image.
Now, close all the finder windows for faster operation and less confusion.
We are now going to update our Xcode's disk image for iOS Platform.
Steps:
Finder window updates or opens a new window with Contents as the main directory.
Note: SKIP step 12 if you copied only the latest disk image i.e. the last folder in the hierarchy.
Now, Paste the developer disk image we copied from Phase 2 here.
Paste
here.If everything worked properly, your Xcode has new developer disk image. Close the finder now, and open Xcode. The error should be gone by now.
Reminder: Don't forget to unmount the Xcode now from finder as well.
I was able to select (check) a radio input button by using this Javascript code in Firefox 72, within a Web Extension option page to LOAD the value:
var reloadItem = browser.storage.sync.get('reload_mode');
reloadItem.then((response) => {
if (response["reload_mode"] == "Periodic") {
document.querySelector('input[name=reload_mode][value="Periodic"]').click();
} else if (response["reload_mode"] == "Page Bottom") {
document.querySelector('input[name=reload_mode][value="Page Bottom"]').click();
} else {
document.querySelector('input[name=reload_mode][value="Both"]').click();
}
});
Where the associated code to SAVE the value was:
reload_mode: document.querySelector('input[name=reload_mode]:checked').value
Given HTML like the following:
<input type="radio" id="periodic" name="reload_mode" value="Periodic">
<label for="periodic">Periodic</label><br>
<input type="radio" id="bottom" name="reload_mode" value="Page Bottom">
<label for="bottom">Page Bottom</label><br>
<input type="radio" id="both" name="reload_mode" value="Both">
<label for="both">Both</label></br></br>
Here's what to do:
Create a new Project in Objective-C
Create a new .swift
file
Click on your Xcode Project file
Click on Build Settings
Find the Search bar and search for Defines Module.
Change value to Yes.
Search Product Module Name.
Change the value to the name of your project.
In App delegate, add the following : #import "YourProjectName-Swift.h"
Note: Whenever you want to use your Swift file you must be import following line :
#import "YourProjectName-Swift.h"
Try replacing apt-get
with yum
as Amazon Linux based AMI uses the yum

jQuery is a JavaScript library, that can be used for communicating (selecting html elements, attaching event listeners, animations etc.) with the DOM, creating and consuming AJAX requests, as well as other things in a more easier way rather than using plain JavaScript. jQuery is written in JavaScript. It should be mentioned that browsers parse only HTML, CSS and JavaScript files. Hence, all JavaScript libraries/frameworks (jQuery, Knockout, Angular) are written in JavaScript or in languages like TypeScript that transconpiles to JavaScript (e.g. Angular 2). They provide you the opportunity to write less lines of codes or to create interfaces following patterns like MVC (e.g. Angular), MVVM (e.g. Knockout) as well as other patterns, but under the hood, they are all result in a JavaScript file.
An example in order to understand why using jQuery you write less do more is the following.
Let we have the following input element
<input id="button1" type="button" value="clickMe"/>
Also, let that we want when someone clicks on the button to be notified through an alert box showing to the user a 'Hello' message.
If we had to do this using plain JavaScript, we would have written the following:
document.getElementById("button1")
.addEventListener('click', function(){
alert("Hello");
});
On the other hand, if we were using jQuery, we would had achieved the same result by just writing this:
$('#button1').click(function(){
alert("Hello");
});
Using jQuery makes things more clear than using plain JavaScript for the same purpose. (write less do more is jQuery's moto)
Furthermore, jQuery handles pretty well the theme of browser compatibility, you can use their API pretty easily without wondering too much as if you should do in case of using plain JavaScript.
Below I have added snippets for the code above:
document.getElementById("button1")_x000D_
.addEventListener('click', function(){ _x000D_
alert("Hello");_x000D_
});
_x000D_
<input id="button1" type="button" value="clickMe"/>
_x000D_
$('#button1').click(function(){ alert("Hello"); });
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input id="button1" type="button" value="clickMe"/>
_x000D_
In my case, everything was set up correctly, but my Docker
infrastructure needed more RAM. I'm using Docker for Mac, where default RAM was around 1 GB, and as MySQL uses around 1.5Gb of RAM ( and probably was crashing ??? ), changing the Docker RAM utilization level to 3-4 Gb solved the issue.
A little late to the party, but if you are looking for a solution like Yury's the following code will help you identify if the issue is related to a self-sign certificate and, if so ignore the self-sign error. You could obviously check for other SSL errors if you so desired.
