I eventually figured out there was a byte mark exception and removed it using this code:
string _byteOrderMarkUtf8 = Encoding.UTF8.GetString(Encoding.UTF8.GetPreamble());
if (xml.StartsWith(_byteOrderMarkUtf8))
{
var lastIndexOfUtf8 = _byteOrderMarkUtf8.Length-1;
xml = xml.Remove(0, lastIndexOfUtf8);
}
XmlDataDocument xmldoc = new XmlDataDocument();
XmlNodeList xmlnode ;
int i = 0;
string str = null;
FileStream fs = new FileStream("product.xml", FileMode.Open, FileAccess.Read);
xmldoc.Load(fs);
xmlnode = xmldoc.GetElementsByTagName("Product");
You can loop through xmlnode and get the data...... C# XML Reader

I was able to solve a similar problem with simple URL parameters and auto refresh.
You can get the values from the URL parameters, do whatever you want with them and simply refresh the page.

string variable = Request.QueryString["parameterName"];

Invoking an empty time.Time
struct literal will return Go's zero date. Thus, for the following print statement:
fmt.Println(time.Time{})
The output is:
0001-01-01 00:00:00 +0000 UTC
For the sake of completeness, the official documentation explicitly states:
The zero value of type Time is January 1, year 1, 00:00:00.000000000 UTC.
There are 2 differences:
2 methods creating a user and granting some privileges to him
create user userName identified by password;
grant connect to userName;
and
grant connect to userName identified by password;
do exactly the same. It creates a user and grants him the connect role.
different outcome
resource is a role in oracle, which gives you the right to create objects (tables, procedures, some more but no views!). ALL PRIVILEGES grants a lot more of system privileges.
To grant a user all privileges run you first snippet or
grant all privileges to userName identified by password;
Use below code for HTML5 validation pattern alphanumeric without / with space :-
for HTML5 validation pattern alphanumeric without space :- onkeypress="return event.charCode >= 48 && event.charCode <= 57 || event.charCode >= 97 && event.charCode <= 122 || event.charCode >= 65 && event.charCode <= 90"
for HTML5 validation pattern alphanumeric with space :-
onkeypress="return event.charCode >= 48 && event.charCode <= 57 || event.charCode >= 97 && event.charCode <= 122 || event.charCode >= 65 && event.charCode <= 90 || event.charCode == 32"
The answer here worked better for me as it isolates the search on the hashtag, not just returning results that contain the search string. In the answer above you would still need to parse the JSON response to see if the entities.hashtags array is not empty.
Here is my attempt, using Node's assert module + npm package object-hash.
I suppose that you would like to check if two arrays contain the same objects, even if those objects are ordered differently between the two arrays.
var assert = require('assert');
var hash = require('object-hash');
var obj1 = {a: 1, b: 2, c: 333},
obj2 = {b: 2, a: 1, c: 444},
obj3 = {b: "AAA", c: 555},
obj4 = {c: 555, b: "AAA"};
var array1 = [obj1, obj2, obj3, obj4];
var array2 = [obj3, obj2, obj4, obj1]; // [obj3, obj3, obj2, obj1] should work as well
// calling assert.deepEquals(array1, array2) at this point FAILS (throws an AssertionError)
// even if array1 and array2 contain the same objects in different order,
// because array1[0].c !== array2[0].c
// sort objects in arrays by their hashes, so that if the arrays are identical,
// their objects can be compared in the same order, one by one
var array1 = sortArrayOnHash(array1);
var array2 = sortArrayOnHash(array2);
// then, this should output "PASS"
try {
assert.deepEqual(array1, array2);
console.log("PASS");
} catch (e) {
console.log("FAIL");
console.log(e);
}
// You could define as well something like Array.prototype.sortOnHash()...
function sortArrayOnHash(array) {
return array.sort(function(a, b) {
return hash(a) > hash(b);
});
}
Give the command SHOW CREATE TABLE whatever
Then look at the table definition.
It probably has a line like this
logtime TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
in it. DEFAULT CURRENT_TIMESTAMP
means that any INSERT
without an explicit time stamp setting uses the current time. Likewise, ON UPDATE CURRENT_TIMESTAMP
means that any update without an explicit timestamp results in an update to the current timestamp value.
You can control this default behavior when creating your table.
Or, if the timestamp column wasn't created correctly in the first place, you can change it.
ALTER TABLE whatevertable
CHANGE whatevercolumn
whatevercolumn TIMESTAMP NOT NULL
DEFAULT CURRENT_TIMESTAMP
ON UPDATE CURRENT_TIMESTAMP;
This will cause both INSERT and UPDATE operations on the table automatically to update your timestamp column. If you want to update whatevertable
without changing the timestamp, that is,
To prevent the column from updating when other columns change
then you need to issue this kind of update.
UPDATE whatevertable
SET something = 'newvalue',
whatevercolumn = whatevercolumn
WHERE someindex = 'indexvalue'
This works with TIMESTAMP
and DATETIME
columns. (Prior to MySQL version 5.6.5 it only worked with TIMESTAMP
s) When you use TIMESTAMP
s, time zones are accounted for: on a correctly configured server machine, those values are always stored in UTC and translated to local time upon retrieval.
In order to get rgba integer value instead of float value, we can do
rgba = cmap(0.5,bytes=True)
So to simplify the code based on answer from Ffisegydd, the code would be like this:
#import colormap
from matplotlib import cm
#normalize item number values to colormap
norm = matplotlib.colors.Normalize(vmin=0, vmax=1000)
#colormap possible values = viridis, jet, spectral
rgba_color = cm.jet(norm(400),bytes=True)
#400 is one of value between 0 and 1000
i don't know if this answer can be found on the links above, but i just run SQL management studio as Administrator and worked. Hope it helps

on unix systems, use the system kernel to generate a uuid for you.
file_get_contents('/proc/sys/kernel/random/uuid')
Credit Samveen on https://serverfault.com/a/529319/210994
Note!: Using this method to get a uuid does in fact exhaust the entropy pool, very quickly! I would avoid using this where it would be called frequently.
I have created a new library to implement swippable buttons which supports a variety of transitions and expandable buttons like iOS 8 mail app.
https://github.com/MortimerGoro/MGSwipeTableCell
This library is compatible with all the different ways to create a UITableViewCell and its tested on iOS 5, iOS 6, iOS 7 and iOS 8.
Here a sample of some transitions:

Usually this is an OpenSSL version mismatch error, between Apache and PHP. In case Apache loads PHP as a DSO module, its own OpenSSL versions (dlls and libs) will be used. So, in case the PHP extension requires a newer version, it may not find the appropriate interface inside the Apache-loaded DLLS and it will fail to work.
Since you need the PHP extension to load, you need the relevant DLL files to be at least the version of what the PHP module asks for. Supposing that you 're using lastest builds for both Apache and PHP and both having been built with the same MVC version, you can copy the following files:
from the PHP root folder to the Apache2/bin folder, in case you 're confident that the PHP build is newer than the Apache build.
In the opposite case, you can copy the same files from the Apache BIN to the PHP root.
In any case, backup the contents of the APache and PHP folders beforehand.
Adding the PHP path as an enviromental variable will give priority to this path for loading the relevant DLLs and may solve the problem. However, you lose in server portability. Additionally, if you have also added the Apache PATH as a variable and the OpenSSL versions are way different (up to loading different linked DLL files), a lot of shit may happen.
A simple solution that can deal with float square root and arbitrary precision using binary search
coded in ruby
include Math
def sqroot_precision num, precision
upper = num
lower = 0
middle = (upper + lower)/2.0
while true do
diff = middle**2 - num
return middle if diff.abs <= precision
if diff > 0
upper = middle
else diff < 0
lower = middle
end
middle = (upper + lower)/2.0
end
end
puts sqroot_precision 232.3, 0.0000000001
I believe the WAVE module does not support recording, just processing existing files. You might want to look at PyAudio for actually recording. WAV is about the world's simplest file format. In paInt16 you just get a signed integer representing a level, and closer to 0 is quieter. I can't remember if WAV files are high byte first or low byte, but something like this ought to work (sorry, I'm not really a python programmer:
from array import array
# you'll probably want to experiment on threshold
# depends how noisy the signal
threshold = 10
max_value = 0
as_ints = array('h', data)
max_value = max(as_ints)
if max_value > threshold:
# not silence
PyAudio code for recording kept for reference:
import pyaudio
import sys
chunk = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 5
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
output=True,
frames_per_buffer=chunk)
print "* recording"
for i in range(0, 44100 / chunk * RECORD_SECONDS):
data = stream.read(chunk)
# check for silence here by comparing the level with 0 (or some threshold) for
# the contents of data.
# then write data or not to a file
print "* done"
stream.stop_stream()
stream.close()
p.terminate()
OK, thanks all for the help.
However the problem was much easier than that.
All I need to do is to fix my JSON to assign the array, to an attribute called data, as following.
{
"data": [{
"name_en": "hello",
"phone": "55555555",
"email": "a.shouman",
"facebook": "https:\/\/www.facebook.com"
}, ...]
}
Maybe something like this, where you could select more than one element if you'd like?
$("#number").each(function(){
$(this).val(parseFloat($(this).val()).toFixed(2));
});
It has to do with the general workflow of Git. You're unlikely to be able to push directly to the main project's repository. I'm not sure if GitHub project's repository support branch-based access control, as you wouldn't want to grant anyone the permission to push to the master branch for example.
The general pattern is as follows:
Without this, it's quite unusual for public projects to let anyone push their own commits directly.
Use empty
- http://php.net/manual/en/function.empty.php.
Example:
$a = '';
if(empty($a)) {
echo 'is empty';
}

