A quick way to do it in sql server 2012 is as follows:
SELECT FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss')
Imo, the best way to parse your JSON response with GSON would be creating classes that "match" your response and then use Gson.fromJson()
method.
For example:
class Response {
Map<String, App> descriptor;
// standard getters & setters...
}
class App {
String name;
int age;
String[] messages;
// standard getters & setters...
}
Then just use:
Gson gson = new Gson();
Response response = gson.fromJson(yourJson, Response.class);
Where yourJson
can be a String
, any Reader
, a JsonReader
or a JsonElement
.
Finally, if you want to access any particular field, you just have to do:
String name = response.getDescriptor().get("app3").getName();
You can always parse the JSON manually as suggested in other answers, but personally I think this approach is clearer, more maintainable in long term and it fits better with the whole idea of JSON.
Upcoming pandas 0.13 version will allow to add rows through loc
on non existing index data. However, be aware that under the hood, this creates a copy of the entire DataFrame so it is not an efficient operation.
Description is here and this new feature is called Setting With Enlargement.
Have you tried loading all the initialization functions using the $().ready
, running the jQuery function you wanted last?
Perhaps you can use setTimeout()
on the $().ready
function you wanted to run, calling the functionality you wanted to load.
Or, use setInterval()
and have the interval check to see if all the other load functions have completed (store the status in a boolean variable). When conditions are met, you could cancel the interval and run the load function.
The most common mistake (especially when using express) to the "my insert didn't happen" is : looking in the wrong file.
If you are using file-based express (rather than strongly attached), then the file in your project folder (say, c:\dev\myproject\mydb.mbd
) is not the file that is used in your program. When you build, that file is copied - for example to c:\dev\myproject\bin\debug\mydb.mbd
; your program executes in the context of c:\dev\myproject\bin\debug\
, and so it is here that you need to look to see if the edit actually happened. To check for sure: query for the data inside the application (after inserting it).
Since you're using PHP, you will probably need to use the CURLOPT_PORT
option, like so:
curl_setopt($ch, CURLOPT_PORT, 11740);
Bear in mind, you may face problems with SELinux:
In my case 'await' never finished because of exception while executing the request, e.g. server not responding, etc. Surround it with try..catch to identify what happened, it'll also complete your 'await' gracefully.
public async Task<Stuff> GetStuff(string id)
{
string path = $"/api/v2/stuff/{id}";
try
{
HttpResponseMessage response = await client.GetAsync(path);
if (response.StatusCode == HttpStatusCode.OK)
{
string json = await response.Content.ReadAsStringAsync();
return JsonUtility.FromJson<Stuff>(json);
}
else
{
Debug.LogError($"Could not retrieve stuff {id}");
}
}
catch (Exception exception)
{
Debug.LogError($"Exception when retrieving stuff {exception}");
}
return null;
}
You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.
The string representation of a float doesn't work this way. For example, repr(1.3)
yields '1.3'
, but repr(1.33)
yields '1.3300000000000001'
.
A accurate string representation of a floating point number produces a variable length string.
Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.
If you use x.astype('str')
, it will always convert things to an array of strings of length 1.
For example, using x = np.array(1.344566)
, x.astype('str')
yields '1'
!
You need to be more explict and use the '|Sx'
dtype syntax, where x
is the length of the string for each element of the array.
For example, use x.astype('|S10')
to convert the array to strings of length 10.
Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...
In my case, I had generated DbContext from an existing database. I had my connection string set in appSettings.json
file; however, when I generated the class files by scaffolding the DbContext class it had incorrect connection string.
So make sure your connection string is proper in appSettings.json
file as well as in DbContext
file. This will solve your issue.
This error can be due to many many things.
The key here seems the hint about error reading
. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.
You could also try with sudo
, that might solve a permission problem if that's the case.
Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...
I found the following example from the docs really helpful (source here).
package main
import (
"encoding/json"
"fmt"
"io"
"log"
"strings"
)
func main() {
const jsonStream = `
{"Name": "Ed", "Text": "Knock knock."}
{"Name": "Sam", "Text": "Who's there?"}
{"Name": "Ed", "Text": "Go fmt."}
{"Name": "Sam", "Text": "Go fmt who?"}
{"Name": "Ed", "Text": "Go fmt yourself!"}
`
type Message struct {
Name, Text string
}
dec := json.NewDecoder(strings.NewReader(jsonStream))
for {
var m Message
if err := dec.Decode(&m); err == io.EOF {
break
} else if err != nil {
log.Fatal(err)
}
fmt.Printf("%s: %s\n", m.Name, m.Text)
}
}
The key here being that the OP was looking to decode
type test_struct struct {
Test string
}
...in which case we would drop the const jsonStream
, and replace the Message
struct with the test_struct
:
func test(rw http.ResponseWriter, req *http.Request) {
dec := json.NewDecoder(req.Body)
for {
var t test_struct
if err := dec.Decode(&t); err == io.EOF {
break
} else if err != nil {
log.Fatal(err)
}
log.Printf("%s\n", t.Test)
}
}
Update: I would also add that this post provides some great data about responding with JSON as well. The author explains struct tags
, which I was not aware of.
Since JSON does not normally look like {"Test": "test", "SomeKey": "SomeVal"}
, but rather {"test": "test", "somekey": "some value"}
, you can restructure your struct like this:
type test_struct struct {
Test string `json:"test"`
SomeKey string `json:"some-key"`
}
...and now your handler will parse JSON using "some-key" as opposed to "SomeKey" (which you will be using internally).
Path Variables dialog has nothing to do with the environment variables.
Environment variables can be specified in your OS or customized in the Run configuration:
From What's this "serialization" thing all about?:
It lets you take an object or group of objects, put them on a disk or send them through a wire or wireless transport mechanism, then later, perhaps on another computer, reverse the process: resurrect the original object(s). The basic mechanisms are to flatten object(s) into a one-dimensional stream of bits, and to turn that stream of bits back into the original object(s).
Like the Transporter on Star Trek, it's all about taking something complicated and turning it into a flat sequence of 1s and 0s, then taking that sequence of 1s and 0s (possibly at another place, possibly at another time) and reconstructing the original complicated "something."
So, implement the Serializable
interface when you need to store a copy of the object, send them to another process which runs on the same system or over the network.
Because you want to store or send an object.
It makes storing and sending objects easy. It has nothing to do with security.
Ok, this was asked 7 years ago, but I think the best solution here is to forego the new table entirely and just do this as a custom view. That way you're not duplicating data, there's no worry about unique data, and it doesn't touch the actual database structure. Something like this:
CREATE VIEW vw_competitions
AS
SELECT
Id int
CompetitionName nvarchar(75)
CompetitionType nvarchar(50)
OtherField1 int
OtherField2 nvarchar(64) --add the fields you want viewed from the Competition table
FROM Competitions
GO
Other items can be added here like joins on other tables, WHERE clauses, etc. This is most likely the most elegant solution to this problem, as you now can just query the view:
SELECT *
FROM vw_competitions
...and add any WHERE, IN, or EXISTS clauses to the view query.
here's a hairy, built in way to get many of the same answers. Note that although python considers ""
to be false and all other strings to be true, TCL has a very different idea about things.
>>> import Tkinter
>>> tk = Tkinter.Tk()
>>> var = Tkinter.BooleanVar(tk)
>>> var.set("false")
>>> var.get()
False
>>> var.set("1")
>>> var.get()
True
>>> var.set("[exec 'rm -r /']")
>>> var.get()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/lib-tk/Tkinter.py", line 324, in get
return self._tk.getboolean(self._tk.globalgetvar(self._name))
_tkinter.TclError: 0expected boolean value but got "[exec 'rm -r /']"
>>>
A good thing about this is that it is fairly forgiving about the values you can use. It's lazy about turning strings into values, and it's hygenic about what it accepts and rejects(notice that if the above statement were given at a tcl prompt, it would erase the users hard disk).
the bad thing is that it requires that Tkinter be available, which is usually, but not universally true, and more significantly, requires that a Tk instance be created, which is comparatively heavy.
What is considered true or false depends on the behavior of the Tcl_GetBoolean
, which considers 0
, false
, no
and off
to be false and 1
, true
, yes
and on
to be true, case insensitive. Any other string, including the empty string, cause an exception.
Async functions, a feature in ES2017, make async code look sync by using promises (a particular form of async code) and the await
keyword. Also notice in the code examples below the keyword async
in front of the function
keyword that signifies an async/await function. The await
keyword won't work without being in a function pre-fixed with the async
keyword. Since currently there is no exception to this that means no top level awaits will work (top level awaits meaning an await outside of any function). Though there is a proposal for top-level await
.
ES2017 was ratified (i.e. finalized) as the standard for JavaScript on June 27th, 2017. Async await may already work in your browser, but if not you can still use the functionality using a javascript transpiler like babel or traceur. Chrome 55 has full support of async functions. So if you have a newer browser you may be able to try out the code below.
See kangax's es2017 compatibility table for browser compatibility.
Here's an example async await function called doAsync
which takes three one second pauses and prints the time difference after each pause from the start time:
function timeoutPromise (time) {_x000D_
return new Promise(function (resolve) {_x000D_
setTimeout(function () {_x000D_
resolve(Date.now());_x000D_
}, time)_x000D_
})_x000D_
}_x000D_
_x000D_
function doSomethingAsync () {_x000D_
return timeoutPromise(1000);_x000D_
}_x000D_
_x000D_
async function doAsync () {_x000D_
var start = Date.now(), time;_x000D_
console.log(0);_x000D_
time = await doSomethingAsync();_x000D_
console.log(time - start);_x000D_
time = await doSomethingAsync();_x000D_
console.log(time - start);_x000D_
time = await doSomethingAsync();_x000D_
console.log(time - start);_x000D_
}_x000D_
_x000D_
doAsync();
_x000D_
When the await keyword is placed before a promise value (in this case the promise value is the value returned by the function doSomethingAsync) the await keyword will pause execution of the function call, but it won't pause any other functions and it will continue executing other code until the promise resolves. After the promise resolves it will unwrap the value of the promise and you can think of the await and promise expression as now being replaced by that unwrapped value.
So, since await just pauses waits for then unwraps a value before executing the rest of the line you can use it in for loops and inside function calls like in the below example which collects time differences awaited in an array and prints out the array.
function timeoutPromise (time) {_x000D_
return new Promise(function (resolve) {_x000D_
setTimeout(function () {_x000D_
resolve(Date.now());_x000D_
}, time)_x000D_
})_x000D_
}_x000D_
_x000D_
function doSomethingAsync () {_x000D_
return timeoutPromise(1000);_x000D_
}_x000D_
_x000D_
// this calls each promise returning function one after the other_x000D_
async function doAsync () {_x000D_
var response = [];_x000D_
var start = Date.now();_x000D_
// each index is a promise returning function_x000D_
var promiseFuncs= [doSomethingAsync, doSomethingAsync, doSomethingAsync];_x000D_
for(var i = 0; i < promiseFuncs.length; ++i) {_x000D_
var promiseFunc = promiseFuncs[i];_x000D_
response.push(await promiseFunc() - start);_x000D_
console.log(response);_x000D_
}_x000D_
// do something with response which is an array of values that were from resolved promises._x000D_
return response_x000D_
}_x000D_
_x000D_
doAsync().then(function (response) {_x000D_
console.log(response)_x000D_
})
_x000D_
The async function itself returns a promise so you can use that as a promise with chaining like I do above or within another async await function.
The function above would wait for each response before sending another request if you would like to send the requests concurrently you can use Promise.all.
// no change_x000D_
function timeoutPromise (time) {_x000D_
return new Promise(function (resolve) {_x000D_
setTimeout(function () {_x000D_
resolve(Date.now());_x000D_
}, time)_x000D_
})_x000D_
}_x000D_
_x000D_
// no change_x000D_
function doSomethingAsync () {_x000D_
return timeoutPromise(1000);_x000D_
}_x000D_
_x000D_
// this function calls the async promise returning functions all at around the same time_x000D_
async function doAsync () {_x000D_
var start = Date.now();_x000D_
// we are now using promise all to await all promises to settle_x000D_
var responses = await Promise.all([doSomethingAsync(), doSomethingAsync(), doSomethingAsync()]);_x000D_
return responses.map(x=>x-start);_x000D_
}_x000D_
_x000D_
// no change_x000D_
doAsync().then(function (response) {_x000D_
console.log(response)_x000D_
})
_x000D_
If the promise possibly rejects you can wrap it in a try catch or skip the try catch and let the error propagate to the async/await functions catch call. You should be careful not to leave promise errors unhandled especially in Node.js. Below are some examples that show off how errors work.
function timeoutReject (time) {_x000D_
return new Promise(function (resolve, reject) {_x000D_
setTimeout(function () {_x000D_
reject(new Error("OOPS well you got an error at TIMESTAMP: " + Date.now()));_x000D_
}, time)_x000D_
})_x000D_
}_x000D_
_x000D_
function doErrorAsync () {_x000D_
return timeoutReject(1000);_x000D_
}_x000D_
_x000D_
var log = (...args)=>console.log(...args);_x000D_
var logErr = (...args)=>console.error(...args);_x000D_
_x000D_
async function unpropogatedError () {_x000D_
// promise is not awaited or returned so it does not propogate the error_x000D_
doErrorAsync();_x000D_
return "finished unpropogatedError successfully";_x000D_
}_x000D_
_x000D_
unpropogatedError().then(log).catch(logErr)_x000D_
_x000D_
async function handledError () {_x000D_
var start = Date.now();_x000D_
try {_x000D_
console.log((await doErrorAsync()) - start);_x000D_
console.log("past error");_x000D_
} catch (e) {_x000D_
console.log("in catch we handled the error");_x000D_
}_x000D_
_x000D_
return "finished handledError successfully";_x000D_
}_x000D_
_x000D_
handledError().then(log).catch(logErr)_x000D_
_x000D_
// example of how error propogates to chained catch method_x000D_
async function propogatedError () {_x000D_
var start = Date.now();_x000D_
var time = await doErrorAsync() - start;_x000D_
console.log(time - start);_x000D_
return "finished propogatedError successfully";_x000D_
}_x000D_
_x000D_
// this is what prints propogatedError's error._x000D_

