sometimes even after clearing border
s.
the reason is that you have images inside the td
, giving the images display:block
solves it.
You can also do this much easier with a plugin called jQuery-confirm. All you have to do is add the script tag and the style sheet they provide in your page
<link rel="stylesheet"
href="https://cdnjs.cloudflare.com/ajax/libs/jquery-
confirm/3.3.0/jquery-confirm.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-
confirm/3.3.0/jquery-confirm.min.js"></script>
And then an example of calling the alert box is:
<script>
$.alert({
title: 'Alert!',
content: 'Simple alert!',
});
Try this:
while read line
do
echo -e |wc -m
done <abc.txt
As we want to only separate lines, and the writelines
function in python does not support adding separator between lines, I have written the simple code below which best suits this problem:
sep = "\n" # defining the separator
new_lines = sep.join(lines) # lines as an iterator containing line strings
and finally:
with open("file_name", 'w') as file:
file.writelines(new_lines)
and you are done.
Even after double quotes, I had this problem for a few days.
Replaced Pipe Delimiter with Comma, then things worked fine.
As addition of good answers, You don't have to use [FromForm]
to get form data in controller. Framework automatically convert form data to model as you wish. You can implement like following.
[HttpPost]
public async Task<IActionResult> Submit(MyModel model)
{
//...
}
use return Observable.of(HEROES);
My 2cents because the comments for the only answer are getting kinda crazy. This is what I normally do. For a circle, you need to start with a square. This code forces a square and will stretch the image. If you know that the image is going to be at least the width and height of the round div you can remove the img
style rules for it to not be stretch but only cut off.
<html>
<head>
<style>
.round {
border-radius: 50%;
overflow: hidden;
width: 150px;
height: 150px;
}
.round img {
display: block;
/* Stretch
height: 100%;
width: 100%; */
min-width: 100%;
min-height: 100%;
}
</style>
</head>
<body>
<div class="round">
<img src="image.jpg" />
</div>
</body>
</html>
os.system ('/home/user1/exportPath.ksh')
exportPath.ksh:
export PATH=MY_DATA="my_export"
Try this
<input onclick="confirmSubmit(event);" type="button" value="Send" />
Along with this
function confirmSubmit(event){
var domElement =$(event.target);
console.log(domElement.attr('type'));
}
I tried it in firefox, it prints the 'type' attribute of dom Element clicked. I guess you can then get the form via the parents() methods using this object.
RANK gives you the ranking within your ordered partition. Ties are assigned the same rank, with the next ranking(s) skipped. So, if you have 3 items at rank 2, the next rank listed would be ranked 5.
DENSE_RANK again gives you the ranking within your ordered partition, but the ranks are consecutive. No ranks are skipped if there are ranks with multiple items.
As for nulls, it depends on the ORDER BY clause. Here is a simple test script you can play with to see what happens:
with q as (
select 10 deptno, 'rrr' empname, 10000.00 sal from dual union all
select 11, 'nnn', 20000.00 from dual union all
select 11, 'mmm', 5000.00 from dual union all
select 12, 'kkk', 30000 from dual union all
select 10, 'fff', 40000 from dual union all
select 10, 'ddd', 40000 from dual union all
select 10, 'bbb', 50000 from dual union all
select 10, 'xxx', null from dual union all
select 10, 'ccc', 50000 from dual)
select empname, deptno, sal
, rank() over (partition by deptno order by sal nulls first) r
, dense_rank() over (partition by deptno order by sal nulls first) dr1
, dense_rank() over (partition by deptno order by sal nulls last) dr2
from q;
EMP DEPTNO SAL R DR1 DR2
--- ---------- ---------- ---------- ---------- ----------
xxx 10 1 1 4
rrr 10 10000 2 2 1
fff 10 40000 3 3 2
ddd 10 40000 3 3 2
ccc 10 50000 5 4 3
bbb 10 50000 5 4 3
mmm 11 5000 1 1 1
nnn 11 20000 2 2 2
kkk 12 30000 1 1 1

Here's a link to a good explanation and some examples.
On the Macintosh, place the cursor after either the opening or closing curly brace }
and use the keys: Shift + Command + P.
If you don't want to copy the array (say it is very large), you might want to create a wrapper List<Integer>
that can be used in a sort:
final int[] elements = {1, 2, 3, 4};
List<Integer> wrapper = new AbstractList<Integer>() {
@Override
public Integer get(int index) {
return elements[index];
}
@Override
public int size() {
return elements.length;
}
@Override
public Integer set(int index, Integer element) {
int v = elements[index];
elements[index] = element;
return v;
}
};
And now you can do a sort on this wrapper List using a custom comparator.
When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl
annotation on a create method in the ObjectFactory
class. Since you are creating the JAXBContext
on just the DocumentType
class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext
on the generated package name or ObjectFactory
class to ensure all the necessary metadata is processed.
Example solution:
JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();
You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.
I have perfect solution for this question try this code snippet.

To copy a sheet to a workbook called TARGET:
Sheets("xyz").Copy After:=Workbooks("TARGET.xlsx").Sheets("abc")
This will put the copied sheet xyz in the TARGET workbook after the sheet abc Obviously if you want to put the sheet in the TARGET workbook before a sheet, replace Before for After in the code.
To create a workbook called TARGET you would first need to add a new workbook and then save it to define the filename:
Application.Workbooks.Add (xlWBATWorksheet)
ActiveWorkbook.SaveAs ("TARGET")
However this may not be ideal for you as it will save the workbook in a default location e.g. My Documents.
Hopefully this will give you something to go on though.
To set volume to 0
AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);
To set volume to full
AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);
the volume can be adjusted by changing the index value between 0 and 20
With Tomcat 7, you can add the StuckThreadDetectionValve which will enable you to identify threads that are "stuck". You can set-up the valve in the Context element of the applications where you want to do detecting:
<Context ...>
...
<Valve
className="org.apache.catalina.valves.StuckThreadDetectionValve"
threshold="60" />
...
</Context>
This would write a WARN entry into the tomcat log for any thread that takes longer than 60 seconds, which would enable you to identify the applications and ban them because they are faulty.
Based on the source code you may be able to write your own valve that attempts to stop the thread, however this would have knock on effects on the thread pool and there is no reliable way of stopping a thread in Java without the cooperation of that thread...
You can try this
var lastPostDate = reader[3] == DBNull.Value ?

Try this hack :-) Gulp v3.x Hack for Async bug
I tried all of the "official" ways in the Readme, they didn't work for me but this did. You can also upgrade to gulp 4.x but I highly recommend you don't, it breaks so much stuff. You could use a real js promise, but hey, this is quick, dirty, simple :-) Essentially you use:
var wait = 0; // flag to signal thread that task is done
if(wait == 0) setTimeout(... // sleep and let nodejs schedule other threads

Hope this help!
You have to check the specific error within the javascript console (e.g. Ctrl + Shift + K in Firefox for Windows).
According to Steven Gliebe (2016), there are four common cases for this problem. If I may summarize it, as this:
After doing some code modification, please clear your browser cache as necessary.
In case there are other errors, you can check Google Maps API Error Codes Documentation page.
This is a good example based on domain driven design and explains why it is important to have separate domain layer.

Jin Yong - IE has an issue with polluting the global scope with object references to any DOM elements with a "name" or "id" attribute set on the "initial" page load.
Thus you may have issues due to your variable name.
Try this and see if it works.
var someOtherName="abc";
// ^^^^^^^^^^^^^
document.getElementById('msg').value = someOtherName;
document.getElementById('sp_100').checked = true;
There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value.
Keep in mind that in IE6/IE7 case doesn't matter for naming objects. IE believes that "foo" "Foo" and "FOO" are all the same object.
If your <option>
elements don't have value
attributes, then you can just use .val
:
$selectElement.val("text_you're_looking_for")
However, if your <option>
elements have value attributes, or might do in future, then this won't work, because whenever possible .val
will select an option by its value
attribute instead of by its text content. There's no built-in jQuery method that will select an option by its text content if the options have value
attributes, so we'll have to add one ourselves with a simple plugin:
/*
Source: https://stackoverflow.com/a/16887276/1709587
Usage instructions:
Call
jQuery('#mySelectElement').selectOptionWithText('target_text');
to select the <option> element from within #mySelectElement whose text content
is 'target_text' (or do nothing if no such <option> element exists).
*/
jQuery.fn.selectOptionWithText = function selectOptionWithText(targetText) {
return this.each(function () {
var $selectElement, $options, $targetOption;
$selectElement = jQuery(this);
$options = $selectElement.find('option');
$targetOption = $options.filter(
function () {return jQuery(this).text() == targetText}
);
// We use `.prop` if it's available (which it should be for any jQuery
// versions above and including 1.6), and fall back on `.attr` (which
// was used for changing DOM properties in pre-1.6) otherwise.
if ($targetOption.prop) {
$targetOption.prop('selected', true);
}
else {
$targetOption.attr('selected', 'true');
}
});
}
Just include this plugin somewhere after you add jQuery onto the page, and then do
jQuery('#someSelectElement').selectOptionWithText('Some Target Text');
to select options.
The plugin method uses filter
to pick out only the option
matching the targetText, and selects it using either .attr
or .prop
, depending upon jQuery version (see .prop() vs .attr() for explanation).

