If you only call print
without any arguments, it will output a blank line.
print
You can pipe the output to a file like this (considering your example):
f = open('out.txt', 'w')
print 'First line' >> f
print >> f
print 'Second line' >> f
f.close()
Not only is it OS-agnostic (without even having to use the os
package), it's also more readable than putting \n
within strings.
The print()
function has an optional keyword argument for the end of the string, called end
, which defaults to the OS's newline character, for eg. \n
. So, when you're calling print('hello')
, Python is actually printing 'hello' + '\n'
. Which means that when you're calling just print
without any arguments, it's actually printing '' + '\n'
, which results in a newline.
Use multi-line strings.
s = """First line
Second line
Third line"""
f = open('out.txt', 'w')
print s >> f
f.close()
You can do as follow :
import json
exDict = {1:1, 2:2, 3:3}
file.write(json.dumps(exDict))
https://developer.rhino3d.com/guides/rhinopython/python-xml-json/
You can redirect print with the >>
operator.
f = open(filename,'w')
print >>f, 'whatever' # Python 2.x
print('whatever', file=f) # Python 3.x
In most cases, you're better off just writing to the file normally.
f.write('whatever')
or, if you have several items you want to write with spaces between, like print
:
f.write(' '.join(('whatever', str(var2), 'etc')))
This method is even easier if you're ok with fewer options:
FileCopy source, destination
Explanation of stereotypes :
@Service
- Annotate all your service classes with @Service. This layer knows the unit of work. All your business logic will be in Service classes. Generally methods of service layer are covered under transaction. You can make multiple DAO calls from service method, if one transaction fails all transactions should rollback.@Repository
- Annotate all your DAO classes with @Repository. All your database access logic should be in DAO classes.@Component
- Annotate your other components (for example REST resource classes) with component stereotype.@Autowired
- Let Spring auto-wire other beans into your classes using @Autowired annotation. @Component
is a generic stereotype for any Spring-managed component. @Repository
, @Service
, and @Controller
are specializations of @Component
for more specific use cases, for example, in the persistence, service, and presentation layers, respectively.

Another easy solution to disable swiping at specific page (in this example, page 2):
int PAGE = 2;
viewPager.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (viewPager.getCurrentItem() == PAGE) {
viewPager.setCurrentItem(PAGE-1, false);
viewPager.setCurrentItem(PAGE, false);
return true;
}
return false;
}
Without mod_expires it will be harder to set expiration headers on your files. For anything generated you can certainly set some default headers on the answer, doing the job of mod_expires like that:
<?php header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T', time() + 3600)); ?>
(taken from: Stack Overflow answer from @brianegge, where the mod_expires solution is also explained)
Now this won't work for static files, like your javascript files. As for static files there is only apache (without any expiration module) between the browser and the source file.
To prevent caching of javascript files, which is done on your browser, you can use a random token at the end of the js url, something like ?rd=45642111
, so the url looks like:
<script type="texte/javascript" src="my/url/myjs.js?rd=4221159546">
If this url on the page is generated by a PHP file you can simply add the random part with PHP. This way of randomizing url by simply appending random query string parameters is the base thing upôn no-cache setting of ajax jQuery request for example. The browser will never consider 2 url having different query strings to be the same, and will never use the cached version.
EDIT
Note that you should alos test mod_headers. If you have mod_headers you can maybe set the Expires headers directly with the Header keyword.
What you asked for is:
IF OBJECT_ID('tempdb..##CLIENTS_KEYWORD') IS NOT NULL
BEGIN
DROP TABLE ##CLIENTS_KEYWORD
CREATE TABLE ##CLIENTS_KEYWORD(client_id int)
END
ELSE
CREATE TABLE ##CLIENTS_KEYWORD(client_id int)
IF OBJECT_ID('tempdb..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
BEGIN
DROP TABLE ##TEMP_CLIENTS_KEYWORD
CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int)
END
ELSE
CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int)
Since you're always going to create the table, regardless of whether the table is deleted or not; a slightly optimised solution is:
IF OBJECT_ID('tempdb..##CLIENTS_KEYWORD') IS NOT NULL
DROP TABLE ##CLIENTS_KEYWORD
CREATE TABLE ##CLIENTS_KEYWORD(client_id int)
IF OBJECT_ID('tempdb..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
DROP TABLE ##TEMP_CLIENTS_KEYWORD
CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int)
When you type "java -version", you see three version numbers - the java version (on mine, that's "1.6.0_07
"), the Java SE Runtime Environment version ("build 1.6.0_07-b06
"), and the HotSpot version (on mine, that's "build 10.0-b23, mixed mode"
). I suspect the "11.0" you are seeing is the HotSpot version.
Update: HotSpot is (or used to be, now they seem to use it to mean the whole VM) the just-in-time compiler that is built in to the Java Virtual Machine. God only knows why Sun gives it a separate version number.
Before installation use the Control Panel Region and Language Preferences tool to change everything (Format, Keyboard default input, language for non Unicode programs) to English. Revert to the original selections after the installation.
For end of line use:
git diff --ignore-space-at-eol
Instead of what are you using currently:
git diff -w (--ignore-all-space)
For start of line... you are out of luck if you want a built in solution.
However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".
I currently use this function in my project after a series of googling to download excel file from sql statement
// $sql = sql query e.g "select * from mytablename"
// $filename = name of the file to download
function queryToExcel($sql, $fileName = 'name.xlsx') {
// initialise excel column name
// currently limited to queries with less than 27 columns
$columnArray = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z");
// Execute the database query
$result = mysql_query($sql) or die(mysql_error());
// Instantiate a new PHPExcel object
$objPHPExcel = new PHPExcel();
// Set the active Excel worksheet to sheet 0
$objPHPExcel->setActiveSheetIndex(0);
// Initialise the Excel row number
$rowCount = 1;
// fetch result set column information
$finfo = mysqli_fetch_fields($result);
// initialise columnlenght counter
$columnlenght = 0;
foreach ($finfo as $val) {
// set column header values
$objPHPExcel->getActiveSheet()->SetCellValue($columnArray[$columnlenght++] . $rowCount, $val->name);
}
// make the column headers bold
$objPHPExcel->getActiveSheet()->getStyle($columnArray[0]."1:".$columnArray[$columnlenght]."1")->getFont()->setBold(true);
$rowCount++;
// Iterate through each result from the SQL query in turn
// We fetch each database result row into $row in turn
while ($row = mysqli_fetch_array($result, MYSQL_NUM)) {
for ($i = 0; $i < $columnLenght; $i++) {
$objPHPExcel->getActiveSheet()->SetCellValue($columnArray[$i] . $rowCount, $row[$i]);
}
$rowCount++;

Possibly a duplicate answer but quite useful for me. You can implement the method given below in RecyclerView.Adapter<RecyclerView.ViewHolder>
and can use this method as per your requirements, I hope it will work for you
public void removeItem(@NonNull Object object) {
mDataSetList.remove(object);
notifyDataSetChanged();
}
Winnovative offer a .Net PDF library that supports HTML input. They offer an unlimited free trial. Depending on how you wish to deploy your project, this might be sufficient.

This is the correct syntax for archiving individual; folders in a batch as individual zipped files...
for /d %%X in (*) do "c:\Program Files\7-Zip\7z.exe" a -mx "%%X.zip" "%%X\*"
You can simply check whether the element length is undefined or not just by using
var theHref = $(obj.mainImg_select).attr('href');
if (theHref){
//get the length here if the element is not undefined
elementLength = theHref.length
// do stuff
} else {
// do other stuff
}
This works for modifying childkey value using JSONObject
.
import used is
import org.json.JSONObject;
ex json:(convert json file to string while giving as input)
{
"parentkey1": "name",
"parentkey2": {
"childkey": "test"
},
}
Code
JSONObject jObject = new JSONObject(String jsoninputfileasstring);
jObject.getJSONObject("parentkey2").put("childkey","data1");
System.out.println(jObject);
output:
{
"parentkey1": "name",
"parentkey2": {
"childkey": "data1"
},
}
Here are all the Rails 4 (ActiveRecord migration) datatypes:
:binary
:boolean
:date
:datetime
:decimal
:float
:integer
:bigint
:primary_key
:references
:string
:text
:time
:timestamp
Source: http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/SchemaStatements.html#method-i-add_column
These are the same as with Rails 3.
If you use PostgreSQL, you can also take advantage of these:
:hstore
:json
:jsonb
:array
:cidr_address
:ip_address
:mac_address
They are stored as strings if you run your app with a not-PostgreSQL database.
Edit, 2016-Sep-19:
There's a lot more postgres specific datatypes in Rails 4 and even more in Rails 5.
I found an add-on for Brackets.io that uses auto-indent called Indentator.
It uses shortcut keys Ctrl + Alt + I
Use this:
double start = 400;
double end = 402;
double random = new Random().nextDouble();
double result = start + (random * (end - start));
System.out.println(result);
EDIT:
new Random().nextDouble()
: randomly generates a number between 0 and 1.
start
: start number, to shift number "to the right"
end - start
: interval. Random gives you from 0% to 100% of this number, because random gives you a number from 0 to 1.
EDIT 2: Tks @daniel and @aaa bbb. My first answer was wrong.
I am using this on PHP 7.2.x, it's working fine for me:
public function make_hash($userStr){
try{
/**
* Used and tested on PHP 7.2x, Salt has been removed manually, it is now added by PHP
*/
return password_hash($userStr, PASSWORD_BCRYPT);
}catch(Exception $exc){
$this->tempVar = $exc->getMessage();
return false;
}
}
and then authenticate the hash with the following function:
public function varify_user($userStr,$hash){
try{
if (password_verify($userStr, $hash)) {
return true;
}
else {
return false;
}
}catch(Exception $exc){
$this->tempVar = $exc->getMessage();
return false;
}
}
Example:
//create hash from user string
$user_password = $obj->make_hash2($user_key);
and to authenticate this hash use the following code:
if($obj->varify_user($key, $user_key)){
//this is correct, you can proceed with
}
That's all.
Add the following values to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion Add: DWORD ForceLog set value to 1 DWORD LogFailures set value to 1 DWORD LogResourceBinds set value to 1 DWORD EnableLog set value to 1 String LogPath set value to folder for logs (e.g. C:\FusionLog\)
Make sure you include the backslash after the folder name and that the Folder exists.
You need to restart the program that you're running to force it to read those registry settings.
By the way, don't forget to turn off fusion logging when not needed.

