I have this problem, but:
String content = "<html><head><meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\" /></head><body>";
content += mydata + "</body></html>";
WebView1.loadData(content, "text/html", "UTF-8");
not work in all devices. And I merge some methods:
String content =
"<?xml version=\"1.0\" encoding=\"UTF-8\" ?>"+
"<html><head>"+
"<meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\" />"+
"</head><body>";
content += myContent + "</body></html>";
WebView WebView1 = (WebView) findViewById(R.id.webView1);
WebView1.loadData(content, "text/html; charset=utf-8", "UTF-8");
It works.
In Android Studio 3.4, In the case in which Logcat does not appear in View->ToolWindows->Logcat
(in that case Alt+6
or CMD+6
will also not work), the way to get the logact window is:
File->Profile or debug APK
(choose an APK)View->ToolWindows->Logcat
) or through Alt+6
or
CMD+6
This issue is an indication that something is not configured correctly with the Android Studio project. The above solution can be useful:
You need to look at the return value of the call to showConfirmDialog
. I.E.:
int dialogResult = JOptionPane.showConfirmDialog (null, "Would You Like to Save your Previous Note First?","Warning",dialogButton);
if(dialogResult == JOptionPane.YES_OPTION){
// Saving code here
}
You were testing against dialogButton
, which you were using to set the buttons that should be displayed by the dialog, and this variable was never updated - so dialogButton
would never have been anything other than JOptionPane.YES_NO_OPTION
.
Per the Javadoc for showConfirmDialog
:
Returns: an integer indicating the option selected by the user
Try this:
SELECT GETDATE(), 'Today'
UNION ALL
SELECT DATEADD(DAY, 10, GETDATE()), '10 Days Later'
UNION ALL
SELECT DATEADD(DAY, –10, GETDATE()), '10 Days Earlier'
UNION ALL
SELECT DATEADD(MONTH, 1, GETDATE()), 'Next Month'
UNION ALL
SELECT DATEADD(MONTH, –1, GETDATE()), 'Previous Month'
UNION ALL
SELECT DATEADD(YEAR, 1, GETDATE()), 'Next Year'
UNION ALL
SELECT DATEADD(YEAR, –1, GETDATE()), 'Previous Year'

To resize the storage of the Android emulator in Linux:
1) install qemu
2) Locate the directory containing the img files of the virtual machine. Something like ~/.android/avd/.avd and cd to it.
3) Resize the ext4 images: i.e. for growing from 500Mb to 4Gb execute
qemu-img resize userdata.img +3.5GB
qemu-img resize userdata-qemu.img +3.5GB
4) grow the filesystem:
e2fsck -f userdata.img
resize2fs userdata.img
e2fsck -f userdata-qemu.img
resize2fs userdata-qemu.img
5) For the sd card image, optional: rescue the data:
mkdir 1
mount -o loop sdcard.img 1
cp -a 1 2
umount 1
6) resize the image from 100Mb to Gb:
qemu-img resize sdcard.img +3.9GB
7) re-generate the filesystem:
mkfs.vfat sdcard.img
8) optional: restore the old data:
mount -o loop sdcard.img 1
cp -a 2/* 1
mount -o loop sdcard.img 1

from somenames
Sample table
create table somenames (Name varchar(100))
insert somenames select 'abcd efgh'
insert somenames select 'ijk lmn opq'
insert somenames select 'asd j. asdjja'
insert somenames select 'asb (asdfas) asd'
insert somenames select 'asd'
insert somenames select ''
insert somenames select null
Naturally, my approach was to loop through the first array once and check the index of each value in the second array. If the index is > -1
, then push
it onto the returned array.
?Array.prototype.diff = function(arr2) {
var ret = [];
for(var i in this) {
if(arr2.indexOf(this[i]) > -1){
ret.push(this[i]);
}
}
return ret;
};
?
My solution doesn't use two loops like others do so it may run a bit faster. If you want to avoid using for..in
, you can sort both arrays first to reindex all their values:
Array.prototype.diff = function(arr2) {
var ret = [];
this.sort();
arr2.sort();
for(var i = 0; i < this.length; i += 1) {
if(arr2.indexOf(this[i]) > -1){
ret.push(this[i]);
}
}
return ret;
};
Usage would look like:
var array1 = ["cat", "sum","fun", "run", "hut"];
var array2 = ["bat", "cat","dog","sun", "hut", "gut"];
console.log(array1.diff(array2));
If you have an issue/problem with extending the Array prototype, you could easily change this to a function.
var diff = function(arr, arr2) {
And you'd change anywhere where the func originally said this
to arr2
.

