Updated on Nov 24, 2016: Elasticsearch 5 apparently has changed the way to configure the JVM. See this answer here. The answer below still applies to versions < 5.
tirdadc, thank you for pointing this out in your comment below.
I have a pastebin page that I share with others when wondering about memory and ES. It's worked OK for me: http://pastebin.com/mNUGQCLY. I'll paste the contents here as well:

Edit the following files to modify memory and file number limits. These instructions assume Ubuntu 10.04, may work on later versions and other distributions/OSes. (Edit: This works for Ubuntu 14.04 as well.)

As Suhel Meman said in the comments:
SELECT column1, column2, column3 FROM table 1
UNION
SELECT column1, column2, column3 FROM table 2
...
would work.
But all your SELECTS
would have to consist of the same amount of columns. And because you are displaying it in one resulting table they should contain the same information.
What you might want to do, is a JOIN on Product ID or something like that. This way you would get more columns, which makes more sense most of the time.
You can't clone it, and how you are going to solve your problem depends on what the source of the data is.
One solution is to read all data from the InputStream into a byte array, and then create a ByteArrayInputStream around that byte array, and pass that input stream into your method.
Edit 1: That is, if the other method also needs to read the same data. I.e you want to "reset" the stream.
If you simply call interrupt()
, the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted()
is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is
Thread.currentThread().stop();
Method is deprecated, however.
Calling return
only returns from the current method. This only terminates the thread if you're at its top level.
Nevertheless, you should work with interrupt()
and build your code around it.
This is how I write my AsyncTask
the key point is add Thread.sleep(1);
@Override protected Integer doInBackground(String... params) {
Log.d(TAG, PRE + "url:" + params[0]);
Log.d(TAG, PRE + "file name:" + params[1]);
downloadPath = params[1];
int returnCode = SUCCESS;
FileOutputStream fos = null;
try {
URL url = new URL(params[0]);
File file = new File(params[1]);
fos = new FileOutputStream(file);
long startTime = System.currentTimeMillis();
URLConnection ucon = url.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
byte[] data = new byte[10240];
int nFinishSize = 0;
while( bis.read(data, 0, 10240) != -1){
fos.write(data, 0, 10240);
nFinishSize += 10240;
**Thread.sleep( 1 ); // this make cancel method work**
this.publishProgress(nFinishSize);
}
data = null;
Log.d(TAG, "download ready in"

} catch (IOException e) {

} catch (Exception e){
e.printStackTrace();
} finally{

You can pass data from PHP to javascript but the only way to get data from javascript to PHP is via AJAX.
The reason for that is you can build a valid javascript through PHP but to get data to PHP you will need to get PHP running again, and since PHP only runs to process the output, you will need a page reload or an asynchronous query.
You can use sum
to sum the elements of a list, however if your list is coming from raw_input
, you probably want to convert the items to int
or float
first:
l = raw_input().split(' ')
sum(map(int, l))
Although probably not the best method you could add:
#div1 {
...
font-size:0;
}
Executive summary / TL;DR:
Try doing a find & replace of "=" with "=". Yes, replace the equals sign with itself. For my scenario, it forced everything to update.
Background:
I frequently make formulas across multiple columns then concatenate them together. After doing such, I'll copy & paste them as values to extract my created formula. After this process, they're typically stuck displaying a formula, and not displaying a value, unless I enter the cell and press Enter. Pressing F2 & Enter repeatedly is not fun.
Follow these steps:
Add path to gitignore
file
Run this command
git rm -r --cached foldername
commit changes as usually.
According to official documentation, the following command worked for me.

This can be an issue with Glide. Use this while you are trying to load to many images and some of them are very large:
Glide.load("your image path")
.transform(
new MultiTransformation<>(
new CenterCrop(),
new RoundedCorners(
holder.imgCompanyLogo.getResources()
.getDimensionPixelSize(R.dimen._2sdp)
)
)
)
.error(R.drawable.ic_nfs_default)
.into(holder.imgCompanyLogo);
}
I know I'd selected the anwer by menuka devinda but looking at the comments below it I concurred and tried to come up with a better solution. I managed to come up with this and in my opinion it's a much more elegant solution:
input[type='radio'], label{
vertical-align: baseline;
padding: 10px;
margin: 10px;
}
Thanks to everyone who offered an answer, your answer didn't go unnoticed. If you still got any other ideas feel free to add your own answer to this question.
For me I solved it by changing passwords from Arabic letter to English letter, but first I went to the folder and deleted the generated key then it works.
You'd need to wrap the two headings in a div
tag, and have that div tag use a style that does clear: both
. e.g:
<div style="clear: both">
<h2 style="float: left">Heading 1</h2>
<h3 style="float: right">Heading 2</h3>
</div>
<hr />
Having the hr
after the div
tag will ensure that it is pushed beneath both headers.
Or something very similar to that. Hope this helps.
Consider you've created a procedure like below.
CREATE OR REPLACE PROCEDURE GET_FULL_NAME like
(
FIRST_NAME IN VARCHAR2,
LAST_NAME IN VARCHAR2,
FULL_NAME OUT VARCHAR2
) IS
BEGIN
FULL_NAME:= FIRST_NAME || ' ' || LAST_NAME;
END GET_FULL_NAME;
In Oracle SQL Developer, you can run this procedure in two ways.
1. Using SQL Worksheet
Create a SQL Worksheet and write PL/SQL anonymous block like this and hit f5
DECLARE
FULL_NAME Varchar2(50);
BEGIN
GET_FULL_NAME('Foo', 'Bar', FULL_NAME);
Dbms_Output.Put_Line('Full name is: ' || FULL_NAME);
END;
2. Using GUI Controls
Expand Procedures
Right click on the procudure you've created and Click Run
In the pop-up window, Fill the parameters and Click OK.
Cheers!
What about just using virtual desktops? You can spread your windows around among multiple workspaces. Something like Virtual Dimension should give you most of that functionality. I use virtual desktops all the time on Linux, and it's the next best thing to multiple monitors.
I have had this error for some time as well. It might be some kind of netbeans bug that has to do with netbeans connector. I can't find any mention of favicon.ico

mattgcon,
Should work, do you get more rows if you run the same SQL with the "NOT LIKE" line commented out? If not, check the data. I know you mentioned in your question, but check that the actual SQL statement is using that clause. The other answers with NULL are also a good idea.
This works for me in irb:
irb> (1..4).to_a
=> [1, 2, 3, 4]
I notice that:
irb> 1..4.to_a
(irb):1: warning: default `to_a' will be obsolete
ArgumentError: bad value for range
from (irb):1
So perhaps you are missing the parentheses?

Not really and I am talking about SQL Server. The temp table (with single #) exists and is visible within the scope it is created (scope-bound). Each time you call your stored procedure it creates a new scope and therefore that temp table exists only in that scope. I believe the temp tables are also visible to stored procedures and udfs that're called within that scope as well. If you however use double pound (##) then they become global within your session and therefore visible to other executing processes as part of the session that the temp table is created in and you will have to think if the possibility of temp table being accessed concurrently is desirable or not.
To set Maven Proxy :
Edit the proxies session in your ~/.m2/settings.xml file. If you cant find the file, create one.
<settings>

<protocol>http</protocol>
<host>your-proxy-host</host>
<port>your-proxy-port</port>

If you want to put something back into that div
, the innerHTML
is probably better.
My example:
<ul><div id="result"></div></ul>
<script>
function displayHTML(result){
var movieLink = document.createElement("li");
var t = document.createTextNode(result.Title);
movieLink.appendChild(t);
outputDiv.appendChild(movieLink);
}
</script>
If I use the .firstChild
or .lastChild
method the displayHTML()
function doesnt work afterwards, but no problem with the .innerHTML
method.

