The idea is to insert special SVG with fallback style.
More details and testing process you can find in my blog.
For my case I need to radius begin and end of path
:
With stroke-linecap: round;
I change it to what I want:
Go to you MainActivity.java
and below this code
-> NavigationView navigationView = findViewById(R.id.nav_view);
Add single line of code -> navigationView.setItemIconTintList(null);
i.e. the last line of my code
I hope this might solve your problem.
public class MainActivity extends AppCompatActivity {
private AppBarConfiguration mAppBarConfiguration;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setItemIconTintList(null);
If any one's trying to fetch all headers that were passed then just simply use:
dict(request.headers)
it gives you all the headers in a dict from which you can actually do whatever ops you want to. In my use case I had to forward all headers to another API since the python API was a proxy
As serialization doesn't work generally (only when the order of properties matches: JSON.stringify({a:1,b:2}) !== JSON.stringify({b:2,a:1})
) you have to check the count of properties and compare each property as well:
const objectsEqual = (o1, o2) =>_x000D_
Object.keys(o1).length === Object.keys(o2).length _x000D_
&& Object.keys(o1).every(p => o1[p] === o2[p]);_x000D_
_x000D_
const obj1 = { name: 'John', age: 33};_x000D_
const obj2 = { age: 33, name: 'John' };_x000D_
const obj3 = { name: 'John', age: 45 };_x000D_
_x000D_
console.log(objectsEqual(obj1, obj2)); // true_x000D_
console.log(objectsEqual(obj1, obj3)); // false
_x000D_
If you need a deep comparison, you can call the function recursively:
const obj1 = { name: 'John', age: 33, info: { married: true, hobbies: ['sport', 'art'] } };_x000D_
const obj2 = { age: 33, name: 'John', info: { hobbies: ['sport', 'art'], married: true } };_x000D_
const obj3 = { name: 'John', age: 33 };_x000D_
_x000D_
const objectsEqual = (o1, o2) => _x000D_
typeof o1 === 'object' && Object.keys(o1).length > 0 _x000D_
? Object.keys(o1).length === Object.keys(o2).length _x000D_
&& Object.keys(o1).every(p => objectsEqual(o1[p], o2[p]))_x000D_
: o1 === o2;_x000D_
_x000D_
console.log(objectsEqual(obj1, obj2)); // true_x000D_
console.log(objectsEqual(obj1, obj3)); // false
_x000D_
Then it's easy to use this function to compare objects in arrays:
const arr1 = [obj1, obj1];
const arr2 = [obj1, obj2];
const arr3 = [obj1, obj3];
const arraysEqual = (a1, a2) =>
a1.length === a2.length && a1.every((o, idx) => objectsEqual(o, a2[idx]));
console.log(arraysEqual(arr1, arr2)); // true
console.log(arraysEqual(arr1, arr3)); // false
I have had good experiences with Rational Purify. I have also heard nice things about Valgrind
Yes, use source or the short form which is just .

. other_script.sh
In python 3.5+ inheritance looks predictable and very nice for me. Please looks at this code:
class Base(object):
def foo(self):
print(" Base(): entering")
print(" Base(): exiting")
class First(Base):
def foo(self):
print(" First(): entering Will call Second now")
super().foo()
print(" First(): exiting")
class Second(Base):
def foo(self):
print(" Second(): entering")
super().foo()
print(" Second(): exiting")
class Third(First, Second):
def foo(self):
print(" Third(): entering")
super().foo()
print(" Third(): exiting")
class Fourth(Third):
def foo(self):
print("Fourth(): entering")
super().foo()
print("Fourth(): exiting")
Fourth().foo()
print(Fourth.__mro__)
Outputs:
Fourth(): entering
Third(): entering
First(): entering Will call Second now
Second(): entering
Base(): entering
Base(): exiting
Second(): exiting
First(): exiting
Third(): exiting
Fourth(): exiting
(<class '__main__.Fourth'>, <class '__main__.Third'>, <class '__main__.First'>, <class '__main__.Second'>, <class '__main__.Base'>, <class 'object'>)
As you can see, it calls foo exactly ONE time for each inherited chain in the same order as it was inherited. You can get that order by calling .mro :
Fourth -> Third -> First -> Second -> Base -> object
I'm not positive what you're asking, but if you're looking for an example of when one would want to use a null key, I use them often in maps to represent the default case (i.e. the value that should be used if a given key isn't present):
Map<A, B> foo;
A search;
B val = foo.containsKey(search) ? foo.get(search) : foo.get(null);
HashMap
handles null keys specially (since it can't call .hashCode()
on a null object), but null values aren't anything special, they're stored in the map like anything else
When is the
finalize()
method called in Java?
The finalize method will be called after the GC detects that the object is no longer reachable, and before it actually reclaims the memory used by the object.
If an object never becomes unreachable, finalize()
will never be called on it.
If the GC doesn't run then finalize()
may never be called. (Normally, the GC only runs when the JVM decides that there is likely to enough garbage to make it worthwhile.)
It may take more than one GC cycle before the GC determines that a specific object is unreachable. (Java GCs are typically "generational" collectors ...)
Once the GC detects an object is unreachable and finalizable, it is places on a finalization queue. Finalization typically occurs asynchronously with the normal GC.
(The JVM spec actually allows a JVM to never run finalizers ... provided that it doesn't reclaim the space used by the objects. A JVM that was implemented this way would be crippled / useless, but it this behavior is "allowed".)
The upshot is that it is unwise to rely on finalization to do things that have to be done in a definite time-frame. It is "best practice" not to use them at all. There should be a better (i.e. more reliable) way to do whatever it is you are trying to do in the finalize()
method.
The only legitimate use for finalization is to clean up resources associated with objects that have been lost by application code. Even then, you should try to write the application code so that it doesn't lose the objects in the first place. (For example, use Java 7+ try-with-resources to ensure that close()
is always called ...)
I created a test class which writes into a file when the finalize() method is called by overriding it. It is not executed. Can anybody tell me the reason why it is not executing?
It is hard to say, but there are a few possibilities:
I think your problem is when displaying the decimal, not the contents of it.
If you try
string value = "1200.00";
decimal d = decimal.Parse(s);
string s = d.ToString();
s
will contain the string "1200"
.
However if you change your code to this
string value = "1200.00";
decimal d = decimal.Parse(s);
string s = d.ToString("0.00");
s
will contain the string "1200.00"
as you want it to do.
EDIT
Seems I'm braindead early in the morning today. I added the Parse
statements now. However even my first code will output "1200.00", even if I expected it to output "1200". Seems like I'm learning something each day, and in this case obviously something that is quite basic.
So disregard this a an proper answer. We will probably need more code to identify your problem in this case.
If you're using create-react-app, you can simply add a .env
file containing
NODE_PATH=src/

