Use this code ,when you want to refresh your datatable:
$("#my-button").click(function() {
$('#my-datatable').DataTable().clear().draw();
});
It is Work for me:
language:{"infoEmpty": "No records available",}
If you already have to hide Some columns, like I hide last name column. I just had to concatenate fname , lname , So i made query but hide that column from front end. The modifications in Disable sorting in such situation are :
"aoColumnDefs": [
{ 'bSortable': false, 'aTargets': [ 3 ] },
{
"targets": [ 4 ],
"visible": false,
"searchable": true
}
],
Notice that I had Hiding functionality here
"columnDefs": [
{
"targets": [ 4 ],
"visible": false,
"searchable": true
}
],
Then I merged it into "aoColumnDefs"
You should try this one.
var table = $('#example').DataTable();
table.columns.adjust().draw();
The best solution I found this to work for me guys after trying all the other solutions.... Basically i set the sScrollX to 200% then set the individual column widths to the required % that I wanted. The more columns that you have and the more space that you require then you need to raise the sScrollX %... The null means that I want those columns to retain the datatables auto width they have set in their code.
$('#datatables').dataTable
({
"sScrollX": "200%", //This is what made my columns increase in size.
"bScrollCollapse": true,
"sScrollY": "320px",
"bAutoWidth": false,
"aoColumns": [
{ "sWidth": "10%" }, // 1st column width
{ "sWidth": "null" }, // 2nd column width
{ "sWidth": "null" }, // 3rd column width
{ "sWidth": "null" }, // 4th column width
{ "sWidth": "40%" }, // 5th column width
{ "sWidth": "null" }, // 6th column width
{ "sWidth": "null" }, // 7th column width
{ "sWidth": "10%" }, // 8th column width
{ "sWidth": "10%" }, // 9th column width
{ "sWidth": "40%" }, // 10th column width
{ "sWidth": "null" } // 11th column width
],
"bPaginate": true,
"sDom": '<"H"TCfr>t<"F"ip>',
"oTableTools":
{
"aButtons": [ "copy", "csv", "print", "xls", "pdf" ],
"sSwfPath": "copy_cvs_xls_pdf.swf"
},
"sPaginationType":"full_numbers",
"aaSorting":[[0, "desc"]],
"bJQueryUI":true
});
var table;
$(document).ready(function() {
//datatables
table = $('#userTable').DataTable({
"processing": true, //Feature control the processing indicator.
"serverSide": true, //Feature control DataTables' server-side processing mode.
"order": [], //Initial no order.
"aaSorting": [],
// Load data for the table's content from an Ajax source
"ajax": {
"url": "<?php echo base_url().'admin/ajax_list';?>",
"type": "POST"
},
//Set column definition initialisation properties.
"columnDefs": [
{
"targets": [ ], //first column / numbering column
"orderable": false, //set not orderable
},
],
});
});
set
"targets": [0]
to
"targets": [ ]
I was having same issue, and the solution was working but with some alerts and warnings so here is full solution, the key was to check for existing DataTable object or not, if yes just clear the table and add jsonData, if not just create new.
var table;
if ($.fn.dataTable.isDataTable('#example')) {
table = $('#example').DataTable();
table.clear();
table.rows.add(jsonData).draw();
}
else {
table = $('#example').DataTable({
"data": jsonData,
"deferRender": true,
"pageLength": 25,
"retrieve": true,

I contribute with my settings for buttons: view, edit and delete. The last column has data: null At the end with the property defaultContent is added a string that HTML code. And since it is the last column, it is indicated with index -1 by means of the targets property when indicating the columns.

Based on the docs, xhr
Ajax event would fire when an Ajax request is completed. So you can do something like this:
let data_table = $('#example-table').dataTable({
ajax: "data.json"
});
data_table.on('xhr.dt', function ( e, settings, json, xhr ) {
// Do some staff here...
$('#status').html( json.status );
} )
In the initialization use:
"fnServerData": function ( sSource, aoData, fnCallback ) {
//* Add some extra data to the sender *
newData = aoData;
newData.push({ "name": "key", "value": $('#value').val() });
$.getJSON( sSource, newData, function (json) {
//* Do whatever additional processing you want on the callback, then tell DataTables *
fnCallback(json);
} );
},
And then just use:
$("#table_id").dataTable().fnDraw();
The important thing in the fnServerData is:
newData = aoData;
newData.push({ "name": "key", "value": $('#value').val() });
if you push directly to aoData, the change is permanent the first time you draw the table and fnDraw don't work the way you want.
You can try setting the word-wrap
however it doesn't work in all browsers yet.
Another method would be to add an element around your cell data like this:
<td><span>...</span></td>
Then add some css like this:
.datatable td span{
max-width: 400px;
display: block;
overflow: hidden;
}
I may be arising by aoColumns field. As stated HERE
aoColumns: If specified, then the length of this array must be equal to the number of columns in the original HTML table. Use 'null' where you wish to use only the default values and automatically detected options.
Then you have to add fields as in table Columns
...
aoColumnDefs: [
null,
null,
null,
{ "bSortable": false },
null,
],
...
Best option is to disable sorting and just feed data with desired sort order (from database or other source). Try to add this to your 'datatable': "bSort": false
This should work for you:
let example = $('#example').DataTable({
columnDefs: [{
orderable: false,
className: 'select-checkbox',
targets: 0
}],
select: {
style: 'os',
selector: 'td:first-child'
},
order: [
[1, 'asc']
]
});
example.on("click", "th.select-checkbox", function() {
if ($("th.select-checkbox").hasClass("selected")) {
example.rows().deselect();
$("th.select-checkbox").removeClass("selected");
} else {
example.rows().select();
$("th.select-checkbox").addClass("selected");
}
}).on("select deselect", function() {
("Some selection or deselection going on")
if (example.rows({
selected: true
}).count() !== example.rows().count()) {
$("th.select-checkbox").removeClass("selected");
} else {
$("th.select-checkbox").addClass("selected");
}
});
I've added to the CSS though:
table.dataTable tr th.select-checkbox.selected::after {
content: "?";
margin-top: -11px;
margin-left: -4px;
text-align: center;
text-shadow: rgb(176, 190, 217) 1px 1px, rgb(176, 190, 217) -1px -1px, rgb(176, 190, 217) 1px -1px, rgb(176, 190, 217) -1px 1px;
}
Working JSFiddle, hope that helps.
Here is an alternative that is an incremental improvement on several other answers. Assuming settings.aLengthMenu is not multi-dimensional (it can be when DataTables has row lengths and labels) and the data will not change after page load (for simple DOM-loaded DataTables), this function can be inserted to eliminate paging. It hides several paging-related classes.
Perhaps more robust would be setting paging to false inside the function below, however I don't see an API call for that off-hand.
$('#myTable').on('init.dt', function(evt, settings) {
if (settings && settings.aLengthMenu && settings.fnRecordsTotal && settings.fnRecordsTotal() < settings.aLengthMenu[0]) {
// hide pagination controls, fewer records than minimum length
$(settings.nTableWrapper).find('.dataTables_paginate, .dataTables_length, .dataTables_info').hide();
}
}).DataTable();
There are language files uploaded in a CDN on the dataTables website https://datatables.net/plug-ins/i18n/ So you only have to replace "Spanish" with whatever language you are using in the following example.
https://datatables.net/plug-ins/i18n/Spanish
$('table.dataTable').DataTable( {
language: {
url: '//cdn.datatables.net/plug-ins/1.10.15/i18n/Spanish.json'
}
});
In my case, I am not using the built in ajax api to feed Json to the table (this is due to some formatting that was rather difficult to implement inside the datatable's render callback).
My solution was to create the variable in the outer scope of the onload functions and the function that handles the data refresh (var table = null
, for example).
Then I instantiate my table in the on load method
$(function () {
//.... some code here
table = $("#detailReportTable").DataTable();
.... more code here
});
and finally, in the function that handles the refresh, i invoke the clear() and destroy() method, fetch the data into the html table, and re-instantiate the datatable, as such:
function getOrderDetail() {
table.clear();
table.destroy();
...
$.ajax({
//.....api call here
});
....
table = $("#detailReportTable").DataTable();
}
I hope someone finds this useful!
According to datatables.net the proper way to do this is adding the lengthMenu property with an array of values.
$(document).ready(function() {
$('#example').dataTable( {
"lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]]
} );
} );
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
});
In my case, the 'page.dt' event did not do the trick.
I used 'draw.dt' event instead, and it works!, some code:
$(document).on('draw.dt', function () {
//Do something
});
'Draw.dt' event is fired everytime the datatable page change by searching, ordering or page changing.
/***** Aditional Info *****/
There are some diferences in the way we can declare the event listener. You can asign it to the 'document' or to a 'html object'. The 'document' listeners will always exist in the page and the 'html object' listener will exist only if the object exist in the DOM in the moment of the declaration. Some code:
//Document event listener
$(document).on('draw.dt', function () {
//This will also work with objects loaded by ajax calls
});
//HTML object event listener
$("#some-id").on('draw.dt', function () {
//This will work with existing objects only
});
<script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.min.js"defer</script>
Add Defer to the end of your Script tag, it worked for me (;
Everything needs to be loaded in the correct order (:
By default the grid view will take care, just pass empty data set.
Use:
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
The option you should use is iDisplayLength:
$('#adminProducts').dataTable({
'iDisplayLength': 100
});
$('#table').DataTable({
"lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});
It will Load by default all entries.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
If you want to load by default 25 not all do this.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
});
I resolved this error, by replacing the src attribute with https://code.jquery.com/jquery-3.5.1.min.js, the problem is caused by the slim version of JQuery.
Click on the "show details" link under Date (dd/mm/YYY), then you can copy and paste that plugin code provided there
Update: I think you can just switch the order of the array, like so:
jQuery.fn.dataTableExt.oSort['us_date-asc'] = function(a,b) {
var usDatea = a.split('/');
var usDateb = b.split('/');
var x = (usDatea[2] + usDatea[0] + usDatea[1]) * 1;
var y = (usDateb[2] + usDateb[0] + usDateb[1]) * 1;
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
};
jQuery.fn.dataTableExt.oSort['us_date-desc'] = function(a,b) {
var usDatea = a.split('/');
var usDateb = b.split('/');
var x = (usDatea[2] + usDatea[0] + usDatea[1]) * 1;
var y = (usDateb[2] + usDateb[0] + usDateb[1]) * 1;
return ((x < y) ? 1 : ((x > y) ? -1 : 0));
};
All I did was switch the __date_[1]
(day) and __date_[0]
(month), and replaced uk
with us
so you won't get confused. I think that should take care of it for you.
Update #2: You should be able to just use the date object for comparison. Try this:
jQuery.fn.dataTableExt.oSort['us_date-asc'] = function(a,b) {
var x = new Date(a),
y = new Date(b);
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
};
jQuery.fn.dataTableExt.oSort['us_date-desc'] = function(a,b) {
var x = new Date(a),
y = new Date(b);
return ((x < y) ? 1 : ((x > y) ? -1 : 0));
};
EDIT: See the latest Fiddle with "fixed header":
The Fiddle.
One of the solutions is to implement scrolling yourself instead of letting DataTables plugin do it for you.
I've taken your example and commented out sScrollX option. When this option is not present DataTables plugin will simply put your table as is into a container div. This table will stretch out of the screen, therefore, to fix that we can put it into a div with required width and an overflow property set - this is exactly what the last jQuery statement does - it wraps existing table into a 300px wide div. You probably will not need to set the width on the wrapping div at all (300px in this example), I have it here so that clipping effect is easily visible. And be nice, don't forget to replace that inline style with a class.
$(document).ready(function() {
var stdTable1 = $(".standard-grid1").dataTable({
"iDisplayLength": -1,
"bPaginate": true,
"iCookieDuration": 60,
"bStateSave": false,
"bAutoWidth": false,
//true
"bScrollAutoCss": true,
"bProcessing": true,
"bRetrieve": true,
"bJQueryUI": true,
//"sDom": 't',
"sDom": '<"H"CTrf>t<"F"lip>',
"aLengthMenu": [[25, 50, 100, -1], [25, 50, 100, "All"]],
//"sScrollY": "500px",
//"sScrollX": "100%",
"sScrollXInner": "110%",
"fnInitComplete": function() {
this.css("visibility", "visible");
}
});
var tableId = 'PeopleIndexTable';
$('<div style="width: 300px; overflow: auto"></div>').append($('#' + tableId)).insertAfter($('#' + tableId + '_wrapper div').first())});
I would like to develop the current answer.
The good way is to use aoColumnDefs
as mentioned.
The default value for the bSortable
parameter is true
(for each column).
You've got 2 options...
var table = $('#example').DataTable({
'aoColumnDefs': [{
'bSortable': false,
'aTargets': [-1] /* 1st one, start by the right */
}]
});
var table = $('#example').DataTable({
'aoColumnDefs': [{
'bSortable': false,
'aTargets': ['nosort']
}]
});
Adding the class on the <th>
:
<table>
<thead>
<tr>
<th>Foo</th>
<th>Bar</th>
<th class="nosort">Baz</th>
</tr>
</thead>
<tbody>...</tbody>
</table>
Here is DataTable
with Single DatePicker
as "from" Date Filter
Here is DataTable
with Two DatePickers
for DateRange (To and From) Filter
You have to destroy the datatable and empty the table body before binding DataTable by doing this below,
function Create() {
if ($.fn.DataTable.isDataTable('#dataTable')) {
$('#dataTable').DataTable().destroy();
}
$('#dataTable tbody').empty();
//Here call the Datatable Bind function;}
Check this solution too. this solved my DataTable column width issue easily
JQuery DataTables 1.10.20 introduces columns.adjust()
method which fix Bootstrap toggle tab issue
$('a[data-toggle="tab"]').on( 'shown.bs.tab', function (e) {
$.fn.dataTable.tables( {visible: true, api: true} ).columns.adjust();
} );
Please refer the documentation : Scrolling and Bootstrap tabs
In my case, i had to assign my json to an attribute called aaData just like in Datatables ajax example which data looked like this.
None of these solutions worked for me, but I did do something similar to Masood's answer. Here it is for posterity. This assumes you have <table id="mytable"></table>
in your page somewhere:
function generate_support_user_table() {
$('#mytable').hide();
$('#mytable').dataTable({
...
"bDestroy": true,
"fnInitComplete": function () { $('#support_user_table').show(); },
...
});
}
The important parts are:
bDestroy
, which wipes out the current table before loading.hide()
call and fnInitComplete
, which ensures that the table only appears after everything is loaded. Otherwise it resizes and looks weird while loading.Just add the function call to $(document).ready()
and you should be all set. It will load the table initially, as well as reload later on a button click or whatever.
I solved this problem by wrapping the "dataTable" Table with a div
with overflow:auto
:
.dataTables_scroll
{
overflow:auto;
}
and adding this JS after your dataTable
initialization:
jQuery('.dataTable').wrap('<div class="dataTables_scroll" />');
Don't use sScrollX
or sScrollY
, remove them and add a div
wrapper yourself which does the same thing.
This way it worked for me.
<td data-order="@item.CreatedOn.ToString("MMddyyyyHHmmss")">
@item.CreatedOn.ToString("dd-MM-yyyy hh:mm tt")
</td>
This date format in data-order
attribute should be in this format which is being supported by DataTable.
var example = $('#exampleTable').DataTable({
"columnDefs": [
{
"targets": [0],
"visible": false,
"searchable": false
}
]
});
Target attribute defines the position of the column.Visible attribute responsible for visibility of the column.Searchable attribute responsible for searching facility.If it set to false that column doesn't function with searching.
I have tried in many ways. The only way that worked for me was:
The Yush0 CSS solution:
#yourTable{
table-layout: fixed !important;
word-wrap:break-word;
}
Together with Roy Jackson HTML Solution:
<th style='width: 5%;'>ProjectId</th>
<th style='width: 15%;'>Title</th>
<th style='width: 40%;'>Abstract</th>
<th style='width: 20%;'>Keywords</th>
<th style='width: 10%;'>PaperName</th>
<th style='width: 10%;'>PaperURL</th>
</tr>
If you only want to hide the search form for example because you have column input filters or may be because you already have a CMS search form able to return results from the table then all you have to do is inspect the form and get its id - (at the time of writing this, it looks as such[tableid]-table_filter.dataTables_filter
). Then simply do [tableid]-table_filter.dataTables_filter{display:none;}
retaining all other features of datatables.
You Can Remove Char using below Line ,
:- First check That String has enough char to remove ,like
string temp="Hello Stack overflow";
if(temp.Length>10)
{
string textIWant = temp.Remove(0, 10);
}
as JSON only allows enclosing strings with double quotes you can manipulate the string like this:
str = str.replace("\'", "\"")
if your JSON holds escaped single-quotes (\'
) then you should use the more precise following code:
import re
p = re.compile('(?<!\\\\)\'')
str = p.sub('\"', str)
This will replace all occurrences of single quote with double quote in the JSON string str
and in the latter case will not replace escaped single-quotes.
You can also use js-beautify
which is less strict:
$ pip install jsbeautifier
$ js-beautify file.js
Use the Maven debug option, ie mvn -X

