Just go to Web.Config
from Main
folder, not the one in Views
Folder:
configSections
section name="entityFramework" type="System.Data. .....,Version=" <strong>5</strong>.0.0.0"..
<..>
ADJUST THE VERSION OF EntityFramework you have installed, ex. like Version 6.0.0.0"
First you need to publish the file by:
BUILD -> PUBLISH or by right clicking project on Solution Explorer -> properties -> publish or select project in Solution Explorer and press Alt + Enter NOTE: if you are using Visual Studio 2013 then in properties you have to go to BUILD and then you have to disable define DEBUG constant and define TRACE constant and you are ready to go.
Save your file to a particular folder.
Find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug
folder below the project file (.csproj).
In Visual Studio they are in the Application Files folder and inside that you just need the .exe and dll files.
(You have to delete ClickOnce and other files and then make this folder a zip file and distribute it.)
NOTE: The ClickOnce application does install the project to system, but it has one advantage. You DO NOT require administrative privileges here to run (if your application follows the normal guidelines for which folders to use for application data, etc.).
The ASP.NET Web API has replaced the WCF Web API previously mentioned.
I thought I'd post an updated answer since most of these responses are from early 2012, and this thread is one of the top results when doing a Google search for "call restful service C#".
Current guidance from Microsoft is to use the Microsoft ASP.NET Web API Client Libraries to consume a RESTful service. This is available as a NuGet package, Microsoft.AspNet.WebApi.Client. You will need to add this NuGet package to your solution.
Here's how your example would look when implemented using the ASP.NET Web API Client Library:
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Net.Http.Headers;
namespace ConsoleProgram
{
public class DataObject
{
public string Name { get; set; }
}
public class Class1
{
private const string URL = "https://sub.domain.com/objects.json";
private string urlParameters = "?api_key=123";
static void Main(string[] args)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(URL);
// Add an Accept header for JSON format.
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
// List data response.
HttpResponseMessage response = client.GetAsync(urlParameters).Result; // Blocking call! Program will wait here until a response is received or a timeout occurs.
if (response.IsSuccessStatusCode)
{
// Parse the response body.
var dataObjects = response.Content.ReadAsAsync<IEnumerable<DataObject>>().Result; //Make sure to add a reference to System.Net.Http.Formatting.dll
foreach (var d in dataObjects)
{
Console.WriteLine("{0}", d.Name);
}
}
else
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
}
// Make any other calls using HttpClient here.
// Dispose once all HttpClient calls are complete. This is not necessary if the containing object will be disposed of; for example in this case the HttpClient instance will be disposed automatically when the application terminates so the following call is superfluous.
client.Dispose();
}
}
}
If you plan on making multiple requests, you should re-use your HttpClient instance. See this question and its answers for more details on why a using statement was not used on the HttpClient instance in this case: Do HttpClient and HttpClientHandler have to be disposed between requests?
For more details, including other examples, see Call a Web API From a .NET Client (C#)

When building apps for 32-bit or 64-bit platform (My experience is with Visual Studio 2010), don't rely on the Configuration Manager to set the correct platform for the executable. Even if the CM has x86 selected for the application, check the project properties (Build tab): it might still say "Any CPU" there. And if you run an "Any CPU" executable on a 64-bit platform, it will run in 64-bit mode and refuse to load your accompanying DLLs that were built for the x86 platform.
Consider using System.Windows.Forms.Timer
instead of System.Threading.Timer
for a GUI application, for timers that are based on the Windows message queue instead of on dedicated threads or the thread pool.
In your scenario, for the purpose of periodic updates of UI, it seems particularly appropriate since you don't really have a background work or long calculation to perform. You just want to do periodic small tasks that have to happen on the UI thread anyway.
I came across System.Runtime.InteropServices.COMException
while opening a project solution. Sometimes user doesn't have enough priveleges to run some COM
Methods. I ran Visual Studio as Administrator and the exception was gone.
It seems to be a long-running framework process for debugging (to decrease load times?). I discovered that when you start your application twice from the debugger often the same vshost.exe process will be used. It just unloads all user-loaded DLLs first. This does odd things if you are fooling around with API hooks from managed processes.
This is probably not the solution for everyone, but it was for me.
If you are using NVM, you might not have enabled the right version of node for the code you are running. After you reboot, your default version of node changes back to the system default.
Was running into this when working with react-native which had been working fine. Just use nvm to use the right version of node to solve this problem.
Range("C1:C10").Formula = "=A1+B1"
Simple as that.
It autofills (FillDown) the range with the formula.
If there is an object with 8 methods and you have a test where you want to call 7 real methods and stub one method you have two options:
spy
you have to set it up by stubbing one methodThe official documentation on doCallRealMethod
recommends using a spy for partial mocks.
See also javadoc spy(Object) to find out more about partial mocks. Mockito.spy() is a recommended way of creating partial mocks. The reason is it guarantees real methods are called against correctly constructed object because you're responsible for constructing the object passed to spy() method.
It depends on how you declare your table. NULL would not be allowed in:
create table MyTable (col1 datetime NOT NULL);
But it would be allowed in:
create table MyTable (col1 datetime NULL);
The second is the default, so someone must've actively decided that the column should not be nullable.
Maybe silly, but check that you inline script is AFTER you include the script tags.
Alternatively if you want to grab the private and public keys from a PuTTY formated key file you can use puttygen
on *nix systems. For most apt-based systems puttygen
is part of the putty-tools
package.
Outputting a private key from a PuTTY formated keyfile:
$ puttygen keyfile.pem -O private-openssh -o avdev.pvk
For the public key:
$ puttygen keyfile.pem -L
go to the directory of .Net framework and register their the respective dll with Regsvr32.exe white space dll path.
You're looking for:
.is(':visible')
Although you should probably change your selector to use jQuery considering you're using it in other places anyway:
if($('#testElement').is(':visible')) {
// Code
}
It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible')
on the child will return false
(which makes sense).
:visible
has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible
):
Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!
Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.
Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle()
:
function toggleTestElement() {
$('#testElement').fadeToggle('fast');
}
Here's a neat trick in Sublime Text 2 or 3 to convert your indentation spacing in a document.
TL;DR:
Converting from 2 spaces to 4 spaces:
Ensure tab width is set to 2. Convert your 2-space indentation to tabs, switch to tab width 4, and then convert the indentation back to spaces.
The detailed description:
Go to:
View -> Indentation
It should read:
Indent using spaces [x]
Tab width: 2
Select:
Convert Indentation to Tabs
Then Select:
Tab width: 4
Convert Indentation to Spaces
Done.
You're looking for the indexOf function:
if (str.indexOf("are") >= 0){//Do stuff}
This work for me
$('#mySelect option:contains(' + value + ')').attr('selected', 'selected');
I got this along with the message
Invalid drive specification
when copying to a network share without specifying the drive name, e.g.
xcopy . \\localhost
where
xcopy . \\localhost\share
was expected
HostListener should be the proper way to bind event into your component:
@Component({
selector: 'your-element'
})
export class YourElement {
@HostListener('click', ['$event']) onClick(event) {
console.log('component is clicked');
console.log(event);
}
}

I'm not entirely sure that I've understood the question because this is a fairly straightforward answer, but here goes... :)
Have you tried setting the overflow property of the container to visible or auto?
#some_div {
height:100%;
background:black;
overflow: visible;
}
Adding that should push the black container to whatever size your dynamic container requires. I prefer visible to auto because auto seems to come with scroll bars...
Replacement for Apple's Reachability re-written in Swift with closures, inspired by tonymillion: https://github.com/ashleymills/Reachability.swift
Drop the file Reachability.swift
into your project. Alternatively, use CocoaPods or Carthage - See the Installation section of the project's README.
Get notifications about network connectivity:
//declare this property where it won't go out of scope relative to your listener
let reachability = Reachability()!
reachability.whenReachable = { reachability in
if reachability.isReachableViaWiFi {
print("Reachable via WiFi")
} else {
print("Reachable via Cellular")
}
}
reachability.whenUnreachable = { _ in
print("Not reachable")
}
do {
try reachability.startNotifier()
} catch {
print("Unable to start notifier")
}
and for stopping notifications
reachability.stopNotifier()
I use this query in order to retrieve the server name of my Oracle database.
SELECT program FROM v$session WHERE program LIKE '%(PMON)%';
On Windows, create a batch file with the following line in it:
start cmd /k "C:\Anaconda3\Scripts\activate.bat C:\Anaconda3 & activate env"
The first path contained in quotes is the path to the activate.bat file in the Anaconda installation. The path on your system might be different. The name following the activate command of course should be your desired environment name.
Then run the batch file when you need to open an Anaconda prompt.
You need to use WITH ROLLBACK IMMEDIATE
to boot other conections out with no regards to what or who is is already using it.
Or use WITH NO_WAIT
to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details
Here is an example of iterating over a pd.DataFrame
grouped by the column atable
. For this sample, "create" statements for an SQL database are generated within the for
loop:
import pandas as pd
df1 = pd.DataFrame({
'atable': ['Users', 'Users', 'Domains', 'Domains', 'Locks'],
'column': ['col_1', 'col_2', 'col_a', 'col_b', 'col'],
'column_type':['varchar', 'varchar', 'int', 'varchar', 'varchar'],
'is_null': ['No', 'No', 'Yes', 'No', 'Yes'],
})
df1_grouped = df1.groupby('atable')
# iterate over each group
for group_name, df_group in df1_grouped:
print('\nCREATE TABLE {}('.format(group_name))
for row_index, row in df_group.iterrows():
col = row['column']
column_type = row['column_type']
is_null = 'NOT NULL' if row['is_null'] == 'NO' else ''
print('\t{} {} {},'.format(col, column_type, is_null))
print(");")
0.0.0.0/0
for all IPv4 addresses
::0/0
for all IPv6 addresses
all
to match any IP address
samehost
to match any of the server's own IP addresses
samenet
to match any address in any subnet that the server is directly connected to.
e.g.
host all all 0.0.0.0/0 md5
Use cbind
e.g.
df <- data.frame(b = runif(6), c = rnorm(6))
cbind(a = 0, df)

Try to use DateTime.ParseExact method, in which you can specify both of datetime mask and original parsed string. You can read about it here: MSDN: DateTime.ParseExact
If you have a ConstraintLayout
with some size, and a child View
with some smaller size, you can achieve centering by constraining the child's two edges to the same two edges of the parent. That is, you can write:
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
or
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
Because the view is smaller, these constraints are impossible. But ConstraintLayout
will do the best it can, and each constraint will "pull" at the child view equally, thereby centering it.
This concept works with any target view, not just the parent.
Below is XML that achieves your desired UI with no nesting of views and no Guideline
s (though guidelines are not inherently evil).

