The simplest solution is a join with USING
instead of ON
. That way, the database "knows" that both id
columns are actually the same, and won't nitpick on that:
SELECT id, name, section
FROM tbl_names
JOIN tbl_section USING (id)
If id
is the only common column name in tbl_names
and tbl_section
, you can even use a NATURAL JOIN
:
SELECT id, name, section
FROM tbl_names
NATURAL JOIN tbl_section
If you want the last row for each Name
, then you can give a row number to each row group by the Name
and order by Id
in descending order.
QUERY
SELECT t1.Id,
t1.Name,
t1.Other_Columns
FROM
(
SELECT Id,
Name,
Other_Columns,
(
CASE Name WHEN @curA
THEN @curRow := @curRow + 1
ELSE @curRow := 1 AND @curA := Name END
) + 1 AS rn
FROM messages t,
(SELECT @curRow := 0, @curA := '') r
ORDER BY Name,Id DESC
)t1
WHERE t1.rn = 1
ORDER BY t1.Id;
wsExists
function (without reliance on Error Handling!)Here's a short & simple function that doesn't rely on error handling to determine whether a worksheet exists (and is properly declared to work in any situation!)
Function wsExists(wsName As String) As Boolean
Dim ws: For Each ws In Sheets
wsExists = (wsName = ws.Name): If wsExists Then Exit Function
Next ws
End Function
The following example adds a new worksheet named myNewSheet
, if it doesn't already exist:
If Not wsExists("myNewSheet") Then Sheets.Add.Name = "myNewSheet"
For Each
…Next
Statement (VBA)Exit
Statement (VBA) I made an extension to disable it on all sites. In doing so I used three techniques: pure CSS, pure JS and hybrid.
The CSS version is similar to the above solutions. The JS one goes a bit like this:
var scroll = function(e) {
// compute state
if (stopScrollX || stopScrollY) {
e.preventDefault(); // this one is the key
e.stopPropagation();
window.scroll(scrollToX, scrollToY);
}
}
document.addEventListener('mousewheel', scroll, false);
The CSS one works when one is using position: fixed elements and let the browser do the scrolling. The JS one is needed when some other JS depends on window (e.g events), which would get blocked by the previous CSS (since it makes the body scroll instead of the window), and works by stopping event propagation at the edges, but needs to synthesize the scrolling of the non-edge component; the downside is that it prevents some types of scrolling to happen (those do work with the CSS one). The hybrid one tries to take a mixed approach by selectively disabling directional overflow (CSS) when scrolling reaches an edge (JS), and in theory could work in both cases, but doesn't quite currently as it has some leeway at the limit.
So depending on the implementations of one's website, one needs to either take one approach or the other.
See here if one wants more details: https://github.com/lloeki/unelastic
You can index and use a negative sign to drop the 3rd column:
data[,-3]
Or you can list only the first 2 columns:
data[,c("c1", "c2")]
data[,1:2]
Don't forget the comma and referencing data frames works like this: data[row,column]
From this post:
To get the entire PC CPU and Memory usage:
using System.Diagnostics;
Then declare globally:
private PerformanceCounter theCPUCounter =
new PerformanceCounter("Processor", "% Processor Time", "_Total");
Then to get the CPU time, simply call the NextValue()
method:
this.theCPUCounter.NextValue();
This will get you the CPU usage
As for memory usage, same thing applies I believe:
private PerformanceCounter theMemCounter =
new PerformanceCounter("Memory", "Available MBytes");
Then to get the memory usage, simply call the NextValue()
method:
this.theMemCounter.NextValue();
For a specific process CPU and Memory usage:
private PerformanceCounter theCPUCounter =
new PerformanceCounter("Process", "% Processor Time",
Process.GetCurrentProcess().ProcessName);
where Process.GetCurrentProcess().ProcessName
is the process name you wish to get the information about.
private PerformanceCounter theMemCounter =
new PerformanceCounter("Process", "Working Set",
Process.GetCurrentProcess().ProcessName);
where Process.GetCurrentProcess().ProcessName
is the process name you wish to get the information about.
Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?
To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters
The difference between Processor\% Processor Time
and Process\% Processor Time
is Processor
is from the PC itself and Process
is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters
An alternative to using the Performance Counter
Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.
Instance variables or fields, along with static variables, are assigned default values based on the variable type:
0
\u0000
or 0
0.0
false
null
Just want to clarify that local variables (ie. declared in block, eg. method, for loop, while loop, try-catch, etc.) are not initialized to default values and must be explicitly initialized.
To remove untracked files / directories do:
git clean -fdx
-f - force
-d - directories too
-x - remove ignored files too ( don't use this if you don't want to remove ignored files)
Use with Caution!
These commands can permanently delete arbitrary files, that you havn't thought of at first. Please double check and read all the comments below this answer and the --help section, etc., so to know all details to fine-tune your commands and surely get the expected result.
If your project has been set up as a PCL forms project (and very likely as Shared Forms as well but I haven't tried that) there is a class App.cs that looks like this:
public class App
{
public static Page GetMainPage ()
{
AuditorDB.Model.Extensions.AutoTimestamp = true;
return new NavigationPage (new LoginPage ());
}
}
you can modify the GetMainPage
method to return a new TabbedPaged or some other page you have defined in the project
From there on you can add commands or event handlers to execute code and do
// to show OtherPage and be able to go back
Navigation.PushAsync(new OtherPage());
// to show AnotherPage and not have a Back button
Navigation.PushModalAsync(new AnotherPage());
// to go back one step on the navigation stack
Navigation.PopAsync();
If, like me, you've come to this topic via Razor components as you're learning Blazor, then you'll find you need to think a little more outside of the box to solve this problem. It's a bit of a minefield if (also like me) Blazor is your first forray into the MVC-type world, as the documentation isn't as helpful for such 'menial' tasks.
So, at the time of writing, you cannot achieve this using vanilla Blazor/Razor without embedding an MVC controller to handle the file download part an example of which is as below:
using Microsoft.AspNetCore.Mvc;
using Microsoft.Net.Http.Headers;
[Route("api/[controller]")]
[ApiController]
public class FileHandlingController : ControllerBase
{
[HttpGet]
public FileContentResult Download(int attachmentId)
{
TaskAttachment taskFile = null;
if (attachmentId > 0)
{
// taskFile = <your code to get the file>
// which assumes it's an object with relevant properties as required below
if (taskFile != null)
{
var cd = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
{
FileNameStar = taskFile.Filename
};
Response.Headers.Add(HeaderNames.ContentDisposition, cd.ToString());
}
}
return new FileContentResult(taskFile?.FileData, taskFile?.FileContentType);
}
}
Next, make sure your application startup (Startup.cs) is configured to correctly use MVC and has the following line present (add it if not):
services.AddMvc();
.. and then finally modify your component to link to the controller, for example (iterative based example using a custom class):
<tbody>
@foreach (var attachment in yourAttachments)
{
<tr>
<td><a href="api/[email protected]" target="_blank">@attachment.Filename</a> </td>
<td>@attachment.CreatedUser</td>
<td>@attachment.Created?.ToString("dd MMM yyyy")</td>
<td><ul><li class="oi oi-circle-x delete-attachment"></li></ul></td>
</tr>
}
</tbody>
Hopefully this helps anyone who struggled (like me!) to get an appropriate answer to this seemingly simple question in the realms of Blazor…!
It is a little complicated, but you can draw all the objects by the following code:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
from itertools import product, combinations
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_aspect("equal")
# draw cube
r = [-1, 1]
for s, e in combinations(np.array(list(product(r, r, r))), 2):
if np.sum(np.abs(s-e)) == r[1]-r[0]:
ax.plot3D(*zip(s, e), color="b")
# draw sphere
u, v = np.mgrid[0:2*np.pi:20j, 0:np.pi:10j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
ax.plot_wireframe(x, y, z, color="r")
# draw a point
ax.scatter([0], [0], [0], color="g", s=100)
# draw a vector
from matplotlib.patches import FancyArrowPatch
from mpl_toolkits.mplot3d import proj3d
class Arrow3D(FancyArrowPatch):
def __init__(self, xs, ys, zs, *args, **kwargs):
FancyArrowPatch.__init__(self, (0, 0), (0, 0), *args, **kwargs)
self._verts3d = xs, ys, zs
def draw(self, renderer):
xs3d, ys3d, zs3d = self._verts3d
xs, ys, zs = proj3d.proj_transform(xs3d, ys3d, zs3d, renderer.M)
self.set_positions((xs[0], ys[0]), (xs[1], ys[1]))
FancyArrowPatch.draw(self, renderer)
a = Arrow3D([0, 1], [0, 1], [0, 1], mutation_scale=20,
lw=1, arrowstyle="-|>", color="k")
ax.add_artist(a)
plt.show()
What is happening is that stock_list.toArray()
is creating an Object[]
rather than a String[]
and hence the typecast is failing1.
The correct code would be:
String [] stockArr = stockList.toArray(new String[stockList.size()]);
or even
String [] stockArr = stockList.toArray(new String[0]);
For more details, refer to the javadocs for the two overloads of List.toArray
.
The latter version uses the zero-length array to determine the type of the result array. (Surprisingly, it is faster to do this than to preallocate ... at least, for recent Java releases. See https://stackoverflow.com/a/4042464/139985 for details.)
From a technical perspective, the reason for this API behavior / design is that an implementation of the List<T>.toArray()
method has no information of what the <T>
is at runtime. All it knows is that the raw element type is Object
. By contrast, in the other case, the array parameter gives the base type of the array. (If the supplied array is big enough to hold the list elements, it is used. Otherwise a new array of the same type and a larger size is allocated and returned as the result.)
1 - In Java, an Object[]
is not assignment compatible with a String[]
. If it was, then you could do this:
Object[] objects = new Object[]{new Cat("fluffy")};
Dog[] dogs = (Dog[]) objects;
Dog d = dogs[0]; // Huh???
This is clearly nonsense, and that is why array types are not generally assignment compatible.
I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh
let's use imshow
:
import numpy as np
import matplotlib.pyplot as plt
H = np.array([[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12],
[13, 14, 15, 16]]) # added some commas and array creation code
fig = plt.figure(figsize=(6, 3.2))
ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')
cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()
As the other answers state:
count
will perform an SQL COUNT
querylength
will calculate the length of the resulting arraysize
will try to pick the most appropriate of the two to avoid excessive queriesBut there is one more thing. We noticed a case where size
acts differently to count
/length
altogether, and I thought I'd share it since it is rare enough to be overlooked.
If you use a :counter_cache
on a has_many
association, size
will use the cached count directly, and not make an extra query at all.
class Image < ActiveRecord::Base
belongs_to :product, counter_cache: true
end
class Product < ActiveRecord::Base
has_many :images
end
> product = Product.first # query, load product into memory
> product.images.size # no query, reads the :images_count column
> product.images.count # query, SQL COUNT
> product.images.length # query, loads images into memory
This behaviour is documented in the Rails Guides, but I either missed it the first time or forgot about it.
Using dplyr you can:
df <- df %>% dplyr:: select(grep("ABC", names(df)), grep("XYZ", names(df)))
Try this:
& "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe" PCNAME
To PowerShell a string "..." is just a string and PowerShell evaluates it by echoing it to the screen. To get PowerShell to execute the command whose name is in a string, you use the call operator &
.
I used this:
jQuery.validator.addMethod("phoneUS", function(phone_number, element) {
phone_number = phone_number.replace(/\s+/g, "");
return this.optional(element) || phone_number.length > 9 &&
phone_number.match(/^(1-?)?(\([2-9]\d{2}\)|[2-9]\d{2})-?[2-9]\d{2}-?\d{4}$/);
}, "Please specify a valid phone number");
For a single file you can use -O
instead of -o filename
to use the last segment of the URL path as the filename. Example:
curl http://example.com/folder/big-file.iso -O
will save the results to a new file named big-file.iso in the current folder. In this way it works similar to wget but allows you to specify other curl options that are not available when using wget.
you can use below command,
mongod --dbpath=D:\home\mongodata
where D:\home\mongodata is the data storage path
Please find below example using Selenium "until.stalenessOf" and Jasmine assertion. It returns true when element is no longer attached to the DOM.
const { Builder, By, Key, until } = require('selenium-webdriver');
it('should not find element', async () => {
const waitTime = 10000;
const el = await driver.wait( until.elementLocated(By.css('#my-id')), waitTime);
const isRemoved = await driver.wait(until.stalenessOf(el), waitTime);
expect(isRemoved).toBe(true);
});