Normally in Visual Studio 2015 you should create the dll project as a C++ -> CLR project from Visual Studio's templates, but you can technically enable it after the fact:
The critical property is called Common Language Runtime Support
set in your project's configuration. It's found under Configuration Properties > General > Common Language Runtime Support
.
When doing this, VS will probably not update the 'Target .NET Framework' option (like it should). You can manually add this by unloading your project, editing the your_project.xxproj file, and adding/updating the Target .NET framework Version
XML tag.
For a sample, I suggest creating a new solution as a C++ CLR project and examining the XML there, perhaps even diffing it to make sure there's nothing very important that's out of the ordinary.
Press the Windows Key and type Windows Features, select the first entry Turn Windows Features On or Off.
Make sure the box next to IIS is checked. You good to go.
For Bootstrap 4
Some of the previous answers are not working for Bootstrap 4. To reduce the size of the navigation bar in this version, I suggest eliminating the padding like this.
.navbar { padding-top: 0.25rem; padding-bottom: 0.25rem; }
You could try with other styles too.
The styles I found that define the total height of the navigation bar are:
padding-top
and padding-bottom
are set to 0.5rem for .navbar
.padding-top
and padding-bottom
are set to 0.5rem for .navbar-text
.line-height
of 1.5rem inherited from the body
.Thus, in total the navigation bar is 3.5 times the root font size.
In my case, which I was using big font sizes; I redefined the ".navbar" class in my CSS file like this:
.navbar {
padding-top: 0.25rem; /* 0px does not look good on small screens */
padding-bottom: 0.25rem;
font-size: smaller; /* Just because I am using big size font */
line-height: 1em;
}
Final comment, avoid using absolute values when playing with the previous styles. Use the units rem
or em
instead.
They follow the same naming rules as variable names. Therefore they should not contain spaces.
Also what you are suggesting would be very bad practice anyway.
$disk = Get-WmiObject Win32_LogicalDisk -ComputerName remotecomputer -Filter "DeviceID='C:'" |
Select-Object Size,FreeSpace
$disk.Size
$disk.FreeSpace
To extract the values only and assign them to a variable:
$disk = Get-WmiObject Win32_LogicalDisk -ComputerName remotecomputer -Filter "DeviceID='C:'" |
Foreach-Object {$_.Size,$_.FreeSpace}
The main difference is GIF is patented and a bit more widely supported. PNG is an open specification and alpha transparency is not supported in IE6. Support was improved in IE7, but not completely fixed.
As far as file sizes go, GIF has a smaller default color pallet, so they tend to be smaller file sizes at first glance. PNG files have a larger default pallet, however you can shrink their color pallet so that, when you do, they result in a smaller file size than GIF. The issue again is that this feature isn't as supported in Internet Explorer.
Also, because PNGs can support alpha transparency, they're the only option if you want a variation of transparency other than binary transparency.
If your PHP server allows url fopen wrappers then the simplest way is:
$html = file_get_contents('https://stackoverflow.com/questions/ask');
If you need more control then you should look at the cURL functions:
$c = curl_init('https://stackoverflow.com/questions/ask');
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
//curl_setopt(... other options you want...)
$html = curl_exec($c);
if (curl_error($c))
die(curl_error($c));
// Get the status code
$status = curl_getinfo($c, CURLINFO_HTTP_CODE);
curl_close($c);
For a list of full path names I prefer this version to the other solutions here:
def listdirs(dir):
return [os.path.join(os.path.join(dir, x)) for x in os.listdir(dir)
if os.path.isdir(os.path.join(dir, x))]
If your console supports ANSI colour codes (e.g. ConEmu, Clink or ANSICON) you can do this:
SET GRAY=%ESC%[0m
SET RED=%ESC%[1;31m
SET GREEN=%ESC%[1;32m
SET ORANGE=%ESC%[0;33m
SET BLUE=%ESC%[0;34m
SET MAGENTA=%ESC%[0;35m
SET CYAN=%ESC%[1;36m
SET WHITE=%ESC%[1;37m
where ESC variable contains ASCII character 27.
I found a way to populate the ESC variable here: http://www.dostips.com/forum/viewtopic.php?p=6827#p6827
and using tasklist
it's possible to test what DLLs are loaded into a process.
The following script gets the process ID of the cmd.exe that the script is running in. Checks if it has a dll that will add ANSI support injected, and then sets colour variables to contain escape sequences or be empty depending on whether colour is supported or not.

This will use the file from the branch of choice.
I like this because posh-git
autocomplete works great with this. It also removes any ambiguity as to which branch is remote and which is local.

The approach I use is to start the "Visual Studio Command Prompt" which can be found in the Start menu. E.g. my visual studio 2010 Express install has a shortcute Visual Studio Command Prompt (2010)
at Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools
.
This shortcut prepares an environment by calling a script vcvarsall.bat
where the compiler, linker, etc. are setup from the right Visual Studio installation.
Alternatively, if you already have a prompt open, you can prepare the environment by calling a similar script:
:: For x86 (using the VS100COMNTOOLS env-var)
call "%VS100COMNTOOLS%"\..\..\VC\bin\vcvars32.bat
or
:: For amd64 (using the full path)
call C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat
Your output (with the '$' prompt) suggests that you are attempting to run CMake from a MSys shell. In that case it might be better to run CMake for MSys or MinGW, by explicitly specifying a makefile generator:
cmake -G"MSYS Makefiles"
cmake -G"MinGW Makefiles"
Run cmake --help
to get a list of all possible generators.
You can use JQuery(jquery.validate.js) to make it work easily.
$.validator.format("My name is {0}, I'm {1} years old",["Bob","23"]);
Or if you want to use just that feature you can define that function and just use it like
function format(source, params) {
$.each(params,function (i, n) {
source = source.replace(new RegExp("\\{" + i + "\\}", "g"), n);
})
return source;
}
alert(format("{0} is a {1}", ["Michael", "Guy"]));

You say you don't necessarily know that 'key2' is in position [1]. Well, it's not. Position 1 would be occupied by myHash[1].
You're abusing JavaScript arrays, which (like functions) allow key/value hashes. Even though JavaScript allows it, it does not give you facilities to deal with it, as a language designed for associative arrays would. JavaScript's array methods work with the numbered properties only.
The first thing you should do is switch to objects rather than arrays. You don't have a good reason to use an array here rather than an object, so don't do it. If you want to use an array, just number the elements and give up on the idea of hashes. The intent of an array is to hold information which can be indexed into numerically.
You can, of course, put a hash (object) into an array if you like.
myhash[1]={"key1","brightOrangeMonkey"};
If you are using an MVC framework with routes and actions:

In my case, I was trying to create a runnable jar on Windows OS with chrome browser and want to run the same on headless mode in unix box with CentOs on it. And I was pointing my binary to a driver that I have downloaded and packaged with my suite. For me, this issue continue to occur irrespective of adding the below:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("window-size=1024,768"); // Bypass OS security model
options.addArguments("--log-level=3"); // set log level
options.addArguments("--silent");//
options.setCapability("chrome.verbose", false); //disable logging
driver = new ChromeDriver(options);
Solution that I've tried and worked for me is, download the chrome and its tools on the host VM/Unix box, install and point the binary to this in the automation suite and bingo! It works :)
Download command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install command:
sudo yum install -y ./google-chrome-stable_current_*.rpm
Update suite with below binary path of google-chrome:
options.setBinary("/opt/google/chrome/google-chrome");
And.. it works!
In my case that happened when uninstalling AspNet 5 RC1 Update 1 to update it for .Net Core 1.0 RC2. so I installed Visual Studio 2015 update 2, selected Microsoft Web Developer tools and everything went back to normal.
Yes this is possible, however not convenient as Jens said. Using Next generation load balancers like Alteon, which Uses a proprietary protocol called DSSP(Distributed site state Protocol) which performs regular site checks to make sure that the service is available both Locally or Globally i.e different geographical areas. You need to however in your Master DNS to delegate the URL or Service to the device by configuring it as an Authoritative Name Server for that IP or Service. By doing this, the device answers DNS queries where it will resolve the IP that has a service by Round-Robin or is not congested according to how you have chosen from several metrics.