In order to use special characters, such as '>' on Windows with echo, you need to place a special escape character before it.
For instance
echo A->B
will not work since '>' has to be escaped by '^':
echo A-^>B
See also escape sequences.
There is a short batch file, which prints a basic set of special character and their escape sequences.
A possible soluttion that requires tweaking, but is very flexible is to use one of \big
, \Big
, \bigg
,\Bigg
in front of your division sign - these will make it progressively larger. For your formula, I think
$\frac{a_1}{a_2} \Big/ \frac{b_1}{b_2}$
looks nicer than \middle\
which is automatically sized and IMHO is a bit too large.
I had this issue and i fixed with the code below.
@Configuration
open class JacksonMapper {
@Bean
open fun mapper(): ObjectMapper {
val mapper = ObjectMapper()
...
mapper.registerModule(KotlinModule())
return mapper
}
}
From http://www.sqlite.org/lang_createtable.html:
CREATE TABLE IF NOT EXISTS some_table (id INTEGER PRIMARY KEY AUTOINCREMENT, ...);
max
is built in function which takes first argument an iterable
(like list or tuple)
keyword argument key
has it's default value None
but it accept function to evaluate, consider it as wrapper which evaluates iterable based on function
Consider this example dictionary:
d = {'aim':99, 'aid': 45, 'axe': 59, 'big': 9, 'short': 995, 'sin':12, 'sword':1, 'friend':1000, 'artwork':23}
Ex:
>>> max(d.keys())
'sword'
As you can see if you only pass the iterable without kwarg(a function to key
) it is returning maximum value of key(alphabetically)
Ex. Instead of finding max value of key alphabetically you might need to find max key by length of key:
>>>max(d.keys(), key=lambda x: len(x))
'artwork'
in this example lambda function is returning length of key which will be iterated hence while evaluating values instead of considering alphabetically it will keep track of max length of key and returns key which has max length
Ex.
>>> max(d.keys(), key=lambda x: d[x])
'friend'
in this example lambda function is returning value of corresponding dictionary key which has maximum value
You can also try ExcelPython which allows you to manipulate Python object and call code from VBA.
for (var i in conf) {
val = conf[i];
console.log(val.path);
}

Use this:
mysqli_query($this->db_link, $query) or die(mysqli_error($this->db_link));
# mysqli_query($link,$query) returns 0 if there's an error.

You can also use this to print the error code.
echo mysqli_errno($this->db_link);
I write a code to read file line by line to meet my demand which different line have different data type follow articles: read-line-by-line-of-a-file-in-r and determining-number-of-linesrecords. And it should be a better solution for big file, I think. My R version (3.3.2).
con = file("pathtotargetfile", "r")
readsizeof<-2 # read size for one step to caculate number of lines in file
nooflines<-0 # number of lines
while((linesread<-length(readLines(con,readsizeof)))>0) # calculate number of lines. Also a better solution for big file
nooflines<-nooflines+linesread
con = file("pathtotargetfile", "r") # open file again to variable con, since the cursor have went to the end of the file after caculating number of lines
typelist = list(0,'c',0,'c',0,0,'c',0) # a list to specific the lines data type, which means the first line has same type with 0 (e.g. numeric)and second line has same type with 'c' (e.g. character). This meet my demand.
for(i in 1:nooflines) {
tmp <- scan(file=con, nlines=1, what=typelist[[i]], quiet=TRUE)
print(is.vector(tmp))
print(tmp)
}
close(con)
You just need to get selenium package imported, that you can do from command prompt using the command
pip install selenium
When you have to use it in any IDE just import this package, no other documentation required to be imported
For Eg :
import selenium
print(selenium.__filepath__)
This is just a general command you may use in starting to check the filepath of selenium
Look in the \application\config\config.php
file, there is a variable named index_page
It should look like this
$config['index_page'] = "index.php";
change it to
$config['index_page'] = "";
Then as mentioned you also need to add a rewrite rule to the .htaccess
file like this:
RewriteEngine on
RewriteCond $1 !^(index\\.php|resources|robots\\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
It work for me, hope you too.
The introduction of some new testing facilities in Spring 4.2.RC1 lets one write Spring integration tests that don't rely on the SpringJUnit4ClassRunner
. Check out this part of the documentation.
In your case you could write your Spring integration test and still use mocks like this:
@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration("test-app-ctx.xml")
public class FooTest {
@ClassRule
public static final SpringClassRule SPRING_CLASS_RULE = new SpringClassRule();
@Rule
public final SpringMethodRule springMethodRule = new SpringMethodRule();
@Autowired
@InjectMocks
TestTarget sut;
@Mock
Foo mockFoo;
@Test
public void someTest() {
// ....
}
}
When setup a job in new windows you have two fields "program/script" and "Start in(Optional)". Put program name in first and program location in second. If you will not do that and your program start not in directory with exe, it will not find files that are located in it.

