With new git difftool, its as simple as adding this to your .gitconfig file:
[diff]
tool = any-name
[difftool "any-name"]
cmd = "\"C:/path/to/my/ext/diff.exe\" \"$LOCAL\" \"$REMOTE\""
Optionally, also add:
[difftool]
prompt = false
Also check out diffall, a simple script I wrote to extend the annoying (IMO) default diff behaviour of opening each in serial.
Global .gitconfig on Windows is in %USERPROFILE%\.gitconfig
you can use the alias in this way on the delete statement
DELETE th.*
FROM term_hierarchy th
INNER JOIN term_hierarchy th2 ON (th1.tid = th2.tid AND th2.parent != 1015)
WHERE th.parent = 1015;
Using the mysqli PHP driver, you can't get the insert_id after you commit.
The real solution is this:
function add_post($post_data){
$this->db->trans_begin();
$this->db->insert('posts',$post_data);
$item_id = $this->db->insert_id();
if( $this->db->trans_status() === FALSE )
{
$this->db->trans_rollback();
return( 0 );
}
else
{
$this->db->trans_commit();
return( $item_id );
}
}

This will log true if character is uppercase letter, and log false in every other case:
var letters = ['a', 'b', 'c', 'A', 'B', 'C', '(', ')', '+', '-', '~', '*'];
???for (var ?i = 0; i<letters.length; i++) {
if (letters[i] === letters[i].toUpperCase()
&& letters[i] !== letters[i].toLowerCase()) {
console.log(letters[i] + ": " + true);
} else {
console.log(letters[i] + ": " + false);
}
}?
You may test it here: http://jsfiddle.net/Axfxz/ (use Firebug or sth).
???for (var ?i = 0; i<letters.length; i++) {
if (letters[i] !== letters[i].toUpperCase()
&& letters[i] === letters[i].toLowerCase()) {
console.log(letters[i] + ": " + true);
} else {
console.log(letters[i] + ": " + false);
}
}?
and this is for lowercase:).

Ran into a issue with the HTTPClient, even with the suggestions still could not get it to authenticate. Turns out I needed a trailing '/' in my relative path.
i.e.
var result = await _client.GetStringAsync(_awxUrl + "api/v2/inventories/?name=" + inventoryName);
var result = await _client.PostAsJsonAsync(_awxUrl + "api/v2/job_templates/" + templateId+"/launch/" , new {
inventory = inventoryId
});
I decided to use the json2 library and I got an error about “cyclic data structures”.
I got it solved by telling json2 how to convert my complex object. Not only it works now but also I have included only the fields I need. Here is how I did it:
OBJ.prototype.toJSON = function (key) {
var returnObj = new Object();
returnObj.devid = this.devid;
returnObj.name = this.name;
returnObj.speed = this.speed;
returnObj.status = this.status;
return returnObj;
}

There's nothing to be worried upon for this. Like other servers, install xampp somewhere outside of the default Program Files folder of Windows. It shall work fine.
I previously had wamp server installed on my machine and i never understood why wamp server installs itself outside of the default directory. Xampp cleared this, now i have both the servers lying outside the Program Files folder and are running fine.
The problem you're having is that the output you get into the variable 's' is not a csv, but a html file. In order to get the raw csv, you have to modify the url to:
'https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv'
Your second problem is that read_csv expects a file name, we can solve this by using StringIO from io module. Third problem is that request.get(url).content delivers a byte stream, we can solve this using the request.get(url).text instead.
End result is this code:
from io import StringIO
import pandas as pd
import requests
url='https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv'
s=requests.get(url).text
c=pd.read_csv(StringIO(s))
output:
>>> c.head()
Country Region
0 Algeria AFRICA
1 Angola AFRICA
2 Benin AFRICA
3 Botswana AFRICA
4 Burkina AFRICA
Another answer: There's a bookmarklet called ReCSS. I haven't used it extensively, but seems to work.
There's a bookmarklet on that page to drag and drop onto your address bar (Can't seem to make one here). In case that's broke, here's the code:
javascript:void(function()%7Bvar%20i,a,s;a=document.getElementsByTagName('link');for(i=0;i%3Ca.length;i++)%7Bs=a[i];if(s.rel.toLowerCase().indexOf('stylesheet')%3E=0&&s.href)%20%7Bvar%20h=s.href.replace(/(&%7C%5C?)forceReload=%5Cd%20/,'');s.href=h%20(h.indexOf('?')%3E=0?'&':'?')%20'forceReload='%20(new%20Date().valueOf())%7D%7D%7D)();
For a list, you could use a list comp. For example, to make b
a copy of a
without the 3rd element:
a = range(10)[::-1] # [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
b = [x for i,x in enumerate(a) if i!=3] # [9, 8, 7, 5, 4, 3, 2, 1, 0]
This is very general, and can be used with all iterables, including numpy arrays. If you replace []
with ()
, b
will be an iterator instead of a list.
Or you could do this in-place with pop
:
a = range(10)[::-1] # a = [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
a.pop(3) # a = [9, 8, 7, 5, 4, 3, 2, 1, 0]
In numpy you could do this with a boolean indexing:
a = np.arange(9, -1, -1) # a = array([9, 8, 7, 6, 5, 4, 3, 2, 1, 0])
b = a[np.arange(len(a))!=3] # b = array([9, 8, 7, 5, 4, 3, 2, 1, 0])
which will, in general, be much faster than the list comprehension listed above.
mylist[c(5,7,9)]
should do it.
You want the sublists returned as sublists of the result list; you don't use [[]]
(or rather, the function is [[
) for that -- as Dason mentions in comments, [[
grabs the element.
Here's a solution to your problem using dplyr's filter
function.
Although you can pass your data frame as the first argument to any dplyr function, I've used its %>%
operator, which pipes your data frame to one or more dplyr functions (just filter in this case).
Once you are somewhat familiar with dplyr, the cheat sheet is very handy.
> print(df <- data.frame(sub=rep(1:3, each=4), day=1:4))
sub day
1 1 1
2 1 2
3 1 3
4 1 4
5 2 1
6 2 2
7 2 3
8 2 4
9 3 1
10 3 2
11 3 3
12 3 4
> print(df <- df %>% filter(!((sub==1 & day==2) | (sub==3 & day==4))))
sub day
1 1 1
2 1 3
3 1 4
4 2 1
5 2 2
6 2 3
7 2 4
8 3 1
9 3 2
10 3 3
A few great suggestions are already mentioned. Using GSON is really handy indeed, and to make life even easier you can try this website It's called jsonschema2pojo and does exactly that:
You give it your json and it generates a java object that can paste in your project. You can select GSON to annotate your variables, so extracting the object from your json gets even easier!
The jsonify()
function in flask returns a flask.Response()
object that already has the appropriate content-type header 'application/json' for use with json responses. Whereas, the json.dumps()
method will just return an encoded string, which would require manually adding the MIME type header.
See more about the jsonify()
function here for full reference.
Edit:
Also, I've noticed that jsonify()
handles kwargs or dictionaries, while json.dumps()
additionally supports lists and others.
Wikipedia has this to say about the differences.
In general JScript is an ActiveX scripting language that is probably interpreted as JavaScript by non-IE browsers.
I found that these instructions were not enough. I also had to search through the code files for models, controllers, and views as well as the AppStart files to change the namespace.
Since I was copying my project not just renaming it, I also had to go into the applicationhost.config for IIS express and recreate the bindings using different port numbers and change the physical directory as well.
What I did is first check what are the running processes by
SELECT * FROM pg_stat_activity WHERE state = 'active';
Find the process you want to kill, then type:
SELECT pg_cancel_backend(<pid of the process>)
This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.
If the process cannot be killed, try:
SELECT pg_terminate_backend(<pid of the process>)
How about this:
SELECT MONTH('March' + ' 1 2014')
Would return 3
.
I found theDuncs answer very useful and below you can find my own (refactored) version:
- (void)viewWillAppear:(BOOL)animated {
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}
- (void)viewWillDisappear:(BOOL)animated {
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}
- (void)keyboardWillShow:(NSNotification *)notification {
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
float newVerticalPosition = -keyboardSize.height;
[self moveFrameToVerticalPosition:newVerticalPosition forDuration:0.3f];
}
- (void)keyboardWillHide:(NSNotification *)notification {
[self moveFrameToVerticalPosition:0.0f forDuration:0.3f];
}
- (void)moveFrameToVerticalPosition:(float)position forDuration:(float)duration {
CGRect frame = self.view.frame;
frame.origin.y = position;
[UIView animateWithDuration:duration animations:^{
self.view.frame = frame;
}];
}
Lodash can contribute a bug chunk of code to your bundle depending on how you import from it. For example:
// includes the entire package (very large)
import * as _ from 'lodash';
// depending on your buildchain, may still include the entire package
import { flatten } from 'lodash';
// imports only the code needed for `flatten`
import flatten from 'lodash-es/flatten'
Personally I still wanted smaller footprints from my utility functions. E.g. flatten
can contribute up to 1.2K
to your bundle, after minimization. So I've been building up a collection of simplified lodash functions. My implementation of flatten
contributes around 50 bytes
. You can check it out here to see if it works for you: https://github.com/simontonsoftware/micro-dash
I know this is really old, but I'm posting my solution anyways since google finds this thread.
background-image: url('./imagefolder/image.jpg');
That is what I do. Two dots means drill back one directory closer to root ".." while one "." should mean start where you are at as if it were root. I was having similar issues but adding that fixed it for me. You can even leave the "." in it when uploading to your host because it should work fine so long as your directory setup is exactly the same.
Faced with a similar problem sometime ago, I decided to go for a generalized "switch ... case ... break ... default" type solution together with an arm-style instruction set with conditional execution. A custom interpreter using a nesting stack was used to parse these "programs". This solution completely avoids id's or labels. All my XML language elements or "instructions" support a "condition" attribute which if not present or if it evaluates to true then the element's instruction is executed. If there is an "exit" attribute evaluating to true and the condition is also true, then the following group of elements/instructions at the same nesting level will neither be evaluated nor executed and the execution will continue with the next element/instruction at the parent level. If there is no "exit" or it evaluates to false, then the program will proceed with the next element/instruction. For example you can write this type of program (it will be useful to provide a noop "statement" and a mechanism/instruction to assign values and/or expressions to "variables" will prove very handy):
<ins-1>
<ins-11 condition="expr-a" exit="true">
<ins-111 />
...
</ins11>
<ins-12 condition="expr-b" exit="true" />
<ins-13 condition="expr-c" />
<ins-14>
...
</ins14>
</ins-1>
<ins-2>
...
</ins-2>
If expr-a is true then the execution sequence will be:
ins-1
ins-11
ins-111
ins-2
if expr-a is false and expr-b is true then it will be:
ins-1
ins-12
ins-2
If both expr-a and expr-b are false then we'll have:
ins-1
ins-13 (only if expr-c evaluates to true)
ins-14
ins-2
PS. I used "exit" instead of "break" because I used "break" to implement "breakpoints". Such programs are very hard to debug without some kind of breakpointing/tracing mechanism.
PS2. Because I had similar date-time conditions as your example along with the other types of conditions, I also implemented two special attributes: "from" and "until", that also had to evaluate to true if present, just like "condition", and which used special fast date-time checking logic.
I'm sure you have your reasons, but just in case... you should also consider using a "merge" query instead:
begin
merge into some_table st
using (select 'some' name, 'values' value from dual) v
on (st.name=v.name)
when matched then update set st.value=v.value
when not matched then insert (name, value) values (v.name, v.value);
end;
(modified the above to be in the begin/end block; obviously you can run it independantly of the procedure too).