Using AFNetworking 3.0, you should write:

AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];

break
is used to exit (escape) the for
-loop, while
-loop, switch
-statement that you are currently executing.
return
will exit the entire method you are currently executing (and possibly return a value to the caller, optional).
So to answer your question (as others have noted in comments and answers) you cannot use either break
nor return
to escape an if-else
-statement per se. They are used to escape other scopes.
Consider the following example. The value of x
inside the while
-loop will determine if the code below the loop will be executed or not:
void f()
{
int x = -1;
while(true)
{
if(x == 0)
break; // escape while() and jump to execute code after the the loop
else if(x == 1)
return; // will end the function f() immediately,
// no further code inside this method will be executed.
do stuff and eventually set variable x to either 0 or 1
...
}
code that will be executed on break (but not with return).

You're after the zip function.
Taken directly from the question: How to merge lists into a list of tuples in Python?
>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]

[(1, 5), (2, 6), (3, 7), (4, 8)]
I don't really understand the full scope of your question, but if all you need is a hash of the string, then it's very easy to get that.
Just use the GetHashCode method.
Like this:
string hash = username.GetHashCode();
Go into File ? Settings ? Project Settings ? Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.
You can also do this:
var x = new object[] {
new { firstName = "john", lastName = "walter" },
new { brand = "BMW" }
};
And if they are the same anonymous type (firstName and lastName), you won't need to cast as object
.

Below is the work around for chrome for local testing
You need to open your chrome with following command. (Press window+R)
Chrome.exe --allow-file-access-from-files
Note : Your chrome must not be open. When you run this command chrome will open automatically.
If you are entering this command in command prompt then select your chrome installation directory then use this command.
Below script code for open chrome in MAC with "--allow-file-access-from-files"
set chromePath to POSIX path of "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
set switch to " --allow-file-access-from-files"
do shell script (quoted form of chromePath) & switch & " > /dev/null 2>&1 &"
second options
You can just use open(1) to add the flags: open -a 'Google Chrome' --args --allow-file-access-from-files
It's not working because console.log() it's not in a "executable area" of the class "App".
A class is a structure composed by attributes and methods.
The only way to have your code executed is to place it inside a method that is going to be executed. For instance: constructor()
console.log('It works here')_x000D_
_x000D_
@Component({..)_x000D_
export class App {_x000D_
s: string = "Hello2";_x000D_
_x000D_
constructor() {_x000D_
console.log(this.s) _x000D_
} _x000D_
}
_x000D_
Think of class like a plain javascript object.
Would it make sense to expect this to work?
class: {_x000D_
s: string,_x000D_
console.log(s)_x000D_
}
_x000D_
If you still unsure, try the typescript playground where you can see your typescript code generated into plain javascript.
The SQL Server login required is DOMAIN\machinename$

appears to SQL Server (and file servers etc)
In SQL,

You can install brew using below command.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
However, while using this you will get warning that it buy homebrew installer is now deprecated. Recommended to use Bash instead.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Just copy "editor.fontSize": 18
into your setting.json
of the editor.
Pressing Control+Shift+P and then typing "settings" will allow you to easily find the user or workspace settings file.
I usually use some #define and constants to make the calculation easy:
#define NANO_SECOND_MULTIPLIER 1000000 // 1 millisecond = 1,000,000 Nanoseconds
const long INTERVAL_MS = 500 * NANO_SECOND_MULTIPLIER;
Hence my code would look like this:
timespec sleepValue = {0};
sleepValue.tv_nsec = INTERVAL_MS;
nanosleep(&sleepValue, NULL);
If you are on ubuntu, just install pyqt5 with apt-get
command:
sudo apt-get install python3-pyqt5 # for python3
or
sudo apt-get install python-pyqt5 # for python2
However, on Ubuntu 14.04 the python-pyqt5 package is left out [source] and need to be installed manually [source]
By playing with parameters as -XX:PermSize
and -Xms
you can tune the performance of - for example - the startup of your application. I haven't looked at it recently, but a few years back the default value of -Xms
was something like 32MB (I think), if your application required a lot more than that it would trigger a number of cycles of fill memory - full garbage collect - increase memory etc until it had loaded everything it needed. This cycle can be detrimental for startup performance, so immediately assigning the number required could improve startup.
A similar cycle is applied to the permanent generation. So tuning these parameters can improve startup (amongst others).
WARNING The JVM has a lot of optimization and intelligence when it comes to allocating memory, dividing eden space and older generations etc, so don't do things like making -Xms
equal to -Xmx
or -XX:PermSize
equal to -XX:MaxPermSize
as it will remove some of the optimizations the JVM can apply to its allocation strategies and therefor reduce your application performance instead of improving it.
As always: make non-trivial measurements to prove your changes actually improve performance overall (for example improving startup time could be disastrous for performance during use of the application)
here's an idea... just pull down one full page of results from each of the three and then throw out the 20 least useful ones... this eliminates the large querysets and that way you only sacrifice a little performance instead of a lot
Perhaps the easiest is to use position: absolute
to fix to the bottom, then a suitable margin/padding to make sure that the other text doesn't spill over the top of it.
css:
<style>
body {
margin: 0 0 20px;
}
.footer {
position: absolute;
bottom: 0;
height: 20px;
background: #f0f0f0;
width: 100%;
}
</style>
Here is the html main content.
<div class="footer"> Here is the footer. </div>
For completeness sake, since Ruby 1.9 String#chr returns the first character of a string. Its still available in 2.0 and 2.1.
"Smith".chr #=> "S"
You can make it a KeyValuePair, so it will return a "IEnumerable<KeyValuePair<string, string>>"
So, it will be like this:
.Select(i => new KeyValuePair<string, string>(i.category_id, i.category_name )).Distinct();
You can use a modulus to get the remainder. Though @cnicutar's answer seems cleaner/more direct.
Since you haven't given any indication to what you want, here is a link to 101 LINQ samples that use all the different LINQ methods: 101 LINQ Samples
Also, you should really really really change your List
into a strongly typed list (List<T>
), properly define T, and add instances of T to your list. It will really make the queries much easier since you won't have to cast everything all the time.
I think jinja deliberately makes it difficult to run 'arbitrary' python within a template. It tries to enforce the opinion that less logic in templates is a good thing.
You can manipulate the global namespace within an Environment
instance to add references to your functions. It must be done before you load any templates. For example:
from jinja2 import Environment, FileSystemLoader
def clever_function(a, b):
return u''.join([b, a])
env = Environment(loader=FileSystemLoader('/path/to/templates'))
env.globals['clever_function'] = clever_function