break;
case 1:
intent = new Intent(Activity.this,secondActivity.class);
break;
case 2:

I can't tell you how this is possible with classes, but functions can delete themselves.
def kill_self(exit_msg = 'killed'):
global kill_self
del kill_self
return exit_msg
And see the output:
>>> kill_self
<function kill_self at 0x02A2C780>
>>> kill_self()
'killed'
>>> kill_self
Traceback (most recent call last):
File "<pyshell#28>", line 1, in <module>
kill_self
NameError: name 'kill_self' is not defined
I don't think that deleting an individual instance of a class without knowing the name of it is possible.
NOTE: If you assign another name to the function, the other name will still reference the old one, but will cause errors once you attempt to run it:
>>> x = kill_self
>>> kill_self()
>>> kill_self
NameError: name 'kill_self' is not defined
>>> x
<function kill_self at 0x...>
>>> x()
NameError: global name 'kill_self' is not defined
A single star means that the variable 'a' will be a tuple of extra parameters that were supplied to the function. The double star means the variable 'kw' will be a variable-size dictionary of extra parameters that were supplied with keywords.
Although the actual behavior is spec'd out, it still sometimes can be very non-intuitive. Writing some sample functions and calling them with various parameter styles may help you understand what is allowed and what the results are.
def f0(a)
def f1(*a)
def f2(**a)
def f3(*a, **b)
etc...
I know this is an old question, but I thought I'd add my two cents anyway:
It depends on what the link is going to do, but usually, I would be pointing the link at a url that could possibly be displaying/doing the same thing, for example, if you're making a little about box pop up:
<a id="about" href="/about">About</a>
Then with jQuery
$('#about').click(function(e) {
$('#aboutbox').show();
e.preventDefault();
});
This way, very old browsers (or browsers with JavaScript disabled) can still navigate to a separate about page, but more importantly, Google will also pick this up and crawl the contents of the about page.
np.asscalar(a)
is deprecated since NumPy v1.16, use a.item()
instead.
For example:
a = np.array([[0.6813]])
print(a.item())
gives:
0.6813
There's no built in type for ConcurrentHashSet
because you can always derive a set from a map. Since there are many types of maps, you use a method to produce a set from a given map (or map class).
Prior to Java 8, you produce a concurrent hash set backed by a concurrent hash map, by using Collections.newSetFromMap(map)
In Java 8 (pointed out by @Matt), you can get a concurrent hash set view via ConcurrentHashMap.newKeySet()
. This is a bit simpler than the old newSetFromMap
which required you to pass in an empty map object. But it is specific to ConcurrentHashMap
.
Anyway, the Java designers could have created a new set interface every time a new map interface was created, but that pattern would be impossible to enforce when third parties create their own maps. It is better to have the static methods that derive new sets; that approach always works, even when you create your own map implementations.
As mentioned above, N4113 is the final solution to this matter, but we'll have to wait more than a year to see it coming out.
Meanwhile, if you want such feature, you'll need to resort to "simple" templates and some preprocessor magic.
template<typename T>
class Enum final
{
const char* m_name;
const T m_value;
static T m_counter;
public:
Enum(const char* str, T init = m_counter) : m_name(str), m_value(init) {m_counter = (init + 1);}
const T value() const {return m_value;}
const char* name() const {return m_name;}
};
template<typename T>
T Enum<T>::m_counter = 0;
#define ENUM_TYPE(x) using Enum = Enum<x>;
#define ENUM_DECL(x,...) x(#x,##__VA_ARGS__)
#define ENUM(...) const Enum ENUM_DECL(__VA_ARGS__);
#include <iostream>

namespace Level
{
ENUM_TYPE(std::uint8)
ENUM(OFF)
ENUM(SEVERE)
ENUM(WARNING)
ENUM(INFO, 10)
ENUM(DEBUG)
ENUM(ALL)
}
namespace Example
{
ENUM_TYPE(long)
ENUM(A)
ENUM(B)
ENUM(C, 20)
ENUM(D)
ENUM(E)
ENUM(F)
}
int main(int argc, char** argv)
{
Level::Enum lvl = Level::WARNING;
Example::Enum ex = Example::C;
std::cout << lvl.value() << std::endl; //2
std::cout << ex.value() << std::endl; //20
}
Enum<T>::m_counter
is set to 0 inside each namespace declaration.
(Could someone point me out where ^^this behaviour^^ is mentioned on the standard?)
The preprocessor magic automates the declaration of enumerators.
enum

probably the onclick
handler should read onclick='hello();'
instead of onclick=hello();
You can try this, it works for me.
<input type="text" onchange="CheckValidAmount(this.value)" name="amount" required>
<script type="text/javascript">
function CheckValidAmount(amount) {
var a = /^(?:\d{1,3}(?:,\d{3})*|\d+)(?:\.\d+)?$/;
if(amount.match(a)){
alert("matches");
}else{
alert("does not match");
}
}
</script>
You can try onload event as well;
var createIframe = function (src) {
var self = this;
$('<iframe>', {
src: src,
id: 'iframeId',
frameborder: 1,
scrolling: 'no',
onload: function () {
self.isIframeLoaded = true;
console.log('loaded!');
}
}).appendTo('#iframeContainer');
};
this method helped me.

In AngularJS, we update our models, and our views/templates update the DOM "automatically" (via built-in or custom directives).
$apply and $watch, both being Scope methods, are not related to the DOM.
The Concepts page (section "Runtime") has a pretty good explanation of the $digest loop, $apply, the $evalAsync queue and the $watch list. Here's the picture that accompanies the text:
Whatever code has access to a scope – normally controllers and directives (their link functions and/or their controllers) – can set up a "watchExpression" that AngularJS will evaluate against that scope. This evaluation happens whenever AngularJS enters its $digest loop (in particular, the "$watch list" loop). You can watch individual scope properties, you can define a function to watch two properties together, you can watch the length of an array, etc.
When things happen "inside AngularJS" – e.g., you type into a textbox that has AngularJS two-way databinding enabled (i.e., uses ng-model), an $http callback fires, etc. – $apply has already been called, so we're inside the "AngularJS" rectangle in the figure above. All watchExpressions will be evaluated (possibly more than once – until no further changes are detected).
When things happen "outside AngularJS" – e.g., you used bind() in a directive and then that event fires, resulting in your callback being called, or some jQuery registered callback fires – we're still in the "Native" rectangle. If the callback code modifies anything that any $watch is watching, call $apply to get into the AngularJS rectangle, causing the $digest loop to run, and hence AngularJS will notice the change and do its magic.
You can't have a dict with duplicate keys for definition! Instead you can use a single key and, as value, a list of elements that had that key.
So you can follow these steps:
Well, there is no shortcut to do it as per my findings, but somehow you
an achieve it in few simple steps
First you have to declare a bean of type 'ProtobufJsonFormatHttpMessageConverter'
@Bean
@Primary
public ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {
return new ProtobufJsonFormatHttpMessageConverter(JsonFormat.parser(), JsonFormat.printer());
}
Then you can just write an Utility class like ResponseBuilder, because it can parse the request by default but without these changes it can not produce Json response. and then you can write few methods to convert the response types to its related object type.
public static <T> T build(Message message, Class<T> type) {
Printer printer = JsonFormat.printer();
Gson gson = new Gson();
try {
return gson.fromJson(printer.print(message), type);
} catch (JsonSyntaxException | InvalidProtocolBufferException e) {
throw new ApiException(HttpStatus.INTERNAL_SERVER_ERROR, "Response conversion Error", e);
}
}
Then you can call this method from your controller class as last line like -
return ResponseBuilder.build(<returned_service_object>, <Type>);
Hope this will help you to implement protobuf in json format.
Replace
#include "Landing.h"
with
class Landing;
If you still get errors, also post Item.h
, Flight.h
and common.h
EDIT: In response to comment.
You will need to e.g. #include "Landing.h"
from Event.cpp
in order to actually use the class. You just cannot include it from Event.h
Here is one-liner to get absolute path to your Makefile
file using shell syntax:
SHELL := /bin/bash
CWD := $(shell cd -P -- '$(shell dirname -- "$0")' && pwd -P)
And here is version without shell based on @0xff answer:
CWD := $(abspath $(patsubst %/,%,$(dir $(abspath $(lastword $(MAKEFILE_LIST))))))
Test it by printing it, like:
cwd:
@echo $(CWD)
I do nested updates with a reduce search:
Example:
The nested variables in state:
state = {
coords: {
x: 0,
y: 0,
z: 0
}
}
The function:
handleChange = nestedAttr => event => {
const { target: { value } } = event;
const attrs = nestedAttr.split('.');
let stateVar = this.state[attrs[0]];
if(attrs.length>1)
attrs.reduce((a,b,index,arr)=>{
if(index==arr.length-1)
a[b] = value;
else if(a[b]!=null)
return a[b]
else
return a;
},stateVar);
else
stateVar = value;
this.setState({[attrs[0]]: stateVar})
}
Use:
<input
value={this.state.coords.x}
onChange={this.handleTextChange('coords.x')}
/>
First off; best practice would be to get the users Desktop folder with
string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
Then you can find all the files with something like
string[] files = Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories);
Note that with the above line you will find all files with a .txt extension in the Desktop folder of the logged in user AND all subfolders.
Then you could copy or move the files by enumerating the above collection like
// For copying...
foreach (string s in files)
{
File.Copy(s, "C:\newFolder\newFilename.txt");
}
// ... Or for moving
foreach (string s in files)
{
File.Move(s, "C:\newFolder\newFilename.txt");
}
Please note that you will have to include the filename in your Copy()
(or Move()
) operation. So you would have to find a way to determine the filename of at least the extension you are dealing with and not name all the files the same like what would happen in the above example.
With that in mind you could also check out the DirectoryInfo
and FileInfo
classes.
These work in similair ways, but you can get information about your path-/filenames, extensions, etc. more easily
Check out these for more info:

Try this methode to redirect all to homepage new domain, Its works for me:
RewriteCond %{HTTP_HOST} ^olddomain\.com$ [OR]

When spring instantiates beans, it looks for a couple of interfaces like ApplicationContextAware
and InitializingBean
. If they are found, the methods are invoked. E.g. (very simplified)
Class<?> beanClass = beanDefinition.getClass();
Object bean = beanClass.newInstance();
if (bean instanceof ApplicationContextAware) {
((ApplicationContextAware) bean).setApplicationContext(ctx);
}
Note that in newer version it may be better to use annotations, rather than implementing spring-specific interfaces. Now you can simply use:
@Inject // or @Autowired
private ApplicationContext ctx;
I know this is old, but I figured I'd give my input. I had to do this for a project at work and this was my solution.
I have a Building object that includes the Timezone using the TimeZone class and wanted to create zoneId and offset fields in a new class.
So what I did was create:
private String timeZoneId;
private String timeZoneOffset;
Then in the constructor I passed in the Building object and set these fields like so:
this.timeZoneId = building.getTimeZone().getID();
this.timeZoneOffset = building.getTimeZone().toZoneId().getId();
So timeZoneId might equal something like "EST" And timeZoneOffset might equal something like "-05:00"
I would like to not that you might not
In WAMP the files are served by the Apache component (the A in WAMP).
In Apache, by default the files served are located in the subdirectory htdocs
of the installation directory. But this can be changed, and is actually changed when WAMP installs Apache.
The location from where the files are served is named the DocumentRoot
, and is defined using a variable in Apache configuration file. The default value is the subdirectory htdocs
relative to what is named the ServerRoot
directory.
By default the ServerRoot
is the installation directory of Apache. However this can also be redefined into the configuration file, or using the -d
option of the command httpd
which is used to launch Apache. The value in the configuration file overrides the -d
option.
The configuration file is by default conf/httpd.conf
relative to ServerRoot
. But this can be changed using the -f
option of command httpd.
When WAMP installs itself, it modify the default configuration file with DocumentRoot c:/wamp/www/
. The files to be served need to be located here and not in the htdocs
default directory.
You may change this location set by WAMP, either by modifying DocumentRoot
in the default configuration file, or by using one of the two command line options -f
or -d
which point explicitly or implicity to a new configuration file which may hold a different value for DocumentRoot
(in that case the new file needs to contain this definition, but also the rest of the configuration found in the default configuration file).
For me, to make it work I need to encode hex value of space within CDATA xml element, so that post parsing it adds up just as in the htm webgae & when viewed in browser just displays a space!. ( all above ideas & answers are useful )

You can set the default authenticator for http requests like this:
Authenticator.setDefault (new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication ("username", "password".toCharArray());
}
});
Also, if you require more flexibility, you can check out the Apache HttpClient, which will give you more authentication options (as well as session support, etc.)
First of all, as @AndrewFinnell and @KenLiu point out, in SVN the directory names themselves mean nothing -- "trunk, branches and tags" are simply a common convention that is used by most repositories. Not all projects use all of the directories (it's reasonably common not to use "tags" at all), and in fact, nothing is stopping you from calling them anything you'd like, though breaking convention is often confusing.
I'll describe probably the most common usage scenario of branches and tags, and give an example scenario of how they are used.
Trunk: The main development area. This is where your next major release of the code lives, and generally has all the newest features.
Branches: Every time you release a major version, it gets a branch created. This allows you to do bug fixes and make a new release without having to release the newest - possibly unfinished or untested - features.
Tags: Every time you release a version (final release, release candidates (RC), and betas) you make a tag for it. This gives you a point-in-time copy of the code as it was at that state, allowing you to go back and reproduce any bugs if necessary in a past version, or re-release a past version exactly as it was. Branches and tags in SVN are lightweight - on the server, it does not make a full copy of the files, just a marker saying "these files were copied at this revision" that only takes up a few bytes. With this in mind, you should never be concerned about creating a tag for any released code. As I said earlier, tags are often omitted and instead, a changelog or other document clarifies the revision number when a release is made.
For example, let's say you start a new project. You start working in "trunk", on what will eventually be released as version 1.0.
Once 1.0.0 is finished, you branch trunk into a new "1.0" branch, and create a "1.0.0" tag. Now work on what will eventually be 1.1 continues in trunk.
You come across some bugs in the code, and fix them in trunk, and then merge the fixes over to the 1.0 branch. You can also do the opposite, and fix the bugs in the 1.0 branch and then merge them back to trunk, but commonly projects stick with merging one-way only to lessen the chance of missing something. Sometimes a bug can only be fixed in 1.0 because it is obsolete in 1.1. It doesn't really matter: you only want to make sure that you don't release 1.1 with the same bugs that have been fixed in 1.0.
Once you find enough bugs (or maybe one critical bug), you decide to do a 1.0.1 release. So you make a tag "1.0.1" from the 1.0 branch, and release the code. At this point, trunk will contain what will be 1.1, and the "1.0" branch contains 1.0.1 code. The next time you release an update to 1.0, it would be 1.0.2.
Eventually you are almost ready to release 1.1, but you want to do a beta first. In this case, you likely do a "1.1" branch, and a "1.1beta1" tag. Now, work on what will be 1.2 (or 2.0 maybe) continues in trunk, but work on 1.1 continues in the "1.1" branch.
Once you release 1.1 final, you do a "1.1" tag from the "1.1" branch.
You can also continue to maintain 1.0 if you'd like, porting bug fixes between all three branches (1.0, 1.1, and trunk). The important takeaway is that for every main version of the software you are maintaining, you have a branch that contains the latest version of code for that version.
Another use of branches is for features. This is where you branch trunk (or one of your release branches) and work on a new feature in isolation. Once the feature is completed, you merge it back in and remove the branch.
The idea of this is when you're working on something disruptive (that would hold up or interfere with other people from doing their work), something experimental (that may not even make it in), or possibly just something that takes a long time (and you're afraid if it holding up a 1.2 release when you're ready to branch 1.2 from trunk), you can do it in isolation in branch. Generally you keep it up to date with trunk by merging changes into it all the time, which makes it easier to re-integrate (merge back to trunk) when you're finished.
Also note, the versioning scheme I used here is just one of many. Some teams would do bug fix/maintenance releases as 1.1, 1.2, etc., and major changes as 1.x, 2.x, etc. The usage here is the same, but you may name the branch "1" or "1.x" instead of "1.0" or "1.0.x". (Aside, semantic versioning is a good guide on how to do version numbers).

