You can use it to transform some aggregate functions into analytic:
SELECT MAX(date)
FROM mytable
will return 1
row with a single maximum,
SELECT MAX(date) OVER (ORDER BY id)
FROM mytable
will return all rows with a running maximum.
This article here nicely explains it. Essentially, you can look at it as such:
CREATE TABLE t AS
SELECT 'a' v FROM dual UNION ALL
SELECT 'a' FROM dual UNION ALL
SELECT 'a' FROM dual UNION ALL
SELECT 'b' FROM dual UNION ALL
SELECT 'c' FROM dual UNION ALL
SELECT 'c' FROM dual UNION ALL
SELECT 'd' FROM dual UNION ALL
SELECT 'e' FROM dual;
SELECT
v,
ROW_NUMBER() OVER (ORDER BY v) row_number,
RANK() OVER (ORDER BY v) rank,
DENSE_RANK() OVER (ORDER BY v) dense_rank
FROM t
ORDER BY v;
The above will yield:
+---+------------+------+------------+
| V | ROW_NUMBER | RANK | DENSE_RANK |
+---+------------+------+------------+
| a | 1 | 1 | 1 |
| a | 2 | 1 | 1 |
| a | 3 | 1 | 1 |
| b | 4 | 4 | 2 |
| c | 5 | 5 | 3 |
| c | 6 | 5 | 3 |
| d | 7 | 7 | 4 |
| e | 8 | 8 | 5 |
+---+------------+------+------------+
In words
ROW_NUMBER()
attributes a unique value to each rowRANK()
attributes the same row number to the same value, leaving "holes"DENSE_RANK()
attributes the same row number to the same value, leaving no "holes"As of my understanding Partition By is almost identical to Group By, but with the following differences:
That group by actually groups the result set returning one row per group, which results therefore in SQL Server only allowing in the SELECT list aggregate functions or columns that are part of the group by clause (in which case SQL Server can guarantee that there are unique results for each group).
Consider for example MySQL which allows to have in the SELECT list columns that are not defined in the Group By clause, in which case one row is still being returned per group, however if the column doesn't have unique results then there is no guarantee what will be the output!
But with Partition By, although the results of the function are identical to the results of an aggregate function with Group By, still you are getting the normal result set, which means that one is getting one row per underlying row, and not one row per group, and because of this one can have columns that are not unique per group in the SELECT list.
So as a summary, Group By would be best when needs an output of one row per group, and Partition By would be best when one needs all the rows but still wants the aggregate function based on a group.
Of course there might also be performance issues, see http://social.msdn.microsoft.com/Forums/ms-MY/transactsql/thread/0b20c2b5-1607-40bc-b7a7-0c60a2a55fba.
SELECT tab.*,
row_number() OVER () as rnum
FROM tab;
Here's the relevant section in the docs.
P.S. This, in fact, fully matches the answer in the referenced question.
Since 0.14.1, you can now do nlargest
and nsmallest
on a groupby
object:
In [23]: df.groupby('id')['value'].nlargest(2)
Out[23]:
id
1 2 3
1 2
2 6 4
5 3
3 7 1
4 8 1
dtype: int64
There's a slight weirdness that you get the original index in there as well, but this might be really useful depending on what your original index was.
If you're not interested in it, you can do .reset_index(level=1, drop=True)
to get rid of it altogether.
(Note: From 0.17.1 you'll be able to do this on a DataFrameGroupBy too but for now it only works with Series
and SeriesGroupBy
.)
ROWS UNBOUNDED PRECEDING
is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY
it defines the window on which the result is calculated.
Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.
Starting and ending rows might be fixed or relative to the current row based on the following keywords:
Possible kinds of calculation include:
So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING)
results in a Cumulative Sum or Running Total
11 -> 11
2 -> 11 + 2 = 13
3 -> 13 + 3 (or 11+2+3) = 16
44 -> 16 + 44 (or 11+2+3+44) = 60
If the order of element is not important, you can
select
id, elem, row_number() over (partition by id) as nr
from (
select
id,
unnest(string_to_array(elements, ',')) AS elem
from myTable
) a
I think, this example suggests a small nuance on how the partitioning works and how group by works. My example is from Oracle 12, if my example happens to be a compiling bug.
I tried :
SELECT t.data_key
, SUM ( CASE when t.state = 'A' THEN 1 ELSE 0 END)
OVER (PARTITION BY t.data_key) count_a_rows
, SUM ( CASE when t.state = 'B' THEN 1 ELSE 0 END)
OVER (PARTITION BY t.data_key) count_b_rows
, SUM ( CASE when t.state = 'C' THEN 1 ELSE 0 END)
OVER (PARTITION BY t.data_key) count_c_rows
, COUNT (1) total_rows
from mytable t
group by t.data_key ---- This does not compile as the compiler feels that t.state isn't in the group by and doesn't recognize the aggregation I'm looking for
This however works as expected :
SELECT distinct t.data_key
, SUM ( CASE when t.state = 'A' THEN 1 ELSE 0 END)
OVER (PARTITION BY t.data_key) count_a_rows
, SUM ( CASE when t.state = 'B' THEN 1 ELSE 0 END)
OVER (PARTITION BY t.data_key) count_b_rows
, SUM ( CASE when t.state = 'C' THEN 1 ELSE 0 END)
OVER (PARTITION BY t.data_key) count_c_rows
, COUNT (1) total_rows
from mytable t;
Producing the number of elements in each state based on the external key "data_key". So, if, data_key = 'APPLE' had 3 rows with state 'A', 2 rows with state 'B', a row with state 'C', the corresponding row for 'APPLE' would be 'APPLE', 3, 2, 1, 6.
I usually use SHA1 and salt with the user ID (or some other user-specific piece of information), and sometimes I additionally use a constant salt (so I have 2 parts to the salt).
SHA1 is now also considered somewhat compromised, but to a far lesser degree than MD5. By using a salt (any salt), you're preventing the use of a generic rainbow table to attack your hashes (some people have even had success using Google as a sort of rainbow table by searching for the hash). An attacker could conceivably generate a rainbow table using your salt, so that's why you should include a user-specific salt. That way, they will have to generate a rainbow table for each and every record in your system, not just one for your entire system! With that type of salting, even MD5 is decently secure.
If "sudo apt-get install php-curl" command doesnt work and display error We should run this code before install curl.
No, there is no better way.
Actually you have an error in your pattern. What you want is:
DecimalFormat df = new DecimalFormat("#.00");
Note the "00"
, meaning exactly two decimal places.
If you use "#.##"
(#
means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d);
prints just "3"
, not "3.00"
.
Try this:
MessageBox.Show("Some text", "Some title",
MessageBoxButtons.OK, MessageBoxIcon.Error);
You could also use function exposed by the axes object of the scatter plot
scatter = plt.scatter(x, y)
ax = scatter.axes
ax.invert_xaxis()
ax.invert_yaxis()
As Greg Hewgill said, the typedef means you no longer have to write struct
all over the place. That not only saves keystrokes, it also can make the code cleaner since it provides a smidgen more abstraction.
Stuff like
typedef struct {
int x, y;
} Point;
Point point_new(int x, int y)
{
Point a;
a.x = x;
a.y = y;
return a;
}
becomes cleaner when you don't need to see the "struct" keyword all over the place, it looks more as if there really is a type called "Point" in your language. Which, after the typedef
, is the case I guess.
Also note that while your example (and mine) omitted naming the struct
itself, actually naming it is also useful for when you want to provide an opaque type. Then you'd have code like this in the header, for instance:
typedef struct Point Point;
Point * point_new(int x, int y);
and then provide the struct
definition in the implementation file:
struct Point
{
int x, y;
};
Point * point_new(int x, int y)
{
Point *p;
if((p = malloc(sizeof *p)) != NULL)
{
p->x = x;
p->y = y;
}
return p;
}
In this latter case, you cannot return the Point by value, since its definition is hidden from users of the header file. This is a technique used widely in GTK+, for instance.
UPDATE Note that there are also highly-regarded C projects where this use of typedef
to hide struct
is considered a bad idea, the Linux kernel is probably the most well-known such project. See Chapter 5 of The Linux Kernel CodingStyle document for Linus' angry words. :) My point is that the "should" in the question is perhaps not set in stone, after all.
You (or Joomla) is likely including this file multiple times. Enclose your function in a conditional block:

If you need quick way to convert strings into bools (that functions with most strings) try.
def conv2bool(arg):
try:

return res # or do some more processing with arg if res is false
it's my understanding that target = whatever
will look for a frame/window with that name. If not found, it will open up a new window with that name. If whatever == "_new"
, it will appear just as if you used _blank
except.....
Using one of the reserved target names will bypass the "looking" phase. So, target = "_blank"
on a dozen links will open up a dozen blank windows, but target = whatever
on a dozen links will only open up one window. target = "_new"
on a dozen links may give inconstant behavior. I haven't tried it on several browsers, but should only open up one window.
At least this is how I interpret the rules.
For any of you calling back to the same server for your IFRAME, pass this simple header inside the IFRAME page:
Content-Security-Policy: frame-ancestors 'self'
Or, add this to your web server's CSP configuration.
After adding the cordova-plugin-whitelist, you must tell your application to allow access all the web-page links or specific links, if you want to keep it specific.
You can simply add this to your config.xml, which can be found in your application's root directory:
Recommended in the documentation:
<allow-navigation href="http://example.com/*" />
or:
<allow-navigation href="http://*/*" />
From the plugin's documentation:
Navigation Whitelist
Controls which URLs the WebView itself can be navigated to. Applies to top-level navigations only.
Quirks: on Android it also applies to iframes for non-http(s) schemes.
By default, navigations only to file:// URLs, are allowed. To allow other other URLs, you must add tags to your config.xml:
<!-- Allow links to example.com --> <allow-navigation href="http://example.com/*" /> <!-- Wildcards are allowed for the protocol, as a prefix to the host, or as a suffix to the path --> <allow-navigation href="*://*.example.com/*" /> <!-- A wildcard can be used to whitelist the entire network, over HTTP and HTTPS. *NOT RECOMMENDED* --> <allow-navigation href="*" /> <!-- The above is equivalent to these three declarations --> <allow-navigation href="http://*/*" /> <allow-navigation href="https://*/*" /> <allow-navigation href="data:*" />
I need to somehow query Google and ask: Is this access token valid for [email protected]?
No. All you need is request standard login with Federated Login for Google Account Users from your API domain. And only after that you could compare "persistent user ID" with one you have from 'public interface'.
The value of realm is used on the Google Federated Login page to identify the requesting site to the user. It is also used to determine the value of the persistent user ID returned by Google.
So you need be from same domain as 'public interface'.
And do not forget that user needs to be sure that your API could be trusted ;) So Google will ask user if it allows you to check for his identity.
I am not experiented .But i think XmlReader is unnecessary.
It is very hard to use.
XElement is very easy to use.
If you need performance ( faster ) you must change file format and use StreamReader and StreamWriter classes.
This is going to sound really cheesy, but it's the best way I've been able to keep the terms straight in my head:
Declaration: Picture Thomas Jefferson giving a speech... "I HEREBY DECLARE THAT THIS FOO EXISTS IN THIS SOURCE CODE!!!"
Definition: picture a dictionary, you are looking up Foo and what it actually means.
you can follow the below command to install using the wheel file at your local
pip install /users/arpansaini/Downloads/h5py-3.0.0-cp39-cp39-macosx_10_9_x86_64.whl
in webkit you need to set the width to a different value, then you can set it back to the initial value
If you want to remove a "database is locked" error then follow these steps:
Another option is to add another tag with flex: auto
style in between your tags that you want to fill in the remaining space.
https://jsfiddle.net/tsey5qu4/
The HTML:
<div class="parent">
<div class="left">Left</div>
<div class="fill-remaining-space"></div>
<div class="right">Right</div>
</div>
The CSS:
.fill-remaining-space {
flex: auto;
}
This is equivalent to flex: 1 1 auto, which absorbs any extra space along the main axis.
this.myService.getConfig().subscribe(
(res) => console.log(res),
(err) => console.log(err),
() => console.log('done!')
);
This is how you generate the samples on a modern C++ compiler.
#include <random>
...
std::mt19937 generator;
double mean = 0.0;
double stddev = 1.0;
std::normal_distribution<double> normal(mean, stddev);
cerr << "Normal: " << normal(generator) << endl;
Deadlocks will only occur when you have two or more locks that can be aquired at the same time and they are grabbed in different order.
Ways to avoid having deadlocks are:
In your code you aren't using jquery, so, if you want to use it, yo need something like...
$('#foo').css({'background-color' : 'red', 'color' : 'white', 'font-size' : '44px'});
Other way, if you are not using jquery, you need to do ...
document.getElementById('foo').style = 'background-color: red; color: white; font-size: 44px';
Use a custom comparator:
Collections.sort(nodeList, new Comparator<DataNode>(){
public int compare(DataNode o1, DataNode o2){
if(o1.degree == o2.degree)
return 0;
return o1.degree < o2.degree ? -1 : 1;
}
});
It is ternary operator, like an if/else statement.
if(a > b) {
what to do;
}
else {
what to do;
}
In ternary operator it is like that: condition ? what to do if condition is true : what to do if it is false;
(a > b) ? what to do if true : what to do if false;
As of React Native 0.4.2, View components have an onLayout
prop. Pass in a function that takes an event object. The event's nativeEvent
contains the view's layout.
<View onLayout={(event) => {
var {x, y, width, height} = event.nativeEvent.layout;
}} />
The onLayout
handler will also be invoked whenever the view is resized.
The main caveat is that the onLayout
handler is first invoked one frame after your component has mounted, so you may want to hide your UI until you have computed your layout.
In Java 8:
Arrays.stream(arr).iterator();
An abstract class is a class that is only partially implemented by the programmer. It may contain one or more abstract methods. An abstract method is simply a function definition that serves to tell the programmer that the method must be implemented in a child class.
There is good explanation of that here.

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.
My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

How would you check if a variable is a dictionary in Python?
This is an excellent question, but it is unfortunate that the most upvoted answer leads with a poor recommendation, type(obj) is dict
.
(Note that you should also not use dict
as a variable name - it's the name of the builtin object.)
If you are writing code that will be imported and used by others, do not presume that they will use the dict builtin directly - making that presumption makes your code more inflexible and in this case, create easily hidden bugs that would not error the program out.
I strongly suggest, for the purposes of correctness, maintainability, and flexibility for future users, never having less flexible, unidiomatic expressions in your code when there are more flexible, idiomatic expressions.
is
is a test for object identity. It does not support inheritance, it does not support any abstraction, and it does not support the interface.
So I will provide several options that do.
This is the first recommendation I would make, because it allows for users to supply their own subclass of dict, or a OrderedDict
, defaultdict
, or Counter
from the collections module:
if isinstance(any_object, dict):
But there are even more flexible options.
from collections.abc import Mapping
if isinstance(any_object, Mapping):
This allows the user of your code to use their own custom implementation of an abstract Mapping, which also includes any subclass of dict
, and still get the correct behavior.
You commonly hear the OOP advice, "program to an interface".
This strategy takes advantage of Python's polymorphism or duck-typing.
So just attempt to access the interface, catching the specific expected errors (AttributeError
in case there is no .items
and TypeError
in case items
is not callable) with a reasonable fallback - and now any class that implements that interface will give you its items (note .iteritems()
is gone in Python 3):
try:
items = any_object.items()
except (AttributeError, TypeError):
non_items_behavior(any_object)
else: # no exception raised
for item in items: ...
Perhaps you might think using duck-typing like this goes too far in allowing for too many false positives, and it may be, depending on your objectives for this code.
Don't use is
to check types for standard control flow. Use isinstance
, consider abstractions like Mapping
or MutableMapping
, and consider avoiding type-checking altogether, using the interface directly.

A simple way to convert dataframe to numpy array:
import pandas as pd
df = pd.DataFrame({"A": [1, 2], "B": [3, 4]})
df_to_array = df.to_numpy()
array([[1, 3],
[2, 4]])
Use of to_numpy is encouraged to preserve consistency.

Suspend the process with CTRL+Z then use the command bg
to resume it in background. For example:
sleep 60
^Z #Suspend character shown after hitting CTRL+Z
[1]+ Stopped sleep 60 #Message showing stopped process info
bg #Resume current job (last job stopped)
More about job control and bg
usage in bash
manual page:
JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.
EDIT
To start a process where you can even kill the terminal and it still carries on running
nohup [command] [-args] > [filename] 2>&1 &
e.g.
nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &
To just ignore the output (not very wise) change the filename to /dev/null
To get the error message set to a different file change the &1
to a filename.
In addition: You can use the jobs
command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1
or kill %2
with the number being the index of the process.
Common confusing issue here is that we have 2 different css properties: word-wrap
and word-break
.
Then on top of that, word-wrap has an option called break-word
.. Easy to mix-up :-)
Usually this worked for me, even inside a table:
word-break: break-word;
I changed the TextView's color to blue by using for example:
android:textColor="#3399FF"
in the xml file. How to make it underlined is explained here.
Then use its onClick property to specify a method (I'm guessing you could call setOnClickListener(this)
as another way), e.g.:
myTextView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
doSomething();
}
});
In that method, I can do whatever I want as normal, such as launch an intent. Note that you still have to do the normal myTextView.setMovementMethod(LinkMovementMethod.getInstance());
thing, like in your acitivity's onCreate() method.
I'm currently taking some legacy codebases and introducing minimal TypeScript changes to see if it helps our team. Depending on how strict you want to be with TypeScript, this may or may not be an option for you.
The most helpful way for us to get started was to extend our tsconfig.json
file with this property:
// tsconfig.json excerpt:
{
...
"compilerOptions": {
...
"allowJs": true,
...
}
...
}
This change lets our JS files that have JSDoc type hints get compiled. Also our IDEs (JetBrains IDEs and VS Code) can provide code-completion and Intellisense.

The difference between (R,)
and (1,R)
is literally the number of indices that you need to use. ones((1,R))
is a 2-D array that happens to have only one row. ones(R)
is a vector. Generally if it doesn't make sense for the variable to have more than one row/column, you should be using a vector, not a matrix with a singleton dimension.
For your specific case, there are a couple of options:
1) Just make the second argument a vector. The following works fine:
np.dot(M[:,0], np.ones(R))
2) If you want matlab like matrix operations, use the class matrix
instead of ndarray
. All matricies are forced into being 2-D arrays, and operator *
does matrix multiplication instead of element-wise (so you don't need dot). In my experience, this is more trouble that it is worth, but it may be nice if you are used to matlab.