TL;DR: Check the path to your keystore.jks
file.
In my case, here's what happened:
I moved the project folder of my entire app to another location on my PC. Much later, I wanted to generate a signed apk file. Unknown to me, the default location of the path to my keystore.jks
had been reset to a wrong location and I had clicked okay. Since it could not find a keystore at the path I selected, I got that error.
The solution was to check whether the path to my keystore.jks
file was correct.
This is my solution:
function getDataLine(grida, rowid){ //vykradeno z inineeditu a vohackovano
if(grida.lastIndexOf("#", 0) === 0){
grida = $(grida);
}else{
grida = $("#"+grida);
}
var nm, tmp={}, tmp2={}, tmp3= {}, editable, fr, cv, ind;
ind = grida.jqGrid("getInd",rowid,true);
if(ind === false) {return success;}
editable = $(ind).attr("editable");
if (editable==="1") {
var cm;
var colModel = grida.jqGrid("getGridParam","colModel") ;
$("td",ind).each(function(i) {
// cm = $('#mygrid').p.colModel[i];
cm = colModel[i];
nm = cm.name;
if ( nm != 'cb' && nm != 'subgrid' && cm.editable===true && nm != 'rn' && !$(this).hasClass('not-editable-cell')) {
switch (cm.edittype) {
case "checkbox":
var cbv = ["Yes","No"];
if(cm.editoptions ) {
cbv = cm.editoptions.value.split(":");
}
tmp[nm]= $("input",this).is(":checked") ? cbv[0] : cbv[1];
break;
case 'text':
case 'password':
case 'textarea':
case "button" :
tmp[nm]=$("input, textarea",this).val();
break;
case 'select':
if(!cm.editoptions.multiple) {
tmp[nm] = $("select option:selected",this).val();
tmp2[nm] = $("select option:selected", this).text();
} else {
var sel = $("select",this), selectedText = [];
tmp[nm] = $(sel).val();
if(tmp[nm]) { tmp[nm]= tmp[nm].join(","); } else { tmp[nm] =""; }
$("select option:selected",this).each(
function(i,selected){
selectedText[i] = $(selected).text();
}
);
tmp2[nm] = selectedText.join(",");
}
if(cm.formatter && cm.formatter == 'select') { tmp2={}; }
break;
}
}
});
}
return tmp;

Another option to make PostgreSQL use an index for your original query, is to create an index on the expression you are using:
create index arrival_year on reservations ( extract(year from arrival) );
That will open PostgreSQL with the possibility to use an index for
select *
FROM reservations
WHERE extract(year from arrival) = 2012;
Note that the expression in the index must be exactly the same expression as used in the where
clause to make this work.
It's something like this, for a dotnet 2.x core console application:
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
[...]
var configuration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
var serviceProvider = new ServiceCollection()
.AddLogging(options => options.AddConfiguration(configuration).AddConsole())
.AddSingleton<IConfiguration>(configuration)
.AddSingleton<SomeService>()
.BuildServiceProvider();
[...]
await serviceProvider.GetService<SomeService>().Start();
The you could inject ILoggerFactory, IConfiguration in the SomeService
.
Jenkins Pipeline also provides the current build number as the property number
of the currentBuild
. It can be read as currentBuild.number
.
For example:
// Scripted pipeline
def buildNumber = currentBuild.number
// Declarative pipeline
echo "Build number is ${currentBuild.number}"
Other properties of currentBuild
are described in the Pipeline Syntax: Global Variables page that is included on each Pipeline job page. That page describes the global variables available in the Jenkins instance based on the current plugins.
There's no way to specify a StringComparer
at the point where you try to get a value. If you think about it, "foo".GetHashCode()
and "FOO".GetHashCode()
are totally different so there's no reasonable way you could implement a case-insensitive get on a case-sensitive hash map.
You can, however, create a case-insensitive dictionary in the first place using:-
var comparer = StringComparer.OrdinalIgnoreCase;
var caseInsensitiveDictionary = new Dictionary<string, int>(comparer);
Or create a new case-insensitive dictionary with the contents of an existing case-sensitive dictionary (if you're sure there are no case collisions):-
var oldDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var newDictionary = new Dictionary<string, int>(oldDictionary, comparer);
This new dictionary then uses the GetHashCode()
implementation on StringComparer.OrdinalIgnoreCase
so comparer.GetHashCode("foo")
and comparer.GetHashcode("FOO")
give you the same value.
Alternately, if there are only a few elements in the dictionary, and/or you only need to lookup once or twice, you can treat the original dictionary as an IEnumerable<KeyValuePair<TKey, TValue>>
and just iterate over it:-
var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var value = myDictionary.FirstOrDefault(x => String.Equals(x.Key, myKey, comparer)).Value;
Or if you prefer, without the LINQ:-
var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
int? value;
foreach (var element in myDictionary)
{
if (String.Equals(element.Key, myKey, comparer))
{
value = element.Value;
break;
}
}
This saves you the cost of creating a new data structure, but in return the cost of a lookup is O(n) instead of O(1).
I resolved my problem doing this:
json_encode($array, JSON_UNESCAPED_UNICODE)
to encode the data;The result is a .json file encoded to ANSI as UTF-8.
If you don't care about the icon looking pretty on all sort of Apple devices, just add
get '/:apple_touch_icon' => redirect('/icon.png'), constraints: { apple_touch_icon: /apple-touch-icon(-\d+x\d+)?(-precomposed)?\.png/ }
to your config/routes.rb
file and some icon.png
to your public
directory. Redirecting to 404.html
instead of icon.png
works too.
Server side put this on top of .php:
header('Access-Control-Allow-Origin: *');
You can set specific domain restriction access:
header('Access-Control-Allow-Origin: https://www.example.com')
Take a look at this article on Simple-talk.com by Pop Rivett. It walks you through creating a generic trigger that will log the OLDVALUE and the NEWVALUE for all updated columns. The code is very generic and you can apply it to any table you want to audit, also for any CRUD operation i.e. INSERT, UPDATE and DELETE. The only requirement is that your table to be audited should have a PRIMARY KEY (which most well designed tables should have anyway).
Here's the code relevant for your GUESTS Table.

Alternatively you can use a Docker image which already has ping installed, e.g. busybox:
docker run --rm busybox ping SERVER_NAME -c 2
Since PostgreSQL 9.1, installation of additional modules is simple. Registered extensions like dblink
can be installed with CREATE EXTENSION
:
CREATE EXTENSION dblink;
Installs into your default schema, which is public
by default. Make sure your search_path
is set properly before you run the command. The schema must be visible to all roles who have to work with it. See:
Alternatively, you can install to any schema of your choice with:
CREATE EXTENSION dblink SCHEMA extensions;
See:
Run once per database. Or run it in the standard system database template1
to add it to every newly created DB automatically. Details in the manual.
You need to have the files providing the module installed on the server first. For Debian and derivatives this would be the package postgresql-contrib-9.1
- for PostgreSQL 9.1, obviously. Since Postgres 10, there is just a postgresql-contrib
metapackage.
CREATE EVENT test_event_03
ON SCHEDULE EVERY 1 MINUTE
STARTS CURRENT_TIMESTAMP
ENDS CURRENT_TIMESTAMP + INTERVAL 1 HOUR
DO
INSERT INTO messages(message,created_at)
VALUES('Test MySQL recurring Event',NOW());
Contacts.add(objt.Data(name, address, contact));
This is not a perfect way to call a constructor. The constructor is called at the time of object creation automatically. If there is no constructor java class creates its own constructor.
The correct way is:
// object creation.
Data object1 = new Data(name, address, contact);
// adding Data object to ArrayList object Contacts.
Contacts.add(object1);
Combining a couple answers above:
function isVisible (ele) {
var style = window.getComputedStyle(ele);
return style.width !== "0" &&
style.height !== "0" &&
style.opacity !== "0" &&
style.display!=='none' &&
style.visibility!== 'hidden';
}
Like AlexZ said, this may be slower than some of your other options if you know more specifically what you're looking for, but this should catch all of the main ways elements are hidden.
But, it also depends what counts as visible for you. Just for example, a div's height can be set to 0px but the contents still visible depending on the overflow properties. Or a div's contents could be made the same color as the background so it is not visible to users but still rendered on the page. Or a div could be moved off screen or hidden behind other divs, or it's contents could be non-visible but the border still visible. To a certain extent "visible" is a subjective term.
Another alternative (15. gets typed to [timespan] automatically):
ls -file | where { (get-date) - $_.creationtime -gt 15. } | Remove-Item -Verbose
Other than what Alex and Evan have already stated, I would like to add that a C++ struct is not like a C struct.
In C++, a struct can have methods, inheritance, etc. just like a C++ class.
You have a date with a known timezone (Here Europe/Madrid
), and a target timezone (UTC
)
You just need two SimpleDateFormats:
long ts = System.currentTimeMillis(); Date localTime = new Date(ts); SimpleDateFormat sdfLocal = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss"); sdfLocal.setTimeZone(TimeZone.getTimeZone("Europe/Madrid")); SimpleDateFormat sdfUTC = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss"); sdfUTC.setTimeZone(TimeZone.getTimeZone("UTC")); // Convert Local Time to UTC Date utcTime = sdfLocal.parse(sdfUTC.format(localTime)); System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:" + utcTime.toString() + "-" + utcTime.getTime()); // Reverse Convert UTC Time to Locale time localTime = sdfUTC.parse(sdfLocal.format(utcTime)); System.out.println("UTC:" + utcTime.toString() + "," + utcTime.getTime() + " --> Local time:" + localTime.toString() + "-" + localTime.getTime());
So after see it working you can add this method to your utils:
public Date convertDate(Date dateFrom, String fromTimeZone, String toTimeZone) throws ParseException { String pattern = "yyyy/MM/dd HH:mm:ss"; SimpleDateFormat sdfFrom = new SimpleDateFormat (pattern); sdfFrom.setTimeZone(TimeZone.getTimeZone(fromTimeZone)); SimpleDateFormat sdfTo = new SimpleDateFormat (pattern); sdfTo.setTimeZone(TimeZone.getTimeZone(toTimeZone)); Date dateTo = sdfFrom.parse(sdfTo.format(dateFrom)); return dateTo; }
Edit: thanks to @superlogical, you can now find and improve the following code in github!
I wrote this class based on some ideas here. The columns width is optimal, an it can handle object arrays with this simple API:
static void Main(string[] args)
{
IEnumerable<Tuple<int, string, string>> authors =
new[]
{
Tuple.Create(1, "Isaac", "Asimov"),
Tuple.Create(2, "Robert", "Heinlein"),
Tuple.Create(3, "Frank", "Herbert"),
Tuple.Create(4, "Aldous", "Huxley"),
};
Console.WriteLine(authors.ToStringTable(
new[] {"Id", "First Name", "Surname"},
a => a.Item1, a => a.Item2, a => a.Item3));
/* Result:
| Id | First Name | Surname |
|----------------------------|
| 1 | Isaac | Asimov |
| 2 | Robert | Heinlein |
| 3 | Frank | Herbert |
| 4 | Aldous | Huxley |
*/
}
Here is the class:
public static class TableParser
{
public static string ToStringTable<T>(
this IEnumerable<T> values,
string[] columnHeaders,
params Func<T, object>[] valueSelectors)
{
return ToStringTable(values.ToArray(), columnHeaders, valueSelectors);
}
public static string ToStringTable<T>(
this T[] values,
string[] columnHeaders,
params Func<T, object>[] valueSelectors)
{
Debug.Assert(columnHeaders.Length == valueSelectors.Length);
var arrValues = new string[values.Length + 1, valueSelectors.Length];
// Fill headers
for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
{
arrValues[0, colIndex] = columnHeaders[colIndex];
}
// Fill table rows
for (int rowIndex = 1; rowIndex < arrValues.GetLength(0); rowIndex++)
{
for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
{
arrValues[rowIndex, colIndex] = valueSelectors[colIndex]
.Invoke(values[rowIndex - 1]).ToString();
}
}
return ToStringTable(arrValues);
}
public static string ToStringTable(this string[,] arrValues)
{
int[] maxColumnsWidth = GetMaxColumnsWidth(arrValues);
var headerSpliter = new string('-', maxColumnsWidth.Sum(i => i + 3) - 1);
var sb = new StringBuilder();
for (int rowIndex = 0; rowIndex < arrValues.GetLength(0); rowIndex++)
{
for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
{
// Print cell
string cell = arrValues[rowIndex, colIndex];
cell = cell.PadRight(maxColumnsWidth[colIndex]);
sb.Append(" | ");
sb.Append(cell);
}
// Print end of line
sb.Append(" | ");
sb.AppendLine();
// Print splitter
if (rowIndex == 0)
{
sb.AppendFormat(" |{0}| ", headerSpliter);
sb.AppendLine();
}
}
return sb.ToString();
}
private static int[] GetMaxColumnsWidth(string[,] arrValues)
{
var maxColumnsWidth = new int[arrValues.GetLength(1)];
for (int colIndex = 0; colIndex < arrValues.GetLength(1); colIndex++)
{
for (int rowIndex = 0; rowIndex < arrValues.GetLength(0); rowIndex++)
{
int newLength = arrValues[rowIndex, colIndex].Length;
int oldLength = maxColumnsWidth[colIndex];
if (newLength > oldLength)
{
maxColumnsWidth[colIndex] = newLength;
}
}
}
return maxColumnsWidth;
}
}
Edit: I added a minor improvement - if you want the column headers to be the property name, add the following method to TableParser
(note that it will be a bit slower due to reflection):
public static string ToStringTable<T>(
this IEnumerable<T> values,
params Expression<Func<T, object>>[] valueSelectors)
{
var headers = valueSelectors.Select(func => GetProperty(func).Name).ToArray();
var selectors = valueSelectors.Select(exp => exp.Compile()).ToArray();
return ToStringTable(values, headers, selectors);
}
private static PropertyInfo GetProperty<T>(Expression<Func<T, object>> expresstion)
{
if (expresstion.Body is UnaryExpression)
{
if ((expresstion.Body as UnaryExpression).Operand is MemberExpression)
{
return ((expresstion.Body as UnaryExpression).Operand as MemberExpression).Member as PropertyInfo;
}
}
if ((expresstion.Body is MemberExpression))
{
return (expresstion.Body as MemberExpression).Member as PropertyInfo;
}
return null;
}
I was missing modal-dialog
that's why my close modal wasn't working properly.
There are a couple of options. You can use the --device
flag that use can use to access USB devices without --privileged
mode:
docker run -t -i --device=/dev/ttyUSB0 ubuntu bash
Alternatively, assuming your USB device is available with drivers working, etc. on the host in /dev/bus/usb
, you can mount this in the container using privileged mode and the volumes option. For example:
docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb ubuntu bash
Note that as the name implies, --privileged
is insecure and should be handled with care.
The command for commiting all changed files:
git commit -a -m 'My commit comments'
-a
= all edited files
-m
= following string is a comment.
This will commit to your local drives / folders repo. If you want to push your changes to a git server / remotely hosted server, after the above command type:
git push
GitHub's cheat sheet is quite handy.
You can use regular grep like this:
tail -f admin.log | grep -v "Nopaging the limit is\|keyword to remove is"

