There is RIPS - A static source code analyser for vulnerabilities in PHP scripts. The source code of RIPS is available at SourceForge.
From the RIPS site:
RIPS is a tool written in PHP to find vulnerabilities in PHP applications using static code analysis. By tokenizing and parsing all source code files RIPS is able to transform PHP source code into a program model and to detect sensitive sinks (potentially vulnerable functions) that can be tainted by userinput (influenced by a malicious user) during the program flow. Besides the structured output of found vulnerabilities RIPS also offers an integrated code audit framework for further manual analysis.
Optimyth Software has just launched a static analysis service in the cloud www.checkinginthecloud.com. Just securely upload your code run the analysis and get the results. No hassles.
It supports several languages including C# more info can be found at wwww.optimyth.com
Use this function to check if a string is alphanumeric:
public boolean isAlphanumeric(String str)
{
char[] charArray = str.toCharArray();
for(char c:charArray)
{
if (!Character.isLetterOrDigit(c))
return false;
}
return true;
}
It saves having to import external libraries and the code can easily be modified should you later wish to perform different validation checks on strings.
For most cases (long for floats, long long for double and long double):
long a{ std::lround(1.5f) }; //2l
long long b{ std::llround(std::floor(1.5)) }; //1ll
I really liked Maurius' explanation (highest upvoted response) with the three different methods for calling setTimeout
.
In my code I want to automatically auto-navigate to the previous page upon completion of an AJAX save event. The completion of the save event has a slight animation in the CSS indicating the save was successful.
In my code I found a difference between the first two examples:
setTimeout(window.history.back(), 3000);
This one does not wait for the timeout--the back() is called almost immediately no matter what number I put in for the delay.
However, changing this to:
setTimeout(function() {window.history.back()}, 3000);
This does exactly what I was hoping.
This is not specific to the back() operation, the same happens with alert()
. Basically with the alert()
used in the first case, the delay time is ignored. When I dismiss the popup the animation for the CSS continues.
Thus, I would recommend the second or third method he describes even if you are using built in functions and not using arguments.
If you want to see what is run in the database use dd(DB::getQueryLog())
to see what queries were run.
Try this
BookingDates::where('email', Input::get('email'))
->orWhere('name', 'like', '%' . Input::get('name') . '%')->get();
utf8_bin
compares the bits blindly. No case folding, no accent stripping.utf8_general_ci
compares one byte with one byte. It does case folding and accent stripping, but no 2-character comparisions: ij
is not equal ?
in this collation.utf8_*_ci
is a set of language-specific rules, but otherwise like unicode_ci
. Some special cases: Ç
, C
, ch
, ll
utf8_unicode_ci
follows an old Unicode standard for comparisons. ij
=?
, but ae
!= æ
utf8_unicode_520_ci
follows an newer Unicode standard. ae
= æ
See collation chart for details on what is equal to what in various utf8 collations.
utf8
, as defined by MySQL is limited to the 1- to 3-byte utf8 codes. This leaves out Emoji and some of Chinese. So you should really switch to utf8mb4
if you want to go much beyond Europe.
The above points apply to utf8mb4
, after suitable spelling change. Going forward, utf8mb4
and utf8mb4_unicode_520_ci
are preferred.
I had a similar problem just now!
You can use the filter_input()
function with FILTER_VALIDATE_INT
and FILTER_NULL_ON_FAILURE
to filter only integer values out of the $_GET
variable. Works pretty accurately! :)
Check out my question here: How to check whether a variable in $_GET Array is an integer?
By using the requestInterceptor, it worked for me:
const ui = SwaggerUIBundle({
...
requestInterceptor: (req) => {
req.headers.Authorization = "Bearer " + req.headers.Authorization;
return req;
},
...
});
The whole idea around semantic markup is the separation of markup and presentation, which includes layout.
Div's aren't replacing tables, they have their own use in separating content into blocks of related content (, ). When you don't have the skills and are relying on tables, you'll often have to separate your content in to cells in order to get the desired layout, but you wont need to touch the markup to achieve presentation when using semantic markup. This is really important when the markup is being generated rather than static pages.
Developers need to stop providing markup that implies layout so that those of us who do have the skills to present content can get on with our jobs, and developers don't have to come back to their code to make changes when presentation needs change.

Since you are not allowed to put more than two conditions in one condition group (And | Or) you have to create an extra nested group (MSDN). The expression A AND B AND C
looks like this:
<And>
A
<And>
B
C
</And>
</And>

You can also just add the authorization header yourself.
Just make the name "Authorization" and the value "Basic BASE64({USERNAME:PASSWORD})"
String username = "abc";
String password = "123";
String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(username + ":" + password));
httpWebRequest.Headers.Add("Authorization", "Basic " + encoded);
Switched the encoding from UTF-8 to ISO 8859-1 per What encoding should I use for HTTP Basic Authentication? and Jeroen's comment.
I've noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error:
String cannot be resolved to a variable
With this Java code:
if (true)
String my_variable = "somevalue";
System.out.println("foobar");
You would think this code is very straight forward, the conditional is true, we set my_variable to somevalue. And it should print foobar. Right?
Wrong, you get the above mentioned compile time error. Eclipse is trying to prevent you from making a mistake by assuming that both statements are within the if statement.
If you put braces around the conditional block like this:
if (true){
String my_variable = "somevalue"; }
System.out.println("foobar");
Then it compiles and runs fine. Apparently poorly bracketed conditionals are fair game for generating compile time errors now.
For mobiles, it’s better to use it
canvas.width = document.documentElement.clientWidth;
canvas.height = document.documentElement.clientHeight;
because it will display incorrectly after changing the orientation.The “viewport” will be increased when changing the orientation to portrait.See full example
Depending on the file which will be put into filesystem, as long as that file is not a malware, then that would be safe.
But don't worry to write/read file(s) to File System directory, cause you can tighten that directory security (include it's inheritance) by give a proper access right and security restriction. eg: read/write/modify.
By default, File System, Local Storage, and Storage directory are located on "\Users[Current User]\AppData\Local\Google\Chrome\User Data\Default" directory.
However you can customize it by using "--user-data-dir" flag.
And this is a sample:
"C:\Program Files (x86)\Google\Application\chrome.exe" --user-data-dir="C:\Chrome_Data\OO7" --allow-file-access-from-files
Hope this helps anyone.
Simply, the "Real Time" priority class is higher than "High" priority class. I don't think there's much more to it than that. Oh yeah - you have to have the SeIncreaseBasePriorityPrivilege
to put a thread into the Real Time class.
Windows will sometimes boost the priority of a thread for various reasons, but it won't boost the priority of a thread into another priority class. It also won't boost the priority of threads in the real-time priority class. So a High priority thread won't get any automatic temporary boost into the Real Time priority class.
Russinovich's "Inside Windows" chapter on how Windows handles priorities is a great resource for learning how this works:
Note that there's absolutely no problem with a thread having a Real-time priority on a normal Windows system - they aren't necessarily for special processes running on dedicatd machines. I imagine that multimedia drivers and/or processes might need threads with a real-time priority. However, such a thread should not require much CPU - it should be blocking most of the time in order for normal system events to get processing.
If you are using Twig in your application as a component you can do this:
$twig = new Twig_Environment($loader, array(
'autoescape' => false
));
$twig->addFilter('var_dump', new Twig_Filter_Function('var_dump'));
Then in your templates:
{{ my_variable | var_dump }}
your understanding is right. For detailed info on {} see bash ref - parameter expansion
'for' and 'while' have different syntax and offer different styles of programmer control for an iteration. Most non-asm languages offer a similar syntax.
With while, you would probably write i=0; while [ $i -lt 10 ]; do echo $i; i=$(( i + 1 )); done
in essence manage everything about the iteration yourself
You can use this library, which both initially sizes your iframe correctly and also keeps it at the right size by detecting whenever the size of the iframe's content changes (either via regular checking in a setInterval
or via MutationObserver
) and resizing it.

You can save it as .txt and change it manually using a mouse click and your keyboard. OR, when saving the file:

field.File name
fieldIn Oracle, (+) denotes the "optional" table in the JOIN. So in your query,
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id(+)
it's a LEFT OUTER JOIN of table 'b' to table 'a'. It will return all data of table 'a' without losing its data when the other side (optional table 'b') has no data.
The modern standard syntax for the same query would be
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b ON a.id=b.id
or with a shorthand for a.id=b.id
(not supported by all databases):
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b USING(id)
Older syntax, in both Oracle and other databases:
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id
More modern syntax:
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a
INNER JOIN b ON a.id=b.id
Or simply:
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a
JOIN b ON a.id=b.id
It will only return all data where both 'a' & 'b' tables 'id' value is same, means common part.
This is just the same as a LEFT JOIN, but switches which table is optional.
Old Oracle syntax:
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id(+)=b.id
Modern standard syntax:
SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a
RIGHT JOIN b ON a.id=b.id

The following code may help you:
$("#svgEuropa [id='stallwanger.it.dev_shape_DEU']").on("click",function(){
alert($(this).attr("id"));
});
var parsedData;
try {
parsedData = JSON.parse(data)
} catch (e) {
// is not a valid JSON string
}
However, I will suggest to you that your http call / service should return always a data in the same format. So if you have an error, than you should have a JSON object that wrap this error:
{"error" : { "code" : 123, "message" : "Foo not supported" } }
And maybe use as well as HTTP status a 5xx code.
To maintain a responsive image while still enforcing the image to have a certain aspect ratio you can do the following:
HTML:
<div class="ratio2-1">
<img src="../image.png" alt="image">
</div>
And SCSS:
.ratio2-1 {
overflow: hidden;
position: relative;
&:before {
content: '';
display: block;
padding-top: 50%; // ratio 2:1
}
img {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
}
This can be used to enforce a certain aspect ratio, regardless of the size of the image that authors upload.
Thanks to @Kseso at http://codepen.io/Kseso/pen/bfdhg. Check this URL for more ratios and a working example.

