You can do this in single filter step:
requiredCars = cars.stream().filter(c -> c.getName() != null && c.getName().startsWith("M"));
If you don't want to call getName()
several times (for example, it's expensive call), you can do this:
requiredCars = cars.stream().filter(c -> {
String name = c.getName();
return name != null && name.startsWith("M");
});
Or in more sophisticated way:
requiredCars = cars.stream().filter(c ->
Optional.ofNullable(c.getName()).filter(name -> name.startsWith("M")).isPresent());
If you want to create a garage and fill it up with new cars that can be accessed later, use this code:
for (int i = 0; i < garage.length; i++)
garage[i] = new Car("argument");
Also, the cars are later accessed using:
garage[0];
garage[1];
garage[2];
etc.
Open Terminal

or add #!/usr/bin/env ruby
in the first of your program (script tell that this is executed using Ruby Interpreter)
Open Terminal

./program.rb
Based on Jim Lim's answer, I installed the GitHub Markdown gem. That included a script called gfm that takes a filename on the command line and writes the equivalent HTML to standard output. I modified that slightly to save the file to disk and then to open the standard browser with launchy:
#!/usr/bin/env ruby
HELP = <<-help
Usage: gfm [--readme | --plaintext] [<file>]
Convert a GitHub-Flavored Markdown file to HTML and write to standard output.
With no <file> or when <file> is '-', read Markdown source text from standard input.
With `--readme`, the files are parsed like README.md files in GitHub.com. By default,
the files are parsed with all the GFM extensions.
help
if ARGV.include?('--help')
puts HELP
exit 0
end
root = File.expand_path('../../', __FILE__)
$:.unshift File.expand_path('lib', root)
require 'github/markdown'
require 'tempfile'
require 'launchy'
mode = :gfm
mode = :markdown if ARGV.delete('--readme')
mode = :plaintext if ARGV.delete('--plaintext')
outputFilePath = File.join(Dir.tmpdir, File.basename(ARGF.path)) + ".html"
File.open(outputFilePath, "w") do |outputFile |
outputFile.write(GitHub::Markdown.to_html(ARGF.read, mode))
end
outputFileUri = 'file:///' + outputFilePath
Launchy.open(outputFileUri)
if you set NULL for all records try this:
UPDATE `table_name` SET `column_you_want_set_null`= NULL
OR just set NULL for special records use WHERE
UPDATE `table_name` SET `column_you_want_set_null`= NULL WHERE `column_name` = 'column_value'
You can do id by adding a class but never inline.
<style>.hover_pointer{cursor:pointer;}</style>
<div class="hover_pointer" style="font:bold 12pt Verdana;">Hello World</div>
2 lines but you can re-use the class everywhere.
Try this $('div').myFunction();
This should work
$(document).ready(function() {
$('#btnSun').click(function(){
myFunction();
});
function myFunction()
{
alert('hi');
}
you don't need to pass the entire encoded string to atob method, you need to split the encoded string and pass the required string to atob method

Just wanted to add a little more detail to the answers given. You can also use
sheet.Visible = False
to hide and
sheet.Visible = True
to unhide.
I had the same requirement - I just use this. User enters the number of days by which he/she wants to limit the calendar range to.
SELECT DAY, offset
FROM (SELECT to_char(SYSDATE, 'DD-MON-YYYY') AS DAY, 0 AS offset
FROM DUAL
UNION ALL
SELECT to_char(SYSDATE - rownum, 'DD-MON-YYYY'), rownum
FROM all_objects d)
where offset <= &No_of_days
I use the above result set as driving view in LEFT OUTER JOIN
with other views involving tables which have dates.
This can also happen if you don't have Modify permissions on the symbol cache directory configured in Tools, Options, Debugging, Symbols.
If you don't want to dock label in whole available area, just set SizeChanged event instead of TextChanged. Changing each letter will change the width property of label as well as its text when autosize property set to True. So, by the way you can use any formula to keep label centered in form.
private void lblReport_SizeChanged(object sender, EventArgs e)
{
lblReport.Left = (this.ClientSize.Width - lblReport.Size.Width) / 2;
}
Read open as
open for inheritance in other modules
I repeat open for inheritance in other modules. So an open class is open for subclassing in other modules that include the defining module. Open vars and functions are open for overriding in other modules. Its the least restrictive access level. It is as good as public access except that something that is public is closed for inheritance in other modules.
From Apple Docs:
Open access applies only to classes and class members, and it differs from public access as follows:
Classes with public access, or any more restrictive access level, can be subclassed only within the module where they’re defined.
Class members with public access, or any more restrictive access level, can be overridden by subclasses only within the module where they’re defined.
Open classes can be subclassed within the module where they’re defined, and within any module that imports the module where they’re defined.
Open class members can be overridden by subclasses within the module where they’re defined, and within any module that imports the module where they’re defined.
Yes - their performance characteristics differ significantly. It would probably be better to call them SortedList
and SortedTree
as that reflects the implementation more closely.
Look at the MSDN docs for each of them (SortedList
, SortedDictionary
) for details of the performance for different operations in different situtations. Here's a nice summary (from the SortedDictionary
docs):
The
SortedDictionary<TKey, TValue>
generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to theSortedList<TKey, TValue>
generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:
SortedList<TKey, TValue>
uses less memory thanSortedDictionary<TKey, TValue>
.
SortedDictionary<TKey, TValue>
has faster insertion and removal operations for unsorted data, O(log n) as opposed to O(n) forSortedList<TKey, TValue>
.If the list is populated all at once from sorted data,
SortedList<TKey, TValue>
is faster thanSortedDictionary<TKey, TValue>
.
(SortedList
actually maintains a sorted array, rather than using a tree. It still uses binary search to find elements.)
You need to set the height of html

y_desc = 'Dominance'
z_desc = 'Test'
desc = [x_desc, y_desc, z_desc]

col2_name = 'Reaction Time'
#You may need to group the variables together
#for n, (v_desc, v) in enumerate(zip(desc, variables)):
for n, v_desc, v in enumerate(zip(desc, variables)):
sh.write(n, 0, v_desc)
sh.write(n, 1, v)
n+=1
sh.write(n, 0, col1_name)
sh.write(n, 1, col2_name)
for m, e1 in enumerate(list1, n+1):
sh.write(m, 0, e1)
for m, e2 in enumerate(list2, n+1):
sh.write(m, 1, e2)
book.save(filename)

For some time now, you can also only rely on the data.table
package and its IDate
class plus associated functions (Check ?as.IDate()
). So, no need to additionally install lubridate
.
require(data.table)
a <- c("01/01/2009", "01/01/2010" , "01/01/2011")
year(as.IDate(a, '%d/%m/%Y')) # all data.table functions

This is the 2nd of two answers.
If you want to just strip all namespaces arbitrarily from a document during serialization, you can do this by implementing your own XmlWriter.
The easiest way is to derive from XmlTextWriter and override the StartElement method that emits namespaces. The StartElement method is invoked by the XmlSerializer when emitting any elements, including the root. By overriding the namespace for each element, and replacing it with the empty string, you've stripped the namespaces from the output.
public class NoNamespaceXmlWriter : XmlTextWriter
{
//Provide as many contructors as you need
public NoNamespaceXmlWriter(System.IO.TextWriter output)
: base(output) { Formatting= System.Xml.Formatting.Indented;}
public override void WriteStartDocument () { }
public override void WriteStartElement(string prefix, string localName, string ns)
{
base.WriteStartElement("", localName, "");
}
}
Suppose this is the type:
// explicitly specify a namespace for this type,
// to be used during XML serialization.
[XmlRoot(Namespace="urn:Abracadabra")]
public class MyTypeWithNamespaces
{
// private fields backing the properties
private int _Epoch;
private string _Label;
// explicitly define a distinct namespace for this element
[XmlElement(Namespace="urn:Whoohoo")]
public string Label
{
set { _Label= value; }
get { return _Label; }
}
// this property will be implicitly serialized to XML using the
// member name for the element name, and inheriting the namespace from
// the type.
public int Epoch
{
set { _Epoch= value; }
get { return _Epoch; }
}
}
Here's how you would use such a thing during serialization:
var o2= new MyTypeWithNamespaces { ..intializers.. };
var builder = new System.Text.StringBuilder();
using ( XmlWriter writer = new NoNamespaceXmlWriter(new System.IO.StringWriter(builder)))
{
s2.Serialize(writer, o2, ns2);
}
Console.WriteLine("{0}",builder.ToString());
The XmlTextWriter is sort of broken, though. According to the reference doc, when it writes it does not check for the following:
Invalid characters in attribute and element names.
Unicode characters that do not fit the specified encoding. If the Unicode characters do not fit the specified encoding, the XmlTextWriter does not escape the Unicode characters into character entities.
Duplicate attributes.
Characters in the DOCTYPE public identifier or system identifier.
These problems with XmlTextWriter have been around since v1.1 of the .NET Framework, and they will remain, for backward compatibility. If you have no concerns about those problems, then by all means use the XmlTextWriter. But most people would like a bit more reliability.
To get that, while still suppressing namespaces during serialization, instead of deriving from XmlTextWriter, define a concrete implementation of the abstract XmlWriter and its 24 methods.
An example is here:
public class XmlWriterWrapper : XmlWriter
{
protected XmlWriter writer;
public XmlWriterWrapper(XmlWriter baseWriter)
{
this.Writer = baseWriter;
}
public override void Close()
{
this.writer.Close();
}
protected override void Dispose(bool disposing)
{
((IDisposable) this.writer).Dispose();
}
public override void Flush()
{
this.writer.Flush();
}
public override string LookupPrefix(string ns)
{
return this.writer.LookupPrefix(ns);
}
public override void WriteBase64(byte[] buffer, int index, int count)
{
this.writer.WriteBase64(buffer, index, count);
}
public override void WriteCData(string text)
{
this.writer.WriteCData(text);
}
public override void WriteCharEntity(char ch)
{
this.writer.WriteCharEntity(ch);
}
public override void WriteChars(char[] buffer, int index, int count)
{
this.writer.WriteChars(buffer, index, count);
}
public override void WriteComment(string text)
{
this.writer.WriteComment(text);
}
public override void WriteDocType(string name, string pubid, string sysid, string subset)
{
this.writer.WriteDocType(name, pubid, sysid, subset);
}
public override void WriteEndAttribute()
{
this.writer.WriteEndAttribute();
}
public override void WriteEndDocument()
{
this.writer.WriteEndDocument();
}
public override void WriteEndElement()
{
this.writer.WriteEndElement();
}
public override void WriteEntityRef(string name)
{
this.writer.WriteEntityRef(name);
}
public override void WriteFullEndElement()
{
this.writer.WriteFullEndElement();
}
public override void WriteProcessingInstruction(string name, string text)
{
this.writer.WriteProcessingInstruction(name, text);
}
public override void WriteRaw(string data)
{
this.writer.WriteRaw(data);
}
public override void WriteRaw(char[] buffer, int index, int count)
{
this.writer.WriteRaw(buffer, index, count);
}
public override void WriteStartAttribute(string prefix, string localName, string ns)
{
this.writer.WriteStartAttribute(prefix, localName, ns);
}
public override void WriteStartDocument()
{
this.writer.WriteStartDocument();
}
public override void WriteStartDocument(bool standalone)
{
this.writer.WriteStartDocument(standalone);
}
public override void WriteStartElement(string prefix, string localName, string ns)
{
this.writer.WriteStartElement(prefix, localName, ns);
}
public override void WriteString(string text)
{
this.writer.WriteString(text);
}
public override void WriteSurrogateCharEntity(char lowChar, char highChar)
{
this.writer.WriteSurrogateCharEntity(lowChar, highChar);
}
public override void WriteValue(bool value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(DateTime value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(decimal value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(double value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(int value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(long value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(object value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(float value)
{
this.writer.WriteValue(value);
}
public override void WriteValue(string value)
{
this.writer.WriteValue(value);
}
public override void WriteWhitespace(string ws)
{
this.writer.WriteWhitespace(ws);
}
public override XmlWriterSettings Settings
{
get
{
return this.writer.Settings;
}
}
protected XmlWriter Writer
{
get
{
return this.writer;
}
set
{
this.writer = value;
}
}
public override System.Xml.WriteState WriteState
{
get
{
return this.writer.WriteState;
}
}
public override string XmlLang
{
get
{
return this.writer.XmlLang;
}
}
public override System.Xml.XmlSpace XmlSpace
{
get
{
return this.writer.XmlSpace;
}
}
}
Then, provide a derived class that overrides the StartElement method, as before:
public class NamespaceSupressingXmlWriter : XmlWriterWrapper
{
//Provide as many contructors as you need
public NamespaceSupressingXmlWriter(System.IO.TextWriter output)
: base(XmlWriter.Create(output)) { }
public NamespaceSupressingXmlWriter(XmlWriter output)
: base(XmlWriter.Create(output)) { }
public override void WriteStartElement(string prefix, string localName, string ns)
{
base.WriteStartElement("", localName, "");
}
}
And then use this writer like so:
var o2= new MyTypeWithNamespaces { ..intializers.. };
var builder = new System.Text.StringBuilder();
var settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent= true };
using ( XmlWriter innerWriter = XmlWriter.Create(builder, settings))
using ( XmlWriter writer = new NamespaceSupressingXmlWriter(innerWriter))
{
s2.Serialize(writer, o2, ns2);
}
Console.WriteLine("{0}",builder.ToString());

