I guess you're learning how to Python. The other answers are right. But I am going to answer your main question: "how to calculate percentage in python"
Although it works the way you did it, it doesn´t look very pythonic. Also, what happens if you need to add a new subject? You'll have to add another variable, use another input, etc. I guess you want the average of all marks, so you will also have to modify the count of the subjects everytime you add a new one! Seems a mess...
I´ll throw a piece of code where the only thing you'll have to do is to add the name of the new subject in a list. If you try to understand this simple piece of code, your Python coding skills will experiment a little bump.
#!/usr/local/bin/python2.7
marks = {} #a dictionary, it's a list of (key : value) pairs (eg. "Maths" : 34)
subjects = ["Tamil","English","Maths","Science","Social"] # this is a list
#here we populate the dictionary with the marks for every subject
for subject in subjects:
marks[subject] = input("Enter the " + subject + " marks: ")
#and finally the calculation of the total and the average
total = sum(marks.itervalues())
average = float(total) / len(marks)
print ("The total is " + str(total) + " and the average is " + str(average))
Here you can test the code and experiment with it.

Q: What is a lambda expression in C++11?
A: Under the hood, it is the object of an autogenerated class with overloading operator() const. Such object is called closure and created by compiler. This 'closure' concept is near with the bind concept from C++11. But lambdas typically generate better code. And calls through closures allow full inlining.
Q: When would I use one?
A: To define "simple and small logic" and ask compiler perform generation from previous question. You give a compiler some expressions which you want to be inside operator(). All other stuff compiler will generate to you.
Q: What class of problem do they solve that wasn't possible prior to their introduction?
A: It is some kind of syntax sugar like operators overloading instead of functions for custom add, subrtact operations...But it save more lines of unneeded code to wrap 1-3 lines of real logic to some classes, and etc.! Some engineers think that if the number of lines is smaller then there is a less chance to make errors in it (I'm also think so)
Example of usage
auto x = [=](int arg1){printf("%i", arg1); };
void(*f)(int) = x;
f(1);
x(1);
Extras about lambdas, not covered by question. Ignore this section if you're not interest
1. Captured values. What you can to capture
1.1. You can reference to a variable with static storage duration in lambdas. They all are captured.
1.2. You can use lambda for capture values "by value". In such case captured vars will be copied to the function object (closure).
[captureVar1,captureVar2](int arg1){}
1.3. You can capture be reference. & -- in this context mean reference, not pointers.
[&captureVar1,&captureVar2](int arg1){}
1.4. It exists notation to capture all non-static vars by value, or by reference
[=](int arg1){} // capture all not-static vars by value
[&](int arg1){} // capture all not-static vars by reference
1.5. It exists notation to capture all non-static vars by value, or by reference and specify smth. more. Examples: Capture all not-static vars by value, but by reference capture Param2
[=,&Param2](int arg1){}
Capture all not-static vars by reference, but by value capture Param2
[&,Param2](int arg1){}
2. Return type deduction
2.1. Lambda return type can be deduced if lambda is one expression. Or you can explicitly specify it.
[=](int arg1)->trailing_return_type{return trailing_return_type();}
If lambda has more then one expression, then return type must be specified via trailing return type. Also, similar syntax can be applied to auto functions and member-functions
3. Captured values. What you can not capture
3.1. You can capture only local vars, not member variable of the object.
4. ?onversions
4.1 !! Lambda is not a function pointer and it is not an anonymous function, but capture-less lambdas can be implicitly converted to a function pointer.
p.s.
More about lambda grammar information can be found in Working draft for Programming Language C++ #337, 2012-01-16, 5.1.2. Lambda Expressions, p.88
In C++14 the extra feature which has named as "init capture" have been added. It allow to perform arbitarily declaration of closure data members:
auto toFloat = [](int value) { return float(value);};
auto interpolate = [min = toFloat(0), max = toFloat(255)](int value)->float { return (value - min) / (max - min);};
try this
select max(salary) as first,
(select salary from employee order by salary desc limit 1, 1) as second
from employee limit 1

For a very specific reason Type Nullable<int>
put your cursor on Nullable and hit F12 - The Metadata provides the reason (Note the struct constraint):
public struct Nullable<T> where T : struct
{
...
}
In java config,make sure you have import your config in RootConfig like this @Import(PersistenceJPAConfig.class)
In the example you give, you're perfectly right, you have to set the title attribute.
If the aria-label
is one tool used by assistive technologies (like screen readers), it is not natively supported on browsers and has no effect on them. It won't be of any help to most of the people targetted by the WCAG (except screen reader users), for instance a person with intellectal disabilities.
The "X" is not sufficient enough to give information to the action led by the button (think about someone with no computer knowledge). It might mean "close", "delete", "cancel", "reduce", a strange cross, a doodle, nothing.
Despite the fact that the W3C seems to promote the aria-label
rather that the title
attribute here: http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140916/ARIA14 in a similar example, you can see that the technology support does not include standard browsers : http://www.w3.org/WAI/WCAG20/Techniques/ua-notes/aria#ARIA14
In fact aria-label
, in this exact situation might be used to give more context to an action:
For instance, blind people do not perceive popups like those of us with good vision, it's like a change of context. "Back to the page" will be a more convenient alternative for a screen reader, when "Close" is more significant for someone with no screen reader.
<button
aria-label="Back to the page"
title="Close" onclick="myDialog.close()">X</button>
You can use Analyze APK...
from the Build menu in Android Studio, it will display the package name at the top of new window.
The command yum
that you launch was executed properly. It returns a non zero status which means that an error occured during the processing of the command. You probably want to add some argument to your yum
command to fix that.
Your code could show this error this way:
import subprocess
try:
subprocess.check_output("dir /f",shell=True,stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as e:
raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))
You may use negative superthick semi-transparent border...
.red {_x000D_
outline: 100px solid rgba(255, 0, 0, 0.5) !important;_x000D_
outline-offset: -100px;_x000D_
overflow: hidden;_x000D_

