Every object has to be named inside the parent object:
{ "data": {
"stuff": {
"onetype": [
{ "id": 1, "name": "" },
{ "id": 2, "name": "" }
],
"othertype": [
{ "id": 2, "xyz": [-2, 0, 2], "n": "Crab Nebula", "t": 0, "c": 0, "d": 5 }
]
},
"otherstuff": {
"thing":
[[1, 42], [2, 2]]
}
}
}
So you cant declare an object like this:
var obj = {property1, property2};
It has to be
var obj = {property1: 'value', property2: 'value'};
The latest google api docs document how to write to a spreadsheet with python but it's a little difficult to navigate to. Here is a link to an example of how to append.

$('input[type="submit"]').click(function(){
$(this).css('color','red');
});
Use class, Demo:- http://jsfiddle.net/BX6Df/
$('input[type="submit"]').click(function(){
$(this).addClass('red');
});
if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/
$('input[type="submit"]').click(function(){
$(this).toggleClass('red');
});
.red
{
background-color:red;
}
Updated answer for your comment.
$('input[type="submit"]').click(function(){
$('input[type="submit"].red').removeClass('red')
$(this).addClass('red');
});
How about wait-notify
private Boolean bool = true;
private final Object lock = new Object();
private Boolean getChange(){
synchronized(lock){
while (bool) {
bool.wait();
}
}
return bool;
}
public void setChange(){
synchronized(lock){
bool = false;
bool.notify();
}
}
Change
\bibliographystyle{plain}
to
\bibliographystyle{ieeetr}
Then rebuild it a few times to replace the .aux
and .bbl
files that were made when you used the plain style.
Or simply delete the .aux
and .bbl
files and rebuild.
If you use MiKTeX you shouldn't need to download anything extra.
You could try using df['column'].str.
and then use any string function. Pandas documentation includes those like split
smux.py
allows you to simply list the commands you want in each pane, prefixed with a line containing three dashes.
Here's an example smux file that starts three panes.
---
echo "This is pane 1."
---
cd /tmp
git clone https://github.com/hq6/smux
cd smux
less smux.py
---
man tmux
If you put this in a file called Sample.smux
, you can then run the following to launch.
pip3 install smux.py
smux.py Sample.smux

The best way is you should destroy the slick slider after reinitializing it.
function slickCarousel() {
$('.skills_section').slick({
infinite: true,
slidesToShow: 3,
slidesToScroll: 1
});
}
function destroyCarousel() {
if ($('.skills_section').hasClass('slick-initialized')) {
$('.skills_section').slick('destroy');
}
}
$.ajax({
type: 'get',
url: '/public/index',
dataType: 'script',
data: data_send,
success: function() {
destroyCarousel()
slickCarousel();
}
});
If you have background on that element, then, adding padding would be useless.
So, in this case, you can use background-clip: content-box; or outline-offset
Explanation: If you use wrapper, then it would be simple to separate the background from border. But if you want to style the same element, which has a background, no matter how much padding you would add, there would be no space between background and border, unless you use background-clip or outline-offset
I crammed everything into one line (bad I know) and had no troubles with it:
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"test"
ofType:@"html"]
isDirectory:NO]]];
This is a rather restricted case, but judging from the comments I've received I think it's worth noting.
I've seen people in the past use maps in the form of
map< const key, const val> Map;
to evade cases of accidental value overwriting, but then go ahead writing in some other bits of code:
const_cast< T >Map[]=val;
Their reason for doing this as I recall was because they were sure that in these certain bits of code they were not going to be overwriting map values; hence, going ahead with the more 'readable' method []
.
I've never actually had any direct trouble from the code that was written by these people, but I strongly feel up until today that risks - however small - should not be taken when they can be easily avoided.
In cases where you're dealing with map values that absolutely must not be overwritten, use insert
. Don't make exceptions merely for readability.
The Question is not private or public, the question is: How is it invoked and which AOP implementation you use!
If you use (default) Spring Proxy AOP, then all AOP functionality provided by Spring (like @Transactional
) will only be taken into account if the call goes through the proxy. -- This is normally the case if the annotated method is invoked from another bean.
This has two implications:
@Transactional
Annotation is not taken into account.@See Spring Reference: Chapter 9.6 9.6 Proxying mechanisms
IMHO you should use the aspectJ mode, instead of the Spring Proxies, that will overcome the problem. And the AspectJ Transactional Aspects are woven even into private methods (checked for Spring 3.0).
In addition to excellent answers already provided, there are some cases where explicit implementation is REQUIRED for the compiler to be able to figure out what is required. Take a look at IEnumerable<T>
as a prime example that will likely come up fairly often.
Here's an example:
public abstract class StringList : IEnumerable<string>
{
private string[] _list = new string[] {"foo", "bar", "baz"};
// ...
#region IEnumerable<string> Members
public IEnumerator<string> GetEnumerator()
{
foreach (string s in _list)
{ yield return s; }
}
#endregion
#region IEnumerable Members
IEnumerator IEnumerable.GetEnumerator()
{
return this.GetEnumerator();
}
#endregion
}
Here, IEnumerable<string>
implements IEnumerable
, hence we need to too. But hang on, both the generic and the normal version both implement functions with the same method signature (C# ignores return type for this). This is completely legal and fine. How does the compiler resolve which to use? It forces you to only have, at most, one implicit definition, then it can resolve whatever it needs to.
ie.
StringList sl = new StringList();
// uses the implicit definition.
IEnumerator<string> enumerableString = sl.GetEnumerator();
// same as above, only a little more explicit.
IEnumerator<string> enumerableString2 = ((IEnumerable<string>)sl).GetEnumerator();
// returns the same as above, but via the explicit definition
IEnumerator enumerableStuff = ((IEnumerable)sl).GetEnumerator();
PS: The little piece of indirection in the explicit definition for IEnumerable works because inside the function the compiler knows that the actual type of the variable is a StringList, and that's how it resolves the function call. Nifty little fact for implementing some of the layers of abstraction some of the .NET core interfaces seem to have accumulated.
This is not an plus, but the sign for the binary operator XOR
a b a XOR b
0 0 0
0 1 1
1 0 1
1 1 0
This is borderline programming, but look into using tr:
$ echo "this is just a test" | tr -s ' ' | tr ' ' '_'
Should do it. The first invocation squeezes the spaces down, the second replaces with underscore. You probably need to add TABs and other whitespace characters, this is for spaces only.
You could also just put the first SELECT in a subquery. Since most optimizers will fold it into a constant anyway, there should not be a performance hit on this.
Incidentally, since you are using a predicate like this:
CONVERT(...) = CONVERT(...)
that predicate expression cannot be optimized properly or use indexes on the columns reference by the CONVERT() function.
Here is one way to make the original query somewhat better:
DECLARE @ooDate datetime
SELECT @ooDate = OO.Date FROM OLAP.OutageHours AS OO where OO.OutageID = 1
SELECT
COUNT(FF.HALID)
FROM
Outages.FaultsInOutages AS OFIO
INNER JOIN Faults.Faults as FF ON
FF.HALID = OFIO.HALID
WHERE
FF.FaultDate >= @ooDate AND
FF.FaultDate < DATEADD(day, 1, @ooDate) AND
OFIO.OutageID = 1
This version could leverage in index that involved FaultDate, and achieves the same goal.
Here it is, rewritten to use a subquery to avoid the variable declaration and subsequent SELECT.
SELECT
COUNT(FF.HALID)
FROM
Outages.FaultsInOutages AS OFIO
INNER JOIN Faults.Faults as FF ON
FF.HALID = OFIO.HALID
WHERE
CONVERT(varchar(10), FF.FaultDate, 126) = (SELECT CONVERT(varchar(10), OO.Date, 126) FROM OLAP.OutageHours AS OO where OO.OutageID = 1) AND
OFIO.OutageID = 1
Note that this approach has the same index usage issue as the original, because of the use of CONVERT() on FF.FaultDate. This could be remedied by adding the subquery twice, but you would be better served with the variable approach in this case. This last version is only for demonstration.
Regards.
You need to do it like this,
void Yourfunction(List<DateTime> dates )
{
}
Your curtime
variable holds the number of seconds since the epoch. If you get one before and one after, the later one minus the earlier one is the elapsed time in seconds. You can subtract time_t
values just fine.
Swift 5.0
// Standard State
myButton.setTitle("Title", for: .normal)
Use this:
static int RandomNumber(int min, int max)
{
Random random = new Random(); return random.Next(min, max);
}
This is example for you to modify and use in your application.
The simple answer to your question is that there is no Annotation-Inheritance in Java. However, there is a way to use the Spring annotations in a way that I think will help solve your problem.
@RequestMapping is supported at both the type level and at the method level.
When you put @RequestMapping
at the type level, most of the attributes are 'inherited' for each method in that class. This is mentioned in the Spring reference documentation. Look at the api docs for details on how each attribute is handled when adding @RequestMapping
to a type. I've summarized this for each attribute below:
name
: Value at Type level is concatenated with value at method level using '#' as a separator.value
: Value at Type level is inherited by method.path
: Value at Type level is inherited by method.method
: Value at Type level is inherited by method.params
: Value at Type level is inherited by method.headers
: Value at Type level is inherited by method.consumes
: Value at Type level is overridden by method.produces
: Value at Type level is overridden by method.Here is a brief example Controller that showcases how you could use this:
package com.example;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping(path = "/",
consumes = MediaType.APPLICATION_JSON_VALUE,
produces = MediaType.APPLICATION_JSON_VALUE,
method = {RequestMethod.GET, RequestMethod.POST})
public class JsonProducingEndpoint {
private FooService fooService;
@RequestMapping(path = "/foo", method = RequestMethod.POST)
public String postAFoo(@RequestBody ThisIsAFoo theFoo) {
fooService.saveTheFoo(theFoo);
return "http://myservice.com/foo/1";
}
@RequestMapping(path = "/foo/{id}", method = RequestMethod.GET)
public ThisIsAFoo getAFoo(@PathVariable String id) {
ThisIsAFoo foo = fooService.getAFoo(id);
return foo;
}
@RequestMapping(path = "/foo/{id}", produces = MediaType.APPLICATION_XML_VALUE, method = RequestMethod.GET)
public ThisIsAFooXML getAFooXml(@PathVariable String id) {
ThisIsAFooXML foo = fooService.getAFoo(id);
return foo;
}
}
declare @T int
set @T = 10455836
--set @T = 421151
select (@T / 1000000) % 100 as hour,
(@T / 10000) % 100 as minute,
(@T / 100) % 100 as second,
(@T % 100) * 10 as millisecond
select dateadd(hour, (@T / 1000000) % 100,
dateadd(minute, (@T / 10000) % 100,
dateadd(second, (@T / 100) % 100,
dateadd(millisecond, (@T % 100) * 10, cast('00:00:00' as time(2))))))
Result:

This is because you have not included web.xml in your web project and trying to build war using maven. To resolve this error, you need to set the failOnMissingWebXml to false in pom.xml file.
For example:
<properties>
<failOnMissingWebXml>false</failOnMissingWebXml>
</properties>
Please see the blog for more details: https://ankurjain26.blogspot.in/2017/05/error-assembling-war-webxml-attribute.html
Since July 2017 you can use cmp.Equal
with cmpopts.IgnoreFields
option.
func TestPerson(t *testing.T) {
type person struct {
ID int
Name string
}
p1 := person{ID: 1, Name: "john doe"}
p2 := person{ID: 2, Name: "john doe"}
println(cmp.Equal(p1, p2))
println(cmp.Equal(p1, p2, cmpopts.IgnoreFields(person{}, "ID")))
// Prints:
// false
// true
}
In my case, replacing all annotations GenerationType.AUTO
by GenerationType.SEQUENCE
solved the issue.
Set them to public. That is, wherever you have the word "protected", change it for the word "public". If you need access control, put it inside, in front of the word 'get' or the word 'set'.
if [ $( ls <file> ) ]; then rm <file>; fi
Also, if you redirect your output with >
instead of >>
it will overwrite the previous file
A simple working solution using vanilla JavaScript:
const valuesToRemove = ["value1", "value2"];
valuesToRemove.forEach(value => {
const mySelect = document.getElementById("my-select");
const valueIndex = Array.from(mySelect.options).findIndex(option => option.value === value);
if (valueIndex > 0) {
mySelect.options.remove(valueIndex);
}
});
For Bootstrap 3 and 4 it's
.collapsing {
-webkit-transition: none;
transition: none;
display: none;
}
Actually there is no mean if an abstract class doesnt have any abstract method . An abstract class is like a father. This father have some properties and behaviors,when you as a child want to be a child of the father, father says the child(you)that must be this way, its our MOTO, and if you don`t want to do, you are not my child.
For sudo you can do this too:
sudo -S <<< "password" command
To avoid all conversions to a list import itertools
and:
>>> for k, g in itertools.groupby(xrange(35), lambda x: x/10):
... list(g)
Produces:
...
0 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
1 [10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
2 [20, 21, 22, 23, 24, 25, 26, 27, 28, 29]
3 [30, 31, 32, 33, 34]
>>>
I checked groupby
and it doesn't convert to list or use len
so I (think) this will delay resolution of each value until it is actually used. Sadly none of the available answers (at this time) seemed to offer this variation.
Obviously if you need to handle each item in turn nest a for loop over g:
for k,g in itertools.groupby(xrange(35), lambda x: x/10):
for i in g:
# do what you need to do with individual items
# now do what you need to do with the whole group
My specific interest in this was the need to consume a generator to submit changes in batches of up to 1000 to the gmail API:
messages = a_generator_which_would_not_be_smart_as_a_list
for idx, batch in groupby(messages, lambda x: x/1000):
batch_request = BatchHttpRequest()
for message in batch:
batch_request.add(self.service.users().messages().modify(userId='me', id=message['id'], body=msg_labels))
http = httplib2.Http()
self.credentials.authorize(http)
batch_request.execute(http=http)
document.getElementById('id1').bgColor = '#00FF00';
seems to work. I don't think .style.backgroundColor
does.
As an alternate method, if you know that there are no spaces in your data, which it seems is the case, you can use split() (with no arguments). This splits on white space and uses a more efficient algorithm than the other version of split. It also strips whitespace from both ends.
line = line.split()
And that's it.

Commands for install APK files like it does in Android Studio you can see below.
1) To push your app:
adb push /pathOfApk/com.my.awesome.apk /data/local/tmp/com.my.awesome
where com.my.awesome
is your package.
2) To install:
adb shell pm install -t -r "/data/local/tmp/com.my.awesome"
Since each registry runs as a container the container ID has an associated log file ID-json.log this log file contains the vars.name=[image] and vars.reference=[tag]. A script can be used to extrapolate and print these. This is perhaps one method to list images pushed to registry V2-2.0.1.
No need to use convert. Simply list it as a quoted date in ISO 8601 format.
Like so:
select * from table1 where somedate between '2000/01/01' and '2099/12/31'
The separator needs to be a /
and it needs to be surrounded by single '
quotes.
Disclaimer: I'm the author of the mentioned package.
I was surprised how the top answers to this question in 2019 still use serialization or reflection.
BinaryFormatter
requires the Serializable
attribute, JsonConverter
requires a parameterless constructor or attributes, neither handle read only fields or interfaces very well and both are 10-30x slower than necessary.
You can instead use Expression Trees or Reflection.Emit to generate cloning code only once, then use that compiled code instead of slow reflection or serialization.
Having come across the problem myself and seeing no satisfactory solution, I decided to create a package that does just that and works with every type and is a almost as fast as custom written code.
You can find the project on GitHub: https://github.com/marcelltoth/ObjectCloner
You can install it from NuGet. Either get the ObjectCloner
package and use it as:
var clone = ObjectCloner.DeepClone(original);
or if you don't mind polluting your object type with extensions get ObjectCloner.Extensions
as well and write:
var clone = original.DeepClone();
A simple benchmark of cloning a class hierarchy showed performance ~3x faster than using Reflection, ~12x faster than Newtonsoft.Json serialization and ~36x faster than the highly suggested BinaryFormatter
.
You can use sed. But if you know perl, that might be easier, and more useful to know in the long run:
perl -n '/(\d+\.\d+\.\d+\.\d+)/ && print "$1\n"' < file
yes the best way to see what is modified is to save in file like that:
git stash show -p stash@{0} > stash.txt
A quick "hack" to tell if two objects are similar, is to use their toString() methods. If you're checking objects A and B, make sure A and B have meaningful toString() methods and check that the strings they return are the same.
This isn't a panacea, but it can be useful sometimes in the right situations.
You can use Open Xml Sdk for this. If you have the code in html with color and formatting. You can use altchunks to add it to the word documents. Refer this post Add HTML String to OpenXML (*.docx) Document Hope this helps!

This is how the Adapter class looks like :
public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewHolder>{
Context context;
ArrayList<RouteDetailsFromFirestore> routeDetailsFromFirestoreArrayList_;
public int lastSelectedPosition=-1;
public MyRecyclerViewAdapter(Context context, ArrayList<RouteDetailsFromFirestore> routeDetailsFromFirestoreArrayList)
{
this.context = context;
this.routeDetailsFromFirestoreArrayList_ = routeDetailsFromFirestoreArrayList;
}
@NonNull
@Override
public MyRecyclerViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i)
{
// LayoutInflater layoutInflater = LayoutInflater.from(mainActivity_.getBaseContext());
LayoutInflater layoutInflater = LayoutInflater.from(viewGroup.getContext());
View view = layoutInflater.inflate(R.layout.route_details, viewGroup, false);
return new MyRecyclerViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull final MyRecyclerViewHolder myRecyclerViewHolder, final int i) {
/* This is the part where the appropriate checking and unchecking of radio button happens appropriately */
myRecyclerViewHolder.mRadioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if(b) {
if (lastSelectedPosition != -1) {
/* Getting the reference to the previously checked radio button and then unchecking it.lastSelectedPosition has the index of the previously selected radioButton */
//RadioButton rb = (RadioButton) ((MainActivity) context).linearLayoutManager.getChildAt(lastSelectedPosition).findViewById(R.id.rbRadioButton);
RadioButton rb = (RadioButton) ((MainActivity) myRecyclerViewHolder.mRadioButton.getContext()).linearLayoutManager.getChildAt(lastSelectedPosition).findViewById(R.id.rbRadioButton);
rb.setChecked(false);
}
lastSelectedPosition = i;
/* Checking the currently selected radio button */
myRecyclerViewHolder.mRadioButton.setChecked(true);
}
}
});
}
@Override
public int getItemCount() {
return routeDetailsFromFirestoreArrayList_.size();
}
} // End of Adapter Class
Inside MainActivity.java we call the ctor of Adapter class like this. The context passed is of MainActivity to the Adapter ctor :
myRecyclerViewAdapter = new MyRecyclerViewAdapter(MainActivity.this, routeDetailsList);

Yes, although it's full of gotchas, since JPA is a bit peculiar. It's very much worth reading the documentation on injecting JPA EntityManager
and EntityManagerFactory
, without explicit Spring dependencies in your code:
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-jpa
This allows you to either inject the EntityManagerFactory
, or else inject a thread-safe, transactional proxy of an EntityManager
directly. The latter makes for simpler code, but means more Spring plumbing is required.
This seems like the easiest (but not most robust) way to me. Simply compute the sum from row 6 to the maximum allowed row number, as specified by Excel. According to this site, the maximum is currently 1048576, so the following should work for you:
=sum(c6:c1048576)
For more robust solutions, see the other answers.
if you want to do it with pure HTML solution ,you can delete the border in the table if you want...or you can add align="center" attribute to your img tag like this:
<img align="center" width="100%" height="100%" src="http://dummyimage.com/68x68/000/fff" />
see the fiddle : http://jsfiddle.net/Lk2Rh/27/
but still it better to handling this with CSS, i suggest you that.
Assuming you have a properties file on your classpath that contains
api.orders.pingFrequency=4
I tried inside a @Controller
@Controller
public class MyController {
@Value("${api.orders.pingFrequency}")
private Integer pingFrequency;
...
}
With my servlet context containing :
<context:property-placeholder location="classpath:myprops.properties" />
It worked perfectly.
So either your property is not an integer type, you don't have the property placeholder configured correctly, or you are using the wrong property key.
I tried running with an invalid property value, 4123;
. The exception I got is
java.lang.NumberFormatException: For input string: "4123;"
which makes me think the value of your property is
api.orders.pingFrequency=(java.lang.Integer)${api.orders.pingFrequency}

