I found a better way of doing this
function genrateJSONEngine() {
var XLSX = require('xlsx');
var workbook = XLSX.readFile('test.xlsx');
var sheet_name_list = workbook.SheetNames;
sheet_name_list.forEach(function (y) {
var array = workbook.Sheets[y];
var first = array[0].join()
var headers = first.split(',');
var jsonData = [];
for (var i = 1, length = array.length; i < length; i++) {
var myRow = array[i].join();
var row = myRow.split(',');
var data = {};
for (var x = 0; x < row.length; x++) {
data[headers[x]] = row[x];
}
jsonData.push(data);
}
Alternative way of converting to csv. Use libreoffice
:
libreoffice --headless --convert-to csv *
Please be aware that this will only convert the first worksheet of your Excel file.

Work for me. ^^
You can also use the index for the sheet:
xls = pd.ExcelFile('path_to_file.xls')
sheet1 = xls.parse(0)
will give the first worksheet. for the second worksheet:
sheet2 = xls.parse(1)
I would definitely try the read.xls
function in the gdata
package, which is considerably more mature than the xlsx
package. It may require Perl ...
Simple two line code solution using pandas
import pandas as pd
read_file = pd.read_csv ('File name.csv')
read_file.to_excel ('File name.xlsx', index = None, header=True)
I had this problem and changing Extended Properties to HTML Import fixed it as per this post by Marcus Miris:
strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & importedFilePathAndName _
& ";Extended Properties=""HTML Import;HDR=No;IMEX=1"";"
Incase data size is small, R has many packages and functions which can be utilized as per your requirement.
write.xlsx, write.xlsx2, XLconnect also do the work but these are sometimes slow as compare to openxlsx.
So, if you are dealing with the large data sets and came across java errors. I would suggest to have a look of "openxlsx" which is really awesome and reduce the time to 1/12th.
I've tested all and finally i was really impressed with the performance of openxlsx capabilities.
Here are the steps for writing multiple datasets into multiple sheets.
install.packages("openxlsx")
library("openxlsx")
start.time <- Sys.time()
# Creating large data frame
x <- as.data.frame(matrix(1:4000000,200000,20))
y <- as.data.frame(matrix(1:4000000,200000,20))
z <- as.data.frame(matrix(1:4000000,200000,20))
# Creating a workbook
wb <- createWorkbook("Example.xlsx")
Sys.setenv("R_ZIPCMD" = "C:/Rtools/bin/zip.exe") ## path to zip.exe
Sys.setenv("R_ZIPCMD" = "C:/Rtools/bin/zip.exe") has to be static as it takes reference of some utility from Rtools.
Note: Incase Rtools is not installed on your system, please install it first for smooth experience. here is the link for your reference: (choose appropriate version)
https://cran.r-project.org/bin/windows/Rtools/ check the options as per link below (need to select all the check box while installation)
https://cloud.githubusercontent.com/assets/7400673/12230758/99fb2202-b8a6-11e5-82e6-836159440831.png
# Adding a worksheets : parameters for addWorksheet are 1. Workbook Name 2. Sheet Name
addWorksheet(wb, "Sheet 1")
addWorksheet(wb, "Sheet 2")
addWorksheet(wb, "Sheet 3")
# Writing data in to respetive sheets: parameters for writeData are 1. Workbook Name 2. Sheet index/ sheet name 3. dataframe name
writeData(wb, 1, x)
# incase you would like to write sheet with filter available for ease of access you can pass the parameter withFilter = TRUE in writeData function.
writeData(wb, 2, x = y, withFilter = TRUE)
## Similarly writeDataTable is another way for representing your data with table formatting:
writeDataTable(wb, 3, z)
saveWorkbook(wb, file = "Example.xlsx", overwrite = TRUE)
end.time <- Sys.time()
time.taken <- end.time - start.time
time.taken
openxlsx package is really good for reading and writing huge data from/ in excel files and has lots of options for custom formatting within excel.
The interesting fact is that we dont have to bother about java heap memory here.
you can save the xlsx file as a tab-delimited text file and do
BULK INSERT TableName
FROM 'C:\SomeDirectory\my table.txt'
WITH
(
FIELDTERMINATOR = '\t',
ROWTERMINATOR = '\n'
)
GO
Using the Gnumeric spreadsheet application which comes which a commandline utility called ssconvert is indeed super simple:
find . -name '*.xlsx' -exec ssconvert -T Gnumeric_stf:stf_csv {} \;
and you're done!
I came across the same issue. My aim is to test PHP scripts with Oracle on Windows 7 Home and without thinking installed IIS7 express and as an afterthought considered Apache as a simpler approach. I will explore IIS express's capabilities seperately.
The challenge was after installing IIS7 express the Apache installation was playing second fiddle to IIS express and bringing up the Microsoft Homepage.
I resolved the port 80 issue by :-
Technical differences are a consequence of the goal of each one (OpenJDK is meant to be the reference implementation, open to the community, while Oracle is meant to be a commercial one)
They both have "almost" the same code of the classes in the Java API; but the code for the virtual machine itself is actually different, and when it comes to libraries, OpenJDK tends to use open libraries while Oracle tends to use closed ones; for instance, the font library.
I did it by using this code:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.0/jquery.js"></script>
<script>
$(".confirm").on('click',function(){
window.location.href = "index.php";
});
</script>
Thanks.
The first 2 examples act very differently if you are REPLACING them by something. If you match on this:
str = str.replace(/^(7|8|9)/ig,'');
you would replace 7 or 8 or 9 by the empty string.
If you match on this
str = str.replace(/^[7|8|9]/ig,'');
you will replace 7
or 8
or 9
OR THE VERTICAL BAR!!!! by the empty string.
I just found this out the hard way.
Use any()
.
if any(t < 0 for t in x):
# do something
I have used this small snippet. Might be slower but works every time.
for i in 'find . -type f -name "*.jar"'; do
jar tvf $i | grep "com.foo.bar.MyClass.clss";
if [ $? -eq 0 ]; then echo $i; fi;
done
To check for an empty string you could also do something as follows
if (!defined $val || $val eq '')
{
# empty
}
You can get the actual height of called layout with this code:
public int getLayoutSize() {
// Get the layout id
final LinearLayout root = (LinearLayout) findViewById(R.id.mainroot);
final AtomicInteger layoutHeight = new AtomicInteger();
root.post(new Runnable() {
public void run() {
Rect rect = new Rect();
Window win = getWindow(); // Get the Window
win.getDecorView().getWindowVisibleDisplayFrame(rect);
// Get the height of Status Bar
int statusBarHeight = rect.top;
// Get the height occupied by the decoration contents
int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
// Calculate titleBarHeight by deducting statusBarHeight from contentViewTop
int titleBarHeight = contentViewTop - statusBarHeight;
Log.i("MY", "titleHeight = " + titleBarHeight + " statusHeight = " + statusBarHeight + " contentViewTop = " + contentViewTop);
// By now we got the height of titleBar & statusBar
// Now lets get the screen size
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenHeight = metrics.heightPixels;
int screenWidth = metrics.widthPixels;
Log.i("MY", "Actual Screen Height = " + screenHeight + " Width = " + screenWidth);
// Now calculate the height that our layout can be set
// If you know that your application doesn't have statusBar added, then don't add here also. Same applies to application bar also
layoutHeight.set(screenHeight - (titleBarHeight + statusBarHeight));
Log.i("MY", "Layout Height = " + layoutHeight);
// Lastly, set the height of the layout
FrameLayout.LayoutParams rootParams = (FrameLayout.LayoutParams)root.getLayoutParams();
rootParams.height = layoutHeight.get();
root.setLayoutParams(rootParams);
}
});
return layoutHeight.get();
}
From PEP-8: Package and Module Names:
Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability.
Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.
When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).
Didn't test this for IE, but if you make an element elem
with
min-width: 100%
then
window.document.width / elem.clientWidth
will give you your browser zoom level (including the document.body.style.zoom
factor).
(To complement Gerald's answer...) One further subtle difference is that, although the command:
svn checkout ...repos_location/my_dir .
puts the files in my_dir
into the current directory (with the .svn
folder)
in certain versions of the svn, the command:
svn export ...repos_location/my_dir .
will create a folder called my_dir
in the current directory and then place the exported files inside it.
The way I've handled it so far: in UITextFieldDelegate
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
{
// text hasn't changed yet, you have to compute the text AFTER the edit yourself
let updatedString = (textField.text as NSString?)?.stringByReplacingCharactersInRange(range, withString: string)
// do whatever you need with this updated string (your code)
// always return true so that changes propagate
return true
}
Swift4 version
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
let updatedString = (textField.text as NSString?)?.replacingCharacters(in: range, with: string)
return true
}
All else being equal, the best solution is one that clearly expresses your intent. So:
int totalSeconds = 453;
int minutes = totalSeconds / 60;
int remainingSeconds = totalSeconds % 60;
is probably the best of the three options you presented. As noted in other answers however, the div
method will calculate both values for you at once.
If I understand you need following code. (passing expression lambda by parameter) The Method
public static void Method(Expression<Func<int, bool>> predicate) {
int[] number={1,2,3,4,5,6,7,8,9,10};
var newList = from x in number
.Where(predicate.Compile()) //here compile your clausuly
select x;
newList.ToList();//return a new list
}
Calling method
Method(v => v.Equals(1));
You can do the same in their class, see this is example.
public string Name {get;set;}
public static List<Class> GetList(Expression<Func<Class, bool>> predicate)
{
List<Class> c = new List<Class>();
c.Add(new Class("name1"));
c.Add(new Class("name2"));
var f = from g in c.
Where (predicate.Compile())
select g;
f.ToList();
return f;
}
Calling method
Class.GetList(c=>c.Name=="yourname");
I hope this is useful

You can use the string.Join
method to do something like string.Join(",", o.Number, o.Id, o.whatever, ...)
.
edit: As digEmAll said, string.Join is faster than StringBuilder. They use an external implementation for the string.Join.
Profiling code (of course run in release without debug symbols):
class Program
{
static void Main(string[] args)
{
Stopwatch sw = new Stopwatch();
string r;
int iter = 10000;
string[] values = { "a", "b", "c", "d", "a little bit longer please", "one more time" };
sw.Restart();
for (int i = 0; i < iter; i++)
r = Program.StringJoin(",", values);
sw.Stop();
Console.WriteLine("string.Join ({0} times): {1}ms", iter, sw.ElapsedMilliseconds);
sw.Restart();
for (int i = 0; i < iter; i++)
r = Program.StringBuilderAppend(",", values);
sw.Stop();
Console.WriteLine("StringBuilder.Append ({0} times): {1}ms", iter, sw.ElapsedMilliseconds);
Console.ReadLine();
}
static string StringJoin(string seperator, params string[] values)
{
return string.Join(seperator, values);
}
static string StringBuilderAppend(string seperator, params string[] values)
{
StringBuilder builder = new StringBuilder();
builder.Append(values[0]);
for (int i = 1; i < values.Length; i++)
{
builder.Append(seperator);
builder.Append(values[i]);
}
return builder.ToString();
}
}
string.Join took 2ms on my machine and StringBuilder.Append 5ms. So there is noteworthy difference. Thanks to digAmAll for the hint.

