pluck(column_name)
This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.
Examples:
Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)
see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck
Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns
See https://docs.djangoproject.com/en/stable/ref/templates/builtins/#if : just use, to reproduce their example:
{% if athlete_list %}
Number of athletes: {{ athlete_list|length }}
{% else %}
No athletes.
{% endif %}

For those that are on Mac OSX, perhaps the easiest way to work around this is to use ditto (only on the mac, AFAIK, though). It will create the directory structure that is missing in the destination.
For instance, I did this
ditto 6.3.2/6.3.2/macosx/bin/mybinary ~/work/binaries/macosx/6.3.2/
where ~/work
did not contain the binaries directory before I ran the command.
I thought rsync should work similarly, but it seems it only works for one level of missing directories. That is,
rsync 6.3.3/6.3.3/macosx/bin/mybinary ~/work/binaries/macosx/6.3.3/
worked, because ~/work/binaries/macosx existed but not ~/work/binaries/macosx/6.3.2/
Solution described here helped me (webarchive link).
First of all, you can add border to all elements to see what causes a new page to be appended (maybe some margins, paddings, etc).
div { border: 1px solid black;}
And the solution itself was to add the following styles:
html, body { height: auto; }
If you need autocomplete support from within in your templates from the Angular Language Service:
Synchronous:
myVar = { hello: '' };
<ng-container *ngIf="myVar; let var;">
{{var.hello}}
</ng-container>
Using async pipe:
myVar$ = of({ hello: '' });
<ng-container *ngIf="myVar$ | async; let var;">
{{var.hello}}
</ng-container>
Inspired by Steve answer, I wrote simple function that toggles between vertical and horizontal splits for all windows in current tab. You can bind it to mapping like in the last line below.
function! ToggleWindowHorizontalVerticalSplit()
if !exists('t:splitType')
let t:splitType = 'vertical'
endif
if t:splitType == 'vertical' " is vertical switch to horizontal
windo wincmd K
let t:splitType = 'horizontal'
else " is horizontal switch to vertical
windo wincmd H
let t:splitType = 'vertical'
endif
endfunction
nnoremap <silent> <leader>wt :call ToggleWindowHorizontalVerticalSplit()<cr>
Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).
It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).
But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.
A good example: here
And a good documentation from Mozilla: here

If you have a class Car
public class Car {
private Color externalColor;
}
And the property Color is a class
@Data
public class Color {
private Integer id;
private String name;
}
And you want to convert Color to an Enum
public class CarDTO {
private ColorEnum externalColor;
}
Simply add a method in Color class to convert Color in ColorEnum
@Data
public class Color {
private Integer id;
private String name;
public ColorEnum getEnum(){
ColorEnum.getById(id);
}
}
and inside ColorEnum implements the method getById()
public enum ColorEnum {
...
public static ColorEnum getById(int id) {
for(ColorEnum e : values()) {
if(e.id==id)
return e;
}
}
}
Now you can use a classMap
private MapperFactory factory = new DefaultMapperFactory.Builder().build();
...
factory.classMap(Car.class, CarDTO.class)
.fieldAToB("externalColor.enum","externalColor")
.byDefault()
.register();
...
CarDTO dto = mapper.map(car, CarDTO.class);

NetBeans 7 has nice support for HTML5. Previously I was a heavy user of Eclipse, but spend more time with NetBeans to play with HTML5 and Servlet.
If you have a datatype which is bigger than the one you want to test (say you do a 32-bit add and you have a 64-bit type), then this will detect if an overflow occurred. My example is for an 8-bit add. But it can be scaled up.
uint8_t x, y; /* Give these values */
const uint16_t data16 = x + y;
const bool carry = (data16 > 0xFF);
const bool overflow = ((~(x ^ y)) & (x ^ data16) & 0x80);
It is based on the concepts explained on this page: http://www.cs.umd.edu/class/spring2003/cmsc311/Notes/Comb/overflow.html
For a 32-bit example, 0xFF
becomes 0xFFFFFFFF
and 0x80
becomes 0x80000000
and finally uint16_t
becomes a uint64_t
.
NOTE: this catches integer addition/subtraction overflows, and I realized that your question involves multiplication. In which case, division is likely the best approach. This is commonly a way that calloc
implementations make sure that the parameters don't overflow as they are multiplied to get the final size.
There are no security unless https is used - and with https, the transfer security is the same between GET and POST.
But one important aspect is the difference for client and server when it comes to remembering requests. This is very important to remember when considering GET or POST for a login.
With POST, the password is processed by the server application and then throw away, since a good design would not store passwords - only cryptographically secure hashes - in the database.
But with GET, the server log would end up containing the requests complete with the query parameters. So however good the password hashes in the database are, the server log would still contain passwords in clear text. And unless the file system is encrypted, the server disk would contain these passwords even after the log files have been erased.
The same problem happens when using access tokens as query parameters. And this is also a reason why it is meaningful to consider supplying any access token in the HTTP header data - such as by using a bearer token in the Authorization header.
The server logs are often the weakest part of a web service, allowing an attacker to elevate their access rights from leaked information.
Using jQuery Mask Plugin there is two possible ways to implement it:
1- Following Anatel's recomendations: https://gist.github.com/3724610/5003f97804ea1e62a3182e21c3b0d3ae3b657dd9
2- Or without following Anatel's recomendations: https://gist.github.com/igorescobar/5327820
All examples above was coded using jQuery Mask Plugin and it can be downloaded at: http://igorescobar.github.io/jQuery-Mask-Plugin/
Use below code for that

Use HH
for 24 hour hours format:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")
Or the tt
format specifier for the AM/PM
part:
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")
Take a look at the custom Date and Time format strings documentation.

Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
// Getting latitude of the current location
double latitude = location.getLatitude();
// Getting longitude of the current location

// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude);
myPosition = new LatLng(latitude, longitude);
googleMap.addMarker(new MarkerOptions().position(myPosition).title("Start"));

I used tmux-powerline to fully pimp my tmux status bar. I was googling for a way to change to background of the status bar when your typing a tmux command. When I stumbled on this post I thought I should mention it for completeness.
Update: This project is in a maintenance mode and no future functionality is likely to be added. tmux-powerline, with all other powerline projects, is replaced by the new unifying powerline. However this project is still functional and can serve as a lightweight alternative for non-python users.
Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)
Once you've generated your JSON, you can use something like the code below to POST it
StringRequestEntity requestEntity = new StringRequestEntity(
JSON_STRING,
"application/json",
"UTF-8");
PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);
int statusCode = httpClient.executeMethod(postMethod);
Edit
Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:
StringEntity requestEntity = new StringEntity(
JSON_STRING,
ContentType.APPLICATION_JSON);
HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);
HttpResponse rawResponse = httpclient.execute(postMethod);
Also you can keep clients refferences. But this makes your memmory busy.
Create an empty object and set your clients into it.
const myClientList = {};
server.on("connection", (socket) => {
console.info(`Client connected [id=${socket.id}]`);
myClientList[socket.id] = socket;
});
socket.on("disconnect", (socket) => {
delete myClientList[socket.id];
});
then call your specific client by id from the object
myClientList[specificId].emit("blabla","somedata");
I got it to work after I unchecked the following options in the Run/Debug Configurations for main.py

Add source roots to PYTHONPATH
This is after I had invalidated the cache and restarted.
At the current version of Spring-Boot (1.4.1.RELEASE) , each pooling datasource implementation has its own prefix for properties.
For instance, if you are using tomcat-jdbc:
spring.datasource.tomcat.max-wait=10000
You can find the explanation out here
spring.datasource.max-wait=10000
this have no effect anymore.
Within the package there is a class called JwtSecurityTokenHandler
which derives from System.IdentityModel.Tokens.SecurityTokenHandler
. In WIF this is the core class for deserialising and serialising security tokens.
The class has a ReadToken(String)
method that will take your base64 encoded JWT string and returns a SecurityToken
which represents the JWT.
The SecurityTokenHandler
also has a ValidateToken(SecurityToken)
method which takes your SecurityToken
and creates a ReadOnlyCollection<ClaimsIdentity>
. Usually for JWT, this will contain a single ClaimsIdentity
object that has a set of claims representing the properties of the original JWT.
JwtSecurityTokenHandler
defines some additional overloads for ValidateToken
, in particular, it has a ClaimsPrincipal ValidateToken(JwtSecurityToken, TokenValidationParameters)
overload. The TokenValidationParameters
argument allows you to specify the token signing certificate (as a list of X509SecurityTokens
). It also has an overload that takes the JWT as a string
rather than a SecurityToken
.
The code to do this is rather complicated, but can be found in the Global.asax.cx code (TokenValidationHandler
class) in the developer sample called "ADAL - Native App to REST service - Authentication with ACS via Browser Dialog", located at
http://code.msdn.microsoft.com/AAL-Native-App-to-REST-de57f2cc
Alternatively, the JwtSecurityToken
class has additional methods that are not on the base SecurityToken
class, such as a Claims
property that gets the contained claims without going via the ClaimsIdentity
collection. It also has a Payload
property that returns a JwtPayload
object that lets you get at the raw JSON of the token. It depends on your scenario which approach it most appropriate.
The general (i.e. non JWT specific) documentation for the SecurityTokenHandler
class is at
http://msdn.microsoft.com/en-us/library/system.identitymodel.tokens.securitytokenhandler.aspx
Depending on your application, you can configure the JWT handler into the WIF pipeline exactly like any other handler.
There are 3 samples of it in use in different types of application at
Probably, one will suite your needs or at least be adaptable to them.
I had the same issue. Fixed it by adding a static route on my host to my VM via the VMnet8 adapter:
route ADD VM_addr MASK 255.255.255.255 VMnet8_addr
As previously mentioned, you need a bridged connection.
try this,
EditText editText=(EditText)findViewById(R.id.editText1);

Here is the simplest solution w/o Service
nor Observer
:
Put the global variables in a file an export them.
//
// ===== File globals.ts
//
'use strict';
export const sep='/';
export const version: string="22.2.2";
To use globals in another file use an import
statement:
import * as myGlobals from 'globals';
Example:
//
// ===== File heroes.component.ts
//
import {Component, OnInit} from 'angular2/core';
import {Router} from 'angular2/router';
import {HeroService} from './hero.service';
import {HeroDetailComponent} from './hero-detail.component';
import {Hero} from './hero';
import * as myGlobals from 'globals'; //<==== this one (**Updated**)
export class HeroesComponent implements OnInit {
public heroes: Hero[];
public selectedHero: Hero;
//
//
// Here we access the global var reference.
//
public helloString: string="hello " + myGlobals.sep + " there";
...
}
}

I had a similar problem in IntelliJ IDEA. My code was 100% correct, but after starting the Tomcat, you receive an exception. java.lang.IllegalStateException: Neither BindingResult
I just removed and added again Tomcat configuration. And it worked for me.