Problem solved!
Recently, AWS added a feature called Sessions Manager to the Systems Manager service that allows one to SSH into an instance without needing to setup a private key or opening up port 22. I believe authentication is done with IAM and optionally MFA.
You can find out more about it here:
My coworkers helped me with this:
select CONVERT(VARCHAR(10), <tms_column>, 112), count(*)
from table where <tms_column> > '2012-09-10'
group by CONVERT(VARCHAR(10), <tms_column>, 112);
or
select CONVERT(DATE, <tms_column>, 112), count(*)
from table where <tms_column> > '2012-09-10'
group by CONVERT(DATE, <tms_column>, 112);
If you want to do this in PHP:
// replace time() with the time stamp you want to add one day to
$startDate = time();
date('Y-m-d H:i:s', strtotime('+1 day', $startDate));
If you want to add the date in MySQL:
-- replace CURRENT_DATE with the date you want to add one day to
SELECT DATE_ADD(CURRENT_DATE, INTERVAL 1 DAY);
You could do this with the CSS3 :target selector.
menu:hover block {
visibility: visible;
}
block:target {
visibility:hidden;
}
I noticed in the Android source that almost every operation forces the Bundle to unparcel its data. So if (like me) you need to do this frequently for debugging purposes, the below is very quick to type:
Bundle extras = getIntent().getExtras();
extras.isEmpty(); // unparcel
System.out.println(extras);
The simplest way to extract a number from a string is to use regular expressions and findall
.
>>> import re
>>> s = '300 gm'
>>> re.findall('\d+', s)
['300']
>>> s = '300 gm 200 kgm some more stuff a number: 439843'
>>> re.findall('\d+', s)
['300', '200', '439843']
It might be that you need something more complex, but this is a good first step.
Note that you'll still have to call int
on the result to get a proper numeric type (rather than another string):
>>> map(int, re.findall('\d+', s))
[300, 200, 439843]
The following can be used to remove only multi blank lines (reduce them to a single blank line) and leaving single blank lines intact:
:g/^\_$\n\_^$/d
If someone is interested in the similar problem, but is not working with XAML, here's my solution:
var B1 = new Border();
B1.BorderBrush = Brushes.Black;
B1.BorderThickness = new Thickness(0, 1, 0, 0); // You can specify here which borders do you want
YourPanel.Children.Add(B1);
"BypassTraverseChecking" means that you can directly access any deep-level subdirectory even if you don't have all the intermediary access privileges to directories in between, i.e. all directories above it towards root level .
You're probably passing null
value if you're loading the coordinates dynamically, set a check before you call the map loader ie: if(mapCords){loadMap}
find . -type d > list.txt
Will list all directories and subdirectories under the current path. If you want to list all of the directories under a path other than the current one, change the .
to that other path.
If you want to exclude certain directories, you can filter them out with a negative condition:
find . -type d ! -name "~snapshot" > list.txt
don't use recursive approach (heap issues) :) use a queue
queue.add(param_dir)
while (queue is not empty){
directory= queue.pop
- get items from current directory
- if item is file add to a list (final list)
- if item is directory => queue.push
}
that was easy, enjoy!
This seems as good a place as any to document another possible reason for the infamous PKIX error message. After spending far too long looking at the keystore and truststore contents and various java installation configs I realised that my issue was down to... a typo.
The typo meant that I was also using the keystore as the truststore. As my companies Root CA was not defined as a standalone cert in the keystore but only as part of a cert chain, and was not defined anywhere else (i.e. cacerts) I kept getting the PKIX error.
After a failed release (this is prod config, it was ok elsewhere) and two days of head scratching I finally saw the typo, and now all is good.
Hope this helps someone.
Suprised no-one has yet mentioned the recommended solution in the Python 3 docs:
See also:
- The linspace recipe shows how to implement a lazy version of range that suitable for floating point applications.
Once defined, the recipe is easy to use and does not require numpy
or any other external libraries, but functions like numpy.linspace()
. Note that rather than a step
argument, the third num
argument specifies the number of desired values, for example:
print(linspace(0, 10, 5))
# linspace(0, 10, 5)
print(list(linspace(0, 10, 5)))
# [0.0, 2.5, 5.0, 7.5, 10]
I quote a modified version of the full Python 3 recipe from Andrew Barnert below:
import collections.abc
import numbers
class linspace(collections.abc.Sequence):
"""linspace(start, stop, num) -> linspace object
Return a virtual sequence of num numbers from start to stop (inclusive).
If you need a half-open range, use linspace(start, stop, num+1)[:-1].
"""
def __init__(self, start, stop, num):
if not isinstance(num, numbers.Integral) or num <= 1:
raise ValueError('num must be an integer > 1')
self.start, self.stop, self.num = start, stop, num
self.step = (stop-start)/(num-1)
def __len__(self):
return self.num
def __getitem__(self, i):
if isinstance(i, slice):
return [self[x] for x in range(*i.indices(len(self)))]
if i < 0:
i = self.num + i
if i >= self.num:
raise IndexError('linspace object index out of range')
if i == self.num-1:
return self.stop
return self.start + i*self.step
def __repr__(self):
return '{}({}, {}, {})'.format(type(self).__name__,
self.start, self.stop, self.num)
def __eq__(self, other):
if not isinstance(other, linspace):
return False
return ((self.start, self.stop, self.num) ==
(other.start, other.stop, other.num))
def __ne__(self, other):
return not self==other
def __hash__(self):
return hash((type(self), self.start, self.stop, self.num))
You cannot do using JDBC as it does not support . Work around would be including iBatis iBATIS is a persistence framework and call the Scriptrunner
constructor as shown in iBatis documentation .
Its not good to include a heavy weight persistence framework like ibatis in order to run a simple sql scripts any ways which you can do using command line
$ mysql -u root -p db_name < test.sql
You should be able to reference sheets by the user-supplied name. Are you sure you're referencing the correct Workbook? If you have more than one workbook open at the time you refer to a sheet, that could definitely cause the problem.
If this is the problem, using ActiveWorkbook
(the currently active workbook) or ThisWorkbook
(the workbook that contains the macro) should solve it.
For example,
Set someSheet = ActiveWorkbook.Sheets("Custom Sheet")
Python actually makes this quite easy.
Something like
for i in range(10):
print '%-12i%-12i' % (10 ** i, 20 ** i)
will have the output
1 1
10 20
100 400
1000 8000
10000 160000
100000 3200000
1000000 64000000
10000000 1280000000
100000000 25600000000
1000000000 512000000000
The % within the string is essentially an escape character and the characters following it tell python what kind of format the data should have. The % outside and after the string is telling python that you intend to use the previous string as the format string and that the following data should be put into the format specified.
In this case I used "%-12i" twice. To break down each part:
'-' (left align)
'12' (how much space to be given to this part of the output)
'i' (we are printing an integer)
From the docs: https://docs.python.org/2/library/stdtypes.html#string-formatting
You can do this by executing the following command:
ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012
gcc passes a few extra -L paths to the linker, which you can list with the following command:
gcc -print-search-dirs | sed '/^lib/b 1;d;:1;s,/[^/.][^/]*/\.\./,/,;t 1;s,:[^=]*=,:;,;s,;,; ,g' | tr \; \\012
The answers suggesting to use ld.so.conf and ldconfig are not correct because they refer to the paths searched by the runtime dynamic linker (i.e. whenever a program is executed), which is not the same as the path searched by ld (i.e. whenever a program is linked).
I got this from some forum. I hope it will be useful for you.

Your regex ^[0-9]
matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $
to the end:
^[0-9]*$
This accepts any number of digits, including none. To accept one or more digits, change the *
to +
. To accept exactly one digit, just remove the *
.
UPDATE: You mixed up the arguments to IsMatch
. The pattern should be the second argument, not the first:
if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))
CAUTION: In JavaScript, \d
is equivalent to [0-9]
, but in .NET, \d
by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9]
(or supply the RegexOptions.ECMAScript flag).
Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically. You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.
In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:
*/10 * * * * /usr/bin/php /opt/test.php
In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.
*
is a wildcard, meaning "every time".
Start with finding out your PHP binary by typing in command line:
whereis php
The output should be something like:
php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz
Specify correctly the full path in your command.
crontab -e
To see what you got in crontab.

I just had the situation that I wanted this only for lines exceeding \linewidth
, that is: Squeezing long lines slightly.
Since it took me hours to figure this out, I would like to add it here.
I want to emphasize that scaling fonts in LaTeX is a deadly sin! In nearly every situation, there is a better way (e.g.
multline
of themathtools
package). So use it conscious.
In this particular case, I had no influence on the code base apart the preamble and some lines slightly overshooting the page border when I compiled it as an eBook-scaled pdf.

1st Way:
string[] folders = Directory.GetDirectories(path, "*", SearchOption.TopDirectoryOnly);
string jsonString = JsonConvert.SerializeObject(folders);
2nd Way:
string[] folders = new DirectoryInfo(yourPath).GetDirectories().Select(d => d.Name).ToArray();
3rd Way:
string[] folders =
new DirectoryInfo(yourPath).GetDirectories().Select(delegate(DirectoryInfo di)
{
return di.Name;

Place the commandName
in .aspx page
<asp:Button ID="btnDelete" Text="Delete" runat="server" CssClass="CoolButtons" CommandName="DeleteData"/>
Subscribe the rowCommand
event for the grid and you can try like this,
protected void grdBillingdata_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "DeleteData")
{
GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer);
HiddenField hdnDataId = (HiddenField)row.FindControl("hdnDataId");
}
}
This should do it:
<%= f.select :project_id, @project_select, :selected => params[:pid] %>
Or, simply use the headers property introduced in 1.5:
headers: {"Authorization": "Basic xxxx"}

For smaller files you could use this:
& C:\windows\system32\more +1 oldfile.csv > newfile.csv | out-null
... but it's not very effective at processing my example file of 16MB. It doesn't seem to terminate and release the lock on newfile.csv.
Assuming you are calling this in an Activity class
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);
The first parameter, Resources, is required. It is normally obtainable in any Context (and subclasses like Activity).

when we pass vector by value in a function as an argument,it simply creates the copy of vector and no any effect happens on the vector which is defined in main function when we call that particular function. while when we pass vector by reference whatever is written in that particular function, every action will going to perform on the vector which is defined in main or other function when we call that particular function.
You are wrong. There is one way to kill an application. In a class with super class Application, we use some field, for example, killApp
. When we start the splash screen (first activity) in onResume()
, we set a parameter for false for field killApp
. In every activity which we have when onResume()
is called in the end, we call something like that:
if(AppClass.killApp())
finish();
Every activity which is getting to the screen have to call onResume()
. When it is called, we have to check if our field killApp
is true. If it is true, current activities call finish()
. To invoke the full action, we use the next construction. For example, in the action for a button:
AppClass.setkillApplication(true);
finish();
return;
Even i ran into the same issue with mysql and liquibase. So this is what the problem is: The table from which you want to reference a column of other table is different either in case of datatype or in terms of size of the datatype.
Error appears in below scenario:
Scenario 1:
Table A has column id, type=bigint
Table B column referenced_id type varchar(this column gets the value from the id column of Table A.)
Liquibase changeset for table B:
<changeset id="XXXXXXXXXXX-1" author="xyz">
<column name="referenced_id" **type="varchar"**>
</column>
</changeset>
<changeSet id="XXXXXXXXXXX-2" author="xyz">
<addForeignKeyConstraint constraintName="FK_table_A"
referencedTableName="A" **baseColumnNames="referenced_id**"
referencedColumnNames="id" baseTableName="B" />
</changeSet>
Table A changeSet:
<changeSet id="YYYYYYYYYY" author="xyz">
<column **name="id"** **type="bigint"** autoIncrement="${autoIncrement}">
<constraints primaryKey="true" nullable="false"/>
</column>
</changeSet>
Solution:
correct the type of table B to bigint because the referenced table has type bigint.
Scenrario 2:
The type might be correct but the size might not.
e.g. :
Table B : referenced column type="varchar 50"
Table A : base column type ="varchar 255"
Solution change the size of referenced column to that of base table's column size.