You're probably trying to to update the same row of the target table multiple times. I just encountered the very same problem in a merge statement I developed. Make sure your update does not touch the same record more than once in the execution of the merge.
Another easy way to get epsilon is:
In [1]: 7./3 - 4./3 -1
Out[1]: 2.220446049250313e-16
I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse()
. std::reverse()
operates in place, so you may want to make a copy of the string first:
#include <algorithm>
#include <iostream>
#include <string>
int main()
{
std::string foo("foo");
std::string copy(foo);
std::cout << foo << '\n' << copy << '\n';
std::reverse(copy.begin(), copy.end());
std::cout << foo << '\n' << copy << '\n';
}
It doesn't work if you use Function, but works if you Sub. However, you cannot call a sub from a cell using formula.
Using functions with the ellipses is not very safe. If performance is not critical for log function consider using operator overloading as in boost::format. You could write something like this:
#include <sstream>
#include <boost/format.hpp>
#include <iostream>
using namespace std;
class formatted_log_t {
public:
formatted_log_t(const char* msg ) : fmt(msg) {}
~formatted_log_t() { cout << fmt << endl; }
template <typename T>
formatted_log_t& operator %(T value) {
fmt % value;
return *this;
}
protected:
boost::format fmt;
};
formatted_log_t log(const char* msg) { return formatted_log_t( msg ); }
// use
int main ()
{
log("hello %s in %d-th time") % "world" % 10000000;
return 0;
}
The following sample demonstrates possible errors with ellipses:
int x = SOME_VALUE;
double y = SOME_MORE_VALUE;
printf( "some var = %f, other one %f", y, x ); // no errors at compile time, but error at runtime. compiler do not know types you wanted
log( "some var = %f, other one %f" ) % y % x; // no errors. %f only for compatibility. you could write %1% instead.

The question of the post was avoiding e notation numbers and having the number as a plain number.
Therefore, if all is needed is to convert e (scientific) notation numbers to plain numbers (including in the case of fractional numbers) without loss of accuracy, then it is essential to avoid the use of the Math
object and other javascript number methods so that rounding does not occur when large numbers and large fractions are handled (which always happens due to the internal storage in binary format).
The following function converts e (scientific) notation numbers to plain numbers (including fractions) handling both large numbers and large fractions without loss of accuracy as it does not use the built-in math and number functions to handle or manipulate the number.
The function also handles normal numbers, so that a number that is suspected to become in an 'e' notation can be passed to the function for fixing.
The function should work with different locale decimal points.
94 test cases are provided.
For large e-notation numbers pass the number as a string.
Examples:
eToNumber("123456789123456789.111122223333444455556666777788889999e+50");
// output:
"12345678912345678911112222333344445555666677778888999900000000000000"
eToNumber("123.456123456789123456895e-80");
// output:
"0.00000000000000000000000000000000000000000000000000000000000000000000000000000123456123456789123456895"
eToNumber("123456789123456789.111122223333444455556666777788889999e-50");
// output:
"0.00000000000000000000000000000000123456789123456789111122223333444455556666777788889999"
Valid e-notation numbers in Javascript include the following:
123e1 ==> 1230
123E1 ==> 1230
123e+1 ==> 1230
123.e+1 ==> 1230
123e-1 ==> 12.3
0.1e-1 ==> 0.01
.1e-1 ==> 0.01
-123e1 ==> -1230

This can also be done with the Image
class of the PIL library:
from PIL import Image
import numpy as np
im_frame = Image.open(path_to_file + 'file.png')
np_frame = np.array(im_frame.getdata())
Note: The .getdata()
might not be needed - np.array(im_frame)
should also work
Here is your code for add data into both tableView:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var table1Text: UITextField!
@IBOutlet weak var table2Text: UITextField!
@IBOutlet weak var table1: UITableView!
@IBOutlet weak var table2: UITableView!
var table1Data = ["a"]
var table2Data = ["1"]
override func viewDidLoad() {
super.viewDidLoad()
}
@IBAction func addData(sender: AnyObject) {
//add your data into tables array from textField
table1Data.append(table1Text.text)
table2Data.append(table2Text.text)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
//reload your tableView
self.table1.reloadData()
self.table2.reloadData()
})
table1Text.resignFirstResponder()
table2Text.resignFirstResponder()
}
//delegate methods
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == table1 {
return table1Data.count
}else if tableView == table2 {
return table2Data.count
}
return Int()
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == table1 {
let cell = table1.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = table1Data[row]
return cell
}else if tableView == table2 {
let cell = table2.dequeueReusableCellWithIdentifier("Cell1", forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = table2Data[row]
return cell
}
return UITableViewCell()
}
}
And your result will be:
Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
IoC / DI to me is pushing out dependencies to the calling objects. Super simple.
The non-techy answer is being able to swap out an engine in a car right before you turn it on. If everything hooks up right (the interface), you are good.
According to the error message, you declared myLoc
as a pointer to an NSInteger (NSInteger *myLoc
) rather than an actual NSInteger (NSInteger myLoc
). It needs to be the latter.
string(byteslice) will convert byte slice to string, just know that it's not only simply type conversion, but also memory copy.
I use format, Number, 2 decimal places & tick ' use 1000 separater ', then go to 'File', 'Options', 'Advanced', scroll down to 'When calculating this workbook' and tick 'set precision as displayed'. You get an error message about losing accuracy, that's good as it means it is rounding to 2 decimal places. So much better than bothering with adding a needless ROUND function.
Transaction - is just a logically composed set of operations you want all together be either committed or rolled back.
Some might encounter this error (I got it while implementing PHP-MySQLi-JSON-Google Chart Example):
You called the draw() method with the wrong type of data rather than a DataTable or DataView.
The solution would be: replace jsapi and just use loader.js with:
google.charts.load('current', {packages: ['corechart']}) and
google.charts.setOnLoadCallback
-- according to the release notes --> The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader from now on.

If you would like to check in PHP , then you should do something like :
$query_s =mysql_query("SELECT YOURROWNAME from `YOURTABLENAME` where name = $name");
$ertom=mysql_fetch_array($query_s);
if ('' !== $ertom['YOURROWNAME']) {
//do your action
echo "It was filled";
} else {
echo "it was empty!";
}
To increase the heap size you can use the -Xmx argument when starting Java; e.g.
-Xmx256M
Try this one, should work:
cast((convert(bigint,b.tax_id)) as varchar(20))
Add Label (a QLabel) to the dialog where you want to show the image. This QLabel will actually display the image. Resize it to the size you want the image to appear.
Add the image to your resources in your project.
Now go into QLabel properties and select the image you added to resources for pixmap property. Make sure to check the next property scaledContents to shrink the image in the size you want to see it.
That's all, the image will now show up.
Well, you didn't specify which version of .Net you're using.
Assuming you have 3.5, another way is the ElementAt method:
var e = enumerable.ElementAt(0);
Unless C: is not the drive that windows booted from.
Parse the %SystemRoot% variable, it contains the location of the windows folder (i.e. c:\windows).
Handling listView scrolling using UP/ Down using.button
If someone is interested in handling listView one row up/down using button. then.
public View.OnClickListener onChk = new View.OnClickListener() {
public void onClick(View v) {
int index = list.getFirstVisiblePosition();
getListView().smoothScrollToPosition(index+1); // For increment.
}
});
Try this,
$('td').click(function(){
var row_index = $(this).parent().index();
var col_index = $(this).index();
});
If you need the index of table contain td then you can change it to
var row_index = $(this).parent('table').index();
First of all, you do not have to develop any form yourself : phpMyAdmin, depending on its configuration (i.e. config.inc.php
) will display an identification form, asking for a login and password.
To get that form, you should not use :
$cfg['Servers'][$i]['auth_type'] = 'config';
But you should use :
$cfg['Servers'][$i]['auth_type'] = 'cookie';
(At least, that's what I have on a server which prompts for login/password, using a form)
For more informations, you can take a look at the documentation :
'config'
authentication ($auth_type = 'config'
) is the plain old way: username and password are stored in config.inc.php.'cookie'
authentication mode ($auth_type = 'cookie'
) as introduced in 2.2.3 allows you to log in as any valid MySQL user with the help of cookies.
Username and password are stored in cookies during the session and password is deleted when it ends.
you can use those functions together with iferror
as a work around.
try =IFERROR(VALUE(A4),(CONCATENATE(A4)))
To have an output more similar to the raw console.log(obj)
I usually do use console.log('Status: ' + util.inspect(obj))
(JSON is slightly different).
It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.
Edit: This is what the forums say:
By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.
To disable:
/system/bin/bugmailer.sh must be deleted/renamed.
There should be a folder on your SD card called "bug reports".