You can also restrict keys to permissible commands (in the authorized_keys file).
I.e. the user would not log in via ssh and then have a restricted set of commands but rather would only be allowed to execute those commands via ssh (e.g. "ssh somehost bin/showlogfile")
You can use the standard HTML title attribute of image for this:
<img src="source of image" alt="alternative text" title="this will be displayed as a tooltip"/>
You have not defined the variable input_line
.
Add this:
string input_line;
And add this include.
#include <string>
Here is the full example. I also removed the semi-colon after the while loop, and you should have getline
inside the while to properly detect the end of the stream.
#include <iostream>
#include <string>
int main() {
for (std::string line; std::getline(std::cin, line);) {
std::cout << line << std::endl;
}
return 0;
}
I wrestled with this problem and implemented the URL concatenation solution contributed by @Kushan in the accepted answer above. It worked in my local MySql instance. But when I deployed my Play/Scala app to Heroku it no longer would work. Heroku also concatenates several args to the DB URL that they provide users, and this solution, because of Heroku's use concatenation of "?" before their own set of args, will not work. However I found a different solution which seems to work equally well.
SET sql_mode = 'NO_ZERO_DATE';
I put this in my table descriptions and it solved the problem of '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp
SilverSkin and Anders are both correct. You can use parentheses to execute multiple commands. However, you have to make sure that the commands themselves (and their parameters) do not contain parentheses. cmd
greedily searches for the first closing parenthesis, instead of handling nested sets of parentheses gracefully. This may cause the rest of the command line to fail to parse, or it may cause some of the parentheses to get passed to the commands (e.g. DEL myfile.txt)
).
A workaround for this is to split the body of the loop into a separate function. Note that you probably need to jump around the function body to avoid "falling through" into it.
FOR /r %%X IN (*.txt) DO CALL :loopbody %%X
REM Don't "fall through" to :loopbody.
GOTO :EOF
:loopbody
ECHO %1
DEL %1
GOTO :EOF
I have modified a bit the code above. for me 0 !== false and null !== undefined. If you do not need such strict check remove one "=" sign in "this[p] !== x[p]" inside the code.
Object.prototype.equals = function(x){
for (var p in this) {
if(typeof(this[p]) !== typeof(x[p])) return false;
if((this[p]===null) !== (x[p]===null)) return false;
switch (typeof(this[p])) {
case 'undefined':
if (typeof(x[p]) != 'undefined') return false;
break;
case 'object':
if(this[p]!==null && x[p]!==null && (this[p].constructor.toString() !== x[p].constructor.toString() || !this[p].equals(x[p]))) return false;
break;
case 'function':
if (p != 'equals' && this[p].toString() != x[p].toString()) return false;
break;
default:
if (this[p] !== x[p]) return false;
}
}
return true;
}
Then I have tested it with next objects:
var a = {a: 'text', b:[0,1]};
var b = {a: 'text', b:[0,1]};
var c = {a: 'text', b: 0};
var d = {a: 'text', b: false};
var e = {a: 'text', b:[1,0]};
var f = {a: 'text', b:[1,0], f: function(){ this.f = this.b; }};
var g = {a: 'text', b:[1,0], f: function(){ this.f = this.b; }};
var h = {a: 'text', b:[1,0], f: function(){ this.a = this.b; }};
var i = {
a: 'text',
c: {
b: [1, 0],
f: function(){
this.a = this.b;
}
}
};
var j = {
a: 'text',
c: {
b: [1, 0],
f: function(){
this.a = this.b;
}
}
};
var k = {a: 'text', b: null};
var l = {a: 'text', b: undefined};
a==b expected true; returned true
a==c expected false; returned false
c==d expected false; returned false
a==e expected false; returned false
f==g expected true; returned true
h==g expected false; returned false
i==j expected true; returned true
d==k expected false; returned false
k==l expected false; returned false
It will return 18 results starting on record #9 and finishing on record #26.
Start by reading the query from offset
. First you offset by 8, which means you skip the first 8 results of the query. Then you limit by 18. Which means you consider records 9, 10, 11, 12, 13, 14, 15, 16....24, 25, 26 which are a total of 18 records.
Check this out.
And also the official documentation.
Since you cannot have two methods with the same name and signature you have to use the ActionName
attribute:
[HttpGet]
public ActionResult Index()
{
// your code
return View();
}
[HttpPost]
[ActionName("Index")]
public ActionResult IndexPost()
{
// your code
return View();
}

I think you want to lowercase the checked value? Try:
var jIsHasKids = $('#chkIsHasKids:checked').val().toLowerCase();
or you want to check it, then get its value as lowercase:
var jIsHasKids = $('#chkIsHasKids').attr("checked", true).val().toLowerCase();
Nope, you've heard of MonoTouch which is a .NET/mono environment for iPhone development. But you still need a Mac and the official iPhone SDK. And the emulator is the official apple one, this acts as a separate IDE and allows you to not have to code in Objective C, rather you code in c#

1) Why does the x-axis (frequency) end at 500? How do I know that there aren't more frequencies or are they just ignored?
It ends at 500Hz because that is the Nyquist frequency of the signal when sampled at 1000Hz. Look at this line in the Mathworks example:
f = Fs/2*linspace(0,1,NFFT/2+1);
The frequency axis of the second plot goes from 0 to Fs/2, or half the sampling frequency. The Nyquist frequency is always half the sampling frequency, because above that, aliasing occurs:
The signal would "fold" back on itself, and appear to be some frequency at or below 500Hz.
2) How do I know the frequencies are between 0 and 500? Shouldn't the FFT tell me, in which limits the frequencies are?
Due to "folding" described above (the Nyquist frequency is also commonly known as the "folding frequency"), it is physically impossible for frequencies above 500Hz to appear in the FFT; higher frequencies will "fold" back and appear as lower frequencies.
Does the FFT only return the amplitude value without the frequency?
Yes, the MATLAB FFT function only returns one vector of amplitudes. However, they map to the frequency points you pass to it.
Let me know what needs clarification so I can help you further.

it saves your .bat file to "Appdata of current user" ,if it does not exist and remove the attributes and after that set the "hidden" attributes to file after writing your cmd code and run it silently and capture all output saves it to file so if u wanna save all output of cmd to file just add your like this
code > C:\Users\Lenovo\Desktop\output.txt
just replace word "code" with your .bat file code or command and after that the directory of output file I found one code recently after searching alot if u wanna run .bat file in vb or c# or simply just add this in the same manner in which i have written
The Problem of auto deintending is caused due to a checkbox being active in the settings of VSCode. Follow these steps:
A common practice is to hide joins in a view to present the user a more denormalized data model. Other uses involve security (for example by hiding certain columns and/or rows) or performance (in case of materialized views)
I have been practising working on files this evening and realised that I can build on Jochen's answer to provide greater functionality for repeated/multiple use. Unfortunately my answer does not address issue of dealing with large files but does make life easier in smaller files.
with open('filetochange.txt', 'r+') as foo:
data = foo.readlines() #reads file as list
pos = int(input("Which position in list to edit? "))-1 #list position to edit
data.insert(pos, "more foo"+"\n") #inserts before item to edit
x = data[pos+1]
data.remove(x) #removes item to edit
foo.seek(0) #seeks beginning of file
for i in data:
i.strip() #strips "\n" from list items
foo.write(str(i))

I rewrote David's answer using the with
statement, it allows you do do this:
with timeout(seconds=3):
time.sleep(4)
Which will raise a TimeoutError.
The code is still using signal
and thus UNIX only:
import signal
class timeout:
def __init__(self, seconds=1, error_message='Timeout'):
self.seconds = seconds
self.error_message = error_message
def handle_timeout(self, signum, frame):
raise TimeoutError(self.error_message)
def __enter__(self):
signal.signal(signal.SIGALRM, self.handle_timeout)
signal.alarm(self.seconds)
def __exit__(self, type, value, traceback):
signal.alarm(0)
My finally working approach is to try potential candidates of expected encodings by detecting invalid characters in the strings created from the byte array by the encodings. If I don't encounter invalid characters, I suppose the tested encoding works fine for the tested data.
For me, having only Latin and German special characters to consider, in order to determine the proper encoding for a byte array, I try to detect invalid characters in a string with this method:
/// <summary>
/// detect invalid characters in string, use to detect improper encoding
/// </summary>
/// <param name="s"></param>
/// <returns></returns>
public static bool DetectInvalidChars(string s)
{
const string specialChars = "\r\n\t .,;:-_!\"'?()[]{}&%$§=*+~#@|<>äöüÄÖÜß/\\^€";
return s.Any(ch => !(
specialChars.Contains(ch) ||
(ch >= '0' && ch <= '9') ||
(ch >= 'a' && ch <= 'z') ||
(ch >= 'A' && ch <= 'Z')));
}
(NB: if you have other Latin-based languages to consider, you might want to adapt the specialChars const string in the code)
Then I use it like this (I only expect UTF-8 or Default encoding):
// determine encoding by detecting invalid characters in string
var invoiceXmlText = Encoding.UTF8.GetString(invoiceXmlBytes); // try utf-8 first
if (StringFuncs.DetectInvalidChars(invoiceXmlText))
invoiceXmlText = Encoding.Default.GetString(invoiceXmlBytes); // fallback to default
Just had this issue deploying a new app to an old IIS box. The investigation led to the v4.5.1 run-time being installed but the app requiring v4.5.2
Nothing apart from installing the correct version of ASP .Net run-time was required.
Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.
Gantt chart for this ques will be:
| P3 | P2 | P4 | P5 | P1 |
1 4 5 7 11 14
Average waiting time=(0+2+2+3+3)/5=2
Average Turnaround time=(3+3+4+7+6)/5=4.6
Alternatives:
>>> map(a.__getitem__, b)
[1, 5, 5]
>>> import operator
>>> operator.itemgetter(*b)(a)
(1, 5, 5)
Certainly the credit goes to @Harvey Kwok here, but I just wanted to add this example because in my case I wanted to get an actual List of UserPrincipals. It's probably more efficient to filter this query upfront, but in my small environment, it's just easier to pull everything and then filter as needed later from my list.
Depending on what you need, you may not need to cast to DirectoryEntry, but some properties are not available from UserPrincipal.
using (var searcher = new PrincipalSearcher(new UserPrincipal(new PrincipalContext(ContextType.Domain, Environment.UserDomainName))))
{
List<UserPrincipal> users = searcher.FindAll().Select(u => (UserPrincipal)u).ToList();
foreach(var u in users)
{
DirectoryEntry d = (DirectoryEntry)u.GetUnderlyingObject();
Console.WriteLine(d.Properties["GivenName"]?.Value?.ToString() + d.Properties["sn"]?.Value?.ToString());
}
}
playSound is a static method in your class, but you are referring to members like audioSounds
or minTime
which are not declared static
so they would require a SoundManager sm = new SoundManager();
to operate as sm.audioSounds
or sm.minTime
respectively
Solution:
public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;
$("#button_id").click(function(){ $("#detailInfo").html("WHAT YOU WANT") })
With styled components this can be easily achieved

margin: 1em;
padding: 0.25em 1em;
border: 2px solid red;
border-radius: 3px;
`
render(
<Button as={Link} to="/home"> Text Goes Here </Button>
);

As Jordan already said you have to post back the javascript variable to your server before the server can handle the value. To do this you can either program a javascript function that submits a form - or you can use ajax / jquery. jQuery.post
Maybe the most easiest approach for you is something like this
function myJavascriptFunction() {
var javascriptVariable = "John";
window.location.href = "myphpfile.php?name=" + javascriptVariable;
}
On your myphpfile.php you can use $_GET['name']
after your javascript was executed.