Towards the second half of Create REST API using ASP.NET MVC that speaks both JSON and plain XML, to quote:
Now we need to accept JSON and XML payload, delivered via HTTP POST. Sometimes your client might want to upload a collection of objects in one shot for batch processing. So, they can upload objects using either JSON or XML format. There's no native support in ASP.NET MVC to automatically parse posted JSON or XML and automatically map to Action parameters. So, I wrote a filter that does it."
He then implements an action filter that maps the JSON to C# objects with code shown.
Raugaral's answer but with -p functionality. Ugly, but it works:
function mkdirp(dir) {
let dirs = dir.split(/\\/).filter(asdf => !asdf.match(/^\s*$/))
let fullpath = ''
// Production directory will begin \\, test is on my local drive.
if (dirs[0].match(/C:/i)) {
fullpath = dirs[0] + '\\'
}
else {
fullpath = '\\\\' + dirs[0] + '\\'
}
// Start from root directory + 1, build out one level at a time.
dirs.slice(1).map(asdf => {
fullpath += asdf + '\\'
if (!fs.existsSync(fullpath)) {
fs.mkdirSync(fullpath)
}
})
}//mkdirp
Given the Django use case, there are two answers to this. Here is its django.utils.html.escape
function, for reference:
def escape(html):
"""Returns the given HTML with ampersands, quotes and carets encoded."""
return mark_safe(force_unicode(html).replace('&', '&').replace('<', '&l
t;').replace('>', '>').replace('"', '"').replace("'", '''))
To reverse this, the Cheetah function described in Jake's answer should work, but is missing the single-quote. This version includes an updated tuple, with the order of replacement reversed to avoid symmetric problems:
def html_decode(s):
"""
Returns the ASCII decoded version of the given HTML string. This does
NOT remove normal HTML tags like <p>.
"""
htmlCodes = (
("'", '''),
('"', '"'),
('>', '>'),
('<', '<'),
('&', '&')
)
for code in htmlCodes:
s = s.replace(code[1], code[0])
return s
unescaped = html_decode(my_string)
This, however, is not a general solution; it is only appropriate for strings encoded with django.utils.html.escape
. More generally, it is a good idea to stick with the standard library:
# Python 2.x:
import HTMLParser
html_parser = HTMLParser.HTMLParser()
unescaped = html_parser.unescape(my_string)
# Python 3.x:
import html.parser
html_parser = html.parser.HTMLParser()
unescaped = html_parser.unescape(my_string)
# >= Python 3.5:
from html import unescape
unescaped = unescape(my_string)
As a suggestion: it may make more sense to store the HTML unescaped in your database. It'd be worth looking into getting unescaped results back from BeautifulSoup if possible, and avoiding this process altogether.
With Django, escaping only occurs during template rendering; so to prevent escaping you just tell the templating engine not to escape your string. To do that, use one of these options in your template:
{{ context_var|safe }}
{% autoescape off %}
{{ context_var }}
{% endautoescape %}
Some other alternatives for copying ArrayList as a Deep Copy
Alernative 1 - Use of external package commons-lang3, method SerializationUtils.clone():
SerializationUtils.clone()
Let's say we have a class dog where the fields of the class are mutable and at least one field is an object of type String and mutable - not a primitive data type (otherwise shallow copy would be enough).
Example of shallow copy:
List<Dog> dogs = getDogs(); // We assume it returns a list of Dogs
List<Dog> clonedDogs = new ArrayList<>(dogs);
Now back to deep copy of dogs.
The Dog class does only have mutable fields.
Dog class:
public class Dog implements Serializable {
private String name;
private int age;
public Dog() {
// Class with only mutable fields!
this.name = "NO_NAME";
this.age = -1;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "Dog{" +
"name='" + name + '\'' +
", age=" + age +
'}';
}
}
Note that the class Dog implements Serializable! This makes it possible to utilize method "SerializationUtils.clone(dog)"
Read the comments in the main method to understand the outcome. It shows that we have successfully made a deep copy of ArrayList(). See below "SerializationUtils.clone(dog)" in context:
public static void main(String[] args) {
Dog dog1 = new Dog();
dog1.setName("Buddy");
dog1.setAge(1);
Dog dog2 = new Dog();
dog2.setName("Milo");
dog2.setAge(2);
List<Dog> dogs = new ArrayList<>(Arrays.asList(dog1,dog2));
// Output: 'List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]'
System.out.println("List dogs: " + dogs);
// Let's clone and make a deep copy of the dogs' ArrayList with external package commons-lang3:
List<Dog> clonedDogs = dogs.stream().map(dog -> SerializationUtils.clone(dog)).collect(Collectors.toList());
// Output: 'Now list dogs are deep copied into list clonedDogs.'
System.out.println("Now list dogs are deep copied into list clonedDogs.");
// A change on dog1 or dog2 can not impact a deep copy.
// Let's make a change on dog1 and dog2, and test this
// statement.
dog1.setName("Bella");
dog1.setAge(3);
dog2.setName("Molly");
dog2.setAge(4);
// The change is made on list dogs!
// Output: 'List dogs after change: [Dog{name='Bella', age=3}, Dog{name='Molly', age=4}]'
System.out.println("List dogs after change: " + dogs);
// There is no impact on list clonedDogs's inner objects after the deep copy.
// The deep copy of list clonedDogs was successful!
// If clonedDogs would be a shallow copy we would see the change on the field
// "private String name", the change made in list dogs, when setting the names
// Bella and Molly.
// Output clonedDogs:
// 'After change in list dogs, no impact/change in list clonedDogs:\n'
// '[Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]\n'
System.out.println("After change in list dogs, no impact/change in list clonedDogs: \n" + clonedDogs);
}
Output:
List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]
Now list dogs are deep copied into list clonedDogs.
List dogs after change: [Dog{name='Bella', age=3}, Dog{name='Molly', age=4}]
After change in list dogs, no impact/change in list clonedDogs:
[Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]
Comment: Since there is no impact/change on list clonedDogs after changing list dogs, then deep copy of ArrayList is successful!
Alernative 2 - Use of no external packages:
A new method "clone()" is introduced in the Dog class and "implements Serializable" is removed compare to alternative 1.
clone()
Dog class:
public class Dog {
private String name;
private int age;
public Dog() {
// Class with only mutable fields!
this.name = "NO_NAME";
this.age = -1;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
/**
* Returns a deep copy of the Dog
* @return new instance of {@link Dog}
*/
public Dog clone() {
Dog newDog = new Dog();
newDog.setName(this.name);
newDog.setAge(this.age);
return newDog;
}
@Override
public String toString() {
return "Dog{" +
"name='" + name + '\'' +
", age=" + age +
'}';
}
}
Read the comments in the main method below to understand the outcome. It shows that we have successfully made a deep copy of ArrayList(). See below "clone()" method in context:
public static void main(String[] args) {
Dog dog1 = new Dog();
dog1.setName("Buddy");

List<Dog> dogs = new ArrayList<>(Arrays.asList(dog1,dog2));
// Output: 'List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]'
System.out.println("List dogs: " + dogs);
// Let's clone and make a deep copy of the dogs' ArrayList:
List<Dog> clonedDogs = dogs.stream().map(dog -> dog.clone()).collect(Collectors.toList());
// Output: 'Now list dogs are deep copied into list clonedDogs.'
System.out.println("Now list dogs are deep copied into list clonedDogs.");
// A change on dog1 or dog2 can not impact a deep copy.
// Let's make a change on dog1 and dog2, and test this

// '[Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]\n'
System.out.println("After change in list dogs, no impact/change in list clonedDogs: \n" + clonedDogs);
}
Output:
List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]
Now list dogs are deep copied into list clonedDogs.
List dogs after change: [Dog{name='Bella', age=3}, Dog{name='Molly', age=4}]
After change in list dogs, no impact/change in list clonedDogs:
[Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]
Comment: Since there is no impact/change on list clonedDogs after changing list dogs, then deep copy of ArrayList is successful!
Note1: Alternative 1 is much slower than Alternative 2, but easier to mainatain since you do not need to upadate any methods like clone().
Note2: For alternative 1 the following maven dependency was used for method "SerializationUtils.clone()":

You could create a view with your criteria and then export the view?
First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:
global $db;
And I guess, when you wrote:
if($result->num_rows){
return (mysqli_result($query, 0) == 1) ? true : false;
what you really wanted was:
if ($result->num_rows==1) { return true; } else { return false; }
==
tests object references, .equals()
tests the string values.
Sometimes it looks as if ==
compares values, because Java does some behind-the-scenes stuff to make sure identical in-line strings are actually the same object.
For example:
String fooString1 = new String("foo");
String fooString2 = new String("foo");
// Evaluates to false
fooString1 == fooString2;
// Evaluates to true
fooString1.equals(fooString2);
// Evaluates to true, because Java uses the same object
"bar" == "bar";
But beware of nulls!
==
handles null
strings fine, but calling .equals()
from a null string will cause an exception:
String nullString1 = null;
String nullString2 = null;
// Evaluates to true
System.out.print(nullString1 == nullString2);
// Throws a NullPointerException
System.out.print(nullString1.equals(nullString2));
So if you know that fooString1
may be null, tell the reader that by writing
System.out.print(fooString1 != null && fooString1.equals("bar"));
The following are shorter, but it’s less obvious that it checks for null:
System.out.print("bar".equals(fooString1)); // "bar" is never null
System.out.print(Objects.equals(fooString1, "bar")); // Java 7 required

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html
That will get you up and running in about 10 minutes.
There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229
Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.
Basically you need apache / php running.