You have asked two questions, one in the title about the difference between PNG8 and PNG24, which has received a few answers, namely that PNG24 has 8-bit red, green, and blue channels, and PNG-8 has a single 8-bit index into a palette. Naturally, PNG24 usually has a larger filesize than PNG8. Furthermore, PNG8 usually means that it is opaque or has only binary transparency (like GIF); it's defined that way in ImageMagick/GraphicsMagick.
This is an answer to the other one, "I would like to know that if I use either type in my html page, will there be any error? Or is this only quality matter?"
You can put either type on an HTML page and no, this won't cause an error; the files should all be named with the ".png" extension and referred to that way in your HTML. Years ago, early versions of Internet Explorer would not handle PNG with an alpha channel (PNG32) or indexed-color PNG with translucent pixels properly, so it was useful to convert such images to PNG8 (indexed-color with binary transparency conveyed via a PNG tRNS chunk) -- but still use the .png extension, to be sure they would display properly on IE. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.
The names PNG8 and PNG24 aren't mentioned in the PNG specification, which simply calls them all "PNG". Other names, invented by others, include
There are many more possible combinations including grayscale with 1, 2, 4, 8, or 16-bit samples and indexed PNG with 1, 2, or 4-bit samples (and any of those with transparent or translucent pixels), but those don't have special names.
Video tag supports only video formats (like mp4 etc). Youtube does not expose its raw video files - it only exposes the unique id of the video. Since that id does not correspond to the actual file, video tag cannot be used.
If you do get hold of the actual source file using one of the youtube download sites or soft wares, you will be able to use the video tag. But even then, the url of the actual source will cease to work after a set time. So your video also will work only till then.
Since you already have <Tags>
component calling a function on its parent, you do not need additional state: simply pass the filter to the <Tags>
component as a prop, and use this in rendering your buttons. Like so:
Change your render function inside your <Tags>
component to:
render: function() {
return <div className = "tags">
<button className = {this._checkActiveBtn('')} onClick = {this.setFilter.bind(this, '')}>All</button>
<button className = {this._checkActiveBtn('male')} onClick = {this.setFilter.bind(this, 'male')}>male</button>
<button className = {this._checkActiveBtn('female')} onClick = {this.setFilter.bind(this, 'female')}>female</button>
<button className = {this._checkActiveBtn('blonde')} onClick = {this.setFilter.bind(this, 'blonde')}>blonde</button>
</div>
},
And add a function inside <Tags>
:
_checkActiveBtn: function(filterName) {
return (filterName == this.props.activeFilter) ? "btn active" : "btn";
}
And inside your <List>
component, pass the filter state to the <tags>
component as a prop:
return <div>
<h2>Kids Finder</h2>
<Tags filter = {this.state.filter} onChangeFilter = {this.changeFilter} />
{list}
</div>
Then it should work as intended. Codepen here (hope the link works)
You're trying to declare strategy
twice, and that's why you're getting the above error. The following works without any complaints (compiled with gcc -ansi -pedantic -Wall
):
#include <stdio.h>
enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;
int main(int argc, char** argv){
printf("strategy: %d\n", strategy);
return 0;
}
If instead of the above, the second line were changed to:
...
enum { RANDOM, IMMEDIATE, SEARCH } strategy;
strategy = IMMEDIATE;
...
From the warnings, you could easily see your mistake:
enums.c:5:1: warning: data definition has no type or storage class [enabled by default]
enums.c:5:1: warning: type defaults to ‘int’ in declaration of ‘strategy’ [-Wimplicit-int]
enums.c:5:1: error: conflicting types for ‘strategy’
enums.c:4:36: note: previous declaration of ‘strategy’ was here
So the compiler took strategy = IMMEDIATE
for a declaration of a variable called strategy
with default type int
, but there was already a previous declaration of a variable with this name.
However, if you placed the assignment in the main()
function, it would be a valid code:
#include <stdio.h>
enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;
int main(int argc, char** argv){
strategy=SEARCH;
printf("strategy: %d\n", strategy);
return 0;
}
You might configure your IDE to warn you about potential null dereferencing. E.g. in Eclipse, see Preferences > Java > Compiler > Errors/Warnings/Null analysis.
If you want to define a new API where undefined values make sense, use the Option Pattern (may be familiar from functional languages). It has the following advantages:
Java 8 has a built-in Optional
class (recommended); for earlier versions, there are library alternatives, for example Guava's Optional
or FunctionalJava's Option
. But like many functional-style patterns, using Option in Java (even 8) results in quite some boilerplate, which you can reduce using a less verbose JVM language, e.g. Scala or Xtend.
If you have to deal with an API which might return nulls, you can't do much in Java. Xtend and Groovy have the Elvis operator ?:
and the null-safe dereference operator ?.
, but note that this returns null in case of a null reference, so it just "defers" the proper handling of null.
In 2017 with django 1.11.5 and python 3.6 (from the comment this also works with Python 2.7):
import django
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
django.setup()
The .py
in which you put this code should be in mysite
(the parent one)
At the root of your project type below in the console:
gradlew --version
You will have gradle version with other information (as a sample):
------------------------------------------------------------
Gradle 5.1.1 << Here is the version
------------------------------------------------------------
Build time: 2019-01-10 23:05:02 UTC
Revision: 3c9abb645fb83932c44e8610642393ad62116807
Kotlin DSL: 1.1.1
Kotlin: 1.3.11
Groovy: 2.5.4
Ant: Apache Ant(TM) version 1.9.13 compiled on July 10 2018
JVM: 10.0.2 ("Oracle Corporation" 10.0.2+13)
OS: Windows 10 10.0 amd64
I think for gradle version it uses gradle/wrapper/gradle-wrapper.properties
under the hood.
Try this.
string path = @"E:\AppServ\Example.txt";
if (!File.Exists(path))
{
using (var txtFile = File.AppendText(path))
{
txtFile.WriteLine("The very first line!");
}
}
else if (File.Exists(path))
{
using (var txtFile = File.AppendText(path))
{
txtFile.WriteLine("The next line!");
}
}
One important point that is alluded to but not directly addressed is the difference between "precision" and "scale" and how they are used in the two statements. "precision" is the total number of significant digits in a number. "scale" is the number of digits to the right of the decimal point.
The MathContext constructor only accepts precision and RoundingMode as arguments, and therefore scale is never specified in the first statement.
setScale()
obviously accepts scale as an argument, as well as RoundingMode, however precision is never specified in the second statement.
If you move the decimal point one place to the right, the difference will become clear:
// 1.
new BigDecimal("35.3456").round(new MathContext(4, RoundingMode.HALF_UP));
//result = 35.35
// 2.
new BigDecimal("35.3456").setScale(4, RoundingMode.HALF_UP);
// result = 35.3456
Targeting any element and sending down keys (or up/left/right) seems to work also. I know this is a bit of a hack, but I'm not really into the idea of using JavaScript to solve the scrolling problem either.
For example:
WebElement.sendKeys(Keys.DOWN);
iOS 11.x Swift 4.0 Info.plist needs these two properties
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>We're watching you</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Watch Out</string>
And this code ... making sure of course your a CLLocationManagerDelegate
let locationManager = CLLocationManager()
// MARK location Manager delegate code + more
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
switch status {
case .notDetermined:
print("User still thinking")
case .denied:
print("User hates you")
case .authorizedWhenInUse:
locationManager.stopUpdatingLocation()
case .authorizedAlways:
locationManager.startUpdatingLocation()
case .restricted:
print("User dislikes you")
}
And of course this code too which you can put in viewDidLoad().
locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestLocation()
And these two for the requestLocation to get you going, aka save you having to get out of your seat :)
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error)
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print(locations)
}
You must download Android SDK from this link.
You can really put it anywhere, but the best place at least for me was right in the YOUR USERNAME folder root.
Then you need to set the path by copying the below text, but edit your username into the path, copy the text into Terminal by hitting command+spacebar type terminal.
export PATH = ${PATH}:/Users/**YOURUSERNAME**/android-sdk/platform-tools/
Verify ADB works by hitting command+spacebar and type terminal, and type ADB.
There you go. You have ADB setup on MAC OS X. It works on latest MAC OS X 10.10.3.
Maps have also had factory methods added in Java 9. For up to 10 entries Maps have overloaded constructors that take pairs of keys and values. For example we could build a map of various cities and their populations (according to google in October 2016) as follow:
Map<String, Integer> cities = Map.of("Brussels", 1_139000, "Cardiff", 341_000);
The var-args case for Map is a little bit harder, you need to have both keys and values, but in Java, methods can’t have two var-args parameters. So the general case is handled by taking a var-args method of Map.Entry<K, V>
objects and adding a static entry()
method that constructs them. For example:
Map<String, Integer> cities = Map.ofEntries(
entry("Brussels", 1139000),
entry("Cardiff", 341000)
);
Use log4j in your java program instead. Then you can output to multiple media, create rolling logs, etc. and include timestamps, class names and line numbers.
You certainly can. Others have pointed out correctly that you need to do i += 3
. You can't do what you have posted because all you are doing here is adding i + 3
but never assigning the result back to i
. i++
is just a shorthand for i = i + 1
, similarly i +=3
is a shorthand for i = i + 3
.
Typical usage for conditional removal of error from Model State:
Example:
public ActionResult MyAction(MyViewModel vm)
{
// perform conditional test
// if true, then remove from ModelState (e.g. ModelState.Remove("MyKey")
// Do typical model state validation, inside following if:
// if (!ModelState.IsValid)
// Do rest of logic (e.g. fetching, saving
In your example, keep everything as is and add the logic suggested to your Controller's Action. I'm assuming your ViewModel passed to the controller action has the Person and Senior Person objects with data populated in them from the UI.
The -i
flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/
).
So in your first command, you are actually asking scp
to upload the .pem file itself using your default ssh key. I don't think that is what you want.
Try instead with:
scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads
<script>
$(document).ready(function(){
$('#connectBtn').click(function(e){
e.preventDefault();
})
});
</script>
This will prevent the default action.
One shouldn't use set_yticklabels
to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter
), which is usually undesired. The easiest is to set the respective tick_params
:
ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)
or
ax.tick_params(labelsize=8)
in case both axes shall have the same size.
Of course using the rcParams as in @tmdavison's answer is possible as well.