Beware of NULLS.
Today I came across a very strange behaviour of query while using IN and NOT IN
operators. Actually I wanted to compare two tables and find out whether a value from table b
existed in table a
or not and find out its behavior if the column containsnull
values. So I just created an environment to test this behavior.
We will create table table_a
.
SQL> create table table_a ( a number);
Table created.
We will create table table_b
.
SQL> create table table_b ( b number);
Table created.
Insert some values into table_a
.
SQL> insert into table_a values (1);
1 row created.
SQL> insert into table_a values (2);
1 row created.
SQL> insert into table_a values (3);
1 row created.
Insert some values into table_b
.
SQL> insert into table_b values(4);
1 row created.
SQL> insert into table_b values(3);
1 row created.
Now we will execute a query to check the existence of a value in table_a
by checking its value from table_b
using IN
operator.
SQL> select * from table_a where a in (select * from table_b);
A
----------
3
Execute below query to check the non existence.
SQL> select * from table_a where a not in (select * from table_b);
A
----------
1
2
The output came as expected. Now we will insert a null
value in the table table_b
and see how the above two queries behave.
SQL> insert into table_b values(null);
1 row created.
SQL> select * from table_a where a in (select * from table_b);
A
----------
3
SQL> select * from table_a where a not in (select * from table_b);
no rows selected
The first query behaved as expected but what happened to the second query? Why didn't we get any output, what should have happened? Is there any difference in the query? No.
The change is in the data of table table_b
. We have introduced a null
value in the table. But how come it's behaving like this? Let's split the two queries into "AND"
and "OR"
operator.
The first query will be handled internally something like this. So a null
will not create a problem here as my first two operands will either evaluate to true
or false
. But my third operand a = null
will neither evaluate to true
nor false
. It will evaluate to null
only.
select * from table_a whara a = 3 or a = 4 or a = null;
a = 3 is either true or false
a = 4 is either true or false
a = null is null
The second query will be handled as below. Since we are using an "AND"
operator and anything other than true
in any of the operand will not give me any output.
select * from table_a whara a <> 3 and a <> 4 and a <> null;
a <> 3 is either true or false
a <> 4 is either true or false
a <> null is null
So how do we handle this? We will pick all the not null
values from table table_b
while using NOT IN
operator.
SQL> select * from table_a where a not in (select * from table_b where b is not null);
A
----------
1
2
So always be careful about NULL
values in the column while using NOT IN
operator.
Beware of NULL!!
Expanding upon Gustavo Lima's answer. The same thing can be done without creating an entirely new list. The values in the list can be replaced with the differentials as the FOR
loop progresses.
def f_ClosestVal(v_List, v_Number):
"""Takes an unsorted LIST of INTs and RETURNS INDEX of value closest to an INT"""
for _index, i in enumerate(v_List):
v_List[_index] = abs(v_Number - i)
return v_List.index(min(v_List))
myList = [1, 88, 44, 4, 4, -2, 3]
v_Num = 5
print(f_ClosestVal(myList, v_Num)) ## Gives "3," the index of the first "4" in the list.
It is specifically mentioned in the documentation as part of Entity SQL. Are you getting an error message?
// LIKE and ESCAPE
// If an AdventureWorksEntities.Product contained a Name
// with the value 'Down_Tube', the following query would find that
// value.
Select value P.Name FROM AdventureWorksEntities.Product
as P where P.Name LIKE 'DownA_%' ESCAPE 'A'
// LIKE
Select value P.Name FROM AdventureWorksEntities.Product
as P where P.Name like 'BB%'
Abstraction: what are the minimum functions and variables that should be exposed to the outside of our class.
Encapsulation: how to achieve this requirement, meaning how to implement it.
First Add a Class called Win32.cs
public class Win32
{
[DllImport("User32.Dll")]
public static extern long SetCursorPos(int x, int y);
[DllImport("User32.Dll")]
public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
public int x;
public int y;
public POINT(int X, int Y)
{
x = X;
y = Y;
}
}
}
You can use it then like this:
Win32.POINT p = new Win32.POINT(xPos, yPos);
Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);
var persons = new List<Person>
{
new Person {ID = 1, Name = "jhon", Salary = 2500},
new Person {ID = 2, Name = "Sena", Salary = 1500},
new Person {ID = 3, Name = "Max", Salary = 5500},
new Person {ID = 4, Name = "Gen", Salary = 3500}
};
var acertainperson = persons.Where(p => p.Name == "jhon").First();
Console.WriteLine("{0}: {1} points",
acertainperson.Name, acertainperson.Salary);
jhon: 2500 points
var doingprettywell = persons.Where(p => p.Salary > 2000);
foreach (var person in doingprettywell)
{
Console.WriteLine("{0}: {1} points",
person.Name, person.Salary);
}
jhon: 2500 points
Max: 5500 points
Gen: 3500 points
var astupidcalc = from p in persons
where p.ID > 2
select new
{
Name = p.Name,
Bobos = p.Salary*p.ID,
Bobotype = "bobos"
};
foreach (var person in astupidcalc)
{
Console.WriteLine("{0}: {1} {2}",
person.Name, person.Bobos, person.Bobotype);
}
Max: 16500 bobos
Gen: 14000 bobos
If you are using the new** Gradle build system then getPackageName
will oddly return application Id, not package name. So MasterGaurav's answer is correct but he doesn't need to start off with ++
If by application id, you're referring to package name...
See more about the differences here.
** not so new at this point
++ I realize that his answer made perfect sense in 2011
This will work from JS without coupling to HTML:
document.getElementById("click-button").onclick = onClickFunction;
function onClickFunction()
{
return functionWithArguments('You clicked the button!');
}
function functionWithArguments(text) {
document.getElementById("some-div").innerText = text;
}
From your Obc-C code I think you want to set an Image for button so try this way:
let playButton = UIButton(type: .Custom)
if let image = UIImage(named: "play.png") {
playButton.setImage(image, forState: .Normal)
}
In Short:
playButton.setImage(UIImage(named: "play.png"), forState: UIControlState.Normal)
For Swift 3:
let playButton = UIButton(type: .custom)
playButton.setImage(UIImage(named: "play.png"), for: .normal)
When you have changes on your working copy, from command line do:
git stash
This will stash your changes and clear your status report
git pull
This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge
git stash pop
This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.
if you need to see what is in your stash
git stash list
SqlConnection con = new SqlConnection(@"Some Connection String");
SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);
da.SelectCommand.CommandType = CommandType.StoredProcedure;
da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123;
DataTable dt = new DataTable();
da.Fill(dt);
dataGridView1.DataSource = dt;
In the Hibernate Manual you can see this example
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
for (int i = 0; i < 100000; i++) {
Customer customer = new Customer(...);
session.save(customer);
if (i % 20 == 0) { // 20, same as the JDBC batch size
// flush a batch of inserts and release memory:
session.flush();
session.clear();
}
}
tx.commit();
session.close();
Without the call to the flush method, your first-level cache would throw an OutOfMemoryException
In my case, this error message shown when I don't added optional property to constructor.
struct Event: Identifiable, Codable {
var id: String
var summary: String
var description: String?
// also has other props...
init(id: String, summary: String, description: String?){
self.id = id
self.summary = summary
self.description = description
}
}
// skip pass description
// It show message "Type of expression is ambiguous without more context"
Event(
id: "1",
summary: "summary",
)
// pass description explicity pass nil to description
Event(
id: "1",
summary: "summary",
description: nil
)
but it looks always not occured.
I test in my playground this code, it show warning about more concrete
var str = "Hello, playground"
struct User {
var id: String
var name: String?
init(id: String, name: String?) {
self.id = id
self.name = name
}
}
User(id: "hoge") // Missing argument for parameter 'name' in call
Good question. But I think there is no good answer which fits your criteria. The best I can think of is to use an extra vars file.
A task like this:
- include_vars: concat.yml
And in concat.yml
you have your definition:
newvar: "{{ var1 }}-{{ var2 }}-{{ var3 }}"
There are so many answers here suggesting to escape the dot with \.
but I have been running into this issue over and over again: \.
gives me the same result as .
However, these two expressions work for me:
$ grep -r 0\\.49 *
And:
$ grep -r 0[.]49 *
I'm using a "normal" bash shell on Ubuntu and Archlinux.
Edit, or, according to comments:
$ grep -r '0\.49' *
Note, the single-quotes doing the difference here.
It will merger two array and remove duplicate
<?php
$first = 'your first array';
$second = 'your second array';
$result = array_merge($first,$second);
print_r($result);
$result1= array_unique($result);
print_r($result1);
?>
Try this link link1
int rand = (new Random()).getNextInt(900000) + 100000;
EDIT: Fixed off-by-1 error and removed invalid solution.
Well, to exactly answer your question title :-)
var lastPartOfCurrentDirectoryName =
Path.GetFileName(Environment.CurrentDirectory);
I'm working in a legacy codebase trying to migrate to Vue.
In my specific situation (scrollable div wrapped in a bootstrap modal), a v-if showed new content, which I wanted the page to scroll down to. In order to get this behaviour to work, I had to wait for vue to finish re-rendering, and then use jQuery to scroll to the bottom of the modal.
So...
this.$nextTick(function() {
$('#thing')[0].scrollTop = $('#thing')[0].scrollHeight;
})
For anyone looking for a complete explanation, I recommend you to take a look at Content Security Policy: https://www.html5rocks.com/en/tutorials/security/content-security-policy/.
"Code from https://mybank.com should only have access to https://mybank.com’s data, and https://evil.example.com should certainly never be allowed access. Each origin is kept isolated from the rest of the web"
XSS attacks are based on the browser's inability to distinguish your app's code from code downloaded from another website. So you must whitelist the content origins that you consider safe to download content from, using the Content-Security-Policy
HTTP header.
This policy is described using a series of policy directives, each of which describes the policy for a certain resource type or policy area. Your policy should include a default-src policy directive, which is a fallback for other resource types when they don't have policies of their own.
So, if you modify your tag to:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *;**script-src 'self' http://onlineerp.solution.quebec 'unsafe-inline' 'unsafe-eval';** ">
You are saying that you are authorizing the execution of JavaScript code (script-src
)
from the origins 'self'
, http://onlineerp.solution.quebec
, 'unsafe-inline'
, 'unsafe-eval'
.
I guess that the first two are perfectly valid for your use case, I am a bit unsure about the other ones. 'unsafe-line'
and 'unsafe-eval'
pose a security problem, so you should not be using them unless you have a very specific need for them:
"If eval and its text-to-JavaScript brethren are completely essential to your application, you can enable them by adding 'unsafe-eval' as an allowed source in a script-src directive. But, again, please don’t. Banning the ability to execute strings makes it much more difficult for an attacker to execute unauthorized code on your site." (Mike West, Google)
var day = value.Date; // a DateTime that will just be whole days
var time = value.TimeOfDay; // a TimeSpan that is the duration into the day
i guess that you have a different class name in p1.java
The Observable Collection constructor will take an IList or an IEnumerable.
If you find that you are going to do this a lot you can make a simple extension method:
public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> enumerable)
{
return new ObservableCollection<T>(enumerable);
}
None of these answers worked for me. This answer doesn't solve OP's issue but since this post is the only one that shows up on googling this issue, I'm sharing my answer here.
I came across this issue while writing unit tests for Android. The issue was that the activity that I was testing extended AppCompatActivity
instead of Activity
. To fix this, I was able to just replace AppCompatActivity
with Activity
since I didn't really need it. This might not be a viable solution for everyone, but hopefully knowing the root cause will help someone.
At my Version the function to get the lenght or size was Count()
You're Welcome, hope it help someone.
There are various tricky issues with having multiple versions of Java (Apple's own Java 6 and Oracle JDK 7 or even 8) on one's Mac OS X system, and using different versions for different applications. I spent some time writing up my experience of my experience of installing and configuring various versions of JDK on Mac OS X 10.9.2.
In practice, the + symbol is placed directly in the conditional statement and on the side of the optional table (the one which is allowed to contain empty or null values within the conditional).
Some Mysql versions disallow 'limit' inside of a sub select. My answer to you (and me in the future) would be to use groups
select firstName,Lastname,id
where {whatever}
group by id
having max(id)
This allows you to return whatever you want in the select area, without having an aggregate field.
first install bootstrap in your project using npm
npm i bootstrap
after that open ur style.css file in your project and add this line
@import "~bootstrap/dist/css/bootstrap.css";
and that's it bootstrap added in your project
You could write a function that will convert and format this array as string. Even better: use FireBug for debugging instead of alerts.
Well, you have some options.
You could configure sudo to not prompt for a password. This is not recommended, due to the security risks.
You could write an expect script to read the password and supply it to sudo when required, but that's clunky and fragile.
I would recommend designing the script to run as root and drop its privileges whenever they're not needed. Simply have it sudo -u someotheruser command
for the commands that don't require root.
(If they have to run specifically as the user invoking the script, then you could have the script save the uid and invoke a second script via sudo with the id as an argument, so it knows who to su to..)
copied from polyfill Array.prototype.find code of Array.find, and added the array as first parameter.

