Going back to the Kalman Filters ... I found a C implementation for a Kalman filter for GPS data here: http://github.com/lacker/ikalman I haven't tried it out yet, but it seems promising.
Another option is to use KernelReg in statsmodels:
from statsmodels.nonparametric.kernel_regression import KernelReg
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2
# The third parameter specifies the type of the variable x;
# 'c' stands for continuous
kr = KernelReg(y,x,'c')
plt.plot(x, y, '+')
y_pred, y_std = kr.fit(x)
plt.plot(x, y_pred)
plt.show()
For this example spline works well, but if the function is not smooth inherently and you want to have smoothed version you can also try:
from scipy.ndimage.filters import gaussian_filter1d
ysmoothed = gaussian_filter1d(y, sigma=2)
plt.plot(x, ysmoothed)
plt.show()
if you increase sigma you can get a more smoothed function.
Proceed with caution with this one. It modifies the original values and may not be what you want.
If UserGroups has a one to many relationship with UserGroupPrices table, then in EF, once the relationship is defined in code like:
//In UserGroups Model
public List<UserGroupPrices> UserGrpPriceList {get;set;}
//In UserGroupPrices model
public UserGroups UserGrps {get;set;}
You can pull the left joined result set by simply this:
var list = db.UserGroupDbSet.ToList();
assuming your DbSet for the left table is UserGroupDbSet, which will include the UserGrpPriceList, which is a list of all associated records from the right table.
I've checked DamienG's answer in LinqPad. Instead of
g.Group.Max(s => s.uid)
should be
g.Max(s => s.uid)
Thank you!
UPDATE Feb. 2021
As in Activity v1.2.0 and Fragment v1.3.0, the new Activity Result APIs have been introduced.
The Activity Result APIs provide components for registering for a result, launching the result, and handling the result once it is dispatched by the system.
So there is no need of using startActivityForResult and onActivityResult anymore.
In order to use the new API, you need to create an ActivityResultLauncher in your origin Activity, specifying the callback that will be run when the destination Activity finishes and returns the desired data:
private val intentLauncher =
registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
if (result.resultCode == Activity.RESULT_OK) {
result.data?.getStringExtra("streetkey")
result.data?.getStringExtra("citykey")
result.data?.getStringExtra("homekey")
}
}
and then, launching your intent whenever you need to:
intentLauncher.launch(Intent(this, YourActivity::class.java))
And to return data from the destination Activity, you just have to add an intent with the values to return to the setResult() method:
val data = Intent()
data.putExtra("streetkey", "streetname")
data.putExtra("citykey", "cityname")
data.putExtra("homekey", "homename")
setResult(Activity.RESULT_OK, data)
finish()
For any additional information, please refer to Android Documentation
My best advice would be that there is no standard tree data structure because there are so many ways you could implement it that it would be impossible to cover all bases with one solution. The more specific a solution, the less likely it is applicable to any given problem. I even get annoyed with LinkedList - what if I want a circular linked list?
The basic structure you'll need to implement will be a collection of nodes, and here are some options to get you started. Let's assume that the class Node is the base class of the entire solution.
If you need to only navigate down the tree, then a Node class needs a List of children.
If you need to navigate up the tree, then the Node class needs a link to its parent node.
Build an AddChild method that takes care of all the minutia of these two points and any other business logic that must be implemented (child limits, sorting the children, etc.)
The calculated column trick is widely known as a "nullbuster"; my notes credit Steve Kass:
CREATE TABLE dupNulls (
pk int identity(1,1) primary key,
X int NULL,
nullbuster as (case when X is null then pk else 0 end),
CONSTRAINT dupNulls_uqX UNIQUE (X,nullbuster)
)
yes I often need to have 3 or more JVM's installed. For example, I've noticed that sometimes the JRE is slightly different to the JDK version of the JRE.
My go to solution on Windows for a bit of 'packaging' is something like this:
@echo off
setlocal
@rem _________________________
@rem
@set JAVA_HOME=b:\lang\java\jdk\v1.6\u45\x64\jre
@rem
@set JAVA_EXE=%JAVA_HOME%\bin\java
@set VER=test
@set WRK=%~d0%~p0%VER%
@rem
@pushd %WRK%
cd
@echo.
@echo %JAVA_EXE% -jar %WRK%\openmrs-standalone.jar
%JAVA_EXE% -jar %WRK%\openmrs-standalone.jar
@rem
@rem _________________________
popd
endlocal
@exit /b
I think it is straightforward. The main thing is the setlocal and endlocal give your app a "personal environment" for what ever it does -- even if there's other programs to run.
Create a Java Model using Axis wsdl2java (which can take in .xsd files).
Use a database generation tool for Java that takes in a Java Model. Surely something like Hibernate can do this? I wrote my own tool (takes a couple of days, also generates CRUD code in Java too) to save myself time at work, maybe this would be a nice personal project?
Or just do it manually so that you can check everything is correct and good! Database tools are good enough now that you can zip through creating tables for a model without too many problems.
I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.
Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.
Here is an attempt at this with your data:
import matplotlib.pyplot as plt
# ... define 2D array hist as you did
plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case
Very simply, you can rename your Python script to "pythonscript.cgi". Post that in your cgi-bin directory, add the appropriate permissions and browse to it.
This is a great link you can start with.
Hope that helps.
EDIT (09/12/2015): The second link has long been removed. Replaced it with one that provides information referenced from the original.
the values you set determine the order that your keyboard focus will move between elements on the website.
In the following example, the first time you press tab, your cursor will move to #foo, then #awesome, then #bar
<input id="foo" tabindex="1" />
<input id="bar" tabindex="3" />
<input id="awesome" tabindex="2" />
If you have not defined tab indexes anywhere, the keyboard focus will follow the HTML tags of you page in the order in which they are defined in the HTML document.
If you tab more times than you have specified tabindexes for, the focus will move as if there were no tabindexes, i.e. in the order of appearance of the HTML tags
Yes, it's called next.
for i in 0..5
if i < 2
next
end
puts "Value of local variable is #{i}"
end
This outputs the following:
Value of local variable is 2
Value of local variable is 3
Value of local variable is 4
Value of local variable is 5
=> 0..5
Use the Find method if item_manuf_id is a primary key:
var result = dtPs.Rows.Find("some value");
If you only want to know if the value is in there then use the Contains method.
if (dtPs.Rows.Contains("some value"))
{
...
}
Primary key restriction applies to Contains aswell.
As I understand, you want to recursively copy test directory into /home/server/ path...
This can be done as:
-cp -rf /home/server/folder/test/* /home/server/
Hope this helps
This is the answer you really want:
def Find(String,ToFind,Occurence = 1):
index = 0
count = 0
while index <= len(String):
try:
if String[index:index + len(ToFind)] == ToFind:
count += 1
if count == Occurence:
return index
break
index += 1
except IndexError:
return False
break
return False
For Objects try this:
function sortBy(field) {
return function(a, b) {
if (a[field] > b[field]) {
return -1;
} else if (a[field] < b[field]) {
return 1;
}
return 0;
};
}
This problem becomes apparent when you try to host a react app in github pages.
How I fixed this,
In in my main application file, called app.tsx, where I include the router.
I set the basename, eg,
<BrowserRouter basename="/Seans-TypeScript-ReactJS-Redux-Boilerplate/">
Note that it is a relative url, this completely simplifies the ability to run locally and hosted. The basename value, matches the repository title on GitHub. This is the path that GitHub pages will auto create.
That is all I needed to do.
See working example hosted on GitHub pages at
https://sean-bradley.github.io/Seans-TypeScript-ReactJS-Redux-Boilerplate/
simply
the error means that your models has changes and is not in Sync with DB ,so
go to package manager console ,
add-migration foo2
this will give a hint of what is causing the issue ,
may be you removed something or in my case I remove a data annotation .
from there you can get the change and hopefully reverse it in your model.
after that delete foo2 .
Another way in which this could be achieved is
df['color'] = df.Set.map( lambda x: 'red' if x == 'Z' else 'green')
The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix:
package main
import (
"fmt"
"time"
"strconv"
)
func main() {
i, err := strconv.ParseInt("1405544146", 10, 64)
if err != nil {
panic(err)
}
tm := time.Unix(i, 0)
fmt.Println(tm)
}
Output:
2014-07-16 20:55:46 +0000 UTC
Playground: http://play.golang.org/p/v_j6UIro7a
Edit:
Changed from strconv.Atoi to strconv.ParseInt to avoid int overflows on 32 bit systems.
I had the same error in a report query. I had columns from different tables with the same name and the prefix for each table (eg: select a.description, b.description, c.description) that runs ok in Oracle, but for the report you must have an unique alias for each column so simply add alias to the fields with the same name (select a.description a_description, b.description b_description and so on)
I actually got fed up by the lack of standard MIME sniffing methods in PHP. Install fileinfo... Use deprecated functions... Oh these work, but only for images! I got fed up of it, so I did some research and found the WHATWG Mimesniffing spec - I believe this is still a draft spec though.
Anyway, using this specification, I was able to implement a mimesniffer in PHP. Performance is not an issue. In fact on my humble machine, I was able to open and sniff thousands of files before PHP timed out.
Here is the MimeReader class.
require_once("MimeReader.php");
$mime = new MimeReader(<YOUR FILE PATH>);
$mime_type_string = $mime->getType(); // "image/jpeg" etc.
In case someone is looking for a universal event handler the following code can be used more or less (assuming that name property is set for every input):
this.handleInputChange = (e) => {
item[e.target.name] = e.target.type === "checkbox" ? e.target.checked : e.target.value;
}
For Activities shown within TabActivities use getParent()
final AlertDialog.Builder builder = new AlertDialog.Builder(getParent());
instead of
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
You want something like:
@echo off
setlocal
:PROMPT
SET /P AREYOUSURE=Are you sure (Y/[N])?
IF /I "%AREYOUSURE%" NEQ "Y" GOTO END
echo ... rest of file ...
:END
endlocal
You could also use the RANK function
=RANK(C2,$C$2:$C$7,0)
It would return data like your example:
| A | B | C
1 | name | position | points
2 | person1 | 1 | 10
3 | person2 | 2 | 9
4 | person3 | 2 | 9
5 | person4 | 2 | 9
6 | person5 | 5 | 8
7 | person6 | 6 | 7
The 'Points' column needs to be sorted into descending order.
One solution would be to auto-fill the inputs with whitespace characters, and have them clear on focus.
Example: http://nfdb.net/autofill.php
<!doctype html>
<html>
<head>
<title>Autofill Test</title>
<script>
var userfield;
// After the document has loaded, manipulate DOM elements.
window.addEventListener('load', function() {
// Get the username field element.
userfield = document.getElementById('user');
// Listen to the 'focus' event on the input element.
userfield.addEventListener('focus', function() {
// Checks if the value is the EM space character,
// and removes it when the input is recieves focus.
if (this.value == '\u2003') this.value = ''
}, false);
// Listen to the 'blur' event on the input element.
// Triggered when the user focuses on another element or window.
userfield.addEventListener('blur', function() {
// Checks if the value is empty (the user hasn't typed)
// and inserts the EM space character if necessary.
if (this.value == '') this.value = '\u2003';
}, false);
}, false);
</script>
</head>
<body>
<form method="GET" action="">
<input id="user" name="username" type="text" value=" "/><br/>
<input name="password" type="password" value=""/><br/>
<input type="submit" value="Login">
</form>
</body>
</html>
This should stop the browser from auto-filling the fields, but still allow them to auto-complete.
Here's another example that clears the form inputs after the page loads. The advantage of this method is that the inputs never have any whitespace characters in them, the disadvantage is that there's a small possibility that the auto-filled values may be visible for a few milliseconds.
<!doctype html>
<html>
<head>
<title>Autofill Test</title>
<script>
var userfield, passfield;
// Wait for the document to load, then call the clear function.
window.addEventListener('load', function() {
// Get the fields we want to clear.
userfield = document.getElementById('user');
passfield = document.getElementById('pass');
// Clear the fields.
userfield.value = '';
passfield.value = '';
// Clear the fields again after a very short period of time, in case the auto-complete is delayed.
setTimeout(function() { userfield.value = ''; passfield.value = ''; }, 50);
setTimeout(function() { userfield.value = ''; passfield.value = ''; }, 100);
}, false);
</script>
</head>
<body>
<div>This form has autofill disabled:</div>
<form name="login" method="GET" action="./autofill2.php">
<input id="user" name="username" type="text" value=""/><br/>
<input id="pass" name="password" type="password" value=""/><br/>
<input type="submit" value="Login">
</form>
<div>This form is untouched:</div>
<form name="login" method="GET" action="./autofill2.php">
<input name="username" type="text" value=""/><br/>
<input name="password" type="password" value=""/><br/>
<input type="submit" value="Login">
</form>
</body>
</html>
So it depends on how you want to pick the incrementer, but this should work:
Range("A1:" & Cells(1, i).Address).Select
Where i is the variable that represents the column you want to select (1=A, 2=B, etc.). Do you want to do this by column letter instead? We can adjust if so :)
If you want the beginning to be dynamic as well, you can try this:
Sub SelectCols()
Dim Col1 As Integer
Dim Col2 As Integer
Col1 = 2
Col2 = 4
Range(Cells(1, Col1), Cells(1, Col2)).Select
End Sub
Illegal offset type errors occur when you attempt to access an array index using an object or an array as the index key.
Example:
$x = new stdClass();
$arr = array();
echo $arr[$x];
//illegal offset type
Your $xml array contains an object or array at $xml->entry[$i]->source for some value of $i, and when you try to use that as an index key for $s, you get that warning. You'll have to make sure $xml contains what you want it to and that you're accessing it correctly.
What Oracle version are you using? Check this page which refers to Oracle 10:
http://www.acs.ilstu.edu/docs/Oracle/server.101/b10752/stats.htm
It says:
The recommended approach to gathering statistics is to allow Oracle to automatically gather the statistics. Oracle gathers statistics on all database objects automatically and maintains those statistics in a regularly-scheduled maintenance job.
I would use something similar to this:
DECLARE @DATEFROM AS DATETIME
DECLARE @DATETO AS DATETIME
DECLARE @HOLDER TABLE(DATE DATETIME)
SET @DATEFROM = '2010-08-10'
SET @DATETO = '2010-09-11'
INSERT INTO
@HOLDER
(DATE)
VALUES
(@DATEFROM)
WHILE @DATEFROM < @DATETO
BEGIN
SELECT @DATEFROM = DATEADD(D, 1, @DATEFROM)
INSERT
INTO
@HOLDER
(DATE)
VALUES
(@DATEFROM)
END
SELECT
DATE
FROM
@HOLDER
Then the @HOLDER Variable table holds all the dates incremented by day between those two dates, ready to join at your hearts content.
Value of %TEMP% environment variable is often user-specific and Windows sets it up with regard to currently logged in user account. Some user accounts may have no user profile, for example when your process runs as a service on SYSTEM, LOCALSYSTEM or other built-in account, or is invoked by IIS application with AppPool identity with Create user profile option disabled. So even when you do not overwrite %TEMP% variable explicitly, Windows may use c:\temp or even c:\windows\temp folders for, lets say, non-usual user accounts. And what's more important, process might have no access rights to this directory!
You can try lodash _.mapKeys.
var user = {_x000D_
name: "Andrew",_x000D_
id: 25,_x000D_
reported: false_x000D_
};_x000D_
_x000D_
var renamed = _.mapKeys(user, function(value, key) {_x000D_
return key + "_" + user.id;_x000D_
});_x000D_
_x000D_
console.log(renamed);<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.js"></script>A simple addClass and removeClass will do the trick on what you need..
$('#change').on('click', function() {
$('div').each(function() {
if($(this).hasClass('active')) {
$(this).removeClass('active');
} else {
$(this).addClass('active');
}
});
});