I was so exasperated by many misleading articles and answers that I wrote my own RSS reader: https://gouessej.wordpress.com/2020/06/28/comment-creer-un-lecteur-rss-en-javascript-how-to-create-a-rss-reader-in-javascript/
You can use AJAX requests to fetch the RSS files but it will work if and only if you use a CORS proxy. I'll try to write my own CORS proxy to give you a more robust solution. In the meantime, it works, I deployed it on my server under Debian Linux.
My solution doesn't use JQuery, I use only plain Javascript standard APIs with no third party libraries and it's supposed to work even with Microsoft Internet Explorer 11.
This is no better than other answers, but is one more way to get the job done in a file without spaces (see comments). I find that I often need one-liners to dig through lists in text files without the extra step of using separate script files.
for word in $(cat peptides.txt); do echo $word; done
This format allows me to put it all in one command-line. Change the "echo $word" portion to whatever you want and you can issue multiple commands separated by semicolons. The following example uses the file's contents as arguments into two other scripts you may have written.
for word in $(cat peptides.txt); do cmd_a.sh $word; cmd_b.py $word; done
Or if you intend to use this like a stream editor (learn sed) you can dump the output to another file as follows.
for word in $(cat peptides.txt); do cmd_a.sh $word; cmd_b.py $word; done > outfile.txt
I've used these as written above because I have used text files where I've created them with one word per line. (See comments) If you have spaces that you don't want splitting your words/lines, it gets a little uglier, but the same command still works as follows:
OLDIFS=$IFS; IFS=$'\n'; for line in $(cat peptides.txt); do cmd_a.sh $line; cmd_b.py $line; done > outfile.txt; IFS=$OLDIFS
This just tells the shell to split on newlines only, not spaces, then returns the environment back to what it was previously. At this point, you may want to consider putting it all into a shell script rather than squeezing it all into a single line, though.
Best of luck!
$url="http://example.com";
$html = file_get_contents($url);
$doc = new DOMDocument();
@$doc->loadHTML($html);
$tags = $doc->getElementsByTagName('img');
foreach ($tags as $tag) {
echo $tag->getAttribute('src');
}
In C++ (but not plain C), it's perfectly legal to typedef a type twice, so long as both definitions are completely identical:
// foo.h
struct A{};
typedef A *PA;
// bar.h
struct A; // forward declare A
typedef A *PA;
void func(PA x);
// baz.cc
#include "bar.h"
#include "foo.h"
// We've now included the definition for PA twice, but it's ok since they're the same
...
A x;
func(&x);
I wanted to use wildcards to plot multiple files often placed in different directories, while working from any directory. The solution i found was to create the following function in ~/.bashrc
plo () {
local arg="w l"
local str="set term wxt size 900,500 title 'wild plotting'
set format y '%g'
set logs
plot"
while [ $# -gt 0 ]
do str="$str '$1' $arg,"
shift
done
echo "$str" | gnuplot -persist
}
and use it e.g. like plo *.dat ../../dir2/*.out
, to plot all .dat
files in the current directory and all .out
files in a directory that happens to be a level up and is called dir2
.
You need to use the scrollTop
property.
document.getElementById('box').scrollTop
Starting with Go 1.16, use os.ReadFile
to load the file to memory, use os.WriteFile
to write to a file from memory.
Be careful with the os.ReadFile
because it reads the whole file into memory.
package main
import "os"
func main() {
b, err := os.ReadFile("input.txt")
if err != nil {
log.Fatal(err)
}
// `data` contains everything your file does
// This writes it to the Standard Out
os.Stdout.Write(data)
// You can also write it to a file as a whole
err = os.WriteFile("destination.txt", b, 0644)
if err != nil {
log.Fatal(err)
}
}
you can just set the selectedBackgroundView of the cell to be backgroundColor=x.
Now any time you tap on cell his selected mode will change automatically and will couse to the background color to change to x.
There is no hostname verification in standard Java SSL sockets or indeed SSL, so that's why you can't set it at that level. Hostname verification is part of HTTPS (RFC 2818): that's why it manifests itself as javax.net.ssl.HostnameVerifier, which is applied to an HttpsURLConnection.
Starting from Scala 3, there is now enum keyword which can represent a set of constants (and other use cases)
enum Color:
case Red, Green, Blue
scala> val red = Color.Red
val red: Color = Red
scala> red.ordinal
val res0: Int = 0
You need to loop through and parse/convert the elements in your array, like this:
var result_string = 'a,b,c,d|1,2,3,4',
result = result_string.split("|"),
alpha = result[0],
count = result[1],
count_array = count.split(",");
for(var i=0; i<count_array.length;i++) count_array[i] = +count_array[i];
//now count_array contains numbers
You can test it out here. If the +
, is throwing, think of it as:
for(var i=0; i<count_array.length;i++) count_array[i] = parseInt(count_array[i], 10);
Put the code so it executes after the elements are defined, either with a DOM ready callback or place the source under the elements in the HTML.
document.getElementById()
returns null
if the element couldn't be found. Property assignment can only occur on objects. null
is not an object (contrary to what typeof
says).
You can use css with relative/absolute positioning if you want it responsive. Plus it can handle easily the multi-line.
https://jsfiddle.net/mgyp0jkk/
<div class="relative">
<canvas id="myChart"></canvas>
<div class="absolute-center text-center">
<p>Some text</p>
<p>Some text</p>
</div>
</div>
If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward. If you started with a concrete type and you decided to change to another one, even if it uses the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type.
First, lose that call to int
- you're converting a string of characters to an integer, which isn't what you want (you want to treat each character as its own number). Change:
inp = int(input("Enter a number:"))
to:
inp = input("Enter a number:")
Now that inp
is a string of digits, you can loop over it, digit by digit.
Next, assign some initial value to n
-- as you code stands right now, you'll get a NameError
since you never initialize it. Presumably you want n = 0
before the for
loop.
Next, consider the difference between a character and an integer again. You now have:
n = n + i;
which, besides the unnecessary semicolon (Python is an indentation-based syntax), is trying to sum the character i to the integer n -- that won't work! So, this becomes
n = n + int(i)
to turn character '7'
into integer 7
, and so forth.
In my code I have no direct access to the 'preparedStatement' so I cannot use batch, I just pass it the query and a list of parameters. The trick however is to create a variable length insert statement, and a LinkedList of parameters. The effect is the same as the top example, with variable parameter input length.See below (error checking omitted). Assuming 'myTable' has 3 updatable fields: f1, f2 and f3
String []args={"A","B","C", "X","Y","Z" }; // etc, input list of triplets
final String QUERY="INSERT INTO [myTable] (f1,f2,f3) values ";
LinkedList params=new LinkedList();
String comma="";
StringBuilder q=QUERY;
for(int nl=0; nl< args.length; nl+=3 ) { // args is a list of triplets values
params.add(args[nl]);
params.add(args[nl+1]);
params.add(args[nl+2]);
q.append(comma+"(?,?,?)");
comma=",";
}
int nr=insertIntoDB(q, params);
in my DBInterface class I have:
int insertIntoDB(String query, LinkedList <String>params) {
preparedUPDStmt = connectionSQL.prepareStatement(query);
int n=1;
for(String x:params) {
preparedUPDStmt.setString(n++, x);
}
int updates=preparedUPDStmt.executeUpdate();
return updates;
}
When you do a cmp a,b
, the flags are set as if you had calculated a - b
.
Then the jmp
-type instructions check those flags to see if the jump should be made.
In other words, the first block of code you have (with my comments added):
cmp al,dl ; set flags based on the comparison
jg label1 ; then jump based on the flags
would jump to label1
if and only if al
was greater than dl
.
You're probably better off thinking of it as al > dl
but the two choices you have there are mathematically equivalent:
al > dl
al - dl > dl - dl (subtract dl from both sides)
al - dl > 0 (cancel the terms on the right hand side)
You need to be careful when using jg
inasmuch as it assumes your values were signed. So, if you compare the bytes 101 (101 in two's complement) with 200 (-56 in two's complement), the former will actually be greater. If that's not what was desired, you should use the equivalent unsigned comparison.
See here for more detail on jump selection, reproduced below for completeness. First the ones where signed-ness is not appropriate:
+--------+------------------------------+-------------+--------------------+
|Instr | Description | signed-ness | Flags |
+--------+------------------------------+-------------+--------------------+
| JO | Jump if overflow | | OF = 1 |
+--------+------------------------------+-------------+--------------------+
| JNO | Jump if not overflow | | OF = 0 |
+--------+------------------------------+-------------+--------------------+
| JS | Jump if sign | | SF = 1 |
+--------+------------------------------+-------------+--------------------+
| JNS | Jump if not sign | | SF = 0 |
+--------+------------------------------+-------------+--------------------+
| JE/ | Jump if equal | | ZF = 1 |
| JZ | Jump if zero | | |
+--------+------------------------------+-------------+--------------------+
| JNE/ | Jump if not equal | | ZF = 0 |
| JNZ | Jump if not zero | | |
+--------+------------------------------+-------------+--------------------+
| JP/ | Jump if parity | | PF = 1 |
| JPE | Jump if parity even | | |
+--------+------------------------------+-------------+--------------------+
| JNP/ | Jump if no parity | | PF = 0 |
| JPO | Jump if parity odd | | |
+--------+------------------------------+-------------+--------------------+
| JCXZ/ | Jump if CX is zero | | CX = 0 |
| JECXZ | Jump if ECX is zero | | ECX = 0 |
+--------+------------------------------+-------------+--------------------+
Then the unsigned ones:
+--------+------------------------------+-------------+--------------------+
|Instr | Description | signed-ness | Flags |
+--------+------------------------------+-------------+--------------------+
| JB/ | Jump if below | unsigned | CF = 1 |
| JNAE/ | Jump if not above or equal | | |
| JC | Jump if carry | | |
+--------+------------------------------+-------------+--------------------+
| JNB/ | Jump if not below | unsigned | CF = 0 |
| JAE/ | Jump if above or equal | | |
| JNC | Jump if not carry | | |
+--------+------------------------------+-------------+--------------------+
| JBE/ | Jump if below or equal | unsigned | CF = 1 or ZF = 1 |
| JNA | Jump if not above | | |
+--------+------------------------------+-------------+--------------------+
| JA/ | Jump if above | unsigned | CF = 0 and ZF = 0 |
| JNBE | Jump if not below or equal | | |
+--------+------------------------------+-------------+--------------------+
And, finally, the signed ones:
+--------+------------------------------+-------------+--------------------+
|Instr | Description | signed-ness | Flags |
+--------+------------------------------+-------------+--------------------+
| JL/ | Jump if less | signed | SF <> OF |
| JNGE | Jump if not greater or equal | | |
+--------+------------------------------+-------------+--------------------+
| JGE/ | Jump if greater or equal | signed | SF = OF |
| JNL | Jump if not less | | |
+--------+------------------------------+-------------+--------------------+
| JLE/ | Jump if less or equal | signed | ZF = 1 or SF <> OF |
| JNG | Jump if not greater | | |
+--------+------------------------------+-------------+--------------------+
| JG/ | Jump if greater | signed | ZF = 0 and SF = OF |
| JNLE | Jump if not less or equal | | |
+--------+------------------------------+-------------+--------------------+
Another solution could be following:
This is how you use it:
final Opt<String> opt = Opt.of("I'm a cool text");
opt.ifPresent()
.apply(s -> System.out.printf("Text is: %s\n", s))
.elseApply(() -> System.out.println("no text available"));
Or in case you in case of the opposite use case is true:
final Opt<String> opt = Opt.of("This is the text");
opt.ifNotPresent()
.apply(() -> System.out.println("Not present"))
.elseApply(t -> /*do something here*/);
This are the ingredients:
The "cosmetically" enhanced Function interface.
@FunctionalInterface
public interface Fkt<T, R> extends Function<T, R> {
default R elseApply(final T t) {
return this.apply(t);
}
}
And the Optional wrapper class for enhancement:
public class Opt<T> {
private final Optional<T> optional;
private Opt(final Optional<T> theOptional) {
this.optional = theOptional;
}
public static <T> Opt<T> of(final T value) {
return new Opt<>(Optional.of(value));
}
public static <T> Opt<T> of(final Optional<T> optional) {
return new Opt<>(optional);
}
public static <T> Opt<T> ofNullable(final T value) {
return new Opt<>(Optional.ofNullable(value));
}
public static <T> Opt<T> empty() {
return new Opt<>(Optional.empty());
}
private final BiFunction<Consumer<T>, Runnable, Void> ifPresent = (present, notPresent) -> {
if (this.optional.isPresent()) {
present.accept(this.optional.get());
} else {
notPresent.run();
}
return null;
};
private final BiFunction<Runnable, Consumer<T>, Void> ifNotPresent = (notPresent, present) -> {
if (!this.optional.isPresent()) {
notPresent.run();
} else {
present.accept(this.optional.get());
}
return null;
};
public Fkt<Consumer<T>, Fkt<Runnable, Void>> ifPresent() {
return Opt.curry(this.ifPresent);
}
public Fkt<Runnable, Fkt<Consumer<T>, Void>> ifNotPresent() {
return Opt.curry(this.ifNotPresent);
}
private static <X, Y, Z> Fkt<X, Fkt<Y, Z>> curry(final BiFunction<X, Y, Z> function) {
return (final X x) -> (final Y y) -> function.apply(x, y);
}
}
This should do the trick and could serve as a basic template how to deal with such requirements.
The basic idea here is following. In a non functional style programming world you would probably implement a method taking two parameter where the first is a kind of runnable code which should be executed in case the value is available and the other parameter is the runnable code which should be run in case the value is not available. For the sake of better readability, you can use curring to split the function of two parameter in two functions of one parameter each. This is what I basically did here.
Hint: Opt also provides the other use case where you want to execute a piece of code just in case the value is not available. This could be done also via Optional.filter.stuff but I found this much more readable.
Hope that helps!
Good programming :-)
Its Working for me ..... add hint color in TextInputLayout
<android.support.design.widget.TextInputLayout
android:textColorHint="#ffffff"
android:id="@+id/input_layout_password"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/edtTextPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:hint="Password"
android:inputType="textPassword"
android:singleLine="true"
/>
</android.support.design.widget.TextInputLayout>
It's simpler if you modify your HTML a little bit:
<label for="first_name">First Name</label>
<input type="text" id="name" name="name" />
<label for="surname">Surname</label>
<input type="text" id="surname" name="surname" />
<label for="firstname">Firstname</label>
<input type="text" id="firstname" name="firstname" disabled="disabled" />
then it's relatively simple
$(document).ready(function() {
$('#name').change(function() {
$('#firstname').val($('#name').val());
});
});
Product Version
may be preferred if you're using versioning via GitVersion or other versioning software.
To get this from within your class library you can call System.Diagnostics.FileVersionInfo.ProductVersion
:
using System.Diagnostics;
using System.Reflection;
//...
var assemblyLocation = Assembly.GetExecutingAssembly().Location;
var productVersion = FileVersionInfo.GetVersionInfo(assemblyLocation).ProductVersion
Types are dependent to your initialization:
var IsLoggedIn1 = "true"; //string
var IsLoggedIn2 = 1; //integer
var IsLoggedIn3 = true; //bool
But take a look at this example:
var IsLoggedIn1 = "true"; //string
IsLoggedIn1 = true; //now your variable is a boolean
Your variables' type depends on the assigned value in JavaScript.
You should avoid setting LD_LIBRARY_PATH
in your .bashrc
. See "Why LD_LIBRARY_PATH is bad
" for more information.
Use the linker option -rpath while linking so that the dynamic linker knows where to find libsync.so
during runtime.
gcc ... -Wl,-rpath /path/to/library -L/path/to/library -lsync -o sync_test
Another way would be to use a wrapper like this
#!/bin/bash
LD_LIBRARY_PATH=/path/to/library sync_test "$@"
If sync_test
starts any other programs, they might end up using the libs in /path/to/library
which may or may not be intended.
Here is my solution and it's also working, when element shows into the viewport
var counterTeaserL = $('.go-counterTeaser');
var winHeight = $(window).height();
if (counterTeaserL.length) {
var firEvent = false,
objectPosTop = $('.go-counterTeaser').offset().top;
//when element shows at bottom
var elementViewInBottom = objectPosTop - winHeight;
$(window).on('scroll', function() {
var currentPosition = $(document).scrollTop();
//when element position starting in viewport
if (currentPosition > elementViewInBottom && firEvent === false) {
firEvent = true;
animationCounter();
}
});
}
//counter function will animate by using external js also add seprator "."
function animationCounter(){
$('.numberBlock h2').each(function () {
var comma_separator_number_step = $.animateNumber.numberStepFactories.separator('.');
var counterValv = $(this).text();
$(this).animateNumber(
{
number: counterValv,
numberStep: comma_separator_number_step
}
);
});
}