You are not returning a response object from your view my_form_post
. The function ends with implicit return None
, which Flask does not like.
Make the function my_form_post
return an explicit response, for example
return 'OK'
at the end of the function.
Take a look at cat /proc/stat
grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'
EDIT please read comments before copy-paste this or using this for any serious work. This was not tested nor used, it's an idea for people who do not want to install a utility or for something that works in any distribution. Some people think you can "apt-get install" anything.
NOTE: this is not the current CPU usage, but the overall CPU usage in all the cores since the system bootup. This could be very different from the current CPU usage. To get the current value top (or similar tool) must be used.
Current CPU usage can be potentially calculated with:
awk '{u=$2+$4; t=$2+$4+$5; if (NR==1){u1=u; t1=t;} else print ($2+$4-u1) * 100 / (t-t1) "%"; }' \
<(grep 'cpu ' /proc/stat) <(sleep 1;grep 'cpu ' /proc/stat)
I did it by adding a point to my initial arrays. In this way I avoid defining self-made functions, and the linear extrapolation (in the example below: right extrapolation) looks ok.
import numpy as np
from scipy import interp as itp
xnew = np.linspace(0,1,51)
x1=xold[-2]
x2=xold[-1]
y1=yold[-2]
y2=yold[-1]
right_val=y1+(xnew[-1]-x1)*(y2-y1)/(x2-x1)
x=np.append(xold,xnew[-1])
y=np.append(yold,right_val)
f = itp(xnew,x,y)

You can overwrite the bootstrap colors, including the .navbar-inner
class, by targetting it in your own stylesheet as opposed to modifying the bootstrap.css stylesheet, like so:
.navbar-inner {
background-color: #2c2c2c; /* fallback color, place your own */
/* Gradients for modern browsers, replace as you see fit */
background-image: -moz-linear-gradient(top, #333333, #222222);
background-image: -ms-linear-gradient(top, #333333, #222222);
background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#333333), to(#222222));
background-image: -webkit-linear-gradient(top, #333333, #222222);
background-image: -o-linear-gradient(top, #333333, #222222);
background-image: linear-gradient(top, #333333, #222222);
background-repeat: repeat-x;
/* IE8-9 gradient filter */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#333333', endColorstr='#222222', GradientType=0);
}
You just have to modify all of those styles with your own and they will get picked up, like something like this for example, where i eliminate all gradient effects and just set a solid black background-color:
.navbar-inner {
background-color: #000; /* background color will be black for all browsers */
background-image: none;
background-repeat: no-repeat;
filter: none;
}
You can take advantage of such tools as the Colorzilla Gradient Editor and create your own gradient colors for all browsers and replace the original colors with your own.
And as i mentioned on the comments, i would not recommend you modifying the bootstrap.css stylesheet directly as all of your changes will be lost once the stylesheet gets updated (current version is v2.0.2) so it is preferred that you include all of your changes inside your own stylesheet, in tandem with the bootstrap.css stylesheet. But remember to overwrite all of the appropriate properties to have consistency across browsers.
Instead of trying to learn vim, use a different easier editor (like nano, for example). As much as I like vim, I do not think using it in this case is the solution. It takes dedication and time to master it.

Example to download with wget on server a big file link that can be obtained in your browser.
In example using Google Chrome.
Login where you need, and press download. Go to download and copy your link.
Then open DevTools on a page where you where login, go to Console and get your cookies, by entering document.cookie
Now, go to server and download your file: wget --header "Cookie: <YOUR_COOKIE_OUTPUT_FROM_CONSOLE>" <YOUR_DOWNLOAD_LINK>
Close NetBeans.
Stop MySQL Server.
Update MySQL (if available)
Start MySQL Server.
Open NetBeans.
If still doesn't connect, download MySQL Connector/J and add mysql-connector-java-[version].jar to your

in XAMPP is
C:\xampp\tomcat\lib.
Then repeat the steps again.
You can use the plugin ConyEdit to do this. With ConyEdit running in the background, follow these steps:
cc.spc /\t/ a
to split the text into columns and store them in a two-dim array. cc.p
to print, using the contents of the array. Note that -lm
may not always need to be specified even if you use some C math functions.
For example, the following simple program:
#include <stdio.h>
#include <math.h>
int main() {
printf("output: %f\n", sqrt(2.0));
return 0;
}
can be compiled and run successfully with the following command:
gcc test.c -o test
Tested on gcc 7.5.0 (on Ubuntu 16.04) and gcc 4.8.0 (on CentOS 7).
The post here gives some explanations:
The math functions you call are implemented by compiler built-in functions

You can not sort TreeMap on values.
A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide
comparator
forComparator<? super K>
so your comparator should compare on keys.
To provide sort on values you will need SortedSet. Use
SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Map.Entry<String, Double> e1,
Map.Entry<String, Double> e2) {
return e1.getValue().compareTo(e2.getValue());
}
});
sortedset.addAll(myMap.entrySet());
To give you an example
SortedMap<String, Double> myMap = new TreeMap<String, Double>();
myMap.put("a", 10.0);
myMap.put("b", 9.0);
myMap.put("c", 11.0);
myMap.put("d", 2.0);
sortedset.addAll(myMap.entrySet());
System.out.println(sortedset);
Output:
[d=2.0, b=9.0, a=10.0, c=11.0]
I had the problem that my new controls would not generate in the designer file when declared in the .ascx file. The problem was that i declared them in the code behind also. So deleting the declaration in the code behind solved my problem.
The line-continuation will fail if you have whitespace (spaces or tab characters[1]) after the backslash and before the newline. With no such whitespace, your example works fine for me:
$ cat test.sh
if ! fab --fabfile=.deploy/fabfile.py \
--forward-agent \
--disable-known-hosts deploy:$target; then
echo failed
else
echo succeeded
fi
$ alias fab=true; . ./test.sh
succeeded
$ alias fab=false; . ./test.sh
failed
Some detail promoted from the comments: the line-continuation backslash in the shell is not really a special case; it is simply an instance of the general rule that a backslash "quotes" the immediately-following character, preventing any special treatment it would normally be subject to. In this case, the next character is a newline, and the special treatment being prevented is terminating the command. Normally, a quoted character winds up included literally in the command; a backslashed newline is instead deleted entirely. But otherwise, the mechanism is the same. Most importantly, the backslash only quotes the immediately-following character; if that character is a space or tab, you just get a literal space or tab, and any subsequent newline remains unquoted.
[1] or carriage returns, for that matter, as Czechnology points out. Bash does not get along with Windows-formatted text files, not even in WSL. Or Cygwin, but at least their Bash port has added a set -o igncr
option that you can set to make it carriage-return-tolerant.
If the structure of your xml (or text in general) is fixed, the easiest way is using cut
. For your specific case:
echo '<table name="content_analyzer" primary-key="id">
<type="global" />
</table>
<table name="content_analyzer2" primary-key="id">
<type="global" />
</table>
<table name="content_analyzer_items" primary-key="id">
<type="global" />
</table>' | grep name= | cut -f2 -d '"'
int cores = Runtime.getRuntime().availableProcessors();
If cores
is less than one, either your processor is about to die, or your JVM has a serious bug in it, or the universe is about to blow up.
Moving any column to any position:
import pandas as pd
df = pd.DataFrame({"A": [1,2,3],
"B": [2,4,8],
"C": [5,5,5]})
cols = df.columns.tolist()
column_to_move = "C"
new_position = 1
cols.insert(new_position, cols.pop(cols.index(column_to_move)))
df = df[cols]
In my case, I fixed by the following:
* run git config --edit
* In the git config file:
[branch "master"]
remote = origin # <--- change the default origin here
I solved the problem with the following steps:
Open "services.msc" from command / Windows RUN.
Find the service (which is greyed out).
Double click on that service and go to the "Recovery" tab.
Ensure that
and Press OK.
Now, the service will not try to restart and you can able to delete the greyed out service from services list (i.e. greyed out will be gone).

Your username shouldn't be an email address, but your GitHub user account: pete
.
And your password should be your GitHub account password.
You actually can set your username directly in the remote url, in order for Git to request only your password:
cd C:\Users\petey_000\rails_projects\first_app
git remote set-url origin https://[email protected]/pete/first_app
And you need to create the fist_app
repo on GitHub first: make sure to create it completely empty, or, if you create it with an initial commit (including a README.md
, a license file and a .gitignore
file), then do a git pull first, before making your git push
.
You can try ScrollableStackView : https://github.com/gurhub/ScrollableStackView
It's Objective-C and Swift compatible library. It's available through CocoaPods.
Sample Code (Swift)

var scrollable = ScrollableStackView(frame: view.frame)
view.addSubview(scrollable)
// add your views with
let rectangle = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 55))
rectangle.backgroundColor = UIColor.blue
scrollable.stackView.addArrangedSubview(rectangle)

scrollable.stackView.distribution = UIStackViewDistributionFillProportionally;
scrollable.stackView.alignment = UIStackViewAlignmentCenter;
scrollable.stackView.axis = UILayoutConstraintAxisVertical;
[self.view addSubview:scrollable];

I solved this, without having to completely reinstall Visual Studio 2013.
For those who may come across this in the future, the following steps worked for me:
vs_professional.exe
).If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3
Click the link for 'examine the log file' and look near the bottom of the log, for this line:
open regedit.exe
and do an Edit > Find...
for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
. This was found in:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
Edit the BundleVersion
value and change it to a lower version. I changed mine from 12.0.21005.13
to 12.0.21000.13
:
Exit the registry
Run the ISO (or vs_professional.exe
) again. If it has a repair button like the image below, you can skip to step 4.
Run the ISO (or vs_professional.exe
) again. This time repair should be visible.
Click Repair
and let it update your installation and apply its embedded license key. This took about 20 minutes.
Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product
:
Hope this helps somebody in the future!
Use: xmlhttp.setRequestHeader(key, value);
The below worked for me
`enter code here`#include <stdafx.h> // Used with MS Visual Studio Express. Delete line if using something different

void WaitKey();
int main()
{
int len = 0,x, y=240; // 240 = white background, black foreground
string text = "Hello World. I feel pretty today!";
len = text.length();
cout << endl << endl << endl << "\t\t"; // start 3 down, 2 tabs, right
for ( x=0;x<len;x++)
{
SetConsoleTextAttribute(console, y); // set color for the next print
cout << text[x];
y++; // add 1 to y, for a new color
if ( y >254) // There are 255 colors. 255 being white on white. Nothing to see. Bypass it
y=240; // if y > 254, start colors back at white background, black chars
Sleep(250); // Pause between letters
}
SetConsoleTextAttribute(console, 15); // set color to black background, white chars
WaitKey(); // Program over, wait for a keypress to close program
}
void WaitKey()
{