For a start, you have them backwards: &
is reference and *
is dereference.
Referencing a variable means accessing the memory address of the variable:
int i = 5;
int * p;
p = &i; //&i returns the memory address of the variable i.
Dereferencing a variable means accessing the variable stored at a memory address:
int i = 5;
int * p;
p = &i;
*p = 7; //*p returns the variable stored at the memory address stored in p, which is i.
//i is now 7

Stopping (Killing) a thread mid-way is not recommended. The API is actually deprecated.
However,you can get more details including workarounds here: How do you kill a thread in Java?
I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)
That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.
According to the documentation since Symfony 2.1 simply use this shortcut :
$user = $this->getUser();
The above is still working on Symfony 3.2 and is a shortcut for this :
$user = $this->get('security.token_storage')->getToken()->getUser();
The
security.token_storage
service was introduced in Symfony 2.6. Prior to Symfony 2.6, you had to use thegetToken()
method of thesecurity.context
service.
Example : And if you want directly the username :
$username = $this->getUser()->getUsername();
The user will be an object and the class of that object will depend on your user provider.
$sql = "SELECT * FROM MY_TABLE";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!! Check summary get row on array ..
echo "<tr>";
foreach ($row as $field => $value) { // I you want you can right this line like this: foreach($row as $value) {
echo "<td>" . $value . "</td>"; // I just did not use "htmlspecialchars()" function.
}
echo "</tr>";
}
echo "</table>";

Since you've already received help on the query, I'll take a poke at your syntax question:
The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join
and on
clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.
Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:
select
count(*)
from Table1 as t1
join Table2 as t2
join Table3 as t3
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:
select
count(*)
from Table1 as t1
join Table3 as t3
join Table2 as t2
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.

First off, your quoted code is not JSON. Your code is JavaScript object literal notation. JSON is a subset of that designed for easier parsing.
Your code defines an object (data
) containing an array (items
) of objects (each with an id
, name
, and type
).
You don't need or want jQuery for this, just JavaScript.
Adding an item:
data.items.push(
{id: "7", name: "Douglas Adams", type: "comedy"}
);
That adds to the end. See below for adding in the middle.
Removing an item:
There are several ways. The splice
method is the most versatile:
data.items.splice(1, 3); // Removes three items starting with the 2nd,
// ("Witches of Eastwick", "X-Men", "Ordinary People")
splice
modifies the original array, and returns an array of the items you removed.
Adding in the middle:
splice
actually does both adding and removing. The signature of the splice
method is:
removed_items = arrayObject.splice(index, num_to_remove[, add1[, add2[, ...]]]);
index
- the index at which to start making changesnum_to_remove
- starting with that index, remove this many entriesaddN
- ...and then insert these elementsSo I can add an item in the 3rd position like this:
data.items.splice(2, 0,
{id: "7", name: "Douglas Adams", type: "comedy"}
);
What that says is: Starting at index 2, remove zero items, and then insert this following item. The result looks like this:
var data = {items: [
{id: "1", name: "Snatch", type: "crime"},
{id: "2", name: "Witches of Eastwick", type: "comedy"},
{id: "7", name: "Douglas Adams", type: "comedy"}, // <== The new item
{id: "3", name: "X-Men", type: "action"},
{id: "4", name: "Ordinary People", type: "drama"},
{id: "5", name: "Billy Elliot", type: "drama"},
{id: "6", name: "Toy Story", type: "children"}
]};
You can remove some and add some at once:
data.items.splice(1, 3,
{id: "7", name: "Douglas Adams", type: "comedy"},
{id: "8", name: "Dick Francis", type: "mystery"}
);
...which means: Starting at index 1, remove three entries, then add these two entries. Which results in:
var data = {items: [
{id: "1", name: "Snatch", type: "crime"},
{id: "7", name: "Douglas Adams", type: "comedy"},
{id: "8", name: "Dick Francis", type: "mystery"},
{id: "4", name: "Ordinary People", type: "drama"},
{id: "5", name: "Billy Elliot", type: "drama"},
{id: "6", name: "Toy Story", type: "children"}
]};
You could try using something like:
sed -n 's/$/:80/' ips.txt > new-ips.txt
Provided that your file format is just as you have described in your question.
The s///
substitution command matches (finds) the end of each line in your file (using the $
character) and then appends (replaces) the :80
to the end of each line. The ips.txt
file is your input file... and new-ips.txt
is your newly-created file (the final result of your changes.)
Also, if you have a list of IP numbers that happen to have port numbers attached already, (as noted by Vlad and as given by aragaer,) you could try using something like:
sed '/:[0-9]*$/ ! s/$/:80/' ips.txt > new-ips.txt
So, for example, if your input file looked something like this (note the :80
):
127.0.0.1
128.0.0.0:80
121.121.33.111
The final result would look something like this:
127.0.0.1:80
128.0.0.0:80
121.121.33.111:80
I've been using this little cheat for a while now. You might enjoy it. nest the table you want to center in another table:
<table height=100% width=100%>
<td align=center valign=center>
(add your table here)
</td>
</table>
the align and valign put the table exactly in the middle of the screen, no matter what else is going on.
You use std::find
from <algorithm>
, which works equally well for std::list
and std::vector
. std::vector
does not have its own search/find function.
#include <list>
#include <algorithm>
int main()
{
std::list<int> ilist;
ilist.push_back(1);
ilist.push_back(2);
ilist.push_back(3);
std::list<int>::iterator findIter = std::find(ilist.begin(), ilist.end(), 1);
}
Note that this works for built-in types like int
as well as standard library types like std::string
by default because they have operator==
provided for them. If you are using using std::find
on a container of a user-defined type, you should overload operator==
to allow std::find
to work properly: EqualityComparable
concept
Maybe you don't need it anymore but if someone needs this using node: https://www.npmjs.com/package/btoa
On apache you need to edit security.conf:
nano /etc/apache2/conf-enabled/security.conf
and set:
Header set X-Frame-Options: "sameorigin"
Then enable mod_headers:
cd /etc/apache2/mods-enabled
ln -s ../mods-available/headers.load headers.load
And restart Apache:
service apache2 restart
And voila!
My understanding is that HEAD points the current branch, while ORIG_HEAD is used to store the previous HEAD before doing "dangerous" operations.
For example git-rebase and git-am record the original tip of branch before they apply any changes.

You can actually accomplish this without JavaScript, using only JSF's rendered
attribute, by enclosing the elements to be shown/hidden in a component that can itself be re-rendered, such as a panelGroup, at least in JSF2. For example, the following JSF code shows or hides one or both of two dropdown lists depending on the value of a third. An AJAX event is used to update the display:
<h:selectOneMenu value="#{workflowProcEditBean.performedBy}">
<f:selectItem itemValue="O" itemLabel="Originator" />
<f:selectItem itemValue="R" itemLabel="Role" />
<f:selectItem itemValue="E" itemLabel="Employee" />
<f:ajax event="change" execute="@this" render="perfbyselection" />
</h:selectOneMenu>
<h:panelGroup id="perfbyselection">
<h:selectOneMenu id="performedbyroleid" value="#{workflowProcEditBean.performedByRoleID}"
rendered="#{workflowProcEditBean.performedBy eq 'R'}">
<f:selectItem itemLabel="- Choose One -" itemValue="" />
<f:selectItems value="#{workflowProcEditBean.roles}" />
</h:selectOneMenu>
<h:selectOneMenu id="performedbyempid" value="#{workflowProcEditBean.performedByEmpID}"
rendered="#{workflowProcEditBean.performedBy eq 'E'}">
<f:selectItem itemLabel="- Choose One -" itemValue="" />
<f:selectItems value="#{workflowProcEditBean.employees}" />
</h:selectOneMenu>
</h:panelGroup>

Use
document.body.innerHTML += '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';
instead of
document.body.innerHTML = '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';
Edit:-
Ideally you should use body.appendChild
method instead of changing the innerHTML
var elem = document.createElement('div');
elem.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000';
document.body.appendChild(elem);
I ran into this issue with the Oracle 11R2 client. Not sure if the Oracle installer did this or someone did it here before i arrived. It was not 64-bit vs 32-bit, all was 64-bit.
The error was that libexpat.so.1
was not a symbolic link.
It turned out that there were two identical files, libexpat.so.1.5.2
and libexpat.so.1
. Removing the offending file and making it a symlink to the 1.5.2 version caused the error to go away.
Makes sense that you'd want the well-known name to be a symlink to the current version. If you do this, it's less likely that you'll end up with a stale library.
Here's the short & sweet Swift version.
Remember to link and import the Framework:
import UIKit
import SystemConfiguration.CaptiveNetwork
Define the method:
func fetchSSIDInfo() -> CFDictionary? {
if let
ifs = CNCopySupportedInterfaces().takeUnretainedValue() as? [String],
ifName = ifs.first,
info = CNCopyCurrentNetworkInfo((ifName as CFStringRef))
{
return info.takeUnretainedValue()
}
return nil
}
Call the method when you need it:
if let
ssidInfo = fetchSSIDInfo() as? [String:AnyObject],
ssID = ssidInfo["SSID"] as? String
{
println("SSID: \(ssID)")
} else {
println("SSID not found")
}
As mentioned elsewhere, this only works on your iDevice. When not on WiFi, the method will return nil – hence the optional.