I've gotten same problem. The servers logs showed:
DEBUG: <-- origin: null
I've investigated that and it occurred that this is not populated when I've been calling from file from local drive. When I've copied file to the server and used it from server - the request worked perfectly fine
Try this :
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
var res = Find(html);
}
public static List<LinkItem> Find(string file)
{
List<LinkItem> list = new List<LinkItem>();
// 1.
// Find all matches in file.
MatchCollection m1 = Regex.Matches(file, @"(<a.*?>.*?</a>)",
RegexOptions.Singleline);
// 2.
// Loop over each match.
foreach (Match m in m1)
{
string value = m.Groups[1].Value;
LinkItem i = new LinkItem();
// 3.
// Get href attribute.
Match m2 = Regex.Match(value, @"href=\""(.*?)\""",
RegexOptions.Singleline);
if (m2.Success)
{
i.Href = m2.Groups[1].Value;
}
// 4.
// Remove inner tags from text.
string t = Regex.Replace(value, @"\s*<.*?>\s*", "",
RegexOptions.Singleline);
i.Text = t;
list.Add(i);
}
return list;
}
public struct LinkItem
{
public string Href;
public string Text;
public override string ToString()
{
return Href + "\n\t" + Text;
}
}
}
Input:
string html = "<a href=\"www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a> 2.<a href=\"http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a> ";
Result:
[0] = {www.aaa.xx/xx.zz?id=xxxx&name=xxxx}
[1] = {http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx}
Scraping HTML extracts important page elements. It has many legal uses for webmasters and ASP.NET developers. With the Regex type and WebClient, we implement screen scraping for HTML.
Another easy way:you can use a web browser
control for getting href
from tag a
,like this:(see my example)
public Form1()
{
InitializeComponent();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText = "<a href=\"www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"https://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"www.aaa.xx/xx.zz/xxx\" ....></a>";
}
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
List<string> href = new List<string>();
foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("a"))
{
href.Add(el.GetAttribute("href"));
}
}
amap.find
returns amap::end
when it does not find what you're looking for -- you're supposed to check for that.
Just to complete the answer (using the KeyEvent is the way to go) but up arrow is 38 and down arrow is 40 so:
else if (e.getKeyCode()==38)
{
//Up arrow key code
}
else if (e.getKeyCode()==40)
{
//down arrow key code
}
I was struggling with this question because I was looking for a way to do this in a bash script for OS X, hence /etc/passwd was out of the question, and my script was meant to be executed as root, therefore making the solutions invoking eval or bash -c dangerous as they allowed code injection into the variable specifying the username.
Here is what I found. It's simple and doesn't put a variable inside a subshell. However it does require the script to be ran by root as it sudos into the specified user account.
Presuming that $SOMEUSER contains a valid username:
echo "$(sudo -H -u "$SOMEUSER" -s -- "cd ~ && pwd")"
I hope this helps somebody!
The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.
When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.
Late answer, but hopefully worthwhile: The Poor Man's T-SQL Formatter is an open-source (free) T-SQL formatter with complete T-SQL batch/script support (any DDL, any DML), SSMS Plugin, command-line bulk formatter, and other options.
It's available for immediate/online use at http://poorsql.com, and just today graduated to "version 1.0" (it was in beta version for a few months), having just acquired support for MERGE
statements, OUTPUT
clauses, and other finicky stuff.
The SSMS Add-in allows you to set your own hotkey (default is Ctrl-K, Ctrl-F, to match Visual Studio), and formats the entire script or just the code you have selected/highlighted, if any. Output formatting is customizable.
In SSMS 2008 it combines nicely with the built-in intelli-sense, effectively providing more-or-less the same base functionality as Red Gate's SQL Prompt (SQL Prompt does, of course, have extra stuff, like snippets, quick object scripting, etc).
Feedback/feature requests are more than welcome, please give it a whirl if you get the chance!
Disclosure: This is probably obvious already but I wrote this library/tool/site, so this answer is also shameless self-promotion :)
I figured out myself.
cmp
calls ComputeBetasAndNuHat
which returns a list which has objective

So I can change the function cmp
to get this value.

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).
Typical symptoms:
[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100
[root@host /]# netstat -plant | grep 25
tcp 0 0 :::25 :::* LISTEN 1082/exim
If this happens, make sure that you don't have two entries for localhost
in /etc/hosts
with different IP addresses, like this (bad) example:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
To avoid confusion, make sure you only have one entry for localhost
, preferably an IPv4 address, like this:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4.localdomain4 localhost4
::1 localhost6 localhost6.localdomain6
On windows you can inspect the login "authorizations" (auths) by looking at this file: [USER_HOME_DIR].docker\config.json
Example: c:\USERS\YOUR_USERANME.docker\config.json
It will look something like this for windows credentials
{
"auths": {
"HOST_NAME_HERE": {},
"https://index.docker.io/v1/": {}
},
"HttpHeaders": {
"User-Agent": "Docker-Client/18.09.0 (windows)"
},
"credsStore": "wincred",
"stackOrchestrator": "swarm"
}
There is another approach, you can narrow the return type when you override a method. In each subclass you would have to override callFriend to return that subclass. The cost would be the multiple declarations of callFriend, but you could isolate the common parts to a method called internally. This seems a lot simpler to me than the solutions mentioned above, and does not need an extra argument to determine the return type.
swal({
title: "Are you sure?",
text: "You will not be able to recover this imaginary file!",
type: "warning",
showCancelButton: true,
confirmButtonColor: '#DD6B55',
confirmButtonText: 'Yes, I am sure!',
cancelButtonText: "No, cancel it!"
}).then(
function () { /*Your Code Here*/ },
function () { return false; });
If you wish to escape HTML in a URL:
This is probably NOT what the OP wanted (the question doesn't clearly indicate in which context the escaping is meant to be used), but Python's native library urllib has a method to escape HTML entities that need to be included in a URL safely.
The following is an example:
#!/usr/bin/python
from urllib import quote
x = '+<>^&'
print quote(x) # prints '%2B%3C%3E%5E%26'
Close the modal with universal $().hide()
method:
$('#product-options').hide();
use your jsonsimpleobject direclty like below
JSONObject unitsObj = parser.parse(new FileReader("file.json");
you can use String format to include variables within strings
i use this code to include 2 variable in string:
String myString = String.format("this is my string %s %2d", variable1Name, variable2Name);
You can do this:
<img src="your image" style="transform:rotate(90deg);">
it is much easier.
I add the changes directly to my virtualhost instead the global config of nginx, like this:
server {
client_max_body_size 100M;
...
}
And then I change the params in php.ini, like the comments above:
max_input_time = 24000
max_execution_time = 24000
upload_max_filesize = 12000M
post_max_size = 24000M
memory_limit = 12000M
and what you can not forget is to restart nginx and php-fpm, in centos 7 is like this:
systemctl restart nginx
systemctl restart php-fpm
Try this:
git rev-parse --short HEAD
The command git rev-parse
can do a remarkable number of different things, so you'd need to go through the documentation very carefully to spot that though.
Well, like the guy (@user2982122) mentioned but instead of File go to Code -> Preferences -> Settings, then look for Quote, select Prettier and check both boxes
In ES2015 a.k.a ES6 version of JavaScript, a new datatype called Map

check this reference for more info.
In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:
make sure your API is sending the Content-Type
header to tell the client to expect a JSON response:

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.
If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController
with an add()
action/method.
There are a few starting point projects for RESTful APIs on GitHub that are worth a look.
I solved both the errors (-19,0) and (-38,0) , by creating a new object of MediaPlayer every time before playing and releasing it after that.
Before :
void play(int resourceID) {
if (getActivity() != null) {
//Using the same object - Problem persists
player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
After:
void play(int resourceID) {
if (getActivity() != null) {
//Problem Solved
//Creating new MediaPlayer object every time and releasing it after completion
final MediaPlayer player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
I had the same problems. I had to change file rights. Unmark "read only" in their properties.
Step 1: Hook your HTML number input box to an onchange event
myHTMLNumberInput.onchange = setTwoNumberDecimal;
or in the HTML code
<input type="number" onchange="setTwoNumberDecimal" min="0" max="10" step="0.25" value="0.00" />
Step 2: Write the setTwoDecimalPlace
method
function setTwoNumberDecimal(event) {
this.value = parseFloat(this.value).toFixed(2);
}
You can alter the number of decimal places by varying the value passed into the toFixed()
method. See MDN docs.
toFixed(2); // 2 decimal places
toFixed(4); // 4 decimal places
toFixed(0); // integer
What you are (trying to do)/doing in your snippet is to return a local variable from the function, which is not at all recommended - nor is it allowed according to the standard.
If you'd like to create a int[6][6]
from your function you'll either have to allocate memory for it on the free-store (ie. using new T/malloc or similar function), or pass in an already allocated piece of memory to MakeGridOfCounts
.
I had the same issue and no solution above worked for me and it sort of felt like guess work thereafter. However, wrapping my code which creates the object in a setTimeout
function did the trick for me.
setTimeout(function() {
var myObj = xyz; //some code for creation of complex object like above
console.log(myObj); // this works
console.log(myObj.propertyName); // this works too
});
The first matches any number of digits within your string (allows other characters too, i.e.: "039330a29"). The second allows only 45 digits (and not less). So just take the better from both:
^\d{1,45}$
where \d
is the same like [0-9]
.
If you are trying to host your Laravel app on a shared hosting, this may help you.
Hosting Laravel on shared hosting #1
Hosting Laravel on shared hosting #2
If you want PHP 5.4 add this line to your .htaccess
file or call your hosting provider.
AddType application/x-httpd-php54 .php
Try this .{3,} this will match any characher except new line (\n)
Perhaps the easiest way is to just create a new repository with current state of the working copy. If you want to keep all the commit messages you could first do git log > original.log
and then edit that for your initial commit message in the new repository:
rm -rf .git
git init
git add .
git commit
or
git log > original.log
# edit original.log as desired
rm -rf .git
git init
git add .
git commit -F original.log
I have a solution for GSuite accounts that doesnt have the "@gmail.com" sufix. Also I think it will work for GSuite accounts with the @gmail.com but havent tried it. First you should have the privileges to change the option "allos¿w less secure app" for your GSuite account. If you have the privileges (you can check in account settings->security) then you have to deactivate "two step factor authentication" go to the end of the page and set to "yes" for allow less secure applications. That's all. If you dont have privileges to change those options the solution for this thread will not work. Check https://support.google.com/a/answer/6260879?hl=en to make changes to "allow less..." option.
Dirkgently gives an excellent description of integer division in C99, but you should also know that in C89 integer division with a negative operand has an implementation-defined direction.
From the ANSI C draft (3.3.5):
If either operand is negative, whether the result of the / operator is the largest integer less than the algebraic quotient or the smallest integer greater than the algebraic quotient is implementation-defined, as is the sign of the result of the % operator. If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a.
So watch out with negative numbers when you are stuck with a C89 compiler.
It's a fun fact that C99 chose truncation towards zero because that was how FORTRAN did it. See this message on comp.std.c.
You might want to replace <br/>
and </p>
tags with newlines before stripping the HTML to prevent it becoming an illegible mess as Tim suggests.
The only way I can think of removing HTML tags but leaving non-HTML between angle brackets would be check against a list of HTML tags. Something along these lines...
replaceAll("\\<[\s]*tag[^>]*>","")
Then HTML-decode special characters such as &
. The result should not be considered to be sanitized.
reg
and wire
specify how the object will be assigned and are therefore only meaningful for outputs.
If you plan to assign your output in sequential code,such as within an always
block, declare it as a reg
(which really is a misnomer for "variable" in Verilog). Otherwise, it should be a wire
, which is also the default.
Strings are immutable objects so you can copy them just coping the reference to them, because the object referenced can't change ...
So you can copy as in your first example without any problem :
String s = "hello";
String backup_of_s = s;
s = "bye";
My question is when should a use a double and when should I use a decimal type?
decimal
for when you work with values in the range of 10^(+/-28) and where you have expectations about the behaviour based on base 10 representations - basically money.
double
for when you need relative accuracy (i.e. losing precision in the trailing digits on large values is not a problem) across wildly different magnitudes - double
covers more than 10^(+/-300). Scientific calculations are the best example here.
which type is suitable for money computations?
decimal, decimal, decimal
Accept no substitutes.
The most important factor is that double
, being implemented as a binary fraction, cannot accurately represent many decimal
fractions (like 0.1) at all and its overall number of digits is smaller since it is 64-bit wide vs. 128-bit for decimal
. Finally, financial applications often have to follow specific rounding modes (sometimes mandated by law). decimal
supports these; double
does not.
This picture should give you the idea about the context in which the words breadth and depth are used.
Depth-first search algorithm acts as if it wants to get as far away from the starting point as quickly as possible.
It generally uses a Stack
to remember where it should go when it reaches a dead end.
Rules to follow: Push first vertex A on to the Stack
Java code:
public void searchDepthFirst() {
// Begin at vertex 0 (A)
vertexList[0].wasVisited = true;
displayVertex(0);
stack.push(0);
while (!stack.isEmpty()) {
int adjacentVertex = getAdjacentUnvisitedVertex(stack.peek());
// If no such vertex
if (adjacentVertex == -1) {
stack.pop();
} else {
vertexList[adjacentVertex].wasVisited = true;
// Do something
stack.push(adjacentVertex);
}
}
// Stack is empty, so we're done, reset flags
for (int j = 0; j < nVerts; j++)
vertexList[j].wasVisited = false;
}
Applications: Depth-first searches are often used in simulations of games (and game-like situations in the real world). In a typical game you can choose one of several possible actions. Each choice leads to further choices, each of which leads to further choices, and so on into an ever-expanding tree-shaped graph of possibilities.
Queue
.Java code:
public void searchBreadthFirst() {
vertexList[0].wasVisited = true;
displayVertex(0);
queue.insert(0);
int v2;
while (!queue.isEmpty()) {
int v1 = queue.remove();
// Until it has no unvisited neighbors, get one
while ((v2 = getAdjUnvisitedVertex(v1)) != -1) {
vertexList[v2].wasVisited = true;
// Do something
queue.insert(v2);
}
}
// Queue is empty, so we're done, reset flags
for (int j = 0; j < nVerts; j++)
vertexList[j].wasVisited = false;
}
Applications: Breadth-first search first finds all the vertices that are one edge away from the starting point, then all the vertices that are two edges away, and so on. This is useful if you’re trying to find the shortest path from the starting vertex to a given vertex.
Hopefully that should be enough for understanding the Breadth-First and Depth-First searches. For further reading I would recommend the Graphs chapter from an excellent data structures book by Robert Lafore.
Even though your JDK in eclipse is 1.7, you need to make sure eclipse compilance level also set to 1.7. You can check compilance level--> Window-->Preferences--> Java--Compiler--compilance level.
Unsupported major minor error happens in cases where compilance level doesn't match with runtime.
I have used Newtonsoft JSON.NET (Documentation) It allows you to create a class / object, populate the fields, and serialize as JSON.
public class ReturnData
{
public int totalCount { get; set; }
public List<ExceptionReport> reports { get; set; }
}
public class ExceptionReport
{
public int reportId { get; set; }
public string message { get; set; }
}
string json = JsonConvert.SerializeObject(myReturnData);
Update 23 March'15 :
Official multiple SIM API is available now from Android 5.1 onwards
Other possible option :
You can use Java reflection to get both IMEI numbers.
Using these IMEI numbers you can check whether the phone is a DUAL SIM or not.
Try following activity :
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyInfo telephonyInfo = TelephonyInfo.getInstance(this);
String imeiSIM1 = telephonyInfo.getImsiSIM1();
String imeiSIM2 = telephonyInfo.getImsiSIM2();
boolean isSIM1Ready = telephonyInfo.isSIM1Ready();
boolean isSIM2Ready = telephonyInfo.isSIM2Ready();
boolean isDualSIM = telephonyInfo.isDualSIM();
TextView tv = (TextView) findViewById(R.id.tv);
tv.setText(" IME1 : " + imeiSIM1 + "\n" +
" IME2 : " + imeiSIM2 + "\n" +
" IS DUAL SIM : " + isDualSIM + "\n" +
" IS SIM1 READY : " + isSIM1Ready + "\n" +
" IS SIM2 READY : " + isSIM2Ready + "\n");
}
}
And here is TelephonyInfo.java
:
import java.lang.reflect.Method;
import android.content.Context;

private static final long serialVersionUID = -996812356902545308L;
public GeminiMethodNotFoundException(String info) {

}
}
Edit :
Getting access of methods like "getDeviceIdGemini" for other SIM slot's detail has prediction that method exist.
If that method's name doesn't match with one given by device manufacturer than it will not work. You have to find corresponding method name for those devices.
Finding method names for other manufacturers can be done using Java reflection as follows :
public static void printTelephonyManagerMethodNamesForThisDevice(Context context) {
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> telephonyClass;
try {
telephonyClass = Class.forName(telephony.getClass().getName());
Method[] methods = telephonyClass.getMethods();
for (int idx = 0; idx < methods.length; idx++) {
System.out.println("\n" + methods[idx] + " declared by " + methods[idx].getDeclaringClass());
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
EDIT :
As Seetha pointed out in her comment :
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getDeviceIdDs", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceIdDs", 1);
It is working for her. She was successful in getting two IMEI numbers for both the SIM in Samsung Duos device.
Add <uses-permission android:name="android.permission.READ_PHONE_STATE" />
EDIT 2 :
The method used for retrieving data is for Lenovo A319 and other phones by that manufacture (Credit Maher Abuthraa):
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getSimSerialNumberGemini", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getSimSerialNumberGemini", 1);
EXAMPLE:- Although it is not very common that we find ourselves in need of a 302 redirect, this option can be very useful in some cases. These are the most frequent cases:
A redirect 302 is a code that tells visitors of a specific URL that the page has been moved temporarily, directing them directly to the new location.
In other words, redirect 302 is activated when Google robots or other search engines request to load a specific page. At that moment, thanks to this redirection, the server returns an automatic response indicating a new URL.
In this way errors and annoyances are avoided both to search engines and users, guaranteeing smooth navigation.

Is there any reason not to use threads? You can use the threading
class.
Instead of finished()
function use the isAlive()
. The result()
function could join()
the thread and retrieve the result. And, if you can, override the run()
and __init__
functions to call the function specified in the constructor and save the value somewhere to the instance of the class.
Model Class:
public class ToDoModel implements Comparable<ToDoModel> {
private String id;
private Date taskDate;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Date getTaskDate() {
return taskDate;
}
public void setTaskDate(Date taskDate) {
this.taskDate = taskDate;
}
@Override
public int compareTo(ToDoModel another) {
return getTaskDate().compareTo(another.getTaskDate());
}
}
Now set data in ArrayList
for (int i = 0; i < your_array_length; i++) {
ToDoModel tm = new ToDoModel();
tm.setId(your_id);
tm.setTaskDate(your_date);
mArrayList.add(tm);
}
Now Sort ArrayList
Collections.sort(toDoList);
Summary: It will sort your data datewise
You need to set the flags after the project
command in your CMakeLists.txt.
Also, if you're calling include(${QT_USE_FILE})
or add_definitions(${QT_DEFINITIONS})
, you should include these set
commands after the Qt ones since these would append further flags. If that is the case, you maybe just want to append your flags to the Qt ones, so change to e.g.
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O0 -ggdb")
C++17
simplified this a bit more with an If statement with initializer
.
This way you can have your cake and eat it too.
if ( auto it{ m.find( "key" ) }; it != std::end( m ) )
{
// Use `structured binding` to get the key
// and value.
auto[ key, value ] { *it };
// Grab either the key or value stored in the pair.
// The key is stored in the 'first' variable and
// the 'value' is stored in the second.
auto mkey{ it->first };
auto mvalue{ it->second };
// That or just grab the entire pair pointed
// to by the iterator.
auto pair{ *it };
}
else
{
// Key was not found..
}
You can use EmbeddedProfiler, it's free for both Linux and Windwos.
The profiler is intrusive (by functionality) but it doens't require any code modifications. Just add a specific compiler flag (-finstrument-functios for gcc/MinGW or /GH for MSVC) and link the profiler's library. It can provide you a full call tree or just a funciton list. It has it's own analyzer GUI.
The -m
option is probably what you're looking for:
grep -m 10 PATTERN [FILE]
From man grep
:
-m NUM, --max-count=NUM
Stop reading a file after NUM matching lines. If the input is
standard input from a regular file, and NUM matching lines are
output, grep ensures that the standard input is positioned to
just after the last matching line before exiting, regardless of
the presence of trailing context lines. This enables a calling
process to resume a search.
Note: grep stops reading the file once the specified number of matches have been found!
I've discovered in Excel 2007, if the results are a Table from an embedded query, the ss.000 does not work. I can paste the query results (from SQL Server Management Studio), and format the time just fine. But when I embed the query as a Data Connection in Excel, the format always gives .000 as the milliseconds.
As an alternative to using git config --global http.proxy address:port
, you can set the proxy on the command line:
git -c "http.proxy=address:port" clone https://...
The advantage is the proxy is not persistently set. Under Bash you might set an alias:
alias git-proxy='git -c "http.proxy=address:port"'
You can use include=FALSE
to exclude everything in a chunk.
```{r include=FALSE}
source("C:/Rscripts/source.R")
```
If you only want to suppress messages, use message=FALSE
instead:
```{r message=FALSE}
source("C:/Rscripts/source.R")
```
Good question. At the time it was asked, a universally-implemented way to do "combinator rooted queries" (as John Resig called them) did not exist.
Now the :scope pseudo-class has been introduced. It is not supported on [pre-Chrominum] versions of Edge or IE, but has been supported by Safari for a few years already. Using that, your code could become:
let myDiv = getElementById("myDiv");
myDiv.querySelectorAll(":scope > .foo");
Note that in some cases you can also skip .querySelectorAll
and use other good old-fashioned DOM API features. For example, instead of myDiv.querySelectorAll(":scope > *")
you could just write myDiv.children
, for example.
Otherwise if you can't yet rely on :scope
, I can't think of another way to handle your situation without adding more custom filter logic (e.g. find myDiv.getElementsByClassName("foo")
whose .parentNode === myDiv
), and obviously not ideal if you're trying to support one code path that really just wants to take an arbitrary selector string as input and a list of matches as output! But if like me you ended up asking this question simply because you got stuck thinking "all you had was a hammer" don't forget there are a variety of other tools the DOM offers too.
Instead of rotating the text, would it work to have it written "top to bottom?"
Like this:
S
O
M
E
T
E
X
T
I think that would be a lot easier - you can pick a string of text apart and insert a line break after each character.
This could be done via JavaScript in the browser like this:
"SOME TEXT".split("").join("\n")
... or you could do it server-side, so it wouldn't depend on the client's JS capabilities. (I assume that's what you mean by "portable?")
Also the user doesn't have to turn his/her head sideways to read it. :)
This thread is about doing this with jQuery.
An alternative is to use the maven shade plugin to build an uber-jar