You should just use something like:
YourModel.update_all(
ActiveRecord::Base.send(:sanitize_sql_for_assignment, {:value => "'wow'"})
)
That would do the trick. Using the ActiveRecord::Base#send method to invoke the sanitize_sql_for_assignment makes the Ruby (at least the 1.8.7 version) skip the fact that the sanitize_sql_for_assignment is actually a protected method.
Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.
Try using this command to allow a port
sudo ufw allow 1701
To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:
nc -l 1701
Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.
I just wanted to give my two cents.
This is according to @Powerlord 's answer.
Puts "null" instead of null strings.
private static Dictionary<string, string> map = new Dictionary<string, string>();
public static void put(string key, string value)
{
if (value == null) value = "null";
map[key] = value;
}
public static string get(string key, string defaultValue)
{
try
{
return map[key];
}
catch (KeyNotFoundException e)
{
return defaultValue;
}
}
public static string get(string key)
{
return get(key, "null");
}
well, easiest way would be something like:
var address = theEncodedString.split(/~/)
var name = address[0], street = address[1]
I had similar issue with selenium: I downgraded my selenium using NuGet and got the same error message. My solution was to remove the newer version lines from the app.config file.
For UTF-8 textual information, you should use utf8_general_ci
because...
utf8_bin
: compare strings by the
binary value of each character in
the string
utf8_general_ci
: compare strings
using general language rules and
using case-insensitive comparisons
a.k.a. it will should making searching and indexing the data faster/more efficient/more useful.
string FileExtn = System.IO.Path.GetExtension(fpdDocument.PostedFile.FileName);
The above method works fine with the firefox and IE , i am able to view all types of files like zip,txt,xls,xlsx,doc,docx,jpg,png
but when i try to find the extension of file from googlechrome , i failed.
i have alreay 2 situations where directives and services/factories didnt play well.
the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).
in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.
i even tried to make a directive with a controller and an isolated-scope
only when i moved everything to a controller and it worked like magic.
example about this here Initialising jQuery plugin (RoyalSlider) in Angular JS
Try this
SELECT DATEDIFF(DAY, DATEADD(day, -1, '2013-03-13 00:00:00.000'), GETDATE())
OR
SELECT DATEDIFF(DAY, DATEADD(day, -1, @CreatedDate), GETDATE())
A few observations:
The recommended pattern for a singleton object would be as follows. dispatch_once makes sure the class is initialised once in a thread-safe way, and the static variable isn't visible outside. And it's standard GCD, so no need to know about low level details of Objective-C.
+ (KeyboardStateListener *)sharedInstance
{
static KeyboardStateListener* shared;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
shared = [[KeyboardStateListener alloc] init];
// Other initialisations
});
return shared;
}
Usually you don't want to know just whether the keyboard is visible or not, but how big it is. Keyboards don't all have the same size. iPhone keyboards are smaller than iPad keyboards. So you'd want another property @property (readonly, nonatomic) CGRect keyboardRect;
which is set in the noticeShowKeyboard: method like this:
NSValue* value = notification.userInfo [UIKeyboardFrameEndUserInfoKey];
_keyboardRect = value.CGRectValue;
Important to notice that the rectangle is in UIWindow coordinates and doesn't respect screen rotation. So the caller would convert that rectangle by calling
KeyboardStateListener* listener = [KeyboardStateListener sharedInstance];
CGRect windowRect = listener.keyboardRect;
CGRect viewRect = [myView convertRect:windowRect fromView:self.window];
If the user rotates the screen while the keyboard is visible, the app will be told that the keyboard is hidden, then shown again. When it is shown, other views are most likely not rotated yet. So if you observe keyboard hide/show events yourself, convert the coordinates when you actually need them, not in the notification.
If the user splits or undocks the keyboard, or uses a hardware keyboard, the notifications will always show the keyboard as hidden. Undocking or merging the keyboard will send a "keyboard shown" notification.
The listener must be initialised while the keyboard is hidden, otherwise the first notification will be missed, and it will be assumed that the keyboard is hidden when it's not.
So it is quite important to know what you actually want. This code is useful to move things out of the way of the keyboard (with a split or undocked keyboard, that's the responsibility of the user). It doesn't tell you whether the user can see a keyboard on the screen (in case of a split keyboard). It doesn't tell you whether the user can type (for example when there is a hardware keyboard). Looking at other windows doesn't work if the app creates other windows itself.
This isn't very well documented, but we can trigger any kinds of events very simply.
This example will trigger 50 double click on the button:
let theclick = new Event("dblclick")
for (let i = 0;i < 50;i++){
action.dispatchEvent(theclick)
}
_x000D_
<button id="action" ondblclick="out.innerHTML+='Wtf '">TEST</button>
<div id="out"></div>
_x000D_
The Event interface represents an event which takes place in the DOM.
An event can be triggered by the user action e.g. clicking the mouse button or tapping keyboard, or generated by APIs to represent the progress of an asynchronous task. It can also be triggered programmatically, such as by calling the HTMLElement.click() method of an element, or by defining the event, then sending it to a specified target using EventTarget.dispatchEvent().

Agreed completely that this is a path issue but fwiw, I had this same error. It was due to the mistake of using a relative path for my Python executable when setting up my virtual environment. I had done this:
virtualenv -p ~/python_runtimes/2.7.3/bin/python venv2.7.3 --distribute
Instead I had to give the full path to the Python executable.

I'm not familiar with postgresql, but in SQL Server or Oracle, using a subquery would work like below (in Oracle, the SELECT 0
would be SELECT 0 FROM DUAL
)
SELECT SUM(sub.value)
FROM
(
SELECT SUM(columnA) as value FROM my_table
WHERE columnB = 1
UNION
SELECT 0 as value
) sub
Maybe this would work for postgresql too?
Pure Javascript, without regular expression:
var result = replaceSpacesText.split(" ").join("");
WITH CTE AS (
SELECT
rownum = ROW_NUMBER() OVER (ORDER BY columns_to_order_by),
value
FROM table
)
SELECT
curr.value - prev.value
FROM CTE cur
INNER JOIN CTE prev on prev.rownum = cur.rownum - 1
To clone a repository and place it in a specified directory use "git clone [url] [directory]". For example
git clone https://github.com/ryanb/railscasts-episodes.git Rails
will create a directory named "Rails" and place it in the new directory. Click here for more information.
Because that's not what strip()
does. It removes leading and trailing characters that are present in the argument, but not those characters in the middle of the string.
You could do:
name= name.replace('(', '').replace(')', '').replace ...
or:
name= ''.join(c for c in name if c not in '(){}<>')
or maybe use a regex:
import re
name= re.sub('[(){}<>]', '', name)

For the original question based on Bootstrap 3, the solution was to use push-pull.
In Bootstrap 4 it's now possible to change the order, even when the columns are full-width stacked vertically, thanks to Bootstrap 4 flexbox. OFC, the push pull method will still work, but now there are other ways to change column order in Bootstrap 4, making it possible to re-order full-width columns.
Method 1 - Use flex-column-reverse
for xs
screens:
<div class="row flex-column-reverse flex-md-row">
<div class="col-md-3">
sidebar
</div>
<div class="col-md-9">
main
</div>
</div>
Method 2 - Use order-first
for xs
screens:
<div class="row">
<div class="col-md-3">
sidebar
</div>
<div class="col-md-9 order-first order-md-last">
main
</div>
</div>

Bootstrap 4.1: https://www.codeply.com/go/e0v77yGtcr
Original 3.x Answer
For the original question based on Bootstrap 3, the solution was to use push-pull for the larger widths, and then the columns will show is their natural order on smaller (xs) widths. (A-B reverse to B-A).
<div class="container">
<div class="row">
<div class="col-md-9 col-md-push-3">
main
</div>
<div class="col-md-3 col-md-pull-9">
sidebar
</div>
</div>
</div>
Bootstrap 3: http://www.codeply.com/go/wgzJXs3gel
@emre stated, "You cannot change the order of columns in smaller screens but you can do that in large screens". However, this should be clarified to state: "You cannot change the order of full-width "stacked" columns.." in Bootstrap 3.
This can be simply done like this.
created() {
var scripts = [
"https://cloudfront.net/js/jquery-3.4.1.min.js",
"js/local.js"
];
scripts.forEach(script => {
let tag = document.createElement("script");
tag.setAttribute("src", script);
document.head.appendChild(tag);
});
}
It has nothing to do with append
. tuple(3, 4)
all by itself raises that error.
The reason is that, as the error message says, tuple
expects an iterable argument. You can make a tuple of the contents of a single object by passing that single object to tuple. You can't make a tuple of two things by passing them as separate arguments.
Just do (3, 4)
to make a tuple, as in your first example. There's no reason not to use that simple syntax for writing a tuple.
You can also try this:
constructor(props) {
super(props);
this.state = {height: props.height, width:props.width};
}
componentWillMount(){
console.log("WINDOW : ",window);
this.setState({height: window.innerHeight + 'px',width:window.innerWidth+'px'});
}
render() {
console.log("VIEW : ",this.state);
}
An equivalent statement would be
select * from [TableName] limit 5

Possible options to exclude files/directories from backup using tar:
Exclude files using multiple patterns
tar -czf backup.tar.gz --exclude=PATTERN1 --exclude=PATTERN2 ... /path/to/backup
Exclude files using an exclude file filled with a list of patterns
tar -czf backup.tar.gz -X /path/to/exclude.txt /path/to/backup
Exclude files using tags by placing a tag file in any directory that should be skipped
tar -czf backup.tar.gz --exclude-tag-all=exclude.tag /path/to/backup
You should use val
instead of value
.
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$('input[name="testing"]').val('Work!');
});
</script>

You can do it this way on Java.
public List<Double> convertGpsToECEF(double lat, double longi, float alt) {
double a=6378.1;
double b=6356.8;
double N;
double e= 1-(Math.pow(b, 2)/Math.pow(a, 2));
N= a/(Math.sqrt(1.0-(e*Math.pow(Math.sin(Math.toRadians(lat)), 2))));
double cosLatRad=Math.cos(Math.toRadians(lat));
double cosLongiRad=Math.cos(Math.toRadians(longi));
double sinLatRad=Math.sin(Math.toRadians(lat));
double sinLongiRad=Math.sin(Math.toRadians(longi));
double x =(N+0.001*alt)*cosLatRad*cosLongiRad;
double y =(N+0.001*alt)*cosLatRad*sinLongiRad;
double z =((Math.pow(b, 2)/Math.pow(a, 2))*N+0.001*alt)*sinLatRad;
List<Double> ecef= new ArrayList<>();
ecef.add(x);
ecef.add(y);
ecef.add(z);
return ecef;
}
When inserting the generated ID is saved into the instance of the object being saved (see below):
protected void btnInsertProductCategory_Click(object sender, EventArgs e)
{
ProductCategory productCategory = new ProductCategory();
productCategory.Name = “Sample Category”;
productCategory.ModifiedDate = DateTime.Now;
productCategory.rowguid = Guid.NewGuid();
int id = InsertProductCategory(productCategory);
lblResult.Text = id.ToString();
}
//Insert a new product category and return the generated ID (identity value)
private int InsertProductCategory(ProductCategory productCategory)
{
ctx.ProductCategories.InsertOnSubmit(productCategory);
ctx.SubmitChanges();
return productCategory.ProductCategoryID;
}

The method argument specifies the parameter of the smooth statistic. You can see stat_smooth
for the list of all possible arguments to the method argument.
The built-in process module has a method memoryUsage
that offers insight in the memory usage of the current Node.js process. Here is an example from in Node v0.12.2 on a 64-bit system:
$ node --expose-gc
> process.memoryUsage(); // Initial usage
{ rss: 19853312, heapTotal: 9751808, heapUsed: 4535648 }
> gc(); // Force a GC for the baseline.
undefined
> process.memoryUsage(); // Baseline memory usage.
{ rss: 22269952, heapTotal: 11803648, heapUsed: 4530208 }
> var a = new Array(1e7); // Allocate memory for 10m items in an array
undefined
> process.memoryUsage(); // Memory after allocating so many items
{ rss: 102535168, heapTotal: 91823104, heapUsed: 85246576 }
> a = null; // Allow the array to be garbage-collected
null
> gc(); // Force GC (requires node --expose-gc)
undefined
> process.memoryUsage(); // Memory usage after GC
{ rss: 23293952, heapTotal: 11803648, heapUsed: 4528072 }
> process.memoryUsage(); // Memory usage after idling
{ rss: 23293952, heapTotal: 11803648, heapUsed: 4753376 }
In this simple example, you can see that allocating an array of 10M elements consumers approximately 80MB (take a look at heapUsed
).
If you look at V8's source code (Array::New
, Heap::AllocateRawFixedArray
, FixedArray::SizeFor
), then you'll see that the memory used by an array is a fixed value plus the length multiplied by the size of a pointer. The latter is 8 bytes on a 64-bit system, which confirms that observed memory difference of 8 x 10 = 80MB makes sense.