The code we use (courtesy of Microsoft - http://msdn.microsoft.com/en-us/library/office/dd633677(v=exchg.80).aspx) is as follows:
private static bool CertificateValidationCallBack(
object sender,
System.Security.Cryptography.X509Certificates.X509Certificate certificate,
System.Security.Cryptography.X509Certificates.X509Chain chain,
System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
// If the certificate is a valid, signed certificate, return true.
if (sslPolicyErrors == System.Net.Security.SslPolicyErrors.None)
{
return true;
}
// If there are errors in the certificate chain, look at each error to determine the cause.
if ((sslPolicyErrors & System.Net.Security.SslPolicyErrors.RemoteCertificateChainErrors) != 0)
{
if (chain != null && chain.ChainStatus != null)
{
foreach (System.Security.Cryptography.X509Certificates.X509ChainStatus status in chain.ChainStatus)
{
if ((certificate.Subject == certificate.Issuer) &&
(status.Status == System.Security.Cryptography.X509Certificates.X509ChainStatusFlags.UntrustedRoot))
{
// Self-signed certificates with an untrusted root are valid.
continue;
}
else
{
if (status.Status != System.Security.Cryptography.X509Certificates.X509ChainStatusFlags.NoError)
{
// If there are any other errors in the certificate chain, the certificate is invalid,
// so the method returns false.
return false;
}
}
}
}
// When processing reaches this line, the only errors in the certificate chain are
// untrusted root errors for self-signed certificates. These certificates are valid
// for default Exchange server installations, so return true.
return true;
}
else
{
// In all other cases, return false.
return false;
}
}

We just released pako https://github.com/nodeca/pako , port of zlib to javascript. I think that's now the fastest js implementation of deflate / inflate / gzip / ungzip. Also, it has democratic MIT licence. Pako supports all zlib options and it's results are binary equal.
Example:
var inflate = require('pako/lib/inflate').inflate;
var text = inflate(zipped, {to: 'string'});
There you go: (a-zA-Z)
function codeToChar( number ) {
if ( number >= 0 && number <= 25 ) // a-z
number = number + 97;
else if ( number >= 26 && number <= 51 ) // A-Z
number = number + (65-26);
else
return false; // range error
return String.fromCharCode( number );
}
input: 0-51, or it will return false (range error);
OR:
var codeToChar = function() {
var abc = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ".split("");
return function( code ) {
return abc[code];
};
})();
returns undefined in case of range error. NOTE: the array will be created only once and because of closure it will be available for the the new codeToChar function. I guess it's even faster then the first method (it's just a lookup basically).
How about the following, where y is the name of your matrix and you are looking for the maximum in the entire matrix:
row(y)[y==max(y)]
if you want to extract the row:
y[row(y)[y==max(y)],] # this returns unsorted rows.
To return sorted rows use:
y[sort(row(y)[y==max(y)]),]
The advantage of this approach is that you can change the conditional inside to anything you need. Also, using col(y)
and location of the hanging comma you can also extract columns.
y[,col(y)[y==max(y)]]
To find just the row for the max in a particular column, say column 2 you could use:
seq(along=y[,2])[y[,2]==max(y[,2])]
again the conditional is flexible to look for different requirements.
See Phil Spector's excellent "An introduction to S and S-Plus" Chapter 5 for additional ideas.
In C# 7 it's possible to use a when clause in a case statement.
int age = 12;
switch (age)
{
case int i when i >=1 && i <= 8:
System.Console.WriteLine("You are only " + age + " years old. You must be kidding right. Please fill in your *real* age.");
break;
case int i when i >=9 && i <= 15:
System.Console.WriteLine("You are only " + age + " years old. That's too young!");
break;
case int i when i >=16 && i <= 100:
System.Console.WriteLine("You are " + age + " years old. Perfect.");
break;
default:
System.Console.WriteLine("You an old person.");
break;

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.
Using all these resources, you will be able to create an flawless android location detection app.
You will first need to listen for current location of user. You can use any of below libraries to quick start.
This library provide last known location, location updates
With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.
Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.
Google Maps Android API utility library
If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.
Simple, smooth animation for route / polylines on google maps using projections. (WIP)
This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.
For this specific use-case using try..except..else
is the cleanest solution, the else
clause will be executed if no exception was raised.
NOTE: The else
clause must follow all except
clauses
for i in iterator:
try:
# Do something.
except:
# Handle exception
else:
# Continue doing something
I used the QueryBuilder to get the data,
$query=$this->dm->createQueryBuilder('AppBundle:DocumentName')
->field('fieldName')->notEqual(null);
$data=$query->getQuery()->execute();
for my auth server... this works. i like to have options for /auth for my own humanized readability... or also i have it configured by port/upstream for machine to machine.

You may want to use one of the implementing class of java.util.Set<E>
Interface e.g. java.util.HashSet<String>
collection class.
A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element. As implied by its name, this interface models the mathematical set abstraction.
Hi me also faced same issue , solved using below steps:
Add internet permission in your android application
Check the manually your default application is able access internet or not if not its problem of your emulator , check in your internet connection in your pc
try below method to connect net in your pc
try explicitly specifying DNS server settings, this worked for me.
In Eclipse:
Window>Preferences>Android>Launch
Default emulator options: -dns-server 8.8.8.8,8.8.4.4**
check : check if you are using more than one internet connection to your pc like one is LAN second one is Modem , so disable all lan or modem .
LocalDate localDate = LocalDate.parse( new SimpleDateFormat("yyyy-MM-dd").format(date) );
Something like this that i answer in another question
public class Snippet {
public static void main(String[] args) {
int [][]lst = new int[10][10];
for (int[] arr : lst) {
System.out.println(Arrays.toString(arr));
}
}
}
I haven't used connect by prior, but a quick search shows it's used for tree structures. In SQL Server, you use common table expressions to get similar functionality.