I recommend you to learn jquery first before using.
I will expand on @User's generic solution to provide a drop free alternative. This is for folks directed here based on the question's title (not OP 's problem)
Say you want to delete all rows with negative values. One liner solution is:-
df = df[(df > 0).all(axis=1)]
Step by step Explanation:--
Let's generate a 5x5 random normal distribution data frame
np.random.seed(0)
df = pd.DataFrame(np.random.randn(5,5), columns=list('ABCDE'))
A B C D E
0 1.764052 0.400157 0.978738 2.240893 1.867558
1 -0.977278 0.950088 -0.151357 -0.103219 0.410599
2 0.144044 1.454274 0.761038 0.121675 0.443863
3 0.333674 1.494079 -0.205158 0.313068 -0.854096
4 -2.552990 0.653619 0.864436 -0.742165 2.269755
Let the condition be deleting negatives. A boolean df satisfying the condition:-
df > 0
A B C D E
0 True True True True True
1 False True False False True
2 True True True True True
3 True True False True False
4 False True True False True
A boolean series for all rows satisfying the condition Note if any element in the row fails the condition the row is marked false
(df > 0).all(axis=1)
0 True
1 False
2 True
3 False
4 False
dtype: bool
Finally filter out rows from data frame based on the condition
df[(df > 0).all(axis=1)]
A B C D E
0 1.764052 0.400157 0.978738 2.240893 1.867558
2 0.144044 1.454274 0.761038 0.121675 0.443863
You can assign it back to df to actually delete vs filter ing done above
df = df[(df > 0).all(axis=1)]
This can easily be extended to filter out rows containing NaN s (non numeric entries):-
df = df[(~df.isnull()).all(axis=1)]
This can also be simplified for cases like: Delete all rows where column E is negative
df = df[(df.E>0)]
I would like to end with some profiling stats on why @User's drop solution is slower than raw column based filtration:-
%timeit df_new = df[(df.E>0)]
345 µs ± 10.5 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
%timeit dft.drop(dft[dft.E < 0].index, inplace=True)
890 µs ± 94.9 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
A column is basically a Series i.e a NumPy array, it can be indexed without any cost. For folks interested in how the underlying memory organization plays into execution speed here is a great Link on Speeding up Pandas:
If you know in advance the number of numbers to be entered (e.g. a 4-digit PIN) you could auto-dismiss after 4 key presses, as per my answer to this similar question:
No need for an additional done button in this case.
Do your groupby, and use reset_index() to make it back into a DataFrame. Then sort.
grouped = df.groupby('mygroups').sum().reset_index()
grouped.sort_values('mygroups', ascending=False)
Pass Today as value as mentioned below in $viewQuery property :
$web = Get-SPWeb "http://sitename"
$list = $web.Lists.TryGetList($listtitle)
write-host "Exporting '$($list.Title)' data from '$($web.Title)' site.."
$viewTitle = "Program Events" #Title property
#Add the column names from the ViewField property to a string collection
$viewFields = New-Object System.Collections.Specialized.StringCollection
$viewFields.Add("Event Date") > $null
$viewFields.Add("Title") > $null
#Query property
$viewQuery = "<Where><Geq><FieldRef Name='EventDate' /><Value IncludeTimeValue='TRUE' Type='DateTime'><Today/></Value></Geq></Where><OrderBy><FieldRef Name='EventDate' Ascending='True' /></OrderBy>"
#RowLimit property
$viewRowLimit = 30
#Paged property
$viewPaged = $true
#DefaultView property
$viewDefaultView = $false
#Create the view in the destination list
$newview = $list.Views.Add($viewTitle, $viewFields, $viewQuery, $viewRowLimit, $viewPaged, $viewDefaultView)
Write-Host ("View '" + $newview.Title + "' created in list '" + $list.Title + "' on site " + $web.Url)
$web.Dispose()
We are also getting the same error while we are trying to access a same resource with in milliseconds. Like if i try to POST some data to www.abc.com/blog and with in milliseconds an other request will also go for the same resource i.e. www.abc.com/blog from the same user. So it'll give the 409 error.
I am not convinced to expose security/config keys to client. I would not call it secure, not because some one can steal all private information from first day, because someone can make excessive request, and drain your quota and make you owe to Google a lot of money.
You need to think about many concepts from restricting people not to access where they are not supposed to be, DOS attacks etc.
I would more prefer the client first will hit to your web server, there you put what ever first hand firewall, captcha , cloudflare, custom security in between the client and server, or between server and firebase and you are good to go. At least you can first stop suspect activity before it reaches to firebase. You will have much more flexibility.
I only see one good usage scenario for using client based config for internal usages. For example, you have internal domain, and you are pretty sure outsiders cannot access there, so you can setup environment like browser -> firebase type.
But still, the memory address for each letter in this address is different.
Memory address is different but as its array of characters they are sequential. When you pass address of first element and use %s, printf will print all characters starting from given address until it finds '\0'.
Log in :URL = "localhost:8080/" Enter username and pass word Click Manager App Scroll Down and find "WAR file to deploy" Chose file and click deploy
Done
Go to Webapp folder of you Apache tomcat you will see a folder name matching with your war file name.
Type link in your url address bar:: localhost:8080/HelloWorld/HelloWorld.html and press enter
Done
Instead of altering the original bootstrap css class create a new css file that will override the default style.
Make sure you include the new css file after including the bootstrap.css file.
In the new css file do
.form-horizontal .control-label{
text-align:left !important;
}
I'm pretty sure this is a bug in Chrome. Most likely it happens if you resize the browser TO full screen, then switch tabs. And sometimes if you just switch tabs/open a new one. Good to hear you found a "fix" though.
This works for me
const Generic = <T> (value: T) => {
return value;
}
Their are a few differences.
#define HELLO "Hello World"
The statement above can be used with preprocessor and can only be change in the preprocessor.
const char *HELLO2 = "Howdy";
The statement above can be changed with c code. Now you can't change the each individual character around like the statement below because its constant.
HELLO2[0] = 'a'
But you what you can do is have it point to a different string like the statement below
HELLO2 = "HELLO WOLRD"
It really depends on how you want to be able to change the variable around. With the preprocessor or c code.
If you want to do this in code, here is a sample:
pd = new ProgressDialog(MainActivity.this);
pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
pd.getWindow().setGravity(Gravity.CENTER_HORIZONTAL|Gravity.CENTER_VERTICAL);
TextView tv = new TextView(this);
tv.setTextColor(Color.WHITE);
tv.setTextSize(20);
tv.setText("Waiting...");
pd.setCustomTitle(tv);
pd.setIndeterminate(true);
pd.show();
Using TextView gives you an option to change color, size, and font of your text. Otherwise you can just call setMessage(), as usual.
My dirty solution:
private static Bitmap getDropShadow3(Bitmap bitmap) {
if (bitmap==null) return null;
int think = 6;
int w = bitmap.getWidth();
int h = bitmap.getHeight();
int newW = w - (think);
int newH = h - (think);
Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(w, h, conf);
Bitmap sbmp = Bitmap.createScaledBitmap(bitmap, newW, newH, false);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
Canvas c = new Canvas(bmp);
// Right
Shader rshader = new LinearGradient(newW, 0, w, 0, Color.GRAY, Color.LTGRAY, Shader.TileMode.CLAMP);
paint.setShader(rshader);