Windows dll error 126 can have many root causes. The most useful methods I have found to debug this are:
All POSIX operating systems have 3 streams: stdin, stdout, and stderr. stdin is the input, which can accept the stdout or stderr. stdout is the primary output, which is redirected with >
, >>
, or |
. stderr is the error output, which is handled separately so that any exceptions do not get passed to a command or written to a file that it might break; normally, this is sent to a log of some kind, or dumped directly, even when the stdout is redirected. To redirect both to the same place, use:
command &> /some/file
EDIT: thanks to Zack for pointing out that the above solution is not portable--use instead:
*command* > file 2>&1
If you want to silence the error, do:
*command* 2> /dev/null
def list_test (L):
if L is None : print('list is None')
elif not L : print('list is empty')
else: print('list has %d elements' % len(L))
list_test(None)
list_test([])
list_test([1,2,3])
It is sometimes good to test for None
and for emptiness separately as those are two different states. The code above produces the following output:
list is None
list is empty
list has 3 elements
Although it's worth nothing that None
is falsy. So if you don't want to separate test for None
-ness, you don't have to do that.
def list_test2 (L):
if not L : print('list is empty')
else: print('list has %d elements' % len(L))
list_test2(None)
list_test2([])
list_test2([1,2,3])
produces expected
list is empty
list is empty
list has 3 elements
As mentioned in other answers, It takes forever because the size of cocoapods master repo is huge. This time can be reduced using the following steps.
1) Create a private specs file path on your github repository. Provide this path https://github.com/yourpathForspecs.git' as a source in your podfile.
2) identify ALL the repositories You need and their dependencies( mentioned in the podspec.json file on cocoapods for these repositories) and get their podspec.json files from cocoapods. add these podspec.json files with their folder ( say the latest version folder for bolts) in this specs repository.
3) remove the source 'https://github.com/CocoaPods/Specs.git' in the podfile
4) pod update
This will take significantly less time as this requires fetching and downloading just the pods you need instead of whole cocoapods repository. In My case it reduced the pod update time from 15-20 mins on average to 3-4 mins at most.
Assuming that < 600px means mobile to you, you can use this observable and subscribe to it:
First we need the current window size. So we create an observable which only emits a single value: the current window size.
initial$ = Observable.of(window.innerWidth > 599 ? false : true);
Then we need to create another observable, so that we know when the window size was changed. For this we can use the "fromEvent" operator. To learn more about rxjs`s operators please visit: rxjs
resize$ = Observable.fromEvent(window, 'resize').map((event: any) => {
return event.target.innerWidth > 599 ? false : true;
});
Merg these two streams to receive our observable:
mobile$ = Observable.merge(this.resize$, this.initial$).distinctUntilChanged();
Now you can subscribe to it like this:
mobile$.subscribe((event) => { console.log(event); });
Remember to unsubscribe :)
I had this issue after migrating from spring-boot-starter-data-jpa
ver. 1.5.7 to 2.0.2 (from old hibernate to hibernate 5.2). In my @Configuration
class I injected entityManagerFactory
and transactionManager
.
//I've got my data source defined in application.yml config file,
//so there is no need to configure it from java.
@Autowired
DataSource dataSource;
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
//JpaVendorAdapteradapter can be autowired as well if it's configured in application properties.
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(false);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
//Add package to scan for entities.
factory.setPackagesToScan("com.company.domain");
factory.setDataSource(dataSource);
return factory;
}
@Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory);
return txManager;
}
Also remember to add hibernate-entitymanager dependency to pom.xml otherwise EntityManagerFactory won't be found on classpath:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.0.12.Final</version>
</dependency>
Build up a JavaScript data structure with the required information, then turn it into the json string at the end.
Based on what I think you're doing, try something like this:
var result = [];
for (var name in goals) {
if (goals.hasOwnProperty(name)) {
result.push({name: name, goals: goals[name]});
}
}
res.contentType('application/json');
res.send(JSON.stringify(result));
or something along those lines.
To add onto the other answers that state that you might wish store variables in the application scope, for any long-running threads or other objects that need binding to your application where you are NOT using an activity (application is not an activity).. such as not being able to request a binded service.. then binding to the application instance is preferred. The only obvious warning with this approach is that the objects live for as long as the application is alive, so more implicit control over memory is required else you'll encounter memory-related problems like leaks.
Something else you may find useful is that in the order of operations, the application starts first before any activities. In this timeframe, you can prepare any necessary housekeeping that would occur before your first activity if you so desired.
2018-10-19 11:31:55.246 8643-8643/: application created
2018-10-19 11:31:55.630 8643-8643/: activity created
<input type="image" name="your_image_name" src="your_image_url.png" />
This will send the your_image_name.x
and your_image_name.y
values as it submits the form, which are the x and y coordinates of the position the user clicked the image.
The new cv2
interface for Python integrates numpy arrays into the OpenCV framework, which makes operations much simpler as they are represented with simple multidimensional arrays. For example, your question would be answered with:
import cv2 # Not actually necessary if you just want to create an image.
import numpy as np
blank_image = np.zeros((height,width,3), np.uint8)
This initialises an RGB-image that is just black. Now, for example, if you wanted to set the left half of the image to blue and the right half to green , you could do so easily:
blank_image[:,0:width//2] = (255,0,0) # (B, G, R)
blank_image[:,width//2:width] = (0,255,0)
If you want to save yourself a lot of trouble in future, as well as having to ask questions such as this one, I would strongly recommend using the cv2
interface rather than the older cv
one. I made the change recently and have never looked back. You can read more about cv2
at the OpenCV Change Logs.
If you look at Twitter's own container-app.html demo on GitHub, you'll get some ideas on using borders with their grid.
For example, here's the extracted part of the building blocks to their 940-pixel wide 16-column grid system:
.row {
zoom: 1;
margin-left: -20px;
}
.row > [class*="span"] {
display: inline;
float: left;
margin-left: 20px;
}
.span4 {
width: 220px;
}
To allow for borders on specific elements, they added embedded CSS to the page that reduces matching classes by enough amount to account for the border(s).
For example, to allow for the left border on the sidebar, they added this CSS in the <head>
after the the main <link href="../bootstrap.css" rel="stylesheet">
.
.content .span4 {
margin-left: 0;
padding-left: 19px;
border-left: 1px solid #eee;
}
You'll see they've reduced padding-left
by 1px
to allow for the addition of the new left border. Since this rule appears later in the source order, it overrides any previous or external declarations.
I'd argue this isn't exactly the most robust or elegant approach, but it illustrates the most basic example.
s[0:"s".index("&")]
what does this do:
Quote from Jeff Handley's Blog Post on Validation Objects and Properties with Validator:
When validating an object, the following process is applied in Validator.ValidateObject:
- Validate property-level attributes
- If any validators are invalid, abort validation returning the failure(s)
- Validate the object-level attributes
- If any validators are invalid, abort validation returning the failure(s)
- If on the desktop framework and the object implements IValidatableObject, then call its Validate method and return any failure(s)
This indicates that what you are attempting to do won't work out-of-the-box because the validation will abort at step #2. You could try to create attributes that inherit from the built-in ones and specifically check for the presence of an enabled property (via an interface) before performing their normal validation. Alternatively, you could put all of the logic for validating the entity in the Validate
method.
You also could take a look a the exact implemenation of Validator
class here
For those looking for OBJC solution, to be added in App Delegate didFinishLaunchingWithOptions method:
[[UINavigationBar appearance] setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
[UINavigationBar appearance].shadowImage = [UIImage new];
[UINavigationBar appearance].backgroundColor = [UIColor clearColor];
[UINavigationBar appearance].translucent = YES;
cursor.rowcount
will usually be set to 0.
If, however, you are running a statement that would never return a result set (such as INSERT
without RETURNING
, or SELECT ... INTO
), then you do not need to call .fetchall()
; there won't be a result set for such statements. Calling .execute()
is enough to run the statement.
Note that database adapters are also allowed to set the rowcount to -1
if the database adapter can't determine the exact affected count. See the PEP 249 Cursor.rowcount
specification:
The attribute is
-1
in case no.execute*()
has been performed on the cursor or the rowcount of the last operation is cannot be determined by the interface.
The sqlite3
library is prone to doing this. In all such cases, if you must know the affected rowcount up front, execute a COUNT()
select in the same transaction first.
You need to use multiple rules to implement OR-like semantics, since matches are always AND-ed together within a rule. Alternatively, you can do matching against port-indexing ipsets (ipset create blah bitmap:port
).
Working fine for me.

This finds the duplicate key in the first array and merges the second arrays object having the same key value. If no value is found in the second array, it uses the original object. As you can see, lang is only found once in the result set; having german for the value.
We use @Temporal annotation to insert date, time or both in database table.Using TemporalType we can insert data, time or both int table.
@Temporal(TemporalType.DATE) // insert date
@Temporal(TemporalType.TIME) // insert time
@Temporal(TemporalType.TIMESTAMP) // insert both time and date.
var myNumber: number = 1200;_x000D_
//convert to hexadecimal value_x000D_
console.log(myNumber.toString(16)); //will return 4b0_x000D_

The best way would be to use the performance hooks
module. Although unstable, you can mark
specific areas of your code and measure
the duration
between marked areas.
const { performance, PerformanceObserver } = require('perf_hooks');
const measures = []
const obs = new PerformanceObserver(list => measures.push(...list.getEntries()));
obs.observe({ entryTypes: ['measure'] });
const getEntriesByType = cb => cb(measures);
const doSomething = val => {
performance.mark('beginning of the process');
val *= 2;
performance.mark('after multiplication');
performance.measure('time taken', 'beginning of the process', 'after multiplication');
getEntriesByType(entries => {
entries.forEach(entry => console.log(entry));
})
return val;
}
doSomething(4);

Visual Studio 2013 -- "Forcing recompile of all source files due to missing PDB". I turned on detailed build output to locate the issue: I enabled "Detailed" build output under "Tools" ? "Projects and Solutions" ? "Build and Run".
I had several projects, all C++, I set the option for under project settings: (C/C++ ? Debug Information Format) to Program Database (/Zi) for the problem project. However, this did not stop the problem for that project. The problem came from one of the other C++ projects in the solution.
I set all C++ projects to "Program Database (/Zi)". This fixed the problem.
Again, the project reporting the problem was not the problem project. Try setting all projects to "Program Database (/Zi)" to fix the problem.
If the endpoint really is a direct link to the .xls file, you can try the following code to handle downloading:
public static boolean download(final File output, final String source) {
try {
if (!output.createNewFile()) {
throw new RuntimeException("Could not create new file!");
}
URL url = new URL(source);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
// Comment in the code in the following line in case the endpoint redirects instead of it being a direct link
// connection.setInstanceFollowRedirects(true);
connection.setRequestProperty("AUTH-KEY-PROPERTY-NAME", "yourAuthKey");
final ReadableByteChannel rbc = Channels.newChannel(connection.getInputStream());
final FileOutputStream fos = new FileOutputStream(output);
fos.getChannel().transferFrom(rbc, 0, 1 << 24);
fos.close();
return true;
} catch (final Exception e) {
e.printStackTrace();
}
return false;
}
All you should need to do is set the proper name for the auth token and fill it in.
Example usage:
download(new File("C:\\output.xls"), "http://www.website.com/endpoint");
The C# foreach doesn't have a built in index. You'll need to add an integer outside the foreach loop and increment it each time.
int i = -1;
foreach (Widget w in widgets)
{
i++;
// do something
}
Alternatively, you could use a standard for loop as follows:
for (int i = 0; i < widgets.Length; i++)
{
w = widgets[i];
// do something
}
Don't know it this is your problem but it was mine.