}
Use ClassLoader#getResource()
instead if its URI represents a valid local disk file system path.
URL resource = classLoader.getResource("resource.ext");
File file = new File(resource.toURI());
FileInputStream input = new FileInputStream(file);
// ...
If it doesn't (e.g. JAR), then your best bet is to copy it into a temporary file.
Path temp = Files.createTempFile("resource-", ".ext");
Files.copy(classLoader.getResourceAsStream("resource.ext"), temp, StandardCopyOption.REPLACE_EXISTING);
FileInputStream input = new FileInputStream(temp.toFile());
// ...
That said, I really don't see any benefit of doing so, or it must be required by a poor helper class/method which requires FileInputStream
instead of InputStream
. If you can, just fix the API to ask for an InputStream
instead. If it's a 3rd party one, by all means report it as a bug. I'd in this specific case also put question marks around the remainder of that API.
The best method would be using a javascript -only function:
var myArr = Array.prototype.slice.call(myObj, 0);
The default size of the arraylist is 10. When we add the 11th ....arraylist increases the size (n*2). The values stored in old arraylist are copied into the new arraylist whose size is 20.
.reduce((o,v,i)=>(o[i]=v,o), {})
[docs]
or more verbose
var trAr2Obj = function (arr) {return arr.reduce((o,v,i)=>(o[i]=v,o), {});}
or
var transposeAr2Obj = arr=>arr.reduce((o,v,i)=>(o[i]=v,o), {})
shortest one with vanilla JS
JSON.stringify([["a", "X"], ["b", "Y"]].reduce((o,v,i)=>{return o[i]=v,o}, {}))
=> "{"0":["a","X"],"1":["b","Y"]}"
some more complex example
[["a", "X"], ["b", "Y"]].reduce((o,v,i)=>{return o[v[0]]=v.slice(1)[0],o}, {})
=> Object {a: "X", b: "Y"}
even shorter (by using function(e) {console.log(e); return e;}
=== (e)=>(console.log(e),e)
)
? nodejs
> [[1, 2, 3], [3,4,5]].reduce((o,v,i)=>(o[v[0]]=v.slice(1),o), {})
{ '1': [ 2, 3 ], '3': [ 4, 5 ] }
[/docs]
objArray.sort((a, b) => a.DepartmentName.localeCompare(b.DepartmentName))
You can also use a nested for
loop like shown below
n = 3
arr = []
for x in range(n):
arr.append([])
for y in range(n):
arr[x].append([])
for z in range(n):
arr[x][y].append(0)
print(arr)
Your question is about the operator precedences in mysql and Alex has shown you how to "override" the precedence with parentheses.
But on a side note, if your column date
is of the type Date
you can use MySQL's date and time functions to fetch the records of the last seven days, like e.g.
SELECT
*
FROM
Drinks
WHERE
email='$Email'
AND date >= Now()-Interval 7 day
(or maybe Curdate() instead of Now())
Here's a possible solution.
HTML
<img id="source" src="http://www.byui.edu/images/agriculture-life-sciences/flower.jpg" />
<div id="crop">
<img id="overlay" src="http://www.byui.edu/images/agriculture-life-sciences/flower.jpg" />
</div>
CSS
#crop {
overflow: hidden;
position: absolute;
left: 100px;
top: 100px;
width: 450px;
height: 150px;
}
#overlay {
-webkit-filter:blur(4px);
filter:blur(4px);
width: 450px;
}
#source {
height: 300px;
width: auto;
position: absolute;
left: 100px;
top: 100px;
}
I know the CSS can be simplified and you probably should get rid of the ids. The idea here is to use a div as a cropping container and then apply blur on duplicate of the image. Fiddle
To make this work in Firefox, you would have to use SVG hack.
You can either use this procedure to format your currency needing.
var nf = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',

$(document).ready(function() {
$(body).submit(function () {
var btn = $(this).find("input[type=submit]:focus");
if($(btn).prop("id") == "YourButtonID")
$(btn).attr("disabled", "true");
});
}
In the following line
<form method="post" action="display()">
the action should be the name of your script and you should call the function, Something like this
<form method="post" action="yourFileName.php">
<input type="text" name="studentname">
<input type="submit" value="click" name="submit"> <!-- assign a name for the button -->
</form>
<?php
function display()
{
echo "hello ".$_POST["studentname"];
}
if(isset($_POST['submit']))
{
display();
}
?>
To get rid of the if/else awkwardness you could use a using block:
@{
var count = 0;
foreach (var item in Model)
{
using(Html.TableRow(new { @class = (count++ % 2 == 0) ? "alt-row" : "" }))
{
<td>
@Html.DisplayFor(modelItem => item.Title)
</td>
<td>
@Html.Truncate(item.Details, 75)
</td>
<td>
<img src="@Url.Content("~/Content/Images/Projects/")@item.Images.Where(i => i.IsMain == true).Select(i => i.Name).Single()"
alt="@item.Images.Where(i => i.IsMain == true).Select(i => i.AltText).Single()" class="thumb" />
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=item.ProjectId }) |
@Html.ActionLink("Details", "Details", new { id = item.ProjectId }) |
@Html.ActionLink("Delete", "Delete", new { id=item.ProjectId })
</td>
}
}
}

The first step would be to add
position: 'absolute',
then if you want the element full width, add
left: 0,
right: 0,
then, if you want to put the element in the bottom, add
bottom: 0,
// don't need set top: 0
if you want to position the element at the top, replace bottom: 0
by top: 0

Don't use jquery...use plain javascript
var a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];
var b = a.splice(0,10);
//a is now [11,12,13,14,15];
//b is now [1,2,3,4,5,6,7,8,9,10];
You could loop this to get the behavior you want.
var a = YOUR_ARRAY;
while(a.length) {
console.log(a.splice(0,10));
}
This would give you 10 elements at a time...if you have say 15 elements, you would get 1-10, the 11-15 as you wanted.
It should be possible like this (or use jQuery like $('meta[name=author]').attr("content");
):
<html>
<head>
<title>Meta Data</title>
<meta name="Author" content="Martin Webb">
<meta name="Author" content="A.N. Other">
<meta name="Description" content="A sample html file for extracting meta data">
<meta name="Keywords" content="JavaScript, DOM, W3C">
</head>
<body>
<script language="JavaScript"><!--
if (document.getElementsByName) {
var metaArray = document.getElementsByName('Author');
for (var i=0; i<metaArray.length; i++) {
document.write(metaArray[i].content + '<br>');
}
var metaArray = document.getElementsByName('Description');
for (var i=0; i<metaArray.length; i++) {
document.write(metaArray[i].content + '<br>');
}
var metaArray = document.getElementsByName('Keywords');
for (var i=0; i<metaArray.length; i++) {
document.write(metaArray[i].content + '<br>');
}
}
//--></script>
</body>

