First start with Joran's excellent answer -- doubtful anything can better that.
Then the following mnemonics may help to remember the distinctions between each. Whilst some are obvious, others may be less so --- for these you'll find justification in Joran's discussions.
Mnemonics
lapply
is a list apply which acts on a list or vector and returns a list.sapply
is a simple lapply
(function defaults to returning a vector or matrix when possible)vapply
is a verified apply (allows the return object type to be prespecified)rapply
is a recursive apply for nested lists, i.e. lists within liststapply
is a tagged apply where the tags identify the subsetsapply
is generic: applies a function to a matrix's rows or columns (or, more generally, to dimensions of an array)Building the Right Background
If using the apply
family still feels a bit alien to you, then it might be that you're missing a key point of view.
These two articles can help. They provide the necessary background to motivate the functional programming techniques that are being provided by the apply
family of functions.
Users of Lisp will recognise the paradigm immediately. If you're not familiar with Lisp, once you get your head around FP, you'll have gained a powerful point of view for use in R -- and apply
will make a lot more sense.
In case you want to apply common functions such as sum or mean, you should use rowSums
or rowMeans
since they're faster than apply(data, 1, sum)
approach. Otherwise, stick with apply(data, 1, fun)
. You can pass additional arguments after FUN argument (as Dirk already suggested):
set.seed(1)
m <- matrix(round(runif(20, 1, 5)), ncol=4)
diag(m) <- NA
m
[,1] [,2] [,3] [,4]
[1,] NA 5 2 3
[2,] 2 NA 2 4
[3,] 3 4 NA 5
[4,] 5 4 3 NA
[5,] 2 1 4 4
Then you can do something like this:
apply(m, 1, quantile, probs=c(.25,.5, .75), na.rm=TRUE)
[,1] [,2] [,3] [,4] [,5]
25% 2.5 2 3.5 3.5 1.75
50% 3.0 2 4.0 4.0 3.00
75% 4.0 3 4.5 4.5 4.00
If you want to learn your data summary (df)
provides the min, 1st quantile, median and mean, 3rd quantile and max of numerical columns and the frequency of the top levels of the factor columns.
I faced this problem a few days ago - the solution for me was to use .bind() to bind the required function to the dynamically created link.
var catLink = $('<a href="#" id="' + i + '" class="lnkCat">' + category.category + '</a>');
catLink.bind("click", function(){
$.categories.getSubCategories(this);
});
getSubCategories : function(obj) {
//do something
}
I hope this helps.
I tweaked the previous answers by using the --sort
flag and added some color/formatting:
git for-each-ref --format='%(color:cyan)%(authordate:format:%m/%d/%Y %I:%M %p) %(align:25,left)%(color:yellow)%(authorname)%(end) %(color:reset)%(refname:strip=3)' --sort=authordate refs/remotes
Try this:
With xlApp.ActiveSheet.Pictures.Insert(PicPath)
With .ShapeRange
.LockAspectRatio = msoTrue
.Width = 75
.Height = 100
End With
.Left = xlApp.ActiveSheet.Cells(i, 20).Left
.Top = xlApp.ActiveSheet.Cells(i, 20).Top
.Placement = 1
.PrintObject = True
End With
It's better not to .select anything in Excel, it is usually never necessary and slows down your code.
One thing that might be useful to you (besides the already valid/good answers provided so far) is the StringEnum idea provided here
With this you can define your enumerations as classes (the examples are in vb.net):
< StringEnumRegisteredOnly(), DebuggerStepThrough(), ImmutableObject(True)> Public NotInheritable Class eAuthenticationMethod Inherits StringEnumBase(Of eAuthenticationMethod)
Private Sub New(ByVal StrValue As String) MyBase.New(StrValue) End Sub < Description("Use User Password Authentication")> Public Shared ReadOnly UsernamePassword As New eAuthenticationMethod("UP") < Description("Use Windows Authentication")> Public Shared ReadOnly WindowsAuthentication As New eAuthenticationMethod("W")
End Class
And now you could use the this class as you would use an enum: eAuthenticationMethod.WindowsAuthentication and this would be essentially like assigning the 'W' the logical value of WindowsAuthentication (inside the enum) and if you were to view this value from a properties window (or something else that uses the System.ComponentModel.Description property) you would get "Use Windows Authentication".
I've been using this for a long time now and it makes the code more clear in intent.
If you are aware of bootstrap you can do it easily by using 'flex' property.All you need to do is pass below css properties to parent div
.homepageSection {
overflow: hidden;
height: auto;
display: flex;
flex-flow: row;
}
where .homepageSection
is my parent div.
Now add child div in your html as
<div class="abc col-md-6">
<div class="abc col-md-6">
where abc is my child div.You can check equality of height in both child div irrespective of border just by giving border to child div
Use an relative path to the root of your site, for example:
If clock.js is on http://domain.com/javascript/clock.js
Include :
<script language="JavaScript" src="/javascript/clock.js"></script>
If it's on your domain root directory:
<script language="JavaScript" src="/clock.js"></script>
I would use one of the of the overloads of the IndexOf method
bool found = Value1.IndexOf("abc", 0, 7) != -1;
I wrote a jQuery plugin for doing this. By default it checks the current URL (because that's already loaded once from the Web) or you can specify a URL to use as an argument. Always doing a request to Google isn't the best idea because it's blocked in different countries at different times. Also you might be at the mercy of what the connection across a particular ocean/weather front/political climate might be like that day.
>>> r = re.compile("([a-zA-Z]+)([0-9]+)")
>>> m = r.match("foobar12345")
>>> m.group(1)
'foobar'
>>> m.group(2)
'12345'
So, if you have a list of strings with that format:
import re
r = re.compile("([a-zA-Z]+)([0-9]+)")
strings = ['foofo21', 'bar432', 'foobar12345']
print [r.match(string).groups() for string in strings]
Output:
[('foofo', '21'), ('bar', '432'), ('foobar', '12345')]
I had a similar problem, and the solution for me was quite different from what the other users posted.
The problem with me was related to the project I was working last year, which required a certain proxy on maven settings (located at <path to maven folder>\maven\conf\settings.xml
and C:\Users\<my user>\.m2\settings.xml
). The proxy was blocking the download of required external packages.
The solution was to put back the original file (settings.xml
) on those places. Once things were restored, I was able to download the packages and everything worked.
The +
character has a special meaning in a URL => it means whitespace -
. If you want to use the literal +
sign, you need to URL encode it to %2b
:
body=Hi+there%2bHello+there
Here's an example of how you could properly generate URLs in .NET:
var uriBuilder = new UriBuilder("https://mail.google.com/mail");
var values = HttpUtility.ParseQueryString(string.Empty);
values["view"] = "cm";
values["tf"] = "0";
values["to"] = "[email protected]";
values["su"] = "some subject";
values["body"] = "Hi there+Hello there";
uriBuilder.Query = values.ToString();
Console.WriteLine(uriBuilder.ToString());
The result
Run the Process Monitor to see what resources(Network, File, Registry, Threads) are being consumed and see any unnecessary resource(remote https, costly file reads) are being consumed
I had similar problem. When I run the process monitor I found that my fusion log is enabled so there are many into the disk which delayed the loading of dll after disabling fusion log IIS Express it is faster.
#button {
line-height: 12px;

}
foreach (DataRow row in DataRow row in GridView1.Rows)
{
foreach (DataColumn c in GridView1.Columns)
bool ckbVal = (bool)(row[c.ColumnName]);
}
If you want the text value of a QString object you can use the __str__
property, like this:
>>> a = QtCore.QString("Happy Happy, Joy Joy!")
>>> a
PyQt4.QtCore.QString(u'Happy Happy, Joy Joy!')
>>> a.__str__()
u'Happy Happy, Joy Joy!'
Hope that helps.
It can also be caused by piping out of a pair of curly braces on a line.
This fails:

while this is allowed:

If you really want to run Jenkins as you, I suggest you check out my Jenkins.app. An alternative, easy way to run Jenkins on Mac.
See https://github.com/stisti/jenkins-app/
Download it from https://github.com/stisti/jenkins-app/downloads
On a Mac, credentials are stored in Keychain Access. Look for Github and remove that credential. More info: https://help.github.com/articles/updating-credentials-from-the-osx-keychain/
Similar to @Sijmen's answer, this is what worked for me on OSX when renaming a directory (inspired by this answer from another post):
git mv CSS CSS2
git mv CSS2 css
Simply doing git mv CSS css
gave the invalid argument error: fatal: renaming '/static/CSS' failed: Invalid argument
perhaps because OSX's file system is case insensitive
p.s BTW if you are using Django, collectstatic also wouldn't recognize the case difference and you'd have to do the above, manually, in the static root directory as well
You can use replace_entities from w3lib.html library
In [202]: from w3lib.html import replace_entities
In [203]: replace_entities("£682m")
Out[203]: u'\xa3682m'
In [204]: print replace_entities("£682m")
£682m
None of the other answers were working for me immediately on ElementaryOS Freya (based on Ubuntu 14.04); I was getting the
[TerminalIPythonApp] WARNING | File not found: 'kernelspec'
error that quickbug described under Matt's answer. I had to first do:
sudo apt-get install pip3
, then
sudo pip3 install ipython[all]
At that point you can then run the commands that Matt suggested; namely: ipython kernelspec install-self
and ipython3 kernelspec install-self
Now when I launch ipython notebook
and then open a notebook, I am able to select the Python 3 kernel from the Kernel menu.
If you use Android, you can simply use android.text.format.Formatter.formatFileSize().
Alternatively, here's a solution based on this popular post:
/**
* Formats the bytes to a human readable format
*
* @param si true if each kilo==1000, false if kilo==1024
*/
@SuppressLint("DefaultLocale")
public static String humanReadableByteCount(final long bytes, final boolean si)
{
final int unit = si ? 1000 : 1024;
if(bytes<unit)
return bytes + " B";
double result = bytes;
final String unitsToUse = (si ? "k" : "K") + "MGTPE";
int i = 0;
final int unitsCount = unitsToUse.length();
while(true)
{
result /= unit;
if(result < unit)
break;
// Check if we can go further:
if(i == unitsCount-1)
break;
++i;
}
final StringBuilder sb = new StringBuilder(9);
sb.append(String.format("%.1f ", result));
sb.append(unitsToUse.charAt(i));
if(si)
sb.append('B');
else sb.append('i').append('B');
final String resultStr = sb.toString();
return resultStr;
}
Or in Kotlin:
/**
* formats the bytes to a human readable format
*
* @param si true if each kilo==1000, false if kilo==1024
*/
@SuppressLint("DefaultLocale")
fun humanReadableByteCount(bytes: Long, si: Boolean): String? {
val unit = if (si) 1000.0 else 1024.0
if (bytes < unit)
return "$bytes B"
var result = bytes.toDouble()
val unitsToUse = (if (si) "k" else "K") + "MGTPE"
var i = 0
val unitsCount = unitsToUse.length
while (true) {
result /= unit
if (result < unit || i == unitsCount - 1)
break
++i
}
return with(StringBuilder(9)) {
append(String.format("%.1f ", result))
append(unitsToUse[i])
if (si) append('B') else append("iB")
}.toString()
}
I just want to share the code I created that might help you.
DECLARE @MyCounter int = 0, @TempDate datetime, @EndDate datetime;
SET @TempDate = DATEADD(d,1,'2017-5-27')
SET @EndDate = '2017-6-3'
WHILE @TempDate <= @EndDate
BEGIN
IF DATENAME(DW,@TempDate) = 'Sunday' OR DATENAME(DW,@TempDate) = 'Saturday'
SET @MyCounter = @MyCounter
ELSE IF @TempDate not in ('2017-1-1', '2017-1-16', '2017-2-20', '2017-5-29', '2017-7-4', '2017-9-4', '2017-10-9', '2017-11-11', '2017-12-25')
SET @MyCounter = @MyCounter + 1
SET @TempDate = DATEADD(d,1,@TempDate)
CONTINUE
END
PRINT @MyCounter
PRINT @TempDate
If you do have a holiday table, you can also use that so that you don't have to list all the holidays in the ELSE IF section of the code. You can also create a function for this code and use the function whenever you need it in your query.
I hope this might help too.
You should check Force Update Snapshots/Releases
when updating project with maven.It worked for me :-).
I did not find any of the answers satisfactory. All the mentioned libraries have some problem or the other like Cairo dropping support for python 3.6 (they dropped Python 2 support some 3 years ago!). Also, installing the mentioned libraries on the Mac was a pain.
Finally, I found the best solution was svglib + reportlab. Both installed without a hitch using pip and first call to convert from svg to png worked beautifully! Very happy with the solution.
Just 2 commands do the trick:
from svglib.svglib import svg2rlg
from reportlab.graphics import renderPM
drawing = svg2rlg("my.svg")
renderPM.drawToFile(drawing, "my.png", fmt="PNG")
Are there any limitations with these I should be aware of?
You can get the path via fp.name
. Example:
>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'
You might need os.path.basename
if you want only the file name:
>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'
File object docs (for Python 2) here.
SELECT *
FROM table
WHERE date BETWEEN
ADDDATE(LAST_DAY(DATE_SUB(NOW(),INTERVAL 2 MONTH)), INTERVAL 1 DAY)
AND DATE_SUB(NOW(),INTERVAL 1 MONTH);
See the docs for info on DATE_SUB
, ADDDATE
, LAST_DAY
and other useful datetime functions.
These are the default settings I have for /etc/network/interfaces (including WiFi settings) for my Raspberry Pi 1:
auto lo
iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
My issue was simpler than all the answers in this post.
I had to setup IIS to include static content.
function coalesce() {
var len = arguments.length;
for (var i=0; i<len; i++) {
if (arguments[i] !== null && arguments[i] !== undefined) {
return arguments[i];
}
}
return null;
}
var xyz = {};
xyz.val = coalesce(null, undefined, xyz.val, 5);
// xyz.val now contains 5
this solution works like the SQL coalesce function, it accepts any number of arguments, and returns null if none of them have a value. It behaves like the C# ?? operator in the sense that "", false, and 0 are considered NOT NULL and therefore count as actual values. If you come from a .net background, this will be the most natural feeling solution.
Create this class as Extension:
public static class Extensiones
{
public static string FolderName(this OpenFileDialog ofd)
{
string resp = "";
resp = ofd.FileName.Substring(0, 3);
var final = ofd.FileName.Substring(3);
var info = final.Split('\\');
for (int i = 0; i < info.Length - 1; i++)
{
resp += info[i] + "\\";
}
return resp;
}
}
Then, you could use in this way:
//ofdSource is an OpenFileDialog
if (ofdSource.ShowDialog(this) == DialogResult.OK)
{
MessageBox.Show(ofdSource.FolderName());
}
Couldn't you just call the following replaceing the {zipcode} with the zip code or city and state http://maps.googleapis.com/maps/api/geocode/json?address={zipcode}
Here is a link with a How To Geocode using JavaScript: Geocode walk-thru. If you need the specific lat/lng numbers call geometry.location.lat() or geometry.location.lng() (API for google.maps.LatLng class)
EXAMPLE to get lat/lng:
var lat = '';
var lng = '';
var address = {zipcode} or {city and state};
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
lat = results[0].geometry.location.lat();
lng = results[0].geometry.location.lng();
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
alert('Latitude: ' + lat + ' Logitude: ' + lng);
ExecuteScalar
is typically used when your query returns a single value. If it returns more, then the result is the first column of the first row. An example might be SELECT @@IDENTITY AS 'Identity'
.ExecuteReader
is used for any result set with multiple rows/columns (e.g., SELECT col1, col2 from sometable
).ExecuteNonQuery
is typically used for SQL statements without results (e.g., UPDATE, INSERT, etc.).It is possible without any Javascript :)
The HTML:
<div class='box'>
<div class='content'>Aspect ratio of 1:1</div>
</div>
The CSS:
.box {
position: relative;
width: 50%; /* desired width */
}
.box:before {
content: "";
display: block;
padding-top: 100%; /* initial ratio of 1:1*/
}
.content {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
/* Other ratios - just apply the desired class to the "box" element */
.ratio2_1:before{

}
.ratio4_3:before{
padding-top: 75%;

}
Use DispatchGroup
s to achieve this. You can either get notified when the group's enter()
and leave()
calls are balanced:
func myFunction() {
var a: Int?
let group = DispatchGroup()
group.enter()
DispatchQueue.main.async {
a = 1
group.leave()
}
// does not wait. But the code in notify() gets run
// after enter() and leave() calls are balanced
group.notify(queue: .main) {
print(a)
}
}
or you can wait:
func myFunction() {
var a: Int?
let group = DispatchGroup()
group.enter()
// avoid deadlocks by not using .main queue here
DispatchQueue.global(attributes: .qosDefault).async {
a = 1
group.leave()
}
// wait ...
group.wait()
print(a) // you could also `return a` here
}
Note: group.wait()
blocks the current queue (probably the main queue in your case), so you have to dispatch.async
on another queue (like in the above sample code) to avoid a deadlock.

