For 8085: Stack pointer is a special purpose 16-bit register in the Microprocessor, which holds the address of the top of the stack.
The stack pointer register in a computer is made available for general purpose use by programs executing at lower privilege levels than interrupt handlers. A set of instructions in such programs, excluding stack operations, stores data other than the stack pointer, such as operands, and the like, in the stack pointer register. When switching execution to an interrupt handler on an interrupt, return address data for the currently executing program is pushed onto a stack at the interrupt handler's privilege level. Thus, storing other data in the stack pointer register does not result in stack corruption. Also, these instructions can store data in a scratch portion of a stack segment beyond the current stack pointer.

That character is the BOM or "Byte Order Mark". It is usually received as the first few bytes of a file, telling you how to interpret the encoding of the rest of the data. You can simply remove the character to continue. Although, since the error says you were trying to convert to 'ascii', you should probably pick another encoding for whatever you were trying to do.
There is no str
accessor for datetimes and you can't do dates.astype(str)
either, you can call apply
and use datetime.strftime
:
In [73]:
dates = pd.to_datetime(pd.Series(['20010101', '20010331']), format = '%Y%m%d')
dates.apply(lambda x: x.strftime('%Y-%m-%d'))
Out[73]:
0 2001-01-01
1 2001-03-31
dtype: object
You can change the format of your date strings using whatever you like: strftime() and strptime() Behavior.
Update
As of version 0.17.0
you can do this using dt.strftime
dates.dt.strftime('%Y-%m-%d')
will now work
I use this query in order to retrieve the server name of my Oracle database.
SELECT program FROM v$session WHERE program LIKE '%(PMON)%';
This question has many, many duplicates, including questions not mentioning the Chai assertion library. Here are the basics collected together:
The assertion must call the function, instead of it evaluating immediately.
assert.throws(x.y.z);
// FAIL. x.y.z throws an exception, which immediately exits the
// enclosing block, so assert.throw() not called.
assert.throws(()=>x.y.z);
// assert.throw() is called with a function, which only throws
// when assert.throw executes the function.
assert.throws(function () { x.y.z });
// if you cannot use ES6 at work
function badReference() { x.y.z }; assert.throws(badReference);
// for the verbose
assert.throws(()=>model.get(z));
// the specific example given.
homegrownAssertThrows(model.get, z);
// a style common in Python, but not in JavaScript
You can check for specific errors using any assertion library:
assert.throws(() => x.y.z);
assert.throws(() => x.y.z, ReferenceError);
assert.throws(() => x.y.z, ReferenceError, /is not defined/);
assert.throws(() => x.y.z, /is not defined/);
assert.doesNotThrow(() => 42);
assert.throws(() => x.y.z, Error);
assert.throws(() => model.get.z, /Property does not exist in model schema./)
should.throws(() => x.y.z);
should.throws(() => x.y.z, ReferenceError);
should.throws(() => x.y.z, ReferenceError, /is not defined/);
should.throws(() => x.y.z, /is not defined/);
should.doesNotThrow(() => 42);
should.throws(() => x.y.z, Error);
should.throws(() => model.get.z, /Property does not exist in model schema./)
expect(() => x.y.z).to.throw();
expect(() => x.y.z).to.throw(ReferenceError);
expect(() => x.y.z).to.throw(ReferenceError, /is not defined/);
expect(() => x.y.z).to.throw(/is not defined/);
expect(() => 42).not.to.throw();
expect(() => x.y.z).to.throw(Error);
expect(() => model.get.z).to.throw(/Property does not exist in model schema./);
You must handle exceptions that 'escape' the test
it('should handle escaped errors', function () {
try {
expect(() => x.y.z).not.to.throw(RangeError);
} catch (err) {
expect(err).to.be.a(ReferenceError);
}
});
This can look confusing at first. Like riding a bike, it just 'clicks' forever once it clicks.
Use the following:
echo $form->field($model, 'hidden1')->hiddenInput(['value'=> $value])->label(false);
I usually do as you describe:
Add a separate column with a random value (=RAND()
) and then perform a sort on that column.
Might be more complex and prettyer ways (using macros etc), but this is fast enough and simple enough for me.
Verify current version of python by:
$ python --version
then check python is symbolic link to which file.
$ ll /usr/bin/python
Output Ex:
lrwxrwxrwx 1 root root 9 Jun 16 2014 /usr/bin/python -> python2.7*
Check other available versions of python:
$ ls /usr/bin/python*
Output Ex:
/usr/bin/python /usr/bin/python2.7-config /usr/bin/python3.4 /usr/bin/python3.4m-config /usr/bin/python3.6m /usr/bin/python3m
/usr/bin/python2 /usr/bin/python2-config /usr/bin/python3.4-config /usr/bin/python3.6 /usr/bin/python3.6m-config /usr/bin/python3m-config
/usr/bin/python2.7 /usr/bin/python3 /usr/bin/python3.4m /usr/bin/python3.6-config /usr/bin/python3-config /usr/bin/python-config
If want to change current version of python to 3.6 version edit file ~/.bashrc:
vim ~/.bashrc
add below line in the end of file and save:
alias python=/usr/local/bin/python3.6
To install pip for python 3.6
$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip
On Success, check current version of pip:
$ pip3 -V
Output Ex:
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)
You need to open TCP port 8787 in the ec2 Security Group. Also need to open the same port on the EC2 instance's firewall.
"Sometimes" this can mean that the server had an internal error, and wanted to respond with an error message (ex: 500 with JSON payload) but since the request headers didn't say it accepted JSON, it returns a 406 instead. Go figure. (in this case: spring boot webapp).
In which case, your operation did fail. But the failure message was obscured by another.
You have to set the proper font path. e.g.
$fa-font-path:"../node_modules/font-awesome/fonts";
@import "../node_modules/font-awesome/scss/font-awesome";
.icon-user {
@extend .fa;
@extend .fa-user;
}

C:\python367\Scripts>pip install Flask
Collecting Flask Could not find a version that satisfies the requirement Flask (from versions: ) No matching distribution found for Flask
After that, I find the pip configuration file had been modified. So, I set the pip.ini
as the original default configuration, re-run the pip command and it works for me!
In summary of the solution of mine:
Check the pip.ini (usually under the path C:\ProgramData\pip
) had been modified;
If yes in step1, try to reset it to a default configuration.
I got it fixed by running "C:\Program Files\Android\android-sdk\AVD Manager.exe" and repairing my broken device.
I had the same error and my problem was the file permissions were incorrect.
chmod 755 index.php
worked for me.

Open web.config file and find the System.Web.Mvc assembly definition:
assembly="System.Web.Mvc, Version=3.0.0.0 ..."
It's an MVC3 as you see. Via web you can use MvcDiagnostics which is similar to phpinfo()
functionality in PHP.
As you can see in the below source code, BeanUtils.copyProperties internally uses reflection and there's additional internal cache lookup steps as well which is going to add cost wrt performance
private static void copyProperties(Object source, Object target, @Nullable Class<?> editable,
@Nullable String... ignoreProperties) throws BeansException {
Assert.notNull(source, "Source must not be null");
Assert.notNull(target, "Target must not be null");
Class<?> actualEditable = target.getClass();
if (editable != null) {
if (!editable.isInstance(target)) {
throw new IllegalArgumentException("Target class [" + target.getClass().getName() +
"] not assignable to Editable class [" + editable.getName() + "]");
}
actualEditable = editable;
}
**PropertyDescriptor[] targetPds = getPropertyDescriptors(actualEditable);**
List<String> ignoreList = (ignoreProperties != null ? Arrays.asList(ignoreProperties) : null);
for (PropertyDescriptor targetPd : targetPds) {
Method writeMethod = targetPd.getWriteMethod();
if (writeMethod != null && (ignoreList == null || !ignoreList.contains(targetPd.getName()))) {
PropertyDescriptor sourcePd = getPropertyDescriptor(source.getClass(), targetPd.getName());
if (sourcePd != null) {
Method readMethod = sourcePd.getReadMethod();
if (readMethod != null &&
ClassUtils.isAssignable(writeMethod.getParameterTypes()[0], readMethod.getReturnType())) {
try {
if (!Modifier.isPublic(readMethod.getDeclaringClass().getModifiers())) {
readMethod.setAccessible(true);
}
Object value = readMethod.invoke(source);
if (!Modifier.isPublic(writeMethod.getDeclaringClass().getModifiers())) {
writeMethod.setAccessible(true);
}
writeMethod.invoke(target, value);
}
catch (Throwable ex) {
throw new FatalBeanException(
"Could not copy property '" + targetPd.getName() + "' from source to target", ex);
}
}
}
}
}
}
So it's better to use plain setters given the cost reflection
I'm assuming that you are using React-Router V4, as you used the same in the original Sandbox Link.
You are rendering the Main
component in the call to ReactDOM.render
that renders a Link
and Main component is outside of Router
, that's why it is throwing the error:
You should not use <Link> outside a <Router>
Changes:
Use any one of these Routers, BrowserRouter/HashRouter etc..., because you are using React-Router V4.
Router can have only one child, so wrap all the routes in a div
or Switch.
React-Router V4, doesn't have the concept of nested routes, if you wants to use nested routes then define those routes directly inside that component.
Check this working example with each of these changes.
const App = () => (
<BrowserRouter>
<div className="sans-serif">
<Route path="/" component={Main} />
<Route path="/view/:postId" component={Single} />
</div>
</BrowserRouter>
);
render(<App />, document.getElementById('root'));
Main
component from routeimport React from 'react';
import { Link } from 'react-router-dom';
export default () => (
<div>
<h1>
<Link to="/">Redux example</Link>
</h1>
</div>
)
Etc.
Also check this answer: Nested routes with react router v4
When using an iframe, you will first have to switch to the iframe, before selecting the elements of that iframe
You can do it using:
driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();
In case if your frameId is dynamic, and you only have one iframe, you can use something like:
driver.switchTo().frame(driver.findElement(By.tagName("iframe")));
Open Notepad.
Type the following lines into it (obviously replace the folders with your ones)
@echo off
rem you could also remove the line above, because it might help you to see what happens
rem /i option is needed to avoid the batch file asking you whether destination folder is a file or a folder
rem /e option is needed to copy also all folders and subfolders
xcopy "c:\New Folder" "c:\Copy of New Folder" /i /e
Save the file as backup.bat (not .txt)
Double click on the file to run it. It will backup the folder and all its contents files/subfolders.
Now if you want the batch file to be run everytime you login in Windows, you should place it in Windows Startup menu. You find it under: Start > All Program > Startup To place the batch file in there either drag it into the Startup menu or RIGH click on the Windows START button and select Explore, go in Programs > Startup, and copy the batch file into there.
To run the batch file everytime the folder is updated you need an application, it can not be done with just a batch file.
In Python, a list
is a dynamic array. You can create one like this:
lst = [] # Declares an empty list named lst
Or you can fill it with items:
lst = [1,2,3]
You can add items using "append":
lst.append('a')
You can iterate over elements of the list using the for
loop:
for item in lst:
# Do something with item
Or, if you'd like to keep track of the current index:
for idx, item in enumerate(lst):
# idx is the current idx, while item is lst[idx]
To remove elements, you can use the del command or the remove function as in:
del lst[0] # Deletes the first item
lst.remove(x) # Removes the first occurence of x in the list
Note, though, that one cannot iterate over the list and modify it at the same time; to do that, you should instead iterate over a slice of the list (which is basically a copy of the list). As in:
for item in lst[:]: # Notice the [:] which makes a slice
# Now we can modify lst, since we are iterating over a copy of it
In the format property of any textbox field you can use format strings:
e.g. D/M/Y, D, etc.