Use GA 'set' to ensure routes are picked up for Google realtime analytics. Otherwise subsequent calls to GA will not show in the realtime panel.
$scope.$on('$routeChangeSuccess', function() {
$window.ga('set', 'page', $location.url());
$window.ga('send', 'pageview');
});
Google strongly advises this approach generally instead of passing a 3rd param in 'send'. https://developers.google.com/analytics/devguides/collection/analyticsjs/single-page-applications
VisualVm does not come with Apple JDK. You can use VisualVM Mac Application bundle(dmg) as a separate application, to compensate for that.
If you're looking to compare times, and not the dates, you could just have a standard comparison date, or match to the date you're using, as in...
DateTime time = DateTime.Parse("6/22/2009 10:00AM");
DateTime compare = DateTime.Parse(time.ToShortDateString() + " 2:00PM");
bool greater = (time > compare);
There may be better ways to to this, but keeps your dates matching.

I solved this problem by deleting my gemset for my current project and recreating it and rerunning bundle install. I think I caused it by installing a newer version of mysql.
function loadpage (page_request, containerid)
{
var loading = document.getElementById ( "loading" ) ;
// when connecting to server
if ( page_request.readyState == 1 )
loading.style.visibility = "visible" ;
// when loaded successfully
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
{
document.getElementById(containerid).innerHTML=page_request.responseText ;
loading.style.visibility = "hidden" ;
}
}
The relevant section of the MySQL manual is here. I'd start by going through the debugging steps listed there.
Also, remember that localhost and 127.0.0.1 are not the same thing in this context:
localhost
, then a socket or pipe is used.127.0.0.1
, then the client is forced to use TCP/IP.So, for example, you can check if your database is listening for TCP connections vi netstat -nlp
. It seems likely that it IS listening for TCP connections because you say that mysql -h 127.0.0.1
works just fine. To check if you can connect to your database via sockets, use mysql -h localhost
.
If none of this helps, then you probably need to post more details about your MySQL config, exactly how you're instantiating the connection, etc.
Also i got this error if i had the comment in tn top level of template among with the actual root element.

tar -cjf site1.tar.bz2 -C /var/www/site1 .
adds the files as
tar -tf site1.tar.bz2
./style.css
./index.html
./page2.html
./page3.html
./images/img1.png
./images/img2.png
./subdir/index.html
If you really want
tar -tf site1.tar.bz2
style.css
index.html
page2.html
page3.html
images/img1.png
images/img2.png
subdir/index.html
You should either cd into the directory first or run
tar -cjf site1.tar.bz2 -C /var/www/site1 $(ls /var/www/site1)
Simple function, works with GET or POST. Plus you can assign a default value.
function GetPost($var,$default='') {
return isset($_GET[$var]) ? $_GET[$var] : (isset($_POST[$var]) ? $_POST[$var] : $default);
}
For checking for a time of day use:
TimeSpan start = new TimeSpan(10, 0, 0); //10 o'clock
TimeSpan end = new TimeSpan(12, 0, 0); //12 o'clock
TimeSpan now = DateTime.Now.TimeOfDay;
if ((now > start) && (now < end))
{
//match found
}
For absolute times use:
DateTime start = new DateTime(2009, 12, 9, 10, 0, 0)); //10 o'clock
DateTime end = new DateTime(2009, 12, 10, 12, 0, 0)); //12 o'clock
DateTime now = DateTime.Now;
if ((now > start) && (now < end))
{
//match found
}
There is a pretty library at http://256stuff.com/sources/md5/, with example of use. This is the simplest library for MD5.
There's a much faster way of doing this than using the merge.concat.apply() method listed in the top answer, and by faster I mean more than several orders of magnitude faster. This assumes your environment has access to the ES5 Array methods.
var array2d = [
["foo", "bar"],
["baz", "biz"]
];
merged = array2d.reduce(function(prev, next) {
return prev.concat(next);
});

Have tried several solutions here, nothing worked flawlessly; then Searched the web a bit more, to find GSAP at https://greensock.com/ (subject to license, but it's pretty permissive); once you reference the lib ...
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js"></script>
... you can go:
var el = document.getElementById('divID');
// create a timeline for this element in paused state
var tl = new TimelineMax({paused: true});
// create your tween of the timeline in a variable
tl
.set(el,{willChange:"transform"})
.to(el, 1, {transform:"rotate(60deg)", ease:Power1.easeInOut});
// store the tween timeline in the javascript DOM node
el.animation = tl;
//create the event handler
$(el).on("mouseenter",function(){
//this.style.willChange = 'transform';
this.animation.play();
}).on("mouseleave",function(){
//this.style.willChange = 'auto';
this.animation.reverse();
});
And it will work flawlessly.
You could simply do:
Select Req_ID, (avg(R1)+avg(R2)+avg(R3)+avg(R4)+avg(R5))/5 as Average
from Request
Group by Req_ID
Right?
I'm assuming that you may have multiple rows with the same Req_ID and in these cases you want to calculate the average across all columns and rows for those rows with the same Req_ID
Don't forget to call this.
style.setFillPattern(CellStyle.Align_Fill);
Parameter may differ according to your need. Maybe CellStyle.FINE_DOTS or so.
There are two obvious issues with the set literal syntax:
my_set = {'foo', 'bar', 'baz'}
It's not available before Python 2.7
There's no way to express an empty set using that syntax (using {}
creates an empty dict)
Those may or may not be important to you.
The section of the docs outlining this syntax is here.
You have to use RegExp object if your pattern is string
var xxx = "victoria";
var yyy = "i";
var rgxp = new RegExp(yyy, "g");
alert(xxx.match(rgxp).length);
If pattern is not dynamic string:
var xxx = "victoria";
var yyy = /i/g;
alert(xxx.match(yyy).length);

NumPy's arrays are more compact than Python lists -- a list of lists as you describe, in Python, would take at least 20 MB or so, while a NumPy 3D array with single-precision floats in the cells would fit in 4 MB. Access in reading and writing items is also faster with NumPy.
Maybe you don't care that much for just a million cells, but you definitely would for a billion cells -- neither approach would fit in a 32-bit architecture, but with 64-bit builds NumPy would get away with 4 GB or so, Python alone would need at least about 12 GB (lots of pointers which double in size) -- a much costlier piece of hardware!
The difference is mostly due to "indirectness" -- a Python list is an array of pointers to Python objects, at least 4 bytes per pointer plus 16 bytes for even the smallest Python object (4 for type pointer, 4 for reference count, 4 for value -- and the memory allocators rounds up to 16). A NumPy array is an array of uniform values -- single-precision numbers takes 4 bytes each, double-precision ones, 8 bytes. Less flexible, but you pay substantially for the flexibility of standard Python lists!
Actually python will reclaim the memory which is not in use anymore.This is called garbage collection which is automatic process in python. But still if you want to do it then you can delete it by del variable_name
. You can also do it by assigning the variable to None
a = 10
print a
del a
print a ## throws an error here because it's been deleted already.
The only way to truly reclaim memory from unreferenced Python objects is via the garbage collector. The del keyword simply unbinds a name from an object, but the object still needs to be garbage collected. You can force garbage collector to run using the gc module, but this is almost certainly a premature optimization but it has its own risks. Using del
has no real effect, since those names would have been deleted as they went out of scope anyway.
Just in addition to the above answers, for the question where and when you should call getLocationOnScreen
?
For any information that is related to the view
, will be available only after the view has been laid out(created) on the screen. So to get the location put your code inside view.post(Runnable)
which is called after view
has been laid out, like this:
view.post(new Runnable() {
@Override
public void run() {
// This code will run when view created and rendered on screen
// So as the answer to this question, you can put the code here
int[] location = new int[2];
myView.getLocationOnScreen(location);
int x = location[0];
int y = location[1];
}
});
SQL tables have no implicit ordering, the order has to come from the data. Perhaps you should add a field to your table (e.g. an int counter) and re-import the data.
However that will only give the order of the import and not the data. If your data has no ordering you have to find out how to add it.
EDIT: you say
...to make sure it imported everything.
What's wrong with using row count?
My DBA asked me when I asked about the best way to store GUIDs for my objects why I needed to store 16 bytes when I could do the same thing in 4 bytes with an Integer. Since he put that challenge out there to me I thought now was a good time to mention it. That being said...
You can store a guid as a CHAR(16) binary if you want to make the most optimal use of storage space.
I have found following way to fix this issue... I hope this can help you.
json_encode($data,JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES);
yes, simply use colspan.
The short answer: the setting needs to be setup when the connection to the MySQL server is established. For example, if using MYSQLi / PHP, it will look something like this:
$ myConn = mysqli_init();
$ myConn->options(MYSQLI_INIT_COMMAND, 'SET SESSION group_concat_max_len = 1000000');
Therefore, if you are using a home-brewed framework, well, you need to look for the place in the code when the connection is establish and provide a sensible value.
I am still using Codeigniter 3 on 2020, so in this framework, the code to add is in the application/system/database/drivers/mysqli/mysqli_driver.php, the function is named db_connect();
public function db_connect($persistent = FALSE)
{
// Do we have a socket path?
if ($this->hostname[0] === '/')
{
$hostname = NULL;
$port = NULL;
$socket = $this->hostname;
}
else
{
$hostname = ($persistent === TRUE)
? 'p:'.$this->hostname : $this->hostname;
$port = empty($this->port) ? NULL : $this->port;
$socket = NULL;
}
$client_flags = ($this->compress === TRUE) ? MYSQLI_CLIENT_COMPRESS : 0;
$this->_mysqli = mysqli_init();
$this->_mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 10);
$this->_mysqli->options(MYSQLI_INIT_COMMAND, 'SET SESSION group_concat_max_len = 1000000');
...
}
you can also refactor your solution removing the first loop:
Set<Integer> set = new HashSet<Integer>();
Collection<Integer> removeCandidates = new LinkedList<Integer>(set);
for(Integer element : set)
if(element % 2 == 0)
removeCandidates.add(element);
set.removeAll(removeCandidates);
abc(?!def) will match abc not followed by def. So it'll match abce, abc, abck, etc. what if I want neither def nor xyz will it be abc(?!(def)(xyz)) ???
I had the same question and found a solution:
abc(?:(?!def))(?:(?!xyz))
These non-counting groups are combined by "AND", so it this should do the trick. Hope it helps.
Another technique to consider if you want to compare a file to the last commit which is more pedantic:
git diff master myfile.txt
The advantage with this technique is you can also compare to the penultimate commit with:
git diff master^ myfile.txt
and the one before that:
git diff master^^ myfile.txt
Also you can substitute '~' for the caret '^' character and 'you branch name' for 'master' if you are not on the master branch.