This solution requires you to know exact sizes of covered object.
Most of the answers that are using Parcelable concept here are in Java code. It is easier to do it in Kotlin.
Just annotate your enum class with @Parcelize and implement Parcelable interface.
@Parcelize
enum class ViewTypes : Parcelable {
TITLE, PRICES, COLORS, SIZES
}
Maybe with Dispatch
:
from win32com.client import Dispatch
zk = Dispatch("zkemkeeper.ZKEM")
Where zkemkeeper is a registered DLL file on the system... After that, you can access functions just by calling them:
zk.Connect_Net(IP_address, port)
The code commented works as well, just choose which do you prefer
import numpy as np
from PIL import Image
def convert_from_cv2_to_image(img: np.ndarray) -> Image:
# return Image.fromarray(cv2.cvtColor(img, cv2.COLOR_BGR2RGB))
return Image.fromarray(img)
def convert_from_image_to_cv2(img: Image) -> np.ndarray:
# return cv2.cvtColor(numpy.array(img), cv2.COLOR_RGB2BGR)
return np.asarray(img)
Use row_count - your_desired_offset
So if we had 10 rows and want to offset 3
10 - 3 = 7
Now the query delete from table where this = that order asc limit 7
keeps the last 3, and order desc
to keep the first 3:
$row_count - $offset = $limit
Delete from table where entry = criteria order by ts asc limit $limit
You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:
import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values
... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.
Can't import all at once but can use following combination:
ALT
+ Enter
--> Show intention actions and quick-fixes.
F2
--> Next highlighted error.
Go to system preferences, then "MySQL". Click on "Start MySQL Server".
The following example creates a SqlConnection and a SqlTransaction. It also demonstrates how to use the BeginTransaction, Commit, and Rollback methods. The transaction is rolled back on any error, or if it is disposed without first being committed. Try/Catch error handling is used to handle any errors when attempting to commit or roll back the transaction.
private static void ExecuteSqlTransaction(string connectionString)
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
SqlCommand command = connection.CreateCommand();
SqlTransaction transaction;
// Start a local transaction.
transaction = connection.BeginTransaction("SampleTransaction");
// Must assign both transaction object and connection
// to Command object for a pending local transaction
command.Connection = connection;
command.Transaction = transaction;
try
{
command.CommandText =
"Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
command.ExecuteNonQuery();
command.CommandText =
"Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
command.ExecuteNonQuery();
// Attempt to commit the transaction.
transaction.Commit();
Console.WriteLine("Both records are written to database.");
}
catch (Exception ex)
{
Console.WriteLine("Commit Exception Type: {0}", ex.GetType());
Console.WriteLine(" Message: {0}", ex.Message);
// Attempt to roll back the transaction.
try
{
transaction.Rollback();
}
catch (Exception ex2)
{
// This catch block will handle any errors that may have occurred
// on the server that would cause the rollback to fail, such as
// a closed connection.
Console.WriteLine("Rollback Exception Type: {0}", ex2.GetType());
Console.WriteLine(" Message: {0}", ex2.Message);
}
}
}
}
you can use simple if condition like:
if(round(var) != var)
If you just want to rename and don't mind using an external tool, then you can use rnm. The command would be:
#on current folder
rnm -dp -1 -fo -ssf '_dbg' -rs '/_dbg//' *
-dp -1
will make it recursive to all subdirectories.
-fo
implies file only mode.
-ssf '_dbg'
searches for files with _dbg in the filename.
-rs '/_dbg//'
replaces _dbg with empty string.
You can run the above command with the path of the CURRENT_FOLDER too:
rnm -dp -1 -fo -ssf '_dbg' -rs '/_dbg//' /path/to/the/directory
private final void focusOnView(){
your_scrollview.post(new Runnable() {
@Override
public void run() {
your_scrollview.scrollTo(0, your_EditBox.getBottom());
}
});
}
X.each_with_index do |item, index|
puts "current_index: #{index}"
end
For dynamic cells, rowHeight
set on the UITableView
always overrides the individual cells' rowHeight
.
This behavior is, IMO, a bug. Anytime you have to manage your UI in two places it is prone to error. For example, if you change your cell size in the storyboard, you have to remember to change them in the heightForRowAtIndexPath:
as well. Until Apple fixes the bug, the current best workaround is to override heightForRowAtIndexPath:
, but use the actual prototype cells from the storyboard to determine the height rather than using magic numbers. Here's an example:
- (CGFloat)tableView:(UITableView *)tableView
heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
/* In this example, there is a different cell for
the top, middle and bottom rows of the tableView.
Each type of cell has a different height.
self.model contains the data for the tableview
*/
static NSString *CellIdentifier;
if (indexPath.row == 0)
CellIdentifier = @"CellTop";
else if (indexPath.row + 1 == [self.model count] )
CellIdentifier = @"CellBottom";
else
CellIdentifier = @"CellMiddle";
UITableViewCell *cell =
[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
return cell.bounds.size.height;
}
This will ensure any changes to your prototype cell heights will automatically be picked up at runtime and you only need to manage your UI in one place: the storyboard.
I have just experienced this issue in one of my MySQL db's and I looked at the phpMyAdmin answer here. However the best way I fixed it in phpMyAdmin was in the affected table, drop the id column and make a fresh/new id column (adding A-I -autoincrement-). This restored my table id correctly-simples! Hope that helps (no MySQL code needed-I hope to learn to use that but later!) anyone else with this problem.
I forgot that I had already an unused labs
branch. Deleting it solved my problem:
git branch -d labs
git checkout -b labs/feature
Explanation:
Each name can only be a parent branch or a normal branch, not both. Thats why the branches labs
and labs/feature
can't exists both at the same time.
The reason: Branches are stored in the file system and there you also can't have a file labs
and a directory labs
at the same level.
Since Spark 1.5 you can use a number of date processing functions:
pyspark.sql.functions.year
pyspark.sql.functions.month
pyspark.sql.functions.dayofmonth
pyspark.sql.functions.dayofweek()
pyspark.sql.functions.dayofyear
pyspark.sql.functions.weekofyear()
import datetime
from pyspark.sql.functions import year, month, dayofmonth
elevDF = sc.parallelize([
(datetime.datetime(1984, 1, 1, 0, 0), 1, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 2, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 3, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 4, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 5, 638.55)
]).toDF(["date", "hour", "value"])
elevDF.select(
year("date").alias('year'),
month("date").alias('month'),
dayofmonth("date").alias('day')
).show()
# +----+-----+---+
# |year|month|day|
# +----+-----+---+
# |1984| 1| 1|
# |1984| 1| 1|
# |1984| 1| 1|
# |1984| 1| 1|
# |1984| 1| 1|
# +----+-----+---+
You can use simple map
as with any other RDD:
elevDF = sqlContext.createDataFrame(sc.parallelize([
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=1, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=2, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=3, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=4, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=5, value=638.55)]))
(elevDF
.map(lambda (date, hour, value): (date.year, date.month, date.day))
.collect())
and the result is:
[(1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1)]
Btw: datetime.datetime
stores an hour anyway so keeping it separately seems to be a waste of memory.
I used this set up in a react app that works. I created a config file named configstrp.js that contains the following:
module.exports = {
ngrok: {
// use the local frontend port to connect
enabled: process.env.NODE_ENV !== 'production',
port: process.env.PORT || 3000,
subdomain: process.env.NGROK_SUBDOMAIN,
authtoken: process.env.NGROK_AUTHTOKEN
}, }
Require the file in the server.
const configstrp = require('./config/configstrp.js');
const ngrok = configstrp.ngrok.enabled ? require('ngrok') : null;
and connect as such
if (ngrok) {
console.log('If nGronk')
ngrok.connect(
{
addr: configstrp.ngrok.port,
subdomain: configstrp.ngrok.subdomain,
authtoken: configstrp.ngrok.authtoken,
host_header:3000
},
(err, url) => {
if (err) {
} else {
}
}
);
}
Do not pass a subdomain if you do not have a custom domain
More convenient Swift 3 method:
let documentsUrl = FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first!
I know, its old a post to answer but like I came across searching for the same post, someone else might turn here as well
By adding : colour in ggplot function , I could achieve the lines with different colors related to the group present in the plot.
ggplot(data=Set6, aes(x=Semana, y=Net_Sales_in_pesos, group = Agencia_ID, colour = as.factor(Agencia_ID)))
and
geom_line()
If we split it up, the mess is equal to:
++[[]][+[]]
+
[+[]]
In JavaScript, it is true that +[] === 0
. +
converts something into a number, and in this case it will come down to +""
or 0
(see specification details below).
Therefore, we can simplify it (++
has precendence over +
):
++[[]][0]
+
[0]
Because [[]][0]
means: get the first element from [[]]
, it is true that:
[[]][0]
returns the inner array ([]
). Due to references it's wrong to say [[]][0] === []
, but let's call the inner array A
to avoid the wrong notation.
++
before its operand means “increment by one and return the incremented result”. So ++[[]][0]
is equivalent to Number(A) + 1
(or +A + 1
).
Again, we can simplify the mess into something more legible. Let's substitute []
back for A
:
(+[] + 1)
+
[0]
Before +[]
can coerce the array into the number 0
, it needs to be coerced into a string first, which is ""
, again. Finally, 1
is added, which results in 1
.
(+[] + 1) === (+"" + 1)
(+"" + 1) === (0 + 1)
(0 + 1) === 1
Let's simplify it even more:
1
+
[0]
Also, this is true in JavaScript: [0] == "0"
, because it's joining an array with one element. Joining will concatenate the elements separated by ,
. With one element, you can deduce that this logic will result in the first element itself.
In this case, +
sees two operands: a number and an array. It’s now trying to coerce the two into the same type. First, the array is coerced into the string "0"
, next, the number is coerced into a string ("1"
). Number +
String ===
String.
"1" + "0" === "10" // Yay!
Specification details for +[]
:
This is quite a maze, but to do +[]
, first it is being converted to a string because that's what +
says:
11.4.6 Unary + Operator
The unary + operator converts its operand to Number type.
The production UnaryExpression : + UnaryExpression is evaluated as follows:
Let expr be the result of evaluating UnaryExpression.
Return ToNumber(GetValue(expr)).
ToNumber()
says:
Object
Apply the following steps:
Let primValue be ToPrimitive(input argument, hint String).
Return ToString(primValue).
ToPrimitive()
says:
Object
Return a default value for the Object. The default value of an object is retrieved by calling the [[DefaultValue]] internal method of the object, passing the optional hint PreferredType. The behaviour of the [[DefaultValue]] internal method is defined by this specification for all native ECMAScript objects in 8.12.8.
[[DefaultValue]]
says:
8.12.8 [[DefaultValue]] (hint)
When the [[DefaultValue]] internal method of O is called with hint String, the following steps are taken:
Let toString be the result of calling the [[Get]] internal method of object O with argument "toString".
If IsCallable(toString) is true then,
a. Let str be the result of calling the [[Call]] internal method of toString, with O as the this value and an empty argument list.
b. If str is a primitive value, return str.
The .toString
of an array says:
15.4.4.2 Array.prototype.toString ( )
When the toString method is called, the following steps are taken:
Let array be the result of calling ToObject on the this value.
Let func be the result of calling the [[Get]] internal method of array with argument "join".
If IsCallable(func) is false, then let func be the standard built-in method Object.prototype.toString (15.2.4.2).
Return the result of calling the [[Call]] internal method of func providing array as the this value and an empty arguments list.
So +[]
comes down to +""
, because [].join() === ""
.
Again, the +
is defined as:
11.4.6 Unary + Operator
The unary + operator converts its operand to Number type.
The production UnaryExpression : + UnaryExpression is evaluated as follows:
Let expr be the result of evaluating UnaryExpression.
Return ToNumber(GetValue(expr)).
ToNumber
is defined for ""
as:
The MV of StringNumericLiteral ::: [empty] is 0.
So +"" === 0
, and thus +[] === 0
.
Google actually recommends this in regards to 'CSS Optimization'. They recommend in-lining critical above-fold styles and deferring the rest(css file).
Example:
<html>
<head>
<style>
.blue{color:blue;}
</style>
</head>
<body>
<div class="blue">
Hello, world!
</div>
</body>
</html>
<noscript><link rel="stylesheet" href="small.css"></noscript>
See: https://developers.google.com/speed/docs/insights/OptimizeCSSDelivery
As an aside to the solutions here, there are cleaner alternatives if you're using certain development servers.
With Heroku's Foreman, you can create per-project environment variables in a .env
file:
ADMIN_PASSOWRD="secret"
With Pow, you can use a .powenv
file:
export ADMIN_PASSOWRD="secret"
You are using a local path. Is that really what you want? If it is, you need to use the file:///
prefix:
file:///H:/media/css/static/img/sprites/buttons-v3-10.png
obviously, this will work only on your local computer.
Also, in many modern browsers, this works only if the page itself is also on a local file path. Addressing local files from remote (http://
, https://
) pages has been widely disabled due to security reasons.
I don't know if this will help anyone or not but as I was facing the same issue I thought of sharing how I got the solution.
You can use track by attribute in your ng-options
.
Assume that you have:
variants:[{'id':0, name:'set of 6 traits'}, {'id':1, name:'5 complete sets'}]
You can mention your ng-options
as:
ng-options="v.name for v in variants track by v.id"
Hope this helps someone in future.