One area where I found mmap() to not be an advantage was when reading small files (under 16K). The overhead of page faulting to read the whole file was very high compared with just doing a single read() system call. This is because the kernel can sometimes satisify a read entirely in your time slice, meaning your code doesn't switch away. With a page fault, it seemed more likely that another program would be scheduled, making the file operation have a higher latency.
It's been a while since I read it (so, I'm not sure how much of it is still relevant), but my recollection is that Joe Celko's SQL for Smarties book provides a lot of info on writing elegant, effective, and efficient queries.
Not sure about your specific scenario, but you have three options:
1.) use Dictionary<..,..>
2.) create a wrapper class around your values and then you can use List
3.) use Tuple
Here we use onkeyup event in input field which triggered when the user releases a Key. And here we change our value to uppercase by toUpperCase() function.
Note that, text-transform="Uppercase" will only change the text in style. but not it's value. So,In order to change value, Use this inline code that will show as well as change the value
<input id="test-input" type="" name="" onkeyup="this.value = this.value.toUpperCase();">
Here is the code snippet that proved the value is change

Checking for nothing/Null is the way to do it.
Dealing with object types is not the way to go. Declare a strict type and try to cast the object to the correct type. (And use cast hint or Convert)
private const string SESSION_VAR = "myString";
string sSession;
if (Session[SESSION_VAR] != null)
{
sSession = (string)Session[SESSION_VAR];
}
else
{
sSession = "set this";
Session[SESSION_VAR] = sSession;
}

It doesn't take the 50% of the whole page is because the "whole page" is only how tall your contents are. Change the enclosing html
and body
to 100%
height and it will work.
html, body{
height: 100%;
}
div{
height: 50%;
}
http://jsfiddle.net/DerekL/5YukJ/1/
^ Your document is only 20px high. 50% of 20px is 10px, and it is not what you expected.
^ Now if you change the height of the document to the height of the whole page (150px), 50% of 150px is 75px, then it will work.
This is a response I got from their Premium Services
Hello,
This is actually a issue with the way SSL validates names containing a period, '.', > character. We've documented this behavior here:
http://docs.amazonwebservices.com/AmazonS3/latest/dev/BucketRestrictions.html
The only straight-forward fix for this is to use a bucket name that does not contain that character. You might instead use a bucket named 'furniture-retailcatalog-us'. This would allow you use HTTPS with
https://furniture-retailcatalog-us.s3.amazonaws.com/
You could, of course, put a CNAME DNS record to make that more friendly. For example,
images-furniture.retailcatalog.us IN CNAME furniture-retailcatalog-us.s3.amazonaws.com.
Hope that helps. Let us know if you have any other questions.
Amazon Web Services
Unfortunately your "friendly" CNAME will cause host name mismatch when validating the certificate, therefore you cannot really use it for a secure connection. A big missing feature of S3 is accepting custom certificates for your domains.
UPDATE 10/2/2012
From @mpoisot:
The link Amazon provided no longer says anything about https. I poked around in the S3 docs and finally found a small note about it on the Virtual Hosting page: http://docs.amazonwebservices.com/AmazonS3/latest/dev/VirtualHosting.html

As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2)
as a simple alternative. Here's a more advanced mtext() example:
set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
yaxt="n", ylab="",
xlab="Regular boring x",
pch=16,
col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)
You may need to adjust the line=
option to get the optimal positioning of the text but apart from that it's really easy to use.
Put this in filename.txt
:
abc
def
ghi
jkl
grep command using -E option with a pipe between tokens in a string:
grep -Ev 'def|jkl' filename.txt
prints:
abc
ghi
Command using -v option with pipe between tokens surrounded by parens:
egrep -v '(def|jkl)' filename.txt
prints:
abc
ghi
The two snippets do different things, so it's not a matter of taste but a matter of what's the right behaviour in your context. Python documentation explains the difference, but here are some examples:
class Foo:
def __init__(self):
self.num = 1
This binds num
to the Foo instances. Change to this field is not propagated to other instances.
Thus:
>>> foo1 = Foo()
>>> foo2 = Foo()
>>> foo1.num = 2
>>> foo2.num
1
class Bar:
num = 1
This binds num
to the Bar class. Changes are propagated!
>>> bar1 = Bar()
>>> bar2 = Bar()
>>> bar1.num = 2 #this creates an INSTANCE variable that HIDES the propagation
>>> bar2.num
1
>>> Bar.num = 3
>>> bar2.num
3
>>> bar1.num
2
>>> bar1.__class__.num
3
If I do not require a class variable, but only need to set a default value for my instance variables, are both methods equally good? Or one of them more 'pythonic' than the other?
The code in exhibit B is plain wrong for this: why would you want to bind a class attribute (default value on instance creation) to the single instance?
The code in exhibit A is okay.
If you want to give defaults for instance variables in your constructor I would however do this:
class Foo:
def __init__(self, num = None):
self.num = num if num is not None else 1
...or even:
class Foo:
DEFAULT_NUM = 1
def __init__(self, num = None):
self.num = num if num is not None else DEFAULT_NUM
...or even: (preferrable, but if and only if you are dealing with immutable types!)
class Foo:
def __init__(self, num = 1):
self.num = num
This way you can do:
foo1 = Foo(4)
foo2 = Foo() #use default
Use android vollley, it is very fast and you can betterm manipulate requests. Send post request using Volley and receive in PHP
Basically, you will create a map with key-value params for the php request(POST/GET), the php will do the desired processing and you will return the data as JSON(json_encode()). Then you can either parse the JSON as needed or use GSON from Google to let it do the parsing.

Hello from the future.
For clarity, I just wanted to add (as this was pretty high up in google) - we can now use
<button type="submit">Upload Stuff</button>
And to reset a form
<button type="reset" value="Reset">Reset</button>
Check out button types
We can also attach buttons to submit forms like this:
<button type="submit" form="myform" value="Submit">Submit</button>
arrayList.toArray(new Custom[0]);
This is a quirk of the C grammar. A label (Cleanup:
) is not allowed to appear immediately before a declaration (such as char *str ...;
), only before a statement (printf(...);
). In C89 this was no great difficulty because declarations could only appear at the very beginning of a block, so you could always move the label down a bit and avoid the issue. In C99 you can mix declarations and code, but you still can't put a label immediately before a declaration.
You can put a semicolon immediately after the label's colon (as suggested by Renan) to make there be an empty statement there; this is what I would do in machine-generated code. Alternatively, hoist the declaration to the top of the function:
int main (void)
{
char *str;
printf("Hello ");
goto Cleanup;
Cleanup:
str = "World\n";
printf("%s\n", str);
return 0;
}
See man git-add
:
-f, --force
Allow adding otherwise ignored files.
So run this
git add --force my/ignore/file.foo
You should not use your domain models
in your views. ViewModels
are the correct way to do it.
You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.
If you never heard of viewmodels, take a look at this.
phc allows you to compile PHP programs into shared libraries, which can be uploaded to the server. The PHP program is compiled into binaries. It's done in such a way as to support eval

s, and the entire PHP standard library.
Map.values()