If you go here you can see the finished proposals for upcoming ECMAScript versions.
An alternative to this that can be used with just ES2015 (ES6) is to use a special function which wraps a generator function. Generator functions have a yield keyword which may be used to replicate the await keyword with a surrounding function. The yield keyword and generator function are a lot more general purpose and can do many more things then just what the async await function does. If you want a generator function wrapper that can be used to replicate async await I would check out co.js. By the way co's function much like async await functions return a promise. Honestly though at this point browser compatibility is about the same for both generator functions and async functions so if you just want the async await functionality you should use Async functions without co.js.
Browser support is actually pretty good now for Async functions (as of 2017) in all major current browsers (Chrome, Safari, and Edge) except IE.
I had exactly the same requirement a while ago, and ended up solving it using APScheduler (User Guide)
It makes scheduling jobs super simple, and keeps it independent for from request-based execution of some code. Following is a simple example.
from apscheduler.schedulers.background import BackgroundScheduler
scheduler = BackgroundScheduler()
job = None
def tick():
print('One tick!')\
def start_job():
global job
job = scheduler.add_job(tick, 'interval', seconds=3600)
try:
scheduler.start()
except:
pass
Hope this helps somebody!

Simple and easy
I found the smoothest way to achieve this was using Pageant as the SSH agent and plink.
You need to have a putty session configured for the hostname that is used in your remote.
You will also need plink.exe which can be downloaded from the same site as putty.
And you need Pageant running with your key loaded. I have a shortcut to pageant in my startup folder that loads my SSH key when I log in.
When you install git-scm you can then specify it to use tortoise/plink rather than OpenSSH.
The net effect is you can open git-bash whenever you like and push/pull without being challenged for passphrases.
Same applies with putty and WinSCP sessions when pageant has your key loaded. It makes life a hell of a lot easier (and secure).
I use another Eclipse plugin to import existing gradle projects.
You can install the Builship Gradle Gntegration 2.0 using the Eclipse Marketplace client.
Then you choose FIle ? Import ? Existing Gradle Project.
Finially, indicate your project root directory and click finish.
That was my case. It actually links to question #4485874, but I'm going to explain it here shortly.
When you try to require path/to/script.php?parameter=value
, PHP looks for file named script.php?parameter=value
, because UNIX allows you to have paths like this.
If you are really need to pass some data to included script, just declare it as $variable=...
or $GLOBALS[]=...
or other way you like.