One method would be to store the result of an inner merge form both dfs, then we can simply select the rows when one column's values are not in this common:
In [119]:
common = df1.merge(df2,on=['col1','col2'])
print(common)
df1[(~df1.col1.isin(common.col1))&(~df1.col2.isin(common.col2))]
col1 col2
0 1 10
1 2 11
2 3 12
Out[119]:
col1 col2
3 4 13
4 5 14
EDIT
Another method as you've found is to use isin
which will produce NaN
rows which you can drop:
In [138]:
df1[~df1.isin(df2)].dropna()
Out[138]:
col1 col2
3 4 13
4 5 14
However if df2 does not start rows in the same manner then this won't work:
df2 = pd.DataFrame(data = {'col1' : [2, 3,4], 'col2' : [11, 12,13]})
will produce the entire df:
In [140]:
df1[~df1.isin(df2)].dropna()
Out[140]:
col1 col2
0 1 10
1 2 11
2 3 12
3 4 13
4 5 14
They way I handle this problem is recursively. For example when reading data from the console:
Java.util.Scanner keyboard = new Java.util.Scanner(System.in);
public int GetMyInt(){
int ret;
System.out.print("Give me an Int: ");
try{
ret = Integer.parseInt(keyboard.NextLine());
}
catch(Exception e){
System.out.println("\nThere was an error try again.\n");
ret = GetMyInt();
}
return ret;
}
Drop a pidfile somewhere (e.g. /tmp). Then you can check to see if the process is running by checking to see if the PID in the file exists. Don't forget to delete the file when you shut down cleanly, and check for it when you start up.
#/usr/bin/env python
import os
import sys
pid = str(os.getpid())
pidfile = "/tmp/mydaemon.pid"
if os.path.isfile(pidfile):
print "%s already exists, exiting" % pidfile
sys.exit()
file(pidfile, 'w').write(pid)
try:
# Do some actual work here
finally:
os.unlink(pidfile)
Then you can check to see if the process is running by checking to see if the contents of /tmp/mydaemon.pid are an existing process. Monit (mentioned above) can do this for you, or you can write a simple shell script to check it for you using the return code from ps.
ps up `cat /tmp/mydaemon.pid ` >/dev/null && echo "Running" || echo "Not running"
For extra credit, you can use the atexit module to ensure that your program cleans up its pidfile under any circumstances (when killed, exceptions raised, etc.).
You want to use URI templates. Look carefully at the README of this project: URLEncoder.encode()
does NOT work for URIs.
Let us take your original URL:
http://site-test.test.com/Meetings/IC/DownloadDocument?meetingId=c21c905c-8359-4bd6-b864-844709e05754&itemId=a4b724d1-282e-4b36-9d16-d619a807ba67&file=\s604132shvw140\Test-Documents\c21c905c-8359-4bd6-b864-844709e05754_attachments\7e89c3cb-ce53-4a04-a9ee-1a584e157987\myDoc.pdf
and convert it to a URI template with two variables (on multiple lines for clarity):
http://site-test.test.com/Meetings/IC/DownloadDocument
?meetingId={meetingID}&itemId={itemID}&file={file}
Now let us build a variable map with these three variables using the library mentioned in the link:
final VariableMap = VariableMap.newBuilder()
.addScalarValue("meetingID", "c21c905c-8359-4bd6-b864-844709e05754")
.addScalarValue("itemID", "a4b724d1-282e-4b36-9d16-d619a807ba67e")
.addScalarValue("file", "\\\\s604132shvw140\\Test-Documents"
+ "\\c21c905c-8359-4bd6-b864-844709e05754_attachments"
+ "\\7e89c3cb-ce53-4a04-a9ee-1a584e157987\\myDoc.pdf")
.build();
final URITemplate template
= new URITemplate("http://site-test.test.com/Meetings/IC/DownloadDocument"
+ "meetingId={meetingID}&itemId={itemID}&file={file}");
// Generate URL as a String
final String theURL = template.expand(vars);
This is GUARANTEED to return a fully functional URL!
No need to use str.replace
or string.replace
here, just convert that string to a raw string:
>>> strs = r"C:\Users\Josh\Desktop\20130216"
^
|
notice the 'r'
Below is the repr
version of the above string, that's why you're seeing \\
here.
But, in fact the actual string contains just '\'
not \\
.
>>> strs
'C:\\Users\\Josh\\Desktop\\20130216'
>>> s = r"f\o"
>>> s #repr representation
'f\\o'
>>> len(s) #length is 3, as there's only one `'\'`
3
But when you're going to print this string you'll not get '\\'
in the output.
>>> print strs
C:\Users\Josh\Desktop\20130216
If you want the string to show '\\'
during print
then use str.replace
:
>>> new_strs = strs.replace('\\','\\\\')
>>> print new_strs
C:\\Users\\Josh\\Desktop\\20130216
repr
version will now show \\\\
:
>>> new_strs
'C:\\\\Users\\\\Josh\\\\Desktop\\\\20130216'
You only need to check odd divisors up to the square root of the number. In other words your inner loop needs to start:
for (int j = 3; j <= Math.Sqrt(i); j+=2) { ... }
You can also break out of the function as soon as you find the number is not prime, you don't need to check any more divisors (I see you're already doing that!).
This will only work if num is bigger than two.
No Sqrt
You can avoid the Sqrt altogether by keeping a running sum. For example:
int square_sum=1;
for (int j=3; square_sum<i; square_sum+=4*(j++-1)) {...}
This is because the sum of numbers 1+(3+5)+(7+9) will give you a sequence of odd squares (1,9,25 etc). And hence j
represents the square root of square_sum
. As long as square_sum
is less than i
then j
is less than the square root.
Method1: ADD_MONTHS
ADD_MONTHS(SYSDATE, -6)
Method 2: Interval
SYSDATE - interval '6' month
Note:
if you want to do the operations from start of the current month always, TRUNC(SYSDATE,'MONTH')
would give that. And it expects a Date
datatype as input.

Your question is based on assumption that the code which may throw NullPointerException
is worse than the code which may not. This assumption is wrong. If you expect that your foobar
is never null due to the program logic, it's much better to use Optional.of(foobar)
as you will see a NullPointerException
which will indicate that your program has a bug. If you use Optional.ofNullable(foobar)
and the foobar
happens to be null
due to the bug, then your program will silently continue working incorrectly, which may be a bigger disaster. This way an error may occur much later and it would be much harder to understand at which point it went wrong.
Suppose you want to insert a particular line of text (not an empty line):
@echo off
FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C
set /a totallines+=1
@echo off
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
SETLOCAL EnableDelayedExpansion
SET /p L=
IF %%i==%insertat% ECHO(!TL!
ECHO(!L!
ENDLOCAL
)
) >%tempfile%
COPY /Y %tempfile% %origfile% >NUL
DEL %tempfile%
You could use a pseudo element for this, and have your image on a hover:

Ideally you would put that in a directive, but you can also just put it in the controller. http://jsfiddle.net/tnq86/15/
angular.module('App', [])
.controller('AppCtrl', function ($scope) {
$scope.model = 0;
$scope.initSlider = function () {
$(function () {
// wait till load event fires so all resources are available
$scope.$slider = $('#slider').slider({
slide: $scope.onSlide
});
});
$scope.onSlide = function (e, ui) {
$scope.model = ui.value;
$scope.$digest();
};
};
$scope.initSlider();
});
The directive approach:
HTML
<div slider></div>
JS
angular.module('App', [])
.directive('slider', function (DataModel) {
return {
restrict: 'A',
scope: true,
controller: function ($scope, $element, $attrs) {
$scope.onSlide = function (e, ui) {
$scope.model = ui.value;
// or set it on the model
// DataModel.model = ui.value;
// add to angular digest cycle
$scope.$digest();
};
},
link: function (scope, el, attrs) {
var options = {
slide: scope.onSlide
};
// set up slider on load
angular.element(document).ready(function () {
scope.$slider = $(el).slider(options);
});
}
}
});
I would also recommend checking out Angular Bootstrap's source code: https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js
You can also use a factory to create the directive. This gives you ultimate flexibility to integrate services around it and whatever dependencies you need.
Have you tried setting the spacing to zero?
/*alternating row*/
table, tr, td, th {margin:0;border:0;padding:0;spacing:0;}
tr.rowhighlight {background-color:#f0f8ff;margin:0;border:0;padding:0;spacing:0;}
What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm
-vs-fcgi
but more to the implementation of your httpd
).
For example, I had a quad-core machine running lighttpd
+ fcgi
humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd
every 30 minutes to keep the website up.
I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.
Is this due to php-fpm
being better than fcgi
? Not entirely, but how you hook into php-fpm
seems to be a whole heckuva lot more efficient than how you serve via fcgi
.
TLDR? Try: file = open(filename, encoding='cp437)
Why? When one use:
file = open(filename)
text = file.read()
Python assumes the file uses the same codepage as current environment (cp1252 in case of the opening post) and tries to decode it to its own default UTF-8. If the file contains characters of values not defined in this codepage (like 0x90) we get UnicodeDecodeError. Sometimes we don't know the encoding of the file, sometimes the file's encoding may be unhandled by Python (like e.g. cp790), sometimes the file can contain mixed encodings.
If such characters are unneeded, one may decide to replace them by question marks, with:
file = open(filename, errors='replace')
Another workaround is to use:
file = open(filename, errors='ignore')
The characters are then left intact, but other errors will be masked too.
Quite good solution is to specify the encoding, yet not any encoding (like cp1252), but the one which has ALL characters defined (like cp437):
file = open(filename, encoding='cp437')
Codepage 437 is the original DOS encoding. All codes are defined, so there are no errors while reading the file, no errors are masked out, the characters are preserved (not quite left intact but still distinguishable).
Send XML requests with the raw
data type, then set the Content-Type to text/xml
.
After creating a request, use the dropdown to change the request type to POST.
Open the Body tab and check the data type for raw.
Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)
Enter your raw XML data into the input field below
Click Send to submit your XML Request to the specified server.
I stopped the rails server, ran rake db:migrate
and started my rails s
.
You can use SimpleDateFormat
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date d = sdf.parse("21/12/2012");
But I don't know whether it should be considered more right than to use Calendar ...
float: right
to.. float the second column to the.. right.overflow: hidden
to clear the floats so that the background color I just put in will be visible.#wrapper{
background:#000;
overflow: hidden
}
#c1 {
float:left;
background:red;
}
#c2 {
background:green;
float: right
}
Following steps helped me solve the issue.
In GitHub Wiki markdown I used hash marks (#) followed by two spaces to make the line break larger. It doesn't actually give you multiple line breaks but it made one large line break and served me well for my needs.
Instead of:
text
(space)(space)
more text
I did:
text
(hash mark)(space)(space)
more text
You could always do it recursively like so:
void freeList(struct node* currentNode)
{
if(currentNode->next) freeList(currentNode->next);
free(currentNode);
}
new
isn't required and should be avoidedvar str = new String('asd'); // type: object
var str = String('asd'); // type: string
var num = new Number(12); // type: object
var num = Number(12); // type: number
new
is required, otherwise you'll get an errornew Date().getFullYear(); // correct, returns the current year, i.e. 2010
Date().getFullYear(); // invalid, returns an error
Even though answers to this question are long overdue, but I'm still posting a nice solution that I came with some time ago and makes it really simple to send complex JSON to Asp.net MVC controller actions so they are model bound to whatever strong type parameters.
This plugin supports dates just as well, so they get converted to their DateTime
counterpart without a problem.
You can find all the details in my blog post where I examine the problem and provide code necessary to accomplish this.
All you have to do is to use this plugin on the client side. An Ajax request would look like this:
$.ajax({
type: "POST",
url: "SomeURL",
data: $.toDictionary(yourComplexJSONobject),
success: function() { ... },
error: function() { ... }
});
But this is just part of the whole problem. Now we are able to post complex JSON back to server, but since it will be model bound to a complex type that may have validation attributes on properties things may fail at that point. I've got a solution for it as well. My solution takes advantage of jQuery Ajax functionality where results can be successful or erroneous (just as shown in the upper code). So when validation would fail, error
function would get called as it's supposed to be.
The most trivial way to download a binary file from an FTP server using .NET framework is using WebClient.DownloadFile
:
WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
client.DownloadFile(
"ftp://ftp.example.com/remote/path/file.zip", @"C:\local\path\file.zip");
Use FtpWebRequest
, only if you need a greater control, that WebClient
does not offer (like TLS/SSL encryption, progress monitoring, ascii/text transfer mode, resuming transfers, etc). Easy way is to just copy an FTP response stream to FileStream
using Stream.CopyTo
:
FtpWebRequest request =
(FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
ftpStream.CopyTo(fileStream);
}
If you need to monitor a download progress, you have to copy the contents by chunks yourself:
FtpWebRequest request =
(FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
byte[] buffer = new byte[10240];
int read;
while ((read = ftpStream.Read(buffer, 0, buffer.Length)) > 0)
{
fileStream.Write(buffer, 0, read);
Console.WriteLine("Downloaded {0} bytes", fileStream.Position);
}
}
For GUI progress (WinForms ProgressBar
), see:
FtpWebRequest FTP download with ProgressBar
If you want to download all files from a remote folder, see
C# Download all files and subdirectories through FTP.
try this too
pd.set_option("max_columns", None) # show all cols
pd.set_option('max_colwidth', None) # show full width of showing cols
pd.set_option("expand_frame_repr", False) # print cols side by side as it's supposed to be
I'm not sure whether you think about:
select * from friend f
where not exists (
select 1 from likes l where f.id1 = l.id and f.id2 = l.id2
)
it works only if id1 is related with id1 and id2 with id2 not both.
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
If you have a <script>
tag anywhere on your page (even in the HTML, even if it is an empty tag with a src
), then a transition
must be activated by some event (it won't fire automatically when the page loads).
I'd recommend pygit2 - it uses the excellent libgit2 bindings
This will allow file names to have spaces (reproducible example).
# Select files of interest, here, only text files for ex.
find -type f -exec file {} \; > findresult.txt
grep ": ASCII text$" findresult.txt > textfiles.txt
# leave only the path to the file removing suffix and prefix
sed -i -e 's/:.*$//' textfiles.txt
sed -i -e 's/\.\///' textfiles.txt
#write a script that deletes the files in textfiles.txt
IFS_backup=$IFS
IFS=$(echo "\n\b")
for f in $(cat textfiles.txt);
do
rm "$f";
done
IFS=$IFS_backup
# save script as "some.sh" and run: sh some.sh
Most of the time req.body is undefined due to missing JSON parser
const express = require('express');
app.use(express.json());
could be missing for the body-parser
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({extended: true}));
and sometimes it's undefined due to cros origin so add them
const cors = require('cors');
app.use(cors())
To change database owner:
ALTER AUTHORIZATION ON DATABASE::YourDatabaseName TO sa
As of SQL Server 2014 you can still use sp_changedbowner
as well, even though Microsoft promised to remove it in the "future" version after SQL Server 2012. They removed it from SQL Server 2014 BOL though.
In my case the excel was frozen when using the formula of
B2=INDEX($A$2:$A$20, MATCH(0, COUNTIF($B$1:B1, $A$2:$A$20), 0))
because there was many rows (10000). So I did in another way which I show below.
I have copied my original list to a second column and then with the function of Excel "remove duplicates" I could find the list of unique values.
Copied from Microsoft Office Website:
Select all the rows, including the column headers, in the list
you want to filter.
Click the top left cell of the range, and then drag to the bottom right cell.
On the Data menu, point to Filter, and then click Advanced Filter. In the Advanced Filter dialog box, click Filter the list, in place. Select the Unique records only check box, and then click OK.
The filtered list is displayed and the duplicate rows are hidden.
On the Edit menu, click Office Clipboard.
The Clipboard task pane is displayed.
Make sure the filtered list is still selected, and then click Copy Copy button.
The filtered list is highlighted with bounding outlines and the selection appears as an > > item at the top of the Clipboard.
On the Data menu, point to Filter, and then click Show All.
The original list is re-displayed.
Press the DELETE key.
The original list is deleted.
In the Clipboard, click on the filtered list item.
The filtered list appears in the same location as the original list.

Noone cand read the file except for those who have access to the file. You must make the code readable (but not writable) by the web server. If the php code handler is running properly you can't read it by requesting by name from the web server.
If someone compromises your server you are at risk. Ensure that the web server can only write to locations it absolutely needs to. There are a few locations under /var which should be properly configured by your distribution. They should not be accessible over the web. /var/www should not be writable, but may contain subdirectories written to by the web server for dynamic content. Code handlers should be disabled for these.
Ensure you don't do anything in your php code which can lead to code injection. The other risk is directory traversal using paths containing .. or begining with /. Apache should already be patched to prevent this when it is handling paths. However, when it runs code, including php, it does not control the paths. Avoid anything that allows the web client to pass a file path.

In C# running this
UnicodeEncoding encoding = new UnicodeEncoding();
byte[] bytes = encoding.GetBytes("Hello");
Will create an array with

For a character which the code is greater than 255 it will look like this
If you want a very similar behavior in JavaScript you can do this (v2 is a bit more robust solution, while the original version will only work for 0x00 ~ 0xff)
var str = "Hello?";_x000D_
var bytes = []; // char codes_x000D_
var bytesv2 = []; // char codes_x000D_

Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.
These are much much better references than w3schools (the most awful web reference ever made):
Examples derived from these references:
// sets the cookie cookie1
document.cookie = 'cookie1=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'
// sets the cookie cookie2 (cookie1 is *not* overwritten)
document.cookie = 'cookie2=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'
// remove cookie2
document.cookie = 'cookie2=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/'
The Mozilla reference even has a nice cookie library you can use.
I couldn't find any solution to this problem, until I found out the files didn't exist! This took me a long time to figure out, because the Solution Explorer shows the files!

In new version of Laravel you can use "Service Injection".
https://laravel.com/docs/5.8/blade#service-injection
/resources/views/main.blade.php
@inject('project', 'App\Project')
<h1>{{ $project->get_title() }}</h1>
Echo UTF-8 BOM before outputing CSV data. This fixes all character issues in Windows but doesnt work for Mac.
echo "\xEF\xBB\xBF";
It works for me because I need to generate a file which will be used on Windows PCs only.
you need to add Content-Length: 0
in your request header.
a very descriptive example of how to test is given here
To communicate a child component with another child component I've made a method in parent which calls a method in a child with:
this.$refs.childMethod()
And from the another child I've called the root method:
this.$root.theRootMethod()
It worked for me.