You just missed an initialization step I think.
You can see what fonts you have available with the command windowsFonts()
. For example mine looks like this when I started looking at this:
> windowsFonts()
$serif
[1] "TT Times New Roman"
$sans
[1] "TT Arial"
$mono
[1] "TT Courier New"
After intalling the package extraFont and running font_import
like this (it took like 5 minutes):
library(extrafont)
font_import()
loadfonts(device = "win")
I had many more available - arguable too many, certainly too many to list here.
Then I tried your code:
library(ggplot2)
library(extrafont)
loadfonts(device = "win")
a <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
ggtitle("Fuel Efficiency of 32 Cars") +
xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
theme(text=element_text(size=16, family="Comic Sans MS"))
print(a)
yielding this:
You can find the name of a font you need for the family
parameter of element_text
with the following code snippet:
> names(wf[wf=="TT Times New Roman"])
[1] "serif"
And then:
library(ggplot2)
library(extrafont)
loadfonts(device = "win")
a <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
ggtitle("Fuel Efficiency of 32 Cars") +
xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
theme(text=element_text(size=16, family="serif"))
print(a)
As per the manual you can often install a custom php.ini on shared hosting, where mod_php isn't used and the php_value
directive thus leads to an error. For suexec/FastCGI setups it is quite common to have a per-webspace php.ini
in any case.
--
I don't think O (uppercase letter o) is a valid value to set an ini flag. You need to use a true/false, 1/0, or "on"/"off" value.
ini_set( 'magic_quotes_gpc', 0 ); // doesn't work
EDIT
After checking the list of ini settings, I see that magic_quotes_gpc is a PHP_INI_PERDIR
setting (after 4.2.3), which means you can't change it with ini_set()
(only PHP_INI_ALL
settings can be changed with ini_set()
)
What this means is you have to use an .htaccess file to do this - OR - implement a script to reverse the effects of magic quotes. Something like this
if ( in_array( strtolower( ini_get( 'magic_quotes_gpc' ) ), array( '1', 'on' ) ) )
{
$_POST = array_map( 'stripslashes', $_POST );
$_GET = array_map( 'stripslashes', $_GET );
$_COOKIE = array_map( 'stripslashes', $_COOKIE );
}
Try this
$('#thisElement .classToSelect').each(function(i){
// do stuff
});
Hope it will help
Open phpMyAdmin and select the SQL tab. Then type this command:
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('your_root_password');
Also change to this line in config.inc.php
:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
To make phpMyAdmin prompts for your MySQL username and password.

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.
More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:
ping -s 1472
...)tc
iperf
Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat
or lsof
). If that number is substantial, you might:
ulimit -n
. Still, ~1000 connections (default on my system) is quite a few.iostat -x
?Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.
I hope this provides some help. You're really asking a networking question.
In this example, nothing really. The exact
param comes into play when you have multiple paths that have similar names:
For example, imagine we had a Users
component that displayed a list of users. We also have a CreateUser
component that is used to create users. The url for CreateUsers
should be nested under Users
. So our setup could look something like this:
<Switch>
<Route path="/users" component={Users} />
<Route path="/users/create" component={CreateUser} />
</Switch>
Now the problem here, when we go to http://app.com/users
the router will go through all of our defined routes and return the FIRST match it finds. So in this case, it would find the Users
route first and then return it. All good.
But, if we went to http://app.com/users/create
, it would again go through all of our defined routes and return the FIRST match it finds. React router does partial matching, so /users
partially matches /users/create
, so it would incorrectly return the Users
route again!
The exact
param disables the partial matching for a route and makes sure that it only returns the route if the path is an EXACT match to the current url.
So in this case, we should add exact
to our Users
route so that it will only match on /users
:
<Switch>
<Route exact path="/users" component={Users} />

Those list comprehensions are messy after a while.
from operator import itemgetter
def collect(l, index):
return map(itemgetter(index), l)
# And now you can write this:
collect(tuple_list,0).index("cherry") # = 1
collect(tuple_list,1).index("3") # = 2
# Stops iterating through the list as soon as it finds the value
def getIndexOfTuple(l, index, value):
for pos,t in enumerate(l):
if t[index] == value:
return pos
# Matches behavior of list.index
raise ValueError("list.index(x): x not in list")
getIndexOfTuple(tuple_list, 0, "cherry") # = 1
Hope this will help somebody to develop custom checkbox component with custom styles. This solution can use with forms too.

Do you want to know if a type is the same type as int64_t or do you want to know if something is 64 bits? Based on your proposed solution, I think you're asking about the latter. In that case, I would do something like
template<typename T>
bool is_64bits() { return sizeof(T) * CHAR_BIT == 64; } // or >= 64
I knew how to use threads before I knew .NET, so it took some getting used to when I began using BackgroundWorker
s. Matt Davis has summarized the difference with great excellence, but I would add that it's more difficult to comprehend exactly what the code is doing, and this can make debugging harder. It's easier to think about creating and shutting down threads, IMO, than it is to think about giving work to a pool of threads.
I still can't comment other people's posts, so forgive my momentary lameness in using an answer to address piers7
Don't use Thread.Abort();
instead, signal an event and design your thread to end gracefully when signaled. Thread.Abort()
raises a ThreadAbortException
at an arbitrary point in the thread's execution, which can do all kinds of unhappy things like orphan Monitors, corrupt shared state, and so on.

Your task declaration is incorrectly combining the Copy
task type and project.copy
method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy
isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File
API) will do. Assuming Project1
is the project directory:
task renABCToXYZ { doLast { file("ABC").renameTo(file("XYZ")) } }
Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast
task action) to the task that produces ABC
.
Just to add another example:
I was replacing src attr in img html tags, but i needed to replace only the src and keep any text between the img declaration and src attribute.
Nathan's answer will give you jokes from last 24, 168, and 744 hours, NOT the jokes from today, this week, this month. If that's what you want, great, but I think you might be looking for something different.
Using his code, at noon, you will get the jokes beginning yesterday at noon, and ending today at noon. If you really want today's jokes, try the following:
SELECT * FROM jokes WHERE date >= CURRENT_DATE() ORDER BY score DESC;
You would have to do something a little different from current week, month, etc., but you get the idea.
Do you want the files to save as UTF-8 because you are using special characters that would be lost in ASCII encoding? If that's the case, then there is a VS2008 global setting in Tools > Options > Environment > Documents
, named Save documents as Unicode when data cannot be saved in codepage
. When this is enabled, VS2008 will save as Unicode if certain characters cannot be represented in the otherwise-default codepage.
Also, which files are not being saved as UTF-8? All of my .cs, .csproj, .sln, .config, .as*x, etc, all save as UTF-8 (with signature, the byte order marks), by default.

I had the same problem on my eclipse, and calling eclipse -clean did not solve the problem.
In the end I figured out that within the installation folder of eclipse there is a script called eclipse. This script does some setting of environment variables and then calls eclipse.bin. The call for eclipse.bin contained the command line switch
-data ~/.eclipse
When I removed that switch from start-up script, I got the workspace selection as expected. Maybe that helps others to solve their problems.
If you're using VSCode:
1.
cmd + ,
)jshint.options
into the search bar"esversion": 6
to the options object.2.
Or simply add this to your user settings:
"jshint.options": {
"esversion": 6
}
[UPDATE] new vscode settings
cmd + ,
)jshint
into search2.
The best way to use is white-space: nowrap;
This will align the text to one line.
My approach. Tricky, but works well for me

Each tablespace has one or more datafiles that it uses to store data.
The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.
To find out if the actual limit is 32gb, run the following:
select value from v$parameter where name = 'db_block_size';
Compare the result you get with the first column below, and that will indicate what your max datafile size is.
I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).
Block Sz Max Datafile Sz (Gb) Max DB Sz (Tb)
-------- -------------------- --------------
2,048 8,192 524,264
4,096 16,384 1,048,528
8,192 32,768 2,097,056
16,384 65,536 4,194,112
32,768 131,072 8,388,224
You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):
select bytes/1024/1024 as mb_size,
maxbytes/1024/1024 as maxsize_set,
x.*
from dba_data_files x
MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).
If your datafile has a low max size or autoextend is not on you could simply run:
alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;
However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:
alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;
You can use the built-in pathlib
module (requires Python 3.4+, but there are backports for older versions on PyPI: pathlib
, pathlib2
).
To remove a file there is the unlink
method:
import pathlib
path = pathlib.Path(name_of_file)
path.unlink()
Or the rmdir
method to remove an empty folder:
import pathlib
path = pathlib.Path(name_of_folder)
path.rmdir()
try this one is a very easy method if you are in list of model foreach (var item in Modal) loop
<th:href="/category/edit/@item.idCategory>View</a>"
or
<th:href="/category/edit/@item.idCategory">View</a>
I had to change my password to the latest in the user.home/.m2/settings.xml file!
Another easy way to do this is to place your UIImageView
within a UIScrollView
. As I describe here, you need to set the scroll view's contentSize to be the same as your UIImageView's
size. Set your controller instance to be the delegate of the scroll view and implement the viewForZoomingInScrollView:
and scrollViewDidEndZooming:withView:atScale:
methods to allow for pinch-zooming and image panning. This is effectively what Ben's solution does, only in a slightly more lightweight manner, as you don't have the overhead of a full web view.
One issue you may run into is that the scaling within the scroll view comes in the form of transforms applied to the image. This may lead to blurriness at high zoom factors. For something that can be redrawn, you can follow my suggestions here to provide a crisper display after the pinch gesture is finished. hniels' solution could be used at that point to rescale your image.
I think your compiled coffee script is missing from the published npm package. Try writing a prepublish command.
There is also a PECL extension for xdiff:
In particular:
Example from PHP Manual:
<?php
$old_article = file_get_contents('./old_article.txt');
$new_article = $_POST['article'];
$diff = xdiff_string_diff($old_article, $new_article, 1);
if (is_string($diff)) {
echo "Differences between two articles:\n";
echo $diff;
}