Definitely late to the party; anyway, for those interested, picking up on Lan's mention of HTML5 canvas, you can use gRaphaël Charting which has a MIT License (instead of HighCharts dual license). It's not Bootstrap-specific either, so it's more of a general suggestion.
I have to admit that HighCharts demos seem very pretty, and I have to warn that gRaphaël is quite hard to understand before becoming proficient with it. Anyway you can easily add nice features to your gRaphaël charts (say, tooltips or zooming effects), so it may be worth the effort.
Following answer may help you
perform your date ordering by your date identifier but use to_char() function in select clause and use some other identifier in select clause for date
e.g.
SELECT TO_CHAR(DISPDATE1,'DD/MM/YYYY') AS DISPDATE,
SUM(APPLCOUNT) AS APPLIED,
SUM(CONFCOUNT) AS CONFIRMED
FROM
(
SELECT COUNT(ID) AS APPLCOUNT,
0 AS CONFCOUNT,
STUDENT.APPLIED_ON AS DISPDATE1
FROM STUDENT
WHERE STUDENT.ID = P_ID
GROUP BY STUDENT.APPLIED_ON
UNION
SELECT 0 AS APPLCOUNT,
COUNT(ID) AS CONFCOUNT,
STUDENT.CONFIRMED_ON AS DISPDATE1
FROM STUDENT
WHERE STUDENT.ID = P_ID
GROUP BY STUDENT.CONFIRMED_ON
)
GROUP BY DISPDATE1
ORDER BY DISPDATE1;
Angular routes watch the browser's location, so simply using window.history.back()
on clicking something would work.
HTML:
<div class="nav-header" ng-click="doTheBack()">Reverse!</div>
JS:
$scope.doTheBack = function() {
window.history.back();
};
I usually create a global function called '$back' on my app controller, which I usually put on the body tag.
angular.module('myApp').controller('AppCtrl', ['$scope', function($scope) {
$scope.$back = function() {
window.history.back();
};
}]);
Then anywhere in my app I can just do <a ng-click="$back()">Back</a>
(If you want it to be more testable, inject the $window service into your controller and use $window.history.back()
).
If you are using php can do:
<script src="js/myscript.js?rev=<?php echo time();?>"
type="text/javascript"></script>
parentFragmentManager.apply {
val f = this@MyFragment
beginTransaction().hide(f).remove(f).commit()
}
This works fine for me:
while True:
answer = input('Do you want to continue?:')
if answer.lower().startswith("y"):
print("ok, carry on then")
elif answer.lower().startswith("n"):
print("sayonara, Robocop")
exit()
edit: use input
in python 3.2 instead of raw_input
The typical solution to this is to write your own function to clone an object. If you are able to provide copy constructors and copy assignement operators, this may be as far as you need to go.
class Foo
{
public:
Foo();
Foo(const Foo& rhs) { /* copy construction from rhs*/ }
Foo& operator=(const Foo& rhs) {};
};
// ...
Foo orig;
Foo copy = orig; // clones orig if implemented correctly
Sometimes it is beneficial to provide an explicit clone()
method, especially for polymorphic classes.
class Interface
{
public:
virtual Interface* clone() const = 0;
};
class Foo : public Interface
{
public:
Interface* clone() const { return new Foo(*this); }
};
class Bar : public Interface
{
public:
Interface* clone() const { return new Bar(*this); }
};
Interface* my_foo = /* somehow construct either a Foo or a Bar */;
Interface* copy = my_foo->clone();
EDIT: Since Stack
has no member variables, there's nothing to do in the copy constructor or copy assignment operator to initialize Stack
's members from the so-called "right hand side" (rhs
). However, you still need to ensure that any base classes are given the opportunity to initialize their members.
You do this by calling the base class:
Stack(const Stack& rhs)
: List(rhs) // calls copy ctor of List class
{
}
Stack& operator=(const Stack& rhs)
{
List::operator=(rhs);

Presumably from this site:
Internal Fragmentation Internal fragmentation occurs when the memory allocator leaves extra space empty inside of a block of memory that has been allocated for a client. This usually happens because the processor’s design stipulates that memory must be cut into blocks of certain sizes -- for example, blocks may be required to be evenly be divided by four, eight or 16 bytes. When this occurs, a client that needs 57 bytes of memory, for example, may be allocated a block that contains 60 bytes, or even 64. The extra bytes that the client doesn’t need go to waste, and over time these tiny chunks of unused memory can build up and create large quantities of memory that can’t be put to use by the allocator. Because all of these useless bytes are inside larger memory blocks, the fragmentation is considered internal.
External Fragmentation External fragmentation happens when the memory allocator leaves sections of unused memory blocks between portions of allocated memory. For example, if several memory blocks are allocated in a continuous line but one of the middle blocks in the line is freed (perhaps because the process that was using that block of memory stopped running), the free block is fragmented. The block is still available for use by the allocator later if there’s a need for memory that fits in that block, but the block is now unusable for larger memory needs. It cannot be lumped back in with the total free memory available to the system, as total memory must be contiguous for it to be useable for larger tasks. In this way, entire sections of free memory can end up isolated from the whole that are often too small for significant use, which creates an overall reduction of free memory that over time can lead to a lack of available memory for key tasks.
You can try restful.js, a framework-agnostic RESTful client, using a syntax similar to the popular Restangular.
POJO : It is a java file(class) which doesn't extend or implement any other java file(class).
Bean: It is a java file(class) in which all variables are private, methods are public and appropriate getters and setters are used for accessing variables.
Normal class: It is a java file(class) which may consist of public/private/default/protected variables and which may or may not extend or implement another java file(class).

Add XAttribute
in the constructor of the XElement
, like
new XElement("Conn", new XAttribute("Server", comboBox1.Text));
You can also add multiple attributes or elements via the constructor
new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));
or you can use the Add-Method of the XElement
to add attributes
XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);
When using spark.read.csv
, I find that using the options escape='"'
and multiLine=True
provide the most consistent solution to the CSV standard, and in my experience works the best with CSV files exported from Google Sheets.
That is,
#set inferSchema=False to read everything as string
df = spark.read.csv("myData.csv", escape='"', multiLine=True,
inferSchema=False, header=True)
The low_memory
option is not properly deprecated, but it should be, since it does not actually do anything differently[source]
The reason you get this low_memory
warning is because guessing dtypes for each column is very memory demanding. Pandas tries to determine what dtype to set by analyzing the data in each column.
Pandas can only determine what dtype a column should have once the whole file is read. This means nothing can really be parsed before the whole file is read unless you risk having to change the dtype of that column when you read the last value.
Consider the example of one file which has a column called user_id. It contains 10 million rows where the user_id is always numbers. Since pandas cannot know it is only numbers, it will probably keep it as the original strings until it has read the whole file.
adding
dtype={'user_id': int}
to the pd.read_csv()
call will make pandas know when it starts reading the file, that this is only integers.
Also worth noting is that if the last line in the file would have "foobar"
written in the user_id
column, the loading would crash if the above dtype was specified.
import pandas as pd
try:
from StringIO import StringIO
except ImportError:
from io import StringIO
csvdata = """user_id,username
1,Alice
3,Bob
foobar,Caesar"""
sio = StringIO(csvdata)
pd.read_csv(sio, dtype={"user_id": int, "username": "string"})
ValueError: invalid literal for long() with base 10: 'foobar'
dtypes are typically a numpy thing, read more about them here: http://docs.scipy.org/doc/numpy/reference/generated/numpy.dtype.html
We have access to numpy dtypes: float, int, bool, timedelta64[ns] and datetime64[ns]. Note that the numpy date/time dtypes are not time zone aware.
Pandas extends this set of dtypes with its own:
'datetime64[ns, ]' Which is a time zone aware timestamp.
'category' which is essentially an enum (strings represented by integer keys to save
'period[]' Not to be confused with a timedelta, these objects are actually anchored to specific time periods
'Sparse', 'Sparse[int]', 'Sparse[float]' is for sparse data or 'Data that has a lot of holes in it' Instead of saving the NaN or None in the dataframe it omits the objects, saving space.
'Interval' is a topic of its own but its main use is for indexing. See more here
'Int8', 'Int16', 'Int32', 'Int64', 'UInt8', 'UInt16', 'UInt32', 'UInt64' are all pandas specific integers that are nullable, unlike the numpy variant.
'string' is a specific dtype for working with string data and gives access to the .str
attribute on the series.
'boolean' is like the numpy 'bool' but it also supports missing data.
Read the complete reference here:
Setting dtype=object
will silence the above warning, but will not make it more memory efficient, only process efficient if anything.
Setting dtype=unicode
will not do anything, since to numpy, a unicode
is represented as object
.
@sparrow correctly points out the usage of converters to avoid pandas blowing up when encountering 'foobar'
in a column specified as int
. I would like to add that converters are really heavy and inefficient to use in pandas and should be used as a last resort. This is because the read_csv process is a single process.
CSV files can be processed line by line and thus can be processed by multiple converters in parallel more efficiently by simply cutting the file into segments and running multiple processes, something that pandas does not support. But this is a different story.
Whether or not the "date" '0000-00-00" is a valid "date" is irrelevant to the question. "Just change the database" is seldom a viable solution.
Facts:
So, if I "just change the database", thousands of lines of PHP code will break.
Java programmers need to accept the MySQL zero-date and they need to put a zero date back into the database, when other languages rely on this "feature".
A programmer connecting to MySQL needs to handle null and 0000-00-00 as well as valid dates. Changing 0000-00-00 to null is not a viable option, because then you can no longer determine if the date was expected to be 0000-00-00 for writing back to the database.
For 0000-00-00, I suggest checking the date value as a string, then changing it to ("y",1), or ("yyyy-MM-dd",0001-01-01), or into any invalid MySQL date (less than year 1000, iirc). MySQL has another "feature": low dates are automatically converted to 0000-00-00.
I realize my suggestion is a kludge. But so is MySQL's date handling. And two kludges don't make it right. The fact of the matter is, many programmers will have to handle MySQL zero-dates forever.
In case you want to be lazier:
#syntax lambda x : (false,true)[Condition]
In your case:
rate = lambda(T) : (400*exp(-T),200*exp(-T))[T>200]
Do you mean you only want the alphabetic characters and not the digits? So you want "quality" as a result? You can use Char.IsLetter or Char.IsDigit to filter them out one by one.
string s = "9quali52ty3";
StringBuilder result = new StringBuilder();
foreach(char c in s)
{
if (Char.IsLetter(c))
result.Add(c);
}
Console.WriteLine(result); // quality
Short function. PHP 5.3 and up. Can take optional third param of any date format that strtotime can understand. Automatically reverses direction if end < start.
function getDatesFromRange($start, $end, $format='Y-m-d') {