return 0;
}
This happened with me as well and I believe this has become a common error not only for Django developers but also for Flask as well, so the way I solved this issue was using brew.
brew install mysql
sudo pip install mysql-python
This way every single issue was solved and both frameworks work absolutely fine.
P.S.: For those who use macports (such as myself), this can be an issue as brew works in a different level, my advice is to use brew instead of macports
I hope I could be helpful.
There's a plugin called Job Import Plugin that may be what you are looking for. I have used it. It does have issues with importing projects from a server that doesn't allow anonymous access.
For Completeness: If you have command line access to both, you can do the procedure already mentioned by Khez for Moving, Copying and Renaming Jenkins Jobs.
I don't like any of the other answers. The ActivityManager is not meant to be used for getting the current activity. Super classing and depending on onDestroy is also fragile and not the best design.
Honestly, the best I have came up with so far is just maintaining an enum in my Application, which gets set when an activity is created.
Another recommendation might be to just shy away from using multiple activities if possible. This can be done either with using fragments, or in my preference custom views.
I think you're saying you want to remove all non-numeric characters. If so, \D
means "anything that isn't a digit":
preg_replace('/\D/', '', $c)
I think that you can do something like this.
class custom(object):
__custom__ = True
class Alpha(custom):
something = 3
def GetClasses():
return [x for x in globals() if hasattr(globals()[str(x)], '__custom__')]
print(GetClasses())`
if you need own classes
A simple example:
public class Test extends Thread {
public synchronized void run() {
for (int i = 0; i <= 10; i++) {
System.out.println("i::"+i);
}
}
public static void main(String[] args) {
Test obj = new Test();
Thread t1 = new Thread(obj);
Thread t2 = new Thread(obj);
Thread t3 = new Thread(obj);
t1.start();
t2.start();
t3.start();
}
}
Its pretty straight forward. Type the below command
ssh-keygen -t rsa -b 4096 -C "[email protected]"
Generate the SSH key. Open the file and copy the contents. Go to GitHub setting page , and click on SSH key . Click on Add new SSH key, and paste the contents here. That's it :) You shouldn't see the issue again.
Just try this in razor
@{
var selectList = new SelectList(
new List<SelectListItem>
{
new SelectListItem {Text = "Google", Value = "Google"},
new SelectListItem {Text = "Other", Value = "Other"},
}, "Value", "Text");
}
and then
@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })
or
@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })
I suggest you to start with simple polynomial fit, scipy.optimize.curve_fit
tries to fit a function f
that you must know to a set of points.
This is a simple 3 degree polynomial fit using numpy.polyfit
and poly1d
, the first performs a least squares polynomial fit and the second calculates the new points:
import numpy as np
import matplotlib.pyplot as plt
points = np.array([(1, 1), (2, 4), (3, 1), (9, 3)])
# get x and y vectors
x = points[:,0]
y = points[:,1]
# calculate polynomial
z = np.polyfit(x, y, 3)
f = np.poly1d(z)
# calculate new x's and y's
x_new = np.linspace(x[0], x[-1], 50)
y_new = f(x_new)
plt.plot(x,y,'o', x_new, y_new)
plt.xlim([x[0]-1, x[-1] + 1 ])
plt.show()
Hmm, many of these responses have long and hard to read code...
I'd suggest using numpy with its nifty features when working with arrays:
import numpy as np
def pcc(X, Y):
''' Compute Pearson Correlation Coefficient. '''
# Normalise X and Y
X -= X.mean(0)
Y -= Y.mean(0)
# Standardise X and Y
X /= X.std(0)
Y /= Y.std(0)
# Compute mean product
return np.mean(X*Y)
# Using it on a random example
from random import random
X = np.array([random() for x in xrange(100)])
Y = np.array([random() for x in xrange(100)])
pcc(X, Y)
I am surprised no one has a link for this . any format can be created using the guidelines here:
Custom Date and Time Format Strings
For your specific example (As others have indicated) use something like
my_format="yyyyMMddHHmmss";
DateTime.Now.ToString(my_format);
Where my_format can be any string combination of y,M,H,m,s,f,F and more! Check out the link.
I'm created RunApp to do such a job and also using it in my production env, hope it's helps.

And launch runapp.exe
instead.
It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.
In your case the variable can be declared like this:
<variable name="total" class="java.lang.Integer" calculation="Sum">
<variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>
The working example.

I do not know why there is no answer directly addressing the problem. When you
want to compile C++ program, it is best to use clang++
. For example, the
following works for me:
clang++ -Wall -std=c++11 test.cc -o test
If compiled correctly, it will produce the executable file test
, and you can
run the file by using ./test
.
Or you can just use clang++ test.cc
to compile the program. It will produce a
default executable file named a.out
. Use ./a.out
to run the file.
The whole process is a lot like g++ if you are familiar with g++. See this
post to check which warnings are included with -Wall
option. This
page shows a list of diagnostic flags supported by Clang.
A note on using clang -x c++
: Kim Gräsman says that you can also use
clang -x c++
to compile cpp programs, but that may not be true. For example,
I am having a simple program below:
#include <iostream>
#include <vector>
int main() {
/* std::vector<int> v = {1, 2, 3, 4, 5}; */
std::vector<int> v(10, 5);
int sum = 0;
for (int i = 0; i < v.size(); i++){
sum += v[i]*2;
}
std::cout << "sum is " << sum << std::endl;
return 0;
}
clang++ test.cc -o test
will compile successfully, but clang -x c++
will
not, showing a lot undefined references errors. So I guess they are not exactly
equivalent. It is best to use clang++
instead of clang -x c++
when
compiling c++ programs to avoid extra troubles.
in the "Ouput Window". you can usually do CTRL-ALT-O to make it visible. Or through menus using View->Output.
What about:
if (urldecode(trim($url)) == trim($url)) { $url_form = 'decoded'; }
else { $url_form = 'encoded'; }
Will not work with double encoding but this is out of scope anyway I suppose?
if you set your context model as code first based on exist database so you have to for set migration:
Add-Migration InitialCreate –IgnoreChanges
Update-database -force
and then change your context model and set:
Add-migration RemoveIspositive
Update-database -force
From the grep(1)
man page:
-l, --files-with-matches Suppress normal output; instead print the name of each input file from which output would normally have been printed. The scanning will stop on the first match. (-l is specified by POSIX.)
If multiple criteria use countifs
=countifs(A1:A10,">""",B1:B10,">""")
The " >"" "
looks at the greater than being empty. This formula looks for two criteria and neither column can be empty on the same row for it to count. If just counting one column do this with the one criteria (i.e. Use everything before B1:B10
not including the comma)
Use Ctrl+H for opening Eclipse search dialog, select appropriate search tab and select "Replace..." to get you to the "Search and replace" dialog
(copy-paste/adapted from https://stackoverflow.com/a/24048772/1733117).
First you can subclass urllib2.BaseHandler
or urllib2.HTTPBasicAuthHandler
, and implement http_request
so that each request has the appropriate Authorization
header.
import urllib2
import base64
class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
'''Preemptive basic auth.
Instead of waiting for a 403 to then retry with the credentials,
send the credentials if the url is handled by the password manager.
Note: please use realm=None when calling add_password.'''
def http_request(self, req):
url = req.get_full_url()
realm = None
# this is very similar to the code from retry_http_basic_auth()
# but returns a request object.
user, pw = self.passwd.find_user_password(realm, url)
if pw:
raw = "%s:%s" % (user, pw)
auth = 'Basic %s' % base64.b64encode(raw).strip()
req.add_unredirected_header(self.auth_header, auth)
return req
https_request = http_request
Then if you are lazy like me, install the handler globally
api_url = "http://api.foursquare.com/"
api_username = "johndoe"
api_password = "some-cryptic-value"
auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
realm=None, # default realm.
uri=api_url,
user=api_username,
passwd=api_password)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
The most elegant solution to this problem is here.
Original answer remains, but this is a messy solution:
If you want to change the PYTHONPATH
used in a virtualenv, you can add the following line to your virtualenv's bin/activate
file:
export PYTHONPATH="/the/path/you/want"
This way, the new PYTHONPATH
will be set each time you use this virtualenv.
EDIT: (to answer @RamRachum's comment)
To have it restored to its original value on deactivate
, you could add
export OLD_PYTHONPATH="$PYTHONPATH"
before the previously mentioned line, and add the following line to your bin/postdeactivate
script.
export PYTHONPATH="$OLD_PYTHONPATH"
The only easy solution that I have applied is to recreate the primary condition that do the highlights as an IF
condition and use it on the IF
formula. Something like this. Depending on the highlight condition the formula will change but I think that should be recreated (es. highlight greater than 20).
=IF(B3>20,(B3)," ")
To target IE10 and IE11 only (and not Edge):
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
/* add your IE10-IE11 css here */
}
I was having this error message inside a docker container. I resolved it adding:
WORKDIR /usr/src
to Dockerfile.
You can do this:
And to capture locale. You can do this:
private static final String LOCALE = LocaleContextHolder.getLocale().getLanguage()
+ "-" + LocaleContextHolder.getLocale().getCountry();
Another interesting solution to luch an exeternal application with a WinForm container is the follow:
[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
private void Form1_Load(object sender, EventArgs e)
{
ProcessStartInfo psi = new ProcessStartInfo("notepad.exe");
psi.WindowStyle = ProcessWindowStyle.Minimized;
Process p = Process.Start(psi);
Thread.Sleep(500);
SetParent(p.MainWindowHandle, panel1.Handle);
CenterToScreen();
psi.WindowStyle = ProcessWindowStyle.Normal;
}
The step to ProcessWindowStyle.Minimized
from ProcessWindowStyle.Normal remove the annoying delay.
Solution: In order to increase your buffer history on iterm bash terminal you've got two options:
Go to iterm -> Preferences -> Profiles -> Terminal Tab -> Scrollback Buffer (section)
Option 1. select the checkbox Unlimited scrollback
Option 2. type the selected Scrollback lines
numbers you'd like your terminal buffer to cache (See image below)
The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element
to do DOM operations. The method defined in the directive controller is accessible in the main controller.
Example, finding a child element:
var app = angular.module('myapp', []);
app.directive("testDir", function () {
function link(scope, element) {
}
return {
restrict: "AE",
link: link,
controller:function($scope,$element){
$scope.name2 = 'this is second name';
var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
}
};
})
app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});
I am coming from an Electron environment, where I need IPC communication between a renderer process and the main process. The renderer process sits in an HTML file between script tags and generates the same error.
The line
const {ipcRenderer} = require('electron')
throws the Uncaught ReferenceError: require is not defined
I was able to work around that by specifying Node.js integration as true when the browser window (where this HTML file is embedded) was originally created in the main process.
function createAddItemWindow() {
// Create a new window
addItemWindown = new BrowserWindow({
width: 300,
height: 200,
title: 'Add Item',
// The lines below solved the issue
webPreferences: {
nodeIntegration: true
}
})}
That solved the issue for me. The solution was proposed here.
Certainly, how it's done depends on your shell. In Bash, you can use single quotes around the message and can just leave the quote open, which will make Bash prompt for another line, until you close the quote. Like this:
git commit -m 'Message
goes
here'
Alternatively, you can use a "here document" (also known as heredoc):
git commit -F- <<EOF
Message
goes
here
EOF
I've just gone through that process again. Always end up cloning the repo locally, upload the folder I want to have in that repo to that cloned location, commit the changes and then push it.
Note that if you're dealing with large files, you'll need to consider using something like Git LFS.
Angular has released its final version on 15th of September. Unlike Angular 1 you can use ngModel
directive in Angular 2 for two way data binding, but you need write it in a bit different way like [(ngModel)]
(Banana in a box syntax). Almost all angular2 core directives doesn't support kebab-case
now instead you should use camelCase
.
Now
ngModel
directive belongs toFormsModule
, that's why you shouldimport
theFormsModule
from@angular/forms
module insideimports
metadata option ofAppModule
(NgModule). Thereafter you can usengModel
directive inside on your page.
app/app.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `<h1>My First Angular 2 App</h1>
<input type="text" [(ngModel)]="myModel"/>
{{myModel}}
`
})
export class AppComponent {
myModel: any;
}
app/app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule, FormsModule ], //< added FormsModule here
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
app/main.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
You can download and run the setup file. This should install your AWK
in "C:\Program Files (x86)\GnuWin32
". You can run the awk
or gawk
command from the bin
folder or add the folder ``C:\Program Files (x86)\GnuWin32\binto your
PATH`.
To correctly save the instance state of Fragment
you should do the following:
1. In the fragment, save instance state by overriding onSaveInstanceState()
and restore in onActivityCreated()
:
class MyFragment extends Fragment {
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
...
if (savedInstanceState != null) {
//Restore the fragment's state here
}
}
...
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//Save the fragment's state here
}
}
2. And important point, in the activity, you have to save the fragment's instance in onSaveInstanceState()
and restore in onCreate()
.
class MyActivity extends Activity {
private MyFragment
public void onCreate(Bundle savedInstanceState) {
...
if (savedInstanceState != null) {
//Restore the fragment's instance
mMyFragment = getSupportFragmentManager().getFragment(savedInstanceState, "myFragmentName");
...
}
...
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//Save the fragment's instance
getSupportFragmentManager().putFragment(outState, "myFragmentName", mMyFragment);
}
}
Hope this helps.
If you have a file in your repo that it is supposed to be customized by most pullers, then rename the file to something like config.php.template
and add config.php
to your .gitignore
.