Need an edge-to-edge design? Drop the parent
.container

.
Still if you need to remove padding from .row
and immediate child columns you have to add the class .no-gutters

To change color of SVG element I have found out a way while inspecting Google search box search icon below:
.search_icon {
color: red;
fill: currentColor;
display: inline-block;
width: 100px;
height: 100px;
}
_x000D_
<span class="search_icon">
<svg focusable="false" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M15.5 14h-.79l-.28-.27A6.471 6.471 0 0 0 16 9.5 6.5 6.5 0 1 0 9.5 16c1.61 0 3.09-.59 4.23-1.57l.27.28v.79l5 4.99L20.49 19l-4.99-5zm-6 0C7.01 14 5 11.99 5 9.5S7.01 5 9.5 5 14 7.01 14 9.5 11.99 14 9.5 14z"></path></svg>

I have used span element with "display:inline-block", height, width and setting a particular style "color: red; fill: currentColor;" to that span tag which is inherited by the child svg element.
You could just use the imageView's image cache. It will render the entire view as it is layed out (scaled,bordered with a background etc) to a new bitmap.
just make sure it built.
imageView.buildDrawingCache();
Bitmap bmap = imageView.getDrawingCache();
there's your bitmap as the screen saw it.
I had a similar but it was dealing with dates. Query to show all items for the last month, works great without conditions until Jan. In order for it work correctly, needed to add a year and month variable
declare @yr int
declare @mth int
set @yr=(select case when month(getdate())=1 then YEAR(getdate())-1 else YEAR(getdate())end)
set @mth=(select case when month(getdate())=1 then month(getdate())+11 else month(getdate())end)
Now I just add the variable into condition: ...
(year(CreationTime)=@yr and MONTH(creationtime)=@mth)
input[type='checkbox', name='ProductCode']
That's the CSS way and I'm almost sure it will work in jQuery.
Just use CR to go to beginning of the line.
import time
for x in range (0,5):
b = "Loading" + "." * x
print (b, end="\r")

ALTER TABLE foobar_data MODIFY COLUMN col VARCHAR(255) NOT NULL DEFAULT '{}';

It looks like you're close. Assuming that it's not just a typo in your submission, step 3 should be cd repo2
instead of repo1. And step 6 should be git pull
not push. Reworked list:
1. git clone repo1
2. git clone repo2
3. cd repo2
4. git remote rm origin
5. git remote add repo1
6. git pull
7. git remote rm repo1
8. git remote add newremote
I ran into the same situation where commands such as git diff origin
or git diff origin master
produced the error reported in the question, namely Fatal: ambiguous argument...
To resolve the situation, I ran the command
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master
to set refs/remotes/origin/HEAD to point to the origin/master branch.
Before running this command, the output of git branch -a
was:
* master
remotes/origin/master
After running the command, the error no longer happened and the output of git branch -a
was:
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
(Other answers have already identified that the source of the error is HEAD not being set for origin. But I thought it helpful to provide a command which may be used to fix the error in question, although it may be obvious to some users.)
Additional information:
For anybody inclined to experiment and go back and forth between setting and unsetting refs/remotes/origin/HEAD, here are some examples.
To unset:
git remote set-head origin --delete
To set:
(additional ways, besides the way shown at the start of this answer)
git remote set-head origin master
to set origin/head explicitly
OR
git remote set-head origin --auto
to query the remote and automatically set origin/HEAD to the remote's current branch.
References:
git remote --help
see set-head descriptiongit symbolic-ref --help
Just an alternative:
ls -lAR | grep -v '^d' | awk '{total += $5} END {print "Total:", total}'
grep -v '^d'
will exclude the directories.
The brackets are required if you use keywords or special chars in the column names or identifiers. You could name a column [First Name]
(with a space)--but then you'd need to use brackets every time you referred to that column.
The newer tools add them everywhere just in case or for consistency.

You can use html
instead of text
and replace each occurrence of \n
with <br>
. You will have to correctly escape your text though.
x = x.replace(/&/g, '&')
.replace(/>/g, '>')
.replace(/</g, '<')
.replace(/\n/g, '<br>');
This can also be done with a regular expression
import re
input = " Hello "
output = re.sub(r'^\s+|\s+$', '', input)
# output = 'Hello'
On Oracle Linux 7.x running PHP version 7.3.x you need to run sudo yum install php-mysqlnd

Remember to restart PHP and or your server for the changes to take effect.
It happens that /etc/hosts
file doesn't support wild card entries.
You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf

Here is a fully functional example of what you are trying to accomplish. I created the example inside of hyperdev rather than jsFiddle so that you could see the server-side and client-side code.
View Code: https://hyperdev.com/#!/project/destiny-authorization
View Working Application: https://destiny-authorization.hyperdev.space/
This code creates a handler for a get request that returns a random string:
app.get("/string", function(req, res) {
var strings = ["string1", "string2", "string3"]
var n = Math.floor(Math.random() * strings.length)
res.send(strings[n])
});
This jQuery code then makes the ajax request and receives the random string from the server.
$.get("/string", function(string) {
$('#txtString').val(string);
});
Note that this example is based on code from Jamund Ferguson's answer so if you find this useful be sure to upvote him as well. I just thought this example would help you to see how everything fits together.
Can you just add a little more logic into your overscroll disabling code to make sure the targeted element in question is not one that you would like to scroll? Something like this:
document.body.addEventListener('touchmove',function(e){
if(!$(e.target).hasClass("scrollable")) {
e.preventDefault();
}
});
Try this way:
<%= f.select(:object_field, ['Item 1', ...], {}, { :class => 'my_style_class' }) %>
select
helper takes two options hashes, one for select, and the second for html options. So all you need is to give default empty options as first param after list of items and then add your class to html_options
.

You don't need to wrap everything in a DIV to achieve basic styling on inputs.
input[type="text"] {margin: 0 0 10px 0;}
will do the trick in most cases.
Semantically, one <br/> tag is okay between elements to position them. When you find yourself using multiple <br/>'s (which are semantic elements) to achieve cosmetic effects, that's a flag that you're mixing responsibilities, and you should consider getting back to basics.
In my case it was more of a Microsoft bug, than an actual issue. I installed under the Administrator login and used strong password btw but I was still getting this error constantly.
I tried to install with Windows credential without entering the password, but that did not go through either. Was getting the same error.
Then I cleared all password textboxes manually and copies the correct password in each text box. Hit enter, and it went through.
The error was most likely misleading.
There are two types of drop down lists available (I am not sure since which version).
ActiveX Drop Down
You can set the column widths, so your hidden column can be set to 0.
Form Drop Down
You could set the drop down range to a hidden sheet and reference the cell adjacent to the selected item. This would also work with the ActiveX type control.

PYTHONPATH
only affects import
statements, not the top-level Python interpreter's lookup of python files given as arguments.
Needing PYTHONPATH
to be set is not a great idea - as with anything dependent on environment variables, replicating things consistently across different machines gets tricky. Better is to use Python 'packages' which can be installed (using 'pip', or distutils) in system-dependent paths which Python already knows about.
Have a read of https://the-hitchhikers-guide-to-packaging.readthedocs.org/en/latest/ - 'The Hitchhiker's Guide to Packaging', and also http://docs.python.org/3/tutorial/modules.html - which explains PYTHONPATH and packages at a lower level.

const data = [_x000D_
{ name: 'Mike', speciality: 'JS', age: 22 },_x000D_
{ name: 'Tom', speciality: 'Java', age: 30 },_x000D_
{ name: 'Mike', speciality: 'PHP', age: 40 },_x000D_
{ name: 'Abby', speciality: 'Design', age: 20 },_x000D_
]_x000D_
_x000D_
const sorted = multisort(data, criteria)_x000D_
_x000D_
console.log(sorted)

This library more mutch powerful, that was my case. Try it.
You should try slicing the image if possible into a smaller piece which could be repeated. I have sliced that image to a 101x101px image.
CSS:
body{
background-image: url(SO_texture_bg.jpg);
background-repeat:repeat;
}
But in some cases, we wouldn't be able to slice the image to a smaller one. In that case, I would use the whole image. But you could also use the CSS3 methods like what Mustafa Kamal had mentioned.
Wish you good luck.
This solve my problem.