return date($format, $timestamp);
},
range(strtotime($start) + ($start < $end ? 4000 : 8000), strtotime($end) + ($start < $end ? 8000 : 4000), 86400));

print_r(getDatesFromRange( '2016-7-28','2016-8-2' ));
print_r(getDatesFromRange( '2016-8-2','2016-7-28' ));

Many ways this can be achieved.
Simple approach should be taking Substring
of an input string.
var result = input.Substring(input.Length - 3);
Another approach using Regular Expression
to extract last 3 characters.
var result = Regex.Match(input,@"(.{3})\s*$");
Working Demo
Environment Entries specified by <Environment>
markup are JNDI, accessible using InitialContext.lookup under java:/comp/env
. You can specify environment properties to the JNDI by using the environment parameter to the InitialContext constructor and application resource files.
System.getEnv()
is about system environment variables of the tomcat process itself.
To set an environment variable using bash command :
export TOMCAT_OPTS=-Dmy.bar=foo
and start the Tomcat :
./startup.sh
To retrieve the value of System property bar
use System.getProperty()
. System.getEnv()
can be used to retrieve the environment variable i.e. TOMCAT_OPTS
.
I've found out the solution! Thanks to Firebug ;)
//"markers" is an array that I declared which contains all the marker of the map
//"i" is the index of the marker in the array that I want to trigger the OnClick event
//V2 version is:
GEvent.trigger(markers[i], 'click');
//V3 version is:
google.maps.event.trigger(markers[i], 'click');
I'm using rc.4 and this method works for ES2015(ES6):
import {DomSanitizationService} from '@angular/platform-browser';
@Component({
templateUrl: 'build/pages/veeu/veeu.html'
})
export class VeeUPage {
static get parameters() {
return [NavController, App, MenuController, DomSanitizationService];
}
constructor(nav, app, menu, sanitizer) {
this.app = app;
this.nav = nav;
this.menu = menu;
this.sanitizer = sanitizer;
}
photoURL() {
return this.sanitizer.bypassSecurityTrustUrl(this.mediaItems[1].url);
}
}
In the HTML:
<iframe [src]='photoURL()' width="640" height="360" frameborder="0"
webkitallowfullscreen mozallowfullscreen allowfullscreen>
</iframe>
Using a function will ensure that the value doesn't change after you sanitize it. Also be aware that the sanitization function you use depends on the context.
For images, bypassSecurityTrustUrl
will work but for other uses you need to refer to the documentation:
https://angular.io/docs/ts/latest/api/platform-browser/index/DomSanitizer-class.html
The field identifiers are indeed C initializer syntax. In C++ just give the values in the correct order without the field names. Unfortunately this means you need to give them all (actually you can omit trailing zero-valued fields and the result will be the same):
address temp_address = { 0, 0, "Hamilton", "Ontario", 0 };
The simplest command which can give you what you need but some other good info too is:
hostnamectl
You can use echo and prefix "\033", simple:
Artisan::command('mycommand', function () {
echo "\033======== Start ========\n";
});
And change color text:
if (App::environment() === 'production') {
echo "\033[0;33m======== WARNING ========\033[0m\n";
}
If you do not want to use numpy,
sorted(range(len(seq)), key=seq.__getitem__)
is fastest, as demonstrated here.
Apple recommends for stylistic purposes.If you write this code:
@property (nonatomic,assign) BOOL working;
Then you can not use [object isWorking].
It will show an error. But if you use below code means
@property (assign,getter=isWorking) BOOL working;
So you can use [object isWorking] .
The only safe way to protect your code is not giving it away. With client deployment, there is no avoiding the client having access to the code.
So the short answer is: You can't do it
The longer answer is considering flash or Silverlight. Although I believe silverlight will gladly give away it's secrets with reflector running on the client.
I'm not sure if something simular exists with the flash platform.
A combobox is unfortunately something that was left out of the HTML specifications.
The only way to manage it, rather unfortunately, is to roll your own or use a pre-built one. This one looks quite simple. I use this one for an open-source app although unfortunately you have to pay for commercial usage.
As others answer 0

If you using bat file (window) System.exit(x)
will effect.
Code java (myapp):

code sample - https://codepen.io/nagasai/pen/GGzZVB
For security code, please don't generate your tokens this way: $token = md5(uniqid(rand(), TRUE));
rand()
is predictableuniqid()
only adds up to 29 bits of entropymd5()
doesn't add entropy, it just mixes it deterministicallyTry this out:
session_start();
if (empty($_SESSION['token'])) {
$_SESSION['token'] = bin2hex(random_bytes(32));
}
$token = $_SESSION['token'];
Sidenote: One of my employer's open source projects is an initiative to backport random_bytes()
and random_int()
into PHP 5 projects. It's MIT licensed and available on Github and Composer as paragonie/random_compat.
session_start();
if (empty($_SESSION['token'])) {
if (function_exists('mcrypt_create_iv')) {
$_SESSION['token'] = bin2hex(mcrypt_create_iv(32, MCRYPT_DEV_URANDOM));
} else {
$_SESSION['token'] = bin2hex(openssl_random_pseudo_bytes(32));
}
}
$token = $_SESSION['token'];
Don't just use ==
or even ===
, use hash_equals()
(PHP 5.6+ only, but available to earlier versions with the hash-compat library).
if (!empty($_POST['token'])) {
if (hash_equals($_SESSION['token'], $_POST['token'])) {
// Proceed to process the form data
} else {
// Log this as a warning and keep an eye on these attempts
}
}
You can further restrict tokens to only be available for a particular form by using hash_hmac()
. HMAC is a particular keyed hash function that is safe to use, even with weaker hash functions (e.g. MD5). However, I recommend using the SHA-2 family of hash functions instead.
First, generate a second token for use as an HMAC key, then use logic like this to render it:
<input type="hidden" name="token" value="<?php
echo hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
?>" />
And then using a congruent operation when verifying the token:
$calc = hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
if (hash_equals($calc, $_POST['token'])) {
// Continue...
}
The tokens generated for one form cannot be reused in another context without knowing $_SESSION['second_token']
. It is important that you use a separate token as an HMAC key than the one you just drop on the page.
Anyone who uses the Twig templating engine can benefit from a simplified dual strategy by adding this filter to their Twig environment:
$twigEnv->addFunction(
new \Twig_SimpleFunction(
'form_token',
function($lock_to = null) {
if (empty($_SESSION['token'])) {
$_SESSION['token'] = bin2hex(random_bytes(32));
}
if (empty($_SESSION['token2'])) {
$_SESSION['token2'] = random_bytes(32);
}
if (empty($lock_to)) {
return $_SESSION['token'];
}
return hash_hmac('sha256', $lock_to, $_SESSION['token2']);
}
)
);
With this Twig function, you can use both the general purpose tokens like so:
<input type="hidden" name="token" value="{{ form_token() }}" />
Or the locked down variant:
<input type="hidden" name="token" value="{{ form_token('/my_form.php') }}" />
Twig is only concerned with template rendering; you still must validate the tokens properly. In my opinion, the Twig strategy offers greater flexibility and simplicity, while maintaining the possibility for maximum security.
If you have a security requirement that each CSRF token is allowed to be usable exactly once, the simplest strategy regenerate it after each successful validation. However, doing so will invalidate every previous token which doesn't mix well with people who browse multiple tabs at once.
Paragon Initiative Enterprises maintains an Anti-CSRF library for these corner cases. It works with one-use per-form tokens, exclusively. When enough tokens are stored in the session data (default configuration: 65535), it will cycle out the oldest unredeemed tokens first.
Operators Overloadability
+, -, *, /, %, &, |, <<, >> All C# binary operators can be overloaded.
+, -, !, ~, ++, --, true, false All C# unary operators can be overloaded.
==, !=, <, >, <= , >= All relational operators can be overloaded,
but only as pairs.
&&, || They can't be overloaded
() (Conversion operator) They can't be overloaded
+=, -=, *=, /=, %= These compound assignment operators can be
overloaded. But in C#, these operators are
automatically overloaded when the respective
binary operator is overloaded.
=, . , ?:, ->, new, is, as, sizeof These operators can't be overloaded
[ ] Can be overloaded but not always!
For bracket:
public Object this[int index]
{
}
The array indexing operator cannot be overloaded; however, types can define indexers, properties that take one or more parameters. Indexer parameters are enclosed in square brackets, just like array indices, but indexer parameters can be declared to be of any type (unlike array indices, which must be integral).
From MSDN
From the man page, npm start:
runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.
Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.
Anyhow, what really happens is that npm looks in your package.json file, and if you have something like
"scripts": { "start": "coffee server.coffee" }
then it will do that. If npm can't find your start script, it defaults to:
node server.js
R.id.button
is not part of R.layout.activity_main
. How should the activity find it in the content view?
The layout that contains the button is displayed by the Fragment, so you have to get the Button there, in the Fragment.
To simplify this actions from accepted answer, you can also create Category for UIView
(since this works for all subclasses of UIView, not only for textfields:
UIView+Additions.h:
#import <Foundation/Foundation.h>
@interface UIView (Additions)
- (void)setBorderForColor:(UIColor *)color
width:(float)width
radius:(float)radius;
@end
UIView+Additions.m:
#import "UIView+Additions.h"
@implementation UIView (Additions)
- (void)setBorderForColor:(UIColor *)color
width:(float)width
radius:(float)radius
{
self.layer.cornerRadius = radius;
self.layer.masksToBounds = YES;
self.layer.borderColor = [color CGColor];
self.layer.borderWidth = width;
}
@end
Usage:
#import "UIView+Additions.h"
//...
[textField setBorderForColor:[UIColor redColor]
width:1.0f
radius:8.0f];
For Spring 4, using Spring Boot we can have the following example without using the anti-pattern of getting the Bean from the ApplicationContext directly:
package com.yourproject;
@SpringBootApplication
public class TestBed implements CommandLineRunner {
private MyService myService;
@Autowired
public TestBed(MyService myService){
this.myService = myService;
}
public static void main(String... args) {
SpringApplication.run(TestBed.class, args);
}
@Override
public void run(String... strings) throws Exception {
System.out.println("myService: " + MyService );
}
}
@Service
public class MyService{
public String getSomething() {
return "something";
}
}
Make sure that all your injected services are under com.yourproject
or its subpackages.
Just use memcpy.
If the destination isn't big enough, strncpy won't null terminate. if the destination is huge compared to the source, strncpy just fills the destination with nulls after the string. strncpy is pointless, and unsuitable for copying strings.
strncpy is like memcpy except it fills the destination with nulls once it sees one in the source. It's absolutely useless for string operations. It's for fixed with 0 padded records.
Sounds like you want:
var movies = _db.Movies.Where(p => p.Genres.Intersect(listOfGenres).Any());
Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