On newer versions of yum, this information is stored in the "yumdb" when the package is installed. This is the only 100% accurate way to get the information, and you can use:
yumdb search from_repo repoid
(or repoquery and grep -- don't grep yum output). However the command "find-repos-of-install" was part of yum-utils for a while which did the best guess without that information:
http://james.fedorapeople.org/yum/commands/find-repos-of-install.py
As floyd said, a lot of repos. include a unique "dist" tag in their release, and you can look for that ... however from what you said, I guess that isn't the case for you?
from an activity you can do:
getWindow().setStatusBarColor(i color);
try this:
<input type="button" onClick="document.getElementById('middle').scrollIntoView();" />
Pete Goodliffe has a series on the unit testing of threaded code.
It's hard. I take the easier way out and try to keep the threading code abstracted from the actual test. Pete does mention that the way I do it is wrong but I've either got the separation right or I've just been lucky.
You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.
I think what you were looking for in your Range was this:
Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete
Just change the column letters to match your needs.
No need for an onchange function. You can grab the value in one line:
document.getElementById("select_id").options[document.getElementById("select_id").selectedIndex].value;
Or, split it up for better readability:
var select_id = document.getElementById("select_id");
select_id.options[select_id.selectedIndex].value;
Concepts
Observables in short tackles asynchronous processing and events. Comparing to promises this could be described as observables = promises + events.
What is great with observables is that they are lazy, they can be canceled and you can apply some operators in them (like map
, ...). This allows to handle asynchronous things in a very flexible way.
A great sample describing the best the power of observables is the way to connect a filter input to a corresponding filtered list. When the user enters characters, the list is refreshed. Observables handle corresponding AJAX requests and cancel previous in-progress requests if another one is triggered by new value in the input. Here is the corresponding code:
this.textValue.valueChanges
.debounceTime(500)
.switchMap(data => this.httpService.getListValues(data))
.subscribe(data => console.log('new list values', data));
(textValue
is the control associated with the filter input).
Here is a wider description of such use case: How to watch for form changes in Angular 2?.
There are two great presentations at AngularConnect 2015 and EggHead:
Christoph Burgdorf also wrote some great blog posts on the subject:
In action
In fact regarding your code, you mixed two approaches ;-) Here are they:
Manage the observable by your own. In this case, you're responsible to call the subscribe
method on the observable and assign the result into an attribute of the component. You can then use this attribute in the view for iterate over the collection:
@Component({
template: `
<h1>My Friends</h1>
<ul>
<li *ngFor="#frnd of result">
{{frnd.name}} is {{frnd.age}} years old.
</li>
</ul>
`,
directive:[CORE_DIRECTIVES]
})
export class FriendsList implement OnInit, OnDestroy {
result:Array<Object>;
constructor(http: Http) {
}
ngOnInit() {
this.friendsObservable = http.get('friends.json')
.map(response => response.json())
.subscribe(result => this.result = result);
}
ngOnDestroy() {
this.friendsObservable.dispose();
}
}
Returns from both get
and map
methods are the observable not the result (in the same way than with promises).
Let manage the observable by the Angular template. You can also leverage the async
pipe to implicitly manage the observable. In this case, there is no need to explicitly call the subscribe
method.
@Component({
template: `
<h1>My Friends</h1>
<ul>
<li *ngFor="#frnd of (result | async)">
{{frnd.name}} is {{frnd.age}} years old.
</li>
</ul>
`,
directive:[CORE_DIRECTIVES]
})
export class FriendsList implement OnInit {
result:Array<Object>;
constructor(http: Http) {
}
ngOnInit() {
this.result = http.get('friends.json')
.map(response => response.json());
}
}
You can notice that observables are lazy. So the corresponding HTTP request will be only called once a listener with attached on it using the subscribe
method.
You can also notice that the map
method is used to extract the JSON content from the response and use it then in the observable processing.
Hope this helps you, Thierry

I created simple examples to clarify understanding of ManualResetEvent
vs AutoResetEvent
.
AutoResetEvent
: lets assume you have 3 workers thread. If any of those threads will call WaitOne()
all other 2 threads will stop execution and wait for signal. I am assuming they are using WaitOne()
. It is like; if I do not work, nobody works. In first example you can see that
autoReset.Set();
Thread.Sleep(1000);
autoReset.Set();
When you call Set()
all threads will work and wait for signal. After 1 second I am sending second signal and they execute and wait (WaitOne()
). Think about these guys are soccer team players and if one player says I will wait until manager calls me, and others will wait until manager tells them to continue (Set()
)
public class AutoResetEventSample
{
private AutoResetEvent autoReset = new AutoResetEvent(false);
public void RunAll()
{
new Thread(Worker1).Start();
new Thread(Worker2).Start();
new Thread(Worker3).Start();
autoReset.Set();
Thread.Sleep(1000);
autoReset.Set();
Console.WriteLine("Main thread reached to end.");
}
public void Worker1()
{
Console.WriteLine("Entered in worker 1");
for (int i = 0; i < 5; i++) {
Console.WriteLine("Worker1 is running {0}", i);
Thread.Sleep(2000);
autoReset.WaitOne();
}
}
public void Worker2()
{
Console.WriteLine("Entered in worker 2");
for (int i = 0; i < 5; i++) {
Console.WriteLine("Worker2 is running {0}", i);
Thread.Sleep(2000);
autoReset.WaitOne();
}
}
public void Worker3()
{
Console.WriteLine("Entered in worker 3");
for (int i = 0; i < 5; i++) {
Console.WriteLine("Worker3 is running {0}", i);
Thread.Sleep(2000);
autoReset.WaitOne();
}
}
}
In this example you can clearly see that when you first hit Set()
it will let all threads go, then after 1 second it signals all threads to wait! As soon as you set them again regardless they are calling WaitOne()
inside, they will keep running because you have to manually call Reset()
to stop them all.
manualReset.Set();
Thread.Sleep(1000);
manualReset.Reset();
Console.WriteLine("Press to release all threads.");
Console.ReadLine();
manualReset.Set();
It is more about Referee/Players relationship there regardless of any of the player is injured and wait for playing others will continue to work. If Referee says wait (Reset()
) then all players will wait until next signal.
public class ManualResetEventSample
{
private ManualResetEvent manualReset = new ManualResetEvent(false);
public void RunAll()
{
new Thread(Worker1).Start();
new Thread(Worker2).Start();
new Thread(Worker3).Start();
manualReset.Set();
Thread.Sleep(1000);
manualReset.Reset();
Console.WriteLine("Press to release all threads.");
Console.ReadLine();
manualReset.Set();
Console.WriteLine("Main thread reached to end.");
}
public void Worker1()
{
Console.WriteLine("Entered in worker 1");
for (int i = 0; i < 5; i++) {
Console.WriteLine("Worker1 is running {0}", i);
Thread.Sleep(2000);
manualReset.WaitOne();
}
}
public void Worker2()
{
Console.WriteLine("Entered in worker 2");
for (int i = 0; i < 5; i++) {
Console.WriteLine("Worker2 is running {0}", i);
Thread.Sleep(2000);
manualReset.WaitOne();
}
}
public void Worker3()
{
Console.WriteLine("Entered in worker 3");
for (int i = 0; i < 5; i++) {
Console.WriteLine("Worker3 is running {0}", i);
Thread.Sleep(2000);
manualReset.WaitOne();
}
}
}
Use req.query, for getting he value in query string parameter in the route. Refer req.query. Say if in a route, http://localhost:3000/?name=satyam you want to get value for name parameter, then your 'Get' route handler will go like this :-
app.get('/', function(req, res){
console.log(req.query.name);
res.send('Response send to client::'+req.query.name);
});
declare class member
static int i = 0;
mNotificationManager.notify(++i, mBuilder.build());
Laravel min
and max
validation do not work properly with a numeric
rule validation. Instead of numeric, min and max
, Laravel provided a rule digits_between
.
$this->validate($request,[
'field_name'=>'digits_between:2,5',
]);
Though @chrisb's accepted answer does answer the question, I would like to add to it the following.
A simple method I use to get the nth
data or drop the nth
row is the following:
df1 = df[df.index % 3 != 0] # Excludes every 3rd row starting from 0
df2 = df[df.index % 3 == 0] # Selects every 3rd raw starting from 0
This arithmetic based sampling has the ability to enable even more complex row-selections.
This assumes, of course, that you have an index
column of ordered, consecutive, integers starting at 0.
You can use this:
const today = moment();
const tomorrow = moment().add(1, 'days');
const yesterday = moment().subtract(1, 'days');
The distinction between reference types and value types are basically a performance tradeoff in the design of the language. Reference types have some overhead on construction and destruction and garbage collection, because they are created on the heap. Value types on the other hand have overhead on method calls (if the data size is larger than a pointer), because the whole object is copied rather than just a pointer. Because strings can be (and typically are) much larger than the size of a pointer, they are designed as reference types. Also, as Servy pointed out, the size of a value type must be known at compile time, which is not always the case for strings.
The question of mutability is a separate issue. Both reference types and value types can be either mutable or immutable. Value types are typically immutable though, since the semantics for mutable value types can be confusing.
Reference types are generally mutable, but can be designed as immutable if it makes sense. Strings are defined as immutable because it makes certain optimizations possible. For example, if the same string literal occurs multiple times in the same program (which is quite common), the compiler can reuse the same object.
So why is "==" overloaded to compare strings by text? Because it is the most useful semantics. If two strings are equal by text, they may or may not be the same object reference due to the optimizations. So comparing references are pretty useless, while comparing text are almost always what you want.
Speaking more generally, Strings has what is termed value semantics. This is a more general concept than value types, which is a C# specific implementation detail. Value types have value semantics, but reference types may also have value semantics. When a type have value semantics, you can't really tell if the underlying implementation is a reference type or value type, so you can consider that an implementation detail.
You were right regarding how you want to generate salt i.e. its nothing but a random number. For this particular case it would protect your system from possible Dictionary attacks. Now, for the second problem what you could do is instead of using UTF-8 encoding you may want to use Base64. Here, is a sample for generating a hash. I am using Apache Common Codecs for doing the base64 encoding you may select one of your own
public byte[] generateSalt() {
SecureRandom random = new SecureRandom();
byte bytes[] = new byte[20];
random.nextBytes(bytes);
return bytes;
}
public String bytetoString(byte[] input) {
return org.apache.commons.codec.binary.Base64.encodeBase64String(input);
}
public byte[] getHashWithSalt(String input, HashingTechqniue technique, byte[] salt) throws NoSuchAlgorithmException {
MessageDigest digest = MessageDigest.getInstance(technique.value);
digest.reset();
digest.update(salt);
byte[] hashedBytes = digest.digest(stringToByte(input));
return hashedBytes;
}
public byte[] stringToByte(String input) {
if (Base64.isBase64(input)) {
return Base64.decodeBase64(input);
} else {
return Base64.encodeBase64(input.getBytes());
}
}
Here is some additional reference of the standard practice in password hashing directly from OWASP
I've used OpenCSV in the past.
import au.com.bytecode.opencsv.CSVReader;
String fileName = "data.csv"; CSVReader reader = new CSVReader(new FileReader(fileName ));// if the first line is the header String[] header = reader.readNext();
// iterate over reader.readNext until it returns null String[] line = reader.readNext();
There were some other choices in the answers to another question.