Let’s say I have a HTTP Basic Auth realm named “Password protected”, and Bob is logged in. To log out I make 2 AJAX requests:
WWW-Authenticate: Basic realm="Password protected"
At this point browser forgot Bob’s credentials.
UPDATE: I have taken all of your input and came up with the following solution:
In code behind:
protected void Page_Load(object sender, EventArgs e)
{
Page.ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
}
In aspx page:
function CloseWindow() {
window.close();
}
If you are using bash you can try alias:
into the .bashrc file add this line:
alias p='cd /home/serdar/my_new_folder/path/'
when you write "p" on the command line, it will change the directory.
It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return
statement. When the code goes down that path, the function ends with no value returned, and so returns None
.
Updated: It sounds like your code looks like this:
def b(self, p, data):
current = p
if current.data == data:
return True
elif current.data == 1:
return False
else:
self.b(current.next, data)
That else clause is your None
path. You need to return the value that the recursive call returns:
else:
return self.b(current.next, data)
BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.
As others already replied, it's late to write unit tests, but not too late. The question is whether your code is testable or not. Indeed, it's not easy to put existing code under test, there is even a book about this: Working Effectively with Legacy Code (see key points or precursor PDF).
Now writing the unit tests or not is your call. You just need to be aware that it could be a tedious task. You might tackle this to learn unit-testing or consider writing acceptance (end-to-end) tests first, and start writing unit tests when you'll change the code or add new feature to the project.
Using Android Studio 3.0 or later version it is possible to pull database (also shared preference, cache directory and others) if application runs in debug mode on non-rooted device.
To pull database using android studio follow these steps.
You can use \
to indicate that any line of Ruby continues on the next line. This works with strings too:
string = "this is a \
string that spans lines"
puts string.inspect
will output "this is a string that spans lines"

In TortoiseGit, you can do the same thing under "Push..." options "Force: May discard" and checking "known changes".
Force (May discard known changes) allows the remote repository to accept a safer non-fast-forward push. This can cause the remote repository to lose commits; use it with care. This can prevent from losing unknown changes from other people on the remote. It checks if the server branch points to the same commit as the remote-tracking branch (known changes). If yes, a force push will be performed. Otherwise it will be rejected. Since git does not have remote-tracking tags, tags cannot be overwritten using this option.
Your code is way more cluttered than necessary.
Replace (Not (X Is Nothing))
with X IsNot Nothing
and omit the outer parentheses:
If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
For i As Integer = 0 To comp.Container.Components.Count() - 1
fixUIIn(comp.Container.Components(i), style)
Next
End If
Much more readable. … Also notice that I’ve removed the redundant Step 1
and the probably redundant .Item
.
But (as pointed out in the comments), index-based loops are out of vogue anyway. Don’t use them unless you absolutely have to. Use For Each
instead:
If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
For Each component In comp.Container.Components
fixUIIn(component, style)
Next
End If
Update (2010/10/01): Yesss, Sun Java Finally Uploaded To The Ubuntu 10.10 Maverick Official Partner Repository.
Update (2010/09/27): Readers might want to check Sun Java6 Packages [updated]. I still expect official packages to be available in the partner repos at releast time though.
For an unknown reason, the sun-java6-jdk are not yet available in the partner repositories.
So either downloaded the required packages from http://archive.canonical.com/pool/partner/s/sun-java6/ and install them with dpkg -i
.
Or temporarily replace the maverick partner repository
http://archive.canonical.com/ubuntu maverick partner
by the lucid one (replace maverick
by lucid
in the above line, let me know if you need more help to do this). Then, install sun-java6. And revert the change.
Besides the solution of using an additional list and calling addAll to insert the new items after the iteration (as e.g. the solution by user Nat), you can also use concurrent collections like the CopyOnWriteArrayList.
The "snapshot" style iterator method uses a reference to the state of the array at the point that the iterator was created. This array never changes during the lifetime of the iterator, so interference is impossible and the iterator is guaranteed not to throw ConcurrentModificationException.
With this special collection (usually used for concurrent access) it is possible to manipulate the underlying list while iterating over it. However, the iterator will not reflect the changes.
Is this better than the other solution? Probably not, I don't know the overhead introduced by the Copy-On-Write approach.
As of July 2012, the WebAudio API is now supported in Chrome, and at least partly supported in Firefox, and is slated to be added to IOS as of version 6.
Although it is robust enough to be used programatically for basic tasks, the Audio element was never meant to provide full audio support for games, etc. It was designed to allow a single piece of media to be embedded in a page, similar to an img tag. There are a lot of issues with trying to use the Audio tag for games:
I used this Getting Started With WebAudio article to get started with the WebAudio API. The FieldRunners WebAudio Case Study is also a good read.
If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:
Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:
In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

Immutable :
When you do some operation on a object, it creates a new object hence state is not modifiable as in case of string.
Mutable
When you perform some operation on a object, object itself modified no new obect created as in case of StringBuilder
Here is an R
version based on the @Pirijan answer above.
points <- 8
radius <- 10
center_x <- 5
center_y <- 5
drawCirclePoints <- function(points, radius, center_x, center_y) {
slice <- 2 * pi / points
angle <- slice * seq(0, points, by = 1)
newX <- center_x + radius * cos(angle)
newY <- center_y + radius * sin(angle)
plot(newX, newY)
}
drawCirclePoints(points, radius, center_x, center_y)
You can use the below syntax -
from FolderName.FileName import Classname
ls | xargs find 2>/dev/null | egrep /\.git$ | xargs rm -rf
This command (and it is just one command) will recursively remove .git directories (and files) that are in a directory without deleting the top-level git repo, which is handy if you want to commit all of your files without managing any submodules.
find 2>/dev/null | egrep /\.git$ | xargs rm -rf
This command will do the same thing, but will also delete the .git folder from the top-level directory.
If you have JQuery loaded already, you can just do this:
$('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');
EDIT:
First load JQuery in the head tag:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
Then call the Javascript to change the background image when something happens on the page, like when it finishes loading:
<script type="text/javascript">
$(document).ready(function() {
$('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');
});
</script>
Step :1)Remove the existing files using this command
find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch
Step : 2)Add .DS_Store in your .gitignore file
Step :3) Commit your changes in .gitignore git add .gitignore git commit -m "removed .DS_Store"

And that's all. For me is ok.
Hope this helps.
If you're using puma (I'm using this on Rails 6+):
To change default port for all environments:
The "{3000}" part sets the default port if undefined in ENV.
~/config/puma.rb
change:
port ENV.fetch('PORT') { 3000 }
for:
port ENV.fetch('PORT') { 10524 }
To define it depending on the environment, using Figaro gem for credentials/environment variable:
~/application.yml
local_db_username: your_user_name
?local_db_password: your_password
PORT: 10524
You can adapt this to you own environment variable manager.
For Russian symbols 'windows-1251'
<form action="yourProcessPage.php" method="POST" accept-charset="utf-8">
<input name="string" value="string" />
...
</form>
When simply convert string to cp1251
$string = $_POST['string'];
$string = mb_convert_encoding($string, "CP1251", "UTF-8");
Surely using array_map
and if using a container implementing ArrayAccess
to derive objects is just a smarter, semantic way to go about this?
Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.
For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN()
clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait
cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.
<?php
$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);
vs
<?php
$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
$arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);
If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr
you could always $arr = array_map
and be explicit.
There is a way that might be a little bit longer, but it works fine. This is a method to sort an int array descendingly.
Hope that this will help someone ,,, some day:
public static int[] sortArray (int[] array) {
int [] sortedArray = new int[array.length];
for (int i = 0; i < sortedArray.length; i++) {
sortedArray[i] = array[i];
}
boolean flag = true;
int temp;
while (flag) {
flag = false;
for (int i = 0; i < sortedArray.length - 1; i++) {
if(sortedArray[i] < sortedArray[i+1]) {
temp = sortedArray[i];
sortedArray[i] = sortedArray[i+1];
sortedArray[i+1] = temp;
flag = true;
}
}
}
return sortedArray;
}
option 1
echo $(cat testfile)
Option 2
tr ' ' '\n' < testfile
This works in all browsers including earlier IE versions.
var arr = [];
[].push.apply(arr, htmlCollection);

Vue by default ships with the v-html directive to show it, you bind it onto the element itself rather than using the normal moustache binding for string variables.
So for your specific example you would need:

<tr v-repeat="logs">
<td v-html="fail"></td>
<td v-html="type"></td>
<td v-html="description"></td>

Double is a wrapper class,
The Double class wraps a value of the primitive type double in an object. An object of type Double contains a single field whose type is double.
In addition, this class provides several methods for converting a double to a String and a String to a double, as well as other constants and methods useful when dealing with a double.
The double data type,
The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is 4.94065645841246544e-324d to 1.79769313486231570e+308d (positive or negative). For decimal values, this data type is generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.
Check each datatype with their ranges : Java's Primitive Data Types.
Important Note : If you'r thinking to use double for precise values, you need to re-think before using it. Java Traps: double

Pierre Vriens hopefully this makes more sense. this is an O(nlogn) solution.
The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.
Try using headers to do authentication:
import urllib2, base64
request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.b64encode('%s:%s' % (username, password))
request.add_header("Authorization", "Basic %s" % base64string)
result = urllib2.urlopen(request)
Had the same problem as you and found the solution from this thread: http://forums.shopify.com/categories/9/posts/27662
After inspecting an SSIS Package(due to a SQL Server executing commands really slow), that was set up in a client of ours about 5-4 years before the time of me writing this, I found out that there were the below tasks: 1) insert data from an XML file into a table called [Importbarcdes].
2) merge command on an another target table, using as source the above mentioned table.
3) "delete from [Importbarcodes]", to clear the table of the row that was inserted after the XML file was read by the task of the SSIS Package.
After a quick inspection all statements(SELECT, UPDATE, DELETE etc.) on the table ImportBarcodes that had only 1 row, took about 2 minutes to execute.
Extended Events showed a whole lot PAGEIOLATCH_EX wait notifications.
No indexes were present of the table and no triggers were registered.
Upon close inspection of the properties of the table, in the Storage Tab and under general section, the Data Space field showed more than 6 GIGABYTES of space allocated in pages.
What happened:
The query ran for a good portion of time each day for the last 4 years, inserting and deleting data in the table, leaving unused pagefiles behind with out freeing them up.
So, that was the main reason of the wait events that were captured by the Extended Events Session and the slowly executed commands upon the table.
Running ALTER TABLE ImportBarcodes REBUILD
fixed the issue freeing up all the unused space. TRUNCATE TABLE ImportBarcodes
did a similar thing, with the only difference of deleting all pagefiles and data.