It depends on what encoding you use. If you want to convert utf-8 encoded hex to string, use this:
function fromHex(hex,str){
try{
str = decodeURIComponent(hex.replace(/(..)/g,'%$1'))
}
catch(e){
str = hex
console.log('invalid hex input: ' + hex)
}
return str
}
For the other direction use this:
function toHex(str,hex){
try{
hex = unescape(encodeURIComponent(str))
.split('').map(function(v){
return v.charCodeAt(0).toString(16)
}).join('')
}
catch(e){
hex = str
console.log('invalid text input: ' + str)
}
return hex
}
You could do something like this:
htmlComponent.ts
htmlVariable: string = "<b>Some html.</b>";
//this is html in TypeScript code that you need to display
htmlComponent.html
<div [innerHtml]="htmlVariable"></div>
//this is how you display html code from TypeScript in your html
You could use PHP's array_reduce as well,
$a = ['Name' => 'Last Name'];
function acc($acc,$k)use($a){ return $acc .= $k.":".$a[$k].",";}
$imploded = array_reduce(array_keys($a), "acc");
Answering the question: to remove the last character, just use:string = string[:-1]
.
If you want to remove the last '\' if there is one (or if there is more than one):
while string[-1]=='\\':
string = string[:-1]
If it's a path, then use the os.path
functions:
dir = "dir1\\dir2\\file.jpg\\" #I'm using windows by the way
os.path.dirname(dir)
although I would 'add' a slash in the end to prevent missing the filename in case there's no slash at the end of the original string:
dir = "dir1\\dir2\\file.jpg"
os.path.dirname(dir + "\\")
When using abspath, (if the path isn't absolute I guess,) will add the current working directory to the path.
os.path.abspath(dir)
using only grep:
grep -n "text to find" file.ext | grep -Po '^[^:]+'
Maybe this is what you want?
echo foo > test.txt
echo. >> test.txt
echo bar >> test.txt
results in the following within test.txt:
foo
bar
... Could not load file or assembly 'X' or one of its dependencies ...
Most likely it fails to load another dependency.
you could try to check the dependencies with a dependency walker.
I.e: https://www.dependencywalker.com/
Also check your build configuration (x86 / 64)
Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.
See here: Detected DLLs that are from the internet and "blocked" by CASPOL
Since answers posted only allow you to query the active network, here's how to get NetworkInfo
for any network, not only the active one (for example Wifi network) (sorry, Kotlin code ahead)
(getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager).run {
allNetworks.find { getNetworkInfo(it).type == ConnectivityManager.TYPE_WIFI }?.let { network -> getNetworkInfo(network) }
// getNetworkInfo(ConnectivityManager.TYPE_WIFI).isAvailable // This is the deprecated API pre-21
}
This requires API 21 or higher and the permission android.permission.ACCESS_NETWORK_STATE
Like this:
int main()
{
int arr[2][5] =
{
{1,8,12,20,25},
{5,9,13,24,26}
};
}
This should be covered by your C++ textbook: which one are you using?
Anyway, better, consider using std::vector
or some ready-made matrix class e.g. from Boost.
PROBLEM: "Back" text in the navigation bar can not be replaced.
REASON: "Back" label is set in the navigation bar after pushing a view because the .title attribute in the parent view controller was set to nil (or not initialised).
ONE SOLUTION: If you set the self.title="Whatever..." you will see that instead of "Back" will appear "Whatever..." after pushing new view controller.
Yes, they are same for just int
and different for int*
You are correct in that your list contains a reference to the original dictionary.
a.append(b.copy())
should do the trick.
Bear in mind that this makes a shallow copy. An alternative is to use copy.deepcopy(b)
, which makes a deep copy.
The raw.githubusercontent.com
domain is used to serve unprocessed versions of files stored in GitHub repositories. If you browse to a file on GitHub and then click the Raw link, that's where you'll go.
The URL in your question references the install
file in the master
branch of the Homebrew/install
repository. The rest of that command just retrieves the file and runs ruby
on its contents.
To enable Push Notification for your iOS app, you will need to create and upload the Apple Push Notification Certificate (.pem file) to us so we will be able to connect to Apple Push Server on your behalf.
(Updated version with updated screen shots Here)
Step 1: Login to iOS Provisioning Portal, click "Certificates" on the left navigation bar. Then, click "+" button.
Step 2: Select Apple Push Notification service SSL (Production) option under Distribution section, then click "Continue" button.
Step 3: Select the App ID you want to use for your BYO app (How to Create An App ID), then click "Continue" to go to next step.
Step 4: Follow the steps "About Creating a Certificate Signing Request (CSR)" to create a Certificate Signing Request.
To supplement the instruction provided by Apple. Here are some of the additional screenshots to assist you to complete the required steps:
Step 4 Supplementary Screenshot 1: Navigate to Certificate Assistant of Keychain Access on your Mac.
Step 4 Supplementary Screenshot 2: Fill in the Certificate Information. Click Continue.
Step 5: Upload the ".certSigningRequest" file which is generated in Step 4, then click "Generate" button.
Step 6: Click "Done" to finish the registration, the iOS Provisioning Portal Page will be refreshed that looks like the following screen:
Then Click "Download" button to download the certificate (.cer file) you've created just now. - Double click the downloaded file to install the certificate into Keychain Access on your Mac.
Step 7: On your Mac, go to "Keychain", look for the certificate you have just installed. If unsure which certificate is the correct one, it should start with "Apple Production IOS Push Services:" followed by your app's bundle ID.
Step 8: Expand the certificate, you should see the private key with either your name or your company name. Select both items by using the "Select" key on your keyboard, right click (or cmd-click if you use a single button mouse), choose "Export 2 items", like Below:
Then save the p12 file with name "pushcert.p12" to your Desktop - now you will be prompted to enter a password to protect it, you can either click Enter to skip the password or enter a password you desire.
Step 9: Now the most difficult part - open "Terminal" on your Mac, and run the following commands:
cd
cd Desktop
openssl pkcs12 -in pushcert.p12 -out pushcert.pem -nodes -clcerts
Step 10: Remove pushcert.p12 from Desktop to avoid mis-uploading it to Build Your Own area. Open "Terminal" on your Mac, and run the following commands:
cd
cd Desktop
rm pushcert.p12
Step 11 - NEW AWS UPDATE: Create new pushcert.p12
to submit to AWS SNS. Double click on the new pushcert.pem
, then export the one highlighed on the green only.
Credit: AWS new update
Now you have successfully created an Apple Push Notification Certificate (.p12 file)! You will need to upload this file to our Build Your Own area later on. :)
useHistory
hook:If you have React >= 16.8
and functional components you can use the useHistory
hook from react-router.
import React from 'react';
import { useHistory } from 'react-router-dom';
const YourComponent = () => {
const history = useHistory();
const handleClick = () => {
history.push("/path/to/push");
}
return (
<div>
<button onClick={handleClick} type="button" />
</div>
);
}
export default YourComponent;
withRouter
HOC:As @ambar mentioned in the comments, React-router has changed their code base since their V4. Here are the documentations - official, withRouter
import React, { Component } from 'react';
import { withRouter } from "react-router-dom";
class YourComponent extends Component {
handleClick = () => {
this.props.history.push("path/to/push");
}
render() {
return (
<div>
<button onClick={this.handleClick} type="button">
</div>
);
};
}
export default withRouter(YourComponent);
browserHistory
You can achieve this functionality using react-router BrowserHistory
. Code below:
import React, { Component } from 'react';
import { browserHistory } from 'react-router';
export default class YourComponent extends Component {
handleClick = () => {
browserHistory.push('/login');
};
render() {
return (
<div>
<button onClick={this.handleClick} type="button">
</div>
);
};
}
connected-react-router
If you have connected your component with redux, and have configured connected-react-router all you have to do is
this.props.history.push("/new/url");
ie, you don't need withRouter
HOC to inject history
to the component props.
// reducers.js
import { combineReducers } from 'redux';
import { connectRouter } from 'connected-react-router';
export default (history) => combineReducers({
router: connectRouter(history),
... // rest of your reducers
});
// configureStore.js
import { createBrowserHistory } from 'history';
import { applyMiddleware, compose, createStore } from 'redux';
import { routerMiddleware } from 'connected-react-router';
import createRootReducer from './reducers';
...
export const history = createBrowserHistory();
export default function configureStore(preloadedState) {
const store = createStore(
createRootReducer(history), // root reducer with router state
preloadedState,
compose(
applyMiddleware(
routerMiddleware(history), // for dispatching history actions
// ... other middlewares ...
),
),
);
return store;
}
// set up other redux requirements like for eg. in index.js
import { Provider } from 'react-redux';
import { Route, Switch } from 'react-router';
import { ConnectedRouter } from 'connected-react-router';
import configureStore, { history } from './configureStore';
...
const store = configureStore(/* provide initial state if any */)
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}>
<> { /* your usual react-router v4/v5 routing */ }
<Switch>
<Route exact path="/yourPath" component={YourComponent} />
</Switch>
</>
</ConnectedRouter>
</Provider>,
document.getElementById('root')
);
// YourComponent.js
import React, { Component } from 'react';
import { connect } from 'react-redux';
...
class YourComponent extends Component {
handleClick = () => {
this.props.history.push("path/to/push");
}
render() {
return (
<div>
<button onClick={this.handleClick} type="button">
</div>
);
}
};
}
export default connect(mapStateToProps = {}, mapDispatchToProps = {})(YourComponent);
I have XAMPP 1.8.3-0 and PHP 5.5.0 installed.
1) edit php.ini:
from
;extension=php_intl.dll
to
extension=php_intl.dll
Note: After modification, need to save the file(php.ini) as well as need to restart the Apache Server.
2) Simply copy all icu* * * *.dll files:
from
C:\xampp\php
to
C:\xampp\apache\bin
Then intl extension works!!!
Why not just
let myNumber = 213.27321;
+myNumber.toFixed(1); // => 213.3
To safely encrypt large files (>600MB) with openssl smime
you'll have to split each file into small chunks:
# Splits large file into 500MB pieces
split -b 500M -d -a 4 INPUT_FILE_NAME input.part.
# Encrypts each piece
find -maxdepth 1 -type f -name 'input.part.*' | sort | xargs -I % openssl smime -encrypt -binary -aes-256-cbc -in % -out %.enc -outform DER PUBLIC_PEM_FILE
For the sake of information, here is how to decrypt and put all pieces together:
# Decrypts each piece
find -maxdepth 1 -type f -name 'input.part.*.enc' | sort | xargs -I % openssl smime -decrypt -in % -binary -inform DEM -inkey PRIVATE_PEM_FILE -out %.dec
# Puts all together again
find -maxdepth 1 -type f -name 'input.part.*.dec' | sort | xargs cat > RESTORED_FILE_NAME
Another way to do this is to use the numpy matrix
class (rather than a numpy array) and the I
attribute. For example:
>>> m = np.matrix([[2,3],[4,5]])
>>> m.I
matrix([[-2.5, 1.5],
[ 2. , -1. ]])
If you want to disable client side validation for a form in HTML5 add a novalidate attribute to the form element. Ex:
<form method="post" action="/foo" novalidate>...</form>
See https://www.w3.org/TR/html5/sec-forms.html#element-attrdef-form-novalidate
app.component.html
<div>
<h5 style="color:#ffffff;">{{myDate | date:'fullDate'}}</h5>
</div>
app.component.ts
export class AppComponent implements OnInit {
myDate = Date.now(); //date
2,147,483,647 bytes, since the value is a signed integer (Int32). That's probably more than you'll need.
n = int(input("enter a n value:"))
d = {}
for i in range(n):
keys = input() # here i have taken keys as strings
values = int(input()) # here i have taken values as integers
d[keys] = values
print(d)
Let's add pcntl_signal
and pcntl_alarm
to the list.
With the help of those functions you can work around any set_time_limit restriction created int the php.ini or in the script.
This script for example will run for 10 seconds despite of set_time_limit(1);
(Credit goes to Sebastian Bergmanns tweet and gist:
<?php
declare(ticks = 1);
set_time_limit(1);
function foo() {
for (;;) {}
}
class Invoker_TimeoutException extends RuntimeException {}
class Invoker
{
public function invoke($callable, $timeout)
{
pcntl_signal(SIGALRM, function() { throw new Invoker_TimeoutException; }, TRUE);
pcntl_alarm($timeout);
call_user_func($callable);
}
}
try {
$invoker = new Invoker;
$invoker->invoke('foo', 1);
} catch (Exception $e) {
sleep(10);
echo "Still running despite of the timelimit";
}
EDITED MARCH 2019 now with programmatic pin color,