Render method does not necessarily have to return a single element. An array can also be returned.
var indents = [];
for (var i = 0; i < this.props.level; i++) {
indents.push(<span className='indent' key={i}></span>);
}
return indents;
OR
return this.props.level.map((item, index) => (
<span className="indent" key={index}>
{index}
</span>
));
Docs here explaining about JSX children
OLD:
You can use one loop instead
var indents = [];
for (var i = 0; i < this.props.level; i++) {
indents.push(<span className='indent' key={i}></span>);
}
return (
<div>
{indents}
"Some text value"
</div>
);
You can also use .map and fancy es6
return (
<div>
{this.props.level.map((item, index) => (
<span className='indent' key={index} />
))}
"Some text value"
</div>
);
Also, you have to wrap the return value in a container. I used div in the above example
As the docs say here
Currently, in a component's render, you can only return one node; if you have, say, a list of divs to return, you must wrap your components within a div, span or any other component.
Please use json.Decoder
instead of json.Unmarshal
.
func test(rw http.ResponseWriter, req *http.Request) {
decoder := json.NewDecoder(req.Body)
var t test_struct
err := decoder.Decode(&t)
if err != nil {
panic(err)
}
log.Println(t.Test)
}
I had exactly the same error. My network is an internal one of a company. I downloaded neon-eclipse for java developpers. These steps worked for me:
1- I downloaded a VPN client on my PC to be totally blinded from the network. Shellfire I used. Use free account and connect to Shellserver.
2- Inside the windows firewall, I added incoming rule for Eclipse. Navigate to where eclipse exe is found.
3- Perform Maven Update project.
Then the project was able to fetch from the maven repository.
hope it helps.
First, remove all explicit setting of modal presentation style in code and do the following:

They seem to be working even unchecked.These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default.
But if you have to send non-ASCII text or large binary data, the form-data is for that.
You can use Raw if you want to send plain text or JSON or any other kind of string. Like the name suggests, Postman sends your raw string data as it is without modifications. The type of data that you are sending can be set by using the content-type header from the drop down.
Binary can be used when you want to attach non-textual data to the request, e.g. a video/audio file, images, or any other binary data file.
Refer to this link for further reading: Forms in HTML documents
First off, you shouldn't add $
when you're outside of strings ($class
in your first function being an exception), so it should be:
def doCopyMibArtefactsHere(projectName) {
step ([
$class: 'CopyArtifact',
projectName: projectName,
filter: '**/**.mib',
fingerprintArtifacts: true,
flatten: true
]);
}
def BuildAndCopyMibsHere(projectName, params) {
build job: project, parameters: params
doCopyMibArtefactsHere(projectName)
}
...
Now, as for your problem; the second function takes two arguments while you're only supplying one argument at the call. Either you have to supply two arguments at the call:
...
node {
stage('Prepare Mib'){
BuildAndCopyMibsHere('project1', null)
}
}
... or you need to add a default value to the functions' second argument:
def BuildAndCopyMibsHere(projectName, params = null) {
build job: project, parameters: params
doCopyMibArtefactsHere($projectName)
}
check if if your artifact Y have packaging set to "jar". If you have defined it as "war" by error or copy paste, it will show this strange "was cached in the local repository, resolution will not be reattempted until the update interval of internal has elapsed or updates are forced". I would expect something like "artifact Y is war, jar type expected".
Either use a div with square dimensions with the image inside with the .testimg class:
.test {
width: 307px;
height: 307px;
overflow:hidden
}
.testimg {
margin-left: -76px
}
or a square div with a background of the image.
.test2 {
width: 307px;
height: 307px;
background: url(http://i.stack.imgur.com/GA6bB.png) 50% 50%
}

HTTP_HOST and REQUEST_URI must be in quotes, otherwise it throws an error in PHP 7.2
Use:
$actual_link = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
If you want to support both HTTP and HTTPS:
$actual_link = (isset($_SERVER['HTTPS']) ? 'https' : 'http').'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
As RocketDonkey suggested, your module itself needs to have some docstrings.
For example, in myModule/__init__.py
:
"""
The mod module
"""
You'd also want to generate documentation for each file in myModule/*.py
using
pydoc myModule.thefilename
to make sure the generated files match the ones that are referenced from the main module documentation file.
Just Use like that
Response.Clear();
Response.ContentType = "application/CSV";
Response.AddHeader("content-disposition", "attachment; filename=\"" + filename + ".csv\"");
Response.Write(t.ToString());
Response.End();
Using wget
wget -O /tmp/myfile 'http://www.google.com/logo.jpg'

@DanielVelkov answer is the proper one BUT using string literals is faster:
# Daniel's
%timeit df.apply(lambda x:'%s is %s' % (x['bar'],x['foo']),axis=1)
## 963 µs ± 157 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
# String literals - python 3
%timeit df.apply(lambda x: f"{x['bar']} is {x['foo']}", axis=1)
## 849 µs ± 4.28 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
Given a predefined m-by-n
matrix size and the target value val
, in your example:
m = 1;
n = 10;
val = 5;
there are currently 7
different approaches that come to my mind:
1) Using the repmat function (0.094066 seconds)
A = repmat(val,m,n)
2) Indexing on the undefined matrix with assignment (0.091561 seconds)
A(1:m,1:n) = val
3) Indexing on the target value using the ones function (0.151357 seconds)
A = val(ones(m,n))
4) Default initialization with full assignment (0.104292 seconds)
A = zeros(m,n);
A(:) = val
5) Using the ones function with multiplication (0.069601 seconds)
A = ones(m,n) * val
6) Using the zeros function with addition (0.057883 seconds)
A = zeros(m,n) + val
7) Using the repelem function (0.168396 seconds)
A = repelem(val,m,n)
After the description of each approach, between parentheses, its corresponding benchmark performed under Matlab 2017a
and with 100000
iterations. The winner is the 6th
approach, and this doesn't surprise me.
The explaination is simple: allocation generally produces zero-filled slots of memory... hence no other operations are performed except the addition of val
to every member of the matrix, and on the top of that, input arguments sanitization is very short.
The same cannot be said for the 5th
approach, which is the second fastest one because, despite the input arguments sanitization process being basically the same, on memory side three operations are being performed instead of two:

On Windows 10 with Vagrant 2.2.2, setting the environment variable VAGRANT_HOME
will ensure that boxes are downloaded to a subfolder of the folder specified for VAGRANT_HOME
.
In my case I set VAGRANT_HOME
to e:\vagrant_home
, and the boxes get stored under e:\vagrant_home\boxes
.
This works for me.
That's where the boxes are stored. The virtual machines are being created in the folder configured in Virtual Box. To set the VirtualBox VM storage folder, go to: VirtualBox GUI --> File --> Preferences --> General --> Default Machine Folder
.
Change Column Name/Type/Position/Comment:
ALTER TABLE table_name CHANGE [COLUMN] col_old_name col_new_name column_type [COMMENT col_comment] [FIRST|AFTER column_name]
Example:
CREATE TABLE test_change (a int, b int, c int);
// will change column a's name to a1
ALTER TABLE test_change CHANGE a a1 INT;
Change that import to
from matplotlib.pyplot import *
Note that this style of imports (from X import *
) is generally discouraged. I would recommend using the following instead:
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