An alternative way is to install the Maven for Java plugin and create a maven project within Visual Studio. The steps are described in the official documentation:
This error means that, while linking, compiler is not able to find the definition of main() function anywhere.
In your makefile, the main rule will expand to something like this.
main: producer.o consumer.o AddRemove.o
gcc -pthread -Wall -o producer.o consumer.o AddRemove.o
As per the gcc manual page, the use of -o switch is as below
-o file Place output in file file. This applies regardless to whatever sort of output is being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code. If
-ois not specified, the default is to put an executable file ina.out.
It means, gcc will put the output in the filename provided immediate next to -o switch. So, here instead of linking all the .o files together and creating the binary [main, in your case], its creating the binary as producer.o, linking the other .o files. Please correct that.
Old post, but I just ran into a very similar problem. After some experimenting, I found that you can do this with a single command:
kill $(ps aux | grep <process_name> | grep -v "grep" | cut -d " " -f2)
In OP's case, <process_name> would be "gedit file.txt".
Another solution using essentially a dilate operator:
import numpy as np
from scipy.ndimage import rank_filter
def find_local_maxima(x):
x_dilate = rank_filter(x, -1, size=3)
return x_dilate == x
and for the minima:
def find_local_minima(x):
x_erode = rank_filter(x, -0, size=3)
return x_erode == x
Also, from scipy.ndimage you can replace rank_filter(x, -1, size=3) with grey_dilation and rank_filter(x, 0, size=3) with grey_erosion. This won't require a local sort, so it is slightly faster.
This can be done using Mongo's db.copyDatabase method:
db.copyDatabase(fromdb, todb, fromhost, username, password)
Reference: http://docs.mongodb.org/manual/reference/method/db.copyDatabase/
Modifying, or more correctly, adding additional HTTP headers is a great code debugging tool if nothing else.
When a URL request returns a redirect or an image there is no html "page" to temporarily write the results of debug code to - at least not one that is visible in a browser.
One approach is to write the data to a local log file and view that file later. Another is to temporarily add HTTP headers reflecting the data and variables being debugged.
I regularly add extra HTTP headers like X-fubar-somevar: or X-testing-someresult: to test things out - and have found a lot of bugs that would have otherwise been very difficult to trace.
Using regex:
if re.match(r'^\s*$', line):
# line is empty (has only the following: \t\n\r and whitespace)
Using regex + filter():
filtered = filter(lambda x: not re.match(r'^\s*$', x), original)
As seen on codepad.
A logging script that I have written some time ago might be of help, although it is not exactly what you want. It acts in a way like a System.out.println but with much more information about StackTrace etc. It also provides Clickable text for Eclipse:
private static final SimpleDateFormat extended = new SimpleDateFormat( "dd MMM yyyy (HH:mm:ss) zz" );
public static java.util.logging.Logger initLogger(final String name) {
final java.util.logging.Logger logger = java.util.logging.Logger.getLogger( name );
try {
Handler ch = new ConsoleHandler();
logger.addHandler( ch );
logger.setLevel( Level.ALL ); // Level selbst setzen
logger.setUseParentHandlers( false );
final java.util.logging.SimpleFormatter formatter = new SimpleFormatter() {
@Override
public synchronized String format(final LogRecord record) {
StackTraceElement[] trace = new Throwable().getStackTrace();
String clickable = "(" + trace[ 7 ].getFileName() + ":" + trace[ 7 ].getLineNumber() + ") ";
/* Clickable text in Console. */
for( int i = 8; i < trace.length; i++ ) {
/* 0 - 6 is the logging trace, 7 - x is the trace until log method was called */
if( trace[ i ].getFileName() == null )
continue;
clickable = "(" + trace[ i ].getFileName() + ":" + trace[ i ].getLineNumber() + ") -> " + clickable;
}
final String time = "<" + extended.format( new Date( record.getMillis() ) ) + "> ";
StringBuilder level = new StringBuilder("[" + record.getLevel() + "] ");
while( level.length() < 15 ) /* extend for tabby display */
level.append(" ");
StringBuilder name = new StringBuilder(record.getLoggerName()).append(": ");
while( name.length() < 15 ) /* extend for tabby display */
name.append(" ");
String thread = Thread.currentThread().getName();
if( thread.length() > 18 ) /* trim if too long */
thread = thread.substring( 0, 16 ) + "...";
else {
StringBuilder sb = new StringBuilder(thread);
while( sb.length() < 18 ) /* extend for tabby display */
sb.append(" ");
thread = sb.insert( 0, "Thread " ).toString();
}
final String message = "\"" + record.getMessage() + "\" ";
return level + time + thread + name + clickable + message + "\n";
}
};
ch.setFormatter( formatter );
ch.setLevel( Level.ALL );
} catch( final SecurityException e ) {
e.printStackTrace();
}
return logger;
}
Notice this outputs to the console, you can change that, see http://docs.oracle.com/javase/1.4.2/docs/api/java/util/logging/Logger.html for more information on that.
Now, the following will probably do what you want. It will go through all causes of a Throwable and save it in a String. Note that this does not use StringBuilder, so you can optimize by changing it.
Throwable e = ...
String detail = e.getClass().getName() + ": " + e.getMessage();
for( final StackTraceElement s : e.getStackTrace() )
detail += "\n\t" + s.toString();
while( ( e = e.getCause() ) != null ) {
detail += "\nCaused by: ";
for( final StackTraceElement s : e.getStackTrace() )
detail += "\n\t" + s.toString();
}

You need to make the object first, then use [] to set it.
var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);
UPDATE 2018:
If you're able to use ES6 and Babel, you can use this new feature:
{
[yourKeyVariable]: someValueArray,
}
Aside from pandas, Apache pyarrow also provides way to transform parquet to dataframe
The code is simple, just type:
import pyarrow.parquet as pq
df = pq.read_table(source=your_file_path).to_pandas()
For more information, see the document from Apache pyarrow Reading and Writing Single Files
Iterator is super class of ListIterator.
Here are the differences between them:
iterator you can move only forward, but with ListIterator you can move backword also while reading the elements.ListIterator you can obtain the index at any point while traversing, which is not possible with iterators.iterator you can check only for next element available or not, but in listiterator you can check previous and next elements.listiterator you can add new element at any point of time, while traversing. Not possible with iterator.listiterator you can modify an element while traversing, which is not possible with iterator.Iterator look and feel:
public interface Iterator<E> {
boolean hasNext();
E next();
void remove(); //optional-->use only once with next(),
dont use it when u use for:each
}
ListIterator look and feel:
public interface ListIterator<E> extends Iterator<E> {
boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove(); //optional
void set(E e); //optional
void add(E e); //optional
}
I was struggling with this exact issue for three days. I had set permissions on the script to 755. I had been calling my script as follows.
<?php
$outcome = shell_exec('/tmp/clearUp.sh');
echo $outcome;
?>
My script was as follows.
#!bin/bash
find . -maxdepth 1 -name "search*.csv" -mmin +0 -exec rm {} \;
I was getting no output or feedback. The change I made to get the script to run was to add a cd to tmp inside the script:
#!bin/bash
cd /tmp;
find . -maxdepth 1 -name "search*.csv" -mmin +0 -exec rm {} \;
This was more by luck than judgement but it is now working perfectly. I hope this helps.
Two variants on what's already been given:
git archive --format=tar --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | tar -O -xf -
and:
git archive --format=zip --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | funzip
These write the file to standard output.
This expands on the answer by Denis Bubnov.
I used this to find child values of array elements—namely if there was a anchor field in paragraphs on a Drupal 8 site to build a table of contents.
{% set count = 0 %}
{% for anchor in items %}
{% if anchor.content['#paragraph'].field_anchor_link.0.value %}
{% set count = count + 1 %}
{% endif %}
{% endfor %}
{% if count > 0 %}
--- build the toc here --
{% endif %}
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.
Not sure if the most efficient way, but this worked for me:
from pyspark.sql.functions import col
df1.alias('a').join(df2.alias('b'),col('b.id') == col('a.id')).select([col('a.'+xx) for xx in a.columns] + [col('b.other1'),col('b.other2')])
The trick is in:
[col('a.'+xx) for xx in a.columns] : all columns in a
[col('b.other1'),col('b.other2')] : some columns of b
The font may exist with different names, and not at all on some systems, so you need to use different variations and fallback to get the closest possible look on all systems:
font-family: "Comic Sans MS", "Comic Sans", cursive;
Be careful what you use this font for, though. Many consider it as ugly and overused, so it should not be use for something that should look professional.
// Safari uses pre-calculated pixels, so use this feature to detect Safari
var canva = document.createElement('canvas');
var ctx = canva.getContext("2d");
var img = ctx.getImageData(0, 0, 1, 1);
var pix = img.data; // byte array, rgba
var isSafari = (pix[3] != 0); // alpha in Safari is not zero
Use upper-case HH for 24h format:
String s = curr.ToString("HH:mm");
You get a fully functional binary without sources.
Native modules also supported. (must be placed in the same folder)
JavaScript code is transformed into native code at compile-time using V8 internal compiler. Hence, your sources are not required to execute the binary, and they are not packaged.
Perfectly optimized native code can be generated only at run-time based on the client's machine. Without that info EncloseJS can generate only "unoptimized" code. It runs about 2x slower than NodeJS.
Also, node.js runtime code is put inside the executable (along with your code) to support node API for your application at run-time.
Use cases:
This worked for me and also worked with bootstrap tables
<style>
.table td, .table th {
font-size: 10px;
}
</style>
try {
File img = new File("somefile.png");
BufferedImage image = ImageIO.read(img );
System.out.println(image);
} catch (IOException e) {
e.printStackTrace();
}
Example output for my image file:
BufferedImage@5d391d: type = 5 ColorModel: #pixelBits = 24
numComponents = 3 color
space = java.awt.color.ICC_ColorSpace@50a649
transparency = 1
has alpha = false
isAlphaPre = false
ByteInterleavedRaster:
width = 800
height = 600
#numDataElements 3
dataOff[0] = 2
You can run System.out.println(object); on just about any object and get some information about it.
The answers by Bomber and Jakub (Thanks!) are correct and work for me in different situations.
For a quick glance at what was in the commit, I use
git show <replace this with your commit-id>
But I like to view a graphical Diff when studying something in detail and have set up a P4diff as my git diff and then use
git diff <replace this with your commit-id>^!
You mean the tellItLikeItIs method? Yes, you have to specify void to specify that the method doesn't return anything. All methods have to have a return type specified, even if it's void.
It certainly doesn't return a string - look, there are no return statements anywhere. It's not really clear why you think it is returning a string. It's printing strings to the console, but that's not the same thing as returning one from the method.
There is a middle way. If you want a HTML control but you need to access it server side you can simply add the runat="server" attribute:
<a runat="server" Id="lnkBack">Back</a>
You can then alter the href server side using Attributes
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
lnkBack.Attributes.Add("href", url);
}
}
resulting in:
<a id="ctl00_ctl00_mainContentPlaceHolder_contentPlaceHolder_lnkBack"
href="url.aspx">Back</a>
Are you specifically trying to rotate the links only? Because doing it on the LI tags seems to work fine.
According to Snook transforms require the elements affected be block. He's also got some code there to make this work for IE using filters, if you care to add it on(though there appears to be some limitation on values).
I really liked this answer by superluminary and especially the way he wrapped is solution in a jQuery plugin. So thanks to superluminary for a very useful answer. In my case, though, I wanted a plugin that would allow me to define the success and error event handlers by means of options when the plugin is initialized.
So here is what I came up with:
;(function(defaults, $, undefined) {
var getSubmitHandler = function(onsubmit, success, error) {
return function(event) {
if (typeof onsubmit === 'function') {
onsubmit.call(this, event);
}
var form = $(this);
$.ajax({
type: form.attr('method'),
url: form.attr('action'),
data: form.serialize()
}).done(function() {
if (typeof success === 'function') {
success.apply(this, arguments);
}
}).fail(function() {
if (typeof error === 'function') {
error.apply(this, arguments);
}
});
event.preventDefault();
};
};
$.fn.extend({
// Usage:
// jQuery(selector).ajaxForm({
// onsubmit:function() {},
// success:function() {},
// error: function() {}
// });
ajaxForm : function(options) {
options = $.extend({}, defaults, options);
return $(this).each(function() {
$(this).submit(getSubmitHandler(options['onsubmit'], options['success'], options['error']));
});
}
});
})({}, jQuery);
This plugin allows me to very easily "ajaxify" html forms on the page and provide onsubmit, success and error event handlers for implementing feedback to the user of the status of the form submit. This allowed the plugin to be used as follows:
$('form').ajaxForm({
onsubmit: function(event) {
// User submitted the form
},
success: function(data, textStatus, jqXHR) {
// The form was successfully submitted
},
error: function(jqXHR, textStatus, errorThrown) {
// The submit action failed
}
});
Note that the success and error event handlers receive the same arguments that you would receive from the corresponding events of the jQuery ajax method.
Looks like you are doing a Python implementation of the Coursera Machine Learning Neural Network exercise. Here's what I did for randInitializeWeights(L_in, L_out)
#get a random array of floats between 0 and 1 as Pavel mentioned
W = numpy.random.random((L_out, L_in +1))
#normalize so that it spans a range of twice epsilon
W = W * 2 * epsilon
#shift so that mean is at zero
W = W - epsilon
Once you have your PropertyInfo (from GetProperty), you need to call GetValue and pass in the instance that you want to get the value from. In your case:
d.GetType().GetProperty("value2").GetValue(d, null);
ORA-12560: TNS:erro de adaptador de protocolo
You have to chose 'Fill' in the Dock property.
The file can be loaded and used like this:
#!/usr/bin/env python
import ConfigParser
import io
# Load the configuration file
with open("config.yml") as f:
sample_config = f.read()
config = ConfigParser.RawConfigParser(allow_no_value=True)
config.readfp(io.BytesIO(sample_config))
# List all contents
print("List all contents")
for section in config.sections():
print("Section: %s" % section)
for options in config.options(section):
print("x %s:::%s:::%s" % (options,
config.get(section, options),
str(type(options))))
# Print some contents
print("\nPrint some contents")
print(config.get('other', 'use_anonymous')) # Just get the value
print(config.getboolean('other', 'use_anonymous')) # You know the datatype?
which outputs
List all contents
Section: mysql
x host:::localhost:::<type 'str'>
x user:::root:::<type 'str'>
x passwd:::my secret password:::<type 'str'>
x db:::write-math:::<type 'str'>
Section: other
x preprocessing_queue:::["preprocessing.scale_and_center",
"preprocessing.dot_reduction",
"preprocessing.connect_lines"]:::<type 'str'>
x use_anonymous:::yes:::<type 'str'>
Print some contents
yes
True
As you can see, you can use a standard data format that is easy to read and write. Methods like getboolean and getint allow you to get the datatype instead of a simple string.
Writing configuration
import os
configfile_name = "config.yaml"
# Check if there is already a configurtion file
if not os.path.isfile(configfile_name):
# Create the configuration file as it doesn't exist yet
cfgfile = open(configfile_name, 'w')
# Add content to the file
Config = ConfigParser.ConfigParser()
Config.add_section('mysql')
Config.set('mysql', 'host', 'localhost')
Config.set('mysql', 'user', 'root')
Config.set('mysql', 'passwd', 'my secret password')
Config.set('mysql', 'db', 'write-math')
Config.add_section('other')
Config.set('other',
'preprocessing_queue',
['preprocessing.scale_and_center',
'preprocessing.dot_reduction',
'preprocessing.connect_lines'])
Config.set('other', 'use_anonymous', True)
Config.write(cfgfile)
cfgfile.close()
results in
[mysql]
host = localhost
user = root
passwd = my secret password
db = write-math
[other]
preprocessing_queue = ['preprocessing.scale_and_center', 'preprocessing.dot_reduction', 'preprocessing.connect_lines']
use_anonymous = True
Seems not to be used at all for configuration files by the Python community. However, parsing / writing XML is easy and there are plenty of possibilities to do so with Python. One is BeautifulSoup:
from BeautifulSoup import BeautifulSoup
with open("config.xml") as f:
content = f.read()
y = BeautifulSoup(content)
print(y.mysql.host.contents[0])
for tag in y.other.preprocessing_queue:
print(tag)
where the config.xml might look like this
<config>
<mysql>
<host>localhost</host>
<user>root</user>
<passwd>my secret password</passwd>
<db>write-math</db>
</mysql>
<other>
<preprocessing_queue>
<li>preprocessing.scale_and_center</li>
<li>preprocessing.dot_reduction</li>
<li>preprocessing.connect_lines</li>
</preprocessing_queue>
<use_anonymous value="true" />
</other>
</config>
The spec is the place to go for full answers to these questions. Here's a summary:
x, you can:null by direct comparison using ===. Example: x === nullundefined by either of two basic methods: direct comparison with undefined or typeof. For various reasons, I prefer typeof x === "undefined".null and undefined by using == and relying on the slightly arcane type coercion rules that mean x == null does exactly what you want.== and === is that if the operands are of different types, === will always return false while == will convert one or both operands into the same type using rules that lead to some slightly unintuitive behaviour. If the operands are of the same type (e.g. both are strings, such as in the typeof comparison above), == and === will behave exactly the same.More reading:
As an alternative, if there's not a specific reason to use Math.random(), use Random.nextInt():
import java.util.Random;
Random rnd = new Random();
int abc = rnd.nextInt(100); // +1 if you want 1-100, otherwise will be 0-99.