I needed the div to stop when it reach a certain object, so i did it like this:
var el = $('#followdeal');
var elpos_original = el.offset().top;
$(window).scroll(function(){
var elpos = el.offset().top;
var windowpos = $(window).scrollTop();
var finaldestination = windowpos;
var stophere = ( $('#filtering').offset().top ) - 170;
if(windowpos<elpos_original || windowpos>=stophere) {
finaldestination = elpos_original;
el.stop().animate({'top':10});
} else {
el.stop().animate({'top':finaldestination-elpos_original+10},500);
}
});
As a follow on, you could select "all nodes with a particular attribute" like this:
//*[@id='4']
01-Feb-2014
$date = mktime( 0, 0, 0, 2, 1, 2014 );
echo strftime( '%d %B %Y', strtotime( '+1 month', $date ) );
Use the DateTime.SpecifyKind
static method.
Creates a new DateTime object that has the same number of ticks as the specified DateTime, but is designated as either local time, Coordinated Universal Time (UTC), or neither, as indicated by the specified DateTimeKind value.
Example:
DateTime dateTime = DateTime.Now;
DateTime other = DateTime.SpecifyKind(dateTime, DateTimeKind.Utc);
Console.WriteLine(dateTime + " " + dateTime.Kind); // 6/1/2011 4:14:54 PM Local
Console.WriteLine(other + " " + other.Kind); // 6/1/2011 4:14:54 PM Utc
This is the way I've been doing this sort of stuff. Angular tends to favor declarative manipulation of the dom rather than a imperative one(at least that's the way I've been playing with it).
The markup
<table class="table">
<thead>
<tr>
<th>
<input type="checkbox"
ng-click="selectAll($event)"
ng-checked="isSelectedAll()">
</th>
<th>Title</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="e in entities" ng-class="getSelectedClass(e)">
<td>
<input type="checkbox" name="selected"
ng-checked="isSelected(e.id)"
ng-click="updateSelection($event, e.id)">
</td>
<td>{{e.title}}</td>
</tr>
</tbody>
</table>
And in the controller
var updateSelected = function(action, id) {
if (action === 'add' && $scope.selected.indexOf(id) === -1) {
$scope.selected.push(id);
}
if (action === 'remove' && $scope.selected.indexOf(id) !== -1) {
$scope.selected.splice($scope.selected.indexOf(id), 1);
}
};
$scope.updateSelection = function($event, id) {
var checkbox = $event.target;
var action = (checkbox.checked ? 'add' : 'remove');
updateSelected(action, id);
};
$scope.selectAll = function($event) {
var checkbox = $event.target;
var action = (checkbox.checked ? 'add' : 'remove');
for ( var i = 0; i < $scope.entities.length; i++) {
var entity = $scope.entities[i];
updateSelected(action, entity.id);
}
};
$scope.getSelectedClass = function(entity) {
return $scope.isSelected(entity.id) ? 'selected' : '';
};
$scope.isSelected = function(id) {
return $scope.selected.indexOf(id) >= 0;
};
//something extra I couldn't resist adding :)
$scope.isSelectedAll = function() {
return $scope.selected.length === $scope.entities.length;
};
EDIT: getSelectedClass()
expects the entire entity but it was being called with the id of the entity only, which is now corrected
The following code works:
@Override
protected synchronized void onDraw(Canvas canvas)
{
int stars = getNumStars();
float rating = getRating();
try
{
bitmapWidth = getWidth() / stars;
}
catch (Exception e)
{
bitmapWidth = getWidth();
}
float x = 0;
for (int i = 0; i < stars; i++)
{
Bitmap bitmap;
Resources res = getResources();
Paint paint = new Paint();
if ((int) rating > i)
{
bitmap = BitmapFactory.decodeResource(res, starColor);
}
else
{
bitmap = BitmapFactory.decodeResource(res, starDefault);
}
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, getHeight(), getHeight(), true);
canvas.drawBitmap(scaled, x, 0, paint);
canvas.save();
x += bitmapWidth;
}
super.onDraw(canvas);
}
Make sure that your sas.png
is marked as Build Action: Content
and Copy To Output Directory: Copy Always
in its Visual Studio Properties
...
I think the C# source code goes like this...
Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;
and XAML should be
<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0"
Name="image1" Stretch="Fill" VerticalAlignment="Top"
Source="../Bilder/sas.png"
Width="350" />
EDIT
Dynamically I think XAML would provide best way to load Images ...
<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
x:Name="MyImage"/>
where image.DataContext
is string
path.
MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";
public class MyImageSourceConverter : IValueConverter
{
public object Convert(object value_, Type targetType_,
object parameter_, System.Globalization.CultureInfo culture_)
{
return (new ImageSourceConverter()).ConvertFromString (value.ToString());
}
public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
Now as you set a different data context, Image
would be automatically loaded at runtime.
Got it. Add the following within the DataGrid.Resources section:
<DataGrid.Resources>
<Style TargetType="{x:Type dg:DataGridCell}">
<Style.Triggers>
<Trigger Property="dg:DataGridCell.IsSelected" Value="True">
<Setter Property="Background" Value="#CCDAFF" />
</Trigger>
</Style.Triggers>
</Style>
</DataGrid.Resources>
Try this:
int dayOfWeek = date.get(Calendar.DAY_OF_WEEK);
String weekday = new DateFormatSymbols().getShortWeekdays()[dayOfWeek];
Understand that .children
is a property of an Element. 1 Only Elements have .children
, and these children are all of type Element. 2
However, .childNodes
is a property of Node. .childNodes
can contain any node. 3
A concrete example would be:
let el = document.createElement("div");
el.textContent = "foo";
el.childNodes.length === 1; // Contains a Text node child.
el.children.length === 0; // No Element children.
Most of the time, you want to use .children
because generally you don't want to loop over Text or Comment nodes in your DOM manipulation.
If you do want to manipulate Text nodes, you probably want .textContent
instead. 4
1. Technically, it is an attribute of ParentNode, a mixin included by Element.
2. They are all elements because .children
is a HTMLCollection, which can only contain elements.
3. Similarly, .childNodes
can hold any node because it is a NodeList.
4. Or .innerText
. See the differences here or here.
You need to change from queue import Queue
to from multiprocessing import Queue
.
The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.
For details, you can read some source code or contact me!
Javascript will be required; for example:
$(function(){
$('[type="date"]').prop('max', function(){
return new Date().toJSON().split('T')[0];
});
});
NSIntegers are not objects, you cast them to long
, in order to match the current 64-bit architectures' definition:
NSString *inStr = [NSString stringWithFormat: @"%ld", (long)month];
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;
....
this.environment.getActiveProfiles();
You need to compile and link all your source files together:
g++ main.c function_file.c
Even when the question is regarding Java 7, I think it adds value to know that from Java 11 onward, there is a static method in Path
class that allows to do this straight away:
With all the path in one String:
Path.of("/tmp/foo");
With the path broken down in several Strings:
Path.of("/tmp","foo");
Instead of using pull-right
class, it is better to use text-right
class in the column, because pull-right
creates problems sometimes while resizing the page.
I know you said you don't care about how secure it is, but if you chose DES you might as well take AES it is the more up-to-date encryption method.
Of course "cache-breaking" techniques will get the job done, but this would not happen in the first place if the server indicated to the client that the response should not be cached. In some cases it is beneficial to cache responses, some times not. Let the server decide the correct lifetime of the data. You may want to change it later. Much easier to do from the server than from many different places in your UI code.
Of course this doesn't help if you have no control over the server.
The encrypted string had two special characters, +
and =
.
'+' sign was giving the error, so below solution worked well:
//replace + sign
encryted_string = encryted_string.Replace("+", "%2b");
//`%2b` is HTTP encoded string for **+** sign
OR
//encode special charactes
encryted_string = HttpUtility.UrlEncode(encryted_string);
//then pass it to the decryption process
...
To change the disabled
property you should use the .prop()
function.
$("input").prop('disabled', true);
$("input").prop('disabled', false);
The .prop()
function doesn't exist, but .attr()
does similar:
Set the disabled attribute.
$("input").attr('disabled','disabled');
To enable again, the proper method is to use .removeAttr()
$("input").removeAttr('disabled');
You can always rely on the actual DOM object and is probably a little faster than the other two options if you are only dealing with one element:
// assuming an event handler thus 'this'
this.disabled = true;
The advantage to using the .prop()
or .attr()
methods is that you can set the property for a bunch of selected items.
Note: In 1.6 there is a .removeProp()
method that sounds a lot like removeAttr()
, but it SHOULD NOT BE USED on native properties like 'disabled'
Excerpt from the documentation:
Note: Do not use this method to remove native properties such as checked, disabled, or selected. This will remove the property completely and, once removed, cannot be added again to element. Use .prop() to set these properties to false instead.
In fact, I doubt there are many legitimate uses for this method, boolean props are done in such a way that you should set them to false instead of "removing" them like their "attribute" counterparts in 1.5
To set output directory and output file format and more, try the following:
INSERT OVERWRITE [LOCAL] DIRECTORY directory1
[ROW FORMAT row_format] [STORED AS file_format]
SELECT ... FROM ...
Example:
INSERT OVERWRITE DIRECTORY '/path/to/output/dir'
ROW FORMAT DELIMITED
STORED AS PARQUET
SELECT * FROM table WHERE id > 100;
What you are describing is actually what FontAwesome is doing already. They apply the FontAwesome font-family to the ::before
pseudo element of any element that has a class that starts with "icon-".
[class^="icon-"]:before,
[class*=" icon-"]:before {
font-family: FontAwesome;
font-weight: normal;
font-style: normal;
display: inline-block;
text-decoration: inherit;
}
Then they use the pseudo element ::before
to place the icon in the element with the class. I just went to http://fortawesome.github.com/Font-Awesome/ and inspected the code to find this:
.icon-cut:before {
content: "\f0c4";
}
So if you are looking to add the icon again, you could use the ::after
element to achieve this. Or for your second part of your question, you could use the ::after
pseudo element to insert the bullet character to look like a list item. Then use absolute positioning to place it to the left, or something similar.
i:after{ content: '\2022';}
/[\W\S_]/
This creates a character class removing the word characters, space characters, and adding back the underscore character (as underscore is a "word" character). All that is left is the special characters. Capital letters represent the negation of their lowercase counterparts.
\W
will select all non "word" characters equivalent to [^a-zA-Z0-9_]
\S
will select all non "whitespace" characters equivalent to [ \t\n\r\f\v]
_
will select "_" because we negate it when using the \W
and need to add it back in
I authored (yet another) angular html5 storage service. I wanted to keep the automatic updates made possible by ngStorage
, but make digest cycles more predictable/intuitive (at least for me), add events to handle when state reloads are required, and also add sharing session storage between tabs. I modelled the API after $resource
and called it angular-stored-object
. It can be used as follows:
angular
.module('auth', ['yaacovCR.storedObject']);
angular
.module('auth')
.factory('session', session);
function session(ycr$StoredObject) {
return new ycr$StoredObject('session');
}
API is here.
Repo is here.
Hope it helps somebody!
In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.
In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.
With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.
This fixed my problem. I kept getting the console error in eclipse "Could not find com_android_vending_licensing.apk" and even though it didnt seem to effect the way my app ran, it was annoying. So going into the com_android_vending_licensing project properties and unchecking the "is library" option, building the project to produce the needed apk and then going back into the com_android_vending_licensing project properties and re checking the "is library" check box fixed the problem.
Do you want something like the given fiddle!