I haven't worked much with Appcelerator Titanium, but I'll put my understanding of it at the end.
I can speak a bit more to the differences between PhoneGap and Xamarin, as I work with these two 5 (or more) days a week.
If you are already familiar with C# and JavaScript, then the question I guess is, does the business logic lie in an area more suited to JavaScript or C#?
PhoneGap is designed to allow you to write your applications using JavaScript and HTML, and much of the functionality that they do provide is designed to mimic the current proposed specifications for the functionality that will eventually be available with HTML5. The big benefit of PhoneGap in my opinion is that since you are doing the UI with HTML, it can easily be ported between platforms. The downside is, because you are porting the same UI between platforms, it won't feel quite as at home in any of them. Meaning that, without further tweaking, you can't have an application that feels fully at home in iOS and Android, meaning that it has the iOS and Android styling. The majority of your logic can be written using JavaScript, which means it too can be ported between platforms. If the current PhoneGap API does most of what you want, then it's pretty easy to get up and running. If however, there are things you need from the device that are not in the API, then you get into the fun of Plugin Development, which will be in the native device's development language of choice (with one caveat, but I'll get to that), which means you would likely need to get up to speed quickly in Objective-C, Java, etc. The good thing about this model, is you can usually adapt many different native libraries to serve your purpose, and many libraries already have PhoneGap Plugins. Although you might not have much experience with these languages, there will at least be a plethora of examples to work from.
Xamarin.iOS and Xamarin.Android (also known as MonoTouch and MonoDroid), are designed to allow you to have one library of business logic, and use this within your application, and hook it into your UI. Because it's based on .NET 4.5, you get some awesome lambda notations, LINQ, and a whole bunch of other C# awesomeness, which can make writing your business logic less painful. The downside here is that Xamarin expects that you want to make your applications truly feel native on the device, which means that you will likely end up rewriting your UI for each platform, before hooking it together with the business logic. I have heard about MvvmCross, which is designed to make this easier for you, but I haven't really had an opportunity to look into it yet. If you are familiar with the MVVM system in C#, you may want to have a look at this. When it comes to native libraries, MonoTouch becomes interesting. MonoTouch requires a Binding library to tell your C# code how to link into the underlying Objective-C and Java code. Some of these libraries will already have bindings, but if yours doesn't, creating one can be, interesting. Xamarin has made a tool called Objective Sharpie to help with this process, and for the most part, it will get you 95% of the way there. The remaining 5% will probably take 80% of your time attempting to bind a library.
Update
As noted in the comments below, Xamarin has released Xamarin Forms which is a cross platform abstraction around the platform specific UI components. Definitely worth the look.
Now because I said I would get to it, the caveat mentioned in PhoneGap above, is a Hybrid approach, where you can use PhoneGap for part, and Xamarin for part. I have quite a bit of experience with this, and I would caution you against it. Highly. The problem with this, is it is such a no mans' land that if you ever run into issues, almost no one will have come close to what you're doing, and will question what you're trying to do greatly. It is doable, but it's definitely not fun.
As I mentioned before, I haven't worked much with Appcelerator Titanium, So for the differences between them, I will suggest you look at Comparing Titanium and Phonegap or Comparison between Corona, Phonegap, Titanium as it has a very thorough description of the differences. Basically, it appears that though they both use JavaScript, how that JavaScript is interpreted is slightly different. With Titanium, you will be writing your JavaScript to the Titanium SDK, whereas with PhoneGap, you will write your application using the PhoneGap API. As PhoneGap is very HTML5 and JavaScript standards compliant, you can use pretty much any JavaScript libraries you want, such as JQuery. With PhoneGap your user interface will be composed of HTML and CSS. With Titanium, you will benefit from their Cross-platform XML which appears to generate Native components. This means it will definitely have a better native look and feel.
I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).
A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.
Do like this:
create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;
Increasing Java Heap unfairly eats deficit mobile resurces. Sometimes it is sufficient to just wait for garbage collector and then resume your operations after heap space is reduced. Use this static method then.
"assert" statements are removed when the compilation is optimized. So, yes, there are both performance and functional differences.
The current code generator emits no code for an assert statement when optimization is requested at compile time. - Python 2 Docs Python 3 Docs
If you use assert
to implement application functionality, then optimize the deployment to production, you will be plagued by "but-it-works-in-dev" defects.

On the Unity Editor open your project and:
If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:
cd to/your/unity/project/folder
git init
git add *
git commit -m "First commit"
git remote add origin [email protected]:username/project.git
git push -u origin master
You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).
Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.
And here's my own .gitignore recipe for my Unity projects:

clearfix
should contain the floating elements but in your html you have added clearfix
only after floating right that is your pull-right
so you should do like this:
<div class="clearfix">
<div id="sidebar">
<ul>
<li>A</li>
<li>A</li>
<li>C</li>
<li>D</li>
<li>E</li>
<li>F</li>
<li>...</li>
<li>Z</li>
</ul>
</div>
<div id="main">
<div>
<div class="pull-right">
<a>RIGHT</a>
</div>
</div>
<div>MOVED BELOW Z</div>
</div>
Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden;
as you have done in your main.
Often, you don't need any auto*
tools and the simplest solution is to simply run touch aclocal.m4 configure
in the relevant folder (and also run touch
on Makefile.am
and Makefile.in
if they exist). This will update the timestamp of aclocal.m4
and remind the system that aclocal.m4
is up-to-date and doesn't need to be rebuilt. After this, it's probably best to empty your build
directory and rerun configure
from scratch after doing this. I run into this problem regularly. For me, the root cause is that I copy a library (e.g. mpfr
code for gcc
) from another folder and the timestamps change.
Of course, this trick isn't valid if you really do need to regenerate those files, perhaps because you have manually changed them. But hopefully the developers of the package distribute up-to-date files.
And of course, if you do want to install automake
and friends, then use the appropriate package-manager for your distribution.
Install aclocal which comes with automake:
brew install automake # for Mac
apt-get install automake # for Ubuntu
Try again:
./configure && make
1st solution (fastest) :
yourDateTime.Year % 100
2nd solution (more elegant in my opinion) :
yourDateTime.ToString("yy")
DHT nodes have unique identifiers, termed, Node ID. Node IDs are chosen at random from the same 160-bit space as BitTorrent info-hashes. Closeness is measured by comparing Node ID's routing tables, the closer the Node, the more detailed, resulting in optimal
What then makes them more optimal than it's predecessor "Kademlia" which used simple unsigned integers: distance(A,B) = |A xor B| Smaller values are closer. XOR. Besides not being secure, its logic was flawed.
If your client supports DHT, there are 8-bytes reserved in which contains 0x09 followed by a 2-byte payload with the UDP Port and DHT node. If the handshake is successful the above will continue.
Change this:
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>Content-Type, Last-Modified</param-value>
</init-param>
To this
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>Accept, Origin, X-Requested-With, Content-Type, Last-Modified</param-value>
</init-param>
I had to do this to get anything to work.
I had the same problem and can't get a good tip for this over the web, so I shared this for you and for all who needs.
In my situation I copy a database (all files: frm, myd) to the data folder in MySQL data folder (using Wamp at home). All thing was OK until I want to create a table and have the error #1146 Table '...' doesn't exist!
.
I use Wamp 2.1 with MySQL version 5.5.16.
My solution:
Export the database to file;
verify if exported file is really OK!!;
drop the database where I have issues;
create a new database with the same name that the last;
import the file to the database.
FOR ME IS PROBLEM SOLVED. Now I can create tables again without errors.

Thanks to everyone's contributions to this question, I've come up with the following script. Change the values for $SvcName
and $SvrName
to suit your needs. This script will start the remote service if it is stopped, or stop it if it is started. And it uses the cool .WaitForStatus
method to wait while the service responds.
#Change this values to suit your needs:
$SvcName = 'Spooler'
$SvrName = 'remotePC'
#Initialize variables:
[string]$WaitForIt = ""
[string]$Verb = ""
[string]$Result = "FAILED"
$svc = (get-service -computername $SvrName -name $SvcName)
Write-host "$SvcName on $SvrName is $($svc.status)"
Switch ($svc.status) {
'Stopped' {
Write-host "Starting $SvcName..."
$Verb = "start"
$WaitForIt = 'Running'
$svc.Start()}
'Running' {
Write-host "Stopping $SvcName..."
$Verb = "stop"
$WaitForIt = 'Stopped'
$svc.Stop()}
Default {
Write-host "$SvcName is $($svc.status). Taking no action."}
}
if ($WaitForIt -ne "") {
Try { # For some reason, we cannot use -ErrorAction after the next statement:
$svc.WaitForStatus($WaitForIt,'00:02:00')
} Catch {
Write-host "After waiting for 2 minutes, $SvcName failed to $Verb."
}
$svc = (get-service -computername $SvrName -name $SvcName)
if ($svc.status -eq $WaitForIt) {$Result = 'SUCCESS'}
Write-host "$Result`: $SvcName on $SvrName is $($svc.status)"
}
Of course, the account you run this under will need the proper privileges to access the remote computer and start and stop services. And when executing this against older remote machines, you might first have to install WinRM 3.0 on the older machine.

For checking Java version in android studio version , simply open Terminal of Android Studio and type