First make your template into a jQuery object:
var template = $("<li><div class='bar'>bla</div></li>");
Then set the attributes and append it to the DOM.
template.find('li').attr('id','1234');
$(document.body).append(template);
Note that it however makes no sense at all to add a li directly to the DOM since li should always be children of ul or ol. Also it is better to not make jQuery parse raw HTML. Instead create a li, set its attributes. Create a div and set it's attributes. Insert the div into the li and then append the li to the DOM.
Reference array:
var array = [
{ ID: '100', },
{ ID: '200', },
{ ID: '300', },
{ ID: '400', },
{ ID: '500', }
];
Using filter and indexOf:
var in_array = array.filter(function(item) {
return item.ID == '200' // look for the item where ID is equal to value
});
var index = array.indexOf(in_array[0]);
Looping through each item in the array using indexOf:
for (var i = 0; i < array.length; i++) {
var item= array[i];
if (item.ID == '200') {
var index = array.indexOf(item);
}
}
If you want to discard the array at the same time as summing, you could do (say, stack is the array):
var stack = [1,2,3],
sum = 0;
while(stack.length > 0) { sum += stack.pop() };
You should always use .equals() when comparing Strings in Java.
JUnit calls the .equals() method to determine equality in the method assertEquals(Object o1, Object o2).
So, you are definitely safe using assertEquals(string1, string2). (Because Strings are Objects)
Here is a link to a great Stackoverflow question regarding some of the differences between == and .equals().
Enable Multidex through build.gradle of your app module

In my case my object also had property which was array of files. Since they are binary they should be dealt differently - index doesn't need to be part of the key. So i modified @Vladimir Novopashin's and @developer033's answer:
export function convertToFormData(data, formData, parentKey) {
if(data === null || data === undefined) return null;
formData = formData || new FormData();
if (typeof data === 'object' && !(data instanceof Date) && !(data instanceof File)) {
Object.keys(data).forEach(key =>
convertToFormData(data[key], formData, (!parentKey ? key : (data[key] instanceof File ? parentKey : `${parentKey}[${key}]`)))
);
} else {
formData.append(parentKey, data);
}
return formData;
}

Looks like when upgrading to OS X El Capitain, the /usr/local directory is modified in multiple ways :
[Edit] There's also a preliminary thing to do : upgrade Xcode...
$ sudo chown -R $(whoami):admin /usr/local
This will fix permissions on the /usr/local directory which will then help both gem install and brew install|link|... commands working properly.
Make sure you have fixed the permissions of the /usr/local directory (see #1 above)
First try to reinstall your gem using :
sudo gem install <gemname>
Note that it will install the latest version of the specified gem.
If you don't want to face backward-compatibility issues, I suggest that you first determine which version of which gem you want to get and then reinstall it with the -v version. See an exemple below to make sure that the system won't get a new version of capistrano.
$ gem list | grep capistrano
capistrano (3.4.0, 3.2.1, 2.14.2)
$ sudo gem install capistrano -v 3.4.0
Update brew and upgrade your formulas
$ brew update
$ brew upgrade
You might also need to re-link some of them manually
$ brew link <formula>
Sometimes it's better to think like a parser, like T-SQL parser. While executing the statement, parser does not have any value in Pivot section and you can't have any check expression in that section. By the way, you can simply use this:
SELECT CLASS
, IsNull([AZ], 0)
, IsNull([CA], 0)
, IsNull([TX], 0)
FROM #TEMP
PIVOT (
SUM(DATA)
FOR STATE IN (
[AZ]
, [CA]
, [TX]
)
) AS PVT
ORDER BY CLASS
Arrays are not very dynamic in VBScript. You'll have to use the ReDim Preserve statement to grow the existing array so it can accommodate an extra item:
ReDim Preserve yourArray(UBound(yourArray) + 1)
yourArray(UBound(yourArray)) = "Watermelons"
With Java 8 we get a new Date / Time API (JSR 310).
The following way can be used to parse the date in Java 8 without relying on Joda-Time:
String str = "January 2nd, 2010";
// if we 2nd even we have changed in pattern also it is not working please workout with 2nd
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMMM Q, yyyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse(str, formatter);
// access date fields
int year = date.getYear(); // 2010
int day = date.getDayOfMonth(); // 2
Month month = date.getMonth(); // JANUARY
int monthAsInt = month.getValue(); // 1
LocalDate is the standard Java 8 class for representing a date (without time). If you want to parse values that contain date and time information you should use LocalDateTime. For values with timezones use ZonedDateTime. Both provide a parse() method similar to LocalDate:
LocalDateTime dateWithTime = LocalDateTime.parse(strWithDateAndTime, dateTimeFormatter);
ZonedDateTime zoned = ZonedDateTime.parse(strWithTimeZone, zoneFormatter);
The list formatting characters from DateTimeFormatter Javadoc:
All letters 'A' to 'Z' and 'a' to 'z' are reserved as pattern letters.
The following pattern letters are defined:

A clone is simply a copy of a repository. On the surface, its result is equivalent to svn checkout, where you download source code from some other repository. The difference between centralized VCS like Subversion and DVCSs like Git is that in Git, when you clone, you are actually copying the entire source repository, including all the history and branches. You now have a new repository on your machine and any commits you make go into that repository. Nobody will see any changes until you push those commits to another repository (or the original one) or until someone pulls commits from your repository, if it is publicly accessible.
A branch is something that is within a repository. Conceptually, it represents a thread of development. You usually have a master branch, but you may also have a branch where you are working on some feature xyz, and another one to fix bug abc. When you have checked out a branch, any commits you make will stay on that branch and not be shared with other branches until you merge them with or rebase them onto the branch in question. Of course, Git seems a little weird when it comes to branches until you look at the underlying model of how branches are implemented. Rather than explain it myself (I've already said too much, methinks), I'll link to the "computer science" explanation of how Git models branches and commits, taken from the Git website:
http://eagain.net/articles/git-for-computer-scientists/
A fork isn't a Git concept really, it's more a political/social idea. That is, if some people aren't happy with the way a project is going, they can take the source code and work on it themselves separate from the original developers. That would be considered a fork. Git makes forking easy because everyone already has their own "master" copy of the source code, so it's as simple as cutting ties with the original project developers and doesn't require exporting history from a shared repository like you might have to do with SVN.
EDIT: since I was not aware of the modern definition of "fork" as used by sites such as GitHub, please take a look at the comments and also Michael Durrant's answer below mine for more information.