You could really, really, really optimize your code a lot by paying the price of creating the delegate only once (there's also no need to instantiate the class to call an static method). I've done something very similar, and I just cache a delegate to the "Run" method with the help of a helper class :-). It looks like this:
static class Indent{
public static void Run(){
// implementation
}
// other helper methods
}
static class MacroRunner {
static MacroRunner() {
BuildMacroRunnerList();
}
static void BuildMacroRunnerList() {
macroRunners = System.Reflection.Assembly.GetExecutingAssembly()
.GetTypes()
.Where(x => x.Namespace.ToUpper().Contains("MACRO"))
.Select(t => (Action)Delegate.CreateDelegate(
typeof(Action),
null,
t.GetMethod("Run", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
.ToList();
}
static List<Action> macroRunners;
public static void Run() {
foreach(var run in macroRunners)
run();
}
}
It is MUCH faster this way.
If your method signature is different from Action you could replace the type-casts and typeof from Action to any of the needed Action and Func generic types, or declare your Delegate and use it. My own implementation uses Func to pretty print objects:
static class PrettyPrinter {
static PrettyPrinter() {
BuildPrettyPrinterList();
}
static void BuildPrettyPrinterList() {
printers = System.Reflection.Assembly.GetExecutingAssembly()
.GetTypes()
.Where(x => x.Name.EndsWith("PrettyPrinter"))
.Select(t => (Func<object, string>)Delegate.CreateDelegate(
typeof(Func<object, string>),
null,
t.GetMethod("Print", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
.ToList();
}
static List<Func<object, string>> printers;
public static void Print(object obj) {
foreach(var printer in printers)
print(obj);
}
}
Use
document.getElementById('<%= txt_model_code.ClientID %>')
instead of
document.getElementById('txt_model_code')`
Also you can use onClientClick
instead of onClick
.
A little late, but here's a regex I found that returns 0 matches for empty or white spaces:
/^(?!\s*$).+/
You can test this out at regex101
Separate with commas:
http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505
or:
http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505
or:
http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505
Either way, your method signature needs to be:
@RequestMapping(value = "/GetJson", method = RequestMethod.GET)
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
//code to get results from db for those params.
}
As Chris suggests, you can do it like this:
public string GetXMLAsString(XmlDocument myxml)
{
return myxml.OuterXml;
}
Or like this:
public string GetXMLAsString(XmlDocument myxml)
{
StringWriter sw = new StringWriter();
XmlTextWriter tx = new XmlTextWriter(sw);
myxml.WriteTo(tx);
string str = sw.ToString();//
return str;
}
and if you really want to create a new XmlDocument
then do this
XmlDocument newxmlDoc= myxml
In case of OO... To say that a Given Class has and "Default" means that this Default (value) must declared acondingly an then may be usd as an Default Parameter ex:
class Pagination {
public:
int currentPage;
//...
Pagination() {
currentPage = 1;
//...
}
// your Default Pagination
static Pagination& Default() {
static Pagination pag;
return pag;
}
};
On your Method ...
shared_ptr<vector<Auditoria> >
findByFilter(Auditoria& audit, Pagination& pagination = Pagination::Default() ) {
This solutions is quite suitable since in this case, "Global default Pagination" is a single "reference" value. You will also have the power to change default values at runtime like an "gobal-level" configuration ex: user pagination navigation preferences and etc..
Top comment has a broken link to the console.log documentation for Firebug, so here is a link to the wiki article about Console. I started using it and am quite satisfied with it as an alternative to PHP's print_r().
Also of note is that Firebug gives you access to returned JSON objects even without you manually logging them:
This method take a couple more clicks to get at the data but doesn't require any additions in your actual javascript and doesn't shift your focus in Firebug out of the console (using console.log creates a link to the DOM section of firebug, forcing you to click back to console after).
For my money I'd rather click a couple more times when I want to inspect rather than mess around with the log, especially since keeps the console neat by not adding any additional cruft.