The problem is the padding of the font on the textview. Just add to your textview:
android:includeFontPadding="false"

I found this suggestion useful in my case:
def product_params
params.require(:product).permit(:name).tap do |whitelisted|
whitelisted[:data] = params[:product][:data]
end
end
Check this link of Xavier's comment on github.
This approach whitelists the entire params[:measurement][:groundtruth] object.
Using the original questions attributes:
def product_params
params.require(:measurement).permit(:name, :groundtruth).tap do |whitelisted|
whitelisted[:groundtruth] = params[:measurement][:groundtruth]
end
end

This fixed it for me: Open maven projects tab on the right. Add the pom if not yet present, then click refresh on the top left of the tab.
In fact, this is a "how to" subject. So, here is the reference implementation:
public class BOX
{
double height, length, breadth;
public static bool operator == (BOX b1, BOX b2)
{
if ((object)b1 == null)
return (object)b2 == null;
return b1.Equals(b2);
}
public static bool operator != (BOX b1, BOX b2)
{
return !(b1 == b2);
}
public override bool Equals(object obj)
{
if (obj == null || GetType() != obj.GetType())
return false;
var b2 = (BOX)obj;
return (length == b2.length && breadth == b2.breadth && height == b2.height);
}
public override int GetHashCode()
{
return height.GetHashCode() ^ length.GetHashCode() ^ breadth.GetHashCode();
}
}
REF: https://msdn.microsoft.com/en-us/library/336aedhh(v=vs.100).aspx#Examples
UPDATE: the cast to (object)
in the operator ==
implementation is important, otherwise, it would re-execute the operator == overload, leading to a stackoverflow. Credits to @grek40.
This (object)
cast trick is from Microsoft String

You have mostly the right idea, it's just the sending of the form that is wrong. The form belongs in the body of the request.
req, err := http.NewRequest("POST", url, strings.NewReader(form.Encode()))
Unless there is some compelling reason to use a regex, I would just use String.startsWith:
bool matches = test.startsWith("http://")
|| test.startsWith("https://")
|| test.startsWith("ftp://");
I wouldn't be surprised if this is faster, too.
Sadly, you can't. From the grep
docs:
grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus (-) is given as file name) for lines containing a match to the given PATTERN.
Vue by default ships with the v-html directive to show it, you bind it onto the element itself rather than using the normal moustache binding for string variables.
So for your specific example you would need:
<div id="logapp">
<table>
<tbody>
<tr v-repeat="logs">
<td v-html="fail"></td>
<td v-html="type"></td>
<td v-html="description"></td>
<td v-html="stamp"></td>
<td v-html="id"></td>
</tr>
</tbody>
</table>
</div>
Here you go other approach with less looping:
calculateTotalMonthsDifference = function(firstDate, secondDate) {
var fm = firstDate.getMonth();
var fy = firstDate.getFullYear();
var sm = secondDate.getMonth();
var sy = secondDate.getFullYear();
var months = Math.abs(((fy - sy) * 12) + fm - sm);
var firstBefore = firstDate > secondDate;
firstDate.setFullYear(sy);
firstDate.setMonth(sm);
firstBefore ? firstDate < secondDate ? months-- : "" : secondDate < firstDate ? months-- : "";
return months;
}

To read only the first row of the csv file use next()
on the reader object.
with open('some.csv', newline='') as f:
reader = csv.reader(f)
row1 = next(reader) # gets the first line
# now do something here
# if first row is the header, then you can do one more next() to get the next row:
# row2 = next(f)
or :
with open('some.csv', newline='') as f:
reader = csv.reader(f)
for row in reader:
# do something here with `row`

I'm using Java 8, JDBC driver with MySQL connector v. 5.1.31.
I may get real SQL string using this method:
// 1. make connection somehow, it's conn variable
// 2. make prepered statement template
PreparedStatement stmt = conn.prepareStatement(
"INSERT INTO oc_manufacturer" +
" SET" +
" manufacturer_id = ?," +
" name = ?," +
" sort_order=0;"
);
// 3. fill template
stmt.setInt(1, 23);
stmt.setString(2, 'Google');
// 4. print sql string
System.out.println(((JDBC4PreparedStatement)stmt).asSql());
So it returns smth like this:
INSERT INTO oc_manufacturer SET manufacturer_id = 23, name = 'Google', sort_order=0;
This is a common problem . when we start the ftp connection only the external ip opens the port for pasv connection. but the ip behind the NAT doesn't open the connection so passive connection fails with PASV command
we need to specify that while opening the connection so open connection with
ftp -p {host}
WebClient is a higher-level abstraction built on top of HttpWebRequest to simplify the most common tasks. For instance, if you want to get the content out of an HttpWebResponse, you have to read from the response stream:
var http = (HttpWebRequest)WebRequest.Create("http://example.com");
var response = http.GetResponse();
var stream = response.GetResponseStream();
var sr = new StreamReader(stream);
var content = sr.ReadToEnd();
With WebClient, you just do DownloadString
:
var client = new WebClient();
var content = client.DownloadString("http://example.com");
Note: I left out the using
statements from both examples for brevity. You should definitely take care to dispose your web request objects properly.
In general, WebClient is good for quick and dirty simple requests and HttpWebRequest is good for when you need more control over the entire request.
I always use the x:Name variant. I have no idea if this affects any performance, I just find it easier for the following reason. If you have your own usercontrols that reside in another assembly just the "Name" property won't always suffice. This makes it easier to just stick too the x:Name property.

$server_output = curl_exec($ch);

You can add a callback function to your list of get_category(...) parameters.
Ex:
get_categories(number, callback){
this.http.post( url, body, {headers: headers, withCredentials:true})
.subscribe(
response => {
this.total = response.json();
callback();
}, error => {
}
);
}
And then you can just call get_category(...) like this:
this.get_category(1, name_of_function);
Since you have written a function named foo
and you know it is in myfile.js
why do you need to get this information dynamically?
That being said you can use arguments.callee.toString()
inside the function (this is a string representation of the entire function) and regex out the value of the function name.
Here is a function that will spit out its own name:
function foo() {
re = /^function\s+([^(]+)/
alert(re.exec(arguments.callee.toString())[1]);
}
Check this:
var minutesLabel = document.getElementById("minutes");_x000D_
var secondsLabel = document.getElementById("seconds");_x000D_
var totalSeconds = 0;_x000D_
setInterval(setTime, 1000);_x000D_
_x000D_
function setTime() {_x000D_
++totalSeconds;_x000D_
secondsLabel.innerHTML = pad(totalSeconds % 60);_x000D_
minutesLabel.innerHTML = pad(parseInt(totalSeconds / 60));_x000D_
}_x000D_
_x000D_
function pad(val) {_x000D_
var valString = val + "";_x000D_
if (valString.length < 2) {_x000D_
return "0" + valString;_x000D_
} else {_x000D_
return valString;_x000D_
}_x000D_
}
_x000D_
<label id="minutes">00</label>:<label id="seconds">00</label>