for row in csv.reader(inputfile):
results.append(row)
Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.
Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append()
just process that line right there.
Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:
import csv
with open('inputfile.txt', newline='') as inputfile:
results = list(csv.reader(inputfile))
private void Form1_Load(object sender, EventArgs e)
{
//Write a file
string text = "The text inside the file.";
System.IO.File.WriteAllText("file_name.txt", text);
//Read a file
string read = System.IO.File.ReadAllText("file_name.txt");
MessageBox.Show(read); //Display text in the file
}

Update: Now supported in most major browsers
document.querySelector("p").closest(".near.ancestor")
Note that this can match selectors, not just classes
https://developer.mozilla.org/en-US/docs/Web/API/Element.closest
For legacy browsers that do not support closest()
but have matches()
one can build selector-matching similar to @rvighne's class matching:
function findAncestor (el, sel) {
while ((el = el.parentElement) && !((el.matches || el.matchesSelector).call(el,sel)));
return el;
}
Of course you can use floats or doubles for "critical" things ... Many applications do nothing but crunch numbers using these datatypes.
You might have misunderstood some of the various caveats regarding floating-point numbers, such as the recommendation to never compare for exact equality, and so on.

I'm betting the problem is that Cygwin is writing Unix line endings (LF) to the file, and you're opening it with a program that expects Windows line-endings (CRLF). To determine if this is the case — and for a bit of a hackish workaround — try:
echo "`date` User `whoami` started the script."$'\r' >> output.log
(where the $'\r'
at the end is an extra carriage-return; it, plus the Unix line ending, will result in a Windows line ending).
Firstly create app.js
file in the directory you want to publish.
var http = require('http');
var fs = require('fs');
var mime = require('mime');
http.createServer(function(req,res){
if (req.url != '/app.js') {
var url = __dirname + req.url;
fs.stat(url,function(err,stat){
if (err) {
res.writeHead(404,{'Content-Type':'text/html'});
res.end('Your requested URI('+req.url+') wasn\'t found on our server');
} else {
var type = mime.getType(url);
var fileSize = stat.size;
var range = req.headers.range;
if (range) {
var parts = range.replace(/bytes=/, "").split("-");
var start = parseInt(parts[0], 10);
var end = parts[1] ? parseInt(parts[1], 10) : fileSize-1;
var chunksize = (end-start)+1;
var file = fs.createReadStream(url, {start, end});
var head = {
'Content-Range': `bytes ${start}-${end}/${fileSize}`,
'Accept-Ranges': 'bytes',
'Content-Length': chunksize,
'Content-Type': type
}
res.writeHead(206, head);
file.pipe(res);
} else {
var head = {
'Content-Length': fileSize,
'Content-Type': type
}
res.writeHead(200, head);
fs.createReadStream(url).pipe(res);
}
}
});
} else {
res.writeHead(403,{'Content-Type':'text/html'});
res.end('Sorry, access to that file is Forbidden');
}
}).listen(8080);
Simply run node app.js
and your server shall be running on port 8080. Besides video it can stream all kinds of files.
You can use array_slice as:
$sliced_array = array_slice($array,0,$N);
LaTeX will usually not indent the first paragraph of a section. This is standard typographical practice. However, if you really want to override this default setting, use the package indentfirst available on CTAN.

sysctl -a | grep threads-max
I target the 1024 pixel monitors (but don't use 100% of that space). I've given up on those with 800x600. I'd rather punish the few with outdated hardware by making them scroll if they need to, versus punishing everyone with new equipment by wasting space.
I suppose it depends on your audience, and the nature of you app though.
Template Syntax Error: is due to many reasons one of them is {{ post.date_posted|date: "F d, Y" }} is the space between colon(:) and quote (") if u remove the space then it work like this ..... {{ post.date_posted|date:"F d, Y" }}
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
I think you are asking about Shrinking image size:
public Bitmap ShrinkBitmap(String file, int width, int height)
{
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
Bitmap bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight / (float) height);
int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth / (float) width);
if(heightRatio > 1 || widthRatio > 1)
{
if(heightRatio > widthRatio)
{
bmpFactoryOptions.inSampleSize = heightRatio;
}
else
{
bmpFactoryOptions.inSampleSize = widthRatio;
}
}
bmpFactoryOptions.inJustDecodeBounds = false;
bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
return bitmap;
}
Status 301 means that the resource (page) is moved permanently to a new location. The client/browser should not attempt to request the original location but use the new location from now on.
Status 302 means that the resource is temporarily located somewhere else, and the client/browser should continue requesting the original url.

This is what's killing you:
task.Wait();
That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...
There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:
private async void Button_Click(object sender, RoutedEventArgs
{
Task<List<MyObject>> task = GetResponse<MyObject>("my url");
var items = await task;
// Presumably use items here
}
Or just:
private async void Button_Click(object sender, RoutedEventArgs
{
var items = await GetResponse<MyObject>("my url");
// Presumably use items here
}
Now instead of blocking until the task has completed, the Button_Click
method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)
Note that I would also rename GetResponse
to GetResponseAsync
for clarity.
To change the panel's background color, use the following code:
myplot + theme(panel.background = element_rect(fill = 'green', colour = 'red'))
To change the color of the plot (but not the color of the panel), you can do:
myplot + theme(plot.background = element_rect(fill = 'green', colour = 'red'))
See here for more theme details Quick reference sheet for legends, axes and themes.