I have seen this problem when the user had set up a scheduled task to run under his account. He forgot to update the password on the task after he changed his account password. The scheduled task was trying to logon with the old password and kept locking out his account.
try to do this in the behind code
public diagboxclass()
{
List<object> list = new List<object>();
list = GetObjectList();
Imported.ItemsSource = null;
Imported.ItemsSource = list;
}
Also be sure your list is effectively populated and as mentioned by Blindmeis, never use words that already are given a function in c#.
If you want to remove an item, the following will be a bit more efficient.
std::vector<int> v;
auto it = std::find(v.begin(), v.end(), 5);
if(it != v.end())
v.erase(it);
or you may avoid overhead of moving the items if the order does not matter to you:
std::vector<int> v;
auto it = std::find(v.begin(), v.end(), 5);
if (it != v.end()) {
using std::swap;
// swap the one to be removed with the last element
// and remove the item at the end of the container
// to prevent moving all items after '5' by one
swap(*it, v.back());
v.pop_back();
}
Excerpt from my Blog-Note-to-myself:
Now you can import a dump file e.g. if you are migrating between machines / subversion versions. e.g. if I had created a dump file from the source repository and load it into the new repository as shown below.
Commands for Unix-like systems (from terminal):
svnadmin dump /path/to/your/old/repo > backup.dump
svnadmin load /path/to/your/new/repo < backup.dump.dmp
Commands for Microsoft Windows systems (from cmd shell):
svnadmin dump C:\path\to\your\old\repo > backup.dump
svnadmin load C:\path\to\your\old\repo < backup.dump
Scrolling with animation:
Your DIV:
<div class='messageScrollArea' style='height: 100px;overflow: auto;'>
Hello World! Hello World! Hello World! Hello World! Hello World! Hello
Hello World! Hello World! Hello World! Hello World! Hello World! Hello
Hello World! Hello World! Hello World! Hello World! Hello World! Hello
</div>
jQuery part:
jQuery(document).ready(function(){
var $t = $('.messageScrollArea');
$t.animate({"scrollTop": $('.messageScrollArea')[0].scrollHeight}, "slow");
});
Alternative solution that uses .query() method:
In [5]: df.query("countries in @countries")
Out[5]:
countries
1 UK
3 China
In [6]: df.query("countries not in @countries")
Out[6]:
countries
0 US
2 Germany
Just use DROP TABLE IF EXISTS
:
DROP TABLE IF EXISTS `foo`;
CREATE TABLE `foo` ( ... );
Try searching the MySQL documentation first if you have any other problems.
If you want to use the numbers
method, you need an int array to store the returned value.
public static void main(String[] args){
int[] someNumbers = numbers();
//do whatever you want with them...
System.out.println(Arrays.toString(someNumbers));
}
or you can simply use
def question_params
params.require(:question).permit(team_ids: [])
end
With the help of ProgrammersBlock posts I came up with this. My needs were slightly different. I needed to take a string and return it as a LocalDate object. I was handed code that was using the older Calendar and SimpleDateFormat. I wanted to make it a little more current. This is what I came up with.
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
void ExampleFormatDate() {
LocalDate formattedDate = null; //Declare LocalDate variable to receive the formatted date.
DateTimeFormatter dateTimeFormatter; //Declare date formatter
String rawDate = "2000-01-01"; //Test string that holds a date to format and parse.
dateTimeFormatter = DateTimeFormatter.ISO_LOCAL_DATE;
//formattedDate.parse(String string) wraps the String.format(String string, DateTimeFormatter format) method.
//First, the rawDate string is formatted according to DateTimeFormatter. Second, that formatted string is parsed into
//the LocalDate formattedDate object.
formattedDate = formattedDate.parse(String.format(rawDate, dateTimeFormatter));
}
Hopefully this will help someone, if anyone sees a better way of doing this task please add your input.
This is easy. You just need to put inside .form-control
this:
.form-control{
-webkit-appearance:none;
-moz-appearance: none;
-ms-appearance: none;
-o-appearance: none;
appearance: none;
}
This will remove browser's appearance and allow your CSS.
A void*
pointer is used when you want to indicate a pointer to a hunk of memory without specifying the type. C's malloc
returns such a pointer, expecting you to cast it to a particular type immediately. It really isn't useful until you cast it to another pointer type. You're expected to know which type to cast it to, the compiler has no reflection capability to know what the underlying type should be.
Is very easy, this work for me:
PHP:
set_time_limit(300); // Time in seconds, max_execution_time
Here is the PHP documentation
This goes also for statements like this (auto-formatted by PyCharm):
return combine_sample_generators(sample_generators['train']), \
combine_sample_generators(sample_generators['dev']), \
combine_sample_generators(sample_generators['test'])
Which will give the same style-warning. In order to get rid of it I had to rewrite it to:
return \
combine_sample_generators(sample_generators['train']), \
combine_sample_generators(sample_generators['dev']), \
combine_sample_generators(sample_generators['test'])
Looking at posted answers I think this code would be also an alternative for someone. Nobody above used .Shapes.AddPicture
in their code, only .Pictures.Insert()
Dim myPic As Object
Dim picpath As String
picpath = "C:\Users\photo.jpg" 'example photo path
Set myPic = ws.Shapes.AddPicture(picpath, False, True, 20, 20, -1, -1)
With myPic
.Width = 25
.Height = 25
.Top = xlApp.Cells(i, 20).Top 'according to variables from correct answer
.Left = xlApp.Cells(i, 20).Left
.LockAspectRatio = msoFalse
End With
I'm working in Excel 2013. Also realized that You need to fill all the parameters in .AddPicture
, because of error "Argument not optional". Looking at this You may ask why I set Height
and Width
as -1, but that doesn't matter cause of those parameters are set underneath between With
brackets.
Hope it may be also useful for someone :)
You could try to extract columns as list, massage this as you want, and reindex your dataframe:
>>> cols = df.columns.tolist()
>>> cols = [cols[-1]]+cols[:-1] # or whatever change you need
>>> df.reindex(columns=cols)
n l v
0 0 a 1
1 0 b 2
2 0 c 1
3 0 d 2
EDIT: this can be done in one line ; however, this looks a bit ugly. Maybe some cleaner proposal may come...
>>> df.reindex(columns=['n']+df.columns[:-1].tolist())
n l v
0 0 a 1
1 0 b 2
2 0 c 1
3 0 d 2
My pod kept crashing and I was unable to find the cause. Luckily there is a space where kubernetes saves all the events that occurred before my pod crashed.
(#List Events sorted by timestamp)
To see these events run the command:
kubectl get events --sort-by=.metadata.creationTimestamp
make sure to add a --namespace mynamespace
argument to the command if needed
The events shown in the output of the command showed my why my pod kept crashing.
Lets try to answer this question, with a good and simple scenario, with 3 MySQL
tables i.e. datetable, colortable and jointable.
first see values of table
datetable with primary key
assigned to column
dateid:
mysql> select * from datetable;
+--------+------------+
| dateid | datevalue |
+--------+------------+
| 101 | 2015-01-01 |
| 102 | 2015-05-01 |
| 103 | 2016-01-01 |
+--------+------------+
3 rows in set (0.00 sec)
now move to our second table
values colortable with primary key
assigned to column
colorid:
mysql> select * from colortable;
+---------+------------+
| colorid | colorvalue |
+---------+------------+
| 11 | blue |
| 12 | yellow |
+---------+------------+
2 rows in set (0.00 sec)
and our final third table
jointable have no primary keys
and values are:
mysql> select * from jointable;
+--------+---------+
| dateid | colorid |
+--------+---------+
| 101 | 11 |
| 102 | 12 |
| 101 | 12 |
+--------+---------+
3 rows in set (0.00 sec)
Now our condition is to find the dateid's, which have both color values blue and yellow.
So, our query is:
mysql> SELECT t1.dateid FROM jointable AS t1 INNER JOIN jointable t2
-> ON t1.dateid = t2.dateid
-> WHERE
-> (t1.colorid IN (SELECT colorid FROM colortable WHERE colorvalue = 'blue'))
-> AND
-> (t2.colorid IN (SELECT colorid FROM colortable WHERE colorvalue = 'yellow'));
+--------+
| dateid |
+--------+
| 101 |
+--------+

Css is going to work in same manner i assume.
You can center the content with something like this :
.center{
text-align:center;
}
Update
To adjust the width in proper manner, modify your DOM as below :
<div class="item-input-inset">
<label class="item-input-wrapper"> Date
<input type="text" placeholder="Text Area" />
</label>
</div>
<div class="item-input-inset">
<label class="item-input-wrapper"> Suburb
<input type="text" placeholder="Text Area" />
</label>
</div>
CSS
label {
display:inline-block;
border:1px solid red;
width:100%;
font-weight:bold;
}
input{
float:right; /* shift to right for alignment*/
width:80% /* set a width, you can use max-width to limit this as well*/
}
final update
If you don't plan to modify existing HTML (one in your question originally), below css would make me your best friend!! :)
html, body, .con {
height:100%;
margin:0;
padding:0;
}
.item-input-inset {
display:inline-block;
width:100%;
font-weight:bold;
}
.item-input-inset > h4 {
float:left;
margin-top:0;/* important alignment */
width:15%;
}
.item-input-wrapper {
display:block;
float:right;
width:85%;
}
input {
width:100%;
}
Since your content-type is application/x-www-form-urlencoded
you'll need to encode the POST body, especially if it contains characters like &
which have special meaning in a form.
Try passing your string through HttpUtility.UrlEncode before writing it to the request stream.
Here are a couple links for reference.
I'm surprised nobody has given this answer, it's the simplest one. (Must be the year.)
Just Shift + right click in Explorer. Then you can "Open PowerShell window here".
It may be set to Command Prompt by default. If so, you can change this in the Windows 10 Settings: go to Personalization -> Taskbar and enable "Replace Command Prompt with Windows PowerShell in the menu when I right-click the start button or press Windows key+X".
From find manual:
NON-BUGS
Operator precedence surprises
The command find . -name afile -o -name bfile -print will never print
afile because this is actually equivalent to find . -name afile -o \(
-name bfile -a -print \). Remember that the precedence of -a is
higher than that of -o and when there is no operator specified
between tests, -a is assumed.
“paths must precede expression” error message
$ find . -name *.c -print
find: paths must precede expression
Usage: find [-H] [-L] [-P] [-Olevel] [-D ... [path...] [expression]
This happens because *.c has been expanded by the shell resulting in
find actually receiving a command line like this:
find . -name frcode.c locate.c word_io.c -print
That command is of course not going to work. Instead of doing things
this way, you should enclose the pattern in quotes or escape the
wildcard:
$ find . -name '*.c' -print
$ find . -name \*.c -print
Here's an example that puts the Now()
value in column A.
Sub move()
Dim i As Integer
Dim sh1 As Worksheet
Dim sh2 As Worksheet
Dim nextRow As Long
Dim copyRange As Range
Dim destRange As Range
Application.ScreenUpdating = False
Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
Set copyRange = sh1.Range("A1:A5")
i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4
Set destRange = sh2.Range("B" & i)
destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")
copyRange.Clear
Application.ScreenUpdating = True
End Sub
There are better ways of getting the last row in column B than using a While
loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3
have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)
Add code in /wp-content/plugins/woocommerce/templates/
loop path
<?php
if ( is_product_category() ){
global $wp_query;
$cat = $wp_query->get_queried_object();
$thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
echo "<img src='{$image}' alt='' />";
}
?>
I'd suggest:
document.querySelector('.rateRecipe.btns-one-small').click();
The above code assumes that the given element has both of those classes; otherwise, if the space is meant to imply an ancestor-descendant relationship:
document.querySelector('.rateRecipe .btns-one-small').click();
The method getElementsByClassName()
takes a single class-name (rather than document.querySelector()
/document.querySelectorAll()
, which take a CSS selector), and you passed two (presumably class-names) to the method.