Use
document.write(document.location.hostname)?
window.location
has a bunch of properties. See here for a list of them.
Use which(mydata_2$height_chad1 == 2585)
Short example
df <- data.frame(x = c(1,1,2,3,4,5,6,3),
y = c(5,4,6,7,8,3,2,4))
df
x y
1 1 5
2 1 4
3 2 6
4 3 7
5 4 8
6 5 3
7 6 2
8 3 4
which(df$x == 3)
[1] 4 8
length(which(df$x == 3))
[1] 2
count(df, vars = "x")
x freq
1 1 2
2 2 1
3 3 2
4 4 1
5 5 1
6 6 1
df[which(df$x == 3),]
x y
4 3 7
8 3 4
As Matt Weller pointed out, you can use the length
function.
The count
function in plyr
can be used to return the count of each unique column value.
This should work
<option *ngFor="let title of titleArray"
[value]="title.Value"
[attr.selected]="passenger.Title==title.Text ? true : null">
{{title.Text}}
</option>
I'm not sure the attr.
part is necessary.
If you want the latest file in the directory and you are using only the LastWriteTime
to determine the latest file, you can do something like below:
gci path | sort LastWriteTime | select -last 1
On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar
gci path | select -last 1
Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}
Yes. It calls the render() method every time we call setState only except when "shouldComponentUpdate" returns false.
Another thing to remember is that request.POST['keyword']
refers to the element identified by the specified html name
attribute keyword
.
So, if your form is:
<form action="/login/" method="POST">
<input type="text" name="keyword" placeholder="Search query">
<input type="number" name="results" placeholder="Number of results">
</form>
then, request.POST['keyword']
and request.POST['results']
will contain the value of the input elements keyword
and results
, respectively.
I had the same problem. I restarted Visual Studio and that fixed the problem
In charSequence you don't have very useful methods which are available for String. If you don't want to look in the documentation, type: obj. and str.
and see what methods your compilator offers you. That's the basic difference for me.
A return value of the previously executed process.
10.4 Getting the return value of a program
In bash, the return value of a program is stored in a special variable called $?.
This illustrates how to capture the return value of a program, I assume that the directory dada does not exist. (This was also suggested by mike)
#!/bin/bash cd /dada &> /dev/null echo rv: $? cd $(pwd) &> /dev/null echo rv: $?
See Bash Programming Manual for more details.

For a simple java String
Array you should try
String arr_str [] = { "value1`", "value2", "value3" };
JSONArray arr_strJson = new JSONArray(Arrays.asList(arr_str));
System.out.println(arr_strJson.toString());
If you have an Generic ArrayList of type String like ArrayList<String>
. then you should try
ArrayList<String> obj_list = new ArrayList<>();
obj_list.add("value1");
obj_list.add("value2");
obj_list.add("value3");
JSONArray arr_strJson = new JSONArray(obj_list));
System.out.println(arr_strJson.toString());
You can always use material button if you are using Material App as your main Widget.
Padding(
padding: EdgeInsets.symmetric(vertical: 16.0),

Command line arguments are accessible via String[] args
parameter of main
method.
For first argument you can check args[0]
entire code would look like
public static void main(String[] args) {
if ("a".equals(args[0])) {
// do something
}
}
Check here: http://www.allapplabs.com/java_design_patterns/abstract_factory_pattern.htm it seems that Factory method uses a particular class(not abstract) as a base class while Abstract factory uses an abstract class for this. Also if using an interface instead of abstract class the result will be a different implementation of Abstract Factory pattern.

Curl does that by default without any parameters or flags, I would use it for your purposes:

Curl is more about streams and wget is more about copying sites based on this comparison.

The right way to import a module located on a parent folder, when you don't have a standard package structure, is:
import os, sys
CURRENT_DIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(os.path.dirname(CURRENT_DIR))
(you can merge the last two lines but this way is easier to understand).
This solution is cross-platform and is general enough to need not modify in other circumstances.

The function is called like saveAsFile('out.json', jsonString);
. It will create a ByteStream immediately recognized by the browser that will download the generated file directly using the File API URL.createObjectURL
.
In the else
, it is possible to see the same result obtained via the href
element plus the Data API, but this has several limitations that the Blob API has not.
add this code to your ApplicationController