To install font-awesome you first should install it with npm. So in your project root directory type:
npm install font-awesome --save
(Of course I assume you have node.js and npm already installed. And you've done npm install
in your projects root directory)
Then edit the resources/assets/sass/app.scss
file and add at the top this line:
@import "node_modules/font-awesome/scss/font-awesome.scss";
Now you can do for example:
npm run dev
This builds unminified versions of the resources in the correct folders. If you wanted to minify them, you would instead run:
npm run production
And then you can use the font.
Following these steps solved my problem.
node_modules
directorypackage-lock.json
filenpm install
npm run dev
This post is right from SAP on Sep 20, 2012.
In short, they are still working on a release of Crystal Reports that will support VS2012 (including support for Windows 8) It will come in the form of a service pack release that updates the version currently supporting VS2010. At that time they will drop 2010/2012 from the name and simply call it Crystal Reports Developer.
If you want to download that version you can find it here.
Further, service packs etc. when released can be found here.
I would also add that I am currently using Visual Studio 2012. As long as you don't edit existing reports they continue to compile and work fine. Even on Windows 8. When I need to modify a report I can still open the project with VS2010, do my work, save my changes, and then switch back to 2012. It's a little bit of a pain but the ability for VS2010 and VS2012 to co-exist is nice in this regard. I'm also using TFS2012 and so far it hasn't had a problem with me modifying files in 2010 on a "2012" solution.
Bhuvanesh BS solution works. Kotlin version of this:
import android.graphics.Canvas
import android.graphics.drawable.Drawable
import androidx.recyclerview.widget.RecyclerView
class DividerItemDecorator(private val mDivider: Drawable?) : RecyclerView.ItemDecoration() {
override fun onDraw(
canvas: Canvas,
parent: RecyclerView,
state: RecyclerView.State
) {
val dividerLeft = parent.paddingLeft
val dividerRight = parent.width - parent.paddingRight
for (i in 0 until parent.childCount - 1) {
val child = parent.getChildAt(i)
val dividerTop =
child.bottom + (child.layoutParams as RecyclerView.LayoutParams).bottomMargin
val dividerBottom = dividerTop + mDivider!!.intrinsicHeight
mDivider.setBounds(dividerLeft, dividerTop, dividerRight, dividerBottom)
mDivider.draw(canvas)
}
}
}
you'll need to cast it to an HtmlControl in order to access the Style property.
HtmlControl control = (HtmlControl)Page.FindControl("portlet_tab1"); control.Style.Add("display","none");
In my case I chose the Force Update
checkbox while pushing. It worked like a charm.
Use the placeholder attribute. The text disappears when the user starts typing. This is an example of a project I am working on:
<div class="" id="search-form">
<input type="text" name="" value="" class="form-control" placeholder="Search..." >
</div>
With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.
Not sure, but you should be able to do something by setting a default active profile in your settings.xml
See
See http://maven.apache.org/guides/introduction/introduction-to-profiles.html
First off, please note that I haven't used either of them (but have used Node.js).
Both libraries are documented quite well and have a stable API. However, persistence.js seems to be used in more projects. I don't know if all of them still use it, though.
The developer of sequelize sometimes blogs about it at blog.depold.com. When you'd like to use primary keys as foreign keys, you'll need the patch that's described in this blog post. If you'd like help for persistence.js there is a google group devoted to it.
From the examples I gather that sequelize is a bit more JavaScript-like (more sugar) than persistance.js but has support for fewer datastores (only MySQL, while persistance.js can even use in-browser stores).
I think that sequelize might be the way to go for you, as you only need MySQL support. However, if you need some convenient features (for instance search) or want to use a different database later on you'd need to use persistence.js.
This is an old question, but, as a newbie I figured I'd add that (using Webstorm) you need to click on Mongo Explorer (tab on far right hand side of your window). From there:
-Click settings. -Click browse button (looks like a button with "..." on it). -Go to Program Files > MongoDB > Server > 3.4 > bin > mongo.exe (your version maybe different than 3.4) -After that, click the green plus sign on the right. A window will open -Enter a name in "Label" slot. -Click apply.
You should now be connected. Entering "mongod" in the terminal isn't enough. You have to do the above steps also.
My apologies in advance to those of you who aren't using Webstorm! Not sure about the steps using other IDE's.
you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:
#!/bin/sh
OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")
if [ $? -ne 0 ]; then
echo "getopt error"
exit 1
fi
eval set -- $OPTIONS
while true; do
case "$1" in
-h|--help) HELP=1 ;;
-f|--file) FILE="$2" ; shift ;;
-g|--foo) FOO=1 ;;
-b|--bar) BAR=1 ;;
--) shift ; break ;;
*) echo "unknown option: $1" ; exit 1 ;;
esac
shift
done
if [ $# -ne 0 ]; then
echo "unknown option(s): $@"
exit 1
fi
echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"
see also:
man getopt
You could use this to wrap urllib2:
def URLRequest(url, params, method="GET"):
if method == "POST":
return urllib2.Request(url, data=urllib.urlencode(params))
else:
return urllib2.Request(url + "?" + urllib.urlencode(params))
That will return a Request object that has result data and response codes.
Ensure the OracleService is running. I keep running into this error, but when I go into Services, find OracleServiceXE and manually start it, the problem is resolved. I have it set to start automatically, but sometimes it just seems to stop on its own; at least, I can't find anything I am doing to stop it.
grep -rnw "some thing to grep" --include=*.{module,inc,php,js,css,html,htm} ./
You can just AND the results together if they are stored as TRUE / FALSE values:
=AND(A1:D2)
Or if stored as text, use an array formula - enter the below and press Ctrl+Shift+Enter instead of Enter.
=AND(EXACT(A1:D2,"TRUE"))
For anyone else running into this, I had this problem due to my npm
installing into a location that's not on my NODE_PATH
.
[root@uberneek ~]# which npm
/opt/bin/npm
[root@uberneek ~]# which node
/opt/bin/node
[root@uberneek ~]# echo $NODE_PATH
My NODE_PATH was empty, and running npm install --global --verbose promised-io
showed that it was installing into /opt/lib/node_modules/promised-io
:
[root@uberneek ~]# npm install --global --verbose promised-io
npm info it worked if it ends with ok
npm verb cli [ '/opt/bin/node',
npm verb cli '/opt/bin/npm',
npm verb cli 'install',
npm verb cli '--global',
npm verb cli '--verbose',
npm verb cli 'promised-io' ]
npm info using [email protected]
npm info using [email protected]
[cut]
npm info build /opt/lib/node_modules/promised-io
npm verb from cache /opt/lib/node_modules/promised-io/package.json
npm verb linkStuff [ true, '/opt/lib/node_modules', true, '/opt/lib/node_modules' ]
[cut]
My script fails on require('promised-io/promise')
:
[neek@uberneek project]$ node buildscripts/stringsmerge.js
module.js:340
throw err;
^
Error: Cannot find module 'promised-io/promise'
at Function.Module._resolveFilename (module.js:338:15)
I probably installed node and npm from source using configure --prefix=/opt
. I've no idea why this has made them incapable of finding installed modules. The fix for now is to point NODE_PATH at the right directory:
export NODE_PATH=/opt/lib/node_modules
My require('promised-io/promise')
now succeeds.
Run this command:
rvm get stable --auto-dotfiles
and make sure to read all the output. RVM
will tell you if something is wrong, which in your case might be because GEM_HOME
is set to something different then PATH
.
Replace double quotes with single ones:
INSERT
INTO MY.LOGFILE
(id,severity,category,logdate,appendername,message,extrainfo)
VALUES (
'dee205e29ec34',
'FATAL',
'facade.uploader.model',
'2013-06-11 17:16:31',
'LOGDB',
NULL,
NULL
)
In SQL, double quotes are used to mark identifiers, not string constants.
I had a similar challenge when writing a Powershell script to interact with AWS CLI using the AWS Powershell Tools
I ran the command:
Get-S3Bucket // List AWS S3 buckets
And then I got the error:
Get-S3Bucket : A positional parameter cannot be found that accepts argument list
Here's how I fixed it:
Get-S3Bucket
does not accept // List AWS S3 buckets
as an attribute.
I had put it there as a comment, but it's not acceptable by the AWS CLI as a comment. AWS CLI rather sees it as a parameter.
I had to do it this way:
#List AWS S3 buckets
Get-S3Bucket
That's all.
I hope this helps
you can use DateUtils class in org.apache.commons.lang3.time package
int addMinuteTime = 5;
Date targetTime = new Date(); //now
targetTime = DateUtils.addMinutes(targetTime, addMinuteTime); //add minute
See https://developer.mozilla.org/en/DOM/document.cookie for more documentation:
setItem: function (sKey, sValue, vEnd, sPath, sDomain, bSecure) {
if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/.test(sKey)) { return; }
var sExpires = "";
if (vEnd) {
switch (typeof vEnd) {
case "number": sExpires = "; max-age=" + vEnd; break;
case "string": sExpires = "; expires=" + vEnd; break;
case "object": if (vEnd.hasOwnProperty("toGMTString")) { sExpires = "; expires=" + vEnd.toGMTString(); } break;
}
}
document.cookie = escape(sKey) + "=" + escape(sValue) + sExpires + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "") + (bSecure ? "; secure" : "");
}
My favourite is to extend jQuery with this tiny convenience:
$.fn.exists = function () {
return this.length !== 0;
}
Used like:
$("#notAnElement").exists();
More explicit than using length.
You have two ways to do that:
METHOD 1. The secure way.
Put the images on /www/htdocs/
<?php
$www_root = 'http://localhost/images';
$dir = '/var/www/images';
$file_display = array('jpg', 'jpeg', 'png', 'gif');
if ( file_exists( $dir ) == false ) {
echo 'Directory \'', $dir, '\' not found!';
} else {
$dir_contents = scandir( $dir );
foreach ( $dir_contents as $file ) {
$file_type = strtolower( end( explode('.', $file ) ) );
if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
echo '<img src="', $www_root, '/', $file, '" alt="', $file, '"/>';
break;
}
}
}
?>
METHOD 2. Unsecure but more flexible.
Put the images on any directory (apache must have permission to read the file).
<?php
$dir = '/home/user/Pictures';
$file_display = array('jpg', 'jpeg', 'png', 'gif');
if ( file_exists( $dir ) == false ) {
echo 'Directory \'', $dir, '\' not found!';
} else {
$dir_contents = scandir( $dir );
foreach ( $dir_contents as $file ) {
$file_type = strtolower( end( explode('.', $file ) ) );
if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
echo '<img src="file_viewer.php?file=', base64_encode($dir . '/' . $file), '" alt="', $file, '"/>';
break;
}
}
}
?>
And create another script to read the image file.
<?php
$filename = base64_decode($_GET['file']);
// Check the folder location to avoid exploit
if (dirname($filename) == '/home/user/Pictures')
echo file_get_contents($filename);
?>
It doesn't work because name
is a reserved word in JavaScript. Change the function name to something else.
See http://www.quackit.com/javascript/javascript_reserved_words.cfm
<form id="form" onsubmit="return false;">
<input style="position:absolute; top:80%; left:5%; width:40%;" type="text" id="userInput" />
<input style="position:absolute; top:50%; left:5%; width:40%;" type="submit" onclick="othername();" />
</form>
function othername() {
var input = document.getElementById("userInput").value;
alert(input);
}
In python the with
keyword is used when working with unmanaged resources (like file streams). It is similar to the using
statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally
blocks.
From Python Docs:
The
with
statement clarifies code that previously would usetry...finally
blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.The
with
statement is a control-flow structure whose basic structure is:with expression [as variable]: with-block
The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has
__enter__()
and__exit__()
methods).
Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with
with using
.
Use the below code of a custom Toast. It may help you.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toast_layout_root"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp"
android:background="#DAAA" >
<ImageView android:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginRight="10dp" />
<TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:textColor="#FFF" />
</LinearLayout>
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.toast_layout,
(ViewGroup) findViewById(R.id.toast_layout_root));
ImageView image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.android);
TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("Hello! This is a custom toast!");
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
And check out the below links also for a custom Toast.