I ran into this issue in Eclipse on Mac OS X v10.9 (Mavericks). I tried many answers on Stack Overflow ... finally, after a full day I *installed a fresh version of the Android SDK (and updated Eclipse, menu Project ? Properties ? Android to use the new path)*.
I had to get SDK updates, but only pulling down those updates I thought were necessary, avoiding APIs I were not working with (like Wear and TV) .. and that did the trick. Apparently, it seems I had corrupted my SDK somewhere along the way.
BTW .. I did see the error re-surface with one project in my workspace, but it seemed related to an import of appcompat-7, which I was not using. After rm-ing that project, so far haven't seen the issue resurface.
Use:
import matplotlib.pyplot as plt
plt.gcf().subplots_adjust(bottom=0.15)
to make room for the label.
Edit:
Since i gave the answer, matplotlib
has added the tight_layout()
function.
So i suggest to use it:
plt.tight_layout()
should make room for the xlabel.
I tried to execute httpd.exe in cmd and got error that there's syntax error in httpd-vhosts.conf. I checked file and found what's wrong and it's working fine now.
So, if you are facing this error then it may be because of httpd-vhosts or any other file.
Try to execute the program via cmd and you will get the error details and the line where is syntax error.
Best of luck
If your goal is to have
str = "Hello\nWorld";
and output what it contains in string literal form, you can use JSON.stringify
:
console.log(JSON.stringify(str)); // ""Hello\nWorld""
const str = "Hello\nWorld";_x000D_
const json = JSON.stringify(str);_x000D_
console.log(json); // ""Hello\nWorld""_x000D_
for (let i = 0; i < json.length; ++i) {_x000D_
console.log(`${i}: ${json.charAt(i)}`);_x000D_
}
_x000D_
.as-console-wrapper {_x000D_
max-height: 100% !important;_x000D_
}
_x000D_
console.log
adds the outer quotes (at least in Chrome's implementation), but the content within them is a string literal (yes, that's somewhat confusing).
JSON.stringify
takes what you give it (in this case, a string) and returns a string containing valid JSON for that value. So for the above, it returns an opening quote ("
), the word Hello
, a backslash (\
), the letter n
, the word World
, and the closing quote ("
). The linefeed in the string is escaped in the output as a \
and an n
because that's how you encode a linefeed in JSON. Other escape sequences are similarly encoded.
Using stage-2 preset before react preset helped me:

You cannot use iOS APIs alone to capture the phone number (even in a private app with private APIs), as all known methods of doing this have been patched and blocked as of iOS 11. Even if a new exploit is found, Apple has made clear that they will reject any apps from the app store for using private APIs to do this. See @Dylan's answer for details.
However, there is a legal way to capture the phone number without any user data entry. This is similar to what Snapchat does, but easier, as it does not require the user to type in their own phone number.
The idea is to have the app programmatically send a SMS message to a server with the app’s unique installation code. The app can then query the same server to see if it has recently received a SMS message from a device with this unique app installation code. If it has, it can read the phone number that sent it. Here’s a demo video showing the process. As you can see, it works like a charm!

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.
If you have accidentally removed DLL file from php/ext
folder, just add it back (get the copy from XAMPP zip archive - its downloadable).
If you have deleted the accompanying INI configuration line from php.ini
file, add it back as well:
extension=php_mbstring.dll
Also, ensure to restart your webserver (Apache) using XAMPP control panel.

I wanted to verify myself that 'SET NOCOUNT ON' does not save a network packet nor a roundtrip
I used a test SQLServer 2017 on another host (I used a VM)
create table ttable1 (n int);
insert into ttable1 values (1),(2),(3),(4),(5),(6),(7)
go
create procedure procNoCount
as
begin
set nocount on
update ttable1 set n=10-n
end
create procedure procNormal
as
begin
update ttable1 set n=10-n
end
Then I traced packets on port 1433 with the tool 'Wireshark':
'capture filter' button -> 'port 1433'
exec procNoCount
this is the response packet:

On line 40 I can see '07' which is the number of 'row(s) affected'. It is included in the response packet. No extra packet.
It has however 13 extra bytes which could be saved, but probably not more worth it than reducing column names (e.g. 'ManagingDepartment' to 'MD')
So I see no reason to use it for performance
BUT As others mentioned it can break ADO.NET and I also stumbled on an issue using python: MSSQL2008 - Pyodbc - Previous SQL was not a query
So probably a good habit still...