This may seem slightly off topic but this was the post I came across when wondering what happens when you read a column as a dateTime in c#. The post reflects the information I would have liked to be able to find about this mechanism. If you worry about utc and timezones then read on
I did a little more research as I'm always very wary of DateTime as a class because of its automatic assumptions about what timezone you are using and because it is way too easy to confuse local times and utc times.
What I'm trying to avoid here is DateTime going 'oh look the computer I'm being run on is in timezone x, therefore this time must also be in timezone x, when I get asked for my values I'll reply as if I'm in that timezone'
I was trying to read a datetime2
column.
The date time you will get back from sql server will end up being of Kind.Unspecified
this seems to mean it gets treated like UTC, which is what I wanted.
When reading a date
column you also have to read it as a DateTime
even though it has no time and is even more prone to screwing up by timezones (as it is on midnight).
I'd certainly consider this to be safer way of reading the DateTime as I suspect it can probably be modified by either settings in sql server or static settings in your c#:
var time = reader.GetDateTime(1);
var utcTime = new DateTime(time.Ticks, DateTimeKind.Utc);
From there you can get the components (Day, Month, Year) etc and format how you like.
If what you have is actually a date + a time then Utc might not be what you want there - since you are mucking around on the client you may need to convert it to a local time first (depending on what the meaning of the time is). However that opens up a whole can of worms.. If you need to do that I'd recommend using a library like noda time. There is TimeZoneInfo
in the standard library but after briefly investigating it, it doesn't seem to have a proper set of timezones. You can see the list provided by TimeZoneInfo
by using the method TimeZoneInfo.GetSystemTimeZones();
I also discovered sql server management studio doesn't convert times to local time before displaying them. Which is a relief!
You should've kept that DOM ready function
$(function() {
$("#projectKey").change(function() {
alert( $('option:selected', this).text() );
});
});
The document isn't ready if you added the javascript before the elements in the DOM, you have to either use a DOM ready function or add the javascript after the elements, the usual place is right before the </body>
tag
For a data.table, assigning the column to NULL removes it:
DT[,c("col1", "col1", "col2", "col2")] <- NULL
^
|---- Notice the extra comma if DT is a data.table
... which is the equivalent of:
DT$col1 <- NULL
DT$col2 <- NULL
DT$col3 <- NULL
DT$col4 <- NULL
The equivalent for a data.frame is:
DF[c("col1", "col1", "col2", "col2")] <- NULL
^
|---- Notice the missing comma if DF is a data.frame
Q. Why is there a comma in the version for data.table, and no comma in the version for data.frame?
A. As data.frames are stored as a list of columns, you can skip the comma. You could also add it in, however then you will need to assign them to a list of NULL
s, DF[, c("col1", "col2", "col3")] <- list(NULL)
.
Or download composer.phar from site: "https://getcomposer.org/download/" (manual download), and use command:

MSBuild in an independent build tool that is frequently bundled with other tools. It may have been installed on your computer with .NET (older versions), Visual Studio (newer versions), or even Team Foundation Build.
MSBuild needs configuration files, compilers, etc (a ToolSet) that matches the version of Visual Studio or TFS that will use it, as well as the version of .NET against which source code will be compiled.
Depending on how MSBuild was installed, the configuration files may be in one or more of these paths.
As described in other answers, a registry item and/or environmental variable point must to the ToolSet path.
Occasionally, an operation like installing a tool will leave the registry and/or environmental variable set incorrectly. The other answers are all variations on fixing them.
The only thing I have to add is the environmental variable didn't work for me when I left off the trailing \
Before compiling make sure that "rules.mk" file is included properly in Makefile or include it explicitly by:

Problem: errno 150 on table X when trying to do Forward Engineering on a DB diagram, 20 out of 21 succeeded, 1 failed. If FKs on table X were deleted, the error moved to a different table that wasn't failing before.
Changed all tables engine to myISAM and it worked just fine.
I had this problem too.
SVN doesn't do any line ending conversion, so files are committed with CRLF line endings intact. If you then use git-svn to put the project into git then the CRLF endings persist across into the git repository, which is not the state git expects to find itself in - the default being to only have unix/linux (LF) line endings checked in.
When you then check out the files on windows, the autocrlf conversion leaves the files intact (as they already have the correct endings for the current platform), however the process that decides whether there is a difference with the checked in files performs the reverse conversion before comparing, resulting in comparing what it thinks is an LF in the checked out file with an unexpected CRLF in the repository.
As far as I can see your choices are:
Footnote: if you choose option #2 then my experience is that some of the ancillary tools (rebase, patch etc) do not cope with CRLF files and you will end up sooner or later with files with a mix of CRLF and LF (inconsistent line endings). I know of no way of getting the best of both.
If you only want to animate the height of a view (from say 0 to a certain number) you could implement your own animation:
final View v = getTheViewToAnimateHere();
Animation anim=new Animation(){
protected void applyTransformation(float interpolatedTime, Transformation t) {
super.applyTransformation(interpolatedTime, t);
// Do relevant calculations here using the interpolatedTime that runs from 0 to 1
v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, (int)(30*interpolatedTime)));
}};
anim.setDuration(500);
v.startAnimation(anim);
Try using the SQL_NO_CACHE (MySQL 5.7) option in your query. (MySQL 5.6 users click HERE )
eg.
SELECT SQL_NO_CACHE * FROM TABLE
This will stop MySQL caching the results, however be aware that other OS and disk caches may also impact performance. These are harder to get around.
You can use jquery animate function for that.
$({ countNum: $('.code').html() }).animate({ countNum: 4000 }, {
duration: 8000,
easing: 'linear',
step: function () {
$('.code').html(Math.floor(this.countNum) );
},
complete: function () {
$('.code').html(this.countNum);
//alert('finished');
}
});

{
field1 = y.field1,
active = x.active
}).Take(10).ToList();

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).
The only difference would be if you try to reassign it before the end of this very file.
It's also useful to note that you can run the underlying MapReduce jobs with either the source or target cluster like so:
hadoop --config /path/to/hadoop/config distcp <src> <dst>
You can pass this
to each block. See here: http://jsfiddle.net/yR7TZ/1/
{{#each this}}
<div class="row"></div>
{{/each}}
Got this problem to, and finaly, I build myself a short solution. You just have to ellipsize manually the line you want, your maxLine attribute will cut your text.
This example cut your text for 3 lines max
final TextView title = (TextView)findViewById(R.id.text);
title.setText("A really long text");
ViewTreeObserver vto = title.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
ViewTreeObserver obs = title.getViewTreeObserver();
obs.removeGlobalOnLayoutListener(this);
if(title.getLineCount() > 3){
Log.d("","Line["+title.getLineCount()+"]"+title.getText());
int lineEndIndex = title.getLayout().getLineEnd(2);
String text = title.getText().subSequence(0, lineEndIndex-3)+"...";
title.setText(text);
Log.d("","NewText:"+text);
}
}
});
You can use set_xticklabels()
ax.set_xticklabels(df['Names'], rotation=90, ha='right')

Try below Query, was working for me to find Nth highest number salary. Just replace your number with nth_No

$(document)[0].styleSheets[styleSheetIndex].insertRule(rule, lineIndex);
styleSheetIndex
is the index value that corresponds to which order you loaded the file in the <head>
(e.g. 0 is the first file, 1 is the next, etc. if there is only one CSS file, use 0).
rule
is a text string CSS rule. Like this: "body { display:none; }"
.
lineIndex
is the line number in that file. To get the last line number, use $(document)[0].styleSheets[styleSheetIndex].cssRules.length
. Just console.log
that styleSheet object, it's got some interesting properties/methods.
Because CSS is a "cascade", whatever rule you're trying to insert for that selector you can just append to the bottom of the CSS file and it will overwrite anything that was styled at page load.
In some browsers, after manipulating the CSS file, you have to force CSS to "redraw" by calling some pointless method in DOM JS like document.offsetHeight
(it's abstracted up as a DOM property, not method, so don't use "()") -- simply adding that after your CSSOM manipulation forces the page to redraw in older browsers.
So here's an example:
var stylesheet = $(document)[0].styleSheets[0];
stylesheet.insertRule('body { display:none; }', stylesheet.cssRules.length);
From the proverbial horse's mouth...
When developing your app, you may find it necessary to share data, context or services globally across your app. For example, if your app has session data, such as the currently logged-in user, you will likely want to expose this information. In Android, the pattern for solving this problem is to have your android.app.Application instance own all global data, and then treat your Application instance as a singleton with static accessors to the various data and services.
When writing an Android app, you're guaranteed to only have one instance of the android.app.Application class, and so it's safe (and recommended by Google Android team) to treat it as a singleton. That is, you can safely add a static getInstance() method to your Application implementation. Like so:
public class AndroidApplication extends Application {
private static AndroidApplication sInstance;
public static AndroidApplication getInstance(){
return sInstance;
}
@Override
public void onCreate() {
super.onCreate();
sInstance = this;
}
}
My solution to not having sessionStorage transferable over tabs was to create a localProfile and bang off this variable. If this variable is set but my sessionStorage variables arent go ahead and reinitialize them. When user logs out window closes destroy this localStorage variable
This should work:
find DIR_NAME -type f | wc -l
Explanation:
-type f
to include only files.|
(and not ¦
) redirects find
command's standard output to wc
command's standard input.wc
(short for word count) counts newlines, words and bytes on its input (docs).-l
to count just newlines.Notes:
DIR_NAME
with .
to execute the command in the current folder.-type f
to include directories (and symlinks) in the count.Explanation of why your example does not work:
In the command you showed, you do not use the "Pipe" (|
) to kind-of connect two commands, but the broken bar (¦
) which the shell does not recognize as a command or something similar. That's why you get that error message.
If you load you table file with dtype=str
or convert column type to string df['a'] = df['a'].astype(str)
then you can use such approach:
df['a']= 'col' + df['a'].str[:]
This approach allows prepend, append, and subset string of df
.