You can resize and then use imagejpeg()
Don't pass 100 as the quality for imagejpeg() - anything over 90 is generally overkill and just gets you a bigger JPEG. For a thumbnail, try 75 and work downwards until the quality/size tradeoff is acceptable.
imagejpeg($tn, $save, 75);

N-tier data applications are data applications that are separated into multiple tiers. Also called "distributed applications" and "multitier applications," n-tier applications separate processing into discrete tiers that are distributed between the client and the server. When you develop applications that access data, you should have a clear separation between the various tiers that make up the application.

HTML5 spec:
http://www.w3.org/TR/html5/forms.html#enabling-and-disabling-form-controls:-the-disabled-attribute :
The checked content attribute is a boolean attribute
http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes :
The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.
If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.
Conclusion:
The following are valid, equivalent and true:
<input type="text" disabled />
<input type="text" disabled="" />
<input type="text" disabled="disabled" />
<input type="text" disabled="DiSaBlEd" />
The following are invalid:
<input type="text" disabled="0" />
<input type="text" disabled="1" />
<input type="text" disabled="false" />
<input type="text" disabled="true" />
The absence of the attribute is the only valid syntax for false:
<input type="text" />
Recommendation
If you care about writing valid XHTML, use disabled="disabled"
, since <input disabled>
is invalid and other alternatives are less readable. Else, just use <input disabled>
as it is shorter.
You could try the "Microsoft Date and Time Picker Control". To use it, in the Toolbox, you right-click and choose "Additional Controls...". Then you check "Microsoft Date and Time Picker Control 6.0" and OK. You will have a new control in the Toolbox to do what you need.
I just found some printscreen of this on : http://www.logicwurks.com/CodeExamplePages/EDatePickerControl.html Forget the procedures, just check the printscreens.
Differences between
isinstance()
andtype()
in Python?
Type-checking with
isinstance(obj, Base)
allows for instances of subclasses and multiple possible bases:
isinstance(obj, (Base1, Base2))
whereas type-checking with
type(obj) is Base
only supports the type referenced.
As a sidenote, is
is likely more appropriate than
type(obj) == Base
because classes are singletons.
In Python, usually you want to allow any type for your arguments, treat it as expected, and if the object doesn't behave as expected, it will raise an appropriate error. This is known as polymorphism, also known as duck-typing.
def function_of_duck(duck):
duck.quack()
duck.swim()
If the code above works, we can presume our argument is a duck. Thus we can pass in other things are actual sub-types of duck:
function_of_duck(mallard)
or that work like a duck:
function_of_duck(object_that_quacks_and_swims_like_a_duck)
and our code still works.
However, there are some cases where it is desirable to explicitly type-check. Perhaps you have sensible things to do with different object types. For example, the Pandas Dataframe object can be constructed from dicts or records. In such a case, your code needs to know what type of argument it is getting so that it can properly handle it.
So, to answer the question:
isinstance()
and type()
in Python?Allow me to demonstrate the difference:
type
Say you need to ensure a certain behavior if your function gets a certain kind of argument (a common use-case for constructors). If you check for type like this:
def foo(data):
'''accepts a dict to construct something, string support in future'''
if type(data) is not dict:
# we're only going to test for dicts for now
raise ValueError('only dicts are supported for now')
If we try to pass in a dict that is a subclass of dict
(as we should be able to, if we're expecting our code to follow the principle of Liskov Substitution, that subtypes can be substituted for types) our code breaks!:
from collections import OrderedDict
foo(OrderedDict([('foo', 'bar'), ('fizz', 'buzz')]))
raises an error!
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in foo
ValueError: argument must be a dict
isinstance
But if we use isinstance
, we can support Liskov Substitution!:
def foo(a_dict):
if not isinstance(a_dict, dict):
raise ValueError('argument must be a dict')
return a_dict
foo(OrderedDict([('foo', 'bar'), ('fizz', 'buzz')]))
returns OrderedDict([('foo', 'bar'), ('fizz', 'buzz')])
In fact, we can do even better. collections
provides Abstract Base Classes that enforce minimal protocols for various types. In our case, if we only expect the Mapping
protocol, we can do the following, and our code becomes even more flexible:
from collections import Mapping
def foo(a_dict):
if not isinstance(a_dict, Mapping):
raise ValueError('argument must be a dict')
return a_dict
It should be noted that type can be used to check against multiple classes using
type(obj) in (A, B, C)
Yes, you can test for equality of types, but instead of the above, use the multiple bases for control flow, unless you are specifically only allowing those types:
isinstance(obj, (A, B, C))
The difference, again, is that isinstance
supports subclasses that can be substituted for the parent without otherwise breaking the program, a property known as Liskov substitution.
Even better, though, invert your dependencies and don't check for specific types at all.
So since we want to support substituting subclasses, in most cases, we want to avoid type-checking with type
and prefer type-checking with isinstance
- unless you really need to know the precise class of an instance.

buttonAre you testing this in local files or off a Web server? Files in different directories are considered different domains for cross-domain rules, so if you're testing locally you could be hitting cross-domain restrictions.
Otherwise, it would probably help to be pointed to a URL where the problem occurs.
Also, I'd suggest looking at the Firefox error console to see if any CSS syntax errors or other errors are reported.
Also, I'd note you probably want font-weight:bold in the second @font-face rule.

<h1>Sticky styles for better touch screen buttons!</h1>
<button>Normal button</button>
<button class="delayed"><a href="https://www.google.com"/>Delayed style</a></button>
<p>The CSS :active psuedo style is displayed between the time when a user touches down (when finger contacts screen) on a element to the time when the touch up (when finger leaves the screen) occures. With a typical touch-screen tap interaction, the time of which the :active psuedo style is displayed can be very small resulting in the :active state not showing or being missed by the user entirely. This can cause issues with users not undertanding if their button presses have actually reigstered or not.</p>
<p>Having the the :active styling stick around for a few hundred more milliseconds after touch up would would improve user understanding when they have interacted with a button.</p>

As stated, all objects in sharepoint contain some sort of unique identifier (often an integer based counter for list items, and GUIDs for lists).
That said, there is also a feature available at http://www.codeplex.com/features called "Unique Column Policy", designed to add an other column with a unique value. A complete writeup is available at http://scothillier.spaces.live.com/blog/cns!8F5DEA8AEA9E6FBB!293.entry
In addition to the existing answer it is possible to set a default option as follows:

Probably, contents of the JAR files in your local .m2 repository are HTML saying "301 Moved Permanently". It seems that mvn does not handle "301 Moved Permanently" properly as expected. In such a case, download the JAR files manually from somewhere (the central repository, for example) and put them into your .m2 repository.