My solution was to hide the badge, then display it when the user focuses on a form input - thus still adhering to Google's T&Cs.
Note: The reCAPTCHA I was tweaking had been generated by a WordPress plugin, so you may need to wrap the reCAPTCHA with a <div class="inv-recaptcha-holder"> ... </div>
yourself.
CSS
.inv-recaptcha-holder {
visibility: hidden;
opacity: 0;
transition: linear opacity 1s;
}
.inv-recaptcha-holder.show {
visibility: visible;
opacity: 1;
transition: linear opacity 1s;
}
jQuery
$(document).ready(function () {
$('form input, form textarea').on( 'focus', function() {
$('.inv-recaptcha-holder').addClass( 'show' );
});
});
Obviously you can change the jQuery selector to target specific forms if necessary.
Several of the suggestions above use global variables. This is not a good solution for the problem. The count is specific to one element, and you can use jQuery's data
function to bind an item of data to an element:
$('#counter').data('count', 0);
$('#update').click(function(){
$('#counter').html(function(){
var $this = $(this),
count = $this.data('count') + 1;
$this.data('count', count);
return count;
});
});
Note also that this uses the callback syntax of html
to make the code more fluent and fast.
Put this in a macro (IT WILL CHECK THROUGH ROW 75000, YOU CAN LOWER THE NUMBER IF YOU WOULD LIKE
Columns("E:E").Select
Selection.AutoFilter
ActiveSheet.Range("$E$1:$E$75000").AutoFilter Field:=1, Criteria1:="none"
Range("E2:E75000").SpecialCells(xlCellTypeVisible).Select
Selection.EntireRow.Delete
ActiveSheet.Cells.EntireRow.Hidden = False
ActiveSheet.Range("$E$1:$E$75000").AutoFilter Field:=1
Columns("E:E").Select
Selection.AutoFilter
Range("E2").Select
Range("A1").Select
Do you mean shapefile as in an Esri shapefile? Either way, you should be able to perform the conversion using ogr2ogr, which is available in the GDAL packages. You need the .shp
file and ideally the corresponding .dbf
file (which will provide contextual information).
Also, consider using a tool like MapShaper to reduce the complexity of your shapefiles before transforming them into KML; you'll reduce filesize substantially depending on how much detail you need.
It's under "GCC 4.2 Preprocessing" (or just put "prepro" in the search box)...
...however, for the life of me I can't get it to work.
I have my standard Debug and Release configurations, and I want to define DEBUG=1 in the debugging configuration. But after adding it as a value:
(in the settings window) > Preprocessor Macros : DEBUG=1
#if DEBUG
printf("DEBUG is set!");
#endif
...never prints/gets called. It's driving me crazy...
UITableView
has a tableHeaderView
property. Set that to whatever view you want up there.
Use a new UIView
as a container, add a text label and an image view to that new UIView
, then set tableHeaderView
to the new view.
For example, in a UITableViewController
:
-(void)viewDidLoad
{
// ...
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
[headerView addSubview:imageView];
UILabel *labelView = [[UILabel alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
[headerView addSubview:labelView];
self.tableView.tableHeaderView = headerView;
[imageView release];
[labelView release];
[headerView release];
// ...
}
I've had a stubborn image too, that wouldn't go away by setting the Image and InitialImage to null. To remove the image from the pictureBox for good, I had to use the code below, by calling Application.DoEvents() repeatedly:
Application.DoEvents();
if (_pictureBox.Image != null)
_pictureBox.Image.Dispose();
_pictureBox.Image = null;
Application.DoEvents();
if (_pictureBox.InitialImage != null)
_pictureBox.InitialImage.Dispose();
_pictureBox.InitialImage = null;
_pictureBox.Update();
Application.DoEvents();
_pictureBox.Refresh();
Usually there are 2 types of seed data required.
In my experience I was always coming across the need for these two types of data. So I put together a small gem that extends Rails' seeds and lets you add multiple common seed files under db/seeds/ and any environmental seed data under db/seeds/ENV for example db/seeds/development.
I have found this approach is enough to give my seed data some structure and gives me the power to setup my development or staging environment in a known state just by running:
rake db:setup
Fixtures are fragile and flakey to maintain, as are regular sql dumps.
I was getting this error when I was trying to ssh into an ec2 instance on the private subnet from the bastion, to fix this issue, you've to run (ssh-add -K) as follow.
Step 1: run "chmod 400 myEC2Key.pem"
Step 2: run "ssh-add -K ./myEC2Key.pem" on your local machine
Step 3: ssh -i myEC2Key.pem [email protected]
Step 4: Now try to ssh to EC2 instance that is on a private subnet without specifying the key, for example, try ssh ec2-user@ipaddress.
Hope this will help.
Note: This solution is for Mac.