Let's assume you have the following directory structure: -
main/ fold1 fold2 fold3...
folders = glob.glob("main/fold*")
for fold in folders:
abspath = os.path.dirname(os.path.abspath(fold))
fullpath = os.path.join(abspath, sch)

Low reputation (too many years of lurking, sigh) so I can't yet comment inline, but I found the answer from @laktak to be the only one that worked as intended on Ubuntu 18.04 -- using tar -cjf site1.tar.bz2 -C /var/www/site1 .
on my machine resulted in all the files I wanted being under ./
inside the tar.bz2 file, which is probably ok but there is some risk of inconsistent behavior across OSs when un-tarring.
Consider adding this to your CSS to resolve the problem:
button {
margin: 0 auto;
display: block;
}
A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.
Stumbled on this page as well, and then found out this is possible with just javascript (no plugins like ActiveX or Flash), but just in chrome:
https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3
Basically, they added support for a new attribute on the file input element "webkitdirectory". You can use it like this:
<input type="file" id="ctrl" webkitdirectory directory multiple/>
It allows you to select directories. The multiple attribute is a good fallback for browsers that support multiple file selection but not directory selection.
When you select a directory the files are available through the dom object for the control (document.getElementById('ctrl')), just like they are with the multiple attribute. The browsers adds all files in the selected directory to that list recursively.
You can already add the directory attribute as well in case this gets standardized at some point (couldn't find any info regarding that)
A simpler (in my view) solution is to create a new dictionary and update it with the contents of the old one:
my_dict={'a':1}
my_copy = {}
my_copy.update( my_dict )
my_dict['a']=2
my_dict['a']
Out[34]: 2
my_copy['a']
Out[35]: 1
The problem with this approach is it may not be 'deep enough'. i.e. is not recursively deep. good enough for simple objects but not for nested dictionaries. Here is an example where it may not be deep enough:
my_dict1={'b':2}
my_dict2={'c':3}
my_dict3={ 'b': my_dict1, 'c':my_dict2 }
my_copy = {}
my_copy.update( my_dict3 )
my_dict1['b']='z'
my_copy
Out[42]: {'b': {'b': 'z'}, 'c': {'c': 3}}
By using Deepcopy() I can eliminate the semi-shallow behavior, but I think one must decide which approach is right for your application. In most cases you may not care, but should be aware of the possible pitfalls... final example:
import copy
my_copy2 = copy.deepcopy( my_dict3 )
my_dict1['b']='99'
my_copy2
Out[46]: {'b': {'b': 'z'}, 'c': {'c': 3}}
Just to help anyone coming to this page. This is an alternate if you are flexible with using some other icon library.
James is correct that you cannot change the font weight however if you are looking for more modern look for icons then you might consider ionicons
It has both ios and android versions for icons.
I was facing the same issue with jenkins ssh slave 'jenkinsci/ssh-slave'. However, my case was a bit complicated because it was necessary to pass an argument which contained spaces. I've managed to do it like below (entrypoint in dockerfile is in exec form):
command: ["some argument with space which should be treated as one"]
To do this in Windows CLI environment, the best way I can find is to use the mode command and parse the output.
function getTerminalSizeOnWindows() {
$output = array();
$size = array('width'=>0,'height'=>0);
exec('mode',$output);
foreach($output as $line) {
$matches = array();
$w = preg_match('/^\s*columns\:?\s*(\d+)\s*$/i',$line,$matches);
if($w) {
$size['width'] = intval($matches[1]);
} else {
$h = preg_match('/^\s*lines\:?\s*(\d+)\s*$/i',$line,$matches);
if($h) {
$size['height'] = intval($matches[1]);
}
}
if($size['width'] AND $size['height']) {
break;
}
}
return $size;
}
I hope it's useful!
NOTE: The height returned is the number of lines in the buffer, it is not the number of lines that are visible within the window. Any better options out there?
Not with an iterator.
For org.json.JSONArray
, you can do:
for (int i = 0; i < arr.length(); i++) {
arr.getJSONObject(i);
}
For javax.json.JsonArray
, you can do:
for (int i = 0; i < arr.size(); i++) {
arr.getJsonObject(i);
}
this solution is deprecated since 2.3 and will be removed in 3.0, see documentation
$form->getData();
gives you an array for the form parameters
from symfony2 book page 162 (Chapter 12: Forms)
[...] sometimes, you may just want to use a form without a class, and get back an array of the submitted data. This is actually really easy:
public function contactAction(Request $request) {
$defaultData = array('message' => 'Type your message here');
$form = $this->createFormBuilder($defaultData)
->add('name', 'text')
->add('email', 'email')
->add('message', 'textarea')
->getForm();
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
// data is an array with "name", "email", and "message" keys
$data = $form->getData();
}
// ... render the form
}
You can also access POST values (in this case "name") directly through the request object, like so:
$this->get('request')->request->get('name');
Be advised, however, that in most cases using the getData() method is a better choice, since it returns the data (usually an object) after it's been transformed by the form framework.
When you want to access the form token, you have to use the answer of Problematic
$postData = $request->request->get('contact');
because the getData()
removes the element from the array
since 2.3 you should use handleRequest
instead of bindRequest
:
$form->handleRequest($request);
in code there should be coma"," not colon ":"
the code must be $(this).css({'background-color' , '#FFFFEE'});
i hope it helps.

I've found the answer:
You MUST encode your json like this: {"c":21001,"m":"p"}
but not {c:21001,m:"p"}
or {'c':21001,'m':'p'}
Thus, the key of a dict must be wrapped in double quotes:"
, then chrome will preview it as json rather than plain text.

I wanted to simulate a 'Tab' press... Expanding on Trevor's answer, we can see that a special key like 'tab' does get pressed but we don't see the actual result which a 'tab' press would have...

a = (a + 180) % 360 - 180
Beware in many languages the modulo
operation returns a value with the same sign as the dividend (like C, C++, C#, JavaScript, full list here). This requires a custom mod
function like so:
mod = (a, n) -> a - floor(a/n) * n
Or so:
mod = (a, n) -> (a % n + n) % n
If angles are within [-180, 180] this also works:
a = targetA - sourceA
a += (a>180) ? -360 : (a<-180) ? 360 : 0
In a more verbose way:
a = targetA - sourceA
a -= 360 if a > 180
a += 360 if a < -180
Simply use
$(document).height() // - $('body').offset().top
and / or
$(window).height()
instead of $('body').height();
Your code could look more like:
<?php
session_start();
$errorMsg = "";
$validUser = $_SESSION["login"] === true;
if(isset($_POST["sub"])) {
$validUser = $_POST["username"] == "admin" && $_POST["password"] == "password";
if(!$validUser) $errorMsg = "Invalid username or password.";
else $_SESSION["login"] = true;
}
if($validUser) {
header("Location: /login-success.php"); die();
}
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>Login</title>
</head>
<body>
<form name="input" action="" method="post">
<label for="username">Username:</label><input type="text" value="<?= $_POST["username"] ?>" id="username" name="username" />
<label for="password">Password:</label><input type="password" value="" id="password" name="password" />
<div class="error"><?= $errorMsg ?></div>
<input type="submit" value="Home" name="sub" />
</form>
</body>
</html>
Now, when the page is redirected based on the header('LOCATION:wherever.php)
, put session_start()
at the top of the page and test to make sure $_SESSION['login'] === true
. Remember that ==
would be true if $_SESSION['login'] == 1
as well.
Of course, this is a bad idea for security reasons, but my example may teach you a different way of using PHP.
If you only need to find a free port for later use, here is a snippet similar to a previous answer, but shorter, using socketserver:
import socketserver
with socketserver.TCPServer(("localhost", 0), None) as s:
free_port = s.server_address[1]
Note that the port is not guaranteed to remain free, so you may need to put this snippet and the code using it in a loop.
As a sidenote to @Navaneethan 's answer, Jinja2
is able to do "regular" item selections for the list and the dictionary, given we know the key of the dictionary, or the locations of items in the list.
parent_dict = [{'A':'val1','B':'val2', 'content': [["1.1", "2.2"]]},{'A':'val3','B':'val4', 'content': [["3.3", "4.4"]]}]
{% for dict_item in parent_dict %}
This example has {{dict_item['A']}} and {{dict_item['B']}}:
with the content --
{% for item in dict_item['content'] %}{{item[0]}} and {{item[1]}}{% endfor %}.
{% endfor %}
This example has val1 and val2:
with the content --
1.1 and 2.2.
This example has val3 and val4:
with the content --
3.3 and 4.4.
I wanted to add here that most of the snippets for this question will have something like MODE_PRIVATE when using SharedPreferences. Well, MODE_PRIVATE means that whatever you write into this shared preference can only be read by your application only.
Whatever key you pass to getSharedPreferences() method, android creates a file with that name and stores the preference data into it. Also remember that getSharedPreferences() is supposed to be used when you intend to have multiple preference files for your application. If you intend to use single preference file and store all key-value pairs into it then use the getSharedPreference() method. Its weird why everyone (including myself) simply uses getSharedPreferences() flavor without even understanding the difference between the above two.
The following video tutorial should help https://www.youtube.com/watch?v=2PcAQ1NBy98
You are getting this exception because your AWS SDK is unable to load your credentials. What you should do is goto Preferences then goto AWS and add your secret key and access key. So that your project can retrieve both keys.

You'll want to use the formatting macros from inttypes.h.