You can use CSS3 transition

Is your logic not round the wrong way in that example, you have it hiding when the screen is bigger than 1024. Reverse the cases, make the none
in to a block
and vice versa.
Yes, the Map interface will allow you to store Arrays as values. Here's a very simple example:
int[] val = {1, 2, 3};
Map<String, int[]> map = new HashMap<String, int[]>();
map.put("KEY1", val);
Also, depending on your use case you may want to look at the Multimap support offered by guava.
You should connect to the place that your actual application needs. Otherwise you're testing whether you have a connection to somewhere irrelevant (Google in this case).
In particular, if you're trying to talk to a web service, and if you're in control of the web service, it would be a good idea to have some sort of cheap "get the status" web method. That way you have a much better idea of whether your "real" call is likely to work.
In other cases, just opening a connection to a port that should be open may be enough - or sending a ping. InetAddress.isReachable
may well be an appropriate API for your needs here.
Blaze meter has a chrome extension for recording sessions and exporting them to JMeter (currently requires login). You also have the option of paying them money to run it on their cluster of JMeter servers (their pricing seems much better than LoadImpact which I've just stopped using):
I don't have any association with them, I just like the look of their service, although I haven't used the paid version yet.
Use String#next
as the counter.
>> n = "000"
>> 3.times { puts "file_#{n.next!}" }
file_001
file_002
file_003
next
is relatively 'clever', meaning you can even go for
>> n = "file_000"
>> 3.times { puts n.next! }
file_001
file_002
file_003
use the pow
function (it takes float
s/double
s though).
man pow
:
#include <math.h>
double pow(double x, double y);
float powf(float x, float y);
long double powl(long double x, long double y);
EDIT: For the special case of positive integer powers of 2
, you can use bit shifting: (1 << x)
will equal 2
to the power x
. There are some potential gotchas with this, but generally, it would be correct.
[a-zA-Z]
should do that just fine.
You can reference the cheat sheet.
Let's look at both ways:
(function(){
var i2 = i;
setTimeout(function(){
console.log(i2);
}, 1000)
})();
Declares and immediately executes an anonymous function that runs setTimeout()
within its own context. The current value of i
is preserved by making a copy into i2
first; it works because of the immediate execution.
setTimeout((function(i2){
return function() {
console.log(i2);
}
})(i), 1000);
Declares an execution context for the inner function whereby the current value of i
is preserved into i2
; this approach also uses immediate execution to preserve the value.
Important
It should be mentioned that the run semantics are NOT the same between both approaches; your inner function gets passed to setTimeout()
whereas his inner function calls setTimeout()
itself.
Wrapping both codes inside another setTimeout()
doesn't prove that only the second approach uses closures, there's just not the same thing to begin with.
Conclusion
Both methods use closures, so it comes down to personal taste; the second approach is easier to "move" around or generalize.
Just add the font awesome class like this:
class="fa fa-plus-circle fa-3x"
(You can increase the size as per 5x, 7x, 9x..)
You can also add custom CSS.
--reverse is also helpful since you want the first commit that made the change:
git log --all -p --reverse --source -S 'needle'
This way older commits will appear first.
That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.
I also faced the same problem but I resolved the issue by starting the TNS listener in control panel -> administrative tools -> services ->oracle TNS listener start.I am using windows Xp and Toad to connect to Oracle.
First, You have to install the Android Studio and Xcode to create phone emulator.
In VSCode you can use the Android IOS Emulator plugin to set the path of emulator to run.
You can use Environment.CurrentDirectory
to get the current directory, and FileSystemInfo.FullPath
to get the full path to any location. So, fully qualify both the current directory and the file in question, and then check whether the full file name starts with the directory name - if it does, just take the appropriate substring based on the directory name's length.
Here's some sample code:
using System;
using System.IO;
class Program
{
public static void Main(string[] args)
{
string currentDir = Environment.CurrentDirectory;
DirectoryInfo directory = new DirectoryInfo(currentDir);
FileInfo file = new FileInfo(args[0]);
string fullDirectory = directory.FullName;
string fullFile = file.FullName;
if (!fullFile.StartsWith(fullDirectory))
{
Console.WriteLine("Unable to make relative path");
}
else
{
// The +1 is to avoid the directory separator
Console.WriteLine("Relative path: {0}",
fullFile.Substring(fullDirectory.Length+1));
}
}
}
I'm not saying it's the most robust thing in the world (symlinks could probably confuse it) but it's probably okay if this is just a tool you'll be using occasionally.
I think the best ranking is
1.node-schedule
2.later
3.crontab
and the sample of node-schedule is below:
var schedule = require("node-schedule");
var rule = new schedule.RecurrenceRule();
//rule.minute = 40;
rule.second = 10;
var jj = schedule.scheduleJob(rule, function(){
console.log("execute jj");
});
Maybe you can find the answer from node modules.

var first = document.getElementById("textbox1").value;_x000D_

There should be three pages here:
I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.
I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.
You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST
submission on step 1 (and 2 if applicable).
!members.find()
I think now the best way to solve this issue is code above. It works since Groovy 1.8.1 http://docs.groovy-lang.org/docs/next/html/groovy-jdk/java/util/Collection.html#find(). Examples:
def lst1 = []
assert !lst1.find()
def lst2 = [null]
assert !lst2.find()
def lst3 = [null,2,null]
assert lst3.find()
def lst4 = [null,null,null]
assert !lst4.find()
def lst5 = [null, 0, 0.0, false, '', [], 42, 43]
assert lst5.find() == 42
def lst6 = null;
assert !lst6.find()
As of April 2018, Chrome (along with several other major browsers) now require the muted
attribute too.
Therefore, you should use
<video width="320" height="240" autoplay loop muted>
<source src="movie.mp4" type="video/mp4" />
</video>
The problem I was having, which I think is similar to this, is that master was too far ahead of my branch point for the history to be useful. (Navigating to the branch point would take too long.)
After some trial and error, this gave me roughly what I wanted:
git log --graph --decorate --oneline --all ^master^!
def import_class(cl):
d = cl.rfind(".")
classname = cl[d+1:len(cl)]
m = __import__(cl[0:d], globals(), locals(), [classname])
return getattr(m, classname)
You might actually look into the internationally standardized format E.164, recommended by Twilio for example (who have a service and an API for sending SMS or phone-calls via REST requests).
This is likely to be the most universal way to store phone numbers, in particular if you have international numbers work with.
You can use phonenumber_field
library. It is port of Google's libphonenumber library, which powers Android's phone number handling
https://github.com/stefanfoulis/django-phonenumber-field
In model:
from phonenumber_field.modelfields import PhoneNumberField
class Client(models.Model, Importable):
phone = PhoneNumberField(null=False, blank=False, unique=True)
In form:
from phonenumber_field.formfields import PhoneNumberField
class ClientForm(forms.Form):
phone = PhoneNumberField()
Get phone as string from object field:
client.phone.as_e164
Normolize phone string (for tests and other staff):
from phonenumber_field.phonenumber import PhoneNumber
phone = PhoneNumber.from_string(phone_number=raw_phone, region='RU').as_e164
One note for your model: E.164 numbers have a max character length of 15.
To validate, you can employ some combination of formatting and then attempting to contact the number immediately to verify.
I believe I used something like the following on my django project:
class ReceiverForm(forms.ModelForm):
phone_number = forms.RegexField(regex=r'^\+?1?\d{9,15}$',
error_message = ("Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed."))
EDIT
It appears that this post has been useful to some folks, and it seems worth it to integrate the comment below into a more full-fledged answer. As per jpotter6, you can do something like the following on your models as well:
models.py:
from django.core.validators import RegexValidator
class PhoneModel(models.Model):
...
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], max_length=17, blank=True) # validators should be a list
Starting with Java 11, you can use the repeat(...) method:
"0".repeat(Integer.numberOfLeadingZeros(i) - 16) + Integer.toBinaryString(i)
Or, if you need 32-bit representation of any integer:
"0".repeat(Integer.numberOfLeadingZeros(i != 0 ? i : 1)) + Integer.toBinaryString(i)
The main method of the runtime engine looks something like int main(int argc, char *argv[])
, where argc is a count of the number of arguments and argv is an array of pointers to each. The runtime engine converts this into a form that is more natural to c#.
Prior to that main method being called, everything is in assembly language. It has access to the command line arguments (because the operating system makes that available to every process that starts), but that assembly language needs to convert a single string of the full command line into multiple substrings (using whitespace to separate them) before it's ready to pass them into main().
public abstract class SingleFragmentActivity extends Activity {
public static final String FRAGMENT_TAG = "single";
private Fragment fragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null) {
fragment = onCreateFragment();
getFragmentManager().beginTransaction()
.add(android.R.id.content, fragment, FRAGMENT_TAG)
.commit();
} else {
fragment = getFragmentManager().findFragmentByTag(FRAGMENT_TAG);
}
}
public abstract Fragment onCreateFragment();
public Fragment getFragment() {
return fragment;
}
}
use
public class ViewCatalogItemActivity extends SingleFragmentActivity {
@Override
public Fragment onCreateFragment() {
return new FragmentWorkShops();
}
}
As in Internet Explorer, the javascript method "includes" doesn't support which is leading to the error as below
dijit.form.FilteringSelect TypeError: Object doesn't support property or method 'includes'
So I have changed the JavaScript string method from "includes" to "indexOf" as below
//str1 doesn't match str2 w.r.t index, so it will try to add object
var str1="acd", str2="b";
if(str1.indexOf(str2) == -1)
{
alert("add object");
}
else
{
alert("object not added");
}
You can use these commands :
<? system('whoami');?>
or
<? passthru('whoami');?>
or
<? print exec('whoami');?>
or
<? print shell_exec('whoami');?>
Be aware, the get_current_user()
returns the name of the owner of the current PHP script !
There is the beforeShowDay
option, which takes a function to be called for each date, returning true if the date is allowed or false if it is not. From the docs:
beforeShowDay
The function takes a date as a parameter and must return an array with [0] equal to true/false indicating whether or not this date is selectable and 1 equal to a CSS class name(s) or '' for the default presentation. It is called for each day in the datepicker before is it displayed.
Display some national holidays in the datepicker.
$(".selector").datepicker({ beforeShowDay: nationalDays})
natDays = [
[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'],
[4, 27, 'za'], [5, 25, 'ar'], [6, 6, 'se'],
[7, 4, 'us'], [8, 17, 'id'], [9, 7, 'br'],
[10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']
];
function nationalDays(date) {
for (i = 0; i < natDays.length; i++) {
if (date.getMonth() == natDays[i][0] - 1
&& date.getDate() == natDays[i][1]) {
return [false, natDays[i][2] + '_day'];
}
}
return [true, ''];
}
One built in function exists, called noWeekends, that prevents the selection of weekend days.
$(".selector").datepicker({ beforeShowDay: $.datepicker.noWeekends })
To combine the two, you could do something like (assuming the nationalDays
function from above):
$(".selector").datepicker({ beforeShowDay: noWeekendsOrHolidays})
function noWeekendsOrHolidays(date) {
var noWeekend = $.datepicker.noWeekends(date);
if (noWeekend[0]) {
return nationalDays(date);
} else {
return noWeekend;
}
}
Update: Note that as of jQuery UI 1.8.19, the beforeShowDay option also accepts an optional third paremeter, a popup tooltip
I actually had an easy workaround on this one in which I nearly scratch my head on how to make it work. hahah!
Well, first I downloaded Bootstrap (the compiled css and js version).
Then I pasted all the bootstrap css files to the app/assets/stylesheets/
.
And then I pasted all the bootstrap js files to the app/assets/javascripts/
.
I reloaded the page and wallah! I just added bootstrap in my RoR!
try this:
import time
import os
n = 0
for x in range(10): #enter your value here
print(n)
time.sleep(1) #to wait a second
os.system('cls') #to clear previous number
#use ('clear') if you are using linux or mac!
n = n + 1