It depends a bit on your version. Before 5.0.13 this is not possible with mysqldump.
From the mysqldump man page (v 5.1.30)
--routines, -R
Dump stored routines (functions and procedures) from the dumped
databases. Use of this option requires the SELECT privilege for the
mysql.proc table. The output generated by using --routines contains
CREATE PROCEDURE and CREATE FUNCTION statements to re-create the
routines. However, these statements do not include attributes such
as the routine creation and modification timestamps. This means that
when the routines are reloaded, they will be created with the
timestamps equal to the reload time.
...
This option was added in MySQL 5.0.13. Before that, stored routines
are not dumped. Routine DEFINER values are not dumped until MySQL
5.0.20. This means that before 5.0.20, when routines are reloaded,
they will be created with the definer set to the reloading user. If
you require routines to be re-created with their original definer,
dump and load the contents of the mysql.proc table directly as
described earlier.
Interestingly, base R aggregate
's data.frame
method is not showcased here, above the formula interface is used, so for completeness:
aggregate(
x = df1[c("x1", "x2")],
by = df1[c("year", "month")],
FUN = sum, na.rm = TRUE
)
More generic use of aggregate's data.frame method:
Since we are providing a
data.frame
as x
and list
(data.frame
is also a list
) as by
, this is very useful if we need to use it in a dynamic manner, e.g. using other columns to be aggregated and to aggregate by is very simpleFor example like so:
colsToAggregate <- c("x1")
aggregateBy <- c("year", "month")
dummyaggfun <- function(v, na.rm = TRUE) {
c(sum = sum(v, na.rm = na.rm), mean = mean(v, na.rm = na.rm))
}
aggregate(df1[colsToAggregate], by = df1[aggregateBy], FUN = dummyaggfun)
Using C# 7 (.NET Framework 4.6.2) you can write an IsNumeric function as a one-liner:
public bool IsNumeric(string val) => int.TryParse(val, out int result);
Note that the function above will only work for integers (Int32). But you can implement corresponding functions for other numeric data types, like long, double, etc.
This is possible with window.localStorage
or window.sessionStorage
. The difference is that sessionStorage
lasts for as long as the browser stays open, localStorage
survives past browser restarts. The persistence applies to the entire web site not just a single page of it.
When you need to set a variable that should be reflected in the next page(s), use:
var someVarName = "value";
localStorage.setItem("someVarKey", someVarName);
And in any page (like when the page has loaded), get it like:
var someVarName = localStorage.getItem("someVarKey");
.getItem()
will return null
if no value stored, or the value stored.
Note that only string values can be stored in this storage, but this can be overcome by using JSON.stringify
and JSON.parse
. Technically, whenever you call .setItem()
, it will call .toString()
on the value and store that.
MDN's DOM storage guide (linked below), has workarounds/polyfills, that end up falling back to stuff like cookies, if localStorage
isn't available.
It wouldn't be a bad idea to use an existing, or create your own mini library, that abstracts the ability to save any data type (like object literals, arrays, etc.).

I had the same issue. Using MySQL 6.1 Workbench.
After a while (2 mins), it just crashed. Reported bug, saved files and reopened. It works now.
I guess I would suggest if that happens again, to immediately save the open scripts, close MySQL and restart it.
Setting that is not that hard as mentioned in the question. Actually it's pretty simple. Try this on storyboard.
If you don't care about this question being specifically about a tableview, and you'd just like to center one view on top of another view here's to do it:
let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0)
parentView.addConstraint(horizontalConstraint)
let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)
parentView.addConstraint(verticalConstraint)

If you're using Angularjs, you can use the angular-materialize plugin, which provides some handy directives. Then you don't need to initialize in the js, just add material-select
to your select:

<select class="" ng-model="select.value1" material-select>
<option ng-repeat="value in select.choices">{{value}}</option>
</select>
</div>
Whoa whoa whoa. Is there a specific reason you're using floating-point for currency, or would things be better off with an arbitrary-precision, fixed-point number format? I have no idea what the specific problem that you're trying to solve is, but you should think about whether or not half a cent is really something you want to work with, or if it's just an artifact of using an imprecise number format.

The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.
You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \r
rather than the linux standard \n
or better still the suspenders and belt approach of windows with \r\n

pandas.read_csv(filename, sep='\t', lineterminator='\r')
You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.

doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set
df = pandas.read_csv(doc, sep='\t')

My Answer: All of the following should be overridden (i.e. describe them all within columndefinition
, if appropriate):
length
precision
scale
nullable
unique
i.e. the column DDL will consist of: name
+ columndefinition
and nothing else.
Rationale follows.
Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.
Other annotation purely logical - properties used in-memory in java to control JPA processing.
That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true)
and once via @Column(...,nullable=true)
. Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.
In your example, length and nullable properties are overridden and redundant.
So, when specifying columnDefinition, what other properties of @Column are made redundant?
In JPA Spec & javadoc:
columnDefinition
definition:
The SQL fragment that is used when generating the DDL for the column.
columnDefinition
default:
Generated SQL to create a column of the inferred type.
The following examples are provided:
@Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
@Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
And, err..., that's it really. :-$ ?!
Does columnDefinition override other properties provided in the same annotation?
The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.
The following can be safely implied from examples provided in the JPA spec
name
& table
can be used in conjunction with columnDefinition
, neither are overriddennullable
is overridden/made redundant by columnDefinition
The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):
length
, precision
, scale
are overridden/made redundant by the columnDefinition
- they are integral to the typeinsertable
and updateable
are provided separately and never included in columnDefinition
, because they control SQL generation in-memory, before it is emmitted to the database.That leaves just the "unique
" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.
Test My Answer For columns "A" & "B", respectively:
@Column(name="...", table="...", insertable=true, updateable=false,
columndefinition="NUMBER(5,2) NOT NULL UNIQUE"
@Column(name="...", table="...", insertable=false, updateable=true,
columndefinition="NVARCHAR2(100) NULL"
Short version:
Suppose you have two tensors, where y_hat
contains computed scores for each class (for example, from y = W*x +b) and y_true
contains one-hot encoded true labels.
y_hat = ... # Predicted label, e.g. y = tf.matmul(X, W) + b
y_true = ... # True label, one-hot encoded
If you interpret the scores in y_hat
as unnormalized log probabilities, then they are logits.
Additionally, the total cross-entropy loss computed in this manner:
y_hat_softmax = tf.nn.softmax(y_hat)
total_loss = tf.reduce_mean(-tf.reduce_sum(y_true * tf.log(y_hat_softmax), [1]))
is essentially equivalent to the total cross-entropy loss computed with the function softmax_cross_entropy_with_logits()
:
total_loss = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true))
Long version:
In the output layer of your neural network, you will probably compute an array that contains the class scores for each of your training instances, such as from a computation y_hat = W*x + b
. To serve as an example, below I've created a y_hat
as a 2 x 3 array, where the rows correspond to the training instances and the columns correspond to classes. So here there are 2 training instances and 3 classes.
import tensorflow as tf
import numpy as np
sess = tf.Session()
# Create example y_hat.
y_hat = tf.convert_to_tensor(np.array([[0.5, 1.5, 0.1],[2.2, 1.3, 1.7]]))
sess.run(y_hat)
# array([[ 0.5, 1.5, 0.1],
# [ 2.2, 1.3, 1.7]])
Note that the values are not normalized (i.e. the rows don't add up to 1). In order to normalize them, we can apply the softmax function, which interprets the input as unnormalized log probabilities (aka logits) and outputs normalized linear probabilities.
y_hat_softmax = tf.nn.softmax(y_hat)
sess.run(y_hat_softmax)
# array([[ 0.227863 , 0.61939586, 0.15274114],
# [ 0.49674623, 0.20196195, 0.30129182]])
It's important to fully understand what the softmax output is saying. Below I've shown a table that more clearly represents the output above. It can be seen that, for example, the probability of training instance 1 being "Class 2" is 0.619. The class probabilities for each training instance are normalized, so the sum of each row is 1.0.
Pr(Class 1) Pr(Class 2) Pr(Class 3)
,--------------------------------------
Training instance 1 | 0.227863 | 0.61939586 | 0.15274114
Training instance 2 | 0.49674623 | 0.20196195 | 0.30129182
So now we have class probabilities for each training instance, where we can take the argmax() of each row to generate a final classification. From above, we may generate that training instance 1 belongs to "Class 2" and training instance 2 belongs to "Class 1".
Are these classifications correct? We need to measure against the true labels from the training set. You will need a one-hot encoded y_true
array, where again the rows are training instances and columns are classes. Below I've created an example y_true
one-hot array where the true label for training instance 1 is "Class 2" and the true label for training instance 2 is "Class 3".
y_true = tf.convert_to_tensor(np.array([[0.0, 1.0, 0.0],[0.0, 0.0, 1.0]]))
sess.run(y_true)
# array([[ 0., 1., 0.],
# [ 0., 0., 1.]])
Is the probability distribution in y_hat_softmax
close to the probability distribution in y_true
? We can use cross-entropy loss to measure the error.
We can compute the cross-entropy loss on a row-wise basis and see the results. Below we can see that training instance 1 has a loss of 0.479, while training instance 2 has a higher loss of 1.200. This result makes sense because in our example above, y_hat_softmax
showed that training instance 1's highest probability was for "Class 2", which matches training instance 1 in y_true
; however, the prediction for training instance 2 showed a highest probability for "Class 1", which does not match the true class "Class 3".
loss_per_instance_1 = -tf.reduce_sum(y_true * tf.log(y_hat_softmax), reduction_indices=[1])
sess.run(loss_per_instance_1)
# array([ 0.4790107 , 1.19967598])
What we really want is the total loss over all the training instances. So we can compute:
total_loss_1 = tf.reduce_mean(-tf.reduce_sum(y_true * tf.log(y_hat_softmax), reduction_indices=[1]))
sess.run(total_loss_1)
# 0.83934333897877944
Using softmax_cross_entropy_with_logits()
We can instead compute the total cross entropy loss using the tf.nn.softmax_cross_entropy_with_logits()
function, as shown below.
loss_per_instance_2 = tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true)
sess.run(loss_per_instance_2)
# array([ 0.4790107 , 1.19967598])
total_loss_2 = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true))
sess.run(total_loss_2)
# 0.83934333897877922
Note that total_loss_1
and total_loss_2
produce essentially equivalent results with some small differences in the very final digits. However, you might as well use the second approach: it takes one less line of code and accumulates less numerical error because the softmax is done for you inside of softmax_cross_entropy_with_logits()
.