If you're using JAVA 8 or more than use stream functionality following way,
Stream.generate(() -> (new Random()).nextInt(10000)).distinct().limit(10000);
I use this one:
select max(table_catalog) as x from information_schema.tables
to check connection and ability to run queries (with 1 row as result) for postgreSQL, MySQL and MSSQL.
int length;
Scanner input = new Scanner(System.in);
System.out.println("How many numbers you wanna enter?");
length = input.nextInt();
System.out.println("Enter " + length + " numbers, one by one...");
int[] arr = new int[length];
for (int i = 0; i < arr.length; i++) {
System.out.println("Enter the number " + (i + 1) + ": ");
//Below is the way to collect the element from the user
arr[i] = input.nextInt();
// auto generate the elements
//arr[i] = (int)(Math.random()*100);
}
input.close();
System.out.println(Arrays.toString(arr));

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus "collision"). Finding a collision using a birthday attack takes O(2^(n/2)) time, where n is the output length of the hash function in bits.
SHA-2 has an output size of 512 bits, so finding a collision would take O(2^256) time. Given there are no clever attacks on the algorithm itself (currently none are known for the SHA-2 hash family) this is what it takes to break the algorithm.
To get a feeling for what 2^256 actually means: currently it is believed that the number of atoms in the (entire!!!) universe is roughly 10^80 which is roughly 2^266. Assuming 32 byte input (which is reasonable for your case - 20 bytes salt + 12 bytes password) my machine takes ~0,22s (~2^-2s) for 65536 (=2^16) computations. So 2^256 computations would be done in 2^240 * 2^16 computations which would take
2^240 * 2^-2 = 2^238 ~ 10^72s ~ 3,17 * 10^64 years
Even calling this millions of years is ridiculous. And it doesn't get much better with the fastest hardware on the planet computing thousands of hashes in parallel. No human technology will be able to crunch this number into something acceptable.
So forget brute-forcing SHA-256 here. Your next question was about dictionary words. To retrieve such weak passwords rainbow tables were used traditionally. A rainbow table is generally just a table of precomputed hash values, the idea is if you were able to precompute and store every possible hash along with its input, then it would take you O(1) to look up a given hash and retrieve a valid preimage for it. Of course this is not possible in practice since there's no storage device that could store such enormous amounts of data. This dilemma is known as memory-time tradeoff. As you are only able to store so many values typical rainbow tables include some form of hash chaining with intermediary reduction functions (this is explained in detail in the Wikipedia article) to save on space by giving up a bit of savings in time.
Salts were a countermeasure to make such rainbow tables infeasible. To discourage attackers from precomputing a table for a specific salt it is recommended to apply per-user salt values. However, since users do not use secure, completely random passwords, it is still surprising how successful you can get if the salt is known and you just iterate over a large dictionary of common passwords in a simple trial and error scheme. The relationship between natural language and randomness is expressed as entropy. Typical password choices are generally of low entropy, whereas completely random values would contain a maximum of entropy.
The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords. If you google for them, you will end up finding torrent links for such password databases, often in the gigabyte size category. Being successful with such a tool is usually in the range of minutes to days if the attacker is not restricted in any way.
That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5 and you should enforce a waiting period for a given user before they may retry entering their password. A good scheme is to start with 0.5s and then doubling that time for each failed attempt. In most cases users don't notice this and don't fail much more often than three times on average. But it will significantly slow down any malicious outsider trying to attack your application.
In may case I had a global variable in one of my .h
files that was causing the problem, and I solved it by adding extern
in front of it.
If you are using .Net client then you may not have set
//This says how many outgoing connection you can make to a single endpoint. Default Value is 2
System.Net.ServicePointManager.DefaultConnectionLimit = 200;
here is the original question and answer WCF Service Throttling
Update:
This config goes in .Net client application may be on start up or whenever but before starting your tests.
Moreover you can have it in app.config file as well like following
<system.net>
<connectionManagement>
<add maxconnection = "200" address ="*" />
</connectionManagement>
</system.net>
I would use XMLHTTP request to retrieve page content as much faster. Then it is easy enough to use querySelectorAll to apply a CSS class selector to grab by class name. Then you access the child elements by tag name and index.

You should be able to read the GUID attribute of the assembly via reflection. This will get the GUID for the current assembly
Assembly asm = Assembly.GetExecutingAssembly();
var attribs = (asm.GetCustomAttributes(typeof(GuidAttribute), true));
Console.WriteLine((attribs[0] as GuidAttribute).Value);
You can replace the GuidAttribute with other attributes as well, if you want to read things like AssemblyTitle, AssemblyVersion, etc.
You can also load another assembly (Assembly.LoadFrom and all) instead of getting the current assembly - if you need to read these attributes of external assemblies (for example, when loading a plugin).
It may be caused by IE's box model bug. To fix this, you can use the Box Model Hack.
You can simply figure out :
git log --cherry master...experimental
--cherry
option is a synonym for --right-only --cherry-mark --no-merges
git-log man page said
it's useful to limit the output to the commits on our side and mark those that have been applied to the other side of a forked history with git log --cherry upstream...mybranch, similar to git cherry upstream mybranch.
FYI. --cherry-pick
omits equivalent commits but --cherry-marks
doesn't. It's useful to find rebase and force updated changes between upstream and co-working public branch
Based on Crescent Fresh answer
if you want to detect links with http:// OR without http:// and by www. you can use the following
function urlify(text) {
var urlRegex = /(((https?:\/\/)|(www\.))[^\s]+)/g;
//var urlRegex = /(https?:\/\/[^\s]+)/g;
return text.replace(urlRegex, function(url,b,c) {
var url2 = (c == 'www.') ? 'http://' +url : url;
return '<a href="' +url2+ '" target="_blank">' + url + '</a>';
})
}
The get_ddl procedure for a PACKAGE will return both spec AND body, so it will be better to change the query on the all_objects so the package bodies are not returned on the select.
So far I changed the query to this:
SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type, ' ', '_'), object_name, owner)
FROM all_OBJECTS
WHERE (OWNER = 'OWNER1')
and object_type not like '%PARTITION'
and object_type not like '%BODY'
order by object_type, object_name;
Although other changes might be needed depending on the object types you are getting...
This will capture requests for files like version
,
release
, and README.md
, etc. which should be
treated either as endpoints, if defined (as in the
case of /release), or as "not found."
Lots of great answers here but I feel like I can add my own because of simplicity, performance (comparing to resource-related solutions) cross platform (works with Net Core too) and avoidance of any 3rd party tool. Just add this msbuild target to the csproj.
<Target Name="Date" BeforeTargets="CoreCompile">
<WriteLinesToFile File="$(IntermediateOutputPath)gen.cs" Lines="static partial class Builtin { public static long CompileTime = $([System.DateTime]::UtcNow.Ticks) %3B }" Overwrite="true" />
<ItemGroup>
<Compile Include="$(IntermediateOutputPath)gen.cs" />
</ItemGroup>
</Target>
and now you have Builtin.CompileTime
or new DateTime(Builtin.CompileTime, DateTimeKind.Utc)
if you need it that way.
ReSharper is not gonna like it. You can ignore him or add a partial class to the project too but it works anyway.
Hi, this will throw an error:
foreach ($product->sku as $sku){
// Code Here
}
because you cannot loop a model with a specific column ($product->sku) from the table.
So you must loop on the whole model:
foreach ($product as $p) {
// code
}
Inside the loop you can retrieve whatever column you want just adding "->[column_name]"
foreach ($product as $p) {
echo $p->sku;
}
Have a great day
Simple css:
input[value]:not([value=""])
This code is going to apply the given css on page load if the input is filled up.
Instead of using np.argsort
you could use np.argpartition
- if you only need the indices of the lowest/highest n elements.
That doesn't require to sort the whole array but just the part that you need but note that the "order inside your partition" is undefined, so while it gives the correct indices they might not be correctly ordered:
>>> avgDists = [1, 8, 6, 9, 4]
>>> np.array(avgDists).argpartition(2)[:2] # indices of lowest 2 items
array([0, 4], dtype=int64)
>>> np.array(avgDists).argpartition(-2)[-2:] # indices of highest 2 items
array([1, 3], dtype=int64)

I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.
I had <meta http-equiv="x-ua-compatible" content="ie=edge">
on the page.
In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.
Since Java 5, you can use java.util.concurrent.TimeUnit
to avoid the use of Magic Numbers like 1000 and 60 in your code.
By the way, you should take care to leap seconds in your computation: the last minute of a year may have an additional leap second so it indeed lasts 61 seconds instead of expected 60 seconds. The ISO specification even plan for possibly 61 seconds. You can find detail in java.util.Date
javadoc.