You need to use an undocumented trick with Excel's LINEST
function:
=LINEST(known_y's, [known_x's], [const], [stats])
A regular linear regression is calculated (with your data) as:
=LINEST(B2:B21,A2:A21)
which returns a single value, the linear slope (m
) according to the formula:
which for your data:
is:
You can also use Excel to calculate a regression with a formula that uses an exponent for x
different from 1
, e.g. x1.2:
using the formula:
=LINEST(B2:B21, A2:A21^1.2)
which for you data:
is:
Excel's LINEST
function can also calculate multiple regressions, with different exponents on x
at the same time, e.g.:
=LINEST(B2:B21,A2:A21^{1,2})
Note: if locale is set to European (decimal symbol ","), then comma should be replaced by semicolon and backslash, i.e.
=LINEST(B2:B21;A2:A21^{1\2})
Now Excel will calculate regressions using both x1 and x2 at the same time:
The impossibly tricky part there's no obvious way to see the other regression values. In order to do that you need to:
select the cell that contains your formula:
extend the selection the left 2 spaces (you need the select to be at least 3 cells wide):
press F2
press Ctrl+Shift+Enter
You will now see your 3 regression constants:
y = -0.01777539x^2 + 6.864151123x + -591.3531443
I had a function that I wanted to perform a regression using some exponent:
y = m×xk + b
But I didn't know the exponent. So I changed the LINEST
function to use a cell reference instead:
=LINEST(B2:B21,A2:A21^F3, true, true)
With Excel then outputting full stats (the 4th paramter to LINEST
):
I tell the Solver to maximize R2:
And it can figure out the best exponent. Which for you data:
is:
The backslash in C is used to escape characters in strings. Strings would not recognize %
as a special character, and therefore no escape would be necessary. printf
is another matter: use %%
to print one %

dksnap
(https://github.com/kelda/dksnap) automates the process of running pg_dumpall
and loading the dump via /docker-entrypoint-initdb.d
.
It shows you a list of running containers, and you pick which one you want to backup. The resulting artifact is a regular Docker image, so you can then docker run
it, or share it by pushing it to a Docker registry.

I am not experienced with Eclipse or Maven so the other answers seemed a bit over complicated.
The following simpler set of steps worked for me:

onActivityCreated()
is now deprecated as Fragments Version 1.3.0-alpha02
The onActivityCreated() method is now deprecated. Code touching the fragment's view should be done in onViewCreated() (which is called immediately before onActivityCreated()) and other initialization code should be in onCreate(). To receive a callback specifically when the activity's onCreate() is complete, a LifeCycleObserver should be registered on the activity's Lifecycle in onAttach(), and removed once the onCreate() callback is received.

The difference between a non-lateral
and a lateral
join lies in whether you can look to the left hand table's row. For example:
select *
from table1 t1
cross join lateral
(
select *
from t2
where t1.col1 = t2.col1 -- Only allowed because of lateral
) sub
This "outward looking" means that the subquery has to be evaluated more than once. After all, t1.col1
can assume many values.
By contrast, the subquery after a non-lateral
join can be evaluated once:
select *
from table1 t1
cross join
(
select *
from t2
where t2.col1 = 42 -- No reference to outer query
) sub
As is required without lateral
, the inner query does not depend in any way on the outer query. A lateral
query is an example of a correlated
query, because of its relation with rows outside the query itself.

The question is little unclear because the title of the question is asking about string and set conversion but then the question at the end asks how do I serialize ? !
let me refresh the concept of Serialization is the process of encoding an object, including the objects it refers to, as a stream of byte data.
If interested to serialize you can use:
json.dumps -> serialize
json.loads -> deserialize
If your question is more about how to convert set to string and string to set then use below code (it's tested in Python 3)
String to Set
set('abca')
Set to String
''.join(some_var_set)
example:
def test():
some_var_set=set('abca')
print("here is the set:",some_var_set,type(some_var_set))
some_var_string=''.join(some_var_set)
print("here is the string:",some_var_string,type(some_var_string))
test()
I ran into this issue as well and found this post. Ultimately none of these answers solved my problem, instead I had to put in a rewrite rule to strip out the location /rt
as the backend my developers made was not expecting any additional paths:
+-(william@wkstn18)--(Thu, 05 Nov 20)-+
+-(~)--(16:13)->wscat -c ws://WebsocketServerHostname/rt
error: Unexpected server response: 502
Testing with wscat repeatedly gave a 502 response. Nginx error logs provided the same upstream error as above, but notice the upstream string shows the GET Request is attempting to access localhost:12775/rt and not localhost:12775:
2020/11/05 22:13:32 [error] 10175#10175: *7 upstream prematurely closed

HTTP/1.1", upstream: "http://127.0.0.1:12775/rt/socket.io/?transport=websocket",
host: "WebsocketServerHostname"
Since the devs had not coded their websocket (listening on 12775) to expect /rt/socket.io but instead just /socket.io/ (NOTE: /socket.io/ appears to just be a way to specify websocket transport discussed here). Because of this, rather than ask them to rewrite their socket code I just put in a rewrite rule to translate WebsocketServerHostname/rt to WebsocketServerHostname:12775 as below:
upstream websocket-rt {
ip_hash;
server 127.0.0.1:12775;
}
server {
listen 80;
server_name WebsocketServerHostname;
location /rt {
proxy_http_version 1.1;
#rewrite /rt/ out of all requests and proxy_pass to 12775
rewrite /rt/(.*) /$1 break;

proxy_pass http://websocket-rt;