Try Dijkstra's algorithm on the following graph, assuming A
is the source node and D
is the destination, to see what is happening:
Note that you have to follow strictly the algorithm definition and you should not follow your intuition (which tells you the upper path is shorter).
The main insight here is that the algorithm only looks at all directly connected edges and it takes the smallest of these edge. The algorithm does not look ahead. You can modify this behavior , but then it is not the Dijkstra algorithm anymore.
Some might find my function useful if you just want to print out all of the tables and columns in your db.
In the loop, I query each TABLE with LIMIT 0 so it just returns the header info without all the data. You make an empty df out of it, and use the iterable df.columns to print each column name out.
conn = sqlite3.connect('example.db')
c = conn.cursor()
def table_info(c, conn):
'''
prints out all of the columns of every table in db
c : cursor object
conn : database connection object
'''
tables = c.execute("SELECT name FROM sqlite_master WHERE type='table';").fetchall()
for table_name in tables:
table_name = table_name[0] # tables is a list of single item tuples
table = pd.read_sql_query("SELECT * from {} LIMIT 0".format(table_name), conn)
print(table_name)
for col in table.columns:
print('\t-' + col)
print()
table_info(c, conn)
Results will be:
table1
-column1
-column2
table2
-column1
-column2
-column3
etc.

Same answer as above, but with async await
and ready to use!
const fs = require('fs/promises');
const path = require('path');
async function isExists(path) {
try {
await fs.access(path);
return true;
} catch {
return false;
}
};
async function writeFile(filePath, data) {
try {
const dirname = path.dirname(filePath);
const exist = await isExists(dirname);
if (!exist) {
await fs.mkdir(dirname, {recursive: true});
}
await fs.writeFile(filePath, data, 'utf8');
} catch (err) {
throw new Error(err);
}
}
Example:
(async () {
const data = 'Hello, World!';
await writeFile('dist/posts/hello-world.html', data);
})();
In the opening tag of your form, set an action attribute like so:
<form id="contactForm" action="#">
If you take a look at @types/node-fetch you will see the body definition
export class Body {
bodyUsed: boolean;
body: NodeJS.ReadableStream;
json(): Promise<any>;
json<T>(): Promise<T>;
text(): Promise<string>;
buffer(): Promise<Buffer>;
}
That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:
import { Actor } from './models/actor';
fetch(`http://swapi.co/api/people/1/`)
.then(res => res.json<Actor>())
.then(res => {
let b:Actor = res;
});

Here are couple ways of doing it:
>>> t = ((1, 'a'), (2, 'b'))
>>> # using reversed function
>>> dict(reversed(i) for i in t)
{'a': 1, 'b': 2}
>>> # using slice operator
>>> dict(i[::-1] for i in t)
{'a': 1, 'b': 2}

md5sum
puts backslash before hash if there is backslash in file name. First 32 characters or anything before first space may not be a proper hash. It will not happen when using standard input (file name will be just -), so pixelbeat's answer will work, but many others will require adding something like | tail -c 32
.
I have tried almost every obfuscator on the market and SmartAssembly is the best in my opinion.
Do something like this:
typedef std::map<std::string, std::string> InnerMap;
typedef std::map<std::string, InnerMap> OuterMap;
Outermap mm;
...//set the initial values
for (OuterMap::iterator i = mm.begin(); i != mm.end(); ++i) {
InnerMap &im = i->second;
for (InnerMap::iterator ii = im.begin(); ii != im.end(); ++ii) {
std::cout << "map["
<< i->first
<< "]["
<< ii->first
<< "] ="
<< ii->second
<< '\n';
}
}
AFAIK you will need at least a little bit of JavaScript...
I would suggest to use jQuery.
You can include this library in one line. And then you can access your div with
$('div').click(function(){
// do stuff here
});
and respond to the click event.
macro-less and portable way to declare one or more parameters as unused:

use DATE_DIFF
Select I.Fee

Often you will want to specify a manifest, like so:
jar -cvfm myJar.jar myManifest.txt myApp.class
Which reads: "create verbose jarFilename manifestFilename", followed by the files you want to include. Verbose means print messages about what it's doing.
Note that the name of the manifest file you supply can be anything, as jar
will automatically rename it and put it into the right directory within the jar file.

I have come across this error when the app resides on a network share, and the device (laptop, tablet, ...) becomes disconnected from the network while the app is in use. In my case, it was due to a Surface tablet going out of wireless range. No problems after installing a better WAP.

If your input was structured as XML, you could use the importXML
function. (More info here at quirksmode).
If it isn't XML, and there isn't an equivalent function for importing plain text, then you could open it in a hidden iframe and then read the contents from there.
Here goes a bunch of different ways to get the ID, including Scope_Identity:
Stack memory allocation (function variables, local variables) can be problematic when your stack is too "deep" and you overflow the memory available to stack allocations. The heap is for objects that need to be accessed from multiple threads or throughout the program lifecycle. You can write an entire program without using the heap.
You can leak memory quite easily without a garbage collector, but you can also dictate when objects and memory is freed. I have run in to issues with Java when it runs the GC and I have a real time process, because the GC is an exclusive thread (nothing else can run). So if performance is critical and you can guarantee there are no leaked objects, not using a GC is very helpful. Otherwise it just makes you hate life when your application consumes memory and you have to track down the source of a leak.
As other have answered, the result is exactly the same, None
is returned in all cases.
The difference is stylistic, but please note that PEP8 requires the use to be consistent:
Be consistent in return statements. Either all return statements in a function should return an expression, or none of them should. If any return statement returns an expression, any return statements where no value is returned should explicitly state this as return None, and an explicit return statement should be present at the end of the function (if reachable).
Yes:
def foo(x): if x >= 0: return math.sqrt(x) else: return None def bar(x): if x < 0: return None return math.sqrt(x)
No:
def foo(x): if x >= 0: return math.sqrt(x) def bar(x): if x < 0: return return math.sqrt(x)
https://www.python.org/dev/peps/pep-0008/#programming-recommendations
Basically, if you ever return non-None
value in a function, it means the return value has meaning and is meant to be caught by callers. So when you return None
, it must also be explicit, to convey None
in this case has meaning, it is one of the possible return values.
If you don't need return at all, you function basically works as a procedure instead of a function, so just don't include the return
statement.
If you are writing a procedure-like function and there is an opportunity to return earlier (i.e. you are already done at that point and don't need to execute the remaining of the function) you may use empty an return
s to signal for the reader it is just an early finish of execution and the None
value returned implicitly doesn't have any meaning and is not meant to be caught (the procedure-like function always returns None
anyway).
Alternately, you can start a program containing the line with one click.

It looks like your syntax for unset is invalid, and the lack of reindexing might cause trouble in the future. See: the section on PHP arrays.
The correct syntax is shown above. Also keep in mind array-values for reindexing, so you don't ever index something you previously deleted.
You have to use cin.getline()

This little class never gives me any problem, just extend it and use the copy() method:
import simplejson as json
class BlindCopy(object):
def copy(self, json_str):
dic = json.loads(json_str)
for k, v in dic.iteritems():
if hasattr(self, k):
setattr(self, k, v);
You can also use an optional extension so you don't have to worry about unwrapping or using == true
:
extension String {
var isBlank: Bool {
return self.trimmingCharacters(in: .whitespacesAndNewlines).isEmpty
}
}
extension Optional where Wrapped == String {
var isBlank: Bool {
if let unwrapped = self {
return unwrapped.isBlank
} else {
return true
}
}
}
Note: when calling this on an optional, make sure not to use ?
or else it will still require unwrapping.
This is a generic solution for your problem and others related.

2. Create a Protocol with your desire behavior, for your specific case will be portrait.
protocol orientationIsOnlyPortrait {}
Nota: If you want, add it in the top of UIHelper Class.
3. Extend your View Controller
In your case:
class Any_ViewController: UIViewController,orientationIsOnlyPortrait {
....
}
4. In app delegate class add this method:
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
let presentedViewController = UIHelper.topViewController()
if presentedViewController is orientationIsOnlyPortrait {
return .portrait
}
return .all
}
Final Notes:
You need to add a reference to System.Drawing.dll
.
As mentioned in the comments below this can be done as follows: In your Solution Explorer (Where all the files are shown with your project), right click the "References" folder and find System.Drawing on the .NET Tab.
Add this attribute to you activity in manifest file. android:noHistory="true"
return numberString.TrimStart('0');
If you are using Entity Framework like me, you should define Time out on Startup class as follows:
services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"), o => o.CommandTimeout(180)));
All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)
Based on this related answer, you are looking at a list that looks like: A-Z
, a-z
, 0-9
, -
, .
, _
, ~
, :
, /
, ?
, #
, [
, ]
, @
, !
, $
, &
, '
, (
, )
, *
, +
, ,
, ;
, %
, and =
. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. %
can only be used in conjunction with url encoding as in %20
), the RFC has all of these specifics.
Type in "netstat -ano" into your command line. I saw that it was showing something for Local Address port 0.0.0.0:80.
My issue was because I had SQL Server Reporting Services on Port 80. So I followed these instructions and changed the port # from 80 to 81:
Here is a picture of my command line after I changed the port number for SQL Server Reporting Services:
If you are still having the same issue, read this forum:
Using zip function we can get both element and index.