In my case, spring threw this because i forgot to make an inner class static.
When you found that it doesnt help even adding a no-arg constructor, please check your modifier.
I had the same error, but it was caused by the package manager process port being already used (port 8081).
To fix, I just ran the react-native
by specifying a different port, see below.
react-native run-ios --port 8090
for me the "workaround" solution was to remove the "_normal" from the end of the string

This is a pretty old question, but perhaps this answer can still help someone else.
You can emulate a public constant that is restricted within a class scope by applying the final keyword to a method that returns a pre-defined value, like this:
class Foo {
// This is a private constant
final public MYCONSTANT()
{
return 'MYCONSTANT_VALUE';
}
}
The final keyword on a method prevents an extending class from re-defining the method. You can also place the final keyword in front of the class declaration, in which case the keyword prevents class Inheritance.
To get nearly exactly what Alex was looking for the following code can be used:
final class Constants {
public MYCONSTANT()
{
return 'MYCONSTANT_VALUE';
}
}
class Foo {
static public app()
{
return new Constants();
}
}
The emulated constant value would be accessible like this:
Foo::app()->MYCONSTANT();
(EDITED) I made it so it stops after 100 times
@echo off
goto actual
set /a loopcount=0
:actual
set /a loopcount=%loopcount% + 1
echo %random% %random% %random% %random%
timeout 1 /nobreak>nul
if %loopcount%== 100 goto stop
goto actual
:stop
exit
This will generate 4 random numbers ever 1 second 100 times. Take out the "timeout 1 /nobreak>nul" to make it go super fast.
Here's a solution using the new async/await syntax.
async function testWait() {
alert('going to wait for 5 second');
await wait(5000);
alert('finally wait is over');
}
function wait(time) {
return new Promise(resolve => {
setTimeout(() => {
resolve();
}, time);
});
}
Note: You can call function wait only in async functions
Probably one of the indexes is wrong, either the inner one or the outer one.
I suspect you mean to say [0]
where you say [1]
and [1]
where you say [2]
. Indexes are 0-based in Python.
Statement stmt3 = con.createStatement();
ResultSet rs3 = stmt3.executeQuery("SELECT COUNT(*) AS count FROM "+lastTempTable+" ;");
count = rs3.getInt("count");
If you want to initialize the array to -1
then you can use the following,
memset(array, -1, sizeof(array[0][0]) * row * count)
But this will work 0

Try this if you are using jquery version >=1.9,
var browser;
jQuery.uaMatch = function (ua) {
ua = ua.toLowerCase();
var match = /(chrome)[ \/]([\w.]+)/.exec(ua) ||
/(webkit)[ \/]([\w.]+)/.exec(ua) ||
/(opera)(?:.*version|)[ \/]([\w.]+)/.exec(ua) ||
/(msie) ([\w.]+)/.exec(ua) ||
ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec(ua) ||
/(Trident)[\/]([\w.]+)/.exec(ua) || [];
return {
browser: match[1] || "",
version: match[2] || "0"
};
};
// Don't clobber any existing jQuery.browser in case it's different
if (!jQuery.browser) {
matched = jQuery.uaMatch(navigator.userAgent);
browser = {};
if (matched.browser) {
browser[matched.browser] = true;
browser.version = matched.version;
}
// Chrome is Webkit, but Webkit is also Safari.
if (browser.chrome) {
browser.webkit = true;
} else if (browser.webkit) {
browser.safari = true;
}
jQuery.browser = browser;
}
If using jQuery version <1.9 ($.browser was removed in jQuery 1.9) use the following code instead:
$('.myClass').on('click', function (event) {
if ($.browser.msie) {
alert($.browser.version);
}
});

On my development machine I have three different versions of Oracle client software. I manage the tnsnames.ora
file in one of them. In the other two, I have entered in the tnsnames.ora
file:
ifile=path_to_tnsnames.ora_file/tnsnames.ora
This way, if for some reason the wrong tnsnames.ora
file is used by a client, it will always end up at the up-to-date version.

On Linux or MingW, with GNU toolchain:
ar -M <<EOM
CREATE libab.a
ADDLIB liba.a
ADDLIB libb.a
SAVE

ranlib libab.a
Of if you do not delete liba.a
and libb.a
, you can make a "thin archive":
ar crsT libab.a liba.a libb.a
On Windows, with MSVC toolchain:
lib.exe /OUT:libab.lib liba.lib libb.lib
if num in range(min, max):
"""do stuff..."""
else:

When you right click on a database and click Tasks
and then click Detach Database
, it brings up a dialog with the active connections.
By clicking on the hyperlink under "Messages" you can kill the active connections.
You can then kill those connections without detaching the database.

I will just repeat what @Ivo Bosticky said which can be overlooked. Put these lines at the VERY start of the py file.
import matplotlib
matplotlib.use('Agg')
Or one would get error
*/usr/lib/pymodules/python2.7/matplotlib/__init__.py:923: UserWarning: This call to matplotlib.use() has no effect because the the backend has already been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot,*

Kept having to return here to look up pg_get_viewdef
(how to remember that!!), so searched for a more memorable command... and got it:
\d+ viewname
You can see similar sorts of commands by typing \?
at the pgsql command line.
Bonus tip: The emacs command sql-postgres
makes pgsql a lot more pleasant (edit, copy, paste, command history).
I faced same problem because of low disk space. And partition which is hosting the ibdata1 file which is the system tablespace for the InnoDB infrastructure was full.

, or
:Let's first define a useful function to determine if something is executed or not. A simple function that accepts an argument, prints a message and returns the input, unchanged.
>>> def fun(i):
... print "executed"
... return i
...
One can observe the Python's short-circuiting behavior of and
, or
operators in the following example:
>>> fun(1)
executed
1
>>> 1 or fun(1) # due to short-circuiting "executed" not printed
1
>>> 1 and fun(1) # fun(1) called and "executed" printed
executed
1
>>> 0 and fun(1) # due to short-circuiting "executed" not printed
0
Note: The following values are considered by the interpreter to mean false:
False None 0 "" () [] {}
any()
, all()
:Python's any()
and all()
functions also support short-circuiting. As shown in the docs; they evaluate each element of a sequence in-order, until finding a result that allows an early exit in the evaluation. Consider examples below to understand both.
The function any()
checks if any element is True. It stops executing as soon as a True is encountered and returns True.
>>> any(fun(i) for i in [1, 2, 3, 4]) # bool(1) = True
executed
True
>>> any(fun(i) for i in [0, 2, 3, 4])
executed # bool(0) = False
executed # bool(2) = True
True
>>> any(fun(i) for i in [0, 0, 3, 4])
executed
executed
executed
True
The function all()
checks all elements are True and stops executing as soon as a False is encountered:
>>> all(fun(i) for i in [0, 0, 3, 4])
executed
False
>>> all(fun(i) for i in [1, 0, 3, 4])
executed
executed
False
Additionally, in Python
Comparisons can be chained arbitrarily; for example,
x < y <= z
is equivalent tox < y and y <= z
, except thaty
is evaluated only once (but in both casesz
is not evaluated at all whenx < y
is found to be false).
>>> 5 > 6 > fun(3) # same as: 5 > 6 and 6 > fun(3)
False # 5 > 6 is False so fun() not called and "executed" NOT printed
>>> 5 < 6 > fun(3) # 5 < 6 is True
executed # fun(3) called and "executed" printed
True
>>> 4 <= 6 > fun(7) # 4 <= 6 is True
executed # fun(3) called and "executed" printed
False
>>> 5 < fun(6) < 3 # only prints "executed" once
executed
False
>>> 5 < fun(6) and fun(6) < 3 # prints "executed" twice, because the second part executes it again
executed
executed
False
Edit:
One more interesting point to note :- Logical and
, or
operators in Python returns an operand's value instead of a Boolean (True
or False
). For example:
Operation
x and y
gives the resultif x is false, then x, else y
Unlike in other languages e.g. &&
, ||
operators in C that return either 0 or 1.
Examples:
>>> 3 and 5 # Second operand evaluated and returned
5
>>> 3 and ()
()
>>> () and 5 # Second operand NOT evaluated as first operand () is false
() # so first operand returned
Similarly or
operator return left most value for which bool(value)
== True
else right most false value (according to short-circuiting behavior), examples:
>>> 2 or 5 # left most operand bool(2) == True
2
>>> 0 or 5 # bool(0) == False and bool(5) == True
5
>>> 0 or ()
()
So, how is this useful? One example is given in Practical Python By Magnus Lie Hetland:
Let’s say a user is supposed to enter his or her name, but may opt to enter nothing, in which case you want to use the default value '<Unknown>'
.
You could use an if statement, but you could also state things very succinctly:
In [171]: name = raw_input('Enter Name: ') or '<Unknown>'
Enter Name:
In [172]: name
Out[172]: '<Unknown>'
In other words, if the return value from raw_input
is true (not an empty string), it is assigned to name (nothing changes); otherwise, the default '<Unknown>'
is assigned to name
.
Yes, you can. That should work.