ControlToValidate="txtDatecompleted"
ErrorMessage="Please enter a valid date.">

UPDATE table SET field = replace(field, text_needs_to_be_replaced, text_required);
Like for example, if I want to replace all occurrences of John by Mark I will use below,
UPDATE student SET student_name = replace(student_name, 'John', 'Mark');
var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'
or, on mozilla:
document.body.onselectstart = function() { return false; } // Or any html object
On IE,
document.body.onmousedown = function() { return false; } // valid for any html object as well
Just for punctuality purpose and extend a bit Tim answer.
From official documentation:
The app returned by express() is in fact a JavaScript Function, DESIGNED TO BE PASSED to Node’s HTTP servers as a callback to handle requests.
This makes it easy to provide both HTTP and HTTPS versions of your app with the same code base, as the app does not inherit from these (it is simply a callback):
http.createServer(app).listen(80);
https.createServer(options, app).listen(443);
The app.listen() method returns an http.Server object and (for HTTP) is a convenience method for the following:
app.listen = function() {
var server = http.createServer(this);
return server.listen.apply(server, arguments);
};
Swift 4:
DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(100)) {
// Code
}
For the time .seconds(Int)
, .microseconds(Int)
and .nanoseconds(Int)
may also be used.
as a possible solution: Add some extra more content to the title. Overwrite this css style:
.fc-day-grid-event .fc-content {
white-space: normal;
}
Here's an example that puts the Now()
value in column A.
Sub move()
Dim i As Integer
Dim sh1 As Worksheet
Dim sh2 As Worksheet
Dim nextRow As Long
Dim copyRange As Range
Dim destRange As Range
Application.ScreenUpdating = False
Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
Set copyRange = sh1.Range("A1:A5")
i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4
Set destRange = sh2.Range("B" & i)
destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")
copyRange.Clear
Application.ScreenUpdating = True
End Sub
There are better ways of getting the last row in column B than using a While
loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3
have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)

You're trying to access a 3 dimensional array with 4 de-references
You only need 3 loops instead of 4, or int myArray[10][10][10][10];
I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {}
statements.
Each time the switch function is the same but the command we supply changes.
do.this <- "T1"
switch(do.this,
T1={X <- t(mtcars)
colSums(mtcars)%*%X
},
T2={X <- colMeans(mtcars)
outer(X, X)
},
stop("Enter something that switches me!")
)

OPTION 1: if you want to make a common utility function then you can use this
export function getCurrentDate(separator=''){
let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();
return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}
and use it by just importing it as
import {getCurrentDate} from './utils'
console.log(getCurrentDate())
OPTION 2: or define and use in a class directly
getCurrentDate(separator=''){
let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();
return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

For HSQLDB, The following worked for me:
DatabaseManager.threadedDBM();
And this brought up the GUI with my tables and data once I pointed it to the right named in-mem database.
It is basically the equivalent of newing up a DatabaseManager
(the non Swing variety), which prompts for connection details, and is set to --noexit
)
I also tried the Swing version, but it only had a main
, and I was unsure of the arguments to pass. If anyone knows, please post here.
Just because I searched for hours for the right database name: The name of the database is the name of your datasource. So try with URL jdbc:hsqldb:mem:dataSource if you have a data source bean with id=dataSource. If this does not work, try testdb which is the default.
I wasn't able to do that with any swal(sweatAlert) default callback function, so I forced with jquery, got the Ok button class inspecting the element in chrome an made something like this:
<script>
sweetAlert({
title:'Warning!',
text: 'Invalid user or password!',
type:'warning'
},function(isConfirm){
alert('ok');
});
$('.swal2-confirm').click(function(){
window.location.href = 'index.php';
});
</script>
The 'Ok' alert in function(isConfirm) was just a test to see if it would get into this function, if so I should be able to redirect from there, but I wasn't...
So I used jQuery to determine if the button "OK" of swal was clicked by getting it class: ".swal2-confirm' then I could redirect with success...
Hope this helps you all !
PS: I am using php echo to run the script, I din't have to leave php to run it, just use single quotes and you're done !

we can do like this:
in application.yml:
spring:
profiles:
active: test //modify here to switch between environments
include: application-${spring.profiles.active}.yml
in application-test.yml:
server:
port: 5000
and in application-local.yml:
server:
address: 0.0.0.0
port: 8080
then spring boot will start our app as we wish to.
It looks as though the horizontal axis (Category Group) labels have very long values - there may not be room to display them all. I suggest changing the labels to have shorter values.
You can set the sort order for the Category Groups in the Category Group Properties - Sorting section - this may have been previously set; if not, I suggest using this to sort as desired.
The answer above is correct. Please be sure that you have a string data in base64 in the data variable without any prefix or stuff like that just raw data.
Here's what I did on the server side (asp.net mvc core):
string path = Path.Combine(folder, fileName);
Byte[] bytes = System.IO.File.ReadAllBytes(path);
string base64 = Convert.ToBase64String(bytes);
On the client side, I did the following code:
const xhr = new XMLHttpRequest();
xhr.open("GET", url);
xhr.setRequestHeader("Content-Type", "text/plain");
xhr.onload = () => {
var bin = atob(xhr.response);
var ab = s2ab(bin); // from example above
var blob = new Blob([ab], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' });
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = 'demo.xlsx';
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
};
xhr.send();
And it works perfectly for me.
Try this :abc > myFile.txt
First, it will create a file with name myFile.txt
in present working directory (in command prompt). Then it will run the command abc
which is not a valid command. In this way, you have gotten a new empty file with the name myFile.txt
.
There is obviously another process listening on the port. You might find out that process by using the following command:
$ lsof -i :8000
or change your tornado app's port. tornado's error info not Explicitly on this.
In Servlet technology if you want to pass any input to a particular servlet then you need to pass in init param like below code.
<servlet>
<servlet-name>DBController</servlet-name>
<servlet-class>com.test.controller.DBController</servlet-class>
<init-param>
<param-name>username</param-name>
<param-value>John</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DBController</servlet-name>
<url-pattern>/DBController</url-pattern>
</servlet-mapping>
If you want to pass some in put that is common for all servlets then that time you need to configure context param. Example
<context-param>
<param-name>email</param-name>
<param-value>[email protected]</param-value>
</context-param>
SO exactly like this when ever we are working with Spring MVC we need to provide some information to Predefined servlet provided by Spring that is DispatcherServlet through init param. So the configuration is as fallows, here we are providing the spring-servlet.xml as init parameter to DispatcherServlet.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>Spring MVC App</display-name>
<servlet>
<servlet-name>SpringController</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringController</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
</web-app>
Again we need some context param. That is applicable for whole application. So we can provide the root context that is applicationcontext.xml The configuration is like this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationcontext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>SpringController</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringController</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
You can use tree to generate something very similar to your example. Once you have the output, you can wrap it in a <pre>
tag to preserve the plain text formatting.
So I'm not entirely sure why this works, but it saves an image with my plot:
dtf = pd.DataFrame.from_records(d,columns=h)
dtf2.plot()
fig = plt.gcf()
fig.savefig('output.png')
I'm guessing that the last snippet from my original post saved blank because the figure was never getting the axes generated by pandas. With the above code, the figure object is returned from some magic global state by the gcf() call (get current figure), which automagically bakes in axes plotted in the line above.
Dmytro did a good job, but here is a more concise version.
class Program
{
static void Main(string[] args)
{
LinkedList linkedList = new LinkedList(1);
linkedList.Add(2);
linkedList.Add(3);
linkedList.Add(4);
linkedList.AddFirst(0);
linkedList.Print();
}
}
public class Node
{
public Node(Node next, Object value)
{
this.next = next;
this.value = value;
}
public Node next;
public Object value;
}
public class LinkedList
{
public Node head;
public LinkedList(Object initial)
{
head = new Node(null, initial);
}
public void AddFirst(Object value)
{
head = new Node(head, value);
}
public void Add(Object value)
{
Node current = head;
while (current.next != null)
{
current = current.next;
}
current.next = new Node(null, value);
}
public void Print()
{
Node current = head;
while (current != null)
{
Console.WriteLine(current.value);
current = current.next;
}
}
}
Just check the error in log cat.
You get the log cat option from in eclipse:
window->show view->others->Android->Logcat
Log cat contains error.
Other wise you can also check the error by executing an application in debug mode. Firstly set breakpoint after that by doing:
right click on project->debug as->Android application
As described in this link http://droidista.blogspot.in/2012/04/adding-float-value-to-your-resources.html
Declare in dimen.xml
<item name="my_float_value" type="dimen" format="float">9.52</item>
Referencing from xml
@dimen/my_float_value
Referencing from java
TypedValue typedValue = new TypedValue();
getResources().getValue(R.dimen.my_float_value, typedValue, true);
float myFloatValue = typedValue.getFloat();
Similar to Etienne's solution, a simple table formats nicely:
| | |
|-|-|
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
Another alternative (which comes with more emphasis), is to make the content the header of a body-less table:
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
|-|-|
Finally, you can include a horizontal line (thematic break) to create a closed box (although the line style is a little different than the header line in the table):
| | |
|-|-|
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
---
Note the empty line after the text.
Try this Code
List itemStates = new List();
for (int i = 0; i < 10; i++)
{
itemStates.Add(new ItemState { Id = i.ToString() });
dataGridView1.DataSource = itemStates;
dataGridView1.DataBind();
System.Threading.Thread.Sleep(500);
}

Also, I've changed two ^=

And note the :checked
selector. See http://api.jquery.com/checked-selector/
function createcodes() {
//run through each row
$('.authors-list tr').each(function (i, row) {

var $row = $(row),
$family = $row.find('input[name*="family"]'),
$grade = $row.find('input[name*="grade"]'),
$checkedBoxes = $row.find('input:checked');
$checkedBoxes.each(function (i, checkbox) {
// assuming you layout the elements this way,
// we'll take advantage of .next()
var $checkbox = $(checkbox),
$line = $checkbox.next(),
$size = $line.next();
$line.val(