Addition to Alex' answer:
$(function() {
$('input[type="submit"]').prop('disabled', true);
$('#check').on('input', function(e) {
if(this.value.length === 6) {
$('input[type="submit"]').prop('disabled', false);
} else {
$('input[type="submit"]').prop('disabled', true);
}
});
});
<input type="text" maxlength="6" id="check" data-minlength="6" /><br />
<input type="submit" value="send" />
But: You should always remember to validate the user input on the server side again. The user could modify the local HTML or disable JavaScript.
In JavaScript it has no special significance (no more than a
or Q
anyway). It is just an uninformative variable name.
In jQuery the variable is assigned a copy of the jQuery
function. This function is heavily overloaded and means half a dozen different things depending on what arguments it is passed. In this particular example you are passing it a string that contains a selector, so the function means "Create a jQuery object containing the element with the id Text".
The problem is somewhere else in your code, because this works:
string line("test\ttest2\ttest3");
vector<string> strs;
boost::split(strs,line,boost::is_any_of("\t"));
cout << "* size of the vector: " << strs.size() << endl;
for (size_t i = 0; i < strs.size(); i++)
cout << strs[i] << endl;
and testing your approach, which uses a vector iterator also works:
string line("test\ttest2\ttest3");
vector<string> strs;
boost::split(strs,line,boost::is_any_of("\t"));
cout << "* size of the vector: " << strs.size() << endl;
for (vector<string>::iterator it = strs.begin(); it != strs.end(); ++it)
{
cout << *it << endl;
}
Again, your problem is somewhere else. Maybe what you think is a \t
character on the string, isn't. I would fill the code with debugs, starting by monitoring the insertions on the vector to make sure everything is being inserted the way its supposed to be.
Output:
* size of the vector: 3
test

I think this should work?
substr($mystring, 0, (($pos = (strpos($mystring, '/') !== false)) ? $pos : strlen($mystring)));
Get Drawable from vector resource irrespective of, whether its vector or not:
AppCompatResources.getDrawable(context, R.drawable.icon);
Note:
ContextCompat.getDrawable(context, R.drawable.icon);
will produce android.content.res.Resources$NotFoundException
for vector resource.
This worked for me
#Mount as ReadOnly
su -c "mount -o rw,remount /system"
# Change Permission for file
su -c "chmod 777 /system/build.prop"
#Edit the file to add the property
su -c "busybox vi /system/build.prop"
# Add now
service.adb.tcp.port=5678
# Reset old permissions
su -c "chmod 644 /system/build.prop"
# Mount as readonly again once done
su -c "mount -o ro,remount /system"
I just solved this kind of a problem. What I've learned is:
my.cnf
and set the bind-address = your.mysql.server.address
under [mysqld]
check if it's running
mysql -u root -h your.mysql.server.address –p
create a user (usr or anything) with % as domain and grant her access to the database in question.
mysql> CREATE USER 'usr'@'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON testDb.* TO 'monty'@'%' WITH GRANT OPTION;
open firewall for port 3306 (you can use iptables. make sure to open port for eithe reveryone, or if you're in tight securety, then only allow the client address)
you should be able to now connect mysql server form your client server php script.
An easy option is to configure matplotlib to automatically adjust the plot size. It works perfectly for me and I'm not sure why it's not activated by default.
Method 1
Set this in your matplotlibrc file
figure.autolayout : True
See here for more information on customizing the matplotlibrc file: http://matplotlib.org/users/customizing.html
Method 2
Update the rcParams during runtime like this
from matplotlib import rcParams
rcParams.update({'figure.autolayout': True})
The advantage of using this approach is that your code will produce the same graphs on differently-configured machines.
var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);
You may do the following:
git -m master master-old #rename current master
git checkout -b master #create a new branch master
git push -f origin master #force push to master
But force pushing is a bad idea if other people are sharing this repository. Force push will cause their revision history to conflict with the new one.
Swift Version tested:
//Somewhere in your UIViewController, like viewDidLoad(){ ... }
self.textField.addTarget(
self,
action: #selector(SearchViewController.textFieldDidChange(_:)),
forControlEvents: UIControlEvents.EditingChanged
)
Parameters explained:
self.textField //-> A UITextField defined somewhere in your UIViewController
self //-> UIViewController
.textFieldDidChange(_:) //-> Can be named anyway you like, as long as it is defined in your UIViewController
Then add the method you created above in your UIViewController
:
//Gets called everytime the text changes in the textfield.
func textFieldDidChange(textField: UITextField){
print("Text changed: " + textField.text!)
}
Location is a struct. If there aren't any convenience members, you'll need to reassign the entire Location:
this.balancePanel.Location = new Point(
this.optionsPanel.Location.X,
this.balancePanel.Location.Y);
Most structs are also immutable, but in the rare (and confusing) case that it is mutable, you can also copy-out, edit, copy-in;
var loc = this.balancePanel.Location;
loc.X = this.optionsPanel.Location.X;
this.balancePanel.Location = loc;
Although I don't recommend the above, since structs should ideally be immutable.
In Sailsjs there are two ways to configure all the stuff, first is to configure in config folder with each one has their separate files (like database connection regarding settings lies within connections.js ). And second is configure on environment base file structure, each environment files presents in config/env
folder and each file contains settings for particular env.
Sails first looks in config/env folder and then look forward to config/ *.js
Now lets setup ssl in config/local.js
.
var local = {
port: process.env.PORT || 1337,
environment: process.env.NODE_ENV || 'development'
};
if (process.env.NODE_ENV == 'production') {
local.ssl = {
secureProtocol: 'SSLv23_method',
secureOptions: require('constants').SSL_OP_NO_SSLv3,
ca: require('fs').readFileSync(__dirname + '/path/to/ca.crt','ascii'),
key: require('fs').readFileSync(__dirname + '/path/to/jsbot.key','ascii'),
cert: require('fs').readFileSync(__dirname + '/path/to/jsbot.crt','ascii')
};
local.port = 443; // This port should be different than your default port
}
module.exports = local;
Alternative you can add this in config/env/production.js too. (This snippet also show how to handle multiple CARoot certi)
Or in production.js
module.exports = {
port: 443,
ssl: {
secureProtocol: 'SSLv23_method',
secureOptions: require('constants').SSL_OP_NO_SSLv3,
ca: [
require('fs').readFileSync(__dirname + '/path/to/AddTrustExternalCARoot.crt', 'ascii'),
require('fs').readFileSync(__dirname + '/path/to/COMODORSAAddTrustCA.crt', 'ascii'),
require('fs').readFileSync(__dirname + '/path/to/COMODORSADomainValidationSecureServerCA.crt', 'ascii')
],
key: require('fs').readFileSync(__dirname + '/path/to/jsbot.key', 'ascii'),
cert: require('fs').readFileSync(__dirname + '/path/to/jsbot.crt', 'ascii')
}
};
Here ws is Web Socket and wss represent Secure Web Socket, as we set up ssl then now http and ws both requests become secure and transform to https and wss respectively.
There are many source from our app will receive request like any blog post, social media post but our server runs only on https so when any request come from http it gives “This site can’t be reached” error in client browser. And we loss our website traffic. So we must redirect http request to https, same rules allow for websocket otherwise socket will fails.
So we need to run same server on port 80 (http), and divert all request to port 443(https). Sails first compile config/bootstrap.js file before lifting server. Here we can start our express server on port 80.
In config/bootstrap.js (Create http server and redirect all request to https)
module.exports.bootstrap = function(cb) {
var express = require("express"),
app = express();
app.get('*', function(req, res) {
if (req.isSocket)
return res.redirect('wss://' + req.headers.host + req.url)
return res.redirect('https://' + req.headers.host + req.url)
}).listen(80);
cb();
};
Now you can visit http://www.yourdomain.com, it will redirect to https://www.yourdomain.com
All,
Here a little bit twist with mysql-community-server 5.7 I share some steps, how to reset mysql5.7 root password or set password. it will work centos7 and RHEL7 as well.
step1. 1st stop your databases
service mysqld stop
step2. 2nd modify /etc/my.cnf file add "skip-grant-tables"
vi /etc/my.cnf
[mysqld] skip-grant-tables
step3. 3rd start mysql
service mysqld start
step4. select mysql default database
mysql -u root
mysql>use mysql;
step4. set a new password
mysql> update user set authentication_string=PASSWORD("yourpassword") where User='root'
;
step5 restart mysql database
service mysqld restart
mysql -u root -p
enjoy :)

You'll also need to ensure you've implemented a suitable operator==()
for your object, if the default one isn't sufficient for a "deep" equality test.