Note: This assumes that you will declare constants for row and column indexes named COLUMN_HEADING_ROW, FIRST_COL, and LAST_COL, and that _xlSheet is the name of the ExcelSheet (using Microsoft.Interop.Excel)
First, define the range:
var columnHeadingsRange = _xlSheet.Range[
_xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
_xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];
Then, set the background color of that range:
columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;
Finally, set the font color:
columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;
And here's the code combined:
var columnHeadingsRange = _xlSheet.Range[
_xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
_xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];
columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;
columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;
The Python executable might be installed at a location other than /usr/bin, but env is nearly always present in that location so using /usr/bin/envis more portable.
You would need to restart the Postgresql Server.
If you are using ubuntu you can restart Postgresql by following command

I second Blindy's suggestion to use the MAC address of the (first?) network adapter. Yes, the MAC address can be spoofed, but this has side effects (you don't want two PCs with the same MAC address in the same network), and it's something that "your average pirate" won't do just to be able to use your software. Considering that there's no 100% solution against software piracy, the MAC address is a good compromise, IMO.
Note, however, that the address will change when the user adds, replaces or removes a network card (or replaces his old PC altogether), so be prepared to help your customers and give them a new key when they change their hardware configuration.

Newer version:
GlideApp.with(imageView)
.asBitmap()
.override(200, 200)
.centerCrop()
.load(mUrl)
.error(R.drawable.defaultavatar)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.signature(ObjectKey(System.currentTimeMillis() / (1000*60*60*24))) //refresh avatar cache every day
.into(object : CustomTarget<Bitmap>(){
override fun onLoadCleared(placeholder: Drawable?) {}
override fun onLoadFailed(errorDrawable: Drawable?) {
//add context null check in case the user left the fragment when the callback returns
context?.let { imageView.addImage(BitmapFactory.decodeResource(resources, R.drawable.defaultavatar)) }
}
override fun onResourceReady(
resource: Bitmap,
transition: Transition<in Bitmap>?) { context?.let { imageView.addImage(resource) } }
})
Another replacement would be dotPeek. JetBrains announced it as a free tool. It will probably have more features when used with their Resharper but even when used alone it works very well.
User experience is more like MSVS than a standalone disassembler. I like code reading more than in Reflector. Ctrl+T navigation suits me better too. Just synchronizing the tree with the code pane could be better.
All in all, it is still in development but very well usable already.
This is a long way round, but if you have not yet implemented then you can originally create your models this way. The method below describes altering an existing database.
1) Create a new model for the email providers:
$ rails g model provider name
2) This will create your model with a name string and timestamps. It also creates the migration which we need to add to the schema with:
$ rake db:migrate
3) Add a migration to add the providers ID into the Contact:
$ rails g migration AddProviderRefToContacts provider:references
4) Go over the migration file to check it look OK, and migrate that too:
$ rake db:migrate
5) Okay, now we have a provider_id, we no longer need the original email_provider string:
$ rails g migration RemoveEmailProviderFromContacts
6) Inside the migration file, add the change which will look something like:
class RemoveEmailProviderFromContacts < ActiveRecord::Migration
def change
remove_column :contacts, :email_provider
end
end
7) Once that is done, migrate the change:
$ rake db:migrate
8) Let's take this moment to update our models:
Contact: belongs_to :provider
Provider: has_many :contacts
9) Then, we set up the drop down logic in the _form.html.erb partial in the views:
<div class="field">
<%= f.label :provider %><br>
<%= f.collection_select :provider_id, Provider.all, :id, :name %>
</div>
10) Finally, we need to add the provders themselves. One way top do that would be to use the seed file:
Provider.destroy_all
gmail = Provider.create!(name: "gmail")
yahoo = Provider.create!(name: "yahoo")
msn = Provider.create!(name: "msn")
$ rake db:seed
As a bonus, I'd like to offer kind of a different solution to your issue. You seem to be dealing with nested dictionaries, which is usually tedious, especially when you have to check for existence of an inner key.
There are some interesting libraries regarding this on pypi, here is a quick search for you.
In your specific case, dict_digger seems suited.
>>> import dict_digger
>>> d = {
'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
'Grapes':{'Arabian':'25','Indian':'20'}
}
>>> print(dict_digger.dig(d, 'Apple','American'))
16
>>> print(dict_digger.dig(d, 'Grapes','American'))
None
@Table's name attribute is the actual table name. @Entitiy's name is useful if you have two @Entity classes with the same name and you need a way to differentiate them when running queries.
Although this post is 6 years old now, however, a lot has changed in the Junit world. With Junit5, you can now use
org.junit.jupiter.api.Assertions.assertDoesNotThrow()
Ex:
public void thisMethodDoesNotThrowException(){
System.out.println("Hello There");
}
@Test
public void test_thisMethodDoesNotThrowException(){
org.junit.jupiter.api.Assertions.assertDoesNotThrow(
()-> thisMethodDoesNotThrowException()
);
}
Hope it will help people who are using newer version of Junit5
Go to your projects build settings, and add a user defined setting named SWIFT_ENABLE_BATCH_MODE and set its value to NO.
The other answers answer your question. Another important thing to know about names in Python is that they are either local or global on a per-scope basis.
Consider this, for example:
value = 42
def doit():
print value
value = 0
doit()
print value
You can probably guess that the value = 0 statement will be assigning to a local variable and not affect the value of the same variable declared outside the doit() function. You may be more surprised to discover that the code above won't run. The statement print value inside the function produces an UnboundLocalError.
The reason is that Python has noticed that, elsewhere in the function, you assign the name value, and also value is nowhere declared global. That makes it a local variable. But when you try to print it, the local name hasn't been defined yet. Python in this case does not fall back to looking for the name as a global variable, as some other languages do. Essentially, you cannot access a global variable if you have defined a local variable of the same name anywhere in the function.
You can use System.nanoTime():
long start = System.nanoTime();
// do stuff
long end = System.nanoTime();
long microseconds = (end - start) / 1000;
to get time in nanoseconds but it is a strictly relative measure. It has no absolute meaning. It is only useful for comparing to other nano times to measure how long something took to do.
The error means that you are providing not as much data as the table wp_posts does contain columns. And now the DB engine does not know in which columns to put your data.
To overcome this you must provide the names of the columns you want to fill. Example:
insert into wp_posts (column_name1, column_name2)
values (1, 3)
Look up the table definition and see which columns you want to fill.
And insert means you are inserting a new record. You are not modifying an existing one. Use update for that.
Either use casting as others have already said, or multiply one of the int variables by 1.0:
double firstSolution = ((1.0* b1 * a22 - b2 * a12) / (a11 * a22 - a12 * a21));
If you are open to using Perl, that would be my suggestion. Although there are probably some sed and/or AWK experts that probably know how to do this much easier. If you have a more complex mapping with more than just dbName for your replacements you could extend this pretty easily, but you might just as well put it into a standard Perl script at that point.
perl -p -e 's/\$\{dbName\}/testdb/s' yourfile | mysql
A short Perl script to do something slightly more complicated (handle multiple keys):
#!/usr/bin/env perl
my %replace = ( 'dbName' => 'testdb', 'somethingElse' => 'fooBar' );
undef $/;
my $buf = <STDIN>;
$buf =~ s/\$\{$_\}/$replace{$_}/g for keys %replace;
print $buf;
If you name the above script as replace-script, it could then be used as follows:
replace-script < yourfile | mysql
I note that the question is simply, "Is there any other way to break all of the loops?" I don't see any qualification but that it not be goto, in particular the OP didn't ask for a good way. So, how about we longjmp out of the inner loop? :-)
#include <stdio.h>
#include <setjmp.h>
int main(int argc, char* argv[]) {
int counter = 0;
jmp_buf look_ma_no_goto;
if (!setjmp(look_ma_no_goto)) {
for (int i = 0; i < 1000; i++) {
for (int j = 0; j < 1000; j++) {
if (i == 500 && j == 500) {
longjmp(look_ma_no_goto, 1);
}
counter++;
}
}
}
printf("counter=%d\n", counter);
}
The setjmp function returns twice. The first time, it returns 0 and the program executes the nested for loops. Then when the both i and j are 500, it executes longjmp, which causes setjmp to return again with the value 1, skipping over the loop.
Not only will longjmp get you out of nested loops, it works with nested functions too!
The best I've seen is Zend Guard.
This may be overkill for what you're looking for, but there is an npm package called marky that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer.
You just need to install it via npm and then import the dependency anywhere you'd like to use it.
Here is a link to the npm package:
https://www.npmjs.com/package/marky
An example of use after installing via npm would be as follows:
import * as _M from 'marky';
@Component({
selector: 'app-test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit {
Marky = _M;
}
constructor() {}
ngOnInit() {}
startTimer(key: string) {
this.Marky.mark(key);
}
stopTimer(key: string) {
this.Marky.stop(key);
}
key is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.
Another way of achieving it would be to temporary edit the gitignore file, add the file and then revert back the gitignore. A bit hacky i feel
It's gotten a lot easier these days!
@Repository
public interface PageRepository extends JpaRepository<Page, UUID> {
Boolean existsByName(String name); //Checks if there are any records by name
Boolean existsBy(); // Checks if there are any records whatsoever
}
<ui:include>Most basic way is <ui:include>. The included content must be placed inside <ui:composition>.
Kickoff example of the master page /page.xhtml:
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
<h:head>
<title>Include demo</title>
</h:head>
<h:body>
<h1>Master page</h1>
<p>Master page blah blah lorem ipsum</p>
<ui:include src="/WEB-INF/include.xhtml" />
</h:body>
</html>
The include page /WEB-INF/include.xhtml (yes, this is the file in its entirety, any tags outside <ui:composition> are unnecessary as they are ignored by Facelets anyway):
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
<h2>Include page</h2>
<p>Include page blah blah lorem ipsum</p>
</ui:composition>
This needs to be opened by /page.xhtml. Do note that you don't need to repeat <html>, <h:head> and <h:body> inside the include file as that would otherwise result in invalid HTML.
You can use a dynamic EL expression in <ui:include src>. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).
<ui:define>/<ui:insert>A more advanced way of including is templating. This includes basically the other way round. The master template page should use <ui:insert> to declare places to insert defined template content. The template client page which is using the master template page should use <ui:define> to define the template content which is to be inserted.
Master template page /WEB-INF/template.xhtml (as a design hint: the header, menu and footer can in turn even be <ui:include> files):
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
<h:head>
<title><ui:insert name="title">Default title</ui:insert></title>
</h:head>
<h:body>
<div id="header">Header</div>
<div id="menu">Menu</div>
<div id="content"><ui:insert name="content">Default content</ui:insert></div>
<div id="footer">Footer</div>
</h:body>
</html>
Template client page /page.xhtml (note the template attribute; also here, this is the file in its entirety):
<ui:composition template="/WEB-INF/template.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
<ui:define name="title">
New page title here
</ui:define>
<ui:define name="content">
<h1>New content here</h1>
<p>Blah blah</p>
</ui:define>
</ui:composition>
This needs to be opened by /page.xhtml. If there is no <ui:define>, then the default content inside <ui:insert> will be displayed instead, if any.
<ui:param>You can pass parameters to <ui:include> or <ui:composition template> by <ui:param>.
<ui:include ...>
<ui:param name="foo" value="#{bean.foo}" />
</ui:include>
<ui:composition template="...">
<ui:param name="foo" value="#{bean.foo}" />
...
</ui:composition >
Inside the include/template file, it'll be available as #{foo}. In case you need to pass "many" parameters to <ui:include>, then you'd better consider registering the include file as a tagfile, so that you can ultimately use it like so <my:tagname foo="#{bean.foo}">. See also When to use <ui:include>, tag files, composite components and/or custom components?
You can even pass whole beans, methods and parameters via <ui:param>. See also JSF 2: how to pass an action including an argument to be invoked to a Facelets sub view (using ui:include and ui:param)?
The files which aren't supposed to be publicly accessible by just entering/guessing its URL, need to be placed in /WEB-INF folder, like as the include file and the template file in above example. See also Which XHTML files do I need to put in /WEB-INF and which not?
There doesn't need to be any markup (HTML code) outside <ui:composition> and <ui:define>. You can put any, but they will be ignored by Facelets. Putting markup in there is only useful for web designers. See also Is there a way to run a JSF page without building the whole project?
The HTML5 doctype is the recommended doctype these days, "in spite of" that it's a XHTML file. You should see XHTML as a language which allows you to produce HTML output using a XML based tool. See also Is it possible to use JSF+Facelets with HTML 4/5? and JavaServer Faces 2.2 and HTML5 support, why is XHTML still being used.
CSS/JS/image files can be included as dynamically relocatable/localized/versioned resources. See also How to reference CSS / JS / image resource in Facelets template?
You can put Facelets files in a reusable JAR file. See also Structure for multiple JSF projects with shared code.
For real world examples of advanced Facelets templating, check the src/main/webapp folder of Java EE Kickoff App source code and OmniFaces showcase site source code.
Just simply add to the class of the bootstrap code.