You can also create a custom extension of the EditText that knows to open the soft keyboard when it receives focus. That's what I've ended up doing. Here's what worked for me:
public class WellBehavedEditText extends EditText {
private InputMethodManager inputMethodManager;
private boolean showKeyboard = false;
public WellBehavedEditText(Context context) {
super(context);
this.initializeWellBehavedEditText(context);
}
public WellBehavedEditText(Context context, AttributeSet attributes) {
super(context, attributes);
this.initializeWellBehavedEditText(context);
}
public WellBehavedEditText(Context context, AttributeSet attributes, int defStyleAttr) {
super(context, attributes, defStyleAttr);
this.initializeWellBehavedEditText(context);
}
public WellBehavedEditText(Context context, AttributeSet attributes, int defStyleAttr, int defStyleRes) {
super(context, attributes, defStyleAttr, defStyleRes);
this.initializeWellBehavedEditText(context);
}
private void initializeWellBehavedEditText(Context context) {
this.inputMethodManager = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
final WellBehavedEditText editText = this;
this.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
if(showKeyboard) {
showKeyboard = !(inputMethodManager.showSoftInput(editText, InputMethodManager.SHOW_FORCED));
}
}
});
}
@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(!focused) this.showKeyboard = false;
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public boolean requestFocus(int direction, Rect previouslyFocusedRect) {
boolean result = super.requestFocus(direction, previouslyFocusedRect);
this.showKeyboard = true;
final WellBehavedEditText self = this;
this.post(new Runnable() {
@Override
public void run() {
showKeyboard = !(inputMethodManager.showSoftInput(self, InputMethodManager.SHOW_FORCED));
}
});
return result;
}
}

If you want to refresh the table without adding new data then use this:
First, create the API variable of your table like this:
var myTableApi = $('#mytable').DataTable(); // D must be Capital in this.
And then use refresh code wherever you want:
myTableApi.search(jQuery('input[type="search"]').val()).draw() ;
It will search data table with current search value (even if it's blank) and refresh data,, this work even if Datatable has server-side processing enabled.
String and StringBuilder are actually both immutable, the StringBuilder has built in buffers which allow its size to be managed more efficiently. When the StringBuilder needs to resize is when it is re-allocated on the heap. By default it is sized to 16 characters, you can set this in the constructor.
eg.
StringBuilder sb = new StringBuilder(50);
Use the various urlparse
functions to tear apart the existing URL, urllib.urlencode()
on the combined dictionary, then urlparse.urlunparse()
to put it all back together again.
Or just take the result of urllib.urlencode()
and concatenate it to the URL appropriately.

There are MYSQL functions you can use. Like this one that resolves the user:
SELECT USER();
This will return something like root@localhost
so you get the host and the user.
To get the current database run this statement:
SELECT DATABASE();
Other useful functions can be found here: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html
Though the question appears to be demanding plotting a histogram using matplotlib.hist()
function, it can arguably be not done using the same as the latter part of the question demands to use the given probabilities as the y-values of bars and given names(strings) as the x-values.
I'm assuming a sample list of names corresponding to given probabilities to draw the plot. A simple bar plot serves the purpose here for the given problem. The following code can be used:
import matplotlib.pyplot as plt
probability = [0.3602150537634409, 0.42028985507246375,
0.373117033603708, 0.36813186813186816, 0.32517482517482516,
0.4175257731958763, 0.41025641025641024, 0.39408866995073893,
0.4143222506393862, 0.34, 0.391025641025641, 0.3130841121495327,
0.35398230088495575]
names = ['name1', 'name2', 'name3', 'name4', 'name5', 'name6', 'name7', 'name8', 'name9',
'name10', 'name11', 'name12', 'name13'] #sample names
plt.bar(names, probability)
plt.xticks(names)
plt.yticks(probability) #This may be included or excluded as per need
plt.xlabel('Names')
plt.ylabel('Probability')
I think configuring WINHTTP will also work.
Many programs including Windows Updates are having problems behind proxy. By setting up WINHTTP will always fix this kind of problems
Just one line:
idx = max(range(len(a)), key = lambda i: a[i])
Something like this should do the trick
function array_max_key($array) {
$max_key = -1;
$max_val = -1;
foreach ($array as $key => $value) {
if ($value > $max_val) {
$max_key = $key;
$max_val = $value;
}
}
return $max_key;
}
First of all store $date=$_POST['your date field name'];
insert into **Your_Table Name** values('$date',**other fields**);
You must contain date in single cote (' ')
I hope it is helps.
While a good answer has been given (using Process.Start
), it is safer to encapsulate it in a function that checks that the passed string is indeed a URI, to avoid accidentally starting random processes on the machine.
public static bool IsValidUri(string uri)
{
if (!Uri.IsWellFormedUriString(uri, UriKind.Absolute))
return false;
Uri tmp;
if (!Uri.TryCreate(uri, UriKind.Absolute, out tmp))
return false;
return tmp.Scheme == Uri.UriSchemeHttp || tmp.Scheme == Uri.UriSchemeHttps;
}
public static bool OpenUri(string uri)
{
if (!IsValidUri(uri))
return false;
System.Diagnostics.Process.Start(uri);
return true;
}
The href value inside the base tag will become your reference point for all your relative paths and thus override your current directory path value otherwise - the '~' is the root of your site
<head>
<base href="~/" />
</head>
you can't initialise var with null, var needs to be initialised as a type otherwise it cannot be inferred, if you think you need to do this maybe you can post the code it is probable that there is another way to do what you are attempting.
As alternative you always can try a simpler workaround, using another icon, for example:
<button type="button" style="background:none;border:none">
<span class="fa fa-reorder"></span>
</button>
ref: https://www.w3schools.com/icons/fontawesome_icons_webapp.asp
<button type="button" style="background:none;border:none">
<span class="glyphicon glyphicon-align-justify"></span>
</button>

So you gain total control over their color and size:
button span {
/*overwriting*/
color: white;
font-size: 25px;
}
(the button's style applied is just for a quick test):
As an expansion/enhancement to the brilliant addition made by @rodowi above regarding being able to overwrite a row:
process.stdout.write("Downloading " + data.length + " bytes\r");
Should you not want the terminal cursor to be located at the first character, as I saw in my code, the consider doing the following:
let dots = ''
process.stdout.write(`Loading `)
let tmrID = setInterval(() => {
dots += '.'
process.stdout.write(`\rLoading ${dots}`)
}, 1000)
setTimeout(() => {
clearInterval(tmrID)
console.log(`\rLoaded in [3500 ms]`)
}, 3500)
By placing the \r
in front of the next print statement the cursor is reset just before the replacing string overwrites the previous.
you need to place the opening brace after main
, not before it
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void)
{
Use git checkout
instead of git stash apply
:
$ git checkout stash -- .
$ git commit
This will restore all the files in the current directory to their stashed version.
If there are changes to other files in the working directory that should be kept, here is a less heavy-handed alternative:
$ git merge --squash --strategy-option=theirs stash
If there are changes in the index, or the merge will touch files with local changes, git will refuse to merge. Individual files can be checked out from the stash using
$ git checkout stash -- <paths...>
or interactively with
$ git checkout -p stash
The +
operation adds the array elements to the original array. The array.append
operation inserts the array (or any object) into the end of the original array, which results in a reference to self in that spot (hence the infinite recursion).
The difference here is that the + operation acts specific when you add an array (it's overloaded like others, see this chapter on sequences) by concatenating the element. The append-method however does literally what you ask: append the object on the right-hand side that you give it (the array or any other object), instead of taking its elements.
Use extend()
if you want to use a function that acts similar to the + operator (as others have shown here as well). It's not wise to do the opposite: to try to mimic append with the + operator for lists (see my earlier link on why).
For fun, a little history: the birth of the array module in Python in February 1993. it might surprise you, but arrays were added way after sequences and lists came into existence.
Inline code takes higher precedence than the other ones. To call your other function func () call it from the f1 ().
Inside your function, add a line,
function fun () {
// Your code here
}
function f1()
{
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.
fun ();
}
Rewriting your whole code,
<!DOCTYPE html>
<html>
<head>
<script>
function fun()
{
alert("hello");
//validation code to see State field is mandatory.
}
function f1()
{
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.
fun ();
}
</script>
</head>
<body>
<form name="form1" id="form1" method="post">
State: <select id="state ID">
<option></option>
<option value="ap">ap</option>
<option value="bp">bp</option>
</select>
</form>
<table><tr><td id="Save" onclick="f1()">click</td></tr></table>
</body>
</html>
If you aren't comfortable with using negative margins, check this out.
div {
position: fixed;
left: 50%;
bottom: 20px;
transform: translate(-50%, -50%);
margin: 0 auto;
}
<div>
Your Text
</div>
Especially useful when you don't know the width of the div.
align="center"
has no effect.
Since you have position:absolute
, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.
#manipulate {
position:absolute;
width:300px;
height:300px;
background:#063;
bottom:0px;
right:25%;
left:50%;
margin-left:-150px;
}
TL;DR: Yes, the only Swift language implementation is slow, right now. If you need fast, numeric (and other types of code, presumably) code, just go with another one. In the future, you should re-evaluate your choice. It might be good enough for most application code that is written at a higher level, though.
From what I'm seeing in SIL and LLVM IR, it seems like they need a bunch of optimizations for removing retains and releases, which might be implemented in Clang (for Objective-C), but they haven't ported them yet. That's the theory I'm going with (for now… I still need to confirm that Clang does something about it), since a profiler run on the last test-case of this question yields this “pretty” result:
As was said by many others, -Ofast
is totally unsafe and changes language semantics. For me, it's at the “If you're going to use that, just use another language” stage. I'll re-evaluate that choice later, if it changes.
-O3
gets us a bunch of swift_retain
and swift_release
calls that, honestly, don't look like they should be there for this example. The optimizer should have elided (most of) them AFAICT, since it knows most of the information about the array, and knows that it has (at least) a strong reference to it.
It shouldn't emit more retains when it's not even calling functions which might release the objects. I don't think an array constructor can return an array which is smaller than what was asked for, which means that a lot of checks that were emitted are useless. It also knows that the integer will never be above 10k, so the overflow checks can be optimized (not because of -Ofast
weirdness, but because of the semantics of the language (nothing else is changing that var nor can access it, and adding up to 10k is safe for the type Int
).
The compiler might not be able to unbox the array or the array elements, though, since they're getting passed to sort()
, which is an external function and has to get the arguments it's expecting. This will make us have to use the Int
values indirectly, which would make it go a bit slower. This could change if the sort()
generic function (not in the multi-method way) was available to the compiler and got inlined.
This is a very new (publicly) language, and it is going through what I assume are lots of changes, since there are people (heavily) involved with the Swift language asking for feedback and they all say the language isn't finished and will change.
Code used:
import Cocoa
let swift_start = NSDate.timeIntervalSinceReferenceDate();
let n: Int = 10000
let x = Int[](count: n, repeatedValue: 1)
for i in 0..n {
for j in 0..n {
let tmp: Int = x[j]
x[i] = tmp
}
}
let y: Int[] = sort(x)
let swift_stop = NSDate.timeIntervalSinceReferenceDate();
println("\(swift_stop - swift_start)s")
P.S: I'm not an expert on Objective-C nor all the facilities from Cocoa, Objective-C, or the Swift runtimes. I might also be assuming some things that I didn't write.
I had a similar problem with lazy loading via the hibernate proxy object. Got around it by annotating the class having lazyloaded private properties with:
@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
I assume you can add the properties on your proxy object that breaks the JSON serialization to that annotation.
void myfunc(void)
{
char* text = "Hello World";
char aLetter = 'C';
printf("%s\n", text);
printf("%c\n", aLetter);
}
grep
is made for this.
Use grep myword *
And check man grep
.
I've written just this to execute compiling and run the file after, plus fileinputname = fileoutputname on windowsmashines, if your compilerpath is registred in the windows PATH-var:
NPP_SAVE
cd "$(CURRENT_DIRECTORY)"
set LEN~ strrfind $(FILE_NAME) .
set EXENAME ~ substr 0 $(LEN) $(FILE_NAME)
set $(EXENAME) = $(EXENAME).exe
c++.exe "$(FILE_NAME)" -o "$(EXENAME)"
"$(EXENAME)"
should work for any compiler if you change c++.exe to what you want
Well, I figured it out myself, right after posting, which is the most embarassing way. :)
It seems every member of a StackPanel will simply fill its minimum requested size.
In the DockPanel, I had docked things in the wrong order. If the TextBox or ListBox is the only docked item without an alignment, or if they are the last added, they WILL fill the remaining space as wanted.
I would love to see a more elegant method of handling this, but it will do.
Updated for Bootstrap 3.3.4:
This will allow you to have different display text and data value for each element. It will also persist the caret on selection.
JS:
$(".dropdown-menu li a").click(function(){
$(this).parents(".dropdown").find('.btn').html($(this).text() + ' <span class="caret"></span>');
$(this).parents(".dropdown").find('.btn').val($(this).data('value'));
});
HTML:
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li><a href="#" data-value="action">Action</a></li>
<li><a href="#" data-value="another action">Another action</a></li>
<li><a href="#" data-value="something else here">Something else here</a></li>
<li><a href="#" data-value="separated link">Separated link</a></li>