Use images that are at least 1200 x 630 pixels for the best display on high resolution devices. At the minimum, you should use images that are 600 x 315 pixels to display link page posts with larger images. Images can be up to 8MB in size.
If your image is smaller than 600 x 315 px, it will still display in the link page post, but the size will be much smaller.
We've also redesigned link page posts so that the aspect ratio for images is the same across desktop and mobile News Feed. Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping.
The minimum image size is 200 x 200 pixels. If you try to use an image smaller than this you will see an error in the Sharing Debugger.
There are two different image sizes to use for game apps:
Open Graph Stories Images appear in a square format. Image ratios for these apps should be 600 x 600 px. Non-open Graph Stories Images appear in a rectangular format. You should use a 1.91:1 image ratio, such as 600 x 314 px.

Its quite a common misconception that you need a clear:both

PECS (Producer extends
and Consumer super
)
mnemonic ? Get and Put principle.
This principle states that:
extends
wildcard when you only get values out of a structure.super
wildcard when you only put values into a structure.Example in Java:
class Super {
Number testCoVariance() {
return null;
}
void testContraVariance(Number parameter) {
}
}
class Sub extends Super {
@Override
Integer testCoVariance() {
return null;
} //compiles successfully i.e. return type is don't care(Integer is subtype of Number)
@Override
void testContraVariance(Integer parameter) {
} //doesn't support even though Integer is subtype of Number
}
The Liskov Substitution Principle (LSP) states that “objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program”.
Within the type system of a programming language, a typing rule
To illustrate this general phenomenon, consider the array type. For the type Animal we can make the type Animal[]
Java Examples:
Object name= new String("prem"); //works
List<Number> numbers = new ArrayList<Integer>();//gets compile time error
Integer[] myInts = {1,2,3,4};
Number[] myNumber = myInts;
myNumber[0] = 3.14; //attempt of heap pollution i.e. at runtime gets java.lang.ArrayStoreException: java.lang.Double(we can fool compiler but not run-time)
List<String> list=new ArrayList<>();
list.add("prem");
List<Object> listObject=list; //Type mismatch: cannot convert from List<String> to List<Object> at Compiletime
bounded(i.e. heading toward somewhere) wildcard : There are 3 different flavours of wildcards:
?
or ? extends Object
- Unbounded Wildcard. It stands for the family of all types. Use when you both get and put.? extends T
(the family of all types that are subtypes of T
) - a wildcard with an upper bound. T
is the upper-most class in the inheritance hierarchy. Use an extends
wildcard when you only Get values out of a structure.? super T
( the family of all types that are supertypes of T
) - a wildcard with a lower bound. T
is the lower-most class in the inheritance hierarchy. Use a super
wildcard when you only Put values into a structure.Note: wildcard ?
means zero or one time, represents an unknown type. The wildcard can be used as the type of a parameter, never used as a type argument for a generic method invocation, a generic class instance creation.(i.e. when used wildcard that reference not used in elsewhere in program like we use T
)

Covariance and contravariance determine compatibility based on types. In either case, variance is a directed relation. Covariance can be translated as "different in the same direction," or with-different, whereas contravariance means "different in the opposite direction," or against-different. Covariant and contravariant types are not the same, but there is a correlation between them. The names imply the direction of the correlation.
The correct answer was already given "use parameters". Formatting a date and passing it as a string to SQL-Server can lead to errors as it depends on the settings how the date is interpreted on the server side. In europe, we write '1.12.2012' to indicate december 1st 2012, whereas in other countries this might be treated as january 12th.
When issuing statements directly in SSMS I use the format yyyymmdd
which seem to be quite general. I did not encounter any problems on the various installations I worked on so far.
There is another seldom used format, which is a bit weird but works for all versions:
select { d '2013-10-01' }
will return the first of october 2013.
select { ts '2013-10-01 13:45:01' }
will return october 1st, 1:45:01 PM
I strongly advice to use parameters and never format your own SQL code by pasting together homegrown formatted statement fragments. It is an entry for SQL injection and strange errors (formatting a float value is another potential issue)
Write to a file test.txt:
String filepath ="/mnt/sdcard/test.txt";
FileOutputStream fos = null;
try {
fos = new FileOutputStream(filepath);
byte[] buffer = "This will be writtent in test.txt".getBytes();
fos.write(buffer, 0, buffer.length);
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
You forgot to put z as an bind variable.
The following EXECUTE command runs a PL/SQL statement that references a stored procedure:
SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')
Note that the value returned by the stored procedure is being return into :Z
Just declare the variable at the starting of a class.
e.g. for string variable:
public partial class Login : System.Web.UI.Page
{
public string sError;
protected void Page_Load(object sender, EventArgs e)
{
//Page Load Code
}
try this.
var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
ipAddress = ip.ToString();
}
}
You can use regular expressions like this:
SELECT * FROM pet WHERE name REGEXP 'Bob|Smith';
The answer might very well depend on the compiler, so you probably want to edit your question (I mean, even the notion of segments is not mandated by ISO C nor ISO C++). For instance, on Windows an executable doesn't carry symbol names. One 'foo' would be offset 0x100, the other perhaps 0x2B0, and code from both translation units is compiled knowing the offsets for "their" foo.
I've created a little directive that bind with the tabindex attribute. It adds/removes the has-focus class dynamically.
@Directive({
selector: "[tabindex]"
})
export class TabindexDirective {
constructor(private elementHost: ElementRef) {}
@HostListener("focus")
setInputFocus(): void {
this.elementHost.nativeElement.classList.add("has-focus");
}
@HostListener("blur")
setInputFocusOut(): void {
this.elementHost.nativeElement.classList.remove("has-focus");
}
}
You could look into using BrowserStack: http://www.browserstack.com
While not free, it is rather cheap. It allows you to test against several iOS versions on both iPhone and iPad, along with Android, and various desktop browsers and OSs. It has proved quite invaluable to my workplace for doing just these sort of tests.
This can be caused by the two sides of the connection disagreeing over whether the connection timed out or not during a keepalive. (Your code tries to reused the connection just as the server is closing it because it has been idle for too long.) You should basically just retry the operation over a new connection. (I'm surprised your library doesn't do this automatically.)
Install Postman native app, Chrome extension has been deprecated. (Mine was opening in own window but still ran as Chrome app)
From my code, comparing to above solution, the simplest way is to define a layout which contains the fragment, then you could hide or unhide the fragment by controlling the layout attribute which is align with the general way of view. No additional code needed in this case and the additional deployment attributes of the fragment could be moved to the outer layout.
<LinearLayout style="@style/StHorizontalLinearView"
>
<fragment
android:layout_width="match_parent"
android:layout_height="390dp"
android:layout_alignParentTop="true"
/>
</LinearLayout>
The answer with most vote partially worked for me. The browser url stayed the same but my routerLinkActive
was not longer working after navigation.
My solution was to use lotation.go:
import { Component } from "@angular/core";
import { Location } from "@angular/common";
import { HttpParams } from "@angular/common/http";
export class whateverComponent {
constructor(private readonly location: Location, private readonly router: Router) {}
addQueryString() {
const params = new HttpParams();
params.append("param1", "value1");
params.append("param2", "value2");
this.location.go(this.router.url.split("?")[0], params.toString());
}
}
I used HttpParams to build the query string since I was already using it to send information with httpClient. but you can just build it yourself.
and the this._router.url.split("?")[0]
, is to remove all previous query string from current url.

I gave the table an id so I could find it. On onload (when the page is loaded by the browser), I set onclick event handlers to all rows of the table. Those handlers alert the content of the first cell.
<!DOCTYPE html>
<html>
<head>
<script>
var p = {
onload: function() {
var rows = document.getElementById("mytable").rows;
for(var i = 0, ceiling = rows.length; i < ceiling; i++) {
rows[i].onclick = function() {
alert(this.cells[0].innerHTML);
}
}
}
};
</script>
</head>
<body onload="p.onload()">
<table id="mytable">
<tr>
<td>0</td>
<td>row 1 cell 2</td>
</tr>
<tr>
<td>1</td>
<td>row 2 cell 2</td>
</tr>