From your ant buildfile, I assume that what you want is to create a single JAR archive that will contain not only your application classes, but also the contents of other JARs required by your application.
However your build-jar
file is just putting required JARs inside your own JAR; this will not work as explained here (see note).
Try to modify this:
<jar destfile="${jar.file}"
basedir="${build.dir}"
manifest="${manifest.file}">
<fileset dir="${classes.dir}" includes="**/*.class" />
<fileset dir="${lib.dir}" includes="**/*.jar" />
</jar>
to this:
<jar destfile="${jar.file}"
basedir="${build.dir}"
manifest="${manifest.file}">
<fileset dir="${classes.dir}" includes="**/*.class" />
<zipgroupfileset dir="${lib.dir}" includes="**/*.jar" />
</jar>
More flexible and powerful solutions are the JarJar or One-Jar projects. Have a look into those if the above does not satisfy your requirements.
I don't know what version of CI you were using back in 2013, but I am using CI3 and I just tested with two null
parameters passed to limit()
and there was no LIMIT
or OFFSET
in the rendered query (I checked by using get_compiled_select()
).
This means that -- assuming your have correctly posted your coding attempt -- you don't need to change anything (or at least the old issue is no longer a CI issue).
If this was my project, this is how I would write the method to return an indexed array of objects or an empty array if there are no qualifying rows in the result set.
function nationList($limit = null, $start = null) {
// assuming the language value is sanitized/validated/whitelisted
return $this->db
->select('nation.id, nation.name_' . $this->session->userdata('language') . ' AS name')
->from('nation')
->order_by("name")
->limit($limit, $start)
->get()
->result();
}
These refinements remove unnecessary syntax, conditions, and the redundant loop.
For reference, here is the CI core code:
/**
* LIMIT
*
* @param int $value LIMIT value
* @param int $offset OFFSET value
* @return CI_DB_query_builder
*/
public function limit($value, $offset = 0)
{
is_null($value) OR $this->qb_limit = (int) $value;
empty($offset) OR $this->qb_offset = (int) $offset;
return $this;
}
So the $this->qb_limit
and $this->qb_offset
class objects are not updated because null
evaluates as true
when fed to is_null()
or empty()
.
You can do this with JQueryUI:
$('a').mouseenter(function(){
$(this).animate({
color: '#ff0000'
}, 1000);
}).mouseout(function(){
$(this).animate({
color: '#000000'
}, 1000);
});
Here is my solution:
use form-data and edit as below:
Key Value
box[] a
box[n1] b
box[n2][] c
box[n2][] d
and you will get an array like this:
{"box":{"0":"a","n1":"b","n2":["c","d"]}}
This works for me:
File file = ...;
byte[] data = new byte[(int) file.length()];
try {
new FileInputStream(file).read(data);
} catch (Exception e) {
e.printStackTrace();
}
An easy way to check the CPU usage is to use the adb tool w/ top. I.e.:
adb shell top -m 10
The android developers example of loading bitmaps efficiently uses a custom asynctask (copied from jellybean) so you can use the executeOnExecutor in apis lower than < 11
http://developer.android.com/training/displaying-bitmaps/index.html
Download the code and go to util package.
sudo systemctl start docker
- to start the Docker service.
sudo docker-compose up
after that.
I have Fedora 26, and trying to solve the same issue I eventually entered Docker Compose on Fedora Developers' page and then Docker on Fedora Developers' page, which helped me.
Probably, docker service considered by community to start with the system and run in background all the time, but for me it was not so obvious, and that's the reason I can think of why there's no popular answer like this one.
On the Fedora Developers' page there's instruction how to enable Docker to start with the system:
sudo systemctl enable docker
There are multiple problems with yaluna's answer, also property names are case sensitive, Installed
is the correct spelling (INSTALLED
will not work).
The table above should've been this:
Also assuming a full repair & uninstall the actual values of properties could be:
The WiX Expression Syntax documentation says:
In these expressions, you can use property names (remember that they are case sensitive).
The properties are documented at the Windows Installer Guide (e.g. Installed)
EDIT: Small correction to the first table; evidently "Uninstall" can also happen with just REMOVE
being True
.
I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char
The main difference is ::
npm install is a npm cli-command which does the predefined thing i.e, as written by Churro, to install dependencies specified inside package.json
npm run command-name or npm run-script command-name ( ex. npm run build ) is also a cli-command predefined to run your custom scripts with the name specified in place of "command-name". So, in this case npm run build is a custom script command with the name "build" and will do anything specified inside it (for instance echo 'hello world' given in below example package.json).
Ponits to note::
One more thing, npm build
and npm run build
are two different things, npm run build
will do custom work written inside package.json
and npm build
is a pre-defined script (not available to use directly)
You cannot specify some thing inside custom build script (npm run build
) script and expect npm build
to do the same. Try following thing to verify in your package.json
:
{ "name": "demo", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "build":"echo 'hello build'" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": {}, "dependencies": {} }
and run npm run build
and npm build
one by one and you will see the difference. For more about commands kindly follow npm documentation.
Cheers!!
I got this error when I set cron job for my file. I changed the permissions of file to 777 but it still not worked for me. Finally I got the solution. May be it will be helpful for others.
Try with this command:
mysql -h 127.0.0.1 -P 3306 -u root -p
Remember that -h means host, -P means port and -p means password.

I recommend another option. jQuery UI has a new position feature that allows you to position elements relative to each other. For complete documentation and demo see: http://jqueryui.com/demos/position/#option-offset.
Here's one way to position your elements using the position feature:
var options = {
"my": "top left",
"at": "top left",
"of": ".layer1"
};
$(".layer2").position(options);
You may find that using the `group' aes will help you get the result you want. For example:
tu <- expand.grid(Land = gl(2, 1, labels = c("DE", "BB")),
Altersgr = gl(5, 1, labels = letters[1:5]),
Geschlecht = gl(2, 1, labels = c('m', 'w')),
Jahr = 2000:2009)
set.seed(42)
tu$Wert <- unclass(tu$Altersgr) * 200 + rnorm(200, 0, 10)
ggplot(tu, aes(x = Jahr, y = Wert, color = Altersgr, group = Altersgr)) +
geom_point() + geom_line() +
facet_grid(Geschlecht ~ Land)
Which produces the plot found here:
Rule of thumb: read the definition from right to left!
const int *foo;
Means "foo
points (*
) to an int
that cannot change (const
)".
To the programmer this means "I will not change the value of what foo
points to".
*foo = 123;
or foo[0] = 123;
would be invalid.foo = &bar;
is allowed.int *const foo;
Means "foo
cannot change (const
) and points (*
) to an int
".
To the programmer this means "I will not change the memory address that foo
refers to".
*foo = 123;
or foo[0] = 123;
is allowed.foo = &bar;
would be invalid.const int *const foo;
Means "foo
cannot change (const
) and points (*
) to an int
that cannot change (const
)".
To the programmer this means "I will not change the value of what foo
points to, nor will I change the address that foo
refers to".
*foo = 123;
or foo[0] = 123;
would be invalid.foo = &bar;
would be invalid.Here is an alternative that worked for me:
$('div#somediv').css({'width': '70%'});
Short answer:
$ ssh-keygen -p
This will then prompt you to enter the keyfile location, the old passphrase, and the new passphrase (which can be left blank to have no passphrase).
If you would like to do it all on one line without prompts do:
$ ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]
Important: Beware that when executing commands they will typically be logged in your ~/.bash_history
file (or similar) in plain text including all arguments provided (i.e. the passphrases in this case). It is, therefore, is recommended that you use the first option unless you have a specific reason to do otherwise.
Notice though that you can still use -f keyfile
without having to specify -P
nor -N
, and that the keyfile defaults to ~/.ssh/id_rsa
, so in many cases, it's not even needed.
You might want to consider using ssh-agent, which can cache the passphrase for a time. The latest versions of gpg-agent also support the protocol that is used by ssh-agent.
\r
is the ASCII Carriage Return (CR) character.
There are different newline conventions used by different operating systems. The most common ones are:
\r\n
);\n
);\r
).The \n\r
(LF+CR) looks unconventional.
edit: My reading of the Telnet RFC suggests that:
The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").
Hope it's working for you

// get no of pixels hidden above the the window
var scrollTop = $(window).scrollTop();
// get elements distance from top of window
var topBuffer = ((settings.topBoundary || 0) - scrollTop);
// update position if required
if (topBuffer >= 0) { top += topBuffer }
elem.css('top', top);
};
$(window).bind('scroll', setPosition);
setPosition();
});

You could open the file up and use StreamReader.ReadLine to read the file in line-by-line. Then you can use String.Split to break each line into pieces (use a \t delimiter) to extract the second number.
As the number of items is different you would need to search the string for the pattern 'item\*.ddj'.
To delete an item you could (for example) keep all of the file's contents in memory and write out a new file when the user clicks 'Save'.
A slight modification to @opsb's answer. We cant draw a full circle with this method. ie If we give (0, 360) it will not draw anything at all. So a slight modification made to fix this. It could be useful to display scores that sometimes reach 100%.

It sounds like you might just need to use a view. A view allows a query to be represented as a table so it, the view, can be queried.