You can actually use a facility built in to the Java runtime to do this. The SunJCE in Java 6 supports PBKDF2, which is a good algorithm to use for password hashing.
byte[] salt = new byte[16];
random.nextBytes(salt);
KeySpec spec = new PBEKeySpec("password".toCharArray(), salt, 65536, 128);
SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] hash = f.generateSecret(spec).getEncoded();
Base64.Encoder enc = Base64.getEncoder();
System.out.printf("salt: %s%n", enc.encodeToString(salt));
System.out.printf("hash: %s%n", enc.encodeToString(hash));
Here's a utility class that you can use for PBKDF2 password authentication:
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.spec.InvalidKeySpecException;

For your example, Dirk's answer is perfect. If you instead had a data frame and wanted to add that sort of sequence as a column, you could also use group
from groupdata2 (disclaimer: my package) to greedily divide the datapoints into groups.
# Attach groupdata2
library(groupdata2)
# Create a random data frame
df <- data.frame("x" = rnorm(27))
# Create groups with 5 members each (except last group)
group(df, n = 5, method = "greedy")
x .groups
<dbl> <fct>
1 0.891 1
2 -1.13 1
3 -0.500 1
4 -1.12 1
5 -0.0187 1
6 0.420 2
7 -0.449 2
8 0.365 2
9 0.526 2
10 0.466 2
# … with 17 more rows
There's a whole range of methods for creating this kind of grouping factor. E.g. by number of groups, a list of group sizes, or by having groups start when the value in some column differs from the value in the previous row (e.g. if a column is c("x","x","y","z","z")
the grouping factor would be c(1,1,2,3,3)

In Ruby, the Hash#select is a right option. If you work with Rails, you can use Hash#slice and Hash#slice!. e.g. (rails 3.2.13)
h1 = {:a => 1, :b => 2, :c => 3, :d => 4}
h1.slice(:a, :b) # return {:a=>1, :b=>2}, but h1 is not changed
h2 = h1.slice!(:a, :b) # h1 = {:a=>1, :b=>2}, h2 = {:c => 3, :d => 4}
"Using the dollar sign is not very common in JavaScript, but professional programmers often use it as an alias for the main function in a JavaScript library.

I go against convention here. I don't like typedef's to base types. I think it's a useless indirection that removes value.
You can use the DateTime.Add() method to add the time to the date.
DateTime date = DateTime.Now;
TimeSpan time = new TimeSpan(36, 0, 0, 0);
DateTime combined = date.Add(time);
Console.WriteLine("{0:dddd}", combined);
You can also create your timespan by parsing a String, if that is what you need to do.
Alternatively, you could look at using other controls. You didn't mention if you are using winforms, wpf or asp.net, but there are various date and time picker controls that support selection of both date and time.
Use:
git reset HEAD^
That does a "mixed" reset by default, which will do what you asked; put foo.java in unstaged, removing the most recent commit.
It's Python; anything goes. Consider how to publish your documentation. Docstrings are invisible except to readers of your source code.
People really like to browse and search documentation on the web. To achieve that, use the documentation tool Sphinx. It's the de-facto standard for documenting Python projects. The product is beautiful - take a look at https://python-guide.readthedocs.org/en/latest/ . The website Read the Docs will host your docs for free.
As said by Sparky in comments on many answers to this question, there is NOT any textarea
value for the type
attribute of the input
tag.
On other terms, the following markup is not valid :
<input type="textarea" />
And the browser replaces it by the default :
<input type="text" />
To define a multi-lines text input, use :
<textarea></textarea>
See the textarea element documentation for more details.
In angularjs this should works:

Once you have selected an element you can call click()
document.getElementById('link').click();

Yes, they're in the same "local scope", and actually code like this is common in Python:
if condition:
x = 'something'
else:
x = 'something else'
use(x)
Note that x
isn't declared or initialized before the condition, like it would be in C or Java, for example.
In other words, Python does not have block-level scopes. Be careful, though, with examples such as
if False:
x = 3
print(x)
which would clearly raise a NameError
exception.
If you can count on having a period of time where the table is in a stable state with no new inserts going on, this should do it (untested):
DECLARE
last_used NUMBER;
curr_seq NUMBER;
BEGIN
SELECT MAX(pk_val) INTO last_used FROM your_table;
LOOP
SELECT your_seq.NEXTVAL INTO curr_seq FROM dual;
IF curr_seq >= last_used THEN EXIT;
END IF;
END LOOP;
END;
This enables you to get the sequence back in sync with the table, without dropping/recreating/re-granting the sequence. It also uses no DDL, so no implicit commits are performed. Of course, you're going to have to hunt down and slap the folks who insist on not using the sequence to populate the column...
I have a blog post on how to increase the file size for asp upload control.
From the post:
By default, the FileUpload control allows a maximum of 4MB file to be uploaded and the execution timeout is 110 seconds. These properties can be changed from within the web.config file’s httpRuntime section. The maxRequestLength property determines the maximum file size that can be uploaded. The executionTimeout property determines the maximum time for execution.

You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
What you want is an implementation of the observer pattern. You can do it yourself completely, or use java classes like java.util.Observer

One other difference lies in the performance.
As the DLL is loaded at runtime by the .exe(s), the .exe(s) and the DLL work with shared memory concept and hence the performance is low relatively to static linking.
On the other hand, a .lib is code that is linked statically at compile time into every process that requests. Hence the .exe(s) will have single memory, thus increasing the performance of the process.
ord()
will not work because your end string is two characters long.
Returns the ASCII value of the first character of string.
From my testing, you need to check that the end
string doesn't get "stepped over". The perl-style character incrementation is a cool method, but it is a single-stepping method. For this reason, an inner loop helps it along when necessary. This is actually not a bother, in fact, it is useful because we need to check if the loop(s) should be broken on each single step.

function excelCols($letter,$end,$step=1){ // function doesn't check that $end is "later" than $letter
if($step==0)return []; // prevent infinite loop
do{
$letters[]=$letter; // store letter
for($x=0; $x<$step; ++$x){ // increment in accordance with $step declaration
if($letter===$end)break(2); // break if end is "stepped on"
++$letter;
}
}while(true);
return $letters;
}
echo implode(' ',excelCols('A','JJ',4));
echo "\n --- \n";
echo implode(' ',excelCols('A','BB',3));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',1));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',3));

$step=4;
// generate and store more than we need (this is an obvious method disadvantage)
$result=$array=range('A','Z',1); // store A - Z as $array and $result
foreach($array as $a){
foreach($array as $b){
$result[]="$a$b"; // store double letter combinations

//echo implode(' ',$result),"\n\n";
// slice away from the front of the array
$result=array_slice($result,array_search($start,$result)); // reindex keys
//echo implode(' ',$result),"\n\n";
// punch out elements that are not "stepped on"
$result=array_filter($result,function($k)use($step){return $k%$step==0;},ARRAY_FILTER_USE_KEY); // use modulo

EDIT: The "trick" used here involves:
Constructing a string that represents a currently evaluated command-line argument variable (i.e. "%1", "%2" etc.) using a string that contains a percent character (%%
) and a counter variable arg_idx
on each loop iteration.
Storing that string into a variable curr_arg_label
.
Passing both that string (!curr_arg_label!
) and a return variable's name (curr_arg_value
) to a primitive subprogram get_value
.
In the subprogram its first argument's (%1
) value is used on the left side of assignment (set
) and its second argument's (%2
) value on the right. However, when the second subprogram's argument is passed it is resolved into value of the main program's command-line argument by the command interpreter. That is, what is passed is not, for example, "%4" but whatever value the fourth command-line argument variable holds ("another_arg" in the sample usage).
Then the variable given to the subprogram as return variable (curr_arg_value
) is tested for being undefined, which would happen if currently evaluated command-line argument is absent. Initially this was a comparison of the return variable's value wrapped in square brackets to empty square brackets (which is the only way I know of testing program or subprogram arguments which may contain quotes and was an overlooked leftover from trial-and-error phase) but was since fixed to how it is now.

However it is advisable that you install your jar in the repository, and not commit it to the SCM - after all that's what maven tries to eliminate.
Looks like the answer is that, as of now, you can't.
http://exploringjs.com/es6/ch_modules.html#sec_module-loader-api
I think the intent is to enable static analysis as much as possible, and conditionally imported modules break that. Also worth mentioning -- I'm using Babel, and I'm guessing that System
is not supported by Babel because the module loader API didn't become an ES6 standard.