Here are the steps to edit the commit message of a previous commit (which is not the most recent commit) using SourceTree for Windows version 1.5.2.0:
Select the commit immediately before the commit that you want to edit. For example, if I want to edit the commit with message "FOOBAR!" then I need to select the commit that comes right before it:
Right-click on the selected commit and click Rebase children...interactively
:
Select the commit that you want to edit, then click Edit Message
at the
bottom. In this case, I'm selecting the commit with the message "FOOBAR!":
Edit the commit message, and then click OK
. In my example, I've added
"SHAZBOT! SKADOOSH!"
When you return to interactive rebase window, click on OK
to finish the
rebase:
At this point, you'll need to force-push your new changes since you've rebased commits that you've already pushed. However, the current 1.5.2.0 version of SourceTree for Windows does not allow you to force-push through the GUI, so you'll need to use Git from the command line anyways in order to do that.
Click Terminal
from the GUI to open up a terminal.
From the terminal force-push with the following command,
git push origin <branch> -f
where <branch>
is the name of the branch that you want to push, and -f
means
to force the push. The force push will overwrite your commits on your
remote repo, but that's OK in your case since you said that you're not sharing
your repo with other people.
That's it! You're done!

I recently dealt with this problem, and the cause of the problem turned out to be that the root certificate on the SMTP server that I was connecting to was the Sectigo root certificate that recently expired.
If you're connecting to the SMTP server by SSL/TLS or STARTTLS, and you've not changed anything recently in the environment where your PHPMailer script is running, and this problem suddenly occurred - then you might want to check for an expired or invalid certificate somewhere in the certificate chain on the server.
You can view the server's certificate chain using openssl s_client
.
For SSL/TLS on port 465:
openssl s_client -connect server.domain.tld:465 | openssl x509 -text
For STARTTLS on port 587:
openssl s_client -starttls smtp -crlf -connect server.domain.tld:587 | openssl x509 -text
There are basically two most popular answers. The first one basically says
Optimistic needs a three-tier architectures where you do not necessarily maintain a connection to the database for your session whereas Pessimistic Locking is when you lock the record for your exclusive use until you have finished with it. It has much better integrity than optimistic locking you need either a direct connection to the database.
optimistic (versioning) is faster because of no locking but (pessimistic) locking performs better when contention is high and it is better to prevent the work rather than discard it and start over.
or
Optimistic locking works best when you have rare collisions
As it is put on this page.
I created my answer to explain how "keep connection" is related to "low collisions".
To understand which strategy is best for you, think not about the Transactions Per Second your DB has but the duration of a single transaction. Normally, you open trasnaction, performa operation and close the transaction. This is a short, classical transaction ANSI had in mind and fine to get away with locking. But, how do you implement a ticket reservation system where many clients reserve the same rooms/seats at the same time?
You browse the offers, fill in the form with lots of available options and current prices. It takes a lot of time and options can become obsolete, all the prices invalid between you started to fill the form and press "I agree" button because there was no lock on the data you have accessed and somebody else, more agile, has intefered changing all the prices and you need to restart with new prices.
You could lock all the options as you read them, instead. This is pessimistic scenario. You see why it sucks. Your system can be brought down by a single clown who simply starts a reservation and goes smoking. Nobody can reserve anything before he finishes. Your cash flow drops to zero. That is why, optimistic reservations are used in reality. Those who dawdle too long have to restart their reservation at higher prices.
In this optimistic approach you have to record all the data that you read (as in mine Repeated Read) and come to the commit point with your version of data (I want to buy shares at the price you displayed in this quote, not current price). At this point, ANSI transaction is created, which locks the DB, checks if nothing is changed and commits/aborts your operation. IMO, this is effective emulation of MVCC, which is also associated with Optimistic CC and also assumes that your transaction restarts in case of abort, that is you will make a new reservation. A transaction here involves a human user decisions.
I am far from understanding how to implement the MVCC manually but I think that long-running transactions with option of restart is the key to understanding the subject. Correct me if I am wrong anywhere. My answer was motivated by this Alex Kuznecov chapter.
void foo(vector<int> test)
vector would be passed by value in this.
You have more ways to pass vectors depending on the context:-
1) Pass by reference:- This will let function foo change your contents of the vector. More efficient than pass by value as copying of vector is avoided.
2) Pass by const-reference:- This is efficient as well as reliable when you don't want function to change the contents of the vector.

sudo /opt/lampp/lampp restart
Copy the diff file to the root of your repository, and then do:
git apply yourcoworkers.diff
More information about the apply
command is available on its man page.
By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch
on the sender and then git am
on the receiver, because it also transfers the authorship info and the commit message.
If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3
option of apply
that tries to merge in the changes.
It also works with Unix pipe as follows:
git diff d892531 815a3b5 | git apply
I just discovered Telerik has some great components, including Grid, and they are open source too. http://demos.telerik.com/aspnet-mvc/
If you're using C++ ranges - the full ranges-v3 library, not the limited functionality accepted into C++20 - you could do it this way:
auto results = str | ranges::views::tokenize(" ",1);
... and this is lazily-evaluated, i.e. O(1) time and space. You can alternatively set a vector to this range:
auto results = str | ranges::views::tokenize(" ",1) | to<std::vector>();
this will take O(m) space and O(n) time if str
has n characters making up m words.
See also the library's own tokenization example, here.
Simple Query:
SELECT DATEADD(m, DATEDIFF(m, 0, GETDATE()), 0)
-- Instead of GetDate you can put any date.
You can try this solution, since onkeypress will be attached directly to the DOM element and will prevent users from entering invalid data to begin with.
So no side-effects on react side.
<input type="text" onKeyPress={onNumberOnlyChange}/>
const onNumberOnlyChange = (event: any) => {
const keyCode = event.keyCode || event.which;
const keyValue = String.fromCharCode(keyCode);
const isValid = new RegExp("[0-9]").test(keyValue);
if (!isValid) {
event.preventDefault();
return;
}
};

Route::get('/', function()
{
return View::make('home.index');
});
Route::get('user', function()
{
return View::make('user.index');
});
change above to
Route::get('user', function()
{
return View::make('user.index');
});
Route::get('/', function()
{
return View::make('home.index');
});
You have to use '/'(home/default) at the end in your routes

I prefer Serializable
= no boilerplate code. For passing data to other Fragments or Activities the speed difference to a Parcelable
does not matter.
I would also always provide a helper method for a Fragment
or Activity
, this way you always know, what data has to be passed. Here an example for your ListMusicFragment
:
private static final String EXTRA_MUSIC_LIST = "music_list";
public static ListMusicFragment createInstance(List<Music> music) {
ListMusicFragment fragment = new ListMusicFragment();
Bundle bundle = new Bundle();
bundle.putSerializable(EXTRA_MUSIC_LIST, music);
fragment.setArguments(bundle);
return fragment;
}
@Override
public View onCreateView(...) {
...
Bundle bundle = intent.getArguments();
List<Music> musicList = (List<Music>)bundle.getSerializable(EXTRA_MUSIC_LIST);
...
}
I'll start off with this: consistency is king, the decision is less important than the consistency in your code base.
NULL is defined as 0
or 0L
in C++.
If you've read The C++ Programming Language Bjarne Stroustrup suggests using 0
explicitly to avoid the NULL
macro when doing assignment, I'm not sure if he did the same with comparisons, it's been a while since I read the book, I think he just did if(some_ptr)
without an explicit comparison but I am fuzzy on that.
The reason for this is that the NULL
macro is deceptive (as nearly all macros are) it is actually 0
literal, not a unique type as the name suggests it might be. Avoiding macros is one of the general guidelines in C++. On the other hand, 0
looks like an integer and it is not when compared to or assigned to pointers. Personally I could go either way, but typically I skip the explicit comparison (though some people dislike this which is probably why you have a contributor suggesting a change anyway).
Regardless of personal feelings this is largely a choice of least evil as there isn't one right method.
This is clear and a common idiom and I prefer it, there is no chance of accidentally assigning a value during the comparison and it reads clearly:
if (some_ptr) {}
This is clear if you know that some_ptr
is a pointer type, but it may also look like an integer comparison:
if (some_ptr != 0) {}
This is clear-ish, in common cases it makes sense... But it's a leaky abstraction, NULL
is actually 0
literal and could end up being misused easily:
if (some_ptr != NULL) {}
C++11 has nullptr
which is now the preferred method as it is explicit and accurate, just be careful about accidental assignment:
if (some_ptr != nullptr) {}
Until you are able to migrate to C++0x I would argue it's a waste of time worrying about which of these methods you use, they are all insufficient which is why nullptr was invented (along with generic programming issues which came up with perfect forwarding.) The most important thing is to maintain consistency.
C is a different beast.
In C NULL
can be defined as 0
or as ((void *)0)
, C99 allows for implementation defined null pointer constants. So it actually comes down to the implementation's definition of NULL
and you will have to inspect it in your standard library.
Macros are very common and in general they are used a lot to make up for deficiencies in generic programming support in the language and other things as well. The language is much simpler and reliance on the preprocessor more common.
From this perspective I'd probably recommend using the NULL
macro definition in C.
Seems that there's enough variation that people go out of their way to allow conversion from all conventions to others: http://www.cowtowncoder.com/blog/archives/cat_json.html
Notably, the mentioned Jackson JSON parser prefers bean_naming
.
One thing json
cannot do is dict
indexed with numerals. The following snippet
import json
dictionary = dict({0:0, 1:5, 2:10})
serialized = json.dumps(dictionary)
unpacked = json.loads(serialized)
print(unpacked[0])
will throw
KeyError: 0
Because keys are converted to strings. cPickle
preserves the numeric type and the unpacked dict
can be used right away.
The best way to do it is by using linq.
Example class:
public class Product
{
public string Name { get; set; }
public string Price { get; set; }
}
Linq query:
var subCollection = collection1.RemoveAll(w => collection2.Any(q => q.Name == w.Name));
This query will remove all elements from collection1
if Name
match any element Name
from collection2
Remember to use: using System.Linq;
If the memory of the Mat mat
is continuous (all its data is continuous), you can directly get its data to a 1D array:
std::vector<uchar> array(mat.rows*mat.cols*mat.channels());
if (mat.isContinuous())
array = mat.data;
Otherwise, you have to get its data row by row, e.g. to a 2D array:
uchar **array = new uchar*[mat.rows];
for (int i=0; i<mat.rows; ++i)
array[i] = new uchar[mat.cols*mat.channels()];
for (int i=0; i<mat.rows; ++i)
array[i] = mat.ptr<uchar>(i);
UPDATE: It will be easier if you're using std::vector
, where you can do like this:
std::vector<uchar> array;
if (mat.isContinuous()) {
// array.assign(mat.datastart, mat.dataend); // <- has problems for sub-matrix like mat = big_mat.row(i)
array.assign(mat.data, mat.data + mat.total()*mat.channels());
} else {
for (int i = 0; i < mat.rows; ++i) {
array.insert(array.end(), mat.ptr<uchar>(i), mat.ptr<uchar>(i)+mat.cols*mat.channels());
}
}
p.s.: For cv::Mat
s of other types, like CV_32F
, you should do like this:
std::vector<float> array;
if (mat.isContinuous()) {
// array.assign((float*)mat.datastart, (float*)mat.dataend); // <- has problems for sub-matrix like mat = big_mat.row(i)
array.assign((float*)mat.data, (float*)mat.data + mat.total()*mat.channels());
} else {
for (int i = 0; i < mat.rows; ++i) {
array.insert(array.end(), mat.ptr<float>(i), mat.ptr<float>(i)+mat.cols*mat.channels());
}
}
UPDATE2: For OpenCV Mat data continuity, it can be summarized as follows:
imread()
, clone()
, or a constructor will always be continuous.Please check out this code snippet for demonstration.
It was suggested to post this as an answer, because some other answers are giving errors like 'The name Context does not exist in the current context'.
Just using the following works:
Request.Query["queryparm1"]
Sample usage:
<a href="@Url.Action("Query",new {parm1=Request.Query["queryparm1"]})">GO</a>
git reset 'HEAD@{1}'
Git keeps a log of all ref updates (e.g., checkout, reset, commit, merge). You can view it by typing:
git reflog
Somewhere in this list is the commit that you lost. Let's say you just typed git reset HEAD~
and want to undo it. My reflog looks like this:
$ git reflog
3f6db14 HEAD@{0}: HEAD~: updating HEAD
d27924e HEAD@{1}: checkout: moving from d27924e0fe16776f0d0f1ee2933a0334a4787b4c
[...]
The first line says that HEAD
0 positions ago (in other words, the current position) is 3f6db14; it was obtained by resetting to HEAD~
. The second line says that HEAD
1 position ago (in other words, the state before the reset) is d27924e. It was obtained by checking out a particular commit (though that's not important right now). So, to undo the reset, run git reset HEAD@{1}
(or git reset d27924e
).
If, on the other hand, you've run some other commands since then that update HEAD, the commit you want won't be at the top of the list, and you'll need to search through the reflog
.
One final note: It may be easier to look at the reflog
for the specific branch you want to un-reset, say master, rather than HEAD
:
$ git reflog show master
c24138b master@{0}: merge origin/master: Fast-forward
90a2bf9 master@{1}: merge origin/master: Fast-forward
[...]
This should have less noise it in than the general HEAD reflog
.
As the other answers have said, Spring just takes care of it, creating the beans and injecting them as required.
One of the consequences is that bean injection / property setting might occur in a different order to what your XML wiring files would seem to imply. So you need to be careful that your property setters don't do initialization that relies on other setters already having been called. The way to deal with this is to declare beans as implementing the InitializingBean
interface. This requires you to implement the afterPropertiesSet()
method, and this is where you do the critical initialization. (I also include code to check that important properties have actually been set.)