After testing several unreliable implementations, the algorithm that provided satisfactory results regarding the CW/CCW orientation out of the box was the one, posted by OP in this thread (shoelace_formula_3
).
As always, a positive number represents a CW orientation, whereas a negative number CCW.
We faced the same problem:

ORA-29400: data cartridge error error opening file /fs01/app/rms01/external/logs/SH_EXT_TAB_VGAG_DELIV_SCHED.log
In our case we had a RAC with 2 nodes. After giving write permission on the log directory, on both sides, everything worked fine.
I think you could experiment with different activity flags, as it sounds like multiple instances.
"singleTop" "singleTask" "singleInstance"
Are the ones I would try, they can be defined inside the manifest.
http://developer.android.com/guide/topics/manifest/activity-element.html
Use curly braces around the variable name:
`tail -1 ${filepath}_newstap.sh`
I faced the same problem and resolved it by creating a static class Parameters
after adding an Application Configuration File to the project:
public static class Parameters
{
// For a Web Application
public static string PathConfig { get; private set; } =
Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "web.config");
// For a Class Library
public static string PathConfig { get; private set; } =
Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin", "LibraryName.dll.config");
public static string GetParameter(string paramName)
{
string paramValue = string.Empty;
using (Stream stream = File.OpenRead(PathConfig))
{
XDocument xdoc = XDocument.Load(stream);
XElement element = xdoc.Element("configuration").Element("appSettings").Elements().First(a => a.Attribute("key").Value == paramName);
paramValue = element.Attribute("value").Value;
}
return paramValue;
}
}
Then get a parameter like this:
Parameters.GetParameter("keyName");
why dont you try something very simple?

Here's a one line example, that uses plain JavaScript to inject a CSS link into the head element based on the filename portion of the URL:
document.head.innerHTML += '<link rel="stylesheet" href="css/style.css">';
Most browsers support it. See the browser compatibility.
DEMO: http://jsfiddle.net/PBhHK/
$(document).ready(function(){
var searchIDs = $('input:checked').map(function(){
return $(this).val();
});
console.log(searchIDs.get());
});
Just call get() and you'll have your array as it is written in the specs: http://api.jquery.com/map/
$(':checkbox').map(function() {
return this.id;
}).get().join();
Yes, use DialogFragment
and in onCreateDialog
you can simply use an AlertDialog builder anyway to create a simple AlertDialog
with Yes/No confirmation buttons. Not very much code at all.
With regards handling events in your fragment there would be various ways of doing it but I simply define a message Handler
in my Fragment
, pass it into the DialogFragment
via its constructor and then pass messages back to my fragment's handler as approprirate on the various click events. Again various ways of doing that but the following works for me.
In the dialog hold a message and instantiate it in the constructor:
private Message okMessage;
...
okMessage = handler.obtainMessage(MY_MSG_WHAT, MY_MSG_OK);
Implement the onClickListener
in your dialog and then call the handler as appropriate:
public void onClick(.....
if (which == DialogInterface.BUTTON_POSITIVE) {
final Message toSend = Message.obtain(okMessage);
toSend.sendToTarget();
}
}
Edit
And as Message
is parcelable you can save it out in onSaveInstanceState
and restore it
outState.putParcelable("okMessage", okMessage);
Then in onCreate
if (savedInstanceState != null) {
okMessage = savedInstanceState.getParcelable("okMessage");
}

}
return c;
}
// Send data TO Database
public static void setData(String sql) throws Exception {
DB.getConnection().createStatement().executeUpdate(sql);
}
// Get Data From Database
public static ResultSet getData(String sql) throws Exception {
ResultSet rs = DB.getConnection().createStatement().executeQuery(sql);
return rs;
}
}
Inside the app/res/your_xml_layout_file.xml
I ran into a similar bind in a render function and ended up passing the context of this
in the following way:
{someList.map(function(listItem) {
// your code
}, this)}
I've also used:
{someList.map((listItem, index) =>
<div onClick={this.someFunction.bind(this, listItem)} />
)}
Your question is quite vague but I think this is what you need:
$(function() {
$('input[type="checkbox"]').bind('click',function() {
if($(this).is(':checked')) {
$('#some_textarea').html($(this).val());
}
});
});
Edit: Oh, okay.. there you go... You didn't have the HTML up before. Anyways, yeah, I thought you meant to put the value in a textarea when it gets clicked. If you want the checked checkboxes' values to be put into the textarea (maybe with a nice comma-seperation) on page load it would be as simple as:
$(function() {
$('#c_b input[type="checkbox"]:checked').each(function() {
$('#t').append(', '+$(this).val());
});
});
Edit 2 As people have done, you can also do this to shortcut the lengthy selector I wrote:
$('#c_b :checkbox:checked').each(function() {
$('#t').append(', '+$(this).val());
});
... I totally forgot about that shortcut. ;)
For static resources right caching would be to use query parameters with value of each deployment or file version. This will have effect of clearing cache after each deployment.

i called activity_name.this.finish()
after starting new intent and it worked for me.
I tried "FLAG_ACTIVITY_CLEAR_TOP" and "FLAG_ACTIVITY_NEW_TASK"
But it won't work for me... I am not suggesting this solution for use but if setting flag won't work for you than you can try this..But still i recommend don't use it

For what its worth, I have a SitesAPIController, and I needed a custom method, that could be called like:
http://localhost:9000/api/SitesAPI/Disposition/0
With different values for the last parameter to get record with different dispositions.
What Finally worked for me was:
The method in the SitesAPIController:
// GET api/SitesAPI/Disposition/1
[ActionName("Disposition")]
[HttpGet]
public Site Disposition(int disposition)
{
Site site = db.Sites.Where(s => s.Disposition == disposition).First();
return site;
}
And this in the WebApiConfig.cs
// this was already there
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
// this i added
config.Routes.MapHttpRoute(
name: "Action",
routeTemplate: "api/{controller}/{action}/{disposition}"
);
For as long as I was naming the {disposition} as {id} i was encountering:
{
"Message": "No HTTP resource was found that matches the request URI 'http://localhost:9000/api/SitesAPI/Disposition/0'.",
"MessageDetail": "No action was found on the controller 'SitesAPI' that matches the request."
}
When I renamed it to {disposition} it started working. So apparently the parameter name is matched with the value in the placeholder.

Starting with Spring Security version 3.2, the custom functionality that has been implemented by some of the older answers, exists out of the box in the form of the @AuthenticationPrincipal
annotation that is backed by AuthenticationPrincipalArgumentResolver
.
An simple example of it's use is:
@Controller
public class MyController {
@RequestMapping("/user/current/show")
public String show(@AuthenticationPrincipal CustomUser customUser) {
// do something with CustomUser
return "view";
}
}
CustomUser needs to be assignable from authentication.getPrincipal()
Here are the corresponding Javadocs of AuthenticationPrincipal and AuthenticationPrincipalArgumentResolver
Had the same issue a while ago, my problem was, I simply needed the base url. There are a lot of detailed options here but to get around this, simply use the window.location
object. Actually type this in the browser console and hit enter to select your options there. Well for my case it was simply:
window.location.origin
The warning message is because your "Type" variable was made a factor and "lunch" was not a defined level. Use the stringsAsFactors = FALSE
flag when making your data frame to force "Type" to be a character.

> str(fixed)
'data.frame': 3 obs. of 2 variables:
$ Type : Factor w/ 1 level "": NA 1 1

@fizzer.myopenid.com: your posted code snippet is equivalent to the following:

I definitely prefer this form.
Exported variables such as $HOME
and $PATH
are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.
$ env | grep '^variable='
$ # No environment variable called variable
$ variable=Hello # Create local (non-exported) variable with value
$ env | grep '^variable='
$ # Still no environment variable called variable
$ export variable # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$
For more information, see the entry for the export
builtin in the GNU Bash manual, and also the sections on command execution environment and environment.
Note that non-exported variables will be available to subshells run via ( ... )
and similar notations because those subshells are direct clones of the main shell:
$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$
The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.
Some information about subshells can be found under command grouping and command execution environment in the Bash manual.
If used in a FragmentActivity, try this:
The first page extends FragmentActivity
Intent Tabdetail = new Intent(getApplicationContext(), ReceivePage.class);
Tabdetail.putExtra("Marker", marker.getTitle().toString());
startActivity(Tabdetail);
In the fragment, you just need to call getActivity()
first,
The second page extends Fragment:
String receive = getActivity().getIntent().getExtras().getString("name");
You can use the JsonTextReader
to read the JSON and iterate over the tokens:
using (var reader = new JsonTextReader(new StringReader(jsonText)))
{
while (reader.Read())
{
Console.WriteLine("{0} - {1} - {2}",
reader.TokenType, reader.ValueType, reader.Value);
}
}
In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.
I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?
Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,
There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.
The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).
Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.
To get all the elements starting with "jander" you should use:

short answer, partial
gives default values to the parameters of a function that would otherwise not have default values.
from functools import partial
def foo(a,b):
return a+b
bar = partial(foo, a=1) # equivalent to: foo(a=1, b)
bar(b=10)
#11 = 1+10
bar(a=101, b=10)
#111=101+10
Don't think so...you can only use openTextFile
for reading (1
), writing (2
), or appending (8
). Reference here.
If you were using VB6 instead of VBScript, you could do:
Open "Filename" [For Mode] [AccessRestriction] [LockType] As #FileNumber
Using the Random
mode. For example:
Open "C:\New\maddy.txt" For Random As #1
A char array is returned by char*, but the function you wrote does not work because you are returning an automatic variable that disappears when the function exits.
Use something like this:
char *testfunc() {
char* arr = malloc(100);
strcpy(arr,"xxxx");
return arr;
}
This is of course if you are returning an array in the C sense, not an std:: or boost:: or something else.
As noted in the comment section: remember to free the memory from the caller.
Most of these answers are either far too complicated or don't seem to work for me (e.g. System.Windows.Input doesn't seem to exist). Then I found some sample code which works fine: http://www.switchonthecode.com/tutorials/winforms-accessing-mouse-and-keyboard-state
In case the page disappears in the future I am posting the relevant source code below:

using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace MouseKeyboardStateTest
{
public abstract class Keyboard
{

private enum KeyStates
{
None = 0,

Toggled = 2
}
[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
private static extern short GetKeyState(int keyCode);
private static KeyStates GetKeyState(Keys key)
{
KeyStates state = KeyStates.None;
short retVal = GetKeyState((int)key);
//If the high-order bit is 1, the key is down
//otherwise, it is up.
if ((retVal & 0x8000) == 0x8000)
state |= KeyStates.Down;
//If the low-order bit is 1, the key is toggled.
if ((retVal & 1) == 1)
state |= KeyStates.Toggled;
return state;
}
public static bool IsKeyDown(Keys key)
{
return KeyStates.Down == (GetKeyState(key) & KeyStates.Down);

By using float you are asking the browser to arrange your controls automatically. It responds by wrapping when the controls don't fit the width for their specified float arrangement. float:left, float:right or clear:left,clear:right,clear:both.
So if you want to force a bunch of float:left items to float uniformly into one left column then you need to make the browser decide to wrap/unwrap them at the same width. Because you don't want to do any scripting you can wrap all of the controls you want to float together in a single div. You would want to add a new wrapping div with a class like:
.LeftImages{
float:left;
}
html
<div class="LeftImages">
<img...>
<img...>
</div>
This div will automatically adjust to the width of the largest image and all the images will be floated left with the div all the time (no wrapping).
If you still want them to wrap you can give the div a width like width:30% and each of the images the float:left; style. Rather than adjust to the largest image it will vary in size and allow the contained images to wrap.
logging
Instead of using the basic print()
function, the more flexible logging
module can be used to log the exception. The logging
module offers a lot extra functionality, e.g. logging messages into a given log file, logging messages with timestamps and additional information about where the logging happened. (For more information check out the official documentation.)
Logging an exception can be done with the module-level function logging.exception()
like so:
import logging
try:
1/0
except BaseException:
logging.exception("An exception was thrown!")
Output:
ERROR:root:An exception was thrown!
Traceback (most recent call last):
File ".../Desktop/test.py", line 4, in <module>
1/0
ZeroDivisionError: division by zero
Notes:
the function logging.exception()
should only be called from an exception handler
the logging
module should not be used inside a logging handler to avoid a RecursionError
(thanks @PrakharPandey)
It's also possible to log the exception with another log-level by using the keyword argument exc_info=True
like so:
logging.debug("An exception was thrown!", exc_info=True)
logging.info("An exception was thrown!", exc_info=True)
logging.warning("An exception was thrown!", exc_info=True)
The problem is that IE won't reset the proxy settings until it either
Below is the code that I've used to get this working:
function Refresh-System
{
$signature = @'
[DllImport("wininet.dll", SetLastError = true, CharSet=CharSet.Auto)]
public static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength);
'@
$INTERNET_OPTION_SETTINGS_CHANGED = 39
$INTERNET_OPTION_REFRESH = 37
$type = Add-Type -MemberDefinition $signature -Name wininet -Namespace pinvoke -PassThru
$a = $type::InternetSetOption(0, $INTERNET_OPTION_SETTINGS_CHANGED, 0, 0)
$b = $type::InternetSetOption(0, $INTERNET_OPTION_REFRESH, 0, 0)
return $a -and $b
}
Why all people want to use '==' instead of simple '=' ? It is bad habit! It used only in [[ ]] expression. And in (( )) too. But you may use just = too! It work well in any case. If you use numbers, not strings use not parcing to strings and then compare like strings but compare numbers. like that
let -i i=5 # garantee that i is nubmber
test $i -eq 5 && echo "$i is equal 5" || echo "$i not equal 5"
It's match better and quicker. I'm expert in C/C++, Java, JavaScript. But if I use bash i never use '==' instead '='. Why you do so?
You may see this error when you have added a new file to your code and you're now trying to commit the code without staging(adding) it.
To overcome this, you may first add the file by using git add (git add your_file_name.py
) and then committing the changes (git commit -m "Rename Files" -m "Sample script to rename files as you like"
)
Sometimes when your table has a similar name to the database name you should use back tick. so instead of:
INSERT INTO books.book(field1, field2) VALUES ('value1', 'value2');
You should have this:
INSERT INTO `books`.`book`(`field1`, `field2`) VALUES ('value1', 'value2');
If you need to order your code into namespaces, just use the keyword namespace
:
file1.php
namespace foo\bar;
In file2.php
$obj = new \foo\bar\myObj();
You can also use use
. If in file2 you put
use foo\bar as mypath;
you need to use mypath
instead of bar
anywhere in the file:
$obj = new mypath\myObj();
Using use foo\bar;
is equal to use foo\bar as bar;
.
a simple getchar() should do just fine.
For those like me, who have reached this thread because they want to serve an html file from linux terminal or want to view it using a terminal command, use these steps:-
1)If you want to view your html using a browser:-
Navigate to the directory containing the html file
If you have chrome installed, Use:-
google-chrome <filename>.html
OR
Use:-
firefox <filename>.html
2)If you want to serve html file and view it using a browser
Navigate to the directory containing the html file
And Simply type the following on the Terminal:-
pushd <filename>.html; python3 -m http.server 9999; popd;
Then click the I.P. address 0.0.0.0:9999 OR localhost:9999 (Whatever is the result after executing the above commands). Or type on the terminal :-
firefox 0.0.0.0:9999
Using the second method, anyone else connected to the same network can also view your file by using the URL:- "0.0.0.0:9999"

This is hopefully a bit more random than just using srand(time(NULL))
.
#include <time.h>
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv)

srand((unsigned int)**main + (unsigned int)&argc + (unsigned int)time(NULL));
srand(rand());
for (int i = 0; i < 10; i++)
printf("%d\n", rand());
}
If you want to do it in code, use the System.Web.HttpCookie.HttpOnly property.
This is directly from the MSDN docs:
// Create a new HttpCookie.
HttpCookie myHttpCookie = new HttpCookie("LastVisit", DateTime.Now.ToString());
// By default, the HttpOnly property is set to false
// unless specified otherwise in configuration.
myHttpCookie.Name = "MyHttpCookie";
Response.AppendCookie(myHttpCookie);
// Show the name of the cookie.
Response.Write(myHttpCookie.Name);
// Create an HttpOnly cookie.
HttpCookie myHttpOnlyCookie = new HttpCookie("LastVisit", DateTime.Now.ToString());
// Setting the HttpOnly value to true, makes
// this cookie accessible only to ASP.NET.
myHttpOnlyCookie.HttpOnly = true;
myHttpOnlyCookie.Name = "MyHttpOnlyCookie";
Response.AppendCookie(myHttpOnlyCookie);
// Show the name of the HttpOnly cookie.
Response.Write(myHttpOnlyCookie.Name);
Doing it in code allows you to selectively choose which cookies are HttpOnly and which are not.

You could also make the ajax call more generic, reusable, so you can call it from different CRUD(create, read, update, delete) tasks for example and treat the success cases from those calls.
makePostCall = function (url, data) { // here the data and url are not hardcoded anymore
var json_data = JSON.stringify(data);
return $.ajax({
type: "POST",
url: url,
data: json_data,
dataType: "json",
contentType: "application/json;charset=utf-8"
});
}
// and here a call example
makePostCall("index.php?action=READUSERS", {'city' : 'Tokio'})
.success(function(data){
// treat the READUSERS data returned
})
.fail(function(sender, message, details){
alert("Sorry, something went wrong!");
});

You can do it server side: by measuring the image and then setting the div size, OR loading the image with JS, read it's attributes and then set the DIV size.
And here is an idea, put the same image inside the div as an IMG tag, but give it visibility: hidden + play with position relative+ give this div the image as background.