Here's an example to make it clear how things work with GCC when static libraries are involved. So let's assume we have the following scenario:
myprog.o
- containing main()
function, dependent on libmysqlclient
libmysqlclient
- static, for the sake of the example (you'd prefer the shared library, of course, as the libmysqlclient
is huge); in /usr/local/lib
; and dependent on stuff from libz
libz
(dynamic)How do we link this? (Note: examples from compiling on Cygwin using gcc 4.3.4)
gcc -L/usr/local/lib -lmysqlclient myprog.o
# undefined reference to `_mysql_init'
# myprog depends on libmysqlclient
# so myprog has to come earlier on the command line
gcc myprog.o -L/usr/local/lib -lmysqlclient
# undefined reference to `_uncompress'
# we have to link with libz, too
gcc myprog.o -lz -L/usr/local/lib -lmysqlclient
# undefined reference to `_uncompress'
# libz is needed by libmysqlclient
# so it has to appear *after* it on the command line
gcc myprog.o -L/usr/local/lib -lmysqlclient -lz
# this works
If you like to get a list of all values of checked checkboxes (e.g. to send them as a list in one AJAX call to the server), you could get that list with:
var list = $("input[name='bla[]']:checked").map(function () {
return this.value;
}).get();
This is unrelated to UTF-8/16 (in general, although it does convert to UTF16 and the BE/LE part can be set w/ a single line), yet below is the fastest way to convert String to byte[]. For instance: good exactly for the case provided (hash code). String.getBytes(enc) is relatively slow.
static byte[] toBytes(String s){
byte[] b=new byte[s.length()*2];
ByteBuffer.wrap(b).asCharBuffer().put(s);
return b;
}
For every PostScript printer, one part of its driver is an ASCII file called PostScript Printer Description (PPD). PPDs are used in the CUPS printing system on Linux and Mac OS X as well even for non-PostScript printers.
Every PPD MUST, according to the PPD specification written by Adobe, contain definitions of a *ImageableArea (that's a PPD keyword) for each and every media sizes it can handle. That value is given for example as *ImageableArea Folio/8,25x13: "12 12 583 923"
for one printer in this office here, and *ImageableArea Folio/8,25x13: "0 0 595 935"
for the one sitting in the next room.
These figures mean "Lower left corner is at (12|12), upper right corner is at (583|923)" (where these figures are measured in points; 72pt == 1inch). Can you see that the first printer does print with a margin of 1/6 inch? -- Can you also see that the next one can even print borderless?
What you need to know is this: Even if the printer can do very small margins physically, if the PPD *ImageableArea
is set to a wider margin, the print data generated by the driver and sent to the printer will be clipped according to the PPD setting -- not by the printer itself.
These days more and more models appear on the market which can indeed print edge-to-edge. This is especially true for office laser printers. (Don't know about devices for the home use market.) Sometimes you have to enable that borderless mode with a separate switch in the driver settings, sometimes also on the device itself (front panel, or web interface).
Older models, for example HP's, define in their PPDs their margines quite generously, just to be on the supposedly "safe side". Very often HP used 1/3, 1/2 inch or more (like "24 24 588 768"
for Letter format). I remember having hacked HP PPDs and tuned them down to "6 6 606 786"
(1/12 inch) before the physical boundaries of the device kicked in and enforced a real clipping of the page image.
Now, PCL and other language printers are not that much different in their margin capabilities from PostScript models.
But of course, when it comes to printing of PDF docs, here you can nearly always choose "print to fit" or similarly named options. Even for a file that itself does not use any margins. That "fit" is what the PDF viewer reads from the driver, and the viewer then scales down the page to the *ImageableArea
.
I have encountered this issue in Angular 5 which still followed the link. The solution was to have the function return false
in order to prevent the page being refreshed:
<a href="" (click)="openChangePasswordForm()">Change expired password</a>
openChangePasswordForm(): boolean {
console.log("openChangePasswordForm called!");
return false;
}

angular.module('myApp')
.filter('isEmpty', function () {
var bar;
return function (obj) {
for (bar in obj) {
if (obj.hasOwnProperty(bar)) {
return false;
}
}
return true;
};

There are 2 ways of doing this
foreach($questions as $key => $question){
$questions[$key]['answers'] = $answers_model->get_answers_by_question_id($question['question_id']);
}
This way you save the key, so you can update it again in the main $questions
variable
or
foreach($questions as &$question){
Adding the &
will keep the $questions
updated. But I would say the first one is recommended even though this is shorter (see comment by Paystey)
Per the PHP foreach
documentation:
In order to be able to directly modify array elements within the loop precede $value with &. In that case the value will be assigned by reference.
I find the following link quite useful
http://blog.hubspot.com/marketing/calendar-invites-ical-outlook-google
I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:
My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.
private void startCreation(){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
Uri startDir = Uri.fromFile(new File("/sdcard"));
intent.setDataAndType(startDir,
"vnd.android.cursor.dir/lysesoft.andexplorer.file");
intent.putExtra("browser_filter_extension_whitelist", "*.csv");
intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
intent.putExtra("browser_title_background_color",
getText(R.string.browser_title_background_color));
intent.putExtra("browser_title_foreground_color",
getText(R.string.browser_title_foreground_color));
intent.putExtra("browser_list_background_color",
getText(R.string.browser_list_background_color));
intent.putExtra("browser_list_fontscale", "120%");
intent.putExtra("browser_list_layout", "2");
try{
ApplicationInfo info = getPackageManager()
.getApplicationInfo("lysesoft.andexplorer", 0 );
startActivityForResult(intent, PICK_REQUEST_CODE);
} catch( PackageManager.NameNotFoundException e ){
showInstallResultMessage(R.string.error_install_andexplorer);
} catch (Exception e) {
Log.w(TAG, e.getMessage());
}
}
This methos is just pick up a dialog and if user wants install the external application from market
private void showInstallResultMessage(int msg_id) {
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setMessage(getText(msg_id));
dialog.setButton(getText(R.string.button_ok),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
dialog.setButton2(getText(R.string.button_install),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
startActivity(intent);
finish();
}
});
dialog.show();
}
Another streaming command I've had good results with is piping the ffmpeg output to vlc to create a stream. If you don't have these installed, you can add them:
sudo apt install vlc ffmpeg
In the example I use an mpeg transport stream (ts) over http, instead of rtsp. I've tried both, but the http ts stream seems to work glitch-free on my playback devices.
I'm using a video capture HDMI>USB device that sets itself up on the video4linux2 driver as input. Piping through vlc must be CPU-friendly, because my old dual-core Pentium CPU is able to do the real-time encoding with no dropped frames. I've also had audio-sync issues with some of the other methods, where this method always has perfect audio-sync.
You will have to adjust the command for your device or file. If you're using a file as input, you won't need all that v4l2 and alsa stuff. Here's the ffmpeg|vlc command:
ffmpeg -thread_queue_size 1024 -f video4linux2 -input_format mjpeg -i /dev/video0 -r 30 -f alsa -ac 1 -thread_queue_size 1024 -i hw:1,0 -acodec aac -vcodec libx264 -preset ultrafast -crf 18 -s hd720 -vf format=yuv420p -profile:v main -threads 0 -f mpegts -|vlc -I dummy - --sout='#std{access=http,mux=ts,dst=:8554}'
For example, lets say your server PC IP is 192.168.0.10, then the stream can be played by this command:
ffplay http://192.168.0.10:8554
#or
vlc http://192.168.0.10:8554
What worked for me :
$where = '';
/* $this->db->like('ust.title',$query_data['search'])
->or_like('usr.f_name',$query_data['search'])
->or_like('usr.l_name',$query_data['search']);*/
$where .= "(ust.title like '%".$query_data['search']."%'";
$where .= " or usr.f_name like '%".$query_data['search']."%'";
$where .= "or usr.l_name like '%".$query_data['search']."%')";
$this->db->where($where);
$datas = $this->db->join(TBL_USERS.' AS usr','ust.user_id=usr.id')
->where_in('ust.id', $blog_list)
->select('ust.*,usr.f_name as f_name,usr.email as email,usr.avatar as avatar, usr.sex as sex')
->get_where(TBL_GURU_BLOG.' AS ust',[
'ust.deleted_at' => NULL,
'ust.status' => 1,
]);
I have to do this to create a query like this :
SELECT `ust`.*, `usr`.`f_name` as `f_name`, `usr`.`email` as `email`, `usr`.`avatar` as `avatar`, `usr`.`sex` as `sex` FROM `blog` AS `ust` JOIN `users` AS `usr` ON `ust`.`user_id`=`usr`.`id` WHERE (`ust`.`title` LIKE '%mer%' ESCAPE '!' OR `usr`.`f_name` LIKE '%lok%' ESCAPE '!' OR `usr`.`l_name` LIKE '%mer%' ESCAPE '!') AND `ust`.`id` IN('36', '37', '38') AND `ust`.`deleted_at` IS NULL AND `ust`.`status` = 1 ;
After importing stored procedure, you can create object of stored procedure pass the parameter like function
using (var entity = new FunctionsContext())
{
var DBdata = entity.GetFunctionByID(5).ToList<Functions>();
}
or you can also use SqlQuery
using (var entity = new FunctionsContext())
{
var Parameter = new SqlParameter {
ParameterName = "FunctionId",
Value = 5
};
var DBdata = entity.Database.SqlQuery<Course>("exec GetFunctionByID @FunctionId ", Parameter).ToList<Functions>();
}
The only way that worked for me - add the assembly to web.config
<compilation debug="true" targetFramework="4.5">
<assemblies>
<add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</assemblies>
</compilation>
Go to Solution properties ? Common Properties ? Startup Project and select Multiple startup projects.
Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Grid>
<Border Name="Border" Margin="0,0,0,0" Background="Transparent"