This will display java version installed in android studio
I know an answer has already been accepted, but wanted to point a few things out.
Setting the content-type
and charset
is obviously a good practice, doing it on the server is much better, because it ensures consistency across your application.
However, I would use UTF-8
only when the language of my application uses a lot of characters that are available only in the UTF-8
charset. If you want to show a unicode character or symbol in one of cases, you can do so without changing the charset
of your page.
HTML
renderers have always been able to display symbols which are not part of the encoding character set of the page, as long as you mention the symbol in its numeric character reference (NCR)
. Sounds weird but its true.
So, even if your html
has a header that states it has an encoding of ansi
or any of the iso
charsets, you can display a check mark by using its html character reference, in decimal - ✓ or in hex - ✓
So its a little difficult to understand why you are facing this issue on your pages. Can you check if the NCR value is correct, this is a good reference http://www.fileformat.info/info/unicode/char/2713/index.htm
Try setting the parameters' "default value" to use the same query as the "available values". In effect it provides every single "available value" as a "default value" and the "Select All" option is automatically checked.
I also had the same problem, I searched for the answers many places. I got many similar answers to change the number of process/service handlers. But I thought, what if I forgot to reset it back?
Then I tried using Thread.sleep()
method after each of my connection.close();
.
I don't know how, but it's working at least for me.
If any one wants to try it out and figure out how it's working then please go ahead. I would also like to know it as I am a beginner in programming world.
try this code
using hidden field we can pass php varibale to another page
page1.php
<?php $myVariable = "Some text";?>
<form method="post" action="page2.php">
<input type="hidden" name="text" value="<?php echo $myVariable; ?>">
<button type="submit">Submit</button>
</form>
pass php variable to hidden field value so you can access this variable into another page
page2.php
<?php
$text=$_POST['text'];
echo $text;
?>
JSON.stringify(data).length return string length not Object length, you can use Object.keys.
<% for(var i=0; i < Object.keys(data).length ; i++) {%>
If you set
android:inputType="textPassword"
this property and if you provide number as password example "1234567" it will take it as "123456/" the seventh character is not taken. Thats why instead of this approach use
android:password="true"
property which allows you to enter any type of password without any restriction.
If you want to provide hint use
android:hint="hint text goes here"
example:
android:hint="password"
Try Character.getNumericValue(char)
.
String element = "el5";
int x = Character.getNumericValue(element.charAt(2));
System.out.println("x=" + x);
produces:
x=5
The nice thing about getNumericValue(char)
is that it also works with strings like "el?"
and "el?"
where ?
and ?
are the digits 5 in Eastern Arabic and Hindi/Sanskrit respectively.
The best answer is...
The expression in the accepted answer misses many cases. Among other things, URLs can have unicode characters in them. The regex you want is here, and after looking at it, you may conclude that you don't really want it after all. The most correct version is ten-thousand characters long.
Admittedly, if you were starting with plain, unstructured text with a bunch of URLs in it, then you might need that ten-thousand-character-long regex. But if your input is structured, use the structure. Your stated aim is to "extract the url, inside the anchor tag's href." Why use a ten-thousand-character-long regex when you can do something much simpler?
For many tasks, using Beautiful Soup will be far faster and easier to use:
>>> from bs4 import BeautifulSoup as Soup
>>> html = Soup(s, 'html.parser') # Soup(s, 'lxml') if lxml is installed
>>> [a['href'] for a in html.find_all('a')]
['http://example.com', 'http://example2.com']
If you prefer not to use external tools, you can also directly use Python's own built-in HTML parsing library. Here's a really simple subclass of HTMLParser
that does exactly what you want:
from html.parser import HTMLParser
class MyParser(HTMLParser):
def __init__(self, output_list=None):
HTMLParser.__init__(self)
if output_list is None:
self.output_list = []
else:
self.output_list = output_list
def handle_starttag(self, tag, attrs):
if tag == 'a':
self.output_list.append(dict(attrs).get('href'))
Test:
>>> p = MyParser()
>>> p.feed(s)
>>> p.output_list
['http://example.com', 'http://example2.com']
You could even create a new method that accepts a string, calls feed
, and returns output_list
. This is a vastly more powerful and extensible way than regular expressions to extract information from html.
The tr
command could be replaced by //
bashism:
COMMAND=$'\nREBOOT\r \n'
echo "|${COMMAND}|"
|
OOT
|
echo "|${COMMAND//[$'\t\r\n']}|"
|REBOOT |
echo "|${COMMAND//[$'\t\r\n ']}|"
|REBOOT|
See Parameter Expansion and QUOTING in bash's man page:
man -Pless\ +/\/pattern bash
man -Pless\ +/\\\'string\\\' bash
man -Pless\ +/^\\\ *Parameter\\\ Exp bash
man -Pless\ +/^\\\ *QUOTING bash
As asked by @AlexJordan, this will suppress all specified characters. So what if $COMMAND
do contain spaces...
COMMAND=$' \n RE BOOT \r \n'
echo "|$COMMAND|"
|
BOOT
|
CLEANED=${COMMAND//[$'\t\r\n']}
echo "|$CLEANED|"
| RE BOOT |
shopt -q extglob || { echo "Set shell option 'extglob' on.";shopt -s extglob;}
CLEANED=${CLEANED%%*( )}
echo "|$CLEANED|"
| RE BOOT|
CLEANED=${CLEANED##*( )}
echo "|$CLEANED|"
|RE BOOT|
Shortly:
COMMAND=$' \n RE BOOT \r \n'
CLEANED=${COMMAND//[$'\t\r\n']} && CLEANED=${CLEANED%%*( )}
echo "|${CLEANED##*( )}|"
|RE BOOT|
Note: bash have extglob
option to be enabled (shopt -s extglob
) in order to use *(...)
syntax.
Update: I added a fix for the OP's comment.
tar -czf workspace.tar.gz .
will indeed change the current directory, but why not place the file somewhere else?
tar -czf somewhereelse/workspace.tar.gz .
mv somewhereelse/workspace.tar.gz . # Update
Change this.foo()
to module.exports.foo()
You can use the stream api and a StringReader wrapped in a BufferedReader which got a lines() stream output in java 8:
import java.util.stream.*;
import java.io.*;
class test {
public static void main(String... a) {
String s = "this is a \nmultiline\rstring\r\nusing different newline styles";
new BufferedReader(new StringReader(s)).lines().forEach(
(line) -> System.out.println("one line of the string: " + line)
);
}
}
Gives
one line of the string: this is a
one line of the string: multiline
one line of the string: string
one line of the string: using different newline styles
Just like in BufferedReader's readLine, the newline character(s) themselves are not included. All kinds of newline separators are supported (in the same string even).
I've had the same symptoms.
Only diff that it happened only during docker-compose build
docker ps
worked.
Happened with version 2.x
as well as 3.x
.
Restarted docker
service, then the machine...
Even re-installed docker
+ docker-compose
.
Tried everything but nothing helped.
Finally I tried building the Dockerfile "manually" by using docker build
.
Apparently I had a permission issue on a file/folder inside the Docker
context. It was trying to read the context when starting the build and failed with a proper error message.
However this error message did not propagate to docker-compose
which only shows Couldn't connect to Docker daemon at http+unix://var/run/docker.sock - is it running?
Having found that the solution was simply adding the file/folder to the .dockerignore
file since it wasn't needed for the build. Another solution might have been to chown
or chmod
it.
Anyway maybe this could help someone coming across the same issue that really has nothing to do with docker
and the misleading error message being displayed.
If you using JavaScript to test your Regex, try \\.
instead of \.

It acts on the same way because JS remove first backslash.
As of release 1.7 Dashboard supports user authentication based on:
Authorization: Bearer <token>
header passed in every request to Dashboard. Supported from release 1.6. Has the highest priority. If present, login view will not be shown.- Bearer Token that can be used on Dashboard login view.
- Username/password that can be used on Dashboard login view.
- Kubeconfig file that can be used on Dashboard login view.
Here Token
can be Static Token
, Service Account Token
, OpenID Connect Token
from Kubernetes Authenticating, but not the kubeadm Bootstrap Token
.
With kubectl, we can get an service account (eg. deployment controller) created in kubernetes by default.

kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: kubernetes-dashboard
namespace: kube-system
EOF
Afterwards you can use Skip option on login page to access Dashboard.
If you are using dashboard version v1.10.1 or later, you must also add --enable-skip-login
to the deployment's command line arguments. You can do so by adding it to the args
in kubectl edit deployment/kubernetes-dashboard --namespace=kube-system
.
Example:
containers:
- args:
- --auto-generate-certificates
- --enable-skip-login # <-- add this line
image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1
this way worked better for me:
echo y | keytool -storepasswd -storepass 123456 -keystore /tmp/IT-Root-CA.keystore -import -alias IT-Root-CA -file /etc/pki/ca-trust/source/anchors/IT-Root-CA.crt
machine running:

If you using angular-cli Keep the json file inside Assets folder (parallel to app dir) directory
return this.http.get('<json file path inside assets folder>.json'))
.map((response: Response) => {
console.log("mock data" + response.json());
return response.json();
}
)
.catch(this.handleError);
}
Note: here you only need to give path inside assets folder like assets/json/oldjson.json then you need to write path like /json/oldjson.json
If you using webpack then you need to follow above same structure inside public folder its similar like assets folder.
data = str(input("Please type a sentence: "))
vowels = "aeiou"
for v in vowels:
print(v, data.lower().count(v))
I had a similar problem.
Issue was there was a trigger on the table that would write changes to an audit log table. Columns were missing in audit log table.
Try:
$counter = 0;
foreach ($Contents as $item) {
something
your code ...
$counter++;
}
$total_count=$counter-1;
this should be an internal file of JRE and in general you shouldn't deal with it when you're running/compiling java.
Here you can find an explanation of what exactly this file is intended for. Bottom line, your Java installation is somehow corrupted, so as a first resort to resolve this issue, I suggest you to re-install jre.
You should ensure that you're installing the right jre for your architecture.
Hope, this helps
Here is how I fixed this on my Windows (7) Dev. environment. I assume the following...
Okay, let's get to it:
Update any packages where a version check is returning a warning ("npm WARN"..) for example...
npm update -g npm
npm update -g graceful-fs
Next we want to force a cache clean. This is flagged by an '--f' or '-f'..
npm cache clean --f
In Widows Explorer search for the following path
%APPDATA%\npm-cache
And Delete it's contents
Hope this helps someone!!
My solution is: date('Y-m-d', time()-60*60*24*365);
You can make it more "readable" with defines:
define('ONE_SECOND', 1);
define('ONE_MINUTE', 60 * ONE_SECOND);
define('ONE_HOUR', 60 * ONE_MINUTE);
define('ONE_DAY', 24 * ONE_HOUR);
define('ONE_YEAR', 365 * ONE_DAY);
date('Y-m-d', time()-ONE_YEAR);
If you want the runtime to supply a default parameter value, you have to use reflection to make the call. Not as nice as the other suggestions for this question, but compatible with VB.NET.
using System;
using System.Runtime.InteropServices;
using System.Reflection;
namespace ConsoleApplication1
{
class Class1
{
public static void sayHelloTo(
[Optional,
DefaultParameterValue("world")] string whom)
{
Console.WriteLine("Hello " + whom);
}
[STAThread]
static void Main(string[] args)
{
MethodInfo mi = typeof(Class1).GetMethod("sayHelloTo");
mi.Invoke(null, new Object[] { Missing.Value });
}
}
}
The initial width of a block level element like div or p is auto.
Use width:auto to undo explicitly specified widths.
if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border.
So, next time you find yourself setting the width of a block level element to 100% to make it occupy all available width, consider if what you really want is setting it to auto.
It's little too late but this really works for me.
react-native run-android
.react-native start
.First command will build apk
for android and deploy it on your device if its connected. When you open the App it will show red screen with error. Then run second command which will run packager and build app bundle for you.
During migration from Ubuntu 12.04 to 14.04 I stumbled over this as well and wanted to share that as of Ubuntu 14.04 LTS the IMAP extension seems no longer to be loaded per default.
Check to verify if the extension is installed:
dpkg -l | grep php5-imap
should give a response like this:
ii php5-imap 5.4.6-0ubuntu5 amd64 IMAP module for php5
if not, install it.
To actually enable the extension
cd /etc/php5/apache2/conf.d
ln -s ../../mods-available/imap.ini 20-imap.ini
service apache2 restart
should fix it for apache. For CLI do the same in /etc/php5/cli/conf.d
The DictWriter()
class expects dictionaries for each row. If all you wanted to do was write an initial header, use a regular csv.writer()
and pass in a simple row for the header:
import csv
with open('combined_file.csv', 'w', newline='') as outcsv:
writer = csv.writer(outcsv)
writer.writerow(["Date", "temperature 1", "Temperature 2"])
with open('t1.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows(row + [0.0] for row in reader)
with open('t2.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows(row[:1] + [0.0] + row[1:] for row in reader)
The alternative would be to generate dictionaries when copying across your data:
import csv
with open('combined_file.csv', 'w', newline='') as outcsv:
writer = csv.DictWriter(outcsv, fieldnames = ["Date", "temperature 1", "Temperature 2"])
writer.writeheader()
with open('t1.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows({'Date': row[0], 'temperature 1': row[1], 'temperature 2': 0.0} for row in reader)
with open('t2.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows({'Date': row[0], 'temperature 1': 0.0, 'temperature 2': row[1]} for row in reader)
In LINQ2SQL you seldom need to join explicitly when using inner joins.
If you have proper foreign key relationships in your database you will automatically get a relation in the LINQ designer (if not you can create a relation manually in the designer, although you should really have proper relations in your database)
Then you can just access related tables with the "dot-notation"
var q = from child in context.Childs
where child.Parent.col2 == 4
select new
{
childCol1 = child.col1,
parentCol1 = child.Parent.col1,
};
will generate the query
SELECT [t0].[col1] AS [childCol1], [t1].[col1] AS [parentCol1]
FROM [dbo].[Child] AS [t0]
INNER JOIN [dbo].[Parent] AS [t1] ON ([t1].[col1] = [t0].[col1]) AND ([t1].[col2] = [t0].[col2])
WHERE [t1].[col2] = @p0
-- @p0: Input Int (Size = -1; Prec = 0; Scale = 0) [4]
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 4.0.30319.1
In my opinion this is much more readable and lets you concentrate on your special conditions and not the actual mechanics of the join.
Edit
This is of course only applicable when you want to join in the line with our database model. If you want to join "outside the model" you need to resort to manual joins as in the answer from Quintin Robinson
For me it helped to register a button that calls code behind code as a postback control.
protected void Page_Init(object sender, EventArgs e)
{
ScriptManager.GetCurrent(this.Page).RegisterPostBackControl(btnMyExport);
}
Use the shell error handling for unset variables (note the double $
):
$ cat Makefile
foo:
echo "something is set to $${something:?}"
$ make foo
echo "something is set to ${something:?}"
/bin/sh: something: parameter null or not set
make: *** [foo] Error 127
$ make foo something=x
echo "something is set to ${something:?}"
something is set to x
If you need a custom error message, add it after the ?
:
$ cat Makefile
hello:
echo "hello $${name:?please tell me who you are via \$$name}"
$ make hello
echo "hello ${name:?please tell me who you are via \$name}"
/bin/sh: name: please tell me who you are via $name
make: *** [hello] Error 127
$ make hello name=jesus
echo "hello ${name:?please tell me who you are via \$name}"
hello jesus
Build Path -> Configure Build Path -> Libraries (Tab) -> Add Class Folder, then select your folder or create one.
public void onClick(View v)