Since the advent of p2, you should be using the dropins directory instead.
To be completely clear create "plugins" under "/dropins" and make sure to restart eclipse with the "-clean" option.
You just can put your query as a subquery:
SELECT avg(count)
FROM
(
SELECT COUNT (*) AS Count
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time )
FROM Table B
WHERE (B.Id = T.Id))
GROUP BY T.Grouping
) as counts
Edit: I think this should be the same:
SELECT count(*) / count(distinct T.Grouping)
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time)
FROM Table B
WHERE (B.Id = T.Id))
I'm not sure if this works for you, but when I do small solo PHP projects with Eclipse, the first thing I set up is an Ant script for deploying the project to a remote testing environment. I code away locally, and whenever I want to test it, I just hit the shortcut which updates the remote site.
Eclipse has good Ant support out of the box, and the scripts aren't hard to make.

The utf8mb4, utf16, and utf32 character sets were added in MySQL 5.5.3.

The best thing to do is to remove Node.js from the control panel. Once deleted download the desired version of Node.js and install it and it works.
I had the same issue. The problem was because 'ng-controller' was defined twice (in routing and also in the HTML).
It is the 1).spinning and 2).polling loop of your examples that people caution against, not the Thread.Sleep() part. I think Thread.Sleep() is usually added to easily improve code that is spinning or in a polling loop, so it is just associated with "bad" code.
In addition people do stuff like:
while(inWait)Thread.Sleep(5000);
where the variable inWait is not accessed in a thread-safe manner, which also causes problems.
What programmers want to see is the threads controlled by Events and Signaling and Locking constructs, and when you do that you won't have need for Thread.Sleep(), and the concerns about thread-safe variable access are also eliminated. As an example, could you create an event handler associated with the FileSystemWatcher class and use an event to trigger your 2nd example instead of looping?
As Andreas N. mentioned, read Threading in C#, by Joe Albahari, it is really really good.
After few hours of searching, I just solved this issue with a few lines of code
Your model
[Required(ErrorMessage = "Enter the issued date.")]
[DataType(DataType.Date)]
public DateTime IssueDate { get; set; }
Razor Page
@Html.TextBoxFor(model => model.IssueDate)
@Html.ValidationMessageFor(model => model.IssueDate)
Jquery DatePicker
<script type="text/javascript">
$(document).ready(function () {
$('#IssueDate').datepicker({
dateFormat: "dd/mm/yy",
showStatus: true,
showWeeks: true,
currentText: 'Now',
autoSize: true,
gotoCurrent: true,
showAnim: 'blind',
highlightWeek: true
});
});
</script>
Webconfig File
<system.web>
<globalization uiCulture="en" culture="en-GB"/>
</system.web>
Now your text-box will accept "dd/MM/yyyy" format.
Providing credentials on the command line is not a good idea. The above answers are great, but neglect to mention
mysql --defaults-extra-file=etc/myhost.cnf database_name < file.sql
Where etc/myhost.cnf is a file that contains host, user, password, and you avoid exposing the password on the command line. Here is a sample,
[client]
host=hostname.domainname
user=dbusername
password=dbpassword
Will the conditions be ORed or ANDed together?
Starts with: abc Ends with: xyz Contains: 123 Doesn't contain: 456
The OR version is fairly simple; as you said, it's mostly a matter of inserting pipes between individual conditions. The regex simply stops looking for a match as soon as one of the alternatives matches.
/^abc|xyz$|123|^(?:(?!456).)*$/
That fourth alternative may look bizarre, but that's how you express "doesn't contain" in a regex. By the way, the order of the alternatives doesn't matter; this is effectively the same regex:
/xyz$|^(?:(?!456).)*$|123|^abc/
The AND version is more complicated. After each individual regex matches, the match position has to be reset to zero so the next regex has access to the whole input. That means all of the conditions have to be expressed as lookaheads (technically, one of them doesn't have to be a lookahead, I think it expresses the intent more clearly this way). A final .*$
consummates the match.
/^(?=^abc)(?=.*xyz$)(?=.*123)(?=^(?:(?!456).)*$).*$/
And then there's the possibility of combined AND and OR conditions--that's where the real fun starts. :D
You didn't specify a GradientType
:
background: #f0f0f0; /* Old browsers */
background: -moz-linear-gradient(top, #ffffff 0%, #eeeeee 100%); /* FF3.6+ */

I've settled on the following format for typing arrays that can have items of multiple types.
Array<ItemType1 | ItemType2 | ItemType3>
This works well with testing and type guards. https://www.typescriptlang.org/docs/handbook/advanced-types.html#type-guards-and-differentiating-types
This format doesn't work well with testing or type guards:
(ItemType1 | ItemType2 | ItemType3)[]
Remove all spaces in string
// Remove only spaces
`
Text with spaces 1 1 1 1
and some
breaklines
`.replace(/ /g,'');
"
Textwithspaces1111
andsome
breaklines
"
// Remove spaces and breaklines
`
Text with spaces 1 1 1 1
and some
breaklines
`.replace(/\s/g,'');
"Textwithspaces1111andsomebreaklines"
I couldn't write a comment, so I write here:
double.Parse("3.5", CultureInfo.InvariantCulture) is not a good idea, because in Canada we write 3,5 instead of 3.5 and this function gives us 35 as a result.
I tested both on my computer:
double.Parse("3.5", CultureInfo.InvariantCulture) --> 3.5 OK
double.Parse("3,5", CultureInfo.InvariantCulture) --> 35 not OK
This is a correct way that Pierre-Alain Vigeant mentioned
public static double GetDouble(string value, double defaultValue)
{
double result;
// Try parsing in the current culture
if (!double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.CurrentCulture, out result) &&
// Then try in US english
!double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.GetCultureInfo("en-US"), out result) &&
// Then in neutral language
!double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.InvariantCulture, out result))
{
result = defaultValue;
}
return result;
}
You put <=
and it will catch the given date too. You can replace it with <
only.
jnettop is another candidate.

Both of the examples immediately above didn't work for me. Opening a recordset on the table and adding a record does work to add the record, except:
myLong = CLng(rs!AutoNumberField)
returns Null if put between rs.AddNew and rs.Update. If put after rs.Update, it does return something, but it's always wrong, and always the same incorrect value. Looking at the table directly after adding the new record shows an autonumber field value different than the one returned by the above statement.
myLong = DLookup("AutoNumberField","TableName","SomeCriteria")
will work properly, as long as it's done after rs.Update, and there are any other fields which can uniquely identify the record.
File mode, write and binary. Since you are writing a .jpg file, it looks fine.
But if you supposed to read that jpg file you need to use 'rb'
More info
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.

I won't talk much. Already my respected fellow friends have given their valuable input. The full fledged running code at the last of this blog should remove any confusion. It's about a movie seat booking small program in multi-threaded scenario.
Some important elementary facts are as follows. 1> Different threads can only contend for instance and static member variables in the heap space. 2> Volatile read or write are completely atomic and serialized/happens before and only done from memory. By saying this I mean that any read will follow the previous write in memory. And any write will follow the previous read from memory. So any thread working with a volatile will always see the most up-to-date value. AtomicReference uses this property of volatile.
Following are some of the source code of AtomicReference. AtomicReference refers to an object reference. This reference is a volatile member variable in the AtomicReference instance as below.
private volatile V value;
get() simply returns the latest value of the variable (as volatiles do in a "happens before" manner).
public final V get()
Following is the most important method of AtomicReference.
public final boolean compareAndSet(V expect, V update) {
return unsafe.compareAndSwapObject(this, valueOffset, expect, update);
}
The compareAndSet(expect,update) method calls the compareAndSwapObject() method of the unsafe class of Java. This method call of unsafe invokes the native call, which invokes a single instruction to the processor. "expect" and "update" each reference an object.
If and only if the AtomicReference instance member variable "value" refers to the same object is referred to by "expect", "update" is assigned to this instance variable now, and "true" is returned. Or else, false is returned. The whole thing is done atomically. No other thread can intercept in between. As this is a single processor operation (magic of modern computer architecture), it's often faster than using a synchronized block. But remember that when multiple variables need to be updated atomically, AtomicReference won't help.
I would like to add a full fledged running code, which can be run in eclipse. It would clear many confusion. Here 22 users (MyTh threads) are trying to book 20 seats. Following is the code snippet followed by the full code.