The following code works for me. I am using Swift 5
let path = Bundle.main.path(forResource: "yourJSONfileName", ofType: "json")
var jsonData = try! String(contentsOfFile: path!).data(using: .utf8)!
Then, if your Person Struct (or Class) is Decodable (and also all of its properties), you can simply do:
let person = try! JSONDecoder().decode(Person.self, from: jsonData)
I avoided all the error handling code to make the code more legible.
dynamic dynJson = JsonConvert.DeserializeObject(json);
foreach (var item in dynJson)
{
Console.WriteLine("{0} {1} {2} {3}\n", item.id, item.displayName,
item.slug, item.imageUrl);
}
or
var list = JsonConvert.DeserializeObject<List<MyItem>>(json);
public class MyItem
{
public string id;
public string displayName;
public string name;
public string slug;
public string imageUrl;
}
How about using sort
?
dir /b /s | sort
Here's an example I tested with:
dir /s /b /o:gn
d:\root0
d:\root0\root1
d:\root0\root1\folderA
d:\root0\root1\folderB
d:\root0\root1\file00.txt
d:\root0\root1\file01.txt
d:\root0\root1\folderA\fileA00.txt
d:\root0\root1\folderA\fileA01.txt
d:\root0\root1\folderB\fileB00.txt
d:\root0\root1\folderB\fileB01.txt
dir /s /b | sort
d:\root0
d:\root0\root1
d:\root0\root1\file00.txt
d:\root0\root1\file01.txt
d:\root0\root1\folderA
d:\root0\root1\folderA\fileA00.txt
d:\root0\root1\folderA\fileA01.txt
d:\root0\root1\folderB
d:\root0\root1\folderB\fileB00.txt
d:\root0\root1\folderB\fileB01.txt
To just get directories, use the /A:D
parameter:
dir /a:d /s /b | sort
Is the image file ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg in your static
directory? If you move it to your static directory and update your HTML as such:
<img src="/static/ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg">
It should work.
Also, it is worth noting, there is a better way to structure this.
File structure:
app.py
static
|----ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg
templates
|----index.html
app.py
from flask import Flask, render_template, url_for
app = Flask(__name__)
@app.route('/index', methods=['GET', 'POST'])
def lionel():
return render_template('index.html')
if __name__ == '__main__':
app.run()
templates/index.html
<html>
<head>
</head>
<body>
<h1>Hi Lionel Messi</h1>
<img src="{{url_for('static', filename='ayrton_senna_movie_wallpaper_by_bashgfx-d4cm6x6.jpg')}}" />
</body>
</html>
Doing it this way ensures that you are not hard-coding a URL path for your static assets.
I faced the same issue. I had missed the forms module import tag in the app.module.ts
import { FormsModule } from '@angular/forms';
@NgModule({
imports: [BrowserModule,
FormsModule
],
myprocess.out &
would run the process in background using a subshell. If the current shell is terminated (say by logout), all subshells are also terminated so the background process would also be terminated. The nohup command ignores the HUP
signal and thus even if the current shell is terminated, the subshell and myprocess.out
would continue to run in the background. Another difference is that &
alone doesn't redirect the stdout/stderr so if there are any output or error, those are displayed on the terminal. nohup on the other hand redirect the stdout/stderr to nohup.out
or $HOME/nohup.out
.
In my case I did a wrong modification in the image.
I was able to find the problem checking the image shape.
print img.shape
As of 2016, you can do this more simply than in any of the answers already given:
$('#myChosenBox').val();
where "myChosenBox" is the id of the original select input. Or, in the change event:
$('#myChosenBox').on('change', function(e, params) {
alert(e.target.value); // OR
alert(this.value); // OR
alert(params.selected); // also in Panagiotis Kousaris' answer
}
In the Chosen doc, in the section near the bottom of the page on triggering events, it says "Chosen triggers a number of standard and custom events on the original select field." One of those standard events is the change event, so you can use it in the same way as you would with a standard select input. You don't have to mess around with using Chosen's applied classes as selectors if you don't want to. (For the change
event, that is. Other events are often a different matter.)
In Bootstrap 3, .form-control
(the class you give your inputs) has a width of 100%, which allows you to wrap them into col-lg-X divs for arrangement. Example from the docs:
<div class="row">
<div class="col-lg-2">
<input type="text" class="form-control" placeholder=".col-lg-2">
</div>
<div class="col-lg-3">
<input type="text" class="form-control" placeholder=".col-lg-3">
</div>
<div class="col-lg-4">
<input type="text" class="form-control" placeholder=".col-lg-4">
</div>
</div>
See under Column sizing.
It's a bit different than in Bootstrap 2.3.2, but you get used to it quickly.
This command returns count of commits grouped by committers:
git shortlog -s
Output:
14 John lennon
9 Janis Joplin
You may want to know that the -s
argument is the contraction form of --summary
.
you can just use
ls > filenames.txt
(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd
to go to that folder first, or you can ls ~/docs > filenames.txt
GitHub's support determined the root of the issue right away: Two-factor authorization.
To use GitHub over the shell with https, create an OAuth token. As the page notes, I did have to remove my username and password credentials from Keychain but with osx-keychain
in place, the token is stored as the password and things work exactly as they would over https without two-factor authorization in place.
Another js alternative:
fontsize = function () {
var fontSize = $("#container").width() * 0.10; // 10% of container width
$("#container h1").css('font-size', fontSize);
};
$(window).resize(fontsize);
$(document).ready(fontsize);
Or as stated in torazaburo's answer you could use svg. I put together a simple example as a proof of concept:
<div id="container">
<svg width="100%" height="100%" viewBox="0 0 13 15">
<text x="0" y="13">X</text>
</svg>
</div>
One more method is to Define the Layout inside the View:
@{
Layout = "~/Views/Shared/_MyAdminLayout.cshtml";
}
More Ways to do, can be found here, hope this helps someone.
You might want to try kt. It's also quite faster than the bundled kafka-topics
.
This is the current most complete info description you can get out of a topic with kt:
kt topic -brokers localhost:9092 -filter my_topic_name -partitions -leaders -replicas
It also outputs as JSON, so you can pipe it to jq
for further flexibility.
If you are using the table interface you can type in NULL (all caps)
otherwise you can run an update statement where you could:
Update table set ColumnName = NULL where [Filter for record here]
fill_parent
:
A component is arranged layout for the fill_parent
will be mandatory to expand to fill the layout unit members, as much as possible in the space. This is consistent with the dockstyle property of the Windows control. A top set layout or control to fill_parent
will force it to take up the entire screen.
wrap_content
Set up a view of the size of wrap_content
will be forced to view is expanded to show all the content. The TextView and ImageView controls, for example, is set to wrap_content
will display its entire internal text and image. Layout elements will change the size according to the content. Set up a view of the size of Autosize attribute wrap_content
roughly equivalent to set a Windows control for True.

you create the Selector like below.
1.
UIBarButtonItem(
title: "Some Title",
style: UIBarButtonItemStyle.Done,
target: self,
action: "flatButtonPressed"
)
2.
flatButton.addTarget(self, action: "flatButtonPressed:", forControlEvents: UIControlEvents.TouchUpInside)
Take note that the @selector syntax is gone and replaced with a simple String naming the method to call. There’s one area where we can all agree the verbosity got in the way. Of course, if we declared that there is a target method called flatButtonPressed: we better write one:
func flatButtonPressed(sender: AnyObject) {
NSLog("flatButtonPressed")
}
set the timer:
var timer = NSTimer.scheduledTimerWithTimeInterval(1.0,
target: self,
selector: Selector("flatButtonPressed"),
userInfo: userInfo,
repeats: true)
let mainLoop = NSRunLoop.mainRunLoop() //1
mainLoop.addTimer(timer, forMode: NSDefaultRunLoopMode) //2 this two line is optinal
In order to be complete, here’s the flatButtonPressed
func flatButtonPressed(timer: NSTimer) {
}

For me it was having a file called ~/.editorconfig that was overriding my tab settings. I removed that (surely that will bite me again someday) but it fixed my pycharm issue
Another possibility is to use bit sets, for which there is at least one package or you can use the built-in big package. In this case, basically you need to define a way to convert your object to an index.
Maybe this is what you mean to do:
import random
x = 0
z = input('Please Enter an integer: ')
z = int(z) # you need to capture the result of the expressioin: int(z) and assign it backk to z
def main():
for i in range(x,z):
n1 = random.randrange(1,3)
n2 = random.randrange(1,3)
t1 = n1+n2
print('{0}+{1}={2}'.format(n1,n2,t1))
main()
Here's a link on the range() function: http://docs.python.org/release/1.5.1p1/tut/range.html
Javascript Keycodes
Except this detail Colin & Tod's answer is working.
Taking advantage of @skip405's answer, I've made a Sass mixin for it:
@mixin inline-block-lr($container,$left,$right){
#{$container}{
text-align: justify;
&:after{
content: '';
display: inline-block;
width: 100%;
height: 0;
font-size:0;
line-height:0;
}
}
#{$left} {
display: inline-block;
vertical-align: middle;
}
#{$right} {
display: inline-block;
vertical-align: middle;
}
}
It accepts 3 parameters. The container, the left and the right element. For example, to fit the question, you could use it like this:
@include inline-block-lr('header', 'h1', 'nav');
Starting an Activity is not the right approach for this behavior. Instead have your BroadcastReceiver use an intent to start a Service which can continue to run as long as possible. (See http://developer.android.com/reference/android/app/Service.html#ProcessLifecycle)
See also Persistent service
Anyone who wants to do a deep copy (e.g. if your array contains objects) can use:
let arrCopy = JSON.parse(JSON.stringify(arr))
Then you can sort arrCopy
without changing arr
.
arrCopy.sort((obj1, obj2) => obj1.id > obj2.id)
Please note: this can be slow for very large arrays.
Tensorflow upgrade -Python3
>> pip3 install --upgrade tensorflow --user

Upgrade grpcio
>> pip3 install --upgrade grpcio --user
I had a similar problem. As you increase the line-height the space above the text increases. It's not padding but it will affect the vertical space between content. I found that adding a -ve top margin seemed to do the trick. It had to be done for all of the different instances of line-height and it varies with font-family too. Maybe this is something which designers need to be more aware of when passing design requirements (?) So for a particular instance of font-family and line-height:
h1 {
font-family: 'Garamond Premier Pro Regular';
font-size: 24px;
color: #001230;
line-height: 29px;
margin-top: -5px; /* CORRECTION FOR LINE-HEIGHT */
}
I had almost just as same error with my Ruby on Rails application running postgresql(mac). This worked for me:

I tried several jquery based custom select with images, but none worked in responsive layouts. Finally i came across Bootstrap-Select. After some modifications i was able to produce this code.
If you need to send the FULL model to the controller, you first need the model to be available to your javascript code.
In our app, we do this with an extension method:
public static class JsonExtensions
{
public static string ToJson(this Object obj)
{
return new JavaScriptSerializer().Serialize(obj);
}
}
On the view, we use it to render the model:
<script type="javascript">
var model = <%= Model.ToJson() %>
</script>
You can then pass the model variable into your $.ajax call.
You can use this:
addedDate = datetime.now().replace(microsecond=0)

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.
The missing piece you've been looking for is to create an if
statement. This allows for you to toggle your text.
JSFiddle: http://jsfiddle.net/8u2jF/
Javascript:
var status = "less";
function toggleText()
{
var text="Here is some text that I want added to the HTML file";
if (status == "less") {
document.getElementById("textArea").innerHTML=text;
document.getElementById("toggleButton").innerText = "See Less";
status = "more";
} else if (status == "more") {
document.getElementById("textArea").innerHTML = "";
document.getElementById("toggleButton").innerText = "See More";
status = "less"
}
}

Dispatching an action within a reducer is an anti-pattern. Your reducer should be without side effects, simply digesting the action payload and returning a new state object. Adding listeners and dispatching actions within the reducer can lead to chained actions and other side effects.
Sounds like your initialized AudioElement
class and the event listener belong within a component rather than in state. Within the event listener you can dispatch an action, which will update progress
in state.
You can either initialize the AudioElement
class object in a new React component or just convert that class to a React component.
class MyAudioPlayer extends React.Component {
constructor(props) {
super(props);
this.player = new AudioElement('test.mp3');
this.player.audio.ontimeupdate = this.updateProgress;
}
updateProgress () {
// Dispatch action to reducer with updated progress.
// You might want to actually send the current time and do the
// calculation from within the reducer.
this.props.updateProgressAction();
}
render () {
// Render the audio player controls, progress bar, whatever else
return <p>Progress: {this.props.progress}</p>;
}
}
class MyContainer extends React.Component {
render() {
return <MyAudioPlayer updateProgress={this.props.updateProgress} />
}
}
function mapStateToProps (state) { return {}; }
return connect(mapStateToProps, {
updateProgressAction
})(MyContainer);
Note that the updateProgressAction
is automatically wrapped with dispatch
so you don't need to call dispatch directly.