This is swift 5 compatible answer. If you want to use one of the built-in colours then you can simply use
button.setTitleColor(.red, for: .normal)
If you want some custom colours, then create an extension for a UIColor as below first.
import UIKit
extension UIColor {
static var themeMoreButton = UIColor.init(red: 53/255, green: 150/255, blue: 36/255, alpha: 1)
}
Then use it for your button as below.
button.setTitleColor(UIColor.themeMoreButton, for: .normal)
Tip: You can use this method to store custom colours from rgba colour code and reuse it throughout your application.
I've been bitten before by (someone else's) "clever" code that tries to modify a list while iterating over it. I resolved that I would never do it under any circumstance.
You can use the slice operator mylist[::3]
to skip across to every third item in your list.
mylist = [i for i in range(100)]
for i in mylist[::3]:
print(i)
Other points about my example relate to new syntax in python 3.0.
Python 3.0 range() now behaves like xrange() used to behave, except it works with values of arbitrary size. The latter no longer exists.
To connect use ssh like so:
ssh -i keyname.pem [email protected]
Where keyname.pem
is the name of your private key, username
is the correct username for your os distribution, and xxx.xx.xxx.xx
is the public ip address.
When it times out or fails, check the following:
Make sure to have an inbound rule for tcp port 22 and either all ips or your ip. You can find the security group through the ec2 menu, in the instance options.
For a new subnet in a vpc, you need to change to a routing table that points 0.0.0.0/0 to internet gateway target. When you create the subnet in your vpc, by default it assigns the default routing table, which probably does not accept incoming traffic from the internet. You can edit the routing table options in the vpc menu and then subnets.
For an instance in a vpc, you need to assign a public elastic ip address, and associate it with the instance. The private ip address can't be accessed from the outside. You can get an elastic ip in the ec2 menu (not instance menu).
Make sure you're using the correct username. It should be one of ec2-user
or root
or ubuntu
. Try them all if necessary.
Make sure you're using the correct private key (the one you download or choose when launching the instance). Seems obvious, but copy paste got me twice.
I'll mention the more obvious way of dealing with duplicates in lists. In terms of complexity, dictionaries are the way to go because each lookup is O(1). You can be more clever if you're only interested in duplicates...
my_list = [1,1,2,3,4,5,5]
my_dict = {}
for (ind,elem) in enumerate(my_list):
if elem in my_dict:
my_dict[elem].append(ind)
else:
my_dict.update({elem:[ind]})
for key,value in my_dict.iteritems():
if len(value) > 1:
print "key(%s) has indices (%s)" %(key,value)
which prints the following:
key(1) has indices ([0, 1])
key(5) has indices ([5, 6])
You can use it without doing anything special. If you have a local image called blah
you can do FROM blah
. If you do FROM blah
in your Dockerfile, but don't have a local image called blah
, then Docker will try to pull it from the registry.
In other words, if a Dockerfile does FROM ubuntu
, but you have a local image called ubuntu
different from the official one, your image will override it.
The simplest way to handle this case is by using getattr()
. You can adapt this example to your needs:
from bs4 import BeautifulSoup
source_html = """
<span class="ratingsDisplay">
<a class="ratingNumber" href="https://www.youtube.com/watch?v=oHg5SJYRHA0" target="_blank" rel="noopener">
<span class="ratingsContent">3.7</span>
</a>
</span>
"""
soup = BeautifulSoup(source_html, "lxml")
my_ratings = getattr(soup.find('span', {"class": "ratingsContent"}), "text", None)
print(my_ratings)
This will find the text element,"3.7"
, within the tag object <span class="ratingsContent">3.7</span>
when it exists, however, default to NoneType
when it does not.
getattr(object, name[, default])
Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example, getattr(x, 'foobar') is equivalent to x.foobar. If the named attribute does not exist, default is returned if provided, otherwise, AttributeError is raised.
This is solution with FormGroup
inside supports ( like here )
Tested on: Angular 4.3.6
get-form-validation-errors.ts
import { AbstractControl, FormGroup, ValidationErrors } from '@angular/forms';
export interface AllValidationErrors {
control_name: string;
error_name: string;
error_value: any;
}
export interface FormGroupControls {
[key: string]: AbstractControl;
}
export function getFormValidationErrors(controls: FormGroupControls): AllValidationErrors[] {
let errors: AllValidationErrors[] = [];
Object.keys(controls).forEach(key => {
const control = controls[ key ];
if (control instanceof FormGroup) {
errors = errors.concat(getFormValidationErrors(control.controls));
}
const controlErrors: ValidationErrors = controls[ key ].errors;
if (controlErrors !== null) {
Object.keys(controlErrors).forEach(keyError => {
errors.push({
control_name: key,
error_name: keyError,
error_value: controlErrors[ keyError ]
});
});
}
});
return errors;
}
Using example:
if (!this.formValid()) {
const error: AllValidationErrors = getFormValidationErrors(this.regForm.controls).shift();
if (error) {
let text;
switch (error.error_name) {
case 'required': text = `${error.control_name} is required!`; break;
case 'pattern': text = `${error.control_name} has wrong pattern!`; break;
case 'email': text = `${error.control_name} has wrong email format!`; break;
case 'minlength': text = `${error.control_name} has wrong length! Required length: ${error.error_value.requiredLength}`; break;
case 'areEqual': text = `${error.control_name} must be equal!`; break;
default: text = `${error.control_name}: ${error.error_name}: ${error.error_value}`;
}
this.error = text;
}
return;
}
"I do not know if it is out of ignorance, but I do not like that kind of programming, as it is using exceptions to perform flow control."
In the Python world, using exceptions for flow control is common and normal.
Even the Python core developers use exceptions for flow-control and that style is heavily baked into the language (i.e. the iterator protocol uses StopIteration to signal loop termination).
In addition, the try-except-style is used to prevent the race-conditions inherent in some of the "look-before-you-leap" constructs. For example, testing os.path.exists results in information that may be out-of-date by the time you use it. Likewise, Queue.full returns information that may be stale. The try-except-else style will produce more reliable code in these cases.
"It my understanding that exceptions are not errors, they should only be used for exceptional conditions"
In some other languages, that rule reflects their cultural norms as reflected in their libraries. The "rule" is also based in-part on performance considerations for those languages.
The Python cultural norm is somewhat different. In many cases, you must use exceptions for control-flow. Also, the use of exceptions in Python does not slow the surrounding code and calling code as it does in some compiled languages (i.e. CPython already implements code for exception checking at every step, regardless of whether you actually use exceptions or not).
In other words, your understanding that "exceptions are for the exceptional" is a rule that makes sense in some other languages, but not for Python.
"However, if it is included in the language itself, there must be a good reason for it, isn't it?"
Besides helping to avoid race-conditions, exceptions are also very useful for pulling error-handling outside loops. This is a necessary optimization in interpreted languages which do not tend to have automatic loop invariant code motion.
Also, exceptions can simplify code quite a bit in common situations where the ability to handle an issue is far removed from where the issue arose. For example, it is common to have top level user-interface code calling code for business logic which in turn calls low-level routines. Situations arising in the low-level routines (such as duplicate records for unique keys in database accesses) can only be handled in top-level code (such as asking the user for a new key that doesn't conflict with existing keys). The use of exceptions for this kind of control-flow allows the mid-level routines to completely ignore the issue and be nicely decoupled from that aspect of flow-control.
There is a nice blog post on the indispensibility of exceptions here.
Also, see this Stack Overflow answer: Are exceptions really for exceptional errors?
"What is the reason for the try-except-else to exist?"
The else-clause itself is interesting. It runs when there is no exception but before the finally-clause. That is its primary purpose.
Without the else-clause, the only option to run additional code before finalization would be the clumsy practice of adding the code to the try-clause. That is clumsy because it risks raising exceptions in code that wasn't intended to be protected by the try-block.
The use-case of running additional unprotected code prior to finalization doesn't arise very often. So, don't expect to see many examples in published code. It is somewhat rare.
Another use-case for the else-clause is to perform actions that must occur when no exception occurs and that do not occur when exceptions are handled. For example:
recip = float('Inf')
try:
recip = 1 / f(x)
except ZeroDivisionError:
logging.info('Infinite result')
else:
logging.info('Finite result')
Another example occurs in unittest runners:
try:
tests_run += 1
run_testcase(case)
except Exception:
tests_failed += 1
logging.exception('Failing test case: %r', case)
print('F', end='')
else:
logging.info('Successful test case: %r', case)
print('.', end='')
Lastly, the most common use of an else-clause in a try-block is for a bit of beautification (aligning the exceptional outcomes and non-exceptional outcomes at the same level of indentation). This use is always optional and isn't strictly necessary.
iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.
Use scp priv_key.pem source user@host:target
if you need to connect using a private key.
or if using pscp then use pscp -i priv_key.ppk source user@host:target
For a concise way to retain the folder hierarchy under the parent directory to be archived:
import glob
import zipfile
with zipfile.ZipFile(fp_zip, "w", zipfile.ZIP_DEFLATED) as zipf:
for fp in glob(os.path.join(parent, "**/*")):
base = os.path.commonpath([parent, fp])
zipf.write(fp, arcname=fp.replace(base, ""))
If you want, you could change this to use pathlib
for file globbing.
If you are providing mappings like this:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new ClassificationMap());
modelBuilder.Configurations.Add(new CompanyMap());
modelBuilder.Configurations.Add(new GroupMap());
....
}
Remember to add the map for BaseCs.
You won't get a compile error if it is missing. But you will get a runtime error when you use the entity.
You can use JPGraph and Graphpite
#include <string.h>
char *token;
char line[] = "SEVERAL WORDS";
char *search = " ";
// Token will point to "SEVERAL".
token = strtok(line, search);
// Token will point to "WORDS".
token = strtok(NULL, search);
Note that on some operating systems, strtok
man page mentions:
This interface is obsoleted by strsep(3).
An example with strsep
is shown below:
char* token;
char* string;
char* tofree;
string = strdup("abc,def,ghi");
if (string != NULL) {
tofree = string;
while ((token = strsep(&string, ",")) != NULL)
{
printf("%s\n", token);
}
free(tofree);
}
If you work with visual studio designer, you will probably have defined fields for each columns in the YourForm.Designer.cs
file e.g.:
private System.Windows.Forms.DataGridViewCheckBoxColumn dataGridViewCheckBoxColumn1;
private System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn2;
If you give them useful names, you can set the HeaderText
easily:
usefulNameForDataGridViewTextBoxColumn.HeaderText = "Useful Header Text";
I found the answer I was looking for. The thing to use here is the construct of
\left \middle \right
For example, in this case, two possible solutions are:
$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $
Or, in case the brackets are not necessary:
$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