Do you mean the conversion 011001100110111101101111
? foo
, for example? You just take the binary stream, split it into separate bytes (01100110
, 01101111
, 01101111
) and look up the ASCII character that corresponds to given number. For example, 01100110
is 102 in decimal and the ASCII character with code 102 is f
:
$ perl -E 'say 0b01100110'
102
$ perl -E 'say chr(102)'
f
(See what the chr
function does.) You can generalize this algorithm and have a different number of bits per character and different encodings, the point remains the same.
For MongoDB 3.6 and newer:
The $expr
operator allows the use of aggregation expressions within the query language, thus you can leverage the use of $strLenCP
operator to check the length of the string as follows:
db.usercollection.find({
"name": { "$exists": true },
"$expr": { "$gt": [ { "$strLenCP": "$name" }, 40 ] }
})
For MongoDB 3.4 and newer:
You can also use the aggregation framework with the $redact
pipeline operator that allows you to proccess the logical condition with the $cond
operator and uses the special operations $$KEEP
to "keep" the document where the logical condition is true or $$PRUNE
to "remove" the document where the condition was false.
This operation is similar to having a $project
pipeline that selects the fields in the collection and creates a new field that holds the result from the logical condition query and then a subsequent $match
, except that $redact
uses a single pipeline stage which is more efficient.
As for the logical condition, there are String Aggregation Operators that you can use $strLenCP
operator to check the length of the string. If the length is $gt
a specified value, then this is a true match and the document is "kept". Otherwise it is "pruned" and discarded.
Consider running the following aggregate operation which demonstrates the above concept:
db.usercollection.aggregate([
{ "$match": { "name": { "$exists": true } } },
{
"$redact": {
"$cond": [
{ "$gt": [ { "$strLenCP": "$name" }, 40] },
"$$KEEP",
"$$PRUNE"
]
}
},
{ "$limit": 2 }
])
If using $where
, try your query without the enclosing brackets:
db.usercollection.find({$where: "this.name.length > 40"}).limit(2);
A better query would be to to check for the field's existence and then check the length:
db.usercollection.find({name: {$type: 2}, $where: "this.name.length > 40"}).limit(2);
or:
db.usercollection.find({name: {$exists: true}, $where: "this.name.length >
40"}).limit(2);
MongoDB evaluates non-$where
query operations before $where
expressions and non-$where
query statements may use an index. A much better performance is to store the length of the string as another field and then you can index or search on it; applying $where
will be much slower compared to that. It's recommended to use JavaScript expressions and the $where
operator as a last resort when you can't structure the data in any other way, or when you are dealing with a
small subset of data.
A different and faster approach that avoids the use of the $where
operator is the $regex
operator. Consider the following pattern which searches for
db.usercollection.find({"name": {"$type": 2, "$regex": /^.{41,}$/}}).limit(2);
Note - From the docs:
If an index exists for the field, then MongoDB matches the regular expression against the values in the index, which can be faster than a collection scan. Further optimization can occur if the regular expression is a “prefix expression”, which means that all potential matches start with the same string. This allows MongoDB to construct a “range” from that prefix and only match against those values from the index that fall within that range.
A regular expression is a “prefix expression” if it starts with a caret
(^)
or a left anchor(\A)
, followed by a string of simple symbols. For example, the regex/^abc.*/
will be optimized by matching only against the values from the index that start withabc
.Additionally, while
/^a/, /^a.*/,
and/^a.*$/
match equivalent strings, they have different performance characteristics. All of these expressions use an index if an appropriate index exists; however,/^a.*/
, and/^a.*$/
are slower./^a/
can stop scanning after matching the prefix.
A File object in Java is a representation of a path to a directory or file, not the file itself. You don't need to have write access to the filesystem to create a File
object, you only need it if you intend to actually write to the file (using a FileOutputStream for example)
SCRUM :
SCRUM is a type of Agile approach. It is a Framework not a Methodology.
It does not provide detailed instructions to what needs to be done rather most of it is dependent on the team that is developing the software. Because the developing the project knows how the problem can be solved that is why much is left on them
Cross-functional and self-organizing teams are essential in case of scrum. There is no team leader in this case who will assign tasks to the team members rather the whole team addresses the issues or problems. It is cross-functional in a way that everyone is involved in the project right from the idea to the implementation of the project.
The advantage of scrum is that a project’s direction to be adjusted based on completed work, not on speculation or predictions.
Roles Involved : Product Owner, Scrum Master, Team Members
Agile Methodology :
Build Software applications that are unpredictable in nature
Iterative and incremental work cadences called sprints are used in this methodology.
Both Agile and SCRUM follows the system -- some of the features are developed as a part of the sprint and at the end of each sprint; the features are completed right from coding, testing and their integration into the product. A demonstration of the functionality is provided to the owner at the end of each sprint so that feedback can be taken which can be helpful for the next sprint.
Manifesto for Agile Development :
That is, while there is value in the items on the right, we value the items on the left more.
Found the solution after some searching.
You need to add a <meta>
tag in your <head>
containing name="theme-color"
, with your HEX code as the content value. For example:
<meta name="theme-color" content="#999999" />
If the android device has native dark-mode
enabled, then this meta
tag is ignored.
Chrome for Android does not use the color on devices with native
dark-mode
enabled.
Just store the index generated in a variable, and then access the array using this varaible:
int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);
P.S. I usually don't like generating new Random
object per randoization - I prefer using a single Random
in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.
According to this approach, I will have some variable Random r
somewhere, and I will just use:
int idx = r.nextInt(fruits.length)
However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.
To change the disabled
property you should use the .prop()
function.
$("input").prop('disabled', true);
$("input").prop('disabled', false);
The .prop()
function doesn't exist, but .attr()
does similar:
Set the disabled attribute.
$("input").attr('disabled','disabled');
To enable again, the proper method is to use .removeAttr()
$("input").removeAttr('disabled');
You can always rely on the actual DOM object and is probably a little faster than the other two options if you are only dealing with one element:
// assuming an event handler thus 'this'
this.disabled = true;
The advantage to using the .prop()
or .attr()
methods is that you can set the property for a bunch of selected items.
Note: In 1.6 there is a .removeProp()
method that sounds a lot like removeAttr()
, but it SHOULD NOT BE USED on native properties like 'disabled'
Excerpt from the documentation:
Note: Do not use this method to remove native properties such as checked, disabled, or selected. This will remove the property completely and, once removed, cannot be added again to element. Use .prop() to set these properties to false instead.
In fact, I doubt there are many legitimate uses for this method, boolean props are done in such a way that you should set them to false instead of "removing" them like their "attribute" counterparts in 1.5
In my case, I found that placing a here document (like sqplus ... << EOF) statements indented also raise the same error as shown below:
./dbuser_case.ksh: line 25: syntax error: unexpected end of file
So after removing the indentation for this, then it went fine.
Hope it helps...
These preferences appear to have changed since @alex-dima's answer.
Changing settings
From menu choose: File -> Preferences -> Settings -> User/Workspace Settings. Filter default settings to search
.
You can modify the search.exclude
setting (copy from default setting to your user or workspace settings). That will apply only to searches. Note that settings from files.exclude
will be automatically applied.
If the settings don't work:
Make sure you didn't turn the search exclusion off. In the search area, expand the "files to exclude" input box and make sure that the gear icon is selected.
You might also need to Clear Editor History (See: https://github.com/Microsoft/vscode/issues/6502).
Example settings
For example, I am developing an EmberJS application which saves thousands of files under the tmp directory.
If you select WORKSPACE SETTINGS
on the right side of the search field, the search exclusion will only be applied to this particular project. And a corresponding .vscode
folder will be added to the root folder containing settings.json
.
This is my example settings:
{
// ...
"search.exclude": {
"**/.git": true,
"**/node_modules": true,
"**/bower_components": true,
"**/tmp": true
},
// ...
}
Note: Include a ** at the beginning of any search exclusion to cover the search term over any folders and sub-folders.

Also You Can Use Server.Execute
You get a recursion error because your attempt to access the self.__dict__
attribute inside __getattribute__
invokes your __getattribute__
again. If you use object
's __getattribute__
instead, it works:
class D(object):
def __init__(self):
self.test=20
self.test2=21
def __getattribute__(self,name):
if name=='test':
return 0.
else:
return object.__getattribute__(self, name)
This works because object
(in this example) is the base class. By calling the base version of __getattribute__
you avoid the recursive hell you were in before.

Update:
There's something in the section titled More attribute access for new-style classes in the current documentation, where they recommend doing exactly this to avoid the infinite recursion.

target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

try {

Yes to the loop (either using indexes or an Iterator
). On the return value, either return its index, or the item iteself, depending on your needs. ArrayList
doesn't have an indexOf
(Object target, Comparator compare)` or similar. Now that Java is getting lambda expressions (in Java 8, ~March 2014), I expect we'll see APIs get methods that accept lambdas for things like this.
using css we can adjust specific column width which i put in below code.

An oblique answer to the question is to write all the code as classes, apart from the index.php files, which are then the only points of entry. PHP files that contain classes will not cause anything to happen, even if they are invoked directly through Apache.
A direct answer is to include the following in .htaccess:
<FilesMatch "\.php$">
Order Allow,Deny
Deny from all
</FilesMatch>
<FilesMatch "index[0-9]?\.php$">
Order Allow,Deny
Allow from all
</FilesMatch>
This will allow any file like index.php, index2.php etc to be accessed, but will refuse access of any kind to other .php files. It will not affect other file types.
Can you try this,
echo date("Y-m-d H:i:s", 1388516401);
As noted by theGame,
This means that you pass in a string value for the time, and optionally a value for the current time, which is a UNIX timestamp. The value that is returned is an integer which is a UNIX timestamp.
echo strtotime("2014-01-01 00:00:01");
This will return into the value 1388516401, which is the UNIX timestamp for the date 2014-01-01. This can be confirmed using the date() function as like below:
echo date('Y-m-d', 1198148400); // echos 2014-01-01

I'm surprised no one has mentioned Microsoft's ildasm. It may not be as pretty as ILSpy or Reflector, but it comes with Visual Studio so many developers already have it.
To run it (assuming VS 2013, should be similar for other versions):
Now you can navigate the DLL structure. Double-click on class members to see the IL. Use File > Dump to export IL to a file.
Hyperlink
is not a control, it is a flow content element, you can only use it in controls which support flow content, like a TextBlock
. TextBoxes
only have plain text.
You can do it best in one pass.
largest and largest2 are set to INT_MIN on entry. Then step through the array. If largest is smaller than the number, largest2 becomes largest, then largest becomes the new number (or smaller than or equal if you want to allow duplicates). If largest is greater then the new number, test largest2.
Note that this algorithm scales to finding the top three or four in an array, before it become too cumbersome and it's better to just sort.
To delete all the files inside the directory as well as its sub-directories, without removing the folders themselves, simply do this:
import os
mypath = "my_folder" #Enter your path here
for root, dirs, files in os.walk(mypath):
for file in files:
os.remove(os.path.join(root, file))
import warnings
warnings.warn("Warning...........Message")
See the python documentation: here

After trying EVERY solution google came up with on stack overflow, I found what my particular problem was. I had edited my hosts file a long time ago to allow me to access my localhost from my virtualbox.
Removing this entry solved it for me, along with the correct installation of mongoDB from the link given in the above solution, and including the correct promise handling code:
mongoose.connect('mongodb://localhost/testdb').then(() => {
console.log("Connected to Database");
}).catch((err) => {
console.log("Not Connected to Database ERROR! ", err);
});
Correct Solution is this
- (void)viewDidLoad
{
[super viewDidLoad];
[self.tableView registerNib:[UINib nibWithNibName:@"CustomCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:@"CustomCell"];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"CustomCell"];
return cell;
}
It's worth noting that multiple field indexes can drastically improve your query performance. So in the above example we assume ProductID is the only field to lookup but were the query to say ProductID = 1 AND Category = 7 then a multiple column index helps. This is achieved with the following:
ALTER TABLE `table` ADD INDEX `index_name` (`col1`,`col2`)
Additionally the index should match the order of the query fields. In my extended example the index should be (ProductID,Category) not the other way around.

Removing the outline is an accessibility nightmare. People tabbing using keyboards will never know what item they're on.
Best to leave it, as most clicked buttons will take you somewhere anyway, or if you HAVE to remove the outline then isolate it a specific class name.
.no-outline {
outline: none;
}
Then you can apply that class whenever you need to.
I see the question has been answered to a general standard, but when I looked at your site I noticed there is still a horizontal scroll-bar. I also notice the reason for this: You have used the code:
.homepageconference .container {
padding-left: 12%;
}
which is being used alongside code stating that the element has a width of 100%, causing an element with a total width of 112% of screen size. To fix this, either remove the padding, replace the padding with a margin of 12% for the same effect, or change the width (or max-width) of the element to 88%. This occurs in main.css at line 343. Hope this helps!
Here is my approach:
>>> import os
>>> print os.path.basename(
os.path.dirname('/folderA/folderB/folderC/folderD/test.py'))
folderD
>>> print os.path.basename(
os.path.dirname('/folderA/folderB/folderC/folderD/'))
folderD
>>> print os.path.basename(
os.path.dirname('/folderA/folderB/folderC/folderD'))
folderC
A nice and clean solution, that doesn't require any external dependencies:
It uses a custom plus the useEffect React hooks and the setTimeout
/ clearTimeout
method.
If you want to remove specific punctuation from a string, it will probably be best to explicitly remove exactly what you want like
replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"")
Doing the above still doesn't return the string as you have specified it. If you want to remove any extra spaces that were left over from removing crazy punctuation, then you are going to want to do something like
replace(/\s{2,}/g," ");
My full example:
var s = "This., -/ is #! an $ % ^ & * example ;: {} of a = -_ string with `~)() punctuation";
var punctuationless = s.replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"");
var finalString = punctuationless.replace(/\s{2,}/g," ");
Results of running code in firebug console:
I know this is an old question but it does not yet appear to have an answer. I've duplicated this situation, but I'm writing the server app, so I've been able to establish what happens on the server side as well. The client sends the certificate when the server asks for it and if it has a reference to a real certificate in the s_client command line. My server application is set up to ask for a client certificate and to fail if one is not presented. Here is the command line I issue:
Yourhostname here -vvvvvvvvvv
s_client -connect <hostname>:443 -cert client.pem -key cckey.pem -CAfile rootcert.pem -cipher ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH -tls1 -state
When I leave out the "-cert client.pem" part of the command the handshake fails on the server side and the s_client command fails with an error reported. I still get the report "No client certificate CA names sent" but I think that has been answered here above.
The short answer then is that the server determines whether a certificate will be sent by the client under normal operating conditions (s_client is not normal) and the failure is due to the server not recognizing the CA in the certificate presented. I'm not familiar with many situations in which two-way authentication is done although it is required for my project.
You are clearly sending a certificate. The server is clearly rejecting it.
The missing information here is the exact manner in which the certs were created and the way in which the provider loaded the cert, but that is probably all wrapped up by now.
A version that handles nested dictionaries and iterables but does not use the json
module. Nested dictionaries become dict
, nested iterables become list
, everything else is returned unchanged (including dictionary keys and strings/bytes/bytearrays).
def recursive_to_dict(obj):
try:
if hasattr(obj, "split"): # is string-like
return obj
elif hasattr(obj, "items"): # is dict-like
return {k: recursive_to_dict(v) for k, v in obj.items()}
else: # is iterable
return [recursive_to_dict(e) for e in obj]
except TypeError: # return everything else
return obj
Taking what I feel are the best aspects of the previous examples, here's what I came up with:
class Struct:
'''The recursive class for building and representing objects with.'''
def __init__(self, obj):
for k, v in obj.iteritems():
if isinstance(v, dict):
setattr(self, k, Struct(v))
else:
setattr(self, k, v)
def __getitem__(self, val):
return self.__dict__[val]
def __repr__(self):
return '{%s}' % str(', '.join('%s : %s' % (k, repr(v)) for
(k, v) in self.__dict__.iteritems()))