revalidate
is called on a container once new components are added or old ones removed. this call is an instruction to tell the layout manager to reset based on the new component list. revalidate
will trigger a call to repaint what the component thinks are 'dirty regions.' Obviously not all of the regions on your JPanel
are considered dirty by the RepaintManager
.
repaint
is used to tell a component to repaint itself. It is often the case that you need to call this in order to cleanup conditions such as yours.
Its true the official documentation (Apache log4net™ Manual - Introduction) states there are the following levels...
... but oddly when I view assembly log4net.dll, v1.2.15.0 sealed class log4net.Core.Level I see the following levels defined...
public static readonly Level Alert;
public static readonly Level All;
public static readonly Level Critical;
public static readonly Level Debug;
public static readonly Level Emergency;
public static readonly Level Error;
public static readonly Level Fatal;
public static readonly Level Fine;
public static readonly Level Finer;
public static readonly Level Finest;
public static readonly Level Info;
public static readonly Level Log4Net_Debug;
public static readonly Level Notice;
public static readonly Level Off;
public static readonly Level Severe;
public static readonly Level Trace;
public static readonly Level Verbose;
public static readonly Level Warn;
I have been using TRACE in conjunction with PostSharp OnBoundaryEntry and OnBoundaryExit for a long time. I wonder why these other levels are not in the documentation. Furthermore, what is the true priority of all these levels?
Mathematically, to get percentage from two numbers:
percentage = (yourNumber / totalNumber) * 100;
And also, to calculate from a percentage :
number = (percentage / 100) * totalNumber;
I use the --user option to uninstall all the packages installed in the user site.
pip3 freeze --user | xargs pip3 uninstall -y
I also faced the same problem and figured the problem was happening as the layout_width of the TextView was having wrap_content. You need to have layout_width as match_parent and the android:gravity = "gravity"
Conceptually, an interface is used to formally and semi-formally define a set of methods that an object will provide. Formally means a set of method names and signatures, and semi-formally means human readable documentation associated with those methods.
Interfaces are only descriptions of an API (after all, API stands for application programming interface), they can't contain any implementation, and it's not possible to use or run an interface. They only make explicit the contract of how you should interact with an object.
Classes provide an implementation, and they can declare that they implement zero, one or more Interfaces. If a class is intended to be inherited, the convention is to prefix the class name with "Base".
There is a distinction between a base class and an abstract base classes (ABC). ABCs mix interface and implementation together. Abstract outside of computer programming means "summary", that is "abstract == interface". An abstract base class can then describe both an interface, as well as an empty, partial or complete implementation that is intended to be inherited.
Opinions on when to use interfaces versus abstract base classes versus just classes is going to vary wildly based on both what you are developing, and which language you are developing in. Interfaces are often associated only with statically typed languages such as Java or C#, but dynamically typed languages can also have interfaces and abstract base classes. In Python for example, the distinction is made clear between a Class, which declares that it implements an interface, and an object, which is an instance of a class, and is said to provide that interface. It's possible in a dynamic language that two objects that are both instances of the same class, can declare that they provide completely different interfaces. In Python this is only possible for object attributes, while methods are shared state between all objects of a class. However, in Ruby, objects can have per-instance methods, so it's possible that the interface between two objects of the same class can vary as much as the programmer desires (however, Ruby doesn't have any explicit way of declaring Interfaces).
In dynamic languages the interface to an object is often implicitly assumed, either by introspecting an object and asking it what methods it provides (look before you leap) or preferably by simply attempting to use the desired interface on an object and catching exceptions if the object doesn't provide that interface (easier to ask forgiveness than permission). This can lead to "false positives" where two interfaces have the same method name, but are semantically different. However, the trade-off is that your code is more flexible since you don't need to over specify up-front to anticipate all possible uses of your code.
Every answer above assumes range is of positive numbers only. Here is the solution to return list of consecutive numbers where arguments can be any (positive or negative), with the possibility to set optional step value (default = 1).
def any_number_range(a,b,s=1):
""" Generate consecutive values list between two numbers with optional step (default=1)."""
if (a == b):
return a
else:
mx = max(a,b)
mn = min(a,b)
result = []
# inclusive upper limit. If not needed, delete '+1' in the line below
while(mn < mx + 1):
# if step is positive we go from min to max
if s > 0:
result.append(mn)
mn += s
# if step is negative we go from max to min
if s < 0:
result.append(mx)
mx += s
return result
For instance, standard command list(range(1,-3))
returns empty list []
, while this function will return [-3,-2,-1,0,1]
Updated: now step may be negative. Thanks @Michael for his comment.
I would recommend to use Bootstrap. http://getbootstrap.com/. This approach is very straight-forward and light weight.
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-fixed-top">
<li><a href="#home"> <br>BLINK</a></li>
<li><a href="#news"><br>ADVERTISING WITH BLINK</a></li>
<li><a href="#contact"><br>EDUCATING WITH BLINK</a></li>
<li><a href="#about"><br>ABOUT US</a></li>
</ul>
</div>
</div>
</div>
You need to include the Bootstrap into your project, which will include the necessary scripts and styles. Then just call the class 'navbar-fixed-top'. This will do the trick. See above example
Certainly the credit goes to @Harvey Kwok here, but I just wanted to add this example because in my case I wanted to get an actual List of UserPrincipals. It's probably more efficient to filter this query upfront, but in my small environment, it's just easier to pull everything and then filter as needed later from my list.
Depending on what you need, you may not need to cast to DirectoryEntry, but some properties are not available from UserPrincipal.
using (var searcher = new PrincipalSearcher(new UserPrincipal(new PrincipalContext(ContextType.Domain, Environment.UserDomainName))))
{
List<UserPrincipal> users = searcher.FindAll().Select(u => (UserPrincipal)u).ToList();
foreach(var u in users)
{
DirectoryEntry d = (DirectoryEntry)u.GetUnderlyingObject();
Console.WriteLine(d.Properties["GivenName"]?.Value?.ToString() + d.Properties["sn"]?.Value?.ToString());
}
}
This method orderBy
does not change the input array,
you have to assign the result to your array :
var chars = this.state.characters;
chars = _.orderBy(chars, ['name'],['asc']); // Use Lodash to sort array by 'name'
this.setState({characters: chars})
I wrote myself a little wrapper, so I don't have to rewrite all of my code from the past decades, which emulates register_globals and the missing session functions.
I've picked up some ideas from different sources and put some own stuff to get a replacement for missing register_globals and missing session functions, so I don't have to rewrite all of my code from the past decades. The code also works with multidimensional arrays and builds globals from a session.
To get the code to work use auto_prepend_file
on php.ini to specify the file containing the code below. E.g.:
auto_prepend_file = /srv/www/php/.auto_prepend.php.inc
You should have runkit extension from PECL installed and the following entries on your php.ini:
extension_dir = <your extension dir>
extension = runkit.so
runkit.internal_override = On
.auto_prepend.php.inc:
<?php
//Fix for removed session functions
if (!function_exists('session_register'))
{
function session_register()
{
$register_vars = func_get_args();
foreach ($register_vars as $var_name)
{
$_SESSION[$var_name] = $GLOBALS[$var_name];
if (!ini_get('register_globals'))
{ $GLOBALS[$var_name] = &$_SESSION[$var_name]; }
}
}
function session_is_registered($var_name)
{ return isset($_SESSION[$var_name]); }
function session_unregister($var_name)
{ unset($_SESSION[$var_name]); }
}
//Fix for removed function register_globals
if (!isset($PXM_REG_GLOB))
{
$PXM_REG_GLOB=1;
if (!ini_get('register_globals'))
{
if (isset($_REQUEST)) { extract($_REQUEST); }
if (isset($_SERVER)) { extract($_SERVER); }
//$_SESSION globals must be registred with call of session_start()
// Best option - Catch session_start call - Runkit extension from PECL must be present
if (extension_loaded("runkit"))
{
if (!function_exists('session_start_default'))
{ runkit_function_rename("session_start", "session_start_default"); }
if (!function_exists('session_start'))
{
function session_start($options=null)
{
$return=session_start_default($options);
if (isset($_SESSION))
{
$var_names=array_keys($_SESSION);
foreach($var_names as $var_name)
{ $GLOBALS[$var_name]=&$_SESSION[$var_name]; }
}
return $return;
}
}
}
// Second best option - Will always extract $_SESSION if session cookie is present.
elseif ($_COOKIE["PHPSESSID"])
{
session_start();
if (isset($_SESSION))
{
$var_names=array_keys($_SESSION);
foreach($var_names as $var_name)
{ $GLOBALS[$var_name]=&$_SESSION[$var_name]; }