Update! Scroll to bottom of answer for
smartSort
prop additive that gives even more fun!
Sorts arrays of anything!
My personal favorite form of this function allows for a param for Ascending, or Descending:
function intArraySort(c, a) {
function d(a, b) { return b - a; }
"string" == typeof a && a.toLowerCase();
switch (a) {
default: return c.sort(function(a, b) { return a - b; });
case 1:
case "d":
case "dc":
case "desc":
return c.sort(d)
}
};
Usage as simple as:
var ara = function getArray() {
var a = Math.floor(Math.random()*50)+1, b = [];
for (i=0;i<=a;i++) b.push(Math.floor(Math.random()*50)+1);
return b;
}();
// Ascending
intArraySort(ara);
console.log(ara);
// Descending
intArraySort(ara, 1);
console.log(ara);
// Ascending
intArraySort(ara, 'a');
console.log(ara);
// Descending
intArraySort(ara, 'dc');
console.log(ara);
// Ascending
intArraySort(ara, 'asc');
console.log(ara);

Now have even more fun with a sorting method that sorts an array full of multiple items! Doesn't currently cover "associative" (aka, string keys), but it does cover about every type of value! Not only will it sort the multiple values asc
or desc
accordingly, but it will also maintain constant "position" of "groups" of values. In other words; ints are always first, then come strings, then arrays (yes, i'm making this multidimensional!), then Objects (unfiltered, element, date), & finally undefineds and nulls!
"Why?" you ask. Why not!
Now comes in 2 flavors! The first of which requires newer browsers as it uses Object.defineProperty
to add the method to the Array.protoype
Object. This allows for ease of natural use, such as: myArray.smartSort('a')
. If you need to implement for older browsers, or you simply don't like modifying native Objects, scroll down to Method Only version.

jsFiddle Array.prototype.smartSort('asc|desc')
Use is simple! First make some crazy array like:
window.z = [ 'one', undefined, $('<span />'), 'two', null, 2, $('<div />', { id: 'Thing' }), $('<div />'), 4, $('<header />') ];
z.push(new Date('1/01/2011'));
z.push('three');
z.push(undefined);
z.push([ 'one', 'three', 'four' ]);
z.push([ 'one', 'three', 'five' ]);
z.push({ a: 'a', b: 'b' });
z.push({ name: 'bob', value: 'bill' });
z.push(new Date());
z.push({ john: 'jill', jack: 'june' });
z.push([ 'abc', 'def', [ 'abc', 'def', 'cba' ], [ 'cba', 'def', 'bca' ], 'cba' ]);
z.push([ 'cba', 'def', 'bca' ]);
z.push({ a: 'a', b: 'b', c: 'c' });
z.push({ a: 'a', b: 'b', c: 'd' });
Then simply sort it!
z.smartSort('asc'); // Ascending
z.smartSort('desc'); // Descending
Same as the preceding, except as just a simple method!

As of Json.NET 4.0 Release 1, there is native dynamic support.
You don't need to declare a class, just use dynamic
:
dynamic jsonDe = JsonConvert.DeserializeObject(json);
All the fields will be available:
foreach (string typeStr in jsonDe.Type[0])
{
// Do something with typeStr
}
string t = jsonDe.t;
bool a = jsonDe.a;
object[] data = jsonDe.data;
string[][] type = jsonDe.Type;
With dynamic you don't need to create a specific class to hold your data.
If you are using HTML5, using the Video tag is suitable for this purpose.
You can use the Video Tag this way for no autoplay:
<video width="320" height="240" controls>
<source src="videos/example.mp4" type="video/mp4">
</video>
To enable auto-play,
<video width="320" height="240" controls autoplay>
<source src="videos/example.mp4" type="video/mp4">
</video>
I think an option for your purposes is git log --online --decorate
. This lets you know the checked commit, and the top commits for each branch that you have in your story line. By doing this, you have a nice view on the structure of your repo and the commits associated to a specific branch. I think reading this might help.
This just happened to me.
Solution: Pull down my own branch so I get that extra commit. Then push it back to my remote branch.
literally what I did on my branch was:
git pull
git push
Did you try with strip() :
listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric']
print [item.strip('0') for item in listOfNum]
>>> ['231512-n', '1209123100000-n', 'alphanumeric', 'alphanumeric']
After a lot of looking at ways to perform this I ended up using jq
, and hopefully I can expand it to handle other repos beyond Docker-Compose without too much work.
# If you have jq installed this will automatically find the latest release binary for your architecture and download it

Here's yet another answer offering commentary on how Muis, Abdullah Al-Ageel and Flip's answer are all mathematically the same thing except written differently.
Sure, we have José Manuel Ramos's analysis explaining how rounding errors affect each slightly differently, but that's implementation dependent and would change based on how each answer were applied to code.
It's in Muis's N
, Flip's k
, and Abdullah Al-Ageel's n
. Abdullah Al-Ageel doesn't quite explain what n
should be, but N
and k
differ in that N
is "the number of samples where you want to average over" while k
is the count of values sampled. (Although I have doubts to whether calling N
the number of samples is accurate.)
And here we come to the answer below. It's essentially the same old exponential weighted moving average as the others, so if you were looking for an alternative, stop right here.
Initially:
average = 0
counter = 0
For each value:
counter += 1
average = average + (value - average) / min(counter, FACTOR)
The difference is the min(counter, FACTOR)
part. This is the same as saying min(Flip's k, Muis's N)
.
FACTOR
is a constant that affects how quickly the average "catches up" to the latest trend. Smaller the number the faster. (At 1
it's no longer an average and just becomes the latest value.)
This answer requires the running counter counter
. If problematic, the min(counter, FACTOR)
can be replaced with just FACTOR
, turning it into Muis's answer. The problem with doing this is the moving average is affected by whatever average
is initiallized to. If it was initialized to 0
, that zero can take a long time to work its way out of the average.
Yes, you can use the *args
(splat) syntax:
function_that_needs_strings(*my_list)
where my_list
can be any iterable; Python will loop over the given object and use each element as a separate argument to the function.
See the call expression documentation.
There is a keyword-parameter equivalent as well, using two stars:
kwargs = {'foo': 'bar', 'spam': 'ham'}
f(**kwargs)
and there is equivalent syntax for specifying catch-all arguments in a function signature:
def func(*args, **kw):
# args now holds positional arguments, kw keyword arguments
Use a fully-qualified path to the desktop (e.g., /home/mmurphy/Desktop
).
Example: adb pull sdcard/log.txt /home/mmurphy/Desktop
PixlUI project allows you to use textAllCaps in any textview or subclass of textview including: Button, EditText AutoCompleteEditText Checkbox RadioButton and several others.
You will need to create your textviews using the pixlui version rather than the ones from the android source, meaning you have to do this:
<com.neopixl.pixlui.components.textview.TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world"
pixlui:textAllCaps="true" />
PixlUI also allows you to set a custom typeface/font which you put in your assets folder.
I'm working on a Gradle fork of the PixlUI framework which uses gradle and allows one to specify textAllCaps as well as the typeface from styles rather than requiring them inline as the original project does.
You should be able to download the file using
window.open("data:application/pdf;base64," + Base64.encode(out));
Another way (currently showing 25MB free on my G1):
MemoryInfo mi = new MemoryInfo();
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
activityManager.getMemoryInfo(mi);
long availableMegs = mi.availMem / 1048576L;
Static memory allocation. Memory allocated will be in stack.
int a[10];
Dynamic memory allocation. Memory allocated will be in heap.
int *a = malloc(sizeof(int) * 10);
and the latter should be freed since there is no Garbage Collector(GC) in C.
free(a);
Is of course a Bug.
Probably somewhere in your code you use table.estimatedRowHeight = value
(for example 100). Replace this value by the highest value you think a row height could get, for example 500..
This should solve the problem in combination with following code:
//auto scroll down example
let delay = 0.1 * Double(NSEC_PER_SEC)
let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
dispatch_after(time, dispatch_get_main_queue(), {
self.table.scrollToRowAtIndexPath(NSIndexPath(forRow: self.Messages.count - 1, inSection: 0), atScrollPosition: UITableViewScrollPosition.Bottom, animated: false)
})
I had a similar problem when I used one library in several applications. It was necessary just update your AndroidManifest.xml with this exact provider declaration below.
<manifest ...>
<application ...>
<provider android:name="android.support.v4.content.FileProvider" android:authorities="${applicationId}.here.this.library.provider" android:exported="false" android:grantUriPermissions="true" tools:replace="android:authorities">
</provider>
</application>
</manifest>
My solution is a little hood but it works. What I do is just basically detect where the number is going to be and use css
to have a box cover over it. I guess you can also cheat the system and add more hits if you want. Here is my code using jquery
but it will be different than others depending on where you place the like button on your page.
Not the most glamorous but hey the security is to tight to manipulate content in side of a frame.
<script type="text/javascript">
var facebook_load = '';
$(document).ready(function() {
facebook_load = setInterval('checkIframeFacebookLoad()',100);
});
function checkIframeFacebookLoad() {
if($('iframe.fb_ltr').length) {
var parent = $('iframe.fb_ltr').parent();
var hide_counter = $('<div></div>').attr('id', 'hide_count');
parent.append(hide_counter);
clearInterval(facebook_load);
}
}
</script>
<style type="text/css">
#hide_count {
position:absolute;
top:-8px;
left:122px;
background:#becdd5;
padding:5px 10px;
}
</style>
I'll add XMLSerializer
to the pile. It provides the fastest result without using any object caching (not on the serializer, nor on the Text node).
function serializeTextNode(text) {
return new XMLSerializer().serializeToString(document.createTextNode(text));
}
The added bonus is that it supports attributes which is serialized differently than text nodes:
function serializeAttributeValue(value) {
const attr = document.createAttribute('a');
attr.value = value;
return new XMLSerializer().serializeToString(attr);
}
You can see what it's actually replacing by checking the spec, both for text nodes and for attribute values. The full documentation has more node types, but the concept is the same.
As for performance, it's the fastest when not cached. When you do allow caching, then calling innerHTML
on an HTMLElement with a child Text node is fastest. Regex would be slowest (as proven by other comments). Of course, XMLSerializer could be faster on other browsers, but in my (limited) testing, a innerHTML
is fastest.
Fastest single line:
new XMLSerializer().serializeToString(document.createTextNode(text));
Fastest with caching:
const cachedElementParent = document.createElement('div');
const cachedChildTextNode = document.createTextNode('');
cachedElementParent.appendChild(cachedChildTextNode);
function serializeTextNode(text) {
cachedChildTextNode.nodeValue = text;
return cachedElementParent.innerHTML;
}
Also worth mentioning, in C# the OR operator is short-circuiting. In your example, Close seems to be a property, but if it were a method, it's worth noting that:
if (ActionsLogWriter.Close() || ErrorDumpWriter.Close())
is fundamentally different from
if (ErrorDumpWriter.Close() || ActionsLogWriter.Close())
In C#, if the first expression returns true, the second expression will not be evaluated at all. Just be aware of this. It actually works to your advantage most of the time.
Quick and dirt alternative solution. You can use a tabulation character along with preformatted text. Here's a possibility:
<style type="text/css">
ol {
list-style-position: inside;
}
li:first-letter {
white-space: pre;
}
</style>
and your html:
<ol>
<li> an item</li>
<li> another item</li>
...
</ol>
Note that the space between the li
tag and the beggining of the text is a tabulation character (what you get when you press the tab key inside notepad).
If you need to support older browsers, you can do this instead:
<style type="text/css">
ol {
list-style-position: inside;
}
</style>
<ol>
<li><pre> </pre>an item</li>
<li><pre> </pre>another item</li>
...
</ol>
You may not have permission to dba_sequences. So you can always just do:
select * from user_sequences;
Use:
SELECT DATE_FORMAT(NAME_COLUMN, "%d/%l/%Y") AS 'NAME'
SELECT DATE_FORMAT(NAME_COLUMN, "%d/%l/%Y %H:%i:%s") AS 'NAME'