If you don't mind destroying the array (or a temp copy of it) you can do:
$stack = array("orange", "banana", "apple", "raspberry");
while ($fruit = array_pop($stack)){
echo $fruit . "\n<br>";
}
produces:
raspberry
apple
banana
orange
I think this solution reads cleaner than fiddling with an index and you are less likely to introduce index handling mistakes, but the problem with it is that your code will likely take slightly longer to run if you have to create a temporary copy of the array first. Fiddling with an index is likely to run faster, and it may also come in handy if you actually need to reference the index, as in:
$stack = array("orange", "banana", "apple", "raspberry");
$index = count($stack) - 1;
while($index > -1){
echo $stack[$index] ." is in position ". $index . "\n<br>";
$index--;
}
But as you can see, you have to be very careful with the index...
To configure Docker to work with a proxy you need to add the HTTPS_PROXY / HTTP_PROXY environment variable to the Docker sysconfig file (/etc/sysconfig/docker
).
Depending on if you use init.d
or the services tool you need to add the "export" statement (due to Debian Bug report logs - #767441. Examples in /etc/default/docker are misleading regarding the supported syntax):
HTTPS_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
HTTP_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
export HTTP_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
export HTTPS_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
The Docker repository (Docker Hub) only supports HTTPS. To get Docker working with SSL intercepting proxies you have to add the proxy root certificate to the systems trust store.
For CentOS, copy the file to /etc/pki/ca-trust/source/anchors/
and update the CA trust store and restart the Docker service.
If your proxy uses NTLMv2 authentication - you need to use intermediate proxies like Cntlm to bridge the authentication. This blog post explains it in detail.
i suggest using phpmyadmin
it’s definitely the best free tool out there and it works on every system with php+mysql
Currently, MySQL doesn't allow to set multiple values in one method call. So you have to have it under your own control. I usually create one prepared statement for predefined number of parameters, then I add as many batches as I need.
int paramSizeInClause = 10; // required to be greater than 0!
String color = "FF0000"; // red
String name = "Nathan";
Date now = new Date();
String[] ids = "15,21,45,48,77,145,158,321,325,326,327,328,329,330,331,332,333,334,335,336,337,338,339,340,341,342,343,344,345,346,347,348,349,350,351,358,1284,1587".split(",");
// Build sql query
StringBuilder sql = new StringBuilder();
sql.append("UPDATE book SET color=? update_by=?, update_date=? WHERE book_id in (");
// number of max params in IN clause can be modified
// to get most efficient combination of number of batches
// and number of parameters in each batch
for (int n = 0; n < paramSizeInClause; n++) {
sql.append("?,");
}
if (sql.length() > 0) {
sql.deleteCharAt(sql.lastIndexOf(","));
}
sql.append(")");
PreparedStatement pstm = null;
try {
pstm = connection.prepareStatement(sql.toString());
int totalIdsToProcess = ids.length;
int batchLoops = totalIdsToProcess / paramSizeInClause + (totalIdsToProcess % paramSizeInClause > 0 ? 1 : 0);
for (int l = 0; l < batchLoops; l++) {
int i = 1;
pstm.setString(i++, color);
pstm.setString(i++, name);
pstm.setTimestamp(i++, new Timestamp(now.getTime()));
for (int count = 0; count < paramSizeInClause; count++) {
int param = (l * paramSizeInClause + count);
if (param < totalIdsToProcess) {
pstm.setString(i++, ids[param]);
} else {
pstm.setNull(i++, Types.VARCHAR);
}
}
pstm.addBatch();
}
} catch (SQLException e) {
} finally {
//close statement(s)
}
If you don't like to set NULL when no more parameters left, you can modify code to build two queries and two prepared statements. First one is the same, but second statement for the remainder (modulus). In this particular example that would be one query for 10 params and one for 8 params. You will have to add 3 batches for the first query (first 30 params) then one batch for the second query (8 params).
To the latest setup and information if you have installed the Android Studio (i.e. 1.5) and trying to target SDK 4.0 then you may not be able to locate and setup the and AVD Emulator with SDK-vX.XX (with Google API's).
See following steps in order to download the required library and start with that. AVD Emulator setup -setting up Emulator for SDK4.0 with GoogleAPI so Map application can work- In Android Studio
But unfortunately above method did not work well on my side. And was not able to created Emulator with API Level 17 (SDK 4.2). So I followed this post that worked on my side well. The reason seems that the Android Studio Emulator creation window has limited options/features.

update VersionedFields
set Value = replace(replace(value,'<iframe','<a>iframe'), '> </iframe>','</a>')
and you do it in a single pass.
Try operator instanceof
.
try using
View view_instance = (View)findViewById(R.id.nutrition_bar_filled);
view_instance.setWidth(10);
use Layoutparams to do so where you can set width and height like below.
LayoutParams lp = new LayoutParams(10,LayoutParams.wrap_content);
View_instance.setLayoutParams(lp);
pip3 install BeautifulSoup4
Try this. It works for me. The reason is well explained here..
Although, this may not be advisable.
If you want to get customer details, even when the user doesn’t create an account, but only makes an order, you could just query it, directly from the database.
Although, there may be performance issues, querying directly. But this surely works 100%.
You can search by post_id
and meta_keys
.
global $wpdb; // Get the global $wpdb
$order_id = {Your Order Id}
$table = $wpdb->prefix . 'postmeta';
$sql = 'SELECT * FROM `'. $table . '` WHERE post_id = '. $order_id;
$result = $wpdb->get_results($sql);
foreach($result as $res) {
if( $res->meta_key == 'billing_phone'){
$phone = $res->meta_value; // get billing phone
}
if( $res->meta_key == 'billing_first_name'){
$firstname = $res->meta_value; // get billing first name
}
// You can get other values
// billing_last_name
// billing_email
// billing_country
// billing_address_1
// billing_address_2
// billing_postcode
// billing_state
// customer_ip_address
// customer_user_agent
// order_currency
// order_key
// order_total
// order_shipping_tax
// order_tax
// payment_method_title
// payment_method
// shipping_first_name
// shipping_last_name
// shipping_postcode
// shipping_state
// shipping_city
// shipping_address_1
// shipping_address_2
// shipping_company

After trying literally every solution, I realised that the project I had been working on was previously using the latest Android Studio which was 3.2 at the time and the current pc I was using was running 2.2 after updating android studio this seemed to fix the issue completely for me.
Solution: Android Studio -> Check For Updates and then install latest build
Here's your answer:

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.
For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

Use constructor to convert it:
List<?> list = new ArrayList<?>(set);
Also, if your service is sending an object instead of an array add isArray:false to its declaration.
'query': {method: 'GET', isArray: false }
You simply have to use the filter
filter (see the documentation) :
<div id="totalPos">{{(tweets | filter:{polarity:'Positive'}).length}}</div>
<div id="totalNeut">{{(tweets | filter:{polarity:'Neutral'}).length}}</div>
<div id="totalNeg">{{(tweets | filter:{polarity:'Negative'}).length}}</div>
Use padding
on the cells and border-spacing
on the table. The former will give you cellpadding while the latter will give you cellspacing.
table { border-spacing: 5px; } /* cellspacing */
th, td { padding: 5px; } /* cellpadding */
It's not an answer, but...
To get datetime
components individually, better use datetime.timetuple:
time = datetime.now()
time.timetuple()
#-> time.struct_time(
# tm_year=2014, tm_mon=9, tm_mday=7,
# tm_hour=2, tm_min=38, tm_sec=5,
# tm_wday=6, tm_yday=250, tm_isdst=-1
#)
It's now easy to get the parts:
ts = time.timetuple()
ts.tm_year
ts.tm_mon
ts.tm_mday
ts.tm_hour
ts.tm_min
ts.tm_sec
First, using a page-file when you have 4 GB of RAM is useless. Windows can't access more than 4GB (actually, less because of memory holes) so the page file is not used.
Second, the address space is split in 2, half for kernel, half for user mode. If you need more RAM for your applications use the /3GB option in boot.ini (make sure java.exe is marked as "large address aware" (google for more info).
Third, I think you can't allocate the full 2 GB of address space because java wastes some memory internally (for threads, JIT compiler, VM initialization, etc). Use the /3GB switch for more.
You have got the PATH slightly wrong. You need the PATH to "the containing directory", not the actual executable itself.
Your PATH should be set like this:
export PATH=/Library/PostgreSQL/9.5/bin:$PATH
without the extra sql
part in it. Also, you must remove the spaces around the equals sign.
Keywords: Postgresql, PATH, macOS, OSX, psql
I had exactly same problem, my solution was to
scp -i /path/pem -r /path/file/ ec2-user@public aws dns name:
(leave it blank here)
once you done this part, get into ssh server and mv file to desired location
If your data field is already a DateTime datatype, you don't need to use [DataType(DataType.Date)]
for the annotation; just use:
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
on the jQuery, use datepicker for you calendar
$(document).ready(function () {
$('#StartDate').datepicker();
});
on your HTML, use EditorFor
helper:
@Html.EditorFor(model => model.StartDate)
If you want to code this yourself instead of using the built-in function hex()
, you can simply do the recursive call before you print the current digit:
def ChangeHex(n):
if (n < 0):
print(0)
elif (n<=1):
print n,
else:
ChangeHex( n / 16 )
x =(n%16)
if (x < 10):
print(x),
if (x == 10):
print("A"),
if (x == 11):
print("B"),
if (x == 12):
print("C"),
if (x == 13):
print("D"),
if (x == 14):
print("E"),
if (x == 15):
print ("F"),
You need to use the event.target
which is the element which originally triggered the event. The this
in your example code refers to document
.
In jQuery, that's...
$(document).click(function(event) {
var text = $(event.target).text();
});
Without jQuery...
document.addEventListener('click', function(e) {
e = e || window.event;
var target = e.target || e.srcElement,
text = target.textContent || target.innerText;
}, false);
Also, ensure if you need to support < IE9 that you use attachEvent()
instead of addEventListener()
.
You can have more than one statement when still return:
[]() -> your_type {return (
your_statement,
even_more_statement = just_add_comma,
return_value);}
If you're using MSTest, which originally didn't have an ExpectedException
attribute, you could do this:
try
{
SomeExceptionThrowingMethod()
Assert.Fail("no exception thrown");
}
catch (Exception ex)
{
Assert.IsTrue(ex is SpecificExceptionType);
}
i also have a solution with standard inputs and outputs
#include<stdio.h>
#include<malloc.h>
int main()
{
char *str,ch;
int size=10,len=0;
str=realloc(NULL,sizeof(char)*size);
if(!str)return str;
while(EOF!=scanf("%c",&ch) && ch!="\n")
{
str[len++]=ch;
if(len==size)
{
str = realloc(str,sizeof(char)*(size+=10));
if(!str)return str;
}
}
str[len++]='\0';
printf("%s\n",str);
free(str);
}
My PrintMax version for prevent bad line breaks on output:
CREATE PROCEDURE [dbo].[PrintMax](@iInput NVARCHAR(MAX))
AS
BEGIN
Declare @i int;
Declare @NEWLINE char(1) = CHAR(13) + CHAR(10);
While LEN(@iInput)>0 BEGIN
Set @i = CHARINDEX(@NEWLINE, @iInput)
if @i>8000 OR @i=0 Set @i=8000
Print SUBSTRING(@iInput, 0, @i)
Set @iInput = SUBSTRING(@iInput, @i+1, LEN(@iInput))
END