if you have Internet Explorer 11 and it's running over a touch screen pc, you must use: preg_match('/Trident/7.0; Touch; rv:11.0/', $_SERVER['HTTP_USER_AGENT']) instead of: preg_match('/Trident/7.0; rv:11.0/', $_SERVER['HTTP_USER_AGENT'])
The code below gives the HEX and RGB value of the range whether formatted using conditional formatting or otherwise. If the range is not formatted using Conditional Formatting and you intend to use iColor function in the Excel as UDF. It won't work. Read the below excerpt from MSDN.
Note that the DisplayFormat property does not work in user defined functions. For example, in a worksheet function that returns the interior color of a cell, if you use a line similar to:
Range.DisplayFormat.Interior.ColorIndex
then the worksheet function executes to return a #VALUE! error. If you are not finding color of the conditionally formatted range, then I encourage you to rather use
Range.Interior.ColorIndex
as then the function can also be used as UDF in Excel. Such as iColor(B1,"HEX")
Public Function iColor(rng As Range, Optional formatType As String) As Variant
'formatType: Hex for #RRGGBB, RGB for (R, G, B) and IDX for VBA Color Index
Dim colorVal As Variant
colorVal = rng.DisplayFormat.Interior.Color
Select Case UCase(formatType)
Case "HEX"
iColor = "#" & Format(Hex(colorVal Mod 256),"00") & _
Format(Hex((colorVal \ 256) Mod 256),"00") & _
Format(Hex((colorVal \ 65536)),"00")
Case "RGB"
iColor = Format((colorVal Mod 256),"00") & ", " & _
Format(((colorVal \ 256) Mod 256),"00") & ", " & _
Format((colorVal \ 65536),"00")
Case "IDX"
iColor = rng.Interior.ColorIndex
Case Else
iColor = colorVal
End Select
End Function
'Example use of the iColor function
Sub Get_Color_Format()
Dim rng As Range
For Each rng In Selection.Cells
rng.Offset(0, 1).Value = iColor(rng, "HEX")
rng.Offset(0, 2).Value = iColor(rng, "RGB")

Even with openssl v1.1.0 I had some problems passing our proxy, e.g. s_client: HTTP CONNECT failed: 400 Bad Request
That forced me to write a minimal Java-class to show the SSL-Handshake
public static void main(String[] args) throws IOException, URISyntaxException {
HttpHost proxy = new HttpHost("proxy.my.company", 8080);
DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
CloseableHttpClient httpclient = HttpClients.custom()
.setRoutePlanner(routePlanner)
.build();
URI uri = new URIBuilder()
.setScheme("https")
.setHost("www.myhost.com")
.build();
HttpGet httpget = new HttpGet(uri);
httpclient.execute(httpget);
}
With following dependency:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.2</version>
<type>jar</type>
</dependency>
you can run it with Java SSL Logging turned on

You do not need to keep the system images unless you want to use the emulator on your desktop. Along with it you can remove other unwanted stuff to clear disk space.
Adding as an answer to my own question as I've had to narrate this to people in my team more than a few times. Hence this answer as a reference to share with other curious ones.
In the last few weeks there were several colleagues who asked me how to safely get rid of the unwanted stuff to release disk space (most of them were beginners). I redirected them to this question but they came back to me for steps. So for android beginners here is a step by step guide to safely remove unwanted stuff.
Note
First, be sure you are not going to use emulators and will always do you development on a physical device. In case you are going to need emulators, note down the API Levels and type of emulators you'll need. Do not remove those. For the rest follow the below steps:
Steps to safely clear up unwanted stuff from Android SDK folder on the disk
- Open the Stand Alone Android SDK Manager. To open do one of the following:
.
- Uncheck all items ending with "System Image". Each API Level will have more than a few. In case you need some and have figured the list already leave them checked to avoid losing them and having to re-download.
.
- Optional (may help save a marginally more amount of disk space): To free up some more space, you can also entirely uncheck unrequired API levels. Be careful again to avoid re-downloading something you are actually using in other projects.
.
- In the end make sure you have at least the following (check image below) for the remaining API levels to be able to seamlessly work with your physical device.
In the end the clean android sdk installed components should look something like this in the SDK manager.
gradle build -x test --parallel
If your machine has multiple cores. However, it is not recommended to use parallel clean.
Others already answered your question as stated, but I find that I usually want to execute the lines that I just wrote. for that, CtrlAltx in the lisp works just fine.
You need a Flask view that will receive POST data and an HTML form that will send it.
from flask import request
@app.route('/addRegion', methods=['POST'])
def addRegion():
...
return (request.form['projectFilePath'])
<form action="{{ url_for('addRegion') }}" method="post">
Project file path: <input type="text" name="projectFilePath"><br>
<input type="submit" value="Submit">
</form>
This error occurs mainly when copy-pasting the code. Try editing/replacing minus(-), bracket({) symbols.

According to git push
documentation:
git push origin HEAD
A handy way to push the current branch to the same name on the remote.
So I think what you need is git push origin HEAD
. Also it can be useful git push -u origin HEAD
to set upstream tracking information in the local branch, if you haven't already pushed to the origin.
From Sort an array of associative arrays by value of given key in php:
by using usort (http://php.net/usort) , we can sort an array in ascending and descending order. just we need to create a function and pass it as parameter in usort. As per below example used greater than for ascending order if we passed less than condition then it's sort in descending order. Example :
$array = array(
array('price'=>'1000.50','product'=>'test1'),
array('price'=>'8800.50','product'=>'test2'),
array('price'=>'200.0','product'=>'test3')
);
function cmp($a, $b) {
return $a['price'] > $b['price'];
}
usort($array, "cmp");
print_r($array);
Output:
Array
(
[0] => Array
(
[price] => 200.0
[product] => test3
)
[1] => Array
(
[price] => 1000.50
[product] => test1
)
[2] => Array
(
[price] => 8800.50
[product] => test2
)
)

To send HTML contents in the body of the mail on the go with Sender and Recipient mail address in single line, you may try the below,
export EMAIL="[email protected]" && mutt -e "my_hdr Content-Type: text/html" -s "Test Mail" "[email protected]" < body_html.html
File: body_html.html
<HTML>
<HEAD> Test Mail </HEAD>
<BODY>
<p>This is a <strong><span style="color: #ff0000;">test mail!</span></strong></p>
</BODY>

Note: Tested in RHEL, CentOS, Ubuntu.
The use is more obvious if you don't use 'SELECT *' (which is a bad habit you should get out of):
SELECT t1.colA, t2.colB, t3.colC FROM alongtablename AS t1, anotherlongtablename AS t2, yetanotherlongtablename AS t3 WHERE t1.colD = t2.colE...
This script will resize an image (somepic.jpg) using PIL (Python Imaging Library) to a width of 300 pixels and a height proportional to the new width. It does this by determining what percentage 300 pixels is of the original width (img.size[0]) and then multiplying the original height (img.size[1]) by that percentage. Change "basewidth" to any other number to change the default width of your images.
from PIL import Image
basewidth = 300
img = Image.open('somepic.jpg')
wpercent = (basewidth/float(img.size[0]))
hsize = int((float(img.size[1])*float(wpercent)))
img = img.resize((basewidth,hsize), Image.ANTIALIAS)
img.save('somepic.jpg')
If you load a page in your browser using HTTPS, the browser will refuse to load any resources over HTTP. As you've tried, changing the API URL to have HTTPS instead of HTTP typically resolves this issue. However, your API must not allow for HTTPS connections. Because of this, you must either force HTTP on the main page or request that they allow HTTPS connections.
Note on this: The request will still work if you go to the API URL instead of attempting to load it with AJAX. This is because the browser is not loading a resource from within a secured page, instead it's loading an insecure page and it's accepting that. In order for it to be available through AJAX, though, the protocols should match.
Hi, this will throw an error:
foreach ($product->sku as $sku){
// Code Here
}
because you cannot loop a model with a specific column ($product->sku) from the table.
So you must loop on the whole model:
foreach ($product as $p) {
// code
}
Inside the loop you can retrieve whatever column you want just adding "->[column_name]"
foreach ($product as $p) {
echo $p->sku;
}
Have a great day
For some reason, some of the other methods don't work until the field has been focused/blured/changed, or a submit has been attempted... this works for me.
$("#formid").data('validator').element('#element').valid();
Had to dig through the jquery.validate script to find it...
A war file is just a zip file with a specific directory structure. So you can use unzip or the jar tool for unzipping.
But you probably don't want to do that. If you add the war file into the webapps directory of Tomcat the Tomcat will take care of extracting/installing the war file.
If you are utilizing arrays too much then you should include cstring.h
because it has too many functions including finding substrings.
If you can't change server media-type response, you can extend GsonHttpMessageConverter to process additional support types
public class MyGsonHttpMessageConverter extends GsonHttpMessageConverter {
public MyGsonHttpMessageConverter() {
List<MediaType> types = Arrays.asList(
new MediaType("text", "html", DEFAULT_CHARSET),
new MediaType("application", "json", DEFAULT_CHARSET),
new MediaType("application", "*+json", DEFAULT_CHARSET)
);
super.setSupportedMediaTypes(types);
}
}
Do not disable expected browser behaviour.
Make your pages handle the possibility of users going back a page or two; don't try to cripple their software.
The data dictionary table DBA_SYNONYMS
has information about all the synonyms in a database. So you can run the query
SELECT table_owner, table_name, db_link
FROM dba_synonyms
WHERE owner = 'PUBLIC'
AND synonym_name = <<synonym name>>
to see what the public synonym currently points at.
Well, I can think of a CSS hack that will resolve this issue.
You could add the following line in your CSS file:
* html .blog_list div.postbody img { width:75px; height: SpecifyHeightHere; }
The above code will only be seen by IE6. The aspect ratio won't be perfect, but you could make it look somewhat normal. If you really wanted to make it perfect, you would need to write some javascript that would read the original picture width, and set the ratio accordingly to specify a height.