params.flags = WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;
//TODO Store original brightness value
params.screenBrightness = 0.1f;
this.getWindow().setAttributes(params);
/** Turn on: */
params.flags = WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;
//TODO restoring from original value
params.screenBrightness = 0.9f;

I was using Spring Tool Suite 4. Not able to figure out the issue. The directory structure was according to the package name.
But cleaning the project helped me.
Maybe a little late to the party but why don't you use sessions to store your data?
bookingfacilities.php
session_start();
$_SESSION['form_date'] = $date;
successfulbooking.php
session_start();
$date = $_SESSION['form_date'];
Nobody will see this.
I also had the same issue, but the problem was with the Target framework of the assembly.
The referenced assembly was in .NET Framework 4.6 where the project has set to .NET framework 4.5.
Hope this will help to someone who messed up with frameworks.
Use JSON to transfer data types (arrays and objects) between client and server.
In PHP:
In JavaScript:
PHP:
echo json_encode($id_numbers);
JavaScript:
id_numbers = JSON.parse(msg);
As Wolfgang mentioned, you can give a fourth parameter to jQuery to automatically decode JSON for you.
id_numbers = new Array();
$.ajax({
url:"Example.php",
type:"POST",
success:function(msg){
id_numbers = msg;
},
dataType:"json"
});
we are in 2017 now you can also use ES2016
var a = 'abc123.8<blah>';
console.log([...a].filter( e => isFinite(e)).join(''));
or
console.log([...'abc123.8<blah>'].filter( e => isFinite(e)).join(''));
The result is

This is probably what you want:

using(WindowsIdentity.GetCurrent().Impersonate())

}
But I really need more details to help you out. You could do impersonation with a config file (if you're trying to do this on a website), or through method decorators (attributes) if it's a WCF service, or through... you get the idea.
Also, if we're talking about impersonating a client that called a particular service (or web app), you need to configure the client correctly so that it passes the appropriate tokens.
Finally, if what you really want do is Delegation, you also need to setup AD correctly so that users and machines are trusted for delegation.
Edit:
Take a look here to see how to impersonate a different user, and for further documentation.

You can either have the newly inserted ID being output to the SSMS console like this:
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar()
(instead of .ExecuteNonQuery()
) to read the resulting ID
back.
Or if you need to capture the newly inserted ID
inside T-SQL (e.g. for later further processing), you need to create a table variable:
DECLARE @OutputTbl TABLE (ID INT)
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
This way, you can put multiple values into @OutputTbl
and do further processing on those. You could also use a "regular" temporary table (#temp
) or even a "real" persistent table as your "output target" here.
Follow this steps:
-Build
-Generate Signed Apk
-Create new
Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)
Just put your file.exe in the \bin\Debug folder and use:

ALTER TABLE MasterTable
ADD CONSTRAINT fk_xyz
FOREIGN KEY (xyz)
REFERENCES ChildTable (xyz) ON DELETE CASCADE
Supported by SQL Server 2005 and later versions
SELECT CONVERT(VARCHAR(10), GETDATE(), 101)
+ ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)
* See Microsoft's documentation to understand what the 101
and 108
style codes above mean.
Supported by SQL Server 2012 and later versions
SELECT FORMAT(GETDATE() , 'MM/dd/yyyy HH:mm:ss')

Both of the above methods will return:

Here is another way to do it:
isempty = (dict1 and True) or False
if dict1 is empty then dict1 and True will give {} and this when resolved with False gives False.
if dict1 is non-empty then dict1 and True gives True and this resolved with False gives True

Open keyChain Access to see whether there are two same Certifications ,If there's two or more,Just Delete to one and it will work :)
I closed all the other projects and run my required project in isolation in Pycharm. I created a separate virtualenv from pycharm and added all the required modules in it by using pip. I added this virtual environment in project's interpreter. This solved my problem.
If you use the command
time /T
that will print the time. (without the /T, it will try to set the time)
date /T
is similar for the date.
If cmd's Command Extensions are enabled (they are enabled by default, but in this question they appear to be disabled), then the environment variables %DATE%
and %TIME%
will expand to the current date and time each time they are expanded. The format used is the same as the DATE
and TIME
commands.
To see the other dynamic environment variables that exist when Command Extensions are enabled, run set /?
.
The Timer function also applies to Access 2007, Access 2010, Access 2013, Access 2016, Access 2007 Developer, Access 2010 Developer, Access 2013 Developer. Insert this code to to pause time for certain amount of seconds
T0 = Timer
Do
Delay = Timer - T0
Loop Until Delay = 1 'Change this value to pause time in second

This provides you to retrieve information from your URI strings
$this->uri->segment(n); // n=1 for controller, n=2 for method, etc
Consider this example:
http://example.com/index.php/controller/action/1stsegment/2ndsegment
it will return
$this->uri->segment(1); // controller
$this->uri->segment(2); // action
$this->uri->segment(3); // 1stsegment
$this->uri->segment(4); // 2ndsegment
if you datatype is datetime of the table.col , then database store data contain two partial : 1 (date) 2 (time)
Just in display data use convert or cast.
Example:
create table #test(part varchar(10),lastTime datetime)
go
insert into #test (part ,lastTime )
values('A','2012-11-05 ')
insert into #test (part ,lastTime )
values('B','2012-11-05 10:30')
go
select * from #test
A 2012-11-05 00:00:00.000
B 2012-11-05 10:30:00.000
select part,CONVERT (varchar,lastTime,111) from #test
A 2012/11/05
B 2012/11/05
select part,CONVERT (varchar(10),lastTime,20) from #test
A 2012-11-05
B 2012-11-05
since function is first-class citizen, you can write small wrapper (from Alex answers)
def repeat(f, N):
for _ in itertools.repeat(None, N): f()
then you can pass function as argument.
If you came here from google because tab isnt indenting, this can also be because "Tab Moves Focus" is on. It is at the bottom right, and if you have a large enough monitor you may miss it despite it being highlighted.
Click the Green area or Ctrl + M to make it stop. I'm not sure it can be disabled entirely, then again I dont know why a code editor would want to mess with something like indenting.
As Cheesle said, you can unpack and your library Jars and re-jar them all with the following modification.
<jar destfile="${jar.file}"
basedir="${build.dir}"
manifest="${manifest.file}">
<fileset dir="${classes.dir}" includes="**/*.class" />
<zipgroupfileset dir="${lib.dir}" includes="**/*.jar" />
</jar>
Jar files are really just zip files with a manifest file embedded. You can extract and repackage the dependency Jars into your application's Jar file.
http://ant.apache.org/manual/Tasks/zip.html "The Zip task also supports the merging of multiple zip files into the zip file. This is possible through either the src attribute of any nested filesets or by using the special nested fileset zipgroupfileset."
Do pay attention to the licenses involved with your dependency libaries. Linking externally to a library and including the library in your application are very different things legally.
EDIT 1: Darn my slow typing. Grodriguez beat me to it. :)
EDIT 2: If you decide you can't include your dependencies into your application then you have to specify them in your Jar's classpath either at the command line at startup or via the Manifest file. There's a nice command in ANT to handle the special formatting of the classpath in a Manifest file for you.
<manifestclasspath property="manifest.classpath" jarfile="${jar.file}">
<classpath location="${lib.dir}" />
</manifestclasspath>
<manifest file="${manifest.file}" >
<attribute name="built-by" value="${user.name}" />
<attribute name="Main-Class" value="${main.class}" />
<attribute name="Class-Path" value="${manifest.classpath}" />
</manifest>

To make a FULL jQuery plugin as .outerHTML
, add the following script to any js file and include after jQuery in your header:
update New version has better control as well as a more jQuery Selector friendly service! :)
;(function($) {
$.extend({
outerHTML: function() {
var $ele = arguments[0],
args = Array.prototype.slice.call(arguments, 1)
if ($ele && !($ele instanceof jQuery) && (typeof $ele == 'string' || $ele instanceof HTMLCollection || $ele instanceof Array)) $ele = $($ele);
if ($ele.length) {
if ($ele.length == 1) return $ele[0].outerHTML;
else return $.map($("div"), function(ele,i) { return ele.outerHTML; });
}
throw new Error("Invalid Selector");
}
})
$.fn.extend({
outerHTML: function() {
var args = [this];
if (arguments.length) for (x in arguments) args.push(arguments[x]);
return $.outerHTML.apply($, args);
}
});
})(jQuery);
This will allow you to not only get the outerHTML of one element, but even get an Array return of multiple elements at once! and can be used in both jQuery standard styles as such:
$.outerHTML($("#eleID")); // will return outerHTML of that element and is
// same as
$("#eleID").outerHTML();
// or
$.outerHTML("#eleID");
// or
$.outerHTML(document.getElementById("eleID"));
For multiple elements
$("#firstEle, .someElesByClassname, tag").outerHTML();
console.log('$.outerHTML($("#eleID"))'+"\t", $.outerHTML($("#eleID"))); _x000D_
console.log('$("#eleID").outerHTML()'+"\t\t", $("#eleID").outerHTML());_x000D_

From ios 10.0 we need set { self.orientations = newValue }
for setting up the orientation, Make sure landscape property is enabled in your project.
private var orientations = UIInterfaceOrientationMask.landscapeLeft
override var supportedInterfaceOrientations : UIInterfaceOrientationMask {
get { return self.orientations }
set { self.orientations = newValue }
}
If you need run code after 100% loaded with image and files, test this in mounted()

if (document.readyState == "complete") {
console.log('Page completed with image and files!')
// fetch to next page or some code
}
}

Convert binary file to base64 & vice versa. Prove in python 3.5.2
import base64
read_file = open('/tmp/newgalax.png', 'rb')
data = read_file.read()
b64 = base64.b64encode(data)
print (b64)
# Save file
decode_b64 = base64.b64decode(b64)
out_file = open('/tmp/out_newgalax.png', 'wb')
out_file.write(decode_b64)
# Test in python 3.5.2
You can indeed match all those characters, but it's safer to escape the -
so that it is clear that it be taken literally.
If you are using a POSIX variant you can opt to use:
([[:alnum:]\-_]+)
But a since you are including the underscore I would simply use:
([\w\-]+)
(works in all variants)
echo : echo is a language construct where there is not required to use parentheses with it and it can take any number of parameters and return void.
void echo (param1,param2,param3.....);
Example: echo "test1","test2,test3";
print : it is a language construct where there is not required to use parentheses it just take one parameter and return
1 always.
int print(param1);
print "test1";
print "test1","test2"; // It will give syntax error
prinf : It is a function which takes atleast one string and format style and returns length of output string.
int printf($string,$s);
$s= "Shailesh";
$i= printf("Hello %s how are you?",$s);
echo $i;
Output : Hello Shailesh how are you?
27
echo returns void so its execution is faster than print and printf
binary tree :
No need to consider values, we need to look at the structrue.