import sys
int(sys.float_info.max)
Try this:
concat(left(datefield,10),left(timefield,8))
10 char on date field based on full date yyyy-MM-dd.
8 char on time field based on full time hh:mm:ss.
It depends on the format you want it. normally you can use script above and you can concat another field or string as you want it.
Because actually date and time field tread as string if you read it. But of course you will got error while update or insert it.
How about
<img style="display: none;" src="a.gif">
That will disable the display completely, and not leave a placeholder
While dbenham's answer is pretty good, relying on IF DEFINED can get you in loads of trouble if the variable you're checking isn't an environment variable. Script variables don't get this special treatment.
While this might seem like some ludicrous undocumented BS, doing a simple shell query of IF with IF /? reveals that,
The DEFINED conditional works just like EXIST except it takes an environment variable name and returns true if the environment variable is defined.
In regards to answering this question, is there a reason to not just use a simple flag after a series of evaluations? That seems the most flexible OR check to me, both in regards to underlying logic and readability. For example:
Set Evaluated_True=false
IF %condition_1%==true (Set Evaluated_True=true)
IF %some_string%=="desired result" (Set Evaluated_True=true)
IF %set_numerical_variable% EQ %desired_numerical_value% (Set Evaluated_True=true)
IF %Evaluated_True%==true (echo This is where you do your passing logic) ELSE (echo This is where you do your failing logic)
Obviously, they can be any sort of conditional evaluation, but I'm just sharing a few examples.
If you wanted to have it all on one line, written-wise, you could just chain them together with && like:
Set Evaluated_True=false
IF %condition_1%==true (Set Evaluated_True=true) && IF %some_string%=="desired result" (Set Evaluated_True=true) && IF %set_numerical_variable% EQ %desired_numerical_value% (Set Evaluated_True=true)
IF %Evaluated_True%==true (echo This is where you do your passing logic) ELSE (echo This is where you do your failing logic)
Pandas is based on NumPy arrays. The key to speed with NumPy arrays is to perform your operations on the whole array at once, never row-by-row or item-by-item.
For example, if close is a 1-d array, and you want the day-over-day percent change,
pct_change = close[1:]/close[:-1]
This computes the entire array of percent changes as one statement, instead of
pct_change = []
for row in close:
pct_change.append(...)
So try to avoid the Python loop for i, row in enumerate(...) entirely, and
think about how to perform your calculations with operations on the entire array (or dataframe) as a whole, rather than row-by-row.
I actually happened to have suffered from the same problem, but none of the provided answers are 100% working with debian:latest, even if they provide good hints.
The biggest difference is that you should make sure both locales and locales-all are installed, the latter already containing en_US.UTF-8, so you don't have to generate it with local-gen or dpkg-reconfigure.
Here's what I've done in my Dockerfile to make it work:

There are many possibilities to do this in R. Here are some of them:
df <- read.table(header = TRUE, text = 'Gene Value
A 12
A 10
B 3
B 5
B 6
C 1
D 3
D 4')
# aggregate
aggregate(df$Value, by = list(df$Gene), max)
aggregate(Value ~ Gene, data = df, max)
# tapply
tapply(df$Value, df$Gene, max)
# split + lapply
lapply(split(df, df$Gene), function(y) max(y$Value))
# plyr
require(plyr)
ddply(df, .(Gene), summarise, Value = max(Value))
# dplyr
require(dplyr)
df %>% group_by(Gene) %>% summarise(Value = max(Value))
# data.table
require(data.table)
dt <- data.table(df)
dt[ , max(Value), by = Gene]
# doBy
require(doBy)
summaryBy(Value~Gene, data = df, FUN = max)
# sqldf
require(sqldf)
sqldf("select Gene, max(Value) as Value from df group by Gene", drv = 'SQLite')
# ave
df[as.logical(ave(df$Value, df$Gene, FUN = function(x) x == max(x))),]
First off, you have to specify you wish to use Document Literal style:
$client = new SoapClient(NULL, array(
'location' => 'https://example.com/path/to/service',
'uri' => 'http://example.com/wsdl',
'trace' => 1,
'use' => SOAP_LITERAL)
);
Then, you need to transform your data into a SoapVar; I've written a simple transform function:
function soapify(array $data)
{
foreach ($data as &$value) {
if (is_array($value)) {
$value = soapify($value);
}
}
return new SoapVar($data, SOAP_ENC_OBJECT);
}
Then, you apply this transform function onto your data:
$data = soapify(array(
'Acquirer' => array(
'Id' => 'MyId',
'UserId' => 'MyUserId',
'Password' => 'MyPassword',
),
));
Finally, you call the service passing the Data parameter:
$method = 'Echo';
$result = $client->$method(new SoapParam($data, 'Data'));
I would first check if your implementation supports isArray:
if (Array.isArray)
return Array.isArray(v);
You could also try using the instanceof operator
v instanceof Array
Use overflow-y. This property is CSS 3.
As Jose answered, screen -d -r should do the trick. This is a combination of two commands, as taken from the man page.
screen -d detaches the already-running screen session, and screen -r reattaches the existing session. By running screen -d -r, you force screen to detach it and then resume the session.
If you use the capital -D -RR, I quote the man page because it's too good to pass up.
Attach here and now. Whatever that means, just do it.
Note: It is always a good idea to check the status of your sessions by means of "screen -list".
In CodeIgniter 3.0-dev (get it from github) this is not working because the CI is search as first letter uppercase.
You can find the code on system/core/Loader.php line 282 or bellow:
$model = ucfirst(strtolower($model));
foreach ($this->_ci_model_paths as $mod_path)
{
if ( ! file_exists($mod_path.'models/'.$path.$model.'.php'))
{
continue;
}
require_once($mod_path.'models/'.$path.$model.'.php');
$CI->$name = new $model();
$this->_ci_models[] = $name;
return $this;
}
This mean that we need to create the file with the following name on application/models/Logon_mode.php
In Designer, activate the centralWidget and assign a layout, e.g. horizontal or vertical layout. Then your QFormLayout will automatically resize.
Always make sure, that all widgets have a layout! Otherwise, automatic resizing will break with that widget!
Controls insist on being too large, and won't resize, in QtDesigner
Try having this in your xml of Edit Text:
android:inputType="numberDecimal"
Say you want to use the in_array, here is how you can make the search case insensitive.
Case insensitive in_array():
foreach($searchKey as $key => $subkey) {
if (in_array(strtolower($subkey), array_map("strtolower", $subarray)))
{
echo "found";
}
}
Normal case sensitive:
foreach($searchKey as $key => $subkey) {
if (in_array("$subkey", $subarray))
{
echo "found";
}
}
You still can insert into complex type in Hive - it works (id is int, colleagues array)
insert into emp (id,colleagues) select 11, array('Alex','Jian') from (select '1')
Every time you used the mysql console, the version is shown.
mysql -u user
Successful console login shows the following which includes the mysql server version.
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1432
Server version: 5.5.9-log Source distribution
Copyright (c) 2000, 2010, Oracle and/or its affiliates. All rights reserved.
Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
You can also check the mysql server version directly by executing the following command:
mysql --version
You may also check the version information from the mysql console itself using the version variables:
mysql> SHOW VARIABLES LIKE "%version%";
Output will be something like this:
+-------------------------+---------------------+
| Variable_name | Value |
+-------------------------+---------------------+
| innodb_version | 1.1.5 |
| protocol_version | 10 |
| slave_type_conversions | |
| version | 5.5.9-log |
| version_comment | Source distribution |
| version_compile_machine | i386 |
| version_compile_os | osx10.4 |
+-------------------------+---------------------+
7 rows in set (0.01 sec)
You may also use this:
mysql> select @@version;
The STATUS command display version information as well.
mysql> STATUS
You can also check the version by executing this command:
mysql -v
It's worth mentioning that if you have encountered something like this:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
you can fix it by:
sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock
This is badly formed HTML. You need to either have a single id or space separated classes. Either way if you're new I'd look into jQuery.
<div id="sub1">some text</div>
or
<div class="sub1 sub2 sub3">some text</div>
If you had the following HTML:
<div id="sub1">some text</div>
<div id="welcome" style="display:none;">Some welcome message</div>
$(document).ready(function() {
$('#sub1').hover(
function() { $('#welcome').show(); },
function() { $('#welcome').hide(); }
);
});
you'd probably want to include the events on your html:
<div id="sub1" onmouseover="showWelcome();" onmouseout="hideWelcome();">some text</div>
then your javascript would have these two functions
function showWelcome()
{
var welcome = document.getElementById('welcome');
welcome.style.display = 'block';
}
function hideWelcome()
{
var welcome = document.getElementById('welcome');
welcome.style.display = 'none';
}
Please note: this javascript doesn't take cross browser issues into consideration. for this you'd need to elaborate on your code, just another reason to use jquery.
You can't rewrite a line without rewriting the entire file (unless the lines happen to be the same length). If your files are small then reading the entire target file into memory and then writing it out again might make sense. You can do that like this:
using System;
using System.IO;
class Program
{
static void Main(string[] args)
{
int line_to_edit = 2; // Warning: 1-based indexing!
string sourceFile = "source.txt";
string destinationFile = "target.txt";
// Read the appropriate line from the file.
string lineToWrite = null;
using (StreamReader reader = new StreamReader(sourceFile))
{
for (int i = 1; i <= line_to_edit; ++i)
lineToWrite = reader.ReadLine();
}
if (lineToWrite == null)
throw new InvalidDataException("Line does not exist in " + sourceFile);
// Read the old file.
string[] lines = File.ReadAllLines(destinationFile);
// Write the new file over the old file.
using (StreamWriter writer = new StreamWriter(destinationFile))
{
for (int currentLine = 1; currentLine <= lines.Length; ++currentLine)
{
if (currentLine == line_to_edit)
{
writer.WriteLine(lineToWrite);
}
else
{
writer.WriteLine(lines[currentLine - 1]);
}
}
}
}
}
If your files are large it would be better to create a new file so that you can read streaming from one file while you write to the other. This means that you don't need to have the whole file in memory at once. You can do that like this:
using System;
using System.IO;
class Program
{
static void Main(string[] args)
{
int line_to_edit = 2;
string sourceFile = "source.txt";
string destinationFile = "target.txt";
string tempFile = "target2.txt";
// Read the appropriate line from the file.
string lineToWrite = null;
using (StreamReader reader = new StreamReader(sourceFile))
{
for (int i = 1; i <= line_to_edit; ++i)
lineToWrite = reader.ReadLine();
}
if (lineToWrite == null)
throw new InvalidDataException("Line does not exist in " + sourceFile);
// Read from the target file and write to a new file.
int line_number = 1;
string line = null;
using (StreamReader reader = new StreamReader(destinationFile))
using (StreamWriter writer = new StreamWriter(tempFile))
{
while ((line = reader.ReadLine()) != null)
{
if (line_number == line_to_edit)
{
writer.WriteLine(lineToWrite);
}
else
{
writer.WriteLine(line);
}
line_number++;
}
}
// TODO: Delete the old file and replace it with the new file here.
}
}
You can afterwards move the file once you are sure that the write operation has succeeded (no excecption was thrown and the writer is closed).
Note that in both cases it is a bit confusing that you are using 1-based indexing for your line numbers. It might make more sense in your code to use 0-based indexing. You can have 1-based index in your user interface to your program if you wish, but convert it to a 0-indexed before sending it further.
Also, a disadvantage of directly overwriting the old file with the new file is that if it fails halfway through then you might permanently lose whatever data wasn't written. By writing to a third file first you only delete the original data after you are sure that you have another (corrected) copy of it, so you can recover the data if the computer crashes halfway through.
A final remark: I noticed that your files had an xml extension. You might want to consider if it makes more sense for you to use an XML parser to modify the contents of the files instead of replacing specific lines.
You can also extract the event code from the HTML, like this :
<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>
<script>
function selectAll(frmElement, chkElement) {
// ...
}
document.getElementById("check_all_1").onclick = function() {
selectAll(document.wizard_form, this);
}
</script>
I've been using this:
cat myfile.txt | wc -l
I prefer it over the accepted answer because it does not print the filename, and you don't have to use awk to fix that. Accepted answer:
wc -l myfile.txt
But I think the best one is GGB667's answer:
wc -l < myfile.txt
I will probably be using that from now on. It's slightly shorter than my way. I am putting up my old way of doing it in case anyone prefers it. The output is the same with those two methods.
You could manually adjust the spacing using plt.subplots_adjust(top=0.85):
import numpy as np
import matplotlib.pyplot as plt
f = np.random.random(100)
g = np.random.random(100)
fig = plt.figure()
fig.suptitle('Long Suptitle', fontsize=24)
plt.subplot(121)
plt.plot(f)
plt.title('Very Long Title 1', fontsize=20)
plt.subplot(122)
plt.plot(g)
plt.title('Very Long Title 2', fontsize=20)
plt.subplots_adjust(top=0.85)
plt.show()
You need to concatenate your string.
document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';
The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.
I would even suggest creating the string separate:
function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
var urlString = 'url(buttons/' + imagePrefix + '.png)';
document.getElementById(tabName).style.backgroundImage = urlString;
}
As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html
The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.
When working to create Cross Browser Favicons (including touch icons) there are several things to consider.
The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon" for IE to recognize the icon it needs the word shortcut which is not standard. Also we wrap the .ico favicon in a IE conditional comment because Chrome and Safari will use the .ico file if it is present, despite other options available, not what we would like.
The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.
For the rest of the browsers we are going to use the standard way to cite a favicon:
<link rel="icon" href="path/to/favicon.png">
This icon should be 196x196 pixels in size to cover all devices that may use this icon.
To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
Using rel="apple-touch-icon-precomposed" will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon". This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed".
As a note: Chrome for Android states:
The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).
Custom Tiles for IE 11+ on Windows 8.1+
IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.
Microsoft recommends creating a few tiles at the following size:
Small: 128 x 128
Medium: 270 x 270
Wide: 558 x 270
Large: 558 x 558
These should be transparent images as we will define a color background next.
Once these images are created you should create an xml file called browserconfig.xml with the following code:
<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
<msapplication>
<tile>
<square70x70logo src="images/smalltile.png"/>
<square150x150logo src="images/mediumtile.png"/>
<wide310x150logo src="images/widetile.png"/>
<square310x310logo src="images/largetile.png"/>
<TileColor>#009900</TileColor>
</tile>
</msapplication>
</browserconfig>
Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head:
<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />
For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.
Putting it all together:
To put it all together the above code would look like this:
<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. -->
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">
Windows Phone Live Tiles
If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:
Here are detailed instructions from Microsoft but here is a synopsis:
Step 1
Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.
Step 2
Add a hidden overlay of this image. Here is example code from Microsoft:
<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
<img src="customtile.png" width="320" height="320" />
<div style='margin-top: 40px'>
Add text/graphic asking user to pin to start using the menu...
</div>
</div>
Step 3
You then can add thew following line to add a pin to start link:
<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>
Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.
Step 4
Next you add some JS to toggle the overlay visibility
<script>
function ToggleTileOverlay() {
var newVisibility = (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
document.getElementById('TileOverlay').style.visibility = newVisibility;
}
</script>
Note on Sizes
I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.
Further Reading
For those who would like more details see the links below:
First you need to prepare your url to accept the param in the regex: (urls.py)
url(r'^panel/person/(?P<person_id>[0-9]+)$', 'apps.panel.views.person_form', name='panel_person_form'),
So you use this in your template:
{% url 'panel_person_form' person_id=item.id %}
If you have more than one param, you can change your regex and modify the template using the following:
{% url 'panel_person_form' person_id=item.id group_id=3 %}
I know this is slightly off-topic, since some comments mentioned the ax.set_yscale('log') to be "nicest" solution I thought a rebuttal could be due. I would not recommend using ax.set_yscale('log') for histograms and bar plots. In my version (0.99.1.1) i run into some rendering problems - not sure how general this issue is. However both bar and hist has optional arguments to set the y-scale to log, which work fine.

There's so many answers out there saying to reinstall mysql or use some combo of
mysqld_safe --skip-grant-tables
and / or
UPDATE mysql.user SET Password=PASSWORD('password')
and / or something else ...
... None of it was working for me
Here's what worked for me, on Ubuntu 18.04, from the top
With special credit to this answer for digging me out of the frustration on this ...
$ sudo apt install mysql-server
$ sudo cat /etc/mysql/debian.cnf
Note the lines which read:
user = debian-sys-maint
password = blahblahblah
Then:
$ mysql -u debian-sys-maint -p
Enter password: // type 'blahblahblah', ie. password from debian.cnf
mysql> USE mysql
mysql> SELECT User, Host, plugin FROM mysql.user;
+------------------+-----------+-----------------------+
| User | Host | plugin |
+------------------+-----------+-----------------------+

Or:
// For MySQL 5.7+
UPDATE mysql.user SET authentication_string=PASSWORD('new_password') where user='root';
Then:

$ sudo service mysql restart
$ mysql -u root -p
Enter password: // Yay! 'new_password' now works!
?month states:
Date-time must be a POSIXct, POSIXlt, Date, Period, chron, yearmon, yearqtr, zoo, zooreg, timeDate, xts, its, ti, jul, timeSeries, and fts objects.
Your object is a factor, not even a character vector (presumably because of stringsAsFactors = TRUE). You have to convert your vector to some datetime class, for instance to POSIXlt:
library(lubridate)
some_date <- c("01/02/1979", "03/04/1980")
month(as.POSIXlt(some_date, format="%d/%m/%Y"))
[1] 2 4
There's also a convenience function dmy, that can do the same (tip proposed by @Henrik):
month(dmy(some_date))
[1] 2 4
Going even further, @IShouldBuyABoat gives another hint that dd/mm/yyyy character formats are accepted without any explicit casting:
month(some_date)
[1] 2 4
For a list of formats, see ?strptime. You'll find that "standard unambiguous format" stands for
The default formats follow the rules of the ISO 8601 international standard which expresses a day as "2001-02-28" and a time as "14:01:02" using leading zeroes as here.
What you want to do is a combination of part of 1 and all of 2.
You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.
But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.
From the javadoc:
Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.
The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.
Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:
import static org.mockito.Mockito.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
class ClassWithStatics {
public static String getString() {
return "String";
}
public static int getInt() {
return 1;
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
@Test
public void test() {
PowerMockito.mockStatic(ClassWithStatics.class);
when(ClassWithStatics.getString()).thenReturn("Hello!");
System.out.println("String: " + ClassWithStatics.getString());
System.out.println("Int: " + ClassWithStatics.getInt());
}
}
The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.
To say what others have in a different way: yes, it is a decorator.
In Python, it's like:
This can be used for all kinds of useful things, made possible because functions are objects and just necessary just instructions.
The easiest way is:
var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");
Objective-C is a more perfect superset of C. In C and Objective-C implicit casting from void* to a struct pointer is allowed.
Foo* bar = malloc(sizeof(Foo));
C++ will not compile unless the void pointer is explicitly cast:
Foo* bar = (Foo*)malloc(sizeof(Foo));
The relevance of this to every day programming is zero, just a fun trivia fact.
Another one, it is an older project but shares the complete source code: http://telnetcsharp.codeplex.com/
Dynamic linking (.so) can be much much faster than static linking (.a). Especially when you have a slow network drive. This is since you have all of the code in the .a file which needs to be processed and written out. In addition, a much larger executable file needs to be written out to the disk.
You need to check if is a string to avoid getting a child element
var getIdFromDomObj = function(domObj){
var id = domObj.id;
return typeof id === 'string' ? id : false;
};
(I have moved this answer from another question that was more or less a dupe of this one.)
The answer to your question is implementation specific and may vary across compilers and processor architectures. However, here is a simplified explanation.
new or malloc) are satisfied by creating a suitable block from one of the free blocks. This requires updating list of blocks on the heap. This meta information about the blocks on the heap is also stored on the heap often in a small area just in front of every block.
Can a function be allocated on the heap instead of a stack?
No, activation records for functions (i.e. local or automatic variables) are allocated on the stack that is used not only to store these variables, but also to keep track of nested function calls.
How the heap is managed is really up to the runtime environment. C uses malloc and C++ uses new, but many other languages have garbage collection.
However, the stack is a more low-level feature closely tied to the processor architecture. Growing the heap when there is not enough space isn't too hard since it can be implemented in the library call that handles the heap. However, growing the stack is often impossible as the stack overflow only is discovered when it is too late; and shutting down the thread of execution is the only viable option.