( Dont know why no one above just mention this code as it fixed my problem ) http://apidock.com/rails/ActionController/RackDelegation/reset_session
Just adding this for multiple filters attaching to Q
object, if someone might be looking to it.
If a Q
object is provided, it must precede the definition of any keyword arguments. Otherwise its an invalid query. You should be careful when doing it.
an example would be
from django.db.models import Q
User.objects.filter(Q(income__gte=5000) | Q(income__isnull=True),category='income')
Here the OR condition and a filter with category of income is taken into account
image-rendering
CSS property.<img>
tag using object-fit CSS property.Try this in your CSS:
.your-class-name {
/* ... */
-webkit-backface-visibility: hidden;
-webkit-transform: translateZ(0) scale(1, 1);
}
What this does is it makes the division to behave "more 2D".
backface-visibility
and transform
without the -webkit-
prefix. I currently don't know how this affects other browsers rendering (FF, IE), so use the non-prefixed versions with caution.You should iterate over the keys and get the values using square brackets.
See: How do I enumerate the properties of a javascript object?
EDIT: Obviously, this makes the question a duplicate.
Apparently, org.json.simple.JSONArray
implements a raw Iterator. This means that each element is considered to be an Object
. You can try to cast:
for(Object o: arr){
if ( o instanceof JSONObject ) {
parse((JSONObject)o);
}
}
This is how things were done back in Java 1.4 and earlier.
Building upon Fabien Kruba's already excellent answer, I thought it would be nice if the **
portion of the URL could be given as a parameter to the controller method via an annotation, in a way which was similar to @RequestParam
and @PathVariable
, rather than always using a utility method which explicitly required the HttpServletRequest
. So here's an example of how that might be implemented. Hopefully someone finds it useful.
Create the annotation, along with the argument resolver:
@Target(ElementType.PARAMETER)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface WildcardParam {
class Resolver implements HandlerMethodArgumentResolver {
@Override
public boolean supportsParameter(MethodParameter methodParameter) {
return methodParameter.getParameterAnnotation(WildcardParam.class) != null;
}
@Override
public Object resolveArgument(MethodParameter methodParameter, ModelAndViewContainer modelAndViewContainer, NativeWebRequest nativeWebRequest, WebDataBinderFactory webDataBinderFactory) throws Exception {
HttpServletRequest request = nativeWebRequest.getNativeRequest(HttpServletRequest.class);
return request == null ? null : new AntPathMatcher().extractPathWithinPattern(
(String) request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE),
(String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE));
}
}
}
Register the method argument resolver:
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) {
resolvers.add(new WildcardParam.Resolver());
}
}
Use the annotation in your controller handler methods to have easy access to the **
portion of the URL:
@RestController
public class SomeController {
@GetMapping("/**")
public void someHandlerMethod(@WildcardParam String wildcardParam) {
// use wildcardParam here...
}
}
Perhaps the shortest possible ways to evaluate an expression into "10" without digits are:
+!+[] + [+[]]
// "10"
-~[] + [+[]]
// "10"
//========== Explanation ==========\\
+!+[]
: +[]
Converts to 0. !0
converts to true
. +true
converts to 1.
-~[]
= -(-1)
which is 1
[+[]]
: +[]
Converts to 0. [0]
is an array with a single element 0.
Then JS evaluates the 1 + [0]
, thus Number + Array
expression. Then the ECMA specification works: +
operator converts both operands to a string by calling the toString()/valueOf()
functions from the base Object
prototype. It operates as an additive function if both operands of an expression are numbers only. The trick is that arrays easily convert their elements into a concatenated string representation.
Some examples:
1 + {} // "1[object Object]"
1 + [] // "1"
1 + new Date() // "1Wed Jun 19 2013 12:13:25 GMT+0400 (Caucasus Standard Time)"
There's a nice exception that two Objects
addition results in NaN
:
[] + [] // ""
[1] + [2] // "12"
{} + {} // NaN
{a:1} + {b:2} // NaN
[1, {}] + [2, {}] // "1,[object Object]2,[object Object]"
If you really want to submit the GET request with JSON in the body (say for an XHR request and you know the server supports processing the body on GET requests), you can:
curl -X GET \
-H "Content-type: application/json" \
-H "Accept: application/json" \
-d '{"param0":"pradeep"}' \
"http://server:5050/a/c/getName"
Most modern web servers accept this type of request.
For python2 users on MacOS (python@2 formula won't be found), as brew stopped support of python2 you need to use such command! But don't forget to unlink old python if it was pre-installed.
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/86a44a0a552c673a05f11018459c9f5faae3becc/Formula/[email protected]
If you've done some mistake, simply brew uninstall python@2
old way, and try again.
This should do the trick:
image = open("image.png", "wb")
image.write(base64string.decode('base64'))
image.close()
@Entity
@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames = "column1"),@UniqueConstraint(columnNames = "column2")})
-- Here both Column1 and Column2 acts as unique constraints separately. Ex : if any time either the value of column1 or column2 value matches then you will get UNIQUE_CONSTRAINT Error.
@Entity
@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames ={"column1","column2"})})
-- Here both column1 and column2 combined values acts as unique constraints
Install Bootstrap using npm
npm install bootstrap
2.Install Popper.js
npm install --save popper.js
3.Goto angular.json in Angular 6 project / .angular-cli.json in Angular 5 and add the listed:
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.css",
"src/styles.css"
],
"scripts": [
"node_modules/popper.js/dist/umd/popper.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
The in
operator only works on objects. You are using it on a string. Make sure your value is an object before you using $.each
. In this specific case, you have to parse the JSON:
$.each(JSON.parse(myData), ...);
// First Get DataTable as dt
// DataRowComparer Compare columns numbers in each row & data in each row
IEnumerable<DataRow> Distinct = dt.AsEnumerable().Distinct(DataRowComparer.Default);
foreach (DataRow row in Distinct)
{
Console.WriteLine("{0,-15} {1,-15}",
row.Field<int>(0),
row.Field<string>(1));
}
Place the following in the CODE MODULE of a WORKSHEET to track the last value for every cell in the used range:
Option Explicit
Private r As Range
Private Const d = "||"
Public Function ValueLast(r As Range)
On Error Resume Next
ValueLast = Split(r.ID, d)(1)
End Function
Private Sub Worksheet_Activate()
For Each r In Me.UsedRange: Record r: Next
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
For Each r In Target: Record r: Next
End Sub
Private Sub Record(r)
r.ID = r.Value & d & Split(r.ID, d)(0)
End Sub
And that's it.
This solution uses the obscure and almost never used Range.ID property, which allows the old values to persist when the workbook is saved and closed.
At any time you can get at the old value of a cell and it will indeed be different than a new current value:
With Sheet1
MsgBox .[a1].Value
MsgBox .ValueLast(.[a1])
End With
This works for me:
function animateRotate (object,fromDeg,toDeg,duration){
var dummy = $('<span style="margin-left:'+fromDeg+'px;">')
$(dummy).animate({
"margin-left":toDeg+"px"
},{
duration:duration,
step: function(now,fx){
$(object).css('transform','rotate(' + now + 'deg)');
}
});
};
You can use this shell script to clean up the folder and files within C:\Temp
source:
del /q "C:\Temp\*"
FOR /D %%p IN ("C:\Temp\*.*") DO rmdir "%%p" /s /q
Create a batch file (say, delete.bat) containing the above command. Go to the location where the delete.bat file is located and then run the command: delete.bat
I don't know why but its happened when you submit a form inside a page to itself by the POST
method.
So change the method="post"
to method="get"
or remove action="anyThings.any"
from your <form>
tag.
The simplest way to do this is by using object-fit
:
<div class="container">
<img src="path/to/image.jpg">
</div>
.container{
height: 300px;
}
.container img{
height: 100%;
width: 100%;
object-fit: cover;
}
If you're using Bootstrap, just add the img-responsive
class and change to
.container img{
object-fit: cover;
}
I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?
Basically, you use the /B
and /C
options:
START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1
If you're already on EL 3.0 (Java EE 7; WildFly, Tomcat 8, GlassFish 4, etc), then you could use the new +=
operator for this:
<c:out value="${empty value ? 'none' : value += ' enabled'}" />
If you're however not on EL 3.0 yet, and the value
is a genuine java.lang.String
instance (and thus not e.g. java.lang.Long
), then use EL 2.2 (Java EE 7; JBoss AS 6/7, Tomcat 7, GlassFish 3, etc) capability of invoking direct methods with arguments, which you then apply on String#concat()
:
<c:out value="${empty value ? 'none' : value.concat(' enabled')}" />
Or if you're even not on EL 2.2 yet, then use JSTL <c:set>
to create a new EL variable with the concatenated values just inlined in value:
<c:set var="enabled" value="${value} enabled" />
<c:out value="${empty value ? 'none' : enabled}" />
To get GCC to print out the complete set of directories where it will look for system headers, invoke it like this:
$ LC_ALL=C gcc -v -E -xc - < /dev/null 2>&1 |
LC_ALL=C sed -ne '/starts here/,/End of/p'
which will produce output of the form
#include "..." search starts here:
#include <...> search starts here:
/usr/lib/gcc/x86_64-linux-gnu/5/include
/usr/local/include
/usr/lib/gcc/x86_64-linux-gnu/5/include-fixed
/usr/include/x86_64-linux-gnu
/usr/include
End of search list.
If you have -I
-family options on the command line they will affect what is printed out.
(The sed
command is to get rid of all the other junk this invocation prints, and the LC_ALL=C
is to ensure that the sed
command works -- the "starts here" and "End of search list" phrases are translated IIRC.)
Keep in mind that a cookie is actually defined by the tuple of it's name, path, and domain. If any one of those three is different, or there is more than one cookie of the same name, but defined with paths/domains that may still be visible for the URL in question, you'll still see that cookie passed on the request. E.g. if the url is "http://foo.bar.com/baz/index.html", you'll see any cookies defined on bar.com or foo.bar.com, or with a path of "/" or "/baz".
Thus, what you have looks like it should work, as long as there's only one cookie defined in the client, with the name "SSO_COOKIE_NAME", domain "SSO_DOMAIN", and path "/". If there are any cookies with different path or domain, you'll still see the cookie sent to the client.
To debug this, go into Firefox's preferences -> Security tab, and search for all cookies with the SSO_COOKIE_NAME. Click on each to see the domain and path. I'm betting you'll find one in there that's not quite what you're expecting.
You can make use of
display: flex;
align-items: center;
justify-content: center;
on your parent component
You can replace the src/main/resources/
directly by classpath:
So for your example you will replace this line:
new BufferedReader(new FileReader(new File("src/main/resources/config.txt")));
By this line:
new BufferedReader(new FileReader(new File("classpath:config.txt")));
There is no difference between US ASCII and UTF-8, so there isn't any need to reconvert it.
But here a little hint, if you have trouble with special-chars while recoding.
Add //TRANSLIT after the source-charset-Parameter.
Example:
iconv -f ISO-8859-1//TRANSLIT -t UTF-8 filename.sql > utf8-filename.sql
This helps me with strange types of quotes, which are always breaking the character set reencode process.
I dont know if you want to achieve that in js or java, in js the simplest way to get the unix timestampt (this is time in seconds from 1/1/1970) it's as follows:
var myDate = new Date();
console.log(+myDate); // +myDateObject give you the unix from that date
Give name and values to those submit buttons like:
<td>
<input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
</td>
<td>
<input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
</td>
and then in your php script you could check
if($_POST['mybutton'] == 'save')
{
///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
///do publish processing here
}
Have no idea about gd2, but I have done a similar thing with gd and it was not that hard.
Go to http://www.php.net/ and search for things like
It's not as flashy as some of those other solution out there, but since you generate a picture it will work in all browsers. (except lynx... :-) )