}
CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.
I used Sorin Comanescu's solution, but hit a problem when trying to get the selected value. My combobox was a toolstrip combobox. I used the "combobox" property, which exposes a normal combobox.
I had a
Dictionary<Control, string> controls = new Dictionary<Control, string>();
Binding code (Sorin Comanescu's solution - worked like a charm):
controls.Add(pictureBox1, "Image");
controls.Add(dgvText, "Text");
cbFocusedControl.ComboBox.DataSource = new BindingSource(controls, null);
cbFocusedControl.ComboBox.ValueMember = "Key";
cbFocusedControl.ComboBox.DisplayMember = "Value";
The problem was that when I tried to get the selected value, I didn't realize how to retrieve it. After several attempts I got this:
var control = ((KeyValuePair<Control, string>) cbFocusedControl.ComboBox.SelectedItem).Key
Hope it helps someone else!
@Schildmeijer is largely right, however port 7001 is still used when using TLS Encrypted Internode communication
So my complete list would be for current versions of Cassandra:
The recommended approach in this case is to sort the data in the database, adding an ORDER BY
at the end of the query that fetches the results, something like this:
SELECT temperature FROM temperatures ORDER BY temperature ASC; -- ascending order
SELECT temperature FROM temperatures ORDER BY temperature DESC; -- descending order
If for some reason that is not an option, you can change the sorting order like this in Python:
templist = [25, 50, 100, 150, 200, 250, 300, 33]
sorted(templist, key=int) # ascending order
> [25, 33, 50, 100, 150, 200, 250, 300]
sorted(templist, key=int, reverse=True) # descending order
> [300, 250, 200, 150, 100, 50, 33, 25]
As has been pointed in the comments, the int
key (or float
if values with decimals are being stored) is required for correctly sorting the data if the data received is of type string
, but it'd be very strange to store temperature values as strings, if that is the case, go back and fix the problem at the root, and make sure that the temperatures being stored are numbers.
Of course, Object.keys()
is the best way to get an Object's keys. If it's not available in your environment, it can be trivially shimmed using code such as in your example (except you'd need to take into account your loop will iterate over all properties up the prototype chain, unlike Object.keys()
's behaviour).
However, your example code...
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [];
for (var key in foo) {
keys.push(key);
}
...could be modified. You can do the assignment right in the variable part.
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [], i = 0;
for (keys[i++] in foo) {}
Of course, this behaviour is different to what Object.keys()
actually does (jsFiddle). You could simply use the shim on the MDN documentation.
For defining a long string inside a dict, keeping the newlines but omitting the spaces, I ended up defining the string in a constant like this:
LONG_STRING = \
"""
This is a long sting
that contains newlines.
The newlines are important.
"""
my_dict = {
'foo': 'bar',
'string': LONG_STRING
}
Try this Code
List itemStates = new List();
for (int i = 0; i < 10; i++)
{
itemStates.Add(new ItemState { Id = i.ToString() });
dataGridView1.DataSource = itemStates;
dataGridView1.DataBind();
System.Threading.Thread.Sleep(500);
}

'href' : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
'type' : 'swf', // <--add a comma here

return false;
});

Why Oracle did such a poor way to point to java is beyond me. We solved this problem by creating a new link to the JDK
mklink /d C:\ProgramData\Oracle\Java\javapath "C:\Program Files\Java\jdk1.8.0_40\bin\"
The same would work for a JRE if that is all that is required.
This replaces the old symlinks in C:\ProgramData\Oracle\Java\javapath
(if they existed previously)
According https://apiblueprint.org/documentation/examples/13-named-endpoints.html is a resource a "general" place of storage of the given entity - e.g. /customers/30654/orders, whereas an endpoint is the concrete action (HTTP Method) over the given resource. So one resource can have multiple endpoints.
In a regular expression, you can "capture" parts of the matched string with (brackets)
; in this case, you are capturing the (^|_)
and ([a-z])
parts of the match. These are numbered starting at 1, so you have back-references 1 and 2. Match 0 is the whole matched string.
The /e
modifier takes a replacement string, and substitutes backslash followed by a number (e.g. \1
) with the appropriate back-reference - but because you're inside a string, you need to escape the backslash, so you get '\\1'
. It then (effectively) runs eval
to run the resulting string as though it was PHP code (which is why it's being deprecated, because it's easy to use eval
in an insecure way).
The preg_replace_callback
function instead takes a callback function and passes it an array containing the matched back-references. So where you would have written '\\1'
, you instead access element 1 of that parameter - e.g. if you have an anonymous function of the form function($matches) { ... }
, the first back-reference is $matches[1]
inside that function.
So a /e
argument of
'do_stuff(\\1) . "and" . do_stuff(\\2)'
could become a callback of
function($m) { return do_stuff($m[1]) . "and" . do_stuff($m[2]); }
Or in your case
'strtoupper("\\2")'
could become
function($m) { return strtoupper($m[2]); }
Note that $m
and $matches
are not magic names, they're just the parameter name I gave when declaring my callback functions. Also, you don't have to pass an anonymous function, it could be a function name as a string, or something of the form array($object, $method)
, as with any callback in PHP, e.g.
function stuffy_callback($things) {
return do_stuff($things[1]) . "and" . do_stuff($things[2]);
}
$foo = preg_replace_callback('/([a-z]+) and ([a-z]+)/', 'stuffy_callback', 'fish and chips');
As with any function, you can't access variables outside your callback (from the surrounding scope) by default. When using an anonymous function, you can use the use
keyword to import the variables you need to access, as discussed in the PHP manual. e.g. if the old argument was
'do_stuff(\\1, $foo)'
then the new callback might look like
function($m) use ($foo) { return do_stuff($m[1], $foo); }
preg_replace_callback
is instead of the /e
modifier on the regex, so you need to remove that flag from your "pattern" argument. So a pattern like /blah(.*)blah/mei
would become /blah(.*)blah/mi
./e
modifier used a variant of addslashes()
internally on the arguments, so some replacements used stripslashes()
to remove it; in most cases, you probably want to remove the call to stripslashes
from your new callback.I disagree, but the solution to increase the file size in php.ini
or .htaccess
won't work if the user sends a file larger than allowed by the server application.
I suggest validating this on the front end. For example:
$(document).ready(function() {
$ ('#your_input_file_id').bind('change', function() {
var fileSize = this.files[0].size/1024/1024;
if (fileSize > 2) { // 2M
alert('Your custom message for max file size exceeded');
$('#your_input_file_id').val('');
}
});
});

make sure when you add your proxy entries to the server file, you add them under the [global] group. (That seemed to make the difference for me under ubuntu.)

Change display:inline to display:inline-block
.test {

display:inline-block;
overflow: auto;
white-space: nowrap;
margin:0px auto;

}
I've changed my android:minSdkVersion

Now I can install my app successfully.
A solution is add the corresponding Debian package way to your repository. For this, type the below commands:
echo "deb ftp.us.debian.org/debian wheezy main" >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get install ia32-libs-i386
The first line writes in the end of the sources.list
file the package way.
This works for me. I wish that helps you.
Alternative approach if .htaccess customization is not ideal option:
I've created simple redirect server for public use. Just add A or CNAME record:
CNAME r.simpleredirect.net
A 89.221.218.22
More info: https://simpleredirect.net
You may use this too
Sub CopyPaste()
Sheet1.Range("A:A").Copy
Sheet2.Activate
col = 1
Do Until Sheet2.Cells(1, col) = ""
col = col + 1
Loop
Sheet2.Cells(1, col).PasteSpecial xlPasteValues
End Sub
As of March 30, 2012, I have tried and failed to get the sloonz fork on GitHub to open images. I got it to compile ok, but it didn't actually work. I also tried building gohlke's library, and it compiled also but failed to open any images. Someone mentioned PythonMagick above, but it only compiles on Windows. See PythonMagick on the wxPython wiki.
PIL was last updated in 2009, and while it's website says they are working on a Python 3 port, it's been 3 years, and the mailing list has gone cold.
To solve my Python 3 image manipulation problem, I am using subprocess.call()
to execute ImageMagick shell commands. This method works.
The most effective way to do it without repeating your code is use of HAVING instead of WHERE
SELECT logcount, logUserID, maxlogtm
, DATEDIFF(day, maxlogtm, GETDATE()) AS daysdiff
FROM statslogsummary
HAVING daysdiff > 120
First, convert the timestamp using the built-in eloquent functionality, as described in this answer.
Then you can just use Carbon's min()
or max()
function for comparison. For example:
$dt1 = Carbon::create(2012, 1, 1, 0, 0, 0);
$dt2 = Carbon::create(2014, 1, 30, 0, 0, 0);
echo $dt1->min($dt2);
This will echo
the lesser of the two dates, which in this case is $dt1
.
| is bitwise or, || is logical or.
Here is another try:
function stringToColor(str){
var hash = 0;
for(var i=0; i < str.length; i++) {
hash = str.charCodeAt(i) + ((hash << 3) - hash);
}
var color = Math.abs(hash).toString(16).substring(0, 6);
return "#" + '000000'.substring(0, 6 - color.length) + color;
}