Leaving the disabled flag in prevents them from not selecting an option and the hidden flag will remove it from the list. In my case I was using it with an enum list as well and the concept holds the same

<option value="" selected disabled hidden>Select Property Enum</option>
<option value=""></option>

The official Jenkins documentation only mentions single line commands like the following:
// Declarative //
and (see)
pipeline {
/* insert Declarative Pipeline here */
}
The syntax of the Jenkinsfile is based on Groovy so it is also possible to use groovy syntax for comments. Quote:
/* a standalone multiline comment
spanning two lines */
println "hello" /* a multiline comment starting
at the end of a statement */
println 1 /* one */ + 2 /* two */
or
/**

Just store the index generated in a variable, and then access the array using this varaible:
int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);
P.S. I usually don't like generating new Random
object per randoization - I prefer using a single Random
in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.
According to this approach, I will have some variable Random r
somewhere, and I will just use:
int idx = r.nextInt(fruits.length)
However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.
Your query has 8 or possibly even 9 variables, ie. Name, Description etc. But the values, these things ---> '', '%s', '%s', '%s', '%s', '%s', '%s', '%s')"
, only total 7, the number of variables have to be the same as the values.
I had the same problem but I figured it out. Hopefully it will also work for you.
If you want to use it in plain SQL, I would let the store procedure fill a table or temp table with the resulting rows (or go for @Tony Andrews approach).
If you want to use @Thilo's solution, you have to loop the cursor using PL/SQL.
Here an example: (I used a procedure instead of a function, like @Thilo did)
create or replace procedure myprocedure(retval in out sys_refcursor) is
begin
open retval for
select TABLE_NAME from user_tables;
end myprocedure;
declare
myrefcur sys_refcursor;
tablename user_tables.TABLE_NAME%type;
begin
myprocedure(myrefcur);
loop
fetch myrefcur into tablename;
exit when myrefcur%notfound;
dbms_output.put_line(tablename);
end loop;
close myrefcur;
end;
Whenever these plugins and options aren't available I just use my good ol friend notepad. Paste content into notepad where it won't accept the extra formatting and then copy it right back out. Sort of hacky but oh well. It works!
You're not working with strings. You're working with pointers.
var1
is a char pointer (const char*
). It is not a string. If it is null-terminated, then certain C functions will treat it as a string, but it is fundamentally just a pointer.
So when you compare it to a char array, the array decays to a pointer as well, and the compiler then tries to find an operator == (const char*, const char*)
.
Such an operator does exist. It takes two pointers and returns true
if they point to the same address. So the compiler invokes that, and your code breaks.
IF you want to do string comparisons, you have to tell the compiler that you want to deal with strings, not pointers.
The C way of doing this is to use the strcmp
function:
strcmp(var1, "dev");
This will return zero if the two strings are equal. (It will return a value greater than zero if the left-hand side is lexicographically greater than the right hand side, and a value less than zero otherwise.)
So to compare for equality you need to do one of these:
if (!strcmp(var1, "dev")){...}
if (strcmp(var1, "dev") == 0) {...}
However, C++ has a very useful string
class. If we use that your code becomes a fair bit simpler. Of course we could create strings from both arguments, but we only need to do it with one of them:
std::string var1 = getenv("myEnvVar");
if(var1 == "dev")
{
// do stuff
}
Now the compiler encounters a comparison between string and char pointer. It can handle that, because a char pointer can be implicitly converted to a string, yielding a string/string comparison. And those behave exactly as you'd expect.
So by adding the #!/bin/sh
will allow you to execute with no option.
It also helped me in fixing an issue where I was executing bash script from Jenkins master on my Linux slave. By just adding #!/bin/bash
above my actual script in "Execute Shell" block it fixed my issue as otherwise it was executing windows git provided version of bash shell that was giving an error.
Found the solution:
UltraPictureBox1.Image = _
My.Resources.ResourceManager.GetObject(object_name_as_string)
Based on Olivier Refalo's answer
if [ $# -eq 2 ]
then
echo "Setting tracking for branch " $1 " -> " $2
git branch --set-upstream $1 $2
else
echo "-- Local --"
git for-each-ref --shell --format="[ %(upstream:short) != '' ] && echo -e '\t%(refname:short) <--> %(upstream:short)'" refs/heads | sh
echo "-- Remote --"
REMOTES=$(git remote -v)
if [ "$REMOTES" != '' ]
then
echo $REMOTES
fi
fi
It shows only local with track configured.
Write it on a script called git-track on your path an you will get a git track command

One alternative would be a KeyedCollection if the key is embedded in the value.
Just create a basic implementation in a sealed class to use.
So to replace Dictionary<string, int>
(which isn't a very good example as there isn't a clear key for a int).
private sealed class IntDictionary : KeyedCollection<string, int>
{
protected override string GetKeyForItem(int item)
{
// The example works better when the value contains the key. It falls down a bit for a dictionary of ints.
return item.ToString();
}
}
KeyedCollection<string, int> intCollection = new ClassThatContainsSealedImplementation.IntDictionary();
intCollection.Add(7);
int valueByIndex = intCollection[0];
[Based on Android source code:]
At the C++ side, the SurfaceFlinger implements the captureScreen API. This is exposed over the binder IPC interface, returning each time a new ashmem area that contains the raw pixels from the screen. The actual screenshot is taken through OpenGL.
For the system C++ clients, the interface is exposed through the ScreenshotClient class, defined in <surfaceflinger_client/SurfaceComposerClient.h>
for Android < 4.1; for Android > 4.1 use <gui/SurfaceComposerClient.h>
Before JB, to take a screenshot in a C++ program, this was enough:
ScreenshotClient ssc;
ssc.update();
With JB and multiple displays, it becomes slightly more complicated:
ssc.update(
android::SurfaceComposerClient::getBuiltInDisplay(
android::ISurfaceComposer::eDisplayIdMain));
Then you can access it:
do_something_with_raw_bits(ssc.getPixels(), ssc.getSize(), ...);
Using the Android source code, you can compile your own shared library to access that API, and then expose it through JNI to Java. To create a screen shot form your app, the app has to have the READ_FRAME_BUFFER
permission.
But even then, apparently you can create screen shots only from system applications, i.e. ones that are signed with the same key as the system. (This part I still don't quite understand, since I'm not familiar enough with the Android Permissions system.)
Here is a piece of code, for JB 4.1 / 4.2:
#include <utils/RefBase.h>
#include <binder/IBinder.h>
#include <binder/MemoryHeapBase.h>
#include <gui/ISurfaceComposer.h>
#include <gui/SurfaceComposerClient.h>
static void do_save(const char *filename, const void *buf, size_t size) {
int out = open(filename, O_RDWR|O_CREAT, 0666);
int len = write(out, buf, size);
printf("Wrote %d bytes to out.\n", len);
close(out);
}
int main(int ac, char **av) {
android::ScreenshotClient ssc;
const void *pixels;
size_t size;
int buffer_index;
if(ssc.update(
android::SurfaceComposerClient::getBuiltInDisplay(
android::ISurfaceComposer::eDisplayIdMain)) != NO_ERROR ){
printf("Captured: w=%d, h=%d, format=%d\n");
ssc.getWidth(), ssc.getHeight(), ssc.getFormat());
size = ssc.getSize();
do_save(av[1], pixels, size);
}
else
printf(" screen shot client Captured Failed");
return 0;
}
I think the nicest option to do this in chartJS v2.x is by using a plugin, so you don't have a large block of code in the options. In addition, it prevents the data from disappearing when hovering over a bar.
I.e. simply use this code, which registers a plugin that adds the text after the chart is drawn.
Chart.pluginService.register({
afterDraw: function(chartInstance) {
var ctx = chartInstance.chart.ctx;
// render the value of the chart above the bar
ctx.font = Chart.helpers.fontString(Chart.defaults.global.defaultFontSize, 'normal', Chart.defaults.global.defaultFontFamily);
ctx.textAlign = 'center';
ctx.textBaseline = 'bottom';
chartInstance.data.datasets.forEach(function (dataset) {
for (var i = 0; i < dataset.data.length; i++) {
var model = dataset._meta[Object.keys(dataset._meta)[0]].data[i]._model;
ctx.fillText(dataset.data[i], model.x, model.y - 2);
}
});
}
});
In special cases where you want to find whether a word is contained in a long text, you can iterate through the long text with a loop.
found=F
query_word=this
long_string="many many words in this text"
for w in $long_string; do
if [ "$w" = "$query_word" ]; then
found=T
break
fi
done
This is pure Bourne shell.
A literal translation of the mathematical definition is quite adequate in a lot of cases (remembering that Python will automatically use big number arithmetic):
from math import factorial
def calculate_combinations(n, r):
return factorial(n) // factorial(r) // factorial(n-r)
For some inputs I tested (e.g. n=1000 r=500) this was more than 10 times faster than the one liner reduce
suggested in another (currently highest voted) answer. On the other hand, it is out-performed by the snippit provided by @J.F. Sebastian.
In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to
Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).
In other words: Whenever the interpreter encounters the sequence <space>
_
<line terminator>
, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.
To break the statement in your question into several lines you could do the following:
U_matrix(i, j, n + 1) = _
k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
(k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))
(Leading whitespaces are ignored.)
Vertical scroll, good for forms. Answer is based on Ahmadalibaloch horizontal scroll.
private final void focusOnView(final HorizontalScrollView scroll, final View view) {
new Handler().post(new Runnable() {
@Override
public void run() {
int top = view.getTop();
int bottom = view.getBottom();
int sHeight = scroll.getHeight();
scroll.smoothScrollTo(0, ((top + bottom - sHeight) / 2));
}
});
}
In fact if you write any C extensions for your Ruby projects there is really only one way to define a Module method.
rb_define_singleton_method
I know this self business just opens up all kinds of other questions so you could do better by searching each part.
Objects first.
foo = Object.new
Can I make a method for foo?
Sure
def foo.hello
'hello'
end
What do I do with it?
foo.hello
==>"hello"
Just another object.
foo.methods
You get all the Object methods plus your new one.
def foo.self
self
end
foo.self
Just the foo Object.
Try to see what happens if you make foo from other Objects like Class and Module. The examples from all the answers are nice to play with but you have to work with different ideas or concepts to really understand what is going on with the way the code is written. So now you have lots of terms to go look at.
Singleton, Class, Module, self, Object, and Eigenclass was brought up but Ruby doesn't name Object Models that way. It's more like Metaclass. Richard or __why shows you the idea here. http://viewsourcecode.org/why/hacking/seeingMetaclassesClearly.html And if the blows you away then try looking up Ruby Object Model in search. Two videos that I know of on YouTube are Dave Thomas and Peter Cooper. They try to explain that concept too. It took Dave a long time to get it so don't worry. I'm still working on it too. Why else would I be here? Thanks for your question. Also take a look at the standard library. It has a Singleton Module just as an FYI.
This is pretty good. https://www.youtube.com/watch?v=i4uiyWA8eFk
You could always add Double.MinValue
to the sequence. This would ensure that there is at least one element and Max
would return it only if it is actually the minimum. To determine which option is more efficient (Concat
, FirstOrDefault
or Take(1)
), you should perform adequate benchmarking.
double x = context.MyTable
.Where(y => y.MyField == value)
.Select(y => y.MyCounter)
.Concat(new double[]{Double.MinValue})
.Max();
From the Python glossary:
An object is hashable if it has a hash value which never changes during its lifetime (it needs a
__hash__()
method), and can be compared to other objects (it needs an__eq__()
or__cmp__()
method). Hashable objects which compare equal must have the same hash value.Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally.
All of Python’s immutable built-in objects are hashable, while no mutable containers (such as lists or dictionaries) are. Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their
id()
.