Suppose you have a table employee
, with the following columns:
employee (first_name, last_name, start_date)
In order to delete the rows with a duplicate first_name
column:
delete
from employee using employee,
employee e1
where employee.id > e1.id
and employee.first_name = e1.first_name
SELECT * FROM projects WHERE YEAR(Date) = 2011 AND MONTH(Date) = 5
Keep in mind if you are wanting to test this component you will want to inject the window. Use the @Inject() function to inject the window object by naming it using a string token like detailed in this duplicate
You can pipe grep
result to head
in conjunction with stdbuf.
Note, that in order to ensure stopping after Nth match, you need to using stdbuf
to make sure grep
don't buffer its output:
stdbuf -oL grep -rl 'pattern' * | head -n1
stdbuf -oL grep -o -a -m 1 -h -r "Pulsanti Operietur" /path/to/dir | head -n1
stdbuf -oL grep -nH -m 1 -R "django.conf.urls.defaults" * | head -n1
As soon as head
consumes 1 line, it terminated and grep
will receive SIGPIPE
because it still output something to pipe while head
was gone.
This assumed that no file names contain newline.
Yes it has, you can do it like this:
var str = " this is the answer "
str = str.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines)
print(srt) // "this is the answer"
CharacterSet is actually a really powerful tool to create a trim rule with much more flexibility than a pre defined set like .whitespacesAndNewlines has.
For Example:
var str = " Hello World !"
let cs = CharacterSet.init(charactersIn: " !")
str = str.trimmingCharacters(in: cs)
print(str) // "Hello World"
Here is my answer that works just fine...
You should be able to get current Activity in this way... If you structure your app with a few Activities with many fragments and you want to keep track of what is your current Activity, it would take a lot of work though. My senario was I do have one Activity with multiple Fragments. So I can keep track of Current Activity through Application Object, which can store all of the current state of Global variables.
Here is a way. When you start your Activity, you store that Activity by Application.setCurrentActivity(getIntent()); This Application will store it. On your service class, you can simply do like Intent currentIntent = Application.getCurrentActivity(); getApplication().startActivity(currentIntent);
In case you have to download a file with a size larger than the allowed memory limit (memory_limit
ini setting), which would cause the PHP Fatal error: Allowed memory size of 5242880 bytes exhausted
error, you can do this:
// File to download.
$file = '/path/to/file';
// Maximum size of chunks (in bytes).
$maxRead = 1 * 1024 * 1024; // 1MB
// Give a nice name to your download.
$fileName = 'download_file.txt';
// Open a file in read mode.
$fh = fopen($file, 'r');
// These headers will force download on browser,
// and set the custom file name for the download, respectively.
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $fileName . '"');
// Run this until we have read the whole file.
// feof (eof means "end of file") returns `true` when the handler
// has reached the end of file.
while (!feof($fh)) {
// Read and output the next chunk.
echo fread($fh, $maxRead);
// Flush the output buffer to free memory.
ob_flush();
}
// Exit to make sure not to output anything else.
exit;
Here is an example of initializing a boolean[][]:
const n = 8; // or some dynamic value
const palindrome: boolean[][] = new Array(n)
.fill(false)
.map(() => new Array(n)
.fill(false));

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 execute an .exe from a Windows service very well in Windows XP. I have done it myself in the past.
You need to make sure you had checked the option "Allow to interact with the Desktop" in the Windows service properties. If that is not done, it will not execute.
I need to check in Windows 7 or Vista as these versions requires additional security privileges so it may throw an error, but I am quite sure it can be achieved either directly or indirectly. For XP I am certain as I had done it myself.

$emit
It dispatches an event name upwards through the scope hierarchy and notify to the registered $rootScope.Scope
listeners. The event life cycle starts at the scope on which $emit
was called. The event traverses upwards toward the root scope and calls all registered listeners along the way. The event will stop propagating if one of the listeners cancels it.
$broadcast
It dispatches an event name downwards to all child scopes (and their children) and notify to the registered $rootScope.Scope
listeners. The event life cycle starts at the scope on which $broadcast
was called. All listeners for the event on this scope get notified. Afterwards, the event traverses downwards toward the child scopes and calls all registered listeners along the way. The event cannot be canceled.
$on
It listen on events of a given type. It can catch the event dispatched by $broadcast
and $emit
.

Even though a bit old thread, for those who still looking for the differences:
Aside from layout (space) taken in Hidden and not taken in Collapsed, there is another difference.
If we have custom controls inside this 'Collapsed' main control, the next time we set it to Visible, it will "load" all custom controls. It will not pre-load when window is started.
As for 'Hidden', it will load all custom controls + main control which we set as hidden when the "window" is started.
Martins answer won't work if you are instantiating the EditText programmatically. I went ahead and modified the included DigitsKeyListener
class from API 14 to allow for both comma and period as decimal separator.
To use this, call setKeyListener()
on the EditText
, e.g.
// Don't allow for signed input (minus), but allow for decimal points
editText.setKeyListener( new MyDigitsKeyListener( false, true ) );
However, you still have to use Martin's trick in the TextChangedListener
where you replace commas with periods

Speed. There is a difference between the two, but speed-wise it should be irrelevant which one you use. echo is marginally faster since it doesn't set a return value if you really want to get down to the nitty gritty.
Expression. print()
behaves like a function in that you can do:
$ret = print "Hello World"
; And $ret
will be 1
. That means that print
can be used as part of a more complex expression where echo cannot. An
example from the PHP Manual:
$b ? print "true" : print "false";
print is also part of the precedence table which it needs to be if it
is to be used within a complex expression. It is just about at the bottom
of the precedence list though. Only ,
AND
OR
XOR
are lower.
echo expression [, expression[,
expression] ... ]
But echo ( expression, expression )
is not valid.
This would be valid: echo ("howdy"),("partner")
; the same as: echo
"howdy","partner"
; (Putting the brackets in that simple example
serves
no purpose since there is no operator precedence issue with a single
term like that.)So, echo without parentheses can take multiple parameters, which get concatenated:
echo "and a ", 1, 2, 3; // comma-separated without parentheses
echo ("and a 123"); // just one parameter with parentheses
print()
can only take one parameter:
print ("and a 123");
print "and a 123";
You can use ARG variable defaultValue
and during the run command you can even update this value using --build-arg variable=value
. To use these variables in the docker file you can refer them as $variable
in run command.
Note: These variables would be available for Linux commands like RUN echo $variable
and they wouldn't persist in the image.
Have a look at the System.Diagnostics
namespace. Lots of goodies in there!
System.Diagnostics.StackTrace t = new System.Diagnostics.StackTrace();
This is really good to have a poke around in to learn whats going on under the hood.
I'd recommend that you have a look into logging solutions (Such as NLog, log4net or the Microsoft patterns and practices Enterprise Library) which may achieve your purposes and then some. Good luck mate!
A global variable has to be initialized to a constant value, like 4
or 0.0
or @"constant string"
or nil
. A object constructor, such as init
, does not return a constant value.
If you want to have a global variable, you should initialize it to nil
and then return it using a class method:
NSImage *segment = nil;
+ (NSImage *)imageSegment
{
if (segment == nil) segment = [[NSImage alloc] initWithContentsOfFile:@"/user/asd.jpg"];
return segment;
}
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 50, 200, 200)];
view.layer.backgroundColor = [UIColor whiteColor].CGColor;
view.layer.cornerRadius = 20.0;
view.layer.frame = CGRectInset(v.layer.frame, 20, 20);
view.layer.shadowOffset = CGSizeMake(1, 0);
view.layer.shadowColor = [[UIColor blackColor] CGColor];
view.layer.shadowRadius = 5;
view.layer.shadowOpacity = .25;
[self.view addSubview:view];
[view release];
If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
So this is long after the initial question, and technically it isn't a direct answer to how to use Ajax call to populate exterior variable as the question asks. However in research and responses it's been found to be extremely difficult to do this without disabling asynchronous functions within the call, or by descending into what seems like the potential for callback hell. My solution for this has been to use Axios. Using this has dramatically simplified my usages of asynchronous calls getting in the way of getting at data.
For example if I were trying to access session variables in PHP, like the User ID, via a call from JS this might be a problem. Doing something like this..
async function getSession() {
'use strict';
const getSession = await axios("http:" + url + "auth/" + "getSession");
log(getSession.data);//test
return getSession.data;
}
Which calls a PHP function that looks like this.
public function getSession() {
$session = new SessionController();
$session->Session();
$sessionObj = new \stdClass();
$sessionObj->user_id = $_SESSION["user_id"];
echo json_encode($sessionObj);
}
To invoke this using Axios do something like this.
getSession().then(function (res) {
log(res);//test
anyVariable = res;
anyFunction(res);//set any variable or populate another function waiting for the data
});
The result would be, in this case a Json object from PHP.
{"user_id":"1111111-1111-1111-1111-111111111111"}
Which you can either use in a function directly in the response section of the Axios call or set a variable or invoke another function.
Proper syntax for the Axios call would actually look like this.
getSession().then(function (res) {
log(res);//test
anyVariable = res;
anyFunction(res);//set any variable or populate another function waiting for the data
}).catch(function (error) {
console.log(error);
});
For proper error handling.
I hope this helps anyone having these issues. And yes I am aware this technically is not a direct answer to the question but given the answers supplied already I felt the need to provide this alternative solution which dramatically simplified my code on the client and server sides.
int index = dt.Rows.IndexOf(row);
But you're probably better off using a for loop instead of foreach.
public enum EnumRole {
ROLE_ANONYMOUS_USER_ROLE ("anonymous user role"),
ROLE_INTERNAL ("internal role");
private String roleName;
public String getRoleName() {
return roleName;
}
EnumRole(String roleName) {
this.roleName = roleName;
}
public static final EnumRole getByValue(String value){
return Arrays.stream(EnumRole.values()).filter(enumRole -> enumRole.roleName.equals(value)).findFirst().orElse(ROLE_ANONYMOUS_USER_ROLE);
}
public static void main(String[] args) {
System.out.println(getByValue("internal role").roleName);
}
}