Not sure if this answers the question. But I know this took me a while to figure out. I was looping through a website and all of sudden the name of the authors weren't there anymore. So needed a check statement.
if type(author) == type(None):
my if body
else:
my else body
Author can be any variable in this case, and None
can be any type that you are checking for.
Note: you should use the accepted answer if possible. It's better than mine.
It's quite easy with the GD library.
It's built in usually, you probably have it (use phpinfo()
to check)
$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagejpeg($image, "folder/file.jpg");
The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).
$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");
This only works if allow_url_fopen
is true
(it is by default)
Yes you can do this.
*[id^='term-']{
[css here]
}
This will select all ids that start with 'term-'
.
As for the reason for not doing this, I see where it would be preferable to select this way; as for style, I wouldn't do it myself, but it's possible.
The local variables have a lifetime which extends only inside the block in which it is defined. The moment the control goes outside the block in which the local variable is defined, the storage for the variable is no more allocated (not guaranteed). Therefore, using the memory address of the variable outside the lifetime area of the variable will be undefined behaviour.
On the other hand you can do the following.
char *str_to_ret = malloc (sizeof (char) * required_size);
.
.
.
return str_to_ret;
And use the str_to_ret
instead. And when return
ing str_to_ret
, the address allocated by malloc
will be returned. The memory allocated by malloc
is allocated from the heap, which has a lifetime which spans the entire execution of the program. Therefore, you can access the memory location from any block and any time while the program is running.
Also note that it is a good practice that after you have done with the allocated memory block, free
it to save from memory leaks. Once you free the memory, you can't access that block again.
see event.data
commentbtn.bind('click', { id: '12', name: 'Chuck Norris' }, function(event) {
var data = event.data;
alert(data.id);
alert(data.name);
});
If your data is initialized before binding the event, then simply capture those variables in a closure.
// assuming id and name are defined in this scope
commentBtn.click(function() {
alert(id), alert(name);
});
I had this problem and none of the suggestions from several posts worked, I tried them all. My problem turned out that the table I was creating is nested in another table, inheriting on its properties. I needed to override the container table.
In this example, SuColTable is class on the table.
.SuColTable tr {
border: none !important;
}
.SuColTable td {
border-spacing: 0 !important;
border: none !important;
margin: 0 !important;
padding-top: 0 !important;
padding-bottom: 0 !important;
padding-right: 0 !important;
}
.SuColTable {
border-collapse: collapse !important;
border: none !important;
border-spacing: 0 !important;
border-collapse: separate !important;
padding-left: 0 !important;
padding-top: 0 !important;
padding-bottom: 0 !important;
}
// all padding would be padding: 0 !important
The border-collapse, border:none and border-spacing get rid of table/row/column line. The padding 0 calls get rid the padding from the container table. I had to including !important on every style for it work, in order override the container table styles.
I have padding_top, left and bottom (instead of only padding) because I have two other classes that control the padding_right.
line-height: 0px;
Line-height zero makes the row one line high. If you have several lines, they are compressed into one line.
Use the event on handleChange
to figure out the element that has changed and then update it. For that you might need to change some property to identify it and update it.
See fiddle https://jsfiddle.net/69z2wepo/6164/
[root@host]# mysqladmin -u root -p drop [DB]
Enter password:******
One more way,
git rebase -i ad0389efc1a79b1f9c4dd6061dca6edc1d5bb78a (C's hash)
and
git push origin master -f
pick the hash that you want to use it as a base, and the above command should make it interactive so you can squash all the top messages ( you need to leave the oldest )
Include sites-available/default
in sites-enabled/default
. It requires only one line.
In sites-enabled/default
(new config version?):
It seems that the include path is relative to the file that included it
include sites-available/default;
See the include
documentation.
I believe that certain versions of nginx allows including/linking to other files purely by having a single line with the relative path to the included file. (At least that's what it looked like in some "inherited" config files I've been using, until a new nginx version broke them.)
In sites-enabled/default
(old config version?):
It seems that the include path is relative to the current file
../sites-available/default
The error means, that Angular doesn't know what to do when you put a formControl
on a div
.
To fix this, you have two options.
formControlName
on an element, that is supported by Angular out of the box. Those are: input
, textarea
and select
.ControlValueAccessor
interface. By doing so, you're telling Angular "how to access the value of your control" (hence the name). Or in simple terms: What to do, when you put a formControlName
on an element, that doesn't naturally have a value associated with it.Now, implementing the ControlValueAccessor
interface can be a bit daunting at first. Especially because there isn't much good documentation of this out there and you need to add a lot of boilerplate to your code. So let me try to break this down in some simple-to-follow steps.
In order to implement the ControlValueAccessor
, you need to create a new component (or directive). Move the code related to your form control there. Like this it will also be easily reusable. Having a control already inside a component might be the reason in the first place, why you need to implement the ControlValueAccessor
interface, because otherwise you will not be able to use your custom component together with Angular forms.