I am using this code, which I find more practical than the accepted answer above:
List<Thing> thingList = new ArrayList<>(thingSet);
thingList.sort((thing1, thing2) -> thing1.getName().compareToIgnoreCase(thing2.getName()));
@gimel's answer is correct if you can guarantee the package hierarchy he mentions. If you can't -- if your real need is as you expressed it, exclusively tied to directories and without any necessary relationship to packaging -- then you need to work on __file__
to find out the parent directory (a couple of os.path.dirname
calls will do;-), then (if that directory is not already on sys.path
) prepend temporarily insert said dir at the very start of sys.path
, __import__
, remove said dir again -- messy work indeed, but, "when you must, you must" (and Pyhon strives to never stop the programmer from doing what must be done -- just like the ISO C standard says in the "Spirit of C" section in its preface!-).
Here is an example that may work for you:
import sys
import os.path
sys.path.append(
os.path.abspath(os.path.join(os.path.dirname(__file__), os.path.pardir)))
import module_in_parent_dir
You need to specify how you'll authenticate with the database. If you want to use integrated security (this means using Windows authentication using your local or domain Windows account), add this to the connection string:
Integrated Security = True;
If you want to use SQL Server authentication (meaning you specify a login and password rather than using a Windows account), add this:
User ID = "username"; Password = "password";
The SublimeText 3 Column-Select plugin should be all you need. Install that, then make sure you have something like the following in your 'Default (OSX).sublime-keymap' file:
// Column mode
{ "keys": ["ctrl+alt+up"], "command": "column_select", "args": {"by": "lines", "forward": false}},
{ "keys": ["ctrl+alt+down"], "command": "column_select", "args": {"by": "lines", "forward": true}},
{ "keys": ["ctrl+alt+pageup"], "command": "column_select", "args": {"by": "pages", "forward": false}},
{ "keys": ["ctrl+alt+pagedown"], "command": "column_select", "args": {"by": "pages", "forward": true}},
{ "keys": ["ctrl+alt+home"], "command": "column_select", "args": {"by": "all", "forward": false}},
{ "keys": ["ctrl+alt+end"], "command": "column_select", "args": {"by": "all", "forward": true}}
What exactly about it did not work for you?
There's nothing deep happening here.. Basically, it's handy to test something to see if it's of a certain type (i.e. use 'as'). You would want to check the result of the 'as' call to see if the result is null.
When you expect a cast to work and you want the exception to be thrown, use the 'classic' method.
This is one way to do it:
SQL> set serveroutput on
SQL> CREATE OR REPLACE TYPE MyType AS VARRAY(200) OF VARCHAR2(50);
2 /
Type created
SQL> CREATE OR REPLACE PROCEDURE testing (t_in MyType) IS
2 BEGIN
3 FOR i IN 1..t_in.count LOOP
4 dbms_output.put_line(t_in(i));
5 END LOOP;
6 END;
7 /
Procedure created
SQL> DECLARE
2 v_t MyType;
3 BEGIN
4 v_t := MyType();
5 v_t.EXTEND(10);
6 v_t(1) := 'this is a test';
7 v_t(2) := 'A second test line';
8 testing(v_t);
9 END;
10 /
this is a test
A second test line
To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:
SQL> CREATE OR REPLACE PACKAGE p IS
2 TYPE p_type IS TABLE OF VARCHAR2(50) INDEX BY BINARY_INTEGER;
3
4 PROCEDURE pp (inp p_type);
5 END p;
6 /
Package created
SQL> CREATE OR REPLACE PACKAGE BODY p IS
2 PROCEDURE pp (inp p_type) IS
3 BEGIN
4 FOR i IN 1..inp.count LOOP
5 dbms_output.put_line(inp(i));
6 END LOOP;
7 END pp;
8 END p;
9 /
Package body created
SQL> DECLARE
2 v_t p.p_type;
3 BEGIN
4 v_t(1) := 'this is a test of p';
5 v_t(2) := 'A second test line for p';
6 p.pp(v_t);
7 END;
8 /
this is a test of p
A second test line for p
PL/SQL procedure successfully completed
SQL>
This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.
For the time being I am going a different route than I previous stated. I changed the way I am formatting the data to:
&A2168=1&A1837=5&A8472=1&A1987=2
On the server side I am using getParameterNames() to place all the keys into an Enumerator and then iterating over the Enumerator and placing the keys and values into a HashMap. It looks something like this:
Enumeration keys = request.getParameterNames();
HashMap map = new HashMap();
String key = null;
while(keys.hasMoreElements()){
key = keys.nextElement().toString();
map.put(key, request.getParameter(key));
}

With this 2 methods you can Open an Excel file, load it into a DataTable, do your modifications and save it back into an Excel file.
Hope you guys find this usefull.
Yes. You need to prefix the table name with "#" (hash) to create temporary tables.
If you do NOT need the table later, go ahead & create it. Temporary Tables are very much like normal tables. However, it gets created in tempdb. Also, it is only accessible via the current session i.e. For EG: if another user tries to access the temp table created by you, he'll not be able to do so.
"##" (double-hash creates "Global" temp table that can be accessed by other sessions as well.
Refer the below link for the Basics of Temporary Tables: http://www.codeproject.com/Articles/42553/Quick-Overview-Temporary-Tables-in-SQL-Server-2005
If the content of your table is less than 5000 rows & does NOT contain data types such as nvarchar(MAX), varbinary(MAX), consider using Table Variables.
They are the fastest as they are just like any other variables which are stored in the RAM. They are stored in tempdb as well, not in RAM.
DECLARE @ItemBack1 TABLE
(
column1 int,
column2 int,
someInt int,
someVarChar nvarchar(50)
);
INSERT INTO @ItemBack1
SELECT column1,
column2,
someInt,
someVarChar
FROM table2
WHERE table2.ID = 7;
More Info on Table Variables: http://odetocode.com/articles/365.aspx
I tried the above but I'm getting a database error complaining that the foreign key field in the Child table can not be NULL. Is there a way to tell JPA to automatically set this foreign key into the Child object so it can automatically save children objects?
Well, there are two things here.
First, you need to cascade the save operation (but my understanding is that you are doing this or you wouldn't get a FK constraint violation during inserts in the "child" table)
Second, you probably have a bidirectional association and I think that you're not setting "both sides of the link" correctly. You are supposed to do something like this:
Parent parent = new Parent();
...
Child c1 = new Child();
...
c1.setParent(parent);
List<Child> children = new ArrayList<Child>();
children.add(c1);
parent.setChildren(children);
session.save(parent);
A common pattern is to use link management methods:
@Entity
public class Parent {
@Id private Long id;
@OneToMany(mappedBy="parent")
private List<Child> children = new ArrayList<Child>();
...
protected void setChildren(List<Child> children) {
this.children = children;
}
public void addToChildren(Child child) {
child.setParent(this);
this.children.add(child);
}
}
And the code becomes:
Parent parent = new Parent();
...
Child c1 = new Child();
...
parent.addToChildren(c1);
session.save(parent);

Here's what I'm currently using. Some of the other techniques I've tried have been non-optimal because they changed the bit depth of the pixels (24-bit vs. 32-bit) or ignored the image's resolution (dpi).
// ImageConverter object used to convert byte arrays containing JPEG or PNG file images into
// Bitmap objects. This is static and only gets instantiated once.
private static readonly ImageConverter _imageConverter = new ImageConverter();

/// provides lossless compression. This can be used together with the GetImageFromByteArray()

public static byte[] CopyImageToByteArray(Image theImage)
{
using (MemoryStream memoryStream = new MemoryStream())
{
theImage.Save(memoryStream, ImageFormat.Png);
return memoryStream.ToArray();
}
}
Byte array to Image:
/// <summary>
/// Method that uses the ImageConverter object in .Net Framework to convert a byte array,

/// <returns>Bitmap object if it works, else exception is thrown</returns>
public static Bitmap GetImageFromByteArray(byte[] byteArray)
{
Bitmap bm = (Bitmap)_imageConverter.ConvertFrom(byteArray);
if (bm != null && (bm.HorizontalResolution != (int)bm.HorizontalResolution ||
bm.VerticalResolution != (int)bm.VerticalResolution))
{
// Correct a strange glitch that has been observed in the test program when converting
// from a PNG file image created by CopyImageToByteArray() - the dpi value "drifts"
// slightly away from the nominal integer value
bm.SetResolution((int)(bm.HorizontalResolution + 0.5f),
(int)(bm.VerticalResolution + 0.5f));
}
return bm;
}
Edit: To get the Image from a jpg or png file you should read the file into a byte array using File.ReadAllBytes():
Bitmap newBitmap = GetImageFromByteArray(File.ReadAllBytes(fileName));
This avoids problems related to Bitmap wanting its source stream to be kept open, and some suggested workarounds to that problem that result in the source file being kept locked.

Answering your question directly:
I'm trying to declare a
priority_queue
of nodes, usingbool Compare(Node a, Node b) as the comparator function
What I currently have is:
priority_queue<Node, vector<Node>, Compare> openSet;
For some reason, I'm getting Error:
"Compare" is not a type name
The compiler is telling you exactly what's wrong: Compare
is not a type name, but an instance of a function that takes two Nodes
and returns a bool
.
What you need is to specify the function pointer type:
std::priority_queue<Node, std::vector<Node>, bool (*)(Node, Node)> openSet(Compare)
If an URL pattern starts with /
, then it's relative to the context root. The /Admin/*
URL pattern would only match pages on http://localhost:8080/EMS2/Admin/*
(assuming that /EMS2
is the context path), but you have them actually on http://localhost:8080/EMS2/faces/Html/Admin/*
, so your URL pattern never matches.
You need to prefix your URL patterns with /faces/Html
as well like so:
<url-pattern>/faces/Html/Admin/*</url-pattern>
You can alternatively also just reconfigure your web project structure/configuration so that you can get rid of the /faces/Html
path in the URLs so that you can just open the page by for example http://localhost:8080/EMS2/Admin/Upload.xhtml
.
Your filter mapping syntax is all fine. However, a simpler way to specify multiple URL patterns is to just use only one <filter-mapping>
with multiple <url-pattern>
entries:
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/faces/Html/Employee/*</url-pattern>
<url-pattern>/faces/Html/Admin/*</url-pattern>
<url-pattern>/faces/Html/Supervisor/*</url-pattern>
</filter-mapping>
Select Operation : This operation is used to select rows from a table (relation) that specifies a given logic, which is called as a predicate
. The predicate is a user defined condition to select rows of user's choice.
Project Operation : If the user is interested in selecting the values of a few attributes, rather than selection all attributes of the Table (Relation), then one should go for PROJECT
Operation.