I was looking for a way to do this myself without adding an extra dependency to the classpath. After some investigation I found that it is possible as long as you have a generic supertype. This was OK for me as I was working with a DAO layer with a generic layer supertype. If this fits your scenario then it's the neatest approach IMHO.
Most generics use cases I've come across have some kind of generic supertype e.g. List<T>
for ArrayList<T>
or GenericDAO<T>
for DAO<T>
, etc.
The article Accessing generic types at runtime in Java explains how you can do it using pure Java.
@SuppressWarnings("unchecked")
public GenericJpaDao() {
this.entityBeanType = ((Class) ((ParameterizedType) getClass()
.getGenericSuperclass()).getActualTypeArguments()[0]);
}
My project was using Spring which is even better as Spring has a handy utility method for finding the type. This is the best approach for me as it looks neatest. I guess if you weren't using Spring you could write your own utility method.
import org.springframework.core.GenericTypeResolver;
public abstract class AbstractHibernateDao<T extends DomainObject> implements DataAccessObject<T>
{
@Autowired
private SessionFactory sessionFactory;
private final Class<T> genericType;
private final String RECORD_COUNT_HQL;
private final String FIND_ALL_HQL;
@SuppressWarnings("unchecked")
public AbstractHibernateDao()
{
this.genericType = (Class<T>) GenericTypeResolver.resolveTypeArgument(getClass(), AbstractHibernateDao.class);
this.RECORD_COUNT_HQL = "select count(*) from " + this.genericType.getName();
this.FIND_ALL_HQL = "from " + this.genericType.getName() + " t ";
}

Factory Method
(also called Factory
) is for decouple client of a Interface
implementation. For sample we have a Shape
interface with two Circle
and Square
implementations. We have define a factory class with a factory method with a determiner parameter such as Type
and new related implementation of Shape
interface.
Abstract Factory
contains several factory method or a factory interface by several factory implementations.
For next above sample we have a Color
interface with two Red
and Yellow
implementations.
We have define a ShapeColorFactory
interface with two RedCircleFactory
and YellowSquareFactory
. Following code for explain this concept:
interface ShapeColorFactory
{
public Shape getShape();
public Color getColor();
}
class RedCircleFactory implements ShapeColorFactory
{
@Override
public Shape getShape() {
return new Circle();
}
@Override
public Color getColor() {
return new Red();
}
}
class YellowSquareFactory implements ShapeColorFactory
{
@Override
public Shape getShape() {
return new Square();
}
@Override
public Color getColor() {
return new Yellow();
}
}
Here difference between FactoryMethod
and AbstractFactory
. Factory Method
as simply return a concrete class of a interface but Abstract Factory
return factory of factory
. In other words Abstract Factory
return different combine of a series of interface.
I hope my explanation useful.
For me the problem was with my activity_main.xml(21) in which the recycleView didn't have an id.
activity_main.xml(21)
<android.support.v7.widget.RecyclerView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/button3"
tools:listitem="@layout/transaction_list_row" />
activity_main.xml
<android.support.v7.widget.RecyclerView
android:id="@+id/transac_recycler_view"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/button3"
/>
It worked when i added a android:id="@+id/transac_recycler_view" to the activity_main.xml(21) recycleView
The problem is that omega
in your case is matrix
of dimensions 1 * 1
. You should convert it to a vector if you wish to multiply t(X) %*% X
by a scalar (that is omega
)
In particular, you'll have to replace this line:
omega = rgamma(1,a0,1) / L0
with:
omega = as.vector(rgamma(1,a0,1) / L0)
everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.)
or c(t(.))
. Both are equivalent.
Here's the modified code that should work:
gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1,
a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
m0 = c(m01, m02)
C0 = matrix(nrow = 2, ncol = 2)
C0[1,1] = 1 / k01
C0[1,2] = 0
C0[2,1] = 0
C0[2,2] = 1 / k02
beta = mvrnorm(1,m0,C0)
omega = as.vector(rgamma(1,a0,1) / L0)
draws = matrix(ncol = 3,nrow = ndraw)
it = -nburn
while (it < ndraw) {
it = it + 1
C1 = solve(solve(C0) + omega * t(X) %*% X)
m1 = C1 %*% (solve(C0) %*% m0 + omega * t(X) %*% y)
beta = mvrnorm(1, m1, C1)
a1 = a0 + n / 2
L1 = L0 + t(y - X %*% beta) %*% (y - X %*% beta) / 2
omega = as.vector(rgamma(1, a1, 1) / L1)
if (it > 0) {
draws[it,1] = beta[1]
draws[it,2] = beta[2]
draws[it,3] = omega
}
}
return(draws)
}
If we have a greater number of such svg images we can also take the help of font-files.
Sites like https://glyphter.com/ can get us a font file from our svgs.
E.g.
@font-face {
font-family: 'iconFont';
src: url('iconFont.eot');
}
#target{
color: white;
font-size:96px;
font-family:iconFont;
}
I managed to stop by adding those 2 lines

This is the best solution IMHO. It covers BOTH null
and empty
scenario, as is easy to understand when reading the code. All you need to know is that .getProperty
returns a null
when system prop is not set:
String DEFAULT_XYZ = System.getProperty("user.home") + "/xyz";
String PROP = Optional.ofNullable(System.getProperty("XYZ"))
.filter(s -> !s.isEmpty())
.orElse(DEFAULT_XYZ);
What's wrong with:
clob.getSubString(1, (int) clob.length());
?
For example Oracle oracle.sql.CLOB
performs getSubString()
on internal char[]
which defined in oracle.jdbc.driver.T4CConnection
and just System.arraycopy()
and next wrap to String
... You never get faster reading than System.arraycopy()
.
UPDATE Get driver ojdbc6.jar, decompile CLOB
implementation, and study which case could be faster based on the internals knowledge.
For your example, Dirk's answer is perfect. If you instead had a data frame and wanted to add that sort of sequence as a column, you could also use group
from groupdata2 (disclaimer: my package) to greedily divide the datapoints into groups.
# Attach groupdata2
library(groupdata2)
# Create a random data frame
df <- data.frame("x" = rnorm(27))
# Create groups with 5 members each (except last group)
group(df, n = 5, method = "greedy")
x .groups
<dbl> <fct>
1 0.891 1
2 -1.13 1
3 -0.500 1
4 -1.12 1
5 -0.0187 1
6 0.420 2
7 -0.449 2
8 0.365 2
9 0.526 2
10 0.466 2
# … with 17 more rows
There's a whole range of methods for creating this kind of grouping factor. E.g. by number of groups, a list of group sizes, or by having groups start when the value in some column differs from the value in the previous row (e.g. if a column is c("x","x","y","z","z")
the grouping factor would be c(1,1,2,3,3)
.
set text-decoration: none; for anchor tag.
Example html.
<body>
<ul class="nav-tabs">
<li><a href="#"><i class="fas fa-th"></i>Business</a></li>
<li><a href="#"><i class="fas fa-th"></i>Expertise</a></li>
<li><a href="#"><i class="fas fa-th"></i>Quality</a></li>
</ul>
</body>
Example CSS:
.nav-tabs li a{
text-decoration: none;
}
There are many ways for doing that (you might want to obfuscate the source code, you can compress it, ...). Some of these methods need additional code to transform your program in an executable form (compression, for example).
But the thing all methods cannot do, is keeping the source code secret. The other party gets your binary code, which can always be transformed (reverse-engineered) into a human-readable form again, because the binary code contains all functionality information that is provided in your source code.

If you want to send a custom HTTP Header (not a SOAP Header) then you need to use the HttpWebRequest class the code would look like:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("Authorization", token);
You cannot add HTTP headers using the visual studio generated proxy, which can be a real pain.
Oneliner:
obj = (function(attr, val){ var a = {}; a[attr]=val; return a; })('hash', 5);
Or:
attr = 'hash';
val = 5;
var obj = (obj={}, obj[attr]=val, obj);
Anything shorter?
in Jquery "data" doesn't refresh by default :
alert($('#outer').html());
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').data("myval","20"); //setter
alert($('#outer').html());
You'd use "attr" instead for live update:
alert($('#outer').html());
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').attr("data-myval","20"); //setter
alert($('#outer').html());
$('#message').val('');
Explanation (from @BalusC):
textarea
is an input
element with a value. You actually want to "empty" the value. So as for every other input
element (input
, select
, textarea
) you need to use element.val('');
.

Do not use the *
selector as that will apply to all elements on the page. Suppose you have a structure like this:
...
<body>
<div id="content">
<b>This is the main container.</b>
</div>
</body>
</html>
You can then center the #content
div using:
#content {
width: 400px;
margin: 0 auto;
background-color: #66ffff;
}
Don't know what you've seen elsewhere but this is the way to go. The * { margin: 0; padding: 0; }
snippet you've seen is for resetting browser's default definitions for all browsers to make your site behave similarly on all browsers, this has nothing to do with centering the main container.
Most browsers apply a default margin and padding to some elements which usually isn't consistent with other browsers' implementations. This is why it is often considered smart to use this kind of 'resetting'. The reset snippet you presented is the most simplest of reset stylesheets, you can read more about the subject here:

SQL Developer has a built-in reset password option that may work for your situation. It requires adding Oracle Instant Client to the workstation as well. When instant client is in the path when SQL developer launches you will get the following option enabled:
Oracle Instant Client does not need admin privileges to install, just the ability to write to a directory and add that directory to the users path. Most users have the privileges to do this.
Recap: In order to use Reset Password on Oracle SQL Developer:
At this point you can right click a data source and reset your password.