Implementing the ControlValueAccessor
interface is quite verbose, here's the boilerplate that comes with it:
import {Component, OnInit, forwardRef} from '@angular/core';
import {ControlValueAccessor, FormControl, NG_VALUE_ACCESSOR} from '@angular/forms';
@Component({
selector: 'app-custom-input',
templateUrl: './custom-input.component.html',
styleUrls: ['./custom-input.component.scss'],
// a) copy paste this providers property (adjust the component name in the forward ref)
providers: [
{
provide: NG_VALUE_ACCESSOR,
useExisting: forwardRef(() => CustomInputComponent),
multi: true
}
]
})
// b) Add "implements ControlValueAccessor"
export class CustomInputComponent implements ControlValueAccessor {
// c) copy paste this code
onChange: any = () => {}
onTouch: any = () => {}
registerOnChange(fn: any): void {
this.onChange = fn;
}
registerOnTouched(fn: any): void {
this.onTouch = fn;
}
// d) copy paste this code
writeValue(input: string) {
// TODO
}
So what are the individual parts doing?
ControlValueAccessor
interfaceControlValueAccessor
interfaceonChange
and onTouch
with it's own implementation during runtime, such that you can then call those functions. So this point is important to understand: You don't need to implement onChange and onTouch yourself (other than the initial empty implementation). The only thing your doing with (c) is to let Angular attach it's own functions to your class. Why? So you can then call the onChange
and onTouch
methods provided by Angular at the appropriate time. We'll see how this works down below.writeValue
method works in the next section, when we implement it. I've put it here, so all required properties on ControlValueAccessor
are implemented and your code still compiles.What writeValue
does, is to do something inside your custom component, when the form control is changed on the outside. So for example, if you have named your custom form control component app-custom-input
and you'd be using it in the parent component like this:
<form [formGroup]="form">
<app-custom-input formControlName="myFormControl"></app-custom-input>
</form>
then writeValue
gets triggered whenever the parent component somehow changes the value of myFormControl
. This could be for example during the initialization of the form (this.form = this.formBuilder.group({myFormControl: ""});
) or on a form reset this.form.reset();
.
What you'll typically want to do if the value of the form control changes on the outside, is to write it to a local variable which represents the form control value. For example, if your CustomInputComponent
revolves around a text based form control, it could look like this:
writeValue(input: string) {
this.input = input;
}
and in the html of CustomInputComponent
:
<input type="text"
[ngModel]="input">
You could also write it directly to the input element as described in the Angular docs.
Now you have handled what happens inside of your component when something changes outside. Now let's look at the other direction. How do you inform the outside world when something changes inside of your component?
The next step is to inform the parent component about changes inside of your CustomInputComponent
. This is where the onChange
and onTouch
functions from (c) from above come into play. By calling those functions you can inform the outside about changes inside your component. In order to propagate changes of the value to the outside, you need to call onChange with the new value as the argument. For example, if the user types something in the input
field in your custom component, you call onChange
with the updated value:
<input type="text"
[ngModel]="input"
(ngModelChange)="onChange($event)">
If you check the implementation (c) from above again, you'll see what's happening: Angular bound it's own implementation to the onChange
class property. That implementation expects one argument, which is the updated control value. What you're doing now is you're calling that method and thus letting Angular know about the change. Angular will now go ahead and change the form value on the outside. This is the key part in all this. You told Angular when it should update the form control and with what value by calling onChange
. You've given it the means to "access the control value".
By the way: The name onChange
is chosen by me. You could choose anything here, for example propagateChange
or similar. However you name it though, it will be the same function that takes one argument, that is provided by Angular and that is bound to your class by the registerOnChange
method during runtime.
Since form controls can be "touched", you should also give Angular the means to understand when your custom form control is touched. You can do it, you guessed it, by calling the onTouch
function. So for our example here, if you want to stay compliant with how Angular is doing it for the out-of-the-box form controls, you should call onTouch
when the input field is blurred:
<input type="text"
[(ngModel)]="input"
(ngModelChange)="onChange($event)"
(blur)="onTouch()">
Again, onTouch
is a name chosen by me, but what it's actual function is provided by Angular and it takes zero arguments. Which makes sense, since you're just letting Angular know, that the form control has been touched.
So how does that look when it comes all together? It should look like this:
// custom-input.component.ts
import {Component, OnInit, forwardRef} from '@angular/core';
import {ControlValueAccessor, FormControl, NG_VALUE_ACCESSOR} from '@angular/forms';
@Component({
selector: 'app-custom-input',
templateUrl: './custom-input.component.html',
styleUrls: ['./custom-input.component.scss'],
// Step 1: copy paste this providers property
providers: [
{
provide: NG_VALUE_ACCESSOR,
useExisting: forwardRef(() => CustomInputComponent),
multi: true
}
]
})
// Step 2: Add "implements ControlValueAccessor"
export class CustomInputComponent implements ControlValueAccessor {
// Step 3: Copy paste this stuff here
onChange: any = () => {}
onTouch: any = () => {}
registerOnChange(fn: any): void {
this.onChange = fn;
}
registerOnTouched(fn: any): void {
this.onTouch = fn;
}
// Step 4: Define what should happen in this component, if something changes outside
input: string;
writeValue(input: string) {
this.input = input;
}
// Step 5: Handle what should happen on the outside, if something changes on the inside
// in this simple case, we've handled all of that in the .html
// a) we've bound to the local variable with ngModel
// b) we emit to the ouside by calling onChange on ngModelChange
}
// custom-input.component.html
<input type="text"
[(ngModel)]="input"
(ngModelChange)="onChange($event)"
(blur)="onTouch()">
// parent.component.html
<app-custom-input [formControl]="inputTwo"></app-custom-input>
// OR
<form [formGroup]="form" >
<app-custom-input formControlName="myFormControl"></app-custom-input>
</form>
Note that Control Value Accessors are NOT the right tool for nested form groups. For nested form groups you can simply use an @Input() subform
instead. Control Value Accessors are meant to wrap controls
, not groups
! See this example how to use an input for a nested form: https://stackblitz.com/edit/angular-nested-forms-input-2
The major difference is time-out, WCF Service has timed-out when there is no response, but web-service does not have this property.