No, HTML is not a programming language. The "M" stands for "Markup". Generally, a programming language allows you to describe some sort of process of doing something, whereas HTML is a way of adding context and structure to text.
If you're looking to add more alphabet soup to your CV, don't classify them at all. Just put them in a big pile called "Technologies" or whatever you like. Remember, however, that anything you list is fair game for a question.
HTML is so common that I'd expect almost any technology person to already know it (although not stuff like CSS and so on), so you might consider not listing every initialism you've ever come across. I tend to regard CVs listing too many things as suspicious, so I ask more questions to weed out the stuff that shouldn't be listed. :)
However, if your HTML experience includes serious web design stuff including Ajax, JavaScript, and so on, you might talk about those in your "Experience" section.

Great answers are:
My note here comes from what Donald Knuth once said (sorry can't find reference) that there is a construct where while-else is indistinguishable from if-else, namely (in Python):
x = 2
while x > 3:
print("foo")
break
else:
print("boo")
has the same flow (excluding low level differences) as:
x = 2
if x > 3:
print("foo")
else:
print("boo")
The point is that if-else can be considered as syntactic sugar for while-else which has implicit break
at the end of its if
block. The opposite implication, that while
loop is extension to if
, is more common (it's just repeated/looped conditional check), because if
is often taught before while
. However that isn't true because that would mean else
block in while-else would be executed each time when condition is false.
To ease your understanding think of it that way:
Without
break
,return
, etc., loop ends only when condition is no longer true and in such caseelse
block will also execute once. In case of Pythonfor
you must consider C-stylefor
loops (with conditions) or translate them towhile
.
Another note:
Premature
break
,return
, etc. inside loop makes impossible for condition to become false because execution jumped out of the loop while condition was true and it would never come back to check it again.
From the console you can try:
mysqladmin version -u USER -p PASSWD
Saved date as TEXT( 20/10/2013 03:26 ) To do query and to select records between dates?
Better version is:
SELECT TIMSTARTTIMEDATE
FROM TIMER
WHERE DATE(substr(TIMSTARTTIMEDATE,7,4)
||substr(TIMSTARTTIMEDATE,4,2)
||substr(TIMSTARTTIMEDATE,1,2))
BETWEEN DATE(20131020) AND DATE(20131021);
the substr from 20/10/2013 gives 20131020 date format DATE(20131021) - that makes SQL working with dates and using date and time functions.
OR
SELECT TIMSTARTTIMEDATE
FROM TIMER
WHERE DATE(substr(TIMSTARTTIMEDATE,7,4)
||'-'
||substr(TIMSTARTTIMEDATE,4,2)
||'-'
||substr(TIMSTARTTIMEDATE,1,2))
BETWEEN DATE('2013-10-20') AND DATE('2013-10-21');
and here is in one line
SELECT TIMSTARTTIMEDATE FROM TIMER WHERE DATE(substr(TIMSTARTTIMEDATE,7,4)||'-'||substr(TIMSTARTTIMEDATE,4,2)||'-'||substr(TIMSTARTTIMEDATE,1,2)) BETWEEN DATE('2013-10-20') AND DATE('2013-10-21');
You also need to handle exceptions from threads:
static void Main(string[] args) {
Application.ThreadException += MYThreadHandler;
}
private void MYThreadHandler(object sender, Threading.ThreadExceptionEventArgs e)
{
Console.WriteLine(e.Exception.StackTrace);
}
Whoop, sorry that was for winforms, for any threads you're using in a console application you will have to enclose in a try/catch block. Background threads that encounter unhandled exceptions do not cause the application to end.
I was also having a problem with notifications that had to emit sound, when the app was in foreground everything worked correctly, however when the app was in the background the sound just didn't come out.
The notification was sent by the server through FCM, that is, the server mounted the JSON of the notification and sent it to FCM, which then sends the notification to the apps. Even if I put the sound tag, the sound does not come out in the backgound.
Even putting the sound tag it didn't work.
After so much searching I found the solution on a github forum. I then noticed that there were two problems in my case:
1 - It was missing to send the channel_id tag, important to work in API level 26+
2 - In the Android application, for this specific case where notifications were being sent directly from the server, I had to configure the channel id in advance, so in my main Activity I had to configure the channel so that Android knew what to do when notification arrived.
In JSON sent by the server:
{
"title": string,
"body": string,
"icon": string,
"color": string,
"sound": mysound,
"channel_id": videocall,
//More stuff here ...
}
In your main Activity:
@Background
void createChannel(){
Uri sound = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.app_note_call);
NotificationChannel mChannel;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mChannel = new NotificationChannel("videocall", "VIDEO CALL", NotificationManager.IMPORTANCE_HIGH);
mChannel.setLightColor(Color.GRAY);
mChannel.enableLights(true);
mChannel.setDescription("VIDEO CALL");
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_ALARM)
.build();
mChannel.setSound(sound, audioAttributes);
NotificationManager notificationManager =
(NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.createNotificationChannel(mChannel);
}
}
This finally solved my problem, I hope it helps someone not to waste 2 days like I did. I don't know if it is necessary for everything I put in the code, but this is the way. I also didn't find the github forum link to credit the answer anymore, because what I did was the same one that was posted there.
The key here is to get the first day of the month. For that, there are several options. In terms of performance, our tests show that there isn't a significant difference between them - we wrote a whole blog article on the topic. Our findings show that what really matters is whether you need the result to be VARCHAR, DATETIME, or DATE.
The fastest solution to the real problem of getting the first day of the month returns VARCHAR:
SELECT CONCAT(LEFT(CURRENT_DATE, 7), '-01') AS first_day_of_month;
The second fastest solution gives a DATETIME result - this runs about 3x slower than the previous:
SELECT TIMESTAMP(CONCAT(LEFT(CURRENT_DATE, 7), '-01')) AS first_day_of_month;
The slowest solutions return DATE objects. Don't believe me? Run this SQL Fiddle and see for yourself
In your case, since you need to compare the value with other DATE values in your table, it doesn't really matter what methodology you use because MySQL will do the conversion implicitly even if your formula doesn't return a DATE object.
So really, take your pick. Which is most readable for you? I'd pick the first since it's the shortest and arguably the simplest:
SELECT * FROM table_name
WHERE date BETWEEN CONCAT(LEFT(CURRENT_DATE, 7), '-01') AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN DATE(CONCAT(LEFT(CURRENT_DATE, 7), '-01')) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN (LAST_DAY(CURRENT_DATE) + INTERVAL 1 DAY - INTERVAL 1 MONTH) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN (DATE(CURRENT_DATE) - INTERVAL (DAYOFMONTH(CURRENT_DATE) - 1) DAY) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN (DATE(CURRENT_DATE) - INTERVAL (DAYOFMONTH(CURRENT_DATE)) DAY + INTERVAL 1 DAY) AND CURDATE;
SELECT * FROM table_name
WHERE date BETWEEN DATE_FORMAT(CURRENT_DATE,'%Y-%m-01') AND CURDATE;
Would you be happy with your Python command running another program to get the info?
If so, I'd suggest you have a look at PsList and all its options. For example, The following would tell you about any running iTunes process
PsList itunes
If you can work out how to interpret the results, this should hopefully get you going.
Edit:
When I'm not running iTunes, I get the following:

Process information for CLARESPC:
Name Pid Pri Thd Hnd Priv CPU Time Elapsed Time
iTunesHelper 3784 8 10 229 3164 0:00:00.046 3:41:05.053
With itunes running, I get this one extra line:
iTunes 928 8 24 813 106168 0:00:08.734 0:02:08.672
However, the following command prints out info only about the iTunes program itself, i.e. with the -e
argument:
pslist -e itunes