You need the correct argument for the nth-child
pseudo class.
The argument should be in the form of an + b
to match every ath child starting from b.
Both a
and b
are optional integers and both can be zero or negative.
a
is zero then there is no "every ath child" clause.a
is negative then matching is done backwards starting from b
.b
is zero or negative then it is possible to write equivalent expression using positive b
e.g. 4n+0
is same as 4n+4
. Likewise 4n-1
is same as 4n+3

This is how I enhance the enum inheritance pattern with runtime check in static initializer.
The BaseKind#checkEnumExtender
checks that "extending" enum declares all the values of the base enum in exactly the same way so #name()
and #ordinal()
remain fully compatible.
There is still copy-paste involved for declaring values but the program fails fast if somebody added or modified a value in the base class without updating extending ones.
Common behavior for different enums extending each other:
public interface Kind {
/**
* Let's say we want some additional member.
*/
String description() ;
/**
* Standard {@code Enum} method.
*/
String name() ;
/**
* Standard {@code Enum} method.
*/
int ordinal() ;
}
Base enum, with verifying method:
public enum BaseKind implements Kind {
FIRST( "First" ),
SECOND( "Second" ),
;
private final String description ;
public String description() {
return description ;
}
private BaseKind( final String description ) {
this.description = description ;
}
public static void checkEnumExtender(
final Kind[] baseValues,
final Kind[] extendingValues
) {
if( extendingValues.length < baseValues.length ) {
throw new IncorrectExtensionError( "Only " + extendingValues.length + " values against "
+ baseValues.length + " base values" ) ;
}
for( int i = 0 ; i < baseValues.length ; i ++ ) {
final Kind baseValue = baseValues[ i ] ;
final Kind extendingValue = extendingValues[ i ] ;
if( baseValue.ordinal() != extendingValue.ordinal() ) {
throw new IncorrectExtensionError( "Base ordinal " + baseValue.ordinal()
+ " doesn't match with " + extendingValue.ordinal() ) ;
}
if( ! baseValue.name().equals( extendingValue.name() ) ) {
throw new IncorrectExtensionError( "Base name[ " + i + "] " + baseValue.name()
+ " doesn't match with " + extendingValue.name() ) ;
}
if( ! baseValue.description().equals( extendingValue.description() ) ) {
throw new IncorrectExtensionError( "Description[ " + i + "] " + baseValue.description()
+ " doesn't match with " + extendingValue.description() ) ;
}
}
}
public static class IncorrectExtensionError extends Error {
public IncorrectExtensionError( final String s ) {
super( s ) ;
}
}
}
Extension sample:
public enum ExtendingKind implements Kind {
FIRST( BaseKind.FIRST ),
SECOND( BaseKind.SECOND ),
THIRD( "Third" ),
;
private final String description ;
public String description() {
return description ;
}
ExtendingKind( final BaseKind baseKind ) {
this.description = baseKind.description() ;
}
ExtendingKind( final String description ) {
this.description = description ;
}
}
You need Math.Round
, not Math.Ceiling
. Ceiling
always "rounds" up, while Round
rounds up or down depending on the value after the decimal point.
sys.argv
is the list of arguments passed to the Python program. The first argument, sys.argv[0]
, is actually the name of the program as it was invoked. That's not a Python thing, but how most operating systems work. The reason sys.argv[0]
exists is so you can change your program's behaviour depending on how it was invoked. sys.argv[1]
is thus the first argument you actually pass to the program.
Because lists (like most sequences) in Python start indexing at 0, and because indexing past the end of the list is an error, you need to check if the list has length 2 or longer before you can access sys.argv[1]
.
function ConvertDateFromDiv(divTimeStr) {
//eg:-divTimeStr=18/03/2013 12:53:00
var tmstr = divTimeStr.toString().split(' '); //'21-01-2013 PM 3:20:24'
var dt = tmstr[0].split('/');
var str = dt[2] + "/" + dt[1] + "/" + dt[0] + " " + tmstr[1]; //+ " " + tmstr[1]//'2013/01/20 3:20:24 pm'
var time = new Date(str);
if (time == "Invalid Date") {
time = new Date(divTimeStr);
}
return time;
}
Essentially random access file wraps input and output streams in order to manage the random access. You don't open and close a file, you open and close streams to a file.
It is called an array initializer and can be explained in the Java specification 10.6.
This can be used to initialize any array, but it can only be used for initialization (not assignment to an existing array). One of the unique things about it is that the dimensions of the array can be determined from the initializer. Other methods of creating an array require you to manually insert the number. In many cases, this helps minimize trivial errors which occur when a programmer modifies the initializer and fails to update the dimensions.
Basically, the initializer allocates a correctly sized array, then goes from left to right evaluating each element in the list. The specification also states that if the element type is an array (such as it is for your case... we have an array of double[]), that each element may, itself be an initializer list, which is why you see one outer set of braces, and each line has inner braces.

The ASHOT framework from Yandex can be used for taking screenshots in Selenium WebDriver scripts for
This framework can be found on https://github.com/yandex-qatools/ashot.
The code for taking the screenshots is very straightforward:
ENTIRE PAGE
screenshot = new AShot().shootingStrategy(
new ViewportPastingStrategy(1000)).takeScreenshot(driver);
ImageIO.write(screenshot.getImage(), "PNG", new File("c:\\temp\\results.png"));
SPECIFIC WEB ELEMENT
screenshot = new AShot().takeScreenshot(driver,
driver.findElement(By.xpath("(//div[@id='ct_search'])[1]")));
ImageIO.write(screenshot.getImage(), "PNG", new File("c:\\temp\\div_element.png"));

The join feature supported by Mongodb 3.2 and later versions. You can use joins by using aggregate query.
You can do it using below example :
db.users.aggregate([
// Join with user_info table
{
$lookup:{
from: "userinfo", // other table name
localField: "userId", // name of users table field
foreignField: "userId", // name of userinfo table field
as: "user_info" // alias for userinfo table
}
},
{ $unwind:"$user_info" }, // $unwind used for getting data in object or for one record only
// Join with user_role table
{
$lookup:{
from: "userrole",
localField: "userId",
foreignField: "userId",
as: "user_role"
}
},
{ $unwind:"$user_role" },
// define some conditions here
{
$match:{
$and:[{"userName" : "admin"}]
}
},
// define which fields are you want to fetch
{
$project:{
_id : 1,
email : 1,
userName : 1,
userPhone : "$user_info.phone",
role : "$user_role.role",
}
}
]);
This will give result like this:
{
"_id" : ObjectId("5684f3c454b1fd6926c324fd"),
"email" : "[email protected]",
"userName" : "admin",
"userPhone" : "0000000000",
"role" : "admin"
}
Hope this will help you or someone else.
Thanks
According to me the best way of dealing with such problems and avoiding couple of condition required for checking the the height of device, is using the relative frame for views or any UI element which you are adding to you view for example: if you are adding some UI element which you want should at the bottom of view or just above tab bar then you should take the y origin with respect to your view's height or with respect to tab bar (if present) and we have auto resizing property as well. I hope this will work for you
First thing you should do is go into the logs (Management\SQL Server Logs
) and see if SQL Server successfully registered the Service Principal Name (SPN)
. If you see some sort of error (The SQL Server Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service
) then you know where to start.
We saw this happen when we changed the account SQL Server was running under. Resetting it to Local System Account solved the problem. Microsoft also has a guide on manually configuring the SPN.
If you have tried all the other answers, and it still hasn't work, you can try skipping a line:
Scanner scan = new Scanner(System.in);
scan.nextLine();
String s = scan.nextLine();
System.out.println("String is " + s);
I found the best way to send input is to use cat and a text file to pass along whatever input you need.
cat "input.txt" | ./Script.sh
You should set it with C:\Program Files\Java\jdk1.8.0_12
.
\bin
is not required.
echo "Enter no of terms"
read count
for i in $(seq 1 $count)
do
t=` expr $i - 1 `
for j in $(seq $t -1 0)

j=` expr $count + 1 `
x=` expr $j - $i `
for k in $(seq 1 $x)

MS already made a method for this, so you dont have to use the null coalescing operator. No difference in functionality, but it is easier for non-experts to get what is happening at a glance.

Does it have to be an actual enum? How about using a Dictionary<string,int>
instead?
for example
Dictionary<string, int> MyEnum = new Dictionary(){{"One", 1}, {"Two", 2}};
Console.WriteLine(MyEnum["One"]);
Just to complement the answer that I thought best, I also use less -SFX
but in a different way: I like to ad it to my .my.cnf
file in my home folder, an example cnf file looks like this:
[client]
user=root
password=MyPwD
[mysql]
pager='less -SFX'
The good thing about having it this way, is that less
is only used when the output of a query is actually more than one page long, here is the explanation of all the flags:
Note: in the .my.cnf
file don't put the pager
command below the [client]
keyword; although it might work with mysql
well, mysqldump
will complain about not recognizing it.
I assume you want to link to a library called foo, its filename is usually something link foo.dll
or libfoo.so
.
1. Find the library
You have to find the library. This is a good idea, even if you know the path to your library. CMake will error out if the library vanished or got a new name. This helps to spot error early and to make it clear to the user (may yourself) what causes a problem.
To find a library foo and store the path in FOO_LIB
use
find_library(FOO_LIB foo)
CMake will figure out itself how the actual file name is. It checks the usual places like /usr/lib
, /usr/lib64
and the paths in PATH
.
You already know the location of your library. Add it to the CMAKE_PREFIX_PATH
when you call CMake, then CMake will look for your library in the passed paths, too.
Sometimes you need to add hints or path suffixes, see the documentation for details: https://cmake.org/cmake/help/latest/command/find_library.html
2. Link the library
From 1. you have the full library name in FOO_LIB
. You use this to link the library to your target GLBall
as in
target_link_libraries(GLBall PRIVATE "${FOO_LIB}")
You should add PRIVATE
, PUBLIC
, or INTERFACE
after the target, cf. the documentation:
https://cmake.org/cmake/help/latest/command/target_link_libraries.html
If you don't add one of these visibility specifiers, it will either behave like PRIVATE
or PUBLIC
, depending on the CMake version and the policies set.
3. Add includes (This step might be not mandatory.)
If you also want to include header files, use find_path
similar to find_library
and search for a header file. Then add the include directory with target_include_directories
similar to target_link_libraries
.
Documentation: https://cmake.org/cmake/help/latest/command/find_path.html and https://cmake.org/cmake/help/latest/command/target_include_directories.html
If available for the external software, you can replace find_library
and find_path
by find_package
.
If you are using Typescript 3.7 or newer you can now also do:
const data = change?.after?.data();
if(!data) {
console.error('No data here!');
return null
}
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
Typescript is saying that change
or data
is possibly undefined
(depending on what onUpdate
returns).
So you should wrap it in a null/undefined check:
if(change && change.after && change.after.data){
const data = change.after.data();
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
}
If you are 100% sure that your object
is always defined then you can put this:
const data = change.after!.data();
Bash:
find -type f -printf "%T@ %p \n" \
| sort \
| tail -n 1 \
| sed -r "s/^\S+\s//;s/\s*$//" \
| xargs -iSTR cp STR newestfile
where "newestfile" will become the newestfile
alternatively, you could do newdir/STR or just newdir
Breakdown:
Important
After running this once, the newest file will be whatever you just copied :p ( assuming they're both in the same search scope that is ). So you may have to adjust which filenumber you copy if you want this to work more than once.
There are many realizations of hash functions written in JS. For example:
If you don't need security, you can also use base64 which is not hash-function, has not fixed output and could be simply decoded by user, but looks more lightweight and could be used for hide values: http://www.webtoolkit.info/javascript-base64.html
I believe you are looking for -maxdepth 1