Just to add some further thoughts which may help others with irregular domain type problems. For a situation where the user has three vectors/lists, x,y,z representing a 2D solution where z is to be plotted on a rectangular grid as a surface, the 'plot_trisurf()' comments by ArtifixR are applicable. A similar example but with non rectangular domain is:
import matplotlib.pyplot as plt
from matplotlib import cm
from mpl_toolkits.mplot3d import Axes3D
# problem parameters
nu = 50; nv = 50
u = np.linspace(0, 2*np.pi, nu,)
v = np.linspace(0, np.pi, nv,)
xx = np.zeros((nu,nv),dtype='d')
yy = np.zeros((nu,nv),dtype='d')
zz = np.zeros((nu,nv),dtype='d')
# populate x,y,z arrays
for i in range(nu):
for j in range(nv):
xx[i,j] = np.sin(v[j])*np.cos(u[i])
yy[i,j] = np.sin(v[j])*np.sin(u[i])
zz[i,j] = np.exp(-4*(xx[i,j]**2 + yy[i,j]**2)) # bell curve
# convert arrays to vectors
x = xx.flatten()
y = yy.flatten()
z = zz.flatten()
# Plot solution surface
fig = plt.figure(figsize=(6,6))
ax = Axes3D(fig)
ax.plot_trisurf(x, y, z, cmap=cm.jet, linewidth=0,
antialiased=False)
ax.set_title(r'trisurf example',fontsize=16, color='k')
ax.view_init(60, 35)
fig.tight_layout()
plt.show()
The above code produces:
However, this may not solve all problems, particular where the problem is defined on an irregular domain. Also, in the case where the domain has one or more concave areas, the delaunay triangulation may result in generating spurious triangles exterior to the domain. In such cases, these rogue triangles have to be removed from the triangulation in order to achieve the correct surface representation. For these situations, the user may have to explicitly include the delaunay triangulation calculation so that these triangles can be removed programmatically. Under these circumstances, the following code could replace the previous plot code:
import matplotlib.tri as mtri
import scipy.spatial
# plot final solution
pts = np.vstack([x, y]).T
tess = scipy.spatial.Delaunay(pts) # tessilation
# Create the matplotlib Triangulation object
xx = tess.points[:, 0]
yy = tess.points[:, 1]
tri = tess.vertices # or tess.simplices depending on scipy version
#############################################################
# NOTE: If 2D domain has concave properties one has to
# remove delaunay triangles that are exterior to the domain.
# This operation is problem specific!
# For simple situations create a polygon of the
# domain from boundary nodes and identify triangles
# in 'tri' outside the polygon. Then delete them from
# 'tri'.
# <ADD THE CODE HERE>
#############################################################
triDat = mtri.Triangulation(x=pts[:, 0], y=pts[:, 1], triangles=tri)
# Plot solution surface
fig = plt.figure(figsize=(6,6))
ax = fig.gca(projection='3d')
ax.plot_trisurf(triDat, z, linewidth=0, edgecolor='none',
antialiased=False, cmap=cm.jet)
ax.set_title(r'trisurf with delaunay triangulation',
fontsize=16, color='k')
plt.show()
Example plots are given below illustrating solution 1) with spurious triangles, and 2) where they have been removed:
I hope the above may be of help to people with concavity situations in the solution data.
The definition of the perfmon counters has been broken since the beginning and for some reason appears to be too hard to correct.
A good overview of Windows memory management is available in the video "Mysteries of Memory Management Revealed" on MSDN: It covers more topics than needed to track memory leaks (eg working set management) but gives enough detail in the relevant topics.
To give you a hint of the problem with the perfmon counter descriptions, here is the inside story about private bytes from "Private Bytes Performance Counter -- Beware!" on MSDN:
Q: When is a Private Byte not a Private Byte?
A: When it isn't resident.
The Private Bytes counter reports the commit charge of the process. That is to say, the amount of space that has been allocated in the swap file to hold the contents of the private memory in the event that it is swapped out. Note: I'm avoiding the word "reserved" because of possible confusion with virtual memory in the reserved state which is not committed.
From "Performance Planning" on MSDN:
3.3 Private Bytes
3.3.1 Description
Private memory, is defined as memory allocated for a process which cannot be shared by other processes. This memory is more expensive than shared memory when multiple such processes execute on a machine. Private memory in (traditional) unmanaged dlls usually constitutes of C++ statics and is of the order of 5% of the total working set of the dll.
Welcome to Microsoft Marketing Speak hell. With the 2012 release of SQL Server, the BIDS, Business Intelligence Designer Studio, plugin for Visual Studio was renamed to SSDT, SQL Server Data Tools. SSDT is available for 2010 and 2012. The problem is, there are two different products called SSDT.
There is SSDT which replaces the database designer thing which was called Data Dude in VS 2008 and in 2010 became database projects. That a free install and if you snag the web installer, that's what you get when you install SSDT. It puts the correct project templates and such into Visual Studio.
There's also the SSDT which is the "BIDS" replacement for developing SSIS, SSRS and SSAS stuff. As of March 2013, it is now available for the 2012 release of Visual Studio. The download is labeled SSDTBI_VS2012_X86.msi Perhaps that's a signal on how the product is going to be referred to in marketing materials. Download links are
None the less, we have Business Intelligence projects available to us in Visual Studio 2012. And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals
Try .replace(/ /g,"_");
Edit: or .split(' ').join('_')
if you have an aversion to REs
Edit: John Resig said:
If you're searching and replacing through a string with a static search and a static replace it's faster to perform the action with .split("match").join("replace") - which seems counter-intuitive but it manages to work that way in most modern browsers. (There are changes going in place to grossly improve the performance of .replace(/match/g, "replace") in the next version of Firefox - so the previous statement won't be the case for long.)
Replace all non-digit with blank: the remaining string contains only digits.
Integer.parseInt(s.replaceAll("[\\D]", ""))
This will also remove non-digits inbetween digits, so "x1x1x"
becomes 11
.
If you need to confirm that the string consists of a sequence of digits (at least one) possibly followed a letter, then use this:
s.matches("[\\d]+[A-Za-z]?")
dynamically build list of objects
var listOfObjects = [];
var a = ["car", "bike", "scooter"];
a.forEach(function(entry) {
var singleObj = {};
singleObj['type'] = 'vehicle';
singleObj['value'] = entry;
listOfObjects.push(singleObj);
});

Take a look at debug_toolbar, it's very useful for debugging.

I agree with @MihaiIorga in the comments – use the PHPMailer script. You sound like you're rejecting it because you want the easier option. Trust me, PHPMailer is the easier option by a very large margin compared to trying to do it yourself with PHP's built-in mail()
function. PHP's mail()
function really isn't very good.
To use PHPMailer:
require_once('path/to/file/class.phpmailer.php');
Now, sending emails with attachments goes from being insanely difficult to incredibly easy:
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
$email = new PHPMailer();
$email->SetFrom('[email protected]', 'Your Name'); //Name is optional
$email->Subject = 'Message Subject';
$email->Body = $bodytext;
$email->AddAddress( '[email protected]' );
$file_to_attach = 'PATH_OF_YOUR_FILE_HERE';
$email->AddAttachment( $file_to_attach , 'NameOfFile.pdf' );
return $email->Send();
It's just that one line $email->AddAttachment();
-- you couldn't ask for any easier.
If you do it with PHP's mail()
function, you'll be writing stacks of code, and you'll probably have lots of really difficult to find bugs.
This is a great example of using the wrong tool for the job. Regular expressions do not handle arbitrarily nested sub-matches very well. What you should do instead is use a real lexer and parser (a grammar for C++ should be easy to find) and look for unexpectedly empty loop bodies.

//Abstract factory - Provides interface to create factory of related products
interface PizzaIngredientsFactory{
public Dough createDough(); //Will return you family of Dough
public Clam createClam(); //Will return you family of Clam
public Sauce createSauce(); //Will return you family of Sauce
}
class NYPizzaIngredientsFactory implements PizzaIngredientsFactory{
@Override
public Dough createDough(){
//create the concrete dough instance that NY uses
return doughInstance;
}
//override other methods
}
The text book definitions are already provided by other answers. I thought I would provide an example of it too.
So here the PizzaIngredientsFactory
is an abstract factory as it provides methods to create family of related products.
Note that each method in the Abstract factory is an Factory method in itself. Like createDough()
is in itself a factory method whose concrete implementations will be provided by subclasses like NYPizzaIngredientsFactory
. So using this each different location can create instances of concrete ingredients that belong to their location.
Provides instance of concrete implementation
In the example:
- createDough()
- provides concrete implementation for dough. So this is a factory method
Provides interface to create family of related objects
In the example:
- PizzaIngredientsFactory
is an abstract factory as it allows to create a related set of objects like Dough
, Clams
, Sauce
. For creating each family of objects it provides a factory method.

In regards to this:
"in my task I have to change the whole array (2 dimensions"
Just use a "jagged" array (ie an array of arrays of values). Then you can change the dimensions as you wish. You can have a 1-D array of variants, and the variants can contain arrays.
A bit more work perhaps, but a solution.
I would expect everything below /data
to belong to "internal storage". You should, however, be able to write to /sdcard
.
I generally try to avoid expressions with ng-show and ng-hide as they were designed as booleans, not conditionals. If I need both conditional and boolean logic, I prefer to put in the conditional logic using ng-if as the first check, then add in an additional check for the boolean logic with ng-show and ng-hide
Howerver, if you want to use a conditional for ng-show or ng-hide, here is a link with some examples: Conditional Display using ng-if, ng-show, ng-hide, ng-include, ng-switch

One package that is very likely to be installed on a system already is python-lxml
. If so, this is possible without installing any extra package:
python -c "from lxml.etree import parse; from sys import stdin; print('\n'.join(parse(stdin).xpath('//element/@attribute')))"
Try using the full type name that includes the assembly info, for example:
string typeName = @"MyCompany.MyApp.MyDomain.MyClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null";
Type myClassType = Type.GetType(typeName);
I had the same situation when I was using only the the namesspace.classname to get the type of a class in a different assembly and it would not work. Only worked when I included the assembly info in my type string as shown above.
Yes, a struct
is identical to a class
except for the default access level (member-wise and inheritance-wise). (and the extra meaning class
carries when used with a template)
Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.
struct foo {
int bar;
foo() : bar(3) {} //look, a constructor
int getBar()
{
return bar;
}
};
foo f;
int y = f.getBar(); // y is 3

Probably the new PyCharm from the makers of IntelliJ and ReSharper.
UPDATED: assuming C# 6, the chances are that your case can be expressed as an exception filter. This is the ideal approach from a performance perspective assuming your requirement can be expressed in terms of it, e.g.:
try
{
}
catch ( Web2PDFException ex ) when ( ex.Code == 52 )
{
}
Assuming C# < 6, the most efficient is to catch a specific Exception
type and do handling based on that. Any catch-all handling can be done separately
try
{
}
catch ( Web2PDFException ex )
{
}
or
try
{
}
catch ( Web2PDFException ex )
{
}
catch ( Exception ex )
{
}
or (if you need to write a general handler - which is generally a bad idea, but if you're sure it's best for you, you're sure):
if( err is Web2PDFException)
{
}
or (in certain cases if you need to do some more complex type hierarchy stuff that cant be expressed with is
)
if( err.GetType().IsAssignableFrom(typeof(Web2PDFException)))
{
}
or switch to VB.NET or F# and use is
or Type.IsAssignableFrom
in Exception Filters
I think this should be:

Ok, so I've tried using the Xampp Control Panel and choosing from the Config menu to start MySQL did not work. Instead go to C:\xampp\mysql and run a file entitled mysql_installservice and MySQL will automatically run as a Windows service.
In many linux release, you can find complier.h in /usr/linux/ , you can include it for use simply. And another opinion, unlikely() is more useful rather than likely(), because
if ( likely( ... ) ) {
doSomething();
}
it can be optimized as well in many compiler.
And by the way, if you want to observe the detail behavior of the code, you can do simply as follow:
gcc -c test.c objdump -d test.o > obj.s
Then, open obj.s, you can find the answer.
PHP's var_export() usually shows a serialized version of the object that can be exec()'d to re-create the object. The closest thing to that in Python is repr()
"For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval() [...]"
Simple Add this Code
var status = "play"; // Declare global variable
if (status == 'pause') {
status='play';
} else {
status = 'pause';
}
$("#audio").trigger(status);

Sequence Containers
vector
: The functions insert
, emplace_back
, emplace
, push_back
cause reallocation if the new size is greater than the old capacity. Reallocation invalidates all the references, pointers, and iterators referring to the elements in the sequence. If no reallocation
happens, all the iterators and references before the insertion point remain valid. [26.3.11.5/1]
With respect to the reserve
function, reallocation invalidates all the references, pointers, and iterators referring to the elements in the sequence. No reallocation shall take place during insertions that happen after a call to reserve()
until the time when an insertion would make the size of the vector greater than the value of capacity()
. [26.3.11.3/6]
deque
: An insertion in the middle of the deque invalidates all the iterators and references to elements of the deque. An insertion at either end of the deque invalidates all the iterators to the deque, but has no effect on the validity of references to elements of the deque. [26.3.8.4/1]
list
: Does not affect the validity of iterators and references. If an exception is thrown there are no effects. [26.3.10.4/1].
The insert
, emplace_front
, emplace_back
, emplace
, push_front
, push_back
functions are covered under this rule.
forward_list
: None of the overloads of insert_after
shall affect the validity of iterators and references [26.3.9.5/1]
array
: As a rule, iterators to an array are never invalidated throughout the lifetime of the array. One should take note, however, that during swap, the iterator will continue to point to the same array element, and will thus change its value.
Associative Containers
All Associative Containers
: The insert
and emplace
members shall not affect the validity of iterators and references to the container [26.2.6/9]Unordered Associative Containers
All Unordered Associative Containers
: Rehashing invalidates iterators, changes ordering between elements, and changes which buckets elements appear in, but does not invalidate pointers or references to elements. [26.2.7/9]
The insert
and emplace
members shall not affect the validity of references to container elements, but may invalidate all iterators to the container. [26.2.7/14]
The insert
and emplace
members shall not affect the validity of iterators if (N+n) <= z * B
, where N
is the number of elements in the container prior to the insert operation, n
is the number of elements inserted, B
is the container’s bucket count, and z
is the container’s maximum load factor. [26.2.7/15]
All Unordered Associative Containers
: In case of a merge operation (e.g., a.merge(a2)
), iterators referring to the transferred elements and all iterators referring to a
will be invalidated, but iterators to elements remaining in a2
will remain valid. (Table 91 — Unordered associative container requirements)

deque
: An erase operation that erases the last element of a deque
invalidates only the past-the-end iterator and all iterators and references to the erased elements. An erase operation that erases the first element of a deque
but not the last element invalidates only iterators and references to the erased elements. An erase operation that erases neither the first element nor the last element of a deque
invalidates the past-the-end iterator and all iterators and references to all the elements of the deque
.
[ Note: pop_front

member functions: Erases all the elements in the list referred by a list iterator i
for which the following conditions hold: *i == value

forward_list
: erase_after
shall invalidate only iterators and references to the erased elements. [26.3.9.5/1].
remove

All Sequence Containers
: clear
invalidates all references, pointers, and iterators referring to the elements of a and may invalidate the past-the-end iterator (Table 87 — Sequence container requirements). But for forward_list
, clear
does not invalidate past-the-end iterators. [26.3.9.5/32]
All Sequence Containers

: inherited from underlying containerpriority_queue
: inherited from underlying containerGeneral container requirements relating to iterator invalidation:
Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [26.2.1/12]
no swap()
function invalidates any references, pointers, or iterators referring to the elements of the containers being swapped. [ Note: The end() iterator does not refer to any element, so it may be invalidated. —end note ] [26.2.1/(11.6)]
As examples of the above requirements:
transform

and so on...
Ok uninstall the app, but we admit that the data not must be lost? This can be resolve, upgrading versionCode and versionName and try the application in "Release" mode.
For example, this is important when we want to try the migration of our Database. We can compare the our application on play store with actual application not release yet.
The reason this is happening is because initializing an array does not initialize each element in that array. You need to first set houses[0] = new GameObject()
and then it will work.

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.
That is neither a good idea in terms of peformance nor in terms of fail-safety.
There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:
In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.
Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.
So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.
So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.
If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).
Conclusion:
using-statement
to dispose and close(in case of Connections) implicitelyThat's true not only for Connections(although most noticable). Every object implementing IDisposable
should be disposed(simplest by using-statement
), all the more in the System.Data.SqlClient
namespace.
All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.
Edit: Here's a possible implementation of your retrievePromotion
-method:
public Promotion retrievePromotion(int promotionID)
{
Promotion promo = null;
var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
using (SqlConnection connection = new SqlConnection(connectionString))
{
var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
using (var da = new SqlDataAdapter(queryString, connection))
{
// you could also use a SqlDataReader instead
// note that a DataTable does not need to be disposed since it does not implement IDisposable
var tblPromotion = new DataTable();
// avoid SQL-Injection
da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
try
{
connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise
da.Fill(tblPromotion);
if (tblPromotion.Rows.Count != 0)
{
var promoRow = tblPromotion.Rows[0];
promo = new Promotion()
{
promotionID = promotionID,
promotionTitle = promoRow.Field<String>("PromotionTitle"),
promotionUrl = promoRow.Field<String>("PromotionURL")
};
}
}
catch (Exception ex)
{
// log this exception or throw it up the StackTrace
// we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
throw;
}
}
}
return promo;
}
For new projects please refrain from using request, since now the project is in maitainance mode, and will eventually be deprecated
https://github.com/request/request/issues/3142
Instead i would recommend Axios, the library is in line with Node latest standards, and there are some available plugins to enhance it, enabling mock server responses, automatic retries and other features.
https://github.com/axios/axios
const axios = require('axios');
// Make a request for a user with a given ID
axios.get('/user?ID=12345')
.then(function (response) {
// handle success
console.log(response);
})
.catch(function (error) {
// handle error
console.log(error);
})
.then(function () {
// always executed
});
Or using async / await:
try{
const response = await axios.get('/user?ID=12345');
console.log(response)
} catch(axiosErr){
console.log(axiosErr)
}
I usually use REQUEST, its a simplified but powerful HTTP client for Node.js
https://github.com/request/request
Its on NPM
npm install request
Here is a usage sample:
var request = require('request');
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Show the HTML for the Google homepage.
}
})
Some modern browsers (Firefox, Safari, and Opera, but not Chrome) support the special "back/forward" cache (I'll call it bfcache, which is a term invented by Mozilla), involved when the user navigates Back. Unlike the regular (HTTP) cache, it captures the complete state of the page (including the state of JS, DOM). This allows it to re-load the page quicker and exactly as the user left it.
The load
event is not supposed to fire when the page is loaded from this bfcache. For example, if you created your UI in the "load" handler, and the "load" event was fired once on the initial load, and the second time when the page was re-loaded from the bfcache, the page would end up with duplicate UI elements.
This is also why adding the "unload" handler stops the page from being stored in the bfcache (thus making it slower to navigate back to) -- the unload handler could perform clean-up tasks, which could leave the page in unworkable state.
For pages that need to know when they're being navigated away/back to, Firefox 1.5+ and the version of Safari with the fix for bug 28758 support special events called "pageshow" and "pagehide".