You want to use pyplot.grid
:
x = numpy.arange(0, 1, 0.05)
y = numpy.power(x, 2)
fig = plt.figure()
ax = fig.gca()
ax.set_xticks(numpy.arange(0, 1, 0.1))
ax.set_yticks(numpy.arange(0, 1., 0.1))
plt.scatter(x, y)
plt.grid()
plt.show()
ax.xaxis.grid
and ax.yaxis.grid
can control grid lines properties.
I was running into the same problem and after some trial and error discovered that my hosts
file customisation was causing the problem.
My localhost
DNS was overwritten and because of that a simple ping was failing:
$ ping http://localhost
# ping: cannot resolve http://localhost: Unknown host
Once I resolved the configuration of /private/etc/hosts
file, pinging localhost
successfully worked, and was no longer getting the error that you were seeing:
# Fatal error: getaddrinfo ENOTFOUND
LocalDate.now()
.toString()
2017-01-23
Better to specify the desired/expected time zone explicitly.
LocalDate.now( ZoneId.of( "America/Montreal" ) )
.toString()
The modern way as of Java 8 and later is with the java.time framework.
Specify the time zone, as the date varies around the world at any given moment.
ZoneId zoneId = ZoneId.of( "America/Montreal" ) ; // Or ZoneOffset.UTC or ZoneId.systemDefault()
LocalDate today = LocalDate.now( zoneId ) ;
String output = today.toString() ;
2017-01-23
By default you get a String in standard ISO 8601 format.
For other formats use the java.time.format.DateTimeFormatter
class.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
The easiest solution to workaround this is to create 'temporary' input with type submit and trigger click:

$("#aspnetForm").append(submitInput);
submitInput.trigger("click");
#sort dataframe by col
sort.df <- with(df, df[order(sortbythiscolumn) , ])
#can also sort by more than one variable: sort by col1 and then by col2
sort2.df <- with(df, df[order(col1, col2) , ])
#sort in reverse order
sort2.df <- with(df, df[order(col1, -col2) , ])
Instead of selecting all the columns in count count(*) you can limit count for one column count(UserName).
You can limit the whole search to one row by using Limit 0,1
SELECT COUNT(UserName)
FROM TableName
WHERE UserName = 'User' AND
Password = 'Pass'
LIMIT 0, 1

As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x
git push --atomic origin <branch name> <tag>
(Note: this actually work with HTTPS only with Git 2.24)
As of git 2.4.1, you can do
git config --global push.followTags true
If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.
As noted in this thread by Matt Rogers answering Wes Hurd:
--follow-tags
only pushes annotated tags.
git tag -a -m "I'm an annotation" <tagname>
That would be pushed (as opposed to git tag <tagname>
, a lightweight tag, which would not be pushed, as I mentioned here)
Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:
The new "
--follow-tags
" option tells "git push
" to push relevant annotated tags when pushing branches out.
You can now try, when pushing new commits:
git push --follow-tags
That won't push all the local tags though, only the one referenced by commits which are pushed with the git push
.
Git 2.4.1+ (Q2 2015) will introduce the option push.followTags
: see "How to make “git push
” include tags within a branch?".
The nuclear option would be git push --mirror
, which will push all refs under refs/
.
You can also push just one tag with your current branch commit:
git push origin : v1.0.0
You can combine the --tags
option with a refspec like:
git push origin --tags :
(since --tags
means: All refs under refs/tags
are pushed, in addition to refspecs explicitly listed on the command line)
You also have this entry "Pushing branches and tags with a single "git push" invocation"
A handy tip was just posted to the Git mailing list by Zoltán Füzesi:
I use
.git/config
to solve this:
[remote "origin"]
url = ...
fetch = +refs/heads/*:refs/remotes/origin/*
push = +refs/heads/*
push = +refs/tags/*
With these lines added
git push origin
will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.
Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:
$ git push && git push --tags
Beware, as commented by Aseem Kishore
push = +refs/heads/*
will force-pushes all your branches.
This bit me just now, so FYI.
René Scheibe adds this interesting comment:
The
--follow-tags
parameter is misleading as only tags under.git/refs/tags
are considered.
Ifgit gc
is run, tags are moved from.git/refs/tags
to.git/packed-refs
. Afterwardsgit push --follow-tags ...
does not work as expected anymore.
VanDyke VShell is the best Windows SSH Server I've ever worked with. It is kind of expensive though ($250). If you want a free solution, freeSSHd works okay. The CYGWIN solution is always an option, I've found, however, that it is a lot of work & overhead just to get SSH.
When you see the "Cannot evaluate expression because the code of the current method is optimized." message after issuing a Debugger.Break()
statement then please make sure you press F10 to step to the next statement.
Once stepped to the next statement, and assuming you are running a Debug build, this message should disappear.
Not sure, but what I think you're looking for is to create a java.util.Date from a String, then convert that java.util.Date to a java.sql.Date.
try this:
private static java.sql.Date getCurrentDate(String date) {
java.util.Date today;
java.sql.Date rv = null;
try {
SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");
today = format.parse(date);
rv = new java.sql.Date(today.getTime());
System.out.println(rv.getTime());
} catch (Exception e) {
System.out.println("Exception: " + e.getMessage());
} finally {
return rv;
}
}
Will return a java.sql.Date object for setDate();
The function above will print out a long value:
1375934400000
Try to use appendChild method:
select.appendChild(option);
Here is my code without using eval
. Its easy to understand too.
function value(obj, props) {
if (!props) return obj;
var propsArr = props.split('.');
var prop = propsArr.splice(0, 1);
return value(obj[prop], propsArr.join('.'));
}
var obj = { a: { b: '1', c: '2', d:{a:{b:'blah'}}}};
console.log(value(obj, 'a.d.a.b')); //returns blah
Try running
lsof | grep /mnt/data
That should list any process that is accessing /mnt/data that would prevent it from being unmounted.
If you want a real database default value, use columnDefinition
:
@Column(name = "myColumn", nullable = false, columnDefinition = "int default 100")
Notice that the string in columnDefinition
is database dependent. Also if you choose this option, you have to use dynamic-insert
, so Hibernate
doesn't include columns with null
values on insert. Otherwise talking about default is irrelevant.
But if you don't want database default value, but simply a default value in your Java code, just initialize your variable like that - private Integer myColumn = 100;
<textarea style="resize:none" rows="10" placeholder="Enter Text" ></textarea>
Another way to check where a specific table is stored would be execute this query on the hive interactive interface:
show create table table_name;
where table_name is the name of the subject table.
An example for the above query on 'customers' table would be something like this:
CREATE TABLE `customers`(
`id` string,
`name` string)
COMMENT 'Imported by sqoop on 2016/03/01 13:01:49'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
STORED AS INPUTFORMAT
'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
'hdfs://quickstart.cloudera:8020/user/hive/warehouse/
sqoop_workspace.db/customers'
TBLPROPERTIES (
'COLUMN_STATS_ACCURATE'='true',
'numFiles'='4',
'totalSize'='77',
'transient_lastDdlTime'='1456866115')
LOCATION in the example above is where you should focus on. That is your hdfs location for hive warehouse.
Don't forget to like if you like this solution. Cheers!