This is Better Code
Take a look at PEP-238: Changing the Division Operator
The // operator will be available to request floor division unambiguously.
You could subscribe for the .click event for the links and change the contents of the div using the .html
method:
$('.click').click(function() {
// get the contents of the link that was clicked
var linkText = $(this).text();
// replace the contents of the div with the link text
$('#content-container').html(linkText);
// cancel the default action of the link by returning false
return false;
});
Note however that if you replace the contents of this div the click handler that you have assigned will be destroyed. If you intend to inject some new DOM elements inside the div for which you need to attach event handlers, this attachments should be performed inside the .click handler after inserting the new contents. If the original selector of the event is preserved you may also take a look at the .delegate
method to attach the handler.
Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.
If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.
Yes, T-SQL can feel extremely primitive at times, and it is things like these that often times push me to doing a lot of my logic in my language of choice (such as C#).
However, when you absolutely need to do some of these things in SQL for performance reasons, then your best bet is to create functions to house these "algorithms."
Take a look at this article. He offers up quite a few handy SQL functions along these lines that I think will help you.

If i go by Grodriguez's answer
System.out.println("" + value);
value = value.setScale(0, BigDecimal.ROUND_HALF_UP);
System.out.println("" + value);
This is the output
100.23 -> 100
100.77 -> 101
Which isn't quite what i want, so i ended up doing this..
System.out.println("" + value);
value = value.setScale(0, BigDecimal.ROUND_HALF_UP);
value = value.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("" + value);
This is what i get
100.23 -> 100.00
100.77 -> 101.00
This solves my problem for now .. : ) Thank you all.
This issue also occur if you do an upgrade to you cordova installation.
Check if your log error has something like:
Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting) <-------------
ANDROID_HOME=/{path}/android-sdk-linux (DEPRECATED)
Using Android SDK: /usr/lib/android-sdk
Starting a Gradle Daemon (subsequent builds will be faster)
In such case, just change ANDROID_HOME
to ANDROID_SDK_ROOT
in your ~/.bashrc
or similar config file.
Where before was:
export ANDROID_HOME="/{path}/android-sdk-linux"
Now is:
export ANDROID_SDK_ROOT="/{path}/android-sdk-linux"
Don't forget source it: $ . ~/.bashrc
after edition.
You shouldn't overload the templates with complex logic, it's a bad practice. Remember to always keep it simple!
The better approach would be to extract this logic into reusable function on your $rootScope
:
.run(function ($rootScope) {
$rootScope.inArray = function (item, array) {
return (-1 !== array.indexOf(item));
};
})
Then, use it in your template:
<li ng-class="{approved: inArray(jobSet, selectedForApproval)}"></li>
I think everyone will agree that this example is much more readable and maintainable.
objectframe.contentWindow.Reset()
you need reference to the top level element in the frame first.
I'll never easily remember these cryptic command modifiers so I took the top answer and turned it into a function in my ~/.bashrc
file:
cgrep() {
# For files that are arrays 10's of thousands of characters print.
# Use cpgrep to print 30 characters before and after search patttern.
if [ $# -eq 2 ] ; then
# Format was 'cgrep "search string" /path/to/filename'
grep -o -P ".{0,30}$1.{0,30}" "$2"
else
# Format was 'cat /path/to/filename | cgrep "search string"
grep -o -P ".{0,30}$1.{0,30}"
fi
} # cgrep()
Here's what it looks like in action:
$ ll /tmp/rick/scp.Mf7UdS/Mf7UdS.Source
-rw-r--r-- 1 rick rick 25780 Jul 3 19:05 /tmp/rick/scp.Mf7UdS/Mf7UdS.Source

1:43:30.3540244000 /mnt/e/bin/Link to iconic S -rwxrwxrwx 777 rick 1000 ri
The file in question is one continuous 25K line and it is hopeless to find what you are looking for using regular grep
.
Notice the two different ways you can call cgrep
that parallels grep
method.
There is a "niftier" way of creating the function where "$2" is only passed when set which would save 4 lines of code. I don't have it handy though. Something like ${parm2} $parm2
. If I find it I'll revise the function and this answer.
Two possible situations :
Your company uses a proxy to connect to the public Maven repository. Then ask someone in your company what the IP address of the proxy is then put it in your settings.xml file
Your company has its/their own Maven repository/ies (Nexus repository for example). Then ask someone in your company what the Nexus repository is then put it in your pom.xml or in your settings.xml. See Adding maven nexus repo to my pom.xml and https://maven.apache.org/guides/mini/guide-multiple-repositories.html
You can use a FileReader
object to read text file here is example code:
<div id="page-wrapper">
<h1>Text File Reader</h1>
<div>
Select a text file:
<input type="file" id="fileInput">
</div>
<pre id="fileDisplayArea"><pre>
</div>
<script>
window.onload = function() {
var fileInput = document.getElementById('fileInput');
var fileDisplayArea = document.getElementById('fileDisplayArea');
fileInput.addEventListener('change', function(e) {
var file = fileInput.files[0];
var textType = /text.*/;
if (file.type.match(textType)) {
var reader = new FileReader();
reader.onload = function(e) {
fileDisplayArea.innerText = reader.result;
}
reader.readAsText(file);
} else {
fileDisplayArea.innerText = "File not supported!"
}
});
}
</script>
Here is the codepen demo
If you have a fixed file to read every time your application load then you can use this code :
<script>
var fileDisplayArea = document.getElementById('fileDisplayArea');
function readTextFile(file)
{
var rawFile = new XMLHttpRequest();
rawFile.open("GET", file, false);
rawFile.onreadystatechange = function ()
{
if(rawFile.readyState === 4)
{
if(rawFile.status === 200 || rawFile.status == 0)
{
var allText = rawFile.responseText;
fileDisplayArea.innerText = allText
}
}
}
rawFile.send(null);
}
readTextFile("file:///C:/your/path/to/file.txt");
</script>
It seems like you need to use __init__
in Python if you want to correctly initialize mutable attributes of your instances.
See the following example:
>>> class EvilTest(object):
... attr = []
...
>>> evil_test1 = EvilTest()
>>> evil_test2 = EvilTest()
>>> evil_test1.attr.append('strange')
>>>
>>> print "This is evil:", evil_test1.attr, evil_test2.attr
This is evil: ['strange'] ['strange']
>>>
>>>
>>> class GoodTest(object):
... def __init__(self):
... self.attr = []
...
>>> good_test1 = GoodTest()
>>> good_test2 = GoodTest()
>>> good_test1.attr.append('strange')
>>>
>>> print "This is good:", good_test1.attr, good_test2.attr
This is good: ['strange'] []
This is quite different in Java where each attribute is automatically initialized with a new value:
import java.util.ArrayList;
import java.lang.String;
class SimpleTest
{
public ArrayList<String> attr = new ArrayList<String>();
}
class Main
{
public static void main(String [] args)
{
SimpleTest t1 = new SimpleTest();
SimpleTest t2 = new SimpleTest();
t1.attr.add("strange");
System.out.println(t1.attr + " " + t2.attr);
}
}
produces an output we intuitively expect:
[strange] []
But if you declare attr
as static
, it will act like Python:
[strange] [strange]
As previously answered here, String
instances are immutable. StringBuffer
and StringBuilder
are mutable and suitable for such a purpose whether you need to be thread safe or not.
There is however a way to modify a String but I would never recommend it because it is unsafe, unreliable and it can can be considered as cheating : you can use reflection to modify the inner char
array the String object contains. Reflection allows you to access fields and methods that are normally hidden in the current scope (private methods or fields from another class...).
public static void main(String[] args) {
String text = "This is a test";
try {
//String.value is the array of char (char[])
//that contains the text of the String
Field valueField = String.class.getDeclaredField("value");
//String.value is a private variable so it must be set as accessible
//to read and/or to modify its value
valueField.setAccessible(true);
//now we get the array the String instance is actually using
char[] value = (char[])valueField.get(text);
//The 13rd character is the "s" of the word "Test"
value[12]='x';
//We display the string which should be "This is a text"
System.out.println(text);
} catch (NoSuchFieldException | SecurityException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
Several of these things did not work for me... however, this did. Might help someone else in the future. Here is the CSS:
.img-area {
display: block;
padding: 0px 0 0 0px;
text-indent: 0;
width: 100%;
background-size: 100% 95%;
background-repeat: no-repeat;
background-image: url("https://yourimage.png");
}
Let's say the name of the parameter is "Id" in your SQL stored procedure, and the C# function you're using to call the database stored procedure is name of type int?
. Given that, following might solve your issue :
public void storedProcedureName(Nullable<int> id, string name)
{
var idParameter = id.HasValue ?
new SqlParameter("Id", id) :
new SqlParameter { ParameterName = "Id", SqlDbType = SqlDbType.Int, Value = DBNull.Value };
// to be continued...
You are debugging two or more times. so the application may run more at a time. Then only this issue will occur. You should close all debugging applications using task-manager, Then debug again.
When you run composer update
, composer
generates a file called composer.lock
which lists all your packages and the currently installed versions. This allows you to later run composer install
, which will install the packages listed in that file, recreating the environment that you were last using.
It appears from your log that some of the versions of packages that are listed in your composer.lock
file are no longer available. Thus, when you run composer install
, it complains and fails. This is usually no big deal - just run composer update
and it will attempt to build a set of packages that work together and write a new composer.lock
file.
However, you're running into a different problem. It appears that, in your composer.json
file, the original developer has added some pre- or post- update actions that are failing, specifically a php artisan migrate
command. This can be avoided by running the following: composer update --no-scripts
This will run the composer update but will skip over the scripts added to the file. You should be able to successfully run the update this way.
However, this does not solve the problem long-term. There are two problems:
A migration is for database changes, not random stuff like compiling assets. Go through the migrations and remove that code from there.
Assets should not be compiled each time you run composer update
. Remove that step from the composer.json
file.
From what I've read, best practice seems to be compiling assets on an as-needed basis during development (ie. when you're making changes to your LESS files - ideally using a tool like gulp.js) and before deployment.
How about:

{
if (values == null) throw new ArgumentNullException("values");
var comparer = Comparer<T>.Default;
switch(values.Length) {
case 0: throw new ArgumentException();
case 1: return values[0];
case 2: return comparer.Compare(values[0],values[1]) < 0
? values[0] : values[1];
default:
T best = values[0];
for (int i = 1; i < values.Length; i++)
{
if (comparer.Compare(values[i], best) < 0)
{
best = values[i];
}
}
return best;
}
}
// overload for the common "2" case...
public static T Min<T>(T x, T y)
{
return Comparer<T>.Default.Compare(x, y) < 0 ? x : y;
}
Works with any type that supports IComparable<T>
or IComparable
.
Actually, with LINQ, another alternative is:
var min = new[] {x,y,z}.Min();
Try doing this :
awk '{print substr($0, 1, length($0)-1)}' file.txt
This is more generic than just removing the final comma but any last character
If you'd want to only remove the last comma with awk :
awk '{gsub(/,$/,""); print}' file.txt
More information will be useful.
When I was faced with the same error message all I had to do was to correctly configure the credentials page of the DataSource(I am using Report Builder 3). if you chose the default, the report would work fine in Report Builder but would fail on the Report Server.