Update: I nearly forgot, don't use jpeg for this type of pictures. The jpeg artefacts will be really annoying, png is a better solution.

Edit: working example, http://jsfiddle.net/C5WxK/
def in_unix(input):
start = datetime.datetime(year=1970,month=1,day=1)
diff = input - start
return diff.total_seconds()
It really depends on what you want to do with that exception after you catch it. If you need to differentiate your exception then you have to create your custom Exception
. Otherwise you could just throw new Exception("message goes here");
In my case, I have Jackson automatically (de)serializing objects that I return from a Spring MVC controller (I am using @RestController with Spring 4.1.6). I had to use com.fasterxml.jackson.annotation.JsonIgnore
instead of org.codehaus.jackson.annotate.JsonIgnore
, as otherwise, it simply did nothing.
You can use .shape
In: a = np.array([[1,2,3],[4,5,6]])
In: a.shape
Out: (2, 3)
In: a.shape[0] # x axis
Out: 2
In: a.shape[1] # y axis
Out: 3
the easiest hack is to set a min-height
to your page container at 400px assuming your footer come at the end. you dont even have to put css for the footer or just a width:100%
assuming your footer is direct child of your <body>
public int read(byte[] a) throws IOException {
try {
return in.read(a);
} catch (final Throwable t) {
/* can do something here, like in=null; */
throw t;
}
}
This is a concrete example where the method throws an IOException
. The final
means t
can only hold an exception thrown from the try block. Additional reading material can be found here and here.
Use:
function Which([string] $cmd) {
$path = (($Env:Path).Split(";") | Select -uniq | Where { $_.Length } | Where { Test-Path $_ } | Get-ChildItem -filter $cmd).FullName
if ($path) { $path.ToString() }
}
# Check if Chocolatey is installed
if (Which('cinst.bat')) {
Write-Host "yes"
} else {
Write-Host "no"
}
Or this version, calling the original where command.
This version also works better, because it is not limited to bat files:
function which([string] $cmd) {
$where = iex $(Join-Path $env:SystemRoot "System32\where.exe $cmd 2>&1")
$first = $($where -split '[\r\n]')
if ($first.getType().BaseType.Name -eq 'Array') {
$first = $first[0]
}
if (Test-Path $first) {
$first
}
}
# Check if Curl is installed
if (which('curl')) {
echo 'yes'
} else {
echo 'no'
}
So that its value can easily contain quotes and <> characters and respect whitespace and newlines.
The following HTML code successfully pass the w3c validator and displays <,> and & without the need to encode them. It also respects the white spaces.
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Yes I can</title>
</head>
<body>
<textarea name="test">
I can put < and > and & signs in
my textarea without any problems.
</textarea>
</body>
</html>
You can look at the Django framework for how they create a "slug" from arbitrary text. A slug is URL- and filename- friendly.
The Django text utils define a function, slugify()
, that's probably the gold standard for this kind of thing. Essentially, their code is the following.
import unicodedata
import re
def slugify(value, allow_unicode=False):
"""
Taken from https://github.com/django/django/blob/master/django/utils/text.py
Convert to ASCII if 'allow_unicode' is False. Convert spaces or repeated
dashes to single dashes. Remove characters that aren't alphanumerics,
underscores, or hyphens. Convert to lowercase. Also strip leading and
trailing whitespace, dashes, and underscores.
"""
value = str(value)
if allow_unicode:
value = unicodedata.normalize('NFKC', value)
else:
value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore').decode('ascii')
value = re.sub(r'[^\w\s-]', '', value.lower())
return re.sub(r'[-\s]+', '-', value).strip('-_')
And the older version:
def slugify(value):
"""
Normalizes string, converts to lowercase, removes non-alpha characters,
and converts spaces to hyphens.
"""
import unicodedata
value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore')
value = unicode(re.sub('[^\w\s-]', '', value).strip().lower())
value = unicode(re.sub('[-\s]+', '-', value))
# ...
return value
There's more, but I left it out, since it doesn't address slugification, but escaping.
You need to clone in ssh not in https.
For that you need to set your ssh keys. I have prepared this little script that automates this:
#!/usr/bin/env bash
email="$1"
hostname="$2"
hostalias="$hostname"
keypath="$HOME/.ssh/${hostname}_rsa"
ssh-keygen -t rsa -C $email -f $keypath
if [ $? -eq 0 ]; then
cat >> ~/.ssh/config <<EOF
Host $hostalias
Hostname $hostname *.$hostname
User git
IdentitiesOnly yes
IdentityFile $keypath
EOF
fi
and run it like
bash script.sh [email protected] github.com
Change your remote url
git remote set-url origin [email protected]:user/foo.git
Add content of ~/.ssh/github.com_rsa.pub
to your ssh keys on github.com
Check connection
ssh -T [email protected]
You can save Base64 directly into file:
string filePath = "MyImage.jpg";
File.WriteAllBytes(filePath, Convert.FromBase64String(base64imageString));
If your Linux system supports it, clock_gettime(CLOCK_MONOTONIC) should be a high resolution timer that is unaffected by system date changes (e.g. NTP daemons).
As per the documentation, these are just synonyms. size()
is there to be consistent with other STL containers (like vector
, map
, etc.) and length()
is to be consistent with most peoples' intuitive notion of character strings. People usually talk about a word, sentence or paragraph's length, not its size, so length()
is there to make things more readable.
If you are planning a public facing web site then you should not go with either option. Your should use a Content Delivery Network (CDN). There are price, scalability and speed advantages to a CDN when delivering a large amount of static content over the internet.
If you want to display an image file on the phone, you can do this:
private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);
mImageView.setImageBitmap(BitmapFactory.decodeFile("pathToImageFile"));
If you want to display an image from your drawable resources, do this:
private ImageView mImageView;
mImageView = (ImageView) findViewById(R.id.imageViewId);
mImageView.setImageResource(R.drawable.imageFileId);
You'll find the drawable
folder(s) in the project res
folder. You can put your image files there.
Change the directory of the Project and re-open.
Four fewer characters, but 2 more ms
%%timeit
df.isna().T.any()
# 52.4 ms ± 352 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

I'd probably use axis=1
In Stored procedure, you return the values using OUT
parameter ONLY. As you have defined two variables in your example:
outstaticip OUT VARCHAR2, outcount OUT NUMBER
Just assign the return values to the out parameters i.e. outstaticip
and outcount
and access them back from calling location. What I mean here is: when you call the stored procedure, you will be passing those two variables as well. After the stored procedure call, the variables will be populated with return values.
If you want to have RETURN value
as return from the PL/SQL call, then use FUNCTION
. Please note that in case, you would be able to return only one variable as return variable.
Just building on the work of others here:
[String] ${stUserDomain},[String] ${stUserAccount} = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name.split("\")
You could create a function that checks every input in an input class like below
function validateForm() {
var anyFieldIsEmpty = jQuery(".myclass").filter(function () {
return $.trim(this.value).length === 0;
}).length > 0
if (anyFieldIsEmpty) {
alert("Fill all the necessary fields");
var empty = $(".myclass").filter(function () {
return $.trim(this.value).length === 0;
})
empty.css("border", "1px solid red");
return false;
} else {
return true;
}
}
What this does is it checks every input in 'myclass' and if empty it gives alert and colour the border of the input and user will recognize which input is not filled.