This is the example code taken from the PHP documentation here: https://www.php.net/manual/en/function.filemtime.php
// outputs e.g. somefile.txt was last changed: December 29 2002 22:16:23.
$filename = 'somefile.txt';
if (file_exists($filename)) {
echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
}
The code specifies the filename, then checks if it exists and then displays the modification time using filemtime()
.
filemtime()
takes 1 parameter which is the path to the file, this can be relative or absolute.
In case anyone is still struggling with this, as I was all morning today, I have found a solution that works for me:
Installation instructions:
git clone https://github.com/gstarnberger/uncompyle.git
cd uncompyle/
sudo ./setup.py install
Once the program is installed (note: it will be installed to your system-wide-accessible Python packages, so it should be in your $PATH
), you can recover your Python files like so:
uncompyler.py thank_goodness_this_still_exists.pyc > recovered_file.py
The decompiler adds some noise mostly in the form of comments, however I've found it to be surprisingly clean and faithful to my original code. You will have to remove a little line of text beginning with +++ near the end of the recovered file to be able to run your code.
The other answers were incomplete for me. I started from @Vladimir Novopashin answer and modified it. Here are the things, that I needed and bug I found:
.prop
instead of [prop]
. For example, formData.append('photos[0][file]', file)
didn't work on google chrome, while
formData.append('photos[0].file', file)
workedThe following code should work on IE11 and evergreen browsers.
function objectToFormData(obj, rootName, ignoreList) {
var formData = new FormData();
function appendFormData(data, root) {
if (!ignore(root)) {
root = root || '';
if (data instanceof File) {
formData.append(root, data);
} else if (Array.isArray(data)) {
for (var i = 0; i < data.length; i++) {
appendFormData(data[i], root + '[' + i + ']');
}
} else if (typeof data === 'object' && data) {
for (var key in data) {
if (data.hasOwnProperty(key)) {
if (root === '') {
appendFormData(data[key], key);
} else {
appendFormData(data[key], root + '.' + key);
}
}
}
} else {
if (data !== null && typeof data !== 'undefined') {
formData.append(root, data);
}
}
}
}
function ignore(root){
return Array.isArray(ignoreList)
&& ignoreList.some(function(x) { return x === root; });
}
appendFormData(obj, rootName);
return formData;
}
Something like this should do the trick (However, read after the snippet for more info)
CREATE PROCEDURE GetFilteredData()
BEGIN
DECLARE bDone INT;
DECLARE var1 CHAR(16); -- or approriate type
DECLARE Var2 INT;
DECLARE Var3 VARCHAR(50);
DECLARE curs CURSOR FOR SELECT something FROM somewhere WHERE some stuff;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;
DROP TEMPORARY TABLE IF EXISTS tblResults;
CREATE TEMPORARY TABLE IF NOT EXISTS tblResults (
--Fld1 type,
--Fld2 type,
--...
);
OPEN curs;
SET bDone = 0;
REPEAT
FETCH curs INTO var1,, b;
IF whatever_filtering_desired
-- here for whatever_transformation_may_be_desired
INSERT INTO tblResults VALUES (var1, var2, var3 ...);
END IF;
UNTIL bDone END REPEAT;
CLOSE curs;
SELECT * FROM tblResults;
END
A few things to consider...
Concerning the snippet above:
More generally: trying to avoid needing a cursor.
I purposely named the cursor variable curs[e], because cursors are a mixed blessing. They can help us implement complicated business rules that may be difficult to express in the declarative form of SQL, but it then brings us to use the procedural (imperative) form of SQL, which is a general feature of SQL which is neither very friendly/expressive, programming-wise, and often less efficient performance-wise.
Maybe you can look into expressing the transformation and filtering desired in the context of a "plain" (declarative) SQL query.
Validation aside, the fact remains that encoding certain characters is important to an HTML document so that it can render properly and safely as a web page.
Encoding &
as &
under all circumstances, for me, is an easier rule to live by, reducing the likelihood of errors and failures.
Compare the following: which is easier? which is easier to bugger up?
(with a grain of salt, please ;) )
volt & amp
amp&volt
volt&
??
For example, I will create a table called users
as below and give a column named date
a default value NOW()
create table users_parent (
user_id varchar(50),
full_name varchar(240),
login_id_1 varchar(50),
date timestamp NOT NULL DEFAULT NOW()
);
Thanks
You should use the optional argument indent
.
header, output = client.request(twitterRequest, method="GET", body=None,
headers=None, force_auth_header=True)
# now write output to a file
twitterDataFile = open("twitterData.json", "w")
# magic happens here to make it pretty-printed
twitterDataFile.write(simplejson.dumps(simplejson.loads(output), indent=4, sort_keys=True))
twitterDataFile.close()
YOU HAVE TO BE CAREFUL when you initialize state
from props
in constructor. Even if props
changed to new one, the state wouldn't be changed because mount never happen again.
So getDerivedStateFromProps
exists for that.
class FirstComponent extends React.Component {
state = {
description: ""
};
static getDerivedStateFromProps(nextProps, prevState) {
if (prevState.description !== nextProps.description) {
return { description: nextProps.description };
}
return null;
}
render() {
const {state: {description}} = this;
return (
<input type="text" value={description} />
);
}
}
Or use key
props as a trigger to initialize:
class SecondComponent extends React.Component {
state = {
// initialize using props
};
}
<SecondComponent key={something} ... />
In the code above, if something
changed, then SecondComponent
will re-mount as a new instance and state
will be initialized by props
.
All you need to do to solve the problem is... to make sure your version of Java is the same for both compiling and running. No matter what tools or IDEs you are using.
You cannot provide your own implementation for the setter when using automatic properties. In other words, you should either do:
public int Hour { get;set;} // Automatic property, no implementation
or provide your own implementation for both the getter and setter, which is what you want judging from your example:
public int Hour
{
get { return hour; }
set
{
if (value < MIN_HOUR)
{
hour = 0;
MessageBox.Show("Hour value " + value.ToString() + " cannot be negative. Reset to " + MIN_HOUR.ToString(),
"Invalid Hour", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
else
{
//take the modulus to ensure always less than 24 hours
//works even if the value is already within range, or value equal to 24
hour = value % MAX_HOUR;
}
}
}
Convert your image file to Base64 string with a tool like this and then replace the YourBase64StringHere
placeholder in the below snippet with your string and put the line in your HTML head section:
<link href="data:image/x-icon;base64,YourBase64StringHere" rel="icon" type="image/x-icon" />
This will work 100% in browsers.

Watch out for the trap I got into: When checking if certain value is not present in an array, you shouldn't do:
SELECT value_variable != ANY('{1,2,3}'::int[])
but use
SELECT value_variable != ALL('{1,2,3}'::int[])
instead.
I reached the point that I set, up to max_iter=1200000
on my LinearSVC
classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False
and leaving max_iter
to its default.
With LogisticRegression(solver='lbfgs')
classifier, you should increase max_iter
. Mine have reached max_iter=7600
before the "ConvergenceWarning" disappears when training with large dataset's features.
In a nutshell, a schema is the definition for the entire database, so it includes tables, views, stored procedures, indexes, primary and foreign keys, etc.
Be careful though, for those who using pip install --user some_pkg
inside a virtual environment.
$ path/to/python -m venv ~/my_py_venv
$ source ~/my_py_venv/bin/activate
(my_py_venv) $ pip install --user some_pkg
(my_py_venv) $ pip uninstall some_pkg
WARNING: Skipping some_pkg as it is not installed.
(my_py_venv) $ pip list
# Even `pip list` will not properly list the `some_pkg` in this case
In this case, you have to deactivate the current virtual environment, then use the corresponding python
/pip
executable to list or uninstall the user site packages:
(my_py_venv) $ deactivate
$ path/to/python -m pip list
$ path/to/python -m pip uninstall some_pkg
Note that this issue was reported few years ago. And it seems that the current conclusion is: --user
is not valid inside a virtual env's pip
, since a user location doesn't really make sense for a virtual environment.
Yes the set of instructions above are outdated. For the new GitHub the Settings button must be clicked.
Also the person you try to add as a collaborator must have an existing GitHub account. In other words he should have signed up on GitHub first because it is not possible to send collaboration requests merely by typing in the email address of the collaborator.
As @jethro said, splitext
is the neat way to do it. But in this case, it's pretty easy to split it yourself, since the extension must be the part of the filename coming after the final period:
filename = '/home/user/somefile.txt'
print( filename.rsplit( ".", 1 )[ 0 ] )
# '/home/user/somefile'
The rsplit
tells Python to perform the string splits starting from the right of the string, and the 1
says to perform at most one split (so that e.g. 'foo.bar.baz'
-> [ 'foo.bar', 'baz' ]
). Since rsplit
will always return a non-empty array, we may safely index 0
into it to get the filename minus the extension.
Please make sure that all properties are both the getter and setter. In case, any property is getter only, it will cause the reverting the List to original data as the JSON string is typed.
Please refer to the following code snippet for the same: Model:
public class Person
{
public int ID { get; set; }
// following 2 lines are cause of error
//public string Name { get { return string.Format("{0} {1}", First, Last); } }
//public string Country { get { return Countries[CountryID]; } }
public int CountryID { get; set; }
public bool Active { get; set; }
public string First { get; set; }
public string Last { get; set; }
public DateTime Hired { get; set; }
}
public class ModelObj
{
public string Str { get; set; }
public List<Person> Persons { get; set; }
}
Controller:
[HttpPost]
public ActionResult Index(FormCollection collection)
{
var data = new ModelObj();
data.Str = (string)collection.GetValue("Str").ConvertTo(typeof(string));
var personsString = (string)collection.GetValue("Persons").ConvertTo(typeof(string));
using (var textReader = new StringReader(personsString))
{
using (var reader = new JsonTextReader(textReader))
{
data.Persons = new JsonSerializer().Deserialize(reader, typeof(List<Person>)) as List<Person>;
}
}
return View(data);
}
When you run the Windows Command Prompt, and type in python
, it starts the Python interpreter.
Typing it again tries to interpret python
as a variable, which doesn't exist and thus won't work:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> print("interpreter has started")
interpreter has started
>>> quit() # leave the interpreter, and go back to the command line
C:\Users\USER>
If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python
is interpreted as a variable, which you have not defined.
Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:
class Test {
Dictionary<int,String> entities;
public String getEntity(int code) {
return this.entities[code];
}
}
If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).
What worked for me is I:
Note about restarting Firefox: When I do start it very soon after closing it, it often has a file access problem, which requires me to delete places.sqlite and places.sqlite-journal in C:\WINDOWS\Application Data\Mozilla\Firefox\Profiles\n18091xv.default. This causes me to lose my history, plus bookmarks have to be restored from a backup each time this happens. I wait from five to ten minutes or more to avoid this hassle.