To save a package to package.json as dev dependencies:
npm install "$package" --save-dev
When you run npm install
it will install both devDependencies
and dependencies
. To avoid install devDependencies
run:
npm install --production
Just because you don't know what two things are, does not mean they're equal. If when you think of NULL
you think of “NULL” (string) then you probably want a different test of equality like Postgresql's IS DISTINCT FROM
AND IS NOT DISTINCT FROM
From the PostgreSQL docs on "Comparison Functions and Operators"
expression
IS DISTINCT FROM
expressionexpression
IS NOT DISTINCT FROM
expressionFor non-null inputs,
IS DISTINCT FROM
is the same as the<>
operator. However, if both inputs are null it returns false, and if only one input is null it returns true. Similarly,IS NOT DISTINCT FROM
is identical to=
for non-null inputs, but it returns true when both inputs are null, and false when only one input is null. Thus, these constructs effectively act as though null were a normal data value, rather than "unknown".
The first is easiest(involves less typing), and it is guaranteed to work, all members will be set to 0
[Ref 1].
The second is more readable.
The choice depends on user preference or the one which your coding standard mandates.
[Ref 1] Reference C99 Standard 6.7.8.21:
If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

Another option if you can't get it working for some reason is to simply mount a logdir directory on your filesystem with sshfs:
sshfs user@host:/home/user/project/summary_logs ~/summary_logs
and then run Tensorboard locally.
try piping output of find (ie. the file path) into cpio
find . -type f -name '*.jpg' | cpio -p -d -v targetdir/
cpio checks timestamp on target files -- so its safe and fast.
remove -v for faster op, once you get used to it.
If you need to iterate over a queue
then you need something more than a queue. The point of the standard container adapters is to provide a minimal interface. If you need to do iteration as well, why not just use a deque (or list) instead?
If you are declaring your pipe in another module, make sure to add it to that module Declarations and Exports array, then import that module in whatever module is consuming that pipe.
You need to link both a.o
and b.o
:
gcc -o program a.c b.c
If you have a main()
in each file, you cannot link them together.
However, your a.c
file contains a reference to doSomething()
and expects to be linked with a source file that defines doSomething()
and does not define any function that is defined in a.c
(such as main()
).
You cannot call a function in Process B from Process A. You cannot send a signal to a function; you send signals to processes, using the kill()
system call.
The signal()
function specifies which function in your current process (program) is going to handle the signal when your process receives the signal.
You have some serious work to do understanding how this is going to work - how ProgramA is going to know which process ID to send the signal to. The code in b.c
is going to need to call signal()
with dosomething
as the signal handler. The code in a.c
is simply going to send the signal to the other process.
Use Range("A1").Text
instead of .Value
post comment edit:
Why?
Because the .Text
property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92
then <- Text
will return exactly what it in the cell including any formatting.
The .Value
and .Value2
properties return what's stored in the cell under the hood excluding formatting. Specially .Value2
for date types, it will return the decimal representation.
If you want to dig deeper into the meaning and performance, I just found this article
which seems like a good guide
another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage
now,
paste this code in a module
Sub main()
Dim ws As Worksheet, i&, j&
Set ws = Sheets(1)
For i = 3 To 7
For j = 1 To 4
Debug.Print _
"row " & i & vbTab & vbTab & _
Cells(i, j).Text & vbTab & _
Cells(i, j).Value & vbTab & _
Cells(i, j).Value2
Next j
Next i
End Sub
and Analyse
the output! Its really easy and there isn't much more i can do to help :)

While you can execute backup commands from PHP, they don't really have anything to do with PHP. It's all about MySQL.
I'd suggest using the mysqldump utility to back up your database. The documentation can be found here : http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html.
The basic usage of mysqldump is
mysqldump -u user_name -p name-of-database >file_to_write_to.sql
You can then restore the backup with a command like
mysql -u user_name -p <file_to_read_from.sql
Do you have access to cron? I'd suggest making a PHP script that runs mysqldump as a cron job. That would be something like
<?php
$filename='database_backup_'.date('G_a_m_d_y').'.sql';
$result=exec('mysqldump database_name --password=your_pass --user=root --single-transaction >/var/backups/'.$filename,$output);
if(empty($output)){/* no output is good */}
else {/* we have something to log the output here*/}
If mysqldump is not available, the article describes another method, using the SELECT INTO OUTFILE
and LOAD DATA INFILE
commands. The only connection to PHP is that you're using PHP to connect to the database and execute the SQL commands. You could also do this from the command line MySQL program, the MySQL monitor.
It's pretty simple, you're writing an SQL file with one command, and loading/executing it when it's time to restore.
You can find the docs for select into outfile here (just search the page for outfile). LOAD DATA INFILE is essentially the reverse of this. See here for the docs.
I want to select the text of a string that is located after the occurrence of substring
You could use:
substring-after($string,$match)
If you want a subtring of the above with some length then use:
substring(substring-after($string,$match),1,$length)
But problems begin if there is no ocurrence of the matching substring... So, if you want a substring with specific length located after the occurrence of a substring, or from the whole string if there is no match, you could use:
substring(substring-after($string,substring-before($string,$match)),
string-length($match) * contains($string,$match) + 1,
$length)
Simple way to set it in visual studio IDE.

Could you provide a whole makefile? But right now I can tell - you should check that "install" target already exists. So, check Makefile whether it contains a
install: (anything there)
line. If not, there is no such target and so make has right. Probably you should use just "make" command to compile and then use it as is or install yourself, manually.
Install is not any standard of make, it is just a common target, that could exists, but not necessary.
==
shouldn't be used to compare objects in your if
. For NSString
use isEqualToString:
to compare them.
Classes are objects with attributes (state, characteristic) and methods (functions, capacities) that are specific for that object (like the white color and fly powers, respectively, for a duck).
When you create an instance of a class, you can give it some initial personality (state or character like the name and the color of her dress for a newborn). You do this with __init__
.
Basically __init__
sets the instance characteristics automatically when you call instance = MyClass(some_individual_traits)
.
Use the entity code  
instead.
is a HTML "character entity reference". There is no named entity for non-breaking space in XML, so you use the code  
.
Wikipedia includes a list of XML and HTML entities, and you can see that there are only 5 "predefined entities" in XML, but HTML has over 200. I'll also point over to Creating a space ( ) in XSL which has excellent answers.
I always seem to find myself landing here only to realize that the title and question are not quite aligned.
If you want a moment date from a string:
const myMomentObject = moment(str, 'YYYY-MM-DD')
From moment documentation:
Instead of modifying the native Date.prototype, Moment.js creates a wrapper for the Date object.
If you instead want a javascript Date object from a string:
const myDate = moment(str, 'YYYY-MM-DD').toDate();