Using Angular?
This is a very important caveat to remember.
The base tag needs to not only be in the head but in the right location.
I had my base tag in the wrong place in the head, it should come before any tags with url requests. Basically placing it as the second tag underneath the title solved it for me.
<base href="/">
I wrote a little post on it here
If the accepted answer on this post doesn't work, give this a try:
I had EditorConfig for Visual Studio Code installed in my editor, and it kept overriding my user settings which were set to indent files using spaces. Every time I switched between editor tabs, my file would automatically get indented with tabs even if I had converted indentation to spaces!!!
Right after I uninstalled this extension, indentation no longer changes between switching editor tabs, and I can work more comfortably rather than having to manually convert tabs to spaces every time I switch files - that is painful.

According to oracle online documentation
ORA-12541: TNS:no listener
Cause: The connection request could not be completed because the listener is not running.
Action: Ensure that the supplied destination address matches one of the addresses used by
the listener - compare the TNSNAMES.ORA entry with the appropriate LISTENER.ORA file (or
TNSNAV.ORA if the connection is to go by way of an Interchange). Start the listener on
the remote machine.
you can use something like this:
$(this).addClass('someClass');
$(Selector).trigger('ClassChanged')
$(otherSelector).bind('ClassChanged', data, function(){//stuff });
but otherwise, no, there's no predefined function to fire an event when a class changes.

I see no proposal for 'switch'. Code example (run it):

You should know that destroy()
is correct method for removing an entity directly via object or model and delete()
can only be called in query builder.
In your case, You have not checked if record exists in database or not. Record can only be deleted if exists.
So, You can do it like follows.
$user = User::find($id);
if($user){
$destroy = User::destroy(2);
}
The value or $destroy
above will be 0 or 1 on fail or success respectively. So, you can alter the $data
array like:
if ($destroy){
$data=[
'status'=>'1',
'msg'=>'success'
];
}else{
$data=[
'status'=>'0',
'msg'=>'fail'
];
}
Hope, you understand.
That depends. Is it just a variable (in a method)? Or a class-member?
If it's just a variable you'll get an error that no value has been set when trying to read from it without first assinging it a value.
If it's a class-member it will be initialized to null by the VM.
You can get some inspiration by reading an entrypoint.sh
script written by the contributors from MySQL that checks whether the specified variables were set.
As the script shows, you can pipe them with -a
, e.g.:
if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then

The simple version is 0x is a prefix denoting a hexadecimal number, source.
So the value you're computing is after the prefix, in this case 10.
But that is not the number 10. The most significant bit 1
denotes the hex value while 0
denotes the units.
So the simple math you would do is
0x10
1 * 16 + 0 = 16
Note - you use 16 because hex is base 16.
Another example:
0xF7
15 * 16 + 7 = 247
You can get a list of values by searching for a hex table. For instance in this chart notice F corresponds with 15.
I created a possibly faster implementation by using 0-1 range for RGBS and V and 0-6 range for Hue (avoiding the division), and grouping the cases into two categories:
#include <math.h>
#include <float.h>
void fromRGBtoHSV(float rgb[], float hsv[])
{
// for(int i=0; i<3; ++i)
// rgb[i] = max(0.0f, min(1.0f, rgb[i]));
hsv[0] = 0.0f;
hsv[2] = max(rgb[0], max(rgb[1], rgb[2]));
const float delta = hsv[2] - min(rgb[0], min(rgb[1], rgb[2]));
if (delta < FLT_MIN)
hsv[1] = 0.0f;
else
{
hsv[1] = delta / hsv[2];
if (rgb[0] >= hsv[2])
{
hsv[0] = (rgb[1] - rgb[2]) / delta;
if (hsv[0] < 0.0f)
hsv[0] += 6.0f;
}
else if (rgb[1] >= hsv[2])
hsv[0] = 2.0f + (rgb[2] - rgb[0]) / delta;
else
hsv[0] = 4.0f + (rgb[0] - rgb[1]) / delta;
}
}
void fromHSVtoRGB(const float hsv[], float rgb[])
{
if(hsv[1] < FLT_MIN)
rgb[0] = rgb[1] = rgb[2] = hsv[2];
else
{
const float h = hsv[0];
const int i = (int)h;
const float f = h - i;
const float p = hsv[2] * (1.0f - hsv[1]);
if (i & 1) {
const float q = hsv[2] * (1.0f - (hsv[1] * f));
switch(i) {
case 1:
rgb[0] = q;
rgb[1] = hsv[2];
rgb[2] = p;
break;
case 3:
rgb[0] = p;
rgb[1] = q;
rgb[2] = hsv[2];
break;
default:
rgb[0] = hsv[2];
rgb[1] = p;
rgb[2] = q;
break;
}
}
else
{
const float t = hsv[2] * (1.0f - (hsv[1] * (1.0f - f)));
switch(i) {
case 0:
rgb[0] = hsv[2];
rgb[1] = t;
rgb[2] = p;
break;
case 2:
rgb[0] = p;
rgb[1] = hsv[2];
rgb[2] = t;
break;
default:
rgb[0] = t;
rgb[1] = p;
rgb[2] = hsv[2];
break;
}
}
}
}
For 0-255 range just * 255.0f + 0.5f and assign it to an unsigned char (or divide by 255.0 to get the opposite).
Tilde ~ matches minor version, if you have installed a package that has 1.4.2 and after your installation, versions 1.4.3 and 1.4.4 are also available if in your package.json it is used as ~1.4.2 then npm install in your project after upgrade will install 1.4.4 in your project. But there is 1.5.0 available for that package then it will not be installed by ~. It is called minor version.
Caret ^ matches major version, if 1.4.2 package is installed in your project and after your installation 1.5.0 is released then ^ will install major version. It will not allow to install 2.1.0 if you have ^1.4.2.
Fixed version if you don't want to change version of package on each installation then used fixed version with out any special character e.g "1.4.2"
Latest Version * If you want to install latest version then only use * in front of package name.