You can make it do nothing by setting a type of button

You are mixing the 2 different CASE
syntaxes inappropriately.
Use this style (Searched)
CASE
WHEN u.nnmu ='0' THEN mu.naziv_mesta
WHEN u.nnmu ='1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
Or this style (Simple)
CASE u.nnmu
WHEN '0' THEN mu.naziv_mesta
WHEN '1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
Not This (Simple but with boolean search predicates)
CASE u.nnmu
WHEN u.nnmu ='0' THEN mu.naziv_mesta
WHEN u.nnmu ='1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
In MySQL this will end up testing whether u.nnmu
is equal to the value of the boolean expression u.nnmu ='0'
itself. Regardless of whether u.nnmu
is 1
or 0
the result of the case expression itself will be 1
For example if nmu = '0'
then (nnmu ='0'
) evaluates as true
(1) and (nnmu ='1'
) evaluates as false
(0). Substituting these into the case expression gives
SELECT CASE '0'
WHEN 1 THEN '0'
WHEN 0 THEN '1'
ELSE 'GRESKA'
END as mesto_utovara
if nmu = '1'
then (nnmu ='0'
) evaluates as false
(0) and (nnmu ='1'
) evaluates as true
(1). Substituting these into the case expression gives
SELECT CASE '1'
WHEN 0 THEN '0'
WHEN 1 THEN '1'
ELSE 'GRESKA'
END as mesto_utovara
If you have code in one subdirectory dependent on code in another subdirectory, you are probably better off with a single makefile at top-level.
See Recursive Make Considered Harmful for the full rationale, but basically you want make to have the full information it needs to decide whether or not a file needs to be rebuilt, and it won't have that if you only tell it about a third of your project.
The link above seems to be not reachable. The same document is reachable here:
The nohup
command only writes to nohup.out
if the output would otherwise go to the terminal. If you have redirected the output of the command somewhere else - including /dev/null
- that's where it goes instead.
nohup command >/dev/null 2>&1 # doesn't create nohup.out
If you're using nohup
, that probably means you want to run the command in the background by putting another &
on the end of the whole thing:
nohup command >/dev/null 2>&1 & # runs in background, still doesn't create nohup.out
On Linux, running a job with nohup
automatically closes its input as well. On other systems, notably BSD and macOS, that is not the case, so when running in the background, you might want to close input manually. While closing input has no effect on the creation or not of nohup.out
, it avoids another problem: if a background process tries to read anything from standard input, it will pause, waiting for you to bring it back to the foreground and type something. So the extra-safe version looks like this:
nohup command </dev/null >/dev/null 2>&1 & # completely detached from terminal
Note, however, that this does not prevent the command from accessing the terminal directly, nor does it remove it from your shell's process group. If you want to do the latter, and you are running bash, ksh, or zsh, you can do so by running disown
with no argument as the next command. That will mean the background process is no longer associated with a shell "job" and will not have any signals forwarded to it from the shell. (Note the distinction: a disown
ed process gets no signals forwarded to it automatically by its parent shell - but without nohup
, it will still receive a HUP
signal sent via other means, such as a manual kill
command. A nohup
'ed process ignores any and all HUP
signals, no matter how they are sent.)
Explanation:
In Unixy systems, every source of input or target of output has a number associated with it called a "file descriptor", or "fd" for short. Every running program ("process") has its own set of these, and when a new process starts up it has three of them already open: "standard input", which is fd 0, is open for the process to read from, while "standard output" (fd 1) and "standard error" (fd 2) are open for it to write to. If you just run a command in a terminal window, then by default, anything you type goes to its standard input, while both its standard output and standard error get sent to that window.
But you can ask the shell to change where any or all of those file descriptors point before launching the command; that's what the redirection (<
, <<
, >
, >>
) and pipe (|
) operators do.
The pipe is the simplest of these... command1 | command2
arranges for the standard output of command1
to feed directly into the standard input of command2
. This is a very handy arrangement that has led to a particular design pattern in UNIX tools (and explains the existence of standard error, which allows a program to send messages to the user even though its output is going into the next program in the pipeline). But you can only pipe standard output to standard input; you can't send any other file descriptors to a pipe without some juggling.
The redirection operators are friendlier in that they let you specify which file descriptor to redirect. So 0<infile
reads standard input from the file named infile
, while 2>>logfile
appends standard error to the end of the file named logfile
. If you don't specify a number, then input redirection defaults to fd 0 (<
is the same as 0<
), while output redirection defaults to fd 1 (>
is the same as 1>
).
Also, you can combine file descriptors together: 2>&1
means "send standard error wherever standard output is going". That means that you get a single stream of output that includes both standard out and standard error intermixed with no way to separate them anymore, but it also means that you can include standard error in a pipe.
So the sequence >/dev/null 2>&1
means "send standard output to /dev/null
" (which is a special device that just throws away whatever you write to it) "and then send standard error to wherever standard output is going" (which we just made sure was /dev/null
). Basically, "throw away whatever this command writes to either file descriptor".
When nohup
detects that neither its standard error nor output is attached to a terminal, it doesn't bother to create nohup.out
, but assumes that the output is already redirected where the user wants it to go.
The /dev/null
device works for input, too; if you run a command with </dev/null
, then any attempt by that command to read from standard input will instantly encounter end-of-file. Note that the merge syntax won't have the same effect here; it only works to point a file descriptor to another one that's open in the same direction (input or output). The shell will let you do >/dev/null <&1
, but that winds up creating a process with an input file descriptor open on an output stream, so instead of just hitting end-of-file, any read attempt will trigger a fatal "invalid file descriptor" error.
The file /tmp/mysql.sock
is probably a Named-Pipe, since it's in a temporary folder. A named pipe is a Special-File that never gets permanently stored.
If we make two programs, and we want one program to send a message to another program, we could create a text file. We have one program write something in the text file and the other program read what our other program wrote. That's what a pipe is, except it doesn't write the file to our computer hard disk, IE doesn't permanently store the file (like we do when we create a file and save it.)
A Socket is the exact same as a Pipe. The difference is that Sockets are usually used over a network -- between computers. A Socket sends information to another computer, or receives information from another computer. Both Pipes and Sockets use a temporary file to share so that they can 'communicate'.
It's difficult to discern which one MySql is using in this case. Doesn't matter though.
The command mysql.server start
should get the 'server' (program) running its infinite loop that will create that special-file and wait for changes (listen
for writes).
After that, a common issue might be that the MySql program doesn't have permission to create a file on your machine, so you might have to give it root privileges
sudo mysql.server start
I am wondering why you cannot put this in a batch file. Example:
cd D:\VBS\
WSCript Converter.vbs
Put the above code in a text file and save the text file with .bat extension. Now you have to simply run this .bat file.
You can create a protocol, conforming to the Swift LocalizedError
protocol, with these values:
protocol OurErrorProtocol: LocalizedError {
var title: String? { get }
var code: Int { get }
}
This then enables us to create concrete errors like so:
struct CustomError: OurErrorProtocol {
var title: String?
var code: Int
var errorDescription: String? { return _description }
var failureReason: String? { return _description }
private var _description: String
init(title: String?, description: String, code: Int) {
self.title = title ?? "Error"
self._description = description
self.code = code
}
}

Solutions proposed here either didn't work for me or where to large, so I was looking for something else and found the solution proposed by @dighan on bountysource.com/issues/
So here is the code that solved my problem:
var media = document.getElementById("YourVideo");
const playPromise = media.play();
if (playPromise !== null){
playPromise.catch(() => { media.play(); })
}
It still throws an error into console, but at least the video is playing :)
I'm agree with Vicente Plata you should try using jQuery IMHO is the best javascript library. You can create a class in your CSS file and just do the following with jquery:
$('#fName').addClass('name_of_the_class');
and that's all, and of course you won't be worried about incompatibility of the browsers, that's jquery's team problem :D LOL
You probably don't want to pass the car
object as a parameter, try just passing car.id
. What do you get when you inspect(params)
after clicking "Add to cart"?
In swift 4, I have solved it without needing to restart or use libraries.
After trying many options, I found this function, where you pass the stringToLocalize (of Localizable.String, the strings file) that you want to translate, and the language in which you want to translate it, and what it returns is the value for that String that you have in Strings file:
func localizeString (stringToLocalize: String, language: String) -> String
{
let path = Bundle.main.path (forResource: language, ofType: "lproj")
let languageBundle = Bundle (path: path!)
return languageBundle! .localizedString (forKey: stringToLocalize, value: "", table: nil)
}
Taking into account this function, I created this function in a Swift file:
struct CustomLanguage {
func createBundlePath () -> Bundle {
let selectedLanguage = //recover the language chosen by the user (in my case, from UserDefaults)
let path = Bundle.main.path(forResource: selectedLanguage, ofType: "lproj")
return Bundle(path: path!)!
}
}
To access from the whole app, and in each string of the rest of ViewControllers, instead of putting:
NSLocalizedString ("StringToLocalize", comment: “")
I have replaced it with
let customLang = CustomLanguage() //declare at top
let bundleLanguage = customLang.createBundle()
NSLocalizedString("StringToLocalize", tableName: nil, bundle: bundleLanguage, value: "", comment: “”) //use in each String
I do not know if it's the best way, but I found it very simple, and it works for me, I hope it helps you!
You can't select a sheet in a non-active workbook.
You must first activate the workbook, then you can select the sheet.
workbooks("A").activate
workbooks("A").worksheets("B").select
When you use Activate it automatically activates the workbook.
Note you can select >1 sheet in a workbook:
activeworkbook.sheets(array("sheet1","sheet3")).select
but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

If your your list is dynamically generated with unknown number and your target is to always have last div in a new line set last div class to "col-xl-12" and remove other classes so it will always take a full row.
This is a copy of your code corrected so that last div always occupy a full row (I although removed unnecessary classes).
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet">_x000D_
<div class="grid">_x000D_
<div class="row">_x000D_

Here's another CSS only solution that works with any HTML layout.
It works with any element you need to switch. Whatever your toggle layout is you just put it inside a couple of elements with the if-collapsed
and if-not-collapsed
classes inside the toggle element.
The only catch is that you have to make sure you put the desired initial state of the toggle. If it's initially closed, then put a collapsed
class on the toggle.
It also requires the :not
selector, so it doesn't work on IE8.
HTML example:
<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
<!--You can put any valid html inside these!-->
<span class="if-collapsed">Open</span>
<span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
<div class="well">
...
</div>
</div>
Less version:
[data-toggle="collapse"] {
&.collapsed .if-not-collapsed {
display: none;
}
&:not(.collapsed) .if-collapsed {
display: none;
}
}
CSS version:
[data-toggle="collapse"].collapsed .if-not-collapsed {
display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
display: none;
}

@Scheduled(cron = "0 1 1,13 * * ?", zone = "CST")
This will execute at 1.01 and 13.01. It can be used when you need to run the job without a pattern multiple times a day.
And the zone attribute is very useful, when you do deployments in remote servers. This was introduced with spring 4.