We need to consider even the node values. We call it as Catalan Number

To have an animated hamburger icon you should use DrawerLayout
with ActionBarDrawerToggle
and enable the icon for the ActionBar
and for the ActionBarDrawerToggle
.
Example:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle;
setSupportActionBar(toolbar);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null)
{
actionBar.setDisplayHomeAsUpEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.hello_world, R.string.hello_world)
{
public void onDrawerClosed(View view)
{
supportInvalidateOptionsMenu();
//drawerOpened = false;
}
public void onDrawerOpened(View drawerView)
{
supportInvalidateOptionsMenu();
//drawerOpened = true;
}
};
mDrawerToggle.setDrawerIndicatorEnabled(true);
drawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
}
Also, you need to add these methods to your Activity:
@Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
While waiting for the adoption of CSS3 targeting by the major browsers, one could run the following sed
command once the (X)HTML has been created:
sed -i 's|href="http|target="_blank" href="http|g' index.html
It will add target="_blank"
to all external hyperlinks. Variations are also possible.
EDIT
I use this at the end of the makefile
which generates every web page on my site.
DAYS360
does not calculate what you want, i.e. the number of days passed between the two dates. Use simple subtraction (-
) or MINUS()
. I made an updated copy of @DrCord’s sample spreadsheet to illustrate this.
Are you SURE you want DAYS360? That is a specialized function used in the financial sector to simplify calculations for bonds. It assumes a 360 day year, with 12 months of 30 days each. If you really want actual days, you'll lose 6 days each year. [source]
Modern answer: use java.time, the modern Java date and time API, for your date and time work. Back in 2011 it was right to use the Timestamp
class, but since JDBC 4.2 it is no longer advised.
For your work we need a time zone and a couple of formatters. We may as well declare them static:
static ZoneId zone = ZoneId.of("America/Marigot");
static DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
static DateTimeFormatter timeFormatter = DateTimeFormatter.ofPattern("HH:mm xx");
Now the code could be for example:
while(resultSet.next()) {
ZonedDateTime dtStart = resultSet.getObject("dtStart", OffsetDateTime.class)
.atZoneSameInstant(zone);
// I would like to then have the date and time
// converted into the formats mentioned...
String dateFormatted = dtStart.format(dateFormatter);
String timeFormatted = dtStart.format(timeFormatter);
System.out.format("Date: %s; time: %s%n", dateFormatted, timeFormatted);
}
Example output (using the time your question was asked):
Date: 09/20/2011; time: 18:13 -0400
In your database timestamp with time zone
is recommended for timestamps. If this is what you’ve got, retrieve an OffsetDateTime
as I am doing in the code. I am also converting the retrieved value to the user’s time zone before formatting date and time separately. As time zone I supplied America/Marigot as an example, please supply your own. You may also leave out the time zone conversion if you don’t want any, of course.
If the datatype in SQL is a mere timestamp
without time zone, retrieve a LocalDateTime
instead. For example:
ZonedDateTime dtStart = resultSet.getObject("dtStart", LocalDateTime.class)
.atZone(zone);
No matter the details I trust you to do similarly for dtEnd
.
I wasn’t sure what you meant by the xx
in HH:MM xx
. I just left it in the format pattern string, which yields the UTC offset in hours and minutes without colon.
Link: Oracle tutorial: Date Time explaining how to use java.time.
Instead of overwriting the html every time, just toggle the class.
$('#click_advance').click(function() {
$('#display_advance').toggle('1000');
$("i", this).toggleClass("icon-circle-arrow-up icon-circle-arrow-down");
});

I just came across this problem and have written a solution for those of you who are using Angular. You can write a custom directive composed of a container, a button, and an input element with type file. With CSS you then place the input over the custom button but with opacity 0. You set the containers height and width to exactly the offset width and height of the button and the input's height and width to 100% of the container.
the directive
angular.module('myCoolApp')
.directive('fileButton', function () {
return {
templateUrl: 'components/directives/fileButton/fileButton.html',
restrict: 'E',
link: function (scope, element, attributes) {
var container = angular.element('.file-upload-container');
var button = angular.element('.file-upload-button');
container.css({
position: 'relative',
overflow: 'hidden',
width: button.offsetWidth,
height: button.offsetHeight
})
}
};
});
a jade template if you are using jade
div(class="file-upload-container")
button(class="file-upload-button") +
input#file-upload(class="file-upload-input", type='file', onchange="doSomethingWhenFileIsSelected()")
the same template in html if you are using html
<div class="file-upload-container">
<button class="file-upload-button"></button>
<input class="file-upload-input" id="file-upload" type="file" onchange="doSomethingWhenFileIsSelected()" />
</div>
the css
.file-upload-button {
margin-top: 40px;
padding: 30px;
border: 1px solid black;
height: 100px;
width: 100px;
background: transparent;
font-size: 66px;
padding-top: 0px;
border-radius: 5px;
border: 2px solid rgb(255, 228, 0);
color: rgb(255, 228, 0);
}
.file-upload-input {
position: absolute;
top: 0;
left: 0;
z-index: 2;
width: 100%;
height: 100%;
opacity: 0;
cursor: pointer;
}
This post was helpful, but just wanted to share a slight alternative that may help others:
Setting max-height
instead of height
also does the trick. In my case, I'm disabling scrolling based on a class toggle. Setting .someContainer {height: 100%; overflow: hidden;}
when the container's height is smaller than that of the viewport would stretch the container, which wouldn't be what you'd want. Setting max-height
accounts for this, but if the container's height is greater than the viewport's when the content changes, still disables scrolling.
It would take me a lot of convincing to switch from perforce. In the two companies I used it it was more than adequate. Those were both companies with disparate offices, but the offices were set up with plenty of infrastructure so there was no need to have the disjoint/disconnected features.
How many developers are you talking about changing over?
The real question is - what is it about perforce that is not meeting your organization's needs that git can provide? And similarly, what weaknesses does git have compared to perforce? If you can't answer that yourself then asking here won't help. You need to find a business case for your company. (e.g. Perhaps it is with lower overall cost of ownership (that includes loss of productivity for the interim learning stage, higher admin costs (at least initially), etc.)
I think you are in for a tough sell - perforce is a pretty good one to try to replace. It is a no brainer if you are trying to boot out pvcs or ssafe.
I face same problem on chrome with ckeditor 4.7.1. Just disable pasteFilter on ckeditor instanceReady.This property disable all filter options of Advance Content Filter(ACF).
CKEDITOR.on('instanceReady', function (ev) {
ev.editor.pasteFilter.disabled = true;
});
The problem with the PHP $_SERVER['HTTP_REFFERER'] is that it gives the fully qualified page url of the page that brought you to the parent page. That's not the same as the parent page, itself. Worse, sometimes there is no http_referer, because the person typed in the url of the parent page. So, if I get to your parent page from yahoo.com, then yahoo.com becomes the http_referer, not your page.
You could just use a margin-left with a percentage.
HTML
<div class="goleft">Left Div</div>
<div class="goright">Right Div</div>
CSS
.goright{
margin-left:20%;
}
.goleft{
margin-right:20%;
}
(goleft would be the same as default, but can reverse if needed)
text-align doesn't always work as intended for layout options, it's mainly just for text. (But is often used for form elements too).
The end result of doing this will have a similar effect to a div with float:right; and width:80% set. Except, it won't clump together like a float will. (Saving the default display properties for the elements that come after).
you can do this by
date("F j, Y", time() - 60 * 60 * 24);
or by
date("F j, Y", strtotime("yesterday"));

You can use the function last_insert_rowid()
:
The
last_insert_rowid()
function returns theROWID
of the last row insert from the database connection which invoked the function. Thelast_insert_rowid()
SQL function is a wrapper around thesqlite3_last_insert_rowid()
C/C++ interface function.

You can try a Java Library. FileUtils, It has many functions that write to Files.
ngStyle directive allows you to set CSS style on an HTML element dynamically.
Expression which evals to an object whose keys are CSS style names and values are corresponding values for those CSS keys. Since some CSS style names are not valid keys for an object, they must be quoted.
ng-style="{color: myColor}"
Your code will be:
<div ng-style="{'width':'20px', 'height':'20px', 'margin-top':'10px', 'border':'solid 1px black', 'background-color':'#ff0000'}"></div>
If you want to use scope variables:
<div ng-style="{'background-color': data.backgroundCol}"></div>

An alternative solution is to execute an external command, obviously, this solution limits the portability of the application.
For example, for an application that runs on Windows, a PowerShell command can be executed through jPowershell, as shown in the following code:
public String getMyPublicIp() {
// PowerShell command
String command = "(Invoke-WebRequest ifconfig.me/ip).Content.Trim()";
String powerShellOut = PowerShell.executeSingleCommand(command).getCommandOutput();
// Connection failed
if (powerShellOut.contains("InvalidOperation")) {
powerShellOut = null;
}
return powerShellOut;
}
I wasn't happy with any of these approaches, so I came up with a Flexlist
class that allows for flexible indexing, either by integer, slice or index-list:
class Flexlist(list):
def __getitem__(self, keys):
if isinstance(keys, (int, slice)): return list.__getitem__(self, keys)
return [self[k] for k in keys]
Which, for your example, you would use as:
L = Flexlist(['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'])
Idx = [0, 3, 7]
T = L[ Idx ]
print(T) # ['a', 'd', 'h']
In JSFiddle, when you set the wrapping to "onLoad" or "onDomready", the functions you define are only defined inside that block, and cannot be accessed by outside event handlers.
Easiest fix is to change:
function something(...)
To:
window.something = function(...)
I thought a fully-functioning reCaptcha v3 example demo in PHP, using a Bootstrap 4 form, might be useful to some.
Reference the shown dependencies, swap in your email address and keys (create your own keys here), and the form is ready to test and use. I made code comments to better clarify the logic and also included commented-out console log and print_r lines to quickly enable viewing the validation token and data generated from Google.
The included jQuery function is optional, though it does create a much better user prompt experience in this demo.