Official answer: http://blog.cocoapods.org/Master-Spec-Repo-Rate-Limiting-Post-Mortem/
As a result of this discussion https://github.com/CocoaPods/CocoaPods/issues/4989
Briefly: CocoaPods repository experiences a huge volume of fetches from GitHub and it was the problem. Changes have been available since version 1.0.0.beta.6.
Tips from this document:
If for whatever reason you cannot upgrade to version 1.0.0 just yet, you can perform the following steps to convert your clone of the Master spec-repo from a shallow to a full clone:
$ cd ~/.cocoapods/repos/master
$ git fetch --unshallow
My hack to first installation:
1. pod setup
2. Ctrl+C
After that I could find ~/.cocoapods/repos/ empty directory
3. Download https://github.com/CocoaPods/Specs/archive/master.zip
4. unpack it to ~/.cocoapods/repos/
5. Move to project folder
6. pod install --no-repo-update
Today it takes near 15 minutes
If your mock involves a network request, another alternative is to have a real test server to hit. You can use a service to generate a request and response for your testing.
Update: since the time I answered this there has been a lot of work on this look at Apache Arrow for a better read and write of parquet. Also: http://wesmckinney.com/blog/python-parquet-multithreading/
There is a python parquet reader that works relatively well: https://github.com/jcrobak/parquet-python
It will create python objects and then you will have to move them to a Pandas DataFrame so the process will be slower than pd.read_csv
for example.
A simple tkinter code for Python 3 for setting background image .
from tkinter import *
from tkinter import messagebox
top = Tk()
C = Canvas(top, bg="blue", height=250, width=300)
filename = PhotoImage(file = "C:\\Users\\location\\imageName.png")
background_label = Label(top, image=filename)
background_label.place(x=0, y=0, relwidth=1, relheight=1)
C.pack()
top.mainloop
Try this
select to_char(SYSDATE,'Month') from dual;
for full name and try this
select to_char(SYSDATE,'Mon') from dual;
for abbreviation
you can find more option here:
a simple way:
in view(pass the id value):
<td><?php echo anchor('textarea/delete_row?id='.$row->id, 'DELETE', 'id="$row->id"'); ?></td>
in controller(receive the id):
$id = $this->input->get('id');
$this->load->model('mod1');
$this->mod1->row_delete($id);
in model(get the passed args):
function row_delete($id){}
Actually, you should use the ajax to POST the id value to controller and delete the row, not the GET.
I used this extension method a lot in my project. Hope it will help one of you guys.
public static bool HasClass(this HtmlNode node, params string[] classValueArray)
{
var classValue = node.GetAttributeValue("class", "");
var classValues = classValue.Split(' ');
return classValueArray.All(c => classValues.Contains(c));
}
It might be a little late to the discussion but inevitably someone will stumble onto this post like I did. I found the answer I was looking for and thought I'd post my own take on it. The following JSfiddle includes how to layer .PNG's with transparency. Jerska's mention of the transparency attribute for the div's CSS was the solution: http://jsfiddle.net/jyef3fqr/
HTML:
<button id="toggle-box">toggle</button>
<div id="box" style="display:none;" ><img src="x"></div>
<button id="toggle-box2">toggle</button>
<div id="box2" style="display:none;"><img src="xx"></div>
<button id="toggle-box3">toggle</button>
<div id="box3" style="display:none;" ><img src="xxx"></div>
CSS:
#box {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:1;
}
#box2 {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:2;
background-color : transparent;
}
#box3 {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:2;
background-color : transparent;
}
body {background-color:#c0c0c0; }
JS:
$('#toggle-box').click().toggle(function() {
$('#box').animate({ width: 'show' });
}, function() {
$('#box').animate({ width: 'hide' });
});
$('#toggle-box2').click().toggle(function() {
$('#box2').animate({ width: 'show' });
}, function() {
$('#box2').animate({ width: 'hide' });
});
$('#toggle-box3').click().toggle(function() {
$('#box3').animate({ width: 'show' });
}, function() {
$('#box3').animate({ width: 'hide' });
});
And my original inspiration:http://jsfiddle.net/5g1zwLe3/ I also used paint.net for creating the transparent PNG's, or rather the PNG's with transparent BG's.
server.close() takes a while to close the connection, thus we should make this an asynchronous call as such:
await server.close();
IMPORTANT: when using await, we must use the async keyword in our encapsulating function as such:
async () => {
await server.close();
}
You can also do this:
<ul id="example">
<li>First</li>
<li>Second</li>
<li>Third</li>
<li>Fourth</li>
</ul>
// possibility 1
$('#example li:last').val();
// possibility 2
$('#example').children().last()
// possibility 3
$('#example li:last-child').val();
rm -rf some_dir
-r "recursive" -f "force" (suppress confirmation messages)

You have to insert the elements using the insert method present in vectors STL, check the below program to add the elements to it, and you can use in the same way in your program.
#include <iostream>
#include <vector>
#include <string.h>
int main ()
{
std::vector<std::string> myvector ;
std::vector<std::string>::iterator it;
it = myvector.begin();
std::string myarray [] = { "Hi","hello","wassup" };
myvector.insert (myvector.begin(), myarray, myarray+3);
std::cout << "myvector contains:";
for (it=myvector.begin(); it<myvector.end(); it++)
std::cout << ' ' << *it;
std::cout << '\n';
return 0;
}
This regex selects all spaces, you can use this and replace it with a single space
\s+
example in python
result = re.sub('\s+',' ', data))
Your JAXB is looking at both the getTimeSeries()
method and the member timeSeries
. You don't say which JAXB implementation you're using, or its configuration, but the exception is fairly clear.
at public java.util.List testjaxp.ModeleREP.getTimeSeries()
and
at protected java.util.List testjaxp.ModeleREP.timeSeries
You need to configure you JAXB stuff to use annotations (as per your @XmlElement(name="TimeSeries")
) and ignore public methods.
Arrays are default passed by pointers. You can try modifying an array inside a function call for better understanding.
One of the reason may be improper date/time of your PC.
In Ubuntu PC to check the date and time using:
date
Example, One of the ways to update date and time is:
date -s "23 MAR 2017 17:06:00"
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
formatter.setLenient(false);
try {
Date date= formatter.parse("02/03/2010");
} catch (ParseException e) {
//If input date is in different format or invalid.
}
formatter.setLenient(false) will enforce strict matching.
If you are using Joda-Time -
private boolean isValidDate(String dateOfBirth) {
boolean valid = true;
try {
DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
DateTime dob = formatter.parseDateTime(dateOfBirth);
} catch (Exception e) {
valid = false;
}
return valid;
}

For python version 2.x you can simply use
pip install pillow
But for python version 3.X you need to specify
(sudo) pip3 install pillow
when you enter pip in bash hit tab and you will see what options you have
This should be as simple as:
SELECT UserId, Value

Thank you all for your reply. I have got my script working with the module/ script written by Preston Landers way back in 2010. After two days of browsing the internet I could find the script as it was was deeply hidden in pywin32 mailing list. With this script it is easier to check if the user is admin and if not then ask for UAC/ admin right. It does provide output in separate windows to find out what the code is doing. Example on how to use the code also included in the script. For the benefit of all who all are looking for UAC on windows have a look at this code. I hope it helps someone looking for same solution. It can be used something like this from your main script:-
import admin
if not admin.isUserAdmin():
admin.runAsAdmin()

NPM shrinkwrap offers a nice solution to this problem. It allows us to override that version of a particular dependency of a particular sub-module.
Essentially, when you run npm install, npm will first look in your root directory to see whether a npm-shrinkwrap.json file exists. If it does, it will use this first to determine package dependencies, and then falling back to the normal process of working through the package.json files.
To create an npm-shrinkwrap.json, all you need to do is
npm shrinkwrap --dev
code:
{
"dependencies": {
"grunt-contrib-connect": {
"version": "0.3.0",
"from": "[email protected]",
"dependencies": {
"connect": {
"version": "2.8.1",
"from": "connect@~2.7.3"
}
}
}
}
}

You have not provided enough code to help You likely submit the form and reload the page OR you have an object on the page like an embedded PDF that steals the focus.
Here is the canonical plain javascript method of validating a form It can be improved with onubtrusive JS which will remove the inline script, but this is the starting point DEMO
function validate(formObj) {
document.getElementById("errorMsg").innerHTML = "";
var quantity = formObj.quantity;
if (isNaN(quantity)) {
quantity.value="";
quantity.focus();
document.getElementById("errorMsg").innerHTML = "Only numeric value is allowed";
return false;
}
return true; // allow submit
}
Here is the HTML
<form onsubmit="return validate(this)">
<input type="text" name="quantity" value="" />
<input type="submit" />
</form>
<span id="errorMsg"></span>
To complement Jakub's answer, if you have access to the remote git server in ssh, you can go into the git remote directory and set:
user@remote$ git config receive.denyNonFastforwards false
Then go back to your local repo, try again to do your commit with --force
:
user@local$ git push origin +master:master --force
And finally revert the server's setting in the original protected state:
user@remote$ git config receive.denyNonFastforwards true
In the second image it looks like you want the image to fill the box, but the example you created DOES keep the aspect ratio (the pets look normal, not slim or fat).
I have no clue if you photoshopped those images as example or the second one is "how it should be" as well (you said IS, while the first example you said "should")
Anyway, I have to assume:
If "the images are not resized keeping the aspect ration" and you show me an image which DOES keep the aspect ratio of the pixels, I have to assume you are trying to accomplish the aspect ratio of the "cropping" area (the inner of the green) WILE keeping the aspect ratio of the pixels. I.e. you want to fill the cell with the image, by enlarging and cropping the image.
If that's your problem, the code you provided does NOT reflect "your problem", but your starting example.
Given the previous two assumptions, what you need can't be accomplished with actual images if the height of the box is dynamic, but with background images. Either by using "background-size: contain" or these techniques (smart paddings in percents that limit the cropping or max sizes anywhere you want): http://fofwebdesign.co.uk/template/_testing/scale-img/scale-img.htm
The only way this is possible with images is if we FORGET about your second iimage, and the cells have a fixed height, and FORTUNATELY, judging by your sample images, the height stays the same!
So if your container's height doesn't change, and you want to keep your images square, you just have to set the max-height of the images to that known value (minus paddings or borders, depending on the box-sizing property of the cells)
Like this:
<div class="content">
<div class="row">
<div class="cell">
<img src="http://lorempixel.com/output/people-q-c-320-320-2.jpg"/>
</div>
<div class="cell">
<img src="http://lorempixel.com/output/people-q-c-320-320-7.jpg"/>
</div>
</div>
</div>
And the CSS:
.content {
background-color: green;
}
.row {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-box-orient: horizontal;
-moz-box-orient: horizontal;
box-orient: horizontal;
flex-direction: row;
-webkit-box-pack: center;
-moz-box-pack: center;
box-pack: center;
justify-content: center;
-webkit-box-align: center;
-moz-box-align: center;
box-align: center;
align-items: center;
}
.cell {
-webkit-box-flex: 1;
-moz-box-flex: 1;
box-flex: 1;
-webkit-flex: 1 1 auto;
flex: 1 1 auto;
padding: 10px;
border: solid 10px red;
text-align: center;
height: 300px;
display: flex;
align-items: center;
box-sizing: content-box;
}
img {
margin: auto;
width: 100%;
max-width: 300px;
max-height:100%
}
Your code is invalid (opening tags are instead of closing ones, so they output NESTED cells, not siblings, he used a SCREENSHOT of your images inside the faulty code, and the flex box is not holding the cells but both examples in a column (you setup "row" but the corrupt code nesting one cell inside the other resulted in a flex inside a flex, finally working as COLUMNS. I have no idea what you wanted to accomplish, and how you came up with that code, but I'm guessing what you want is this.
I added display: flex to the cells too, so the image gets centered (I think display: table
could have been used here as well with all this markup)
I think something like this:
btn.BackgroundImage = Properties.Resources.*Image_Identifier*;
Where *Image_Identifier*
is an identifier of the image in your resources.
You can use the following class. Just change zero to any default value you like. The solution was tested in Python 2.7.
class cDefaultDict(dict):
# dictionary that returns zero for missing keys
# keys with zero values are not stored
def __missing__(self,key):
return 0
def __setitem__(self, key, value):
if value==0:
if key in self: # returns zero anyway, so no need to store it
del self[key]
else:
dict.__setitem__(self, key, value)
you should examine the specification before using 'remainder' operator % :