You absolutely need to make a new tuple -- then you can rebind the name (or whatever reference[s]) from the old tuple to the new one. The +=
operator can help (if there was only one reference to the old tuple), e.g.:
thetup += ('1200.00',)
does the appending and rebinding in one fell swoop.
Here is a solution using the plyr
package.
The following line of code essentially tells ddply
to first group your data by Group, and then within each group returns a subset where the Score equals the maximum score in that group.
library(plyr)
ddply(data, .(Group), function(x)x[x$Score==max(x$Score), ])
Group Score Info
1 1 3 c
2 2 4 d
And, as @SachaEpskamp points out, this can be further simplified to:
ddply(df, .(Group), function(x)x[which.max(x$Score), ])
(which also has the advantage that which.max
will return multiple max lines, if there are any).
There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.
from urllib.request import urlopen
from socket import timeout
url = "http://......"
try:
string = urlopen(url, timeout=5).read()
except ConnectionResetError:
print("==> ConnectionResetError")
pass
except timeout:
print("==> Timeout")
pass

<b>
and <i>
are both related to style, whereas <em>
and <strong>
are semantic. In HTML 4, the first are classified as font style elements, and the latter as phrase elements.
As you indicated correctly, <i>
and <em>
are often considered similar, because browsers often render both in italics. But according to the specifications, <em>
indicates emphasis and <strong>
indicates stronger emphasis, which is quite clear, but often misinterpreted. On the other hand, the distinction between when to use <i>
or <b>
is really a matter of style.
This worked for me to return an array of strings from my config:

"Allow-Methods": [ "OPTIONS","GET","HEAD","POST","PUT","DELETE" ]
}
}

alert("First box must say 'JavaScript'!")
flag = false
}
if (Tester.line2.value!="Kit") {
alert("Second box must say 'Kit'!")
flag = false
}
if (flag) {
alert("Form is valid! Submitting form...")

One more code sample to showcase this:

{
int k = 0;
TestPlain(k);
Console.WriteLine("TestPlain:" + k);
TestRef(ref k);
Console.WriteLine("TestRef:" + k);
string t = "test";
TestObjPlain(t);
Console.WriteLine("TestObjPlain:" +t);
TestObjRef(ref t);
Console.WriteLine("TestObjRef:" + t);
}
public static void TestPlain(int i)
{
i = 5;
}
public static void TestRef(ref int i)
{
i = 5;
}
public static void TestObjPlain(string s)
{
s = "TestObjPlain";
}
public static void TestObjRef(ref string s)
{
s = "TestObjRef";
}
And the output:
TestPlain:0
TestRef:5
TestObjPlain:test
TestObjRef:TestObjRef
Browsers and OS's determine the style of the select boxes in most cases, and it's next to impossible to alter them with CSS alone. You'll have to look into replacement methods. The main trick is to apply appearance: none
which lets you override some of the styling.

It doesn't replace the OS select menu UI element so all the problems related to doing that are non-existant (not being able to break out of the browser window with a long list being the main one).
Good luck :)
A useful explanation to how braces are used (in addition to Filip Ekberg's useful answer, above) can be found in the short paper Parenthesis in Programming Languages.
I used a list in my controller class to set data into grid view. The code works fine for me:
public ActionResult ExpExcl()
{
List<PersonModel> person= new List<PersonModel>
{
new PersonModel() {FirstName= "Jenny", LastName="Mathew", Age= 23},
new PersonModel() {FirstName= "Paul", LastName="Meehan", Age=25}
};
var grid= new GridView();
grid.DataSource= person;
grid.DataBind();
Response.ClearContent();
Response.AddHeader("content-disposition","attachement; filename=data.xls");
Response.ContentType="application/excel";
StringWriter sw= new StringWriter();
HtmlTextWriter htw= new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View();
}
i had this issue before and the comments here helped in the past but this time it did not. i checked my proguard configuration and i removed the following lines and then it worked so proguard can have something to do with this error:
-optimizationpasses 5
-overloadaggressively
-repackageclasses ''
-allowaccessmodification
-dontskipnonpubliclibraryclassmembers
You can use VBScript, for example, file myscript.vbs
:
set wsobject = wscript.createobject("wscript.shell")
do while 1=1
wsobject.run "SnippingTool.exe",0,TRUE
wscript.sleep 3000
loop
Batch file:
cscript myscript.vbs %1
I tried with CSS, and or you need to use display: table or you need to use new css that is not yet supported on most browsers (2016).
So, I wrote a jquery plugin to do it for us, I am happy to share it:

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).
On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.
You can check awesome material design components for AngularJS:

MongoDB's ISODate() is just a helper function that wraps a JavaScript date object and makes it easier to work with ISO date strings.
You can still use all of the same methods as working with a normal JS Date, such as:
ISODate("2012-07-14T01:00:00+01:00").toLocaleTimeString()
// Note that getHours() and getMinutes() do not include leading 0s for single digit #s
ISODate("2012-07-14T01:00:00+01:00").getHours()
ISODate("2012-07-14T01:00:00+01:00").getMinutes()
Code :
var now = new Date();
var time = now.getTime();
time += 3600 * 1000;
now.setTime(time);
document.cookie =
'username=' + value +
'; expires=' + now.toUTCString() +
'; path=/';
There is a much simpler way. Put your picture in a comment box within the description cell. That way you only have one column and when you sort the picture will always stay with the description. Okay... Right click the cell containing the description... Insert comment...right click the outer border... Format comment...colours and lines tab... Colour drop down...Fill effects...Picture tab...select picture...browse for your picture (it might be best to keep all pictures in one folder for ease of placement)...ok... you will probably need to go to the size tab and frig around with the height and width. Done... You now only need to mouse over the red in the top right corner of the cell and the picture will appear...like magic.
This method means that the row height can be kept to a minimum and the pictures can be as big as you like.
I have solved this issue,
login to server computer where SQL Server is installed get you csv file on server computer and execute your query it will insert the records.
If you will give datatype compatibility issue change the datatype for that column
It may not be quite what you want, since it's not a standard command on anyone's systems, but since my program should work fine on POSIX systems (if compiled), I'll mention it anyway. If you have the ability to compile or add programs on the machine in question, it should work.
I've used it without issue for about a year now, but it could be that it won't handle some edge cases. Most specifically, I have no idea what it would do with newlines in strings; a case for \\n
might need to be added. This list of characters is not authoritative, but I believe it covers everything else.
I wrote this specifically as a 'helper' program so I could make a wrapper for things like scp
commands.
It can likely be implemented as a shell function as well
I therefore present escapify.c
. I use it like so:
scp user@host:"$(escapify "/this/path/needs to be escaped/file.c")" destination_file.c
PLEASE NOTE: I made this program for my own personal use. It also will (probably wrongly) assume that if it is given more than one argument that it should just print an unescaped space and continue on. This means that it can be used to pass multiple escaped arguments correctly, but could be seen as unwanted behavior by some.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
char c='\0';
int i=0;
int j=1;
/* do not care if no args passed; escaped nothing is still nothing. */
if(argc < 2)
{
return 0;
}
while(j<argc)
{
while(i<strlen(argv[j]))
{
c=argv[j][i];
/* this switch has no breaks on purpose. */
switch(c)
{
case ';':
case '\'':