For some reasons, Webkit-based browsers don't follow the spec for the dialog box. An almost cross-working example would be close from the below example.
window.addEventListener("beforeunload", function (e) {
var confirmationMessage = "\o/";
(e || window.event).returnValue = confirmationMessage; //Gecko + IE
return confirmationMessage; //Webkit, Safari, Chrome
});
This example for handling all browsers.
In my case this was happening with a Laravel queue worker. The system logs did not mention any killing so I looked further and it turned out that the worker was basically killing itself because of a job that exceeded the memory limit (which is set to 128M by default).
Running the queue worker with --timeout=600
and --memory=1024
fixed the problem for me.
Quite often the issue is a non-breaking space - CHAR(160)
- especially from Web text sources -that CLEAN
can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one
=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))
Ron de Bruin has an excellent post on tips for cleaning data here
You can also remove the CHAR(160)
directly without a workaround formula by
ALT
and type 0160
using the numeric keypadTry writing a Unit Test before writing the method it is going to test.
That will definitely force you to think a little differently about how things are being done. You'll have no idea how the method is going to work, just what it is supposed to do.
You should always be testing the results of the method, not how the method gets those results.
df.category.value_counts()
This short little line of code will give you the output you want.
If your column name has spaces you can use
df['category'].value_counts()
A simple thing to do when you realize you just typed the wrong line is hit Ctrl+C; if you want to keep the line, but need to execute something else first, begin a new line with a back slash - \, then Ctrl+C. The line will remain in your history.
Sorry to break the news to ya, but there is no way to do this in IE11. I have been troubling with this for some time, but I finally had to see it as a lost course, and just navigate to the files manually.
But where are the files? That depends on a lot of things, I have found them these places on different machines:
This can be done via "run" (Windows+r) and then typing in shell:cache
or by navigating to it through the internet options in IE11 (AskLeo has a fine guide to this, I'm not affiliated in any way).
- Click on the gear icon, then Internet options.
- In the General tab, underneath “Browsing history”, click on Settings.
- In the resulting “Website Data” dialog, click on View files.
- This will open the folder we’re interested in: your Internet Explorer cache.

There is a class in accordian which just adjust height from height:auto or 0 to the accordian div.
if you remove 'in' class and when you click on it, bootstrap adds 'in' class again and now content will be visible
<div id="collapseOne" class="accordion-body collapse">
....

Here's my solution! Windows 10, Python 3.7.1
I'm not sure why this code works, but it completely erases the original line. I compiled it from the previous answers. The other answers would just return the line to the beginning, but if you had a shorter line afterwards, it would look messed up like hello
turns into byelo
.
import sys
#include ctypes if you're on Windows
import ctypes
kernel32 = ctypes.windll.kernel32
kernel32.SetConsoleMode(kernel32.GetStdHandle(-11), 7)
#end ctypes
def clearline(msg):
CURSOR_UP_ONE = '\033[K'
ERASE_LINE = '\x1b[2K'
sys.stdout.write(CURSOR_UP_ONE)
sys.stdout.write(ERASE_LINE+'\r')
print(msg, end='\r')
#example
ig_usernames = ['beyonce','selenagomez']
for name in ig_usernames:
clearline("SCRAPING COMPLETE: "+ name)
Output - Each line will be rewritten without any old text showing:
SCRAPING COMPLETE: selenagomez
Next line (rewritten completely on same line):
SCRAPING COMPLETE: beyonce
a {

Absolutely, positively option A. Others have mentioned that databases generally don't deal well with BLOBs, whether they're designed to do so or not. Filesystems, on the other hand, live for this stuff. You have the option of using RAID striping, spreading images across multiple drives, even spreading them across geographically disparate servers.
Another advantage is your database backups/replication would be monstrous.
A few comments:
analog=True
in the call to butter
, and you should use scipy.signal.freqz
(not freqs
) to generate the frequency response.Here's my modified version of your script, followed by the plot that it generates.
import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt
def butter_lowpass(cutoff, fs, order=5):
nyq = 0.5 * fs
normal_cutoff = cutoff / nyq
b, a = butter(order, normal_cutoff, btype='low', analog=False)
return b, a
def butter_lowpass_filter(data, cutoff, fs, order=5):
b, a = butter_lowpass(cutoff, fs, order=order)
y = lfilter(b, a, data)
return y
# Filter requirements.
order = 6
fs = 30.0 # sample rate, Hz
cutoff = 3.667 # desired cutoff frequency of the filter, Hz
# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)
# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()
# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0 # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data. We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)
# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)
plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()
plt.subplots_adjust(hspace=0.35)

public byte[] longToBytes(long x) {
ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
buffer.putLong(x);
return buffer.array();
}
public long bytesToLong(byte[] bytes) {
ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
buffer.put(bytes);
buffer.flip();//need flip
return buffer.getLong();
}
Or wrapped in a class to avoid repeatedly creating ByteBuffers:
public class ByteUtils {
private static ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
public static byte[] longToBytes(long x) {
buffer.putLong(0, x);
return buffer.array();
}
public static long bytesToLong(byte[] bytes) {
buffer.put(bytes, 0, bytes.length);
buffer.flip();//need flip
return buffer.getLong();
}
}
Since this is getting so popular, I just want to mention that I think you're better off using a library like Guava in the vast majority of cases. And if you have some strange opposition to libraries, you should probably consider this answer first for native java solutions. I think the main thing my answer really has going for it is that you don't have to worry about the endian-ness of the system yourself.
I ran into this on my Mac using the MacPorts vim with +python. Problem was that the MacPorts vim will only bind to python 2.5 with +python, while my extensions were installed under python 2.7. Installing the extensions using pip-2.5 solved it.
Yes, it is important if your item will be used as a key in a dictionary, or HashSet<T>
, etc - since this is used (in the absence of a custom IEqualityComparer<T>
) to group items into buckets. If the hash-code for two items does not match, they may never be considered equal (Equals will simply never be called).
The GetHashCode() method should reflect the Equals
logic; the rules are:
Equals(...) == true
) then they must return the same value for GetHashCode()
GetHashCode()
is equal, it is not necessary for them to be the same; this is a collision, and Equals
will be called to see if it is a real equality or not.In this case, it looks like "return FooId;
" is a suitable GetHashCode()
implementation. If you are testing multiple properties, it is common to combine them using code like below, to reduce diagonal collisions (i.e. so that new Foo(3,5)
has a different hash-code to new Foo(5,3)
):
unchecked // only needed if you're compiling with arithmetic checks enabled
{ // (the default compiler behaviour is *disabled*, so most folks won't need this)
int hash = 13;
hash = (hash * 7) + field1.GetHashCode();
hash = (hash * 7) + field2.GetHashCode();
...
return hash;
}
Oh - for convenience, you might also consider providing ==
and !=
operators when overriding Equals
and GetHashCode
.
A demonstration of what happens when you get this wrong is here.
To start with you can't do this:
having rid!=MAX(rid)
The HAVING clause can only contain things which are attributes of the aggregate groups.
In addition, 1, 2, 3
is not valid in GROUP BY in SQL Server - I think that's only valid in ORDER BY.
Can you explain why this isn't what you are looking for:
select
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid)
from batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where LEN(datapath)>4
group by LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound
Yet another Googlemare Landmine.... Somehow, if you mess up, the icon line on your .gen file dies. (Empirical proof of mine after struggling 2 hours)
Insert a new icon 72x72 icon on the hdpi folder with a different name from the original, and update the name on the manifest also.
The icon somehow resurrects on the Gen file and voila!! time to move on.
You have a view model to which your view is strongly typed => use strongly typed helpers:
<%= Html.DropDownListFor(
x => x.SelectedAccountId,
new SelectList(Model.Accounts, "Value", "Text")
) %>
Also notice that I use a SelectList
for the second argument.
And in your controller action you were returning the view model passed as argument and not the one you constructed inside the action which had the Accounts property correctly setup so this could be problematic. I've cleaned it a bit:
public ActionResult AccountTransaction()
{
var accounts = Services.AccountServices.GetAccounts(false);
var viewModel = new AccountTransactionView
{
Accounts = accounts.Select(a => new SelectListItem
{
Text = a.Description,
Value = a.AccountId.ToString()
})
};
return View(viewModel);
}
gevang's answer is great. There's another way as well to do this directly by using pcolor
. Code:
[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
figure;
subplot(1,3,1);
pcolor(X,Y,Z);
subplot(1,3,2);
pcolor(X,Y,Z); shading flat;
subplot(1,3,3);
pcolor(X,Y,Z); shading interp;
Output:
Also, pcolor
is flat too, as show here (pcolor
is the 2d base; the 3d figure above it is generated using mesh
):
def trim(x):
if x.dtype == object:
x = x.str.split(' ').str[0]
return(x)
df = df.apply(trim)
For hiding the toolbar you can just do :
getSupportActionBar().hide();
So you just have to had a scroll listener and hide the toolbar when the user scroll !
If, like me, you prefer to deal with strongly typed objects** go with:
MyObj obj = JsonConvert.DeserializeObject<MyObj>(jsonString);
This way you get to use intellisense and compile time type error checking.
You can easily create the required objects by copying your JSON into memory and pasting it as JSON objects (Visual Studio -> Edit -> Paste Special -> Paste JSON as Classes).
See here if you don't have that option in Visual Studio.
You will also need to make sure your JSON is valid. Add your own object at the start if it is just an array of objects. i.e. {"obj":[{},{},{}]}
** I know that dynamic makes things easier sometimes but I'm a bit ol'skool with this.
SELECT * FROM `calendar` WHERE startTime like '2010-04-29%'
You can also use comparison operators on MySQL dates if you want to find something after or before. This is because they are written in such a way (largest value to smallest with leading zeros) that a simple string sort will sort them correctly.
Modern approach.
let c = document.cookie.split(";").reduce( (ac, cv, i) => Object.assign(ac, {[cv.split('=')[0]]: cv.split('=')[1]}), {});
console.log(c);
;)