These steps worked for me to increase the space on my windows VM:
Resize the VDI:
VBoxManage modifyhd Cloned.vdi --resize 45000
Run your cloned VM, go to Disk Management and extend the volume.
All of the answers above are correct; attr_reader
and attr_writer
are more convenient to write than manually typing the methods they are shorthands for. Apart from that they offer much better performance than writing the method definition yourself. For more info see slide 152 onwards from this talk (PDF) by Aaron Patterson.
The accepted answer has it spot on, but if you might want to specify which class label should be assigned to a specific color or label you could do the following. I did a little label gymnastics with the colorbar, but making the plot itself reduces to a nice one-liner. This works great for plotting the results from classifications done with sklearn. Each label matches a (x,y) coordinate.
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
x = [4,8,12,16,1,4,9,16]
y = [1,4,9,16,4,8,12,3]
label = [0,1,2,3,0,1,2,3]
colors = ['red','green','blue','purple']
fig = plt.figure(figsize=(8,8))
plt.scatter(x, y, c=label, cmap=matplotlib.colors.ListedColormap(colors))
cb = plt.colorbar()
loc = np.arange(0,max(label),max(label)/float(len(colors)))
cb.set_ticks(loc)
cb.set_ticklabels(colors)
Using a slightly modified version of this answer, one can generalise the above for N colors as follows:
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
N = 23 # Number of labels
# setup the plot
fig, ax = plt.subplots(1,1, figsize=(6,6))
# define the data
x = np.random.rand(1000)
y = np.random.rand(1000)
tag = np.random.randint(0,N,1000) # Tag each point with a corresponding label
# define the colormap
cmap = plt.cm.jet
# extract all colors from the .jet map
cmaplist = [cmap(i) for i in range(cmap.N)]
# create the new map
cmap = cmap.from_list('Custom cmap', cmaplist, cmap.N)
# define the bins and normalize
bounds = np.linspace(0,N,N+1)
norm = mpl.colors.BoundaryNorm(bounds, cmap.N)
# make the scatter
scat = ax.scatter(x,y,c=tag,s=np.random.randint(100,500,N),cmap=cmap, norm=norm)
# create the colorbar
cb = plt.colorbar(scat, spacing='proportional',ticks=bounds)
cb.set_label('Custom cbar')
ax.set_title('Discrete color mappings')
plt.show()
Which gives:
Also, you can use exists
select case when exists (select 1 from table)
then 'contains rows'
else 'doesnt contain rows'
end
or to check if there are child rows for a particular record :
select * from Table t1
where exists(
select 1 from ChildTable t2
where t1.id = t2.parentid)
or in a procedure
if exists(select 1 from table)
begin
-- do stuff
end

This shows locks. Sometimes things are going slow, but it's because it is blocked waiting for a lock:
select
object_name,
object_type,
session_id,

lmode, -- lock mode in which session holds lock
request,
block,
ctime -- Time since current mode was granted
from
v$locked_object, all_objects, v$lock
where
v$locked_object.object_id = all_objects.object_id AND
v$lock.id1 = all_objects.object_id AND
v$lock.sid = v$locked_object.session_id
order by
session_id, ctime desc, object_name

Visual Basic. I simply fail to understand its cryptic syntax, since it doesn't follow any programming convention. As a guy used to the syntax of C/C++ I may be partial though. But that doesn't undermine the fact that VB is THE worst language I've worked with.
You can use the available meta data:
DatabaseMetaData meta = con.getMetaData();
ResultSet res = meta.getTables(null, null, "My_Table_Name",
new String[] {"TABLE"});
while (res.next()) {
System.out.println(
" "+res.getString("TABLE_CAT")
+ ", "+res.getString("TABLE_SCHEM")
+ ", "+res.getString("TABLE_NAME")
+ ", "+res.getString("TABLE_TYPE")
+ ", "+res.getString("REMARKS"));
}
See here for more details. Note also the caveats in the JavaDoc.
For recent information on this issue (as of Sept 2015) consult this page.
Most information on this question here is obsolete.
What pyimagesearch is saying is that SURF/SIFT were moved to opencv_contrib
because of patent issues.
For installation there is also a nice page that tells you how to install opencv with opencv_contrib
and Python support so you get SURF/SIFT.
Notice that the API also changed. Now it's like this:
sift = cv2.xfeatures2d.SIFT_create()
Before I found the above pages, I also suffered quite a bit. But the pages listed do a very good job of helping with installation and explaining what's wrong.
The attribute packed
means that the compiler will not add padding between fields of the struct
. Padding is usually used to make fields aligned to their natural size, because some architectures impose penalties for unaligned access or don't allow it at all.
aligned(4)
means that the struct should be aligned to an address that is divisible by 4.
If the first item is to be used as a placeholder (empty value) and your select is required
then you can use the :invalid
pseudo-class to target it.
select {_x000D_
-webkit-appearance: menulist-button;_x000D_
color: black;_x000D_
}_x000D_
_x000D_
select:invalid {_x000D_
color: green;_x000D_
}
_x000D_
<select required>_x000D_
<option value="">Item1</option>_x000D_
<option value="Item2">Item2</option>_x000D_
<option value="Item3">Item3</option>_x000D_
</select>

To downplay the "magic" of this issue a little bit. You need an Internet connection after you make those changes. If for some reason required libraries cannot by downloaded, instead of giving an appropriate message (like "Failed to fetch libraries") you will simply get the same build error. Was struggling with this for an hour before realizing that my company's VPN blocked the repo.
Another way to rename the database or taking image of the database is by using Reverse engineering option in the database tab. It will create a ERR diagram for the database. Rename the schema there.
after that go to file menu and go to export and forward engineer the database.
Then you can import the database.
Basically it boils down to using a fixed-width page and setting the width for those labels and controls. This is the most common way in which table-less layouts are implemented.
There are many ways to go about setting widths. Blueprint.css is a very popular css framework which can help you set up columns/widths.
Well, personally I do not use numeric datatype to store phone numbers or related info.
How do you store a number say 001234567? It'll end up as 1234567, losing the leading zeros.
Of course you can always left-pad it up, but that's provided you know exactly how many digits the number should be.
This doesn't answer your entire post,
Just my 2 cents
When is the
finalize()
method called in Java?
The finalize method will be called after the GC detects that the object is no longer reachable, and before it actually reclaims the memory used by the object.
If an object never becomes unreachable, finalize()
will never be called on it.
If the GC doesn't run then finalize()
may never be called. (Normally, the GC only runs when the JVM decides that there is likely to enough garbage to make it worthwhile.)
It may take more than one GC cycle before the GC determines that a specific object is unreachable. (Java GCs are typically "generational" collectors ...)
Once the GC detects an object is unreachable and finalizable, it is places on a finalization queue. Finalization typically occurs asynchronously with the normal GC.
(The JVM spec actually allows a JVM to never run finalizers ... provided that it doesn't reclaim the space used by the objects. A JVM that was implemented this way would be crippled / useless, but it this behavior is "allowed".)
The upshot is that it is unwise to rely on finalization to do things that have to be done in a definite time-frame. It is "best practice" not to use them at all. There should be a better (i.e. more reliable) way to do whatever it is you are trying to do in the finalize()
method.
The only legitimate use for finalization is to clean up resources associated with objects that have been lost by application code. Even then, you should try to write the application code so that it doesn't lose the objects in the first place. (For example, use Java 7+ try-with-resources to ensure that close()
is always called ...)
I created a test class which writes into a file when the finalize() method is called by overriding it. It is not executed. Can anybody tell me the reason why it is not executing?
It is hard to say, but there are a few possibilities:
A call to Class#getResourceAsStream(String)
delegates to the class loader and the resource is searched in the class path. In other words, you current code won't work and you should put abc.txt
in WEB-INF/classes
, or in WEB-INF/lib
if packaged in a jar file.
Or use ServletContext.getResourceAsStream(String)
which allows servlet containers to make a resource available to a servlet from any location, without using a class loader. So use this from a Servlet:
this.getServletContext().getResourceAsStream("/WEB-INF/abc.txt") ;
But is there a way I can call getServletContext from my Web Service?
If you are using JAX-WS, then you can get a WebServiceContext
injected:
@Resource
private WebServiceContext wsContext;
And then get the ServletContext
from it:
ServletContext sContext= wsContext.getMessageContext()
.get(MessageContext.SERVLET_CONTEXT));
I use a NAnt Build Script to deploy to my different environments. I have it modify my config files via XPath depending on where they're being deployed to, and then it automagically puts them into that environment using Beyond Compare.
Takes a minute or two to setup, but you only need to do it once. Then batch files take over while I go get another cup of coffee. :)
Here's an article I found on it.
There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.
You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.
When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.
You can export to PNG without alpha in Preview. Simply open your image, choose export, select PNG, uncheck Alpha, and click Save. Preview also support batch export if you open all your images at once.
sed
If one would like to do this systematically for all external links, CSS is no option. However, one could run the following sed
command once the (X)HTML has been created from Markdown:
sed -i 's|href="http|target="_blank" href="http|g' index.html
This can be further automated in a single workflow when a Makefile
with build instructions is employed.
PS: This answer was written at a time when extension link_attributes
was not yet available in Pandoc.
Here it is. Add this code to your web.config file:
<system.webServer>
<rewrite>
<rules>
<rule name="Root Hit Redirect" stopProcessing="true">
<match url="^$" />
<action type="Redirect" url="/menu_1/MainScreen.aspx" />
</rule>
</rules>
</rewrite>
</system.webServer>
It will do 301 Permanent Redirect (URL will be changed in browser). If you want to have such "redirect" to be invisible (rewrite, internal redirect), then use this rule (the only difference is that "Redirect" has been replaced by "Rewrite"):
<system.webServer>
<rewrite>
<rules>
<rule name="Root Hit Redirect" stopProcessing="true">
<match url="^$" />
<action type="Rewrite" url="/menu_1/MainScreen.aspx" />
</rule>
</rules>
</rewrite>
</system.webServer>
You cannot append to an existing xlsx file with xlsxwriter
.
There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close()
which will then write all of the information to your xlsx file.
Similarly, you can use a method of your own to "append" to xlsx documents. I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet, and then I had to append a new sheet each time a test started as well. The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns...
i.e.
cells = []
for row in range(sheet.nrows):
cells.append([])
for col in range(sheet.ncols):
cells[row].append(workbook.cell(row, col).value)
You don't need arrays, though. For example, this works perfectly fine:
import xlrd
import xlsxwriter
from os.path import expanduser
home = expanduser("~")
# this writes test data to an excel file
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
sheet1 = wb.add_worksheet()
for row in range(10):
for col in range(20):
sheet1.write(row, col, "test ({}, {})".format(row, col))
wb.close()
# open the file for reading
wbRD = xlrd.open_workbook("{}/Desktop/test.xlsx".format(home))
sheets = wbRD.sheets()
# open the same file for writing (just don't write yet)
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
# run through the sheets and store sheets in workbook
# this still doesn't write to the file yet
for sheet in sheets: # write data from old file
newSheet = wb.add_worksheet(sheet.name)
for row in range(sheet.nrows):
for col in range(sheet.ncols):
newSheet.write(row, col, sheet.cell(row, col).value)
for row in range(10, 20): # write NEW data
for col in range(20):
newSheet.write(row, col, "test ({}, {})".format(row, col))
wb.close() # THIS writes
However, I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over (which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call .close()
).
you can just use element.remove()
This is an oldie, and there are a few solutions out there, but I came up with a shorter and simpler formula than any other I encountered, and it might be useful to anyone passing by.
I have named the colors list Colors
(A2:A7), and the array formula put in cell C2 is this (fixed):
=IFERROR(INDEX(Colors,MATCH(SUM(COUNTIF(C$1:C1,Colors)),COUNTIF(Colors,"<"&Colors),0)),"")
Use Ctrl+Shift+Enter
to enter the formula in C2, and copy C2 down to C3:C7.
Explanation with sample data {"red"; "blue"; "red"; "green"; "blue"; "black"}:
COUNTIF(Colors,"<"&Colors)
returns an array (#1) with the count of values that are smaller then each item in the data {4;1;4;3;1;0} (black=0 items smaller, blue=1 item, red=4 items). This can be translated to a sort value for each item.COUNTIF(C$1:C...,Colors)
returns an array (#2) with 1 for each data item that is already in the sorted result. In C2 it returns {0;0;0;0;0;0} and in C3 {0;0;0;0;0;1} because "black" is first in the sort and last in the data. In C4 {0;1;0;0;1;1} it indicates "black" and all the occurrences of "blue" are already present.SUM
returns the k-th sort value, by counting all the smaller values occurrences that are already present (sum of array #2).MATCH
finds the first index of the k-th sort value (index in array #1).IFERROR
is only to hide the #N/A
error in the bottom cells, when the sorted unique list is complete.To know how many unique items you have you can use this regular formula:
=SUM(IF(FREQUENCY(COUNTIF(Colors,"<"&Colors),COUNTIF(Colors,"<"&Colors)),1))
I have recently implemented the receipt printing simply by pressing a button on a web page, without having to enter the printer options. I have done it using EPSON javascript SDK for ePOS. I have test it on EPSON TM-m30 receipt printer.
Here is the sample code.
var printer = null;
var ePosDev = null;
function InitMyPrinter() {
console.log("Init Printer");
var printerPort = 8008;
var printerAddress = "192.168.198.168";
if (isSSL) {
printerPort = 8043;
}
ePosDev = new epson.ePOSDevice();
ePosDev.connect(printerAddress, printerPort, cbConnect);
}
//Printing
function cbConnect(data) {
if (data == 'OK' || data == 'SSL_CONNECT_OK') {
ePosDev.createDevice('local_printer', ePosDev.DEVICE_TYPE_PRINTER,
{'crypto': false, 'buffer': false}, cbCreateDevice_printer);
} else {
console.log(data);
}
}
function cbCreateDevice_printer(devobj, retcode) {
if (retcode == 'OK') {
printer = devobj;
printer.timeout = 60000;
printer.onreceive = function (res) { //alert(res.success);
console.log("Printer Object Created");
};
printer.oncoveropen = function () { //alert('coveropen');
console.log("Printer Cover Open");
};
} else {
console.log(retcode);
isRegPrintConnected = false;
}
}
function print(salePrintObj) {
debugger;
if (isRegPrintConnected == false
|| printer == null) {
return;
}
console.log("Printing Started");
printer.addLayout(printer.LAYOUT_RECEIPT, 800, 0, 0, 0, 35, 0);
printer.addTextAlign(printer.ALIGN_CENTER);
printer.addTextSmooth(true);
printer.addText('\n');
printer.addText('\n');
printer.addTextDouble(true, true);
printer.addText(CompanyName + '\n');
printer.addTextDouble(false, false);
printer.addText(CompanyHeader + '\n');
printer.addText('\n');
printer.addTextAlign(printer.ALIGN_LEFT);
printer.addText('DATE: ' + currentDate + '\t\t');
printer.addTextAlign(printer.ALIGN_RIGHT);
printer.addText('TIME: ' + currentTime + '\n');
printer.addTextAlign(printer.ALIGN_LEFT);
printer.addTextAlign(printer.ALIGN_RIGHT);
printer.addText('REGISTER: ' + RegisterName + '\n');
printer.addTextAlign(printer.ALIGN_LEFT);
printer.addText('SALE # ' + SaleNumber + '\n');
printer.addTextAlign(printer.ALIGN_CENTER);
printer.addTextStyle(false, false, true, printer.COLOR_1);