You are not selecting multiple indexes with PriceList[0][1][2][3][4][5][6] , instead each [] is going into a sub index.
Try this
PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))
PriceList[0:7]=[PizzaChange]*7
PriceList[7:11]=[PizzaChange+3]*4
Since at the time of installing of any module it mainly put corresponding .pm files in respective directories.
So if you want to remove module only for some testing purpose or temporarily best is to find the path where module is stored using perldoc -l <MODULE>
and then simply move the module from there to some other location.
This approach can also be tried as a more permanent solution but i am not aware of any negative consequences as i do it mainly for testing.
I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.
It is neither an API nor a framework. It is just an architectural concept. You can find more details here.
I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.
EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.
It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).
Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.
Here's a check-list for file uploading in PHP:
Check php.ini for:
file_uploads = On
post_max_size = 100M
upload_max_filesize = 100M
.htaccess
or .user.ini
if you are on shared hosting and don't have access to php.ini
.phpinfo()
function to verify your
settings are actually being applied. 100M
not 100MB
.Make sure your <form>
tag has the enctype="multipart/form-data"
attribute. No other tag will work, it has to be your FORM tag. Double check that it is spelled correctly. Double check that multipart/form-data is surrounded by STRAIGHT QUOTES, not smart quotes pasted in from Word OR from a website blog (WordPress converts straight quotes to angle quotes!). If you have multiple forms on the page, make sure they both have this attribute. Type them in manually, or try straight single quotes typed in manually.
Make sure you do not have two input file fields with the same name
attribute. If you need to support multiple, put square brackets at the end of the name:
<input type="file" name="files[]">
<input type="file" name="files[]">
Make sure your tmp and upload directories have the correct read+write permissions set. The temporary upload folder is specified in PHP settings as upload_tmp_dir
.
Make sure your file destination and tmp/upload directories do not have spaces in them.
Make sure all <form>
's on your page have </form>
close tags.
Make sure your FORM tag has method="POST"
. GET requests do not support multipart/form-data uploads.
Make sure your file input tag has a NAME attribute. An ID attribute is NOT sufficient! ID attributes are for use in the DOM, not for POST payloads.
Make sure you are not using Javascript to disable your <input type="file">
field on submission
Make sure you're not nesting forms like <form><form></form></form>
Check your HTML structure for invalid/overlapping tags like <div><form></div></form>
Also make sure that the file you are uploading does not have any non-alphanumeric characters in it.
Once, I just spent hours trying to figure out why this was happening to me all of a sudden. It turned out that I had modified some of the PHP settings in .htaccess
, and one of them (not sure which yet) was causing the upload to fail and $_FILES
to be empty.
You could potentially try avoiding underscores (_
) in the name=""
attribute of the <input>
tag
Try uploading very small files to narrow down whether it's a file-size issue.
Check your available disk space. Although very rare, it is mentioned in this PHP Manual page comment:
If the $_FILES array suddenly goes mysteriously empty, even though your form seems correct, you should check the disk space available for your temporary folder partition. In my installation, all file uploads failed without warning. After much gnashing of teeth, I tried freeing up additional space, after which file uploads suddenly worked again.
Be sure that you're not submitting the form through an AJAX POST request instead of a normal POST request that causes a page to reload. I went through each and every point in the list above, and finally found out that the reason due to which my $_FILES variable was empty was that I was submitting the form using an AJAX POST request. I know that there are methods to upload files using ajax too, but this could be a valid reason why your $_FILES array is empty.
Source for some of these points:
http://getluky.net/2004/10/04/apachephp-_files-array-mysteriously-empty/
There are several possibilities (note that the those long values aren't the same as the Unix epoch.
For your example (to reverse ToFileTime()
) just use DateTime.FromFileTime(t)
.
change the try_files
to point to the index.php
path, in the "Laravel" that you mentioned it should be something like this
location / {
try_files $uri $uri/ /public/index.php$request_uri;
}
And in the "codeigniter" project try it like this
location / {
try_files $uri $uri/ /public_web/index.php$request_uri;
}
Be careful, the solution proposed with $a = array_combine($a, $a);
will not work for numeric values.
I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384)
to be the keys as well as the values however PHP manual states:
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
So I solved it like this:
foreach($array as $key => $val) {
$new_array[$val]=$val;
}
Combine unpacking with the print function:
# in 2.6 <= python < 3.0, 3.0 + the print function is native
from __future__ import print_function
mylist = ['foo', 'bar', 'some other value', 1,2,3,4]
print(*mylist)
Google has a YouTube Android Player API that enables you to incorporate video playback functionality into your Android applications. The API itself is very easy to use and works well. For example, here is how to create a new activity to play a video using the API.
Intent intent = YouTubeStandalonePlayer.createVideoIntent(this, "<<YOUTUBE_API_KEY>>", "<<Youtube Video ID>>", 0, true, false);
startActivity(intent);

Install AWS CLI:
curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
sudo apt-get install unzip
unzip awscli-bundle.zip
sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws
Get the tags for the current instance:
aws ec2 describe-tags --filters "Name=resource-id,Values=`ec2metadata --instance-id`"
Outputs:
{
"Tags": [
{
"ResourceType": "instance",
"ResourceId": "i-6a7e559d",
"Value": "Webserver",
"Key": "Name"
}
]
}
Use a bit of perl to extract the tags:
aws ec2 describe-tags --filters \
"Name=resource-id,Values=`ec2metadata --instance-id`" | \
perl -ne 'print "$1\n" if /\"Value\": \"(.*?)\"/'
Returns:
Webserver
Create the following method:
public class Logger {
public static void log(String message) {
PrintWriter out = new PrintWriter(new FileWriter("output.txt", true), true);
out.write(message);
out.close();
}
}
(I haven't included the proper IO handling in the above class, and it won't compile - do it yourself. Also consider configuring the file name. Note the "true" argument. This means the file will not be re-created each time you call the method)
Then instead of System.out.println(str)
call Logger.log(str)
This manual approach is not preferable. Use a logging framework - slf4j, log4j, commons-logging, and many more

Per the jQuery documentation, try this:
$('input[inputName\\[\\]=someValue]')
[EDIT] However, I'm not sure that's the right syntax for your selector. You probably want:
$('input[name="inputName[]"][value="someValue"]')
Another option could be using bootstrap select. On their own words:
A custom select / multiselect for Bootstrap using button dropdown, designed to behave like regular Bootstrap selects.
The following is a summary of what you need to do under OS X Mavericks (10.9). This is all summarized in
http://hints.macworld.com/article.php?story=20060825071728278
Go to Terminal->Preferences->Settings->Advanced.
Under International, make sure the character encoding is set to Unicode (UTF-8).
Also, and this is key: under Emulation, make sure that Escape non-ASCII input with Control-V is unchecked (i.e. is not set).
These two settings fix things for Terminal.
Make sure your locale is set to something that ends in .UTF-8
. Type locale
and look at the LC_CTYPE
line. If it doesn't say something like en_US.UTF-8
(the stuff before the dot might change if you are using a non-US-English locale), then in your Bash .profile
or .bashrc
in your home directory, add a line like this:
export LC_CTYPE=en_US.UTF-8
This will fix things for command-line programs in general.
Add the following lines to .inputrc
in your home directory (create it if necessary):
set meta-flag on
set input-meta on
set output-meta on
set convert-meta off
This makes Bash be eight-bit clean, so it will pass UTF-8 characters in and out without messing with them.
Keep in mind you will have to restart Bash (e.g. close and reopen the Terminal window) to get it to pay attention to all the settings you make in 2 and 3 above.

Another way-too-complicated workaround, with the benefit of not having to re-install the application as the previous workaround required. This requires that you have access to the msi (or a setup.exe with the msi embedded).
If you have Visual Studio 2012 (or possibly other editions) and install the free "InstallShield LE", then you can create a new setup project using InstallShield.
One of the configuration options in the "Organize your Setup" step is called "Upgrade Paths". Open the properties for Upgrade Paths, and in the left pane right click "Upgrade Paths" and select "New Upgrade Path" ... now browse to the msi (or setup.exe containing the msi) and click "open". The upgrade code will be populated for you in the settings page in the right pane which you should now see.
You can use this sql statement to get the history for any date:

You need to reduce the height of UICollectionView

It can be like this
obj = model.objects.filter(id=emp_id)[0]
or
obj = model.objects.latest('id')
I think this may work.