Use suppressWarnings()
:
suppressWarnings(as.numeric(c("1", "2", "X")))
[1] 1 2 NA
This suppresses warnings.
You just missed an extra pair of brackets for the "OR" symbol. The following should do the trick:
([0-9]+)\s+((\bseconds\b)|(\bminutes\b))
Without those you were either matching a number followed by seconds OR just the word minutes
To add multiple columns and rows, we can also do a string concatenation. Not the best way, but it sure works.
var resultstring='<table>';
for(var j=0;j<arr.length;j++){
//array arr contains the field names in this case
resultstring+= '<th>'+ arr[j] + '</th>';
}
$(resultset).each(function(i, result) {
// resultset is in json format
resultstring+='<tr>';
for(var j=0;j<arr.length;j++){
resultstring+='<td>'+ result[arr[j]]+ '</td>';
}
resultstring+='</tr>';
});
resultstring+='</table>';
$('#resultdisplay').html(resultstring);
This also allows you to add rows and columns to the table dynamically, without hardcoding the fieldnames.
Step 1: First download the .msi i.e is the installation file from
https://www.mongodb.org/downloads#production
Step 2: Perform the installation using the so downloaded .msi file.Automatically it gets stored in program files. You could perform a custom installation and change the directory.
After this you should be able to see a Mongodb folder
Step 3: Create a new folder in this Mongodb folder with name 'data'. Create another new folder in your data directory with the name 'db'.
Step 4: Open cmd. Go to the directory where your mongodb folder exists and go to a path like C:\MongoDB\Server\3.0\bin. In the bin folder you should have mongodb.exe
Step 5: Now use
mongod --port 27017 --dbpath "C:\MongoDB\data\db"
-split outputs an array, and you can save it to a variable like this:
$a = -split 'Once upon a time'
$a[0]
Once
Another cute thing, you can have arrays on both sides of an assignment statement:
$a,$b,$c = -split 'Once upon a'
$c
a
The caTools
package has very fast rolling mean/min/max/sd and few other functions. I've only worked with runmean
and runsd
and they are the fastest of any of the other packages mentioned to date.
If you round 8.8333333333339 to 2 decimals, the correct answer is 8.83, not 8.84. The reason you got 8.83000000001 is because 8.83 is a number that cannot be correctly reprecented in binary, and it gives you the closest one. If you want to print it without all the zeros, do as VGE says:
print "%.2f" % 8.833333333339 #(Replace number with the variable?)
Add Web Reference is the old-style, deprecated ASP.NET webservices (ASMX) technology (using only the XmlSerializer for your stuff) - if you do this, you get an ASMX client for an ASMX web service. You can do this in just about any project (Web App, Web Site, Console App, Winforms - you name it).
Add Service Reference is the new way of doing it, adding a WCF service reference, which gives you a much more advanced, much more flexible service model than just plain old ASMX stuff.
Since you're not ready to move to WCF, you can also still add the old-style web reference, if you really must: when you do a "Add Service Reference", on the dialog that comes up, click on the [Advanced] button in the button left corner:
and on the next dialog that comes up, pick the [Add Web Reference] button at the bottom.
I liked the Xembly syntax, but it is not a statically typed API. You can get this with XMLBeam:
// Declare a projection
public interface Projection {
@XBWrite("/root/order/@id")
Projection setID(int id);
@XBWrite("/root/order")
Projection setValue(String value);
}
public static void main(String[] args) {
// create a projector
XBProjector projector = new XBProjector();
// use it to create a projection instance
Projection projection = projector.projectEmptyDocument(Projection.class);
// You get a fluent API, with java types in parameters
projection.setID(553).setValue("$140.00");
// Use the projector again to do IO stuff or create an XML-string
projector.toXMLString(projection);
}
My experience is that this works great even when the XML gets more complicated. You can just decouple the XML structure from your java code structure.
We copy/paste html pages from our ERP to Excel using "paste special.. as html/unicode" and it works quite well with tables.
To sum it all up, the correct answer is :
select * from db where Date >= '20100401' (Format of date yyyymmdd)
This will avoid any problem with other language systems and will use the index.
Prior to version 1.14, wget timeout arguments were not adhered to if downloading over https due to a bug.
With no doctype
tag, Chrome reports the same value for both calls.
Adding a strict doctype like <!DOCTYPE html>
causes the values to work as advertised.
The doctype
tag must be the very first thing in your document. E.g., you can't have any text before it, even if it doesn't render anything.
An easy fix for this is to float your H1 element left:
.centercol h1{
background: #F2EFE9;
border-left: 3px solid #C6C1B8;
color: #006BB6;
display: block;
float: left;
font-weight: normal;
font-size: 18px;
padding: 3px 3px 3px 6px;
}
I have put together a simple jsfiddle example that shows the effect of the "float: left" style on the width of your H1 element for anyone looking for a more generic answer:
You can also use CopyTo:
var ms = new MemoryStream();
yourStreamReader.BaseStream.CopyTo(ms); // blocking call till the end of the stream
ms.GetBuffer().CopyTo(yourArray, ms.Length);
or
var ms = new MemoryStream();
var ct = yourStreamReader.BaseStream.CopyToAsync(ms);
await ct;
ms.GetBuffer().CopyTo(yourArray, ms.Length);
I ran into the same error code when trying to install a Python module with pip. @Hackndo noted that the documentation indicate a security issue.
Based on that answer, my problem was solved by running the pip install command with sudo prefixed:
sudo pip install python-mpd2
really like keep things simple like this :)
$('input[type=file]').wrap('<form></form>').parent().trigger('reset').children().unwrap('<form></form>');
You can do that using at. You can try out the following simple example:
const size_t N = 20;
std::vector<int> vec(N);
try {
vec.at(N - 1) = 7;
} catch (std::out_of_range ex) {
std::cout << ex.what() << std::endl;
}
assert(vec.at(N - 1) == 7);
Notice that method at
returns an allocator_type::reference
, which is that case is a int&
. Using at
is equivalent to assigning values like vec[i]=...
.
There is a difference between at
and insert as it can be understood with the following example:
const size_t N = 8;
std::vector<int> vec(N);
for (size_t i = 0; i<5; i++){
vec[i] = i + 1;
}
vec.insert(vec.begin()+2, 10);
If we now print out vec
we will get:
1 2 10 3 4 5 0 0 0
If, instead, we did vec.at(2) = 10
, or vec[2]=10
, we would get
1 2 10 4 5 0 0 0

It is not strange for me that none of the solutions above came up, but I saw how the igd installation removed the new version and installed the old one, for the solution I downloaded this archive:https://pypi.org/project/igd/#files
and changed the recommended version of the new version: 'lxml==4.3.0' in setup.py It works!
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2010-07-14 09:00:02");

I can't find a single reference that state that it's possible without involving the serverside.
MSDN on:
From browserLanguage:
In Microsoft Internet Explorer 4.0 and earlier, the browserLanguage property reflects the language of the installed browser's user interface. For example, if you install a Japanese version of Windows Internet Explorer on an English operating system, browserLanguage would be ja.
In Internet Explorer 5 and later, however, the browserLanguage property reflects the language of the operating system regardless of the installed language version of Internet Explorer. However, if Microsoft Windows 2000 MultiLanguage version is installed, the browserLanguage property indicates the language set in the operating system's current menus and dialogs, as found in the Regional Options of the Control Panel. For example, if you install a Japanese version of Internet Explorer 5 on an English (United Kingdom) operating system, browserLanguage would be en-gb. If you install Windows 2000 MultiLanguage version and set the language of the menus and dialogs to French, browserLanguage would be fr, even though you have a Japanese version of Internet Explorer.
Note This property does not indicate the language or languages set by the user in Language Preferences, located in the Internet Options dialog box.
Furthermore, it looks like browserLanguage
is deprecated cause IE8 doesn't list it

Check that your singing identity IN YOUR TARGET properties is correct. This one over-rides what you have in your project properties.
Also: I dunno if this is true - but I wasn't getting emails detailing my binary rejections when I did the "ready for binary upload" from a PC - but I DID get an email when I did this on the MAC

First there are two variations on how the xml can be written:
<row>
<IdInvernadero>8</IdInvernadero>
<IdProducto>3</IdProducto>
<IdCaracteristica1>8</IdCaracteristica1>
<IdCaracteristica2>8</IdCaracteristica2>
<Cantidad>25</Cantidad>
<Folio>4568457</Folio>
</row>
<row>
<IdInvernadero>3</IdInvernadero>
<IdProducto>3</IdProducto>
<IdCaracteristica1>1</IdCaracteristica1>
<IdCaracteristica2>2</IdCaracteristica2>
<Cantidad>72</Cantidad>
<Folio>4568457</Folio>
</row>
Answer:
SELECT
Tbl.Col.value('IdInvernadero[1]', 'smallint'),
Tbl.Col.value('IdProducto[1]', 'smallint'),
Tbl.Col.value('IdCaracteristica1[1]', 'smallint'),
Tbl.Col.value('IdCaracteristica2[1]', 'smallint'),

You really don't need jQuery for this.
var myarr = ["I", "like", "turtles"];
var arraycontainsturtles = (myarr.indexOf("turtles") > -1);
Hint: indexOf returns a number, representing the position where the specified searchvalue occurs for the first time, or -1 if it never occurs
or
function arrayContains(needle, arrhaystack)
{
return (arrhaystack.indexOf(needle) > -1);
}
It's worth noting that array.indexOf(..)
is not supported in IE < 9, but jQuery's indexOf(...)
function will work even for those older versions.
For me, inspecting the solution gave me hundreds of errors, including many "cannot find file in search paths". I tried every suggestion out there to fix it and none of them worked. I ended up finding out inspecting the project, instead of the solution, worked perfectly.