It always depends on what you need.
You should use operator[]
when you need direct access to elements in the vector (when you need to index a specific element in the vector). There is nothing wrong in using it over iterators. However, you must decide for yourself which (operator[]
or iterators) suits best your needs.
Using iterators would enable you to switch to other container types without much change in your code. In other words, using iterators would make your code more generic, and does not depend on a particular type of container.
I don't know what the "preferred" method is (ask 100 people and get 100 different opinions) but do what's simplest and what works. GetName
works but requires a lot more keystrokes. ToString()
seems to do the job very well.
First, what you are looking for is a column or bar diagram, not really a histogram. A histogram is made from a frequency distribution of a continuous variable that is separated into bins. Here you have a column against separate labels.
To make a bar diagram with matplotlib, use the matplotlib.pyplot.bar()
method. Have a look at this page of the matplotlib documentation that explains very well with examples and source code how to do it.
If it is possible though, I would just suggest that for a simple task like this if you could avoid writing code that would be better. If you have any spreadsheet program this should be a piece of cake because that's exactly what they are for, and you won't have to 'reinvent the wheel'. The following is the plot of your data in Excel:
I just copied your data from the question, used the text import wizard to put it in two columns, then I inserted a column diagram.

It's not ideal, but you could disable Jackson's auto-discovery of JSON properties, using @JsonAutoDetect
at the class level. This would prevent it from trying to handle the Javassist stuff (and failing).
This means that you then have to annotate each getter manually (with @JsonProperty
), but that's not necessarily a bad thing, since it keeps things explicit.

Hi i wrote this general function to generate a dummy variable which essentially replicates the replace function in Stata.
If x is the data frame is x and i want a dummy variable called a
which will take value 1
when x$b
takes value c
introducedummy<-function(x,a,b,c){
g<-c(a,b,c)
n<-nrow(x)
newcol<-g[1]
p<-colnames(x)
p2<-c(p,newcol)
new1<-numeric(n)
state<-x[,g[2]]
interest<-g[3]
for(i in 1:n){
if(state[i]==interest){
new1[i]=1
}
else{
new1[i]=0
}
}
x$added<-new1
colnames(x)<-p2
x
}
For completeness sake the reverse function:
function a2hex(str) {
var arr = [];
for (var i = 0, l = str.length; i < l; i ++) {
var hex = Number(str.charCodeAt(i)).toString(16);
arr.push(hex);
}
return arr.join('');
}
a2hex('2460'); //returns 32343630
I copied and pasted your script into a .py file. I ran it as-is with Python 2.7.10 and received the same syntax error. I also tried the script in Python 3.5 and received the following output:
File "print_strings_on_same_line.py", line 16
print fiveYears
^
SyntaxError: Missing parentheses in call to 'print'
Then, I modified the last line where it prints the number of births as follows:
currentPop = 312032486
oneYear = 365
hours = 24
minutes = 60
seconds = 60
# seconds in a single day
secondsInDay = hours * minutes * seconds
# seconds in a year
secondsInYear = secondsInDay * oneYear
fiveYears = secondsInYear * 5
#Seconds in 5 years
print fiveYears
# fiveYears in seconds, divided by 7 seconds
births = fiveYears // 7
print "If there was a birth every 7 seconds, there would be: " + str(births) + " births"
The output was (Python 2.7.10):
157680000
If there was a birth every 7 seconds, there would be: 22525714 births
I hope this helps.
For any given number:
n = num;
rev = 0;
while (num > 0)
{
dig = num % 10;
rev = rev * 10 + dig;
num = num / 10;
}
If n == rev
then num
is a palindrome:
cout << "Number " << (n == rev ? "IS" : "IS NOT") << " a palindrome" << endl;
Since this answer isn't here yet, just wanted to point out you can also use the infoDictionary property to get the info plist as a dictionary, Bundle.main.infoDictionary
.
Although something like Bundle.main.object(forInfoDictionaryKey: kCFBundleNameKey as String)
may be faster if you're only interested in a specific item in the info plist.
// Swift 4
// Getting info plist as a dictionary
let dictionary = Bundle.main.infoDictionary
// Getting the app display name from the info plist
Bundle.main.infoDictionary?[kCFBundleNameKey as String]
// Getting the app display name from the info plist (another way)
Bundle.main.object(forInfoDictionaryKey: kCFBundleNameKey as String)

This is relatively simple if you use pylab (included with matplotlib) instead of matplotlib directly. Start off with a list of filenames and legend names, like [ ('name of file 1', 'label 1'), ('name of file 2', 'label 2'), ...]. Then you can use something like the following:
import pylab
datalist = [ ( pylab.loadtxt(filename), label ) for filename, label in list_of_files ]
for data, label in datalist:
pylab.plot( data[:,0], data[:,1], label=label )
pylab.legend()
pylab.title("Title of Plot")
pylab.xlabel("X Axis Label")
pylab.ylabel("Y Axis Label")
You also might want to add something like fmt='o' to the plot command, in order to change from a line to points. By default, matplotlib with pylab plots onto the same figure without clearing it, so you can just run the plot command multiple times.

You can get idea from this.
jQuery has a toggleClass function:
<button class="switch">Click me</button>
<div class="text-block collapsed pressed">some text</div>
<script>
$('.switch').on('click', function(e) {
$('.text-block').toggleClass("collapsed pressed"); //you can list several class names
e.preventDefault();
});
</script>
The recommended approach in this case is to sort the data in the database, adding an ORDER BY
at the end of the query that fetches the results, something like this:
SELECT temperature FROM temperatures ORDER BY temperature ASC; -- ascending order
SELECT temperature FROM temperatures ORDER BY temperature DESC; -- descending order
If for some reason that is not an option, you can change the sorting order like this in Python:
templist = [25, 50, 100, 150, 200, 250, 300, 33]
sorted(templist, key=int) # ascending order
> [25, 33, 50, 100, 150, 200, 250, 300]
sorted(templist, key=int, reverse=True) # descending order
> [300, 250, 200, 150, 100, 50, 33, 25]
As has been pointed in the comments, the int
key (or float
if values with decimals are being stored) is required for correctly sorting the data if the data received is of type string
, but it'd be very strange to store temperature values as strings, if that is the case, go back and fix the problem at the root, and make sure that the temperatures being stored are numbers.
You can use split
to split the text.
As an alternative, you can also use match
as follow
var str = 'john smith~123 Street~Apt 4~New York~NY~12345';_x000D_
matches = str.match(/[^~]+/g);_x000D_
_x000D_
console.log(matches);_x000D_
document.write(matches);
_x000D_
The regex [^~]+
will match all the characters except ~
and return the matches in an array. You can then extract the matches from it.
The code below creates a Documents directory and then a sub-directory for the application and saved the files to it.
public class loadDataTooDisk extends AsyncTask<String, Integer, String> {
String sdCardFileTxt;
@Override
protected String doInBackground(String... params)
{
//check to see if external storage is avalibel
checkState();
if(canW == canR == true)
{
//get the path to sdcard
File pathToExternalStorage = Environment.getExternalStorageDirectory();
//to this path add a new directory path and create new App dir (InstroList) in /documents Dir
File appDirectory = new File(pathToExternalStorage.getAbsolutePath() + "/documents/InstroList");
// have the object build the directory structure, if needed.
appDirectory.mkdirs();
//test to see if it is a Text file
if ( myNewFileName.endsWith(".txt") )
{
//Create a File for the output file data
File saveFilePath = new File (appDirectory, myNewFileName);
//Adds the textbox data to the file
try{
String newline = "\r\n";
FileOutputStream fos = new FileOutputStream (saveFilePath);
OutputStreamWriter OutDataWriter = new OutputStreamWriter(fos);
OutDataWriter.write(equipNo.getText() + newline);
// OutDataWriter.append(equipNo.getText() + newline);
OutDataWriter.append(equip_Type.getText() + newline);
OutDataWriter.append(equip_Make.getText()+ newline);
OutDataWriter.append(equipModel_No.getText()+ newline);
OutDataWriter.append(equip_Password.getText()+ newline);
OutDataWriter.append(equipWeb_Site.getText()+ newline);
//OutDataWriter.append(equipNotes.getText());
OutDataWriter.close();
fos.flush();
fos.close();
}catch(Exception e){
e.printStackTrace();
}
}
}
return null;
}
}
This one builds the file name
private String BuildNewFileName()
{ // creates a new filr name
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();
StringBuilder sb = new StringBuilder();
sb.append(today.year + ""); // Year)
sb.append("_");
sb.append(today.monthDay + ""); // Day of the month (1-31)
sb.append("_");
sb.append(today.month + ""); // Month (0-11))
sb.append("_");
sb.append(today.format("%k:%M:%S")); // Current time
sb.append(".txt"); //Completed file name
myNewFileName = sb.toString();
//Replace (:) with (_)
myNewFileName = myNewFileName.replaceAll(":", "_");
return myNewFileName;
}
Hope this helps! It took me a long time to get it working.
edit (not by the author): There is a comprehensive list of IoC frameworks available at https://github.com/quozd/awesome-dotnet/blob/master/README.md#ioc:
Original answer follows.
I suppose I might be being a bit picky here but it's important to note that DI (Dependency Injection) is a programming pattern and is facilitated by, but does not require, an IoC (Inversion of Control) framework. IoC frameworks just make DI much easier and they provide a host of other benefits over and above DI.
That being said, I'm sure that's what you were asking. About IoC Frameworks; I used to use Spring.Net and CastleWindsor a lot, but the real pain in the behind was all that pesky XML config you had to write! They're pretty much all moving this way now, so I have been using StructureMap for the last year or so, and since it has moved to a fluent config using strongly typed generics and a registry, my pain barrier in using IoC has dropped to below zero! I get an absolute kick out of knowing now that my IoC config is checked at compile-time (for the most part) and I have had nothing but joy with StructureMap and its speed. I won't say that the others were slow at runtime, but they were more difficult for me to setup and frustration often won the day.
Update
I've been using Ninject on my latest project and it has been an absolute pleasure to use. Words fail me a bit here, but (as we say in the UK) this framework is 'the Dogs'. I would highly recommend it for any green fields projects where you want to be up and running quickly. I got all I needed from a fantastic set of Ninject screencasts by Justin Etheredge. I can't see that retro-fitting Ninject into existing code being a problem at all, but then the same could be said of StructureMap in my experience. It'll be a tough choice going forward between those two, but I'd rather have competition than stagnation and there's a decent amount of healthy competition out there.
Other IoC screencasts can also be found here on Dimecasts.
I seem to be able to get along with simply:
$gpg <path_to_file>
Which outputs like this:
$ gpg /tmp/keys/something.asc
pub 1024D/560C6C26 2014-11-26 Something <[email protected]>
sub 2048g/0C1ACCA6 2014-11-26
The op didn't specify in particular what key info is relevant. This output is all I care about.
The full error message sounds:
ERROR 1075 (42000): Incorrect table definition; there can be only one auto column and it must be defined as a key
So add primary key
to the auto_increment
field:
CREATE TABLE book (
id INT AUTO_INCREMENT primary key NOT NULL,
accepted_terms BIT(1) NOT NULL,
accepted_privacy BIT(1) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
See this link. It shows you how to dynamically create variables in PowerShell.
Here is the basic idea:
Use New-Variable and Get-Variable,
for ($i=1; $i -le 5; $i++)
{
New-Variable -Name "var$i" -Value $i
Get-Variable -Name "var$i" -ValueOnly
}
(It is taken from the link provided, and I don't take credit for the code.)
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
System.out.println(dateFormat.format(date));
found here
Your code is working just fine, you have to declare javscript method before DOM ready.
in addition, you can drop multiple partitions from one statement (Dropping multiple partitions in Impala/Hive).
Extract from above link:
hive> alter table t drop if exists partition (p=1),partition (p=2),partition(p=3);
Dropped the partition p=1
Dropped the partition p=2
Dropped the partition p=3
OK
EDIT 1:
Also, you can drop bulk using a condition sign (>,<,<>), for example:
Alter table t
drop partition (PART_COL>1);
Add line break to ::after
or ::before
pseudo-element content
.yourclass:before {
content: 'text here first \A text here second';
white-space: pre;
}
No, using sessions does not necessarily violate RESTfulness. If you adhere to the REST precepts and constraints, then using sessions - to maintain state - will simply be superfluous. After all, RESTfulness requires that the server not maintain state.
You have to loop through each element in the 2d-array, and get the nth column.
function getCol(matrix, col){
var column = [];
for(var i=0; i<matrix.length; i++){
column.push(matrix[i][col]);
}
return column;
}
var array = [new Array(20), new Array(20), new Array(20)]; //..your 3x20 array
getCol(array, 0); //Get first column
I worked on this same issue and I am sure I have found out the exact reason for it.