The only way I know to deal with this is to create a new workspace, import projects from the polluted workspace, reconstructing all my settings (a major pain) and then delete the old workspace. Is there an easier way to deal with this?
For synchronizing or restoring all our settings we use Workspace Mechanic. Once all the settings are recorded its one click and all settings are restored... You can also setup a server which provides those settings for all users.

I have a few tricks and work arounds to interesting 'features' of xtable and Latex that I'll share here.
Trick #1: Removing Duplicates in Columns and Trick #2: Using Booktabs
First, load packages and define my clean function
<<label=first, include=FALSE, echo=FALSE>>=
library(xtable)
library(plyr)
cleanf <- function(x){
oldx <- c(FALSE, x[-1]==x[-length(x)])
# is the value equal to the previous?
res <- x
res[oldx] <- NA
return(res)}
Now generate some fake data
data<-data.frame(animal=sample(c("elephant", "dog", "cat", "fish", "snake"), 100,replace=TRUE),
colour=sample(c("red", "blue", "green", "yellow"), 100,replace=TRUE),
size=rnorm(100,mean=500, sd=150),
age=rlnorm(100, meanlog=3, sdlog=0.5))
#generate a table
datatable<-ddply(data, .(animal, colour), function(df) {
return(data.frame(size=mean(df$size), age=mean(df$age)))
})
Now we can generate a table, and use the clean function to remove duplicate entries in the label columns.
cleandata<-datatable
cleandata$animal<-cleanf(cleandata$animal)
cleandata$colour<-cleanf(cleandata$colour)
@
this is a normal xtable
<<label=normal, results=tex, echo=FALSE>>=
print(
xtable(
datatable
),
tabular.environment='longtable',
latex.environments=c("center"),
floating=FALSE,
include.rownames=FALSE
)
@
this is a normal xtable where a custom function has turned duplicates to NA
<<label=cleandata, results=tex, echo=FALSE>>=
print(
xtable(
cleandata
),
tabular.environment='longtable',
latex.environments=c("center"),
floating=FALSE,
include.rownames=FALSE
)
@
This table uses the booktab package (and needs a \usepackage{booktabs} in the headers)
\begin{table}[!h]
\centering
\caption{table using booktabs.}
\label{tab:mytable}
<<label=booktabs, echo=F,results=tex>>=
mat <- xtable(cleandata,digits=rep(2,ncol(cleandata)+1))
foo<-0:(length(mat$animal))
bar<-foo[!is.na(mat$animal)]
print(mat,
sanitize.text.function = function(x){x},
floating=FALSE,
include.rownames=FALSE,
hline.after=NULL,
add.to.row=list(pos=list(-1,bar,nrow(mat)),
command=c("\\toprule ", "\\midrule ", "\\bottomrule ")))
#could extend this with \cmidrule to have a partial line over
#a sub category column and \addlinespace to add space before a total row
@
You can, once you escape the HTML correctly. This page shows what needs to be done.
If using PHP, you could use json_encode()
Hope this helps :)
Some other tests. Of course to do...
set([x for x in l if l.count(x) > 1])
...is too costly. It's about 500 times faster (the more long array gives better results) to use the next final method:
def dups_count_dict(l):
d = {}
for item in l:
if item not in d:
d[item] = 0
d[item] += 1
result_d = {key: val for key, val in d.iteritems() if val > 1}
return result_d.keys()
Only 2 loops, no very costly l.count()
operations.
Here is a code to compare the methods for example. The code is below, here is the output:
dups_count: 13.368s # this is a function which uses l.count()
dups_count_dict: 0.014s # this is a final best function (of the 3 functions)
dups_count_counter: 0.024s # collections.Counter

from time import time
from collections import Counter
class TimerCounter(object):
def __init__(self):
self._time_sum = 0
def start(self):
self.time = time()
def stop(self):
self._time_sum += time() - self.time
def get_time_sum(self):
return self._time_sum
def dups_count(l):
return set([x for x in l if l.count(x) > 1])
def dups_count_dict(l):
d = {}
for item in l:
if item not in d:
d[item] = 0
d[item] += 1
result_d = {key: val for key, val in d.iteritems() if val > 1}
return result_d.keys()
def dups_counter(l):

result_d = {key: val for key, val in counter.iteritems() if val > 1}

Just add @Transactional
annotation on top of your test:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"testContext.xml"})
@Transactional
public class StudentSystemTest {
By default Spring will start a new transaction surrounding your test method and @Before
/@After
callbacks, rolling back at the end. It works by default, it's enough to have some transaction manager in the context.
From: 10.3.5.4 Transaction management (bold mine):
In the TestContext framework, transactions are managed by the TransactionalTestExecutionListener. Note that
TransactionalTestExecutionListener
is configured by default, even if you do not explicitly declare@TestExecutionListeners
on your test class. To enable support for transactions, however, you must provide aPlatformTransactionManager
bean in the application context loaded by@ContextConfiguration
semantics. In addition, you must declare@Transactional
either at the class or method level for your tests.
Looks like TaskCache registry data is in ...
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache
... on my Windows 10 PC (i.e. add Schedule before TaskCache and TaskCache has an upper case C).
The simplest way is
>>> a = range(1, 10)
>>> for x in [2, 3, 7]:
... a.remove(x)
...
>>> a
[1, 4, 5, 6, 8, 9]
One possible problem here is that each time you call remove(), all the items are shuffled down the list to fill the hole. So if a
grows very large this will end up being quite slow.
This way builds a brand new list. The advantage is that we avoid all the shuffling of the first approach
>>> removeset = set([2, 3, 7])
>>> a = [x for x in a if x not in removeset]
If you want to modify a
in place, just one small change is required
>>> removeset = set([2, 3, 7])
>>> a[:] = [x for x in a if x not in removeset]
If you want to filter out extensions from the output of another command e.g. "git":
files=$(git diff --name-only --diff-filter=d origin/master... | grep -E '\.cpp$|\.h$')
for file in $files; do
echo "$file"
done
Starting with v0.20.0
, the dtype
keyword argument in read_excel()
function could be used to specify the data types that needs to be applied to the columns just like it exists for read_csv()
case.
Using converters
and dtype
arguments together on the same column name would lead to the latter getting shadowed and the former gaining preferance.
1) Inorder for it to not interpret the dtypes
but rather pass all the contents of it's columns as they were originally in the file before, we could set this arg to str
or object
so that we don't mess up our data. (one such case would be leading zeros in numbers which would be lost otherwise)
pd.read_excel('file_name.xlsx', dtype=str) # (or) dtype=object
2) It even supports a dict mapping wherein the keys
constitute the column names and values
it's respective data type to be set especially when you want to alter the dtype
for a subset of all the columns.
# Assuming data types for `a` and `b` columns to be altered
pd.read_excel('file_name.xlsx', dtype={'a': np.float64, 'b': np.int32})
This is the answer that was required but everybody answered only part one of many.
UTF-8
documentadvanced editors don't make it simple for you... go low level...
use notepad to save the document as meName.html & change the encoding
type to UTF-8
Step 2 - Mention in your html page that you are going to use such characters by
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
Step 3 - When you put in some characters make sure your container tags have the following 2 properties set
dir='rtl'
lang='ar'
example
<p dir="rtl" lang="ar" style="color:#e0e0e0;font-size:20px;">????? ??????? ??????</p>
NOTE: font type, font family, font face setting will have no effect on special characters
Basically it's designing your cell, The cellforrowatindexpath is called for each cell and the cell number is found by indexpath.row and section number by indexpath.section . Here you can use a label, button or textfied image anything that you want which are updated for all rows in the table. Answer for second question In cell for row at index path use an if statement
In Objective C
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(tableView == firstTableView)
{
//code for first table view
[cell.contentView addSubview: someView];
}
if(tableview == secondTableView)
{
//code for secondTableView
[cell.contentView addSubview: someView];
}
return cell;
}
In Swift 3.0
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
if(tableView == firstTableView) {
//code for first table view
}
if(tableview == secondTableView) {
//code for secondTableView
}
return cell
}
Code coverage is simply a measure of the code that is tested. There are a variety of coverage criteria that can be measured, but typically it is the various paths, conditions, functions, and statements within a program that makeup the total coverage. The code coverage metric is the just a percentage of tests that execute each of these coverage criteria.
As far as how I go about tracking unit test coverage on my projects, I use static code analysis tools to keep track.
First you need to define the List
as :
List<Map<String, ArrayList<String>>> list = new ArrayList<>();
To add the Map
to the List
, use add(E e) method :
list.add(map);
Actually, there are two foreign_key_checks
variables: a global variable and a local (per session) variable. Upon connection, the session variable is initialized to the value of the global variable.
The command SET foreign_key_checks
modifies the session variable.
To modify the global variable, use SET GLOBAL foreign_key_checks
or SET @@global.foreign_key_checks
.