You can use np.where()
to set values based on a specified condition:
#df
c1 c2 c3
0 4 2 1
1 8 7 9
2 1 5 8
3 3 3 5
4 3 6 8
Now change values (or set) in column ['c2']
based on your condition.
df['c2'] = np.where(df.c1 == 8,'X', df.c3)
c1 c3 c4
0 4 1 1
1 8 9 X
2 1 8 8
3 3 5 5
4 3 8 8
The number is held in an int[]
- the maximum size of an array is Integer.MAX_VALUE
. So the maximum BigInteger probably is (2 ^ 32) ^ Integer.MAX_VALUE
.
Admittedly, this is implementation dependent, not part of the specification.
In Java 8, some information was added to the BigInteger javadoc, giving a minimum supported range and the actual limit of the current implementation:
BigInteger
must support values in the range-2
Integer.MAX_VALUE
(exclusive) to+2
Integer.MAX_VALUE
(exclusive) and may support values outside of that range.Implementation note:
BigInteger
constructors and operations throwArithmeticException
when the result is out of the supported range of-2
Integer.MAX_VALUE
(exclusive) to+2
Integer.MAX_VALUE
(exclusive).
Different file name which posted as "recfile" at <input type="file" name='recfile' placeholder="Select file"/>
and received as "file" at upload.single('file')
Solution : make sure both sent and received file are similar upload.single('recfile')
Since the page you load inside the iframe can execute the "break out" code with a setInterval, onbeforeunload might not be that practical, since it could flud the user with 'Are you sure you want to leave?' dialogs.
There is also the iframe security attribute which only works on IE & Opera
:(

While only a few lines are required to plot multiple/overlapping histograms in ggplot2, the results are't always satisfactory. There needs to be proper use of borders and coloring to ensure the eye can differentiate between histograms.
The following functions balance border colors, opacities, and superimposed density plots to enable the viewer to differentiate among distributions.
Single histogram:
plot_histogram <- function(df, feature) {
plt <- ggplot(df, aes(x=eval(parse(text=feature)))) +
geom_histogram(aes(y = ..density..), alpha=0.7, fill="#33AADE", color="black") +
geom_density(alpha=0.3, fill="red") +
geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
labs(x=feature, y = "Density")
print(plt)
}
Multiple histogram:
plot_multi_histogram <- function(df, feature, label_column) {
plt <- ggplot(df, aes(x=eval(parse(text=feature)), fill=eval(parse(text=label_column)))) +
geom_histogram(alpha=0.7, position="identity", aes(y = ..density..), color="black") +
geom_density(alpha=0.7) +
geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
labs(x=feature, y = "Density")
plt + guides(fill=guide_legend(title=label_column))
}
Usage:
Simply pass your data frame into the above functions along with desired arguments:
plot_histogram(iris, 'Sepal.Width')
plot_multi_histogram(iris, 'Sepal.Width', 'Species')
The extra parameter in plot_multi_histogram is the name of the column containing the category labels.
We can see this more dramatically by creating a dataframe with many different distribution means:
a <-data.frame(n=rnorm(1000, mean = 1), category=rep('A', 1000))
b <-data.frame(n=rnorm(1000, mean = 2), category=rep('B', 1000))
c <-data.frame(n=rnorm(1000, mean = 3), category=rep('C', 1000))
d <-data.frame(n=rnorm(1000, mean = 4), category=rep('D', 1000))
e <-data.frame(n=rnorm(1000, mean = 5), category=rep('E', 1000))
f <-data.frame(n=rnorm(1000, mean = 6), category=rep('F', 1000))
many_distros <- do.call('rbind', list(a,b,c,d,e,f))
Passing data frame in as before (and widening chart using options):
options(repr.plot.width = 20, repr.plot.height = 8)
plot_multi_histogram(many_distros, 'n', 'category')
No need to apply anything. Just add this code at the end of variable to which date is assigned. For example
@todaydate = "2011-05-19 10:30:14"
@todaytime.to_time.strftime('%a %b %d %H:%M:%S %Z %Y')
You will get proper format as you like. You can check this at Rails Console
Loading development environment (Rails 3.0.4)
ruby-1.9.2-p136 :001 > todaytime = "2011-05-19 10:30:14"
=> "2011-05-19 10:30:14"
ruby-1.9.2-p136 :002 > todaytime
=> "2011-05-19 10:30:14"
ruby-1.9.2-p136 :003 > todaytime.to_time
=> 2011-05-19 10:30:14 UTC
ruby-1.9.2-p136 :008 > todaytime.to_time.strftime('%a %b %d %H:%M:%S %Z %Y')
=> "Thu May 19 10:30:14 UTC 2011"
Try 'date_format' gem to show date in different format.

Remember that the "folders/groups" you make in xcode, those which are yellowish are not reflected as real folders in your iPhone app. They are just there to structure your XCode project. You can nest as many yellow group as you want and they still only serve the purpose of organizing code in XCode.
Make a folder outside of XCode then drag it over, and select "Create folder references for any added folders" instead of "Create groups for any added folders" in the popup.
Try this, example, the required property in below input tag will ensure that the name field should be submitted empty.

Please take care that the epoch time is in second and Date object accepts Long value which is in milliseconds. Hence you would have to multiply epoch value with 1000 to use it as long value . Like below :-
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
sdf.setTimeZone(TimeZone.getTimeZone(timeZone));
Long dateLong=Long.parseLong(sdf.format(epoch*1000));
I thought my simple "all possible combination generator" might help someone, i think its a really good example for building something bigger and better
you can change N (characters) to any you like by just removing/adding from string array (you can change it to int as well). Current amount of characters is 36
you can also change K (size of the generated combinations) by just adding more loops, for each element, there must be one extra loop. Current size is 4
#include<iostream>
using namespace std;
int main() {
string num[] = {"0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z" };
for (int i1 = 0; i1 < sizeof(num)/sizeof(string); i1++) {
for (int i2 = 0; i2 < sizeof(num)/sizeof(string); i2++) {
for (int i3 = 0; i3 < sizeof(num)/sizeof(string); i3++) {
for (int i4 = 0; i4 < sizeof(num)/sizeof(string); i4++) {
cout << num[i1] << num[i2] << num[i3] << num[i4] << endl;
}
}
}
}}
Result
0: A A A
1: B A A
2: C A A
3: A B A
4: B B A
5: C B A
6: A C A
7: B C A
8: C C A
9: A A B
...
just keep in mind that the amount of combinations can be ridicules.
--UPDATE--
a better way to generate all possible combinations would be with this code, which can be easily adjusted and configured in the "variables" section of the code.
#include<iostream>
#include<math.h>
int main() {
//VARIABLES
char chars[] = { 'A', 'B', 'C' };
int password[4]{0};
//SIZES OF VERIABLES
int chars_length = sizeof(chars) / sizeof(char);
int password_length = sizeof(password) / sizeof(int);
//CYCKLE TROUGH ALL OF THE COMBINATIONS
for (int i = 0; i < pow(chars_length, password_length); i++){
//CYCKLE TROUGH ALL OF THE VERIABLES IN ARRAY
for (int i2 = 0; i2 < password_length; i2++) {
//IF VERIABLE IN "PASSWORD" ARRAY IS THE LAST VERIABLE IN CHAR "CHARS" ARRRAY
if (password[i2] == chars_length) {
//THEN INCREMENT THE NEXT VERIABLE IN "PASSWORD" ARRAY
password[i2 + 1]++;
//AND RESET THE VERIABLE BACK TO ZERO
password[i2] = 0;
}}
//PRINT OUT FIRST COMBINATION
std::cout << i << ": ";
for (int i2 = 0; i2 < password_length; i2++) {
std::cout << chars[password[i2]] << " ";
}
std::cout << "\n";
//INCREMENT THE FIRST VERIABLE IN ARRAY
password[0]++;
}}
If you're having troubles specifying the SDK target to Google APIs instead of the base Platform SDK just change the compileSdkVersion 19
to compileSdkVersion "Google Inc.:Google APIs:19"
this example, I am assuming that all your image files begin with "IMG" and you want to replace "IMG" with "VACATION"
solution : first identified all jpg files and then replace keyword
find . -name '*jpg' -exec bash -c 'echo mv $0 ${0/IMG/VACATION}' {} \;
SELECT SUBSTRING('aaaaa$bbbbb$ccccc',instr('aaaaa$bbbbb$ccccc','$',1,1)+1, instr('aaaaa$bbbbb$ccccc','$',1,2)-1) -instr('aaaaa$bbbbb$ccccc','$',1,1)) as My_String
It really also depends on how you name your variable.
When people are asking "which is better practice" - this implicitly implies that both are correct, so it's just a matter of which is easier to read and maintain.
If you name your variable "status" (which is the case in your example code), I would much prefer to see
if(status == false) // if status is false
On the other hand, if you had named your variable isXXX (e.g. isReadableCode), then the former is more readable. consider:
if(!isReadable) { // if not readable
System.out.println("I'm having a headache reading your code");
}
CDATA is a sequence of characters from the document character set and may include character entities. User agents should interpret attribute values as follows: Replace character entities with characters,
Ignore line feeds,
Replace each carriage return or tab with a single space.
I really don't see the right answer to this anywhere
class MyClass(dict):
def __init__(self, a_property):
self[a_property] = a_property
All you are really having to do is define your own __init__
- that really is all that there is too it.
Another example (little more complex):
class MyClass(dict):
def __init__(self, planet):
self[planet] = planet
info = self.do_something_that_returns_a_dict()
if info:
for k, v in info.items():
self[k] = v
def do_something_that_returns_a_dict(self):
return {"mercury": "venus", "mars": "jupiter"}
This last example is handy when you want to embed some kind of logic.
Anyway... in short class GiveYourClassAName(dict)
is enough to make your class act like a dict. Any dict operation you do on self
will be just like a regular dict.
How to get Color from Hexadecimal color code using .NET?
This I think is what you are after, hope it answers your question.
To get your code to work use Convert.ToByte instead of Convert.ToInt...
string colour = "#ffaacc";
Color.FromRgb(
Convert.ToByte(colour.Substring(1,2),16),
Convert.ToByte(colour.Substring(3,2),16),
Convert.ToByte(colour.Substring(5,2),16));
You can do it like this:
postData[postData.length] = { name: "variable_name", value: variable_value };
Any improvements that could be made would be micro-optimizations, the overall algorithm is correct.
On the left we have the app organized by type. Not too bad for smaller apps, but even here you can start to see it gets more difficult to find what you are looking for. When I want to find a specific view and its controller, they are in different folders. It can be good to start here if you are not sure how else to organize the code as it is quite easy to shift to the technique on the right: structure by feature.
On the right the project is organized by feature. All of the layout views and controllers go in the layout folder, the admin content goes in the admin folder, and the services that are used by all of the areas go in the services folder. The idea here is that when you are looking for the code that makes a feature work, it is located in one place. Services are a bit different as they “service” many features. I like this once my app starts to take shape as it becomes a lot easier to manage for me.