For PHP 5.3 this should work. You may need to fiddle with passing $dateInfo['is_dst'], wasn't working for me anyhow.
$date = '05/Feb/2010:14:00:01';
$dateInfo = date_parse_from_format('d/M/Y:H:i:s', $date);
$unixTimestamp = mktime(
$dateInfo['hour'], $dateInfo['minute'], $dateInfo['second'],
$dateInfo['month'], $dateInfo['day'], $dateInfo['year'],
$dateInfo['is_dst']
);
Versions prior, this should work.
$date = '05/Feb/2010:14:00:01';
$format = '@^(?P<day>\d{2})/(?P<month>[A-Z][a-z]{2})/(?P<year>\d{4}):(?P<hour>\d{2}):(?P<minute>\d{2}):(?P<second>\d{2})$@';
preg_match($format, $date, $dateInfo);
$unixTimestamp = mktime(
$dateInfo['hour'], $dateInfo['minute'], $dateInfo['second'],
date('n', strtotime($dateInfo['month'])), $dateInfo['day'], $dateInfo['year'],
date('I')
);
You may not like regular expressions. You could annotate it, of course, but not everyone likes that either. So, this is an alternative.
$day = $date[0].$date[1];
$month = date('n', strtotime($date[3].$date[4].$date[5]));
$year = $date[7].$date[8].$date[9].$date[10];
$hour = $date[12].$date[13];
$minute = $date[15].$date[16];
$second = $date[18].$date[19];
Or substr, or explode, whatever you wish to parse that string.
In general, these answer the question: How to change your user settings file? But the question I wanted answered was how to change my local maven repository location. The answer is that you have to edit settings.xml. If the file does not exist, you have to create it. You set or change the location of the file at Window > Preferences > Maven > User Settings. It's the User Settings entry at
It's the second file input; the first with information in it.
If it's not clear, [redacted]
should be replaced with the local file path to your .m2 folder.
If you click the "open file" link, it opens the settings.xml file for editing in Eclipse.
If you have no settings.xml file yet, the following will set the local repository to the Windows 10 default value for a user named mdfst13:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
https://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>C:\Users\mdfst13\.m2\repository</localRepository>
</settings>
You should set this to a value appropriate to your system. I haven't tested it, but I suspect that in Linux, the default value would be /home/mdfst13/.m2/repository
. And of course, you probably don't want to set it to the default value. If you are reading this, you probably want to set it to some other value. You could just delete it if you wanted the default.
Credit to this comment by @ejaenv for the name of the element in the settings file: <localRepository>
. See Maven — Settings Reference for more information.
Credit to @Ajinkya's answer for specifying the location of the User Settings value in Eclipse Photon.
If you already have a settings.xml file, you should merge this into your existing file. I.e. <settings
and <localRepository>
should only appear once in the file, and you probably want to retain any settings already there. Or to say that another way, edit any existing local repository entry if it exists or just add that line to the file if it doesn't.
I had to restart Eclipse for it to load data into the new repository. Neither "Update Settings" nor "Reindex" was sufficient.
How about this :
// Checks to see if the value passed is valid.
if (!TypeDescriptor.GetConverter(typeof(T)).IsValid(value))
{

Sometimes you really want to set the axes limits before you plot the data. In that case, you can set the "autoscaling" feature of the Axes
or AxesSubplot
object. The functions of interest are set_autoscale_on
, set_autoscalex_on
, and set_autoscaley_on
.
In your case, you want to freeze the y axis' limits, but allow the x axis to expand to accommodate your data. Therefore, you want to change the autoscaley_on
property to False
. Here is a modified version of the FFT subplot snippet from your code:
fft_axes = pylab.subplot(h,w,2)
pylab.title("FFT")
fft = scipy.fft(rawsignal)
pylab.ylim([0,1000])
fft_axes.set_autoscaley_on(False)
pylab.plot(abs(fft))
Foreword: Well, that escalated quickly. But decided to pull it through. May this answer be helpful to you and other readers.
While JSLint and JSHint are good tools to use, over the years I've come to appreciate what my friend @ugly_syntax calls:
smaller design space.
This is a general principle, much like a "zen monk", limiting the choices one has to make, one can be more productive and creative.
Therefore my current favourite zero-config JS code style:
UPDATE:
Flow has improved a lot. With it, you can add types to your JS with will help you prevent a lot of bugs. But it can also stay out of your way, for instance when interfacing untyped JS. Give it a try!
Add standard
as a dependency to you project
npm install --save standard
Then in package.json
, add the following test script:
"scripts": {
"test": "node_modules/.bin/standard && echo put further tests here"
},
For snazzier output while developing, npm install --global snazzy
and run it instead of npm test
.
My friend when mentioning design space referred to Elm and I encourage you to give that language a try.
Why? JS is in fact inspired by LISP, which is a special class of languages, which happens to be untyped. Language such as Elm or Purescript are typed functional programming languages.
Type restrict your freedom in order for the compiler to be able to check and guide you when you end up violation the language or your own program's rules; regardless of the size (LOC) of your program.
We recently had a junior colleague implement a reactive interface twice: once in Elm, once in React; have a look to get some idea of what I'm talking about.
(ps. note that the React code is not idiomatic and could be improved)
the reality is that JS is untyped. Who am I to suggest typed programming to you?
See, with JS we are in a different domain: freed from types, we can easily express things that are hard or impossible to give a proper type (which can certainly be an advantage).
But without types there is little to keep our programs in check, so we are forced to introduce tests and (to a lesser extend) code styles.
I recommend you look at LISP (e.g. ClojureScript) for inspiration and invest in testing your codes. Read The way of the substack to get an idea.
Peace.
Here is one possible way. Use the exists
function to check for something unique in your util.R
code.
For example:
if(!exists("foo", mode="function")) source("util.R")
(Edited to include mode="function"
, as Gavin Simpson pointed out)
as explained here
With help from numpy one can calculate for example a linear fitting.
# plot the data itself
pylab.plot(x,y,'o')
# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])
Since Java 11 you can do it even simpler:
import java.nio.file.Files;
Files.readString(Path path);
Files.readString?(Path path, Charset cs)

Ugliest interface possible, but does what you ask. Zero allocations.
http://zserge.com/jsmn.html Another zero-allocation approach.
The solutions posted above all do dynamic memory allocation, hence will be inevitably end up slower at some point, depending on the data structure - and will be dangerous to include in a heap constrained environment like an embedded system.
Benchmarks of vjson, rapidjson and sajson here : http://chadaustin.me/2013/01/json-parser-benchmarking/ if you are interested in that sort of thing.
And to answer your "writer" part of the question i doubt that you could beat an efficient
printf("{%s:%s}",name,value)
implementation with any library - assuming your printf/sprintf implementation itself is lightweight of course.
EDIT: actually let me take that back, RapidJson allows on-stack allocation only through its MemoryPoolAllocator and actually makes this a default for its GenericReader. I havent done the comparison but i would expect it to be more robust than anything else listed here. It also doesnt have any dependencies, and it doesnt throw exceptions which probably makes it ultimately suitable for embedded. Fully header based lib so, easy to include anywhere.
There is indeed a Groovier Way.
if(members){
//Some work
}
does everything if members
is a collection. Null check as well as empty check (Empty collections are coerced to false
). Hail Groovy Truth. :)
Since the extension will always be the string after a period in a complete/partial file name, just use the built in split function in js, and test the resultant extension for what you want it to do. If split returns only one piece / no pieces, it does not contain an extension.
To multiply a column of numbers with a constant(same number), I have done like this.
Let C2
to C12
be different numbers which need to be multiplied by a single number (constant). Then type the numbers from C2
to C12.
In D2
type 1 (unity) and in E2 type formula =PRODUCT(C2:C12,CONSTANT)
. SELECT RIGHT ICON TO APPLY. NOW DRAG E2
THROUGH E12
. YOU HAVE DONE IT.
C D E=PRODUCT(C2:C12,20)
25 1 500
30 600
35 700
40 800
45 900
50 1000
55 1100
60 1200
65 1300
70 1400
75 1500
Further to @pmg's answer, note that you can do both operations in one statement:
char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;
This will likely work as expected but behavior is undefined in C standard.
According to Microsoft documentation, should NEVER use async void
Do not do this: The following example uses
async void
which makes the HTTP request complete when the first await is reached:
Which is ALWAYS a bad practice in ASP.NET Core apps.
Accesses the HttpResponse after the HTTP request is complete.
Crashes the process.
Select e.lastname as employee ,m.lastname as manager
from employees e,employees m
where e.managerid=m.employyid(+)
This line:
public object Hours { get; set; }}
Your have a redundand }
at the end
try this approach if you know your object client name ( it is not important that it is Button or TextBox )
$('#ButtonName').removeAttr('onclick');
$('#ButtonName').attr('onClick', 'FunctionName(this);');
try this ones if you want add onClick event to a server object with JQuery
$('#' + '<%= ButtonName.ClientID %>').removeAttr('onclick');
$('#' + '<%= ButtonName.ClientID %>').attr('onClick', 'FunctionName(this);');
GPS, the Global Positioning System run by the United States Military, is free for civilian use, though the reality is that we're paying for it with tax dollars.
However, GPS on cell phones is a bit more murky. In general, it won't cost you anything to turn on the GPS in your cell phone, but when you get a location it usually involves the cell phone company in order to get it quickly with little signal, as well as get a location when the satellites aren't visible (since the gov't requires a fix even if the satellites aren't visible for emergency 911 purposes). It uses up some cellular bandwidth. This also means that for phones without a regular GPS receiver, you cannot use the GPS at all if you don't have cell phone service.
For this reason most cell phone companies have the GPS in the phone turned off except for emergency calls and for services they sell you (such as directions).
This particular kind of GPS is called assisted GPS (AGPS), and there are several levels of assistance used.
A normal GPS receiver listens to a particular frequency for radio signals. Satellites send time coded messages at this frequency. Each satellite has an atomic clock, and sends the current exact time as well.
The GPS receiver figures out which satellites it can hear, and then starts gathering those messages. The messages include time, current satellite positions, and a few other bits of information. The message stream is slow - this is to save power, and also because all the satellites transmit on the same frequency and they're easier to pick out if they go slow. Because of this, and the amount of information needed to operate well, it can take 30-60 seconds to get a location on a regular GPS.
When it knows the position and time code of at least 3 satellites, a GPS receiver can assume it's on the earth's surface and get a good reading. 4 satellites are needed if you aren't on the ground and you want altitude as well.
As you saw above, it can take a long time to get a position fix with a normal GPS. There are ways to speed this up, but unless you're carrying an atomic clock with you all the time, or leave the GPS on all the time, then there's always going to be a delay of between 5-60 seconds before you get a location.
In order to save cost, most cell phones share the GPS receiver components with the cellular components, and you can't get a fix and talk at the same time. People don't like that (especially when there's an emergency) so the lowest form of GPS does the following:
This saves a lot of money on the phone design, but it has a heavy load on cellular bandwidth, and with a lot of requests coming it requires a lot of fast servers. Still, overall it can be cheaper and faster to implement. They are reluctant, however, to release GPS based features on these phones due to this load - so you won't see turn by turn navigation here.
More recent designs include a full GPS chip. They still get data from the phone company - such as current location based on tower positioning, and current satellite locations - this provides sub 1 second fix times. This information is only needed once, and the GPS can keep track of everything after that with very little power. If the cellular network is unavailable, then they can still get a fix after awhile. If the GPS satellites aren't visible to the receiver, then they can still get a rough fix from the cellular towers.
But to completely answer your question - it's as free as the phone company lets it be, and so far they do not charge for it at all. I doubt that's going to change in the future. In the higher end phones with a full GPS receiver you may even be able to load your own software and access it, such as with mologogo on a motorola iDen phone - the J2ME development kit is free, and the phone is only $40 (prepaid phone with $5 credit). Unlimited internet is about $10 a month, so for $40 to start and $10 a month you can get an internet tracking system. (Prices circa August 2008)
It's only going to get cheaper and more full featured from here on out...
Re: Google maps and such
Yes, Google maps and all other cell phone mapping systems require a data connection of some sort at varying times during usage. When you move far enough in one direction, for instance, it'll request new tiles from its server. Your average phone doesn't have enough storage to hold a map of the US, nor the processor power to render it nicely. iPhone would be able to if you wanted to use the storage space up with maps, but given that most iPhones have a full time unlimited data plan most users would rather use that space for other things.
plt.plot(X,y)
function just draws the plot on the canvas. In order to view the plot, you have to specify plt.show()
after plt.plot(X,y)
. So,
import matplotlib.pyplot as plt
X = //your x
y = //your y
plt.plot(X,y)
plt.show()
If you want to remove files following a certain pattern and you are using git rm --cached
, you can use file-glob patterns too.