}

/* newline at end */
putchar ('\n');
return 0;
}
You'll see people using the Timer class to do this. Unfortunately, it isn't always accurate. Your best bet is to get the system time when the user enters input, calculate a target system time, and check if the system time has exceeded the target system time. If it has, then break out of the loop.
Just to augment the accepted answer with a brief newbie-friendly short answer, you probably don't need exec
.
If you're still here, the following discussion should hopefully reveal why. When you run, say,
sh -c 'command'
you run a sh
instance, then start command
as a child of that sh
instance. When command
finishes, the sh
instance also finishes.
sh -c 'exec command'
runs a sh
instance, then replaces that sh
instance with the command
binary, and runs that instead.
Of course, both of these are useless in this limited context; you simply want
command
There are some fringe situations where you want the shell to read its configuration file or somehow otherwise set up the environment as a preparation for running command
. This is pretty much the sole situation where exec command
is useful.
#!/bin/sh
ENVIRONMENT=$(some complex task)
exec command
This does some stuff to prepare the environment so that it contains what is needed. Once that's done, the sh
instance is no longer necessary, and so it's a (minor) optimization to simply replace the sh
instance with the command
process, rather than have sh
run it as a child process and wait for it, then exit as soon as it finishes.
Similarly, if you want to free up as much resources as possible for a heavyish command at the end of a shell script, you might want to exec
that command as an optimization.
If something forces you to run sh
but you really wanted to run something else, exec something else
is of course a workaround to replace the undesired sh
instance (like for example if you really wanted to run your own spiffy gosh
instead of sh
but yours isn't listed in /etc/shells
so you can't specify it as your login shell).
The second use of exec
to manipulate file descriptors is a separate topic. The accepted answer covers that nicely; to keep this self-contained, I'll just defer to the manual for anything where exec
is followed by a redirect instead of a command name.
No there actually is no way to prevent a user from doing a particular task. But you can always take measures! The image sharing websites have a huge team of developers working day and night to create such an algorithm where you prevent user from saving the image files.
Try this:
$('img').mousedown(function (e) {
if(e.button == 2) { // right click
return false; // do nothing!
}
}
So the user won't be able to click on the Save Image As... option from the menu and in turn he won't get a chance to save the image.
Other way is to use background-image
. This way, the user won't be able to right click and Save the Image As... But he can still see the resources in the Inspector.
Even I am new to this one, few days ago I was surfing Flickr when I tried to right click, it did not let me do a thing. Which in turn was the first method that I provided you with. Then I tried to go and see the inspector, there I found nothing. Why? Since they were using background-image
and at the same time they were using data:imagesource
as its location.
Which was amazing for me too. You can precvent user from saving image files this way easily.
It is known as Data URI Scheme: http://en.wikipedia.org/wiki/Data_URI_scheme
Please remember brother, when you're letting a user surf your website you're giving him READ permissions on the server side so he can read all the files without any problem. The same is the issue with image files. He can read the image files, and then he can easily save them. He downloads the images on the first place when he is surfing your website. So there is not an issue for him to save them on his disk.
That also happened to me on a recreated directory, the directory is the same but to make it work again just run:
cd .
It seems that your
$(".modal").on('shown.bs.modal') // One way Or
You can do this in a slight different way, like this
$('.btn').click(function(){
// Send the src on click of button to the iframe. Which will make it load.
$(".openifrmahere").find('iframe').attr("src","http://www.hf-dev.info");
$('.modal').modal({show:true});
// Hide the loading message
$(".openifrmahere").find('iframe').load(function() {
$('.loading').hide();
});
})
Here is a basic implementation of writing and then reading json
file using json4s
.
import org.json4s._
import org.json4s.jackson.JsonMethods._
import org.json4s.JsonDSL._
import java.io._
import scala.io.Source
object MyObject { def main(args: Array[String]) {
val myMap = Map("a" -> List(3,4), "b" -> List(7,8))
// writing a file
val jsonString = pretty(render(myMap))
val pw = new PrintWriter(new File("my_json.json"))
pw.write(jsonString)
pw.close()
// reading a file
val myString = Source.fromFile("my_json.json").mkString
println(myString)
val myJSON = parse(myString)
println(myJSON)
// Converting from JOjbect to plain object
implicit val formats = DefaultFormats
val myOldMap = myJSON.extract[Map[String, List[Int]]]
println(myOldMap)
}
}
The real rule is: Don't throw away exceptions. The objectivity of the author of your quote is questionable, as evidenced by the fact that it ends with
or I will stab you
Of course, be aware that signals (by default) throw exceptions, and normally long-running processes are terminated through a signal, so catching Exception and not terminating on signal exceptions will make your program very hard to stop. So don't do this:
#! /usr/bin/ruby
while true do
begin
line = STDIN.gets
# heavy processing
rescue Exception => e
puts "caught exception #{e}! ohnoes!"
end
end
No, really, don't do it. Don't even run that to see if it works.
However, say you have a threaded server and you want all exceptions to not:
thread.abort_on_exception = true
). Then this is perfectly acceptable in your connection handling thread:
begin
# do stuff
rescue Exception => e
myLogger.error("uncaught #{e} exception while handling connection: #{e.message}")
myLogger.error("Stack trace: #{backtrace.map {|l| " #{l}\n"}.join}")
end
The above works out to a variation of Ruby's default exception handler, with the advantage that it doesn't also kill your program. Rails does this in its request handler.
Signal exceptions are raised in the main thread. Background threads won't get them, so there is no point in trying to catch them there.
This is particularly useful in a production environment, where you do not want your program to simply stop whenever something goes wrong. Then you can take the stack dumps in your logs and add to your code to deal with specific exception further down the call chain and in a more graceful manner.
Note also that there is another Ruby idiom which has much the same effect:
a = do_something rescue "something else"
In this line, if do_something
raises an exception, it is caught by Ruby, thrown away, and a
is assigned "something else"
.
Generally, don't do that, except in special cases where you know you don't need to worry. One example:
debugger rescue nil
The debugger
function is a rather nice way to set a breakpoint in your code, but if running outside a debugger, and Rails, it raises an exception. Now theoretically you shouldn't be leaving debug code lying around in your program (pff! nobody does that!) but you might want to keep it there for a while for some reason, but not continually run your debugger.
Note:
If you've run someone else's program that catches signal exceptions and ignores them, (say the code above) then:
pgrep ruby
, or ps | grep ruby
, look for your offending program's PID, and then run kill -9 <PID>
. If you are working with someone else's program which is, for whatever reason, peppered with these ignore-exception blocks, then putting this at the top of the mainline is one possible cop-out:
%W/INT QUIT TERM/.each { |sig| trap sig,"SYSTEM_DEFAULT" }
This causes the program to respond to the normal termination signals by immediately terminating, bypassing exception handlers, with no cleanup. So it could cause data loss or similar. Be careful!
If you need to do this:
begin
do_something
rescue Exception => e
critical_cleanup
raise
end
you can actually do this:
begin
do_something
ensure
critical_cleanup
end
In the second case, critical cleanup
will be called every time, whether or not an exception is thrown.
Look into android.util.Log
. It lets you write to the log with various log levels, and you can specify different tags to group the output.
For example
Log.w("myApp", "no network");
will output a warning with the tag myApp and the message no network.
You solve the issue with a try/ catch. This crash happens when user close the app before the start intent.
try
{
Intent mIntent = new Intent(getActivity(),MusicHome.class);
mIntent.putExtra("SigninFragment.user_details", bundle);
startActivity(mIntent);
}
catch (Exception e) {
e.printStackTrace();
}
Most layout managers work best with a component's preferredSize, and most GUI's are best off allowing the components they contain to set their own preferredSizes based on their content or properties. To use these layout managers to their best advantage, do call pack()
on your top level containers such as your JFrames before making them visible as this will tell these managers to do their actions -- to layout their components.
Often when I've needed to play a more direct role in setting the size of one of my components, I'll override getPreferredSize and have it return a Dimension that is larger than the super.preferredSize (or if not then it returns the super's value).
For example, here's a small drag-a-rectangle app that I created for another question on this site:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MoveRect extends JPanel {
private static final int RECT_W = 90;
private static final int RECT_H = 70;
private static final int PREF_W = 600;
private static final int PREF_H = 300;
private static final Color DRAW_RECT_COLOR = Color.black;
private static final Color DRAG_RECT_COLOR = new Color(180, 200, 255);
private Rectangle rect = new Rectangle(25, 25, RECT_W, RECT_H);
private boolean dragging = false;
private int deltaX = 0;
private int deltaY = 0;
public MoveRect() {
MyMouseAdapter myMouseAdapter = new MyMouseAdapter();
addMouseListener(myMouseAdapter);
addMouseMotionListener(myMouseAdapter);
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
if (rect != null) {
Color c = dragging ? DRAG_RECT_COLOR : DRAW_RECT_COLOR;
g.setColor(c);
Graphics2D g2 = (Graphics2D) g;
g2.draw(rect);
}
}
@Override
public Dimension getPreferredSize() {
return new Dimension(PREF_W, PREF_H);
}
private class MyMouseAdapter extends MouseAdapter {
@Override
public void mousePressed(MouseEvent e) {
Point mousePoint = e.getPoint();
if (rect.contains(mousePoint)) {
dragging = true;
deltaX = rect.x - mousePoint.x;
deltaY = rect.y - mousePoint.y;
}
}
@Override
public void mouseReleased(MouseEvent e) {
dragging = false;
repaint();
}
@Override
public void mouseDragged(MouseEvent e) {
Point p2 = e.getPoint();
if (dragging) {
int x = p2.x + deltaX;
int y = p2.y + deltaY;
rect = new Rectangle(x, y, RECT_W, RECT_H);
MoveRect.this.repaint();
}
}
}
private static void createAndShowGui() {
MoveRect mainPanel = new MoveRect();
JFrame frame = new JFrame("MoveRect");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(mainPanel);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
Note that my main class is a JPanel, and that I override JPanel's getPreferredSize:
public class MoveRect extends JPanel {
//.... deleted constants
private static final int PREF_W = 600;
private static final int PREF_H = 300;
//.... deleted fields and constants
//... deleted methods and constructors
@Override
public Dimension getPreferredSize() {
return new Dimension(PREF_W, PREF_H);
}
Also note that when I display my GUI, I place it into a JFrame, call pack();
on the JFrame, set its position, and then call setVisible(true);
on my JFrame:
private static void createAndShowGui() {
MoveRect mainPanel = new MoveRect();
JFrame frame = new JFrame("MoveRect");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(mainPanel);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
You can try the Boost Tokenizer library, in particular the Escaped List Separator
Perhaps this is easier to read:
a2.all? { |e| a1.include?(e) }
You can also use array intersection:
(a1 & a2).size == a1.size
Note that size
is used here just for speed, you can also do (slower):
(a1 & a2) == a1
But I guess the first is more readable. These 3 are plain ruby (not rails).
awk '{$1=$2=$3=""}1' file
NB: this method will leave "blanks" in 1,2,3 fields but not a problem if you just want to look at output.
It basically is higher/greater in everything else. A keyboard is less of a priority than the real time process. This means the process will be taken into account faster then keyboard and if it can't handle that, then your keyboard is slowed.
To run the functions in a DLL, first find out what those functions are using any PE (Portable Executable) analysis program (e.g. Dependency Walker). Then use RUNDLL32.EXE with this syntax:
RUNDLL32.EXE <dllname>,<entrypoint> <optional arguments>
dllname is the path and name of your dll file, entrypoint is the function name, and optional arguments are the function arguments
All you need to do is reverse your ORDER BY
. Add or remove DESC
to it.
if your exe happens to be a console app, you might be interested in reading the stdout and stderr -- for that, I'll humbly refer you to this example:

If you only have as "click event handler", use a <button>
instead. A link has a specific semantic meaning.
E.g.:
<button onclick="ShowOld(2367,146986,2)">
<img title="next page" alt="next page" src="/themes/me/img/arrn.png">
</button>
If the file size is not big, then it is faster to read the entire file and split it afterwards
var filestreams = sr.ReadToEnd().Split(Environment.NewLine,
StringSplitOptions.RemoveEmptyEntries);
Was facing this issue, Solved by adding package-info in my package
and the following code in it:
@XmlSchema(
namespace = "http://www.w3schools.com/xml/",
elementFormDefault = XmlNsForm.QUALIFIED,
xmlns = {
@XmlNs(prefix="", namespaceURI="http://www.w3schools.com/xml/")
}
)
package com.gateway.ws.outbound.bean;
import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
To me, the following is more readable (thus preferable) way to do it:
git reset HEAD~1
Instead of 1
, there could be any number of commits you want to unstage.
I have tried all the solutions and this one worked for me
let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options:
.ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)
yourImage.image = decodedimage
I am using this.
s = s.replaceAll("\\W", "");
It replace all special characters from string.
Here
\w : A word character, short for [a-zA-Z_0-9]
\W : A non-word character
Create a class like this:
public class Data
{
public string Id {get; set;}
public string Name {get; set;}
public string First_Name {get; set;}
public string Last_Name {get; set;}
public string Username {get; set;}
public string Gender {get; set;}
public string Locale {get; set;}
}
(I'm not 100% sure, but if that doesn't work you'll need use [DataContract]
and [DataMember]
for DataContractJsonSerializer
.)
Then create JSonSerializer
:
private static readonly XmlObjectSerializer Serializer = new DataContractJsonSerializer(typeof(Data));
and deserialize object:
// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
using(var stream = new MemoryStream(byteArray))
{
(Data)Serializer.ReadObject(stream);
}
To add to Jason Bunting's answer, if you're using nodejs or something (and this works in dom js, too), you could use this
instead of window

this['fun'+'ctionName']();
That is a problem of security protocol. I am using TLSv1 but the host accept only TLSv1.1 and TLSv1.2 then I changed the protocol in Java with the instruction below:
System.setProperty("https.protocols", "TLSv1.1")
;
Session is used for maintaining a dialogue between server and user. It is more secure because it is stored on the server, we cannot easily access it. It embeds cookies on the user computer. It stores unlimited data.
Cookies are stored on the local computer. Basically, it maintains user identification, meaning it tracks visitors record. It is less secure than session. It stores limited amount of data, and is maintained for a limited time.
This may help someone with the same problem.

First thing, at the time the question was asked, uintptr_t
was not in C++. It's in C99, in <stdint.h>
, as an optional type. Many C++03 compilers do provide that file. It's also in C++11, in <cstdint>
, where again it is optional, and which refers to C99 for the definition.
In C99, it is defined as "an unsigned integer type with the property that any valid pointer to void can be converted to this type, then converted back to pointer to void, and the result will compare equal to the original pointer".
Take this to mean what it says. It doesn't say anything about size.
uintptr_t
might be the same size as a void*
. It might be larger. It could conceivably be smaller, although such a C++ implementation approaches perverse. For example on some hypothetical platform where void*
is 32 bits, but only 24 bits of virtual address space are used, you could have a 24-bit uintptr_t
which satisfies the requirement. I don't know why an implementation would do that, but the standard permits it.

If you do not have Administrator access to the MySQL Server configuration (i.e. you are using a hosting service), then there are 2 options to get this to work:
1) Request that the old_passwords option be set to false on the MySQL server
2) Downgrade PHP to 5.2.2 until option 1 occurs.
From what I've been able to find, the issue seems to be with how the MySQL account passwords are stored and if the 'old_passwords' setting is set to true. This causes a compatibility issue between MySQL and newer versions of PHP (5.3+) where PHP attempts to connect using a 41-character hash but the MySQL server is still storing account passwords using a 16-character hash.
This incompatibility was brought about by the changing of the hashing method used in MySQL 4.1 which allows for both short and long hash lengths (Scenario 2 on this page from the MySQL site: http://dev.mysql.com/doc/refman/5.5/en/password-hashing.html) and the inclusion of the MySQL Native Driver in PHP 5.3 (backwards compatibility issue documented on bullet 7 of this page from the PHP documentation: http://www.php.net/manual/en/migration53.incompatible.php).

__del__()
gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.__init__()
raises an exception then the object is assumed to be incomplete and __del__()
won't be invoked.Edit: Use printf("val = 0x%" PRIx64 "\n", val);
instead.
Try printf("val = 0x%llx\n", val);
. See the printf manpage:
ll (ell-ell). A following integer conversion corresponds to a long long int or unsigned long long int argument, or a following n conversion corresponds to a pointer to a long long int argument.
Edit: Even better is what @M_Oehm wrote: There is a specific macro for that, because unit64_t
is not always a unsigned long long
: PRIx64

If you already know beforehand how many columns your new DataTable would have, you can do something like this:
DataTable matrix = ... // get matrix values from db
DataTable newDataTable = new DataTable();
newDataTable.Columns.Add("c_to", typeof(string));
newDataTable.Columns.Add("p_to", typeof(string));
var query = from r in matrix.AsEnumerable()
where r.Field<string>("c_to") == "foo" &&
r.Field<string>("p_to") == "bar"
let objectArray = new object[]
{
r.Field<string>("c_to"), r.Field<string>("p_to")
}
select objectArray;
foreach (var array in query)
{
newDataTable.Rows.Add(array);
}

It is failing as cURL is unable to verify the certificate provided by the server.
There are two options to get this to work:
Use cURL with -k
option which allows curl to make insecure connections, that is cURL does not verify the certificate.
Add the root CA (the CA signing the server certificate) to /etc/ssl/certs/ca-certificates.crt
You should use option 2 as it's the option that ensures that you are connecting to secure FTP server.