You can use this:
comment = Comment.objects.filter(pk=comment_id)
I normally concatenate the field's value (i.e. before it's updated) with the key associated with the key event. The following uses recent JS so would need adjusting for support in older IE's.
Recent JS example
document.querySelector('#test').addEventListener('keypress', function(evt) {
var real_val = this.value + String.fromCharCode(evt.which);
if (evt.which == 8) real_val = real_val.substr(0, real_val.length - 2);
alert(real_val);
}, false);
Support for older IEs example
//get field
var field = document.getElementById('test');
//bind, somehow
if (window.addEventListener)
field.addEventListener('keypress', keypress_cb, false);
else
field.attachEvent('onkeypress', keypress_cb);
//callback
function keypress_cb(evt) {
evt = evt || window.event;
var code = evt.which || evt.keyCode,
real_val = this.value + String.fromCharCode(code);
if (code == 8) real_val = real_val.substr(0, real_val.length - 2);
}
[EDIT - this approach, by default, disables key presses for things like back space, CTRL+A. The code above accommodates for the former, but would need further tinkering to allow for the latter, and a few other eventualities. See Ian Boyd's comment below.]
ROWS UNBOUNDED PRECEDING
is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY
it defines the window on which the result is calculated.
Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.
Starting and ending rows might be fixed or relative to the current row based on the following keywords:
Possible kinds of calculation include:
So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING)
results in a Cumulative Sum or Running Total
11 -> 11
2 -> 11 + 2 = 13
3 -> 13 + 3 (or 11+2+3) = 16
44 -> 16 + 44 (or 11+2+3+44) = 60
DID NOT WORK >> Set as system environment variable: I had set the environment variable in my mac bash_profile
, however, Tomcat did not see that variable.
DID NOT WORK >> setenv.sh: Apache's recommendation was to have user-defined environment variables in setenv.sh
file and I did that.
THIS WORKED!! >> After a little research into Tomcat startup scripts, I found that environment variables set using setenv.sh
are lost during the startup. So I had to edit my catalina.sh
against the recommendation of Apache and that did the trick.
Add your -DUSER_DEFINED

.

C# 9 (released with .NET 5) includes the logical patterns and
, or
and not
, which allows us to write this more elegantly:
if (child is not IContainer) { ... }
Likewise, this pattern can be used to check for null:
if (child is not null) { ... }
Look at the sample from Google called Lunar Lander, the ship image there is rotated dynamically.
I was able to achieve this by using the webkit-line-clamp
and the following css:
div {
display: -webkit-box;
-webkit-line-clamp: 1;
-webkit-box-orient: vertical;
overflow: hidden;
}
The theoretical answers from everyone else are all neat, but let's be pragmatic. ActionScript provides the tools you need so that you don't even have to write a loop in this case!
First, note that Math.min()
and Math.max()
can take any number of arguments. Also, it's important to understand the apply()
method available to Function
objects. It allows you to pass arguments to the function using an Array
. Let's take advantage of both:
var myArray:Array = [2,3,3,4,2,2,5,6,7,2];
var maxValue:Number = Math.max.apply(null, myArray);
var minValue:Number = Math.min.apply(null, myArray);
Here's the best part: the "loop" is actually run using native code (inside Flash Player), so it's faster than searching for the minimum or maximum value using a pure ActionScript loop.
Let's Encrypt is a free, automated, and open certificate authority made by the Internet Security Research Group (ISRG). It is sponsored by well-known organisations such as Mozilla, Cisco or Google Chrome. All modern browsers are compatible and trust Let's Encrypt.
All certificates are free (even wildcard certificates)! For security reasons, the certificates expire pretty fast (after 90 days). For this reason, it is recommended to install an ACME client, which will handle automatic certificate renewal.
There are many clients you can use to install a Let's Encrypt certificate:
Let’s Encrypt uses the ACME protocol to verify that you control a given domain name and to issue you a certificate. To get a Let’s Encrypt certificate, you’ll need to choose a piece of ACME client software to use. - https://letsencrypt.org/docs/client-options/
You don't escape quotes in regular expressions
this.Vals.replace(/["']/g, "")
If you are using JQuery dataTable so you need to just add "bFilter":true
. This will display default search box outside table and its works dynamically..as per expected
$("#archivedAssignments").dataTable({
"sPaginationType": "full_numbers",
"bFilter":true,
"sPageFirst": false,
"sPageLast": false,
"oLanguage": {
"oPaginate": {
"sPrevious": "<< previous",
"sNext" : "Next >>",
"sFirst": "<<",
"sLast": ">>"
}
},
"bJQueryUI": false,
"bLengthChange": false,
"bInfo":false,
"bSortable":true
});
use kubeadm reset
command. this will un-configure the kubernetes cluster.
you could put the field names into an array "fields", and then:
sql = 'select %s from table where condition1=1 and condition2=2' % (
', '.join(fields))
I had a typo
const PORT = process.env.PORT||'8080';
used to be
const PORT = process.env.port||'8080';
Note this new function:
const char* myFunction()
{
static char array[] = "my string";
return array;
}
I defined "array" as static. Otherwise when the function ends, the variable (and the pointer you are returning) gets out of scope. Since that memory is allocated on the stack, and it will get corrupted. The downside of this implementation is that the code is not reentrant and not threadsafe.
Another alternative would be to use malloc to allocate the string in the heap, and then free on the correct locations of your code. This code will be reentrant and threadsafe.
As noted in the comment, this is a very bad practice, since an attacker can then inject code to your application (he/she needs to open the code using GDB, then make a breakpoint and modify the value of a returned variable to overflow and fun just gets started).
It is much more recommended to let the caller handle about memory allocations. See this new example:
char* myFunction(char* output_str, size_t max_len)
{
const char *str = "my string";
size_t l = strlen(str);
if (l+1 > max_len) {
return NULL;
}
strcpy(str, str, l);
return input;
}
Note that the only content which can be modified is the one that the user. Another side effect - this code is now threadsafe, at least from the library point of view. The programmer calling this method should verify that the memory section used is threadsafe.
Let's say you have a column 'birth_day' in your table which is in string format, you should use the following query to filter using birth_day
date_Format(birth_day, 'yyyy-MM-dd')
You can use it in a query in the following way
select * from yourtable
where
date_Format(birth_day, 'yyyy-MM-dd') = '2019-04-16';
Not sure if this can be an answer but as I see what others have said for someone it may look like you need two separate abstractions for both of these concepts so that one of them (Future
) is just a read-only view of the other (Promise
) ... but actually this is not needed.
For example take a look at how promises are defined in javascript:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise
The focus is on the composability using the then
method like:
asyncOp1()
.then(function(op1Result){
// do something
return asyncOp2();
})
.then(function(op2Result){
// do something more
return asyncOp3();
})
.then(function(op3Result){
// do something even more
return syncOp4(op3Result);
})
...
.then(function(result){
console.log(result);
})
.catch(function(error){
console.log(error);
})
which makes asynchronous computation to look like synchronous:
try {
op1Result = syncOp1();
// do something
op1Result = syncOp2();
// do something more
op3Result = syncOp3();
// do something even more
syncOp4(op3Result);
...
console.log(result);
} catch(error) {
console.log(error);
}
which is pretty cool. (Not as cool as async-await but async-await just removes the boilerplate ....then(function(result) {.... from it).
And actually their abstraction is pretty good as the promise constructor
new Promise( function(resolve, reject) { /* do it */ } );
allows you to provide two callbacks which can be used to either complete the Promise
successfully or with an error. So that only the code that constructs the Promise
can complete it and the code that receives an already constructed Promise
object has the read-only view.
With inheritance the above can be achieved if resolve and reject are protected methods.
For VBScript use FormatDateTime, which has 5 numerical arguments to give you one of 5 predefined formats. Its not great.
FormatDateTime(now, 4)