I had the same issue. Fixed by adding a pom.xml in parent folder with <modules>
listed.
Rather than using booleans, why not just set the button to false when its clicked, so you do that in your actionPerformed method. Its more efficient..
if (command.equals("w"))
{
FileConverter fc = new FileConverter();
btnConvertDocuments.setEnabled(false);
}
This is for vmware workstation 6.5
It is pretty far down.
select Create new virtual machine ->
select custom ->
on compatibility page take defaults ->
check I will install os later
-> click through several pages choosing other for OS, give it a name, make sure it IS NOT in the same folder as the VMDK file. Choose bridged network.
You will now see a screen asking to select disk, select existing virual disk. then browse and select the VMDK file
By default p
tags are block
elements, which means they take 100% of the parent width
.
You can change their display property with:
#container p {
display:inline-block;
}
But it puts the elements side by side.
To keep each element on its own line you can use:
#container p {
clear:both;
float:left;
}
(If you use float and need to clear after floated elements, see this link for different techniques: http://css-tricks.com/all-about-floats/)
Demo: http://jsfiddle.net/CvJ3W/5/
Edit
If you go for the solution with display:inline-block
but want to keep each item in one line, you can just add a <br>
tag after each one:
<div id="container">
<p>Sample Text 1</p><br/>
<p>Sample Text 2</p><br/>
<p>Sample Text 3</p><br/>
</div>

A basic for statement includes
ForInit
)boolean
or Boolean
(ForStatement
) andForUpdate
)If you need multiple conditions to build your ForStatement, then use the standard logic operators (&&
, ||
, |
, ...) but - I suggest to use a private method if it gets to complicated:
for (int i = 0, j = 0; isMatrixElement(i,j,myArray); i++, j++) {
// ...
}
and
private boolean isMatrixElement(i,j,myArray) {
return (i < myArray.length) && (j < myArray[i].length); // stupid dummy code!

New release androidx.activity ver. 1.0.0-alpha07 brings some changes
More explanations in android official guide: Provide custom back navigation
Example:
public class MyFragment extends Fragment {
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// This callback will only be called when MyFragment is at least Started.
OnBackPressedCallback callback = new OnBackPressedCallback(true /* enabled by default */) {
@Override
public void handleOnBackPressed() {
// Handle the back button event
}
};
requireActivity().getOnBackPressedDispatcher().addCallback(this, callback);
// The callback can be enabled or disabled here or in handleOnBackPressed()
}
...
}
UPD: April 3rd, 2019
Now its simplified. More info here
Example:
requireActivity().getOnBackPressedDispatcher().addCallback(getViewLifecycleOwner(), this);
@Override
public boolean handleOnBackPressed() {
//Do your job here
//use next line if you just need navigate up
//NavHostFragment.findNavController(this).navigateUp();
//Log.e(getClass().getSimpleName(), "handleOnBackPressed");
return true;
}
Deprecated (since Version 1.0.0-alpha06 April 3rd, 2019) :
Since this, it can be implemented just using JetPack implementation OnBackPressedCallback
in your fragment
and add it to activity:
getActivity().addOnBackPressedCallback(getViewLifecycleOwner(),this);
Your fragment should looks like this:
public MyFragment extends Fragment implements OnBackPressedCallback {
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getActivity().addOnBackPressedCallback(getViewLifecycleOwner(),this);
}
@Override
public boolean handleOnBackPressed() {
//Do your job here
//use next line if you just need navigate up
//NavHostFragment.findNavController(this).navigateUp();
//Log.e(getClass().getSimpleName(), "handleOnBackPressed");
return true;
}
@Override
public void onDestroyView() {
super.onDestroyView();
getActivity().removeOnBackPressedCallback(this);
}
}
UPD:
Your activity should extends AppCompatActivity
or FragmentActivity
and in Gradle file:
implementation 'androidx.appcompat:appcompat:{lastVersion}'
In the real world, scenario its not about calling a simple function but a function with a proper value. So let's dive in. This is the scenario A user has a requirement to fire an event from his own component and also at the end he wants to call a function of another component as well. Let's say the service file is the same for both the components
componentOne.html
<button (click)="savePreviousWorkDetail()" data-dismiss="modal" class="btn submit-but" type="button">
Submit
</button>
When the user clicks on the submit button he needs to call savePreviousWorkDetail() in its own component componentOne.ts and in the end he needs to call a function of another component as well. So to do that a function in a service class can be called from componentOne.ts and when that called, the function from componentTwo will be fired.
componentOne.ts
constructor(private httpservice: CommonServiceClass) {
}
savePreviousWorkDetail() {
// Things to be Executed in this function
this.httpservice.callMyMethod("Niroshan");
}
commontServiceClass.ts
import {Injectable,EventEmitter} from '@angular/core';
@Injectable()
export class CommonServiceClass{
invokeMyMethod = new EventEmitter();
constructor(private http: HttpClient) {
}
callMyMethod(params: any = 'Niroshan') {
this.invokeMyMethod.emit(params);
}
}
And Below is the componentTwo which has the function that needed to be called from componentOne. And in ngOnInit() we have to subscribe for the invoked method so when it triggers methodToBeCalled() will be called
componentTwo.ts
import {Observable,Subscription} from 'rxjs';
export class ComponentTwo implements OnInit {
constructor(private httpservice: CommonServiceClass) {
}
myMethodSubs: Subscription;
ngOnInit() {
this.myMethodSubs = this.httpservice.invokeMyMethod.subscribe(res => {
console.log(res);
this.methodToBeCalled();
});
methodToBeCalled(){
//what needs to done
}
}
}
In your view template, set a default value:
f.text_field :password, :value => "password"
In your Javascript (assuming jquery here):
$(document).ready(function() {
//add a handler to remove the text
});
In your case, since you are only showing 3 columns:
Name Value Business
or
Name Business Ecommerce Pro
why not set all 3 to have a width of 33.3%. since only 3 are ever shown at once, the browser should render them all a similar width.
If to use disabled
form input elements (like suggested in correct answer
how to disable input) validation for them will be also disabled, take attention for that!
(And if you are using on submit button like [disabled]="!form.valid"
it will exclude your field from validation)
You can simply add this to Gradle dependencies:
compile "org.apache.httpcomponents:httpcore:4.3.2"
To create all intermediate-level destination directories you could use os.makedirs()
before copying:
import os
import shutil
srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'
assert not os.path.isabs(srcfile)
dstdir = os.path.join(dstroot, os.path.dirname(srcfile))
os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)
If you are using this line:
sessionFactory.getHibernateProperties().put("hibernate.dialect", env.getProperty("hibernate.dialect"));
make sure that env.getProperty("hibernate.dialect")
is not null.
You can use the bootstrap grid system. as Yoann said
<div class="container">
<div class="row">
<form role="form">
<div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
</div>
<div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
<label for="exampleInputEmail1">Name</label>
<input type="text" class="form-control" id="exampleInputEmail1" placeholder="Enter Name">
</div>
<div class="clearfix"></div>
<div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
<label for="exampleInputPassword1">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
</div>
<div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
<label for="exampleInputPassword1">Confirm Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Confirm Password">

What is Valid Architectures (VALID_ARCHS) into Xcode build-settings?
Example :- One iOS project has following build-settings into Xcode.
At the beginning of your file you set raw_input
to 0. Do not do this, at it modifies the built-in raw_input()
function. Therefore, whenever you call raw_input()
, it is essentially calling 0()