Just ran into this issue on a current LG phone on a windows computer. Everything from developer options was enabled correctly, but wasn't able to see the device through ABD. Needed install drivers which I was able to do from the phone.
After connecting through USB and allowing the connection, I tapped the USB connection type notification and on the screen where you select the type of USB connection (MTP, PTP, etc..) I tapped the three dot icon in the top right hand corner of the screen and selected to install the PC drivers. After installing the drivers on my PC I was able to connect through ABD to debug.
Of course it is right what you say at the beginning, and C logical operator && and || are what you usually use to "connect" conditions (expressions that can be evaluated as true or false); the comma operator is not a logical operator and its use in that example makes no sense, as explained by other users. You can use it e.g. to "concatenate" statements in the for itself: you can initialize and update j altogether with i; or use the comma operator in other ways
#include <stdio.h>
int main(void) // as std wants
{
int i, j;
// init both i and j; condition, we suppose && is the "original"
// intention; update i and j
for(i=0, j=2; j>=0 && i<=5; i++, j--)
{
printf("%d ", i+j);
}
return 0;
}

Use the HAVING, not WHERE clause, for aggregate result comparison.
Taking the query at face value:
SELECT *
FROM db.table
HAVING COUNT(someField) > 1
Ideally, there should be a GROUP BY defined for proper valuation in the HAVING clause, but MySQL does allow hidden columns from the GROUP BY...
Is this in preparation for a unique constraint on someField? Looks like it should be...
Through Code:
Your best bet is to use parse inside a try-catch and catch exception in case of failed parsing. (I am not aware of any TryParse method).
(Using JSON.Net)
Simplest way would be to Parse the string using JToken.Parse, and also to check if the string starts with { or [ and ends with } or ] respectively (added from this answer):
private static bool IsValidJson(string strInput)
{
if (string.IsNullOrWhiteSpace(strInput)) { return false;}
strInput = strInput.Trim();
if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
(strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
{
try
{
var obj = JToken.Parse(strInput);
return true;
}
catch (JsonReaderException jex)
{
//Exception in parsing json
Console.WriteLine(jex.Message);
return false;
}
catch (Exception ex) //some other exception
{
Console.WriteLine(ex.ToString());
return false;
}
}
else
{
return false;
}
}
The reason to add checks for { or [ etc was based on the fact that JToken.Parse would parse the values such as "1234" or "'a string'" as a valid token. The other option could be to use both JObject.Parse and JArray.Parse in parsing and see if anyone of them succeeds, but I believe checking for {} and [] should be easier. (Thanks @RhinoDevel for pointing it out)
Without JSON.Net
You can utilize .Net framework 4.5 System.Json namespace ,like:
string jsonString = "someString";
try
{
var tmpObj = JsonValue.Parse(jsonString);
}
catch (FormatException fex)
{
//Invalid json format
Console.WriteLine(fex);
}
catch (Exception ex) //some other exception
{
Console.WriteLine(ex.ToString());
}
(But, you have to install System.Json through Nuget package manager using command: PM> Install-Package System.Json -Version 4.0.20126.16343 on Package Manager Console) (taken from here)
Non-Code way:
Usually, when there is a small json string and you are trying to find a mistake in the json string, then I personally prefer to use available on-line tools. What I usually do is:
On linux, find dblink.sql, then execute in the postgresql console something like this to create all required functions:
\i /usr/share/postgresql/8.4/contrib/dblink.sql
you might need to install the contrib packages: sudo apt-get install postgresql-contrib
I solved it by using the developer tools for IE7 (its a toolbar) and adding a negative z-index to the container of the div that will be below that the other div.
$('select#id').find('option').each(function() {
alert($(this).val());
});

Made a tiny script to make it slightly easier to find the commit one is looking for:
git fsck --lost-found | grep commit | cut -d ' ' -f 3 | xargs -i git show \{\} | egrep '^commit |Date:'
Yes, it can be made considerably prettier with awk or something like it, but it's simple and I just needed it. Might save someone else 30 seconds.

I had a similar problem:
docker: Error response from daemon: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"sh\": executable file not found in $PATH": unknown.
In my case, I know the image works in other places, then was a corrupted local image.
I solved the issue removing the image (docker rmi <imagename>) and pulling it again(docker pull <imagename>).
I did a docker system prune too, but I think it's not mandatory.
MySQL recommends using indexes for a variety of reasons including elimination of rows between conditions: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html
This makes your datetime column an excellent candidate for an index if you are going to be using it in conditions frequently in queries. If your only condition is BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY) and you have no other index in the condition, MySQL will have to do a full table scan on every query. I'm not sure how many rows are generated in 30 days, but as long as it's less than about 1/3 of the total rows it will be more efficient to use an index on the column.
Your question about creating an efficient database is very broad. I'd say to just make sure that it's normalized and all appropriate columns are indexed (i.e. ones used in joins and where clauses).
Your CA file must have been in a binary X.509 format instead of Base64 encoding; it needs to be a regular DER or PEM in order for it to be added successfully to the list of trusted CAs on your server.
To proceed, do place your CA file inside your /usr/share/pki/ca-trust-source/anchors/ directory, then run the command line below (you might need sudo privileges based on your settings);
# CentOS 7, Red Hat 7, Oracle Linux 7
update-ca-trust
Please note that all trust settings available in the /usr/share/pki/ca-trust-source/anchors/ directory are interpreted with a lower priority compared to the ones placed under the /etc/pki/ca-trust/source/anchors/ directory which may be in the extended BEGIN TRUSTED file format.
For Ubuntu and Debian systems, /usr/local/share/ca-certificates/ is the preferred directory for that purpose.
As such, you need to place your CA file within the /usr/local/share/ca-certificates/ directory, then update the of trusted CAs by running, with sudo privileges where required, the command line below;
update-ca-certificates
Always best to have a primary key. This way it meets first normal form and allows you to continue along the database normalization path.
As stated by others, there are some reasons not to have a primary key, but most will not be harmed if there is a primary key
You can use max-height in an inline style attribute, as below:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
To use scrolling with content that overflows a given max-height, you can alternatively try the following:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>
To restrict the height to a fixed value you can use something like this.
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
Specify the same value for both max-height and min-height (either in pixels or in points – as long as it’s consistent).
You can also put the same styles in css class in a stylesheet (or a style tag as shown below) and then include the same in your tag. See below:
Style Code:
.fixed-panel {
min-height: 10;
max-height: 10;
overflow-y: scroll;
}
Apply Style :
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>
Hope this helps with your need.

I use a similar technique to what @Sarfraz posted, except instead of hiding elements, I just manipulate the class of the image that I'm loading.
<style type="text/css">
.loading { background-image: url(loading.gif); }
.loaderror { background-image: url(loaderror.gif); }
</style>
...
<img id="image" class="loading" />
...
<script type="text/javascript">
var img = new Image();
img.onload = function() {
i = document.getElementById('image');
i.removeAttribute('class');
i.src = img.src;
};
img.onerror = function() {
document.getElementById('image').setAttribute('class', 'loaderror');
};
img.src = 'http://path/to/image.png';
</script>
In my case, sometimes images don't load, so I handle the onerror event to change the image class so it displays an error background image (rather than the browser's broken image icon).
You should \usepackage{longtable}.
While there are suggestions above for "doing it the python way", if one wants to really have a logic based on EOF, then I suppose using exception handling is the way to do it --
try:
line = raw_input()
... whatever needs to be done incase of no EOF ...
except EOFError:
... whatever needs to be done incase of EOF ...
Example:
$ echo test | python -c "while True: print raw_input()"
test
Traceback (most recent call last):
File "<string>", line 1, in <module>
EOFError: EOF when reading a line
Or press Ctrl-Z at a raw_input() prompt (Windows, Ctrl-Z Linux)
Darren Davies is partially correct in saying that you should use a salt - there are several issues with his claim that MD5 is insecure.
You've said that you have to insert the password using an Md5 hash, but that doesn't really tell us why. Is it because that's the format used when validatinb the password? Do you have control over the code which validates the password?
The thing about using a salt is that it avoids the problem where 2 users have the same password - they'll also have the same hash - not a desirable outcome. By using a diferent salt for each password then this does not arise (with very large volumes of data there is still a risk of collisions arising from 2 different passwords - but we'll ignore that for now).
So you can aither generate a random value for the salt and store that in the record too, or you could use some of the data you already hold - such as the username:
$query="INSERT INTO ptb_users (id,
user_id,
first_name,
last_name,
email )
VALUES('NULL',
'NULL',
'".$firstname."',
'".$lastname."',
'".$email."',
MD5('"$user_id.$password."')
)";
(I am assuming that you've properly escaped all those strings earlier in your code)
With me was the same problem, but it was caused, because i was using the mysql server on 32 (bit) and the workbench was running on 64(bit) version. the server and the workbench need to has the same version.
In response to MK_Dev, one is able to iterate, but not consecutively (for that, obviously an array is needed).
A quick Google search brings up hash tables in JavaScript.
Example code for looping over values in a hash (from the aforementioned link):
var myArray = new Array();
myArray['one'] = 1;
myArray['two'] = 2;
myArray['three'] = 3;
// Show the values stored
for (var i in myArray) {
alert('key is: ' + i + ', value is: ' + myArray[i]);
}
Assuming you're using a std::ofstream to write to file, the following snippet will write a std::string to file in human readable form:
std::ofstream file("filename");
std::string my_string = "Hello text in file\n";
file << my_string;
Did you add the Select() after the Where() or before?
You should add it after, because of the concurrency logic:
1 Take the entire table
2 Filter it accordingly
3 Select only the ID's
4 Make them distinct.
If you do a Select first, the Where clause can only contain the ID attribute because all other attributes have already been edited out.
Update: For clarity, this order of operators should work:
db.Items.Where(x=> x.userid == user_ID).Select(x=>x.Id).Distinct();
Probably want to add a .toList() at the end but that's optional :)

I don't know, it works fine for me. Exact commands:
import scipy, pylab
ax = pylab.subplot(111)
ax.scatter(scipy.randn(100), scipy.randn(100), c='b')
ax.scatter(scipy.randn(100), scipy.randn(100), c='r')
ax.figure.show()
So what will happen if two threads attack a volatile primitive variable at same time?
Usually each one can increment the value. However sometime, both will update the value at the same time and instead of incrementing by 2 total, both thread increment by 1 and only 1 is added.
Does this mean that whosoever takes lock on it, that will be setting its value first.
There is no lock. That is what synchronized is for.
And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?
Yes,
What is the difference between Atomic and volatile keyword?
AtomicXxxx wraps a volatile so they are basically same, the difference is that it provides higher level operations such as CompareAndSwap which is used to implement increment.
AtomicXxxx also supports lazySet. This is like a volatile set, but doesn't stall the pipeline waiting for the write to complete. It can mean that if you read a value you just write you might see the old value, but you shouldn't be doing that anyway. The difference is that setting a volatile takes about 5 ns, bit lazySet takes about 0.5 ns.
If you'd like to use Code Behind, may I suggest the following solution for an asp:button -
ASPX Page
<asp:Button ID="btnRecover" runat="server" Text="Recover" OnClick="btnRecover_Click" />
Code Behind
protected void btnRecover_Click(object sender, EventArgs e)
{
var recoveryId = Guid.Parse(lbRecovery.SelectedValue);
var url = string.Format("{0}?RecoveryId={1}", @"../Recovery.aspx", vehicleId);
// Response.Redirect(url); // Old way
Response.Write("<script> window.open( '" + url + "','_blank' ); </script>");
Response.End();
}
You can also simply do
session.setConfig("StrictHostKeyChecking", "no");
It's not secure and it's a workaround not suitable for live environment as it will disable globally known host keys checking.