A trivial change (to a resoruce xml) still took 10 minutes.
As @rivare says in his answer, a command line build is mutch faster (took this down to 15 seconds).
Here are some steps to at least make a trivial build fast from the command line for Windows.
Go to your projects root (where the gradlew.bat is):
cd c:\android\MaskActivity
execute the build:
gradlew assembleDebug
uninstall the apk from the phone directly (drag it to uninstall).
When the build is finished, kill the BIG java process using Windows Task Manager.
OR if you have unix tools on your Windows machine:
ps
"pid" 's are shown:
kill -9 <pid>
Now install your apk:
adb -d install C:\Android\MaskActivity\app\build\outputs\apk\app-debug.apk
You can do like this
SELECT something
FROM
(a LEFT JOIN b ON a.a_id = b.b_id) LEFT JOIN c on a.a_aid = c.c_id
WHERE a.parent_id = 'rootID'
When you create a new CMS block named block_identifier from the admin panel you can use the following code to call it from your .phtml file:
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block_identifier')->toHtml();
?>
Then clear the cache and reload your browser.
"JSON has a special value called null which can be set on any type of data including arrays, objects, number and boolean types."
"The JSON empty concept applies for arrays and objects...Data object does not have a concept of empty lists. Hence, no action is taken on the data object for those properties."
Here is my source.
The out
and the ref
parameters are used to return values in the same variable, that you pass as an argument of a method. These both parameters are very useful when your method needs to return more than one value.
You must assigned value to out parameter in calee method body, otherwise the method won't get compiled.
Ref Parameter : It has to be initialized before passing to the Method. The
ref
keyword on a method parameter causes a method to refer to the same variable that was passed as an input parameter for the same method. If you do any changes to the variable, they will be reflected in the variable.int sampleData = 0; sampleMethod(ref sampleData);
Ex of Ref Parameter
public static void Main()
{
int i = 3; // Variable need to be initialized
sampleMethod(ref i );
}
public static void sampleMethod(ref int sampleData)
{
sampleData++;
}
Out Parameter : It is not necessary to be initialized before passing to Method. The
out
parameter can be used to return the values in the same variable passed as a parameter of the method. Any changes made to the parameter will be reflected in the variable.int sampleData; sampleMethod(out sampleData);
Ex of Out Parameter
public static void Main()
{
int i, j; // Variable need not be initialized
sampleMethod(out i, out j);
}
public static int sampleMethod(out int sampleData1, out int sampleData2)
{
sampleData1 = 10;
sampleData2 = 20;
return 0;
}
The trick is to read the declaration backwards (right-to-left):
const int a = 1; // read as "a is an integer which is constant"
int const a = 1; // read as "a is a constant integer"
Both are the same thing. Therefore:
a = 2; // Can't do because a is constant
The reading backwards trick especially comes in handy when you're dealing with more complex declarations such as:
const char *s; // read as "s is a pointer to a char that is constant"
char c;
char *const t = &c; // read as "t is a constant pointer to a char"
*s = 'A'; // Can't do because the char is constant
s++; // Can do because the pointer isn't constant
*t = 'A'; // Can do because the char isn't constant
t++; // Can't do because the pointer is constant
I've done it before, I just used:
down.setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
return true;
}
});
Per documentation:
public void setOnLongClickListener (View.OnLongClickListener l)
Since: API Level 1 Register a callback to be invoked when this view is clicked and held. If this view is not long clickable, it becomes long clickable.
Notice that it requires to return a boolean, this should work.
these are controlled in variables, no need to muck around in source. with bootstrap, try variables first, then overrides. then go back and try variables again ;)
i used bootstrap-sass with rails, but it's the same with the default LESS.
FILE: main.css.scss
-------------------
// control the screen sizes
$screen-xs-min: 300px;
$screen-sm-min: 400px;
$screen-md-min: 800px;
$screen-lg-min: 1200px;
// this tells which screen size to use to start breaking on
// will tell navbar when to collapse
$grid-float-breakpoint: $screen-md-min;
// then import your bootstrap
@import "bootstrap";
that's it! this variables reference page is super handy: https://github.com/twbs/bootstrap/blob/master/less/variables.less
Scenario A: If your large files were only added to a branch, you don't need to run git filter-branch
. You just need to delete the branch and run garbage collection:
git branch -D mybranch
git reflog expire --expire-unreachable=all --all
git gc --prune=all
Scenario B: However, it looks like based on your bash history, that you did merge the changes into master. If you haven't shared the changes with anyone (no git push
yet). The easiest thing would be to reset master back to before the merge with the branch that had the big files. This will eliminate all commits from your branch and all commits made to master after the merge. So you might lose changes -- in addition to the big files -- that you may have actually wanted:
git checkout master
git log # Find the commit hash just before the merge
git reset --hard <commit hash>
Then run the steps from the scenario A.
Scenario C: If there were other changes from the branch or changes on master after the merge that you want to keep, it would be best to rebase master and selectively include commits that you want:
git checkout master
git log # Find the commit hash just before the merge
git rebase -i <commit hash>
In your editor, remove lines that correspond to the commits that added the large files, but leave everything else as is. Save and quit. Your master branch should only contain what you want, and no large files. Note that git rebase
without -p
will eliminate merge commits, so you'll be left with a linear history for master after <commit hash>
. This is probably okay for you, but if not, you could try with -p
, but git help rebase
says combining -p with the -i option explicitly is generally not a good idea unless you know what you are doing
.
Then run the commands from scenario A.

That's not work on option
entry because it's a "system" generated drop-down menu but you can set the padding
of a select.
Just reset the box-sizing
property to content-box
in your CSS.
The default value of select
is border-box
.
select {
box-sizing: content-box;
padding: 5px 0;
}
I just faced this issue, doing some research I found that the data values has to be sended as URLSearchParams, I do it like this:
getAuthToken: async () => {
const data = new URLSearchParams();
data.append('grant_type', 'client_credentials');
const fetchAuthToken = await axios({
url: `${PAYMENT_URI}${PAYMENT_GET_TOKEN_PATH}`,
method: 'POST',
auth: {
username: PAYMENT_CLIENT_ID,
password: PAYMENT_SECRET,
},
headers: {
Accept: 'application/json',
'Accept-Language': 'en_US',
'Content-Type': 'application/x-www-form-urlencoded',
'Access-Control-Allow-Origin': '*',
},
data,
withCredentials: true,
});
return fetchAuthToken;
},
In simple terms, inside a then
handler function:
A) When x
is a value (number, string, etc):
return x
is equivalent to return Promise.resolve(x)
throw x
is equivalent to return Promise.reject(x)
B) When x
is a Promise that is already settled (not pending anymore):
return x
is equivalent to return Promise.resolve(x)
, if the Promise was already resolved.return x
is equivalent to return Promise.reject(x)
, if the Promise was already rejected.C) When x
is a Promise that is pending:
return x
will return a pending Promise, and it will be evaluated on the subsequent then
. Read more on this topic on the Promise.prototype.then() docs.
Because I am pre-compiling my web application (using VS2012 publish feature). I was getting the error above. I tried all the suggestions, but weirdly changing 'Build Action' to 'Content' did the trick!
nslookup google.com
is the easiest way. Works on Linux and Windows.
If your issue is that your DNS server is not returning a response for google.com, use a different DNS server, such as a public one. For instance, you could do:
nslookup
>server 8.8.8.8
>google.com
For a more thorough solution to getting around annoying Internet filters, look into using Tor.
The stuff between the
-----BEGIN RSA PRIVATE KEY----
and
-----END RSA PRIVATE KEY-----
is the base64 encoding of a PKCS#8 PrivateKeyInfo (unless it says RSA ENCRYPTED PRIVATE KEY in which case it is a EncryptedPrivateKeyInfo).
It is not that hard to decode manually, but otherwise your best bet is to P/Invoke to CryptImportPKCS8.
Update: The CryptImportPKCS8 function is no longer available for use as of Windows Server 2008 and Windows Vista. Instead, use the PFXImportCertStore function.
This is considered as features in Gitlab.