This is one approach:
from xlrd import open_workbook

def __init__(self, id, dsp_name, dsp_code, hub_code, pin_code, pptl):
self.id = id
self.dsp_name = dsp_name
self.dsp_code = dsp_code
self.hub_code = hub_code
self.pin_code = pin_code
self.pptl = pptl
def __str__(self):
return("Arm object:\n"
" Arm_id = {0}\n"
" DSPName = {1}\n"
" DSPCode = {2}\n"
" HubCode = {3}\n"
" PinCode = {4} \n"
" PPTL = {5}"
.format(self.id, self.dsp_name, self.dsp_code,
self.hub_code, self.pin_code, self.pptl))
wb = open_workbook('sample.xls')
for sheet in wb.sheets():
number_of_rows = sheet.nrows
number_of_columns = sheet.ncols
items = []
rows = []
for row in range(1, number_of_rows):
values = []
for col in range(number_of_columns):
value = (sheet.cell(row,col).value)
try:
value = str(int(value))
except ValueError:
pass
finally:
values.append(value)
item = Arm(*values)
items.append(item)
for item in items:
print item
print("Accessing one single value (eg. DSPName): {0}".format(item.dsp_name))
print
You don't have to use a custom class, you can simply take a dict()
. If you use a class however, you can access all values via dot-notation, as you see above.

Commit #62736046 added ".container-fluid variation for full-width containers and layouts".
This does not work for existing jobs, however there is Jenkins job builder.
This allows one to keep job definitions in yaml files and in a git repo which is very portable.
You could use a nested Any()
for this check which is available on any Enumerable
:
bool hasMatch = myStrings.Any(x => parameters.Any(y => y.source == x));
Faster performing on larger collections would be to project parameters
to source
and then use Intersect
which internally uses a HashSet<T>
so instead of O(n^2) for the first approach (the equivalent of two nested loops) you can do the check in O(n) :
bool hasMatch = parameters.Select(x => x.source)
.Intersect(myStrings)
.Any();
Also as a side comment you should capitalize your class names and property names to conform with the C# style guidelines.

None of these answers with the use of HEAD@{1}
worked out for me, so here's my solution:
git reflog

git reset --soft c296452

$query1 = mysqli_query($aVar, "SELECT name1 FROM users
ORDER BY RAND()
LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];
Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.
One important difference not mentioned above which might catch you out is that System.Timers.Timer
silently swallows exceptions, whereas System.Threading.Timer
doesn't.
For example:
var timer = new System.Timers.Timer { AutoReset = false };
timer.Elapsed += (sender, args) =>
{
var z = 0;
var i = 1 / z;
};
timer.Start();
vs
var timer = new System.Threading.Timer(x =>
{
var z = 0;
var i = 1 / z;
}, null, 0, Timeout.Infinite);

Select the whole sheet and change the font size on your data to something small, like 10 or 12. When you zoom in to view the data you will find that the drop down box entries are now visible.
To emphasize, the issue is not so much with the size of the font in the drop down, it is the relative size between drop down and data display font sizes.
I came across this question, and figured out sorting the iterators directly would be a way to sort the values and keep track of indices; There is no need to define an extra container of pair
s of ( value, index ) which is helpful when the values are large objects; The iterators provides the access to both the value and the index:
/*
* a function object that allows to compare
* the iterators by the value they point to
*/
template < class RAIter, class Compare >
class IterSortComp
{
public:
IterSortComp ( Compare comp ): m_comp ( comp ) { }
inline bool operator( ) ( const RAIter & i, const RAIter & j ) const
{
return m_comp ( * i, * j );
}
private:
const Compare m_comp;
};
template <class INIter, class RAIter, class Compare>
void itersort ( INIter first, INIter last, std::vector < RAIter > & idx, Compare comp )
{
idx.resize ( std::distance ( first, last ) );
for ( typename std::vector < RAIter >::iterator j = idx.begin( ); first != last; ++ j, ++ first )
* j = first;
std::sort ( idx.begin( ), idx.end( ), IterSortComp< RAIter, Compare > ( comp ) );
}
as for the usage example:
std::vector < int > A ( n );
// populate A with some random values
std::generate ( A.begin( ), A.end( ), rand );
std::vector < std::vector < int >::const_iterator > idx;
itersort ( A.begin( ), A.end( ), idx, std::less < int > ( ) );
now, for example, the 5th smallest element in the sorted vector would have value **idx[ 5 ]
and its index in the original vector would be distance( A.begin( ), *idx[ 5 ] )
or simply *idx[ 5 ] - A.begin( )
.
I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.
Sure you could use $var=0; $var++
in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++
would probably throw an error.
I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

If you want to use less code, you can also use the norm
in the stats
package (the 'F' stands for Forbenius, which is the Euclidean norm):
norm(matrix(x1-x2), 'F')
While this may look a bit neater, it's not faster. Indeed, a quick test on very large vectors shows little difference, though so12311's method is slightly faster. We first define:
set.seed(1234)
x1 <- rnorm(300000000)
x2 <- rnorm(300000000)
Then testing for time yields the following:
> system.time(a<-sqrt(sum((x1-x2)^2)))
user system elapsed
1.02 0.12 1.18

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection
for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).
Hence, you can get the value of merged cells in range B4:B11
in several ways:
Range("B4").Value
Range("B4:B11").Cells(1).Value
Range("B4:B11").Cells(1,1).Value
You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty
.
Also note that Range("B4:B11").Value
won't work (raises an execution error number 13 if you try to Debug.Print
it) because it returns an array.
No, that's not really possible, as
The goal of the MD5 and its family of hashing functions is
Think that you can get the MD5 of any string, even very long. And the MD5 is only 16 bytes long (32 if you write it in hexa to store or distribute it more easily). If you could reverse them, you'd have a magical compacting scheme.
This being said, as there aren't so many short strings (passwords...) used in the world, you can test them from a dictionary (that's called "brute force attack") or even google for your MD5. If the word is common and wasn't salted, you have a reasonable chance to succeed...
Maybe the method document.createElement();

I'll suggest different approach, If the order of the items inside the list is not important at extraction (and each item should be selected only once), then instead of a List
you can use a ConcurrentBag
which is a thread-safe, unordered collection of objects:
var bag = new ConcurrentBag<string>();
bag.Add("Foo");
bag.Add("Boo");
bag.Add("Zoo");
The EventHandler:
string result;
if (bag.TryTake(out result))
{
MessageBox.Show(result);
}
The TryTake
will attempt to extract an "random" object from the unordered collection.
you can try this... ALTER TABLE Your_Table ADD table_ID int NOT NULL PRIMARY KEY auto_increment;
To add some clarification and directly address the question above, there are several classes of characters that cause problems for URLs and URIs.
There are some characters that are disallowed and should never appear in a URL/URI, reserved characters (described below), and other characters that may cause problems in some cases, but are marked as "unwise" or "unsafe". Explanations for why the characters are restricted are clearly spelled out in RFC-1738 (URLs) and RFC-2396 (URIs). Note the newer RFC-3986 (update to RFC-1738) defines the construction of what characters are allowed in a given context but the older spec offers a simpler and more general description of which characters are not allowed with the following rules.
Excluded US-ASCII Characters disallowed within the URI syntax:
control = <US-ASCII coded characters 00-1F and 7F hexadecimal>
space = <US-ASCII coded character 20 hexadecimal>
delims = "<" | ">" | "#" | "%" | <">
The character "#" is excluded because it is used to delimit a URI from a fragment identifier. The percent character "%" is excluded because it is used for the encoding of escaped characters. In other words, the "#" and "%" are reserved characters that must be used in a specific context.
List of unwise characters are allowed but may cause problems:
unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`"
Characters that are reserved within a query component and/or have special meaning within a URI/URL:
reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | ","
The "reserved" syntax class above refers to those characters that are allowed within a URI, but which may not be allowed within a particular component of the generic URI syntax. Characters in the "reserved" set are not reserved in all contexts. The hostname, for example, can contain an optional username so it could be something like ftp://user@hostname/
where the '@' character has special meaning.
Here is an example of a URL that has invalid and unwise characters (e.g. '$', '[', ']') and should be properly encoded:
http://mw1.google.com/mw-earth-vectordb/kml-samples/gp/seattle/gigapxl/$[level]/r$[y]_c$[x].jpg
Some of the character restrictions for URIs and URLs are programming language-dependent. For example, the '|' (0x7C) character although only marked as "unwise" in the URI spec will throw a URISyntaxException in the Java java.net.URI constructor so a URL like http://api.google.com/q?exp=a|b
is not allowed and must be encoded instead as http://api.google.com/q?exp=a%7Cb
if using Java with a URI object instance.
The upcoming change is for chinese, arabic domain names not URIs. The internationalised URIs are called IRIs and are defined in RFC 3987. However, having said that I'd recommend not doing this yourself but relying on an existing, tested library since there are lots of choices of URI encoding/decoding and what are considered safe by specification, versus what are safe by actual use (browsers).
You could use the {display: inline-flex;} this would produce this: inline-flex
Notepad++ changed in the past couple of years, and it requires a few extra steps to set up a dark theme.