In Chrome, there is the option is Console Settings (Developer Tools -> Console -> Settings [upper-right corner] ) named "Show timestamps" which is exactly what I needed.
I've just found it. No other dirty hacks needed that destroys placeholders and erases place in the code where the messages was logged from.
The "Show timestamps" setting has been moved to the Preferences pane of the "DevTools settings", found in the upper-right corner of the DevTools drawer:
dataGridView1.Sort(dataGridView1.Columns[0],ListSortDirection.Ascending);
Use DateTime::diff
(aka date_diff
):
$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);
Or:
$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);
You can then get the interval as a integer by calling $interval->days
.
Or you can just create your own MediaTypeFormatter
. I use this for text/html
. If you add text/plain
to it, it'll work for you too:
public class TextMediaTypeFormatter : MediaTypeFormatter
{
public TextMediaTypeFormatter()
{
SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
}
public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
{
return ReadFromStreamAsync(type, readStream, content, formatterLogger, CancellationToken.None);
}
public override async Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
{
using (var streamReader = new StreamReader(readStream))
{
return await streamReader.ReadToEndAsync();
}
}
public override bool CanReadType(Type type)
{
return type == typeof(string);
}
public override bool CanWriteType(Type type)
{
return false;
}
}
Finally you have to assign this to the HttpMethodContext.ResponseFormatter
property.
In addition to other answers, if you want to use the dash notition for style properties, you can also use:
document.getElementById("xyz").style["padding-top"] = "10px";
One workaround might be to write a simple batch file to run the program then shutdown the computer.
You can shut down from the command line -- so your script could be fairly simple:
c:\directory\myProgram.exe
C:\WINDOWS\system32\shutdown.exe -s -f -t 0
Know this is kind of old, but see many questions like this...
We use Chrome a lot in the classroom and it is a must to working with local files.
What we have been using is "Web Server for Chrome". You start it up, choose the folder wishing to work with and go to URL (like 127.0.0.1:port you chose)
It is a simple server and cannot use PHP but for simple work, might be your solution:
https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb
As a quick and very scoped solution:
Both Task.Result and Task.Wait won't allow to improving scalability when used with I/O, as they will cause the calling thread to stay blocked waiting for the I/O to end.
When you call .Result on an incomplete Task, the thread executing the method has to sit and wait for the task to complete, which blocks the thread from doing any other useful work in the meantime. This negates the benefit of the asynchronous nature of the task.
You should use setTimestamp instead, if you hardcode it:
$start_date = new DateTime();
$start_date->setTimestamp(1372622987);
in your case
$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);
Since Python 3.2, there are built-in functions for byte manipulation: https://docs.python.org/3.4/library/stdtypes.html#int.to_bytes.
By combining to_bytes and from_bytes, you get
def twos(val_str, bytes):
import sys
val = int(val_str, 2)
b = val.to_bytes(bytes, byteorder=sys.byteorder, signed=False)
return int.from_bytes(b, byteorder=sys.byteorder, signed=True)
Check:
twos('11111111', 1) # gives -1
twos('01111111', 1) # gives 127
For older versions of Python, travc's answer is good but it does not work for negative values if one would like to work with integers instead of strings. A twos' complement function for which f(f(val)) == val is true for each val is:
def twos_complement(val, nbits):
"""Compute the 2's complement of int value val"""
if val < 0:
val = (1 << nbits) + val
else:
if (val & (1 << (nbits - 1))) != 0:
# If sign bit is set.
# compute negative value.
val = val - (1 << nbits)
return val
A simple solution I used for an existing site in IE (using jQuery, but I can post back with eventListener
code if you really don't know JS that well) is the following:
if (jQuery.browser.msie) {
jQuery('#mySelect').focus(function() {
jQuery(this).width('auto');
}).bind('blur change', function() {
jQuery(this).width('100%');
});
};
Of course, use a variable (var cWidth = jQuery('#mySelect').width();
) to store the previous width, but this is all that was required for ours to work as you'd expect.