This is my edited version : you just need to add an extra argument "autoClose".
example :
$('input[name="fieldName"]').datepicker({ autoClose: true});
also you can specify a close callback if you want. :)
replace datepicker.js with this:
!function( $ ) {
// Picker object
var Datepicker = function(element, options , closeCallBack){
this.element = $(element);
this.format = DPGlobal.parseFormat(options.format||this.element.data('date-format')||'dd/mm/yyyy');
this.autoClose = options.autoClose||this.element.data('date-autoClose')|| true;
this.closeCallback = closeCallBack || function(){};
this.picker = $(DPGlobal.template)
.appendTo('body')
.on({
click: $.proxy(this.click, this)//,
//mousedown: $.proxy(this.mousedown, this)

this.isInput = this.element.is('input');
this.component = this.element.is('.date') ? this.element.find('.add-on') : false;
if (this.isInput) {
this.element.on({
focus: $.proxy(this.show, this),
//blur: $.proxy(this.hide, this),
keyup: $.proxy(this.update, this)
});
} else {

this.component.on('click', $.proxy(this.show, this));

You might find it best to change that to ~/.bash_profile

Just type javac
. If it is installed you get usage information, otherwise it would just ask if you would like to install Java.
In my case I have a spring boot application which is kind of mixing spring and jaxrs. So I have a java class which inherits from the class org.glassfish.jersey.server.ResourceConfig
. I had to add this line to the constructor of that class so that the spring endpoints are still called: property(ServletProperties.FILTER_FORWARD_ON_404, true)
.
If style and format are going to be part of your reviews, there should be an agreed upon style guide to measure against. If there is one, do what the style guide says. If there's not one, details like this should be left as they are written. It's a waste of time and energy, and distracts from what code reviews really ought to be uncovering. Seriously, without a style guide I would push to NOT change code like this as a matter of principle, even when it doesn't use the convention I prefer.
And not that it matters, but my personal preference is if (ptr)
. The meaning is more immediately obvious to me than even if (ptr == NULL)
.
Maybe he's trying to say that it's better to handle error conditions before the happy path? In that case I still don't agree with the reviewer. I don't know that there's an accepted convention for this, but in my opinion the most "normal" condition ought to come first in any if statement. That way I've got less digging to do to figure out what the function is all about and how it works.
The exception to this is if the error causes me to bail from the function, or I can recover from it before moving on. In those cases, I do handle the error first:
if (error_condition)
bail_or_fix();
return if not fixed;
// If I'm still here, I'm on the happy path
By dealing with the unusual condition up front, I can take care of it and then forget about it. But if I can't get back on the happy path by handling it up front, then it should be handled after the main case because it makes the code more understandable. In my opinion.
But if it's not in a style guide then it's just my opinion, and your opinion is just as valid. Either standardize or don't. Don't let a reviewer pseudo-standardize just because he's got an opinion.
When creating the chart object you need to save the instance in a variable.
var currentChart = new Chart(ctx, ...);
And before loading new data, you need to destroy it:
currentChart.destroy();
Create a group object and call methods like below example:
grp = df.groupby(['col1', 'col2', 'col3'])
grp.max()
grp.mean()
grp.describe()
I've just encountered a bit different but similar situation. Not 100% sure if it'd be a resolution to your case, but I resolved the issue for Django 1.3 by setting a POST parameter 'csrfmiddlewaretoken' with the proper cookie value string which is usually returned within the form of your home HTML by Django's template system with '{% csrf_token %}' tag. I did not try on the older Django, just happened and resolved on Django1.3. My problem was that the first request submitted via Ajax from a form was successfully done but the second attempt from the exact same from failed, resulted in 403 state even though the header 'X-CSRFToken' is correctly placed with the CSRF token value as well as in the case of the first attempt. Hope this helps.

The parentheses capture particular strings for use by the backslashed numbers.
You can use JOIN syntax in FROM clause in DELETE in SQL Server but you still delete from first table only and it's proprietary Transact-SQL extension which is alternative to sub-query.
From example here:
-- Transact-SQL extension
DELETE
FROM Sales.SalesPersonQuotaHistory
FROM Sales.SalesPersonQuotaHistory AS spqh INNER JOIN
Sales.SalesPerson AS sp ON spqh.BusinessEntityID = sp.BusinessEntityID
WHERE sp.SalesYTD > 2500000.00;
Can also use the following code to check the nginx status:
sudo /etc/init.d/nginx status
I would do this in CSS:
div.centered {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
then in HTML:
<div class="centered"></div>
If you want to use the destructuring assignment, you'll need the same number of floats as you have variables:
grade_1, grade_2, grade_3, average = 0.0, 0.0, 0.0, 0.0
If you want the latest file in the directory and you are using only the LastWriteTime
to determine the latest file, you can do something like below:
gci path | sort LastWriteTime | select -last 1
On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar
gci path | select -last 1
Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}
The problem is with the following CSS line on .nav_button
:
margin: 0 auto;
That would only work if you had one button, that's why they're off-centered when there are more than one nav_button
divs.
If you want all your buttons centered nest the nav_buttons
in another div:
<div class="nav">
<div class="centerButtons">
<div class="nav_button">
<div class="b_left"></div>
<div class="b_middle">Home</div>
<div class="b_right"></div>
</div>
<div class="nav_button">
<div class="b_left"></div>
<div class="b_middle">Contact Us</div>
<div class="b_right"></div>
</div>
</div>
</div>
And style it this way:
.nav{
margin-top:167px;
width:1024px;
height:34px;
}
/* Centers the div that nests the nav_buttons */
.centerButtons {
margin: 0 auto;
float: left;
}
.nav_button{
height:34px;
margin-right:10px;
float: left;
}
The easiest way that I found to fix this is to uninstall everything then install a specific version of tensorflow-gpu:
pip uninstall tensorflow
pip uninstall tensorflow-gpu
pip install tensorflow-gpu==2.0.0
pip install tensorflow_hub
pip install tensorflow_datasets
You can check if this worked by adding the following code into a python file:
from __future__ import absolute_import, division, print_function, unicode_literals
import numpy as np
import tensorflow as tf
import tensorflow_hub as hub
import tensorflow_datasets as tfds
print("Version: ", tf.__version__)
print("Eager mode: ", tf.executing_eagerly())
print("Hub Version: ", hub.__version__)
print("GPU is", "available" if tf.config.experimental.list_physical_devices("GPU") else "NOT AVAILABLE")
Run the file and then the output should be something like this:
Version: 2.0.0
Eager mode: True
Hub Version: 0.7.0
GPU is available
Hope this helps
This gets parent if it is a div. Then it gets class.
var div = $(this).parent("div");
var _class = div.attr("class");
system("COLOR 0A");
'
where 0A is a combination of background and font color 0
To print a specific row we have couple of pandas method
loc
- It only get label i.e column name or Featuresiloc
- Here i stands for integer, actually row number ix
- It is a mix of label as well as integerHow to use for specific row
loc
df.loc[row,column]
For first row and all column
df.loc[0,:]
For first row and some specific column
df.loc[0,'column_name']
iloc
For first row and all column
df.iloc[0,:]
For first row and some specific column i.e first three cols
df.iloc[0,0:3]
try this:
ren "File 1-1" "File 1 - %date:/=-% %time::=-%"
I know this is an old post, but a good time to use PrimaryKeyColumn
would be if you wanted a unidirectional relationship or had multiple tables all sharing the same id.
In general this is a bad idea and it would be better to use foreign key relationships with JoinColumn
.
Having said that, if you are working on an older database that used a system like this then that would be a good time to use it.
If the list to compare against is large, (ie the manilaListRange range in the example above), it is a smart move to use the match function. It avoids the use of a loop which could slow down the procedure. If you can ensure that the manilaListRange is all upper or lower case then this seems to be the best option to me. It is quick to apply 'UCase' or 'LCase' as you do your match.
If you did not have control over the ManilaListRange then you might have to resort to looping through this range in which case there are many ways to compare 'search', 'Instr', 'replace' etc.
You are doing everything right, except passing your bundle path to asset()
function.
According to documentation - in your example this should look like below:
{{ asset('bundles/webshome/css/main.css') }}
Tip: you also can call assets:install with --symlink
key, so it will create symlinks in web folder. This is extremely useful when you often apply js
or css
changes (in this way your changes, applied to src/YouBundle/Resources/public
will be immediately reflected in web
folder without need to call assets:install
again):
app/console assets:install web --symlink
Also, if you wish to add some assets in your child template, you could call parent()
method for the Twig block. In your case it would be like this:
{% block stylesheets %}
{{ parent() }}
<link href="{{ asset('bundles/webshome/css/main.css') }}" rel="stylesheet">
{% endblock %}
simplexml_load_file()
interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed
is a string.
You have two options:
Use file_get_contents()
to get the XML feed as a string, and use e simplexml_load_string()
:
$feed = file_get_contents('...');
$items = simplexml_load_string($feed);
Load the XML feed directly using simplexml_load_file()
:
$items = simplexml_load_file('...');
It might be the Unmerged paths that cause
error: Merging is not possible because you have unmerged files.
If so, try:
git status
if it says
You have unmerged paths.
do as suggested: either resolve conflicts and then commit or abort the merge entirely with
git merge --abort
You might also see files listed under Unmerged paths, which you can resolve by doing
git rm <file>
Date and time input is accepted in almost any reasonable format, including ISO 8601, SQL-compatible, traditional POSTGRES, and others. For some formats, ordering of month, day, and year in date input is ambiguous and there is support for specifying the expected ordering of these fields.
In other words: just write anything and it will work.
Or check this table with all the unambiguous formats.
One simple method is to use place
to use an image as a background image. This is the type of thing that place
is really good at doing.
For example:
background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)
You can then grid
or pack
other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.
Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:
background_label.image = background_image
You need formulas to convert latitude and longitude to rectangular coordinates. There are a great number to choose from and each will distort the map in a different way. Wolfram MathWorld has a good collection:

Follow the "See Also" links.
Just so you can find it next time, here is how you search for the enumerable Linq extensions. The methods are static methods of Enumerable, thus Enumerable.Any, Enumerable.Where and Enumerable.Exists.
As the third returns no usable result, I found that you meant List.Exists, thus:
I also recommend hookedonlinq.com as this is has very comprehensive and clear guides, as well clear explanations of the behavior of Linq methods in relation to deferness and lazyness.
Hope it will help someone someday. I was making a small POC and came across this. A button, onClick display contents of the folder. Below is the HTML,
<input type=button onClick="parent.location='file:///C:/Users/' " value='Users'>
There is indentation problem. The code below will work:
import textwrap
def sendMail(FROM,TO,SUBJECT,TEXT,SERVER):
import smtplib
"""this is some test documentation in the function"""
message = textwrap.dedent("""\
From: %s
To: %s
Subject: %s
%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT))
# Send the mail
server = smtplib.SMTP(SERVER)
server.sendmail(FROM, TO, message)
server.quit()
If you want highlight several patterns with different colors see this bash script.
Basic usage:
echo warn error debug info 10 nil | colog
You can change patterns and colors while running pressing one key and then enter key.
I use
patch -p1 --merge < patchfile
This way, conflicts may be resolved as usual.
Do you want something like the given fiddle!
HTML
<div class="button">
<input type="button" value="TELL ME MORE" onClick="document.location.reload(true)">
</div>
CSS
.button input[type="button"] {
color:#08233e;

}
If you are not on the same network you could use this third party tool called localtunnel
It basically routes your content through another server and you access that.
Arrays inherit equals()
from Object
and hence compare only returns true if comparing an array against itself.
On the other hand, Arrays.equals
compares the elements of the arrays.
This snippet elucidates the difference:
Object o1 = new Object();
Object o2 = new Object();
Object[] a1 = { o1, o2 };
Object[] a2 = { o1, o2 };
System.out.println(a1.equals(a2)); // prints false
System.out.println(Arrays.equals(a1, a2)); // prints true
See also Arrays.equals()
. Another static method there may also be of interest: Arrays.deepEquals()
.
Use position: fixed
on the div
that contains your header, with something like
#header {
position: fixed;
}
#content {
margin-top: 100px;
}
In this example, when #content
starts off 100px below #header
, but as the user scrolls, #header
stays in place. Of course it goes without saying that you'll want to make sure #header
has a background so that its content will actually be visible when the two div
s overlap. Have a look at the position
property here: http://reference.sitepoint.com/css/position
You want to use:
git checkout --ours foo/bar.java
git add foo/bar.java
If you rebase a branch feature_x
against main
(i.e. running git rebase main
while on branch feature_x
), during rebasing ours
refers to main
and theirs
to feature_x
.
As pointed out in the git-rebase docs:
Note that a rebase merge works by replaying each commit from the working branch on top of the branch. Because of this, when a merge conflict happens, the side reported as ours is the so-far rebased series, starting with <upstream>, and theirs is the working branch. In other words, the sides are swapped.
For further details read this thread.
you can do it with filter query q=*:*&fq=-id:*
let its required n bit then 2^n=(base)^digit and then take log and count no. for n
Assuming input[row][col],
rows = len(input)
cols = map(len, input) #list of column lengths
try this :)
function getDefaultDate(){
var now = new Date();
var day = ("0" + now.getDate()).slice(-2);
var month = ("0" + (now.getMonth() + 1)).slice(-2);
var today = now.getFullYear()+"-"+(month)+"-"+(day) ;
return today;
}
$(document).ready(function(){
$("#dateid").val( getDefaultDate());
});
No, CASE
is a function, and can only return a single value. I think you are going to have to duplicate your CASE logic.
The other option would be to wrap the whole query with an IF and have two separate queries to return results. Without seeing the rest of the query, it's hard to say if that would work for you.
The capitalization is wrong, and you have an extra argument.
Do this instead:
$('img#thumb').removeAttr('id');
For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.
From other answers here, I was kind of confused with how git rebase -i
could be used to remove a commit, so I hope it's OK to jot down my test case here (very similar to the OP).
Here is a bash
script that you can paste in to create a test repository in the /tmp
folder:
set -x
rm -rf /tmp/myrepo*
cd /tmp
mkdir myrepo_git
cd myrepo_git
git init
git config user.name me
git config user.email [email protected]
mkdir folder
echo aaaa >> folder/file.txt
git add folder/file.txt
git commit -m "1st git commit"
echo bbbb >> folder/file.txt
git add folder/file.txt
git commit -m "2nd git commit"
echo cccc >> folder/file.txt
git add folder/file.txt
git commit -m "3rd git commit"
echo dddd >> folder/file.txt
git add folder/file.txt
git commit -m "4th git commit"
echo eeee >> folder/file.txt
git add folder/file.txt
git commit -m "5th git commit"
At this point, we have a file.txt
with these contents:
aaaa
bbbb
cccc
dddd
eeee
At this point, HEAD is at the 5th commit, HEAD~1 would be the 4th - and HEAD~4 would be the 1st commit (so HEAD~5 wouldn't exist). Let's say we want to remove the 3rd commit - we can issue this command in the myrepo_git
directory:
git rebase -i HEAD~4
(Note that git rebase -i HEAD~5
results with "fatal: Needed a single revision; invalid upstream HEAD~5".) A text editor (see screenshot in @Dennis' answer) will open with these contents:
pick 5978582 2nd git commit
pick 448c212 3rd git commit
pick b50213c 4th git commit
pick a9c8fa1 5th git commit
# Rebase b916e7f..a9c8fa1 onto b916e7f
# ...
So we get all commits since (but not including) our requested HEAD~4. Delete the line pick 448c212 3rd git commit
and save the file; you'll get this response from git rebase
:
error: could not apply b50213c... 4th git commit
When you have resolved this problem run "git rebase --continue".
If you would prefer to skip this patch, instead run "git rebase --skip".
To check out the original branch and stop rebasing run "git rebase --abort".
Could not apply b50213c... 4th git commit
At this point open myrepo_git/folder/file.txt
in a text editor; you'll see it has been modified:
aaaa
bbbb
<<<<<<< HEAD
=======
cccc
dddd
>>>>>>> b50213c... 4th git commit
Basically, git
sees that when HEAD got to 2nd commit, there was content of aaaa
+ bbbb
; and then it has a patch of added cccc
+dddd
which it doesn't know how to append to the existing content.
So here git
cannot decide for you - it is you who has to make a decision: by removing the 3rd commit, you either keep the changes introduced by it (here, the line cccc
) -- or you don't. If you don't, simply remove the extra lines - including the cccc
- in folder/file.txt
using a text editor, so it looks like this:
aaaa
bbbb
dddd
... and then save folder/file.txt
. Now you can issue the following commands in myrepo_git
directory:
$ nano folder/file.txt # text editor - edit, save
$ git rebase --continue
folder/file.txt: needs merge
You must edit all merge conflicts and then
mark them as resolved using git add
Ah - so in order to mark that we've solved the conflict, we must git add
the folder/file.txt
, before doing git rebase --continue
:
$ git add folder/file.txt
$ git rebase --continue
Here a text editor opens again, showing the line 4th git commit
- here we have a chance to change the commit message (which in this case could be meaningfully changed to 4th (and removed 3rd) commit
or similar). Let's say you don't want to - so just exit the text editor without saving; once you do that, you'll get:
$ git rebase --continue
[detached HEAD b8275fc] 4th git commit
1 file changed, 1 insertion(+)
Successfully rebased and updated refs/heads/master.
At this point, now you have a history like this (which you could also inspect with say gitk .
or other tools) of the contents of folder/file.txt
(with, apparently, unchanged timestamps of the original commits):
1st git commit | +aaaa
----------------------------------------------
2nd git commit | aaaa
| +bbbb
----------------------------------------------
4th git commit | aaaa
| bbbb
| +dddd
----------------------------------------------
5th git commit | aaaa
| bbbb
| dddd
| +eeee
And if previously, we decided to keep the line cccc
(the contents of the 3rd git commit that we removed), we would have had:
1st git commit | +aaaa
----------------------------------------------
2nd git commit | aaaa
| +bbbb
----------------------------------------------
4th git commit | aaaa
| bbbb
| +cccc
| +dddd
----------------------------------------------
5th git commit | aaaa
| bbbb
| cccc
| dddd
| +eeee
Well, this was the kind of reading I hoped I'd have found, to start grokking how git rebase
works in terms of deleting commits/revisions; so hope it might help others too...
To produce the same results:
MessageDigest sha1 = MessageDigest.getInstance("SHA1", BOUNCY_CASTLE_PROVIDER);
byte[] digest = sha1.digest(content);

By using correct indentation. Python is whitespace aware, so you need to follow its indentation guidlines for blocks or you'll get indentation errors.
Are you calling the web service from client script or on the server side?
You may find sending a content type header to the server will help, e.g.
'application/json; charset=utf-8'
On the client side, I use prototype client side library and there is a contentType parameter when making an Ajax call where you can specify this. I think jQuery has a getJSON method.
I'm not sure whether it's a fix, or just another workaround, but uninstalling the application from my device helped. I'm still not sure what caused it, but @MrRogers answer helped me figure it out.