In C, this is done using arguments passed to your main()
function:
int main(int argc, char *argv[])
{
int i = 0;
for (i = 0; i < argc; i++) {
printf("argv[%d] = %s\n", i, argv[i]);
}
return 0;
}
More information can be found online such as this Arguments to main article.
As final note the Mozilla documentation explicitly says that
The above example would fail if the header was wildcarded as: Access-Control-Allow-Origin: *. Since the Access-Control-Allow-Origin explicitly mentions http://foo.example, the credential-cognizant content is returned to the invoking web content.
As consequence is a not simply a bad practice to use '*'. Simply does not work :)

I tried Dave Ward's solution. The data part was not being sent from the browser in the payload part of the post request as the contentType is set to "application/json"
. Once I removed this line everything worked great.
var markers = [{ "position": "128.3657142857143", "markerPosition": "7" },
{ "position": "235.1944023323615", "markerPosition": "19" },
{ "position": "42.5978231292517", "markerPosition": "-3" }];
$.ajax({
type: "POST",
url: "/webservices/PodcastService.asmx/CreateMarkers",
// The key needs to match your method's input parameter (case-sensitive).
data: JSON.stringify({ Markers: markers }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data){alert(data);},
failure: function(errMsg) {
alert(errMsg);
}
});
With Android's Navigation component, this problem, when you have nested Fragments, could feel like an unsolvable mystery.
Based on knowledge and inspiration from the following answers in this post, I managed to make up a simple solution that works:
In your activity's onActivityResult()
, you can loop through the active Fragments list that you get using the FragmentManager
's getFragments()
method.
Please note that for you to do this, you need to be using the getSupportFragmentManager()
or targeting API 26 and above.
The idea here is to loop through the list checking the instance type of each Fragment in the list, using instanceof
.
While looping through this list of type Fragment
is ideal, unfortunately, when you're using the Android Navigation Component, the list will only have one item, i.e. NavHostFragment
.
So now what? We need to get Fragments known to the NavHostFragment
. NavHostFragment
in itself is a Fragment. So using getChildFragmentManager().getFragments()
, we once again get a List<Fragment>
of Fragments known to our NavHostFragment
. We loop through that list checking the instanceof
each Fragment.
Once we find our Fragment of interest in the list, we call its onActivityResult()
, passing to it all the parameters that the Activity's onActivityResult()
declares.
// Your activity's onActivityResult()_x000D_
_x000D_
@Override_x000D_
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {_x000D_
super.onActivityResult(requestCode, resultCode, data);_x000D_
_x000D_
List<Fragment> lsActiveFragments = getSupportFragmentManager().getFragments();_x000D_
for (Fragment fragmentActive : lsActiveFragments) {_x000D_
_x000D_
if (fragmentActive instanceof NavHostFragment) {_x000D_
_x000D_
List<Fragment> lsActiveSubFragments = fragmentActive.getChildFragmentManager().getFragments();_x000D_
for (Fragment fragmentActiveSub : lsActiveSubFragments) {_x000D_
_x000D_
if (fragmentActiveSub instanceof FragWeAreInterestedIn) {_x000D_
fragmentActiveSub.onActivityResult(requestCode, resultCode, data);_x000D_
}_x000D_
_x000D_
}_x000D_
_x000D_
}_x000D_
_x000D_
}_x000D_
_x000D_
}
_x000D_
$.active
returns the number of active Ajax requests.

That's because abc
is undefined at the moment of the template rendering. You can use safe navigation operator (?
) to "protect" template until HTTP call is completed:
{{abc?.xyz?.name}}
You can read more about safe navigation operator here.
Update:
Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf
directive to overcome this problem:
<div *ngIf="arr && arr.length > 0">
{{arr[0].name}}
</div>
Read more about NgIf
directive here.
public string ReplaceFirst(string text, string search, string replace)
{
int pos = text.IndexOf(search);
if (pos < 0)
{
return text;
}
return text.Substring(0, pos) + replace + text.Substring(pos + search.Length);
}
here is an Extension Method that could also work as well per VoidKing
request
public static class StringExtensionMethods
{
public static string ReplaceFirst(this string text, string search, string replace)
{
int pos = text.IndexOf(search);
if (pos < 0)
{
return text;
}
return text.Substring(0, pos) + replace + text.Substring(pos + search.Length);
}
}
This is actually easier than it seems.
grep -Rl 'foo' ./ | xargs -n 1 -I % sh -c "ls %; sed -i 's/foo/bar/g' %";
Easy peasy. If you get a good grasp on find, grep, xargs, sed, and awk, almost nothing is impossible when it comes to text file manipulation in bash :)
The question does not make clear what exactly you want to achieve.
List has the append
method, which appends its argument to the list:
>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.append(list_two)
>>> list_one
[1, 2, 3, [4, 5, 6]]
There's also the extend
method, which appends items from the list you pass as an argument:
>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.extend(list_two)
>>> list_one
[1, 2, 3, 4, 5, 6]
And of course, there's the insert
method which acts similarly to append
but allows you to specify the insertion point:
>>> list_one.insert(2, list_two)
>>> list_one
[1, 2, [4, 5, 6], 3, 4, 5, 6]
To extend a list at a specific insertion point you can use list slicing (thanks, @florisla):
>>> l = [1, 2, 3, 4, 5]
>>> l[2:2] = ['a', 'b', 'c']
>>> l
[1, 2, 'a', 'b', 'c', 3, 4, 5]
List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:
>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]
Using Common Table Expression (CTE)
WITH CTE AS(
SELECT ROW_NUMBER() OVER(ORDER BY CustomerId) AS RowNumber,
Customers.*
FROM Customers
)
SELECT * FROM CTE
Alternatively you can write the same like
{
test: /\.(svg|png|jpg|jpeg|gif)$/,
include: 'path of input image directory',
use: {
loader: 'file-loader',
options: {
name: '[path][name].[ext]',
outputPath: 'path of output image directory'
}
}
}
and then use simple import
import varName from 'relative path';
and in jsx write like
<img src={varName} ..../>
....
are for other image attributes
ASCX files are server-side Web application framework designed for Web development to produce dynamic Web pages.They like DLL codes but you can use there's TAGS You can write them once and use them in any places in your ASP pages.If you have a file named "Controll.ascx" then its code will named "Controll.ascx.cs". You can embed it in a ASP page to use it:
It's easy to create this yourself
In your layout include the following ProgressBar
with a specific drawable (note you should get the width from dimensions instead). The max value is important here:
<ProgressBar
android:id="@+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:max="500"
android:progress="0"
android:progressDrawable="@drawable/circular" />
Now create the drawable in your resources with the following shape. Play with the radius (you can use innerRadius
instead of innerRadiusRatio
) and thickness values.
circular (Pre Lollipop OR API Level < 21)
<shape
android:innerRadiusRatio="2.3"
android:shape="ring"
android:thickness="3.8sp" >
<solid android:color="@color/yourColor" />
</shape>
circular ( >= Lollipop OR API Level >= 21)
<shape
android:useLevel="true"
android:innerRadiusRatio="2.3"
android:shape="ring"
android:thickness="3.8sp" >
<solid android:color="@color/yourColor" />
</shape>
useLevel is "false" by default in API Level 21 (Lollipop) .
Start Animation
Next in your code use an ObjectAnimator
to animate the progress field of the ProgessBar
of your layout.
ProgressBar progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", 0, 500); // see this max value coming back here, we animate towards that value
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();
Stop Animation
progressBar.clearAnimation();
P.S. unlike examples above, it give smooth animation.
To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.
I chose to use double quotes because they are easier to see.
Only a few characters in the Windows code page 1252 (Latin-1) are not allowed as names. Note that the Windows Explorer will strip leading spaces from names and not allow you to call a files space dot something (like ?.txt
), although this is allowed in the file system! Only a space and no file extension is invalid however.
If you create files through e.g. a Python script (this is what I did), then you can easily find out what is actually allowed and in what order the characters get sorted. The sort order varies based on your locale! Below are the results of my script, run with Python 2.7.15 on a German Windows 10 Pro 64bit:

Screenshot of how Explorer sorts the files for me:
The highlighted file with the ? white smiley face was added manually by me (Alt+1) to show where this Unicode character (U+263A) ends up, see Jimbugs' answer.
The first file has a space as name (0x20), the second is the non-breaking space (0xa0). The files in the bottom half of the third row which look like they have no name use the characters with hex codes 0x81, 0x8D, 0x8F, 0x90, 0x9D (in this order from top to bottom).

I'm afraid I'm unable to test this at the moment, but in the past, I believe I had to give each option tag an ID, and then I did something like:
document.getElementById("optionID").select();
If that doesn't work, maybe it'll get you closer to a solution :P
I will put here some real case examples and scenarios when to use one or another, it might be of help for somebody else:
HashMap
When you have to use cache in your application. Redis and membase are some type of extended HashMap. (Doesn't matter the order of the elements, you need quick ( O(1) ) read access (a value), using a key).
LinkedList
When the order is important (they are ordered as they were added to the LinkedList), the number of elements are unknown (don't waste memory allocation) and you require quick insertion time ( O(1) ). A list of to-do items that can be listed sequentially as they are added is a good example.
Edit filename: core/Common.php, line number: 257
Before
return $_config[0] =& $config;
After
$_config[0] =& $config;
return $_config[0];
Added by NikiC
In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).
This fix has been merged into CI 2.2.1 (https://github.com/bcit-ci/CodeIgniter/commit/69b02d0f0bc46e914bed1604cfbd9bf74286b2e3). It's better to upgrade rather than modifying core framework files.
In this example, you may show your menu centered.
<div id="main-menu-container">
<div id="main-menu">
//your menu
</div>
</div>
.f-nav{ /* To fix main menu container */
z-index: 9999;
position: fixed;
left: 0;
top: 0;
width: 100%;
}
#main-menu-container {
text-align: center; /* Assuming your main layout is centered */
}
#main-menu {
display: inline-block;
width: 1024px; /* Your menu's width */
}
$("document").ready(function($){
var nav = $('#main-menu-container');
$(window).scroll(function () {
if ($(this).scrollTop() > 125) {
nav.addClass("f-nav");
} else {
nav.removeClass("f-nav");
}
});
});