):Add secret key (2 places) and email address where noted.

If someone else needs a guaranteed way of STRICTLY sequential way of resolving Promises when performing CRUD operations you also can use the following code as a basis.
As long as you add 'return' before calling each function, describing a Promise, and use this example as a basis the next .then() function call will CONSISTENTLY start after the completion of the previous one:
getRidOfOlderShoutsPromise = () => {
return readShoutsPromise('BEFORE')
.then(() => {
return deleteOlderShoutsPromise();
})
.then(() => {
return readShoutsPromise('AFTER')
})
.catch(err => console.log(err.message));
}
deleteOlderShoutsPromise = () => {
return new Promise ( (resolve, reject) => {
console.log("in deleteOlderShouts");
let d = new Date();
let TwoMinuteAgo = d - 1000 * 90 ;
All_Shouts.deleteMany({ dateTime: {$lt: TwoMinuteAgo}}, function(err) {
if (err) reject();
console.log("DELETED OLDs at "+d);
resolve();
});
});
}
readShoutsPromise = (tex) => {
return new Promise( (resolve, reject) => {
console.log("in readShoutsPromise -"+tex);
All_Shouts
.find({})
.sort([['dateTime', 'ascending']])
.exec(function (err, data){
if (err) reject();
let d = new Date();
console.log("shouts "+tex+" delete PROMISE = "+data.length +"; date ="+d);
resolve(data);
});
});
}
4gb RAM doesn't mean you can use it all for java process. Lots of RAM is needed for system processes. Dont go above 2GB or it will be trouble some.
Before starting jvm just check how much RAM is available and then set memory accordingly.
In summary :
<input type="submit">
<button type="submit"> Submit </button>
Both by default will visually draw a button that performs the same action (submit the form).
However, it is recommended to use <button type="submit">
because it has better semantics, better ARIA support and it is easier to style.
The below made sense for 2013. However, now, I would use the :not()
selector as described below.
CSS can be overwritten.

Notice I have this in a class lib, so thus the "self::validate_phone_number" call from the first function/method.
Notice line # 32 of the "validate_phone_number" function where I added the:
if ( !$valid['format'] ) {
return false;
} else {
to get me the false return needed if not valid phone number.
Still need to test this against more data, but working on current data, with current format and I'm using style '8' for this particular data batch.
Also I commented out the "extension" logic as I was constantly getting errors from it, seeing I do not have any of that info in my data.
getUserVisibleHint()
comes as true only when the fragment is on the view and visible
To do this, you can loop through one and append to the other:
<?php
$test1 = array(
'11' => '11',
'22' => '22',
'33' => '33',
'44' => '44'
);
$test2 = array(
'44' => '44',
'55' => '55',
'66' => '66',
'77' => '77'
);
function combineWithKeys($array1, $array2)
{
foreach($array1 as $key=>$value) $array2[$key] = $value;
asort($array2);
return $array2;
}
print_r(combineWithKeys($test1, $test2));
?>
UPDATE: KingCrunch came up with the best solution: print_r($array1+$array2);
The file in question is not using the CP1252
encoding. It's using another encoding. Which one you have to figure out yourself. Common ones are Latin-1
and UTF-8
. Since 0x90 doesn't actually mean anything in Latin-1
, UTF-8
(where 0x90 is a continuation byte) is more likely.
You specify the encoding when you open the file:
file = open(filename, encoding="utf8")
document.getElementById('username').value = 'foo';
document.getElementById('login_form').submit();
I solved this problem by enabling WCF Services
Programs and Features > NET Framework 4.5 Services > WCF Services> HTTP Activation node
But you have to admit it guys this ENTIRE IIS setup configure/guess/trial and see/try this/try that spends 4 or 5 of our days trying to find a solution around approach IS A COMPLETE AND UTTER JOKE.
SURELY, 'IIS' IS THE BIGGEST CONFIDENCE TRICK EVER PLAYED ON MANKIND TO DATE
Not a direct answer but seemed relevant enough to be tacked on as it saves a bit of verbose tedium on occasion. Cut straight from the docs...
Given a class defining one or more rich comparison ordering methods, this class decorator supplies the rest. This simplifies the effort involved in specifying all of the possible rich comparison operations:
The class must define one of __lt__()
, __le__()
, __gt__()
, or __ge__()
. In addition, the class should supply an __eq__()
method.
New in version 2.7
@total_ordering
class Student:
def __eq__(self, other):
return ((self.lastname.lower(), self.firstname.lower()) ==
(other.lastname.lower(), other.firstname.lower()))
def __lt__(self, other):
return ((self.lastname.lower(), self.firstname.lower()) <
(other.lastname.lower(), other.firstname.lower()))
You can filter the results based on formatted date using mysql (See here for Mysql/Mariadb help) and use something like this in laravel-5.4:
Model::selectRaw("COUNT(*) views, DATE_FORMAT(created_at, '%Y %m %e') date")
->groupBy('date')
->get();
My minimalistic solution should work for random numbers in range [min, max)
. Use srand(time(NULL))
before invoking the function.
int range_rand(int min_num, int max_num) {
if (min_num >= max_num) {
fprintf(stderr, "min_num is greater or equal than max_num!\n");
}
return min_num + (rand() % (max_num - min_num));
}
The error is because there is some non-ascii character in the dictionary and it can't be encoded/decoded. One simple way to avoid this error is to encode such strings with encode()
function as follows (if a
is the string with non-ascii character):
a.encode('utf-8').strip()
First, you show that it lies in NP at all.
Then you find another problem that you already know is NP complete and show how you polynomially reduce NP Hard problem to your problem.
Let's try this way:
select
a.ip,
a.os,
a.hostname,
a.port,
a.protocol,
b.state
from a
left join b
on a.ip = b.ip
and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/
So, in where
clause you can filter result set by column from right table only on this way:
...
where b.somecolumn <> (=) null
lapply is pretty much designed for this
unfactorize<-c("colA","colB")
df[,unfactorize]<-lapply(unfactorize, function(x) as.numeric(as.character(df[,x])))
Your best bet is to use NET SEND
as documented on Rob van der Woude's site.
Otherwise, you'll need to use an external scripting program. Batch files are really intended to send messages via ECHO
.
yum uses RPM, so the following command will list the contents of the installed package:
$ rpm -ql package-name
nohup some_command > /dev/null 2>&1&
That's all you need to do!
I wanted to change the indentation of my existing HTML file from 4 spaces to 2 spaces.
I clicked the 'Spaces: 4' button in the status bar and changed them to two in the next dialog box.
I use 'vim' extension. I don't how to re-indent without vim
To re-indent my current file, I used this:
gg

G
You can use:
Resources.getSystem().getString(android.R.string.somecommonstuff)
... everywhere in your application, even in static constants declarations. Unfortunately, it supports the system resources only.
For local resources use this solution. It is not trivial, but it works.
To redirect your logs output to a file, you need to use the FileAppender and need to define other file details in your log4j.properties/xml file. Here is a sample properties file for the same:
# Root logger option
log4j.rootLogger=INFO, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\loging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Just add position:relative
to the parent element .sidebar-resources-categories
http://jsfiddle.net/matthewabrman/5msuY/
explanation: the ::after elements position is based off of it's parent, in your example you probably had a parent element of the .sidebar-res... which had a set height, therefore it rendered just below it. Adding position relative to the .sidebar-res... makes the after elements move to 100% of it's parent which now becomes the .sidebar-res... because it's position is set to relative. I'm not sure how to explain it but it's expected behaviour.

Posting hoping that it may help others...
Steps:
FIRST, configure the php-fpm settings:
-> systemctl stop php-fpm.service
-> cd /etc/php-fpm.d
-> ls -hal
(should see a www.conf file)
-> cp www.conf www.conf.backup
(back file up just in case)
-> vi www.conf
-> :/listen =
(to get to the line we need to change)
-> i
(to enter VI's text insertion mode)
-> change from listen = 127.0.0.1:9000
TO listen = /var/run/php-fpm/php-fpm.sock
-> Esc
then :/listen.owner
(to find it) then i
(to change)
-> UNCOMMENT the listen.owner = nobody
AND listen.group = nobody
lines
-> Hit Esc
then type :/user =
then i
-> change user = apache
TO user = nginx
-> AND change group = apache
TO group = nginx
-> Hit Esc
then :wq
(to save and quit)
-> systemctl start php-fpm.service
(now you will have a php-fpm.sock file)
SECOND, you configure your server {}
block in your /etc/nginx/nginx.conf
file. Then run:systemctl restart nginx.service
FINALLY, create a new .php file in your /usr/share/nginx/html directory for your Nginx server to serve up via the internet browser as a test.
-> vi /usr/share/nginx/html/mytest.php
-> type o
-> <?php echo date("Y/m/d-l"); ?>
(PHP page will print date and day in browser)
-> Hit Esc
-> type :wq
(to save and quite VI editor)
-> open up a browser and go to: http://yourDomainOrIPAddress/mytest.php
(you should see the date and day printed)
For making a CORS request one must add headers to the request along with the same he needs to check of mode_header is enabled in Apache.
For enabling headers in Ubuntu:
sudo a2enmod headers
For php server to accept request from different origin use:

Simply put:
SELECT *
FROM TABLE_NAME
WHERE
dob > '1/21/2012'
Where 1/21/2012 is the date and you want all data, including that date.
SELECT *
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'
Use a between if you're selecting time between two dates
Well, In Mapreduce there are two important phrases called Mapper and reducer both are too important, but Reducer is mandatory. In some programs reducers are optional. Now come to your question. Shuffling and sorting are two important operations in Mapreduce. First Hadoop framework takes structured/unstructured data and separate the data into Key, Value.
Now Mapper program separate and arrange the data into keys and values to be processed. Generate Key 2 and value 2 values. This values should process and re arrange in proper order to get desired solution. Now this shuffle and sorting done in your local system (Framework take care it) and process in local system after process framework cleanup the data in local system. Ok
Here we use combiner and partition also to optimize this shuffle and sort process. After proper arrangement, those key values passes to Reducer to get desired Client's output. Finally Reducer get desired output.
K1, V1 -> K2, V2 (we will write program Mapper), -> K2, V' (here shuffle and soft the data) -> K3, V3 Generate the output. K4,V4.
Please note all these steps are logical operation only, not change the original data.
Your question: What is the purpose of shuffling and sorting phase in the reducer in Map Reduce Programming?
Short answer: To process the data to get desired output. Shuffling is aggregate the data, reduce is get expected output.
The term upstream also has some unambiguous meaning as comes to the suite of GIT tools, especially relative to tracking
For example :
$git rev-list --count --left-right "@{upstream}"...HEAD >4 12
will print (the last cached value of) the number of commits behind (left) and ahead (right) of your current working branch, relative to the (if any) currently tracking remote branch for this local branch. It will print an error message otherwise:
>error: No upstream branch found for ''
origin
(your forked repo on github) and upstream
(the repo on github you forked from). Those are just interchangeable names, only the 'git@...' url identifies them.Your
.git/config
reads :[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = [email protected]:myusername/reponame.git [remote "upstream"] fetch = +refs/heads/*:refs/remotes/upstream/* url = [email protected]:authorname/reponame.git
it is 'the branch' (if any) on 'said remote', which is tracking the 'current branch' on your 'local repository'.
It's the branch you fetch/pull from whenever you issue a plain
git fetch
/git pull
, without arguments.
Let's say want to set the remote branch origin/master to be the tracking branch for the local master branch you've checked out. Just issue :
$ git branch --set-upstream master origin/master > Branch master set up to track remote branch master from origin.
This adds 2 parameters in
.git/config
:[branch "master"] remote = origin merge = refs/heads/master
now try (provided 'upstream' remote has a 'dev' branch)
$ git branch --set-upstream master upstream/dev > Branch master set up to track remote branch dev from upstream.
.git/config
now reads:[branch "master"] remote = upstream merge = refs/heads/dev
-u --set-upstream
For every branch that is up to date or successfully pushed, add upstream (tracking) reference, used by argument-less git-pull(1) and other commands. For more information, see
branch.<name>.merge
in git-config(1).branch.<name>.merge
Defines, together with
branch.<name>.remote
, the upstream branch for the given branch. It tells git fetch/git pull/git rebase which branch to merge and can also affect git push (see push.default). \ (...)branch.<name>.remote
When in branch < name >, it tells git fetch and git push which remote to fetch from/push to. It defaults to origin if no remote is configured. origin is also used if you are not on any branch.
take a look at git-config(1)
Manual Page
git config --global push.default upstream git config --global push.default tracking (deprecated)
This is to prevent accidental pushes to branches which you’re not ready to push yet.
I think the author's of React Router (v4) just added that withRouter HOC to appease certain users. However, I believe the better approach is to just use render prop and make a simple PropsRoute component that passes those props. This is easier to test as you it doesn't "connect" the component like withRouter does. Have a bunch of nested components wrapped in withRouter and it's not going to be fun. Another benefit is you can also use this pass through whatever props you want to the Route. Here's the simple example using render prop. (pretty much the exact example from their website https://reacttraining.com/react-router/web/api/Route/render-func) (src/components/routes/props-route)
import React from 'react';
import { Route } from 'react-router';
export const PropsRoute = ({ component: Component, ...props }) => (
<Route
{ ...props }
render={ renderProps => (<Component { ...renderProps } { ...props } />) }
/>
);
export default PropsRoute;
usage: (notice to get the route params (match.params) you can just use this component and those will be passed for you)
import React from 'react';
import PropsRoute from 'src/components/routes/props-route';
export const someComponent = props => (<PropsRoute component={ Profile } />);
also notice that you could pass whatever extra props you want this way too
<PropsRoute isFetching={ isFetchingProfile } title="User Profile" component={ Profile } />
Swift 4 extension using explicit constraints:
import UIKit.UIView
extension UIView {
public func addSubview(_ subview: UIView, stretchToFit: Bool = false) {
addSubview(subview)
if stretchToFit {
subview.translatesAutoresizingMaskIntoConstraints = false
leftAnchor.constraint(equalTo: subview.leftAnchor).isActive = true
rightAnchor.constraint(equalTo: subview.rightAnchor).isActive = true
topAnchor.constraint(equalTo: subview.topAnchor).isActive = true
bottomAnchor.constraint(equalTo: subview.bottomAnchor).isActive = true
}
}
}
Usage:
parentView.addSubview(childView) // won't resize (default behavior unchanged)
parentView.addSubview(childView, stretchToFit: false) // won't resize
parentView.addSubview(childView, stretchToFit: true) // will resize
I thought I had the same problem but actually I have a slight difference that makes the problem easier to solve. For others looking at this question it's worth checking the format of your input list. In my case the numbers are initially floats not strings as in the question:
a = [['a', 1.2, 4.2], ['b', 70, 0.03], ['x', 5, 0]]
but by processing the list too much before creating the dataframe I lose the types and everything becomes a string.
Creating the data frame via a numpy array
df = pd.DataFrame(np.array(a))
df
Out[5]:
0 1 2
0 a 1.2 4.2
1 b 70 0.03
2 x 5 0
df[1].dtype
Out[7]: dtype('O')
gives the same data frame as in the question, where the entries in columns 1 and 2 are considered as strings. However doing
df = pd.DataFrame(a)
df
Out[10]:
0 1 2
0 a 1.2 4.20
1 b 70.0 0.03
2 x 5.0 0.00
df[1].dtype
Out[11]: dtype('float64')
does actually give a data frame with the columns in the correct format
I face the same problem. After reading numerous posts, I would like to introduce the following solution I finally chose over many other methods (e.g. use urllib
, httpimport
, clone from GitHub, package the modules for installation, etc). The solution utilizes Google Drive API (official doc) for proper authorization.
id=
" - the file id assigned by Google Drive!pip install pydrive # Package to use Google Drive API - not installed in Colab VM by default
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth # Other necessary packages
from oauth2client.client import GoogleCredentials
auth.authenticate_user() # Follow prompt in the authorization process
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)
your_module = drive.CreateFile({"id": "your_module_file_id"}) # "your_module_file_id" is the part after "id=" in the shareable link
your_module.GetContentFile("your_module_file_name.py") # Save the .py module file to Colab VM
import your_module_file_name # Ready to import. Don't include".py" part, of course :)
Last but not least, I should credit the original contributor of this approach. That post might have some typo in the code as it triggered an error when I tried it. After more reading and troubleshooting my code snippets above worked (as of today on Colab VM OS: Linux 4.14.79).
I know this is late but it might be of some use:
echo "<pre>";
print_r($array);
echo "</pre>";
Are you removing or splitting? This will remove all the non-numeric characters.
myStr = myStr.replaceAll( "[^\\d]", "" )
The developer advocate for YouTube gave a talk about scaling Python at PyCon 2012, which is also relevant to scaling Django.
YouTube has more than a billion users, and YouTube is built on Python.
You don't need to copy a Python string. They are immutable, and the copy
module always returns the original in such cases, as do str()
, the whole string slice, and concatenating with an empty string.
Moreover, your 'hello'
string is interned (certain strings are). Python deliberately tries to keep just the one copy, as that makes dictionary lookups faster.
One way you could work around this is to actually create a new string, then slice that string back to the original content:
>>> a = 'hello'
>>> b = (a + '.')[:-1]
>>> id(a), id(b)
(4435312528, 4435312432)
But all you are doing now is waste memory. It is not as if you can mutate these string objects in any way, after all.
If all you wanted to know is how much memory a Python object requires, use sys.getsizeof()
; it gives you the memory footprint of any Python object.
For containers this does not include the contents; you'd have to recurse into each container to calculate a total memory size:
>>> import sys
>>> a = 'hello'
>>> sys.getsizeof(a)
42
>>> b = {'foo': 'bar'}
>>> sys.getsizeof(b)
280
>>> sys.getsizeof(b) + sum(sys.getsizeof(k) + sys.getsizeof(v) for k, v in b.items())
360
You can then choose to use id()
tracking to take an actual memory footprint or to estimate a maximum footprint if objects were not cached and reused.
del df
will not be deleted if there are any reference to the df
at the time of deletion. So you need to to delete all the references to it with del df
to release the memory.
So all the instances bound to df should be deleted to trigger garbage collection.
Use objgragh to check which is holding onto the objects.
This can be easily accomplished using PHP 'fmod' function. The code below is specific to 10 but you can change it to any number.
$num=97;
$r=fmod($num,10);
$r=10-$r;
$r=$num+$r;
return $r;
OUTPUT: 100