CPU Bound means the rate at which process progresses is limited by the speed of the CPU. A task that performs calculations on a small set of numbers, for example multiplying small matrices, is likely to be CPU bound.
I/O Bound means the rate at which a process progresses is limited by the speed of the I/O subsystem. A task that processes data from disk, for example, counting the number of lines in a file is likely to be I/O bound.
Memory bound means the rate at which a process progresses is limited by the amount memory available and the speed of that memory access. A task that processes large amounts of in memory data, for example multiplying large matrices, is likely to be Memory Bound.
Cache bound means the rate at which a process progress is limited by the amount and speed of the cache available. A task that simply processes more data than fits in the cache will be cache bound.
I/O Bound would be slower than Memory Bound would be slower than Cache Bound would be slower than CPU Bound.
The solution to being I/O bound isn't necessarily to get more Memory. In some situations, the access algorithm could be designed around the I/O, Memory or Cache limitations. See Cache Oblivious Algorithms.
In python, when you have an iterable, usually you iterate without an index:
letters = 'abcdef' # or a list, tupple or other iterable
for l in letters:
print(l)
If you need to traverse the iterable in reverse order, you would do:
for l in letters[::-1]:
print(l)
When for any reason you need the index, you can use enumerate
:
for i, l in enumerate(letters, start=1): #start is 0 by default
print(i,l)
You can enumerate in reverse order too...
for i, l in enumerate(letters[::-1])
print(i,l)
ON ANOTHER NOTE...
Usually when we traverse an iterable we do it to apply the same procedure or function to each element. In these cases, it is better to use map
:
If we need to capitilize each letter:
map(str.upper, letters)
Or get the Unicode code of each letter:
map(ord, letters)
I know this is not possible for alert(), so I guess it is not possible for confirm either. Reason is security: it is not allowed for you to change it so you wouldn't present yourself as some system process or something.
UIStoryboard * storyboard = [UIStoryboard storyboardWithName:@"Tutorial" bundle:nil];
self.window.rootViewController = [storyboard instantiateInitialViewController];
if you got troubles with windows cmd command and .bat just escape percents like that
git show -s --format=%%ct
The % character has a special meaning for command line parameters and FOR parameters. To treat a percent as a regular character, double it: %%
Use the sleep
command.
Example:
sleep .5 # Waits 0.5 second.
sleep 5 # Waits 5 seconds.
sleep 5s # Waits 5 seconds.
sleep 5m # Waits 5 minutes.
sleep 5h # Waits 5 hours.
sleep 5d # Waits 5 days.
One can also employ decimals when specifying a time unit; e.g. sleep 1.5s
ALTER USER
Example:
ALTER USER 'username' IDENTIFIED BY 'password';
Because:
SET PASSWORD ... = PASSWORD('auth_string')
syntax is deprecated as of MySQL 5.7.6 and will be removed in a future MySQL release.
SET PASSWORD ... = 'auth_string'
syntax is not deprecated, but ALTER USER
is now the preferred statement for assigning passwords.
To me, this looks like the simplest/fastest:
$('form input[type=submit]').click(function() { // attach the listener to your button
var yourWantedObjectIsHere = $(this.form); // use the native JS object with `this`
});
SELECT <column_list>
FROM TABLEA a
LEFTJOIN TABLEB b
ON a.Key = b.Key
WHERE b.Key IS NULL;

You can actualy fake the transparency of option
DOMElements with the following CSS:
option {
/* Whatever color you want */
background-color: #82caff;
}
The option

If you just disable only scroll functionality of RecyclerView
then you can use setLayoutFrozen(true);
method of RecyclerView
. But it can not be disable touch event.
your_recyclerView.setLayoutFrozen(true);
The following worked for me
conda install libxgboost
From the manual:
SET NAMES indicates what character set the client will use to send SQL statements to the server.
More elaborately, (and once again, gratuitously lifted from the manual):
SET NAMES indicates what character set the client will use to send SQL statements to the server. Thus, SET NAMES 'cp1251' tells the server, “future incoming messages from this client are in character set cp1251.” It also specifies the character set that the server should use for sending results back to the client. (For example, it indicates what character set to use for column values if you use a SELECT statement.)
It might not exactly be the same error, but I had a similar one.
Check Maven Java Version
Since Maven is also runnig with Java, check first with which version your Maven is running on:
mvn --version | grep -i java
It returns:
Java version 1.8.0_151, vendor: Oracle Corporation, runtime: C:\tools\jdk\openjdk1.8
Incompatible version
Here above my maven is running with Java Version 1.8.0_151
.
So even if I specify maven to compile with Java 11
:
<properties>
<java.version>11</java.version>
<maven.compiler.source>${java.version}</maven.compiler.source>
<maven.compiler.target>${java.version}</maven.compiler.target>
</properties>
It will logically print out this error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project efa-example-commons-task: Fatal error compiling: invalid target release: 11 -> [Help 1]
How to set specific java version to Maven
The logical thing to do is to set a higher Java Version to Maven (e.g. Java version 11 instead 1.8).
Maven make use of the environment variable JAVA_HOME
to find the Java Version to run. So change this variable to the JDK you want to compile against (e.g. OpenJDK 11).
Sanity check
Then run again mvn --version
to make sure the configuration has been taken care of:
mvn --version | grep -i java
yields
Java version: 11.0.2, vendor: Oracle Corporation, runtime: C:\tools\jdk\openjdk11
Which is much better and correct to compile code written with the Java 11 specifications.
use only see a tables

if want to see schema tables

if you want to see specific schema tables

Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.
git checkout
modifies your working tree,git reset
modifies which reference the branch you're on points to,git revert
adds a commit undoing changes.An easy way to check the CPU usage is to use the adb tool w/ top. I.e.:
adb shell top -m 10
If you want to do something like the following example, you'd have to use nested if
s.
If percentage is greater than or equal to 93%, then corresponding value in B should be 4 and if the percentage is greater than or equal to 90% and less than 92%, then corresponding value in B to be 3.7, etc.
Here's how you'd do it:
=IF(A2>=93%, 4, IF(A2>=90%, 3.7,IF(A2>=87%,3.3,0)))

uint8
, uint16
, uint32
, and uint64
are probably Microsoft-specific types.
As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>
: uint8_t
, uint16_t
, uint32_t
, and uint64_t
. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>
, at least as of Visual Studio 2010, but older code may use uint8
et al.
The predefined types char
, short
, int
et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char
is at least 8 bits, short
and int
are at least 16, long
is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int
is 16, 32, or 64 bits.
char
is almost always exactly 8 bits, but it's permitted to be wider. And plain char
may be either signed or unsigned.
uint8_t
is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char
, though it might be a typedef for plain char
if plain char
happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t
will not be defined at all.
Similarly, each uintN_t
type is an unsigned type that's exactly N bits wide.
In addition, <stdint.h>
defines corresponding signed intN_t
types, as well as int_fastN_t
and int_leastN_t
types that are at least the specified width.
The [u]intN_t
types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t
types are required to use a 2's-complement representation.
Although uint32_t
might be the same as unsigned int
, for example, you shouldn't assume that. Use unsigned int
when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t
when you need an unsigned integer type that's exactly 32 bits wide.
(And no, uint64
or uint64_t
is not the same as double
; double
is a floating-point type.)
Perhaps it would help to know does it mean for the hardware to be "designed for this environment". How does it correct and/or indicates the presence of SEU errors ?
At one space exploration related project, we had a custom MCU, which would raise an exception/interrupt on SEU errors, but with some delay, i.e. some cycles may pass/instructions be executed after the one insn which caused the SEU exception.
Particularly vulnerable was the data cache, so a handler would invalidate the offending cache line and restart the program. Only that, due to the imprecise nature of the exception, the sequence of insns headed by the exception raising insn may not be restartable.
We identified the hazardous (not restartable) sequences (like lw $3, 0x0($2)
, followed by an insn, which modifies $2
and is not data-dependent on $3
), and I made modifications to GCC, so such sequences do not occur (e.g. as a last resort, separating the two insns by a nop
).
Just something to consider ...
You can press ctrl+t to get a editor Get to all , in which you can type the file name to navigate to that specific file.
If you don't want to use the libraries and want simple answer then the code is given below:
def swap_alpha(test_string):
new_string = ""
for i in test_string:
if i.upper() in test_string:
new_string += i.lower()
elif i.lower():
new_string += i.upper()
else:
return "invalid "
return new_string
user_string = input("enter the string:")
updated = swap_alpha(user_string)
print(updated)