Just a reminder:
Remove orientation
from android:configChanges
attribute for the activity in your manifest xml
file if you defined it:
android:configChanges="orientation|screenLayout|screenSize"
The semicolon was throwing me off: I had JAVA_HOME
set to "C:\jdk1.6.0_26;" instead of "C:\jdk1.6.0_26". I removed the trailing semicolon after following Jon Skeet's suggestion to examine the ant.bat
file. This is part of that file:
if "%JAVA_HOME%" == "" goto noJavaHome
if not exist "%JAVA_HOME%\bin\java.exe" goto noJavaHome
So the semi-colon wasn't being trimmed off the end, causing this to fail to find the file, therefore defaulting to "C:\Java\jre6" or something like that.
The confusing part is that the HowtoBuild page states to use the semi-colon, but that seems to break it.
This might not really answer the question, but just in case someone just need to quickly send a string value to a function that require a NSArray parameter.
NSArray *data = @[@"The String Value"];
if you need to send more than just 1 string value, you could also use
NSArray *data = @[@"The String Value", @"Second String", @"Third etc"];
then you can send it to the function like below
theFunction(data);

You can use fetch optionally with await-try-catch
let photo = document.getElementById("image-file").files[0];
let formData = new FormData();
formData.append("photo", photo);
fetch('/upload/image', {method: "POST", body: formData});
async function SavePhoto(inp)
{
let user = { name:'john', age:34 };
let formData = new FormData();
let photo = inp.files[0];
formData.append("photo", photo);
formData.append("user", JSON.stringify(user));
const ctrl = new AbortController() // timeout
setTimeout(() => ctrl.abort(), 5000);
try {
let r = await fetch('/upload/image',
{method: "POST", body: formData, signal: ctrl.signal});
console.log('HTTP response code:',r.status);
} catch(e) {
console.log('Huston we have problem...:', e);
}
}

(in stack overflow snippets there is problem with error handling, however in <a href="https://jsfiddle.net/Lamik/b8ed5x3y/5/">jsfiddle version</a> for 404 errors 4xx/5xx are <a href="https://stackoverflow.com/a/33355142/860099">not throwing</a> at all but we can read response status which contains code)

Old school approach - xhr
let photo = document.getElementById("image-file").files[0]; // file from input
let req = new XMLHttpRequest();
let formData = new FormData();
formData.append("photo", photo);
req.open("POST", '/upload/image');
req.send(formData);
function SavePhoto(e)
{
let user = { name:'john', age:34 };
let xhr = new XMLHttpRequest();
let formData = new FormData();
let photo = e.files[0];
formData.append("user", JSON.stringify(user));
formData.append("photo", photo);
xhr.onreadystatechange = state => { console.log(xhr.status); } // err handling
xhr.timeout = 5000;
xhr.open("POST", '/upload/image');
xhr.send(formData);
}

(the stack overflow snippets, has some problem with error handling - the xhr.status is zero (instead of 404) which is similar to situation when we run script from file on <a href="https://stackoverflow.com/a/10173639/860099">local disc</a> - so I provide also js fiddle version which shows proper http error code <a href="https://jsfiddle.net/Lamik/k6jtq3uh/2/">here</a>)

SUMMARY
filename
formData parameter.Content-Type
to multipart/form-data
- this will be set automatically by browser./upload/image
you can use full address like http://.../upload/image
.multiple
attribute: <input multiple type=... />
, and attach all chosen files to formData in similar way (e.g. photo2=...files[2];
... formData.append("photo2", photo2);
)let user = {name:'john', age:34}
in this way: formData.append("user", JSON.stringify(user));
fetch
using AbortController
, for old approach by xhr.timeout= milisec
@Luch Filip's solution works well if you just want to rename the App package. In my case, I also want to rename the source package too, so as not to confuse things.
Only 2 steps are needed:
Click on your source folder e.g. com.company.example
> Shift + F6 (Refactor->Rename...) > Rename Package > enter your desired name.
Go to your AndroidManifest.xml, click on your package name > Shift + F6 (Refactor->Rename...) > enter same name as above.
Step 1 will automatically rename your R.java folder, and you can build straight away.
If an URL pattern starts with /
, then it's relative to the context root. The /Admin/*
URL pattern would only match pages on http://localhost:8080/EMS2/Admin/*
(assuming that /EMS2
is the context path), but you have them actually on http://localhost:8080/EMS2/faces/Html/Admin/*
, so your URL pattern never matches.
You need to prefix your URL patterns with /faces/Html
as well like so:
<url-pattern>/faces/Html/Admin/*</url-pattern>
You can alternatively also just reconfigure your web project structure/configuration so that you can get rid of the /faces/Html
path in the URLs so that you can just open the page by for example http://localhost:8080/EMS2/Admin/Upload.xhtml
.
Your filter mapping syntax is all fine. However, a simpler way to specify multiple URL patterns is to just use only one <filter-mapping>
with multiple <url-pattern>
entries:
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/faces/Html/Employee/*</url-pattern>
<url-pattern>/faces/Html/Admin/*</url-pattern>
<url-pattern>/faces/Html/Supervisor/*</url-pattern>
</filter-mapping>
Multiply the values by -1
There you go. All the highest numbers are now the lowest and vice versa.