it is direct way to move second activity and there is no need for call intent
I think you should use "textAlign" instead of "text-align".
As suggested before, you can either use:
import matplotlib.pyplot as plt
plt.savefig("myfig.png")
For saving whatever IPhython image that you are displaying. Or on a different note (looking from a different angle), if you ever get to work with open cv, or if you have open cv imported, you can go for:
import cv2
cv2.imwrite("myfig.png",image)
But this is just in case if you need to work with Open CV. Otherwise plt.savefig() should be sufficient.
As with all good examples, you've simplified what you're actually trying to do. This is good, but it is worth noting that python has a lot of flexibility when it comes to class versus instance variables. The same can be said of methods. For a good list of possibilities, I recommend reading Michael Fötsch' new-style classes introduction, especially sections 2 through 6.
One thing that takes a lot of work to remember when getting started is that python is not java. More than just a cliche. In java, an entire class is compiled, making the namespace resolution real simple: any variables declared outside a method (anywhere) are instance (or, if static, class) variables and are implicitly accessible within methods.
With python, the grand rule of thumb is that there are three namespaces that are searched, in order, for variables:
{begin pedagogy}
There are limited exceptions to this. The main one that occurs to me is that, when a class definition is being loaded, the class definition is its own implicit namespace. But this lasts only as long as the module is being loaded, and is entirely bypassed when within a method. Thus:
>>> class A(object):
foo = 'foo'
bar = foo
>>> A.foo
'foo'
>>> A.bar
'foo'
but:
>>> class B(object):
foo = 'foo'
def get_foo():
return foo
bar = get_foo()
Traceback (most recent call last):
File "<pyshell#11>", line 1, in <module>
class B(object):
File "<pyshell#11>", line 5, in B
bar = get_foo()
File "<pyshell#11>", line 4, in get_foo
return foo
NameError: global name 'foo' is not defined
{end pedagogy}
In the end, the thing to remember is that you do have access to any of the variables you want to access, but probably not implicitly. If your goals are simple and straightforward, then going for Foo.bar or self.bar will probably be sufficient. If your example is getting more complicated, or you want to do fancy things like inheritance (you can inherit static/class methods!), or the idea of referring to the name of your class within the class itself seems wrong to you, check out the intro I linked.
You need to setup your app to run over https for localhost
You can follow steps given in this to setup HTTPS on ubuntu
You need to do following steps:
install apache (if you do not have)
sudo apt-get install apache2
Step One—Activate the SSL Module
sudo a2enmod ssl
sudo service apache2 restart
Step Two—Create a New Directory
sudo mkdir /etc/apache2/ssl
Step Three—Create a Self Signed SSL Certificate
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache/ssl/apache.key -out /etc/apache2/ssl/apache.crt
With this command, we will be both creating the self-signed SSL certificate and the server key that protects it, and placing both of them into the new directory. The most important line is "Common Name". Enter your official domain name here or, if you don't have one yet, your site's IP address.
Common Name (e.g. server FQDN or YOUR name) []:example.com or localhost
Step Four—Set Up the Certificate
sudo vim /etc/apache2/sites-available/default-ssl
Find following lines and edit those with your settings
ServerName localhost or example.com
SSLEngine on SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
Step Five—Activate the New Virtual Host
sudo a2ensite default-ssl
sudo service apache2 reload
in python sorted
works like you want with integers:
>>> sorted([10,3,2])
[2, 3, 10]
it looks like you have a problem because you are using strings:
>>> sorted(['10','3','2'])
['10', '2', '3']
(because string ordering starts with the first character, and "1" comes before "2", no matter what characters follow) which can be fixed with key=int
>>> sorted(['10','3','2'], key=int)
['2', '3', '10']
which converts the values to integers during the sort (it is called as a function - int('10')
returns the integer 10
)
and as suggested in the comments, you can also sort the list itself, rather than generating a new one:
>>> l = ['10','3','2']
>>> l.sort(key=int)
>>> l
['2', '3', '10']
but i would look into why you have strings at all. you should be able to save and retrieve integers. it looks like you are saving a string when you should be saving an int? (sqlite is unusual amongst databases, in that it kind-of stores data in the same type as it is given, even if the table column type is different).
and once you start saving integers, you can also get the list back sorted from sqlite by adding order by ...
to the sql command:
select temperature from temperatures order by temperature;
Off hand the code looks right. What if you try using an 'Else' and see what happens?
IF @SchoolCategoryCode = 'Elem'
--- We now have determined we are processing an elementary school...

IF @Term = 3
BEGIN
INSERT INTO @Classes
SELECT
XXXXXX
FROM XXXX blah blah blah
INSERT INTO @Classes
SELECT
XXXXXXXX
FROM XXXXXX (more code)
END <----(Should this be ENDIF?)
ELSE
BEGIN
INSERT INTO @Classes
SELECT
XXXXXXXX
FROM XXXXXX (more code)
END
END
SimpleDateFormat
stores intermediate results in instance fields. So if one instance is used by two threads they can mess each other's results.
Looking at the source code reveals that there is a Calendar
instance field, which is used by operations on DateFormat
/ SimpleDateFormat
.
For example parse(..)
calls calendar.clear()
initially and then calendar.add(..)
. If another thread invokes parse(..)
before the completion of the first invocation, it will clear the calendar, but the other invocation will expect it to be populated with intermediate results of the calculation.
One way to reuse date formats without trading thread-safety is to put them in a ThreadLocal
- some libraries do that. That's if you need to use the same format multiple times within one thread. But in case you are using a servlet container (that has a thread pool), remember to clean the thread-local after you finish.
To be honest, I don't understand why they need the instance field, but that's the way it is. You can also use joda-time DateTimeFormat
which is threadsafe.
Create a general useOnOutsideClick function
export const useOnOutsideClick = handleOutsideClick => {
const innerBorderRef = useRef();
const onClick = event => {
if (
innerBorderRef.current &&
!innerBorderRef.current.contains(event.target)
) {
handleOutsideClick();
}
};
useMountEffect(() => {
document.addEventListener("click", onClick, true);
return () => {
document.removeEventListener("click", onClick, true);
};
});
return { innerBorderRef };
};
const useMountEffect = fun => useEffect(fun, []);
Then use the hook in any functional component.
const OutsideClickDemo = ({ currentMode, changeContactAppMode }) => {
const [open, setOpen] = useState(false);
const { innerBorderRef } = useOnOutsideClick(() => setOpen(false));
return (
<div>
<button onClick={() => setOpen(true)}>open</button>
{open && (
<div ref={innerBorderRef}>
<SomeChild/>
</div>
)}
</div>
);
};
Partially inspired by @pau1fitzgerald answer.
You might be able to do this with AutoGenerateColumns and a DataTemplate. I'm not positive if it would work without a lot of work, you would have to play around with it. Honestly if you have a working solution already I wouldn't make the change just yet unless there's a big reason. The DataGrid control is getting very good but it still needs some work (and I have a lot of learning left to do) to be able to do dynamic tasks like this easily.
By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.
In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.
The client code must set the withCredentials
property on the XMLHttpRequest
to true
in order to give permission.
However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials
header. Responding with this header to true
means that the server allows cookies (or other user credentials) to be included on cross-origin requests.
You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.
Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).
There are a lot of different ways to look at this decision from development, IT, and business objectives, so don't feel bad if it seems overwhelming. But also - don't overthink scalability.
Think about your requirements.
I've engineered websites which have serviced over 8M uniques a day and delivered terabytes of video a week built on infrastructures starting at $250k in capital hardware unr by a huge $MM IT labor staff.
But I've also had smaller websites which were designed to generate $10-$20k per year, didn't have very high traffic, db or processing requirements, and I ran those off a $10/mo generic hosting account without compromise.
In the future, deployment will look more like Heroku than AWS, just because of progress. There is zero value in the IT knob-turning of scaling internet infrastructures which isn't increasingly automatable, and none of it has anything to do with the value of the product or service you are offering.
Also, keep in mind with a commercial website - scalability is what we often call a 'good problem to have' - although scalability issues with sites like Facebook and Twitter were very high-profile, they had zero negative effect on their success - the news might have even contributed to more signups (all press is good press).
If you have a service which is generating a 100k+ uniques a day and having scaling issues, I'd be glad to take it off your hands for you no matter what the language, db, platform, or infrastructure you are running on!
Scalability is a fixable implementation problem - not having customers is an existential issue.
Yes dear,then you have to use Ajax technology. to changes contents of particular html tag:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<title>Ajax Page</title>
<script>
setInterval(function () { autoloadpage(); }, 30000); // it will call the function autoload() after each 30 seconds.
function autoloadpage() {
$.ajax({
url: "URL of the destination page",
type: "POST",
success: function(data) {
$("div#wrapper").html(data); // here the wrapper is main div
}
});
}
</script>
</head>
<body>
<div id="wrapper">
contents will be changed automatically.
</div>
</body>