If I understand your question correctly, I've made a fiddle that has this working correctly. This issue is with how you're assigning the event handlers and as others have said you have over riding event handlers. The current jQuery best practice is to use on()
to register event handlers. Here's a link to the jQuery docs about on
: link
Your original solution was pretty close but the way you added the event handlers is a bit confusing. It's considered best practice to not add events to HTML elements. I recommend reading up on Unobstrusive JavaScript.
Here's the JavaScript code. I added a counter variable so you can see that it is working correctly.
$('#answer').on('click', function() {
feedback('hey there');
});
var counter = 0;
function feedback(message) {
$('#feedback').remove();
$('.answers').append('<div id="feedback">' + message + ' ' + counter + '</div>');
counter++;
}
Another aproach is:
let result = { ...item, location : { ...response } }
But Object spread isn't yet standardized.

I recently switch to set strict-mode -version 2.0 and my null tests failed.
I added a function:
#use in strict mode to validate property exists before using
function exists {
param($obj,$prop)
try {
if ($null -ne $obj[$prop]) {return $true}
return $false
} catch {
return $false
}
return $false
}
Now I code
if (exists $run main) { ...
rather than
if ($run.main -ne $null) { ...
and we are on our way. Seems to work on objects and hashtables
As an unintended benefit it is less typing.
As Fragments Version 1.3.0-alpha01
The setRetainInstance() method on Fragments has been deprecated. With the introduction of ViewModels, developers have a specific API for retaining state that can be associated with Activities, Fragments, and Navigation graphs. This allows developers to use a normal, not retained Fragment and keep the specific state they want retained separate, avoiding a common source of leaks while maintaining the useful properties of a single creation and destruction of the retained state (namely, the constructor of the ViewModel and the onCleared() callback it receives).
Here is how to display the date as (year/month/day) :
from datetime import datetime
now = datetime.now()
print '%s/%s/%s' % (now.year, now.month, now.day)
Try inheriting from ConfigurationSection. This blog post by Phil Haack has an example.
Confirmed, per the documentation for IConfigurationSectionHandler:
In .NET Framework version 2.0 and above, you must instead derive from the ConfigurationSection class to implement the related configuration section handler.
A GUID is a 128 bit integer (its just in hex rather than base 10). With .NET 4 use http://msdn.microsoft.com/en-us/library/dd268285%28v=VS.100%29.aspx like so:

If you don't have .NET 4 you can look at IntX or Solver Foundation.
The data from the request (content, inputs, files, querystring values) is all on this object HttpContext.Current.Request
To read the posted content
StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
string requestFromPost = reader.ReadToEnd();
To navigate through the all inputs
foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
string value = HttpContext.Current.Request.Form[key];
}
OK, nevermind.. I found the trick:

You can just use the pipe on its own:
"string1|string2"
for example:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|string2", "blah"));
Output:
blah, blah, string3
The main reason to use parentheses is to limit the scope of the alternatives:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(1|2)", "blah"));
has the same output. but if you just do this:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|2", "blah"));
you get:
blah, stringblah, string3
because you've said "string1" or "2".
If you don't want to capture that part of the expression use ?:
:
String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(?:1|2)", "blah"));
There is a useful tool written using perl called Maatkit. It has several database comparison and syncing tools among other things.
This may be a long shot, but Crystal Reports for Eclipse is free. I'm not sure if it will work, but if all you need is to edit some static text, you could get that version of CR and get the job done.
I see this has been answered; however, I feel this link provides appropriate information for what formatting is supported in various email clients.

It's worth noting that GMail and Outlook are two of the pickiest to format HTML email for.
Okay so what helped me was iterating backwards. I was trying to remove an entry from a list but iterating upwards and it screwed up the loop because the entry didn't exist anymore:
for (int x = myList.Count - 1; x > -1; x--)
{
myList.RemoveAt(x);
}
It's not exactly the answer to this question but I dealt with this problem with the Shift + Win + [left,right] arrow keys
shortcut. You can move the currently active window to another monitor with it.
In my case onChange event was typed as React.ChangeEvent:
onChange={ (e: React.ChangeEvent<HTMLSelectElement>) => {
console.warn('onChange TextInput value: ' + e.target.value);
}
}
There is no method append()
on arrays. Instead as already suggested a List object can service the need for dynamically inserting elements eg.
List<String> where = new ArrayList<String>();
where.add(ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1");
where.add(ContactsContract.Contacts.IN_VISIBLE_GROUP + "=1");
Or if you are really keen to use an array:
String[] where = new String[]{
ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1",
ContactsContract.Contacts.IN_VISIBLE_GROUP + "=1"
};
but then this is a fixed size and no elements can be added.
Put this in /etc/init
(Use /etc/systemd
in Ubuntu 15.x)
mystartupscript.conf
start on runlevel [2345]
stop on runlevel [!2345]
exec /path/to/script.py
By placing this conf file there you hook into ubuntu's upstart service that runs services on startup.
manual starting/stopping is done with
sudo service mystartupscript start
and
sudo service mystartupscript stop
If you are using react-redux for your application and if you want to show data which is in the redux store, you can set "checked" option as below.
<label>Male</label>
<input
type="radio"
name="gender"
defaultChecked={this.props.gender == "0"}
/>
<label>Female</label>
<input
type="radio"
name="gender"
defaultChecked={this.props.gender == "1"}
/>
If your config file is in a different path than classpath, you can add the configuration file path as a system property:
java -Dapp.config.path=path_to_config_file -jar your.jar
Try this
@font-face { _x000D_
src: url(fonts/Market_vilis.ttf) format("truetype");_x000D_
}_x000D_
div.FontMarket { _x000D_
font-family: Market Deco;_x000D_
}
_x000D_
<div class="FontMarket">KhonKaen Market</div>
_x000D_

You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

Did you try something like:

I have come up with a simpler solution.
Get the returned value of the page name from wp_title(). If empty, print homepage name, otherwise echo the wp_title() value.
<?php $title = wp_title('', false); ?>
Remember to remove the separation with the first argument and then set display to false to use as an input to the variable. Then just bung the code between your heading, etc. tags.
<?php if ( $title == "" ) : echo "Home"; else : echo $title; endif; ?>
It worked a treat for me and ensuring that the first is declared in the section where you wish to extract the $title
, this can be tuned to return different variables.
The CPPFLAGS
macro is the one to use to specify #include
directories.
Both CPPFLAGS
and CFLAGS
work in your case because the make
(1) rule combines both preprocessing and compiling in one command (so both macros are used in the command).
You don't need to specify .
as an include-directory if you use the form #include "..."
. You also don't need to specify the standard compiler include directory. You do need to specify all other include-directories.
The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.

You could try Directory.Exists(path)
and Directory.GetFiles(path)
- probably less overhead (no objects - just strings etc).
On newer versions of Android (post Android 4.2 (Jelly Bean) at least), the setAlpha(int value) method is depreciated. Instead, use the setAlpha(float value)
method that takes a float between 0 and 1 where 0 is complete transparency and 1 is no transparency.

I was able to reproduce this once I upgraded to PHP 7. It breaks when you try to force array elements into a string.
$params = '';
foreach ($foo) {
$index = 0;
$params[$index]['keyName'] = $name . '.' . $fileExt;
}
After changing:
$params = '';
to:
$params = array();
I stopped getting the error. I found the solution in this bug report thread. I hope this helps.
Posting, since it might be useful for someone in the future:
For me, when I got here, the solution was browser cache. Had to hard refresh Chrome (cmd/ctrl+shift+R) to get the new styles applied, it seems the old ones got cached really "deep".