An alternative configuration to have SQL Developer (tested on version 4.0.1) recognize and use the Instant Client on OS X is:
(OS X) Refer to this question to resolve issues related to DYLD_LIBRARY_PATH environment variable. I used the following command and then restarted SQL Developer to pick up the change:
$ launchctl setenv DYLD_LIBRARY_PATH /path/to/oracle/instantclient_11_2
You can use MultiIndex.droplevel
:
>>> cols = pd.MultiIndex.from_tuples([("a", "b"), ("a", "c")])
>>> df = pd.DataFrame([[1,2], [3,4]], columns=cols)
>>> df
a
b c
0 1 2
1 3 4
[2 rows x 2 columns]
>>> df.columns = df.columns.droplevel()
>>> df
b c
0 1 2
1 3 4
[2 rows x 2 columns]

As you use Joda Time, you should use DateTimeFormatter
:
final DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
final LocalDate dt = dtf.parseLocalDate(yourinput);
If using Java 8 or later, then refer to hertzi's answer
The other answers will work for most strings, but you can end up unescaping an already escaped double quote, which is probably not what you want.
To work correctly, you are going to need to escape all backslashes and then escape all double quotes, like this:
var test_str = '"first \\" middle \\" last "';
var result = test_str.replace(/\\/g, '\\\\').replace(/\"/g, '\\"');
depending on how you need to use the string, and the other escaped charaters involved, this may still have some issues, but I think it will probably work in most cases.
I'm pretty sure C-style casting syntax works in Objective C, so try that, too:
int myInt = (int) myFloat;
It might silence a compiler warning, at least.
Since you're using GNUmake, use a pattern rule for compiling object files:
$(OBJDIR)/%.o: %.c
$(CC) $(CFLAGS) $(CPPFLAGS) -c -o $@ $<
I seem to have a blind spot as regards your html structure, but I think that this is what you're looking for. It should find the currently-selected option from the select
input, assign its text to the newVal
variable and then apply that variable to the value
attribute of the #costLabel
label:
$(document).ready(
function() {
$('select[name=package]').change(
function(){
var newText = $('option:selected',this).text();
$('#costLabel').text('Total price: ' + newText);
}
);
}
);
<form name="thisForm" id="thisForm" action="#" method="post">
<fieldset>
<select name="package" id="package">
<option value="standard">Standard - €55 Monthly</option>
<option value="standardAnn">Standard - €49 Monthly</option>
<option value="premium">Premium - €99 Monthly</option>
<option value="premiumAnn" selected="selected">Premium - €89 Monthly</option>
<option value="platinum">Platinum - €149 Monthly</option>
<option value="platinumAnn">Platinum - €134 Monthly</option>
</select>
</fieldset>
<fieldset>
<label id="costLabel" name="costLabel">Total price: </label>
</fieldset>
</form>
Working demo of the above at: JS Bin
Unfortunately, CSS does not provide 'inheritance' in the way that programming languages like C++, C# or Java do. You can't declare a CSS class an then extend it with another CSS class.
However, you can apply more than a single class to an tag in your markup ... in which case there is a sophisticated set of rules that determine which actual styles will get applied by the browser.
<span class="styleA styleB"> ... </span>
CSS will look for all the styles that can be applied based on what your markup, and combine the CSS styles from those multiple rules together.
Typically, the styles are merged, but when conflicts arise, the later declared style will generally win (unless the !important attribute is specified on one of the styles, in which case that wins). Also, styles applied directly to an HTML element take precedence over CSS class styles.
The LIKE
operator does not work with date parts like month or date but the DATEPART
operator does.
Command to find out all accounts whose Open Date was on the 1st:
SELECT *
FROM Account
WHERE DATEPART(DAY, CAST(OpenDt AS DATE)) = 1`
*CASTING OpenDt
because it's value is in DATETIME
and not just DATE
.
Am I missing something? Somebody correct me if I'm wrong.
list.RemoveAll(s => s.Name == "Fred");
You could also use this existing solution. The demo is here. It looks like youtube loading bar. I just found it and added it to my own project.
Give the DIV a specific with in percentage or pixels and center it using CSS margin property.
HTML
<div id="my-main-div"></div>
CSS
#my-main-div { margin: 0 auto; }

write to a temporary file which resides in RAM
it turns out the tempfile
module ( http://docs.python.org/library/tempfile.html ) has just the thing:
tempfile.SpooledTemporaryFile([max_size=0[, mode='w+b'[, bufsize=-1[, suffix=''[, prefix='tmp'[, dir=None]]]]]])
This function operates exactly as TemporaryFile() does, except that data is spooled in memory until the file size exceeds max_size, or until the file’s fileno() method is called, at which point the contents are written to disk and operation proceeds as with TemporaryFile().
The resulting file has one additional method, rollover(), which causes the file to roll over to an on-disk file regardless of its size.
The returned object is a file-like object whose _file attribute is either a StringIO object or a true file object, depending on whether rollover() has been called. This file-like object can be used in a with statement, just like a normal file.
New in version 2.6.
or if you're lazy and you have a tmpfs-mounted /tmp
on Linux, you can just make a file there, but you have to delete it yourself and deal with naming
If the aim is to just load the contents inside your application, you don't even need to use wget
:
$xmlData = file_get_contents('http://user:[email protected]/file.xml');
Note that this function will not work if allow_url_fopen
is disabled (it's enabled by default) inside either php.ini or the web server configuration (e.g. httpd.conf).
If your host explicitly disables it or if you're writing a library, it's advisable to either use cURL or a library that abstracts the functionality, such as Guzzle.
use GuzzleHttp\Client;
$client = new Client([
'base_url' => 'http://example.com',
'defaults' => [
'auth' => ['user', 'pass'],
]]);
$xmlData = $client->get('/file.xml');
It uses commas as separators. So you can either set sep=","
or just use read.csv
:
x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593 9
The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table
thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):
State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582
And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table
with the default quote
argument (but not read.csv
):
01,089,24,033,MD,Prince George's County,13,30,1040

to return your desired vector, then cbind
it to your matrix

The --net=host
option is used to make the programs inside the Docker container look like they are running on the host itself, from the perspective of the network. It allows the container greater network access than it can normally get.
Normally you have to forward ports from the host machine into a container, but when the containers share the host's network, any network activity happens directly on the host machine - just as it would if the program was running locally on the host instead of inside a container.
While this does mean you no longer have to expose ports and map them to container ports, it means you have to edit your Dockerfiles to adjust the ports each container listens on, to avoid conflicts as you can't have two containers operating on the same host port. However, the real reason for this option is for running apps that need network access that is difficult to forward through to a container at the port level.
For example, if you want to run a DHCP server then you need to be able to listen to broadcast traffic on the network, and extract the MAC address from the packet. This information is lost during the port forwarding process, so the only way to run a DHCP server inside Docker is to run the container as --net=host
.
Generally speaking, --net=host
is only needed when you are running programs with very specific, unusual network needs.
Lastly, from a security perspective, Docker containers can listen on many ports, even though they only advertise (expose) a single port. Normally this is fine as you only forward the single expected port, however if you use --net=host
then you'll get all the container's ports listening on the host, even those that aren't listed in the Dockerfile. This means you will need to check the container closely (especially if it's not yours, e.g. an official one provided by a software project) to make sure you don't inadvertently expose extra services on the machine.

When you
import App from './App.jsx';
That means it will import whatever you export default
. You can rename App
class inside App.jsx
to whatever you want as long as you export default
it will work but you can only have one export default.
So you only need to export default App
and you don't need to export the rest.
If you still want to export the rest of the components, you will need named export.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)
It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.
Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)
you will see a Words equivalent of the numeric value.

If you trust the data source, you can use eval
to convert your string into a dictionary:
eval(your_json_format_string)
Example:
>>> x = "{'a' : 1, 'b' : True, 'c' : 'C'}"
>>> y = eval(x)
>>> print x
{'a' : 1, 'b' : True, 'c' : 'C'}
>>> print y
{'a': 1, 'c': 'C', 'b': True}
>>> print type(x), type(y)
<type 'str'> <type 'dict'>
>>> print y['a'], type(y['a'])
1 <type 'int'>
>>> print y['a'], type(y['b'])
1 <type 'bool'>
>>> print y['a'], type(y['c'])
1 <type 'str'>

I just give other option for this question - you need to use '.dt' in your code:
import pandas as pd_x000D_
_x000D_
df.index = pd.to_datetime(df.index)_x000D_
_x000D_
#for get year_x000D_
df.index.dt.year_x000D_
_x000D_
#for get month_x000D_
df.index.dt.month_x000D_
_x000D_
#for get day_x000D_
df.index.dt.day_x000D_
_x000D_
#for get hour_x000D_
df.index.dt.hour_x000D_
_x000D_
#for get minute_x000D_
df.index.dt.minute
_x000D_
The simpler, the best:
img {
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto auto;
position: absolute;
}
Then you need to insert your img tag into a tag that sports position:relative property, as follows:
<div style="width:256px; height: 256px; position:relative;">
<img src="photo.jpg"/>
</div>

You can run your application with parameters such as app -something -somethingelse
. int argc
represents number of these parameters and char *argv[]
is an array with actual parameters being passed into your application. This way you can work with them inside of your application.
Use:
sed -n '1,100p' filename > output.txt
Here, 1 and 100 are the line numbers which you will capture in output.txt