You could use Role Strategy plugin for that purpose. It works like a charm, just setup some roles and assign them. Even on project-specific level.
I had the same error. I know this thread is pretty much dead already but I want to set another option besides "anonymous procedure".
I solved it like this:
Check if the stored procedure exist:
IF NOT EXISTS (SELECT * FROM sysobjects WHERE name='my_procedure') BEGIN
print 'exists' -- or watever you want
END ELSE BEGIN
print 'doesn''texists' -- or watever you want
END
However the "CREATE/ALTER PROCEDURE' must be the first statement in a query batch"
is still there. I solved it like this:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE -- view procedure function or anything you want ...
I end up with this code:
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID('my_procedure'))
BEGIN
DROP PROCEDURE my_procedure
END
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].my_procedure ...
Check the manual for mysql_fetch_object()
. It returns an object, not an array of objects.
I'm guessing you want something like this
$results = mysql_query("SELECT * FROM sidemenu WHERE `menu_id`='".$menu."' ORDER BY `id` ASC LIMIT 1", $con);
$sidemenus = array();
while ($sidemenu = mysql_fetch_object($results)) {
$sidemenus[] = $sidemenu;
}
Might I suggest you have a look at PDO. PDOStatement::fetchAll(PDO::FETCH_OBJ)
does what you assumed mysql_fetch_object()
to do
In script is usefull something like this:

If you don't have a version of date that supports --yesterday and you don't want to use perl, you can use this handy ksh script of mine. By default, it returns yesterday's date, but you can feed it a number and it tells you the date that many days in the past. It starts to slow down a bit if you're looking far in the past. 100,000 days ago it was 1/30/1738, though my system took 28 seconds to figure that out.

Random AirCoded example of testing "set equality" in jQuery:
$.fn.isEqual = function($otherSet) {
if (this === $otherSet) return true;
if (this.length != $otherSet.length) return false;
var ret = true;
this.each(function(idx) {
if (this !== $otherSet[idx]) {
ret = false; return false;
}
});
return ret;
};
var a=$('#start > div:last-child');
var b=$('#start > div.live')[0];
console.log($(b).isEqual(a));
A file object is an instance of Blob but a blob object is not an instance of File
new File([], 'foo.txt').constructor.name === 'File' //true
new File([], 'foo.txt') instanceof File // true
new File([], 'foo.txt') instanceof Blob // true
new Blob([]).constructor.name === 'Blob' //true
new Blob([]) instanceof Blob //true
new Blob([]) instanceof File // false
new File([], 'foo.txt').constructor.name === new Blob([]).constructor.name //false
If you must convert a file object to a blob object, you can create a new Blob object using the array buffer of the file. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
let reader = new FileReader();
reader.onload = function(e) {
let blob = new Blob([new Uint8Array(e.target.result)], {type: file.type });
console.log(blob);
};
reader.readAsArrayBuffer(file);
As pointed by @bgh you can also use the arrayBuffer method of the File object. See the example below.
let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
file.arrayBuffer().then((arrayBuffer) => {
let blob = new Blob([new Uint8Array(arrayBuffer)], {type: file.type });
console.log(blob);
});
If your environment supports async/await you can use a one-liner like below
let fileToBlob = async (file) => new Blob([new Uint8Array(await file.arrayBuffer())], {type: file.type });
console.log(await fileToBlob(new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'})));
Actually the only two strategies you would want to choose are ours if you want to abandon changes brought by branch, but keep the branch in history, and subtree if you are merging independent project into subdirectory of superproject (like 'git-gui' in 'git' repository).
octopus merge is used automatically when merging more than two branches. resolve is here mainly for historical reasons, and for when you are hit by recursive merge strategy corner cases.
In my case, the only option was to remove the VM and download it again. No re-configuration of the host-only adapter did not help, I used different addressing of DHCP. Virtual Box I updated to version 4.3.4 and Genymotion to 2.0.2
Could use CASE WHEN

Scope means the code context that performs the INSERT
statement SCOPE_IDENTITY()
, as opposed to the global scope of @@IDENTITY
.
CREATE TABLE Foo(
ID INT IDENTITY(1,1),
Dummy VARCHAR(100)
)
CREATE TABLE FooLog(
ID INT IDENTITY(2,2),
LogText VARCHAR(100)
)
go
CREATE TRIGGER InsertFoo ON Foo AFTER INSERT AS
BEGIN
INSERT INTO FooLog (LogText) VALUES ('inserted Foo')
INSERT INTO FooLog (LogText) SELECT Dummy FROM inserted
END
INSERT INTO Foo (Dummy) VALUES ('x')
SELECT SCOPE_IDENTITY(), @@IDENTITY
Gives different results.
var text ="";
for (var member in list) {
text += list[member];
}
You can also use the java.time package in Java 8 and convert your java.util.Date
object to a java.time.LocalDate
object and then just use the getMonthValue()
method.
Date date = new Date();
LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
int month = localDate.getMonthValue();
Note that month values are here given from 1 to 12 contrary to cal.get(Calendar.MONTH)
in adarshr's answer which gives values from 0 to 11.
But as Basil Bourque said in the comments, the preferred way is to get a Month
enum object with the LocalDate::getMonth
method.
ng-bind
is better than {{...}}
For example, you could do:
<div>
Hello, {{variable}}
</div>
This means that the whole text Hello, {{variable}}
enclosed by <div>
will be copied and stored in memory.
If instead you do something like this:
<div>
Hello, <span ng-bind="variable"></span>
</div>
Only the value of the value will be stored in memory, and angular will register a watcher (watch expression) which consists of the variable only.
Here is one way to test which YAML implementation the user has selected on the virtualenv (or the system) and then define load_yaml_file
appropriately:
load_yaml_file = None
if not load_yaml_file:
try:

load_yaml_file = lambda fn: yaml.load(open(fn))
except:
pass
if not load_yaml_file:
import commands, json
if commands.getstatusoutput('ruby --version')[0] == 0:
def load_yaml_file(fn):
ruby = "puts YAML.load_file('%s').to_json" % fn
j = commands.getstatusoutput('ruby -ryaml -rjson -e "%s"' % ruby)
return json.loads(j[1])
if not load_yaml_file:
import os, sys
print """

I took the liberty to expand the answer from nona-urbiz; just add this to your ~/.bashrc:
git-pullall () { for RMT in $(git remote); do git pull -v $RMT $1; done; }
alias git-pullall=git-pullall
git-pushall () { for RMT in $(git remote); do git push -v $RMT $1; done; }
alias git-pushall=git-pushall
Usage:
git-pullall master
git-pushall master ## or
git-pushall
If you do not provide any branch argument for git-pullall then the pull from non-default remotes will fail; left this behavior as it is, since it's analogous to git.
Use ioutil.ReadFile
:
func ReadFile(filename string) ([]byte, error)
ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported.
You will get a []byte
instead of a string
. It can be converted if really necessary:
s := string(buf)
<a href="#"><i class="fab fa-facebook-square"></i></a>
<a href="#"><i class="fab fa-twitter-square"></i></a>
<a href="#"><i class="fas fa-basketball-ball"></i></a>
<a href="#"><i class="fab fa-google-plus-square"></i></a>
All you have to do is wrap your font-awesome icon link in your HTML
with an anchor tag.
Following this format:
<a href="Link here"> <font-awesome icon code> </a>
Try this ( also corrected check for upper case and lower case, it had a bug since you grouped them as [a-zA-Z] it only looks for atleast one lower or upper. So separated them out ):
(?!^[0-9]*$)(?!^[a-z]*$)(?!^[A-Z]*$)^(.{8,15})$
Update: I found that the regex doesn't really work as expected and this is not how it is supposed to be written too!
Try something like this:
(?=^.{8,15}$)(?=.*\d)(?=.*[A-Z])(?=.*[a-z])(?!.*\s).*$
(Between 8 and 15 inclusive, contains atleast one digit, atleast one upper case and atleast one lower case and no whitespace.)
And I think this is easier to understand as well.
All answers are great. Here is an example use case for multiple add address: The ability to add as many email you want on demand with a web form:
See it in action with jsfiddle here (except the php processor)
### Send unlimited email with a web form
# Form for continuously adding e-mails:
<button type="button" onclick="emailNext();">Click to Add Another Email.</button>
<div id="addEmail"></div>
<button type="submit">Send All Emails</button>
# Script function:
<script>
function emailNext() {
var nextEmail, inside_where;
nextEmail = document.createElement('input');
nextEmail.type = 'text';
nextEmail.name = 'emails[]';
nextEmail.className = 'class_for_styling';
nextEmail.style.display = 'block';
nextEmail.placeholder = 'Enter E-mail Here';
inside_where = document.getElementById('addEmail');
inside_where.appendChild(nextEmail);
return false;
}
</script>
# PHP Data Processor:
<?php
// ...
// Add the rest of your $mailer here...
if ($_POST[emails]){
foreach ($_POST[emails] AS $postEmail){
if ($postEmail){$mailer->AddAddress($postEmail);}
}
}
?>
So what it does basically is to generate a new input text box on every click with the name "emails[]".
The [] added at the end makes it an array when posted.
Then we go through each element of the array with "foreach" on PHP side adding the:
$mailer->AddAddress($postEmail);
This should do it:
[entry for tag in tags for entry in entries if tag in entry]
This solution worked for me:
Started working after adding property:
mail.smtp.starttls.enable=true
Using:
mail.smtp.host=smtp.office365.com
mail.smtp.port=587
mail.transport.protocol=smtp
mail.smtp.auth=true
mail.smtp.starttls.enable=true
[email protected]
mail.smtp.password=xxx
[email protected]
I think the client looks like a normal asynchronous AJAX request, but you expect it to take a "long time" to come back.
The server then looks like this.
while (!hasNewData())
usleep(50);
outputNewData();
So, the AJAX request goes to the server, probably including a timestamp of when it was last update so that your hasNewData()
knows what data you have already got.
The server then sits in a loop sleeping until new data is available. All the while, your AJAX request is still connected, just hanging there waiting for data.
Finally, when new data is available, the server gives it to your AJAX request and closes the connection.
If you want to throw an exception from the catch block you must inform your method/class/etc. that it needs to throw said exception. Like so:
public void doStuff() throws MyException {
try {
//Stuff
} catch(StuffException e) {
throw new MyException();
}
}
And now your compiler will not yell at you :)
Place single quotes around the Extended Properties

Try it, it really works.