For anyone checking this question recently, Rails 5.2+ now has ActiveStorage by default & I highly recommend checking it out.
Since it is part of the core Rails 5.2+ now, it is very well integrated & has excellent capabilities out of the box (still all other well-known gems like Carrierwave, Shrine, paperclip,... are great but this one offers very good features that we can consider for any new Rails project)
Paperclip team deprecated the gem in favor of the Rails ActiveStorage.
Here is the github page for the ActiveStorage & plenty of resources are available everywhere
Also I found this video to be very helpful to understand the features of Activestorage
I think you try something like
@if(!$result->isEmpty())
// $result is not empty
@else
// $result is empty
@endif
or also use
if (!$result) { }
if ($result) { }
I am using git-bash in windows.The simplest way is to change the path address to have the forward slashes:
git clone C:/Dev/proposed
P.S: Start the git-bash on the destination folder.
Path used in clone ---> c:/Dev/proposed
Original path in windows ---> c:\Dev\proposed
If you plan on deleting or renaming a table or column finding only foreign key dependencies might not be enough.
Referencing tables not connected with foreign key - You’ll also need to search for referencing tables that might not be connected with foreign key (I’ve seen many databases with bad design that didn’t have foreign keys defined but that did have related data). Solution might be to search for column name in all tables and look for similar columns.
Other database objects – this is probably a bit off topic but if you were looking for all references than it’s also important to check for dependent objects.
GUI Tools – Try SSMS “Find related objects” option or tools such as ApexSQL Search (free tool, integrates into SSMS) to identify all dependent objects including tables connected with foreign key.
These answers were helpful in solving a similar issue while trying to define a named range with Workbook
scope. The "ah-HA!" for me is to use the Names Collection which is relative to the whole Workbook! This may be restating the obvious to many, but it wasn't clearly stated in my research, so I share for other's with similar questions.
' Local / Worksheet only scope
Worksheets("Sheet2").Names.Add Name:="a_test_rng1", RefersTo:=Range("A1:A4")
' Global / Workbook scope
ThisWorkbook.Names.Add Name:="a_test_rng2", RefersTo:=Range("B1:b4")
If you look at your list of names when Sheet2 is active, both ranges are there, but switch to any other sheet, and "a_test_rng1"
is not present.
Now I can happily generate a named range in my code with what ever scope I deem appropriate. No need mess around with the name manager or a plug in.
Aside, the name manager in Excel Mac 2011 is a mess, but I did discover that while there are no column labels to tell you what you're looking at while viewing your list of named ranges, if there is a sheet listed beside the name, that name is scoped to worksheet / local. See screenshot attached.
Full credit to this article for putting together the pieces.
What you want to use is this property:

We chose a combination of Mongo/Dynamo for a healthcare product. Basically mongo allows better searching, but the hosted Dynamo is great because its HIPAA compliant without any extra work. So we host the mongo portion with no personal data on a standard setup and allow amazon to deal with the HIPAA portion in terms of infrastructure. We can query certain items from mongo which bring up documents with pointers (ID's) of the relatable Dynamo document.
The main reason we chose to do this using mongo instead of hosting the entire application on dynamo was for 2 reasons. First, we needed to preform location based searches which mongo is great at and at the time, Dynamo was not, but they do have an option now.
Secondly was that some documents were unstructured and we did not know ahead of time what the data would be, so for example lets say user a inputs a document in the "form" collection like this: {"username": "user1", "email": "[email protected]"}. And another user puts this in the same collection {"phone": "813-555-3333", "location": [28.1234,-83.2342]}. With mongo we can search any of these dynamic and unknown fields at any time, with Dynamo, you could do this but would have to make a index every time a new field was added that you wanted searchable. So if you have never had a phone field in your Dynamo document before and then all of the sudden, some one adds it, its completely unsearchable.
Now this brings up another point in which you have mentioned. Sometimes choosing the right solution for the job does not always mean choosing the best product for the job. For example you may have a client who needs and will use the system you created for 10+ years. Going with a SaaS/IaaS solution that is good enough to get the job done may be a better option as you can rely on amazon to have up-kept and maintained their systems over the long haul.
Open with append:
pFile2 = fopen("myfile2.txt", "a");
then just write to pFile2

If you want to run your script from a desktop shortcut, right click your python file and select Send to|Desktop (create shortcut)
. Then right click the shortcut and select Properties. On the Shortcut tab select the Target: text box and add cmd /k
in front of the path and click OK. The shortcut should now run your script without closing and you don't need the input('Hit enter to close')
Note, if you have more than one version of python on your machine, add the name of the required python executable between cmd /k and the scipt path like this:
cmd /k python3 "C:\Users\<yourname>\Documents\your_scipt.py"
"Support for DEFAULT in TEXT/BLOB columns" is a feature request in the MySQL Bugtracker (Bug #21532).
I see I'm not the only one who would like to put a default value in a TEXT column. I think this feature should be supported in a later version of MySQL.
This can't be fixed in the version 5.0 of MySQL, because apparently it would cause incompatibility and dataloss if anyone tried to transfer a database back and forth between the (current) databases that don't support that feature and any databases that did support that feature.
You can also try /etc/redhat-release

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron
. Hence, do install it with:
yum install vixie-cron
And then start it with:
service crond start
To make it persistent, so that it starts on boot, use:
chkconfig crond on
On CentOS 7 you need to use cronie
:
yum install cronie
On CentOS 6 you can install vixie-cron
, but the real package is cronie
:
yum install vixie-cron
and
yum install cronie
In both cases you get the same output:

You'd better use CSS for this:
td{
background-color:black;
color:white;
}
td:hover{
background-color:white;
color:black;
}
If you want to use these styles for only a specific set of elements, you should give your td
a class (or an ID, if it's the only element which'll have that style).
Example :
<td class="whiteHover"></td>
.whiteHover{
/* Same style as above */
}
Here's a reference on MDN for :hover
pseudo class.
let plainString = "foo"
let plainData = plainString.data(using: .utf8)
let base64String = plainData?.base64EncodedString()
print(base64String!) // Zm9v
if let decodedData = Data(base64Encoded: base64String!),
let decodedString = String(data: decodedData, encoding: .utf8) {
print(decodedString) // foo
}
let plainString = "foo"
let plainData = plainString.dataUsingEncoding(NSUTF8StringEncoding)
let base64String = plainData?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
print(base64String!) // Zm9v
let decodedData = NSData(base64EncodedString: base64String!, options: NSDataBase64DecodingOptions(rawValue: 0))
let decodedString = NSString(data: decodedData, encoding: NSUTF8StringEncoding)
print(decodedString) // foo
NSString *plainString = @"foo";
NSData *plainData = [plainString dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64String = [plainData base64EncodedStringWithOptions:0];
NSLog(@"%@", base64String); // Zm9v
NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:base64String options:0];
NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];
NSLog(@"%@", decodedString); // foo
Another possible solution that is not mentioned above is to check your remote with the following command:
git remote -v
If the remote does not start with git but starts with https you might want to change it to git by following the example below.
git remote -v // origin is https://github.com/user/myrepo.git
git remote set-url origin [email protected]:user/myrepo.git
git remote -v // check if remote is changed
Re: craigts's response, for anyone having trouble with using either False or None parameters for index_col, such as in cases where you're trying to get rid of a range index, you can instead use an integer to specify the column you want to use as the index. For example:
df = pd.read_csv('file.csv', index_col=0)
The above will set the first column as the index (and not add a range index in my "common case").
Given the popularity of this answer, I thought i'd add some context/ a demo:
# Setting up the dummy data
In [1]: df = pd.DataFrame({"A":[1, 2, 3], "B":[4, 5, 6]})
In [2]: df
Out[2]:
A B
0 1 4
1 2 5
2 3 6
In [3]: df.to_csv('file.csv', index=None)
File[3]:
A B
1 4
2 5
3 6
Reading without index_col or with None/False will all result in a range index:
In [4]: pd.read_csv('file.csv')
Out[4]:
A B
0 1 4
1 2 5
2 3 6
# Note that this is the default behavior, so the same as In [4]
In [5]: pd.read_csv('file.csv', index_col=None)
Out[5]:
A B
0 1 4
1 2 5
2 3 6
In [6]: pd.read_csv('file.csv', index_col=False)
Out[6]:
A B
0 1 4
1 2 5
2 3 6
However, if we specify that "A" (the 0th column) is actually the index, we can avoid the range index:
In [7]: pd.read_csv('file.csv', index_col=0)
Out[7]:
B
A
1 4
2 5
3 6
Notice you can use WHEN exception THEN NULL
the same way as you would use WHEN exception THEN continue
. Example:
DECLARE
extension_already_exists EXCEPTION;
PRAGMA EXCEPTION_INIT(extension_already_exists, -20007);
l_hidden_col_name varchar2(32);
BEGIN
FOR t IN ( SELECT table_name, cast(extension as varchar2(200)) ext
FROM all_stat_extensions
WHERE owner='{{ prev_schema }}'
and droppable='YES'
ORDER BY 1
)
LOOP
BEGIN
l_hidden_col_name := dbms_stats.create_extended_stats('{{ schema }}', t.table_name, t.ext);
EXCEPTION
WHEN extension_already_exists THEN NULL; -- ignore exception and go to next loop iteration
END;
END LOOP;
END;
Use the following to convert uint8 array to base64 encoded string
function arrayBufferToBase64(buffer) {
var binary = '';
var bytes = [].slice.call(new Uint8Array(buffer));
bytes.forEach((b) => binary += String.fromCharCode(b));
return window.btoa(binary);
};
I'm not sure if you're going to get any huge gains for reasons Jon Skeet pointed out. However, you could try and benchmark the TypeConvert.ConvertTo method and see how it compares to using your current method.
ImageConverter converter = new ImageConverter();
byte[] imgArray = (byte[])converter.ConvertTo(imageIn, typeof(byte[]));
In my opinion, this is the simplest way to join two tables with multiple fields:
from a in Table1 join b in Table2
on (a.Field1.ToString() + "&" + a.Field2.ToString())
equals (b.Field1.ToString() + "&" + b.Field2.ToString())
select a
Yes its possible! and you can use as many colors and images as you desire, here is the right way:
body{_x000D_
/* Its, very important to set the background repeat to: no-repeat */_x000D_
background-repeat:no-repeat; _x000D_
_x000D_
background-image: _x000D_
/* 1) An image */ url(http://lorempixel.com/640/100/nature/John3-16/), _x000D_
/* 2) Gradient */ linear-gradient(to right, RGB(0, 0, 0), RGB(255, 255, 255)), _x000D_
/* 3) Color(using gradient) */ linear-gradient(to right, RGB(110, 175, 233), RGB(110, 175, 233));_x000D_
_x000D_
background-position:_x000D_
/* 1) Image position */ 0 0, _x000D_
/* 2) Gradient position */ 0 100px,_x000D_
/* 3) Color position */ 0 130px;_x000D_
_x000D_
background-size: _x000D_
/* 1) Image size */ 640px 100px,_x000D_
/* 2) Gradient size */ 100% 30px, _x000D_
/* 3) Color size */ 100% 30px;_x000D_
}
_x000D_
both your conditions are the same:
if(s < f) { calc = f - s; n = s; }else if(f > s){ calc = s - f; n = f; }
so
if(s < f)
and
}else if(f > s){
are the same
change to
}else if(f < s){
This solutions working for me,
let params = new HttpParams();
Object.keys(data).forEach(p => {
params = params.append(p.toString(), data[p].toString());
});
You can use the sDom
option for this.
Default with search input in its own div:
sDom: '<"search-box"r>lftip'
If you use jQuery UI (bjQueryUI
set to true
):
sDom: '<"search-box"r><"H"lf>t<"F"ip>'
The above will put the search/filtering input
element into it's own div
with a class named search-box
that is outside of the actual table.
Even though it uses its special shorthand syntax it can actually take any HTML you throw at it.
The TabPage class hides the Enabled property. That was intentional as there is an awkward UI design problem with it. The basic issue is that disabling the page does not also disable the tab. And if try to work around that by disabling the tab with the Selecting event then it does not work when the TabControl has only one page.
If these usability problems do not concern you then keep in mind that the property still works, it is merely hidden from IntelliSense. If the FUD is uncomfortable then you can simply do this:
public static void EnableTab(TabPage page, bool enable) {
foreach (Control ctl in page.Controls) ctl.Enabled = enable;
}
You can use the BeforeClass
annotation:
@BeforeClass
public static void setUpClass() {
//executed only once, before the first test
}
You can use the NSThread
method:
[NSThread sleepForTimeInterval: delay];
However, if you do this on the main thread you'll block the app, so only do this on a background thread.
or in Swift
NSThread.sleepForTimeInterval(delay)
in Swift 3
Thread.sleep(forTimeInterval: delay)
You need to use the change directory command 'cd' to change directory
cd C:\Users\MyName\Desktop
you can use cd \d
to change the drive as well.
link for additional resources http://ss64.com/nt/cd.html
Wasted a lot of time on this silly issue!
add a cd command to where your batch file resides at the first line of your batch file and see if it resolves the issue.
cd D:\wherever\yourBatch\fileIs
TIP: please use absolute paths, relative paths ideally should not be an issue, but scheduler has an difficult time understanding them.
Sure, use the .format method. E.g.,
print('{:10s} {:3d} {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d} {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d} {:7.2f}'.format('zz', 42, 123.34))
will print
xxx 123 98.00
yyyy 3 1.00
zz 42 123.34
You can adjust the field sizes as desired. Note that .format
works independently of print
to format a string. I just used print to display the strings. Brief explanation:
10s
format a string with 10 spaces, left justified by default
3d
format an integer reserving 3 spaces, right justified by default
7.2f
format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.
There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.
Update for f-string mode. E.g.,
text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d} {other_number:7.2f}')
For right alignment
print(f'{text:>10} {number:3d} {other_number:7.2f}')
Tensorflow 2.0 Compatible Answer: The explanations of dga
and stackoverflowuser2010
are very detailed about Logits and the related Functions.
All those functions, when used in Tensorflow 1.x
will work fine, but if you migrate your code from 1.x (1.14, 1.15, etc)
to 2.x (2.0, 2.1, etc..)
, using those functions result in error.
Hence, specifying the 2.0 Compatible Calls for all the functions, we discussed above, if we migrate from 1.x to 2.x
, for the benefit of the community.
Functions in 1.x:
tf.nn.softmax
tf.nn.softmax_cross_entropy_with_logits
tf.nn.sparse_softmax_cross_entropy_with_logits
Respective Functions when Migrated from 1.x to 2.x:
tf.compat.v2.nn.softmax
tf.compat.v2.nn.softmax_cross_entropy_with_logits
tf.compat.v2.nn.sparse_softmax_cross_entropy_with_logits
For more information about migration from 1.x to 2.x, please refer this Migration Guide.
Use filter
, or if the number of dictionaries in exampleSet
is too high, use ifilter
of the itertools
module. It would return an iterator, instead of filling up your system's memory with the entire list at once:
from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
print elem
Had a similar need. $compile
does the job. (Not completely sure if this is "THE" way to do it, still working my way through angular)
http://jsbin.com/ebuhuv/7/edit - my exploration test.
One thing to note (per my example), one of my requirements was that the template would change based on a type
attribute once you clicked save, and the templates were very different. So though, you get the data binding, if need a new template in there, you will have to recompile.
In addition to NateW's answer, if you have hyphens in your css class name, you should wrap that class within (single) quotes:
<th
class="initial "
v-on:click="myFilter"
v-bind:class="{ 'is-active' : isActive}"
>
<span class="wkday">M</span>
</th>