I needed something similar, the ability to click on a set of icons to indicate a choice, or a text-based choice and have that update the model (2-way-binding) with the represented value and to also a way to indicate which was selected visually. I created an AngularJS directive for it, since it needed to be flexible enough to handle any HTML element being clicked on to indicate a choice.
<ul ng-repeat="vote in votes" ...>
<li data-choice="selected" data-value="vote.id">...</li>
</ul>
Here's a nice easy way I found:
h <- hist(g, breaks = 10, density = 10,
col = "lightgray", xlab = "Accuracy", main = "Overall")
xfit <- seq(min(g), max(g), length = 40)
yfit <- dnorm(xfit, mean = mean(g), sd = sd(g))
yfit <- yfit * diff(h$mids[1:2]) * length(g)
lines(xfit, yfit, col = "black", lwd = 2)
In case you update the image multiple times and it gets CACHED and does not update, add a random string at the end:
// update image in dom
$('#target').attr('src', 'https://example.com/img.jpg?rand=' + Math.random());
You have stumbled over the general problem with encodings: How can I tell in which encoding a file is?
Answer: You can't unless the file format provides for this. XML, for example, begins with:
<?xml encoding="utf-8"?>
This header was carefully chosen so that it can be read no matter the encoding. In your case, there is no such hint, hence neither your editor nor Python has any idea what is going on. Therefore, you must use the codecs
module and use codecs.open(path,mode,encoding)
which provides the missing bit in Python.
As for your editor, you must check if it offers some way to set the encoding of a file.
The point of UTF-8 is to be able to encode 21-bit characters (Unicode) as an 8-bit data stream (because that's the only thing all computers in the world can handle). But since most OSs predate the Unicode era, they don't have suitable tools to attach the encoding information to files on the hard disk.
The next issue is the representation in Python. This is explained perfectly in the comment by heikogerlach. You must understand that your console can only display ASCII. In order to display Unicode or anything >= charcode 128, it must use some means of escaping. In your editor, you must not type the escaped display string but what the string means (in this case, you must enter the umlaut and save the file).
That said, you can use the Python function eval() to turn an escaped string into a string:
>>> x = eval("'Capit\\xc3\\xa1n\\n'")
>>> x
'Capit\xc3\xa1n\n'
>>> x[5]
'\xc3'
>>> len(x[5])
1
As you can see, the string "\xc3" has been turned into a single character. This is now an 8-bit string, UTF-8 encoded. To get Unicode:
>>> x.decode('utf-8')
u'Capit\xe1n\n'
Gregg Lind asked: I think there are some pieces missing here: the file f2 contains: hex:
0000000: 4361 7069 745c 7863 335c 7861 316e Capit\xc3\xa1n
codecs.open('f2','rb', 'utf-8')
, for example, reads them all in a separate chars (expected) Is there any way to write to a file in ASCII that would work?
Answer: That depends on what you mean. ASCII can't represent characters > 127. So you need some way to say "the next few characters mean something special" which is what the sequence "\x" does. It says: The next two characters are the code of a single character. "\u" does the same using four characters to encode Unicode up to 0xFFFF (65535).
So you can't directly write Unicode to ASCII (because ASCII simply doesn't contain the same characters). You can write it as string escapes (as in f2); in this case, the file can be represented as ASCII. Or you can write it as UTF-8, in which case, you need an 8-bit safe stream.
Your solution using decode('string-escape')
does work, but you must be aware how much memory you use: Three times the amount of using codecs.open()
.
Remember that a file is just a sequence of bytes with 8 bits. Neither the bits nor the bytes have a meaning. It's you who says "65 means 'A'". Since \xc3\xa1
should become "à" but the computer has no means to know, you must tell it by specifying the encoding which was used when writing the file.
You can try a rebase --interactive
session to amend your old commit (provided you did not already push those commits to another repo).
Sometimes the thing fixed in b.2. cannot be amended to the not-quite perfect commit it fixes, because that commit is buried deeply in a patch series.
That is exactly what interactive rebase is for: use it after plenty of "a"s and "b"s, by rearranging and editing commits, and squashing multiple commits into one.Start it with the last commit you want to retain as-is:
git rebase -i <after-this-commit>
An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit.
You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:
pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...
The oneline descriptions are purely for your pleasure; git rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.
By replacing the command "pick" with the command "edit", you can tell git rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.
Either use
SELECT IF(field1 IS NULL or field1 = '', 'empty', field1) as field1
from tablename
or
SELECT case when field1 IS NULL or field1 = ''
then 'empty'
else field1
end as field1
from tablename
If you only want to check for null
and not for empty strings then you can also use ifnull()
or coalesce(field1, 'empty')
. But that is not suitable for empty strings.
Javascript is duck typed, so you can create a small structure.
function myFunction(value1,value2,value3)
{
var myObject = new Object();
myObject.value2 = somevalue2;
myObject.value3 = somevalue3;
return myObject;
}
var value = myFunction("1",value2,value3);
if(value.value2 && value.value3)
{
//Do some stuff
}
WARNING:
git clean -f
will remove untracked files, meaning they're gone for good since they aren't stored in the repository. Make sure you really want to remove all untracked files before doing this.
Try this and see git clean -f
.
git reset --hard
will not remove untracked files, where as git-clean
will remove any files from the tracked root directory that are not under Git tracking.
Alternatively, as @Paul Betts said, you can do this (beware though - that removes all ignored files too)
git clean -df
git clean -xdf
CAUTION! This will also delete ignored filesWhat about using CSS3 transform
property and use scale
which ill give a zoom like effect, this can be done like so,
HTML
<div class="thumbnail">
<div class="image">
<img src="http://placehold.it/320x240" alt="Some awesome text"/>
</div>
</div>
CSS
.thumbnail {
width: 320px;
height: 240px;
}
.image {
width: 100%;
height: 100%;
}
.image img {
-webkit-transition: all 1s ease; /* Safari and Chrome */
-moz-transition: all 1s ease; /* Firefox */
-ms-transition: all 1s ease; /* IE 9 */
-o-transition: all 1s ease; /* Opera */
transition: all 1s ease;
}
.image:hover img {
-webkit-transform:scale(1.25); /* Safari and Chrome */
-moz-transform:scale(1.25); /* Firefox */
-ms-transform:scale(1.25); /* IE 9 */
-o-transform:scale(1.25); /* Opera */
transform:scale(1.25);
}
Here's a demo fiddle. I removed some of the element to make it simpler, you can always add overflow hidden to the .image
to hide the overflow of the scaled image.
zoom
property only works in IE
There are a few functions like:
NSStringFromCGPoint
NSStringFromCGSize
NSStringFromCGRect
NSStringFromCGAffineTransform
NSStringFromUIEdgeInsets
An example:
NSLog(@"rect1: %@", NSStringFromCGRect(rect1));
If the error happens to be because your data has NAs, then you need to set the glm() function options of how you would like to treat the NA cases. More information on this is found in a relevant post here: https://stats.stackexchange.com/questions/46692/how-the-na-values-are-treated-in-glm-in-r
var data=[{'com':'something'},{'com':'some other thing'}];
$.each(data, function() {
$.each(this, function(key, val){
alert(val);//here data
alert (key); //here key
});
});
I agree with Cat Plus Plus's answer. However, if you know this will only be used on Unix-like OSes, you can use external calls to the shell commands mkdir
, chmod
, and chown
. Make sure to pass extra flags to recursively affect directories:
>>> import subprocess
>>> subprocess.check_output(['mkdir', '-p', 'first/second/third'])
# Equivalent to running 'mkdir -p first/second/third' in a shell (which creates
# parent directories if they do not yet exist).
>>> subprocess.check_output(['chown', '-R', 'dail:users', 'first'])
# Recursively change owner to 'dail' and group to 'users' for 'first' and all of
# its subdirectories.
>>> subprocess.check_output(['chmod', '-R', 'g+w', 'first'])
# Add group write permissions to 'first' and all of its subdirectories.
EDIT I originally used commands
, which was a bad choice since it is deprecated and vulnerable to injection attacks. (For example, if a user gave input to create a directory called first/;rm -rf --no-preserve-root /;
, one could potentially delete all directories).
EDIT 2 If you are using Python less than 2.7, use check_call
instead of check_output
. See the subprocess
documentation for details.
You can use GetExitCodeProcess
. It will return STILL_ACTIVE
(259) if the process is still running (or if it happened to exit with that exit code :( ).
In DBeaver (or other editors) the script file you're working can prompt to save as UTF8 and that will change the char:
–
into
–
or
–
In WinForms, ValueMember
and DisplayMember
are used when data-binding the list. If you're not data-binding, then you can add any arbitrary object as a ListItem
.
The catch to that is that, in order to display the item, ToString()
will be called on it. Thus, it is highly recommended that you only add objects to the ListBox where calling ToString()
will result in meaningful output.
For that you need to add change listener (a DocumentListener
which reacts for change in the text) for your JTextField
, and within actionPerformed()
, you need to update the loginButton
to enabled/disabled depending on the whether the JTextfield
is empty or not.
Below is what I found from this thread.
yourJTextField.getDocument().addDocumentListener(new DocumentListener() {
public void changedUpdate(DocumentEvent e) {
changed();
}
public void removeUpdate(DocumentEvent e) {
changed();
}
public void insertUpdate(DocumentEvent e) {
changed();
}
public void changed() {
if (yourJTextField.getText().equals("")){
loginButton.setEnabled(false);
}
else {
loginButton.setEnabled(true);
}
}
});
This seems unnecessary, but VBA is a strange place. If you declare an array variable, then set it using Array()
then pass the variable into your function, VBA will be happy.
Sub test()
Dim fString As String
Dim arr() As Variant
arr = Array("foo", "bar")
fString = processArr(arr)
End Sub
Also your function processArr()
could be written as:
Function processArr(arr() As Variant) As String
processArr = Replace(Join(arr()), " ", "")
End Function
If you are into the whole brevity thing.
If you want to add a dynamic class to your host element, you may combine your HostBinding
with a getter as
@HostBinding('class') get class() {
return aComponentVariable
}
Stackblitz demo at https://stackblitz.com/edit/angular-dynamic-hostbinding
for any textview at your activity (or create fake empty textfiew with android:layout_width="0dp" android:layout_height="0dp" ) and add for this textview next: android:textIsSelectable="true"
The only way I know of doing it is by omitting the parameter. The only way to omit the parameter is to rearrange the parameter list so that the one you want to omit is after the parameters that you HAVE to set. For example:
function foo($blah, $y = "some other value", $x = "some value")
Then you can call foo like:
foo("blah", "test");
This will result in:
$blah = "blah";
$y = "test";
$x = "some value";
Try to check the length of the selector, if it returns you something then the element must exists else not.
if( $('#selector').length ) // use this if you are using id to check
{
// it exists
}
if( $('.selector').length ) // use this if you are using class to check
{
// it exists
}