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.
However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.
Since you're accessing a web.config
you should probably use
using System.Web.Configuration;
WebConfigurationManager.AppSettings["configFile"]
Most of the answers suggest the Array.prototype.indexOf
method, the only problem is that it will not work on any IE version before IE9.
As an alternative I leave you two more options that will work on all browsers:
if (/Foo|Bar|Baz/.test(str)) {
// ...
}
if (str.match("Foo|Bar|Baz")) {
// ...
}
Try:
function is_numeric(str){
try {
return isFinite(str)
}
catch(err) {
return false
}
}
When you read in the year month day hour minutes with something like nextInt() it leaves rest of the line in the parser/buffer (even if it is blank) so when you call nextLine() you are reading the rest of this first line.
I suggest you call scan.nextLine() before you print your next prompt to discard the rest of the line.
if (($num >= $lower_boundary) && ($num <= $upper_boundary)) {
You may want to adjust the comparison operators if you want the boundary values not to be valid.
based on Wesley Coetzee's answer i wrote this. Hope it can help anyone googling this issue. I had bugs with swapping the paginator size in the middle of the list that's why i submit my answer:
Paginator html and list
<mat-paginator [length]="localNewspapers.length" pageSize=20
(page)="getPaginatorData($event)" [pageSizeOptions]="[10, 20, 30]"
showFirstLastButtons="false">
</mat-paginator>
<mat-list>
<app-newspaper-pagi-item *ngFor="let paper of (localNewspapers |
slice: lowValue : highValue)"
[newspaper]="paper">
</app-newspaper-pagi-item>
Component logic
import {Component, Input, OnInit} from "@angular/core";
import {PageEvent} from "@angular/material";
@Component({
selector: 'app-uniques-newspaper-list',
templateUrl: './newspaper-uniques-list.component.html',
})
export class NewspaperUniquesListComponent implements OnInit {
lowValue: number = 0;
highValue: number = 20;
// used to build an array of papers relevant at any given time
public getPaginatorData(event: PageEvent): PageEvent {
this.lowValue = event.pageIndex * event.pageSize;
this.highValue = this.lowValue + event.pageSize;
return event;
}
}
It should be quite simple if you are using LogBack or SLF4J. I do it as below
//imports
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
//Initialize logger
Logger logger = LoggerFactory.getLogger(<classname>.class);
try {
//try something
} catch(Exception e){
//Actual logging of error
logger.error("some message", e);
}
Just wanted to add a couple of pence to the excellent answers above: If you are working on pre Extjs 4.1, and don't have application wide events but need them, I've been using a very simple technique that might help: Create a simple object extending Observable, and define any app wide events you might need in it. You can then fire those events from anywhere in your app, including actual html dom element and listen to them from any component by relaying the required elements from that component.
Ext.define('Lib.MessageBus', {
extend: 'Ext.util.Observable',
constructor: function() {
this.addEvents(
/*
* describe the event
*/
"eventname"
);
this.callParent(arguments);
}
});
Then you can, from any other component:
this.relayEvents(MesageBus, ['event1', 'event2'])
And fire them from any component or dom element:
MessageBus.fireEvent('event1', somearg);
<input type="button onclick="MessageBus.fireEvent('event2', 'somearg')">
var arr = [1,2,3,4,5]
function avg(arr){
var sum = 0;
for (var i = 0; i < arr.length; i++) {
sum += parseFloat(arr[i])
}
return sum / i;
}
avg(arr) ======>>>> 3
This works with strings as numbers or numbers in the array.
For global functions you can use this one instead of eval
suggested in one of the answers.
var global = (function (){
return this;
})();
if (typeof(global.f) != "function")
global.f = function f1_shim (){
// commonly used by polyfill libs
};
You can use global.f instanceof Function
as well, but afaik. the value of the Function
will be different in different frames, so it will work only with a single frame application properly. That's why we usually use typeof
instead. Note that in some environments there can be anomalies with typeof f
too, e.g. by MSIE 6-8 some of the functions for example alert
had "object" type.
By local functions you can use the one in the accepted answer. You can test whether the function is local or global too.
if (typeof(f) == "function")
if (global.f === f)
console.log("f is a global function");
else
console.log("f is a local function");
To answer the question, the example code is working for me without error in latest browers, so I am not sure what was the problem with it:
function something_cool(text, callback) {
alert(text);
if( callback != null ) callback();
}
Note: I would use callback !== undefined
instead of callback != null
, but they do almost the same.
I had this challenge when working on MySQL Ver 8.0.21
I wanted to grant permissions of a database named my_app_db
to the root
user running on localhost
host.
But when I run the command:
use my_app_db;
GRANT ALL PRIVILEGES ON my_app_db.* TO 'root'@'localhost';
I get the error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'my_app_db.* TO 'root'@'localhost'' at line 1>
Here's how I fixed:
Login to your MySQL console. You can change root
to the user you want to login with:
mysql -u root -p
Enter your mysql root password
Next, list out all the users and their host on the MySQL server. Unlike PostgreSQL this is often stored in the mysql
database. So we need to select the mysql
database first:
use mysql;
SELECT user, host FROM user;
Note: if you don't run the use mysql
, you get the no database selected
error.
This should give you an output of this sort:
+------------------+-----------+
| user | host |
+------------------+-----------+
| mysql.infoschema | localhost |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+------------------+-----------+
4 rows in set (0.00 sec)
Next, based on the information gotten from the list, grant privileges to the user that you want. We will need to first select the database before granting permission to it. For me, I am using the root
user that runs on the localhost
host:
use my_app_db;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
Note: The GRANT ALL PRIVILEGES ON database_name.* TO 'root'@'localhost';
command may not work for modern versions of MySQL. Most modern versions of MyQL replace the database_name
with *
in the grant privileges command after you select the database that you want to use.
You can then exit the MySQL console:
exit
That's it.
I hope this helps
I had a similar issue where one of the arrays was modified. I was using it for $httpBackend
, and the returned object from that was actually a $promise
object containing the array (not an Array
object).
You can create a jasmine matcher to match the array by creating a toBeArray
function:
beforeEach(function() {
'use strict';
this.addMatchers({
toBeArray: function(array) {
this.message = function() {
return "Expected " + angular.mock.dump(this.actual) + " to be array " + angular.mock.dump(array) + ".";
};
var arraysAreSame = function(x, y) {
var arraysAreSame = true;
for(var i; i < x.length; i++)
if(x[i] !== y[i])
arraysAreSame = false;
return arraysAreSame;
};
return arraysAreSame(this.actual, array);
}
});
});
And then just use it in your tests like the other jasmine matchers:
it('should compare arrays properly', function() {
var array1, array2;
/* . . . */
expect(array1[0]).toBe(array2[0]);
expect(array1).toBeArray(array2);
});
If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:
plt.axes[0].get_lines()[0].set_color('black')
If you can avoid the need for concurrent writes to a single file, it sounds like you do not need a database to store the chat messages.
Just append the conversation to a text file (1 file per user\conversation). and have a directory/ file structure
Here's a simplified view of the file structure:
chat-1-bob.txt
201101011029, hi
201101011030, fine thanks.
chat-1-jen.txt
201101011030, how are you?
201101011035, have you spoken to bill recently?
chat-2-bob.txt
201101021200, hi
201101021222, about 12:22
chat-2-bill.txt
201101021201, Hey Bob,
201101021203, what time do you call this?
You would then only need to store the userid, conversation id (guid ?) & a reference to the file name.
I think you will find it hard to get a more simple scaleable solution.
You can use LOAD_FILE
to get the data too see: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html
If you have a requirement to rebuild a conversation you will need to put a value (date time) alongside your sent chat message (in the file) to allow you to merge & sort the files, but at this point it is probably a good idea to consider using a database.
You can just substract two date objects.
var d1 = new Date(); //"now"
var d2 = new Date("2011/02/01") // some date
var diff = Math.abs(d1-d2); // difference in milliseconds
You can use numpy.append()
to append a row to numpty array and reshape to a matrix later on.
import numpy as np
a = np.array([1,2])
a = np.append(a, [3,4])
print a
# [1,2,3,4]
# in your example
A = [1,2]
for row in X:
A = np.append(A, row)
Received SQLSTATE 01000 in the following error message below:
SQL Agent - Jobs Failed: The SQL Agent Job "LiteSpeed Backup Full" has failed with the message "The job failed. The Job was invoked by User X. The last step to run was step 1 (Step1). NOTE: Failed to notify via email. - Executed as user: X. LiteSpeed(R) for SQL Server Version 6.5.0.1460 Copyright 2011 Quest Software, Inc. [SQLSTATE 01000] (Message 1) LiteSpeed for SQL Server could not open backup file: (N:\BACKUP2\filename.BAK). The previous system message is the reason for the failure. [SQLSTATE 42000] (Error 60405). The step failed."
In my case this was related to permission on drive N following an SQL Server failover on an Active/Passive SQL cluster.
All SQL resources where failed over to the seconary resouce and back to the preferred node following maintenance. When the Quest LiteSpeed job then executed on the preferred node it was clear the previous permissions for SQL server user X had been lost on drive N and SQLSTATE 10100 was reported.
Simply added the permissions again to the backup destination drive and the issue was resolved.
Hope that helps someone.

Two things, you can use memory instead of /tmp in any kernel 2.6 by using /dev/shm (Redhat) other distros may vary. Also hget can be reimplemented using read as follows:
function hget {
while read key idx
do
if [ $key = $2 ]
then
echo $idx
return
fi
done < /dev/shm/hashmap.$1
}
In addition by assuming that all keys are unique, the return short circuits the read loop and prevents having to read through all entries. If your implementation can have duplicate keys, then simply leave out the return. This saves the expense of reading and forking both grep and awk. Using /dev/shm for both implementations yielded the following using time hget on a 3 entry hash searching for the last entry :
Grep/Awk:
hget() {
grep "^$2 " /dev/shm/hashmap.$1 | awk '{ print $2 };'
}
$ time echo $(hget FD oracle)
3
real 0m0.011s
user 0m0.002s
sys 0m0.013s
Read/echo:
$ time echo $(hget FD oracle)
3
real 0m0.004s
user 0m0.000s
sys 0m0.004s
on multiple invocations I never saw less then a 50% improvement.
This can all be attributed to fork over head, due to the use of /dev/shm
.