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

Re: craigts's response, for anyone having trouble with using either False or None parameters for index_col, such as in cases where you're trying to get rid of a range index, you can instead use an integer to specify the column you want to use as the index. For example:
df = pd.read_csv('file.csv', index_col=0)
The above will set the first column as the index (and not add a range index in my "common case").
Given the popularity of this answer, I thought i'd add some context/ a demo:
# Setting up the dummy data
In [1]: df = pd.DataFrame({"A":[1, 2, 3], "B":[4, 5, 6]})
In [2]: df
Out[2]:
A B
0 1 4
1 2 5
2 3 6
In [3]: df.to_csv('file.csv', index=None)
File[3]:
A B
1 4
2 5
3 6
Reading without index_col or with None/False will all result in a range index:
In [4]: pd.read_csv('file.csv')
Out[4]:
A B
0 1 4
1 2 5
2 3 6
# Note that this is the default behavior, so the same as In [4]
In [5]: pd.read_csv('file.csv', index_col=None)
Out[5]:
A B
0 1 4
1 2 5
2 3 6
In [6]: pd.read_csv('file.csv', index_col=False)
Out[6]:
A B
0 1 4
1 2 5
2 3 6
However, if we specify that "A" (the 0th column) is actually the index, we can avoid the range index:
In [7]: pd.read_csv('file.csv', index_col=0)
Out[7]:
B
A
1 4
2 5
3 6

When you make the input, set it to be readonly.
<input type="text" name="datepicker" id="datepicker" readonly="readonly" />
The immediate problem is you have is with quoting: by using double quotes ("..."
), your variable references are instantly expanded, which is probably not what you want.
Use single quotes instead - strings inside single quotes are not expanded or interpreted in any way by the shell.
(If you want selective expansion inside a string - i.e., expand some variable references, but not others - do use double quotes, but prefix the $
of references you do not want expanded with \
; e.g., \$var
).
However, you're better off using a single here-doc[ument], which allows you to create multi-line stdin
input on the spot, bracketed by two instances of a self-chosen delimiter, the opening one prefixed by <<
, and the closing one on a line by itself - starting at the very first column; search for Here Documents
in man bash
or at http://www.gnu.org/software/bash/manual/html_node/Redirections.html.
If you quote the here-doc delimiter (EOF
in the code below), variable references are also not expanded. As @chepner points out, you're free to choose the method of quoting in this case: enclose the delimiter in single quotes or double quotes, or even simply arbitrarily escape one character in the delimiter with \
:
echo "creating new script file."
cat <<'EOF' > "$servfile"
#!/bin/bash
read -p "Please enter a service: " ser
servicetest=`getsebool -a | grep ${ser}`
if [ $servicetest > /dev/null ]; then
echo "we are now going to work with ${ser}"
else
exit 1
fi
EOF
As @BruceK notes, you can prefix your here-doc delimiter with -
(applied to this example: <<-"EOF"
) in order to have leading tabs stripped, allowing for indentation that makes the actual content of the here-doc easier to discern.
Note, however, that this only works with actual tab characters, not leading spaces.
Employing this technique combined with the afterthoughts regarding the script's content below, we get (again, note that actual tab chars. must be used to lead each here-doc content line for them to get stripped):
cat <<-'EOF' > "$servfile"
#!/bin/bash
read -p "Please enter a service name: " ser
if [[ -n $(getsebool -a | grep "${ser}") ]]; then
echo "We are now going to work with ${ser}."
else
exit 1
fi
EOF
Finally, note that in bash
even normal single- or double-quoted strings can span multiple lines, but you won't get the benefits of tab-stripping or line-block scoping, as everything inside the quotes becomes part of the string.
Thus, note how in the following #!/bin/bash
has to follow the opening '
immediately in order to become the first line of output:
echo '#!/bin/bash
read -p "Please enter a service: " ser
servicetest=$(getsebool -a | grep "${ser}")
if [[ -n $servicetest ]]; then
echo "we are now going to work with ${ser}"
else
exit 1
fi' > "$servfile"
Afterthoughts regarding the contents of your script:
$(...)
is preferred over `...`
for command substitution nowadays.${ser}
in the grep
command, as the command will likely break if the value contains embedded spaces (alternatively, make sure that the valued read contains no spaces or other shell metacharacters).[[ -n $servicetest ]]
to test whether $servicetest
is empty (or perform the command substitution directly inside the conditional) - [[ ... ]]
- the preferred form in bash
- protects you from breaking the conditional if the $servicetest
happens to have embedded spaces; there's NEVER a need to suppress stdout output inside a conditional (whether [ ... ]
or [[ ... ]]
, as no stdout output is passed through; thus, the > /dev/null
is redundant (that said, with a command substitution inside a conditional, stderr output IS passed through).I had the same error. Basically, I suspect that the path cannot start either with "U" or "User" after "C:\". I changed my directory to "c:\file_name.png" by putting the file that I want to access from python right under the 'c:\' path.
In your case, if you have to access the "python" folder, perhaps reinstall the python, and change the installation path to something like "c:\python". Otherwise, just avoid the "...\User..." in your path, and put your project under C:.
From version 0.21.1 you can also use .at
method. There are some differences compared to .loc
as mentioned here - pandas .at versus .loc, but it's faster on single value replacement
$("myDiv").hide();
and $("myDiv").show();
does not work in Internet Explorer that well.
The way I got around this was to get the html content of myDiv
using .html()
.
I then wrote it to a newly created DIV. I then appended the DIV to the body and appended the content of the variable Content
to the HiddenField
then read that contents from the newly created div when I wanted to show the DIV.
After I used the .remove()
method to get rid of the DIV that was temporarily holding my DIVs html.
var Content = $('myDiv').html();
$('myDiv').empty();
var hiddenField = $("<input type='hidden' id='myDiv2'>");
$('body').append(hiddenField);
HiddenField.val(Content);
and then when I wanted to SHOW the content again.
var Content = $('myDiv');
Content.html($('#myDiv2').val());
$('#myDiv2').remove();
This was more reliable that the .hide()
& .show()
methods.

What is happening here is that database route does not accept any url methods.
I would try putting the url methods in the app route just like you have in the entry_page function:
@app.route('/entry', methods=['GET', 'POST'])
def entry_page():
if request.method == 'POST':
date = request.form['date']
title = request.form['blog_title']
post = request.form['blog_main']
post_entry = models.BlogPost(date = date, title = title, post = post)
db.session.add(post_entry)
db.session.commit()
return redirect(url_for('database'))
else:
return render_template('entry.html')
@app.route('/database', methods=['GET', 'POST'])
def database():
query = []
for i in session.query(models.BlogPost):
query.append((i.title, i.post, i.date))
return render_template('database.html', query = query)
I had the exact same issue. However when I tried opening the website manually in the browser the certificate was correct, but in the details the name was "DONOTTRUST".
The difference of certificate was caused by Fiddler that was running in background and decrypting all HTTPS content before reencrypting it.
To fix my problem, just close Fiddler on machine. If you need to keep Fiddler opened, then you can uncheck Decrypt SSL in Fiddler Settings.
One liner explanation
The standard versioning system is major.minor.build (e.g. 2.4.1)
npm checks and fixes the version of a particular package based on these characters
~ : major version is fixed, minor version is fixed, matches any build number
e.g. : ~2.4.1 means it will check for 2.4.x where x is anything
^ : major version is fixed, matches any minor version, matches any build number
e.g. : ^2.4.1 means it will check for 2.x.x where x is anything
$str = trim(preg_replace('/\s+/',' ', $str));
The above line of code will remove extra spaces, as well as leading and trailing spaces.
Tried pushy's answer above and it worked for the most part. However, in certain circumstances, I would see this exception:
java.lang.String cannot be cast to java.lang.ProcessEnvironment$Variable
This turns out to happen when the method was called more than once, owing to the implementation of certain inner classes of ProcessEnvironment.
If the setEnv(..)
method is called more than once, when the keys are retrieved from the theEnvironment
map, they are now strings (having been put in as strings by the first invocation of setEnv(...)
) and cannot be cast to the map's generic type, Variable,
which is a private inner class of ProcessEnvironment.
A fixed version (in Scala), is below. Hopefully it isn't too difficult to carry over into Java.

If you need to keep the original array because you have other references to it that should be updated too, you can clear it without creating a new array by setting its length to zero:

string
is synonym for System.String
type, They are identical.
Values are also identical: string.Empty == String.Empty == ""
I would not use character constant "" in code, rather string.Empty
or String.Empty
- easier to see what programmer meant.
Between string
and String
I like lower case string
more just because I used to work with Delphi for lot of years and Delphi style is lowercase string
.
So, if I was your boss, you would be writing string.Empty

}
Then:
var sz = JsonConvert.SerializeObject( sampleGroupInstance );

If settings.functionName