Sure, this can be done using profiles. You can do something like the following in your parent pom.xml.
...
<modules>
<module>module1</module>
<module>module2</module>
...
</modules>
...
<profiles>
<profile>
<id>ci</id>
<modules>
<module>module1</module>
<module>module2</module>
...
<module>module-integration-test</module>
</modules>
</profile>
</profiles>
...
In your CI, you would run maven with the ci
profile, i.e. mvn -P ci clean install
Some examples of formatted output to stdout and stderr:
printf("%s", "Hello world\n"); // "Hello world" on stdout (using printf)
fprintf(stdout, "%s", "Hello world\n"); // "Hello world" on stdout (using fprintf)
fprintf(stderr, "%s", "Stack overflow!\n"); // Error message on stderr (using fprintf)
I hadn't postgresql installed, so I just installed it using
sudo apt-get install postgresql postgresql-server-dev-9.1

This solved it.
Update:

How can I disable the cache temporarily or refresh the page in some way that I could see the changes?
It's unclear which "cache" you're referring to. There are several different methods a browser can cache content persistently. Web Storage being one of them, Cache-Control
being another.
Some browsers also have a Cache
, used in conjunction with Service Workers, to create Progressive Web Apps (PWAs) providing offline support.
To clear the cache for a PWA
self.caches.keys().then(keys => { keys.forEach(key => console.log(key)) })
to list the names of the cache keys, then run:
self.caches.delete('my-site-cache')
to delete a cache key by name (i.e., my-site-cache
). Then refresh the page.
If you see any worker-related errors in the console after refreshing, you may also need to unregister the registered workers:
navigator.serviceWorker.getRegistrations()
.then(registrations => {
registrations.forEach(registration => {
registration.unregister()
})
})
Disclamer: This is just a wild guess
I know everybody loves an easy-to-read list:
toBe(<value>)
- The returned value is the same as <value>
toBeTrue()
- Checks if the returned value is true
toBeTruthy()
- Check if the value, when cast to a boolean, will be a truthy value
Truthy values are all values that aren't 0
, ''
(empty string), false
, null
, NaN
, undefined
or []
(empty array)*.
* Notice that when you run !![]
, it returns true
, but when you run [] == false
it also returns true
. It depends on how it is implemented. In other words: (!![]) === ([] == false)
On your example, toBe(true)
and toBeTrue()
will yield the same results.

You just need to make the siprimo and volteado methods static.
private static bool siprimo(long a)
and
private static long volteado(long a)
for a 2 GB max limit, on your application web.config:
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" maxRequestLength="2147483647" executionTimeout="1600" requestLengthDiskThreshold="2147483647" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" />
</requestFiltering>
</security>
</system.webServer>
How about str.split()? Nothing to import.
import os
image_names = [f for f in os.listdir(path) if len(f.split('.jpg')) == 2]
JS
Create an external JavaScript file (i.e. mymap.js) with the following code
google.maps.visualRefresh = true; //Optional
var respMap;
function mymapini() {
var mapPos = new google.maps.LatLng(-0.172175,1.5); //Set the coordinates
var mapOpts = {
zoom: 10, //You can change this according your needs
disableDefaultUI: true, //Disabling UI Controls (Optional)
center: mapPos, //Center the map according coordinates
mapTypeId: google.maps.MapTypeId.ROADMAP
};
respMap = new google.maps.Map(document.getElementById('mymap'),
mapOpts);
var mapMarker = new google.maps.Marker({
position: mapPos,
map: respMap,
title: 'You can put any title'
});
//This centers automatically to the marker even if you resize your window
google.maps.event.addListener(respMap, 'idle', function() {
window.setTimeout(function() {
respMap.panTo(mapPos.getPosition());
}, 250);
});
}
google.maps.event.addDomListener(window, 'load', mymapini);
$("#modalOpen").click(function(){ //Use it like <a href="#" id="modalOpen"...
$("#myModal").show(); //ID from the Modal <div id="myModal">...
google.maps.event.trigger(respMap, 'resize');
});
HTML
Add the following code before the tag:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script src="js/mymap.js"></script>
Add this to the modal code:
<div id="mymap"></div>
CSS
Add this to your stylesheet:
#mymap { margin: 0; padding: 0; width:100%; height: 400px;}
With the user.language
, user.country
and user.variant
properties.
Example:
java -Duser.language=th -Duser.country=TH -Duser.variant=TH SomeClass
println
and print
are the two overloaded methods which belong to the PrintStream
class.
To access them we need an instance of this class.
A static property called out
of type PrintStream
is created on the System
class.
Hence to access the above methods we use the following statements:
System.out.println("foo");
System.out.print("foo");
To check column exists
select column_name as found
from user_tab_cols
where table_name = '__TABLE_NAME__'
and column_name = '__COLUMN_NAME__'
In my case I had a Kotlin class with some fields which were not open so the generated Java
setters and getters would be final. Solved it by adding open
keyword to each field.
Before:
open class User(
var id: String = "",
var email: String = ""
)
After:
open class User(
open var id: String = "",
open var email: String = ""
)
I tried removing the dataType row and it didn't work for me. I got around the issue by using "complete" instead of "success" as the callback. The success callback still fails in IE, but since my script runs and completes anyway that's all I care about.
$.ajax({
type: 'POST',
url: 'somescript.php',
data: someData,
complete: function(jqXHR) {
if(jqXHR.readyState === 4) {
... run some code ...
}
}
});
in jQuery 1.5 you can also do it like this.
var ajax = $.ajax({
type: 'POST',
url: 'somescript.php',
data: 'someData'
});
ajax.complete(function(jqXHR){
if(jqXHR.readyState === 4) {
... run some code ...
}
});
please try following to generate
function addRow()
{
var e1 = document.createElement("input");
e1.type = "text";
e1.name = "name1";
var cont = document.getElementById("content")
cont.appendChild(e1);
}
I started Task Manager, made sure adb.exe is closed (it locks some files)
Create the folder C:\Android Moved folder + all files from C:\Program Files\android-sdk to C:\Android
Edited C:\Documents and Settings\All Users\Start Menu\Programs\Android SDK Tools shortcuts.
I considered uninstalling the SDK and re-installing, but for the life of me, where does it store the temp files?? I don't
want to re-download the platforms, samples and doco that I have added to the SDK.
It work for me
$request = new Request();
$request->headers->set('content-type', 'application/json');
$request->initialize(['yourParam' => 2]);
check output
$queryParams = $request->query();
dd($queryParams['yourParam']); // 2
Just like it sounds like: if the path exists, but is a file and not a directory, isdir
will return False
. Meanwhile, exists
will return True
in both cases.
Programmatically, you can do this:
btn.BorderBrush = new SolidColorBrush(Colors.Transparent);
The Elvis (?.) Optional Chaining Operator is supported in TypeScript 3.7.
You can use it to check for null values: cats?.miows
returns null if cats is null or undefined.
You can also use it for optional method calling: cats.doMiow?.(5)
will call doMiow if it exists.
Property access is also possible: cats?.['miows']
.