This version supports the -
notation and the short notation for dictionaries and lists. The following input:
global:
input:
- "main.c"
- "main.h"
flags: [ "-O3", "-fpic" ]
sample_input:
- { property1: value, property2: "value2" }
- { property1: "value3", property2: 'value 4' }
produces this output:
global_input_1="main.c"
global_input_2="main.h"
global_flags_1="-O3"
global_flags_2="-fpic"
global_sample_input_1_property1="value"
global_sample_input_1_property2="value2"
global_sample_input_2_property1="value3"
global_sample_input_2_property2="value 4"
as you can see the -
items automatically get numbered in order to obtain different variable names for each item. In bash
there are no multidimensional arrays, so this is one way to work around. Multiple levels are supported.
To work around the problem with trailing white spaces mentioned by @briceburg one should enclose the values in single or double quotes. However, there are still some limitations: Expansion of the dictionaries and lists can produce wrong results when values contain commas. Also, more complex structures like values spanning multiple lines (like ssh-keys) are not (yet) supported.
A few words about the code: The first sed
command expands the short form of dictionaries { key: value, ...}
to regular and converts them to more simple yaml style. The second sed
call does the same for the short notation of lists and converts [ entry, ... ]
to an itemized list with the -
notation. The third sed
call is the original one that handled normal dictionaries, now with the addition to handle lists with -
and indentations. The awk
part introduces an index for each indentation level and increases it when the variable name is empty (i.e. when processing a list). The current value of the counters are used instead of the empty vname. When going up one level, the counters are zeroed.
Edit: I have created a github repository for this.
For me it was that the connectionString in Startup.cs was null in:
services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
and it was null because the application was not looking into appsettings.json for the connection string.
Had to change Program.cs to:
public static void Main(string[] args)
{
BuildWebHost(args).Run();
}
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((context, builder) => builder.SetBasePath(context.HostingEnvironment.ContentRootPath)
.AddJsonFile("appsettings.json").Build())
.UseStartup<Startup>().Build();
There are few methods :
1. typeof tells you which one of the 6 javascript types is the object.
2. instanceof tells you if the object is an instance of another object.
3. List properties with for(var k in obj)
4. Object.getOwnPropertyNames( anObjectToInspect )
5. Object.getPrototypeOf( anObject )
6. anObject.hasOwnProperty(aProperty)
In a console context, sometimes the .constructor or .prototype maybe useful:
console.log(anObject.constructor );
console.log(anObject.prototype ) ;
model.predict_classes(<numpy_array>)

If you want to really get only "path" without querystring, you can use url
library to parse and get only path part of url.
var url = require('url');
//auth required or redirect
app.use('/account', function(req, res, next) {
var path = url.parse(req.url).pathname;
if ( !req.session.user ) {
res.redirect('/login?ref='+path);
} else {
next();
}
});
You could sort the array first (Ascending by default) and then apply np.flip() (https://docs.scipy.org/doc/numpy/reference/generated/numpy.flip.html)
FYI It works with datetime objects as well.
Example:
x = np.array([2,3,1,0])
x_sort_asc=np.sort(x)
print(x_sort_asc)
>>> array([0, 1, 2, 3])
x_sort_desc=np.flip(x_sort_asc)
print(x_sort_desc)
>>> array([3,2,1,0])
Simply creating a filter will do the trick. (Answered for Angular 1.6)
.filter('trustHtml', [
'$sce',
function($sce) {
return function(value) {
return $sce.trustAs('html', value);
}
}
]);
And use this as follow in the html.
<h2 ng-bind-html="someScopeValue | trustHtml"></h2>
I recommend using .htaccess
. You only need to add:
DirectoryIndex home.php
or whatever page name you want to have for it.
EDIT: basic htaccess tutorial.
1) Create .htaccess
file in the directory where you want to change the index file.
.
in front, to ensure it is a "hidden" fileEnter the line above in there. There will likely be many, many other things you will add to this (AddTypes for webfonts / media files, caching for headers, gzip declaration for compression, etc.), but that one line declares your new "home" page.
2) Set server to allow reading of .htaccess
files (may only be needed on your localhost, if your hosting servce defaults to allow it as most do)
Assuming you have access, go to your server's enabled site location. I run a Debian server for development, and the default site setup is at /etc/apache2/sites-available/default
for Debian / Ubuntu. Not sure what server you run, but just search for "sites-available" and go into the "default" document. In there you will see an entry for Directory. Modify it to look like this:
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
Then restart your apache server. Again, not sure about your server, but the command on Debian / Ubuntu is:
sudo service apache2 restart
Technically you only need to reload, but I restart just because I feel safer with a full refresh like that.
Once that is done, your site should be reading from your .htaccess file, and you should have a new default home page! A side note, if you have a sub-directory that runs a site (like an admin section or something) and you want to have a different "home page" for that directory, you can just plop another .htaccess
file in that sub-site's root and it will overwrite the declaration in the parent.
I hit this challenge today and I found these answers useful but not quite explicit enough for me.

As soulution for all libraries we can match sdk version of them so no unexpected event may happen
subprojects {
afterEvaluate {project ->
if (project.hasProperty("android")) {
android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
//It's kinda tricking android studio but anyway it works
minSdkVersion 17
}
}
}
if (project.hasProperty("dependencies")) {
dependencies {
implementation 'com.android.support:support-core-utils:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.google.android.gms:play-services-base:16.1.0'
}
}
}
}
Remove libraries that you do not use in your project (gms) and make sure that sdk version matches your app level gradle data
Simply by iterating over the list:
struct node *n = head;
while(n){
struct node *n1 = n;
n = n->next;
free(n1);
}
There is only static fields in interface that dosen't need to initialized during object creation in subclass and the method of interface has to provide actual implementation in subclass .So there is no need of constructor in interface.
Second reason-during the object creation of subclass, the parent constructor is called .But if there will be more than one interface implemented then a conflict will occur during call of interface constructor as to which interface's constructor will call first
Maybe your composer is outdated. Below are the steps to get rid of the error.
Note: For Windows professionals, Only Step2 and Step3 is needed and done.
Step1
Remove the composer:
sudo apt-get remove composer
Step2
Download the composer:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
Step3
Run composer-setup.php file
php composer-setup.php
Step4
Finally move the composer:
sudo mv composer.phar /usr/local/bin/composer
Your composer should be updated now. To check it run command:
composer
You can remove the downloaded composer by php command
php -r "unlink('composer-setup.php');"
Others have answered your question perfectly, but I just thought I would throw out another way. It's always a good idea to separate HTML markup, CSS styling, and javascript code when possible. The cleanest way to hide something, with that in mind, is using a class. It allows the definition of "hide" to be defined in the CSS where it belongs. Using this method, you could later decide you want the ul
to hide by scrolling up or fading away using CSS transition
, all without changing your HTML or code. This is longer, but I feel it's a better overall solution.
Demo: http://jsfiddle.net/ThinkingStiff/RkQCF/
HTML:
<a id="showTags" href="#" title="Show Tags">Show All Tags</a>
<ul id="subforms" class="subforums hide"><li>one</li><li>two</li><li>three</li></ul>
CSS:
#subforms {
overflow-x: visible;
overflow-y: visible;
}
.hide {
display: none;
}
Script:
document.getElementById( 'showTags' ).addEventListener( 'click', function () {
document.getElementById( 'subforms' ).toggleClass( 'hide' );
}, false );
Element.prototype.toggleClass = function ( className ) {
if( this.className.split( ' ' ).indexOf( className ) == -1 ) {
this.className = ( this.className + ' ' + className ).trim();
} else {
this.className = this.className.replace( new RegExp( '(\\s|^)' + className + '(\\s|$)' ), ' ' ).trim();
};
};
They are not the same. The first one replaces the HTML without creating another jQuery object first. The second creates an additional jQuery wrapper for the second div, then appends it to the first.
One jQuery Wrapper (per example):
$("#myDiv").html('<div id="mySecondDiv"></div>');
$("#myDiv").append('<div id="mySecondDiv"></div>');
Two jQuery Wrappers (per example):
var mySecondDiv=$('<div id="mySecondDiv"></div>');
$('#myDiv').html(mySecondDiv);
var mySecondDiv=$('<div id="mySecondDiv"></div>');
$('#myDiv').append(mySecondDiv);
You have a few different use cases going on. If you want to replace the content, .html
is a great call since its the equivalent of innerHTML = "..."
. However, if you just want to append content, the extra $()
wrapper set is unneeded.
Only use two wrappers if you need to manipulate the added div
later on. Even in that case, you still might only need to use one:
var mySecondDiv = $("<div id='mySecondDiv'></div>").appendTo("#myDiv");
// other code here
mySecondDiv.hide();
In case you care about screen size you can store screen width and Height as cookie values if they do not exists yet and then make self page redirection.
Now you have cookies on client and server side and can use it to determine mobile phones, tablets and other devices
Here a quick example how you can do it with JavaScript. Warning! [this code contain pseudo code].
if (!getcookie("screen_size")) {
var screen_width = screen.width;
var screen_height = screen.height;
setcookie("screen_size", screen_width+", " +screen_height);
go2(geturl());
}
You can add it like this
header('Location: http://linkhere.com/'.$url_endpoint);

<p class="block-with-text">The Hitch Hiker's Guide to the Galaxy has a few things to say on the subject of towels. A towel, it says, is about the most massivelyuseful thing an interstellar hitch hiker can have. Partly it has great practical value - you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you - daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough. More importantly, a towel has immense psychological value. For some reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitch hiker any of these or a dozen other items that the hitch hiker might accidentally have "lost". What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with.</p>

in exemple if you want to compile sources but have objects in an different directory :
You need to do :
gcc -c -o <obj/1.o> <srcs/1.c> <obj/2.o> <srcs/2.c> ...
but with most of macros the result will be all objects followed by all sources, like :
gcc -c -o <all OBJ path> <all SRC path>
so this will not compile anything ^^ and you will not be able to put your objects files in a different dir :(
the solution is to use these special macros
$@ $<
this will generate a .o file (obj/file.o) for each .c file in SRC (src/file.c)
$(OBJ):$(SRC)
gcc -c -o $@ $< $(HEADERS) $(FLAGS)
it means :
$@ = $(OBJ)
$< = $(SRC)
but lines by lines INSTEAD of all lines of OBJ followed by all lines of SRC
In array you also can use variables passing to req.params:
app.get(["/:foo", "/:foo/:bar"], /* function */);
In DOS you couldn't use environment variables on the command line, only in batch files, where they used the %
sign as a delimiter. If you wanted a literal %
sign in a batch file, e.g. in an echo
statement, you needed to double it.
This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your %
signs in a .cmd file.
In version that do not have information_schema
(older versions, or some ndb's) you can dump the table structure and search the column manually.
mysqldump -h$host -u$user -p$pass --compact --no-data --all-databases > some_file.sql
Now search the column name in some_file.sql
using your preferred text editor, or use some nifty awk scripts.
And a simple sed script to find the column, just replace COLUMN_NAME with your's:
sed -n '/^USE/{h};/^CREATE/{H;x;s/\nCREATE.*\n/\n/;x};/COLUMN_NAME/{x;p};' <some_file.sql
USE `DATABASE_NAME`;
CREATE TABLE `TABLE_NAME` (
`COLUMN_NAME` varchar(10) NOT NULL,
You can pipe the dump directly in sed but that's trivial.
My favourite of the below is var_dump
, which when called as:
var_dump("%d", count);
produces output like:
patch.c:150:main(): count = 0

This method creates a function that calls for the index of nth occurrences stored in an array
function nthIndexOf(search, n) {
var myArray = [];
for(var i = 0; i < myString.length; i++) { //loop thru string to check for occurrences
if(myStr.slice(i, i + search.length) === search) { //if match found...

I had the same error when i tried to send email using SmtpClient
via proxy server (Usergate).
Verifies the certificate contained the address of the server, which is not equal to the address of the proxy server, hence the error. My solution: when an error occurs while checking the certificate, receive the certificate, export it and check.
public static bool RemoteServerCertificateValidationCallback(Object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
return true;
// if got an cert auth error
if (sslPolicyErrors != SslPolicyErrors.RemoteCertificateNameMismatch) return false;
const string sertFileName = "smpthost.cer";
// check if cert file exists
if (File.Exists(sertFileName))
{
var actualCertificate = X509Certificate.CreateFromCertFile(sertFileName);
return certificate.Equals(actualCertificate);
}
// export and check if cert not exists
using (var file = File.Create(sertFileName))
{
var cert = certificate.Export(X509ContentType.Cert);
file.Write(cert, 0, cert.Length);
}
var createdCertificate = X509Certificate.CreateFromCertFile(sertFileName);
return certificate.Equals(createdCertificate);
}