Check permissions for you upload directory. You can find its path inside /etc/phpmyadmin/apache.conf
file.
In my case (Ubuntu 14.04) it was:
php_admin_value upload_tmp_dir /var/lib/phpmyadmin/tmp
So I checked permissions for /var/lib/phpmyadmin/tmp
and it turns out that the directory wasn't writable for my Apache user (which is by default www-data
). It could be the case especially if you changed your apache user like I do.
just had the same issue, but i could not find the conflicting branch anymore.
in my case the repo had and "foo" branch before, but not anymore and i tried to create and checkout "foo/bar" from remote. As i said "foo" did not exist anymore, but the issue persisted.
In the end, the branch "foo" was still in the .git/config file, after deleting it everything was alright :)
def bubble_sort(l):
for i in range(len(l) -1):
for j in range(len(l)-i-1):
if l[j] > l[j+1]:
l[j],l[j+1] = l[j+1], l[j]
return l
some times when you use android:windowSoftInputMode="stateAlwaysHidden"
in manifest activity or xml, that time it will lose keyboard focus. So first check for that property in your xml and manifest,if it is there just remove it. After add these option to manifest file in side activity android:windowSoftInputMode="adjustPan"
and add this property to listview in xml android:descendantFocusability="beforeDescendants"
Here's what we do:
Create a new connection, set the name, IP address and the appropriate port:
Set up authentication, if required
Optionally set up other available settings for SSL, SSH, etc.
Save and connect
For me this worked $ ? git branch -D -r origin/mybranch
Details
$ ? git branch -a | grep mybranch remotes/origin/mybranch
$ ? git branch -r | grep mybranch origin/mybranch
$ ? git branch develop * feature/pre-deployment
$ ? git push origin --delete mybranch error: unable to delete 'mybranch': remote ref does not exist error: failed to push some refs to '[email protected]:config/myrepo.git'
$ ? git branch -D -r origin/mybranch Deleted remote branch origin/mybranch (was 62c7421).
$ ? git branch -a | grep mybranch
$ ? git branch -r | grep mybranch
Use the change event on the file input.

You want the TimeSpan
struct:
TimeSpan diff = dateTime1 - dateTime2;
A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. The TimeSpan structure can also be used to represent the time of day, but only if the time is unrelated to a particular date.
There are various methods for getting the days, hours, minutes, seconds and milliseconds back from this structure.
If you are just interested in the difference then:
TimeSpan diff = Math.Abs(dateTime1 - dateTime2);
will give you the positive difference between the times regardless of the order.
If you have just got the time component but the times could be split by midnight then you need to add 24 hours to the span to get the actual difference:
TimeSpan diff = dateTime1 - dateTime2;
if (diff < 0)
{
diff = diff + TimeSpan.FromDays(1);
}
Here's my solution:
var content = "Visit https://wwww.google.com or watch this video: https://www.youtube.com/watch?v=0T4DQYgsazo and news at http://www.bbc.com";
content = replaceUrlsWithLinks(content, "http://");
content = replaceUrlsWithLinks(content, "https://");
function replaceUrlsWithLinks(content, protocol) {
var startPos = 0;
var s = 0;
while (s < content.length) {
startPos = content.indexOf(protocol, s);
if (startPos < 0)
return content;
let endPos = content.indexOf(" ", startPos + 1);
if (endPos < 0)
endPos = content.length;
let url = content.substr(startPos, endPos - startPos);
if (url.endsWith(".") || url.endsWith("?") || url.endsWith(",")) {
url = url.substr(0, url.length - 1);
endPos--;
}
if (ROOTNS.utils.stringsHelper.validUrl(url)) {
let link = "<a href='" + url + "'>" + url + "</a>";
content = content.substr(0, startPos) + link + content.substr(endPos);
s = startPos + link.length;
} else {
s = endPos + 1;
}
}
return content;
}
function validUrl(url) {
try {
new URL(url);
return true;
} catch (e) {
return false;
}
}
Modify the open_basedir
settings in your PHP configuration (See Runtime Configuration).
The open_basedir
setting is primarily used to prevent PHP scripts for a particular user from accessing files in another user's account. So usually, any files in your own account should be readable by your own scripts.
Example settings via .htaccess
if PHP runs as Apache module on a Linux system:
<DirectoryMatch "/home/sites/site81/">
php_admin_value open_basedir "/home/sites/site81/:/tmp/:/"
</DirectoryMatch>
Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
if you further face any difficulty then you need to provide more information about your web site and sql server .
I'd guess that speed is still the issue. Cross platform is going to be an issue isn't it since you don't know what 3d card is available when you write the code? Does java have anything to support auto discovery of 3d capabilities? And I'd guess that there are tools to ease porting a game between the wii, xbox, and ps3, but expensive I'll bet.
The ps3 has java, via the blue ray support. Check the bd-j site.
Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.
In the case the first arg is '-v', then do your conditional ps -ef
, else in all other cases throw the usage.
#!/bin/sh
case $1 in
'-v') if [ "$1" = -v ]; then
echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
fi;;
*) echo "usage: $0 [-v]"
exit 1;; #It is good practice to throw a code, hence allowing $? check
esac
If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.
#!/bin/sh
usage ()
{
echo "usage: $0 [-v]"
exit 1
}
unset arg_match
for arg in $*
do
case $arg in
'-v') if [ "$arg" = -v ]; then
echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
fi
arg_match=1;; # this is set, but could increment.
*) ;;
esac
done
if [ ! $arg_match ]
then
usage
fi
But, allow multiple occurrences of an argument is convenient to use in situations such as:
$ adduser -u:sam -s -f -u:bob -trace -verbose
We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:
$ adduser -u sam -s -f -u bob -trace -verbose
The mail function do not guarantee the actual delivery of mail. All it do is to pass the message to external program (usually sendmail). You need a properly configured SMTP server in order for this to work. Also keep in mind it does not support SMTP authentication. You may check out the PEAR::Mail library of SwiftMailer, both of them give you more options.
If you have some column in SELECT clause , how will it select it if there is several rows ? so yes , every column in SELECT clause should be in GROUP BY clause also , you can use aggregate functions in SELECT ...
you can have column in GROUP BY clause which is not in SELECT clause , but not otherwise
It works well in combination with zero-based indexing and len()
. For example, if you have 10 items in a list x
, they are numbered 0-9. range(len(x))
gives you 0-9.
Of course, people will tell you it's more Pythonic to do for item in x
or for index, item in enumerate(x)
rather than for i in range(len(x))
.
Slicing works that way too: foo[1:4]
is items 1-3 of foo
(keeping in mind that item 1 is actually the second item due to the zero-based indexing). For consistency, they should both work the same way.
I think of it as: "the first number you want, followed by the first number you don't want." If you want 1-10, the first number you don't want is 11, so it's range(1, 11)
.
If it becomes cumbersome in a particular application, it's easy enough to write a little helper function that adds 1 to the ending index and calls range()
.