This works, as long as you remove the height attribute from the table.
<table id="content" border="0px" cellspacing="0px" cellpadding="0px">
<tr><td height='9px' bgcolor="#990000">Upper</td></tr>
<tr><td height='100px' bgcolor="#990099">Lower</td></tr>
</table>
I'd wonder why someone would try to "override" the container width, since its purpose is to keep its content with some padding, but I had a similar situation (that's why I wanted to share my solution, even though there're answers).
In my situation, I wanted to have all content (of all pages) rendered inside a container, so this was the piece of code from my _Layout.cshtml:
<div id="body">
@RenderSection("featured", required: false)
<section class="content-wrapper main-content clear-fix">
<div class="container">
@RenderBody()
</div>
</section>
</div>
In my Home Index page, I had a background header image I'd like to fill the whole screen width, so the solution was to make the Index.cshtml like this:
@section featured {
<!-- This content will be rendered outside the "container div" -->
<div class="intro-header">
<div class="container">SOME CONTENT WITH A NICE BACKGROUND</div>
</div>
}
<!-- The content below will be rendered INSIDE the "container div" -->
<div class="content-section-b">
<div class="container">
<div class="row">
MORE CONTENT
</div>
</div>
</div>
I think this is better than trying to make workarounds, since sections are made with the purpose of allowing (or forcing) views to dynamically replace some content in the layout.
A good approach is to use a mixin to control stroke colour and fill colour. My svgs are used as icons.
@mixin icon($color, $hoverColor) {
svg {
fill: $color;
circle, line, path {
fill: $color
}
&:hover {
fill: $hoverColor;
circle, line, path {
fill: $hoverColor;
}
}
}
}
You can then do the following in your scss:
.container {
@include icon(white, blue);
}
(^|\s)
would match space or start of string and ($|\s)
for space or end of string. Together it's:
(^|\s)stackoverflow($|\s)
I know this is an old issue but I just had to do this for a project at work, and I am very surprised that nobody has thought of this solution yet: Just open the .pdf with Microsoft word.
The code is a lot easier to work with when you are trying to extract data from a .docx because it opens in Microsoft Word. Excel and Word play well together because they are both Microsoft programs. In my case, the file of question had to be a .pdf file. Here's the solution I came up with:
Yes you could just convert the .pdf file to a .docx file but this is a much simpler solution in my opinion.
Just for the record in history!
I've come up with a solution for my own work from 5-6 years ago, which is Gradext ( pure javascript and pure css, no dependency ) .
The technical explanation is you can create an element like this:
<span>A</span>
now if you want to make a gradient on text, you need to create some multiple layers, each individually specifically colored and the spectrum created will illustrate the gradient effect.
for example look at this is the word lorem inside of a <span>
and will cause a horizontal gradient effect ( check the examples ):
<span data-i="0" style="color: rgb(153, 51, 34);">L</span>
<span data-i="1" style="color: rgb(154, 52, 35);">o</span>
<span data-i="2" style="color: rgb(155, 53, 36);">r</span>
<span data-i="3" style="color: rgb(156, 55, 38);">e</span>
<span data-i="4" style="color: rgb(157, 56, 39);">m</span>
and you can continue doing this pattern for a long time and long paragraph as well.
What if you want to create a vertical gradient effect on texts?
Then there's another solution which could be helpful. I will describe in details.
Assuming our first <span>
again. but the content shouldn't be the letters individually; the content should be the whole text, and now we're going to copy the same ??<span>
again and again ( count of spans will define the quality of your gradient, more span, better result, but poor performance ). have a look at this:
<span data-i="6" style="color: rgb(81, 165, 39); overflow: hidden; height: 11.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="7" style="color: rgb(89, 174, 48); overflow: hidden; height: 12.8px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="8" style="color: rgb(97, 183, 58); overflow: hidden; height: 14.4px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="9" style="color: rgb(105, 192, 68); overflow: hidden; height: 16px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="10" style="color: rgb(113, 201, 78); overflow: hidden; height: 17.6px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="11" style="color: rgb(121, 210, 88); overflow: hidden; height: 19.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
what if you want to make these gradient effects to move and create an animation out of it?
well, there's another solution for it too. You should definitely check animation: true
or even .hoverable()
method which will lead to a gradient to start based on cursor position! ( sounds cool xD )
this is simply how we're creating gradients ( linear or radial ) on texts. If you liked the idea or want to know more about it, you should check the links provided.
Maybe this is not the best option, maybe not the best performant way to do this, but it will open up some space to create exciting and delightful animations to inspire some other people for a better solution.
It will allow you to use gradient style on texts, which is supported by even IE8!
Here you can find a working live demo and the original repository is here on GitHub as well, open source and ready to get some updates ( :D )
This is my first time ( yeah, after 5 years, you've heard it right ) to mention this repository anywhere on the Internet, and I'm excited about that!
[Update - 2019 August:] Github removed github-pages demo of that repository because I'm from Iran! Only the source code is available here tho...
if you want include Id
async getMarkers() {
const events = await firebase.firestore().collection('events')
events.get().then((querySnapshot) => {
const tempDoc = querySnapshot.docs.map((doc) => {
return { id: doc.id, ...doc.data() }
})
console.log(tempDoc)
})
}
Same way with array
async getMarkers() {
const events = await firebase.firestore().collection('events')
events.get().then((querySnapshot) => {
const tempDoc = []
querySnapshot.forEach((doc) => {
tempDoc.push({ id: doc.id, ...doc.data() })
})
console.log(tempDoc)
})
}
Yes, use the commercial but inexpensive SSMS Tools Pack addin which has a nifty "Generate Insert statements from resultsets, tables or database" feature
Thanks for the suggestions in the comments. I made a bit of a dirty hack to get what I want without having to create my own image. With javascript I first hide the default tag that's being used for the down arrow, like so:
$('b[role="presentation"]').hide();
I then included font-awesome in my page and add my own down arrow, again with a line of javascript, to replace the default one:
$('.select2-arrow').append('<i class="fa fa-angle-down"></i>');
Then with CSS I style the select boxes. I set the height, change the background color of the arrow area to a gradient black, change the width, font-size and also the color of the down arrow to white:
.select2-container .select2-choice {
padding: 5px 10px;
height: 40px;
width: 132px;
font-size: 1.2em;
}
.select2-container .select2-choice .select2-arrow {
background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
background-image: -moz-linear-gradient(top, #424242, #030303);
background-image: -ms-linear-gradient(top, #424242, #030303);
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
background-image: -webkit-linear-gradient(top, #424242, #030303);
background-image: -o-linear-gradient(top, #424242, #030303);
background-image: linear-gradient(#424242, #030303);
width: 40px;
color: #fff;
font-size: 1.3em;
padding: 4px 12px;
}
The result is the styling the way I want it:
Update 5/6/2015 As @Katie Lacy mentioned in the other answer the classnames have been changed in version 4 of Select2. The updated CSS with the new classnames should look like this:
.select2-container--default .select2-selection--single{
padding:6px;
height: 37px;
width: 148px;
font-size: 1.2em;
position: relative;
}
.select2-container--default .select2-selection--single .select2-selection__arrow {
background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
background-image: -moz-linear-gradient(top, #424242, #030303);
background-image: -ms-linear-gradient(top, #424242, #030303);
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
background-image: -webkit-linear-gradient(top, #424242, #030303);
background-image: -o-linear-gradient(top, #424242, #030303);
background-image: linear-gradient(#424242, #030303);
width: 40px;
color: #fff;
font-size: 1.3em;
padding: 4px 12px;
height: 27px;
position: absolute;
top: 0px;
right: 0px;
width: 20px;
}
JS:
$('b[role="presentation"]').hide();
$('.select2-selection__arrow').append('<i class="fa fa-angle-down"></i>');
Try using this library: https://github.com/jakiestfu/Blur.js-II
That should do it for ya.
Just for the sake of completeness, here is a solution with lambda and method reference:
Description: The following method
String
with the pattern yyyy-MM-dd
into a Timestamp
, if a valid input is given,null
, if a null
value is given,DateTimeParseException
, if an invalid input is givenCode:
static Timestamp convertStringToTimestamp(String strDate) {
return Optional.ofNullable(strDate) // wrap the String into an Optional
.map(str -> LocalDate.parse(str).atStartOfDay()) // convert into a LocalDate and fix the hour:minute:sec to 00:00:00
.map(Timestamp::valueOf) // convert to Timestamp
.orElse(null); // if no value is present, return null
}
Validation:
This method can be tested with those unit tests:
(with Junit5 and Hamcrest)
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenValidInput() {
// given
String strDate = "2020-01-30";
// when
final Timestamp result = convertStringToTimestamp(strDate);
// then
final LocalDateTime dateTime = LocalDateTime.ofInstant(result.toInstant(), ZoneId.systemDefault());
assertThat(dateTime.getYear(), is(2020));
assertThat(dateTime.getMonthValue(), is(1));
assertThat(dateTime.getDayOfMonth(), is(30));
}
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenInvalidInput() {
// given
String strDate = "7770-91-30";
// when, then
assertThrows(DateTimeParseException.class, () -> convertStringToTimestamp(strDate));
}
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenNullInput() {
// when
final Timestamp result = convertStringToTimestamp(null);
// then
assertThat(result, is(nullValue()));
}
Usually, the string to parse comes with another format. A way to deal with it is to use a formatter to convert it to another format. Here is an example:
Input: 20200130 11:30
Pattern: yyyyMMdd HH:mm
Output: Timestamp of this input
Code:
static Timestamp convertStringToTimestamp(String strDate) {
final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm");
return Optional.ofNullable(strDate) //
.map(str -> LocalDateTime.parse(str, formatter))
.map(Timestamp::valueOf) //
.orElse(null);
}
Test:
@Test
void convertStringToTimestamp_shouldReturnTimestamp_whenValidInput() {
// given
String strDate = "20200130 11:30";
// when
final Timestamp result = convertStringToTimestamp(strDate);
// then
final LocalDateTime dateTime = LocalDateTime.ofInstant(result.toInstant(), ZoneId.systemDefault());
assertThat(dateTime.getYear(), is(2020));
assertThat(dateTime.getMonthValue(), is(1));
assertThat(dateTime.getDayOfMonth(), is(30));
assertThat(dateTime.getHour(), is(11));
assertThat(dateTime.getMinute(), is(30));
}
For those who don't care about breaking compatibility with PHP < 5.4
, I'd suggest using type hinting to make a cleaner implementation.
function call_with_hello_and_append_world( callable $callback )
{
// No need to check $closure because of the type hint
return $callback( "hello" )."world";
}
function append_space( $string )
{
return $string." ";
}
$output1 = call_with_hello_and_append_world( function( $string ) { return $string." "; } );
var_dump( $output1 ); // string(11) "hello world"
$output2 = call_with_hello_and_append_world( "append_space" );
var_dump( $output2 ); // string(11) "hello world"
$old_lambda = create_function( '$string', 'return $string." ";' );
$output3 = call_with_hello_and_append_world( $old_lambda );
var_dump( $output3 ); // string(11) "hello world"
it seems
command args overwrite environment variable
Makefile
send:
echo $(MESSAGE1) $(MESSAGE2)
Run example
$ MESSAGE1=YES MESSAGE2=NG make send MESSAGE2=OK
echo YES OK
YES OK