The difference is that GET sends data open and POST hidden (in the http-header).
So get is better for non-secure data, like query strings in Google. Auth-data shall never be send via GET - so use POST here. Of course the whole theme is a little more complicated. If you want to read more, read this article (in German).
Make it simple and use R basic functions:
# To get the LEFT part:
> substr(a, 1, 4)
[1] "left"
>
# To get the MIDDLE part:
> substr(a, 3, 7)
[1] "ftrig"
>
# To get the RIGHT part:
> substr(a, 5, 10)
[1] "right"
The substr()
function tells you where start and stop substr(x, start, stop)
As already stated, screen -S SESSIONTITLE
works for starting a session with a title (SESSIONTITLE
), but if you start a session and later decide to change its title. This can be accomplished by using the default key bindings:
Ctrl+a, A
Which prompts:
Set windows title to:SESSIONTITLE
Change SESSIONTITLE
by backspacing and typing in the desired title. To confirm the name change and list all titles.
Ctrl+a, "
I found a "neat" reflection tweak on "the interwebs" that I like to share. (origin: https://towardsdatascience.com/create-an-ordered-jsonobject-in-java-fb9629247d76)
It is about to change underlying collection in org.json.JSONObject to an un-ordering one (LinkedHashMap) by reflection API.
I tested succesfully:
import java.lang.reflect.Field;
import java.util.LinkedHashMap;
import org.json.JSONObject;
private static void makeJSONObjLinear(JSONObject jsonObject) {
try {
Field changeMap = jsonObject.getClass().getDeclaredField("map");
changeMap.setAccessible(true);
changeMap.set(jsonObject, new LinkedHashMap<>());
changeMap.setAccessible(false);
} catch (IllegalAccessException | NoSuchFieldException e) {
e.printStackTrace();
}
}
[...]
JSONObject requestBody = new JSONObject();
makeJSONObjLinear(requestBody);
requestBody.put("username", login);
requestBody.put("password", password);
[...]
// returned '{"username": "billy_778", "password": "********"}' == unordered
// instead of '{"password": "********", "username": "billy_778"}' == ordered (by key)
Either way is okay in python. I would personally prefer "". but again, either way is okay

Assuming your regexp engine supports negative lookaheads..
Edit: ..or maybe you'd prefer to use [A-Za-z]{6}
in place of .{6}
Edit (again): Note that lookaheads and lookbehinds are generally not the right way to "inverse" a regular expression match. Regexps aren't really set up for doing negative matching, they leave that to whatever language you are using them with.
To answer your titular question, you use [0]
to access the first element, but as it stands mandrill_events
contains a string not an array, so mandrill_events[0]
will just get you the first character, '['.
So either correct your source to:
var req = { mandrill_events: [{"event":"inbound","ts":1426249238}] };
and then req.mandrill_events[0]
, or if you're stuck with it being a string, parse the JSON the string contains:
var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' };
var mandrill_events = JSON.parse(req.mandrill_events);
var result = mandrill_events[0];
I typically use function attributes as storage for annotations. Suppose I want to write, in the style of C# (indicating that a certain method should be part of the web service interface)
class Foo(WebService):
@webmethod
def bar(self, arg1, arg2):
...
then I can define
def webmethod(func):
func.is_webmethod = True
return func
Then, when a webservice call arrives, I look up the method, check whether the underlying function has the is_webmethod attribute (the actual value is irrelevant), and refuse the service if the method is absent or not meant to be called over the web.
dynamic MyDynamic = new System.Dynamic.ExpandoObject();
MyDynamic.A = "A";
MyDynamic.B = "B";
MyDynamic.C = "C";

MyDynamic.MyMethod = new Func<int>(() =>
{
return 55;
});
Console.WriteLine(MyDynamic.MyMethod());

If your targetSdkVersion >= 24
, then we have to use FileProvider
class to give access to the particular file or folder to make them accessible for other apps. We create our own class inheriting FileProvider
in order to make sure our FileProvider doesn't conflict with FileProviders declared in imported dependencies as described here.
Steps to replace file://
URI with content://
URI:
<provider>
tag in AndroidManifest.xml
under <application>
tag. Specify a unique authority for the android:authorities
attribute to avoid conflicts, imported dependencies might specify ${applicationId}.provider
and other commonly used authorities.<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...
<application
...
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
</application>
</manifest>
provider_paths.xml
file in res/xml
folder. A folder may be needed to be created if it doesn't exist yet. The content of the file is shown below. It describes that we would like to share access to the External Storage at root folder (path=".")
with the name external_files.<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="."/>
</paths>
The final step is to change the line of code below in
Uri photoURI = Uri.fromFile(createImageFile());
to
Uri photoURI = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", createImageFile());
Edit: If you're using an intent to make the system open your file, you may need to add the following line of code:
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Please refer to the full code and solution that have been explained here.

std::copy does the job as far as moving elements is concerned:
#include <algorithm>
std::copy(array+3, array+5, array+2);
Note that the precondition for copy is that the destination must not be in the source range. It's permissible for the ranges to overlap.
Also, because of the way arrays work in C++, this doesn't "shorten" the array. It just shifts elements around within it. There is no way to change the size of an array, but if you're using a separate integer to track its "size" meaning the size of the part you care about, then you can of course decrement that.
So, the array you'll end up with will be as if it were initialized with:
int array[] = {1,2,4,5,5};
We can not quit app using exit(0)
, abort()
functions, as Apple strongly discourage the use of these functions. Though you can use this functions for development or testing purpose.
If during development or testing it is necessary to terminate your application, the abort function, or assert macro is recommended
Please find this Apple Q&A thread to get more information.
As use of this function create impression like application is crashing. So i got some suggestion like we can display Alert with termination message to aware user about closing the app, due to unavailability of certain functionality.
But iOS Human Interface Guideline for Starting And Stopping App, suggesting that Never use Quit or Close button to terminate Application. Rather then that they are suggesting to display proper message to explain situation.
An iOS app never displays a Close or Quit option. People stop using an app when they switch to another app, return to the Home screen, or put their devices in sleep mode.
Never quit an iOS app programmatically. People tend to interpret this as a crash. If something prevents your app from functioning as intended, you need to tell users about the situation and explain what they can do about it.

Use a native SQL query by specifying a @NamedNativeQuery
annotation on the entity class, or by using the EntityManager.createNativeQuery
method. You will need to specify the type of the ResultSet using an appropriate class, or use a ResultSet mapping.
Raw sql query is fastest way I suppose
public void DeleteCustomer(int id)
{
using (var context = new Context())
{
const string query = "DELETE FROM [dbo].[Customers] WHERE [id]={0}";
var rows = context.Database.ExecuteSqlCommand(query,id);
// rows >= 1 - count of deleted rows,
// rows = 0 - nothing to delete.
}
}

Hope this helps, with Serverless framework you can do something like this:
plugins:
- serverless-webpack
custom:
webpackIncludeModules:
forceInclude:
- <your package name> (for example: node-fetch)
2. Then create your Lambda function, deploy it by serverless deploy
, the package that included in serverless.yml will be there for you.
For more information about serverless: https://serverless.com/framework/docs/providers/aws/guide/quick-start/
yourbox{
position:absolute;
right:<x>px;
top :<x>px;
}
positions it in the right corner. Note, that the position is dependent of the first ancestor-element which is not static
positioned!
EDIT:
This error is caused by binary data being inserted into a buffer. To solve this problem, you should insert one statement in your code.
This statement is:
obj_FileStream.Read(Img, 0, Convert.ToInt32(obj_FileStream.Length));
Example:
FileStream obj_FileStream = new FileStream(str_ImagePath, FileMode.OpenOrCreate, FileAccess.Read);
Byte[] Img = new Byte[obj_FileStream.Length];
obj_FileStream.Read(Img, 0, Convert.ToInt32(obj_FileStream.Length));
dt_NewsFeedByRow.Rows[0][6] = Img;
If you're in netbeans you can right click in the test method and click "Run Focused Test Method".
Just as a suggestion:
<?php echo date("W", strtotime("2012-10-18")); ?>
Might be a little simpler than all that lot.
Other things you could do:
<?php echo date("Weeknumber: W", strtotime("2012-10-18 01:00:00")); ?>
<?php echo date("Weeknumber: W", strtotime($MY_DATE)); ?>
switch ((i != null) ? i : DEFAULT_VALUE) {
//...
}
Update: This answer is more relevant for Rails 4.x
Do this:
current_user.comments.where(:id=>[123,"456","Michael Jackson"])
The stronger side of this approach is that it returns a Relation
object, to which you can join more .where
clauses, .limit
clauses, etc., which is very helpful. It also allows non-existent IDs without throwing exceptions.
The newer Ruby syntax would be:
current_user.comments.where(id: [123, "456", "Michael Jackson"])
I had the same issue. Fixed it by adding a static route on my host to my VM via the VMnet8 adapter:
route ADD VM_addr MASK 255.255.255.255 VMnet8_addr
As previously mentioned, you need a bridged connection.
SELECT id FROM a -- returns 1,4,2,3
UNION
SELECT id FROM b -- returns 2,1
order by 2,1
The technical definition of an operating system is "a platform that consists of specific set of libraries and infrastructure for applications to be built upon and interact with each other". A kernel is an operating system in that sense.
The end-user definition is usually something around "a software package that provides a desktop, shortcuts to applications, a web browser and a media player". A kernel doesn't match that definition.
So for an end-user a Linux distribution (say Ubuntu) is an Operating System while for a programmer the Linux kernel itself is a perfectly valid OS depending on what you're trying to achieve. For instance embedded systems are mostly just kernel with very small number of specialized processes running on top of them. In that case the kernel itself becomes the OS itself.
I think you can draw the line at what the majority of the applications running on top of that OS do require. If most of them require only kernel, the kernel is the OS, if most of them require X Window System running, then your OS becomes X + kernel.
The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods
index.php
<html>
<body>
<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>
</body>
</html>
site2.php
<html>
<body>
Hello <?php echo $_POST["name"]; ?>!<br>
Your mail is <?php echo $_POST["mail"]; ?>.
</body>
</html>
output
Hello "name" !
Your email is "[email protected]" .
Just to add for Rodrigo post, instead of LAST_INSERT_ID() in query you can use SELECT MAX(id) FROM table1;, but you must use (),
INSERT INTO table1 (title,userid) VALUES ('test', 1)
INSERT INTO table2 (parentid,otherid,userid) VALUES ( (SELECT MAX(id) FROM table1), 4, 1)
I guess something like this would be cleaner, and provide you with more flexibility with the output format (simply change template):
String template = "%s=\"%s\",";
StringBuilder sb = new StringBuilder();
for (Entry e : map.entrySet()) {
sb.append(String.format(template, e.getKey(), e.getValue()));
}
if (sb.length() > 0) {
sb.deleteCharAt(sb.length() - 1); // Ugly way to remove the last comma
}
return sb.toString();
I know having to remove the last comma is ugly, but I think it's cleaner than alternatives like the one in this solution or manually using an iterator.
char[] characters;
...
string s = new string(characters);
I encounter this problem because I did kill task to "Oracle" task in the Task Manager.
To fix it you need to open the cmd -> type: services.msc
-> the window with all services will open -> find service "OracleServiceXE
" -> right click: start.
Try the below code snippet:
with open(path, 'rb') as f:
text = f.read()
You must create a migration, where you will specify default value for a new field, since you don't want it to be null. If null is not required, simply add null=True
and create and run migration.
I suggest you to use fnmatch and the upper method. In this way you can find any of the following:
.
import fnmatch
import os
for file in os.listdir("/Users/Johnny/Desktop/MyTXTfolder"):
if fnmatch.fnmatch(file.upper(), '*.TXT'):
print(file)
You can get a graphical view of the project history with tools like gitk
. Just run:
gitk --all
If you want to checkout a specific branch:
git checkout <branch name>
For a specific commit, use the SHA1 hash instead of the branch name. (See Treeishes in the Git Community Book, which is a good read, to see other options for navigating your tree.)
git log
has a whole set of options to display detailed or summary history too.
I don't know of an easy way to move forward in a commit history. Projects with a linear history are probably not all that common. The idea of a "revision" like you'd have with SVN or CVS doesn't map all that well in Git.
Amit's answer tells you how to get your AWS_ACCESS_KEY_ID
, but the Your Security Credentials page won't reveal your AWS_SECRET_ACCESS_KEY
. As this blog points out:
Secret access keys are, as the name implies, secrets, like your password. Just as AWS doesn’t reveal your password back to you if you forgot it (you’d have to set a new password), the new security credentials page does not allowing retrieval of a secret access key after its initial creation. You should securely store your secret access keys as a security best practice, but you can always generate new access keys at any time.
So if you don't remember your AWS_SECRET_ACCESS_KEY
, the blog goes on to tell how to create a new one:
As for your other questions:
MERCHANT_ID
and MARKETPLACE_ID
.Even though --files
is no longer supported, you can use an env variable to provide a list of files:
// karma.conf.js
function getSpecs(specList) {
if (specList) {
return specList.split(',')
} else {
return ['**/*_spec.js'] // whatever your default glob is
}
}
module.exports = function(config) {
config.set({
//...
files: ['app.js'].concat(getSpecs(process.env.KARMA_SPECS))
});
});
Then in CLI:
$ env KARMA_SPECS="spec1.js,spec2.js" karma start karma.conf.js --single-run
You can also use numpy.invert
:
In [1]: import numpy as np
In [2]: import pandas as pd
In [3]: s = pd.Series([True, True, False, True])
In [4]: np.invert(s)
Out[4]:
0 False
1 False
2 True
3 False
EDIT: The difference in performance appears on Ubuntu 12.04, Python 2.7, NumPy 1.7.0 - doesn't seem to exist using NumPy 1.6.2 though:
In [5]: %timeit (-s)
10000 loops, best of 3: 26.8 us per loop
In [6]: %timeit np.invert(s)
100000 loops, best of 3: 7.85 us per loop
In [7]: %timeit ~s
10000 loops, best of 3: 27.3 us per loop