I have noticed that @Eyo Okon Eyo solution works as long as MySQL server is not restarted, then defaults settings are restored. Here is a permanent solution that worked for me:
To remove particular SQL mode (in this case ONLY_FULL_GROUP_BY), find the current SQL mode:
SELECT @@GLOBAL.sql_mode;
copy the result and remove from it what you don't need (ONLY_FULL_GROUP_BY)
e.g.:
ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
to
STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
create and open this file:
/etc/mysql/conf.d/disable_strict_mode.cnf
and write and past into it your new SQL mode:
[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
restart MySQL:
sudo service mysql restart
Or you can use ANY_VALUE()
to suppress ONLY_FULL_GROUP_BY value rejection, you can read more about it here

Enhancements the
ALTER TABLE
command:
- Add support for renaming columns within a table using
ALTER TABLE
tableRENAME COLUMN oldname TO newname
.- Fix table rename feature so that it also updates references to the renamed table in triggers and views.
You can find the new syntax documented under ALTER TABLE
The
RENAME COLUMN TO
syntax changes the column-name of table table-name into new-column-name. The column name is changed both within the table definition itself and also within all indexes, triggers, and views that reference the column. If the column name change would result in a semantic ambiguity in a trigger or view, then theRENAME COLUMN
fails with an error and no changes are applied.
Image source: https://www.sqlite.org/images/syntax/alter-table-stmt.gif
Example:
CREATE TABLE tab AS SELECT 1 AS c;
SELECT * FROM tab;
ALTER TABLE tab RENAME COLUMN c to c_new;
SELECT * FROM tab;
As of writing, Android's API 27 is using SQLite package version 3.19.
Based on the current version that Android is using and that this update is coming in version 3.25.0 of SQLite, I would say you have bit of a wait (approximately API 33) before support for this is added to Android.
And, even then, if you need to support any versions older than the API 33, you will not be able to use this.
Well the problem simply-put is that the SUM(TIME) for a specific SSN on your query is a single value, so it's objecting to MAX as it makes no sense (The maximum of a single value is meaningless).
Not sure what SQL database server you're using but I suspect you want a query more like this (Written with a MSSQL background - may need some translating to the sql server you're using):
SELECT TOP 1 SSN, SUM(TIME)
FROM downloads
GROUP BY SSN
ORDER BY 2 DESC
This will give you the SSN with the highest total time and the total time for it.
Edit - If you have multiple with an equal time and want them all you would use:
SELECT
SSN, SUM(TIME)
FROM downloads
GROUP BY SSN
HAVING SUM(TIME)=(SELECT MAX(SUM(TIME)) FROM downloads GROUP BY SSN))

Example 2 regex: a[0-7]c
a0c // match
a3c // match
a7c // match

Use the hat in square brackets [^]
to match any single character except for any of the characters that come after the hat ^
.
Example regex: a[^abc]c
aac // no match
abc // no match
acc // no match
a c // match
azc // match
ac // no match
azzc // no match
(Don't confuse the ^
here in [^]
with its other usage as the start of line character: ^

Use the optional character ?
after any character to specify zero or one occurrence of that character. Thus, you would use .?
to match any single character optionally.
Example regex: a.?c
abc // match
a c // match
azc // match
ac // match
abbc // no match
Here is my method made with pure PHP and CSS :
/** PHP code */
<?php
$string = "the string with linebreaks";
$string = strtr($string,array("."=>".\r\r",":"=>" : \r","-"=>"\r - "));
?>
And the CSS :
.your_textarea_class {
style='white-space:pre-wrap';
}
You can do the same with regex (I'm learning how to build regex with pregreplace using an associative array, seems to be better for adding the \n\r which makes the breaks display).
To my understanding synchronized basically means that the compiler write a monitor.enter and monitor.exit around your method. As such it may be thread safe depending on how it is used (what I mean is you can write an object with synchronized methods that isn't threadsafe depending on what your class does).

$decoded = json_decode($encoded);
echo $decoded->{'tag'};

There are two approaches that I know of. The first is to tell the browser not to cache the page. Setting the Response to no cache takes care of that, however as you suspect the browser will often ignore this directive. The other approach is to set the date time of your response to a point in the future. I believe all browsers will correct this to the current time when they add the page to the cache, but it will show the page as newer when the comparison is made. I believe there may be some cases where a comparison is not made. I am not sure of the details and they change with each new browser release. Final note I have had better luck with pages that "refresh" themselves (another response directive). The refresh seems less likely to come from the cache.
Hope that helps.
Try just setting the link color:
$("ul#mainFilter a").css('color','#000');
Edit: or better yet, use the CSS, as Christopher suggested
Here is the answer in Razor syntax
<table border="1" cellpadding="5">
<thead>
<tr>
@foreach (System.Data.DataColumn col in Model.Columns)
{
<th>@col.Caption</th>
}
</tr>
</thead>
<tbody>
@foreach(System.Data.DataRow row in Model.Rows)
{
<tr>
@foreach (var cell in row.ItemArray)
{
<td>@cell.ToString()</td>
}
</tr>
}
</tbody>
</table>
If you prefer simplicity and more control on SQL queries then I would suggest going with Spring Data/ Spring JDBC.
Its good amount of learning curve in JPA and sometimes difficult to debug issues. On the other hand, while you have full control over SQL, it becomes much easier to optimize query and improve performance. You can easily share your SQL with DBA or someone who has a better understanding of Database.
Though this is an old post and have many answers, but here I have my version of code to upload the file to sharepoint 2013 using CSOM(c#)
I hope if you are working with downloading and uploading files then you know how to create Clientcontext
object and Web
object
/* Assuming you have created ClientContext object and Web object*/
string listTitle = "List title where you want your file to upload";
string filePath = "your file physical path";
List oList = web.Lists.GetByTitle(listTitle);
clientContext.Load(oList.RootFolder);//to load the folder where you will upload the file
FileCreationInformation fileInfo = new FileCreationInformation();
fileInfo.Overwrite = true;
fileInfo.Content = System.IO.File.ReadAllBytes(filePath);
fileInfo.Url = fileName;
File fileToUpload = fileCollection.Add(fileInfo);
clientContext.ExecuteQuery();
fileToUpload.CheckIn("your checkin comment", CheckinType.MajorCheckIn);
if (oList.EnableMinorVersions)
{
fileToUpload.Publish("your publish comment");
clientContext.ExecuteQuery();
}
if (oList.EnableModeration)
{
fileToUpload.Approve("your approve comment");
}
clientContext.ExecuteQuery();
And here is the code for download
List oList = web.Lists.GetByTitle("ListNameWhereFileExist");
clientContext.Load(oList);
clientContext.Load(oList.RootFolder);
clientContext.Load(oList.RootFolder.Files);
clientContext.ExecuteQuery();
FileCollection fileCollection = oList.RootFolder.Files;
File SP_file = fileCollection.GetByUrl("fileNameToDownloadWithExtension");
clientContext.Load(SP_file);
clientContext.ExecuteQuery();
var Local_stream = System.IO.File.Open("c:/testing/" + SP_file.Name, System.IO.FileMode.CreateNew);
var fileInformation = File.OpenBinaryDirect(clientContext, SP_file.ServerRelativeUrl);
var Sp_Stream = fileInformation.Stream;
Sp_Stream.CopyTo(Local_stream);
Still there are different ways I believe that can be used to upload and download.
I'm running Oracle VM Virtualbox on Ubuntu 16.04 LTS.
The solution that worked was to reinstall virtualbox as mentioned here:
sudo apt remove virtualbox virtualbox-5.0 virtualbox-4.*
sudo apt-get install virtualbox
I couldn't find my VirtualBox installation folder, as such could not issue the command:
$sudo /Library/StartupItems/VirtualBox/VirtualBox restart
how about using the CSS :first-child pseudo-class:
.MyClass td:first-child { border: solid 1px red; }
gcc 7.4.0 can not compile codes as below:
#include <stdio.h>
const char * const str1 = "str1";
const char * str2 = str1;
int main() {
printf("%s - %s\n", str1, str2);
return 0;
}
constchar.c:3:21: error: initializer element is not constant const char * str2 = str1;
In fact, a "const char *" string is not a compile-time constant, so it can't be an initializer. But a "const char * const" string is a compile-time constant, it should be able to be an initializer. I think this is a small drawback of CLang.
A function name is of course a compile-time constant.So this code works:
void func(void)
{
printf("func\n");
}
typedef void (*func_type)(void);
func_type f = func;
int main() {
f();
return 0;
}
The similar to Java's method is:
Regex.Split(string, pattern);
where
string
- the text you need to splitpattern
- string type pattern, what is splitting the textThat error message means that there was not response OR the server could not be connected.
The following settings worked on my end:
'stream' => [
'ssl' => [
'allow_self_signed' => true,
'verify_peer' => false,
'verify_peer_name' => false,
],
]
Note that my SMTP settings are:
MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
MAIL_USERNAME=[full gmail address]
MAIL_PASSWORD=[App Password obtained after two step verification]
MAIL_ENCRYPTION=ssl
This should do what you want:
print tempfile.gettempdir()
For me on my Windows box, I get:
c:\temp
and on my Linux box I get:
/tmp
The LEFT OUTER JOIN will return all records from the LEFT table joined with the RIGHT table where possible.
If there are matches though, it will still return all rows that match, therefore, one row in LEFT that matches two rows in RIGHT will return as two ROWS, just like an INNER JOIN.
EDIT: In response to your edit, I've just had a further look at your query and it looks like you are only returning data from the LEFT table. Therefore, if you only want data from the LEFT table, and you only want one row returned for each row in the LEFT table, then you have no need to perform a JOIN at all and can just do a SELECT directly from the LEFT table.
I would have a look at Spring JDBC. I use it whenever I need to execute SQLs programatically. Example:
int countOfActorsNamedJoe
= jdbcTemplate.queryForInt("select count(0) from t_actors where first_name = ?", new Object[]{"Joe"});
It's really great for any kind of sql execution, especially querying; it will help you map resultsets to objects, without adding the complexity of a complete ORM.
With jquery you can use event object type
jQuery(".element").on("click contextmenu", function(e){
if(e.type == "contextmenu") {
alert("Right click");
}
});
$num += (6-$num%6)%6;
no need for a while loop! Modulo (%) returns the remainder of a division. IE 20%6 = 2. 6-2 = 4. 20+4 = 24. 24 is divisible by 6.