In my case adding multiDexEnabled true in Android/build/build.gradle file compiled the files.

You have to invoke this class on the top of your page or class :

This is a good and a tricky question. The topic of URI design is at the same time the most prominent part of a REST API and, therefore, a potentially long-term commitment towards the users of that API.
Since evolution of an application and, to a lesser extent, its API is a fact of life and that it's even similar to the evolution of a seemingly complex product like a programming language, the URI design should have less natural constraints and it should be preserved over time. The longer the application's and API's lifespan, the greater the commitment to the users of the application and API.
On the other hand, another fact of life is that it is hard to foresee all the resources and their aspects that would be consumed through the API. Luckily, it is not necessary to design the entire API which will be used until Apocalypse. It is sufficient to correctly define all the resource end-points and the addressing scheme of every resource and resource instance.
Over time you may need to add new resources and new attributes to each particular resource, but the method that API users follow to access a particular resources should not change once a resource addressing scheme becomes public and therefore final.
This method applies to HTTP verb semantics (e.g. PUT should always update/replace) and HTTP status codes that are supported in earlier API versions (they should continue to work so that API clients that have worked without human intervention should be able to continue to work like that).
Furthermore, since embedding of API version into the URI would disrupt the concept of hypermedia as the engine of application state (stated in Roy T. Fieldings PhD dissertation) by having a resource address/URI that would change over time, I would conclude that API versions should not be kept in resource URIs for a long time meaning that resource URIs that API users can depend on should be permalinks.
Sure, it is possible to embed API version in base URI but only for reasonable and restricted uses like debugging a API client that works with the the new API version. Such versioned APIs should be time-limited and available to limited groups of API users (like during closed betas) only. Otherwise, you commit yourself where you shouldn't.
A couple of thoughts regarding maintenance of API versions that have expiration date on them. All programming platforms/languages commonly used to implement web services (Java, .NET, PHP, Perl, Rails, etc.) allow easy binding of web service end-point(s) to a base URI. This way it's easy to gather and keep a collection of files/classes/methods separate across different API versions.
From the API users POV, it's also easier to work with and bind to a particular API version when it's this obvious but only for limited time, i.e. during development.
From the API maintainer's POV, it's easier to maintain different API versions in parallel by using source control systems that predominantly work on files as the smallest unit of (source code) versioning.
However, with API versions clearly visible in URI there's a caveat: one might also object this approach since API history becomes visible/aparent in the URI design and therefore is prone to changes over time which goes against the guidelines of REST. I agree!
The way to go around this reasonable objection, is to implement the latest API version under versionless API base URI. In this case, API client developers can choose to either:
develop against the latest one (committing themselves to maintain the application protecting it from eventual API changes that might break their badly designed API client).
bind to a specific version of the API (which becomes apparent) but only for a limited time
For example, if API v3.0 is the latest API version, the following two should be aliases (i.e. behave identically to all API requests):
http://shonzilla/api/customers/1234 http://shonzilla/api/v3.0/customers/1234 http://shonzilla/api/v3/customers/1234
In addition, API clients that still try to point to the old API should be informed to use the latest previous API version, if the API version they're using is obsolete or not supported anymore. So accessing any of the obsolete URIs like these:
http://shonzilla/api/v2.2/customers/1234 http://shonzilla/api/v2.0/customers/1234 http://shonzilla/api/v2/customers/1234 http://shonzilla/api/v1.1/customers/1234 http://shonzilla/api/v1/customers/1234
should return any of the 30x HTTP status codes that indicate redirection that are used in conjunction with Location
HTTP header that redirects to the appropriate version of resource URI which remain to be this one:
http://shonzilla/api/customers/1234
There are at least two redirection HTTP status codes that are appropriate for API versioning scenarios:
301 Moved permanently indicating that the resource with a requested URI is moved permanently to another URI (which should be a resource instance permalink that does not contain API version info). This status code can be used to indicate an obsolete/unsupported API version, informing API client that a versioned resource URI been replaced by a resource permalink.
302 Found indicating that the requested resource temporarily is located at another location, while requested URI may still supported. This status code may be useful when the version-less URIs are temporarily unavailable and that a request should be repeated using the redirection address (e.g. pointing to the URI with APi version embedded) and we want to tell clients to keep using it (i.e. the permalinks).
other scenarios can be found in Redirection 3xx chapter of HTTP 1.1 specification

The solution to the problem for me was looking in my install directory, finding the /data folder, and copying it's content to the data folder that was specified in my .ini/.cnf configuration file.
Notice that for the general purpose use, this behavior is likely to be acceptable.
The problem arises when comparing those floating points values to determine an appropriate action.
With the advent of ES6, a new constant Number.EPSILON
is defined to determine the acceptable error margin :
So instead of performing the comparison like this
0.1 + 0.2 === 0.3 // which returns false
you can define a custom compare function, like this :
function epsEqu(x, y) {
return Math.abs(x - y) < Number.EPSILON;
}
console.log(epsEqu(0.1+0.2, 0.3)); // true

Well, it's unfortunate that you didn't post your own code too, so that it could be corrected.
Anyway, here's my own solution to this:
@echo off
setlocal enabledelayedexpansion
set OUTPUT_FILE=result.txt
>nul copy nul %OUTPUT_FILE%
for /f %%i in (testservers.txt) do (
set SERVER_ADDRESS=ADDRESS N/A
for /f "tokens=1,2,3" %%x in ('ping -n 1 %%i ^&^& echo SERVER_IS_UP') do (
if %%x==Pinging set SERVER_ADDRESS=%%y
if %%x==Reply set SERVER_ADDRESS=%%z
if %%x==SERVER_IS_UP (set SERVER_STATE=UP) else (set SERVER_STATE=DOWN)
)
echo %%i [!SERVER_ADDRESS::=!] is !SERVER_STATE! >>%OUTPUT_FILE%
)
The outer loop iterates through the hosts and the inner loop parses the ping
output. The first two if
statements handle the two possible cases of IP address resolution:
If the host IP address cannot be resolved, the address is set to "ADDRESS N/A".
Hope this helps.
datetime.datetime.fromtimestamp()
is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp()
expects Unix timestamp, in seconds.
Do it like that:
>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)
and the result is:
>>> date
datetime.datetime(2012, 3, 16, 1, 0)
Does it answer your question?
EDIT: J.F. Sebastian correctly suggested to use true division by 1e3
(float 1000
). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int
when dividing (using /
operator) int
by int
(this is called floor division). By replacing the divisor 1000
(being an int
) with the 1e3
divisor (being representation of 1000
as float) or with float(1000)
(or 1000.
etc.), the division becomes true division. Python 2.x returns float
when dividing int
by float
, float
by int
, float
by float
etc. And when there is some fractional part in the timestamp passed to fromtimestamp()
method, this method's result also contains information about that fractional part (as the number of microseconds).

In Order to implement Line Break in SSRS, there are 2 ways
<br/>
tag to introduce line break within the expression ="first line of text. Param1 value: " & Parameters!Param1.Value & "<br/>" & Parameters!Param1.Value
="first line of text. Param1 value: " & Parameters!Param1.Value & Environment.NewLine()
& Parameters!Param1.Value
Note:- Always remember to leave a space after every "&" (ampersand) in order to evaluate the expression properly

SELECT *
FROM myTable
WHERE URL = LEFT('mysyte.com/?id=2®ion=0&page=1', LEN(URL))
Or use CHARINDEX http://msdn.microsoft.com/en-us/library/aa258228(v=SQL.80).aspx
The datatype in the same columns name must be equals.
dataTable1.Merge(dataTable2);
After that the result is:
dataTable1 = dataTable1 + dataTable2
In numpy
, index and dimension numbering starts with 0. So axis 0
means the 1st dimension. Also in numpy
a dimension can have length (size) 0. The simplest case is:
In [435]: x = np.zeros((0,), int)
In [436]: x
Out[436]: array([], dtype=int32)
In [437]: x[0]
...
IndexError: index 0 is out of bounds for axis 0 with size 0
I also get it if x = np.zeros((0,5), int)
, a 2d array with 0 rows, and 5 columns.
So someplace in your code you are creating an array with a size 0 first axis.
When asking about errors, it is expected that you tell us where the error occurs.
Also when debugging problems like this, the first thing you should do is print the shape
(and maybe the dtype
) of the suspected variables.

The problem I need to solve is to store contracts containing a few fields (address, book, num_of_days, borrower_addr, blk_data), blk_data is a transaction list (block number and transaction address). This question and answer helped me. I would like to share my code as below. Hope this helps.
- Schema definition. See blk_data.
var ContractSchema = new Schema(
{
address: {type: String, required: true, max: 100}, //contract address
// book_id: {type: String, required: true, max: 100}, //book id in the book collection
book: { type: Schema.ObjectId, ref: 'clc_books', required: true }, // Reference to the associated book.
num_of_days: {type: Number, required: true, min: 1},
borrower_addr: {type: String, required: true, max: 100},
// status: {type: String, enum: ['available', 'Created', 'Locked', 'Inactive'], default:'Created'},
blk_data: [{
tx_addr: {type: String, max: 100}, // to do: change to a list
block_number: {type: String, max: 100}, // to do: change to a list
}]
}
);
- Create a record for the collection in the MongoDB. See blk_data.
// Post submit a smart contract proposal to borrowing a specific book.

var contract = new Contract(
{

On most systems, you'd have to be trying fairly hard not to find '<stdio.h>
', to the point where the first reaction is "is <stdio.h>
installed". So, I'd be looking to see if the file exists in a plausible location. If not, then your installation of Turbo C is broken; reinstall. If you can find it, then you will have to establish why the compiler is not searching for it in the right place - what are the compiler options you've specified and where is the compiler searching for its headers (and why isn't it searching where the header is).
1.Find that particular commit to which you want to revert using:
git log
This command will give you a list of commits done by you .
2.Revert to that commit using :
git revert <commit id>
Now you local branch would have all files in particular
If you need one single regex, try:
(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)
A short explanation:
(?=.*[a-z]) // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z]) // use positive look ahead to see if at least one upper case letter exists
(?=.*\d) // use positive look ahead to see if at least one digit exists
(?=.*\W]) // use positive look ahead to see if at least one non-word character exists
And I agree with SilentGhost, \W
might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?]

This could also happen if you don't add $('#myTable').DataTable();
inside the document.ready
So instead of this
$('#myTable').DataTable();
Try This
$(document).ready(function() {
$('#myTable').DataTable();
});

To understand how to use sqlite database in android with best practices see - Android with sqlite database
There are few classes about which you should know and those will help you model your tables and models i.e android.provider.BaseColumns
Below is an example of a table
public class ProductTable implements BaseColumns {
public static final String NAME = "name";
public static final String PRICE = "price";
public static final String TABLE_NAME = "products";
public static final String CREATE_QUERY = "create table " + TABLE_NAME + " (" +
_ID + " INTEGER, " +
NAME + " TEXT, " +
PRICE + " INTEGER)";
public static final String DROP_QUERY = "drop table " + TABLE_NAME;
public static final String SElECT_QUERY = "select * from " + TABLE_NAME;