jFeed is easy and has an example for you to test. But if you're parsing a feed from another server, you'll need to allow Cross Origin Resource Sharing (CORS) on the feed's server. You'll also need to check browser support.
I uploaded the sample but still did not get support from IE in any version when I changed the url in the example to something like example.com/feed.rss via the http protocol. CORS should be supported for IE 8 and above but the jFeed example did not render the feed.
Your best bet is to use Google's API:

I have been battling this for a about a week. I'm trying to learn Java on Netbeans IDE and so naturally I get the combo file straight from Oracle. Which is a package of the JDK and the Netbeans IDE together in a tar file located here.
located http://www.oracle.com/technetwork/java/javase/downloads/index.html file name JDK 8u25 with NetBeans 8.0.1
after installing them (or so I thought) I would make/compile a simple program like "hello world" and that would spit out a jar file that you would be able to run in a terminal. Keep in mind that the program ran in the Netbeans IDE.
I would end up with this error: java.lang.UnsupportedClassVersionError:
Even though I ran the file from oracle website I still had the old version of the Java runtime which was not compatible to run my jar file which was compiled with the new java runtime.
After messing with stuff that was mostly over my head from setting Paths to editing .bashrc with no remedy.
I came across a solution that was easy enough for even me. I have come across something that auto installs java and configures it on your system and it works with the latest 1.8.*
One of the steps is adding a PPA wasn't sure about this at first but seems ok as it has worked for me
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
domenic@domenic-AO532h ~ $ java -version java version "1.8.0_25" Java(TM) SE Runtime Environment (build 1.8.0_25-b17) Java HotSpot(TM) Server VM (build 25.25-b02, mixed mode)
I think it also configures the browser java as well.
I hope this helps others.

contentType
option to false
is used for multipart/form-data
forms that pass files.
When one sets the contentType
option to false
, it forces jQuery not to add a Content-Type header, otherwise, the boundary string will be missing from it. Also, when submitting files via multipart/form-data, one must leave the processData
flag set to false, otherwise, jQuery will try to convert your FormData into a string, which will fail.
Use jQuery's .serialize()
method which creates a text string in standard URL-encoded notation.
You need to pass un-encoded data when using contentType: false
.
Try using new FormData
instead of .serialize():
var formData = new FormData($(this)[0]);
See for yourself the difference of how your formData is passed to your php page by using console.log()
.
var formData = new FormData($(this)[0]);
console.log(formData);
var formDataSerialized = $(this).serialize();
console.log(formDataSerialized);
Try This,
public View getView(final int position, View convertView,ViewGroup parent)
{
if(convertView == null)
{
LayoutInflater inflater = getLayoutInflater();
convertView = (LinearLayout)inflater.inflate(R.layout.YOUR_LAYOUT, null);
}
Button Button1= (Button) convertView .findViewById(R.id.BUTTON1_ID);
Button1.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// Your code that you want to execute on this button click
}
});
return convertView ;
}

The documentation for css() says that setting the style property to the empty string will remove that property if it does not reside in a stylesheet:
Setting the value of a style property to an empty string — e.g.
$('#mydiv').css('color', '')
— removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's.css()
method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or<style>
element.
Since your styles are inline, you can write:
$(selector).css("-moz-user-select", "");
Yes. The answer is yes.

var A = ['Sunday','Monday','Tuesday','Wednesday','Thursday']

That's it Now A is a string. :)
Python 3 has the facility of Launching parallel tasks. This makes our work easier.
It has for thread pooling and Process pooling.
The following gives an insight:

# We can use a with statement to ensure threads are cleaned up promptly
with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
# Start the load operations and mark each future with its URL
future_to_url = {executor.submit(load_url, url, 60): url for url in URLS}

Add attributed text color in swift code.
Swift 4:
let greenColor = UIColor(red: 10/255, green: 190/255, blue: 50/255, alpha: 1)
let attributedStringColor = [NSAttributedStringKey.foregroundColor : greenColor];
let attributedString = NSAttributedString(string: "Hello World!", attributes: attributedStringColor)
label.attributedText = attributedString
for Swift 3:
let greenColor = UIColor(red: 10/255, green: 190/255, blue: 50/255, alpha: 1)
let attributedStringColor : NSDictionary = [NSForegroundColorAttributeName : greenColor];
let attributedString = NSAttributedString(string: "Hello World!", attributes: attributedStringColor as? [String : AnyObject])
label.attributedText = attributedString

The A div can actually be made without :before
or :after
selector but using linear gradient as your first try. The only difference is that you must specify 4 positions. Dark grey from 0 to 50% and ligth grey from 50% to 100% like this:
background: linear-gradient(to right, #9c9e9f 0%,#9c9e9f 50%,#f6f6f6 50%,#f6f6f6 100%);
As you know, B div is made from a linear gradient having 2 positions like this:
background: linear-gradient(to right, #9c9e9f 0%,#f6f6f6 100%);
For the C div, i use the same kind of gradient as div A ike this:
background: linear-gradient(to right, #9c9e9f 0%,#9c9e9f 50%,#33ccff 50%,#33ccff 100%);
But this time i used the :after
selector with a white background like if the second part of your div was smaller. * Please note that I added a better alternative below.

There is also an alternative for the C div without using a white background to hide the a part of the second section.
Instead, we make the second part transparent and we use the :after
selector to act as a colored background with the desired position and size.

Well, my solution is sort of hack, but it works and I am using it.
1vw = 1% of viewport width
1vh = 1% of viewport height
1vmin = 1vw or 1vh, whichever is smaller
1vmax = 1vw or 1vh, whichever is larger
h1 {
font-size: 5.9vw;
}
h2 {
font-size: 3.0vh;
}
p {
font-size: 2vmin;
}
in these cases you can try ssh if https is stuck.
Also you can try increasing the buffer size to an astronomical figure so that you dont have to worry about the buffer size any more git config http.postBuffer 100000000
The primary consumers of these properties are user agents such as screen readers for blind people. So in the case with a Bootstrap modal, the modal's div

becomes visible which has this role, it'll speak the label for that div
.
There are lots of ways to label things (and a few new ones with ARIA), but in some cases it is appropriate to use an existing element as a label (semantic) without using the <label>
HTML tag. With HTML modals the label is usually a <h>
header. So in the Bootstrap modal case, you add aria-labelledby=[IDofModalHeader]
, and the screen reader will speak that header when the modal appears.
Generally speaking a screen reader is going to notice whenever DOM elements become visible or invisible, so the aria-hidden
property is frequently redundant and can probably be skipped in most cases.
The answer is:
<a href="page.html" onclick="return false">page link</a>
You should use the OpenFileDialog class like this
Dim fd As OpenFileDialog = New OpenFileDialog()
Dim strFileName As String
fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True
If fd.ShowDialog() = DialogResult.OK Then
strFileName = fd.FileName
End If
Then you can use the File class.