I haven't played around with it much but eclipse/pydev feels nice.
You get this error when declaring a forward reference inside the wrong namespace thus declaring a new type without defining it. For example:
namespace X
{
namespace Y
{
class A;
void func(A* a) { ... } // incomplete type here!
}
}
...but, in class A was defined like this:
namespace X
{
class A { ... };
}
Thus, A was defined as X::A
, but I was using it as X::Y::A
.
The fix obviously is to move the forward reference to its proper place like so:
namespace X
{
class A;
namespace Y
{
void func(X::A* a) { ... } // Now accurately referencing the class`enter code here`
}
}
Necromancing, just in case all the links go dark:
Add a group to your report
Also, be advised to set the sort order of the group expression here, so the tabs will be alphabetically sorted (or however you want it sorted).
Set the page break in the group properties
Now you need to set the PageName
of the Tablix Member (group), NOT the PageName
of the Tablix itselfs.
If you got the right object, if will say "Tablix Member" (Tablix-Element in German) in the title box of the properties grid. If it's the wrong object, it will say only "table/tablix" (without member) in the property grid's title box.
Note: If you get the tablix instead of the tablix member, it will put the same tab name in every tab, followed by a (tabNum)
! If that happens, you now know what the problem is.
If you use the new querySelectorAll you can call forEach directly.
document.querySelectorAll('.edit').forEach(function(button) {
// Now do something with my button
});
Per the comment below. nodeLists do not have a forEach function.
If using this with babel you can add Array.from
and it will convert non node lists to a forEach array. Array.from
does not work natively in browsers below and including IE 11.
Array.from(document.querySelectorAll('.edit')).forEach(function(button) {
// Now do something with my button
});
At our meetup last night I discovered another way to handle node lists not having forEach
[...document.querySelectorAll('.edit')].forEach(function(button) {
// Now do something with my button
});

One more made from the core jQuery functionality(it could be better):
function blink( el ) {
if (!el) {
el = this
}
$(el).animate( { opacity: 0.5 },1200, function() {
$(this).animate( {opacity: 1 }, 1200, blink );
} );
}
You can tweak the animation opacity change(0.5- 1) and delay(1200) to get a better "blink". This one is less annoying than the blink of the 90es :-)

git rebase --abort

First and major difference between trustStore and keyStore is that trustStore is used by TrustManager to determine whether remote connection should be trusted, keyStore is used from KeyManager deciding which authentication credentials should be sent to the remote host for authentication during SSL handshake.
Another difference is that keyStore theoretically contains private keys required only if you are running a Server in SSL connection or you have enabled client authentication on server side and on the other hand trustStore stores public key or certificates from CA (Certificate Authorities) which are used to trust remote party or SSL connection.
In fact you can store in the same file both private and public keys, given that the the tool to manage those file is the same (keytool), so you could use a single file for both the purposes, but you probably should not.
At least on my Mac OSX the default keyStore is ${user.home}/.keystore
, and the default trustStore is /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security/cacerts
.
If you want to override them you should add the JVM parameters
-Djavax.net.ssl.keyStore /path/to/keyStore
or
-Djavax.net.ssl.trustStore /path/to/trustStore
. You might also
need to set the keyStore password in case of
java.security.UnrecoverableKeyException: Password must not be
null
, using the parameter
-Djavax.net.ssl.trustStorePassword=password
or -Djavax.net.ssl.trustStorePassword=password

Why Server.Transfer
? Response.Redirect(Request.RawUrl)
would get you what you need.
Default arguments must be specified with the first occurrence of the function name—typically, in the function prototype. If the function prototype is omitted because the function definition also serves as the prototype, then the default arguments should be specified in the function header.
you can only focus required textbox an insert the text there. there is no way to find out where focus is AFAIK (maybe interating over all DOM nodes?).

A few things here...
If you want to call a function when the onclick event happens, you'll just want the function name plus the parameters.
Then if your parameters are a variable (which they look like they are), then you won't want quotes around them. Not only that, but if these are global variables, you'll want to add in "window." before that, because that's the object that holds all global variables.
Lastly, if these parameters aren't variables, you'll want to exclude the slashes to escape those characters. Since the value of onclick is wrapped by double quotes, single quotes won't be an issue. So your answer will look like this...
<a href=# onclick="ReAssign('valuationId', window.user)">Re-Assign</a>
There are a few extra things to note here, if you want more than a quick solution.
You looked like you were trying to use the + operator to combine strings in HTML. HTML is a scripting language, so when you're writing it, the whole thing is just a string itself. You can just skip these from now on, because it's not code your browser will be running (just a whole bunch of stuff, and anything that already exists is what has special meaning by the browser).
Next, you're using an anchor tag/link that doesn't actually take the user to another website, just runs some code. I'd use something else other than an anchor tag, with the appropriate CSS to format it to look the way you want. It really depends on the setting, but in many cases, a span tag will do. Give it a class (like class="runjs") and have a rule of CSS for that. To get it to imitate a link's behavior, use this:
.runjs {
cursor: pointer;
text-decoration: underline;
color: blue;
}
This lets you leave out the href attribute which you weren't using anyways.
Last, you probably want to use JavaScript to set the value of this link's onclick attribute instead of hand writing it. It keeps your page cleaner by keeping the code of your page separate from what the structure of your page. In your class, you could change all these links like this...
var links = document.getElementsByClassName('runjs');
for(var i = 0; i < links.length; i++)
links[i].onclick = function() { ReAssign('valuationId', window.user); };
While this won't work in some older browsers (because of the getElementsByClassName method), it's just three lines and does exactly what you're looking for. Each of these links has an anonymous function tied to them meaning they don't have any variable tied to them except that tag's onclick value. Plus if you wanted to, you could include more lines of code this way, all grouped up in one tidy location.

$("#testID #testID2").removeClass("test2").addClass("test3");
Because you have assigned an id to img too, you can simply do this too:
$("#testID2").removeClass("test2").addClass("test3");
And finally, you can do this too:
$("#testID img").removeClass("test2").addClass("test3");

Look at Float.intBitsToFloat
and Double.longBitsToDouble
, which sort of explain how bits correspond to floating-point numbers. In particular, the bits of a normal float
look something like
s * 2^exp * 1.ABCDEFGHIJKLMNOPQRSTUVW
where A...W are 23 bits -- 0s and 1s -- representing a fraction in binary -- s is +/- 1, represented by a 0 or a 1 respectively, and exp is a signed 8-bit integer.

Range("C2:C" & lastrow).Select

You shouldn't design your application based on specific lifetimes of access tokens. Just assume they are (very) short lived.
However, after a successful completion of the OAuth2 installed application flow, you will get back a refresh token. This refresh token never expires, and you can use it to exchange it for an access token as needed. Save the refresh tokens, and use them to get access tokens on-demand (which should then immediately be used to get access to user data).
EDIT: My comments above notwithstanding, there are two easy ways to get the access token expiration time:
expires_in
)when you exchange your refresh token (using /o/oauth2/token endpoint). More details.There is also an API that returns the remaining lifetime of the access_token:
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}
This will return a json array that will contain an expires_in
parameter, which is the number of seconds left in the lifetime of the token.
maybe you could use AsyncStorage setItem and getItem...and store the data as string, then use the json parser for convert it again to json...

If your solution doesn't have to be general, i.e. only needs to work for strings like your example, you could do:
var1=$(echo $STR | cut -f1 -d-)
var2=$(echo $STR | cut -f2 -d-)
I chose cut
here because you could simply extend the code for a few more variables...
It is just a hint for the Service Provider on what to expect from the NameID returned by the Identity Provider. It can be:
unspecified
emailAddress
– e.g. [email protected]
X509SubjectName
– e.g. CN=john,O=Company Ltd.,C=US
WindowsDomainQualifiedName
– e.g. CompanyDomain\John
kerberos
– e.g. john@realm
entity
– this one in used to identify entities that provide SAML-based services and looks like a URIpersistent
– this is an opaque service-specific identifier which must include a pseudo-random value and must not be traceable to the actual user, so this is a privacy feature.transient
– opaque identifier which should be treated as temporary.You can also rely on the default value of the constructor if you wish to create a typed array:
> $a = new-object bool[] 5
> $a
False
False
False
False
False
The default value of a bool is apparently false so this works in your case. Likewise if you create a typed int[] array, you'll get the default value of 0.
Another cool way that I use to initialze arrays is with the following shorthand:
> $a = ($false, $false, $false, $false, $false)
> $a
False
False
False