Finally resolved my java install issue on Win 7 64-bit running IE11.
Even though I installed the latest Java (65) via a java auto-update prompt, tried a verify java version and java failed to run, shut down all IE instances, failed to run verify again, shut down all running programs, failed to run verify again, rebooted, failed to run verify again, re-installed 65 again (shutting down the browser manually as it downloaded), and finally verify ran. What a pain.
The message I kept receiving was "The page you are viewing uses Java ..."; e.g. https://www.java.com/en/download/help/ie_tips.xml. I do use sleep mode on my desktop and I believe that this is probably the major issue with install and IE with its "clever" integration into the OS and explorer/desktop. I thought the government told them to not do that. I've had issues with CD-ROM drive disappearing and other unexplained periodic issues; all cured after a full reboot. They are infrequent, so I live with them for the convenience of faster startup times.
Hope this helps someone!
Simply best way from linux server
sudo mysql --defaults-file=/etc/mysql/debian.cnf -e 'use mysql;UPDATE user SET password=PASSWORD("snippetbucket-technologies") WHERE user="root";FLUSH PRIVILEGES;'
This way work for any linux server, I had 100% sure on Debian and Ubuntu you win.
If there is a reason you can't use the simple solution provided by ennuikiller above, then you will have to use Typeglobs to manipulate file handles. This is way more work. This example copies from the file in $ARGV[0]
to that in $ARGV[1]
. It defaults to STDIN
and STDOUT
respectively if files are not specified.
use English;
my $in;
my $out;
if ($#ARGV >= 0){
unless (open($in, "<", $ARGV[0])){
die "could not open $ARGV[0] for reading.";
}
}
else {
$in = *STDIN;
}
if ($#ARGV >= 1){
unless (open($out, ">", $ARGV[1])){
die "could not open $ARGV[1] for writing.";
}
}
else {
$out = *STDOUT;
}
while ($_ = <$in>){
$out->print($_);
}
One practical difference is that if you write a shell script for Mac OS X and save it as plain UTF-8, you will get the response:
#!/bin/bash: No such file or directory
in response to the shebang line specifying which shell you wish to use:
#!/bin/bash
If you save as UTF-8, no BOM (say in BBEdit) all will be well.
The next link will bring you to a great tutorial, that helped me a lot!
I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}
For GVIM, hit v
to go into visual mode; select text and hit Ctrl+Insert
to copy selection into global clipboard.
From the menu you can see that the shortcut key is "+y
i.e. hold Shift key, then press "
, then +
and then release Shift and press y
(cumbersome in comparison to Shift+Insert).

You can embed websites into another website using the <embed>
tag, like so:
<embed src="http://www.example.com" style="width:500px; height: 300px;">
You can change the height, width, and URL to suit your needs.
The <embed>
tag is the most up-to-date way to embed websites, as it was introduced with HTML5.
EDIT: using c++14, the best solution is very easy to write thanks to lambdas that can now have parameters of type auto
. This is my current favorite solution
std::sort(v.begin(), v.end(), [](auto &left, auto &right) {
return left.second < right.second;
});
Just use a custom comparator (it's an optional 3rd argument to std::sort
)
struct sort_pred {
bool operator()(const std::pair<int,int> &left, const std::pair<int,int> &right) {
return left.second < right.second;
}
};
std::sort(v.begin(), v.end(), sort_pred());
If you're using a C++11 compiler, you can write the same using lambdas:
std::sort(v.begin(), v.end(), [](const std::pair<int,int> &left, const std::pair<int,int> &right) {
return left.second < right.second;
});
EDIT: in response to your edits to your question, here's some thoughts ... if you really wanna be creative and be able to reuse this concept a lot, just make a template:
template <class T1, class T2, class Pred = std::less<T2> >
struct sort_pair_second {
bool operator()(const std::pair<T1,T2>&left, const std::pair<T1,T2>&right) {
Pred p;
return p(left.second, right.second);
}
};
then you can do this too:
std::sort(v.begin(), v.end(), sort_pair_second<int, int>());
or even
std::sort(v.begin(), v.end(), sort_pair_second<int, int, std::greater<int> >());
Though to be honest, this is all a bit overkill, just write the 3 line function and be done with it :-P
I have same problem with the most basic situation and my problem was solved with inserting this meta in the head:
<meta charset="UTF-8">
the character encoding (which is actually UTF-8) of the html document was not declared
Turns out that Evan Larsen has the best answer. Please upvote his answer (and/or select it as the correct answer) - it's brilliant.
Using Evan's trick, you can instantiate all tooltips with one line of code:
$('[data-toggle="tooltip"]').tooltip({'placement': 'top'});
You will see that all tooltips in your long paragraph have working tooltips with just that one line.
In the jsFiddle example (link above), I also added a situation where one tooltip (by the Sign-In button) is ON by default. Also, the tooltip code is ADDED to the button in jQuery, not in the HTML markup.
Popovers do work the same as the tooltips:
$('[data-toggle="popover"]').popover({trigger: 'hover','placement': 'top'});
And there you have it! Success at last.
One of the biggest problems in figuring this stuff out was making bootstrap work with jsFiddle... Here's what you must do:
NOW you are ready to go.
// Remove n last characters
// System.out.println(removeLast("Hello!!!333",3));
public String removeLast(String mes, int n) {
return mes != null && !mes.isEmpty() && mes.length()>n
? mes.substring(0, mes.length()-n): mes;
}
// Leave substring before character/string
// System.out.println(leaveBeforeChar("Hello!!!123", "1"));
public String leaveBeforeChar(String mes, String last) {
return mes != null && !mes.isEmpty() && mes.lastIndexOf(last)!=-1
? mes.substring(0, mes.lastIndexOf(last)): mes;
}
I believe I have found a better solution. The idea to change the function to python universal function (see documentation), which can exercise parallel computation under the hood.
One can write his own customised ufunc
in C, which surely is more efficient, or by invoking np.frompyfunc
, which is built-in factory method. After testing, this is more efficient than np.vectorize
:
f = lambda x, y: x * y
f_arr = np.frompyfunc(f, 2, 1)
vf = np.vectorize(f)
arr = np.linspace(0, 1, 10000)
%timeit f_arr(arr, arr) # 307ms
%timeit f_arr(arr, arr) # 450ms
I have also tested larger samples, and the improvement is proportional. For comparison of performances of other methods, see this post