For converting date to string check this thread
Convert java.util.Date to String
And for converting string to date try this,
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class StringToDate
{
public static void main(String[] args) throws ParseException
{
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
String strDate = "14/03/2003 08:05:10";
System.out.println("Date - " + sdf.parse(strDate));

I'm on Linux Mint 19 (Ubuntu 18 based). I wanted to have coredump
files in current folder. I had to do two things:
/proc/sys/kernel/core_pattern
(by # echo "core.%p.%s.%c.%d.%P > /proc/sys/kernel/core_pattern
or by # sysctl -w kernel.core_pattern=core.%p.%s.%c.%d.%P)
$ ulimit -c unlimited
That was written already in the answers, but I wrote to summarize succinctly. Interestingly changing limit did not require root privileges (as per https://askubuntu.com/questions/162229/how-do-i-increase-the-open-files-limit-for-a-non-root-user non-root can only lower the limit, so that was unexpected - comments about it are welcome).
For instance you can use
update tablename set datetimefield='19980223 14:23:05'
update tablename set datetimefield='02/23/1998 14:23:05'
update tablename set datetimefield='1998-12-23 14:23:05'
update tablename set datetimefield='23 February 1998 14:23:05'
update tablename set datetimefield='1998-02-23T14:23:05'
You need to be careful of day/month order since this will be language dependent when the year is not specified first. If you specify the year first then there is no problem; date order will always be year-month-day.
Try Below Simple Ruby Magics :)
(1..x).each { |n| puts n }
x.times { |n| puts n }
1.upto(x) { |n| print n }
Read carefully the warning message :
The POM for org.raml:jaxrs-code-generator:jar:2.0.0 is missing, no dependency information available
The problem is not the jar, but the pom.xml that is missing.
The pom.xml lists the required dependencies for this jar that Maven will pull during the build and overall the packaging of your application.
So, you may really need it.
Note that this problem may of course occur for other Maven dependencies and the ideas to solve that is always the same.
The Mule website documents very well that in addition to some information related to.
1) Quick workaround : looking for in the internet the pom.xml
of the artifact
Googling the artifact id, the group id and its version gives generally
interesting results : maven repository links to download it.
In the case of the org.raml:jaxrs-code-generator:jar:2.0.0
dependency, you can download the pom.xml
from the Maven mule repository :
2) Clean workaround for a single Maven project : adding the repository declaration in your pom.
In your case, add the Maven mule repositories :
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
...
<repositories>
<repository>
<id>mulesoft-releases</id>
<name>MuleSoft Repository</name>

<id>mulesoft-snapshots</id>
<name>MuleSoft Snapshot Repository</name>
<url>http://repository.mulesoft.org/snapshots/</url>
<layout>default</layout>
</repository>
</repositories>
...
</project>
3) Clean workaround for any Maven projects : add the repository declaration in your settings.xml
<profile>
<repositories>
...
<repository>
<id>mulesoft-releases</id>
<name>MuleSoft Repository</name>
<url>http://repository.mulesoft.org/releases/</url>

Note that in some rare cases, the pom.xml
declaring the dependencies is nowhere. So, you have to identify yourself whether the artifact requires dependencies.
function openLinkNewTab (url){
$('body').append('<a id="openLinkNewTab" href="' + url + '" target="_blank"><span></span></a>').find('#openLinkNewTab span').click().remove();
}
@PropertySource
only supports properties files (it's a limitation from Spring, not Boot itself). Feel free to open a feature request ticket in JIRA.
I have tried to install the missing packages. Installing the toolchain and restarting CLion solved all in my case:
pacman -S mingw-w64-x86_64-cmake mingw-w64-x86_64-extra-cmake-modules
pacman -S mingw-w64-x86_64-make
pacman -S mingw-w64-x86_64-gdb
pacman -S mingw-w64-x86_64-toolchain
Neither clean/reset/hard checkout/rebase worked for me.
So I just removed files that git complained about*
rm /path/to/files/that/git/complained/about
*I checked if this files can be removed by checking out a brand new repo in a separate folder (files were not there)
I had exactly the same issue: was cleaning up my folders, rearranging and moving files. I entered: git rm . and hit enter; and then felt my bowels loosen a bit. Luckily, I didn't type in git commit -m "" straightaway.
However, the following command
git checkout .
restored everything, and saved my life.
This is simple and meaningful reverse function, easy to understand and code
def reverse_sentence(text):
words = text.split(" ")
reverse =""
for word in reversed(words):
reverse += word+ " "
return reverse
I think Piko means in his response that there is the hbm file. I have a file called Tax.java. The mapping information are saved in the hbm (=hibernate mapping) file. In the class tag there is a property called lazy. Set that property to true. The following hbm example shows a way to set the lazy property to false.
` id ...'
If you are using Annotations instead look in the hibernate documenation. http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/
I hope that helped.
If you use the vim plugin https://github.com/tpope/vim-surround (or use VSCode Vim plugin, which comes with vim-surround pre-installed), its pretty convinient!
add
ysiw' // surround in word `'`
drop
ds' // drop surround `'`
change
cs'" // change surround from `'` to `"`
It even works for html tags!
cst<em> // change surround from current tag to `<em>`
check out the readme on github for better examples
Being specific about this keeps you away from the whole TRUE in VB is -1 and in other langauges true is just NON ZERO. Keeping the boolean field as true or false keeps java outside of this argument.
You can add extra data with form data
use serializeArray and add the additional data:
var data = $('#myForm').serializeArray();
data.push({name: 'tienn2t', value: 'love'});
$.ajax({
type: "POST",
url: "your url.php",
data: data,
dataType: "json",
success: function(data) {
//var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
// do what ever you want with the server response
},
error: function() {
alert('error handing here');
}
});
Having 2 scripts called test.bat and ping.bat in same folder:
Script test.bat contains one line:
ping google.com
Script ping.bat contains below lines:
@echo off
echo Hello!
pause
Executing "test.bat" the result on CMD will be:
Hello!
Press any key to continue . . .
Why? Because "test.bat" is calling the "ping.bat" ("ping google.com" is interpreted as calling the "ping.bat" script). Same is happening if script "ping.bat" contains "ping google.com". The script will execute himself in a loop.
Easy ways to avoid this:
- Do not name your script "ping.bat".
- You can name the script as "ping.bat" but inside the script use "ping.exe google.com" instead of "ping google.com".
This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.
Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.
In this case I'd ask why you're including both cstdlib
and stdlib.h
; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib
puts them in the namespace std
in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!
Anyway, your use of using namespace std
(which I would recommend against, in future) means that std::system
from cstdlib
now conflicts with system
from stdlib.h
. I can't explain what's going on with std::cout
and std::cin
.
Try removing #include <stdlib.h>
and see what happens.
If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.
When you create a new File
, you are supposed to provide the file name, not only the directory you want to put your file in.
Try with something like
File file = new File("D:/Data/" + item.getFileName());
So the package will be downloaded in a temp folder C:\Users\U122337.BOSTONADVISORS\AppData\Local\Temp\Rtmp404t8Y\downloaded_packages from where it will be installed into your library folder, e.g. C:\R\library\zoo
What you have to do once install command is done: Open Packages menu -> Load package...
You will see your package on the list. You can automate this: How to load packages in R automatically?
add your script tag on the bottom of the body tag. so that script loads after html content then you won't get such error and add=
&&
means "and if successful"; by placing your if
statement on the right-hand side of it, you ensure that it will only run if grep
returns 0
. To fix it, use ;
instead:
ps aux | grep some_proces[s] > /tmp/test.txt ; if [ $? -eq 0 ]; then echo 1; else echo 0; fi
(or just use a line-break).
You need to add your ORACLE_HOME
definition in your listener.ora file. Right now its not registered with any ORACLE_HOME
.
Sample listener.ora
abc =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abc.kma.com)(PORT = 1521))
)
)
SID_LIST_abc =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME= /abc/DbTier/11.2.0)
(SID_NAME = abc)
)
)
For me, it only worked when I added the following line of code
$('#target').val($('#target').find("option:first").val());
Actually, ANDROID_ID on 2.2 always equals 9774D56D682E549C (according to this thread + my own experiments).
So, you could check something like this:
String androidID = ...;
if(androidID == null || androidID.equals("9774D56D682E549C"))
do stuff;
Not the prettiest, but it does the job.
Some terminals allow to print colored text. Some colors look like if they are "bold". Try:
print ('\033[1;37mciao!')
The sequence '\033[1;37m' makes some terminals to start printing in "bright white" that may look a bit like bolded white. '\033[0;0m' will turn it off.