}
All the answers so far retain local commits. If you're really serious, you can discard all local commits and all local edits by doing:
git reset --hard origin/branchname
For example:
git reset --hard origin/master
This makes your local repository exactly match the state of the origin (other than untracked files).
If you accidentally did this after just reading the command, and not what it does :), use git reflog to find your old commits.
In java you can do some thing like:
if(driver.getTitle().contains("some expected text"))
//Pass
System.out.println("Page title contains \"some expected text\" ");
else
//Fail
System.out.println("Page title doesn't contains \"some expected text\" ");
I've had a few cranberry-vodkas tonight so I might be missing something...Is setting the range necessary? Why not use:
Activeworkbook.Sheets("Game").Range("A1").value = "Subtotal"
Does this fail as well?
Looks like you tried something similar:
'Worksheets("Game").Range("A1") = "Asdf"
However, Worksheets is a collection, so you can't reference "Game". I think you need to use the Sheets object instead.
For MySql WorkBench, Please use below :

Here is an elegant library that records video in all supported browsers and supports uploading:

This helped me get to my answer. There are two php.ini
files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin
folder. When connecting to SQL through sqlsrv_connect
function, we are referring to the php.ini
file in the apache
folder. Add the following (as per your version) to this file:
extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll
This man have the best solution. Only css:
.multiline-ellipsis {

If Java is installed on your 11G then you can do it in a java class and call it from your PL/SQL, but I am not sure that it does not require also a specific grant to call java.
The line should be:
numpy.concatenate([a,b])
The arrays you want to concatenate need to be passed in as a sequence, not as separate arguments.
From the NumPy documentation:
numpy.concatenate((a1, a2, ...), axis=0)
Join a sequence of arrays together.
It was trying to interpret your b
as the axis parameter, which is why it complained it couldn't convert it into a scalar.

The expression 'AND' and 'OR' and 'NOT'
always evaluates to 'NOT'
, so you are effectively doing
while 'NOT' not in some_list:
print 'No boolean operator'
You can either check separately for all of them
while ('AND' not in some_list and
'OR' not in some_list and
'NOT' not in some_list):
# whatever
or use sets
s = set(["AND", "OR", "NOT"])
while not s.intersection(some_list):
# whatever
See http://jsfiddle.net/qP8DY/24/
You can add a class (such as "success-dialog" in my example) to div#success, either directly in your HTML, or in your JavaScript by adding to the dialogClass option, as I've done.
$('#success').dialog({
height: 50,
width: 350,
modal: true,
resizable: true,
dialogClass: 'no-close success-dialog'
});
Then just add the success-dialog class to your CSS rules as appropriate. To indicate an element with two (or more) classes applied to it, just write them all together, with no spaces in between. For example:
.ui-dialog.success-dialog {
font-family: Verdana,Arial,sans-serif;
font-size: .8em;
}
Reading the value (not the text) of a select:
var status = $("#Status").val();
var status = $("#Status")[0].value;
var status = $('#Status option:selected').val();
How to disable a select? in both variants, value can be changed using:
A
User can not interact with the dropdown. And he doesn't know what other options might exists.
$('#Status').prop('disabled', true);
B
User can see the options in the dropdown but all of them are disabled:
$('#Status option').attr('disabled', true);
In this case, $("#Status").val()
will only work for jQuery versions smaller than 1.9.0
. All other variants will work.
How to update a disabled select?
From code behind you can still update the value in your select. It is disabled only for users:
$("#Status").val(2);
In some cases you might need to fire events:
$("#Status").val(2).change();

How are you running the application? Are you just hitting the website or are you building and running from within Visual Studio? If you are building and running you may want to tell it to use the local IIS web server. This would make sure it is using the App Pool you have set up to run with v4.0/integrated.
I am guessing that it is using the Visual Studio Development Server when running. This server is probably trying to run with the 2.0 framework. This then causes your error to be thrown.
Edit: To note, I normally just build my website application and then I attach to process w3wp when I want to debug. I do not use the publishing tool. Of course this means my local working directory is within the web root.
The li
tag has a property called list-style-position
. This makes your bullets inside or outside the list. On default, it’s set to inside
. That makes your text wrap around it. If you set it to outside
, the text of your li
tags will be aligned.
The downside of that is that your bullets won't be aligned with the text outside the ul
. If you want to align it with the other text you can use a margin.
ul li {
/*
* We want the bullets outside of the list,
* so the text is aligned. Now the actual bullet
* is outside of the list’s container
*/
list-style-position: outside;
/*

If you have a named container then it can be started by running
docker container start container_name
where container_name is name of the container that must be given at the time of creating container. You can replace container_name
with the container id in case the container is not named. The container ID can be found by running:
docker ps -a
Example: index = False
import pandas as pd
writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save()
import csv
with open(file_path, 'a') as outcsv:
#configure writer to write standard csv file
writer = csv.writer(outcsv, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL, lineterminator='\n')
writer.writerow(['number', 'text', 'number'])
for item in list:
#Write item to outcsv
writer.writerow([item[0], item[1], item[2]])

Generate Unique ID Using Java
UUID is the fastest and easiest way to generate unique ID in Java.
import java.util.UUID;
public class UniqueIDTest {
public static void main(String[] args) {
UUID uniqueKey = UUID.randomUUID();
System.out.println (uniqueKey);
}
}
This worked much better in my case.

shortest and simplified version of @Rosdi Kasim'd answer is
string claimvalue = ((System.Security.Claims.ClaimsIdentity)User.Identity).
FindFirst("claimname").Value;
Claimname
is the claim you want to retrieve i.e if you are looking for "StreedAddress" claim then the above answer will be like this
string claimvalue = ((System.Security.Claims.ClaimsIdentity)User.Identity).
FindFirst("StreedAddress").Value;
GRANT
s on different objects are separate. GRANT
ing on a database doesn't GRANT
rights to the schema within. Similiarly, GRANT
ing on a schema doesn't grant rights on the tables within.
If you have rights to SELECT
from a table, but not the right to see it in the schema that contains it then you can't access the table.
The rights tests are done in order:
Do you have `USAGE` on the schema?
No: Reject access.
Yes: Do you also have the appropriate rights on the table?
No: Reject access.
Yes: Check column privileges.
Your confusion may arise from the fact that the public
schema has a default GRANT
of all rights to the role public
, which every user/group is a member of. So everyone already has usage on that schema.
The phrase:
(assuming that the objects' own privilege requirements are also met)
Is saying that you must have USAGE
on a schema to use objects within it, but having USAGE
on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.
It's like a directory tree. If you create a directory somedir
with file somefile
within it then set it so that only your own user can access the directory or the file (mode rwx------
on the dir, mode rw-------
on the file) then nobody else can list the directory to see that the file exists.
If you were to grant world-read rights on the file (mode rw-r--r--
) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.
If you instead set rwx-r-xr-x
on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.
You need to set both permissions for people to actually be able to view the file.
Same thing in Pg. You need both schema USAGE
rights and object rights to perform an action on an object, like SELECT
from a table.
(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECT
ing from pg_class
directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)
Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)
Do it the other way around:
$a = "1,435";
$b = str_replace( ',', '', $a );
if( is_numeric( $b ) ) {
$a = $b;
}
The easiest would be:
$var = intval(preg_replace('/[^\d.]/', '', $var));
or if you need float:
$var = floatval(preg_replace('/[^\d.]/', '', $var));
I'm now using Oracle with Java. Here my point of view :
You should close ResultSet
and Statement
explicitly because Oracle has problems previously with keeping the cursors open even after closing the connection. If you don't close the ResultSet
(cursor) it will throw an error like Maximum open cursors exceeded.
I think you may encounter with the same problem with other databases you use.
Here is tutorial Close ResultSet when finished:
Close ResultSet when finished
Close
ResultSet
object as soon as you finish working withResultSet
object even thoughStatement
object closes theResultSet
object implicitly when it closes, closingResultSet
explicitly gives chance to garbage collector to recollect memory as early as possible becauseResultSet
object may occupy lot of memory depending on query.
ResultSet.close();
The answer with the higher vote has a mistake. when I used it I find out it in line 3 :
var counter = jsonData.counters[i];
I changed it to :
var counter = jsonData[i].counters;
and it worked for me. There is a difference to the other answers in line 3:
var jsonData = JSON.parse(myMessage);
for (var i = 0; i < jsonData.counters.length; i++) {
var counter = jsonData[i].counters;
console.log(counter.counter_name);
}
In Swift 4.2 I would do something like that:
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let yourVC = segue.destination as? YourViewController {
yourVC.yourData = self.someData
}
}
For no InnoDB solution: you can use a procedure
don't forgot to set the delimiter for storing the procedure with ;
CREATE PROCEDURE myproc(OUT id INT, IN otherid INT, IN title VARCHAR(255))
BEGIN
LOCK TABLES `table1` WRITE;
INSERT INTO `table1` ( `title` ) VALUES ( @title );
SET @id = LAST_INSERT_ID();
UNLOCK TABLES;
INSERT INTO `table2` ( `parentid`, `otherid`, `userid` ) VALUES (@id, @otherid, 1);
END
And you can use it...
SET @myid;
CALL myproc( @myid, 1, "my title" );
SELECT @myid;
Nice short method:
public static String escapeHTML(String s) {
StringBuilder out = new StringBuilder(Math.max(16, s.length()));
for (int i = 0; i < s.length(); i++) {
char c = s.charAt(i);
if (c > 127 || c == '"' || c == '\'' || c == '<' || c == '>' || c == '&') {
out.append("&#");
out.append((int) c);
out.append(';');
} else {
out.append(c);
}
}
return out.toString();
}
Based on https://stackoverflow.com/a/8838023/1199155 (the amp is missing there). The four characters checked in the if clause are the only ones below 128, according to http://www.w3.org/TR/html4/sgml/entities.html
This error can also show up if there are parts in your string that json.loads()
does not recognize. An in this example string, an error will be raised at character 27 (char 27)
.
string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""
My solution to this would be to use the string.replace()
to convert these items to a string:
import json
string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""
string = string.replace("False", '"False"')
dict_list = json.loads(string)