Just remember that when you pop an element to multiply it with -1 in order to get the original value again.
Unicode arrows heads:
For ? and ? use ▲
and ▼
respectively if you cannot include Unicode characters directly (use UTF-8!).
Note that the font support for the smaller versions is not as good. Better to use the large versions in smaller font.
More Unicode arrows are at:
Lastly, these arrows are not ASCII, including ? and ?: they are Unicode.
As of 2020 language management become easy! All you have to do is:
Activity.applyOverrideConfiguration
Locale.setDefault
You must call those from the activity constructor since you can call to applyOverrideConfiguration
only once, and the system calls it pretty early.
And watch out from app-bundles, Google will split your APK by language resources automatically when using app-bundles. Check out the new API and the workaround here.
I created a helper class to help you with it. In my implementation G.app
is the application context. Also, I need to access resources from the app context so I use the Res
class for it, this one is optional, but I provide its code as well.
public BaseActivity(){
LanguageUtility.init(this);
}
public void changeLanguage(Local local){
// you must recreat your activity after you call this
LanguageUtillity.setDefaultLanguage(local, this);
}
public class LanguageUtility {
private static Configuration configuration;
public static void setDefaultLanguage(Locale locale, Context context) {
Locale.setDefault(locale);
context.getSharedPreferences("LocaleSettings", Context.MODE_PRIVATE)
.edit()
.putString("language", locale.getLanguage())
.putString("country", locale.getCountry())
.putString("variant", locale.getVariant())
.apply();
configuration = createConfiguration(context);
Res.updateContext();
}
/**
* Used to update your app context in case you cache it.
*/
public static Context createConfigurationContext(Context context) {
return context.createConfigurationContext(getConfiguration(context));
}
public static void init(Activity activity) {
activity.applyOverrideConfiguration(LanguageUtility.getConfiguration(G.app));
// you can't access sharedPrefferences from activity constructor
// with activity context, so I used the app context.
Locale.setDefault(getLocale(G.app));
}
@NotNull
private static Configuration getConfiguration(Context context) {
if (configuration == null) {
configuration = createConfiguration(context);
}
return configuration;
}
@NotNull
private static Configuration createConfiguration(Context context) {
Locale locale = getLocale(context);
Configuration configuration = new Configuration();
configuration.setLocale(locale);
LanguageUtility.configuration = configuration;
return configuration;
}
@NotNull
private static Locale getLocale(Context context) {
Locale aDefault = Locale.getDefault();
SharedPreferences preferences =
context.getSharedPreferences("LocaleSettings", Context.MODE_PRIVATE);
String language = preferences.getString("language", aDefault.getLanguage());
String country = preferences.getString("country", aDefault.getCountry());
String variant = preferences.getString("variant", aDefault.getVariant());
return new Locale(language, country, variant);
}
}
An optional Res class.
public class Res {
@SuppressLint("StaticFieldLeak")
public static Context appLocalContext = LanguageUtility.createConfigurationContext(G.app);
public static void updateContext() {
appLocalContext = LanguageUtility.createConfigurationContext(G.app);
}
public static String getString(@StringRes int id, Object... formatArgs) {
return appLocalContext.getResources().getString(id, formatArgs);
}
public static int getColor(@ColorRes int id) {
return G.app.getColor(id);
}
}
The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.
import numpy as np
names = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 , 0.5678 , 0.9123 ])
ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats
np.savetxt('test.txt', ab, fmt="%10s %10.3f")
Update: This example also works properly in Python 3 by using the 'U6'
Unicode string dtype, when creating the ab
structured array, instead of the 'S6'
byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1'
in Python 3.
This hybrid solution worked for me, both on single and dual screen setup
function popupCenter (url, title, w, h) {
// Fixes dual-screen position Most browsers Firefox
const dualScreenLeft = window.screenLeft !== undefined ? window.screenLeft : window.screenX;
const dualScreenTop = window.screenTop !== undefined ? window.screenTop : window.screenY;
const left = (window.screen.width/2)-(w/2) + dualScreenLeft;
const top = (window.screen.height/2)-(h/2) + dualScreenTop;
return window.open(url, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+top+', left='+left);
}
<script type="text/javascript">_x000D_
$(window).bind("load", function() { _x000D_
_x000D_
// your javascript event here_x000D_
_x000D_
});_x000D_
</script>

I know the question is about getting the day of week as string (e.g. the short name), but for anybody who is looking for the numeric day of week (as I was), you can use the new "u" format string, supported since Java 7. For example:
new SimpleDateFormat("u").format(new Date());
returns today's day-of-week index, namely: 1 = Monday, 2 = Tuesday, ..., 7 = Sunday.
An alternative: git rev-list master | grep "$(git rev-list HEAD)" | head -1

This is due to a bug in Webkit.
You can work around the Webkit bug using createEvent('Event')
rather than createEvent('KeyboardEvent')
, and then assigning the keyCode
property. See this answer and this example.
Add the s
modifier to your regex to cause .
to match newlines:
$string =~ /(START)(.+?)(END)/s;