For an option that looks more like what you get when you print from a browser, wkhtmltopdf
provides one option.
On Ubuntu
sudo apt-get install wkhtmltopdf
And then the same command as for the pandoc example to get to the HTML:
RMDFILE=example-r-markdown
Rscript -e "require(knitr); require(markdown); knit('$RMDFILE.rmd', '$RMDFILE.md'); markdownToHTML('$RMDFILE.md', '$RMDFILE.html', options=c('use_xhml'))"
and then
wkhtmltopdf example-r-markdown.html example-r-markdown.pdf
The resulting file looked like this. It did not seem to handle the MathJax (this issue is discussed here), and the page breaks are ugly. However, in some cases, such a style might be preferred over a more LaTeX style presentation.
I think the problem is the realpath of the file. For example your script is working on './', your file is inside the directory './xml'. So better check if the file exists or not, before you get filemtime or unlink it:
function deleteOldFiles(){
if ($handle = opendir('./xml')) {
while (false !== ($file = readdir($handle))) {
if(preg_match("/^.*\.(xml|xsl)$/i", $file)){
$fpath = 'xml/'.$file;
if (file_exists($fpath)) {
$filelastmodified = filemtime($fpath);
if ( (time() - $filelastmodified ) > 24*3600){
unlink($fpath);
}
}
}
}
closedir($handle);
}
}
A trick to make a PDF with complex features is to make a dummy activity with the desired xml layout. You can then open this dummy activity, take a screenshot programmatically and convert that image to pdf using this library. Of course there are limitations such as not being able to scroll, not more than one page,but for a limited application this is quick and easy. Hope this helps someone!
Step 1: Implement an interface with your activity class
public class AuthenticatedMainActivity extends Activity implements FragmentManager.OnBackStackChangedListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
.............
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().add(R.id.frame_container,fragment, "First").addToBackStack(null).commit();
}
private void switchFragment(Fragment fragment){
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).addToBackStack("Tag").commit();
}
@Override
public void onBackStackChanged() {
FragmentManager fragmentManager = getFragmentManager();
System.out.println("@Class: SummaryUser : onBackStackChanged "
+ fragmentManager.getBackStackEntryCount());
int count = fragmentManager.getBackStackEntryCount();
// when a fragment come from another the status will be zero
if(count == 0){
System.out.println("again loading user data");
// reload the page if user saved the profile data
if(!objPublicDelegate.checkNetworkStatus()){
objPublicDelegate.showAlertDialog("Warning"
, "Please check your internet connection");
}else {
objLoadingDialog.show("Refreshing data...");
mNetworkMaster.runUserSummaryAsync();
}
// IMPORTANT: remove the current fragment from stack to avoid new instance
fragmentManager.removeOnBackStackChangedListener(this);
}// end if
}
}
Step 2: When you call the another fragment add this method:
String backStateName = this.getClass().getName();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.addOnBackStackChangedListener(this);
Fragment fragmentGraph = new GraphFragment();
Bundle bundle = new Bundle();
bundle.putString("graphTag", view.getTag().toString());
fragmentGraph.setArguments(bundle);
fragmentManager.beginTransaction()
.replace(R.id.content_frame, fragmentGraph)
.addToBackStack(backStateName)
.commit();
Ben has told you how to revert a merge commit, but it's very important you realize that in doing so
"...declares that you will never want the tree changes brought in by the merge. As a result, later merges will only bring in tree changes introduced by commits that are not ancestors of the previously reverted merge. This may or may not be what you want." (git-merge man page).
An article/mailing list message linked from the man page details the mechanisms and considerations that are involved. Just make sure you understand that if you revert the merge commit, you can't just merge the branch again later and expect the same changes to come back.
Similar to Kaspar's answer but with the g flag to replace all the occurrences on a line.
find ./ -type f -exec sed -i 's/string1/string2/g' {} \;
For global case insensitive:
find ./ -type f -exec sed -i 's/string1/string2/gI' {} \;
This may be old, but... if you change the link in google stock list as below:
It means, starting for row 1 to 30000. It shows all results in one page.
You may automate it using any language or just export the table to excel.
Hope it helps.
In Python 3 the following should work:
max(set(a), key=lambda x: a.count(x))
This works for me with validation of bootstrap
$(document).ready(function() {
$("#fname").keypress(function(e) {
var regex = new RegExp("^[a-zA-Z ]+$");
var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
if (regex.test(str)) {
return true;
}
You can use fetch optionally with await-try-catch
let photo = document.getElementById("image-file").files[0];
let formData = new FormData();
formData.append("photo", photo);
fetch('/upload/image', {method: "POST", body: formData});
async function SavePhoto(inp)
{
let user = { name:'john', age:34 };
let formData = new FormData();
let photo = inp.files[0];
formData.append("photo", photo);
formData.append("user", JSON.stringify(user));
const ctrl = new AbortController() // timeout
setTimeout(() => ctrl.abort(), 5000);
try {
let r = await fetch('/upload/image',
{method: "POST", body: formData, signal: ctrl.signal});
console.log('HTTP response code:',r.status);
} catch(e) {
console.log('Huston we have problem...:', e);
}
}

Old school approach - xhr
let photo = document.getElementById("image-file").files[0]; // file from input
let req = new XMLHttpRequest();
let formData = new FormData();
formData.append("photo", photo);
req.open("POST", '/upload/image');
req.send(formData);
function SavePhoto(e)
{
let user = { name:'john', age:34 };
let xhr = new XMLHttpRequest();
let formData = new FormData();
let photo = e.files[0];
formData.append("user", JSON.stringify(user));
formData.append("photo", photo);
xhr.onreadystatechange = state => { console.log(xhr.status); } // err handling
xhr.timeout = 5000;
xhr.open("POST", '/upload/image');
xhr.send(formData);
}

(the stack overflow snippets, has some problem with error handling - the xhr.status is zero (instead of 404) which is similar to situation when we run script from file on <a href="https://stackoverflow.com/a/10173639/860099">local disc</a> - so I provide also js fiddle version which shows proper http error code <a href="https://jsfiddle.net/Lamik/k6jtq3uh/2/">here</a>)

SUMMARY
filename
formData parameter.Content-Type
to multipart/form-data
- this will be set automatically by browser./upload/image
you can use full address like http://.../upload/image
.multiple
attribute: <input multiple type=... />
, and attach all chosen files to formData in similar way (e.g. photo2=...files[2];
... formData.append("photo2", photo2);
)let user = {name:'john', age:34}
in this way: formData.append("user", JSON.stringify(user));
fetch
using AbortController
, for old approach by xhr.timeout= milisec
In native Hibernate XML mappings, you can accomplish this by declaring a one-to-one mapping with the constrained attribute set to true. I am not sure what the Hibernate/JPA annotation equivalent of that is, and a quick search of the doc provided no answer, but hopefully that gives you a lead to go on.
When you call a function, a new "namespace" is allocated on the stack. That's how functions can have local variables. As functions call functions, which in turn call functions, we keep allocating more and more space on the stack to maintain this deep hierarchy of namespaces.
To curb programs using massive amounts of stack space, a limit is usually put in place via ulimit -s
. If we remove that limit via ulimit -s unlimited
, our programs will be able to keep gobbling up RAM for their evergrowing stack until eventually the system runs out of memory entirely.
int eat_stack_space(void) { return eat_stack_space(); }
// If we compile this with no optimization and run it, our computer could crash.
Usually, using a ton of stack space is accidental or a symptom of very deep recursion that probably should not be relying so much on the stack. Thus the stack limit.
Impact on performace is minor but does exist. Using the time
command, I found that eliminating the stack limit increased performance by a few fractions of a second (at least on 64bit Ubuntu).
You can set the line height on the text, for example within the active class:
.active {
...
line-height: 2em;

}
Your definition of myFunction is wrong. It should be:
myFunction()
{
# same as before
}
or:
function myFunction
{
# same as before
}
Anyway, it looks fine and works fine for me on Bash 3.2.48.
Also for openCV in python you can do:
img = cv2.imread('myImage.jpg')
height, width, channels = img.shape
I dont know if you want to achieve that in js or java, in js the simplest way to get the unix timestampt (this is time in seconds from 1/1/1970) it's as follows:
var myDate = new Date();
console.log(+myDate); // +myDateObject give you the unix from that date
You can try this
$('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});
The $('div.easy_editor')
refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.
Not tried it with combo boxes but this has worked for me with other controls...

If someone is facing issue using texttocolumns function in UFT. Please try using below function.

Set objRange = myxl.Range("A1").EntireColumn
Set objRange2 = mysheet.Range("A1")
objRange.TextToColumns objRange2,1,1, , , , true
Here we are using coma(,) as delimiter.
I had the same issue.
Solution was to change the platform of my current solution to x64.
To do that in Visual Studio, right click solution > Configuration Manager > Active Solution Platform.

echo 'export HISTTIMEFORMAT="%d/%m/%y %T "' >> ~/.bash_profile
source ~/.bash_profile
If you wish to use 2 subdomains to other ports, you can use Minecraft's proxy server (it means BungeeCord, Waterfall, Travertine...), and bind subdomain to specifiend in config.yml server. To do that you have to setup your servers in BungeeCord's config:
servers:
pvp:
motd: 'A Minecraft Server PVP'
address: localhost:25566
restricted: false
skyblock:
motd: 'A Minecraft Server SkyBlock'
address: localhost:25567
restricted: false
Remember! Ports must be diffrent than default Minecraft's port (it means 25565), because we will use this port to our proxy. sub1.domain.com and sub2.domain.com we have to bind to server where you have these servers. Now, we have to bind subdomains in your Bungee server:
listeners:
forced_hosts:
sub1.domain.com: pvp
sub2.domain.com: skyblock
domain.com: pvp // You can bind other domains to same servers.
Remember to change force_default_server to true, and change host to 0.0.0.0:25565 Example of BungeeCord's config.yml with some servers: https://pastebin.com/tA9ktZ6f Now you can connect to your pvp server on sub1.domain.com and connect to skyblock on sub2.domain.com. Don't worry, BungeeCord takes only 0,5GB of RAM for 500 players.
Use Process Explorer from the Sysinternals Suite, the Find Handle or DLL function will let you search for the process with that file open.
If you wish to change the font color inside string.xml
file, you may try the following code.

For solution just uncomment line 29:
**protected $namespace = 'App\\Http\\Controllers';**
in 'app\Providers\RouteServiceProvider.php' file.
Use MySQL's FIELD()
function:
SELECT name, description, ...
FROM ...
WHERE id IN([ids, any order])
ORDER BY FIELD(id, [ids in order])
FIELD()
will return the index of the first parameter that is equal to the first parameter (other than the first parameter itself).
FIELD('a', 'a', 'b', 'c')
will return 1
FIELD('a', 'c', 'b', 'a')
will return 3
This will do exactly what you want if you paste the ids into the IN()
clause and the FIELD()
function in the same order.

I usually add to index changes I don't want to stash and then stash with --keep-index
option.
git add app/controllers/cart_controller.php
git stash --keep-index
git reset
Last step is optional, but usually you want it. It removes changes from index.
Warning
As noted in the comments, this puts everything into the stash, both staged and unstaged. The --keep-index
just leaves the index alone after the stash is done. This can cause merge conflicts when you later pop the stash.
You can set your content-type header so clients know to expect json
w.Header().Set("Content-Type", "application/json")
Another way to marshal a struct to json is to build an encoder using the http.ResponseWriter
// get a payload p := Payload{d}
json.NewEncoder(w).Encode(p)
As addition of good answers, You don't have to use [FromForm]
to get form data in controller. Framework automatically convert form data to model as you wish. You can implement like following.
[HttpPost]
public async Task<IActionResult> Submit(MyModel model)
{
//...
}
This is working for IE/Netscape/Chrome :
function ClearAuthentication(LogOffPage)
{
var IsInternetExplorer = false;
try
{
var agt=navigator.userAgent.toLowerCase();
if (agt.indexOf("msie") != -1) { IsInternetExplorer = true; }
}
catch(e)
{
IsInternetExplorer = false;
};
if (IsInternetExplorer)
{
// Logoff Internet Explorer
document.execCommand("ClearAuthenticationCache");
window.location = LogOffPage;
}
else
{
// Logoff every other browsers
$.ajax({
username: 'unknown',
password: 'WrongPassword',
url: './cgi-bin/PrimoCgi',
type: 'GET',
beforeSend: function(xhr)
{
xhr.setRequestHeader("Authorization", "Basic AAAAAAAAAAAAAAAAAAA=");
},
error: function(err)
{
window.location = LogOffPage;
}
});
}
}
$(document).ready(function ()
{
$('#Btn1').click(function ()
{
// Call Clear Authentication
ClearAuthentication("force_logout.html");
});
});
If you need two or more dealings with the filter, is possible to chain them:
{{ value | decimalRound: 2 | currencySimbol: 'U$' }}
// 11.1111 becomes U$ 11.11
Trying to handle the URI with content:// scheme by calling ContentResolver.query()
is not a good solution. On HTC Desire running 4.2.2 you could get NULL as a query result.
Why not to use ContentResolver instead? https://stackoverflow.com/a/29141800/3205334