Taken from: http://www.w3.org/Style/Examples/007/units:
The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion. Declarations such as 'text-indent: 1.5em' and 'margin: 1em' are extremely common in CSS.
em
is basically CSS property for font sizes.
If you want to use 1 image and display it in different size, you can use scale drawable ( http://developer.android.com/guide/topics/resources/drawable-resource.html#Scale ).
A move from WebForms to MVC requires a complete sea-change in logic and brain processes. You're no longer interacting with the 'form' both server-side and client-side (and in fact even with WebForms you weren't interacting client-side). You've probably just mixed up a bit of thinking there, in that with WebForms and RUNAT="SERVER"
you were merely interacting with the building of the Web page.
MVC is somewhat similar in that you have server-side code in constructing the model (the data you need to build what your user will see), but once you have built the HTML you need to appreciate that the link between the server and the user no longer exists. They have a page of HTML, that's it.
So the HTML you are building is read-only. You pass the model through to the Razor page, which will build HTML appropriate to that model.
If you want to have a hidden element which sets true or false depending on whether this is the first view or not you need a bool in your model, and set it to True in the Action if it's in response to a follow up. This could be done by having different actions depending on whether the request is [HttpGet] or [HttpPost] (if that's appropriate for how you set up your form: a GET request for the first visit and a POST request if submitting a form).
Alternatively the model could be set to True when it's created (which will be the first time you visit the page), but after you check the value as being True or False (since a bool defaults to False when it's instantiated). Then using:
@Html.HiddenFor(x => x.HiddenPostBack)
in your form, which will put a hidden True. When the form is posted back to your server the model will now have that value set to True.
It's hard to give much more advice than that as your question isn't specific as to why you want to do this. It's perhaps vital that you read a good book on moving to MVC from WebForms, such as Steve Sanderson's Pro ASP.NET MVC.
When solving Stacking modals scrolls the main page when one is closed i found that newer versions of Bootstrap (at least since version 3.0.3) do not require any additional code to stack modals.
You can add more than one modal (of course having a different ID) to your page. The only issue found when opening more than one modal will be that closing one remove the modal-open
class for the body selector.
You can use the following Javascript code to re-add the modal-open
:
$('.modal').on('hidden.bs.modal', function (e) {
if($('.modal').hasClass('in')) {
$('body').addClass('modal-open');
}
});
In the case that do not need the backdrop effect for the stacked modal you can set data-backdrop="false"
.
Version 3.1.1. fixed Fix modal backdrop overlaying the modal's scrollbar, but the above solution seems also to work with earlier versions.

Push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:
git config --global push.default matching
To squelch this message and adopt the new behavior now, use:
git config --global push.default simple
When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.
Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.

I believe the Id column in your SQL Table isn't a identity column.
If this is happening to you with Android 6 and compile target >= 23, don't forget that we are now using runtime permissions. So giving permissions in the manifest is not enough anymore.
Don't over complicate it. Just give the link a color using the tags. It will leave a constant color that won't change even if you click it. So in your case just set it to blue. If it is set to a particular color of blue just you want to copy, you can press "print scrn" on your keyboard, paste in paint, and using the color picker(shaped as a dropper) pick the color of the link and view the code in the color settings.
If you're using a Mac -
Connect your iPhone to your Mac via USB.
Go to Network Utility (cmd+space and type "network utility")
Go to the "Info" tab
Click on the drop down menu that says "Wi-Fi" and select "iPhone USB" as shown in the photo.
You'll find an IP address like "xxx.xxx.xx.xx" or similar. Open Safari browser on your iPhone and enter IP_address:port_number
Example: 169.254.72.86:3000
[NOTE: If the IP address field is blank, make sure your iPhone is connected via USB, quit Network Utility, open it again and check for the IP address.]
Make a temporary copy of your working copy, then merge into that, and diff the two.

Here is how we solved it
a Users table looked like this
Users
-------------------------------------------------
id | name | address | phone | email | created_on | updated_on
And the business requirement changed and we were in a need to check all previous addresses and phone numbers a user ever had. new schema looks like this
Users (the data that won't change over time)
-------------
id | name
UserData (the data that can change over time and needs to be tracked)
-------------------------------------------------
id | id_user | revision | city | address | phone | email | created_on
1 | 1 | 0 | NY | lake st | 9809 | @long | 2015-10-24 10:24:20
2 | 1 | 2 | Tokyo| lake st | 9809 | @long | 2015-10-24 10:24:20
3 | 1 | 3 | Sdny | lake st | 9809 | @long | 2015-10-24 10:24:20
4 | 2 | 0 | Ankr | lake st | 9809 | @long | 2015-10-24 10:24:20
5 | 2 | 1 | Lond | lake st | 9809 | @long | 2015-10-24 10:24:20
To find the current address of any user, we search for UserData with revision DESC and LIMIT 1
To get the address of a user between a certain period of time we can use created_on bewteen (date1 , date 2)

By reading online (tables tutorial) it seems tables behave like arrays so you're looking for:
Way1
names = {'John', 'Joe', 'Steve'}
for i = 1,3 do print( names[i] ) end
Way2
names = {'John', 'Joe', 'Steve'}
for k,v in pairs(names) do print(v) end
Way1 uses the table index/key
, on your table names
each element has a key starting from 1, for example:
names = {'John', 'Joe', 'Steve'}
print( names[1] ) -- prints John
So you just make i
go from 1 to 3.
On Way2 instead you specify what table you want to run and assign a variable for its key and value for example:
names = {'John', 'Joe', myKey="myValue" }
for k,v in pairs(names) do print(k,v) end
prints the following:
1 John
2 Joe
myKey myValue
This writes a Byte Order Mark at the start of the file, which is unnecessary in a UTF-8 file and some applications (in my case, SAP) don't like it. Solution here: Can I export excel data with UTF-8 without BOM?
Your model is @Messages
, change it to @message
.
To change it like you should use migration:
def change rename_table :old_table_name, :new_table_name end
Of course do not create that file by hand but use rails generator:
rails g migration ChangeMessagesToMessage
That will generate new file with proper timestamp in name in 'db
dir. Then run:
rake db:migrate
And your app should be fine since then.
I solved this by tacking a last modified timestamp as a query parameter to the scripts.
I did this with an extension method, and using it in my CSHTML files. Note: this implementation caches the timestamp for 1 minute so we don't thrash the disk quite so much.
Here is the extension method:
public static class JavascriptExtension {
public static MvcHtmlString IncludeVersionedJs(this HtmlHelper helper, string filename) {
string version = GetVersion(helper, filename);
return MvcHtmlString.Create("<script type='text/javascript' src='" + filename + version + "'></script>");
}
private static string GetVersion(this HtmlHelper helper, string filename)
{
var context = helper.ViewContext.RequestContext.HttpContext;
if (context.Cache[filename] == null)
{
var physicalPath = context.Server.MapPath(filename);
var version = $"?v={new System.IO.FileInfo(physicalPath).LastWriteTime.ToString("MMddHHmmss")}";
context.Cache.Add(filename, version, null,
DateTime.Now.AddMinutes(5), TimeSpan.Zero,
CacheItemPriority.Normal, null);
return version;
}
else
{
return context.Cache[filename] as string;
}
}
}
And then in the CSHTML page:
@Html.IncludeVersionedJs("/MyJavascriptFile.js")
In the rendered HTML, this appears as:
<script type='text/javascript' src='/MyJavascriptFile.js?20111129120000'></script>
Use Datatable.Default.Sort
property and then bind it to the datagridview.
When I want to access the application file version (what is set in Assembly Information -> File version), say to set a label's text to it on form load to display the version, I have just used
versionlabel.Text = "Version " + Application.ProductVersion;
This approach requires a reference to System.Windows.Forms
.
Another option is just running up the first module with the 'docker-compose' check the ip related with the module, and connect the second module with the previous net like external, and pointing the internal ip
example app1 - new-network created in the service lines, mark as external: true at the bottom app2 - indicate the "new-network" created by app1 when goes up, mark as external: true at the bottom, and set in the config to connect, the ip that app1 have in this net.
With this, you should be able to talk with each other
*this way is just for local-test focus, in order to don't do an over complex configuration ** I know is very 'patch way' but works for me and I think is so simple some other can take advantage of this
Use an Application that implements ActivityLifecycleCallbacks and use it to track Activities lifecycle events in you application. Note that ActivityLifecycleCallbacks are for Android api >= 14. For previous Android api, you'll need to implement it by yourself inside all of your activities ;-)
Use Application when you need to share / store states accross activities.
You can check the status of a running process with this class RunningAppProcessInfo
Fetch the running process list with ActivityManager.getRunningAppProcesses() and filter the result list to check for the desired RunningAppProcessInfo and check its "importance"
sequenceName
is the name of the sequence in the DB. This is how you specify a sequence that already exists in the DB. If you go this route, you have to specify the allocationSize
which needs to be the same value that the DB sequence uses as its "auto increment".
Usage:
@GeneratedValue(generator="my_seq")
@SequenceGenerator(name="my_seq",sequenceName="MY_SEQ", allocationSize=1)
If you want, you can let it create a sequence for you. But to do this, you must use SchemaGeneration to have it created. To do this, use:
@GeneratedValue(strategy=GenerationType.SEQUENCE)
Also, you can use the auto-generation, which will use a table to generate the IDs. You must also use SchemaGeneration at some point when using this feature, so the generator table can be created. To do this, use:
@GeneratedValue(strategy=GenerationType.AUTO)