INSERT INTO tab_student (name_student, id_teacher_fk)
VALUES ('dan red',
(SELECT id_teacher FROM tab_teacher WHERE name_teacher ='jason bourne')
it is advisable to store your values in lowercase to make retrieval easier and less error prone
INSERT INTO tab_teacher (name_teacher)
VALUES ('tom stills')
INSERT INTO tab_student (name_student, id_teacher_fk)
VALUES ('rich man', LAST_INSERT_ID())
Instead of using the ScrimInsetsFrameLayout
... Isn't it easier to just add a view with a fixed height of 24dp
and a background of primaryColor
?
I understand that this involves adding a dummy view in the hierarchy, but it seems cleaner to me.
I already tried it and it's working well.

If you are using jQuery you can do something like this
$('label[for="foo"]').hide ();
If you aren't using jQuery you'll have to search for the label. Here is a function that takes the element as an argument and returns the associated label
function findLableForControl(el) {
var idVal = el.id;
labels = document.getElementsByTagName('label');
for( var i = 0; i < labels.length; i++ ) {
if (labels[i].htmlFor == idVal)
return labels[i];
}
}
With dplyr
and stringr
you can use mutate_all
:
> df %>% mutate_all(funs(length = str_length(.)))
col1 col2 col1_length col2_length
1 abc adf qqwe 3 8
2 abcd d 4 1
3 a e 1 1
4 abcdefg f 7 1
To test the error handling, you can do something like this:
feature ErrorHandling do
before do
Rails.application.config.consider_all_requests_local = false
Rails.application.config.action_dispatch.show_exceptions = true
end
scenario 'renders not_found template' do
visit '/blah'
expect(page).to have_content "The page you were looking for doesn't exist."
end
end
You can also start a server without python using php interpreter.
E.g:
cd /your/path/to/website/root
php -S localhost:8000
This can be useful if you want an alternative to npm, as php utility comes preinstalled on some OS' (including Mac).
PackageInfo pinfo = this.getPackageManager().getPackageInfo(getPackageName(), 0);
String sVersionCode = pinfo.versionCode; // 1
String sVersionName = pinfo.versionName; // 1.0
String sPackName = getPackageName(); // cz.okhelp.my_app
int nSdkVersion = Integer.parseInt(Build.VERSION.SDK);
int nSdkVers = Build.VERSION.SDK_INT;
Hope it will work.
Position the outer div however you want, then position the inner divs using absolute. They'll all stack up.
.inner {_x000D_
position: absolute;_x000D_
}
_x000D_
<div class="outer">_x000D_
<div class="inner">1</div>_x000D_
<div class="inner">2</div>_x000D_
<div class="inner">3</div>_x000D_
<div class="inner">4</div>_x000D_
</div>
_x000D_
I use RStudio or Emacs and always use the editor shortcuts available to comment regions. If this is not a possibility then you could use Paul's answer but this only works if your code is syntactically correct.
Here is another dirty way I came up with, wrap it in scan()
and remove the result. It does store the comment in memory for a short while so it will probably not work with very large comments. Best still is to just put #
signs in front of every line (possibly with editor shortcuts).
foo <- scan(what="character")
These are comments
These are still comments
Can also be code:
x <- 1:10
One line must be blank
rm(foo)
I came up with a pretty naive solution, but it seems to work. My goal was to prevent accidental double-taps to be interpreted as zoom in, while keeping pinch to zoom working for accessibility.
The idea is in measuring time between the first touchstart
and second touchend
in a double tap and then interpreting the last touchend
as click if the delay is too small. While preventing accidental zooming, this method seems to keep list scrolling unaffected, which is nice. Not sure if I haven't missed anything though.
let preLastTouchStartAt = 0;
let lastTouchStartAt = 0;
const delay = 500;
document.addEventListener('touchstart', () => {
preLastTouchStartAt = lastTouchStartAt;
lastTouchStartAt = +new Date();
});
document.addEventListener('touchend', (event) => {
const touchEndAt = +new Date();
if (touchEndAt - preLastTouchStartAt < delay) {
event.preventDefault();
event.target.click();
}
});
Inspired by a gist from mutewinter and Joseph's answer.
You can use .change()
$('input[name=myInput]').change(function() { ... });
However, this event will only fire when the selector has lost focus, so you will need to click somewhere else to have this work.
If that's not quite right for you, you could use some of the other jQuery events like keyup, keydown or keypress - depending on the exact effect you want.
Wrote a quick TDD Test for this
[TestMethod]
public void Test()
{
var input = @"ProjectName\Iteration\Release1\Iteration1";
var pattern = @"\\Iteration";
var rgx = new Regex(pattern);
var result = rgx.Replace(input, "", 1);
Assert.IsTrue(result.Equals(@"ProjectName\Release1\Iteration1"));
}
rgx.Replace(input, "", 1); says to look in input for anything matching the pattern, with "", 1 time.
Working example
@Repository
public interface TenantRepository extends JpaRepository< Tenant, Long > {
List<Tenant>findByTenantName(String tenantName,Pageable pageRequest);
long countByTenantName(String tenantName);
}
Calling from DAO layer
@Override
public long countByTenantName(String tenantName) {
return repository.countByTenantName(tenantName);
}
Should not enclose true with double quote " " it should be like
$(document).ready(function() {
$('input').attr('required', true);
});
Also you can use prop
jQuery(document).ready(function() {
$('input').prop('required', true);
});
Instead of true you can try required. Such as
$('input').prop('required', 'required');
Here is the directive I use. It automatically cleans itself up when the form is unloaded. If you want to prevent the prompt from firing (e.g. because you successfully saved the form), call $scope.FORMNAME.$setPristine(), where FORMNAME is the name of the form you want to prevent from prompting.
.directive('dirtyTracking', [function () {
return {
restrict: 'A',
link: function ($scope, $element, $attrs) {
function isDirty() {
var formObj = $scope[$element.attr('name')];
return formObj && formObj.$pristine === false;
}
function areYouSurePrompt() {
if (isDirty()) {
return 'You have unsaved changes. Are you sure you want to leave this page?';
}
}
window.addEventListener('beforeunload', areYouSurePrompt);
$element.bind("$destroy", function () {
window.removeEventListener('beforeunload', areYouSurePrompt);
});
$scope.$on('$locationChangeStart', function (event) {
var prompt = areYouSurePrompt();
if (!event.defaultPrevented && prompt && !confirm(prompt)) {
event.preventDefault();
}
});
}
};
}]);
As Jonathan Leaders mentioned here, it is important to run the command/script elevated to be able to change environment variables for 'machine', but running some commands elevated doesn't have to be done with the Community Extensions, so I'd like to modify and extend JeanT's answer in a way, that changing machine variables also can be performed even if the script itself isn't run elevated:
function Set-Path ([string]$newPath, [bool]$permanent=$false, [bool]$forMachine=$false )
{
$Env:Path += ";$newPath"
$scope = if ($forMachine) { 'Machine' } else { 'User' }
if ($permanent)
{
$command = "[Environment]::SetEnvironmentVariable('PATH', $env:Path, $scope)"
Start-Process -FilePath powershell.exe -ArgumentList "-noprofile -command $Command" -Verb runas
}
}
If any body wants to convert list of custom class objects instead of list of string then override the ToString method of your class with csv row representation of your class.
Public Class MyClass{
public int Id{get;set;}
public String PropertyA{get;set;}
public override string ToString()
{
return this.Id+ "," + this.PropertyA;
}
}
Then following code can be used to convert this class list to CSV with header column
string csvHeaderRow = String.Join(",", typeof(MyClass).GetProperties(BindingFlags.Public | BindingFlags.Instance).Select(x => x.Name).ToArray<string>()) + Environment.NewLine;
string csv= csvHeaderRow + String.Join(Environment.NewLine, MyClass.Select(x => x.ToString()).ToArray());
Several answers show dangerous examples. OP's example [ $a == $b ]
specifically used unquoted variable substitution (as of Oct '17 edit). For [...]
that is safe for string equality.
But if you're going to enumerate alternatives like [[...]]
, you must inform also that the right-hand-side must be quoted. If not quoted, it is a pattern match! (From bash man page: "Any part of the pattern may be quoted to force it to be matched as a string.").
Here in bash, the two statements yielding "yes" are pattern matching, other three are string equality:
$ rht="A*"
$ lft="AB"
$ [ $lft = $rht ] && echo yes
$ [ $lft == $rht ] && echo yes
$ [[ $lft = $rht ]] && echo yes
yes
$ [[ $lft == $rht ]] && echo yes
yes
$ [[ $lft == "$rht" ]] && echo yes
$
Or you can use temporary array and then delete the real one if you want to change it while in cycle:
$array = array(0 => 'a', 1 => 'b', 2 => 'c');
$temp_array = $array[1];
unset($array[1]);
array_unshift($array , $temp_array);
the output will be:
array(0 => 'b', 1 => 'a', 2 => 'c')
and when are doing it while in cycle, you should clean $temp_array
after appending item to array.