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (!string.IsNullOrEmpty(displayFormat) && value != null)
{
DateTime date;
displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
// use the format specified in the DisplayFormat attribute to parse the date
if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
{
return date;
}
else
{
bindingContext.ModelState.AddModelError(
bindingContext.ModelName,
string.Format("{0} is an invalid date format", value.AttemptedValue)
);
}
}
return base.BindModel(controllerContext, bindingContext);
}
Hope this could help someone else...

matcher.find()
does not find all matches, only the next match.
long matches = matcher.results().count();
You'll have to do the following. (Starting from Java 9, there is a nicer solution)
int count = 0;
while (matcher.find())
count++;
Btw, matcher.groupCount()
is something completely different.
Complete example:
import java.util.regex.*;
class Test {
public static void main(String[] args) {
String hello = "HelloxxxHelloxxxHello";
Pattern pattern = Pattern.compile("Hello");
Matcher matcher = pattern.matcher(hello);
int count = 0;
while (matcher.find())
count++;
System.out.println(count); // prints 3
}
}
When counting matches of aa
in aaaa
the above snippet will give you 2.
aaaa
aa
aa
To get 3 matches, i.e. this behavior:
aaaa
aa
aa
aa
You have to search for a match at index <start of last match> + 1
as follows:
String hello = "aaaa";
Pattern pattern = Pattern.compile("aa");
Matcher matcher = pattern.matcher(hello);
int count = 0;
int i = 0;
while (matcher.find(i)) {
count++;
i = matcher.start() + 1;
}
System.out.println(count); // prints 3

A common case for simply setting -fpermissive and not sweating it exists: the thoroughly-tested and working third-party library that won't compile on newer compiler versions without -fpermissive. These libraries exist, and are very likely not the application developer's problem to solve, nor in the developer's schedule budget to do it.
Set -fpermissive and move on in that case.
It is just as simple as this.....
//import java.io.FileInputStream;
//import java.io.FileInputStream;
Properties prop = new Properties();
//c:\\myapp\\config.ini is the location of the ini file
//ini file should look like host=localhost
prop.load(new FileInputStream("c:\\myapp\\config.ini"));
String host = prop.getProperty("host");

If you need to handle DOM events not already provided by React you have to add DOM listeners after the component is mounted:
Update: Between React 13, 14, and 15 changes were made to the API that affect my answer. Below is the latest way using React 15 and ES7. See answer history for older versions.
class MovieItem extends React.Component {
componentDidMount() {
// When the component is mounted, add your DOM listener to the "nv" elem.
// (The "nv" elem is assigned in the render function.)
this.nv.addEventListener("nv-enter", this.handleNvEnter);
}
componentWillUnmount() {
// Make sure to remove the DOM listener when the component is unmounted.
this.nv.removeEventListener("nv-enter", this.handleNvEnter);
}
// Use a class arrow function (ES7) for the handler. In ES6 you could bind()
// a handler in the constructor.
handleNvEnter = (event) => {
console.log("Nv Enter:", event);
}
render() {
// Here we render a single <div> and toggle the "aria-nv-el-current" attribute
// using the attribute spread operator. This way only a single <div>
// is ever mounted and we don't have to worry about adding/removing
// a DOM listener every time the current index changes. The attrs
// are "spread" onto the <div> in the render function: {...attrs}
const attrs = this.props.index === 0 ? {"aria-nv-el-current": true} : {};
// Finally, render the div using a "ref" callback which assigns the mounted
// elem to a class property "nv" used to add the DOM listener to.
return (
<div ref={elem => this.nv = elem} aria-nv-el {...attrs} className="menu_item nv-default">
...
</div>
);
}
}

Here's an example:
public class Main {
public static void main(String[] args) {
double val1 = 100;
double val2 = 10;
char operation = 'd';
double result = 0;
switch (operation) {
case 'a':
result = val1 + val2; break;
case 's':
result = val1 - val2; break;
case 'd':
if (val2 != 0)
result = val1 / val2; break;
case 'm':
result = val1 * val2; break;
default: System.out.println("Not a defined operation");
}
System.out.println(result);
}
}
This seems unnecessary, but VBA is a strange place. If you declare an array variable, then set it using Array()
then pass the variable into your function, VBA will be happy.
Sub test()
Dim fString As String
Dim arr() As Variant
arr = Array("foo", "bar")
fString = processArr(arr)
End Sub
Also your function processArr()
could be written as:
Function processArr(arr() As Variant) As String
processArr = Replace(Join(arr()), " ", "")
End Function
If you are into the whole brevity thing.
As @Alexander solves, the issue is one of async data load - you're rendering immediately and you will not have participants loaded until the async ajax call resolves and populates data
with participants
.
The alternative to the solution they provided would be to prevent render until participants exist, something like this:
render: function() {
if (!this.props.data.participants) {
return null;
}
return (
<ul className="PlayerList">
// I'm the Player List {this.props.data}
// <Player author="The Mini John" />
{
this.props.data.participants.map(function(player) {
return <li key={player}>{player}</li>
})
}
</ul>
);
}
In oracle-based products you may use the following statement:

Using the .loc[] accessor:
In [25]: a.loc[a['c1'] == 8].index[0]
Out[25]: 4
Can also use the get_loc() by setting 'c1' as the index. This will not change the original dataframe.
In [17]: a.set_index('c1').index.get_loc(8)
Out[17]: 4

(1) add layer group and array to hold layers and reference to layers as global variables:
var search_group = new L.LayerGroup(); var clickArr = new Array();
(2) add map
(3) Add group layer to map
map.addLayer(search_group);
(4) the add to map function, with a popup that contains a link, which when clicked will have a remove option. This link will have, as its id the lat long of the point. This id will then be compared to when you click on one of your created markers and you want to delete it.
map.on('click', function(e) {
var clickPositionMarker = L.marker([e.latlng.lat,e.latlng.lng],{icon: idMarker});
clickArr.push(clickPositionMarker);
mapLat = e.latlng.lat;
mapLon = e.latlng.lng;
clickPositionMarker.addTo(search_group).bindPopup("<a name='removeClickM' id="+e.latlng.lat+"_"+e.latlng.lng+">Remove Me</a>")
.openPopup();
/* clickPositionMarker.on('click', function(e) {
markerDelAgain();
}); */
});
(5) The remove function, compare the marker lat long to the id fired in the remove:
$(document).on("click","a[name='removeClickM']", function (e) {
// Stop form from submitting normally
e.preventDefault();
for(i=0;i<clickArr.length;i++) {
if(search_group.hasLayer(clickArr[i]))
{
if(clickArr[i]._latlng.lat+"_"+clickArr[i]._latlng.lng==$(this).attr('id'))
{
hideLayer(search_group,clickArr[i]);
clickArr.splice(clickArr.indexOf(clickArr[i]), 1);
}
}
}
